Objective To investigate the change of adipocyte fatty acid-binding protein(FABP4) in maternal serum and umbilical cord blood and FABP4 mRNA placental expression in patients with preeclampsia(PE). Methods A total of 60 women with PE and 60 normal pregnant women as control participated in this study. All are admitted to Fujian Maternity and Children Health Hospital for delivery from December 2008 to October 2009. Patients with PE were divided into early-onset group (n = 30, presented at ≤34 weeks of gestation) and late-onset group(n = 30, presented at > 34 weeks of gestation), with 30 normal pregnant women as early control group(≤34 weeks of gestation) and 30 as late control group(>34 weeks of gestation). Enzyme-linked immunosorbent assay (ELISA) was used to detect FABP4,fasting serum glucose,fasting insulin(FINS) in maternal serum and FABP4 in umbilical cord blood. Real-time fluorescent quantitative revere transcription PCR was used to detect placental FABP4 mRNA expression. Furthermore,clinical and biochemical parameters were recorded, such as body mass index(BMI), systolic pressure(SP),diastolic pressure (DP), mean arterial pressure (MAP), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), creatinine (Cr), uric acid (UA) , glomerular filtration rate (GFR), 24 hours urine protein in pregnant women and neonatal weight. Results (1) Maternal serum FABP4 was (176 ± 9) ng/L in early-onset PE group and (170 ± 9) ng/L in late-onset PE group, significantly elevated as compared to (81 ± 13) ng/L in early control group and (94 ± 15) ng/L in late control group. (2) Mean maternal FINS, homeostasis model of assessment for insulin resistence index (HOMA-IR) were significantly elevated in the early-onset PE group and late-onset PE group as compared to control groups, respectively. (3) Mean placental FABP4 mRNA expression were significantly elevated in the early-onset PE group and late-onset PE group as compared to late control group. However, no significant difference was found in placental FABP4 mRNA expression between early-onset and late-onset PE groups.(4) Mean umbilical cord blood FABP4 concentrations were significantly decreased in the early-onset PE group and late-onset PE group as compared to late control group. Furthermore, umbilical cord blood FABP4 concentration correlated negatively with maternal serum FABP4 level and placental FABP4 mRNA expression, but positively with neonatal weight. (5) Mean maternal serum FABP4 concentrations correlated positively with placental FABP4 mRNA expression,TG, FINS, HOMA-IR, Cr, UA; and negatively with HDL, GFR. Conclusions Increased FABP4 expression in maternal serum and placenta may be involved in the pathogenesis of preeclampsia. Increased FABP4 mRNA expression in placenta may contribute to high serum FABP4 level in women with PE.

Objective To explore the status of toileting behavior and its relationship to lower urinary tract symptoms (LUTS) in female nurses. Methods A total of 636 nurses were selected from three top three hospitals in Jinan by multi-stage sampling. The nurses′toileting behavior and LUTS were assessed by Women′s Toileting Behavior Scale and The International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms. Univariate analysis and hierarchical regression analysis were conducted to examine the factors associated with LUTS. Results The nurse groups were widespread adverse toileting behavior. Delayed voiding was the most severe problem in nurses. Among LUTS storage symptoms were the most severe,voiding symptoms followed and incontinence symptoms were mild. Hierarchical regression analysis exhibited that factors associated significantly with LUTS included age, body mass index, menstrual status, working experience, history of urinary tract infection and poor toileting behavior (mainly hard urination, delayed voiding, and anuria urination),which explained 9.1%,12.9% and 12.6% of the variance of storage symptoms, voiding symptoms and incontinence symptoms, respectively. Conclusions Poor toileting behaviors are highly prevalent in nurses and they are closely related to LUTS, leading to concerns about possible effects of working environment and poor bladder habits on LUTS. Cognitive-behavioral intervention for this group is essential for delivering information about correct toileting behavior and its association with LUTS. Hospital administrators are suggested to pay more attention to nurses′working environment and its impact on nurses′health in order to improve their quality of life and job satisfaction.

Objective To descript the current situation and to analyze the impact factors of the stigma among the community women with urinary incontinence in Jinan.Methods This was a crosssectional survey by purposive sampling.506 women with urinary incontinence from 3 communities in Jinan were measured by the International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF) and the revised version of the Social Impact Scale(SIS)in order to get the information about the urinary incontinence type,severity degree and the stigma.Results The participants' total score of the SIS was (39.62±8.10) points and the score index was 55％.Score index of three subscale including social isolation,social exclusion and inner sense of shame were 58％,45％,70％; age and severity degree of urinary incontinence were independent factors and totally accounted for 14.0％ of the variance in stigma.Conclusions It suggested that,to make patients drop the cognitive errors about being incontinence,then decrease the stigma and improve the quality of life,the Health Care Sector should positively broadcast the relative knowledge of urinary incontinence and encourages patients to seek help,screen,diagnose,and get treatment earlier,and complete the tertiary prevention.

Objective:To investigate the role of reactive oxygen species (ROS) in the apoptosis of human hepatocellular carcinoma HepG_2 cells induced by PIG11 protein overexpression. Methods:The fluorescent probe 2', 7'-dichlorofluorescin diacetate (DCFH-DA) was used to label the intracellular ROS in pLXSN-PIG11-HepG_2 cells,pLXSN-HepG_2 cells and HepG_2 cells.The intracellular fluorescence intensity was detected by using the flow cytometry (FCM). The apoptotic ratio of HepG_2 was determined by FCM after elimination of intracellular ROS with 10 mmol/L N-acetylcystine (NAC). Results:The intracellular content of ROS in pLXSN-PIG11-HepG_2 cells was significantly higher than that in pLXSN-HepG_2 cells[(15.60±0.92) vs (4.90±0.70), P<0.01)]. The apoptotic ratio of pLXSN-PIG11-HepG_2 cells was significantly decreased by pretreatment with 10 mmol/L NAC (P<0.01). Conclusion:The apoptosis-inducing effect of PIG11 over-expression is related with elevation of intracellular ROS levels.

BACKGROUND:Under mitomycin C treatment, feeder cells appear to have restricted proliferation, but they are stil able to secret different cytokines. Non-mesenchymal stem cells from the bone marrow and secreted factors in plasma maintain the micro-environment suitable for the growth of mesenchymal stem cells that can improve the yield of mesenchymal stem cells.
OBJECTIVE:To study the biological characteristics of C57 mouse bone marrow mesenchymal stem cells isolated using a whole bone marrow adherent culture technique.
METHODS:Using the whole bone marrow adherent culture technique, purified and amplified C57 mouse bone marrow mesenchymal stem cells were harvested. cellproliferation kinetics, immune cellsurface markers, multiple differentiation potential and cellcycle were detected.
RESULTS AND CONCLUSION:Using the whole bone marrow culture, mouse bone marrow mesenchymal stem cells were harvested and capable of adhering to the plastic culture vessel. The obtained cells expressed CD45, CD105 and Sca-1, but were negative for CD34, CD33 and C-kit. The doubling time was (57.11±1.5) hours. The cells could be induced to differentiate into osteoblasts, adipocytes and chondrocytes. The cellcycle analysis showed that 64%of cells were in G 0-G 1 phase. These indicates that C57 mouse bone marrow mesenchymal stem cells isolated using a whole bone marrow adherent culture technique have biological characteristics of mesenchymal stem cells.
