ObjectiveTo investigate the incidence rate of sarcopenia in patients with Wilson’s disease （WD）-related liver cirrhosis， as well as the risk factors for sarcopenia and their impact on clinical outcomes. MethodsA total of 140 patients with WD-related liver cirrhosis who were treated in The First Affiliated Hospital of Anhui University of Chinese Medicine from January 2019 to June 2020， and according to the third lumbar skeletal muscle mass index （L3 SMI）， the patients were divided into sarcopenia group and non-sarcopenia group. Nutritional risk screening， anthropometric measurements， and blood biochemical tests were performed for the patients to identify the influencing factors for sarcopenia. The patients were followed up for 36 — 48 months， and survival status and complications were compared between the two groups. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the chi-square test and the Mann-Whitney U rank sum test were used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for sarcopenia， and univariate and multivariate Cox regression analyses were used to investigate the risk factors for the prognosis of patients with WD-related liver cirrhosis. The Kaplan-Meier survival curve was plotted， and the Log-rank test was used for comparison between groups. ResultsAmong the 140 patients with WD-related liver cirrhosis， 53 （37.9%） developed sarcopenia， with significantly lower body mass index （BMI） and L3 SMI than the patients without sarcopenia （t=10.550 and 3.982， both P<0.001）. The multivariate Logistic regression analysis showed that age （odds ratio ［OR］=2.243， 95% confidence interval ［CI］： 1.196 — 4.208， P=0.012）， sex （OR=0.450， 95%CI： 0.232 — 0.872， P=0.018）， BMI （OR=0.126， 95%CI： 0.089 — 0.294， P<0.001）， and hepatic encephalopathy （OR=8.367， 95%CI： 2.423 — 28.897， P<0.001） were the main influencing factors for sarcopenia in patients with WD-related liver cirrhosis. Compared with the non-sarcopenia group， the sarcopenia group had significantly higher mortality rate （χ²=6.158， P=0.019） and significantly higher incidence rates of infection （χ²=8.008， P=0.040）， recurrent abdominal/pleural efflux （χ²=17.742， P<0.001）， and hepatic encephalopathy （χ²=4.338， P=0.039）. The multivariate Cox regression analysis showed that sarcopenia （hazard ratio ［HR］=4.685， P=0.002） and hepatic encephalopathy （HR=19.156， P<0.001） were independent risk factors for death in patients with WD-related liver cirrhosis. The Kaplan-Meier survival curve analysis showed a significant reduction in survival rate in the patients with sarcopenia （P=0.003）. ConclusionSarcopenia is one of the manifestations of malnutrition in patients with WD-related liver cirrhosis， which increases the risk of mortality and other complications and has an adverse effect on prognosis. There is an increased risk of sarcopenia in male patients or patients with hepatic encephalopathy， a lower level of BMI or an older age.

