Journal of Apoplexy and Nervous Diseases 2025;42(4):306-309
Objective To investigate the features of non-motor symptoms and transcranial substantia nigra ultrasound in essential tremor (ET). Methods General data were collected from 50 patients with ET and 50 healthy controls,and non-motor symptom scales and transcranial nigra sonography (TCS) were used for assessment. The t-test,the non-parametric test,and the chi-square test were used for comparison of general data,scale assessment results,and TCS findings between the two groups. Results There were significant differences between the ET group and the healthy control group in the total scores of NMSS,MoCA,HAMA,HAMD,PSQI,ESS,and FSS and the incidence rates of cognitive impairment,moderate or severe anxiety,poor sleep,and daytime sleepiness,while there were no significant differences in the incidence rates of moderate or severe depression and fatigue between the two groups. There were no significant differences between the two groups in terms of “hyperechoic area of the left side” “hyperechoic area of the right side” “hyperechoic area of both sides” “S/M value” “the number of cases with a hyperechoic area of >0.2 cm2 for at least one side” “the number of cases with an S/M ratio of >7%” and “the number of cases with positive TCS results”. Conclusion Compared with healthy controls,ET patients are more susceptible to cognitive impairment,anxiety,depression,poor sleep quality,daytime sleepiness,and fatigue,and the non-motor symptoms of ET should be taken seriously in clinical practice. TCS examination has a relatively low diagnostic value in ET patients and healthy individuals.

Background::Hepatic ischemia-reperfusion injury (HIRI) remains a common complication during liver transplantation (LT) in patients. As a key downstream effector of the Hippo pathway, Yes-associated protein (YAP) has been reported to be involved in various physiological and pathological processes. However, it remains elusive whether and how YAP may control autophagy activation during ischemia-reperfusion.Methods::Human liver tissues from patients who had undergone LT were obtained to evaluate the correlation between YAP and autophagy activation. Both an in vitro hepatocyte cell line and in vivo liver-specific YAP knockdown mice were used to establish the hepatic ischemia-reperfusion models to determine the role of YAP in the activation of autophagy and the mechanism of regulation. Results::Autophagy was activated in the post-perfusion liver grafts during LT in patients, and the expression of YAP positively correlated with the autophagic level of hepatocytes. Liver-specific knockdown of YAP inhibited hepatocytes autophagy upon hypoxia-reoxygenation and HIRI ( P <0.05). YAP deficiency aggravated HIRI by promoting the apoptosis of hepatocytes both in the in vitro and in vivo models ( P <0.05). Attenuated HIRI by overexpression of YAP was diminished after the inhibition of autophagy with 3-methyladenine. In addition, inhibiting autophagy activation by YAP knockdown exacerbated mitochondrial damage through increasing reactive oxygen species ( P <0.05). Moreover, the regulation of autophagy by YAP during HIRI was mediated by AP1 (c-Jun) N-terminal kinase (JNK) signaling through binding to the transcriptional enhanced associate domain (TEAD). Conclusions::YAP protects against HIRI by inducing autophagy via JNK signaling that suppresses the apoptosis of hepatocytes. Targeting Hippo (YAP)-JNK-autophagy axis may provide a novel strategy for the prevention and treatment of HIRI.

