Objective To explore the prevalence and the relative factors of the overweight and the obese in a population of Gansu Province pre-pregnancy women.and the effects of pre-pregnancy maternal body mass index (BMI) on gestational weight gain and pregnant outcome.Methods We conducted a populationbased birth cohort study in Gansu Province Maternity and Child Health Care Hospital from February,2010 to December,2011.Single live term birth women who have complete anthropometry were enrolled this study.They were categorized into four BMI groups according to World Health Organization's BMI recommendations for Asian populations.We explored the prevalence and the relative factors of the overweight and the obese,and the effects of pre-pregnancy maternal body mass index on gestational weight gain and birth outcomes by Chi-square test,analysis of variance.Results A total of 6 400 cases included in this study.The BMI range is from 13.3 to 38.1,the average BMI is (20.6 ±2.7).Among 6 400 cases,636 cases(9.9％) and 416 cases (6.5％) were overweight and obese.The average age (unit:years) is increase gradually in low weight group (27.8±3.8),normal group (29.1 ±4.3),overweight group (30.3 ±4.7) and obese group (30.6±4.6),the difference was statistically significant (F=77.490,P＜0.01).The result prompt that the median BMI increased with the increasing of maternal age (r=0.18,P＜0.01).The BMI of multiparous women (21.22 ±2.63) is higher than nulliparous women (20.43 ± 2.64),the difference was statistically significant (t=-9.630,P＜0.01).The BMI has negatively correlated with education level and economic income level (r=-0.06,P＜0.01; r=-0.04,P=0.036).With the increase of BMI,the weight gain of early (13 weeks) pregnancy (F=8.892,P＜ 0.01) and the total weight gain during whole pregnancy (F=21.700,P＜ 0.01) gradually reduced in four groups.The neonatal birth weight in overweight group is largest,in turn higher than obesity group,normal group and low weight group,the difference was statistically significant (F=11.261,P＜0.01).With increasing BMI,the incidence of pre eclampsia (x2=85.758,P＜0.05),gestational diabetes mellitus (x2=58.913,P＜0.05),postpartum hemorrhage (x2=13.501,P＜0.05),neonatal hypoglycemia (x2=6.563,P＜0.05) and neonatal pulmonary hyaline membrane (x2=9.579,P＜0.05) was increased.The incidence of caesarean section (x2=125.442,P＜0.05),macrosomia (x2=62.963,P＜0.05) and birth defects (x2=9.087,P＜0.05) also increased.The incidence of abnormal umbilical cord in overweight group is highest,in turn higher than normal group,low weight group,and the obesity group (x2=15.82g,P=0.001).The incidence of neonatal electrolyte disorder in obesity group was higher than low weight group,normal group,and the overweight group (x2=12.092,P=0.007).The incidence of preterm birth in overweight group is highest,in turn higher than obesity group,normal group and the low weight group (x2=7.865,P=0.049).Compared with the normal group,the risk of caesarean section (OR=l.700,95％ CI:1.325-2.181),pre-eclampsia (OR=2.436,95％ CI:1.578-3.761),gestational diabetes (OR=3.182,95％ CI:1.049-9.653) and abnormal umbilical cord (OR=2.252,95％ CI:1.267-4.004) in overweight group was increased.the risk of pre eclampsia (OR=2.585,95％ CI:1.020-6.914),macrosomia (OR=2.484,95％ CI:1.017 6.070),neonatal electrolyte disorder (OR=4.430,95％ CI:1.290-t5.217) in obesity group was increased.Conclusions The median BMI before pregnancy increased with increasing maternal age,parity,but decreased with education level and income level.The weight gain of early (13 weeks) pregnancy and the total weight gain during whole pregnancy decreased with increasing BMI.Overweight and obesity before pregnancy increased the risk the caesarean section,preeclampsia,gestational diabetes,macrosomia and neonatal electrolyte disorder.

