MiR-214-3p Prevents the Development of Perioperative Neurocognitive Disorders in Elderly Rats.

Objective: This study aimed to identify microRNAs (miRNAs) involved in the development of perioperative neurocognitive disorders (PND).

Methods: Plasma exosomal miRNA expression was examined in patients before and after cardiopulmonary bypass (CPB) using microarray and qRT-PCR and these patients were diagnosed as PND later. Elderly rats were subjected to CPB, and the cognitive functions were examined.

[Study on Behavioral Factors Affecting the Risk of New HBV Infection among Diabetic Patients].

Objective: To analyze the behavioral factors influencing of new hepatitis B virus (HBV) infection in diabetic patients, so as to provide evidence for reducing the risk of new HBV infection in diabetic patients.

Methods: A nested case-control study was conducted to follow up and observe 4 586 diabetic patients. The 114 diabetic patients who newly developed HBV infection during the follow-up period were selected as the case group, and 228 diabetic patients who did not develop HBV infection in the same period were selected as the control group from the cohort population at a matching ratio of 1∶2 according to the age ±2 years.

Expression Patterns of Three Important Hormone Genes and Respiratory Metabolism in during Pupal Diapause under a Long Photoperiod.

The Chinese oak silkworm is commonly used in pupal diapause research. In this study, a long photoperiod was used to trigger pupal diapause termination. Genes encoding three hormones, namely prothoracicotropic hormone (PTTH), ecdysis triggering hormone (ETH), and eclosion hormone (EH), were studied.

[Associations between Takeaway Food Nutrients and Nutritional Literacy of Takeaway Platform Practitioners in Chengdu].

Objective To investigate the nutritional literacy levels of the takeaway platform practitioners in Chengdu,the takeaway food nutrients,and the correlation between them.Methods We employed a multi-stage random sampling method to investigate the nutritional literacy levels of 100 takeaway platform restaurants in the main urban area of Chengdu and examined the nutritional components of hot set meals in each restaurant.A questionnaire survey was conducted on the nutritional literacy levels of chefs and food matching staff.

[Nutritional Knowledge and Skills of Fast-food Takeout Practitioners in Chengdu City].

Objective To investigate the current status of nutritional knowledge and skills of fast-food takeout practitioners in Chengdu City,so as to provide evidence for nutritional literacy education among takeout practitioners.Methods A questionnaire survey was conducted among 832 employees of fast-food takeout restaurants in Chengdu from April to September in 2019 through a multi-stage random sampling strategy.Results The awareness rate of nutritional knowledge of fast-food takeout practitioners in Chengdu was 77.

Prefrontal cortex miR-29b-3p plays a key role in the antidepressant-like effect of ketamine in rats.

Ketamine has a rapid, obvious, and persistent antidepressant effect, but its underlying molecular mechanisms remain unknown. Recently, microRNAs (miRNAs) have emerged as important modulators of ketamine's antidepressant effect. We investigated the alteration in miR-29b-3p in the brain of rats subjected to ketamine administration and chronic unpredictable mild stress (CUMS), and a sucrose preference test and forced swimming test were used to evaluate the rats' depressive-like state.

Elevated Serum and Cerebrospinal Fluid Free Fatty Acid Levels Are Associated with Unfavorable Functional Outcome in Subjects with Acute Ischemic Stroke.

The aim of this study was to evaluate the prognostic value of serum and cerebrospinal fluid (CSF) free fatty acid (FFA) levels in a cohort of patients with an acute ischemic stroke (AIS). In a prospective study, FFA levels were measured using an enzyme cycling method on admission in serum and CSF of 252 consecutive patients with AIS. The prognostic value of FFA to predict the functional outcome and mortality within 90-day was compared with the National Institutes of Health Stroke Scale score and with other known outcome predictors.

The diagnostic and prognostic value of serum CXCL12 levels in patients with ischemic stroke.

The aim of this study was to investigate the potential diagnostic and prognostic role of CXC chemokine ligand-12 (CXCL12) in Chinese patients with acute ischemic stroke (AIS). All consecutive patients with first-ever AIS from January 2014 to August 2014 were recruited to participate in the study. CXCL12 and NIH Stroke Scale were measured at the time of admission.

[Changes in cardiac specific microRNA-208a level in peripheral blood in ST segment elevation acute myocardial infarction patients].

Objective: To observe serum cardiac specific microRNA-208a (miR-208a) levels in ST segment elevation acute myocardial infarction (STEAMI) patients, and to explore the role of serum miR-208a levels in the diagnosis of STEAMI.

Methods: The serum miR-208a concentrations were assessed within 12 hours after STEAMI, while 30 healthy individuals as control. Serum miR-208a concentrations were measured with real-time quantity reverse transcription-polymerase chain reaction (qRT-PCR), and serum cardiac troponin I (cTnI) or MB isoenzyme of creatine kinase (CK-MB) concentrations were measured with enzyme linked immunosorbent assay (ELISA).

[Urine cardiac specific microRNA-1 level in patients with ST segment elevation acute myocardial infarction].

Objective: To observe the change of urine level of cardiac specific microRNA-1 (miR-1) in patients with ST segment elevation acute myocardial infarction (STEAMI) and investigate its potential applications.

Methods: Urine samples were collected from 20 STEAMI patients within 12 hours after STEAMI and from 20 healthy volunteers as control. Urine miR-1 concentrations were measured with real-time quantity reverse transcription-polymerase chain reaction (qRT-PCR), at the same time serum cardiac troponin I (cTnI) and MB isoenzyme of creatine kinase (CK-MB) concentrations were measured.

[Electrooptical properties of nanoscale and bulk SrAl2O4: Eu, Dy].

Nanoscale and bulk SrAl2O4 : Eu2+, Dy3+ were prepared respectively by auto-combustion of citrate gelatin and high temperature solid state method. The crystalline structure was examined by X-ray diffraction (XRD). The current-voltage characteristic was measured with a Keithley source meter 2 410.

[Investigations on the movement of pigment particles in the electrophoretic liquids].

In the present report, the authors studied the movement of pigment particles which decide the display status, enduced the equation of the motion and the expression of reflectivity, and estimated the value of the delay time. Combining the above theoretical conclusion with the experimental results, the authors discussed the feasibility of the passive matrix addressing of electrophoretic image displays, and provided good advice on how to acquire display devices of good quality.
