Abstract
Objective: To validate the diagnostic performance of the Paris system for reporting urinary cytology (TPS). Methods: A total of 7 046 urine cytology samples from 3 402 patients collected in the Department of Pathology, Beijing Hospital, China from January 2020 to January 2022 were analyzed. 488 patients had a biopsy or resection specimen during the follow-up period of 6 months. The sensitivity, specificity, risk of malignancy (ROM) and risk of high-grade malignancy (ROHM) of the TPS were evaluated using histological diagnosis as the golden standard. Results: Among the 7 046 samples, high-grade urothelial carcinoma (HGUC) accounted for 5.7% (399/7 046), suspicious for high-grade urothelial carcinoma (SHGUC) for 3.2% (227/7 046), atypical urothelial cells (AUC) for 8.4% (593/7 046), and negative for high-grade urothelial carcinoma (NHGUC) for 72.9% (5 139/7 046) including low-grade urothelial neoplasm (LGUN) for 0.8% (59/7 046) and insufficient samples for 9.8% (688/7 046). 488 patients had a bladder biopsy or resection in the follow-up of six months, including 314 males and 174 females, aged 27 to 92 years (average, 66 years). The ROHM of TPS was 94.7% in HGUC, 83.3% in SHGUC, 41.3% in AUC and 18.8% in NHGUC. The sensitivity and specificity of urine cytology were 70.1% (169/241) and 97.0% (162/167), respectively. The negative predictive value of NHGUC was 69.2% (162/234). Conclusions: The study has shown that TPS classification has high sensitivity and specificity, high ROHM for HGUC and SHGUC, and high negative predictive value for NHGUC. The application of TPS reporting system can better interpret the clinical significance of cytology samples, improve the accuracy of urine cytopathology and ensure continuous diagnostic consistency.

Abstract
Objective: To explore the application of manual screening collaborated with the Artificial Intelligence TPS-Assisted Cytologic Screening System in urinary exfoliative cytology and its clinical values. Methods: A total of 3 033 urine exfoliated cytology samples were collected at the Henan People's Hospital, Capital Medical University, Beijing, China. Liquid-based thin-layer cytology was prepared. The slides were manually read under the microscope and digitally presented using a scanner. The intelligent identification and analysis were carried out using an artificial intelligence TPS assisted screening system. The Paris Report Classification System of Urinary Exfoliated Cytology 2022 was used as the evaluation standard. Atypical urothelial cells and even higher grade lesions were considered as positive when evaluating the recognition sensitivity, specificity, and diagnostic accuracy of artificial intelligence-assisted screening systems and human-machine collaborative cytologic screening methods in urine exfoliative cytology. Among the collected cases, there were also 1 100 pathological tissue controls. Results: The accuracy, sensitivity and specificity of the AI-assisted cytologic screening system were 77.18%, 90.79% and 69.49%; those of human-machine coordination method were 92.89%, 99.63% and 89.09%, respectively. Compared with the histopathological results, the accuracy, sensitivity and specificity of manual reading were 79.82%, 74.20% and 95.80%, respectively, while those of AI-assisted cytologic screening system were 93.45%, 93.73% and 92.66%, respectively. The accuracy, sensitivity and specificity of human-machine coordination method were 95.36%, 95.21% and 95.80%, respectively. Both cytological and histological controls showed that human-machine coordination review method had higher diagnostic accuracy and sensitivity, and lower false negative rates. Conclusions: The artificial intelligence TPS assisted cytologic screening system has achieved acceptable accuracy in urine exfoliation cytologic screening. The combination of manual screening and artificial intelligence TPS assisted screening system can effectively improve the sensitivity and accuracy of cytologic screening and reduce the risk of misdiagnosis.

