Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

BACKGROUND: Alcohol consumption has been observed to be a contributing factor in liver damage. However, very few studies have tried to decipher the correlation between patients with liver disease and alcohol consumption. Therefore, this study was planned to determine the prevalence of alcohol consumption among patients with liver disease, and to evaluate the risk factors, liver diseases, and chronic medical conditions associated with alcohol drinking. METHODS: A cross-sectional study was conducted among patients with liver disease in 30 provinces, autonomous regions, and municipalities across China. All participants answered the questionnaire, which led to the calculation of Alcohol Use Disorders Inventory Test (AUDIT) score for each patient. Based on this score, low-risk drinkers, hazardous drinkers, and harmful drinkers were defined as having AUDIT score of <8, between 8 and 15, and ≥16, respectively. RESULTS: A total of 1489 participants completed the questionnaire. Based on this information, 900 (60.44%) participants were classified as alcohol drinkers. Among these, 8.66% were ex-drinkers, 22.10% were low-risk drinkers, 17.13% were hazardous drinkers, and 12.56% were harmful drinkers. Further investigation of the association between alcohol consumption and other baseline characteristics of patients with liver disease revealed that usually men <40 years old, participants having higher family annual income, having college degree or higher education, living alone, having higher body mass index (BMI), current smokers, and ex-smokers had significant association with higher risk of alcohol consumption. In addition, among the 18.07% of the participants with cirrhosis, it was observed that risk of cirrhosis increased with higher alcohol consumption. Furthermore, harmful drinkers showed greater odds of hypertension and heart diseases, while hazardous drinkers and harmful drinkers, both had greater odds of hyperlipidemia. CONCLUSIONS Overall our analyses indicated that among the patients with liver disease in China, there was high rate of alcohol consumption and dependence. Alcohol consumption usually associated with men <40 years old, higher family income, education level, living alone, high BMI, and smoking. Increased alcohol consumption not only increased the risk of cirrhosis, but also enhanced the risk of hypertension, heart diseases, and hyperlipidemia.

OBJECTIVE: To summarize and critically assess the inhibitory effects of Chinese herbal medicine (CHM) on tumor volume and tumor weight for the treatment of osteosarcoma (OS) in mouse models. METHODS: PubMed, Embase, Web of Science, China Knowledge Resource Integrated Database (CNKI), Wanfang Database, VIP Database, and Chinese BioMedical (CBM) were searched since their inception dates to March 10, 2016. Two reviewers independently selected the controlled studies estimating effects of CHM on mouse OS by administration in vivo. A pair-wise meta-analysis was performed. Twenty-five studies with adequate randomization were included in the systematic review. RESULTS: CHM may significantly inhibit OS growth in mice, as assessed using the tumor weight [20 studies, n=443; 290 for CHM and 153 for the control: pooled mean difference (MD)=-2.90; 95% confidence interval (Cl): -3.50 to -2.31: P<0.01], tumor volume (16 studies, n=382; 257 for CHM and 125 for the control; pooled MD =-2.57; 95% Cl: -3.33 to -1.80; P<0.01) and tumor growth inhibition rate. CONCLUSION CHM could significantly inhibit the growth of OS in mouse models, which might be supportive for the design of preclinical and clinical trials in future.

Objective To investigate the epidemic characteristics of human brucellosis in Jiangxi province from 2011 to 2017，thereby providing reference for future prevention and control work. Methods We analyzed the case information reported in the National Notifiable Infectious Diseases Reporting Information System of Jiangxi Province during 2011-2017 by combining with the monitoring data. Results A total of 239 cases were recorded over these six years, with an average incidence rate of 0.08/100 000. Most cases and agglomerations were concentrated in the Nanchang area (48 cases/4 cases), with the case distribution ranging from 1 in 2011 to all in 2016, and the number of counties(districts) involved had increased from 1 in 2011 to 68 in 2017, which increased rapidly year by year ( 2= 94.31, P<0.001). The gender ratio was 3.12 ∶〗1(181 ∶〗58). Most cases were concentrated in the 40-65 age group, while farmers and herdsmen were high-risk population, accounting for 59.83 % (143/239). The incidence of brucellosis peaked from May to September (May peak and September peak). In 2012-2017, 7 160 blood samples were collected from risk population, with 95 being positive for Brucella (1.33 %). From 2013 to 2017, 62 strains of the Brucella, 4 were Brucella melitensis type1, 54 were Brucella melitensis type3 and 4 were Brucella suis were isolated from 193 cases. Conclusions The human brucellosis was aggravated in Jiangxi province, with the expansion of regional scope. Therefore, more efforts should be focused on regulation to prevent and control brucellosis better.

