Objective To analyze the Doppler indices of uterine artery at 11-16 weeks normal gestation. Methods Two hundred and ninty-seven normal pregnant women were consecutively recruited to take routine ultrasound examination at 11-16 weeks' gestation. According to gestational week, they were divided into 6 groups (11-11+6 weeks, 12-12+6 weeks, 13-13+6 weeks, 14-14+6 weeks, 15-15+6 weeks, 16-16+6 weeks). According to the location of placenta, they were divided into 3 groups (central placenta, right placenta, left placenta). Finally, the pregnant women were divided into 5 groups (RI<0.60 group, 0.60-0.69 group, 0.70-0.79 group, 0.80-0.85 group and ≥ 0.85 group) according to resistance index (RI). Doppler indices of uterine artery were measured in each case. Results (1) The PIm, RIm, S/Dm values (the mean PI, RI, S/D values of bilateral uterine artery) were decreased with the progress of pregnancy, but the difference of the RIm, S/Dm were not significant. Only the decrease of PIm after 15 weeks was significant (P<0.05). The mean PIm of each group was:11 weeks 1.96±0.39, 12 weeks 1.94±0.45, 13 weeks 1.79±0.43, 14 weeks 1.79±0.36, 15 weeks 1.51±0.43, 16 weeks 1.50±0.30. (2) The PI, RI, S/D values of uterine artery with placenta attached were lower than the other side. In the left placenta group, bilateral RI difference was-0.04 (t=-3.095, P=0.005), bilateral PI difference was -0.24 (t=-3.232, P=0.004), bilateral S/D difference was-1.00 (t=-2.965, P=0.007);in the right placenta group, bilateral RI difference was 0.04 (t=6.159, P=0.000), bilateral PI difference was 0.43 (t=6.614, P=0.000), bilateral S/D difference was 2.05 (t=6.378, P=0.000);in the middle placenta group, bilateral RI difference was 0.02 (t=4.150, P=0.000), bilateral PI difference was 0.14 (t=4.475, P=0.000), bilateral S/D differencewas 0.54 (t=4.376, P=0.000). (3) According to the RI, incidence rates ofα-notch detected:in<0.60 group both sides were 0;in 0.60-0.69 group, left uterine artery was 0.08, right uterine artery was 0.08;in 0.70-0.79 group, left uterine artery was 0.34, right uterine artery was 0.31;in 0.80-0.85 group, left uterine artery was 0.65, right uterine artery was 0.72;in≥0.85 group, left uterine artery was 0.81, right uterine artery was 0.87. Conclusion The uterine artery Doppler indices of 11-16 weeks maybe a reliable and non-invasive method for examining uteroplacental perfusion.

Objective To investigate the correlations between social support and self efficacy of young and middle-aged patients with peritoneal dialysis. Method The status of social support and self-efficacy of 97 young and middle-aged patients undergoing peritoneal dialysis were investigated and the correlation were analyzed. Results The score on social was (28.0 ± 6.4), lower than the norm (P < 0.01). The score on self-efficacy was (2.38 ± 0.62). The level of confidence was lower in 28 cases (28.9%), high in 58 cases (59.8%), very high in 11 cases (11.3%). The self-efficacy was positively correlated with social support, subjective support and support utilization (all P<0.05). Conclusions The levels of social support and self-efficacy are lower than the norm in young and middle-aged patients undergoing peritoneal dialysis. The self-efficacy is positively correlated with social support including subjective support and support utilization, which indicates that improved social support is effective for the improvement of self-efficacy by providing patients with family and social support.

