The purposes of this study were: (1) to test healthy young adults' ankle plantar and dorsal flexor muscles strength, providing integrate data and scientific basis for sports training, sports injury and recovery. (2) to investigate the biomechanical rule of healthy adults' ankle plantar and dorsal flexor muscles. Methods: 70 college students (35males and 35 females) volunteerily took part in the test. An advanced Cybex-6000 dynamometer was employed. This test consisted of two sections, isokinetic concentric (CON) test and isometric test. Results: males and females adults' ankle dorsal flexor isometric peak torque (PT) increased and plantar flexor isometric PT decreased with the increasing of testing angle. CON PT decreased while the test angle velocities increased. Plantar flexor PT were higher than corresponding dorsal flexor in two tests ( P

Objective To investigate the sedative effects of different fractions of patrinia scabiosaefolia fisch. in mice and provide some valuable information for isolating components with sedative effect.Methods Petroleum, acetic ether and n-butanol fraction was isolated from the patrinia scabiosaefolia fisch.. The sedative effects were determined with locomotor activity assay, hole board test and sodium thiopental-induced sleeping time assay, and it was compared with the effects of total 70% ethanol extract. Results N-butanol fraction showed better sedative effect compared with others, and it was in a dose-dependent manner. Conclusion The results showed that the main active principles of patrinia scabiosaefolia fisch. were the n-butanol fraction, and the promising active chemical might be obtained from this fraction.

[Objective]To apply interal fixation with new pterygo-shape titanium mesh cage in the treatment of degenarative cervical spondylosis.[Method]Twenty-seven patients of degenarative cervical spondylosis were reconstructed after vertecotomy with the cage including 19 cases of CDH,8 cases of OPLL,18 cases in male and 9 cases in female;single segment degenaration were 21 cases,double segment degenaration were 6 cases.All cases were excluded fracture,dislocate by X-ray and MRI preoperatly.[Result]All 27 patients were followed up for an average time of 10 months(from 6 to 14 months).The anverage time of bone graft fusion was 10 weeks.[Conclusion]The pterygo_shape titanium mesh cage can provide immediate biomechanical stability and prevent the mesh cage displace,subsidence,exodus after operation.The surgical procedure is simple,safety and without illic-bone graft,meanwhile can greatly relieve patients' economy burden.Then the internal fixation is elastic fixation,the bone fusion shows a satisfactory result.

Objective To investigate the role of endoscopic color Doppler ultrasonography (ECDUS) in the preoperative localization of insulinomas. Methods Seven patientsd woman) with biochemically diagnosed insulinoma underwent abdominal US, spiral CT and ECDUS in an attempt to precisely localize the tumor before surgery. Surgical and pathological results were considered as the definite localization of tumor. The role of ECDUS in the preoperative localization of insulinomas was compared with that of abdominal US and spiral CT. Results Ten tumors were detected by surgery and pathology. The sensitivity of ECDUS in identifying insulinomas was 8/10 compared with 1/10 for CT and 0/10 for abdominal US. Two tumors not detected by ECDUS had a size below 0. 5cm. Conclusions ECDUS is superior to spiral CT or abdominal US, and should be served as the first choice in the detection of pancreatic isulinomas. ECDUS identification depends on the size of the tumor and 'is hard to detect the tumors smaller than 0. 5cm.

Objective To study the technique and to evaluate the clinical value of stent implantation by butt joint of percutaneous transhepatic biliary drainage (PTBD) and endoscopic retrograde cholangio-pancreatography (ERCP) for the treatment of obstructive jaundice. Methods 24 patients with obstructive jaundice were treated by butt joint of PTBD and ERCP after the ERCP failure, and the clinical results were evaluated. Results A total of 24 cases with obstructive jaundice were successfully operated by butt joint of PTBD and ERCP. In PTBD, 10 cases were punctured from right side, and 14 cases were from left side. PTBD, ERCP and butt joint were done simultaneously in 16 cases, and separately in 8 cases. The total serum bilirubin decreased by 47.07 in 4 days, and the direct bilirubin decreased by 45.43. Infection of biliary tract was the main complication. Conclusion Stent implantation by butt joint of PTBD and ERCP for the treatment of obstructive jaundice may be chosen to treat the patients who failed in ERCP alone.

[Objective]To analyze the MRI and CT characteristics of the pathological changes of ligamentum flavum.[Method]Clinical data of MRI and CT characteristics of 48 cases of lagamentum flavum pathological changes were analyzed and compared retrospectively.[Result]MRI showed"\"signal in sagital position and"V"signal from the vertebral canal in stalk postition.CT showed two sides of soft tissue signal of vertebral canal and some part presented bone substance density.[Conclusion]The MRI,CT images of the ligamentum flavum pathological changes have both advantages and disadvantages.It would benefit the clinical therapy only with the combination of them.

Objective To observe the effect of atropine and N-nitro-L-arginine methyl ester (L-NAME) on the pressure of lower esophageal sphincter (LESP) regulated by electro-acupuncturing (EA) at Zusanli acupoint (He-Sea, st 36) of stomach meridian and explore the neural mechanism of EA. Methods Forty-eight rats were divided into six groups:control group, EA group, atropine group, atropine+EA group, L-NAME group and L-NAME+EA group. LESP was observed and recorded by using three-channel perfusion manometric measurement system. Results LESP increased significantly under or after EA at Zusanli acupoint. Cholinergic M receptor blocker partly abolished the influence of EA on LESP, but EA could restore the decreased pressure of cholinergic M receptor blocked rats. Nitric oxide synthase (NOS) inhibitor increased LESP, and EA could make it higher. Conclusions The main efferent pathway of regulating effect of EA at Zusanli acupoint on LESP is via the chlinergic nerve of vagus, and other mechanism possibly exits.

Objective To investigate the changes of carotid, lipidemia and fibrinogen in type 2 diabetes mellitus patients complicated with cerebral infarction (DCI). Methods 58 cases of DCI (DCI group) were enrolled in this study, and 36 cases of cerebral infarction without diabetes mellitus served as control group.
