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。     

中医药调控益生菌防治肺炎的研究进展＊

肺炎是呼吸系统疾病中的常见疾病，发病率高，可伴有多种并发症，严重时可危及生命健康。肺炎患者多伴有肠道菌群失调，表现为有益菌减少，且益生菌可通过“肠-肺轴”影响肺部免疫参与肺炎的发生发展。中医以“肺”与“大肠”两者之间的生理及病理关系为基础，通过整体观念和辨证论治发挥了治疗肺炎的独特的优势。近年来，许多研究表明中医药在治疗肺炎的过程中具有改善肠道微生态作用，但肺炎的中医辨证分型与肠道菌群的相关性尚不明确。本文从中医辨证分型论治肺炎的角度出发，总结不同辨证分型的肺炎与肠道菌群结构特征，阐述中医治疗肺炎过程中对于益生菌的调节作用和“证型—中药—益生菌”的对应关系。通过讨论益生菌在防治肺炎中的关键作用，展望中医辩证联合益生菌治疗肺炎的应用前景，以期为肺炎的防治提供新思路和新靶点，也为将来指导不同肺炎证型患者选择适合的中药及益生菌提供理论依据。

Adjuvant chemotherapy could improve the survival of pulmonary sarcomatoid carcinoma: A systematic review and meta-analysis

BackgroundComplete surgical removal is currently considered to be the best treatment option for pulmonary sarcomatoid carcinoma (PSC) especially in early stage operable disease; however, the reported recurrence-free survival is low. Benefits of adjuvant chemotherapy in PSC patients are still controversial, and there is no obvious agreement on the optimal treatment modalities of this disease. Therefore, we aimed to investigate the prognosis in terms of overall survival (OS) in patients with PSC who received adjuvant chemotherapy.MethodsThe review protocol was registered in PROSPERO (CRD42022306084). Patients with PSC who underwent surgical therapy with or without adjuvant chemotherapy were included into the meta-analysis. Hazard ratios (HR) with 95% confidence intervals (CIs) for OS were pooled and ROBINS-I tool was used to assess risk of bias of the included studies.ResultsWe identified four retrospective cohort studies with 6768 records from MEDLINE, Embase, and CENTRAL databases up to 9th September 2021, and altogether 1835 patients were included to the analysis. The present meta-analysis shows that patients receiving adjuvant chemotherapy had a significantly longer OS than patients who underwent surgical treatment alone (HR = 0.5657, 95%CI: 0.4391–0.7290, p < 0.0001).ConclusionsDespite the limited information on the chemotherapy regimens in the included studies, patients with PSC may benefit from adjuvant chemotherapy. More publications are required to evaluate and compare efficient adjuvant chemotherapy protocols in PSC cases.

辨体-辨病-辨证诊疗模式在慢性病防治中的应用策略

依据中国防治慢性病中长期规划（2017-2025年），按照国医大师王琦教授倡导的"辨体-辨病-辨证诊疗模式"，提出慢性病"3+4+3"防治路向：面向三类人群（一般、高危、患病人群），朝向四种状态（无病、病前、病中、病后状态），指向三辨模式（辨体-辨病-辨证诊疗模式）。进而探讨其应用策略：对于一般人群无病状态——辨体养生，固本防病；对于高危人群病前状态——辨体干预，治本救萌；针对患病人群病中状态——"三辨"施治，标本兼顾；针对患病人群病后状态——辨体调理，固本防复。文中结合案例加以佐证，具有临床指导价值。
