The overall strategy of the "four major sectors", the regional major strategies and the major functional oriented zoning strategy have strongly supported the regional coordinated development in China. However, it also brings the risk of exacerbating the imbalance and incoordination of regional development due to strategic differences and segmentation. Based on an analysis of the trends in regional coordinated development in China, this study puts forward the layout of China's comprehensive function regions, which divides the mainland of China into 10 regions: the Beijing-Tianjin-Hebei region, the Yangtze River Delta region, the middle reaches of Yangtze River basin, the upper reaches of Yangtze River basin, the Southern coastal region, the lower reaches of Yellow River basin, the Ji shaped bay area of the Yellow River basin, the Northeast region, the arid region of Northwest China, and the Qinghai-Tibet Plateau, with the functional orientation and recent key tasks of different regions addressed. The layout of comprehensive function regions highlights the full coverage of territorial space, and the guidance of core area and major strategies. Moreover, it is conducive to promoting the convergence and integration of the overall strategy of the "four major sectors", the regional major strategies, and the major functional oriented zoning strategy.

Since the middle of the 20th century, peace and development have been the themes of the world. The global economy has been growing at an unprecedented speed, breadth and depth, and the economic center of gravity has shifted from west to east, profoundly changing the pattern of global economic geography. In the future, a new round of scientific and technological revolution and industrial transformation, as well as changes in the global governance system and order, will further accelerate this change. In the face of changes unseen in a century, this paper summarized the overall evolution characteristics and patterns of global economic geography pat‐tern since the middle of the 20th century. This paper concluded that the pattern of global eco‐ nomic geography is characterized by a gradual slowdown in growth, shift of the economic center of gravity to the east, decline in the degree of polarization, and trade as the main driver of development. Global economic geography has formed an evolutionary model of regional economic integration development, spatial spillover of regional economic development, and industrial chain linkage. In the future, the center of gravity of the global economy will continue to shift eastward, and the evolution of the global economic landscape and the transformation of the inter‐ national order will accelerate. Countries should work together to address global issues and pro‐ mote the economic and social development of mankind. [ABSTRACT FROM AUTHOR]

Quarantine and isolation are effective means to prevent transmission of COVID-19, but the problems arised during the period of quarantine and isolation are worth pondering. This article first streamlines five types of problems during the recent period of quarantine and isolation. Based on a brief review of related research on domestic and international literature, the article argues that it will be a suitable approach to carry out research from the perspective of spatial organization combined with the concept of systems theory. Then, it explores the reasons of the aforementioned problems from the objective laws of spatial organization and systems theory. It points out that the lack of systematical consideration of quarantine and isolation decisions in theory and the absence of preparations for switching from normal to abnormal status in practice are the fundamental reasons. Finally, three policy suggestions have been proposed from the perspectives of the optimization of spatial organization system, the enhancement of infrastructure and capabilities, and the backup mechanism and drills.

Objective To investigate the correlation between IL-34, CTRP13 and unstable angina (UA) with type 2 diabetes mellitus (T2DM). Methods A total of 150 patients admitted to the Affiliated Hospital of Chengde Medical University were collected and divided into 3 groups according to the clinical data and coronary angiography results: UA+ T2DM group (n=50), UA group (n=50) and T2DM group (n=50)，and healthy people who had physical examination at the same period were selected as the control group (n=50). The serum levels of IL-34 and CTRP13 were detected by ELISA. The differences of clinical indexes were compared between the four groups. The correlation between IL-34, CTRP13 and WC, FPG, hs-CRP, Gensini score in the UA+T2DM group were analyzed. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic values of IL-34 and CTRP13 for UA with T2DM. Results The serum levels of IL-34 increased in the control group, T2DM group, UA group and UA+T2DM group in turn (all P＜0.05). The serum levels of CTRP13 decreased in the control group, UA group, T2DM group and UA+T2DM group in turn (all P＜0.05). The Gensini score was significantly higher in UA+T2DM group than that of UA group (P＜0.05). Correlation analysis showed that serum IL-34 level was positively correlated with WC, FPG, hs-CRP and Gensini score in UA+T2DM group, but negatively correlated with CTRP13 (all P＜0.05). The serum level of CTRP13 was negatively correlated with hs-CRP, FPG and Gensini score (all P＜0.05). The ROC curve showed that the areas under the curves of IL-34, CTRP13 and joint indicators were 0.784 (0.716-0.852), 0.820 (0.759-0.882) and 0.847 (0.787-0.906) in the diagnosis of UA with T2DM. Conclusion The serum level of IL-34 is higher and the serum level of CTRP13 is lower in UA patients with T2DM. The serum levels of IL-34 and CTRP13 have predictive values for the diagnosis and the severity of coronary artery disease in UA with T2DM. [ABSTRACT FROM AUTHOR]

