Objective To analyze the correlative factors of peptic ulcer recurrence in the elderly. Methods From January to December 2009,169 elderly patients (≥ 60 years old)with peptic ulcer delected by edoscopy were enrolled,whose treatment and usage of medication were analyzed.Data of treatment and recurrence in 3-year follow-up were recorded.Mann-Whitney rank sum test and Logistic regression analysis were performed to analyze the correlated factors.Results The potential risk factors associated with recurrence of peptic ulcer in the elderly were screened and analyzed by single factor analysis,and ulcer size, ulcer location, concomitant usage of drugs, smoking and condition of Helicobacterpylori (H .pylori )infection at the end of follow-up were found to be correlated with recurrence of peptic ulcer in the elderly.After adjusting age and gender,the potential risk factors were analyzed by a Logistic stepwise regression model.Smoking (OR = 1 .788,P = 0.001 ),combined medication (OR=6.202,P =0.015 ),ulcer size (OR =2.697,P =0.032 )and condition of H .pylori infection at the end of follow-up (OR=43.784,P =0.007)were found to be correlated with recurrence of peptic ulcer in the elderly.Conclusion Smoking,combined medication,ulcer size and condition of H .pylori infection at the end of follow-up have an impact on peptic ulcer recurrence in the elderly.

Purpose To assess the effect of pelvicfloor electrical stimulation treatment by transperineal sonography, so as to provide guidance for postpartum pelvic floor rehabilitation.Materials and Methods Thirty-one delivery women who received postpartum pelvicfloor rehabilitation were selected as research group and 30 non-pregnant young women as control group in the study. Pelvicfloor electromyography treatment was taken in research group, and transperineal sonography was undergone in quiet state and pressure state (Valsalva operation) before treatment, after the fifth treatment and after the tenth treatment respectively to measure the bladder neck to the public symphysis edge distance (Dr, Ds), bladder neck angle (θr,θs) and bladder rotation angle (θ). A comparison was made between the research group and control group.Results①Dr and Ds in research group were both lower than those in control group (P<0.05), butθr,θs andθ were all higher than those in control group (P<0.05).②Dr and Ds showed a gradual increase (P<0.05) whilstθr presented a gradual decrease before the treatment, after the fifth treatment and after the tenth treatment (P<0.05).Conclusion Natural childbirth may damage the function of pelvicfloor; electrical stimulation of pelvic therapy is effective on postpartum pelvicfloor rehabilitation; and transperineal sonography can objectively assess the effect of this therapy.

Objective To investigate the anti-tumor effect and mechanism of curcumin in pancreatic cancer (PC). Methods Smad4 and Jab1 expressions were detected by immunohistochemistry in tumor tissues and pericarcinomatous tis?sue from 35 PC cases, and the correlation of Smad4 and Jab1 were analyzed based on the percentage of positive staining in?tissues from 21 random selected PC cases. The effect of curcumin on expressions of tumor suppressors p53, Smad4 and cell cycle inhibitor p27 were examined by Western Blotting after human pancreatic cancer cell line PANC-1 were divided into PANC-1 control group (no treatments were given) and PANC-1 curcumin group (treated with cell culture medium containing 10μmol/L curcumin). The effect of curcumin on expressions of combination of β-TrCP1 and Smad4 was examined by Co-Immunoprecipitation after human embryonic kidney cell line 293T were divided into 293T control group (no treatments were given), 293T curcumin group (treated with cell culture medium containing 10μmol/L curcumin) and 293T Jab1 group (trans?fected by HA-Jab1 plasmid). Results Compared with expressions in pericarcinomatous tissues, Smad4 was down regulated while the expression of Jab1 was upregulated in PC tissues (P<0.01), and the expression of Smad4 was negatively correlated with the expression of Jab1 (n=21, r=-0.71, P=0.007). After treated with curcumin, the protein expression of p53, Smad4 and p27 was increased in PANC1 cell, and the protein expression of the combination ofβ-TrCP1 and Smad4 was decreased in 293T cell (P<0.05). After transfected by HA-Jab1 plasmid, the protein expression of the combination ofβ-TrCP1 and Smad4 was increased in 293T cell (P<0.05). Conclusion Curcumin may have suppression effect of PC through increasing the protein expression of p53, Smad4 and p27, and the mechanism of Smad4 upregulation may be related with the inhibition of Smad4 ubiquitination process, while Jab1 may be also involved in Smad4 degradation through ubiquitination.
