RESUMEN

Dissipative structure refers to a self-organized and orderly structure that exists far from equilibrium.The human body,considered a classical example,generates negative entropy through the exchange of matter,energy,and information with the environment to counteract the increase in entropy.In this paper,we organized theories and related research on dissipative structure and entropy,discussing their significance in regulating various aspects such as the human body,cancer,aging,and more.By selecting the special population of pregnant women,focusing on the information dimension,developing the corresponding information exchange scale(Cronbach's α>0.9),and proposing the information exchange index,we preliminarily explored the influence of the dissipative structure's information dimension on pregnancy health.The results showed a negative correlation between the information exchange index and anxiety scores during pregnancy(r =-0.35,P<0.001),with an OR value of 0.26(95%CI:0.08~0.80),preliminarily confirming the feasibility of conducting empirical research based on dissipative structure theory.If further relevant empirical studies are conducted,it is expected that new disease prevention strategies will be developed and new theories and methods will be provided for the field of public health.

RESUMEN

OBJECTIVE Optimizing the water extraction technology of Xiangqin jiere granules. METHODS The orthogonal test of 3 factors and 3 levels was designed, and comprehensive scoring was conducted for the above indexes by using G1-entropy weight to obtain the optimized water extraction technology of Xiangqin jiere granules with water addition ratio, extraction time and extraction times as factors, using the contents of forsythoside A, baicalin, phillyrin, oroxylin A-7-O-β-D-glycoside, wogonoside, baicalein and wogonin, and extraction rate as evaluation indexes. BP neural network modeling was used to optimize the network model and water extraction process using the results of 9 groups of orthogonal tests as test and training data, the water addition multiple, decocting time and extraction times as input nodes, and the comprehensive score as output nodes. Then the two analysis methods were compared by verification test to find the best water extraction process parameters. RESULTS The water extraction technology optimized by the orthogonal test was 8-fold water, extracting 3 times, extracting for 1 h each time. Comprehensive score was 96.84 (RSD=0.90%). The optimal water extraction technology obtained by BP neural network modeling included 12-fold water, extracting 4 times, extracting for 0.5 h each time. The comprehensive score was 92.72 (RSD=0.77%), which was slightly lower than that of the orthogonal test. CONCLUSIONS The water extraction technology of Xiangqin jiere granules is optimized successfully in the study, which includes adding 8-fold water, extracting 3 times, and extracting for 1 hour each time.

RESUMEN

Objective To predict the potential suitable habitat of Haemaphysalis concinna in Heilongjiang Province under different climatic scenarios. Methods The geographic locations of ticks in Heilongjiang Province from 1980 to 2022 were captured from literature review and field ticks monitoring data from Harbin Center for Disease Control and Prevention in Heilongjiang Province, and the tick distribution sites with spatial correlations were removed using the software ArcGIS 10.2. The environment data under historical climatic scenarios from 1970 to 2000 and the climatic shared socioeconomic pathways (SSP) 126 scenario model from 2021 to 2040 and from 2041 to 2060 were downloaded from the WorldClim website, and the elevation (1 km, 2010), population (1 km grid population dataset of China, 2010) and annual vegetation index (1 km, 2010) data were downloaded from the Resource and Environmental Science and Data Center, Institute of Geographical Sciences and Natural Resources, Chinese Academy of Sciences. The contribution of environmental factors to H. concinna distribution was evaluated and environmental variables were screened using the software MaxEnt 3.4.1 and R package 4.1.0, and the areas of suitable habitats of H. concinna and changes in center of gravity were analyzed using the maximum entropy model in Heilongjiang Province under different climatic scenarios. In addition, the accuracy of the maximum entropy model for prediction of H. concinna distribution was assessed using the area under curve (AUC) of the receiver operating characteristic curve. Results A total of 79 H. concinna distribution sites and 24 environmental variables were collected, and 70 H. concinna distribution sites and 9 environmental factors that contributed to distribution of the potential suitable habitats of H. concinna in Heilongjiang Province were screened. The three most significant contributing factors included precipitation seasonality, annual precipitation, and mean temperature of the driest quarter, with cumulative contributions of 60.7%. The total area of suitable habitats of H. concinna was 29.05 × 104 km2 in Heilongjiang Province under historical climatic scenarios, with the center of gravity of suitable habitats located at (47.31° N, 129.16° E), while the total area of suitable habitats of H. concinna reduced by 0.97 × 104 km2 in Heilongjiang Province under the climatic SSP126 scenario from 2041 to 2060, with the center of gravity shifting to (47.70° N, 129.28° E). Conclusions The distribution of suitable habitats of H. concinna strongly correlates with temperature and humidity in Heilongjiang Province. The total area of potential suitable habitats of H. concinna may appear a tendency towards a decline with climatic changes in Heilongjiang Province, and high-, medium- and low-suitable habitats may shift.

RESUMEN

According to the theory of acupuncture-moxibustion for the treatment of spirit, starting from the relationship between eye movement and spirit, the application of electrooculogram (EOG) signal acquisition and analysis technology for the clinical treatment of spirit by acupuncture-moxibustion is discussed. Based on the nonlinear dynamic characteristics of EOG signals, it is proposed to apply the approximate entropy algorithm to extract the EOG signal characteristics in autism spectrum disorder children under different behavior states, which could realize the preliminary exploration of the correlation between EOG signals and cognitive activities. This could provide a possibility to objectively reflect the patient' s current mental state, and could be used as a potential method to grasp spirit in clinical acupuncture- moxibustion treatment. Furthermore, considering the characteristics of acupoint stimulation on the body surface, the EOG signal acquisition and analysis technology could further be combined with biofeedback technology, and a new idea for clinical acupuncture-moxibustion to treat spirit guided by biofeedback of EOG is proposed.

