A canine model of sudden coronary death was established by intimal sur-face anodal direct current stimulation of the left circumflex coronary artery (LCX)on 5-8 days after the left anterior descending coronary artery (LAD) infarction. TheLCX intimal injury and subsequent thrombus formation produced ECG ST segment chan-ges at 104?30 minutes (X?SD), followed by premature ventricular beats, ventriculartachycardia (VT), and ventricular fibrillation (VF) in all normal saline (NS) treated dogs(n=6), in procainamide (PA) treated dogs (n=6), ECG ST segment changes appearedat 110?40 minutes, followed by VT and VF in only one dog (P

Objective To evaluate the clinical efficacy of percutaneous nephrolithotomy (PNL) in combination with pneumatic and ultrasonic lithotripsy in the treatment of complex renal calculi. Methods Under general anesthesia,an ureteral stent was placed into the patient by cystoscopy. With the prone position,percutaneous access was established by inserting an access needle into the intended calix under the guidance of ultrasonography or fluoroscopy. Afterwards,combined pneumatic and ultrasonic probes were used by nephroscopy for lithotripsy. Results A single tract was used in 137 patients,while two or three tracts were created in the other patients (11 and 2 respectively). One-step procedure to remove the stones was achieved in 119 patients,while a second intervention was performed in 27,and three procedures was carried out in 4. The mean time of the operations were (88?34) min. After the operation,one patient developed infectious shock,and then was cured by anti-shock therapy;two patients showed secondary hemorrhage in two weeks postoperation,and was cured by conservative therapy. In this series,the rate of stone clearance was 84.7% (127/150);23 cases had residual stones,10 of them received ESWL (the stone was removed completely in 7 of the 10 cases),and the other 13 were treated by oral medicines. Six months after the operation,follow-up examination showed a stone-free rate of 89.3% (134/150). Conclusion Combination of ultrasonic and pneumatic intracorporeal lithotripsy is effective and safe for complex renal calculi,which is intractable by open surgery.

Objective To develop stress vulnerability prediction scale for soldiers.Methods 148 items were determined by reviewing items in relating literatures and scales,interview,panel discussion and expert consultation.Then 431 and 351 soldiers in two times were picked out randomly as samples from Army Northwest District.Item analysis,exploratory factor analysis,reliability analysis and confirmatory factor analysis were used to analyse the data.Results Stress vulnerability prediction scale comprised five subscales:traumatic events,positive affect,negative trait,negative coping and interpersonal support.The scale was comprised of 59 items,and the factor loading of the items ranged from 0.503 to 0.839.Cronbach's α coefficient of the five subscales were 0.777,0.903,0.923,0.882,0.908,and the Cronbach's α coefficient of the scale was 0.895.Confirmatory factor analysis showed a higher goodness of fit(RESEA =0.058,NFI =0.89,NNFI =0.93,CFI =0.94,IFI =0.98).Conclusion Stress vulnerability prediction scale in soldiers has good psychometric properties,and can be used as a prediction measurement tool for measuring the stress disorder for soldiers.

Objective To assess the efficacy and safety of tolterodine on late-onset overactive bladder symptoms after prostate brachytherapy due to prostate carcinoma.Methods Twenty-six prostate cancer patients diagnosed by biopsy,who underwent prostate brachytherapy using iodine-125,were recrui(t)ed in this trial.All cascs complained of overactive bladder symptoms 6 months postoperatively.The 26 patients were divided into 2 groups:14 men in tolterodine group (TR group) who were given tolterodine 2 mg twice a day; 12 men in tamsulosin group (TS group) who were given tamsulosin 0.2 mg once a day.Efficacy was assessed by changes in IPSS,OABSS and nighttime voiding at 2 weeks and 4 weeks after medical treatment respectively.Safety was assessed by postvoid residual (PVR) and acute urinary retention (AUR),dry mouth,constipation and tachycardia at the fourth week after medical treatment.Results The age,tumor staging,GS,PSA,initial prostate volume,IPSS,OABSS,nighttime voiding,iodine-125 seeds implanted and needles punctured of both groups were comparable.IPSS,OABSS and nighttime voiding were significantly improved in TR group after 2 weeks of medical treatment and the above parameters were significantly improved than TS group (14.4 vs 18.3,5.9 vs8.4,1.4 vs2.5).OAB symptoms of TR group were also significantly improved than TS group after 4 weeks of therapy.There were no significant differences of PVR and AUR,dry mouth,constipation and tachycardia between both groups.Conclusions Tolterodine is effective and safe in treating late-onset OAB symptoms after prostate brachytherapy,although the occurence of dry mouth and tachycardia might be increased.

