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

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

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

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

The results of this experiment show that LWDHTcan increase markedly the number of lymphocytes, mainly T lymphocytes, in tumor--bearingmice. Free--flow electrophoresis shows that in tumor--bearing mice the electrophoretic char-acteristics of T lymphocytes are changed, i.e., reduction of the number of T lymphocyteswith a higher electrophoretic rate, but LWDHT can alleviate this disorder. Study on the cellmembrane fluidity of carcinoma cells in EAC mice demonstrates that LWDHT can decreasethe cell membrane fluidity. suggesting that it can inhibit division of carcinoma展开更多

文摘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.

文摘Background:Metabolic diseases pose considerable burden on the healthcare system worldwide,indicating the significance of prevention and treatment.In constitution theory of traditional Chinese medicine,phlegm-dampness constitution(PDC)is the common basis of metabolic diseases.In clinical practice,Huatan Qushi(HTQS)decoction targeting on PDC can effectively improve metabolic indicators.However,its underlying biochemical mechanism still remains unclear.Methods:Eight PDC participants received HTQS decoction for three months.Their blood was collected at baseline and 1 and 3 months after intervention started.Related biomedical indicators were detected.High-throughput sequencing and RT-qPCR were used for validation.Due to the missing data,repeated measures with missing values in mixed models were used.Results:After 3-month treatment,HDL-C level increased(P<.001)and FBG,FINS,and HbA1c all showed decreasing trend at different time points(all P<.05).After miRNA high-throughput sequencing,compared with the baseline,differential miRNAs at 1 and 3 months were screened,and target gene prediction and KEGG pathway enrichment analysis were performed.The results displayed that metabolic disease-related pathways mainly included pathways in cancer,PI3K-Akt signaling pathway,etc.Further,RT-qPCR showed that hsa-miR-1237e3p differed statistically(P=.008).Then we validated the target genes of hsa-miR-1237e3p in the“Pathways in Cancer”pathway including SDF1,AC,CRK,and HGF,also known as upstream target genes of PI3K/AKT pathway.The results showed that two indicators of CRK and HGF were in statistical significance(P=.045 and P=.036,respectively).Conclusion:PDC serves as a common basis for various metabolic diseases.Through adjusting PDC,HTQS decoction can improve biomedical indicators including blood glucose,HbA1c,insulin,and HDL-C.The target pathway is“Pathways in cancer”.Specifically,HTQS decoction acts on targets of CRK and HGF by regulating hsa-miR-1237e3p,and probably exerts effects on their downstream PI3K/AKT pathway.

文摘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.
