Objective To observe inhibiting effect of endostatin on subcutaneous transplant tumor of breast carcinoma, and to illuminate the therapeutic effect of endostatin in the cancer. Methods The effect of en-dostatin on MCF-7 cell proliferation was studied by MTr. The model of MCF-7 cell transplant tumor on nude mice was constructed. Endostatin was injected intradermally around the transplant tumor. Inhibition effect on the tumor was observed. Results Endostatin with the concentration of 10 μ/mL and 15 μg/mL can inhibitMCF-7 cell proliferation effectively (P < 0. 05 ). After endostatin injection, tumor weight, volume and mi-crovessel density decreased significantly(P < 0.05 ). Conclusion Endostatin can inhibit breast carcinoma proliferation through inhibiting angiogenesis and the tumor cell itself.

OBJECTIVERecently studies showed infections of Chlamydia pneumoniae (Cp), Helicobacter pylori (Hp) and cytomegalovirus (CMV) played roles in the development of atherosclerosis. The aim of this study was to study relationship between infection of Cp, Hp and CMV, systemic inflammation and coronary artery disease (CAD).
METHODSFourty-five patients with at least one coronary artery stenosis > 50% and 33 control subjects with negative coronary angiography were recruited for this case-control study from May 2000 to October 2001. Antibodies against Cp, Hp and CMV were measured and serum C-reactive protein (CRP) levels determined for each case. CRP level > 0.8 mg/dl was defined at elevated CRP level.
RESULTSThe prevalence of Cp IgG, Hp IgG or Hp IgA antibody was associated with CAD (P = 0.017, P < 0.001, P = 0.009). After adjustment for age, gender, smoking, hypertension, hyperlipidemia and diabetes, the association was still seen. Mean CRP value was significantly higher in patients with CAD, compared to those without CAD (P < 0.001). Multivariate analysis showed statistical significance (P = 0.03). Elevated levels of CRP were found to be an important parameter for CAD (P = 0.032). The prevalence of Cp IgG antibody, Hp IgG and CMV IgG antibody all showed no association with elevated levels of CRP (P = 0.391, P = 0.253, P = 0.724). The ratio of elevated levels of serum basic CRP in the group with IgG antibodies to 3 pathogens was 32.1% while in the group with IgG antibodies to CONCLUSIONSTwo chronic infections, Cp and Hp, might increase the risk of CAD. There was no association of CMV infection with CAD. C-reactive protein was an independent parameter of CAD, but the increased systemic inflammation in CAD did not seem to be related to aforesaid infection.

Objective To investigate the antitumor effect of the recombined adeno-associated virus encoding caveolin-1 regulated by progression-elevated gene (PEG) promotor on the angiogenesis of implanted human hepatocellular carcinoma(HCC) cell lines in a nude mouse model. Methods HepG2 cells were inoculated subcutaneously into NOD/SCID mice, and animals were treated with rAAV-PEG-caveolin-1 after tumor cell innoculation. The fluorescence ratio of Evans blue to FITC-dextran was used to assess the changes of microvasculature permeability of the tumor. Western blot and immunohistochemical analyses were employed to detect PECAM-1 expression in tumor microvascular endothelium and microvessel density(MVD), respectively; NOS activity was assessed by citrulline generation. Tumor growth was observed and tumor cell apoptosis in tumor tissues were measured by TUNEL. Results Tumor growth was significantly inhibited in mice injected with rAAV-PEG-caveolin-1. The administration of rAAV-PEG-caveolin-1 significantly blocked vascular leakage in the tumor microcirculation. The levels of PECAM-1 protein detected by Western blot were markedly reduced in rAAV-PEG-caveolin-1-treated mice, and there were fewer MVD in tumors from caveolin-1-treated mice, while NOS catalytic activity was much lower in rAAV-PEG-caveolin-1-treated mice compared to the control and empty vector-treated animals. TUNEL demonstrated significant induction of tumor cell specific apoptosis. Conclusions rAAV-PEG-caveolin-1 can reduce tumor progression through blocking microvascular formation by inhibiting eNOS.

Objective To study the role of hematopoietic growth factor(HGF)of placenta chorionic villus in fetal hematopoiesis during embryo ontogeny by observation of the appearance time and the content changes with the fetal growth, which was compared with HGF in cord blood. Methods Thirty embryo villus (2 g each) and 30 cord blood (2 mL each) were collected separately from early pregnant stage(6- 8 weeks), middle pregnant stage(16-22 weeks)and late pregnant stage (37-42 weeks). The levels of HGF were detected by enzyme - linked immunosorbent assay. Results HGF were produced on the early pregnant stage and the content of FL-T3,IL-3 increased gradually.There were significantly differences at different stages(P

Objective To study the prevalence of fatty liver and its risk factors in adult population of Pudong New District,Shanghai detected by combination of B-type uhrasonographic features and elevated serum activity of alanine aminotransferase (ALT).Methods A cross-sectional survey was performed in 2017 residents aged 16 years over recruited from four neighborhoods of Prdong New District of Shanghai with multi-phase cluster sampling,including interview with questionnaire,physical check-up,anthropometry, measurement of plasma glucose and lipid profile,ALT activity and real-time B-type ultrasnnography.Serum hepatitis B surface antigen (HBsAg) was further detected for those with elevated ALT activity.Results Prevalence of fatty liver was 21.32 percent (430/2017) in the residents of the District participated in this survey.Prevalence of abdominal obesity,hypertriglyceridemia,hyperlipoproteinemia (low-density lipoprotein-cholecterol),essential hypertension,impaired glucose tolerance,diabetes and metabolic syndrome were 71.16,71.16,11.86,66.74,35.58,24.40 and 47.21 percent in those with fatty liver, respectively,as compared to 26.34,12.73,4.79,39.57,24.01,6.81 and 11.28 percent in those without fatty liver (controls),respectively.Multivariate logistic regression analysis showed that body mass index, 2-h postprandial glucose level,diastolic blood pressure,serum level of triglyceride,abdominal obesity and diabetes all were independent risk factor for tatty liver,with odds ratio (OR) of 1.080,1.149,1.035, 1.526,1.960 and 1.391,respectively.Conclusions Prevalence of fatty liver was relatively high in Shanghai Pudong New District.Fatty liver closely associates with disturbance of carbohydrate and lipid metabolism.

Objective To study the effect of Rho-kinase inhibitor on experimental allergic neuritis. Methods 54 female Lewis rats were divided into three groups; EAN group, EAN + Rho-kinase inhibitor group, and CFA group. The rats were sacrificed on the 9th day, 17th day, and 26th day after immunized. The changes of weight, EAN incidence, and mean day of onset, mean maximum clinical score, and histopa-thology were observed. Results The clinical course in EAN group reached peak on the 17th day. Compared with EAN group, the weights of Rho - kinase inhibitor group were increased, while EAN incidence, mean day of onset delay, and the clinical scores in Rho-kinase inhibitor group were significantly decreased, ( P < 0.01) , and the demyelization and inflammation cells infiltrating was ameliorated in spinal nerve. CFA group didnt show any clinical manifestation. Conclusions Rho - kinase inhibitor may ameliorate the development of EAN through inhabiting the Rho/ROK signal pathway.
