ObjectiveTo explore the best measurement of waist circumference related with intra-abdominal fat volume evaluated by CT scan.MethodsHeight,weight,and hip circumference were measured among 147 subjects aged over 18 years old.Waist circumference was measured at 3 different levels:the upper brim of the iliac crest ( WC1 ),the midpoint between costal brim and iliac crest ( WC2 ),and the umbilicus ( WC3 ).The intra-abdominal fat volume was evaluated by CT scan.ResultsIntra-abdominal fat volume was significantly higher in men than in women [ ( 1 236.0±608.4 vs 931.0±665.0)cm3,P＜0.01 ].Correlation analysis showed that WC1 ( r =0.634),WC2( r=0.677),and WC3 (r =0.712)were positively correlated with intra-abdominal fat volume ( all P＜0.01 ).Partial correlation analysis adjusted by gender,weight,or body mass index showed that the correlation of intra-abdominal fat volume with WC3 ( r were 0.488 and 0.432) was better than that with WC1( r were 0.347 and 0.293 ) and WC2 ( r were 0.424 and 0.365 ).Multiple linear stepwise regression analysis demonstrated that WC2 and WC3 were independently associated with intra-abdominal fat volume and WC3 was the strongest impact factor (β =0.270,R2c =0.504,P＜0.01 ).ConclusionsWaist circumference is a simple anthropometric measurement parameter reflecting the degree of intraabdominal fat accumulation.All three different measurements of waist circumference may reflect intra-abdominal fat volume,while waist circumference at umbilical level is the best among them.

Objective To explore the induction of basic fibroblast growth factor (bFGF)-chitosan carrier transforming the adult rat bone marrow mesenchymal stem cells (rMSCs) into nerve cells. Methods rMSCs were detected qualitatively and counted quantitatively by immunohistochemistry after they were induced into nerve cells, such as neural stem cells neurons and astrocytes. The methyl thiazolyl tetrazolium (MTT) chromometry assay was carried out to determine the cell viability. Results rMSCs induced by bFGF-chitosan carrier expressed neural stem cell marker nestin, neuron marker β-tubulin Ⅲ and astrocytes marker glial fibrillary acidic protein (GFAP). Nestin expressed more in the bFGF-chitosan group, and reached its maximum (49.40%) at the 9th day. Conclusion bFGF-chitosan carrier can induce the adult rMSCs differentiate into neural stem cells in a high proportion.

Objective To investigate the efficacy of sequential ERCP and laparoscopy for acute biliary pancreatitis (ABP).Methods A total of 80 patients with ABP were randomly divided into 2 groups to receive sequential ERCP and laparoscopy (observation group,n=40) or traditional surgery (control group,n=40).Clinical data including abdominal pain relief time,recovery time of white blood cell,blood amylase and liver function,hospital stay,complication rate and mortality were analyzed.Results ERCP failed in 1 patient in observation group,and the remaining 39 patients (97.5％) were recruited into the study.There were significant differences between 2 groups in regarding of abdominal pain relief time (7.7±2.7 d vs.11.4±3.7 d),recovery time of white blood cell ( 9.7±2.6 d vs.13.3±3.9 d ),blood amylase ( 8.2±2.1 d vs.12.5±3.3 d ),liver function ( 12.5±5.1 d vs.21.3±6.5 d ),hospital stay ( 16.1±5.1 d vs.23.3±7.6 d ) and rate of complication ( 12.8％ vs.30.0％ ).There was no significant difference in morbidity between 2 groups (5.1％ vs.7.5％).Conclusion Sequential ERCP and laparoscopy is effective for ABP.

Books on Traditional Chinese Medicine (TCM) in French version have a large readership in France as well as in other French-speaking countries in Europe and Africa. From 1977 to 2020, 10 Chinese publishing houses have published 44 TCM works in French, among which 7 are on TCM popular readings and 37 on academic ones. If classifying by TCM disciplines, 29 are on acupuncture & Tuina (including teaching charts), 6 on health preservation, 5 on TCM culture, 3 on TCM terminology dictionaries and 1 on Chinese Materia Medica. With acupuncture as the most popular subject, the published ones have diversified themes and are of high-quality and academic value. Representative works are enlightening on the issues such as cooperative copyright mode, TCM standardization, academic value of published books, French translation of TCM, and domestic book market, etc. However, classic TCM monographs are short of French translations in China, and TCM books in French are still in a niche market, with uneven economic and social efficacies. We should value the promotion of accurate TCM knowledge by our French version of TCM publications, for the translations overseas are sporadically mistaken. Books of such are highly competitive in the international market, thus in-depth investigation, accuracy in topic selection, and all-media publishing should be conducted.

Objective:To explore the impacts of workload and expected income index on the salary satisfaction of medical staff at public hospitals.Methods:From October 15th to November 10th, 2020, the salary system reform monitoring questionnaire for medical staff in public hospitals formulated by development center for medical science & technology National Health Commission was adopted to evaluate the workload, actual income, expected income and salary satisfaction of 120 pilot public hospitals for salary reforms in 21 cities (prefectures) in Sichuan province. The questionnaire survey was conducted among 8 651 medical staff of these hospitals. Descriptive analysis was carried out on the results of the questionnaire; the ratio of expected income to actual income, namely the expected income index, was used to reflect the relative difference between expected income and actual income; χ2 test and binary logistic regression were used to analyze the influencing factors of salary satisfaction. Results:8 133 valid questionnaires were recovered. The average working time per week of the survey subjects was 48.17 hours, and the average longest continuous working time was 15.30 hours; 85.63% (6 964) of the medical staff had expected income index greater than 1. The average score of salary satisfaction was 58.22 points and 57.72% (4 694) of the medical staff were dissatisfied. The longer the continuous working time (16-72 h versus 8-9 h, OR=0.755), the greater the expected income index (>1 versus =1, OR=0.522), and the lower the salary satisfaction. Conclusions:The workload of medical staff was heavy, the salary failed to meet the expected level, the sense of satisfaction was low. It is suggested to monitor in real time and dynamically adjust the workload of medical staff in combination with the actual situation, formulate the salary level in line with the technical labor value of different medical staff, and establish a comprehensive performance appraisal mechanism.
