Objective:To investigate the current status of scientific fitness literacy (SFL) and its influencing factors among Chinese adults aged 20-59 years.Methods:Totally 63 338 adults aged 20-59 years in the status of national fitness activities in 2020 from 1 January to 31 March 2020 were selected as the subjects, and they were divided into four age groups, namely, the 20-29 age group, the 30-39 age group, the 40-49 age group and the 50-59 age group. Data were analyzed by SPSS 29.0.Comparative analyses for age, gender, urban-rural difference were carried out by applying non-parametric tests, and multiple regression models were applied to find the influencing factors of SFL.Results:The SFL score of Chinese adults aged 20-59 years was 53.40 (41.67, 63.73), and the scores of cognition, attitude, ability and skills, behavior and habits sub-dimensions were 86.11 (72.22, 100.00), 62.96 (50.62, 75.31), 27.78 (11.11, 44.44) and 33.33 (11.11, 55.56), respectively. The SFL and the four sub-dimensions were demonstrated to have higher scores for males than females, and higher scores for adults in urban area than those in rural area(all P<0.01). The multiple regression results showed that regular exercise at a fitness facility (20-29 age group: β=0.321, t=5.940, P<0.01; 30-39 age group: β=0.187, t=2.937, P<0.01; 40-49 age group: β=0.230, t=3.988, P<0.01; 50-59 age group: β=0.415, t=5.671, P<0.01) was the Chinese adults' common influence factor on SFL.Motivation, evaluation by those around them, experience from exercising, and convenience and atmosphere of exercising were the main influence factors in the 20-29 and 30-39 age groups(all P<0.05).Comfort level of fitness venue, convenience, safety, and support of fitness place were the main influence factors in adults aged 40-59 years(all P<0.05). Conclusions:Chinese adults aged 20-59 years old have high SFL awareness scores, but low overall SFL scores. Surrounding people's evaluation, experience in exercise, comfort level of fitness place, convenience, safety and fitness policy support are the influential factors of scientific fitness literacy.

Objective The purpose of this study is to explore the effects of reminazolam and midazolam on the occurrence of deliri-um in postoperative patients with congenital heart disease.Methods A total of 131 postoperative patients with congenital heart disease were admitted to our hospital from March to August 2023,they were randomly divided into a reminazolam group(n=66)and a midazolam group(n=65).The Cornell Delirium Assessment Scale for Children was used to evaluate postoperative delirium.We analyzed and com-pared the incidence,occurrence time,and duration of the two groups.We also recorded the patient's adverse drug reactions,mechanical ventilation time,cardiac intensive care unit(CICU)stay time,and hospitalization time.Results The incidence of delirium was 51.7％in the midazolam group and 40.0％in the reminazolam group,with no statistically significant difference.However,there were significant differences in the timing of delirium occurrence between the two groups(x2=12.400,P=0.030).The duration of delirium in the remi-nazolam group was significantly shortened(x2=14.773,P=0.034).There was no statistically significant difference between the two groups in mechanical ventilation and CICU retention time.There was a difference in hospitalization time between the two groups(z=0.096,P=0.016).There were 2 cases of adverse reactions(3.08％)in the midazolam group and 5 cases(7.58％)in the reminazolam group,with no statistically significant difference.Conclusion As a benzodiazepine drug,reminazolam has a certain protective effect on postoperative delirium in patients undergoing congenital heart surgery.However,further research is needed on the application of reminazo-lam in children,including drug dosage and adverse reactions.

Objective:To develop a prone position management program and evaluate its effectiveness in preventing ventilator-associated pneumonia (VAP) in children with congenital heart disease combined with acute respiratory distress syndrome, in order to provide experience for clinical application.Methods:This was a quasi-experimental study. Convenient sampling method was used to select children with congenital heart defect who underwent mechanical ventilation in the Cardiothoracic Surgical Care Unit of Shanghai Children′s Medical Center, Shanghai Jiao Tong University, School of Medicine from June 2018 to December 2021 as the study subjects. The control group consisted of 80 hospitalized children from June 2018 to December 2019. They were used general nursing interventions to prevent VAP. The 42 hospitalized children from January 2020 to December 2021 were the intervention group, who usd the prone position management program on the basis of the control group. The differences in the incidence of VAP, duration of mechanical ventilation, duration of ICU stay, oxygenation index and the incidence of adverse events between the two groups were compared.Results:The incidence of VAP and mechanical ventilation duration in the intervention group were 4.8% (2/42) and 67.50 (55.00/101.50), which were lower than 35.0% (28/80) and 92.50 (68.00/142.00) of the control group, and the differences were statistically significant ( χ2=11.98, Z=3.40, both P<0.01). And the trend of increasing oxygenation index with the intervention group was better than the control group ( F=8.38, P<0.05). There was no statistical difference in the incidence of adverse events between the two groups (all P>0.05). Conclusions:The application of prone ventilation program with congenital heart disease children complicated with acute respiratory distress syndrome is safe and can significantly improve the oxygenation index, shorten the duration of mechanical ventilation and reduce the incidence of VAP.