Objective To conduct basic research on the structure and function of the heart in cynomolgus monkeys older than 10 years to provide data for animal selection in elderly disease research.Methods A total of 144 cynomolgus monkeys>10 years old were selected as research subjects,including 37 females and 66 males in the 10~15 years group,and 21 females and 20 males in the 16~20 years group.Basic data on cardiac structure and function in middle-aged and elderly cynomolgus monkeys were obtained through comparative analysis of general indicators(body mass index,blood pressure,and heart rate),blood biochemical indicators(blood glucose,blood lipids,and ion indicators),and cardiac structure and function indicators.Results General indicators for the 10~15 years and 16~20 years groups were compared.As age increased,the blood pressure and heart rate of female and male monkeys increased,and there was a significant difference in blood pressure changes between male monkeys.A comparison of two sets of blood biochemical indicators showed that,as age increased,blood glucose,triglycerides,total cholesterol,low-density lipoprotein cholesterol,blood calcium,blood sodium,and blood potassium increased,while lactate dehydrogenase decreased,in female and male monkeys.Among these,blood glucose,triglycerides(males),total cholesterol,high-density lipoprotein cholesterol(males),low-density lipoprotein cholesterol(males),blood calcium,blood sodium,blood potassium,and lactate dehydrogenase showed significant changes.A comparison of cardiac contractile function between the two groups showed that,as age increased,the anterior and posterior diameters of the left atrium significantly decreased in both female and male monkeys.Female monkeys showed a significant decrease in the interventricular septal end systolic diameter,left ventricular end diastole and systolic diameters,left ventricular end diastolic and systolic volumes,and left ventricular mass index,while no significant changes were seen in male monkeys.A comparison of diastolic function between the two groups showed that,as age increased,the late diastolic velocity of the mitral valve decreased significantly in male monkeys,while the early diastolic velocity of the left ventricular sidewall increased significantly in female monkeys.Correlation analysis was conducted between the metabolic indicators and the cardiac structure and function indicators of female and male monkeys.The correlations between metabolic indicators and cardiac structure and function indicators were weak in female monkeys,for which the maximum absolute Γ value did not exceed 0.39.However,the correlations between metabolic indicators and cardiac structure and function indicators were relatively strong in male monkeys,for which the maximum absolute Γ value reached 0.66.Conclusions Based on ultrasound analysis combined with metabolic indicators,the heart function of cynomolgus monkeys was studied,and basic data related to the structure and function of the heart in middle-aged and elderly cynomolgus monkeys were obtained.As age increased,blood glucose and lipid indicators increased in cynomolgus monkeys,while cardiac systolic and diastolic functions show a downward trend,similar to changes in middle-aged and older adult human populations.These data provide support for animal selection in research on age-related diseases related to heart function.

The comprehensive detection and identification of active ingredients in complex matrices is a crucial challenge.Liquid chromatography coupled with high-resolution mass spectrometry(LC-HRMS)is the most prominent analytical platform for the exploration of novel active compounds from complex matrices.However,the LC-HRMS-based analysis workflow suffers from several bottleneck issues,such as trace content of target compounds,limited acquisition for fragment information,and uncertainty in interpreting relevant MS2 spectra.Lycibarbarspermidines are vital antioxidant active ingredients in Lycii Fructus,while the reported structures are merely focused on dicaffeoylspermidines due to their low content.To comprehensively detect the new structures of lycibarbarspermidine derivatives,a"depict"strategy was developed in this study.First,potential new lycibarbarspermidine derivatives were designed according to the biosynthetic pathway,and a comprehensive database was established,which enlarged the coverage of lycibarbarspermidine derivatives.Second,the polarity-oriented sample prep-aration of potential new compounds increased the concentration of the target compounds.Third,the construction of the molecular network based on the fragmentation pathway of lycibarbarspermidine derivatives broadened the comprehensiveness of identification.Finally,the weak response signals were captured by data-dependent scanning(DDA)followed by parallel reaction monitoring(PRM),and the efficiency of acquiring MS2 fragment ions of target compounds was significantly improved.Based on the integrated strategy above,210 lycibarbarspermidine derivatives were detected and identified from Lycii Fructus,and in particular,170 potential new compounds were structurally characterized.The integrated strategy improved the sensitivity of detection and the coverage of low-response components,and it is expected to be a promising pipeline for discovering new compounds.

In recent years, the number of lung surgeries has increased year by year, and the number of patients with postoperative cough has also increased gradually. Chronic cough after lung surgery seriously affects patients' quality of life and surgical outcome, and has become one of the clinical problems that clinicians need to solve. However, there is currently no guideline or consensus for the treatment of chronic cough after lung surgery in China, and there is no standardized treatment method. Therefore, we searched databases such as PubMed, Web of Science, CNKI, and Wanfang databases ect. from 2000 to 2023 to collected relevant literatures and research data, and produced the first expert consensus on chronic cough after lung surgery in China by Delphi method. We gave 11 recommendations from five perspectives including timing of chronic cough treatment, risk factors (surgical method, lymph node dissection method, anesthesia method), prevention methods (preoperative, intraoperative, postoperative), and treatment methods (etiological treatment, cough suppressive drug treatment, traditional Chinese medicine treatment, and postoperative physical therapy). We hope that this consensus can improve the standardization and effectiveness of chronic cough treatment after lung surgery, provide reference for clinical doctors, and ultimately improve the quality of life of patients with chronic cough after lung surgery.

