Some biological and biochemical characteristics of metacercaria of Euparagonimus ce-nocopiosus obtained from crabs in the mountainous area of south Anhui, were compared with those of Paragonimus westermani from the same batch of crabs.The metacercariae of E. cenocopiosus prefer the location in heart rather than in the muscle of crabs. The average infection rate of crabs was 42.8% by E. cenocopiosus, while that by P. westermani was 100%. The infection rate of rats with E. cenocopiosus was 3/6 and 10/10 with P. westermani and the recovery rate of worm of these two species was 4.5-8.8% and 22-72.2% respectively. The number and pattern of protein bands of metacercaria of these two species by disc-PAGE and IEF technics were different.

Objective To boost the transformation and sustainable development of medical scientific achievements. Methods Investigations in the form of questionnaires were made and descriptive statistics was conducted. Results Eighty to ninety percent of the achievements awards were allocated to the research project teams or the principal prize winners. Most of the achievements transformation awards were retained by the units while only ten to twenty percent went to the principal awardees and only two to three percent went to the management and intermediary personnel. There also existed such problems as weak awareness of achievements transformation and lack of scientificalness in the achievements review and evaluation system, assessment system and assessment indexes. Conclusion The awareness of scientific achievements transformation should be enhanced and the transformation should be implemented on a market oriented and commercial basis; the scientificalness of achievements review and evaluation should be improved; more awards should be given and more social fundraising activities should be conducted; and scientific research management should be included among the factors to be considered when allocating money awards.

To reveal the mechanism of Cu enrichment of alfalfa, in-situ micro-X-ray fluorescence spectrometry (μ-XRF) and fractional extraction were used to explore in-situ Cu distribution information in alfalfa seedlings and different combination forms of Cu in organs.The results showed that alfalfa roots were enriched with Cu up to 12.06 mg/g, which was 8 times of stem and 4.9 times of leaves.The in-situ μ-XRF result showed that the root of alfalfa was the main site of enrichment of Cu, and there was a barrier of Cu at the rhizome junction to alleviate the toxic effect of excess Cu on the shoots.Excess Cu (more than 50 μmol/L) also inhibited the uptake of Zn and Ca in alfalfa, enhanced the uptake of Fe in alfalfa, but had no obvious effect on the uptake of K and Mn.Plant fractional extraction showed that the Cu in root cells was mainly fixed in the form of insoluble residues (41%) and cell wall chelate (20%), while in the stem, Cu existed as four forms including hydrophobic protein binding, cell wall binding state, residual state and water-soluble state, which further reduce the excess transport of Cu to the leaves.In the leaves, excess Cu in the leaf cells was mainly in the vacuole and insoluble residue to achieve tolerance and detoxification to Cu.

Objective To explore the related factors that affect the incidence of uterine fibroids to provide a theoretical basis for the clinical diagnosis and prevention.Methods Based on the clinical data selected from June 2014 to July 2016 in pathology of our hospital,159 cases of patients were confirmed with uterine fibroids,a comparative study was employed and the single factor test and the logistic regression analysis were both used to analyze the related risk factors that affecting the incidence of uterine fibroids.Results There were all significant level (P ＜ 0.05) between case and control groups in 40 years to 50 years,the number of abortions (≥2) as well as gynecological diseases,which were the independent factors for the incidence of uterine fibroids.In the present,the regression coefficients of former two factors were 0.186 (P ＜ O.05),and 0.584 (P ＜ 0.05),respectively.The corresponding regression coefficients of breast hyperplasia,vaginitis,cervicitis,endometritis and pelvic inflammatory disease,and other gynecological diseases and gynecological diseases were 0.221 (P ＜ 0.05),O.363 (P ＜ 0.05),O.539 (P ＜ 0.05),0.361 (P ＜ 0.05),and 0338 (P ＜ 0.05),respectively.It suggests that these were independent factors affecting the incidence of uterine fibroids.Conclusions The more the increasing age and the number of abortions,kinds of gynecological diseases infected will increase the risk of patients suffering from uterine fibroids.

During the resistance to SARS, medical staff's medical ethics accumulation reflects generously. The test of SARS has promoted the medical staff's social responsibility consciousness, strengthened the coordination between each other and sublimed the morals in the whole society. Therefore, the sufficient realization of the accumulation of medical ethics depends on the enhancement of hygiene industry input;the display of the accumulation of medical ethics depends on the positive propaganda and encouragement to medical staff; the expansion of the medical ethics epitaxy depends on the fully excavation and utilization of the accumulation of medical ethics.
