Objective To investigate the value of MRI in evaluation of metastatic axillary lymph nodes in patients with breast carcinoma. Methods 60 patients with breast carcinoma underwent MRI before surgical management.Tumor maximal diameter,tumor SERmax (Maximal Signal Enhancement Ratio),the size,shape,border,signal intensity and enhancement pattern of ipsilateral axillary lymph nodes were recorded respectively.The results of MRI observation were compared with the histopathological results.Results Among the 60 patients,MRI showed that 28 cases had metastatic axillary lymph nodes,and 22 of them were confirmed by pathology.Its sensitivity,specificity and accuracy were 90.91%,78.95%,83.33% in the diagnosis of lymph nodes metastasis.Meanwhile,57 cases were underwent ultrasound examination,its sensitivity,specificity and accuracy were 59.09%,94.29%,80.70%.The sizes of lymph nodes in the patients with metastatic lymph nodes and the patients with no metastatic lymph nodes were(1.20±0.59)cm, (0.85±0.24)cm respectively.There was statistically significant difference between the two groups(t=3.258,P=0.001<0.05). There was statistically significant difference between the above two groups in the tumor maximum of SER(t=4.167,P=0.000<0.05),SERmax in metastatic lymph nodes were higher than in no metastatic ones.Irregular shape and border,inhomogeneous signal intensity and heterogeneous enhancement patterns were suggestive of metastatic lymph nodes.Conclusion MRI is an effective imaging modality in evaluation of axillary lymph nodes status in patients with breast carcinoma comprehensively before operation.

Objective:To explore the therapeutic effect of monoclonal anti EGFR antibody leading chemotherapy to human tumors.Methods:To prepare immunoconjugate of chemotherapy drugs with anti EGFR antibody and apply to clinic,and to observe it′s therapeutic effect and side effect. Results: This conjugated method could relief clinic symptoms and reduce side effect of tissues and organs significantly.Conclusion:Conjugates of monoclonal therapy of anti EGFR antibody and drug attached chemotherapy is a new and effective way for treatment of human tumors, and it can reduce side effect of the drugs meanwhile.

Objective To investigate the role of thrombelastography(TEG) in assessing the risk of bleeding and diagnostic value in patients with acute leukemia(AL) .Methods The TEG and PLT data were counted in 127 patients(272 sets of data) who were diagnosed with AL .Those patients were divided into two groups :group 1 (including patients with bleeding) and group 2 (in‐cluding patients with no bleeding) .The indicators(R values ,K values ,α‐angle ,MA values)and PLT count were compared between two groups .Those data with PLT<30 × 109/L of these two groups also were divided and the 4 indicators of TEG were compared between the two groups .We used the ROC curve to evaluate the sensitivity and specificity in assessing the risk of bleeding .Results According to the data in total ,the K value ,R value of the group 1 were higher than those of the group 2(P<0 .05);theα‐angle and MA value ,PLT counts of group 1 were lower than those of the group 2(P<0 .05) .In those AL patients whose PLT<30 × 109/L ,the K value of the group 1 was higher than that of the group 2(P<0 .05);theα‐Angle and MA value of the group 1 were lower than those of the group 2(P<0 .05);R values and PLT count were not different between the two groups(P>0 .05);the are‐as under the ROC curve about the PLT counts ,MA value andα‐angle were more than 0 .5 (0 .750 ,0 .740 and 0 .653) .Conclusion T EG could predict the risk of bleeding in acute leukemia patients and it could be used in clinical application .

Objective To investigate the risk factors for traumatic lumbar punctures in children with acute lymphoblastic leukaemia. Methods 132 children with acute lymphoblastic leukemia totally received 2634 lumbar punctures. The basic data on age, sex, body mass index (BMI), platelet count, interval between two punctures, and presence or absence of ultrasound-guided procedure were collected and analyzed. The risk factors for traumatic lumbar puncture were identified by logistic regression. Results The risk for traumatic lumbar puncture was higher in children younger than 1 year, and it was relatively lower in those aged 1 to 10 years. The risk for traumatic lumbar puncture was slightly higher in children with a BMI index of more than 95. The longer the interval between two punctures, the lower the risk. If lumbar puncture was guided under ultrasound or radiographic images, the risk was much smaller. Conclusions Age of younger than 1 year, BMI index of more than 95, shorter interval between two punctures, and direct puncture can increase the risk for traumatic lumbar puncture.

Objective The aim of this study was to investigate the feasibility and clinical value of detecting sentinel lymph node (SLN) with combined radioisotope and blue dye method in early stage cervical cancer. Methods Between March 2005 and April 2006, 50 patients with cervical cancer, who were staged Ⅰ b and Ⅱ a by International Federation of Gynecology and Obstetrics (FIGO), underwent SLN detection with preoperative lymphoscintigraphy. A dose of 148 MBq (4×10-4L) 99Tcm-sulfur colloid (SC) was injected into the uterine cervix at 3 and 9 o'clock position with lymphoscintigraphy taken at 15-60 min after injection. Intraoperative detection of "hot spot" lymph nodes was performed with a handheld gamma probe (γ-detection). During operation, 2-4 ml metend blue dye (BD-detection) was injected into the uterine cervix at the same positions. All patients underwent hysterectomy and pelvic lymphadenectomy. The spatial and pathological relationships of the SLN samples were compared between the two methods. SPSS 13.0 was used for statistical analysis. Results The detection rate of SLN with combined radioisotope and blue dye was 96.0% (48/50). γ-detection alone was 92.0% (46/50) and BD-detection alone was 70.0% (35/50, x2=4.92, P<0.05). In 37 patients lymphoseintigraphy showed the same SLN as γ-detection did, with a coincidence rate of 74.0% (37/50). The SLN with metastases were confirmed by histopathology in 11/48 (22.9%) patients. In the remaining 37 patients with SLN negative for metastasis, there was 1 case with non-SLN showing metastasis. In the 2 patients negative for SLN, 1 was positive for non-SLN metastasis. The SLN accuracy rate was therefore 97.9% (47/48), and the negative predictive value was 97.3% (36/37) with one patient false negative. About 72.3 % (115/159) of SLN were found in obturator region, 5.0% (8/ 159) in iuteriliac region, 12.0% (19/159) in external iliac chain, 6.9% (11/159) in common iliac region and 3.8% (6/159) in parametrium. The number of left-sided SLN detected was more than that of the right (x2=5.06, P=0.021 ). Conclusion Combined radioisotope and blue dye technique is a feasible and valuable tool to detect pelvic SLN in patients with early uterine cervical malignancy.

UNLABELLEDTo investigate the clinical and pathological characteristics, treatment, and The data of 12 patients prognosis of synchronous primary cancer of the endometrium and ovary. Methods with synchronous primary cancer of the endometrium and ovary were retrospectively reviewed . Results Eight patients had the same histological type of endometrioid carcinoma in both uterus and ovary, 4 patients had different histological types in uterus and ovary. Synchronous primary cancer of the endometrium and ovary was difficult to be dignosed preoperatively. All ovarian tumors were small with an average diameter of 7 cm. Infertility was common among these patients(40.7%). Most of them had early stage I lesion (66.7%). endometrioid carcinomas was the main pathologic type (66.7%). All patients were treated surgically followed by chemotherapy with a 3-year survival rate of 66.7% (8/12).

CONCLUSIONSynchronous primary endometrium and ovary cancer is a specific kind of tumor different from either the primary endometrium carcinoma or ovary carcinoma, and usually can be detected in early stage with a good prognosis.
