Parkinson's disease （PD） is a neurodegenerative disorder primarily characterized by motor dysfunction. Traditionally， its main clinical features include resting tremor， muscular rigidity， bradykinesia， and postural balance disorders. However， an increasing number of studies have shown that its non-motor symptoms （NMS） exert an even greater impact on patients' quality of life than motor symptoms， severely affecting daily functioning and increasing the burden on families and society. Among these， depression is one of the most common and most debilitating NMS， with statistics indicating that the incidence of depression among PD patients reaches as high as 40%-50%. The pathological mechanisms are complex， involving the interplay between degenerative changes in dopaminergic neurons and disruptions in emotional regulatory circuits， which poses a substantial challenge to clinical treatment. Traditional Chinese medicine （TCM）， characterized by holistic regulation and multi-target intervention， has demonstrated significant advantages in the treatment of PD and depression， offering new insights for managing PD-depression comorbidity. This study integrates research extracted from multiple databases， including PubMed， Web of Science， Google Scholar， and China National Knowledge Infrastructure （CNKI）， that investigates the potential mechanisms of PD and depression as well as TCM-based treatments for these conditions. The aim is to elucidate the shared pathological mechanisms underlying PD and depression and to explore the therapeutic potential of TCM in effectively combating PD-depression comorbidity through these shared mechanisms， thereby providing valuable insights for the development of targeted therapies.

Icodextrin peritoneal dialysis solution may produce cytotoxic α-dicarbonyl degradation products during heat sterilization, which must be monitored and controlled. The study established an o-phenylenediamine (OPD) derivatization HPLC-MS/MS method for the detection of these degradation products, enabling qualitative and quantitative analysis of α-dicarbonyl degradation products in icodextrin peritoneal dialysis solution. The results indicated that the main α-dicarbonyl degradation products in icodextrin peritoneal dialysis solution are 3-deoxyglucosone (3-DG), 3-deoxygalactosone (3-DGal), 4-deoxyglucosone (4-DG), and 3,4-dideoxyglucosone-3-ene (3,4-DGE), along with two monocarbonyl degradation products, furfural and 5-hydroxymethylfurfural. The quantitative method for 3-DG, 3-DGal, 3,4-DGE and their structural analog, glucosone, was validated. 3-DG, 3-DGal, and glucosone exhibited good linear relationships within the range of 5-150 ng/mL, while 3,4-DGE showed good linearity in the range of 1-150 ng/mL. The spiked recovery rates for all compounds were between 86.8% and 100.0%. The detection limits for glucosone, 3-DG, and 3-DGal were approximately 2.4 ng/mL, and approximately 0.5 ng/mL for 3,4-DGE. The method established in this study can accurately determine α-dicarbonyl degradation products in icodextrin peritoneal dialysis solution, providing an important basis for the quality control.

Objective To elucidate the kinetic characteristics of viral replication and transcription,an in vitro model of viral replication and transcription was established.Utilizing single-molecule magnetic tweezers technology,the dynamic process of SARS-CoV-2 RNA-dependent RNA polymerase(RdRp)during in vitro replication and transcription was investigated.Methods The force field of the single-molecule magnetic tweezer system was corrected using DNA fragments,followed by the construction of RNA fragments to explore the kinetics of RdRp replication and transcription in vitro.Results The force field calibration results were consistent with the worm-like chain model(WLC).The ssRNA strand was found to be approximately 0.3 pm longer than the dsRNA strand and could be stably extended under a 30 pN force field.The average synthesis rate of RdRp extension was determined to be 3.27 nt/s,with an average processivity of 886 nt.Conclusions By implementing force calibration in single-molecule magnetic tweezers,the real-time tracking of RdRp kinetics during the full-cycle replication-transcription process(initiation,elongation,and termination)in vitro was achieved,thereby constructing a mechanistic model of RdRp-driven nucleic acid synthesis.This study provides a basis for further investigating the kinetics of viral RdRp in physiological processes including replication,transcription,and backtracking under varied in vitro environments using single-molecule magnetic tweezers,and establishes a single-molecule manipulation framework for evaluating the effects of therapeutic compounds on viral replication-transcription processes in vitro.

