OBJECTIVES: Psoriasis is associated with lipid metabolism disorders, but the underlying mechanisms remain unclear. This study aims to investigate the role of trimethylamine N-oxide (TMAO) in lipid metabolism dysregulation in psoriasis. METHODS: An imiquimod (IMQ)-induced psoriasis-like mouse model was used to assess lipid metabolism parameters, TMAO levels, and liver flavin monooxygenase 3 (FMO3) mRNA expression. Blood samples from healthy individuals and psoriatic patients were collected to measure serum TMAO levels and lipid profiles. To clarify the role of TMAO in the lipid metabolism disorder of mice with psoriasis model, exogenous TMAO, choline, or 3,3-dimethyl-1-butanol (DMB) were administered via intraperitoneal injections or diet in IMQ-treated mice. Liver tissues from the mouse models were subjected to RNA sequencing to identify TMAO-regulated signaling pathways. RESULTS: IMQ-induced psoriatic mice exhibited abnormal glucose, insulin, and lipid levels. IMQ treatment also downregulated the hepatic mRNA expression of glucose transporter 2 (Glut2) and silence information regulator 1 (Sirt1), while upregulating glucose transporter 4 (Glut4) and peroxisome proliferator-activated receptor gamma (PPARγ). Elevated serum TMAO levels were observed in both psoriatic patients and IMQ-treated mice. Additionally, liver FMO3 mRNA expression was increased in the psoriatic mouse model. In patients, TMAO levels positively correlated with Psoriasis Area and Severity Index (PASI) scores, serum triglyceride (TG), and total cholesterol (TC) levels. The intraperitoneal injection of TMAO exacerbated lipid dysregulation in IMQ-treated mice. A choline-rich diet further aggravated lipid abnormalities and liver injury in psoriatic mice, whereas DMB treatment alleviated these effects. RNA-Seq analysis demonstrated that TMAO upregulated hepatic microRNA-122 (miR-122), which may suppress the expression of gremlin 2 (GREM2), thus contributing to lipid metabolism disorder. CONCLUSIONS TMAO may promote lipid metabolism dysregulation in psoriasis by modulating the hepatic miR-122/GREM2 pathway.

Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

ObjectiveTo investigate the objective characteristics of tongue manifestations in patients with coronary heart disease （CHD）. MethodsA total of 315 participants with CHD were recruited in the CHD group， and 211 healthy participants who underwent physical examination were recruited as the healthy control group. In addition， according to the common comorbidities （primary hypertension， carotid atherosclerosis， type 2 diabetes mellitus， fatty liver， hyperlipidaemia， heart failure， and cerebral infarction） in 315 participants with CHD， each comorbidity was classified into a group of comorbidities with that disease and a group of non-comorbidities. Tongue images were captured using a TFDA-1 tongue diagnostic instrument to characterise the tongue body （TB） and tongue coating （TC）， comparing the RGB， HIS， and Lab colour spaces in the chromaticity index （R， red； G， green； B， blue； H， hue； I， intensity； S， saturation； L， lightness； a， red-green axis； b， yellow-blue axis）， the tongue coating thickness index （per-All）， contrast （CON）， angular second moment （ASM）， entropy （ENT）， and mean （MEAN） in texture metrics. ResultsCompared with the healthy control group， the characteristic indexes of tongue body in CHD group showed lower TB-R， TB-G， TB-B， TB-I， TB-L and higher TB-H， TB-b； and the characteristic indexes of tongue coating in CHD group showed lower TC-R， TC-B and higher TC-CON， TC-MEAN， TC-H， TC-b （P＜0.05 or P＜0.01）. Compared with non-combined primary hypertension group， CHD combined primary hypertension group showed higher per-All， TB-G， TB-L， and lower TB-a， TC-a （P＜0.05）； compared with the non-combined carotid atherosclerosis group， CHD combined carotid atherosclerosis group showed higher TB-CON， TB-ENT， TB-MEAN， and lower TB-ASM （P＜0.05 or P＜0.01）； compared with the non-combined type 2 diabetes mellitus group， CHD combined type 2 diabetes mellitus group showed lower per-All and higher TB-H （P＜0.05 or P＜0.01）； compared with the non-combined fatty liver group， CHD combined fatty liver group showed higher TB-CON， TB-MEAN， TB-ENT， and lower TB-ASM and TC-S （P＜0.05 or P＜0.01）； compared with the non-combined hyperlipidaemia group， CHD combined hyperlipidaemia group showed lower TB-S and TB-a （P＜0.05）； compared with non-combined heart failure group， CHD combined heart failure group showed lower TB-R， TB-G， TB-I， TB-L， and higher TB-a （P＜0.05 or P＜0.01）； compared with non-combined cerebral infarction group， CHD combined cerebral infarction group showed higher TC-CON， TC-ENT， TC-MEAN， and lower TC-ASM （P＜0.05 or P＜0.01）. ConclusionCompared to healthy individuals， patients with CHD tend to have darker tongue colours and rougher TC textures. Compared with non-comorbidity participants， those with primary hypertension tended to be lighter tongue colour and thicker tongue coating， those with carotid atherosclerosis had paler tongue body， those with type 2 diabetes mellitus had thinner tongue coating， those with fatty liver disease had paler tongue body and whiter tongue colour， those with hyperlipidaemia and heart failure had paler tongue colour， and those with cerebral infarction had rougher tongue texture.