Objective To investigate the relationship between metabolic syndrome (MS) and recurrence of urolithiasis.Methods A retrospective analysis was performed in urinary stone patients from March 2008 to February 2012.Patients were divided into MS group and non-MS group according to the diagnose criteria of metabolic syndrome (2007 version) by the joint committee for developing Chinese guidelines on prevention and treatment of dyslipidemia in adults.The patients were followed up for 24-72months (median 47 months) since operation.The difference of stone recurrence was compared between the 2 groups.Results Two hundred and eighteen patients with urinary stone disease were enrolled.Of them,52 patients were diagnosed with MS.Stone recurrence occurred in 29 patients (55.8％) of MS group,whereas 66 patients (39.8％) of non-MS group suffered stone recurrence.It demonstrated the median recurrence free survival of group MS and non-MS was 36 months and 59 months by Kaplan-Meier analysis,respectively (Log-rank test,P =0.019).Multivariate Cox regression analysis results revealed that MS was significantly associated with stone recurrence (HR 1.817,95％ CI 1.105-2.988,P =0.011),however,the gender (P =0.336),age (P =0.246) and recurrence urolithiasis at first visit (P =0.051) were not associated with stone recurrence.Conclusions MS is an independent risk factor for urinary stone recurrence.It is suggested that the treatment of MS may have a important role in prevention of stone recurrence in MS patients with urolithiasis.

A canine model of electro-physiologic-electropharmacologic testing on ischemic ventricular tachyarrhythmias were established in the open-chest dogs subjected to programmed electrical stimulation (PES) on 5~8days after acute my-ocardial infarction produced with two -stage occlusion of left anteriol decending coronary artery (LAD) followed by partly reperfusion. The electrophysiologic -electropharmacologic effects of pro-cainamide (PA ) were observed in this canine model. pA distinctly lengthened the QTc interval and the effective refractory period ( ERP) of normal and infarct myocardium in both ventricles and decreasedthe dispersion of ERP in infarct myocardium (IDR) as well as the dispersion of ERP in left ventricle (VDR). The PES - induced ventricular tachycardia (VT) or ventricular fibrillation (VF) was prevented in 5 out of 6 PA treated dogs (n = 6),Normal saline (NS) did not prevented PES- induced VT/VF. The results suggest that PA may be effective in preventing the onset of reentrant ventricular tachyarrhythmias after myocardium ischemic damage.

Objective To compare outcomes of laparoscopic radical prostatectomy (LRP) and open radical prostatectomy (ORP) performed in our hospital.Methods A non-randomized,retrospective comparative study was performed to analysis 302 prostate cancer patients from January 2011 to June 2014.One hundred and ten patients underwent LRP and 192 underwent ORP.There were no significant differences between the LRP and ORP groups with respect to patient age,body mass index,PSA level,Gleason Score,clinical T stage and transrectal ultrasonography prostate volume (P ＞ 0.05).The operating time,estimated blood loss,catheter retaining time,hospital stay time,positive surgical margin rate and urinary control rate were compared between the 2 groups.Results The median operative time of the ORP group and the LRP group was 95 min and 120 min,the difference between groups was significant (P ＜ 0.01).The median duration of hospitalization of the 2 groups was 9 d and 6 d,the difference between groups was significant (P＜0.01).ORP group and LRP group's estimated blood loss was 350 ml and 250 ml.Days of tube drainage were 3 d in both groups.Days of urinary catheterization drainage after surgery were 16 d and 15 d,respectively.Positive margin rate was 10.4％ and 12.7％.Urinary continence recovery rates at 3 month were 80.2％ and 70.8％.Urinary continence recovery rates at 6 month were 85.9％ and 87.3％.No significant difference was observed in the above index (P ＞ 0.05).Conclusions Compared with ORP,LRP has shorter hospital stay time and longer operating time.Both LRP and ORP have good outcomes in oncological control and function rehabilitation.Both of them are important procedures to treat localized prostate cancer.

