Clustering of metabolic risk factors and adverse pregnancy outcomes: a prospective cohort study.

BACKGROUND: The relative contributions of a cluster of metabolic risk factors to pregnancy complications are not fully understood. We investigated the correlation between clustering of metabolic risk factors and adverse pregnancy outcomes. METHODS: This prospective cohort study was performed on pregnant women who sought health care during their whole gestation in a women's and children's hospital. The pregnancy outcomes were also followed. Pre-pregnancy overweight/obesity, as well as pregnancy high triglycerides, low high-density lipoprotein-cholesterol, hyperglycemia and raised blood pressure were defined as metabolic risk factors. Adverse pregnancy outcomes included preterm delivery, small/large for gestational age, preeclampsia, gestational diabetes mellitus, neonatal asphyxia and foetal demise. Stratified analyses were conducted on a total of 5535 women according to classification in each metabolic risk factor. The adjusted odds ratio (OR) for adverse pregnancy outcomes according to the number of clustering metabolic factors was calculated using the logistic regression analysis. RESULTS: The number of metabolic risk factors and adverse pregnancy outcomes were positively correlated (Ptrend < 0.001). Compared with women without a metabolic risk factor, women with one metabolic risk factor had a risk (OR = 1.67 95%CI 1.42-1.96) of adverse pregnancy outcomes. Women with a cluster of two metabolic risk factors tended to develop more adverse pregnancy outcomes (OR = 3.32 95% CI 2.69-4.10), and the risk was much higher in women with a cluster of three or more metabolic risk factors (OR = 10.40 95%CI 7.37-14.69). CONCLUSIONS: Pregnant women with a cluster of metabolic risk factors are more likely to have adverse pregnancy outcomes. Copyright © 2016 John Wiley & Sons, Ltd.

Lipoprotein-associated phospholipase A2 is associated with postpartum hypertension in women with history of preeclampsia.

Both hypertension and preeclampsia (PE) are considered as inflammatory diseases. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an inflammatory marker associated with lipid metabolism. We aimed to study the correlation and predictive value of Lp-PLA2 in postpartum hypertension after PE. A group of 160 PE patients (PE group) and a separate group of 160 normal pregnant women (control group) were recruited from January 2010 to October 2011. The average age in the PE group was 28.4 ± 4.5 years and the average gestational age was 34.7 ± 1.1 weeks. The average age in the control group was 27.8 ± 4.5 years and the average gestational age was 35.5 ± 1.2 weeks. General information (including age, gestational age, parity, history of metabolic disease, family history of high blood pressure, height, body weight before childbirth, and blood pressure) and blood samples were collected for measuring Lp-PLA2 and lipid parameters. From February to April in 2013, 153 cases in the PE group and 132 in the control group were re-called. We assessed their postpartum health, pregnancy, height, weight, and blood pressure. Serum mass of Lp-PLA2 in the PE group (210.67 ± 17.98 ng/mL) was significantly higher compared with that in the control group (174.72 ± 30.26 ng/mL) (P < 0.01). The pro-gestation BMI, systolic blood pressure (SBP), diastolic blood pressure, total cholesterol, triglyceride, and low-density lipoprotein-cholesterol (LDL-C) were also significantly higher. Correlation analysis showed that the level of Lp-PLA2 and SBP (r = 0.31), LDL-C (r = 0.37) were positively correlated. The incidence of postpartum hypertension in the PE group was higher than that in the normal control group. Logistic regression analysis showed that prenatal Lp-PLA2 mass was an independent risk factor for PE postpartum hypertension (OR 1.134,95 % CI 1.086-1.185). ROC curve analysis showed that the sensitivity of predicting postpartum hypertension was 73.2% and the specific degree was 86.6%, with Lp-PLA2 level of 217.75 ng/mL for boundary value. The onset of postpartum hypertension in PE patients may contribute to vascular inflammation, which is associated with antepartum lipid metabolism.

[Incident and related risk factors of hypertension in women with a history of preeclampsia].

