Background and Objective Organ transplantation has become an essential and irreplaceable treatment for patients with organ failure. Although organ transplantation was introduced to China in the 1960s, it has witnessed rapid development in recent years. However, problems have been identified in the course of its development. We aim to present both medical and legal points of view on organ transplantation, to compare the current status of organ transplantation in China with that in developed countries, and discuss the challenges China faces in developing its own legislation for organ transplantation. Methods We searched the websites of WHO, NIH, AST, UNOS, and governments, as well as relevant conference proceedings and expert consensus documents. Articles or documents involving organ transplantation legislation were identified. Results We included 10 legal documents, 1 regulation, 9 government documents, and 4 expert consensus documents. Organ transplantation legislation started in the 1960s in the United Kingdom, and was soon followed by New Zealand and the United States. The first law on brain death was enacted in the United States in 1978. Since 1991, the World Health Assembly (WHA) and other non-governmental organizations have issued 7 consensus documents in order to regulate behaviors related to organ transplantation. China including Hong Kong, Macau and Chinese Taipei has not yet formulated any law on organ transplantation. Conclusion At least six challenges about organ transplantation and brain death legislation in China are identified: ① death definition and source of organ donors; ② prevention of organ transplant tourism; ③ risk assessment and insurance for living donors; ④ defining who has the right to choose about potential organ donation for an individual: whether spouses, parents, or children; ⑤ whether an organ donor should receive compensation; ⑥ whether brain death and organ transplant laws should be formulated separately.
Enhanced recovery after surgery (ERAS) has been carried out in many surgical fields such as orthopedics, galactophore, cardiothoracic surgery, gastrointestinal surgery, and obstetrics due to its standardized perioperative management process to reduce surgical stress and reduce surgical complications. After more than a decade of development, ERAS has achieved initial results. However, in China, the development of ERAS in orthopedic is still in its infancy. Most of the researches focus on the multidisciplinary management path of perioperative period. How to break through the existing bottlenecks is the key to accelerate the further development of rehabilitation. Therefore, this paper introduces the origin and development of ERAS, analyzes the challenges and opportunities of orthopedic ERAS in clinical advancement, proposes the important measures to promote the accelerated development of orthopedics, and provides new ideas for promoting the in-depth development of orthopedics accelerated rehabilitation.
ObjectiveTo investigate the role of interleukin-25 (IL-25) and its receptor during allergen challenge test in allergic asthmatics as well as its underlining mechanism.MethodsFifteen allergic asthmatic patients with dual response in allergen challenge test were enrolled and blood samples were collected before and after challenge test. The expression levels of IL-25 receptor on the surface of eosinophils, plasma and intracellular IL-25 levels were measured by flow cytometry and enzyme-linked immunosorbent assay. Besides, the function of eosinophils from these patients was evaluated through the expression of type 2 cytokines, degranulation and chemotaxis after stimulation with IL-25.ResultsUpon allergen challenge, the expression of IL-17RB on the surface of eosinophils were increased from (7 426±2 824)/106 white blood cells to (19 446±5 593)/106 white blood cells (P<0.001). The expression of IL-17RA/RB on eosinophils were significantly increased from (4 508±1 360)/106 white blood cells to (9 025±3 166)/106 white blood cells (P<0.001). The plasma level of IL-25 increased from (650±45) pg/ml to (851±43) pg/ml (7 hours after allergen challenge) and (813±56) pg/ml (24 hours after allergen challenge) (P<0.001). The intracellular IL-25 expression of eosinophils was also upregulated from (10 398±1 909)/106 white blood cells to (147 684±46 222)/106 white blood cells (P<0.05). In vitro study, IL-25 (1 ng/ml) stimulated eosinophils for 2 hours promoted its expression of peroxidase [(12.5±4.2) ng/ml compared to control (1.26±0.4) ng/ml, P<0.05). The intracellular expression of IL-5 and IL-13 in eosinophils were also increased after stimulated by IL-25. IL-25 (1 pg/ml) stimulation compared to control could increase eosinophil migration in eotaxin [(36±3) vs. (69±5), P<0.05).ConclusionIL-25 and its receptor play a critical role in eosinophilic aggregation, activation and mobilization during allergic inflammation in allergic asthmatics.
