Objective To develop a new mPCR method for rapid diagnosis of six types of encephalitis causing viruses of HS-VI,HSVII,VZV,EBV,EV71 and CMV.Methods Six pairs of specific primers for CMV,EV71,HSV I,VZV,EBV and HSV II were designed.The mPCR detection method was established and the sensitivity was detected.In order to verify the clinical application value of their multiplex PCR system,fifteen cerebrospinal fluid specimens of clinically suspected VE from the First Affiliated Hospital of Soochow University from 2014 to 2015 were examined by the mPCR method.Results The 6 pairs of primers did not interfere with each other,and the sensitivity of the mPCR system was over 103copies/μl.Among 15 cerebrospinal fluid specimens from patients with suspected viral encephalitis,six specimens(6/15,40%)were tested positive by the mPCR.Among them,HSV I was 5 and CMV was 1.Conclusion The mPCR method for detecting six types of en-cephalitis-associated virus at same time was established with high specificity,sensitivity and stability.

Many reports have been published on complications related to middle cerebral artery (MCA) aneurysm surgical clipping procedures. We report an emergency intracranial in situ bypass surgery case which was performed as a rescue procedure after aneurysmal neck laceration during clipping of an MCA large aneurysm. In this case, we performed in situ M3-superficial temporal artery (STA) interposition graft-M3 bypass procedure. If a STA-MCA anastomosis is not available under MCA flow obstruction, we can consider an emergency in situ MCA-MCA bypass procedure with or without an STA interposition graft.

PURPOSE: The favorable types of the breast cancer - medullary, mucinous, papillary and tubular carcinoma are uncommon subtypes and their incidences in different series ranges between 2.0% and 8.0%, 1% and 2%, 0.3% and 3%, less than 2% of all breast cancers, respectively. In westem countries these subtypes have been reported to have good prognosis and slow growth rate. Clinically, these tumors have lower frequency of axillary nodal involvement and better 5-year or 10-year surviral rate than the other common types of breast cancer. MATERIALS AND METHODS: To determine the clinical characteristics and to evaluate the correlation between the progrostic factors and survival rate of these tumors, the medical records of 83 women with medullary, mucinous, papillary and tubular carcinoma treated at Korea Cancer Center Hospital between Jan. 1987 and Dec. 1997 were reviewed retrospectively. RESULTS: The incidences of medullary, mucinous, papillary and tubular carcinoma were 0.51%, 1.45%, 0.71% and 0.14% of all breast cancer, respectively. There were 1 case of local recurrence and 5 cases of systemic relapse during the follow-up (median follow-up peroid of 56 months). Overall 5-year survival and 10-year survival rate were 98.5% and 94.2%, respectively. No significant difference in overall survival rate was detected according to histologic types of these tumors but disease-free survival was significantly lower in papillary carcinoma than the other types of these tumors (p=0.042). Standard prognostic factors of breast cancer such as tumor size, lymph node status, age of the patient and ER status did not affect the prognosis of these tumors. CONCLUSION: Medullary, mucinous, papillary and tubular carcinoma revealed very excellent prognosis in this study regardless of tumor size, lymph node status, age of the patients and ER status.

OBJECTIVETo evaluate the biological characteristics of Campylobacter jejuni (CJ) cultured on different culture media and their expression abundance of outer membrane proteins (OMPs).
METHODSCJ was cultured on the improved Bull's medium yolk agar, improved Bull's blood agar or improved Bull's agar for 48 h. The biological characteristics of the bacteria, including the colony feature, morphology, motility, biochemistry, and results of indirect fluorescence test were observed and compared. OMP of the cultured CJ was extracted using 0.2 mol/L and glycine-hydrochloride buffered solution (pH 2.2) and identified by SDS-PAGE to compare the expression abundance of the OMPs with molecular weight of 28-31 kD.
RESULTSCJ exhibited typical biological characteristics with larger cell body and more rapid growth on improved Bull's medium yolk agar than those on improved Bull's blood agar and improved Bull's agar. The bacteria grown on improved Bull's medium yolk agar showed also greater expression abundance of the OMPs with molecule mass between 28 kD and 31 kD.
CONCLUSIONImproved Bull's medium yolk agar allows rapid growth of CJ with typical biological characteristics and enhanced expression of the OMPs with molecular weight of 28 -31 kD, and can be widely used in CJ subunit vaccine development, CJ epidemiological survey, CJ food safety examination, and CJ quarantine.

