[Evaluation of methodological and reporting quality of domestic clinical guidelines for hyperuricemia].

This study aims to evaluate the methodological and reporting quality of diagnosis and treatment guidelines for hyperuricemia as well as the expert consensuses and promote the understanding and application of the diagnosis and treatment guidelines for hyperuricemia. With "hyperuricemia" "guidelines" "consensus" "recommendations" as the key words in titles, the authors searched for the published clinical guidelines on hyperuricemia in Chinese against CNKI, Wanfang, VIP, Medlive and the official website of the industry association. The retrieval time limit was until May 31, 2021. The appraisal of guidelines for research and evaluation Ⅱ(AGREEⅡ) and the reporting items for practice guidelines in health care(RIGHT) were employed to evaluate the methodological quality and reporting quality of 14 guidelines/consensuses included. The average scores of the guidelines/consensuses were 80.85%(48.61%-98.61%) for the domain of scope and purpose, 34.52%(0-69.44%) for the domain of stakeholder involvement, 35.53%(6.25%-92.19%) for the domain of rigor of development, 55.85%(23.61%-86.11%) for the domain of clarity of presentation, 26.19%(0-76.04%) for the domain of applicability, and 21.42%(0-50.00%) for the domain of editorial independence. Nine guidelines/consensuses were of medium overall quality with grade B recommendation, and five guidelines/consensuses were of poor quality with grade C recommendation. The RIGHT classified the fourteen guidelines/consensuses into one of high reporting quality, three of medium reporting quality, and ten of low reporting quality. The results of this study indicate that the standardization and rigor of the methodological quality and the reporting quality of the clinical guidelines/consensuses for hyperuricemia in China remain to be strengthened.

[Function of intersectin in endocytosis and exocytosis].

Intersectin is an evolutionarily conserved multifunctional adaptor protein with multifunctional domains. These domains interact with components of the endocytic and exocytic pathways, such as the clathrin mediating synaptic vesicle recycling, the protein related to endocytosis via caveolae, the with-no-lysine kinases related to the regulation of renal outer medullar potassium, and the Cdc42 mediating exocytic pathway. Recently, the understanding of intersectin function in the pathogenesis of endocrine tumor and many neurodegenerative diseases such as Down syndrome, Alzheimer disease has been deepened. This article reviewed the structure and roles in endocytosis/exocytosis and diseases of intersectin.

Clinical efficacy of recombinant human thrombopoietin combined with glucocorticoids in the treatment of immune thrombocytopenia.

OBJECTIVE: Herein, we aimed to determine the clinical efficacy of recombinant human thrombopoietin (rhTPO) combined with glucocorticoids for treating immune thrombocytopenia (ITP). METHODS: Clinical data of 87 patients with ITP admitted to our hospital were retrospectively analyzed, and patients were divided into two groups according to the treatment employed: 42 patients in the control group (CG) were prescribed glucocorticoids, and 45 patients in the study group (SG) received rhTPO combined with glucocorticoids. RESULTS: The total effective treatment rate in the SG (95.56%) was higher than that in the CG (76.19%) (P < 0.05). The SG achieved a platelet (PLT) count > 50 × 109/L faster and required fewer PLT transfusions than the CG (P < 0.05). At 1, 7, and 14 days after treatment, the PLT count increased in both groups and was higher in the SG than in the CG (P < 0.05). After treatment, CD3+, CD4+, and CD4+/CD8+ T cells increased, whereas CD8 + decreased in both groups, with the SG exhibiting a superior improvement to the CG (P < 0.05). Considering prothrombin time, activated partial thromboplastin time, and fibrinogen, differences between the two groups were not statistically significant, both before and after treatment (P > 0.05). CONCLUSION: rhTPO combined with glucocorticoids for treating ITP can effectively enhance the therapeutic effect, regulate the T lymphocyte subpopulation, rapidly increase the PLT level, and induce no significant effect on the coagulation function of patients, with good safety and high clinical promotion value.
