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

The identification of the specific cause in every patient has important clinical implications, because ischemic stroke is an etiologically heterogeneous disease. The Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification can be used to define the etiology of stroke. However, TOAST classification can not be completed timely on admission of patients with acute stroke, which has impacted early guidance of clinical treatment. This article reviews the biological markers of early differential-diagnostic significance of the TOAST classification.

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.

[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 Cardiac HERG potassium channel currents can cause long QT syndrome .The function of the cardiac HERG potassium channel is regulated by tyrosine kinase and phosphatase , and protein tyrosine phosphatase non-receptor type 11 ( PTPN11) negatively regulates the HERG potassium channel .This study aimed to investigate the effect of PTPN 11 on the electrophysio-logical characteristics of the HERG channel . Methods The plasmids of pcDNA3.1-PTPN11-EGFP were constructed by PCR technique and transfected or cotransfected with the pcDNA 3.1-PTPN11-EGFP plasmid into HEK293 cells using Lipofectamine 2000.The patch clamp technique was employed to record the HERG channel currents in the control group ( HEK293 cells transfected with pcDNA3.0-HERG-EGFP), PTPN11 overexpression group (pcDNA3.0-HERG and pcDNA3.1-PTPN6-EGFP cotransfected HEK293 cells), and PTPN11 overexpression with PAO group . Results The pcDNA3.1-PTPN11-EGFP plasmid was successfully constructed .Green fluorescence was observed in the HEK293 cells transfected with pcDNA3.0-HERG-EG-FP or cotransfected with pcDNA3.0-HERG and pcDNA3.1-PTPN11.The maximum densities of pulse and tail currents were significantly decreased in the PTPN11 overexpression group as compared with the control ([31.85 ±5.54] vs [45.92 ±3.18] pApF, P<0.05;[73.82 ±11.31] vs [108.43 ±7.98] pApF, P<0.05) but markedly in-creased in the PTPN11 overexpression with PAO group ([48.08 ±4.32] pApF;[120.06 ±8.02] pApF) (P<0.05).The time con-stant of deactivation was significantly higher in the PTPN 11 overexpression group than in the control ([622.16 ±46.49] vs [440.70 ± 49.49] ms, P<0.05). Conclusion The overexpression of PTPN11 decreases HERG potassium channel currents , which can be re-versed by PAO.This finding provides a theoretical basis for the application of certain regulatory enzymes in the HERG channel as a treat -ment of long QT syndrome .

Objective To evaluate the application of dual-source CT (DSCT) using low-dose technology in diagnosing complex congenital heart diseases. Methods The DSCT data of 31 cases with complex congenital heart diseas-es conifrmed by operation were retrospectively analysed and classiifed into four groups:group A(≤4 months old, n=12); group B (>4 months old~1 year old, n=3);group C (>1 year~6 years old, n=8) and group D (>6 years old, n=8). Results The diagnosis conformation rate of DSCT with surgery were 94.59%. The diagnostic conformation rate of intracardic anormalies using DSCT was 92.86%. And the diagnostic conformation of DSCT in patients with abnormal connection of atrium or ventri-cle to great vessels and the extrocardic anormalies was 95.65%. The average effective dose in each group were 1.16±0.06 mSv, 1.28±0.07 mSv, 1.96±0.54 mSv and 2.77±0.38 mSv, respectively. The ratio of the high quality images was 90.32%. Con-clusions The application of low dose technology in DSCT can clearly display the anomalies, and signiifcantly reduce the radiation dose without losing image quality as well.
