AIM:The aim of this study was to explore the effects of Yiqi-Yangyin-Quyu prescription(YP)on skeletal muscle injury and related metabolic disorders in mice with Sj?gren syndrome(SS),and to clarify the role of hy-droxyacyl-CoA dehydrogenase trifunctional multienzyme complex subunit beta(Hadhb)in mediating the effect of YP on skeletal muscle in SS.METHODS:The SS mice underwent YP treatment for 8 weeks.The morphological changes of the submandibular gland and muscle tissue were examined using hematoxylin-eosin staining.The mitochondrial status in mus-cle tissue was assessed through transmission electron microscopy.Additionally,combined transcriptome and proteome se-quencing was conducted on skeletal muscle samples.The omics sequencing results were validated by RT-qPCR.Immuno-fluorescence was used to confirm the levels of key proteins involved in the P53/peroxisome proliferator-activated receptor gamma(PPARG)signaling pathway.Immunohistochemistry and Western blot were employed to determine the levels of Hadhb key targets.RESULTS:Combined transcriptome and proteome analysis identified 1 523 differentially expressed genes(DEGs)and 182 differentially expressed proteins(DEPs)between the muscle tissue of SS mice(model group)and that of control animals(ICR group),12 of which showed co-differential expression at both transcriptomic and proteomic levels.Compared with model group,1 232 genes and 432 proteins were found to be differentially expressed in the muscle tissue of the mice in YP group.Among these,23 exhibited co-differential expression at both mRNA and protein levels.Gene Ontology(GO)analysis showed that the DEGs and DEPs between ICR and model groups were mainly involved in ener-gy metabolism and fatty acid oxidation,while the DEGs and DEPs between YP and model groups were primarily associated with sarcomere tissue and actin structure.Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis indi-cated that the DEGs and DEPs between ICR and model groups and between model and YP groups were enriched in the com-plement and coagulation cascade and lipid and pyruvate metabolism.The RT-qPCR validation results were consistent with those of the transcriptome analysis.Furthermore,the protein expression of the tumor suppressor P53 was significantly de-creased in YP group compared with model group,whereas that of PPARG was significantly increased.Western blot analy-sis showed that compared with ICR group,Hadhb protein expression was significantly decreased in model group,whereas the opposite trend was detected in YP group.CONCLUSION:The SS-related skeletal muscle damage is closely related to amino acid metabolism disorder and fatty acid degradation.Treatment with YP modulates innate immune defenses,lipid metabolism and energy metabolism in SS,and Hadhb is the key target of YP in SS-related skeletal muscle.

BACKGROUND:Physiotherapy is very important for the recovery after anterior cruciate ligament reconstruction.In recent years,many doctors are optimizing the physical rehabilitation program after anterior cruciate ligament reconstruction.However,there is still a lack of efficient rehabilitation training after anterior cruciate ligament reconstruction. OBJECTIVE:To investigate the effect of vibration therapy combined with suspension training on movement and knee joint function after anterior cruciate ligament reconstruction. METHODS:A total of 80 patients undergoing first unilateral anterior cruciate ligament reconstruction at the Affiliated Sport Hospital,Shanghai University of Sport were randomly divided into vibration therapy group(n=40)and vibration therapy+suspension training group(n=40).In the vibration therapy group,vibration therapy(10 minutes each,once a day,6 times per week)was performed at the 13th week after anterior cruciate ligament reconstruction.Patients in the vibration therapy+suspension training group were treated with vibration therapy(10 minutes each,once a day,6 times per week)and suspension training(twice a week)at the 13th week after anterior cruciate ligament reconstruction.Training in each group was performed for 8 weeks.Knee joint function was evaluated by knee joint Lysholm score before and 8 weeks after training.The symmetry index was evaluated by the isokinetic muscle strength evaluation training system.The balance test system was used to evaluate the average trace error difference of the bilateral multi-axes. RESULTS AND CONCLUSION:Compared with those before training,the knee Lysholm score and the knee extension and flexion symmetry indexes increased(P<0.05),and the average trace error difference decreased after training(P<0.05).Compared with the vibration therapy group,the knee Lysholm score in the vibration therapy+suspension training group increased(P<0.05),the knee extension and knee flexion symmetry index increased(P<0.05),and the average trace error difference decreased(P<0.05).To conclude,compared with vibration therapy training alone,vibration therapy combined with suspension training can significantly improve knee joint function,increase muscle strength and symmetry,and improve balance stability in patients undergoing anterior cruciate ligament reconstruction.