OBJECTIVE: To investigate the prevalence of hypertension in women with a history of preeclampsia (PE) and to estimate related risk factors. METHODS: In this prospective case-control study, we collected clinical data from 809 women with a history of PE and 3 421 women with normal pregnancy from January 2008 to June 2012. Between November 2012 and April 2013, 651 women in PE group and 2 684 women with normal pregnancy group were recruited at the same time for collecting postpartum data including blood pressure, blood glucose and blood lipid. Binary logistic regression analysis was applied to analyze the relative factors of postpartum blood pressure. RESULTS: Prevalence of hypertension in PE group was higher than those with normal pregnancy (17.2% (112/651) vs. 1.1% (30/2 684), P < 0.01). Prevalence of hypertension in severe PE and mild PE patients was similar (20.1% (58/289) vs. 15.2% (55/362), P = 0.103). Binary logistic regression analysis indicated that progestational body mass index (OR = 1.379, 95% CI: 1.257-1.510, P < 0.05) , antepartum systolic blood pressure (OR = 1.025, 95%CI:1.012-1.040, P < 0.05) , antepartum triglyceride (OR = 1.002, 95% CI: 1.002-1.410, P < 0.05) , antepartum fasting blood glucose (OR = 1.733, 95% CI: 1.047-2.870, P < 0.05) , postpartum body mass index (OR = 1.279, 95% CI: 1.199-1.363, P < 0.05), postpartum fasting insulin (OR = 1.107, 95% CI: 1.055-1.162, P < 0.05) , systolic blood pressure difference between antepartum and postpartum (OR = 1.024, 95% CI :1.011-1.037, P < 0.05) , difference on triglyceride value between antepartum and postpartum (OR = 1.26, 95% CI: 1.069-1.486, P < 0.01), difference value of HOMA-IR between antepartum and postpartum (OR = 2.448, 95% CI: 1.330-4.500, P < 0.01) and difference value of high density lipoprotein cholesterol between antepartum and postpartum (OR = 1.699, 95% CI: 1.277-2.260, P < 0.05) were associated with hypertension after pregnancy. CONCLUSIONS: Women with history of PE are associated with higher risk of postpartum hypertension. Increased blood pressure, abnormal glucose and lipid metabolism during pregnancy are major risk factors for postpartum hypertension.

[Evaluation of the diagnostic criteria of gestational metabolic syndrome and analysis of the risk factors].

OBJECTIVES: To investigate gestational multiple metabolic abnormalities aggregation and diagnostic criteria for gestational metabolic syndrome (GMS), and to analyze the risk factors of GMS. METHODS: A cohort study recruiting 309 pregnant women with preeclampsia, 627 pregnant women with gestational diabetes mellitus (GDM) and 1245 normal pregnant women was performed from January 2008 to December 2011 in Guangdong Women and Children's Hospital. Information regarding age, gestational weeks, basic blood pressure, admission blood pressure, height and body mass index(BMI)before pregnancy was recorded. Biochemical indicators including fasting plasma glucose (FPG), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), free fatty acids (FFA) were tested. GMS was diagnosed with three or all of the following conditions: (1) overweight and/or obesity before pregnancy (BMI ≥ 25 kg/m(2)); (2) hypertension with blood pressure ≥ 140/90 mm Hg (1 mm Hg = 0.133 kPa); (3) hyperglycemia:diagnosed as GDM; (4) dyslipidemia with TG ≥ 3.23 mmol/L. The incidence of GMS of the three groups were calculated and the risk factors were analyzed. RESULTS: (1) The age, gestational weeks, basic blood pressure, admission blood pressure, BMI before pregnancy of women with preeclampsia and women with GDM were significantly different compared to normal women, respectively (P < 0.01). (2) Biochemical indicators of women with preeclampsia were as following: FPG (4.6 ± 1.0) mmol/L, FINS (10.1 ± 5.6) mU/L, TC (6.3 ± 1.6) mmol/L, TG (3.9 ± 1.8) mmol/L, HDL-C (1.4 ± 0.4) mmol/L, LDL-C (3.0 ± 1.0) mmol/L, FFA (0.8 ± 0.4) mmol/L. And those in women with GDM were: FPG (4.7 ± 0.9) mmol/L, FINS (10.2 ± 5.8) mU/L, TC (5.7 ± 1.3) mmol/L, TG (3.2 ± 1.1) mmol/L, HDL-C (1.4 ± 0.4) mmol/L, LDL-C (2.7 ± 0.9) mmol/L, FFA (0.6 ± 0.3) mmol/L. In normal pregnant women they were: FPG (4.3 ± 0.5) mmol/L, FINS (9.0 ± 4.4) mU/L, TC (5.7 ± 1.1) mmol/L, TG (2.8 ± 1.1) mmol/L, HDL-C (1.5 ± 0.4) mmol/L, LDL-C (2.9 ± 0.8) mmol/L, FFA (0.6 ± 0.2) mmol/L. Statistic differences were found in preeclampsia and GDM women compared to normal women respectively (P < 0.01). (3) The prevalence of GMS in preeclampsia group and in GDM group was 26.2% (81/309) and 13.6% (85/627), statistically different from that of the control group (0)(P < 0.01). (4) Compared to normal women, women with preeclampsia had higher risk of developing GMS (OR = 1.62, 95%CI 1.31 - 2.00, P < 0.01). The risk factors were BMI (OR = 1.29, 95%CI 1.13 - 1.47) and TG (OR = 2.49, 95%CI 1.87 - 3.31). Also, women with GDM had higher risk of developing GMS than normal women (OR = 1.27, 95%CI 1.09 - 1.49, P < 0.01), and the risk factors were BMI (OR = 1.13, 95%CI 1.04 - 1.23) and TG (OR = 1.16, 95%CI 1.02 - 1.33). TG was the independent risk factor in both preeclampsia women and GDM women (P < 0.01, P < 0.05). HDL-C seemed to have less importance in identifying GMS (P > 0.05). CONCLUSIONS: According to the GMS diagnostic criteria used in this study, some preeclampsia patients and some GDM women had aggregation of multiple metabolic abnormalities including pre-pregnancy overweight/obesity, hyperglycemia, high blood pressure and dyslipidemia. TG was the independent risk factor for GMS. HDL-C seemed to have less importance in identifying GMS.

