The view of youth moral cultivation clearly defines the scope of “morality” and puts forward the requirement of “cultivating morality” for the youth. This is a systematic concept aligned with the main theme of the times and is worth deeply exploring and integrating into the practice of medical ethics education for medical students. With the requirements for innovation and development in medical education， the cultivation of medical students has also been endowed with new connotations. Guided by the connotations of the view of youth moral cultivation and aligned with the objective requirements of medical students’ cultivation， this paper leveraged the core values of traditional Chinese medicine as its entry point. It also explored the realization paths of medical ethics education for medical students that reflect advantages， highlight characteristics， and maintain clear orientation through strengthening the medical ethics education of “dedicated study of medicine，” “honesty and prudence in words and deeds，” “benevolence in heart and skills，” and “doctor-patient trust and harmony，” aiming to cultivate guardians of people’s health with noble medical ethics and superb medical skills.

Aim To investigate the effect of recombi-nant glycoprotein hormone β5/α2(rCGH)on lipolysis in 3T3-L1 adipocytes,and explore the underlying mechanism.Methods 3T3-L1 preadipocytes were cultured and induced to differentiate into mature adipo-cytes,then treated with different concentrations of rCGH for 24 h in vitro.Cell viability of 3T3-L1 adipo-cytes was evaluated by CCK-8 assay,the levels of in-tracellular triglyceride(TG)and glycerol in the culture supernatant were measured by enzymatic method,and the changes of lipid droplets were observed by oil red O staining.The expression levels of HSL and ATGL lipo-lytic proteins in adipocytes were detected by Western blot.To carry out the intervention experiment with dif-ferent concentrations of rCGH with or without the PKA inhibitor,H89,on the mature 3T3-L1 adipocytes,the cultured cells were divided into the control group,H89 pre treatment group,1 μmol·L-1 rCGH group,and(1 μmol·L-1 rCGH+H89)combined intervention group.The contents of intracellular TG and free glycer-ol were measured by enzymatic method,and the ex-pression of CREB and lipolysis-related proteins was de-tected using Western blot.Results Different concen-trations of rCGH(0.25,0.5,1,and 2 μmol·L-1)had no significant effect on the cell viability of adipo-cytes(P＞0.05).Compared with the control group,the treatment with rCGH significantly decreased the size of lipid droplets and intracellular TG content,while significantly elevated glycerol concentration in cell supernatant.rCGH treatment also stimulated the protein expression of p-HSL,ATGL,and p-PKA.In addition,the addition of a PKA inhibitor,H89,atten-uated the effects of rCGH on free glycerol level,intra-cellular TG content,and the expression of p-HSL,p-PLIN1,and p-CREB.Conclusions rCGH enhances the lipolysis of 3T3-L1 adipocytes by up-regulating the activities of HSL,ATGL and PKA,promoting glycerol release,inhibiting TG synthesis and lipid accumula-tion,and its mechanism of action is related to the acti-vation of cAMP/PKA/CREB signaling pathway.

Objective With the widespread of transcatheter aortic valve replacement(TAVR)in patients with severe symptomatic aortic stenosis(AS),the life-cycle management has become a major determinant of prognosis.Methods A total of 408 AS patients who underwent successfully TAVR from June 2021 to August 2023 were consecutively enrolled in Hospital Valve Intervention Center.Patients were assigned to the Usual Care(UC)group between June 2021 and October 2022,while patients were assigned to the Heart Multi-parameter Monitoring(HMM)group between November 2022 and August 2023.The primary endpoint was defined as composite endpoint within 6 months post-TAVR,including all-cause death,cardiovascular death,stroke/transient ischemic attack,conduction block,myocardial infarction,heart failure rehospitalization,and major bleeding events.Secondary endpoints were the time interval(in hours)from event occurrence to medical consultation or advice and patient satisfaction.Statistical analysis was performed using Kaplan-Meier and multivariable Cox proportional hazards models.Results The incidence of primary endpoint in HMM group was significantly lower than that in UC group(8.9％vs.17.7％,P=0.016),the driving event was the rate of diagnosis and recognition of conduction block.The average time intervals from event occurrence to receiving medical advice were 3.02 h in HHM group vs.97.09 h in UC group(P＜0.001).Using cardiac monitoring devices and smart healthcare platforms provided significant improving in patients long-term management(HR 0.439,95％CI 0.244-0.790,P=0.006).Conclusions The utilization of cardiac monitoring devices and smart healthcare platforms effectively alerted clinical events and improved postoperative quality of life during long-term management post TAVR.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To investigate the prognostic significance of DTA(DNMT3A,TET2,ASXL1)gene mutations in patients with non-M3 acute myeloid leukemia(AML).Methods:The clinical data of 180 newly diagnosed AML patients hospitalized in the First People's Hospital of Changzhou from January 2018 to April 2022 were retrospectively analyzed.Next-generation sequencing technology was used to detect 150 gene mutations in the patients,and log-rank tests and Cox regression models were used to analyze the prognostic factors.Results:DTA gene mutations were detected in 83(46.1％)of 180 AML patients.Compared to patients without DTA mutations,patients with DTA mutations were significantly older(P＜0.001).The median overall survival(OS)time and disease-free survival(DFS)time in the DTA mutation group were significantly shorter than those in the group without DTA mutation(both P＜0.05).Multivariate analysis showed that age ≥ 60 years(P＜0.001),with DTA mutation(P=0.018),and intermediate-risk(relative to favorable-risk)(P=0.005)were independent risk factors for OS in AML patients.Conclusion:AML patients with DTA mutations are relatively older,with shorter median OS time and DFS time,and poor prognosis.

