ObjectiveTo investigate the non-suicidal self-injury （NSSI） behaviors in adolescents with depressive disorder， analyze related influencing factors， and provide theoretical basis and reference for the prevention and treatment of NSSI. MethodsAccording to DSM-5 criteria， 95 depressive adolescents were divided into two groups： one with NSSI （NSSI group） and one without NSSI （nNSSI group）. All patients were assessed with Adolescent Non-suicidal Self-injury Assessment Questionnaire （ANSAQ）， Self-Rating Depression Scale （SDS）， Self-Rating Anxiety Scale （SAS）， Simplified Coping Style Questionnaire （SCSQ）， Experiences in Close Relationships-Relationship Structures Scale （ECR-RS）， and Childhood Trauma Questionnaire-Short Form （CTQ-SF）. The inter-group differences were compared. The influencing factors of NSSI were analyzed by using binary logistic regression. ResultsOf the 95 depressive adolescents， 59 cases of NSSI were identified， with a detection rate of 62.11%. NSSI group had higher scores than nNSSI group on SDS， SAS， negative coping style， paternal attachment anxiety， maternal attachment anxiety and avoidance， CTQ-SF total score， emotional neglect， physical neglect， emotional abuse， and sexual abuse （all P<0.05）. Binary logistic regression analysis showed that anxiety， negative coping style， maternal attachment avoidance and emotional abuse increased the risk of NSSI among adolescents with depressive disorders （all P< 0.05）. ConclusionsAdolescents with depression have a high incidence of NSSI behaviors， which is related to anxiety， negative coping style， maternal attachment avoidance and emotional abuse. In addition to improving patients' depression and anxiety in clinical setting， attention should also be paid to patients' coping styles， parent-child relationship and childhood trauma to reduce the occurrence of NSSI behaviors.

ObjectiveTo study the characteristics of the five tones of Parkinson's disease （PD） patients based on the theory of "five-viscera phonology"， and provide references for the syndrome differentiation and treatment of PD. MethodsA total of 272 cases of PD patients were collected as the PD group， and 240 individuals， including patient family members and hospital staff， were recruited as the control group. The 25-tone analyzer was used to collect the five-tone characteristics of both PD patients and control group participants. The participants were then stratified into three age groups， 41~55， 56~70， and 71~85 years old， and categorized by gender （male and female） for analysis. The frequency and composition ratio of the five tones were analyzed for both groups across the different age ranges and genders. Additionally， the average voice frequency of each participant was calculated to compare differences between groups， stratified by age range and gender. ResultsIn the 41~55 and 56~70 age groups， male participants in the PD group and the control group exhibited the highest frequency of Yu （羽） tone， with the PD group showing a significantly higher composition ratio of Yu tone compared to the control group （P＜0.05）； for males in the 56~70 age group， the composition ratios of Shang （商） and Zhi （徵） tone in the PD group were lower than those in the control group （P＜0.05）. For males in the 71~85 age group， both the PD group and the control group had the highest frequency of Yu tone， but there was no statistically significant difference in the composition ratios of the five tones between groups （P＞0.05）. For female participants in the PD group across all age groups， Yu tone was the most frequent， whereas for the control group， Jue （角） tone was the most frequent in all age groups， and the composition ratio of Yu tone in the PD group was significantly higher than that in the control group across all age groups （P＜0.05）； in the 56~70 age group， the composition ratio of Jue tone was lower in the PD group compared to that in the control group （P＜0.05）. Regarding voice frequency， males in the PD group aged 41~55 and 56~70 had higher voice frequency than those in the control group of the same age range， and similarly， females in the PD group aged 56~70 and 71~85 had higher voice frequency than their counterparts in the control group （P＜0.05）. ConclusionPD patients have a voice with a higher frequency and an increased proportion of Yu tone in their five-tone distribution. According to the theory of five-viscera phonology， PD patients may have disease mechanism of kidney essence deficiency.

Chronic liver diseases with common causes including viral infections， alcohol abuse， and autoimmune diseases. Alkaloids， as a class of plant-derived compounds， have shown significant potential in regulating chronic liver diseases. Recent studies have shown that alkaloids are able to exert a therapeutic effect on chronic liver diseases through multiple pathways. These compounds have a regulatory effect on key pathological processes such as liver fibrosis， inflammatory response， oxidative stress， and cell apoptosis， and they also regulate the metabolic homeostasis of hepatocytes by modulating multiple signaling pathways， thereby playing a role in regulating chronic liver diseases. This article reviews the role and mechanism of alkaloids in the treatment of chronic liver diseases， in order to provide new ideas and directions for the treatment of chronic liver diseases.

