Objective:
To investigate the relationship between human cytomegalovirus (HCMV) infection and peripheral blood CD14 CD16 monocytes in the pathogenesis of coronary heart disease (CHD), and to elucidate the mechanism of pathogenesis in CHD by analyzing the correlation between infection, inflammation, and CHD, to provide a basis for the prevention, evaluation, and treatment of the disease.
Methods:
In total, 192 patients with CHD were divided into three groups: latent CHD, angina pectoris, and myocardial infarction. HCMV-IgM and -IgG antibodies were assessed using ELISA; CD14 CD16 monocytes were counted using a five-type automated hematology analyzer; mononuclear cells were assessed using fluorescence-activated cell sorting; and an automatic biochemical analyzer was used to measure the levels of triglyceride, cholesterol, high- and low-density lipoprotein cholesterols, lipoprotein, hs-CRp and Hcy.
Results:
The positive rates of HCMV-IgM and -IgG were significantly higher in the CHD groups than in the control group. HCMV infection affects lipid metabolism to promote immune and inflammatory responses.
Conclusion
HCMV infection has a specific correlation with the occurrence and development of CHD. The expression of CD14 CD16 mononuclear cells in the CHD group was increased accordingly and correlated with acute HCMV infection. Thus, HCMV antibody as well as peripheral blood CD14 CD16 mononuclear cells can be used to monitor the occurrence and development of CHD.

Group B coxsackieviruses (CVBs) are a group of common human pathogens producing various clinical symptoms. Although the virology of CVB is well known, there is limited information on viral pathogenesis and the relationship between clinical symptoms and viral phenotype, particularly for CVB type 2 (CVB2). In 2004 in Korea, two CVB2 strains were isolated: CB2/04/279 from stool of an acute myocarditis patient with heart failure and CB2/04/243 from an aseptic meningitis patient. In this study, a high degree of homology was observed between the CB2/04/279 and CB2/04/243 full genome sequences. The two Korean CVB2 isolates had 93.1% homology compared to 82.1%–82.5% nucleotide sequence identity with the cardiovirulence-associated reference CVB strain Ohio-1 (CVB/O). CVB2-induced pathogenesis was analyzed, focusing on virus-induced pathology of various tissues in 4-week-old BALB/c inbred male mice. Myocarditis developed and extensive pancreatic inflammation was observed in all mice infected with CB2/04/279 or CVB/O, but not in animals infected with CB2/04/243. This is the first report of the full-genomic sequence and pathogenesis of the CVB2 strain isolated from an acute myocarditis patient in Korea.

Tumor suppressor p53, known as 'the guardian of the genome', has the ability to prevent the emergence of transformed cells by the induction of cell cycle arrest and apoptosis. Otherwise, there were researches about the function of p53, such as NDA repair, regulating metabolism and maternal reproduction in recent years. Furthermore, there was a new function for p53 in antiviral apoptosis mentioned in the research, Integration of interferon-alpha/beta signaling to p53 responses in tumour suppression and antiviral defense. In order to define the antiviral function of p53, many target genes has been defined, such as IRF9, IRF5, ISG15 and TLR3. All of these implied there must be a complex mechanism for role of p53 in antiviral innate immunity, adaptive immunity and inflammation.

OBJECTIVETo investigate the effect of respiratory syncytial virus (RSV) infection on the production of thymic stromal lymphopoietin (TSLP) and Th1/Th2 balance in asthmatic mice.
METHODSThirty-two female BALB/c mice were randomly divided into 4 groups, namely the PBS group, ovalbumin (OVA) group, RSV group and OVA/RSV group. The mice were sensitized by OVA and then stimulated with nebulized OVA, and RSV was inoculated into the nasal cavity of the mice. BUXCO noninvasive lung function detection was performed to examine the airway response to metacholine, and enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of IL-4, IL-5, IL-13, and IFN-gamma in the mice. The cells in the bronchoalveolar lavage fluid (BALF) were counted and classified, and the supernatants of the BALF were used for the detection of TSLP. Histopathological changes in the lung tissues of the mice were examined using HE staining, and immunohistochemistry using anti-mouse TSLP antibody was performed to examine TSLP expressions in the airway epithelial cells.
RESULTSRSV infection promoted the production of TSLP in the asthmatic mice, and the concentration of TSLP in OVA/RSV group (2.13-/+0.05 ng/ml) was significantly higher than that in the other groups (P<0.01). RSV infection increased the serum levels of IL-4, IL-5, IL-13, and IFN-gamma in the mice. The total BALF cells, eosinophils, lymphocytes and neutrophils in OVA/RSV group were significantly higher than those in the other groups; noninvasive lung function examination showed higher Penh value in OVA/RSV group (318.66-/+50.87) than in the other groups when the inhaled metacholine increased to 6.25 mg/ml (P<0.01). More obvious and extensive airway inflammatory cell infiltration in OVA/RSV group were observed, and immunohistochemical staining also showed higher expression of TSLP in the airway epithelial cells of OVA/RSV group.
CONCLUSIONSRSV infection promotes the production of TSLP in the airway epithelial cells and increases the level of Th2 cytokines in asthmatic mice. Concurrent RSV infection can exacerbate Th2 inflammatory reaction in asthmatic mice.

