Neuroglycan C (NGC) is a transmembrane chondroitin sulfate proteoglycan with an EGF module. We studied the expression of NGC in the human brain, mainly in the hippocampus, and confirmed some observations by conducting experiments using rat brain. In humans, NGC mRNA was expressed exclusively in the brain, especially in the immature brain. The telencephalon, including the hippocampus and neocortex, showed strong mRNA expression. NGC was immunolocalized to neuropils in the hippocampus and neocortex of the adult rat. RT-PCR experiments showed that four splice variants (NGC-I, -II, -III, and -IV) were expressed in the adult human hippocampus. By Western blotting, the expression as proteins of all splice variants except NGC-II was confirmed in the adult rat hippocampus. NGC-IV, which was first found in the present study, had the shortest cytoplasmic domain among the four variants. NGC-IV mRNA was expressed by neurons, but not by astrocytes, in culture prepared from the fetal rat hippocampus, suggesting that NGC-IV plays a role specific to neurons. In addition, the human NGC gene, which is registered as CSPG5, comprised six exons and was approximately 19 kb in size. In exon 2, a single nucleotide polymorphism resulting in Val188Gly in the NGC ectodomain was observed. 相似文献

Introduction
We report four cases of long-gap esophageal atresia (LGEA) treated with thoracoscopic esophagoesophagostomy (TEE) after sequential extrathoracic esophageal elongation (SEEE: Kimura’s technique).Methods
All initially had gastrostomy, then SEEE. The proximal end of the esophagus was introduced into the apex of the thorax under direct vision during TEE.Results
Mean birth weight was 1.9 kg. Mean gestational age was 35.0 weeks (range 30–39); mean age at initial esophagostomy was 43.2 days (range 15–110); SEEE was performed for a mean of 3 times (range 2–4) at mean intervals of 5.3 months (range 2–10), with the upper esophageal segment lengthened by a mean of 2.1 cm each time (range 1.1–3.5). Mean age and weight at TEE were 22.3 months and 9.8 kg, respectively. Gap was initially 4.5 vertebrae (range 4–5). Mean operating time was 9.6 h. TEE was successful in 3; 1 required thoracotomy, then re-anastomosis after 11 months of anastomosis leakage; 2 cases with post-TEE anastomosis leakage were treated conservatively. Postoperatively, all cases required fundoplication and esophageal dilatation (2, 3, 5, 8 times, respectively). At mean follow-up of 3.6 years, 2 eat normally and 2 eat minced food.Conclusions
TEE after SEEE appears to be a feasible option for treating LGEA. 相似文献53.

Purpose The aim of this study was to evaluate retrospectively the toxicity and response, bladder preservation, and survival of patients
with muscle-invasive bladder cancer treated with multimodality therapy consisting of low-dose radiation therapy (RT) and concurrent
intraarterial chemotherapy (IACT).
Methods and materials Between November 1999 and July 2005, a total of 27 consecutive, previously untreated patients with muscle-invasive bladder
cancer underwent transurethral bladder tumor resection followed by concurrent low-dose RT and IACT. Patients who achieved
a complete response (CR) were followed up closely without further therapy, and patients who did not achieve a CR underwent
further treatment.
Results Complete response was achieved in 22 of 27 patients (81%). Of these 22 patients, 7 developed recurrences, and 3 died of their
disease. In five patients who did not achieve CR, one died from bone metastases. The 3-year overall survival rate was 81%,
with a median follow-up time of 27 months; and 22 of 27 patients (81%) with a preserved bladder were tumor-free at the last
follow-up. Three patients (11%) developed grade 3 acute hematological toxicity.
Conclusion Multimodality therapy consisting of low-dose RT and concurrent IACT for muscle-invasive bladder cancer can achieve survival
rates similar to those in patients treated with radical cystectomy, with successful bladder preservation and minimal adverse
effects. 相似文献

Rikkunshito (TJ-43), a herbal medicine consisting of eight herbs, is used to treat chronic dyspepsia. Studies have shown that
TJ-43 improves human gastric emptying. This study investigated the effects of TJ-43 on the clinical symptoms and esophageal
acid exposure in children with symptomatic gastroesophageal reflux (GER). Eight children, aged from 2 months to 15 years (median
age 4 years), were studied. Six of them had neurological impairment. TJ-43 (0.3 g/kg/day) was given orally or via nasogastric
tubes in three divided doses before meals for 7 days. Their symptoms were frequent emesis in four, nausea in two, and hematemesis
and stridor in one each. Twenty-four-hour esophageal pH monitoring was conducted using multichannel pH electrodes located
at the distal esophagus (P1) and 10 cm proximal to P1 (P2). The clinical symptoms and esophageal pH were compared before and
after TJ-43 therapy for 1 week. The frequency of emesis decreased in three patients. Other symptoms, including nausea, hematemesis,
and stridor, were relieved in the remaining patients. Measured at the distal pH electrode, the percentage time of esophageal
pH < 4.0 and the mean duration of reflux decreased significantly (P < 0.05). However, the number of acid reflux per hour did not change significantly, and no pH parameters measured at the proximal
electrode differed significantly. The short-term administration of TJ-43 relieved symptoms and reduced the distal esophageal
acid exposure through improved esophageal acid clearance. 相似文献

