Objective:To explore the interest of medical students in innovation and entrepreneurship education,providing a reference for optimizing the innovation and entrepreneurship education system.Methods:A total of 510 students from the first to fifth academic years at a medical school were selected as the study subjects.An anonymous online survey was conducted via Questionnaire Star to assess students'understanding of innovation and entrepreneurship cognition,willingness,and the current status of education,and interest scores across different majors were compared.Results:The survey revealed that 92.35%of medical students expressed interest in innovation and entrepreneurship and 96.08%of medical students recognized its importance for personal career development.About 83.53%of medical students believed it was essential for medical schools to cultivate innovation and entrepreneurship awareness,yet only 50.98%viewed it as a means to develop innovative projects.Regarding the current educational environment,over 95%of students affirmed the school's initiatives,supportive atmosphere,and resource provision.However,only 32.35%had participated in extracurricular innovation and entrepreneurship activities.During the process of innovation and entrepreneurship,87.65%of the students believed that lack of experience was the main obstacle.And 80.59%of the students hope that the school could provide venues and financial support.And 90.19%of the students expected that school-enterprise cooperation could increase practical opportunities.Additionally,professional background significantly influenced students'interest,with dental medicine students scoring markedly higher than those in clinical medicine,medical laboratory technology,and other disciplines(P＜0.05).Conclusions:The surveyed medical students demonstrated a positive attitude toward innovation and entrepreneurship,yet gaps remained in practical application and resource accessibility.The institution should refine curricula,strengthen industry-academia collaboration,and develop tailored programs based on disciplinary characteristics to enhance students'innovation and entrepreneurship capabilities.

Objective To investigate the relationship between the protective mechanism of dexmedetomidine(Dex)against myocardial ischemia-reperfusion(I/R)injury and cuproptosis.Methods The Langendorff models were con-structed using SD rats(I/R group),which were divided into 4 groups according to different interventions during reperfusion as:sham group,I/R group,Dex group and Dex+ES-Cu group.The left ventricular peak pressure(LVSP)of the rats in the above four groups were continuously monitored in the immediate pre-ischemic period(T0),30 min of reperfusion(T1),60 min reperfusion(T2),90 min reperfusion(T3),2 h of reperfusion(T4).Left ventricular end-diastolic pressure(LVEDP),heart rate(HR),maximum rate of rise of left ventricular pressure(+dp/dtmax)and maximum rate of drop.Subsequently,the extent of myocardial infarction was shown by 1%triphenyltetrazoliumchloride(TTC)staining,and the degree of myocardial fibrosis was assessed by Sirius red staining;Myocardial enzyme profiles,oxidative stress and inflammation indexes were detected by ELISA;Copper ions were detected by copper ion detection kit in myocardial tissues;ATF3,SPI1 and FDX1 protein level expres-sion was detected by Western blot.Results Compared with the sham-operated group,the extent of myocardial in-farction and fibrosis increased in the I/R group(P＜0.05),the level of serum MDA,IL-6,IL-1β,and TNF-α was elevated(P＜0.05),and the activity of SOD and GSH-Px decreased(P＜0.05).The Dex group significantly alleviated the above changes in the I/R group,and compared with the Dex group,in the Dex+ES-Cu group myocardi-al tissue copper ion content at the end of perfusion was increased(P＜0.05).Both ATF3 and SPI1 protein were in-creased and FDX1 protein was decreased(P＜0.05).Conclusions Dex can regulate copper metabolism and improve myocardial ischemia-reperfusion injury(MI/RI)resulted from oxidative stress and inflammation in rat model.

Objective This study aims to compare the efficacy of video stylets and video laryngoscopes in facilitating nasotracheal intubation during oral surgery.Methods A total of 80 patients,aged between 18 and 70 years old,with ASA grade Ⅰ or Ⅱ,scheduled for elective oral surgery under general anesthesia,were randomly assigned to either the video stylet group(Group N)or the video laryngoscope group(Group C),with 40 patients in each group.In Group N,a video stylet was used to shape the tracheal tube at a 90-degree angle,with the shaping position being the vertical distance from the Adam's apple to the nostril.The tube was inserted from the nasal cavity into the throat under direct visualization,and positioned behind the glottis.In Group C,the tube was initially blindly inserted into the nasal cavity without a core.Upon reaching the throat,a video laryngoscope was employed to lift the epiglottis and expose the glottis from the mouth.The tube was then inserted with the aid of intubation forceps or cuff inflation.The primary outcome measure was the intubation time.Additional measures included the time taken for nasal passage,glottis exposure,and the number of intubation attempts and assistant interventions required.Vital signs,including MAP and HR,were recorded at five minutes of quiet rest upon entering the room(T0),during glottis exposure(T1),upon passage of the tube through the glottis(T2),and one minute after the tube entered the trachea(T3).Complications such as epistaxis,oral mucosal bleeding,loose incisors,and postop-erative sore throat were also documented.Results The intubation time and nasal passage time in Group N were significantly shorter than those in Group C(P<0.05).The number of cuff inflations and intubation forceps assisted cases in Group N was significantly lower than in Group C(P<0.05).There were no significant differences between the two groups in terms of glottis exposure time,first successful intubation times,C-L glottis classification,and mandibular lift-assisted intubation(P>0.05).The increase in MAP and HR in Group N at T1 and T2 was signifi-cantly less than in Group C(P<0.05).The number of cases with mild epistaxis in Group N was significantly lower than in Group C(P<0.05).Similarly,the number of cases with loose incisors and oral mucosal bleeding in Group N was significantly less than in Group C(P<0.05).Conclusion Compared to the video laryngoscope,the video stylet-guided nasotracheal intubation results in a shorter intubation time,less damage to the oronasopharynx,eliminates the need for intubation forceps,and reduces the patient's stress and vascular stress response during intubation.

