Objective To investigate the effects of bisoprolol combined with rosuvastatin on endothelial function and inflammation in patients with coronary slow flow (CSF). Methods Ninety CSF patients treated from August 2014 to October 2015 were randomly divided into control group, statin group and combined group, thirty cases in each group. The control group was given conventional therapy (aspirin 100 mg/d and isosorbide mononitrate 60 mg/d), statin group was given rosuvastatin 10 mg/d on the basic of control group, while the combined group was given bisoprolol 5 mg/d on the basic therapy of statin group. The serum concentrations of nitric oxide (NO), endothelin-1(ET-1), high-sensitivity c-reactive protein (hs-CRP) and interleukin-6 (IL-6) were detected before treatment and 8 weeks after treatment. The improvement of patients with angina pectoris was evaluated. Results After eight-week treatment, the NO levels were significantly increased in combined group and statin group, while the ET-1, hs-CRP and IL-6 levels were significantly decreased than those before the treatment (P<0.05). At the same time, comparing with the statin group and control group, the NO level was increased in combined group (P<0.05), while the ET-1, hs-CRP, and IL-6 levels decreased significantly (P<0.05). There were significant differences in the effective rates between the combined group (90.0%) and the statin group (83.3%), which were higher than those in control group (56.7%). Conclusion Bisoprolol combined with rosuvastatin can improve the endothelial function and anti-inflammatory in the treatment of CSF.

Objective: To provide an effective hGM CSF gene transferring vector mediated by gene gun and a basis for study of hGM CSF gene modified tumor cell vaccines. Method: The gastric tumor cell line (SGC) was transfected with eukarytic expression plasmid deoxyribonucleic acid containing the human granulocyte macrophage colony stimulating (hGM CSF) gene using the gene gun. The SGC cell clones (SGC GM CSF 1～5)secreting high hGM CSF level were obtained after G418 resistance selection. The hGM CSF gene had been integrated into chromatosome of SGC by the assay of RT PCR.Results: There was hGM CSF production whose lane was about 30 kD in the culture medium of SGC GM CSF by the assay of SDS PAGE and Western blot. SGC GM CSF had the ability of the high level of GM CSF for a long time(mean 247ng/(10 6 cell?24 h).Conclusion: The hGM CSF gene transferring vector mediated by gene gun was effective and safe. These results provide a basis for study of GM CSF gene therapy for cancer.

Wnt/β-catenin signaling pathway has a close relationship with cancer and is abnormally activated in many human cancers. Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death worldwide, but the molecular mechanisms of HCC are still poorly understood. Current studies indicate that Wnt/β-catenin signaling pathway plays a key role in the development and progression of HCC. Validating the role and mechanism of Wnt/β-catenin signaling pathway in HCC will provide a theoretical basis for early diagnosis and treatment of HCC. In this review, we summarize the role of Wnt/β-catenin signaling pathway in HCC and the progress of current researches.

Objective To investigate the relationship between plasma soluble CD36 (sCD36) and nonalcoholic fatty liver disease (NAFLD) in patients combined with type 2 diabetes mellitus (T2DM). Methods Plasma levels of sCD36 were determined in normal control group (group A, n=39), patients of T2DM without NAFLD group (group B, n=39) and T2DM with NAFLD group (group C, n=59). Liver fat content (LFC) and nonalcoholic fatty liver fibrosis score (NFS) were calculated in group C. Glucose and lipid metabolic parameters, liver function parameters and inflammatory parameters were also detect?ed in all three groups. Variance analysis was applied to analyze the differences of the above parameters among three groups;Correlation analysis was used to analyze the relationship between sCD36 level and all the above parameters;Multiple step? wise regression analysis was applied to determine the influencing factors of sCD36 level in patients of group C. Results Plasma sCD36 (μg/L) levels in group B (3.87 ± 1.16) and group C (5.72 ± 1.79) are higher than that of group A (2.57 ± 0.93) (both P<0.01), and it is higher in group C than in group B (each P<0.05);Correlation analysis showed that sCD36 level was positively correlated with body mass index (BMI), waist, visceral adipose tissue,fast insulin (FINS), insulin resistance in?dex (HOMA-IR), free fatty acid (FFA), alanine transaminase (ALT), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), LFC and NFS (P<0.01 or P<0.05);Multiple stepwise regression analysis showed that FFA, LFC, TNF-αand IL-6 were in?fluencing factors of sCD36 level in patients of group C. Conclusion Plasma sCD36 level was related to fatty liver severity, liver injury and fatty liver fibrosis, it might be used as a plasma marker of T2DM combined with NAFLD. CD36 might con?tribute to the development of T2DM combined with NAFLD through inflammatory mechanisms.
