基于免疫级联反应的蚕蛹浆比色法在关节假体周围感染精准诊断中的实验研究北大核心CSCD

目的探讨蚕蛹浆(silkworm larvae plasma,SLP)比色法在关节假体周围感染(periprosthetic joint infection,PJI)精准诊断中的应用价值。方法取90只健康雄性新西兰大白兔,采用Swanson假体行膝关节置换手术;然后根据致病菌不同随机分为3组:A组(金黄色葡萄球菌组)、B组(表皮葡萄球菌组)及C组(大肠埃希菌组),每组30只。术后第3天膝关节腔内注射1 mL不同浓度致病菌制备PJI模型。分别于接种菌液前及接种后7、14、21 d取样进行检测,参照2018年PJI费城国际共识诊断标准首先判定并计算3组实验动物的造模成功率,并采用SLP比色法计算其在PJI精准诊断中的敏感性、特异性、阳性预测值、阴性预测值和诊断效率。结果接种菌液21 d时,A、B、C组分别有26、18、23只实验动物诊断为感染,造模成功率分别为86.7%、60.0%、76.7%,3组间比较差异无统计学意义(χ^(2)=5.724,P=0.073)。PJI比色法结果显示,A组在7 d时出现1只假阳性动物(特异性75.0%),随时间推移(14、21 d)SLP的特异性升至100.0%;14、21 d,另出现了1只假阴性动物(敏感性由100.0%降至96.2%)。B组在7 d时出现1只假阳性动物(特异性91.7%),随着时间推移特异性回升至100.0%;在14、21 d时分别出现1只和4只假阴性动物(敏感性分别为94.4%及83.3%)。C组在7 d时有2只假阳性动物(特异性71.4%),随后回升至100.0%。A、C组在21 d时诊断效率极高(96.7%和100.0%);即使面对B组低毒力的表皮葡萄球菌,21 d时SLP的诊断效率也可保持在90.0%;总体诊断效率很好(95.6%)。结论 SLP比色法诊断PJI具有较高的敏感性、特异性以及诊断效率,是一种极具潜能的PJI诊断方法。     

Analysis of pelvic compensation for dynamic sagittal imbalance using motion analysis

To analyze pelvic compensation during walking in patients with severe sagittal plane deformity by using motion analysis. A total of 44 patients with sagittal plane deformity who were scheduled to undergo surgery were included. Motion analysis was performed 3 consecutive times during walking to estimate the anterior pelvic tilt (Ant-PT) angle, trunk kyphosis (TK) angle, and distance of the center of gravity (CoG) from the center of mass (CoM) of the pelvic segment, and hip and knee joint angles during gait. The patients were classified into Ant-PT+/Ant-PT−, TK+/TK−, and CoG+/CoG− groups according to the changes in Ant-PT angle, TK angle, and distance of the CoG from the CoM of the pelvic segment. Increases and decreases in the values of the variables from the first trial to the third trial were indicated with “+” and “−” signs, respectively. The mean Ant-PT angle, TK angle, and distance of the CoG from the CoM of the pelvic segment increased progressively, and the differences in the values of these variables from the first to the third trials were statistically significant (P = 0.046, P = 0.004, and P = 0.007 for the Ant-PT angle, TK angle, and distance of the CoG from the CoM of pelvic segment, respectively). Among the 44 patients, 27 and 34 were classified into the Ant-PT+ and CoG+ groups, respectively. Older age and higher body mass index (BMI) were significantly associated with the Ant-PT+ group. The CoG+ group demonstrated a significantly higher height and weight than the CoG− group. Higher BMI, height, and weight are risk factors for progressive worsening of dynamic sagittal imbalance.
