		                        			Ischemic stroke (IS) is a serious cerebrovascular disease common in clinical practice. Targeting the pathogenesis of IS, intravenous thrombolysis for restoring blood flow is still the most effective therapy. However, intravenous thrombolysis has shortcomings such as increased bleeding risk, narrow therapeutic window, and contraindications, which limited its clinical application. Protection of the ischemic brain tissue before full recovery of blood flow is associated with the prognosis of IS. Studies have identified multiple pathways in the alleviation of the brain injury caused by IS, such as the mammalian target of rapamycin (mTOR) signaling pathway. Traditional Chinese medicine (TCM) has abundant therapies and unique advantages in the treatment of IS, especially in alleviating symptoms and improving the quality of life of patients. After the onset of IS, TCM can be integrated with Western medicine to play a role in the whole process of treatment, rehabilitation, and recurrence prevention as soon as possible, thus maximizing patient benefits. TCM has clinical significance for the recovery of neurological and motor functions after IS. Studies have shown that TCM can reduce the cerebral injury caused by IS by regulating and activating the mTOR signaling pathway, thereby regulating autophagy, inhibiting apoptosis of nerve cells, and reducing oxidative stress and inflammation. TCM exerts a positive effect for achieving cerebral protection and improving the prognosis of IS and provides new ideas for the prevention and treatment of IS. This article introduces the role of the mTOR signaling pathway in the pathogenesis of IS and reviews the research progress in the TCM regulation of this pathway in the treatment of IS, aiming to provide new therapeutic ideas and systematic scientific reference for the treatment of IS with TCM.

		                        			Objective:To investigate the effect of iron deficiency on the prognosis of elderly patients with ejection fraction preserved heart failure (HFpEF).Methods:The clinical data of old patients (>75 years) with HFpEF from November 2021 to May 2023 in General Hospital of Eastern Theater of the Chinese People′s Liberation Army were retrospectively analyzed. The patients were divided into iron deficiency group (65 cases) and non-iron deficiency group (90 cases) according to serum ferritin (SF) and transferrin saturation (TSAT) at admission. The first hematological indexes and echocardiogram examination results after admission were compared between two groups. The patients were followed up until November 2023, the poor prognosis was recorded. The correlation between iron deficiency, iron metabolism indexes and poor prognosis in elderly patients with HFpEF was analyzed by Spearman correlation analysis. The Kaplan-Meier survival curve was drawn to analyze the effect of iron deficiency on the cumulative survival in elderly patients with HFpEF.Results:There were no statistical difference in triglyceride, total cholesterol, low density lipoprotein cholesterol, C-reactive protein, hemoglobin and echocardiogram indexes between the two groups ( P>0.05). The N-terminal pro-brain natriuretic peptide (NT-proBNP), creatinine, procalcitonin (PCT) and interleukin-6 (IL-6) in iron deficiency group were significantly higher than those in non-iron deficiency group: 427.23 (281.00, 736.90) pmol/L vs. 313.50 (182.47, 363.25) pmol/L, (167.93 ± 51.22) μmol/L vs. (121.71 ± 11.99) μmol/L, 0.12 (0.05, 0.22) μg/L vs. 0.07 (0.04, 0.16) μg/L and 25.60 (8.38, 47.01) ng/L vs. 10.15 (4.75, 19.89) ng/L, the SF, serum iron (SI) and TSAT were significantly lower than those in non-iron deficiency group: 75.40 (42.30, 198.00) μg/L vs. 207.00 (281.00, 736.90) μg/L, (6.49 ± 2.66) μmol/L vs. (12.75 ± 4.24) μmol/L and (16.65 ± 6.26)% vs. (33.78 ± 11.16)%, and there were statistical differences ( P<0.01 or <0.05). The patients were followed up for (12.06 ± 7.58) months, the all-cause mortality, cardiovascular mortality, readmission rate and heart failure readmission rate in iron deficiency group were significantly higher than those in non-iron deficiency group: 40.0% (26/65) vs. 20.0% (18/90), 18.5% (12/65) vs. 4.4% (4/90), 90.8% (59/65) vs. 70.0% (63/90) and 66.2% (43/65) vs. 17.8% (16/90), and there were statistical differences ( P<0.01). Spearman correlation analysis result showed that the iron deficiency was positive correlation with all-cause death, cardiovascular death, readmission and heart failure readmission in elderly patients with HFpEF ( P<0.01); the SI and TSAT were negative correlation with all-cause death, cardiovascular death, readmission and heart failure readmission ( P<0.01 or <0.05); and the SF was not correlation with the indexes ( P>0.05). Kaplan-Meier survival analysis result showed that the risk of all-cause death was significantly increased in elderly HFpEF patients with iron deficiency, and the cumulative survival rate was significantly reduced (log-rank χ2 = 6.48, P<0.05). Conclusions:The elderly HFpEF patients with iron deficiency have poor prognosis with high mortality and readmission rate.

