Notes

Ultra-narrowband resounding mild absorber for high-performance thermal-optical modulators.
The duration of the treatment will be 1 month and a follow-up for 11 months. The primary outcome will be the number of acute exacerbation episodes of COPD, and the secondary outcomes will include the lung function, St George's Respiratory Questionnaire, COPD Assessment Test, and 6-Minute Walk Test. A safety assessment will also be performed during the trial. DISCUSSION The aim of this study is to evaluate the efficacy and safety of TCM acupoint application in preventing acute exacerbation of stable COPD. Our study will provide sound evidence to support the evidence-based medicine of TCM acupoint application as an additional measure in the prevention of acute exacerbation of stable COPD. TRIAL REGISTRATION ChiCTR1900026564, Registered 14 October, 2019.INTRODUCTION Patients with chronic pulmonary obstructive disease (COPD) are at risk of acute exacerbation. Diaphragm muscle is classically highly solicited in COPD exacerbation. PATIENT CONCERNS A COPD patient was admitted because of acute dyspnea with wheezing. DIAGNOSIS acute COPD exacerbation. INTERVENTIONS A diaphragm ultrasound and a Doppler echocardiography were performed at bedside. OUTCOMES We measured diaphragm thickening at the apposition zone and diaphragm inspiratory motion from the subcostal view, in addition with classical echocardiographic parameters. CONCLUSION Despite a normal diaphragm thickening, diaphragm motion during inspiration is reduced in acute COPD exacerbation. These apparently discrepant findings may be explained by the alterations of the respiratory mechanics during COPD exacerbations, which should be considered when evaluating the diaphragmatic function by imaging.BACKGROUND Type 2 diabetes (T2D) is a risk factor for cognitive dysfunction. The relationship between metformin therapy and cognitive function in patients with T2D is unknown. Therefore, we determined the relationship between metformin therapy and cognitive function in patients with T2D using a meta-analysis. METHODS We systematically searched the Cochrane library, PubMed, and Embase to identify studies showing correlations, and we calculated hazard ratios (HRs). RESULTS We identified 10 studies including 254,679 participants. Metformin significantly reduced the occurrence of cognitive dysfunction in patients with T2D (HR 0.90; 95% CI [0.88, 0.92]). Compared with other hypoglycemic drugs, sulfonylureas also improved cognitive dysfunction (HR 0.92; 95% CI [0.88, 0.95]). Thiazolidinediones gave no statistically significant improvement in cognitive dysfunction (HR 0.97; 95% CI [0.87, 1.07]). The use of insulin aggravated cognitive dysfunction (HR 1.34; 95% CI [1.24, 1.43]). In the subgroup analysis of various regions controlling for age, gender, education, diabetes course, complications, metformin administration and dosage, and follow-up time, metformin significantly improved cognitive dysfunction in patients in the Americas and Europe (HR 0.69; 95% CI [0.63, 0.74]), (HR 0.71; 95% CI [0.66, 0.76], respectively), while metformin did not significantly improve cognitive dysfunction in Asian patients (HR 0.99; 95% CI [0.96, 1.01]). CONCLUSIONS Metformin significantly improved cognitive dysfunction in patients with T2D. Sulfonylureas also improved cognitive dysfunction. Thiazolidinediones had no significant effect on cognitive dysfunction. The use of insulin aggravated cognitive dysfunction. Metformin improved cognitive dysfunction more significantly in patients in the Americas and Europe than in Asia.BACKGROUND Perimenopause is a period that every woman must go through, most people are more or less affected by perimenopausal symptoms, it to affect women's health, work, life, and economy. As acupuncture treatment is more and more increasing in perimenopausal symptoms, there have also been many clinical trials about it. But the results of the trials are inconsistent. Therefore, we will conduct a systematic review and meta-analysis of the safety and efficacy of perimenopausal symptoms treated with acupuncture. METHODS The protocol followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. RCT study on different acupuncture interventions for perimenopausal symptoms will be searched in 8 databases (PubMed, EMBASE, the Cochrane Library, the web of science, CBM, CNKI, WAN FANG, and VIP). PF-06424439 Besides, the search will also be performed on the clinical trial research platform if necessary. The primary outcome that will be extracted the Flushes per 24 hours, the Frequency of hot flashes, the treat perimenopausal symptoms and better design of control groups in related clinical trials. In addition, the research conclusion will be published in peer journals.OSF REGISTRATION NUMBER DOI 10.17605/OSF.IO/VZCKU Ethics and dissemination This conclusion of the study will be published in peer journals. The ethical approval is not required because there is no direct involvement of human.OBJECTIVES Preptin, irisin and adropin are 3 new players in energy regulation that are related body mass index, lipids, glucose and insulin levels which may affect incidence of cardiovascular diseases. The aim of the present study was to evaluate eight single nucleotide polymorphisms (SNPs) of preptin genes (rs1003483, rs1004446, rs2239681, rs680, and rs3741204), irisin (rs16835198 and rs3480) and adropin (rs2281997) gene in patients with coronary artery disease (CAD) and hypertension. METHODS This case-control study was carried out on 372 volunteers, which were divided into 3 subgroups including CAD patients with hypertension (CAD+H+), CAD patients with no hypertension (CAD+H-), and non-hypertensive non-CAD subjects as control group (CAD-H-) as health control. Genomic DNA from whole blood was extracted and eight SNPs were assessed using polymerase chain reaction- ligase detection reaction method. RESULTS A significant difference was found in the genotype and allele frequency of preptin rs1003483 gene in CAD+H+ compared to CAD+H- groups (P = .019 and P = .018, respectively). Allele frequency of rs1003483 was significantly different between CAD+H- groups and healthy control groups (P = .043). There also existed a significant difference the genotype frequency of rs1004446 gene in CAD+H+ compared to CAD+H- groups (P = .027). CONCLUSIONS The findings of present study revealed that the preptin rs1003483 and rs1004446 gene polymorphism might serve as predisposing factor in CAD and hypertension.
