[The characteristics and citation analysis of the publications in National Medical Journal of China during 2016].
Objective: To analyze the characteristics and citations of articles in National Medical Journal of China (NMJC) during 2016, and to discuss the academic level and quality of the journal. Methods: All the literature published in NMJC during 2016 were retrieved through the Chinese Medical Citation index, and the citation frequency data in China's core journals of science and technology from January 2017 to December 2018 was obtained through Institute of Scientific and Technical Information of China. The citation status of articles published in NMJC was statistically analyzed by the method of literature metrology. ⋯ From 2017 to 2018, papers published in NMJC were cited 2 077 times by a total of 490 journals. Conclusions: The guidelines published in NMJC is highly cited. The editorial department should adjust the column setting timely, strengthen the planning of key topic selection and the solicitation and publicity of excellent papers, and further improve the influence of the magazine.

[The value of conventional magnetic resonance imaging based radiomic model in predicting the texture of pituitary macroadenoma].
Objective: To investigate the value of conventional magnetic resonance imaging (MRI) based radiomic model in predicting the texture of pituitary macroadenoma. Methods: The complete data of 101 patients with pituitary macroadenoma confirmed by surgery and pathology in Yijishan Hospital of Wannan Medical College from December 2014 to December 2019 were retrospectively analyzed. According to the texture of the intraoperative pituitary tumor, patients were divided into soft group (n=58) and hard group (n=43). ⋯ Results: The AUC (Area Under the ROC Curve) (95%CI) values of T1WI, T2WI, enhanced T1WI, and the combined sequence model to predict the texture of pituitary macroadenomas in the training and validation groups were 0.91 (0.84-0.98) and 0.90 (0.78-1.00), 0.86 (0.78-0.95) and 0.83 (0.64-1.00), 0.90 (0.83-0.97) and 0.89 (0.77-1.00),0.92 (0.85-0.98) and 0.91 (0.79-1.00), respectively. DCA demonstrated that T(1)WI, T(2)WI, enhanced T(1)WI, and combined sequence model all had good net benefits in clinical practice. Conclusions: T(1)WI, T(2)WI, enhanced T(1)WI, and combined sequence model of conventional MRI all had high efficacy in predicting the texture of pituitary macroadenoma, which provided a new quantitative method for predicting the texture of pituitary macroadenoma.

[Effect of posterior lumbar fusion on the degeneration of adjacent segments using cortical bone trajectory screw fixation].
Objective: To compare the degenerative changes of adjacent segments after posterior lumbar fusion surgery using cortical bone trajectory (CBT) screws and pedicle screws (PS) in lumbar spinal degenerative disease. Methods: According to certain inclusion and exclusion criteria, prospective non-randomized study on cases of the single-segment lumbar spinal fusion surgery using cortical bone trajectory screws fixation and pedicle screws fixation in Beijing Chao-Yang Hospital from January 2015 to February 2016 was performed. The intervertebral space height (ISH), foramen height (FH), foramen width (FW), cephalad adjacent segment (CAS) and intervertebral disc degeneration grades at MRI scans were measured before surgery and during follow-up. ⋯ During follow-up, 4 cases (12.1%) of R-ASD and no S-ASD were found in the CBT group, while 12 cases (33.3%) of R-ASD appeared in the PS group, which was significantly higher than that in the CBT group (χ(2)=4.35, P=0.04). According to MRI, the adjacent discs of PS group had significantly more severe degeneration at the last follow-up than the CBT group (Z=-2.14, P=0.03). Conclusions: Compared with the PS fixation fusion, the CBT screw fixation can effectively reduce the occurrence of adjacent segment degeneration.

[Stress, anxiety, depression and insomnia in adults outside Hubei province during the COVID-19 pandemic].
Objective: To investigate the severity of stress, anxiety, depression and insomnia during the novel coronavirus disease (COVID-19) pandemic in adults outside Hubei Province, China. Methods: An online survey of psychological and sleep by using Questionnaire Star program from 5th to 19th February 2020 was conducted. The Impact of Event Scale-Revised was used to assess COVID-19 outbreak-related stress symptoms. ⋯ Conclusion: The COVID-19 outbreak resulted in related stress response and widespread increase in anxiety, depression, and insomnia outside Hubei Province, China in the general population. The aggravation of anxiety, depression and insomnia is associated with stress levels. Our data demonstrate that the widespread psychological and insomnia problems in the general population need to be addressed at the early phase of the pandemic.

[Acute kidney injury diagnosed by elevated serum creatinine increases mortality in ICU patients following non-cardiac surgery].
Objective: To analyze whether acute kidney injury (AKI) patients diagnosed by elevated serum creatinine had a higher risk of in-hospital mortality following non-cardiac surgery compared with those diagnosed by oliguria alone according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Methods: This was a secondary analysis of a previous retrospective cohort study. A total of 729 consecutive adult patients with high risk of AKI admitted to the intensive care unit (ICU) of Peking University First Hospital after non-cardiac surgery were enrolled in the previous study from July 2017 to June 2018. ⋯ Multivariate logistic regression analysis revealed that AKI-Scr (OR=20.286, 95%CI: 2.544-161.797, P=0.004) and preoperative hypoproteinemia (OR=4.897, 95%CI: 1.240-19.329, P=0.023) were independent risk factors for in-hospital mortality in postoperative AKI patients. Conclusions: AKI patients diagnosed by increased serum creatinine had a higher risk of in-hospital mortality following non-cardiac surgery, accompanied by several worsen short-term outcomes and higher total medical costs, compared with those diagnosed by oliguria alone according to the KDIGO criteria. More attention should be paid to AKI patients diagnosed by elevated serum creatinine, to improve the prognosis.
