Objective: To explore the effects of cardiac resynchronization therapy (CRT) in patients with dispersion of re-polarization and ventricular arrhythmia.
Methods: A total of 86 consecutive patents with CRT implantation were enrolled. According to weather absolute value of LVEF increased≥10% from baseline at 6 months after CRT implantation, the patients were divided into 2 groups: Response group and Non-response group,n=43 in each group. Dispersion of re-polarization indexes as QRS duration, QTc interval, TpTe interval and the events of ventricular arrhythmia were compared between 2 groups at different time points after CRT.
Results:①In Response group, compared with pre-operation, QRS duration and TpTe interval were shorter at 1 year and within 24h after CRT implantation, allP<0.05, while the above indexes were similar in Non-response group, allP>0.05.②During 1 year after CRT implantation, the incidences of PVCs and PVC runs in Response group were much less than those in Non-response group, for lgPVCs: (1.78 ± 0.77) vs (2.73 ± 0.61), for lgPVC runs: (0.64 ± 0.48) vs (1.98 ± 0.72),P<0.05.③Multi liner regression analysis demonstrated that TpTe interval within 24h after CRT implantation was an independent predictor for both lgPVCs: (B=0.143, OR=1.154,P=0.001) and lgPVC runs: (B=0.122, OR=1.047,P=0.001).
Conclusion: CRT ventricular reverse remodeling may reduce dispersion of re-polarization and the risk of ventricular arrhythmia, therefore improve the prognosis in relevant patients; TpTe interval within 24h after CRT had the predictive value for ventricular arrhythmia.

In this paper , we discussed the financing mechanisms of premarital healthcare services from their properties combined with the status quo financing in our country .We then provided the scientific basis and decision-making reference for improving financing mechanism to improve the premarital healthcare system .A literature or doc-umentary and field researches have combed the present situation of the premarital healthcare services financing mech -anisms at home and abroad .Related data were collected in eight research areas , namely Fujian, Guangxi, Yunnan, Hubei, Jiangsu, Heilongjiang, Beijing and Tianjin and the related personnel from health administrative department , civil affairs departments , maternal and child healthcare institutions were interviewed in terms of Field Research .From the main content at present , premarital healthcare services belong to the category of quasi-public goods .We dis-cussed the financing mechanisms from the financing levels , sources of funds , fund allocation , payment and financial regulatory and other aspects .Finally, some policy recommendations were put forward including making clear the na-ture of premarital healthcare service property , establishment of a special financial investment mechanism , unify the basic financing service standard after scientific feasibility studies , timely and fully allocate special premarital health-care service funds to strengthen the fund supervision policy recommendations .

Based on the policy framework , the premarital healthcare policy of Guangxi was analyzed from four aspects including policy background , process, content and actors.We analyzed the factors influencing this policy and their interactions , and discussed the important impact of Thalassemia prevention , multi-sectoral consensus and appro-priate premarital healthcare measures to the policy building and implementation .Then the lessons such as strengthe-ning the multi-sector cooperation , specifically making clear the pre-marital screening projects and implementing the“one-stop” service model were summed up in Guangxi province .Finally, combined with existing major problems , some policy recommendations were put forward including clarify the funding criteria and strengthen the premarital healthcare publicity in order to promote the sustainable development of premarital healthcare services .

Objective To improve the design of the fluid supplementation system of Johnson & Johnson automatic blood typing and cross matching instrument to optimize its working flow.Methods Two polyethylene funnels were placed at the cabinet door to execute drainage,which had the height being 14.6 cm,diameter of the wide mouth being 15 cm,protective lip made of hardboard and volume being 700 ml.Each funnel was connected with a 21-mm-diameter drainage tube whose end was put into a flask full of 0.9％ saline or distilled water respectively.Results The velocity was enhanced efficiently for fluid supplementationn,surface pollution due to liquid splash was avoided,and working comfort and efficiency were increased greatly.Conclusion The improved fluid supplementation system gains advantages in low cost,no pollution and convenience,and thus is worthy promoting practically.

Background Age-related macular degeneration (AMD) is a heritable,progressive degenerative disorder that triggers central visual impairment.Research demonstrated that the single nucleotide polymorphisms (SNPs) of vascular endothelial growth factor 1 (VEGFR1) gene is associated with AMD in different population.However,the results varied among diversified ethnic origin composition and distinct regions.Objective This study was to investigate the associations between the SNPs of VEGFR1 genetic variants along with smoking exposure and the risk of AMD in Hui and Han ethnics in the Ningxia population in China.Methods A case-control study was conducted.Four hundreds and thirty-two AMD patients including 325 Han ethnic patients and 107 Hui ethnic patients were recruited from March 2011 to June 2015,and 906 ethnicity-and gender-matched age-related cataract patients were contemporaneously recruited as control group,including 698 Han ethnic patients and 208 Hui ethnic patients.Periphery blood sample of 5 ml was collected from the subjects and genomic DNA was prepared.Eight tagging SNPs loci were acquired to cover rs2281827,rs3936415,rs7337610,rs7981680,rs9554320,rs9554322,rs9582036 and rs9943922,and the genotypes of SNPs were detected by using MassARRAYTM time-of-flight mass spectrometry system.Chi-square test and multi-factor Logistic regression analysis were utilized to estimate the discrepancy of allele frequency and genotype distribution in Hui and Han AMD patients.Moreover,the correlation of AMD with smoking and age statue were further analyzed.This study protocol complied with Helsinki Declaration and was approved by Ethic Committee of Ningxia Eye Hospital.Written informed consent was obtained before any relevant medical examination.Results There were significant differences in the age between AMD group and control group in both Han and Hui ethnicity (Han:P =0.000;Hui:P =0.009).The smoking exposure was significantly different between AMD group and control group in Han ethnicity (P =0.000),and smoking was the independent risk factor of AMD disease in Han ethnicity of N ingxia region (odds ratio [OR] =2.622,95％ confidence interval [CI]:1.899-3.619).The allele frequencies of SNPs were not significantly different in the AMD patients between Han and Hui ethnicity (all at P＞0.05).However,the allele frequencies and genotype distribution of rs7337610 and rs9554322 SNPs were significantly different between the AMD group and control group in both Han and Hui ethnicity (all at P=0.00).The genotype distribution of rs9582036 and rs9943922 SNPs was significantly different between the AMD group and control group in Han ethnicity (P=0.02,0.00).Allelic G of rs7337610 was the protective factor of AMD disease in Han and Hui ethnieity (OR=0.354,95％ CI:0.288-0.435;OR=0.446,95％ CI:0.315-0.632),while allelic C of rs9554322 was the risk factor of AMD disease in Han and Hui ethnicity (OR=1.671,95％ C1:1.234-2.262;OR=3.661,95％ CI:2.156-6.218).Allelic A of rs9582036 was the risk factor of AMD disease in Han ethnicity (OR =1.477,95％ CI:1.124-1.940).Conclusions Smoking is the independent risk component for Han population with AMD.Of the eight SNPs tagged,the genotypes and alleles of rs9554322 and rs7337610 seems to confer susceptibility to AMD in both Han and Hui ethnicity,the genotypes and alleles of rs9582036 and rs9943922 confer susceptibility to AMD in only Han ethnicity.
