Objective Non-alcoholic steatohepatitis(NASH) can progress to liver fibrosis and cirrhosis. Now there are few effective drugs to treat NASH. The aims of this study was to investigate the efficacy of anetholtrithione in the prevention and treatment of NASH in rats induced by high-fat diet. To evaluate the weight,liver index, serum aminotransferase activity and histological features. Methods Sixty SD male rats were divided into six groups. The controlled group(n=10) were fed with normal diet; the NASH model group(n=10)were fed with high-fat diet; the anetholtrithione prevention groups were fed with high-fat diet, and anetholtrithione.The rest rats were fed with high-fat diet, and twelve weeks later they were divided into three groups further. They were anetholtrithione treatment group, diet group and anetholtrithione +diet group. The anetholtrithione treatment group was fed with high-fat diet and anetholtrithione, diet group was fed with normal diet, and anetholtrithione+diet group was fed with normal diet and anetholtrithione. Sixteen weeks later, all rats were sacrificed. Results The anetholtrithione treatment group, diet group and anetholtrithione +diet group had a beneficial effect on lowing weight, liver index, serum aminotransferase activity. A significant improvement in some histological features such as steatosis and inflammation were also observed. Conclusion Anetholtrithione and diet therapy are effective in ameliorating NASH in rats.

Objective To explore the role of long noncoding RNA ( lncRNA) CTD-2012K14. 6 in the development of gestational diabetes mellitus (GDM) related macrosomia. Methods The quantitative real-time PCR ( qRT-PCR) was performed to measure the expression of CTD-2012K14.6 in placentas of women with or without GDM, and the quantity of CTD-2012K14. 6 expression and its association with fetal weights were analyzed; Bioinformatic analysis was performed to predict the downstream molecules. CTD-2012K14. 6 over-expressing lentiviral and siRNA was constructed in human trophoblastic cell line HTR-8/SVneo cells, qRT-PCR and Western blot (WB) were used to invest its effect in modulating the expression of downstream molecules. Results The expression of CTD-2012K14.6 in GDM placentas was significantly higher than that in normal controls (1.70 ± 0.63 vs 1.00 ± 0.56,t=3.68,P＜0.01), and positively correlated with fetal weight (r=0.8501, P＜0.01); on-line analysis showed that CTD-2012K14.6 was located at chr16:67,549,214-67,563,958, which was located in the intron of CCCTC-binding factor( CTCF); Up-regulating CTD-2012K14.6 could significantly reduce the expression of CTCF mRNA and protein, and increase the expression of insulin-like growth factor-Ⅱ( IGF-Ⅱ) mRNA and protein, while down-regulating CTD-2012K14.6 could significantly increase the expression of CTCF mRNA and protein, and reduce the expression of IGF-ⅡmRNA and protein. Conclusion The CTD-2012K14. 6 may play an important role in the pathogenesis of GDM related macrosomia by upregulating the expression of CTCF and IGF-Ⅱ.

This study was aimed to distinguish Leonurus japonicus samples produced from different regions and growth environments in Sichuan by electronic nose. The sensor response value of odors of Leonurus japonicus sam-ples were obtained through electronic nose. Principal component analysis (PCA) and discriminant factor analysis (DFA) were used to combine the optimum feature parameters. The results showed that the PCA distinguish index was 82, and the DFA comprehensive classification rate was 97.96% among samples from different regions. The PCA distin-guish index was 84, and the DFA comprehensive classification rate was 100% among samples from different growth environments. The distinguishment and differentiation were effective. It was concluded that electronic nose can be ap-plied to identify the origin and growth environment of Leonurus japonicus from Sichuan to provided reference for odor differentiation.

