BACKGROUND:Spinal cord injury is a neurological disorder caused by traumatic or non-traumatic events,often leading to severe functional impairment below the injured segment.In recent years,neural stem cell transplantation has been considered to have significant therapeutic potential in regulating the inflammatory response after spinal cord injury,inhibiting excessive proliferation of glial scars,and promoting nerve regeneration. OBJECTIVE:To review and discuss the potential mechanism of action of acupuncture and neural stem cell transplantation therapy in inhibiting spinal cord injury-induced secondary injury,and to delve into the scientific basis for its treatment of spinal cord injury. METHODS:PubMed,Elsevier,WanFang,and CNKI databases were searched using"spinal cord injury,acupuncture,neural stem cells,SDF-1α/CXCR4 axis"as Chinese and English search terms.Totally 96 articles were finally included.The research findings of acupuncture combined with neural stem cells in the treatment of spinal cord injury were summarized and analyzed,and the mechanism of this combination therapy in the treatment of secondary injury after spinal cord injury was summarized. RESULTS AND CONCLUSION:(1)The stromal-derived factor 1α(SDF-1α)/chemokine receptor 4(CXCR4)axis plays a crucial role in neural stem cell transplantation for spinal cord injury.This signaling mechanism not only affects neural stem cell migration,proliferation,and differentiation,but is also a key factor in determining the efficiency of stem cell homing to the injury site.Therefore,the regulation of targeting this axis is of great significance in enhancing the therapeutic effect of spinal cord injury.(2)Acupuncture,as a traditional Chinese medicine therapy,shows unique advantages in the regulation of secondary injury in spinal cord injury.It can effectively reduce secondary injury after spinal cord injury by regulating inflammatory response,inhibiting apoptosis,improving microcirculation,reducing glial scar formation,and counteracting oxidative stress.(3)Acupuncture was also able to influence the expression and function of the SDF-1α/CXCR4 axis,thereby enhancing the homing and survival ability of neural stem cells and promoting nerve regeneration and functional recovery.(4)The therapy combining acupuncture and stem cell transplantation is an innovative treatment strategy for spinal cord injury and suitable for repairing neural circuits.It combines the wisdom of traditional Chinese medicine with the advantages of modern biotechnology,providing a new treatment option for spinal cord injury patients.However,this combination therapy is still in the research and exploration stage,and its long-term efficacy and safety need to be further verified.(5)Taken together,acupuncture and neural stem cell transplantation for the treatment of spinal cord injury has great potential for clinical application,but in-depth research and optimization of treatment options are still needed.In the future,we look forward to further revealing the efficacy mechanism and optimal indications of this therapy through more clinical trials and mechanism studies,so as to bring better hope of recovery and more efficient therapeutic effects to spinal cord injury patients.

Seven novel acylphloroglucinol-sesquiterpenoid adducts, designated as dryatraols J-P (1-7), were isolated from the rhizomes of Dryopteris atrata (Wall. ex Kunze) Ching. The structures, including absolute configurations, were elucidated using comprehensive spectroscopic data, calculated 13C Nuclear Magnetic Resonance-Diastereotopic Probability Assignment Plus (13C NMR-DP4+) probability analysis, and ECD calculations. These structures represent a rare subclass of carbon skeleton of acylphloroglucinol-sesquiterpenoid adducts with a furan ring connecting the acylphloroglucinol and sesquiterpenoid moieties. Notably, compounds 1-6 are the first reported examples of acylphloroglucinol-sesquiterpenoid adducts with dimeric acylphloroglucinol incorporated into the aristolane- or rulepidanol-type sesquiterpene, while compound 7 features a hydroxylated monomeric acylphloroglucinol motif. A preliminary evaluation of their antiviral activities revealed that compounds 1-6 exhibited more potent activities against respiratory syncytial virus (RSV) with IC50 values ranging from 0.75 to 3.12 μmol·L-1 compared to the positive control (ribavirin).

