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 evaluate the technical feasibility and perioperative safety of pyeloplasty assis-ted by the CarinaTM modular laparoscopic surgical robotic system in patients with ureteropelvic junction obstruction(UPJO).Methods:From November to December 2024,five consecutive patients diagnosed with UPJO underwent robot-assisted pyeloplasty using the CarinaTM modular laparoscopic surgical system at Peking University First Hospital.Data on patient demographics,intraoperative parameters(including docking time,console time,and estimated blood loss),perioperative outcomes,follow-up results,and surgeons' subjective evaluations of system performance were prospectively collected.Descriptive statistics were used;continuous variables were presented as median(range),and categorical variables as frequen-cy and percentage.Results:The cohort included four females and one male.All the patients successfully completed the robotic procedure without conversion to open or conventional laparoscopic surgery.The me-dian age was 32 years(24-37 years),and the median body mass index was 21.6 kg/m2(15.8-27.3 kg/m2).The median docking time was 8 min(3-12 min),and the median console time was 91 min(71-125 min).Intraoperative blood loss was uniformly 20 mL.The median postoperative drainage du-ration was 3 d(0-4 d),and the median length of hospital stay was 4 d(4-9 d).No Clavien-Dindo grade Ⅲ or higher complications occurred.All the patients had their double-J stents removed at 2 months postoperatively,and pain in the ipsilateral flank,reported preoperatively by all the five patients,was al-leviated.The subjective surgical success rate was 100％.Surgeons reported stable system performance throughout all the procedures,with no instances of mechanical arm interference or visual drift affecting surgical fluency.Conclusion:Preliminary findings indicate that pyeloplasty using the domestically deve-loped CarinaTM modular laparoscopic robotic system is technically feasible and perioperatively safe for the treatment of UPJO.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective To understand the changing composition and antibiotic resistance of bacterial species in the clinical isolates from outpatient and emergency department(hereinafter referred to as outpatients)and inpatient children over time in various hospitals,and to provide laboratory evidence for rational antibiotic use.Methods The data on clinically isolated pathogenic bacteria and antimicrobial susceptibility of isolates from outpatients and inpatient children in the CHINET program from 2015 to 2021 were collected and analyzed.Results A total of 278 471 isolates were isolated from pediatric patients in the CHINET program from 2015 to 2021.About 17.1％of the strains were isolated from outpatients,primarily group A β-hemolytic Streptococcus,Escherichia coli,and Staphylococcus aureus.Most of the strains(82.9％)were isolated from inpatients,mainly SS.aureus,E.coli,and H.influenzae.The prevalence of methicillin-resistant S.aureus(MRSA)in outpatients(24.5％)was lower than that in inpatient children(31.5％).The MRSA isolates from outpatients showed lower resistance rates to the antibiotics tested than the strains isolated from inpatient children.The prevalence of vancomycin-resistant Enterococcus faecalis or E.faecium and penicillin-resistant S.pneumoniae was low in either outpatients or inpatient children.S.pneumoniae,β-hemolytic Streptococcus and S.viridans showed high resistance rates to erythromycin.The prevalence of erythromycin-resistant group A β-hemolytic Streptococcus was higher in outpatients than that in inpatient children.The prevalence of β-lactamase-producing H.influenzae showed an overall upward trend in children,but lower in outpatients(45.1％)than in inpatient children(59.4％).The prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKpn),carbapenem-resistant Pseudomonas aeruginosa(CRPae)and carbapenem-resistant Acinetobacter baumannii(CRAba)was 14％,11.7％,47.8％in outpatients,but 24.2％,20.6％,and 52.8％in inpatient children,respectively.The prevalence of multidrug-resistant E.coli,K.pneumoniae,Proteus mirabilis,P.aeruginosa and A.baumannii strains was lower in outpatients than in inpatient children.The prevalence of fluoroquinolone-resistant E.coli,ESBLs-producing K.pneumoniae,ESBLs-producing P.mirabilis,carbapenem-resistant E.coli(CREco),CRKpn,and CRPae was lower in children in outpatients than in inpatient children,but the prevalence of CRAba in 2021 was higher than in inpatient children.Conclusions The distribution of clinical isolates from children is different between outpatients and inpatients.The prevalence of MRSA,ESBL,and CRO was higher in inpatient children than in outpatients.Antibiotics should be used rationally in clinical practice based on etiological diagnosis and antimicrobial susceptibility test results.Ongoing antimicrobial resistance surveillance and prevention and control of hospital infections are crucial to curbing bacterial resistance.

