ABSTRACT

A novel pair of Z/E isomeric compounds with unprecedented carbon skeleton were isolated from an aqueous extract of Aspongopus chinensis Dallas by macroporous resin, silica gel, and semi-preparative high performance liquid chromatography (HPLC). Their structures were identified by nuclear magnetic resonance (NMR), Infrared spectroscopy (IR), Mass spectroscopy (MS) and other spectroscopic methods as (Z)-3-(but-1″-en-1″-yl)-1-(2ʹ-hydroxyethyl)-4-propylpyridin-1-ium, namely aspongopyridine A, and (E)-3-(but-1″-en-1″-yl)-1-(2ʹ-hydroxyethyl)-4-propylpyridin-1-ium, namely aspongopyridine B, respectively. Besides, the anti-inflammatory, anti-tumor, acetylcholinesterase inhibition and butyrylcholinesterase inhibition activities of the compounds 1 and 2 were evaluated. The results showed that compounds 1 and 2 have no anti-inflammatory, anti-tumor, and butyrylcholinesterase inhibition activities instead of weak acetylcholinesterase inhibition activity.

ABSTRACT

Xiaoruwan is one of the classic prescriptions included in the Catalogue of Ancient Classic Prescriptions (the Second Batch of Pediatrics) published by the National Administration of Traditional Chinese Medicine(TCM) in 2022 with definite clinical efficacy, but it has not been converted into Chinese patent medicine preparations. The authors collected 173 pieces of data based on ancient literature on Xiaoruwan by the method of bibliometrics and selected 99 pieces of effective data, involving 46 ancient books of TCM. The study analyzed the historical development origin, prescription names, formulation rules, dosage, drug origin, preparation method and usage, indications and functions, and other aspects of Xiaoruwan. The results showed that Xiaoruwan was presumably derived from Ying Hai Miao Jue Lun(《婴孩妙诀论》) written by TANG Minwang, a doctor in the Song Dynasty. In the records of ancient medical books, there are names such as Xiaoshiwan,Yangshi Xiaoruwan, and Kuaige Xiaoshiwan, but they are mainly recorded in the name of Xiaoruwan. The prescription was composed of Cyperi Rhizoma, Amomi Fructus, Citri Reticulatae Pericarpium, Massa Medicata Fermentata, Hordei Fructus Germinatus, and Glycyrrhizae Radix et Rhizoma. In terms of processing method, Cyperi Rhizoma, Massa Medicata Fermentata, and Hordei Fructus Germinatus are fried, Glycyrrhizae Radix et Rhizoma is processed, and raw materials of Amomi Fructus and Citri Reticulatae Pericarpium are used directly. In terms of function, it is effective in warming the middle, improving digestion, stopping vomiting, and digesting milk and food. The main indications include vomiting, diarrhea, night crying, and other diseases caused by milk and food stagnation. The dosage of the most used prescription in the records of ancient books is Cyperi Rhizoma 41.30 g, Amomi Fructus 20.65 g, Citri Reticulatae Pericarpium 20.65 g, Massa Medicata Fermentata 20.65 g, Hordei Fructus Germinatus 20.65 g, and Glycyrrhizae Radix et Rhizoma 20.65 g, which are prepared into pills. In the taking method, it is recommended to take it with warm boiled water or ginger soup after meals. The study summarized the historical evolution of Xiaoruwan and identified the key information, with a view to providing a reference for the modern development and research of Xiaoruwan.

