Objective Sleep is an important physiological process for maintaining normal cognitive functions,but with the accelerated pace and increased work pressure in modern society,sleep deprivation has become a common phenomenon.It has been shown that sleep deprivation interferes with higher cognitive functions such as working memory,but the specific mechanism of its effect is still not completely clear.The present study aimed to systematically investigate the effects of 36 hours of sleep deprivation on the stages of the working memory processing chain and its neural mechanisms through behavioral and event-related potential(ERP)techniques.Methods Using a randomized controlled experimental design,48 healthy adult subjects were recruited and randomly assigned to sleep deprivation and control groups.All subjects completed a 2-back phonological working memory task,and behavioral data(response time and correctness)and ERP data(P2,N2,and P3 component wave amplitudes)were collected at 0 and 36 hours,respectively.The effects of sleep deprivation on working memory behavioral performance and neurophysiological indices were assessed by ANOVA.Results Behavioral results showed that the sleep deprivation group had a significantly longer response time after 36 hours,but no significant decrease in correctness,indicating a decrease in response efficiency but stable accuracy.ERP results showed that P2 amplitude did not change significantly before and after sleep deprivation,indicating that the early perception and categorization stages were limitedly affected by sleep deprivation;whereas,N2 and P3 amplitudes decreased significantly after sleep deprivation,reflecting that later cognitive processing such as conflict monitoring and resource allocation and other late cognitive processing were significantly disturbed.Conclusion Through ERP technology,this study uncovers the phased impact of 36-hour sleep deprivation on the working memory processing chain.The study found that early perceptual and categorization stages may be less susceptible to the effects of sleep deprivation,likely due to their relatively automatic processing and lower demand for cognitive resources.In contrast,during later stages of cognitive processing,particularly in higher-order functions such as conflict monitoring and resource allocation,sleep deprivation significantly impaired task performance efficiency by disrupting prefrontal cortex function.This finding deepens the understanding of the mechanisms underlying the effects of sleep deprivation and provides a scientific basis for cognitive intervention and management strategies in high-stress occupational groups.Future studies can further explore the long-term effects of sleep deprivation and its neural mechanisms by combining multimodal techniques.

OBJECTIVE To provide a detailed report and interpretation of the method and results for determining the weights of the technical indicators from the “multi-dimensional and multi-criteria comprehensive evaluation index system （first edition）” stated in Guideline for Multi-dimensional and Multi-criteria Comprehensive Evaluation of Chinese Patent Medicine. METHODS Normalization calculations were performed on the comprehensive weight values calculated by the analytic hierarchy process and expert weighting method to obtain the objective weights of the indicators. RESULTS The weight results of the six primary dimensions in the current comprehensive evaluation indicator system of Chinese patent medicine showed effectiveness dimension＞ safety dimension＞standard dimension＞application dimension＞scientific dimension＞economic dimension， with weight values of 0.281 0， 0.268 5， 0.195 8， 0.107 3， 0.096 1 and 0.051 3 respectively， consistent with the results of most researches currently. CONCLUSIONS The process of weight determination in this indicator system is scientifically reasonable， with clear methods and clear interpretations， and is worthy of further optimization and widespread application.

In developing rapid and living guidelines of traditional Chinese medicine （TCM） in response to public health emergencies， it is important that evidence continue to be reviewed， and clinical questions and recommendations updated if necessary， due to the rapid changes in disease progression and the continuous generation of relevant research evidence. This paper proposed that the updating scope in dynamic mode should first be identified； then evidence monitoring should be carried out in four aspects， including clinical research， related guidelines or laws and regulations， disease progression， as well as clinical use of recommendations and clinical needs； finally， based on the results of the evidence monitoring， different options should be made， including revising the clinical questions， updating the evidence and recommendations， and withdrawing the guideline.