Mast cells, autoantibodies, inflammatory cells, coagulation cascade, complement system and nervous system are all involved in the complex pathogenesis of chronic spontaneous urticaria (CSU) , while mast cells play a pivotal role in it. With deeper understanding of the pathogenesis of CSU, cutting-edge therapeutic methods are gradually being used in clinical practice. Nowadays, pharmacotherapyeutic studies are more focused on accurately modulating the pathological state of mast cells. This review summarizes recent advances in the pathogenesis of and medicines for CSU.

Objective:To explore the situation and characteristics of the practice of severe cardiac analgesia, sedation and delirium in children in China, so as to lay a research foundation for standardizing the prevention process of severe cardiac analgesia, sedation and delirium in children.Methods:This study was a cross-sectional study, using questionnaire survey. The Analgesia, Sedation and Delirium Practice Questionnairewas designed according to consensus, clinical suggestions and clinical practice. In August 2021, the electronic questionnaire was issued to the Children's Cardiac Intensive Care Unit (ICU) in children's hospitals through the Pediatric Nursing Alliance Pediatric Congenital Nursing Group of the National Children's Medical Center. A total of 15 ICUs were included, all of which completed the survey, and the effective recovery rate of the questionnaire was 100%.Results:The 15 ICUs all had pain assessment system, including 11 with pain assessment standard operating procedures, 8 with sedation assessment standard operating procedures, and 4 with delirium assessment. However, there was no specific process or system for delirium assessment in ICU. All 15 ICUs used analgesics, 8 of them used opioids for analgesia immediately after cardiac surgery, 5 of them used analgesics according to the patient's condition, 2 of them used analgesics according to the pain score. Non-steroidal paracetamol was the first choice for non-postoperative children, and 6 of 15 ICUs used analgesics according to the pain score. All 15 ICUs used sedative drugs, 6 of which used sedative drugs within 1 hour after admission, 6 of which were decided by the doctor according to the situation of the child, 3 of which used sedative drugs according to the sedation score, and 7 of which used midazolam as the first choice. A total of 6 the 15 ICUs carried out some projects in the "ABCDEF" delirium prevention program.Conclusions:In this investigation, the use of analgesic and sedative drugs in ICU is heterogeneous, the evaluation process of analgesia and sedation has not been established, and delirium has not attracted enough attention. Rational sedation and analgesia need to develop standardized sedation and analgesia evaluation procedures. At present, high-quality clinical studies are still needed to provide data support for the construction of standardized processes.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Traditional Chinese medicine (TCM) has played a pivotal role in maintaining the health of Chinese people and is now gaining increasing acceptance around the global scope. However, TCM is confronting more and more concerns with respect to its quality. The intrinsic "multicomponent and multitarget" feature of TCM necessitates the establishment of a unique quality and bioactivity evaluation system, which is different from that of the Western medicine. However, TCM is investigated essentially as "herbal medicine" or "natural product", and the pharmacopoeia quality monographs are actually chemical-markers-based, which can ensure the consistency only in the assigned chemical markers, but, to some extent, have deviated from the basic TCM theory. A concept of "quality marker" (Q-marker), following the "property-effect-component" theory, is proposed. The establishment of Q-marker integrates multidisciplinary technologies like natural products chemistry, analytical chemistry, bionics, chemometrics, pharmacology, systems biology, and pharmacodynamics, etc. Q-marker-based fingerprint and multicomponent determination conduce to the construction of more scientific quality control system of TCM. This review delineates the background, definition, and properties of Q-marker, and the associated technologies applied for its establishment. Strategies and approaches for establishing Q-marker-based TCM quality control system are presented and highlighted with a few TCM examples.

