Objective To know the indoor air pollution status in the newly decorated residential houses in Jiaozuo and to study the effect of decoration materials on the pollution. Methods To monitor formaldehyde, ammonia and benzene levels in the indoor air of 39 newly decorated rooms in Jiaozuo. Results The exceed standard rates of formaldehyde, ammonia and benzene in the indoor air were 73.6%, 84.7% and 25.8% respectively. Exceed standard rate of formaldehyde in the room which held the new furniture was the highest, 88.8%. Conclusion Decoration may cause indoor air pollution, the most part of the pollutants are formaldehyde and benzene. The level of the pollution depends on the different usages of the rooms.

Objective To evaluate the effects of 6% hydroxyethyl starch (HES)130/0.4 and 6% HES 200/0.5 on blood coagulation in patients undergoing major operation under general anesthesia.Methods Sixty ASA Ⅰ or Ⅱ patients aged 18-64 yr undergoing major operation under general anesthesia during which the blood loss was expected to be＞20%of blood volume were allocated randomly into 3 groups(n=20 each):Ⅰ control group(C);Ⅱ6% HES200/0.5 group (H) and Ⅲ HES130/0.4 group (V).In group H and V the patients Arterial blood samples were taken before(T1),immediately(T2)and 1 h after the end of fluid infusion(T3)for determination of hematocrit(Hct),platelet count(PLT)and prothrombin time(PT),platelet maximum aggregation test induced by 5 μmol/L ADP,and Sonoclot coagulation and platelet function analysis(gbACT,CR,PF,TP).Activated partial thromboplastin time(Am),coagulation factor Ⅷ (FⅧ)activity and von Willebrand factor(vWF)were measured only in group H and V.Results (1) PT and APTT were significantly prolonged after fluid infusion at T2 and T3 as compared with the baseline values at T1 in group H and V.(2)FⅧ activity and platelet maximum aggregation induced by ADP were significantly decreased at the end of fluid infusion at T2 as compared with the baseline at T1 but increased again at T3 in group H and V.(3)There was no significant change in Sonoclot coagulation parameters after fluid infusion as compared with the baseline except clot formation rate (CR)in group H and V.Conclusion Acute hypervolemic hemodilution with 6% HES130/0.4 or 200/0.5 has minimal effect on blood coagulation and there is no significant difference in blood coagulation changes induced by 6%HES130/0.4 and 200/0.5.

Induced pluripotent stem cell is a landmark in the stem cell study field, which has rapidly developed in the past 10 years.By obtaining induced pluripotent stem cells from somatic cell, and then differentiating into cardiomyocyte, various cardiomyocyte disease models could be established,which can be used for research of disease mechanisms, drug screening and gene therapy.This review introduces the successfully established cardiomyocyte disease models from human induced pluripotent stem cells, and points out the problems and prospects.

Objective The purpose of this study was to analyze the alterations of T_1、T_2 lymphocyte subsets in the peripheral blood of patients with colorectal cancer. MethodsTwenty patients with primary colorectal cancer were enrolled into this study, T_1 and T_2 in the peripheral blood were evaluated by detecting the intracellular interferon-? and interleukin-4 production with 4-color flow cytometry. ResultsThe percentage of T_1 and T_2 in the peripheral blood of cancer patients was lower significantly than healthy controls [(36?11)% and 3.3(1.9)% vs. (46?12)% and 4.1(3.1)%](P

The effect of Ultraviolet (UV) rays on the activity of parasporal crystal of Bacillus thuringiensis, var. Kurstaki HD-1 strain was studied by SEM, SDS-PAGE, bioassay and other methods. It was found that the morphology and surface structure of PC were damaged ,and its solubility in alkaline solution or silkworm gut juice was decreased after being irradiated by UV, the solubility was lost completely after a long time irradiation over 5 hours, so the processed PC could not be degraded into protoxin with insecticidal activity and was denatured.

V-P and MR tests were done at the same time using white porcelain board.The results showed that the white porcelain method was simple and convenient compared to the traditional method.

Objective To investigate the association between the target organ damage and morning blood pres- sure surge(MBPS) in the elderly hypertensives.Methods Three hundred thirty-two patients submitted to 24 h ambulatory blood pressure monitoring were categorized as with MBPS (n=173),and non-MBPS(n=149).Total cholesterol,body mass index(BMI),left ventricular mass index (LVMI),carotid endothelial medium thickness (CCA-IMT and ICA-IMT) and corrected QT dispersion(QTcd) were determined.Results 24 h,day and night mean systolic blood pressure in MBPS group were significantly higher than that in the non-MBPS group(P
