Establishment and evaluation of a mouse model of bronchial asthma with Yin deficiency syndrome

Objective: To establish and evaluate a mouse model of bronchial asthma with Yin deficiency syndrome. Methods: The mouse model of bronchial asthma with Yin deficiency syndrome was established by the treatment with injecting ovalbumin(OVA) two times to sensitize, inhaling OVA 14 times to stimulate, and using thyroxin through lavage during late stimulation. This model was evaluated through body weight, asthmatic behaviors, respiratory function, autonomous activity, lung pathology, and pulmonary fluid clearance. Results: OVA combined with thyroxin was an appropriate method to induce the mouse model with increased food and water intake, autonomous activity, asthmatic behaviors score, and respiratory rate, decreased body weight, tidal volume, and wet/dry ratio of lung, and changed with pathology of lung tissue. The changes of the above mentioned parameters indicated that the model was the bronchial asthma with Yin deficiency syndrome. Conclusion: The OVA combined with thyroxin is a good pattern to establish a mouse model of bronchial asthma with Yin deficiency syndrome successfully, which can highly simulate the clinical symptoms of this disease.

Study on syndrome differentiation based on pharmacology of syndrome management system-a case of Qi and Yin deficiency syndrome

Taking the Qi and Yin deficiency syndrome as an example,the research method of pharmacology of syndrome management system was proposed.By means of text mining,systematic pharmacology and target analysis,to attempt to reveal the essence of the corresponding syndrome by studying the drugs and targets of Qi and Yin deficiency.Fourteen Chinese herbs treating Qi and Yin deficiency were retrieved and used more than 30 times,and 9,317 related targets were predicted.The common targets of action were 85.Topological analysis was carried out by using degree centrality,closeness centrality and betweenness centrality to confirm that estrogen receptor(ESR1),tumor necrosis factor(TNF),D(2)dopamine receptor(DRD2),vitamin D3 receptor(VDR),glucocorticoid receptor(NR3C1),acetylcholinesterase(ACHE)and endothelin-1(EDN1)were highly correlated with Qi and Yin deficiency syndrome.Through the target to find Qi and Yin deficiency syndrome corresponding to 17 categories of diseases.A new idea was provided for studying the biological essence of TCM clinical syndrome differentiation.

Study on blood pressure rhythm in hypertensive patients with Yin deficiency syndrome and a random forest model for predicting hypertension with Yin deficiency syndrome

