理疗治疗深部炎性肿块的体会

炎性肿块是由于局部血液循环不畅或某些异物刺激引起局部肉芽组织过度增生而形成肿块,使用各种抗生素疗效不明显,改用电脑中频治疗仪进行物理治疗,能促进局部血液循环,疏通经络,增强机体抗病能力,达到肿块散结的临床效果。     

内镜电脑统一命名的基本标准

近年来消化内镜工作者对应用电脑于内镜的检查与诊断产生了极大的兴趣。电脑给内镜有关资料的储存、研究以及统计学的分析带来极大的方便,免去了手工打字与复印等复杂劳动。在全世界已有不少的电脑内镜记录系统,然它们的诊断命名缺乏统一的标准,因此各国内镜学家所收集的资料,因标准不一无法进行对比,造成了结论的不一致。     

准分子激光角膜切削术治疗屈光不正（简称PRK）及其并发症

PRK是一种非接触的电脑控制的眼屈先矫治术．治疗是通过准分子激先去除眼角膜不到十分之一的表层．从而明显地改造了角膜的屈光力，使原来落在视网膜上不清晰的影像变得清晰。至今世界上已有二十多万人接受了此项治疗，效果良好，与其它近视手术如放射状角膜切开术（PK）比较PRK具有预测性高、稳定性强，安全系数大及反应轻．痛苦小、恢复快．治疗范围广。不受人为因素影响的特点，为目前最有效的对近视、远视及散光的治疗方法．不失为摘掉眼镜的最佳选择．

3D打印技术在复杂慢性髋关节假体周围感染中的临床研究

目的 评价3D打印技术在复杂慢性髋关节假体周围感染患者中应用的临床价值。方法 回顾性分析我科2018年1月至2021年12月收治的复杂慢性髋关节假体周围感染患者21例,其中采用常规治疗方案10例为对照组,采用3D打印技术11例为观察组;两组患者均采用初次清创及抗生素骨水泥临时假体植入,待感染控制后二期翻修的治疗方案。观察组所有患者术前均采用3D打印技术等比例重建髋关节模型,根据3D打印模型制定手术计划。分析并记录两组患者两次手术总住院费用、总住院时间、总出血量及输血量及两次手术总时间、总术前等待时间、两组患者初次术前及二期术后髋关节VAS评分及Harris评分、两组患者术中并发症。结果 观察组1例患者由于年龄大且身体条件差未行二期翻修,两组其余所有患者均顺利完成两次手术,术后患者均取得随访。观察组患者总术前等待时间、总住院时间较对照组长,差异有统计学意义(P<0.05)。观察组患者总手术时间较对照组短,差异有统计学意义(P<0.05)。观察组与对照组初次手术术中出血量比较差异无统计学意义(P>0.05),而二期翻修术中出血量比较观察组较对照组少,差异有统计学意义(P<0.05)。两组患者并发症比较观察组较对照组相对较少,但组间比较差异无统计学意义(P>0.05)。两组患者二期手术后髋关节VAS评分及Harris评分均较初次术前明显改善,组间比较差异无统计学意义(P>0.05);而总住院费用观察组较对照组相对较高,但组间比较差异无统计学意义(P>0.05)。结论 3D打印技术在复杂慢性髋关节假体周围感染患者中的应用能减少术中出血量、减少手术时间、简化手术操作,它能使主刀医师在术前充分了解患者局部情况并制定合理手术方案,有助于手术的顺利实施。

3D-printed prostheses for large bone defect reconstruction following bone tumor surgery北大核心

BACKGROUND: Tumor segment resection is one of the standard methods for the treatment of bone tumors. However, the reconstruction of bone defects atumor resection faces many challenges. A growing number of researchers are focusing on 3D-printed prostheses for bone defect repair and reconstruction following bone tumor surgery. OBJECTIVE: To explore the feasibility of 3D-printed prostheses in the reconstruction of large bone defect following bone tumor surgery and to evaluate the postoperative outcomes. METHODS: Retrospective analysis of clinical data of 24 patients [19 males and 5 females, age 23.8 (6-61) years] who underwent bone tumor resection and 3D-printed prosthesis implantation in the Department of Bone Oncology, the First Affiliated Hospital of Xinjiang Medical University from December 2020 to September 2021 was conducted. There were 7 cases with distal femur tumor, 5 with pelvis tumor, 4 with proximal tibia tumor, 3 with middle femur tumor, 1 with distal tibia tumor, 1 with proximal humerus tumor, 1 with middle humerus tumor, 1 with scapula tumor, 1 with ulna tumor, and 22 cases with primary tumors (13 osteosarcoma, 4 Ewing sarcoma, 2 giant cell tumor of bone, 1 chondroblastoma, 1 chondrosarcoma, and 1 osteoblastoma), 2 metastatic carcinoma. Preoperative and postoperative imaging data were recorded and neoadjuvant chemotherapy was administered in 17 cases before surgery. The Musculoskeletal Tumour Society score was used to assess limb function before surgery and 6 months after surgery, and pain was assessed by the Visual Analog Scale, as well as the complications were recorded. RESULTS AND CONCLUSION: (1) All patients undergoing resection of the tumor segment and 3D-printed prosthesis implantation for the reconstruction of the bone defect were followed for 6-49 months, and the results showed that the length of osteotomy was (18.2 ± 7.3) cm and an average intraoperative bleeding volume was 740 (100-3 000) mL. (2) Two patients died of systemic metastasis, the remaining 22 had no pulmonary metastasis or recurrence during the follow-up period, and 1 patient developed aseptic loosening of the prosthesis at 25 months postoperatively. (3) The Musculoskeletal Tumour Society scores were significantly increased, while Visual Analog Scale scores were significantly decreased (P < 0.05) at 6 months postoperatively. (4) The Musculoskeletal Tumor Society score was rated excellent in all 22 patients at the final follow-up. (5) These results suggest that 3D-printed prosthesis is suitable for the reconstruction of large bone defects caused by bone tumor resection. Patients have good postoperative function and few complications. However, further investigations are needed to explore long-term follow-up results. © 2023, Publishing House of Chinese Journal of Tissue Engineering Research. All rights reserved.
