Membrane technology has become one of the most promising separation technologies for its energy saving, high separation efficiency, environmental friendliness, and economic feasibility. Covalent organic frameworks(COFs) with intrinsically high porosity, controllable pore size, uniform pore size distribution and long-range ordered channel structure, have emerged as next-generation materials to fabricate advanced separation membranes. This feature article summarizes some latest studies in the development of pure COF membranes in our lab, including their fabrication and applications in chemical separations. Finally, current challenges facing high-performance COF separation membranes are discussed.

Department of Cancer Center Peking Union Medical College Hospital Chinese Academy of Medical Sciences

Objective: This study evaluated the safety and efficacy of an anti-epidermal growth factor receptor(EGFR) antibody(SCT200) and an anti-programmed cell death 1(PD-1) antibody(SCT-I10A) as third-line or subsequent therapies in patients with rat sarcoma viral oncogene(RAS)/v-raf murine sarcoma viral oncogene homolog B(BRAF) wild-type(wt) metastatic colorectal cancer(mCRC).Methods: We conducted a multicenter, open-label, phase Ib clinical trial. Patients with histologically confirmed RAS/BRAF wt m CRC with more than two lines of treatment were enrolled and treated with SCT-I10A and SCT200. The primary endpoints were the objective response rate(ORR) and safety. The secondary endpoints included disease control rate(DCR), progression-free survival(PFS), and overall survival(OS).Results: Twenty-one patients were enrolled in the study through January 28, 2023. The ORR was 28.57% and the DCR was 85.71%(18/21). The median PFS and OS were 4.14 and 12.84 months, respectively. The treatment-related adverse events(TRAEs) were tolerable. Moreover, compared with the monotherapy cohort from our previous phase I study evaluating SCT200 for RAS/BRAF wt m CRC in a third-line setting, no significant improvements in PFS and OS were observed in the combination ***: SCT200 combined with SCT-I10A demonstrated promising efficacy in previously treated RAS/BRAF wt m CRC patients with an acceptable safety profile. Further head-to-head studies with larger sample sizes are needed to validate whether the efficacy and safety of combined anti-EGFR and anti-PD-1 therapy are superior to anti-EGFR monotherapy in the third-line setting.(Registration No. NCT04229537).

As Professor Jiaxi Lu,the former president of the Chinese Academy of Sciences(CAS),said,“Academic journals are both the‘tail’and the‘head’of a dragon”[1].Professor Zuoyan Zhu,former editor-in-chief of both Science China and Science Bulletin,also once said,“Let Chinese scientific journals grow along with scientific research in China”[2].Academic journals are important carriers for the exchange and dissemination of innovation and achievement in science and are important gardens for the training of scientific talent;also,they play an important role in carrying out an evaluation of academic *** journals are an important component of the academic journal sphere,not only because they account for onethird of academic journals but also because they are directly related to human health。