ObjectiveTo analyze the impact of diabetes-related deaths on the probability of premature mortality and life expectancy in Minhang District of Shanghai from 2004 to 2023, and to provide reference data for the optimization of targeted prevention and control strategies. MethodsAll death cases involving diabetes among the registered residents of Minhang District from 2004 to 2023 were collected. The probability of premature mortality and life expectancy was computed using the abridged life table method. The average annual percent change (AAPC) was calculated with Joinpoint 4.9.0.0. The Arriaga decomposition method was employed for statistical analyses of the influence of cause-specific and age-specific mortality related to diabetes on life expectancy. ResultsThe total number of diabetes-related mortality, crude mortality, and standardized mortality for both males and females in Minhang District from 2004 to 2023 exhibited an increasing trend (P<0.001). The primary causes of death among diabetes-related cases were cardiovascular disease (37.68%), diabetes mellitus (31.95%), and malignant tumor (17.80%). From 2004 to 2023, probability of premature mortality to diabetes-related diseases demonstrated a rising trend (P<0.001), contrasting with the declining trend observed in the overall population (P=0.001). Males showed a significant upward trajectory (P<0.001), while females displayed a stable pattern. Among the diseases exerting considerable influence, cardiovascular disease and malignant tumor revealed a marked increase over time (P<0.001), whereas diabetes mellitus maintained a stable trend; both factors negatively impacted the reduction in probability of premature mortality. From 2004 to 2023, diabetes-related mortality reduced life expectancy among residents by an average of 1.22 years (-49.89%), indicating a negative impact; the reduction was 1.41 years in males and 0.90 years in females. The age groups exhibiting greater negative contributions differed by genders, namely males aged 50‒54 years and females aged 70‒74 years. Cardiovascular disease, diabetes mellitus, and malignant tumor contributed significantly to this decline (-0.46 years, -0.42 years, -0.20 years, respectively), with male experiencing higher negative contributions than females. ConclusionIn Minhang District, the rising mortality associated with diabetes-related diseases negatively impact both the reduction of the probability of premature mortality and the increase in life expectancy. This trend is primarily attributed to the rapid escalation of mortality and younger age demographic of male residents, which warrants significant attention. It is recommended that, based on the enhancement of case management, efforts should be directed towards the targeted prevention and control of risk factors and high-risk populations.

ObjectiveTo compare the development status of health facilities in different regions (non-agricultural and agricultural districts)and different types across four dimensions: organizational management, health environment, health activities, and health outcomes, to explore factors that may affect the current development status and summarize effective experiences, and to provide a foundation for the subsequent comprehensive, standardized, and effective promotion of health facility development and tiered and classified management. MethodsInvestigators conducted a health status survey based on the four dimensions for 50 health facilities in 16 districts of Shanghai, representing three types (including government agencies, enterprises, and communities). Evaluation forms were filled out through on-site observation and document reviews, which were developed in accordance with the Shanghai Health Settings Evaluation Standards (for trial implementation in 2019). ResultsThe average total score of health facilities in Shanghai was (88.42±11.93) points, with an overall excellence rate of 86.0%. The excellence rate of each dimension, from highest to lowest, were healthy environment (84.0%), organizational management (82.0%), health activities (78.0%), and health outcomes (44.0%). Health facilities in agricultural districts scored higher in both total score and average score on the organizational management dimension compared to non-agricultural districts. The excellence rate for the organizational management dimension was also higher in agricultural districts than in non-agricultural districts. There was no statistical significance in the total score, the score of each dimension, the overall excellence rate, and the excellence rate of each dimension among different types of health facilities (P>0.05). ConclusionThe development of health facilities among government agencies, enterprises, and communities in Shanghai has begun to yield positive results. Health facilities in non-agricultural districts should actively draw on the experience of those in agricultural districts, particularly in organizational management, adjust development ideas and planning based on their own realities, so as to continuously improve the levels of development.