Abstract
Objective: To investigate the level of nucleic acid oxidation in myocardial tissue of patients aged over 85 with heart failure with preserved ejection fraction (HFpEF) and the correlation with myocardial amyloid deposition. Methods: This was a retrospective case-control study. Data of patients≥85 years old who underwent systematic pathological autopsy in Beijing Hospital from 2003 to 2017 were retrospectively collected. Twenty-six patients were included in the HFpEF group and 13 age-and sex-matched patients who had not been diagnosed with heart failure and died of non-cardiovascular diseases served as the control group. The left ventricular myocardium slices of both groups were semi-quantitatively analyzed using immunohistochemical staining of 8-oxidized guanine riboside (8-oxo-G) and 8-oxidized guanine deoxyriboside (8-oxo-dG) to evaluate the oxidation of RNA and DNA in cardiomyocytes. Using the median of the mean absorbance value of 8-oxo-G immunohistochemical staining as the cut-off value, patients were divided into high-absorbance group and low-absorbance group. Congo red staining was used to compare myocardial amyloid deposition between the two groups. Results: The mean age of patients in HFpEF group was (91.8±3.7) years, 24 (92.3%) were males. The mean age of patients in control group was (91.7±3.7) years old, 11 (84.6%) were males. The median mean optical absorbance value of 8-oxo-G immunohistochemical staining of myocardium was significantly higher in HFpEF patients than in control group (0.313 8 (0.302 2, 0.340 6) vs. 0.289 2 (0.276 7, 0.299 4), Z=-3.245, P=0.001). The median mean absorbance value of 8-oxo-dG immunohistochemical staining of myocardial tissue was similar between the two groups (0.300 0 (0.290 0, 0.322 5) vs. 0.300 0 (0.290 0, 0.320 0), Z=-0.454, P=0.661). Proportion of patients with moderate and severe cardiac amyloid deposition was significantly higher in the high-absorbance group than in the low-absorbance group ((85.0%, 17/20) vs. (31.6%, 6/19), P=0.001). Conclusion: The RNA oxidation degree of myocardium in HFpEF patients is higher than that in elderly people without heart failure. Degree of myocardial amyloid deposits is higher in patients with high levels of RNA oxidation.

Abstract
Objective: To assess the feasibility of nuclear score combined with cyclin D1 immunocytochemistry in classifying indeterminate thyroid nodules with fine-needle aspiration (FNA) cytological diagnosis of Bethesda category Ⅲ-Ⅴ. Methods: A consecutive cohort of 118 thyroid FNA specimens with indeterminate diagnosis (TBSRTC category Ⅲ-Ⅴ) and available histopathologic follow-up data were collected between December 2018 and April 2022 at the Department of Pathology, Beijing Hospital, China. These cases were subjected to cytological evaluation and cyclin D1 immunocytochemistry. The optimal cut-off points of a simplified nuclear score and the percentage of cyclin D1-positive cells for the diagnosis of malignancy or low-risk neoplasm were determined using the receiver operating characteristic (ROC) curves and area under the ROC curve (AUC). The specificity, sensitivity, positive predictive value (PPV) and negative predictive value (NPV) of nuclear score and cyclin D1 immunostaining were evaluated from the crosstabs based on cut-off points. The diagnostic accuracy of simplified nuclear score combined with cyclin D1 immunostaining was estimated using ROC curve analysis. Results: Nuclear grooves, intra-nuclear inclusions and chromatin clearing were more commonly found in malignancy/low-risk neoplasms than benign lesions (P=0.001, P=0.012 and P=0.001 respectively). A cut-off point of≥2 for the simplified nuclear score was sensitive for defining malignancy/low-risk neoplasm, and its PPV, NPV, sensitivity and specificity were 93.6%, 87.5%, 99.0% and 50.0% respectively. A positive cut-off point of 10% positive thyroid cells in cyclin D1 immunostaining demonstrated sensitivity of 88.5%, specificity of 100%, PPV of 100% and NPV of 53.8% for correctly detecting thyroid malignancy or low-risk neoplasm. The sensitivity and PPV of simplified nuclear score combined with cyclin D1 immunostaining were 93.3% and 100%, respectively. Both specificity and NPV were maintained at high levels (100% and 66.7%, respectively). The diagnostic accuracy of simplified nuclear score combined with cyclin D1 immunostaining in detecting thyroid malignancy/low-risk neoplasm was increased to 94.1% compared to using either of them alone. Conclusions: Combing simplified nuclear score and cyclin D1 immunostaining on FNA cytology specimens can increase the diagnostic accuracy in classifying thyroid nodules of indeterminate cytological categories. Thus, this supplementary approach provides a simple, accurate, and convenient diagnostic method for cytopathologists so that may reduce unnecessary thyroidectomies.

