Objective To explore the clinical characteristics of multiple organs dysfunction syndrome (MODS) complicated with injury of pancreas.Methods A prospective study was carried out.From January 2011 to December 2012,a total of 69 patients with MODS in Department of Medical Intensie Care Unit,Fujian Provincial Hospital,Fujian Medical University were divided into 2 groups at admission.Patients of group A were suffered from MODS complicated with pancreas injury while patients of group B had MODS without complicatios.They were compared and evaluated by acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,6-hour clearance rate of lactic acid,incidence of shock,fluid resuscitation in the first 24 and 48 hours,bladder pressure and 28-day accumulative mortality.Results APACHE Ⅱ score in group A was significantly higher than that in group B (P ＜ 0.01).Compared with group B,the 6-hour clearance rate of lactic acid was lower,the incidence of shock increased obviously,and larger volume of fluid resuscitation was needed in the first 24 and 48 hours in the group A (P ＜ 0.05).Bladder pressure,incidence of feeble bowel sounds and the mortality in the group A were higher than those in group B,but the difference had no statistical significance (P＞0.05).Conclusions MODS complicated with pancreas injury is more severe than MODS without complications thereby resulting in higher incidence of shock and the poorer response to fluid resuscitation.

Objective To observe the changes of the endothelium-dependent vasodilatation(EDF)and serum vascular endothelial growth factor(VEGF)in the patients with impaired glucose tolerance(IGT)and type 2 diabetes mellitus(DM).Methods 30 IGT patients,30 type 2 DM patients and 33 normal subjects were divided into3 groups. Fasting glucose(FPG),fasting insulin(FINS),serum superoxide dismutase(SOD),maleie. dialdehyde(MDA)and VEGF were measured after 12 hours overnight fast. Oral 75g glucose tolerance test(OGTT)was performed. The inner diameter of braehial artery was assessed by a high resolution ultrasound system before and after reactive hyperemia. EDF was calculated as the percent change in brachial artery diameter 1 minute after reactive hyperemia compared with baseline. Results In the IGT group and DM group, EDF was significantly lower than that in NGT group(both P＜0.01),and EDF in the DM group was significantly lower than that in the IGT group(P＜0.01).SOD in the IGT group and DM group were significantly lower than that in the NGT group(both P＜0.01),but MDA in reverse(both P＜0.01).Compared with the IGT group, SOD in DM group was significantly lower(P＜0.01),but MDA was significantly higher(P＜0.01).VEGF was progressively increased in the NGT,IGT, DM groups. The difference between the two groups was significant(both P＜0.01).Stepwise regression analysis showed that EDF was positively related to SOD(r=0.418,P＜0.01,n=93),and negatively related to HOMA-IR and VEGF(r=-0.553,-0.221,both P＜0.01,n=93).VEGF was negatively related to SOD(r=-0.552,P＜0.01,n=93).Conclusion EDF is impaired in IGT patients while the impairment in DM patients becomes more marked. Insulin resistance, VEGF,SOD and MDA are closely related to the impairment of EDF in IGT and type 2 DM.

A model of classification techniques was established according to the sex and age by quantitative analy-sis of the risk factors for air popplution-induced respiratory diseases using the C4 .5 decision-making tree classifi-cation.The classification-based quantitative analysis was studied.The role of risk factors for respiratory diseases in 9 groups of people was assayed .This method can be used to analyze the risk factors for both respiratory diseases and other diseases in different populations, and can thus provide the evidence for their prevention and control.

