The prognostic role of tumour‐infiltrating lymphocytes in oral squamous cell carcinoma: A meta‐analysis

It has been suggested that tumour‐infiltrating lymphocytes (TILs) are associated with the progression of oral squamous cell carcinoma (OSCC). However, the prognostic value of TILs is inconclusive due to the heterogeneity of immune cells within the tumour microenvironment. In this meta‐analysis, we aimed to assess the prognostic value of TILs in OSCC. The PubMed, Cochrane, Embase, Scopus and Web of Science databases were searched up to April 20, 2019, and 33 studies were ultimately included in this meta‐analysis. Our pooled meta‐analysis showed that high infiltration of CD8⁺ TILs, CD45RO⁺ TILs and CD57⁺ TILs favoured better overall survival (OS). However, high infiltration of CD68⁺ macrophages and CD163⁺ macrophages was associated with poor prognosis in OSCC. These findings suggest that CD8⁺ TILs, CD45RO⁺ TILs, CD57⁺ TILs, CD68⁺ macrophages and CD163⁺ macrophages might serve as novel prognostic factors and therapeutic targets in OSCC.     

甘露醇在腰椎间盘突出症术后“反跳痛”治疗中的应用

目的：探讨甘露醇注射液在腰椎间盘突出症术后"反跳痛"治疗中的临床疗效。方法：收集2014年3月到2017年3月在我院行椎间盘镜下髓核摘除术的患者共82例，将所有患者随机分为3组，其中对照组27例，甘露醇组30例，地塞米松组25例。术前记录患者下肢痛的视觉模拟评分（VAS评分），腰椎日本骨科协会评估治疗分数（JOA评分）。术后甘露醇组使用20%甘露醇注射液125 mL静脉滴注，每8小时一次，连用一周。地塞米松组使用20 mg地塞米松磷酸钠注射液加入葡萄糖注射液，3 d后地塞米松减量为10 mg，连用一周。记录术后下肢痛的VAS评分和腰椎JOA评分，以及是否有下肢"反跳痛"及其VAS评分和持续时间。结果：3组患者手术前后VAS评分和JOA评分没有显著性差异（P>0.05）。3组患者术后下肢"反跳痛"的发生率没有显著性差异（P>0.05）。地塞米松可减少术后下肢痛的VAS评分，甘露醇无此效果，差异有显著性差异（P<0.05）。结论：甘露醇不能减少术后下肢"反跳痛"的发生率，疼痛程度和持续时间。     

Comparison of DNA fragmentation levels in spermatozoa with different sex chromosome complements

Research question

Do spermatozoa with different sex chromosome complements (X and Y; aneuploidy and monosomy) exhibit different degrees of DNA damage?

Tumor necrosis factor –238A is associated with pediatric‐onset generalized pustular psoriasis in Han patients in Eastern China

The correlation between polymorphisms at the tumor necrosis factor (TNF) gene and generalized pustular psoriasis (GPP) has rarely been reported. The goal of this study is to investigate whether TNF polymorphisms (?238 A/G, ?308 A/G, ?857C/T) are associated with susceptibility to GPP in a Han population from Eastern China and to perform subgroup analysis to explore the influence of age onset. Polymorphisms were assessed by polymerase chain reaction amplification and resequencing in 91 GPP patients and 102 healthy controls. The frequencies of the TNF ?238A allele and GA+AA genotypes were significantly higher in GPP patients than in those of healthy controls. The subgroup analysis revealed that these significant associations were still present between ?238A variants and pediatric‐onset GPP patients who developed GPP at less than 18 years old (PGPP), but not for patients with adult‐onset GPP who developed GPP at 18 years old or more. There were no significant differences in genotype or allele frequencies of TNF ?308 A/G and ?857C/T polymorphisms between GPP and controls. In conclusion, individuals carrying TNF ?238A may be more susceptible to PGPP.     

2015—2017年解放军总医院抗震颤麻痹药物的使用情况分析

目的 了解解放军总医院抗震颤麻痹药物的应用情况与用药趋势。方法 采用世界卫生组织（WHO）推荐的以限定日剂量（DDD）为指标的分析方法，对2015-2017年解放军总医院抗震颤麻痹药物的销售金额、用药频度（DDDs）、日均费用（DDC）及排序比（B/A）等进行统计分析。结果 普拉克索、多巴丝肼和恩他卡朋的用药金额始终处于前3位，普拉克索的用药金额逐渐上升，卡比多巴/左旋多巴的用药金额逐渐下降；DDDs排序列前2位的是多巴丝肼和司来吉兰，多巴丝肼的DDDs逐年上升，一直处于第1位；2015-2016年各种抗震颤麻痹药物的DDC较为稳定，2016-2017年各种抗震颤麻痹药物的DDC开始略有下降；除普拉克索和恩他卡朋的B/A始终小于1.00，其他抗震颤麻痹药物的B/A均在1.00以上波动。结论 解放军总医院抗震颤麻痹药物的使用较为合理，其中多巴丝肼、普拉克索和司来吉兰具有很好的市场前景。
