1Rapid detection of pesticide residues in Chinese herbal medicines by molecularly imprinted membrane electrospray ionization mass spectrometry显示文摘Chinese herbal medicines(CHMs)play an increasingly important role in the field of medicine and affects public health in the world.Although more and more strict has been employed to ensure the quality and safety of CHMs,pesticide residues in CHMs remain a serious issue and are the bottleneck for the global development of CHMs.In this work,we applied molecularly imprinted membrane electrospray mass spectrometry(MIM-ESI MS)for rapid detecting 4 classes of pesticide residues in CHMs,including organophosphorus(OPP),carbamates,pyrethroids and neonicotinoids in CHMs.Compared with our previous ambient ionization method MESI,MIM-ESI is capable of achieving a~50-fold increase in the detection limit of conventional analytical methods owing to the specificity recognition and unique enrichment of MIM.The optimal experimental conditions were determined,and the method was further validated for its sensitivity and specificity.Our data showed that MIM-ESI MS is applicable for the direct quantitation of pesticide residues in CHMs.This detection technology may help to ensure the quality of CHMs in the future.Chunmei Wu Tianyi Li Dongju Li Shanshan Jia Jianmei Huang Haimin Lei Mei Zhang 2021Chinese Chemical Letters2021,32,7:6
2Baicalin and rutin are major constituents in Shuanghuanglian injection involving anaphylactoid reaction显示文摘OBJECTIVE: To identify the constituents in Shuanghuanglian injection(SHLI) that correlate with anaphylactoid reaction.METHODS: Chemical fingerprints of 10 batches SHLI samples were determined by High Performance Liquid Chromatography(HPLC), and further investigated by similarity analysis. Combined with optical microscopy, both anaphylactoid experiments and confirmatory assay were displayed in Rat basophil leukemia cells(RBL-2H3) to obtain the histamine release inducing by SHLI. The content of histamine was tested by Enzyme-Linked Immuno Sorbent As-say method. Partial least squares regression(PLSR)method and HPLC-DAD-ESI-MSntechnology were conducted to analyze constituents in SHLI involving anaphylactoid reaction.RESULTS: The results of spectrum and effect relationships showed that the eight constituents were positively correlated with anaphylactoid reaction.Among which, nearly 90% of them were identified as baicalin and rutin with PLSR and HPLC-DAD-ESI-MSn. This result was in accordance with confirmatory assay on RBL-2H3 cells.CONCLUSION: Baicalin and rutin from SHLI were the main constituents involving anaphylactoid reaction.Zhang Qi Cai Chengke Li Jian Wang Penglong Si Yinchu Ding Nan Gao Jing Zhang Yanqiu Ma Zhiqiang Lei Haimin Li Qiang 2017Journal of Traditional Chinese Medicine2017,37,3:6
3Photoelectrocatalytic activity of an ordered and vertically aligned TiO2 nanorod array/BDD heterojunction electrode显示文摘Rutile TiO_2 nanorod(TiNR) arrays were fabricated on a boron-doped diamond(BDD) substrate by a simple hydrothermal synthesis method. A fluorine-doped tin oxide(FTO) electrode grown with TiNR arrays was also prepared using the same technology for comparison. Field-emission scanning electron microscopy results show that oriented TiNR arrays can grow vertically on the surface of BDD and FTO electrodes. TiNR arrays grown on both electrodes had the same length(3 μm). In comparison with the TiNR/FTO electrode, the TiNR/BDD electrode demonstrated a higher photoelectrocatalytic activity for the degradation of water and organic compounds, which is mostly attributed to the formation of a p-n heterojunction between the TiNR arrays and BDD at high potential, apart from the density of TiNR. A linear relationship between the photoelectrocatalytic current and the organic concentration can be observed on both electrodes. However, the linear range between net photoelectrocatalytic current values and organic compound concentrations for the TiNR/BDD electrode are much greater than those for the TiNR/FTO electrode, which makes the TiNR/BDD electrode a versatile material for the photocatalytic degradation and sensing of organic compounds.Yanhe Han Lei Zhang Yafei Wang Haimin Zhang Shanqing Zhang 2017Science Bulletin2017,62,9:4

5Guidelines for the diagnosis and treatment of acute pancreatitis in China (2021)显示文摘Acute pancreatitis(AP)is a common acute abdominal condition of the digestive system.In recent years,treatment concepts,methods,and strategies for the diagnosis of AP have advanced,and this has played an important role in promoting the standardization of AP diagnosis and treatment and improving the treatment quality of AP patients.On the basis of previous guidelines and expert consensus,this guideline adopts an evidence-based,problem-based expression;synthesizes important clinical research data at home and abroad in the most recent 5 years;and forms 29 recommendations through multidisciplinary expert discussion,including diagnosis,treatment,and follow-up.It is expected to provide evidence support for the treatment of AP in the clinical setting in China.Fei Li Shouwang Cai Feng Cao Rufu Chen Deliang Fu Chunlin Ge Chunyi Hao Jihui Hao Heguang Huang Zhixiang Jian Gang Jin Ang Li Haimin Li Shengping Li Weiqin Li Yixiong Li Tingbo Liang Xubao Liu Wenhui Lou Yi Miao Yiping Mou Chenghong Peng Renyi Qin Chenghao Shao Bei Sun Guang Tan Xiaodong Tian Huaizhi Wang Lei Wang Wei Wang Weilin Wang Junmin Wei Heshui Wu Wenming Wu Zheng Wu Changqing Yan Yinmo Yang Xiaoyu Yin Xianjun Yu Chunhui Yuan Taiping Zhang Yupei Zhao on behalf of the Chinese Pancreatic Surgery Association 2021Journal of Pancreatology2021,4,2:1
