Ba.kground: Dia.etic nephropa.hy is the lea.ing ca.se of end-sta.e chronic kidney disea.e with poor prognosis in resource-limited settings. This study a.med to determine fa.tors a.socia.ed with morta.ity in pa.ients sta.ting dia.ysis trea.ment for end-sta.e chronic rena. disea.e in a. emergency context.

In this work, a.systema.ic a.proa.h is presented to obta.n the input-output equa.ions of a.single loop 4-ba. spa.ia. mecha.isms. The dia.ytic method a.ong with Dena.it-Ha.tenberg pa.a.eters ca. be used to obta.n these equa.ions efficiently. a.genetic a.gorithm （ga） ha. been used to solve the problem of spa.ia. mecha.isms synthesis. Two types of mecha.isms, e.g., RSCR a.d RSPC （R： revolute; S： spherica.; C： cylindrica.; P： prisma.ic）, ha.e illustra.ed the a.plica.ion of the ga to solve the problem of function genera.ion a.d pa.h genera.ion. In some ca.es, the ga method becomes tra.ped in a.loca. minimum. a.combined ga-fuzzy logic （ga-FL） method is then used to improve the fina. result. The results show tha. gas, combined with a. a.equa.e description of the mecha.ism, a.e well suited for spa.ia. mecha.ism synthesis problems a.d ha.e neither difficulties inherent to the choice of the initia. fea.ible guess, nor a.problem of convergence, a. it is the ca.e for deterministic methods.

唾液是一种微酸性口腔液,主要由水构成,含有少量无机离子和丰富的蛋白质,这些成分使其具有特殊的流变学和生物学性质,赋予其丰富的生物学功能,对维持口腔及全身健康起重要作用。唾液减少或成分改变会导致口干症,易引发一系列口腔健康失衡,如口腔灼热,味觉改变,言语、咀嚼和吞咽困难,还会增加患龋病和牙周病等风险,严重影响患者生活质量。口干症的患病率约为20%,且患病率随年龄增长而增加,75岁以上老年人群的患病率约为50%。随着老龄化人口的增加,口干及其并发症已引发不可忽视的健康负担。人工唾液是开发用于模仿天然唾液生物学性质和功能的口腔护理产品,是对症治疗口干症的重要方法之一。安全、有效的人工唾液,对维护老年人口腔健康具有积极作用和市场前景。开发人工唾液首先要全面认识天然唾液的特性。本文系统介绍了天然唾液的成分及生物学功能,并详细描述了人工唾液的流变学行为、摩擦学性质、生物学特性以及临床应用性能等内容,以期为新型人工唾液的开发提供帮助。

为进一步提高芫根产量和种植芫根的经济效益,选取玉树藏族自治州地方品种玉树芫根为材料,以不施肥(CK)为对照,研究不同配比的N、P、K肥料对芫根根长、根粗、鲜质量的影响,采用隶属函数法综合评价其农艺性状,并对各个施肥处理获得的经济效益进行比较。结果表明,NP10处理下根长最长,为5.53 cm,N20处理下对玉树芫根根粗和根鲜质量促进效果最好,分别为9.43 cm和299.33 g。在NP10处理下,根形指数达到0.69,接近圆形,商品性较好。综合评价结果表明,N20(每667 m^(2)追施20 kg尿素)隶属函数值最高,达到0.84,产生的经济效益为1006.39元。综上所述,每667 m^(2)施用20 kg尿素提高了玉树芫根的产量及经济效益,研究结果为后续芫根高产种植提供了合理的施肥方案。
