[The new progress and significance of new ultrasound technology in the diagnosis of azoospermia].

The diagnosis and treatment of azoospermia rely heavily on auxiliary ex-amination technology. Compared with CT and MRI, ultrasound has more practical value in the diagnosis of azoospermia.Currently, the main ultrasonic technologies are contrast-enhanced ultrasound, real-time ultrasound elastography and ultrasound tar-geted puncture.

Predictive value of left ventricular dyssynchrony for short-term outcomes in three-vessel disease patients undergoing coronary artery bypass grafting with preserved or mildly reduced left ventricular ejection fraction.

Background And Objective: Coronary artery bypass grafting (CABG) is the reference standard intervention in coronary artery disease (CAD) patients with three-vessel disease (3VD). We aimed to evaluate the predictive value of left ventricular (LV) dyssynchrony for short-term adverse outcomes in patients with 3VD undergoing CABG with preserved or mildly reduced LV ejection fraction (LVEF).

Materials And Methods: This study involved ninety-five 3VD patients with preserved or mildly reduced LVEF undergoing scheduled on-pump CABG.

Effect of intraoperative dexmedetomidine on hepatic ischemia-reperfusion injury in pediatric living-related liver transplantation: A propensity score matching analysis.

Background: Hepatic ischemia-reperfusion injury (HIRI) is largely unavoidable during liver transplantation (LT). Dexmedetomidine (DEX), an 2-adrenergic agonist, exerts a variety of organ-protective effects in pediatric populations. However, evidence remains relatively limited about its hepatoprotective effects in pediatric living-related LT.

Intraoperative Low-Dose Dexmedetomidine Administration Associated with Reduced Hepatic Ischemia-Reperfusion Injury in Pediatric Deceased Liver Transplantation: A Retrospective Cohort Study.

BACKGROUND Dexmedetomidine (DEX) attenuates hepatic ischemia-reperfusion injury (HIRI) in adult liver transplantation (LT), but its effects on postoperative liver graft function in pediatric LT remain unclear. We sought to investigate whether intraoperative DEX administration was associated with improved liver graft function in pediatric LT recipients. It was hypothesized that DEX administration was associated with reduced HIRI and improved liver graft function.

Assessment of Myocardial Dysfunction by Three-Dimensional Echocardiography Combined With Myocardial Contrast Echocardiography in Type 2 Diabetes Mellitus.

We aimed to explore the value of combining real-time three-dimensional echocardiography (RT-3DE) and myocardial contrast echocardiography (MCE) in the left ventricle (LV) evaluating myocardial dysfunction in type 2 diabetes mellitus (T2DM) patients. A total of 58 T2DM patients and 32 healthy individuals were selected for this study. T2DM patients were further divided into T2DM without microvascular complications ( = 29) and T2DM with microvascular complications ( = 29) subgroups.

Case Presentation: A 51-year-old woman was admitted to our hospital complaining of chest tightness, palpitations and dyspnoea after activity.

SUBCLINICAL IMPAIRMENT OF LEFT VENTRICULAR LONGITUDINAL FUNCTION IN PATIENTS WITH PROLACTINOMAS.

Objective: Hyperprolactinemia has been associated with endothelial dysfunction and a wide range of cardiovascular risk factors, thus it can potentially lead to cardiac dysfunction. The present study was designed to interrogate our hypothesis that hyperprolactinemia can contribute to preclinical impaired left ventricular function.

Methods: Thirty-one prolactinoma patients and 60 healthy volunteers were prospectively recruited.

Encodes a Glutaminase in Vitamin B Biosynthesis Essential for Maize Seed Development.

Vitamin B, an essential cofactor for a range of biochemical reactions and a potent antioxidant, plays important roles in plant growth, development, and stress tolerance. Vitamin B deficiency causes embryo lethality in Arabidopsis (), but the specific role of vitamin B biosynthesis in endosperm development has not been fully addressed, especially in monocot crops, where endosperm constitutes the major portion of the grain. Through molecular characterization of a () mutant in maize, we reveal that vitamin B has differential effects on embryogenesis and endosperm development in maize.

Unraveling molecular effects of ADAR1 overexpression in HEK293T cells by label-free quantitative proteomics.

ADAR1 is a double-stranded RNA (dsRNA) editing enzyme that specifically converts adenosine to inosine. ADAR1 is ubiquitously expressed in eukaryotes and participate in various cellular processes such as differentiation, proliferation and immune responses. We report here a new proteomics study of HEK293T cells with and without ADAR1 overexpression.

Efficacy and safety of low-dose clopidogrel after 12-month dual antiplatelet therapy for patients having drug-eluting stent implantation.

Background: To prevent stent thrombosis (ST) after implantation of drug-eluting stents (DESs) in patients with coronary heart disease, 12-month dual antiplatelet therapy (DAPT) is recommended. However, the optimal long-term antiplatelet regimen is not clear for the patients who have completed the 12-month DAPT.

[Updated immunoregulation mechanism of the testis].

The testis is an immune privileged organ where germ cells are protected from autoimmune attack to ensure its reproductive function. Immune tolerance is important for the normal development and function of the testis. Notwithstanding its immune-privileged status, the imbalance between the tolerogenic and the efferent limb of the testicular immune response may lead to autoimmune damage in inflammatory or infected circumstances.

Increased carotid intima media thickness is associated with prolactin levels in subjects with untreated prolactinoma: a pilot study.

Hyperprolactinemia is associated with endothelial dysfunction and atherogenic risk factors, but carotid intima media thickness (IMT) has not been studied in hyperprolactinemic patients. To determine whether untreated hyperprolactinemia contributes to increased carotid IMT. Thirty-one prolactinoma patients and 60 healthy controls were respectively studied.
