OBJECTIVESTo retrospectively review the results of closed reduction for developmental dysplasia of the hip (DDH), and analyze the causative for the unsatisfactory results of radiological.

METHODSFrom 1997 to 2005 the results of closed reduction for DDH in 60 children (77 hips) over 4.5 years period were retrospectively reviewed. Radiological final results of the patients were evaluated with Severin classification. The causative factors made from medical records and radiographs were used to make statistical analysis.

RESULTSSeventy-three percent of the patients (56/77) had satisfactory results according to Severin classification. Twenty-one hips classed as Severin III-V. Seventeen of the 21 hips had a reconstructive procedure. Avascular necrosis was observed in 29 hips (38%). The most important parameters affecting the result were age at reduction (P < 0.05) and avascular necrosis (P < 0.05).

CONCLUSIONSIn order to achieve better clinical and radiological results, the infants suffering from the DDH should be treated in the early stage. The postoperative avascular necrosis usually leads to poor prognosis.

Objective To investigate the danger of iodine excess for people in the downstream area of Yellow River in Shandong Province by describing the distribution of iodine excess water and the gorer of children Methods Water samples were collected from 5 villages of every town of Yuncheng,Jiaxiang and Dongchangfu Counties to determine the iodine of the water using arsenic cerium oxidation reduction method.In the 5 towns having water iodine in the range of 150～300μg/L,200 students aged from 8～10 years received the paJpation of thyroid,half of them were also measured of urinary iodine with As3+-Ce4+ catalytic spectrophotometry using ammonium persulfate digestion method,and 50 of the 100 students further underwent thyroid B-ultrasound.Results Three counties all have high iodine towns.The medium of urinary iodine of 30 town8 in 56 towns was higher than 150μg/L Urinary iodine and sign detection were performed in 13 towns,where water iodine was between 150～ 300μg/L;the medium ofurinary iodine of 11 towns were higherthan 400μg/L,and 3 of the 11 towns were higher than 800μg/L.In all 13 towns,the goiter rate of the students aged 8 to 10 years exceeded 5%by palpation in 11 towns:exceeded 5% by B-ultrasound method in 9 towns.Conclusions There are areas of iodine excess in drinking water and iodine-excess endemic goiter prevails in downstream area of the Yellow River in Shandong Province.It indicates that iodine excess in drinking water has done severe harm in these areas. Active management should be taken to control this endemic disease.

OBJECTIVETo study the validity and accuracy of differing cutoff scores of the Ages and Stages Questionnaires-Chinese (ASQ-C) for screening infants and toddlers in comparison with the gold standard, Bayley Scale of Infant Development, Second Edition (BSID II).

METHODThe 269 samples were enrolled from the normative children, aged 3 - 31 months, of the ASQ-C in Shanghai. The age-appropriate ASQ-Cs were completed by parents/caregivers and the BSIDIIwas administered by professionals. The cutoff scores of -2 standard deviation (s), -1.5 s, and -s for the ASQ-C were examined against BSID II with the cutoff scores set at -2 s as the standard of developmental delay, -s as the standard of suspected developmental delay and developmental delay respectively. Agreement between the classifications of the ASQ-C (i.e., typical, suspected, delay) was compared with the classification of the BSID II (typical, suspected, delay), sensitivity, specificity, Youden Index and area under ROC curve of ASQ-C were examined. The statistical analysis was carried out using SPSS 13.0.