Objective:To investigate the impact of the interval between neoadjuvant immunotherapy combined with chemotherapy(nICT) and surgery on pathological outcomes and prognosis in patients.Methods:This is a retrospective cohort study. A total of 115 patients with locally advanced esophageal squamous cell carcinoma who underwent nICT followed by sequential surgery at Department of Thoracic Surgery, Peking University People′s Hospital or Department of Thoracic Surgery, the First Affiliated Hospital of Zhengzhou University from January 2020 to April 2024 were included. Among them, 99 were male and 16 were female, with an age of ( M(IQR)) 65 (11) years (range:45 to 81 years). All patients received 2 to 6 cycles of paclitaxel plus platinum-based doublet chemotherapy combined with PD-1 immune checkpoint inhibitors. The resectability of tumors was assessed based on CT scans of the chest and abdomen, and surgical approaches included Sweet surgery, Mckeown surgery, and Ivor-Lewis surgery. Patients were divided into a short-interval group (4 to <6 weeks) and a long-interval group (6 to 12 weeks) based on the interval between neoadjuvant immunochemotherapy and surgery. General patient data, surgical details, pathological response, and prognosis were collected and analyzed. Data comparisons were performed using independent sample t-test, Mann-Whitney U test, χ 2 test, or Fisher′s exact test. Multivariate logistic regression analysis was used to identify independent factors influencing pathological complete response (pCR). Survival analysis was conducted using the Kaplan-Meier method and Log-rank test. Results:There were no significant differences in baseline characteristics, neoadjuvant treatment details, surgical outcomes, or postoperative complications between the long-interval group and the short-interval group (all P>0.05). Multivariate Logistic regression analysis revealed that, among clinical factors, interval between neoadjuvant immunochemotherapy and surgery was significantly associated with pCR (long-interval group vs. short-interval group: OR=4.14, 95% CI:1.63 to 10.50, P=0.003). The pCR rate was higher in the long-interval group (43.6% vs. 17.1%, χ2=6.48, P=0.011). Survival analysis showed no significant differences in overall survival ( P=0.094) or disease-free survival ( P=0.840) between the two groups. Conclusion:Appropriately extending the surgical interval after neoadjuvant immunochemotherapy maybe lead to a higher pCR rate, without increasing surgical difficulty or damaging prognosis.

Venous system diseases mainly include varicose veins and venous malformations of lower limbs and the genital system. Most of them are chronic diseases that cause serious clinical symptoms to patients and affect their health and quality of life. Sclerotherapy has become the first-line therapy for venous system diseases. However, there are problems such as incomplete fibrosis and vascular recanalization after sclerotherapy, and improper operation will cause serious adverse consequences. Therefore, exploring a safe and effective sclerotherapy strategy is essential for developing clinically successful sclerotherapy. To solve the above problems, we proposed a new sclerotherapy strategy with a dual mechanism of "vascular damage and plasmin (PLA) system inhibition." We intended to construct a novel cationic surfactant (AEO_x-TA) by reacting tranexamic acid (TA), a parent structure, with fatty alcohol polyoxyethylene ether (AEO_x) by ester bonds. AEO_x-TA could damage vascular endothelium and initiate a coagulation cascade effect to induce thrombus. Furthermore, AEO_x-TA could be degraded by esterase and release the parent drug, TA, which could inhibit the PLA system to inhibit the degradation of thrombus and extracellular matrix and promote the process of vascular fibrosis. In addition, such surfactant-based sclerosants have foam-forming properties, and they can be blended with polyvinyl alcohol (PVA) to prepare a highly stable foam formulation (AEO_x-TA/P), which can achieve a precise drug delivery and prolonged drug retention time, thereby improving drug efficacy and reducing the risk of ectopic embolism. Overall, the novel cationic surfactant AEO_x-TA provides a new avenue to resolve the bottleneck: surfactant sclerosants' efficiency is relatively low in the current sclerotherapy.

Diminished ovarian reserve (DOR) refers to the decrease in the number of follicles and the quality of oocytes that appear prematurely before menopause. The pathogenesis of DOR is not yet fully understood, and clinical treatment lacks efficient methods, making it an urgent problem to be solved in the field of reproductive medicine. Acupuncture and moxibustion has been gradually popularized in the world for the treatment of gynecological diseases due to its advantages such as convenient operation, good curative effect and quick effect. With the rapid development of omics technology, molecular targets related to DOR pathogenesis (proteins, nucleic acids, receptors, etc.) are gradually recognized. In this review, we plan to make a summary from the perspective of the target of acupuncture and moxibustion treatment of DOR, in order to provide a reliable basis for the clinical treatment of DOR.

A 52-year-old male patient with small cell lung cancer developed symptoms of systemic skin redness, edema, and blisters of varying sizes in multiple parts of the body (neck, chest, and feet) 10 days after receiving chemotherapy with TC regimen (albumin paclitaxel and carboplatin) combined with serplulimab for immunotherapy. It is suspected to be toxic epidermal necrolysis caused by serplulimab. After discontinuing serplulimab and receiving symptomatic treatments such as methylprednisolone, loratadine, ebastine, and adjuvant topical mucosal protection for 10 days, the dermatitis basically subsided and the ruptured blisters were scabby. The patient switched to anlotinib and did not receive immunotherapy again.

The formation of pathological scar has an impact on patients’ normal life and mental health, which is also a thorny problem in plastic surgery. In recent years, the influence mechanism of mechanical tension and signal transduction on wound healing has attracted extensive attention and provides a new idea for the prevention and treatment of pathological scar. This paper reviews the research progress of the influence mechanism of mechanical stretch on wound healing in different stages. In the inflammatory stage, hyperplasia stage and tissue remodeling stage of wound healing, mechanical stretch tension causes biological reactions such as chronic inflammation, fibrosis, angiogenesis, and extracellular matrix remodeling through complex signal transduction and feedback mechanisms, which has an impact on wound healing and scar formation. Mechanical stretch therapy for wound healing and scar formation has also achieved certain result in clinical and basic study.
