[Objective]To explore the surgical plan of lumbar degenerative de novo scoliosis combined with vertebral stenosis(LDDS) and evaluate the surgical efficiency.[Method]From July 2003 to Jan.2007,32 LDDS patients were diagnosed and operated in the author’s hospital.The X-ray,computed tomography and MRI radiological data were measured carefully preoperately which included the Cobb’s angle,vertebral rotational and lateral subluxation degree.All the patients were treated by posterior decompression and pedicle screw internal fixation,and the surgery,fluoroscopic time and bleeding amount were recorded.Patients were administered pre- and postoperatively with clinical outcome surveys of Visual Analogue Pain Score(VAS),Low Back Outcome Score(LBOS).Pre- and postoperative measurements of the Cobb's angle and lumbar lordosis of the involved segments were analyzed.[Result]The surgery time was 4?0.5 hours,the average bleeding amount was 400?30 ml,the fluoroscopic time was 30?5 min.All the patients were followed from 8 months to 4 years,and radiography was proceeded on 8 and 16 months respectively post surgery.Twenty-four cases got good bone fusion,and mean Cobb's angle decreased from 37.2 to 18.4 degrees,mean focal lordosis increased from 13.1 to 16.4 degrees,mean vertebral rotation angle decreased from 14.2 to 9.8 degrees,mean preoperative measures of VAS and LBOS improved from 5.3?2.2 and 24.8?15.6,respectively to 2.2?2.1 and 44.8?18.0 at last follow-up,the Cobb’s angle,lumbar lordosis and the degree of vertebral rotation had significantly difference pre and post surgery(t test,P

Objective To observe effect of ganciclovir on the treatment of the young child viral encephalitis. Methods 68 cases of viral encephalitis were randomly divided into treatment group(45 cases) and the control group (23 cases), the two groups of children with clinical manifestations and treatment effects were observed. Results Headache, vomiting, convulsions symptoms and the resumption of the time was obviously shorter in treatment group than that of the control group, fever symptoms persisted despite the shortened time, but the difference was not statis- tically significant. Conclusion Ganciclovir in children with viral encephalitis have significant effect.

Objective To explore the effect of Schisandrae Sphenantherae on proliferation and differentiation of rat osteoblast in vitro. Methods Using the method of serum pharmacology, osteoblast was isolated from calvaria of newborn SD rats by means of modified sequential collagenase digestion and incubated in RPMI 1640 medium. The cell morphology was observed under a phase contrast inverted microscope. MTT assay, ALP activity, mineral node count were detected to determine the status and activities of proliferation and differentiation. Results In 10%, 15% concentration groups after cultured 48 h and 5%, 10% after cultured 72 h, 75% ethanol extracts of Schisandrae Sphenantherae significantly stimulated the proliferation (P

Objective To evaluate the endoscopic tendon sheath release for stenosing tenovaginitis (trigger finger). Methods Five patients with stenosing tenovaginitis (2 in thumbs, 1 in middle finger, and 2 in ring fingers) underwent operations by Smith & Nephew Endoscopic Trigger Finger Release system. After two 3.0mm transverse incisions were made, the window cannula assembly was inserted subcutaneously along the sheath from the proximal portal and advanced until it passed through the distal portal. Then a 2.7 mm endoscope was passed into from the proximal portal and a retrograde knife was introduced into the operative site from the distal portal. Finally the entire length of sheath was sectioned under direct endoscopic vision. Results All operations were successfully completed. Finger's flexion and extension function recovered immediately after the operations. All the patients restarted their employment one week postoperatively. There were no complications such as distinct pain or delayed wound healing in these patients. Conclusions This method has the advantages of minimal invasion, safety, effectiveness and quick recovery, especially suited to diabetic patients or multiple trigger fingers.

Objective To investigate the necessity of releasing the distal holdfast fibers of the flexor retinaculum(DHFFR) during endoscopic carpal tunnel release(ECTR).Methods The Experiment Group included 16 cases.The operation was conducted under brachial plexus anesthesia without the use of tourniquet.A 1 cm skin incision was made.The USE system(Universal Subcutaneous Endoscope System) was employed.Both flexor retinaculum(FR) and distal holdfast fibers of the flexor retinaculum were cut off.Postoperative outcomes were compared with another 16 cases of flexor retinaculum release only(Control Group).Results Follow-up evaluation was carried out at 6 postoperative months.According to the Kelly's criteria,there were 13 cases of excellent results and 3 cases of good results in the Experiment Group,and 8 cases of excellent,5 cases of good,and 3 cases of fair results in the Control Group.Significant difference was obser red in flameda Ⅱ or Ⅲ grade patients between the two groups in carative effects(?~2=6.278,P=0.043).No serious complications or postoperative recurrence occurred.Conclusions Flexor retinaculum is not the only structure existing in the carpal canal to be released.More attention should be paid to complete decompression of both flexor retinaculum and distal holdfast fibers of the flexor retinaculum,especially in those who have serious symptoms.

0.05). The length and the angle of the proximal tibial slope were (2.34?0.2) cm and (20.1?4.3)?, respectively. Conclusion The specification of entry point of intramedullary nailing must be individual because the shape of proximal tibia varies in different persons.

Objective To look for suitable short-term weight loss and long-term maintenance method for army cadres. Method A total of 142 patients with simple overweight and obesity were randomly selected as the research subjects, and were followed up for 2 years, 130 of them were valid for analysis, 97 were male, and 33 female, age 27-59 years, average(47.41±7.55)years. SPSS 16.0 was used for analysis. Repeated measurements analysis of variance was used for data analysis, K-related samples nonparametric test was used for enumeration data. Result The army cadres population weight intervention management model was divided into three stages. They were respectively intensified weight loss stage for 6 months, the consolidation of weight loss for 6 months, and self-management stage maintained for 12 months, totally 24 months. Variance analysis results showed that after two years of focused intervention and health management, the body mass index(BMI)fell from(27.42 ± 2.81)kg/m2 to(24.69 ± 2.63)kg/m2 (F=2 649.945, P<0.05), waist circumference decreased from(91.09±8.24)cm to(85.26±7.76)cm(F=1 207.248, P<0.05). Nonparametric test results showed that after two years intervention management the behavior patterns concerning physical exercise became better. Exercisers increased from 33.8%to 73.3%(H=68.448, P<0.05); proportion of smoking decreased from 38.5% to 20.0%(H=33.692, P<0.05); drinking alcohol decreased from 50.8%to 20.8%(H=59.128, P<0.05);high salt diet decreased from 39.2%to 23.1%(H=31.722, P<0.05);high-fat diet decreased from 46.2%to 27.7%(H=41.571, P<0.05). Conclusion The practice showed that the short-term intensified weight loss, long-term maintenance, exercise and psychological intervention, changed the cadres population from passive to active on the weight control and self-management with remarkable effects, therefore such intervention is worthy of promoting.

Case based learning/problem-based learning ( CBL/PBL ) is a new teaching method based on traditional medical education methods.In order to conquer the deficiency of traditional education methods in autonomous study motivation and ability of knowledge integration, CBL/PBL has been introduced into vascular surgery teaching procedure since 2006.The quality and effort of CBL/PBL compared with lecture-based learning ( LBL ) were evaluated and scored. The outcome of this teaching innovation shows CBL can arouse students' desire in autonomous study and enhance their ability in clinical analysis.But, its superiority is difficult to develop in the current medical education system.
