As a medical terminology,"insidious yang"is commonly seen in ancient medical literatures of TCM,but the concept,reason and clinical significance of this term has not been illustrated comprehensively.By reviewing the ancient medical literatures and the application in modern clinic,this paper brings to light that"insidious yang"has the syndromes of interior heat and fire stagnation;and the reasons include excess yang in the interior keeping yin externally,insidious pathogenic factor in the interior transforming into heat and yang qi blocked by either visible or invisible pathogenic factors.In general,interior heat can manifest as insidious yang,insidious heat and insidious fire,according to the degree of the illness.Diagnosis must be based on the 4 diagnostic methods,and the area,the season and the condition of patient should be taken into account.Treatment of insidious yang is to clear and purge against the cause of disease.At present,the syndromes of insidious yang is commonly seen.Better therapeutic effect can be achieved when the clearing and purging herbs are applied.

Intercourse between heart and kidney and harmonization of fire and water are important concepts in TCM.At present,discussions about them are not clear,but confused.This paper concludes the concepts and meanings about intercourse between heart and kidney and harmonization of water and fire,based on opinions of ancient theories of yin and yang,and five elements.It also expounds the differences and relations about harmonization of yin and yang,harmonization of water and fire,and intercourse between heart and kidney,and puts forward that the concept of intercourse between heart and kidney should be divided into aspect in two parts which are in broad sense and in narrow sense.In broad sense,it indicates kidney qi and heart qi interacts in all aspects;in narrow sense,it indicates the intercourse between heart fire and kidney water.The pathway,the time and other meanings about intercourse between heart and kidney are also reviewed in this article.

Objective To explore the influence of different testing methods on detecting value of to-tal cell volume. Methods 60 reusable dialyzers(low-flux dialyzer and high-flux dialyzer were 30 respec-tively) were enrolled. They were divided into the traditional testing group, the modified testing group and the automatic dialyzer reuse group with 20 dialyzers in each group according to different detecting methods, the results underwent analysis. Results The basic total cell volume of the traditional testing group, the modified testing group and the automatic dialyzer reuse group were (100.10±0.25) ml, (100.13±0.50) ml and (102.00±1.41) ml in 6LR dialyzer, while in 17R dialyzer, they were (113.67±1.30) ml, (118.67±1.30) ml and (119.93±1.77)ml respectively. The total cell volume of the dialyzer reuse in the traditional testing group, the modified testing group and the automatic dialyzer reuse group were (95.20±7.76) ml, (96.20± 7.22) ml and (102.80±4.26) ml in 6LR dialyzer, while in 17R dialyzer, they were (100.00±11.48) ml, (114.35±3.31 ) ml and (117.07±2.96) ml respectively. There was significant difference between the tradi-tional and the modified testing groups in high-flux dialyzers reuse. Conclusions The modified testing method can improve the accuracy of the testing of total cell volume in high-flux dialyzer reuse.

Objective To edit Chinese version of the Minnesota living with heart failure questionnaire (MLHFQ) and to estimate its reliability and validity.Metheds Translated and edited the Chinese version of MLHFQ according to the standard procedures,and tested 83 inpatients which were recruited from three polyclinics of Beijing district in China.Results Cronbach's alpha consistency was>0.80 for the three MLHFQ scores.Reproducibility ranged from 0.48 to 0.84 for items of weighted kappa coefficient and from 0.88 to 0.94 for three do-mains of Spearman's correlation coefficient.MLHFQ scores varied significantly with NYHA functional class(P<0.05),and there were intermediate-to-high correlations with the assumed corresponding SF-36 domains(-0.73 to -0.59).Factor analysis revealed three-factor structure explained 49.34% of the total variance.The MLHFQ scores before and after the treatment combined TCM and western medicine were significant (physical domain (26.15±7.15,17.63±8.50),emotional domain (8.96±5.73,6.8l±5.31),overall score(56.38±16.88,39.77±15.69) all P<0.01).Conclusions The Chinese version of MLHFQ is translated and edited according to the standard procedures.Its reliability and validity is good,and could be used as a clinical outcome measurement.
