Objective To discuss the clinical effect of transurethral cystitis glandularis electrocision combined with treating the diseases under bladder outlet in female.Methods One hundred and two female cases of cystitis glandularis who received transurethral electrical resection of the bladder mucosa combined with treating the diseases under bladder outlet were selected as experimental group,and another 78 female cases were selected as control group,who only received transurethral electrical resection of the bladder mucosa.The visual analogue score (VAS) was observed before and after a 12-week treatment,and the efficacy was evaluated by analysis of non parameter RIDIT.Results The operation time in experimental group and control group were 15-40 (26 ± 13) min and 8-19 (13 ± 5) min,respectively,and there was significant difference between two groups (P ＜ 0.05).Two groups cases urinated smoothly after the removal of catheter,without the occurrences of urinary fistula and incontinence.During the 12-weeks of follow-up,44 cases were cured,31 cases improved,15 cases were effective and 12 cases unimproved in experimental group; 26 cases were cured,21 cases improved,16 cases were effective and 15 cases unimproved in control group.There was significant difference between two groups (R =0.576,95％ CI0.519-0.633,P＜ 0.05).Conclusion Although the operation time is lengthened by transurethral cystitis glandularis electrocision combined with treating the diseases under bladder outlet in female,this method obviously improves curative effect.

Objective To investigate the effects of hydrogen gas on the myocardial injury in rats with endotoxemia.Methods Forty-eight healthy male Sprague-Dawley rats,weighing 200-220 g,were randomly divided into 4 groups (n =12 each ):control group (group C ),hydrogen gas control group (group HC ),endotoxemia group (group E) and hydrogen gas + endotoxemia group (group LH).Endotoxemia was induced by intraperitoneal lipopolysaccharide (LPS) 20 mg/kg in groups E and LH,while the equal volume of normal saline was given in groups C and HC.After LPS administration,the rats were exposed to the air containing 2％ hydrogen gas for 6 h in groups HC and LH,and the rats were exposed to the air for 6 h in groups C and E.Blood samples were taken from the abdominal aorta after 6 h inhalation of hydrogen gas to determine the serum level of cTnI.The hearts were then removed to determine the content of TNF-α and IL-6 and expression of phosphorylated nuclear factor κB ( NF-κB) inhibitory protein (p-IκB-α) and p38 mitogen-activated protein kinase (p-p38MAPK) in the myocardial tissues.Results Compared with group C,no significant change was found in the levels of cTnI,TNF-α and IL-6 and expression of p-IκB-α and p-p38MAPK in group HC ( P ＞ 0.05),and the levels of cTnI,TNF-α and IL-6 were significantly increased and the expression of p-IκB-α and p-p38MAPK was up-regulated in groups E and LH ( P ＜ 0.05).Compared with group E,the levels of cTnI,TNF-α and IL-6 were significantly decreased and the expression of p-IκB-α and p-p38MAPK was down-regulated in group LH ( P ＜ 0.05).Conclusion Hydrogen gas can reduce the myocardial injury in rats with endotoxemia,and inhibition of the p38MAPK and NF-κB pro-inflammatory pathway and reduction of the inflammatory response of myocardial tissues are involved in the mechanism.

Objective To study the effect of fasudil on inhibiting the Rho/ROCK signaling pathway under high glucose in human mesangial cells (HMCs) inflammation and fibrosis. Methods Synchronized HMCs were divided into following groups: (1) Normal glucose control group ( NG, 5. 5 mmol/L glucose) ;(2) High glucose group (HG, 30 mmol/L glucose) ; (3) Mannitol group (Man, 5.5 mmol/L glucose + 24. 5 mmol/L mannitol) ; (4) High glucose + fasudil group ( HG + F, the concentrations of fasudil were 25 ,50 and 100 μmol/L, respectively). Collect the supernatant and cells at 0, 12, 24, 36, 48 and 72 h respectively, and determine the concentration changes of the RhoA, ROCK- Ⅰ, connective tissue growth factor (CTGF)mRNA with real-time PCR method in the cells, then used the ELISA method to check the protein content of the fibronectin ( FN) , CTGF, TNFα in the supernatant. Results ( 1) RhoA, ROCK- Ⅰand CTGF mRNA of the HMCs cultured under the high glucose expressed significantly higher than those in the normal group, and there was certain time-dependence. Besides, there was no statistic significance by comparing Man and NG. (2) Under the high glucose situation, after the fasudil pretreatment with different concentrations and 24 h or 48 h culture with high glucose, RhoA, ROCK- Ⅰ , CTGF mRNA expression was significantly decreased in HG + F, compared with HG, and there was certain concentration-dependence. (3) High glucose increased the FN, CTGF, TNFα protein secretion of HMCs in a time-dependent manner, but normal glucose and mannitol had no such effect. (4) After the fasudil pretreatment with different concentrations and culture with high glucose for 12, 24, 36, 48, 72 h, the FN, CTGF, TNFα protein secretion was significantly reduced compared with HG. Conclusion Fasudil can reduce the secretion of downstream inflammatory factors and cytokines by inhibiting high glucose-activated HMCs Rho/ROCK signaling pathway, and reduce the inflammation and fibrosis of HMCs. This provides a new basis for the therapeutic target in the treatment of diabetic nephropathy.
