Modern physical geography in China grew from Chinese traditional geography and has been profoundly influenced by the geographical disciplines of Euro-America and Russia. Since the 1950 s, integrated studies of physical geography in China have made remarkable progress in the fields of comprehensive physical geographical regionalization, land studies, landscape ecology, and land surface geographical processes. During the past few decades, under the background of global change and rapid socio-economic transformation, a series of environmental and resources problems have boomed in China. To solve these problems and promote the development of integrated studies of physical geography, the following issues were proposed as research priorities:(1) coupling of land surface patterns and processes;(2) integrated research on regional responses and adaptation to global change;(3) analysis of human dimensions of the earth system;(4) ecosystem service research from a geographical perspective;(5) integration of multi-source data and model development;(6) integrated studies on unique geographical units; and(7) important global issues and relevant international programs. 展开更多

Global change research and sustainable development need to be addressed at larger scales in the light of small scale process studies. Much remains to be done before the small scale, process level understanding of ecosystem responses to global change can be reliably translated to larger scales. The paper reviews the status of scaling issues and tries to find how to extrapolate our observations and our findings at site scale up to regional scale and provide ecological information and interpretations at the regional scale. An integrated approach to scaling-up from site to region is proposed combining hierarchical theory, landscape ecology, remote sensing, geographical information system (GIS) with process/mechanistic modeling. Remote sensing and GIS will play key roles in spatial analysis, integration as well as cross scale modeling. 展开更多

Background:Oral administration of indigo naturalis(IN)is used as a complementary and alternative medicine(CAM)regimen for the treatment of myelodysplastic syndromes(MDS).However,its mechanism of action has not been fully elucidated and needs to be further explored.Methods:By searching the traditional Chinese medicine system and analyzing platforms(TCMSP),bioinformatics analysis tool for the molecular mechanism of traditional Chinese medicine(BATMAN-TCM),and Swiss Target Prediction network database,the main active components and potential targets of IN were obtained.Based on this,a component-target network was established by Cytoscape 3.6.1 software.Differentially expressed genes(DGEs)in MDS were obtained from three GEO(Gene Expression Omnibus)gene chips.Then,the protein-protein interaction(PPI)network of DGEs was constructed and analyzed by STRING database and Cytoscape 3.6.1 software.In addition,Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)biological enrichment analysis were carried out using REVIGO and KEGG Orthology Based Annotation System(KOBAS)on DGEs,respectively.Identification of IN-MDS compound targets was performed by matching potential targets of active components with disease-related targets.The results of KEGG pathway enrichment analysis were combined with compound targets to screen key targets.In the end,molecular docking was performed by SYBYL-X2.1 to verify the key targets.Results:Nine active components of IN and 439 potential targets of IN were identified by analyzing TCMSP,BATMAN-TCM,and Swiss Target Prediction network databases.Three MDS disease-related gene microarray chips were obtained from the GEO databases:GSE4619,GSE19429,and GSE58831.Through this analysis,87 DEGs were finally obtained using the Venn diagram.A PPI network of DEGs was then constructed,in which 18 genes were upregulated and 69 genes were downregulated.After the GO enrichment results were de-redundant,the representative GO terms were obtained by using REVIGO semantic similarity measuremen.The KEGG biological pathway analysis using the KOBAS indicated that the Hippo signaling pathway is important in MDS.The Hippo signaling pathway involves four genes:AREG,LEF1,SMAD7,and TCF4.By matching and mapping DEGs with potential targets,six IN-MDS compound targets were obtained:PDE4B,PLAUR,ELANE,NR3C1,AREG,and LEF1.We found that AREG and LEF1 are consistent with the genes involved in the Hippo signaling pathway.Through molecular docking simulation,we found that the indican binds best to AREG and LEF1.Conclusion:Based on the integrated pharmacology model,the material basis of the efficacy and biological molecular mechanism of IN in the treatment of MDS was systematically studied,which provided a novel indication of the CAM regimen for the improvement of MDS management. 展开更多

Objective: To evaluate the efficacy of integrative Chinese and western medicine (ICWM) in treating severe acute respiratory syndrome (SARS) patients. Methods: Through parallel control design, 49 SARS patients were observed. Used as control, there were in the western medicine (WM) group 29 patients, who were treated with Ribavirin, Levofloxacin, Thymopentin, Azithromycin, methylprednisolone, etc. , on the basis of 'Recommended Protocol for Infectious Atypical Pneumonia' (abbreviated as 'Recommended Protocol') issueed by Ministry of Health. As the treated group, there were in the ICWM 20 cases. The protocol for treatment of SARS in 'Special Science and Technological Action to Prevent and Treat SARS' (abbreviated as 'Special S-T Action'), issued by Ministry of Science and Technology, together with the same WM as those for the control group. Results: (1) Time from the disease onset to the symptom improvement were 5.10±2. 83 days and 7. 62±2. 27 days in ICWM and WM group respectively, P<0.05; (2) As to corticosteroid (CS) amount and days before reducing dosage, 2 groups showed no significant difference, P>0. 05;(3) There was no significant difference in the time from disease onset to the body temperature normalization and the total amount of CS and the duration of using CS before reducing it to 80 mg between the ICWM group and the WM group; (4) The days and amounts for use CS after reducing between the ICWM group and the WM group were significantly different (P<0. 05). Conclusion: There were obvious advantages in ICWM to treat SARS, compared with that of WM alone, especially in improving the clinical symptoms, promoting the recovery of immune function, promoting the absorption of pulmonary inflammation and reducing the dosage and duration of CS treatment. 展开更多

