Targeted Next-Generation Sequencing for the Diagnosis of Gene Variants in Patients with 46,XY Disorder of Sex Development.

Introduction: Disorders of sex development (DSDs) are congenital abnormalities in which chromosomal, gonadal, and anatomical sex development are atypical. One of these disorders, 46,XY DSD, is particularly difficult to diagnose and manage because its etiology and clinical phenotypes are highly heterogeneous.

Methods: We used a gene panel containing 141 genes implicated in DSDs to perform targeted next-generation sequencing (NGS) in 50 patients with 46,XY DSD.

Grim-19 plays a key role in mitochondrial steroidogenic acute regulatory protein stability and ligand-binding properties in Leydig cells.

Grim-19 (gene associated with retinoid-IFN-induced mortality 19), the essential component of complex I of mitochondrial respiratory chain, functions as a noncanonical tumor suppressor by controlling apoptosis and energy metabolism. However, additional biological actions of Grim-19 have been recently suggested in male reproduction. We investigated here the expression and functional role of Grim-19 in murine testis.

Intravenous injections of the oncolytic virus M1 as a novel therapy for muscle-invasive bladder cancer.

Muscle-invasive bladder cancer (MIBC) is associated with low survival and high recurrence rates even in cases in which patients receive systemic treatments, such as surgery and chemotherapy. Here, we found that a naturally existing alphavirus, namely, M1, selectively kills bladder cancer cells but not normal cells, findings supported by our observations of changes in viral replication and MIBC and patient-derived MIBC cell apoptosis. Transcriptome analysis revealed that interferon-stimulated genes (ISGs) are expressed at low levels in sensitive bladder cancer cells and high levels in resistant cells.

Gold-chrysophanol nanoparticles suppress human prostate cancer progression through inactivating AKT expression and inducing apoptosis and ROS generation in vitro and in vivo.

Controlled releasing of regulations remains the most convenient method to deliver various drugs. In the present study, we precipitated gold nanoparticles with chrysophanol. The gold-chrysophanol into poly (DL-lactide-co-glycolide) nanoparticles was loaded and the biological activity of chrysophanol nanoparticles on human LNCap prostate cancer cells, was tested to acquire the sustained releasing property.

Sesquiterpenoids from the twigs and leaves of Fokienia hodginsii.

A rare carotane-type sesquiterpenoid, forkienin A (1), a new eudesmane-type sesquiterpenoid, forkienin B (2), and a new natural eudesmane-type sesquiterpenoid, forkienin C (3), were isolated from the twigs and leaves of Fokienia hodginsii, along with eight known sesquiterpenoids. The structures of the new compounds were elucidated on the basis of their spectroscopic analysis, including 1D and 2D NMR methods. All compounds were evaluated for cytotoxicity against HL-60, SMMC-7721, A-549, MCF-7, and SW480 cell lines.

[Clinical significance of ID4 methylation detection by quantitative methylation-specific PCR in acute leukemia].

The advances of treatment improved the prognosis of the patients with acute leukemia (AL) in the last decade, but the lack of general biomarker for predicting relapse in AL, which is one of the most important factors influencing the survival and prognosis. DNA methylation of ID4 gene promoter occurred frequently in patients with AL and was found to be highly related to the tumor progression. Based on the previous work of the setup of methylation-specific quantitative PCR system for ID4 gene, this study was designed to investigate the relation between the quantitative indicator of methylation density, percentage of methylation reference(PMR) value, and different disease status of AL.

[Efficacy and safety analysis of interferon combined with imatinib in treating chronic myeloid leukemia].

Imatinib has been recognized as the frontline therapy drug in chronic myeloid leukemia (CML), however, only limited patients could achieve complete molecular remission (CMR). Recent clinical and basic proofs indicated an improved treatment outcome by the combination of interferon and Imatinib. This study was purposed to evaluated systematically the efficacy and safety of interferon plus Imatinib in patients with CML.

Insulin resistance correlates with the arterial stiffness before glucose intolerance.

Objective: The elevated plasma glucose level and/or insulin resistance in diabetes or impaired glucose tolerance play important roles in the pathogenesis of arterial stiffness. The present study investigated whether insulin resistance correlated with arterial stiffness before the development of glucose intolerance.

Methods: We conducted a cross-sectional analysis in 872 young to middle-age individuals with normal glucose tolerance (aged 36.

[Different prevalence of impaired glucose tolerance between hyperinsulinemic and normoinsulinemic subjects].

Objective: To study the impact of different insulin levels on the conversion from impaired glucose tolerance (IGT) to type 2 diabetes mellitus (T2DM), through analysis of different glycometabolism condition among quinquagenarian population.

Methods: Subjects enrolled were Beijing habitants who received annual physical examination [including oral glucose tolerance test (OGTT)] in the Chinese PLA General Hospital from 2005 - 2007. According to the OGTT results, the subjects were divided into three groups, including normal glucose tolerance-non-hyperinsulinemia group (NGT-NHIns), IGT-hyperinsulinemia group (IGT-HIns) and IGT-non-hyperinsulinemia group (IGT-NHINS).

Laparoscope resection of ectopic corticosteroid-secreting adrenal adenoma.

Tumors originating from ectopic adrenal tissue are relatively rare. In this article, we describe a case with Cushing's syndrome caused by an ectopic adrenal adenoma. A 38 year-old male patient presenting with cushingoid appearance for 2 years was diagnosed to have ACTH-independent Cushing's syndrome based on endocrinological evaluation.

Spontaneous remission of acromegaly or gigantism due to subclinical apoplexy of pituitary growth hormone adenoma.

Background: Subclinical apoplexy of pituitary functional adenoma can cause spontaneous remission of hormone hypersecretion. The typical presence of pituitary growth hormone (GH) adenoma is gigantism and/or acromegaly. We investigated the clinical characteristics of patients with spontaneous partial remission of acromegaly or gigantism due to subclinical apoplexy of GH adenoma.

Chronic inflammatory demyelinating polyneuropathy mimicking diabetic neuropathy in a young female with type 2 diabetes mellitus.

The presentations of chronic inflammatory demyelinating polyneuropathy (CIDP) overlap with those of diabetic peripheral neuropathy (DPN). We described a young girl with CIDP underlying type 2 diabetes mellitus, presenting with progressive numbness and limb weakness, who was initially misdiagnosed to have DPN. Finally immunosuppressive therapy got good response.
