Rehabilitation Effects of Acupuncture on the Diaphragm Dysfunction in Chronic Obstructive Pulmonary Disease: A Systematic Review

Introduction Diaphragm dysfunction is a significant extrapulmonary effect in chronic obstructive pulmonary disease (COPD), which is manifested by changes in diaphragm structure and reduced diaphragm strength. Acupuncture is a traditional rehabilitation technique in China, which has been used in rehabilitation for COPD. But whether acupuncture can improve the diaphragm function of COPD patients remains to be verified. Objective The objective of this study was to evaluate the rehabilitation effects of acupuncture on diaphragm dysfunction in patients with COPD. Methods The authors retrieved in CNKI, VIP, SinoMed, PubMed, Ebsco, Web of Science, from inception to November 2020, for relevant randomized control trials. Two researchers independently screened the articles and extracted the data. The quality of the included studies was evaluated by Physiotherapy Evidence Database scale. The primary outcome measures were maximal inspiratory pressure and the scale for accessory respiratory muscle mobilization, the secondary outcome measures were pulmonary function-related indicators and arterial blood gas indicators. Results Nine articles were finally obtained. Seven studies added acupuncture to standard treatment for patients with diaphragm dysfunction in COPD and found statistically significant changes in the maximum inspiratory pressure and the scale for accessory respiratory muscle mobilization. Two studies have proved that use acupuncture combined with other Traditional Chinese Medicine methods in the rehabilitation for COPD can effectively improve the diaphragm strength and diaphragmatic motor performance. Seven studies showed that acupuncture has obvious improvement in pulmonary ventilation function. Seven studies reported significant differences in arterial blood gas pre- to post-intervention. Conclusion This systematic review found that acupuncture can effectively enhance the diaphragm strength, relieve respiratory muscle fatigue, it can also play a promoting role in improving lung function, hypoxia, and carbon dioxide retention, as well as preventing and alleviating respiratory failure. The generalizability of these results is limited by the design of the included studies.
Ameliorative impacts of Glycyrrhiza glabra root extract against nephrotoxicity induced by gentamicin in mice

Abstract Gentamicin is an effective antibiotic that has been used worldwide for many years. While considered an essential medicine by the WHO, gentamicin can also lead to severe kidney damage. This study explored the ameliorative effects of Glycyrrhiza glabra root extract on gentamicin‐induced renal injury in mice. Four groups of n = 7 mice were used: (a) control; (b) G. glabra‐only; (c) gentamicin‐only; and (d) gentamicin plus G. glabra. Kidney samples were tested for: antioxidant enzyme activity (superoxide dismutase [SOD] and glutathione peroxidase [Gpx]); expression of HO‐1 and nuclear factor erythroid 2‐related factor 2 genes; expression of Cox‐2 and Bax; cytokine levels (IL‐1β, and IL‐6); histopathological anomalies; and standard renal functional component levels (creatinine, urea, and blood urea nitrogen). The effects of gentamicin were generally reversed or normalized following treatment with G. glabra root extract. Gentamicin decreased Gpx and SOD parameters and increased IL‐1 β and IL‐6 levels, but these returned to normal in the G. glabra‐treated group. Gentamicin upregulated tissue levels of Cox‐2 and Bax, and downregulated HO‐1 and Nrf‐2 expression but again, and these levels returned to normal in the group treated with G. glabra. Mice that had received gentamicin exhibited acute renal blood vessel congestion, focal interstitial round cell aggregation, and hydropic degeneration of renal tubular epithelium. However, those that had also received G. glabra showed a normal histopathology. Findings from this study indicate that in mouse models, gentamicin‐induced kidney damage can be reversed or ameliorated by administering G. glabra, so it can be considered as an effective complimentary therapy.
Knowledge and Awareness of Physicians About Rational Antibiotic Use and Antimicrobial Resistance Before and After Graduation: A Cross-Sectional Study Conducted in Malatya Province in Turkey