ABSTRACT

OBJECTIVE@#To observe the short-term efficacy, long-term efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).@*METHODS@#Forty-two patients with CP/CPPS were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases). The patients in the acupuncture group were treated with acupuncture at bilateral Zhongliao (BL 33), Huiyang (BL 35), Shenshu (BL 23) and Sanyinjiao (SP 6); the needling depth of Zhongliao (BL 33) and Huiyang (BL 35) was 60 to 80 mm, while Shenshu (BL 23) and Sanyinjiao (SP 6) was directly punctured of 30 mm. The patients in the sham acupuncture group were treated with acupuncture at non-acupoints, including points 2 cm next to Shenshu (BL 23), Zhongliao (BL 33) and Huiyang (BL 35), and the midpoint of the connecting line between the spleen meridian and the kidney meridian. All the non-acupoints were treated with directly puncture of 2 to 3 mm. The needles were left for 30 min in both groups, once every other day in the first four weeks, three times a week, and twice a week in the next four weeks, totally 20 treatments. Before treatment, after treatment and in follow-up of 24 weeks after treatment completion, the National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) score and urinary flow rate were observed in both groups; the clinical efficacy and safety were evaluated.@*RESULTS@#Compared with those before treatment, the pain and discomfort scores, urination symptoms scores, quality of life scores and total scores of NIH-CPSI in both groups were reduced after treatment in the two groups (P<0.01), while each item score and total score of NIH-CPSI in the acupuncture group were reduced in follow-up (P<0.01, P<0.05). After treatment and in follow-up, each item score and total score of NIH-CPSI in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). After treatment, the maximum and average urinary flow rates in the acupuncture group were higher than those before treatment (P<0.05), and the average urinary flow rate in the acupuncture group was higher than that in the sham acupuncture group (P<0.05). The total effective rate was 75.0% (15/20) in the acupuncture group, which was higher than 42.9% (9/21) in the sham acupuncture group (P<0.05). No significant adverse reactions were observed in the two groups, and there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05).@*CONCLUSION@#Acupuncture could effectively alleviate the clinical symptoms, improve quality of life, and has a sustained, safe and reliable therapeutic effect in patients with CP/CPPS.

ABSTRACT

Objective: To analyze the clinical characteristics and risk factors of protein energy wasting (PEW) in children with chronic kidney disease (CKD). Methods: Clinical data of 231 children with chronic kidney disease hospitalized in Beijing Children's Hospital affiliated to Capital Medical University from January 2018 to January 2023 were retrospectively analyzed to explore the incidence of PEW. According to the diagnostic criteria of CKDPEW, they were divided into a CKDPEW group and a non PEW group. The comparison between the groups was performed by independent-sample t test and Chi-squared test, and the risk factors were analyzed by multivariate Logistic regression. Results: Among the 231 children, there were 138 males and 93 females, with a visiting age of 9.9 (7.9, 16.0) years; 6 cases were in stage 1, 14 cases in stage 2, 51 cases in stage 3, 36 cases in stage 4, and 124 cases in stage 5. A total of 30 children (13.0%) with CKD PEW were diagnosed at the age of 7. 1 (3.8, 13.2) years, including 1 case in stage 1, 1 case in stage 2, 5 cases in stage 3, 5 cases in stage 4, and 18 cases in stage 5. There were a total of 201 cases (87.0%) in the non PEW group, diagnosed at the age of 11.8 (8.5, 12.2) years, including 5 cases in stage 1, 13 cases in stage 2, 46 cases in stage 3, 31 cases in stage 4, and 106 cases in stage 5. The Chi-squared test and t test showed that the systolic blood pressure, diastolic blood pressure, birth weight and carbon dioxide binding capacity of the CKD PEW group were lower than those of the non PEW group ((109±22) vs. (120±20) mmHg (1 mmHg=0.133 kPa), (72±19) vs. (79±16) mmHg, (2.9±0.5) vs. (3.2±0.6) kg, (17±4) vs. (19±4) mmol/L,t=2.85, 2.14, 0.67, 2.63, all P<0.05). Multivariate logistic regression analysis showed that carbon dioxide binding capacity and birth weight were independent protective factors of CKDPEW in children (OR=0.81 and 0.36, 95%CI=0.73-0.90 and 0.17-0.77, respectively; both P<0.01); the risk of PEW in CKD children decreased by 0.187 times for every 1 mmol/L increment in carbon dioxide binding capacity, and 0.638 times for every 1 kg increment in birth weight. Conclusions: The incidence of protein energy expenditure in children with chronic kidney disease is lower than that in the previous researches. PEW can appear in CKD 1-2 stage, and attention should be paid to it in the early stage of CKD in clinical practice. Low birth weight CKD children are susceptible to PEW, and actively correcting metabolic acidosis can reduce the risk of CKDPEW.

