ABSTRACT

Ginkgo biloba Extract( GBE50) Dispersible Tablets is a new standardized prescription,which is widely used in the treatment of ischemic cardiovascular and cerebrovascular diseases. However,there are still many problems in its clinical application.Rational and safe use of GBE50 Dispersible Tablets is pivotal to the medication safety and clinical prognosis of patients. This consensus has been jointly formulated by clinical experts of traditional Chinese medicine and western medicine in cardiovascular and cerebrovascular diseases and followed the Manual for the Clinical Experts Consensus of Chinese Patent Medicine published by the China Association of Chinese Medicine. The present study identified clinical problems based on clinical investigation,searched the research papers according to PICO clinical problems,carried out evidence evaluation,classification,and recommendation by GRADE system,and reached the expert consensus with nominal group technique. The consensus combines evidence with expert experience. Sufficient evidence of clinical problems corresponds to " recommendations",while insufficient evidence to " suggestions". Safety issues of GBE50 Dispersible Tablets,such as indications,usage and dosage,and medication for special populations,are defined to improve clinical efficacy,promote rational medication,and reduce drug risks. This consensus needs to be revised based on emerging clinical issues and evidencebased updates in practical applications in the future.

ABSTRACT

Abstract Objectives: To investigate the diagnostic performance of single-source dual-energy computed tomography (DECT) based on gemstone spectral imaging technology (including Discovery CT750HD and Revolution CT) in patients with suspected feet/ankles gouty arthritis, and evaluate the urate deposition with a novel semi-quantitative DECT scoring system. Methods: A total of 196 patients were consecutively included. Feet and ankles were evaluated in all patients by single-source DECT scan. The 2015 EULAR/ACR criteria were used as the reference for the diagnosis of gout. The sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) of DECT for the diagnosis of gout in the early (≤1 year), middle (1-3 years), and late (> 3 years) disease durations were calculated. Besides, a novel semi-quantitative DECT scoring system was assessed for the measurement of urate deposition, and the correlation between the scores and the clinical and serological data were also evaluated. Moreover, the influences of artifacts on the diagnostic performance of DECT were also determined. Results: The sensitivity, specificity, and AUC of DECT in 196 patients were 38.10, 96.43%, and 0.673 in the early-stage group; 62.96, 100.00%, and 0.815 in the middle-stage group; and 77.55, 87.50%, and 0.825 in the late-stage group, respectively. The overall diagnostic accuracies in the AUC of DECT (Discovery CT750HD and Revolution CT) in the middle and late stages of gout were higher than that in the early stage of gout. Besides, the monosodium urate crystals were deposited on the first metatarsophalangeal joints and ankles/midfeet. Age, the presence of tophus, bone erosion, and disease duration considerably affected the total urate score. No statistical difference in the positive detection of nail artifact, skin artifact, vascular calcification, and noise artifact was found between the case and control groups. Conclusion: DECT (Discovery CT750HD and Revolution CT) showed promising diagnostic accuracy for the detection of urate crystal deposition in gout but had limited diagnostic sensitivity for short-stage gout. Longer disease duration, the presence of tophus, and bone erosion were associated with the urate crystal score system. The artifacts do not remarkably affect the diagnostic performance of DECT in gout.

ABSTRACT

Objective:To analyze the evolutionary characteristics and variations of 2019 novel coronavirus (2019-nCoV) strains imported from abroad in Henan Province.Methods:A total of 16 imported cases of coronavirus disease 2019 (COVID-19) reported in Henan Province from May to December 2020 were enrolled. The throat swab specimens from the patients were collected and sent to the Henan Provincial Center for Disease Control and Prevention for whole genome sequencing. Taking SARS-CoV-2 Wuhan-Hu-1 published in Global Initiative on Sharing All Influenza Data (GISAID) as the reference sequence, the sequences were aligned and analyzed by MEGA X, and the phylogenetic tree was constructed by the maximum likelihood method.Results:Among 16 cases, 13 cases were imported from Russia, two cases were imported from Myanmar, and one case was imported from Ukraine. A total of 16 strains of 2019-nCoV genomes with the lengths of 29 804 bp to 29 882 bp were obtained. A total of 145 nucleotide mutations and 80 amino acid mutations were detected. Nucleotide variations of C241T, C3037T, C14408T, A23403G and the amino acid variation of D614G in spike protein were detected in all sequences. Meanwhile, insertion A at the site of 29704 was found in BetaCov/HEN02/Human/2020, BetaCov/HEN04/Human/2020 and BetaCov/HEN05/Human/2020. Deletion variation was not found. Phylogenetic analysis showed that there was no correlation between the 16 strains and currently epidemic variants of concern (VOC) .Conclusion:From May to December 2020, the detection of viral genome mutations in the imported cases of Henan Province shows randomness and diversity, while the strains are not VOC.

