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

<p><b>OBJECTIVE</b>To confirm that PCR products with heterozygous mutations contain not only wide-type and mutant homoduplexes, but also two types of heteroduplexes.</p><p><b>METHODS</b>An insertion-deletion mutation in the exon 1 of KRT9 gene (497delAinsGGCT), which caused Chinese epidermolytic palmoplantar keratoderma (EPPK) was investigated by polymerase chain reaction (PCR), polyacrylamide gel electrophoresis (PAGE) and denaturing high-performance liquid chromatography(DHPLC).</p><p><b>RESULTS</b>Two heteroduplexes and two homoduplexes in the PCR product from the heterozygous mutation of the exon 1 of KRT9 (497delAinsGGCT) were detected.</p><p><b>CONCLUSION</b>PCR products from KRT9 gene with heterozygous mutations contain two types of heteroduplexes. It is without the need to perform heating and cooling PCR products obtained from heterozygous mutations in advance before the mutation screening steps such as denaturing gradient gel electrophoresis (DGGE), temperature gradient gel electrophoresis (TGGE), conformation-sensitive gel electrophoresis (CSGE), DHPLC and heteroduplex analysis (HA), etc.</p>

ABSTRACT

In this article we reviewed the current researches on the molecular basis of epidermolytic palmoplantar keratoderma (EPPK) and the structure and function of the keratins with mutations that can cause inherited keratin disorders. Also summarized are seventeen mutations of keratin 9 in EPPK in different ethnic populations.
