ABSTRACT
Objective To explore the clinical value of new rapid pathological diagnosis technology in the examination of cervical lesions in primary medical institution.Methods In the Affiliated Hospital of Yangzhou University,25 cases of cervical scraping and 22 cases of cerrical biopsy were selected.Twenty-five cases of cervical scraping scraped two wipers during operation,the results were compared with conventional pathological techniques and new rapid pathological diagnosis techniques.Twenty-two cases of cervical biopsy used a new rapid pathological diagnosis technique to perform cytological diagnosis of biopsy tissue rolls in biopsy operation.According to the results of rapid pathological diagnosis,the biopsy operation plan was adjusted to analyze the clinical value of the new rapid pathological diagnosis technique in cervical lesions in primary medical institution.Results The new rapid pathological diagnosis technology required less space and no pollution,and the diagnosis took about 2-3 min,which did not affect the normal inspection operation.Twenty-five cases of cervical scraping were produced with new rapid pathological diagnosis technique,and the quality of cervical scraping produced with conventional pathological technique was consistent,which could satisfy the needs of pathological cytological diagnosis;twenty-two cases of cervical biopsy under the vaginal device were assisted by this technology and it could increase the positive rate of the first biopsy.Conclusion Cervical scraping and cervical biopsy are still the main methods for cervical lesions examination in primary hospitals.The new rapid pathological diagnosis technology can provide the real-time pathological diagnosis of cervical scraping,improve the positive detection rate of the first biopsy of cervical biopsy,and the cost is low,suitable for promotion in primary medical institution.

ABSTRACT
Objective To investigate the clinicopathological characteristics, differential diagnosis and biological features of natural killer (NK)/T cell lymphoma in nasal cavity. Methods The data of 17 cases of nasal NK/T-cell lymphoma from Department of Pathology in the Affiliated Hospital of Yangzhou University between September 2007 and July 2017 were collected. Pathologic analysis including clinical symptoms, pathomorphism and immunophenotyping was performed, and the literatures were also analyzed. Results The clinical symptoms of the patients with nasal NK/T cell lymphoma were not obvious, which were accompanied by nasal congestion,runny nose,and blood in the runny nose.Pathologic examination showed obvious necrosis and inflammatory background of different levels. There were allotypic lymphocytes in the inflammatory background, nuclear irregular distortion or folding, unapparent nucleoli and visible nuclear fission, tumor cell growth for the center with blood vessels resulting in invasion and damage to blood vessels, in which normal lymphocytes,plasma cells and tissue cells could be seen.CD3,CD43,CD56,TIA-1,granzyme B,perforin and other markers were expressed in the tumor cells, and EB virus in situ hybridization was positive. Conclusions Nasal NK/T cell lymphoma is rare,with high incidence of invasive tumor, high recurrence rate, poor prognosis and easy misdiagnosis, which needs immunohistochemistry for differential diagnosis. Treatment is mainly based on radiotherapy and chemotherapy.
ABSTRACT
Objective@#To study the clinicopathologic features, the differential diagnosis and the expression of STAT6 in solitary fibrous tumor (SFT).@*Methods@#Eighty cases of SFT were evaluated. The expression of STAT6, CD34, CD99 and bcl-2 protein was studied in these cases and in other groups of soft tissue tumors by immunohistochemical EnVision method. The results were analyzed and relevant literature were reviewed.@*Results@#The expression rate of STAT6 in SFT was 97.5% (78/80) and that in other soft tissue tumors was 3.3% (3/90). The difference was significant (P<0.05). The expression rates of CD34, CD99 and bcl-2 were 88.8% (71/80), 76.3% (61/80) and 75.0% (60/80) in SFT, respectively, which were significantly different from STAT6 expression rate (P<0.05).@*Conclusions@#The expression of STAT6 in SFT has high sensitivity (97.5%) and specificity (96.7%). The expression of STAT6 in SFT is higher than that of CD34, CD99 and bcl-2. STAT6 may be a useful marker for clinical diagnosis of SFT.
