Objective To explore the association of lectin-like oxidized low-density lipoprotein (oxLDL) receptor-1 (LOX-1),CX3C chemokine receptor 1 (CX3CR1) with coronary artery stenosis disease and its outcomes.Methods A case-control study was conducted.A total of 176 cases of coronary artery stenosis which were confirmed coronary artery stenosis ≥ 50％ by coronary angiography(CAG) were served as case group from department of cardiology of TEDA International Cardiovascular Hospital of Tianjin from May 2011 to April 2013.A total of 129 patients without coronary artery lesion by CAG from this hospital in the same period were served as control group,which has no history of heart disease,liver and kidney dysfuction,brain disease,hematological disease,other disorders that could bring out atherosclerosis and thrombosis.General information and laboratory parameters,LOX-1,CX3CR1,uric acid (UA) and creatinine (CREA) were measured in 2 groups.These parameters of each group were compared,the levels of LOX-1 and CX3CR1 in one-vessel stenosis were compared than that in multi-vessels stenosis in case group,the correlations between LOX-1,CX3CR1 and Gensini score and other variables were analyzed.Comparison of the levels of LOX-1 and CX3CR1 between major adverse cardiovascular events (MACEs) group and nonmajor adverse cardiovascular event (MACE) group was made during follow up 1.5 years.MACEs in patients with different levels of LOX-1 and CX3CR1 were compared during 1.5-year follow up.All of the data were analyzed by SPSS 16.0 software.The independent-samples T test,Mann-Whitney U test,Chi-square test,Spearman correlation,Binary Logistic Regression and Kaplan-Meier probability were adopted for data analysis.Results Comparison between case group and control group,LOX-1:3.72 (1.44,8.15) μg/L vs 0.75(0.50,1.19) μg/L,z =11.072,P ＜0.001 ;CX3CR1:(2.82 ± 1.85) μg/L vs (2.32 ±0.79) μg/L,t =2.021,P ＜ 0.05 ; UA:(351.34 ± 94.82) μmol/L vs (326.74 ± 79.51) μmol/L,t =2.094,P ＜ 0.05 ;CREA:(70.86 ± 20.94) μmol/L vs (65.55 ± 12.96) μmol/L,t =2.077,P ＜ 0.05.CX3CR1 level was significantly higher in patients with multi-vessels stenosis (2.84 ± 1.78) μg/L than that in one-vessel stenosis(2.48 ± 1.64) μg/L,there was significance in difference (t =2.207,P ＜ 0.05).There were no statistically significant correlation between LOX-1,CX3CR1 and Gensini score (R was 0.032,0.079 respectively,P＞ 0.05).LOX-1 was negatively related to left ventricular ejection fraction(LVEF) (R =-0.272,P ＜ 0.01),but positively related to left ventricular end-diastolic diameter (LVDD)(R =0.190,P＜0.05),positively related to UA (R =0.121,P ＜ 0.05).Comparison between MACE group and nonMACE group,LOX-1:7.38(4.97,11.88)μg/L vs 3.52(1.45,7.75) μg/L,z =2.762,P ＜0.01;CX3CRl:(4.02 ±2.90) μg/L vs (2.67 ± 1.48) μg/L,t =3.086,P ＜0.01.LOX-1 and TG were independent risk effects of coronary artery stenosis disease.MACEs were increased in patients with high levels of LOX-1 after PCI during following up 1.5 years (comparison between high-LOX-1 group and lowLOX-1 group,the probability of non-MACE was 87.1％ (115/132) vs 97.7％ (43/44),Log-ranK test,x2 =6.957,P ＜ 0.01).Conclusions LOX-1 and CX3CR1 may be involved in the process of coronary artery stenosis,and a high level of LOX-1 may be associated with left ventricular systolic dysfunction in patients with coronary artery stenosis.Elevated LOX-1 level are closely related to afterwards MACE incidence after PCI in patients with coronary artery stenosis.

The actual efficacy of acupuncture on cerebral infarction was explored in clinical practice. The retro spective cohort study was adopted to investigate 344 cases via inpatient's medical cases. According to whether acupuncture was received or not, an acupuncture group (207 cases) and a non-acupuncture group (137 cases) were divided. The matching method, regression method and weighting method of propensity score (PS) were adopted, and the efficacy on muscle strength was taken as effect index so that the specific impacts of acupuncture were ex plored on the muscle strength in the patients of cerebral infarction. Before matching, COX regression model and Logistic regression model were used. And PS hierarchical regression, PS inverse probability weighting method (IPTW) and PS standardized mortality weighting method (SMRW) were applied to the analysis on the relationship between the muscle strengthen changes and the total effective rate in the two groups. It was found that the efficacy in the acupuncture group was better than that in the non-acupuncture group, indicating the significant difference (P<0.05). Meanwhile, the rehabilitation therapy also brought the obvious impacts on the efficacy evaluation (OR=2.737, P=0.0055). After PS matching, the Logistic regression model was used to analyze whether acupuncture or rehabilitation therapy impacted the total effective rate of muscle strength. The results showed that the efficacy was impacted apparently with the rehabilitation therapy involved (OR=2.930, P=0.0247). Without the rehabilitation effect considered, the efficacy in the acupuncture group was better potentially than that in the non-acupuncture group, but without significant difference (OR=2. 235, P=0,058 7). All of these indicate that on the basis of routine treatment, without the effect of rehabilitation therapy considered, acupuncture improves in tenden cy of the muscle strength of the patients with cerebral infarction. However, it is expected to increase the study medical cases for further verification.

