ABSTRACT

Objective To investigate the changes in the awareness rate of Taenia solium taeniasis and cysticercosis control knowledge among medical professionals before and after training in Fangcheng County, a disease-elimination pilot area of Henan Province, so as to evaluate the effectiveness of the training. Methods Three townships in Fangcheng County were randomly selected as the study townships, including Dushu, Bowang and Yangji townships, while Erlangmiao, Yanglou and Xiaoshidian townships in the county were randomly selected as the control townships. The grassroots medical professionals in the study townships were given once training on T. solium taeniasis and cysticercosis control knowledge each year from 2016 to 2020, while those in the control townships were given no interventions. All village-level doctors and a part of township-level public health professionals were sampled from the study and control townships as intervention and control groups. The baseline and final assessments of the awareness of T. solium taeniasis and cysticercosis control knowledge were performed using questionnaire survey in intervention and control groups in 2016 and 2020, and the awareness of T. solium taeniasis and cysticercosis control knowledge was compared between the two groups. Results A total of 663 medical professionals were investigated in Fangcheng County from 2016 to 2020, including 474 participants in the intervention group and 189 participants in the control group. Results from the 2016 baseline survey showed that the awareness rate of T. solium taeniasis and cysticercosis control knowledge was 28.83% (47/163) among grassroots medical professionals in Fangcheng County, and there were no significant differences in the awareness between the intervention (32.47%, 25/77) and control groups (25.58%, 22/86) (χ2 = 0.939, P > 0.05), between men (30.50%, 43/141) and women (18.18%, 4/22) (χ2 = 1.406, P > 0.05) or between village- (31.39%, 43/137) and township-level medical professionals (15.38%, 4/26) (χ2 = 2.727, P > 0.05), while significant differences were found in the awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in terms of education levels (χ2 = 8.190, P < 0.05) and duration of working experiences (χ2 = 12.617, P < 0.05), and the awareness rate of T. solium taeniasis and cysticercosis control knowledge increased with education levels among medical professionals (χ2 = 6.768, P < 0.05). Only 5.52% (9/163) of the medical professionals had a history of diagnosis and therapy of T. solium taeniasis or cysticercosis, and only 1.23% (2/163) received training on T. solium taeniasis and cysticercosis control knowledge during the past 5 years. Results from the 2020 questionnaire survey showed a higher awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in the intervention group (93.55%, 116/124) than in the control group (46.60%, 48/103) (χ2 = 61.845, P < 0.05), and no significant differences were seen in the awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in terms of gender, level of medical professionals, duration of working experiences or history of diagnosis/therapy of T. solium taeniasis and cysticercosis in the intervention group (χ2 = 1.089, 0.140, 0.081 and 0.453, all P values > 0.05), while there was a significant difference in the awareness rate among medical professionals with different education levels (χ2 = 36.338, P < 0.05). In addition, the awareness rate of T. solium taeniasis and cysticercosis control knowledge significantly increased among medical professionals with various chracteristics in 2020 than in 2016. Conclusions In the low-prevalence areas of T. solium taeniasis and cysticercosis, long-term and persistent training may improve the awareness of T. solium taeniasis and cysticercosis control knowledge among grassroots medical professionals, which facilitates the timely identification of T. solium taeniasis and cysticercosis and the establishment of a sensitive disease surveillance system.

ABSTRACT

ObjectiveTo reveal the medication rules of the clinical prescriptions containing Citri Sarcodactylis Fructus, and to provide a basis for the modern clinical application of Citri Sarcodactylis Fructus, the development of health products and the research and development of new drugs. MethodThe clinical prescriptions containing Citri Sarcodactylis Fructus were retrieved from CNKI, Wanfang Data, and VIP, and then a basic database of prescriptions was established via the traditional Chinese medicine inheritance auxiliary platform (V2.5), IBM SPSS V20, and Excel (Microsoft Office 2016). The frequency and association rules of the medicines in prescriptions (compatible medicines) and the corresponding syndromes were then mined. ResultThe prescriptions were screened according to the inclusion and exclusion criteria. A total of 458 clinical prescriptions containing Citri Sarcodactylis Fructus were collected, involving 388 Chinese medicines, and the total frequency of medicines reached 6 199. The core compatible medicines (frequency > 130) of Citri Sarcodactylis Fructus included Poria (frequency of 222), Atractylodis Macrocephalae Rhizoma (217), Paeoniae Radix Alba (196), Bupleuri Radix (159), and Citri Reticulatae Pericarpium (142). The Citri Sarcodactylis Fructus-compatible medicines with frequency > 49 were selected for further analysis, which included 34 medicines with the cumulative frequency of 3 131 (50.51% of the total frequency). These medicines mainly have the functions of tonifying Qi, invigorating Qi, tonifying blood, alleviating edema and promoting urination, promoting digestion, and activating blood and relieving pain. They are mainly warm, cold, or mild-natured, taste bitter, sweet, or acrid, and have the tropism in the spleen, liver, stomach, or lung meridians. The association rule analysis demonstrated that 14 medicine combinations were commonly used, and the core combinations were Poria-Citri Sarcodactylis Fructus, Atractylodis Macrocephalae Rhizoma-Citri Sarcodactylis Fructus, Paeoniae Radix Alba-Citri Sarcodactylis Fructus, Bupleuri Radix-Citri Sarcodactylis Fructus, Atractylodis Macrocephalae Rhizoma-Poria-Citri Sarcodactylis Fructus, and Citri Reticulatae Pericarpium-Citri Sarcodactylis Fructus. The clinical prescriptions containing Citri Sarcodactylis Fructus were mainly used to treat 52 diseases corresponding to 11 types of traditional Chinese medicine (TCM) syndromes. Three representative syndrome types, including spleen and stomach syndromes, Qi-blood-body fluid syndromes, and gynecological syndromes were selected for further association rule analysis. In the treatment of spleen and stomach syndromes, the core compatible drugs were Atractylodis Macrocephalae Rhizoma, Poria, Paeoniae Radix Alba, Bupleuri Radix, Citri Reticulatae Pericarpium, and Pinelliae Ehizoma, which, together with Citri Sarcodactylis Fructus, formed 25 commonly used medicine combinations (16 combinations composed of 2 medicines and 9 combinations composed of 3 medicines). In the treatment of Qi-blood-body fluid syndromes, the core compatible drugs were Poria, Paeoniae Radix Alba, Atractylodis Macrocephalae Rhizoma, Astragali Radix, Hordei Fructus Germinatus, and Bupleuri Radix, which, together with Citri Sarcodactylis Fructus, formed 23 common medicine combinations (17 combinations composed of 2 medicines, 5 combinations composed of 3 medicines, and 1 combination composed of 4 medicines). In the treatment of gynecological syndromes, the core compatible medicines were Atractylodis Macrocephalae Rhizoma, Paeoniae Radix Alba, Angelicae Sinensis Radix, Astragali Radix, Cyperi Rhizoma, and Poria, which constituted 25 common medicine combinations (15 combinations composed of 2 medicines and 10 combinations composed of 3 medicines). ConclusionWe employed the traditional Chinese medicine(TCM) inheritance auxiliary platform to explore the compatibility of Citri Sarcodactylis Fructus-containing clinical prescriptions and the corresponding TCM syndromes, which intuitively showcased the medication rules of Citri Sarcodactylis Fructus. Specifically, Citri Sarcodactylis Fructus was mainly combined with the medicines for tonifying Qi, invigorating Qi, tonifying blood, alleviating edema and promoting urination, promoting digestion, and activating blood and relieving pain to treat different TCM syndromes. While soothing liver, regulating Qi, harmonizing stomach, and relieving pain, the combinations tonify and activate blood, invigorate spleen, and resolve dampness. The findings are of great significance to the rational application of Citri Sarcodactylis Fructus, the development of health food, and the research of new drugs and will bolster the development of Chinese medicine industry.

