ObjectiveThis paper aims to use the digital muscle function assessment system Myoton PRO to assess the correlation between muscle tension，clinical characteristics， and traditional Chinese medicine（TCM） syndromes in patients with hepatolenticular degeneration ［also known as Wilson disease（WD）］. MethodsA total of 104 patients with WD accompanied by abnormal muscle tension（increased or decreased，hereinafter the same） who were hospitalized in the Brain Disease Centre of the First Affiliated Hospital of Anhui University of Chinese Medicine from April 2021 to November 2023 were selected，all of whom were subjected to TCM syndrome diagnosis and Myoton PRO for the measurement of F value of muscle tension，Goldstein， and UWDRS-N scales. The age of onset of the disease and disease duration were analyzed，and the differences and correlations of the above indexes in different TCM syndromes of WD were analyzed ResultsAmong the 104 patients with WD ，the phlegm and stasis syndrome was the most common（60 patients），followed by the damp-heat syndrome（33 patients），and the least common was the liver-kidney Yin deficiency syndrome（11 patients）. The F value of the phlegm and stasis syndrome group was higher than that of the liver-kidney Yin deficiency syndrome group and the damp-heat syndrome group（P<0.01）. The F value of the damp-heat syndrome group was higher than that of the liver-kidney Yin deficiency syndrome group（P<0.05），and the F value of the lower limbs of each group was higher than that of the upper limbs（P<0.01）. Goldstein and UWDRS-N scores of the patients in the phlegm and stasis syndrome group were higher than those in the damp-heat syndrome group and the liver-kidney Yin deficiency syndrome group（P<0.05）. There was no significant difference between the Goldstein and UWDRS-N scores of patients in the liver-kidney Yin deficiency syndrome group and the damp-heat syndrome group. Correlation analysis revealed that the age of onset and duration of the disease were positively correlated with the F values of the lower limbs（r=0.20，P<0.05，r=0.38，P<0.01）and had no significant correlation with those of the upper limbs. The F value levels of muscle tension of all limbs in the three groups of patients were positively correlated with the Goldstein and UWDRS-N scores（muscle tension of the upper limbs in the phlegm and stasis syndrome group，r=0.36，P<0.01，r=0.42，P<0.01. muscle tension of the lower limbs in the phlegm and stasis syndrome group，r=0.70，P<0.01，r=0.60，P<0.01. muscle tension of the upper limbs in the damp-heat syndrome group，r=0.64，P<0.01，r=0.53，P<0.01. muscle tension of the lower limbs in the damp-heat syndrome group，r=0.59，P<0.01，r=0.70，P<0.01. muscle tension of the upper limbs in the liver-kidney Yin deficiency syndrome group，r=0.70，P<0.01，r=0.74，P<0.01. muscle tension of the lower limbs in the liver-kidney Yin deficiency syndrome group，r=0.85，P<0.01，r=0.62，P<0.01）. Conlusion： The digital muscle function assessment system Myoton PRO can objectively evaluate the muscle tension level of patients with WD accompanied by abnormal muscle tension. This level has significant differences among different TCM syndromes and can evaluate the patient's condition to some extent.

ObjectiveTo investigate the correlation with cognitive function based on a new Kayser-Fleischer ring （K-F ring） grading method in Wilson’s disease （WD）. MethodsA total of 136 WD patients who were hospitalized in Encephalopathy Center， The First Affiliated Hospital of Anhui University of Chinese Medicine， from April 2022 to October 2023 were enrolled. All subjects underwent slit lamp examination， and the grade of K-F ring was determined according to the shape and extent of copper deposition in the cornea， whether it formed a ring or not， and whether there was a sunflower-like cloudy change in the lens. The patients were instructed to complete UWDRS， MoCA， and MMSE scale assessments， and these indicators were compared between patients with different K-F ring grades. An analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the least significant difference t-test （homogeneity of variance） or the Dunnett’s T3 test （heterogeneity of variance） was used for further multiple comparisons； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups； the chi-square test was used for comparison of categorical data between groups. The Spearman correlation analysis was used to investigate the correlation of K-F ring grade with UWDRS， MoCA， and MMSE scores. ResultsAmong the 136 patients with WD， there were 40 patients with grade 4 K-F ring， accounting for the highest proportion of 29.4%， and 14 patients with grade 0 K-F ring， accounting for the lowest proportion of 10.3%， and there were 22 patients with grade 1 K-F ring （16.2%）， 19 with grade 2 K-F ring （14%）， 25 with grade 3 K-F ring （18.4%）， and 16 with grade 5 K-F ring （11.7%）. According to the different grades of K-F ring， there was a significant increase in UWDRS score （F=22.61， P<0.001） and significant reductions in MoCA and MMSE scores （F=16.40 and 13.80， both P<0.001）. The Spearman correlation analysis showed that K-F ring grade was positively correlated with UWDRS score （r=0.67， P<0.01） and was negatively correlated with MoCA and MMSE scores in WD patients （r=-0.59 and -0.57， both P<0.01）. ConclusionThe new K-F ring grading method can determine disease severity in WD patients to a certain degree and partially reflect cognitive function and activities of daily living in such patients.

