RESUMEN
BACKGROUND: Proteomics is a well studied research method, but its application in the non-surgical treatment of lumbar intervertebral disc protrusion (LIDP) is little reported. OBJECTIVE: To screen the differentially expressed proteins in patients with LIDP but without blood stasis before and after non-surgical treatment by proteomics. METHODS: Sixty patients with LIDP but without blood stasis were selected, and treated with non-surgical treatment for 4 weeks. The differentially expressed proteins were screened and identified by iTRAQ combined with LC-MS/MS. The bioinformatics analysis of the identified proteins was carried out, and the curative effectiveness was investigated. RESULTS AND CONCLUSION: Compared with those before treatment, the Visual Analogue Scale scores were significantly (P ＜ 0.05), the Japanese Orthopedic Association scores were significantly increased decreased (P ＜ 0.05), and the excellent and good rate reached 95.0% post-treatment. A total of 300 differentially expressed proteins were screened and 25 significantly expressed proteins were identified (P ＜0.05). Bioinformatics analysis revealed that nine of the significantly expressed proteins were enriched to 15 KEGG signaling pathways. These results suggest that the use of Western medicine non-surgical treatment for the LIDP without blood stasis can achieve satisfactory results. Besides, complement C1qA, cDNA protein (FLJ60724), complement C4B frameshift mutation, cDNA protein (FLJ53025), mannose binding protein C, apolipoprotein B, hemoglobin α-1 globin chain variant, hemoglobin β subunit and cDNA protein (FLJ76254) may be the potential serum markers of the non-surgical treatment for the LIDP without non-blood stasis.
RESUMEN
Objective To study the correlation between single nucleotide polymorphisms of -238,-308 G/A in promoter region of tumor necrosis factor -?(TNF-?) gene and the type of juvenile idiopathic arthritis (JIA).Methods Clinical data and blood preparation of 127 children with JIA and 106 healthy children were evaluated.Subgroups of JIA were defined according to the Edmonton criteria.The -238 G/A and -308 G/A polymorphisms in DNA analysis in this study were extracted from the whole blood.The restricted fragment length polymorphisms were determined in the cases of all JIA children and control group.Results 1.The TNF-?-238 G/A allele frequencies of JIA group and control group:allele frequency of JIA group was 92.9% and 7.1%,and the control group was 95.3% and 4.7%.The distribution of allele frequencies was no significantly different between JIA group and control group(?2=1.149 P=0.284).But there were significant difference between polyarticular JIA (RF negative) and control group(?2=7.621 P=0.006).2.The TNF-?-308 G/A allele frequencies of JIA group and control group:allele frequency of JIA group was 94.1% and 5.9%,the control group was 95.3% and 4.7%.The distributions of allele frequencies was no significantly different between JIA group and control group(?2=0.322 P=0.571).There were significantly difference between polyarticular JIA (RF negative) and control group (?2=7.621 P=0.006).Conclusions The TNF-?-238,-308 polymorphisms of A in the-238 and-308 TNF-? gene are important to the joint destruction of JIA.The study will be beneficial to provide indirect support to the application of anti-TNF drugs to the treatment of JIA.
