Objective To investigate the therapeutic effects of Smad7 and urokinase-type plas- minogen activator(uPA)co expression on CCl_4-induced rat liver fibrosis.Methods Forty SD rats were subcutaneously injectied of 40% CCl_4 every three days for 8 weeks.The rats were then divided into model group,AdSmad7/uPA group(injected with AdSmad7/uPA via tail vein),AdSmad7 group(injec- ted with AdSmad7 via tail vein)or AdGFP group(injected with AdGFP via tail vein).Ten healthy rats were served as control.The serum levels of procollagenⅢ(PCⅢ)and laminin(LN)were determined by radioimmunoassay,and the hydroxyproline level in liver tissues were examined by alkaline hydrolysis. The expressions of Smad7 and uPA in tissue were examined by immunohistochemistry and fibrosis area was stained with Sirius red.Results The expressions of Smad7 and uPA protein were significantly higher in AdSmad7/uPA group than that in AdGFP group after 3 days.Serum levels of ALT,AST,PCⅢand LN were significantly decreased in AdSmad7/uPA group compared to Smad7 and AdGFP groups (all P value

Ginsenosides,which belongs to triterpenoid saponins of plant terpenoids,are the main active components of the valuable medicinal herbs ginseng and American ginseng.Recent studies show that ginsenosides have a variety of beneficial effects,including anti-inflamatory,antioxidant,and anticancer effects.Ginsenosides are synthesized by complicated modification of triterpenoid skeleton after cyclization of 2,3-oxidosqualene through triterpene saponin synthesis pathway in which they share common early steps with phytosterols synthesis.It outlines recent advances for the biosynthesis of ginsenosides,the cloning and characterization of genes encoding key enzymes in the pathway and the basal framework of ginsenosides biosynthesis pathway.The prospects of secondary metabolism engineering in the biosynthesis of plant natural products and its application in ginsenosides biosynthesis are also discussed.

Objective To investigate the results of the language rehabilitation through the evaluation of the language comprehension of 75 cases of severe to profound pre -lingually deaf adolescents with cochlear implants . Methods Using evaluation criteria and methods on hearing and speech ability in deafened childrenas a test mate-rial ,and analyzed the outcome of the language comprehension test .Results The comprehension ability of entire pa-tients increased significantly as time went by .The entire comprehension ability was 0 .75y ,1 .45y ,2 .23y ,3 .08y before operations ,and 3 ,6 ,12 months after operations .The younger ,the more significant the improvements .There was no significant difference in rehabilitation outcomes in genders and wearing no hearing aids .Conclusion Cochlear implants can improve the comprehension ability of pre -lingual deaf adolescents ,and the longer they use implants , the better the results .If being implanted at younger age ,the improvement will be more significant .Patients who were beyond the best age were advised to get implant as soon as possible .

Objective To investigate the clinical pathologic significance of lymphangiogenesis in in colorectal cancer. Methods New lymphatic-specific markers D2-40 was used immunohistochemically to detect the lymphatic vessel density(LVD) in the intratumoural and peritumoral areas, and in normal tissue from 96 cases of colorectal cancer, which were analyzed with clinical pathologic parameters of those colorectal cancer. Results Significandy higher LVD was found in the intratumoural area(14.5±2.4), when compared with normal(5.9±1.1)and peritumoural areas(6.7±1.2) (P<0.01). LVD of the peritumoural area was higher than normal area (P< 0.01). However, peritumoural LVD was associated with both depth of invasion and liver metastasis (r=0.71,0.78 P<0.05), but not associated with tumour size, macroscopic type and lymph-node metastasis (P>0.05). Intratu-moural LVD was not correlated with tumour size, macroscopic type, the depth of invasion,lymph-node metastasis, and liver metastasis(P>0.05). Conclusion Lymphangiogenesis in the peritumoural area may be helpful in evalution of liver metastasis and prognosis.