Cold and heat belong to the eight-principal syndrome differentiation of traditional Chinese medicine, which can reflect the rise and fall of Yin and Yang in the body and the Yin and Yang nature of the disease. At present, traditional Chinese medicine has an inconsistent understanding of cold and heat in acute coronary syndrome. The emphasis on pathogenic factors of cold and heat is biased, and the elements of cold and heat syndrome are not fully reflected in the scale. Therefore, the literature has been reviewed from the perspectives of etiology, pathogenesis, symptom elements, and test signs with drugs. From the perspective of etiology, both cold evil and heat evil can increase the risk of acute coronary syndrome. It was previously believed that acute coronary syndrome occurs frequently in cold climates such as winter and spring. Based on this understanding, hot weather can also induce acute coronary syndrome, and different temperatures have different effects on patients of different ages and with different underlying diseases. In addition, artificial pathogenic factors such as excessive consumption of cold food and refrigeration air conditioners were added. From the perspective of pathogenesis, on the basis of the traditional ''asthenia in origin and asthenia in superficiality'' and ''phlegm stagnation'', it is found that Yin-cold and fire-heat can both cause paralysis of the heart chakra and pain induced by the blockage. The pathogenesis of acute coronary syndrome characterized by heat stagnation and coldness featuring heartburn should be distinguished from gastroesophageal reflux disease. Moreover, the pathogenesis of Yin cold coagulation and pulse stagnation and wind obstruction are different. The acute coronary syndrome is in line with the wind characteristics of frequent changes and can be treated with wind medicine. From the perspective of syndrome elements, the syndrome elements such as cold condensation, heat accumulation, and toxicity are analyzed, and the use of basic syndrome elements and their combination forms facilitates clinical and scientific research. In addition, according to the test sign with the drug, it can be seen that the attributes of cold and heat of traditional Chinese medicine prescriptions for acute coronary syndrome can be explained according to the temperature-sensitive transient receptor potential (TRP) ion channel, thus proving the pathogenesis of cold and heat of acute coronary syndrome.

AIM: To investigate the clinical value of serum vitamin A(Vit A)and basic fibroblast growth factor(bFGF)levels predicting retinopathy of prematurity(ROP).METHODS: Prospective cohort studies. A total of 411 premature or low birth weight infants with gestational age less than 37 wk or birth weight less than 2 500 g who were delivered in Hainan Branch, Shanghai Children's Medical Center Affiliated to Shanghai Jiao Tong University School of Medicine from January 2020 to December 2022 were selected as subjects. The Vit A and bFGF levels in peripheral blood were detected at 7 d and 35 d after birth, respectively.RESULTS: A total of 392 premature infants or low birth weight infants completed clinical study, including 51 cases in stage 1-2 ROP group, 23 cases in stage 3-5 ROP group and 318 cases in the group without ROP. At 7 d postnatal, the serum Vit A(0.44±0.17 μmol/L)and bFGF(0.53±0.16 ng/L)levels in stage 1-2 ROP group were lower than those in the group without ROP(0.50±0.12 μmol/L and 0.63±0.15 ng/L; all P<0.05). The serum Vit A(0.34±0.18 μmol/L)and bFGF(0.44±0.18 ng/L)levels in stage 3-5 ROP group were lower than those in the group without ROP(P<0.05). The serum Vit A and bFGF levels in stage 3-5 ROP group were lower than those in stage 1-2 ROP group(P<0.05). At 35d postnatal, the serum Vit A(0.33±0.19 μmol/L)and bFGF(0.39±0.19 ng/L)levels in stage 3-5 ROP group were lower than those in stage 1-2 ROP group(0.43±0.16 μmol/L and 0.48±0.17 ng/L; all P<0.05). According to the ROC curve drawn by serum Vit A, the AUC value was 0.853, the maximum Youden index was 0.68, the best sensitivity was 73%, and the best specificity was 95%. According to the ROC curve drawn by serum bFGF, the AUC value was 0.828, the maximum Youden index was 0.58, the best sensitivity was 90%, and the best specificity was 68%. According to the ROC curve drawn by serum Vit A combined with bFGF, the AUC value was 0.917, the maximum Youden index was 0.70, the best sensitivity was 70%, and the best specificity was 100%.CONCLUSION: Serum Vit A and bFGF levels are sensitive and effective indicators for predicting ROP. If the serum Vit A or bFGF levels are lower in premature infants or low birth weight infants, it may indicate the higher probability of ROP and its pathological stages. In addition, the clinica value of serum Vit A combined with bFGF in the diagnosis of ROP is higher than that of Vit A or bFGF alone, and the misdiagnosis rate is reduced.
