Objective To explore the effect of core muscle stability training combined with biofeedback electrical stimulation on pelvic floor muscle function in postpartum women underwent episiotomy.Methods Clinical data of 98 parturients who underwent selective episiotomy during natural childbirth were retrospectively analyzed.According to different intervention methods,the included parturients were divided into the control group and the combination group,with 49 cases in each group.The control group was treated only with biofeedback electrical stimulation therapy,while the combination group was treated with core muscle stability training combined with biofeedback electrical stimulation therapy.The general information and pelvic floor muscle strength,pelvic floor electromyography values,pelvic floor dysfunction questionnaire(PFDI-20)scores and female sexual function score scale(FSFI)scores were compared between the two groups of parturients before and after intervention.Results There were no significant differences in age,gestational age,body mass index and pelvic floor muscle strength grading between the two groups(P＞0.05).Compared with before intervention,pelvic floor muscle strength,pelvic floor electromyography values and FSFI scores increased in both groups after intervention,while PFDI-20 scores decreased(all P＜0.05).After intervention,compared with the control group,the combination group showed more significant improvement in pelvic floor muscle strength,with an increase in class Ⅰ and class Ⅱ fiber electromyography values,a decrease in PFDI-20 score,and an increase in FSFI scores(all P＜0.05).The incidence of pelvic floor dysfunction in the two groups was statistically significant(22.45%vs.6.12%,P＜0.05).Conclusion Core muscle stability training combined with biofeedback electrical stimulation can effectively promote the recovery of pelvic floor muscle function and improve sexual function in postpartum women underwent episiotomy.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Metabolic dysfunction-associated steatotic liver disease(MASLD)is the most prevalent chronic liver disease globally,with only one Food and Drug Administration(FDA)-approved drug for its treatment.Given MASLD's complex pathophysiology,ther-apies that simultaneously target multiple pathways are highly desirable.One promising approach is dual-modulation of the famesoid X receptor(FXR),which regulates lipid and bile acid metabolism.However,FXR agonists alone are insufficient due to their limited anti-inflammatory effects.This study aimed to dto identify natural products capable of both FXR activation and inflammation inhibition to provide a comprehensive therapeutic approach for MASLD.Potential FXR ligands from the Natural Product Library were predicted via virtual screening using the Protein Preparation Wizard module in Schrodinger(2018)for molecular docking.Direct binding and regulation of candidate compounds on FXR were analyzed using surface plasmon resonance(SPR)binding assay,reporter gene ana-lysis,and reverse transcription-polymerase chain reaction(RT-PCR).The anti-inflammatory properties of these compounds were eval-uated in AML12 cells treated with tumor necrosis factor-alpha(TNF-α).Dual-function compounds with FXR agonism and inflamma-tion inhibition were further identified in cells transfected with Fxr siRNA and treated with TNF-α.The effects of these dual-function compounds on lipid accumulation and inflammation were evaluated in cells treated with palmitic acid.Results revealed that 17 natural products were predicted via computational molecular docking as potential FXR agonists,with 15 exhibiting a strong affinity for FXR recombinant protein.Nine isoflavone compounds significantly enhanced FXR reporter luciferase activity and the mRNA expressions of Shp and Ostb.Structure-activity relationship analysis indicated that introducing isopropyl or methoxy groups at the C7 position or a methoxy group at the C6 position could enhance the agonistic efficacy of isoflavones.Three compounds(2,6,and 8)were identified as dual-function natural products functioning as FXR agonists and inflammatory inhibitors,while one compound(12)acted as an FXR agonist to inhibit inflammation.These natural products protected hepatocytes against palmitic acid-induced lipid accumulation and in-flammation.In conclusion,compounds 2,6,and 8(genistein,biochanin A,and 7-methoxyisoflavone,respectively)were identified as dual-function bioactive products that transactivate FXR and inhibit inflammation,serving as potential candidates or lead compounds for MASLD therapy.

