Objective To translate and revise the Individualized Care Scale-Patient Version(ICS-P) into Chinese,then to assess the reliability and validity of the Chinese version of the Individualized Care Scale-Patient Version (C-ICS-P).Methods Standard forward-back translation techniques were used in the translation of the ICS-P according to the Brislin translation model.Cross-cultural revision of the translated ICS-P was carried out through group discussion and pretesting.Totally 223 patients were recruited through convenience sampling method from a tertiary hospital in Changsha and investigated using general information questionnaire and the C-ICS-P,and its reliability and validity were assessed.Results The C-ICS-P contained two subscales,and both C-ICS-P-A and C-ICS-P-B contained 3 factors explaining 61.330％ and 65.263％ of the total variance.The dimensions of C-ICS-P-A were clinical characteristics (6 items),personal life characteristics (4 items) and participation willingness (5 items);the dimensions of C-ICS-P-B were clinical care (6 items),personal life care (4 items) and decisional control over care (5 items).The Cronbach's α coefficients of C-ICS-P-A and its dimensions were 0.897,and 0.730～0.774;the Cronbach's α coefficients of C-ICS-P-B and its dimensions were 0.909,and 0.688～0.754.Split-half reliability was 0.856 for C-ICS-P-A and 0.688～0.754 for its dimensions;split-half reliability was 0.889 for C-ICS-P-B and 0.750～0.758 for its dimensions.Analysis of content validity of the C-ICS-P indicated that I-CVI was at least 0.83,S-CVI was 0.943.Conclusion The reliability and validity of C-ICS-P are satisfactory and well meet the requirements of psychological measurement,indicating C-ICS-P is a reliable and valid instrument in the context of Chinese culture.

Objective To construct five shRNA-expression plasmids and to investigate the expression of Smad2 in TGF-?/ Smads signal transduction treated with shRNA-expression plasmid.Methods Five shRNA-Smad2 DNA sequences from mRNA sequence of mouse Smad2 gene were designed and synthesized.DNA oligonucleotides encoding an appropriate shRNA were inserted to shRNA expression vector respectively.Five shRNA-Smad2 expression plasmids were obtained and then transfected into NIH/3T3 cells.The suppressed expression of Smad2 was assessed by RT-PCR and Western-blotting.Results The shRNA-expression plasmid numbered 2.4 could markedly reduce the expression of Smad2.The suppression effect of the RNAi-pool composed of four different plasmids was more obvious than that of any single.Conclusion The shRNA-expression plasmids were successfully constructed,which could specifically and effectively suppress the expression of Smad2.The method of using a mixture of RNAi plasmids to improve the RNAi efficiency was established.

The ompA gene of Chlamyia psittaci in cows was amplified by PCR with primers designed based on those reported in GenBank.The amplified ompA gene was inserted into the bacterial plasmid vector pGEX-4T-1 and then transformed into E.coli BL21(DE3) with IPTG induction. The gene was derived from plasmid pMD18-T vector and then sequenced.It was demonstrated that this recombinant fusion protein of approximately 68kD in molecular mass was highly expressed in inclusion body and more pure proteins would be produced after purification.The fusion protein specifically reacted with positive sera of bovine Chlamydia as demonstrated by Western blotting. These results indicate that this recombinant fusion protein shows good reactivity and could be used to develop the diagnostic kit for bovine Chlamydia and genetic engineering vaccine.

Objective Based on the Integrated Theory of Health Behavior Change(ITHBC),the influencing factors of home medication safety were explored in patients with chronic heart failure(CHF).Methods This qualitative de-scription,involving a semi-structured in-depth interview of 22 CHF patients based on purposive sampling,was con-ducted from December 2022 to May 2023,at 3 hospitals in Changsha,Hunan.NVivo 11.0 software was used to or-ganize and code data,and content analysis was performed to analyze data.Results Totally 9 generic categories be-longing to 4 categories were extracted.These were knowledge(knowledge of disease and knowledge of medication safety),attitude and belief(attitude towards diseases and medication belief),self-regulation(participation in medica-tion safety self-management and growing through experience),and social facilitation(hospital consultation services,family support and objective situation interference).Conclusion Knowledge,belief,self-regulation and social facili-tation were interrelated to influence medication safety behavior of patients with CHF at home.Medical workers,family members and society should work together to provide medication safety information,create a supportive envi-ronment,focus on improving patients'awareness and ability of self-regulation,strengthen their belief in taking medi-cation,and ultimately ensure the home medication safety for CHF patients.