ABSTRACT

Background Work-related musculoskeletal diseases (WMSDs) occur in a variety of occupational populations. Because of their various discomfort and serious disease burden, they have become an important issue worthy of attention in the field of occupational health. The prevention and control of WMSDs is one of the public health problems to be solved. Objective To evaluate the intervention effect on WMSDs among assembly workers in a railway vehicle manufacturing enterprise, so as to provide scientific basis for the prevention and control of WMSDs. Methods A total of 250 assembly workers in a railway vehicle manufacturing enterprise were selected using convenience sampling from August to December 2017. The Chinese Musculoskeletal Questionnaire was used for epidemiological investigation, and the Ergonomic Checkpoints was used for ergonomic inspection and worker interview. According to the above survey results, a six-month intervention plan including stepladder improvement and ergonomics training were implemented in the assembly workshop from September 2018 to February 2019. The intervention effects including the awareness of WMSDs, the exposure level of ergonomic load, and the occurrence of WMSDs symptoms were evaluated with relevant cross-sectional survey results before and after the intervention. The scores of WMSDs symptom intensity, symptom duration, and symptom frequency from low to high were 0-10, 1-4, and 1-5, respectively. Results After the intervention, the awareness rates of assembly workers on WMSDs types, affected body sites, influencing factors, preventive measures, and symptoms all increased from 52.3%, 51.9%, 25.5%, 19.1%, and 51.5% to 68.5%, 61.3%, 48.1%, 40.9%, and 61.3%, respectively (P<0.05). After the intervention, the proportion of assembly workers who "often" bend their head backwards frequently decreased from 34.6% to 21.8%, the proportion who "often" keep their trunk backward for a long time decreased from 26.6% to 15.0%, and the proportion who "never" raise their arms frequently increased from 3.4% to 9.0% (P<0.05). After the intervention, the scores of WMSDs symptom intensity in neck, shoulders, upper back, low back, elbows, hands/wrists, hips/thighs, knees, and ankles/feet all decreased, and the medians were mostly decreased from 6 to 3 (P<0.05); the scores of WMSDs symptom duration only decreased in neck (P<0.05) and there was no significant difference in the other body sites before and after the intervention; the median scores of WMSDs symptom frequency in low back, hands/wrists, and hips/thighs decreased from 3 to 2 (P<0.05). Conclusion The six-month intervention of stepladder improvement and ergonomics training among assembly workers in a railway vehicle manufacturing enterprise can improve workers' awareness of WMSDs, and reduce the exposure frequency of awkward postures and the intensity, duration, and frequency of WMSDs symptoms.

ABSTRACT

Background The prevalence rate of work-related musculoskeletal disorders (WMSDs) among manufacturing workers is relatively high and has been widely concerned. However, research on the prevalence and risk factors of multi-site WMSDs is still insufficient. Objective To explore the prevalence and risk factors of multi-site WMSDs of assembly workers in four manufacturing enterprises. Methods The "Chinese Musculoskeletal Questionnaire" was used to conduct a cross-sectional survey among 1401 assembly workers selected by convenient sampling in four manufacturing enterprises, and their demographic characteristics, the prevalence of WMSDs in various body parts, and the information about biomechanical factors, work organizations, work environment, and psychosocial factor exposure were collected. The prevalence of WMSDs and multi-site WMSDs were estimated, Pearson χ2 test was used for univariate analysis of multi-site WMSDs risk factors, and logistic regression was used for multi-factor analysis. Results The total prevalence rate of WMSDs was 54.9% (769/1 401). The top three affected sites were neck (41.4%), shoulders (30.7%), and wrist/hand (25.1%). The prevalence rate of multi-site WMSDs was 41.9% (587/1 401). The prevalence rates of multi-site WMSDs in railway vehicle assembly and riveting workers were higher than those in electronic parts processing and glass manufacturing workers (P<0.001). The results of logistic regression analysis showed that individual factors such as female (OR=2.09, 95%CI: 1.48−2.97) and drinking (OR=1.52, 95%CI: 1.05−2.18), biomechanics factors such as keeping head down for a long time (OR=1.37, 95%CI: 1.22–1.53), keeping bending frequently (OR=1.18, 95%CI: 1.03–1.34), and keeping arms up for a long time (OR=1.25, 95%CI: 1.10–1.41), work organizational factors such as electronic parts processing, railway vehicle assembly, and riveting (OR values were 3.23, 5.70, and 13.83, respectively), environmental factors such as temperature a little cold (OR=4.84, 95%CI: 1.90–12.37), noise seriously affecting work (OR=2.25, 95%CI: 1.23–4.11), and psychosocial factors such as high job demands (OR=1.47, 95%CI: 1.04–2.08), fatigue after work (OR=1.92−2.61) were risk factors of multi-site WMSDs. Conclusion The prevalence rate of multi-site WMSDs in assembly workers is high, and the main influencing factors include individual factors, awkward work postures, environmental factors, and psychosocial factors.