OBJECTIVE To study the clinical efficacy of Professor Li Bingmao's Tongfu Xiere Quyu Shuli Prescription in the treatment of patients with functional dyspepsia(FD)of spleen and stomach damp-heat and qi stagnation and blood stasis type.METH-ODS A total of 206 patients with functional dyspepsia of spleen and stomach damp-heat and qi stagnation and blood stasis type diag-nosed by Hengshui People's Hospital were included in the study and randomly divided into a study group and a control group with 103 cases in each group.During the treatment,3 cases dropped out in each group.The control group adopted the conventional Western medicine treatment plan for functional dyspepsia(mosapride+rabeprazole),and the study group took Tongfu Xiere Quyu Shuli Pre-scription on the basis of the treatment of the control group.The treatment course of both groups was 4 weeks.The traditional Chinese medicine(TCM)syndrome scores,psychological status[self-rating anxiety scale(SAS),self-rating depression scale(SDS),and quality of life[Nepean dyspepsia life quality index(NDLQI)of the two groups of patients before and after treatment were observed and the clinical efficacy was evaluated;serum motilin(MTL),ghrelin,gastrin(GAS),corticotropin-releasing hormone(CRH)and pep-sinogen(PG Ⅰ,PG Ⅱ)were measured by enzyme-linked immunosorbent assay;changes in gastric motility indexes were analyzed by electrogastrogram analyzer;changes in intestinal flora were detected by instillation method.The occurrence of adverse reactions in the two groups of patients was monitored during treatment.RESULTS After treatment,the TCM syndrome scores of the two groups were significantly reduced(P<0.05,P<0.01),and the score in the study group was lower than that in the control group(P<0.01).The total effective rate of the study group was significantly higher than that in the control group(P<0.01).After treatment,the expression levels of MTL,Ghrelin,GAS,PG Ⅰ and PG Ⅱ in the two groups increased,and CRH decreased,and the improvement degree of the study group was better than that of the control group(P<0.01).After treatment,the main frequency and slow wave percentage of the electrogastrogram increased in the two groups,and the study group was better than that of the control group(P<0.01).After treat-ment,the number of bifidobacteria and lactobacilli in the two groups increased,and the number in the study group was greater than that in the control group,while the number of enterobacteria,enterococci and yeast decreased,and the number in the study group was less than that in the control group(P<0.01).There was no significant difference in adverse reactions between the two groups(P>0.05).CONCLUSION Tongfu Xiere Quyu Shuli Prescription is effective in the treatment of FD patients with spleen and stomach damp-heat syndrome,and can improve FD clinical symptoms,quality of life,anxiety and depression symptoms,regulate gastrointesti-nal hormone expression levels,gastric motility and intestinal flora expression,and does not increase adverse reactions,and is safe and reliable.

Objective:To study the application effect of the Hazard Analysis and Critical Control Point(HACCP)system in risk assessment and dynamic management of operational safety of medical equipment in surgery rooms.Methods:Based on the HACCP principle,hazard analysis and risk assessment were conducted on the operational safety of equipment in surgery room,and the critical control points were determined,and measures of monitor and management were formulated to conduct whole-process dynamic management for equipment in surgery room.A total of 120 medical equipment in use in the surgery room of Shaanxi Provincial Cancer Hospital from January 2022 to January 2024 were selected.According to random number table method,they were divided into conventional management mode group(60 equipment that received conventional management mode)and dynamic management mode group(60 equipment that received the mode of risk assessment and dynamic management based on HACCP system for operational safety of medical equipment in surgery rooms)to receive different managements.The effect,operational quality,the score of management standardization,and management level for equipment in managing and controlling risk of safety of equipment were compared between two management modes.Results:The average pressure-related injury,electrical injury,extravasation of body fluid,and incidence of unqualified cleaning and disinfection of equipment in the dynamic management mode group were respectively(3.01±1.01)%,(2.65±0.78)%,(1.65±0.64)%and(1.15±0.16)%,all of which were lower than those in the conventional management mode group,and the differences were statistically significant(t=16.311,13.434,12.018,12.629,P<0.05).The average utilization rate,cost-benefit amplification and social benefit amplification of the equipment in the dynamic management mode group were respectively(95.36±2.87)%,(7.98±1.32)%and(10.68±2.36)%,all of which were higher than those in the conventional management mode group,and the average operating rate in the dynamic management mode group was(9.87±1.54)%,which was lower than that in the conventional management mode group,and the differences of the above indicators were significant(t=7.657,15.567,10.354,12.466,P<0.05).The scores of the standard degrees of use and operation,disinfection and sterilization,operation and maintenance,and repairing fault of equipment in the dynamic management mode group were higher than those in the conventional management mode group,and the differences of the above data between two groups were statistically significant(t=16.289,11.415,13.396,9.420,P<0.05),respectively.The rate of standard placement,the rate of reasonable recording and integrity rate of equipment in the dynamic management mode group were higher than those in the conventional management mode group,and the failure rate was lower than that of the conventional management mode group,and the differences of the above indicators between the two groups were statistically significant(x2=6.708,7.070,8.491,13.333,P<0.05).Conclusion:The risk assessment and dynamic management based on HACCP system for operational safety of medical equipment in surgery room can improve the management effect for equipment in surgery room,and reduce the operational risk of equipment,and realize the whole-process management and control for medical equipment in surgery room.

