The study of quality control of Chinese medicine has always been the hot and the difficulty spot of the development of traditional Chinese medicine (TCM), which is also one of the key problems restricting the modernization and internationalization of Chinese medicine. Multivariate statistical analysis is an analytical method which is suitable for the analysis of characteristics of TCM. It has been used widely in the study of quality control of TCM. Multivariate Statistical analysis was used for multivariate indicators and variables that appeared in the study of quality control and had certain correlation between each other, to find out the hidden law or the relationship between the data can be found,.which could apply to serve the decision-making and realize the effective quality evaluation of TCM. In this paper, the application of multivariate statistical analysis in the quality control of Chinese medicine was summarized, which could provided the basis for its further study.

?AIM:To investigate the measurement of central anterior chamber depth ( ACD ) in patients with acute primary angle - closure glaucoma ( APACG ) with A - scan ultrasound, Pentacam and ultrasonic biological microscope ( UBM) .?METHODS: Thirty-five patients (35 eyes) with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.?RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1. 5633±0. 2089, 1. 5783 ± 0. 2067, 1. 6275 ± 0. 2296mm, which was equal variance tested by the homogeneity of variance, and was significant different by multiple comparision (F=4. 074, P=0. 026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant ( P = 0. 032, 0. 023, 0. 012 ). Altman- Bland analysis showed that the three methods were not consistent with each other.?CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A - scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.

Background There are a lot of studies about the carrier of corneal endothelial transplantation,but the best carrier has not been defined.Objective This study was to investigate the biocompatibility of chitosan carrier with rabbit corneal endothelium in vivo.Methods Fresh eye-balls were obtained from 10 New Zealand white rabbits.Rabbit corneal endothelial cells (CECs) were isolated and cultured on chitosan carrier in vitro.The morphology and density of rabbits CECs were observed every day,and the expressions of fibronectin (FN),collagen-1 (Coil-I) and Zonula occludens 1 (ZO-1) were detected by immunoinfluorescence.The morphology and ultrastructure of CECs were observed under the scanning and transmission electron microscope.Chitosan carrier with CECs was implanted into the anterior chamber of the left eyes in ten healthy New Zealand white rabbits,and only paracentesis of anterior chamber was performed in the right eyes as controls.The inflammation of ocular anterior segment was examined under the slit lamp microscope,and corneal thickness was measured 1 week,4 and 8 weeks after operation.Corneal endothelium cell density and morphology were examined under the corneal endothelial microscope at postoperative 2 weeks.Corneal samples were collected for the regular histopathological examination to observe the inflammatory reaction at postoperative 1 month and 3 months.Paired t test was used for statistical analyses between the control group (left eyes) and the experimental group (right eyes).The use and care of the animals followed the Statement of ARVO.Results CECs formed an intact monolayer of cells with the uniform shape and size on the chitosan membrane after incubated for 5 days.The cells reached confluence of 90％ 7 days after cultured with the 40％ hexagon cells.Under the scanning electron nicroscope,rabbit CECs showed the round or polygon in the shape with the microvillus on the cell surface.The cells connected closely by desmosome.The processes,pseudopodiums and microvillus on the cellular surface,vacuole in the cytoplasm,expanded endoplasmic reticulum with ribosome and abundant chromatin were exhibited under the transmission electron microscope.The immunofluorescence examination revealed the positive expressions of FN,Coll-Ⅰ and ZO-1 in the CECs on the chitosan carrier.In the in vivo experiment,the exudation in the anterior chamber and corneal edema were seen under the slit lamp microscope 3 days after implantation of chitosan carrier with CECs.However,the inflammation was gone 14 days after operation.The differences of the corneal thickness were no significant between the experimental group and the control group 1 week and 4,8 weeks after operation (t =1.377,P=0.265;t =1.795,P=0.165 ; t =0.390,P =0.760).In addition,no significant differences were found in the CECs density and the hexagon cells rate between the two groups(P =0.365,0.062).The histopathological examination showed that the inflammatory cells around the chitosan membrane were disappeared 3 months after operation and showed a good corneal structure.Conclusions Chitosan carrier has a good biocompatibility with rabbit CECs and anterior chamber,and it may be a potentially good carrier for CECs transplantation.

To improve ethanol production in Saccharomyces cerevisiae,an integration plasmid pUPGKAT with PGK promoter(phosphoglycerate kinase promoter),adh1 gene(the coding sequences of alcohol dehydrogenaseⅠ) and CYC1 terminator(Cytochrome c transcription terminator) was constructed.Firstly,a fusion fragment composed of PGK promoter and adh1 gene was generated by over lap extension PCR and ligated into pUG6 resulting in plasmid pUPGKA.Subsequently,CYC1 termi nator was amplified from pSH65 by PCR and ligated to the SpeⅠand SacⅡrestriction site of pUPGKA.To integrate PGK-adh1-CYC1 into S.cerevisiae genome,pUPGKAT was digested by TthⅢⅠand the lin-earized plasmid was used to transform S.cerevisiae YS2-△adh2(adh2 disrupted strain) by lithium acetate method.The yeast mutant YS2-△adh2-adh1 which had the adh1 gene placed under the PGK promoter and harbored the adh2 deletion was constructed.Anaerobic fermentation showed overexpression of adh1 by PGK promoter resulted in a 8.84% higher ethanol production compared to YS2-△adh2.

The mechanism of chromium accumulation and microstructure transformation of the fused yeast were studied in this paper.The result showed that the process of Cr6+ reduction and adsorption was accom-panied by the H+ consumption.The main adsorptive groups on the strain surface included amino,hydroxyl,phosphate group and amide,among which phosphate group played vital role in the chromium accumulation.The removal rate of chromium and reduction rate of hexavalent chromium declined 70% and 46%,respec-tively,when phosphate group was masked.During the adsorption process the chromium ions complexed on the surface of fused yeast was transported into the cell wall and combined with inclusion to form steady spe-cies and this took 90 min to reach the equilibrium.The biosorption and reduction of Cr on the cell surface would alter microstructure of cell surface,reduce cell membrane potential and increase cell membrane per-meability.
