The information entropy, H = - Pk log Pk, has been proved in this paper to be always positive and invariant for a linear coordinate transformation, so that it can be used as a measuring index. On the contrary, the integral term of the information entropy, H(x) = -f(x) log f(x) dx, is not always positive and invariant for a linear coordinate transformation. Therefore, H(x) can not be used as a measuring index. An example of a probability density function for response of nerve to electric current with different intensities is given to confirm above conclusions.

Objective To explore the feasibility of using the consensus of European Working Group on Sarcopenia in Older People(EWGSOP) to diagnose sarcopenia among community-dwelling women aged from seventy to seventy-nine in Shanghai.Methods Twenty-two healthy community-dwelling women were recruited as the subject group(group S),and another ten young girls were randomly selected as the control group(group C).The anthropometry,bioelectrical impedance analysis(BIA)and dual energy X-ray absorptionmetry(DEXA)were used to evaluate the circumferences of upper and lower limbs,and the dimension of muscle mass,according to relative appendicular skeletal mass(RASM)and skeletal muscle index(SMI).The grip dynamometer and isokinetic dynamometer were used to measure the muscle strength of upper and lower limbs.The ten meters gait speed,functional reach test,timed up and go test,Berg balance scale and short physical performance battery were all applied to assess the physical performance.The criteria of EWGSOP consensus were applied to diagnose the situation of sarcopenia.Results Firstly,the average biceps circumference and fat mass of upper limbs in group S were significantly higher than group C (P<0.01),while no significant differences were observed in the muscle mass(P>0.05).Secondly,RASM values gained from BIA and DEXA in S group were significantly higher than C group(P<0.05),while the SMI values of the former were significantly lower than the latter(P< 0.01).Thirdly,absolute grip strength,relative grip strength and other bio-mechanical indexes of lower limbs in the s group were significantly lower than the C group(P<0.01);the relative grip strength showed significant correlation with most bio-mechanical indexes of lower limbs.Fourthly,the physical performance in group S declined significantly compared with that of the c group(P<O.05),and no significant correlation was found between muscle strength and physical performance of upper limbs except the absolute grip strength and gait speed.The prevalence was 0% according to the RASM index,while the prevalence was 63.6% and 45.4% according to the BIA and DEXA respectively.Conclusion The assessing pattern from EWGSOP consensus could not be simply copied to applying on Chinese old people due to serious difference between RASM and SMI.The combination of SMI+relative grip strength+ TUG/SPPB/Berg may be better than the classical mode of RASM+absolute grip strength+gait speed in diagnosing sarcopenia.

Chinese Traditional and Herbal Drugs 2019;50(1):150-156
Objective To study the spectrum-effect relationship between GC-MS fingerprint of the volatile oil of Atractylodis Rhizoma and the dryness effect of Atractylodis Rhizoma, and clarify the main dryness components of Atractylodis Rhizoma. Methods The volatile oil of different batches of Atractylodis Rhizoma (S1-S9) were analyzed by GC-MS. Using the daily drinking amount of water, the viscosity of whole blood, and the content of aquaporin 2 (AQP2) in the kidney of rats as the indexes of dryness effect of Atractylodes Rhizome, the spectrum-effect relationship was analyzed by the combination of grey relational grade and orthogonal partial least square method. Results The dryness effect of Atractylodis Rhizoma was the combined action of multiple components, and the peaks of the major contribution to dryness effect were 31, 28, and 33, respectively. The corresponding components of the three peaks were β-eudesmol, (-)-aristolene, and bulnesol, which were identified by the spectral library retrieval analysis. Conclusion The main dryness effect components of Atractylodis Rhizoma are β-eudesmol, (-)-aristolene, and bulnesol, which provide a reference for investigating the material basis of dryness effect of Atractylodis Rhizoma.

To investigate the relationships among plasma secreted frizzled-related protein ( sfrp) 5 level and body fat parameters, glucolipid metabolism, insulin resistance index, and inflammation. 89 subjects with normal glucose tolerance(NGT) and 87 patients with type 2 diabetes mellitus (T2DM) were enrolled and each group was divided into no-obese and obese subgroups. Obesity was defined as body mass index ( BMI)≥25 kg/m2 according to the World Health Organization -Western Pacific Region diagnostic criteria ( 2000 ) . Body fat parameters were measured and BMI, waist-hip ratio were evaluated, meanwhile, the levels of blood glucose-lipid parameters and fasting insulin were also determined. Insulin resistance index ( IR) was assessed by homeostasis model assessment ( HOMA) . The concentrations of plasma sfrp5 and interleukin 6 were detected by enzyme-linked immunosorbent assay. Plasma sfrp5 level in T2DM group was significantly lower than that in NGT group [(8. 35±3. 38 vs 11. 35±3. 69)ng/ml, P<0. 01]. The levels of plasma sfrp5 in subjects with obesity were also lower than those in subjects with no-obesity in both NGT and T2DM groups [(9. 46±2. 70 vs 13. 12±3. 62)ng/ml and(6. 70±2. 34 vs 10. 12±3. 45) ng/ml, both P<0. 01]. Plasma concentrations of sfrp5 in T2DM-obese group were significantly lower than that in NGT-obese group(P<0. 01). Correlation analysis showed that plasma sfrp5 levels were negatively correlated with waist-hip ratio, HbA1C, fasting insulin, triglycerides, waist circumference, fasting plasma glucose, interleukin 6, natural logarithm of HOMA-IR [ln(HOMA-IR)], and BMI(P<0. 01 or P<0. 05). Multiple linear regression showed that ln(HOMA-IR), BMI, triglycerides were independent related factors in influencing the levels of plasma sfrp5 (r2=0. 216, 0. 177, 0. 113, all P<0. 05). Plasma sfrp5 levels were decreased in obesity and T2DM subjects and were correlated with body fat disposition, glucose-lipid metabolism, insulin resistance and inflammation. Lack of sfrp5 may contribute to the pathophysiology of obesity and T2DM.