The development of health-promoting hospitals is an important part of the Healthy China Initiative, facilitating the transformation of medical institutions from a primary focus on medical and surgical treatments to a patient-centered approach prioritizing public health. To promote the scientific, standardized, and sustainable development of health-promoting hospitals, the Shanghai Municipal Center for Health Promotion, together with Shanghai General Hospital and other institutions, has jointly developed the Standards for the Development of Health⁃promoting Hospitals (Standards) in accordance with the principles of scientific rigor, feasibility, and advancing with the times. The Standards outlines the requirements for the development of health-promoting hospitals across four aspects: organizational and institutional guarantees, creation of a healthy environment, implementation of health education and promotion, and evaluation. It is applicable to all levels and types of public medical institutions in Shanghai, and can also be referred to and implemented by other medical institutions. The introduction of the Standards is of great significance for promoting the formation of a long-term mechanism in health-promoting hospitals. This paper introduces the basis, principles, main content, precautions, and implementation suggestions of the Standards. Taking into account relevant policies and standards, it interprets the technical aspects in the process of developing health-promoting hospitals, which is helpful for medical institutions and their management to better understand and apply the standards in their work.

BACKGROUND:A pathophysiological feature of septic organ failure is endothelial dysfunction in sepsis(EDS).The physiological and pathological mechanism of sepsis is considered to be vascular leakage caused by endothelial dysfunction.These pathological changes lead to systemic organ injury.However,an analysis using bibliometric methods has not yet been conducted in the field of EDS.This study was conducted to provide an overview of knowledge structure and research trends in the field of EDS. METHODS:Based on previous research,a literature search was performed in the Web of Science Core Collection(WoSCC)for publications associated with EDS published between the year 2003 and 2023.Various types of data from the publications,such as citation frequency,authorship,keywords and highly cited articles,were extracted.The"Create Citation Report"feature in the WoSCC was employed to calculate the Hirsch index(h-index)and average citations per item(ACI)of authors,institutions,and countries.To conduct bibliometric and visualization analyses,three bibliometric tools were used,including R-bibliometrix,CiteSpace(co-citation analysis of references),and VOSviewer(co-authorship analysis of institutions,co-authorship analysis of authors,co-occurrence analysis of keywords). RESULTS:After excluding invalid records,the study finaly included 4,536 publications with 135,386 citations.Most of these publications originated in the USA,China,Germany,Canada,and Japan.Harvard University emerged as the most prolific institution,while professor Jong-Sup Bae and his research team at Kyungpook National University emerged as authors with the greatest influence.The"protein C","tissue factor","thrombin","glycocalyx","acute kidney injury","syndecan-1"and"biomarker"were identified as prominent areas of research.Future research may focus on molecular mechanisms(such as as vascular endothelial[VE]-cadherin regulation)and therapeutic interventions to enhance endothelial repair and function. CONCLUSION:Our findings show a growing interest in EDS research.Key areas for future research include signaling pathways,molecular mechanisms,endothelial repair,and interactions between endothelial cells and other cell types in sepsis.

