| 2 | Chinese Trauma Surgeon Association for management guidelines of vacuum sealing drainage application in abdominal surgeries-Update and systematic review显示文摘Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chin ese Trauma Surge on Associati on orga nized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries.Eleven questions regarding the use of VSD in abdominal surgeries were addressed:(1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions?(2) Can VSD be preventively used for a high-risk abdominal incision w让h primary suture?(3) Can VSD be used in severely contaminated/infected abdominal surgical sites?(4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome?(5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage?(6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula?(7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess?(8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects?(9) Does VSD in crease the risk of bleeding?(10) Does VSD increase the risk of intestinal wail injury?(11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure. | Yang Li Pei-Yuan Li Shi-Jing Sun Yuan-Zhang Yao Zhan-Fei Li Tao Liu Fan Yang Lian-Yang Zhang Xiang-Jun Bai Jing-Shan Huo Wu-Bing He Jun Ouyang Lei Peng Ping Hu Yan-An Zhu Ping Jin Qi-Feng Shao Yan-Feng Wang Rui-Wu Dai Pei-Yang Hu Hai-Ming Chen Ge-Fei Wang Yong-Gao Wang Hong-Xu Jin Chang-Ju Zhu Qi-Yong Zhang Biao Shao Xi-Guang Sang Chang-Lin Yin | 2019 | Chinese Journal of Traumatology2019，22，1： | 26 |

| 5 | LHD1,an Allele of DTH8/Ghd8,Controls Late Heading Date in Common Wild Rice (Oryza rufipogon)显示文摘Flowering at suitable time is very important for plants to adapt to complicated environments and produce their seeds successfully for reproduction.In rice (Oryza rufipogon Griff.) photoperiod regulation is one of the important factors for controlling heading date.Common wild rice,the ancestor of cultivated rice,exhibits a late heading date and a more sensitive photoperiodic response than cultivated rice.Here,through map-based cloning,we identified a major quantitative trait loci (QTL) LHD1 (Late Heading Date 1),an allele of DTH8/Ghd8,which controls the late heading date of wild rice and encodes a putative HAP3/NF-YB/CBF-A subunit of the CCAAT-box-binding transcription factor.Sequence analysis revealed that several variants in the coding region of LHD1 were correlated with a late heading date,and a further complementary study successfully rescued the phenotype.These results suggest that a functional site for LHD1 could be among those variants present in the coding region.We also found that LHD1 could down-regulate the expression of several floral transition activators such as Ehd1,Hd3a and RFT1 under long-day conditions,but not under short-day conditions.This indicates that LHD1 may delay flowering by repressing the expression of Ehd1,Hd3a and RFT1 under long-day conditions. | Xiaodong Dai Younian Ding Lubin Tan Yongcai Fu Fengxia Liu Zuofeng Zhu Xianyou Sun Xuewen Sun Ping Gu Hongwei Cai Chuanqing Sun | 2012 | Journal of Integrative Plant Biology2012，54，10： | 23 |

| 9 | IL-10 Gene Modified Dendritic Cells Inhibit T Helper Type 1-Mediated Alloimmune Responses and Promote Immunological Tolerance in Diabetes显示文摘Dendritic cells (DCs) have the potency to regulate the outcome of autoimmunity through the modulation of immune responses. The induction of antigen specific tolerance is critical for prevention and treatment of allograft rejection. In the present study,we transfected IL-10 gene into DCs and investigated their effect on inhibition of lymphocyte activity in vitro and induction of immune tolerance on islet allograft in mice. An IDDM C57BL/6 mouse model was induced by streptozotocin. The islet cells isolated from the BALB/c mice were transplanted into the kidney capules of the model mice followed by injection of IL-10 modified DCs (mDCs). The results showed that mDCs could significantly inhibit T lymphocyte proliferation mediated by allotype cells and induce its apoptosis,whereas,unmodified DCs (umDCs) could promote the murine lymphocyte proliferation markedly. The injection of mDCs could prolong the survival of allotype islet transplanted IDDM mice. The average plasma glucose (PG) level in mDCs treated mice returned to normal within 3 days and lasted for about 2 weeks. The rejection response in control mice occurred for 5 days after transplantation. The level of IFN-γ was lower while IL-4 was higher in mDCs treated mice than that in umDCs treated mice,which indicated that Th1/Th2 deviation occurred. Our studies suggest that IL-10 gene modified DCs can induce the immune tolerance to islet graft and prolong survival of the recipients by the inhibiting of T cell proliferation in allotype mice. | Huifen Zhu Wenhong Qiu Ping Lei Wei Zhou Xue Wen Fengrong He Li Li Hong Dai Guanxin Shen Feili Gong | 2008 | Cellular & Molecular Immunology2008，5，1： | 14 |
