Objective To develop an alignment technique based on the movement of body gravity center. Methods As join forces in the system of balance is zero, the position of body gravity center can be calculated by body gravity which is taken from weight sensors, by the special software. Meanwhile, the position of body gravity will be sent to control unit, which can be transformed to driving signal of motor. The sliding table with laser, linked to motor, can make pursuit movement following with body gravity. A precise alignment can be made as the movement of body gravity. The balance function test is also used to make an assistant estimate for the alignment. Results and Conclusion An alignment technique has been developed for the fit of prosthesis and orthotics.

Conclusion Through simulative assessment and evaluation as well as probational demonstration,there exits definite scientificality and applicability on this academic assessment and evaluation index system,and it can provide a properly objective evaluation and essential reference foundation in the aspect of introducing more advanced talented personnel in the near future.

Objective To compare the clinical effects of intramedullary nails and locking compression plate in the treatment of femur shaft fracture.Methods The clinical data and follow-up records of 43 patients with femur shaft fracture treated by intramedullary nails and locking compression plate were retrospectively reviewed.Including 31 males and 12 females with an average age of 40.07 years(25 to73).According to AO classification:5 cases were type A,24 cases were type B,14 cases were type C.26 patients in group A treated by intramedullary nails and 17 patients in group B treated by locking compression plate.Operation time,fracture union time,blood loss and complications were compared between the two groups.The Karlstrom and Olerud result were compared and analyzed.Results All patients were followed up at an average of 15 months(range 5-24) after surgery.According to Karlstrom and Olerud score system,the excellent and good rate of group A was 88.4％,higher than the group B 82.3％.But there was no significant difference between the two groups.In group A:the operation time (113.77 ±20.14)min,the blood loss in the operation (386.74 ± 65.16) ml,clinical bone healing (15.52 ± 1.77) weeks.All these outcomes were better than group B (P ＜ 0.01).One case in group A appeared screw loose,but X-ray showed the nail stable,the bone wasn't displacement.One case in group B appeared broken plate 1 month after operation,and received twice operation,the clinical outcome was good as well.Another 1 case with fracture delayed union in group B,after internal fixation removed,we check the X-ray showed bone union.Conclusion Two methods of treatment femur shaft fracture can all reach the above requirement.Fixation of intramedullary interlocking nail is the preferred surgery than locking compression plate.

Objective To investigate the relationship between bile amylase (BA) elevation and biliary tract disease in patients with normal pancreaticobiliary junction (NPBJ). Methods The bile juice was collected from bile duct in 202 consecutive cases who underwent therapeutic endoscopic retragrade cholangiopancreatography (ERCP) for biliary diseases ( biliary bile group), and from gallbladder (GB) in 73 consecutive cases who underwent percutaneous transbepatic cholecystoscopy for extraction of GB stone ( GB bile group). In biliary bile group, in addition to the measurement of BA, the level of lipnse (n =68), bacteria culture ( n = 149 ), manometry of Oddi's sphincter ( n = 27 ) and bile duct ( n = 38) were also performed. In GB bile group, additional GB biopsy was taken in 31 cases. No patient with pancreaticobiliary maljunction, history of cholangiojejunostomy or post-endoscopic sphincterotomy was included in the study. Results In biliary bile group, BA level was elevated in 95 patients (47. 0% ), in which there was no significant difference between neoplastic and non-neoplastic cases ( 56. 9% vs. 43.7%, P > 0. 05 ), although BA was elevated in most patients with hiler cholangiocarcinoma (7/9). The level of BA was correlated with bile lipase (r =0. 561 ), but not with pressure of Oddi's sphincter or bile duct. No significant difference in positive rate of bile bacteria culture was detected between patients with normal BA level and those with elevated level. In GB bile group, BA level was elevated in 25 patients (34. 3% ), in which the frequency of GB epithelium dysplasia is 87.5%, which was significantly higher than that from patients with normal BA level ( P < 0. 001 ). Conclusion The patients with biliary tract disease and NPBJ have high incidence of reflux of pancreatic juice into bile duct. In patients with elevated BA level, there was no significant difference between incidences of neoplastic or non-neoplastic disease, while the frequency of GB epithelium dysplasia and hilar cholangiocarcinoma were higher than those from patients with normal BA level.

BACKGROUND:Tantalum rod implant technology is a new method of early osteonecrosis treatment. Current research on stress distribution before and after tantalum rod implant in different sizes of femoral head necrosis area is few. OBJECTIVE:To analyze the stress distribution before and after tantalum rod implantation in different sizes of necrotic femoral head area using three-dimensional finite element method. METHODS:Three-dimensional finite element models of normal femoral head and necrotic femoral head of 15, 20 and 30 mm diameterwere constructed. Eight measuring points were chosen on two tiers of each necrotic model to detect the stress distribution and its alteration before and after tantalum rod implantation. RESULTS AND CONCLUSION:(1) Stress concentration werefound on every necrotic femoral head, most pronounced on the one with 30 mm lesion. (2) Tantalum implant appeared to reduce the stress concentration generaly. Comparison of the peak points of these models indicated most significant benefit in 15 mm lesion, next in 30 mm lesion, last in 20 mm lesion. (3) Results indicate that larger lesion entails more concentrated stress distribution and more likely to colapse. Tantalum rod implantation can delay the development of necrosis of the femoral head, andismost effective in smal lesion.

Objective To investigate the effect of tramadol combined with sufentanil on postop-erative analgesia in patients received upper-abdominal surgery.Methods One hundred and fifty pa-tients scheduled for selective upper-abdominal operation were randomly divided into five groups (n=30 each):Tramadol group (T);large dose sufentanil combined small dose tramadol group (TS1 );balanced tramadol and sufentani group (TS2 );small dose sufentanil combied large dose tramadol group (TS3);sufentanil group (S).Postoprative VAS scores were recorded respectively at 1,4,8, 12,24,36,48 h when be in quiet and turning 90 degree,Ramsay sedation score,analgesia pump pressing times and side effects were also recorded.Results VAS scores in group TS2,group TS3 and group S at each time point both be in quiet and turning 90 degree were significantly lower than that of group T and group TS1 (P <0.05).Group S sedation score significantly higher than group T (P <0.05).No significant difference in other groups.Conclusion Balanced tramadol and sufentanil group has best analgesic effect and least side effects.With the increasing doses of sufentanil,its analgesic effect was not obvious enhancement.
