Rotator cuff injury is a shoulder disease most commonly seen with the elderly, and as China enters an aging society, the number of patients with rotator cuff injury is rapidly increasing. For patients with poor results of conservative treatment and serious conditions, arthroscopic rotator cuff repair has become the first choice due to less trauma and better efficacy. However, the rehabilitation exercise time required for postoperative functional recovery is long, and at the same time, the existence of a series of complications seriously affects patients' postoperative recovery and quality of life. The purpose of this article is to summarize the complications and preventive measures after arthroscopic rotator cuff injury repair, and to provide help for the diagnosis and treatment of postoperative complications and postoperative rehabilitation.

ObjectiveTo explore the molecular mechanism of Buzhong Yiqitang in attenuating cisplatin resistance in non-small cell lung cancer （NSCLC） by inducing ferroptosis via poly（rC）-binding protein 1 （PCBP1）. MethodsThe serum containing Buzhong Yiqitang was prepared and cisplatin-resistant human non-small cell lung cancer （NSCLC） cells （A549/DDP） were cultured and randomly grouped as follows： Blank （10% blank serum）， model （10% blank serum+20 mg·L^-1 cisplatin）， Buzhong Yiqitang （10% serum containing Buzhong Yiqitang+20 mg·L^-1 cisplatin）， Fe-1 （10% blank serum+20 mg·L^-1 cisplatin+5 μmol·L^-1 Fe-1）， and Buzhong Yiqitang+Fe-1 （10% serum containing Buzhong Yiqitang+20 mg·L^-1 cisplatin+5 μmol·L^-1 Fe-1）. Firstly， PCR Array was used to screen ferroptosis-related genes regulated by Buzhong Yiqitang， and PCBP1 was identified as the target for studying the attenuation of cisplatin resistance by Buzhong Yiqitang. Subsequently， the median inhibitory concentration （IC₅₀） of cisplatin in each group was determined by the cell counting kit-8 （CCK-8） method and the resistance index （RI） was calculated. The ultrastructure of A549/DDP cells in each group was observed by transmission electron microscopy. The protein levels of PCBP1 and glutathione peroxidase 4 （GPX4） were determined by Western blot. The lipid reactive oxygen species （ROS） content in each group was determined by the C11-BODIRY 581/591 fluorescence probe. The ferrous ion assay kit was used to measure the ferrous ion content in each group. The malondialdehyde （MDA） assay kit was used to determine the MDA content in each group. ResultsCompared with model group， the IC₅₀ of cisplatin and the RI of A549/DDP cells decreased in the Buzhong Yiqitang group （P<0.05） but increased in the Fe-1 group （P<0.05）. The IC₅₀ of cisplatin and the RI of A549/DDP cells in the Buzhong Yiqitang+Fe-1 group were lower than those in the Fe-1 group （P<0.05）. Compared with the model group， the Buzhong Yiqitang group showed obvious mitochondrial ferroptosis， while the mitochondrial damage became less obvious after Fe-1 treatment. Compared with that in the Fe-1 group， the mitochondrial ferroptosis was aggravated after the intervention with Buzhong Yiqitang. Compared with blank group， the model group showed down-regulated expression levels of PCBP1 and GPX4 （P<0.05） and increased content of lipid ROS， ferrous ions， and MDA （P<0.05） in A549/DDP cells. Compared with model group， the Buzhong Yiqitang group showed down-regulated expression levels of PCBP1 and GPX4 （P<0.05） and increased content of lipid ROS， ferrous ions， and MDA （P<0.05）， while the Fe-1 group showed up-regulated expression levels of PCBP1 and GPX4 （P<0.05） and reduced content of lipid ROS， ferrous ions， and MDA （P<0.05）. Compared with the Fe-1 group， the Buzhong Yiqitang+Fe-1 group showed down-regulated expression levels of PCBP1 and GPX4 and increased content of lipid ROS， ferrous ions， and MDA （P<0.05）. ConclusionBuzhong Yiqitang attenuated cisplatin resistance in NSCLC by regulating PCBP1 to induce ferroptosis.

