ObjectiveTo identify potential influencing factors of urate crystal deposition at ankle/foot in patients with hyperuricemia （HUA）， and to analyze the predictive value of inflammatory indicators for urate crystal deposition in patients with different traditional Chinese medicine （TCM） syndromes， so as to provide potential reference for clinical risk assessment and individualized TCM intervention. MethodsA retrospective study was carried out with the enrollment of 231 HUA patients from The Third Affiliated People's Hospital of Fujian University of Traditional Chinese Medicine between January 2021 and December 2024. The enrolled patients were further divided into a crystal deposition-positive group （143 cases） and a crystal deposition-negative group （88 cases） according to the results of dual-energy computed tomography （CT）. Sociodemographic data， living habits， serum uric acid levels， and inflammatory indicators of the enrolled patients were collcted， and TCM syndrome differentiation was performed. Furthermore， univariate analysis was used to compare inter-group differences in clinical characteristics. MMultivariate Logistic regression was applied to identify the influencing factors of urate crystal deposition. In addition， the receiver operating characteristic （ROC） curves were plotted to evaluate the predictive efficacy of inflammatory indicators for crystal deposition across different TCM syndromes. ResultsThere were statistically significant inter-group differences in the proportion of males， age， body mass index， proportion of mental labor， rate of low water intake， and rate of high-sugar beverage consumption （P<0.05），whereas no significant difference in low exercise intensity was found between the two groups. Furthermore， compared with the negative group， the positive group had higher serum uric acid level， neutrophil-to-lymphocyte ratio （NLR）， and platelet-to-lymphocyte ratio （PLR）， but lower systemic immune-inflammation index （SIRI） （P<0.05）. Regarding the distribution of TCM syndromes， the positive group was dominated by the dampness-heat accumulation syndrome （55/143，38.46%）， while the negative group was mainly characterized by the phlegm-turbidity obstruction syndrome （44/88，50.00%）. Multivariate Logistic regression analysis revealed that high-sugar beverage consumption， elevated NLR， and elevated PLR were risk factors for urate crystal deposition ［odd ratio （OR） = 8.002， 5.377， 1.034， respectively； 95% CI 1.572-40.732， 2.179-13.270， 1.013-1.054，all P<0.05］， while SIRI was a protective factor （OR = 0.869， 95% CI 0.778-0.971， P<0.05）. In the positive group， patients with the dampness-heat accumulation syndrome exhibited the highest NLR， while the lowest PLR and SIRI， showing statistically significant differences with those of other syndromes （all P<0.05）. In addition， ROC curve analysis indicated that for the dampness-heat accumulation syndrome， the combined "NLR + PLR" model had an area under the curve （AUC） of 0.901 （95% CI 0.850-0.951， P<0.01）， with a sensitivity of 89.1% and a specificity of 79.5%； for the blood stasis-heat obstruction syndrome， the combined "NLR + PLR" model had an AUC of 0.880 （95% CI 0.825-0.934， P<0.01）， with a sensitivity of 100.0% and a specificity of 67.3%； for the liver-kidney Yin-deficiency syndrome， the single PLR model had an AUC of 0.842 （95% CI 0.731-0.952， P<0.01）， with a sensitivity of 83.3% and a specificity of 84.0%. ConclusionUrate crystal deposition in HUA patients exhibits intimate associations with high-sugar beverage consumption as well as elevated NLR and PLR levels. Meanwhile， TCM syndrome differentiation has potential correlation with inflammatory characteristics. The inflammatory indicator-based prediction model constructed based on TCM syndromes exhibits good predictive value.

Lung transplantation is a definitive treatment for end-stage lung disease and can significantly improve patient prognosis. However, postoperative complications such as infection, rejection, ischemia-reperfusion injury and chronic lung allograft dysfunction intertwine to form a complex pathological network, posing persistent challenges to long-term patient survival.