Antidepressant-like effects of shuyusan in rats exposed to chronic stress: effects on hypothalamic-pituitary-adrenal function.

This study was to investigate antidepressant activities of Shuyusan (a Chinese herb), using a rats model of depression induced by unpredictable chronic mild stress (UCMS). The administration groups were treated with Shuyusan decoction for 3 weeks and compared with fluoxetine treatment. In order to understand the potential antidepressant-like activities of Shuyusan, tail suspension test (TST) and forced swimming test (FST) were used as behavioral despair study. The level of corticotropin-releasing factor (CRH), adrenocorticotropic hormone (ACTH), corticosterone (CORT) and hippocampus glucocorticoid receptor expression were examined. After modeling, there was a significant prolongation of immobility time in administration groups with the TST and FST. High-dose Shuyusan could reduce the immobility time measured with the TST and FST. The immobility time in high-dose herbs group and fluoxetine group was increased significantly compared with the model group. After 3 weeks herbs fed, the serum contents level of CRH, ACTH, and CORT in high-dose herb group was significantly decreased compared to the model group. The result indicated that Shuyusan had antidepressant activity effects on UCMS model rats. The potential antidepressant effect may be related to decreasing glucocorticoid levels activity, regulating the function of HPA axis, and inhibiting glucocorticoid receptor expression in hippocampus.

Serum levels of the adipokine chemerin in preeclampsia.

OBJECTIVE: Hypothesising that maternal serum chemerin levels may be associated with preeclampsia, we investigated whether maternal serum chemerin levels differ between preeclamptic and healthy pregnant women. We also investigated the association of serum chemerin with metabolic parameters and the severity of the disease. METHODS: This case-control study included 144 women (72 healthy and 72 preeclamptic women) in the third trimester of a singleton pregnancy. Clinical data and maternal serum were collected. The two groups were carefully matched for maternal age and gestational age. The maternal levels of serum chemerin were determined by enzyme-linked immunosorbent assay. RESULTS: The serum chemerin levels were found to be significantly increased in the women with preeclampsia (258.85±86.64 ng/mL) as compared with the healthy pregnant controls (210.80±47.34 ng/mL) (P<0.001). The serum chemerin concentrations in the severely preeclamptic women (289.6±74.43 ng/mL) were higher than those in the mildly preeclamptic women (228.1±87.99 ng/mL) (P<0.001). A stepwise regression analysis showed that the serum chemerin levels significantly and positively correlated with systolic blood pressure (P<0.001), free fatty acids (P<0.05) and serum creatinine (P<0.01). CONCLUSIONS: Chemerin levels are significantly increased in preeclampsia and independently associated with markers of dyslipidemia and with the severity of the preeclampsia. Further studies need to show the onset of the chemerin increase and its putative involvement in the pathophysiology of preeclampsia.

