  • Analysis of the status of evidence for disease burden research

    ObjectivesTo conduct a bibliometric analysis to research the status of disease burden domestically and overseas so as to understand the status of diseases burden, and to provide scientific and reasonable reference for health disease prevention, control strategies formulation and future research.MethodsPubMed, Web of Science, EMbase, The Cochrane Library, WanFang Data, CBM and CNKI databases were electronically searched to collect literature on disease burden from inception to October, 2018. Two reviewers independently screened literature and extracted data. EndNote X7 software was used for literature management, Excel 2016 software and VOS viewer software were also used to analyze data. Literature was classified by the aspects of literature publication characteristics, diseases, background areas, influencing factors, evaluation indicators and poverty caused by illness.ResultsA total of 325 studies were included in the bibliometric analysis. 41 articles (12.6%) were published in journals indexed by SCIE; original research evidence accounted for 97.0% (315 articles); 272 articles were from China (83.7%). The main diseases involved were malignant tumors (58 articles, 17.8%), diabetes (29 articles, 8.9%) and hypertension (24 articles, 7.4%). Factors affecting the disease burden primarily included hospitalization days (9 articles, 2.8%), complications (5 articles, 1.5%), delays in treatment (5 articles, 1.5%), and economic income (4 articles, 1.2%). Sixity-one articles (18.8%) reported poverty due to illness, and related diseases were chronic obstructive pulmonary disease (12 articles, 3.7%), hypertension (10 articles, 3.1%), diabetes (10 articles, 3.1%), malignant tumors (9 articles, 2.8%) and hepatitis B (6 articles, 1.8%).ConclusionsAt present, the disease burden research are focusing more on the burden of chronic non-communicable diseases such as malignant tumors, hypertension, diabetes, cardiovascular and cerebrovascular diseases in developing countries and regions. Medical costs vary from different diseases and treatment, different demographic characteristics of patients, and the coverage medical security of different population are the primary reasons for the " expensive in medical treatment” of current residents and the heavy burden of disease. DALY and total direct medical expenses are the main evaluation indexes of epidemiological burden and economic burden of disease, respectively. Future researches should focus on strengthening the scientific nature of study design to improve the quality of research, as well as paying more attention to diseases and aspects that are rarely involved, such as major diseases caused by poverty due to illness, comprehensive analysis of multiple diseases and aspects of health investment measurement, and comprehensively use the evaluation indicators of disease burden to strengthen the research on the comparability index of disease economic burden.

  • Antibody microarray analysis of the tissue apoptosis factors in patients with hepatic alveolar echinococcosis

    Objective To detect and analize the expressions and it’s clinical significance of apoptosis factors in hepatic alveolar echinococcosis tissues by using antibody chip technology. Methods The liver tissue specimens (including the edge of lesions and normal liver tissues) of surgical resection of 6 patients with hepatic alveolar echinococcosis in Affiliated Hospital of Qinghai University were collected. The tissue protein was extracted and the level of apoptosis was detected by antibody chip technology. The data were analyzed by AAH-APO-G1 software. Results The expression levels of 5 kinds of apoptosis factors (Bad, Fas, IGFBP-3, P21 and XIAP) in the liver tissues of the marginal zone of hepatic alveolar echinococcosis were compared with that of the normal liver tissues, and the difference was statistically significant (P<0.05). The expression levels of Bad, Fas, IGFBP-3 and P21 were up-regulated, and the expression level of XIAP was down regulated. Conclusions Apoptosis-related factors play a role in the progression of the hepatic alveolar echinococcosis, there may be contact with the immune escape mechanisms, while promote apoptosis factor and inhibitory apoptosis factor that may exist the function imbalance, so more in-depth exploration the mechanism of apoptosis factors on hepatic alveolar echinococcosis in diagnosis and treatment have important significance.

  • Literature review of the diagnosis and treatment of bone hydatid disease in China from 1975 to 2015

    Objective To analyze the clinical manifestations, diagnosis, treatment and prognosis of bone hydatid disease in China by literature review. Methods We searched the databases of China National Knowledge Infrastructure and Wanfang for case reports of bone hydatid disease published from 2000 to 2015 in China. Data were extracted by using a standardized form and a retrospective clinical analysis was performed. Results A total of 21 relevant literatures published from 2000 to 2015 were included, including 87 cases of bone hydatid disease treated from 1975 to 2015. The regional distribution of bone hydatid disease was mainly concentrated in the animal husbandry areas in China. In terms of diagnosis basis, imaging examination was mentioned in 54 cases (62.1%), laboratory examination was mentioned in 32 cases (36.8%), and pathologic examination was mentioned in 8 cases (9.2%), etc. Surgical treatment was the main treatment, and some treatments were combined with chemotherapy. The outcomes of bone hydatid disease were relatively poor. In the 44 cases whose outcomes were reported, 26 cases (59.1%) had recurrence, 18 cases were cured (40.9%), 10 cases (22.7%) underwent re-operation, and 2 cases (4.5%) died. Conclusions Bone hydatid disease is rare. Surgical treatment is still the main method for treating bone hydatid disease. The rate of recurrence of bone hydatidosis is relatively high, so it is very important to explore new methods for diagnosis and treatment of bone hydatid disease.

  • Generation and reporting of evidence mapping

    Evidence mapping is a new type of comprehensive evidence research method that systematically collects, evaluates, and synthesizes existing evidence to clarify research status and gaps, thereby promoting scientific research and decision-making. After nearly 20 years of development, the methodology of evidence mapping has been continuously improved, and has gained wide attention and recognition from the international community. China has paid much attention to evidence mapping at an early stage, but there are relatively few theoretical and practical researches, and the concept definition is inconsistent. This paper introduces the methodology of evidence mapping production and reporting for researchers to use for reference, with a view to further promoting the research and development of evidence mapping in China.

  • The impact of school breakfast programs on children's nutrition and health: a systematic review

    ObjectiveTo systematically review the impact of school breakfast on children's nutrition and health. MethodsThe PubMed, Web of Science, The Cochrane Library, EMbase, CNKI, CBM, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on the impact of school breakfast on children's nutrition and health from inception to June 2022. 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 RevMan 5.4 software. ResultsA total of 8 RCT, involving 8 208 children were included. The results of meta-analysis showed that compared with non-school breakfast, the school breakfast could significantly improve the rate of school attendance (RR=1.38, 95%CI 1.26 to 1.51, P<0.000 1). However, there was no statistically significant difference in height, weight, weight-for-age, height for age, energy, protein, iron, or incidence of nutritional disease between the groups. ConclusionThe current evidence suggests that school breakfast has no impact on children's nutrition and health. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
