Objective: To investigate the relationship between serum albumin level and severity of coronary heart disease (CHD). Methods: A total of 237 patients admitted in our hospital from 2008 to 2009 and undergoing coronary angiography were enrolled. CHD severity was evaluated according to clinical types, number of diseased coronary vessels and coronary artery score respectively, and patients were divided into non-CHD group (n=84), angina pectoris group (n=92) and myocardial infarction group (n=61). Serum total protein, albumin and globulin were measured in all patients on second day after admission. Relationship among indexes of CHD severity and serum proteins were analyzed. Results: Compared with non-CHD group, there was significant decrease in albumin level [(40.22±3.56) g/L vs. (39.81±3.56) g/L vs. (38.68±3.43) g/L, P<0.05] in angina pectoris group and myocardial infarction group. Spearman correlation analysis indicated that serum albumin level was significant negatively correlated with clinical types (r=-0.18, P=0.005), number of diseased coronary vessels (r=-0.195, P=0.003) and coronary artery score (r=-0.188, P=0.004). Serum total protein, globulin and ratio of albumin/globulin were not significantly correlated with clinical types, number of diseased coronary vessels and coronary artery score (P>0.05). Conclusion: Serum albumin level is negatively correlated with severity of coronary heart disease. Low serum albumin may be a risk factor for coronary heart disease.

The differences between genders had statistical significance (?~2=19.52,P

Thirteen novel oleanolic acid (OA) derivatives were designed and synthesized with modification at positions of C-3, C-12 and C-28 of OA. Their structures were confirmed by MS, 1H NMR and elemental analysis. Their in vitro cytotoxicities against various cancer cell lines (SGC7901, MCF-7 and A549) were evaluated by MTT assay. The results indicated that the tested derivatives were found to have stronger cell growth inhibitory activity than OA. Among them, compounds II2 and II3 showed more potent cytotoxicity on MCF-7 and A549 tumor cells than gefitinib (positive control). They are worthy to be studied further.

Objective To investigate the relationship between serum 25-(OH) D3 and autoimmune thyroid diseases (AITD).Methods Serum levels of 25-(OH) D3, thyroid antibodies (thyroid stimulating hormone receptor antibody (TRAb), TGAb (thyroid globulin antibody), thyroid peroxidase antibody (TPOAb) and thyroid function of 32 cases patients with Graves' diseases (GD), 17 cases patients without remission of GD,10 cases patients with remission of GD,35 cases patients with Hashimoto's thyroiditis (HT),and 58 cases healthy subjects were measured,and the relationships between serum 25-(OH) D3 and the above clinical index were analyzed.Results The serum level of 25-(OH) D3 in patients with GD or HT were obviously lower than that in healthy subjects((50.75±17.60) μg/L, (36.40±21.65) μg/L, (43.05±19.53) μg/L,P＜0.05).No significant difference of the serum level of 25-(OH) D3 was found between patients refractory of GD and those with GD in remission((32.43±17.50) μg/L, (31.88±14.48) μg/L,P=0.866).However,compared with the normal control group,both diseased groups showed significantly decrease (P＜0.05).No correlation was found between serum 25-(OH) D3 and TRAb, FT3, Fr4 as well as TSH in GD group.No correlation was found between serum 25-(OH) D3 and TGAb, TPOAb (P＞ 0.05).Conclusion Serum vitamin D levels are decreased in patients with AITD, which has been speculated as a potential therapeutic method for AITD, though further investigations are needed to establish the precise role of 25-(OH) D3 in AITD.

