The objective of this study is to compare the effects of three different anesthetic combinations on the electroretinogram
in the same animals under similar laboratory conditions. Thiopental–isoflurane (TI), medetomidine–ketamine (MK), and xylazine–ketamine
(XK) were used on each of 12 healthy miniature schnauzer dogs (MS) with a period of at least 3 weeks in between subsequent
anesthesia protocols, using the Dog Standard Protocol. The scotopic ERGs consisted of scotopic low stimulus strength (S) responses
designated S1, S2, S3, S4, and S5, at 1, 5, 10, 15, and 20 min after dark adaptation, respectively, and scotopic standard
stimulus strength (S-ST) responses. The photopic ERGs consisted of a photopic single flash (P) response and 31 Hz flicker
(P-FL) responses. For S-ST (2.5 cd s/m2), the amplitude of the a-wave using TI was significantly lower than that using MK (adjusted P = 0.05) and XK (adjusted P = 0.03), and the implicit time of the a-wave was significantly shorter than that using MK (adjusted P = 0.04). For P (2.5 cd s/m2), the amplitude of the b-wave using XK was significantly higher than that using MK (adjusted P = 0.01). The implicit times of the b-wave using TI was significantly longer and shorter than that of MK for S1, S2 and P-FL
and for S4 and S-ST, respectively, and than that of XK for S2 and P-FL and for S5 and S-ST, respectively. The results of the
present study showed that TI affected both the amplitude and the implicit time of the a-wave for S-ST and the implicit time
of the b-wave relatively more so than was the case when using XK or MK. Therefore, it appears that either XK or MK could be
advantageous to use rather than TI for clinical studies. 相似文献

Conclusion We would like to stress that we do not necessarily consider AC for SPECT MPI to be unfeasible or unworthy of scientific pursuit;
indeed, a great deal of creative scientific effort has been poured into this area of investigation over the past 3 decades,
and much of it has contributed to a better understanding of the physics, as well as the clinical aspects, of our field. However,
the great variety of available AC hardware and software “flavors,” the historical pattern of commercial release of insufficiently
validated AC implementations, and the increasingly clouded health care reimbursement horizon may have created an environment
where the envisioned users of the technology have been desensitized and discouraged from expecting it to ever come to fruition
in a standardized, validated, and costeffective form.
It has been reported as recently as 2005 that the “entire base of SPECT cameras has only 5% of systems with attenuation correction.”8
Perhaps the reports of AC’s demise are exaggerated, but it certainly seems as if the people have spoken and, after readying
themselves for the wolf one too many times, have come to the conclusion that “the future (of AC) ain’t what it used to be”
. . .at least not yet. 相似文献

目的:探讨平面导板矫治重度深覆[牙合]患者的作用机制及临床作用要点。方法:对18名生长发育期的重度深覆[牙合]患者,用平面导板来打开咬合,并对咬合打开前后的硬软组织变化进行分析。结果:①上下后牙及牙槽高度均增加,下后牙及牙槽高度的增加值大于上后牙及牙槽高度的增加值,而对前牙及牙槽高度的影响无统计学差异;②上下颌骨在水平方向上无改变,但下颌平面角与下面高/全面高治疗后较治疗前增大,后面高/前面高治疗后较治疗前减小;③覆[牙合]减小,Spee氏曲线得到整平;④松弛的下唇肌肉得到紧张,从而改善了侧貌外形。结论:平面导板使覆[牙合]减小主要是后牙及后牙齿槽突高度增加的结果,对生长发育期的低角重度深覆[牙合]患者治疗效果较好。 相似文献

