Objective To study the relationship between cerebral vascular disease (CVD) and meteorological factors. Methods From 1998 to 2002, 6186 patients with CVD in Qingdao urban were studied. There were 1179 cases of intracerebral hemorrhage (CH), 4821cases of cerebral infarction (CI) and 186 cases of subarachnoid hemorrage (SAH). The relationship between the onset of CVD and meteorological factors including temperature, air pressure, relative humidity, wind velocity was analyzed by circular distribution analysis, Pearson correlation and multiple stepwise regression. Results High incidence of CH was found in winter and the mean angle was in January ((P

Objective To seek the specific receptors associated with hepatitis B virus (HBV) adhesion by separating the binding protein of the HBV preS1 region in HepG2 and performing the mass spectrometry .Methods The immunomagnetic bead method was adopted to separate HepG2 membrane protein combined with preS1 peptide fragment and the binding protein was separated by the sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) ,then the destination strips was analyzed by LC-MS/MS mass spectrometry and retrieved by the database .Results 16 bands were separated from HepG2 membrane proteins combined with preS1 by SDS-PAGE ;14 kinds of proteins were identified from 6 bands with better repeatability separated from HepG 2 membrane proteins combined with preS1 .Conclusion Protein analyzed by the mass spectrometry is mainly related with the material transport , cellular signal transduction ,antigen presentation ,immune regulation and energy metabolism .

Objective To analyze the characteristics, surgical timing and treatment of middle super thoracic fractures. Methods 35 cases of middle super thoracic fractures (T1 10) were retrospectively reviewed. Among them, 25 cases were complete injury of the spinal cord and 10 cases were neurologically incomplete injury. The bleeding in operations at different times, the ASIA grades and the sensorimotor scores were analyzed. Results The follow up showed that the ASIA grade increased by 1 to 2 degrees in 10 cases of incomplete spinal cord injury, while in complete spinal cord injury the ASIA grades hardly increased but the sense and motion scores could be improved by about 20. Conclusions Middle super thoracic fractures often involve multi vertebra body, and the spinal cord is injured severely. Decompression, fusion, internal fixation from posterior approach can obtain a satisfactory result. Neurologically incomplete injury should be treated as soon as possible, while complete injury of the spinal cord should be treated around 2 weeks after the injury.

Objective To study the multi-slice spiral CT (MSCT) manifestations of septic pulmonary embolism(SPE) in order to get a better understanding of the disease,Methods The MSCT manifestations of 12 patients with septic pulmonary embolism were retrospectively analyzed and compared with chest radiograph.Results Of the 12 patients,Chest radiograph and CT scanning showed multiple peripheral pulmonary nodules in 8 and 12 cases,a feeding vessel sigu(0,9 cases),cavitations(6,10 cases) and wedge-shaped opacities(4,7 cases),focal infiltrates(2,4 cases),air cyst(2,5 cases),pleural lesions (3,6 cases),hilar or mediastinal lymphadenopathy(0,3 cases).Peripheral or subpleural zones were most commonly affected (8,12 cases).CT was more useful in revealing nodules and a feeding vessel sign.Multiplanar reconstructions (MPR),maximum intensity projection (MIP) showed that most of these vessels passed around nodules and wedge-shaped lesions.MPR showed regular nodular margin.Conclusion SPE presents with variable and often nonspecific clinical and radiographic features.MPR and MIP showed the features of nodules and feeding vessels better.The diagnosis is usually suggested by the presence of a predisposing factor,febrile illness,and CT findings of multiple,periphery pulmonary nodules,with orwithout cavitation and a feeding vessel sign.

ObjectiveTo explore the clinical effect of video-assisted thoracoscopic surgery(VATS) for chronic empyema. Methods74 patients with chronic empyema were divided into experimental group and control group,control group was given decorticationoflung,and experimental group was given VATS. ResultsThe duration of chest tube drainage, hospitalization and complications in experimental group was significantly better than that in control group,it showed better clinical effect. ConclusionFor part of patients without the serious disease change of chronic empyema, if the surgery indication could be controlled strictly, the VATS was considerable.