ABSTRACT

OBJECTIVES@#To investigate the current status of unplanned readmission of neonates within 31 days after discharge from the neonatal intensive care unit (NICU) and risk factors for readmission.@*METHODS@#A retrospective analysis was performed on the medical data of 1 561 infants discharged from the NICU, among whom 52 infants who were readmitted within 31 days were enrolled as the case group, and 104 infants who were not readmitted after discharge during the same period of time were enrolled as the control group. Univariate analysis and multivariate logistic regression analysis were performed to identify the risk factors for readmission.@*RESULTS@#Among the 1 561 infants, a total of 63 readmissions occurred in 52 infants, with a readmission rate of 3.33%. hyperbilirubinemia and pneumonia were the main causes for readmission, accounting for 29% (18/63) and 24% (15/63) respectively. The multivariate logistic regression analysis showed that that gestational age <28 weeks, birth weight <1 500 g, multiple pregnancy, mechanical ventilation, and length of hospital stay <7 days were risk factors for readmission (OR=5.645, 5.750, 3.044, 3.331, and 1.718 respectively, P<0.05).@*CONCLUSIONS@#Neonates have a relatively high risk of readmission after discharge from the NICU. The medical staff should pay attention to risk factors for readmission and formulate targeted intervention measures, so as to reduce readmission and improve the quality of medical service.

ABSTRACT

Objective:To discuss the principle and effect of augmentation rhinoplasty with auricular cartilage and expanded polytetrafluoroethylene.Methods:From January 2018 to January 2020, 161 patients (10 males and 151 females; aged from 19 to 48 years, with an average of 26 years) underwent " auricular cartilage plus expanded polytetrafluoroethylene" augmentation rhinoplasty in Nanfang Hospital of Southern Medical University. The expended polytetrafluoroethylene was carved into a willow leaf shape (I Shape) to fill the nasal dorsum, and the cartilage taking from cymba concha was constructed into an arched bridge shape for the nasal tip shaping. Pre-operative and 1-year post-operative measurements nasal length, nasal height, nasal depth, nasal columella height, nasal tip width, nasofrontal angle, nasolabial angle, survey of satisfaction and complication rate 1-2 years after operation were taken. The statistical analysis of nasal morphological indicators and nasal aesthetic indicators were employed.Results:The nose shape of 161 patients was improved to varying degree. All morphological indicators were improved, and difference was statistically significant ( P<0.05). The nasofrontal angle reached the standard in 90 cases, accounting for 55.9%; The nasolabial angle reached the standard in 143 cases, accounting for 88.8%. 2 cases had prosthesis (ePTFE) deviation and were corrected by surgical repair; 1 case had prosthesis (ePTFE) rejection and was corrected by prosthesis (ePTFE) removal surgery. Conclusions:Corresponding to the anatomical characteristics of the external nose, the prosthesis material is designed and made to correspond to the dorsum shape of the nasal stent. The shape of the alar cartilage, the prefabricated arched bridge shape of the cymba concha cartilage are used to reconstruct the nasal tip, which can effectively elevate the nasal dorsum, improve the protruding degree and rotation degree of the nasal tip, and have good long-term support. The flexibility and activity of the nasal tip are similar to the biological nose.

