Objective To explore the technical process and clinical application of laparoscopic combined upper midline incision minimally invasive liver transplantation. Methods A retrospective analysis was conducted on 30 cases of laparoscopic combined upper midline incision minimally invasive liver transplantation. The cases were divided into cirrhosis group (15 cases) and liver failure group (15 cases) based on the primary disease. The surgical and postoperative conditions of the two groups were compared. Results All patients successfully underwent laparoscopic "clockwise" liver resection, with no cases of passive conversion to open surgery or intolerance to pneumoperitoneum. In 6 cases, the right lobe was relatively large, and the right hepatic ligaments could not be completely mobilized. One case required an additional reverse "L" incision during open surgery. All patients successfully completed the liver transplantation, with no major intraoperative bleeding, cardiovascular events, or other occurrences in the 30 patients. The model for end-stage liver disease (MELD) score in the cirrhosis group was lower than that in the liver failure group (P<0.001). There were no statistically significant differences between the two groups in terms of age, surgical time, blood loss, anhepatic phase, or cold ischemia time (all P>0.05). During the perioperative period, there was 1 case of hepatic artery embolism, 1 case of portal vein anastomotic stenosis, no complications of hepatic vein and inferior vena cava, and 3 cases of biliary anastomotic stenosis, all of which occurred in the liver failure group. Conclusions In strictly selected cases, the minimally invasive liver transplantation technique combining laparoscopic hepatectomy with upper midline incision for graft implantation has the advantages of smaller incisions, less bleeding, relatively easier operation, and faster postoperative recovery, which is worthy of clinical promotion and application.

OBJECTIVE To explore the clinical characteristics of the neonates with early-onset sepsis caused by Listeria monocytogenes and analyze the risk factors for adverse treatment outcomes.METHODS A total of 16 neo-nates with early-onset sepsis caused by L.monocytogenes who were treated in neonatology department of the Affili-ated Suzhou Hospital of Nanjing Medical University from Jan.2012 to Dec.2023 were recruited as the research subjects.The clinical data and the results of laboratory test and drug susceptibility testing were collected from the neonates,and the risk factors for the adverse prognosis were analyzed.RESULTS Totally 14 neonates were born in the hospital,and the incidence rate was 6.7/100,000;13 cases were preterm infants,accounting for 81.25％.The peak of the onset ranged between May and November.Most of the 16 neonates showed clinical symptoms instantly after the birth,and the major manifestations included gasping and moaning(12 cases),hypotonia(11 cases),pale skin(10 cases)and poor response(9 cases).Totally 14 neonates showed the rise of C-reactive protein(CRP)in varying degree within 6 hours after the birth.In terms of the treatment outcomes,9 cases were cured and dis-charged,2 cases were improved and discharged,and 4 cases died.One of another cases was improved and died due to poor prognosis after against-advice discharge.There were significant differences in the decline of base excess,septic shock,use of sensitive antibiotics in early stage,invasive mechanical ventilation and peak value of CRP be-tween the survival group and the death group(P＜0.05).All of the L.monocytogenes were tested resistant to ce-foxitin,6 to ampicillin,6 to vancomycin,8 to linezolid.CONCLUSIONS The early-onset sepsis caused by L.mono-cytogenes is common among the preterm neonates and is prevalent in summer and autumn.Most of the cases show the symptoms instantly after the birth,the clinical manifestations are usually severe,and the mortality rate is high.The pregnant women who are suspected for L.monocytogenes infection before the delivery can be treated with penicillin,the neonates can be treated with the first choice of penicillin or ampicillin,and the severe cases can be treated with combination of vancomycin and linezolid.