Background: A Randomized Controlled Trial (RCT) has been elaborated where goal directed fluid and hemodynamic therapy (GDFHT) will be realized with trans-thoracic echocardiographic aortic blood flow peak velocity variation (ΔVpeak) and distance minute (DM) to guide fluid therapy and hemodynamics in high risk pediatric surgical patients. This RCT will clarify the impact of GDFHT with ΔVpeak and DM on postoperative outcome in terms of morbidity, length of stay in the intensive care unit (LOSICU), length of mechanical ventilation (LMV) and length of hospital stay (LOS) in children. To determine values of ΔVpeak, DM and VTI predictive of these postoperative outcomes, an observational pilot study will be realized. This pilot study is described here. The primary objective of this study is to determine values of ΔVpeak, DM and ITV predictive of postoperative outcome in children in terms of morbidity. The secondary objectives are to determine values of ΔVpeak, DM and ITV predictive of LOSICU, LMV, LOS, intraoperative, postoperative fluid administration and vasoactive-inotropic therapy. Methods: 500 - 1000 children aged less than 18 years will be included prospectively. Statistic analysis will be realized with XLSTAT 2019.4.2 software or plus. Results and Conclusions: This trial protocol will determine values of ΔVpeak, DM and ITV with echocardiography predictive of postoperative outcome in children. 展开更多

This paper collects and synthesizes the technical requirements, implementation, and validation methods for quasi-steady agent-based simulations of interconnectionscale models with particular attention to the integration of renewable generation and controllable loads. Approaches for modeling aggregated controllable loads are presented and placed in the same control and economic modeling framework as generation resources for interconnection planning studies. Model performance is examined with system parameters that are typical for an interconnection approximately the size of the Western Electricity Coordinating Council(WECC) and a control area about 1/100 the size of the system. These results are used to demonstrate and validate the methods presented. 展开更多

Background: In the past we have shown the preservation and improvement of cognitive tasks in depressed and demented patients after 24 and 36 months of combined pharmacological and non-pharmacological treatment. Here we present the results of our ongoing, naturalistic study, in the same outpatient setting, at 60 month follow up. Materials and Methods: The study group consisted of 156 medically ill, physically disabled patients with mild to moderate dementia and depression. Patients were treated with antidepressants, cholinesterase inhibitors, and NMDA antagonists, along with their regular medication regimen. Non-pharmacological intervention was centered on a home-based program of physical and cognitive exercises paired with vitamins and supplements (multivitamins, vitamin E, L-methylfolate, alphalipoic acid, acetyl-L-carnitine, omega-3, and coenzyme Q-10) and diet modification. Cognitive assessments were performed yearly. Results: After 60 months of treatment, performance of all tasks remained at or above baseline. The MMSE, Cognistat-Attention, Cognistat-Judgment, and RFFT-Total Unique Designs demonstrated significant improvement. Conclusion: Our results, for the first time, demonstrate arrest in cognitive decline in demented/depressed patients with multiple medical co-morbidities for 60 months. Future investigations addressing the application of a combined, integrative treatment model are warranted. 展开更多

Parametric study is carried out in the present article to investigate the unsteady performance of solar energy gain and heat retention of two different integrated-collector-storage systems. The systems are the conventional rectangular-shaped storage tank and the modified tank shaped as rectangular cuboid with one semi -circular top. The two systems have the same absorber surface area and volume for water. The heat and fluid flow is assumed to be unsteady, two-dimensional, laminar and incompressible. The performances of the two systems are evaluated based on the maximum temperature in the system during daytime heating period and nighttime cooling period. For comprehensive study, 24 hours simulations for 3 cases with different wall boundary condition impose on the absorber plate are investigated. The simulation results show that the modified system has better heat retain than the conventional system. Periodic variations of both systems are investigated, and it is found that both systems show consistent results on different days. The modified system is able to store most of the thermal energy in the semi-circular top region with higher temperature than that of the conventional system. 展开更多

The network integration provides users with a new network with long connection time and a high data rate when needed, but it also brings the defects of all the networks that integrate together into the integrated network. This will cause all kinds of existing and some new security problems in the operation of the integrated network. A complete protection based on recovery is proposed in the paper. It uses the public-key algorithm to authorize and private-key algorithm to encrypt the communicating data. This solution can provide the system with reliable security, and avoid Denial of Service (DoS) of the user. This solution has been proposed lately, and we should further identify the correct action of all the layers and figure out how to react when a legal node is framed by multiple malicious nodes. 展开更多
