IgA nephropathy is a complex disease with unclear mechanism,microRNAs may involve in the disease,and some of them may be associated with the key enzyme of IgA nephropathy-core β1 3-galactosyl-transferase.The concept of epigenetics and the structures and functions of microRNA were introduced.Through reviewing the related researches,several microRNAs expressing abnormally in IgA nephropathy was found.

OBJECTIVE:To study the direct powder compression technology of Angelica micropowder. METHODS: The formula of Angelica micropowder was optimized by mixture uniform design with tablet weight variation and friability as restrictive conditions, and a regression equation was established based on the comprehensive grading on the hardness and disintegration to figure out the optimal solution. DPS software was applied in the calculation. RESULTS: Prepared by the direct powder compression technology, the optimal formula of Angelica micropowder was obtained as follows: the hardness of the optimized tablet could reach as high as 75 N and the disintegrating time was about 10.24 min, with smooth and intact surface. CONCLUSION:The technology is reasonable in formulation and satisfactory in molding, and it can serve as theoretical basis for the production of Angelica tablets.

Psychometrical methodology was widely applied in the development of TCM syndrome scales,without considering the consistency between the methods and clinical TCM syndrome differentiation practice and the difference between the syndrome diagnosis and syndrome evaluationt.In this article,we described the theory foundation of the TCM syndrome diagnosis scales,distinguished the difference between the syndrome diagnosis scales and syndrome evaluation scales from several aspects,and expounded the key steps and technical point of TCM syndrome diagnosis scales development superfi cially.Ischemic Stroke TCM Syndrome Scales based on these represented a satisfying performance in clinical validation.

Objective To investigate the anti-oxidation effects of compound Chinese medicine of Yiqiling,on the spon- taneously hypertensive rats(SHR) and to explore the new target for improving the prognosis of hypertension.Method SHR were randomly divided into 2 groups:Yiqiling group and the control group.The serum content of malondiadehyde (MDA) and superoxide dismutase(SOD),and the urine content of 8-iso prostaglandin F2?(8-isoPGF2?) in two groups were measured.Examination of the gene expression profile was analyzed by using cDNA microarray.Three of the anti-oxidation genes were selected to undergo RT-PCR and quantitative real-time PCR.Results The 8-isoPGF2?urine level and MDA serum level were lower,and SOD serum level was higher in Yiqiling group than those in the control group,the differences of the above indexes had statistical significance.In Yiqiling group the expression of 354 genes was up-regulated and that of 121 genes was down-regulated in comparison with the control group.The results of the Hsphl,Hspca and Pam genes detected by RT-PCR and quantitative real-time PCR were consistent with those detected by the microarray examination.Conclusion Yiqiling has anti-oxidation effects and improvement on the prognosis of SHR,and its possible mechanism is related with the regulation of Hsphl,Hspca and Pam genes expression.

To discuss the distribution and evolvement of TCM syndromes in ischemic stoke,we investigated the TCM diagnostic data from 195 cases in the first three months.After the cluster analysis based on the data of the first 3 days,28 days,90 days after the attack,information of the first three days indicated that the variables could cluster into qi deficiency and blood stagnation,phlegmheat,qi and yin deficiency three groups;the information of the 28 days indicated that the variables could cluster into qi deficiency,phlegm-wet,blood stagnation,phlegm-heat four groups;the information of the 90 days indicated that the variables could cluster into qi deficiency and blood stagnation,qi deficiency,phlegm-heat and phlegm-wet four groups.The cluster analysis result shows us a dynamic process of the syndrome evolvement,TCM syndromes are variance in different stage,and become simplicity from complex after treatments.

The discovery of limbal stem cells is the key advancement in ophthalmology in the 20th century.Many clinical researches have proved that limbal stem cells transplantation is an effective method to treat severe ocular surface diseases.However, some important issues associated with the identification,isolation,standardized culture in vitro and differentiation after transplantation are still not clear and need to be paid more attention.Strengthening the underlaying research in this field will play important role in treating corneal blindness.

Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.
