OBJECTIVE To conduct a comprehensive clinical evaluation of four nucleoside （acid） analogues that have been approved and marketed in China， such as entecavir， tenofovir disoproxil fumarate， tenofovir alafenamide fumarate， and tenofovir amibufenamide. METHODS According to the Guideline for the Administration of Clinical Comprehensive Evaluation of Drugs （2021 edition， trial implementation）， a comprehensive search was conducted across databases including CNKI， Wanfang Data， VIP， PubMed， the Cochrane Library， Embase， as well as relevant official websites. Drug package inserts， guidelines， consensus statements， and relevant literature for the four drugs were collected and subjected to a comprehensive evaluation across six dimensions： safety， efficacy， cost-effectiveness， innovativeness， suitability， and accessibility. RESULTS The scores for entecavir in terms of safety， efficacy， cost-effectiveness， innovativeness， suitability， and accessibility-along with its comprehensive score-were 13， 14， 13， 10， 18， and 6， totaling 74 points. For tenofovir disoproxil fumarate， the respective scores were 13， 17， 18， 8， 18， and 7， totaling 81 points. For tenofovir alafenamide fumarate， the scores were 14， 20， 12， 8， 18， and 5， totaling 77 points. Finally， for tenofovir amibufenamide， the scores were 10.5， 17， 10， 6， 15， and 4， totaling 62.5 points. CONCLUSIONS Tenofovir disoproxil fumarate， with the highest score， is recommended as the first-line option， suitable for adults， children， and pregnant women. However， caution is warranted for potential renal impairment. Tenofovir alafenamide fumarate is recommended as a second-line alternative， particularly for individuals at high risk for bone and renal damage. Entecavir has a score similar to tenofovir alafenamide fumarate but requires dosing on an empty stomach and dose adjustment based on renal function of patients. Tenofovir amibufenamide received the lowest score and is considered a weak recommendation. The clinical application of these nucleoside （acid） analogues should be individualized based on the patient’s age， physiological status， and risk factors.

ObjectiveThis study employed the scoping review method to systematically retrieve and analyze the basic information and clinical research evidence of expensive Chinese patent medicines （CPMs）， aiming to provide a basis for future related research and clinical applications. MethodsEight Chinese and English databases were systematically searched for the clinical research evidence on expensive CPMs. ResultsEleven expensive CPMs （Angong Niuhuang Wan， Jufang Zhibao Wan， Suhexiang Wan， Pien Tze Huang， Niuhuang Qingxin Wan， Qinggong Shoutao Wan， Compound Realgar Natural Indigo Tablets， Xihuang Wan， Dingkun Wan， Babao Wan， and Guilingji Capsules） were selected. A total of 365 related studies were included in this review， comprising 331 clinical studies （of which 291 were randomized controlled trials）， 30 systematic reviews and Meta-analyses， 3 expert consensus， and 1 rapid health technology assessment. Among the 11 CPMs， 2（Angong Niuhuang Wan and Jufang Zhibao Wan） had a daily price over 500 yuan. The famous and precious Chinese medicinal materials involved included Moschus （frequency of 7）， Bovisc Alculus （7）， and Borneol （5）. The dosage forms included pills， capsules， oral liquid， tablets， and lozenges. The diseases treated by these CPMs mainly included malignant tumors， cerebrovascular diseases， gynecological diseases， and hepatobiliary system diseases. The sample sizes of the clinical studies were mainly concentrated within the range of 51-100 cases， and the main control form was CPM + basic Western medicine treatment vs. basic Western medicine treatment. The 331 clinical studies reported a total of 44 adverse events occurred， of which 36 were determined to be adverse reactions. ConclusionThe scarcity of raw materials leads to the high prices of expensive CPMs. The difficulty of conducting clinical research and the critical and severe cases treated lead to a lack of clinical research evidence with large sample sizes. The uneven distribution of existing studies， incomplete information on medicine package， and non-standard clinical research designs remain to be addressed in the future.

