[Intrauterine Device Totally Embedded in the Bladder Wall:Report of One Case].

Intrauterine device(IUD)migrating to the bladder is rare,especially the migration far away from the uterus into the bladder wall.Due to no obvious clinical symptom in the early stage and being far away from the uterus,the IUD totally embedded in the bladder wall is prone to misdiagnosis and delay in treatment.We reported one case of such migration,aiming to improve the clinical management of the IUD totally embedded in the bladder wall.

[A novel mouse allergy tested model and its application for traditional Chinese medicine injections's allergy evaluation].

When the drug induces the organism to produce a type Ⅰ allergic reaction, the combination of IgE and mast cells results in the degranulation of the mast cells. Release of vasoactive substances, increase in vascular permeability, and exudation of intravascular substances outside the blood vessels. Based on this pathophysiological mechanism, a mouse model that can objectively and quantitatively assess the allergic response to the injection has been established.

Integrative Analysis Identified MCT4 as an Independent Prognostic Factor for Bladder Cancer.

Background: Bladder cancer is the 10th most common cancer and most common urothelial malignancy worldwide. Prognostic biomarkers for bladder cancer patients are required for individualized treatment. Monocarboxylate transporter 4 (MCT4), encoded by gene, is a potential biomarker for bladder cancer because of its crucial role in the lactate efflux in the aerobic glycolysis process.

Sum of High-Risk Gene Mutation (SHGM): A Novel Attempt to Assist Differential Diagnosis for Adrenocortical Carcinoma with Benign Adenoma, Based on Detection of Mutations of Nine Target Genes.

There has been no research on applying gene detection to differential diagnosis of adrenocortical carcinoma (ACC). We attempted to explore a novel auxiliary method for differential diagnosis between ACC with benign adrenocortical adenoma (ACA), based on mutations of target genes in tissues. Nine genes were chosen as target genes, including TP53, CTNNB1, ARMC5, PRKAR1A, ZNRF3, RB1, APC, MEN1, and RPL22.

Cortisol-Producing Adrenal Adenomas With Intense Activity on 68Ga-Pentixafor PET/CT.

CXC chemokine receptor type 4 as a G-protein-coupled receptor has been confirmed to be highly expressed in functional adrenocortical adenomas. 68Ga-pentixafor, a CXC chemokine receptor type 4-specific ligand, has been reported as a promising tracer to evaluate functional nature of adrenal adenomas. We report intense 68Ga-pentixafor activity of cortisol-producing adrenal adenomas in 2 patients with adrenocorticotropic hormone-independent Cushing syndrome.

The purpose of this study was to examine the potential efficacy of TQLB among patients undergoing retroperitoneal procedures, such as the laparoscopic partial nephrectomy (LPN). Methods This prospective, randomized, controlled study was conducted from August 2017 to November 2018 at Peking Union Medical College Hospital (Beijing, China).

Value of Preoperative Neutrophil-to-Lymphocyte Ratio in Predicting Prognosis of Surgically Resectable Urinary Cancers: Systematic Review and Meta-Analysis.

Objective Accumulated evidence has suggested that there is a close association between preoperative neutrophil-to-lymphocyte ratio (NLR) and prognosis of various malignant tumors. However, the relationship between NLR and surgically resectable urinary cancers remains contradictory. Therefore, we performed this systematic review and meta-analysis to explore whether preoperative NLR could predict the prognosis of surgically resectable urinary cancers.

[Research progress of intervention of Chinese herbal medicine and its active components on human coronavirus].

The outbreak caused by 2019 novel coronavirus(2019-nCoV) is still spreading, posing a great threat to the safety and health of general population. However, there have not been any effective drugs for treatment, with symptomatic treatment and prevention prevailing. The treatment plans of severe acute respiratory syndrome(SARS) and Middle East respiratory syndrome(MERS) are often used for reference in clinic.

[Metabonome in Early Diagnosis of Renal Cell Carcinoma].

Renal cell carcinoma(RCC)is one of the most common malignant tumors in the urinary system.Many patients have already been in the advanced stage at the first medical consultation and the prognosis is dismal.Metabonomics searches for differential metabolomes through high-throughput analysis of endogenous metabolites showing high potential in the early diagnosis of RCC and the investigations on its pathophysiological mechanisms.

The Involvement of the RhoA/ROCK Signaling Pathway in Hypersensitivity Reactions Induced by Paclitaxel Injection.

A high incidence of hypersensitivity reactions (HSRs) largely limits the use of paclitaxel injection. Currently, these reactions are considered to be mediated by histamine release and complement activation. However, the evidence is insufficient and the molecular mechanism involved in paclitaxel injection-induced HSRs is still incompletely understood.

[Pharmacokinetic characteristics of fourteen main components of Gegen Qinlian Decoction in rats].

Animal traditional Chinese medicine has a long history of application in China, and its clinical application is very extensive. Due to the complex chemical composition in animal traditional Chinese medicine, the basis of chemical research is relatively weak, which leads to the unclear composition and toxic components of many animal Chinese medicines. The relationship between the medicinal and toxic components of animal Chinese medicine has not yet been elucidated.

[Safety of animal traditional Chinese medicine (TCM) injections].

Animal medicine injection is an important part of traditional Chinese medicine (TCM) injections. All or part of animals with a significant curative effect and little side reactions as raw materials as well as modern technology are used to produce traditional Chinese medicine injections with a reliable and rapid drug efficacy and high bioavailability. Due to the complex composition of traditional Chinese medicine injections, imperfect quality standards, and unreasonable clinical use, the incidence of adverse reactions of traditional Chinese medicine injections has been significantly higher than that of traditional Chinese medicine for oral use.

Research Advances and Prospects on Mechanism of Sinomenin on Histamine Release and the Binding to Histamine Receptors.

Sinomenine (SIN) is widely used in China to treat a variety of rheumatic diseases (RA), and has various pharmacological effects such as anti-inflammatory, analgesic, and anti-tumor effects. However, due to the histamine release characteristics of SIN, its adverse reactions such as allergic reactions, gastrointestinal reactions, and circulatory systemic reactions have been drawing increasing attention. We present here a systematic review of the chemical structure, pharmacological effects, clinical application, and adverse reactions of SIN, a detailed discussion on the relationship between histamine/histamine receptor and mechanism of action of SIN.

Is Prophylactic Steroid Treatment Mandatory for Subclinical Cushing Syndrome After Unilateral Laparoscopic Adrenalectomy?

Objective: This study aimed to provide rational guidelines for patients with subclinical Cushing syndrome (SCS), who are undergoing laparoscopic adrenalectomy, in order to avoid the risk of overtreatment.

Methods: A total of 59 patients diagnosed with SCS caused by unilateral adrenal adenoma, who underwent laparoscopic adrenalectomy from 2010 to 2017, were included into the study. These patients did not receive prophylactic steroid treatment.

[Preclinical study on adverse reactions of Xingnaojing injection].

In this study, different batches of Xingnaojing injection products were first selected for pseudoallergic mice test, and the results showed that after injection of 6.6-fold clinical dose Xingnaojing injection, the mice showed a slight pseudoallergic reaction, while other mice injected with other batches of injections showed no obvious pseudoallergic reaction. Therefore, it is preliminarily believed that this mice model can effectively indicate the risk of pseudoallergic reactions in the clinical application of Xingnaojing injections.