OBJECTIVE: To investigate blood pressure rhythm(BPR)in Yin deficiency syndrome of hypertension(YDSH)patients and develop a random forest model for predicting YDSH.METHODS: Our study was consistent with technical processes and specification for developing guidelines of Evidence-based Chinese medicine clinical practice(T/CACM 1032-2017). We enrolled 234 patients who had been diagnosed with primary hypertension without antihypertensive medications prior to the enrollment. All participants were divided into Yin deficiency group(YX, n = 74) and non-Yin deficiency group(NYX, n = 160).Participants were professionally grouped by three experienced chief Traditional Chinese Medicine(TCM)physicians according to four examinations(i.e.,inspection, listening and smelling, inquiry and palpation).We collected data on 24 h ambulatory blood pressure monitoring(ABPM) and YDSH rating scale. We divided 24 h of a day into 12 two-hour periods [Chen-Shi(7:00-9:00), Si-Shi(9:00-11:00), Wu-Shi(11:00-13:00), Wei-Shi(13:00-15:00), Shen-Shi(15:00-17:00), You-Shi(17:00-19:00), Xu-Shi(19:00-21:00), Hai-Shi(21:00-23:00), ZiShi(23:00-1:00), Chou-Shi(1:00-3:00), Yin-Shi(3:00-5:00), Mao-Shi(5:00-7:00)] according to the theory of “midnight-midday ebb flow”. We used random forest to build the diagnostic model of YDSH, with whether it was Yin deficiency syndrome as the outcome. RESULTS: Compared with NYX group, YX group had more female participants with older age, lower waist circumference, body mass index(BMI), diastolic blood pressure(DBP), and smoking and drinking rate(all P < 0.05). The YDSH rating scores of YX group [28.5(21.0-36.0)] were significantly higher than NYX group [13.0(8.0-22.0)](P < 0.001), and the typical symptoms of YX group included vexing heat in the chest, palms and soles, dizziness, dry eyes, string-like and fine pulse, soreness and weakness of lumbus and knees, palpitations, reddened cheeks, and tinnitus(all P < 0.05). The ratio of non-dipper hypertension in YX group was higher than in NYX group(56.9% vs 44.4%, P = 0.004). Compared with NYX group, 24 h DBP standard deviation(SD), nighttime DBP SD, Si-Shi DBP, Si-Shi mean arterial pressure(MAP), Hi-Shi systolic blood pressure(SBP), Hi-Shi DBP, Hi-Shi MAP, Zi-Shi SBP, Zi-Shi DBP, Zi-Shi MAP, ChouShi SBP SD, Chou-Shi DBP SD, Chou-Shi SBP coefficient of variation(CV) were lower in YX group(all P < 0.05). Binary Logistic Regression analysis showed that the diagnosis of YDSH was positively correlated with age, heart rate, YDSH rating scores, and four TCM symptoms including vexing heat in the chest, palms and soles, string-like and fine pulse, soreness and weakness of lumbus and knees, and reddened cheeks(all P < 0.05), but was negatively correlated with smoking(P﹥0.05). In addition, the diagnosis of YDSH was positively correlated with daytime SBP SD, nighttime SBP SD, nighttime SBP CV, and Hi-Shi SBP CV, but was negatively correlated with 24 h SBP CV, daytime DBP SD, nighttime DBP SD, and Hi-Shi DBP(all P < 0.05). Hi-Shi SBP CV had independent and positive correlation with the diagnosis of YDSH after adjusting the variables of age, gender, course of hypertension, BMI, waist circumference, SBP, DBP, heart rate, smoking and drinking(P = 0.029). Diagnostic model of YDSH was established and verified based on the random forest. The results showed that the calculation accuracy, specificity and sensitivity were 77.3%, 77.8% and 76.9%, respectively. CONCLUSION: The BPR was significantly attenuated in YDSH patients, including lower 24 h DBP SD and nighttime DBP SD, and Hi-Shi SBP CV is independently correlated with the diagnosis of YDSH. The prediction accuracy of diagnosis model of YDSH based on the random forest was good, which could be valuable for clinicians to differentiate YDSH and non-Yin deficiency patients for more effective hypertensive treatment of TCM.

Summary and correlation analysis of TCM syndromes in 159 elderly patients with acute myeloid leukemia

Objective:To investigate the characteristics of TCM syndromes in elderly patients with acute myeloid leukemia(AML)at the onset,and to analyze the main syndrome types and their correlation with age,percentage of bone marrow blasts,and genetic prognostic stratification.Methods:A retrospective analysis was performed on 159 AML patients aged over 60 years who were diagnosed and treated in our hospital,and the clinical data were collected and analyzed statistically.Results:In 159 elderly AML patients,the main clinical symptoms were fatigue,poor appetite,conscious fever,and various hemorrhages.The main syndromes were Ying(42.01%),Wei(31.25%),Essential(14.81%)and Blood(11.69%);the syndromes are divided into Qi and Yin deficiency(32.70%),Qi and blood deficiency(30.19%),true Yin deficiency(28.03%)and Qi heat and blood(8.81%).The age difference between the two groups was statistically significant(P<0.001),and the multiple comparison results showed that the age of the Qi-blood deficiency group was younger than the true-Yin deficiency group and the Qi-Yin deficiency group;the percentage of bone marrow blasts was statistically significant in the three groups at the initial diagnosis(P<0.05),multiple comparison results showed that the percentage of bone marrow blasts in the true Yin deficiency group was higher than that in the Qi-blood deficiency group and the Qi-Yin deficiency group;the genetic prognostic stratification of the three groups was statistically significant(P<0.05),multiple comparisons.The results showed that the genetic prognosis of the true Yin deficiency group was poorer than that of the Qi and blood deficiency group and the Qi and Yin deficiency group.Conclusion:The most common clinical symptoms of elderly AML patients are fatigue,the disease is located in the bone marrow,and the disease is Ying,Wei,essence,and blood.With the increase in the patient's age,the TCM syndrome types tend to be more insufficiency of true Yin and deficiency of both Qi and Yin,and the prognosis of patients with insufficiency of true Yin is poor.It provides a directional scientific basis for the treatment of senile AML with integrated traditional Chinese and Western medicine.