The bidirectional closed-loop motor imagery brain-computer interface (MI-BCI) is an emerging method for active rehabilitation training of motor dysfunction, extensively tested in both laboratory and clinical settings. However, no standardized method for evaluating its rehabilitation efficacy has been established, and relevant literature remains limited. To facilitate the clinical translation of bidirectional closed-loop MI-BCI, this article first introduced its fundamental principles, reviewed the rehabilitation training cycle and methods for evaluating rehabilitation efficacy, and summarized approaches for evaluating system usability, user satisfaction and usage. Finally, the challenges associated with evaluating the rehabilitation efficacy of bidirectional closed-loop MI-BCI were discussed, aiming to promote its broader adoption and standardization in clinical practice.

Objective To investigate the feasibility of developing a grading diagnostic model for schistosomiasis-induced liver fibrosis based on B-mode ultrasonographic images and clinical laboratory indicators. Methods Ultrasound images and clinical laboratory testing data were captured from schistosomiasis patients admitted to the Second People’s Hospital of Duchang County, Jiangxi Province from 2018 to 2022. Patients with grade I schistosomiasis-induced liver fibrosis were enrolled in Group 1, and patients with grade II and III schistosomiasis-induced liver fibrosis were enrolled in Group 2. The machine learning binary classification tasks were created based on patients’radiomics and clinical laboratory data from 2018 to 2021 as the training set, and patients’radiomics and clinical laboratory data in 2022 as the validation set. The features of ultrasonographic images were labeled with the ITK-SNAP software, and the features of ultrasonographic images were extracted using the Python 3.7 package and PyRadiomics toolkit. The difference in the features of ultrasonographic images was compared between groups with t test or Mann-Whitney U test, and the key imaging features were selected with the least absolute shrinkage and selection operator (LASSO) regression algorithm. Four machine learning models were created using the Scikit-learn repository, including the support vector machine (SVM), random forest (RF), linear regression (LR) and extreme gradient boosting (XGBoost). The optimal machine learning model was screened with the receiver operating characteristic curve (ROC), and features with the greatest contributions to the differentiation features of ultrasound images in machine learning models with the SHapley Additive exPlanations (SHAP) method. Results The ultrasonographic imaging data and clinical laboratory testing data from 491 schistosomiasis patients from 2019 to 2022 were included in the study, and a total of 851 radiomics features and 54 clinical laboratory indicators were captured. Following statistical tests (t = −5.98 to 4.80, U = 6 550 to 20 994, all P values < 0.05) and screening of key features with LASSO regression, 44 features or indicators were included for the subsequent modeling. The areas under ROC curve (AUCs) were 0.763 and 0.611 for the training and validation sets of the SVM model based on clinical laboratory indicators, 0.951 and 0.892 for the training and validation sets of the SVM model based on radiomics, and 0.960 and 0.913 for the training and validation sets of the multimodal SVM model. The 10 greatest contributing features or indicators in machine learning models included 2 clinical laboratory indicators and 8 radiomics features. Conclusions The multimodal machine learning models created based on ultrasound-based radiomics and clinical laboratory indicators are feasible for intelligent identification of schistosomiasis-induced liver fibrosis, and are effective to improve the classification effect of one-class data models.

Objective:To investigate the status of nursing practice and organizational management for reperfusion therapy in ischemic stroke across medical institutions in Beijing.Methods:In June 2023, a survey was conducted among nursing managers from 62 medical institutions under the jurisdiction of the Beijing Stroke Treatment Quality Control and Improvement Center. The survey aimed to assess the current nursing practices and organizational management for reperfusion therapy in ischemic stroke.Results:Among the 62 medical institutions, 16.13% (10/62) had dedicated reperfusion therapy nurses for stroke, and 87.10% (54/62) had established specific nursing protocols and procedures for stroke reperfusion therapy within their departments. However, 27.42% (17/62) of these institutions based the development and updates of their protocols on experiential summaries rather than standardized guidelines. In terms of nursing practice, there was room for improvement in emergency identification and triage of suspected stroke patients, assistance with intravenous thrombolysis, patient condition monitoring, early rehabilitation, and related health education. Regarding nursing quality control, significant differences were observed between institutions that regularly conducted quality control of stroke reperfusion therapy nursing and those that organized regular training sessions for nurses in this area ( P<0.05) . Conclusions:While nursing practices and quality for stroke reperfusion therapy in Beijing are progressing, there are disparities in regional development. There is a high demand for specialized stroke nursing and targeted technical training.
