This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

Liver failure is a common severe syndrome of liver diseases with high mortality. The function and structural integrity of the intestinal barrier as an entity are closely associated with the development and progression of liver failure. The cGAS-STING signaling pathway can participate in innate immune response by recognizing DNA produced by pathogen invasion and host cell damage and inducing the production of type I interferon. Numerous studies have shown that activation of the cGAS-STING pathway can significantly impact the cellular structure， mucosal components， and commensal bacteria of the intestinal barrier. This article reviews the interplay between the cGAS-STING signaling pathway and intestinal barrier disruption in liver failure， in order to provide novel insights for the clinical management of liver failure.

Lung transplantation is the ultimate therapeutic option for end-stage pulmonary diseases such as interstitial pneumonia, chronic obstructive pulmonary disease and pneumoconiosis. Currently, the shortage of allogeneic lung donors significantly limits the opportunity for end-stage lung disease patients to receive lung transplantation. In recent years, with the rapid development of biomedical engineering technologies, especially the major breakthroughs in genetic modification and cloning, xenogeneic lung transplantation has shown important potential for clinical translation. Among them, genetically modified pigs have become the most promising xenogeneic lung source due to the close similarity of organ size and physiological characteristics to humans, and the ability to perform targeted gene knockouts (such as α-Gal antigen knockout) to reduce the occurrence of hyperacute rejection. This article focuses on the research progress of porcine xenogeneic lung transplantation, systematically reviews the latest achievements and challenges in animal experiments and human trials, and introduces the technical experience accumulated by Shenzhen Third People's Hospital in the porcine-to-monkey xenogeneic lung transplantation model, in the hope of providing practical references for future research in this field.

Enhanced recovery after surgery (ERAS) is a series of perioperative optimization measures based on evidence-based medicine aimed at achieving rapid recovery. Existing studies have shown that ERAS can effectively reduce surgical stress, decrease the incidence of complications, shorten hospital stays, save medical costs, and improve patient satisfaction. Although lung transplantation techniques have become increasingly mature, lung transplant recipients still have a high incidence of complications during perioperative period. To further improve the perioperative survival rate of lung transplant recipients, introducing ERAS concept into the perioperative management strategy of lung transplantation is of great significance for reducing incidence of perioperative complications, promoting rapid recovery and long-term survival of lung transplant recipients. This article discusses the advances in application of ERAS concept in the perioperative management of lung transplantation, aiming to provide references for optimizing the perioperative management of lung transplant recipients and reducing perioperative complications.

Objective To investigate the early diagnostic value of serum double cortin-like kinase 1(DCLK1),latent transforming growth factor binding protein 2(LTBP2)combined with transvaginal real-time shear wave elastography(SWE)for cervical cancer.Methods A total of 155 patients with cervical lesions treated in our hospital from August 2021 to December 2022 were selected as the research objects.Seventy-five patients with cervical cancer(the cervical cancer group)and 80 patients with cervical intraepithelial neoplasia(the CIN group)were diagnosed by surgical pathology,another 80 volunteers without cervical related diseases who participated in physical examinations at our hospital during the same period were selected as the control group.All subjects of each groups underwent serum DCLK1 and LTBP2 levels detection and transvaginal SWE examination.Receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of serum DCLK1 and LTBP2 for cervical cancer;the diagnostic value of serum DCLK1 and LTBP2 combined with transvaginal SWE for cervical cancer was analyzed by fourfold table analysis.Results The serum levels of DCLK1 and LTBP2 of patients in the cervical cancer group were obviously higher than those in the CIN group and the control group(P<0.05).Compared with before surgery,the serum levels of DCLK1 and LTBP2 1,3,and 6 months after surgery in cervical cancer patients gradually decreased,and there were statistical differences in pairwise comparisons at each time point(P<0.05).The area under the curve of serum DCLK1 and LTBP2 for diagnosing cervical cancer were 0.868 and 0.754,respectively,with sensitivity of 86.67% and 78.67%,specificity of 81.25% and 60.00%,and optimal cutoff values of 1.49 ng/mL and 19.02 μg/mL.The maximum and average elastic modulus of lesion tissue in the cervical cancer group were obviously higher than those in the CIN group(P<0.05).The positive rates of serum DCLK1,serum LTBP2,and transvaginal SWE in the diagnosis of cervical cance were 86.67%,78.67%,and 82.67%,respectively,which were consistent with the gold standard(Kappa=0.624,0.501,0.673,P<0.001),and the positive rate of the combination of them in the diagnosis of cervical cancer was 97.33%,which was highly consistent with the gold standard(Kappa=0.846,P<0.001).The sensitivity and accuracy of the three combined diagnosis were obviously higher than those of the single indicator diagnosis of serum DCLK1,LTBP2,and transvaginal SWE,the specificity of the three combined diagnosis was obviously higher than that of the single indicator diagnosis of serum DCLK1 and LTBP2,the misdiagnosis rate of the three combined diagnosis was obviously lower than that of the single indicator diagnosis of serum DCLK1 and LTBP2,and the differences were all statistically significant(P<0.05).Conclusion Serum DCLK1 and LTBP2 combined with transvaginal SWE has high application value in the diagnosis of cervical cancer,which can further improve the sensitivity and accuracy of diagnosis,and reduce the misdiagnosis rate.

