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.

Objective To approach the expression and significance of CD30 in Hodgkin lymphoma cells which were transfected with mtr Ⅱ gene. Methods The CD30 expression of Hodgkin lymphoma cells in those transfected with mtr Ⅱ gene was analysed by immunohistochemical technique respectively. Results The CD30 expression rate of Hodgkin lymphoma cells which were transfected with mtr Ⅱ gene was higher than that of Hodgkin lymphoma cells which weren't transfected with mtrⅡ gene (P ＜0.01). Conclusion The mtr Ⅱ gene may be related to the malignant transformation of Hodgkin lymphoma.

Xiaoqinglong Decoction comes from Shang Han Lun, which is the main treatment for wind chill and fluid retention. It is treated as a classic formula for cold-cough, which syndromes of no sweat but tight pulse, cough, cough with white phlegm, and vomiting. This article discussed the efficacy of Xiaoqinglong Decoction in tonifying yang in lung, which can help transport phlegm, and then cough can be relieved.

Objective To determine the solubility and apparent oil/ water partition coefficient of sitafloxacin in different solvents. Methods High performance liquid chromatography (HPLC) was used. The column was Dikma Diamonsil C18 (2) (4. 6 mmí250 mm,5 μm). The mobile phase was 0. 05 mol·L-1 KH2 PO4 solution (pH was adjusted with H3 PO4 to 2. 4)-acetonitrile (7030). The column temperature was set at room temperature. The flow rate was 1. 0 mL·min-1 . The detection wavelength was 295 nm and the injection volume was 10 μL. The solubility of sitafloxacin and the apparent oil/ water partition coefficient at pH 2. 0,4. 3,5. 8,6. 6,7. 4,8. 0,10. 0 and 11. 2 were determined. Results The equilibrium solubility of sitafloxacin in water was 0. 44 mg·mL-1 and the apparent oil/ water partition coefficient was 0. 23 (lgP= -0. 64) at (37±2) ℃ . Sitafloxacin has the lowest equilibrium solubility (0. 13 mg·mL-1 ) and the highest apparent oil/ water partition coefficient in pH7. 4 buffer solution system. At pH>10 and pH<5. 8,the solubility of sitafloxacin increased obviously and apparent oil/ water partition coefficient decreased. Conclusion Sitafloxacin is insoluble in water and also poorly soluble in oil,but its solubility could be improved significantly in acidic or alkaline solution.

Objective To investigate the change of the content of polysaccharides in crude and processed Fructus Corni,thus to approach the process mechanism of Fructus Corni.Methods The content of polysaccharides in the crude and processed Fructus Corni was determined by phenol-sulfuric acid method.Results After processing with wine,the content of polysaccharides of Fructus Corni decreased from 10.12 %(content of total polysaccharidesbeing 51.41 %) to 5.91 %(content of total polysaccharidesbeing 53.10 %),decreased by 41.60 %as compared with that in the crude Fructus Corni.Conclusion After processing with wine,the content of polysaccharides decreases markedly.The results provide certain evidence for approaching the process mechanism of Fructus Corni.
