ObjectiveTo know the fundamental status of painless digestive endoscopy in China. MethodsA 23-item survey including multiple choices and fill-in-the-blank questions on 3 pages was performed on anesthesiologists in China excluding Taiwan, Macao and Hong Kong on www.xqnmz.com and www.dxy.cn/bbs from November 1 to December 31, 2013, among which 5 questions were on personal details, 9 on hospital and department, and 9 on clinic details. The results about the basic facts, risk factors of anesthesia and drug use and monitoring of painless digestive endoscopy in China were analyzed. ResultsA total of 726 questionnaires were collected, among which 667 (91.87%) were considered valid. Interviewed hospitals included hospitals from 31 provinces, municipalities and autonomous regions excluding Taiwan, Macao and Hong Kong. Thirty questionnaires were from the first-grade hospitals (4.5%), 292 from the second-grade (43.78%), and 345 from the third-grade (51.72%). And 69.12% of the questionnaires showed these hospitals could only carry out painless gastroscopy and/or colonoscopy, while 80.81% showed the number of the mean painless endoscopy cases was 0-30 per day; 47.23% of the respondents working in digestive endoscopy center had to complete the anesthesia procedure alone, and 35.83% of the respondents illustrated their digestive endoscopy centers had established the post anesthesia care unit; 62.97% were equipped with anesthesia apparatus or ventilator; 89.96% were equipped with tracheal intubation tool; and 21.44% were equipped with defibrillator. Among them, 25.79% did not prepare rescue medicines regularly in digestive endoscopy center. Propofol was the most frequently used anesthetic, and composited fentanyl was at the highest use rate for gastrointestinal endoscopy. Respondents who used electrocardiogram, non-invasive blood pressure and pulse oxygen saturation the least to monitor during painless gastroscopy and colonoscopy took up 43.48% and 46.08% respectively. ConclusionPainless digestive endoscopy needs further development and standardization with the regulation of related guidelines and standardized residents training.
ObjectiveTo explore the relationship between severity of gastrointestinal symptoms and psychological stress after the earthquake. MethodsThe sample was teachers from Baoxing county which was most affected by the earthquake. Post-traumatic stress disorder checklist civilian version (PCL-C) scale was used to assess the symptoms of psychological stress at 2-3 weeks, 2-3 months, and 6 months after the earthquake, and gastrointestinal symptoms were evaluated using three questions of patient health questionare (PHQ)-15 at 2-3 months and 6 months after the earthquake. Spearman rank correlation was used to explore the dynamic relationship between the symptoms of psychological stress evaluated at the three waves and gastrointestinal symptoms evaluated at 2-3 months and 6 months after the earthquake. ResultsPrevalence rates of gastrointestinal symptoms in teachers were 6.7% and 4.7% for stomach and abdominal pain, 6.7% and 5.6% for constipation and diarrhea, and 9.1% and 8.1% for nausea and gastrointestinal flatulence or dyspepsia at 2-3 months and 6 months after the earthquake. The relationships between three gastrointestinal symptoms evaluated at 2-3 months and 6 months after the earthquake and psychological stress symptoms evaluated at the three waves were all significant (all P<0.05). ConclusionGastrointestinal symptoms are common among the teachers. The association between psychological stress symptoms and severity of gastrointestinal symptoms at the same point after the earthquake is most strong, and psychological stress symptoms in the early period can predict the severity of subsequent gastrointestinal symptoms, and gastrointestinal symptoms in the early period can predict symptoms of subsequent psychological stress.
Objective o explore the effect and mechanisms of transmembrane 4 super family (TM4SF) in digestive system cancer. Methods Articles were reviewed to discuss the biological characteristics of TM4SF in digestive system cancer. Results TM4SF played an important role in migration and invasion of digestive system cancer, including pancreatic cancer, gastric cancer, colorectal cancer, hepatic cancer, esophageal cancer, and so on. TM4SF modulated the cell biological activities by microdomains which were fixed on cell membrane, such as adhesion, migration, invasion, and proliferation. Conclusion TM4SF may be used to predict the metastasis and prognosis of digestive system cancer and may be the targets of therapy of it in the future.
ObjectiveTo understand the latest research progress of long noncoding RNAs (lncRNAs) in occurrence and development mechanisms of common digestive system neoplasms. MethodLiteratures about regulated occurrence and development mechanisms of digestive system neoplasms by lncRNA were reviewed according to the results searched from PubMed. ResultsThere were three main function modes (decoy, guide, and scaffold) of the lncRNAs, which could regulate proliferation, apoptosis, invasion, and metastasis of the digestive system neoplasms, such as gastrointestinal cancer, liver cancer, and pancreatic cancer through the mechanisms of the epigenetic regulation, transcription regulation, and posttranscription regulation. ConclusionsThe functions and tumorigenic mechanisms of the most lncRNAs are not entirely clear. The functions of lncRNAs played in the digestive system neoplasms needs to be understood, which might contribute to new tumor biomarker detection and effective treatment strategies.
ObjectiveTo systematically review the association between angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) therapy and digestive system neoplasms.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, VIP and CBM databases were searched from inception to February 2017 to collect studies about ACEIs/ARBs therapy and risk of digestive system neoplasms or survival of digestive system neoplasms patients. Two reviewers independently screened the literature, extracted the data and evaluated the risk of bias of included studies, then meta-analysis was performed using Stata 12.0 software.ResultsA total of 21 articles including 32 studies were included. The results of meta-analysis showed that ACEIs/ARBs therapy could reduce the risk of colorectal cancer (OR=0.92, 95%CI 0.86 to 0.99, P=0.023), but there were no relationships between ACEIs/ARBs therapy and the risk of liver cancer or gastric cancer. ACEIs/ARBs therapy could improve the survival of colorectal cancer patients (HR=0.79, 95%CI 0.63 to 0.98, P=0.031), but there was no association between ACEIs/ARBs therapy and the survival of pancreatic cancer patients (HR=0.75, 95%CI 0.50 to 1.13, P=0.165).ConclusionACEIs/ARBs therapy may reduce the risk of colorectal cancer, as well as improve the survival of colorectal cancer patients, but there are no significant relationships between ACEIs/ARBs therapy and the risk or the survival of other digestive system neoplasms, such as liver cancer, gastric cancer and pancreatic cancer. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
Objective To have more insight into roles of growth differentiation factor-15 (GDF15) in digestive tumor. Method The basic and clinical studies on the GDF15 in the digestive tumors published were searched in the databases for summarizing the latest advances on this issue. Results The GDF15, a novel member of transforming growth factor-β superfamily, played the diverse roles in the progress of the various diseases. The increasing number of evidence indicated that the GDF15 was associated with the diagnosis and prognostication of the digestive tumors, eg: colorectal cancer, hepatocellular carcinoma, pancreatic adenocarcinoma, and might serve as a potential biomarker and therapeutic target for the multiple digestive tumors. Conclusions Current basic and clinical studies provide some evidences that GDF15 plays a role in digestive tumors. Further studies are needed to elucidate its roles and molecular mechanisms in different stages of diseases.