Objective:To evaluate the efficacy and safety of chimeric antigen receptor T-cell (CAR-T) therapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with Ph-like acute lymphoblastic leukemia (Ph-ALL) .Methods:Patients with Ph-ALL who underwent CAR-T therapy followed by allo-HSCT from March 2018 to August 2023 at the First Affiliated Hospital of Soochow University were included, and their clinical data were retrospectively analyzed.Results:Of the 21 patients, 14 were male and 7 were female. The median age at the time of CAR-T therapy was 22 (6-50) years. Seven patients had ABL1-like rearrangements, and 14 had JAK-STAT rearrangements. Prior to CAR-T therapy, 12 patients experienced hematologic relapse; 7 were multiparameter flow cytometry minimal residual disease (MFC-MRD) -positive and 2 were MFC-MRD-negative. CAR-T cells were derived from patients’ autologous lymphocytes. Nine patients were treated with CD19 CAR-T cells, and 12 were treated with CD19/CD22 CAR-T cells. After assessment on day 28 after CAR-T therapy, 95.2% of the patients achieved complete remission, with an MRD-negative remission rate of 75%. Nineteen patients developed grade 0–2 cytokine release syndrome (CRS) and 2 patients suffered grade 3 CRS, all cases of which resolved after treatment. All patients underwent allo-HSCT after CAR-T therapy. The median time from CAR-T therapy to allo-HSCT was 63 (38-114) days. Five patients experienced relapse after CAR-T therapy, including four with hematologic relapse and one with molecular relapse. The 3-year overall survival (OS) rates in the ABL1 and JAK-STAT groups were (83.3±15.2) % and (66.6±17.2) %, respectively ( P=0.68) . The 3-year relapse-free survival (RFS) rates were (50.0±20.4) % and (55.6±15.4) % in the ABL1 and JAK-STAT groups, respectively. There was no significant difference in 3-year OS or RFS between the two groups. Conclusions:CAR-T therapy followed by allo-HSCT leads to rapid remission in most patients with Ph-ALL and prolongs leukemia-free survival.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the application effect of the teaching method combining process-oriented-guided inquiry learning (POGIL) theory and micro-class in orthopedic clinical internship.Methods:The 118 interns who completed internship from January 2022 to December 2022 were randomly divided into a control group (58) and an experimental group (60). The control group received traditional teaching, while the experimental group received a teaching method combining POGIL theory and micro-class. After the internship, the two groups were compared for assessment scores (basic theoretical knowledge and professional theoretical knowledge), learning status (classroom performance and self-learning ability), clinical practice ability (Leicester Assessment Scale), and teaching satisfaction. The t-test and chi-square test were performed using SPSS 21.0. Results:After the internship, the assessment scores, classroom performance, self-directed learning ability scores, clinical skills, case writing scores, and teaching satisfaction of the experimental group were all higher than those of the control group ( t/ χ2=5.01, 3.72, 2.20, 6.57, 3.56, 4.52, P<0.05). Conclusions:The teaching method combining POGIL theory and micro-class can enhance the master of theoretical knowledge by orthopedic interns, optimize classroom performance, cultivate self-learning ability, and improve clinical practice ability and teaching satisfaction.

Farnesoid X receptor (FXR) is widely accepted as a promising target for various liver diseases; however, panels of ligands in drug development show limited clinical benefits, without a clear mechanism. Here, we reveal that acetylation initiates and orchestrates FXR nucleocytoplasmic shuttling and then enhances degradation by the cytosolic E3 ligase CHIP under conditions of liver injury, which represents the major culprit that limits the clinical benefits of FXR agonists against liver diseases. Upon inflammatory and apoptotic stimulation, enhanced FXR acetylation at K217, closed to the nuclear location signal, blocks its recognition by importin KPNA3, thereby preventing its nuclear import. Concomitantly, reduced phosphorylation at T442 within the nuclear export signals promotes its recognition by exportin CRM1, and thereby facilitating FXR export to the cytosol. Acetylation governs nucleocytoplasmic shuttling of FXR, resulting in enhanced cytosolic retention of FXR that is amenable to degradation by CHIP. SIRT1 activators reduce FXR acetylation and prevent its cytosolic degradation. More importantly, SIRT1 activators synergize with FXR agonists in combating acute and chronic liver injuries. In conclusion, these findings innovate a promising strategy to develop therapeutics against liver diseases by combining SIRT1 activators and FXR agonists.

Objective:To observe the efficacy and safety of decitabine combined with chemotherapy in treatment of relapsed/refractory T lymphoblastic lymphoma/leukemia (T-LBL/ALL) with TP53 mutation.Methods:The clinical data of a T-LBL/ALL patient with TP53 mutation who had recurrence after allogeneic hematopoietic stem cell transplantation (allo-HSCT) treated with decitabine combined with chemotherapy in the First Affiliated Hospital of Soochow University in June 2018 were retrospectively analyzed and the relevant literature was reviewed.Results:The patient, a 42-year-old male, diagnosed as T-LBL/ALL with TP53 mutation by comprehensive examination underwent sibling-matched donor allo-HSCT after a second complete remission. The patient relapsed 8 months later and was treated with decitabine combined with CLAG regimen to achieve complete remission again. And then, he had leukemia-free survival until now through maintenance treatment with decitabine.Conclusion:Decitabine combined with chemotherapy may be a safe and effective treatment option for relapsed T-LBL/ALL patients with TP53 mutation after allo-HSCT.
