This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

Objective To determine the involvement of DNA demethylation in tumor necrosis factor-α(TNF-α)-induced matrix metalloproteinase 9 ( MMP9) expression in human epidermal keratinocytes. Methods Real-time RT-PCR, Western blot, and enzyme-linked immuno sorbent assay (ELISA) were performed to determine the mRNA and protein levels of MMP9 after human keratinocyte cell line (HaCaT) cells were treated with 10 ng/ ml TNF-α or 2. 5 μmol/ L DAC/ 300 nmol/ L TSA. Bisulfite sequencing PCR ( BSP) and Methylation-sensitive high-resolution melt analysis ( Ms-HRM) were used to detect significantly differentially demethylated CpG sites in the human MMP9 promoter region in cells exposed to TNF-α. Different sites methylation constructs of promoter-luciferase reporter gene were made to detect the influences of site-specific DNA demethylation on transcription activity of MMP9 promoter. Results Compared with PBS-treated control, TNF-α significantly increased the expression of MMP9 in HaCaT cells for indicated culture duration ( P < 0. 05 ). Real time PCR, Western blot, and ELISA analysis demonstrated that the mRNA and protein levels of MMP9 were increased initially, followed by a decline with prolonged incubation time. After TNF-α treatment, varied degrees of DNA demethylation occurred at 10 CpG sites in the promoter of MMP9, and the changes at the -36 bp site were statistically significant (P<0. 05). The demethylation at the -36 bp site greatly increased the transcription activity of MMP9. Conclusion TNF-α promotes MMP9 expression in HaCaT cells through inducing -36 bp site DNA demethylation on the promoter of MMP9.

OBJECTIVETo study the hepatitis B virus (HBV) genotype and its relation to clinical degree and responsiveness to antiviral therapy on hepatitis in order to guide the clinical therapy.

METHODSWe amplified HBV S gene by polymerase chain reaction (PCR), using the second-round PCR product, which was digested by restriction fragment length polymorphism (RFLP). This genotype method was designed under the analysis of the restriction fragment length polymorphism and using the restriction enzymes that identified the genotype-specific sequences. Five restriction enzymes, Hph I , Nci I , Alw I, Ear I and NlaIV, were identified in genotype-specific RFLP from the S gene region. Representative sequences from the S genome region of each HBV genotype were aligned to show the restriction sites by the five restriction enzymes. The amplified S gene nucleotide sequences were sequenced by dideoxy-chain-termination method and the corresponding amino acid sequence was deduced using DNASIS software. Later, they were genotyped by comparing to representative S gene sequences obtained from GenBank. This confirmed the results of RFLP HBV genotyping methods, coincident with that of S gene sequence.

RESULTSGenotypes A, B, C, D were classified in 216 patients with HBV and DNA positive. The results showed that: 1 case (0.46%) of genotype A, 19 cases genotype B (8.8% ), 175 genotype C (81.02%) and 21 genotype D (9.72%). A total of 86 patients in the hospital were divided into either genotype C cases (69) or non-genotype C cases (17).

CONCLUSIONGenotype C was the major genotype in Changchun. Among HBV patients, type C was 80.95%, followed by genotypes B and D. Both hepatocellular carcinoma and liver cirrhosis showed relations with genotype C.

The influences of the calmodulin antagonist chlorpromazine (CPZ), and calcium chanmel blocker nimodipine (NLMO) and their combination on cadmium (Cd) poisoning of mice were studied.A series of biochemical parameters including urinary enzyme activities, blood and urine Cd levels, metallothionein (MT) contents in liver and kidney, hepatic ultrastructure and Ca2+ -Mg2- AT Pase activitv in erythrocyte membrane were determined. Animal models for Cd poisoning were established by peritoneal injection of 1/5 LD50 CdCl2. The experimental groups were protected by administration of CPZ, NIMO and CPZ and NIMO in combination I h before the injection of CdCl2. Five days later, samples were collected for analysis. The data showed that CPZ could protect kidney tissue against Cd-induced damage, as the urinary y-glutamyl-traspeptidase (γ-GT) and N-acetyl-β-D-glucosaminidase (NAG) activities were reduced significantly. There was neither evidence of the protective effect of NIMO on kidney tissue nor an indication of a synergistic effecf of CPZ and NIMO.Both CPZ and NIMO showed a considerable protective effect against the decrease in Ca2+ -Mg2+ AT-Pase activity, and a synergistic action was observed. Cd content in blood was reduced significantly by CPZ or the combination of CPZ and NIMO, but elevated by NIMO. Both CPZ and NIMO considerably increased MT contents in livers and kidneys and ameliorated damaged to the hepatic ultrastructures caused by Cd. The results indicated that these inhibitors could protect mice against the toxic effects of Cd in liver and kidney tissues, while CPZ was more efficient than NIMO. The combination of CPZ and NIMO excrted a synergistic action. The protective action of these two drugs might be relevent to the function of MT.

In order to explore the dormancy physiological and biochemical mechanism of Paris seeds, the seed embryo growth courses, and the dynamic change of 5 enzymes, include SOD, POD, CAT, MDH, G-6-PDH were measured during variable temperature stratification. The results indicated that Paris seeds embryo grew quickly after 40 d in warm-stratification (18 ± 1) °C, at the meantime the metabolic activity was significantly strengthened. These facts showed that Paris seeds turned into physiological after-ripening process. After 60-80 d, the morphological embryo after-ripping process basically completed, and the following cold-stratification (4 ± 1) °C furthered Paris seed to finish physiological after-ripening. After 40 d, the activity of MDH decreased while G-6-PDH increased significantly. This showed that the main respiratory pathway of seed changed from TCA to PPP, which benifited breaking seed dormancy. In the whole period of stratification process, the activity variation of SOD and CAT was insignificantly and the activity of POD was enhanced significantly after shifting the seed in cold stratification process. This showed that SOD, CAT had no direct effects on breaking Paris seed dormancy but keeping the seed vigor, while the POD might involve in the process of Paris seed dormancy breaking.
