ObjectiveTo explore the trend and hotspots of research in the field of peripherally inserted central catheter (PICC), so as to provide a reference for clinical nursing and nursing research in the field of vascular access in China.MethodsAll PICC-related articles from 1806 to November 22nd, 2018 were searched in the Foreign Medical Retrieval System. The publication amount, year of publication, language, country, journals and impact factor, high-yield authors and high-frequent medical subject headings (MeSH) of the PICC-related articles were analyzed by using frequency, cumulative frequency, and constituent ratio.ResultsA total of 1 550 articles were included. They were published in 586 journals, of which 393 were included in Science Citation Index. English was the dominant publication language, and the top high-yield country was the United States. The top 16 high-yield authors published 199 articles, the top 3 of whom all had published co-operative papers, ranging from 1 article to 19 articles. The top 3 high-frequent MeSHs were “Catheters, Indwelling” “Catheterization, Central Venous” “Central Venous Catheter”.ConclusionsPICC has become a hotspot in clinical research, and the publication amount of relative literature has increased rapidly since 2000. Chinese scholars should improve their English and carry out multi-center cooperative research to improve the quality of PICC-related literature.
ObjectiveTo systematically review the association between insomnia and the risk of hypertension. MethodsThe EMbase, PubMed, The Cochrane Library, VIP, WanFang Data and CNKI databases were electronically searched to collect cohort studies on the association between insomnia and hypertension from inception to October 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 13.0 software. ResultsA total of 20 cohort studies involving 607 409 participants were included. The results of meta-analysis showed that insomnia increased the risk of hypertension (RR=1.24, 95%CI 1.15 to 1.34, P<0.000 1). Subgroup analysis showed that insomnia increased the risk of hypertension in North American, European and Oceanian population, but not in Asian population. The difficulty falling asleep, difficulty maintaining sleep and early awakening all increased the risk of hypertension. ConclusionCurrent evidence suggests that insomnia increases the risk of hypertension.
ObjectiveTo summarize the clinical experience on primary suture after common bile duct exploration and to investigate its clinical indications and curative effects. MethodsThe clinical data of 137 patients underwent primary closure of common bile duct between February 2006 and June 2010 were analyzed retrospectively. ResultsAll operations were successful. The operative time ranged from 65-213 min (mean 129 min) and the blood loss ranged from 50-350 ml with an average of 148 ml. One hundred and twenty-four patients (90.5%) were discharged from hospital without complications within 7 d after operation. Postoperative bile leakage occurred in 13 patients (9.5%) consisted of 10 early stage cases (18.5%, 10/54) and 3 later stage cases (3.6%, 3/83), which were discharged with improvement by conservative treatment within 3 weeks after operation. Totally 113 patients (82.5%) were followed up for 2-54 months with a median time of 14 months, no residual or retained stone and biliary duct stricture occurred. ConclusionOnly with the strict indication and proficient surgical technology, primary suture after common bile duct exploration is a safe and effective way to choledocholithiasis.
ObjectiveTo explore the related risk factors of polypoid lesions of gallbladder (PLG) in civil aviation flight cadets and the health management measures for the risk factors. MethodsRetrospective analysis of the 2022 flight annual medical students, according to the B ultrasound examination results have PLG, divided into PLG group (n=128) and non-PLG group (n=150), collect the basic data of the students, and establish a multivariate logistic regression equation model to analyze the related risk factors of gallbladder polypoid lesions. ResultsThe results of univariate analysis showed that there was no significant difference between groups with hypertension, hyperlipidemia and hyperglycemia (P>0.05), but with age and body mass index, high total bilirubin in serum and hyperuricemia, regular schedule and diet, and sufficient exercise (P<0.05). The results of multivariate logistic regression equation model analysis showed that age, high serum total bilirubin, hyperuricemia, irregular sleep and rest, irregular diet and lack of exercise were independent risk factors for PLG. ConclusionsAge, high serum total bilirubin, hyperuricemia, irregular work and rest, irregular diet and lack of exercise are the main reasons for PLG in civil aviation flight cadets. Intervention and prevention of risk factors can effectively ensure their health and flight safety.
ObjectiveTo evaluate the safety and feasibility of laparoscopic hepatectomy. Methods A total of 25 patients with hepatocellular carcinoma or liver hemangioma received laparoscopic hepatectomy, and perioperative results were analyzed. ResultsOnly one patient was converted to open hepatectomy because of massive hemorrhage. Blood loss of all patients during operation ranged from 100-1 200 ml with an average of 400 ml. The total blood volume of transfusion was 200-1 000 ml (mean 400 ml) in 14 patients. The operative time was 0.8-4.0 h (mean 2.3 h). All patients had no complications such as bile leakage and infection, and discharged from hospital in 5-10 d (mean 8 d) after operation. ConclusionLaparoscopic hepatectomy is safe and feasible to some liver diseases, but should be used with caution for the patients with tumor diameter over 9 cm and hepatic large vessels invaded by cancer.
