Although the relationship between tumor and venous thromboembolism has been demonstrated, the clinical implications of this association still have to be thoroughly elucidated. The aim of this paper is to review the pathogenetic mechanisms accounting for the development of venous thrombosis, the relationship between tumor and venous thromboembolism, the prophylaxis and treatment of venous thrombosis in tumor patients.

Objective To analyze the oral glucose tolerance test (OGTT) curve characteristics in Chinese women with gestational diabetes mellitus (GDM) or gestational impaired glucose test (GIGT) and to evaluate whether omission of the third-hour plasma glucose measurement of the OGTT could alter the sensitivity of the diagnosis on GDM,and whether there is a close relationship between plasma glucose values of 50 g glucose challenge test (50 g GCT) or OGTT and insulin therapy. Methods A retrospective analysis on medical records of 647 cases with GDM from January 1,1989 to December 31,2002 and 233 cases with GIGT were performed. Among 647 cases of GDM,535 were diagnosed by 75g OGTT. All OGTT (535 with GDM and 233 with GIGT) results were evaluated. Results There were 112 cases of GDM diagnosed by elevated fasting plasma glucose without OGTT performed. Of 535 cases of GDM diagnosed by OGTT,49.2% (263/535) women were with fasting plasma glucose value ≥5.8 mmol/L;90.1% (482/535) women with 1hr plasma glucose values ≥ 10. 6 mmol/L;64.7% (359/535) were with 2 hr plasma glucose levels ≥9.2 mmol/L. There were only 114 cases (21.3%) with abnormal 3 hr plasma glucose levels among 535 women with OGTT,and when 3 hr plasma glucose reached cutoff value,49.1% the other three values of OGTT were abnormal and 34.2% with the other two values of OGTT. Among 233 women with GIGT,only 4 cases with the abnormal 3 hr plasma glucose. We also investigate use of the glucose values for the first 2 hours of OGTT only missed 19 cases of GDM,still discriminated 516 cases. Omission of the third -hour glucose tolerance test value only resulted in failure to diagnose 2.9%(19/647) of GDM cases and 1.72%(4/233) of GIGT cases in Chinese women. Plasma glucose levels ≥11.2 mmol/L following 50 GCT were highly associated with GDM necessitating insulin therapy (75.4%). An elevated fasting plasma glucose level was also associated with insulin therapy (59.7%).Conclusion Omission of the third -hour glucose tolerance test value still yielded a higher sensitivity of 97.1%(628/647) of GDM cases and 98.2%(229/233) of GIGT cases in Chinese women. It is practicable to omit 3-hour post -glucose ingestion value of the OGTT in Chinese women. Plasma glucose levels ≥11.2mmol/L following 50g GCT indicated 75.4% cases of GDM necessitating insulin therapy.

Objective To determine the collagen deposition in adventitia of venous wall and the influence of removal venous thrombus by Fogarty balloon catheter on venous wall at different time.Methods The collagen deposition in adventitia of venous wall in inferior vena caval thrombosis in rats, and the injury of venous wall caused by Fogarty balloon catheter removal of thrombus at different time were observed. Results Collagen deposition in adventitia of venous wall increased with time. The peak of collagen deposition was 10 days after thrombus formation, which was significantly different from the control group (P

ObjectiveTo study the effect of Rehabilitative Ankle-Foot Orthoses training program on walking function of hemiplegic patients after stroke .Methods95 patients were randomly divided into two groups: observed group (49 cases) and control group (46 cases). The patients of control group were trained by routine rehabilitation training program, the patients of observed group were trained by Rehabilitative Ankle-Foot Orthoses and routine rehabilitation training program.ResultsAfter training, either observed group or control group showed significant improvement at walking function and ADL(P<0.01), but the improvement on observed group were more marked than coutrol group(P<0.01 and P<0.05). ConclusionsThe ability of walking in acute stroke patients were obviously improved, and the degree of the disability of them was decreased by Rehabilitative Ankle-Foot Orthoses.

