Objective:The therapeutical effects of salpingocatheterism and the states of tubal function were studied after different middle ear operations and within different middle ear pathological changes.Method:Total 71 patients with tubal occlusion, 18 of myringoplasty, 20 of reconstruction of ossicolar chain followed tympanoplasty, 14 of combined approach tympanoplasty, 10 of radical mastoidectomy followed tympanoplasty, 9 of re-radical mastoidectomy followed tympanoplasty were implemented salpingocatheterism. The patients were followed up for evaluation of the postoperative therapeutical effects and the state of tubal function. Result:The causes of operation failure in different middle ear operations or different middle ear pathological changes had no significantly difference. The major cause for postoperative tympanic membrane perforation and tubal occlusion was the pathogenic damage being not cleared up thoroughly and/or there being nasal cavity or pharyngeal cavity pathogenic changes accompanied.Conclusion:Salpingocatheterism is effective for preventing eustachian tube postoperative adhesion.

Objective To investigate the rs501120 and rs17465637 gene polymorphisms,and their relationship with the risk of coronary heart disease(CHD)in Chinese Han population.Methods 775 CHD without treatment and 775 age and gender matched controls were selected for this study,the genotypes of two single nucleotide polymorphisms(SNP)rs501120 and rs17465637 were tested with TaqMan-MGB probes.Results There was no significant difference in the frequency of genotypes of the 2 SNPs between CHD group and control group(P ＞0.05).Stratified analysis showed that SNP rs501120 had significant protection with CHD in people younger than 60 years old(OR 0.4,95% CI 0.2-0.9,P ＜ 0.05)or people with diabetes(OR0.3,95%CI0.1-0.7,P ＜0.05).Conclusions The results suggested that rs501120 was tightly associated with CHD in people younger than 60 years or had diabetes.

Objective To observe the clinical curative effect of Semen Cassiae application on navel in treating essential hypertension. Methods Totally 1674 cases of hypertension, according to visiting sequence, were randomly divided into treatment group (864 cases) and control group (810 cases). The control group was given hydrochloride enalapril 10 mg orally, 2 times a day. The treatment group was treated with Semen Cassiae application on navel, replaced per 24 h. The two groups were treated with moderate exercise, reasonable diet, and the course was 6 months. The clinical symptoms, blood pressure, blood lipid and blood rheology of the two groups were measured before and after treatment. Results To compare the symptoms efficacy, total effectiveness of treatment group was 95.14%(822/864), the control group was 71.11%(576/810), there was a significant difference (P<0.01). To compare antihypertensive effects, the total effective rate of the treatment group was 95.60% (826/864), the control group was 73.46% (595/810), there was a significant difference (P<0.01). The change of blood pressure in the treatment group was significantly better than the control group (P<0.01). TC, TG, HDL-C, LDL-C and blood rheology of the treatment group was significant different between before and after treatment (P<0.01). Conclusion On the basis of western medicine, Semen Cassiae application on navel played a double effect of acupoint and drug. It is more effective in lowering blood pressure, improving the clinical symptoms, blood lipid and blood rheology indexes.

Objective To observe the effect of electroacupuncture on urodynamic alteration in rats after complete T10 spinal cord transection.Methods Thirty-one female Sprague-Dawley rats were divided randomly into a sham operation group (n=10),a model group (n=11) and an electroacupuncture (EA) group (n=10).The spinal cords of the rats in the latter two groups were completely transected at the T10 level.Pressure was applied to the rats'lower abdomens every day while in the EA group electroacupuncture with continuous wave electricity was applied to the guanyuan (RN4) and sanyinjiao (SP6) acupoints for 15 min.The treatment was carried out daily for consecutive 7 days.Urodynamic examinations were carried out after the treatment course had finished.Results At the 9th day after the operation,average residual urine volume and bladder capacity in the EA group were both significantly lower than in the model group.Residual urine volume and bladder capacity were lowest in the sham operation group.Average voided volume and voiding rate in the EA group were significantly higher than in the model group.The average voiding rate was highest in the sham operation group.The average vesical pressure of the urine leak point and bladder compliance of the EA group rats were significantly lower than those of the model group The average vesical pressure of the urine leak point and bladder compliance of the sham operation group were lowest of all.All of these differences were statistically significant at the 1％ level of confidence.Conclusion EA can improve the lower bladder's detrusor reflex state and urinary tract function soon after complete T10 spinal cord transaction,at least in rats.

