Nanoparticle delivery systems have good application prospects in the field of precision therapy, but the preparation process of nanomaterial has problems such as short in vivo circulation time, easy recognition, and clearance by the immune system in the body. In recent years, biomimetic nanoparticle delivery systems mediated by natural cell membranes have become a research hotspot to address these issues. The natural membrane biomimetic nanoparticle delivery system cleverly integrates the advantages of natural biofilm "autologous" and "artificial" functional carriers by using endogenous cell membranes to modify the surface of nanocarriers, endowing them with characteristics such as tumor targeting, low immunogenicity, and long blood circulation. Currently, biomimetic nanoparticle delivery systems have been used in the treatment of malignant tumors, cardiovascular diseases, bacterial infections, and other diseases. This paper analyzes the development status and current research hotspots of natural cell membrane camouflaged biomimetic nanoparticle delivery systems mainly reviews the latest research progress of red blood cell membrane camouflaged biomimetic nanoparticle delivery systems in the field of disease treatment in recent years. It focuses on exploring the advantages, future development prospects, and limitations of biomimetic nanoparticle delivery systems based on red blood cell membrane camouflage in improving drug delivery, to provide a reference for the in-depth research and development of this system.

Objective: To investigate the trends in disease burden due to childhood asthma in China from 1990 to 2021 and to project the disease burden from 2022 to 2035, so as to provide insights into formulation of the control interventions for childhood asthma in China. Methods: The prevalent case, agestandard prevalence, disability-adjusted life years (DALYs) and agestandard DALYs rate of children with asthma at ages of 0 to 14 years and their 95% uncertainty interval (UI) in China from 1990 to 2021 were extracted from the Global Burden of Disease (GBD) database. The temporal trends in the disease burden of childhood asthma were evaluated with estimated annual percentage change (EAPC) and its 95% confidence interval (CI), and the disease burden due to asthma was projected among children at ages of 0 to 14 years in China using a Bayesian age-period-cohort (BAPC) model from 2022 to 2035. Results: There were 9.368 3 million (95%UI=6.410 7 million to 14.026 1 million) prevalent cases of asthma among children at ages of 0 to 14 years in China in 2021, contributing to 0.387 9 million (95%UI=0.216 1 million to 0.668 8 million) DALYs loss. The prevalent cases and DALYs of asthma decreased by 37.28% and 52.55% among children at ages of 0 to 14 years in China in 2021 compared with 1990, and the agestandardized prevalence [EAPC=-0.70%, 95%CI=-1.26% to -0.13%)] and DALY rates [EAPC=-1.71%, 95%CI=-2.32% to -1.10%)] also appeared a tendency towards a decline. From 1990 to 2021, the prevalent cases, prevalence, DALYs and DALYs rate of asthma were all higher among male children than among female children, and the disease burden of asthma was higher among children at ages of 5 to 9 years than at other age groups. BAPC model predicted a decline in both prevalent cases and DALYs of asthma among children at ages of 0 to 14 years in China from 2022 to 2035, with 6.759 6 million prevalent cases and DALYs of 0.228 4 million personyears in 2035, while the prevalence and DALYs rates were projected to rise to 5 143.35/105 and 173.75/105 in 2035. Conclusions Despite a reduction in the disease burden of asthma among children at ages of 0 to 14 years in China from 1990 to 2021, the prevalence remained high. The disease burden due to asthma is projected to appear a decline among children at ages of 0 to 14 years in China from 2022 to 2035; however, the prevalence and DALYs rates still rise. Intensified control measures and targeted interventions are required to reduce the disease burden of childhood asthma.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

