Abstract Objective: To identify the association between the interleukin (IL) 6 (IL-6) rs1800795 (-174 G>C), IL-8 rs4073 (-251T>A), and matrix metalloproteinase-13 (MMP-13) rs2252070 (-77G>A) gene polymorphisms and knee osteoarthritis (KOA) susceptibility in the Chinese Han population. Methods: Genomic DNA was extracted from a total of 400 KOA patients and 400 healthy subjects. Sanger sequencing was performed to determine the genotypes of the IL-6 rs1800795 (-174 G/C), IL-8 rs4073 (-251A/T), and MMP-13 rs2252070 (-77A/G) loci. The mRNA expression levels of IL-6, IL-8, and MMP-13 in osteoblasts and the protein expression levels of IL-6, IL-8, and MMP-13 in the synovial fluids of KOA patients were analyzed. Results: The recessive model of IL-6 rs1800795 locus was found to be associated with KOA risk (adjusted odds ratio (OR) = 1.657, 95% confidence interval (CI) = 1.396–1.866, P<0.001). The IL-8 rs4073 locus dominant and recessive model showed no significant association with KOA risk (P>0.05). The dominant and recessive models of the MMP-13 rs2252070 locus showed higher risk for developing KOA (dominant model: adjusted OR = 1.271, 95%CI = 1.095–1.480, P=0.001; recessive model: adjusted OR = 1.361 95%CI = 1.151–1.569, P<0.001). The G>C mutation in IL-6 rs1800795 and the G>A mutation in MMP-13 rs2252070 were associated with significantly higher KOA disease severity. The G>C mutation in the IL-6 rs1800795 locus was associated with up-regulation of IL-6 expression. The G>A mutation in the MMP-13 rs2252070 locus was associated with up-regulation of MMP-13 expression. Conclusion: The IL-8 rs4073 (-251T>A) mutation was not associated with KOA susceptibility. The IL-6 rs1800795 (-174 G>C) and MMP-13 rs2252070 (-77G>A) mutations were associated with KOA susceptibility, increased disease severity, and up-regulation of IL-6 and MMP-13 expression levels.

Objective To investigate associations between single polymorphisms (SNPs) rs1800469 and rs1982073 in the transforming growth factor-β1 gene ( TGF-β1) and knee osteoarthritis (OA) susceptibility in a Chinese Han population. Methods TGF-β1 rs1800469 and rs1982073 were genotyped in patients with knee OA and age- and sex-matched OA-free controls from a Chinese Han population. The association was further analyzed according to gender and age. Results A total of 765 patients with knee OA and 780 controls were included. CT and CT + CC genotypes of rs1982073, and variant C, were associated with a significantly increased risk of knee OA. Stratification analysis showed that the association between the OA risk and rs1982073 CT heterozygotes compared with TT homozygotes was stronger in females and those aged >65 years. In contrast, CT, TT, and CT + TT genotypes of rs1800469 were not significantly associated with the risk of knee OA, even after further stratification analysis for gender and age. Conclusions The TGF-β1 rs1982073 T to C change and the variant C genotype may contribute to knee OA risk in the Chinese Han population.

Abstract Background: Handgrip strength (HGS) has been widely studied in clinical and epidemiological settings, but the relationship between HGS and pulmonary function is still controversial. This study analyzed pulmonary function and HGS stratified by sex and age in a healthy Chinese Han population, as well as the associations between HGS and pulmonary function parameters. Methods: HGS was measured by a Jamar dynamometer and pulmonary function was tested using a portable spirometer. Frequencies and variables are presented as percentages and means ± standard deviations, respectively. Chi-square tests were used for comparisons of categorical variables, and Student’s t-tests or Mann–Whitney U-tests were used for continuous variables. Pearson correlation analysis was used between normally distributed variables, and Spearman correlation analysis was used for non-normally distributed variables. Multivariate linear regression models were employed to explore the relationships between HGS and parameters of pulmonary function. The statistical significance was set at p <0.01. Results: Cross-sectional data were available for 1519 subjects (59.0% females, 57.9±13.1 years old). Males had higher average HGS than females (40.2 vs 25.0 kg, p <0.01 ), as well as better pulmonary function. Both HGS and pulmonary function parameters were significantly inversely correlated with age (r ≤ -0.30, p < 0.01). Maximum value of vital capacity (VC max), forced expiratory volume in 3 second (FEV3) and forced vital capacity (FVC) were strongly correlated with HGS among the pulmonary function indices (r=0.72, 0.70 and 0.69, respectively, p <0.001). In multivariate linear regression analysis, HGS and height were positively correlated, while age and pulse pressure were negatively correlated with HGS. In male, FVC, VC max and FEV3 increased by 0.02L, 0.023L and 0.03L in per 1 kg increase in HGS, respectively. The coefficients of HGS in female was smaller than those in male. Conclusions: Both pulmonary function and HGS were inversely correlated with age, and better pulmonary function was associated with greater handgrip strength.
