改良大骨瓣联合软通道微创介入逐渐减压术治疗重型颅脑损伤的疗效分析

目的：探讨改良大骨瓣联合软通道微创介入逐渐减压术治疗重型颅脑损伤的疗效。方法方便选择自2009年12月—2014年11月该院收治的重型颅脑损伤病例70例,随机分为改良组和对照组2组,每组35例,改良组施行改良大骨瓣联合软通道微创介入逐渐减压术,对照组按标准大骨瓣开颅、硬脑膜一次性全切开,对比分析两组的并发症发生率及预后。结果改良组发生迟发性颅内血肿、大面积脑梗塞及弥漫性脑肿胀等并发症9例(25.7％,9/35),预后良好者23例(65.7％,23/35),对照组发生并发症19例(54.3％,19/35),预后良好者14例(40.0％,14/35),两组并发症发生率和预后差异具有统计学意义(P<0.05)。结论改良大骨瓣联合软通道微创介入逐渐减压术治疗重型颅脑损伤,效果良好,显著降低死亡率。     

A Review of Primary Thyroid Lymphoma: Molecular Factors,Diagnosis and Management

Purpose/aim: To focus on current aspects of primary thyroid lymphoma (PTL), which is a rare clinical entity usually manifested by a rapidly growing mass in the neck that can cause pressure symptoms.

Materials and Methods: Relevant papers in PubMed published through June 2017 were selected to track updated information about PTL with an emphasis on diagnosis and novel therapeutic management.

Results: The most frequent cases include non-Hodgkin lymphoma derived from B-cells, mainly diffuse large B-cell lymphoma (DLBCL) followed by mucosa-associated lymphoid tissue (MALT) lymphoma or a mixed type. Other subtypes are less common. Lymphomas derived from T-cells and Hodgkin lymphomas are extremely rare. Hashimoto's autoimmune thyroiditis has been implicated as a risk factor for lymphoma. At the molecular level, the Wnt5a protein and its receptor Ror2 are involved in the course of the disease. Ultrasonography, fine needle aspiration (FNA) biopsy, and core or open biopsy combined with new diagnostic facilities contribute to an accurate diagnosis. An increased potential exists for a cure without the need for a radical surgical procedure. Modern chemoradiation therapy plus the monoclonal antibody rituximab, which acts against CD20, have limited the need for surgical interventions and provide an excellent outcome in most cases. However, some cases have resulted in treatment failure or recurrence.

Conclusions: A multidisciplinary approach must be used to define the management policy in each case. Future efforts by researchers are likely to be focused on the molecular level.     

早期联用MEP和大剂量rhGH对严重烫伤大鼠肠源性感染的影响

目的探讨早期联用美罗培南(MEP)和大剂量重组人生长激素(rhGH)对严重烫伤免疫抑制大鼠肠源性感染的影响。方法Wistar大鼠54只随机分为对照组、烧伤组和治疗组(C1组、C2组、C3组),后两大组制成25%总体表面积(TBSA)Ⅲ°烫伤免疫抑制模型,伤后2h给予rhGH1.33IU/kg、MEP20mg/kg,伤后8、24h检测门静脉血清内毒素(LPS)、腔静脉血清肿瘤坏死因子-α(TNF-α)含量,肝功能变化和肠道细菌移位率。结果C3(MEP+rhGH治疗)组LPS和TNF-α含量均显著低于其他组(P<0.01),与对照组差异无统计学意义(P>0.05),C3组未发现肠道细菌移位且肝功能检测指标显著低于其他组(P<0.01),与对照组差异无统计学意义(P>0.05)。结论早期联用MEP和rhGH治疗严重烫伤免疫抑制大鼠能显著减轻或防止肠道细菌/内毒素移位,减少炎症介质释放,保护脏器功能。
