Objective To investigate the relationship of vitamin D with the intestinal development and study the expression of vitamin D receptor (VDR) in the duodenum of C57BL/6 mice at different developmental stages.Methods Quantitative PCR (qPCR),histology using H&E staining and immunofluorescence staining,and Western blotting (WB) were performed to elucidate the expression of VDR in mice intestine at different growth and developmental stages.Results The peak of VDR mRNA expression reached on 21 d.The pathological result showed that VDR mainly distributed in the cytoplasm of epithelial cells and smooth muscle cells in the mouse duodenum.WB result indicated that there was no nuclear translocation of VDR protein in the mouse duodenum.Conclusions This study demonstrates the regularity of expression of VDR in the mouse duodenum during its development,and contributes to understanding the function of VDR in the intestines.

Nowadays, ceremony education, as a specific education method, is becoming increasingly popular in medical humanistic education.It is a truth generally acknowledged that the importance of ceremony education is located at its extensive scope and plasticity.The cultivation of medical students' human-oriented spirit, strengthening their career identity and enhancing their ideological moralitycan be processed by ceremony education, in which much attention is attached to its four features, identity recognition, emotion polymerization, spirit conduction and cultural inheritance.However, there still exist some problems to be solved in the practice of ceremony education such as overformalization, insufficient individuation and systematization.That is what we mean to discuss in this paper.

Aim To explore the effect of Osthole (Ost)on the right ventricle remodeling in monocrot-alinetreated rats and the possible mechanism.Meth-ods ♂ SD rats were randomly divided into normal control group,model group,low dose of Ost treatment group (10 mg·kg -1 )and high dose of Ost treatment group (20 mg·kg -1 ).All rats were given a single dose of MCT 50 mg·kg -1 subcutaneously to establish the right ventricle remodeling except normal control group.Then the rats in Ost treatment group were ga-vaged once daily.After 28 days of administration,the right ventricle(RV)and left ventricle plus septum(LV+SEP)were weighed separately.RV hypertrophy in-dex (RVHI)were measured by the relative weight rati-o of RV to LV +SEP.The morphological changes of right ventricle were executed by HE staining.The pro-tein expression of PPARαand PPARγwere detected by Western blot.Results Compared with the control group,RVHI was increased obviously (P <0.05 ), myocardial hypertrophy and structure disorders were observed in model group.The protein expression of PPARαand PPARγwere down-regulated significantly in model group (P <0.05).Compared with the model group,the value of RVHI (P <0.05),myocardial hy-pertrophy,structure disorders were improved signifi-cantly in Ost treatment group.The protein expression of PPARαand PPARγwere up-regulated in Ost treat-ment group (P <0.05).Conclusion Ost can attenu-ate the right ventricle remodeling induced by MCT in rats,which may be related to up-regulating the expres-sion of PPARαand PPARγ.

Objective To explore the effect of transabdominal posterior rectopexy with resection of the partial rectosigmoid colon on adult rectal prolapse.Methods During the 2006 to 2011,transabdominal posterior rectopexy with resection of the partial rectosigmoid colon was performed on 6 selected adult patients with complete rectal prolapse.Results All patients were cured,the median length of hospital stay was 13.7 days.Followed up for 3-61 months,there was no recurrent case.Conclusions The operation offers a safe and effective alternative to other more complex procedures for the treatment of adult rectal prolapse.The procedure can not only treat the rectosigmoid disease,but also improve the rectosigmoid disease,improve the function of bowel and reduce the recurrence rate.

Aim To investigate the effect of icariin ( ICA) on renal interstitial fibrosis in SHR and explore its mechanism. Methods Fourteen male SHR of 13-week-old were randomly divided into model group( n=7 ) and ICA group ( n=7 ) , and WKY as control group (n=7). One week after adaptive breeding,the rats in the ICA group were given ICA 40 mg·kg-1,ig,bid to 26-week-old. The other rats in the model group and control group were given the same amount of normal sa-line. Then, the morphological changes of the kidney were observed by HE and Masson staining,respective-ly. The contents of plasma aldosterone andⅢcollagen were measured by double antibody sandwich method. The mRNA expressions of TGF-β1 , Smad2 , CTGF and FN were examined by real time RT-PCR. Results Compared with the normal control group, the kidney structures of model group were disordered,the mesang-ial matrix and the tubular interstitial fibrosis were in-creased. The contents of plasma aldosterone and Ⅲcollagen were increased in model group ( P <0. 01 ) . And the mRNA expressions of TGF-β1 , Smad2 , CTGF and FN in kidney tissues were up-regulated in model group( P <0. 01 or P <0. 05 ) . Compared with the model group,the kidney structures were improved and the contents of plasma aldosterone and Ⅲ collagen were reduced, as well as the mRNA expressions of TGF-β1,Smad2,CTGF and FN in kidney tissues were down-regulated(P<0. 01 or P<0. 05)in ICA group. Conclusion ICA may have anti-renal interstitial fi-brosis effect on SHR,and the mechanism might be re-lated to the reduced plasma aldosterone levels and the down-regulated expression of TGF-β1 and Smad2 .