Background:Pancreatic cancer is obscure in onset and progresses rapidly with very poor prognosis. Photodynamic therapy( PDT)has been developed as a novel anti-tumor treatment modality since 1980s. At present,there are only limited researches on pancreatic cancer treated with PDT in vivo. Aims:To investigate the efficacy of quantum dots-RGD ( QDs-RGD)based PDT combined with gemcitabine for treatment of pancreatic cancer xenograft in nude mice. Methods:QDs-RGD probe was synthesized and nude mice bearing pancreatic cancer xenograft was established. Nude mice were imaged at 1,5,10 and 24 hours after injection of QDs-RGD and QDs by in vivo imaging system. Forty model nude mice were randomly divided into five groups:control group( without any treatment),simple illumination group( laser 630 nm, 120 J/cm2,20 min),PDT group(QDs-RGD 0. 5 nmol+laser irradiation),gemcitabine group(gemcitabine 50 mg/kg)and combination group(QDs-RGD 0. 5 nmol+laser irradiation+gemcitabine 50 mg/kg). All the nude mice were sacrificed 18 days later. Tumor weight and volume were measured and tumor inhibition rate was calculated. Results:Fluorescence of tumor was shown 1 hour after injection and became clearest at the 5th hour,then showing a decrescendo trend. Density of QDs surrounding tumor was significantly less than that of QDs-RGD and faded away at the 10th hour. Tumor weight and volume in PDT group,gemcitabine group and combination group were all significantly lower than those in control group and simple illumination group(P<0. 01),and those in combination group were significantly lower than those in PDT group and gemcitabine group(P <0. 05). No significant differences in tumor weight and volume were found between control group and simple illumination group(P >0. 05),as well as between PDT group and gemcitabine group(P >0. 05). Tumor inhibition rate in combination group,gemcitabine group and PDT group was 70. 5%,43. 5% and 37. 1%, respectively. Conclusions:QDs-RGD based PDT combined with gemcitabine can inhibit the growth of pancreatic cancer xenograft in nude mice,which introduces a new idea to the treatment of pancreatic cancer.

Methods:All rats of model groups were treated by CCl4 to establish the liver fibrosis model. Besides CCl4,the rats of liver-stagnation and spleen-deficiency group were treated by stimulating tails with forceps clip and gastric infusion of rhubarb decoction,and the rats of qi-deficiency and blood-stasis group were treated by the method of swimming-fatigue. Then every group was intervened by the relevant medicine. After all treatments,the HA and TGF-?1 in serum were examined. Results:The HA and TGF-?1 of model groups were significantly higher than those of the control group(P

Objective To investigate the value of interphase fluorescence in situ hybridization(FISH)technique and the detection of fusion gene in the diagnosis of acute myeloid leukemia(AML)M2 and M3 Methods FISH was used to detect the AML1/ETO fusion gene and/or PML/RARα fusion gene in incipient cases including 9 AML-M2, 12 AML-M3 and 10 AML undetermined as AML-M2 or AML-M3 primarily diagnosed by routine morphology though bone marrow,cytochemical staining and immunophenotyping,which can help diagnose and guide clinical therapy.Results 4 of 9 AML-M2 cases were AML1/ETO positive.Among 12 AML-M3 cases,10 were PML/RARα positive.1 case was detected AML1/ETO fusion gene.In 10 untonfirmed M3 or M2,3 case8 showed AML1/ETO,5 showed PMIJRARot fusion gene and the rest showed neither of the genes.Conclusion As a new technique of the molecular genetics,FISH is accurate, rapid and efficient.It would be of significance not only at diagnosis of AML,but also for subsequent clinical decision-making.

OBJECTIVE:To explore the effects of dobutamine on hemodynamics,tissue perfusion and respiratory function in patients with ARDS caused by septic shock. METHODS:Totally 26 patients with ARDS caused by septic shock were given Dobu-tamine hydrochloride injection 5 μg/(kg·min) by continuous pump for 20 min ,increasing by 5 μg/(kg·min) every 20 min to 15μg/(kg·min)for 6 h. Mean artery pressure(MAP)maintained at about 65 mmHg during continuous pump. Hemodynamic index-es [HR,MAP,cardiac output(CO),stroke volume(SV),total end diastolic volume(GEDV),intrathoracic blood volume index (ITBI),extravascular lung water index (ELWI),systemic vascular resistance index (SVRI)],tissue perfusion indexes (norepi-nephrine,urine volume,blood oxygen saturation,blood lactate)and ventilator parameter indexes(positive breathing pressure,min-ute ventilation volume,respiratory rate,peak inspiratory pressure and plateau pressure)of all patients were recorded before medica-tion,6,24,48 h after medication. RESULTS:There were no statistical significances in HR,MAP,GEDV,ITBI,blood oxygen saturation,blood lactate and respiratory rate before and after treatment (P>0.05). CO,SV,urine volume and minute ventilation volume of all patients 6,24,48 h after medication were significantly higher than before medication,and those indexes increased gradually as medication time. ELWI,SVRI,positive breathing pressure,peak inspiratory pressure and plateau pressure of all pa-tients after medication were significantly lower than before medication,and those indexes decreased gradually as medication time, with statistical significance(P<0.05). The levels of norepinephrine in all patients 24,48 h after medication were significantly low-er than before medication and 6 h after medication,with statistical significance(P<0.05);but there was no statistical significance between before medication and 6 h after medication(P>0.05). CONCLUSIONS:The early application of dobutamine ELWI,tis-sue perfusion and respiratory function in patients with ARDS caused by septic shock,and can keep hemodynamics stable.
