ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

ObjectiveTo explore the potential mechanism of moxibustion at Guanyuan (CV 4) in delaying skin photoaging. MethodsThirty-two male Wistar rats were randomly divided into four groups, namely blank group, model group, vitamin E group, and moxibustion group, with 8 rats in each group. Except for the blank group, dorsal skin of rats were exposed to ultraviolet (UV) radiation to establish a skin photoaging model. One week after modeling, the moxibustion group received moxibustion at "Guanyuan (CV 4)" once a day, five days per week; the vitamin E group received vitamin E (25 mg/kg·d) once a day by gavage, five days per week; the blank group, model group, and moxibustion group received an equivalent volume of normal saline via gavage; the intervention lasted for 7 weeks. After 7 weeks, dorsal skin tissues were collected to analyze the following indicators, such as skin tissue moisture content, histomorphological changes using hematoxylin-eosin (HE) staining, Collagen Ⅰ and collagen Ⅲ content using ELISA. Malondialdehyde (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), hydrogen peroxide (H2O2), and catalase (CAT) activity in skin tissue were dectected. Western Blot was used to determin autophagy-related proteins, including microtubule-associated protein 1A/1B-light chain 3 (LC3), polyubiquitin-binding protein (p62), and autophagy-specific gene (Beclin-1); LC3, p62, and Beclin-1 mRNA expression was detected via qRT-PCR, and autophagosome formation was observed using transmission electron microscopy (TEM). ResultsHE staining showed that the epidermal structure in the blank group was orderly and evenly thick, while the model group exhibited uneven epidermal thickness. In the moxibustion group, the epidermis was well-structured, smooth, and uniform, with densely arranged dermal layers; the epidermis in the vitamin E group was thicker than that in the model group. Compared with the blank group, the model group exhibited decreased skin moisture content and reduced level of Collagen Ⅰ and collagen Ⅲ, reduced SOD, CAT, and GSH-Px activity in skin tissue, increased H2O2 and MDA activity, elevated p62 protein and mRNA expression, reduced LC3 and Beclin-1 protein and mRNA expression (P<0.05 or P<0.01). Compared with the model group, the moxibustion group showed significant improvement in all these indicators (P<0.05 or P<0.01); whereas the vitamin E group did not show a statistically significant difference in Collagen Ⅰ and collagen Ⅲ levels (P>0.05). TEM results showed that, compared with the blank group, the model group had atrophic skin cells, extensive mitochondrial vacuolization, and degraded cellular structures; the moxibustion group exhibited crescent- or cup-shaped autophagosomes with a significantly increased number of autophagosomes per unit area, whereas the vitamin E group showed less improvement than the moxibustion group. ConclusionMoxibustion at "Guanyuan (CV 4)" may alleviate skin photoaging by regulating oxidative stress imba-lance, modulating cellular autophagy, and promoting collagen synthesis, thereby slowing the aging process of the skin.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza, and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter, prospective, non-randomized, parallel, controlled trial was conducted from October 2021 to May 2022 in five hospitals, including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness (ILI) cases were collected, and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention, they were assigned to the observation group (108 cases) or the control group (108 cases). Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine (TCM) symptom score scale for influenza, influenza-related emergency (outpatient) visit rate, influenza hospitalization rate, and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled, with 108 in the observation group and 108 in the control group. Primary outcomes: (1) Incidence of ILI: The incidence was 12.0% (13/108) in the observation group and 23.1% (25/108) in the control group, with the observation group showing a significantly lower incidence (χ2=4.6, P<0.05). (2) Influenza confirmation rate: 3.7% (4/108) in the observation group and 4.6% (5/108) in the control group, with no statistically significant difference. Secondary outcomes: (1) TCM symptom score scale: after onset, nasal congestion and runny nose scores differed significantly between the two groups (P<0.05), while other symptoms such as fever, sore throat, and cough showed no significant differences. (2) Influenza-related emergency (outpatient) visit rate: 84.6% (11 cases) in the observation group and 96.0% (24 cases) in the control group, with no significant difference. (3) Time to onset after exposure: The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group, with a statistically significant difference (P<0.05). ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions, Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Objective To analyse the crude detection rate and trends of newly detected HIV/AIDS cases in medical institutions in China from 2017 to 2023, and to provide a reference for optimizing HIV testing strategies in medical institutions. Methods Data on HIV testing and newly reported HIV/AIDS cases were analysed using data from the Comprehensive AIDS Prevention and Control Information System of the China Information System for Disease Control and Prevention for the period from 2017 to 2023. HIV testing in medical institutions includes patients tested preoperatively, those tested before transfusion, those tested in sexually transmitted disease (STD) clinics, prenatal care clinics, and other types of patients. Descriptive statistical analysis and χ2 test were performed using SAS 9.4 software. Joinpoint regression was performed using Joinpoint 4.9.0 software to analyse trends of the crude detection rates over time. Results From 2017 to 2023, the person-times of HIV tests in medical institutions increased from 143 million to 255 million, with an increase of 78.07%. The number of newly detected HIV/AIDS cases increased from 74 000 to 88 000 and then declined to 69 000. The crude detection rate of new HIV/AIDS cases declined from 5.18/10 000 to 2.71/10 000, showed a declining trend, the mean annual percentage change was -9.99%(P<0.001). The crude detection rate of new HIV/AIDS cases in STD clinics was the highest among all types of clinic visits (12.79/10 000-24.47/10 000), and the crude detection rate of new cases among all types of clinic visits showed a decreasing trend(P<0.05). Among different medical institutions, general hospitals were the most important source of the number of tests and the number of newly detected HIV/AIDS cases, accounting for more than 62.93% and 62.68%, respectively. Specialised medical institutions had the highest crude detection rate of new cases, which was maintained at more than 5.13/10 000. The crude detection rate of new cases for all four types of medical institutions, except for primary medical institutions, showed a decreasing trend (P<0.05). Conclusions The detection rate of new cases in medical institutions showed a decreasing trend in 2017-2023, and the efficiency of STD clinics testing and detection was higher among all types of attendees. General hospitals are the main source of new cases detection, and testing in specialised medical institutions is more efficient. Testing should be strengthened in key groups of patients and in key medical institutions.

