Objective: To explore the possible factors that affect the mental health of military officers and soldiers in Tibet and provide the basis for the prevention of mental disorder and the practice of mental intervention. Methods: 90 Symptoms Check List (SCL-90),Life Events Scale(LES) and self-made questionnaire for general condition were used to investigate 299 army officers and soldiers who stationed in the frontier post of Tibet. The subjects were chosen in the principle of cluster sampling in squad or platoon. Results: The factors of environment satisfaction, negative live events, ways of entering Tibet, total score of life events, army years and age were positively related with SCL-90, while the hometown living condition had significantly negative relation with SCL-90. The factors of environment satisfaction, negative life events ,army years, motivation of joining the army, ways of entering Tibet and hometown living condition were in the regression equation(P

Objective To report the modified surgical technique currently used for the construction of an orthotopic ileal neobladder.So as to improve the vesical function of urinary storage and urination after total cystectomy. Methods Radical cystectomy and ileal neobladder with double “U” shape were performed in 20 patients with transitional cell carcinoma. After the detubularized ileal segment approximately 40 cm in length was arranged in a U configuration,the two medial borders of the U-shaped open segment were oversewn with a single layer seromuscular continuous 2-0 polyglycolic acid suture.The bottom of the U was folded over between the two ends of the U.Thus a spherical pouch, the neobladder, was fashioned. During that period, the neobladder anastomosed to the urethra.The ureters were implanted according to the improved stitching method. Results The operative time to form a neobladder was (90?15)min.Follow-up turned out that no perioperative or early postoperative mortality was observed, and no severe early complications occurred. The mean postoperative follow-up time was 25 (range,6 to 48) months.All the 20 cases achieved excellent continence except for 6 cases with temporary incontinence at night.Dysuria occurred in 1 case,and hydronephrosis on the left was found in 1 case.Six months later, the mean bladder capacity was 340 ml (range,250 to 450 ml). Conclusions The construction of an ileal neobladder using a smaller part of ileum that has been completely detubularized and fashioned by double U shape is easy and agreeable to perform.This mode of operation has low complication rates, achieves adequate capacity at low pressure, and provides satisfactory continence rates.

Objective To explore the selection of reasonable interventional treatment to portal hypertension under different conditions.Methods The data of 76 patients with portal hypertension and interventional treatment from 1997 to 2002 were retrospectively analyzed. 26 patients were treated with transjugular intrahepatic porto-systemic stent shunt (TIPSS). Of these 26 patients, 11 patients suffered from hemorrhage after surgery treatment by devascularization, 6 patients with hemorrhage after stomach mirror treatment, and 9 patients with ineffective medicine treatment. 50 patients were treated with percutaneous transhepatic variceal embolization (PTVE) combined with partial splenic embolization (PSE), and they all showed inefficacy by medicine treatment. Free portal pressure (FPP) in pre- and post-treatment was measured in all 76 cases. The hepatic volume was measured by spiral-CT before and one year after the treatment.Results In TIPSS group, FPP was reduced from (3.85?0.42) kPa to (3.09?0.44) kPa (( t= 3.682, P

OBJECTIVE: To establish the quality standard of Yishen granules.METHODS:Polygonum multiflorum,Ganoderma,Radix Astragali and Angelica sinensis in the formulation were identified by TLC.The content of stilbene glucoside in polygonum multiflorum was determined by HPLC.RESULTS: The TLC identification method exhibited good specificities.The samples were similar to the references /control in that their TLC spots assumed identical color at the corresponding places,yet without the interference form the negative samples.The linear range of stilbene glucoside was 0.037 75～0.755 ?g(r=0.999 5) and the average recovery was 99.44%(RSD=1.79%,n=6).CONCLUSION: The established standard is accurate,reliable and applicable for the quality control of Yishen granules.