刘树民教授治疗气阴两虚型甲状腺功能亢进症临床经验

甲状腺功能亢进症(简称甲亢)是一种临床常见病、多发病。现代医学治疗甲亢的方案主要是口服甲巯咪唑片、放射性碘治疗和手术治疗,上述3种方法不良反应较多,后期容易出现甲状腺功能减退。刘树民教授从事内科杂病治疗30余年,擅长运用中医辨证思维治疗各种疑难杂症。他认为,甲亢的病因隐匿且复杂,其基本病机为本虚标实。本虚以气阴两虚为主;标实以肝郁气滞较为常见。研究从病因病机、临床特征、治疗等方面系统分析、总结了刘树民教授运用芪玄抑甲宁为基础方治疗甲亢气阴两虚证的临证经验。建议在辨证治疗时注意以下5个要点:第一,注重疏理肝之郁气。肝气郁结是标实的主要外在表现,理气调肝为其治疗大法。第二,注重肝与心对调节情志的协同之功。肝藏血与心主血、肝藏魂与心藏神乃调节情绪、情志,维持精神、思维愉悦的关键,临证时应肝、心同调,以求情志畅达。第三,注重肝与肾的子母生化关系。肾、肝为母子之脏,肾水涵木,肾阴可滋生肝阴,以制约肝阳。第四,注重肝与脾的关系。肝和脾属五行相克,但相克太过即出现肝木乘脾土的情况,应注重肝脾之生克以求木土之平衡。第五,注意饮食。避免进食辛辣之品以防耗伤阴津及削弱中药滋阴之效。

中西医诊治儿童性早熟研究进展

目前,越来越多的无创诊断技术正在运用到儿童性早熟的诊断中,基因检测技术促进了该病遗传病因诊断的发展。对于该病的治疗,西医主要通过病因治疗继发性性早熟,对于特发性外周性性早熟没有特殊治疗方案,目前,中枢性性早熟治疗首选促性腺激素释放激素类似物(gonadotropin-releasing hormone agonist, GnRHa)。中医认为,性早熟病机为阴虚火旺,肝郁化火,痰湿壅滞,治以滋阴降火、疏肝解郁或燥湿化痰,可改善症状,抑制骨龄快速增长。但目前中医药治疗性早熟的临床研究证据等级不高,缺少样本量大、严格且全面的临床研究,未来可通过开展多中心的随机对照、大样本研究以验证中医药治疗性早熟的疗效。网络药理学和中药成分动物实验研究证明了中药治疗性早熟的部分机制,但中药方剂成分复杂,多通过胃肠道吸收后起效,是否可以调节肠道菌群、产生特异性菌群,该菌群是否改变了机体中某些代谢产物水平从而发挥治疗作用尚无相关研究,今后可开展更多的相关机制研究。

“瘦人多火症”的因机证治探析

提出消瘦是临床常见的体质状态,常常会伴随“瘦人多火症”相关证候表现。阴气不足是形体消瘦的主要生理、病理基础,燥火偏旺是形体消瘦的继发表现,病位涉及五脏,核心在脾。治疗原则以滋养阴气为主,宣发郁热为辅。具体包括治本与治标两个方面,治本当滋养阴气以改善“消瘦”体质,治标在发散郁热以消除“多火”状态,二者孰轻孰重应依据火旺轻重缓急而定。临床根据病情之标本缓急、消瘦而能食不能食、火热之虚实微盛、病机兼夹以及季节等因素进行药味加减。

从“内伤脾胃,百病由生”探析糖尿病泌汗异常

《脾胃论》提出了“内伤脾胃,百病由生”的认识,以此为理论基础探讨糖尿病泌汗异常病机演变及辨证治疗。认为本病的发展为饮食劳役,先伤脾胃,导致元气亏损,阴火上行,进而营卫失和,阳损及阴,致汗出异常。治疗上应当注重糖尿病的治疗,兼顾汗证。食疗为先,重用甘味,补阳泻火,平衡气火。明确糖尿病泌汗异常与中焦脾胃功能的密切关系,以期提高临床辨证论治疗效。

阴虚水肿浅见

水肿病与肺的通调、脾的转输、肾的水液代谢调节、肝的疏泄、心的行血、三焦的气化有关。多数医家认为水为阴邪,得温则化,故虚证水肿多与脾肾阳气虚损有关,治疗常应用具有温热作用的中药以化水。但阴虚水肿亦不少见。阳虚、阴虚均可导致水肿的发生,现代医家多重视阳虚水肿,对阴虚水肿有所忽视。故此文对阴虚水肿的病因及治疗方剂(济阴汤、白茅根汤、加减八味地黄汤、滋阴清燥汤、猪苓汤)进行论述,尤推《医学衷中参西录》之济阴汤、白茅根汤、加减八味地黄汤。
