OBJECTIVE:Some studies have shown that physical exercise can effectively improve knee extensor strength and cardiorespiratory function in burn patients;some studies have also shown that physical exercise is not effective in improving respiratory function in burn patients.Improvement effects of physical exercise on physical functions(muscle function,walking function,cardiopulmonary function,and lean body mass)of burn patients were evaluated by a systematic evaluation and meta-analysis.METHODS:Based on databases including Web of Science,PubMed,Embase,Cochrane Library,CNKI,WanFang,and the Chinese Biomedical Database,literature on the improvement of physical function in burn patients through physical exercise was searched using subject headings and free terms.With muscle function,walking ability,cardiopulmonary function,and lean body mass as the primary outcome measures,a meta-analysis was conducted to compare the efficacy of physical exercise with traditional physical therapy or conventional care methods.RESULTS:A total of 38 papers were included,of which 26 papers were included in the meta-analysis,involving 1 658 patients.Meta-analysis results showed that:(1)Physical exercise significantly enhances the knee extensor strength of the dominant leg in burn patients(mean difference[MD]=8.34,95％confidence interval[CI]:6.95-9.72,P＜0.000 01),increases quadriceps strength,peak oxygen uptake,forced vital capacity and maximum ventilation volume in 1 second,and resting heart rate(standardized mean difference[SMD]=4.41,95％CI:2.52-6.30,P＜0.000 01;MD=4.91,95％CI:3.52-6.29,P＜0.000 01;MD=5.86,95％CI:0.09-11.63,P=0.05;MD=6.90,95％CI:2.93-10.87,P=0.000 7;MD=5.03,95％CI:1.45-8.61,P=0.006),and improves the 6-minute walking distance,gait parameters,and total lean body mass(MD=45.29,95％CI:24.7-65.89,P＜0.0001;SMD=7.84,95％CI:6.05-9.63,P＜0.000 01;MD=2.47,95％CI:2.01-2.93,P＜0.000 01).(2)The subgroup analysis results indicated that the improvement in knee extensor strength of the dominant leg may be better in children than in adults and better in the extra-heavy group than in the heavy group.Improvement in the 6-minute walking distance is better in children than in adults,and higher degree of burn indicates better improvement effects,with no difference from the control group for＜12 weeks.Peak oxygen uptake may be better in adults and severe burn groups than in children and moderate burn groups,resistance combined with aerobic exercise modalities may be better than aerobic exercise alone,and exercise duration＞60 minutes may be better than＜60 minutes.CONCLUSION:Physical activity is effective in improving physical function in burn patients,as evidenced by improvements in muscle strength,walking ability,cardiorespiratory fitness,and lean body mass.The quality of evidence recommended for all indicator results is moderate or below,with imprecision and inconsistency being the main factors for downgrading.Therefore,more high-quality randomized controlled trials are needed in the future to verify the reliability of the results.

ObjectiveTo analyze the epidemiological and clinical characteristics of the 21 confirmed monkeypox cases in a district of Chengdu City, and to provide scientific guidance for the prevention and control of subsequent monkeypox epidemics. MethodsData of confirmed monkeypox cases residing in this district were collected from the Disease Control and Prevention Information System of China. A retrospective descriptive epidemiological analysis was used to analyze the demographic, distributional and behavioral characteristics of the cases. ResultsThe first confirmed case of monkeypox was reported on July 5, 2023. Up to April 30, 2025, a total of 21 confirmed cases of monkeypox have been reported. All cases were male, with a mean age of (30.9±6.2) years. The highest proportion of cases(47.62%) was in the 30‒40 years age group. The majority were men who have sex with men (MSM) population (90.48%, 19/21). The results showed that 19.05% of cases were co-infected with HIV, and 19.05% had a history of syphilis infection. Within 21 days prior to symptom onset, 19 cases (90.48%) self-reported engaging in male-to-male sexual contact, among whom 10 cases (52.63%) reported having taken protective measures, while 9 cases (47.37%) did not take safety precautions. Thirteen cases (61.90%) had no travel history to areas with reported monkeypox cases during the 21 days before symptom onset. The predominant manifestation was exanthem (100%, 21/21), followed by fever (57.14%, 12/21) and lymphadenectasis (47.62%, 10/21). Among febrile cases, 50.00% (6/12) had low-grade fever (37.3‒38.0 ℃). All cases were identified through active medical consultation. The median interval from symptom onset to the first medical visit was 3 (2, 6) days, with a maximum interval of 14 days. The median interval from symptom onset to laboratory confirmation was 7 (5, 9) days. Six cases (28.57%) had two or more visits to the hospital, with bacterial infection being the primary initial diagnosis. ConclusionMonkeypox prevention and control efforts in a district of Chengdu City should prioritize MSM population and young and middle-aged adults aged 30 to <40 years. It is recommended to establish an integrated monkeypox epidemic prevention and control network by leveraging existing HIV/AIDS prevention and control network. Concurrently, accelerating the deployment of the national intelligent infectious disease monitoring and early warning front-end software will strengthen early detection capabilities and be beneficial for the overall effectiveness of epidemic prevention and control efforts.

