Objective To investigate the relationship between the expression of urokinase-type plasminogen activator (uPA) mRNA and breast cancer, lymph node metastasis. Methods Sixty patients with breast tumor were selected randomly and the expression of uPA mRNA was detected with RT-PCR. The patients were divided into benign group (18 cases) and malignant group (42 cases) which included 22 cases with lymph node metastasis and 20 cases without lymph node metastasis. The relationship between uPA mRNA expression and breast cancer, lymph node metastasis was analyzed. Results Among these 18 benign tumors, low expression of uPA mRNA was found in 2 cases and the others were negative. While in 42 cases of malignant tumor, uPA mRNA were positive in 22 cases of lymph node metastasis, 16 of which were high expression, 5 of which were moderate expression, and 1 was low expression. uPA mRNA were positive in 18 of 20 cases of nonmetastatic lymph node, 1 of which was high expression, 5 of which were moderate expression and 12 of which were low expression, the other 2 were negative expression. The expression of uPA mRNA had significant difference between benign and malignant tumors ( P

Objective To investigate the clinical significance of Doppler flow waveform of ductus venosus (DV) in screening of fetal cardiac malformation.Methods Color Doppler ultrasonography was used to study DV flow in 240 normal fetuses and 20 fetuses with cardiac malformation that were screened out from the high-risk fetuses with congenital heart disease (CHD).Results ① The normal Doppler flow waveform of the DV was a characteristic triphasic pattern with forward flow during cardiac cycle,reflecting ventricular systole (S),ventricular diastole (D) and atrial systole (A).② In the group of 20 fetuses with cardiac malformation,eight had reverse flow and nine had decreased or absent flow during atrial contraction,the indices of the DV in fetuses with cardiac malformation were higher than those in gestational age-matched normal fetuses ( P

Objective To assess the safety and efficacy of an olive oil-based lipid emulsion for parenteral nutrition in patients after hepatectomy.Methods Thirty-one postoperative patients with elective hepateetomy were randomized to receive isonitrogenous,isocalorie parenteral nutrition over 6 days after liver lobectomy(48-72hours)with either olive oil-based lipid emulsion(study group,n=15)or standard soybean oil emulsion(control group,n=16).The liver function and plasma protoins were assessed using peripheral venous blood collected before surgery,one day after surgery,and 7 days after surgery.The safety profiles of emulsion supports and postoperative rehabilitation were also assessed.Results The preoperative serum levels of total bilirubin,direct bilirubin,alanine amiotransferase,aspartate aminotransferase,alkaline phosphatase,total protein,albumin,and prealbumin were comparable between the two groups(all P>0.05).Although the Postoperative safety profile and liver function were not significantly different between two groups(all P>0.05),plasma total proteins,albumin,and prealbumin returned to the normal levels significantly faster in the study group than in control group[(57.57±9.84)g/L vs.(47.76±6.53)g/L,P=0.000;(31.29±3.11)g/L vs.(26.34±4.87)g/L,P=0.000;(0.188±0.059)g/L vs.(0.103±0.037)g/L,P=0.000]on the 7th Postoperative day,and the Postoperative hospital stay was also significantly shorter in the study group[(13.1±1.2)d vs.(15.2±1.1)d,P=0.041].The incidence of postoperative complications in study group and control group was 26.7%and 31.3%.respectively.Conclusions Treatment with the new olive oil-based lipid emulsion is weU tolerated in hepatectomy patients.It can speed up plasma proteins recovery and may shorten postoperative hospital stay,although it does not remarkably decrease the incidence of postoperative complications.

Objective To investigate the clinical value of fetal echocardiography in prenatal diagnosis of fetal truncus artery. Methods Retrospective analysis was made in 10 cases with fetal truncus artery for their fetal echocardiography and follow-up findings. Echocardiographic characteristics was summed up in various fetal heart views. Results Truncus artery was confirmed by autopsy in 7 fetuses,and 3 cases were correspondingly verified by postnatal echocardiography. Echocardiographic characteristic images of fetal truncus artery was larger ventricular septal defect, only 1 great artery arising from heart, and pulmonary artery arising from truncus artery. Conclusions Echocardiography has important value in accurate diagnosis of fetal truncus artery and caution should be paid in differential diagnosis with other fetal complicated congenital heart diseases.

