Fowl adenovirus serotype 4 (FAdV-4) strain SD1511 was isolated from chickens with severe inclusion body hepatitis and hydropericardium syndrome in Shandong Province, China. The isolate was cultured in primary chicken embryo kidney cells. A study of pathogenicity indicated that SD1511 readily infected 7-35-d-old chickens by intramuscular injection and intranasal and oral routes, causing 50%-100% mortality. The 35-d-old chickens suffered more severe infection than 7- and 21-d-old chickens with mortality highest in the intramuscular injection group. The serum from surviving chickens showed potent viral neutralizing capability. The complete genome of SD1511 was sequenced and analyzed. The strain was found to belong to the FAdV-4 cluster with more than 99% identity with the virulent FAdV-4 strains isolated in China in recent years except for some distinct variations, including deletions of open reading frame 27 (ORF27), ORF48, and part of ORF19. Our findings suggest that SD1511 might be used as a prototype strain for the study of pathogenesis and vaccine development.

OBJECTIVES: This study aimed to investigate how sleep quality affects quality of life in the elderly of rural communities. METHODS: 877 elderly people aged 60 or over living in C towns participated in the study. They responded to the Pittsburgh Sleep Quality Index, EuroQol-5 dimension, Korean version of the short from of Geriatric Depression Scale, Mini-Mental State Examination for Dementia Screening and the presence of urinary incontinence. RESULTS: Most scores of the items of the quality of life index, except self-management, showed significant correlations with the total score of the sleep quality test. Statistically significant differences were found between the positives and the negatives of the sleep quality test in the scores of all the detailed items of the quality of life index. Among the detailed items of quality of sleep, subjective quality of sleep showed the highest correlation. CONCLUSION: The present study found that the subjective indicators such as subjective sleep quality and sleep disturbance affected quality of life in the rural lives of elderly people more than the objective indicators such as sleep durations or sleep latency periods. Based on the results of these studies, we concluded that a methodological approach and a management model to treating insomnia to improve the quality of life of the elderly would need to be developed and applied.

Objective To investigate the methods and efficacy of microscopic surgical treatment in patients with anterior communicating artery aneurysm. Methods The clinical data of 35 patients with ruptured anterior communicating artery aneurysm, admitted to our hospital from January 2008 to January 2011 and performed microneurosurgical treatment via pterional approch, were retrospective analyzed; their surgical techniques and efficacy were concluded. Results All the aneurysms in 35 patients were successfully clipped. Follow-up was performed for 3-6 months: complete recovery was achieved in 19 patients, good recovery in 11, and mild disability in 3 (including 1 with psychiatric symptom); death appeared in 2 patients. Conclusion The microsurgery via pterional approach is an effective method in treating anterior communicating artery aneurysms,resulting from its full exposure of aneurysms and few complications; adequate dissection and exposure of the entire H shaped complex body of anterior communicating artery are the keys to a successful clipping of aneurysm neck; and the selection of aneurysm clip suitable for the aneurysm and the preservation of the perforating arteries should be specially emphasized.

OBJECTIVETo evaluate the relationship between the clinical stages of nasopharyngeal carcinoma (NPC) and Epstein-Barr virus (EBV) antibodies Rta/IgG, EBNA1/IgA, VCA/IgA and EA/IgA.

METHODSSerum samples obtained from 211 untreated patients with NPC categorized by the project of 92' stage were examined for the presence of the EBV antibodies Rta/IgG and EBNA1/IgA by enzyme-linked immnunosorbent assay (ELISA) and for VCA/IgA and EA/IgA by immunoenzymatic assay. The positive rates and antibody levels in the NPC patients in different TNM stages and clinical stages were analyzed statistically.

RESULTSNo significant difference in Rta/IgG rA value was found in the NPC patients in different TNM or clinical stages (P>0.05). The EBNA1/IgA rA value was significantly lower in stage T1, N0, and clinical stage I than in the other corresponding T stages, N stages and other clinical stage (P<0.05). The antibody titers of VCA/IgA and EA/IgA differed significantly between the N stages and the clinical stages (P<0.05).

CONCLUSIONThe expression of EBV Rta/IgG is not associated with NPC stage. The expression of EBNA1/IgA is relatively low in early NPC. The antibody level of VCA/IgA and EA/IgA are significantly correlated to the degree of neck lymph node metastasis, and might be helpful to classify the clinical stages of NPC.

