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

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.

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.

It is one of the key problems for the development of Chinese medicine to standardize the diagnosis of syndromes. The authors mainly discuss the ideas and methods of the study of standardization of syndrome diagnosis by retrospective analysis, also put forward the following suggestions: (1) the main ideas of this study should be based on the comparison of the diseases and their relevant syndromes and the predictive diagnosis of syndromes by the effects of herbal prescription treatment; (2) they are important ways to carry out multicenter, large sample and perspective clinical trials on the basis of the investigation and study of literature, consultation of experts and retrospective case review, and following the principles of clinical epidemiology, and to use the methods of evidence-based medicine to do systemic evaluation on the criteria of syndrome diagnosis; (3) they are important sectors of the study of standardization of syndrome diagnosis to enhance the objective studies on the four diagnostic methods of traditional Chinese medicine, and to do the functional studies under the conduction of systems biology; (4) Both data excavation technology and computer intelligence are the important technique supporting this study.

Along with the changes of disease spectrum, medical models and health concept, people pay more and more attention to the diagnostic and therapeutic approaches of traditional Chinese medicine (TCM). With the effect assessment being changed from disease-based model to patient-based model, how to scientifically and objectively explain the validity of TCM has become the premise for further development of TCM and dissemination of it throughout the world. In this article, the authors analyzed the status quo and problems of the effect assessment of TCM, and proposed some general methods for clinical effect assessment of TCM, including formulating criteria for syndrome differentiation under the guidance of TCM theories, paying attention to quality of life, proper selection of indexes for outcome assessment, application of modern clinical study methods, such as the methods of evidence-based medicine and clinical epidemiology, designing randomized controlled trials, multi-subject co-operation, strict supervision of the quality of researches, and establishment of organizations for professional training.
