On October 9， 2024， the General Office of the National Health Commission， the General Office of the Ministry of Education， the General Department of the National Administration of Traditional Chinese Medicine， and the General Department of the National Bureau of Disease Control and Prevention jointly issued the Action Plan for Enhancing Medical Humanistic Care （2024-2027）， stating that medical humanistic spirit is a concrete manifestation of humanistic spirit in the medical field. Aiming at caring for and respecting patients， this spirit reflects the attitude of medicine towards life. The cultivation of medical humanistic care competencies should serve as a core element of modern medical education， running through the entire process of the medical students’ training system and the full stage of medical workers’ career development. The humanities team of Harbin Medical University pioneered the “consistent system” concept of medical humanities education， inherited the “four-stage” with clinical practice as the primary approach， and closely focused on “three combinations， two considerations， and one assessment.” Through deeply integrating medicine with the humanities， as well as theory with practice， they have embarked on a distinctive implementation path of medical humanities， laying a solid foundation for the cultivation of high-quality medical talents with both skills and expertise in practice.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Objective:To explore the association between macrosomia delivery history and adverse pregnancy outcomes in subsequent pregnancies under different stratification of gestational weight gain(GWG).Methods:A retrospective study was conducted on 500 multiparous women with a history of macrosomia delivery who gave birth at The Second Hospital of Jilin University from January 2020 to November 2023.Meanwhile,1500 multiparous women without a history of delivering macrosomic infants were selected as the control group through 1∶3 matc-hing based on age(±1 year).The differences in general characteristics,GWG,and pregnancy outcomes be-tween the two groups were compared.According to the appropriate GWG values recommended by Chinese health industry standards,pregnant women in both groups were classified into insufficient GWG,appropriate GWG,and excessive GWG.Multivariate Logistic regression analysis was used to compare the relationship be-tween a history of macrosomia delivery and adverse pregnancy outcomes under different GWG stratifications.Re-sults:The History of macrosomia group had significantly higher rates of excessive GWG(50.60%vs.48.13%),incidence of gestational diabetes mellitus(GDM)(23.40%vs.17.07%),rate of cesarean section(60.20%vs.45.33%),and rate of macrosomia(26.60%vs.7.87%)compared to the control group(P<0.05).Multivariate Logistic regression analysis showed that a history of macrosomia delivery was an independent risk factor for GDM,cesarean section,and macrosomia in subsequent pregnancies(aOR>1,P<0.05).Stratified analysis based on GWG revealed that,compared with the control group,regardless of the GWG status,the risk of cesare-an section and macrosomia was higher in women with a history of macrosomia delivery(aOR>1,P<0.05).Mo-reover,for those with a history of macrosomia delivery and excessive weight gain during pregnancy,the risk of preeclampsia(aOR 3.167,P<0.05)and GDM(aOR 1.661,P<0.05)was significantly increased.When the GWG was appropriate for pregnant women with a history of macrosomia delivery,there was no significant correla-tion between a history of macrosomia delivery and preeclampsia or GDM(P>0.05).Conclusions:A history of macrosomia delivery increased the risk of multiple adverse pregnancy outcomes,such as GDM,cesarean section,and macrosomia.For multiparous women at different GWG levels,the risk of cesarean section and macrosomia was significantly increased in those with a history of macrosomia delivery.When GWG was appropriate,a history of macrosomia delivery was not found to be an independent risk factor for preeclampsia and GDM.