RESULTWhen the cutoff score for BSID II was -2 s, the -2 s cutoff score for ASQ-C exhibited the following properties: the highest agreement of 83.64%, the sensitivity and specificity both above 80% being respectively 88.46% and 83.13%, the highest Youden Index of 0.72 and the largest area of 0.86 under ROC curve. The -1.5 s cutoff score for ASQ-C showed the following properties: 71.75% agreement, 100% sensitivity, 68.72% specificity, Youden Index = 0.69, the area under ROC curve = 0.84. The -s cutoff score for ASQ-C showed the following properties: the lowest agreement of 55.02%, 100% sensitivity, the lowest specificity of 50.21%, the lowest Youden Index of 0.50, and the smallest area of 0.75 under ROC curve. When the cutoff score for BSID II was set at -s, the -2 s for ASQ-C showed the following properties: the highest agreement of 85.87%, the lowest sensitivity of 68.57%, the highest specificity of 91.96%, Youden Index = 0.61, the smallest area = 0.77 under ROC curve. The -1.5 s for ASQ-C showed the following properties: the agreement of 80.67%, the sensitivity and specificity both above 70% being respectively 85.71% and 78.89%, the highest Youden Index of 0.65, the largest area of 0.82 under ROC. The -s cutoff score for ASQ-C showed the following properties: the lowest agreement of 68.40%, the highest sensitivity of 94.29%, the lowest specificity of 59.30%, the lowest Youden Index of 0.54, and the area under ROC curve = 0.80. When the cutoff score for BSID II was -1 to 2 s, the identifying percentages of the -2 s, -1.5 s and -s for the ASQ-C were 56.82%, 77.27% and 90.91%, respectively.

CONCLUSIONFor developmental delay identification, the -2 s cutoff score for ASQ-C produces the most robust validity and highest accuracy; for the identification of suspected developmental delay and developmental delay, the -1.5 s cutoff score for ASQ-C has the highest screening accuracy with appropriate sensitivity and specificity; for identifying the suspected developmental delay, the -s cutoff score for ASQ-C has the highest percentage of the identification. It is necessary to add 1 - 2 s to the ASQ-C's cutoff scores as the standard for screening suspected developmental delays.

Objective To investigate the present status of Kaschin-Beck disease(KBD) in Qingzhou at present, and provide a scientific basis for decision-making in controlling the disease. Methods According to The National Technical Scheme for Endemic Disease Control in 2007, children aged 7 to 12 were chosen to receive clinical and X-ray examination in 3 villages of 2 towns in Qingzhou. Local adults aged 16 years and older were clinically diagnosed in 10 villages of 4 towns and divided into different groups according to the clinical degrees and their ages. The Diagnostic Criteria of Kashin Beck Disease(GB 16003-1995) was carded out by clinical and X-ray diagnosis. Results Two hundred and sixty school children aged 7 to 12 were clinically diagnosed, and the patients of I degree upwards of KBD were not detected. One hundred and ninety-eight school children aged 7 to 12 were examined by X-ray, and the detectable rate was 0(0/198). In 7099 adults aged 16 years old upwards clinically tested, 502 patients of degree I and higher of KBD were detected and the detectable rate was 7.07%(502/7099). The patients distributed mainly in the population aged 36 years old and older, accounting for 99.00% (497/502). Conclusions Although KBD in children have been controlled in Qingzhou, it is still serious in adults. So the monitoring of KBD should be carried on and prevention and control for KBD in adults should be strengthened.

AIM: To establish an animal model of experimental autoimmune myocarditis (EAM) in BALB/c mice and to investigate the expression and significance of Toll-like receptor 3 in mouse EAM. METHODS: BALB/c mice were immunized with cardiac myosin extracted from porcine ventricular myocardium covered by complete freund's adjuvant (CFA) on 0 d and 7 d, then divided into immunized with CFA only. Serum and myocardium samples were collected at 14 d and 21 d after the first immunization. HE staining was used to identify the areas of inflammation. The myosin IgG antibody was examined by indirect ELISA assay. The changes of TLR3 protein and mRNA expression in myocardial tissue were measured by immunohistochemistry and real time-PCR. RESULTS: Compared to control group, immunohistochemistry results showed that there was positive expression of TLR3 in the myocardium of mice with EAM and the mRNA of TLR3 were more than 20 times (P<0.05). The expression of interferon beta mRNA in EAM group was more than 14 times as many as basal expression, that of tumor necrosis factor alpha was more than 18 times (P<0.05). CONCLUSION: The expression of Toll-like receptor 3 in myocardium is up-regulated in experimental autoimmune myocarditis. The inflammatory response to cardiac myosin may associate with the TLR3 signal transduction pathway.