Objective This study was aimed to investigate the clinical value of Epstein-Barr virus (EBV) Rta/IgG in the diagnosis of ansepharyngeal carcinoma (NPC). Methods Serum samples derived from 211 untreated patients with NPC, 413 subjects including 203 non-NPC ENT patients and 210 healthy volunteers as control were examined for the presence of antibodies directed against Rts/IgG by using enzyme-linked immnunosorbent assay (ELISA). Receiver operating characteristic (ROC) curve was applied to perform methodical evaluation of this tumor marker. Results The rA value median of Rta/IgG in NPC group was significantly higher than one in control group (P < 0.001). The area under ROC was 0.933. The sensitivity and specificity of this marker were 90.5% and 90.1%, respectively, when the best cutoff value was defined. Conclusion Rta/IgG detected with ELISA method is a new target of EBV, and may be one of important marker for NPC diagnosis.

BACKGROUND: To evaluate the prevalence and clinical characteristics of metabolic syndrome as defined by the NCEP-ATP III criteria in middle aged Korean rural people. METHODS: Cross-sectional study including 5330 participants (2197 males, 3133 females), over the age 40. Metabolic syndrome according to NCEP-ATP III criteria was defined if three or more of the following criteria were satisfied: 1) Abdominal obesity: Waist circumference (WC) in men > 102 cm and in women > 88 cm. 2) Hypertriglyceridemia: >or= 150 mg/dL. 3) Low HDL cholesterol: < 40 mg/ dL in men and < 50 mg/dL in women. 4) High blood pressure: >or= 130/85 mmHg. 5) High fasting glucose: >or= 110 mg/dL. We also applied WHO-APR (Asian Pacific Region) criteria for abdominal obesity (WC in men > 90 cm and in women > 80 cm) instead of NCEP-ATP III criteria. Insulin resistance was analysed by HOMA-IR. RESULTS: Age-adjusted overall prevalence of metabolic syndrome by NCEP-ATP III criteria was 24.8% (17.6% in men, 30.0% in women). The prevalence of metabolic syndrome for each age group in men was as follows: age 40 through 49 (18.8%), 50 through 59 (17.4%), 60 through 69 (18.3%), and over 70 (14.5%). In women: age 40 through 49 (22.3%), 50 through 59 (32.7%), 60 through 69 (39.9%), and over 70 (39.3%). In men, the prevalence decreased with aging, but not in women with consistent increment. Age-adjusted prevalence of abdominal obesity was 1.6% (men) and 25.3% (women) by NCEP-ATP III criteria, but 22.5% (men) and 55.6% (women) by WHO-APR criteria. Among various components of metabolic syndrome, the prevalence of hypertriglyceridemia was well correlated with the changing pattern of the prevalence of metabolic syndrome. Relative risk of metabolic syndrome increased as HOMA-IR and fasting insulin levels did. CONCLUSION: In middle aged Korean adults, metabolic syndrome defined as NCEP-ATP III criteria was strongly correlated to the degree of insulin resistance. The peak age of metabolic syndrome in men was age 40 through 49, and the prevalence decreased with aging. Therefore, early intervention for risk factors of metabolic syndrome might be required in men. On the other hand, prevention for cardiovascular disease will be needed for perimenopausal women due to considerably increased prevalence in the age 50 through 59.

BACKGROUND: The aim of this study was to analyze the prevalence and clinical characteristic of the metabolic syndrome of adults, over 40 years old, living in Korea. METHODS: This study was carried out for 2 years, 2003-2004, on total 5, 330 individuals (2, 197 men and 3, 133 women) selected by the stratified random cluster sampling among adults over 40 years old. Metabolic syndrome was defined based on both the NCEP-ATP III criteria and Modified ATP III criteria applying the WHO-APR (Asian Pacific Region) 's abdominal obesity criteria (waist circumference > 90 cm in men, 80 cm in women) instead of NCEP-ATP III criteria. RESULTS: Using NCEP-ATP III criteria, the age-adjusted overall prevalence of metabolic syndrome was 24.8% (17.6% in men, 30.0% in women). Age-adjusted overall prevalence of metabolic syndrome as defined by modified-ATP III criteria was 34.3% (26.3% in men, 40.1% in women). The prevalence of metabolic syndrome for each age group (40-49, 50-59, 60-69, > or= 70) in men was as follows: 18.8%, 17.4%, 18.3%, 14.5%. In women: 22.3%, 32.7%, 39.9%, 39.3%. The prevalence of hypertriglyceridemia (triglycerides > or= 1.7 mmol/l) was well correlated with the changing pattern of the prevalence of metabolic syndrome both in men and women. CONCLUSIONS: The peak age of metabolic syndrome in men was age 40 through 49, and the prevalence decreased with aging. Therefore, early intervention for risk factors of metabolic syndrome might be required in men. On the other hand, prevention for cardiovascular disease will be needed for perimenopausal women due to considerably increased prevalence in the age 50 through 59.
