相同骨折分型研究组与对照组患者性别、年龄、骨折部位等一般资料比较，差异均无统计学意义（P>0.05）。 | There was no significant difference between the two groups (P>0.05) in gender, age, fracture site, and other general information. |
术后 1 周内行 CT 扫描并测量双侧胫骨旋转角，计算患侧与健侧的差值，以差值绝对值超过 10° 者定义为胫骨旋转不良。 | The bilateral tibial rotation angles were measured on the CT images within 1 week after operation, and the difference of tibial rotation angle between affected and unaffected sides was calculated.

入选住院SLE患者122例，其中SLE合并肺部感染者21例，合并关节炎者16例，合并肾炎者26例，合并血管炎者10例；另选健康对照者23例。 | A total of 122 SLE patients were enrolled, including 21 with pulmonary infections, 16 with arthritis, 26 with nephritis, 10 with vasculitis, and 23 healthy controls. |
检测所有受试者血清MMP-3、C反应蛋白（CRP）、血清淀粉样蛋白A（SAA）、触珠蛋白（HPT）水平。 | Serum MMP-3, C-reactive protein (CRP), serum amyloid A (SAA), and haptoglobin (HPT) levels were measured in all subjects. |
结果显示，SLE合并肺部感染者[（230.10±44.92）μg/L]、关节炎者[（140.20±20.76）μg/L]、肾炎者[（155.40±23.36）μg/L]血清MMP-3水平高于单纯SLE者[（91.74±10.47）μg/L]。 | The results showed that the levels of MMP-3 in SLE combined with pulmonary infections [(230.10±44.92) μg/L], arthritis [(140.20±20.76) μg/L], nephritis [(155.40±23.36) μg/L] were higher than those in SLE only [(91.74±10.47) μg/L]. |
SLE合并肺部感染者血清MMP-3、CRP[（1.99±1.03）mg/L]、SAA[（92.19±23.93）mg/L]、HPT[（1.42±0.18）g/L]水平高于SLE无肺部感染者[MMP-3为（115.40±8.93）μg/L；CRP为（0.44±0.13）mg/L；SAA为（38.79±8.98）mg/L；HPT为（0.88±0.06）g/L]。 | The levels of MMP-3 [(210.30±45.71) μg/L], CRP [(12.11±5.21) mg/L], HPT [(1.57±0.23) g/L] in active SLE combined with pulmonary infections were higher than those inactive SLE without pulmonary infections including MMP-3 [(124.00±15.22) μg/L], CRP [(7.76±2.96) mg/L], HPT [(0.89±0.09) g/L]. |
提示SLE疾病活动与合并肺部感染时血清CRP、SAA水平升高，血清MMP-3水平在SLE合并肺部感染时升高，因此血清MMP-3联合CRP可能协助鉴别SLE疾病活动与合并肺部感染。 | It suggests that the levels of CRP and SAA are elevated in active SLE with pulmonary infections. Serum MMP-3 in combination with CRP may assist in differentiating from SLE pulmonary infections. |
