Objective To find out the current thyroid volume of school children and its influencing factors in Chongqing.Methods Probability sampling method(PPS) was used to select 30 counties in Chongqing in 2011.Forty children aged 8-10of 1 randomly selected school from every county chosen were enrolled in the study.Thyroid volume of children was examined by B-ultrasonograghy.Body height and body weight were measured.The relationship between gender,age,height and weight and thyroid volume was analyzed,respectively.Results One thousand three hundred and twenty-two children aged 8-10 were investigated.The median of thyroid volume was 3.53 ml.The goiter rate was 5.52％ (73/1322).Thyroid volume of female and male was 3.55 and 3.51 ml,respectively.There was no significant difference of thyroid volume between female and male (H =0.68,P ＞ 0.05).Thyroid volume of children aged 8,9 and 10 was 3.30,3.53 and 3.76 ml,respectively.There was a significant difference of thyroid volume among different age groups(H =52.49,P ＜ 0.01).Thyroid volume of children height (110-,120-,130-and ≥140 cm,respectively) was 2.96,3.22,3.59 and 4.13 ml.There was a significant difference of thyroid volume among different height groups (H =149.23,P ＜ 0.01).Thyroid volume of children weight(17-,20-,30-and ≥40 kg,respectively) was 2.71,3.31,3.91 and 4.74 ml.There was a significant difference of thyroid volume among different weight groups(H =138.44,P ＜ 0.01).For the coefficients of simple and partial correlation,there was a significant correlation between thyroid volume and age,height and weight (P ＜ 0.05).The Spearman coefficient was 0.2411,0.3950 and 0.4285,respectively.The partial correlation coefficient was 0.0640,0.1154 and 0.2319,respectively.The standard partial coefficient of age,height and weight was 0.640,0.1154 and 0.3410,respectively.The proportion of the standard partial coefficients was 1 ∶ 1.8 ∶ 5.3.The function of body weight to thyroid volume was 5.3 times that of age and 3.0 times that of body height.Conclusions The goiter rate of schoolchildren in Chongqing is relatively high.Thyroid volume is affected by age,body height and body weight.The relationship between thyroid volume and iodine nutrition needs further study.

Objective To investigate the clinical effectiveness of coronary artery bypass grafting through descending thoracic aorta in elderly patients with coronary heast disease and to decrease the post-operative complication.Methods Thirteen elderly patients underwent coronary bypass surgery with minimally invasive direct coronary artery bypass (MIDCAB).Age range from 70 to 82 years with a mean of(72.1?6.0)years.Patients suffered from multi vessel disease.Many minimally invasive techniques of“Y”blood vessel graft anastomosis,anastomosis of blood vessel graft to descending aorta,minimally invasive direct,thoracoscope assist were used.Results All patients were survived.The mean duration of intubation was (6.9?0.9) hours.The average ICU stay was (2.5?0.5)days.No patients received blood transfusion.During the short-term follow-up(3 to 14 months) patients had no complaint of angina,Conclusions The technique of“Y”blood vessel graft anastomosis,descending aorta blood vessel graft,minimally invasive direct and thoracoscope assist in combination with coronary artery bypass grafting is a safe and cost-effective new procedure for elderly patients with multi-coronary artery disease.

Objective To explore the diagnosis and treatment of atypical extraventricular central neurocytoma. Methods We received 1 patient with atypical extraventricular central neurocytoma in January, 2010; the clinical and imaging manifestations, the pathologic features and microsurgical outcome were retrospectively analyzed; and the related literature was reviewed and compared. Results The lesions located at left frontal lobe, with clear boundaries to the brain tissue. Equal or slightly lower signals on MRI T1-weighted images (T1WI) and T2-weighted images (T2WI) was shown;inhomogeneous enhancement was noted on contrast-enhanced T1WI and T2WI. Meningioma was considered in the preoperative diagnosis. The tumor was grayish red and soft, and had general blood supply detected during the operation. Quick pathological diagnosis was made and it tended to be high-grade glioma. Immunohistochemistry indicated that the tumor cells were partly GFAP(+), S100(+)NeuN(+), Syn(+), Olig2(+), CgA(+), NSE(+) and NF(+), while those were EMA(-) and CD99(-); some P53 cells and about 10% Ki-67 cells were positive. These results prompted that these tumors having high proliferation index and atypical extraventricular neurocytoma was considered. Conclusion The imaging manifestation of EVN has certain features while immunohistochemistry is very important for its diagnosis. The best treatment is to perform microsurgery; the prognosis may be related to proliferation index of the tumor.

OBJECTIVETo analyze the molecular characteristics of the newly isolated two Japanese encephalitis virus strains (JEV) in Wuhan.

METHODSThe mosquitoes were collected in Wuhan from April to October in 2009. The envelope (E) protein gene of JEV was detected using RT-PCR and sequenced. Sequence comparisons and phylogenetic analysis were conducted using DNAstar and MegAlign.

RESULTSTwo Japanese encephalitis virus (JEV) strains (WHJX09-9, WHJX09-10) were isolated from Culex tritaeniorhynchus among 16 mosquito pools and identified as genotype I. The result showed that the homology of the two strains was 98. 9% in nucleotides and 100% in deduced amines. The comparison between the new genotype 1 JEV strains and live attenuated vaccine strain SA14-14-2 in E gene showed that the homology of nucleotide sequence was 87.4% and 87.9%, the homology of amino acid was 96.9% (total 15 amino acid were different) in E gene. The mutation sites of amino acid distributed among three different coding domain, but no antigen binding site and neurotoxin-involved site of amino acid were changed.

CONCLUSIONWuhan had appeared a new genotype of JEV which was different from the former strain isolated in Wuhan, the new JEV strains still had neurotoxicity but had high homology with the vaccine strains adopted in Wuhan. The vaccine could still be adopted to prevent Japanese encephalitis if steps were take to eradicate mosquitos at the same time. laboratory surveillance were also an important task to build an early-warning mechanism against JEV.

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.