Objective To explore the influencing factors of coronary artery lesion severity in patients with acute coronary syndrome (ACS). Methods Clinical data of ACS patients admitted to Zhongshan Hospital, Fudan University from December 2017 to December 2019 were consecutively collected. The modified Gensini score was used to assess the severity of coronary artery lesions. Univariate and multivariate linear regression analyses were performed to identify independent factors associated with coronary artery lesion severity. Results A total of 1 689 ACS patients were included, with an average age of (64.04±11.45) years; 1 353 (80.11%) were male, and the mean modified Gensini score was (8.12±4.03). Multivariate linear regression analysis revealed that sex (β＝0.97, P＝0.001), age (β＝0.03, P＝0.021), estimated glomerular filtration rate (eGFR; β＝－0.03, P＜0.001), low-density lipoprotein cholesterol (LDL-C; β＝0.58, P＜0.001), apolipoprotein A1 (Apo A1; β＝－1.28, P＝0.012), lipoprotein(a) [Lp(a); β＝0.001, P＝0.033], and glycated hemoglobin A_1C (HbA_1C; β＝0.45, P＜0.001) were independent influencing factors of the modified Gensini score. Conclusions Metabolic indicators, including Apo A1, LDL-C, HbA_1C, and Lp(a), may serve as risk factors for coronary artery lesion severity in ACS patients, with Apo A1 demonstrating the strongest impact.

OBJECTIVE To provide practical basis and policy recommendations for improving the pharmacovigilance （PV） system construction in medical institutions across China. METHODS A questionnaire survey was conducted using a mixed sampling strategy of “online random sampling+offline supplementary sampling” to distribute questionnaires among pharmaceutical professionals in tertiary medical institutions nationwide. The questionnaire covered aspects such as the construction of PV systems， job position settings， information system support， operational practices， and multi-stakeholder collaboration. The data were analyzed using descriptive methods and SPSS 20.0 statistical software. RESULTS A total of 70 valid questionnaires were collected from 66 medical institutions， primarily Class A tertiary hospitals. The survey found that 90.00% had designated PV personnel and 74.29% routinely conducted PV activities. However， there were notable disparities in resource allocation and information system capacity， with less than 50% of the institutions conducting post-marketing drug re-evaluation. PV activities were primarily focused on the collection and reporting of adverse drug reactions， with limited capabilities in signal detection and risk assessment. CONCLUSIONS Among the surveyed tertiary hospitals， PV systems have begun to take shape. However， challenges persist in terms of system establishment， resource allocation， risk assessment， and inter-organizational coordination. Policy efforts should focus on strengthening regulatory frameworks， improving information sharing mechanisms， enhancing professional training， and strengthening collaboration between hospitals and market authorization holders to ensure the effective implementation of PV in medical institutions.

Conclusion Curcumol exerts ameliorative effects on hepatic fibrosis by modulating mitochondrial hyperautophagy mediated by the PINK1/Parkin signaling pathway, and promoting hepatic stellate cell apoptosis.

Diabetic cardiomyopathy(DCM)is a unique myocardial disease caused by diabetes mellitus,which can increase the risk of heart failure and death,and is one of the main causes of death of diabetes mellitus patients worldwide.Although the research on the pathogenesis of DCM has made great progress,it has not yet been fully clarified.Many studies have shown that long noncoding RNAs(lncRNAs)can interact with microRNAs(miRNAs)as competitive endogenous RNAs(ceRNAs),participate in the regulation of gene expression,and then affect the development of DCM.This article gives an overview of lncRNAs and its biological functions as well as ceRNA hypothesis,and focuses on the role of lncRNAs as ceRNAs in regulating the occurrence and development of DCM.

Objective:To develop a virtual reality (VR) exercise rehabilitation system for home-based patients with spinal cord injury, and test patients' acceptance and experience.Methods:The VR exercise rehabilitation system for home-based patients with spinal cord injury was developed by a multidisciplinary team based on the home rehabilitation needs, evidence, and clinical experience of spinal cord injury patients, and further improved after recommendations from experts and patients. From February to July 2024, convenience sampling was used to select 148 patients with spinal cord injuries admitted to the Department of Spinal Cord and Neurological Function Reconstruction at the China Rehabilitation Research Center. Acceptance Questionnaire was used to investigate patients' acceptance of the system. Thirteen patients with spinal cord injuries were selected for semi-structured interviews to explore the themes of their experiences using VR exercise rehabilitation system for home-based patients with spinal cord injury.Results:A VR exercise rehabilitation system for home-based patients with spinal cord injury was developed, which includes four aspects of personal profile, personal assessment, training selection, and care knowledge. The total acceptance score of this system among 148 patients was (87.69±1.59). Through semi-structured interviews, three themes were identified involving excellent experience, expectation of rehabilitation effects, satisfaction with functionality and hope for continuous system updates.Conclusions:The design of VR exercise rehabilitation system for home-based patients with spinal cord injury is scientifically reasonable, which can further verify the rehabilitation effect of the system.

