Disclosure of suboptimal health status through traditional Chinese medicine-based body constitution and pulse patterns

ObjectivesSuboptimal health status (SHS) is a dynamic state wherein people have not been diagnosed with a disease but tend to develop diseases. People with SHS often experience fatigue and other nonspecific symptoms, which are related to a deviated body constitution in traditional Chinese medicine (TCM). However, the correlation between TCM constitution and SHS has not been adequately investigated. Furthermore, no study has explored the radial pulse analysis—an assistive objective indicator of TCM constitution—in healthy people and people with SHS.DesignA cross-sectional study.Settings/LocationCenter for Traditional Medicine, Taipei Veterans General Hospital, Taiwan.SubjectsSixty-six adults (27 healthy participants and 39 participants with SHS) who were aged 20–39 years.Outcome MeasuresThe body constitution questionnaire (BCQ) scores, suboptimal health status questionnaire-25 (SHSQ-25) scores, and radial pulse waves detected using sphygmography were recorded. Pulse wave analyses are presented as the ratio of frequency below 10 Hz to that above 10 Hz (SER10), which represent energy changes in organ blood flow.ResultsParticipants with SHS had significantly higher Yang-Xu, Yin-Xu, and stasis scores of BCQ compared with healthy participants. The SHSQ-25 scores of the participants with SHS were moderately correlated with their Yang-Xu, Yin-Xu, and stasis scores (r = 0.65, 0.66, and 0.72, respectively; all p < 0.001), but weak correlations were discovered for healthy participants. The participants with SHS had significantly higher SER10 at the left guan (the “liver” system in TCM) than did the healthy participants.ConclusionsSHS is moderately correlated with TCM-based constitution and those with SHS had increased SER10 at the leftguan of the radial pulse.

Reliability and validity of the Tibetan medicine constitution scale: a cross-sectional study of the general population in Beijing,China

Background:The constitutional theory is an important aspect of Tibetan medicine,however a quantitative measurement tool for constitution identification still does not exist.The objective of this study is to evaluate the reliability and validity of a Tibetan medicine constitution scale(TMCS)that consists of three sub-scales and 31 items.Methods:From June to July 2019,622 people from the general population in Beijing,China,aged 18 to 60 were investigated.We employed Cronbach’s alpha(α),split-half reliability,and test-retest reliability to determine the reliability of the scale.The content validity and contract validity of the TMCS were evaluated using factor analysis and correlation analysis based on Tibetan medicine theory.The items were screened according to the reliability test results.Results:After the items were screened,22 items remained in the scale.The Cronbach’s alpha value for the internal consistency reliability of the TMCS was 0.754(95%confidence interval(CI):0.700–0.761).The correlation coefficient for the two-week test-retest of the total score was 0.726(95%CI:0.571–0.834).The split-half coefficient was 0.689(95%CI:0.640–0.734).The scale can be explained by eight potential factors,including morphological structure,physiological function,personality,adaptability,etc.The body mass index was negatively correlated with the score of the sub-rlung scale(r=−0.376),slightly positively correlated with the sub-mkhris pa scale(r=0.099),and positively correlated with the sub-bad kan scale(r=0.362).Conclusion:The TMCS is a reliable and valid instrument that can be used to assess the body constitution of the general population in Beijing,China.Future studies are needed to explore the differences in biological characteristics among the constitutional types and the association between constitution and disease.     

