Objective: To investigate the quality of life of patients with chronic prostatitis. Methods: Two hundred patients were included and tested with WHOQOL-100 . Results: Compared with normal controls, the following aspects had no significant difference, including energy and fatigue, appearance and status, working activity, daily life and environment. There were significant difference to controls in other 6 fields and 20 aspects. The major factors that do harm to QOL include satisfaction on life, income and depression. Conclusion: It should deserve the clinician's attention that the QOL of patients with chronic prostatitis is greatly lower than that of the normal controls.

Objective To study the clinical features of gallbladder small cell carcinoma (GSCC),to improve the diagnosis and treatment of GSCC.Methods We retrospectively analyzed the clinical data of GSCC patients at our hospital from January 2000 to January 2012,and made a collective review of the literature.Results In this series,there were four female cases,one male case,the age at the first diagnosis was between 42-67,with the median age of 57.The main complain was pain and dis-comfort on the up and right abdomen.Tumor located in the bottom of gallbladder in 3 cases,and in the body in 2.Cholelithiasis was complicated in 4 cases.2 patients received radical resection of GSCC,followed by adjuvant chemotherapy of VP-16 and cisplatin,radioactive therapy in one.Postoperatively,these two were followed up for 45 and 32 mons with tumor free survival.3 cases received palliative resection,followed by adjuvant chemoradioactive therapy or intervention treatment,these three were followed up to 8,11,30 months respectively to their death for tumor recurrence.Conclusions GSCC is a rare disease,the initial symptoms are not often specific and easily misdiagnosed.The prognosis of GSCC is poor.

Objective To summarize and analyze the clinical feature,therapeutic mnethods and prognosis of colorectal small cell carcinoma.Methods From January 2000 to January 2012,15 patients of colorectal small cell carcinoma were analyzed retrospectively.Results There were 12 male cases,3 females.The age at diagnosis was between 39-71 years,with median age of 60.SCC located in the rectum in 12 cases,in the colon in 3 cases.The time from the onset of symptoms to final diagnosis was from 1 to 12 months.The diameter of tumors varied from 2.5 to 8.0 cm.13 cases received up-front surgery,including radical tumor resection in 6 cases,palliative resection in 7 cases,and neoadjuvant-chemotherapy followed by palliative resection in one case.The initial Ⅰ,Ⅲ B,Ⅳ B stage were 1 case,6 cases and 8 cases,respectively.The overall median survival time is 11 months,1,2 year's survival rate is 40.0％ and 20.0％,respectively.Conclusions Colorectal SCC is less common and the prognosis is poor.Multimodality management,with radical surgical resection of the primary lesion followed by standard adjuvantchemotherapy,affords good local disease control and a fair survival.

Objective To evaluate the accuracy of a novel echocardiographic three-dimensional automated software for the assessment of the aortic root in candidates for transcatheter aortic valve replacement(TAVR).Methods Four patterns(Lax,Lax-Res,Sax,Sax-Res) of 3D-TEE imaging of aortic root were gotten preoperatively in 18 patients with severe tricuspid aortic stenosis who were referred to our center for TAVR.The specialized 3D-TEE reconstruction software,eSie Valves,then automatically configured a geometric model of the aortic root from the images obtained by 3D-TEE and performed a quantitative analysis of these structures:the minimal diameter(Dmin),maximal diameter(Dmax),area and perimeter(Peri) of aortic annulus,height of the ostia of the left/right coronary artery above the aortic annulus(LOH/ROH).The echo dimensions were compared with the MDCT measurements.Results No statistically significant difference were found in above parameters between the ZOOM pattern (Sax-Res and Lax-Res) and CT measurements(all P>0.05).Lax-Res pattern measurements had good correlation with MDCT,with r valves of 0.81,0.77,0.89,0.84 for Lax-Res-Dmin,Lax-Res-Dmax,Lax-Res-Area,Lax-Res-Peri,respectively(all P<0.05).3D-TEE LOH/ROH had poor correlation with MDCT LOH/ROH (all r<0.7).Conclusions The new automatic 3D-TEE software allows modelling and quantifying the aortic annulus dimensions from 3D-TEE data in patients with tricuspid aortic valves,and Lax-Res pattern is recommended.Quantified assessment of LOH/ROH is not ideal and needs to be improved.