Objective:To systematically evaluate the intervention effect of oral immunotherapy (OIT) on ventilator-associated pneumonia (VAP) of premature infants.Methods:This study searched the Cochrane Library, PubMed, Embase, Web of Science, CINAHL, Chinese Biomedical Literature Service System, China National Knowledge Infrastructure (CNKI) , WanFang Database and VIP Database, and conducted a comprehensive search for randomized controlled trials of OIT applied to premature infants published from database establishment to October 2020. Two researchers independently screened literature, extracted data, and evaluated methodological quality. RevMan 5.3 software was used for Meta-analysis.Results:A total of 8 studies were included, with a total of 351 premature infants in the intervention group and 352 premature infants in the control group. Meta-analysis results showed that OIT could reduce the incidence of VAP in premature infants [ RR=0.36, 95% CI (0.23-0.56) , P<0.05] and the detection rate of pathogenic microorganisms in the tracheal tube [ RR=0.33, 95% CI (0.18-0.59) , P=0.000 2], and could shorten the length of hospital stay [ MD=-6.70, 95% CI (-13.34--0.06) , P=0.05]. However, there was no statistically significant difference in the mechanical ventilation time, detection rate of oropharyngeal pathogenic microorganisms and mortality rate between the two groups after the intervention (all P>0.05) . Conclusions:OIT can reduce the incidence of VAP in premature infants and the detection rate of pathogenic microorganisms in the tracheal tube, and shorten the length of hospital stay to a certain extent. However, high-quality, large-sample, multi-center randomized controlled studies are still needed for further verification in the future.

Objective To investigate the diagnosis and prognosis value of plasma microRNA-30d (miR-30d)in acute coronary syndrome(ACS)patients.Methods It retrospectively recruited 170 cases of ACS patients from TEDA International Cardiovascular Hospital between September 2011 to February 2012, including 70 STEMI(male 54,female 16), 52 NSTEMI(male 34,female 18),48 UAP(male 29,female 19).At the same time,41 healthy controls(male 24,female 17)were enrolled into the study.Plasma miR-30d levels were determined by real-time quantitative PCR.In order to evaluate the dynamic change of miR-30d and other cardiac biomarkers,20 plasma samples of AMI patients were collected at 0-3 h,4-6 h,7-9 h, 10-12 h after pectoralgia.ROC curves and Kaplan-Meier survival curve were used to investigate clinical value of miR-30d in ACS.Results At 0-3 h after pectoralgia, miR-30d were significant higher in STEMI 7.208(0.170-11 070.735)and NSTEMI 7.989(0.836-151.391)than the controls 1.561(0.044-17.520)（Z1＝-5.792,Z2 ＝-6.113,P＜0.001）, but there were no statistic differences between UAP 1.073 （0.051-11.095）patients and the controls（Z＝-0.325,P＝0.745）.In 20 AMI patients,miR-30d levels peaked at 4-6 h and then dropped following 7-9 h, both earlier than cTnI, and the variation tendency was positive correlated with cTnI（r＝0.402,P＜0.01）.At 0-3 h after pectoralgia, the AUC, sensitivity and specificity of miR-30d for differentiating AMI and UAP were 0.882（95％ CI:0.830-0.935）,0.795（95％CI:0.711-0.861）and 0.854（95％ CI:0.716-0.935）respectively.When combined miR-30d and cTnI, the diagnostic AUC and specificity were 0.937（95％ CI: 0.902-0.972）and 0.937（95％ CI:0.818-0.984）,both enhanced when compared with miR-30d or cTnI alone.Kaplan-Meier survival curves revealed that there were no significant correlations between the miR-30d levels and MACE in both 30 days and 12 months（χ$lt@span sup=1$gt@2$lt@/span$gt@＝0.506,P＝0.477 and χ$lt@span sup=1$gt@2$lt@/span$gt@＝0.002, P＝0.963 respectively）.Conclusion Plasma miR-30d may be used as a potential biomarker for early diagnosis, but not prognosis in ACS patients.

Objective:To comprehensively evaluate the clinical application status of oral movement intervention in preterm infants, analyze the obstacles in the process of clinical application of the best evidence and formulate countermeasures, so as to provide reference for clinical evidence transformation.Methods:Based on the theoretical guidance of the "Clinical Application Model of Evidence" of the Joanna Briggs Institute (JBI) Evidence-Based Health Care Center in Australia, 12 pieces of the best evidence for oral movement intervention in premature infants were included, and 13 review indicators were formulated. From May to July 2021, a status review was conducted in Department of Neonatology in Suzhou Hospital Affiliated to Nanjing Medical University. The Ottawa Model of Research Use (OMRU) was used to analyze the barriers and facilitators in the process of evidence application and formulate effective intervention strategies and action plans.Results:Among the 13 reviewed indicators, only 2 items had a compliance rate of 100%, 2 items had a compliance rate of more than 60%, 6 items had a compliance rate of less than 60%, and 3 items had a compliance rate of 0. The main obstacle factors were lack of standardized process and assessment tools, lack of oral motor intervention related knowledge and training for preterm infants, increased clinical workload due to evidence transformation and the low level of knowledge and action among medical staff. The main promoting factors were support from managers for the development and reform of evidence-based learning, good learning atmosphere for doctors and nurses, departments with material and hardware conditions for evidence transformation, effective evidence, and parents' willingness to accept the reform. Through analysis, countermeasures were drawn up to formulate feasible and suitable standardized procedures and introduce assessment tools. Managers formulated and implemented incentive policies, adopted various training methods, strengthened quality supervision in the process of evidence transformation, timely gave feedback of progress results and improved human resource allocation.Conclusions:There is a certain gap between the best evidence of oral movement intervention in premature infants and the current clinical nursing practice. It is necessary to formulate corresponding countermeasures according to the obstacle factors and promoting factors, promote the evidence transformation and constantly promote the evidence-based practice of oral movement intervention in premature infants.
