Objective To study the intervention effectiveness of intensive training in medical interns’occupational exposure protection.Methods Medical interns in seven colleges and universities in Wuhan between 2011 and 2015 were chosen and divided into control group (675 medical interns in 2011 - 2013,comprehensive training about healthcare-associated infection control was conducted for once before internship )and intervention group (682 medical interns in 2014 - 2015,hospital-department-tutor three steps of intensive training was conducted),the occurrence of occupational exposure and exposure knowledge awareness between two groups were compared. Results The awareness rate of knowledge about occupational exposure protection and the implementation rate of protective measures in intervention group were both higher than control group (all P <0.05).Incidence of occupa-tional exposure in intervention group was lower than control group (21 .70%[n=148]vs 65.33%[n=441 ],χ2 =262.91 ,P <0.01);percentage of interns who conducted active serological virus detection and intensified vaccination of hepatitis B virus were both higher than control group (14.66%[n=100]vs 2.96%[n=20];11 .73%[n=80]vs 2.67%[n=18],respectively).Occupational exposure before and after intervention occurred most frequently when interns were preparing medicine,occupational exposure reporting rate in intervention group was higher than control group (72.97%[108/148]vs 50.11 % [221/441 ],χ2 =52.78,P <0.01 ).Conclusion The intensive training of occupational exposure protection among medical interns can improve the awareness and skills of occupational protec-tion,and reduce the occurrence of occupational exposure.

This study examined the expression of cell adhesion molecule 1 (CADM1) in pancreatic cancer and the possible mechanism. The expression of CADM1 was detected by immunohistochemistry in tissues of pancreatic cancer, pancreatitis, and normal pancreas. The plasmid pcDNA3.1-Hygro(+)/CADM1 was transfected into PANC-1 cells (a pancreatic cancer cell line). The expression of CADM1 in the transfected cells was determined by RT-PCR and Western blotting. Cell growth was measured by the MTT method and cell apoptosis by flow cytometry. The results showed that CADM1 was weakly expressed in tissues of pancreatic cancer in contrast to its high expression in normal pancreatic and pancreatitis tissues. The expression level of CADM in pancreatic caner was intensely correlated with the differentiation degree, lymph node metastasis and TNM stages. The growth of CADM1-transfected PANC-1 cells was significantly suppressed in vitro by a G1 cell cycle arrest and apoptosis occurrence. It was concluded that re-expression of CADM1 inhibits the growth of pancreatic cancer cells and induces their apoptosis in vitro. As a tumor suppressor gene, CADM1 plays an important role in the occurrence, progression and metastasis of pancreatic cancer.

ObjectiveTo explore the expression of novel protein kinase C ε (PKCε) in normal prostate (NP) tissue, benign prostate hyperplasia(BPH), peficancerous (PC) tissue and prostate cancer (Pca), and study its correlation with the grade and stage of Pca.MethodsTen NP slides, ten BPH slides, ten PC slides and 43 Pca slides were collected from our hospital. These slides were routinely proceased and analyzed according to the requirement of immunohistochemical staining. Tumors were classified according to the 2002 TNM staging system. The grading system used in the study was based on the Gleason grade.ResultsWe was found that the expression of PKCεs in Pca (27/43) were significantly higher than those in NP(1/10), BPH (0/10) and PC (2/10) tissue, and the difference was statistically significant ( P ＜0.05 ). With regard to grade of prostate cancer, the expression of PKCε in Pca with Gleason score ≥8 group (12/13) was higher than the Gleason score 2 -4 group (4/10) and the Gleason score 5 -7 group (11/20). The difference was statistically significant (P ＜ 0.05 ). Moreover, the T3 and T4 stages had a more positive rate (10/12 & 9/10) than the T1 and T2 stages( 1/6 &7/15). There is statistically significant difference between early and advanced stage of prostate cancer ( P ＜ 0. 05 ). Furthermore, the positive expression of PKCε in prostatic carcinoma samples increased significantly in the metastasis group (9/10)compared to the non-metastasis group ( 18/33 ) ( P ＜ 0. 05 ), but the difference was not statistically significant between the concentration of prostate-specific antigen in blood serum ( P ＞ 0. 05 ).Conclusions PKCε is expressed in prostate cancer, and it correlates with the grade and stage of prostate cancer. PKCε may be related to the origin and the development of Pca, and it may be used as a prognostic factor for Pca.

Objective: To explore the relationship between myocardial ischemia and left ventricular diastolic function (LVDF) by fractional lfow reserve (FFR) evaluation in patients with coronary artery disease (CAD).
Methods: A total of 57 patients with chest pain were studied, the diagnosis of CAD was confirmed by coronary angiography, which indicated 50%-70%of coronary stenosis. All patients received FFR examination and they were divided into 2 groups:Experimental group, the patients with FFR<0.80, n=27 and Control group, the patients with FFR≥0.80, n=30. The basic condition and risk factors affecting LVDF were compared between 2 groups. Echocardiography was conducted for evaluating left ventricular end-diastolic dimension (LVEDD), left atrial dimension (LAD), left ventricular ejection fraction (LVEF) and E/e ' value in both groups.
Results: The patients’ gender, age, history of hypertension, diabetes, blood levels of cholesterol, TG, LDL-C, HDL-C and glucose were similar between 2 groups, P>0.05. Compared with Control group, the Experimental group had the increased LVEDD, LAD and E/e ' value and decreased LVEF, all P<0.05.
Conclusion: The impact of CAD on early diastolic function depends on functional myocardial ischemia in relevant patients.

OBJECTIVETo investigate the effects of angiotensin converting enzyme inhibitor (ACEI) captopril on Calpain-mediated cardiomyocytes apoptosis and cardiac function in diabetic rats.

METHODSThirty adult male SD rats were randomly divided into 3 groups (n = 10), normal control group (NC group), diabetes mellitus group (DM group)and captopril treated group (Cap group). Streptozocin (STZ) were used to make the model of diabetes mellitus, captopril was administrated by gavage at the dose of 50 mg/kg every day, while in NC group and DM group the same volume of normal saline was administrated. Twelve weeks later, left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVDEP), maximal rise rate of left ventricular pressure (+ dp/dtmax) and maximal fall rate of left ventricular pressure (- dp/dtmax) were detected; Western blot was used to detect the expression of Calpain-1 Calpain-2, Bcl-2, Bax and total Caspase3 protein; apoptosis index (AI) were assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL).

RESULTSCompared with NC group, LVDEP was significantly higher; LVSP, + dp/dtmax and - dp/dtmax were significantly decreased (P < 0.05); Bcl-2 protein expression was decreased; the expression of Calpain-1, Calpain-2, Bax and total Caspase3 protein were increased; the value of AI was significantly increased. Compared with DM group, LVDEP was significantly lower; LVSP, + dp/dtmax and - dp/dtmax were significantly increased (P < 0.05); Bcl-2 protein expression was increased, the expression of Calpain-1, Calpain-2, Bax and total Caspase3 protein were decreased; the value of AI was significantly decreased (P < 0.05).

CONCLUSIONCaptopril can protect diabetic myocardial structure through inhibiting activation of Calpain-1 and Calpain-2, up-regulating the expression of Bcl-2, down-regulating the expression of Bax to inhibit Caspase3 dependent apoptosis, thereby improving the ventricular function and myocardial structure.