Abstract
Objective: To assess the value of cyclin D1 immunocytochemistry combined with a small panel molecular analysis in indeterminate cytological diagnosis of Bethesda category Ⅲ-Ⅴ. Methods: A consecutive cohort of 96 thyroid FNA specimens with indeterminate diagnosis (TBSRTC category Ⅲ-Ⅴ) and available histopathologic follow-up data were collected between December 2018 and December 2021 in Department of Pathology, Beijing Hospital. The cases were evaluated by cyclin D1 immunocytochemistry and molecular testing of BRAFV600E or a small panel of markers (BRAF, N-RAS, H-RAS, K-RAS and TERT) in the FNA specimens. The identification of the optimal cut-off point of cyclin D1 for the diagnosis of malignancy was evaluated using the receiver operating characteristic (ROC) curves and the assessment of the area under the ROC curve (AUC). The specificity, sensitivity, positive predictive value (PPV) and negative predictive value (NPV) of all these markers were evaluated with the crosstabs and significance was calculated. Results: Ninty-six patients with 96 thyroid nodules were enrolled, including 42 cases of TBSRTC-III, 10 cases of TBSRTC-IV and 44 cases of TBSRTC-V. There were 79 females and 17 males with a median age of 47 years (range, 25 to 75 years). A 7.5% cut-off value for positive cyclin D1 nuclear immunostaining in thyroid cells demonstrated 100% PPV, 57.1% NPV, 81.0% sensitivity and 100% specificity for thyroid malignancy diagnosis. The sensitivity of the BRAFV600E mutation test or combined with a small panel test alone for thyroid malignancy diagnosis were 65.5% and 69.0% respectively. The sensitivity for thyroid malignancy diagnosis increased to 94.0% and 95.2% respectively when combining the cyclin D1 immunocytochemistry with the molecular test, and the specificities remained 100% and 91.7% respectively.The accuracy of cyclin D1 immunocytochemistry combined with a small panel of molecular test in detecting thyroid malignancy increased to 94.8% compared to using these markers alone. Conclusions: The addition of cyclin D1 immunocytochemistry and a small panel of molecular testing to FNA cytology can increase the sensitivity and NPV of cytology in indeterminate categories, and this supplementary approach provides a simple, accurate and convenient diagnostic method for reducing unnecessary thyroidectomies.

Abstract
Background The research into the recurrence of cough variant asthma (CVA) in congenital heart disease (CHD) are few in number. The purpose of this study is to investigate the effect of CHD on the risk of the recurrence of CVA. Methods This study was a retrospective cohort study of 489 children with CVA aged between one and 14 years, of whom 67 had CHD complicated with CVA and 134 had CVA without CHD at a ratio of 1:2 according to age, sex and index year. The adjusted hazard ratio (aHR) of CVA recurrence in both the CHD cohort and the non-CHD cohort was determined by multivariate analysis using the Cox proportional hazard regression model. Results Adjusting for CHD classification, Mycoplasma pneumonia (MP) infection and immunoglobulin E (IgE) sensitization, the recurrence hazard of CVA in the complex congenital heart disease (CCHD) group (aHR = 3.281; 95% CI 1.648–6.530; P < 0.01) was significantly higher than that in the simple congenital heart disease group (aHR = 2.555; 95% CI 1.739–3.752; P < 0.01). Further, children with IgE sensitization (aHR = 2.172; 95% CI 1.482–3.184; P < 0.01) had a higher recurrence hazard of CVA than those without IgE sensitization, and children with MP infection (aHR = 1.777; 95% CI 1.188–2.657; P < 0.01) had a higher recurrence hazard of CVA than those without the MP infection. Conclusion The hazard of recurrent CVA is higher in children with CHD, especially in the CCHD children. In addition, those children with IgE sensitization or a MP infection had an increased hazard of recurrent CVA.