ObjectiveTo evaluate the predictive value of mini-fluid challenge for volume responsiveness in patients under shock.MethodsSixty patients diagnosed as shock were included in the study. A 50 mL infusion of physiological saline over 10 seconds and a further 450 mL over 15 minutes were conducted through the central venous catheter. Cardiac output (CO), global end-diastolic volume index (GEDVI), central venous pressure (CVP) and extravascular pulmonary water index (EVLWI) were monitored by the pulse indicator continuous cardiac output monitoring. If the increase of CO after 500 mL volume expansion (ΔCO500) ≥10%, the patient was considered to be with volume responsiveness. The relevance between ΔCO50 and ΔCO500 was analyzed, and the sensitivity and specificity of the ΔCO50 were analyzed by receiver operating characteristic (ROC) curve.ResultsAfter 50 mL volume injection, the heart rate and systolic blood pressure of the two groups did not change obviously. The CVP of non-responders changed slightly higher than that of responders, but neither of them had obviously difference (P>0.05). The CO of responders had increased significantly (P<0.05) which was in accord with that after a further 450 mL volume injection. GEDVI and EVLWI did not change significantly (P>0.05). ΔCO50 and ΔCO500 were strongly correlated (r=0.706, 95%CI 0.677 - 0.891, P>0.05). The area under ROC curve for ΔCO50 was 0.814 (95%CI 0.707 - 0.922).ConclusionThe volume responsiveness of patients under shock can be predicted by mini-fluid challenge study which is related to normal volume expansion and it does not increase the risk of pulmonary edema.
Brain-computer interface (BCI) can be summarized as a system that uses online brain information to realize communication between brain and computer. BCI has experienced nearly half a century of development, although it now has a high degree of awareness in the public, but the application of BCI in the actual scene is still very limited. This collection invited some BCI teams in China to report their efforts to promote BCI from laboratory to real scene. This paper summarizes the main contents of the invited papers, and looks forward to the future of BCI.
After more than 30 years of localized development of infection prevention and control in China, a prevention and control system in line with China’s conditions has been established. Since the coronavirus disease 2019 pandemic began, with the unprecedented attention paid to healthcare associated infection by health administrative departments at all levels, the awareness of infection prevention and control of various personnel has been continuously strengthened, which has promoted the cross-integration and development of infection prevention and control-related disciplines. However, under the normalized pandemic prevention and control, infection prevention and control work also faces enormous pressure and challenges. This paper summarizes the opportunities for infection prevention and control in the new era, analyzes the current challenges in the field of infection prevention and control, and aims to provide some ideas for the future development of infection prevention and control.

Decision-making is often a complex and hard-to-routinize process. Based on the decision-making experience of fighting COVID-19, policymakers have gradually realized that climate action, quality education, and other societal challenges, as well as the sustainable development goals (SDGs) need to be addressed with the best available evidence using an evidence-informed decision-making (EIDM) approach. The Global Commission on Evidence was established in 2021. In addition, the Evidence Commission issued reports in 2022 and 2023. A systematic methodology to address societal challenges with EIDM has been constructed in the report. Five types of domestic evidence (data analytics, evaluation, modeling, qualitative insights, and behavioural/implementation research) and four steps in decision-making process (understanding a problem and its causes, selecting an option for addressing the problem, identifying implementation considerations, and monitoring implementation and evaluating impacts) were used to support four types of decision-makers (government policymakers, organizational leaders, professionals and citizens) in EIDM, as demonstrated by the reports. To further disseminate the concept and methodology of EIDM globally, the secretariat works with 25 Evidence Commissioners to write the report, and continues to cooperate with Country Leads Group from 12 countries to conduct rapid evidence-support system assessments (RESSAs), and collaborates with Evidence Commission Implementation Council to accelerate the implementation of 24 recommendations. The main history, core methodology, and latest developments of the Global Committee on Evidence were systematically reviewed in this paper. We aimed to show decision-makers a new version of how to scientifically address the societal challenges of EIDM.
With nearly four decades of progress in healthcare-associated infection prevention and control in China, the national quality control efforts in this field have been ongoing for the past ten years, advancing rapidly with significant achievements. Over the last decade, the team of infection control professionals involved in quality management and control in China has consistently expanded, accompanied by an enhancement of their skills. Management capabilities have steadily grown, and operational mechanisms have been continuously refined. As public hospitals transition into a new phase of high-quality development, emphasizing refined management models and intrinsic development of medical quality, it becomes crucial to further fortify the foundation and foster innovation in infection control work to ensure quality. This article provides an overview of the establishment and implementation of the National Center for Quality Control of Infection Prevention and Control, examines the current shortcomings and challenges in the field, and collectively explores the positioning and direction of the development of quality control efforts for infection prevention and control in China.
