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 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 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 ot lymph node metastasis and prognostic factors for carcinoma of papilla of Vater (CPV) after pancreaticoduodenectomy (PD).Methods From January 2005 to December 2010,94 patients with CPV underwent PD and dissection of regional lymph nodes at the Eastern Hepatobiliary Surgery Hospital.We carefully evaluated nodal involvement in the patients to determine the lymphatic spread of CPV and analyzed the clinicopathological variables in relation to prognosis.Results The overall rate of nodal involvement was 46.8%.Using the UICC staging (7th edition),lymphatic invasion in pT1,pT2,pT3 and pT4 were 15.4% (2/13),62.7% (32/51),80.0% (8/10) and 100% (2/2),respectively.The metastatic rates in the posterior pancreaticoduodenal lymph nodes,the mesopancreatic lymph nodes,the hepatoduodenal ligamental lymph nodes and the proper hepatic periarterial lymph nodes were 30.9% (29/94),21.3% (20/94),11.7%(11/94) and 6.4% (6/94),respectively.Significant prognostic factors were tumor pT stage (P<0.01),duodenal wall infiltration (P =0.001),liver metastasis (P =0.001),pancreatic paren chymal invasion (P=0.004),nodal involvement (P<0.01) and different regional lymph nodes invasion (the posterior pancreaticoduodenal,P<0.01; the mesopancreatic,P<0.01; the hepatoduodenal ligamental,P<0.01; the proper hepatic periarterial,P=0.010).Cox regression analysis for overall survival revealed that the posterior pancreaticoduodenal nodal involvement (P<0.01),the mesopancreatic nodal involvement (P<0.01) and duodenal wall infiltration (P=0.019) were significant independent prognostic risk factors.Conclusions The mesopancreatic lymph nodes and the posterior pancreaticoduodenal lymph nodes should equally be regarded as the first stop in lymphatic spread of CPV.Therefore,we should pay much attention to these regional lymph node dissections,especially to ensure complete resection of the uncinate process and the mesopancreas.

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.

Objective To study the developmental patterns and aging characteristics of anterior sacral foramina and posterior sacral forami-na in adolescents aging from 12 to 18 years old through CT imaging scanning and three-dimensional reconstruction measurement,and to provide the anatomical basis for the diagnosis and treatment of sacral vertebra diseases.Methods The 30 adolescents without any the problems of nerv-ous system were selected to conduct 64-slice spiral CT in the pelvic cavity.The original data were input into three-dimensional reconstruction software Mimics with the form of DICOM,and the relevant indicators were measured and analyzed.Results There was no significant difference in the height,width and distance of inner edge of anterior sacral foramina and the posterior sacral foramina in different gender and sides (P >0.05).The physical development of human increases gradually with age and there were significant differences.Conclusion There is a regular change process in the relevant indicators of anterior sacral foramina and posterior sacral foramina in adolescents.But the clinical appli-cation must be combined with the results of individual imaging,the technology of reverse engineering and the support of rapid prototype manu-facturing so as to meet the satisfactory results of individualized treatment.

Penetration enhancers are substances to improve the rate or amount of transdermal permeation which is an important factor in transdermal drug delivery systems (TDDS). Recent researches have found that some of the new penetration enhancers have a higher penetration-effect, little irritation, fewer adverse reactions, and stable properties. In this article, domestic and foreign research reports on penetration enhancers have been collected and summarized. The research progress of penetration enhancers were reviewed, with a purpose to provide a reference for reasonable selection of penetration enhancers.
