Objective To develop a Knowledge-Attitude-Practice Questionnaire for Nursing Assistants on Humanistic Care and test its reliability and validity,in order to provide a valid tool for evaluating their humanistic care competence.Methods Based on the theory of knowledge,attitude and practice,the first draft of the questionnaire was developed through literature review,semi-structured interviews,2 rounds of Delphi expert consultation,and pre-surveys.All nursing assistants from 4 tertiary hospitals in Hubei Province were investigated by convenient sample,and the reliability and validity were tested from May to July,2024.Results 412 questionnaires were distributed and 399 valid questionnaires were recovered,with a valid questionnaire recovery rate of 96.84％.The final knowledge-attitude-practice questionnaire include 3 dimensions of knowledge,attitude and practice,with a total of 24 items and cumulative contribution rate was 65.338％.The CVI of each item in the questionnaire ranged from 0.800 to 1.000,with an average of 0.981.The confirmatory factor analysis showed that the scale model had a good fit.The total Cronbach's α coefficient of the questionnaire was 0.941,and the test-retest reliability coefficient of the questionnaire after 2 weeks was 0.923.Conclusion The knowledge-attitude-practice questionnaire has good reliability and validity,and it can be used as a valid tool for evaluating the competence of humanistic care of nursing assistants.

Objective:To investigate the protective effects and related mechanisms of Astragaloside Ⅳ(ASⅣ)alleviating Angiotensin II-induced cardiomyocyte hypertrophy.Methods:H9c2 cardiomyocytes were divided into six groups: normal control group, ASⅣ group(ASⅣ 100 μmol/L), AngⅡ group(AngⅡ 1 μmol/L), and three ASⅣ dose experiments(AngⅡ 1 μmol/L + ASⅣ 25 μmol/l group, AngⅡ 1 μmol/L+ ASⅣ 50 μmol/l group, AngⅡ1 μmol/L+ ASⅣ 100 μmol/L group), and simultaneously cultured for 24 hours.Cardiomyocyte viability was assessed by CCK8 assay, and surface area of culturedcardiomyocytes in each group was assessed by immunofluorescence assay.Atrial natriuretic peptide(ANP)mRNA expression was assessed by fluorescence real-time quantitative RT-PCR.And LC3 protein expression, an autophagy related protein, was assessed by Western blotting as well as immunofluorescence.Results:(1)AngⅡ decreased cardiomyocyte H9c2 viability in a dose-dependent manner( P<0.05). ASⅣ could inhibit the decrease of cardiomyocyte H9c2 viability in response to AngⅡ in a dose-dependent manner( P<0.05). (2)H9c2 cardiomyocytes induced by AngⅡ showed a significantly larger cell area and significantly higher ANP mRNA and ANP protein expression compared with controls.Different concentrations of ASⅣ intervention could reverse the increase of cardiomyocyte H9c2 area induced by AngⅡ and also decreased the expression of ANP protein induced by AngⅡ in a dose-dependent manner(all P<0.05). (3)Compared with the control group, the autophagy level and the expression of autophagy marker LC3II/I of H9c2 cardiomyocytes induced by AngⅡ were significantly increased(all P<0.05). ASⅣ could inhibit AngⅡ-activated autophagy, and the difference was statistically significant( P<0.05). ASⅣ inhibited the expression of LC3II/I in H9c2 cardiomyocytes stimulated by AngⅡ, and the difference was statistically significant( P<0.05). Conclusions:ASⅣ inhibits AngⅡ-induced cardiac hypertrophy by inhibiting autophagy of cardiomyocytes.

Nucleos(t)ide analogues can effectively prevent or delay disease progression in patients with chronic hepatitis B virus (HBV) infection, but the course of treatment is long and long-term medication may bring the risk of adverse drug reactions and drug resistance. Recent studies have found that HBsAg quantification has an important value in individualized antiviral treatment for patients with chronic hepatitis B. This article reviews the research advances in the value of HBsAg quantification in judgment of indication for antiviral treatment with nucleos(t)ide analogues, prediction of therapeutic outcome, and timing of drug withdrawal, and it is pointed out that HBsAg quantification can help to determine the timing of antiviral treatment and predict the treatment outcome of patients at the beginning of antiviral treatment, during the treatment process, and when drug withdrawal is considered. Further studies are needed to determine the optimal predictive thresholds for different stages of HBeAg-positive or HBeAg-negative patients, as well as the optimal time point and thresholds for predicting treatment outcome during antiviral treatment with different nucleos(t)ide analogues.

Objective The study is designed to evaluate the difference in identification for depression and clinical effectiveness of its treatment between psychiatrists and non-psychiatric Dhysieians at out-patient departments of general hospitals and to analyze its related factors.Methods Totally,680 patients who visited psychiatric clinics in nine general hospitals of Shanghai at first time were screened by psychiatrists using Composite International Diagnostic Interview(CIDI)for depression and the screening resuhs were compared to the diagnosis made by non-psychiatric physicians as goal-keepers there.Altogether 297 patients with depression were recruited and assessed using Hamilton Depression Rating Scale(HAMD)and Hamilton Anxiety Rating Scale(HAMA).A self-made questionnaire for basic information was used to assess the ability for identification of depression in non-psychiatric physicians of general hospitals.Results Psychiatrists identified depression correctly in 337 of 680 patients who visited psychiatric clinics in general hospitals at their first visit,but non-psychiatric physicians only identified 216 patients,with statistically significant difference(χ2=30.73,P=0.000).A consistent agreement on depression diagnosis between the findings by psychiatrists and by CIDI was reached with Kappa of 0.774,but Kappa for that between the findings by non-psychiatric physicians and CIDI was 0.439.Effectiveness of treatment for depression by psychiatrists was better than that by non-psychiatric physicians,with higher total score and scores for each item of HAMD four,eight and 12 weeks after treatment,respectively(P＜0.05 or P＜0.01).Length of professional work of non-psychiatric physicians and annual time for professional training in management of mental disorders associated with their ability of identification for depression(P＜0.05).Conclusion Ability of non-psychiatric physicians to identify alQd cope with depression in the psychiatric department of general hospitals was insufficient,suggesting that more importance should be attached to the management of service quality at psychiatric department of general hospitals.