Juvenile rheumatoid arthritis (JRA), an autoimmune disease, was characterized by chronic synovitis and associated with various extra-articular manifestations. Abnormal hematologic findings have been reported in all form of JRA, especially anemia due to chronic disease or iron deficiency. Dysplastic changes were rarely noted in the peripheral blood and bone marrow. We experienced a 15-year-old female patient with pauciarticular JRA who have pancytopenia in peripheral blood and a number of dysplastic changes in bone marrow, and present the case here with brief review of literatures.

Egg yolk immunoglobulin(IgY),also called egg yolk antibody,is a specific antibody secreted by birds after stimulation with certain antigens.For that it exhibits good resistance to heat,acid and proteinase-mediated degradation,its early-stage products were developed as food or food additives,and they have gained great social and economic benefits in both food safety and ecological agriculture fields.Due to the specific antibodies contained in these products,the products can help to resist pathogen infection.Therefore egg yolk antibody shows great value for development and application in the prevention and treat ment of animal and human diseases,and also shows great potential in human health care area.This review focuses on the development and applications of IgY biologics related with antiviral,antibacterial,antiparasitic and antitumor activities.

Although ascending aortic aneurysm is a uncommon disease, it has fatal complications such as aortic rupture, dissection, or death. So, experts recommend a preemptive aortic operation. A 77-year-old man with hypertension visited for slow progressive exertional dyspnea and general weakness. Chest X-ray showed deviation of trachea to right, mediastinal widening, cardiomegaly, and bulging of right heart border to right. Transthoracic echocardiography(TTE) and transesophageal echocardiography(TEE) showed marked dilated ascending aorta with wall calcification associated with severe aortic regurgitation and pericardial effusion. Measured diameter of ascending aorta was 12 x 11 cm on Chest Computed Tomography (CT) scan, 8.35 cm on TTE, and 10.2 cm on TEE. Our exam found out the obstructive pneumonia and aortic regurgitation as consequences of complications of huge aneurysm. We report a case of huge ascending aortic aneurysm without any previous aortic operation, aortic complications, trauma, or other etiologic factors.

OBJECTIVE: Post-craniotomy seizure (PCS) is reported only rarely. However, our department noted a 433% increase in PCS for a year beginning September 2010, especially after cerebrovascular surgery. Our goal was to identify the cause of our unusual outbreak of PCS. METHODS: For almost one year after September 2010, cases of PCS increased significantly in our department. We analyzed 973 patients who had received a major craniotomy between January 2009 and November 2011. We included seizures that occurred only in the first 24 postoperative hours, which we defined as early PCS. After verifying the presence of PCS, we analyzed multiple seizure-provoking factors and their relation to the duration and character of seizure activity. RESULTS: Overall PCS incidence was 7.2% (70/973). Cefazolin (2 g/L saline) was the antibiotic drug used for intraoperative irrigation in 88.4% of the operations, and no PCS occurred without intraoperative cefazolin irrigation. When analyzed by operation type, clipping surgery for unruptured aneurysms was the most frequently associated with PCS (80%). Using logistic regression, only 2 g cefazolin intraoperative irrigation (p=0.024) and unruptured aneurysm clipping surgery (p<0.001) were associated with early PCS. The seizure rate of unruptured aneurysm clipping surgery using 2 g cefazolin intraoperative irrigation was 32.9%. CONCLUSION: Intraoperative cefazolin irrigation must be avoided in patients undergoing craniotomy, especially for clipping of unruptured aneurysms, because of the increased risk of early PCS.