Objective To evaluate the effectiveness of mirror therapy in treating the upper limbs of patients with stroke.Methods The PUBMED,MEDLINE,EMbase,Cochrane Central Register of Controlled Trials (CENTRAL),ISI Web of Knowledge,OVID,CNKI,VIP and Wanfang Data databases were searched for reports of randomized controlled trials (RCTs) of mirror therapy in the treatment of the upper limbs of patients with stroke from the date of establishment of each database to April 2012.The bibliographies of the studies retrieved were also searched.Two independent researchers evaluated the included studies using the risk of bias provided by Cochrane Library.The extracted data were analyzed using RevMan 5.1 software and version 3.6 of the GRAED profiler.Results Reports of 9 trials were discovered.Meta-analysis showed that compared to the group that didn't have visual feedback,mirror therapy did not significantly increase Fugl-Meyer assessment (FMA) (Upper Limb) scores after 4 weeks of treatment compared with groups that did not have visual feedback.Mirror therapy also did not significantly increase average scores on the action research arm test (ARAT) after 6 weeks of treatment.Mirror therapy did,however,increase average Brunnstrom stage scores for the hand after 4 weeks of treatment and at a 6-month follow-up.Mirror therapy did not increase average scores on the modified Ashworth scale (MAS) after 4 weeks of treatment,but increased MAS scores were observed at a 6-month follow-up compared with a group which had no visual feedback.Mirror therapy increased functional independence measure (FIM) self-care scores after 4 weeks of treatment and at a 6-month follow-up,and it also increased modified Barthel index (MBI) scores after 4 weeks of treatment.In the GRADE system,the scores of Brunnstrom stages for the hand after 4 weeks of treatment were of moderate quality,but those scores and the MAS scores at the 6-month follow-up were of low quality.The FIM selfcare scores after 4 weeks and at the 6-month follow-up and the MBI scores measured after 4 weeks were of very low quality.Conclusion This evidence shows that mirror therapy can improve upper limb function and quality of daily life to some extent after stroke.However,because of the limitations of the previous studies such as poor quality,different end points,different rating scales and different courses of stroke,more high-quality,randomized,controlled trials with larger samples are needed to evaluate the effectiveness of mirror therapy in the rehabilitation of upper limb function after stroke.

DNA damage repair (DDR) defects occurred in 8%-16% of metastatic castration resistant prostate cancer (mCRPC). DDR gene mutation was related to poorer prognosis. Patients with DDR gene mutation, especially BRCA1/2 mutation, showed high sensitivity to poly ADP-ribose polymerase inhibitor (PARPi) and platinum.

PURPOSE: This study aimed to evaluate the prognostic impact of lymphovascular invasion (LVI) in patients treated with radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: We collected data from 180 patients who were treated with RNU from 2005 to 2013 at our institution. The Kaplan-Meier method with log-rank test and Cox proportional hazards regression models were used for univariate and multivariate analyses. RESULTS: LVI was present in 28 patients (15.6%), which was associated with higher pathological tumor stage (p < 0.001), tumor necrosis (p=0.012), lymph node metastasis (p=0.017) and multifocality (p=0.012). On multivariate analysis, LVI was an independent prognostic factor of recurrence-free survival [RFS: hazard ratio (HR)=2.954; 95% confidence interval (CI)=1.539–5.671; p=0.001] and cancer-specific survival (CSS: HR=3.530; 95% CI=1.701–7.325; p=0.001) in all patients. In patients with node-negative UTUC, LVI was also a significant predictor of RFS (HR=3.732; 95% CI 1.866–7.464; p < 0.001) and CSS (HR=3.825; 95% CI=1.777–8.234; p=0.001). CONCLUSION: LVI status was an independent predictor in patients with UTUC who underwent RNU. The estimate of LVI could help physicians identify high-risk patients and make a better medication regimen of adjuvant chemotherapy.

Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.
