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.     

胞宫胞脉胞络理论与子宫内膜容受性关系探析

胞宫胞脉胞络理论是中医基于脏腑理论对女子生殖功能的基本认识.子宫体、宫颈、卵巢、输卵管、盆壁及其相关的血管、神经、韧带及受体当属胞宫、胞脉、胞络功能范畴.胞脉和胞络属于胞官的一部分.胞脉、胞络将脏腑化生之气血全面布散于胞官,心、肾通过胞脉、胞络与胞官相联系."精满" "血足"是良好子宫内膜环境的体现.肾气亏损,胞脉失疏,冲任不充,胞官瘀滞,藏泻失序,表现为子宫内膜较薄及血供不足,不利于孕卵的着床.治疗子宫内膜容受性低下应予补肾气,通胞脉,自拟二补助育汤,可以改善子宫内膜血液循环,增加子宫内膜厚度,提高辅助妊娠成功率.     

软组织损伤引起慢性疼痛的治疗

目的：综述运动系统软组织损伤引起慢性疼痛的各种治疗方法的研究进展。资料来源：应用计算机检索Medline1980—01／2006—04与运动系统软组织损伤引起慢性疼痛的治疗相关文章，检索词“Soft tissue injury，pain．chronic，comprehensive therapy”，并限定文章语言种类为“English”；同时计算机检索中国期刊全文数据库1994—01／2006-04期间的相关文章，检索词“软组织损伤、慢性疼痛、治疗方法”，并限定语言种类为中文。同时手工查阅相关书籍。资料选择：对资料进行初审，所选文献内容符合：①软组织损伤引起的慢性疼痛药物治疗的研究。②软组织损伤引起的慢性疼痛微创治疗的研究。③软组织损伤引起的慢性疼痛运动疗法的研究。④软组织损伤引起的慢性疼痛心理治疗的研究。⑤软组织损伤引起的慢性疼痛其他疗法的研究。排除重复性研究的文献。资料提炼：共收集到40篇关于软组织损伤引起的慢性疼痛治疗方法的文献，均为全文，23篇符合纳入标准，排除17篇重复性研究。同时录入书籍3本。资料综合：软组织损伤引起的慢性疼痛的产生是生理、心理及社会因素复杂结合的结果，个体表现差异较大，目前尚无特效治疗方法，常用的治疗方法有：药物治疗、微创治疗、运动疗法、心理治疗、物理疗法及其他疗法。结论：对于软组织损伤引起的慢性疼痛的治疗必须以整体的观点对其进行合理的评估和个体化治疗，才能收到良好的效果。

Pick’s disease with Pick bodies combined with progressive supranuclear palsy without tuft‐shaped astrocytes: A clinical,neuroradiologic and pathological study of an autopsied case

We report clinical, neuroradiologic features, and neuropathologic findings of a 76‐year‐old man with coexistent Pick’s disease and progressive supranuclear palsy. The patient presented with loss of recent memory, abnormal behavior and change in personality at the age of 60. The symptoms were progressive. Three years later, repetitive or compulsive behavior became prominent. About 9 years after onset, he had difficulty moving and became bed‐ridden because of a fracture of his left leg. His condition gradually deteriorated and he developed mutism and became vegetative. The patient died from pneumonia 16 years after the onset of symptoms. Serial MRI scans showed progressive cortex atrophy, especially in the bilateral frontal and temporal lobes. Macroscopic inspection showed severe atrophy of the whole brain, including cerebrum, brainstem and cerebellum. Microscopic observations showed extensive superficial spongiosis and severe neuronal loss with gliosis in the second and third cortical layers in the frontal, temporal and parietal cortex. There were Pick cells and argyrophilic Pick bodies, which were tau‐ and ubiquitin‐positive in neurons of layers II–III of the above‐mentioned cortex. Numerous argyrophilic Pick bodies were observed in the hippocampus, especially in the dentate fascia. In addition, moderate to severe loss of neurons was found with gliosis and a lot of Gallyas/tau‐positive globus neurofibrillary tangles in the caudate nucleus, globus pallidus, thalamus, substantia nigra, locus coeruleus and dentate nucleus. Numerous thorned‐astrocytes and coiled bodies but no‐tuft shaped astrocytes were noted in the basal ganglion, brainstem and cerebellar white matter. In conclusion, these histopathological features were compatible with classical Pick’s disease and coexistence with progressive supranuclear palsy without tuft‐shaped astrocytes.