ABSTRACT

Standardized surgical management of postoperative specimens of gastric cancer is an important part of the standardized diagnosis and treatment of gastric cancer. It can reflect the accurate number and detailed distribution of lymph nodes in the specimen and lay the foundation for accurate and standardized pathological reports after surgery. Meanwhile, it can evaluate the scope of intraoperative lymph node dissection, the safety of cutting edge, and the standardization of surgery (principle of en-bloc dissection), which is an important means of surgical quality control. It also provides accurate research samples for further research and is an important way for young surgeons to train their clinical skills. The surgical management of postoperative specimens for gastric cancer needs to be standardized, including specimen processing personnel, processing flow, resection margin examination, lymph node sorting, measurement after specimen dissection, storage of biological specimens, documentation of recorded data, etc. The promotion of standardized surgical management of specimens after radical gastrectomy can promote the homogenization of gastric cancer surgical diagnosis and treatment in medical institutions and further promote the high-quality development of gastric cancer surgery in China.

ABSTRACT

Objective: To explore the time series characteristics of hepatitis C cases in children aged ≤14 years old in Henan and predict their epidemic situation with effective model. Methods: Hepatitis C reported data among children aged ≤14 years old in Henan from 2005 to 2020 were collected from China information system for diseases control and prevention. Descriptive and time series analyses were used to demonstrate characteristics of time trend, decomposition methods were used to show the seasonality by using seasonal indices and the long-term trend by using a linear regression model. An auto-regressive integrated moving average (ARIMA) model was established. Results: From 2005 to 2020, a total of 5 355 hepatitis C cases in children were reported in Henan, the seasonal index range of the hepatitis C was lower than 1, and no obvious seasonality characteristics was observed. The average of monthly incidence of 2005-2011 showed increase trend (0.351 case/month), and the incidence of 2012-2020 decreased (-0.474 case/month). The predicted reported case number of hepatitis C in children in Henan from January 2005 to December 2020 fitted by ARIMA model was consistent with the actual number, the RMSE of the number of reported cases in the current year and the existing number of children cases was 10.240, 10.558, the MAPE was 35.566, 0.659, and the MAE was 6.688, 7.156, respectively. Conclusion: Time series analysis on surveillance data is useful for the better understanding of the epidemic situation of hepatitis C in children aged ≤14 years. ARIMA model can be used in the short-term prediction and dynamic analysis of the incidence of hepatitis C in children in Henan.

