Antiangiogenesis therapy is one of the most common anticancer therapies. Bevacizumab is a monoclonal antibody that blocks the binding of the vascular endothelial growth factor to its high-affinity receptors. It is the only antiangiogenic agent approved for the first-line treatment of advanced non-small cell lung cancer (NSCLC). Many recent studies have attempted to determine the suit-able partners of bevacizumab in first-line treatment of NSCLC and evaluate its efficacy and safety as a second-line or beyond and con-tinuous treatment of beyond disease progression in patients with advanced NSCLC. This review summarizes current clinical research about the efficacy and safety of bevacizumab in the treatment of advanced NSCLC.

Objective:To observe the curative effect of vinpocetine combined with Danhong injections in the treatment of posterior circulation ischemia syndrome. Methods:Totally 120 patients with posterior circulation ischemia syndrome were selected and randomly divided into the treatment group and the control group with 60 cases in each. Both groups were treated by the conventional therapy, meanwhile, the treatment group was given vinpocetine and Danhong injections, and the control group was given vinpocetine alone. The treatment course was 14 days. The curative effect was observed, blood rheology and hemodynamics were also studied. Results:The to-tal effective rate of the treatment group was 95. 0%, which was significantly higher than that of the control group (75. 0%) with statis-tically significant difference(P<0. 05). After the treatment, the blood rheology (viscosity, low shear viscosity, plasma viscosity and reduced viscosity) and TCD ( LVA, RVA, BA and PI) in the two groups were significantly improved, and the treatment group showed more significant improvement(P<0. 05). Conclusion:Vinpocetine combined with Danhong injections in the treatment of posterior cir-culation ischemia syndrome has significant effect in the effective improvement of blood rheology and hemodynamics, which is worthy of clinical promotion and application.

OBJECTIVE:To systematically review the efficacy and safety of mizolastine combined with H2 recepter antagonists in the treatment of chronic urticaria,and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from PubMed,Cochrane Library,EMBase,CBM,CJFD,etc.,randomized controlled trials (RCT) or QRCT about mizolastine com-bined with H2 recepter antagonists(test group)versus mizolastine alone(control group)in the treatment of chronic urticaria. After quality evaluation and data extract,Meta-analysis was conducted by using Stata 12.0 statistics software. RESULTS:A total of 12 RCT were included,involving 1 188 patients. Results of Meta-analysis showed the effective rate [RR=1.23,95%CI(1.16,1.31), P<0.001] in test group was significantly higher than control group,subgroup analysis showed the the efficacies of different combi-nation of mizolastine and other drugs were significantly better than control group;there was no significant difference in the inci-dence of adverse reactions between 2 group[RR=1.01,95%CI(0.71,1.44),P>0.05]. CONCLUSIONS:The effective rate of mizo-lastine combined with H2 recepter antagonists is significantly higher than mizolastine in the treatment of chronic urticaria,with bet-ter safety. Due to the limit of methodological quality and sample size,it remains to be further verified with more rigorously de-signed and long-term follow-up of large-scale RCT.

Aim To investigate the effects of cajanonic acid A (CAA) on lipid metabolism in murine 3T3-L1 adipocytes. Methods 3T3-L1 cells induced to differ-entiated into mature adipocytes were treated with CAA in different dosages for 48 h, then total lipids as well as triglyceride, free fatty acid and glycerol were meas-ured. The expression levels of genes related to lipid metabolism were quantitatively analyzed by real-time fluorescent quantitative polymearase chain reaction ( RTFQ-PCR) . Results Total lipids and triglyceride in 3T3-L1 adipocytes were markedly reduced by CAA. The release of free fatty acid and glycerol was lower than that of control. This coincided with decreased mRNA levels of the key enzymes involved in de novo lipogenesis ( acetyl CoA carboxylase and fatty acid syn-thase) , fatty acid uptake ( lipoprotein lipase) , and li-polysis ( hormone sensitive lipase and adipose triglycer-ide lipase ) . While the expression of fatty acid oxida-tive genes including acyl CoA oxidase and carnitine palmitoyl transferase1 was increased after CAA treat-ment. Conclusion CAA may inhibit lipogenesis and lipolysis,reduce circulating free fatty acid and improve the lipid metabolism in adipocytes by regulating gene expressions.