Objective To investigate the incidence and risk factors of acute kidney injury(AKI)after different types of cardiac valve replacement surgery. Methods A single cohort of 1113 patients who received cardiac valve replacement surgery from April 2009 to March 2010 in Zhongshan Hospital,Fudan University were prospectively analyzed.Multivariate Logistic regression analysis was used to evaluate possible risk factors associated with post-operative AKI.Akl was defined as a relative 50% increase or an absolute increment of 26.4 μmol/L in Scr within 48 hours and/or urine volume <0.5ml·kg-1·h-1 up to 6h.Results Of the 1113 patients, the incidence of AKI was 33.24%.In-hospital mortality of AKI patients was 6.49%,which was 5.373 times higher than that of non-AKI patients(P<0.01).The incidence of AKI in patients who simultaneously received cardiac valve replacement and coronary artery bypass grafting was 75.00%,which was significantly higher as compared to other types of valve replacement surgery(P<0.01).Unconditional multivariate Logistic regression analysis revealed that male,old age,long extracorpeal circulation (CPB)time(≥120 min)and combined with coronary artery bypass grafting surgery were the independent predictors of AKI episodes,and the corresponding OR values were 1.455,2.110,1.768 and 2.994 respectively. Conclusions AKI is a common and serious complication after cardiac valve replacement surgery.Patients who received combined cardiac surgery as valve replacement and coronary artery bypass grafting have higher incidence of AKI.Old age,male,long CPB time(≥120 min)and combined with coronary artery bypass grafting surgery are the independent risk factors of post-operative AKI for patients undergoing cardiac valve replacement surgery.

Objective To evaluate the effects of probioties on inflammation,intestinal flora and mucosal tumor necrosis factor alpha(TNF-?)expression in experimental colitis rats.Methods Thirty Wistar rats were randomly divided into normal control group(NC),model control group(UC),and pro- biotics treatment group(PC).The experimental colitis were induced by trinitrobenzene sulfonie acid (TNBS)/ethanol enema.Rats in PC group were fed with Bifico[live probiotics of combined bifidobacte- rium(Bif),lactobacillus (Lac) and enterococcus]by 2.2?10~9 colony-forming unit (CFU)/d for 4 weeks.Inflammatory scores and mucosal morphological changes under light microscopy were studied. Plasma endotoxin levels,expressions of TNF-?and interleukin-6 (IL-6) in mueosa were measured. Enteric microorganisms in cecum were fostered with standard methods.Results Inflammatory scores in PC group decreased compared with those in UC group(7.94?0.85 vs 10.25?1.36,P＜0.05),but still higher than those in NC group(7.94?0.85 vs 4.35?0.88,P＜0.01).There was a significant alteration in the enteric microbial flora,Bif and Lac were decreased significantly in UC group,Bifico supplement ameliorated this imbalance.Plasma endotoxin and mucosal TNF-?levels in PC were lower than those in UC group[endotoxin:(93.33?21.22)pg/ml vs (121.25?39.07)pg/ml;TNF-?:67.51?14.63 vs 85.99?18.17,P＜0.05],but higher than those in NC group[endotoxin:(93.33?21.22) pg/ml vs(35.20?15.12)pg/ml;TNF+?:67.51?14.63 vs 43.28 4?19.98,P＜0.01].There was no statistically significant difference in mucosal IL-6 levels between PC group and UC group,though its level in PC group was lower than that in UC group(155.22?34.01 vs 184.09?29.11,P＞0.05),but higher than that in NC group(155.22?34.01 vs 108.73?37.35,P＜0.01).Conclusions Probiotics can attenuate inflammation of experimental colitis of rats through reinstituting gut flora bal- anee.Improving gut flora imbalance,reducing endotoxin and pro-inflammatory cytokines may be the effects of probiotics.

Objective To study the clinical value of transcervical resection under hysteroscope in treatment of placental remnants.Methods From March 2003 to April 2006,14 cases of placental remnants were treated with transcervical resection under hysteroscope.They included 3 cases of term birth,and 11 cases of midtrimester induction of labor.Drug pretreatment was performed for those who had more than 80 U/L of blood beta-human chorionic gonadotropin (?-hCG) level,including mifepristone (RU486), Chinese herbs and methotrexate(MTX).RU486 was taken orally at 25 mg,three times daily and misoprostol was given 600 ?g at one dose on the third day.MTX was given by deep intramuscular injection at 1 mg/m~2 if ?-hCG was higher than 150 U/L.Bipolar evaporation was used in the operation with alternation of resection and forceps holder under ultrasonographic supervision.After operation a circular contraceptive device was placed followed by hormone periodic treatment such as estradiol valerate for 2-4 months.Results Under the monitoring by ultrasonography,14 operations were all performed smoothly.The follow-up was from 6 months to 2 years.Menstruations in almost all the cases were recovered,and 3 cases of those were pregnant and delivered smoothly 4,6 and 7 months after operation.Conclusion The transcervical resection under hysteroscope is useful in treatment of placental remnants with obvious effects,little trauma and few complications.