		                        			ObjectiveTo investigate the current status of personnel training, barriers and bottlenecks at Shanghai Municipal and district Centers for Disease Control and Prevention (hereinafter referred to as" CDC"), so as to provide a reference basis for the formulation of training policies that are consistent with the CDC’s staff development path, characteristics of the era, and features of Shanghai mega⁃city. MethodsQuestionnaire survey and qualitative interview were used to collect the data, covering the basic information of the research subjects, as well as training status, needs, barriers and problems. A total of 800 questionnaires were distributed, and 768 valid questionnaires were returned, and frequency counts and composition ratios were used for statistical description. ResultsAmong the research subjects, 568 of which were females, accounting for 73.96%, with an average age of 36.51 years. Almost 93.10% of the research subjects had participated in training in the last year, while 6.90% of whom hadn’t attended any kind of training ever, with the main reasons as follows: failure to receive notification of training, unavailability of work, lack of funding, limited number of places and unsuitable content. Furthermore, 12.63% of the research subjects thought the trainings provided could not satisfy the requirements for continuing medical education credits, and the top three common forms of training were lectures/conferences, training courses with credits, and online courses. 97.27% of the research subjects had a need for training, and 56.12% of which expected to train for 2‒3 days, and the ideal number of training sessions per year was 2‒3 and 4‒5 times. All the staff, whether they were from the municipal CDC or district CDC, preferred practical training and case lectures to theoretical lectures. However, staff from municipal CDC had a higher demand for official document writing and research project design, and staff from district CDC had a higher demand for data software analysis and thesis writing. Bottlenecks mainly included some training needs incapable of being satisfied currently, single form of training that didn’t take advantage of the support of digital technology and lacked flexibility and convenience, and a lack of channels and mechanisms for the dissemination and transmission of training information. ConclusionStrategies to improve the training of CDC personnel at both the district and municipal levels include the creation of a hierarchical and progressive training model and system for different populations, an extension of training forms, containing the establishment of a unified training platform and the creation of an online knowledge base; and the construction of a unified and open platform with a smooth release and transfer mechanism for the dissemination of training information.

		                        			Alzheimer′s disease (AD) is a neurodegenerative disease with insidious onset and progressive development, with high disability and mortality rate. At present, there is no effective therapeutic drug. With the acceleration of population aging in China, AD poses a serious threat to public health system and social economy. Recent studies have found that the glycolysis disorder of astrocytes is involved in the progress of AD, which is closely related to the cognitive impairment of AD. The relationship between glycolytic metabolism of astrocytes and cognitive function was reviewed, and the relationship between glycolytic damage of astrocytes and cognitive impairment of AD and its mechanism were elaborated in detail, in order to provide reference for further understanding the new mechanism of cognitive impairment of AD and formulating clinical prevention and treatment strategies for AD.

		                        			 Background/Aims:
		                        			Metabolic dysfunction-associated steatotic liver disease (MASLD) has become an increasingly important health challenge, with a substantial rise linked to changing lifestyles and global obesity. Ursolic acid, a natural pentacyclic triterpenoid, has been explored for its potential therapeutic effects. Given its multifunctional bioactive properties, this research further revealed the pharmacological mechanisms of ursolic acid on MASLD. 
		                        		
		                        			Methods:
		                        			Drug target chips and bioinformatics analysis were combined in this study to explore the potential therapeutic effects of ursolic acid on MASLD. Molecular docking simulations, surface plasmon resonance analyses, pull-down experiments, and co-immunoprecipitation assays were used to verify the direct interactions. Gene knockdown mice were generated, and high-fat diets were used to validate drug efficacy. Furthermore, initial CD4+ T cells were isolated and stimulated to demonstrate our findings. 
		                        		
		                        			Results:
		                        			In this study, the multifunctional extracellular matrix phosphorylated glycoprotein secreted phosphoprotein 1 (SPP1) was investigated, highlighting its capability to induce Th17 cell differentiation, amplifying inflammatory cascades, and subsequently promoting the evolution of MASLD. In addition, this study revealed that in addition to the canonical TGF-β/IL-6 cytokine pathway, SPP1 can directly interact with ITGB1 and CD44, orchestrating Th17 cell differentiation via their joint downstream ERK signaling pathway. Remarkably, ursolic acid intervention notably suppressed the protein activity of SPP1, suggesting a promising avenue for ameliorating the immunoinflammatory trajectory in MASLD progression. 
		                        		
		                        			Conclusions
		                        			Ursolic acid could improve immune inflammation in MASLD by modulating SPP1-mediated Th17 cell differentiation via the ERK signaling pathway, which is orchestrated jointly by ITGB1 and CD44, emerging as a linchpin in this molecular cascade.
