Objective To introduce and evaluate the procedure of suprapubic tensionless Sparc TM sling system in treating female stress urinary incontinence (SUI). Methods A total of 42 patients (mean age,54 years) diagnosed with SUI (a mean course of 12 years) were treated by Sparc TM sling method.Of them 4 cases had detrusor instability.Under local anesthesia,this procedure took about a mean of 20 min.The urinary catheters were removed the next morning after the procedure.The patients were counseled on abstaining from heavy lifting,exercises and intercourse for 4 weeks. Results After removal of catheters,all the 42 patients successfully voided without incontinence.Detrusor instability to various degrees developed in 7 patients and was relieved by expectant treatment.All the patients were followed up for 3 to 12 months (mean,6 months).Neither recurrence of SUI nor lower urinary tract obstruction was found.No implant related complications such as local irritation,extrusion,erosion through the urethra,migration from the desired location,fistula formation and inflammation occurred. Conclusions Sparc TM sling system is a simple,safe and efficacious method of treating SUI under local anesthesia.

Objective To study the role of cell apoptosis during the chemotherapy of human gliocytoma in order to get effective suvilliance on the effect of chemotherapy. Methods Gliocytoma cells were isolated and cultured from 40 human gliocytoma samples. Mitochondrial membrance potential (MMP), cell cycle, the level of Bcl-2 and Bax were detected by flow cytometry (FCM) at 24, 48, 72 hours respectively of incubation with Lomustine (CCNU) and Teniposide (VM-26), and the trends were also analysed. Results MMP decreased greatly, the apoptosis part in the cell cycle ananlysis increase, the expression level of Bcl-2 decreased, and that of Bax increase rapidly, while the Bcl-2/Bax ratio decreased. Conclusions CCNU and VM-26 have singnificant effect in gliocytoma chemotherapy on inducing gliocytoma cell apoptosis. VM-26 has more stronger effect on the cell cycle. MMP is the most sensitive and the fastest index in apoptosis detection.

Objective:This study was to study effect of keeping ying and weiqi in balance on cardiac muscular collagen Ⅰ,collagen Ⅲ,angiotensinⅡ in spontaneous diabetes rats,and provide new thoughts for prevention and treatment for diabetic cardiomyopathy.Methods:40 spontaneous diabetes rats were divided into four groups at random:spontaneous diabetes control group,diformin group,Guizhi Decoction group and Huanglian Jiedu Decoction group.Except control group,each group was given intragastric administration for 12weeks.Blood glucose,collagenⅠ,collagen Ⅲ,collagenⅠ/collagen Ⅲ,angiotensin Ⅱ were determined.Euzymelinked immunosorbent assay and radio-immuniy method were used.Results:Blood glucose in Huanglian Jiedu Decoction group and diformin group decreased;Compared respectively with diformin group and control group,collagenⅠdecreased obviously and collagen Ⅲ increased signifi cantly in Guizhi Decoction group,and the collagenⅠ/collagen Ⅲ decreased.Compared with diformin group and control group,cardiac muscular homogenate AT-Ⅱ contents decreased in both of Guizhi Decoction group and Huanglian Jiedu Decoction group.Conclusion:Guizhi Decoction can decrease the content of collagen Ⅰ,AT-Ⅱ and collagenⅠ/collagen Ⅲin cardiac muscular,and increase content of collagen Ⅲ,then prevent and treat cardiac muscular collagen reconstruction and myocardial fibrosis.Huanglian Jiedu Decoction can decrease the content of AT-Ⅱ,and decrease collagenⅠ/ collagen Ⅲ,collagenⅠ slightly,and can improve cardiac muscular collagen reconstruction.Keeping ying and weiqi in balance is a new thought for prevention and treatment for diabetic cardiomyopathy.

Objective To evaluate the feasibility and safety of endoscopic thyroidectomy via anterior chest and breast for the treatment of patients with papillary thyroid carcinoma ( PTC ).Methods Endoscopic thyroidectomy was performed in 85 PTC patients between March 2006 and March 2010. Diagnosis was based on intraoprative frozen section. There were 83 females and 2 males, age averaged at 36. 3 years. Sixty three of 85 cases were diagnosed preoperatively as thyroid carcinoma and US revealed ipsilateral cervical lymph node enlargement suspective of metastasis in 12 cases. Endoscopic thyroidectomy plus selective neck dissection was performed. Results This procedure was carried out successfully in 84patients. There were 51 cases of papillary thyroid microcarcinomas(<1. 0 cm) , 28 cases between 1. 0 cm and<2. 0 cm, and 5 cases with the diameter between 2. 0 cm and 3. 0 cm. Total thyroidectomy, ispilateral lebectomy and ispilateral lebectomy plus contralateral subtotal lobetomy were performed in 4, 6, 74 cases,respectively. Central compartment dissection was performed in all of the 84 cases and ipsilateral neck dissection was also performed in 12 cases that were suspected metastatic lateral neck lymph nodes. The mean operative time was (113. 3 ±46. 5) minutes. No significant blood loss occurred. The mean number of lymph nodes yield in the central compartment and lateral compartment were 6. 5 (range 2 to 14) and 19. 2 (range 9 to 26 ), respectively. Forty-four cases ( 44/84, 52. 4% ) had metastatic lymph nodes in central compartment, while 11 cases (11/12,91.1% ) in lateral compartment. Six patients (6/84,7.14%) had transient vocal cord palsy and recovered after 1-2 months. Postoperative transient hypocalcaemia occurred in 4 cases (4. 8% ) , and there were no other major complications. The average postoperative hospital stay was 3. 7 days (range 3 to 6). No evidence of residual or recurrent disease was found at follow-up. The cosmetic results of this procedure were excellent. Conclusions The anterior chest and breast approach of endoscopic thyroidectomy is feasible and safe and cosmetic worthwhile for selected cases of PTC.