ABSTRACT

Objective:To establish the normal values of water-perfused high resolution esophageal manometry (HREM)(GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing in Chinese population.Methods:From September 1, 2019 to June 30, 2020, 91 healthy volunteers receiving water-perfused HREM (GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing were selected from 9 hospitals (Union Hospital, Tongji Medical College, Huazhong University of Science and Technology; the First Affiliated Hospital of Dalian Medical University; the Second Hospital of Hebei Medical University; the Second Affiliated Hospital, Naval Medical University; the First Affiliated Hospital, Sun Yat-sen University; the First Affiliated Hospital, University of Science and Technology of China; Aviation General Hospital of China Medical University; the Affiliated Hospital of Medical School of Nanjing University and the First People′s Hospital of Yichang). Parameters included the position of the upper and lower edges of the upper esophageal sphincter (UES) and lower esophageal sphincter (LES), the length of the LES and UES, the position of the pressure inversion point (PIP), the resting pressure of UES and LES and swallow-related parameters such as the distal contraction integral (DCI), 4 s integrated relaxation pressure (IRP), distal latency (DL) and UES residual pressure. One-way analysis of variance, post-hoc test and sum rank test were used for statistical analysis.Results:A total of 87 healthy volunteers were enrolled, including 40 males and 47 females, aged (38.5±14.2) years old (ranged from 19 to 65 years old). The position of the upper and lower edges of the LES was (42.7±2.8) and (45.6±2.8) cm, respectively, the length of the LES was (2.9±0.4) cm, and the position of PIP was (43.3±2.8) cm. The position of the upper and lower edges of the UES was (18.1±3.0) and (22.6±2.0) cm, respectively, and the length of the UES was (4.8±1.0) cm. The resting pressure of LES and UES was (17.4±10.7) and (84.1±61.1) mmHg (1 mmHg=0.133 kPa), respectively. The DCI value at solid swallowing was higher than those at water swallowing and semisolid swallowing ((2 512.4±1 448.0) mmHg·s·cm vs. (2 183.2±1 441.2) and (2 150.8±1 244.8) mmHg·s·cm), and the differences were statistically significant ( t=-4.30 and -3.74, both P<0.001). The values of 4 s IRP at semisolid swallowing and solid swallowing were lower than that at water swallowing ((4.6±4.1) and (4.9±3.9) mmHg vs. (5.4±3.9) mmHg), and the differences were statistically significant ( t=3.38 and 2.09, P=0.001 and 0.037). The DL at water swallowing was shorter than those at semisolid swallowing and solid swallowing ((8.5±1.8) s vs. (9.8±2.2) and (10.6±2.8) s), and the DL at semisolid swallowing was shorter than that at solid swallowing, and the differences were statistically significant ( t=-10.21, -13.91 and -4.68, all P<0.001). The UES residual pressure at water swallowing was higher than those at semisolid swallowing and solid swallowing (9.5 mmHg, 6.5 to 12.3 mmHg vs. 8.0 mmHg, 4.5 to 11.7 mmHg and 5.5 mmHg, 2.0 to 9.3 mmHg), and the UES residual pressure at semisolid swallowing was higher than that at solid swallowing, and the differences were statistically significant ( t=3.48, 10.30 and 6.35, all P<0.001). Conclusions:The normal values of water-perfused HREM (GAP-36A) in Chinese population at resting period, water swallowing, semisolid swallowing and solid swallowing can provide a reference basis for clinical diagnosis and treatment for patients receiving water-perfused HREM examination.

ABSTRACT

Objective:To investigate the clinical characteristics and pregnancy outcomes in pregnant women with left ventricular non-compaction (LVNC).Methods:The clinical data of seven pregnant women with LVNC from January 2011 to December 2021 in Beijing Anzhen Hospital,Capital Medical University were retrospectively analyzed, including age, gestational age of symptom first occured, LVNC history, clinical symptoms, New York Heart Association (NYHA) cardiac function class, echocardiography, blood brain natriuretic peptide (BNP), treatment and the maternal and fetal outcomes.Results:Five cases were diagnosed before pregnancy, of which there were three women with medication; one case diagnosed in the month of pregnancy; one case diagnosed at 36 weeks of gestation. NYHA cardiac function was grade Ⅰ in four cases and grade Ⅱ in three cases before or during the first trimester of pregnancy. Of the five pregnant women who underwent echocardiography, there were one case of left ventricular insufficiency, three cases of mild left ventricular dysfunction and one case of normal left ventricular function before or during the first trimester of pregnancy. Of the five pregnant women to the second and third trimester of pregnancy, there were one case of grade Ⅳ, one case of grade Ⅲ, two cases of grade Ⅱ-Ⅲ and one case of grade Ⅱ in NYHA class ; three cases of left ventricular insufficiency, two cases of normal left ventricular function by echocardiography four cases had cardiac symptoms at 15-24 weeks of gestation and were treated with medication. In four cases, blood BNP increased to 214-1 197 ng/L during pregnancy, and were 89-106 ng/L after termination of pregnancy. There were 4 cases with arrhythmia. Indications for termination of pregnancy: LVNC complicated with heart failure in two cases, LVNC complicated with decreased cardiac function and threatened preterm birth in one case, complicated with pregnancy at full term in two cases, LVNC complicated with severe pulmonary hypertension in one case, and left ventricular dysfunction in one case. Cesarean section in four cases in the third-trimester, in one case in the second-trimester, and forceps curettage in two cases were taken. Two full-term infants,two preterm infants were born without LVNC.Conclusions:Women diagnosed with LVNC and low left ventricular ejection fraction before pregnancy are more prone to decreased cardiac function during pregnancy. Carrying out pregnancy risk assessment and strengthening the multi-disciplinary team management of high risk factors in pregnancy are conducive to achieve good pregnancy outcomes.

