Objective To investigate the relationship between impaired glucose test and insulin resistance in pregnancy. Methods Ninety-three pregnant women who had one abnormal result among 4 of oral glucose tolerance test (OGTT) and 179 pregnant women who had normal results of OGTT from 11 hospitals of Shanghai during May 1999 to Aug 1999 were included. Insulin release test were performed at the same time. Insulin sensitive index (ISI), islet secretive function index (IFI) were calculated. Area under sugar curve (SAUC)?area under insulin curve (IAUC)?ISI? IFI?fast plasma sugar(PGO) and fast plasma insulin (INO) were compared between two groups. Results PGO, INO, SAUC, IAUC and ISI of the IGT group and control group were(5.1?1.0)mmol/L vs(4.3?0.4)mmol/L?(142?77) pmol/L vs (114?40)pmol/L?(1186?437) pmol/L vs (1058?407)pmol/L?(23?4) mmol/L vs (18?3)mmol/L and 30?20 vs 22?24 respectively, the differences were significant(P0.05). Conclusions Insulin resistance is one of the causes of impaired glucose test in pregnancy.

Ectopic internal carotid artery (ICA) is a very rare congenital variation. Unless the diagnosis is made before neck or tonsil surgery, massive hemorrhage and even death may result from injury to the vessel. Therefore, knowledge of the presence of ectopic ICAs may be important. We report two cases suffering from dysphagia associated with ectopic ICA manifesting itself as a pulsative protruding of the right lateral wall of the oropharynx.

AIM:To explore the ability of different group B streptococci ( GBS) strains on inducing platelet activation.METHODS:Six strains of GBS, separated from the septic patients with thrombocytopenia, were used as the inducers.Light transmission aggregometry was used to measure platelet aggregation.Scanning electron microscopy ( SEM) was performed to investigate the interaction of platelets with bacteria.The expression of platelet CD62P, Toll-like receptor 2 ( TLR2) and TLR4 was determined by flow cytometry and Western blotting.Furthermore, the activity of platelet TLR2 (or TLR4) was blocked by anti-TLR2 (or anti-TLR4) monoclonal antibody, and the platelet aggregation induced by GBS was detected.RESULTS:Only 3 of 6 GBS strains isolated from the septic patients induced platelet aggregation and up-regulated the expression of CD62P and TLR2 in the platelets (P<0.05), but not TLR4.Incubation with anti-TLR2 anti-body, but not anti-TLR4 antibody, significantly blocked platelet aggregation induced by GBS.CONCLUSION:Some GBS strains from the patients are able to trigger platelet activation in vitro, and platelet TLR2 may play an important role in the interaction between GBS and platelets.

Objective To establish and assess the new method of APTT assay based on the combinations of Mg2+and Ca2+for lupus anticoagulants(LA)measurements.Methods This prospective study included 309 trisodium citrate anticoagulated plasma samples from 244 random patients and 65 patients with different autoimmune diseases(AID)to establish and assess the method of LA measurement, respectively.Final concentrations of 0,2.0, 4.0, 8.0,16.0 mmol/L Mg2+were added into 25 mmol/L Ca2+solution, and Actin reagent was used to measured plasma APTT of 94 patients.The applied concentration of Mg2+-Ca2+solution was confirmed through the special and significant alteration of APTT from LA-positive and -negative plasma observed in the presence of Mg 2+(test solution).Based on Actin reagent use,the test solution and 25 mmol/L Ca2+solution were applied to measure APTT of patients and normal individuals, respectively, and the ratio of Mg2+-Ca2+-APTT to Ca2+-APTT(Mg2+-Ca2+-APTT indices)and normalized Mg2+-Ca2+-APTT indices(NAR)were calculated, respectively.Mixed plasma NAR was measured,and CV%was calculated to evaluate the repeatability and stability of Mg 2+-Ca2+-APTT method.APTT of 150 patients was measured with the test solution and Actin reagent to calculate Mg 2+-Ca2+-APTT indices, and normalized LA ratio was determined with dRVVT method.The applicability of Mg2+-Ca2+-APTT assay was assessed through comparisons of the results from the two methods.Finally, NAR and NLR of 65 patients with AID(including 26 SLE patients)were measured with Mg2+-Ca2+-APTT assay and dRVVT method, respectively, and ROC curve was also used to assess the efficacy of the two methods for LA measurements.Results In all LA-negative plasma,APTT increased from 28.1 ±4.5 s to 61.2 ±7.9 s in normal APTT group,47.2 ±8.9 s to 97.5 ±10.3 s in increased APTT group,and 27.6 ± 5.1 s to 61.2 ±7.9 s in ACA-positive group when Mg2+increased from 0 to 8 mmol/L in Mg2+-Ca2+solution(F=34.12, 38.9 and 28.35,P<0.01).Following increased Mg2+concentration, APTT shortened from 0 to 4.0 mmol/L, but simultaneously prolonged from 4.0 to 16.0 mmol/L in LA-positive plasma with prolonged or normal APTT(F=31.55 and 39.51, P<0.01), and APTT was significantly higher in 8.0 mmol/L than that in 4.0 mmol/L(P<0.001).The test concentration of Mg 2+/Ca2+solution was 4.0 mmol/L.The within, inter-day CV% of NAR was 1.39%,2.30%, and 3.44%, respectively. According to the judging criteria of <0.966 and >1.034 of Mg2+/Ca2+indices, there was 141 patients with increased indices and NLR <1.20, and 9 patients with decreased ones and NLR≥1.20 in all 150 patients.The area under ROC curve of NAR and NLR for LA detection was 0.913(95%CI:0.848-0.978) and 0.892(95%CI:0.817-0.966), respectively, and the cut-off value was 0.87 and 1.13, respectively. The sensitivity and specificity of NAR(85% and 77%)was higher than that of NLR(81% and 74%), respectively.The accordant rate of positive,negative,and total results between NAR and NLR was 94.4%, 98.5%,and 98%,respectively.Conclusion The method of APTT assay based on Mg2+combining Ca2+for LA measurements is feasible,and can be used to detect plasma LA of patients.