Aim To explore the possible regulatory effect of leptin on acyl-CoA synthetase long chain fami-ly member ACSL5 and their effect on migration and in-vasion of breast cancer cell,and to explore the underly-ing mechanism.Methods The expression of leptin receptor was detected by immunofluorescence assay.The migration and invasion ability of MCF-7 cells were detected by wound healing assay and Transwell assay respectively.The downstream target gene of leptin was analyzed by PCR microarray data.The expression of ACSL5 in breast cancer and its correlation with the staging and prognosis of breast cancer patients were as-sessed uing bioinformatics methods.The expression of ACSL5 in MCF-7 cells treated with different concentra-tions of leptin was detected using real time fluorescence quantitative polymerase chain reaction(RT-qPCR).Overexpressing ACSL5 was constructed by lentiviral transfection;the expressions of EMT related proteins,AMPK-α and p-AMPK-α were detected by Western blot.Results Leptin promoted breast cancer cell mi-gration and invasion and EMT.ACSL5 was significant-ly low expressed in breast cancer and related to progno-sis.Leptin downregulated the expression of ACSL5 through OBR.Leptin activated AMPK pathway to downregulate ACSL5 and promote migration,invasion and EMT of breast cancer cells.Conclusions Leptin may promote the migration,invasion and EMT of breast cancer by downregulating ACSL5 through activating AMPK pathway.

OBJECTIVE To analyze the clinical characteristics and pathogens for mixed infections in children with pertussis,so as to references for clinical diagnosis and treatment.METHODS A retrospective analysis was conduc-ted on the clinical data of 350 children diagnosed with pertussis and hospitalized in Wuhan Children's Hospital from Jan.2022 to Dec.2023.The clinical characteristics,peak white blood cell count,peak lymphocyte ratio,high-sensitivity C-reactive protein or C-reactive protein,procalcitonin and complications were compared between different age groups,as well as between the single infection group and the mixed infection group.RESULTS Mixed infections were observed in 291 children(83.14％),predominantly viral(63.43％,222/350),with human rhinovirus/enterovirus being the most common(32.57％,114/350).For children aged＜6 months,6 months to＜1 year and 1 to＜3 years,the incidence of family contact history of cough,panting,hasty breathing,respira-tory failure,peak white blood cell count and peak lymphocyte ratio were all higher than those aged 3 to＜6 years and≥6years(all P＜0.05).The incidence of post-cough vomiting was higher in children aged 6 months to＜1 year and 1 to＜3 years compared to other age groups(P＜0.05).The length of hospital stay decreased with in-creasing age(P＜0.05).The proportions of children with paroxysmal spasmodic cough,post-cough cyanosis,post-cough flushing,coughing spells,inspiratory three concave sign,pneumonia and pulmonary phlegm rales all generally decreased with age(all P＜0.05).Nodding respiration was only observed in children aged＜1 year(P＜0.05).The incidence of fever,co-infection with bacteria and Mycoplasma pneumoniae infection was higher in children aged 6 months to＜1 year,1 to＜3 years,3 to＜6 years and ≥ 6 years compared to those aged＜6 months(all P＜0.05).The incidence of fever was higher in the mixed infection group than that in the single in-fection group(P＜0.05).Children in the single infection group had longer hospital stays,higher incidence of par-oxysmal spasmodic cough,nocturnal cough,post-cough flushing,coughing spells,pulmonary phlegm rales and higher peak lymphocyte ratio(all P＜0.05).The incidence of paroxysmal spasmodic cough was higher in the sin-gle infection group for children aged＜3 months(P＜0.05).CONCLUSIONS The younger children with pertussis have a higher proportion of family contact history of cough and are more prone to clinical manifestations such as paroxysmal spasmodic cough,post-cough vomiting,post-cough cyanosis,and pneumonia.They also have higher peak white blood cell counts,peak lymphocyte ratios and longer hospital stays.As children'age increased,the in-cidence of fever,bacterial,and mycoplasma infections also increased.The types of pathogens in mixed infections varies with patients' age and pertussis mixed infections may mask typical clinical symptoms.