ABSTRACT

Objective:To analyze the expression of glial fibrillary acidic protein (GFAP) and neuronal nuclei (NeuN) antigen in hippocampus based on the depression model of juvenile rats caused by chronic unpredictable stress (CUS), and to explore the effect of electroacupuncture vagus nerve on CUS depression model.Methods:Six juvenile SD rats were selected as the control group (without any stimulation), and the rest were divided into CUS group, pseudo stimulation group, fluoxetine group and electroacupuncture group by random number method after CUS modeling, with 6 rats in each group. Fluoxetine group was given 10 mg/kg fluoxetine intervention; control group and CUS group were given the same amount of normal saline intervention; In the electroacupuncture group, the distal vagus nerve was stimulated after ligation, while in the pseudo stimulation group, only vagus nerve was isolated without electrical stimulation. After 28 d of intervention, the five groups were subjected to Open-field Test and Sucrose Preference Test. Hippocampal neurons were detected by hematoxylin and eosin (HE) staining, and the expressions of GFAP and NeuN in hippocampal were detected by immunohistochemistry.Results:After CUS modeling and before intervention, the number of vertical and horizontal movements, sucrose consumption and sucrose preference in CUS group, pseudo stimulation group, fluoxetine group and electroacupuncture group were significantly lower than those in the control group (all P<0.01); After the intervention, the above indexes in CUS group and pseudo stimulation group were still lower than those in the control group (all P<0.01), but the above indexes in fluoxetine group and electroacupuncture group were significantly higher than those in CUS group and pseudo stimulation group (all P<0.01). HE staining showed that the arrangement of hippocampal neurons in CUS group and pseudo stimulation group were loose, and there were cell swelling and pyknosis, which was significantly improved in fluoxetine group and electroacupuncture group. Immunohistochemical results showed that compared with the control group, the expression of GFAP increased and NeuN decreased in the hippocampus of CUS group and pseudo stimulation group (all P<0.01); Compared with CUS group and pseudo stimulation group, the expression of GFAP decreased and NeuN increased in fluoxetine group and electroacupuncture group (all P<0.01). Conclusions:Electroacupuncture of vagus nerve can obviously improve the depression symptoms of juvenile rats, which is similar to fluoxetine, and may be related to regulating the expression of GFAP and Neun in hippocampus.

ABSTRACT

Objective To evaluate the diagnostic efficiency of four anti-cysticercus IgG, IgG4 or IgM antibody test kits (enzyme-linked immunosorbent assay, ELISA) by different manufacturers, so as to provide insights into the epidemiological investigation and clinical detection of cysticercosis. Methods Forty serum samples from cerebral cysticercosis patients, 100 serum samples from healthy volunteers, 30 serum samples from paragonimiasis skrjabini patients, 17 serum samples from cystic echinococcosis and 19 serum samples from subcutaneous or cerebral sparganosis patients were collected and detected using anti-cysticercus IgG, IgG4 or IgM antibody test kits (brand A) and the anti-cysticercus IgG antibody test kit (brand B). The sensitivity, specificity and false negative rate of the four kits for detection of cysticercosis were estimated. Results The anti-cysticercus IgG, IgG4 or IgM antibody test kits (brand A) showed 95.00% (38/40), 87.50% (35/40), 7.50% (3/40) sensitivities and 98.00% (98/100), 100.00% (100/100) and 100.00% (100/100) for detection of cysticercosis, while the anti-cysticercus IgG antibody test kit (brand B) presented a 75.00% (30/40) sensitivity and 100.00% (100/100) specificity for detection of cysticercosis. The sensitivity for detection of cysticercosis was significantly higher by the anti-cysticercus IgG antibody test kit (brand A) than by the anti-cysticercus IgG antibody test kit (brand B) (χ2 = 6.28, P < 0.05); however, no significant difference was seen in the specificity by two kits (χ2 = 2.01, P > 0.05). The four ELISA kits showed overall false positive rates of 37.88% (25/66), 22.73% (15/66), 62.12% (41/66) and 15.15% (10/66) for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 37.61, P < 0.05), and the anti-cysticercus IgG antibody test kit (brand A) presented the highest overall false positive rate for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 7.56, P’ < 0.008), while a higher overall false positive rate was seen for detection of paragonimiasis, echinococcosis and sparganosis by the anti-cysticercus IgG antibody test kit (brand A) than by the anti-cysticercus IgG antibody test kit (brand B) (χ2 = 8.75, P’ < 0.008). The four ELISA kits showed false positive rates of 40.00% (12/30), 16.67% (5/30), 76.67% (23/30) and 13.33% (4/30) for detection of paragonimiasis (χ2 = 32.88, P < 0.05) and 21.05% (4/19), 26.32% (5/19), 73.68% (14/19) and 15.79% (3/19) for detection of sparganosis (χ2 = 19.97, P < 0.05), and the highest false positive rates were found by the anti-cysticercus IgM antibody test kit (brand A) for detection of paragonimiasis and sparganosis (all P’ < 0.008). However, the four ELISA kits showed comparable false positive rates of 52.94% (9/17), 29.41% (5/17), 23.53% (4/17) and 17.65% (3/17) for detection of echinococcosis (χ2 = 8.24, P > 0.05). In addition, the anti-cysticercus IgM anti-body test kit (brand A) showed false positive rates of 76.67% (23/30), 23.53% (4/17) and 73.68% (14/19) for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 14.537, P < 0.05), with the lowest false positive rate seen for detection of echinococcosis (χ2 = 14.537, P’ < 0.014), while no significant differences were seen in the false positive rate for detection of paragonimiasis, echinococcosis and sparganosis by other three ELISA kits (all P > 0.05). Conclusions The four anti-cysticercus IgG, IgG4 or IgM antibody test kits exhibit various efficiencies for serodiagnosis of cysticercosis. The anti-cysticercus IgG antibody test kit (brand A) has a high sensitivity for serodiagnosis of cysticercosis; however, it still needs to solve the problems of cross-reaction with other parasitic diseases and stability.

