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 risk factors for postoperative fever in patients with negative preoperative urine culture undergoing flexible ureteroscopy (fURS), and construct a nomogram prediction model to predict the risk of postoperative fever.Methods:The clinical data of 308 patients who underwent flexible ureteroscopy (fURS) at the Second Affiliated Hospital of Zhengzhou University from January 2019 to March2023, were retrospectively analyzed. Among these patients, there were 235 males and 73 females, with an average age of (46.4±12.1) years old. Additionally, 86 cases had concomitant hypertension, 41 cases had diabetes, and 12 cases had coronary heart disease. A history of urinary stone surgery was present in 57 cases, and 91 cases exhibited severe hydronephrosis. The distribution of stones included 164 cases on the left side and 144 cases on the right side, with 88 cases of renal stones, 124 cases of ureteral stones, and 96 cases of renal-ureteral stones. Among them, 243 cases had ≤2 stones, while 65 cases had >2 stones, with a maximum stone diameter of 12.0 (9.0, 15.0) mm. Urine leukocyte-positive cases were 109, and urine leukocyte-negative cases were 199. Two cases were positive for nitrite, and 308 cases were negative. The occurrence of postoperative fever within 48 hours was recorded, and differences between the fever and non-fever groups were compared. Logistic regression analysis was employed to identify risk factors for post-fURS fever. A nomogram prediction model based on independent risk factors was constructed, and internal validation was conducted using 1 000 bootstrap resamples. The predictive performance of the model was evaluated using receiver operating characteristic (ROC) curves and the area under the curve (AUC). Model stability was assessed using calibration curves.Results:The surgeries for all 308 cases were successfully completed with a median operative time of 60.0 (40.0, 75.0) minutes. Complete stone clearance was achieved in 221 cases. Among them, 14 cases (4.5%) experienced postoperative fever, while 294 cases did not. The fever group had a higher proportion of females [57.1% (8/14) vs. 22.1% (65/294), P=0.007], more cases with comorbid diabetes [50.0% (7/14) vs. 11.6% (34/294), P<0.001], a higher proportion of renal stones [64.3% (9/14) vs. 26.9% (79/294), P=0.022], a lower intraoperative stone clearance rate [42.9% (6/14) vs. 73.1% (215/294), P=0.031], larger stone diameter [15.5 (12.5, 19.3) mm vs. 11.0 (9.0, 15.0) mm, P=0.004], longer operative time [87.5 (58.8, 106.3) min vs. 55.0 (40.0, 75.0) min, P<0.001], higher platelet count [267.0 (225.8, 354.0) ×10 9/L vs. 233.0 (197.8, 272.0) ×10 9/L, P=0.026], lower creatinine levels [67.5 (52.5, 72.3) umol/L vs. 73.0 (62.0, 84.0) umol/L, P=0.026], and a higher platelet lymphocyte ratio [148.8 (118.3, 189.3) vs. 119.5 (93.2, 156.0), P=0.030]. Results of univariate analysis showed that female gender, diabetes, stone location, incomplete stone clearance, maximum stone diameter, operative time, platelet count, creatinine, platelet lymphocyte ratio, and positive nitrite in urine (all P<0.05)were risk factors for postoperative fever. Multivariate regression analysis revealed that female gender ( OR=11.073, 95% CI 1.623-75.521, P=0.014), diabetes ( OR=5.995, 95% CI 1.441-24.952, P=0.014), and operative time ( OR=1.024, 95% CI 1.003-1.046, P=0.024) were independent risk factors for post-fURS fever. The nomogram exhibited excellent predictive performance (AUC=0.866, 95% CI 0.781-0.935), and the calibration curve demonstrated good consistency. Conclusions:Female gender, longer operative time, and diabetes are risk factors for post-fURS fever in patients with preoperative negative urine culture. The nomogram demonstrates excellent predictive performance.

Henoch-Sch?nlein purpura is also known as IgA vasculitis. The kidney involvement, namely Henoch-Sch?nlein purpura nephritis (HSPN), is one of IgA vasculitis's main clinical manifestations. Galactose-deficient IgA1 plays an important role in the pathogenesis of HSPN, which not only is similar to the "four-hits hypothesis" of IgA nephropathy, leading to IgA1 deposit in the mesangial region of the kidney, but also is closely related to inflammation with more complicated compositions of its immune complex. Therefore, abnormal glycosylation of IgA1 is expected to be a biomarker for diagnosis and prediction of HSPN pathogenesis, disease activity determination and prognosis prediction. Here, the paper reviews the research progress on the pathogenesis and clinical application of abnormal glycosylation of IgA1 in HSPN.

