For better adaptation to clinical work and scientific research as well as self-development,medical postgraduates are required to improve their reading ability to harvest information from medical English articles.Constructing formal schema based on linguistic schema and enriching content schema can significantly enhance medical English reading ability,according to schema theory and education practice.Therefore,the learning mode was explored based on schema theory and this theory was applied in practice to elevate reading ability by means of reading report.

The present study is aimed to investigate the early clinical effects of nano-hydroxyapatite/polyamide 66 intervertebral fusion cage (n-HA/PA66 cage) for the treatment of lumbar degenerative diseases. We selected 27 patients with lumbar degenerative diseases who were managed by posterior decompression or reset operation combined with n-HA/PA66 cage intervertebral fusion and internal fixation from August 2010 to January 2012. The oswestry disability index (ODI), low back and leg pain visual analogue score (VAS), and intervertebral height (IH) were evaluated at preoperation, 1 week postoperation and the last follow-up period, respectively. Intervertebral bony fusion was evaluated at the last follow-up time. The patients were followed up for 12-24 months (averaged 19 months). The ODI, VAS and IH were significantly improved at 1 week postoperation and the last follow-up time compared with those at preoperative period (P < 0.05). But there was no significant difference between 1 week postoperative and the last follow-up time (P < 0.05). Brantigan's standard was used to evaluate fusion at the last follow-up time. There were 19 patients with grade 5 fusion, 8 with grade 4 fusion, with a fusion rate of 100%, and none with grade 1-3 fusions. There was no cage translocation and internal fixation breakage. These results suggested that n-HA/PA66 cage was an ideal biological material in the posterior lumbar interbody fusion and internal fixation operation for treatment of lumbar degenerative diseases. It can effectively maintain the intervertebral height and keep a high rate of bony fusion. The early clinical effect has been satisfactory.

Objective:To develop an expert consensus on safety management of inpatients with Alzheimer's disease (AD) (referred to as the " Consensus") and standardize safety management strategies for AD inpatients. Methods:The evidence on safety management of AD inpatients was searched, evaluated, and summarized, with a search period from database establishment to July 31, 2023. This study conducted methodological quality evaluation and evidence extraction on the included article to form a consensus draft. A total of 24 experts from 15 hospitals across the country were selected for two rounds of Delphi expert consultation to analyze, revise, and improve their opinions, forming the final draft of the Consensus. Results:The positive coefficients for both rounds of expert consultation were 100.00% (24/24). In the second round of consultation, the expert judgment basis coefficient was 0.925, familiarity level was 0.846, authority coefficient was 0.886, Kendall harmony coefficient was 0.044 ( P<0.01). The Consensus elaborated on five common safety problems (loss, falling, aspiration/choking, self-injury/other injury, and medication errors in AD inpatients) from three aspects (assessment, identification of risk factors, and nursing strategies) . Conclusions:The Consensus is scientific and practical to a certain extent, providing guidance and reference for the safety management practice of AD inpatients.

Objective To investigate the application value of point-of-care lung ultrasound(POC-LUS)scoring in selecting respiratory support treatment modalities for neonatal infectious pneu-monia(NIP).Methods A total of 89 NIP patients were selected as the study subjects and divided into control group(no assisted ventilation)with 46 cases,noninvasive group(noninvasive assisted ventilation)with 28 cases,and invasive group(invasive mechanical ventilation)with 15 cases based on the degree of dyspnea and blood gas analysis results.The POC-LUS scores of the three groups were compared,and the correlations of POC-LUS scores with arterial oxygen partial pressure[pa(O2)]and arterial carbon dioxide partial pressure[pa(CO2)]were analyzed.Receiver operating characteristic(ROC)curves were plotted to assess the predictive efficacy of POC-LUS scores for the need for nonin-vasive assisted ventilation or invasive mechanical ventilation in NIP patients.Results The POC-LUS scores of the noninvasive group and the invasive group were(31.7±7.3)and(42.1±8.0),respec-tively,which were higher than(21.5±7.3)of the control group.Additionally,the score of the inva-sive group was higher than that of the noninvasive group(P＜0.05).Correlation analysis revealed a significant negative correlation between POC-LUS scores and pa(O2)(r=-0.802,P＜0.05),and a significant positive correlation with pa(CO2)(r=0.807,P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of POC-LUS scores for predicting the need for noninvasive assisted ventilation and invasive mechanical ventilation were 0.918(95％CI,0.862 to 0.973)and 0.938(95％CI,0.889 to 0.987),respectively.The sensitivity was 0.767 and 0.933,and the specificity was 0.935 and 0.824,with optimal cutoff values of 29.5 and 31.5,respectively.Conclusion POC-LUS scoring can quantitatively assess the severity of lung lesions in NIP patients and serves as a guiding tool for clinicians in selecting assisted ventilation treatment modalities.
