RNA-binding protein CELF1 promotes tumor growth and alters gene expression in oral squamous cell carcinoma

The RNA binding protein CELF1 (also known as CUGBP1) is emerging as a critical regulator of cancer cell proliferation and apoptosis. Here, to provide a global prospective of CELF1 regulation of oral squamous cell carcinoma, we performed RNA-sequencing in oral cancer cells and CELF1 overexpression analysis in non-malignant human oral keratinocytes. Our approaches identified 1283 mRNAs differentially regulated as a function of CELF1 expression and more importantly CELF1 promoted alternative splicing of several target pre-mRNAs, which are known to be involved in various cancer biological processes. Overexpression of CELF1 in non-malignant human oral keratinocytes protected cells against oxidative damage and altered gene expression patterns. Finally, we provide evidence that reduction of CELF1 protein using a xenograft tumorigenesis mouse model decreased tumor growth. Altogether, these data provided a comprehensive view of the CELF1 mRNA regulatory network in oral cancer and suggests that CELF1 and/or its target mRNAs are viable candidates for therapeutic intervention.     

张仲景阳明腑实腹痛诊治理论对急性胰腺炎治疗的指导意义

张仲景对阳明腑实腹痛的诊治是系统的、有层次性的,按照腹痛的不同部位、不同性质及其不同的本证及兼证、变证,在通腑导滞的基础上治疗方药各有化裁。梳理阳明腑实腹痛诊治的层次性,讨论腹痛诊治理论的层次性对急性胰腺炎不同阶段、不同表现诊疗的指导意义,并提出"通腑导滞、中病即止"在重症急性胰腺炎治疗中的新观念,即通腑导滞不应仅局限于"得快利即止",而应涵盖于重症急性胰腺炎治疗全过程。     

Adult Renal Cell Carcinoma: A Review of Established Entities from Morphology to Molecular Genetics

According to the current World Health Organization (WHO), renal cell carcinomas (RCCs) that primarily affect adults are classified into 8 major subtypes. Additional emerging entities in renal neoplasia have also been recently recognized and these are discussed in further detail by Mehra et al (Emerging Entities in Renal Neoplasia, Surgical Pathology Clinics, 2015, Volume 8, Issue 4). In most cases, the diagnosis of a RCC subtype can be based on morphologic criteria, but in some circumstances the use of ancillary studies can aid in the diagnosis. This review discusses the morphologic, genetic, and molecular findings in RCCs previously recognized by the WHO, and provides clues to distinction from each other and some of the newer subtypes of RCC. As prognosis and therapeutic options vary for the different subtypes of RCC, accurate pathologic distinction is critical for patient care.

“Everything is so relaxed and personal” – The construction of helpful relationships in individual placement and support

The relationship with professionals is an important factor in relation to the outcome of interventions directed to persons with severe mental problems. However, the current knowledge regarding the development of helpful relationships within Individual Placement and Support (IPS) services is limited. The aim of the study was to investigate how participants in IPS services described their relationship with their IPS coach. The article is based on interviews from a Swedish government evaluation of IPS services, thematically analyzed. The results showed that the relationship with the coach is central for the participants’ success in the service. The main theme, “something different - as a human being” highlighted that the conditions for the relationship are different within IPS as compared to traditional services. The other themes were “here and now action,” “closer to wish-fulfilment – impact on the self,” and “from role to person.” The principles of IPS parallel the results from research about helpful relationships and offers good preconditions for the occurrence of such relationships. This can represent a bridge between evidence based methods and research on helpful relationships, and should be possible to implement in the development of evidence based methods as well as of treatment as usual.     

A novel role for drebrin in regulating progranulin bioactivity in bladder cancer

We recently established a critical role for the growth factor progranulin in bladder cancer insofar as progranulin promotes urothelial cancer cell motility and contributes, as an autocrine growth factor, to the transformed phenotype by modulating invasion and anchorage-independent growth. In addition, progranulin expression is upregulated in invasive bladder cancer tissues compared to normal controls. However, the molecular mechanisms of progranulin action in bladder cancer have not been fully elucidated. In this study, we searched for novel progranulin-interacting proteins using pull-down assays with recombinant progranulin and proteomics. We discovered that drebrin, an F-actin binding protein, bound progranulin in urothelial cancer cells. We characterized drebrin function in urothelial cancer cell lines and showed that drebrin is critical for progranulin-dependent activation of the Akt and MAPK pathways and modulates motility, invasion and anchorage-independent growth. In addition, drebrin regulates tumor formation in vivo and its expression is upregulated in bladder cancer tissues compared to normal tissue controls. Our data are translationally relevant as indicate that drebrin exerts an essential functional role in the regulation of progranulin action and may constitute a novel target for therapeutic intervention in bladder tumors. In addition, drebrin may serve as novel biomarker for bladder cancer.     

炙甘草汤加减在眼科疾病中的应用体会

目的观察中药炙甘草汤加减治疗眼科疾病的疗效。方法采用中药炙甘草汤加减治疗溢泪症、白塞氏综合征、视网膜分支静脉阻塞表现为阴阳失调、气血不足的患者,每日1剂,早晚分服。结果所有表现为阴阳失调、气血不足的患者都收到了较好的疗效。第1例,溢泪症的患者仅服5付中药溢泪症即完全消失,随访2年无复发;第2例白塞氏综合征的患者间断治疗2年,视力由治疗初的0.8恢复至1.0,病情稳定2年,后因劳累复发;第3例视网膜分支静脉阻塞的患者治疗70天,眼底出血及渗出完全吸收,视力由0.5恢复至1.0,随访1年病情稳定。结论炙甘草汤加减对阴阳失调、气血不足的眼科疾病有一定的疗效。
