ABSTRACT
Purpose@#Ankle pump exercises (APE) have been widely used in clinical practice. However, best practices for APE have not been established. Recognize the most effective frequency of APE for improving lower extremity hemodynamics and establish recommendations in clinical practice. @*Methods@#Therefore, a systematic review and network meta-analysis (NMA) was performed according to PRISMA-NMA. Six English databases (Pubmed, Medline, CINAHL, Embase, the Cochrane library and ProQuest) and four Chinese databases (CNKI, Wanfang, VIP and Sinomed) were searched. Randomized controlled trials (RCTs) and quasi-experimental studies investigating the effects of different frequencies of APE on lower limb hemodynamics published before July 2022 were included. The reference list was also searched. Seven studies (one RCTs and six quasi-experimental studies) were included in the systematic review and five studies (one RCTs and four quasi-experimental studies) were included in the NMA. The risk of bias was assessed using the Cochrane and Joanna Briggs Institute tools. The NMA was performed using the R software (version 4.2.1) and OpenBUGS (version 3.2.3). @*Results@#The results of the NMA showed that a frequency of every 3–4 s the most effective in improving lower extremity hemodynamics (P =.85), followed by every 1–2 s (P = .81), every 5–6 s (P=.32) and less than every 10 s (P =.02). Subgroup analysis failed to find a difference between healthy participants and those with unilateral total hip arthroplasty or fracture (MD = −0.23, 95% CI-5.92 to 4.61). @*Conclusions@#Consequencely, for adult patients, with or without lower extremity disease, a frequency of every 3–4 s can be recommended as the optimal frequency of APE in clinical care practice.Registered number on PROSPEROCRD42022349365. https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=349365.
ABSTRACT
Objective:To investigate the current situation of core competence of anesthesiology nurses in China, and to provide basis for formulating and perfecting the training curriculum of anesthesiology nurses.Methods:The cluster sampling method was used, and 231 nurses in the department of anesthesiology were investigated by using the general data questionnaire and the self-assessment form of core competence of specialized nurses in the department of anesthesiology.Results:Anesthesiology nurses scored (3.7±0.5) points in their core competencies, of which 43.2% and 36.4% had complete mastery of humanistic literacy, and communication and coordination skills, respectively, and only 4.3% of them had mastered scientific research ability.The core competence scores of anesthesiology nurses with the title of head nurse or above positions and deputy chief nurse or above titles were significantly higher than those of other positions and titles ( P<0.05). Conclusions:The self-evaluation of core competence of specialized nurses in anesthesiology department is at a medium level.There are differences in core competencies among nurses in the department of anesthesiology with different positions and titles.It is suggested that the training of specialized nurses should be guided by core competence.
ABSTRACT
The management of healthcare services for the suspected cases in non-designated hospitalsis a serious concern in controlling coronavirus disease 2019 (COVID-19) epidemic. Owing to the complexity of care providers, large requirement of medical supplies as well as the possible needs off frequent transfers, the major difficulty is preventing the coronavirus from spreading while caring the suspected critical cases before the 2019 novel coronavirus ribonucleic acid test results are reported. For the purpose of enhancing the prevention of the propagation of COVID-19, this article puts emphasis on the following aspects in non-designated hospital Peking University Third Hospital: preparatory procedures of receiving critical suspected patients, the management of medical personnel during the waiting session of RNA test results, the delivering procedures of testing samples, the management of referred medical wastes, daily operations including the cleaning and sanitizing of caring units and the management of related patients after the testing session.