Objective To investigate the changing antibiotic resistance profiles of E.coli isolated from patients in the 52 hospitals participating in the CHINET program from 2015 to 2021.Methods Antimicrobial susceptibility was tested for clinical isolates of E.coli according to the unified protocol of CHINET program.WHONET 5.6 and SPSS 20.0 software were used for data analysis.Results Atotal of 289 760 nonduplicate clinical strains ofE.coli were isolated from 2015 to 2021,mainly from urine samples(44.7±3.2)％.The proportion of E.coli strains isolated from urine samples was higher in females than in males(59.0％vs 29.5％).The proportion of E.coli strains isolated from respiratory tract and cerebrospinal fluid samples was significantly higher in children than in adults(16.7％vs 7.8％,0.8％vs 0.1％,both P＜0.05).The isolates from internal medicine department accounted for the largest proportion(28.9±2.8)％with an increasing trend over years.Overall,the prevalence of ESBLs-producing E.coli and carbapenem resistant E.coli(CREco)was 55.9％and 1.8％,respectively during the 7-year period.The prevalence of ESBLs-producing E.coli was the highest in tertiary hospitals each year from 2015 to 2021 compared to secondary hospitals.The prevalence of CREco was higher in children's hospitals compared to secondary and tertiary hospitals each year from 2015 to 2021.The prevalence of ESBLs-producing E.coli in tertiary hospitals and children's hospitals and the prevalence of CREco in children's hospitals showed a decreasing trend over the 7-year period.The prevalence of CREco in secondary and tertiary hospitals increased slowly.Antibiotic resistance rates changed slowly from 2015 to 2021.Carbapenem drugs(imipenem,meropenem)were the most active drugs amongβ-lactams against E.coli(resistance rate≤2.1％).The resistance rates of E.coli to β-lactam/β-lactam inhibitor combinations(piperacillin-tazobactam,cefoperazone-sulbactam),aminoglycosides(amikacin),nitrofurantoin and fosfomycin(for urinary isolates only)were all less than 10％.The resistance rate of E.coli strains to antibiotics varied with the level of hospitals and the departments where the strains were isolated,especially for cefazolin and ciprofloxacin,to which the resistance rate of E.coli strains from children in non-ICU departments was significantly lower than that of the strains isolated from other departments(P＜0.05).The E.coli isolates from ICU showed higher resistance rate to most antimicrobial agents tested(excluding tigecycline)than the strains isolated from other departments.The E.coli strains isolated from tertiary hospitals showed higher resistance rates to the antimicrobial agents tested(excluding tigecycline,polymyxin B,cefepime and carbapenems)than the strains from secondary hospitals and children's hospitals.Conclusions E.coli is an important pathogen causing clinical infection.More than half of the clinical isolates produced ESBL.The prevalence of CREco is increasing in secondary and tertiary hospitals over the 7-year period even though the overall prevalence is still low.This is an issue of concern.

Natural products (NPs) have historically been a fundamental source for drug discovery. Yet the complex nature of NPs presents substantial challenges in pinpointing bioactive constituents, and corresponding targets. In the present study, an innovative natural product virtual screening-interaction-phenotype (NP-VIP) strategy that integrates virtual screening, chemical proteomics, and metabolomics to identify and validate the bioactive targets of NPs. This approach reduces false positive results and enhances the efficiency of target identification. Salvia miltiorrhiza (SM), a herb with recognized therapeutic potential against ischemic stroke (IS), was used to illustrate the workflow. Utilizing virtual screening, chemical proteomics, and metabolomics, potential therapeutic targets for SM in the IS treatment were identified, totaling 29, 100, and 78, respectively. Further analysis via the NP-VIP strategy highlighted five high-confidence targets, including poly [ADP-ribose] polymerase 1 (PARP1), signal transducer and activator of transcription 3 (STAT3), amyloid precursor protein (APP), glutamate-ammonia ligase (GLUL), and glutamate decarboxylase 67 (GAD67). These targets were subsequently validated and found to play critical roles in the neuroprotective effects of SM. The study not only underscores the importance of SM in treating IS but also sets a precedent for NP research, proposing a comprehensive approach that could be adapted for broader pharmacological explorations.