Objective:To investigate the effect of high-dose vitamin B6 on stress-induced liver cell death in rats with severe trauma and its possible mechanism.Methods:Thirty-two male SD rats were selected and divided into sham surgery group, sham surgery+B6 group, trauma group, and trauma+B6 group by using a random number table, with 8 rats in each group. Rat models of severe trauma were established by inducing abdominal wall injury, bilateral femoral fractures, unilateral cranial injury, and withdrawal of 4 ml blood from the femoral artery. The sham surgery+B6 group and trauma+B6 group were treated with saline solution plus high-dose vitamin B6, while the sham surgery group and trauma group with infusion of saline solution only. At 36 hours after injury, rat liver tissues were collected for the following experiments: (1) the genes differentially expressed in the liver tissues of the rats of the trauma group and the trauma+B6 group were screened with next-generation sequencing, followed by an analysis of the possible involvement of cell death pathways; (2) validation was conducted to ascertain whether high-dose vitamin B6 could influence various cell death pathways in the liver cells in the sham surgery group, sham surgery+B6 group, trauma group, and trauma+B6 group: apoptosis was confirmed through terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) staining; necroptosis was verified by mixed lineage kinase domain-like protein (MLKL) immunohistochemical staining; autophagy was examined via transmission electron microscopy; ferroptosis was confirmed by detecting oxidative malondialdehyde (MDA) levels, oxidized glutathione levels, Prussian blue staining with diaminobenzidine (DAB) enhancement, transmission electron microscopy, and immunohistochemical staining for acyl-CoA synthetase long-chain family member 4 (ACSL4); (3) Biological information analyses [Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Enrichment analysis (GSEA)] were performed for biological processes and signaling pathways represented by liver tissue sequencing results of rats between the trauma group and the trauma+B6 group.Results:(1) In the liver tissues of rats, there were 344 significantly differentially expressed genes between the trauma group and trauma+B6 group, comprising 137 upregulated genes and 207 downregulated genes, of which 18 genes were associated with apoptosis, autophagy, necroptosis, ferroptosis, and pyroptosis. (2) No significant differences were found in TUNEL staining among the sham surgery group, sham surgery+B6 group, trauma group or trauma+B6 group; MLKL protein expression levels in the liver tissues after trauma were improved, of which the trauma+B6 group was lower than that of the trauma group; Electron microscopy showed that autophagic activity in the liver cells were significantly increased after trauma, which was significantly lower of the trauma+B6 group than that of the trauma group; MDA levels in the rat liver tissues were (0.20±0.05)nmol/mg, (0.17±0.07)nmol/mg, (0.69±0.11)nmol/mg and (0.52±0.07)nmol/mg in the sham surgery group, sham surgery+B6 group, trauma group, and trauma+B6 group respectively ( P<0.01), with the trauma group having the highest MDA levels and trauma+B6 group having lower MDA levels than the trauma group; Oxidized glutathione levels in the liver tissues of the four groups were (11.75±2.09)μmol/g, (11.69±1.66)μmol/g, (19.75±3.40)μmol/g, and (14.51±1.46)μmol/g respectively ( P<0.01), with the trauma group having the highest levels and trauma+B6 group having lower levels than the trauma group; Significantly increased iron deposition was observed in the liver tissues after trauma, with lower iron deposition in trauma+B6 group than the trauma group; Electron microscopy revealed significantly lower mitochondrial membrane density in the trauma+B6 group compared to the trauma group. ACSL4 protein expression level was lower in the trauma+B6 group compared to the trauma group; (3) GO, KEGG and GSEA enrichment analyses suggested that high-dose vitamin B6 may enhance cholesterol synthesis metabolism in the liver cells and alleviate oxidative stress to reduce liver cell damage and restore normal liver cell function after trauma. Conclusions:High-dose vitamin B6 attenuates stress-induced liver injury in rats with severe trauma by inhibiting the progression of necroptosis, autophagy and ferroptosis. Its molecular mechanism may be associated with enhanced hepatic cholesterol synthesis metabolism and alleviation of oxidative stress in the liver cells.

Parkinson's disease(PD)is a prevalent condition among the elderly, with its incidence increasing with age and significantly affecting the quality of life in this demographic.Given the unique characteristics of older adults, such as comorbidities, polypharmacy, and reduced sensitivity to treatment regimens, it is essential to not only focus on the efficacy of medications used in PD treatment but also to carefully evaluate the associated drug risks.This article examines a drug risk management approach for treating elderly patients with PD, emphasizing the importance of gathering comprehensive drug information, identifying potential risks associated with drug selection, procurement, storage, prescription, and dispensing, and addressing specific considerations pertinent to the elderly population.Furthermore, the article proposes management strategies aimed at standardizing risk management in the treatment of elderly patients with PD, enhancing clinical pharmacy services in this area, and promoting rational drug use among this vulnerable group.
