Objective: To assess the accuracy of multi-slice spiral CT (MSCT) with imaging reconstruction in judging bronchial involvement from central lung cancer. Methods: MSCT was done in 30 patients who were diagnosed as central lung cancer. Images of bronchi related to lobectomy or pneumonectomy were reconstructed by means of imaging processing techniques. Then the relation between tumor and bronchus was assessed prospectively with both axial CT and CT with imaging reconstruction in comparison with subsequent pathologic and surgical findings. Results: All 30 patients underwent thoracotomy, lobectomy or pneumonectomy. Total 66 bronchi were studied. Compared with axial CT images, CT with imaging reconstruction was better in judging the relation of bronchus and tumor in comparison with subsequent pathologic and surgical findings (0.01

Objective To make cephalometric analysis on the morphology of mandibular angle and its relationship with adjoining craniomaxillofacial structures in adults, and to discuss the application of the results in preoperative analysis and operation design. Methods Cephalometric analysis was made on the following parameters in 30 adults (15 men and 15 women) for frontal and lateral cephalometric radiograms: the distance between the mandibular angles (Go Go) and between the malar points (Zy Zy), and the mandible mental angels (Zy Go Me) on an anteroposterior cephalometric radiograph; the gonial angle (Ar Go Me), mandibular plane sella nasion angle (MP SN) and ramus plane sella nasion angle (RP SN). Results Go Go in male was (130?6) mm, female (116?6) mm; Zy Zy in male was (156?5) mm, female (146?5) mm; Zy Go Me in male was (117?5)?, female (119?5)?; Ar Go Me in male was (117?5)?, female (119?5)?; MP SN in male was (27?5)?, female (29?5)?; RP SN in male was (94?5)?, female (93?5)?. Conclusion The morphology of mandibular angle should be envisioned in three directions. The results of evaluation can be served as the reference of preoperative analysis and surgery design.

0. 05). No significant difference was found in maternal and neonatal complications between the ANCA( + ) and ANCA(－) subgroups in S-PE subjects. But those 4 cases who developed renal function insufficiency patients were ANCA( + ). Conclusions ANCA might be associated with renal diseases in preeclampsia women, and further studies is required to determine whether ANCA is involved with the pathogenesis of preeclampsia.

Objective To study the impact of viral infection on stress protein gene expression and investigate the possibility that heat shock proteins interact with viral components during viral assembly in the brain of suckling mice experimentally infected with Hantaan virus (HV). Methods New born mice less than 72 h of age were inoculated into brain with the 100 LD50 of Hantaan virus (strain 76 118). At the 8th day mice died from brain disease. Brains were prepared for tissue sections and extracts for the experiments. The Hantaan virus infection, HSP70 induction and their co localization in brain of infected suckling mice were demonstrated by immunohistochemical staining and laser scan co focal microscopic double labling. The possible intereaction between HV structural proteins and HSP70 was further analyzed by immunoprecipitation of infected tissue extracts with antibodies to either HSP70 or to viral nuclear capsule proteins HV NP by using SDS PAGE and Western blotting. Results HV infection induced an increased levels of HSP70 expression at the cytoplasma of neurons in the brain of suckling mice HV NP protein proved to be co localized with HSP70. Monoclonal antibody (mAb) to HSP70 could co immunoprecipitate the HV NP, and similarly mAb to HV NP could co immunoprecipitate HSP70 from virus infected tissue extracts, but not from mock infected tissue extracts. Antibody, which recognized one of these two proteins, did not cross react with the other. Thus, the association between HSP70 and HV NP appeared to be specific.Conclusions Hantavirus infection can directly induce HSP70 expression, leading to the formation of HV HSP 70 viral antigen peptide complex which plays some roles in the course of viral infection and replication.

Objective To assess left ventricular(LV) regional and global systolic function of patients with coronary artery disease using strain parameter of velocity vector imaging(VVI) technique in quiescent condition. Methods Thirty patients with coronary artery disease and 30 healthy volunteers were enrolled in this study. The two-dimensional gray scale images were obtained in apical 4-chamber view,apical 2-chamber view and long axis view of left ventricle, and three levels of the short axis views(mitral valve, papillary muscle and cardiac apex). The LV wall was divided according to 18 segment model and the longitudinal,radial and circumferential systolic strain (SL, SR, SC) of each segment were analyzed. The difference between the epicardial and endocardial strain measurement were defined as strain gradient and the average of each strain component as global systolic strain. The correlation between global systolic strain of each strain component and the LV ejection fraction(LVEF) were analysed. Results Group A (coronary stenostic degree≤70%) included 176 segments, compared with control group, LS and LS gradient (LSG) decreased significantly from control group( P ＜0.05), while there was no significant difference in CS, RS and CS gradient (CSG) ( P ＞ 0.05). Group B ( coronary stenostic degree＞ 70% ) included 132 segments, compared with control group, LS, CS and RS decreased significantly in group B ( P ＜ 0.05), while there was no significantly difference in LSG and CSG( P ＞0.05). There were also significant difference in LS, RS,CS and LSG between group A and B( P ＜0.05). Global systolic strain of each strain component shown significant correlation with LVEF (P ＜ 0.0001 ). And the global longitudinal systolic strain (GLS) correlated with LVEF most tightly. Conclusions Strain parameter of VVI technique could not only accurately analyze the LV systolic dysfunction but also reflect the stenostic degree of coronary artery. GLS could be a new index for LV systolic function assessment in patients with coronary artery disease.