ObjectiveTo study the changes of cellular immunity caused by intravenous infusion of allogenic rhesus mesenchymal stem cells (MSCs).MethodsMSCs were isolated and cultured.Then the immunomodulatory effects after MSCs infusion were evaluated by means of peripheral blood counts,mixed lymphocyte reaction (MLR) and analysis of lymphocytic subgroup. ResultsMSCs of rehsus were successfully cultivated. No acute toxicities or GVHD were observed in recipients. No obvious changes of peripheral blood counts were present. Recipients A2, A3, A4 were administered with MSC by 4.0 ×105/kg, 1.0 ×106/kg, 2.0×106/kg respectively and relative reaction (RR) of MLR decreased 14 days post MSCs infusion: from 46±2.6 ％to 40.4±1.73 ％ (F =10.19, P =0.023), from (40.9±2.3) ％ to (33±2.1) ％ (F =2.593, P =0.013), from 48.3±2.0 ％ to 39±1.0 ％ (F =28.431, P =0.003) respectively. The decrease degree (ARR) was positively related to the amount of MSCs(F =27.413, P =0.038). RR was restored within 30 days post MSCs infusion. After MSCs infusion, CD3+ CD3+CD4+ and CD3+CD8+ T-lymphocytes decreased in recipient A4, who was administered with the largest number of MSCs, and restored within 30 days. ConclusionMSCs infusion without any other treatment could temporarily inhibit immunity of T lymphocytes in MLR and the immunity inhibition was positively related to the amount of MSCs.The specific immunological characteristics of MSCs were demonstrated with extensive prospect in clinical research.

Objective To investigate the relationship between peri-menopausal women blood lipid level and the gallstone disease in order to provide theoretical basis for the prevention of gallbladder stone.Methods Seventy-two patients with gallbladder calculus from Department of Hepatobiliary Surgery Jinshan District Central Hospital of Shanghai and 52 healthy women coming for physical examination as the control group.Participants were divided into five age groups (20-29,30-39,40-49,50-59 and 60-69 years old) and two age stages (young period (30-40 years old) and peri-menopausal period (45-55 years old)),total cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL-C),low-density lipoproteins (LDL-C) and Body Mass Index (BMI) were determined and compared between the stone group and the control group at different age stages.Results In comparison of the menopausal transition period,the stone group had significantly lower blood TC,HDL-C and LDL-C levels than the control group (TC:(4.58 ± 0.27) mmol/L vs.(5.15 ± 0.26) mmol/L,t=3.112,P ＜0.01 ;HDL-C:(1.17 ±0.11) mmol/L vs.(1.40 ±0.08) mmol/L,t =3.351,P ＜0.01 ;LDL-C:(2.71 ± 0.30) mmol/L vs.(3.15 ± 0.26) mmol/L,t =2.437,P ＜ 0.05).For the young period,there were no significant difference on blood lipid level and BMI was observed between the stone group and the control group (P ＞ 0.05).The fat HDL-C level in blood was significantly lower in the stone group in the menopausal transition period than in the young period ((1.17 ± 0.11) mmol/L vs.(1.33 ± 0.07) mmol/L,t =2.455,P ＜ 0.05).The control group had significantly higher peri-menopausal TC,TG,LDL-C levels in blood and BMI than those in the control group young period (P ＜ 0.05) ; And HDL-C level,no significant difference (TC:(5.15 ± 0.26)mmol/L vs.(4.47 ± 0.34) mmol/L,t =3.175,P ＜ 0.01 ; TG:(1.88 ± 0.39) mmol/L vs.(1.10 ± 0.24)mmol/L,t=3.066,P＜0.01;LDL-C:(3.15 ±0.26) mmol/L vs.(2.71 ±0.31) mmol/L,t =2.261,P＜0.05;BMI:(24.75±0.99) kg/m2vs.(21.73±1.11) kg/m2,t=4.217,P＜0.01).Conclnsion For perimenopausal (45-55 years old) females,decline of serum TC,HDL-C and LDL-C levels may be related to the formation of cholesterol stone.Lower HDL-C level is closely associated with formation of cholesterol stone,indicating that it may be one of the measures to prevent gallbladder stone by adjusting blood fat in perimenopausal women.

