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 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.

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.

Purpose:To investigate the prevention and treatment protocol for Af after resection of esophageal and car- dia carcinoma.Methods:Analyses for clinical materials of 1527 patients underwent resection for esophageal and cardiac carcinoma.Results:There were Af 23 cases.Age older than 60 years,abnormal ECG or/and pulmonary function before operation,gastro-esophageal anastomosis above the aortic arch and histological staging Ⅲ～Ⅳ were risk factors for AF.Fa- tal AF was rarely seen.In our 23 cases after treatment in time AF disappeared.Conclusions:Further recognition for post- operative AF and management of perioperative period complication,may reduce the danger of postoperative AF.

Objective To approach the expressions and the roles of connective tissue growth factor (CTGF) and membrane type 1 matrix metalloproteinases (MT1-MMP) in valve disease with pressure overload which induces extracellular matrix remodeling of left ventricle. MethodsOf 32 patients, 16 cases were pressure overload group (PO), who had the multiple valve disease with predominately aortic valve stenosis, having a ring diameter of aorta valve less than 1.3 cm, cross valve pressure gradient equal or more than 40 mmHg, and valvular regurgitation less than 4.0 cm2; The other 16 cases, as mitral stenosis group (MS), were simple mitral stenosis patients with single valve replacement. Meanwhile, 5 normal individuals served as control, who died from accident. Echocardiography was used to analyze the left ventricular function and detect the hypertrophic level of the left ventricle. Left ventricle muscle samples were obtained during operation. Histological features were studied by Masson staining, and collagenous contents were quantitated with a computer-assisted imaging analysis system. The mRNA expressions of CTGF and MT1-MMP were detected with RT-PCR. ResultsConcentric hypertrophy was observed significant in PO group, but myocardial hypertrophy was not found in MS group. Compare to the MS group and control, PO group had significantly more collagenous contents in left ventricle, thickened vessel wall, and narrow lumen of blood vessel (P0.05), but CTGF mRNA expression was increased in MS group compare to control (P
