ObjectiveTo combine metabolomics, proteomics, and transcriptomics to analyze the biological characteristics of damp-heat toxin accumulation syndrome and damp-heat accumulation syndrome in acute gout. MethodsBlood samples were collected from 15 patients with damp-heat toxin accumulation syndrome and 15 patients with damp-heat accumulation syndrome in acute gout in clinical practice. Metabolomics technology was applied to detect serum metabolites, and an orthogonal partial sample least squares discriminant analysis model was constructed to screen for metabolites with significant intergroup changes, and enrichment pathway analysis and receiver operating characteristic (ROC) curve analysis were performed. Astral data independence acquisition (DIA) was used to detect serum proteins, perform principal component analysis and screen differential proteins, demonstrate differential ploidy by radargram, apply subcellular localisation to analyse protein sources, and finally apply weighted gene co-expression network analysis (WGCNA) to find key proteins. Transcriptome sequencing technology was also applied to detect whole blood mRNA, screen differential genes and perform WGCNA, and construct machine learning models to screen key genes. ResultsMetabolome differential analysis revealed 62 differential metabolites in positive ion mode and 26 in negative ion mode. These differential metabolites were mainly enriched in the mTOR signaling pathway and FoxO signaling pathway, with trans-3,5-dimethoxy-4-hydroxycinnamaldehyde, guanabenz, 4-aminophenyl-1-thio-beta-d-galactopyranoside showing the highest diagnostic efficacy. The proteome differential analysis found that 55 proteins up-regulated and 20 proteins down-regulated in the samples of damp-heat toxin accumulation syndrome. Notably, myelin basic protein (MBP), transferrin (TF), DKFZp686N02209, and apolipoprotein B (APOB) showed the most significant differences in expression. Differential proteins were mainly enriched in pathways related to fat digestion and absorption, lipid and atherosclerosis, and cholesterol metabolism. WGCNA showed the highest correlation between damp-heat toxin accumulation syndrome and the brown module, with proteins in this module primarily enriched in the hypoxia-inducible factor 1 (HIF-1) signaling pathway and lipid and atherosclerosis. Transcriptomic differential analysis identified 252 differentially expressed genes, with WGCNA indicating the highest correlation between damp-heat toxin accumulation syndrome and the midnight blue module. The random forest (RF) model was identified as the optimal machine learning model, predicting apolipoprotein B receptor (APOBR), far upstream element-binding protein 2 (KHSRP), POU domain class 2 transcription factor 2 (POU2F2), EH domain-containing protein 1 (EHD1), and family with sequence similarity 110A (FAM110A) as key genes. Integrated multi-omics analysis suggested that damp-heat toxin accumulation syndrome in the acute phase of gout is closely associated with lipid metabolism, particularly APOB. ConclusionCompared to damp-heat accumulation syndrome in the acute phase of gout, damp-heat toxin accumulation syndrome is more closely associated with lipid metabolism, particularly APOB, and lipid metabolism disorders contribute to the development of damp-heat toxin accumulation syndrome in patients with acute gout.

OBJECTIVE To systematically evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with anti-angiogenic drugs for the treatment of unresectable primary liver cancer (PLC). METHODS Retrieved from Chinese and English databases such as CNKI, the Cochrane Library, Google, and Baidu Academic, randomized controlled trial (RCT) about TACE combined with anti-angiogenic drugs for the treatment of unresectable PLC were collected from the inception to May 27, 2024. After screening the literature, extracting data, and evaluating the quality of the literature, network meta-analysis was performed using R 4.2.2 and Stata 17.0. RESULTS A total of 44 RCT were included, involving 5 607 patients and 8 interventions. The network meta-analysis results showed that for prolonging median overall survival (mOS) and median progression- free survival (mPFS), TACE+apatinib had the best efficacy, with TACE+apatinib and TACE+sorafenib ranking as the top two. For improving objective response rate (ORR) and disease control rate (DCR), TACE+donafenib had the best efficacy, with TACE+ donafenib and TACE+ lenvatinib ranking as the top two. In terms of safety, TACE+donafenib was the best, with TACE+donafenib and TACE+apatinib ranking as the top two. CONCLUSIONS TACE+apatinib and TACE+donafenib have good efficacy for patients with unresectable PLC, and TACE+donafenib has the best safety profile.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Objective:
: Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) are challenging lesions with high morbidity and mortality rates. Although research on BBAs is well documented in different populations, the study of BBAs in the Tibetan population is extremely rare. This study aimed to evaluate the characteristics of BBAs and analyze the treatment modalities and long-term outcomes in the Tibetan population in comparison with the Han population.
Methods:
: The characteristics of patients with BBAs of the ICA from January 2009 to January 2021 at our institution were reviewed. The features of aneurysms, treatment modalities, complications, and follow-up outcomes were retrospectively analyzed.
Results:
: A total of 130 patients (41 Tibetan and 89 Han patients) with BBAs of the ICA who underwent treatment were enrolled. Compared with the Han group, the Tibetan group significantly demonstrated a high ratio of BBAs among ICAs (8.6%, 41/477 vs. 1.6%, 89/5563; p<0.05), a high ratio of vasospasm (34.1%, 14/41 vs. 6.7%, 6/89; p=0.001), a high risk of ischemic events (43.9%, 18/41 vs. 22.5%, 20/89; p<0.05), and a low ratio of good outcomes (modified Rankin scale, 0–2) at the 1-year follow-up (51.2%, 21/41 vs. 74.2%, 66/89; p<0.05). The multivariate regression model showed that ischemic events significantly contributed to the prediction of outcomes at 1 year. Further analysis revealed that microsurgery and vasospasm were associated with ischemic events.
Conclusion
: In comparison with Han patients, the Tibetan population had a high ratio of BBA occurrence, a high incidence of ischemic events, and a high ratio of poor outcomes. The endovascular approach showed more benefits in BBA patients.

