Interpretation of Consolidated Health Economic Evaluation Reporting Standards 2022 / 中华流行病学杂志

The number of studies related to health economics evaluation is increasing. Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022) contains 28 items. Based on CHEERS 2013, CHEERS 2022 adds a health economic analysis plan, model sharing, and community, patient, public, and other relevant stakeholders' participation in the statement, taking into account the future development direction of health economics evaluation. It provides a useful review tool for peer reviewers, editors, and readers and supports health technology assessment agencies in establishing standard reporting standards for health economics evaluations. In this study, we briefly introduced and interpreted the CHEERS 2022 statement and analyzed an example of health economics evaluation in infectious disease epidemiology to provide a reference for researchers to report studies regarding health economics evaluation standardly.

The Relationship between nm23 and p16 Gene Synergy Expression and Gastric Cancer Biological Characteristic and Prognosis / 中国肿瘤生物治疗杂志

Objective: To examine and analyze the nm23, p16 gene expression in gastric cancer tissure,and follow up patients 5 years to discuss the relationship between nm23 and p16 gene synergy expression and gastric cancer biological characteristic and prognosis.Methods: nm23 and p16 protein in gastric cancer tissue and control were detected by immunohistochemistry,and the patients had been followed up for 5 years. Results: In 84 samples of gastric cancer, nm23 positive rate was 46.43%, p16 was 44.05%, the positive rate of gastric cancer tissue and metastasitic lymph node was lower than that of normal control, normal tissue near cancer or benign polyp,and these two genes were related to the depth of tumor invasion and clinical stage.The mortality and recurrence-metastasis rate was higher in these low expression group, and had a shorter median survive period. Conclusion: Abnormal expression of nm23 and p16 gene plays a important role in gastric cancer recurrence and devolepment and may be one of markers for evaluating tumor biological behavior and prognosis.
