Objectives:To investigate the predictive value of epicardial fat volume(EFV)and atrioventricular groove fat thickness(AVGT)—morphological biomarkers of epicardial adipose tissue—for major adverse cardiovascular events(MACE)in patients with dilated cardiomyopathy(DCM).Methods:This study enrolled 216 DCM patients.EFV and AVGT were obtained from cardiac magnetic resonance imaging(CMR).Patients were divided into event-free group(n=142)and event group(n=74)based on MACE occurrence during follow-up.Receiver operating characteristic(ROC)curve analysis was used to determine optimal cutoff values.Survival differences were assessed using Kaplan-Meier analysis,Cox proportional hazards regression analysis was used to identify independent risk factors,and restricted cubic spline(RCS)models were used to evaluate dose-response relationships.Results:AVGT and EFV were significantly higher in the event group than in event-free group(both P<0.05).ROC analysis identified optimal MACE-predicting cutoffs as follows:AVGT≥7.74 mm(area under the curve[AUC]=0.57)and EFV≥78.6 ml(AUC=0.62).Kaplan-Meier analysis revealed significantly lower MACE-free survival rates in patients with AVGT≥7.74 mm and EFV≥78.6 ml(both P<0.05).Cox regression analysis confirmed that AVGT(HR=2.18,95%CI:1.34-3.54)and EFV(HR=1.81,95%CI:1.11-2.96)were independent MACE risk factors(both P<0.05)in this patient cohort.RCS models demonstrated the significant linear associations between EFV/AVGT and MACE risk(bothoverall P<0.05).Conclusions:EFV and AVGT,the non-invasive imaging biomarkers quantifying and characterizing fat distribution,are independently correlated with elevated MACE risk in DCM patients.These metrics serve as potential prognostic indicators,enriching risk stratification indicators for early identification of high-risk patients and guiding personalized medication strategies.

Objective To investigate the effect of lidocaine on the chemotherapy sensitivity of gastric cancer cells by regulating the Wnt/β-catenin axis. Methods Human gastric cancer cells SGC-7901 in logarithmic growth phase were inoculated into 96-well plates and treated with different concentrations of lidocaine (0, 10, 50, 100, 150, 200 μmol/L) for 24 h. The cell viability at different concentrations was compared. The SGC-7901 cells in logarithmic growth phase were divided into control group, cisplatin group, low concentration lidocaine group (Lido-L group), medium concentration lidocaine group (Lido-M group), high concentration lidocaine group (Lido-H group), high concentration lidocaine + Wnt/β-catenin signal pathway activator SKL2001 group (Lido-H+SKL2001 group). The cell proliferation, invasion, and migration abilities of each group were compared by 5-acetylidene-2'deoxyuracil nucleoside (EdU) cell proliferation detection, Transwell assay, and scratch healing experiment. The apoptosis of each group was detected by TUNEL assay. The expressions of apoptosis, epithelial-mesenchymal transition, and Wnt/β-catenin pathway-related proteins in each group were detected. Results Compared with 0 μmol/L lidocaine, the cell viability of SGC-7901 cells treated with 50, 100, 150, and 200 μmol/L lidocaine was reduced (P < 0.05). Compared with the control group, the EdU positive rate, the number of cell invasion, scratch healing rate, and expressions of vimentin, N-cadherin, B-cell lymphoma-associated protein-2 (Bcl-2), cyclin D1, scattered protein 2 (DVL2), Wnt family member 3a (Wnt3a), β-catenin (β-catenin) were reduced in the cisplatin group, while the cell apoptosis rate was increased, the expressions of E-cadherin, B-cell lymphoma-2-associated X protein (Bax), Cleaved-caspase-3 were increased, and the differences were statistically significant (P < 0.05). Compared with the cisplatin group, the EdU positive rate, the number of cell invasion, scratch healing rate, and expressions of vimentin, N-cadherin, Bcl-2, cyclin Dl, DVL2, Wnt3a, β-catenin were gradually reduced in the Lido-L group, Lido-M group, and Lido-H group, while the cell apoptosis rate, the expressions of E-cadherin, B-cell lymphoma-2-associated X protein (Bax), Cleaved-caspase-3 were increased (P < 0.05). Compared with the Lido-H group, the EdU positive rate, the number of cell invasion, scratch healing rate, and expressions of vimentin, N-cadherin, Bcl-2, cyclin Dl, DVL2, Wnt3a, β-catenin were increased in the Lido-H+SKL2001 group, while the cell apoptosis rate and expressions of E-cadherin, Bax, Cleaved-caspase-3 were reduced, the differences were statistically significant (P < 0.05). Conclusion Lidocaine may enhance the chemotherapy sensitivity of gastric cancer cells by inhibiting the activation of the Wnt/β-catenin axis.

