The Qinghai-Tibet Plateau is an important ecological security barrier in China. Considering the rich local waste biomass with a single treatment method and low level of resource utilization, biochar utilization of solid waste biomass can be carried out based on the research that biochar has abundant material sources. According to the application methods of various types of solid waste resources that have not been carried out, this review analyzes and discusses various types of waste biomass resources in the plateau region, such as sewage plant sludge, food waste, green leaves, barley straw, yak manure, and the unique Tibetan tea and Tibetan medicine residue waste, and reviews the biochar methods and applications for similar raw materials at home and abroad. Further, the technical outlook of solar pyrolysis technology and UV radiation modification technology and the development of hybrid pyrolysis to enhance the performance of biochar materials and heavy metal passivation are proposed by utilizing the solar energy resources of the Tibetan Plateau. Collectively, it provides a reference for prevention and restoration methods for the fragile ecological environment of the Qinghai-Tibet Plateau, reduces the pressure of waste disposal in the region, and realizes the resource utilization of waste.

Background: Pelvic exenteration (PE) is often the only curative treatment option for selected locally advanced and locally recurrent colorectal cancer associated with significant morbidity. Open and laparoscopic approaches were accepted for this procedure., Objective: This study aimed to examine the Chinese patient-reported outcomes (PROs) and health-related quality of life (HRQoL) after PE., Methods: A total of 122 enrolled participants were asked to complete PROs at baseline and 1, 3, 6, 9 and 12 months after PE. PROs included seven symptoms from the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). The HRQoL was assessed using the Functional Assessment of Cancer Therapy-Colorectal (FACT-C)., Results: The overall postoperative complication rate was 41.0%. Patients experienced lower physical and functional well-being and FACT-C 1 month after surgery, then gradually recovered. The FACT-C score returned to baseline 9 months after surgery. Social and emotional well-being did not show signs of recovery until 6 months after the surgical procedure, and did not fully return to baseline until 12 months post-surgery. Symptom rates of insomnia, anxiety, discouragement, and sadness (composite score >0) did not improve significantly from baseline until 12 months after surgery., Conclusions: PE is a feasible treatment choice for locally advanced primary and recurrent colorectal cancer. Social, psychological, and emotional recovery in the Chinese population after PE tends to be slower compared with the physical condition., (© 2024. Society of Surgical Oncology.)
