Objective To explore the effect of pregabalin on sleep of patients after video-assisted thoracic surgery(VATS).Methods 120 cases of patients undergoing VATS under general anesthesia were randomly divided into 75 mg pregabalin group(group A),150 mg pregabalin group(group B),and placebo group(group C),with 40 patients in each group.On the night of the operation,the morning and evening of the first day and the second day after the operation,the patients in the three groups were given one tablet of pregabalin(75 mg),one tablet of placebo with the same shape and smell,two tablets of pregabalin(150 mg)and two tablets of placebo with the same shape and smell respectively.Athens insomnia scale(AIS)was used to evaluate the incidence of postoperative sleep disturbance(PSD)on the night of operation,and the patients'sleep quality every night from one night before operation to the 2nd day after operation was assessed using the St.Mary's Hospital sleep questionaire(SMH).Pittsburgh sleep quality index(PSQI)was used to evaluate the patients'sleep quality one day before the operation,7 days after operation,and 1 month after the operation.The digital rating scale(NRS)was used to evaluate the patients'pain at the incision and the surgical side.The remedial analgesia,incidence of adverse events in the 72 h postoperative period,and patient satisfaction score were recorded.Results The incidence of PSD in group A,group B and group C was 45.0％,42.5％and 72.5％,respectively,the incidence of group A and group B was significantly lower than in group C(group A,B and C compared in pairs,P＜0.016 7).The SMH scores in group A and group B were significantly higher than in group C on the day of operation,the first day and the second day after operation(group A,B and C compared in pairs,P＜0.016 7).The incidence of NRS scores in groups A and B at the incision and postoperative remedial analgesia was significantly lower than in group C on postoperative day 1 and postoperative day 2(group A,B and C compared in pairs,P＜0.016 7).There was no statistically significant difference in the pain scores at the incision and shoulder among the three groups at the remaining time points.The postoperative patient satisfaction scores were significantly higher in group A and group B than in group C(P＜0.01).The incidence of dizziness in group B was significantly higher than in the other two groups(P＜0.016 7).Conclusion Oral administration of pregabalin(75 mg/150 mg)for 3 days after VATS can reduce the incidence of PSD and improve the quality of sleep that night,but oral administration of 150 mg pregabalin may increase the incidence of dizziness.

Background::Ebstein’s anomaly (EA) is a rare and complex congenital heart anomaly, and the effect of surgical treatment is not ideal. This study aims to introduce our experience in management strategies, surgical techniques, and operative indications for patients with Ebstein’s anomaly.Methods::A retrospective study of 258 operations was performed in 253 patients by the same cardiac surgeon in The First Hospital of Tsinghua University between March 2004 and January 2020. 32 patients had previously received cardiac surgery in other hospitals. The clinical data including diagnosis, operative indications, techniques, pathological changes, and survival rates were collected and analyzed.Results::Anatomical correction was performed in 203 (78.7%) operations, 1? ventricle repair in 38 (14.7%) operations, tricuspid valve repair only in four operations (1.6%), tricuspid valve replacement in ten (3.9%), total cavopulmonary connection (TCPC) in two (0.8%), and Glenn operation in one operation (0.4%). Reoperation was performed in five patients (2.0%) during hospitalization. Among them, tricuspid valve replacement was performed in one patient, 1? ventricle repair in two patients, and tricuspid valve annulus reinforcement in two patients. Five patients died with an early mortality rate of 2.0%. Complete atrioventricular conduction block was complicated in one patient (0.4%). A total of 244 patients was followed up (four in the 253 patients lost) with a duration of 3.0-168.0 (87.6 ± 38.4) months. Cardiac function of 244 patients improved significantly with mean New York Heart Association (NYHA) functional class recovery from 3.5 to 1.1. The mean grade of tricuspid valve regurgitation improved from 3.6 to 1.5. Three late deaths (1.2%) occurred. The survival rates at five and ten years after surgery were 98.6% and 98.2%, respectively. Reoperation was performed in five patients (2.0%) during the follow-up period.Conclusion::Based on our management strategies and operative principles and techniques, anatomical correction of EA is capable of achieving excellent long-term results, and low rates of TCPC, 1? ventricle repair and valvular replacement.

