情智为什么比智商更准确?

IQ的缺点关于智力的理解,有没有一致的意见呢?智商即"IQ"并不全部的说明一个人在世界的成功或者失败。事实上,大部分的研究智力的社会学家估计智商只说明了20%～30%的成果。即使支持者断言说,智商是"最著名的预报值",例如金融投资的成功,但这些数值不是你可以打赌的。     

Treatment of severe acute lung allograft rejection with OKT3 and temporary extracorporeal membrane oxygenation bridging.

OBJECTIVES: The use of OKT3 for treatment of advanced high-grade acute rejection episodes eventually can result in cytokine release and consecutive pulmonary edema. Temporary extracorporeal membrane oxygenation (ECMO) bridging can be used to overcome this crucial period before the beneficial effects of OKT3 can be observed. METHODS: We summarize our experience with three patients, who underwent lung transplantation and presented with severe acute rejection episodes. OKT3 had to be initiated due to insufficient response to standard rejection therapy with corticosteroids. Upon initiation of OKT3 treatment, a massive life-threatening deterioration of lung function in spite of heavily invasive respirator treatment was seen and temporary ECMO support was imperative to support graft function. Results of this treatment were retrospectively reviewed. RESULTS: In all cases femoro-femoral veno-arterial ECMO was used for support of the impaired graft and after a period of 4-5 days led to a massive improvement of graft function. In the further course two patients could be discharged from hospital and are still alive 30 and 36 months, respectively, after the described incident. One patient died 4 months later due to liver failure. CONCLUSIONS: We conclude that the use of ECMO support in patients experiencing significant side effects from OKT3 therapy is a useful and effective therapeutic tool to overcome the initial critical period until the lung has sufficiently recovered.     

Bioimpedance analysis highlights changes in body composition at the early stages of impairment of kidney transplant function.

OBJECTIVE: Kidney transplantation restores renal filtration, although it does not achieve the function of 2 native kidneys, and with time it may involute back to chronic renal failure. We hypothesized that bioelectrical impedance analysis (BIA) might highlight differences for body compartments among kidney transplants (Tx) with different filtration rates. METHODS: Thirty transplantation patients (19 male, 11 female) were studied at 62.4+/-26.6 months postsurgery and were divided into 3 groups: good creatinine clearance (crCl, mL/min/1.73 m2; >65.0), borderline (35.0相似文献   

Nocturnal growth hormone secretion in schizophrenic patients and healthy subjects.

Plasma growth hormone concentrations were measured at hourly intervals between 10 p.m. and 8 a.m. the next morning in 15 drug-free chronic schizophrenic male inpatients and 14 healthy males. Growth hormone secretion was significantly lower in the patients as compared with the controls. Growth hormone release peaked around 1 a.m. in the controls, but a growth hormone peak was absent in the patient group. Increased dopamine activity, increased serotonin activity, or both could explain the absence of a nocturnal growth hormone surge in the schizophrenic patients.     

Re-operations of supratentorial anaplastic astrocytomas

Summary Results of re-operations of 99 adult patients with recurrent supratentorial lobar glioblastomas (60 patients) and anaplastic astrocytomas (39 patients) have been reviewed. In all cases both surgical interventions were performed at the same institute. Age of patients with glioblastoma varied between 19 and 64 and with anaplastic astrocytoma between 21 and 68 years, with a mean value of 48 and 36 years, respectively. The median interval between the first and second operations was 47 weeks for patients with glioblastoma and 83 weeks with anaplastic astrocytoma. The mortality rate of the re-operations was 3%. Following re-operation radio-and/or chemotherapy was applied in most of the cases. Median survival time after re-operation was 18.5 weeks in patients with glioblastoma and 55 weeks with anaplastic astrocytoma. Survival curves were calculated according to Kaplan-Meier method and for statistical evaluation the generalized Wilcoxon test and multiple linear regression method were used. Histologically lower grade tumour at the first operation and longer interval between the two operations proved to influence positively and differentiation of the primary tumour negatively the survival time.     