Objective: To compare aortic annular diameter measured by transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and multislice computed tomography (MSCT) in patients with severe aortic stenosis, and to evaluate the impact on selection of prosthetic valve type in transcatheter aortic valve implantation (TAVI). Methods: Clinical data of 138 patients with severe aortic stenosis referred for TAVI between January 2014 and June 2016 in our hospital were retrospectively analyzed.The difference of aortic annular diameter measured by TTE, TEE, and MSCT were compared.TTE was performed after TAVI to evaluate the accuracy of measurement before TAVI. Results: (1) Aortic annular diameter was (23.37±2.22) mm by TTE and (23.52±1.70) mm by TEE (P=0.12). Pearson correlation analysis showed that aortic annular diameter measured by TTE was correlated to that measured by TEE (r=0.87, P<0.05). (2)The long-axis diameter and the short-axis diameter measured by MSCT multiplanar reconstruction were significantly different ((27.86±2.87) mm vs. (21.91±2.53) mm, P<0.05). There was no significant difference between the mean of the long- and short-axis diameters and the diameter derived from cross-sectional area by MSCT ((24.92±2.38) mm vs. (24.84±2.25) mm, P=0.08). However, the diameter derived from the circumference ((25.35±2.34) mm) was significantly larger than the mean of the long- and short-axis diameters and the diameter derived from cross-sectional area by MSCT, and the difference were (0.43±0.62) mm and (0.51±0.62) mm respectively(both P<0.05). (3) Measurements of the aortic annulus diameter by MSCT including the mean of the long- and short-axis diameters, diameter derived from cross-sectional area, and diameter derived from the circumference were larger than the measurement by TTE and TTE (all P<0.05). (4) Implantation was successful in all patients.Moderate to severe paravalvular leakage was detected in 3 patients at 7 days post TAVI, and 1 patient developed severe prosthetic valve restenosis at 6 months post TAVI and received valve-in-valve implantation. Conclusions In severe aortic stenosis patients referred for TAVI, the aortic annular diameter derived from TTE and TEE measurements are smaller than that from MSCT.In the absence of a gold standard, selection of prosthetic valve type in TAVI procedure should rely on comprehensive considerations, which is of importance to get good clinical results for severe aortic stenosis patients underwent TAVI.

Objective:To compare the left ventricular (LV) reverse remodeling after transcatheter aortic valve replacement (TAVR) between patients with bicuspid aortic valve (BAV) stenosis and tricuspid aortic valve (TAV) stenosis.Methods:The data of patients who underwent TAVR procedure from March 2013 to December 2018 in the Second Affiliated Hospital of Zhejiang University were retrospectively reviewed. The patients were divided into BAV group and TAV group according to cardiac computed tomography. Echocardiographic parameters, including aortic valve peak velocity (Vmax), mean gradient (PGmean), effective orifice area(EOA), interventricular septum diastolic thickness (IVSd), left ventricular posterior wall diastolic thickness (LVPWd), left ventricular end diastolic diameter( LVEDd), LV mass index (LVMI), ΔLVMI%, left ventricular ejection fraction( LVEF) of the two groups at baseline, 1 week, 1 month and 1 year post TAVR procedure were obtained and compared.Results:①Compared with preoperative measurements, both groups showed decreases in Vmax, PGmean and increase in EOA at 1 week, 1 month, 1 year follow-ups(all P<0.05). No significant differences were found in Vmax, PGmean, EOA, moderate/sever perivalvular leakage(PVL), moderate/sever prosthetic-patient mismatch(PPM) between BAV group and TAV group at 1 year. ②Both groups showed decreases in IVSd, LVPWd, LVEDd at 1 month, 1 year post TAVR compared with those before the procedure (all P<0.05), as well as increases in LVEF at 1 week, 1 month, 1 year (all P<0.05). Downward trends of LVMI were detected in both groups within 1 year follow-up( P<0.05). ③Compared to TAV group, BAV group showed smaller baseline LVMI( P<0.05), while there were no significant differences in ΔLVMI% post TAVR for all follow-up times of the two groups(all P>0.05). Repeated measures analysis of variance also showed no significant differences in downward trend of LVMI between the two groups after TAVR within 1 year( P>0.05). Conclusions:Left ventricular reverse remodeling can be detected in both BAV and TAV patients after TAVR, which starts from 1 week and can be lasted for 1 year post procedure. Patients with bicuspid morphology might experience similar reverse LV remodeling post TAVR versus patients with tricuspid morphology.