Objective:To investigate the effects of aerobic exercise on blood glucose and insulin levels in chronic intermittent hypoxic(CIH)rats and the underlying mechanisms, and to provide new insights for the prevention and treatment of diabetes caused by CIH.Methods:SD rats were randomly divided into the blank control group, CIH control group and CIH exercise group.After adaptive feeding, a rat model of CIH was established.The CIH exercise group received non-weight bearing exercise training through swimming.After 4 weeks, all rats were sacrificed and levels of total antioxidant capacity(T-AOC), reactive oxygen species(ROS), malondialdehyde(MDA), fasting blood glucose(FPG)and fasting insulin(FINS)were measured.Results:Compared with the blank control group and CIH control group, levels of ROS, MDA, FPG, T-AOC, FINS and FPG were significantly different in the CIH exercise group( F=4.60, 5.03, 4.87, 4.52 and 6.42, P=0.021, 0.015, 0.017, 0.022 and 0.006). Compared with the blank control group, levels of ROS, MDA, FPG and FINS increased and levels of T-AOC declined in the CIH control and exercise groups(all P<0.05). Compared with the CIH control group, levels of ROS, MDA, FPG and FINS decreased and T-AOC levels increased in the CIH exercise group(all P<0.05). Conclusions:CIH increases blood glucose and insulin levels by activating the oxidative stress response.Aerobic exercise can reduce the impact of oxidative stress on blood glucose and insulin levels.

Objective To observe the expression of small ubiquitin?related modifiers(SUMO)protein in normal cultured human lens epithelial cells(SRA01/04)and discuss regulation effects of SUMO protein on oxidative stress induced by high glucose. Methods The expression and local?ization of SUMO 1,2/3,4 was detected in normal cultured SRA01/04 cells through immunocytochemistry. The mRNA expression levels of SUMO 1?4 were examined by RT?PCR after the SRA01/04 cells treated with high glucose media at different concentrations and time points. Samples were grouped by medium concentrations(glucoses 5.5 mmol/L,12.5 mmol/L,25 mmol/L,50 mmol/L respectively for 24 h)and by treatment time(0 h, 6 h,12 h and 24 h respectively). After highly efficient transfection of GFP?SUMO2 into SRA01/04 cells,the survival and apoptotic rates of transfect?ed and un?transfected cells treated with high glucose was detected by CCK8 method and AV/PI double staining flow cytometry. Results The immu?nocytochemistry results showed that SUMO1,2/3,4 proteins were mainly located in the nucleus of SRA01/04 cells and part of SUMO2/3 was in the cytoplasm. RT?PCR results showed that compared with the low?glucose group,the mRNA expression of SUMO1?4 was increased along the increas?ing glucose concentration in the high?glucose group(P<0.05). Compared with 0 h,the mRNA expression of SUMO1?4 was enhanced at 6 h,12 h and 24 h(P<0.05)in the high?glucose group treated at 50 mmol/L concentration. Compared with the un?transfected cells,the survival rate was in?creased and the apoptotic rate was decreased in GFP?SUMO2 transfected cells in oxidative stress induced by high glucose(P<0.05). Conclusion SUMO protein was positively expressed in SRA01/04 cells and the expression of SUMO mRNA was affected by oxidative stress induced by high glu?cose.

Objective To analyze the relationship between daytime sleepiness and oxygen desaturation in the male eldcrly with obstructive sleep apnea /hyponea syndrome (OSAHS).Methods 147 male elderly (aged 60-80 years) with OSAHS in our sleep laboratory from March 2008 to February 2011 were divided into daytime sleepiness and daytime non-sleepiness groups. Epworth sleeping scale (ESS) and polysomnography (PSG) were employed to detect the degree of sleepiness.Oxygen desaturation were evaluated by oxygen desaturation index (ODI),average and minimum blood oxygen,time percentage of 90％ oxygen desaturation (CT90). Resulls There were significant differences between the two groups in body mass index (BMI) (t=4.157),ODI (t=-10.063),average (t=5.800) and minimum (U=916) blood oxygen,CT90(U=887)and apnca/hypopneaindex (AHI) (t =-11.361) (all P＜0.001).ESS scores were related with desaturation parameters of ODI,average and minimum blood oxygen and CT90 (r=0.683,-0.450,-0.583,0.507,all P＜0.001).ODI was correlated with average and minimum blood oxygen and CT00 (r=-0.628,-0.763,0.689,all P＜0.001).Among parameters of oxygen desaturation,only ODI had influence on ESS scores (odds ratio=1.11,95％CI:1.07 1.15),The sensitivity and specificity predicting daytime sleepiness at ODI ≥23 times/h were about 79.2％ and 84.3％,respectively.Conclusions Daytime sleepiness is associated with oxygen desaturaion and may be predicted by ODI through which average and minimum blood oxygen and CT00 are related with daytime sleepiness in the male elderly with OSAHS.
