Effects of Astragalus Powder on Serum Lipid and Body Fat Content of Fast Large-scale Quality Chickens

[ Objective] To study the effects of astragalus powder on serum lipids and body fat contents of fast large-scale quality chickens, and thus provide a theoretical basis for its application in poultry production,[ Method ] All the 180 1-day-old healthy Liangfeng chickens were randomly divided into six groups. Group 1 was the control group, fed with basal diet; group 2, group 3 and group 4 were fed with basal diet added with 0.75%, 1.0% and 1.25% astragalus powder, respectively; group 5 and group 6 were separately fed with basal diet added with 1.0% and 1.25% astragalus pow- der, but the astragalus powder was used for 10 d and then was forbidden for 10 d in turn during the whole experiment. The content of triglyceride （TG）, total cholesterol （TCHO）, high-density lipoprotein-Cholesterol （ HDL-C）, and low-density lipoprotein-Cholesterol （LDL-C） were respectively determined when the chickens were 35-day-old and 63-day-old, while the percentage of abdominal fat （PAF） as well as intramuscular fat （IMF） and subcutaneous fat ply （SFP） was measured when the chickens were 63-day-old. [ Result] In 35-day-old chickens, the levels of TCHO were sig- nificantly or very significantly lower in group 3, group 4, and group 6 than in control group （ P 〈0.05 or 0.01 ） ; the levels of LDL-C significantly lower in group 3 and group 6 （ P〈0. 05） ; the level of HDL-C significantly higher in group 5 （P〈0.05）. In 63-day-old chickens, the levels of TCHO and LDL-C were significantly or very significantly lower in group 3, group 4, and group 5 than in control group （ P 〈 0.05 or 0.01 ） while the levels of HDL-C were significantly higher in these groups; the PAF was significantly lower in group 3 （ P 〈 0.05）. [ Condasion] Astragalus powder should re- duce the levels of TG, TCHO and LDL-C, promote HDL-C content, and also play a certain regulative role in deposition of abdominal fat.

The Planning, Organization and Management of Post-disaster Reconstruction of the Lushan Earthquake Based on the Local as the Main Body

A new organization and management mechanism with the local government as the main body was created during the post-disaster reconstruction of the "4. 20 " Lushan earthquake,in which the experiences and lessons were drawn from the "5. 12"Wenchuan earthquake. Correspondingly, the local government conducted an exploration of the organization and management mode in the field of planning and construction. The effective experiences have been accumulated, including working out a full coverage planning,taking the leading part in the urban-rural planning,and exercising whole space control over the disaster area. An innovation management mode named as "Five Generals Pattern"was implemented in the construction projects. In view that the rural housing reconstruction was a weak link, a new approach to improving the construction management was investigated,by means of strengthening on-site supervision,establishing a technical platform,and bolstering public participation.

Dynamic genetic analysis for body weight and main length ratio in turbot Scophthalmus maximus

The objective of this study was to estimate genetic parameters of body width(BW)to body length(BL)ratio(BW/BL)and of body weight traits(BWT)in turbot,and to elucidate the genetic mechanism of the two traits during ontogeny by dynamic genetic analysis.From 3 to 27 months,BW,BL and BWT of each communally stocked fish were measured every 3 months.The BW/BL ratio was measured at different sampling ages.A twotrait animal model was used for genetic evaluation of traits.The results showed that the heritability values of BW/BL ratio ranged from 0.2168 to 0.3148,corresponding to moderate heritability.The BWT heritability values ranged from 0.2702 to 0.3479 corresponding to moderate heritability.The heritability of BW/BL ratio was lower than that of BWT,except at 3 months of age.Genetic correlation between BW/BL ratio and BWT decreased throughout the measurement period.Genetic correlations were higher than the phenotypic correlations.The current results for estimating genetic parameters demonstrate that the BW/BL ratio could be used as a phenotypic marker of fast-growing turbot,and the BW/BL ratio and BWT could be improved simultaneously through selective breeding.

Study of main body element of crustal strain and its relationship with moderate-strong earthquakes

In this paper, progress in strain study of blocks and faults by GPS data are discussed, and the concept that active structures between blocks are the main body of crustal strain is clarified. By energy transfer principle of elastic mechanics, the relation between strain around faults and tectonic force on fault surfaces is set up and main body element model of crustal strain is constructed. Finally, the relation between mechanical evolution of model and seismogenic process of Kunlun earthquake （Ms=8.1） is discussed by continuous GPS data of datum stations. The result suggests that the relatively relaxed change under background of strong compressing and shearing may help to trigger moderate-strong earthquakes.