Glycyrrhizin is the major bioactive compound in Glycyrrhiza uralensis. Farnesyl-diphosphate synthase (FPS) is one of the major enzymes involved in the glycyrrhizin biosynthetic. We cloned the full length of FPS coding sequence based on the transcriptome data of G. uralensis. The FPS gene of G. uralensis (GlyurFPS) is 1029 bp, coding 342 amino acid. The homology between the sequence of its protein and that of the FPS in Cicer arietinum, Medicago sativa, Medicago truncatula, Glycine max, Lotus japonicus was of 94%, 94%, 93%, 93% and 92%, respectively. Plant FPS gene is very conservative, therefore the phylogenetic tree is same with the plant classification consistent.

Objective To investigate the characteristics of falls as an adverse event in the hospitalization of elderly patients taking sedatives and hypnotics drugs.Methods Data of elderly patients treated in Department of General Internal Medicine,Beijing Chaoyang Hospital from July 2011 to July 2015 were collected.All patients were divided into medicine-taking group and non-medicinetaking group according to the history of taking sedatives and hypnotics during the hospital stay.Different characteristics of fall as an adverse event were compared between the two groups,and fall related nursing interventions were presented.Results A total of 3 834 patients were collected for analysis in this study.Of these patients,the fall as an adverse event occurred in 12 cases,the total incidence was 3.1％,in whom 8/638 (12.5％) in medicine-taking group and 4/3196 (1.3％) in nonmedicine-taking group(x2=21.72,P＜0.01).Of 8 cases with the fall as an adverse event in medicinetaking group,the fall occurred in 6 cases(75％)during 24 ∶ 00-6 ∶ 00.However,of 4 cases with the falls in non-medicine-taking group,the fall in 3 cases(75 ％)occurred during 6 ∶ 00-18 ∶ 00.In medicinetaking group,the fall occurred beside their beds in 62.5 ％ (5 cases).And in 37.5 ％ (3 cases)did in their bathrooms.In non-medicine-taking group,the fall occurred in 2 cases (50.0％) beside their beds,in 1 case did in the bathroom,1 case did in the passage.Multiple Logistic regression analysis showed that age ＞ 75 years(OR=1.26,95 ％CI:1.07-1.48),elevated nutritional risk score(NRS-2002 ≥3 scores) (OR=10.92,95％CI:1.79-66.46)and elevated risk for fall or out of bed(risk score ≥18 scores) (OR =19.08,95％ CI:4.02-90.47)were the independent risk factors for falls as an adverse event among medicine-taking group.Conclusions A use of sedatives and hypnotics is related with the increase of fall as an adverse event in elderly patients during a hospital stay.With the aim of preventing or reducing the incidence of fall as an adverse event,nursing interventions should be carried out based on the characteristics of fall as an adverse event in elderly patients taking sedatives and hypnotics.

Codon usage bias is an important characteristic of genetic information transfer in organisms. Analysis of codon usage bias of different species is important for understanding the rules on genetic information transfer. The previous method for analysis of codon usage bias is mainly based on genomic data. However, this method is greatly limited, because the genome sequences of higher organisms are still not available up to now. In this study, we found that we could obtain the same optimal codons of Ganoderma lucidum (Curtis: Fr.) P. Karst based on its whole genomic data or large-scale transcriptomic data from its liquid-cultured hyphae, primordium and fruiting body, separately. This result indicated the feasibility to understand the codon usage bias based on the large-scale transcriptomic data. By calculating the proportion of rare codons of Escherichia coli and Saccharomyces cerevisiae in 26 terpene synthases (TS) of G. lucidum, we found that the rare codons of S. cerevisiae have a higher proportion in TS genes, while the rare codons of E. coli have relatively lower, suggesting that the TS genes of G. lucidum are possibly more difficult to be expressed in S. cerevisiae than in E. coli. Chemical synthesis of TS genes according to the yeast optimal codons will be an effective way to solve the problem on the mismatch of gene codon bias between the foreign genes and the host strain.
