Object To study the effects of WUZI SIWU GUASHITANG (WT) against multi glycosides of Tripterygium wilfordii Hook. f. (GTW) induced genital system toxicity in male rats and its mechanism. Methods Male rats in treatment groups were treated respectively with a 80 days oral administration of large , middle and small doses of WT plus a fixed dose of GTW. The rats as control were treated with GTW alone or saline. Thereafter, the changes in testis organ index, the number of spermatozoa, the rate of movable spermatozoa and the structure of spermatogenic cell epithlium were observed and the serum testosterone level was determined by IRMA. Then the comparison was made between treatment and control groups as to above variables. Results As compared with GTW group, large or middle dose of WT significantly increased the weight of testis, the number of spermatozoa and the rate of movable spermatozoa. Large dose of WT could relieve the damage of GTW to the spermatogenic cell epithelium completely and keep the serum testosterone at normal level. Conclusion The combined use of GTW with WT is very useful in relief of GTW induced adverse reactions of genital system in male rats. The mechanism by which WT exerts the counteractive effects is related to protecting the spermatogenic cell epithelium from being damaged by GTW, and keeping the serum testosterone at normal level.

Optical coherency tomography (OCT) is one of the powerful optical imaging tools that allows cross-sectional tomography of the microstructure in living subjects with high resolution. With the rapid development of OCT and a wide range of preclinical and clinical tumor imaging, it provides profound insights into the complex physiological, cellular and molecular behaviors of tumors. Preclinical OCT has elucidated many inscrutable aspects of tumor biology, while clinical applications of OCT are revolutionizing diagnosis and therapies. As a new noninvasive optical imaging technique, OCT can realize the intraoperative imaging of tumor and provide meaningful image data, which will provide great help for the diagnosis, classification and boundary determination of tumor diseases in the future.

ObjectiveTo observe the relationship between neuronal function score and pathological changes of fluid percussion brain injury in rats and to explore their clinical significances.MethodsThe fluid percussion models of brain injury in rats were established by using the improved device with three kinds impact pressure such as 0.1 MPa,0.2 MPa,0.3 MPa,and vital signs and mortality rate were observed.Behavior changes,brain water content,histological changes were observed by Shapira and Wahld method,dry-wet measure,light microscopy at 1 h,6 h,12 h,24 h,3 d and 7 d after operation respectively.ResultsThe animals accepted impact pressure of 0.1 MPa showed temporary hypopnea with mortality rate of 2.08％,those of 0.2 MPa suffered apnoea of ( 10.88 ±2.69 ) s with mortality rate of 4.17％ and those of 0.3 MPa suffered apnoea of ( 20.60 ± 3.02 ) s with mortality rate of 16.67％.As the impact pressure increased,nervous function score minimumly decreased to (7.17 ±0.75) of 0.1 MPa group,(4.83 ± 0.75 ) of 0.2 MPa group and (2.67 ± 0.52) of 0.3 MPa group respectively,and recovered more slowly.Brain water content maximumly reached to (81.12 ± 0.03 )％,(82.74 ± 1.11 )％ and (83.89± 0.04) ％ at time point of 24 h respectively.The brain injury was involved in the outer layer of cerebral cortex,hippocampal formation and brain stem respectively and histological observation verified above findings.Conclusion Light,moderate and heavy fluid percussion brain injury in rats have more and more low nervous function scores,which have positive relationship with more and more serious pathological changes.

OBJECTIVE:To investigate the neuropotective effect and anticoagulation effect of total Saponins of Radix Liriopes on focal cerebral ischemia in rats.METHODS:Chemical reagent Fecl3 was locally applied on the injured vessels to establish middle cerebral artery thrombosis model,and the effects of total Saponins of Radix Liriopes on rats' behavioral disturbance,brain infarct size,the histopathological changes in brain and the expression rate of nNOS immunoreactive positive neurons were measured,and the bleeding time and coagulation time were also detected with glass tube method and tail transection method.RESULTS:Due to the use of total Saponin of Radix Liriopes(10 and 40mg? kg-1),the brain infarct size was significantly decreased,the behavioral disturbance were improved and the expression rate of the nNOS immunoreactive positive neurons in rats were decreased.At doses of 20 and 60mg? kg-1,total Saponin of Radix Liriopes significantly prolonged the coagulation time and bleeding time.CONCLUSION:Total Saponin of Radix Liriopes has nuroprotective effect on focal cerebral ischemia induced by middle cerebral artery thrombosis and significant anticoagulation effect.

Objective To evaluate the effect of military performance stress on the changes of concentrations in salivary chromogranin A ( CgA) ,β-endorphin (β-EP) and salivary IgA ( sIgA) of submariners.Methods Twenty-nine submarine soldiers were selected, and their saliva samples were collected separately at the end of a long dive trip and nine months after relaxation ashore.In addition,the saliva samples of twenty-eight graduate students were collected as the normal control.The method of ELISA was used to detect the level of salivary CgA,β-EP and sIgA.Results After long-term dive training, the submariners showed significantly decreased CgA,β-EP and sIgA.Conclusion After a long term dive trip, chronic military performance stress is associated with the decline of salivary CgA,β-EP and sIgA, indicating that the function of sympathet-ic adrenal medulla is suppressed.The biological significance of these changes needs to be assessed in the future.

Objective To investigate the significance of salivary cortisol , dehydroepiandrosterone sulfate (DHEA-S) and cortisol/DHEA-S ratio changes for evaluation of military performance stress .Methods Forty submarine soldiers were selected, whose saliva samples were collected separately at the end of long-term dive training and after nine months of relaxation break.In addition, the saliva samples of thirty-four graduate students were collected the moment they finished a three-hour final examination and one week later .The method of ELISA was used to detect the levels of salivary cortisol and DHEA-S and to count their ratio .Results After long-term dive training , the submarine soldiers showed significantly decreased DHEA-S and an increased cortisol/DHEA-S ratio, but the cortisol level did not change very much .In contrast, the final examination stress did not change the level of cortisol , DHEA-S or the cortisol/DHEA-S ratio among these students.Conclusion This is the first study to show that long-term, chronic military performance stress is associated with the salivary DHEA-S and cortisol/DHEA-S ratio changes .The increase in the cortisol/DHEA-S ratio may be used as an important and useful biomarker to evaluate chronic stress .In addition , it is relatively simple and sensitive to detect stress biomarkers by using saliva samples .
