OBJECTIVETo observe the change of lipid metabolism and vascular endothelium as well as morphology of heart tissue in rats who were long-time exposed to moxa smoke with different concentrations in order to provide reference for safety assessment of moxa smoke on cardiovascular system.

METHODSOne hundred and sixty-eighty Wistar rats were randomly divided into a control group, a low-concentration group, a median-concentration group and a high-concentration group, 42 rats in each one. The rats were exposed to moxa smoke with concentration of 0%, 10%, 40% and 70%, respectively, for 20 min per day. After continuous intervention for six months, enzyme-linked immunosorbent assay (ELISA) was applied to measure the level of low density lipoprotein-receptor (LDL-r) and intercellular adhesion molecule-1 (ICAM-1) in blood serum in each group; the slices of heart tissue were stained with hematoxylin-eosin staining method to observe morphology change of heart tissue.

RESULTS(1) After the intervention of moxa smoke, the levels of LDL-r and ICAM-1 in the low-concentration group were not statistically different from those in the control group (both P > 0.05); the level of LDL-r in the median-concentration group was significantly increased, which was statistically different from that in the control group [(3.87 +/- 0.27) mg/mL vs (2.12 +/- 0.13) mg/mL, P < 0.01], however, the content of ICAM-1 was not obviously changed; although the level of LDL-r in the high-concentration group was presented with an escalating trend, it was not statistically different from that in the control group (P > 0.05) while the level of ICAM-1 was obviously increased (P < 0.01). (2) Under the light microscope, the abnormalities of cardiac muscle fibers and myocardial cell in each group were not been observed.

CONCLUSIONThe long-time intervention of low-concentration moxa smoke has no significant effects on lipid metabolism and vascular endothelium of rats, indicating that clinical application of low-concentration moxa smoke is relatively safe. The long-time intervention of moderate-concentration moxa smoke could significantly increase the clearance rate of cholesterol, implying the beneficial regulation of moxa smoke on lipid metabolism. The high-concentration moxa smoke could induce certain damage to vascular endothelium but its mechanism is in need of further research. The pathologic change of heart tissue could not be induced by moxa smoke with any concentration.

OBJECTIVETo explore the effects of Yizhi Capsule (YZC) on learning and memory disorder and beta-amyloid peptide induced neurotoxicity in rats.

METHODSVarious doses of YZC were administered to Sprague-Dawley (SD) rats for 8 consecutive days, twice a day. On the 8th day of the experiment, scopolamine hydrobromide was intraperitoneally injected to every rat and Morris water maze test and shuttle dark avoidance test were carried out respectively to explore the changes of learning and memory capacities in the rats. Besides, after the cerebral cortical neurons of newborn SD rats aged within 3 days were cultured in vitro for 7 days, drug serum containing YZC was added to the cultured neurons before or after beta amyloid peptide(25 - 35) (Abeta(25 - 35)) intoxication to observe the protective effect of YZC on neurotoxicity by MTT assay and to determine the LDH content in the supernatant.

RESULTSCompared with those untreated with YZC, the rats having received YZC treatment got superiority in shorter time of platform seeking in Morris water maze test, as well as elongated latent period and less times of error in shuttle dark avoidance test. On the cultured neurons, YZC drug serum could effectively increase the survival rate of Abeta(25 - 35) intoxicated neurons and reduce the LDH contents in cultured supernatant.

CONCLUSIONYZC has an action of improving learning and memory disorder, and good protective effect on Abeta(25 - 35) induced neurotoxicity in SD rats.

Objective To establish and evaluate two protocols for the noninvasive visualization and assessment of coronary artery bypass graft (CABG) patency on electron beam tomography (EBT).Methods Two hundred and fourteen consecutive patients who underwent coronary artery bypass graft surgery were scanned using both EBT angiography with 3-dimensional reconstruction and EBT flow study with time-density-curve analysis.Results There were 589 CABGs evaluated in this study (10 grafts were excluded because of artifacts). Among them, 133 (98.5％) of 135 arterial grafts were patent, and 345 (77.7％) of 444 saphenous-vein grafts were patent. Within 5 years or between 5 and 10 years after operation, arterial graft patency exceeded venous graft patency (P ＜ 0.001 ). Three-dimensional EBT angiography achieved higher sensitivity, specificity and accuracy (97.7％, 94.1％ and 96.7％, respectively) than did EBT flow study (88.4％, 82.4％ and 85.2％, respectively) for evaluating occlusion or patency of CABG. The intra-graft flow of patent arterial and venous grafts were 4.9 ± 2.2 mi · min-1 · g-1 and 6.9 ± 2.8 mi · min-1 · g-1,respectively (P＜0.001).Conclusion The combination of EBT three-dimensional reconstruction and flow study can be more effective in the assessment of CABG anatomy and quantification of patent CABG blood flow.

OBJECTIVETo investigate the expression of androgen receptor (AR) and hepatitis B virus X protein (HBx) in hepatocellular carcinoma (HCC), and analyze the relationship between AR and HBx expressions.

METHODSTumor tissues and peritumoral tissues of 83 HBV-associated HCC cases were investigated in this study. Fourteen cases of HBV-negative HCC and 13 cases of hemangioma peritumoral tissues were considered as control. AR and HBx mRNA levels were determined by quantitative fluorescence real-time RT-PCR and their protein levels were assayed by Western blot. The expression of AR and HBx proteins in tissues were examined with EnVision immunohistochemical staining. The methylation status of AR promoter was determined using methylation-specific PCR (MSP).

RESULTSBoth expression levels of AR mRNA and protein of the peritumoral tissues were significantly higher (0.17) than that of tumor tissues (0.09) in HBV-associated HCC (P < 0.01), but such a difference was not found in HBV-negative HCC (0.06 vs. 0.07, P > 0.05). The level of AR expression in peritumoral tissues was associated with tumor differentiation in HBV-associated HCC. AR mRNA and protein levels of peritumoral tissues in HBV-associated HCC were significantly higher than that in HBV-negative HCC and hemangioma (all P < 0.05). In the tumor tissues, HBV-associated HCC had significantly higher AR expression than HBV-negative HCC at mRNA level (P < 0.05), but not at protein level. Spearman rank correlation analysis showed that the AR mRNA or AR protein levels were positively correlated with HBx in both tumor and peritumoral tissues in HBV-associated HCC, but the expressions of AR and HBx were not associated with AR promoter methylation status. The relative expression levels of AR mRNA and protein in the HBV-associated peritumoral tissues were negatively correlated with tumor differentiation (r = -0.213, P < 0.05; r = -0.313, P < 0.05), the higher the AR expression, the poorer differentiation. But this correlation of AR mRNA and protein was not shown in the hepatocellular carcinoma tissues.

CONCLUSIONSHBx may enhance AR expression in HBV-associated HCC, but AR promoter demethylation maybe not been involved in its main mechanism. An increased AR expression is probably an early event during the development and progression of HBV-associated HCC, and AR expression in the peritumoral tissue is correlated with HBV-associated HCC differentiation. AR may play different roles in HBV-associated HCC and HBV-negative HCC.
