ABSTRACT
Psoriasis (Ps) is an inflammatory skin disease caused by genetic and environmental factors. Previous studies on DNA methylation (DNAm) found genetic markers that are closely associated with Ps, and evidence has shown that DNAm mediates genetic risk in Ps. In this study, Consensus Clustering was used to analyze DNAm data, and 114 Ps patients were divided into three subclassifications. Investigation of the clinical characteristics and copy number variations (CNVs) of DEFB4, IL22, and LCE3C in the three subclassifications revealed no significant differences in gender ratio and in Ps area and severity index (PASI) score. The proportion of late-onset ( ≥ 40 years) Ps patients was significantly higher in type I than in types II and III (P = 0.035). Type III contained the smallest proportion of smokers and the largest proportion of non-smoking Ps patients (P = 0.086). The CNVs of DEFB4 and LCE3C showed no significant differences but the CNV of IL22 significantly differed among the three subclassifications (P = 0.044). This study is the first to profile Ps subclassifications based on DNAm data in the Chinese Han population. These results are useful in the treatment and management of Ps from the molecular and genetic perspectives.

A series of noscapine analogues have been synthesized via 13-step reaction starting from 2-hydroxy-3-methoxybenzaldehyde. Anti-tumor activities of these compounds were evaluated against HL-60 cell lines in vitro by the standard MTT assay. It was found that most of these derivatives showed appreciable inhibitory activity against HL-60 and tubulin polymerization. The results also indicated that the potency of compound 31 is about three times more than that ofnoscapine against HL-60 cell line and tubulin polymerization. Moreover, it induced a massive accumulation of cells in G2/M phase. These results showed noscapine and its derivatives were worth to be intensively studied further.
ABSTRACT
TCM is an opening science. With endless absorption of the contemporaneous achievement,organic combination of contemporaneous new theories,and under the guidance of the own philosophical methodology,the TCM achieves innovation and development. However,under the background of modern technology,the theory of TCM has not been innovated far insufficiently,which effects the development of TCM to a great extent.
ABSTRACT
One of the characteristics and advantages of Chinese medicine is holism,which emphasizes harmony of human and nature.It compares the physiological and pathological change of human body with the natural normal or unmoral change by using thinking of analogy by classification,inferring the internal essence according to external synptoms and signs.And it intends to reveal body black-box,and holds physiological and pathological change from macroscopic level,but there are some fuzziness and ambiguity.With the development of morden science on the microscopic fields,some breakthroughs and theoretical systems are established.As the same,Chinese medicine holism must be micro-adjusted and establish its own micro-holism theory,which will be benefit for itself.
ABSTRACT
Achievements of the 30-year research work on Pi-Wei Doctrine were summarized. They are: (1) ratio of salivin activity and excretion rate of D-xylose in patients with spleen deficiency are different from those in the normal subjects;(2) the principle of syndrome differentiation and treatment is embodied in the methodology of herbal medicine pharmacology for complex prescription; (3) the above findings are further confirmed by the research in molecular and cellular level which indicates that TCM syndromes and pharmacological mechanisms of herbal medicines have their material basis and the regulatory effect of complex prescription on TCM syndromes is actually the pharmacological mechanism of herbal medicines. It is suggested that the research of herbal medicine should be based on the guidance of traditional Chinese medicinal theory and carried out in clinical practice.
ABSTRACT
[Objective] To investigate the pathological features, secretion of interleukin-8 (IL - 8), tumor necrosis factor alpha (TNF-?) and secretory immunoglobulin A (sIgA) and helicobacter pylori (HP) infection in gastric mucosa (GM) of chronic superficial gastritis with spleen-stomach and damp-heat syndrome (SSDHS) and to explore their correlations. [Methods] Fifty-five cases of chronic superficial gastritis included 35 cases of SSDHS (Group A) and 20 cases of spleen-deficiency syndrome (Group B). Fifteen asymptomatic volunteers served as normal control group (Group C). Pathological changes, HP infection rate, levels of IL - 8, TNF -? and sIgA in GM were observed. [Results] HP infection rate was higher and inflammatory change was more obvious in Group A than those in Group B and Group C (P 0.05). [Conclusion] Gastric mucosa of chronic superficial gastritis with SSDHS presents inflammatory changes, which is related with the increase of IL - 8 and TNF -? secretion and the decrease of sIgA, and HP infection may be one of the factors inducing and enhancing the pathological changes.
ABSTRACT
Quality of ulcer healing (QUH) was applied to explore the mechanism of the recurrence of peptic ulcer. The relationship of QUH and epidermal growth factor, prostaglandins, heat shock proteins, immune function and Helico-bacter pylori was assayed. Mechanism of Chinese herbal medicine for the recurrence of peptic ulcer was presented as follows: improving blood circulation and barrier function of gastric mucosa, eliminating Helicobacter pylori and increas ing QUH.
ABSTRACT
Objective To establish a quality standard for Kangtai Capsule. Methods Kangtai Capsule was identified by TLC; the effective components in Kangtai Capsule were determined by HPLC. Results The relevant spots in Radix Paeoniae Alba, Radix Saposhnikoviae and Radix Aucklandlae were identified by TLC. the content of Paeoniflorin showed a good linearity in the range of 0.204～ 2.040 ? g, the average recovery rate was 97.9 % and RSD was 0.88 % . Conclusion This method is simple, feasible and repeatable, and can be used for quality control of Kangtai Capsule.
ABSTRACT
[Objective] To study the relationship between syndrome patterns of traditional Chinese medicine and bcl- 2 oncogene, p53 suppression gene mRNA expressions in precancerous lesions of gastric cancer (PIGC). [Methods] Forty PLGC cases were endoscopically and pathologically confinned, including 24 cases of moderate dysplasia of gastric mucosa, 9 cases of severe dysplasia, 7 cases of incomplete colonic intestinal metaplasia. Of the 40 cases, 10 were complicated with Qi stagnation, 12 with stomach-heat, and 18 with blood stasis, mRNA expression of bcl- 2 oncogene and p53 suppression gene were detected in situ by molecular hybridization method. [Results] The mRNA overexpression of bcl- 2 oncogene and p53 suppression gene were found in PLGC, and the expression was gradually increased with the progress of lesions. In the complicated cases, the mRNA expression of bcl- 2 oncogene and p53 suppression gene were the least in the cases with Qi stagnation and less in the cases with stomach- heat than in the cases with blood stasis. [Conclusion] Abnormal mRNA expression of bcl- 2 oncogene and p53 suppression gene were found in PLGC cases and related with different complicated cases, indicating the specificity of different syndrome patterns.
