Objective To discuss the changes of correlative ultrasonic parameter index of normal hips and abnormal hips with developmental dislocation of the hip (DDH) in infants of different months in order to provide objective information for the diagnosis. Methods Three-hundred and seventy-eight normal hips and 244 hips with DDH among 622 hips of 311 infants were detected by ultrasonography(US). The morphology and structure information of hips were observed, and the values of ultrasonic parameter index,including angle α,angle 3, acetabular index( AI), femoral head percentage of cover(FHC) of normal hips and abnormal hips were measured. The values of each parameter index were collected by being divided into different groups (3 months a group) ,then the correlation was analyzed. Results Morphology and structure,position relation between femoral head and acetabulum of the hips were demonstrated by US. Normal or abnormal hips,the degrees of abnormal hips and the types of hips could be judged according to the findingsof US. Analysis of values of parameter index of normal hips:①There was significantly statistical significance in the values of ultrasonic parameter index, such as angle α, angle β, AI, FHC of normal hip between the groups of different age (P＜0.01). ②There was correlation between the age and the values of each parameter index, among which angle α, FHC had positive correlations with age ( r = 0. 537, 0. 554,respectively ) while angle β and Al negative correlations ( r = -0. 465, -0.424, respectively ). ③There was correlation between the values of different parameter index. Both angle β and AI had negative correlation with angle α,among which the latter correlation was closely ( r = - 0. 794). No statistical significance was found between the ultrasonic values of each group under different ages of different type abnormal hips( P ＞0.05) ,but closely negative correlations still existed between angle α and AI. ConclusionsUS can be viewed as an early definite and a screening method of diagnosing DDH.For older infants (above 6 months) it will be more accurate to analyze the ultrasonic parameter index together with the age of infants.

There are some shortcomings of animal experiments applied in chemical toxicity testing, such as long period, large cost, species differences and dose differences, which limit the use of animal experiments' results in predicting human toxicity.Accordingly, we established a toxicity testing alternative screening system in line with the toxicity endpoints which required in chemical safety evaluation and risk assessment (genotoxicity, carcinogenicity, reproductive toxicity, acute toxicity and general toxicity) based on 3R principles (replacement, reduction, refinement) for animal experiments.This system covers most of the endpoints of toxicity assessment, and molecular biology technology was also applied to integrate the toxicity test, as well as some operation was optimized in order to shorten the experimental period, reduce experimental costs, improve animal welfare.Furthermore, the results from the screening system have higher clinical relevance because it is based on the toxicity mechanisms.

Purpose To investigate the clinicopathologic features, diagnosis and differential diagnosis of ovarian juvenile granulosa cell tumor (JGCT).Methods The history records, pathologic features and immunophenotype of 8 cases of JGCT were retrospectively evaluated and their prognosis was achieved by follow-up.Results The age of patients ranged from 6～21 years old,with an average age of 15.1 years.The main clinical manifestations included an abdominal mass, ascites and isosexual pseudoprecocity. Cut surface of the tumor was typically solid with cysts formed. The histopathological changes displayed solid nests, diffuse sheet, multiple round or ovoid follicles in variable size.Macrofollicles could be seen in some cases.The follicular pattern consisted of small cystic cavities containing eosinophilic secretions. The tumor cells were round or polygonal, medium in size. The tumor cells had abundant pale or slightly eosinophilic cytoplasm, round nuclei with fine chromatin. Nuclear grooves were inconspicuous.Mitosis figures could be found. Immunohistochemical results showed that the tumor cells expressed inhibin-α,CD99,vimentin; while Melan-A,calretinin and S-100 were positive staining in part of the cases.CKpan,EMA,PLAP,Syn and CgA were negative in all the cases.Conclusions Ovarian juvenile granulosa cell tumor is a rather rare, low malignant tumor with good prognosis. Its diagnosis depends on the histologic and immunohistochemical findings and clinical features. Its differential diagnosis includes adult granulose cell tumor, hypercalcaemic type small cell carcinoma, carcinoid and dysgerminoma.
