OBJECTIVE To study the phenomenon of hepatitis B surface antigen(HBsAg) and antibody(HBsAb) both positive in blood samples.METHODS Using electro-chemo-luminescence immune system E170 to detect HBsAg and HBsAb in clinical samples and retest the both positive cases by another two reagents for HBsAg and another three reagents for HBsAb.RESULTS All 7332 samples showed 140 both HBsAg and HBsAb positive(1.9%) and 73 of them were retested for HBsAb by another three reagents which gave altogether 24 positive results,which was not related to each other.Those gave higher HBsAb value by E170 showed higher positive rate by Abbott reagent.CONCLUSIONS HBsAg and HBsAb both positive results are not rare.It may be due to the interactions between the patient and the infected hepatitis B virus.Besides,the quality of reagents and correct lab operating procedures may also affect the test results.

Objective To study the effects of the Chinese herbal compound (Erzhiwan, Shixiaosan and combined formula) on cholestasis-induced liver fibrosis rat’s uPA. Methods Bile duct ligation method was used to make the model of cholestasis-induced liver fibrosis. One week after the operation, the rats were randomly divided into five group (model group, UDCA group, Erzhiwan group, Shixiaosan group and hefang group). Each medicine intervention group was given corresponding medicine by intragastric administration. Sham and model group were given sodium chloride with equal dosage. At the end of 4th week, all rats were sacrificed and sampled. General state of health, hepatic function (ALT, AST, ALP, TBil) and pathological histology of hepatic tissue were recorded and measured. Results Compared with the sham group, the level of ALT, AST, ALP, TBil and the degree of liver fibrosis in model group were advanced significantly. Compared with model group, three Chinese herbal compound decreased serum level of ALP, ALT and AST (P

An international symposium on the standard surgical treatment of morbid obesity and type 2 diabetes mellitus was held in Florida, USA in March 2011. An expert panel from all over the world attended the meeting. The expert panelists discussed and established International Sleeve Gastroectomy Expert Panel Consensus Statement : best practice guidelines based on experience of more than 12,000 cases, which made a very commendable attempt in standardized surgical pathway of sleeve gastroectomy. Based on clinical experience over 10 years and the understanding of the consensus , this paper discusses the learning curve, preoperative preparation, indications/contraindications, surgical technique, management and prevention of complications, and post operative management.

Objective Application of Case-based teaching method (CTM) in the class of Experimental Animal Quality Control aims to break the traditional teacher-centered and textbookcentered teaching model,to invoke students' interest and creativity by integrating practice and theory,and to cultivate their capacity in identifying,analyzing and solving problems.Methods According to different requirements of teaching contents,students were organized to discuss practical cases about quality control of experimental animals through problem-centered learning style.Results Students' capacity was enhanced in terms of problem solving with acquired knowledge,and the ability to pursue new knowledge,the intriguing and vivid cases stimulated students' interest,activated classroom atmosphere,and helped improve teaching efficiency.Conclusion Experimental animal quality control is a complicated system; Case-based teaching method leads to higher efficacy of the course of Experimental Animal Quality Control.

Objective To evaluate the compliance effect of secondary prevention on high risk patients of gastric cancer and to investigate their knowledge,attitudes,and practice about gastric cancer.Methods 206 high risk patients of gastric carcinoma cancer were investigated with questionnaires.Results of all cases,54 patients were compliant,69 patients semi-compliant,and 83 patients were not compliant in monitoring cohort.The results showed distribution of the compliant patients was significantly different with their gender,occupation and family income per person,and not significant with their education background.Conclusion The compliance and KAP of the patients on high risk for gastric cancer aren't satisfied,which needed to be enhanced in the future.

Objective:To compare the immunology parameters and stress hormone in two groups of patients with lung cancer after radical operation and provide reference to clinical surgery.Methods:From March 2015 to March 2016, 72 cases in our hospital were accepted surgical treatment for lung cancer and divided into observation group and control group. Among them 36 cases of video-assisted thoracoscopy lung cancer radical surgery for the treatment of patients in mind as the observation group, 36 cases of open chest lung cancer radical operation were recorded as control group, respectively comparing two groups of patients with preoperative and postoperative 3 days red cell immune index, index of cellular immunity, stress hormone level and blood rheology index.Results:3 days after operation, the observation group in terms of RBC-C3b, RFER levels were significantly higher than those of control group and RBC-IC and RFER were significantly lower than those in the control group. 3 days after operation, the observation group CD3+, CD4+, CD3+CD4+ were significantly higher than those of the control group, while CD8+ was significantly lower than that of the control group. 3 days after operation, the observation group NE, Cor, angiotensin II (ANG II) was significantly higher than that of the control group (t=2.181,t=10.320,t=5.924;P<0.05). 3 days after operation in observation group, the plasma viscosity, erythrocyte sedimentation equation K value were significantly lower than those in the control group. The differences were statistically significant (t=29.698,t=7.411;P<0.05).Conclusion:The side-effect of thoracoscopy radical resection of lung cancer is small, and it has more advantages compared with open chest lung cancer radical operation.