Globally, over 300 million surgeries are performed each year, and more than 50% of surgeries involve patients aged 65 and older. Aging poses significant challenges to perioperative brain health, as the deterioration of brain structure and function increases susceptibility to postoperative neurological complications. Protecting perioperative brain health remains a worldwide clinical challenge. With senescence, the brain undergoes a progressive decline in homeostasis across various molecular, cellular, and regional functions. Anesthetics and surgical stimuli may accelerate the disruption of brain homeostasis and exacerbate age-related neurodegeneration. This review provides a framework for understanding how anesthesia and surgery can affect brain health in the aging population and contribute to postoperative neurological complications, with a particular focus on perioperative neurocognitive disorder.

Objective: To investigate the basic situation of pre-analytical quality management in blood station laboratories in North China, and to provide baseline data for promoting the homogenization and standardization of these pre-analytical processes in each blood station laboratory. Methods: A cross-sectional status survey was designed based on the quality management regulations of blood stations, ISO15189 standards and relevant quality management requirements. This survey covering various aspects including laboratory general situation, sample collection and temporary storage, transportation, reception, and quality continuous improvement situations. Data analysis was performed on the survey results of each laboratory. Results: All the 38 blood station laboratories in North China had established a pre-analytical quality management system framework and implemented basic pre-analytical quality control activities; however, there were differences in implementation. 1) Among the 12 basic quality items, 3 items were monitored by all the investigated laboratories (100%), 6 items were monitored by the vast majority of laboratories (about 90%), and 3 items were monitored by a portion of laboratories (about 60%). There were no significant differences in the monitoring index among the three regions and among different types of laboratories (P>0.05). 2) Among the total of 26 items in the three key processes before testing (sample collection and storage, transportation, reception and processing), 12 items were monitored by all laboratories (100%), 11 items were monitored by the vast majority of laboratories (about 90%), and 3 items were monitored by a portion of laboratories (about 75%). There were no significant differences in monitoring index among different regions and types of laboratories (P>0.05). Conclusion: This survey provides a reference and basis for the gap analysis of the pre-analytical process quality management in 38 blood station laboratories across North China. It facilitates laboratories in identifying pre-analytical quality problems, resolving problems, preventing errors, and ensuring that the quality of blood samples before testing meets the established requirements. It lays a foundation for the homogenization of pre-analytical quality management in regional blood stations.

