OBJECTIVE:To establish a method for the determination of the content and molar ratio of Ornithine aspartate for in-jection. METHODS:HPLC was performed on the column of Thermo HYPERSIL Aps-2 amino column with mobile phase of aceto-nitrile-0.05mol/L Potassium dihydrogen phosphate solution,the flow rate was 0.9 ml/min,the column temperature was 30℃,the de-tection wavelength was 200 nm,and the injection volume of 20 μl. The results determined by HPLC and potentiometric titration were compared. RESULTS:The linear range of ornithine aspartate was 0.02-10.01 mg/ml(r=0.999 9);RSDs of precision,stabili-ty and reproducibility tests were lower than 2%;recovery was 99.15%-100.15%(RSD=0.35%,n=9). The content of 3 batches of Ornithine aspartate for injection was 100.04%-100.64% and molar ratio was 0.982-0.989. The content is similar to the results de-termined by potentiometric titration with national standards. CONCLUSIONS:The method is simple,accurate,specific and sensi-tive,and suitable for the determination of the content and molar ratio of Ornithine aspartate for injection.

Objective To analyze the prevention and nursing measures of adverse drug reaction in patients with rheumatoid arthritis treated with Tolicizumab.Method The clinical data and nursing measures in 30 patients with rheumatoid arthritis treated with Tolicizumab were reviewed and analyzed.Result All the patients completed the treatment and no infusion reaction was observed in the first 24 hours.Conclusions Comprehensive and intensive assessment is necessary before application of Tocilizumab. Executing standard drug dispensing and injection process,mastering the infusion reaction emergency processing measures and establishing injection related systems are of great significance to observe and treat various adverse reactions in time,ensuring drug effects and safety of the patients.

Objective To analyze the regulation of gene expression by adenosine deaminase RNA specific 1(ADAR1)in cervical cancer cell line Hela using RNA-seq technology and provide theoretical basis for understanding the role of ADAR1 in the occurrence and progression of cervical cancer.Methods RNA-seq sequencing of normal and ADAR1 knockdown Hela cell lines to identify differentially expressed genes.By conducting enrichment analysis using KEGG Pathway,GO cellular,and GSEA,the study analyzes the relevant signaling pathways and biological processes involving ADAR1 in Hela cell lines.Results Differentially expressed genes are mainly enriched in immune and inflammation-related signaling pathways(such as TNF-α/NF-κB,NIK/NF-κB,Jak/Stat-IL-6),Hippo signaling pathway,TGF-β signaling pathway,and are involved in interferon response,cellular amino acid metabo-lism regulation,protein ubiquitination/deubiquitination,viral transcription,and other biological processes.Further analysis of the NF-κB signaling pathway revealed a significant increase in the mRNA expression levels of NF-κB1 and TRAF5 after ADAR1 knockdown.Conclusion ADAR1 may regulate the expression of NF-κB signaling pathway-related factors and thereby regulate the occurrence and development of cervical cancer.

PURPOSE: The purpose of this study is to investigate the impact of transitional care by a nurse-led multidisciplinary team (MDT) on clinical outcomes and quality of life of patients with ankylosing spondylitis. METHODS: A randomized control study design was used. Subjects were allocated randomly to an experimental group and a control group. The experimental group received intensive transitional care by a nurse-led MDT, whereas the control group received routine nursing care. Disease activity, spinal mobility, comprehensive function, health service utilization, and quality of life were assessed at the baseline and at six months with the Bath Ankylosing Spondylitis Metrology Index, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), a health service utilization questionnaire and version 2 of the Short Form-36 health survey. RESULTS: Compared with the baseline, the BASDAI, BASFI, emergency visits, hospitalizations, hospitalization days, and bodily pain, vitality, mental health, total score, and average score of version 2 of the Short Form-36 health survey were improved in the experimental group (p < .05), whereas only bodily pain, vitality, and role-emotional were improved in the control group p < .05). At six months, the experimental group exhibited significantly more improvement on the BASDAI, BASFI, hospitalizations, all domains except Role-physical as well as total score and average score p < .05) compared with the control group. CONCLUSION: A MDT-based nurse-led transitional care improves clinical outcomes and quality of life of patients with ankylosing spondylitis. Future research should be carried out on modes of follow-up and family support.

Objective To investigate the expression of FAM19A4 gene promotor methylation in different cervical lesions and its diagnostic value. Methods 31 cervical cancers cases ,22 HSILs and 23 normal cervical tissues of formalin-fixed and parrffin-embedded specimen diagnosed by pathology were selected. Taqman probe-based quantitative PCR(qPCR)was used to detect the differences of FAM19A4 methylation in different cervical lesions, and then corresponding analyses were made. Results Statistical differences of FAM19A4 methylationrates were observed in cervical caner ,HSIL and normalcervix,respectively96.8%(30/31),72.7%(16/22)and 8.7%(2/23) (P < 0.05 ).FAM19A4 methylation rates increased with severity of cervical lesion (P < 0.05).The methylation rates of FAM19A4 were not statistically different in different clinicopathological characteristics of cervical cancer (P>0.05). Conclusions FAM19A4 gene promoter methylation is probably a specific biomarker of cervical cancer,andmay play a role in the development and progress of cervical cancer,but may not participate in the invasion and metastasis.
