目的 探討胰性腦病的可能的發病機制、發病情況及防治措施.方法 計算機檢索中文科技期刊全文數據庫(1989～2004),收集有關胰性腦病的臨床研究,并進行統計分析.結果 共納入43篇文獻,435例患者.胰性腦病在重癥急性胰腺炎中的發病率遠高于輕癥急性胰腺炎;發病年齡趨向中、老年;病死率為43.67%;病因仍以膽系疾病為主;伴發低氧的幾率不高于未并發胰性腦病患者.結論 胰性腦病的發生可能是多因素共同作用的結果,仍需進一步探討其發病機制.血清髓鞘堿性蛋白有望成為有價值的診斷指標.防治以治療原發病急性胰腺炎為主,重在預防.胰酶抑制劑和早期營養支持有一定預防作用.
Objective To evaluate the effects of mass immunization campaign on the epidemiological characteristics of measles. Methods Comparison was made between the incidences of measles before and after the mass immunization campaign in 2007 in Shunqing prefecture of Nanchong city. Results The total number of the reported measles cases reached 460 during 2004 to 2007 in Shunqing prefecture of Nanchong city, and the respective annual rates of incidence were 4.04, 23.53, 11.84, and 33.57, respectively per 100 000 heads. Cases reported from April to July accounted to 73.91% of the total (340/460). Children under 15 were reported to have the highest incidence rate and accounted to 83.70% of the total (385/460), of which incidences of children under 1 accounted to 0%, 10.81%, 13.51% and 25.82%, respectively. Only 20.00% of the subjects (92/460) in this study had a definite history of measles vaccination. After the mass immunization campaign in September, 2007, only 10 cases were reported in 2008 and the incidence rate was 1.58 per 100 000 heads, a 95.29% decrease in incidence rate in comparison with that of the last year. Conclusion The mass immunization campaign has achieved substantial results.
ObjectiveTo summarize the research progress of relationship between distal landing zone geometric and outcomes of endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm. MethodsThe domestic and foreign literature on the accumulation of the impact of proximal and distal landing zone geometric morphology on clinical outcomes, the evaluation methods for related complications of proximal and distal landing zones, preventive measures for adverse outcomes related to the geometric morphology of the distal landing zone, and the pathophysiological mechanisms of complications related to the distal landing zone were retrieved to make an review. ResultsThe irregular geometric morphology of the proximal landing zone was closely associated with adverse events following EVAR. The morphology of the distal landing zone was actually more complex than that of the proximal zone, and the measurement methods for its parameters were also more complicated. Common methods used in the literature for studying landing zones included the centerline distance method, the minimum distance method, and the landing area method. Primary preventive measures for adverse outcomes related to the geometry of the distal landing zone included increasing radial support force and contact area, using endostaples, and extending the landing zone. In addition to anatomical factors, the distal landing zone was also influenced by various pathophysiological factors. ConclusionsThe morphology and related pathological changes of the distal landing zone significantly impact the clinical outcomes following EVAR for abdominal aortic aneurysm. However, current research on the distal landing zone is limited. Future studies should focus on developing new technologies and methods to improve the evaluation and management of the distal landing zone, thereby reducing the complications after EVAR, enhancing the success rate of the surgery, and improving patient survival quality.
Objective To systematically review the psychological resilience intervention in China, so as to evaluate its effectiveness. Methods Studies published as of October 2012 were searched in CBM, VIP, CNKI and WanFang Data. The randomized controlled trials (RCTs) and controlled before-and-after trials (CBAs) about psychological resilience intervention were included. Two reviewers independently performed screening, quality assessment and data extraction, and then reached a consensus after cross-check and discussion. Qualitative synthesis was adopted instead of meta-analysis for the existed significant deviations in outcomes of included studies. Results A total of 8 studies including 3 RCTs and 5 CBAs were included for the analysis. All the studies referred to the objects of students, including 6 for college students, 1 for secondary school students and 1 for left behind students in rural junior school. All 8 studies evaluated the effectiveness of group psychological guidance, 1 of which also compared the outcomes of psychological lectures. All the included trials suggested that group psychological guidance and psychological lectures might significantly improve the psychological resilience of subjects. Conclusion Current studies on psychological resilience intervention are limited, the measure has been taken seems relatively single, which mainly focuses on students and lacks of high-quality research design. It suggests take more diverse psychological resilience interventions for different population, and evaluate both short-term and long-term effectiveness by performing large sample, strictly designed and high-quality trials.
Wuhan Leishenshan Hospital was built within 12 days during the key period of fighting against coronavirus disease 2019 (COVID-19) in Wuhan. It was a field infectious disease hospital with 1500 beds. Due to the emergency of the epidemic situation, the operation mode of “parallel of construction, acceptance, training and treatment” was employed. During the peak period, nearly 3000 medical workers and 13000 builders worked on the same site. In 67 days, 2 011 patients with COVID-19 were treated. Through the bundle infection prevention and control (IPC) measures, Wuhan Leishenshan Hospital achieved zero infection, zero accident, and low level pollution of SARS-CoV-2 (0.3%) by environment monitoring. The bundle IPC measures of Leishenshan Hospital not only provided prevention and control experience for other field infectious disease hospitals at domestic and abroad during the period of COVID-19, but also put forward ideas and work flow for other medical institutions to deal with emerging infectious diseases.
