The polymerase 1 and transcript release factor (PTRF)-cytoplasmic phospholipase A2 (cPLA2) phospholipid remodeling pathway facilitates tumor proliferation in glioma. Nevertheless, blockade of this pathway leads to the excessive activation of oncogenic receptors on the plasma membrane and subsequent drug resistance. Here, CD26/dipeptidyl peptidase 4 (DPP4) was identified through screening of CRISPR/Cas9 libraries. Suppressing PTRF-cPLA2 signaling resulted in the activation of the epidermal growth factor receptor (EGFR) pathway through phosphatidylcholine and lysophosphatidylcholine remodeling, which ultimately increased DPP4 transcription. In turn, DPP4 interacted with EGFR and prevented its ubiquitination. Linagliptin, a DPP4 inhibitor, facilitated the degradation of EGFR by blocking its interaction with DPP4. When combined with the cPLA2 inhibitor AACOCF3, it exhibited synergistic effects and led to a decrease in energy metabolism in glioblastoma cells. Subsequent in vivo investigations provided further evidence of a synergistic impact of linagliptin by augmenting the sensitivity of AACOCF3 and strengthening the efficacy of temozolomide. DPP4 serves as a novel target and establishes a constructive feedback loop with EGFR. Linagliptin is a potent inhibitor that promotes EGFR degradation by blocking the DPP4-EGFR interaction. This study presents innovative approaches for treating glioma by combining linagliptin with AACOCF3 and temozolomide.

By aggregating the essence of theories related with depressive syndrome from historical medical practitioners and based on the extensive clinical experience,traditional Chinese medicine(TCM)master Lin Yi proposed the theory of six-stagnation-based breast disease prevention and treatment.She pointed out that the occurrence of breast diseases is related to six stagnations(qi stagnancy,blood stagnancy,phlegm stagnancy,dampness stagnancy,food stagnancy,and fire stagnancy),and the treatment for breast diseases should start from the six stagnations.The development and progression of breast cancer is closely associated with the imbalance of internal environment and the formation of six stagnations,and breast cancer is one of the major diseases suitable for the TCM syndrome differentiation and treatment.For the treatment of early breast cancer,Professor Lin Yi proposed to divide early breast cancer into four stages,namely perioperative period,peri-chemotherapy period,peri-radiotherapy period,and consolidation period.Guided by the theory of six-stagnation-based breast disease prevention and treatment,therapies of soothing the liver,resolving phlegm,removing stasis,clearing heat,eliminating dampness,promoting digestion,fortifying the spleen,and tonifying the kidney are employed to harmonize the internal environment and alleviate symptoms.The theory of six-stagnation-based breast disease prevention and treatment enriches the TCM theory for the prevention and treatment of breast cancer,refines the principles and methods for the staging and syndrome differentiation of early breast cancer,and holds significant implications for enhancing the efficacy of integrated TCM and western medicine in managing early breast cancer.

Objective:
To identify the social ecological factors of individual, family, and physical environments for affecting the development of fundamental motor skills (FMS) among overweight and obese children, so as to provide a basis for the future intervention design and policy making.
Methods:
From March to April 2022, one public primary school was recruited from each of the 4 main urban areas in Shijiazhuang, and a total of 425 children in schools were recruited for data collection including individual, family, physical environmental factors, by using a stratified cluster random sampling approach. Test of Gross Motor Development-Third Edition (TGMD-3) was used to evaluate children s FMS. Hierarchical linear regression model was employed to analysis the associations between the 18 factors for individual, family, and physical environments, and the FMS of overweight and obese children.
Results:
Individual level including the child s age, gender and sleep duration, and family level including high family economic level, parental support for physical activity, and the physical activity environment surrounding the family and community were consistent predictors of movement skills ( B =0.422, -1.972, 0.014, 0.045, 1.042, 0.827, 1.898), ball skills ( B =0.858, 3.953, 0.013, 0.092, 2.141, 1.173, 1.954), and composite skills ( B =1.305, 1.915, 0.028, 0.142, 3.091, 1.962, 3.879) among overweight and obese children ( P <0.05). Furthermore, child s body mass index (BMI), moderate to vigorous physical activity, perceived motor competence, pleasure of exercise,as well as BMI and physical activity levels of their primary caregiver, were associated with different types of FMS ( P <0.05). Individual, family, and physical environmental factors had moderate to high predictive explanatory power for FMS among overweight and obese children ( 2=0.69, 0.75, 0.93, P <0.01).
Conclusions
The factors influencing the development of FMS in overweight and obese children are multifaceted, with individual, family, and physical environment factors all playing significant roles.Corresponding measures should be actively taken to improve FMS in overweight and obese children.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To establish a rapid pipeline for whole genome sequencing of Chikungunya virus (CHIKV) by combining imbricated multiplex-PCR amplification and Illumina high-throughput sequencing platform.Methods:The primary reference sequences of CHIKV were downloaded from the National Center for Biotechnology Information (NCBI) database, covering all genotypes of CHIKV. After multiple alignments using the Mafft software and phylogenetic analysis, the 20 CHIKV references were selected for primer design. The Primal Scheme tool and Geneious Prime software were used to design, evaluate and optimize the primer panel. Finally, seven CHIKV-positive samples were involved in the validation of the primer panel.Results:All the amplicons of the designed panel were generated successfully. The consensuses generated from the mapping results could cover 100.00% of the coding region of the CHIKV genome when the Ct-value of the sample was less than 33, as the percentage would decrease to 99.38% when the Ct-value reached 35. The mapping percentage could be increased by 5.70%-25.43% when using the stepwise correction mapping strategy.Conclusion:The multiplex-PCR amplification method for CHIKV whole genome sequencing is relatively simple and convenient, which only requires two tubes of PCR amplification and performs well on CHIKV-positive clinical samples with different concentration levels of virus.
