ObjectiveTo present results of virological study of wild birds inhabiting Western Mongolia.MethodsOver a period of 2003–2008, we isolated 13 influenza A viruses: H1N1, H3N6, H13N8 and H4N6 subtypes. We did not isolate any H5N1 subtype, that still cause epizooty in wild birds and poultry.ResultsWe revealed taxonomic and ecological heterogeneity of the birds involved in maintenance of circulation of influenza viruses in the given territory. Influenza viruses were isolated from birds of 6 orders; among them there are species preferring water and semi-aquatic biotopes, one species preferring dry plain region, and also one species which can inhabit both dry and water biotopes.ConclusionsRepresentatives of all main orders of Western Mongolia avifauna are involved in support of influenza A virus circulation, highly pathogenic H5N1 influenza viruses were registered in Mongolia thus it's necessary to continue permanent influenza virus surveillance in wild birds' populations. 相似文献

新疆紫草颗粒剂与汤剂对药物流产效果影响的比较性研究 总被引:6,自引:1,他引:6
目的:比较新疆紫草颗粒剂与紫草汤剂对米非司酮配伍米索前列醇药物流产效果的影响,及不良反应。方法:将648例妊娠38-45 d、要求终止妊娠的妇女,随机分成3组,各组在米非司酮配伍米索前列醇药物流产时分别加服紫草颗粒剂或安慰剂或紫草汤剂,对3组的流产效果、出血时间、月经恢复时间等及不良反应进行观察。结果:紫草颗粒剂组和汤剂组的完全流产率(97.74%、97.70%)、平均出血时间(12.0±4.1 d、12.7±3.8 d)均无显著性差异(P均>0.05),且均显著优于安慰剂组(91.90%、14.3±4.8 d)(P均<0.05)。3组药物流产后月经恢复时间均无显著性差异。但紫草汤剂服用时有明显异味。结论: 紫草颗粒剂祛除了紫草的异味,服用方便,对其提高药物流产疗效与紫草汤剂相同,有必要进一步探讨。 相似文献

目的研究宫颈癌组织中Raf激酶抑制蛋白(RKIP)和核因子xBp65(NF-κBp65)的表达,探讨二者表达之间的相关性及其与宫颈癌各临床病理因素之间的关系。方法用免疫组织化学方法检测69例宫颈癌组织、37例宫颈上皮内瘤变组织和18例正常宫颈组织的RKIP和NF-κBp65表达,并分析其与宫颈癌临床病理学特征的关系。结果宫颈癌组织中RKIP的表达低于宫颈上皮内瘤变及正常宫颈组织,而NF-κBp65的表达高于宫颈上皮内瘤变及正常宫颈组织,差异有统计学意义(Hc=45.124、38.107,Z=4.309~5.159,P〈O.01);RKIP和NF—κBp65在宫颈癌组织中的表达均与临床分期、有无淋巴结转移及肿瘤分化程度有关(χ^2=5.150~11.917,P〈0.05)。宫颈癌组织中RKIP与NF-κBp65的表达呈显著负相关(r=-0.464,P〈O.01)。结论RKIP表达的减少或缺失与宫颈癌的发生、发展密切相关,RKIP表达的减少或缺失可能通过上调NF—κBp65的表达促进宫颈癌的侵袭和转移。 相似文献

Physicians' observations and interpretations of the influence of religion and spirituality on health
BACKGROUND: In spite of a substantial body of empirical data, professional disagreement persists regarding whether and how religion and spirituality (hereinafter "R/S" and treated as a single concept) influences health. This study examines the association between physicians' religious characteristics and their observations and interpretations of the influence of R/S on health. METHODS: A cross-sectional survey was mailed to a stratified, random sample of 2000 practicing US physicians from all specialties. Physicians were asked to estimate how often patients mention R/S issues, how much R/S influences health, and in what ways the influence is manifested. RESULTS: The response rate was 63%. Most physicians (56%) believed that R/S had much or very much influence on health, but few (6%) believed that R/S often changed "hard" medical outcomes. Rather, most physicians believed that R/S (1) often helps patients to cope (76%), (2) gives patients a positive state of mind (75%), and (3) provides emotional and practical support via the religious community (55%). Compared with those with low religiosity, physicians with high religiosity are substantially more likely to (1) report that patients often mention R/S issues (36% vs 11%)(P<.001); (2) believe that R/S strongly influences health (82% vs 16%) (P<.001); and (3) interpret the influence of R/S in positive rather than negative ways. CONCLUSION: Patients are likely to encounter quite different opinions about the relationship between their R/S and their health, depending on the religious characteristics of their physicians. 相似文献

Phenomenon: Vocational identity may play an important role in physicians' healthy professional development. Allopathic medical students' vocational identity may bear a relationship to the level of emphasis placed on research versus service at their medical school. Approach: Social mission score (SMS) and the US News and World Report (USNWR) research ranking (year 2011) were used as schools' national rankings for service and research, respectively. A questionnaire was sent to 960 3rd-year medical students from 24 allopathic medical schools between January and April 2011. The scale for vocational identity was created using the responses from the Vocational Identity Scale (9 items), and we used an established cutoff from a previous study to categorize those students who had “strong” vocational identity. Findings: After categorizing allopathic medical schools into four groups based on SMS rankings, we found that medical students who attended allopathic medical schools from the two highest SMS ranking groups were more likely to report scores reflecting strong vocational identities—odds ratio [OR] = 2.9, 95% confidence interval (CI) [1.8, 4.7] and OR = 2.5, 95% CI [1.6, 4.0], respectively. In contrast, we did not find any associations between students from allopathic medical schools with high USNWR rankings and likelihood of reporting scores reflecting strong vocational identities. Insights: Social mission scores for allopathic medical schools may potentially serve as predictors of professional and vocational identity development. Further research is needed to better understand these findings, as this is one of the first studies both to examine allopathic medical students' sense of vocational identity and to explore the use of SMS rankings as predictors of medical students' professional development. 相似文献

SCA6 is caused by moderate CAG expansion in the alpha1A-voltage- dependent calcium channel gene 总被引:1,自引:3,他引:1

Recently, moderate (CAG)>20 repeat expansions in the alpha1A-voltage-
dependent calcium channel gene (CACNL1A4) have been identified in a
previously unmapped type of SCA which has been named SCA6. We investigated
the (CAG)n repeat length of the CACNL1A4 gene in 733 patients with sporadic
ataxia and in 46 German families with dominantly inherited SCA which do not
harbor the SCA1, SCA2, or MJD1/SCA3 mutation, respectively. The SCA6 (CAG)n
expansion was identified in 32 patients most frequently with late
manifestation of the disease. The (CAG)n stretch of the affected allele
varied between 22 and 28 trinucleotide units and is therefore the shortest
trinucleotide repeat expansion causing spinocerebellar ataxia. The (CAG)n
repeat length is inversely correlated with the age at onset. In 11 parental
transmissions of the expanded allele no repeat instability has been
observed. Repeat instability was also not found for the normal allele
investigating 431 meioses in the CEPH families. Analyzing 248 apparently
healthy octogenerians revealed one allele of 18 repeats which is the
longest normal CAG repeat in the CACNL1A4 gene reported. The SCA6 mutation
causes the disease in approximately 10% of autosomal dominant SCA in
Germany. Most importantly, the trinucleotide expansion was observed in four
ataxia patients without obvious family history of the disease which
necessitates a search for the SCA6 (CAG)n expansion even in sporadic
patients.