By integrating cutting-edge technologies including single-cell multi-omics, spatial transcriptomics and novel animal models, significant breakthroughs have been achieved in the evolutionary dynamics of drug-resistant infections, molecular mechanisms of immune regulation, programmed cell death, optimization of donor lung protection strategies and early warning of chronic lung allograft dysfunction. This article systematically reviews the representative advances in basic lung transplantation research worldwide in 2025, and deeply analyzes the implications of mechanistic breakthroughs for optimizing diagnosis and treatment strategies, aiming to anchor the direction for innovative breakthroughs and clinical translation in basic lung transplantation research.

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.

COMPERA 2.0 risk stratification has been demonstrated to be useful in patients with precapillary pulmonary hypertension (PH). However, its suitability for patients at risk for post-capillary PH or PH associated with left heart disease (PH-LHD) is unclear. To investigate the use of COMPERA 2.0 in patients with severe aortic stenosis (SAS) undergoing transcatheter aortic valve replacement (TAVR), who are at risk for post-capillary PH, a total of 327 eligible SAS patients undergoing TAVR at our institution between September 2015 and November 2020 were included in the study. Patients were classified into four strata before and after TAVR using the COMPERA 2.0 risk score. The primary endpoint was all-cause mortality. Survival analysis was performed using Kaplan-Meier curves, log-rank test, and Cox proportional hazards regression model. The study cohort had a median (interquartile range) age of 76 (70‒80) years and a pulmonary arterial systolic pressure of 33 (27‒43) mmHg (1 mmHg=0.133 kPa) before TAVR. The overall mortality was 11.9% during 26 (15‒47) months of follow-up. Before TAVR, cumulative mortality was higher with an increase in the risk stratum level (log-rank, both P<0.001); each increase in the risk stratum level resulted in an increased risk of death (hazard ratio (HR) 2.53, 95% confidential interval (CI) 1.54‒4.18, P<0.001), which was independent of age, sex, estimated glomerular filtration rate (eGFR), hemoglobin, albumin, and valve type (HR 1.76, 95% CI 1.01‒3.07, P=0.047). Similar results were observed at 30 d after TAVR. COMPERA 2.0 can serve as a useful tool for risk stratification in patients with SAS undergoing TAVR, indicating its potential application in the management of PH-LHD. Further validation is needed in patients with confirmed post-capillary PH by right heart catheterization.

The anterior cingulate cortex (ACC) has recently been proposed as a key player in the representation of itch stimuli. However, to date, little is known about the contribution of specific ACC interneuron populations to itch processing. Using c-Fos immunolabeling and in vivo Ca²⁺ imaging, we reported that both histamine and chloroquine stimuli-induced acute itch caused a marked enhancement of vasoactive intestinal peptide (VIP)-expressing interneuron activity in the ACC. Behavioral data indicated that optogenetic and chemogenetic activation of these neurons reduced scratching responses related to histaminergic and non-histaminergic acute itch. Similar neural activity and modulatory role of these neurons were seen in mice with chronic itch induced by contact dermatitis. Together, this study highlights the importance of ACC VIP⁺ neurons in modulating itch-related affect and behavior, which may help us to develop novel mechanism-based strategies to treat refractory chronic itch in the clinic.