Background We aimed to evaluate the level of theoretical knowledge of rational antibiotic use and awareness about emergence of multidrug resistance (MDR) among the senior students at a medical school and the actively-working family physicians. Methods This cross-sectional research was carried out between 1 February and 30 April 2019 in Malatya province. Two-hundred twenty-five senior students in the Inonu University Medical School (Group 1) and 230 actively-working family physicians in Malatya primary health care services who were found to be eligible (Group 2) were included in this study. Power analysiscalculated the minimum of 240 participants with a proportion difference of 0.18 between the groups, a type I error of 0.05 and a type II error of 0.20. A questionnaire including seven sections and 28 questions was applied to the participants. Results Doctors were more hesitant in pre-graduation and more self-confident in the post-graduation period for the decision to start antibiotic treatment. In addition, doctors forget their theoretical knowledge of antibiotics over time and are unable to follow current developments after graduation. The most important concern in the pre-graduation period was the choice of antibiotics from the wrong group, while in the post-graduation period it is the fear of the presence of unproven infection. Conclusion Physicians’ antibiotic prescribing habits, attitudes and behaviors vary before and after graduation. Sustainable education for antibiotic use for physicians after graduation can contribute positively to reduce of antimicrobial resistance rates and to increase awareness about the use of rational antibiotics.
Complete mitochondrial genome of the giant root-rat (Tachyoryctes macrocephalus)

Abstract The endangered giant root-rat (Tachyoryctes macrocephalus, also known as giant mole rat) is a fossorial rodent endemic to the afro-alpine grasslands of the Bale Mountains in Ethiopia. The species is an important ecosystem engineer with the majority of the global population found within 1000 km2. Here, we present the first complete mitochondrial genome of the giant root-rat and the genus Tachyoryctes, recovered using shotgun sequencing and iterative mapping. A phylogenetic analysis including 15 other representatives of the family Spalacidae placed Tachyoryctes as sister genus to Rhizomys with high support. This position is in accordance with a recent study revealing the topology of the Spalacidae family. The full mitochondrial genome of the giant root-rat presents an important resource for further population genetic studies.
Evaluation of Antiplasmodial Activity of Hydroalcoholic Crude Extract and Solvent Fractions of Zehneria scabra Roots Against Plasmodium berghei in Swiss Albino Mice

Background Since drug resistance makes controlling malaria parasites a major challenge, these pioneering researchers explore and discover new novel drugs from a variety of sources. As a result, this study aimed to assess the anti-plasmodial activity of hydroalcoholic crude extract and solvent fractions of Zehneria scabra roots in mice infected with Plasmodium berghei. Methods The antimalarial activity and safety profile of Zehneria scabra extracts were tested in a mouse model using four-day suppressive, prophylactic, and rane’s tests against chloroquine-sensitive Plasmodium berghei. Mice were divided into five groups at random: group I received distilled water (10 mL/kg), group II, III, and IV received 200, 400, and 600 mg/kg of the extract, respectively, and group V received chloroquine (25 mg/kg). The antimalarial activity of the extract was determined using parasitemia levels, survival time, rectal temperature, and weight variation. Results At all dose levels, the crude extract and solvent fractions of Zehneria scabra showed significant (p<0.05 to p<0.001) chemosuppression, with the crude extract and butanol fraction showing the highest chemosuppression (73.09% and 74.09%, respectively). Apart from suppressing parasitemia, the extract also increased survival time and secured packed cell volume reduction substantially (p<0.05 to p<0.001), while the crude extract had no significant impact on body weight or rectal temperature reduction in four-day suppressive and prophylactic models. Conclusion The result designated that Zehneria scabra is endowed with significant antimalarial activity. These results thus support the traditional use of Zehneria scabra, for the treatment of malaria.
Relationship Between Serum Fibrinogen Level and Depressive Symptoms in an Adult Population with Spinal Cord Injury: A Cross-Sectional Study

