Eighteen litters of piglets（total 212） were randomly allocated to 2 groups and were fed a creep feed diet with or without in-feed antibiotics（olaquindox, oxytetracycline calcium and kitasamycin） from postnatal d 7 to d 42. On d 42, the piglets within the control or antibiotic group were mixed, respectively, and then further randomly assigned to a normal-（20%, 18%, and 14% CP from d 42 to d 77, d 77 to d 120, and d 120 to d 185,respectively） or a low-CP diet（16%, 14%, and 10% CP from d 42 to d 77, d 77 to d 120, and d 120 to d 185,respectively）, generating 4 groups. On d 77（short-term） and d 185（long-term）, serum and fecal samples were obtained for blood parameters, microbial composition and microbial metabolism analysis.Results： EAI increased（P 〈 0.05） albumin and glucose concentrations in low-CP diet on d 77, and increased（P 〈 0.05） urea concentration in normal-CP diet. On d 185, EAI increased（P 〈 0.05） globulin concentration in normal-CP diets, but decreased glucose concentration. For nutrient digestibility, EAI increased（P 〈 0.05）digestibility of CP on d 77. For fecal microbiota, the EAI as well as low-CP diet decreased（P 〈 0.05） E. coli count on d 77. For fecal metabolites, on d 77, EAI decreased（P 〈 0.05） total amines concentration but increased skatole concentration in low-CP diet. On d 185, the EAI increased（P 〈 0.05） putrescine and total amines concentrations in low-CP diets but reduced（P 〈 0.05） in the normal-CP diets. The low-CP diet decreased the concentrations of these compounds.Conclusions： Collectively, these results indicate that EAI has short-term effects on the blood parameters and fecal microbial fermentation profile. The effects of EAI varied between CP levels, which was characterized by the significant alteration of glucose and putrescine concentration.展开更多

Methods: 76 patients with newly diagnosed early chronic phase CGL received treatment of merely 1.5 mg/m2 daily HHT for induction remission and long-term maintenance treatment. The apoptosis rate of bone marrow CD34+ cells induced by HHT was assayed with flow cytometer. Results: 86.8% patients achieved CHR, 13.2% patients PHR and 31.8% patients got cytogenetic response in HHT treatment group, which was longer than 31 (8-54) months in hydroxyurea (HU) group (P<0.05). The effect of apoptosis induction HHT was stronger on CGL-CP patients bone marrow CD34+ cells than on normal person bone marrow CD34+ cells. Conclusion: HHT is a very effective drug for remission induction and long-term maintenance treatment in early chronic phase CGL patients.展开更多

Long term thermal aging tests for DD5 single crystal superalloy were carried out at 1,100 ℃ for 20, 100, 200, 500 and 1000 h, and then cooled by air. The effect of long term thermal aging on the dislocation networks at the γ/γ' interfaces was investigated by FE-SEM. Results showed that during the long term thermal aging at 1,100 ℃, misfit dislocations formed firstly and then reorientation in the(001) interfacial planes occurred. Different types of square or rectangular dislocation network form by dislocation reaction. Square dislocation networks consisting of four groups of dislocations can transform into octagonal dislocation networks, and then form another square dislocation network by dislocation reaction. Rectangular dislocation networks can also transform into hexagonal dislocation networks. The interfacial dislocation networks promote the γ' phase rafting process. The dislocation networks spacings become smaller and smaller, leading to the effective lattice misfit increasing from-0.10% to-0.32%.展开更多

Continuous compost application, especially at a high level (30 Mg·ha<sup>-1</sup>·y<sup>-1</sup>), into the double cropping soils increased the activities of organic C-, N-, and P-decomposing enzymes and the contents of organic C, total N, and microbial biomass N, as well as the cation exchange capacity, thereby contributing to the enhancement of soil fertility. Also, the compost application increased the degree of water-stable soil macroaggregation (>0.25 mm), which was correlated significantly (r > 0.950, p < 0.05) with the contents of hydrolyzable carbohydrates (with negative charge) and active Al (with positive charge), and resulted in the modification of soil physical properties. Furthermore, the application increased the amount of soil organic matter, including humic acid with a low degree of darkening and fulvic acid, and contributed to C sequestration and storage. Physical fractionation of soil indicated that about 60% of soil organic C was distributed in the silt-sized (2 - 20 μm) aggregate and clay-sized (<2 μm) aggregate fractions, while about 30% existed in the decayed plant fractions (53 - 2000 μm). The results obtained unambiguously indicate that long-term application of compost can improve soil qualities in the field subjected to double cropping, depending on the amount applied.展开更多

The asymptotic probability distributions of the central statistics are presented, and compared with empirical bootstrap estimates. Bootstrapped distributions are calculated from reference data obtained during 1999–2000 and used to develop change-point alarm criteria for the structure, using reasonable sensitivity measures developed from FEM simulations and structural analysis. The implications of the frequency data are discussed in conjunction with the strain and displacement measurements in order to discern if the load carrying capacity of the bridge has been affected. The critical need for more advanced temperature compensation models for large structures continually in thermal disequilibrium is discussed.展开更多

The most concerned diseases are chronic inflammatory diseases. Its use may be either short-term or long-term, thus generating several side effects, some of which are conventional and known, but others are rare, such as Kaposi’s sarcoma. We report here a particular clinical observation. Observation: This is a patient of 37 years, who consults in Internal Medicine for the treatment of mucocutaneous lesions, papular nodular, hyper pigmented, budding and disseminated appeared after six months of corticosteroid therapy. This treatment was introduced for the treatment of acoustic neurinoma. The patient is not diabetic or alcoholic and has a negative HIV status. The diagnosis of Kaposi’s sarcoma was made by histology of biopsied skin lesions which concluded for a regular proliferation without atypia spindle cell or mitosis. The lesions persisted over a month despite discontinuation of corticosteroid therapy. Treatment with Bleomycin was necessary. The outcome was favorable under treatment with progressive and complete disappearance of lesions after 15 treatments. Conclusion: The classical side effects of long-term corticosteroid are known, but Kaposi sarcoma complicating long-term corticosteroid is rare in the literature. It is vital that any long-term corticosteroid should be the subject of careful and regular monitoring.展开更多

With the gradual aging of the elderly, loss of energy, loss of energy has become the norm for the elderly or sick elderly. According to the Ministry of Civil Affairs statistics, as of the end of 2014, the number of disabled elderly in China reached 35 million, about 90% of the disabled elderly need professional care services and professional treatment to ease the pain. In order to deal with the social problems brought about by the aging of the population, in July 1, 2012, Qingdao City, the first in the country to establish a long-term health care insurance system, has taken a key step to crack the problem of aging. In this paper, the situation of Qingdao long term care insurance system as the research object, taking Qingdao city as study sites, according to statistical data analysis of the implementation effect of long-term local health care policy, and through questionnaires and interviews in the form of local residents to participate in the investigation of awareness, and perception.

The inhibition of the fibre response outlasted the period of acupuncture for more than 30 min. Neither Anor C-fibre responses in the remaining 23 neurous could be affected by manual acupuncture. These results suggest that the acupuncture stimulation specifically influences nociceptive nociceptive transmission,maybe through a presynaptic action,Furthermore, the fact that the inhibitory effect outlasts the stimulation by more than 30 min indicates that either a neuromodulatory ,presumably peptidergic action is at hand or that a temporary synaptic modification occurs in the spinal dorsal horn.展开更多
