摘要:Objective To describe the inference process of identifying epidemic qi as a disease cause.Methods Clauses related to epidemic qi in Wenyi Lun( Treatise on Warm Pestilence) written by Wu Youke were rearranged to analyze how he inferred epidemic qi as a disease cause with abductive reasoning. Results The discovery of epidemic qi as a disease cause is a complicated abductive reasoning process based on analogy,which contains Peirce’s adductive model and inference model for the optimal explanation. Conclusion There are some differences between the abduction structure of TCM etiology and western medicine etiology; The etiological hypothesis,which is obtained through the process of abduction,needs to be verified from the perspective of logic.

摘要:Objective To study the mechanism of Wuzi Yanzong Wan( Five-Seed Progeny Pill) on improving heat stress resistance of sertoli cells in rats based on data from the whole genome microarray.Methods Sertoli cells in primary culture were randomly divided into Wuzi Yanzong Wan( WZYZW)group,normal group and model group. The cells in three groups were given WZYZW solution and equal volume of PBS respectively. After 24 hours,rats in WZYZW group and model group were placed in water bath at 43 ℃ for 15 minutes,while rats in normal group were put in water bath at 37 ℃ for 15 minutes,then total RNA of three groups were extracted respectively and data was analyzed with gene chip technology. Results Compared with the model group,there were totally 1,203 differently genes in WZYZW group based on Sertoli cell gene expression profiles,in which 697 were down regulated and 506 were upregulated. There were totally 473 differently expressed genes in the normal group,including 168 up-regulated genes and 305 down regulated genes. Among these down-regulated gene expressions,RGD1305298,Trpt1,Dll3,Abi3 and Ppp1r12 b were significant in the WZYZW group and normal group,while Dusp7 was significant among up-regulated gene expressions. The genes mentioned above were related to cell cycle,apoptosis,cell metabolism,cell adhesion and Notch signal pathway,regulation of actin cytoskeleton,MAPK signaling pathway and tight junction pathway,etc. Conclusion The mechanism of Wuzi Yanzong pill in improving heat stress resistance of sertoli cells may involve maintenance of tight junctions between sertoli cells,inhibition of sertoli cells apoptosis and promotion of cell differentiation and maturation.
摘要:Objective To investigate the effects of extract from couple medicinals of strengthening healthy qi and eliminating pathogenic qi,i. e. Huangqi( Radix Astragali,astragalus root) and Ezhu(Rhizoma Curcumae,curcumae rhizome),and oxaliplatin( L-OHP) on inhibiting metastasis of CT26wild-type( CT26. WT) cells,and regulating CXCR3,CCR6 mRNA,and protein expression in rats with colon cancer. Methods Orthotopic transplantation model of BALB/c colon carcinoma was built in mice.L-OHP or L-OHP combined with extract from huangqi and ezhu were given to the mice model. Effects of those medicines on liver metastasis were observed. CXCR3 and CCR6 mRNA expression were measured by using RT-PCR,and CXCR3,CCR6 protein expression was detected with Western Blot. Results LOHP group and L-OHP combined with Chinese medicinal groups exhibited inhibitive effects on orthotropic tumor growth,and best effect was observed in positive expression( P < 0. 01). L-OHP combined with TCM can decrease the incidence of liver metastasis( P < 0. 05). Compared with the control group,mRNA expressions of CXCR3 and CCR6 decreased in the model group and low-dose group( P < 0. 01).Effects of L-OHP combined with low-dose Chinese medicine were more effective than other groups( P <0. 01). Compared with the control group,CXCR3 and CCR6 protein expressions decreased sinificantly in all groups( P < 0. 05 or P < 0. 01). Conclusion Mechanism of huangqi,ezhu and oxaliplatin( L-OHP)to inhibit tumor metastasis may relate to downregulation of CXCR3,CCR6 mRNA and protein expression.
摘要:Objective To observe Tau protein phosphorylation in rats with three typical patterns of senile dementia,analyzing and summarizing the specificity of phosphorylation. Methods We ligated and dissected the left and right carotid arteries at one week’s interval with intraperitoneal injection of D-galactose to establish senile dementia model in rats. Those rats then received the intervention of excessive sexual and physical exertion,high-fat feeding milk and low temperature environment respectively to establish the rat models of senile dementia with three different patterns( group K: kidney deficiency and essence loss pattern; group P: retention of phlegm and turbid substance in orifices pattern; group C: congealing cold and blood stasis pattern). Blood lipid,blood rheology and serum testosterone were measured to identify whether those model was built successfully. Different positions of Tau phosphorylation sites were measured with Western blot method. Results In the Tau protein proline-rich region,compared with the dis-eased groups,phosphorylation level increased significantly at the sites of 205 and 231 in group P. This increase was also present at sites of 181,205,and 231 in group K and 205,231 and 262 in group C. At the C-terminal region,compared with the diseased group,phosphorylation level of P group and K group were significantly increased at the sites of 404,and the increase of group C was the highest among those groups. Conclusion There is specificity at the Tau protein phosphorylation sites in each typical senile dementia pattern. This study may reveal the scientific rationale for the presence of different patterns in the same disease.

摘要:Objective To explore the correlation between frequency of ventricular premature beats(VPB) and Traditional Chinese Medicine Patterns(TCMP) based on such multivariate statistical analysis as factor analysis combined with analysis of variance or nonparametric test. Methods 428 patients with VPB were included and divided into five groups according to the frequency of premature beats. We screened the TCMP with incidence over 40% to conduct the factor analysis. Then we computed the factor scores of every participant and conducted the analysis of variance or nonparametric test based on the factor scores. Results Six component factors were identified in total: F1 were symptoms of myocardial ischemia; F2,ache and parahypnosis; F3,body fluids and mood disorders; F4,main symptoms of VPB; F5,head discomfort; F6,memory-related symptoms. Factor scores of F1,F3 and F4( Z1,Z3,Z4) were not statistically different. There were statistical difference in F2 factor scores( P < 0. 0083) when comparing VPB > 30,000/24 h group with 1,000 4,999/24 h group and < 1,000/24 h group; or when comparing 1,000 3,000/24 h group with 1,000 4,999/24 h group and < 1,000/24 h group( P <0. 008 3). Factor scores of F5( Z5) showed statistical difference between > 30,000/24 h and < 1,000/24 h groups; between 10,000 30,000/24 h and < 1,000/24 h groups( P < 0. 008 3) or facfor scores of F6( Z6) when comparing VPB > 30,000/24 h group with 5,000 9,999/24 h group and < 1,000/24 h group( P < 0. 008 3). Conclusion Participants with different VBP frequency presented myocardial ischemia symptoms of the same severity such as chest stuffiness,shortness of breath,lack of strength,body fluids disorders,mood disorders,and main patterns of VPB. The severity of ache,parahypnosis,head discomfort,and memory symptoms,however,would become more serious as the frequency of VBP increased.