Efficacy evaluation for depression with somatic symptoms treated by electroacupuncture combined with Fluoxetine.

OBJECTIVE: This study is to investigate the clinical therapeutic effects and safety of treating mild or moderate depression with somatic symptoms with electroacupuncture combined with Fluoxetine. METHODS: 95 cases of mild or moderate depression with somatic symptoms were randomly divided into a Fluoxetine group, and an electroacupuncture plus Fluoxetine group. Hamilton Depression Scale (HAMD) was used for the assessment of clinical therapeutic effects and Treatment Emergent Symptom Scale (TESS) was used for assessment of adverse reactions. RESULTS: The total effective rate was 77.27% in the Fluoxetine group and 78.26% in the electroacupuncture plus Fluoxetine group, showing no statistically significant difference between these two groups (P > 0.05). However, the treatment took effect after two weeks in the electroacupuncture plus Fluoxetine group but after four weeks in Fluoxetine group. During this time, a better therapeutic effect on depression with mild or moderate somatic symptoms was found in the electroacupuncture plus Fluoxetine group, which also had fewer adverse reactions than the Fluoxetine group. CONCLUSION: Electroacupuncture combined with Fluoxetine takes effect faster for relieving the somatic symptoms with fewer adverse reactions. It is worth popularizing clinically.

Thresholds for Ambulatory Blood Pressure Monitoring Based on Maternal and Neonatal Outcomes in Late Pregnancy in a Southern Chinese Population.

Background In contrast to the general population, outcome-derived thresholds for diagnosing ambulatory hypertension in pregnancy are not yet available. We aimed to identify and compare outcome-derived ambulatory blood pressure (BP) monitoring thresholds for adverse perinatal outcomes by using approaches related and not related to clinic BP in a southern Chinese population. Methods and Results Ambulatory BP monitoring was performed in a cohort of 1768 high-risk participants in late pregnancy who were not taking antihypertensive medications. Participants were followed for composite maternal (severe complications) and neonatal (pregnancy loss, advanced neonatal care, and small for gestational age) outcomes. Modeling of clinic BP-unrelated approaches revealed a nonlinear threshold effect of ambulatory diastolic BP on the composite outcome, with increased risk for daytime ≥79 mm Hg and 24-hour measurement ≥76 mm Hg. For other ambulatory BP components showing linear associations with outcome, the following thresholds were identified: 131 mm Hg for daytime systolic, 121 mm Hg for nighttime systolic, 130 mm Hg for 24-hour systolic, and 73 mm Hg for night-time diastolic BP. These thresholds unrelated to clinic BP were lower than the equivalents yielding a similar probability of outcome to clinic BP of 140/90 mm Hg and were comparable with equivalents to clinic BP of 130/80 mm Hg. Conclusions Using an outcome-derived approach unrelated to clinic BP, we identified rounded thresholds to define ambulatory hypertension in at-risk women in late pregnancy in a southern Chinese population as follows: 130/80 mm Hg for daytime, 120/75 mm Hg for nighttime, and 130/75 mm Hg for 24-hour measurement. For wider clinical applicability and to align both nonpregnancy and pregnancy ambulatory BP monitoring with an outcomes-based approach, prospective, multiethnic, international studies from early pregnancy onward will be required.

Excessive umbilical cord coiling confers risk of elevated nocturnal blood pressure and severe/early-onset preeclampsia.