ABSTRACT

Objective:To analyze the molecular epidemiological characteristics of the Corona virus disease 2019 (COVID-19) cases in Shijiazhuang, which can reveal the origin of the outbreak and provide a scientific basis for COVID-19 prevention and control.Methods:From January 2 to January 8, 2021, a total of 404 samples from 170 COVID-19 cases were collected from the Shijiazhuang Fifth Hospital. The consensus sequence of 2019 novel Coronavirus(2019-nCoV) was obtained through multiplex polymerase chain reaction-based sequencing. The sequences of 170 COVID-19 cases were analyzed by the PANGOLIN, and the data were statistically analyzed by T-test.Results:Among the 404 COVID-19 samples, a total of 356 samples obtained high quality genome sequences (>95%,100×sequencing depth). The whole genome sequences of 170 COVID-19 cases were obtained by eliminating repeated samples. All 170 sequences were recognized as lineage B1.1 using PANGOLIN. The number of single nucleotide polymorphism arrange from 18-22 and most of the single nucleotide polymorphism were synonymous variants. All of 170 genomes could be classified into 48 sub-groups and most of the genomes were classified into 2 sub-groups (66 and 31, respectively).Conclusions:All cases in this study are likely originated from one imported case. The viruses have spread in the community for a long time and have mutated during the community transmission.

ABSTRACT

Objective:To study the risk factors for complications after endoscopic retrograde cholangiopancreatography (ERCP) in super-aged patients (≥80 years).Methods:Clinical data of 512 super-aged patients with pancreaticobiliary diseases who underwent 638 ERCP procedures at the Digestive Endoscopy Center, Zhongnan Hospital of Wuhan University, from July 2011 to June 2021, were studied retrospectively. Indications and results of the ERCP operations were analyzed. Multivariate logistic regression model was used to analyze the risk factors for ERCP-related complications.Results:The total success rate of ERCP cannulation in super-aged patients was 94.0% (600/638), which showed no difference compared with that of patients of <60 years old (2 433/2 557, 95.2%) or patients of 60~<80 years old (2 815/3 004, 93.7%) ( χ2=5.49, P=0.064). The overall incidence of post-ERCP complications was 15.2% (97/638), and the in-hospital mortality was 2.1% (11/512), which showed significant difference compared with patients of <60 years old (8/1 809, 0.4%) and patients of 60-<80 years old (21/2 127, 1.0%) ( χ2=13.39, P=0.002). Multivariate regression analysis showed that hypertension ( HR=1.94, 95% CI: 1.237-3.041, P=0.004), history of upper gastrointestinal reconstruction ( HR=2.28, 95% CI: 1.064-4.891, P=0.034), endoscopic sphincterectomy ( HR=1.65, 95%CI: 1.012-2.679, P=0.045), early procedure period ( HR=0.57, 95% CI: 0.352-0.923, P=0.022), operation time >30 minutes ( HR=1.74, 95% CI: 1.094-2.759, P=0.019), preoperative white blood cell count >9.5×10 9/L ( HR=2.66, 95% CI: 1.661-4.257, P<0.001) and procalcitonin ≥0.05 ng/L ( HR=2.54, 95% CI: 1.172-5.513, P=0.018) were independent risk factors for post-ERCP complications. Conclusion:ERCP is safe and effective for super-aged patients. However, much attention should be paid to post-ERCP complications of patients with hypertension, history of upper gastrointestinal reconstruction, endoscopic sphincterectomy, operation time >30 minutes, preoperative white blood cell count >9.5×10 9/L and procalcitonin ≥0.05 ng/L to avoid serious adverse events such as mortality.

