Purpose: Based on the National Natural Science Foundation of China, we collect and sort out the literature published in approximately the last 30 years, which use prescriptions in Synopsis of the Golden Chamber to treat pelvic inflammatory disease (PID). This study provides theoretical basis for the treatment of PID;we recommend this achievement to colleagues. Method: Firstly, we searched and collected the literatures from last three decades in CNKI, Wanfang and VIP databases, which are about classical prescriptions treating endometriosis. Then, by screening all the literatures, we obtained the clinical research literatures and individual case reports. Finally, we went through the internal quality of the two categories of literatures to get the dominant prescriptions. Using a retrospective study of evidence-based medicine research, we comprehensively collect literature, standardize the disease spectrum, classify the evidence, and then evaluate the internal quality. Results: We refine 4 prescriptions which commonly are used in the treatment of PID;in other words, they are also the clinical symptoms of PID: Gui Zhi Fu Ling Wan symptom, which manifests blood stasis and cold-damp stagnancy;Dang Gui Shao Yao San symptom, which manifests disharmony of liver and spleen, qi-blood stasis and damp obstruction;Da Huang Mu Dan Tang symptom, which manifests the gathering toxic heat and qi-blood stasis;Yi Yi Fu Zi Bai Jiang San symptom, which manifests the internal toxic heat and qi-blood injury. Conclusion: This study is gospel for the patients with recurrent episodes of PID who can’t often use antibiotics. At the same time, it is also a green therapeutics which Chinese ancients dedicated to human medicine. 展开更多

Popular fermented golden pomfret(Trachinotus ovatus)is prepared via spontaneous fermentation;however,the mechanisms underlying the regulation of its flavor development remain unclear.This study shows the roles of the complex microbiota and the dynamic changes in microbial community and flavor compounds during fish fermentation.Single-molecule real-time sequencing and molecular networking analysis revealed the correlations among different microbial genera and the relationships between microbial taxa and volatile compounds.Mechanisms underlying flavor development were also elucidated via KEGG based functional annotations.Clostridium,Shewanella,and Staphylococcus were the dominant microbial genera.Forty-nine volatile compounds were detected in the fermented fish samples,with thirteen identified as characteristic volatile compounds(ROAV>1).Volatile profiles resulted from the interactions among the microorganisms and derived enzymes,with the main metabolic pathways being amino acid biosynthesis/metabolism,carbon metabolism,and glycolysis/gluconeogenesis.This study demonstrated the approaches for distinguishing key microbiota associated with volatile compounds and monitoring the industrial production of high-quality fermented fish products. 展开更多

Heidan disease(black jaundice)is a kind of jaundice,which is caused by lingering and chronic jaundice,often with blood stasis and damp-heat,etc.The clinical symptoms of Heidan disease(black jaundice)are similar to those of cirrhosis caused by multiple chronic liver diseases in Western medicine.Heidan disease(black jaundice)generally belongs to yin jaundice type,and the pathogenesis is mostly related to blood stasis and dampness stagnation,often with damp-heat residue.According to Zhongjing Zhang,the prescription Xiaoshi Fanshi powder for the treatment of Heidan disease(black jaundice)is based on the understanding that the nature of Heidan disease(black jaundice)is inseparable from the two key pathological factors of dampness and blood stasis.The treatment of jaundice should be based on removing blood stasis and dampness,supplemented by soothing the liver and promoting the transportation function of spleen,removing blood stasis and harmonizing the collaterals,and promoting diuresis and reducing jaundice.In the treatment of jaundice,removing blood stasis and purging turbidity should be stressed,and powerful tonification should be used with caution.Since blood stasis and turbidity are always intermingling and often complicated with damp heat,the method of warm drying should be used with caution.For promoting blood circulation,removing blood stasis,and dredging the liver-biliarycollaterals,drasticmedicine shouldbeused withcaution. 展开更多

Enhancing plasma uniformity can be achieved by modifying coil and chamber structures in radio frequency inductively coupled plasma(ICP)to meet the demand for large-area and uniformly distributed plasma in industrial manufacturing.This study utilized a two-dimensional self-consistent fluid model to investigate how different coil configurations and chamber aspect ratios affect the radial uniformity of plasma in radio frequency ICP.The findings indicate that optimizing the radial spacing of the coil enhances plasma uniformity but with a reduction in electron density.Furthermore,optimizing the coil within the ICP reactor,using the interior point method in the Interior Point Optimizer significantly enhances plasma uniformity,elevating it from 56%to 96%within the range of the model sizes.Additionally,when the chamber aspect ratio k changes from 2.8 to 4.7,the plasma distribution changes from a center-high to a saddleshaped distribution.Moreover,the plasma uniformity becomes worse.Finally,adjusting process parameters,such as increasing source power and gas pressure,can enhance plasma uniformity.These findings contribute to optimizing the etching process by improving plasma radial uniformity. 展开更多