RESUMEN

Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual's health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique "continuous glucose monitoring" (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

RESUMEN

To study the effects of different drying methods on the quality of male flowers of Eucommia ulmoides(MFOEU), we treated fresh MFOEU samples with drying in the shade(DS), vacuum freeze drying(VFD), high-or low-temperature hot air drying(HTHAD, LTHAD), microwave drying(MD), and vacuum drying(VD), respectively. The color, total flavonoid content, total polysaccharide content, and main active components such as geniposide, geniposidic acid, rutin, chlorogenic acid, galuteolin, pinoresinol diglucoside, and aucubin in MFOEU were taken as the evaluation indicators. The quality of MFOEU was comprehensively evaluated by entropy weight method combined with color index method, partial least squares discriminant analysis and content clustering heat map. The experimental results showed that VFD and DS basically kept the original color of MFOEU. The MFOEU treated with MD had higher content of total polysaccharides, phenylpropanoids, lignans, and iridoids. The MFOEU treated with LTHAD had higher content of total flavonoids and that treated with VD had lower content of active components. According to the results of comprehensive evaluation, the quality of MFOEU dried with different methods followed the order of MD>HTHAD>VFD>LTHAD>DS>VD. Considering the color of MFOEU, the suitable drying methods were DS and VFD. Considering the color, active components, and economic benefits of MFOEU, MD was the suitable drying method. The results of this study are of a reference value for the determination of suitable methods for MFOEU processing in the producing areas.

The validation tests were conducted. The gastric ulcer model of mice was induced by intragastrical administration of anhydrous ethanol; using Compound aluminum hydroxide tablet as positive control, anti-gastric ulcer effect of Atractylodis Rhizoma was compared with that of honey bran-fried Atractylodis Rhizoma using the contents of serum inflammatory factors [interleukin-2 (IL-2), IL-6, tumor necrosis factor-α (TNF-α)], ulcer index and inhibitory rate of gastric ulcer as evaluation indexes. RESULTS The optimal processing technology of honey bran-fried Atractylodis Rhizoma was as follows:ratio of adjuvant and medicinal materials of 3∶10 (g/g), frying temperature at 140 ℃ and frying time of 4 min. Results of 3 validation tests showed that the contents of 4 components (including atractylone), in honey bran-fried Atractylodis Rhizoma processed by the optimal technology kept stable (RSDs were 3.47%-5.80%, n=3); the comprehensive scores were 95.53%-95.89% (RSD=0.21%, n=3). Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma could increase the serum content of IL-2 in mice, but reduce serum contents of IL-6 and TNF-α to varying degrees; honey bran-fried Atractylodis Rhizoma could significantly decrease its ulcer indexes (P<0.05 or P< 0.01); the improvement effect of honey bran-fried Atractylodis Rhizoma on the above indicators was generally better than that of the same dosage of Atractylodis Rhizoma (P<0.05 or P< 0.01). The inhibitory rates of low-dose, medium-dose and high-dose Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma to gastric ulcer in mice were 9.18%, 19.30%, 30.70%, and 50.32%, 61.39%, 53.16%, respectively. CONCLUSIONS The optimal processing technology of honey bran-fried Atractylodis Rhizoma is stable and feasible, and the anti-gastric ulcer effect of Atractylodis Rhizoma has been enhanced after being fried with honey bran.

RESUMEN

Objective:To optimize the different salt preparation processes of salt-processed Psoraleae Fructus and compare the differences among different salt products.Methods:Ultra-high performance liquid chromatography (UPLC) characteristic chromatogram of Psoraleae Fructus was established. By using the comprehensive scoring method, the total content of psoralen and isopsoralen and the peak area of the characteristic chromatogram were used as the evaluation index to optimize the four different processing technologies, including "stir-frying with salt-water", "steaming with salt-water", "spraying with salt-water" and "microwaving with salt-water". Meanwhile, entropy weight TOPSIS method, clustering analysis (HCA), principal component analysis (PCA) and other chemical pattern recognition methods were used to compare the quality difference of different salt-processed Psoraleae Fructus.Results:The optimized "stir-frying with salt-water" process of salt-processed Psoralea Fructus was 170 ℃ for 13 min, "steaming with salt-water" process for 1 h, "spraying with salt-water" process for 110 ℃ for 13 min and "microwaving with salt-water" process for 105 s microwave heating. TOPSIS comprehensive evaluation results of entropy weight showed that the quality of different salt products of Psoraleae Fructus ranked as product of stir-frying with salt-water > product of stir-frying with green salt-water > product of spraying with salt-water > product of microwaving with salt-water > product of steaming with salt-water; HCA results showed that different salt products of Psoraleae Fructus could be polymerized into two categories, between which product of stir-frying with salt-water and product of stir-frying with green salt-water were polymerized into one category; product of spraying with salt-water, product of microwaving with salt-water and product of steaming with salt-water were another category; the results of PCA showed that different salt products of Psoraleae Fructus could be clustered into 4 categories, among which product of stir-frying with salt-water, product of stir-frying with green salt-water and product of spraying with salt-water were clustered into the same category respectively, and product of microwaving with salt-water and product of steaming with salt-water were clustered into the same category.Conclusion:The chemical composition of Psoraleae Fructus processed by different salting methods is different. The results of this study can provide reference for processing optimization of salt-processed Psoraleae Fructus and identification of different salt products.
