Objective To observe the effects of phlorohlucinol on cervical dilatation. Methods Totaling 250 normal parturients were randomized into four study groups (50 in each group) and control group (n=50). Phloroglucinol was given in the study groups(group1,2,3 and 4)at the dose of 40 mg to the cervix and/or 160 mg and 200 mg intravenously during the latent phase. The control group (group1) received only atropine (0.5 mg) intravenously. Results The overall speed of cervical dilatation in the study group was (2.82?1.82) cm/h and (1.78?1.01) cm/h in the control group. The mean time of the first stage of labor was (14.23?1.11) h and (17.71?2.23) h in the study and control group, respectively (P

Objective To evaluate the different effect of 50 g glucose challenge test (GCT) on screening the glucose intolerance at different gestational age. Methods Two thousand pregnant women were divided into 2 groups(1000 in each). Women in group A received 50 g GCT at 14 and 28 gestational weeks respectively and 75 g oral glucose tolerance test (OGTT) were performed in those cases with abnormal 50 g GCT. 50 g GCT was performed after fasting at 14 gestational weeks and repeated one hour after a meal at 28 gestational weeks. Women in group B were screened by 50 g GCT at 28 gestational weeks and followed by 75 g OGTT for those with abnormal 50 g GCT. The diagnostic effect of 50 g GCT for screening at different weeks of gestation with different ways was evaluated. Results (1)The rate of abnormal result of 50 g GCT was higher in fasting cases than that of cases testing after meal (15.6% vs 12.2%, P

Objective To observe the effects of diazepam on the cervix in relieving spasm, eliminating edema and improving dilation during the latent phase of labor. Methods One hundred normal parturients were randomly devided into study group ( n =50) and control group ( n =50). The study group was injected diazepam 10 mg in the cervix during the latent phase. The control group was given 10 mg of diazepam by intravenous injection. Results The dilating speed of cervix in study group was 2.81?1.92 cm/h. The mean time of the first stage of labor was 11.13?1.21 h, while the control group was 1.98?0.92 cm/h and 13.34?0.44 h respectively. The differences between two groups were statistically significant ( P

Objective To evaluate the feasibility and efficacy of laparoscopic tubal anastomosis after tubal sterilization.Methods A total of 27 cases of fallopian tube anastomosis with tubal anastomosis were performed under laparoscopy.After removing the sterilized scar in the tubes the hydrotubation was carried out using Methylene Blue to detect whether the tube was patent.By using 6/0 absorbable thread,we sutured the mesosalpinx with 2 or 3 stitches to close the both ends of the fallopian tube.And then,isthmus-isthmus(1 whole-layer stitch at the 12 o'clock,and then 1-stitch sutures at the serous layer of the 8 and 4 o'clock respectively)ampulla-ampulla(1 whole-layer stitch at the 12 o'clock,and then 1-stitch sutures at the whole layers of the 9,7,5,and 3 o'clock respectively),or isthmus-ampulla(same method as the ampulla-ampulla anastomosis but more closed sutures)was performed.The patients received hydrotubation at the first day after the operation and then 3 to 5 days after the first menstruation.They were followed up for every 6 months till pregnancy.Results In the 27 patients(54 tubes),the rate of patency was 88.9%(48/54).The patent rate in the patients received isthmus-isthmus or ampulla-ampulla anastomosis was 86.5%(32/37)and 100%(15/15)respectively.In the 2 cases of isthmus-ampulla anastomosis,one was patent after the operation,and in the other,the Methylene Blue test showed anastomotic leakage.The hydrotubation performed at the first day after the treatment showed a rate of patent in 25 cases(2.6%,25/27),only two patient showed obstruction of the tube(7.4%,2/27).Follow-up was available in 26 of the patients up to over 6 months,19 of them had intrauterine pregnancy(73.1%,19/26)in 24 months after the procedure,among which 89.5%(17/19)occurred in 12 months;one(3.8%,1/26)patient developed ectopic pregnancy.Conclusions Laparoscopic tubal anastomosis is safe and effective for patients who desire reversal after sterilization.

Objective To analyze the effects of health management of metabolic syndrome on the control of related risk factors. Methods A total of 430 patients diagnosed with metabolic syndrome in 2008completed questionnaire and before randomly assigned to the health management group ( n = 207 ) and the control group (n=223). One year later, all the participants were investigated for the risk factors of food intake, cigarette smoking, alcohol consumption, staying-up and emotion, and the changes of body mass index ( BMI), blood pressure ( BP), triglyceride (TG), high-density lipoprotein cholesterol (HDL) and fasting blood glucose (FBG). Student's t test and x2 test were used for data analysis. Results For the health management group, the incidence of high-salt, high-fat and high-sugar intake, overtake of food, lack of physical exercises,staying-up and alcohol drinking was significantly decreased at 1 year (P ＜ 0. 05 ), when compared with baseline and the control group ( both P ＜ 0. 05 ). For the health management group, BMI,systolic blood pressure (SBP),TG and FBG was improved at 1 year (P＜0. 05). In comparison with the control group, BMI, SBP, diastolic blood pressure (DBP),TG and FBG of the management group were significantly improved (P ＜ 0. 05 ). Conclusions Patients with metabolic syndrome may have better treatment compliance after receiving systematized and individualized health management.