[Objectives]The paper was to evaluate the effectiveness of Xiulijing in the management of rust in Golden Delicious apple cultivation.[Methods]The Golden Delicious apple was utilized as the test material.During the young fruit stage,various dilutions of Xiulijing were applied,specifically at concentrations of 200,400,600,800,1000,and 2000 times.Additionally,both the application of a 3000-fold dilution of GA 4+7 and the practice of fruit bagging were designated as the control treatments,while a water spray was utilized as the blank control.The fruit rust index and the incidence of rust-infected fruits were evaluated to assess the effectiveness of control measures for fruit rust in Golden Delicious apple cultivation.[Results]The application of Xiulijing,with dilutions ranging from 200 to 2000 times,exhibited a significant impact on reducing both the fruit rust index and the incidence of rust-infected fruits in Golden Delicious apples.The application of a 1000-fold dilution of Xiulijing resulted in a statistically significant reduction in both the fruit rust index and the incidence of rust-infected fruits,with reduction rates of 21.1%and 31.5%,respectively.Among the various strategies for the prevention and control of apple rust,fruit bagging emerged as the most effective method.The other two technical measures demonstrated significant control effects;however,no substantial differences were observed between them.[Conclusions]The biological control agent Xiulijing is more deserving of promotion and application in practical production due to its significantly superior economic benefits,safety,and stability. 展开更多

This study sets up two new merit functions,which are minimized for the detection of real eigenvalue and complex eigenvalue to address nonlinear eigenvalue problems.For each eigen-parameter the vector variable is solved from a nonhomogeneous linear system obtained by reducing the number of eigen-equation one less,where one of the nonzero components of the eigenvector is normalized to the unit and moves the column containing that component to the right-hand side as a nonzero input vector.1D and 2D golden section search algorithms are employed to minimize the merit functions to locate real and complex eigenvalues.Simultaneously,the real and complex eigenvectors can be computed very accurately.A simpler approach to the nonlinear eigenvalue problems is proposed,which implements a normalization condition for the uniqueness of the eigenvector into the eigenequation directly.The real eigenvalues can be computed by the fictitious time integration method(FTIM),which saves computational costs compared to the one-dimensional golden section search algorithm(1D GSSA).The simpler method is also combined with the Newton iterationmethod,which is convergent very fast.All the proposed methods are easily programmed to compute the eigenvalue and eigenvector with high accuracy and efficiency. 展开更多

Objective: The paper aims to analyze the dynamic characteristics of litter production and nutrient return of the forest ecosystems in subtropical areas, and provide a theoretical basis for the nutrient cycling study in southwest Hubei Province and carbon sink function of the whole forest ecosystem. Methods: Three typical forest stands (Chinese fir plantation, Cryptomeria fortunei plantation and evergreen and deciduous broad-leaved mixed forest) in Golden Mountain Forest Farm in southwest Hubei Province were investigated and monitored continuously for the litter types and productivity and nutrient return. Results: The annual litter productivity of the three forest stands ranged from 161.77 to 396.26 kg·hm<sup>-2</sup>;Litters of branches, leaves and reproductive organs accounted for 14.14% - 20.85%, 33.26% - 78.33%, 7.52% - 42.18% of the total, respectively;The litter productivity and total litter productivity of each composition in the three forest stands show unimodal or bimodal changes over months, and the total litter productivity reached the highest value in January, April and October respectively. For different nutrient contents of the three forest stands, the common feature is C > N. The order of nutrient return amount from greatest to least is evergreen and deciduous broad-leaved mixed forest, Cryptomeria fortunei plantation and Chinese fir plantation. For different nutrient return amounts, the common feature is C > N, and the nutrient return amounts are 76.51-180.69 kg·hm<sup>-2</sup> and 2.3 - 5.71 kg·hm<sup>-2</sup> respectively. Conclusion: The annual litter productivity and nutrient return amount of the evergreen and deciduous broad-leaved mixed forest are the highest among the three forest stands. Therefore, protecting the evergreen and deciduous broad-leaved mixed forest and studying the litter changes of Chinese fir plantation and Cryptomeria fortunei plantation are of far-reaching significance for the development of sustainable forest management in this region and the further improvement of the carbon sequestration function of the whole forest ecosystem. 展开更多

In order to investigate the atmospheric oxidation processes and the formation of secondary organic aerosol (SOA), an indoor environmental reaction smog chamber are constructed and characterized. The system consists of the collapsible ~830 L FEP Teflon film main reactor, in which the atmospheric chemical reactions take place and the formation of SOA occurs under the simulated atmospheric conditions, and the diverse on-line gas- and particle-phase instrumentation, such as the proton transfer reaction mass spectrometer, the synchrotron radiation photoionization mass spectrometer, the aerosol laser time-of-flight mass spectrometer, and other traditional commercial instruments. The initial characterization experiments are described, concerning the temperature and ultraviolet light intensity, the reactivity of the pure air, the wall loss rates of gaseous compounds and particulate matter. And the initial evaluation experiments for SOA yields from the ozonolysis of α-pinene and for mass spectra of the products resulting from the photooxidation of OH initiated isoprene are also presented, which indicate the applicability of this facility on the studies of gas-phase chemical mechanisms as well as the formation of SOA expected in the atmosphere. 展开更多

The golden apple snail Pomacea canaliculata (Lamarck 1819) was first recorded at Black Dragon Spring, Dianchi Basin, Baiyi Township, Songming County, Kunming City, Yunnan Province, China, in October 2004. The water from the spring flows into the Songhuaba Reservoir, the major drinking water resource for Kunming City, and part of the Dianchi Lake basin. This is the first record of this invasive snail in the Dianchi Lake Basin. Pomacea canaliculata originates from Central and South America, and in Asia the snail has spread through deliberate and accidental introductions to the Philippines, Vietnam, Thailand, Laos, Cambodia, Malaysia, Indonesia, Papua New Guinea, Korea, Japan and South China. It has become a major pest in rice-growing areas, resulting in huge damage to crops. Strict prevention and control measures have to be implemented to prevent the spread of the snail in Yunnan, together with public awareness campaigns to inform the public of the dangers of this invasive snail. 展开更多
