Objective To explore the impact of elective caesarean section and vaginal delivery on maternal pelvic floor dysfunction. Methods A total of 131 pregnant women from January 2014 to March 2015 in our hospital were divided into observation group which re-ceived elective caesarean section and control group which received vaginal delivery.All the maternal and neonatal clinical data were counted. The occurrence of pelvic floor dysfunction disease in postpartum women after 6 to 8 weeks was observed.The occurrence of vaginal wall pro-lapse,uterine prolapse,stress urinary incontinence (SUI)and maternal pelvic floor muscle damage between two groups were compared and analyzed.Results There were varying degrees anterior vaginal wall prolapse phenomenon occured on 31 cases in obervation group,the pro-lapse rate was 67.39%,compared with 92.94% of the control group,the difference was statistically significant (P <0.05).Observation group with 13 cases of descent vaginae posterior,the prolapse rate was only 28.26%,compared with 75.29% of the control group,the differ-ence was statistically significant (P <0.05 ).The maternal uterine prolapse rate of observation group was about 13.04%,compared with 35.29%(30 cases)of the control group,the difference was statistically significant (P <0.05).Observation group with 6 cases of maternal SUI, the probability is about 13.04%,compared with 29.41% of control group,the difference was statistically significant (P <0.05).There was no significant difference in deep and shallow maternal pelvic floor muscle between two groups(P >0.05).Conclusion To adopt elective cesar-ean section has a lower probabilities of postpartum pelvic floor dysfunction disease than that by vaginal delivery for maternal women,which is propitious to the recovery of pregnant women,while it has nothing to do with pelvic floor muscle damage.

The content of 3 batches of Ornithine aspartate for injection was 100.04%-100.64% and molar ratio was 0.982-0.989. The content is similar to the results de-termined by potentiometric titration with national standards. CONCLUSIONS:The method is simple,accurate,specific and sensi-tive,and suitable for the determination of the content and molar ratio of Ornithine aspartate for injection.

Objective To establish the proper review rules for the microscopic screening of urine samples tested by automatic urinalysis work station.Methods A total of 3 154 random urine samples were enrolled to establish and validate review rules .All the samples were collected from the inpatients and outpatients of Shanghai First People′s Hospital from March to May 2013 and tested by urinalysis work station.Three thousands one hundred and fifty four urine samples were firstly tested by urinalysis work station,including both urine dry chemical analyzer and urine sediments analyzer .Then each urine sample was examined microscopically by two technicians-in-charge using double-blind method.The average results from the two technicians were used as review results .Compared with review results ,the review rules were set up.According to different test methods by automatic urinalysis work station , four microscopic review protocols were defined:(1)Protocol 1:based on chemistry results only ,microscopy review was performed when any of WBC,RBC,PRO and NIT was positive;(2)Protocol 2:based on urine sedimental analysis only ,microscopy review was performed when any of WBC ,RBC and CAST count was over upper limit of the reference range;(3)Protocol 3:if any of BLD ,RBC,LEU,WBC was different between two systems ,or quantitative results had two or more than two gradient differences ,microscopy review was performed;(4) Protoco1 4:if any of BLD, RBC,LEU ,WBC was different between two systems , or CAST was over upper limit of the reference range , or alarm appeared , microscopic review was performed .400 randomly selected urine samples were tested to validate the review rules .Omission diagnostic rate and review rate were used to evaluate the rules .Results According to the review rules,the positive samples rate was 43.47%(1 371/3 154) and the negative rate was 56.53%( 1 783/3 154 );Positive samples were composed of RBC ( 55.58%) , WBC ( 59.66%) and CAST(6.42%).The review rates of four protocols were 44.48%(1 403/3 154),45.69%(1 441/3 154), 26.09%(823/3 154),28.95%(913/3 154),respectively.The false negative rates (omission diagnostic rates)were 7.13%(225/3 154),4.53%(143/3 154),2.73%(86/3 154) and 1.02%(32/3 154), respectively .Protocol 4 was selected as an ideal plan.Additional 400 urine samples were tested using protocol 4 in order to confirm the review rule.The review rate, false negative rate were 26.25%(105/400), 0.75%( 3/400 ), respectively.After image review revised, the review rate was 14.50%(58/400).Conclusion This study formulates that the automatic urine analysis workstation review rules have clinical maneuverability and validity.

PcoI-PcoR is a quorum-sensing (QS) system influencing the biofilm formation and rhizosphere colonization in Pseudomonas fluorescens 2P24. The expression of the pcoI, a N-acyl-homoserne lactone (AHL) biosynthase gene, is under the regulation of a number of chromosomal factors, such as the GacS-GacA two-component system. In this paper, we investigated the upstream regulators that influence the transcription of pcoI gene using a chromosomal pcoI-lacZ fusion reporter strain PM203. Cosmids containing genomic DNA of the wild-type strain 2P24 were introduced into the reporter strain PM203 (gacA—, pcoI-lacZ) to screen positive transcriptional regulators of pcoI gene. One of them named pP32-24, which contained a 5-kb Pst I functional fragment was selected. Further analysis identified that the pcoI was the gene responsible for the increase of the pcoI-lacZ expression. The expression of pcoI-lacZ reporter was alsoimproved in both PM101 (pcoI-lacZ) and its gacAmutant PM203 after addition of exogenous AHL, indicating that the expression of pcoI is positively regulated by AHL (autoinduction) in strain 2P24. In addition, deletion mutagenesis and complementation experiments demonstrated that the transcriptional regulator PcoR positively controlled the expression of pcoI and the formation of biofilm. These results suggest that, in strain 2P24, the expression of PcoI-PcoR QS system is auto-inducted, and the transcriptional factor PcoR is involved in the regulation of pcoI transcription and the biofilm formation.

Objective To investigate the relationship between serum uric acid ( SUA) concentration and urinary albumin excretion rate ( UAER) and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitua (T2DM). Methods The clinical data of 372 patients with T2DM. including 184 males and 188 females, were collected. The correlations between SUA and the other clinical indexes were analysed by Pearson method, and multiple regression analysis was employed to examine the effects of various factors on UAER and CIMT. Results SUA concentration was higher in males than in females with T2DM (P <0. 01). and was positively correlated with UAER both in males and females with T2DM, even after adjustment for the creatinine clearance (r = 0.24, P < 0.01 for males; r = 0. 29, P < 0.01 for females). Positive correlation was found between SUA concentration and CIMT in females (r =0. 29, P < 0. 01). Multiple regression analysis demonstrated that SUA concentration was an independent determinant of UAER for males as well as females (β=0.16, P<0.05 for males; β=0. 20, P < 0. 05 for females), and was also an independent determinant of CIMT for females (β =0.16, P <0.05). Conclusion SUA plays an important role in the progression of diabetic nephropathy and cardiovascular diseases in patients with T2DM. SUA control may provide a novel approach for the treatment of diabetic nephropathy and vascular complications.
