Purpose: Renal cell carcinoma (RCC), exhibiting remarkable heterogeneity, can be highly infiltrated by regulatory T cells (Tregs). However, the relationship between Treg and the heterogeneity of RCC remains to be explored.
Methods: We acquired single-cell RNA-seq profiles and 537 bulk RNA-seq profiles of TCGA-KIRC cohort.

Purpose: China has developed and widely piloted a new case-based payment, ie, the "Diagnosis-Intervention Packet" (DIP) payment, which has a granular classification system. We evaluated the impact of DIP payment on the quality of care in a large pilot city in China and explored potential mechanisms of quality change.
Methods: The city started to implement DIP payment with a hospital-level cap on July 1, 2019.

Article Synopsis
- The study explores the growing trend of post-bariatric lipoabdominoplasty in China, addressing the challenges of significant weight loss and skin laxity in patients.
- Over a five-year period, 23 patients underwent the procedure which included various surgical techniques, resulting in generally favorable aesthetic outcomes but a notable complication rate of 34.8%.
- The main complication was hypertrophic scarring, and the results suggest that traditional lipoabdominoplasty may be more suitable for Chinese patients compared to alternative surgical options.
Article Synopsis
- Cooperation is seen as a selfless act where individuals contribute to public goods for the benefit of their communities, but it struggles to persist because defecting often yields better individual rewards.
- Recent studies are examining how shifting environments and player strategies affect cooperation in complex social networks, but not enough focus is given to the role of degree heterogeneity in these networks.
- The research models a Public Goods Game that shows that higher cooperation can be achieved with favorable initial environmental factors, but if social network heterogeneity becomes too extreme, it can actually reduce cooperation levels.

Background: The chest, with its high skin tension, is prone to keloids and has a high relapse rate. Surgical excision of keloids combined with radiation therapy significantly reduces the recurrence rate. For larger chest keloids (3-10 cm), intercostal artery perforator propeller flap can be used to reduce tension.
