ObjectiveTo investigate the clinical efficacy and safety of solifenacin for female overactive bladder (OAB) who failed in toherodine treatment. MethodsFrom Jan 2010 to Oct 2010,48 cases of female OAB were treated with 5 mg/d solifenacin for 4 weeks after the failure of tolterodine treatment.The improvement of the perception of bladder condition as well as the mean numbers of day-time micturition,urgency episodes,urge incontinence episode per day,nocturia and pads usage were used as objective indexes for the evaluation of therapeutic effect. ResultsAfter 4-week solifenacin treatment,the mean numbers of day-time micturition,urgency episodes,urge incontinence episode per day,nocturia and pads usage were respectively decreased from the baselines ( 8.7 ± 1.5),(3.4 ± 2.1 ),( 2.4 ± 1.8 ),(2.1 ± 1.8 ) and (2.2 ±1.6) to be (7.2 ±2.5),(2.0 ±1.8),(1.5 ±1.2),(1.2 ±0.8) and (1.4 ±0.8).The perception of bladder condition was improved in 42 cases.The withdrawal from the treatment was seen in 3 cases due to headache and dry mouth.No severe adverse event was found in the rest 45 patients. Conclusion Solifenacin might be an effective and safe alternative agent in the treatment of female OAB who failed in tolterodine treatment.

Objective To explore the clinical significance of B7 family homology factor-3 (B7-H3),an expression membrane type of myeloid-derived suppressor cell (MDSC),in patients with acute pancreatitis (AP).Methods A total of 63 patients with AP initially treated in the Emergency Department at the First Affiliated Hospital of Soochow University from January,2014 to December,2015 were selected.Of them,25 suffered from mild AP (MAP),20 had moderate AP (MSAP) and 18 had severe AP (SAP).Another 20 healthy subjects with matching age and gender served as the control group.All patients with AP conformed to the diagnostic criteria of Guidelines or Diagnosis and Treatment of Acute Pancreatitis set in 2013 in China.Patients with other underlying diseases that might influence the clinical outcomes were excluded,including those with tumors,autoimmune diseases,viral infections,trauma and other disorders.A flowcytometer was used to detect the expression rate of MDSC in peripheral venous blood and the expression of B7-H3 on MDSC membrane.The continuous monitoring was carried out for 24 h,48 h and 72 h in patients with AP.Results Compared with healthy subjects,the MDSC cells in patient groups 24 hours after AP onset increased notably (P ＜0.01) especially the highest increase in the SAP group,followed by the MSAP group and the lowest in the MAP group.There were significant differences in pairwise comparisons (P ＜ 0.05).From successive observation of each group,there was no significant difference in MDSC between the MAP group and the MSAP group 24 hours,48 hours and 72 hours after AP onset.However,MDSC reached its peak 48 hours after AP onset,but it declined 72 hours after AP onset in the SAP group (P ＜ 0.05).B7-H3 expressed significantly 24 hours after AP onset,but there was no expression of B7-H3 in the healthy group.Meanwhile,B7-H3 was expressed most highly in the SAP group,followed by the MSAP group and lowest in the MAP group.There were significant differences in expression of B7-H3 found in pairwise comparisons (P ＜ 0.05).The successive observation showed that there was no significant difference in B7-H3 expression between the MAP group and the MSAP group 24 hours,48 hours and 72 hours after AP onset.However,there was a trend of increase in B7-H3 expression as time prolonged found among 24 hours,48 hours and 72 hours after AP onset in the SAP group (P ＜ 0.05).Conclusions The expressions of MDSC and B7-H3 were high in AP,and there were significant differences in both expressions among MAP,MSAP and SAP groups.These phenomena offer clues in further understanding about the immunological disorders during AP giving better guidelines for clinical practice.

Objective To investigate the safety and feasibility of en-bloc resection of a primary sacral chordona based on a 3-dimensional printing model.Methods 31 patients with primary sacral chordoma underwent en-bloc resection via a onestage posterior approach or combined anterior and posterior approaches in our oncology department from January 2013 to December 2014.They comprised 21 males and 10 females of mean age (49.2±12.5) years (range,26-67 years).Preoperative 3-D printing models were created by 3D printing technology,it included tumor tissue,the around vascular and nerves involved in sacral chordoma.The sacral chordomas were en-bloc resection with decompression and internal fixation.Results With the mean (29.0±6.8)months follow-up (range from 19 to 41),all patients underwent en bloc excision via 26 cases with posterior approach,5 cases combined posterior and anterior approaches in one stage.The mean operative time and estimated blood loss were (275.0±58.1) min and (3 250.0±1 304.4) ml,respectively.The visual analogue scale (VAS) score was (5.6±1.9) in average (range from 3 to 9) at preoperation,and (2.0±1.5) at post-operation,which was significantly lower than that of preoperation,and the pain was relief obviously.There were 13 cases in grade C,11 cases in grade D,7 cases in grade E of American Spinal Injury Association (ASIA) grade neurological function before surgery,compared with the pre-operation,there were 5 cases in grade C,6 cases in grade D,20 cases in grade E of post-operation,which was significantly improved.MSTS (Musculoskeletal Tumor Society) 93 score was 6-29 points (20.0％-96.7％) at the follow-up 3 months after surgery,with the average of (19.8 ± 5.8) points,which excellent in 8 cases,good in 14 cases,general in 5 cases,poor in 4 cases.Two cases of dysporia for the reasons of resecting on one side of the S1,2 nerve roots involved by the sacral chordoma,after sacrificing the nerve root of complete tumor resection,the urine left dysfunctional,while the pain of other 29 patients were thoroughly relief after surgery.The ones were relieved with the disturbance of sensation of the perineum before the operation.2 cases were recovery of leakage of cerebrospinal by the drainage of lumbar cistern with normal temperature.One hypostatic pneumonia patient was cured by anti-inflammatory.One with the urinary infection got better by the effective bladder irrigation,which had diabetics mellitus with the bladder stoma before.1 case of skin necrosis due to vascular thrombosis before operation,recevied flap translocation half month after surgery,got recovery 3 months later.Only one underwent tumor resection for the recurrence at 15 months follow-up.Conclusion It is feasible and safe to perform en bloc resection of primary sacral chordoma.This is the most effective means of managing method of the marginal resection of the tumor.Preoperative 3-D printing modeling enables better anatomical understanding of the relationship between the tumor,and can avoid vascular and nerves tissue injury,which can also assist in planning the surgical procedure,and be worth recommendation.
