Objective To analyze the relationship between the distribution of visceral adipose and cardiovascular damage in the patients with metabolic syndrome. Methods 108 in-patients were categorized according to the diseases, they were suffering from into metabolic syndrome group (MS, 70 cases), essential hypertension group (EH, 22 cases), and type 2 diabetes mellitus group (T2DM, 16 cases). The areas of both visceral adipose (VA) and subcutaneous adipose (SA) were measured for all the three groups, and then VA/SA was calculated. The relationship of the above variables with left ventricular mass (LVM), LVM-index (LVMI) intima-medial thickness (IMT) of carotid artery, and myocardial ischemia was analysed. Results Compared with T2DM and EH groups, the area with VA was significantly larger in MS group (P

To study the effect of vascular proliferation and reconstruction in chronic hepatitis B (CHB), immunohistochemical staining and in situ hybridization were used. The expression of transforming growth factor (TGF-?1) and smooth muscle actin (?-SMA) in livers of CHB were observed. The results showed that TGF-?1 and ?-SMA were related with degeneration of hepatocytes, intrahepatic vascular fibrosis and hepatic sinusoidal capillarization. The expression degree and range of TGF-?1 and ?-SMA increased with the exacerbation of liver lesion. These results suggest that vascular proliferation and reconstruction may play important roles during the process of CHB.

Purpose To investigate the expression of c-myc and MDM2 protein in multiple myeloma (MM) and their correlation with clinical stage.Methods Immunohistochemical SP three-step method was used to detect the expression of MDM2 and c-myc protein in 60 cases of MM with different clinical stages and 10 cases of nontumorous bone marrow tissue.Results The positive rate of c-myc protein in MM and nontumorous bone marrow tissue were 71.7％ and 10.0％;the positive rate of MDM2 protein in two tissues were 80.0％ and 20.0％,respectively.The expression difference of two proteins between MM and nontumorous bone marrow tissue was statistically significant (P ＜ 0.05).The expression of c-myc and MDM2 protein was positively correlated with MM clinical ISS stage (P ＜ 0.05),but irrelevant with the age and gender.The expression of c-myc and MDM2 protein in MM was positively correlated (P ＜ 0.05).Conclusion The c-myc and MDM2 protein have a highly expression in MM,and it may be relative to the occurrence of MM and clinical stage.In the MM,c-myc and MDM2 protein may have synergetic functions and promote the development of tumor.

OBJECTIVE:To study the in vitro dissolution of Enalapril maleate and folic acid tablet. METHODS:HPLC was performed on the column of Agilent HC-C18 with mobile phase A of acetonitrle-phosphate buffer solution(70:30,V/V) and mobile phase B of acetonitrle-phosphate buffer solution(5:95,V/V)(gradient elution) at a flow rate of 1.0 ml/min,detection wavelength was 215 nm,column temperature was 50 ℃,and volume injection was 80 μl. Media were water,hydrochloric acid solution(pH 1.2),phosphate buffer solution(pH 5.0)and phosphate buffer solution(pH 6.8),medium volume was 900 ml and rotation speed was 50 r/min. The dissolution behavior of enalapril maleate in Enalapril maleate and folic acid tablet in 4 media were studied and compared with the dissolution behavior in vitro in original preparation of Enalapril maleate tablet,meanwhile,the dissolution behar-ior of folic acid in Enalapril maleate and folic acid tablet in phosphate buffer solution(pH 5.0)were studied and compared with dis-solution data of folic acid preparation in Japanese Orange Book to evaluate the intrinsic quality. RESULTS:The linear range was 0.561-14.03μg/ml for enalapril maleate(r=0.999 9)and 0.043-1.085μg/ml for folic acid(r=0.999 9),respectively;RSDs of pre-cision and stability tests were lower than 2.0%;recoveries of enalapril maleate in 4 media were 100.63%-102.33%(RSD=0.72%, n=9),99.27%-100.44%(RSD=0.41%,n=9),99.71%-100.29%(RSD=0.15%,n=9)and 96.74%-99.19%(RSD=0.79%,n=9),respectively. Recoveries of folic acid were 100.18%-101.63%(RSD=0.48%,n=9),97.73%-101.81%(RSD=1.32%,n=9),99.60%-102.24%(RSD=0.74%,n=9)and 100.00%-102.76%(RSD=0.90%,n=9),respectively. In 15 min,the dissolution of enalapril maleate of 2 preparations in 4 dissolution media were more than 85%;dissolution speed of folic acid in Enalapril male-ate and folic acid tablet was faster than that in folic acid preparation in phosphate buffer solution(pH 5.0).

Objective: To investigate the effects of Radix Ginseng and Radix Notoginseng formula on secretion of vascular endothelial growth factor (VEGF) and expression of vascular endothelial growth factor receptor-2 (VEGFR-2) in human umbilical vein endothelial cells (HUVECs) in vitro. Methods: HUVECs were cultured in vitro. Bovine basic fibroblast growth factor (bFGF) at concentration of 320 U/mL and Radix Ginseng and Radix Notoginseng formula at concentrations of 0.1, 0.2 and 0.4 mg/mL were used to culture with HUVECs. And HUVECs in blank control group were cultured with culture solution only. After 24-hour culture, the content of VEGF in supernatant was detected by enzyme-linked immunosorbent assay and the expression of VEGFR-2 was detected by immunocytochemical staining and Western-blotting. Results: Radix Ginseng and Radix Notoginseng formula at 0.4 mg/mL, the same as bFGF, increased VEGF content in the HUVEC supernatant and the number of VEGFR-2-positive HUVECs. Expression of VEGFR-2 protein in high-dose Radix Ginseng and Radix Notoginseng formula group was up-regulated as compared with the blank control group. Conclusion: Radix Ginseng and Radix Notoginseng formula can promote HUVEC proliferation and secretion of VEGF, as well as the expression of VEGFR-2 protein, which may be one of the mechanisms of Radix Ginseng and Radix Notoginseng formula in promoting angiogenesis.

Objective To observe the effects of electroacupunture (EA) on the abnormal hypothalamus-pituitary-adrenal (HPA) axis and the expression of hypothalamic corticotropin-releasing factor (CRF) peptides family and CRF receptor (R)1 mRNA in traumatized rats,so as to study its underlying mechanism in improving traumatic injury. Methods Forty male Sprague-Dawley rats were randomly divided into normal control group (n=10),normal+ EA group (n=10),surgical trauma (model) group (n=10),and model+EA group (n=10). Traumatic injury model was established by performing an exploratory laparotomy in the rats under anesthesia. EA (2 Hz/15 Hz,1-2 mA) was administered for 30 min via two stainless steel needles inserted in "Zusanli" (ST 36) and "Sanyinjiao" (SP 6). Serum adrenocorticotropic hormone (ACTH) ,corticosterone (Cort),luteinizing hormone (LH) and testosterone (T) contents were detected by double-antibody radioimmnoassay. Hypothalamic CRF and CRF R1 mRNA expression was assayed by reversed transcription polymerase chain reaction (RT-PCR) technique. Results The serum ACTH concentration decreased significantly in model group (P0.05). The serum Cort level increased significantly in model group(P0.05). The expression of hypothalamic CRF mRNA decreased significantly in model group (P0.05). Conclusion EA of "Zusanli" (ST 36) and "Sanyinjiao" (SP 6) can improve surgical trauma-induced HPA disorders,which is probably related to its effects in upregulating CRF mRNA expression and downregulating Ucn 1 mRNA expression in the hypothalamus.