ABSTRACT

Fingerprints of 18 batches of substance benchmark of Shentong Zhuyu Decoction(SZD) were established by UPLC under the following conditions: Waters Sun Fire C_(18) column(3.0 mm×150 mm, 3.5 μm), column temperature of 35 ℃, gradient elution with mobile phase of acetonitrile(A)-0.1% phosphoric acid aqueous solution(B) at the flow rate of 0.4 mL·min~(-1), and detection by wavelength switching. A total of 16 common peaks were identified. The similarities among the fingerprints were calculated by Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(2012 Edition) and the result showed they were in the range of 0.911-0.988. Based on the 16 common peaks, cluster analysis(CA), principal component analysis(PCA), and partial least square discriminant analysis(PLS-DA) all categorized the 18 batches of samples into two groups(S1, S2, S5-S8, S14, and S17 in one group, and S1, S2, S5-S8, S14, and S17 in another), and 11 most influential components were screened. Five known components with great difference among samples(hydroxysafflor yellow A, ferulic acid, benzoic acid, ecdysone, and ammonium glycyrrhizinate) were determined. The combination of multi-component content determination and fingerprints can reflect the overall cha-racteristics of the primary standards of SZD, which is simple, feasible, reproducible, and stable. This study can serve as a reference for the quality control of the primary standards of SZD.

ABSTRACT

Objective:To analyze the detective value of placental tissue resistin, human lipid carrier protein (LCN) and blood glucose and lipid metabolism in pregnant women with gestational diabetes mellitus (GDM) complicated with preeclampsia (PE) , providing guidance for the early treatment of GDM complicated with preeclampsia.Methods:96 pregnant women with GDM complicated with PE (GDM-PE group) admitted to Yantai Yantaishan Hospital from Jan. 2017 to Jan. 2020 were selected and retrospectively studied. According to the ratio of 2:1, the pure GDM pregnant women (GDM group) and 48 normal pregnant women (the control group) were selected. The placenta tissue resistin and LCN levels were determined by immunohistochemistry. Blood samples were collected to determine the glucose and lipid metabolism. The pregnancy outcomes of each group were compared and the relationship between resistin, LCN, glucose and lipid metabolism and GDM complicated with PE was analyzed.Results:Fasting blood-glucose (FBG) was (4.57±0.66) mmol/L in GDM group and (5.23±0.61) mmol/L in GMD-PE group. FINS (11.97±1.5) mIU/L, (15.12±3.52) mIU/L were higher than those of control group (4.11±0.23) mmol/L, (6.75±1.34) mIU/L ( P<0.05) . FBG, FINS, glycosylated hemoglobin (HbA1c) in GDM-PE group were higher than those in GDM group. TC) (6.71±1.63) mmol/L, triglyceride, TG (6.59±0.87) mmol/L was higher than that of control group (5.87±0.73) mmol/L, (4.57±0.59) mmol/L and GDM group (6.02±1.55) mmol/L, (4.71±0.63) mmol/L ( P<0.05) . high density lipoprotein cholesterol (HDL-C) (1.21±0.34) was lower than that of control group (1.54±0.39) and GDM group (1.55±0.43) ( P<0.05) . The positive rates of resistin 85.42%, 60.42%, LCN 81.25%, 56.25% in GDM-PE group and GDM group were higher than those in control group 39.58%, 31.25% ( χ2=32.096, 4.167; 34.975, 6.095, both P<0.05) . The positive rates of resistin and LCN in GDM-PE group were higher than those in GDM group ( χ2=11.322, 11.257, both P<0.01) . The gestational age of delivery in GDM-PE group was (37.11±2.06) weeks earlier than that in GDM group (38.21±1.75) weeks and control group (38.36±1.42) weeks ( F=9.836, P<0.05) . The birth weight of neonates (2 905.45±356.79) g was lower than that of control group (3 321.52±366.46) g and GDM group (3 425.14±269.87) g ( F=46.606, P<0.05) . Postpartum blood loss (415.34±126.75) ml was significantly higher than that of GDM group (338.65±105.63) ml and control group (298.42±75.26) ml ( F=19.932, P<0.05) . The preterm birth rate of 20.83% was higher than that of the GDM group (8.33%) and the control group (4.17%) ( χ2=9.075, P<0.05) . The postpartum blood loss of the GDM group was higher than that of the control group ( t=-2.148, P<0.05) . The incidences of fetal distress, premature rupture of membranes, fetal growth restriction and postpartum hemorrhage in GDM-PE group were higher than those in control group ( χ2=4.571, 6.867, 5.941, 5.123, P<0.05) . The protein expressions of resistin and LCN in placenta of pregnant women with GDM-PE were positively correlated with FBG, FINS, TC and TG ( r=0.517, 0.463, 0.559, 0.521, 0.485, 0.497, 0.557, 0.571, P<0.05) . Was negatively correlated with HDL-C ( r=-0.317, -0.357, P<0.05) . Conclusions:The positive rate of resistin and LCN in the placenta tissue of pregnant women with GDM complicated with PE is higher than that of GDM and normal pregnant women, their disorder of glucose and lipid metabolism is more obvious, and the incidence of adverse maternal and infant outcomes is higher. It is speculated that resistin and LCN may synergistically affect the metabolism of glucose and lipids causing adverse pregnancy outcomes in GDM complicated with PE.