Abstract
Objective: To elucidate the clinicopathological characters and prognostic factors of invasive micropapillary carcinoma of the breast (IMPC) by compared with invasive ductal carcinoma, not otherwise specified of the breast (IDC). Methods: The retrospective study was performed with female patients who had undergone curative resection for breast cancer without neoadjuvant chemotherapy from June 2008 to April 2016 in Breast Center of Beijing Hospital. Forty-seven mixed or pure IMPC patients and 93 pure IDC patients(admitted in the same center from October 2008 to January 2016 ) were matched for tumor stage, nodal status and age. Follow-up was done every 3 to 6 months postoperatively. The deadline was July 31, 2016. The curves of disease free survival and overall survival were drawn by the Kaplan-Meier method, and survival rates were compared by means of the Log-rank test. Potential prognostic variables that were identified on univariate analysis were analyzed with Cox's proportional hazards regression model for multivariate analysis. The χ(2) test or Fisher's exact test was used to compare distributions across 2 groups and the Mann-Whitney U test or t test was used to analyze the medians or means of 2 groups. Results: With exact matches, the rates of lymphovascular invasion (LVI) (29.8% vs. 12.9%, χ(2)=5.885, P=0.015)and histological grade 3 (40.4% vs. 21.5%, χ(2)=-2.690, P=0.007) were both significantly higher in patients with IMPC than that in IDC group, but the survival between the two pathological types were not significantly different (all P>0.05). The percent of IMPC component didn't influence the clinicopathologic characters (all P >0.05), but a significantly longer median disease free survival (χ(2)=11.731, P=0.001) when the patients had more than 50% of IMPC component was found. Conclusions: Higher rates of LVI and histological grade 3 were found in IMPC than that in IDC, but the survival was comparable between the two groups. A longer DFS occurred in patients with IMPC component more than 50%.

The curves of disease free survival (DFS) and overall survival (OS) were drawn by Kaplan-Meier method, and survival rates were compared by means of the Log-rank test. Potential prognostic variables which were identified on univariate analysis were analyzed with Cox's proportional hazards regression model for multivariate analysis. Results: More lymph nodes were involved in IMPC group (χ(2)=12.168, P=0.007) which led to more later stage in this group (χ(2)=8.950, P=0.011). IMPC group displayed a significantly increased rate of lymphovascular invasion (LVI) compared to IDC group (χ(2)=13.511, P = 0.001). The expression rate of estrogen receptor (ER) and progesterone receptor (PR) was higher in IMPC group than that in IDC group (89.8% vs. 76.3% and 88.1% vs. 70.7%, respectively, χ(2)=5.786, 8.332, all P<0.05). In multivariate analysis performed with the variables found significant in univariate analysis, the only variable found significantly affecting DFS of IMPC group was the T stage (T1-2 and T3-4, OR=5.217, 95%CI: 1.401 to 19.430, P=0.014), while in IDC group, pathological stage (stage Ⅰ to Ⅱ and stage Ⅲ to Ⅳ, OR=1.870, 95% CI: 1.262 to 2.771, P=0.002), lymph node positive ratio (LNR) (OR=2.222, 95%CI: 1.561 to 3.162, P=0.000), PR (OR=1.856, 95%CI: 1.118 to 3.082, P=0.017), and age (<50 years old and ≥50 years old, OR=0.695, 95%CI: 0.488 to 0.989, P=0.043) were prognostic factors. There were two variables found significantly affecting OS of IMPC group, which were T stage (OR=3.713, 95%CI: 1.539 to 8.959, P=0.004) and LNR (OR=2.850, 95%CI: 1.033 to 7.862, P=0.043). While in IDC group, LNR was the only variable found significantly affecting OS (OR=2.129, 95%CI: 1.324 to 3.425, P=0.002). Compared with IDC, the patients with IMPC were more likely to have local or regional recurrence (P=0.006). Although the median DFS interval was longer in IDC group (χ(2)=9.739, P=0.002), the median OS interval was comparable between the two groups (χ(2)=0.787, P=0.375). Conclusion: Although IMPC has lymphotropic feature, tendency of LVI and local or regional recurrence, it has an OS which is comparable with IDC.