Objective:To investigate the pathogenic genes, clinical features and treatment as well as follow-up of children with congenital long QT syndrome (LQTS).Methods:The clinical data, genetic test results and follow-up data of 16 congenital LQTS children with syncope as the first manifestation admitted to the Department of Cardiology, Beijing Children′s Hospital Affiliated to Capital Medical University from August 2016 to March 2023 were collected and retrospectively analyzed.Results:Among the 16 LQTS patients, the age of first syncope onset was 1.3-13.3 (7.37±3.41) years, and the interval between first syncope onset and clinical diagnosis was 0-48 (14.8±16.2) months.A total of 13 (81.3%) patients had triggers of syncope, of which nine were exercise-induced and four were emotional induced.Genetic testing was performed in 13 patients with LQTS, of which 12 (92.3%) were found to have pathogenic or suspected pathogenic mutations from KCNQ1, KCNH2, and SCN5A gene.The corrected QT interval of 16 patients was (550.0±50.2) ms, all cases≥460 ms.Schwartz scored 6.0 (5.0, 6.0) points, all cases≥4 points.All patients were initially treated with metoprolol or propranolol, of which 14 patients were followed up to date, three patients had recurrent syncope, and five patients stopped taking the medicines by themselves.One patient with high-dose metoprolol (LQT2) was treated with mexiletine after recurrent episodes.One patient who was intolerant to high-dose propranolol underwent left cardiac sympathectomy and was followed up after surgery without syncope episodes.None of the patients underwent implantable cardioverter defibrillator implantation. Conclusion:Children with LQTS and syncope symptoms have high positive rate of genetic tests.The genetic results could assist typing of patients with LQTS and guide treatment.Routine electrocardiogram screening in children with syncope may diagnose LQTS earlier and reduce misdiagnosis and missed diagnosis.β-blockers are the cornerstone of treatment for patients with LQTS.Strengthening follow-up management and improving patients′ treatment compliance is conducive to further improving the treatment response rate of patients.

ObjectiveTo characterize the prevalence and epidemic situation of imported malaria cases in Songjiang District of Shanghai from 2013 to 2022, and to provide evidence for malaria prevention and control. MethodsRelated data were collected and analyzed, including malaria cases, blood testing of febrile patients, and mosquito surveillance in Songjiang from 2013 to 2022. ResultsA total of 13 002 febrile patients in Songjiang were tested for plasmodium parasites from 2013 to 2022, among which 18 malaria cases were confirmed, including 17 cases of falciparum malaria and 1 case of ovale malaria. Moreover, a total of 36 malaria cases were notified in Songjiang through the National Notifiable Disease Reporting System from 2013 to 2022, including cases reported from Songjiang District and other districts or provinces with physical addresses in Songjiang. Of them, there were 31 cases of falciparum malaria, 2 cases of vivax malaria, 2 cases of ovale malaria and 1 case of quartan malaria. The gender ratio of male to female cases was 17∶1, and the majority was young and middle aged. In addition, 35 cases were imported from Africa and 1 case from southeast Asia; 34 cases were migrant workers, and 2 cases were travellers abroad; 17 cases were found and reported in Songjiang, 15 cases were reported from other districts of Shanghai, and 4 cases were reported from other provinces; 27 cases were treated in Shanghai, 3 cases were treated in other provinces and 6 cases were treated with self-provided antimalarial drugs. Mosquito surveillance in Songjiang showed that density of Anopheles sinensis was extremely low. ConclusionNo indigenous malaria case has been notified in Songjiang since 2008. Malaria surveillance on migrant workers remains the focus of malaria prevention and control. Furthermore, achievement of malaria elimination in Songjiang should be continually enhanced to avoid potential further transmission of imported malaria.

【Objective】 To investigate the effect of total flavone of oldenlandia diffusa(FOD) on the stemness, proliferation and apoptosis of breast cancer(BC) stem cells sorted from MDA-MB-231. 【Methods】 Human BC cell lines MDA-MB-231 was cultured in vitro; MDA-MB-231 was stimulated by different concentrations(0 μg/mL, 100 μg/mL, 200 μg/mL and 400 μg/mL) of FOD for different time (24 h, 48 h and 72 h). CCK8 and plate cell cloning assay were used to detect the effect of FOD on MDA-MB-231 proliferation; CD44+/CD24-MDA-MB-231 cell line were tested by flow cytometry and stem cell markers such as Nanog, Oct4 and Sox2 were tested by Western blotting; Annexin V-PE/7-AAD was used to detect the effect of FOD on MDA-MB-231 apoptosis and Bcl2, cleaved-caspase3 and Bax were tested by Western blotting. 【Results】 Cell proliferation of MDA-MB-231 was significantly inhibited by FOD, with the significant suppression at concentrations of 400 μg/mL for 72 h compared with negative control group(P<0.05). The apoptosis rate was significantly upregulated than the negative control group (P<0.05). The protein expression of Bcl2 decreased while Bax and cleaved-caspae3 increased, and stemness markers such as Nanog, Sox2 and Oct4 decreased in FOD-treated cells. Moverover, Akt-GSK3β-β-catenin axis was inhibited in FOD-treated cells. 【Conclusion】 FOD could significantly inhibit the stemness and proliferation and promote the apoptosis of MDA-MB-231.