Objective To explore the association between knee torsion and multiple bony abnormali-ties of the lower limb in patients with recurrent patellar dislocation(RPD).Methods The preoperative imaging data of RPD patients treated in our institution between May 2020 and October 2024 were col-lected retrospectively.A total of 238 patients were included in this study,with 83.6%being females.All patients underwent standard hip-knee-ankle CT scans,and lower limb bony structural parameters were reconstructed and measured using Mimics 20.0,focusing on variables such as knee torsion,femo-ral anteversion(FAA),femoral distal torsion angle(DFTA),supratrochlear spur,tibial tuberosity to trochlear groove distance(TT-TG),Caton-Deschamps index,and tibial torsion.Bony abnormalities were categorized based on previously established risk thresholds.Moreover,chi-square tests were em-ployed to compare the composition ratio differences between knee torsion and multiple lower limb osse-ous abnormalities.Results Among all affected knees,the proportion of excessive knee torsion was 33.6%,while in cases with osseous abnormalities,the value was over 40%.Compared with cases of low knee torsion,patients with excessive knee torsion showed significantly higher proportions of FAA(41.3%vs.27.2%,P=0.028),excessive DFTA(60%vs.32.9%,P<0.001),supratrochlear spur(55%vs.38.6%,P=0.016),trochlear dysplasia(93.8%vs.73.4%,P<0.001),excessive TT-TG(68.8%vs.43.7%,P<0.001),and patella alta(50%vs.22.2%,P<0.001).Additionally,95%of knees with excessive torsion exhibited two or more bony risk factors,whereas 55%had four or more bony structural abnormalities,which was significantly higher than those of low knee torsion(55%vs.21.5%,P<0.001).Conclusion In RPD patients,excessive knee torsion is associated with multiple low-er limb bony abnormalities.Moreover,patients with high knee torsion(>12°)are significantly more likely to have multiple bony abnormalities than those with low torsion.Therefore,in surgical decision-making for such patients,lower limb bony abnormalities should be assessed comprehensively.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective:To analyze the intercomparision result of personal dose monitoring and gross alpha/beta detection capability between the disease control and prevention institutions at provincial, municpal and county levels during 2022-2024, in order to provide a reference for radiation detection capability and policy making of these institutions in China.Methods:Data on personal dose monitoring and gross alpha/beta detection, obtanied from the 2022-2024 radiation detection capability intercomparison between the disease control and prevention institutions at different levels, were recorded. Both the qualification rates (including excellence) and excellence rates of all the institutions at all evels from 2022 to 2024 were analyzed using SPSS 22.0.Results:From 2022 to 2024, the number of participating institutions at all levels showed an overall upward trend, increasing from 262 to 430, with particularly notable growth at the municipal level. In the 2024 gross α/β detection capability intercomparison, the non-qualification rate in municipal-level institutions was significantly higher than in county-level institutions ( χ2=10.53, P < 0.05). The qualification rate (including excellence) of the municipal-level gross alpha/beta detection in 2022 and 2024 were lower than in 2023( χ2=29.93, P < 0.01). Among all regions, the 2024 personal dose monitoring intercomparison result showed that the qualification rate (including excellence) in East China was higher than in Southwest and Northwest China ( χ2=15.62, P <0.01). East China also outperformed Northwest China ( χ2=16.21, P <0.01). In the 2022 gross alpha/beta detection capability intercomparison, the qualification rate (including excellent performance) in East China and South China was higher than in Northwest China ( χ2=23.76, 11.22, P<0.01). Overall, East China showed relatively higher qualification rate in intercomparison result of both personal dose monitoring and radiation detection (including excellence), while Northwest China showed lower qualification rates (including excellence). Conclusions:Although the radiation detection capability of disease control and prevention institutions at all levels has improved in recent years, there are still insufficience of detection capabilities at some municipal- and county-level laboratories and even unbalance between different regionas. Policy support should prioritize underdeveloped areas, such as municipal- and county-level institutions and the Northwest, and enhance the technical proficiency and quality management of laboratory personnel.