Four specific salt-tolerant fungi for dissolving phosphate rock (FM) w ere isolated from the coastal saline soils. It was found that the biomass and a b ility to release phosphate from the materials decreased with increasing of the N aCl content. During pH7.0～8.5, the biomass and ability of to release phospho rus from the materials of FM1 decreased sharply with pH rising, but the FM2 and FM4 decreased not considerably, optimal pH for FM3 was at pH8.5. At pH9.0, the bi oma ss and ability of to release phosphorus from the materials decreased quickly. F M2 was stable at alkaline and high salt content condition.

Objective To explore the role of miR-98 in peripheral blood mononuclear cells (PBMC) in the pathogenesis and development of childhood asthma.Methods A total of 43 cases of asthmatic children and 30 cases of healthy controls were enrolled in the study.Peripheral blood mononuclear cells were isolated in both healthy subjects and asthmatic children in acute attack and remission stages.The expressions of miR-98 and interleukin-4(IL-4) and IL-13 mRNA were detected by real-time quantitative PCR.Results The miR-98 levels of asthmatic children in attack stage were significantly lower than those in remission stage and control group (P<0.01).The IL-4 and IL-13 mRNA levels of asthmatic children in attack stage were significantly higher than those in remission stage and control group (P<0.01).There was no significant difference of miR-98,IL-4 and IL-13 mRNA between asthmatic children in remission stage and the controls (P>0.05).Furthermore,a negative correlation was found between the expression of miR-98 and IL-5(r=-0.794,P<0.01) and between the expression of miR-98 and IL-13 mRNA (r=-0.804,P<0.01) in asthmatic children in attack stage.A positive correlation was also found between IL-4 and IL-13 mRNA in asthmatic children in attack stage (r=0.853,P<0.01).Conclusion The expression of miR-98 decreased in asthmatic children,and miR-98 might be involved in the pathogenesis and development of asthma.

OBJECTIVE To investigate the etiology of acute respiratory tract infection(ARI)in Hefei area and risk factors that may influence the distribution of common pathogens.METHODS Direct immunofluorescence assay was applied to detect the respiratory syncytial virus(RSV),adenovirus(ADV),influenza virus A(FluA),influenza virus B(FluB),parainfluenza virus PIV(1,2,3)and real time fluorescent quantitation polymerase chain reaction (FQ-PCR)was applied to measuring Mycoplasma pneumoniae(MP)and Chlamydia pneumoniae(CP)in nasopharyngeal secretions and sputum specimens.RESULTS Among 530 cases included in this study,421 cases (79.43%)showed positive viral etiology.ADV accounted for 73(13.77%),FluA-68(12.83%),FluB-56 (10.56%),RSV-48(9.05%),PIVl-47(8.86%),PIV3-42(7.92%),PIV2-33(6.22%),MP-32(6.03%)and CP-22(4.15%).The detected positive rate of pathogens isolated in winter was the highest(85.07%).CONCLUSIONS Acute upper respiratory tract infection(AURTI)is common and more than 75%pathogens in Hefei area are virus in which the most commonly virus is ADV.Meanwhile atypical pathogens of infection should not be ignored.

Objective To determine the electrical conductivity of cerebrum, liver, lung and muscle of rats at different postmortem intervals for investigating the relationship between EC and PMI. Methods Healthy Sprague-Dawley rats were sacrificed and kept at constant temperature of 25°C. Cerebrum, lung, liver and muscle were extracted at different PMIs of immediate (0d), 1d, 2d, 3d, 4d, 5d, 6d and 7d, and their extraction liquids were prepared with ultrapure water at the ratio of 1g:10mL. EC were separately determined for different tissues and organs. The relationships between EC of different tissues and organs and PMI were analyzed and their regression functions were established. The characteristics of EC values for four tissues and organs were compared and their decomposition processes were discussed. Results EC of brain and muscle showed no significant changes within 1d, and increased rapidly during 2~7d; but EC of liver and lung started to increase within 1d and increased rapidly during 2~7d.The relationship between EC of different tissues and organs and PMI were well fitted with cubic equations and liver gained the highest coefficient (R2=0.96). Additional, the EC of four organs presented various increasing laws in different periods of PMI. Conclusion The EC of cerebrum, lung, liver and muscle of rats were well fitted with PMI and the determination of EC of cadaver tissues can be expected to become an effective method for PMI estimation in forensic practice.
