CO-002

The thermal power industry is a major anthropogenic source of emissions in China, significantly contributing to the release of carbon dioxide (CO₂) and air pollutants. This study evaluated emission reduction potential under various scenarios by establishing the latest, real-monitored, and unit-level emissions database of particulate matter (PM), sulfur dioxide (SO₂), nitrogen oxide (NOx), and CO₂ for Chinese thermal power industry during 2021-2023. The results indicate that, during 2022-2023, the concentrations of PM, SO₂, NOx, and CO₂ decreased by 1.40 %, 0.83 %, 0.94 %, and 36.93 %, respectively. However, these reductions were insufficient to offset the impact of increased fuel consumption, leading to a rise in emissions of PM, SO₂, NOx, and CO₂ by 21.42 %, 13.43 %, 17.49 %, and 5.28 %, respectively. In 2023, the national average Synergy Indices for CO₂-PM, CO₂-SO₂, and CO₂-NOx were only 0.02, 0.01, and 0.01, indicating weak synergistic effects between CO₂ and air pollutant. This low coordination level is mainly caused by the continued implementation of separate and uncoordinated management frameworks for carbon and air pollutants in most provinces. Furthermore, clean energy substitution was identified as the most effective measure for emission reduction, with potential decreases of 66.45 %, 70.16 %, 70.43 %, and 9.80 % for PM, SO₂, NOx, and CO₂, respectively. This study provides a practical roadmap for the development of synergistic mitigation policies and offers valuable insights for other countries, such as India, in addressing climate change challenges within the energy sector.

Patients with hypertrophic scarring tend to experience recurrence after treatment, which often occurs in areas of the body with high skin tension.

To evaluate better treatments aimed at reducing the risk of scar recurrence in areas of high skin tension.

Patients were randomly divided into the following three treatment groups: botulinum toxin type A (BTA) via dual‐plane micro‐drop injections, triamcinolone acetonide (TAC) suspension, and CO2 via fractional CO2 laser. Interventions were implemented in all three groups once a month for three consecutive sessions. After the final treatment, scarring was evaluated at 1, 3, 6, 12, and 24 months using the Patient and Observer Scar Assessment Scale (POSAS).

The 3‐month POSAS score for each scar indicator in the treatment groups was significantly lower than that in the preoperative groups (p < 0.001). The scar score in the TAC group decreased at 3 months and increased thereafter. For other groups, the scar score continually decreased at all time points according to the Patient Scar Assessment Scale. Based on the Observer Scar Assessment Scale, the scar score continuously decreased at all time points in the BTA group; in the TAC group, it decreased at 1 month and increased thereafter; and in the CO2 group, the scar score decreased at 3 months and subsequently stabilized.

All three treatment methods were effective. However, the BTA group experienced a reduced risk of scar recurrence and maintained long‐term treatment effects.
