Purpose To investigate the clinicopathological changes, immuniohistochemistry and molecular genetics phenotypic charac-teristics of the alveolar soft part sarcoma ( ASPS) . Methods 16 cases of ASPS were studied with clinicopathological, cytochemistry technique and immunohistochemical staining, two cases of ASPS were studied by FISH. Results There were 6 males and 10 females with the age 8~58 years (median age 31. 7 years). The tumors were located at limbs, shoulder and back, tongue, vocal cords, lung, cervix, and ureter. The clinical manifestations of the patients was a slowly growing mass. Histopathologically the tumor showed typical organ-like or acinar-like structure with sinus-like blood vessels and the fibrous septa formation. Sometime the clear or abundant eosino-philic granular cytoplasm of the tumors were obvious. The tumor cells had a crystalline substance formation by PAS staining. The tumor cells were positive for TFE3 and Cathepsin K by immunohistochemical staining. The ASPL-TFE3 gene fusion detection of tumor cells were present. Conclusion ASPS often located on the limbs of young patients. It may misdiagnosed as malignant epithelial tumors, primary or metastatic adenocarcinoma and paraganglioma when the tumor locate on a rare anatomical parts or an organs, such as tongue, vocal cords, cervix, ureter, etc. It is valueable that the typical alveolar-like structure of the tumor and the expression for TFE3 and Cathepsin K for the pathological diagnosis of ASPS. It is an important indicator that the ASPL-TFE3 gene fusion detection by FISH for the tumor.

Objective:To explore the relationship between human papilloma virus (HPV)-DNA and cytomegalovirus (CMV)-DNA virus content and the risk factors of endometrial cancer (EC) and their prediction models.Methods:Fifty-eight patients with EC from January 2017 to June 2020 in Suzhou Hospital Affiliated to Anhui Medical University were selected as the observation group, and 58 patients with endometrial hyperplasia (EH) during the same period were selected as the control group according to the 1∶1 matching case control principle. The clinical data, HPV-DNA, CMV-DNA positive rate and virus content of the two groups were compared, and the independent variables with P<0.05 were included in the Logistic regression model through single factor analysis. The risk factors of EC were analyzed, and the correlation between HPV-DNA, CMV-DNA and EC risk factors were evaluated. Logistic regression model was evaluated using the likelihood ratio chi-square and goodness-of-fit test, and the receiver operating characteristic (ROC) curve was used to analyze the predictive value of the model to EC. Results:The proportion of patients with age ≥ 55 years old, body mass index (BMI)≥ 24 kg/m 2, a history of hypertension and diabetes, malignant tumor family history and hormone replacement therapy history in the observation group were higher than those in the control group: 72.41%(42/58) vs. 39.66%(23/58),70.69% (41/58) vs. 43.10%(25/58), 36.21%(21/58) vs. 10.34%(6/58), 31.03%(18/58) vs. 8.62%(5/58),29.31%(17/58) vs. 5.17%(3/58), 27.93%(17/58) vs. 8.62%(5/58), and the differences were statistically significant ( P<0.05). The positive rates of HPV and CMV, the contents of HPV-DNA and CMV-DNA in the observation group were higher than those in the control group: 62.07%(36/58) vs. 29.31%(17/58),81.03%(47/58) vs. 41.38%(24/58), (471.16 ± 33.58) copies/ml vs. (240.08 ± 17.41) copies/ml, (256.19 ± 24.77) copies/ml vs. (132.27 ± 13.20) copies/ml, the differences were statistically significant ( P<0.05). Age ≥ 55 years, BMI ≥ 24 kg/m 2, history of hypertension and diabetes, family history of malignant tumors, history of hormone replacement therapy, HPV positive, CMV positive were risk factors for EC ( P<0.05). HPV-DNA virus content was positively correlated with the age of EC patients, family history of malignant tumors, and history of diabetes ( P<0.05), the viral content of CMV-DNA was positively correlated with age, family history of malignant tumors, and history of hypertension ( P<0.05). According to the ROC curve drawn by the predicted value and the true value of the Logistic regression model, the area under the curve was 0.930 (95% CI 0.885 - 0.976), when the predictive probability of individual nosocomial infection>0.528, the prediction sensitivity was 84.48%, and the specificity was 89.66%. Conclusions:The occurrence of EC is related to many factors, and the content of HPV-DNA and CMV-DNA viruses are the risk factors of its occurrence. The overall predictive value of a Logistic regression model constructed based on EC pathological characteristics and the virus content of HPV-DNA and CMV-DNA is high, and it has clinical application prospects.

Objective When pathologists from hospitals at various levels encounters pathological sections diffcult to make clear diagosis, it is necessary to invite pathologists from higher hosiptals or special hospitals for pathologic consultation.In the study, we compared the pathological diagnosis of cases sent to other hospitals for pathological consultation with the original diagnostic result to analyze the differences by the evaluation on the impact of these differences on the treatment and prognosis of these patients, which would provide an effective evidence for the quality control of pathological diagnosis. Methods Cases initially diagnosed at the de-partment of Nanjing General Hospital and later sent to other hospitals for pathological consultation from 2010 to 2014 were collected. All the diagnostic results were examined by at least 3 senior pathologists to find exact diffrences between consultation results and origi-nal diagnostic results. Results Among 2055 cases, it was found that there were 1813 cases (88.2%) without diagnostic discrepan-cy, while 218 cases (10.6%) with minor diagnostic discrepancy and 24 cases (1.2%) with completely distinct diagnostic results. Conclusion The diagnostic results of the vast majority of consultation cases are in accordance with the original results, despite of di-agnostic discrepancies in some cases due to the complexity of disease. Expert consultation has reference for the pathological diagnosis of complicated cases, which also plays a potent supervisory role on the quality control of original pathologic results.

Objective To investigate the relationship between the optimal cutoff point of serum homocyste-ine(Hcy)and premature delivery in pregnant women ,and to analyze the influence of Hcy levels on the outcome of preterm infants. Methods Totally 114 cases of pregnant women were chosen as observation group and 103 cases of normal as control group. Hcy,D-D and hypersensitive C reactive protein were detected;analysis of the ROC curve was conducted by using the SPSS 13 software and the risk factors for preterm delivery were analyzed using logistic multivariate regression analysis. Results (1)The levels of Hcy,HS-CRP and D-D in preterm pregnant women were higher than those in control group and the difference was statistically significant (P < 0.05). (2) Logistic regression analysis showed that the relative risk coefficient(OR)of Hcy was 9.736,and the regression equation of premature birth probability was obtained.(3)ROC curve to evaluate the predictive value of Hcy in risk factors of preterm birth was 0.931;when Hcy was 13.8μmol/L,the Youden index was 0.784.(4)Elevated levels of Hcy in preterm women led to a marked increase in the likelihood of SGA. Conclusion When predicting risk factors for preterm birth,the best predictive cutoff value for Hcy is 13.8μmol/L,which is one of the independent risk factors for preterm birth.
