ABSTRACT
Nonalcoholic fatty liver disease （NAFLD） is a metabolic stress-induced liver injury characterized by excessive lipid accumulation in hepatocytes， which is closely related to insulin resistance and genetic susceptibility. It falls into the category of "liver lump" in traditional Chinese medicine （TCM）. NAFLD affects about 25% of the population worldwide and has become a major burden of the world health care system. However， its exact pathogenesis remains unclear. Conducting the basic research on NAFLD is of great clinical significance and social value. As an important tool for NAFLD research， animal model plays a particularly important role in clarifying the pathophysiological mechanism of NAFLD. In recent years， the modeling methods for NAFLD in China and abroad have been constantly updated， and in particular， certain progress has been made in the duplication of TCM syndrome models. By consulting and sorting out the relevant literature published in recent years in China and abroad， the author summarized the replication methods of NAFLD animal models. This paper reviewed the advantages and disadvantages of models established via dietary induction （high-fat feed， high-fat and high-fructose feed， high-fat and high-cholesterol feed， and methionine choline-deficient feed）， models with genetic defects ［leptin-deficiency （Lepob/Lepob）， autosomal recessive diabetes gene homozygous deficiency （ob/ob）， Alms1 gene （foz/foz） mutation， and FATZO mice］ and exposure to special diets， and models for TCM syndromes （liver depression and spleen deficiency syndrome， phlegm-dampness syndrome， blood stasis syndrome， combined phlegm and stasis syndrome， and qi stagnation and blood stasis syndrome）， in order to provide reference for the preparation of more scientific， reasonable， economical， and convenient animal models of NAFLD， thus laying a foundation for in-depth study of the pathogenesis， prevention， and treatment of NAFLD.
ABSTRACT
Objective:To investigate the distribution of traditional Chinese medicine (TCM) syndromes in patients with coronary heart disease (CHD) in 6 months after interventional therapy, and to analyze relevant influencing factors. Method:The clinical data of 1 000 patients with coronary heart disease in 6 months after interventional therapy, including the four diagnosis information of TCM, were collected, and the distribution of TCM syndromes and the influencing factors were analyzed. Result:Among 48 kinds of information about the four diagnostic methods of TCM, chest pain was the most frequent (98.10%)， among 9 kinds of common TCM syndrome types, blood stasis was the most frequent (89.90%), and the others were heart-Qi deficiency syndrome, phlegm turbidity syndrome, cold-dampness syndrome, kidney-Qi deficiency syndrome, heart-Yin deficiency syndrome, kidney-Yin deficiency syndrome, Heart-Yang deficiency syndrome and kidney-Yang deficiency syndrome in turn. Among 6 common TCM syndrome types, Qi deficiency and blood stasis syndrome were the most frequent (35.40%), and the others were phlegm turbidity and blood stasis syndrome, cold congealing heart pulse syndrome, Qi-Yin deficiency syndrome, heart-kidney Yin deficiency syndrome and heart-kidney-Yang deficiency syndrome in turn. There was no significant difference in sex ratio among different syndrome types . Patients with heart-kidney Yang deficiency syndrome had no significant difference. Compared with the average age of other syndromes, there were significant differences. Common complications included hypertension, diabetes, cerebrovascular diseases and dyslipidemia, among which hypertension had the highest frequency, with significant differences from other diseases (P<0.05). Phlegm, turbidity and blood stasis were found in patients with hypertension. The risk of syndromes was higher (OR=3.29, 95% CI [2.11, 5.05]), while the risk of cold congealing heart pulse syndrome was lower (OR=0.56, 95% CI [0.32, 0.98]), the risk of Qi and Yin deficiency was higher (OR=2.88, 95% CI [2.01, 4.99]), whereas the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95]) when complicated with cerebrovascular diseases. The risk of Qi deficiency and blood stasis was higher (OR=2.97, 95% CI [2.05, 5.28]), while the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95])， the risk of phlegm turbidity and blood stasis was higher when complicated with dyslipidemia (OR=3.55, 95% CI [2.32, 5.29]), and the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95]). The time distribution of the disease had obvious seasonal characteristics. Conclusion:The main distribution characteristics of TCM syndromes in 6 months after coronary heart disease intervention are basically the same as those in patients without intervention. The main TCM syndromes are Qi deficiency and blood stasis syndrome, phlegm turbidity and blood stasis syndrome, cold congealing heart pulse syndrome, Qi-Yin deficiency syndrome, heart-kidney Yin deficiency syndrome and heart-kidney-Yang deficiency syndrome. The distribution pattern may be related to age, complications and seasons.
