ObjectiveTo investigate the effect of cerebellar intermittent theta-burst stimulation (iTBS) on postural control and fall risk in stroke patients. MethodsFrom October, 2024 to August, 2025, 45 stroke patients were recruited from Huadong Hospital Affiliated to Fudan University. They were randomly divided into control group (n = 15), group A (n = 15) and group B (n = 15). All the groups received conventional medication and rehabilitation. Group A was additionally administered iTBS over the ipsilesional primary motor cortex (M1), while group B received iTBS over the contralesional cerebellum, for three weeks. Before and after intervention, postural stability indexes (eyes open/closed), limits of stability, directional control score and reaction time were measured using Biodex Balance System, and they were assessed with Berg Balance Scale (BBS), Timed Up & Go Test (TUGT) and 10-meter walk test (10MWT). ResultsAfter intervention, significant group-time interaction effects were observed for eyes open/closed postural stability indexes, limits of stability, directional control score, reaction time, BBS score, TUGT and 10MWT (F > 23.487, P < 0.001). All the groups improved in all the indexes after intervention (P < 0.01). The eyes open/closed postural stability indexes, limits of stability, directional control score and reaction time were the best in group B, followed by group A, and the worst in the control group (P < 0.05), while BBS, TUGT and 10MWT were better in groups A and B than in the control group (P < 0.05). ConclusionCerebellar iTBS can effectively improve postural control disorders and reduce fall risk in stroke patients, and may be superior to M1 iTBS.

Microglia are specialized immune cells in the brain, primarily responsible for clearing debris and responding to inflammation. One of the pathological features of Alzheimer's disease (AD) is the extensive activation of immune system in the brain, and the dynamic changes and dysfunction of microglia could become key factors for AD progression. This article reviews the research progress of regulated effect of microglial on AD pathology, and summarizes its potential value in AD treatment, in order to provide theoretical basis for exploring new therapeutic strategies and intervention targets for AD.

Objective:To explore the binding characteristics of N, N-diethyl-2-(2-(4-(2- 18F-fluoroethoxy)phenyl)-5, 7-dimethylpyrazolo[1, 5-a]pyrimidin-3-yl)acetamide ( 18F-DPA-714) and ( R)- N-sec-butyl- N-methyl-4-(3-( 18F-trifluoromethyl)phenyl)quinazoline-2-carboxamide ( 18F-TFQC) to the single nucleotide polymorphisms of the 18×10 3 translocator protein (TSPO), and to evaluate the imaging efficacy and feasibility of those 2 molecular probes in neuroinflammation rat models. Methods:To test the selectivity of 18F-DPA-714 and 18F-TFQC for TSPO polymorphisms, the wild-type (high-affinity binding, HAB) and mutant (low-affinity binding, LAB) sequences of the human TSPO gene were transfected into 293T cells respectively. A competitive inhibition assay was carried out with N-methyl- N-(1-methylpropyl)-1-(2-chlorophenyl)-3-isoquinoline carboxamide (PK11195) as an inhibitor to determine the binding affinities of 2 probes to TSPO polymorphisms. Rat neuroinflammation models ( n=6) were established using lipopolysaccharide. Three days after modeling, small animal PET/CT imaging was performed using 18F-DPA-714 and 18F-TFQC, respectively, to observe and compare the uptake of the tracers, and the ratio of SUV mean of the right striatum to SUV mean of the left striatum (SUVR) was calculated. After the imaging, the expression and distribution of microglia and TSPO were detected by tissue immunofluorescence. Repeated-measures analysis of variance was used to analyze the SUVR data of different groups. Results:The inhibition constants ( Ki) of 18F-TFQC on 293T-LAB and 293T-HAB cells were 23.51 and 14.60 nmol/L, respectively, with a Ki LAB/ Ki HAB ratio of 1.61, indicating low sensitivity to TSPO single nucleotide polymorphisms. The Ki of 18F-DPA-714 for binding to 293T-LAB and 293T-HAB cells were 45.23 and 6.47 nmol/L, respectively, with a Ki LAB/ Ki HAB ratio of 6.99. Small animal PET/CT imaging demonstrated that specifically uptake of both probes could be found in neuroinflammatory lesions. The overall SUVR of 18F-DPA-714 in the lesions within 60minutes was slightly higher than that of 18F-TFQC, but no significant difference was observed ( F values: inter-group 0.40, time effect 0.30, cross-effect 0.03; all P>0.05). Conclusions:Compared with 18F-DPA-714, 18F-TFQC is less sensitive to TSPO gene polymorphisms, thus being more suitable for clinical application and promotion. It holds promise for the early identification of neuroinflammation and the efficacy monitoring of anti-inflammatory drug treatments.

PI3K/Akt, Wnt/β-catenin, TGF-β, Nrf2 and Notch signaling pathways are mainly involved in the TCM treatment of chronic refractory wounds (CRW). Chinese materia medica monomers and compound preparations can inhibit protein kinases related to signaling pathways in wound tissue and promote wound healing; reduce the expression of inflammatory factors and inhibit the occurrence of inflammatory response; promote the proliferation and differentiation of growth factors and epidermal stem cells, accelerate the regeneration of granulation tissue, and play a role in repairing wound regeneration.

Edema， as a common pathological phenomenon， is essentially the abnormal accumulation of body fluids in the interstitial spaces of human tissues and is often a direct manifestation of various underlying diseases， such as heart failure， impaired renal filtration function， or liver metabolic disorders. In the Western medical system， strategies for treating edema primarily focus on the use of diuretics to promote the excretion of excess fluid in the body， while simultaneously addressing the underlying causes through targeted treatment. However， long-term reliance on the use of diuretics may lead to a decrease in drug sensitivity and induce side effects， including electrolyte disorders such as hypokalemia and hypercalcemia， posing a potential threat to patients' overall health. Compared with Western medicine， traditional Chinese medicine （TCM） has demonstrated well-recognized and sustained efficacy in treating edema with its unique theoretical system. Zhulingtang， as a classic and commonly used TCM formula， is widely applied as it can effectively relieve edema and related symptoms. In recent years， ongoing in-depth studies on the treatment of edema with Zhulingtang have revealed multiple mechanisms of action of Zhulingtang， including the regulation of water metabolism and the reduction of inflammatory responses， thereby providing a solid theoretical basis for clinical practice. This review summarized the research progress on the treatment of edema with Zhulingtang in recent years and analyzed the active ingredients and action pathways of Zhulingtang. Additionally， the primary mechanisms of action and efficacy were systematically analyzed， so as to provide references for the clinical application of Zhulingtang in treating various types of edema， such as cardiogenic edema， renal edema， and hepatogenic edema. This review aims to offer theoretical support and practical guidance for clinicians in deciding treatment approaches， as well as references for subsequent in-depth studies， thereby promoting further development of TCM in the treatment of edema.