Objective To evaluate the efficacy and safety of sunitinib in patients with metastatic renal cell carcinoma. Methods Twenty-three male patients and 8 female patients were included in this study.All patients were metastatic renal cell carcinoma with prior radical nephrectomy or biopsy.Patients received treatment with sunitinib in repeated 6-week cycles,consisting of 4 weeks of 50 mg daily sunitinib administration followed by 2 weeks off treatment(schedule 4/2).CT scan was used to evaluate the efficacy every 2 cycles. Results Twenty-four of the patients could be evaluated the efficacy.None of them achieved complete responses,5 achieved partial responses,15 were in stable and 4 were with disease progression including 1 death.Four patients were forced to stop treatments because of poor general condition,lack of financial support or hepatic injury.Three cases could not be evaluated because of no long enough follow-up.The objective response rate was 21%(5/24)and disease control rate was 83%(20/24).The common adverse effects included hand-foot syndrome,diarrhea,anorexia,stomatitis,hemorrhagic tendency and hematotoxicity.But almost all of them were curable by using adjuvant drugs. Conclusions Sunitinib is efficient in the treatment of metastatic renal cell carcisoma.Most of the side effects are tolerable or curable.

Objective To explore the life quality of postoperative patients after a hypertensive cerebral hem-orrhage in the basal ganglia and the factors influencing it, so as to provide evidence for improving the life quality of such patients. Methods A total of 128 patients were studied retrospectively. Their gender, age, occupation, mari-tal status, education level, place of residence and family size were tabulated, as well as whether or not they were liv-ing with their children, smoking or drinking alcohol. Their household income was recorded along with their clinical condition during surgery ( midline shift, blood loss, operative time, whether a hernia occurred, consciousness, and whether bleeding broke into the ventricles. The SF-36 health measurement scale was used to evaluate the patients′life quality, and the factors influencing it were analyzed. Results Univariate analysis showed that: ( 1) Their physio-logical functioning ( PF) and global health ( GH) were mainly affected by age, marital status, family size, midline shift, quantity of cerebral hemorrhage, occurrence of herniation, consciousness and whether the hemorrhage broke in-to the ventricles. (2) Their physiological role (RP) was influenced by marital status, education background, household monthly income, midline shift, consciousness and whether the hemorrhage broke into the ventricles. (3) Pain (BP) was mainly affected by marital status and family size. (4) Social functioning (SF) was closely related to marital status, family size, consciousness and whether hemorrhage broke into the ventricles. (5) Their mental health (MH) was main-ly affected by the amount of bleeding, whether they were living with their children, the operation′s duration and whether the hemorrhage broke into the ventricles. (6) Their emotions (RE) were influenced by their consciousness and whether bleeding broke into the ventricles. (7) Their vitality (VT) was affected by their marital status, smoking, consciousness and whether the bleeding broke into the ventricles. Multivariate analysis showed that whether the hemorrhage broke into the ventricles was the most influential factor. Family size was also influential. Conclusions Age, number of family members, whether they are living with their children, and whether hemorrhage broke into the ventricles are all influen-tial in predicting the life quality of survivors of hypertensive cerebral hemorrhage in the basal ganglia.
