Objective To investigate the relationship between the expression of decay receptor 3 (DcR3) and the eliniealpathological parameters in human gastric carcinoma. Methods The expression of DcR3 was examined by RT-PCR in a series of 41 human primary gastric carcinomas and 41cases of normal tissue adjacent to tumor. Multiple clinical pathological factors were analyzed according to their relation with the expression of DcR3. Results The positive rate of expression of DcR3 was 56 %(23/41) in human gastric carcinoma. The expression of DcR3 in gastric carcinoma was significantly higher than that in normal tissues adjacent tumor. The expression of DcR3 was significantly correlated with different degrees of differentiation, lymph node metastasis and TNM staging (P <0.10), but there was no significant difference in DcR3 and other clinical pathological features such as tumor position and invasion depth (P>0.10). The multiple linear regression equation was Y=0.432-0.208X1+0.098X2+0,086X3. Conclusion DcR3 expression can be highly found in gastric carcinoma. The abnormal expression of DcR3 may promote tumorigenesis and progression. DcR3 may be important in evaluating the tumor differentiation, infiltration depth, lymph node metastasis and TNM staging of human gastric carcinoma.

OBJECTIVETo study the significance of plasma D-dimer and von Willebrand factor (vWF) and the therapeutic effect of compound glycyrrhizin in children with cytomegalovirus (CMV) hepatitis.
METHODSTwenty healthy children, 16 asymptomatic cases with CMV infection and 52 cases of CMV hepatitis (21 cholestatic and 31 non-cholestatic) were enrolled. The 52 children with CMV hepatitis were randomly administered with conventional treatment alone or conventional treatment plus compound glycyrrhizin treatment. Plasma D-dimer and vWF levels were measured before and after treatment.
RESULTSPlasma D-dimer and vWF levels in the CMV hepatitis group were markedly higher than those in the healthy control and asymptomatic CMV infection groups (P<0.01). The cholestatic hepatitis group had more increased plasma D-dimer and vWF levels compared with the non-cholestatic hepatitis group (P<0.01). Plasma D-dimer and vWF levels in the CMV hepatitis group were markedly reduced after conventional or compound glycyrrhizin treatment (P<0.01). Compound glycyrrhizin treatment decreased more significantly plasma D-dimer and vWF levels compared with the conventional treatment in children with CMV hepatitis (P<0.01).
CONCLUSIONSThe detection of plasma D-dimer and vWF is useful in the early assessment of liver damage in children with CMV hepatitis. Compound glycyrrhizin can decrease obviously plasma D-dimer and vWF levels and might thus provide protective effects against liver damage.

AIMTo compare the antagonistic effects of 6 beta-naltrexol and naltrexone against morphine analgesia.
METHODSThe effects of 6 beta-naltrexol and naltrexone against morphine analgesia were observed in mouse heat radiant tail-flick assay and in mouse (55 +/- 1) degrees C hot plate test. The displacement of 6 beta-naltrexol and naltrexone on binding to CHO-mu receptor was observed by radioligand binding study.
RESULTS6 beta-naltrexol antagonized morphine analgesia but the potency was (6.1 +/- 1.7)% that of naltrexone. The effective duration of 6 beta-naltrexol was 3-4 times that of naltrexone and the peak time of the response was about 0.5-1 h after s.c. equivalent efficacy dose (ED95) in two models. Like naltrexone, 6 beta-naltrexol was effective by oral administration and the potency ratio of p.o./s.c. was 1/3. As an antagonist to opioid receptor, the displacement of 6 beta-naltrexol was about 12.5% that of naltrexone, which was almost in agreement with the efficacies against morphine analgesia in mouse.
CONCLUSIONCompared with naltrexone, 6 beta-naltrexol was less potent but duration was longer.

OBJECTIVEThe theory of treating heart and brain simultaneously is from the theory of traditional Chinese medicine, and there aren't enough explanations for this theory from the perspective of molecular mechanism. As one successful case of this theory, the Chinese medicine formula--Buchang Naoxintong can achieve the goal of treating coronary heart disease and stroke at the same time. To illustrate the mechanism of the theory of treating heart and brain simultaneously, it is necessary to find out the molecular mechanism of this formula.
METHODUsing the network analysis method, together with two data mining methods-clustering and apriori algorithm, the frequent gene combinations interfered by the chemicals of the formula based on the protein-protein interaction networks related with coronary heart disease and stroke disease were figured out respectively. To find out the molecular mechanism of the theory of treating heart and brain simultaneously, the results got from two diseases were compared and analyzed.
RESULTBased on comparing two results from these two different diseases, the mechanism of the theory of treating heart and brain simultaneously was explained from molecular level by finding out key genes targeted by the components of this formula for both diseases and some particular genes interfered by the components for each disease. In addition, genes interfered indirectly by the chemicals for different diseases were found out based on the protein-protein interaction network.
CONCLUSIONIt can help to explain the molecular mechanism of the theory by our methods. By finding out the molecular mechanism of this theory, it can promote the progress of combination of Chinese traditional and Western medicine.
