Sex differences in hypertension are not well known. The present study was undertaken to detect the association of nine lipid-related gene polymorphisms and blood pressure variation beween men and ...women in the Bai Ku Yao population.
Genotyping of ATP-binding cassette transporter A1 (ABCA-1) V825I, acyl-CoA:cholesterol acyltransferase-1 (ACAT-1) rs1044925, low-density lipoprotein receptor (LDL-R) AvaII, hepatic lipase gene (LIPC) -250G>A, endothelial lipase gene (LIPG) 584C>T, methylenetetrahydrofolate reductase (MTHFR) 677C>T, proprotein convertase subtilisin-like kexin type 9 (PCSK9) E670G, peroxisome proliferator-activated receptor delta (PPARD) +294T>C, and Scavenger receptor class B type 1 (SCARB1) rs5888 was performed in 682 normotensives and 670 hypertensives.
The genotypic frequencies of LDL-R and SCARB1 in normotensives and ABCA-1, ACAT-1, LDL-R, LIPC, and MTHFR in hypertensives were different between males and females (P < 0.05-0.001). The genotypic frequencies of ABCA-1, ACAT-1, LDL-R, LIPC, MTHFR, PPARD, and SCARB1 in males and ABCA-1, LDL-R, LIPC, LIPG, and MTHFR in females were different between normotensives and hypertensives (P < 0.05-0.001). Systolic blood pressure (SBP) levels in male hypertensives were different among the LIPC, LIPG, PCSK9, and SCARB1 genotypes (P < 0.05-0.01); and diastolic blood pressure (DBP) levels were different among the ABCA-1, LDL-R, LIPC, LIPG, MTHFR, PCSK9, and PPARD genotypes (P < 0.05-0.001). SBP levels in female hypertensives were different among the LIPC, MTHFR, PCSK9, and PPARD genotypes (P < 0.05-0.01); and DBP levels were different among ABCA-1, ACAT-1, MTHFR, PCSK9, PPARD, and SCARB1 genotypes (P <0.05-0.001). The correlations between these polymorphisms and blood pressure levels were also observed.
Sex differences in blood pressure levels in this population may partly attribute to the differences in some lipid-related gene polymorphisms.
We investigate a collaborative-relay beamforming design for simultaneous wireless information and power transfer. A non-robust beamforming design that assumes availability of perfect channel state ...information (CSI) in the relay nodes is addressed. In practical scenarios, CSI errors are usually inevitable; therefore, a robust collaborative-relay beamforming design is proposed. By applying the bisection method and the semidefinite relaxation (SDR) technique, the non-convex optimization problems of both non-robust and robust beamforming designs can be solved. Moreover, the solution returned by the SDR technique may not always be rank-one; thus, an iterative sub-gradient method is presented to acquire the rank-one solution. Simulation results show that under an imperfect CSI case, the proposed robust beamforming design can obtain a better performance than the non-robust one.

To explore a new noninvasive method for Hb Bart' s hydrops fetus by using PCR amplification efficiency discrimination between cell-free fetal DNA (cffDNA) and cell-free maternal DNA in maternal ...plasma.
CffDNA samples from pregnant women bearing possible Hb Bart's hydrops fetus were collected. Fluorescent PCR and capillary electrophoresis (CE) were performed. Hb Bart's hydrops fetus was conclusively identified by different peak area ratio of products.
The peak area ratio of 30 cffDNA samples from Hb Bart' s hydrops fetus was much less than 1. However, the ratio of cffDNA sample from hydrops fetus due to other reasons was approximately equal to 1.
By using cffDNA fluorescent PCR and CE, a prenatal screening method for Hb Bart' s hydrops fetus was developed.
•1200 μg/mL F. schisandrae inhibited the growth of V.alginolyticus ND-01.•V. alginolyticus under high concentrations of F. schisandrae stress had insufficient ability in the whole biofilm formation ...process.•DEGs was involved in the following functional categories: metabolic process, single-organism process, catalytic activity and localization.
Due to the abusive use of antibiotics, bacterial resistance has become a global problem and poses severe threats to aquaculture. The drug-resistant diseases caused by Vibrio alginolyticus have caused significant economic losses to cultured marine fish. Fructus schisandrae is used to treat inflammatory diseases in China and Japan. There have been no reports of bacterial molecular mechanisms associated with F. schisandrae stress. In this study, the inhibiting effect of F. schisandrae on the growth of V. alginolyticus was detected to understand response mechanisms at the molecular level. The antibacterial tests were analyzed via next-generation deep sequencing technology (RNA sequencing, RNA-seq). Wild V. alginolyticus (CK) was compared with V. alginolyticus, F. schisandrae incubated for 2 h, and V. alginolyticus, F. schisandrae incubated for 4 h. Our results revealed that there were 582 genes (236 upregulated and 346 downregulated) and 1068 genes (376 upregulated and 692 downregulated), respectively. Differentially expressed genes (DEGs) were involved in the following functional categories: metabolic process, single-organism process, catalytic activity, cellular process, binding, membrane, cell part, cell, and localization. FS_2 h was compared with FS_4 h, and 21 genes (14 upregulated and 7 downregulated) were obtained. The RNA-seq results were validated by detecting the expression levels of 13 genes using quantitative real-time polymerase chain reaction (qRT-PCR). The qRT-PCR results matched those of the sequencing, which reinforced the reliability of the RNA-seq. The results revealed the transcriptional response of V. alginolyticus to F. schisandrae, which will provide new ideas for studying V. alginolyticus' complex virulence molecular mechanism and the possibility of developing Schisandra to prevent and treat drug-resistant diseases.

BACKGROUND： The prognostic factors related to lymph node involvement lymph node status, the number of positive lymph nodes, lymph node ratio （LNR） and the number of nodes evaluated in patients with ...pancreatic adenocarcinoma after pancreatectomy are poorly defined. METHODS： A total of 167 patients who had undergone resection of pancreatic adenocarcinoma from February 2010 to August 2011 were included in this study. Histological examination was performed to evaluate the tumor differentiation and lymph node involvement. Univariate and multivariate analyses were made to determine the relationship between the variables related to nodal involvement and the number of nodes and survival. RESULTS： The median number of total nodes examined was 10 （range 0-44） for the entire cohort. The median number of total nodes examined in node-negative （pN0） patients was similar to that in node-positive （pN1） patients. Patients with pN1 diseases had significantly worse survival than those with pN0 ones （P=0.000）. Patients with three or more positive nodes had a poorer prognosis compared with those with the negative nodes （P=0.000）. The prognosis of the patients with negative nodes was similar to that of those with one to two positive nodes （P=0.114）. The median survival of patients with an LNR ≥0.4 was shorter than that of patients with an LNR 〈0.4 in the pN1 cohort （P=0.014）. No significance was found between the number of total nodes examined and the prognosis, regardless of the cutoff of 10 or 12 and in the entire cohort or the pN0 and pN1 groups. Based on the multivariate analysis of the entire cohort and the pN1 group, the nodal status, the number of positive nodes and the LNR were all associated with survival. CONCLUSIONS： In addition to the nodal status, the number of positive nodes and the LNR can serve as comprehensive factors for the evaluation of nodal involvement. This approach may be more effective for predicting the survival of patients with pancreatic adenocarcinoma after pancreatectomy.
