Angiotensin (Ang Ⅱ),a main effector peptide of the renin-angiotensin system (RAS),mediates a hormonal action in the maintenance of blood pressure and electrolyte levels,and thus fluid homeostasis.Recent studies have implicated that it correlates with tumor growth,angiogenesis,metastasis and it has drawn more and more attention.Many studies show that Ang Ⅱ-AT1R/AT2R play crucial roles in tumor growth,metastasis,invasion and tumor angiogenesis,which are formed new targets for treating malignant tumors.

Objective To apply a hand function laserimager to evaluate the effect of acupuncture on hand dysfunction after stroke. Meth-ods From January to June, 2016, 18 stroke patients with upper limb dysfunction were divided into control group (n=9) and acupuncture group (n=9). The control group received routine medication and rehabilitation, while the acupuncture group received acupuncture in addi-tion. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limb motor function and modified Bathel Index (MBI) before and after three-week treatment, while the region of interest (ROI) of their hands was tested with the hand func-tion laserimager. Results The scores of MAS and FMA improved after treatment in both groups (t>4.44, P<0.01), and improved in the score of MBI in the acupuncture group (t=3.95, P<0.01). The scores of MAS, FMA, and MBI improved more in the acupuncture group than in the control group (t>3.17, P<0.01). Meanwhile, the scores of ROI decreased in the affected hands after treatment (t>7.78, P<0.001), and de-creased more in the acupuncture group than in the control group (t=-2.23, P<0.05). No significant difference was observed in the scores of ROI of the unaffected hands (t=-0.11, P>0.05) between groups. Conclusion The hand function laserimager, which responds to the blood perfusion of the hand, can be used as a tool to evaluate the hand function.

BACKGROUND: A long-term follow-up indicates that orthotopic ileal neobladder can cause acid-base balance and nutritional metabolic disorder. Otherwise, a long mesenterium is necessary to balance the tension of bladder at pelvic cavity and urinary inosculation due to a high position of ileum. On the contrary, sigmoid neobladder is near by urinary canal, and orthotopic sigmoid neobladder as a bladder substitute after radical cystectomy has few effects on acid-base balance of electrolytes, nutritional metabolism and secretion of mucus.OBJECTIVE: To compare the clinical results of these two operations basis on long-term follow-up. DESIGN: Retrospective analysis.SETTING: Department of Urinary Surgery, the Second Affiliated Hospital of Kunming Medical College.PARTICIPANTS: 164 patients with carcinoma of bladder were selected from Department of Urinary Surgery, the Second Affiliated Hospital of Kunming Medical College form January 1995 to March 2005. Ninety-six of them, including 74 males and 22 females, with age of 43-74 years and the average age of 65 years, accepted the operation of orthotopic ileal neobladder were regarded as the ileal neobladder group, and the other 68, including 64 males and 4 females, with age of 51-72 years and the average age of 62 years, accepted the operation of orthotopic sigmoid neobladder were regarded as the sigmoid neobladder group. All patients were finally diagnosed as pathological examination, and informed consent was provided by all patients. Treatment plan was approved by the local ethical committee.METHODS: ① Orthotopic ileal neobladder: Once the bladder was removed, a segment of ileum about 40-60 cm in length was isolated. In the operative procedure, the distal part of ileum which connected to the caecum often kept, the length of which was 15-20 cm. Both distal ends of the ureters were anastomosed to the homolateral not been split end of the isolated bowel. A perforation was constructed at the bottom of the pouch which served as the outlet, this outlet was then anastomosed to the proximal portion of the remaining urethra. ② Orthotopic sigmoid neobladder: After surgically removing the bladder, a part of the sigmoid colon, the length of which was 30-40 cm was isolated. Other operations were as the same as those mentioned above. MAIN OUTCOME MEASURES: Time of operation, blood loss during the procedure, length of time confined to bed, time of indwelling catheter, the ability to maintain continence and urinate, the results of urodynamic studies, and pouch related complications after operation.RESULTS: In 164 patients, 12 (7.3%) were lost to follow-up. The mean follow-up times were 46 months in the group of orthotopic ileal neobladder and 42 months in the group of orthotopic sigmoid neobladder, respectively. Blood loss during the procedure and the ability to maintain continence and urinate were similar in the two groups (P > 0.05). Compared with sigmoid neobladder group, the ileal neobladder group spent more time on operation, keeping the bed and indwelling catheter. The max volume of ileal pouch was higher than that of sigmoid pouch, and the difference was significant in statistic analysis (t=2.56-3.08, P < 0.05-0.01). Incidence of complication of ileal pouch (16.7%, 29.2%) was higher than that of sigmoid pouch (9%, 16%). The incidence in the early phase was not significantly different, but that in the late phase was significantly different (x2=5.426, P < 0.05).CONCLUSION: Compared with orthotopic ileal neobladder, sigmoid neobladder is worthy of being preferred for its shorter operative time, faster recovery and lower rate of pouch related complications.