Objective:To summarize the clinical manifestations of anti-synthetase syndrome (ASS) with interstitial lung disease (ILD) patients with different antibody subtypes and the skeletal muscle pathology of ASS.Methods:A total of 106 ASS-ILD patients admitted to the First Medical Center of Chinese People′s Liberation Army General Hospital from May 11, 2015 to June 25, 2023 were included. Their intramuscular and extramuscular clinical manifestations were collected. The correlation between different antibody subtypes in patients with ASS and the various subtypes of ILD was investigated. The skeletal muscle pathological characteristics of 13 ASS patients were also summarized.Results:Among the 106 ASS-ILD patients, 56 (52.8%) were anti-JO-1 antibody positive, 19 (17.9%) were anti-PL-7 antibody positive, 11 (10.4%) were anti-PL-12 antibody positive, 14 (13.2%) were anti-EJ antibody positive, and 6 (5.7%) were anti-OJ antibody positive. All the patients had ILD [including nonspecific interstitial pneumonia (NSIP), usual interstitial pneumonia (UIP), organizing pneumonia (OP), mixed pneumonia]. In all the patients, 46.2% (49/106) had cardiac damage, 37.7% (40/106) had arthritis, 29.2% (31/106) had myasthenia gravis, 24.5% (26/106) had myalgia, and 19.8% (21/106) had Raynaud′s phenomenon. The incidence of NSIP was 75.0% (42/56) in the anti-JO-1 antibody-positive group, significantly higher than other groups (anti-PL-7 antibody-positive group, 8/19;anti-PL-12 antibody-positive group, 3/11;anti-EJ antibody-positive group, 5/14;anti-OJ antibody-positive group, 2/6; P=0.001). UIP was most common in the anti-PL-7 antibody-positive group (8/19). OP was most frequent in the anti-PL-12 antibody-positive group (5/11). The incidence of arthritis was highest in the anti-JO-1 antibody-positive group (51.8%, 29/56). The anti-Ro-52 antibody-positive rate was significantly higher in the anti-EJ antibody-positive group (12/14) than in the other 4 groups [anti-JO-1 antibody-positive group, 33.9% (19/56); anti-PL-7 antibody-positive group, 10/19; anti-PL-12 antibody-positive group, 6/11; anti-OJ antibody-positive group, 0/6; P=0.001]. ASS skeletal muscle pathology was manifested as necrotizing myopathy pattern (6/13), inflammatory myopathy pattern (4/13), and nonspecific myopathy pattern (3/13). All the 106 patients received methylprednisolone as the basic treatment. Among them, 69 patients (65.1%) received methylprednisolone alone, while 37 patients (34.9%) received combination therapy involving immunosuppressants, whose symptoms improved after treatment. Conclusions:A discernible correlation exists between the clinical manifestations of ASS with ILD and specific antibody subtypes. ASS patients generally respond well to immunotherapy. ASS can manifest as 3 distinct skeletal muscle pathological patterns: necrotizing myopathy pattern, inflammatory myopathy pattern, and nonspecific myopathy pattern.

Conventional surgical management of pelvic fractures entails incision and reduction with internal fixation, a procedure associated with significant bleeding, trauma, and a high surgical risk. The advent of advanced imaging techniques and sophisticated surgical instruments has led to a paradigm shift towards minimally invasive surgery as the prevailing treatment modality for such injuries. The efficacy of reduction is pivotal in determining the clinical prognosis of pelvic fractures, underscoring the importance of enhancing the quality of reduction in the minimally invasive surgery. The advent of 3D printing technology, intelligent orthopaedic surgical robots, mixed reality augmentation technology and high-precision optical localization tracking has catapulted minimally invasive pelvic fracture reduction to the forefront of research in the field of orthopaedics. Studies have demonstrated encouraging outcomes. This paper reviews relevant literature, mainly focusing on the evaluation and measurement, open reduction techniques, minimally invasive closed reduction techniques, and surgical robot assisted reduction techniques in treatment of pelvic fractures, to summarize the technical research progress in minimally invasive closed surgical reduction for pelvic fractures.

