[Material basis of kidney Yang deficiency rats before and after salt processing of Dipsacus asper based on spectrum-effect relationship].

This paper aims to study the spectrum-effect relationship between the fingerprints before and after salt processing of Dipsacus asper and the efficacy of warming and tonifying kidney Yang and find the main active components against kidney Yang deficiency before and after salt processing of D. asper, so as to provide the basis for clarifying the effect of salt processing on kidney Yang deficiency. The HPLC fingerprint before and after salt processing of D. asper was established by the HPLC-DAD. 15 common peaks were obtained, and 11 components were identified. The content changes of various components in rat serum were detected, and the difference in efficacy before and after salt processing was compared. The results of pharmacological experiments showed that salt processing of D. asper could enhance the kidney index. At the same dose, there was a significant difference between the raw D. asper and D. asper after salt processing groups. Compared with the model group, the contents of ACTH, cAMP, CORT, E_2, GH, Na~+-K~+-ATPase, T, and T4 in the serum of rats in the administration group increased to a certain extent, and the contents of cGMP and TNF-α decreased to a certain extent. Among them, there were significant differences in the above indexes in the serum of rats in the high-dose group of raw D. asper, middle-dose group of D. asper after salt processing, high-dose group of D. asper after salt processing, and the positive drug group. The overall results showed that D. asper after salt processing was more effective than raw D. asper in preventing kidney yang deficiency. The efficacy of D. asper was evaluated by grey correlation analysis, entropy method, and Pearson correlation analysis, and the components of D. asper after salt processing against kidney yang deficiency were screened out. According to the results of correlation degree ranking, the components with increased ranking before and after salt processing of D. asper were loganin, chlorogenic acid, dipsacoside A, asperosaponin Ⅵ, caffeic acid, and isochlorogenic acid B. It was preliminarily speculated that these compounds may be the potential pharmacodynamic components for the treatment of kidney yang deficiency before and after salt processing of D. asper. The changing components before and after the salt processing of D. asper were determined, which proved that D. asper after salt processing was superior to D. asper in the treatment of kidney yang deficiency. The spectrum-effect relationship between the efficacy of D. asper before and after salt processing and the treatment of kidney yang deficiency was established, which laid a foundation for the subsequent study on the pharmacodynamic components and molecular mechanism of salt processing of D. asper.

Quality evaluation of chicken soup based on entropy weight method and grey correlation degree method.

This study aimed to develop an assessment framework for evaluating the quality of different chicken soup variants. Three types of chicken soup, traditional chicken soup (TCS), concentrated chicken soup (CCS), and blended chicken soup (BCS), were prepared and analyzed for various physicochemical parameters, including gross protein content, crude fat content, pH level, solid content, viscosity, and chromatic aberration value. Sensory evaluation was also conducted to assess overall quality. Correlation analysis helped identify three key evaluation indicators: gross protein content, L* value (lightness), and b* value (chromatic aberration). The weight assigned to gross protein content was the highest using the entropy weight method (EWM). Moreover, the grey correlation degree method was comprehensively applied to evaluate the chicken soup's quality. This analysis identified TCS and CCS as varieties with superior overall quality, showing a positive correlation with sensory evaluation, consistent with the results of nuclear magnetic resonance (NMR) used in this paper. These results provide theoretical support for assessing comprehensive quality and selecting chicken soup varieties.

Evaluation of Steaming and Drying of Black Sesame Seeds for Nine Cycles Using Grey-Correlation Analysis Based on Variation-Coefficient Weight.

This study aimed to improve the steaming process of black sesame seeds. A comprehensive evaluation was conducted using the grey-correlation method based on the variation-coefficient weight to observe the treatments of normal-pressure (NPS) and high-pressure (HPS) steaming (with/without soaking in water) for nine cycles. Their effects on the contents of water, protein, fat, ash, melanin, sesamin, and sesamolin of black sesame seeds, as well as the sensory score of the black sesame pill, were determined. We found that with varied steaming methods and increased steaming cycles, the contents of the nutritional and functional components of black sesame seeds and the sensory score of the black sesame pill differed. The results of the variation-coefficient method showed that water, protein, fat, ash, melanin, sesamin, sesamolin, and sensory score had different effects on the quality of black sesame seeds with weighting factors of 34.4%, 5.3%, 12.5%, 11.3%, 13.9%, 11.3%, 7.8%, and 3.5%, respectively. The results of two-factor analysis of variance without repeated observations indicated that the grey-correlation degree of HPS was the largest among the different steaming treatments, and the following sequence was HPS after soaking in water (SNPS), NPS, and SNPS. There was no significant difference between NPS and SNPS (p < 0.05). Moreover, with increased cycles, the value of the grey-correlation degree increased. The comprehensive score of the procedure repeated nine times was significantly higher than other cycles (p < 0.05). The results of the grey-correlation degree and grade analysis showed that the best steaming process of black sesame seeds was HPS for nine cycles, followed by HPS for eight cycles and NPS after soaking in water (SNPS) for nine cycles. These findings could provide a scientific basis for replacing SNPS with HPS to simplify steaming and realize the parametric steaming of black sesame seeds, and thus, ensure the quality of black-sesame products.

Exploring the Relationship between Ecosystem Services under Different Socio-Economic Driving Degrees.

