Objective To evaluate the feasibility and clinical efficacy of laparoscopic nephron-spring surgery for renal tumor.Methods From September 2004 to November 2006,29 patients with renal tumor underwent laparoscopic nephron-sparing surgery without hilar clamping or with temporary hilar control in our hospital.The retroperitoneal approach was used in 25 patients with 4 trocars.During the operation,the renal artery was exposed and then the vessel bundles were pulled out of the abdominal cavity through one of the trocars,passing by the renal artery without clamping it.Afterwards,fatty cysts surrounding or on the surface of the tumor were resected.Tumor excision was then performed using ultrasonic shears.An incision was made at the point 0.5 cm away from the margin of the tumor,and was extended deeply to completely cut the tumor.Meanwhile,bleeding was controlled with bipolar diathermy.The renal artery was occluded when necessary so that the tumor could be cut within a limited time duration.And the occlusion could be re-opened after controlling the bleeding.After the procedure,the renal incision was compressed with gauze,sutured with 2-0 absorbable sutures,and covered with fibrin sealant.In the other 4 patients,trans-peritoneal approach was used.The ureter was exposed near the lower pole of the kidney and separated towards the renal hilum to find out the renal artery.The following steps were similar to the above mentioned. Results In all the patients,the procedures were done without conversion to open surgeries.In this series,20 operations were completed without clamping the renal artery;and in the other 9,the mean time of renal artery occlusion was 14 min(5-20 min).In our patients,the mean operation time was 165 min(105-240 min),and the mean blood loss was 90 ml(20-800 ml).Two of the patients received blood transfusion during the surgery.The mean postoperative hospital stay was 9 d(7-17 d).No complications,such as urine leakage,occurred after the operation.Eighteen patients were followed up for a mean of 9 months(1-26 month),no recurrence of tumor was found.Conclusion Laparoscopic nephron-sparing surgery without hilar clamping or with contemporary hilar control is feasible and safe for patients with peripheral renal tumor not involving the renal collecting system.

Objective To explore the value and efficacy of retroperitoneal laparoscopic adrenalectomy.Methods From August 2002 to December 2007,a total of 401 cases of retroperitoneal laparoscopic adrenalectomy were performed in our hospital.Among the cases,nonfunctioning adenoma was diagnosed in 151 patients;hyperaldosteronism was detected in 139,Cushing’s syndrome in 37,pheochromocytoma in 19,myelolipoma in 13,and other diseases were found in 42.Results Among the cases,5 were converted to open surgery because of difficulties in the operation due to a huge tumor(1),extensive adhesion between the tumor and the inferior vena cava(2),or massive bleeding(2).The other 396 cases of retroperitoneal laparoscopic adrenalectomy were completed successfully with a mean operation time of 105 minutes(30 to 270 minutes),and a median blood loss of 45 ml(20 to 1000 ml).Two of these patients had massive hemorrhage(1000 and 800 ml respectively),and received red blood cells transfusion(2 U) during the surgery.The rupture of the inferior vena cava or diaphragm occurred in two cases,and was repaired under a laparoscope.Follow-up was available for up to 1 to 64 months(mean 23.9) in 364 patients;none of them had long-term complications or recurrent benign tumors.Conclusions Retroperitoneal laparoscopic adrenalectomy should be used as the first choice for benign adrenal neoplasms,since the procedure is safe,effective,and minimally invasive,and the patients recovery quickly after the surgery.

Aim To investigate the effect of procyanidins on apoptosis in brain of experimental rats with intracerebral hemorrhage(ICH) and its possible mechanisms.Method Rat intracerebral hemorrhage model was established by injecting collagenase into the brain caudate nucleus.Fifty-four health Sprague-Dawley rats were divided into six groups randomly: sham operation group,model group of intracerebral hemorrhage,treatment groups with procyanidins at doses of 50 mg?kg~-1,100 mg?kg~-1 and 200 mg?kg~-1,and positive control group with nimodipine at dose of 10 mg?kg~-1.Twentyfour hours after operation,the content of glutathione(GSH) and activity of catalase(CAT) were measured.The levels of bax and bcl-2 were detected by method of immunohistochemistry,and the apoptosis in brain tissues was detected by method of TUNEL.Result In procyanidins groups(50,100 and 200 mg?kg~-1),the content of GSH and the activity of CAT were significantly higher than those in ICH group(P

Objective To report the initial experience and results of the laparoscopic radical cystectomy (LRC) with ileal conduit. Methods Seven male patients with invasive bladder carcinoma confined to the organ underwent LRC with ileal conduit. The mean age was 61 years (range, 53 to 74 years). The procedure included radical cystectomy with prostatectomy. A 7 cm suprapubic incision was made to remove the organs. Ileal conduit was done routinely. Results Operating time was 7 to 10 hours (median 9.2), and blood loss was 200 to 400 ml (median 264). None of 7 patients needed blood transfusion. 2 to 10 months after surgery, intravenous urography showed no evidence of ureteral reflux or ureteral obstruction. Conclusions With the improvement in the surgical technique, laparoscopic radical cystectomy with small incision, resulting in rapid recovery, may become an alternative method for patients with localized bladder cancer with invasion to muscular layer.

The characteristics and rules of acupoint selection of acupuncture for trigeminal neuralgia were analyzed. By searching CNKI, VIP, WF, literature regarding acupuncture for trigeminal neuralgia from 1980 to 2013 was collected to establish an acupuncture prescription database. The data mining technology was applied to analyze the characteristics and rules of the acupoint selection. As a result, a total of 180 papers were included, involving 148 acupoints. It was found that the acupoints that had high frequency of selection included Hegu (LI 4), Xiaguan (ST 7), Fengchi (GB 20) and trigger points. The acupoints selected were distributed in 14 meridians, in which yangming meridian of hand-foot had a frequency of 41. 58%. The special acupoints including crossing points, yuan-primary points and five-shu points were widely used, accounting for 65. 9%. As for the branch of trigeminal nerve, the top-3 selected acupoints were Yangbai (GB 14), Yuyao (EX-HN 4), Cuanzhu (BL 2) in the first branch, Sibai (ST 2), Quanlian (SI 18), Yingxiang (LI 20) in the second branch, Jiache (ST 6), Xiaguan (ST 7), Dicang (ST 4) in the third branch. In conclusion, it is believed that the clinical treatment of trigeminal neural gia focuses on local acupoints in combination with nerve distribution-based acupoints and distal acupoints, also the special acupoints are emphasized.

Objective Rheological properties and gelation properties of agar were investigated. Methods The gelling point,melting point and the gel strength of agar were detected with MCR101 rheometer and TA texture testing instrument. Results and Conclusion Rheological properties of agar were affected by its concentration ,temperature and the addition of salt (such as NaCl ,CaCl2) and sucrose. Apparent viscosity exhibited shear thinning behavior following the power law model. Apparent viscosity increased with the increase of concentration,and decreased with the rise of temperature. The decrease in viscosity followed an Arrhenius temperature dependence. Agar solutions exhibited typical "weak gel" properties by small strain oscillatory measurements. The results indicated that the agar solution was characterized as a gel properties ,and which could form a kind of heat reversible gel. The gelling point of agar was lower than its melting point. The gel strength of agar could be affected by its gel time,and the addition of salt (such as NaCl,CaCl2) and sucrose.