Objective To study the expression and clinical significance of miR-183-5p, TβRⅠ and TβRⅡ in esophageal squamous cell carcinoma (ESCC). Methods The mRNA and protein expression of miR-183-5p, TβRⅠ and TβRⅡ were examined in ESCC cell lines ECA-109, TE-1, normal esophageal epithelial cells, tumor tissues and tumor-free tissues from 72 ESCC patients. Their clinical significance and the relationship between miR-183-5p and the latter two were analyzed. The effects of miR-183-5p on the expression of TβRⅠand TβRⅡ in ECA-109 cells and the cell functions of ECA-109 were also investigated. Results Compared with the normal esophageal epithelia cells, ESCC cell lines TE-1 and ECA-109 were statistically characterized by a high expression of miR-183-5p (all P<0.05) and low expression of TβRⅠand TβRⅡ(all P<0.05). The expression of miR-183-5p in ESCC tissues was higher than that in adjacent normal tissues, while the expressions of TβRⅠ and TβRⅡ were lower (all P< 0.05). The expression of miR-183-5p was closely related to sex, tumor differentiation, tumor staging, distant metastasis, lymphatic metastasis, and tumor location (all P<0.05). TβRⅠlevel was associated with sex, lymph node metastasis and tumor size (all P<0.05). Experimental data showed the negative correlation between the expression of miR-183-5p and TβRⅠin ESCC tissues (r= -0.521, P< 0.05). Over expression of miR-183-5p significantly inhibited the expression of TβRⅠ in ECA-109 cells (P< 0.05) and promoted the growth, invasion and metastasis of ECA-109 cells (P< 0.05). Low expression of miR-183-5p significantly promoted the expression of TβRⅠ in ECA-109 cells (P< 0.05), and suppressed the growth, invasion and metastasis of ECA-109 cells (P< 0.05). There was no significant change in the expression of TβRⅡ in the transfection experiments. Conclusion MiR-183-5p is closely related to the abnormal expression of TβRⅠ, which may exert an important role in the progression of lymphatic metastasis.

Background and purpose:Hepatocellular carcinoma (HCC) is a common malignant tumor of the digestive system in our country, with high fatality, development of HCC and the machine system research and treatment is a primary issue in current study of HCC. To explore the expression ofβ-catenin at different stages in the process of hepatocellular carcinoma carcinogenisis for SD rats induced by chemicals. Methods: The experimental group included 48 male SD rats mice with primary liver cancer induced by diethylnirtosamine/carbon tetrachloride/Ethanol, while 48 normal male SD rats mice were used as the control group. The rats were killed every 3 weeks to collect the specimens and observe the pathological changes by HE staining. The changes ofβ-catenin protein expressions were detected by immunohistochemistry and Western blot respectively. Results:SD rats liver cancer was conifrmed by HE staining after 21 weeks DEN/CCl4/Ethanol induction. Immunohistochemistry showed thatβ-catenin expression level was obviously higher in the experimental group(0.27±0.01) than that of the control group(0.21±0.02) after 3 weeks induction(P<0.05). As time progresses, the expression levels ofβ-catenin kept on rising, and at the 18th(0.30±0.02) and 21th weeks(0.32±0.02), it was significantly higher than that of the earlier liver tissues of the experimental group(P<0.05), Western blot consistent with immunohistochemical results. Conclusion:β-catenin protein expression is different in the normal liver tissue, cirrhosis, liver cancer,β-catenin and the occurrence of liver carcinoma development had close relationship.β-catenin protein in the cell with further accumulation, may active a series of target gene, leading to the formation of liver cancer..
