ObjectiveTo probe into the ultrasonic(US) predictive value for metastasis of the cervical lateral lymph node(LNM) with the preoperative ultrasonic examination in thyroid papillary microcarcinoma (PTMC),then,to further evaluate the significance of the preoperative ultrasonic score (US) for predicting metastasis of the cervical lateral lymph node.Methods From May 2004 to May 2011,165 patients diagnosed as PTMC (the ultrasonic imaging of lymph node showed no lateral LNM) were retrospectively analyzed and the US and final pathological data from the cases were collected to determine the relevant factors and different scores.ResultsThere were significant differences(P ＜ 0.05 )among US characteristics of microcalcification,no well-defined margin,tumor located at the upper pole,the perimeter of the tumor contacted with the adjacent capsule of thyroid being ＞25 ％ and the presence of the cervical lateral lymph nodes metastasis in PTMC between the metastatic group and the non-metastatic group.The total scores of the ultrasonic ≥2.5 was the delimitation value,its sensitivity was 86.2％ and its specificity was 89.7％.ConclusionsThe ultrasonic score has definite value in the differential diagnosis for the metastasis of the cervical lateral node in the patients of no lateral LNM,when the ultrasonic score is larger than 2.5,the possibility of the cervical lateral lymph node metastasis should be noticed.

With the modernization of traditional Chinese medicine (TCM), classic extraction methods such as sol-vent extraction, steam distillation, squeezing method, sublimation method have become much more difficult in sat-isfying needs of the development of the society as a result of low extraction rate of effective components, low per-centage impurity clearance. Therefore, in recent years the new extraction techniques with the advantages of green environmental protection , conditional stability , high extraction rate , strong biological activity , have been widely used in TCM extraction. These new extraction techniques have already shown each of its strength. The application progress on new extraction technology of Chinese medicine polysaccharide, both in standalone application and in collaboration application, were discussed in this article, so as to make new technologies be applied more reason-ably and effectively in Chinese medicine polysaccharide components.

Objective To investigate the efficacy and accuracy of quantitative computed tomography (QCT) in assessment of fracture healing. Methods Twenty-four healthy New Zealand rabbits were enrolled in the study and randomly divided into two groups, ie, Croup A (union model group, transverse fracture open created on mid-shaft of tibia and inter-fixed by kirschner wire) and Group B (non-union model group, transverse fracture with 5 mm defect on mid-shaft of tibia open created, then sealed with bone wax on fracture gap and medulla cavity, inter-fixed by kirschner wire). At 2, 4, 8 and 12 weeks, Kirschner wire was withdrawn and plain X-ray and QCT scanning were performed on the bilateral tibia. Then, rabbits were scarified and its bilateral tibia were desected and histologically examined. The result of X-ray and histological analysis was used as the "golden standard" for evaluation of fracture healing. Receiver operating characteristic curve (ROC) was used to analyze the evaluation performance of QCT. The corresponding segments of the contralateral healthy tibia were used as control to investigate the change of QCT parameters. Results In Group A, X-ray and histological analysis verified clear fracture line filled with irregular callus at 2 and 4 weeks but proved vague or vanishing fracture line and continuous and intact cortex of irregular callus at 8 and 16 weeks. In Group B, X-ray and histology analysis found clear fracture line with inactive ossification at 2 and 4 weeks but vague fracture line with scarce osteocyte and bone trabecula at 8 and 16 weeks. ROC analysis of QCT results showed the following results; (1) the areas under curve (accuracy) of material parameters including bone mineral density (BMD) and bone mineral content (BMC) were 0.781 and 0.750 respectively; (2) structure parameter-cross-sectional area (CSA) and the area under curve of cross-sectional moment of inertia (CSMI) were 0.781 and 0.469 respectively (P <0.05); (3) the areas under curve of the extending parameters bone strength indices (BSICSA) and CSMI bone strength indices ( BSICSMI) were 0. 913 and 0. 813 respectively (P < 0.05); (4) the area under curve (accuracy) of BSICSA, CSA and BMD were 0.905, 0.921 and 0.905 respectively (P<0.05). Conclusions QCT has potential in distinguishing fracture union and nonunion models in measurement of local fracture pattern. The screening parameters with more accuracy are BSICSA, CSA, BMD, which have advantages of accuracy and specialty in assessing fracture healing.

Objective To observe the sensitivity ofastrocytoma to chemotherapeutic drugs, in order to explore the drug selection using chemosensitivity testing in vitro on astrocytoma. Comparing different WHO grade astrocytoma to chemotherapeutic drugs sensitivity differences,providing the basis data for clinical treatment. Methods The astrocytoma cells were seperated and cultured in vitro from 142 tumor tissues by glioma resection, including 55 cases of low-grade astrocytoma (WHO grade Ⅰ , Ⅱ) and 87 cases of high-grade astrocytoma (WHO grade Ⅲ, Ⅳ). The proliferation inhibition and chemosensitivity of tumor cells to 11 drugs were investigated by using MTT method. Results There were 54.93% (78/142) patients recommended chemotherapeutic drug in 142 cases. The percentage was 41.82%(23/55) in the low-grade astrocytoma, and 63.22% (55/87) in the high-grade astrocytoma respectively. Teniposide,carboplatin,vincristine as the sensitive drugs were similar in different WHO grade astrocytoma. Conclusions The chemosensitivity testing could be used to filtrate sensitive drugs to clinical chemotherapy. The action is more prominent in high-grade astrocytoma than in low-grade astrocytoma. There is no difference in the choice of sensible drugs among different WHO grade astrocytoma.
