Lateral and ventral columns of the spinal cord are responsible for pyramidal tract signs, and insidious ongoing inflammation related to chronic toluene intoxication in the central nervous system is predicted to underlie the pathogenesis.BackgroundPortal venous gas (PVG) is considered a rare finding with a grave prognosis. The most common and critical underlying pathology of PVG is bowel necrosis. However, bowel necrosis is sometimes difficult to properly diagnose. We retrospectively analyzed data of patients that contributed to the decision to perform emergency operation and bowel resection.MethodsBetween 2009 and 2019, 25 consecutive adult patients with PVG were retrospectively identified. Patients were divided into the Operation and Non-operation groups. The Operation group was further subdivided into the Bowel resection and Non-resection groups. Clinical, laboratory and radiographic parameters were analyzed.ResultsConservative management was successful for 32% (8/25) of patients (Non-operation group mortality 0%). Sixty-eight percent (17/25) were surgically managed (Operation group mortality 35.3%). In the Operation group, 52.9% (9/17) underwent bowel resection (Bowel resection group mortality 55.6%); however, bowel resection was unnecessary in 47.1% (8/17) of cases (Non-resection group mortality 12.5%). A univariate analysis revealed significant differences in GCS, APACHE II, abdominal distention, CRP, lactate, and CT findings of dilatation of bowel, pneumatosis intestinalis, and attenuation of contrast effect of the bowel wall between the Operation and Non-operation groups. However, there were no significant differences between the Bowel resection and Non-resection groups, with the exception of GCS.ConclusionsClinical, laboratory and radiographic parameters can inform decisions on conservative management. However, 47.1% of patients who underwent surgery for suspected bowel necrosis did not require bowel resection, suggesting that this approach alone may not be sufficient to avoid non-therapeutic laparotomy. A new approach should therefore be developed to improve this situation.BACKGROUND The nuclear receptor genes, including estrogen receptor β (ERβ), contain non-conventional internal and terminal exons, and alternative choice of the exons yields multiple mRNA and protein variants with unique structures and functions. However, the genomic structure of the intronic and 3'-downstream regions of the human ERβ gene and the presence of novel ERβ variants with non-conventional sequences have not been re-examined for approximately two decades. Therefore, we attempted to re-characterize the structure of the human ERβ gene and identify novel non-conventional exons and distinct splice variants. METHODS Rapid amplification of cDNA 3'-end and RT-PCR cloning were performed to isolate human ERβ mRNA variants from the testis. The identified cDNA sequences were mapped on the human genome assembly. Expression profiles of the variants were assessed by RT-PCR analysis. RESULTS We cloned multiple ERβ mRNA variants with novel nucleotide sequences from the testis and identified several alternative splice sites, 3'-elongation of conventional coding exons, and novel terminal exons in the human ERβ gene. The variants encode C-terminally truncated ERβ proteins termed ERβ6, ERβ7, ERβEx. 4L, and ERβEx. 6L. Furthermore, we identified the presence of exon 7-defective forms of ERβ2/βcx, ERβ4, ERβ6, and ERβ7. Subsequently, we determined distinct expression patterns of the variants in human peripheral organs and brain subregions. CONCLUSION This study elucidated the complicated genomic organization and splicing patterns of the human ERβ gene that contribute to the distinct heterogeneity of human ERβ mRNAs and proteins.BACKGROUND Peripheral blood stem cell (PBSC) collection places a burden on the patient and ideally should be completed in a single procedure. Consequently, a convenient predictive factor is needed for clinical use. METHODS This retrospective study included 72 patients who underwent autologous PBSC collection. A median volume of 3.9×106 CD34-positive cells/kg (range 0.3-47.4×106 cells/kg) was collected on the first day. We defined failure as an inability to collect 2.0×106 cells/kg on the first day. Patients were classified into failure (n = 25, 34.7%) and success groups (n = 47, 65.3%), and their clinical backgrounds were analyzed. selleck chemical RESULTS The success group included a significantly larger number of cases in which a differential white blood cell count of the peripheral blood on the day of PBSC collection detected promyelocytes (n = 34, 72.3% vs. failure group n = 11, 44.0%; P＝0.008). Sixty-two patients underwent autologous PBSC transplantation with a median of 5.6×106 transplanted cells/μL (range 1.60-47.4×106 cells/μL). Among transplanted patients, no significant differences were observed between the success and failure groups in terms of the intervals until neutrophil, platelet, and red blood cell engraftment. CONCLUSION The presence of promyelocytes in peripheral blood may be a useful indicator of the optimal timing for single-step PBSC collection.BACKGROUND The reliability of methods to identify the circumferential position of small lower esophageal lesions remains unknown. We prospectively investigated a new method for distinctively presenting lesion positions as times on a clock face. METHODS Eighty-seven patients were consecutively examined by endoscopy. After observing the esophagus, an endoscope was inserted into the stomach and fixed, setting the greater curvature folds at the upper gastric corpus horizontal on the endoscope monitor display. The scope was retrogressed into the lower esophagus. At this point, the right wall at the hiatus may be at the 3 o' clock position (R-line). The scope was then retrogressed from the gastric angle to the cardia along the center of the lesser curvature in the retroflexed view to obtain the LC-line (the center of the lesser curvature at the cardia). The LC-line in the esophageal hiatus in the frontal view was then identified. The angle between the R- and LC-lines (R-LC) was measured. RESULTS Seventy-seven patients were examined after excluding 7 with >2-cm hernias and 3 with esophageal stenosis.