Objective To investigate the clinical application of Carba NP test in detecting carbapenem-resistant enterobacteriaceae. Methods Routine method was adopted to identify the 51 strains from clinical isolates and K-B test was conducted to screen out the carbapenem-resistant enterobacteriaceae and detect antimicrobial susceptibility. E-test was used to detect the minimum inhibitory concentration (MIC) of carbapenems. Modified Hodge test (MHT) and Carba NPⅠ test were used to screen out the phenotypes of carbapenemase, respectively. Then Carba NPⅡ test was used to classify carbapenemase which were positive in Carba NP I test. E-test was used for the detection of metalloenzymes. Polymerase chain reaction (PCR) was used for the detection of resistance genes. Results Totally 41 strains were positive in Carba NP 1 test and classified as B-class by Carba NPⅡ test. They were positive in metalloenzyme by E-test and carried NDM-1 gene by PCR. Conclusion Carba NP test can be used conveniently, has high consistency with PCR method, and the result is easy to determine. Therefore, it can be used as a routine laboratory method.

Objective To investigate the value of growth differentiation factor 15 (GDF-15), soluble ST2 (sST2) and brain natriuretic peptide (BNP) in evaluating the cardiac function of patients with chronic heart failure ( HF). Methods A total of 70 in patients with chronic heart failure were divided into class H ( n = 24) and V ( n = 46) according to the NYHA class. Another 31 patients with hypertension or cardiac arrhythmias were recruited as the control group. Heart function, GDF-15, sST2 and BNP were detected by echocardiography , ELISA method and BNP bedside detector，respectively. Results Compared with control group，the levels of GDF-15，sST2，BNP，left ventricular end-diastolic dimension (LVEDD) and left ventricular mass index (LVMI) were higher, and the levels of left ventricular ejection fraction ( LVEF) and relative wall thickness (RWT) were lower in the HF group, and the differences were statistically significant ( all P <0.01). Compared with NYHA H HF patients，the levels of GDF-15，sST2，BNP，LVEDD and LVMI were higher，the levels of LVEF and RWT were lower in NYHA V HF patients, and the differences were statistically significant (all P <0.05). Spearman correlation analysis showed that ssT2，GDF-15 and BNP were positively correlated with LVMI and NY- HA class ( r = 0. 351, 0. 236, 0. 449 ； 0. 339, 0. 305 , 0. 579; all P < 0. 05 ), while were negatively correlated with RWT and LVEF (r= -0.380, -0.255, -0.496； -0.257, -0.298, -0.409； all P<0.05). GDF-15 and sST2 were posi­tively correlated with BNP (r = Q. 289 , 0. 300； all P < 0. 05 ). ROC curve analysis showed that the area under curve of NYHA H and NYHA ^ with BNP , GDF-15 and sST were 0. 852 , 0.678 and 0. 706 , respectively (all P <0. 05). Conclusion The levels of GDF-15 , sST and BNP are closely related with cardiac functional status in patients with chronic HF , and they all may reflect the severity of the patients' condition, but BNP has a higher sensitivity and specificity in the evaluation of cardiac function in HF patients.

By using the properties of Nega-Hadamard transform, this paper studied the relationship between bent function and its dual in the Nega-Hadamard transform. It showed that if bent function was a negabent, then its dual was again negabent. Also, it obtained the property of the Nega-Hadamard transform of Boolean function f in some affine subspace. At last, it provided the relationship between the Nega-Hadamard transforms of the derivatives of f and the dyadic shifts. [ABSTRACT FROM AUTHOR]
