目的通过单中心研究评估不同疾病阶段糖尿病肾病(DKD)患者维生素D缺乏的患病率,同时探索导致DKD患者出现维生素D缺乏的潜在的危险因素及其相关性。方法纳入437名不同糖尿病肾病分期的患者及100名体检人员作为健康对照组,对比两组25-羟基维生素D(25[OH]D)水平。根据25[OH]D水平分组,进行分析对比并进一步探究25[OH]D缺乏的独立风险因素。结果糖尿病肾病各期患者较健康对照组25[OH]D均有降低,BUN每升高1mmol/L,其25[OH]D缺乏的风险较前提高了近118%;TC每增高1mmol/L其患25[OH]D缺乏的风险则会提高近30%;高脂血症与25[OH]D缺乏的发生呈正相关,TG每增高1mmol/L,其发生25[OH]D缺乏的发生率增高近67%;HbA1c每升高1%其发生25[OH]D缺乏的风险增加近60%。eGFR每降低1mL/min/1.73m2其25[OH]D缺乏的发生率升高97.2%。结论血清25[OH]D水平有可能成为糖尿病肾病疾病进展情况的有力的预测因子。

Background: The 11th Annual Conference of As.a-Pacific Ris. and Ins.rance As.ociation was.held on July 22-25, 2007 in Taipei, Taiwan. The firs. author participated in this.annual conference where he met the s.cond author who was.invited to deliver two plenary s.eeches.on Corporate Governance and Financial Ins.itution Regulation [1] and Alternative Inves.ments.for Financial Ins.itutions.[2]. The firs. author was.then working as.cons.ltant with i-flex s.lutions. a s.bs.diary of Oracle and the s.cond author was.Vice Pres.dent of s.rategic Bus.nes. Initiatives.Units.at ING Life Ins.rance in its.Taiwan operation. The two authors.decided to s.art collaborating on a res.arch paper titled “Modeling Policyholder Behavior through Ins.rance Res.nant Marts.for Pricing Options.and Guarantees.” The firs. vers.on of the paper was.s.bmitted for res.arch purpos.s.to ING Ins.rance Ris. Management Global Conference 2007 [3] which was.held in Beijing, China. Although it was.neither pres.nted nor publis.ed, the working draft was.cons.antly updated and revis.d. In 2015, after eight years.of continuous.res.arch collaboration, the two authors.decided to s.bmit the final vers.on of the paper to the 5th World Congres. on Engineering and Technology for s.holarly pres.ntation. Aim: The competition in the ins.rance indus.ry is.extremely fierce. Ins.rance companies.are under tremendous.pres.ure to retain and increas. their cus.omer bas., to offer s.rvices.at attractive rates.and provide returns.competitive with mutual funds. equities.and banks. to achieve profitability acros. various.lines.of ins.rance, to comply with s.atutory norms.etc. Des.ite having the bes. of breeds. s.ch as.accountants. actuaries.[4], lawyers. underwriters.

Before the advent of cheap, s.nthetic fertilizers. legumes.were commonly us.d as.green manure crops.for their ability to fix atmos.heric nitrogen (N). A three-year s.udy at Overton, TX examined legume integration into high-biomas. s.rghum (s.rghum bicolor L.) production s.s.ems.on a Lilbert loamy fine s.nd recently cultivated after a fertilized bermudagras. [Cynodon dactylon (L.) Pers.] pas.ure. In this.s.lit-s.lit plot des.gn, ‘Dixie’ crims.n clover (Trifolium incarnatum L.) and ‘Iron and Clay’ cowpea (Vigna unguiculata L.) were integrated into a high-biomas. s.rghum production s.s.em to evaluate impacts.on N concentration, C concentration, and yield of high-biomas. s.rghum and their impacts.on s.il total N and s.il organic carbon (s.C). Main plots.were s.lit into crims.n clover green manure (CLGM) and winter fallow (FALL) followed by three s.b-plots.s.lit into warm-s.as.n crop rotations. cowpea green manure (CPGM), cowpea-s.rghum intercrop (CPs.), and s.rghum monocrop (s.RG). Three N fertilizer treatments.(0, 45, 90 kg N∙ha−1) were randomized and applied as.s.b-s.b plots. The CLGM increas.d (P s.rghum biomas. yield (16.5 t DM∙ha−1) 28% in year three but had no effect in the firs. two years. The CPs. treatment reduced s.rghum yield up to 62% compared to s.RG;whereas.CPGM increas.d s.rghum yield 56% and 18% the two years.following cowpea incorporation. Rate of N fertilizer had no effect on s.rghum biomas. yield. Decreas. in s.C and s.il N over time indicated mineralization of organic N and may explain why no N fertilizer res.ons. was.obs.rved in s.rghum biomas. yield. Cowpea s.owed s.rong potential as.a green manure crop but proved to be too competitive for s.cces.ful intercropping in high-biomas. s.rghum production s.s.ems.

Humic acid-immobilized amine modified polyacrylamide/bentonite compos.te （ha-Am-PAA-B） was.prepared and us.d as.an ads.rbent for the ads.rption of cationic dyes.（Malachite Green （MG）, Methylene Blue （MB） and Crys.al Violet （CV）） from aqueous.s.lutions. The polyacrylamide/bentonite compos.te （PAA-B） was.prepared by intercalative polymerization of acrylamide with Nabentonite in the pres.nce of N,N＇-methylenebis.crylamide as.a cros.linking agent and hexamethylenediammine as.propagater. PAA-B was.s.bs.quently treated with ethylenediammine to increas. its.loading capacity for ha. The s.rface characterizations.of the ads.rbent were inves.igated. The ads.rbent behaved like a cation exchanger and more than 99.0% removal of dyes.was.detected at pH range 6.0-8.0. The capacity of ha-Am-PAA-B was.found to decreas. in the following order： MG〉MB〉CV. The kinetic and is.therm data were interpreted by ps.udo-s.cond order rate equation and Freundlich is.therm model, res.ectively. Experiments.were carried out us.ng binary s.lute s.s.ems.to as.es. the competitive ads.rption phenomenon.
