Objective To investigate the expression of inducible nitric oxide synthase (iNOS) and p53 protein in hepatocellular carcinoma (HCC) and their relationship with angiogenesis. Methods Immunohistochemical method and image analysis technique were used to detect the expression of iNOS and p53 protein in tumor tissue sections of 59 HCC patients. Microvessel density (MVD) was counted by immunohistochemical staining with anti CD34 antibody.Results ①The expression rates of iNOS and p53 were 81.4%(48/59), 64.4%(38/59) in HCC patients, respectively. The expression intensities of iNOS and p53 were 5 635?1 287, 3 352?873 in HCC patients, respectively. ②MVD was 32.5?2.73 in the tumor tissue of HCC patients. ③The expression of iNOS was correlated with the expression of p53 and MVD in HCC patients ( P

The association of polymorphisms of calcium channel?1 subunit ( Cav1.1 ) gene ( - 1551T/C at exon 11 ) with thyrotoxic periodic paralysis (TPP) was investigated by PCR-RFLP.The distributions and frequencies of - 1551TC + CC genotype and C allele in TPP group were significantly higher than those in hyperthyroidism (HT) and normal control (CON) groups.There was no statistic difference between HT and CON groups.Cavl.1 gene - 1551TC + CC genotype and allele may contribute to the development of TPP in male HAN population from North China.

Objective To compare the effects of different antiplatelet therapy on outcomes in patients with acute coronary syndrome (ACS). Methods 338 hospitalized patients with ACS were enrolled. They were assigned to three groups: group 1, aspirin alone after discharge, n=93; group 2, dual antiplatelet treatment of aspirin and clopidogrel after discharge for 6～12 months, then aspirin, n=127; and group 3, dual antiplatelet treatment of aspirin and clopidogrel after discharge for 2 years, n=118. All the patients were followed up for 2 years. The clinical data (basic clinical data, platelet count and serum lipids indeices), primary end point (cardiovascular death, nonfatal myocardial infarction and stroke) and hemorrhagic events (major hemorrhage, moderate hemorrhage and minor hemorrhage) within 1 and 2 years were analyzed. Results During 1 and 2 years, compared with group 1, the incidence of cardiovascular death and all primary end points of groups 2 and 3 decreased significantly (P＜0.05), but the nonfatal myocardial infarction and stroke did not （P＞0.05）. The difference was not statistically significant between groups 2 and 3 in all the end points （P＞0.05）. The difference of hemorrhagic events was not statistically significant among the 3 groups（P＞0.05）. Conclusion Dual antiplatelet treatment of clopidogrel plus aspirin for 2 years may decrease the mortality of cardiovascular disease while the incidence of severe hemorrhage doesn't increase.

In order to establish a method for the determination of the sterols of the oil in the freeze-dried acai (Euterpe oleracea Mart.) and to evaluate its antioxidant activities, a saponification/extraction procedure and high performance liquid chromatography (HPLC) analysis method were developed and validated for the analysis of phytosterols in PEE (Petroleum ether extract). Separation was achieved on a Purosper STAR LP C18 column with a binary, gradient solvent system of acetonitrile and isopropanol. Evaporative light scattering detection (ELSD) was used to quantify β-sitosterol and the total sterols. Peak identification was verified by retention times and spikes with external standards. Standard curves were constructed (r = 0.999 2) to allow for sample quantification. Recovery of the saponification and extraction was demonstrated via analysis of spiked samples. The highest content of total sterols is β-sitosterol. The antioxidant activities of the extracts were evaluated using the total oxyradical scavenging capacity assay (TOSC assay). The result showed that the PEE exhibited significant antioxidant properties, sample concentration and the antioxidant capacity had a certain relevance.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.