ABSTRACT
Objective::To explore the distribution characteristics of traditional Chinese medicine (TCM) syndromes of critical lesions of coronary heart disease, and determine the classification and diagnostic criteria of syndromes, so as to provide reference for the differentiation and treatment of this disease. Method::Totally 1 000 patients with critical lesions of coronary heart disease treated in the Department of Cardiology, Yunnan Provinceal Hospital of TCM from January 2016 to December 2018 were selected as the subjects by clinical epidemiological research methods. Basic information, diagnosis and treatment of the patients, as well as the information obtained through observation, hearing, inquiry and pulse-taking of TCM were collected. Symptoms, signs, tongue signs, pulse signs and other four diagnostic information, as well as relevant clinical data were collected for mathematical statistics analysis by cluster analysis and factor analysis research methods, and expert group opinions were also included in discussion. Result::First, the results of cluster analysis showed six types of basic TCM syndromes in accordance with the clinically actual critical lesions of coronary heart disease: blood stasis syndrome, phlegm turbidity syndrome, cold congealing heart pulse syndrome, Qi deficiency syndrome, heart-kidney Yin deficiency syndrome, Heart-Yang deficiency syndrome. Second, a factor analysis was carried out on the basis of cluster analysis, and the main syndromes of each basic syndromes were preliminarily determined. Third, because of the duplicate content or the unified combination of different syndromes, the TCM syndromes of the critical lesions of coronary heart disease can be summarized in five categories, namely phlegm turbidity and blood stasis syndrome (368 cases, 36.80%), cold congestion heart pulse syndrome (156 cases, 15.60%), Qi deficiency and blood stasis syndrome (315 cases, 31.50%), Yin deficiency of heart and kidney (91 cases, 9.10%) and Heart-Yang depression (70 cases, 7.00%). The main and secondary syndromes refer to factor analysis results of six basic syndromes. Conclusion::Cluster analysis and factor analysis can be made on TCM syndromes of critical lesions of coronary heart disease to pave the way for the classification of TCM syndromes and the establishment of diagnostic criteria of TCM syndromes of coronary heart disease, with an important clinical significance.
ABSTRACT
Objective To analyze the distribution of traditional Chinese medicine(TCM)syndromes in patients with acute pulmonary embolism(APE)and to summarize the medication rule,so as to supply evidence for the clinical diagnosis and treatment of APE. Methods A retrospective study was carried out in the APE inpatients admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine in recent 4 years. The general data, clinical manifestations at the attack of APE, TCM syndromes, treatment and prognosis of the included patients were input into the database for the analysis of TCM syndrome distribution and medication rule. Results A total of 139 cases of APE patients were included into the study. The main manifestations at admission were dominated by dyspnea and chest pain, pale or darkish red tongue, string pulse and deep pulse. TCM syndromes were divided into three types, phlegm turbidity syndrome, blood stasis syndrome and yang collapse syndrome. The blood stasis syndrome accounted for the largest proportion and then came the phlegm turbidity syndrome. In various age groups,the 3 syndrome types accounted the highest proportion in the age group of 51-70 years old, and accounted higher proportion in the age group over 71 years old. Blood stasis syndrome was frequently seen in the age group below 30 years old. Xuefu Zhuyu Decoction and Tao Hong Siwu Decoction were frequently used for the treatment of blood stasis syndrome, Gualou Xiebai Banxia Decoction and Wendan Decoction were often used for the phlegm turbidity syndrome, and Shenfu Injection was often used for yang collapse syndrome. Conclusion APE occurs in various clinical departments, and phlegm turbidity syndrome, blood stasis syndrome and yang collapse syndrome are the main syndrome patterns of APE. Blood stasis syndrome accounts the largest proportion in clinic. Therefore, Xuefu Zhuyu Decoction and Tao Hong Siwu Decoction, Gualou Xiebai Banxia Decoction and Wendan Decoction should be used as the indicated recipes for APE to activate blood and remove stasis, strengthen spleen and resolve phlegm.
