AIM: To study effects of Fuyuanbunao Granules (Radix Ginseng Rubra, Fructus Crataegi, Radix Astragali, Herba Epimedii, Radix Salviae Miltiorrhizae, Rhizoma Alismatis, Rhizoma Acori Tatarinowii) on ATPase activities, MDA level in mouse brain, SOD activities in mouse blood and the quotient of brain. METHODS: On the mouse model of Alzheimer' disease toxified with AlCl 3, the effects of Fuyuanbunao Granules on Na + K + ATPase, Mg 2+ ATPase activities and MDA level in mouse brain, SOD activities in mouse blood were evaluated with spectroscopic analysis, and the weight of brain was measured with analytical balance. RESULTS: Compared with Alzheimer'disease model team, Fuyuanbunao Granules enhance the activities of Na +、K + ATPase, Mg 2+ ATPase, decease MDA level in the mouse brain and enhance the activities of SOD in blood. It also increases the weight of brain. CONCLUSION: It indicates that enhancing the activity of ATPase and deceasing peroxide level may be one of the mechanism for Fuyuanbunao Granules to prevent and cure Alzheimer' disease.

BACKGROUND: Continuous passive motion assisted with diathermia will promote the restoration of joint movement of the extremities.OBJECTIVE: To improve joint movement with continuous motion assisted with diathermia after surgical treatment on simple fracture of upper or lower extremity.DESIGN: A randomized controlled trial.SETTING: Huaxi Hospital of Sichuan University.PARTICIPANTS: Eighty-four cases of simple extremity fracture treated in the Orthopedic Department of Huaxi Hospital of Sichuan University from October 2000 to July 2002 were included in this trial. Of them, 16 cases were elbow movement disorder and 68 were knee movement disorder. They were randomly assigned into two groups with 42 cases each.METHODS: The 42 cases in the treatment group were preheated before continuous passive motion while those in the control group just received continuous passive motion. The improvement of joint movement between thetwo groups were assessed and compared according to the joint movement scale.MAIN OUTCOME MEASURES: The joint movement before and after treatment and the indices of joint movement scale in the two groups.RESULTS: All of the eighty-four cases entered the analysis. The joint movement in the treatment group was better than that in the control group [ (101.40 ± 25.76)° vs (86.14 ± 27.66)°, t = 5.25, P ＜ 0.01 ]. The index of joint movement scale in the treatment group was also higher than that of the control group[ (84.32 ± 16.54) vs(64. 89 ± 13.76) ] ( t = 4.24, P ＜ 0.01 ) ].CONCLUSION: Continuous passive motion assisted with diathermia is better than simple continuous passive motion in improving the joint movement and function of elbow and knee.

Results: Through a variety of wireless transmission technology and the intelligent terminal and regional health data center, it can be further mining, analysis and storage for the data information, and provide diagnostic advice. It can effectively alleviate the tension of medical resources. Conclusion:The establishment of remote health monitoring platform can alert doctors and relatives when data is abnormal to win time for rescue. It can effectively manage the disease treatment, prevention and rehabilitation.

To explore the electromagnetic compatibility in the shelter hospital system to adapt it to the future complex electromagnetic environment. The factors for electromagnetic interference were analyzed, and some measures were put forward including separating the interference source from the sensitive device, setting up shielding space, applying grounding measures, eliminating interference signals by filtering and etc. The electromagnetic compatibility in the shelter hospital system was detected through electromagnetic self-compatibility test and electromagnetic environ-mental suitability test for external radio frequency. Simulations and tests proved that the failures and mal-re-sponse due to electromagnetic interference were avoided in the shelter hospital system. The electromagnetic compatibility scheme can meet the requirements of emergency medical facilities for electromagnetic protection in field conditions.

Objective: To observe the clinical effect of Sertraline in treatment of dysthymia. Methods:63 outpatients diagnosed as dysthymia according to ICD-10 were randomly assigned to study group (n=33) and placebo group. Randomized double blind control study was done for 8 weeks with Sertraline from 50-200 mg/d. HAMA and HAMD were used to assess the effect.Results:At the end of 8 weeks, 54 patients completed the trial. Patients of both groups had lower HAMD scores than baseline from 2 weeks, and this trend continued through the 8 weeks observation. During this period, HAMD score of the study group declined more significantly than that of the placebo group. At the end of 8 weeks, the score of HAMA of the study group was also lower than that of the placebo group. The side effects of Sertraline were mild.Conclusion:Sertraline is effective in treatment of psychiatric outpatients with dysthymia.

Objective To explore the puncture technic and method of the transabdominal L5/S1 lumbar diskectomy (TALD). Methods Two cases of cadaver were dissected and L5/S1 intervertebral disks were explored and punctured from different angles in order to probe the proper puncture angle for the needling. The radiographs of the lumbar and sacral vertabral samples of 30 cases were scrutinized and analysed to find the pancture imaging marks of the bones. When performing barium meal examinations, the lumbar and sacral spine of 200 cases were inspected to figure out the opacification of the rate imaging marks. 68 cases TALD were reviewed. Results The most pivotal process of the TALD is the needle puncture should be in parallel direction with lumbosacral interspace and then be pushed into the intervertebral disk. In order to make sure of the puncture point two sticking points should be fixed, on the abdomen and the another at the front edges of L5/S1 intervertebral disks. The five imaging makes of the lumbar, sacral, spine together with the neighboring L5/S1 intervertebral disks are of important help to find the front edges. Conclusion The correct puncture method is very important for performing TALD.

Objective To investigate the role and possible mechanism of ultrasound-targeted microbubble destruction for accelerating neovascularisation in ischemic skeletal muscle. Methods Unilateral hind limb ischaemia was surgically induced in thirty wister rats. On postoperative day 7 , the rats were randomly divided into three groups: ultrasound-targeted microbubble destruction group (group A), ultrasound group (group B), and control group. After the end of the experiment , parafin sections for the skeletal muscle from one rat in each group were made to observe the changes in microstructure. The remaining rats were sacrificed at 24 h and on day 7. VEGF expression, inflammatory factor E-selectin, and monocyte chemotactic factor-1 (MCP-1) were detected in the rats. Results As compared with the other two goups, expressions of VEGF, neovascularization, E-selectin, and MCP-1 in the skeletal muscle were significantly increased in group A. Conclusions Microvascular rupture caused by ultrasound-targeted microbubble destruction can promote angiogenesis by stimulating secretion of endogenous VEGF in skeletal muscle; meanwhile, an increase in expression level of inflammatory factors may be one of the mechanisms.

20/min,PaCO2 12?109 or 0.10.26 patients with sepsis infected by Gram negative bacilli were categorized as G-group,15 infected by Gram positive coccus as G+ group and 15 healthy persons as control group.All the cases were proved to have infection by body fluid examination under microscope or bacterial culture.The level of flagellin was determined by ELISA.The peripheral blood mononuclear cells(PBMC)were isolated by the density gradient centrifugation,and total RNA of PBMCs was extracted by RNA BIOzol extract.The level of TLR5 mRNA in the peripheral blood was detected by semi-quantitative RT-PCR.The statistic significance among groups was examined by Students' t test.Results Plasma flagellin levels were below the detection limit of the ELISA kit in both G+ and control groups,while the mean level of plasma flagellin amounted to 6.636?5.147ng/ml in G-group.TLR5 mRNA expression in G-group was significantly higher than that in G+ and control groups,and no significant difference was found between G+ group and control group.Conclusion Flagellin may be involved in the development of ALI through interacts with TLR5.