ABSTRACT
Objective@#To understand the epidemiologic features of the rabies in Xishuang banna prefecture of Yunnan province, China in 2008-2017 and the viral molecular-evolution characteristics.@*Methods@#The data of rabies case questionnaire were collected. The brain tissue samples from mad dogs, suspicious sick dogs and human brain tissue, saliva and cerebrospinal fluid samples from rabies patients were collected in Xishuangbanna. Coding region of nucleoprotein and glycoprotein genes were amplified by RT-PCR and sequenced. Homology and phylogenetic analysis were performed using the relevant bioinformatics software.@*Results@#A total of 62 cases of human rabies were occurred in 28 districts of the 3 counties, Xishuangbanna prefecture in 2008-2017. Of them, 37 cases in Jinghong county, 15 in Menghai county and 10 in Mengla county. In which 48 cases were bitten by domestic dogs (77.42%), 11 cases were bitten by wild dogs (17.74%). Rabies case was occurred every year in the past decade. The seasonal incidence was not obvious. The majority of patients were aged from 30 to 59 years-old, with the youngest 1 year-old and the eldest 91 year-old. The male to female ratio was 1.70∶1, most cases were farmers. The nucleotide sequences of nucleoprotein gene of 9 virus strains (7 from Jinghong, 1 from Menghai and 1 from Mengla) were obtained from the samples of dogs and patients. Homology and phylogenetic analyses indicated that the 5 strains belonged to clade China-Ⅰ, 3 clade China-Ⅱ and 1 clade China-Ⅵ. The nucleotide sequences of glycoprotein gene of 5 virus strains (3 from Jinghong, 1 from Menghai and 1 from Mengla) were obtained from these positive samples, and all were clade China-Ⅰ, it is same with nucleoprotein genes analysis result from these 5 virus strains. These China-Ⅰ and China-Ⅱ strains from Xishuangbanna have a closer genetic relationship with same clade strains isolated from Pu’er and other prefectures of Yunnan province as well as Sichuan, Guizhou and Guangxi. The China-Ⅵ strain from Xishuangbanna share high homology and genetic relationship with China-Ⅵ strains isolated from southwestern Yunnan and neighbouring countries such as Myanmar, Laos and Vietnam in recent years.@*Conclusions@#In Xishuangbanna, rabies mainly occurred in rural area and domestic dog was the main source of transmission. These RABV clades China-Ⅰ, China-Ⅱ and China-Ⅵ were found in this region and the China-Ⅰ was principal clade. The transmission source of China-Ⅰ and China-Ⅱ were from adjacent areas in the province and China-Ⅵ was from Myanmar and Laos.

ABSTRACT
Delta-like ligand 4(Dll4), one ligand of Notch receptors, is highly expressed in tumour vessels and is negative regulator in tumour angiogenesis. Blocking Dll4/Notch sinaling could promote tumour angiogenesis, whereas due to poor perrusion of newly forming vessels, tumour growth is inhibited, which is effective even to the tumour patients unresponsive to blocking vascular endothelial growth factor pathway. So, Dll4 is becoming a new promising target in anti-tumour theraties.
ABSTRACT
Delta-like ligand 4 (D114), one ligand of Notch receptors, was highly expressed in turnout vessels and was a negative regulator in tumour angiogenesis. Blocking D114/Notch signaling could promote tnmour angiogen-esis, whereas due to poor peffnsion of newly forming vessels, tumour growth was inhibited, which was effective even to the tumour patients unresponsive to blocking VEGF pathway. So, D114 is becoming a new promising target in anti-tumour therapies.
ABSTRACT
MicroRNAs are a class of small(about 20-24 nueleotides),endogenous,noneoding RNA molecules that regulate a wide array of physiologic processes,such as growth and developmenL In recent years,some researches show that the tissues from tumors have aberrant mieroRNA profiling compared with normal tis-sues.The abnormal miemRNA profiling can affect the genesis,proliferation,differentiation,metastasis and recur-renee of tumors.The different expressions of microRNA Can not only help for the diagnosis of tumors,but also evaluate the prognosis of tumors.Disturbing several miemRNA expressions can decrease the volumes of tumor and inhibit the peritoneal metastasis 80 as to treat the tumor by using anti-mieroRNA drugs in animal expedments.
ABSTRACT
Objective To explore whether augmentation index is an independent risk factor for coronary heart disease or not,and the relationship between augmentation index and coronary artery disease severity.Methods In the study,245 subjects who were hospitalized between Dec.2003 and Dec.2004,were classified into 4 groups and their clinical and biological characteristics and the summary of the scores in each of the eight segment and aortic pressure waveform in ascending aorta were recorded respectively.Results The larger the augmentation index was,the more the number of coronary stenosis vessels was.Linear regression analysis indicated that augmentation index was significantly correlated with grade of coronary stenosis.When augmentation index was more than 45%,the sensibility and specificity was 91.5%and 92.6%respectively.In the logistic regression model,augmentation index was the independent risk factor for coronary heart disease,and the odds ratio of coronary heart disease was 1.893.The 95%CI was 1.421~2.521.Conclusion Augmentation index is an independent risk factor for coronary heart disease and a predictor of angiographic coronary artery disease severity.
