Objective To evaluate the long-term outcomes,complications and urodynamic parameters of using tension-free vaginal tape-obturator(TVT-O)in the treatment of patients with stress urinary incontinence.Methods Preoperative and postoperative evaluations including urodynamic data and quality of life were performed for 24 patients with stress urinary incontinence who were enrolled and treated with TVT-O between May 2007 and June 2011.Results Patients completed long-term postoperative follow-up from 12 to 60 months after surgery.Twenty-one(87.5％)patients achieved long-term subjective success and 22(91.7％)achieved objective success.Surgical satisfaction and quality of life was high.Long-term postoperative abdominal leak point pressure of 23 patient was greater than 100 cm H2O,and the remaining parameters preoperative and postoperative showed no significant differences.Voiding difficulty and external reflection voding desire were the main long-term complications.Conclusions TVT-O is with few complications and high patient satisfaction.It is a simple,safe and effective procedure for treatment of patients with stress urinary incontinence.Long follow-up period is important for the comprehensive evaluation of TVT-O.Postoperative urodynamic study has significance in complications,diagnosis and evaluation.

Objective To explore expression of Beclin1, autophagy-related protein 1 (Atg1), mammalian target of ra-pamycin (mTOR) in squamous cell carcinoma (SCC) and adenocarcinoma of lung and to analyse relationship among these three factors. Methods Immunohistochemical stainning was applied to detect expression of Beclin1, Atg1 and mTOR in 82 samples of SCC and adenocarcinoma of lung (lung cancer group) and 17 samples of paraneoplastic normal lung tissues (con-trol group). Correlations of expression of Beclin1, Atg1 and mTOR were analyzed in SCC and adenocarcinoma of lung. Re-sults The expression of Beclin1 was significantly lower in lung cancer group than that in control group(52.44%vs 94.12%, P＜0.01). There were significant differences of the differentiation, TNM stages and lymph node metastasis in lung cancer group compared with those in control group. And Beclin1 expression showed a decreasing trend with malignant and invasive of tumors. mTOR expression in lung cancer tissue with lymph nod metastasis is higher than that in the tissue without lymph node metastasis(P＜0.01). Atg1 expression in lung cancer tissue with larger mass is less than that in lung cancer tissue with small lumps(P＜0.01). Beclin1 Expression was positively correlated with the Atg1 expression in SCC(r=0.609,P＜0.01). Beclin1 and Atg1 expressions were both negatively correlated with mTOR expression in SCC(r=-0.617,-0.444,P＜0.01). Beclin1 expression was positively correlated with Atg1 expression in adenocarcinoma(r=0.458,P＜0.01). Beclin1 and Atg1 expression were both negatively correlated with mTOR expression in adenocarcinoma(r=-0.497,-0.541,P＜0.01). Conclu-sion Beclin1, Atg1 and mTOR expression showed a strong correlation in lung cancer, and clinicopathological change of lung SCC and adenocarcinoma may be related to autophagy.

Objective To explore the attentional biases in individuals with different types of obsessivecompulsive symptom and the correlations between the attentional bias of high obsessive compulsive symptom (HOC) and symptoms. Methods 22 individuals with HOC and 38 individuals with low obsessive compulsive (LOC) symptom completed the Chinese Emotional Stroop task that assessed the attentional bias. Comparisons were made between HOC and LOC and in different types of HOC, and the correlations between the attentional bias of HOC and symptom severity scores were searched for. Results The comparison between HOC and LOC on the reaction time of neutral, negative and disgust-related words were not significant. The contamination/washing subtype in HOC showed faster reaction time on negative and disgust-related words compared to that of neutral words,and its attentional bias exhibited significant correlation with symptom severity scores( r= -0. 648, P=0. 031 ). Conclusion Such information point out the contamination/washing subtype may have a different neural mechanism compared to the other subtypes of OCD.

ObjectiveTo explore the clinical outcomes of posterior lumbar interbody fusion using BTwin expandable spinal spacer with microendoscopic discectomy (MED) for lumbar disc herniation accompanying degenerative instability.MethodsFrom March 2006 to May 2010,87 patients with lumbar disc heniation (only one level) accompanying degenerative instability were managed with posterior lumbar interbody fusion using B-Twin with MED,includeing 49 males and 38 females with an average of 47.6 years(range,37-65).Objective level located in L3,4 in 2 cases,L4,5 in 43,and L5S1 in 41.The patients were treated with single BTwin(Single group,n=51) and double B-Twin(Double group,n=36).Clinical outcomes were evaluated with surgical time,blood loss,visual analogue scale (VAS) scores,Oswestry disability questionnaire (ODI),and the pre- and post-operative disk space heights.ResultsThe patients were followed up for an average of 35.8months (range,12-46).All the patients felt the low back pain and radiation pain disappeared or relieved apparently.The mean preoperative ODI and VAS scores decreased from 78％±3％ to 18％±3％,and (8.70±11.3)to (0.65±10.48) at the final follow-up respectively.Disc space increased from a pre-operative height of (8.76±1.3) mm to a post-operative of (11.8±0.6) mm.ODI,VAS and the disk space heights in all patient showed statistical significance,which revealed no statistical significance between the two groups.However,the operation time,blood loss were statistical difference between the two groups.All the patients achieved solid union or probable union at a mean time of 5.6 months (range,3.9-8.6).ConclusionPosterior lumbar interbody fusion using B-Twin with MED can obtain satisfactory outcomes in the treatment of lumbar disc herniation accompanying degenerative instability.Single B-Twin can get similar clinical outcomes,but shorter surgical time,less blood loss,and less medical costs.

Objective To study the clinical efficacy of intra-operative implantation of I125 seeds to treat advanced pancreatic cancer.Methods We retrospectively analyzed the clinical data of 28 patients who underwent intra-operative implantation of I125 between January 2009 and June 2010 to treat advanced pancreatic cancer.Patients who received conservative treatment (n =136) at the same period were used as the control group.Results The mean tumor diameter was (5.7 ± 1.7) cm.The average number of implanted seeds were 50.There were no patients who suffered from pancreatic fistula or post-operative bleeding,and no patient died from the treatment.Twenty-five patients were regularly followed up,and the follow-up rate was 85.7％.The survival rates at one month,half a year and one year were 100％,70.8％ and 26.9％,respectively.The average survival time was (9.9 ± 1.4) months.The survival data were significantly higher than that in the control group.Conclusion Intra-operative implantation of I125 seeds was an efficacious treatment for patients with advanced pancreatic cancer.