Objective:To study the clinical outcome of palmar approach to on-top plasty in the treatment of unequal radial polydactyly.Methods:A retrospective analysis was conducted on patients with unequal radial polydactyly in which neither thumb duplicates possess both well-developed proximal and distal components. All the patients underwent palmar approach to on-top plasty between September 2013 and September 2023 at Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine and Shanxi Children’s Hospital. At the final follow-up, the active flexion-extension range of motion of the first metacarpophalangeal and interphalangeal joints was measured, along with grip and pinch strength. The Vancouver scar scale was used to assess scar formation (total score 0-15, with higher scores indicating more severe scarring). Additionally, the pediatric quality of life inventory (total score 0-100, with higher scores indicating better quality of life, evaluated by the children themselves or by their parents/guardians on their behalf) and the satisfaction questionnaire (total score ranges from 1 to 5, with higher scores indicating greater satisfaction) were used to assess the patients’ daily quality of life and parents’satisfaction.Results:A total of 28 pediatric patients were included, comprising 15 males and 13 females, with an average age of 15 months (range: 10-36 months). All cases presented unilateral radial polydactyly, including 18 right hands and 10 left hands. The mean follow-up duration was 4.2 years (range: 1.5-6.0 years). All incisions healed in one stage, and the skin flaps survived well without infection. Joint stability was maintained without any deviation. All reconstructed thumbs demonstrated satisfactory aesthetic appearance. The reconstructed thumbs demonstrated mean active flexion-extension arcs of 76° (range 61°-85°) at the first metacarpophalangeal joint, and 42° (range 21°-65°) at the interphalangeal joint. The grip strength of the hand was 82% (63%-90%) of the normal opposite hand. The key, tip and tripod pinch strength were 76%(66%-83%), 77%(66%-85%) and 79%(68%-87%) of the normal opposite hand, respectively. No scar hyperplasia was found in all cases, and the Vancouver scar scale score was 1.2(0-3) points. The self-assessment score of the children on the pediatric quality of life inventory was 86 points, and the score of the parents/guardians was 91 points. In terms of family satisfaction, 23 patients scored 5, and 5 patients scored 4.Conclusion:The use of palmar approach to on-top plasty to treat unequal radial polydactyly can achieve functional and aesthetic results.

BACKGROUND:At present,a large number of studies have shown that mesenchymal stem cells can be combined with different strategies to more effectively improve liver fibrosis and inhibit its progression to end-stage liver disease.OBJECTIVE:To explore the mechanism of mesenchymal stem cells combined with different strategies to improve liver fibrosis compared with mesenchymal stem cells alone.METHODS:The first author used computers to search CNKI,WanFang,VIP,PubMed,Web of Science,and Nature databases involving mesenchymal stem cells combined with different strategies to improve liver fibrosis.The search terms were"mesenchymal stem cells,liver fibrosis,combination therapy,liver stellate cells"in Chinese,and"mesenchymal stem/stromal cells,liver/hepatic fibrosis/cirrhosis,combination therapy,hepatic stellate cells/HSCs"in English.By quickly browsing the title and abstract of the article,excluding the articles that are not closely related to the topic,104 articles were finally selected for review analysis.RESULTS AND CONCLUSION:Mesenchymal stem cells improve liver fibrosis by differentiating into hepato-like cells,inhibiting hepatic stellate cell activation,immune regulation,and other mechanisms.However,the low rate of liver colonization,low survival rate,and short action time of mesenchymal stem cells after transplantation limit their clinical application.Mesenchymal stem cells can improve liver fibrosis through a combination of drugs,gene modification,cytokines and other strategies,and the efficacy is better than that of mesenchymal stem cells alone.Moreover,the combination of mesenchymal stem cells and different strategies can effectively improve liver fibrosis by promoting mesenchymal stem cell homing,inhibiting hepatic stellate cell activation,regulating the microenvironment,and regulating signaling pathways.Mesenchymal stem cells can also show better liver-derived differentiation,homing and survival functions in reducing liver fibrosis through pretreatment,miRNA regulation and combination with other cells.The combination of mesenchymal stem cells and different strategies cannot avoid the potential risks of mesenchymal stem cells alone in the treatment of liver fibrosis,and the safety of these strategies(drugs,gene modifications,cytokines,etc.)is also worth considering.In addition,the number and route of mesenchymal stem cell transplantation need to be further studied.

