ABSTRACT
From original concept and literature of acupoint, the concept and clinical significance of ashi method is discussed, which clarifies that the essence of ashi method is to locate the acupoints by patients' sensitivity on force. The clinical application of heat-sensitive moxibustion has illustrated that positioning method of this therapy is based on the appearance of heat-sensitive moxibustion sensation. Although both types are based on patients' feeling, positioning method of heat-sensitive moxibustion stands on a new angle and uses a new method to locate acupoint. Therefore, it is believed that the positioning method of heat-sensitive moxibustion is the inheritance and development of ashi method.

OBJECTIVE@#To determine the relationship between bone alkaline phosphatase (BAP) and cross-linked N-telopeptides of type I collegen(NTX) and bone mineral density in healthy men aged 20-80.@*METHODS@#BAP and NTX of 389 healthy men were measured by ELISA. BMD at the lumbar spine and the hip as measured by dual energy X-ray absorptiometry. The correlation of bone biochemical markers with age and BMD fit 10 regression models.@*RESULTS@#BAP and NTX negatively correlated with age. The cubic regression model was better with age-related changes of bone biochemical markers as compared with the other regression models and the coefficients of determination of fitting curve were 0.013-0.029 (P< 0.05). The value of bone biochemical markers as the highest during 20-29 age groups, then they decreased to a nadir level in the 50-59 years age. After 60 years, bone formation markers remained stable; however resorption marker increased slightly. After adjustment for age, weight, height, BMI, and smoking, bone biochemical markers were negatively correlated with most sites of BMD.@*CONCLUSION@#BAP and NTX may be relatively sensitive and specific markers to evaluate age-related changes of bone turnover. It may benefit the prevention of osteoporosis by monitoring the level of BAP and NTX.

OBJECTIVE@#To determine the relationship of serum leptin concentration and bone mineral density(BMD), body fat mass in males.@*METHODS@#Plasma concentrations of leptin in 350 Chinese males, aged 20 to 80 years were measured with ELISA; BMD values at lumbar spine, hip and total body BMD, and body composition, including lean tissue mass (LTM) and fat tissue mass (FTM), were measured using dual-energy-X-ray absorptiometry (DXA). The relationship between changes in serum leptin concentration with age, body weight, body mass index, body fat mass, and BMD values at 5 skeletal sites was fit by 10 regression models, and the models giving the best fit were selected.@*RESULTS@#The S regression model best described the changes in serum leptin level with age (R(2)=0.104, P<0.009), while the compound regression model best described the changes in serum leptin concentration with BMI and weight (R(2)=0.296, P<0.001; R(2) =0.304, P<0.001). Leptin concentration was correlated with FTM (R(2)=0.448, P<0.001) and rate of body fat(R(2)=0.461, P<0.001). The serum leptin level was significantly correlated with BMD of multiple skeletal sites (R(2) was 0.115 for anterior spine BMD, 0.102 for lateral spine BMD,0.098 for femoral neck BMD, 0.112 for total hip BMD, respectively). In a multivariate analysis, leptin concentration was not a significant predictor of BMD at any site.@*CONCLUSION@#Serum leptin concentration correlates with body fat mass and percentage of body fat, but is not a significant predictor of BMD at any site in Chinese males.
