AIM:To study the relationship between the genetic polymorphism of CYP3A5 gene and the blood concentration/dose(C/D) ratio of cyclosporine combined with calcium channel blockers(CCBs) in renal transplant patients.METHODS:Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) analysis was applied to determine the genotype of CYP3A5 in 69 renal transplant patients.The blood concentration/dose(C/D) ratio of cyclosporine was compared in patients coadministrated of CCBs with different genetic polymorphism of CYP3A5.RESULTS:The cases of genotype of CYP3A51/1,CYP3A51/3 and CYP3A53/3 were 8,23 and 38,respectively.The mutation rate of CYP3A53 in renal transplant patients was 71.74%.The CsA C/D ratio of patients of CYP3A51/1 and CYP3A51/3 were 1.73 and 2.43 times higher than that in patients of CYP3A53/3.The CsA C/D ratio of patients(CYP3A51/1,CYP3A51/3) combined with CCBs had been obviously elevated(19.90?7.66 vs 36.01?8.18,34.33?7.87 vs 46.16?9.63 ng?mL-1 per mg?kg-1;P

Objective To explore the difference between the results of the cross-disciplinary joint teaching method and the traditional teaching method in medical humanity courses.Method 128 students in one military medical university were selected to be randomly assigned to the study group and the control group,using the cross-disciplinary joint teaching mode (study group,n=64) and traditional teaching mode (control group,n=64) in medical humanity courses.For the joint teaching mode,we compiled the teaching materials of medical humanities,formed the teaching team and organized the academic communication after class by social media.After all courses were finished,the subject cognition and approval of whole students were evaluated by the unified arranged examination and questionnaire.Then the data was processed by SPSS 18.0.Results On the aspect of subject cognition,the total scores of the study group were higher than control group in health law [(76.2 ± 3.34) vs.(72.5 ± 4.76);t=3.32,P=0.000] and medical ethics [(75.3 ±2.93) vs.(68.3 ± 3.10);t=4.01,P=0.000].On the aspect of subject approval,the recognition of the students of the study group in these three subjects were more than those of the control group except the selfevaluation of medical psychology (P=0.000).Conclusion The application of cross-disciplinary joint teaching method on medical humanity courses contributes evidently to the promotion of the medical humanity quality of clinical medical students.To implement this model,however,multi-sided resources are needed for colleges to coor-dinate,for perfect results require more practical exploration.

Prostatic stromal fibroblasts were obtained from human fetal prostate and the effect of androgen (DHT) , estrogen (E2) , and human prostatic growth factor (hPGF) on the proliferation of the cultured fibroblasts was studied. The results showed that: 1) DHT and hPGF had significant stimulatory effect on proliferation of the cells; DHT had a delayed stimulatory effect, while hPGF had an immediate one. 2) E2 had no effect on proliferation of the cultured fibroblasts. 3) Used jointly, E2 and DHT had no stimulating effect on the proliferation of the fibroblasts. The results suggest that the effect of DHT on the proliferation of human prostatic stromal fibroblasts may be indirect. It possibly regulates the growth of prostate by stimulating autocrine or paracrine function of the prostatic cells.

Objective To investigate re-innervation in the neovaginal mucosa of patients underwent sigmoid colon vaginoplasty in treatment of Mayer-Rokitansky-Kistner-Hauser Syndrome (MRKHS).Methods Biopsies in the upper third of the posterior neovagina were taken in 20 patients treated by sigmoid colon vaginoplasty at 1, 2 and 3 years after surgery, respectively. Protein gene product 9. 5 ( PGP 9. 5 ),vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) were detected by immunohistochemical method and compared with those in intact sigmoid colon mucosa. Results ( 1 ) Density of nerve fiber:abundant distribution of PGP 9. 5 nerve fibers were observed in the mucosal muscle layer, submucosa, and smooth muscle layer of the neovagina. The nerve fibers of VIP and NPY immunoreactivity were mainly distributed around blood vessels and in the smooth muscles. In the neovagina, the density of nerve fibers of PGP 9. 5 of 17 ± 6 were much more than VIP of 2. 9 ± 1.0 and NPY of 2. 5 ± 0. 8 significantly ( P ＜ 0. 05 ).( 2 ) Expression of PGP 9. 5 in neovagina: at 1 year after surgery, PGP 9. 5 positive expression of 14 ± 4 was significantly lower in the neovagina than 28 ± 7 in the intact sigmoid colon( P ＜ 0. 05 ). However, after 2 to 3 years, its expression displayed an upgrade tendency in the neovagina and was significantly higher at the 3 year postoperatively than that at the 1 years postoperatively ( 22 ± 7 vs. 14 ± 4, P ＜ 0. 05 ). The changes were much more obvious in submucosa. (3) The expression of VIP and NPY in neovagina: at 1 year after surgery, VIP and NPY positive nerve fibers were also decreased in the neovagina when compared with those in the intact sigmoid colon ( 2. 3 ± 0. 7 vs. 5.3 ± 1.4, P ＜ 0. 05; 2.5 ± 1. 1 vs. 5.5 ± 1.1, P ＜ 0. 05 ) . At 2 to 3 years after surgery, the positive VIP fiber showed initially decreased and subsequently increased tendency. The density of VIP of 3.7 ± 0. 7 in the neovagina at 3 years postoperatively was higher than 2. 3 ±0. 7 at 1 years postoperatively (P ＜ 0. 05 ). No significant up-regulation was observed in NPY-positive expression in the neovagina within 3 years after operation. Conclusions Distribution of sensory PGP 9. 5,VIP and NPY immunoreactive nerve fibers was similar to the pattern observed within the intact sigmoid colon wall. The number of nerve fibers in the neovagina decreased after surgery and then increased subsequently within 3 years after surgery.