Objective:To make a new simple respirator and observe the oxygen therapy effect of the respirator on patients with severe and critical coronavirus disease 2019 (COVID-19).Methods:Based on the infectivity and hospital requirements of COVID-19, a new simple respirator was designed by the medical staff of the Department of Anesthesiology of the Second Affiliated Hospital of Nanchang University, which was applied on the 22 patients with severe and critical COVID-19 who needed oxygen therapy admitted to the Cancer Center of Tongji Medical College of Huazhong University of Science and Technology from February 15th to March 15th in 2020. The new simple respirator contained two National Utility Model Patents (a respirator: ZL 2015 2 0410623.6, a fluid switch and oxygen suction device: ZL 2017 2 0873509.6), which was mainly composed of anesthesia mask and filter, L-shaped connecting tube, soft breathing bladder, connecting tube and elastic fixing belt. When in use, the anesthesia mask was fixed to the patient's mouth and nose with elastic straps, the connecting tube was inserted into the oxygen meter interface, the oxygen flow was adjusted to 6-10 L/min, and the L-shaped connecting tube was opened immediately after the soft breathing bag was full. The carbon dioxide and excess oxygen in the body was discharged from exhaust port. The oxygen flow was lowered to 2-3 L/min, the patient's respiratory rate (RR) was observed through the soft breathing bag fluctuations, and the oxygen flow was adjusted at any time. The changes of pulse oxygen saturation (SpO 2), RR and heart rate (HR) before and after application of new simple respirator were observed, and the blood gas test results of part of the patients were collected. Results:Twenty-two patients with severe and critical COVID-19 had significantly higher SpO 2 at 10 minutes after application of the new simple ventilator than before application (0.994±0.007 vs. 0.952±0.017, P < 0.01), and RR was significantly lower than that before application (times/min: 27.59±3.63 vs. 29.64±3.81, P < 0.01); after 1 day of application, each index was further improved. All 13 patients who received blood gas analysis indicated no carbon dioxide accumulation. Conclusions:The new simple respirator can significantly improve the oxygen therapy effect of patients with severe and critical COVID-19. At the same time, 2019 novel coronavirus (2019-nCoV) can be filtered through the filter to reduce the formation of aerosol and protect the medical staff and patients.

Objective: To describe the MICM (morphology, immunology, cytogenetics and molecular biology) characteristics of a case of acute myelomonocytic leukemia M 4C . Methods: The medical history data of the case of M 4C admitted to our hospital was reviewed. The results of bone marrow cell morphology, cytochemical stains, bone marrow biopsy, immunophenotype, cytogenetics, molecular test and NGS (next-generation sequencing) of the case were analyzed. Results: The bone marrow smear showed markedly active proliferation of bone marrow cells in which the myelomonocytic cells accounted for 85.6%. Cytochemical stains showed peroxidase (POX) stain partially and weakly positive; specific esterase AS-DCE partially positive; non-specific esterase α-NBE partially positive and smothered by sodium fluoride; non-specific esterase AS-DAE partially positive and smothered by sodium fluoride. Bone marrow biopsy showed hyperproliferative cells and diffused hyperplasia of blasts. Immunophenotype analysis showed that the abnormal cell population was positive for CD11B, CD64, CD56, cMPO, CD33, CD41, CD61, CD38 and CD58, but negative for CD13, CD34, CD117, CD7, CD123, HLA-DR, CD10, CD19, CD20, CD2, CD14, CD235, CD15, CD303, CD304, CD25, cCD79a, cCD3, cCD22, CD1a and TDT. Cytogenetic analysis showed 47, XY, t(9;11) (p22;q23),+mar. The molecular test for leukemia showed MLLT3/KMT2A gene rearrangement. NGS showed NRAS and TET2 mutation. The case was finally diagnosed as AML (acute myelomonocytic leukemia) M 4C with t(9;11)(p22;q23), MLLT3-KMT2A. Conclusion Leukemia M 4C may show the characteristics of both granulocytes and monocytes with complex morphological features. The combined examination of MICM should be necessary for the diagnosis of M 4C with great significance.
