Progress of clinical application of microperimetry in ocular fundus diseases / 中华眼底病杂志

Microperimetry is a procedure to assess retinal sensitivity while fundus is examined directly.It is a psychophysical method which is rapid,safe and non-invasive.It combines analysis of function and morphology and has an eye tracking system that can improve the fixation stability of patient with eccentric fixation and fixation instable.Microperimetry is supplement to visual function,perimetry,and other visual function parameters.As deepening of research,its clinical application value in ocular fundus diseases including age-related macular degeneration,diabetic retinopathy,retinitis pigmentosa,Stargardt's disease,macular hole,rhegmatogenous retinal detachment and central serous chorioretinopathy needs to be further explored.

Study on Serum Pharmacochemistry of Ke-Luo-Xin Capsule / 世界科学技术-中医药现代化

This article was aimed to study the main effective substances and characteristics of Ke-Luo-Xin (KLX) capsule. HPLC-DAD system was applied in the establishment of HPLC finger prints of serum of rats after taking KLX capsule. And then, serum samples taken KLX capsule, blank blood serum, and single crude drugs were com-pared. Constituents absorbed into the serum were determined by HPLC-DAD system. The results showed that meth-ods for serum HPLC fingerprinting had good precision, reproducibility and stability. A total of 13 constituents migrat-ing to the blood were detected, of which 9 were prototype constituents, 4 were metabolites. Prototype constituents in-cluded aloeemodin and chrysophanic acid. It was concluded that 13 constituents migrating to the blood may be the main effective substances of KLX capsule.

Gene technique and modern Chinese materia medica / 中草药

Chinese materia medica (CMM) has double complexity in bioactive ingredient and its mechanism. It is difficult to explain by the modern biomedicine theory So it seriously restricts the modernization of CMM The modern CMM should have the high quality standard to meet the needs of international standard It can be guaranteed by spreading the GAP for Chinese medicinal materials and GMP for standard production The mechanism depends on using the DNA microarray to set up “the gene expression difference chart”, to study on the combination of CMM and gene expression difference chart Meanwhile, we can establish a totally new method of screening modern CMM based on the gene expression difference chart, it can really make the modernization and internationalization of CMM