ABSTRACT

To systematically evaluate the efficacy and safety of traditional Chinese medicine in treating patients with resistant hypertension. CNKI, Wanfang, VIP, CBM, PubMed, Web of Science, Cochrane Library, EMbase and other databases were retrieved by computers to screen out the randomized controlled trial of traditional Chinese medicine in treating resistant hypertension. Cochrane Handbook was used to evaluate the quality of the included literature, RevMan 5.3 and Stata 12.0 was used for Meta-analysis. Finally, 11 literatures meeting the criteria were included, involving 1 023 patients. The results of Meta-analysis showed that the combined therapy of standard triple antihypertensive regimen with traditional Chinese medicine could further reduce systolic blood pressure of patients with resistant hypertension(MD=-16.69, 95%CI[-22.21,-11.16], P<0.000 01), reduce diastolic blood pressure(MD=-7.51, 95%CI[-8.26,-6.76], P<0.000 01), improve the effective rate of anti-hypertension(OR=5.16, 95%CI[3.01, 8.84], P<0.000 01), improve the up-to-standard rate of blood pressure(OR=3.01, 95%CI[1.49, 6.09], P=0.002), and improve the effectiveness of clinical symptoms(OR=4.48, 95%CI[2.31, 8.68], P<0.000 01), with no significant effect on creatinine level(MD=-2.51, 95%CI[-6.91, 1.89], P=0.26). The results of this study indicated that the combined therapy of standard triple antihypertensive regimen with traditional Chinese medicine could further improve the clinical efficacy in patients with resistant hypertension with a good safety, but more high-quality clinical studies are still needed to verify this conclusion.

ABSTRACT

Liver cancer has always been a threat to national health since liver disease has a high incidence rate in China. At present, methods for the prevention and treatment of liver cancer have unsatisfactory effects in clinical practice, and with in-depth studies, scholars have changed their focus to cancer-associated fibroblasts (CAFs) in tumor microenvironment. More and more evidence has shown that CAFs may provide a new target for the prevention and treatment of liver cancer. This article summarizes the role of CAFs in the development and progression of liver cancer and the potential of CAFs in the treatment of liver cancer.

ABSTRACT

BACKGROUND@#Despite improvements in disease diagnosis, treatment, and prognosis, breast cancer is still a leading cause of cancer death for women. Compelling evidence suggests that targeting cancer stem cells (CSCs) have a crucial impact on overcoming the current shortcomings of chemotherapy and radiotherapy. In the present study, we aimed to study the effects of T cells and a critical anti-tumor cytokine, interferon-gamma (IFN-γ), on breast cancer stem cells.@*METHODS@#BALB/c mice and BALB/c nude mice were subcutaneously injected with 4T1 tumor cells. Tumor growth and pulmonary metastasis were assessed. ALDEFLOUR™ assays were performed to identify aldehyde dehydrogenasebright (ALDHbr) tumor cells. ALDHbr cells as well as T cells from tumor-bearing BALB/c mice were analyzed using flow cytometry. The effects of CD8+ T cells on ALDHbr tumor cells were assessed in vitro and in vivo. The expression profiles of ALDHbr and ALDHdim 4T1 tumor cells were determined. The levels of plasma IFN-γ were measured by enzyme-linked immunosorbent assay, and their associations with the percentages of ALDHbr tumor cells were evaluated. The effects of IFN-γ on ALDH expression and the malignancy of 4T1 tumor cells were analyzed in vitro.@*RESULTS@#There were fewer metastatic nodules in tumor-bearing BALB/c mice than those in tumor-bearing BALB/c nude mice (25.40 vs. 54.67, P < 0.050). CD8+ T cells decreased the percentages of ALDHbr 4T1 tumor cells in vitro (control vs. effector to target ratio of 1:1, 10.15% vs. 5.76%, P < 0.050) and in vivo (control vs. CD8+ T cell depletion, 10.15% vs. 21.75%, P < 0.001). The functions of upregulated genes in ALDHbr 4T1 tumor cells were enriched in the pathway of response to IFN-γ. The levels of plasma IFN-γ decreased gradually in tumor-bearing BALB/c mice, while the percentages of ALDHbr tumor cells in primary tumors increased. IFN-γ at a concentration of 26.68 ng/mL decreased the percentages of ALDHbr 4T1 tumor cells (22.88% vs. 9.88%, P < 0.050) and the protein levels of aldehyde dehydrogenase 1 family member A1 in 4T1 tumor cells (0.86 vs. 0.49, P < 0.050) and inhibited the abilities of sphere formation (sphere diameter <200 μm, 159.50 vs. 72.0; ≥200 μm, 127.0 vs. 59.0; both P < 0.050) and invasion (89.67 vs. 67.67, P < 0.001) of 4T1 tumor cells.@*CONCLUSION@#CD8+ T cells and IFN-γ decreased CSC numbers in a 4T1 mouse model of breast cancer. The application of IFN-γ may be a potential strategy for reducing CSCs in breast cancer.