ABSTRACT

Curcuma kwangsiensis root tuber is a widely used genuine medicinal material in Guangxi, with the main active components of terpenoids and curcumins. It has the effects of promoting blood circulation to relieve pain, moving Qi to relieve depression, clearing heart and cooling blood, promoting gallbladder function and anti-icterus. Modern research has proved its functions in liver protection, anti-tumor, anti-oxidation, blood lipid reduction and immunosuppression. Considering the research progress of C. kwangsiensis root tubers and the core concept of quality marker(Q-marker), we predicted the Q-markers of C. kwangsiensis root tubers from plant phylogeny, chemical component specificity, traditional pharmacodynamic properties, new pharmacodynamic uses, chemical component measurability, processing methods, compatibility, and components migrating to blood. Curcumin, curcumol, curcumadiol, curcumenol, curdione, germacrone, and β-elemene may be the possible Q-markers. Based on the predicted Q-markers, the mechanisms of the liver-protecting and anti-tumor activities of C. kwangsiensis root tubers were analyzed. AKT1, IL6, EGFR, and STAT3 were identified as the key targets, and neuroactive ligand-receptor interaction signaling pathway, nitrogen metabolism pathway, cancer pathway, and hepatitis B pathway were the major involved pathways. This review provides a basis for the quality evaluation and product development of C. kwangsiensis root tubers and gives insights into the research on Chinese medicinal materials.

ABSTRACT

Objective:To analyze the clinical manifestations and esophageal motility characteristics of patients with gastroesophageal reflux disease (GERD) and extra-esophageal symptoms.Methods:From January 1 to October 30, 2018, at PLA Rocket Force Characteristic Medical Center, 180 hospitalized patients diagnosed with GERD and extra-esophageal symptoms were retrospectively analyzed. The patients were divided into laryngopharyngeal symptom group (65 cases), airway symptom group (58 cases) and mixed symptom group (57 cases). General data, clinical symptoms, gastroscopic manitestations, the results of high-resolution esophageal manometry and 24-hour multichannel intraluminal impedance and pH monitoring of each group were analyzed and compared. Chi-square test and one-way analysis of variance were used for statistical analysis.Results:The patients aged <40, 40 to 60 and >60 years accounted for 12.8% (23/180), 53.3% (96/180) and 33.9% (61/180), respectively, and the difference was statistically significant ( χ2=12.030, P=0.017). There were 18.9%(34/180) of patients without typical reflux symptoms. There were statistically significant differences in the incidence of ectopic esophagogastric mucosa or Barrett esophagus under gastroscopy between laryngopharyngeal symptom group, airway symptom group and mixed symptom group (21.5%, 14/65; 5.2%, 3/58 and 8.8%, 5/57, respectively) ( χ2=8.578, P=0.014). There were no statistically significant differences in the lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure or distal contractile integral between laryngopharyngeal symptom group, airway symptom group and mixed symptom group ((8.57±0.76), (8.87±0.79), and (10.51±0.97) mmHg (1 mmHg=0.133 kPa); (44.75±2.86), (42.81±4.06), and (39.14±3.20) mmHg; (506.13±64.30), (432.59±78.10), and (682.99±82.28) mmHg·s·cm)(all P>0.05). The DeMeester score of laryngopharyngeal symptom group , mixed symptom group and airway symptom group was (14.33±2.09), (21.94±5.30) and (30.47±5.85) points, respectively, and the difference was statistically significant ( F=3.226, P=0.043). The results of multi-channel impedance monitoring showed that acid reflux and weak acid reflux were the main reflux in the patients, which accounted for 55.5% (76/137) and 34.3% (47/137), respectively. Among 87.6% (120/137) of the patients, reflux mainly occurred in the upright position while 12.4% (17/137) of the patients had reflux in the supine position. Conclusions:The extra-esophageal symptoms of GERD is associated with age. Ectopic esophagogastric mucosa or Barrett esophagus are more common in GERD patients with laryngopharyngeal symptoms. There are more acid exposure and pathologic acid reflux in GERD mainly with airway symptoms. Weak acid reflux at upright position plays an important role in the reflux mechanism of GERD with extra-esophageal symptoms.

ABSTRACT

The most common metastatic site of prostate cancer is the bone, followed by the lung, bladder, liver, and adrenal gland. We report on a rare case of pancreatic metastasis from prostate cancer. A 52-year-old patient was admitted to the hospital with epigastric pain for 20 days. PET-CT showed malignant lesions in the prostate and pancreas, and prostate and pancreas puncture biopsies were performed, respectively. The patient was diagnosed as prostate cancer with pancreatic metastasis according to the pathological findings. After undergoing androgen deprivation therapy and docetaxel chemotherapy for 6 cycles, reexamination revealed that the pancreatic metastases had disappeared.