Objective Based on data mining,network pharmacology,and molecular docking techniques,the medication patterns and underlying mechanisms of the therapeutic approach of trengthening the spleen,transforming stasis and removing toxins methods(JPHYJD)in treating gastric precancerous lesions(GPL)were analyzed.Methods Initially,data mining was conducted to extract relevant literature on the application of JPHYJD in GPL.An analytical network map was then constructed to get the identification of a representative drug set.In the network pharmacology phase.Active compounds and their targets were retrieved from TCMSP,while disease-related targets specific to GPL were sourced from Gene Cards,OMIM,and TTD.A"drug-disease"target intersection was mapped using bioinformatics platforms,and an"active compound-key target"network was constructed in Cytoscape.Protein-protein interaction(PPI)networks were obtained from the STRING database,and GO and KEGG enrichment analyses were performed to elucidate biological processes and pathways.Preliminary validation was conducted using molecular docking technology.Results 63 prescriptions were analyzed,with Baizhu-Ezhu-Danshen-Baihuashecao identified as the most representative drug set.85 active compounds and 590 predicted targets were discovered,intersecting with 4,726 disease-related targets,resulting in 412 key targets.GO and KEGG enrichment analyses yielded 3,541 enriched terms and 196 pathways,respectively.Key compounds,such as quercetin and alexandrin,targeted pivotal proteins like tumor protein 53(TP53),signal transducer and activator of transcription 3(STAT3),and epidermal growth factor receptor(EGFR)were implicated in regulating critical pathways like PI3K/AKT,exerting therapeutic effects.Molecular docking results demonstrated stable binding interactions between the core active compounds and their targets,reinforcing the predicted interactions.Conclusion This study,integrating data mining,network pharmacology,and molecular docking techniques,successfully elucidated the therapeutic patterns and underlying mechanisms of the JPHYJD approach in GPL treatment.

Objective To explore the lung protective effect of pressure controlled ventilation-volume guaranteed(PCV-VG)combined with driving pressure(DP)guided lung protective ventilation strategy in patients undergoing thoracoscopic and laparoscopic radical esophagectomy.Methods 70 patients scheduled for elective thoracoscopic and laparoscopic radical esophagectomy were allocated into two groups using a random number table method:Conventional lung protective ventilation strategy group(group C)and DP guided lung protective ventilation strategy under PCV-VG mode group(group P),35 case in each group.Peak airway pressure(Ppeak),plateau pressure(Pplat),dynamic compliance(Cdyn)and DP were compared between the two groups at 5 minutes after intubation(T1),30 min after pneumoperitoneum established(T2),just prior to one lung ventilation(OLV)(T3),30 min after OLV(T4),60 min after OLV(T5)and 15 min from recovery of two lung ventilation(TLV)(T6).The blood pressure(BP),heart rate(HR),arterial partial pressure of oxygen(PaO2),partial pressure of carbon dioxide in arterial blood(PaCO2)and pH were recorded before anesthesia(T0),T2,T3,T4,T5 and T6 time points.The occurrence of postoperative pulmonary complications(PPCs)also recorded.Results Compared with group C,Ppeak in group P at T1,T2,T4,T5 and T6 time points was significantly decreased,and Cdyn was obviously increased,the differences were statistically significant(P＜0.05).At the T1,T4,T5 and T6 time points,the DP was lower in group P compared to group C,and Pplat at T6 time point was lower than that in group C,the differences were statistically significant(P＜0.05).At the time points of T4 and T5,the PaO2 in group P was higher than that in Group C,and the PaCO2 at T6 time point was also higher than that in group C,the differences were statistically significant(P＜0.05).The comparison of PaCO2 at T0,T2,T3,T4 and T5 time points of the two groups,the difference was not statistically significant(P＞0.05).Comparison of pH between the two groups,the difference was not statistically significant at all time points(P＞0.05).The systolic blood pressure(SBP)of group P was higher than that of group C at the T4 time point,and the diastolic blood pressure(DBP)was lower than that of group C at T6 time point,and the differences were statistically significant(P＜0.05);There were no significant differences in SBP and DBP at T0,T2,T3 and T5 time points,and HR at each time point between the two groups(P＞0.05).There was no statistically significant difference in the occurrence of PPCs within 7 d after operation between the two groups(P＞0.05).Conclusion DP guided lung protective ventilation strategy under PCV-VG mode can improve intraoperative respiratory mechanics,and increase oxygenation during OLV in patients undergoing thoracoscopic and laparoscopic radical esophagectomy,but it does not significantly affect the incidence of PPCs within 7 d after operation.It is worthy clinical significant.