ABSTRACT

Objective:To monitor the changes in specific IgM and IgG antibodies in patients diagnosed with COVID-19 after SARS-CoV-2 infection, and analyze their clinical significance.Methods:A total of 168 serum samples were collected from 56 COVID-19 patients with different disease courses who were positive for nucleic acid test at Henan Center for Disease Control and Prevention on January 8, 2020 and February 21, 2020. Serum samples from 25 healthy people excluded from COVID-19 were used as control group. IgM and IgG antibodies against SARS-CoV-2 were detected by chemiluminescence method.Results:IgM antibody increased sharply in 1-3 weeks after onset, and reached the peak value (21.78 AU/ml) in the 3rd week after onset. IgG antibody increased the most in 3-6 weeks after onset, and reached the peak value (81.58 AU/ml) in the 9th week after onset. The levels of IgM and IgG antibodies were closely correlated with age and disease course ( P<0.05). The antibody level of 30-60 years old group was the highest, the IgM antibody positive rate and antibody level of acute stage and previous infection were lower than that of recovery stage, and the IgG antibody positive rate and antibody level of acute stage were lower than that of recovery stage and previous infection. During the whole course of the disease, the levels of IgM and IgG antibodies increased gradually in the acute stage, reached the peak in the recovery stage, and decreased and maintained at a certain level in the past infection. Conclusions:Serum SARS-CoV-2 IgM and IgG antibody detection can be used as auxiliary diagnostic indicators for COVID-19, and its continuous observation is helpful for epidemiological investigation, serological diagnosis and disease course monitoring.

ABSTRACT

Objective To study the epidemic characteristics of hand foot mouth disease (HFMD) and the influence of meteorological factors on the incidence of HFMD in Beijing from 2010 to 2019, and to provide scientific evidence for the warning, prediction, prevention and control of HFMD. Methods Descriptive statistical analysis was conducted to analyze the epidemic characteristics of HFMD in Beijing from 2010 to 2019 using R4.0.2 software, and the relationship between meteorological factors such as daily average temperature, daily average relative humidity, daily average precipitation, daily average air pressure, and daily average wind speed and HFMD incidence from 2015 to 2019 was analyzed by using distribution lag nonlinear model. Results In 2010-2019, a total of 324 864 HFMD cases were reported in Beijing, with an average incidence rate of 155.10/100,000. May to July was the annual peak of HFMD. The average daily temperature, relative humidity and precipitation were positively correlated with the incidence of HFMD (Rs=0.66, 0.45 and 0.24, P=0.0000, 0.0000 and 0.0000, respectively). The average daily wind speed and pressure were negatively correlated with the incidence of HFMD (Rs=-0.14 and -0.3, P=2.22×10-9 and 0.0000, respectively). The RR was the highest when the air temperature was 25℃ and at the lag of 10 day, which was 1.41 (95%CI:1.12-1.77). Humid weather conditions were the risk factors of HFMD, and the influence time was relatively long. The RR was the highest when the relative humidity was 84.5% and the lag was 15 days, which was 1.51 (95%CI:1.34-1.70). When daily average wind speed was 3m/s, and the lag was 14 days, the RR was the highest, which was 1.22 (95%CI:0.86-1.73). The RR was the highest when the daily average pressure was 842.5 hPa and the lag was 5 day, which was 1.20 (95%CI:0.66-2.07). When the daily average precipitation was 166.5 mm and the lag was 7 days, the RR was the highest, which was 4.37 (95%CI:1.61-11.84). When the above meteorological conditions were met, the risk of HFMD was the highest. Conclusion Meteorological factors such as daily average temperature, daily average relative humidity, daily average precipitation, daily average pressure and daily average wind speed are closely related to the incidence of HFMD, which is nonlinear and has certain lag. It can be used to predict the risk and epidemic intensity of HFMD, and to provide a scientific basis for the prevention and control, early warning, and prediction of infectious diseases.

