Objective To investigate the effects of S-allylcysteine ( SAC ) , on nitric oxide ( NO ) production and antioxidant enzyme activities in hyperlipidemic rats. Methods Male Wistar rats were randomly divided into seven groups. Five groups including normal control group ( normal diet) , model control group ( high-fat diet, HFD) and SAC low,medium,high treated group (high-fat diet +25,50,100 mg·kg-1 SAC) were sacrificed after 4 weeks dosing,while the other two groups including L-arginine group (normal diet+ 20 mg·kg-1 L-arginine) and SAC+L-arginine group (50 mg·kg-1 SAC+20 mg·kg-1 L-arginine) were sacrificed at 4 h after dosing. The serum, livers and kidneys were collected. The levels of NO, the activities of nitric oxide synthase ( NOS ) , antioxidant enzymes in vivo and L-arginine contents in serum were determined. Results Comparing with model control group, the activities of total NOS in serum and liver were significantly reduced in SAC-treated groups (P<0. 05). The level of L-arginine in SAC-treated groups was (8. 25 ± 1. 15), (7. 76 ± 1. 24) and (7. 22 ± 1. 64)μg·mL-1 , respectively. Compared with model control group, the level of L-arginine were significantly reduced in SAC-treated groups (P<0. 05). Comparing with L-arginine group, the activities of total NOS (T-NOS) and iNOS were reduced in SAC+L-arginine group. SAC treatment (100 mg·kg-1) significantly increased the activities of superoxide dismutase (SOD) (P<0. 01) and the level of glutathione (GSH) (P<0.01), and decreased the level of malondialdehyde (MDA) in serum and liver of hyperlipidemic rats. Conclusion These data suggest that SAC inhibits the NO production by reducing iNOS activity, arginine concentration and exhibited antioxidant activity, which may play a pharmacologically important role in protection from oxidative injury and pathogenesis of atherosclerosis.

[ ABSTRACT] AIM:To investigate the effect of Jia-jian-yi-yin decoction on endothelium-dysfunction in ovariecto-mized rats.METHODS:The ovariectomized rats were treated with Jia-jian-yi-yin decoction or turbid liquid of estradiol va-lerate for 8 weeks.The vascular ring tension was measured.Scanning electron microscopy and Western blotting were ap-plied to assess the function of endothelium-dependent dilation, aortic endothelial morphology and the expression of endothe-lial lipase.The pathologic sections were prepared to observe the effect of Jia-jian-yi-yin decoction on the uterus.RE-SULTS:In ovariectomized rats, the decrease in endothelium-dependent relaxation to acetylcholine ( ACh) was reversed to normal level, the endothelial morphology returned to normal without lipid accumulation and the endothelial lipase expression was decreased by Jia-jian-yi-yin decoction.Furthermore, no obvious change of the wet weight of uterine between the ovari-ectomized rats with or without Jia-jian-yi-yin decoction treatment was observed.CONCLUSION:Jia-jian-yi-yin decoction may have protective effects on endothelium-dependent vasodilation and aortic endothelial morphology in estrogen-deficient animals.

The incidence of nonalcoholic fatty liver disease (NAFLD) has been increasing in China year by year, and NAFLD has become the second most common liver disease after viral hepatitis. Its development is closely associated with insulin resistance and oxidative stress and NAFLD is one of the important components of metabolic syndrome. Ghrelin is a newly discovered endogenous ligand for growth hormone secretagogue and has broad biological functions. Ghrelin not only affects the metabolic process of glucose and lipids, but also plays an important role in the development and progression of NAFLD. In this review, the role of endogenous Ghrelin expression in the development and progression of NAFLD is briefly summarized and the Ghrelin regulation in the development and progression of NAFLD is pointed out, which will provide new approaches to the clinical treatment of NAFLD.