OBJECTIVE To investigate the effect and underlying mechanism of hydroxytyrosol(HT)on mouse chondrocyte injury induced by oxidative stress.METHODS Mouse chondrocytes were incubated with varying concentrations of HT 0-400 μmol L-1 for 24 h,and the viability of the mouse chondrocytes was assessed using CCK-8 kit.An oxidative stress model of chondrocytes was estab-lished by the addition of H2O2 200 μmol L-1.The experimental groups included the cell control group,H2O2 group,and H2O2+HT 10,50 and 250 μmol·L-1 groups.After 24 h,the mRNA expression levels of interleukin-6(IL-6),cyclooxygenase-2(COX-2),prostaglandin E2(PGE2),inducible nitric oxide synthase(iNOS),matrix metalloproteinase-3(MMP-3),MMP-13,a disintegrin and metalloproteinase with throm-bospondin motifs-4(ADAMTS-4),ADAMTS-5,SRY-box transcription factor-9(SOX-9)and aggrecan(ACAN)in mouse chondrocytes were detected by real-time quantitative PCR,the intracellular reactive oxygen species(ROS)level in chondrocytes was measured with 2,7-dichlorodihydrofluorescein diace-tate(DCFH-DA)staining,while the mitochondrial membrane potential was evaluated using JC-1 staining.After 48 h,the protein expression levels of iNOS,COX-2,MMP-13,and type Ⅱ collagen(Col-2)in mouse chondrocytes were detected using Western blotting.RESULTS HT at concentrations≤350 μmol·L-1 had no significant effect on the survival of mouse chondrocytes.Compared with the cell control group,after 24 h,the mRNA expression levels of IL-6,COX-2,PGE2,iNOS,MMP-3,MMP-13,ADAMTS-4 and ADAMTS-5 in the chondrocytes of mice in the H2O2 group were increased,while the mRNA expression levels of SOX-9 and ACAN were decreased.Additionally,there was an elevation in the ROS level and a significant loss of mitochondrial membrane potential in the chondrocytes of mice.Compared with the H2O2 group,after treatment with HT 10,50 and 250 μmol·L-1,there were significant decreases in mRNA expression levels of IL-6,COX-2,PGE2,iNOS,MM P-3,MMP-13,ADAMTS-4 and ADAMTS-5,the mRNA expressions of SOX-9 and ACAN were increased,the ROS level was lowered.After treatment with HT 50 and 250 μmol L-1,the loss of mitochondrial membrane potential was ameliorated.Compared to the cell control group,the protein expressions of iNOS,COX-2 and MMP-13 were upregulated in the H2O2 group,while the protein expression of Col-2 was downregulated after 48 h.Compared to the H2O2 group,treatment with HT at concentrations of 10,50 and 250 μmol·L-1 resulted in decreased protein expressions of iNOS,COX-2 and MMP-13 in mouse chondrocytes,but the protein expression of Col-2 increased following treatment with HT 50 and 250 μmol L-1.CONCLUSION HT can ameliorate H2O2-induced chondrocyte injury by reducing intracellular ROS levels and alleviating the loss of mitochondrial membrane potential,suppressing the release of inflammatory cytokines,inhibiting catabolic processes,and promoting anabolic activities.

BACKGROUND:In recent years,brain-computer interface technology has shown significant promise for rehabilitating limb dysfunction in stroke patients.With ongoing research deepening and its broader clinical application,combining brain-computer interface with other rehabilitation therapies to improve limb function has become a focal point of study.OBJECTIVE:To analyze and summarize the efficacy of brain-computer interface combined with various therapies in treating limb dysfunction in stroke patients and to explore the clinical value of these combined strategies.METHODS:The search terms used for the literature review in Chinese databases were"brain-computer interface,BCI,stroke,"while the terms"brain-computer interface,BCI,brain-computer interaction,brain-machine interface,BMI,stroke"were used for English databases.Literature searches were conducted in CNKI,WanFang,VIP,PubMed,Embase,and Web of Science,from the time of database construction to September 2024.Finally,a total of 3 054 articles were retrieved,and 75 articles were included after screening for summarization.RESULTS AND CONCLUSION:Currently,brain-computer interfaces,used alone or in combination with other treatments such as Chinese medical treatment,conventional rehabilitation therapy,or physical factor therapy,are achieving better outcomes in treating limb dysfunction in stroke patients.However,the efficacy of brain-computer interfaces combined with transcranial direct current stimulation for treating upper and lower limb dysfunctions is still debated.Researchers are increasingly recognizing the feasibility of these combined therapies.Yet,challenges such as limited exploration of therapeutic mechanisms,absence of standardized protocols,and small sample sizes hinder their broad application.Future research should therefore focus on understanding the mechanisms by which brain-computer interfaces can enhance effects when combined with other therapies and on standardizing criteria for clinical trials to enable widespread clinical adoption.