This study aimed to elucidate the clinical characteristics of neonates with congenital diaphragmatic hernia (CDH) associated with pneumothorax and evaluate the risk factors for the development of pneumothorax. A retrospective cohort study was conducted in the 15 institutions participating in the Japanese CDH Study Group. A total of 495 neonates with isolated CDH who were born between 2011 and 2018 were analyzed in this study. Among the 495 neonates with isolated CDH, 52 (10.5%) developed pneumothorax. Eighteen (34.6%) patients developed pneumothorax before surgery, while 34 (65.4%) developed pneumothorax after surgery. The log-rank test showed that the cumulative survival rate was significantly lower in patients with pneumothorax than in those without pneumothorax. Univariate analysis revealed significant differences between patients with pneumothorax and those without pneumothorax with regard to the best oxygenation index within 24 h after birth, mean airway pressure (MAP) higher than 16 cmH2O, diaphragmatic defect size, and need for patch closure. Multiple logistic regression analysis indicated that only the MAP was associated with an increased risk of pneumothorax. The cumulative survival rate was significantly lower in isolated CDH patients with pneumothorax than in those without pneumothorax. A higher MAP was a risk factor for pneumothorax in CDH patients. 相似文献

Six rheumatoid articular cartilage specimens, which appeared grossly normal and were shown to be free of pannus when examined under the light microscope, were examined electron microscopically. For comparison, normal-appearing cartilage specimens from 2 patients with meniscus injury and 2 with degenerative joint disease (DJD) were also examined. In all cases the normal-appearing joint surface of rheumatoid cartilage was abnormal. Amorphous-appearing material was present to a depth varying between 6 and 25 m̈m. Some of this material had the appearance of fibrin deposited at the cartilage surface, but much appeared to represent breakdown products of the cartilage matrix, i.e. degraded collagen and proteoglycan. DJD cartilage did not show similar changes. The findings suggest that the surface of rheumatoid articular cartilage, even when grossly normal in appearance, is degraded by enzymes either present in the synovial fluid or released by polymorphonuclear cells in close contact with the cartilage surface. 相似文献

Objective
To present the efficacy of Japanese-traditional medicine (Kampo) for a case with vascular malformation.Methods
A case study and literature review.Patient
A 62-year-old female presented with dysphagia and spitting blood. Esophagogastroduodenoscopy showed a longitudinal lobulated and septated mass in the posterior pharynx. On MR imaging, the mass showed hyperintensity on T2-weighted images and heterogeneous enhancement on Gadlinium-enhanced T1-weighted images, suggestive of a low-flow vascular malformation.Intervention
According to the Kampo diagnosis, kamisyouyousan and ninjinyoueito were prescribed to this patient. The effect of Kampo medicine was evaluated with improvement of her symptoms and volumetry of MRI findings.Result
The longitudinal pharyngeal mass was markedly decreased and her symptoms disappeared after 2 years of Kampo administration.Conclusions
Kampo medicine can be a novel alternative therapy for VM. 相似文献59.

Purpose
This study was aimed to evaluate the influence of timing of surgery on patient outcomes, and to clarify appropriate timing of surgery in neonates with congenital diaphragmatic hernia (CDH).Methods
A total of 477 neonates with isolated CDH were included. Patients were classified into two groups by timing of surgery: early repair (ER) (≤48 h) and delayed repair (DR) (>48 h). The primary outcome was 90-day survival, with treatment duration (ventilation, oxygen, and hospitalization) being a secondary outcome. To adjust for disease severity, patients were stratified into three severities by Apgar score 1 min (“mild” 8–10, “moderate” 4–7, and “severe” 0–3), and outcomes were compared between ER and DR within each severity.Results
Although 90-day survival was significantly different among the three severities (“mild” 97%, “moderate” 89%, and “severe” 76%, p = 0.002), there were no differences in 90-day survival between DR and ER within each severity. In “mild”, there were no differences in treatment duration between ER and DR. In “moderate”, treatment duration was shorter in ER than DR (ventilation 11 vs. 16 days, oxygen 15 vs. 20 days, and hospitalization 34 vs. 48 days). In “severe”, treatment duration was shorter in ER than DR, while the best OI was higher in DR than ER.Conclusions
Timing of CDH repair seems to have no influence on 90-day survival regardless of disease severity. Patients with moderate severity may benefit from the early repair by reducing treatment duration.60.