ABSTRACT

Objective:To construct an intelligent performance measurement system of gastrointestinal endoscopy and to analyze its value for endoscopic quality improvement.Methods:The intelligent gastrointestinal endoscopy performance measurement system was developed by using the deep convolutional neural network (DCNN) and deep reinforcement learning, based on the Digital Imaging and Communications in Medicine. Images were acquired of patients undergoing gastrointestinal endoscopy at Digestive Endoscopy Center of Renmin Hospital of Wuhan University from December 2016 to October 2018. The system applied cecum recognition model (DCNN1), images in vitro and in vivo recognition model (DCNN2), and identification model at 26 gastric sites (DCNN3) to monitor indices such as cecal intubation rate, colonoscopic withdrawal time, gastroscopic inspection time, and gastroscopic coverage. Images of 83 gastroscopies and 205 colonoscopies acquired at Digestive Endoscopy Center of Renmin Hospital of Wuhan University from March to November 2019 were randomly selected to examine the effectiveness of the system. Results:The intelligent gastrointestinal endoscopy performance measurement system consisted of quality analysis of both gastroscopy and colonoscopy, including all indices, and could be generated automatically at any time. The accuracy for cecal intubation rate, colonoscopic withdrawal time, gastroscopic inspection time, and gastroscopic coverage were 92.5% (172/186), 91.7% (188/205), 100.0% (83/83), 89.3% (1 928/2 158), respectively.Conclusion:The intelligent performance measurement system for gastrointestinal endoscopy can be recommended for the quality control of gastrointestinal endoscopy, from which endoscopists can get feedback and improve the quality of gastrointestinal endoscopy.

ABSTRACT

Objective:To evaluate the 5-year survival outcome of patients with unresectable locally advanced non-small cell lung cancer (NSCLC) treated with Endostar in combination with platinum-based concurrent chemoradiotherapy.Methods:From March 2009 to June 2015, 115 patients with the unresectable locally advanced NSCLC from two prospective studies[Clinical trials 2009-2012(ClinicalTrials.gov NCT01894) and 2012-2015(ClinicalTrials.gov, NCT01733589)] were treated with Endostar in combination with platinum-based concurrent chemoradiotherapy. A total dose of 60-66 Gy was delivered in 30-33 fractions. Endostar was given 1 week prior to the beginning of radiotherapy, and repeated fortnightly during the concurrent chemoradiotherapy. After long-term follow up, survival outcome was evaluated in 104 patients treated with radiation dose of ≥60 Gy. Kaplan-Meier method was used for survival analysis. Univariate survival analysis was performed using the log-rank test.Results:Of 104 eligible patients, 60.6% of them had squamous carcinoma and 65.4% were classified in stage Ⅲ B. All the patients received ≥2 cycles of Endostar and 93.3% of them received 4 cycles of Endostar. The median follow-up time was 68.3 months. The median overall survival (OS) and median progression-free survival (PFS) were 31.3 and 13.9 months, respectively. The 3-year and 5-year OS were 45.6% and 35.7%, respectively. The 3-year and 5-year PFS were 27.1% and 24.9%, respectively. Univariate analysis indicated that sex, ECOG, pathological type, clinical stage, radiotherapy technique, chemotherapy regimen, chemotherapy cycle and cycle of Endostar use were not associated with OS. Late radiation injury occurred in 14.4% of patients, and no grade 4-5 late injury was observed. Conclusion:Patients with unresectable locally advanced NSCLC treated with Endostar fortnightly in combination with platinum-based concurrent chemoradiotherapy achieve better OS than historical data with tolerable toxicities.

