基于仝小林院士脏腑风湿理论探讨新型冠状病毒肺炎康复期的中药治疗

仝小林院士将新型冠状病毒肺炎定名为"寒湿疫"，并以此理论为基础制定了初期、中期、重症期及恢复期的中医治疗方案，同时基于仝院士学术理论体系中的"脏腑风湿"理论，根据恢复期 "余毒未清，正虚邪恋"的病机特点，探讨其符合具备脏腑风湿行成3个基本要素：即外受寒湿裹挟戾气为必要外因；脏腑内虚为重要基础；邪疫伏留胶着，正邪交争为致病关键。故在辨证施治中可应用脏腑风湿理论以调理脾胃，化湿透邪，补益肺脾，顾护阳气，养阴生津。     

CD44基因多态性与宫颈癌及非小细胞肺癌的相关性

背景与目的：CD44分子是众多肿瘤细胞的标志分子，其表达水平与肿瘤细胞的恶性程度有关。该研究探讨CD44基因中的单核苷酸多态性（single nucleotide polymorphism，SNP）位点与云南汉族人群宫颈癌和非小细胞肺癌（nonsmall cell lung cancer，NSCLC）易感性的相关性。方法：选取了CD44基因中的两个SNP位点rs13347和rs8193，采用TagMan基因分型的方法，分析这两个多态性位点在497例宫颈癌患者和500例健康对照个体以及483例NSCLC患者和471例健康对照个体中的分布特征，并分析CD44基因中的多态性位点与云南汉族人群宫颈癌和NSCLC的相关性。结果：rs13347和rs8193位点等位基因和基因型在宫颈癌组和对照组中的分布频率的差异无统计学意义（P>0.05）。而在NSCLC组和对照组的比较中：rs13347和rs8193位点等位基因在NSCLC组和对照组中的分布频率的差异有统计学意义（P=0.020和P=0.004）；这两个位点基因型在NSCLC组和对照组中分布频率的差异有统计学意义（P=0.027和P=0.020）；其中rs13347位点等位基因C在NSCLC组中的分布频率显著高于对照组，可能是NSCLC发生的风险因素（OR=1.250，95% CI：1.035～1.509），rs8193位点等位基因C在对照组中的分布频率显著高于NSCLC组，可能是NSCLC发生的保护性因素（OR=0.768，95%CI：0.641～0.921）。单倍型分析结果显示，rs13347C-rs8193T和rs13347T-rs8193C在NSCLC组和对照组中的分布频率差异有统计学意义（P=0.003和0.022）；该结果说明单倍型rs13347C-rs8193T可能是云南汉族人群NSCLC发生的风险性因素（OR=1.316，95%CI：1.096～1.579）。结论：CD44基因中的两个SNP位点rs13347和rs8193可能与云南汉族人群宫颈癌发病风险无关，而可能与云南汉族人群NSCLC具有相关性。     

Racial matching and adolescent self-disclosure of substance use and mental health symptoms

Obtaining accurate assessment data from adolescents in treatment aids clinical decision making and facilitates more accurate outcome evaluations. However, findings could be biased due to underreported substance use and mental health symptoms. This article compares self-reports of youth in non-White matched client–assessor dyads and those in nonmatched dyads. There were no differences on self-reported substance use, but matched youth reported significantly fewer attention deficit/hyperactivity disorder symptoms versus the comparison group. One possible reason for these findings is the effect of in-group stereotype threat. Future studies should examine the potential effect that in-group stereotyping and perceived racism have on the therapeutic relationship.     

Genetic variation of 17 autosomal STR loci in the Lahu population from Yunnan and phylogenetic structure exploration among 28 populations

This study evaluated the genetic variation of 17 autosomal short tandem repeat (STR) loci included in the PowerPlex® 18D Kit. Samples of 562 unrelated healthy Lahu individuals living in Yunnan Province in southwestern China were investigated. The data were analyzed to provide information on allele frequencies and other statistical parameters relevant to the forensic population. Of the 17 loci, 16 reached the Hardy–Weinberg equilibrium after Bonferroni correction. A total of 176 alleles were identified in 17 STR loci, and allele frequencies ranged from 0.000 890 to 0.578 292. The combined discrimination power (CPD) and probability of excluding paternity (CPE) of the 17 STR loci were 0.999 999 999 999 999 999 489 and 0.999 998 301 753 122. The genetic relationships among 28 populations were also estimated.     

石家庄地区汉族人群DIS80(pMCT118)位点VNTR基因频率分布调查

本文采用ＰＣＲ技术对石家庄地区２１６名无关个体ＤＩＳ８０（ｐＭＣＴ１１８）位点扩增片段长度多态性的等位基因频率进行调查。ＰＣＲ扩增产物采用聚丙烯酰胺凝胶电泳分型及溴化乙锭染色，共检出７０种基因型，２５个等位基因，其中以１８、２４、３０三个等位基因频率最高。将本文结果与日本人群在ＤＩＳ８０（ｐＭＣＴ１１８）位点多态性结果进行比较，石家庄地区汉族人群ＤＩＳ８０（ｐＭＣＴ１１８）位点基因频率分布符合ＨａｒｄｙＷｅｉｎｂｅｒｇ平衡定律，该位点非父排除率为０．７１，个体识别率为０．９，杂合度为０．８５。     

EARLY EDUCATION AND CHILDREN WITH SPECIAL NEEDS

Changing issues in the field of preschool education will be discussed, set in the context of two of my studies which have been concerned with children with special needs in 'ordinary' preschool education, one 'pre-Warnock' in Scotland, and the other 'post-Warnock' in the West Midlands. The concept of special needs will then be widened to include children for whom English is a second language, and also gifted children. Finally, the discussion is extended to early education rather than preschool education with a discussion of the dangers of treating preschool education in isolation.     

辽宁满族和汉族指纹白线正常值分析

本文报告了辽宁满族和汉族人指纹白线的调查结果。满族和汉族人的指纹白线出现率分别是7.14％和31.73％。满族人的指纹白线出现率低于汉族、维吾尔族、德国人、波兰人和美国白人。作者注意到满族人的指纹白线不存在左右手间和性别间的差异,而汉族人性别间差异显著。十指均有白线频率为1.91％(满族)和10.5％(汉族)。十指均有白线的白线平均数满族为39.3±6.6,汉族为35.5±10.6。五指中指纹白线出现率从高到低的顺序在满族为Ⅰ、Ⅳ、Ⅲ、Ⅱ、Ⅴ,在汉族为Ⅳ、Ⅲ、Ⅱ、Ⅰ、Ⅴ。存在民族间的差异。     

上海地区汉族优秀游泳运动员ACE基因I/D多态性研究

目的:探讨上海地区汉族不同水平优秀游泳运动员ACE(血管紧张素转化酶)基因I/D多态性的分布特点。方法:采用PCR方法,对上海地区85名汉族优秀游泳运动员和90名汉族普通人的ACE基因I/D多态性进行检测。结果显示,上海地区汉族优秀游泳运动员的ACE基因的基因型和等位基因频率与上海和成都地区汉族普通人无明显差异(P>0.05);上海地区汉族游泳运动员和普通人以及成都地区汉族普通人的基因型和等位基因频率均与高加索人群存在高度显著性差异(P<0.0001),表现出明显的种族差异性。7名上海地区汉族国际健将ACE基因均为II型,运动水平越高的组别,II基因型和I等位基因频率越高,提示具有II基因型或I等位基因频率高的运动员经过多年运动训练,具有成为优秀运动员的可能,特别是II基因型的运动员可能性更大。
