Abstract
Objective: To investigate the clinicopathological, immunophenotypic and molecular features of colorectal amphicrine carcinoma (AC). Methods: Eight cases of colorectal AC were collected at the Nanjing Drum Tower Hospital and Nanjing First Hospital, Nanjing, China from 2013 to 2020. The histopathological, immunohistochemical and molecular features were analyzed. The relevant literature was reviewed. Results: There were 6 males and 2 females, with an average age of 56 years (range 28-80 years). The tumor sites were as follows: 4 cases in sigmoid colon, 3 cases in rectum, and 1 case in transverse colon. Microscopically, there were three different patterns in the tumors, including nests with collagen hyperplasia, sheets of cells with scant stroma, and glandular or cribriform growth of goblet- or signet ring-like cells. The tumor cells generally had abundant cytoplasm with abundant mucin or eosinophilic granules. The nuclei were oval or irregular with fine chromatin and inconspicuous nucleoli. Mitotic figures were common. Neuroendocrine granules and mucin granules could be identified clearly under electron microscope. All cases showed frequent perineural and lymphovascular invasions, lymphatic metastasis, and advanced stage. Regarding immunohistochemical and specific stains, the tumor cells expressed more than two neuroendocrine markers, particularly CD56 and synaptophysin which were diffusely positive in 7 of the 8 cases. They also showed intracellular mucin in the amphicrine components which was positive for D-PAS. KRAS G12C or NRAS Q61 gene mutations were found in 2 patients. Among the six cases with complete follow-up, four of them died of the disease within three years of the diagnoses, while two were alive without known disease progression. Conclusions: Colorectal AC is a rare, distinct entity with both epithelial and neuroendocrine differentiation. It mainly occurs in the sigmoid colon and rectum. It typically has aggressive clinical courses, dismal prognosis and characteristic histological features and immunophenotype, which highlight the importance of recognizing this entity for clinicians and pathologists.

Abstract
Objective: To screen and analyze the key differentially expressed genes characteristics in nonalcoholic fatty liver disease (NAFLD) with bioinformatics method. Methods: NAFLD-related expression matrix GSE89632 was downloaded from the GEO database. Limma package was used to screen differentially expressed genes (DEGs) in healthy, steatosis (SS), and nonalcoholic steatohepatitis (NASH) samples. WGCNA was used to analyze the output gene module. The intersection of module genes and differential genes was used to determine the differential genes characteristic, and then GO function and KEGG signaling pathway enrichment analysis were performed. The protein-protein interaction network (PPI) was constructed using the online website STRING and Cytoscape software, and the key (Hub) genes were screened. Finally, R software was used to analyze the receiver operating characteristic curve (ROC) of the Hub gene. Results: 92 differentially expressed genes characteristic were obtained through screening, which were mainly enriched in inflammatory response-related functions of "lipopolysaccharide response and molecular response of bacterial origin", as well as cancer signaling pathways of "proteoglycan in cancer" and "T-cell leukemia virus infection-related". 10 hub genes (FOS, CXCL8, SERPINE1, CYR61, THBS1, FOSL1, CCL2, MYC, SOCS3 and ATF3) had good diagnostic value. Conclusion: The differentially expressed hub genes among the 10 NAFLD disease-related characteristics obtained with bioinformatics analysis may become a diagnostic and prognostic marker and potential therapeutic target for NAFLD. However, further basic and clinical studies are needed to validate.

Abstract
Objective: To propose a method of cervical cytology screening based on deep convolutional neural network and compare it with the diagnosis of cytologists. Method: The deep segmentation network was used to extract 618 333 regions of interest (ROI) from 5, 516 cytological pathological images. Combined with the experience of physicians, the deep classification network with the ability to analyze ROI was trained. The classification results were used to construct features, and the decision model was used to complete the classification of cytopathological images. Results: The sensitivity and specificity were 89.72%, 58.48%, 33.95% and 95.94% respectively. Among the smears derived from four different preparation methods, this algorithm had the best effect on natural fallout with a sensitivity of 91.10%, specificity of 69.32%, positive predictive rate of 41.41%, and negative predictive rate of 97.03%. Conclusion: Deep convolutional neural network image recognition technology can be applied to cervical cytology screening.