The large-scale transformation of natural ecosystems to socio-economic development land types under human activities was a primary reason for the decline of regional ecosystem services. It is a key issue for regional ecosystem planning and management to reveal the relationship between ecosystem services of different land use types under different socio-economic driving degrees. However, the current related research was not in-depth. Based on the land use data of Wuhan City in 1980, 1990, 2000, 2010, and 2020, this study classified land use into three categories according to the different degrees of human activities on natural ecosystem development: the land use of a natural ecosystem (LUNE), the land use of a productive ecosystem (LUPE), and the land use of a socio-economic system (LUSE). The InVEST model was used to simulate five ecosystem services (grain yield, water yield, carbon storage, habitat quality, and water purification), and the spatio-temporal distribution and functional transformation of the three land use types were analyzed. Results showed that with the intensified urban expansion in Wuhan, the LUSE types increased to 2.7 times that of the original. However, the natural land types basically maintained a stable area, coupling with the large-scale transformation between the LUPE and LUSE types. Land use change resulted in significant spatial changes of five ecosystem services, especially carbon storage and habitat quality. The correlation analysis indicated that the five kinds of ecosystem services mainly showed a synergistic relationship, meanwhile the LUSE type denoted the most significant correlation with ecosystem services among these three category types. This study indicated that besides the protection of natural ecosystems, the LUSE type would become the key land use type in the planning and management of improving regional ecological function.

Grey Correlation Analysis of the Durability of Steel Fiber-Reinforced Concrete under Environmental Action.

The interface performance of steel fiber-reinforced concrete (SFRC) is a critical factor in determining mechanical properties and durability. The degradation of the concrete matrix and micro-structure interface is caused by environmental erosion, which shortens the service life of the structure design. Considering different volume contents of steel fiber (0%, 1%, 2%), the failure mechanism of SFRC under different environmental erosion conditions was studied through a laboratory test scheme. A total of six environmental factors are selected, including water, sodium chloride solution, sodium sulfate solution, dilute sulfuric acid solution, sodium hydroxide solution, and a freeze-thaw cycle. When subjected to different erosion concentrations and periods, micro-structure and axial bearing capacity deterioration laws are compared and analyzed. A durability equation related to fiber mixture ratio and strength is presented based on the experimental data and the numerical simulation method. The influence of different environments on steel fiber-reinforced concrete is analyzed, and the grey correlation degree of axial compressive strength is analyzed. The experimental results show that steel fiber can effectively improve the concrete axial bearing capacity, but different responses are observed under the various erosion conditions. A freeze-thaw cycle environment has the most significant impact on the axial compressive strength of concrete, followed by the sulfuric acid environment, and other environments have a weaker impact. The research results will provide a theoretical basis for predicting the performance deterioration of SFRC concerning other erosion conditions and periods.

Effect analysis of day surgery cost control based on propensity value matching / 中华医院管理杂志

Objective:To analyze the composition, the changes of expense structure and the influencing factors of hospitalization expenses, for reference in optimizing the cost control of day surgery.Methods:Collection of the first page data of patients with the top three diseases(varicose veins of lower limbs, chronic cholecystitis and varicocele)in the day surgery volume ranking in three tertiary general hospitals in a city in 2020. The confounding factors were eliminated through propensity matching. The structural change of hospitalization expenses was analyzed by structural change degree, and the influencing factors of hospitalization expenses were analyzed by grey correlation degree and multiple linear regression.Results:After 1∶1 propensity matching of the first page data of 752 patients with day surgery and non day surgery, 98 patients with lower extremity varicose veins, 356 patients with chronic cholecystitis and 38 patients with varicocele were finally included. Compared with non day hand, the total hospitalization cost of day surgical instruments decreased, and the cost structure changes of chronic cholecystitis, varicocele and varicose veins of lower limbs were 14.59%, 6.20% and 16.20% respectively. Among them, the general medical service fee, nursing fee and examination and laboratory fee showed a downward trend, and the fees of materials and drugs showed an upward trend. General medical service fee, nursing fee, examination and laboratory fee, clinical diagnosis fee, treatment fee, drug fee, material fee and other expenses presented a high correlation with the cost of day surgery(grey correlation>0.90). The payment method, wound healing type and discharge diagnosis can influence the cost of day surgery( P<0.05). Conclusions:Compared with non daytime surgery, the total hospitalization cost of day surgery has a certain cost control effect, but it can not reduce the cost of all projects. The main influencing factors are the internal composition of the cost, payment method and so on. The hospitals should focus on tapping the internal cost control potential of day surgery and further expanding the coverage of day surgery diseases.

Spatial Disparity and Influencing Factors of Coupling Coordination Development of Economy-Environment-Tourism-Traffic: A Case Study in the Middle Reaches of Yangtze River Urban Agglomerations.

In the process of rapid development of economic globalization and regional integration, the importance of urban agglomeration has become increasingly prominent. It is not only the main carrier for countries and regions to participate in international competition, but also the main place to promote regional coordination and sustainable development. Coordinated economic, environmental, tourism and traffic development is very necessary for sustainable regional development. However, the existing literature lacks research on coupling coordination of the Economy-Environment-Tourism-Traffic (EETT) system in urban agglomeration. In this study, in order to fill this gap, we establish the index system from four dimensions of economy, environment, tourism and traffic, and select the influencing factors from the natural and human perspectives to exam the spatio-temporal changes and influencing factors in the coupling coordination of the EETT system using an integrated method in the Middle Reaches of Yangtze River Urban Agglomerations (MRYRUA), China. The results indicate that the coupling coordination degree of the EETT system transitioned from the uncoordinated period to the coordinated period, while it showed an increasing trend on the whole from 1995 to 2017. The spatial agglomeration effect has been positive since 2010, while "High-High" and "Low-High" agglomeration regions were transferred from the east to the south. Land used for urban construction as a percentage of the urban area and vegetation index has a great impact on the coupling coordination degree. These results provide important guidance for the formulation of integration and coordinated development policy in the MRYRUA, and then increase China's international competitiveness by improving the contribution of urban agglomerations to GDP.
