[Purpose] The purpose of this study was to find whether a fast treadmill gait training
speed is effective for the gait training of stroke patients in the early rehabilitation
stage. [Subjects and Methods] Thirty-nine stroke patients were the subjects of our
investigation. They walked on a treadmill with handrail supports at a fast speed (130% of
their comfortable gait speed in the 2nd week). The treadmill gaits of the patients were
recorded using a 3-dimensional analysis system at two and six weeks after their
admissions. Intraclass Correlation Coefficients (ICC) of the temporal and spatial
parameters of the two periods were statistically analyzed. [Results] For all of the
patients, the ICCs of the measured parameters were greater than 0.58. In the case of
patients whose gait speeds of the two periods were close, the ICC units were greater than
0.7. [Conclusion] The fast gait speed training allowed us to expose the patients to a gait
speed that they were expected to acquire at a later stage of their rehabilitation. This
training method was found to be beneficial for the mildly paralyzed patients.Key words: Stroke, Treadmill, Fast speed 相似文献

Objective Clinical outcomes after open heart surgery in patients with liver cirrhosis are not satisfactory. For evaluating hepatic function,
the Child-Pugh classification has been widely used. It has been reported that open heart surgery can be performed safely in
patients with mild liver cirrhosis. In this study, we examined the clinical outcomes after open heart surgery in patients
with liver cirrhosis and evaluated the usefulness of the Child-Pugh classification.
Methods There were 12 liver cirrhosis patients who underwent open heart surgery between January 2002 and December 2006 at our institution.
The severity of cirrhosis was graded according to the Child-Pugh classification. We reviewed clinical outcomes, such as postoperative
mortality and morbidity, and tried to determine the risk factors. Finally, we assessed the usefulness of the Child-Pugh classification.
Results Six patients were classified as having Child class A, and the other six patients were classified as B. The overall mortality
of group A was 50%, and that of group B was 17%. Postoperative major morbidities occurred in half of the patients of Child
class A and in all of the patients of Child class B. Patients who experienced major morbidities had markedly lower levels
of serum cholinesterase (106 ± 46 vs. 199 ± 72 IU/l; P = 0.02) and lower platelet level (7.5 ± 2.9 vs. 11.9 ± 3.6 × 104/μl; P = 0.04).
Conclusion The mortality and morbidity rates were high even in the Child class A patients. The Child classification may be an insufficient
method for evaluating hepatic function. We have to assess other factors, such as the serum cholinesterase level or the platelet
count. 相似文献

[Purpose] The aim of this study was to investigate the recovery process of standing
postural control in hemiplegia after stroke. [Subjects and Methods] Thirty-four inpatients
with hemiparesis after first-onset stroke were included in this study. We measured the
center of pressure fluctuations during quiet standing using a force platform at 2, 4, and
6 weeks after admission. We assessed weight-bearing asymmetry, and velocity and amplitude
of body sway. [Results] Weight-bearing asymmetry diminished in the first 2 weeks of
observation. Velocity of body sway also decreased significantly in the first 2 weeks,
though its amplitude only decreased significantly after 4 weeks of observation.
[Conclusion] Amplitude of body sway requires a longer time for significant improvement
than weight-bearing asymmetry and velocity of body sway. Although the loading function of
the paretic lower limb improved at an early stage, attainment of optimum postural control,
including management of the affected paretic lower limb, requires much time.Key words: Postural balance, Hemiplegia, Recovery of function 相似文献

We examined serum NCC-ST 439 for its significance as a tumor marker of large bowel cancer in 121 patients with primary and 36 with recurrent large bowel cancer. Serum NCC-ST 439 was positive in 27.3 percent of the former and 66.7 percent of the latter. It was false-positive in only 5.6 percent of patients with benign diseases. Positive serum NCC-ST 439 correlated with lymph node and liver metastases. The combination assay for NCC-ST 439, CEA, and CA19-9 was positive in 49.6 percent of the patients with primary tumors and 88.9 percent of those with recurrent tumors; in other words, the diagnostic accuracy improved. The results demonstrated that the determination of serum NCC-ST 439 in large bowel cancer might be useful in cancer staging and that NCC-ST 439, if used in combination with CEA, is particularly useful in diagnosing recurrences because of its improved diagnostic accuracy. 相似文献

Autism spectrum disorder (ASD) (i.e., autism and Asperger syndrome) is a neurodevelopmental disorder, although its etiology is still unclear. Neuroimaging studies have attempted to identify the neurobiological basis of ASD. This article reviews recent progress in ASD research using magnetic resonance imaging (MRI), single photon emission computed tomography (SPECT), and positron emission tomography (PET). MRI studies documented structural and functional abnormalities in cerebella, the frontal lobes, the temporal lobes, and limbic systems of individuals with ASD. SPECT and PET studies suggested that abnormalities of the serotonergic system, in addition to decreased regional cerebral blood flow in the frontal and temporal lobes, are implicated in the pathophysiology of ASD. 相似文献