ABSTRACT

Objective To compare the changes of knowledge, attitude and practice (KAP) related to taeniasis and cysticercosis among primary school students before and after health education interventions in disease-elimination pilot areas of Henan Province, so as to evaluate the effectiveness of health education interventions. Methods A primary school was selected from each of Dushu, Bowang and Yangji townships, Fangcheng County, Henan Province from 2017 to 2019; then, 2 to 3 classes were randomly selected from grade 4 to 6 in each primary school, and finally, all students in these classes were enrolled as study subjects. A thematic health education lecture pertaining to taeniasis and cysticercosis was given once each year by means of “health education in class”. The KAP towards taeniasis and cysticercosis was investigated among primary school students using selffilled structured questionnaires, and the changes of awareness of taeniasis and cysticercosis control knowledge and percentage of healthy behaviors formation were compared in primary school students among years and following various frequencies of health education interventions. Results More than 10 thousand person-time primary school students received health education interventions during the period from 2017 to 2019, and a total of 1 223 person-time primary school students were investigated during the 3-year study period, including 633 person-time men and 590 person-time women and 88.55% of primary school students at ages of 10 to 12 years. The proportion of households raising pigs and using dry toiliets decreased from 5.30% (24/453) and 18.10% (82/453) in 2017 to 3.60% (13/361) and 11.08% (40/361) in 2019, respectively. The awareness rate of taeniasis and cysticercosis control knowledge increased significantly from 0.22% (1/453) in 2017 to 62.59% (256/409) in 2018 and 76.73% (277/361) in 2019 (χ2 = 567.60, P < 0.001), and the awareness rate was 85.25% (104/122) among primary school students attending the thematic special health education courses for successive three times. The awareness rates of taeniasis and cysticercosis control knowledge were 0.44% (1/225), 58.00% (116/200) and 71.63% (149/208) among male students and 0 (0/338), 66.99% (140/209) and 83.66% (128/153) among female students from 2017 to 2019, and there was a significant difference in the awareness of taeniasis and cysticercosis control knowledge between male and female students in 2019 (χ2 = 7.14, P = 0.01). On-site teaching by doctors was the students’ favorite way to receive health education interventions (70.07%, 857/1 223), followed by watching health education videos (58.63%, 717/1 223) and seeing parasite specimens (48.9%, 598/1 223). The proportion of students’ families who used cutting boards for raw and cooked food separately increased from 7.28% (33/453) in 2017 to 47.37% (171/361) in 2019, was 67.21% (82/122) among students attending the health education courses for successive three times. The proportion of students who frequently washed their hands before meals and after using toilet increased from 71.96% (324/453) in 2017 to 89.47% (319/361) in 2019 and was 95.90% (117/122) among students attending the health education courses for successive three times. In addition, the percentage of students washing hands frequently in families using dry toilets was significantly lower in those who did not use dry toilets (χ2 = 9.21, P = 0.002), and the proportion of students with a habit of eating raw or undercooked meat decreased significantly from 35.76% (162/453) in 2017 to 6.65% (24/361) in 2019 (χ2 = 69.11, P < 0.01). Conclusion The thematic health education activity of “health education in class” contributes greatly to the increase in the awareness of taeniasis and cysticercosis control knowledge and the rate of healthy behaviors formation among primary school students in diseaseelimination pilot areas of Henan Province.

ABSTRACT

The extract rates, multicomponent content and fingerprint were determined in this study to investigate the quality diffe-rence between standard decoction of raw Paeoniae Radix Alba and fried Paeoniae Radix Alba. UPLC fingerprint was established for 17 batches of standard decoction of raw and fried Paeoniae Radix Alba, and the contents of gallic acid, catechin, albiflorin, paeoniflorin and benzoyl paeoniflorin were determined. The peak areas of standard decoction were analyzed by the independent t-test and orthogonal partial least squares discriminant analysis. There was no significant difference in extract rates between the standard decoction of raw and fried Paeoniae Radix Alba. After fried processing, the content of albiflorin increased by 0.26%, while the contents of gallic acid, catechin, paeoniflorin and benzoyl paeoniflorin decreased by 13.04%, 27.97%, 10.30% and 18.79% respectively. There were 14 common peaks in the fingerprint of standard decoction of raw Paeoniae Radix Alba, and 16 common peaks in the fried Paeoniae Radix Alba. Peak 1 and peak 3 were new ones after processing, among which the peak 3 was 5-hydroxymethylfurfural. The results showed that peak 1, peak 3, peak 11 and peak 15 were the key compounds to distinguish standard decoction of raw and fried Paeoniae Radix Alba. In conclusion, this method is stable and can be used for the study of quantity transfer and quality control in the preparation process of standard decoction, granules and other dosage forms for raw and fried Paeoniae Radix Alba, providing reference for the identification of raw and fried Paeoniae Radix Alba and related preparations.

ABSTRACT

Objective:To analyze the clinical data of pregnant women complicated with cardiovascular disease in our center in the past 10 years, and to explore the trend of incidence, clinical diagnosis, and treatment of the disease.Methods:Clinical data of pregnant women with cardiovascular disease who delivered in Beijing Anzhen Hospital, Capital Medical University from 2010 to 2019 were collected and analyzed retrospectively. According to the time of the establishment of multidisciplinary team (MDT) in the center, the pregnant women were divided into the first 5-year group (2010-2014) and the second 5-year group (2015-2019). The general data, the composition of pregnancy complicated with cardiovascular disease and the changes of maternal and infant outcomes of the two groups were analyzed.Results:(1) During 2010-2019, there were 2 267 cases of pregnancy complicated with cardiovascular disease (836 cases in the first 5-year group and 1 431 cases in the second 5-year group), with a total incidence of 10.2% (2 267/22 334). Among all kinds of cardiovascular diseases, arrhythmia (41.0%, 930/2 267) and congenital heart disease (38.2%, 865/2 267) were more common. (2) There were 212 cases (25.4%, 212/836) and 426 cases (29.8%, 426/1 431) classified as Ⅲ or Ⅳ by modified WHO cardiovascular risk classification in the first 5-year group and the second 5-year group, respectively, and the difference was statistically significant ( χ2 =5.076, P=0.024). Among all kinds of cardiovascular diseases, there were 111 cases (13.3%, 111/836) and 159 cases (11.1%, 159/1 431) with valvular disease in the first 5-year group and the second 5-year group, respectively. The change of the component ratio was -16.5% (the difference was significant when the absolute value of change>10%), showing a significant decreasing trend. Aortic disease was found in 16 cases (1.9%, 16/836) and 56 cases (3.9%, 56/1 431), respectively, with a significant upward trend of 105.3%. (3) The mortality rate of pregnant women with cardiovascular disease was 1.0% (22/2 267), and 1.2% (10/836) and 0.8% (12/1 431) in the first 5-year grouop and the second 5-year group, respectively. There was no significant difference between the two groups ( χ2=0.702, P=0.402). ICU occupancy rates in the first 5-year group and the second 5-year group were 25.6% (214/836) and 20.7% (296/1 431), respectively, and the difference between the two groups was statistically significant ( χ2=7.306, P=0.007). There were no significant differences in cesarean section rate, mortality rate and incidence of adverse events between the two groups of pregnant women, and there were no significant differences in birth weight, preterm birth rate, mortality rate and asphyxia rate between the two groups of newborns (all P>0.05). Conclusions:Pregnancy complicated with cardiovascular disease is a common cause of adverse obstetric outcomes. There are various types of specific cardiovascular diseases, and the prognosis varies greatly. In recent years, the disease composition ratio has changed, and the severity and complexity of diseases have increased. Hierarchical management, MDT and individual management could improve the treatment level and reduce adverse outcomes.

