This study reports the first death caused by a novel avian influenza A (H7N9) virus in Zhejiang Province, China. The patient had chronic hepatitis B and history of exposure to poultry. The patient initially complained of diarrhea and influenza-like symptoms on March 7 and 14 respectively. The disease progressed to severe pneumonia, sustained hypoxia, and coagulation abnormalities. The patient died on March 27 because of respiratory failure, multiple organ failure, and disseminated intravascular coagulation without oseltamivir treatment. This H7N9 virus from Zhejiang is highly similar to isolates obtained from Shanghai, Jiangsu, Anhui, etc. Analysis of hemagglutinin, neuramidinase, and matrix genes indicated that the isolates share the same avian origin, have low virulence, and are sensitive to oseltamivir, but are resistant to adamantine. Only the isolate that caused the fatality exhibited substitution of Q226I in the HA gene, which indicates a potentially enhanced human affinity. The secondary transmission rate was 1.6% (2/125). Only two health workers presented with influenza-like symptoms, and they subsequently tested negative for H7N9 RNA. In conclusion, underlying disease, late diagnosis, and untimely antiviral treatment are possible high-risk factors for infections and death caused by the low-pathogenicity avian influenza A (H7N9). Person-to-person transmission of the H7N9 virus was not detected among close contacts, but such transmission should be investigated in the future. Expanding and enhancing surveillance will help in the early discovery and diagnosis of suspected cases, which will reduce the number of severe cases and deaths.

Several universal influenza virus vaccine candidates based on eliciting antibodies against the hemagglutinin stalk domain are in development. Typically, these vaccines induce responses that target group 1 or group 2 hemagglutinins with little to no cross-group reactivity and protection. Similarly, the majority of human anti-stalk monoclonal antibodies that have been isolated are directed against group 1 or group 2 hemagglutinins with very few that bind to hemagglutinins of both groups. Here we review what is known about the human humoral immune response to vaccination and infection with H7 subtype influenza viruses on a polyclonal and monoclonal level. It seems that unlike vaccination with H5 hemagglutinin, which induces antibody responses mostly restricted to the group 1 stalk domain, H7 exposure induces both group 2 and cross-group antibody responses. A better understanding of this phenomenon and the underlying mechanisms might help to develop future universal influenza virus vaccine candidates.

2013年,H7N9病毒在哺乳动物宿主之间迅速传播,并具有人与人之间传播的风险。间充质干细胞(mesenchymal stem cell, MSC)移植在病毒性肺炎的治疗中有广阔的前景,并于2013年作为应急性治疗方法来治疗H7N9感染的ARDS。根据自愿和知情同意的原则,17例H7N9感染的ARDS患者移植同种异体经血来源的MSC作为治疗组,44例H7N9感染的ARDS患者作为对照组。总体而言,该研究结果表明MSC移植显著提高了H7N9感染的ARDS的存活率,并为开展临床前和临床应用MSC治疗H7N9感染的ARDS的研究提供了理论基础。由于H7N9和2019新型冠状病毒性肺炎(coronavirus disease 2019, COVID-19)临床表现相似(如ARDS和呼吸衰竭),并继发多器官功能障碍,因此基于MSC的疗法可能为COVID

The aim of the paper is to analyze the nonlinear dynamics of robotic arms with elastic links and joints. The main contribution of the paper is the comparative assessment of assumed modes and finite element methods as more convenient approaches for computing the nonlinear dynamic of robotic systems. Numerical simulations comprising both methods are carried out and results are discussed. Hence, advantages and disadvantages of each method are illustrated. Then, adding the joint flexibility to the system is dealt with and the obtained model is demonstrated. Finally, a brief description of the optimal motion generation is presented and the simulation is carried out to investigate the role of robot dynamic modeling in the control of robots.

B7 homolog 3 (B7-H3) has attracted much attention in glioblastoma (GBM) radioimmunotherapy (RIT) due to its abnormally high expression on tumor cells. In this study, we report that two specific humanized anti-human B7-H3 antibodies (hu4G4 and hu4H12) derived from mouse anti-human B7-H3 antibodies that were generated by computer-aided design and exclusively recognize membrane expression of B7-H3 by human glioma cells. Hu4G4 and hu4H12 were radiolabeled with 89Zr for RIT antibody screening. Micro-positron emission tomography (PET) imaging, biodistribution and pharmacokinetic (PK) analyses of 89Zr-labeled antibodies were performed in U87-xenografted models. 125I labelling of the antibodies for single-photon emission computed tomography (SPECT) imaging was also used to investigate the biological behavior of the antibodies in vivo. Furthermore, the pharmacodynamic (PD) of the 131Ilabeled antibodies were evaluated in U87-xenografted mice and GL261 Red-FLuc-B7-H3 in situ glioma tumor models. Micro-PET imaging and biodistribution analysis with a gamma counter showed that 89Zr-deferoxamine (DFO)-hu4G4 had higher tumor targeting performance with lower liver uptake than 89Zr-DFO (hu4H12, immunoglobulin G (IgG)). The biodistribution results of 125I-SPECT imaging were similar to those of 89Zr-PET imaging, though the biodistribution in long bone joints and the thyroid varied. The PD analysis results indicated that 131I-hu4G4 had an excellent therapeutic effect and high safety with no apparent toxicity. Interestingly, 131I-hu4G4 improved the tumor vasculature in tissues with higher expression of collagen type IV and platelet-derived growth factor receptor b (PDGFR-b) compared with control treatment, as determined by immunofluorescence (IF), which contributed to inhibiting tumor growth. Taken together, our data indicate that hu4G4 exhibits good tumor targeting and specificity, achieves low nonspecific concentrations in normal tissues, and has acceptable PK characteristics. 131I-hu4G4 also exerts effective antitumor effects with an ideal safety profile. Therefore, we expect hu4G4 to be an excellent antibody for the development of GBM RIT.