Objective:To investigate the correlation between macular cherry red spot (CS) and severity of neurological manifestations in Chinese children with sialidosis (SD) type I.Methods:A evidence-based medical study. "China", "Sialidosis" and "Sialidoses" were used as Chinese and English search terms. The literature was searched in CNKI, Wanfang and PubMed. The cases were all from China and matched the diagnostic criteria. According to the presence or absence of CS in the fundus, the SD children were divided into a group with CS (+) and a group without CS (-), and the correlation between the occurrence of ocular CS and neurological manifestations was compared with meta-analysis by RevMan 5.3 software.Results:Sixty-eight studies were initially retrieved according to the search strategy, and 17 studies were finally included, and 5 studies with CS+ and CS- were meta-analyzed. Among the 43 patients, 28 were male and 15 were female, with a median age of 12 years. Visual impairment was observed in 37 cases (90.2%, 37/41, 2 cases not recorded), and CS was present in 24 cases (55.8%, 24/43). The most common neurological manifestation was myoclonus (97.7%, 42/43), followed by cerebellar ataxia (95.1%, 39/41, 2 cases not recorded) and seizures (91.4%, 32/35, 8 cases not recorded). Pathogenic NEU1 gene mutations were detected in 42 cases and one case was undocumented. The incidence of seizure in group CS+ (100%, 20/20) was higher than that in group CS- (80%, 12/15). Meta-analysis showed that there was no statistically significant difference between the incidence of myoclonus or ataxia [relative risk ( RR)=1.13, 95% confidence interval ( CI) 0.79-1.63, P=0.49] and seizure ( RR=1.13, 95% CI 0.84-2.06, P=0.24) among the children in the CS+ and CS- groups. Conclusions:The incidence of ocular CS in Chinese children with type I SD was 55.8%. There was no correlation with neurological manifestations, however the incidence of seizure was significantly higher in patients with CS than in others without CS.

BACKGROUND: Stellate ganglion block has the ability to improve the imbalance of the autonomic nervous system in perimenopausal syndrome. Lumbosacral plexus is an automatic nervous block, and exerts similar effects with stellate ganglion block. OBJECTIVE: To investigate the effect of lumbosacral plexus block on the serum level of hormones and histology of the ovary in rabbits, thus providing a new treatment strategy for perimenopausal syndrome. METHODS: This was a randomized controlled animal experiment, which was finished at the Animal Center of Guiyang Medical Unversity, China. The healthy rabbits were randomly divided into experimental and control groups, and underwent lumbosacral plexus block by injecting 0.5 mg of vitamin B12, 100 mg of lidocaine and 10 mL of normal saline into the psoas compartment, and the same volume of normal saline, respectively. The effect of lumbosacral plexus block on the serum levels of hormones (estradiol, gonadotropin releasing hormone, follicle-stimulating hormone and luteinizing hormone) at rabbit proestrus, estrus and metaestrus were observed, respectively. The pathological changes of the ovary in a complete estrus cycle were observed. The relationship between the treatment time of lumbosacral plexus block and the levels of hormones was investigated after 1, 3 and 6 complete estrus cycles. The experimental followed the national guidelines for the Care and Use of Laboratory Animals, and Consensus author guidelines on animal ethics and welfare by the International Association for Veterinary Editors (IAVE), and prepared in accordance with the Animal Research: Reporting of In Vivo Experiments Guidelines (ARRIVE Guidelines). RESULTS AND CONCLUSION: Lumbosacral plexus block can increase the serum level of estrogen, reduce the serum levels of follicle-stimulating hormone and luteinizing hormone, and regulate the hypothalamic-pituitary-ovary axis function. Presumably, it may be used as a treatment method or adjuvant therapy of perimenopausal syndrome. Future experiments are needed to explore the effect of lumbosacral plexus block on the serum levels of hormones in a rabbit after oophorectomy to determine whether it exhibits the same effect on ovarian failure.
