Objective To study the presence of simian virus-40(SV40)DNA in tissue sections of malignant mesothelioma and to evaluate the relation of prognosis. Methods We reviewed 60 cases of malignant mesothelioma confirmed by the methods of histology,immunohistochemistry and electron microscopy.The polymerase chain reaction was applied to detect the presence of SV40 DNA in tissue sections of malignant mesothelioma.Results SV40 DNA was detected in the tissue of malignant mesothelioma(60%).We al…
Malignant pleural mesothelioma(MPM),originated from pleural mesothelium cell,is a fatal tumor with atypical manifestation and poor clinical outcome.Here we present a review of the manifestations of MPM by several imaging methods(X-ray,CT,MRI and PET/CT),with a discussion in the values of thoses methods in the diagnosis,staging and prognosis of pleural mesothelioma.
To study the pathological diagnosis,differential diagnosis and prognosis of lymphohistiocytoid mesothelioma(LHM).Methods Histopathological characteristics and immunohistochemical findings were studied in two cases of LHM with review of the literatures.Results Paients presented with chest pain in two cases.The tumors showed a diffuse proliferation of large,atypical fibrohistiocytoid cells intermixed with numerous lymphocytes,plasma cells and occasional eosinophils.Ultrastructurally,the cases …
To investigate the diagnosis and treatment of malignant pleural mesothelioma(MPM).Methods The clinical data of 18 cases with MPM covering a period frome 1999 to 2006 were analyzed retrospectively.Results Of all the 18 cases,11 cases are male,7 cases are female,male:female=1.6:1,patients age.The main symptoms were chest pain(15/18),dyspnea(12/18),cough(9/18);Through the radiologic findings,we could find 15 cases showing plenty of pleural effusion and with pleural thickening among 10 of them;I…
Objective Malignant mesothelioma is a mesothelium-derived carcinoma with high malignancy.Insulin-like growth factor and other growth factors were reported to be associated with the pathogenesis and prognosis of malignant mesothelioma.And some of these growth factors might be new targets of chemotherapy.
To assess the diagnosis of thoracoscopy in pleural mesothelioma. Methods Thoracoscopy with a single opening was performed using a rigid thoracoscopy under general anesthesia with neuroleptunalgesia.Biopsies were taken under visual control for optical microscopic examination. Result All of 8cases had underwent and toleranced the thoracoscopy.The biopsies were taken smoothly. General pathologic examenation the pleural mesothelioma. Conclusion Thoracoscopy is a safe and effective measure …
Masothelioma,a rare tumor,usually occurred in pleura,peritoneum and cardiac pericardium and so on.The majority is malignant,with short surviving period and high mortality.Malignant pleural mesothelioma is related with asbestos exposure,but the other causes are still unclear.This paper summarizes its epidemiology distribution,hazardous factors,the measures of control and prevention presently and so on.
To primarily evaluate the feasibility of functional magnetic resonance imaging(fMRI) on the location of brain regions related to cold stimulated toothache and its anticipation. Methods: A right handed patient with cold stimulated dentinalgia of the first right maxillary bicuspid was selected to perform the fMRI study. Other tooth pulp disease and oral metal restoration were excluded. A self-made water injection device was employed to induce toothache, and block designed BOLD functional…
Objective:To study the distribution of bacteria in halitosis patients.Methods:Test of bacteria restrain of Porphyromononas gingival isand Actinomyces Israelii was carried out by collecting plaque on tongue and periodontis poke from among 30 halitosis patients and 30 healthy people,for the quantitive cultivation of aerobe,microaerobe and anaerobe.Results:There were notable differences of tongue blade anaerobe and microaerobe(P<0 01) between halitosis patients(12 2±1 32)and healt h y people (9 5±1 24)…
Objective: To assess effect of periodontal therapy (scaling and root planing,SRP) on elimination of halitosis and reduction of volatile sulfur compounds(VSCs) level in mouth air,and to compare the effects of SRP combined with cleaning tongue coating (SRP CT) with those of SRP or CT on reducing VSCs. Methods: 117 periodontitis patients were divided into two groups according to organoleptic rating(OR): halitosis group(HG,85 cases) and no halitosis group(NHG,32 cases). VSCs level measurements before an…