Research on Characteristics of Main Body and Role of Farmers and Government in Socialist New Village Construction

This paper expounds the connotation of main body of new socialist village construction,and the duplex main body characteristics of farmers and government.It points out that the main body of society should be the state holding public power,and the main body of nature or practice is the farmer who participates in production and living activities in rural areas and supports the existence of rural society.It also expounds the dominant position of duplex main body in new village construction,wherein the government is the main body which administers public power in the field of public power in new village construction,while the farmer is the main body who administers private rights in the field of non-public rights in new village construction.It generalizes and unravels the role of duplex main body of farmers and government in new village construction,and analyzes the relationship of role of duplex main body between government and farmers as follows:the government dominates over rural development,and the government,as main body,plays dominant role in the field of rural public power and construction of social environment,while the farmers are main participators and constructors,who play significant role;in construction of rural non-public power field,the farmers play the role of main body,and the government plays the role of guidance and service.In new village construction,the government and farmers play the role abreast,which is an important prerequisite and guarantee of constructing new village.In the process of government's fulfilling responsibility in new village construction,the outdated administrative concept exists,and in the process of administering and promoting new village construction,the farmers' quality is yet to be promoted.As for these problems,three countermeasures are put forward as follows:transform concept;transform style of work and transform and exert advantage of organization.

ELEMENTAL CONTENTS IN ORGANS AND TISSUES OF CHINESE ADULT MEN

Objective To provide basis of reference values for relevant parameters of Chinese Reference Man. Methods Eighteen kinds of major organ or tissue samples, including muscle, rib, liver, and so on, were obtained from 4 areas (Hebei, Shanxi, Jiangsu, and Sichuan provinces) with different dietary patterns in China in autopsy of 16 healthy adult men, who had just encountered sudden deaths. At the same time, whole blood samples were collected from 10 volunteers living in each of these areas. The concentrations of 56 elements in these samples were detected by using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), and Graphite Furnace Atomic Absorption Spectrometry (GF-AAS) techniques. Based on obtained concentrations and reference values of these organ or tissue weights for Chinese Reference Man, the relative elemental burdens in these organs or tissues as well whole body were also estimated. Results The concentrations of 56 elements in 18 main organs or tissues were determined all together and their elemental organ or tissue and whole body burdens were estimated. Furthermore, the distributions of important elements for radiation protection in these organs or tissues were emphatically discussed. Conclusion By summing with past related results, the total results obtained from the series of research may provide more reliable and better representative basis of these reference values for Chinese Reference Man than before.

Effect of Salinity on the Growth Performance, Body Composition, Antioxidant Indexes of Perinereis aibuhitensis and Total Nitrogen in the Substrate

In this study, the effects of different salinity levels (9, 12, 15, 18, 21, 24, 27, 30, and 33) on the growth performance, body composition, antioxidant indexes of Perinereis aibuhitensis (initial average mass, 20.4 ± 0.3 mg) and total nitrogen in the substrate were investigated. The survival rate, specific growth rate, feed coefficient, and protein efficiency ratio under different salinity levels were measured. The results showed that the survival rate of P. aibuhitensis at the salinity level of 9 was significantly lower than that of P. aibuhitensis at other salinity levels (P P. aibuhitensis at other salinity levels was not significant (P > 0.05). On the basis of quadratic polynomial fitting of the relationship between salinity levels and the specific growth rate, feed coefficient, and protein efficiency ratio, it was concluded that 25.36 - 25.9 is the most suitable salinity range for the growth performance of P. aibuhitensis. The main body composition (moisture, crude fat, crude protein, and ash content) was measured at different salinity levels. The results indicated that, with the increase in salinity, the moisture content of P. aibuhitensis decreased gradually;in contrast, the ash content increased gradually, as the salinity level increased. However, in the salinity range of 18 to 33, the difference in ash content was not significant (P > 0.05). Salinity had a significant influence on the crude protein content (P P. aibuhitensis specimens were cultured for 60 days was higher than the total nitrogen in the soil. With an increase in salinity, the total nitrogen content first decreased and then increased, and the lowest value was observed at the salinity level of about 24.

INFLUENCE OF CARBON CONTENT OF MARTENSITE STEELS ON HARDNESS RE-DISTRIBUTION NEAR WORN SURFACE

After three-body abrasion, the hardness re-distribution near the worn surface has a close relationship with the carbon content of martensite steel. It is considered that there is a competition between the work-hardening and the temper softening, which results from deformation and friction heat of material. When the carbon content of martensite steel is below about 0.6%, the subsurface hardness distribution of material is a softened layer sandwiched between two hardened layers, but above 0.6%C, no softened region appears on the hardness re-distribution curve.