ABSTRACT

Context: Better management strategies are needed to improve the survival of patients with hilar cholangiocarcinoma (HCCA). Aims: This study was designed to examine the effects of different treatment methods on survival and prognostic factors in HCCA. Settings and Design: We retrospectively analyzed the clinical data of 354 patients with HCCA treated at our institution from 2003 to 2013. Materials and Methods: Patients were divided into three groups according to the treatment: the radical resection group, the nonradical resection group, and the biliary drainage-only group. Statistical Analysis Used: The Kaplan–Meier method was used to compare survival rates between the groups, and the independent prognostic factors were assessed using the Cox proportional hazards model. Results: There were 110 patients in the radical resection group, 93 patients in the nonradical resection group, and 151 patients in the biliary drainage-only group, and they showed differing survival rates: 1-year survival rates of 70.7%, 49.5%, and 31.3%; 2-year survival rates of 62.9%, 24.7%, and 9.0%; 3-year survival rates of 34.7%, 4.0%, and 0%; and median survival of 21.7 months, 13.6 months, and 8.7 months, respectively. The radical resection group had the longest overall survival (P< 0.001). Treatment method, albumin (ALB), total bilirubin (TBIL), postoperative pathological T-stage, and distant metastasis were identified as independent prognostic indicators of survival. Conclusions: Radical resection significantly increases survival in patients with HCCA, and an increase in ALB and a decrease in TBIL improve the prognosis of patients with HCCA

ABSTRACT

The aim of this paper was to study the role of phosphoinositide 3-kinase(PI3 K), protein kinase B(Akt) and mamma-lian target of rapamycin(mTOR) in the inhibition of premature ovarian failure induced by D-galactose(D-gal) in mice model by ginsenoside Rg_1(Rg_1). Fifty-four female SPF BALB/c mice were randomly divided into PBS group, D-gal group, and Rg_1 group. In the D-gal group, D-galactose(200 mg·kg~(-1)·d~(-1)) was injected subcutaneously into the neck and back for 42 days. In the PBS group, an equal amount of phosphate buffered saline(PBS) was injected into the neck and back for 42 days. In addition to the therapy of D-gal group, Rg_1 group was given Rg_1(20 mg·kg~(-1)·d~(-1)) through intraperitoneal injection since the 15 th day for 28 days, at the same time, the D-gal group and the PBS group were also given an equal amount of PBS through intraperitoneal injection since the 15 th day for 28 days. After the treatment, the estrous cycle changes of the mice were detected, and the ovarian SA-β-Gal staining was used to detect the changes of ovarian aging. Western blot was used to detect the changes in protein expressions of PI3 K, Akt, mTOR, S6 k, LC3-Ⅱ and P16~(INK4 a). Fluorescence quantitative PCR was used to detect the changes in mRNA expressions of PI3 K, Akt, mTOR, S6 k, LC3-Ⅱ and P16~(INK4 a). According to the findings, compared with the PBS group, the D-gal group began to show estrous cycle disorder in the 3 rd week,the ovarian SA-β-Gal staining positive granulosa cells increased in the D-gal group, the expression of senescence marker P16~(INK4 a) increased, while the expression of autophagy signaling molecule LC3-Ⅱ decreased. After treatment with Rg_1, the positive rate of ovarian SA-β-Gal staining in Rg_1 group decreased, the expression level of autophagy signaling molecule LC3-Ⅱ in Rg_1 group was higher than that in D-gal group, while the expression level of senescence marker P16~(INK4 a) was lower than that in D-gal group. Compared with the PBS group, the protein and mRNA expressions of PI3 K, Akt, mTOR and S6 k in the D-gal group were up-regulated, the protein expressions of Akt, mTOR and S6 k in the Rg_1 group were up-regulated, and the mRNA expressions of PI3 K and mTOR were up-regulated. After treatment with Rg_1, the protein expressions of PI3 K, Akt, mTOR and S6 k in the Rg_1 group were lower than those in the D-gal group, while the mRNA expressions of Akt, mTOR and S6 k in the Rg_1 group were lower than those in the D-gal group. The finding ssuggested that Rg_1 has the effect in delaying ovarian premature failure in D-gal-induced mouse models, and PI3 K/Akt/mTOR autophagy signaling pathways play an important role.