Objective:To evaluate the short-term safety and efficacy of total laparoscopic, laparoscopy-assisted, and open total gastrectomy in patients with gastric cancer who have undergone neoadjuvant therapy.Methods:In this retrospective cohort study, relevant clinical data on 243 patients who had undergone radical total gastrectomy after receiving neoadjuvant therapy were collected. These patients had been admitted to the First Affiliated Hospital of Air Force Medical University, Yuncheng Central Hospital of Shanxi Province, and Heji Hospital Affiliated to Changzhi Medical College between January 2020 and April 2024. Among them, 202 were male (83.1%) and 41 were female (16.9%), and their average age was 61.3±8.1 years. The patients were allocated to three groups according to surgical procedure: total laparoscopic (68 cases), laparoscopic- assisted (79 cases), and open surgery (96 cases). We compared relevant baseline characteristics, neoadjuvant treatment, intraoperative and postoperative conditions, postoperative histopathological findings, and related complications between these three groups.Results:There were no statistically significant differences in baseline characteristics or neoadjuvant treatment between the three groups (all P>0.05). The operative time was longer in the total laparoscopic group than in the laparoscopic-assisted and open surgery groups (267.7±37.9 minutes vs. 243.9±38.3 minutes vs. 219.7±41.2 minutes, respectively; F=7,112.278; P<0.001). However, more lymph nodes were harvested in the total laparoscopic group than in the laparoscopic-assisted and open surgery groups (27.8±4.8 vs. 27.4±6.3 vs. 27.2±5.1, respectively; F=6.042; P=0.002). Additionally, the total laparoscopic group had shorter times to first postoperative flatus (2.3±0.7 days vs. 2.4±0.7 days vs. 2.6±0.6 days, respectively; F=5.094; P=0.006] and first postoperative bowel movement (2.9±0.5 days vs. 3.0±0.6 days vs. 3.0±0.6 days, respectively; F=3.929; P=0.020). There were no statistically significant differences in intraoperative blood loss, intraoperative transfusion rates, postoperative intensive care unit admission rates, maximum tumor diameter, number of positive lymph nodes dissected, TNM stage, time to first postoperative oral intake, time to drain removal, or length of hospital stay between the three groups (all P>0.05). Among the 243 patients, 22 developed postoperative complications, making the overall complication rate 9.1%. Six patients (8.8%) in the total laparoscopic group developed complications, comprising two (2.9%) Grade IIIa Clavien-Dindo complications. One of these patients (1.5%) was readmitted within 30 days due to complications. Seven patients (8.9%) in the laparoscopic-assisted group developed complications, comprising two (2.5%) Grade IIIa Clavien-Dindo complications. One of these patients was readmitted within 30 days and another was within 90 days due to complications. Nine patients (9.4%) in the open surgery group developed complications, comprising four (4.2%) Grade IIIa Clavien-Dindo complications. Two patients (2.1%) were readmitted within 30 days and another (1.0%) within 90 days due to complications. There were no statistically significant differences among the three surgical approaches in overall postoperative complication rates, Clavien-Dindo grades, or readmission rates 30 and 90 days postoperatively (all P>0.05). Conclusions:In patients with gastric cancer who have undergone neoadjuvant therapy, there are no significant differences in the overall safety and short-term effectiveness of the three surgical procedures. Although the operative time is longer for total laparoscopic total gastrectomy, this procedure offers the advantages of faster postoperative recovery and earlier resumption of feeding.

Objective:To investigate the effect of Omaha system interventional management on therapeutic effect and incidence of major adverse cardiovascular events(MACE)during follow-up in patients with heart failure(HF).Methods:This randomized controlled study enrolled 110 HF patients treated in Second Affiliated Hospital of Chi-nese PLA Air Force Military Medical University between January 2021 and January 2023.They were divided into control group(n=55,routine nursing)and intervention group(n=55,interventional management based on Omaha system).Both groups received intervention for 1 month and were followed up for 6 months.The heart function,negative emotion,self-care capacity,quality of life,and cumulative incidence of MACE during the 6-month fol-low-up were compared between two groups.Results:Compared with patients in the control group,those in the in-tervention group had significant higher left ventricular ejection fraction(LVEF)[(60.32±4.79)％vs.(50.11±4.58)％],scores of exercise of self-care agency(ESCA)[(142.33±6.58)points vs.(89.26±7.19)points]and General Quality of Life Inventory 74(GQOLI-74)[(88.61±4.15)points vs.(70.59±7.85)points](P＜0.001 all),and significant lower left atrial diameter(LAD)[(36.18±2.98)mm vs.(40.25±3.05)mm],left ventricu-lar end-systolic diameter(LVESd)[(42.11±3.46)mm vs.(48.49±3.78)mm],scores of hospital anxiety and depression scale[HADS(A)][(10.05±2.11)points vs.(14.33±2.05)points]and HADS(D)[(9.15±1.31)points vs.(13.37±2.18)points](P＜0.001 all).The incidence rate of MACE in intervention group(9.09％vs.29.09％)was significantly lower than that of control group(P=0.004).Conclusion:Omaha system interventional management could significantly improve cardiac function and negative emotions,improve self-care capacity and quality of life,and reduce the incidence of MACE during follow-up in patients with heart failure.