Objective To analyze the relationship between abnormal expression of serum neurohemoglobin(NGB)and myelin basic protein(MBP)and the cerebral neurodevelopment of neonates with hypoxic-ischemic encephalopathy(HIE).Methods A total of 89 preterm infants with HIE admitted in the hospital between January 2023 and March 2024 were selected as the observation group,and 60 preterm infants without HIE during the same period were selected as the control group.Serum levels of MBP,NGB and secretagogues in two groups were detected,and the neonates amplitude integration electroencephalogram score was evaluated.The neurological function of neonates was evaluated using 20 items of Neonatal Behavioral Neurological As-sessment(NBNA).The correlation test and diagnostic value were evaluated using Spearman method and re-ceiver operating characteristic(ROC)curve.Results The serum levels of NGB,MBP and secretagogue in the ob-servation group were higher than those in the control group(P<0.05),and the amplitude integration electroencepha-logram score was lower than that in the control group(P<0.05).The serum MBP,NGB and secretagogue levels in the mild,moderate,and severe groups increased sequentially(P<0.05),NBNA score and amplitude integration e-lectroencephalogram score decreased sequentially(P<0.05).The levels of NGB,MBP and secretagogue were the risk factors affecting NBNA score(P<0.05),and the amplitude integration electroencephalogram score was a protective factor affecting NBNA score(P<0.05).The area under the curve of NGB and MBP in diag-nosing HIE was greater than 0.8,which had high application value.Conclusion Serum NGB and MBP levels are closely related to the severity of HIE,and have certain connection with NBNA score.Elevated levels of NGB and MBP in neonates with HIE may be related to the body's stress response to nerve damage,which could reflect to some extent the brain nerve function damage in with HIE.

Objective:To explore the method for selecting characteristic prices of Chinese patent medicines based on informa-tion entropy theory.It involves analyzing the connotative differences among various price indicators and utilizing information entropy metrics to validate the scientific rigor of characteristic price selection so as to optimize the pricing model for Chinese patent medi-cines and improve the accuracy of price evaluation.Methods:A correlation analysis and information entropy calculation are con-ducted on the median price of the smallest preparation unit,average daily cost,and average course cost of TCM.It compares the information diversity and uncertainty of different pricing indicators.Results:The average daily cost exhibits the highest information diversity and uncertainty among all the pricing indicators examined.Conclusion:It is recommended that the average daily cost be used as the dependent variable for characteristic prices in TCM pricing research.This choice plays an important role in optimizing TCM pricing models and enhancing the accuracy of price evaluation.

Objective:To establish a scientific,systematic,and objective indicator system for the characteristic price variables of Traditional Chinese Patent Medicines(TCPM),providing a reference framework for the pricing mechanism of TCPM.Methods:The brainstorming method was initially used to screen related variable indicators.The Nominal Group Technique(NGT)and Delphi methods were applied to gather expert opinions,and SPSS 28.0 was employed for data statistical analysis.It led to the development of a TCPM characteristic price variable indicator system consisting of 6 dimensions,14 characteristic variables and 26 measurement indicators.Results:The authority coefficient of the experts exceeded 0.7,indicating the representativeness of the results.Expert opinions were generally concentrated.Based on the collected opinions and statistical analysis,the scope of selected TCPM characteristic price variables was preliminarily established.Conclusion:The TCPM characteristic price variable indicator system was initially developed.However,due to the complexity of the pricing mechanism and divergent expert opinions,further qualitative and quantitative research methods,along with a dynamic adjustment mechanism,are needed to verify and refine the system.