Objective:To explore the value of transesophageal echocardiography(TEE) guidance for transcatheter DragonFly? system edge-to-edge tricuspid regurgitation (TR) repair.Methods:Five cases who were chosen in the Second Affiliated Hospital, Zhejiang University School of Medicine from December 2020 to January 2021 with surgical high-risk and severe functional TR underwent transcatheter DragonFly edge-to-edge repair with the guidance of TEE. Preoperative TEE was used to evaluate the tricuspid valve anatomy and the origin and etiology of regurgitation in detail; intra-procedure guidance of TEE was performed during the DragonFly system for tricuspid valve edge-to-edge repair intervention and after release of the DragonFly clip, the effect of surgery was assessed immediately and compared with pre-procedure TEE.Results:A total of 10 DragonFly clips were implanted in 5 patients (3 in each of patients, 2 in 1 patient, and 1 in each of patients). One of the 3 clips in 1 patient fell off unilaterally from the septal valve after release, and the other 9 clips were well positioned and fixed. Immediately post-operation assessment by TEE depicted the TR in 3 patients declined to mild and 2 to moderate. The vena contracta area by using three-dimensional color blood flow quantitative assessment was reduced[(0.93±0.26)cm 2 vs (0.20±0.11)cm 2]. No complications such as serious tricuspid valve injury, pericardial tamponade, thromboembolism occurred in the 5 patients. Conclusions:TEE plays an important role in guiding and monitoring transcatheter DragonFly system edge-to-edge TR repair during the entire procedure.

The effect of vitamin D supplementation on individuals with autism spectrum disorder (ASD) is inconclusive. We aimed to conduct a meta-analysis of the available randomized controlled trials (RCTs) to explore whether vitamin D supplementation can improve core symptoms and coexisting conditions in children with ASD. Data were obtained by searching the PubMed, Embase, Web of Science, CINAHL and Cochrane Library databases up to February 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Using a random-effects model, mean differences with 95% confidence intervals (CIs) were calculated through a meta-analysis. There were eight RCTs with 266 children with ASD in the present review, among which six RCTs were included in the meta-analysis.Children who received vitamin D supplementation showed a significant improvement in stereotypical behavior scores (pooled mean difference (MD): −1.39; 95% CI: −2.7, −0.07; p = 0.04) with low heterogeneity (I2 = 34%), and there was a trend toward decreased total scores on the Social Responsiveness Scale (SRS) and Childhood Autism Rating Scale (CARS, p = 0.05); however, there were no other significant differences in the core symptoms of ASD and coexisting conditions between groups as measured by the Aberrant Behavior Checklist (ABC). Vitamin D supplementation appears to improve stereotypical behaviors but does not improve other core symptoms and coexisting conditions. Further randomized controlled trials with large sample sizes and individualized doses are needed.

Objective:To explore the safety of transanal re-excision (TAR) after positive-margin local resection for early rectal cancer.Methods:A retrospective analysis was made data of 44 patients with rectal cancer after local excision from Mar 2006 to Oct 2018 at the Department of Colorectal Surgery, Cancer Hospital of Chinese Academy of Medical Sciences. All patients had positive margin or suspicious tumor remains after local excision, and subsequently salvage TAR surgery was performed after informed consent was given.Results:Forty-four patients after local excision were with pathologically showed residual condition, including 26 cases of positive margin and 18 cases of suspicious tumor remaining. The pathological types were all adenocarcinoma. Forty-one (93%) patients with pT1 and 3 (7%) patients with pT2. The median follow-up time after salvage TAR was 100 (11-164) months. During follow-up, 3 patients (7%) developed mild anal incontinence. One patient (2%) had local recurrence, 3 (7%) patients had distant metastases, and 3 patients (7%) died of non-tumor specific deaths. The overall 5-year survival rate and disease-free survival rate were 98% and 93 %, respectively.Conclusions:Transannal full thickness tumor re-excision is safe and reliable for the salvage treatment after non-complete local resection of early rectal cancer. The long-term follow-up results show that the 5-year survival rate is comparable to that of radical surgical resection, and with a good anal function.