| 10 | Responses of the Toll-like receptor and melanoma differentiation-associated protein 5 signaling pathways to avian infectious bronchitis virus infection in chicks显示文摘Avian infectious bronchitis virus(IBV) is a Gammacoronavirus in the family Coronaviridae and causes highly contagious respiratory disease in chickens. Innate immunity plays significant roles in host defense against IBV. Here, we explored the interaction between IBV and the host innate immune system. Severe histopathological lesions were observed in the tracheal mucosa at 3–5days post inoculation(dpi) and in the kidney at 8 dpi, with heavy viral loads at 1–11 and 1–28 dpi,respectively. The expression of m RNAs encoding Toll-like receptor(TLR) 3 and TLR7 were upregulated at 3–8 dpi, and that of TIR-domain-containing adapter-inducing interferon(IFN) β(TRIF) was upregulated at 21 dpi in the trachea and kidney. Myeloid differentiation primary response protein 88(My D88) was upregulated in the trachea during early infection. Tumor necrosis factor receptor-associated factor(TRAF) 3 and TRAF6 were upregulated expression in both tissues.Moreover, melanoma differentiation-associated protein 5(MDA5), laboratory of genetics and physiology 2(LGP2), stimulator of IFN genes(STING), and mitochondrial antiviral signaling protein(MAVS), as well as TANK binding kinase 1(TBK1), inhibitor of kappa B kinase(IKK) ?, IKKα, IKKβ,IFN regulatory factor(IRF) 7, nuclear factor of kappa B(NF-κB), IFN-α, IFN-β, various interleukins(ILs), and macrophage inflammatory protein-1β(MIP-1β) were significantly upregulated in the trachea and downregulated in the kidney. These results suggested that the TLR and MDA5 signaling pathways and innate immune cytokine were induced after IBV infection. Additionally,consistent responses to IBV infection were observed during early infection, with differential and complicated responses in the kidney. | Yining He Zhiwen Xie Jinglong Dai Yanjie Cao Jinlian Hou Yansheng Zheng Tianchao Wei Meilan Mo Ping Wei | 2016 | Virologica Sinica2016，31，1： | 14 |
| 11 | Characteristics of Settings and Etiologic Agents of Foodborne Disease Outbreaks—China,2020显示文摘Introduction:Foodborne diseases are a growing public health problem and have caused a large burden of disease in China.This study analyzed epidemiological characteristics of foodborne diseases in China in 2020 to provide a scientific basis for prevention and control measures.Methods:Data were collected from 30 of 31 provincial-level administrative divisions(PLADs)in the mainland of China,excluding Xizang(Tibet)Autonomous Region,via the National Foodborne Disease Outbreaks Surveillance System・The number and proportion of outbreaks,illnesses,hospitalizations,deaths by setting,pathogen-food category pairs and etiology were calculated.Results:In 2020,7,073 foodborne disease outbreaks were reported,resulting in 37,454 illnesses and 143 deaths.Among the identified pathogens,microbial pathogens were the most common confirmed etiology,accounting for 41.7%of illnesses.Poisonous mushrooms caused the largest proportion of outbreaks(58.0%)and deaths(57.6%).For venues where foodborne disease outbreaks occur,household had the highest number of outbreaks(4,140)and deaths(128),and catering service locations caused the largest proportion of illnesses(59.9%).Outbreaks occurring between June and September accounted for 62.8%of total outbreaks.Conclusions:Foodborne disease outbreaks mainly occurred in households・Microbial pathogens remained the top cause of outbreak-associated illnesses.Poisonous mushrooms were ranked the top cause of deaths in private homes in China.The supervision and management of food safety and health education should be strengthened to reduce the burden of foodborne diseases・Publicity should be increased to reduce the incidence of mushroom poisonings in families,and supervision and management of food should be strengthened to reduce microbial contamination. | Hongqiu Li Weiwei Li Yue Dai Yuyan Jiang Junhua Liang Santao Wang Maoqiang Zhuang Zheng Huang Lizi Xu Bo Xue Jikai Liu Haihong Han Sara M.Pires Ping Fu Yunchang Guo | 2021 | China CDC weekly2021，3，42： | 14 |