Survival after resection of colorectal liver metastases has traditionally been associated with clinicopathologic factors.
We sought to investigate whether echogenicity of colorectal liver metastasis as assessed by intraoperative ultrasound (IOUS)
was a prognostic factor after hepatic resection. Prospective data on tumor IOUS appearance were collected in 84 patients who
underwent hepatic resection for colorectal liver metastasis. Images were digitally recorded, blindly reviewed, and scored
for echogenicity (hypo-, iso-, or hyperechoic). The median tumor number was 1 and the median tumor size was 5.0 cm. At the
time of surgery, the IOUS appearance of the colorectal liver metastases were hypoechoic in 35 (41.7%) patients, isoechoic
in 37 (44.0%) patients, and hyperechoic in 12 (14.3%) patients. Traditional clinicopathologic prognostic factors were similarly
distributed among the three echogenicity groups (all p > 0.05). Patients with a hypoechoic lesion had a significantly shorter median survival (30.2 months) compared with patients
who had either an isoechoic (53.2 months) or hyperechoic (42.3 months) lesion (p = 0.005). The 5-year survival after hepatic resection of colorectal liver metastasis was also associated with the echogenic
appearance of the lesion (hypoechoic 14.4 vs isoechoic 37.4 vs hyperechoic 46.2%) (p < 0.05). Intraoperative ultrasound echogenicity should be considered a prognostic factor after hepatic resection of metastatic
colorectal cancer.

Management of upper gastrointestinal bleeding because of erosion of vessels by esophageal cancer may be challenging. We present
herein the angiographic images of a 49-year-old patient who was admitted with massive bleeding from a tumor-eroded inferior
thyroid artery. Attempts to control the bleeding by means of flexible endoscopy and insertion of a Sengstaken–Blakemore tube
had failed. The diagnosis was impressively demonstrated by multislice computed tomography with intravenous contrast in the
arterial phase and multiplanar reconstructions (computed tomography angiography) and by digital subtraction angiography. The
bleeding was successfully treated with superselective catheterization and coiling of the eroded vessel. 相似文献

Cooking processes that gelatinize granules or disrupt structure might increase the glucose and insulin responses because a disruption of the structure of starch by gelatinization increases its availability for digestion and absorption in the small intestine. We hypothesized that the uncooked form of rice, which has a relatively low degree of gelatinization even though in powder form, would result in lower metabolic glucose and insulin responses compared with cooked rice (CR). To assess the effects of the gelatinization of rice on metabolic response of glucose and insulin, we investigated the glucose and insulin responses to 3 rice meals of different gelatinization degree in female college students (n = 12): CR (76.9% gelatinized), uncooked rice powder (UP; 3.5% gelatinized), and uncooked freeze-dried rice powder (UFP; 5.4% gelatinized). Uncooked rice powders (UP and UFP) induced lower glucose and insulin responses compared with CR. The relatively low gelatinization degree of UPs resulted in low metabolic responses in terms of the glycemic index (CR: 72.4% vs UP: 49.7%, UFP: 59.8%) and insulin index (CR: 94.8% vs UP: 74.4%, UFP: 68.0%). In summary, UPs that were less gelatinized than CR induced low postprandial glucose and insulin responses. 相似文献

Abstract
Background: Primary shoulder hemiarthroplasty is an established treatment modality for complex fractures of the proximal humerus. Long-term
functional outcome is often disappointing. However, little is known about social implications particularly in the elderly.
Methods: A single-institution case series of consecutive geriatric patients (age > 70 years) treated with shoulder hemiarthroplasty
for complex fractures of the proximal humerus between 1994 and 1997 was analysed. Postoperative morbidity, long-term function,
radiological outcome and social implications were evaluated.
Results: Seventy-seven patients fulfilled the study criteria. Median age at the time of operation was 80 years (range 70–93 years).
Systemic and local postoperative complications were observed in 8% including 2 patients (3%) with revision surgery. Postoperative
mortality was 1%. Forty-eight patients (62%) were available for follow-up (median 49 months, range 25–80 months), 22 (29%)
died from causes unrelated to hemiarthroplasty before follow-up and 7 patients (9%) did not attend follow-up examination.
Median Constant-Murley score was 41 points (range 17–77 points). Long-term results concerning pain were satisfying. The Oxford
shoulder score ranged from 14 to 40 (median 30). Forty-one patients (85%) still lived in their original environment and managed
their daily life independently despite poor shoulder function. Four patients (8%) lived in a retirement home and 3 (6%) in
a nursery home. Eighty percent of our patients were still able to use public transportation, do the daily shopping and wash
their whole body by themselves.
Conclusion: Most patients managed their daily life independently despite poor shoulder function. 相似文献
