HUMAN herpes simplex virus esophagitis （HSVE） was first reported in 1940 by Johnson. ^1HSVE usually occurs in immunocompromised patients,such as those with acquired immunodeficiency syndrome （AIDS）, 2-4 malignancies, cutaneous burns, connective tissue diseases, inflammatory bowel disease, those taking immuno-suppressive therapy, and those undergoing organ transplantation,5 etc. In the immunocompetent individuals, HSVE is rare, having been reported in 39 cases and mainly affecting young males^6,7 The aim of this study was to delineate the clinical experience in the diagnosis of HSVE using rapid in situ hybridization and assess the various detection methods.

International guidelines for post-cardiac arrest care recommend using multi-modal strategies to avoid the withdrawal of life-sustaining therapy(WLST)in patients with the potential for neurological recovery.[1]However,a clear methodology for multi-modal approaches has yet to be ***-specific enolase(NSE)is currently the only recommended biomarker,and the European Resuscitation Council(ERC)and the European SocietyofIntensiveCareMedicine(ESICM)have proposed a cutoff value of 60μg/L at 48 and/or 72 h after the return of spontaneous circulation(ROSC)as a multimodal prognostic tool for predicting poor neurological outcomes.

Herein, we attempted to engineer oxygen vacancies on the surface of LaCoO_(3) perovskite through simple post-treatments(acid or reductive thermal treatments). Acid treatment induces oxygen vacancies through the selective etching of the La cations, whereas thermal treatment in a reducing atmosphere generates oxygen vacancies by directly removing lattice oxygen. The characterization results confirm that the number of surface oxygen vacancies, which are crucial in various catalytic oxidation reactions,considerably increases in the LaCoO_(3) catalysts treated with acid or reducing gas. Acid treatment enriches the oxygen vacancies while maintaining the structure of the LaCoO_(3) catalysts, which can not be achieved through reductive thermal treatment. Therefore, the acid treatment is considered a promising technique for oxygen vacancy engineering of perovskite catalysts for tuning their catalytic activities. Furthermore,the catalytic activities of the posttreated LaCoO_(3) catalysts for CO oxidation were evaluated and are noted to be considerably better than those of the pristine LaCoO_(3) catalyst due to their abundant oxygen vacancies. Consequently, we conclude that the oxygen vacancies of perovskite catalysts can be effectively engineered via two simple methods and play a significant role in CO oxidation.

Expression of oncogenes m colorectal cancer tissue was evaluated with immunohistochemical staining methods using monoclonal antibodies to products of the oncogenes. Rates of expression in colorectal cancer tissue were 52.5％ for c-myc, 67.0％ for c-erb B and 63.3％ for c-Ha-ras oncogenes. Expression of c-Ha-ras in colorectal cancer was not correlated with the histologic differentiation. However, expression of myc oncogene was higher in well differentiated adenocarcinoma(p＜0.05). There were no correlation between expression of c-Ha-ms, c-myc, and c-erb B2 oncogenes and lymph node and/or distant metastasis. Results showed that these three oncogenes were not related to the prognosis or survival of colorectal cancer patients.