ABSTRACT

Objective:To investigate the accuracy and feasibility of 3D-printing individualized template-guided and CT-guided 192Ir interstitial brachytherapy in the central recurrent gynecologic tumors by comparing pre-plan and intraoperative physical dosimetric parameters. Methods:This study involved 38 patients with central recurrent gynecologic tumors who underwent 3D printing individual template (3D-PIT)-assisted and CT-guided 192Ir interstitial brachytherapy in the Department of Radiation Oncology of the Peking University Third Hospital from Jan 2018 to Dec 2019.The prescription doses for the target tumor areas were 10-36 Gy to be delivered at 5-6 Gy/fraction for 2-6 fractions.The pre-plan and intraoperative dosimetric parameters were compared, including the minimum prescription doses delivered to 90% and 100% of target volume( D90, D100)and the mean percentage of volume receiving 100% of the prescription doses ( V100). Meanwhile, the doses delivered to 2 cm 3 ( D2 cm 3) of organs at risk (bladders, rectums, and colons) were analyzed.The quality parameters of the brachytherapy were studied, including conformity index (CI), homogeneity index (HI), and external index (EI) of the target volume.Perioperative complications were also observed. Results:A total of 194 treatments were included.During the treatment, 5-13 (median 6) needles were inserted, with a prescription dose of 5-6 Gy per fraction.There were no statistical differences between pre-plan and intraoperative D90, D100, V100, CI, HI, and EI as well as the D2 cm 3 of bladders and colons at risk ( P>0.05). In contrast, for the D2 cm 3 of rectums, the intraoperative dose was slightly higher than the pre-plan dose, showing a statistical difference ( t=-0.335, P=0.027). Conclusions:The 3D-PIT-assisted and CT-guided 192Ir interstitial brachytherapy at a high dose rate is accurate and feasible in the treatment of recurrent gynecologic tumors, meeting the pre-plan dose requirement.

ABSTRACT

Objective:To explore the accuracy of CT-guided 125I seed implantation assisted by a navigation system and 3D-printing template in the treatment of recurrent malignant pelvic tumors by comparing pre-plan and intraoperative physical dosimetric parameters. Methods:This study involved 15 patients with recurrent malignant pelvic tumors who received CT-guided radioactive 125I seed implantation assisted by a navigation system and 3D-printing template in the Peking University Third Hospital from Dec 2018 to Feb 2020.Seven of the patients had cervical cancers, seven had rectal cancers, and one had prostate cancer.The median age was 55 years (34-84 years old). The prescription dose was 100-150 Gy.The pre-plan and post-implant data were compared, including the number of implanted seeds, implantation needle number, and some dosimetric parameters such as the minimum prescription doses delivered to 90% and 100% of target volume( D90, D100), mean percentages of volume receiving 100%, 150%, and 200% of the prescription doses( V100, V150, and V200), conformity index(CI), external index(EI), and homogeneity index(HI)of the target volume. Results:The median lesion volume was 29.20 cm 3, the median seed number was 54, and the median D90 was 150 Gy.The post-implant V150 was lower than pre-plan V150 (64.1% vs. 67.1%, t=2.937, P=0.011), and the post-implant mean HI was higher than pre-plan HI (32.01% vs. 26.68%, t=-2.950, P=0.011). There were no significant differences in other dosimetric parameters before and after seed implantation. Conclusions:With CT-guided radioactive seed implantation assisted by a navigation system and 3D-printing template in the treatment of recurrent malignant pelvic tumors, the actual postoperative dose could meet the preoperative plan requirement, ensuring the accuracy and consistency of the dose delivered.