Cornus officinalis,a medicinal and edible plant known for its liver-nourishing properties,has shown promise in inhibiting the activation of hepatic stellate cells(HSCs),crucial indicators of hepatic fibrosis,especially when processed by high pressure wine steaming(HPWS).Herein,this study aims to investigate the regulatory effects of cornus officinalis,both in its raw and HPWS forms,on inflammation and apoptosis in liver fibrosis and their underlying mechanisms.In vivo liver fibrosis models were established by subcutaneous injection of CCl4,while in vitro HSCs were exposed to transforming growth factor-β(TGF-β).These findings demonstrated that cornus officinalis with HPWS conspicuously ameliorated his-topathological injury,reduced the release of proinflammatory factors,and decreased collagen deposition in CCl4-induced rats compared to its raw form.Utilizing ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer(UHPLC-QTOF-MS)combined with network analysis,we identified that the pharmacological effects of the changed components of cornus officinalis before and after HPWS,primarily centered on the adenosine phosphate(AMP)-activated protein kinase(AMPK)pathway.Of note,cornus officinalis activated AMPK and sirtuin 3(SIRT3),promoting the apoptosis of activated HSCs through the caspase cascade by regulating caspase3,caspase6 and caspase9.small interfering RNA(siRNA)experiments showed that cornus officinalis could regulate AMPK activity and its mediated-apoptosis through SIRT3.In conclusion,cornus officinalis exhibited the ability to reduce inflammation and apoptosis,with the SIRT3-AMPK signaling pathway identified as a potential mecha-nism underlying the synergistic effect of cornus officinalis with HPWS on anti-liver fibrosis.

Objective To construct a prediction model for postoperative healthcare-associated infection(HAI)in elderly patients with hip fracture,analyze the economic burden,provide a reference and basis for the development of clinical prevention and control programs.Methods 627 elderly patients who underwent hip fracture surgery in a hospital from January 1,2017 to May 31,2023 were selected as the study subjects.Patients were randomly divided into a modeling group and a validation group at a 7:3 ratio.A logistic regression prediction model was constructed based on data from the modeling group,the discriminant and consistency of the model were evaluated by receiver ope-rating characteristic(ROC)curve and Hosmer-Lemeshow test,and the direct economic burden of postoperative HAI in patients was analyzed with 1∶1 propensity score matching(PSM).Results The incidence of postoperative HAI in elderly patients with hip fracture surgery was 12.1％,with pulmonary infection being the most common(52.6％).Logistic regression analysis showed that male,old age,perioperative disturbance of consciousness,gradeⅣ of American Society of Anesthesiologists(ASA)classification,low albumin level,and intensive care unit(ICU)admission were all independent risk factors for postoperative HAI in patients(all P＜0.05).There was good model discrimination and consistency between the training and validation groups in predicting the risk of postoperative HAI.The direct economic burden of postoperative HAI in patients was 7 927.4 Yuan,of which the burden of wes-tern medicine was the largest(3 139.7 Yuan).HAI prolonged patients hospitalization time by 3.6 days.Conclusion Postoperative HAI increases the economic burden of patients,the nomogram model constructed in this study can effectively predict the risk of postoperative HAI in patients,which can provide a basis for the early identification,as well as the implementation of targeted preventive and diagnostic measures for high-risk patients in the clinic.