Purpose Depression is associated with an inflammatory immune response. There are minimal data regarding the association of inflammatory markers with depression in patients with spinal cord injury (SCI). We aimed to investigate the association of inflammatory markers with depression in middle-aged and elderly SCI patients. Methods Data were obtained from the Midlife in the United States (MIDUS) study, a longitudinal study of a representative sample of the adult population. We analyzed the associations of serum levels of fibrinogen, interleukin-6, tumor necrosis factor-ɑ, and C-reactive protein with depressive symptoms. Results The median participant age was 52.5 years; 44.9% of participants were men. Multivariate linear regression analyses showed that an increased serum fibrinogen level (Sβ = 0.114, p = 0.005) was associated with higher Centre for Epidemiological Studies-Depression (CES-D) scores after adjustment for age, sex, body mass index (BMI), ethnicity, education, marital status, smoking, alcohol use, exercise, perceived stress score, and cardiovascular disease (CVD). Multivariate logistic regression analysis showed that an increased serum fibrinogen level was independently associated with a history of depression (odds ratio [OR] = 1.240, 95% confidence interval [CI] = 1.103–1.997, p = 0.012) and depressive symptoms (OR = 1.884, 95% CI = 1.165–2.499, p < 0.001; CES-D score ≥ 16) after adjustment for confounding factors. Stratified analysis revealed that the association between serum fibrinogen level and depressive symptoms was affected by antidepressant use. Conclusion Serum fibrinogen level had a significantly positive association with depressive symptoms in middle-aged and elderly patients with SCI. Future longitudinal cohort studies should evaluate the possible use of serum ﬁbrinogen for diagnosis of depression in SCI patients.
“Can Someone as Young as You Really Feel That Much Pain?” – A Survey on How People With Fibromyalgia Experience Healthcare in Sweden

Background Research show that fibromyalgia has low credibility in healthcare, leading to poor treatment, lack of knowledge and disinterest. Therefore, people with fibromyalgia feel frustration, fear, anxiety and disappointment. Objective: The aim of this study was to explore the experiences of people with fibromyalgia in their encounters with healthcare personnel in Sweden. Method: A cross-sectional design, where 409 people with fibromyalgia answered an anonymous online patient-reported experience measure, developed specific for the study, with six closed questions and one open-ended question. Descriptive statistics were analysed by response frequencies. Correlation analysis were performed between demographic and clinical variables with the answers from the closed questions. Free-text answers were analysed with content analysis. Results: A third experienced the treatment as bad (34%) and that they were not being taken seriously (30.5%). Almost half (47%) always or mostly felt fear of seeking healthcare related to fibromyalgia and that the health care personnel did not understand their diagnosis (46%). The majority (54%) experienced that the health care personnel did not understand how fibromyalgia affected them or how they could help them. The findings were confirmed in the free-text answers that were categorized into: Scepticism and disregard, Ignorance and disinterest and Professionalism and empathy. There were positive significant correlations between age and five of the questions (ρ = .105–.181, p < .05–p < .01), indicating that lower age is correlated with a worse experience. Furthermore, the duration of fibromyalgia showed a significant correlation with feeling afraid of seeking healthcare because of fibromyalgia (ρ = .144, p < .01), the shorter duration, the greater was the fear of seeking healthcare. Conclusion: As a third of patients with fibromyalgia had bad experiences with healthcare, especially younger patients, knowledge about fibromyalgia needs to be increased and the patients should be taken seriously and treated respectfully, as well as given adequate support.
Milestone Report #2: Direct Evaporator Leak and Flammability Analysis Modifications and Optimization of the Organic Rankine Cycle to Improve the Recovery of Waste Heat