Objective To investigate the distribution and antimicrobial resistance profiles of common pathogens isolated from cerebrospinal fluid(CSF)in CHINET program from 2015 to 2021.Methods The bacterial strains isolated from CSF were identified in accordance with clinical microbiology practice standards.Antimicrobial susceptibility test was conducted using Kirby-Bauer method and automated systems per the unified CHINET protocol.Results A total of 14 014 bacterial strains were isolated from CSF samples from 2015 to 2021,including the strains isolated from inpatients(95.3％)and from outpatient and emergency care patients(4.7％).Overall,19.6％of the isolates were from children and 80.4％were from adults.Gram-positive and Gram-negative bacteria accounted for 68.0％and 32.0％,respectively.Coagulase negative Staphylococcus accounted for 73.0％of the total Gram-positive bacterial isolates.The prevalence of MRSA was 38.2％in children and 45.6％in adults.The prevalence of MRCNS was 67.6％in adults and 69.5％in children.A small number of vancomycin-resistant Enterococcus faecium(2.2％)and linezolid-resistant Enterococcus faecalis(3.1％)were isolated from adult patients.The resistance rates of Escherichia coli and Klebsiella pneumoniae to ceftriaxone were 52.2％and 76.4％in children,70.5％and 63.5％in adults.The prevalence of carbapenem-resistant E.coli and K.pneumoniae(CRKP)was 1.3％and 47.7％in children,6.4％and 47.9％in adults.The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)and Pseudomonas aeruginosa(CRPA)was 74.0％and 37.1％in children,81.7％and 39.9％in adults.Conclusions The data derived from antimicrobial resistance surveillance are crucial for clinicians to make evidence-based decisions regarding antibiotic therapy.Attention should be paid to the Gram-negative bacteria,especially CRKP and CRAB in central nervous system(CNS)infections.Ongoing antimicrobial resistance surveillance is helpful for optimizing antibiotic use in CNS infections.

Objective To investigate the antimicrobial resistance of clinical isolates from elderly patients(≥65 years)in major medical institutions across China.Methods Bacterial strains were isolated from elderly patients in 52 hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program during the period from 2015 to 2021.Antimicrobial susceptibility test was carried out by disk diffusion method and automated systems according to the same CHINET protocol.The data were interpreted in accordance with the breakpoints recommended by the Clinical and Laboratory Standards Institute(CLSI)in 2021.Results A total of 514 715 nonduplicate clinical isolates were collected from elderly patients in 52 hospitals from January 1,2015 to December 31,2021.The number of isolates accounted for 34.3％of the total number of clinical isolates from all patients.Overall,21.8％of the 514 715 strains were gram-positive bacteria,and 78.2％were gram-negative bacteria.Majority(90.9％)of the strains were isolated from inpatients.About 42.9％of the strains were isolated from respiratory specimens,and 22.9％were isolated from urine.More than half(60.7％)of the strains were isolated from male patients,and 39.3％isolated from females.About 51.1％of the strains were isolated from patients aged 65-＜75 years.The prevalence of methicillin-resistant strains(MRSA)was 38.8％in 32 190 strains of Staphylococcus aureus.No vancomycin-or linezolid-resistant strains were found.The resistance rate of E.faecalis to most antibiotics was significantly lower than that of Enterococcus faecium,but a few vancomycin-resistant strains(0.2％,1.5％)and linezolid-resistant strains(3.4％,0.3％)were found in E.faecalis and E.faecium.The prevalence of penicillin-susceptible S.pneumoniae(PSSP),penicillin-intermediate S.pneumoniae(PISP),and penicillin-resistant S.pneumoniae(PRSP)was 94.3％,4.0％,and 1.7％in nonmeningitis S.pneumoniae isolates.The resistance rates of Klebsiella spp.(Klebsiella pneumoniae 93.2％)to imipenem and meropenem were 20.9％and 22.3％,respectively.Other Enterobacterales species were highly sensitive to carbapenem antibiotics.Only 1.7％-7.8％of other Enterobacterales strains were resistant to carbapenems.The resistance rates of Acinetobacter spp.(Acinetobacter baumannii 90.6％)to imipenem and meropenem were 68.4％and 70.6％respectively,while 28.5％and 24.3％of P.aeruginosa strains were resistant to imipenem and meropenem,respectively.Conclusions The number of clinical isolates from elderly patients is increasing year by year,especially in the 65-＜75 age group.Respiratory tract isolates were more prevalent in male elderly patients,and urinary tract isolates were more prevalent in female elderly patients.Klebsiella isolates were increasingly resistant to multiple antimicrobial agents,especially carbapenems.Antimicrobial resistance surveillance is helpful for accurate empirical antimicrobial therapy in elderly patients.