The bioactivity-guided isolation of potentially active natural products has been widely utilized in pharmaceutical discovery. In this study, by screening fungal extracts against coxsackievirus B3 (CVB3), three new aspochalasins, templichalasins A‒C (1‒3), along with six known aspochalasins (4‒9) were isolated from an active extract derived from the endophytic fungus Aspergillus templicola LHWf045. Compound 1 features a unique 5/6/5/7/5 pentacyclic ring system, while compounds 2 and 3 possess unusual 5/6/6/7 tetracyclic skeletons. Their structures were characterized through extensive spectroscopic analyses, electronic circular dichroism (ECD) calculations, and single-crystal X-ray diffraction analysis. Additionally, we demonstrated that compound 4 can be readily converted into compounds 1‒3 under mild acidic conditions and proposed a plausible mechanism for this conversion. Bioactivity evaluation of compounds 1‒9 against CVB3 revealed the inhibitory effects of all compounds against the virus. Notably, compound 9 exhibited superior antiviral activity, surpassing the commercial drug ribavirin in selectivity index (SI) value.

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 investigate the application effects of cardiac resynchronization therapy(CRT)of[left bundle optimization(LOT)]and biventricular pacing(BiV)in the patients with chronic heart failure complicating left bundle branch block.Methods The single center,prospective and non-randomized controlled study method was used.Forty-two patients with heart failure meeting CRT in this center from April 2020 to April 2022 were consecutively included.Among them,32 cases adopted the BiV-CRT(BiV-CRT group)and 10 cases adopted LOT-CRT(LOT-CRT group).The pacing-making parameters,quality of life scale(SF-36)score,6-min walk test(6-MWT),ECG QRS width(QRSd),left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF)and New York cardiac function grade(NYHA)situation were collected before surgery,after surgery immediately and in postoperative 3,6,12 months.Their complica-tions and clinical outcomes were evaluated.Results The pacing threshold value in the LOT-CRT group was stable and lower than that in the BiV-CRT group(P＜0.05);QRSd in postoperative 12 months in the LOT-CRT group was shorter than that in the BiV-CRT group[(115.0±14.3)ms vs.(133.0±14.0)ms,P＜0.05]and 6-MWT was longer than that in the BiV-CRT group[(327.0±52.8)m vs.(274.0±52.8)m,P＜0.05],and the differences were statistically significant(P＜0.05);LVEF,LVEDD,NYHA cardiac grade and SF-36 score in postoperative 12 months were improved compared with those before implantation.The rehospitaliza-tion rate of heart failure in the LOT-CRT group was lower.Conclusion LOT-CRT could obtain a narrower QRS wave and longer 6-MWT than BiV-CRT.

In recent years， enhanced recovery after surgery （ERAS） has been widely used in clinical practice， aiming to optimize perioperative management measures through evidence-based medicine and reduce the physical and mental trauma， stress reactions， and complications of surgical patients through multidisciplinary collaboration. This paper examined the clinical practice of ERAS from the perspective of medical humanities， reviewed its development and characteristics， and first pointed out that the concept of “minimal harm” laid the medical humanities foundation for ERAS. However， the concept of “minimum harm” faced ethical and realistic challenges in practice， such as differentiated cognition between benefits and non-harm， the tension between generalization and personalization， and the gap between rehabilitation continuity and family care. This paper led into the caregiving perspective of social sciences， proposed “optimal care” as a supplement to the medical humanities concept of ERAS， and introduced its connotation and practice. The combination of “minimal harm” and “optimal care” can provide theoretical guidance for medical humanistic care in ERAS and innovate the practical path of medical humanities into clinical practice.

[Objective]To investigate the efficacy of a blended instruction model which incorporated preceptorship into the clinical anatomy course at Sun Yat-sen University and improve satisfaction and performance of medical students.[Methods]The study recruited participants including 375 Chinese students aged 20-24 years old,2 anatomy professors,49 surgeons and 7 lab technicians. The students were divided into 10 teams and each team was tutored by 1 anatomy professor,2 surgeons and 1 lab technician. After the course ended,the Course Experience Questionnaire (CEQ) and Student Experience in Education Questionnaire (SEEQ) were used in the survey to measure the quality of teaching and students' overall educational experience. Students' performance scores were collected and analyzed.[Results]The response rates for CEQ and SEEQ were 60.3％ (226/375) and 54.6％ (200/375),respectively. CEQ indicated a moderate level of overall satisfaction with 7.12 out of 10. Subscales like Clear Goals,Good Teaching and Generic Skills showed moderately positive reception of the course,while subscales like Appropriate Workload and Appropriate Assessment revealed students' concerns about heavy workload and difficult exam. There was no statistically significant difference in perceptions between male and female students. The students who are more satisfied with the quality of the course are also more satisfied with the way it is taught (P<0.01). SEEQ further confirmed the universal appeal of the course,with high scores in dimensions like Learning,Enthusiasm and Individual Rapport among the students. Qualitative responses highlighted areas of improvement,such as consistent teaching methods,practical hands-on experience for the students and alignment between what was taught and tested.The students after the preceptorship introduction achieved better academic performance than before.[Conclusions]The blended instruction model incorporating preceptorship enhances the student satisfaction and performance in clinical anatomy course,and also stimulates students' learning enthusiasm and group interaction. We need further improvement in the teaching quality control,syllabus contents and course assessment for teaching of clinical anatomy.
