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.

OBJECTIVE:To provide reference for health service support at high altitude area. METHODS:375 servicemen who rapidly entered high altitude area were investigated by questionnaire in 2013 to investigate the compliance of using high alti-tude special medicines and incidence of mountain sickness and analyze its correlation. RESULTS:375 questionnaires were distribut-ed and 324 questionnaires were collected with effective response rate of 86.4%. The utilization rate of Multivitamin tablet,Skin cream and Lip balm for high altitude area were 30.9%,13.3% and 40.1% respectively. The compliance of using high altitude spe-cial medicines had effect on the incidence of related mountain sickness. The incidence of mountain sickness of people who followed the physician’s instructions was significantly lower than those who did not. The difference was statistically significant(P<0.05). CONCLUSIONS:High altitude special medicines can relieve and prevent the mountain sickness. But the overall compliance of us-ing high altitude special medicines was not ideal. The education of high altitude special medicines should be strengthened,and dos-age forms and medicine instruction should be enhanced to improve its compliance and play better protective effect.

Objective To investigate the relationship between serum cystain C,urinary neutrophil gelatinase?associated lipocalin(NGAL),uri?nary kidney injury molecule?1(KIM?1)and preeclampsia,and explore the value in predicting preeclampsia and early kidney damage. Methods A total of 30 cases of pregnant women with severe preeclampsia,30 cases of mild preeclampsia and 60 cases of healthy pregnant women admitted in the Second Hospital of Jilin University from October 2014 to July 2015 were enrolled for the study. ELISA was performed to check urinary KIM?1 and urinary NGAL,and the serum cystatin C was detected by immune turbidity method. Results KIM?1,NGAL,serum cystatin C in the preeclampsia were significantly higher than the normal control group(P<0.05). In addition,with the development of their concentrations,the progression of pre?eclampsia gradually rise;BMI,e?GFR,urine protein/creatinine ratio,KIM?1,serum scystatin C and NGAL are the risk factors for preeclampsia;uKIM?1,serum scystatin C and NGAL and combined predictors of preeclampsia are taken as the early indicators of renal injury,which sensitivity are separately 83.3%,75%,88.9%,96.8%;specificity are respectively 72.7%,70%,75.6%,86.4%. Conclusion KIM?1,serum scystatin C and NGAL may reflect the progression of renal injury in preeclampsia .Combined predictors have a higher predictive value in the early renal injury of the preeclampsia.

AlM:To investigate the effects of pirfenidone ( PFD) on the proliferation and transfomring growth factor-β1 ( TGF-β1 ) expression in vitro culture rat corneal stromal cells.METHODS: Corneal stromal cells from 8 to 10wk SD rats were isolated, cultured and treated with different concentrations of PFD 0mg/mL (control group), 0. 15mg/mL (experimental group▏), 0. 3mg/mL (experimental group‖), 1mg/mL (experimental group Ⅲ) for 48h. CCK-8 assay was performed to assess cell proliferation, while immunocytochemistry and Western Blot were used to detect the expression of ki-67 and TGF-β1 expression, respectively. RESULTS: Compared with control group, PFD significantly inhibited the proliferation in a dose -dependent manner ( all P < 0. 05 ), so was protein expression of ki-67. PFD significantly down-regulated the expression of TGF-β1 in a dose-dependent manner (P<0. 05).CONCLUSlON: Pirfenidone can significantly inhibit the proliferation of rat corneal stromal cell by down regulating TGF-β1 expression, therefore, it has potential prospect in lightening the corneal wound healing reaction.
