Objective:To compare the difference of microalbuminuria (MAU) and von Willebrand factor (vWF) between essential hypertensives and hypertensive patients with metabolic syndrome (MS), and to explore the association of these factors with MS. Methods: According to the new definition of MS by International Diabetes Federation (IDF) for 2005, 133 consecutive essential hypertensives were divi-ded into two groups: hypertensive patients with metabolic syndrome (EH-MS group, n=97), and essential hypertensives (EH group, n=36). Biochemistry assay, plasma vWF, 24 hours urine albumin excretion (UAE) and morning urine albumin/creatinine ratio (ACR) were measured. The association of MAU and vWF with MS was analysed. Results: Waist circumference, body mass index, triglyceride (TG), low density lipoprotein cholesterol (LDL-C), plasma vWF and UAE were increased(P0.05, respectively). Logistic regression showed HDL-C, TG, LDL-C,vWF and UAE were associated with the deve-lopment of MS in hypertensive patients (standardized coefficients: -0.825, 0.63, 0.339, 0.331, 0.371,P

Objective To establish the rat overlap syndrome (OS) model of intermittent hypoxia (IH) combined with pulmonary emphysema and to explore its connection with hepatic oxidative stress, inflammatory status in the live and coagu?lation profile. Methods Male Wistar rats (n=60) were randomly divided into four groups:control group (A), IH group (B), pulmonary emphysema group (C) and OS group (D). The rat model of pulmonary emphysema was established by exposing rats in smoke for 16 weeks. From the 13th week, pre-programmed intermittent hypoxia/re-oxygenation (IH/ROX) exposure was given in the meantime of smoke exposure in OS group. Liver tissues were sectioned or triturated for pathological scoring or for detecting expression levels of superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) respectively. Se?rum levels of coagulant/anticoagulant factors such as antithrombin (AT), fibrinogen (FIB), von Willebrand factor(vWF) and FactorⅧ(FⅧ) were also evaluated using biochemistry analysis. Results The levels of pathological scores and coagulant factors(FIB, FⅧ:C and vWF:Ag)were significantly higher in group D than those in group A, B and C. The values of SOD, CAT and AT were significantly lower in group D than those in other three groups. Serum levels of FIB, vWF:Ag, FⅧ:C and AT:A correlated with SOD(r equal to-0.905、-0.941、-0.946 and 0.817 respective,P<0.01). Conclusion In rat overlap syndrome when IH combined with pulmonary emphysema, hepatic inflammation and coagulability present mutual promotion effect and produce a more significant liver-derivative inflammatory and prothrombotic status.

Objective To compare the QTc and QTcd between type 2 diabetic and non-diabetic patients with post-myocardial infarction (post-MI) ,and to compare the QTcd in type 2 diabetic patients with post-MI treated with insulin,sulfonylurea,mefformin,or diet alone. Methods We measured the QTc and QTcd through simultaneous 12-lead Electrocardiogram in 138 post-MI patients,including 70 type 2 diabetic (of which,23 were assigned to re-ceive insulin,20 glipizide,16 mefformin,11 diet control) and 68 non-diabetic patients. Result Compared with post-MI patients without diabetes,those with type 2 diabetes had significantly higher QTc [(377.2±24.3) ms vs (342.9±27.5)ms,t=7.79,P<0.01] and QTcd [(48.8±19.7)ms vs (40.3±26.6)ms,t=2.14,P<0.05]. There were no significant difference between the mefformin group and the diet control group (P>0.05). The QTc and QTcd in the insulin group were significantly higher than those in the other three group s(P<0.05),and the QTc and QTcd in the glipizide group were higher than those in the mefformin group or diet control group(P<0.05,and P<0.01,respectively). Conclusion Type 2 diabetes is associated with an additional increase in the QTcd in post-MI patients,suggesting higher mortality risk in post-MI patients with type 2 diabetes. Insulin and glipizide may in-crease the QTc and QTcd in post-MI patients with diabetes. These effects were more significant in the insulin therapy group.

Objective:To investigate the frequency and severity of systemic adverse reactions in children with allergic rhinitis (AR) undergoing subcutaneous immunotherapy (SCIT).Methods:The clinical data of 321 children with allergic rhinitis receiving SCIT at Department of Otorhinolaryngology, Changzhou Third People′s Hospital from January 2016 to January 2020 were retrospectively analyzed. There were 180 boys and 141 girls aged 5 to 14 years. Patients were injected subcutaneously with standardized dust mites allergen extract. The onset time, symptoms and signs and treatment of adverse reactions were documented. The relationship of adverse reactions with gender, age, treatment course and dosage of allergen injection were analyzed.Results:Patients received total 13 053 injections, and 115 adverse reactions (0.88%) occurred in 56 cases (17.45%). The incidence of adverse reactions in children aged 5-9 years was higher than in those aged 10-14 years, for both the number of cases and injections (χ2=4.41, P=0.04; χ2=9.13, P<0.01), but no significant differences were observed in gender of patients. The incidence of adverse reactions in the age group 2-3 years was lower than that in age groups<1 year and 1-<2 years in both of cases and injections (χ2=22.86, P<0.01; χ2=6.43, P=0.01; χ2=12.14, P<0.01; χ2=13.74, P<0.01). The incidence of adverse reactions in the high-dosage phase (100 000 SQ-U) was higher than that in the low-dosage phase (<100 000 SQ-U) (χ2=4.35, P=0.04). Conclusions:The study shows that the incidence of adverse reactions in children with allergic rhinitis receiving subcutaneous immunotherapy is less than 1% in the number of injections and most of them are grade Ⅰ adverse reactions. The study also shows that younger age, the early course of treatment and the high dosage of allergens are risk factors for adverse reactions.

Argyrogramma agnata has been selected as a substitutive host insect for producing Dendrolimus punctatus Cytoplasmic Polyhedrosis Virus (DpCPV). In our experiment, it is very susceptible to DpCPV. The DpCPV produced in A. agnata is designated Aa-DpCPV. The cytoplasmic polyhedra body (CPB), the virion size and the shape of Aa-DpCPV are same as that of its original DpCPV (DpCPV-W1984). The RNA bands of Aa-DpCPV and DpCPV-W1984 all have 10 RNA segments respectively in 3% PAGE, which molecular weights ranged in size from 2.98×106 to 0.66×106 Dalton. Aa-DpCPV has the same strong toxicity as that of DpCPV-W1984 (from D. punctatus) to D. punctatus (Walker) larva. So it can be applied to the pine caterpillar control. The DpCPV yield in A.agnata is 2.5×108CPB/larva.