Purpose To evaluate the application value of CE-Boost technology in head and neck CT angiography(CTA)with low tube voltage,low contrast agent dosage and low injection rate.Materials and Methods A prospective study was conducted on patients who underwent head and neck CTA at Ji'nan People's Hospital Affiliated to Shandong First Medical University from September to December 2023.Using block randomization,patients were divided into group A(n=30)and group B(n=30).Group A underwent conventional scanning with 120 kV tube voltage,50 ml iodinated contrast agent and 5.0 ml/s injection rate;while group B underwent scanning with 100 kV tube voltage,30 ml iodinated contrast agent and 3.0 ml/s injection rate.CE-Boost images(group B2)were generated by performing flexible subtraction between the enhanced images of group B(group B1)and non-contrast images.CT values,noise,signal-to-noise ratio and contrast-to-noise ratio of major vessels were measured and calculated.Subjective image quality was assessed using a 5-point scale.Vascular CT values,noise,signal-to-noise ratio,contrast-to-noise ratio,subjective scores and radiation dose were compared among the three groups.Results No significant differences in noise were observed among group A,B1 and B2(all P>0.05).The aortic arch CT values,signal-to-noise ratio and contrast-to-noise ratio in group B2 were significantly higher than those in group B1 and A(all P<0.05),while group B1 exhibited significantly lower values than group A(all P<0.05).For other vessels,group B2 demonstrated significantly higher CT values,signal-to-noise ratio and contrast-to-noise ratio than group B1(all P<0.05),but no significant differences were found compared with group A(all P>0.05).Subjective scores were significantly higher in group A[5(5,5)point]and group B2[5(5,5)point]than in group B1[4(3,4)point](Z=-4.790,-4.564,both P<0.001),with no significant difference between groups A and B2(Z=-1.076,P=0.163).Group B reduced iodine intake and injection rate by 40%compared with group A(iodine intake:11.1 g vs.18.5 g;injection rate:3.0 ml/s vs.5.0 ml/s)and achieved a 30%reduction in effective radiation dose[(1.02±0.95)mSv vs.(1.44±1.66)mSv,t=12.217,P<0.001].Conclusion For patients with body mass index<28 kg/m2,CE-Boost combined with 100 kV tube voltage,30 ml iodinated contrast agent and 3.0 ml/s injection rate in head and neck CTA significantly reduces radiation dose,iodine load and injection rate while maintaining image quality.

ObjectiveTo construct an intelligent model for literature screening， retrieval， and data extraction with a systematic review of coronary heart disease syndromes as an example， so as to improve the efficiency of evidence-based Chinese medicine research. MethodsBased on China National Knowledge Infrastructure （CNKI）， VIP and Wanfang Data Resource System， the articles related to coronary heart disease syndrome research published from January 1， 2000 to December 31， 2023 were retrieved. Automated tools were used to batch retrieve paper metadata. Using text similarity algorithms， papers were merged， deduplicated， and subjected to preliminary screening based on titles and abstracts. Further screening was performed using object detection and image processing technologies on the full texts and statistical tables. Natural language processing （NLP） techniques and pre-trained models were applied to extract information. ResultsThe initial search retrieved 56 255 coronary heart disease syndrome-related articles. By artificial intelligence-assisted preliminary and secondary screening， the manual verification scope was narrowed to 1075 articles. Ultimately， 646 coronary heart disease syndrome related studies were included manually. With accuracy verification showing over 90% consistency in semantic recognition and element decomposition processes， we achieved data extraction and standardization processing for both basic literature information and 38 syndrome element statistics. ConclusionBy incorporating natural language processing， pre-trained models， artificial intelligence image processing and other technologies， this study enabled efficient retrieval， screening and standardized data extraction of Chinese medicine research literature.

Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.
