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.

Objective To investigate the effect of double lumen tube applied in the simple negative pressure drainage.Methods Forty cases were divided into two groups by a random table method,with 20 cases in each group. The double lumen tube was used in observation group while the normal gastric tube was used in control group,then the indexes on the drainage effect and wound healing were quantized and analyzed.Results In the observation group,one case suffered obstruction at 2 -4 days,1 case after 4 days of treatment,the obstruction rate was 10%.In the control group,two cases suffered obstruction at 2 -4 days,and 2 cases after 4 days of treatment,the obstruction rate was 25%.There was significant difference between two groups(χ2 =9.212,5.021,P =0.027,0.032).There were two cases of delayed healing and 17 cases with effective in the observation group,but 8 cases delayed healing and 11 cases with effective in the control group,there was statistically significant difference (χ2 =5.833,4.800,P =0.016, 0.028).Conclusion Double lumen tube can delay the occurrence time and reduce the occurrence rate of obstruction in simple negative pressure drainage,which promotes wound healing,and it is worth popularizing and using clinically.

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.

Objective To study the clinical manifestations and surgical treatment in renal transplant recipients with benign prostatic hyperplasia (BPH). Methods From January 2013 to May 2015, 5 patients of kidney transplant recipients who suffered from BPH for transurethral resection of prostate (TURP) treatments were enrolled (kidney transplant recipients group) and 15 patients with the same surgical treatments during the same peoriod were enrolled too (common control group). The routine examination, urodynamic, sex hormone levels and and the clinical efficacy were observed. Results The levels of hemoglobin, total protein, urea nitrogen, creatinine, prostate volume , residual urine and maximum flow rate (Qmax) before operation between two groups had no significant differences (P>0.05). The level of testosterone in kidney transplant recipients group was significantly lower than that in common control group: (3.5 ± 1.2) mmol/L vs. (5.5 ± 2.2) mmol/L, P < 0.05. The level of estradiol in kidney transplant recipients group was significantly higher than that in common control group:(49.6 ± 13.8) mmol/L vs. (40.5 ± 16.4) mmol/L, P < 0.05. In kidney transplant recipients group, the levels of hemoglobin, total protein, urea nitrogen, creatinine before and after operation had no significant differences (P>0.05). After operation, the levels of hemoglobin, total protein, urea nitrogen, creatinine in two groups had no significant differences (P>0.05). In kidney transplant recipients group, the quality of life (QOL) score before operation was 5 scores in 4 cases and 6 scores in 1 case, and those after operation were zero in 3 cases and 1 score in 2 cases. Conclusions Under the sufficient preoperative preparation and assessment, the renal transplant recipients with BPH patients can improve the symptoms of urinary obstruction and obtain satisfactory clinical efficacy as common BPH patients.
