BackgroundThe regulatory focus theory (RFT) posits that people can pursue goals with a promotion or prevention focus. Greater alignment of RFT motivational styles between faculty and residents may enhance resident operative autonomy. This study establishes a set of faculty behaviors residents can identify to infer faculty motivational styles.Methods10 behaviors associated with promotion and prevention motivational styles were identified. General surgery residents rated faculty on how strongly they exhibit these behaviors. Faculty conducted a self-assessment of how strongly they exhibit these behaviors.ResultsThere is a positive correlation between resident and faculty ratings for the promotion-associated behaviors of “works quickly,” “high energy,” and “mostly provides broad oversight,” and for the prevention-associated behaviors of “works slowly and deliberately,” “quiet and calm,” and “preference for vigilant strategies.”ConclusionResidents can observe faculty operative behaviors to infer faculty motivational styles. Residents may use this knowledge to adjust to faculty motivational styles and enhance operative interactions.  相似文献

Purpose Our purpose was (a) to investigate relationships of baseline endocrine serum levels with selected assisted reproduction (AR) parameters and (b) to evaluate the clinical applicability of an immunofluorometric assay (IFMA) as an alternative to a radioimmunoassay (RIA).Methods Basal endocrine values (analyzed by RIA—rFSH, rLH, and rE2; analyzed by IFMA—fFSH, fLH, and fGH) were determined for female patients (n = 142) preceding ovarian stimulation for AR.Results Specific AR parameters correlated significantly with RIA- and IFMA-determined FSH levels, although IFMA correlations consistently exceeds that of RIA. Cutoff values of fFSH 11.68 IU/L or rFSH 15.0 IU/L indicated a poor response. The high-basal fFSH group was older (34 vs 31 years; P = 0.0334) and yielded fewer oocytes (2.9 vs 4.6 oocytes; P = 0.0018) than the low-basal fFSH group (<11.68 IU/L). Lower cumulative embryo scores and conception rates were also associated with the high-fFSH group, compared to the low-fFSH group.Conclusions This study confirms the negative impact of elevated basal FSH levels on AR. Basal LH, GH, and E2 levels are, in comparison to baseline FSH levels, unsuitable indices for estimating ovarian responsiveness. IFMA can be regarded as an alternative to RIA in both clinical and research laboratories.  相似文献

In order to assess the efficacy and safety of recombinant humanfollicle stimulating hormone (FSH) in routine clinical use,ovarian stimulation with recombinant human FSH was performedin 71 patients prior to in-vitro fertilization (IVF) withoutgonadotrophin-releasing hormone (GnRH) analogues in a multicentre,non-comparative study. Human chorionic gonadotrophin (HCG) wasadministered to 58 patients (81.7%), 15 of whom underwent 19cycles with an initial dosage of three ampoules daily of recombinantFSH and 43 of whom underwent 152 cycles with four ampoules dailyfrom day 3 onwards. No significant differences were detectedbetween these two groups in all test parameters. The mean durationof treatment was 9.06 and 8.86 days respectively with a meannumber of 24.06 and 23.25 vials of recombinant human FSH administered.A mean number of 6.26 and 5.88 oocytes respectively was collected.The number of transferred embryos was 2.4 and 2.2. A clinicalpregnancy rate of 23.8% (10 out of 42) per transfer was achieved(30.9 and 20.6% respectively). Local tolerance of s.c. administrationwas excellent. Mild pain at the injection site was the dominantfinding in <20% of patients. Two cases of ovarian hyperstimulationsyndrome were noted. Recombinant human FSH is very attractiveto patients because it can be self-administered s.c. and thepreparation does not come from a human source. In conclusion,these data support the safety and efficacy of recombinant humanFSH in routine use for IVF.  相似文献