Background::Scleroderma is characterized by inflammation and fibrosis, predominantly occurring in the skin and extending to various parts of the body. The pathophysiology of scleroderma is multifaceted, with the current understanding including endothelial damage, inflammatory cell infiltration, and fibroblast activation in its progression. Nonetheless, the mechanism of cellular interactions and the precise spatial distribution of these cellular events within the fibrotic tissues remain elusive, highlighting a critical gap in our comprehensive understanding of scleroderma’s pathogenesis.Methods::In this study, we administered bleomycin intradermally to the dorsal skin of four individual murine models. Subsequently, skin tissues were harvested at predetermined intervals for comprehensive spatial transcriptomic analysis to determine the spatial dynamics influencing scleroderma pathogenesis. To validate the possible results from bioinformatic analysis, further in vitro and in vivo experiments were conducted. Results::Analysis of the spatial transcriptome revealed significant alterations in cell clusters during the progression of scleroderma. Gene Ontology analysis identified disruptions in lipid metabolism as the disease advanced. Pseudotime analysis provided evidence for a phenotypic transition from adipocytes to fibroblasts. In vitro studies demonstrated increased expression of Col1a1 and α-SMA as the disease progressed. These fibroblasts have been identified as key contributors to the increasing inflammation. Co-culturing TGF-β induced adipocytes with RAW264.7 cells resulted in overexpression of pro-inflammatory cytokines in the RAW264.7 cells. Both in vitro and in vivo experiments confirmed adipocyte loss and fibroblast formation, with transformed fibroblasts showing pronounced pro-inflammatory characteristics, highlighting their crucial role in the disease mechanism. Conclusions::Our study showed the spatial distribution and dynamic alterations of various cell types during scleroderma progression. Crucially, we identified the transformation of adipocytes into fibroblasts as a key factor promoting disease advancement. These emergent fibroblasts intensify inflammation, indicating that research on these cell clusters could reveal key scleroderma mechanisms and guide future therapies.

Objective:To investigate the factors contributing to in-hospital mortality among elderly patients aged 80 and above with gastrointestinal bleeding(GIB).Additionally, it seeks to assess the predictive ability of the electronic frailty index(eFI)in determining the risk of in-hospital mortality in GIB patients.Methods:A retrospective analysis was performed among 624 patients aged 80 and above with GIB who were admitted to Beijing Hospital between July 2013 and September 2019.The patients were categorized into two groups based on their discharge outcomes: those who survived and those who did not.The eFI was developed using a cumulative deficit model utilizing data from the hospital's electronic medical records.The study examined the clinical features and risk factors associated with in-hospital mortality among these elderly patients.The effectiveness of eFI in predicting in-hospital mortality in elderly patients with gastrointestinal bleeding was evaluated by calculating the area under the curve(AUC)of the receiver operating characteristic(ROC)curve.Results:Among a total of 624 patients aged between 80 and 102 years, the average age was(83.0±6.4)years, with 339 being male.A majority of the patients, 581 cases(93.1%), had an eFI ≥ 0.15.A comparison between the survival group(380 cases)and the death group(244 cases)revealed that the latter had higher eFI values(0.39±0.09 vs.0.29±0.11, t=-11.452, P<0.001), along with higher rates of heart failure, chronic kidney disease, and malignant tumors, as well as lower body mass index, hemoglobin, albumin, and total cholesterol levels, and higher alanine aminotransferase and D-dimer levels(all P<0.05).Logistic regression analysis indicated that eFI( OR=2.322, 95% CI: 1.840-2.929, P<0.001), malignant tumor( OR=1.833, 95% CI: 1.141-2.860, P<0.001), and albumin<35 g/L( OR=1.826, 95% CI: 1.200-2.777, P<0.001)were independent risk factors for in-hospital death in elderly patients aged 80 and over with gastrointestinal bleeding.With every 0.1 increase in eFI, the risk of in-hospital death rose by 1.322 times.The AUC of eFI for predicting in-hospital mortality was 0.751(95% CI: 0.713-0.789, P<0.001).An eFI of ≥0.33 demonstrated a sensitivity of 77.9% and a specificity of 60.3% in predicting in-hospital mortality in elderly patients aged 80 and over with GIB. Conclusions:The eFI serves as an important independent risk factor for in-hospital mortality among patients aged 80 and above who experience GIB.It can effectively assess the prognosis of elderly individuals facing GIB.