Objective To explore the value of Artis zeego robot imaging system endoscopic retrograde cholangiopancreatography (ERCP) for biliary calculi. Methods ERCP was performed on 12 patients with biliary tract dilation, diagnosed by B ultrasonography. Artis zeego robot was used simultaneously to acquire 3D images and biliary system reconstruction. The diagnostic consistency was assessed based on endoscopy and surgery if necessary. Results 3D rotating acquisition and biliary reconstruction were performed in the 12 patients. All diagnosis coincided with those of surgery and ERCP findings, achieving a consistency rate of 100%. Patients with extrahepatic bile duct stones of uncertain number (n = 2), with suspected biliary duct calculi ( n = 1 ) and with suspected intrahepatic bile duct stones ( n = 2) under ERCP were all diagnosed by the robot imaging system. Conclusion During ERCP, 3D rotating image acquisition and biliary reconstruction with Artis zeego robot is helpful for precise diagnosis of biliary tract stones.

Objective To elucidate the diagnosis and treatment of the bladder mixed tumor.Methods 16 cases treated from Jun 1990 to Aug 2004 were reviewed.The clinical manifestations,diagnosis,treatment and prognosis were discussed.Correlative literature was reviewed at the same time.Results 16 cases of the bladder mixed tumor accounted for 6.9% of 223 bladder tumor patients in the same period,of which 7 of 16 were transitional squamous cell carcinoma,4 transitional adenocarcinoma,3 transitional squamous adenocarcinoma and 2 squamous adenocarcinoma mixed tumor.Most of the patients had irritable bladder symptoms and hematurine.Partial cystectomy was undergone for 3 of 16 cases,total cystectomy for 10 and radical total cystectomy for 3.The main treatment was partial or total cystectomy.The overall survival rates at 1,3 and 5 years post operation were 81.3%,56.3% and 12.5% respectively.Conclusion There were higher malignancy and worse prognosis in bladder mixed tumor.Early diagnosis and therapy might prolong survival.Radical total cystectomy seems to be the best method of treatment.

Objective To evaluate the effect of technical improvement of radical retropubic prostatectomy(RRP) for patients and reduction of complications.Methods 22 patients with clinically prostate cancer(mean age 67 years,stage B 19 cases,stage C 3 cases) underwent radical retropubic prostatectomy.During operation the dorsal vein complex,puboprostatic ligament,puborectalis sling,the neurovascular bundle,external urethral sphincter,reconstruction of the bladder neck were carefully managed.Results All the patients recovered uneventful except 2 deaths,and they survived and were followed up for a mean time of 16 months(range 1～4 years).The mean operative time was 140 minutes(range 90～220minutes) and the mean blood loss was 600mL(range 250～1500mL).16 cases received blood transfusion for 300～1200mL and no ureteral or rectal injury occurred.The urinary catheters were removed 2～3 weeks after operation.2 cases had stress incontinence 3 months later,1 case encountered urethral stricture and became well after urethral dilation,15 cases had satisfactory erectile function after operation and 3 patients had biochemical failure and endured continually chemotherapy during follow-up.Conclusions Accurate maneuver is handled according to correct anatomy can protect the apex of prostate and its surrounding tissue and reconstructing the bladder neck is helpful to reduce complications and achieve better outcome.