Objective To construct a prognostic nomogram for predicting the prognosis of patients with colorectal cancer ( CRC) , and verify its accuracy. Methods The clinical pathologic data from 438 CRC patients hospitalized in the Third Affiliated Hospital of Soo-chow University during January 2006 and May 2013 were retrospectively analyzed. The independent risk factors for predicting the prog-nosis of CRC were determined by the univariate and multivariate regression model. The prognostic nomogram was established by the R-language software. Then, the nomograms of postoperative 3-year and 5-year disease free survivals ( DFS) were drawn, and compared with the actual status. The internal validation and accuracy of the nomogram were determined by the Bootstrap method and the calculat-ed concordance index ( C-index) , respectively. The sensitivity and specificity of the nomogram for predicting the 3-year and 5-year DFS were compared with those of TNM system established by the American Joint Committee On Cancer (AJCC) (7th ed.) by using the time-dependent ROC curve. Results Among 438 CRC patients, the metastasis of CRC occurred in 233 patients, including 105 liver metas-tasis and 57 lung metastasis. Multivariate COX regression analysis showed that tumor differentiation degree, TNM stage, serum CEA level, serum CA19-9 level, neutrophil lymphocyte ratio ( NLR) and P53 level were the independent risk factors of CRC. The C-index of the constructed nomogram for predicting the survival rate of CRC patients was 0.678. The predicted 3-year and 5-year DFS by the no-mogram were highly coincident with the actual status. The analysis results of the time-dependent ROC curve showed that the sensitivity and specificity of the established nomogram for predicting the postoperative 3-year and 5-year DFS were higher than those of AJCC-TNM stage.Conclusion The established nomogram may accurately predict the prognosis of CRC patients, which may be helpful for clinicians to follow up or make beneficial treatment for CRC patients.

Objective To explore a new efficient extraction method of dorsal root ganglions(DRGs)of rats by exploring and extracting DRGs reversely along the nerve traveling pathway. Methods The DRGs were extracted by the traditional method of opening the intervertebral foramina and the new method, extracting DRGs reversely along the nerve traveling pathway,respectively. The time consuming and the number of intact DRGs obtained with these two method were compared. Results The number of intact DRGs(L3-5segments,both sides)extracted from each rat with the traditional method was(3.08 ± 1.31),and the average time consuming of each DRG was(5.58 ± 1.21)min. As for the new method ,the number of intact DRGs extracted from each rat was(4.29 ± 1.08), and the average time consuming was(1.69 ± 0.91)min,significantly better than that of the traditional method(P < 0.05 for both). Conclusions The new method of exploring and extracting DRGs reversely along the nerve traveling pathway is more efficient for obtaining intact DRGs of rats,providing more useful tissue materials for subsequent culture and morphological studies of DRG cells.

Objective To evaluate the significance of AFP-IgM, this is one of new tumor markers, in the diagnosis of primary hepatocellular carcinoma (PHC). Methods The contents of AFP-IgM and AFP in serum of 103 healthy subjects, 74 patients suffered primary hepatic carcinoma, 27 patients affected by liver cirrhosis and 63 patients affected by chronic hepatitis were detected by means of enzyme linked immunosorbent assay and electrochemiluminescence. No-PHC is comprised of liver cirrhosis,chronic hepatitis and health subjects as control group. Results The area under ROC curve of AFP was larger than that of AFP-IgM (0.85 vs 0.72, Z=3.21) and the best cut-off value of AFP-IgM and AFP was 3×105-AU/L and 10 ug/L respectively, which was determined by ROC curve. Under the cut-off value, the sensitivity of AFP- lgM and AFP for PHC were 64.9% and 79.7%, and the specificity were 75.6% and 80.3%, yet their efficacies were similar. However, for early diagnosis of liver cancer (stage Ⅰ and Ⅱ), the area under ROC curve of AFP-IgM was larger than that of AFP (0.91 vs 0.82,Z=1.73). The sensitivity of AFP-IgM andAFP were 94.4% and 72. 2%, and the specificity were 81.9% and 79.9%. The differences of AFP-IgMand AFP for early diagnosis of liver cancer were statistically significant. When both of the test results combined AFP-IgM with AFP are positive, it can be diagnosed as liver cancer. The specificity of combineddetermination of the two forms was 89.1%, and the efficacy was 79. 0%. Conclusions Both of thesensitivity and specificity of the AFP-IgM test were higher than that of the AFP for early diagnosis of livercancer. We also found that combined determination of the two forms significantly increased the specificityand the positive predictive value for the diagnosis of PHC, thus AFP-IgM was of especially significance forearly diagnosis of liver cancer.
