| 1 | A botanical medicine dragon’s blood exhibited clinical antithrombosis efficacy similar to low molecular weight heparin显示文摘Deep vein thrombosis(DVT)is a common complication following traumatic fracture with a 0.5%–1%annual incidence.Low molecular weight heparin(LMWH)is the most commonly used anticoagulation drug for DVT prevention,but treatment with LMWH is invasive.Our aim is to compare the antithrombotic effect of dragon’s blood,an oral botanical anticoagulant medicine approved by the Chinese FDA,with LMWH in patients undergoing hip fracture surgery and to explore the molecular mechanisms of anticoagulation treatment.Our study recruited patients and divided them into LMWH and dragon’s blood treatment group.Coagulation index tests,Doppler ultrasound and mRNA sequencing were performed before and after anticoagulation therapy.There was no significant difference in postoperative DVT incidence between the two groups(23.1%versus 15.4%,P=0.694).D-dimer(D-D)and fibrinogen degradation product(FDP)showed significant reductions in both groups after anticoagulation treatments.We identified SLC4A1,PROS1,PRKAR2B and seven other genes as being differentially expressed during anticoagulation therapy in both groups.Genes correlated with coagulation indexes were also identified.Dragon’s blood and LMWH showed similar effects on DVT and produced similar gene expression changes in patients undergoing hip fracture surgery,indicating that dragon’s blood is a more convenient antithrombosis medicine(oral)than LMWH(hypodermic injection). | Jiangbin Liang Song Mei Xiangyu Qiao Wei Pan Yan Zhao Shaohui Shi Yaling Zhai Haizhao Wen Guoping Wu Chengyu Jiang | 2021 | Science China(Life Sciences)2021，64，10： | 4 |
| 2 | Electrosynthsis of large polypyrrole films by multi-potential steps method显示文摘Polypyrrole (PPy) films were prepared by multi-potential steps polymerization in an aqueous pyrrole solution, with lithium perchlorate and oxalic acid as supporting electrolytes. Morphology and structure of PPy films were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Electrochemical behaviors of PPy films were studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results show that multi-potential steps polymerization improves the conductivity of PPy films and large polymer films can be peeled off easily from the electrode without cracking. Lithium perchlorate and oxalic acid provide appropriate dopants for PPy polymerization. It was observed that the polymerization time and the current density have a crucial influence on the surface morphology of PPy films. Smooth and compact PPy films could be generated under long polymerization time and low current density. Multi-potential steps polymerization decreases the occurrence of peroxidation, which improves the conductivity of PPy films. The parameters for multi-potential steps polymerization have been optimized. | LI BaoSong QI HongXu ZHAI WenTao ZHANG YaLing ZHANG Xiang LI ShuXi WEI Yan | 2011 | Science China(Technological Sciences)2011，54，7： | 1 |
| 3 | Evolution of drug regulations and regulatory innovation for anticancer drugs in China显示文摘Over the past two decades,China has introduced significant changes to drug regulations through regulatory innovations to accelerate drug review and approvals,keeping in line with the rapidly growing scientific innovation in drug research and development(R&D).In this study,we outlined the revolution of drug regulation in China since the establishment of the State Drug Administration in 1998.More particularly,we performed a comprehensive analysis of newly approved anticancer drugs in China from the year 2005 to May 2021,as a powerful illustration of how the revolution has changed the drug R&D landscape.Innovative drug development in China has boomed,benefiting in particular from pro-innovation policies as well as expedited program designations by the authority.We found a significant increase in the number of both imported and domestic new anticancer drugs from 2005 to 2021,with the emergence of drugs with novel mechanisms of action,including immune checkpoint inhibitors and cell therapy products.Drug lag has also been dramatically shortened by more than 70%for imported drugs in years 2016-2020 compared to years 2006-2010.Furthermore,we provide an insight into the potential approaches to further optimize the science-based and clinical value-based regulatory and R&D drug ecosystem in China.This review provides evidence of significant impacts of regulations and policies on drug R&D and suggests that the constantly adapting regulatory ecosystem will speed up drug development in China and worldwide. | Yang Liu Ning Zhang Cuicui Xie Yale Jiang Yunhe Qin Liyun Zhou Yi Fan Lianjie Ren Chen Yin Huan Yang Wei Xie Qing Zhai Guanqiao Li Hongzhuan Chen Xiaoyuan Chen | 2022 | Acta Pharmaceutica Sinica B2022，12，12： | 1 |
