Maxillary first molar with two palatal canals is rare. Clinicians should be aware of the normal anatomy of root canal system and vigilant about the possible existence of canal variation. A patient with acute episode of chronic pulpitis of 26, as presented by the case report, was examined to have four canals, which were the mesial buccal canal, the distal buccal canal, the mesial palatal canal and the distal palatal canal. When suspecting the existence of canal variation, clinicians should carefully explore the pulpal floor, further by changing the X-ray projection angle to confirm the existence of variation and prevent the missed canals, all of which are necessary for a successful root canal therapy.

AIM: To investigate the MSCT imaging features of intestinal metastases of gastric cancer. METHODS: From August 2011 to December 2014, 96 patients with intestinal metastasis of gastric cancer by X-ray underwent plain and contrast-enhanced abdominal CT scans at our hospital, and 68 of them underwent a second CT scan. The changes in intestinal wall and peritoneal cavity were observed. RESULTS: The changes in the bowel wall in patients with intestinal metastases of gastric cancer were mainly rectal and colonic wall thickening and annular enhancement. Plain CT scans showed that 37.5% of patients with intestinal metastases of gastric cancer had abdominal effusion, which was mainly located in the pelvic cavity. A second plain CT scan showed that more than 50% of patients became sicker in patients with involvement of the colon or rectum. CONCLUSION: Intestinal metastases of gastric cancer can cause bowel wall thickening and enhancement. Abdominal effusion, which is mainly located in the pelvic cavity, is an important sign of intestinal metastases of gastric cancer. X-ray double contrast barium enema may show negative results, which can be detected by CT earlier. © 2016 Baishideng Publishing Group Inc. All rights reserved.

AIM: To investigate the effect of arginine-rich enteral nutrition support on the prognosis of patients with severe craniocerebral injury, and to provide scientific and effective nutritional support for patients with severe brain injury. METHODS: A retrospective analysis was performed of clinical data of 309 patients with severe craniocerebral injury treated from July 2014 to July 2015 at our hospital. According to postoperative enteral nutrition the patients received, these patients were divided into a standard nutrition group (EN group) and an arginine enhanced group (AEN group). On postoperative day 7, nutritional indicators, immunological indexes, postoperative complications and prognosis were compared between the two groups. RESULTS: Preoperative total protein content, albumin, hemoglobin and albumin levels showed no significant differences between the two groups (P > 0.05). On day 7 after intervention total protein content showed no statistical significance between the two groups (P > 0.05), but albumin, hemoglobin, and prealbumin levels were significantly higher in the AEN group than in the EN group (P < 0.05). There were no significant differences in white blood cells or the proportion of CD8+ cells between the two groups (P > 0.05), but total lymphocyte content, proportion of CD4+ cells, and CD4+/CD8+ ratio were significantly higher in the AEN group than in the EN group (P < 0.05). There were no significant differences in the rates of wound infection or respiratory tract infection between the two groups (P > 0.05), but the total number of cases of urinary tract infections and the proportion of postoperative complications were significantly lower in the AEN group than in the EN group (P < 0.05). Time to first defecation and hospital stay were significantly shorter in the AEN group than in the EN group (P < 0.05). CONCLUSION: Enteral nutritional support can not only effectively improve the nutritional status and immune function of patients with severe craniocerebral injury, but also effectively reduce the incidence of complications and shorten the length of hospital stay. © 2015 Baishideng Publishing Group Inc.

Background: The growth and development of the posterior silk gland and the biosynthesis of the silk core protein at the fifth larval instar stage of Bombyx mori are of paramount importance for silk production.Results: Here, aided by next-generation sequencing and microarry assay, we profile 1,229 microRNAs (miRNAs), including 728 novel miRNAs and 110 miRNA/miRNA* duplexes, of the posterior silk gland at the fifth larval instar. Target gene prediction yields 14,222 unique target genes from 1,195 miRNAs. Functional categorization classifies the targets into complex pathways that include both cellular and metabolic processes, especially protein synthesis and processing.Conclusion: The enrichment of target genes in the ribosome-related pathway indicates that miRNAs may directly regulate translation. Our findings pave a way for further functional elucidation of these miRNAs and their targets in silk production. © 2014 Li et al.; licensee BioMed Central Ltd.

AIM: To investigate the therapeutic effects of omeprazole in reflux esophagitis patients with foreign body sensation in the throat as the main clinical manifestation.RESULTS: After treatment, the percentages of patients with pain (87.8% vs 12.2%), regurgitation (62.2% vs 10.5%), bitter taste in the mouth (52.9% vs 6.4%), foreign body sensation in the throat (13.5% vs 1.2%), dysphagia (16.9% vs 2.3%), nausea and vomiting (34.3% vs 4.1%), and chest distress (17.4% vs 1.7%) in the observation group and those in the control group (21.3% vs 4.0%, 38.7% vs 9.3%, 22.7% vs 2.7%, 100% vs 12.0%, 85.3% vs 8.0%, 68.0% vs 6.7%, 18.7% vs 1.3%) were significantly reduced (P < 0.05). The total effective rate was 75.6% in the treatment group and 80.0% in the control group, and there was no significant difference between the two groups (P > 0.05).METHODS: The patients with reflux esophagitis treated at our hospital from January 2012 to June 2014 were divided into two groups: an observation group and a control group (n = 172). The observation group comprised 75 patients with foreign body sensation in the throat as the main clinical manifestation, while the control group comprised 172 patients in whom foreign body sensation in the throat was not as the main clinical manifestation. Both groups accepted omeprazole treatment. The clinical efficacy, endoscopic classification changes, and improvement of clinical symptoms were compared between before and after treatment and between the two groups.CONCLUSION: Omeprazole can achieve comparable clinical effects between reflux esophagitis patients with pharyngeal foreign body sensation as the main clinical manifestation and those in whom foreign body sensation in the throat is not as the main clinical manifestation. © 2014 Baishideng Publishing Group Inc.