Objective To investigate the status and analyze the influencing factors of structural empowerment and psychological empowerment of midwives in Suzhou.Methods Using convenience sampling,totally 309 midwives from fifteen hospitals in Suzhou were investigated with the Conditions of Work Effectiveness Questionnaire-Ⅱ (CWEQ-Ⅱ) and Psychological Empowerment Scale (PES).Results The scores of structural and psychological empowerment of midwives were (18.07±3.12) and (14.82±2.01).There was a significantly positive correlation between midwives' structural and psychological empowerment (r=0.396,P＜0.01).Hospital level and whether participate in midwifery standardization training had an impact on structural empowerment score(P＜0.05).Age,parental status,job title,salary,delivery room working hours,number of night shifts per month,and whether or not participate in teaching had an impact on psychological empowerment score(P＜0.05).Conclusion Midwives' structural and psychological empowerments are at a moderate level.Administrators should take targeted intervention to create an empowerment-allowing working environment for midwives,stabilize midwives work force,strengthen midwifery discipline construction and make full specialized features of midwives.

Objective To explore the proliferation property of vascular smooth muscle cells (VSMCs) in the stable CMKLR1 gene knock-down mouse VSMCs line and explore related mechanism.Methods The short hairpin RNA sequence targeting to knockdown the coding regions of mouse CMKLR1 mRNA was synthesized and subsequently employed to construct recombinant lentivirus vector.Mouse VSMCs were cultured and infected with the recombinant lentivirus (knockdown VSMCs).mRNA and protein CMKLR1 expression in Knockdown VSMCs was measured by real-time PCR and Western blot and compared with those in normal VSMCs (vehicle VSMCs) and lentivirus control VSMCs (control VSMCs).The proliferation of normal,knockdown and control VSMCs was induced by platelet-derived growth factor-BB (PDGF VSMCs) and measured by cell number counting and BrdU.The phosphorylated c-Jun N-terminal kinase (p-JNK) protein was investigated by Western blot.Results The relative level of CMKLR1 mRNA in knockdown VSMCs (0.23 ± 0.04) was significantly downregulated compared with which in vehicle VSMCs (1.05 ± 0.05) as well as control VSMCs (0.99 ± 0.04) (P ＜ 0.01).The relative level of CMKLR1 protein in knockdown VSMCs (0.29 ± 0.04) was also significantly decreased,compared with which in vehicle VSMCs (1.06 ±0.04) as well as control VSMCs (0.95 ±0.02) (P ＜0.01).The VSMCs number ((50.33 ± 1.20) × 103/cm2) and BrdU A450 value (1.80 ±0.05) in PDGF VSMCs were significantly increased in vehicle VSMCs ((42.02 ± 1.53) × 103/cm2,1.55 ± 0.04) (both P ＜ 0.05).Compared with those in vehicle VSMCs,the VSMCs number ((23.33 ± 2.03) × 103/cm2) and BrdU A450 value (1.32 ± 0.02) in knockdown VSMCs were significantly decreased.The proliferation property between PDGF VSMCs and control VSMCs was similar(P ＞0.05).Compared with the relative level of p-JNK protein (1.03 ±0.03) in vehicle VSMCs,the p-JNK protein level was significantly increased in PDGF VSMCs (1.36 ± 0.02,P ＜ 0.05) and significantly downregulated in knockdown VSMCs (0.79 ± 0.05,P ＜ 0.05).Conclusion Knockdowning CMKLR1 gene can reduce the proliferation of mouse vascular smooth muscle cells,which was related with the down-regulation of p-JNK expression.

Lead is one of the most important occupational hazards in China, and occupational exposure is the leading cause of lead poisoning. Lead can be absorbed by the body through air, food, drinking water and skin, and accumulate in multiple organs in the body, posing health risks to humans, especially to lead workers. Many previous studies have shown that lead can affect the function of glial cells such as microglia, astrocytes and oligodendrocytes, resulting in irreversible neurological damage. This article provides an overview of the neurotoxic mechanism induced by lead through glial cells, elucidates that lead can induce neurodegenerative diseases such as Alzheimer′s disease, Parkinson′s disease, and amyotrophic lateral sclerosis, and reviews the relationship between lead and glial cells, in order to provide reference for further research on the neurotoxic mechanism of lead on glial cells.
