Benign Phyllodes Tumors: Comparison of Prognosis among Three Different Surgical Approaches.

Purpose: To evaluate the prognosis of patients with benign phyllodes tumors (PTs) treated by different surgical methods and to explore the influencing factors of local recurrence.

Methods: We retrospectively analyzed 215 benign PTs from 193 patients who underwent surgery at Chinese PLA General Hospital between October 2008 and December 2020. We stratified our analysis according to surgical factors and explored the clinicopathological factors to influence local recurrence.

The significance of galactose-deficient immunoglobulin A1 staining in kidney diseases with IgA deposition.

Background: This study investigated the significance of galactose-deficient immunoglobulin A1 staining in kidney diseases with IgA deposition.

Methods: A total of 120 patients with IgA-dominant deposition in kidney tissues were enrolled and divided into four groups: primary IgA nephropathy (PIgAN), secondary IgA nephropathy (SIgAN), monotypic IgA nephropathy (MIgAN), and IgA variant monoclonal gammopathy of renal significance (IgA-MGRS). KM55 (the antibody of galactose-deficient immunoglobulin A1), IgA subtypes, and complement pathway factors (properdin, C4d, and C1q) were detected through immunofluorescence or immunohistochemistry analysis.

Collagen fiber features and COL1A1: are they associated with elastic parameters in breast lesions, and can COL1A1 predict axillary lymph node metastasis?

Background: This study aimed to explore whether collagen fiber features and collagen type I alpha 1 (COL1A1) are related to the stiffness of breast lesions and whether COL1A1 can predict axillary lymph node metastasis (LNM).

Methods: Ninety-four patients with breast lesions were consecutively enrolled in the study. Amongst the 94 lesions, 30 were benign, and 64 were malignant (25 were accompanied by axillary lymph node metastasis).

Coronaviruses in wild animals sampled in and around Wuhan at the beginning of COVID-19 emergence.

Over the last several decades, no emerging virus has had a profound impact on the world as the SARS-CoV-2 that emerged at the end of 2019 has done. To know where severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originated from and how it jumped into human population, we immediately started a surveillance investigation in wild mammals in and around Wuhan when we determined the agent. Herein, coronaviruses were screened in the lung, liver, and intestinal tissue samples from fifteen raccoon dogs, seven Siberian weasels, three hog badgers, and three Reeves's muntjacs collected in Wuhan and 334 bats collected around Wuhan.

[Laparoscopic Common Bile Duct Exploration for Treatment of Common Bile Duct Stones:Clinical Analysis of 158 Cases].

Objective To evaluate the safety and effectiveness of laparoscopic common bile duct exploration in the treatment of common bile duct stones. Methods A retrospective analysis was conducted for 158 patients with cholecystolithiasis and choledocholithiasis admitted to the Number One Hospital of Zhangjiakou from January 2015 to December 2019.The patients were assigned into three groups according to the diameters of cystic duct and common bile duct,degrees of abdominal infection and tissue edema,and operation method.

A new coronavirus associated with human respiratory disease in China.

Emerging infectious diseases, such as severe acute respiratory syndrome (SARS) and Zika virus disease, present a major threat to public health. Despite intense research efforts, how, when and where new diseases appear are still a source of considerable uncertainty. A severe respiratory disease was recently reported in Wuhan, Hubei province, China.

In-situ establishment of binary composites α-FeO/BiOCl with both photocatalytic and photo-Fenton features.

A set of binary composites α-FeO/BiOCl were established through an in-situ deposition route and these samples were systematically characterized by a collection of analytical techniques. Scanning electron microscopy, UV-vis diffuse reflectance spectroscopy, and X-ray photoelectron spectroscopy proved the coexistence of expected two components. High resolution transmission electron microscopy and selected-area electron diffraction indicated the formation of heterojunction domains with the intimate contact of both semiconductors.

Common genetic variant on 14q13.3 contributes to thyroid cancer susceptibility: evidence based on 12 studies.

Several genome-wide association studies on thyroid cancer (TC) have reported similar findings of a new susceptibility locus, 14q13.3. After that, a number of studies reported that rs944289 polymorphism at chromosome 14q13.