Objective:To evaluate the safety and efficacy of tumor-treating fields (TTFields) and chemoradiation in patients with high-grade glioblastoma.Methods:Clinical data of 38 patients admitted to the Jiangsu Cancer Hospital from September 2021 to May 2023 who were diagnosed with high-grade glioblastoma (36 cases of World Health Organization grade Ⅳ and 2 cases of grade Ⅲ) were retrospectively analyzed. All patients received TTFields combined with concurrent chemoradiation after surgery. Response assessment in neuro-oncology (RANO) criteria was used to evaluate the glioma responses as tumor remission, stable or progression. Common terminology criteria for adverse events v5.0 and TTFields related skin adverse reaction (dAE) criteria were used to evaluate the adverse events. Treatment compliance was assessed by data on the NovoTTF-200A therapeutic device, calculated as a percentage of daily TTFields usage time. Survival analysis was estimated by the Kaplan-Meier method and compared by the log-rank test.Results:The median duration of treatment with TTFields in 38 patients was 20 h (rang: 2.4-22.6 h), and the median treatment compliance was 83% (range: 10%-94%). After 42 days of TTFields combined with concurrent chemoradiation, 12 patients who underwent complete tumor resection were assessed as stable according to RANO criteria. Among the 26 patients who underwent partial tumor resection, 23 (88%) were evaluated as disease remission according to RANO criteria. The 7-, 10-, 13-month progression-free survival rate was 81.0%、64.0%、49.5%, repectively. The common adverse events included grade 1 (45%) and grade 2 (8%) dAE, without grade 3-4 dAE. Typical presentations included contact dermatitis, blisters, lesions or ulcers, and abscesses. The median follow-up time was 10.0 months (range: 1.6-21.3 months). At follow-up as of July 2023, 26 of the 38 patients were stable and 12 had disease progression (8 died).Conclusion:The preliminary results show that TTFields combined with chemoradiation is effective, safe and reliable treatment for high-grade glioblastoma.

Objective To evaluate the risk of bias and reporting quality in randomized controlled trials(RCTs)of the Chinese medicine injection for acute cerebral infarction in the last five years.Methods RCTs literature on Chinese medicine injection in the treatment of acute cerebral infarction was systematically searched in CNKI,Wanfang Data,VIP,China Biology Medicine Database(CBM),PubMed,Embase and Cochrane Library from April 20,2018 to April 20,2023.The risk of bias and reporting quality of included RCTs were evaluated using the Cochrane Risk of Bias Tool(ROB 1.0)and CONSORT-CHM Formulas 2017,respectively.Results A total of 4 301 articles were retrieved,and 408 RCTs were included according to inclusion and exclusion criteria.The ROB evaluation results showed that the the majority of studies were rated as having an unclear risk of bias due to the lack of reporting on allocation concealment,blind method,trial registration information,and funding sources.The evaluation results of CONSORT-CHM Formulas 2017 showed that the number of reported papers of 17 items was greater than or equal to 50%,and the number of reported papers of 25 items was less than 10%,and most of the RCTs did not show the characteristics of TCM syndrome differentiation and treatment.Conclusion The quality of Chinese medicine injection in the treatment of acute cerebral infarction RCTs is generally low.It is recommended that researchers refer to the methodology design of RCTs and international reporting standards,improve the trial design,standardize the trial report,and highlight the characteristics of TCM syndrome differentiation and treatment.

WHO Guideline on Country Pharmaceutical Pricing Policies,published in 2020,outlines 10 commonly used pricing methods internationally.However,due to the unique composition of costs for traditional Chinese medicine(TCM),directly applying pricing methods designed for chemical and biological drugs may lead to discrepancies.Currently,in China,drug pricing primarily in-volves internal reference pricing,tender negotiation pricing,promoting the use of quality-assured generic and biosimilar drugs,and centralized procurement.It systematically analyzes various pricing methods and identifies their applicability and underlying reasons concerning the pricing of TCMwithin the medical insurance system.The method of value-based pricing and increasing price transparency has advantages for the pricing regulation of traditional Chinese medicine under medical insurance.

