Lichen planus (LP) is a common oral disorder that may represent a mucosal reaction to a variety of factors, including hepatitis C virus (HCV). To determine whether viral factors play a role in oral lichen planus (OLP) pathogenesis, we measured serum HCV RNA and determined HCV genotype in patients with chronic hepatitis C accompanied by OLP. The subjects included 43 patients with chronic hepatitis C: 23 with OLP (group 1) and 20 without OLP (group 2). Serum was collected from all subjects and used to quantify HCV RNA by the branched DNA signal amplification assay; HCV genotypes were classified by the reverse transcription-polymerase chain reaction (RT-PCR) method into types I, II, III and IV. Comparison of patient characteristics disclosed that the mean age of group 1, 60.7 years, was significantly higher (P = 0.001) than that of group 2 (46.4 years). No significant differences were seen between sexes in values of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), total protein (T protein), albumin and gamma-globulin. There were also no significant differences in HCV RNA levels or HCV genotypes between groups. The findings suggested that OLP pathogenesis was a result of host factors rather than viral factors.

The current study was designed to determine the changes of the cardiac troponin I (cTnI) expression in blood and tissue during the myocardial degeneration in calves with foot-and-mouth disease (FMD). Seventeen crossbred calves presenting pathological signs for FMD confirmed by viral analysis were studied. A biochemistry panel and immunohistochemistry were performed on 17 diseased calves and 7 calves used as controls. Creatine kinase (CK), CK-myocardial band (CK-MB), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) activities were analyzed for both groups. Cardiac troponin I levels were measured by a commercially available enzyme-linked immunosorbent assay kit. Mean cTnI (14.8 +/- 1.9 ng/ml) concentration and CK (573 +/- 407 U/l), CK-MB (238 +/- 37 U/l), AST (84 +/- 7), and LDH (298 +/- 29 U/l) activities were higher in FMD cases compared with controls. Immunohistochemistry revealed loss or depletion of cTnI expression in myocardium of all cases. None of the 7 controls showed loss of cTnI expression. Increased serum cTnI concentration correlated with myocardial injury and loss of cTnI immunolabeling in cardiomyocytes of calves with FMD.

Hand-foot-mouth disease (HFMD) is a common pediatric disease responsible for the development of rashes or herpes on the hand, foot, and mouth. Severe complications of HFMD include myocarditis, pulmonary edema, aseptic meningoencephalitis, and even death. Therefore, early diagnosis of HFMD is of particular importance. In this study, we determined the clinical value of the combined detection of liver function and high-sensitivity C-reactive protein (hs-CRP) expression in children with HFMD. Three hundred children with HFMD were recruited to this study between July 2013 and July 2015 and divided into the mild and severe HFMD groups (N = 150 per group). The liver function [aspartate aminotransferase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP) levels] and hs-CRP expression were evaluated using standardized tests, and the clinical value of combined detection of these indices (in parallel and serially) was determined. Patients in the severe HFMD group showed significantly higher levels of ALT, AST, ALP, and hs-CRP compared to those in the mild HFMD group (P < 0.05). The hs-CRP and liver function tests had low specificity and sensitivity, respectively. However, parallel combined detection improved the sensitivity and negative predicted value of these indices, whereas serial combined detection improved the specificity and positive predicted value. In conclusion, hs-CRP and liver function play a major role in the diagnosis of HFMD (and identifying its severity), and serial combined detection of these indices enhances the positive predicted value, and could be employed to diagnose severe HFMD at an earlier stage.

Enterovirus 71 (EV-A71) and Coxsackievirus A16 (CV-A16) are the two most common pathogens causing hand, foot, and mouth disease (HFMD). Previously, we obtained one candidate live attenuated strain each for EV-A71 and CV-A16; here, we evaluated the safety and immunogenicity of a combinedlive vaccine against EV-A71 and CV-A16 generated from these two candidate strains. Rhesus monkeys were intramuscularly treated with a live combinationvaccine against both EV-A71 and CV-A16 or with either vaccine alone. No fever or atypical clinical signs were observed in any animals. Monkeys vaccinated with the combinationlive vaccine presented no notable pathological changes in the brain, spinal cord, lung, and liver; in contrast, these regions showed inflammatory cell infiltration in monkeys treated with EV-A71 alone or CV-A16 alone. Weak viremia was detected in plasma after inoculation with the combinationvaccine; however, the duration of viral shedding in feces was increased. Biochemical studies revealed a slight increase in aspartate aminotransferase levels in monkeys inoculated with the live combination vaccine; however, histopathological findings did not attribute this change to liver damage. We also found that the live combinationvaccine induced a dual humoral immune response. Cytokine analysis indicated that the combined EV-A71/CV-A16 vaccine significantly down-regulated interleukin-8 production. Here, we have demonstrated that the live attenuated EV-A71/CV-A16 vaccine was safe and could trigger a dual specific immune response. However, its immune protection efficacy requires further investigation.