Objective:To explore the clinical value of antegrade transabdominal nasobiliary duct placement in the treatment of fine diameter choledocholithiasis in the elderly.Methods:From June 2021 to June 2022, 60 elderly patients with fine diameter common bile duct stones who were treatment in the Shandong Chengwu County People′s Hospital were enrolled. All patients underwent laparoscopic common bile duct exploration (LCBDE), 28 patients in the experimental group were underwent antegrade transabdominal placement of nasal bile ducts, 32 patients in the control group were treated with T-tube drainage. The operative index, postoperative complications and total medical expenses, postoperative patient satisfaction were compared between the two groups.Results:The operation was successful in both groups, and no conversion to laparotomy or death occurred. The indwelling time of common bile duct drainage, postoperative hospital stay in the experimental group were shorter than those in the control group, the incidence of postoperative pain was lower than that in the control group, the postoperative patient satisfaction was higher than that in the control group: (6.46 ± 1.04) d vs. (33.63 ± 1.19) d, (8.11 ± 0.74) d vs. (10.38 ± 1.54) d, 3.6%(1/28) vs. 21.9%(7/32), (9.21 ± 0.83) scores vs. (7.56 ± 0.62) scores, there were statistical differences ( P<0.05). The surgical time, postoperative activity time, gastrointestinal function recovery time and total medical expenses between the two groups had no statistical differences( P>0.05). The postoperative complications between the two groups had no statistical differences ( P>0.05). Conclusions:Anterior transabdominal nasobiliary duct placement can shorten the retention time and hospitalization time of the common bile duct drainage tube, reduce the incidence of postoperative complications, and promote rapid recovery. It is a safe and effective surgical method.

Activation of nuclear factor erythroid 2-related factor 2(Nrf2)by Kelch-like ECH-associated protein 1(Keap1)alkylation plays a central role in anti-inflammatory therapy.However,activators of Nrf2 through alkylation of Keap1-Kelch domain have not been identified.Deoxynyboquinone(DNQ)is a natural small molecule discovered from marine actinomycetes.The current study was designed to investigate the anti-inflammatory effects and molecular mechanisms of DNQ via alkylation of Keap1.DNQ exhibited signif-icant anti-inflammatory properties both in vitro and in vivo.The pharmacophore responsible for the anti-inflammatory properties of DNQ was determined to be the α,β-unsaturated amides moieties by a chemical reaction between DNQ and N-acetylcysteine.DNQ exerted anti-inflammatory effects through activation of Nrf2/ARE pathway.Keap1 was demonstrated to be the direct target of DNQ and bound with DNQ through conjugate addition reaction involving alkylation.The specific alkylation site of DNQ on Keap1 for Nrf2 activation was elucidated with a synthesized probe in conjunction with liquid chromatography-tandem mass spectrometry.DNQ triggered the ubiquitination and subsequent degra-dation of Keap1 by alkylation of the cysteine residue 489(Cys489)on Keap1-Kelch domain,ultimately enabling the activation of Nrf2.Our findings revealed that DNQ exhibited potent anti-inflammatory capacity through α,β-unsaturated amides moieties active group which specifically activated Nrf2 signal pathway via alkylation/ubiquitination of Keap1-Kelch domain,suggesting the potential values of targeting Cys489 on Keap1-Kelch domain by DNQ-like small molecules in inflammatory therapies.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Aim To explore the mechanism of hydroxy-a-sanshool in the treatment of diabetic cardiomyopathy ( DCM) based on label-free quantitative proteomics detection technique. Methods DCM model was established by high fat diet and intraperitoneal injection of streptozotocin ( STZ) . They were divided into control group ( CON group ) , diabetic cardiomyopathy group (DCM group) and hydroxy-a-sanshool treatment group ( DCM + SAN group) . The cardiac function of mice was evaluated by echocardiography, the myocardial morphology was observed by pathology staining, the protective mechanism of hydroxy-a-sanshool on diabetic cardiomyopathy was speculated by proteomic technique , and the expression level of cAMP/PKA signaling pathway and key proteins were verified by Western blotting. Results Cardiac ultrasound and pathology staining showed that hydroxy-a-sanshool had protective effect on the heart of DCM mice. Label-free quantitative proteomic analysis was carried out between DCM + SAN group and DCM group, and 160 differential pro-teins were identified by proteomics, in which 127 proteins were up-regulated and 33 proteins were down regulated ; GO secondary functional annotations showed the biological process, molecular function and cellular component; KEGG enrichment analysis showed that cAMP signaling pathway was the most abundant; protein interaction network showed that PKA as the central node interacted with many proteins in the cAMP signaling pathway. Western blot showed that the relative expression of с AMP, PKA protein in DCM group was significantly lower than that in CON group ( P < 0. 05 ) , while the relative expression of cAMP, PKA protein in DCM + SAN group was significantly higher than that in DCM group ( P < 0. 05 ) . Conclusions Hydroxy-a-sanshool has protective effect on heart function of mice with diabetes, which plays a role through cAMP signaling pathway.

Hepatic ascites is one of the common and difficult complications in the decompensated stage of liver cirrhosis， and its incidence is increasing. In clinical practice， the prognosis of patients with hepatic ascites after surgery is worse， and the disease is recurrent. Traditional Chinese medicine （TCM） has certain advantages in treating hepatic ascites. However， there is no uniform standard for the preparation of animal models of hepatic ascites in accordance with TCM evidence. Therefore， this paper summarized the literature on animal models of hepatic ascites and analyzed the existing animal models of hepatic ascites based on the clinical diagnostic criteria of hepatic ascites in TCM and western medicine. The results show that the commonly used modeling methods for hepatic ascites mainly include the single-factor method， composite factor induction method， surgical method， and immunization method. Most of them are guided by western medicine theories， and their pathogenic mechanisms are mostly consistent with those of western medicine and are different from TCM evidence. Therefore， it is suggested that TCM intervening factors should be imposed in the process of model preparation， so as to prepare an animal model of hepatic ascites that meets the clinical evidence characteristics of TCM and western medicine.
