Ever since the introduction of Western biomedicine into China, there has been friction between proponents of this new approach, and proponents of the traditional medical practices that had evolved over thousands of years in China. For the most part, this friction has been couched in the unexamined assumption that Western medicine is based on science, while Chinese medicine is not. This article will examine that assumption, which in this author’s opinion is unjustified and incorrect. Having practiced acupuncture for the past 50 years, after receiving my doctoral degrees in medicine and physiology, my thinking on this topic has also evolved over time. I will begin this article with some historical information that bears on the topic under discussion, followed by my personal ideas about how to resolve the confiicts that have arisen. 展开更多

Objective To construct a precise model for identifying traditional Chinese medicine(TCM)constitutions;thereby offering optimized guidance for clinical diagnosis and treatment plan-ning;and ultimately enhancing medical efficiency and treatment outcomes.Methods First;TCM full-body inspection data acquisition equipment was employed to col-lect full-body standing images of healthy people;from which the constitutions were labelled and defined in accordance with the Constitution in Chinese Medicine Questionnaire(CCMQ);and a dataset encompassing labelled constitutions was constructed.Second;heat-suppres-sion valve(HSV)color space and improved local binary patterns(LBP)algorithm were lever-aged for the extraction of features such as facial complexion and body shape.In addition;a dual-branch deep network was employed to collect deep features from the full-body standing images.Last;the random forest(RF)algorithm was utilized to learn the extracted multifea-tures;which were subsequently employed to establish a TCM constitution identification mod-el.Accuracy;precision;and F1 score were the three measures selected to assess the perfor-mance of the model.Results It was found that the accuracy;precision;and F1 score of the proposed model based on multifeatures for identifying TCM constitutions were 0.842;0.868;and 0.790;respectively.In comparison with the identification models that encompass a single feature;either a single facial complexion feature;a body shape feature;or deep features;the accuracy of the model that incorporating all the aforementioned features was elevated by 0.105;0.105;and 0.079;the precision increased by 0.164;0.164;and 0.211;and the F1 score rose by 0.071;0.071;and 0.084;respectively.Conclusion The research findings affirmed the viability of the proposed model;which incor-porated multifeatures;including the facial complexion feature;the body shape feature;and the deep feature.In addition;by employing the proposed model;the objectification and intel-ligence of identifying constitutions in TCM practices could be optimized. 展开更多

The Qi Yuling case is a crucial juncture in the study of “fundamental rights and private law” in China, yet relevant research is underpinned on two clues. The first is that the increasing interest in the “constitutionalization of private law” worldwide provides knowledge resources and reference materials for scholars in China;the second is the understanding and exploration of the judicial application of the Constitution since the 1980s. Among them, such concepts as “the Constitution has direct legal effect” and “the Constitution needs to be implemented by the people” could have directly affected the Qi Yuling case. Focusing on such topics as the case of Qi Yuling, judicial enforcement of the Constitution, and the compilation of the Civil Code, scholars discussed the ways and scope for inclu ding fundamental rights in private law based on their experience abroad. They also looked into specific issues, covering how fundamental rights affect civil acts and the private law effects fundamental rights like personality rights, equali ty rights, freedom of speech, and protection of personal information. In the context of promoting the full implementation of the Constitution in the new era, “fundamental rights and private law” is still a field with great potential in both practice and theory. 展开更多

Depression is a common mental disease characterized by abnormal emotional changes,which belongs to the category of“melancholia syndrome”and Chinese emotion medicine.The main clinical manifestations are mood depression,loss of interest,hallucinations,self-harm,and even suicide.Etiology and pathogenesis can be divided into“inner depression”and“outer depression”,and is related to the susceptibility of the constitution.The diagnosis can be combined with four diagnoses and new techniques.Traditional Chinese medicine(TCM)treatment methods include TCM,psychotherapy,acupuncture,music therapy and so on.TCM treatment of depression has a long history,strong symptomatic,little side effects.It is forward-looking to explore new ideas of understanding and treating depression syndrome with TCM theory,which is helpful to better“prevention before disease”.TCM therapy will certainly play an important role in the treatment of depression in the future. 展开更多