ABSTRACT

In this study, a composite cell model for evaluation of idiosyncratic drug-induced liver injury (IDILI) was established in vitro from the perspective of immune inflammation. And this model was used to evaluate the risk of IDILI for 2,3,5,4'-tetrahydroxy-cis-stilbene-2-O-β-glucoside (Cis-SG) and 2,3,5,4'-tetrahydroxy-trans-stilbene-2-O-β-glucoside (Trans-SG). To determine the low, medium, and high dosage of Cis-SG and Trans-SG, CellTiter-Glo® 3D Cell Viability Assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of HepG2 cells in three dimensional (3D) culture, and MTT assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of THP-1 derived macrophages. THP-1 derived macrophages were incubated by Cis-SG and Trans-SG directly or supernatants from HepG2 cells incubated with them. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-1β (IL-1β) in the supernatants of the THP-1 derived macrophages. Western blot and reverse transcription-polymerase chain reaction (RT-PCR) were used to determine the expression of apoptosis-associated speck-like protein (ASC), Nod-like receptor protein 3 (NLRP3), cysteinyl aspartate specific proteinase-1 (caspase-1), and IL-1β in THP-1 derived macrophages. The results showed that there was no effect on the secretion of IL-1β in THP-1 derived macrophages incubated by Cis-SG and Trans-SG directly. However, the secretion of IL-1β, the protein and mRNA expression of ASC, NLRP3, caspase-1, and IL-1β significantly increased in THP-1 derived macrophages incubated by supernatants from HepG2 cells incubated with 1, 5, and 25 μmol·L-1 Cis-SG or 25 μmol·L-1 Trans-SG. In summary, the composite cell model for evaluation of IDILI established in vitro has been successfully applied in testing Cis-SG and Trans-SG. This composite cell model is helpful to evaluate and screen drugs with IDILI risk in vitro preliminarily, which provides methods for predicting and solving the idiosyncratic liver toxicity of drugs.

ABSTRACT

OBJECTIVE@#To study the long-term clinical effect of multicenter multidisciplinary treatment (MDT) in children with renal malignant tumors.@*METHODS@#A retrospective analysis was performed on the medical data of 55 children with renal malignant tumors who were diagnosed and treated with MDT in 3 hospitals in Hunan Province from January 2015 to January 2020, with GD-WT-2010 and CCCG-WT-2016 for treatment regimens. A Kaplan-Meier survival analysis was used to analyze the survival of the children.@*RESULTS@#Of the 55 children, 10 had stage I tumor, 14 had stage Ⅱ tumor, 22 had stage Ⅲ tumor, 7 had stage IV tumor, and 2 had stage V tumor. As for pathological type, 47 had FH type and 8 had UFH type. All children underwent complete tumor resection. Of the 55 children, 14 (25%) received preoperative chemotherapy. All children, except 1 child with renal cell carcinoma, received postoperative chemotherapy. Among the 31 children with indication for radiotherapy, 21 (68%) received postoperative radiotherapy. One child died of postoperative metastasis. The incidence rate of FH-type myelosuppression was 94.4%, and the incidence rate of UFH-type myelosuppression was 100%. The median follow-up time was 21 months and the median survival time was 26 months for all children, with an overall survival rate of 98% and an event-free survival rate of 95%.@*CONCLUSIONS@#Multicenter MDT has the advantages of high success rate of operation and good therapeutic effect of chemotherapy in the treatment of children with renal malignant tumors, with myelosuppression as the most common side effects, and radiotherapy is safe and effective with few adverse events. Therefore, MDT has good feasibility, safety, and economy.
