基于文献的老年人群常见证候分布特征研究＊

目的 了解我国老年人中医证候分布特征，为中医药辨治老年人提供参考依据。方法 系统检索中国知识基础设施（CNKI）、中文科技期刊数据库（CCD）、万方数据资源系统数据库（CSPD），纳入研究对象为老年人的临床流行病学调查研究文献，对其调查目的、调查疾病及调查结果等进行描述统计。结果 ①最终纳入168篇文献，其中2010至2020年之间发表138篇（82.14%）；调查地区涵盖全国28个省市自治区，共纳入43948例老年人，累计覆盖340个研究中心；②主要研究结果显示，老年人中医证候阴虚阳亢证（10.05%）>血瘀证（9.5%）>痰浊（湿）证（8.91%）>阴阳两虚证（4.98%）>痰瘀互结证（4.96%）；单元证分布阴虚证（14.70%）>痰证（11.22%）>气虚证（7.15%）>肾虚证（4.72%）>血瘀证（4.18%）；涉及病变脏腑肾>肝>脾>肺>心。结论 根据统计结果，可以看出老年人证候分布虚证多于实证，虚证中又以阴虚证、气虚证最为多见，实证常见血瘀证、痰浊（湿）证等，且多见痰瘀互结证；老年人五脏皆损，其中又以肾、肝、脾功能失调最为突出。     

Nationwide outcomes of newborns with rectosigmoid versus long-segment Hirschsprung disease

PurposeHirschsprung Disease (HD) is a common congenital intestinal disorder. While aganglionosis most commonly affects the rectosigmoid colon (rectosigmoid HD), outcomes for patients in which aganglionosis extends to more proximal segments (long-segment HD) remain understudied. This study sought to compare postoperative outcomes among newborns with rectosigmoid and long-segment HD.MethodsThe Nationwide Readmission Database was queried from 2016 to 2018 for newborns with HD. Newborns were stratified into those with rectosigmoid or long-segment HD. Those who received no rectal biopsy or pull-through procedure during their newborn hospitalization were excluded. A propensity score-matched analysis (PSMA) of newborns with either type of HD was constructed utilizing 17 covariates including demographics, comorbidities, and congenital-perinatal conditions.ResultsThere were 1280 newborns identified with HD (82% rectosigmoid HD, 18% long-segment HD). Patients with rectosigmoid HD had higher rates of laparoscopic resections (35% vs. 12%) and less frequently received a concomitant ostomy (14% vs. 84%), both p < 0.001. Patients with long-segment HD were more likely to have a delayed diagnosis (12% vs. 5%) and require multiple bowel operations (19% vs. 4%), both p < 0.001. They experienced higher rates of complications, including small bowel obstructions (10% vs. 1%), infections (45% vs. 20%), and Hirschsprung-associated enterocolitis (11% vs. 5%), all p < 0.001. After PSMA, newborns with long-segment HD were found to have a longer length of stay and higher hospitalization costs.ConclusionNewborns with long-segment HD experience significant delays in diagnosis, surgery, and complications compared to those with rectosigmoid HD. This information should be utilized to improve healthcare delivery for this patient population.Type of StudyRetrospective comparative study.Level of EvidenceIII.     

中医药对淋巴管新生与回流功能的作用研究进展＊

淋巴管作为循环系统的重要组成部分之一，具有调节机体体液稳态，协助免疫监视和肠道脂质吸收等重要作用。淋巴管新生是机体生理和病理过程中维持脉管系统结构和功能正常的重要手段，淋巴管新生调控对于防治肿瘤、心血管等诸多疾病有着潜在的临床转化意义；淋巴回流功能则与关节炎症等疾病发病机制关系密切。在循环系统中，相较于中医药调控血管相关疾病的发病机制已取得很大进展，近年来对于淋巴管的研究则明显相对滞后。本文从中医药作用于淋巴管新生及回流功能角度对这一领域的研究进展作一综述，以期为临床上中医药治疗相关疾病提供新的思路与方法。     

清热透邪法在新冠肺炎中的应用＊

目前新冠肺炎中医归属于“疫病”“瘟疫”范畴。其病因为疫戾邪气从口鼻而入，病理特点主要涉及湿、热、毒、瘀、浊、虚6个方面，但对于其病邪的性质，中医学界尚无完全统一认识。呈现百花齐放百家争鸣状态，此次疫病，王灿晖教授认为部分患者虽极早期或早期疠气挟夹寒湿为患，但速传于肺，以致出现高热、咳嗽、苔黄腻等肺热之征，秉承“祛邪为第一要义”，笔者临床根据王灿晖教授理论观点，施以“清热透邪”之法，获得良好效果，并列举典型案例，以期丰富中医药治疗新冠肺炎的理论与实践。     