Objective:To explore the medication law and core Traditional Chinese Medicine (TCM) compounds in the treatment of blood stasis vascular dementia (VD) based on data mining.Methods:The literature about TCM treatment for blood stasis VD was retrieved from the databases of CNKI, Wanfang, VIP, and CBM from January 2000 to November 2021. Microsoft Office Excel 2019, SPSS Modeler 18.0, SPSS Statistics 25.0, R X64 4.1.2, and Origin 2021 were used to perform medication frequency analysis, frequency analysis of four properties and five tastes of TCM, association rules, clustering analysis, factor analysis and data visualization.Results:A total of 196 articles were included, with 196 TCM prescriptions, involving 200 kinds of Chinese materia medica. High-frequency drugs were for Acori Tatarinowii Rhizoma, Chuanxiong Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Polygalae Radix, Carthami Flos. The medicinal properties were mainly warm, mild and cold, the tastes were mainly sweet, bitter and pungent, and the meridians were mainly liver meridian, spleen meridian and heart meridian. A total of 19 association rules were obtained from the analysis of association rules for 2 kinds of Chinese materia medica, and the rules of the representative were Acori Tatarinowii Rhizoma- Polygalae Radix, Chuanxiong Rhizoma- Carthami Flos, Acori Tatarinowii Rhizoma- Curcumae Radix. A total of 4 categories were extracted through clustering analysis. Factor analysis extracted a total of 8 common factors. Conclusion:The core pathogenesis of blood stasis VD is blood stasis blocking brain collaterals, and there were also pathological factors such as qi deficiency, yin deficiency, phlegm turbidity and so on. The basic treatment is promoting blood circulation and removing stasis, and different methods of promoting blood circulation and drugs are selected. The methods of strengthening spleen and reducing phlegm, nourishing yin and blood, inducing resuscitation, tonifying the kidney and spleen, regulating qi, promoting collaterals and so on can also be used based on syndromes and symptoms of the patients.

Objective: To compare the percutaneous transluminal septal myocardial ablation (PTSMA) and percutaneous transluminal septal tunnel myocardial ablation (PTSTMA) on cardiac function in experimental canines.
Methods: According to CAG determined coronary septal branches, a total of 25 hybrized canines were divided into 2 groups:PTSMA group, n=13 canines with the bigger septal branches and PTSTMA group, n=12 canines with the smaller or uneven septal branches. Alcohol ablation model was established. Electrocardiograph (ECG) at before and after the operation, biomarkers for myocardial injury, echocardiography and hemodynamic changes were recorded. The animals were scariifes at 1 week after operation, the pathological changes in ventricular septal were observed by HE and Masson staining.
Results: Myocardial infarction (MI) could be induced by either PTSMA or PTSTMA and the thickness of septal was decreased. LVEDd, LVEF and hemodynamic indexes were similar between 2 groups. The alcohol volume used in operation, EKG and echocardiography ifndings were similar between 2 groups, P>0.05. Pathological staining indicated that there was a well-demarcate between the ablation focal and normal myocardium, merging area had neutrophiles invasion, infarcted cells were partially having the ghost cell sample and they were gradually replaced by ifbrous tissue. There was nest-like necrosis in ablated lumen and the normal vessel wall disappeared. PTSMA group had vessel lumen conifguration in septal branch and the necrosis limited inside the lumen;while in PTSTMA group, the vessel wall of was discontinued and some necrosis materials move out to from lumen.
Conclusion: Both PTSMA and PTSTMA were effective for alcohol septal ablation in different coronary septal branches, the impacts on cardiac function and hemodynamic changes were similar in experimental canines.

Objective To investigate the characteristics of coronary vessel re-endothelialization after placement of drug-eluting stents (DES), and to provide clinical evidence for the double anti-platelet treatment. Methods Optical coherence tomography (OCT) was performed in 43 patients in 1 year after DES implantation. Characteristics of re-endothelialization and percentage of neointimal coverage of stent struts were evaluated by OCT. Results The rate of stent struts intimal coverage was 90.70%, and the remain was lack of endothelial coverage; The ratio of neointimal thickness (NIT) between 0-99, 100-199 and above 200 microns was 19.92%, 37.55% and 42.53%, respectively. The rate of neointimal coverage was higher and the degree of neointimal hy-perplasia was more extensive in patients with DM and in patients with ACS than those of patients without DM and of patients with stable angina pectoris. Conclusion One year after stent placement, most of the stent struts were covered with neointima and few struts obtained poor coverage of endothelial. DM and ACS may be impact factors for the progress of re-endothelialization after DES placement.