From the perspective of culture-based source,the author considered that the ancient Chinese poetry and paintings not only embodied the harmony and unity thought of man and nature,but also were the emotional attachment of Chinese literati.As a diverse and comprehensive aesthetic art,landscape expressed material and spiritual culture doubly,the spiritual connotation of which was inextricably linked within ancient Chinese poetry and paintings.In addition,ancient Chinese poetry and paintings can be directly used in landscape composition,such as the widely used in plaques,inscriptions,couplets,poems and inscriptions,carved beams and painted pillars,painting with words and so on.Chinese literati integrated the ethereal realm of poetry and paintings into garden art,making landscape endow with poetic charm.Therefore,the landscape revealed the traces of literature and arts in aesthetic idea and taste,pushing Chinese garden to a higher aesthetic realm.This study pointed the right way to the future of modern landscape which advocated ecological and harmonious development. 展开更多

The electroless Ni-P-carbon nanotubes composite plating was studied on the copper substrate. Metallurgical microscope, scanning electronic microscope, X-ray diffractometer and micro hardness tester were used to study the structure, constitution and performance of the electroless Ni-P-carbon nanotubes composite deposit. Experiential results show that, with the increment of carbon nanotubes content in electroless plating solution, the grain size on the sample surface decreases whereas the density of grains and the hardness for composite deposit increases. Moreover, adding carbon nanotubes not only improves the degree of crystallization for the composite deposit but also helps their transformation from the amorphous state to the nanocrystal state. 展开更多

The diffusion of La in ε-Fe 2~3N(ε)and γ′-Fe 4N (γ′)phases produced by plasma nitriding was studied. It is found that with increasing nitriding time, the ε phase continuously decomposes into γ′ one under employed experimental conditions and compared with γ′ phase or ε+γ′ ones, the mono one ε has an impedient effect on depth of La diffusion. The growth of La layer in dual phases and mono one follows an approximate exponential law and a parabolic one, respectively, and this kinetics law does not change with increasing temperature. The effect of increasing temperature in the range of 520 to 560 ℃ on La diffusion depth is less than that of phase constitution change such as the decomposition of ε phase into γ′ one. 展开更多

Background:The constitution theory of traditional Chinese medicine(TCM)states that body constitution and disease are associated;therefore,the identification of body constitution can provide reference for disease prevention and treatment.A series of clinical studies evaluating the association between TCM constitution and metabolic syndrome(MetS)have been conducted in recent years.The aim of this systematic review is to summarize and evaluate the clinical evidence of the relationship between constitution and MetS.Methods:The PubMed,Embase,China National Knowledge Infrastructure(CNKI),Chongqing VIP,and Wanfang Data electronic databases were searched from April 2009 to July 2020.The search terms included“metabolic syndrome,”“constitution,”and“Chinese medicine.”Observational studies evaluating the relationship between body constitution of TCM and MetS were included.The primary outcome included the distribution of constitutional types in the MetS population,and odds ratio(OR)or relative risk(RR)between constitution and MetS.Effect size was expressed as proportion or OR with 95%confidence interval(CI).Methodological quality of included studies was evaluated by the NewcastleeOttawa Scale(NOS)or the American Agency for Healthcare Research and Quality(AHRQ)criteria.Results:Three caseecontrol and 26 cross-sectional studies involving 30435 cases were included.Phlegm-dampness,qi-deficiency,and damp-heat were the main constitution types in patients with MetS,accounting for 29%(22%e39%),18%(13%e24%),and 12%(9%e17%)of the population,respectively;the risk of MetS in people with phlegm-dampness and qi-deficiency constitution was 1.74[1.27,2.38]and 1.29[1.01,1.65]times higher than that in those with other constitutions.There were sex-and age-related differences in the distribution of TCM constitution in patients with MetS.Conclusion:Phlegm-dampness and qi-deficiency were associated with the occurrence of MetS.Welldesigned cohort and caseecontrol studies are needed to provide evidence for the use of TCM to prevent and treat MetS. 展开更多

