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.

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

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.

Delphi method is a kind of forecasting method with several rounds of consultation with experts. It has three major characteristics including anonymity,information feedback and statistical analysis of results. With the continuous development of the method,its application fields is widened from the initial development of sociology to clinical medicine,psychology,nursing and so on. Since pharmacy and clinical medicine is inseparable,Delphi method used in pharmacy field has become the new direction of pharmaceutical research,and it can provide a new method for the pharmaceutical regulations,medical risk assessment and development of clinical pharmacy. In the paper,the application of Delphi method in the field of pharmacy was summarized in order to provide new ideas for the development of pharmacy.

Objective To survey the value of quantitative detection of urinary endotoxin for the diagnosis of gram-negative bacteria infection in urinary system,in order to provide evidences for early diagnosis and treatment.Methods The levels of urinary endotoxin were detected by kinetic turbidimetric technique,at the same time urine was cultured and WBC,CRP were detected.Results In 379 patients with gram-negative bacteria infection in urinary system,132 patients were upper urinary tract infection and 247 were lower urinary tract infection.The level of WBC,CRP and endotoxin were 11.25(7.98,13.99)× 109/L,81.36(76.64,83.50)mg/L and 49.57(17.28,78.37)pg/ml in upper urinary tract infection patients and in lower uri-nary tract infection patients were 10.24(7.94,12.24)×109/L,70.46(70.46,77.32)mg/L and 21.18(21.18,37.31)pg/ml. The group of upper urinary tract infection was higher than lower urinary tract infection on CRP and endotoxin,and have sig-nificant difference between the two groups of patients (P<0.05).Analysis of ROC,the diagnostic Cut-off value of 39.7pg/ml,the sensibility and specificity of endotoxin for the diagnosis of gram-negative bacteria infection on upper or lower urinary system were 84.1% and 90.3%.Conclusion The levels of urinary endotoxin detected by kinetic turbidimetric technique is simple and efficient,and have significant diagnosis value of gram-negative bacteria infection on upper or lower urinary sys-tem.

Objective: To observe the clinical therapeutic effects of acupuncture at the bony clefts in combination with tuina therapy in the treatment of sprains and strains of minor joints at the four extremities. Methods: Ninety cases of sprains and strains of minor joints at four extremities [including metacarpophalangeal (metatarsophalangeal)joints] were divided randomly into three groups by the consulting order. Acupuncture group, in which 30 cases were treated by acupuncture at the bony clefts; tuina group, in which 30 cases were treated by tuina therapy; and observation group, in which 30 cases were treated by acupuncture at the bony clefts and tuina therapy. The treatment was given 6 times a week as one course of treatments, and the therapeutic effects were observed after 2 courses of treatments. Results: The cure rates of the observation group, the acupuncture group and the tuina group reached 50.0%, 20.0% and 16.7% respectively, and the total effective rates reached 93.4%, 70.0% and 73.3% respectively. There were statistical significance between the observation group and the acupuncture and tuina groups (P<0.05); while there was not a statistical difference between the acupuncture group and the tuina group. It was indicated that the therapeutic effect of the observation group was better than that of the acupuncture group and the tuina group. Conclusion: Acupuncture at the bony clefts in combination with tuina therapy is quite effective in the treatment of sprains and strains of metacarpophalangeal (metatarsophalangeal) joints.
