Objective To determine 1 hour plasma glucose cutoff value during OGTT to screen diabetes and IGR and its relationship with islet β cell function and insulin sensitivity. Methods 4731 subjects were recruited to perform an OGTT.The cutoff value of 1h-plasma glucose during OGTT was analyzed by receiver operating characteristic curve (ROC curve).And according to the two cutoff values,we classified all the subjects to three groups,and compared HOMA-IR,HOMA-β,insulinogenic index and shape index among groups,then analyzed its correlation with each parameter. Results According to ROC results, to diagnose type 2 diabetes mellitus,the optimal cutoff value of 1h plasma glucose during OGTT was 12.935mmol/L,with sensitivity of 81.52%,specificity of 86.94%. To diagnose impaired glucose regulation(IGR),the optimal cutoff value of 1h plasma glucose was 9.815mmol/L,with sensitivity of 74.96% and specificity of 77.86%. We classified all the subjects to three groups, and among the three groups the insulinogenic index, shape index, HOMA-IR, HOMA-β showed statistically significant difference (all P＜0.01). There was a negative correlation of OGTT-1hPG with insulinogenic index and HOMA-β(all P＜0.01) and a positive correlation of OGTT-1h PG with shape index and HOMA-IR (all P＜0.01). Conclusions To diagnose type 2 diabetes mellitus,the optimal cutoff value of 1h plasma glucose during OGTT is 12.935mmol/L.To diagnose impaired glucose regulation(IGR),the optimal cutoff value of 1h plasma glucose is 9.815mmol/L.And 1h PG can reflect the islet β-cell function and insulin resistance.

Breast cancer is by far the most common cancer for females.The recent researches focus on early diagnosis,optimal adjuvant therapy and curative effect surveillance.The paper summarizes the application of tissue and fluid tumor markers in the diagnosis,treatment,curative effect surveillance and prognostic prediction of breast cancer,which include widely-accepted estrogen receptors,HER2-neu and CA15-3,and novel ones such as Cyclin E,TIMP-1,RAR-?,hK10 and BRCA-1.

Objective To investigate the depression status among the elderly living alone in a community of Shanghai and to analyze the influencing factors.

Objective To evaluate the pathophysiology of paraplegia during transarterial chemoembolization in liver cancer and investigate effective management and prevention for improving clinical situation and relieve major symptoms.Method 2758 patients accepted TACE procedure because of liver cancer(and/or combined with remote metastasis),demonstrated 4 cases suffering from paraplegia(3 males,1 female)since Mar.2003 to Feb.2005,with mean age of(51?14)years old,The operative records and the clinical features after chemoembolization were summarized in detail.Results The incidence of paraplegia was 0.145%,with major symptoms of dysesthesia and hypokinesise emerging within 4 hours after TACE,and most symptoms aggravating gradually within 24-48 hours untill paraplegia appeared,and then turned to stabilization about 5-7 days,with their body functions partial recovery in 2 months.Conclusion More attention should be paied to prevent ectopic embolization of spinal cord vessels originating from extrahepatic collateral arteries during TACE or TAE.

Objective:To probe distribution law and pathogenesis of TCM complex symptoms of functional dyspepsia and irritable bowel syndrome.Methods:Generally recognized criteria was to establish database of comprehensive analysis of the data gained by the four methods of diagnosis,and analyze with SPSS8.0.Results:Syndrome distribution was most closely related with spleen deficiency,accounting for 66.7%;and the next,with stagnation of liver-Qi,accounting for 40.3%;the last,with the kidney,only accounting for 5.6%.Conclusion:Cause of disease and inducing factors of this disease are closely correlated with pathogenic cold, diet of lipids,mental depression,prolonged disease,wound due to abdominal operation.The disease is located at the stomach, intestine with most coexistence of deficiency and excess,and spleen deficiency is the key of pathogenesis.

Objective To study the clinical features of diagnosis and treatment in children with low-risk myelodysplastic syndrome(MDS) and improve the diagnosis and treatment.Methods The examinations of 17 children with low-risk MDS were analyzed.The blood concentrations of cyclosporine,one of the therapeutic drugs,were monitored and the responses to the treatments were evaluated.Results Exa-mination of full blood count showed that the reductions of 3 cell types,2 cell types and 1 cell type were 11 (64.7%)cases,5(29.4%)cases and 1(5.9%)case,respectively.Reticulocyte count showed an increase in 82.4% of the patients and normal in 3 cases.Fourteen in 17 cases were hyperplastic marrow and 3 cases were hypoplastic marrow.Among all cases,one lineage,2 lineages and 3 lineages dyspoiesis were seen in 8(47.1%),7(41.2%) and 1 (5.9%)cases,respectively.One case showed no dyspoiesis.Cytogenetics examination showed normal in 10(58.8%) cases and abnormal in 7(41.2%) cases.Fifteen (88.2%) cases had normal proportions of CD59 negative cells,while 2 cases had higher proportions.The blood concentrations of cyclosporine that were tested in 9 cases at the end of the third week were in a range of 95.3-316.5 ?g/L.The therapeutic effect of 10 cases were evaluated at the end of the third month after being treated.Eight cases achieved haematological improvement and 2 cases didn′t.The rate of improvement was 80%.Conclusions The patients of low-risk MDS are mostly school-aged children and pancytopenia is the most common sign.The combination of predisone,cyclosporine and stanozolol agents shows good effect to treat low-risk MDS.The absorption of cyclosporine is different individually,so it is significant to adjust the dosage of cyclosporine according to the concentration regularly in clinical practice.

Objective To investigate the relationship among methotrexate(MTX) plasma concentration,dosage,clinical effecicy and toxicity, and to evaluate it′s clinical significance.Methods MTX was measured by a flurorescence polarization immunoassay in plasma samples obtained from acute lymphoblastic leukemia(ALL) patients treated in different doses of MTX, and these results were analyzed combined with clinical manifestations.Results 1.The average of plasma concentration at 24 hours increased with the increasing doses of MTX. The relapse rate decreased with increased plasma concentration;2.The cerebrospinal fluid(CSF) concentrations prior to the intrathecal MTXinstillation were all below the effective concentration, so the intrathecal MTX instillation was needed;3.No severe toxicity was observed in the study, because the plasma concentration was below the high risk.Conclusion The study of MTX plasma concentration provides us an objective basis for the individualized chemotherapy.

Objective To analyze prognostic factors in children with acute myeloid leukemia(AML).Methods Retrospective analyze the relationship between many factors of the diagnosed children with AML and their 3-years event-free survival(EFS).Statistics was analyzed with ?2 test.Results The 3-years EFS was 47.5%.According to the analysis of statistics,EFS of some children groups had statistical differences with their controls (P

0.1).One(1.3%) of them suffered from intracranial hemorrhage.Conclusions 1.(L-ASP) may affect the function of coagulation system,such as prolonged APTT and hypofibrinogenemia.2.There was no statistical difference in side effects of coagulation,in use of domestic L-ASP and foreign L-ASP,intravenous dosing and intramuscular dosing.