The direct evaporator is a simplified heat exchange system for an Organic Rankine Cycle (ORC) that generates electricity from a gas turbine exhaust stream. Typically, the heat of the exhaust stream is transferred indirectly to the ORC by means of an intermediate thermal oil loop. In this project, the goal is to design a direct evaporator where the working fluid is evaporated in the exhaust gas heat exchanger. By eliminating one of the heat exchangers and the intermediate oil loop, the overall ORC system cost can be reduced by approximately 15%. However, placing a heat exchanger operating with a flammable hydrocarbon working fluid directly in the hot exhaust gas stream presents potential safety risks. The purpose of the analyses presented in this report is to assess the flammability of the selected working fluid in the hot exhaust gas stream stemming from a potential leak in the evaporator. Ignition delay time for cyclopentane at temperatures and pressure corresponding to direct evaporator operation was obtained for several equivalence ratios. Results of a computational fluid dynamic analysis of a pinhole leak scenario are given.
An Environmental Scan and Evaluation of Quality Indicators Across Canadian Kidney Transplant Centers

Background: Kidney transplantation is the optimal treatment for an individual requiring kidney replacement therapy, resulting in improved survival and quality of life while costing the health care system less than maintenance dialysis. Achieving and maintaining a kidney transplant requires extensive coordination of several different health care services. To improve the quality of kidney transplant care, quality metrics or indicators that encompass all aspects of the individual’s journey to transplant should be measured in a standardized fashion. Objective: To identify, categorize, and evaluate strengths and weaknesses of kidney transplant quality indicators currently being used across Canada. Design: An environmental scan of quality indicators being used by kidney organizations and programs. Setting: A 16-member volunteer pan-Canadian panel with expertise in nephrology, transplant, and quality improvement. Sample: Transplant programs, as well as provincial transplant and kidney agencies across Canada. Methods: Indicators were first categorized based on the period of transplant care and then using the Institute of Medicine and Donabedian frameworks. A 4-member subcommittee rated each indicator using a modified version of the Delphi consensus technique based on the American College of Physician/Agency for Healthcare Research and Quality criteria. Consensus ratings were subsequently shared with the entire 16-member panel for additional comments. Results: We identified 46 measures related to transplant care across 7 Canadian provinces (9 referral and evaluation, 9 waitlist activity and outcomes, 6 hospitalization for transplant surgery, 12 posttransplant care, 6 organ utilization, 4 living donor). We rated 24 indicators (52%) as necessary to distinguish high-quality from low-quality care, most of which measured effective (n = 10) or efficient (n = 6) care. Only 7 (15%) of 46 indicators evaluated person-centered or equitable care. Fourteen common indicators were measured by 5 of 7 provinces, 10 of which were deemed “necessary,” measuring safe (n = 2), effective (n = 5), efficient (n = 2), and equitable (n = 1) care. Limitations: The panel lacked patient and allied health representation. Conclusions: There are a large number of kidney transplant quality indicators currently being used in Canada, some of which are common across provinces and focus primarily on measuring effective care. Person-centered and equitable care indicators were lacking, and only half of these indicators were deemed “necessary” for quality improvement. Our results should complement ongoing work to achieve national consensus on the standardization of quality indicators in kidney transplantation.
Complement C7 is Specifically Expressed in Mesangial Cells and is a Potential Diagnostic Biomarker for Diabetic Nephropathy and is Regulated by miR-494-3p and miR-574-5p

Background Diabetic nephropathy (DN) is the leading cause of end-stage renal disease, but it remains relatively underdiagnosed. Objective In this study, we aimed to explore the key regulatory pathways and potential biomarkers related to DN using integrated bioinformatics analysis and validation. Methods First, the microarray data of the GSE30528 and GSE96804 datasets were downloaded from the Gene Expression Omnibus (GEO) database, and differentially expressed genes (DEGs) were screened. Then, weighted gene coexpression network analysis (WGCNA), gene ontology (GO) annotation, gene set enrichment analysis (GSEA) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to identify key pathways and genes. qRT-PCR and receiver operating characteristic (ROC) curves were used to validate our results. Furthermore, single-cell RNA sequencing (scRNA-seq) data were reanalyzed to investigate the expression specificity of C7 in DN cells. An online database search and luciferase reporter assay identified the target relationship between miRNAs and C7. Results The “complement and coagulation cascades” were significantly enriched, and complement C3 and C7 were candidate markers. The receiver operating characteristic (ROC) curve revealed that C7 had significant diagnostic value (AUC=0.865) in DN. Through scRNA-seq reanalysis, we found that C7 was specifically elevated in mesangial (MES) cells of DN. Moreover, we found that the expression of C7 was regulated by miR-494-3p and miR-574-5p. Conclusion This is the first study to reveal that C7 is specifically expressed in mesangial cells, is a potential diagnostic biomarker for diabetic nephropathy, and is regulated by miR-494-3p and miR-574-5p.
Artificial decellularized extracellular matrix improves the regenerative capacity of adipose tissue derived stem cells on 3D printed polycaprolactone scaffolds

