Objective To investigate the protective effect of pinacidil on the intestinal mucosa of scalded rats and the mechanism. Methods A total of 24 healthy SD rats were randomly divided into normal control group, burn group, and pinacidil treated group. Rats in burn group and pinacidil treated group were inflicted with 30% TBSA Ⅲ degree burn and resuscitated intraperitoneally with Ringer's solution immediately after burn. Pinacidil was injected intraperitoneally into rats in pinacidil treated group at the dose of 2 mg/kg. Mitochondrial respiratory function intestinal mucosa and levels of reactive oxygen species (ROS), maleic dialdehyde (MDA), and superoxide dismutase (SOD) in plasma were determined at 6 h after burn. Results Mitochondrial respiratory function control rate (RCR), ST3, and SOD levels in pinacidil treated group were evidently higher than those in the burn group. However, ST4, MDA, and ROS levels in pinacidil treated group were significantly lower than those in the burn group, but ST4 was not significantly different from that in the normal control. Conclusion Pinacidil can attenuate the damage of intestinal mucosa in scalded rats.

BACKGROUND: Obesity is serious complex disease determined by multiple genetic factors. Body mass index (BMI) is a common phenotype for obesity. Although some candidate genes have been shown to be related with BMI variation, the underlying substantial relationship remains poorly understood.OBJECTIVE: To investigate whether estrogen receptor-α (ER-α) Pvull genetic polymorphism is associated with BMI variation.METHODS: In total 390 premenopausal women from a local population of Nanchang City in Jiangxi Province People's Hospital.Body weight and height were measured. All participants were genotyped at the ER-α Pvull locus using polymerase chain reaction-restriction fragment length polymorphism.RESULTS AND CONCLUSION: The ER-α Pvull genotype frequencies of PP, Pp and pp were 0.133, 0.485 and 0.382,respectively. The distribution of ER-Pvull genotypes was in accordance with Hardy-Weinberg equilibrium (HWE) (P ＞ 0.05).There was no significant correlation between ER-α Pvull genetic polymorphism and BMI variation (P = 0.338). These findings indicate that ER-α Pvull genetic polymorphism does not greatly affect BMI variation of premenopausal women in Nanchang region.

Background Rosuvastatin has been unanimously recognized as an very highly efficacious statin. Rosuvastatin significantly reduced microalbuminuria and its powerful anti-inflammatory effect confer anti-atherosclerosis in patients with essential hypertension. Objective To study the influence of rosuvastatin on microalbuminuria and arteriosclerosis plaque of carotid and coronary arteries in hypertensive patients. Methods Seventy-six hypertensive patients were randomly to receive conventional anti-hypertensive drugs (amlodipine 5 mg/d and telmisartan 80 mg/d,n=37) or rosuvastatin (10 mg QN) on the top of conventional anti-hypertensive drugs (n=39). The blood pressure,levels of microalbuminuria,echocardiography and helical computerized tomography were examined before and 8 months after treatment in all patients. Results After 8 months of treatment,SBP and DBP were decreased in both group [conventional treatment from (166.3?11.2)/(92.4?8.2) to (133.6?9.8)/(85.5?6.1)mmHg,combined group from (165.6?10.5)/(91.5?6.7) to (128.1?9.2)/(81.1?5.9)mmHg]. Combined treatment significantly reduced the levels of microalbuminuria [(31.6?21.8) to (23.2?19.8)mg/g,P

