Objective To introduce a method to repair soft tissue defect in different regions and different areas of hand in one procedure. Methods From May 2002 to May 2005, anterolateral femoral flap or lobulated anterolateral femoralflap(forming irregular anterolateral femoral flap) was designed into different shapes to repair multiple soft tissue defect in different regions in hand, whichwas used clinically in 27 cases. Among 27 cases, there were 16 males and 11 females; the locations were left hand in 9 , right hand in 16 and left foot in 2; including 5 penetrating injury, 9 hotpressing injury, 2 soft tissue defection of instep and planta by milled injury, 6 gearing injury and 5 carding machine injury. All the cases complicated by exposure of tendons, bones or joints. Defect was repaired with H-shape flaps in 5 cases of penetrating palm injuries; with Y-shape or K-shape flaps in 11 cases of dorsals or combined with fingers of hand with skin defect; with shape flaps in 3 cases of dorsals combined with sides of palms or the first web of hands with skin defect and in 2 cases of skin defects of dorsals combinedwith palms of feet;with h-shape flaps in 6 cases of skin defects of dorsal or palms combined with disconnected skin defect of fingers. The sizes of main flaps ranged from 6.5 cm×4.8 cm to 17.0 cm×12.0 cm, the sizes of lobulate flaps ranged from 3.5 cm×2.8 cm to 7.5 cm×4.5 cm. Results Allflaps survived without vascular crisis after operation. Except the fascia flapall recipient sites healed by first intention. The follow-up period ranged from 3 months to 1 year, all cases had satisfactory appearance, the texture of flaps was soft. Except 2 cases of penetrating injury, 3 cases of hotpressing injuryand1 case of carding machine injury whose function was not satisfactory, theremaining cases achieved the function of snap and pinch. More than 1 year after operation, the sense of pain and touch recovered. There was no functional impairment at the donor sites although scar hyperplasia was formed in some cases.Conclusion The application of irregular anterolateral femoralflap is an optimal choice for complex skin defect of hand.
目的探讨可吸收肋骨钉与记忆合金接骨板内固定两种方法治疗多发性肋骨骨折的效果。 方法回顾性分析2009年1月至2014年1月在上海市第六人民医院胸外科行手术内固定的胸部外伤致多根多处肋骨骨折患者321例的临床资料，其中可吸收肋骨钉组70例，其中男62例、女8例，年龄（48.54±9.74）岁；记忆合金接骨板组251例，其中男187例、女64例，年龄（51.44±10.22）岁。分析两组患者疗效差异。 结果两组患者术前疼痛评分（7.74±0.89 vs.7.66±0.92）、术后疼痛评分（3.80±0.79 vs.3.82±0.85），术后胸腔引流时间[（6.00±2.84）d vs.（5.68±2.98）d]差异均无统计学意义（P>0.05）。记忆合金接骨板组住院时间[（20.06±7.39）d vs.（17.77±7.68）d]，及手术时间（101.29±30.67）min vs.（71.95±29.50）min]均短于可吸收肋骨钉组，且差异有统计学意义（P＜0.05)。术后3个月随访复查胸部X线，两组患者骨折再移位差异无统计学意义。 结论可吸收肋骨钉与记忆合金接骨板均是治疗多发性肋骨骨折较理想的术式，记忆合金接骨板手术操作更为简单，可吸收肋骨钉手术无需在体内留置金属内固定装置，但固定强度较接骨板略差，应根据情况选择合适的内固定方法。
多发性硬化临床表现多样,其中大脑半球型多表现为精神症状、癫痫、偏瘫或感觉异常等,而以截瘫及排尿障碍为表现者少见。本文对表现为“脑性截瘫”的3 例MS患者的临床和MRI特点进行回顾分析,以此提高对于MS的认识水平。
目的 构建含小鼠血管内皮生长因子（mVEGF）的重组慢病毒表达载体，包装成病毒颗粒后感染NS-1小鼠骨髓瘤细胞株，以便进一步探索VEGF在骨髓瘤病理生理机制中的作用。 方法 聚合酶链反应法扩增mVEGF基因，克隆入含嘌呤霉素抗性的pCDH慢病毒表达载体，构建出表达mVEGF的慢病毒表达载体pCDH-mVEGF；采用磷酸钙法将慢病毒系统三质粒pCDH-mVEGF、psPAX2、pMD2.G共转染293FT细胞包装病毒，分别收集转染后48 h和72 h病毒上清并感染靶细胞NS-1，初次感染72 h后开始采用嘌呤霉素筛选稳定株，筛选2周后采用ELISA法检测稳定株细胞培养上清中mVEGF的表达，建立出稳定高表达mVEGF的NS-1小鼠骨髓瘤细胞株。 结果 成功构建重组慢病毒表达质粒pCDH-mVEGF，并包装成慢病毒颗粒，感染NS-1细胞株后获得靶基因的稳定高表达。 结论 成功构建出含mVEGF的慢病毒表达载体pCDH-mVEGF，慢病毒系统能有效介导目的基因在NS-1小鼠骨髓瘤细胞株中稳定表达，病毒包装成功并能有效感染NS-1细胞，为进一步探索VEGF在骨髓瘤病理生理机制中的作用奠定了基础。
The diagnostic frequency of multiple pulmonary tumor nodules has increased significantly in clinical practice. Among patients with multiple pulmonary nodules, distinguishing between separate primary lung carcinomas and intrapulmonary metastases is critical for accurate tumor staging, therapeutic decision-making, and prognostic evaluation. The consensus document "Differentiating separate primary lung adenocarcinomas from intrapulmonary metastases with emphasis on pathological and molecular considerations: Recommendations from the International Association for the Study of Lung Cancer Pathology Committee" highlights the pivotal role of integrated pathological and molecular analyses in diagnosing and differentiating primary lung adenocarcinomas from intrapulmonary metastatic lesions. It further proposes a combined four-step histologic and molecular classification algorithm for addressing multiple pulmonary tumor nodules of adenocarcinoma histology, providing clinicians with enhanced diagnostic tools to refine staging accuracy, guide therapeutic strategies, and improve prognostic predictions for lung adenocarcinoma. Building on current advancements in global research, this article offers a comprehensive interpretation of the consensus recommendations.
Objective To summarize the research progress of the treatment of primary hyperparathyroidism (PHPT) in multiple endocrine neoplasm type 1 (MEN1). Method The literature about the treatment of PHPT in MEN1 in recent years was reviewed. Results When the symptoms of MEN1 related PHPT were obvious, surgery was an effective treatment. In addition to conventional total parathyroidectomy with autotransplantation and subtotal parathyroidectomy, less-than subtotal parathyroidectomy, and single gland excision had also been proved to be effective recently. Conclusions Combining the clinical manifestations with the actual involvement of the parathyroid of MEN1 related PHPT patients, personalized selection of appropriate timing and methods of parathyroidectomy can help MEN1 related PHPT patients obtain ideal parathyroid function and ensure the quality of life to the greatest extent.