BACKGROUND: The associations between umbilical cord coiling, feto-placental vascular resistance and maternal blood pressure (BP) are not well understood. METHOD: We retrospectively analyzed 502 pregnant women suspected of hypertensive disorders in the third trimester from a hospital-based cohort, who underwent ambulatory BP monitoring and umbilical artery Doppler velocimetry examinations within 14 days before delivery. By applying quantile regression, a significant quantile-dependent positive association between umbilical cord coiling index and umbilical artery pulsatility index (UAPIMOM; converted to multiples of median) was observed from above 0.75th quantiles for each parameter. RESULTS: Using the cutoffs both at the 0.75th quantile to define high umbilical cord coiling (≥0.28 coils/cm) and high UAPIMOM (≥1.30), respectively, a graded increase in BP level was observed from patients with both low, either high and both high categories. Multivariate linear and quantile regression revealed that the high umbilical cord coiling/high UAPIMOM interaction was significantly correlated with night-time mean DBP level. Moreover, umbilical cord hypercoiling (≥0.3 coils/cm) was significantly correlated with night-time DBP with an average increase of ∼5 mmHg from the 0.05th to 0.70th quantiles and independently predicted the occurrence of severe (odds ratio 2.32, 95% confidence interval: 1.22-4.41) and early-onset (odds ratio 2.43, 95% confidence interval: 1.18-4.97) preeclampsia after adjusting for covariates. Further mediation analysis showed that elevated high UAPIMOM (≥1.30) could explain 11.4% of the umbilical cord hypercoiling → high night-time DBP association. CONCLUSION: Therefore, this retrospective study identifies excessive umbilical cord coiling, and its interaction with increased feto-placental vascular resistance, as novel risk factors for nocturnal BP elevation and preeclampsia.

HELLP Syndrome Complicated By Pulmonary Edema: A Case Report.

HELLP syndrome is a combination of symptoms described as hemolysis, elevated liver enzymes and low platelets. HELLP is a common life-threatening complication of pregnancy thought to be a variant or complication of preeclampsia. In this case report, we aimed to present a woman with acute postpartum HELLP syndrome complicated by pulmonary edema after caesarean section following severe preeclampsia. Our experience suggests that early detection of HELLP syndrome and timely management will bring good outcomes.

Trimester-Specific Weight Gain and Midpregnancy Diastolic Blood Pressure Rebound During Normotensive Pregnancy.

The longitudinal exposure-response relationship between trimester-specific gestational weight gain (GWG) and blood pressure (BP) during pregnancy is not well understood. We retrospectively assessed 1112 uncomplicated, normotensive pregnant women whose body weight and BP were measured from 12+0 to 40+0 weeks of gestation from a hospital-based cohort. By using growth curve modeling, a J-shaped pattern dominated diastolic BP (DBP) changing dynamics, with a midpregnancy drop at 20+0 to 22+0 weeks followed by a rebound. Using group-based trajectory modeling, 3 distinctive trajectories of DBP were identified: high-J shaped (18.5%), moderate-J shaped (48.3%), and low-J shaped (33.1%), as well as 3 distinctive GWG trajectories: high increasing (14.7%), moderate increasing (48.6%) and low increasing (36.8%). A temporal coincidence between the maximal rate of GWG and DBP transition from its nadir to rebound was observed during 20+0 to 22+0 weeks. Moreover, women in the high-increasing GWG group had the highest probability of being in the high-J DBP group. The GWG rate during the late midsecond trimester (22+0 to 26+0 weeks) was consistently associated with an elevated DBP level: for every 200 g/wk increase, the multivariable-adjusted odds ratio was 1.27 (95% confidence interval, 1.13-1.43) for the trajectory shift to the high-J group and 1.20 (95% confidence interval, 1.07-1.35) for the occurrence of diastolic prehypertension after 37+0 weeks. Furthermore, adding a trimester-specific GWG rate (22+0 to 26+0 weeks) contributed to the incremental yield for the prediction of diastolic prehypertension after 37+0 weeks. Our results thus provide the timing and extent of gestational weight control relevant to the optimized BP level during pregnancy.

Efficacy and safety of monoclonal antibodies targeting interleukin-17 pathway for inflammatory arthritis: a meta-analysis of randomized controlled clinical trials.

