Genetic polymorphisms of new 22 autosomal STR loci in the Mongolian ethnic group

The Microreader™ 23SP ID System is a novel STR kit, but there are no Mongolian data related to this kit. In this study, allelic frequencies and forensic parameters were obtained from 505 unrelated healthy Mongolians. These samples were amplified using the kit. The dataset successfully passed quality control after being submitted to STRidER (STRidER dataset reference STR000198). A total of 264 alleles were observed, with corresponding allelic frequencies ranged from 0.001 to 0.378. The combined power of discrimination (CPD) and combined probability of exclusion (CPE) of the 22 autosomal STR loci were 0.999999999999999999999999999217318 and 0.999999999776042, respectively. Furthermore, population differentiation comparisons involving previously reported groups were conducted.

     

二类疫苗纳入深圳市社会医疗保险研究概述

目的为推广二类疫苗纳入社会医疗保险支付范围的卫生策略提供决策信息。方法综合运用问卷调查、专题访谈、专家咨询、基金风险测算等方法,研究深圳市二类疫苗纳入社会医疗保险支付范围的具体可操作政策。结果90%的社区居民认为将二类疫苗纳入社会医疗保险支付有必要;医务人员对社保支付二类疫苗基本持支持态度;二类疫苗纳入社保支付具有显著的经济效益;二类疫苗纳入社保支付的基金风险具有可控性。结论二类疫苗有必要纳入深圳市社会医疗保险支付,但在实施和技术操作方面仍然存一定的局限和挑战。     

生理性海水鼻喷剂治疗儿童鼻窦炎疗效观察

目的:探讨生理性海水鼻喷剂治疗小儿鼻窦炎的临床疗效。方法:将临床确诊的鼻窦炎患儿120例随机分为观察组和对照组各60例,对照组使用抗生素、黏液促排剂以及鼻渊通窍颗粒治疗,观察组在对照组治疗基础上配合使用生理性海水鼻喷剂治疗,两组均连续治疗6周,期间停用其他一切可影响鼻通气的药物。结果:治疗后观察组总有效率为93.33%,高于对照组的78.33%(P<0.05);VAS 总分、Lund-Kennedy 总分均低于对照组(P均<0.05)。结论:生理性海水鼻喷剂配合常规药物治疗可有效提高儿童鼻窦炎的疗效,减少不良反应的发生。     

充血性心力衰竭中医病机演变规律认识

充血性心力衰竭(CHF)中医证治规律的研究历经多年,目前仍在继续进行当中,其病机演变规律作为其中关键部分,目前仍没有获得统一认识.在近年的一些中医文献中,分型也多不一致,少则2型,多则6型,其主要原因则是由于辨证标准不同,选取的症状和体征往往带有很强的主观性,从而使其证型不规范不统一,各研究结果就不能互相印证、解释和归纳,不能有效地指导临床.     

Electrophysiologic and chemoreceptive characteristics of pontomedullary and thalamic neurons during the process of ontogenetic development]

The background and evoked activity of reticular units in the medulla, pons and ventrobasal complex of the thalamus was studied on cat's fetuses and kittens 54-65 and 1-60 days old, respectively. 63% (pons) and 92% (medulla) of spontaneously active cells were recorded in the fetuses. The highest percentage of evoked responses (60% in the fetuses) was observed upon stimulation of the tongue. Repeated application of stimuli facilitated the firing during the interstimulus intervals, especially during the early developmental stages. Sensitivity to transmitters in the fetuses was maximal to noradrenalin (87%) and glutamate (70%) and minimal to acetylcholine (43%). With development of the animal the number of adrenosensitive units decreased, that of the cholinosensitive increased, and the sensitivity to glutamate remained at the same level. A conclusion is made that the synaptic processes at early developmental stages are mainly of adrenergic and glutamate nature.     

The effect of sectioning the lingual nerve on the morphometric characteristics of the reticular nuclei in the brain stem in the kitten]

Three subpopulations of Golgi-stained neurons of the brainstem reticular nuclei have been studied by the method of computer morphometry in 30-day old kittens. 23 parameter of the neuronal geometry were analyzed after uni-and bilateral lingual nerve section 5-7 days after birth. All of cells display statistically valid changes in some parameters, typically differing in every group: for reticular neurons--free distribution of dendrite endings in the dendritic field; for arborescent ones--the length of dendritic segments; for giant multipolar neurons--distribution of foci of maximal dendrite branching in the dendritic field. Unilateral lingual nerve section gives more pronounced quantitative deviations from the normal state, than bilateral one.     

2456例唾液腺肿瘤临床病理分析

目的探讨唾液腺肿瘤的发病、病理类型等临床特点。方法收集中山大学孙逸仙纪念医院口腔颌面外科1973年1月至2018年12月间确诊的唾液腺肿瘤病例2456例患者的相关资料,回顾分析其性别、年龄、病理类型、发病部位、良恶性构成比等特点。结果46年间收治的唾液腺肿瘤患者2456例,女性比例占41.9%,男性占58.1%,40~60岁年龄段为发病高峰,其中良性肿瘤1863例(75.9%),恶性肿瘤593例(24.1%),良恶性之比为3.1∶1。良性肿瘤构成比前2位是多形性腺瘤(58.7%)、Warthin瘤(33.6%),恶性肿瘤构成比前2位是黏液表皮样癌(27.7%)、腺样囊性癌(26.1%)。最常见的良性肿瘤多形性腺瘤的好发部位是腮腺、腭部、颌下腺,而恶性肿瘤中粘液表皮样癌则常见于腮腺和腭部的小唾液腺。本组资料中唾液腺肿瘤发病呈逐年递增的趋势,近10年病例占总病例数的53.3%。结论唾液腺肿瘤病人数量逐年增加;唾液腺肿瘤的总发生率男性高于女性;大唾液腺以良性肿瘤为主,小唾液腺恶性肿瘤多见;多形性腺瘤、Warthin瘤、黏液表皮样癌最常见;40~60岁是唾液腺良、恶性肿瘤高发年龄段。     

Quantitative morphologic characteristics of neurons of the sensory nuclei of the trigeminal nerve developing after partial deafferentation

Five types of neurons were studied in the sensory nuclei of the trigeminal nerve stained by the Golgi method in kittens aged 30 days with bilateral transection of the lingual branches of trigeminal nerve made on the fifth postnatal day. Partial deafferentation resulted in changes of dendrite apparatus of reticular, arborescent and bushy neurons (68.61 and 48% of neurons changed). Short-dendritic cells changed slightly. The multipolar giant neurons underwent practically no changes. All the changes could be divided into two groups: destructive changes and constructive changes. The destructive changes consisted in the decrease of cell body sizes, number, length and ramification of dendrites and constructive changes--in the increase of these parameters. Various types of trigeminal neurons responded to deafferentiation in different ways. Bushy neurons displayed mainly destructive changes and reticular and arborescent neurons--both destructive and constructive ones.
