OBJECTIVETo investigate the effects of stellate ganglion block (SGB) on blood pressure in spontaneously hypertensive rats(SHRs).

METHODSThirty-two 10-week-old male spontaneously hypertensive rats(SHRs) were assigned randomly into four groups: left stellate ganglion block group(Group LS), right stellate ganglion block group(Group RS), captopril group(Group D) and control group(Group C). Arterial systolic blood pressure(SBP) was measured, and endothelin (ET-1) and endothelial nitric oxide synthase(eNOS) in blood vessels were detected by radioimmunoassay.

RESULTSCompared with baseline value, the blood pressure of Group LS gradually increased significantly (P<0.05 or P <0.01); however, the blood pressure of Group RS was stable(P >0.05) and increased only at week 2(P <0.05).The blood pressure of Group D decreased significantly at week 2 and week 4, and it remained stable compared with baseline value (P<0.05). The blood pressure of Group C gradually increased at weeks 2-10, compared with baseline values (P <0.01). Compared with Group LS and Group C, the expression of eNOS in blood vessels of Group RS significantly increased (P <0.05), and ET-1 decreased (P <0.05).

CONCLUSIONThe right stellate ganglion block can significantly lower blood pressure, down-regulate ET-1 and up-regulate eNOS protein expression.

Objective:To understand the molecular pat hophysiology of hepatocellular carcinoma and pancreatic cancer.Methods: We studied novel gene expression by cDNA microarray method. The PCR pro ducts of 4 096 genes and 12 800 gene were spotted onto a kind of chemical-mater ial-coated-glass slide in array. Both the mRNAs from 5 cases of hepatocellular carcinoma and 3 cases of pancreatic cancer were reversely transcribed to cDNAs with the incorporation of fluorescent-labeled dUTP to prepare the hybridization probes. After hybridization, BioDoor4096 and BioDoor12800 cDNA microarray were scanned for the fluorescent intensity. Tumor invasion-related gene expression w as screened through the analysis of difference in gene expression profile.Results:Among 4 096 and 12 800 target genes, there were 15 genes who se expression level differed from normal and carcinoma tissues. Therefore, they might be associated with metastasis.Conclusion:Further analysis of these differentially expressed metastasis-associated genes will be helpful for understanding the molecular mechanism of malignant carcinoma.

AIM:To investigate the change of late sodium current (INaL) and the effect of Ca2+/calmodulin-dependent protein kinaseⅡ (CaMKⅡ) inhibitor KN-93 on INaLin the cardiomyocytes after isoproterenol-induced heart fai-lure (HF) in rabbits. METHODS:The rabbit model of HF was induced by injecting isoproterenol (300 μg·kg-1· d-1) for 15 d. One month later, all rabbits received by echocardiography and HE staining to observe the morphological changes of myocardium for evaluating the HF model. The protein expression of NaV1.5, CaMKⅡδ and phosphorylated CaMKⅡδ was determined by Western blot. The ventricular myocytes were isolated from the rabbits of normal saline(NS) group and HF group by Langendorff perfusion, and the whole-cell patch-clamp technique was used to record INaL. RE-SULTS:Compared with NS group,the heart rate in HF group was increased (P<0.01), the ventricular cavity was en-larged (P<0.05),and the cardiac function was decreased(P<0.01). Compared with NS group,the cardiomyocytes in HF group arranged in disorder, vacuolar degeneration and myocardial interstitial edema were observed, and fibrous tissue increased. The protein levels of NaV1.5,CaMKⅡδ and phosphorylated CaMKⅡδ in HF group were higher than those in NS group(P<0.01). INaLin HF group significantly increased compared with NS group (P<0.01). After adding sea anemone toxin Ⅱ (ATXⅡ), the density of INaLin HF group and NS group was significantly increased, but that in HF group increased more obviously than that in NS group (P<0.01). After ATXⅡ had induced stable current, we added KN-93 into NS group and HF group,and we found that the ATXⅡ-increased INaLin NS group and HF group was signifi-cantly decreased(P<0.05).CONCLUSION:CaMKⅡinhibitor KN-93 inhibits the increase in INaLin HF rabbits,which may be related to the activity of CaMKⅡδ and the regulation of CaMKⅡ δ on INaL.

OBJECTIVETo evaluate the anginal attack-relieving efficacy and safety of Kuanxiong Aerosol (KA) in patients with coronary heart disease (CHD).