T-helper 17 (Th17) pathway plays an important and distinct role in autoimmunity and inflammation. A growing body of evidence demonstrates that interleukin-17 (IL-17) is also synthesized in inflammatory arthritis tissues and exerts potent proinflammatory and joint-destructive activities. Clinical studies have been performed to evaluate the therapeutic efficacy of antibodies blocking the IL-17 signaling pathway in patients with rheumatoid arthritis (RA). In this study, we performed a meta-analysis to systematically evaluate the clinical effects of IL-17 antibodies in RA patients. By searching PubMed, five randomized, placebo-controlled randomized controlled clinical trials that tested three antibodies against IL-17A (LY2439821 and secukinumab/AIN457) and the IL-17A receptor (brodalumab) were identified. The primary outcomes that were analyzed include American College of Rheumatology (ACR) Improvement Criteria and Disease Activity Score in 28 joints (DAS28). Meanwhile, the safety and adverse effects were also systematically analyzed. The results of the meta-analysis demonstrated that IL-17 antibody is effective in ameliorating the RA symptoms. Specifically, IL-17-blocking antibody significantly reduced ACR20 and ACR50. It also dramatically reduced DAS28, an index that measures tenderness and swelling severity of joints. The side effects of and intolerance to the antibody treatment were higher than those in the placebo control. The analysis result provides evidence-based information for clinical use of these agents in the treatment of inflammatory arthritis.

Electroacupuncture Restores 5-HT System Deficit in Chronic Mild Stress-Induced Depressed Rats.

Objective. The current study is designed to investigate the antidepressant efficacy of electroacupuncture (EA) treatment by evaluating its effect on the synthesis, metabolism, reuptake, and receptors of 5-hydroxytryptamine (5-HT), so as to clarify the molecular mechanisms of EA for antidepression. Materials and Methods. Solitary combined with the chronic unpredictable mild stress (CUMS) was used to establish the rat model with depression. The depressed rats were supplied with EA treatment for 4 weeks, and the behavior change and the following indices including 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), monoamine oxidase A (MAO-A), tryptophan hydroxylase (TPH), 5-HT transporter (SERT), 5-HT1A, and 5-HT2A in hippocampus and prefrontal cortex were examined. Results. EA treatment significantly improved the behavior of rats and increased 5-HT level in hippocampus of depressed rats. Similarly, EA treatment could significantly increase protein and mRNA expression of TPH and 5-HT1A during 5-HT synthesis process in hippocampus of depressed rats. However, EA treatment had no effect on the activity of MAO-A and the expression of SERT protein and mRNA. Conclusion. Antidepressant efficacy of EA treatment can be accomplished through enhancing 5-HT synthesis, upregulating 5-HT1A level, and improving 5-HT content in brain and synaptic gaps.

Antidepressant effect of electroacupuncture regulates signal targeting in the brain and increases brain-derived neurotrophic factor levels.

Electroacupuncture improves depressive behavior faster and with fewer adverse effects than antidepressant medication. However, the antidepressant mechanism of electroacupuncture remains poorly understood. Here, we established a rat model of chronic unpredicted mild stress, and then treated these rats with electroacupuncture at Yintang (EX-HN3) and Baihui (DU20) with sparse waves at 2 Hz and 0.6 mA for 30 minutes, once a day. We found increased horizontal and vertical activity, and decreased immobility time, at 2 and 4 weeks after treatment. Moreover, levels of neurotransmitters (5-hydroxytryptamine, glutamate, and γ-aminobutyric acid) and protein levels of brain-derived neurotrophic factor and brain-derived neurotrophic factor-related proteins (TrkB, protein kinase A, and phosphorylation of cyclic adenosine monophosphate response element binding protein) were increased in the hippocampus. Similarly, protein kinase A and TrkB mRNA levels were increased, and calcium-calmodulin-dependent protein kinase II levels decreased. These findings suggest that electroacupuncture increases phosphorylation of cyclic adenosine monophosphate response element binding protein and brain-derived neurotrophic factor levels by regulating multiple targets in the cyclic adenosine monophosphate response element binding protein signaling pathway, thereby promoting nerve regeneration, and exerting an antidepressive effect.

A comparison study of metformin only therapy and metformin combined with Chinese medicine jianyutangkang therapy in patients with type 2 diabetes: A randomized placebo-controlled double-blind study.