Effect of laser scanning speed on phase constitution,microstructure,microhardness and wear resistance of laser-cladding hard facing alloy Stellite 12 has been investigated by means of a cross-flow-type CO_2 laser of 1.5 kW.The laser-cladding layer on the alloy consists of ma- trix phase of suppersaturated solid solution γ(Co,Cr)and complex hexagonal carbide M_7C_3.Under certain condition,at higher laser scanning speed,the suppersaturated solubility of elements increases in γ(Co,Cr),and the precipitation of the complex carbtde M_7C_3 de- creases,so the microhardness increases and the wear resistance decreases.But at slower laser scanning speed,more complex carbide M_7C_3 may precipitate,and the wear resistance may be improved.Therefore,it is believed that the principal factor in improving wear resistance is the precipitation of carbide M_7C_3,while increment of microhardness is the suppersaturated solu- bility of elements in matrix phase γ(Co,Cr). 展开更多

The pore constitution and tortuosity factor of porous TiAl intermetallic were studied on the basis of the variation behavior of pore structure parameters and the discrete particle model. The pore formation mechanism of porous TiAl is mainly ascribed to three aspects: the clearance space in green compact, the diffusive pores in the reaction process and the phase transition pores, resulting in the open porosities of 5.6%, 42.9% and 1.3%, respectively. According to the Hagen-Poiseuille equation, the tortuosity factor of porous TiAl is determined in the range of 1.3-2.2. Based on the discrete particle model and the variation rule of the tortuosity factor, the tortuosity factor depends mainly on the parameters of fabrication constant, particle shape factor, clearance distance and powder particle size. The quantitative relationships among them have been established, which can be used as the basis for adjusting the pore structure of porous intermetallics. 展开更多

This paper studies the hydrous facies of mantle-derived megacrystclinopyroxenes and pyroxenes of xenoliths of pyroxenolite and spinel peridotite as well as garnetpyroxenolite in a kimberlitic lamprophyre pipe in Anyuan, Jiangxi, by Fourier Transform Infrared(FTIR). It explores the relationship between the water content of pyroxene on the one hand and itscomposition and source depths on the other hand. All the samples contain constitution water. Spectraof the clinopyroxene are dominated by two groups of bands: 3607-3630 cm^(-1) and 3522-3542 cm^(-1).Spectra of the orthopy-roxene are dominated by three groups of bands: 3410-3424 cm^(-1), 3510-3516cm^(-1) and 3560-3595 cm^(-1). The water content of the clinopyroxenes has a positive correlationwith their FeO and Al_2O_3 contents. The source depths of mantle-derived clinopyroxene megacrysts,pyroxenolite, spinel peritotite and garnet pyroxenelite increase gradually in order. The Al_2O_3 andwater contents of four pyroxenes have similar correlation with the source depths. 展开更多

Background:We studied the consistency between two classification systems for categorizing patients:traditional Chinese medicine(TCM)constitution-based methods,versus genetic clustering.Genetic classification in constitutional identification was also evaluated.Methods:A TCM physician evaluated the constitution of each patient,according to four examinations(inspection,auscultation-olfaction,interrogation,and palpation).Those who met the criteria for Yang-deficient,Yin-deficient,and balanced constitutions were enrolled in the study.Peripheral blood samples were obtained from the participants,and peripheral blood mononuclear cells were separated from the samples within 2 hours.Total RNA extraction from the white blood cells was performed;and an Affymetrix HG-U133 Plus2.0 array was used to determine the peripheral blood gene expression profiles.The samples were classified using a support vector machine genetic classifier,and the“leave-one-out”method was used for validation.Results:The global gene expression profiles of 32 samples were grouped into three categories,and the samples in each of the gene categories corresponded with the three constitution categories.The three constitution types were distinguished using the genetic classifier with 165 genes.The accuracy of the prediction classification was greater than 95%using mathematical method.Conclusions:Participants with Yin-deficient,Yang-deficient,and balanced constitutions have varying physical characteristics and gene expression patterns.Additionally,the results from TCM constitution classification matched those obtained by genetic classification.Finally,our preliminary gene classifier distinguishes among Yin-deficient,Yang-deficient,and balanced constitutions,and provides a methodological basis for identifying the different constitutions. 展开更多
