放疗同期卡莫氟化疗治疗局部中晚期鼻咽癌的Ⅲ期临床观察

目的:探讨患者对联合应用诱导化疗和放疗同期口服卡莫氟治疗局部中晚期鼻咽癌疗效和不良反应.方法:收治66例局部中晚期鼻咽癌患者,随机分为两组,诱导化疗随后放疗组简称为对照纽,诱导化疗随后放疗同期卡莫氟治疗组简称为治疗组.两组患者数均为33例.进行根治性放疗前两组患者均接受两个疗程诱导化疗.治疗组在放疗期间同时口服卡莫氟.结果:诱导化疗有效率高,平均有效率高达87%,其中平均完全缓解率(CR)为8.7%、不完全缓解率(PR)为78.4%.对照组鼻咽肿瘤、颈部转移淋巴结全消平均剂量均高于治疗组,统计学有差异.放疗后3个月治疗组鼻咽、颈部转移淋巴结CR均高于对照组(p=0.016,P=0.042).随访期内治疗组患者局部复发率和远处转移率有降低趋势.临床治疗中出现的主要毒副反应为白细胞下降、口腔粘膜炎、急性放射性皮炎及由卡莫氟引起的热感、尿频、头昏等.结论:放疗同期口服卡莫氟治疗局部中晚期鼻咽癌,降低了鼻咽和颈部肿瘤完全消退的照射剂量,提高了鼻咽肿瘤和颈部转移灶的完全缓解率,局部复发率和远处转移率有下降趋势.尽管加卡莫氟患者毒的副作用加重,但可以耐受,经对症处理绝大部分患者能按计划完成治疗.在鼻咽癌同步化放疗方案中卡莫氟的推荐剂量为600mg/d,分3次口服.放疗同期口服卡莫氟治疗的远期疗效有待于进一步观察.

肱骨中段骨折伴有桡神经损伤的手术探查

目的探讨肱骨中段骨折伴有桡神经损伤情况。方法对本院1998~2003年收治的164例肱骨干中段骨折病人进行回顾性研究,分析桡神经在各种骨折类型中的损伤及恢复情况,并应用SPSS11.0对结果进行分析。结果34.0%粉碎性骨折病人,25.0%螺旋型骨折病人,6.98%横行骨折病人出现桡神经损伤,术中探查见除3例粉碎性骨折出现桡神经部分损伤和横断伤之外,其他病人没有明显的桡神经损伤。13例急诊手术的完全性桡神经损伤病人虎口区感觉恢复时间平均为7.9周,肱桡肌和桡侧腕伸肌肌力恢复在伤后9周,完全恢复时间为3.4个月,12例非急诊手术的完全桡神经损伤的病人虎口感觉恢复在伤后9.8周,肱桡肌和桡侧腕伸肌肌力的恢复在伤后12周,完全恢复时间为4.5个月。结论高能量损伤、粉碎性肱骨中段骨折的病人桡神经损伤的可能性大,对于伴有桡神经损伤的肱骨中段骨折病人早期探查桡神经,神经恢复早,闭合复位要注意桡神经卡压损伤的可能。

Identification of the potential biomarkers for the metastasis of rectal adenocarcinoma

Rectal cancer is a common malignant tumor of the digestive tract, with a high incidence and high mortality. This study aimed to identify the potential biomarkers and therapeutic targets for rectal adenocarcinoma (RAC) metastasis. The expression profiling of RAC patients with metastasis and RAC patients without metastasis was downloaded from The Cancer Genome Atlas (TCGA) database. The datasets were used to identify the genes associated with RAC metastasis. Fifty up‐regulated genes and seventeen down‐regulated genes were identified in the primary tumor loci of RAC metastasis compared with non‐metastasis. Sixty‐seven dysregulated gens were conducted to construct the protein–protein network, and CCND3 was the hub protein. The dysregulated genes were significantly enriched in pancreatic secretion, cell adhesion molecules pathways, response to vitamin D of biological process, and retinoid binding of molecular function. Quantitative real‐time polymerase chain reaction results demonstrated that CCND3, AQP3, PEG10, and RAB27B had the up‐regulated tendency in RAC metastasis; ADCY1 had the down‐regulated tendency in RAC metastasis. CCND3, AQP3, PEG10, RAB27B, and ADCY1 might play essential roles in the metastasis process of RAC through pancreatic secretion and cell adhesion molecules pathways. The five genes could be potential diagnosis biomarkers or therapeutic targets for RAC metastasis.

Regulation of Toll-like receptor-mediated inflammatory response by microRNA-152-3p-mediated demethylation of MyD88 in systemic lupus erythematosus

Objective

microRNAs (miRNAs) play critical roles in embryogenesis, cell differentiation and the pathogenesis of several human diseases, including systemic lupus erythematosus (SLE). Toll-like receptors (TLRs) are also known to exert crucial functions in the immune response activation occurring in the pathogenesis of autoimmune diseases like SLE. Herein, the current study aimed to explore the potential role of miR-152-3p in TLR-mediated inflammatory response in SLE.

Methods

We determined the miR-152-3p expression profiles in CD4⁺ T cells and peripheral blood mononuclear cells (PBMCs) harvested from patients with SLE and healthy controls, and analyzed the correlation between miR-152-3p expression and clinicopathological parameters. CD70 and CD40L expression patterns in CD4⁺ T cells were assessed by RT-qPCR and flow cytometry. ChIP was adopted to determine the enrichment of DNA methyltransferase 1 (DNMT1) in the promoter region of myeloid differentiation factor 88 (MyD88).

Results

The obtained findings revealed that miR-152-3p was highly-expressed in CD4⁺ T cells and PBMCs of patients with SLE, and this high expression was associated with facial erythema, joint pain, double-stranded DNA, and IgG antibody. DNMT1 could be enriched in the MyD88 promoter, and miR-152-3p inhibited the methylation of MyD88 by targeting DNMT1. We also found that silencing miR-152-3p inhibited MyD88 expression not only to repress the autoreactivity of CD4⁺ T cells and but also to restrain their cellular inflammation, which were also validated in vivo.

Conclusion

Our study suggests that miR-152-3p promotes TLR-mediated inflammatory response in CD4⁺ T cells by regulating the DNMT1/MyD88 signaling pathway, which highlights novel anti-inflammatory target for SLE treatment.

     

“盾构术”的临床应用及潜在风险

上前牙拔除后唇侧牙槽骨迅速发生吸收,不仅降低上前牙区种植修复的美学效果,骨量不足也会影响种植体的长期成功率。近年来国内外报道“盾构术”在上前牙区应用实现了牙槽嵴轮廓的保持,成为一个新的美学区种植的治疗方案。但也有部分文献指出“盾构术”或其相关改良术式出现一些近远期并发症:如局部炎症、牙槽骨吸收、骨结合失败等。本文对“盾构术”相关文献进行综述,研究表明“盾构术”虽然在不少个案中获得良好的临床效果及短期成功率,但由于该技术缺乏长期及大量临床文献支持,在实际操作过程中存在许多不统一的意见,如牙片的厚度、牙片在牙槽骨内深度、牙片与植体间是否需要植骨等,操作具有技术敏感性,因此在临床应用中应谨慎采用该项技术,减少无法预料的风险。