Objective The aim of this study was to investigate the risk factors for delayed postoperative ileus(PPOI)in colon cancer patients undergoing complete laparoscopic right hemicolectomy combined with intraperitoneal thermal perfusion chemotherapy(HIPEC),and establish a risk prediction model.Methods A retrospective analysis was performed on the case data of 68 colon canc-er patients who underwent complete laparoscopic right hemicolectomy combined with HIPEC at the Department of General Surgery,the First Medical Center of PLA General Hospital from January 2018 to January 2021.The incidence of PPOI was statistically analyzed,and its risk factors were analyzed.A nomogram of risk prediction model was constructed and the effectiveness was verified.Results Among the 83 patients,26 cases(31.3％)developed PPOI.Multivariate logistic regression analysis showed that diabetes(OR=14.820,95％CI:2.819-77.918),previous abdominal surgery(OR=6.514,95％CI:1.433-29.604),preoperative Hb＜9 g/L(OR=5.338,95％CI:1.197-23.809),intraoperative hemorrhage more than 200 mL(OR=4.869,95％CI:1.213-19.544),and not close the mesangial hiatal(OR=5.462,95％CI:1.408-21.186)were the risk factors for PPOI.Based on the results of multiva-riate analysis,a risk prediction model for ROC curve and PPOI nomogram was constructed.The internal validation consistency index(C-index)was 0.85(95％CI:0.735-0.957).Conclusion The risk factors for PPOI after complete laparoscopic right hemicolec-tomy combined with HIPEC are diabetes,previous abdominal surgery,preoperative Hb＜9 g/L,intraoperative hemorrhage more than 200 mL,and failure to close the mesangial hiatal.The constructed nomogram of risk prediction model for PPOI after complete laparo-scopic right hemicolectomy has a good evaluating effect and clinical application value.

Objective To compare the clinical effects of intravascular ultrasound (IVUS) and blood flow reserve fraction (FFR) in guiding the treatment of critical disease of coronary artery.Methods Forty nine patients with coronary artery disease who underwent coronary angiography were divided into IVUS group (n=43) and FFR group (n=51).In IVUS group,such as MLA ＜4 mm2 or coronary artery stenosis was insufficient,but IVUS showed unstable plaque,and we went the PCI treatment;in the FFR group,FFR＜0.75 was regarded as coronary stenting sign.The patients were followed up for 6 months.The incidence of cardiovascular adverse events was compared between the two groups.Results (1)There was no significant difference in general information and coronary angiography between the two groups (P＞ 0.05).(2)The proportion of interventional therapy in IVUS group was higher than that in FFR group (P＜0.01).(3)The incidence of adverse events between the two groups was not statistically significant (P＞0.05).Conclusion IVUS and FFR examination can be used to guide the interventional treatment of critical disease of coronary artery.However,the accuracy of IVUS can not replace the status of blood flow reserve.