ABSTRACT

Objective:To investigate the application value of esophagogastric anastomosis with double muscle flap plasty in total laparoscopic radical resection of proximal gastric cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 5 patients undergoing radical resection of proximal gastric cancer in Cancer Hospital of China Medical University from January to December 2020 were collected. All 5 cases were male, aged from 57 to 72 years, with a median age of 65 years. All 5 patients underwent total laparoscopic radical resection of proximal gastric cancer combined with esophagogastric anastomosis with double muscle flap plasty. Observation indicators: (1) operative situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect postoperative anastomosis, esophageal reflux, nutritional status, quality of life, tumor recurrence and metastasis of patients up to February 2021. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Operative situations: all 5 patients underwent surgery successfully. The operation time, time of esophagogastric anastomosis with double muscle flap plasty, number of lymph node dissected, volume of intraoperative blood loss, length of surgical incision of 5 patients were (316±41)minutes,(109±11)minutes, 26±4, (48±12)mL, (3.4±0.4)cm, respectively. Results of intraoperative rapid frozen section pathological examination showed negative of esophageal margin. (2) Postoperative situations: the time to postoperative initial flatus, time to postoperative initial food intake, during of postoperative hospital stay, cost of treat-ment of 5 patients were (4.8±1.5)days, (5.8±1.5)days, (11.6±2.1)days and (5.5±0.4)×10 4 yuan, respectively. Results of postoperative pathological examination of 5 patients showed gastric adeno-carcinoma in all 5 patients including 4 cases with moderately and poorly differentiated adeno-carcinoma and 1 case with highly differentiated adenocarcinoma, with the TNM staging of pT1a-3N0-1 M0 stage. Of the 5 patients, 1 case underwent postoperative mild pneumonia and was cured by conservative treatment such as anti-infection and promotion of sputum evacuation. (3) Follow-up: all 5 patients were followed up for 2 to 12 months, with a median follow-up time of 6 months. Of the 5 patients, 4 cases underwent anastomotic patency and 1 case underwent mild anastomotic stenosis who was improved after endoscopic treatment. None of the 5 patients underwent reflux esophagitis. The body mass index, the score of nutritional risk screening 2002, the score of patient-generated subjective global assessment and the score of tumor patient quality of life of 5 patients were 21 kg/m 2(range, 19-27 kg/m 2), 2(range, 1-2), 2(range, 1-3) and 47(range, 42-52), respectively. None of the 5 patients underwent tumor recurrence or metastasis. Conclusion:Esophagogastric anas-tomosis with double muscle flap plasty can be used in total laparoscopic radical resection of proximal gastric cancer which will lead to satisfactory short-term efficacy.

ABSTRACT

In recent years, with the change in life style, social environment, and national childbearing policy, the proportion of high-risk pregnant women has increased significantly, triggering the spectrum of obstetric diseases to constantly change, which has brought new challenges to the diagnosis and treatment of obstetrics. Traditional Chinese medicine (TCM) has been proved effective in dealing with a variety of obstetric diseases, and various treatment methods are available, which can serve as alternative means for solving refractory obstetric diseases. However, most obstetric clinicians are currently less aware of the therapeutic effects of TCM, which has significantly hindered its participation in clinical treatment. Therefore, the China Association of Chinese Medicine (CACM) organized the outstanding young obstetricians of TCM and western medicine to discuss 15 obstetric diseases responding specifically to TCM or integrated TCM and western medicine, including hyperemesis gravidarum, threatened abortion, ectopic gestation, cough during pregnancy, pregnancy-induced hypertension syndrome, maternal-fetal ABO incompatibility, postpartum hypogalactia, residual pregnancy tissue in uterine cavity, puerperal infection, pantalgia after childbirth, hematoma/undesirable healing after caesarean section, postpartum urinary retention, ileus after cesarean section, pelvic floor dysfunction, and postnatal depression. The suggestions for their treatment with TCM or integrated TCM and western medicine were also proposed, aiming to provide patients with effective and personalized treatments in clinical practice and improve the diagnosis and treatment effects of obstetric diseases, thus benefiting the public. At the same time, more obstetrical clinicians are expected to understand the therapeutic effects and advantages of TCM and draw on the strengths of both TCM and western, thereby promoting the establishment of an obstetric diagnosis and treatment system with Chinese characteristics.

ABSTRACT

Objective@#To investigate the potential value of 18F-fluorodeoxyglucose (FDG) PET/CT in predicting the survival of patients with primary tracheal malignant tumors. @*Materials and Methods@#An analysis of FDG PET/CT findings in 37 primary tracheal malignant tumor patients with a median follow-up period of 43.2 months (range, 10.8–143.2 months) was performed. Cox proportional hazards regression analyses were used to assess the associations between quantitative 18F-FDG PET/CT parameters, other clinic-pathological factors, and overall survival (OS). A risk prognosis model was established according to the independent prognostic factors identified on multivariate analysis. A survival curve determined by the Kaplan-Meier method was used to assess whether the prognosis prediction model could effectively stratify patients with different risks factors. @*Results@#The median survival time of the 37 patients with tracheal tumors was 38.0 months, with a 95% confidence interval of 10.8 to 65.2 months. The 3-year, 5-year and 10-year survival rate were 54.1%, 43.2%, and 16.2%, respectively. The metabolic tumor volume (MTV), total lesion glycolysis (TLG), maximum standardized uptake value, age, pathological type, extension categories, and lymph node stage were included in multivariate analyses. Multivariate analysis showed MTV (p = 0.011), TLG (p = 0.020), pathological type (p = 0.037), and extension categories (p = 0.038) were independent prognostic factors for OS. Additionally, assessment of the survival curve using the Kaplan-Meier method showed that our prognosis prediction model can effectively stratify patients with different risks factors (p 5.19, a TLG > 16.94 on PET/CT scans, squamous cell carcinoma, and non-E1 were more likely to have a reduced OS.