quamous metaplasia occurred, the expression of occludin and ZO-1 in cells were similar to those in control group, which might play a role in the defense function of neovaginal mucosa.

Objective To discuss the classification and treatment of the degloving hand.Methods All 68 degloving hand treated between January, 2005 and December, 2014 in our department were reviewed.The cases were divided into three types according to the extent of the injury.Type Ⅰ the degloving tissue had enough blood supply which was debrided and stitched.Type Ⅱ the degloving tissue had less or no blood supply which was revascularized with replantation or vein anastomosis, some degloving palm or dorsum resurfaced the wound by the degloving skin graft.Type Ⅲ the degloving tissue had no blood supply or severely damaged,the tissue defect should be resurfaced with other tissue reconstruction.Type Ⅱ and Ⅲ were further divided into subtype A, B and C depending on the degloving scope and location, each subtype has its own surgical procedure.Results The total survival rate was 83.8％.The survival rate decreased with the increasing extent of the injury and the increasing degloving scope.Conclusion Classification of the hand degloving injuries depending on the extent of the injury, the degloving scope and location is useful for the assessment of injury and the selection of proper operation procedures.

Objective To investigate the detection rate of abnormal cardiovascular and metabolic indicators in health check-up populations,and provide evidence for early screening and health interventions for cardiovascular and metabolic diseases.Methods A total of 5578 adults (male 3404 and female 2174) were recruited from a medical institution in Beijing in 2008 and 2010.Cardiovascular and metabolic indicators,including blood pressure,lipid profile and fasting plasma glucose,were tested at baseline and 2 years.Paired t test or paired rank sum test was used for data analysis.Results Detection rate of abnormal blood pressure in 2010 was lower than that in 2008; however,rates of abnormal total cholesterol,low-density lipoprotein cholesterol and fasting plasma glucose were higher in 2010 than in 2008 (t values were 5.378,13.885,3.210,10.401 and 4.355,respectively; all P ＜ 0.05).High-density lipoprotein cholesterol and triglyceride showed no statistically significant difference between 2008 and 2010 (t values were 1.204 and -0.012,respectively; both P ＞ 0.05).Conclusion We have been observing a dynamic change in abnormal cardiovascular and metabolic indicators,based on which effective interventions could be taken to reduce the risk of cardiovascular diseases.

Objective To understand the epidemical patterns of schistosomiasis in Guichi District of Chizhou City，Anhui Province，in order to provide the reference for schistosomiasis control. Methods The annual data of schistosomiasis endemic situation in Guichi District from 1991 to 2011 were collected. The descriptive analysis was first conducted to describe the changes of schistosomiasis in local residents and the status of Oncomelania hupensis. An autoregressive integrated moving average （ARIMA）model was applied to fit and predict the tendency of schistosomiasis incidence in this region. Results The humanmorbidity increased with the increasing of the areas with snail habitats（P < 0.05），and four peaks（in 1992，1995，2005，2008）were detected. The difference of the area with snails among different types of snail habitats was statistically significant（F = 256.79，P < 0.05）. ARIMA（1，1，1）was determined to be the optimal model for analyzing the morbidity of schistosomiasis，and the short⁃term forecast of the morbidity in Guichi District from 2012 to 2015 showed that the predicted values were 0.017%，0.007%，0.012%，and 0.010%，respectively. Conclusions The endemic situation of schistosomiasis in Guichi District is controlled relatively well in the past two decades. However，the surveillance in the lake and marshland regions should be strengthened continuously to prevent the rebounding of the schistosomiasis endemic situation.
