Background: The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies. Methods: MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function. Results: Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores. Conclusion Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

Objective:To systematically evaluate the clinical outcomes of hemihepatic inflow occlusion(HHO)and total hepatic inflow occlusion(THO)in liver resection surgery.Method:Re-trieve the Cochrane Library,PubMed,EMbase,Ovid,Web of Science,CNKI,and WanFang Data databases,and search for journal articles published from January 1,2000 to January 31,2023,on randomized controlled trials(RCTs)comparing the effects of HHO and THO in liver resection.At the same time,two researchers independently screened literature based on inclusion and exclusion cri-teria,conducted meta-analysis using RevMan 5.4 and State17PM software.Result:Fifteen RCTs were ultimately included,including 624 patients.The meta-analysis results showed that HHO re-duced serum AST(MD=-104.75,95％CI:-134.45-75.06,P＜0.05),ALT(MD=-155.37,95％CI:-182.90-127.85,P＜0.05),and TBIL(MD=-6.28,95％CI:-8.07-4.48,P＜0.05)on postoperative days 1,3,and 7 Compared to THO,the elevation of blood levels and reduction of intraoperative bleeding(MD=-66.21,95％CI:-116.49-15.94,P＜0.05)were superior.THO is superior to HHO in shortening surgical time(MD=13.94,95％CI:4.77-23.12,P＜0.05).There was no significant differ-ence between the two methods in hospital stay,hospital death rate and complication rate(P＞0.05).Conclusion:compared with THO,the application of HHO in hepatectomy has less damage to liver function and less intraoperative bleeding,but the two methods have the similar effect in terms of hospitalization time,hospital mortality rate and complication rate.

Purpose::Shaping and assembling contemporary external fixators rapidly for the severe mandibular fractures remains a challenge, especially in emergency circumstance. We designed a novel external fixator that incorporates universal joints to provide the stabilization for mandibular comminuted fractures. This study aims to confirm the efficacy of this novel external fixator through biomechanical tests in vitro and animal experiments. Methods::In vitro biomechanical tests were conducted using 6 fresh canine with mandibular defect to simulate critical comminuted fractures. Three mandibles were stabilized by the novel external fixator and other mandibles were fixed by 2.5 mm reconstruction plates. All fixed mandibles were subjected to loads of 350 N on the anterior regions of teeth and 550 N on the first molar of the unaffected side. The stability was evaluated based on the maximum displacement and the slope of the load-displacement curve. In animal experiments, 9 beagles with comminuted mandibular fractures were divided into 3 groups, which were treated with the novel external fixation, reconstruction plate, and dental arch bar, respectively. The general observation, the changes in animals’ weight, and the surgical duration were recorded and compared among 3 groups. The CT scans were performed at various intervals of 0 day (immediately after the surgery), 3 days, 7 days, 14 days, 21 days, and 28 days to analyze the displacement of feature points on the canine mandible and situation of fracture healing at 28 days. The statistical significance was assessed by the two-way analysis of variance test followed by the Bonferroni test, enabling multiple comparisons for all tests using GraphPad Prism10.1.0 (GraphPad Inc, USA). Results::The outcomes of the biomechanical tests indicated that no statistically significant differences were found in terms of the maximum displacement ( p = 0.496, 0.079) and the slope of load displacement curves ( p = 0.374, 0.349) under 2 load modes between the external and internal fixation groups. The animal experiment data showed that there were minor displacements of feature points between the external and internal fixation groups without statistic difference, while the arch bar group demonstrated inferior stability. The CT analysis revealed that the best fracture healing happened in the internal fixation group, followed by the external fixation and arch baring at 28 days after fixation. The external fixation group had the shortest fixation duration (25.67 ± 3.79) min compared to internal fixation ((70.67 ± 4.51) min, p < 0.001) and arch baring ((42.00 ± 3.00) min, p = 0.046). Conclusion::The conclusion of this study highlighted the efficacy and reliability of this novel external fixator in managing mandibular fractures rapidly, offering a viable option for the initial stabilization of comminuted mandibular fractures in the setting of emergency rescue.

