Objectlve To study the significance of injury and posthumous changes to the axonal in brain stem and provide evidence to the forensic discrimination of brainstem injury. Methods Select the cases that died of the primary brainstem injury or other disease randomly, All cases were divided into control group and experimental group, control group and experimental group that were autopsied at the postmortem interval less than 24h or 48h, or longer than 24h or 48h. The brainstem tissue were cut and stained by silver; Two hundred four samples were observed in microscope and selected 9～10 widest axonal to measure its diameter, then analysis the data. Results There is significant difference in axonal diameter of midbrain and mudella between control group (not including those cases died of cardiovascular diseases) and experiment group (P0.05). Conclusion The axonal swelling of the brainstem is closely related with the traumatic injury, so axonal swelling is a finding useful for identification of traumatic brainstem lesions, but death from cardiovascular diseases should be excluded.

OBJECTIVE:To probe into the mechanism of Shenqi decoction on inhibiting apoptpsis of myocardial cell in?duced by ischemic reperfusion.METHODS:The mice were randomly divided into Shenqi decoction group(high,middle and low dosage groups),isosorbide dinitrate control group,blank control group and model group.The Shenqi decoction group and isosorbide dinitrate group were respectively administered with drugs by lavage for5days while the blank control group and model group were respectively administered with normal sodium by lavage for5days.Except the blank control group the is?chemic reperfusion model of each group was made,then the activity of superoxide dismutase(SOD),the level of malondi?aldehyde(MDA)of cardiac muscle tissues were determined;the apoptotic index of myocardial cells and the expression of apoptosis-correlated protein Bcl-2and Bax were analyzed.RESULTS:Compared with the model group,the SOD activity and Bcl-2express index have been increased,but MDA level and bax express index have been decreased in Shenqi decoction group.CONCLUSION:Shenqi decoction does have a good protection effect on myocardial ischemia and myocardial cell injury induced by postischemia reperfusion.

BACKGROUND: The blood oxygen saturation is an important physiological parameter of human hfe; it can be affected by multiple factors due to the imbalance of oxygen supply and consumption, and consequently, the normal physical metabolism is affected. The existing manufacturing techniques are complex and are used with higher demands. OBJECTIVE: To investigate the accuracy of the novel reflecting oximeter designed on the basis of reflecting principle in monitoring the variance of blood oxygen saturation with the change of its concentration. DESIGN: To introduce the structure, working principle and design of the reflecting oximeter and make comparative study with adult rabbits as the subjects. SETTING: Cardiopolmonary Bypass Department of Cardiovascular disease hospital of the Chinese Academy of MedicalSciences. MATERIALS: The study was performed at the Departments of Anesthesiology and Cardiopulmonary Bypass of the Cardiovascular Disease Hospital,Chinese Academy of Medical Sciences from August to October in 2001.Ten adult rabbits were selected. METHODS: The oximeter consists of a converter, a driver, a central processing mould and liquid-crystal monitor. It is characterized by the onethree optical cable connected with reflecting probe, postcentral management system and digital displayer. This oxmeter was developed basing on the basis of fixed relationship between blood oxygen saturation and radiant absorbency (or reflecting). In this study,cardiovascular-pulmonary bypass was established on rabbits that were then exposed to oxygen and NO mixture supply of different concentrations,and then the corresponding blood oxygen saturations were determined with the new oximeter and compared with series-wound Baite saturation meter and blood-gas analysis. MAIN OUTCOME MEASURES: The blood oxygen saturation at different concentrations determined with the reflecting oximeter and Baite saturation meter. RESULTS: At the same oxygen concentration, the blood oxygen saturation determined with the new measure was not significantly different from that determined with Baite blood oxygen saturation meter(P＞0.05 ). CONCLUSION: The variance of blood oxygen saturation with the change of oxygen concentration can be detected by the reflecting oximeter with the result similar to that by Baite blood oxygen saturation meter.

Objective To explore the correlation between the strength of trunk flexors and extensors obtained by isometric and isokinetic concentric tests. Methods The strength of trunk extensors and flexors were measured by isometric and isokinetic concentric tests during trunk flexion and extension in 50 healthy subjects, and the peak torque of flexion and extension (FPT and EPT) and the ratios of FPT/EPT were analyzed with correlation and regression analysis. Results The FPT and EPT of trunk flexors and extensors were positively correlated (r_F=0.827,P0.05, respectively), the regression equations of FPT and EPT were y^=8.158+1.097X and y^=-12.375+0.781X, respectively. Conclusion The isometric test of the trunk extensors and flexors could assess accurately the changes of the trunk muscle strength without aggravating pain and diseases. It is more reasonable to evaluate the stability of trunk with the FPT/EPT ratio at neutral position.

OBJECTIVE: To study the pharmacological activities and toxicity of the crude alkaloids of Toddalia asiatica and to provide pharmacological data for the further development of this herbal medicine. METHODS: We observed the anti-inflammatory effects of the crude alkaloids of Toddalia asiatica, using xylol and agra to induce the turgidness and sodium carboxymethyl cellulose (CMC-Na) to induce leucocyte strolling in the rats. The analgesic effects were observed by body-distortion methods. The effects of alkaloids of Toddalia asiatica on hepatic function were observed by testing the contents of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum and calculating the liver index. The LD 50 and 95% creditability were calculated with developed Karber Method. RESULTS: The administration of alkaloids of Toddalia asiatica had the function of inhibiting the auricle swelling caused by xylol and joint swelling caused by agar and leucocyte migration caused by CMC-Na, decreasing the body-distortion of the rats. After two weeks administration, the contents of ALT and AST showed that there was no obvious difference between administered group and control group. The LD50 of the crude alkaloids of Toddalia asiatica was 1.622 g/kg and the 95% creditability was 1.29-2.03 g/kg. CONCLUSION: Toddalia asiatica has anti-inflammatory and analgesic effects, and there is no injury to the liver after long-term administration in rats.