BACKGROUND:Cell death and neuroinflammation are two important targets in the treatment of spinal cord injury.Pyroptosis is a programmed cell death closely related to neuroinflammation and targeted inhibition of pyroptosis after spinal cord injury is a promising therapeutic strategy. OBJECTIVE:To summarize the molecular mechanism,positive and negative regulatory factors and therapeutic strategies of pyroptosis in spinal cord injury. METHODS:The search terms were"spinal cord injury,pyroptosis,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),Caspase,Gasdermin D(GSDMD),IL-1β,IL-18"and 93 English literatures included in PubMed and Web of Science were finally selected for review. RESULTS AND CONCLUSION:As a newly discovered programmed cell death,pyroptosis has been shown to play an important role in the secondary injury stage after spinal cord injury.Among the regulatory factors of pyroptosis after spinal cord injury,CD73,NRF2,GDF-11,dopamine,FANCC and miR-423-5P could inhibit pyroptosis,while TLR4 and Aopps could promote pyroptosis.In terms of treatment,the active ingredients of traditional Chinese medicine(paeonol,tripterine,betulinic acid,piperine,kaempferol,and camptothecin),exosomes of various cell origins,and some drugs(metformin,topotecan,lithium,zinc,and carbon monoxide-releasing molecule 3)can effectively inhibit pyroptosis and reduce secondary spinal cord injury,but the toxicity and specific dose of these drugs need to be further studied.The specific molecular mechanism by which pyroptosis aggravates spinal cord injury is still poorly understood.The role of non-classical pathways and other inflammasomes is worth further exploration.At present,the research on pyroptosis after spinal cord injury only stays at the animal experiment stage.There are no related clinical studies and no approved targeted therapeutic drugs.(6)The application of pyroptosis after spinal cord injury has great potential,and its specific regulatory mechanism should be further studied in the future to provide a new target for the treatment of spinal cord injury.

Objective:To summarize the clinical, pathological and molecular characteristics of various types of pediatric glioma, and to explore the differences in the morphology and clinical significance among various types of pediatric glioma.Methods:Based on the fifth edition of the World Health Organization classification of central nervous system tumors, this study classified or reclassified 111 pediatric gliomas that were diagnosed at Guangzhou Medical University Affiliated Women and Children′s Medical Center from January 2020 to June 2023. The clinical manifestations, imaging findings, histopathology, and molecular characteristics of these tumors were analyzed. Relevant literature was also reviewed.Results:The 111 patients with pediatric glioma included 56 males and 55 females, with the age ranging from 10 days to 13 years (average age, 5.5 years). Clinically, manifestations presented from 5 days to 8 years before the diagnosis, including epilepsy in 16 cases, increased intracranial pressure in 48 cases and neurological impairment in 66 cases. MRI examinations revealed tumor locations as supratentorial in 43 cases, infratentorial in 65 cases, and spinal cord in 3 cases. There were 73 cases presented with a solid mass and 38 cases with cystic-solid lesions. The largest tumor diameter ranged from 1.4 to 10.6 cm. Among the 111 pediatric gliomas, there were 6 cases of pediatric diffuse low-grade glioma (pDLGG), 63 cases of circumscribed astrocytoma glioma (CAG), and 42 cases of pediatric diffuse high-grade glioma (pDHGG). Patients with pDLGG and CAG were younger than those with pDHGG. The incidence of pDLGG and CAG was significantly lower in the midline of the infratentorial region compared to that of pDHGG. They were more likely to be completely resected surgically. The pDLGG and CAG group included 4 cases of pleomorphic xanthoastrocytoma, showing histological features of high-grade gliomas. Among the high-grade gliomas, 13 cases were diffuse midline gliomas and also showed histological features of low-grade glioma. Immunohistochemical studies of H3K27M, H3K27ME3, p53, ATRX, BRAF V600E, and Ki-67 showed significant differences between the pDLGG and CAG group versus the pDHGG group ( P<0.01). Molecular testing revealed that common molecular variations in the pDLGG and CAG group were KIAA1549-BRAF fusion and BRAF V600E mutation, while the pDHGG group frequently exhibited mutations in HIST1H3B and H3F3A genes, 1q amplification, and TP53 gene mutations. With integrated molecular testing, 2 pathological diagnoses were revised, and the pathological subtypes of 35.3% (12/34) of the pediatric gliomas that could not be reliably classified by histology were successfully classified. Conclusions:There are significant differences in clinical manifestations, pathological characteristics, molecular variations, and prognosis between the pDLGG, CAG and pDHGG groups. The integrated diagnosis combining histology and molecular features is of great importance for the accurate diagnosis and treatment of pediatric gliomas.
