Objective To assess the clinical value of lung ultrasound (LUS) B-lines in diagnosis of rheumatoid arthritis (RA) associated interstitial lung diseases (RA-ILD).Methods Forty-five consecutive patients with RA who underwent a high resolution computed tomography (HRCT) scan of the chest,were also examined by LUS for detection of B-lines(within 1 month independently in all patients).The B-lines score was obtained by summing the number of total 50 inter-costal spaces (ICSs) of chest wall.Pulmonary fibrosis was quantified by HRCT as previously described by the 30-point Warrick score.Results B-lines score significantly correlated with the Warrick score [(r=0.778,95％CI(0.627,0.872),P＜0.05].Receiver operating characteristic (ROC) curve confirmed that B-lines cut-off point 77[sensitivity of 100％,specificity of 64.3％ respectively,area under curve [AUC] =0.86,95％CI(0.724,0.945)] and 108[sensitivity of 90％,specificity of 88.6％ respectively,AUC=0.879,95％CI(0.747,0.957)] had an optimal power to discriminate mild (Warrick score＜8) and severe fibrosis (Warrick score＞15):Conclusion The data confirm that LUS is a useful technique to identify ILD in RA.In RA-ILD,B-lines correlate significantly with HRCT and are able to identify mild and severe degree of fibrosis.LUS is a promising non-invasive and non-ionizing strategy for screening RA-ILD.

Objective To investigate the expressions of miR-21 in clinical lung tissues,serum of lung cancer patients and X-ray irradiated A549 cells in vitro and in vivo.Methods A549 cells were irradiated with 2 and 4 Gy X-rays,and pulmonary metastasis model of lung cancer in nude mice was established to detect the expression of miR-21 in vitro and in vivo,as well as in clinical lung tissues of different pathological types serum sample of lung cancer patients and NSCLC patients whether or not received radiotherapy.The survival rate was further analyzed in the above mention NSCLC patients.Results The miR-21 expressions was up-regulated in 60.0％ of tissue samples of NSCLC patients,and it was up-regulated in 50.5％ serum samples of lung cancer patients (52 out of 103).The miR-21 expressions in lung adenocarcinoma and squamous cell carcinoma had significant difference (x2 =5.766,P ＜ 0.05).In the serum samples of 87 NSCLC patients,miR-21 was detected in 66.7％ samples from the patients of radiotherapy but only 39.6％ of patients without radiotherapy (x2 =6.321,P ＜ 0.05).Kaplan-Meier curves showed that the survival rate of patients with low miR-21 expression was higher than that with high miR-21 expression (P ＜ 0.05).Multivariate Cox regression analysis demonstrated that the miR-21 expression,regional lymph node metastasis and radiotherapy were independent prognostic factors for NSCLC patients.The expression of miR-21 was up-regulated significantly in X-ray irradiated A549 cells at different time-points after irradiation (t =-7.552--1.206,P ＜ 0.05).Furthermore,the expression of miR-21was up-regulated in the serum and lung of nude mice (t =-47.845--2.356,P ＜ 0.05).Conclusions The X-ray irradiation could up-regulate the expression of miR-21 in A549 cells in vitro and in vivo,which might be correlated with the enhanced metastasis of A549 cells.

Objective:To establish a set of scientific and reasonable indicator system of common prosperity in the field of health, so as to promote the construction and evaluation of the demonstration area of common prosperity with high quality of health.Methods:According to the requirements of promoting common prosperity demonstration area with high quality of health in Zhejiang province, the initial indicator pool was established through literature research and theoretical analysis in July 2021, and experts were convened to carry out expert brainstorming to determine indicator system in the form of meetings. Delphi method was used to conduct two rounds of expert consultation on the indicator system.Finally, the analytic hierarchy process and percentage weight method were used to calculate the indicator weight value.Results:The final indicator system included 4 first-level indicators and 30 second-level indicators. Among the first-level indicators, the weight values of the development, equilibrium, inclusiveness, and sustainability were 0.326 4, 0.242 8, 0.245 8, and 0.185 0. There were 8 second-level indicators in developmental indicator dimension, of which the indicator with the highest weight was the per capita health expectancy. The balance indicator dimension included 6 second-level indicators, of which the indicator with the highest weight was the per capita financing difference of basic medical insurance between the urban workers with the urban-rural residents. The inclusive indicator dimension included 6 second-level indicators, and the proportion of personal health expenditure to total health expenditure had the highest weight. The sustainability indicator dimension included 10 second-level indicators, and the proportion of government health expenditure in fiscal expenditure had the highest weight.Conclusions:The indicator system constructed in this research could provide certain guidance and reference for promoting the construction of common prosperity in health, and provide some reference for follow-up research in this field.

Objective:To assess the capability of seven reference medical laboratories to detect BCR::ABL1 p210 transcription levels and to compare the results among those laboratories.Methods:The interlaboratory comparison was carried out in two stages. The samples were prepared by the reference laboratory. The quantitative values of BCR::ABL1 p210 of the comparison samples covered 0.001%-0.01%, 0.01%-0.1%, 0.1%-1%, 1%-10% and>10% in each stage. Real-time quantitative PCR (RT-PCR) and dPCR (digital PCR) were used to examine the samples. The conversion factor (CF) was calculated and validated for each laboratory.Results:In the RT-PCR comparison, one laboratory was failed to detect BCR::ABL1 p210 in fourteen samples at the first stage. The results of the other six laboratories were qualified with the bias <±1.2 folds (-0.133-0.338) and 95% limits of agreement within ±5 folds (upper limit 0.147-0.785, lower limit -0.770--0.109), and the corresponding CF values were calculated and validated. In the dPCR comparison, one laboratory did not report results at the second stage. The results of the other six laboratories were qualified with the bias <±1.2 folds (-0.026-0.267) and 95% limits of agreement within±5 folds (upper limit 0.084-0.991, lower limit -0.669--0.135), and the corresponding CF values were calculated and validated. The samples with BCR::ABL1 p210 quantitative values of 0.01%-0.1%, 0.1%-1%, 1%-10% and >10% could be detected by both RT-PCR and qPCR. When the quantitative value of BCR::ABL1 p210 was 0.001%-0.01%, the detection rate of dPCR was higher than that of RT-PCR (85.56% vs. 68.00%).Conclusions:A good consistency is present among various laboratories. The quantitative value of BCR::ABL1 p210 is comparable among laboratories as shown by the CF value conversion. For quantitative detection of BCR::ABL1 p210 deep molecular reaction, dPCR has a higher positive detection rate and more advantages than RT-PCR. To ensure the accuracy and reproducibility of the BCR::ABL1 p210 test, it is imperative for every laboratory to enhance their daily quality control practices.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.
