Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.

Objective: To explore the cross sectional and longitudinal relationships between children s 24 h movement behaviors and health related quality of life (HRQoL), and to reflect the impact of reallocating time between different activities on HRQoL scores using the isotemporal substitution analysis method, so as to provide a scientific basis for promoting children s health. Methods: In May 2022, a method combining cluster random sampling and convenience sampling was employed to conduct baseline survey on 397 children aged 7-10 from three primary schools in Wanzhou District of Chongqing. Children s movement behaviors were monitored using accelerometers, and their HRQoL was assessed through a health related quality of life questionnaire for children.The same questionnaire was used for assessing HRQoL of children on the follow up survery after on year(May 2023). A component based multiple linear regression model was used to analyze the relationship between children s 24 h movement behaviors and HRQoL. Results: The average daily times for children s light physical activity (LPA), moderate to vigorous physical activity (MVPA), sleep (SP), and sedentary behavior (SB) were (331.5±41.7，61.9±28.6，561.7±78.4，484.9±67.3) min, respectively. The mean baseline HRQoL score was (69.5±6.6), and it was (67.6±5.1) after one year. MVPA and SP were positively correlated with HRQoL at baseline( β =0.59,0.38) and after one year ( β =0.48, 0.39), while SB was negatively correlated with HRQoL at baseline and after one year ( β =-0.25, -0.53) ( P <0.05). An isotemporal substitution analysis showed that replacing 30 minutes of LPA or SB with MVPA increased the HRQoL scores by 1.81 and 2.79 at baseline, and by 1.37 and 2.12 after one year. Additionally, replacing SB with SP increased the HRQoL scores by 0.61 at baseline and by 0.39 after one year ( P <0.05). Conclusions Children s 24 h movement behaviors, particularly physical activity (PA) and sleep, are closely related to children s HRQoL. Appropriate measures should be taken to increase children s PA and SP time and reduce SB time to improve children s HRQoL.

BACKGROUND: Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS: Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS: We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION: The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

ObjectiveTo confirm the clinical efficacy and safety of Yishen Yangxin Anshen tablets in the treatment of insomnia （heart-blood deficiency and kidney-essence insufficiency syndrome）. MethodA randomized block， double-blind， placebo-controlled， multi-center clinical trial design method was adopted， and a total of 480 patients with insomnia due to deficiency of heart blood and insufficiency of kidney essence （treatment group-control group 3∶1） from seven hospitals （Guang'anmen Hospital， China Academy of Chinese Medical Sciences， The First Clinical Hospital， Jilin Province Academy of Traditional Chinese Medicine（TCM）， The Second Affiliated Hospital of Liaoning University of TCM， The First Affiliated Hospital of Henan University of Chinese Medicine， Henan Province Hospital of TCM， Hebei General Hospital， The First Hospital of Hunan University of Chinese Medicine） were enrolled. The treatment group was given Yishen Yangxin Anshen tablets and the control group received placebo tablets （4 tablets/time， 3 times/day， 4 weeks of administration， 4 weeks of follow-up after drug withdrawal）. The sleep dysfunction rating scale （SDRS） score， pittsburgh sleep quality index （PSQI） score， TCM， polysomnography （PSG） indicators from four hospital （Guang'anmen Hospital， China Academy of Chinese Medical Sciences， Henan Province Hospital of TCM， Hebei General Hospital， The First Hospital of Hunan University of Chinese Medicine）， and other efficacy indicators were compared between the two groups before and after treatment. Through general physical examination， laboratory examination， and observation of adverse events， the safety of the drugs was evaluated. ResultThe baseline indexes of the two groups showed no significant difference and thus the two groups were comparable. After treatment， the total score of SDRS in the treatment group was lower than that in the control group （P<0.01）. After drug withdrawal for 4 weeks， the total score of SDRS demonstrated no significant change in the treatment group as compared with that at the end of treatment， indicating that the rebound change of curative effect was not obvious. After treatment， the total score of PSQI in the treatment group decreased as compared with that in the control group （P<0.01）， and the change of total score of PSQI in the treatment group was statistically significant （P<0.05） after drug withdrawal for 4 weeks but small， indicating that the rebound change of curative effect was not obvious. After treatment， the total effective rate about the TCM symptoms in the treatment group was higher than that in the control group （χ²=137.521，P<0.01）. After treatment， the disappearance rates of single indexes in the treatment group， such as difficulty in falling asleep， easily waking up after sleeping， early awakening， short sleep time， dreamfulness， palpitation， forgetfulness， dizziness， mental fatigue， and weakness of waist and knee， increased compared with those in the control group （P<0.01）. After treatment， the treatment group demonstrated fewer awaking times （AT）， longer total sleep time （TST）， lower ATA/TST ratio， and higher sleep efficiency （%） than the control group （P<0.05）. No abnormal value or aggravation related to drugs was observed in either group. The incidence of adverse events in the treatment group and the control group was 5.57% and 8.40% respectively. No serious adverse events or adverse events leading to withdrawal happened in either group. ConclusionYishen Yangxin Anshen tablets is effective and safe for patients with insomnia of deficiency of heart-blood and insufficiency of kidney-essence.

