Objective To study the growth inhibision effect of disodium cantharidinate and Vitamin B6 injection on hepatocellular carcinoma cell line HepG2.Methods Different concentrations of disodium cantharidinate and Vitamin B6 injection were applied on the hepatocellular carcinoma cell line HepG2.The inhibition rate of HepG2 growth was measured by MTT assay.The apoptotic rate was detected with flow cytometry,and the morphology of apoptosis was observed by fluorescence microscope.Results The growth of HepG2 cells was significantly inhibited as well as the apoptosis of HepG2 cells was significantly encouraged by disodium cantharidinate and Vitamin B6 injection(P

Objective To investigate the expression and clinicopathological significance of CXCR4 and HIF-1α protein in esophageal squamous cell carcinoma tissue and explore their correlation.Methods The expression of CXCR4 and HIF-1α protein were assessed by immunohistochemistry SP method in 56 cases with esophageal squamous cell carcinoma and in 20 cases with surrounded normal tissue.Results The expressions of CXCR4 and HIF-lα in esophageal squamous cell carcinoma were significantly higher than those in normal tissues[62.50 ％ (35/56) vs 10.00 ％ (2/20); 57.14 ％ (32/56) vs 0(0/20)](x2=16.259,19.740,P ＜0.01).The expression of CXCR4 and HIF-1α were both correlated with invasion depth (x2 =4.736,7.665,P ＜0.05) and lymph node metastasis ( x2 =7.207,6.389,P ＜0.05),and had no correlation with cancer cell differentiation.The expressions of CXCR4 and HIF-lα in esophageal squamous cell carcinoma were positively correlated (r =0.298,P ＜0.05).Conclusion CXCR4 and HIF-1α are highly expressed in esophageal squamous cell carcinoma.The two have a close relation to esophageal squamous cell carcinoma growth,invasion and metastasis.

An analysis of the fundamental concepts for public hospital reform further defined public hospitals and other hospitals,business and non-business in nature,public benefits and welfare,as well as public benefits and profit-oriented hospitals.These distinctions can help reformers of public hospitals clarify their concepts,make clear the purpose and direction of the public hospitals reform,so as to speed up the reform with theory support.

This paper studied the development stages in terms of the public nature of public hospitals in China and analyzed the causes for their weakened public benefits.It proposed the principle of government guidance,achieving government purchasing of healthcare services as the roadmap,as well as building and improving the service purchasing system,performance appraisal system,and payment review system along with supervision system.These measures are designed to make public hospitals in their public benefit nature with scientific system design,powerful institutional guarantee,and efficient execution strategies.

Purpose To Prepare anti- HIV-1 gp120 monoclonal antibodies and to identify the specificity of antibodies in order to provide technique for preparing HIV remedial antibodies. Methods The gene fragment of HIV-1 gp120 was connected to PEGX-4T-2 prokaryotic expressing vector. The vector was cut by enzyme. GST-HIV protein was expressed by E. coli XL1-blue. The BALB/c mice were immunized with purified GST-HIV antigen, and then the fusion of mice spleen cell and myeloma cell SP2/0 was executed as the routine cell-fusion technique. Positive cells were screened by Indirect ELISA. Immuno-blotting assay and Western blot identified the specificity of antibodies. Results External gene section from the recombinant plasmid by sequencing showed the same size of HIV-1 gp120 gene sequences. An external expressed protein band of 32 KD was obtained after purified protein SDS-PAGE electrophoresis. It indicated that six strains of hybridoma cells secreting special monoclone antibodies had been obtained. ELISA results showed that six strains monoclonal antibodies only reacted to HIV-1 gp120 antigen. Western blot results showed that a band with molecular weight 32 kDa was obtained, which could interact with HIV-1 gp120 monoclonal antibody. Conclusion Six strains of hybridoma cells secreting special monoclone antibodies had been obtained. The prepared monoclonal antibodies have established a basis for HIV remedial antibody.

Objective To investigate the changes and clinical significances of the chemokines of interferon-?-inducible protein-10(IP-10),monocyte chemoattractant protein-1(MCP-1) and growth-related oncogene-?(Gro-?) involved in pathagenesis of Kawasaki disease(KD) and HenochSchonlein purpura(HSP).Methods The chemokines production of IP-10,MCP-1 and Gro-? were assayed by ELISA in 15 patients with KD,12 patients with HSP and 10 healthy children.Results The plasma levels of IP-10 and MCP-1 were markedly elevated in KD group [(394.2?176.4)and(420.5?163.4)ng?L-1]compared with HSP group[(94.8?66.4)and(109.2?76.6)ng?L-1] and the control group [(76.4?46.5)and(87.7?47.8)ng?L-1](all P0.05),as well as Gro-? between the three groups.Conclusion Monocyte may enhance the immune damage in KD pathogenesis,and the levels of IP-10,MCP-1 may be important indexes for KD.Neutrophil may be not involved in pathogenesis of HSP and KD.

【Objective】 To investigate the effect of Kaixin Capsule (KC) on gene expression of myocardial immune inflammatory factor in dogs after resuscitation and to search for an effective way to counteract the progress of systemic inflammatory response syndrome (SIRS) after cardiopulmonary resuscitation. 【Methods】 Fifteen hybrid dogs were randomly divided into three groups, 5 dogs each: pseudo-operation group (group A), model group (group B) and KC group (group C). The dog model of cardiac arrest and resuscitation was established; the dogs were executed and the heart was isolated 180 min after the recovery of autonomic circulation. Myocardial total RNA was extracted and the mRNA expression of objective gene was detected by reverse transcription polymerase chain reaction (RT-PCR). 【Results】 mRNA expression of Toll-like receptor (TLR_4) and tumor necrosis factor ?(TNF-?) in group B differed from that ingroup A (P