Objective Patients with single-ventricle physiology pose a wide variety of therapeutic challenges.Pulmonary artery or anastomosis stenosis in single-ventricle physiology will have only subtle hemodynamic derangements due to the lack of the pumping chamber to force blood across the stenosis.This study aimed to evaluate the feasibility and usefulness of the stent implantation for treatment of branch pulmonary artery and anastomosis stenosis in children with univentricular hearts.Methods Retrospective analysis of 8 implanted stents between March 2014 and January 2015 in Shanghai Children's Medical Center.Transthoracic echocardiography,chest roentgenography and electrocardiography were carried out as follow-up studies at the second day after operation and 1,3,6,12 months after the procedure.Results In all of eight patients (6 males and 2 females),5 cases were post-Glenn operation and 3 cases were post-Fontan operation.The median age was 6.6 years (range 4.0-8.5 years).The median weight was 19.5 kg(range 13.8-25.6 kg).9 stents were implanted successfully in all patient,6 in left pulmonary arteries,2 in right pulmonary arteries and 1 in anastomosis.All stents were placed in the target lesion without any complication.The diameter of the narrowed segment improved from (3.63 ± 2.06) mm to (7.89 ± 1.62) mm (P ＜ 0.01).During follow-up no other complication occurred except thrombus in one patient because of discontinuation anticoagulation.Conclusion Branch pulmonary arterial stenosis in single-ventricle patients may often be underestimated due to the low pressure venous system and/or the development of venovenous collaterals bypassing and decompressing the pulmonary circuit.In these patients,even mild stenosis should be treated aggressively,especially in the presence of pleural effusions,pericardial effusions,protein-losing enteropathy and low-output states.Stent implantation is an effective method of treating branch pulmonary artery stenosis.

OBJECTIVEThe Pul-stent is a new cobalt alloys stent, specially licensed for pulmonary artery stenosis. The aim of this study was to investigate the value of the stent implantation as the treatment of postoperative pulmonary artery stenosis.

METHODClinical practice was carried out to evaluate effectiveness, safety and maneuverability of Pul-stent in the defined clinical setting. Transthoracic echocardiography, chest roentgenography and electrocardiography were carried out as follow-up studies at 1 and 3 months after procedures.

RESULTTen patients (7 males and 3 females) received Pul-stent implantation in left or right pulmonary arteries (9 stents in left and 1 stent in right). For 9 cases transcatheter stent implantation was performed and in I case hybrid procedure. The median age was 7. 9 years (range 3. 4 - 13. 7 years). The median weight was 22. 3 kg (range 13 - 32 kg). Among them 6 cases were post surgical repair of tetralogy of Fallot, 2 cases were after Fontan procedures, 1 patient was post surgical repair of pulmonary atresia with ventricular septal defect, and 1 patient had stenosis at Glenn pathway. The pressure gradient at the stenosis decreased from (31. 6 ± 10. 2) mmHg(1 mmHg =0. 133 kPa) to (7. 3 ± 10. 3) mmHg, and the diameter of the narrowest segment increased from (4. 0 ± 2. 3) mm to (9. 6 ± 2. 7) mm, the right ventricle to aortic pressure ratio decreased from 0. 54 to 0. 36, all of these improvements were statistically significant (t = 3. 9, -9. 7, 4. 5; P =0. 008, 0. 000, 0. 004). The total procedure time ranged from 55 to 220 min (median 117 min) , and the fluoroscopy time ranged from 9 to 67 min (median 26 min). There were 2 cases of post-stenting pneumorrhagia. No stent fracture, stent malposition and other severe complications were observed. Initial follow-up of 1 and 3-months showed good results with maintenance of improved caliber of the stented vessel, and the gradient across the stenosis area measured by echocardiography was (32. 0 ± 14. 6) mmHg after 3 months. Compared with before stentifng ((40.6 ± 15. 2) mmHg) and 1 month later ((30. 6 ± 13. 6) mmHg), the difference was not statistically significant (t =2. 2,1. 76; P =0. 07, 0. 10).

CONCLUSIONPul-Stent tracking and delivery was excellent, the initial experience has shown that Pul-stent implantation was effective and safe in treating post-operative branch pulmonary artery stenosis. Further follow-up study should be conducted to make sure whether those good results would be kept constant.
