The favorable survival of patient with MSI has been suggested to be related to pronounced inflammatory infiltration; however,the reason for non-association of MSI with survival is unclear. Our aims were to investigate the associations of inflammatory infiltration and tumor necrosis (TIM) with microsatellite status and clinicopathological factors in colorectal cancer patients in whom MSI was not related to survival. METHODS: Three hundred and one colorectal adenocar-cinomas were evaluated for inflammatory infiltration and 300 for TN under light microscope. RESULTS: Low infiltration at invasive margin (X2=3.94, P= 0.047) and in whole tumor stroma (X2=3.89, P= 0.049) was associated with MSI, but TN was not (X2=0.10, P = 0.75). Low infiltration was related to advanced stage (X2 = 8.67, P= 0.03), poorer differentiation (X2=8.84, P= 0.03), DNA non-diploid (X2=10.04, P= 0.002), higher S-phase fraction (X2=11.30,P=0.004),positive p53 expression (X2=7.94,P=0.01),and worse survival (P = 0.03 for both univariate and multivariate analyses). Abundant TN was related to advanced stage (X2=17.74, P= 0.001) and worse survival (P= 0.02 for univariate, and P= 0.05 for multivariate analysis). CONCLUSION: The result that high inflammatory infiltration was not related to MSI might help explain the non-association of MSI with survival in colorectal cancer patients.展开更多

Methods：A total of 60 patients with 1 A-CP/CPPS suitable to operation and differentiated as Chinese medicine Gan（肝）-qi stagnancy syndrome type were selected.They were assigned with the random number table to two groups equally.Before operation,the patients in the treated group were administered with Proscar combined with AKM,but those in the control group treated with Proscar only.Suprapubic transvesical prostatectomy was performed two weeks later,and prostatic pathological examination was conducted.Results：Grading of inflammatory cell infiltration showed that the mean grade in the treated group was 0.78±0.90 grades,which was sihnificantly lower than that in the control group 1.68±0.87 grades（P〈0.05）.However,the two groups were not different in the grades of fibroblast proliferation（1.50±0.70 grades vs 1.62±0.87 grades,P〉0.05）.Conclusion： AKM could suppress the inflammatory cell infiltration,be an effective and safe remedy for the treatment ofⅢA-CP/ CPPS of Gan-qi stagnancy syndrome type,and worthy for spreading in clinical use.展开更多

On imaging, inflammatory demyelinating pseudotumor appears very similar to intramedullary tumors such as gliomas. It is often misdiagnosed as intramedullary tumor and surgically resected. In view of this, the clinical and magnetic resonance imaging manifestations and the pathological fea- tures of 36 cases of inflammatory demyelinating pseudotumer in the spinal cord were retrospec- tively analyzed and summarized. Most of these cases suffered from acute or subacute onset and exhibited a sensofimotor disorder. Among them, six cases were misdiagnosed as having intrame- dullary gliomas, and inflammatory demyelinating pseudotumor was only identified and pathologically confirmed after surgical resection. Lesions in the cervical and thoracic spinal cord were common. Magnetic resonance imaging revealed edema and space-occupying lesions to varying degrees at the cervical-thoracic junction, with a predominant feature of non-closed rosette-like reinforcement （open-loop sign）. Pathological examination showed perivascular cuffing of predominantly dense lymphocytes, and demyelination was observed in six of the misdiagnosed cases. These re- sults suggest that tumor-like inflammatory demyelinating disease in the spinal cord is a kind of special demyelinating disease that can be categorized as inflammatory pseudotumor. These solitary lesions are easily confused with intramedullary neoplasms. Patchy or non-closed reinforcement （open-ring sign） on magnetic resonance imaging is the predominant property of inflammatory de- myelinating pseudotumor, and inflammatory cell infiltration and demyelination are additional patho- logical properties.展开更多

Deregulation of VEGF signaling contributes to the physiopathology of many diseases. However, the ways in which infection with Paracoccidioides brasiliensis affects VEGF signaling and the influence of immunization with rPb27 （recombinant protein Pb27） on VEGF signaling have not yet been studied. Animals were immunized with rPb27 and subsequently infected with a virulent strain of P. brasiliensis. The fungal load was evaluated by measuring CFU （colony-forming unit） and histology was performed to evaluate the inflammatory reaction. At the two time points analyzed, the PC （positive control） and TREAT （treated） animals had decreased levels of pulmonary VEGF compared to basal levels. However, in the immunized （Pb27） and treated mice （Pb27 ＋ TREAT）, VEGF expression remained unchanged after infection. In the case of VEGFR-2, the Pb27 and Pb27 ＋ TREAT groups showed increased levels of expression. Regarding the levels of the eNOS enzyme, only the Pb27 group did not reduce the expression levels relative to baseline. The immunization with rPb27 kept VEGF signaling, NO production and increased VEGFR-2 expression, after infection with P. brasiliensis. Thus, the authors infer that immunization with rPb27 protects mice from the disruption of VEGF signaling in Paracoccidioides brasiliensis infection.展开更多
