ObjectiveTo investigate the relationship of 24-hour ambulatory pulse pressure (24hPP) with left ventricular mass index (LVMI) in elderly essential hypertension patients. MethodsThe data of 110 elderly patients with essential hypertension from January to December 2012 were collected in the study. All patients received 24-hour ambulatory blood pressure monitoring and echoeardiographic examination 24hPP and LVMI were calculated according to the results of 24-hour ambulatory blood pressure monitoring and echocardiographic measurements. The patients were divided into group A [24hPP<60 mm Hg (1 mm Hg=0.133 kPa), n=70] and group B (24hPP≥60 mm Hg, n=40). ResultsThe 24-hour systolic blood pressure and 24hPP for patients in group B were significantly higher than those in group A (P<0.001). Compared with group A patients, the interventricular septal thickness, left ventricular posterior wall thickness, left ventricular mass and left ventricular mass index were significantly higher in group B (P<0.05). Pearson correlation analysis showed that 24hPP had a positive correlation with LVMI in the elderly essential hypertension patients (r=0.33, P<0.001). Multiple stepwise regression analysis showed that 24hPP was the main factor for the increase of LVMI in elderly essential hypertension patients (β=0.90, P<0.001). ConclusionThe 24hPP is positively correlated with LVMI in elderly essential hypertension patients. The 24hPP is an important risk factor for left ventricular structural damage in elderly essential hypertensive patients.
ObjectivesTo assess the methodological quality of clinical practice guidelines of cervical cancer in China published from 2014 to 2018.MethodsCNKI, WanFang Data, CBM, VIP, Medlive.cn, the National Guideline Clearinghouse, PubMed, The Cochrane Library and EMbase were searched for cervical cancer clinical practice guidelines published in China from January 1st, 2014 to December 31st, 2018. Four reviewers searched and selected the literature independently according to the inclusion and exclusion criteria and assessed the methodological quality of the included guidelines by using AGREE Ⅱ.ResultsA total of 9 guidelines were included. The average score for each area was: scope and purpose 75.47%, stakeholders’ involvement 35.09%, the rigor of development 43.70%, clarity of presentation 87.74%, applicability 80.76%, and editorial independence 0%.ConclusionsThe quality of cervical cancer clinical practice guidelines in China requires further improvement.

Abstract： Quality of life （QOL） refers to an individual’s perception and subjective evaluation of their health and well-being, and has become an important index to evaluate the outcomes of clinical treatment in the last past decades. There are a large number of different instruments to evaluate QOL, and the 36-Item Short Form Health Survey （SF-36） is currently one of the most widely used instruments. In recent years, SF-36 has been used to evaluate QOL of valvular heart disease patients to investigate the risk factors those influence their postoperative QOL, provide more preoperative evaluation tools for clinical physicians, and improve postoperative outcomes of patients with valvular heart disease. However, it is now just the beginning to use SF-36 to examine QOL of valvular heart disease patients. Because of significant differences in sample size, follow-up period, country and culture, current research has some controversial results. This review focuses on the progress in evaluating QOL in postoperative patients with valvular heart disease using SF-36.
Mitochondrial quality control includes mechanisms such as mitochondria-derived vesicles, fusion / fission and autophagy. These processes rely on the collaboration of a variety of key proteins in the inner and outer membranes of mitochondria to jointly regulate the morphological structure and functional integrity of mitochondria, repair mitochondrial damage, and maintain the homeostasis of their internal environment. The imbalance of mitochondrial quality control is associated with leukemia. Therefore, by exploring the mechanisms related to mitochondrial quality control of various leukemia cells and their interactions with immune cells and immune microenvironment, this article sought possible targets in the treatment of leukemia, providing new ideas for the immunotherapy of leukemia.
Objective To analyze the research hotspots and trends of Chinese literature on medical quality evaluation indicators in China in recent years. Methods We searched for relevant Chinese literature on medical quality evaluation indicators on China National Knowledge Infrastructure from January 2000 to December 2024, and analyzed the annual publication volume, authors and institutions, research hotspots and frontiers. Results Finally, 177 articles were included in the literature. From 2000 to 2024, the number of Chinese literature on medical quality evaluation indicators in China showed a fluctuating upward trend, reaching 15 articles per year in both 2015 and 2024. The issuing units mainly included the National Institute of Hospital Administration, the School of Public Health of Peking University, Huazhong University of Science and Technology, etc. The publishing team mainly included author teams such as MA Xiemin, LIANG Minghui, XIA Ping, etc. The high frequency keywords and top 10 keywords for centrality ranking included medical quality, evaluation indicators, indicator system, Delphi method, evaluation, evaluation system, quality evaluation, indicators, clinical pathways, and hospital management. “Case classification” was the earliest emerging term in the study of medical quality evaluation indicators. In terms of burst intensity, the top 5 keywords for burst intensity included Delphi method, case classification, problem, data quality, and evidence-based evaluation. Conclusion The publishing institutions and research teams of Chinese literature on medical quality evaluation indicators in China are relatively loose, and there are still problems such as insufficient practical application of medical quality evaluation indicators and single research tools and methods.
ObjectiveTo investigate the influence of evidence-based nursing intervention on the treatment effect and quality of life in patients with peritoneal dialysis. MethodSixty-four patients who underwent peritoneal dialysis between January 2013 and December 2014 in our hospital were randomly divided into control group (n=32) and intervention group (n=32) . The control group received routine nursing and the intervention group received evidencebased nursing intervention. Urea clearance index (KT/V), serum albumin and hemoglobin levels were detected for both groups of patients before and after nursing intervention. Generic Quality of Life Inventory (GQOLI)-74 scale was used to assess patients' quality of life. ResultsAfter nursing intervention, KT/V, serum albumin and hemoglobin levels in the intervention group were significantly higher than those in the control group (P<0.05) . The scores of such items as physical function, psychological function, social function and overall evaluation in the GQOLI-74 scale in the intervention group were significantly higher than those in the control group (P<0.05) . ConclusionsEvidence-based nursing intervention can effectively improve the treatment effect and quality of life in patients with peritoneal dialysis, which is worthy of clinical popularization and application.