Objective:To collect data on urinary flow rate in the elderly female population across the country and to analyze the range of reference values.Methods:This study enrolled 333 subjects from July 2020 to June 2022.The study implementation process was divided into two steps.In the first step, subjects completed an electronic questionnaire, which included basic information about the subject, a short form for urinary incontinence, and a scoring form for the symptoms of overactive bladder syndrome.In the second step, the staff introduced the use of a mobile uroflowmetric device and distributed the instrument and materials.Uroflow rate data were automatically uploaded to a cloud database via the mobile phone.Subsequently, two or more physicians specializing in urinary control performed Uroflow rate-qualifying screenings and conducted statistical analyses.Results:A total of 333 subjects were enrolled in the study, and the researchers collected 1375 qualified urine flow rate records using a mobile urine flow rate instrument.The age of the subjects ranged from 60 to 84 years, with a mean age of 69 years.The reference ranges for urinary flow rate were found to be 24.8-26.2 s, with a mean urinary flow rate of 12.2-12.9 ml/s, a maximum urinary flow rate of 22.2-23.4 ml/s, and a time to peak of 8.5-9.7 s. The study observed a tendency for both maximal and mean urinary flow rates to decrease in older women as their age increased(Pearson correlation coefficient: -0.1, P<0.001). Conclusions:The uroflow rate of older women decreases with aging.Specifically, the average uroflow rate of women over 80 years old is lower than that of other age groups.This study aims to establish normal uroflow parameters for uroflowmetry in healthy older women in China.

Objective:To analyze the factors influencing the difference in location of cricothyroid membrane between traditional surface palpation and ultrasonic biplane.Methods:One hundred and seven subjects of both sexes, aged 18 yr, underwent neck ultrasound examination in our hospital from August 2021 to December 2021, were selected.The structure of cervical airway was observed by ultrasound.The subjects in whom the structure of cricothyroid membrane was clearly shown were selected.The middle point of cricothyroid membrane was located by otorhinolaryngologist using surface palpation method and by ultrasonic doctor using ultrasonic biplane method.The distance between two positioning points was measured by a ruler.The subjects were divided into accurate group (distance between two points≤3 mm) and difference group (distance between two points>3 mm). The distance between cricoid cartilage and thyroid cartilage (spacing of cricoid cartilage and thyroid cartilage) and distance between the midpoint of cricothyroid membrane and skin (spacing of cricothyroid membrane and skin) were measured by ultrasound.The neck length and the maximum submaxillary distance in head up were measured by a ruler.The factors influencing the difference in location between the two methods were analyzed by multivariate logistic regression.Results:One hundred and four subjects with clear cricoid cartilage and cricothyroid membrane under ultrasound were selected.There were significant differences in the ratio of gender, body mass index (BMI), cricothyroid membrane-skin distance, neck length, and maximum submandibular distance between the two groups ( P<0.05). Multivariate logistic analysis showed that female ( OR=9.091, P<0.001), BMI ( OR=11.214, P=0.001) and increased cricothyroid membrane-skin distance ( OR=5.649, P=0.015) were the factors influencing the difference in location between the two cricothyroid membrane localization methods. Conclusions:Female, obesity (BMI>28.0 kg/m 2) and increased distance between cricothyroid membrane and skin are the factors affecting the difference in location of cricothyroid membrane between ultrasonic biplane method and surface palpation method, and bedside ultrasound is recommended for location in those with the factors mentioned above.

Objective To investigate the effects of shoes type (barefoot, ordinary running shoes, minimalist shoes) and walking speed (jogging, walking at normal speed) on biomechanical parameters of knee joint, so as to provide theoretical reference for scientific fitness. Methods Vicon three-dimensional （3D） motion capture system and Kistler 3D force plate were used to collect biomechanical parameters of lower limbs from 10 subjects during walking at different speed with different shoes. Two-way (2 walking conditions × 3 shoe conditions) repeated measures analysis of variance was used to statistically analyze each dependent variable. Results Compared with jogging, the lateral excursion of plantar center of pressure (COP) was greater, the moment arm in frontal plane, the adduction moment and peak loading rate of knee joint were smaller, but the angular impulse of knee joint in frontal plane was greater. Compared with ordinary running shoes, the stride length was decreased, the lateral excursion of COP was greater, and the moment arm of knee joint in frontal plane, the knee adduction moment, the peak load rate and the angular impulse of knee joint in frontal plane were smaller. Conclusions In order to reduce the angular impulse and peak loading rate of knee joint in frontal plane, it is recommended to jog with small strides for ordinary people with minimalist footwear.

