ABSTRACT
Objective@#To investigate the incidence of human rhinovirus (HRV) infection in hospitalized patients in emergency department.@*Methods@#A total of 94 emergency patients admitted to the emergency department from November to December of 2018 were enrolled in this study. The rhinovirus infection and related risk factors were analyzed.@*Results@#HRV infection occurred in 17 out of 94 hospitalized patients in emergency department, the infection rate was 18.09%; Multiple HRV serotypes were prevalent from November to December of 2018, which were A9, A10, A16, A31, A73, B42 and C3. Elderly patients are at high risk of rhinovirus infection; Rhinovirus infection may increase the course of inpatients.@*Conclusions@#From November to December of 2018, multiple serotypes of HRV infections in the emergency department of Bengbu, Anhui, and HRV easily infected elderly inpatients.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the expression of CD133 and CD44 in the primary gastric adenocarcinoma (GAC) and their relationship with the expression of E-cadherin.</p><p><b>METHODS</b>The expressions of CD133, CD44, and E-cadherin was examined by immunohistochemistry in 145 specimens of GAC tissues and 30 specimens of normal gastric tissues.</p><p><b>RESULTS</b>The positivity rates of CD133, CD44, and E-cadherin in normal gastric tissues were 10.0%, 0%, and 100%, respectively, showing significant differences from the rates in GAC tissues (46.9%, 47.6%, and 42.8%, respectively) (P<0.05). The expressions of CD133, CD44, and E-cadherin were significantly related with the tumor volume, differentiation, lymph node metastasis, invasive depth, pathologic-tumor-node-metastasis (pTNM) stages, and postoperative-survival time (all P<0.05); a positive correlation was found between the expression of CD133 and CD44, and they were both negatively correlated with E-cadherin expression (P<0.005). Kaplan-Meier analysis showed a significant difference in the survival rate between CD133-positive and CD133-negative patients (P<0.001) and between CD44-positive and CD44-negative patients; the patients with positive expression of E-cadherin had a significantly longer survival than those negative for E-cadherin. Cox regression analysis indicated that CD133, CD44, and E-cadherin expressions were all independent prognostic factors of GAC (all P<0.05).</p><p><b>CONCLUSION</b>The expressions of CD133, CD44, and E-cadherin are related to the tumor volume, differentiation, pTNM stages, invasive depth, lymph node metastasis, and prognosis of GAC, and their combined detection can be of important value in predicting the prognosis of GAC.</p>