Abstract
Objective: To investigate the correlation between poorly differentiated clusters (PDCs) in colorectal adenocarcinomas with clinicopathological parameters and its clinicopathological significance. Methods: One hundred and eighty-three colorectal adenocarcinomas resected by radical proctocolecomy were collected at Nanjing Hospital(Nanjing First Hospital), Nanjing Medical University, from January to December 2017. There were 122 male and 61 female patients with age ranging from 42 to 89 years (mean of 68 years). Tumor diameter ranged from 2 to 14 cm (mean 4.5 cm). There were 124 colon cancers and 59 rectal cancers. The number and grade of PDCs in the colorectal adenocarcinoma were evaluated by H-E staining. The overall peritumoural inflammatory reaction was also evaluated. The relationship between PDCs and tumor grades and clinicopathological features and overall peritumoural inflammatory reaction of colorectal adenocarcinoma was analyzed. Results: Of 183 cases of colorectal adenocarcinoma, PDCs were seen in 104 cases (56.8%), of which 36 cases (19.7%) were grade 1, 28 cases (15.3%) were grade 2, and 40 cases (21.9%) were grade 3. PDCs were positively correlated with lymph node metastasis, vascular invasion, degree of differentiation, depth of invasion, and pTNM staging(P<0.05). The detection rate of PDCs in colon cancer was higher than that of rectal cancer(P<0.05). PDCs was unrelated to age, gender, tumor size, and degree of overall peritumoural inflammatory reaction (P>0.05). Among clinicopathological parameters, the grade of PDCs was correlated with lymph node metastasis and vascular invasion (higher than those without lymph node metastasis and vascular invasion, P<0.05); There was a positive correlation between the grade of PDCs and age, tumor differentiation and pTNM staging(P<0.05), and no significant difference between the grade of PDCs and gender, tumor size, tumor location, and depth of invasion was seen (P>0.05). There was no correlation between the grade of PDCs and the degree of overall peritumoural inflammatory reaction (P>0.05). Conclusions: PDC is a histological feature that predicts the aggressiveness of colorectal adenocarcinoma. Evaluation of PDC grade can better predict the biological behavior of colorectal cancer and more accurately guide the treatment and evaluate prognosis.

Abstract
Hemangioblastoma of the central nervous system occurs as sporadic tumors or as a part of von Hippel-Lindau (VHL) disease, an autosomal dominant hereditary tumor syndrome caused by a germline mutation in the VHL tumor suppressor gene. We screened a Chinese family with VHL for mutations in the VHL gene and evaluated a genetic test for diagnosing VHL disease and clinical screening of family members. DNA extracted from the peripheral blood of all live members and from tissue of deceased family members with VHL disease was amplified by polymerase chain reaction to 3 VHL gene exons. Mutations in the amplification products were compared against the Human Gene Mutation Database. The involvement of multiple organs among the kindred with VHL disease was confirmed by medical history and radiography. Of the 12 members of the 4-generation family, 5 were diagnosed with VHL disease. Patient age at the initial diagnosis was 26-36 years (mean = 31 years). The mean time was 15 (11-19 months) from symptom appearance to the first patient visit to the hospital. Sequence analysis revealed that the frameshift mutation 327del C (p.Gly39Alafs*26) in exon 1 affected all family members, but not the healthy individuals or 16 unrelated controls. Members without gene mutation showed no clinical manifestation of VHL disease. We detected a conserved novel frameshift mutation in the VHL gene of the family members that contributes to VHL. DNA analysis of VHL is advantageous for VHL diagnosis. We developed a quick and reliable method for VHL diagnosis.

Abstract
Between 1986 and 1995, 8307 leprosy patients have completed fixed-duration multidrug therapy (FD-MDT) and were followed annually for possible relapse. The mean relapse rate for multibacillary (MB) leprosy is 0.15/1000 person-years (py) and for paucibacillary (PB) 0.55/1000 py. There is no difference in the relapse rates between patients with or without chemotherapy before FD-MDT. In MB patients, the five relapses occurred between 4 and 7 years; in PB patients, five relapses occurred at 4-5 years after FD-MDT. Six additional PB relapses self-reported 1-4 years after the 5-year surveillance period and were not included in the relapse rates. Most PB patients relapsed into MB due to wrong classification and insufficient therapy. For the known 62 irregular MB patients the cumulative relapse rate is 6.5%.

Abstract
Thirty-three active multibacillary patients from nine counties of Weifang Prefecture, Shandong Province, and 47 active cases from Menla County, Yunnan Province, People's Republic of China, were treated with 24 and 27 months of multidrug therapy (MDT), respectively, in 1983. Clinical assessments, smears, and histopathologic examinations were carried out independently by study teams from the Institutes of Dermatology of these two provinces. Reexaminations at 12-14 months and at termination of therapy showed marked improvement, and there was continued improvement at 12-18 and 33 months on follow up. Conversion of the bacterial index to negativity was 0/33, 5/47 for the patients from Shandong and Yunnan provinces, respectively, at the end of MDT and 2/33 at 12 months' and 17/47 at 18 months' follow up, which increased to 21/33 and 26/44 at 33 months' follow up. Regression of specific infiltration was about 21%-100% after 24-27 months of MDT; further regression to 95%-100% occurred at 33 months' follow up.