Objective: To investigate the assessment criteria and subsequent handling practices of hemolytic and lipemic blood samples before testing in blood screening laboratories in North China, and to provide data to support the standardization of their management in blood station laboratories. Methods: Data on the preanalytical management of hemolytic and lipemic samples from 38 laboratories were collected. The details of management on the criteria and verificatioon for assessment, the assessment methods, and subsequent handling procedures of hemolytic and lipemic samples in blood station laboratories were analyzed. Results: 1) All 38 blood station laboratories monitored serological and nucleic acid samples for hemolysis and lipemia in pre-analytical phase. 2) The criteria and methods for assessing hemolytic and lipemic samples varied among the laboratories of the 38 blood stations. 15 laboratories (39.47%) followed manufacturer's instructions, 9 laboratories (23.68%) formulated their own criteria, and 14 laboratories (36.84%) referred to the criteria of other laboratories. 16 laboratories (42.11%) verified the criteria for assessing hemolytic and lipemic samples, with significant variations in verification rate across laboratories from different regions (P<0.05). For the assessment methods, visual inspection was used by 28 laboratories (73.68%) for hemolytic samples and by 27 laboratories (71.05%) for lipemic samples; the colorimetric card method was used by 10 laboratories (26.32%) for assessing both hemolytic and lipemic samples; the instrumental method was used by 1 laboratory (2.63%) for assessing lipemic samples.3) The handling procedures for hemolytic and lipemic samples varied significantly and followed a gradient distribution pattern among 38 laboratories (including accepting samples for testing, accepting samples for concession testing, re-collecting samples, and rejecting samples and halting testing). With increasing severity of hemolysis and lipemia, more laboratories halted testing, and relatively fewer laboratories accepted samples for normal testing. 5 laboratories (13.16%) applied different handling procedures on serological and nucleic acid samples. Conclusion: This survey provides a reference and basis for analyzing gaps in the management of hemolytic and lipemic samples during the preanalyical phase in blood station laboratories in North China. It enables laboratories to identify the problems and deficiencies in the management of hemolytic and lipemic samples, to ensure preanalytical samples quality meets the established requirements, and to lay a foundation for promoting the homogenization and standardization of the regional sample quality management mode.

Background::Coronavirus disease 2019 (COVID-19) has potential risks for both clinically worsening pulmonary hypertension (PH) and increasing mortality. However, the data regarding the protective role of vaccination in this population are still lacking. This study aimed to assess the safety of approved vaccination for patients with PH.Methods::In this national prospective cohort study, patients diagnosed with PH (World Health Organization [WHO] groups 1 and 4) were enrolled from October 2021 to April 2022. The primary outcome was the composite of PH-related major adverse events. We used an inverse probability weighting (IPW) approach to control for possible confounding factors in the baseline characteristics of patients.Results::In total, 706 patients with PH participated in this study (mean age, 40.3 years; mean duration after diagnosis of PH, 8.2 years). All patients received standardized treatment for PH in accordance with guidelines for the diagnosis and treatment of PH in China. Among them, 278 patients did not receive vaccination, whereas 428 patients completed the vaccination series. None of the participants were infected with COVID-19 during our study period. Overall, 398 patients received inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine, whereas 30 received recombinant protein subunit vaccine. After adjusting for baseline covariates using the IPW approach, the odds of any adverse events due to PH in the vaccinated group did not statistically significantly increase (27/428 [6.3%] vs. 24/278 [8.6%], odds ratio = 0.72, P = 0.302). Approximately half of the vaccinated patients reported at least one post-vaccination side effects, most of which were mild, including pain at the injection site (159/428, 37.1%), fever (11/428, 2.6%), and fatigue (26/428, 6.1%). Conclusions::COVID-19 vaccination did not significantly augment the PH-related major adverse events for patients with WHO groups 1 and 4 PH, although there were some tolerable side effects. A large-scale randomized controlled trial is warranted to confirm this finding. The final approval of the COVID-19 vaccination for patients with PH as a public health strategy is promising.