Objective:To analyze and explore the selection of secondary intervention strategies for residual issues following congenital aortic valve disease surgery in children, as well as to evaluate their prognostic efficacy.Methods:A retrospective analysis was conducted on the clinical data of 41 children with residual issues after congenital aortic valve disease surgery, who were treated at the Department of Cardiovascular and Thoracic Surgery, Shanghai Children's Medical Center, between January 2013 and August 2024. Among them, 25 were male and 16 were female, with a mean age of(116.8±45.1)months and a mean weight of(40.0±20.2)kg. The mean interval for secondary intervention was(60.0±36.4)months. The residual issues included aortic valve insufficiency(20 cases), aortic valve stenosis(11 cases), and combined aortic valve insufficiency and stenosis(10 cases).Results:Secondary interventions included aortic valve repair(7 cases), mechanical valve replacement(20 cases), Ross procedure(13 cases), and Ozaki procedure(1 case). Additionally, 5 cases with left ventricular outflow tract stenosis underwent concomitant Konno surgery.One case of early postoperative in-hospital death occurred, with a mortality rate of 2.4%, primarily due to acute left heart failure and multiple organ dysfunction. The average follow-up period for surviving children was( 64.6±34.5) months(5-147 months), with no mid- to long-term mortality. Follow-up results showed that In surviving children, the left heart showed significant reduction in size postoperatively, with the LVEDD Z-score decreasing from 1.24±2.23 before surgery to -0.97±1.48( P=0.001). Postoperative LVEF 0.66±0.06 showed no significant difference compared to pre-reintervention 0.68±0.10( P=0.140). In aortic stenosis(AS) patients, the peak transvalvular pressure gradient decreased from(69.5±19.8) mmHg(1 mmHg=0.133 kPa) preoperatively to(25.1±10.9) mmHg postoperatively( P=0.003). In aortic insufficiency(AI) patients, the width of the aortic regurgitation jet decreased from(5.8±1.1) mm preoperatively to(2.7±1.1) mm postoperatively( P=0.012). 97.5% of children maintained mild-to-moderate aortic regurgitation(jet width <4 mm), with only 1 case of moderate regurgitation(jet width 4.4 mm)remaining under close observation.Two children underwent reoperation on the aortic valve, with a tertiary intervention rate of 5.0%. One case underwent redo commissurotomy 21 months after aortic valve repair due to recurrent stenosis, and the other underwent mechanical valve replacement 34 months after the Ozaki procedure due to leaflet calcification and infective endocarditis. Mid-term follow-up revealed good cardiac function recovery in surviving children, with 87.5% achieving NYHA functional class Ⅰ/Ⅱ. Conclusion:Due to the demands of growth and development and the degenerative nature of valve tissue, residual issues are inevitable in the mid- to long-term following congenital aortic valve disease surgery in children, often necessitating secondary intervention. Given the lack of suitable autologous valve tissue, the use of aortic valve replacement has significantly increased in secondary interventions. The Ross procedure, as an ideal secondary intervention, demonstrates satisfactory mid-term follow-up outcomes. For children with high-risk factors for the Ross procedure, mechanical valve replacement also yields favorable prognoses.

Objective:To adapt and validate the Chinese version of the Supervisory Relationship Questionnaire(SRQ)and evaluate its psychometric properties among supervisees.Methods:Item analysis,exploratory factor anal-ysis(EFA)and confirmatory factor analysis(CFA)were conducted on data from 888 supervisees recruited via on-line platform.Test-retest reliability over a four-week interval was examined in a randomly selected subset of 70 su-pervisees.An additional sample of 367 supervisees completed the Supervisory Relationship Scale(SRS)to evaluate criterion validity.Results:The revised SRQ contained 65 items and 6 factors.Both exploratory factor analysis and confirmatory factor analysis supported six-factor structure(safe base,structure,commitment,reflective education,role model and formative feedback),explaining 66.52％of the variance,with factor loadings of the items ranging from 0.58 to 0.83.The revised SRQ had six factors with good fit indices(x2/df=1.31,GFI=0.81,NFI=0.87,CFI=0.97,TLI=0.90,IFI=0.91,RMSEA=0.03,SRMR=0.05).The scores of the revised SRQ were positively correlated with the scores of SRS(ICC=0.96,P＜0.01).The Cronbach α coefficient of the revised SRQ was 0.97,and the test-retest reliability coefficient(ICC)was 0.74.Conclusion:The SRQ-C demonstrates sound psy-chometric properties,including structural validity,criterion-related validity,internal consistency,and temporal stabil-ity.It is a reliable and valid instrument for assessing supervisory relationships from the supervisee perspective.