OBJECTIVE: To explore the effect of thoracic paravertebral anesthesia (TPVB) on prognosis of patients undergoing resection of lung cancer. METHODS: This study was conducted among the patients undergoing surgical resection of primary lung cancer under general anesthesia or TPVB combined with general anesthesia (TPVB+GA) between January, 2017 and May, 2018.The patients were enrolled in TPVB+GA group and GA group (control group) using a propensity score matching (PSM) method at the ratio of 1:2 based on their baseline characteristics.The clinical parameters, 5-year overall survival (OS), progression-free survival (PFS) and intraoperative dosage of opioids were compared between the two groups to assess the impact of TPVB on prognosis of the patients. RESULTS: Forty-seven patients were enrolled in TPVB+GA group and 94 in the control group.Kaplan-Meier survival analysis showed a significantly prolonged PFS in the patients with TPVB+GA (log-rank P=0.034), with an odds ratio (OR) of 0.45(95%CI: 0.33-0.89).Consistently, univariate and multivariate Cox regression analyses identified TPVB as an independent protective prognostic factor for patients with lung cancer resection (P=0.002, OR=0.33, 95%CI: 0.16-0.66).Cox regression analyses indicated that a lower intraoperative dose of remifentanil was significantly correlated with a longer PFS of the patients following lung cancer resection (P=0.017, OR=0.47, 95%CI: 0.25-0.87).Chi-square test confirmed that TPVB, but not general anesthesia, significantly reduced intraoperative dose of remifentanil, indicating a possible synergistic effect of TPVB with opioids to affect the survival of the patients. CONCLUSION TPVB can prolong the survival time and improve the prognosis of the patients undergoing surgical resection of lung cancer.

Background: and Purpose To explore the causal relationships of elements of the exposome with ischemic stroke and its subtypes at the omics level and to provide evidence for stroke prevention. Methods We conducted a Mendelian randomization study between exposure and any ischemic stroke (AIS) and its subtypes (large-artery atherosclerotic disease [LAD], cardioembolic stroke [CE], and small vessel disease [SVD]). The exposure dataset was the UK Biobank involving 361,194 subjects, and the outcome dataset was the MEGASTROKE consortium including 52,000 participants. Results: We found that higher blood pressure (BP) (systolic BP: odds ratio [OR], 1.02; 95% confidence interval [CI], 1.01 to 1.04; diastolic BP: OR, 1.03; 95% CI, 1.01 to 1.05; pulse pressure: OR, 1.03; 95% CI, 1.00 to 1.06), atrial fibrillation (OR, 1.18; 95% CI, 1.13 to 1.25), and diabetes (OR, 1.13; 95% CI, 1.07 to 1.18) were significantly associated with ischemic stroke. Importantly, higher education (OR, 0.69; 95% CI, 0.60 to 0.79) decreased the risk of ischemic stroke. Higher systolic BP (OR, 1.06; 95% CI, 1.02 to 1.10), pulse pressure (OR, 1.08; 95% CI, 1.02 to 1.14), diabetes (OR, 1.28; 95% CI, 1.13 to 1.45), and coronary artery disease (OR, 1.58; 95% CI, 1.25 to 2.00) could cause LAD. Atrial fibrillation could cause CE (OR, 1.90; 95% CI, 1.71 to 2.11). For SVD, higher systolic BP (OR, 1.04; 95% CI, 1.00 to 1.07), diastolic BP (OR, 1.06; 95% CI, 1.01 to 1.12), and diabetes (OR, 1.22; 95% CI, 1.10 to 1.36) were causal factors. Conclusions The study revealed elements of the exposome causally linked to ischemic stroke and its subtypes, including conventional causal risk factors and novel protective factors such as higher education.