不同年龄段飞行员体质特征的研究

目的 了解飞行员的身体形态、机能和运动能力特征,指导飞行员的体能训练. 方法 采用智能化体质测试系统,测试31 2名健康男性现役歼(强)击机飞行员(年龄23～49岁)的身高、体重、BMI、血压、肺活量、台阶试验、握力、仰卧起坐、俯卧撑等14项指标,以间隔5岁为1组分为6个年龄段进行分析对比. 结果 随着年龄增长飞行员身高呈降低趋势(F=3.012,P＜0.05),体重和BMI逐渐增加(F=7.601、12.581,P＜0.01),30岁以上年龄段飞行员BMI均值＞24 kg/m2.血压随年龄增大有增高趋势,但均值在正常范围内;肺活量随年龄增大而降低(F=8.315,P＜0.01);各年龄段台阶试验指数有降低趋势(F=2.578,P＜0.05).20～29岁年龄段飞行员的纵跳高度、俯卧撑和仰卧起坐次数等明显高于35～49岁年龄段(P＜0.05或P＜0.01);随年龄增大,飞行员的闭眼单脚站立时间逐渐缩短(F=9.183,P＜0.01),选择反应时和5×10 m折返跑时间逐渐延长(F=5.985、15.965,P＜0.01),但坐位体前屈距离和握力变化不明显. 结论 30岁以上年龄段的飞行员BMI均值达到普通人群确定的超重范围.20～29岁年龄段飞行员运动能力指标明显高于35～49岁年龄段.本组飞行员各年龄段机能指标、运动能力指标均值高于普通人群,但部分指标低于我军飞行人员的相关标准.     

高血压与中医体质相关性的荟萃分析＊

目的 通过Meta分析研究高血压与中医体质的相关性，为高血压防治提供依据。方法 通过检索国内文献库，纳入符合要求的高血压与中医体质相关性文献，提取原始文献资料并评价研究的质量；以RevMan 5.3软件进行异质性检验和Meta分析，并通过亚组分析探索异质性来源，以漏斗图评估发表偏倚。结果 共有10篇文献符合纳入标准，涉及高血压病人4 401例，对照组7 934例，全部为横断面研究。痰湿质（OR = 2.24，95%CI：1.77 - 2.83，P < 0.001）、阴虚质（OR = 1.28，95%CI：1.13 - 1.45，P < 0.001）、气虚质（OR = 1.21，95%CI：1.06 - 1.37，P = 0.005）、血瘀质（OR = 1.24，95%CI：1.06 - 1.46，P = 0.007）是高血压人群更易出现的体质类型；而平和质是对照组更易出现的体质类型（OR = 0.56，95%CI：0.51 - 0.61，P < 0.001）；阳虚质、气郁质、湿热质、特禀质在高血压人群和非高血压人群的分布无明显统计学差异。亚组分析显示是否明确纳入既往诊断的高血压和研究质量是异质性主要来源；目测漏斗图未发现明显发表性偏倚。结论 痰湿质、阴虚质、气虚质、血瘀质是高血压易感体质，平和质是保护体质，但由于纳入研究质量不佳，且存在设计缺陷，无法说明中医体质与高血压发生的因果关系，结论需谨慎对待。     

Pre-differentiated human committed T-lymphoid progenitors promote peripheral T-cell re-constitution after stem cell transplantation in immunodeficient mice

T-cell re-constitution after allogeneic stem cell transplantation (alloSCT) is often dampened by the slow differentiation of human peripheral blood CD34(+) (huCD34(+) ) hematopoietic stem cells (HSCs) into mature T cells. This process may be accelerated by the co-transfer of in vitro-pre-differentiated committed T/NK-lymphoid progenitors (CTLPs). Here, we analysed the developmental potential of huCD34(+) HSCs compared with CTLPs from a third-party donor in a murine NOD-scid IL2Rγ(null) model of humanised chimeric haematopoiesis. CTLPs (CD34(+) lin(-) CD45RA(+) CD7(+) ) could be generated in vitro within 10 days upon co-culture of huCD34(+) or cord blood CD34(+) (CB-CD34) HSCs on murine OP9/N-DLL-1 stroma cells but not in a novel 3-D cell-culture matrix with DLL-1(low) human stroma cells. In both in vitro systems, huCD34(+) and CB-CD34(+) HSCs did not give rise to mature T cells. Upon transfer into 6-wk-old immune-deficient mice, CTLPs alone did not engraft. However, transplantation of CTLPs together with huCD34(+) HSCs resulted in rapid T-cell engraftment in spleen, bone marrow and thymus at day 28. Strikingly, at this early time point mature T cells originated exclusively from CTLPs, whereas descendants of huCD34(+) HSCs still expressed a T-cell-precursor phenotype (CD7(+) CD5(+) CD1a(+/-) ). This strategy to enhance early T-cell re-constitution with ex vivo-pre-differentiated T-lymphoid progenitors could bridge the gap until full T-cell recovery in severely immunocompromised patients after allogeneic stem cell transplantation.