6New Metabolic Alterations and A Predictive Marker Pipecolic Acid in Sera for Esophageal Squamous Cell Carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a major histological subtype of esophageal cancer with a poor prognosis.Although several serum metabolomic investigations have been reported,ESCC tumor-associated metabolic alterations and predictive biomarkers in sera have not been defined.Here,we enrolled 34 treatment-naive patients with ESCC and collected their pre-and post-esophagectomy sera together with the sera from 34 healthy volunteers for a metabolomic survey.Our comprehensive analysis identified ESCC tumor-associated metabolic alterations as represented by a panel of 12 serum metabolites.Notably,postoperative abrosia and parenteral nutrition substantially perturbed the serum metabolome.Furthermore,we performed an examination using sera from carcinogen-induced mice at the dysplasia and ESCC stages and identified three ESCC tumor-associated metabolites conserved between mice and humans.Notably,among these metabolites,the level of pipecolic acid was observed to be progressively increased in mouse sera from dysplasia to cancerization,and it could be used to accurately discriminate between mice at the dysplasia stage and healthy control mice.Furthermore,this metabolite is essential for ESCC cells to restrain oxidative stress-induced DNA damage and cell proliferation arrest.Together,this study revealed a panel of 12 ESCC tumor-associated serum metabolites with potential for monitoring therapeutic efficacy and disease relapse,presented evidence for refining parenteral nutrition composition,and highlighted serum pipecolic acid as an attractive biomarker for predicting ESCC tumorigenesis.Lei Liu Jia Wu Minxin Shi Fengying Wang Haimin Lu Jibing Liu Weiqin Chen Guanzhen Yu Dan Liu Jing Yang Qin Luo Yan Ni Xing Jin Xiaoxia Jin Wen-Lian Chen 2022Genomics, Proteomics & Bioinformatics2022,20,4:0
7Consensus of clinical diagnosis and treatment for non-functional pancreatic neuroendocrine neoplasms with diameter<2 cm显示文摘In clinical practice,pancreatic neuroendocrine neoplasms(pNENs)with a diameter smaller than 2 cm are commonly referred to as small pNENs.Due to their generally favorable biological characteristics,the diagnosis and treatment of small pNENs differ from other pNENs and are somewhat controversial.In response to this,the Chinese Pancreatic Surgery Association,Chinese Society of Surgery,Chinese Medical Association have developed a consensus on the diagnosis and treatment of small pNENs,which is based on evidence-based medicine and expert opinions.This consensus covers various topics,including concepts,disease assessment,treatment selection,follow-up,and other relevant aspects.Wu Wenming Cai Shouwang Chen Rufu Fu Deliang Ge Chunlin Hao Chunyi Hao Jihui Huang Heguang Jian Zhixiang Jin Gang Li Fei Li Haimin Li Shengping Li Weiqin LiYixiong Liang Tingbo Liu Xubao Lou Wenhui Miao Yi Mou Yiping Peng Chenghong Qin Renyi Shao Chenghao Sun Bei Tan Guang Wang Huaizhi Wang Lei Wang Wei Wang Weilin Wei Junmin Wu Heshui Wu Zheng Yan Changqing Yang Yinmo Yin Xiaoyu Yu Xianjun Yuan Chunhui Zhao Yupei 2023Journal of Pancreatology2023,6,3:0
8A metal ions-mediated natural small molecules carrier-free injectable hydrogel achieving laser-mediated photo-Fenton-like anticancer therapy by synergy apoptosis/cuproptosis/anti-inflammation显示文摘Tumor microenvironment (TME) plays an important role in the tumorigenesis, proliferation, invasion and metastasis. Thereby developing synergistic anticancer strategies with multiple mechanisms are urgent. Copper is widely used in the treatment of tumor chemodynamic therapy (CDT) due to its excellent laser-mediated photo- Fenton-like reaction. Additionally, copper can induce cell death through cuproptosis, which is a new modality different from the known death mechanisms and has great promise in tumor treatment. Herein, we report a natural small molecules carrier-free injectable hydrogel (NCTD Gel) consisted of Cu2+-mediated self-assembled glycyrrhizic acid (GA) and norcantharidin (NCTD), which are mainly governed by coordination and hydrogen bonds. Under 808 nm laser irradiation, NCTD Gel can produce reactive oxygen species (ROS), consume glutathione (GSH) and overcome hypoxia in TME, leading to synergistically regulate TME via apoptosis, cuproptosis and anti-inflammation. In addition, NCTD Gel’s CDT display high selectivity and good biocompatibility as it relies on the weak acidity and H2O2 overexpression of TME. Notably, NCTD Gel’s components are originated from clinical agents and its preparation process is easy, green and economical, without any excipients. This study provides a new carrier-free hydrogel synergistic antitumor strategy, which has a good prospect in industrial production and clinical transformation.Wenmin Pi Linying Wu Jihui Lu Xiaoyu Lin Xuemei Huang Zhijia Wang Zhihua Yuan Hailing Qiu Jianglan Zhang Haimin Lei Penglong Wang 2023Bioactive Materials2023,,11:0