Objective: To elucidate the pharmacological material basis of Danggui Buxue Decoction for its "blood-tonifying" effect through spectrum-effect relationship analysis.
Methods: The chemical constituents of Danggui Buxue Decoction were qualitatively analyzed using liquid chromatography-quadrupole-orbitrap mass spectrometry (LC-QE/MS). An ultra-performance liquid chromatography (UPLC) fingerprint of Danggui Buxue Decoction was established, and the common peaks of 30 batches of self-made Danggui Buxue Decoction were quantitatively analyzed. A zebrafish anemia model induced by phenylhydrazine was established, and the spectrum-effect relationship analysis method was applied to correlate the pharmacological data of 30 batches of Danggui Buxue Decoction with the fingerprint data to screen for its pharmacological material basis.
Results: A total of 90 prototype components were identified in the qualitative analysis of Danggui Buxue Decoction. The UPLC fingerprint of Danggui Buxue Decoction and the zebrafish anemia model were successfully established. The spectrum-effect relationship analysis of the pharmacological data and fingerprint data of 30 batches of Danggui Buxue Decoction revealed that the pharmacological materials of Danggui Buxue Decoction included 4-guanidinobutanoic acid (from Astragalus), isoleucine (from wine-prepared Angelica), lauric acid (from wine-prepare Angelica), ferulic acid (from both wine-prepared Angelica and Astragalus), 6-methoxy-2H-chromen-2-one (from both wine-prepared Angelica and Astragalus), sophoraisoflavone glucoside (from both wine-prepared Angelica and Astragalus), and an unknown peak 8.
Conclusion: This study screened the pharmacological material basis of Danggui Buxue Decoction through qualitative and quantitative analysis of its prototype chemical constituents combined with spectrum-effect relationship analysis, providing scientific support for the clinical application and secondary development of this classic prescription.

Objective To investigate whether Danshen injection (DSI) can protect human brain organoids from oxidative stress damage by regulating the Nrf2 signaling pathway and its mechanism. Methods A Nrf2 plasmid was constructed, lentivirus was packaged and transfected into human induced pluripotent stem cell (hiPSC) to form a stable cell line. Brain organoids with Nrf2 overexpression (LV-Nrf2 group) and knockdown (sh-Nrf2 group) were constructed using kit. The transfection efficiency was verified by real-time fluorescence quantitative polymerase chain reaction. An oxidative stress injury model was established by inducing hydrogen peroxide (H₂O₂). Intervention was performed either in combination or without DSI pre-treatment. Cell viability was detected by Cell Counting Kit-8 (CCK-8), and the expression levels of Nrf2, malondialdehyde (MDA), interleukin (IL)-1β, sex-determining region Y-box protein 2 (SOX2) and neuronal-specific nuclear protein (NeuN) were detected by Western blot and immunofluorescence staining. Total RNA from human brain organoids was extracted for transcriptome sequencing and analysis. Results LV-Nrf2 group and sh-Nrf2 group brain organoid models were successfully constructed. The CCK-8 results determined that the oxidative stress model was established with 32 mmol/L H₂O₂ intervention conditions. The fluorescence expression of Nrf2 in LV-Nrf2 group was higher than that in control group, and the fluorescence expressions of MDA and IL-1β were lower than those in control group; sh-Nrf2 group showed a damage phenotype of low Nrf2 expression, high MDA and IL-1β expression (all P < 0.05). Compared with H₂O₂ group, the Nrf2 signal in DSI + H₂O₂ group was stronger, and the levels of MDA and IL-1β were lower. Among them, the protective effect of LV-Nrf2 was the most significant. H₂O₂ treatment could down-regulate the protein levels of Nrf2, SOX2 and NeuN, and DSI intervention could effectively reverse the downward trend of these indicators. Sh-Nrf2 could weaken the recovery effect of DSI on SOX2 and NeuN, while LV-Nrf2 could synergistically enhance the regulatory effect of DSI. Conclusions DSI may antagonize oxidative stress damage in human brain organoids through the Nrf2 signaling pathway, and maintaining the stability of the neural cell lineage is its core therapeutic characteristic.