The renal toxicity of rats after a single dose ofMeng-Gen-Wu-Su (mercury) processed products,Meng-Gen-Wu-Su (mercury)-18-composition pill, mercuric sulfide, mercuric chloride, and mercurous chloride was studied. Fifty-four male Wistar rats were randomly divided into nine groups according to body weights (6 rats in each group): normal control group, low and high dose groups (0.033, 0.33 g·kg-1·d-1) ofMeng-Gen-Wu-Su (mercury) processed products, low and high dose groups (0.29, 2.9 g·kg-1·d-1) ofMeng-Gen-Wu-Su (mercury)-18-composition pill, simplified prescription ofMeng-Gen-Wu-Su (mercury)-18-composition pill group (0.26 g·kg-1·d-1), mercuric sulfide group (17.39 mg·kg-1·d-1), mercuric chloride group (4.06 mg·kg-1·d-1) and mercurous chloride group (35.3 mg·kg-1·d-1). After acclimation for one week, once oral administration was given to each group of rats. After 24 h, function and morphological changes of liver and kidney were detected. Mercury accumulation in kidney was determined by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma source mass spectrometer (ICP-MS). Apoptosis of renal cell was determined by terminal-deoxynucleoitidyl transferase mediated Nick End Labeling (TUNEL). Renal typeⅢ collagen protein's expression was determined by immunohistochemical (HIC) method and expression changes of MT-1, MT-2 mRNA in kidney were also determined by real-time fluorescence quantitative PCR (real-time-PCR). There was no significant difference of ALT, AST in serum between normal control group and other groups (P>0.05). CREA and UREA in mercurous chloride group were apparently higher than normal control group and low dose group of Meng-Gen-Wu-Su processed products (P<0.01). Hepatic and renal pathologic examination results showed that liver cell of low dose groups ofMeng-Gen-Wu-Su processed products andMeng-Gen-Wu-Su-18-composition pill swelled to a low degree and glomerular disease was not obvious. In high-dose groups ofMeng-Gen-Wu-Su processed products,Meng-Gen-Wu-Su-18-composition pill and mercuric sulfide group, liver and kidney appeared some pathological changes and such changes were more significant in mercuric chloride and mercurous chloride groups. Compared with normal control group and low dose group ofMeng-Gen-Wu-Su processed products, the mercury kidney volume in mercuric chloride and mercurous chloride groups increased significantly (P<0.01). The apoptosis rate of renal cell and expression of typeⅢ collagen protein increased significantly in the groups of mercuric sulfide, mercuric chloride and mercurous chloride (P<0.01). MT-1and MT-2 mRNA gene expression rised significantly in the groups of mercuric chloride and mercurous chloride (P<0.05 orP<0.01). In summary, the rats renal toxicity after a single dose ofMeng-Gen-Wu-Su (Mercury) processed products or MongolianMeng-Gen-Wu-Su (Mercury)-18-composition pill were both far less than that of mercuric chloride or mercurous chloride.

BACKGROUND:Mongolian Pharmaceutical Betel Shisanwei Ingredients Pil has achieved good clinical efficacy, but the underlying mechanism remains unclear. OBJECTIVE: To study the effects of Mongolian Pharmaceutical Betel Shisanwei Ingredients Pil on the hypothalamic-pituitary-adrenal axis negative feedback function in the chronic depressed rats, and to explore anti-depression mechanisms of Mongolian Pharmaceutical Betel Shisanwei ingredients pil. METHODS: Eighty male Wistar rats were randomly divided into ten groups according to the sugar consumption test (with eight rats in each group): normal control group, model group, fluoxetine group, high-, medium- and low-dose Betel Shisanwei Ingredients Pil groups, RU486 group, high-, medium- and low-dose Betel Shisanwei Ingredients Pil plus RU486 groups. Except normal control group, the other groups were treated with the chronic unpredictable mild stress stimulation combined with lonely rising, to establish depression models. In the meantime, rats of the high-, medium- and low-dose Betel Shisanwei Ingredients Pil groups were given oral gavage of Betel Shisanwei Ingredients Pil (0.2, 0.4, 0.8 g/kg) for 28 days; rats of the normal control group and model group were intragstricaly administered with sodium carboxymethyl celulose; rats of RU486 group were given abdominal subcutaneous injection of RU486 from day 21 after modeling; rats of the high-, medium- and low-dose Betel Shisanwei Ingredients Pil plus RU486 groups were intragstricaly administered with Betel Shisanwei Ingredients Pil (0.2, 0.4, 0.8 g/kg) and subcutaneous injection of RU486 from day 21. RESULTS AND CONCLUSION:Compared with normal control group, cortisone content increased significantly (P < 0.05), the expression of glucocorticoid receptor mRNA in hippocampus, hypothalamus and pituitary gland decreased significantly, and hypothalamic corticotrophin releasing hormone mRNA expression increased significantly in the model group and RU486 group. Compared with model group, cortisone content decreased, the expression of glucocorticoid receptor mRNA in hippocampus, hypothalamus and pituitary gland increased significantly, and hypothalamic corticotrophin releasing hormone mRNA expression decreased significantly in rats treated with Betel Shisanwei Ingredients Pil. Compared with RU486 group, Betel Shisanwei Ingredients Pil administration led to changed in cortisone content, glucocorticoid receptor mRNA expression in hippocampus, hypothalamus and pituitary gland, as wel as hypothalamic corticotrophin releasing hormone mRNA expression. Experimental findings indicate that, Betel Shisanwei Ingredients Pil can directly regulate excessive secretion of glucocorticoid, and improve the dysfunction of hypothalamic-pituitary-adrenal axis central negative feedback through increasing glucocorticoid receptor mRNA expression and decreasing corticotropin releasing hormone mRNA expression. After the hypothalamic-pituitary-adrenal axis negative feedback pathway is blocked, the effect of Betel Shisanwei Ingredients Pil is weakened.