OBJECTIVESTo understand the hepatic pathology, hepatitis B reactivation rates and serological changes in chronic HBV carriers.
METHODSA 5 year dynamic observation and survey of 220 chronic HBV carriers in Wuxi district was taken, analyzing their clinical symptoms, liver histopathology, virology and HBV immunological markers.
RESULTSThirty-five of the 220 (15.9%) patients, showed hepatitis B reactivation. The hepatitis B reactivation rate of patients with obvious hepatic tissue inflammation (> or = G2) was 27.0% (33/122) and the rate of the patients with mild hepatic tissue inflammation (G0-G1) was 2.0% (2/98), showing significant differences (x2=25.41, P less than 0.01). The reactivation rate of patients with high inflammation was clearly higher than those with mild inflammation. Twenty-seven of the 35 hepatitis B reactivation cases were older than 40 years, showing a significant association between the ages of the patients and hepatitis B reactivation rates (x2=6.72, P less than 0.01), moreover there was no relationship between sex and the hepatitis B reactivation rate. There were differences in the inflammation grades and fibrosis stages between HBeAg positive and anti-HBe positive group cases (Kruskal-Wallis Test, x2=8.68, P less than 0.01, x2=6.84, P less than 0.01), showing inflammation grades and fibrosis stages of the anti-HBe positive group were higher than those of the HBeAg positive group. There were no obvious differences about the inflammation grade between age less than 40 years old and > or = 40 years old group cases (x2=0.62, P more than 0.05), but there were significant statistical differences about the fibrosis stage (x2=7.37, P less than 0.01), showing fibrosis stage of more than 40 years old group cases was clearly higher than the less than 40 years old group cases. Fifty-six cases received a liver biopsy for a second time and 23 for a third time. We found those whose hepatic tissues were normal in their first liver biopsies, then their liver histology continued remaining stable for several years while those with abnormal ones hardly or only recovered slightly. The rate of HBsAg turning to negativity per year was 1.55% and for HBeAg was 5.4%.
CONCLUSIONThe hepatic tissue pathology for most chronic HBV carriers (55%) had significant abnormalities (inflammation grade > or = G2), and the rates of hepatitis B reactivation were highly relevant to the liver inflammation grades and the ages of the patients.

8.Effect of extracts from rabbit skin inflamed by vaccinia virus in the management of postherpetic neuralgia and on serum interleukin-6 level in aged patients.
Journal of Southern Medical University 2007;27(12):1941-1943
OBJECTIVETo observe the effect of the extracts from rabbit skin inflamed by vaccinia virus for injection, a commercially available agent (Analgecine), in the treatment of postherpetic neuralgia (PHN) in aged patients and its influence on serum interleukin-6 (IL-6) level.
METHODSA total of 44 elderly patients with PHN were randomly divided into two groups. In addition to the conventional antiviral therapy, patients in group A were given analgecine, and those in group B given indomethacin tablet. After the completion of the 14-day treatment course, the therapeutic effects were evaluated using visual analogue scale (VAS), and the changes in serum IL-6 levels after treatment were measured.
RESULTSThe score of VAS decreased significantly after treatment in group A (P<0.01), but not in group B (P>0.05). In both groups, the serum IL-6 level before treatment was significantly higher than that in normal control subjects (P<0.001), and lowered significantly after treatment (P<0.01) in group A, but not in group B (P>0.05).
CONCLUSIONThe extracts from rabbit skin inflamed by vaccinia virus have definite effects for rapid pain relief, and can effectively decrease the serum IL-6 level in elderly patients with PHN.