"Weibing" is a fundamental concept in traditional Chinese medicine (TCM), representing a transitional state characterized by diminished self-regulatory abilities without overt physiological or social dysfunction. This perspective delves into the biological foundations and quantifiable markers of Weibing, aiming to establish a research framework for early disease intervention. Here, we propose the "Health Quadrant Classification" system, which divides the state of human body into health, sub-health, disease-susceptible state, and disease. We suggest the disease-susceptible stage emerges as a pivotal point for TCM interventions. To understand the intrinsic dynamics of this state, we propose laboratory and clinical studies utilizing time-series experiments and stress-induced disease susceptibility models. At the molecular level, bio-omics technologies and bioinformatics approaches are highlighted for uncovering intricate changes during disease progression. Furthermore, we discuss the application of mathematical models and artificial intelligence in developing early warning systems to anticipate and avert the transition from health to disease. This approach resonates with TCM's preventive philosophy, emphasizing proactive health maintenance and disease prevention. Ultimately, our perspective underscores the significance of integrating modern scientific methodologies with TCM principles to propel Weibing research and early intervention strategies forward.

The development process and academic achievements of China in the field of Parkinson′s disease and movement disorders were summarized in this article. It began in 1978 when several Chinese professors organized the National Clinical Collaboration Group for Parkinson′s Disease to conduct clinical research and academic exchanges. In 1984, the first National Academic Conference on Extrapyramidal Diseases was held in Shanghai. In 2002, the Chinese Society of Parkinson′s Disease and Movement Disorders was officially established, promoting domestic and international academic exchanges, the popularization of clinical diagnosis and treatment standards, and research progress. The society′s active participation in international and domestic academic conferences and the important role of Chinese experts in global related academic organizations were highlighted. Over the past 40 years, the society′s hard work has significantly enhanced Chinese scientific research, diagnosis and treatment, and international influence in the field of Parkinson′s disease and movement disorders. Looking to the future, the society will continue to focus on innovative research to improve academic standards and international status, bringing greater benefits to patients.

Humanistic caring for patients in the operating room refers to providing the whole process of caring medical services for patients in the operating room. In order to standardize humanistic caring services for patients in the operating room of medical institutions, improve the comprehensive service level of the operating room, and enhance the surgical experience of patients, the Chinese Association for Life Care released the group standard " Humanistic Caring Management Standards for Patients in the Operating Room" in December 2023. This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Objective To investigate the expression levels of microRNA-152-3p(miR-152-3p)and sex determining region-box transcription factor 5(SOX5)in gastric cancer(GC)tissues and their clinical significance.Methods A total of 120 GC patients were selected as study subjects.Re-al-time quantitative polymerase chain reaction(qRT-PCR)was used to detect the expression levels of miR-152-3p and SOX5,and their relationships with the clinicopathological characteristics of GC pa-tients were analyzed.The Kaplan-Meier method was applied to draw survival curves,and the Cox re-gression model was used to screen the prognostic influencing factors of GC patients.Results The ex-pression level of miR-152-3p in GC tissues was lower than that in adjacent non-cancerous tissues,while the expression level of SOX5 was higher than that in adjacent non-cancerous tissues(P＜0.05).The expressions of miR-152-3p and SOX5 in GC tissues were all associated with lymph node metastasis,degree of differentiation,and TNM stage(P＜0.05).The expression level of miR-152-3p was negatively correlated with that of SOX5(r=-0.512,P＜0.05),and there were targeted binding sites between miR-152-3p and SOX5.The 5-year specific survival rate of the low miR-152-3p expression group was lower than that of the high miR-152-3p expression group(60.53％versus 84.09％,x2=7.256,P＜0.05).The 5-year specific survival rate of the high SOX5 expression group was 63.10％,which was lower than 83.33％of the low SOX5 expression group,with a statis-tically significant difference(x2=4.840,P＜0.05).Multivariate Cox regression analysis showed that the expression levels of miR-152-3p and SOX5,as well as the TNM stage,were all independent prog-nostic influencing factors for GC patients(P＜0.05).Conclusion Low expressions of miR-152-3p and high expression of SOX5 are observed in GC tissues,and their expression levels are closely re-lated to clinicopathological characteristics such as TNM stage and patients' prognosis.
