Objective:To analyze and compare pharmacology cognizing between five-year and three-year systems students in medicine to provide materials for teaching innovation.Method:To gather feedbacks from the students and to analyze and induce the cases by EXCEL software.Results:The effectiveness of medicament is the focus.But five-year and three-year systems students concern different problems.57.1% questions raised by three-year system students are about the effectiveness and the effective factors of medicament,while 53.2% by five-year system students are about the effectiveness and the mechanism of medicament.Conclusion: There have been certain differences of pharmacology cognizing between five-year and three-year systems students.

Objective To make recommendations on the development of private hospitals,by means of investigation and analysis of their business operations.Methods Quantitative and descriptive analysis were used to study business operation data from 2011 to 2013 of the 172 private hospitals,in order to learn their present status and development trends.These data were compared with public hospitals in average to identify problems.Results The revenue and expenditure of theses private hospitals increased at a fast pace,with a revenue growth rate of 22.0% and an expenditure growth rate of 15.7% in 2013.Number of visits gradually improved,with an increase of 12.9%.But the rate of bed occupancy was only 68.1%,lower than the average of public hospitals.Conclusions In view of the low resource utilization,the authors recommend such hospitals to improve hospital management systems,and uphold the integrity of business,so as to compete with public hospitals differentially.

Objective　To assess the CT manifestations and diagnostic value in the pancreatic tuberculosis(PTB)with review of the literatures. Methods　All cases of PTB proved by surgery or biopsy were examined with plain and enhanced CT scans. Results　The CT findings in one case with multiple-nodular type of PTB were diffuse enlargement of the pancreas with multiple, nodular, and low-density lesions; The nodular lesions had peripheral enhancement. 7 cases of local type of PTB encroached on pancreatic head. 4 cases showed local soft tissue masses with multiple flecked calcifications in 2 cases and mild enhancement in one case; Cystic masses was found in 2 cases, with mural calcification in 1 case and multiloculated cystic mass in 1 case, respectively; Massive pancreatic head calcification was demonstrated in one case. In these 8 cases of PTB, the lesion extended out of pancreas in 4 cases, including abdominal tuberculous lymph nodes, tuberculous peritonitis, and hepatosplenic tuberculosis. Conclusion　CT findings of PTB were various but had some characteristics. Pancreatic masses with multiple flecked calcification or mild enhancement could suggest the diagnosis. Abdominal tuberculosis accompanied with the pancreatic lesion, especially tuberculous lymph nodes, was highly suggestive of the diagnosis of PTB.

Objective To investigate the correlation between tetramine poisoning and hypocalcemia in children.Methods According to different severe cases grade,tetramine poisoning children were divided into critical group(70-90 score),extremely critical group(

Objective To investigate the auxiliary effects of huaier granule on hepatoeellular carcinoma (HCC)patients after liver transplantation.Methods Sixty HCC patients who had undergone liver transplantation from Julv 2004 to June 2006 and met the standard of UCSF were involved in this study.All patients were divided into huaier granule group(n=20),chemotherapy group(n=15),huaier granule+chemotherapy group (n=15)and control group(n=10).The white blood cell count,liver function,cell immunity and immunologieal reiection were detected.The 1-year tumor recurrence rate wag calculated.Results The white blood cell counts in chemotherapy group 1,3,and 6 months after treatment were significantly lower than that before treatment (F=62.053,58.472,49.807,P＜0.05).The changes of white blood cell counts of the other 3 groups before and aftertreatment were small.The difference on the white blood cell counts of the 4 groups had no statistical 8ignincanee(F=102.361,113.412,87.572,P＜0.05).The NK activity,CD4+/CD8+ ratio,IL-2 level in huaier granule group and huaier granule+chemotherapy group 1,3,6 months after treatment were significantly higher than those before treatment,and were significantly higher than those in chemotherapy group and control group(P＜0.05).No immunological rejection occurred in all the groups.Two patients in each group had recurrence and metastasis of HCC within 1 year after the treatment.and the incidence in control group was higher than the other 3 groups(P＜0.05). Conclusions Humer granule can increase the white blood cell count which is decreased after chemotherapy,impmve cellular immunity,and effectively suppress the recurrence and metastasis of HCC at the first year after operation.

Background Cardiac mast cell-derived chymase is involved in myocardial fibrosis,but the underlying mechanisms remain unclear. Objective To investigate the effect of chymase on the collagen synthesis and its relationship with transforming growth factor-?1 (TGF-?1)/Smad pathway in rat cardiac fibroblasts (CFs). Methods CFs,from neonatal SD rats,were isolated by trypsinization. The collagen synthesis of CFs was determined by 3H-proline incorporation. The protein expressions of TGF-?1,phosphorylated Smad2/3 (P-Smad2/3) and total Smad2/3 were determined by immunoblotting in CFs. Results Chymase (15,30 and 60 ?g/L) increased the 3H-proline incorporation in a concentration-dependent manner. 30 ?g/L chymase stimulation increased the protein expressions of TGF-?1 and P-Smad2/3 in a time-dependently,while little effect on Smad2/3 protein expression was found. The stimulatory effect of chymase on 3H-proline incorporation elicited by 30 ?g/L chymase was blocked in the presence of TGF-?1 antibody or staurosporine,a P-Smad2/3 inhibitor. Conclusion Chymase promotes collagen synthesis of rat CFs,TGF-?1/Smad might be involved into the signal pathway.

Case based learning ( CBL ) teaching method was applied to the experiment group in radiology internship teaching,and conventional teaching in control group.Two mentors would evaluate and score their radiological case analysis.The aim of this research was to explore the application and effect of case-based learning ( CBL ) teaching method in radiology internship teaching.

Objective To systematically review the effect of telephone intervention on colostomy patients.Methods The randomized controlled trials (RCTs) of telephone intervention on colostomy patients were searched in CBM,VIP,CNKI and Wanfang database and analyzed by RevMan5.2 software.Results Nine RCTs were included.Results of systematic evaluation showed that there were statistical difference in the self-care status,obeying doctors' order,satisfaction degree,self management ability,quality of life.Conclusions The effect of telephone intervention on colostomy patients was better than that of the traditional intervention.

Objective To observe the abnormality on behavioral ability of transgenic mice for HRX-EEN fusion gene.Methods Transgenic mice for HRX-EEN fusion gene(transgenic group,n=12)and C57/BL mice(control group,n=12)were tested in hidden platform training(day 1 to day 4)and probe trial testing(day 5)in Morris water maze in which ability of spatial learning and retention was assessed.Results In hidden platform training,the latencies of transgenic group were longer than those in control group,and significant differences were observed between the two groups for day 2,3 and 4(P
