The relationship between soluble cytotoxic T lymphocyte associated antigen-4 (sCTLA-4) and imbalance of Th 1/Th 2 cytokines was investigated in patients with Graves′ disease. The results showed that sCTLA-4 was increased, IL-4 decreased. IFN-? did not significantly change, IFN-?/IL-4 was raised and there was a negative linear correlation between sCTLA-4 and IL-4, suggesting that imbalance of serum Th 1/Th 2 cytokines with a decline in Th 2 cytokine was associated with increased sCTLA-4.

ObjectiveTo observe the protective effect of tetrahydroxystilbene glucoside (TSG) on rats' hippocampal neuronal damage induced by glutamate (Glu) in the culture.MethodsHippocampus was isolated from newborn SD rats and dispersedly cultured in the medium for 9 days. Neurons were incubated with TSG (5—100μmol/L) for 24h, the cells were washed twice with Lock's solution without Mg2+,then Glu 500 μmol/L was added. Thirty min later, the reaction was terminated by washing the monolayer cells twice with the Lock's solution and then cultures were kept at 37℃ for 24h. Cell viability was measured by MTT method and cell membrane damage was determined by LDH leakage; with Fluo-3/AM as an intracellular calcium indicator and added into the bathing medium, fluorescent intensity of intracellular free calcium were observed through laser scanning confocal microscopy (LSCM).ResultsAfter the treatment with 5—100μmol/L TSG for 24h, the decrease of cell viability and the increase of LDH leakage caused by Glu was obviously resisted dose dependently. TSG inhibited increase of Ca2+ in cytoplasm, compared with model group.ConclusionTSG can significantly promote the cell viability and reduce the cell membrane damage in Glu treating hippocampal neurons. The neuroprotective activities of TGS is mediated by inhibiting Ca2+ overload in cytoplasm.

OBJECTIVE:To investigate the protective effects of diphenyl ethylene glycoside(TSG)on hippocampal neuron cells ischemic injury model rats.METHODS:Hippocampal nerve cells ischemic injury rats’model was established with sodium dithionite,antagonism of TSG on ischemic cerebral injury was determined by methyl thiazolyl tetrazolium(MTT)microcol-orimetry and lactate dehydrogenase(LDH)efflux assay.RESULTS:Pseudo-ischemic cerebral injury could cause significant injury to neurons with elevated cell death rate,significantly decreased MTT value and increased LDH efflux rate.The appli-cation of TSG could lead in significantly decreased LDH efflux rate,elevated MTT value and reduced cell death rate.CON-CLUSION:TSG has a significant protective effect on nerve cells ischemic injury model rats.

Academe hash't got the same view about science attribute of traditional Chinese medicine(TCM)up to now.This article demonstrates the scientific attribute of the traditional Chinese medicine from the nature of science,the seientific attribute of medical science and the relationship between the traditional Chinese medicine and medical science.TCM needs development.In order to develop the traditional Chinese medicine quickly,on the basis of inheriting tradition,we should make the best use of modem scientific technology.Not simply copy the theories and methods of western medicine but using the scientific measurement to build up the measurement of TCM symptoms,the relationship between symptoms and the change of the body,explore the process of physiology and pathology,and combine with western medicine to develop a mature science-medical science.

Objective To investigate the causes,diagnostic methods,prevention and cure of postmenopausal bleeding(PMB).Methods The clinical and pathological data of 210 PMB patients admitted in this hospital were retrospectively analyzed.Results The causes for PMB were benign diseases(69.5%),the most of which were infec- tious diseases(49.5%),non-organic disease(20.5%)and malignant tumor(10.0%).Compared with benign diseases and non-organic diseases,the attack age of malignant tumor was higher[(67.1?6.9)years old],menopausal dura- tion was longer(11.6?2.9)years,bleeding duration was longer[(157.6?26.4)days],and mucous membrane was obviously thickened[(14.6?3.2)mm](P0.05).Conclusion The main cause for PMB is benign diseases,followed by non-organic diseases.More attentions should be paid to the PMB patients with higher attack age,longer menopausal duration and bleeding dura- tion,and obviously thickened mucous membrane,so as to be precautions to the occurrence of malignant tumor.

Object To investigate the effects of Congsheng Capsule (CSC) on free radical change after cerebral ischemia reperfusion, and analyze the mechanisms of CSC anti cerebral ischemia action. Methods Bilateral carotid artery occlusion and reperfusion combined with tail bleeding hypotension were employed in this study. Changes in free radicals were observed by means of spectro photometry. Results CSC 1, 3, 9 g/kg could enhance SOD activity, reduce the MDA content, and decrease NOS activity and NO content. Conclusion The protective effects of CSC on cerebral ischemia may be mediated by its anti free radical and NO damage.

Object To investigate the profective effects of Congsheng Capsule (CSC) on cultured cerebral cortical neurons after cerebral ischemia reperfusion in order to study the anticerebral ischemia effect of CSC. Methods Drug containing serum was used to study the protective effect of CSC on neurons damaged during hypo glucos and hypoxia (3 h)/reoxygenation (0, 3, 6, 18 h), the demage to neurons was reflected by the increase in activity of lactate dehydrogenase (LDH) released from cells into culture medium and the changes of apoptosic cells which were studied by flow cytometry. Results The serum preparation of CSC (2, 4, 8 g/kg) attenuated neuronal damage during hypo glucos and hypoxia (3 h)/reoxygenation (0, 3, 6, 18 h) by decreased LDH and changes in apoptosic cell numbers. Conclusion CSC has protective effects on cerebral ischemic damage.

The realization of symptom measurement of the traditional Chinese medicine is a must for the development of traditional Chinese medicine, which obtained a common acceptation academically. This article believed the methods for realizing symptom measurement are the combination of both TCM two basic theories of "the wholism conception" and "treatment based on syndrome differentiation" and modern scientific measures and methods. Meanwhile, the western medicine should be simply excluded, other than simply compare a TCM syndrome to a physiological and biochemical indicator of western medicine.