BACKGROUND:Osteosarcoma has a complex pathogenesis and a poor prognosis.While advancements in medical technology have led to some improvements in the 5-year survival rate,substantial progress in its treatment has not yet been achieved. OBJECTIVE:To screen key molecular markers in osteosarcoma,analyze their relationship with osteosarcoma treatment drugs,and explore the potential disease mechanisms of osteosarcoma at the molecular level. METHODS:GSE99671 and GSE284259(miRNA)datasets were obtained from the Gene Expression Omnibus database.Differential gene expression analysis and Weighted Gene Co-expression Network Analysis(WGCNA)on GSE99671 were performed.Functional enrichment analysis was conducted using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes separately for the differentially expressed genes and the module genes with the highest positive correlation to the disease.The intersection of these module genes and differentially expressed genes was taken as key genes.A Protein-Protein Interaction network was constructed,and correlation analysis on the key genes was performed using CytoScape software,and hub genes were identified.Hub genes were externally validated using the GSE28425 dataset and text validation was conducted.The drug sensitivity of hub genes was analyzed using the CellMiner database,with a threshold of absolute value of correlation coefficient|R|>0.3 and P<0.05. RESULTS AND CONCLUSION:(1)Differential gene expression analysis identified 529 differentially expressed genes,comprising 177 upregulated and 352 downregulated genes.WGCNA analysis yielded a total of 592 genes with the highest correlation to osteosarcoma.(2)Gene Ontology enrichment results indicated that the development of osteosarcoma may be associated with extracellular matrix,bone cell differentiation and development,human immune regulation,and collagen synthesis and degradation.Kyoto Encyclopedia of Genes and Genomes enrichment results showed the involvement of pathways such as PI3K-Akt signaling pathway,focal adhesion signaling pathway,and immune response in the onset of osteosarcoma.(3)The intersection analysis revealed a total of 59 key genes.Through Protein-Protein Interaction network analysis,8 hub genes were selected,which were LUM,PLOD1,PLOD2,MMP14,COL11A1,THBS2,LEPRE1,and TGFB1,all of which were upregulated.(4)External validation revealed significantly downregulated miRNAs that regulate the hub genes,with hsa-miR-144-3p and hsa-miR-150-5p showing the most significant downregulation.Text validation results demonstrated that the expression of hub genes was consistent with previous research.(5)Drug sensitivity analysis indicated a negative correlation between the activity of methotrexate,6-mercaptopurine,and pazopanib with the mRNA expression of PLOD1,PLOD2,and MMP14.Moreover,zoledronic acid and lapatinib showed a positive correlation with the mRNA expression of PLOD1,LUM,MMP14,PLOD2,and TGFB1.This suggests that zoledronic acid and lapatinib may be potential therapeutic drugs for osteosarcoma,but further validation is required through additional basic experiments and clinical studies.

OBJECTIVE: To observe the efficacy of successive trigger needling combined with conventional acupuncture for cervical spondylosis of qi stagnation and blood stasis. METHODS: A total of 40 patients with cervical spondylosis of qi stagnation and blood stasis were selected, and successive trigger needling at ashi points combined with conventional acupuncture at Baihui (GV20) and bilateral C₃-C₇ Jiaji (EX-B2), Jiquan (HT1), etc. were delivered, once a day, 5 times a week as one course, and 2 courses were required totally. Before treatment and after 1, 2 weeks of treatment, the pain visual analogue scale (VAS) score was observed, and the clinical efficacy was evaluated after treatment. RESULTS: After 1, 2 weeks of treatment, the VAS scores were decreased compared with that before treatment (P<0.001). After treatment, the total effective rate was 97.5% (39/40). CONCLUSION Successive trigger needling combined with conventional acupuncture can effectively treat the cervical spondylosis of qi stagnation and blood stasis, reduce pain and improve the clinical symptoms and signs.

OBJECTIVE: To investigate the feasibility and effectiveness of bilateral facial perforator artery flap in repairing large area defect in middle and lower part of nose. METHODS: The clinical data of 18 patients with large area defect in middle and lower part of nose repaired by bilateral facial perforator artery flap between January 2019 and December 2022 were retrospectively analyzed. Among them, there were 13 males and 5 females, the age ranged from 43 to 81 years, with an average of 63 years. There were 3 cases of nasal trauma, 4 cases of basal cell carcinoma, 8 cases of squamous cell carcinoma, 1 case of lymphoma, and 2 cases of large area solar keratosis. The size of the defect ranged from 3.0 cm×3.0 cm to 4.5 cm×4.0 cm; the size of unilateral flap ranged from 3.0 cm×1.3 cm to 3.5 cm×2.0 cm, and the size of bilateral flaps ranged from 3.3 cm×2.6 cm to 4.5 cm×4.0 cm. RESULTS: One patient developed skin flap necrosis after operation, and a frontal skin flap was used to repair the wound; 1 case gradually improved after removing some sutures due to venous congestion in the skin flap, and the wound healing was delayed after dressing change; the remaining 16 cases of bilateral facial perforator artery flaps survived well and all wounds healed by first intention, without any "cat ear" malformation. All 18 patients had first intention healing in the donor area, leaving linear scars without obvious scar hyperplasia, and no facial organ displacement. All patients were followed up 3-12 months, with an average of 6 months. Due to the appropriate thickness of the flap, none of the 18 patients underwent secondary flap thinning surgery. All flaps had good blood circulation, similar texture and color to surrounding tissues, symmetrical bilateral nasolabial sulcus, and high patient satisfaction. CONCLUSION The bilateral facial perforator artery flaps for repairing large area defect in middle and lower part of nose can achieve good appearance and function, and the operation is relatively simple, with high patient satisfaction.