Objective To evaluate the value of tripartite motif-containing protein 21(TRIM21)mRNA expression in alveolar macrophages for the serverity and prognosis of patients with severe pneumonia complicated by acute respiratory distress syndrome(SP-ARDS).Methods A retrospective analysis was conducted on 42 SP-ARDS patients(SP-ARDS group)and 15 outpatient healthy controls(control group)admitted to the Department of Respiratory and Critical Care Medicine,Jinling Hospital Affilicated to Medical School of Nanjing University,from November 2023 to June 2024.Bronchoalveolar lavage fluid was collected,and alveolar macrophages were isolated.The expression levels of TRIM21 mRNA were quantified using qPCR.Differences in TRIM21 mRNA expression levels,clinical characteristics,and relevant laboratory test results were compared between the two groups.Correlations between TRIM21 mRNA expression and SP-ARDS severity,28-day mortality,inflammatory indicators,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)scores,duration of mechanical ventilation,and ICU stay were analyzed using Pearson or Spearman correlation analysis.Logistic regression analysis was used to identify risk factors for 28-day mortality,and the predictive value of each factor was evaluated using receiver operating characteristic(ROC)curves.Results Compared with control group,the expression levels of TRIM21 mRNA,white blood cell counts,neutrophil-to-lymphocyte ratio(NLR),and C-reactive protein(CRP),and procalcitonin(PCT)levels increased(P<0.05),and hemoglobin levels decreased(P<0.05)in SP-ARDS group.No significant differences were observed in gender,age,smoking history,alcohol consumption,underlying disease history,and platelet count between the two groups(P>0.05).TRIM21 mRNA expression level in SP-ARDS patients was positively correlated with ARDS severity(P<0.05).Additionally,non-survivors within 28 days had a significantly higher expression level of TRIM21 mRNA compared to survivors(P<0.001).Correlation analysis indicated that the relative expression level of TRIM21 mRNA in SP-ARDS patients was positively correlated with CRP(r=0.309,P<0.05),NLR(r=0.422,P<0.01),PCT(r=0.561,P<0.001),APACHE Ⅱ score(r=0.615,P<0.001),and duration of mechanical ventilation(r=0.665,P<0.001).Logistic regression analysis revealed that elevated expression levels of TRIM21 mRNA(OR=2.886,P=0.043)and higher APACHE Ⅱ scores(OR=1.546,P=0.037)were independent risk factors for 28-day mortality in SP-ARDS patients.The areas under the ROC curves(AUCs)for predicting 28-day mortality using TRIM21 mRNA expression level and APACHE Ⅱ score were 0.889 and 0.874,respectively,with optimal cut-off values of 5.21 and 20.5 points,respectively.The combined AUC for prediction was 0.962.Conclusion Increased TRIM21 mRNA expression in alveolar macrophages of SP-ARDS patients is positively correlated with disease severity and may serve as a potential predictive marker for 28-day survival in SP-ARDS patients.