The density and composition of lymphocytes infiltrating colon tumors serve as predictive factors for the clinical outcome of colon cancer.Our previous studies highlighted the potent anti-cancer properties of the principal compounds found in Garcinia yunnanensis(YTE-17),attributing these effects to the regu-lation of multiple signaling pathways.However,knowledge regarding the mechanism and effect of YTE-17 in the prevention of colorectal cancer is limited.In this study,we conducted isobaric tags for relative and absolute quantification(iTRAQ)analysis on intestinal epithelial cells(IECs)exposed YTE-17,both in vitro and in vivo,revealing a significant inhibition of the Wnt family member 5a(Wnt5a)/c-Jun N-terminal kinase(JNK)signaling pathway.Subsequently,we elucidated the influence and mechanism of YTE-17 on the tumor microenvironment(TME),specifically focusing on macrophage-mediated T helper 17(Th17)cell induction in a colitis-associated cancer(CAC)model with Wnt5a deletion.Additionally,we performed the single-cell RNA sequencing(scRNA-seq)on the colonic tissue from the Wnt5a-deleted CAC model to characterize the composition,lineage,and functional status of immune mesenchymal cells during different stages of colorectal cancer(CRC)progression.Remarkably,our findings demon-strate a significant reduction in M2 macrophage polarization and Th17 cell phenotype upon treatment with YTE-17,leading to the restoration of regulatory T(Treg)/Th17 cell balance in azoxymethane(AOM)/dextran sodium sulfate(DSS)model.Furthermore,we also confirmed that YTE-17 effectively inhibited the glycolysis of Th17 cells in both direct and indirect co-culture systems with M2 macrophages.Notably,our study shed light on potential mechanisms linking the non-canonical Wnt5a/JNK signaling pathway and well-established canonical β-catenin oncogenic pathway in vivo.Specifically,we proposed that Wnt5a/JNK signaling activity in IECs promotes the development of cancer stem cells with β-catenin activity within the TME,involving macrophages and T cells.In summary,our study undergoes the po-tential of YTE-17 as a preventive strategy against CRC development by addressing the imbalance with the immune microenvironment,thereby mitigating the risk of malignancies.

Aim To investigate the effect of alfentanil on myocardial ischemia-reperfusion injury(MIRI)in rats and its regulatory mechanism on the sphingosine kinase 1(SphK1)/sphingosine-1-phosphate(S1P)signaling pathway dur-ing this process.Methods SPF grade SD male rats were randomly divided into sham surgery group,model group,positive drug group(compound salvia miltiorrhiza group),low dose alfentanil group,high dose alfentanil group,and high alfentanil+SphK1 agonist group(alfentanil+PMA group),with 20 rats in each group.Except the sham operation group,the MIRI model was reproduced by ligating the left anterior descending coronary artery and reperfusion.The activities of serum lactate dehydrogenase(LDH),creatine kinase(CK)and aspartate aminotransferase(AST)were detected by auto-matic biochemical analyzer;TTC was applied to detect the size of myocardial infarction in rats;HE staining was applied to observe the morphological characteristics of rat myocardial tissue;TUNEL staining was applied to detect myocardial cell ap-optosis in rats;ELISA was applied to detect the levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),inter-leukin-1β(IL-1β),and S1P;kits were applied to detect content of malondialdehyde(MDA)and activity of superoxide dismutase(SOD)in myocardial tissue;Western blot was applied to detect the expression level of SphK1 protein in myocar-dial tissue.Results Compared with the sham surgery group,the pathological damage to the myocardial tissue of rats was severe in the model group,the activities of serum central muscle injury markers LDH,CK,and AST,myocardial in-farction area,myocardial cell apoptosis rate,the levels of TNF-α,IL-6,IL-1β,MDA,S1P and the expression of SphK1 protein all increased,the activity of SOD decreased(P＜0.05).Compared with the model group,the myocardial tissue damage of rats was reduced in the positive drug group and the low and high dose alfentanil groups,the activities of serum central muscle injury markers LDH,CK,and AST,myocardial infarction area,myocardial cell apoptosis rate,the levels of TNF-α,IL-6,IL-1β,MDA,S1P and the expression of SphK1 protein all decreased,the activity of SOD increased(P＜0.05).The SphK1 agonist was able to reverse the impact of high-dose alfentanil on the above indicators(P＜0.05).Conclusion Alfentanil has protective effect on MIRI rats,and its mechanism may be related to the inhibition of SphK1/S1P signaling pathway.
