[Expression and clinical significance of HIST1H2BH in head and neck squamous cell carcinoma].

PURPOSE: The purpose of this study was to investigate the expression of HIST1H2BH in head and neck squamous cell carcinoma (HNSCC) and to analyze its clinical significance. METHODS: The expression of HIST1H2BH in different tumors and HNSCC were analyzed based on the Oncomine and GEPIA database, and its relationship with clinicopathological parameters and prognostic value of HNSCC patients were also analyzed. The expression of HIST1H2BH in clinical specimens were detected by immunohistochemical staining. The variation of HIST1H2BH in HNSCC and its relationship with prognosis were analyzed based on the cBioPortal database. The interaction proteins and molecular mechanism of HIST1H2BH were preliminarily predicted using the String database. SPSS 24.0 software package was used for statistical analysis of the data. RESULTS: Analysis of Oncomine database and GEPIA database showed that HIST1H2BH was highly expressed in variety of tumors, and was significantly highly expressed in HNSCC. The expression level of HIST1H2BH was closely related to the pathological stage and prognosis of HNSCC patients, the prognosis of patients with high HIST1H2BH expression was poor. Immunohistochemical results of clinical specimens showed that the expression of HIST1H2BH in the cancerous tissue of HNSCC patients was significantly higher than that in the adjacent tissues. cBioPortal database analysis showed that the variation rate of HIST1H2BH in HNSCC patients was not high, but it was related to the disease-free survival rate. String database analysis showed that there were many genes associated with HIST1H2BH, and the signal pathways involved in biological processes were also complex. CONCLUSIONS: The expression of HIST1H2BH is elevated in HNSCC tissues, and its high expression is associated with poor prognosis. HIST1H2BH could be served as a marker for diagnosis and prognosis of HNSCC.

[Trigeminal herpes zoster with Ramsay Hunt syndrome: a report of one case and review of literature].

Trigeminal herpes zoster is a common disease in clinic. However, Ramsay Hunt syndrome with facial paralysis, earache and external auditory meatus herpes triad caused by herpes virus invading knee ganglion is rare. This paper reported a case of trigeminal herpes zoster complicated with Ramsay Hunt syndrome and reviewed the literature in order to further understand the nervous system infection caused by herpes zoster virus.