Quality marker(Q-marker) is a new concept and pattern for quality control of traditional Chinese medicine(TCM),which will lead the development direction for quality control of TCM.Among them,how to characterize the overall quality attribute of TCM and its biological effect,is a critical scientific problem in the study of Q-marker.In this paper,integrated pharmacology is utilized to screen out and confirm the Q-marker from the complex system of TCM,so as to solve the critical scientific problem.System biology in vivo is firstly applied to establish the correlation of chemical fingerprints of TCM,their metabolic fingerprints,network targets,biological effects and efficacy of TCM,which is used to preliminary screen out Q-marker of TCM.Following that,a pharmacological method in vitro,including intestinal absorption in vitro coupled with bioactivity assessment,is employed to simultaneously determine the absorbed doses of TCM and evaluate their biological activity.Furthermore,data mining is utilized to establish the exact quantitative mathematic model between Q-marker of TCM and bioactivity.Meanwhile,two representative examples,including Yuanhu Zhitong tablets,Xinsuning capsules,are introduced to identify Q-marker of TCM and establish their quality standards related with bioactivity,which will be beneficial to improve the level of quality control of TCM and ensure the effectiveness and safety of clinical applications.

Objectivc To compare the accuracy and practicability of OPD-Scan Ⅲ marker methods and slit light narrow band marker methods in phacoemulsification and Toric IOL implantation.Methods A prospective randomized controlled study was conducted in 70 eyes of 70 patients with regular astigmatism (1.00-3.00 D).All patients underwent phacoemulsification and Toric IOL implantation and were randomly divided into two groups according to preoperative marker methods:observant group,in which OPD-Scan Ⅲ marker methods were used in 35 eyes of 35 patients,and control group,with application of slit light narrow band marker methods in 35 eyes of 35 patients.The postoperative visual acuity,residual astigmatism and deviation of lens axis (LAD) were observed and compared between the two groups.Results The uncorrected visual acuity (UCVA) between preoperative data and 3 months after surgery was statistically significant [(0.11 ± 0.09) vs.(0.59 ± 0.25)] (P =0.000).The difference in the postoperative 1 day and 3 months LAD was no statistically significant (P ＞ 0.05).The astigmatism between preoperation and 3 months after treatment was significant [(1.88 ± 0.49) D vs.(0.54 ± 0.30) D] (P =0.000).There was no significant difference in LAD between the two groups neither the first day nor 3 months after operation (both P =0.621).Conclusion OPD-Scan Ⅲ marker methods and slit light narrow band marker methods are both highly accurate and practical,but the former requires less for operator and is more easily accepted by patients.

The strength of the protective support met the requirements, and the maximum deformation of the support bar was 15 mm after the suspension of the lead curtain.Conclusion The X-ray protection module gains advantages in design, structure, operation,rapid deployment and withdrawal, handling and transport as well as protective effective according to GB 18871—2002 regulation, and thus can be used for X-ray diagnosis at peace and war time.

Objective To investigate the influence of body mass index(BMI) on the prognosis of patients who had received elective PCI.Methods The study population consisted of 2964 consecutive patients with electivePCIs performed between July 2009 and September 2011. The patients were divided into three groups based on their preoperative BMI levels:the normal group( BMI<24.0 kg/m2,n=810); the overweight group( 24.0 kg/m2≤BMI<28.0 kg/m2,n=1454) and the obese group(BMI≥28.0 kg/m2,n=700). We examined the association between baseline BMI levels and postoperative mortality through a mean(571.5±130.8)days of follow up.Results Patients with high BMI had a higher percentage of comorbidities compared with the normal BMI group. The results of multivariate Cox regression analysis revealed that preoperative BMI was inversely associated with mortality after adjustment for other factors (HR 0.896,95％ CI 0.821-0.977,P=0.031). Compared with the obese group, the hazard ratios for risk of mortality in the overweight and the normal groups were 1.908(95％CI 0.689-5.291,P=0.213) and 2.241(95％CI 1.154-4.350,P=0.017).Conclusions For patients undergoing elective PCI, individuals with obesity and overweight had the better prognosis than those with normal BMI.