近年来形态学上发现了三叉神经领域本体感觉中枢通路,在此基础上,本文用电生理学方法,通过电刺激咬肌神经和压下颌,观察了由四级神经元组成的此通路的二级(三叉神经脊束核吻侧亚核背内侧部及邻接的网状结构)、三级(沿三叉神经感觉主核内缘存在的“带状区”)中继核团以及作为最后驿站的丘脑腹后内侧核等处的单位放电反应;另外又分别刺激或损毁二、三级中继核团,观察了丘脑腹后内侧核的单位放电变化,结果证明电刺激咬肌神经和压下颌,在上述核团都出现对本体觉冲动反应的单位放电,包括兴奋性反应单位、抑制性反应单位和无关单位三种类型,以兴奋性单位为主,占神经元单位放电总数的52.9%~67.7%.分别刺激二和三级神经元的所在核团,在丘脑腹后内侧核处发生相应的单位放电效应;损毁二和三级核团,本体觉传入冲动被阻断。本研究结果从电生理学上确证了形态学上发现的三叉神经本体感觉中枢通路的客观存在,从定性研究方面支持了定位研究的结果,并填补了以往生理学上只证明初级传入核团与丘脑腹后内侧核之间存在着一条多突触联系的本体觉传递通路但未能判断其具体行径和中继部位的空白,本研究并对方法论以及一些有关问题进行了讨论.  相似文献

A 6-year-old girl with post-hepatitic severe aplastic anaemia was referred to our hospital. Haematological examination showed a haemoglobin level of 5.2 g/dl, platelet count of 8,000/l, and white blood cell count of 130/l with 17% neutrophils. She was treated with recombinant human granulocytecolony stimulating factor (15 g/kg/day i.v.) and cyclosporin A (6 mg/kg/day p.o.). The absolute neutrophil count gradually increased, but Hb and platelets were not improved. The intravenous administration of recombinant human erythropoietin (100 U/kg three times a week) was started, and the reticulocyte count reached 20000/l on day 12. The platelets increased to 81000/l after 16 months of combined administration of recombinant human granulocyte-colony stimulating factor, recombinant human erythropoietin and cyclosporin A. After 20 months of combined administration, the haematological results were: Hb, 13.1 g/dl; platelets 80000/l: WBC, 9500/l with 40% neutrophils. After recombinant human granulocyte-colony stimulating factor treatment, the myeloid elements of the bone marrow and the number of granulocyte-macrophage colony forming units increased. Bone marrow erythropoiesis and erythroid colonies also increased after recombinant human erythropoietin administration. The clinical course suggested a beneficial effect of haemopoietic growth factors and cyclosporin A in post-hepatitic aplastic anaemia.  相似文献

The present study is divided into 2 parts: The first explains the concept of stimulating plate therapy at the Muenster Clinic and the second presents a longitudinal study of mouth and tongue posture in trisomy 21 children treated with this concept.47 children underwent a pre-treatment examination (Rec1), and 38 attended a first follow-up examination (Rec2) after an average of 4 months of stimulating plate treatment. The second follow-up examination (Rec3) was on average 53 months after the end of treatment and covered 18 patients. Data acquisition was based on standardized parent questionnaires and standardized clinical examination records. Rec2 showed in part a highly significant improvement in orofacial appearance. These results were confirmed by the parent interview, according to which the mouth and tongue posture improved in 76.3% of the children during the time they were wearing the plate. Even when the plate was not in place, the result remained stable in 65.8% of the patients. Up to Rec3, further improvement was recorded in some results. The symptoms: mouth mostly wide open and tongue mostly protruding way over lips were reduced. The number of children whose tongue was mostly in the oral cavity increased correspondingly.At Rec3, the parents also rated the mouth posture in 88.9% and the tongue posture in 77.7% of the children as stable or further improved.It can be concluded from the results of this study that stimulating plate treatment in combination with physiotherapy provides a long-term improvement in the mouth and tongue posture of children with Down's syndrome.  相似文献

目的:探讨卵巢癌抗独特型单链抗体6B11scFv/hGMCSF融合蛋白质(6B11GM)作为肿瘤疫苗的可能性。方法:采用体外T细胞增殖试验,对6B11GM刺激T细胞的能力进行测定,并用流式细胞仪对T细胞表型及APCMHCⅡ表达情况进行测定,测定了外周血单个核细胞经6B11GM激活后对卵巢癌细胞系的非MHC限制的杀伤活性。结果:6B11GM及6B11均能引起特异的T细胞增殖,但6B11GM组的增殖明显高于6B11组,以CD4+增殖为主。6B11GM能明显增加抗原提呈细胞(antigenpresentingcel,APC)的MHCⅡ表达,使APC更有效地摄取抗原,激活非MHC限制的杀伤活性。结论:6B11GM能引起细胞免疫反应,作为疫苗具有良好的前景  相似文献