Next-generation sequencing has yielded a vast amount of cattle genomic data for global characterization of population genetic diversity and identification of genomic regions under natural and artificial selection. However, efficient storage, querying, and visualization of such large datasets remain challenging. Here, we developed a comprehensive database, the Bovine Genome Variation Database (BGVD). It provides six main functionalities:gene search, variation search, genomic sig-nature search, Genome Browser, alignment search tools, and the genome coordinate conversion tool. BGVD contains information on genomic variations comprising ～60.44 M SNPs, ～6.86 M indels, 76,634 CNV regions, and signatures of selective sweeps in 432 samples from modern cattle worldwide. Users can quickly retrieve distribution patterns of these variations for 54 cattle breeds through an interactive source of breed origin map, using a given gene symbol or genomic region for any of the three versions of the bovine reference genomes (ARS-UCD1.2, UMD3.1.1, and Btau 5.0.1). Signals of selection sweep are displayed as Manhattan plots and Genome Browser tracks. To further investigate and visualize the relationships between variants and signatures of selection, the Genome Browser integrates all variations, selection data, and resources, from NCBI, the UCSC Genome Browser, and Animal QTLdb. Collectively, all these features make the BGVD a useful archive for in-depth data mining and analyses of cattle biology and cattle breeding on a global scale. BGVD is publicly available at http://animal.nwsuaf.edu.cn/BosVar.

Objective:To explore the association between polymorphisms of transforming growth factor-β(TGF-β)signaling pathway and non-syndromic cleft lip with or without cleft palate(NSCL/P)among Asian populations,while considering gene-gene interaction and gene-environment interaction.Methods:A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium,which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P.After stringent quality control measures,343 single nucleotide polymorphism(SNP)spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS)dataset for further analysis.The transmission disequilibrium test(TDT)was used to test for SNP effects.The conditional Logistic regression models were used to test for gene-gene interaction and gene-environment interaction.Environmental factors collected for the study in-cluded smoking during pregnancy,passive smoking during pregnancy,alcohol intake during pregnancy,and vitamin use during pregnancy.Due to the low rates of exposure to smoking during pregnancy and al-cohol consumption during pregnancy(＜3％),only the interaction between maternal smoking during pregnancy and multivitamin supplementation during pregnancy was analyzed.The threshold for statistical significance was rigorously set at P=1.46 × 10-4,applying Bonferroni correction to account for multiple testing.Results:A total of 23 SNPs in 4 genes yielded nominal association with NSCL/P(P＜0.05),but none of these associations was statistically significant after Bonferroni's multiple test correction.How-ever,there were 6 pairs of SNPs rs4939874(SMAD2)and rs1864615(TGFBR2),rs2796813(TGFB2)and rs2132298(TGFBR2),rs4147358(SMAD3)and rs1346907(TGFBR2),rs4939874(SMAD2)and rs1019855(TGFBR2),rs4939874(SMAD2)and rs12490466(TGFBR2),rs2009112(TGFB2)and rs4075748(TGFBR2)showed statistically significant SNP-SNP interaction(P＜1.46 × 10-4).In contrast,the analysis of gene-environment interactions did not yield any significant results after being cor-rected by multiple testing.Conclusion:The comprehensive evaluation of SNP associations and interac-tions within the TGF-β signaling pathway did not yield any direct associations with NSCL/P risk in Asian populations.However,the significant gene-gene interactions identified suggest that the genetic architec-ture influencing NSCL/P risk may involve interactions between genes within the TGF-β signaling path-way.These findings underscore the necessity for further investigations to unravel these results and further explore the underlying biological mechanisms.

To translate and revise the Medication Literacy Assessment in English (MedLitRxSE-English) and evaluate its validity and reliability.
 Methods: We introduced MedLitRxSE-English from abroad. According to the principles of Brislin and culture adjustment, we revised it as a Chinese edition. Using random sampling method, from Oct, 2014 to Jan, 2015, 461 non-hospitalized patients from the outpatient departments of the top three hospitals in Changsha city were investigated. The reliability and validity of the scale was tested.
 Results: The test-retest reliability of the Chinese version for medication literacy scale was 0.885; the split reliability was 0.840; K-R was 0.820; the correlations between the assessment of medication literacy and the corresponding items were 0.427-0.587; the confirmatory factor analysis revealed overall good fit. Root mean square error of approximation (RMSEA), χ2/df, goodness of fit index (GFI) and comparative fit index (CFI) was 0.08, 3.06, 0.91 and 0.94, respectively. 
 Conclusion: The Chinese version for the assessment of medication literacy is in good reliability and validity, and it can be used to evaluate the medication literacy in our country.
