Application of an Innovative Embedding and Cooling Component in the Critical Steps of Fragmented Tissue Pathological Diagnosis.

This study aimed to explore the application value of an innovative embedding and cooling component in the critical steps of fragmented tissue pathological diagnosis. Eighty small and fragmented tissue samples were collected and randomly divided into two groups. The embedding qualification rate and embedding efficiency were compared between the two groups.

Atypical Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis simulating lymphadenitis on F-FDG PET/CT and its differential diagnosis.

Diagnosis of Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) is challenging as its clinical presentation is atypical. Here we present a case of atypical EBV-HLH simulating lymphadenitis on fluorrine-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT), with a view to consider this kind of EBV-HLH as a possible differential diagnosis in lymphadenitis. A 68 years old male who had episodic fever accompanied by weight loss and weakness for two weeks was studied.

[Clinical efficacy of the fine needle aspiration of the cell block in the diagnosis of parotid gland masses].

Objective: To investigate the clinical significance of cell blocks obtained by ultrasound-guided fine needle aspiration in diagnosing parotid gland masses.

Methods: Cell blocks were made in 285 parotid gland masses by ultrasound-guided fine needle aspiration. Diagnosis was conducted using the cell blocks.

[Application value of fine needle aspiration and cell block in preoperative diagnosis of thyroid cancer and discrimination of follicular tumor].

Objective: To study the application value of fine needle aspiration and cell block combined with molecular markers in early diagnosis of thyroid cancer and discriminate follicular tumor before operation.

Methods: Fine needle biopsy of thyroid nodules was guided by color ultrasound, then the sample acquired was used to make smear and the rest to make cell block. The pathological diagnosis on smear, cell block or combination of both was made respectively.

[Expressions of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in ectopic and eutopic endometrium].

Objective: To study the expression of matrix metalloproteinase-9(MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in ectopic and eutopic endometrium in patients with endometriosis.

Methods: The expressions of MMP-9 and TIMP-1 in ectopic and eutopic endometrium were detected by immunohistochemistry streptavidin-biotin peroxidase (SP) method in 45 patients with endometriosis (study group) and in 32 patients with uterine fibroid (control group).

Results: In the ectopic and eutopic endometrium of group and in the control group endometrium, the expression of MMP-9 was respectively 0.
