Objective To investigate the current status of acceptance of disability(AOD)among young and middle-aged spinal cord injury patients and analyze the factors influencing it,in order to provide a basis for nursing managers to develop targeted interventions.Methods From February to July 2024,a convenience sample of 330 young and middle-aged spinal cord injury patients who were hospitalized in 3 tertiary-level hospitals in Henan Province was selected.The survey was conducted using a general information questionnaire,the Brief Adaptation to Disability Scale-Revised,Perceived Social Support Scale,Connor-Davidson Resilience Scale-10 item,Brief Illness Perception Questionnaire,Medical Coping Modes Questionnaire.Results A total of 322 patients were included in the final analysis,yielding a valid response rate of 97.58％.The AOD score for young and middle-aged spinal cord injury patients was(25.99±6.68).Multiple linear regression analysis revealed that gender,education level,type of paralysis,injury duration,pain intensity,social support,psychological resilience,disease perception,and coping styles(confrontation and submission)were influencing factors of AOD(P＜0.05).Conclusion AOD among young and middle-aged spinal cord injury patients is at a moderate level.Healthcare professionals should pay particular attention to male patients,those with low literacy,quadriplegia,shorter injury durations,high pain intensity,low social support,weak psychological resilience,strong disease perception,and yielding coping styles.Timely interventions are recommended to enhance AOD,strengthen rehabilitation outcomes,and improve prognosis.

Objective To investigate the conformational states of ADAMTS13 under different pH conditions.Methods Atomic force microscopy(AFM)was applied to pull ADAMTS13 molecules with two distinct pulling systems:the Biotin-Streptavidin system and the 6×His-Anti-His antibody system.The rupture forces and molecular contour lengths were analyzed.Results Under pH 7.4 condition,when ADAMTS13 was pulled by Biotin-Streptavidin system,the mean molecular contour length was(30.93±1.56)nm,exhibiting a bimodal frequency distribution with peak positions at(22.12±0.01)and(49.57±0.05)nm.When ADAMTS13 was pulled using 6×Hist-anti-His antibody system,the mean molecular contour length was(32.77±0.72)nm,also showing a bimodal distribution,with a peak position at(25.73±0.16)and(43.84±0.63)nm,respectively.Under pH 6.0 condition,when ADAMTS13 was pulled by Biotin-Streptavidin system,the mean molecular contour length increased to(47.07±1.6)nm,and the frequency distribution shifted to trimodal,with peak positions at(22±1.25),(55.09±2.62)and(76.69±3.06)nm.The conformation of ADAMTS13 was more extended at pH 6.0 compared with that at pH 7.4.Conclusions ADAMTS13 exists in'closed'and intermediate conformational states at physiological pH 7.4.However,at pH 6.0,ADAMTS13 can adopt'closed',intermediate,and'open'conformational states.This study contributes to a further understanding of the role of ADAMTS13 in normal physiology and thrombotic thrombocytopenic purpura,providing insights for the development of novel recombination ADAMTS13 drugs.

  Objective  To promote the development of high-quality health standards in China and summarize the characteristics of global health standards management systems and development processes.  Methods  We conducted a systematic search of relevant databases and the websites of standardization institutions. A descriptive method was used to analyze the basic characteristics of the standard management systems and development processes.  Results  The majority of the investigated countries and organizations primarily implement voluntary standards, with the exception of Chinese and the European Committee for Standardization that enforce compulsory standards. All countries and organizations have health standards at the national, group, and enterprise levels. In China and Japan, standards authorities are subordinate to the government, while in other countries or organizations, they operate as independent civil societies. The development process for health standards generally involves five stages: "Project/Proposal → Draft → Enquiry → Review → Publication". However, the specific steps in the development of health standards vary across different countries and organizations. Furthermore, China ranks high in the number of both standards and health standards issued, but the proportion of health standards is only 2.06%.  Conclusions  There are significant differences between China and other countries in terms of the management system and development process of health standards. To promote the management and development of high-quality health standards in China, we recommend promoting the coordination mechanism for standard development, increasing efforts to publicize standards and evaluate the implementation effect, strengthening the construction of personnel for the development of health standards, optimizing the efficiency of standard development and improving the internationalization level of health standards.

National health standards involve all kinds of technical requirements formulated and numbered in accordance with the procedures and formats stipulated in the standardisation system for the implementation of national health and hygiene laws, regulations and policies, and the protection of human health. The establishment of health standards in China should align with our legal framework, including laws, regulations, departmental rules, and health and hygiene policies. During the development of these standards, a comprehensive approach is advocated, encompassing in-depth investigations, rigorous demonstrations, and extensive stakeholder engagement. However, the process of standard formulation may suffer from insufficient research evidence. The evidence-based concept emphasizes the significance of evidence. Therefore, integrating evidence-based concept into the process of developing health standards can enhance the quality and scientific basis of these standards. This article systematically elucidates the current status and development process of health standards in China, explores the necessity and feasibility of incorporating evidence-based concept into the development of these standards, analyzes the challenges and opportunities, and presents reflections and suggestions.

OBJECTIVE： To evaluate the medication of elderly inpatients receiving multiple medication， to evaluate the effects of pharmaceutical care provided by clinical pharmacists， and to provide reference for clinical drug use of elderly patients. METHODS： The elderly inpatients receiving multiple medication were selected from Beijing Friendship Hospital Affiliated to Capital Medical University during Oct. 2018 to Feb. 2019. The process of pharmaceutical care for elderly inpatients was established and developed through the CGA team of the elderly. PCNE classification system was used to analyze drug-related problems； Bayliff tool was used to evaluate the harmfulness of drug-related problems； Morisky questionnaire was used to analyze medication compliance. Drug use was followed up 3 months after discharge to evaluate the effect of clinical pharmacist’s intervention. RESULTS： A total of 71 elderly inpatients with multiple medication were included， 73.24％ of them （52 patients） suffered from 54 drug-related problems， 32 of which were related to therapeutic effects （59.26％）， 13 （24.07％） drug adverse events （possible）， 9 unnecessary drug therapy problems （16.67％）. There were 69 causes of pharmaceutical related problems， of which 58 （84.06％） were doctor’s orders. The main causes were drug selection （36.23％）， drug dosage （24.64％） and drug dosage form （20.29％）. Totally 143 interventions were conducted by clinical pharmacists， including 102 successful interventions， with success rate of 71.33％. The highest acceptance of intervention was adverse drug events reporting（100％）， followed by patient level （97.56％）， doctor level （65.12％） and drug level （52.83％）. Among 54 pharmaceutical-related problems， the most potential hazards were grade 1 hazards， involving 35 problems （64.81％）. The score of medication compliance in patients who received medication education from clinical pharmacists was （6.19±0.58）， which was significantly higher than （4.13±1.62） at the initial stage of admission （P＜0.05）. Follow-up results showed that 6 patients discontinued drugs by themselves， and 13 patients took drugs additionally by themselves. CONCLUSIONS： Drug related problems were common in elderly inpatients receiving multiple medication. Clinical pharmacists can establish a feasible pharmaceutical care process suitable for clinical needs according to the actual clinical situation. With the help of relevant evaluation tools such as relevant drug criteria， drug instructions and drug software， and at the same time， according to the physiological and pathological conditions of patients， they can cooperate with clinicians to select suitable therapeutic drugs for elderly patients to reduce the phenomenon of unreasonable medication and multiple medication， so as to improve the effectiveness and safety of drug use in the elderly.