Association between Serum Osteocalcin Levels and Metabolic Syndrome according to the Menopausal Status of Korean Women

BackgroundOsteocalcin is known to regulate energy metabolism. Recently, metabolic syndrome (MetS) has been found to be associated with reduced levels of osteocalcin in men, as well as in postmenopausal women. The aim of this study was to investigate the association between serum osteocalcin and MetS in premenopausal women, compared with that in postmenopausal women.MethodsThis cross-sectional study was based on 5,896 participants who completed a health screening examination. They were classified according to their menopausal status. Each group was subdivided into non-MetS and MetS groups according to the modified National Cholesterol Education Program-Adult Treatment Panel III criteria. Serum osteocalcin levels were measured using the electrochemiluminescence immunoassay.ResultsSerum osteocalcin level was significantly lower in women with MetS than in those without MetS, after adjusting for confounders (14.12 ± 0.04 vs. 13.17 ± 0.13 [P = 0.004] in premenopausal women, and 20.34 ± 0.09 vs. 19.62 ± 0.21 [P < 0.001] in postmenopausal women), regardless of their menopausal status. Serum osteocalcin levels decreased correspondingly with an increasing number of MetS elements (P for trend < 0.001). Multiple regression analysis demonstrated that waist circumference (β = −0.085 [P < 0.001] and β = −0.137 [P < 0.001]) and hemoglobin A1c (β = −0.09 [P < 0.001] and β = −0.145 [P < 0.001]) were independent predictors of osteocalcin in premenopausal and postmenopausal women. Triglyceride levels were also independently associated with osteocalcin levels in premenopausal women (β = −0.004 [P < 0.013]). The odds ratio (OR) for MetS was significantly higher in the lowest quartile than in the highest quartile of serum osteocalcin levels after adjusting for age, alkaline phosphatase, uric acid, high sensitivity C-reactive protein, and body mass index in all women (OR, 2.00; 95% confidence interval [CI], 1.49–2.68) as well as in premenopausal (OR, 2.23; 95% CI, 1.39–3.58) and postmenopausal (OR, 2.01; 95% CI, 1.26–3.23) subgroups.ConclusionLower serum osteocalcin concentrations were significantly associated with MetS in both premenopausal and postmenopausal women and were therefore independent of menopausal status.     

约束隐结构研究冠心病痰湿证的定量化辨证规则＊

目前在中医界已发布的冠心病痰湿证辨证标准是以主症、次症形式定性地给出，存在主观性较强的问题。本文引入约束隐结构分析，该方法将主症、次症的语义作为约束条件加入隐结构分析过程，得到含有主症、次症语义约束的定量化中医证候辨证规则。使用该方法对冠心病痰湿证患者556条无标签数据的分析，得到其约束隐结构模型，最后建立定量化痰湿证辨证规则，舌胖边有齿痕（3.16）、苔腻（3.12）、苔白滑（4.72）、胸闷（1.73）、脉濡或滑（6.04）；次症：肢体困重（0.48）、口黏（0.63）、体胖（0.49）、大便粘滞（1.38）、脘腹痞满（0.97）、面色晦浊（0.79）、嗜睡（1.18）、纳差（1.07）。与经典隐结构模型得到规则和中医界已发布的定性化辨证规则相比，约束隐结构得到的规则客观性强，具有可重复性。在证候类大小、规则的量化合理度上较好地反映了主症、次症的特点，得到的规则切合中医实际，为冠心病痰湿证辨证标准的定量化研究提供帮助和参考。

Oral and dental findings in emanuel syndrome

Emanuel Syndrome (ES; OMIM# 609029) is a rare disorder caused by an unbalanced chromosomal translocation [supernumerary der(22)t(11,22)] and characterized by multiple congenital abnormalities. With limited published cases and low prevalence (1:110 000), detailed ES‐associated oro‐dental findings have not previously been reported. This is a case report of a 14‐year‐old boy with ES who presented with congenital cardiac, renal, auditory, musculoskeletal problems, and global developmental delay. The patient was managed with risperidone, melatonin, omeprazole, guanfacine, and oxcarbazepine. Anxiety‐associated self‐injurious behaviour was seen along with stereotypic hand movements. Consistent with previous reports, microcephaly and micrognathia were noted. Oro‐facial cleft or gross asymmetry, however, was not observed. Significant oro‐dental findings included delayed eruption of primary and permanent teeth, oligodontia (two erupted and five unerupted permanent teeth), and short‐root anomaly of central incisors. The patient demonstrated anxiety‐triggered bruxism with generalized attrition. This case report provides a comprehensive list of systemic ES findings along with oro‐dental manifestations, which have previously not been reported in detail.
