Objective To study the epidemiological features of prevalence and distribution of diabetes mellitus (DM) and the injury glucose tolerance (IGT) in elder people in Beijing. Methods Cross over sectional epidemiological survey by random stratified sampling method in elder population was applied and the middle aged people was used as controls. The prevalent status of diabetes and IGT in the population more than 60 years old in urban area was compared with that in rural areas in Beijing in 1997. Results The aggregate age adjusted standardization prevalence of diabetes and IGT were 15 98% and 15 89% , respectively in old age population in Beijing in 1997. Diabetes prevalence in 60 69 years group (only comparable data) increased about 3 2 times from 4 27% in 1981 to 13 73% in 1997. Although it was no difference in IGT prevalence between urban and rural elders, there existed significant difference for diabetes standardized rates between them(17 74% vs 8 83%). The characteristics that diabetes occurrence increased with aging has been confirmed by the correlation of diabetes prevalence to the aging in both middle age( r =1 00, P

Chinese Traditional and Herbal Drugs 2018;49(10):2432-2439
Objective Assessment of genetic diversity and genetic structure of germplasm of wild Hedysari Radix. Methods Fifteen germplasms of wild Hedysari Radix. were collected from Wudu pupolations and Tanchang pupolations. ISSR (Intersimple sequence repeat) markers were used. ISSR data were analyzed with the program POPGEN 1.32. The UPGMA tree and PCoA analysis was constructed using Ntsys software. The AMOVA analysis used Arlequin 31 software and Population structure analysis used the structure 2.3.4 software. Results The results of the ISSR-PCR showed that 126 (72.83%) of the 173 ISSR locitested were polymorphic by the nine primers. The change of percentage of polymorphic loci (PPL) of wild germplasm populations were 49.71%-61.85%. The average of PPL was 55.78%. Two populations of species level of observed number of alleles (Na), effective number of alleles (Ne), Nei's gene diversity (H), and Shannon's information index was 1.728 3, 1.364 6, 0.224 2, and 0.334 5, respectively. Total gene diversity (Ht), gene diversity with provenances (Hs), the coefficient of gene differentiation (Gst), and estimate of gene flow from Gst (Nm) of cultivated and wild population were 0.223 0, 0.192 1, 0.138 9, and 3.099 4, respectively. The among-population component accounted for 16.36% of the total variation, while the within-population component accounted for 83.64%, and genetic variation occured mainly within the population. UPGMA analysis showed that 15 samples were clustered into two branches including Ⅰ and Ⅱ. PCoA and population structure analysis confirmed the partitioning results of the UPGMA clustering. Mantel correlation test showed that there existed middle-level correlations between the genetic differentiation and geographical distance. Conclusion Our studies showed that the genetic diversity of Hedysari Radix populations was at a higher level, the characteristics of genetic structure included genetic differentiation that occurs mainly within populations and perennials, which provides theoretical basis for protecting and utilizing germplasm of Hedysari Radix resources.

Chinese Traditional and Herbal Drugs 2015;46(22):3409-3413
Objective: Taking the Hedysari Radix cultivated in different regions in Gansu province and its soil as the research objects, the correlation of contents between soil nutrients, including total N, total P, total K, organic matter, available P, available K, calycosin. and formononetin in Hedysari Radix were analyzed in this paper. Methods: The correlations of the contents between soil nutrients and active components were analyzed by the multiple comparisons, correlation analysis, and regression analysis. Results: The statistical results showed that there existed obviously positive correlations between calycosin and the contents of total N and total K of soil. Calycosin is positively correlated with the contents of organic matter and available P, while with available K and total P, it is negatively correlated. Meanwhile the contents of formononetin and total K existed significantly positive correlations. Formononetin was positively correlated with the contents of total N and available P, but it was negatively correlated with available K, organic matter, and total P. Conclusion: When the plant grows, it absorbs some ingredients of soil selectively. The accumulations of calycosin and formononetin are affected by the contents of total K, total N, and available P, which shows that the soil with higher total K, total N, and available P is conducive to the growth of Hedysari Radix.

Objective To assess the inlfuence of depth on liver stiffness measurement with real-time shear wave elastography (SWE) and determine the optimal depth for SWE in liver. Methods SWE of liver was performed on 89 healthy volunteers between May 2012 and November 2012. The depths of each liver were varied from 0 cm to 7 cm (from the liver capsule) in 1 cm increment and there were 8 depth groups in total. Then the elastic modulus of liver in each depth group were measured three times by SWE. The body mass index (BMI) and the distance from body surface to liver capsule were documented. The success rates and the mean elastic modulus of each group were calculated. Results The success rates of 0-7 cm were 0, 98.9%(88/89), 98.9%(88/89), 98.9%(88/89), 71.9%(64/89), 24.7%(22/89), 3.4%(3/89) and 0, respectively. The success rates were highest in 1 cm, 2 cm and 3 cm groups but signiifcant decreased with the increasement of depths in 4 cm, 5 cm and 6 cm groups ( 3 cm vs 4 cm, χ2=25.94, P<0.001; 4 cm vs 5 cm, χ2=39.68, P<0.001;5 cm vs 6 cm,χ2=16.79, P<0.001). The mean elastic modulus of 1 cm, 2 cm, 3 cm, 4 cm and 5 cm groups were (4.77±0.99), (4.68±0.99), (4.76±0.95), (5.19±1.10) and (5.41±0.95) kPa, respectively. The mean elastic modulus of 4 cm and 5 cm groups were signiifcant higher than those of 1 cm, 2 cm, 3 cm groups (4 cm vs 1 cm, t=-2.85, P=0.005;4 cm vs 2 cm, t=-3.49, P=0.001;4 cm vs 3 cm, t=-2.76, P=0.006;5 cm vs 1 cm, t=-3.13, P=0.002;5 cm vs 2 cm, t=-3.66, P=0.000;5 cm vs 3 cm, t=-3.05, P=0.003). In the group of 4 cm, the BMI and the distance from body surface to liver capsule of the volunteers performed successfully and unsuccessfully were (20.70±2.87), (22.07±2.42) kg/m2 and (1.45±0.25 ), (1.60±0.29) cm, respectively. In the group of 5 cm, the BMI and the distance from body surface to liver capsule of the volunteers performed successfully and unsuccessfully were (19.82±2.76), (21.49±2.72) kg/m2 and (1.35±0.21), (1.54±0.26) cm respectively. The BMI had no signiifcant difference between the successful and unsuccessful groups (t=-2.83, P=0.108 for 4 cm;t=0.77, P=0.709 for 5 cm), but the distance from body surface to liver capsule was signiifcantly different (t=26.51, P=0.012 for 4 cm;t=79.57, P=0.004 for 5 cm). Conclusions The success rates and elastic modulus were different at different depths. SWE should be performed at the depths of 1-3 cm from the liver capsule.

Photothermal therapy (PTT) is a highly effective anti-tumor method. However, when laser radiation was used to ablate tumors, it usually triggers a series of inflammatory reactions, promoting the further development of tumors and affecting the effect of anti-tumor therapy. Therefore, it is an effective method to improve the anti-tumor effect by suppressing the inflammatory response through the precise targeted delivery of anti-inflammatory drug while realizing the photothermal treatment of tumors. To this end, the redox-responsive linker 3,3'-dithiodipropionic acid was used to bond the classic hydrophobic anti-inflammatory drug 18