ABSTRACT

Objective Serum total prostatic specific antigen (tPSA), free prostatic specific antigen (fPSA), fPSA/tPSA ratio, and prostate cancer-specific antigen density (PSAD) were determined to explore the best identification point, thus improving the specificity of early screening of prostate cancer. Methods The tPSA, fPSA, fPSA/tPSA, and PSAD of patients with benign prostatic hyperplasia group (n=250) and prostate cancer group (n=92) were tested, and the receiver operating characteristic (ROC) curve was drawn to determine the best cutoff value for the evaluation. Results When the cutoff values of tPSA, fPSA/tPSA, and PSAD were at 11.3 mg/L, 0.16, and 0.18 mg/(L·cm3), respectively, the specificity and sensitivity were the best:82.4% and 84.2% for tPSA, 76.9% and 81.7% for fPSA/tPSA, and 83.1% and 80.4% for PSAD.When the best cutoff values of tPSA, fPSA/tPSA, and PSAD were combined in analysis, the specificity and sensitivity of fPSA/tPSA and PSAD combination showed the best result (92.4% and 81.4%, respectively).When the tPSA value was in the range of 4-10 mg/L, the optimal cutoff values of PSAD and fPSA/tPSA were 0.21 mg/(L·cm3) and 0.15, and the specificity and sensitivity reach the best, which were 84.1% and 80.1%, 81.0 % and 80.3%, respectively. Conclusion Combination of tPSA, fPSA/tPSA and PSAD analysis is better than any single of them in early screening of prostate cancer.The specificity and sensitivity of combined use of fPSA/tPSA and PSAD could serve as an optimal screening reference value.

ABSTRACT

Objective:To investigate the etiological characteristics and drug resistance of non-typhoid Salmonella isolated from stool samples of children under 5 years old with diarrhea in Henan Province. Methods:Intestinal bacteria were isolated from fecal samples of 4 250 diarrhea children under five years old in five monitoring sites in Henan Province from 2015 to 2018. Serotypes and drug sensitivity of Salmonella strains were analyzed. The annual change in drug resistance was analyzed by Chi-square test and all data were analyzed retrospectively. Results:The detection rate of non-typhoid Salmonella in fecal samples was 8.73% (371/4 250). The highest detection rate was in the 0-1 age group (51.75%) and the peak season for Salmonella infection was from May to October. The most common serotype was Salmonella enteritidis (36.93%), followed by 4, 5, 12: i: - Salmonella (14.82%) and Salmonella typhimurium (14.02%). The non-typhoid Salmonella isolates were resistant to ampicillin and sulfamethoxazole with drug resistance rates of more than 80%, but more sensitive to ceftazidime, cefepime and cefoxitin. There were significant differences in drug resistance to cefepime, levofloxacin, ciprofloxacin, amikacin, doxycycline, chloramphenicol and compound neoforman among the strains isolated in different years ( P<0.05). Multidrug-resistant strains accounted for 86.52%. Conclusions:There was diversity in the serotypes of non-typhoid Salmonella in diarrheal children under five years old in Henan Province. The predominant serotype was Salmonella enteritidis. Drug resistance to common antibiotics was detected in the isolates, and most of them were multidrug-resistant.

