miRNAs from Plasma Extracellular Vesicles Are Signatory Noninvasive Prognostic Biomarkers against Atherosclerosis in LDLrMice.

Circular microRNAs (miRNAs) have become central in pathophysiological conditions of atherosclerosis (AS). However, the biomarkers for diagnosis and therapeutics against AS are still unclear. The atherosclerosis models in low-density lipoprotein receptor deficiency (LDLr) mice were established with a high-fat diet (HFD).

Revealing the Synergistic Mechanism of Multiple Components in Compound Fengshiding Capsule for Rheumatoid Arthritis Therapeutics by Network Pharmacology.

Background: Compound Fengshiding capsule (CFC), is a Chinese formulation from herbal origin including Alangium platanifolium, Angelicae dahurica, Cynanchum paniculatum and Glycyrrhiza uralensis. CFC is widely used as clinical therapy against rheumatoid arthritis. However, its exact mechanism of action has not been explored yet.

Efficacy, safety and influencing factors of intra-calf muscular injection of bone marrow mononuclear cells in the treatment of type 2 diabetes mellitus-induced lower extremity vascular disease.

The efficacy, safety and impact of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) associated with the intra-calf muscular injection of bone marrow mononuclear cells (BMMCs) in the treatment of type 2 diabetes mellitus (T2DM)-induced lower extremity vascular disease (LEVD) were evaluated. Patients with T2DM-LEVD were randomly divided into a control group and BMMCs group to assess the efficacy and safety of the treatment; serum VEGF and bFGF levels were detected. The BMMCs group was divided into superior genicular artery (SGA) and inferior genicular artery (IGA) subgroups as well as low-dose and high-dose subgroups for the comparison of efficacy indices.

Differences and Similarities in the Clinicopathological Features of Pancreatic Neuroendocrine Tumors in China and the United States: A Multicenter Study.

The presentation, pathology, and prognosis of pancreatic neuroendocrine tumors (PNETs) in Asian patients have not been studied in large cohorts. We hypothesized that the clinicopathological features of PNETs of Chinese patients might be different from those of US patients. The objectives of this study were to address whether PNETs in Chinese patients exhibit unique clinicopathological features and natural history, and can be graded and staged using the WHO/ENETS criteria.

α-Internexin: a novel biomarker for pancreatic neuroendocrine tumor aggressiveness.

Purpose: We aimed to test whether α-internexin could be a molecular biomarker of tumor aggressiveness and prognosis in pancreatic neuroendocrine tumors (PNETs).

Patients And Methods: Using immunohistochemical staining and Western blot, we detected the expression of α-internexin in 350 tumors from 343 patients, of whom 257 were followed up. Methylation of α-internexin promoter was examined by bisulfite sequencing to identify the crucial region that determines gene expression.

Bilateral pheochromocytoma as first presentation of von Hippel-Lindau disease in a Chinese family.

Objective: To investigate the clinical and genetic features of a Chinese family with von Hippel-Lindau (VHL) disease revealed by bilateral pheochromocytoma.

Methods: The proband and other members in a Chinese family with familial pheochromocytoma were clinically evaluated and followed up. Genomic DNA extracted from the peripheral blood of 8 family members (including 3 patients) was amplified by polymerase chain reaction (PCR) and the PCR products were directly sequenced.

[Expression of renin-angiotensin-aldosterone system in human adipose tissues].

Objective: To compare the mRNA expression of renin-angiotensin-aldosterone system in human subcutaneous and visceral adipose tissues.

Methods: Total RNA was extracted from 12 human subcutaneous adipose tissues, 12 perirenal adipose tissue and 9 periadrenal adipose tissues. The expressions of angiotensinogen ( AGT) , renin, angiotensin converting enzyme ( ACE) , angiotensin converting enzyme 2 (ACE2), angiotensin I1 receptor type 1 (AT1), angiotensin II receptor type 2 (AT2 ), CYP11 B2, and their internal reference glyceraldehyde phosphate (GAPDH) were studied by reverse transcription-polymerase chain reaction.

[Effect of hypokalemia on glucose metabolism in primary hyperaldosteronism].

Objective: To investigate the effect of potassium deficiency on glucose and insulin metabolism in primary hyperaldosteronism, including aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA).

Methods: Totally 178 patients who were diagnosed as primary hyperaldosteronism (103 patients with APA and 75 with IHA) were divided into hypokalemia group and normal potassium group according to their serum potassium levels. All patients received 3 hours of oral glucose tolerance test and aldosterone test to observe the relationship among glucose, insulin and serum potassium.

von Hippel-Lindau gene mutation in non-syndromic familial pheochromocytomas.

Approximately 50% of patients with non-syndromic familial pheochromocytomas had germline von Hippel-Lindau (VHL) gene mutations, but no reports on the subject were available in China. A total of five unrelated Chinese families with non-syndromic familial pheochromocytomas were screened for VHL gene mutation by polymerase chain reaction (PCR) and subsequent direct sequencing. Missense germline mutations of VHL gene were detected in four of the five families.
