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 correlation between hemorrhage in transurethral resection of prostate ( TURP) and cystospasm and psychonosema of the patients with hyperplasia of prostate. Methods All clinic data of 322 patients with hyperplasia of prostate who have had TURP from 2009 to 2013 were reviewed. These patients were divided into four groups according to the volume of hemorrhage( H):H<400 mL, 400≤H<600 mL, 600≤H<800 mL, H≥800 mL. The quantity of cystospasm and psychonosema was measured by three catego-ries:no symptom, light symptom without treatment, severe symptom with treatment. The differences of the four groups were compared through statistical methods. Results The incidence rates of cystopasm and severity degree of psychonosema were increased with the raise of hemorrhage . Conclusion There is a positive correlation between the incidence rates of cystopasm and psychonosema and the volume of hem-orrhage in the patients with hyperplasia of prostate who have had TURP.

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 To evaluate the efficacy and safety of retroperitoneal laparoscopic pyelolithotomy ( RLP) combined with holmium laser lithotripsy under flexible cystoscopy in the treatment of complicated nephrolithiasis. Methods The retrospective analysis was made on the clinical data of 37 patients who underwent RLP and holmium laser lithotripsy under flexible cystoscopy for complicated nephrolithiasis from January 2013 to January 2014. The clinic parameters involved basic data of patients,operational time,blood loss,post-operative hospital stay,the status of stone-free,perioperative complications,and the follow-up data of patients were observed. Results No patient was converted to open surgery. The mean stone size was (2. 8 ± 0. 9) cm in diameter,operational time was (89 ± 24) min,blood loss was (21. 3 ± 7. 7) mL,post-operative hospital stay was (6. 8 ± 1. 7) d,the stone removal rate in one session was 94. 6%. One case occurred urinary leakage,1 case occurred fever after operation,who were all recovered through conservative treatment. All cases were followed up at the sixth months after operation. Conclusion RLP combined with holmium laser lithotripsy under flexible cystoscopy is effective and safe for the treatment of com-plicated nephrolithiasis.

Objective To investigate the key points for management of subclinical and agonal types of penetrating cardiac trauma (PCT).Methods A retrospective analysis was conducted on clinical data of 135 PCT cases treated from January 2005 to March 2012.The cases were divided into subclinical type,clinical type (cardiac tamponade or hemorrhagic shock types) and agonal type.Managements of the two extreme types including subclinical type and agonal type were studied in groups.Results (1) Thirty cases of subclinical type failed to have timely diagnosis and treatment due to the withdrawal from inhospital observation,which resulted in 22 deaths.Eleven cases of subclinical type had timely diagnosis through in-hospital observation or cardiac exploration,but three cases died in operating room thoracotomy (ORT).There were 27 cases of agonal type,but 15 died in ORT and two died in emergency room thoracotomy (ERT).Of 67 cases of clinical type,seven died in ORT.(2) A total of 86 cases survived ORT or ERT after timely diagnosis or diagnosis through in-hospital observation plus cardiac exploration.In the meantime,sound recovery was observed in 3-24 months of follow-up.Conclusion Success rate in treatment of PCT can be enhanced by close observation and timely cardiac exploration for subclinical type PCT and by timely ERT and bleeding control for agonal type PCT.

Objective To investigate treatment and prognosis of patients with osteosarcoma of the extremities.Methods A total of 311 patients with osteosarcoma of the extremities,who had undergone treatment in our institute from 1998 to 2008,were enrolled in this retrospective study.Kaplan-Meier survival curve and Cox regression model were used to analyze the correlation between survival rate and variables including patients' demographics,chemotherapy,surgery,complications,and tumor metastasis.Results Among 311 patients,there were 206 males and 105 females,aged from 5 to 56 years (average,18.6 years).A total of 282 patients underwent aggressive or radical surgery,including 149 cases of limb salvage surgery and 133 cases of amputation surgery.One hundred and five patients underwent standard chemotherapy and 206 patients underwent non-standard chemotherapy.The 5-year survival rate was 57.4％ in patients treated with standard chemotherapy,36.3％ in patients treated with non-standard chemotherapy,16.8％ in patients with lung metastasis,50.7％ in patients without lung metastasis,56.6％ in patients who underwent limb salvage surgery,31.8％ in patients who underwent amputation surgery,44.6％ in patients with Enneking stage Ⅱ B and 33.1％ in patients with Enneking stage Ⅲ.For patients treated by amputation surgery,because non-standard chemotherapy which was performed in most of them and other confounding factors,the 5-year survival rate of them was lower.The Cox regression analysis showed that lung metastasis and non-standard chemotherapy were associated with inferior outcomes.Conclusion Neoadjuvant chemotherapy combined with aggressive or radical surgery could cure about 60％ of patients with osteosarcoma of the extremities.Lung metastasis and non-standard chemotherapy are risk factors that severely affect prognosis.

ObjectiveTo explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients to guide individualized inmunosuppressive therapy. Methods From Jan. 2008 to Jan. 2010, 30 recipients received living related kidney transplantation were successively and divided into 2 groups according to the strategies of the correction of the dosage of immunosuppressant, 15 in each group. The strategy of immunosuppressive therapy in both groups was Tac + MMF + Pred. The correction of the dosage of immunosuppressant in experimental group was conducted by recipient lymphocyte reaction with donor DC (LR) combined with Tac and MPA blood concentration monitoring. Only blood concentration monitoring of drugs was applied in control group. Examinations of liver and renal function, blood and urine routine as well as blood sugar were done monthly for 1 year. ResultsDuring the follow-up period, the rate of acute rejection in experimental group and control group was 13. 3 ％ and 46. 7 ％ respectively (P＜0. 05) ;the rate of infection in experimental group and control group was 6. 7％ and 40. 0％ (P＜0. 05)respectively; the adverse reaction rate in experimental group and control group was 13. 3％ and 46. 7％(P＜0. 05). There was no significant difference in the serum creatinine level between the two groups at each observation point. ConclusionThe application of combined recipient LR with donor DC and blood concentration monitoring of drugs in individualized irnmunosuppressive therapy is more comprehensive and accurate.