METHODSA total of 780 patients confirmatively diagnosed as CHD angina from November 2011 to December 2012 in 13 medical centers in the mainland area were assigned to 2 groups by blocked randomization, the treatment group (376 cases) and the control group (374 cases). When the angina attacked, patients in the treatment group received sublingual spray three times, 0.6 mL each time, while those in the control group sublingually dissolved Nitroglycerin Tablet (NT), 0.5 mg each tablet. The effective rate of angina relief, efficacy of electrocardiogram (ECG), and the incidence of adverse reactions were observed.

RESULTSThe 3 min and 5 min remission rates of angina attack were 53.72% (202/376) and 94.41% (355/376) in the treatment group, and 47.86% (179/374) and 90.64% (339/374) in the control group. The 95% confidence interval (CI) of the difference between the 2 groups of 3 min and 5 min remission rates of angina attacks were [(-1.84%, 12.32%) and (-1.33%, 6.85%) respectively, P > 0.05]. The total improvement rates of ST-T changes in the treatment group and the control group after treatment were 74.07% and 73.13% respectively (P > 0.05). The adverse reaction rate was 9.31 (35/376 cases) in the treatment group and 22.46% (84/374 cases) in the control group (P < 0.01).

CONCLUSIONKA was not inferior to NT in relieving anginal attacks and improving ischemic ECG changes, and had obviously less adverse reaction.

Connexin (Cx), a multigene-encoded transmembrane protein family, forms either gap junctions ( GJ) or hemichannels (HC) to mediate intercellular communication in plasma mem¬brane between adjacent cells or interacts with proteins by its car- boxyl terminal in the cytoplasm to participate in the process of tumor cell proliferation, apoptosis, necrosis, invasion, metasta¬sis, drug resistance and stem cell characteristics.However, mi- slocalization of Cx in cytoplasm or nucleus often occurs in many tumors, and involved in the occurrence and development of tumors.Subcellular localization of Cx is affected by post-transla- tional modifications, including phosphorylation, ubiquitination, and acetylation.In this paper the classification and function of Cx, the relationship between subcellular localization of Cx and tumorigenesis and the regulation of post-translational modifica¬tion on Cx are reviewed in order to provide new ideas for the study of Cx as a potential target for cancer therapy.

Objective To investigate the expression of Cripto-1 in pancreatic cancer and to analyze its clinical significance. Methods Cripto-1 expression in normal pancreas,pancreatic cancer and adjacent non-tumor tissues,chronic pancreatitis tissues and other related tissues was evaluated using immunohistochemistry.The association of Cripto-1 expression with the clinicopathological characteristics and the prognostic value of Cripto-1 in patients with pancreatic cancer were analyzed. Results The expression of Cripto-1 was higher in chronic pancreatitis tissues,pancreatic cancer and its metastases than in normal pancreas(P=0.019,P=0.025,and P=0.018,respectively).Cripto-1 overexpression was correlated with poorly differentiated pancreatic cancer.The patients with Cripto-1 upregulation had shorter median survival time(8 months vs.16 months,χ

To investigate the effect and mechanism of miR-498 on Th17 cell differentiation of peripheral blood mononuclear cells (PMBCs) in rheumatoid arthritis (RA) patients, peripheral blood samples were collected from RA patients and healthy controls, respectively. The proportion of CD4IL-17 T cells (Th17 cells) or CD4FOXP3 T cells (Tregs) in T cells and the Th17/Treg ratio were identified by the flow cytometer. The STAT3 and miR-498 expression were measured by Western blot and real-time PCR, respectively. ELISA was used to detect IL-17 concentrations. Luciferase assay was performed to confirm that miR-498 directly targeted the 3' untranslated region (3'UTR) of STAT3 in CD4 T cells. The effect of miR-498 on Th17 cell differentiation was explored by transfection of miR-498 mimic and/or pcDNA-STAT3 into CD4 T cells. In PMBCs of RA patients, the Th17/CD4 T cell ratio was significantly increased, while the Tregs/CD4 T cell ratio was obviously decreased, leading to a higher Th17/Treg ratio. The results showed a reduced miR-498 expression and an increased STAT3 protein expression in PMBCs, and an increased IL-17 concentration in serum of RA patients. In cells transfected with wild-type-STAT3-LU, miR-498 mimic significantly reduced the luciferase activity, STAT3 gene and protein expression, and miR-498 inhibitor had an opposite function. While the miR-498 mimic/inhibitor had no effect on the luciferase activity and STAT3 expression in cells transfected with mutant-STAT3-LU. CD4 T cells transfected with miR-498 mimic had a lower Th17/CD4 T cell ratio and IL-17 concentration, however, transfection of pcDNA-STAT3 reversed the effect of miR-498 mimic on Th17/CD4 T cell ratio and IL-17 concentration. These results suggest that overexpression of miR-498 suppresses Th17 cell differentiation by targeting STAT3 in RA patients.
