1.Development and verification of an ELISA for quantitatively detecting Japanese encephalitis virus antigen
Chinese Journal of Clinical Laboratory Science 2006;0(06):-
Objective To develop a double antibody sandwich ELISA for quantitatively detecting Japanese encephalitis virus(JEV) antigen.Methods The anti-JEV polyclonal antibodies were used to coat ELISA plates.Anti-JEV monoclonal antibodies were used as enzyme-labeled conjugate.A standard curve based on known amounts of JEP antigen was established by the ELISA.Various parameters of the assay were analyzed.Results The optimal linear range was 12.5~200 U/ml(r=0.9989).The quantitation limit was 12.5 U/ml.The recovery rate for the accuracy test was 85.0%~103.3%.The coefficients of variation for intra-assay and inter-assay precision were 4.3%and 5.5%respectively.No cross-reaction was observed with HAV vaccine,influenza vaccine,Vero cell Iysates,newborn bovine serum,or human albumin.Conclusions The data indicate that the ELISA developed in this study has high specificity,precision, accuracy,and stability.The assay should be suitable for quantitative determination of JEV antigen in various vaccine products.

Chinese Journal of Medical Education Research 2003;0(04):-
Objective To explore the preliminary practice of Clinical Scenario Mode in the teaching of surgery. Methods Clinical Scenario Mode was stimulated or rebuilt by the cooperation of teachers and Standardized Patients (SP) to introduce relative theories and raise discussions in the surgery lectures of five-year clinical medicine students in grade 2004 and grade 2005. Results Lectures with the application of Clinical Scenario Mode were reported positively by students from the survey. It improved students’learning motivation,enhanced teaching quality,and optimized the allocation of resources. Discussion With the combination of the advantages of lecture based learning (LBL) and problem based learning (PBL),Clinical Scenario Mode can be considered as the linkage to the widespread use of PBL,and should be widely applied in the medical teaching practice.

Objective To investigate the beneficial effect on enterocyte-like cells HT-29 through adhesion of Lactobacillus. Methods Using viable bacteria counting method to evaluate inhibition of Escherichia coli adhesion and invasion to enterocyte-like cells by incubation with Lactobacillus together. Cellular membrane permeability and cell viability were examined in vitro by LDH level and MTT method respectively. Results Adhesion and invasion of enteropathogenic Escherichia coli to enterocyte-like cells was inhibited by high adhesiveness strain Lactobacillus reuteri JCM1081. In vitro, no significant changes of the morphology, structure and function of the HT-29 cells after being treated with Lactobacillus alone for 3 hours, especially cellular LDH level, viability and membrane permeability. Lactobacillus reuteri JCM1081 did not alter cell integrity and prevented the increase in permeability induced by enteropathogenic Escherichia coli infection. Conclusion Lactobacillus reuteri JCM1081 interact with intestinal epithelial cell receptor to competitively inhibit the adhesion and invasion of enteropathogenic Escherichia coli to HT-29 cells by incubation and enhance the integrity of the cells.

Objective: To explore the clinical value of transvaginal ultrasonography in diagnosis of ruptured ovarian cyst. Methods:Retrospective analysis the 46 cases of ruptured ovarian cyst diagnosis by transvginal ultrasonography in our hospital which confirmed by surgery and pathology. Results: In the among 46 cases, 39 cases were the corpus luteum cyst, 14 cases were the endometriotic cyst, were all confirmed by surgery and pathology, the diagnostic accurate rate of corpus luteum cyst is 92.3%, the rate of endometriotic cyst is 57.1%. Conclusion:Transvaginal ultrasonography is accurate, rapid and convenient, provides the reliable basis for the diagnose and different diagnose acute abdominal disease.

Objective To study the diagnostic value of high-sensitivity C-reactive protein (hs-CRP) and C-reactive protein (CRP) in patients with SARS.Methods The level of hs-CRP and CRP in patients with SARS,general bacterial pneumonia and the control are quantitatively detceted by automatically partielc enhanced immunoturbidimetric assay.Results The quantification level of -hs-CRP and CRP are 0 69?0 62mg/L and 4 4?0 9 mg/L in healthy control respectively,10 79?1 36 mg/L and 98 0?28 9 mg/L in bacterial pneumonia,3 16?3 72 mg/L and 11 0?9 6 mg/L in SARS.Conclusion The serum level of hs-CRP and CRP rese in patients with both SARS and bacterial pneumonia,especially in the latter,which is 2 4 and 7 9 times more than the former.This suggests that hs-CRP and CRP may be goog indicators to differentiate SARS with general bacterial pneumonia.

Objective To study on the relationship between insulin resistance and thyroid nodule in the patients of normal glucose metabolism. Methods The clinical data of 105 patients of normal glucose metabolism were analyzed. The patients were divided into nodules group (54 patients) and non- nodules group (51 patients). The age, sex, body mass index (BMI), fasting plasma glucose (FPG), postprandial 2 h blood glucose (2 h PG), fasting insulin (FINS), postprandial 2 h (2 h INS), fasting C peptide (FC-P), postprandial 2 h C peptide (2 h C-P), glycosylated hemoglobin (HbA1c), blood uric acid (BUA), homeostatic model assessment insulin resistance index (HOMA-IR) were compared between two groups. According the level of HOMA-IR, 105 patients were divided into different subgroups, the detection rate of thyroid nodules was compared. The influencing factors of thyroid nodules were analyzed by multi-factor Logistic regression analysis. Results The age and sex between two groups had no significant differences (P>0.05). The levels of BMI, BUA, HOMA-IR, FPG, FINS, 2 h INS, FC-P, 2 h C-P and HbA1c in nodules group were significantly higher than those in non-nodules group (P<0.05). The detection rate of thyroid nodules in HOMA-IR 3. 01- 4.00 group (12/14) and HOMA-IR > 4.00 group (20/20) was higher than that in HOMA-IR 0- 1.00 group (0), HOMA-IR 1.01- 2.00 group (39.5%, 17/43) and HOMA-IR 2.01-3.00 group (5/17), there were significant differences (P<0.01). Multi-factor Logistic regression analysis showed that the detection rate of thyroid nodules had positive correlation with levels of HOMA-IR, BUA and BMI (OR=0.278, 0.004 and 0.115, 95%CI 1.695-5.043, 1.001-1.015 and 1.046-1.644). The detection rate of thyroid nodules had no correlation with level of FPG (P>0.05). Conclusions The detection rate of thyroid nodules in HOMA-IR>3.00 patients is significantly higher. The insulin resistance, higher BMI and hyperuricemia are the independent risk factors of thyroid nodules.
