| 1 | Electrochemical Oxidative C-H Sulfenylation of Imidazopyridines with Hydrogen Evolution显示文摘Summary of main observation and conclusion Selective oxidative C-H sulfenylation of imidazopyridine heterocycles is achieved using an undivided electrolytic cell.The reaction avoids the use of stoichiometric amount of external chemical oxidant and produces hydrogen gas as the only byproduct. Both aryl and aliphatic thiols demonstrate good reactivity for C-S bond formation. | Yong Yuan Yangmin Cao Jin qiao Yueping Lin Xiaomei Jiang Yaqing Weng Shan Tang Aiwen Lei | 2019 | Chinese Journal of Chemistry2019，37，1： | 5 |

| 5 | Predictors of pathologic complete response in patients with residual flat mucosal lesions after neoadjuvant chemoradiotherapy for locally advanced rectal cancer显示文摘Objective:The accurate prediction of tumor response to neoadjuvant chemoradiotherapy(nCRT)remains challenging.Few studies have investigated pathologic complete response(ypCR)prediction in patients with residual flat mucosal lesions after treatment.This study aimed to identify variables for predicting ypCR in patients with residual flat mucosal lesions after nCRT for locally advanced rectal cancer(LARC).Methods:Data of patients with residual flat mucosal lesions after nCRT who underwent radical resection between 2009 and 2015 were retrospectively collected from the LARC database at Peking University Cancer Hospital.Univariate and multivariate analyses of the association between clinicopathological factors and ypCR were performed,and a nomogram was constructed by incorporating the significant predictors.Results:Of the 246 patients with residual flat mucosal lesions included in the final analysis,56(22.8%)had ypCR.Univariate and multivariate analyses showed that pretreatment cT stage(pre-cT)≤T2(P=0.016),magnetic resonance tumor regression grade(MR-TRG)1-3(P=0.001)and residual mucosal lesion depth=0 mm(P<0.001)were associated with a higher rate of ypCR.A nomogram was developed with a concordance index(C-index)of0.759 and the calibration curve showed that the nomogram model had good predictive consistency.The follow-up time ranged from 3.0 to 113.3 months,with a median follow-up time of 63.77 months.The multivariate Cox regression model showed that the four variables in the nomogram model were not risk factors for disease-free survival(DFS)or overall survival(OS).Conclusions:Completely flat mucosa,early cT stage and good MR-TRG were predictive factors for ypCR instead of DFS or OS in patients with LARC with residual flat mucosal lesions after nCRT.Endoscopic mucosal re-evaluation before surgery is important,as it may contribute to decision-making and facilitate nonoperative management or organ preservation. | Changlong Li Zhen Guan Yi Zhao Tingting Sun Zhongwu Li Weihu Wang Zhexuan Li Lin Wang Aiwen Wu | 2022 | Chinese Journal of Cancer Research2022，34，4： | 1 |
| 6 | Regioselective electrochemical radical cascade cyclization of internal alkynes to selenated and trifluoromethylated dihydropyran显示文摘Dihydropyran(DHP)compounds are not only found in natural products and bioactive molecules,but also serve as important precursors in organic synthesis.Nonetheless,traditional methods for the construction of such compounds are usually limited to disubstituted DHPs.To address this synthetic challenge,reported here is an efficient electrochemical strategy toward the selenated and trifluoromethylated DHP compounds.The reaction proceeded smoothly under mild electrolysis conditions.The broad substrate scope(>50 examples)and scalable synthesis demonstrated the complexity-building potential of the strategy.Initial mechanistic studies reveal that cyclization may involve a radical process.This protocol may promote the further development of diversified synthesis of multi-substituted dihydropyran. | Mingming Yu Tiantian Huang Lin Zhang Muhammad Shabbir Yuhan Gao Yi-Hung Chen Hong Yi Aiwen Lei | 2023 | Science China Chemistry2023，66，11： | 0 |
| 7 | Chinese guidelines for the application of colon cancer staging recognition systems based on artificial intelligence platforms (2021)显示文摘The incidence and mortality of colon cancer in China are increasing each year.At present,treatment selection for colon cancer patients mainly depends on imaging results,which require a large number of radiologists to interpret.In China,there is a shortage and uneven distribution of experienced radiologists,which leads to delays and bias in the evaluation of imaging data.Based on these considerations,the Colorectal Surgery Group of the Surgery Branch of the Chinese Medical Association in collaboration with experts at Beihang University has independently developed an artificial intelligence(AI)-based recognition system for the preoperative determination of colon cancer stage to partially replace the work of and relieve the pressure on radiologists.These guidelines aim to standardize the use of AI-based recognition systems in the preoperative staging of colon cancer and guide their clinical application. | Yun Lu Shuai Li Yuan Gao Yong Dai Bo Feng Fanghai Han Jiagang Han Jingjing He Xinxiang Li Guole Lin Qian Liu Guiying Wang Quan Wang Zhenning Wang Zheng Wang Aiwen Wu Bin Wu Yingchi Yang Hongwei Yao Wei Zhang Jianping Zhou Aimin Hao Zhongtao Zhang 无 | 2021 | Intelligent Medicine2021，1，1： | 0 |
| 8 | Examined lymph node numbers influence prognosis in rectal cancer treated with neoadjuvant therapy显示文摘Background:The number of lymph nodes examined(LNe)is often insufficient in patients with rectal cancer(RC)treated with neoadjuvant therapy;however,its prognostic value remains controversial.Thus,we retrospectively explored whether LNe had an influence on staging and prognosis and investigated whether there was a cut-off value for better prognosis in patients with RC treated with neoadjuvant therapy.Methods:Data were collected from seven prospective hospital databases in China from July 2002 to May 2018.Binary logistic regression models were used to predict lymph node metastasis.The cut-off value for LNe was determined using X-tile 3.6.1.Survival outcomes and risk factors were analyzed using the log-rank test and Cox regression model.Results:A total of 482 patients were included,of whom 459 had complete overall survival(OS)information.Using the percentile method,the total number of lymph nodes examined(TLNe)was 14-16(40th-60th percentile),and the proportion of patients with lymph node metastasis reached a maximum of 48.1%.Cox multivariate analysis showed that the odds ratio(OR)remained the highest when TLNe was 14-16(OR=3.379,P=0.003).The 3-year and 5-year OS were 85.4% and 77.8%,respectively.Negative lymph nodes examined(NLNe)of≤6 was an independent risk factor for 3-year and 5-year OS(3-year OS 71.1%vs.85.9%,P=0.004;5-year OS 66.3%vs.74.3%,P=0.035).Subgroup analysis for patients with ypN+showed that higher 3-year and 5-year OS were achieved when the TLNe was>10,78.8%vs.54.0%(P=0.005),and 60.8%vs.36.0%(P=0.012),respectively.Patients with ypN0M0 had a higher 5-year OS when the TLNe was>19(P=0.055).Conclusion:The TLNe and NLNe influenced the staging accuracy and demonstrated prognostic value in patients with RC treated with neoadjuvant therapy. | Liyu Zhu Lin Wang Zhidong Gao Yujian Zeng Kaixiong Tao Quan Wang Xinming Li Huanhu Zhang Zhanlong Shen Jing Zhou Kai Shen Yingjiang Ye Aiwen Wu | 2023 | Cancer Pathogenesis and Therapy2023，1，3： | 0 |
