Objective To analyse the clinical and pathological features of cystadenocarcinoma in the intrahepatic biliary tract. Methods The clinical features of 14 patients with cystadenocarcinoma in intrahepatic biliary tract were analysed in respect to the results of ultrasonic and CT scannings, as well as pathological examination. Results Among the 14 patients, 11 were females and 3 were males. The age of the patients ranged from 32 to 79 years, and mean age was 59.5. The obvious symptoms were right-upper abdominal pain and abdominal distention, and major physical signs were hepatomegaly with cystic feeling. The ultra sonographic and CT scanning revealed cystic space occupying lesions in the liver. According to the invasion or infiltration of carcinoma to the liver tissue, the pathology of cystadenocarcinoma in intrahepatic biliary tract could be categorized into two types: the invading and non-invading. There were 8 patients belonging to the first type and they died 9～37 months after the diagnosis or operation, while 6 patients with no invasion were alive after operation. Conclusion The clinical picture and pathology of cystadenocarcinoma in intrahepatic biliary tract were described. The pathological classification was important in prognosticating the outcome of the patient.

Objective To establish an in vitro skin sensitization test,human cell line activation test (h-CLAT),based on THP-1 cell line (a human acute monocytic leukemia cell line),and to assess the sensitizing potency of plant raw materials of chemical and cosmetic products by this in vitro skin sensitization test.Method THP-1 cells were cultured in vitro and exposed to 11 reference skin sensitization chemicals and 9 samples,by monitoring the cell viability,cell surface marker CD54 /CD86 and relative fluorescence intensity of cells surface after the cells was exposures to the substances,and to discover whether there is a positive reaction.At the same time,Buehler test was used to validate the results of samples tested by h-CLAT.Results 11 reference chemicals were distinguished correctly by h-CLAT.Among the 9 samples tested,7 samples were recognized as negative sensitizer and 2 plant extracted substances were identified as suspicious skin sensitizer.The qualitative classification of the 9 samples by h-CLAT test was consistent with the results obtained by animal test.Conclusions The h-CLAT-in vitro test can be used to replace some animal tests for the prediction of soluble skin sensitizing substances.

Objective To investigate the changes of nuclear factor-κB (NF-κB),tumor necrosis factor-α(TNF-α),and cell apoptosis of cerebral ischemia-reperfusion injury and the influence of brain-derived neutrophic factor(BDNF) on these parameters in rats.Methods Eighty-four male Sprague-Dawley (SD) rats were randomly divided into two groups:BDNF (n =42) and control (n =42) groups.The BDNF group was induced using the improved Zea-longa method and were received abdominal injections of BDNF (0.5 μg/μl) immediately after injury.The control group was received abdominal injections with the same dose sodium chloride injection immediately after injury and repeated one time everyday until the rats was killed.Each group was divided into seven subgroups by sacrificed time after injury,including subgroups 1 h,3 h,6 h,12 h,24 h,3 d,and 7 d; each subgroup got 6 rats.Each subgroup were randomly selected three rats after being killed.The expressions of NF-κB and TNF-α of rats contusion peri tissues brain tissue were detected by immunohistochemical methods.Terminal deoxynucleotidyl transferase (TUNEL) method was used to observe the peri cell apoptosis after brain contusion.Results The expressions of NF-κB and TNF-α in BDNF group was significantly decreased relative to the control group (P ＜ 0.05),with a significant positive correlation between two parameters in two groups (P ＜ 0.001).The number of apoptotic cells was significantly decreased in the BDNF group relative to control group (P ＜ 0.05).Conclusions Brain-derived neutrophic factor probably relieves inflammation response,reduces the change of secondary brain injury after traumatic brain injury,and decreases neural cell apoptosis,and finally provides protection of neurocytes.

Objective To explore clinical significance of muhidetector(64-row)computed tomography carotid atherosclerosis angiography(MDCTA)in detecting carotid atherosclerotic plaque.Methods Data of 116 patients with carotid atherosclerosis undergone with MDCTA stayed at Huashan Hospital,Shanghai from January to August,2008 were analyzed retrospectively.Results Three hundred and seventy-seven plaques were identified among all the 116 patients in the study,with an incidence of calcified plaque of 63.40 percent,and more detected at the common carotid artery(27.85%).the carotid bifurcation(39.78%)and the internal carotid artery (21.48%).There was significantly statistical difference in plaque types between those with mild,moderate and severe carotid stenosis(P=0.000)and between those aged equal to or lower than 50 years and equal to or greater than 70 years(P=0.005).Plaque types at the common carotid artery were significantly difierent from those at the carotid bifurcation(P=0.000)and at the internal carotid artery(P=0.000).Results of regression analysis showed a positive and significant association between carotid occlusion and clinical symptomatology(with a coefficient of correlation of 1.080.P=0.023)and inverse association between calcified plaque and clinical symptomatology(with a coefficient of correlation of 0.688,P=0.006).Conclusions Not only imaging characteristics of carotid atherosclerotic plaque can be accurately assessed by MDCTA,but also measurement of its stenosis degree.Assessment of plaque type,degree of stenosis and distribution of plaque in different Vascular segments with MDCTA can be used to predict clinical occurrence of cerebevaseular events in patients with carotid atherosclerosis.

Background and purpose:Stromal tumor is one of the common gastrointestinal mesenchymal tumors. There is certain understanding about the typical cases. However, the diagnosis of those occurring in rare location or with rare imaging findings is often difficult. This research summarized this kind of cases,in order to increase the radiological knowledge of the disease.Methods:This study retrospectively analyzed clinical, radiological and pathological data from 550 patients who had stromal tumor conifrmed by pathology in our hospital. Those with incomplete data were eliminated. Forty-nine patients were selected for further study according to the typical imaging findings.Results:Among these 49 patients, 9 were pathologically confirmed to have extra-gastrointestinal stromal tumor, while 40 patients had gastrointestinal stromal tumor. Among the patients with gastrointestinal stromal tumor, 22 were found in rare locations, 12 in retroperitoneal space, 3 in omentum majus and mesenterium, 5 in esophagus, and 2 in prostate. Obvious cystic degeneration was found in 16 patients. Bulky calciifcation, such as lfake or annulus, was found in 7 patients. The analysis result of risk-stratiifcation showed 19 patients were conifrmed as high-grade among the patients with tumors found in rare locations, 15 as high grade among those with obvious cystic degeneration, and 7 as high-grade among those with extra-gastrointestinal stromal tumor.Conclusion:Rare stromal tumor often occurs in the locations, such as retroperitoneal space, omentum majus and mesenterium. Obvious cystic degeneration and bulky calciifcation can be seen. The risk-stratiifcation of these patients often showed high-grade. Comprehensively analyzing its clinical features and imaging ifndings can help improve the diagnostic accuracy.