| 16 | Enhanced therapeutic effects of combined chemotherapeutic drugs and midkine antisense oligonucleotides for hepatocellular carcinoma显示文摘AIM: To evaluate the effect of combined antisense oligonucleotides targeting midkine (MK-AS) and chemotherapeutic drugs [cisplatin(DDP), 5-fluorouracil (5-FU) and adriamycin (ADM)] on inhibition of HepG2 cell proliferation, and to analyze the efficacy of MK-AS used in combined ADM in in situ human hepatocellular carcinoma (HCC) model. METHODS: HepG2 cells were treated with MK-AS and/or chemotherapeutic drugs mediated by Lipofectin, and cell growth activity was determined by MTS assay. An in situ HCC model was used in this experiment. MK- AS, ADM and MK-AS + ADM were given intravenously for 20 d, respectively. The animal body weight and their tumor weight were measured to assess the effect of the combined therapy in vivo. RESULTS: Combined treatment with MK-AS reduced the IC50 of DDP, 5-FU and ADM in HepG2 cells. MK-AS significantly increased the inhibition rate of DDP, 5-FU and ADM. Additionally, synergism (Q 1.15) occurred at a lower concentration of ADM, 5-FU and DDP with combined MK-AS. Combined treatment with MK-AS and ADM resulted in the more growth inhibition on in situ human HCC model compared with treatment with chemotherapeutic drugs alone. CONCLUSION: MK-AS increases the chemosensitivity in HepG2 cells and in situ human HCC model, and thecombination of MK-AS and ADM has a much better in vitro and in vivo synergism. | Li-Cheng Dai Xiang Wang Xing Yao Yong-Liang Lu Jin-Liang Ping Jian-Fang He | 2007 | World Journal of Gastroenterology2007，13，13： | 10 |
| 17 | The historical and current research progress on jujube–a superfruit for the future显示文摘Jujube(Ziziphus jujuba Mill.),or Chinese date,is the most important species of Rhamnaceae,a large cosmopolitan family,and is one of the oldest cultivated fruit trees in the world.It originates from the middle and lower reaches of the Yellow River,the‘mother river’of the Chinese people.It is distributed in at least 48 countries on all continents except Antarctica and is becoming increasingly important,especially in arid and semiarid marginal lands.Based on a systematic analysis of the unique characteristics of jujube,we suggest that it deserves to be recognized as a superfruit.We summarized historical research achievements from the past 3000 years and reviewed recent research advances since 1949 in seven fields,including genome sequencing and application,germplasm resources and systematic taxonomy,breeding and genetics,cultivation theory and techniques,pest control,postharvest physiology and techniques,and nutrition and processing.Based on the challenges facing the jujube industry,we discuss eight research aspects to be focused on in the future. | Mengjun Liu Jiurui Wang Lili Wang Ping Liu Jin Zhao Zhihui Zhao Shengrui Yao Florin Stănică Zhiguo Liu Lixin Wang Changwei Ao Li Dai Xiansong Li Xuan Zhao Chunxiang Jia | 2020 | Horticulture Research2020，7，1： | 10 |

| 20 | NUMERICAL SIMULATIONS OF CAVITATING FLOWS显示文摘A new model, which involves viscous and multi-phase effects, was given to study cavitating flows. A local compressible model was established by introducing a density-pressure function to account for the two-phase flow of water/vapor and the transition from one phase to the other. An algorithm for calculating variable-density N-S equations of cavitating flow problem was put forward. The present method yields reasonable results for both steady and unsteady cavitating flows in 2D and 3D cases. The numerical results of unsteady character of cavitating flows around hydrofoils coincide well with experimental data. It indicates the feasibility to apply this method to a variety of cavitating flows of practical problems. | Ph.D.Candidate:Wu Lei School of Civil Engineering and Mechanics, Shanghai Jiaotong University, Shanghai 200240, China Supervisor:Lu Chuan-jing (Shanghai Jiaotong University) Xue Lei ping (Shanghai Jiaotong University) Members of Dissertation Defense Committee:Dong Shi-tang (China Ship Scientific Research Center),Chairman Dai Shi-qiang (Shanghai University) Zhang Hui-sheng (Fudan University) Miao Guo-ping (Shanghai Jiaotong Universi ty) He You-sheng (Shanghai Jiaotong University)Liu Hua (Shanghai Jiaotong University) Lu Chuang-jing (Shanghai Jiaotong Universi ty) | 2003 | Journal of Hydrodynamics2003，15，4： | 9 |
