Esophageal cancer is a cause of cancer mortality and accounts for the sixth most common cause of cancer-related death. The focus of recent study has shifted towards testing novel agents that target specific molecular abnormalities known to occur in esophageal squamous cell carcinoma (ESCC). The preclinical studies involving various cancer models, including ESCC, epidermal growth factor receptor (EGFR) over-expression, are linked to epithelial cell proliferation, differentiation and migration, and have an inverse relationship to tumor chemotherapy curability. Nimotuzumab is a humanized anti-EGFR monoclonal antibody that binds to the extracellular domain of the EGFR and inhibits EGF binding. In many phase Ⅱ trials, nimotuzumab showed marked antiproliferative, proapoptotic and antiangiogenic effects in tumors that overexpress EGFR. Some phaseⅢtrials are ongoing.

Objective To study the structure of spliced variants of hepatitis B virus (HBV) genomes and elucidate their potential pathogenicity. Methods Amplified the spliced variants of hepatitis B virus genomes by mean of PCR from the serum of the patients with chronic hepatitis B, sequenced and analysis the characteristics of such genomes. Results 10 different types of the spliced variants of hepatitis B virus genomes were obtained with the molecular weight ranging from 765 bp to 2039 bp. There were 6 splicing donor sites and 6 accepter sites, respectively in HBV genomes. All spliced variants showed one or more deletions in the regions coding for core, preS1, preS2 and surface protein, while retained thepathogenic X gene and cis elements which were essential for viral replication and packaging. Conclusions Spliced variants of hepatitis B virus genomes were commonly detected in the serum from chronic Hepatitis B patients, the characteristic structure of such variants implied that they might closely co-related with the pathogenicity of HBV.

Objective To compare the clinical efficacy of moxibustion Zhiyin with knee chest decubitus,ear acupoint magnetic bead press combined with knee chest decubitus and knee chest decubitus in correction of breech position,thus to provide more safe and effective correction method for the clinical treatment.Methods 150 pregnant women with breech were selected.They were randomly divided into observation group Ⅰ,observation group Ⅱ and control group according to the digital table,50 cases in each group.The control group was treated with knee chest decubitus to correct breech position,the observation group Ⅰ was given moxibustion Zhiyin combined with knee chest position,the observation group Ⅱ was given ear acupoint magnetic bead press combined with knee chest decubitus.Results The effective rates of the observation group Ⅰ and observation group Ⅱ were 96％,92％,respectively,which were higher than 76％ of the control group,the difference were statistically significant (χ2=5.09,4.18,all P＜0.05).The effective rate between the observation group Ⅰ and observation group Ⅱ showed no significant difference (P＞0.05).Conclusion Moxibustion Zhiyin combined with knee chest decubitus and ear acupoint magnetic bead press combined with knee chest decubitus in the correction of breech position have short course of treatment,high success rate,and are more economical and convenient,with high safety and good curative effect,which are worthy of promotion.

Aim To explore the effect and mechanism of resveratrol (Res) on proliferation and differentiation of murine 3T3-L1 preadipocytes.Methods 3T3-L1 preadipocytes were cultured and treated with resveratrol in different dosages.Cell proliferation was analyzed by WST-1 method. Oil red O staining method and spectrophotography were applied to analyze the degree of differentiation. Real-time PCR was applied to detect the mRNA expression of adiponectin and leptin. Western blot was applied to detect the expression of silent information regulator 1 (Sirt1),peroxisome proliferator activated receptor γ (PPARγ) and CCTTA enhancer binding proteinα (C/EBPα).Results Res inhibited proliferation of murine 3T3-L1 preadipocytes in a time-dose dependent manner.The expression levels of adiponectin and leptin mRNA were decreased, and Res also inhibited 3T3-L1 preadipocytes to differentiate into mature adipocytes. Res increased the expression levels of Sirt1 and decreased the expression levels of PPARγ and C/EBPα.Conclusions Resveratrol can inhibit the proliferation and differentiation of 3T3-L1 preadipocytes.The underlying mechanisms may include enhancing expression of Sirt1 and inhibiting expression of PPARγ,C/EBPα which are related to cell differentiation.

Hypoxiaisoneofthemostimportantfactorsinfluencingcancertherapyandclinicalprogno-sis.With positron emission tomography (PET)widely adopted in clinical practice,the development and appli-cation of PET hypoxia imaging agents has been much popular in the field currently.PET hypoxia imaging can detect tumor hypoxia region noninvasively,which has important significance for optimizing cancer treatment decisions and improving the prognosis of cancer.
