This study examined the effects of ursolic acid (UA) on the proliferation and apoptosis of a human ovarian cancer cell line, CAOV3. The CAOV3 cells were cultured in the RPMI 1640 media and treated with different concentrations of UA (0, 10, 20, 40 mumol/L). The proliferation rate of the CAOV3 cells was determined by MTT assay. The apoptosis rate was measured by flow cytometry. ERK activity was detected by immunoprecipitation and the expressions of p-ERK1/2, MKP-1, Bax and Bcl-2 by Western blotting. The results showed that the proliferation rate was significantly decreased in the cells treated with UA as compared with that in the non-treated cells (P<0.05). The intracellular ERK activity and p-ERK1/2 expression were also reduced in the UA-treated cells, while the MKP-1 expression was elevated. Moreover, the apoptosis was found in the CAOV3 cells exposed to UA; the Bax expression was increased and the Bcl-2 expression decreased. The apoptosis rate in the UA-treated cells was much higher than that in the non-treated cells (P<0.05). It is concluded that UA can inhibit the proliferation of CAOV3 cells by suppressing the ERK activity and the expression of p-ERK1/2. And it can also induce the apoptosis of the CAOV3 cells by up-regulating the Bax expression and down-regulating the Bcl-2 expression.

Objective To investigate risk factors for early postoperative complications after pancreaticoduodenectomy(PD).Methods Clinical data of 221 patients undergoing PD in our hospital between September 2005 and January 2009 were collected and reviewed retrospectively,the risk factors in relation to early postoperative complications were analyzed with SPSS 15.0 software.Results The incidence of early postoperative complications was 17.6％.Univariate analysis showed that age ( ≥65 years),preoperative total serum bilirubin level ( ≥ 171 μmol/L),preoperative serum albumin level ( ≤30 g/L),intraoperative blood transfusion ( ≥ 1000 ml),operation time ( ≥5 h) were the relative risk factors,Logistic regression analysis revealed that age (≥ 65 years),preoperative serum albumin level ( ≤30 g/L),intraoperative blood transfusion ( ≥ 1000 ml),operation time ( ≥5 h) were the independent risk factors for early complications.Conclusions The risk of postoperative complications after PD is still high,so the dicision to perform a PD should be strictly balanced against its risk.For older or poor risk patients,preoperative management should be enhanced.The set up of surgical team may help standardize operation procedures control intraoperative bleeding,therefore decrease the incidence of postoperative complications after PD.

Objective To analyze and summarize the clinical-pathological features,immunophenotype and prognosis of the lymphoepithelioma-like gastric carcinoma (LELGC).Methods The clinical,radiographic and histological data of four patients with LELGC were retrospectively analyzed.The expression of cytokeratin (CK),CD20,CD3,CD4,CD8,E-cadherin,β-catenin,bcl-2,p16,p53,p63,c-erbB-2,cyclin D1,Ki67 and DNA methyl-transferase 1 (DNMT1) in tumor was detected by Epstein-Barr virus-encoded small RNA (EBER) in situ hybridization and immunohistochemical methods.Results The size of four tumor was 1.8 cm× 1.6 cm,1.5 cm× 2.0 cm,2.5 cm× 2.0 cm and 4.0 cm× 2.5 cm.Under light microscope,tumor cells appeared like cords,small lumps or scattered single infiltration with vacuolized nucleus; clear nucleoli and obvious interstitial lymphocytic infiltration.The results of immunohistochemical examination indicated that in four tumors CK was positive in membrane of all the tumor cells,while EBER was positive in all cell nucleus.The number of lymphocytes with CD3 positive was over those with CD20 positive,which was mainly CD8 positive lymphocytes.The percentage of E cadherin and β-catenin positive in the cell membrane of four tumors was between 10 ％ and 90 ％,and two cases with β-catenin positive in cytoplasm.The expressions of DNMT1,cyclin D1 and bcl-2 were all positive,while p16 and c-erbB-2 were all negative.The expression of p63 was positive in only one case,and p53 was negative in one case.The percentage of Ki67 positive was 40％,15％,60％ and 40％,respectively.Conclusions LELGC is a rare neoplasm with better prognosis.The features of clinical pathology and immunohistology may help to make a correct diagnosis.

Objective To detect the expression of microRNA(miRNAs)in the late stage terminal hindgut de-velopment in fetal rats.Methods Twenty -four female rats were randomly divided into 2 groups.They were matched in proportion of male and female 21 .The experimental rats(n =1 2)received 1 0 g/L ethylenethiourea (1 25 mg/kg)by gavage on gestational day 1 1 ,and the control rats (n =1 2)received same amount of distilled water.The fetal rats were obtained by caesarean section on the gestational day 1 6 in each group.One centimeter rectum was taken out from 2 similar weight fetal rats for extracting total RNA by Trizol method.There were 24 fetal rats in each group.Chip hybri-dization was conducted after Poly(A)and biotin added to the RNA.Then,the chip was washed and dyed,and scanned thereafter.According to the differences in the expression profile of miRNAs and target gene analysis results,the miRNAs probably regulating the key gene of hindgut development was selected for target genes expression analysis.Results Compared with control group,expressions of 1 1 1 miRNAs in terminal hindgut of experimental group were up -regulated on the gestational day 1 6,and 1 1 7 miRNAs were down -regulated.Ten miRNAs of biggest differential expression be-tween them were selected for target genes prediction,pathway analysis,and Gene Ontology analysis.The results showed that some genes were closely related to rat fetus terminal hindgut growth and development,such as Shh,Hoxd13,and so on.According to the differential expression of miRNAs and target genes analysis,miR -1 93 might have an important role in the Hoxd13 gene for anorectal development.Real -Time PCR and Western blot showed that the expression of Hoxd13 and its protein level were significantly decreased when miR -1 93 highly expressed in rat intestinal epithelial cells,and the difference was statistically significant compared with the control group(1 .00 ±0.1 2 vs 0.71 ±0.1 0) (0.88 ±0.06 vs 0.75 ±0.08)(t =3.329,3.1 30;P =0.029,0.01 1 ).Conclusions miRNAs probably have an im-portant regulatory role in their target gene expression in terminal hindgut development of fetal rats,and miR -1 93 can significantly inhibit the expression of Hoxd13 gene in rat intestinal epithelial cells.