A 57-year-old male patient with lung adenocarcinoma accompanied by brain metastasis received radiotherapy and chemotherapy with poor efficacy. Subsequently, he was given camrelizumab at a dose of 200 mg intravenously once every 21 days, combined with intermittent chemotherapy or targeted drug therapy. After 22 months, the patient developed right eye pain with visual loss. Slit lamp examination showed a transverse oval shallow ulcer with clear boundary, clean surface and a maximum diameter of about 6 mm in the center of the cornea of the right eye, with positive fluorescein staining. Immune-related corneal ulcers due to camrelizumab were considered. Camrelizumab was discontinued, and the patients′ ocular symptoms were gradually improved after systemic and local glucocorticoid and corneal repair drugs were given. Seven months later, due to the patient did not follow the doctor′s advice to replace eye drops, overuse of glucocorticoid occurred, resulting in perforation of the original ulcer. The glucocorticoid-containing eye drops was discontinued, the patient underwent amniotic membrane grafting combined with amniotic membrane patching on the right eye, and the patient's condition was improved.

Objective:To investigate the current status of standardized residency training (SRT) teaching activities at Zhongshan Hospital affiliated to Fudan University, and to explore optimization strategies.Methods:We collected behavioral data from the SRT course selection platform and resident questionnaire survey data throughout 2024. Descriptive analysis, chi-square test, Mann-Whitney U test, and multivariable logistic regression analysis were performed. Results:A total of 170 teaching sessions were conducted in 2024, with interactive practice-based sessions accounting for 42.35% and lecture-based sessions accounting for 47.06%. According to 536 questionnaires, residents' overall satisfaction with teaching activities scored 87.83 points (high satisfaction, ≥85 points; moderate satisfaction, <85 points). The proportion of high satisfaction with interactive practice-based sessions was significantly higher than that with lecture-based sessions (82.81% vs. 75.46%, P=0.034). The enrollment for weekday evening courses filled up significantly faster than that for weekday daytime courses [4 (2, 6) seconds vs. 12 (8, 15) seconds, P<0.001]. Interactive practice-based sessions [odds ratio ( OR)=1.6, 95% CI=1.1-2.3, P=0.018] and weekday evening sessions ( OR=1.4, 95% CI=1.0-2.0, P=0.048) significantly improved resident satisfaction. Conclusions:Optimizing course formats and scheduling can enhance the quality of SRT teaching activities.

Intraocular ointment is conventionally placed on the eye to prevent infection after cataract surgery. The purpose of this study is to report a case and conduct a systematic review of a rare occurrence of the entry of intraocular ointment after cataract surgery. PubMed, Scopus, Embase, CNKI, WANFANG data, China Science and Technology Journal Database and Chinese Medical Journal Full-text Database were systematically searched from their commencement to 30th October 2023, and 19 literatures were screened out and 31 cases of intraocular ointment after surgery were collected. Among the 31 patients, the age of presentation ranged from 55 to 87 years with a median of 73, males accounted for 45.2% and females accounted for 32.3%. The length of the incision was generally 3.2 mm. Most of the patients detected ointment within 3 days post-operation and presented without complications(45.2%). The most common ocular manifestations were corneal edema, glaucoma and uveitis. Early postoperative follow-up is very important. Presence of anterior chamber ointment is a rare complication after cataract surgery, but it can lead to severe vision loss if not detected and treated on time. When patients complain of foreign body sensation in the in the eye after cataract surgery, ophthalmologists need to take a kin interest and examine the eye for early detection of ointment for appropriate intervention and prevent further complications.
