Objective To analyze the sensitivity of clinical isolates of Candida albicans to flucona- zole,to detect mutations in their ERG11 genes,and to investigate the correlation between ERG11 gene mutation and resistance to fluconazole.Methods Candida albicans was identified from clinical isolates of Candida spp..The sensitivity to fluconazole was detected in vitro by microdilution-basesd method and Rosco tablets method.Three pairs of primers were designed to amplify three fragments of ERG11 gene(483 bps, from 295 bp to777 bp;482bps,from 723 bp to 1204 bp;489 bps,from 1179 bp to 1667 bp)after the extracting of genomic DNA.PCR products were sequenced.Results Eighty clinical isolates of Candida spp.were collected,which included 52 isolates of Candida albicans,all of which were sensitive to flucona- zole.Nineteen mutations were detected in ERG11 gene of 5 fluconazole-sensitive clinical isolates.Of the 19 mutations,14 were samesense mutations,and the remaing 5 missense mutations(T495A,A530C, G640A,A945C and G1609A),resulting in amino acid substitution D116E,K128T,E165K,E266D and V488I,respectively in lanosterol 14 alpha-demethylase.E165K was a novel mutation.Conclusions The clinical isolates of Candida albicans were highly sensitive to fluconazole;E165K and V488I might not lead to the resistance of Candida albicans to fluconazole.

This study was aimed to analyze the formulas and classify the treatment of chronic kidney disease (CKD) by Dr. Huang Chunlin based on the data mining method. A total of 63 CKD outpatients' medical records by Dr. Huang were collected. And 226 formulas prescribed in the medical records were put in the Traditional Chinese Medicine Inheritance Support System (TCMISS). Data mining techniques were applied in the study of as-sociation rule mining algorithm and complex system entropy cluster, the usage frequency and the correlation of each single Chinese medicinal in order to sort out the prescription pattern of CKD. The results showed that to for-tify the spleen and tonify the kidney were found to be the basic method of CKD treatment . Through the applica-tion of TCMISS, the Chinese medicinals used in Dr. Huang's CKD treatment were Astragalus root, Eucommia, Epimedium, Cuscuta, Agastache, Danshen Root, Ligustrum. It was concluded that the TCMISS is of great value in the summarization of clinical experiences of well-known TCM doctors.

This paper is to report the polymorphism of raw materials of clopidogrel bisulfate at home and abroad. By the analysis of Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffraction (p-XRD), samples are roughly classified into two groups, except one patent material. And the differential scanning calorimeter (DSC) examination showed more detailed information for these materials. The results of the study could provide comprehensive basis for the quality evaluation of clopidogrel bisulfate.

Objective To investigate the effect of knockdown or overexpression of G6PD on proliferation, growth and migration of human hepatocellular carcinoma cell PLC/PRF/5. Methods Lentivirus-mediated knock-down or overexpression of G6PD was achieved in human hepatocellular carcinoma cell line PLC/PRF/5. RT-PCR and Western blotting assay were used to detect the overexpression or knockdown of G6PD.Cell proliferation and mi-gration curves were recorded by real-time cell analysis system(RTCA),the cell proportion in the DNA replication phase can be directly displayed with EDU experiment,cell growth ability was detected by colony forming assay. Results The doubling time of cells in G6PD knockdown group was longer than that of the control group,and the cell growth rate decreased significantly,the proportion of cells in proliferative phase(43.2%)was lower than that in the control group,but the rates colony formation and migration were significantly decreased(P<0.05,respective-ly),and the migration curves separated apparently.While no significant differences in proliferation,growth and mi-gration of PLC/PRF/5 cells were found between the over-expressed strain and the control group. Conclusion The reduction of G6PD expression in HCC cells inhibits the proliferation and growth of HCC,which may lay a foun-dation for the further study of the pathogenesis and treatment of HCC.

G mutation were intervened and avoided the occurrence of deafness,1 babies with 235delC homozygote was confirmed severe sensorineural hearing loss in the hearing screening.Conclusion Newborn gene screening make up the defects of missed diagnosis in simple hearing screening in finding the newborn babies with late-onset deafness or the high risk as well as the pathogenic carriers.So the hearing and gene screening were necessary in the current situation,and this screening strategy would be developed further in Henan province.

Chronic kidney disease was closely related with unhealthy lifestyle; therefore a strategy focused both on daily life and medical process, like the Expert Patients Program, was of great value in the prevention and treatment of chronic kidney disease. In China, however, obstacles still existed in the process of implementing the program. Adding traditional Chinese medical interventions to the program assisted both patients and physicians to understand and to accept this new trend in management of chronic disease better. The combination with traditional Chinese medical interventions showed a solution for successfully implementing the Expert Patients Program and provided a new strategy for prevention and control of chronic kidney disease.