The aim of this 26-week, double-blind, controlled clinical trial, was to compare the efficacy of monotherapy (metformin only) with combination therapy (Chinese medicine prescription JianYuTangKang [JYTK] plus metformin) on type 2 diabetes. All patients on metformin were randomized to receive authenticated JYTK (59 patients) or placebo JYTK (53 patients), 4.5g daily, for 26 weeks. Patients also received information regarding diet and exercise. Fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1C) level, and a lipid profile were measured before, during, and after the treatment. The results of the treatment group (JYTK plus metformin) were noninferior to those of the control group (metformin plus placebo) at 8 and 18 weeks. After 26 weeks of treatment, FPG levels decreased to 6.1±1.0mmol/L in the treatment group and 7.0±1.5mmol/L in the control group (p<0.01). HbA1C levels after 26 weeks were also significantly decreased in the treatment group compared with the control group (p<0.01). In addition, lipid profiles were also significantly different between the two groups. Integrated traditional Chinese and Western medicine therapy (JYTK plus metformin) for patients with type 2 diabetes mellitus may not only help improve glycemia and insulin sensitivity, but also help to modify the diabetes related lipid equilibrium. And thereby provides a basis for a novel, effective, and safe approach, to treat type 2 diabetic patients.

Gene expression profiling reveals different molecular patterns in G-protein coupled receptor signaling pathways between early- and late-onset preeclampsia.

UNLABELLED: Early-onset preeclampsia and late-onset preeclampsia have been regarded as two different phenotypes with heterogeneous manifestations; To gain insights into the pathogenesis of the two traits, we analyzed the gene expression profiles in preeclamptic placentas. A whole genome-wide microarray was used to determine the gene expression profiles in placental tissues from patients with early-onset (n = 7; <34 weeks), and late-onset (n = 8; >36 weeks) preeclampsia and their controls who delivered preterm (n = 5; <34 weeks) or at term (n = 5; >36 weeks). Genes were termed differentially expressed if they showed a fold-change ≥ 2 and q-value < 0.05. Quantitative real-time reverse transcriptase PCR was used to verify the results. Western blotting was performed to verify the expressions of secreted genes at the protein level. RESULTS: Six hundred twenty-seven genes were differentially expressed in early-compared with late-onset preeclampsia (177 genes were up-regulated and 450 were down-regulated). Gene ontology analysis identified significant alterations in several biological processes; the top two were immune response and cell surface receptor linked signal transduction. Among the cell surface receptor linked signal transduction-related, differentially expressed genes, those involved in the G-protein coupled receptor protein signaling pathway were significantly enriched. G-protein coupled receptor signaling pathway related genes, such as GPR124 and MRGPRF, were both found to be down-regulated in early-onset preeclampsia. The results were consistent with those of western blotting that the abundance of GPR124 was lower in early-onset compared with late-onset preeclampsia. The different gene expression profiles reflect the different levels of transcription regulation between the two conditions and supported the hypothesis that they are separate disease entities. Moreover, the G-protein coupled receptor signaling pathway related genes may contribute to the mechanism underlying early- and late-onset preeclampsia.

Prehypertension During Normotensive Pregnancy and Postpartum Clustering of Cardiometabolic Risk Factors: A Prospective Cohort Study.

The nonstratification of blood pressure (BP) levels may underestimate future cardiovascular risk in pregnant women who present with BP levels in the range of prehypertension (120-139/80-89 mm Hg). We prospectively evaluated the relationship between multiple antepartum BP measurements (from 11(+0) to 13(+6) weeks' gestation to term) and the occurrence of postpartum metabolic syndrome in 507 normotensive pregnant women after a live birth. By using latent class growth modeling, we identified the following 3 distinctive diastolic BP (DBP) trajectory groups: the low-J-shaped group (34.2%; DBP from 62.5±5.8 to 65.0±6.8 mm Hg), the moderate-U-shaped group (52.6%; DBP from 71.0±5.9 to 69.8±6.2 mm Hg), and the elevated-J-shaped group (13.2%; DBP from 76.2±6.7 to 81.8±4.8 mm Hg). Notably, the elevated-J-shaped trajectory group had mean DBP and systolic BP levels within the range of prehypertension from 37(+0) and 26(+0) weeks of pregnancy, respectively. Among the 309 women who completed the ≈1.6 years of postpartum follow-up, the women in the elevated-J-shaped group had greater odds of developing postpartum metabolic syndrome (adjusted odds ratio, 6.55; 95% confidence interval, 1.79-23.92; P=0.004) than the low-J-shaped group. Moreover, a parsimonious model incorporating DBP (membership in the elevated-J-shaped group but not in the DBP prehypertension group as identified by a single measurement) and elevated levels of fasting glucose (>4.99 mmol/L) and triglycerides (>3.14 mmol/L) at term was developed, with good discrimination and calibration for postpartum metabolic syndrome (c-statistic, 0.764; 95% confidence interval, 0.674-0.855; P<0.001). Therefore, prehypertension identified by DBP trajectories throughout pregnancy is an independent risk factor for predicting postpartum metabolic syndrome in normotensive pregnant women.