Objective To investigate effects of changes in body composition and pancreas islet β-cell function on bone mineral density(BMD)in obese women with normal glucose metabolism at child-bearing age.Methods Ninety-five obese women with normal blood glucose at child-bearing age were recruited for the study,20 in non-obese group with body mass index(BMI)less than 23,20 in overweightgroup with BMI equal to or more than 23 and less than 25.28 in obesity Ⅰ group with BMI equal to or more than 25 and less than 30.and 27 in obesity Ⅱ group with BMI equal to or more than 30.Their BMD,body fat and lean mass were measured with by dual energy X-ray absorptiometer(DEXA),and intravenous -glucose tolerance test(IVGTT)was performed.Area under the Curve of insulin(AUCins)and acute jnsulin response(AIR)phase were calculated to assess their early insulin secretion.Homeostasis model assessment β-cell function index(HOMA2-%B)and homeostasis model insulin resistance index(HOMA2-IR)were used to assess their β-cell function and insulin resistance.Results Fat and lean mass in the upper and lower extremities.trunk and whole body and BMD in those women increased with increasing of their BMI(P＜0.05),particularly in fat mass.as well as their otller parameters including plasma insulin level at zerominute of IVGTT(IVGTTins0),AUCins.HOMA2-%B and HOMA2.IR(all P＜0.01).BMD in the upper and lower extremities,trunk and whole body showed a positive correlation with BMI,FPG,lean mass and/or fat mass.respectively(P＜0.05).BMD of the trunk and whole body also had a positive correlation with TVGTTins0,AIR,AUCins and HOMA2-IR.respectively(P＜0.05).Results of multivariate linear regression analysis showed that HOMA2-%B and HOMA2-IR correlated with BMD in a linear pattern.As the vailable body composition was added to the regression model.HOMA2 parameters would be removed from the model.Results of partial correlation analysis showed that islet β-cell function did not correlate with BMD after controlling body composition factors.Conclusions Insulin resistance or islet β-cell function compensation accompanied in obese women with main increase in fat mass have little benefit for their BMD,which may reflect indirectly their change in body compositions.Body composition,especially lean nlass,is the most important determinants of BMD in obese women.

OBJECTIVETo investigate the levels and influencing factors of phthalate internal exposure in pregnant women (gestation age ≤ 16 weeks).

METHODSDuring April to June in 2013, 1 020 pregnant women (gestation age ≤ 16 weeks) who had established the maternal care manual were recruited in maternal and child health hospital of Siming District, Xiamen city. Participators were asked to complete a questionnaire to obtain information on socio-demographic characteristics, lifestyle behaviors, and antenatal examination and to provide a urine sample. Finally, 998 pregnant women who provided a urine sample and completed the questionnaire were enrolled. Adopting systematic sampling method, 100 ones were selected randomly among 998 pregnant women. High performance liquid chromatography-electrospray ionization-tandern mass was used to determine the concentration of five phthalate monoesters in each urine, including mono-n-methyl phthalate (MMP), mono-ethyl phthalate (MEP), mono-butyl phthalate (MBP), mono-benzyl phthalate (MBzP), mono-ethylhexyl phthalate (MEHP). Based on the measurements and questionnaire data, multivariate logistic regression was used to analyze the association between the phthalate monoester levels and potential influential factors.

RESULTSThe detection rates of MMP, MEP, MBP, MBzP and MEHP in 100 pregnant urine samples were 94%, 93%, 87%, 83%, 99%, respectively. And the urinary median uncorrected concentrations of MMP, MEP, MBP, MBzP and MEHP in 100 urine samples were 20.56, 17.62, 10.15, 2.03, and 5.12 ng/ml, respectively. Specific gravity-corrected concentration were 20.81, 20.36, 12.88, 2.58, 5.00 ng/ml, respectively. The results of multivariate logistic regression analysis indicated that: education degree was negatively associated with urinary concentration of MMP, MEP, MBP, MBzP and MEHP, OR (95% CI) were 0.495 (0.253-0.966), 0.380 (0.191-0.755), 0.379 (0.186-0.774), 0.401 (0.196-0.819), 0.373(0.183-0.762), respectively. Participants who had hair permed and dyed during pregnancy had higher urinary level of MBP and MBzP, OR (95% CI) were 12.867 (1.240-133.525), 15.982 (1.367-186.911), respectively; Participants who use cosmetics during pregnancy had higher urinary level of MEP and MBP, OR (95% CI) were 2.977 (1.012-8.757), 4.440 (1.485-13.272), respectively; plastic bottled water consumption was positively associated with urinary concentrations of MEP and MEHP, OR (95% CI) were 3.780 (1.417-10.083), 2.699 (1.039-7.010), respectively; annual household income was negatively associated with urinary concentration of MMP, OR (95% CI) was 0.597 (0.372-0.959); individuals who took medications during pregnancy had higher urinary level of MEHP than non-takers, OR (95% CI) was 4.853 (1.084-21.732).

CONCLUSIONPregnant women whose gestation age was less than 16 weeks are generally exposed to phthalate. Phthalate internal exposure levels are significantly associated with most measured factors and the influencing factors with different phthalates internal exposure levels are different.