Objective: This study aimed to evaluate the effects of 2 endoscopic spine surgeries on the biomechanical properties of normal and osteoporotic spines. Methods: Based on computed tomography images of a healthy adult volunteer, 6 finite element models were created. After validating the normal intact model, a concentrated force of 400 N and a moment of 7.5 Nm were exerted on the upper surface of L3 to simulate 6 physiological activities of the spine. Five types of indices were used to assess the biomechanical properties of the 6 models, range of motion (ROM), maximum displacement value, intervertebral disc stress, maximum stress value, and articular protrusion stress, and by combining them with finite element stress cloud. Results: In normal and osteoporotic spines, there was no meaningful change in ROM or disc stress in the 2 surgical models for the 6 motion states. Model N1 (osteoporotic percutaneous transforaminal endoscopic discectomy model) showed a decrease in maximum displacement value of 20.28% in right lateral bending. Model M2 (unilateral biportal endoscopic model) increased maximum displacement values of 16.88% and 17.82% during left and right lateral bending, respectively. The maximum stress value of L4–5 increased by 11.72% for model M2 during left rotation. In addition, using the same surgical approach, ROM, maximum displacement values, disc stress, and maximum stress values were more significant in the osteoporotic model than in the normal model. Conclusion In both normal and osteoporotic spines, both surgical approaches were less disruptive to the physiologic structure of the spine. Furthermore, using the same endoscopic spine surgery, normal spine biomechanical properties are superior to osteoporotic spines.

Objective The purpose of writing the"Expert consensus on the prevention and control of intracranial hypertension in adult critical illness"(here in after referred to as the"Consensus")aimed to standardize the nursing work related to the prevention and control of elevated intracranial pressure in adult critical illness,and prevent the occurrence of complications such as cerebral herniation.Methods Guided by evidence-based practice,domestic and foreign databases were searched for guidelines,expert consensuses,systematic evaluation,evidence summaries,and original research related to increased intracranial pressure.The search period is from database establishment to March 2024.The high-quality evidence and suggestions in the field was evaluated,extracted,and summarized to form a preliminary consensus.27 experts were invited to conduct 2 rounds of expert inquiry and 8 experts were invited to conduct 2 expert discussion meetings,to revise and improve the content of the initial draft,and to ultimately form a final consensus.Results The effective response rates for both rounds of inquiry questionnaires were 100％,with expert authority coefficients of 0.884,judgment coefficients of 0.964,and familiarity levels of 0.804.The Kendall harmony coefficients for 2 rounds of inquiry were 0.107 and 0.083(P＜0.01),respectively.The consensus includes 4 aspects,including identification,monitoring,prevention and control strategies,emergency treatment and care for increased intracranial pressure.Conclusion This"Consensus"has strong scientific validity and can provide reference basis for nurses to carry out prevention and control of intracranial pressure increase.

Objective:To investigate the clinical and gene variant characteristics of PCDH19 gene related epilepsy, and improve the ability of clinicians in early disease identification. Methods:The clinical data of 3 PCDH19 gene related epilepsy patients admitted to Children′s Hospital Affiliated to Zhengzhou University from October 2018 to August 2023 diagnosed by gene detection were reviewed and analyzed. Results:All the patients are female, and the onset age of seizure ranged in their infancy. Seizures in clusters and fever sensitivity were observed in all patients, and were very hard to control by single-drug treatment. Proband 1 was seizure-free after 2 kinds of anti-epileptic drug treatment, but with mild degree of intellectual disability. Proband 2 had refractory epilepsy with severe degree of intellectual disability. Proband 3 was seizure-free after 2 kinds of anti-epileptic drug treatment and without intellectual disability. In the first family, the proband carried heterozygous c.369C>G variant in the PCDH19 gene which was identified as de novo after parental validation. In the second family, the proband carried c.1652T>A variant inherited from her mother. In the third family, the proband carried c.278G>A variant inherited from her father. The 3 mutations had not been reported in the Human Gene Mutation Database. Conclusions:PCDH19 gene related epilepsy is one special kind of X-linked inherited epilepsy syndrome characterized by seizures in clusters and sensitivity to fever. And gene detection can help with early diagnosis and make rational clinical strategies in time. The variants c.369C>G, c.1652T>A and c.278G>A have enriched the gene variant spectrum of PCDH19.
