    Abstract Covering: 2010 to 2021Natural nematicidal metabolites are important sources of nematode control. This review covers the isolation and structural determination of nematicidal metabolites from 2010 to 2021. We summarise chemical structures, bioactivity, metabolic regulation and biosynthesis of potential nematocides, and structure-activity relationship and application potentiality of natural metabolites in plant parasitic nematodes' biocontrol. In doing so, we aim to provide a comprehensive overview of the potential roles that natural metabolites can play in anti-nematode strategies.

    Abstract Tumors defective in DNA mismatch repair (dMMR) exhibit microsatellite instability (MSI). Currently, patients with dMMR tumors are benefitted from anti-PD-1/PDL1-based immune checkpoint inhibitor (ICI) therapy. Over the past several years, great progress has been made in understanding the mechanisms by which dMMR tumors respond to ICI, including the identification of mutator phenotype-generated neoantigens, cytosolic DNA-mediated activation of the cGAS-STING pathway, type-I interferon signaling and high tumor-infiltration of lymphocytes in dMMR tumors. Although ICI therapy shows great clinical benefits, ∼50% of dMMR tumors are eventually not responsive. Here we review the discovery, development and molecular basis of dMMR-mediated immunotherapy, as well as tumor resistant problems and potential therapeutic interventions to overcome the resistance.

    Abstract Objective: To systematically evaluate the efficacy and safety of platelet-rich plasma in patients with knee osteoarthritis. Methods: The Pubmed, Cochrane Library, Embase,and Medline were investigated from 2005 through May 2020.All randomized double-blind controlled trials were included the effect of PRP injections for KOA. Literature screening and data extraction were carried out independently by two researchers, and the quality of the included randomized controlled trials was evaluated one by one according to the Cochrane collaboration standards. Meta-statistical analysis was performed for the studies that met the inclusion standards using RevMan5.3. Results: In this study,(1)Seven studies met the eligibility criteria, including 250 patients in the experiment (PRP)group and 230patients in the control(no PRP)group.(2)Metaanalysis results showed that the WOMAC Scores was differed significantly between the PRP and no PRP groups at the 6 months follow-up(MD=9.63,95%CI:3.29 to 15.96,P=0.003),and 12 months follow-up(MD=3.85,95%CI:2.66 to 5.04,P<0.00001)(P<0.05).In a comparison of KOOS function scores at the 6 months follow-up, PRP improved knee function scores more than no PRP(MD=8.63,95%CI:0.85 to 16.42,P=0.03) (P<0.05).PRP injections reduced pain more effectively than no PRP injections in patients with KOA at 3,6 months of follow-up, and the VAS pain score showed a significant difference(SMD=0.88,95%CI:0.13 to 1.62,P=0.02) (SMD=0.85,95%CI:0.11 to 1.59,P=0.002)(P<0.05). However, Adverse Events (AEs) were all not significantly different(RR=0.96,95%CI:0.65 to 1.40,P=0.82)(P>0.05).(3)Results showed that PRP has significant advantages in pain relief and functional improvement. Conclusions: In improving knee function and relieving pain, PRP showed superiority to other non-surgical treatments in long-term follow-up from well-designed double-blind trials. Due to the limited quality and data, more high-quality multi-center studies are required.

    Abstract Reconstruction of network is to infer the relationship among nodes using observation data, which is helpful to reveal properties and functions of complex systems. In view of the low reconstruction accuracy based on small data and the subjectivity of threshold to infer adjacency matrix, the paper proposes two models: the quadratic compressive sensing (QCS) and integer compressive sensing (ICS). Then a combined method (CCS) is given based on QCS and ICS, which can be used on binary-state and multi-state dynamics. It is found that CCS is usually a superior method comparing with compressive sensing, LASSO on several networks with different structures and scales. And it can infer larger node correctly than the other two methods. The paper is conducive to reveal the hidden relationship with small data so that to understand, predicate and control a vast intricate system.

    Abstract The development of digital economy is a strategic choice to grasp the revolution of new science and technology and the new opportunities of industrial reform. The development of digital economy depends on the good support of policy and theoretical system. Therefore, the quantitative evaluation of policy texts provides the basis of decision-making and the suggestions of path optimization for the formulation and improvement of digital economy policy of China. By selecting the text of digital economy policy issued by China government, the paper constructs a quantitative evaluation model of digital economy policy using the methods of content analysis and text mining. The empirical research results show that the overall design evaluation of the selected policy is relatively reasonable. Six policies were evaluated as excellent and two as acceptable. In view of the problems such as lack of predictive policy in the policy type, lack of specific policy in the policy timeliness, imbalance in the use of policy guarantee, and lack of comprehensive coverage in the policy objectives, the paper puts forward corresponding countermeasures and suggestions.
