Objective To investigate the effect of multiple treatments on cystospasm after transurethral resection of prostate(TURP). Methods From 2006 to 2013, 663 patients who had received TURP for BPH were civided into 6 groups:2 were treated by kieselgel or lac-toprene urethral catheter,defined as catheter observe group. 2 were treated by warmed or ordinary temperature douche,defined as temperature observe group. 2 were treated by dicaine mixed or normal douche,defined as mixed douche observe group. The incidence rates and duration of cystospasm and visual analogue scores of pain were observed and the diversities were measured by statistics within each pair groups. Results The incidence rates and duration of cystospasm and visual analogue scores of pain of groups treated by kieselgel urethral catheter,warmed douche and dicaine mixed douche were obviously lower than the groups treated by lactoprene urethral catheter,ordinary temperature douche and normal douche. The kieselgel urethral catheter and warmed douche decreasing the irritation on mucous membrane of bladder,the dicaine decreasing the sensibility of bladder nerves may be the mechanism. Conclusion The incidence rates and duration of cystospasm and visual analogue scores of pain can be obviously decreased by treatments of kieselgel urethral catheter,warmed douche and dicaine mixed douche.

Objective To investigate the effect of indwelling double-J ureteral stents before flexible ureteroscope lithotrity in terms of operation time, postoperative hospitalization time and operation effect. Methods All clinical data of flexible ureteroscope lithotrity from 2009 to 2013 were reviewed. Operation time, postoperative hospitalization time and recurrence rate of calculus of patients who received operation directly and patients who received indwelling of double-J ureteral stents 2 weeks before operation were observed and compared. Results Op-eration time, postoperative hospitalization time, and recurrence rate of calculus of patients who received indwelling of double-J ureteral stents 2 weeks before receiving operation were obviously lower than patients who received operation directly. Conclusion Operation time, postoper-ative hospitalization time and recurrence rate of calculus can be decreased by indwelling double-J ureteral stents 2 weeks before operation.

Objective: As a potential gene therapeutic method, transcription factor decoy strategy has been used to block the transcription function of multi-transcription factors. This study aims to further verify the inhibitory effect of signal transducer and activator of transcription 5 (STAT 5) decoy oligodeoxynucleotides (ODN) on tumor growth in nude mice. Methods: The xenografted tumor model was established by subcutaneously injecting leukemia K 562 cells in nude mice. Liposome-ODN complex was directly injected into tumor body once daily every 3 days. The tumor growth and tumor size were measured everyday. Nude mice were sacrificed at the end of the experiment. The tumor was removed and weighed. RT-PCR and Western blotting were performed to detect mRNA and protein expression of bcl-xL, cyclin D1, and c-myc, respectively. Results: The tumorigenicity of K 562 cells was significantly inhibited by decoy ODN. The tumor weight was markedly reduced in decoy ODN group than mutant ODN group [(0.485 ± 0.178) g vs (0.928 ± 0.223) g, P < 0.05 ]. The tumor growth inhibition rate was 47.7%. RT-PCR and Western blotting showed that the mRNA and protein expression level of bcl-xL, cyclinD1, and c-myc were down-regulated. Conclusion: Transcription factor decoy strategy effectively blocks transcription of STAT 5 target genes in xenografted tumor of nude mice.

Objective To investigate the roles of the expressions of B cell lymphoma-2 (bcl-2) and Bcl-assosiated X (bax) in the pulmonary vascular remodeling (PVR) of pulmonary arterial hypertension (PAH) secondary to left-right shunt congenital heart disease (CHD).Methods A total of 80 SPF SD rats were randomly divided into 8 groups,shunt groups (SⅠ,SⅡ,SⅢ and SⅣ) and control groups (CⅠ,CⅡ,CⅢ and CⅣ).PAH rat model was established in the shunt groups by left-to-right shutting,and the control groups received sham operation.The rats from Ⅰ,Ⅱ,Ⅲ and Ⅳ groups were sacrificed in 4,8,12 and 16 weeks after operation.Mean pulmonary arterial pressure (mPAP) was recorded.Pathologic observations were made to assess pulmonary vascular remodeling.Their lung tissues were detected by in situ hybridization histochemistry (ISHH) technique and Western blotting for bcl-2 and bax.And apoptosis of pulmonary artery smooth muscle cells (PSMCs) and endothelial cells (ECs) were also detected by TUNEL.Results After 12 weeks or 16 weeks shunt,following indexes of the shunt groups were significantly higher than the control groups (P

Objective To summarize experiences in surgical treatments of 18 patients suffered from Ebstein's anomaly with intracardiac repair and bi-directional cavopulmonary shunt from January 1999 to June 2003. Methods Of 18 patients, 10 male (55.6%) and 8 female (44.4%), mean age was (18.47?13.85) years old (range from 9 months～54 years old),and mean weight of body (36.09?19.78) kg (range from 8.5～80.0 kg). All patients were in type II of Ebstein's anomaly according to WANG (Zenwei's) classification, while 15 (83.3%) were in type B, and 3 (16.7%) in type C according to Carpentier's classification. Danielson repair of Ebstein's malformation and other intracardiac repair were performed on all patients, followed by bi-directional cavopulmonary anastomosis, on pump with heart beating. Results There was no death, and no severe heart dysfunction and refractory low cardiac output in all patients postoperatively. No reoperation for residual or recurrent tricuspid incompetence was required in all patients. At follow-up of 13 (72.2%) patients ranging from 1 to 53 months, 12 patients were in New York Heart Association ((NYHA)) class I, 1 in class II. Four were with 1 grade, 2 with 2 grades tricuspid regurgitation. The patency of bi-directional cavopulmonary anastomoses was verified by echocardiography. Conclusion Ventricular unloading added to intracardiac repair appears to be effective to improve left and right ventricular function and tricuspid valve performance in Ebstein's anomaly with moderate or massive tricuspid dysfunction and physiological right ventricular outlet tract obstruction.

Objective To study the relationship between ? 1-aderenergic receptor (? 1-AR) and cardiac function in hypoxic newborn guinea-pig myocardia undergoing ischemic reperfusion, and the effects of St. Thomas Hospital cardioplegic solution Ⅱ (STS) and cold blood cardioplegia (CBC) on the ? 1-AR and cardiac function. Methods Normobaric hypoxic guenia-pig model and isolated perfused working heart preparation were established. Cardiac functions were recorded by a multichannel biologic signal analyzer. Myocardial ? 1-AR density (B max ) and affinity (K d) were investigated by radial ligand binding. Results Significant decrease of B max was found in hypoxic newborn guinea-pig myocardia suffering from hypothermic (20 ℃)-ishemic reperfusion (P0.05). Conclusion The impairment of cardiac function in hypoxic newborn guinea-pig undergoing myocardial ischemic reperfusion might be associated with the decline of B max , but not with K d. Different effects of STS and CBC on cardiac function may result from their different influences on B max .
