Case report and literature review: Rare male aggressive angiomyxoma of the scrotum.

Aggressive angiomyxoma (AAM) is an uncommon locally infiltrative tumor that frequently occurs in the pelvic soft tissues of female patients; it has a high rate of local recurrence. However, AAM is extremely rare in males. Herein, we present the case of a 70-year-old man with a gradually enlarging painless mass in the scrotum.

Endoscopic classification and pathological features of primary intestinal lymphangiectasia.

Background: The appearance of the intestinal mucosa during endoscopy varies among patients with primary intestinal lymphangiectasia (PIL).

Aim: To classify the endoscopic features of the intestinal mucosa in PIL under endoscopy, combine the patients' imaging and pathological characteristics of the patients, and explain their causes.

Methods: We retrospectively analyzed the endoscopic images of 123 patients with PIL who were treated at the hospital between January 1, 2007 and December 31, 2018.

Polycyclic Arenes Dihydrodinaphthopentacene-based Hole-Transporting Materials for Perovskite Solar Cells Application.

In this paper, two D-π-D type compounds, C1 and C2, containing dihydrodinaphthopentacene (DHDNP) as a π-bridge, p-methoxydiphenylamine and p-methoxytriphenylamine groups as the donor groups were synthesized. The four 4-hexylphenyl groups at the sp -carbon bridges of DHDNP were acquainted with control morphology and improving solubility. The light absorption, energy level, thermal properties, and application as hole-transporting materials in perovskite solar cells of these compounds were fully investigated.

hsa-miR-96 and hsa-miR-217 Expression Down-Regulates with Increasing Dysplasia in Pancreatic Intraepithelial Neoplasias and Intraductal Papillary Mucinous Neoplasms.

To compare the clinicopathological features of pancreatic intraepithelial neoplasias (PanINs) and intraductal papillary mucinous neoplasms (IPMNs), and to investigate the role of hsa-miR-96 and hsa-miR-217 in these two lesions. Formalin-fixed paraffin-embedded pancreatic specimens were selected in this study, including 58 cases of pancreatic intraepithelial neoplasias (PanINs), 45 cases of pancreatic ductal adenocarcinomas (PDAs), and 57 cases of intraductal papillary mucinous neoplasms (IPMNs). MiRNAs hsa-miR-96 and hsa-miR-217 were detected using locked nucleic acid hybridization (LNA-ISH) with the NBT/BCIP staining system.

[Research advances in microRNA in pancreatic ductal adenocarcinoma].

MicroRNA (miRNA), small non-coding RNA consisted of 19-24 nucleotides, are able to regulate gene expression at the post-transcriptional level. The aberrant expressions of miRNA have been found in various cancers and contribute to carcinogenesis by promoting the expression of proto-oncogenes or by inhibiting the expression of tumor suppressor genes. miRNA are related closely with the oncogenesis, progression, and prognosis of tumors.

A case of diffuse panbronchiolitis complicated by peripheral T cell lymphoma not otherwise specified.

We report a case of diffuse panbronchiolitis (DPB) complicated by peripheral T cell lymphoma not otherwise specified. A 40-year-old Chinese man presented with intermittent fever, cough and significant white sputum production for more than 9 years, in addition to dyspnea and chest congestion that worsened after exercise. A chest CT scan indicated diffuse centrilobular fine nodular opacities with a 'tree-in-bud' appearance in both lungs.

[Pathologic study of diffuse pulmonary interstitial fibrosis caused by chronic hypersensitivity pneumonitis].

Objective: To study the pathologic characteristics of chronic hypersensitivity pneumonitis, especially the pattern of pulmonary interstitial fibrosis; and to compare the histologic features with those of idiopathic interstitial pneumonitis.

Methods: The HE-stained paraffin sections of 10 cases of chronic hypersensitivity pneumonitis encountered during the period from 2000 to 2008 were retrospectively analyzed.

Results: There were altogether 6 males and 4 females, with age of patients ranging from 23 to 59 years (mean=47.

[Extranodal Rosai-Dorfman disease].

Objective: To investigate the diagnosis and differential diagnosis of extranodal Rosai-Dorfman disease.

Methods: Two cases of extranodal Rosai-Dorfman disease were studied using hematoxylin-eosin, and immunohistochemical staining, along with a literature review.

Results: The lesions of RDD were characterized by the presence of large histiocytes with emperipolesis, accompanied by infiltration of lymphocytes, plasma cells and other inflammatory cells.