Abstract
Primary adenocarcinoma of the vulva is uncommon, and cloacogenic adenocarcinoma of the vulva is extremely rare. Here the authors report a vulvar neoplasm, arising in continuity with the epidermis, characterized by villoglandular architecture, and mucinous-type ep- ithelium with intestinal differentiation (goblet cells). Histochemistry, immunohistochemistry, and gene mutation analysis revealed a colon-like pattern, except for CK7 expression. Extensive workup failed to reveal other primary cancers. In order to provide a much bet- ter experience for diagnosis, the authors compared the previously published cases with the present case regarding clinical presentation and histopathologic aspect. They believe that the notion of the tumor arising from cloacal remnants is a more acceptable viewpoint, and its behavior is mostly indolent. In the present case, a wide local excision was sufficient for radical cure.

Abstract
OBJECTIVE To evaluate the roles of cytomorphology and immunohistochemistry in distinguishing between basaloid squamous cell carcinoma (BSC) and small cell carcinoma (SCC) of lung. METHODS The direct smears and/or liquid-based cytology preparation (ThinPrep) of bronchial brushing/washing and fine-needle aspiration (FNA) specimens from 17 cases of biopsy-proven BSC of lung were retrospectively reviewed and compared with those from 17 cases of SCC. The cytomorphologic parameters analyzed included proportion of cohesive cell clusters, cell palisades/rosettes, adenoid cystic features, crushing artifact, nuclear maximum diameter, nuclear molding, scantiness of cytoplasm,"salt-and-pepper"nuclei, distinct nucleoli, spindly configuration, individual cell keratinization, necrosis, hyaline material, apoptosis and mitotic activity. Immunocytochemical/immunohistochemical study of 25 cases was performed. Ten FNA samples of basaloid squamous cell carcinoma were also analyzed for epidermal growth factor receptor mutations in exons 18, 19, 20 and 21 using amplification refractory mutation system. RESULTS Most of the 17 BSC cases (15/17) showed a predominance of tightly cohesive tumor cell clusters. The proportion of isolated tumor cells was high in SCC (more than 60% in 14 cases). The nuclear maximum diameter of BSC was slightly larger than that of SCC (9 to 11 μm in BSC versus 7 to 9 μm in SCC)."Salt-in-pepper"nuclei, nuclear molding and crushing artifact were detected in all SCC cases (15/17, 17/17 and 14/17, respectively). These features were only occasionally found in BSC group. Nucleoli were present in BSC and rarely (2/17) in SCC. Only 9 of 17 BSC cases showed individual cell keratinization. The differences in the above-mentioned cytomorphologic features were statistically significance (P<0.05). The results of immunohistochemistry performed on the cell block sections and immunocytochemistry performed on the ThinPrep slides were identical to that performed on the corresponding biopsy specimens. The tumor cells in BSC were consistently positive for CK5, p40 and p63. TTF1, chromogranin A, synaptophysin and CD56 were positive in most of SCC. One of SCC cases showed focal PAX5 expression. No EGFR mutations were detected in the 10 BSC cases studied. CONCLUSIONS Selected cytomorphologic features, including presence of cohesive cell clusters, larger nuclear size, distinct nucleoli, lack of crushing artifact, absence of nuclear molding and presence of individual cell keratinization, are helpful in diagnosing BSC on cytology specimens. Immunohistochemistry using a panel of TTF1, CK5, p40/p63 and chromogranin A/synaptophysin/CD56 provides further clues in differential diagnosis between BSC and SCC. EGFR mutation study is often negative in lung BSC.
