1.Preliminary practice of clinical scenario teaching mode
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.
2.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.

OBJECTIVE: To investigate the effect of Salvia Miltiorrhiza injection (SMI) on peritoneal dialysis solution (PDS) induced injuries of peritoneal structure and function in a rat model, and to observe the relationship between the failure of peritoneal dialysis and expressions of aquaporin-1 (AQP-1) and zonula occluden-1 (ZO-1) in peritoneal tissues. METHODS: Fifty-six SD rats were randomly divided into normal control group, 1.5% PDS group, 4.25% PDS group, 1.5%PDS+1% SMI group, 1.5%PDS+2% SMI group, 4.25% PDS+1% SMI group and 4.25% PDS+2% SMI group. Two-hour peritoneal dialysis test was performed in rats in different groups by intraperitoneal injection for 8-week. Then rats were killed on the 8th week, and the bloods and peritoneal tissues were gathered. The rate of ultrafiltration, clearance rates of urea nitrogen, creatinine and glucose of peritoneum and content of total protein in PDS were detected. Peritoneal membrane histology was evaluated by light microscopy and transmission electron microscopy. Expressions of ZO-1 and AQP-1 proteins in peritoneal tissues were detected by immunohistochemical method, and AQP-1 protein expression was also detected by Western blotting technique. RESULTS: Compared with normal control group, using of 1.5% PDS and 4.25% PDS caused the changes of structure and function in peritoneum, such as pathological change of peritoneum, decreasing of the rate of ultrafiltration (P<0.05), clearance rates of creatinine and glucose (P<0.01) and the expression of ZO-1 protein (P<0.05), and increasing of the expression of AQP-1 protein (P<0.05). Compared with the simple PDS groups, the pathological damage of peritoneum was lessened and the rate of ultrafiltration and clearance rates of creatinine and glucose were increased in the 1.5% PDS+2% SMI group and 1.5% PDS+2% SMI group. Expression of AQP-1 protein was decreased by 1.5% PDS+2% SMI as compared with 1.5% PDS (P<0.05).[JP] CONCLUSION: SMI can relieve the injuries of function and structure of peritoneum by down-regulating the expression of AQP-1 protein.

Aim To explore the role of endoplasmic reticulum stress (EPR) in high fatty acid induced injury in cardiomyocytes.Methods Cardiomyocytes were exposed to different concentrations of palmitic acid (0, 0.1, 0.2, 0.4 mmol·L-1) for 24 h and different time points of high palmitic acid (0.2 mmol·L-1) (12, 24, 48 h).Cell viability was measured by CCK8, and the protein expressions of EPR such as GRP78, CHOP, PERKphos, IRE1phos, ATF6 and apoptosis related proteins such as Bcl-2 and Bax were determined by Western blot.Results When the cells were stimulated with palmitic acid (0.1~0.4 mmol·L-1) for 24 h, the cell proliferation rates of 0.2 and 0.4 mmol·L-1 groups were significantly decreased.Cardiomyocytes exposured to high palmitic acid (0.2 mmol·L-1) for 24 h showed an increase in theexpression of EPR related proteins (GRP78, CHOP, PERKphos, IRE1phos and ATF6) and Bax(P<0.05), while Bcl-2 expression was significantly reduced.Pretreatmented with EPR inhibitor pravastatin(10 mol·L-1) significantly increased high palmitic acid induced Bcl-2 expression (P<0.05) and significantly decreased high palmitic acid induced Bax expression (P<0.05).Conclusion Activated EPR might play an important role in treatment of high fatty acid induced myocardial injury.

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.

Chinese Journal of Practical Nursing 2015;(32):2435-2438
Objective To evaluate the effects of aerobic combined strength and balance exercise on cognitive function and satisfaction in patients with cognitive impairment no dementia. Methods Four hundred and twenty patients with cognitive impairment no dementia were divided into control group (200 cases) and experimental group (220 cases) by random digits table method. The control group received general health education and rehabilitation training. The experimental group received aerobic combined strength and balance exercise. The patients were assessed with Montreal Cognitive Assessment (MoCA) to evaluate their cognition before training, as well as after training. And the patients′satisfaction with the questionnaire was evaluated. Results The total scores of MoCA, scores of name, attention, language, memory and directionafter training were (23.47 ±2.38), (2.77 ±0.42), (5.09 ±0.86), (2.50 ±0.65), (3.42 ±0.68), (5.03 ± 0.10) points in the experimental group, and (21.20±2.55), (2.31±0.76), (4.71±1.10), (2.35±0.70), (2.23±0.81), (4.48±0.96) points in the control group, and there were significant differences, P<0.05. There were no significant differences in the space and abstract thinking between experimental group and control group:(3.61±0.91) points vs. (3.45±1.09) points, (1.83±0.76 ) points vs. (1.72±0.52) points, P>0.05. The scores of satisfaction in the experimental group was significantly higher than that in the control group:(49.33 ±1.57) points vs. ( 48.20 ±2.14) points, P<0.01.