Progressive multifocal leukoencephalopathy in a lung transplant recipient.

Progressive multifocal leukoencephalopathy (PML) is a sub-acute, demyelinating disease of the brain caused by a human polyomavirus. We describe a patient with the onset of PML 7 months after lung transplantation. The patient was treated with immunosuppressive modulation and cidofovir, a new anti-viral therapy for PML, with stabilization of the symptoms. We also review the 4 additional reports in the literature of PML after heart and lung transplantation. Progressive multifocal leukoencephalopathy may become more prevalent as the population of heart and lung transplantation recipients increases.     

Biochemical changes after a qigong program: lipids, serum enzymes, urea, and creatinine in healthy subjects.

BACKGROUND: The aim of the present study was to analyze the effects of a qigong training program on blood biochemical parameters. MATERIAL/METHODS: Twenty-nine healthy subjects participated in the study of whom 16 were randomly assigned to the experimental group and 13 to the control. The experimental subjects underwent daily qigong training for one month. Blood samples for the quantification of biochemical parameters (total cholesterol, HDL, LDL, triglycerides, phospholipids, GOT, GPT, GGT, urea, creatinine) were taken before and after the training program. As statistical analysis, ANCOVA was performed. RESULTS: Statistically significant differences were found showing that the experimental group had lower serum levels of GOT (glutamic-oxaloacetic transaminase), GPT (glutamic-pyruvic transaminase), and urea and that there was a trend towards significance in GGT (gamma-glutamyltransferase). CONCLUSIONS: This study demonstrates that after practicing qigong for the short period of one month, noteworthy changes in several blood biochemical parameters were induced. While it is tempting to speculate on the relevance and implications of these biochemical variations, further investigation is needed to elucidate the scope of these findings.     

Osteosarcoma of the craniofacial bones. A clinico-pathological study

Thirty-four cases of osteosarcoma involving the craniofacial bones over a period of 19 years were reviewed. They formed 6.2% of osteosarcomas occurring in the skeleton during the same period at the Tata Memorial Hospital. Mean age of occurrence was 30.9% years, with a range of 7 to 61 years. Male preponderance was noted in maxillary tumours (M:F = 2.6:1), while the mandibular tumours occurred with equal frequency in both sexes. The mandible was the bone of origin in 56%, maxilla in 32% and other craniofacial bones in 12% of patients. Histological sub-type did not affect the prognosis. Radical surgery with resection of adequate disease-free margins is the most effective mode of treatment. Morbidity and mortality is due to extensive local recurrence of disease, particularly with maxillary tumours. Metastasis to other organs occurs rarely. No statistically significant difference in survival was observed between tumours of the mandible and maxilla, or between patients above and below 20 years of age.     

Validating the use of two-item measures of pain beliefs and coping strategies for a veteran population.

Previous research has demonstrated that 2-item versions of subscales from the Chronic Pain Coping Inventory, Coping Strategy Questionnaire, and the Survey of Pain Attitudes appear adequately reliable and valid for use in studies with large sample sizes. It was suggested that use of the abbreviated scales might help to expand the testing and application of cognitive-behavioral models of pain to new settings and with new populations where assessment burden might be a key issue. This study explored the utility of these brief scales among veterans in a Veterans Affairs setting. Strong associations were found between the 2-item versions and their respective parent scales. In addition, the 2-item scales were found to be associated with other pain-related measures, supporting their predictive validity. The results of this study replicate previous findings and offer support for the use of the 2-item versions for both screening and research purposes in Veterans Affairs settings with a veteran population. PERSPECTIVE: This article presents the psychometric properties of brief versions of 3 commonly used pain coping and belief questionnaires in a unique population. These measures could be used clinically for initial screening purposes, as well as for treatment monitoring.