Antidepressant-like effect of essential oil isolated from Toona ciliata Roem. var. yunnanensis.

Depressive order is one of the most common psychiatric diseases, and Toona ciliata Roem. var. yunnanensis has shown many bioactivities in folk medicine. This study was designed to investigate the antidepressant-like effect of essential oil isolated from T. ciliata Roem. var. yunnanensis. Gas chromatography and mass spectrometry (GC-MS) was used to analyze the compositions of essential oil. The immobility time in the forced swimming test (FST), tail suspending test (TST), and open field test (OFT) were used to evaluate the antidepressive effects of essential oil. Furthermore, chronic mild stress (CMS) rats were established, and contents of dopamine (DA), norepinephrine (NE), and 5-hydroxytryptamine (5-HT) in the brain were determined by high-performance liquid chromatography-electron capture detector (HPLC-ECD). Western blotting was performed to investigate the effects of essential oil on the expressions of brain-derived neurotrophic factor (BDNF) protein in rats' brain. The GC-MS analysis showed that the main components of essential oil were estragole (6.16 %), ß-elemene (24.91 %), ß-cubebene (14.29 %), and γ-elemene (8.05 %). The results from the FST and TST demonstrated that the immobility time could be significantly reduced by essential oil (10, 20, 40, and 80 mg/kg), without accompanying changes in ambulation when assessed in the OFT. Additionally, the contents of DA, NE, 5-HT, and BDNF in the hippocampus of CMS rats could be increased by treatment with essential oil at doses of 20, 40, and 80 mg/kg. All these results suggested that essential oil could be considered as a new candidate for curing depressive disorders.

Cardiovascular risk factors in Chinese women with a history of gestational diabetes mellitus.

BACKGROUND: Women with a history of gestational diabetes (GDM) are at increased risk of developing cardiovascular diseases compared with normal women. This study aimed to evaluate the cardiovascular risk factors in Chinese women with GDM. METHODS: 453 women with GDM (cases) and 1,180 healthy women (controls) were included in this study. The post-partum examinations included 2 h 75 g oral glucose tolerance tests, lipid profiles, anthropometric measurements (blood pressure, height, weight) and documentation of medical history, diet, and lifestyle. RESULTS: Compared with controls, the risks of abnormal glucose metabolism, obesity, hypertension, metabolic syndrome in women with a history of GDM were 4.61, 1.30, 1.57 and 3.52, respectively. Fasting blood glucose, progestational body mass index (pBMI) and antenatal insulin resistance at antenatal visit were predictors for abnormal glucose metabolism. pBMI and antenatal diastolic blood pressure were predictors for hypertension. pBMI and weight gain during pregnancy were predictors for obesity/overweight. pBMI, antenatal systolic blood pressure and antenatal triglyceride were predictors for metabolic syndrome. CONCLUSIONS: Women with a history of GDM have increased rates of cardiovascular disease risk factors including abnormal glucose metabolism, obesity, hypertension, metabolic syndrome. pBMI is the common independent predictors of cardiometabolic disease in the post-partum.

Hippocampal gene expression in a rat model of depression after electroacupuncture at the Baihui and Yintang acupoints.

Preliminary basic research and clinical findings have demonstrated that electroacupuncture therapy exhibits positive effects in ameliorating depression. However, most studies of the underlying mechanism are at the single gene level; there are few reports regarding the mechanism at the whole-genome level. Using a rat genomic gene-chip, we profiled hippocampal gene expression changes in rats after electroacupuncture therapy. Electroacupuncture therapy alleviated depression-related manifestations in the model rats. Using gene-chip analysis, we demonstrated that electroacupuncture at Baihui (DU20) and Yintang (EX-HN3) regulates the expression of 21 genes. Real-time PCR showed that the genes Vgf, Igf2, Tmp32, Loc500373, Hif1a, Folr1, Nmb, and Rtn were upregulated or downregulated in depression and that their expression tended to normalize after electroacupuncture therapy. These results indicate that electroacupuncture at Baihui and Yintang modulates depression by regulating the expression of particular genes.
