ABSTRACT

Obesity-related hypertension is a common hypertension as well as a common chronic disease with wide distribution and great harm to human health. In recent years, this disease has become one of the hot issues of public health due to the significant increase in prevalence. The pathogenesis and pathway of obesity-related hypertension are not yet clear, and the research on its pathogenesis has received extensive attention. Studies have shown that they are regulated in most biological processes, including differentiation, proliferation, migration, and apoptosis. The miR-200 family is a group of miRNAs, which have been suggested to play a crucial role in obesity-related hypertension and glucolipid metabolism dysfunction in recent years. This paper reviews relevant research results, suggesting that the expression level of miR-200 family in obese patients with hypertension is higher than that in healthy people, which regulates the occurrence and development of hypertension through mediating oxidative stress response and GATA expression level. This review reveals the relationship between miR-200 family and obesity-related hypertension, which offers new clues to explore potential therapeutic targets for obesity-related hypertension.

ABSTRACT

Objective To investigate the clinical efficacy of laparoscopic versus open omental patch repair for perforated peptic ulcer. Methods One hundred and twenty-seven patients who underwent omental patch repair for perforated peptic ulcer were analyzed retrospectively. There were 74 cases in the laparoscopic repair group (LR group) and 53 cases in the open repair group (OR group) respectively. Operative time, intraoperative blood loss,postoperative pain at 1 d and 3 d.time to first flatus and resumption of diet, time to drainage removal,surgical site infections (wound infection and intra-abdominal abscess),systemic complications and length of postoperative hospital stay were compared. Results LR group experienced less intraoperative blood loss[(32.7 ±25.6) ml], lower postoperative pain at 3 d[(2.8 ±1.5) scores], earlier time to first flatus [ (25.8 ± 20.1) h] and resumption of diet [ (2.7 ±2.1) d ], shorter time to drainage removal [(2.0±1.5) d], less wound infection (0) and shorter hospital stay[(4.8 ±2.3) d] than those in OR group [(53.2±30.0) ml, (36.9±27.9) h, (3.7±2.0) scores, (3.6±2.3) d,(2.9±2.2) d,9.4%(5/53), (6.6±4.0) d](P< 0.01 or <0.05). There were no significant differences in operative time,postoperative pain at 1 d, incidence of intra-abdominal abscess and systemic complications between the two groups. There were no suture-site leakage, reoperation and death in two groups. Conclusions Laparoscopic omental patch repair for perforated peptic ulcer is safe and efficacious. It has significant advantages over open approach with respects of less postoperative pain,earlier return of bowel function,less wound infection and shorter hospital stay.

ABSTRACT

Objective To explore the effects and mechanism of hydrogen sulfide on myocardial ischemia reperfusion in rats. Methods With sodium hydrogen sulfide (NaHS) as a donor of hydrogen sulfide ( H2S), we established myocardial ischemia-reperfusion injury model in rats. The SD rats were randomly divided into control group,myocardial ischemia reperfusion group (I/R group), H2S group,and H2S and glibenclamide (H2S + GLI)group. We monitored the hemodynamics index of rats, including heart rate, arterial pressure, left ventricular pressure. The rate of ventrical arrhythmia was also observed in each group. Results H2 S significantly reduced the ventricular arrhythmia (VA) occurrence (H2S group 66.5% vs I/R group 33.5% (P <0.05) and score in myocardial ischemia reperfusion rats (H2S group 2. 6 ±0. 7 vs I/R group 4. 5 ±0. 8(P<0.05). The KATP channel blocker,glibenclamide,could weaken the antiarrhythmic effects of H2S ( H2S group 2. 6 ±0. 7 vs. H2S + GLI group 4. 0 ± 0. 6, P < 0.05 ). Conclusions H2S has the protective effect against myocardial ischemia reperfusion damage. This function may be associated with the KATP signal transduction pathway in cells.

ABSTRACT

Objective To investigate whether nobiletin could enhance chemotherapeutic drug-induced cell proliferation inhibition and apoptosis in breast carcinoma cells MDA-MB-231 in vitro.Methods MDA-MB-231 cells were exposed to nobiletin and different chemotherapeutic drugs at different concentration.The cell proliferation inhibitory rate was observed by MTT,apoptosis was detected by DNA Ladder,flow cytometry (FCM),and ELISA,and an NF-?B electrophoretic mobility shift was conducted by EMSA and ELISA.Results The combination of nobiletin (20 ?mol) with Taxol (1 nmol) or Doxorubicin (50 ng/mL) resulted in a significant inhibitory rate of cell growth and more apoptosis in MDA-MB-231 cells of 75.1% and 82.6% compared with either of them alone (40% and 45%),respectively.DNA Ladder and FCM assay showed that nobiletin could promote the cell apoptosis induced by chemotherapeutic drug.EMSA and ELISA assay showed that nobiletin could inhibit NF-?B activity in nuclear and cytoplasm of MDA-MB-231 cells.Conclusion The current results suggest that nobiletin could enhance the inhibition of chemotherapeutic drug on cell proliferation and cell apoptosis of breast carcinoma cells MDA-MB-231,the mechanism may be related to down-regulate the NF-?B activity in vitro.
