Stroke is a cerebrovascular disease with high fatality and disability rates， which brings heavy psychological burden along with physical disorder to patients. In recent years， transcranial magnetic stimulation （TMS） has attracted great attention in the research on functional prognosis of stroke patients. TMS can reveal the degree of corticospinal tract injury from a neurophysiological point of view and provide key information for functional recovery， and it is widely used in the rehabilitation treatment of post-stroke dysfunction. This article reviews the basic principle， classification， mechanism of TMS in promoting functional recovery of stroke， as well as its application in rehabilitation treatment， so as to lay a foundation for individualized neurological rehabilitation and improve the long-term prognosis of patients to the largest extent.

ObjectiveTo observe and compare the effects of different concentrations of cyclophosphamide (CTX) in inducing premature ovarian insufficiency (POI) model in mice and investigate the mechanism of injury. MethodsThirty-two 6~8-week-old female C57BL/6J mice were randomly divided into four groups (n=8 per group) using a weight-based block randomization method. The POI model was established via a single intraperitoneal injection of 75 mg/kg cyclophosphamide (CTX), 120 mg/kg CTX, 120 mg/kg CTX + 12 mg/kg Busulfan, or an equivalent volume of normal saline (control). Ovarian coefficients, serum estradiol (E₂) and follicle-stimulating hormone (FSH) levels were measured. Western blotting was performed to assess changes in ovarian expression levels of NAD-dependent deacetylase sirtuin-5 (SIRT5) and forkhead box O3a (FOXO3a) under different modeling conditions. After determining the optimal CTX concentration for modeling, an additional forty 6~8-week-old femal C57BL/6J mice were randomly divided into five groups (n=8 per group) using a weight-based block randomization method: saline control, 120 mg/kg CTX sampling at 1, 2, 7, or 14 days after modeling. Western blotting was used to evaluate temporal changes of ovarian SIRT5 and FOXO3a protein expression. ResultsCompared with the saline control, all concentrations of CTX (75 mg/kg CTX, 120 mg/kg CTX) and 120 mg/kg CTX + 12 mg/kg Busulfan induced POI injury in mice. The 120 mg/kg CTX group exhibited smaller changes in ovarian coefficients (P<0.001) and E₂ levels (P<0.05), whereas the 120 mg/kg CTX + 12 mg/kg Busulfan group showed rough and reduced luster fur, sluggish response and was in the worst state. Compared with the saline control group, FOXO3a expression was significantly down-regulated (P<0.05), while SIRT5 remained unchanged in the 75 mg/kg CTX group (P>0.05). In contrast, both SIRT5 (P<0.05) and FOXO3a (P<0.05) were significantly down-regulated in the 120 mg/kg CTX group. Further analysis revealed that on day 2 and 7 after 120 mg/kg CTX modeling, the expressions of SIRT5 (P<0.01) and FOXO3a (P<0.001) were significantly down-regulated, with the largest decrease observed on day 7 (SIRT5, P<0.000 1; FOXO3a, P<0.000 1). ConclusionOvarian injury in the POI model induced by 120 mg/kg CTX is milder than that in the POI model induced by 75 mg/kg CTX. Moreover, the expression changes of SIRT5 and FOXO3a are most significant on day 7 after modeling induced by 120 mg/kg CTX, which may be related to the inhibition of the SIRT5-FOXO3a signaling pathway.

ObjectiveThe full name of vertebroplasty is percutaneous vertebroplasty (PVP). It is a clinical technique that injects bone cement into the diseased vertebral body to achieve strengthening of the vertebra. The research on the safety and efficacy of bone cement is the basis for clinical application. In this study, vertebroplasty is used to evaluate and compare the safety and efficacy of Tecres and radiopaque bone cement in experimental pigs, and to determine the puncture method suitable for pigs and the pre-clinical evaluation method for the safety and efficacy of bone cement. MethodsTwenty-four experimental pigs (with a body weight of 60-80 kg) were randomly divided into an experimental group (Group A) and a control group (Group B). Group A was the Tecres bone cement group, and Group B was the radiopaque bone cement group, with 12 pigs in each group. Under the monitoring of a C-arm X-ray machine, the materials were implanted into the 1st lumbar vertebra (L1) and 4th lumbar vertebra (L4) of the pigs via percutaneous puncture using the unilateral pedicle approach. The animals were euthanized at 4 weeks and 26 weeks after the operation, respectively. The L4 vertebrae were taken for compressive strength testing, and the L1 vertebrae were taken for hard tissue pathological examination to observe the inflammatory response, bone necrosis, and degree of osseointegration at the implantation site. ResultsThe test results of compressive strength between groups A and B showed no significant difference at 4 weeks and 26 weeks after bone cement implantation (P > 0.05). Observation under an optical microscope (×100) revealed that at 4 weeks postoperatively, both groups A and B showed that the bone cement was surrounded by proliferative fibrous tissue, with lymphocyte infiltration around it. The bone cement was combined with bone tissue, the trabecular arrangement was disordered, and osteoblasts and a small amount of osteoid were formed. At 26 weeks postoperatively, bone cement was visible in both groups A and B. The new bone tissue was mineralized, the trabeculae were fused, the trabecular structure was regular and dense with good continuity, and no obvious inflammatory reaction was observed. ConclusionIn experimental pig vertebrae, there were no significant differences observed in the compressive strength, inflammation response, bone destruction, and integration with the bone between Tecres and non-radiopaque bone cement. Both exhibited good biocompatibility and osteogenic properties. It indicates that using vertebroplasty to evaluate the safety and efficacy of bone cement in pigs is scientifically sound.

