[Clinicopathologic study of von Hippel-Lindau syndrome-related and sporadic hemangioblastomas of central nervous system].

Objective: To study clinicopathologic features, diagnosis, treatment and prognosis of von Hippel-Lindau (VHL) syndrome-related and sporadic hemangioblastomas of the central nervous system (CNS-HB).

Methods: Histopathological, ultrastructural, immunohistochemical (EnVision method) and clinical features of 21 VHL syndrome and 63 sporadic CNS-HB cases were studied with correlation of the available follow-up information.

Results: Twenty-one VHL patients accompanied with a total of 87 CNS-HBs, including one patient of developing 12 HBs within 13 years.

[Analysis of 12 206 cases of external pathology consultation].

Objective: To study the concordance rate of external pathology consultation referred by hospitals of various scales and to evaluate the value of such practice.

Methods: A total of 12 206 external pathology consultation cases referred by outside institutions were encountered during a 5-year period. The final pathologic diagnoses in 3289 cases were compared with the original interpretations.

[Clinicopathological study of 5 cases of proximal-type epithelioid sarcoma].

Objective: To investigate the clinicopathological characteristics, diagnosis and differential diagnoses of proximal-type epithelioid sarcoma (PES).

Methods: Five cases of PES were retrieved from pathology files. Clinical, pathologic and immunohistochemical features of the tumors were reviewed.

[Clinicopathologic study of pilocytic astrocytoma].

Objective: To study clinicopathologic features, treatment and prognosis of pilocytic astrocytoma (PA).

Methods: Histopathological, ultrastructural, immunohistochemical (EnVision method) and clinical features of 68 cases of PA were studied by microscopic investigation with correlation of clinical follow-up information when available.

Results: Thirty-five male patients and 33 female patients were studied.

[A study of the histopathological characteristics of nontuberculous mycobacteria lymphadenitis].

Objective: To describe the distinctive histopathological changes of nontuberculous mycobacteria lymphadenitis.

Methods: An experimental animal model of nontuberculous mycobacteria lymphadenitis was established and the histopathological changes were observed by light microscope. The paraffin imbedded tissue samples from patients suspected of having lymphoid tuberculosis were also detected by triplex polymerase chain reaction and studied by light microscope.

[Clinicopathologic study of pleomorphic xanthoastrocytoma of brain].

Objective: To study the clinicopathologic features, treatment response and prognosis of pleomorphic xanthoastrocytoma (PXA).

Methods: Amongst a total of 6 287 patients with central nervous system tumors encountered in Nanjing General Hospital of PLA during the period from 1980 to 2004, 15 cases of PXA were found. Two additional cases of PXA were also retrieved from the authors' consultation files.

[A clinicopathologic study of dysembryoplstic neuroepithelial tumor].

Unlabelled: OBJECTIVE To study the clinicopathologic features, radiologic findings, treatment modalities and prognosis of dysembryoplastic neuroepithelial tumor (DNT).

Methods: The clinical features, histopathologic findings, immunohistochemistry and electron microscopy of 18 cases of DNT were analyzed. Results Among the 18 cases studied, 14 were males and 4 females.

Evaluation of various solutions for small bowel graft preservation.

AIM:To elucidate the effect of various solutions for small bowel graft preservation in pigs under hypothermic storage.METHODS:The swine segmental small bowel graft was autotransplanted after it was preserved with lactated Ringer's (LR), Euro-Collins (EC), hyperosmolarity citrate adenine (HC-A) and WMO-1 solutions for 10,18 and 24 hours,respectively.The recipient survival rate, morphological structure, graft mucosal energy substances and Na( +) -K(+) ATPase activity were studied,and graft absorption was estimated with D-xylose absorption test.