[Objective]To analyze the therapeutic effects of percutaneous kyphoplasty for acute versus chronic osteoporotic vertebral compressive fracture.[Method]Percutaneous kyphoplasty was performed in 56 patients(137 vertebraes) with osteoporotic vertebral compression fracture (VCF).Based on the changes on MRI,all compression fractures were divided into 3 types:acute VCF,repairing VCF and chronic VCF.Types were examined for differences in treatment efficacy,according to the anterior/middle vertebral body height,Cobb's angle and visual analogue scale(VAS) at pre-and post-operation.[Result]All patients with the VCFs had rapid and significant improvement in back pain following percutaneous kyphoplasty.VAS was from 8.09?1.12 preoperatively to 2.31?0.91 postoperatively,and 2.26?0.88 at final follow-up.The results showed that 41 cases were Type Ⅰ on MRI,69 were Type Ⅱ and 27 were Type Ⅲ.Significant improvement was observed at the post-operative versus pre-operative assessments in Type Ⅰ and Type Ⅱ.No significant differences were observed between post-and pre-operative assessments in Type Ⅲ.[Conclusion]The curative effect of percutaneous kyphoplasty for the treatment of acute VCFs appears superior to that of chronic VCFs.After a definite diagnosis of VCFs,percutaneous kyphoplasty should be performed as early as possible in order to obtain a better therapeutic effect.

[Objective]To observe the correlation between electromyogram(EMG) combined with MRI and clinical outcome in patients with cervical spondylotic myelopathy(CSM). [Methods]Patients with CSM who were confirmed by clinical and image examination were examined by EMG.Peripheral nerve injury such as cubital tunnel syndrome and carp tunnelsyndrome were excluded.Eighty-nine cases were selected and followed-up after surgical treatment with anterior,posterior,or posterior-anterior combined surgery.Four types were classified according to EMG and MRI.Type I:EMG/MRI(-/-).Type II:EMG/MRI(-/+).Type III: EMG/MRI(+/-).Type IV:EMG/MRI(+/+).The clinical outcome were also graded according to the Japanese Orthopaedic Association(JOA) scoring system.Furthermore,the data were analyzed statistically to explore the correlation of the factors.[Results]The results showed that 36 cases were in Type Ⅰ,17 were in Type Ⅱ,10 were in Type Ⅲ and 26 were in Type Ⅳ.Clinical function was excellent in 42 patients,good in 20 patients,fair in 18 patients,and poor in 9 patients.There was a good correlation between types and the clinical outcome(Hc=30.72,P

Objective To investigate the treatment effect of gamma knife radiosurgery for hypothalamic hamartomas. Methods Gamma knife radiosurgery was performed in 9 patients with gelastic seizures. Collimator helmets (4 and 8 mm) were used and a radiosurgery plan was designed to cover 90% of the hamartoma at the 40%~55% isodose curve with the center dose of 28~40 Gy and the margin dose of 12~18 Gy. The clinical outcome was evaluated with the Tan’s scale. Results No complications due to gamma knife radiosurgery occurred. A follow-up from 24 to 54 months showed effectiveness in 7 patients, disappearance of seizure in 1 patient, rare occurrence in 3 patients, significantly reduced occurrence in 2 patients, improvement in seizure control in 1 patient, but ineffectiveness in 2 patients. Conclusion As an approach to the treatment of hypothalamic hamartomas, gamma knife is a safe and cost-effective therapy with rare side effects for hypothalamic harmatomas.

Uterine papillary serous carcinoma is a special pathological type of endometrial cancer. It is similar to ovarian papillary serous carcinoma in histology and can have distant metastasis when it is still confined to the endometrium. As it is very aggressive and has a rather poor prognosis,complete surgical staging is necessary in the treatment,assisted by radiotherapy and chemotherapy. In this review,the author discussed the recent research advances in uterine papillary serous carcinoma.

The latest reports showed that kidney secrets a new type protein:renalase,a novel flavin adenine dinucleotide-dependent(FAD-dependent)amine oxidase which is secreted into the blood by the kidney and regulates heart function and blood pressure by metabolizing catecholamines.Kidney disease is associated with cardiovascular disease,so people pay more and more attentions to renalase.This article will introduce the structure and mechanism of renalase,and propose its future.
