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.

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.

Obiective To discuss the diagnosis value, limitations and mutual complement of MRI and TDUI in the fetus. Methods, TDUI and MRI was performed in 24 cases pregnant women that suspected fetus congenital malformation by Ultrasound examination, the examination results were compared by MR1 and TDUI with the clinical results.Results The 9 cases congenital malformation of 24 cases pregnant women were found by MRI. The 9 cases were confirmed and 3 cases were more sufficient by MRI. The one case examined by MRI was normal other than Ultrasound examination. Conclusion MRI is superior to Ultrasound in diagnosing malformation of nervous system. The Ultrasound and the TDUI in particular is better in finding the surface malformation than MRI. In clinical application, MRI and Ultrasound must be connected to make up the limitation and have a definite diagnosis.

Objective:To study the CT and PET/CT features of pleural mesothelioma and the value of CT and PET/CT imaging in the diagnosis of the disease.Methods:We retrospectively analyzed the spiral CT images of 23 patients and PET/CT images of 7 patients with pleural mesothelioma,all histologically confirmed.Results:Of the 23 cases detected by spiral CT,7 were benign and 16 malignant;local nodular pleural thickening was found in 9 cases,7 benign and 2 malignant;diffuse pleural thickening was observed in 14 cases,all malignant.Of the 7 cases diagnosed by PET/CT,5 were excluded from surgery.Conclusion:CT imaging helps determine the location,shape,extent of the pleural lesion and its relation to the surrounding tissues,while PET/CT is better in the differentiation of pleural mesothelioma and staging of malignancy,and therefore plays an important guiding role in the treatment of the disease.

Objective: To discuss the imaging features of esophageal fistula and the value of intervention.Methods: We retrospectively analyzed the complete clinical data of 12 cases of esophageal fistula treated from June 2000 to May 2008,of whom,2 developed esophago-thoracis fistula and esophago-mediastinum fistula respectively after conservative radiotherapy,and 10 developed esophageal fistula after surgery for esophageal cancer.All the patients received iodine-based oral contrast,spiral CT scanning and intraperitoneal stent implantation for fistula closure.Results: Iodine-based oral contrast showed that the contrast agent overflowed into the chest in 8 cases,into the airway in 3 and into the mediastinum in 1.Spiral CT scanning revealed 8 cases of pleural fistula and 2 cases of remnant stomach-airway fistula,but failed to display the other 2 because of the small size.Intraperitoneal stent implantation was successfully accomplished in all the cases,which helped to close the fistula,take in food,stop bucking,control lung,mediastinum and other infections,and improve the patients' quality of life.Conclusion: Esophageal fistula can be effectively diagnosed based on the findings of iodine-based oral contrast and spiral CT scanning.As a novel technique,intraperitoneal stent implantation for fistula closure,simple,safe and with obvious immediate effect,is well worth promoting.
