Methods： One hundred and fifteen patients of CG-PDS who suffered from intestinal metaplasia （IM） and atypical hyperplasia （ATHP） of gastric mucosa, were divided into two groups. The treated group （n=61） was treated by WKFG with its ingredients modified according to the syndrome type of patients. The control group（n=54） was treated with Weishu granule （胃舒冲剂）. The histopathological and subcellular ultrastructural changes were detected by optical microscope, screening electronic microscope, transmission electronic microscope and histochemical staining; the nuclear and mitochondrial ultrastructure of gastric mucosa were analyzed with energy dispersion X-ray analyser and image analysis system. And the changes of cAMP, lipid peroxide （LPO）, superoxide dismutase （SOD） before and after treatment in the treated group were measured and compared with those of the health control group consisting of 15 volunteers. Results： The symptomatic and pathological therapeutic effect in the treated group were significantly superior to those in the control group （P〈0.05）. The contents of Zn, Cu, cAMP, SOD and 3H-TdR LCT in gastric mucosa of the treated group before treatment were all lower than those of the healthy control group, yet all these indexes markedly increased after treatment, while serum LPO level, which increased before treatment was lowered after treatment. All the changes showed statistical significance （P〈0.05 or P〈0.01）. Conclusion： WKFG can reverse IM and ATHP in patients of CG-PDS, and the effect may be realized by way of increasing the level of Zn, Cu, cAMP and SOD in gastric mucosa, promoting cell differentiation, enhancing cellular immunity and reducing oxygen free radicals and lipid peroxidation.展开更多

PS are neurodegenerative diseases which are clinically characterized by a hypokinetic phenotype in combination with additional motor and non-motor symptoms. One major pathological hallmark of all PS consists of a non-physiological detrimental accumulation of protein aggregates which appear intracellularly in neurons and glial cells but also in the extracellular space (Wong and Krainc, 2017). Depending on the pathogenic protein, PS can be divided into synucleinopathies, characterized by aggregation of the protein alpha-Synuclein (aSyn), and tauopathies, characterized by aggregation of the protein Tau (Levin et al., 2016;Poewe et al., 2017). Clinical syndromes of synucleinopathies include Parkinson’s disease (PD), multiple system atrophy (MSA) and dementia with Lewy bodies, and tauopathies include progressive supranuclear palsy (PSP) and corticobasal degeneration.展开更多

Methods： With the BRB-Array Tools software package, original data collection and bioinformatic analysis of gene arrays were conducted in 6 CSG patients of PDS （CSG-PDS）, 6 CSG patients of non-PDS （CSG-nPDS）, and 6 healthy volunteers （Normal）. Results： Compared with non-PDS, the gene expressions in PDS with regards to protein synthesis, energy metabolism, immune reaction and ionic transport tended to be down-regulated, while those concerning secretion, cytoskeleton and ubiquitinization were up-regulated dominantly. Conclusions： The two kinds of samples, CSG-PDS/Normal and CSG-PDS/CSG-nPDS, have their respective gene expression profiles with different characteristics. Gene expression profile has certain referential significance in syndrome classification.展开更多

Methods： Sixty-eight patients with confirmed coronary heart disease （CHD） were selected for TCM syndrome typing into Pi- deficiency （PD） group and non-Pi-deficiency （NPD） group. Routine blood lipids and serum lipoprotein electrophoretogram （SLPG） were determined in all patients to analyze the total content of HDL and its relative contents of sub-components HDL1-5, as well as their relation with PD syndrome. Besides, a healthy control group （62 cases） was set up. Results： The level of serum HDL-C was lowered, SLPG abnormality rate increased in the patients with CHD, with total HDL and the relative contents of sub- component HDL1 and HDL3 significantly lower than those in the healthy control group （P〈0.01）. The total HDL, HDL1 and HDL3 in the PD group were also lower than those in the NPD group （P〈0.05, P〈0.01）. Conclusion： Serum HDL and its sub-components showed a definite relation with TCM PD syndrome type, therefore, further exploring the granular specificity of HDL and its sub-components as well as their influence on reverse cholesterol transport （RCT） may hopefully provide clues for developing RCT regulatory Chinese new drugs and for CHD prevention and treatment.展开更多
