| 1 | Standard pancreatoduodenectomy versus extended pancreatoduodenectomy with modified retroperitoneal nerve resection in patients with pancreatic head cancer:a multicenter randomized controlled trial显示文摘Background:The extent of pancreatoduodenectomy for pancreatic head cancer remains controversial,and more high-level clinical evidence is needed.This study aimed to evaluate the outcome of extended pancreatoduodenectomy(EPD)with retroperitoneal nerve resection in pancreatic head cancer.Methods:This multicenter randomized trial was performed at 6 Chinese highvolume hospitals that enrolled patients between October 3,2012,and September 21,2017.Four hundred patients with stage I or II pancreatic head cancer and without specific pancreatic cancer treatments(preoperative chemotherapy or chemoradiation)within three months were randomly assigned to undergo standard pancreatoduodenectomy(SPD)or EPD,with the latter followed by dissection of additional lymph nodes(LNs),nerves and soft tissues 270◦on the right side surrounding the superior mesenteric artery and celiac axis.The primary endpoint was overall survival(OS)by intention-to-treat(ITT).The secondary endpoints were disease-free survival(DFS),mortality,morbidity,and postoperative pain intensity.Results:TheR1 ratewas slightly lower with EPD(8.46%)thanwith SPD(12.56%).The morbidity and mortality rates were similar between the two groups.The median OS was similar in the EPD and SPD groups by ITT in the whole study cohort(23.0 vs.20.2 months,P=0.100),while the median DFS was superior in the EPD group(16.1 vs.13.2 months,P=0.031).Patients with preoperative CA19–9<200.0 U/mL had significantly improved OS and DFS with EPD(EPD vs.SPD,30.8 vs.20.9 months,P=0.009;23.4 vs.13.5 months,P<0.001).The EPD group exhibited significantly lower locoregional(16.48%vs.35.20%,P<0.001)andmesenteric LNrecurrence rates(3.98%vs.10.06%,P=0.022).The EPD group exhibited less back pain 6 months postoperation than the SPD group.Conclusions:EPD for pancreatic head cancer did not significantly improve OS,but patients with EPD treatment had significantly improved DFS.In the subgroup analysis,improvements in bothOS and DFS in the EPD armwere observed in patients with preoperative CA19–9<200.0 U/mL.EPD could be used as an effective surgical procedure for patients with pancreatic head cancer,especially those with preoperative CA19–9<200.0 U/mL. | Qing Lin Shangyou Zheng Xianjun Yu Meifu Chen Yu Zhou Quanbo Zhou Chonghui Hu Jing Gu Zhongdong Xu LinWang Yimin Liu Qingyu Liu MinWang Guolin Li He Cheng Dongkai Zhou Guodong Liu Zhiqiang Fu Yu Long Yixiong Li Weilin Wang Renyi Qin Zhihua Li Rufu Chen | 2023 | Cancer Communications2023，43，2： | 3 |
| 2 | Auction mechanism design of the Chinese national carbon market for carbon neutralization显示文摘The carbon market auction mechanism is an important policy tool for carbon pricing and a key mechanism that supports carbon emission neutralization,especially for China.A few systematic studies exist on China’s carbon market auction mechanism.This article focuses on the five auction mechanisms in Chinese pilot emission trading schemes(ETS),reviews the structures and bidding situation of the five-pilot auction mechanism,extracts the similarities,and analyzes their different features,such as auction mode,bidding scale,participants,pricing mode,auction frequency,and so on.This study conducts an in-depth analysis of the carbon allowance auction mechanism in the Guangdong pilot ETS of China,including its development and the evolution of the key elements,its operational effects,and related disputes.Finally,this study puts forward the trend forecast and suggestions for the Chinese allowance auction mechanism,such as the time window of launching national allowance auctions,the most likely auction mode,carbon pricing,and bidding revenue management.Carbon pricing by auction is the most powerful policy tool for addressing carbon emissions reduction and implementing the Glasgow Climate Pact. | Wenjun Wang Xujie Zhao Qiaqia Zhang Chonghui Fu Pengcheng Xie | 2022 | Chinese Journal of Population,Resources and Environment2022，20，2： | 0 |
| 3 | Development of a novel virus-like particle-based vaccine for preventing tick-borne encephalitis virus infection显示文摘Tick-borne encephalitis virus(TBEV)is an important tick-borne pathogen that poses as a serious public health concern.The coverage and immunogenicity of the currently available vaccines against TBEV are relatively low;therefore,it is crucial to develop novel and effective vaccines against TBEV.The present study describes a novel strategy for the assembly of virus-like particles(VLPs)by co-expressing the structural(core/prM/E)and non-structural(NS2B/NS3Pro)proteins of TBEV.The efficacy of the VLPs was subsequently evaluated in C57BL/6 mice,and the resultant IgG serum could neutralize both Far-Eastern and European subtypes of TBEV.These findings indicated that the VLP-based vaccine elicited the production of cross-subtype reactive antibodies.The VLPs provided protection to mice lacking the type I interferon receptor(IFNAR^(-/-))against lethal TBEV challenge,with undetectable viral load in brain and intestinal tissues.Furthermore,the group that received the VLP vaccine did not exhibit significant pathological changes and the inflammatory factors were significantly suppressed compared to the control group.Immunization with the VLP vaccine induced the production of multiple-cytokine-producing antiviral CD4+T cells in vivo,including TNF-α^(+),IL-2^(+),and IFN-γ^(+)T cells.Altogether,the findings suggest that noninfectious VLPs can serve as a potentially safe and effective vaccine candidate against diverse subtypes of TBEV. | Jielin Tang Muqing Fu Chonghui Xu Bao Xue Anqi Zhou Sijie Chen He Zhao Yuan Zhou Jizheng Chen Qi Yang Xinwen Chen | 2023 | Virologica Sinica2023，38，5： | 0 |