Enoki Y, Katoh G, Okabe H & Yanagisawa A(2010) Histopathology 56, 384–394 Clinicopathological features and CD57 expression in renal cell carcinoma in acquired cystic disease of the kidneys: with special emphasis on a relation to the duration of haemodialysis, the degree of calcium oxalate deposition, histological type, and possible tumorigenesis Aims: Acquired cystic disease of the kidney (ACDK) in patients undergoing haemodialysis is known to develop into renal cell carcinoma (RCC), but its pathogenesis remains unclear. The aims were to analyse the histological findings of ACDK‐RCC and to determine its histogenesis. Methods and results: Twenty‐nine RCCs in 23 patients with ACDK were classified into three groups according to the duration of haemodialysis and were analysed for histological type, calcium oxalate (Oxa) deposition, and cyst and atypical cyst (AC) formation. Histologically, 21 tumours were ACDK‐RCC and eight were clear cell carcinoma (CCC). The ratio of ACDK‐RCC and the numbers of cysts and ACs increased as the duration of haemodialysis was prolonged. The degrees of intratumoral Oxa deposition and cyst and AC formation of ACDK‐RCCs were higher than those of CCCs (Oxa, P = 0.028; cyst, P < 0.0001; AC, P = 0.0002). Many ACDK‐RCCs (85.7%) and some CCCs (50%) had characteristics of the thin ascending loop of Henle as assessed by CD57 (HNK‐1) expression, which was rarely expressed in the 29 control cases. Conclusions: ACDK‐RCCs reveal characteristics of Henle’s loop, which may be related to their peculiar pathological features, including intratumoral oxalate deposition and cyst and AC formation. 相似文献

Gait disturbance in idiopathic normal pressure hydrocephalus (iNPH) is reminiscent of parkinsonism. Our recent PET study showed reduction in postsynaptic D(2) receptor binding concomitant with a normality of presynaptic dopamine transporter binding. Here, we investigated the plasticity of D(2) receptor in treating iNPH patients with ventriculoperitoneal (VP) shunting using PET with (11)C-raclopride and discuss the contribution of D(2) receptor to the pathophysiology of iNPH. METHODS: Eight iNPH patients participated in this study. After evaluation of their neuropsychologic abilities, all patients underwent 3-dimensional MRI and quantitative PET measurements twice before and 1 mo after VP shunting. MRI-based morphometric analyses were performed to examine postoperative variations of the ventricles. Estimation of binding potential (BP) for (11)C-raclopride was based on Logan plot analysis. Region-of-interest analysis was used to examine changes in (11)C-raclopride BP in the striatum. A 2-tailed paired t test was used for evaluating changes in PET and MRI parameters between conditions, and correlation analysis was used to investigate clinicopathophysiologic relevance (clinical vs. in vivo findings). RESULTS: Clinical evaluation revealed significant recovery in a 5-m back-and-forth navigation test and an affect test and a mild increase in Mini-Mental State Examination scores after VP shunting. Significant postoperative increases in (11)C-raclopride BP were found in the nucleus accumbens and dorsal putamen, and the increases were significantly associated with emotional (Spearman rank r = 0.66, P < 0.05) and navigational improvement (r = 0.72, P < 0.05), respectively. The (11)C-raclopride BP increase in the striaum as a whole correlated significantly with improvement in general cognitive ability. There was a mild ventricular shrinkage after surgery, albeit there was no correlation of its size with clinical and PET parameters. CONCLUSION: Striatal upregulation of D(2) receptor after VP shunting is associated with amelioration of hypokinetic gait disturbance and anhedonic mentation in iNPH patients, indicating that the effect of VP shunting may reside in noninhibition of functionally suppressed D(2) receptor in the striatum. D(2) receptor responsiveness may indicate a mechanism for iNPH pathophysiology. 相似文献

OBJECTIVE: Therapeutic angiogenesis using basic fibroblast growth factor (bFGF) in coronary artery disease has been documented in a number of papers. However, the effectiveness is discrepant among documents. In this study, we evaluated the distribution of bFGF in the rat heart by different administration methods, and investigated the efficacy of slow-released administration of bFGF using biodegradable hydrogel microspheres (bFGF microspheres) in a pig infarction model toward an enhanced coronary bypass surgery. METHODS: Heart failure due to myocardial infarction was induced in rats and pigs. In the rat study, free form of bFGF (central venous injection, intracoronary injection, and intramyocardial administration) and bFGF microspheres (intramyocardial administration) were given 4 weeks later. The remaining radioactivity of bFGF in the hearts was estimated 1, 24, and 72 h later. On the other hand, the pigs were randomized into two groups 4 weeks after myocardial infarction. While the control group (n=8) had gelatin hydrogel microspheres with saline, the FGF group (n=8) received bFGF microspheres in the left ventricular (LV) wall. RESULTS: In the rat study, after intramyocardial administration of bFGF microspheres, more bFGF remained in the rat heart 72 h later compared with the other methods (P<0.0001). In the pig study, 4 weeks after the treatment, the FGF group had smaller LV diastolic diameter (48.7+/-5.3 vs. 56.7+/-5.2 mm, P<0.01) than the control group. LV end-systolic elastance was higher in the FGF group (2.96+/-1.2 vs. 1.06+/-0.3 mmHg/ml, P<0.01). In microscopic examinations, many neovessels were found in and around the scar tissue, and the vascular density in the FGF group was significantly higher (61.5+/-18.3 vs. 153.0+/-29.0/mm2, P<0.01). In addition, the infarcted LV walls were less expanded and more thickened in the FGF group. CONCLUSIONS: Biodegradable hydrogel microspheres with bFGF improved LV function and inhibited LV remodeling by angiogenesis in pigs with chronic myocardial infarction. bFGF microspheres into ischemic myocardium may revascularize small ungraftable vessels and may potentially increase distal run-off when applied in coronary bypass surgery. 相似文献
