Objective To analyze the effect of intravenous dripping of 3% sodium chloride solution on prevention of diluted hyponatremia during transurethral vaporization of the prostate (TUVP). Methods Eighty-five cases with benign prostatic hyperplasia (BPH) accompanied with typical lower urinary tract symptoms (LUTS) were divided into two groups during undergoing TUVP operation: the control group(n=38) given Ringer's solution dripping (3ml/min) and the concentrated sodium chloride injection group(n= 47) given 3% sodium chloride solution dripping (2～4ml/min). All of the operations were taken via Wolf electric resection system, and the operation time was≥60 min. The complete blood count and serum electrolyte were determined before operation and 60 minutes after operation beginning, and the data were compared between the two groups. Results The decrease amplitude of serum sodium was obviously smaller in concentrated sodium chloride injection group[(1.45±5.14)mmol/L] than that in the control group[(7.79±6.64) mmol/L] 60 minutes after operation beginning (P<0.05). Conclusions Giving 3% sodium chloride solution by intravenous drip during TUVP may reduce the severity of diluted hyponatremia and postpone the occurrence of hyponatremia, and thereby decrease the risk of transurethral resection syndrome.

Objective To prepare a new type of micropore porcine acellular dermis matrix with the aid of laser (LPADM),and to validate the healing effect of the LPADM through the phrase Ⅰ composite transplanting on the back of the full- thickness skin defects in SD rats.Methods In vitro,the allogeneic fibroblasts were separately cultured with the LPADM (LPADM group) or the non-pore PADM (non-pore LPADM group),while fibroblasts cultured by pure medium were used as control.After culture of 1 day,3 days and 5 days,the contents of IL-10,IL-6,TGF-β1,LN,VEGF expressed by fibroblasts were determined by double-antibody sandwich ELISA method.In vivo,the phrase Ⅰ transplantations of LPADM graft with split-thickness autologous skin were carried on the backs of the full-thickness cutaneous defects of SD rats.The healing condition was observed and analyzed by histological tests.Results The differences of the absorbance value between the LPADMgroup,PADM group and control group in each day were not statistically significant (F=0.050-1.763,P＞0.05).The transplantation of LPADM graft with split-thickness autologous skin graft resulted in high rate of surviving without signs of rejection 3 weeks later.After 1-month of transplantation,the regenerated skin was well enough to be lifted without any serious scars.Conclusions The phrase Ⅰ transplantation of LPADM graft with split-thickness autologous skin graft can accelerate the healing process of full-thickness skin wounds with high biological safety.

Objective To evaluate the procedure of diagnosis and treatment for cystitis glandularis in female. Methods Forty-seven patients were classified into 3 groups randomly after being operated by tuansurethral resection:15 cases without any other therapy(A group), 16 cases with bladder instillation of pirarubicin afterward (B group), 16 cases with bladder instillation of mitomycin afterward (C group). Symptomatic reliof and recurrence were investigated in 1-year follow-up visit. Results Forty-four cases had fulfilled the entire follow-up visit. The effective rates of the three groups were 38.5%,87.5% and 86.7% respectively (X2=13.80,P＜0.01 ), the recurrence rate was 30.8% ,0,13.3% respectively (X2=4.86,P＞0.05).Conclusions The clinical situation of cystitis glandularis has no specificity. Cystisis glandularis has diversification of the clinical symptoms, urodynamics. Transurethral resection with bladder instillation is more effective than transttrethral resection simply, the recurrence rate is lower.

AIM: To investigate the inhibitory effects of genistein(Gen) on mouse allergic contact dermatitis(ACD).METHODS: The animal model of ACD was induced by DNFB.The effects of different doses of Gen on mouse ear swelling,body weight,histopathological changes in mouse ear skin,thymus index and spleen index were observed.RESULTS: All groups of Gen inhibited mouse ear swelling induced by DNFB significantly.The infiltration of inflammatory cells and thymus index were also reduced.However,the increase in mouse body weight was not affected.Low dose of Gen increased spleen index,high dose of Gen decreased spleen index.CONCLUSION: Genistein has significant inhibitory effects on mouse ACD induced by DNFB.

Objective To study the effect of early mechanical ventilation in treatment of patients with severe acute pancreatitis(SAP).Methods Fifty-two patients with SAP admitted in the First People's Hospital of Zhaoqing from January 2010 to January 2015 were randomly allocated into two groups (n =26),early mechanical ventilation group(observation group) and conventional mechanical ventilation group(control group).Patients in the observation group treated with early lung protective ventilation when PaO2 ＜ 13.3kPa.Patients in the control group treated without mechanical ventilation untill PaO2 ＜ 8kPa.The symptoms,the extent of inflammatory reaction,the severity of lung lesions and the mortality of two groups were compared through monitoring vital signs,abdominal circumference,APACHE Ⅱ score,bladder pressure,oxygenation index (PaO2/FiO2),C reactive protein (CRP),procalcitonin (PCT),hospital stay and mortality.Results No statistically significant differences in the APACHE Ⅱ score,bladder pressure,oxygenation index,CRP and PCT in two groups before treatment were observed(P ＞ 0.05).The APACHE Ⅱ score (12.8 ± 7.6) points,bladder pressure (14.9± 7.9) cmH2O,CRP (48.8 ± 30.1) rmg/L,PCT (1.25 ± 0.55) μg/L,mortality (3.84％) of the observation group after treatment were significantly lower than those of the control group (t =2.057,2.091,3.252,2.697,x2 =4.305,all P ＜ 0.05),while the oxygenation index in the observation group [(300.0 ± 34.9) mmHg] was significantly higher than that in the control group [(278.1 ± 32.8) mmHg],the difference of the two groups was statistically significant (t =3.322,P ＜ 0.05).Conclusion Early lung protective ventilation is safe and effective for treatment of the patients with SAP.

AIM: To explore the effects of CD40-CD40 ligand (CD40L) interaction on endothelial cells (ECs) procoagulant activity. METHODS: A co-incubation system of macrophage membrane with ECs was established. The changes in ECs procoagulant activity and tissue factor (TF) expression were studied by anti-CD40L antibody blocking analysis. RESULTS: Coincubation with macrophage membrane (cell ratio 1∶1) for 6 hours resulted in a 10.9-fold increase ( P