Objective To explore the application value of a holistic nursing model based on the Delphi method in patients with acute myocardial infarction(AMI).Methods A total of 110 AMI patients treated at Diqing Shangri-La People's Hospital in Yunnan Province from January 2019 to January 2020 were enrolled and divided into a control group and an observation group,with 55 patients in each,based on their admission order.The control group received routine nursing care,while the observation group received holistic nursing model intervention based on Delphi in addition to the routine nursing care.After 6 months of nursing,the left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),left ventricular ejection fraction(LVEF),general self-efficacy scale(GSES)score,complications,and changes in nursing satisfaction were compared and analyzed between the two groups.Results(1)After nursing,the LVEF significantly increased and the LVEDV and LVESV significantly decreased in both groups;the increase in LVEF was more significant,and the decrease in LVEDV and LVESV was more pronounced in the observation group(P<0.05);(2)The GSES scores of patients in both groups improved compared to before nursing,with a more significant improvement in the observation group(P<0.05);(3)The incidence of adverse events during hospitalization was lower in the observation group than in the control group(P<0.05);(4)The satisfaction rate was higher in the observation group than in the control group after nursing(P<0.05).Conclusion The application of a holistic nursing model based on Delphi in AMI patients can effectively improve cardiac function and self-management efficacy,reduce the incidence of complications,and enhance nursing satisfaction,demonstrating high feasibility.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Objective: Data on syncopal donation-related vasovagal reaction (DRVR) collected from 74 blood centers between 2020 and 2023 was statistically analyzed to provide a reference for developing preventive strategies against syncopal DRVR. Methods: Data on blood donation adverse reactions and basic information of donors from 2020 to 2023 were collected through the information management system at monitoring sentinel sites. Statistical analysis was performed on the following aspects of syncopal DRVR: characteristics of donors who experienced syncope, reported incidence, triggers, duration, presence and occurrence time of syncope-related trauma, clinical management including outpatient and inpatient treatment, and severity grading. Results: From 2020 to 2023, 45 966 donation-related adverse reactions were recorded. Of these, 1 665 (3.72%) cases were syncopal DRVR. The incidence of syncopal DRVR decreased with age, being the highest in the 18-22 age group. Incidence was significantly higher in female donors than male donors, in first-time donors than repeat donors, and in university and individual donors than group donors (all P<0.05). There was no statistically significant difference among different blood donation locations (P>0.05). The top three triggers were tension, fatigue, and needle phobia or fear of blood. Among syncopal DRVR cases, 60.36% occurred during blood collection, 87.63% lasted for less than 60 seconds, and 5.05% were accompanied by trauma. Notably, 57.14% of these traumas occurred after donor had left the blood collection site. Syncope severity was graded based on required treatment: grade 1 (fully recovered without treatment, 95.50%); grade 2 (recovered after outpatient treatment, 4.02%); and grade 3 (recovered after inpatient treatment, 0.48%). Conclusion: By analyzing the data of syncopal DRVR cases, it is possible to provide a reference for formulating blood donor safety policies.

Objective To explore the feasibility and clinical experience of the middle hepatic vein splitting-reconstruction technique in split liver transplantation from low-age donor livers. Methods A retrospective analysis was conducted on the cases of two low-age donor livers that underwent middle hepatic vein splitting-reconstruction, which were transplanted into four child recipients at the Liver Transplantation Center of the Third Affiliated Hospital of Sun Yat-sen University from January 2017 to July 2023. The surgical and postoperative conditions were summarized and analyzed. Results Donor 1 was a 6-year-old and 4-month-old girl with a body weight of 21 kg, and the obtained donor liver weighed 496 g. After splitting, the left and right liver weights were 201 g and 280 g, and transplanted into a 9-month-old boy weighing 6.5 kg and a 9-month-old boy weighing 7.5 kg, respectively. The graft to recipient weight ratio (GRWR) was 3.09% and 3.73%, respectively. Donor 2 was a 5-year-old and 8-month-old boy with a body weight of 19 kg, and the donor liver weighed 673 g. After splitting, the left and right liver weights were 230 g and 400 g, and transplanted into a 13-month-old girl weighing 9.5 kg and a 15-month-old boy weighing 12 kg. The GRWR was 2.42% and 3.33%, respectively. Both donor livers were split ex vivo, with the middle hepatic vein being completely split in the middle and reconstructed using allogeneic iliac vein and iliac artery vascular patches. According to GRWR, none of the 4 transplant livers were reduced in volume. Among the 4 recipients, one died due to postoperative portal vein thrombosis and non-function of the transplant liver, while the other three cases recovered smoothly without early or late complications. Regular follow-up was conducted until July 31, 2023, and liver function recovered well. Conclusions Under the premise of detailed assessment of the donor liver and meticulous intraoperative operation, as well as matching with suitable child recipients, low-age donor livers may be selected for splitting. The complete splitting and reconstruction of the middle hepatic vein in the middle may effectively ensure the adequate venous return of the left and right liver and provide sufficient functional liver volume.