Ideal tissue engineering frameworks should be both an optimal biological microenvironment and a shape and stability providing framework. In this study we tried to combine the advantages of cell-derived artificial extracellular matrix (ECM) with those of 3D printed polycaprolactone (PCL) scaffolds. In Part A, both chondrogenic and osteogenic ECMs were produced by human adipose derived stem cells (hASCs) on 3D-printed PCL scaffolds and then decellularized to create cell free functionalized PCL scaffolds, named acPCL and aoPCL respectively. The decellularization resulted in a significant reduction of the DNA content as well as the removal of nuclei while the ECM was largely preserved. In Part B the bioactivation and the effect of the ac/aoPCL scaffolds on the proliferation, differentiation, and gene expression of hASCs was investigated. The ac/aoPCL scaffolds were found to be non-toxic and allow good adhesion, but do not affect proliferation. In the in vitro investigation of cartilage regeneration, biochemical analysis showed that acPCL scaffolds have an additional effect on chondrogenic differentiation as gene expression analysis showed markers of cartilage hypertrophy. The aoPCL showed a large influence on the differentiation of hASCs. In control medium they were able to stimulate hASCs to produce calcium alone and all genes relevant investigated for osteogenesis were significantly higher expressed on aoPCL than on unmodified PCL. Therefore, we believe that ac/aoPCL scaffolds have a high potential to improve regenerative capacity of unmodified PCL scaffolds and should be further investigated.
Circular RNA Circ_0003221 Promotes Cervical Cancer Progression by Regulating miR-758-3p/CPEB4 Axis

Background Circular RNAs (circRNAs) play crucial roles in the development and progression of various cancers, including cervical cancer. However, the role and regulatory mechanism of circ_0003221 in cervical cancer are still unclear. Methods The expression of circ_0003221, microRNA-758-3p (miR-758-3p), cytoplasmic polyadenylation element-binding protein 4 (CPEB4) was detected by quantitative real-time PCR (qRT-PCR). Cell Counting Kit-8 (CCK-8), colony formation, and 5-Ethynyl-2ʹ-deoxyuridine (Edu) assays were utilized to determine cell proliferation. Cell cycle distribution was analyzed by flow cytometry. Cell migration and invasion were detected by transwell assay. All protein levels were detected by Western blot assay. The interaction between miR-758-3p and circ_0003221 or CPEB4 was confirmed by dual-luciferase reporter, RNA immunoprecipitation (RIP) and RNA pull-down assays. Mice xenograft model of cervical cancer was established to verify the function of circ_0003221 in vivo. Results Circ_0003221 was upregulated in cervical cancer tissues and cells. Knockdown of circ_0003221 suppressed cell proliferation, migration, invasion, and EMT and induced cell cycle arrest in cervical cancer cells. MiR-758-3p was a direct target of circ_0003221, and miR-758-3p inhibition reversed the effects of circ_0003221 knockdown in cervical cancer cells. Moreover, CPEB4 was identified as a direct target of miR-758-3p, and miR-758-3p exerted its anti-cancer role by targeting CPEB4. Furthermore, circ_0003221 acted as a sponge of miR-758-3p to upregulate CPEB4 expression. In addition, circ_0003221 silence also suppressed tumor growth and EMT in vivo. Conclusion Circ_0003221 knockdown inhibited cervical cancer progression via modulating miR-758-3p/CPEB4 axis, which might suggest a new insight into the pathogenesis of cervical cancer.