Objective To detect antibodies against human papilloma virus-47 E2m345-362 peptide whichis homologous to profilaggri306324 peptide and anti-citrullinated human papilloma virus-47 E2345-362 peptide antibodies in rheumatoid arthritis(RA)and to investigate its role in the pathogenesis of RA.Methods Serum samples were obtained from 119 patients with RA, other rheumatic diseases and healthy individuals.We searched the homologus sequence of profilaggrin306-324peptide by using NCBI (the National Center for Bioteehnology Information)BLAST (basic local alignment search tool),and synthesized human papilloma virus-47 E2345-362 peptide which was highly homologous to profilaggrin306-324 peptide and the citrullinated Human papilloma virus-47 E2345-362 peptide.The presence of antibodies against E2345-362 peptide and citrullinated E2345-362 peptide was examined by enzyme-linked immunosorbent assay(ELISA).The associations between these antibodies and the clinical features of RA were evaluated.Results ①(41.2%)and titer (AU was 105.7)of anti citrullinated E2345-362 peptide antibodies in RA were significantly higher than those of patients with other rheumatic diseases and healthy individuals.However,the prevalence of anti-E2345-362 peptide antibodies in RA patients was similar to that of patients with other rheumatic diseases and healthy individuals(P>0.05).②The samples that were pre-incubated with cyclic citrullinated peptide (CCP) had lower titer of anti-citrulllinated E2345-362 peptide antibodies.③The titers of anti-CCP antibodies and anti-PAD14 antibodies in anti-citrullinated E2345-362 positive patients were higher than those of anti-citrullinated E2345-362 negtive patients.It showed significant correlations between anti-citrulllinated E2345-362 peptide antibodies and anti-PAD14 antibodies(r=0.485,P<0.01).④ DAS28 score,ESR,X-ray stages,AKA in anti-citrullinated E2345-362 positive patients were higher than those of anti-citrullinated E2345-362 negative patients.Conclusion The presence of anti-citrullinated E2345-362 peptide antibodies in RA indicates that HPV-47 E2 may act as an auto-antigen which may play an important role in the pathogenesis of RA.The increasing of PAD14 may make it easy for HPV-47 E2 to be citrullinated and may induce the subsequent auto-immune reactions.

Objective To investigate the effect of mycophenolic acid on the proliferation of smooth muscle cells (SMCs) in rats' pulmonary arterial at cellular level. Methods Growth curve, MTT tests, and flow cytometry were used to detect the number of proliferative cells, the A-value of living cells and the DNA content of the control and drugs groups respectively and the number of cells in G1-phase, S-phase, G2M- phase and the proliferation index were calculated. Results Compared with the control group, the number of living cells in the mycopbenolic acid groups (with the concentration of 1, 10, 100 μmol/L) decreased, except the lowest dosage group (100 nmol/L). The difference was statistically significant (P<0.01). The living cells measured by MTT dose-dependently reduced in the mycophenolic acid groups. In the mycophenolic acid groups, the fraction of living cells in the S-phase and G2M-phase decreased respectively while that in G1- phase increased, and the proliferation index decreased. All these responses presented with a dose-dependent manner. Conclusion Mycophenolic acid can effectively inhibit the proliferation of rats' pulmonary arterial SMCs. This process happens mainly in ONA synthesis phase, and is dose dependent. In addition, these effective concentrations are all in the available range for clinical application.

Objective To analyze the relationship between autoimmune thyroid disease(AITD) and the genetic, immune and environmental factors. Methods A total of 500 patients with AITD and 206 healthy persons were included in this study. After carefully collecting the patient history and medical records, the inquiry forms were fulfilled to know about the genetic, immune and environmental factors. Statistical analysis was conducted using the SPSS statistical system. Results It was shown that family history of AITD, smoking and psychological factors were significantly different between AITD group and control(P0.05). Meanwhile, the difference of infection, contact with chemical poison, intake of sea food, miscarriage and blood type were also not significant between the patients and controls. Conclusion It is suggested that the heredity plays an important role in the pathogenesis of AITD. Smoking and psychological factors also have evident influence.
