Objective:To explore the value of social support rating scale using in patients with vasovagal syncope (VVS) .Methods:Social support rating scale (SSRS) established by XIAO Shui-yuan was used .A total of 200 VVS patients were collected from inpatients and outpatients and they received social support status investigation ,another 100 normal people were collected from our physical examination center were regarded as control (normal control group) .Results:Compared with normal control group ,there were significant reductions in scores of each item and total score of social support [ (37.22 ± 9.15) scores vs .(33.50 ± 8.64) scores] in VVS group ,P<0.05 or <0.01 ;compared with male patients ,there were significant rise in scores of subjective support [ (17.63 ± 6.72) scores vs . (18.62 ± 7.56) scores] ,utilization of support [ (7.51 ± 2.26) scores vs .(8.92 ± 2.82) scores] and total social sup-port [(34.32 ± 10.61) scores vs .(36.79 ± 7.86) scores] ,and significant reduction in objective support score [(9.28 ± 4.15) scores vs .(8.37 ± 3.49) scores] in female patients , P<0.05 or <0.01;compared with middle-aged and aged group ,there were significant rise in scores of subjective support [ (17.08 ± 6.34) scores vs .(19.51 ± 6.73) scores] and total social support [(33.18 ± 10.74) scores vs .(36.87 ± 8.73) scores] ,and significant reduction in uti-lization of support score [ (8.47 ± 2.60) scores vs .(7.53 ± 1.95) scores] in young group ,P<0.05 or <0.01. Con-clusion:Social support assessment is help to perform individualized diagnosis and therapy for patients with vasovagal syncope ,and help to improve their quality of life .

The total aralosides extracted from Aralia elata (Miq) Seem. were studied in mice ( 50 mg/kg/d for 7 d ) to investigate the pharmacological mechanisms on the molecular level.The results showed that aralosides can obviously stimulate the production of PGE2、PGF2, and cAMP but reduce the cGMP level and nave no effect on histamine release.It is suggested that the changes in the level of cyclic nucleotide might be due to the alternations of PGs, which is now been suspected as the "Second Messenger" . These findings could explain in part the pharmacological activities of aralosides on the molecular level.

Objective To explore the significance of multiple microelectrode guided technique in determining the sensory?motor area of the sub?thalamic nucleus(STN)in deep brain stimulation(DBS)surgeries. Methods A total of 22 electrophysiological recording data of STNs recorded by multiple microelectrode was retrospectively analyzed ,while another 20 electrophysiological recording data of STNs recorded by a single micro?electrode was recruited as the control group. Results A total of 64 microelectrodes were used in 22 STNs guided by multiple electrophysiological recording electrodes. Sensory or motor activated potentials were recorded in 21 sides(95.5%),while regular discharge was recorded in one side. The average length of typical STN activity on the optimal channel of multiple electrophysiological recording electrodes was 5.58±0.53 mm,and the average length of sensory or motor activated potentials was 3.27±1.54 mm. In contrast,the average length of typical STN activity recorded by single microelectrode was 5.02±1.01 mm. However,sensory or motor activated potentials were recorded in 13 sides(65.0%)with the average length of 1.36±0.98 mm. Among the 22 STNs guided by multiple electrophysiological recording electrodes,the final implanted target was consistent with the initially selected anatomic target in 13 sides(coincidence rate,59.1%). In 9 sides,the electrophysiological target was inconsistent with the initially selected anatomic target. Conclusion STN DBS performed with multiple electrophysiological recording electrodes resulted in better outcomes of recording of the average length of typical STN activity or the average length of sensory or motor activated potentials of STN ,final confirmation of STN sensory motor area and determination of the optimal channel of implantation. Application of multiple electrophysiological recording electrodes provides a premise for the precise electrode placement in STN DBS surgeries.

Based on a correct understanding of the related concepts and system of the evaluation of human resources for military medical sciences ( EHRMMS), this thesis established a three-dimension model of EHRMMS that is composed of the evaluation goal, evaluation subject and evaluation object, and analyzed the factors that affect the crucial parameters in the model.We also analyzed the features and regularity of the evaluation model, and tentatively explored the application of the model.

Objective To study the effect of minielctrocholecystectomy(MEC) for gallbladder stone. Methods The clinical data of 4,200 cases(1991-2000) undergoing MEC were analysed restrospectively; the results of different operotors for the MEC were compared. Results All 4,200 cases were cured. Of them, 41 cases(0.98%) had serious complications, including intraoperative bleeding in 4 cases(0.09%), biliary tract injury in 18(0.43%); stress ulcer in 8(0.19%), and residual stones of biliary tract in 11(0.26%). Conclusions MEC has the following advantages: less trauma, short operation time, fast postoperative recovery and lower expense. The different operotors on MEC have distinguish difference in the results. It is important to preven the complications of MEC.
