Clinicopathological features of meningioangiomatosis associated with meningioma: a case report with literature review.

Aim. To analyze the clinicopathological features of meningioangiomatosis (MA) associated with meningioma. Methods.

[Pulmonary epithelioid hemangioendothelioma: a clinicopathological analysis].

Objective: To report 3 cases of pulmonary epithelioid haemangioendothelioma (PEH) and therefore to improve the understanding of this tumor.

Methods: The clinical pathological features of 3 cases of PEH were described and related literatures were reviewed.

Results: The etiology of this rare disease remained unknown.

[Giant cell tumor of temporal bone and mandibular condyle: a case report].

Giant cell tumor of bone (GCTB) seldom occurs in the head or face. This article reported a case that GCTB occurred simultaneously in the temporal bone and mandibular condyle, and analyzed their clinical and pathological features.

[Infection of cytomegalovirus and herpes simplex virus and morphology of the infected spermatogenic cells in infertile men].

Objective: To study the infection of human cytomegalovirus (HCMV) and herpes simplex virus type II (HSV-I) and the morphological characteristics of the infected spermatogenic cells in the semen of infertile men.

Methods: We washed and concentrated the spermatogenic cells obtained from 83 semen samples of infertile men, extracted DNA and then screened HCMV and HSV-II by polymerase chain reaction (PCR). Immunocytochemistry (ICC) was used to detect the expression of correlative virus antigens of the positive semen cells, and the cytology smear was employed to observe the morphological changes of the spermatogenic cells under the microscope after cytology staining.

[Clinical and pathologic features of malignant myoepithelioma of salivary glands].

Objective: To analyze the clinical features, morphology and biologic behavior of primary malignant myoepithelioma (MME) of salivary glands.

Methods: The H&E sections of 16 MME cases were reviewed. Immunohistochemical study using EnVision method for cytokeratin (CK), epithelial membrane antigen (EMA), vimentin, S-100 protein, desmin, muscle-specific actin (MSA), smooth muscle actin (SMA), Myo, proliferation cell nuclear antigen (PCNA), leukocyte common antigen (LCA) and glial fibrillary acidic protein (GFAP) was carried out.

[Pathological changes of lungs in patients with severity acute respiratory syndrome].

Objective: To evaluate the progression in morphologic changes of lungs in SARS patients.

Methods: Four cases of SARS with lung tissue samples available (including one for ultrastructural examination) were enrolled into the study. Histochemical study for VG, Masson, reticulin, orcein, PAS, sirius red stains and immunohistochemical study for vimentin, desmin, smooth muscle actin, HHF-35, CD34, F8, collagen types I and III were also performed.

[Sclerosing epithelioid fibrosarcoma: a clinicopathologic study of eight cases].

Objective: To study the clinicopathologic features, immunophenotype and differential diagnosis of sclerosing epithelioid fibrosarcoma (SEF).

Methods: Eight cases of SEF were investigated by light microscopy and immunohistochemistry.

Results: There were five males and three females.

[Expression and action of vascular endothelial growth factor and its receptor in a rat model of retinopathy of prematurity].

Objective: To explore the expression of vascular endothelial growth factor (VEGF) and its receptors (flt-1 and flk-1) in the retina of retinopathy of prematurity (ROP), and its relation to the alteration of retinal blood vessels.

Methods: Eighty-six newborn Sprague-Dawley rats were randomly divided into hyperoxia and air groups, then each group was further divided into 1, 3, 7 and 14 days subgroups. The rats in hyperoxia group inhaled 75% oxygen and ROP model was thus set up.

[Pathological and ultramicrostructural changes of tissues in a patient with severe acute respiratory syndrome].

Objective: To study the morphological, ultramicrostructural and pathological changes of tissues from a patient with severe acute respiratory syndrome (SARS).

Methods: One autopsy case of diagnosed SARS was investigated. Lung puncture was performed immediately after the patient died, and the autopsy was done after 12 h.

[Effects of Helicobacter pylori infection on porcine gastric epithelial cell proliferation].

Objective: To investigate the association between porcine gastric epithelial cell proliferation and Helicobacter pylori (Hp) infection.

Method: Animal models of gastritis associated with Hp infection were established using "Chinese No.1 pigs".