Objective:To analyse the effect of preoperative renal function classification on early outcomes for patients with acute type A aortic dissection(AAAD) and to estimate the risk factors of postoperative major adverse events.Methods:From January 2012 to December 2019, 226 patients with AAAD who underwent total arch replacement at our institution were retrospectively analysed, including 146 males and 80 females, aged(54.4±12.5) years old. Stages of preoperative renal function were defined as follows: Normal[estimated glomerular ltration rate(eGFR)≥90 ml·min -1·1.73 m -2, 68 cases], Mild(eGFR 60-89 ml·min -1·1.73 m -2, 73 cases); Moderate(eGFR 30-59 ml·min -1·1.73 m -2, 57 cases), Severe(eGFR<30 ml·min -1·1.73 m -2, 28 cases). The independent risk factors for postoperative death were analyzed by logistic regression analysis. The area under the receiver operating characteristic curve was used to assess the efficiency of eGFR for predicting the postoperative hemodialysis. Results:In-hospital death occurred in 24(10.6%) cases. Major complications included postoperative hemodialysis in 49(21.7%) cases, stroke in 19(8.4%) cases and tracheotomy in 15(6.6%) cases. The best cut-off value of the eGFR for predicting postoperative hemodialysis was 36.5 ml·min -1·1.73 m -2(area under the receiver operating characteristic curve was 0.793). The following variables were found to be risk factors of in-hospital mortality in multivariate logistic regression analysis: serum creatinine, eGFR<30 ml·min -1·1.73 m -2, neural malperfusion, bowel malperfusion, postoperative stroke and hemodialysis. Conclusion:Total arch replacement can be safely performed in patients with AAAD and mild renal dysfunction. Preoperative renal dysfunction is a risk factor for postoperative hemodialysis, and eGFR is useful for predicting the requirement for hemodialysis after total arch replacement. The severity of preoperative renal dysfunction could greatly influence the outcomes after total arch replacement for AAAD. More importance should be attached to the assessment of preoperative renal function during clinical risk assessment.

Objective:To explore the application effect of the caregiver self-management support project in main caregivers of adolescents with epilepsy.Methods:Using the convenient sampling method, the main caregivers of adolescents with epilepsy who were enrolled before implementation of the caregiver self-management support project of the First Affiliated Hospital of Zhengzhou University from January to August 2019 were included in the control group ( n=101) , and they were given routine follow-up. The main caregivers of adolescents with epilepsy who were enrolled after the implementation of the project from September 2019 to June 2020 were included in the study group ( n=101) . Before and after the intervention, the Connor-Davidson Resilience Scale (CD-RISC) , Simplified Coping Style Questionnaire (SCSQ) , Zarit Burden Interview (ZBI) , Life Satisfaction Index A (LSIA) and Medical Outcome Study Social Support Survey (MOS-SSS) were used to compare the psychological resilience, coping style, quality of life and social support of caregivers between the two groups. Finally, a total of 98 caregivers in the study group and 97 caregivers in the control group completed the study. Results:After the intervention, the scores of dimensions of CD-RISC, positive coping score of SCSQ, LSIA score and dimensions scores of MOS-SSS of main caregivers in the study group were higher than those in the control group, while the scores of negative coping of SCSQ and ZBI were lower than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The caregiver self-management support project helps to strengthen the psychological resilience of the main caregivers of adolescents with epilepsy, enhance their active coping style and social support and improve their quality of life.

Objective:To explore the application effect of narrative nursing in long-term primary family caregivers of maintenance hemodialysis patients.Methods:Using the convenient sampling method, a total of 120 main family caregivers of maintenance hemodialysis patients who received hemodialysis treatment in Hemodialysis Room of a tertiary general hospital were selected as the research objects from May to August 2020. The patients were randomly divided into the observation group ( n=60) and the control group ( n=60) by random number table method. The observation group was given narrative nursing intervention, while the control group was given routine psychological nursing. Zarit Caregiver Burden Interview (ZBI) , Self-rating Anxiety Scale (SAS) and Beck Depression Scale (BDI-Ⅱ) were used to investigate the situation of caregivers in the two groups. Results:Before the intervention, there was no statistically significant difference in the total scores of ZBI, SAS and BDI-Ⅱ between the two groups ( P>0.05) . After the intervention, the total scores of ZBI, SAS and BDI-Ⅱ in the observation group were respectively 23.50 (15.00, 33.00) , 33.00 (27.00, 41.00) and 11.00 (8.00, 14.75) , which were lower than the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Narrative nursing can effectively reduce the long-term care burden of the main family caregivers of maintenance hemodialysis patients and reduce levels of anxiety and depression, which is worthy of clinical application.
