胚胎颅骨骨膜移植修复髋关节软骨大面积缺损

１９９０年５月～１９９４年４月，对４２例（４７个髋）关节软骨全厚缺损患者采用冷冻保存胚胎颅骨骨膜移植进行修复，其中１４例股骨头骨质Ⅳ期坏死者，同时施行带旋髂深血管蒂髂骨植骨。对３４例（３８个髋）进行了２年～６年（平均４０个月）随访。结果表明，按照吴之康髋关节人工置换术后疗效评定标准，优良２５例，很好５例，好３例，尚可１例。认为，与自体移植物修复关节软骨大面积缺损相比，这种方法无附加损伤，具有移植材料、形态与股骨头相似等特点，是治疗髋关节软骨大面积缺损的一种有效方法。

低位直肠癌保肛术后低位前切综合征发生的危险因素分析

目的探讨低位直肠癌患者行保肛术后出现低位前切综合征(LARS)的危险因素。方法收集2015年1月-2019年12月在本溪市中心医院行保肛手术治疗的低位直肠癌患者421例,对患者的临床资料进行回顾性分析,并依据患者术后是否发生LARS分为LARS组106例和非LARS组315例、分析LARS发生的危险因素。结果单因素Logistic回归分析显示,年龄,术前放宁、术后恢复时间、坐骨棘间径是LARS发生的危险因素(P<0.05)。多因素Logistic回归分析显示,术前放疗.术后恢复时间、坐骨棘间径是LARS发生的危险因素(P<0.05)。结论对于低位直肠癌行保肛手术治疗患者,术前放疗.术后恢复时间.坐骨棘间径与术后LARS的发生密切相关,对存在上述危险因素的低位直肠癌患者,术前应采取针对性预防措施,或采取其他术式治疗。

Periosteal PTHrP regulates cortical bone modeling during linear growth in mice

The modeling of long bone surfaces during linear growth is a key developmental process, but its regulation is poorly understood. We report here that parathyroid hormone‐related peptide (PTHrP) expressed in the fibrous layer of the periosteum (PO) drives the osteoclastic (OC) resorption that models the metaphyseal–diaphyseal junction (MDJ) in the proximal tibia and fibula during linear growth. PTHrP was conditionally deleted (cKO) in the PO via Scleraxis gene targeting (Scx‐Cre). In the lateral tibia, cKO of PTHrP led to a failure of modeling, such that the normal concave MDJ was replaced by a mound‐like deformity. This was accompanied by a failure to induce receptor activator of NF‐kB ligand (RANKL) and a 75% reduction in OC number (P ≤ 0.001) on the cortical surface. The MDJ also displayed a curious threefold increase in endocortical osteoblast mineral apposition rate (P ≤ 0.001) and a thickened cortex, suggesting some form of coupling of endocortical bone formation to events on the PO surface. Because it fuses distally, the fibula is modeled only proximally and does so at an extraordinary rate, with an anteromedial cortex in CD‐1 mice that was so moth‐eaten that a clear PO surface could not be identified. The cKO fibula displayed a remarkable phenotype, with a misshapen club‐like metaphysis and an enlargement in the 3D size of the entire bone, manifest as a 40–45% increase in the PO circumference at the MDJ (P ≤ 0.001) as well as the mid‐diaphysis (P ≤ 0.001). These tibial and fibular phenotypes were reproduced in a Scx‐Cre‐driven RANKL cKO mouse. We conclude that PTHrP in the fibrous PO mediates the modeling of the MDJ of long bones during linear growth, and that in a highly susceptible system such as the fibula this surface modeling defines the size and shape of the entire bone.
