Serious diseases,particularly cancer,consistently pose significant threats to both national health and economic development[1].The cancer diagnosis methods such as fluorescent probes [2,3],as well as treatment techniques including photodynamic treatments [4] and targeted drugs [5] have attracted much attention in recent years.The development and practical application of these methods have become focal points within research works.Based on this,the 3rdXihua Chemistry and Biomedicine Forum (XHCBF)was successfully convened by Xihua University in Chengdu from 3 to 6 July,2023.

XHCBF serves as an academic platform for experts,scholars and students,aimed at deepening research insights,fostering exchange and collaboration,and accelerating interdisciplinary development across chemistry,medicine,biology,materials and related disciplines.XHCBF was established in Chengdu in 2021 by Xiaoqi Yu,together with Cheng Yang,Zhenju Jiang,Zhouyu Wang and Leyong Wang.The name of the forum "Xihua" carries three meanings: (1)The forum would be held in the beautiful Xihua University;(2) A representation of western China,hoping to form a brand and promote the development of chemical and biopharmaceutical industry in western China;(3) To foster connections with scientists in diverse regions within China.The Editorial Board for organic chemistry ofChin.Chem.Lett.(CCL) played a pivotal role in the preparation of the conference,with their guidance and involvement proving instrumental in the success of the 1stXHCBF.

The 2ndXHCBF was held in August 2022,when it was a critical period to fight against the COVID-2019 pandemic.Under the guidance of Prof.Xiaoqi Yu and Prof.Zhouyu Wang,the organizing committee surmounted various challenges to collaboratively present the second forum alongside the Asymmetric Synthesis and Chiral technology Key Laboratory of Sichuan Province.The theme of the second forum was around Fine Chemistry and Green Synthesis.The success of the last two forum gradually increased the influence of the forum and improve its scholarly platform.

Therefore,the 3rdXHCBF continued its tradition in Chengdu from 3 to 6 July,2023.The theme of this forum was the Diagnosis and Treatment of Diseases.Prof.Zhouyu Wang and her team organized the forum,with co-hosting support from the Sichuan Engineering Research Center for Molecular Targeted Diagnostic & Therapeutic Drugs,Asymmetric Synthesis and Chiral Technology Key Laboratory of Sichuan Province,Research and Application of Small Organic Chiral Molecules Key Laboratory of Yibin City,and Experimental Teaching Center of Chemistry(Xihua University)-Sichuan Experimental Teaching Demonstration Center (Fig.1).Academician Fen-er Chen delivered the opening speech for the forum.The forum featured 20 invited talks,presenting the latest research findings spanning the various areas of fluorescent probes,photodynamic therapies and targeted drugs.

In addition,the forum also organized sub-forums tailored for young teachers and graduate students,thereby fostering a robust platform for communication and exchange amongst them.The sustainable increase in attendance well reflects the growing influence of chemistry and biomedicine in China,with a great number of researchers engaging in this vibrant Diagnosis and Treatment of Diseases field.We express our appreciations to all lecturers whose exceptional presentations enriched the forum,as well as to the scholars and graduate students whose attendance contributed to its success.

Lastly,we express our sincere appreciations toCCL.The XHCBF conference committee and Editorial Board ofCCLhave established a strategic cooperation relationship,envisioning a series of interconnected academic activities spanning diverse fields.
