Objective: To observe the atrial expression of angiotensin II receptor type 1 (AT1R) and α7-nicotinic acetylcholine receptor(α7nAChR) during the development of heart failure in rats. Methods: Male SD rats were randomly divided into 4 groups. Abdominal aorta coarctation (AAC) was used to prepare heart failure model. Expression of AT1R and α7nAChR was determined by Western blotting analysis at 4,8,12, and 16 weeks after AAC in all the groups. Results: Compared with the control group, expression of AT1R and α7nAChR in AAC group was not significantly different at all the 4 time points after AAC. Conclusion: Our findings suggest that atrial AT1R and α7nAChR may not be involved in the early stage pathological process of AAC-induced heart failure.

Objective To investigate the effect of estrogen on gliosis, synaptic proliferation and reorganization in hippocampus of rats with chronic epilepsy induced by pentylenetetrazol (PTZ). Methods Thirty-two Wistar rats were randomly divided into normal control group, PTZ kindling epilepsy group, estrogen+PTZ group and estrogen +Tamoxifen (mixed estrogen antagonist)+PTZ group. The PTZ kindling epilepsy group was intraperitoneally injected with 35 mg/kg PTZ once a day, then the behavior of the rats in one hour was observed. The estrogen interfered group was intramuscluarly injected of 0.6 ?g/kg ?-estradiol 6 h before PTZ injection, 1/3 d. The estrogen+Tamoxifen interfered group was injected of Tamoxifen into lateral cerebral ventricle 1 h before estrogen injection. If the severe epileptic seizures occurred three times, the rats were ready for detecting the expression of filial fibrillary acidic protein (GFAP) and synaptophysin (P38) by immunohistochemical technique. Results Epileptic seizure occoured earlier and more severely in most rats of estrogen interfered group than no estrogen interfered group. Rats in all model groups were found more astrocyte proliferation and positive synaptophysin staining, especially in the CA2, CA3 and hilar areas of dentate gyrus (DG) of hippocampus than control group. Estrogen+Tamoxifen interfered group showed significant difference as compared with other groups (P

Evidence-based medicine emphasizes making project of diagnosis and therapy on the basis of the most objective research results. The current condition in which domestic medicine is dominant in hepatobiliary surgery and teaching needs to be changed urgently. The procedure of application of evidence-based medicine in teaching of hepatobiliary surgery is explained by an actual example. Evidence-based medicine plays an important role in teaching and quick progress in all of the hepatobiliary surgery.

Objective To observe the effects of intensive insulin therapy on IL-10 level and NF-ΚB activity in peripheral blood mononuclear cells in patients undergoing cardiopulmonary bypass.Methods The non-diabetic patients undergoing cardiopulmonary bypass in our department were selected and assigned to intensive therapy group (group A,n=40) and received strict glycemic control after the initiation of surgery.And those who undergoing cardiac surgery but without strict glycemic control were assigned to routine therapy group (group B,n=40) as controls.The blood glucose in group A was maintained at 4.4～8.3mmol/L,whereas the glucose in group B was below 11.lmmol/L.The concentration of serum IL-10 and NF-ΚB activity in peripheral blood mononuclear cells was measured at different time points.Results There were no significant differences in general data between two groups.The concentration of IL-10 in group B was significantly lower than that in group A(P<0.05).compared with group B,strict glycemic control markedly suppressed NF-KB activation (P<0.05).Conclusion Intensive insulin therapy could reduce the activity of NF-ΚB and then reduce the expression of IL-10.Strict glycemic control could significantly mitigate the systemic inflammatory response.

Objective To summarize the effect of tension-free hernioplasty for inguinal hernia .Methods Retrospective analysis of 619 cases of adult inguinal hernia underwent tension-free hernioplasty clinical data , curative effect and complications were observed .Results Patients could all get up 1 day after operation .Incisional pain was disappeared within 1-2days.Postoperative scrotal hematoma was found with 3 cases,no postoperative incision infec-tion,rejection.574 cases were followed up for 3 months to 4 years, there was no recurrence .Conclusion Adopting the method of Tension-free herniorrhaphy in treatment for inguinal hernia has the advantages of less trauma , faster postoperative recovery ,less complications and low recurrence rate etc .

Objective To investigate the association between peripheral monocyte CD36 expression and rheum-atoid arthritis (RA).Methods A total of 108 patients with RA and 108 healthy individuals were included between 2014 and 2015.Disease Activity Score (DAS)28-erythrocyte sedimentation rate (ESR) and DAS28-C reactive protein (CRP) were used to estimate disease activity in patients with RA,and monocyte CD36 fluorescence intensity was determined by using flow cytometry.Student's t test or Mann-Whitney U test was used to compare the differences between the two groups.The categorical data was compared using x2 test.Correlations between variables were analyzed with Spearman correlation,Logistic regression analysis was used to identify risk factors associated with RA,we used receiver operating characteristic (ROC) curve to estimate the performance of relevant variables for RA.Results Low density lipoprotein cholesterin (LDL-C) [(2.8±0.8) mmol/L,(2.6±0.6) mmol/L,t=-2.046,P=0.042],ESR[25.5(18.00,40.00) mm/1 h,10.00(4.60,10.00) mm/1 h,Z=-12.786,P＜0.01],CRP [15.9 (6.71,25.43) mg/L,2.28 (1.63,4.60) mg/L,Z=-7.980,P＜0.01] and monocyte CD36 expression [(0.44±0.22)×109/L,(081 ±0.26)×109/L,t=1 1.159,P＜0.01] was statistically different between the two groups.Of note,monocyte CD36 fluorescence intensity was negatively correlated with disease activity in patients with moderate and severe disease (r=-0.146,P=0.036;r=-0.259,P=0.007).In stepwise Logistic regression analysis,monocyte CD36 fluorescence intensity was independently associated with RA [OR=0.803,P=0.002,95％CI (0.791,0.820)].ROC curve analysis showed a significant performance with area under curve of 0.855 [95％CI (0.807,0.904);P＜0.01],the sensitivity and specificity were 80.6％ and 73.1％,respectively,the cutoff values was 0.570.Conclusion Monocyte CD36 fluorescence intensity was independently associated with RA in stepwise Logistic regression analysis.A correlation between monocyte CD36 fluorescence intensity and DAS28-CRP,DAS28-ESR was observed in RA patients.

The writing of vocational college thesis is the maln way to test whether the students are able to analyze and solve practical problems with the professional knowledge and skills they've learnt, as well as improve the capability of production and practice. This paper analyzes the present situation of the thesis written by higher vocational college students majoring in pharmaceutical sci-ences, and figures out the four kinds of evaluation standards about graduation thesis for students in various pharmaceutical fields with different problems. The four kinds of evaluation standards includes key point analysis on Standard Operation Procedure (SOP), planning strategy for pharmaceutical mar-keting, investigation of rational use of drugs in hospitals and subject research. The author puts forward the solving method for the problem, and formulate the evaluation requirements.