Objective:To investigate the host and vector composition of pestis and the epidemic situation of pestis among animals in the border port areas of Longchuan County, Yunnan Province.Methods:In September 2022, a survey was conducted on rodents and their surface parasitic fleas in the border port areas of Longchuan County, according to three habitat types: residential areas, agricultural areas, and forest-shrubbery areas. Samples of murine animals organs and their surface parasitic fleas were collected for isolation and identification of Yersinia pestis. Blood samples of plague indicating animals, such as murine animals, dogs and cats were collected, and serum plague F1 antibody was detected by indirect hemagglutination assay. Meanwhile, a retrospective investigation was conducted on the occurrence of self dead rats, sick rats, and suspected cases in the local area from 2018 to 2022 through interviews with farmers. Results:A total of 168 murine animals belonging to 3 orders, 5 families, 10 genera, and 11 species were captured in three habitats in Longchuan County. Among them, the capture rate in residential areas was 5.00% (30/600), with Rattus tanezumi and Suncus murinus as dominant species, with a composition ratio of 50.00% (15/30). The capture rate in agricultural areas was 9.67% (122/1 262), with Rattus tanezumi and Suncus murinus as dominant species, with a composition ratio of 50.82% (62/122) and 44.26% (54/122), respectively. The capture rate in the forest-shrubbery areas was 6.25% (16/256), with Hylomys suillus and Eothenomys eleusis as dominant species, with a composition ratio of 37.50% (6/16) and 31.25% (5/16), respectively. Among the captured murine animals, 20 individuals carried 52 parasitic fleas, belonging to 2 species of 2 genera and 2 families. The total flea infection rate was 11.90% (20/168), and the total flea index was 0.31 (52/168). The dominant specie was Xenopsylla cheopis (90.38%, 47/52). The flea infection rate in residential areas was 33.33% (10/30), and the flea index was 1.23 (37/30). The flea infection rate in agricultural areas was 7.38% (9/122), and the flea index was 0.11 (14/122). The flea infection rate in the forest-shrubbery areas was 6.25% (1/16), and the flea index was 0.06 (1/16). The samples of murine animals and their parasitic fleas obtained were isolated and cultured by Yersinia pestis, and the results were negative. A total of 144 serum samples from murine animals, dogs and cats were separated, and no F1 antibody against pestis was detected. According to interviews and investigations, no abnormal situations such as a large number of self dead rats, sick rats, and suspected cases were found from 2018 to 2022. Conclusions:No plague epidemic has been found in the border port areas of Longchuan County recently. The main host of plague, Rattus tanezumi, and the main vector, Xenopsylla cheopis, remain the dominant species in this area.

Objective To systematically review and analyze the characteristics and current status of registered clinical trials on Traditional Chinese Medicine(TCM)for the prevention and treatment of overweight/obesity.Methods We conducted a comprehensive search of two primary clinical trial registration platforms,the Chinese Clinical Trial Registry and ClinicalTrials.gov,to extract registered information on TCM interventions for overweight/obesity.The search period spanned from the establishment of each registry to December 31,2024.Statistical analysis was performed on the extracted registration data.Results A total of 226 clinical studies were included,with a cumulative sample size of 25165 participants.The annual registration volume exhibited a significant upward trend.The majority of studies were interventional in design,with primary outcome measures focusing on anthropometric and metabolic indicators.Notably,only two trials fully met the international standards for clinical trial registration as outlined by the World Health Organization(WHO).Conclusion A quality assessment of the overall registration data revealed that the quality of trial registrations remains suboptimal.Issues such as inadequate standardization,transparency,and comprehensiveness were identified.Additionally,the geographical distribution of registered trials was uneven,and there is an urgent need to refine outcome measures related to TCM syndrome differentiation.
