Adolescent idiopathic scoliosis (AIS) is a spinal deformity most commonly arising in apparently healthy girls around puberty. AIS has a strong genetic predisposition. Several genetic associations between AIS and single nucleotide polymorphisms (SNPs) have been reported; common SNPs in the genes for matrilin 1 (MATN1), melatonin receptor 1B (MTNR1B), tryptophan hydroxylase 1 (TPH1), and insulin‐like growth factor 1 (IGF1) are reported to be associated with AIS in Chinese. However, these associations have not been replicated so far. To confirm the associations, we compared these SNPs with AIS predisposition and curve severity in a population of Japanese females consisting of 798 AIS patients and 1,239 controls. All the subjects were genotyped using the PCR‐based Invader assay. We found no association of any of the SNPs with AIS predisposition or curve severity. Considering the statistical power and sample size of the present study, we concluded that these SNPs are not associated with either AIS predisposition or curve severity in Japanese. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Purpose: To compare efficacy and safety of dual docetaxel/nedaplatin treatment versus docetaxel alone as second-line chemotherapy for advanced esophageal cancer.Methods: In all, 36 patients with metastatic and/or recurrent esophagus squamous cell carcinoma resistant to first-line chemotherapy (fluorouracil/cisplatin) were recruited from 2011 to 2018 and randomized into two groups. Treatment response and survival were compared between the docetaxel/nedaplatin (60/80 mg/m2/day) group and docetaxel (70 mg/m2/day) group. Treatment was repeated every 3 weeks until tumor progression. Patients were followed up until March 2019 or death.Results: The frequency of Grade 3 or higher adverse events in the docetaxel/nedaplatin group (58.8%) was higher compared with the docetaxel group (26.3%) (P = 0.090). We found a treatment response rate of 52.9% and 36.8% and a median survival of 8.9 and 7.0 months in the docetaxel/nedaplatin-treated and docetaxel-treated group, respectively (P = 0.544).Conclusion: No significant survival advantage was found for docetaxel/nedaplatin-treated patients, although there was an increased frequency of high-grade adverse events compared to docetaxel-treated patients. Because of the limited cohort size, a Phase III study based on our findings is not warranted to assess the clinical impact of docetaxel/nedaplatin treatment. This trial is registered with the University Hospital Medical Information Network (UMIN 000005877). 相似文献

Background and aims
In two Japanese infants with neonatal cholestasis, 3-oxo-Δ4-steroid 5β-reductase deficiency was diagnosed based on mutations of the SRD5B1 gene. Unusual bile acids such as elevated 3-oxo-Δ4 bile acids were detected in their serum and urine by gas chromatography–mass spectrometry. We studied effects of oral chenodeoxycholic acid treatment.Patients and methods
SRD5B1 gene analysis used peripheral lymphocyte genomic DNA. Diagnosis and treatment of these two patients were investigated retrospectively and prospectively investigated.Results
With respect to SRD5B1, one patient was heterozygous (R266Q, a novel mutation) while the other was a compound heterozygote (G223E/R261C). Chenodeoxycholic acid treatment was effective in improving liver function and decreasing unusual bile acids such as 7α-hydroxy- and 7α,12α-dihydroxy-3-oxo-4-cholen-24-oic acids in serum and urine.Conclusion
Primary bile acid treatment using chenodeoxycholic acid was effective for these patients treated in early infancy before the late stage of chronic cholestatic liver dysfunction. 相似文献87.

The patient is a 20-year-old man with glycogen storage disease type I (GSD-type I). In his teens, multiple focal hepatic masses
were detected on abdominal ultrasonography (US), which were diagnosed as multiple hepatocellular adenomas from the imaging.
During follow-up, these masses had shown intermittent growth in size. In the evaluation of Gd-EOB-DTPA (gadolinium-ethoxybenzyl-diethylenetriamine
penta-acetic acid) MR imaging, these masses showed various signal intensities from hypo- to hyperintense during the hepatocyte-specific
phase. Intermittent growth and elevation of serum PIVKA-II levels indicate the potential for malignant transformation, so
the patient underwent partial hepatectomy. The resected masses were all consistent with benign hepatocellular adenomas histopathologically. 相似文献

Background and Aims
Chemokine CXC ligand 13 (CXCL13) and CXC receptor type 5 (CXCR5) are constitutively expressed in tertiary lymphoid follicles where the CXCL13/CXCR5 system regulates B lymphocytes homing. In this study, we sought to examine CXCL13 expression in the H. pylori-infected and -uninfected gastric mucosa and to elucidate the implication in the pathogenesis of HAG in humans.Methods
Using endoscopic biopsies taken from the gastric antrum of 29 subjects infected with Helicobacter pylori and 22 uninfected subjects, mucosal CXCL13 mRNA and protein levels were measured by real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively.Results
The CXCL13 expression levels were significantly more elevated in H. pylori-positive patients than uninfected ones. The CXCL13 expression levels correlated with the degree of chronic gastritis and bacterial colonization. Immunohistochemistry and in vitro infection assay showed that CXCL13 was not produced by the gastric epithelium, but the α-smooth muscle antigen expressing mesenchymal cells were the possible source of CXCL13 within H. pylori-infected gastric mucosa. CXCR5 immunostaining was seen in the CD20-positive lymphoid aggregates.Conclusions
The enhanced induction of CXCL13 may be involved in the pathogenesis of H. pylori-associated gastritis.90.