ABSTRACT

M701 is a bispecific CD3/EpCAM T-cell engager antibody for the treatment of malignant ascites. We developed a population pharmacokinetic/pharmacodynamic (PK/PD) model to quantitatively describe and predict the antitumor effect of M701 in human colorectal cancer xenograft mice. We developed the M701 PK model based on plasma concentration data after i.v. administration. A tumor growth model for human colorectal cancer xenograft was developed to evaluate the antitumor effect of M701. We additionally simulated the inhibitory effect of M701 on tumor volume under different dose regimens based on a PK/PD model. A two-compartment model was developed to predict the PK in human colorectal cancer xenograft mice. The relationship between the M701 concentration and tumor growth inhibition was characterized by a combined Simeoni tumor growth/transit compartment model. The estimated pharmacodynamic parameters were related to the tumor growth characteristics λ0 (0.212 d-1) and λ1 (0.044 7 cm3·d-1), to the drug potency k2 (0.071 5 mL·ng-1·d-1), and to the kinetics of tumor cell death k1 (2×10-5 d-1). A model visual predictive check showed that both the PK model and the tumor growth model closely fit the observed data. Simulated tumor growth after administration of M701 (0.5 mg·kg-1 every 6 days and 0.25 mg·kg-1 every 3 days) could be effectively inhibited. This population PK/PD model of M701 provides insight into the antitumor effect of M701 and supports the further therapeutic development of M701.

ABSTRACT

Objective: Traditional Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy can greatly decrease the anastomosis-related complications and reduce the incidence of reflux esophagitis, but its complexity limits the wide application. To decrease the complexity of Kamikawa anastomosis, the surgical team of Changzhi People's Hospital of Shanxi Changzhi Medical College improved this technique by using novel notion and reduced surgical procedures. This study aims to evaluate the efficacy and safety of modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy. Methods: A descriptive cohort study was carried out. Case enrollment criteria: (1) upper gastric carcinoma or esophagogastric junction carcinoma without distant metastasis was confirmed by preoperative gastroscopic biopsy and imaging examination; (2) tumor diameter was less than 4 cm; (3) preoperative clinical staging was cT1-3N1M0. Exclusion criteria: (1) patients received preoperative neoadjuvant chemotherapy; (2) patients had severe heart or lung disease, or poor nutritional status so that they could not tolerate surgery. Clinical data of 25 patients with upper gastric carcinoma or esophagogastric junction carcinoma who underwent modified Kamikawa anastomosis in digestive tract reconstruction in Heji Hospital (8 cases) and Changzhi People's Hospital (17 cases) from April 2019 to December 2020 were retrospectively collected. Of 25 patients, 21 were male and 4 were female, with mean age of 63.0 (49 to 78) years; 3 underwent open surgery and 22 underwent laparoscopic surgery. The modified Kamikawa anastomosis was as follows: (1) the novel notion of total mesangial resection of the esophagogastric junction was applied to facilitate the thorough removal of lymph nodes and facilitate hand-sewn anastomosis and embedding; (2) the diameter of the anastomotic stoma was selected according to the diameter of the esophageal stump, between 2.5 and 3.5 cm, to reduce the occurrence of anastomotic stenosis; (3) an ultrasonic scalpel was used to incise the esophageal stump, which could not only prevent bleeding of the esophageal stump, but also closely seal the esophageal mucosa, muscle layer and serosa to prevent esophageal mucosa retraction; (4) barbed suture was used to suture the remnant stomach fundus and esophagus to fix the stomach fundus in order to reduce the cumbersome and difficult intermittent sutures in a small space; (5) two barbed sutures were used to continuously suture the front and back walls of the anastomosis and complete the suture and fixation of the muscle flap. Relevant indicators of surgical safety, postoperative complications (using the Clavien-Dindo classification), esophageal reflux symptoms and the occurrence of esophagitis (using Los Angeles classification) were analyzed. The gastroesophageal reflux disease (GERD) score, gastroscopy, multi-position digestive tract radiography during postoperative follow-up were used to evaluate the residual gastric motility and anti-reflux efficacy. Results: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy was successfully performed in 25 patients. The surgical time was (5.8±1.8) hours, the intraoperative blood loss was (89.2±11.8) ml, and the average hospital stay was (13.8±2.9) days. Three cases (12.0%) developed postoperative anastomotic stenosis as Clavien-Dindo grade III and were healed after endoscopic dilation treatment. Postoperative upper gastrointestinal radiography showed 1 case (4.0%) with reflux symptoms as Clavien-Dindo grade I. Gastroscopy showed no signs of reflux esophagitis, and its Los Angeles classification was A grade. No anastomotic bleeding, local infection and death were found in all the patients. At postoperative 6-month of follow-up, GERD score showed no significant difference compared to pre-operation (2.7±0.6 vs. 2.4±1.0, t=-1.495, P=0.148). Conclusion: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy is safe and feasible with good anti-reflux efficacy.