Objective:To compare the differences in postoperative healing rates, hearing improvement, and complication rates between endoscopic butterfly inlay cartilage tympanoplasty and underlay cartilage tympanoplasty in Small-to-Medium-Sized Tympanic Membrane Perforations, and to provide clinical basis for indication of the butterfly inlay cartilage tympanoplasty. Methods:This study enrolled patients with chronic suppurative otitis media or traumatic tympanic membrane perforations who were treated at the Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Chongqing Medical University, between January 2022 and May 2023. Inclusion criteria comprised a dry ear period exceeding 3 months, absence of middle ear or mastoid pathology confirmed by temporal bone CT, and an air-bone gap of less than 40 dB. All surgeries were performed by the same surgeon using tympanoplasty techniques. Based on the surgical approach and perforation size, patients were categorized into four groups: Group A（butterfly cartilage tympanoplasty, perforation ≤3 mm）: 23 cases. Group B（butterfly cartilage tympanoplasty, perforation 3-5 mm）: 17 cases. Group C（full-thickness cartilage underlay tympanoplasty, perforation ≤3 mm）: 12 cases. Group D（full-thickness cartilage underlay tympanoplasty, perforation 3-5 mm）: 22 cases. Data collected included perforation duration, preoperative Eustachian Tube Score（ETS）, pure-tone audiometry, otoscopic findings, and postoperative follow-up data on pure-tone thresholds, otoscopic outcomes, and complications such as graft infection and otorrhea. Results: The mean postoperative follow-up period was 4 months （range: 3-12 months）. A total of 74 patients were enrolled, including 40 undergoing butterfly cartilage tympanoplasty and 34 receiving full-thickness cartilage inlay tympanoplasty. In the <3 mm perforation subgroup, the patients receiving butterfly technique （23 cases） exhibited a postoperative air-bone gap （ABG） improvement of （2.33±8.21） dB, and those receiving the inlay technique （12 cases） showed an ABG improvement of （2.49±7.9） dB, with no statistically significant difference between the two groups （P>0.05）. In the 3-5 mm perforation subgroup, the patients receiving butterfly technique （17 cases） demonstrated an ABG improvement of （8.16±5.69） dB, and those receiving the inlay technique （22 cases） achieved an ABG improvement of （8.08±10.42） dB, which were not significantly different （P>0.05）. Tympanic membrane healing rates across the four subgroups were 95.65%, 94.12%, 100%, and 95.45%, respectively, with no statistically significant differences （P>0.05）. Conclusion:In patients with tympanic membrane perforations ≤3 mm and 3-5 mm, butterfly cartilage tympanoplasty achieves comparable audiological outcomes to full-thickness cartilage underlay tympanoplasty. Compared with the underlay technique, the butterfly method is less invasive, preserves the normal anatomical structure of the tympanic membrane, requires a shorter dry ear period, and yields higher patient satisfaction. Therefore, it can be safely recommended for perforations ≤5 mm that do not require tympanotomy exploration.

This study investigated the role of the nuclear factor of activated T cells c3 (NFATc3) in vascular smooth muscle cells (VSMCs) during aortic aneurysm and dissection (AAD) progression and the underlying molecular mechanisms. Cytoplasmic and nuclear NFATc3 levels were elevated in human and mouse AAD. VSMC-NFATc3 deletion reduced thoracic AAD (TAAD) and abdominal aortic aneurysm (AAA) progression in mice, contrary to VSMC-NFATc3 overexpression. VSMC-NFATc3 deletion reduced extracellular matrix (ECM) degradation and maintained the VSMC contractile phenotype. Nuclear NFATc3 targeted and transcriptionally upregulated matrix metalloproteinase 9 (MMP9) and MMP2, promoting ECM degradation and AAD development. NFATc3 promoted VSMC phenotypic switching by binding to eukaryotic elongation factor 2 (eEF2) and inhibiting its phosphorylation in the VSMC cytoplasm. Restoring eEF2 reversed the beneficial effects in VSMC-specific NFATc3-knockout mice. Cabamiquine-targets eEF2 and inhibits protein synthesis-inhibited AAD development and progression in VSMC-NFATc3-overexpressing mice. VSMC-NFATc3 promoted VSMC switch and ECM degradation while exacerbating AAD development, making it a novel potential therapeutic target for preventing and treating AAD.

The cooccurrence of NPM1, FLT3-ITD, and DNMT3A mutations (i.e., triple mutation) is related to dismal prognosis in patients with acute myeloid leukemia (AML) receiving chemotherapy alone. In this multicenter retrospective cohort study, we aimed to identify whether allogeneic hematopoietic stem cell transplantation (allo-HSCT) could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut AML across four transplant centers in China. Fifty-three patients with triple-mutated AML receiving allo-HSCT in complete remission were enrolled. The 1.5-year probabilities of relapse, leukemia-free survival, and overall survival after allo-HSCT were 11.9%, 80.3%, and 81.8%, respectively. Multivariate analysis revealed that more than one course of induction chemotherapy and allo-HSCT beyond CR1 were associated with poor survival. To our knowledge, this work is the largest study to explore the up-to-date undefined role of allo-HSCT in patients with triple-mutated AML. Our real-world data suggest that allo-HSCT could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut in AML.