ABSTRACT

Objective:To evaluate the effect of patient-controlled intravenous analgesia (PCIA) with dexmedetomidine mixed with subanesthetic dose of ketamine on anxiety and depression in the patients with advanced cancer pain.Methods:Sixty patients of either gender with advanced cancer pain, aged 24-82 yr, with poor analgesic effect or obvious adverse reactions after three-step analgesic treatment, were selected and randomly divided into 2 groups ( n=30 each) using a random number table method: routine treatment group (group R) and dexmedetomidine mixed with ketamine group (group DK). The initial dose of morphine for PCIA was 1/3 of the oral dose in group R. In group DK, ketamine 5.4 mg/kg (90 μg·kg -1·h -1) and dexmedetomidine 6 μg/kg (0.1 μg·kg -1·h -1) were added on the basis of group R. Tropisetron 8 mg was added to analgesics and diluted to 200 ml with normal saline in both groups.The analgesic pump was programmed to deliver 4 ml with an initial dose of 4 ml, lockout interval of 15 min and background infusion at 4 ml/h.The numerical rating scale score, Ramsay sedation score, Chinese version of State-Trait Anxiety Inventory score and Beck Depression Inventory-Ⅱ score were recorded before PCIA and at 4, 12, 24 and 48 h of PCIA.The development of effective analgesia and satisfactory sedation, occurrence and degree of depression, score for patient's quality of life and satisfaction score, consumption of morphine and adverse reactions such as constipation, nausea and vomiting, agitation and respiratory depression were recorded within 48 h of PCIA. Results:Compared with group R, the NRS score was significantly decreased, the rate of effective analgesia was increased, Beck Depression Inventory-Ⅱscore and Chinese version of State-Trait Anxiety Inventory score were decreased, the incidence and degree of depression were decreased, incidence of nausea and vomiting and constipation, consumption of morphine and pressing times of PCIA pump were decreased, and the score for patient's quality of life and satisfaction score were increased in group DK ( P<0.05). Conclusion:PCIA with dexmedetomidine mixed with subanesthetic dose of ketamine can significantly enhance the analgesic effect, improve anxiety and depression, and raise the quality of life when used for the patients with advanced cancer pain.

ABSTRACT

Objective:To explore the expression and clinical significance of mucin 5B in patients with primary intrahepatic bile duct stones (PHL) after hepatectomy.Methods:Collected the bile duct mucosa of 48 patients with intrahepatic bile duct stones (PHL group) and 16 patients with non-calculous benign liver disease (control group) who underwent hepatectomy in the Third Affiliated Hospital of Wenzhou Medical University from January 2014 to January 2019, Bile duct wall, bile and venous blood. The preoperative bile and serum indexes of the two groups were compared. Immunohistochemical staining was used to examine the expression of mucin 1 and mucin 5B in the bile duct wall, and the bile duct wall was examined pathologically by HE routine staining. With mucin 1 as a positive control and β-actin as an internal reference gene, real-time PCR was used to examine the mRNA expression levels of mucin 1 and mucin 5B in the bile duct mucosa. Pearson correlation analysis was used to analyze the correlation of variables within the PHL group.Results:The preoperative serum lipid indexes in the PHL group were higher than those in the control group, while the total bile acid concentration [(181.5±18.2) mmol/L vs. (192.1±22.5) mmol/L] and the molar percentage of bile acid [(80.7±1.6)% vs. (89.7±1.0)%] is lower than the control group, the difference is statistically significant ( P<0.05). The expression of mucin 1 mRNA in the PHL group was higher than that in the control group, but the difference was not statistically significant ( P>0.05). The expression of mucin 5B mRNA in the PHL group was significantly higher than that in the control group [(0.94±0.12) vs. (0.73±0.24)], the difference was statistically significant ( P<0.05); The increased expression of bile duct mucin 5B mRNA was negatively correlated with the level of total bile acids in bile ( r=-0.4, P<0.05). Conclusions:The increased expression of mucin 5B is closely related to PHL, which may be related to the promotion of bile acid absorption by the bile duct mucosal epithelium, which causes mucin to secrete into the bile in large quantities, leading to the formation of stone-causing bile.

ABSTRACT

Objective:To analyze the feasibility of hippocampal-avoidance (HA) prophylactic cranial irradiation (PCI) in small cell lung cancer patients (SCLC)(limited stage) after chemotherapy and thoracic radiation.Methods:From June 2016 to March 2019, 40 eligible SCLC patients were recruited and randomly divided into the routine PCI ( n=22) and hippocampal-avoidance PCI (HA-PCI) groups ( n=18). The HA zone was contoured according to the criteria of RTOG 0933. Volumetric-modulated arc therapy (VMAT) was adopted in the HA-PCI group. After radiotherapy, Hopkins verbal learning test (HVLT) and MRI were performed. Results:The average hippocampus volume was (4.01±1.57) cm 3, the average HA volume was (20.13±4.14) cm 3, HA D 100% was (7.19±0.38) Gy and HA D max was (14.38±1.18) Gy. During HVLT, 1-month-after-PCI vs. before-PCI (trial3, trial4, learning, percent retained), 1-month-after-PCI vs. after-PCI (trial3, learning), HA-PCI cohort showed advantages over PCI in HVLT scores. The average follow-up time was (17.00±8.47) months. Two patients with brain metastases which were out of the HAZ received routine PCI. Conclusions:PCI using VMAT technology to protect hippocampus is feasible in dosimetry. The test results indicate that the protective effect of hippocampus protection on memory is worthy of further promotion in clinical practice.