Objective To investigate the expression of interleukin-6(IL-6),high mobility group protein B1 (HMGB1)and Survivin in patients with gastrointestinal stromal tumors (GISTs)and the relationship between them.Methods 43 patients with GISTs and 30 healthy controls from Jan.2009 to Dec.2012 in Nanchong Central Hospital was enrolled.Expressions of IL-6,HMGB1 and Survivin in serum were assessed with enzyme linked immunosorbent assay(ELISA) and the correlation among IL-6,HMGB1 and Survivin was analyzed.Results The serum levels of IL-6,HMGB1 and Survivin in patients with GISTs((0.61 ±0.05)ng/ml,(3.54 ±0.74) ng/ml,(0.15 ± 0.04)ng/ml,respectively)were higher those that in the healthy controls((0.32 ± 0.03)ng/ml,(1.81 ± 0.06)ng/ml,(0.07 ±0.02)ng/ml,respectively).Among the 43 GISTs,the expressions of IL-6,HMGB1 and Survivin in benign,potentially malignant and malignant group increased gradually.The expressions of IL-6 in each group were (0.55 ± 0.02) ng/ml,(0.59 ± 0.02) ng/ml,(0.64 ± 0.03) ng/ml,respectively,The expressions of HMGB1 in each group were (2.82 ± 0.55) ng/ml,(3.46 ± 0.16) ng/ml,(4.00 ± 0.61) ng/ml,respectively.The expressions of Survivin in each group were (0.10 ± 0.01) ng/ml,(0.15 ± 0.02) ng/ml,(0.18 ± 0.03) ng/ml,respectively.Expressions of IL-6 and HMGB1,IL-6 and Survivin,and HMGB1 and Survivin were positively correlated(r =0.699,P ＜0.05;r =0.774,P ＜0.05;r =0.595,P ＜0.05,respectively).Conclusion The high expression of IL-6,HMGB1 and Survivin may together contribute to the malignancy,invasion and metastasis of GIST.Detection of these three markers may be useful in judging the malignancy degree and predicting the prognosis of GIST.

Objective To investigate the effects of tumor-necrosis factor α (TNF-α) on the expressions of proprotein convertases (PC) and its relationship with the inhibition of hepatitis B virus (HBV) replication.Methods HepG2.2.15 cells cultured routinely were exposed to 20 μg/L recombinant TNF-α and/or 20 μmol/L PC inhibitor (DEC) for 18 h.Then Followed cells werecollected and cell total RNA and HBV DNA were extracted.PC mRNA and core-associated HBV DNA were measured using real-time polymerase chain reaction (PCR) techniques.Measurement data was compared using t-test.Results When PC mRNA expressions in the blank group was as to 1,the expressions of PC1/3、PC2、furin、PC4 、PC5/6 、PACE4 and PC7/8 mRNA in HepG2.2.15 cells treated with 20μg/L TNF-α treatment for 18 h were all up-regulated,which were 3.3±0.7、79.3±3.3、77.5±1.3、19.2±3.1、1.3±0.1、1.4± 0.2、274.8± 7.1,respectively (all P＜0.05).Treatment of 20 μg/L recombinant TNF-α for 18 h significantly reduced core-associated HBV DNA compared with blank gourp (0.21∶1,t =8.79,P =0.002),while 20 μmol/L DEC significantly up-regulated core-associated HBV DNA (3.84∶ 1,t=7.67,P=0.004).Moreover,core-associated HBV DNA in group of DEC and TNF-α treatment was significantly higher than group of TNF-α treatment (0.31∶0.21,t=10.49,P=0.007).Conclusion Up-regulated PC mRNA expression induced by TNF-α is significantly associated with the inhibition of HBV replication.

Objective When bacterial cellulose (BC) is used as a scaffold material in tissue engineering,the nano-structure of BC may not provide enough space for animal cell growth and differentiation which would not achieve a perfect application in tissue engineering.In order to solve this problem,a novel green approach is developed in this research to produce bacterial nanocellulose materials with micropores ranging 50-800 μm.Methods Several ratios of hydrogen peroxide to sodium chlorite were used to react instantly to produce a large number of bubbles in BC hydrogels,which formed micropores with diameters ranging 50-800 μm.Optical microscopy and scanning electron microscope were used to evaluate microporous BC hydrogels and verify the existence of micropores.Results The size of pores could be regulated along with the changes in the amount of reactants used in the experiment.Fourier transform infrared spectroscopy verified that no cellulose was oxidized.Water content of the microporous BC hydrogels was similar to that of the original BC hydrogels.The Young's modulus of microporous BC hydrogels was 26.1 kPa,which was lower than that of the original BC hydrogels (69.9 kPa).Thiazoyl blue tetrazolium bromide (MTT) test displayed a higher viability on the microporous BC hydrogels compared to the growth on the unmodified BC substrates.Conclusions This study provides a convenient and promising way to prepare microporous materials,which may not be limited to only BC material,but could be used in other hydrogels.The proposed approach is suitable for extensive industrialization.
