New quality productivity force is an advanced form of productive force that is innovation-driven, characterized by high technology, high efficiency, and high quality. It aligns with the new development philosophy and represents an advanced state of productivity. Within the medical sphere, this concept is epitomized by the progressive evolution of surgical instruments and techniques. In recent years, the rapid development of new quality productivity forces in the medical field has generated significant anticipation for innovations in urological robotic surgery instruments and techniques. Advancements in domestically produced robotic surgery systems, remote robotic surgery, single-port robotic surgery, and pediatric-specific robotic surgery exemplify the critical application of new quality productivity forces in urology. The integration of artificial intelligence, haptic feedback technology, and sensory enhancement technologies has further enhanced the safety and precision of surgeries. Driven by these new quality productivity forces, the development of urological robotic surgery instruments and techniques has reached a new milestone, potentially setting a new gold standard for urological surgeries and providing patients with safer, more efficient, and personalized medical care. However, certain emerging technologies still face challenges in their application, necessitating further research and clinical validation.

Aging, a process of functional decline with the increase of chronological age, is a major risk factor for chronic diseases. Aging shows significant individual differences, which is influenced by both genetic and environmental factors. Accurate measurement of physiological age helps identify individuals with accelerated aging and those at high risk for chronic diseases and mortality, which would promote individual health management and precision medicine for healthy aging. In this paper, we summarize the omics-based aging clocks and discuss their current and future applications.

Objective: Explore the expression pattern of transcription factor activator protein 2C (TFAP2C) and identify the roles of Tfap2c during tooth development. Methods: Real-time fluorescence quantitative PCR (RT-qPCR) was used to analyze the relative expression level of Tfap2c in various organs of embryonic day(E)14.5 mouse embryos and mouse molar germs at E12.5-E18.5 and postnatal day (P)0-P7. The expression position of Tfap2c in mouse molar germs was demonstrated by frozen section immunofluorescence staining. Cultured mandibular molar germs were transfected with control small interfering RNA (siRNA) or Tfap2c siRNA to evaluate the effect of Tfap2c on tooth molar germs development, and RT-qPCR was used to detect the relative expression level of genes related to odontoblast expression. Dental mesenchymal cells were isolated from E14.5 molar germs and transfected with control siRNA or Tfap2c siRNA, cell counting kit 8 (CCK-8) and scratch healing test were applied to detect dental mesenchymal cell viability and migration. Results: Tfap2c was highly expressed in the early development period of mouse molar germs. Tfap2c was expressed in the epithelial and mesenchymal tissues of E13.5 mouse molar germs and there was no significant difference of relative expression of Tfap2c between them ( t =1.06, P =0.472). Tfap2c was expressed in mesenchymal tissues of E14.5 mouse molar germs and the relative expression of Tfap2c in mesenchymal tissues was significantly higher than epithelial tissues ( t =37.29, P <0.0001). For molar germs transfected with Tfap2c siRNA, the relative height of cusps (0.708±0.171) and the ratio of cusp height and crown height (0.321±0.068) was significantly lower than control group (1.000±0.287 and 0.483±0.166) ( t =2.79, P =0.012; t =2.85, P =0.015). But there was no significant difference in relative height (1.078±0.206, 0.993±0.254, t =0.83, P =0.419)and relative width (1.000±0.116, 0.999±0.122, t =0.01, P =0.992) of crowns between two groups. The relative expression level of genes related to odontoblast expression was decreased (Dspp: t =15.33, P <0.001; Dmp1: t =13.81, P <0.001). Tfap2c siRNA hinders cell migration in dental mesenchymal cells ( t =29.86, P =0.001), but there was no significant difference in CCK-8 absorbance value between two groups. The relative expression level of genes related to odontoblast expression was also decreased in dental mesenchymal cells transfected with Tfap2c siRNA (Dspp: t =3.86, P =0.031; Dmp1; t =4.36, P =0.022). Conclusions: Tfap2c highly expressed in the early morphogenesis period of mouse molar germs, mainly in mesenchymal tissues. Tfap2c affected the cusps formation of mouse molar germs and migration of dental mesenchymal cells.