ABSTRACT

Objective:To evaluate the clinical efficacy and safety of stereotactic body radiation therapy (SBRT) for stage Ⅰ-Ⅱ non-small cell lung cancer.Methods:Retrospective analysis of patients with early stage lung cancer who received SBRT in Zhejiang Cancer Hospital from 2012 to 2018 was conducted. The Kaplan-Meier method was used for survival analysis. The main endpoints of the study were locoregional control (LRC) and cancer specific survival (CSS).Results:A total of 142 eligible cases were included, with a median BED10100Gy (100-132Gy). The median age was 75.6 years (47.2-89.0 years), among which 75 patients were aged (greater than or equal to 75 years old). The median follow-up time was 31.0 months, for patients< 75 years old and patients ≥ 75 years old. The 5-year LRC were 84.5% and 95.8% respectively, 5-year CSS were 72.4% and 78.6% respectively, for patients< 75 years old and elderly patients. The systemic response was mild during treatment, no grade 4-5 adverse events occurred in all patients. The main acute side effect was radiation pneumonitis (RP) below grade 3. Grade 2 RP appeared in 14 patients (9.9%) after SBRT where grade 3 RP occurred in 2(1.4%). There was no treatment-related mortality in the SBRT group.Conclusions:SBRT is a safe and effective treatment for early primary lung cancer with satisfactory rates of LRC and CSS in 5 years and mild complication, which is similar to previous reports.

ABSTRACT

Objective:To study the effect of doctor-nurse cooperation responsibility system in medical care in patients with pulmonary thromboembolism.Methods:A total of 208 patients with suspected pulmonary thromboembolism were selected as research objects from Oct 1 st, 2017 to Oct 1 st, 2018. Among them, there were 144 patients with high risk pulmonarythromboembolism, 64 patients with diagnosed pulmonary thromboembolism. They were divided into control group and experimental group randomly by admission time, 104 patients for each group. Therein, there were 74 patients with high risk pulmonary thromboembolism, and 30 patients with diagnosed pulmonary thromboembolism in control group, 70 patients with high risk pulmonary thromboembolism, and 34 patients with diagnosed pulmonary thromboembolism in study group. The patients in control group were given conventional nursing management mode and patients in study group were given all-in-one nursing mode in medical care. The nursing effects were compared between the two groups. Results:The missing report rate in the control group was 8.1% (6/74), high risk identification leakage rate was 12.2% (9/74), the preventive drug treatment leakage rate was 8.1% (6/74), and the physical preventive leakage treatment rate was 9.5% (7/74). The experimental group about the missing report rate was 2.9% (2/70), high risk identification leakage rate was 4.3%(3/74), The preventive drug treatment leakage rate was 2.9% (2/70), physical preventive leakage treatment rate was 4.3% (3/70), all of these items were lower than those of the control group, and patient satisfaction of the high risk patients had significant differences between the two groups ( χ2 values were 6.08-7.51, P<0.05). And the inspection checklist leakage rate of the control group [43.3% (13/30)] was higher than that of the experimental group [17.6% (6/34)], the health education awareness rate of the control group was [36.7% (11/30)], lower than that of the experimental group [91.2%(31/34)], patient satisfaction of the control group [40.0% (12/30)] was lower than that of the experimental group [94.1% (32/34)], these items had significant differences between the two groups ( χ2 values were 10.26, 4.57, 4.22, P<0.05). Conclusions:Doctor-nurse cooperation responsibility system in medical care have improved the implementation rate of prevention and treatment intervention of pulmonary thromboembolism, and improve the health education awareness rate and satisfaction rate of patients. It makes the prevention and control management of pulmonary thromboembolism for patients more effectively.
