To evaluate the accuracy of contrast-enhanced ultrasound diagnostic reports for pancreatic lesions. In this retrospective study, we included patients who underwent contrast-enhanced ultrasound examination of pancreatic lesions at Peking Union Medical College Hospital from January 2017 to December 2022 and received a confirmed pathological diagnosis. Using pathological diagnosis as the gold standard, the study evaluated the accuracy of contrast-enhanced diagnostic ultrasound. It also analyzed the misdiagnosis of contrast-enhanced ultrasound in diagnosing various pathological types of pancreatic lesions. Of the 859 patients who met inclusion and exclusion criteria, 489 were male(56.9%) and 370 were female(43.1%).Their age ranged from 16 to 85 years, with a median age of 60(53, 66) years. Except for 47 pancreatic space-occupying lesions that were difficult to categorize as either benign or malignant, a total of 812 cases were included in the diagnostic efficacy analysis of benign and malignant lesions. The results suggested that the diagnostic sensitivity and specificity of contrast-enhanced ultrasound for pancreatic malignant lesions were 98.3%(95% CI: 97.1%-99.1%) and 79.0%(95% CI: 70.1%-86.4%), AUC was 0.887(95% CI: 0.863-0.908), positive and negative predictive value were 96.9%(95% CI: 95.6%-97.9%) and 87.4%(95% CI: 79.6%-92.4%), positive and negative likelihood ratio were 4.69(95% CI: 3.24-6.80) and 0.02(95% CI: 0.01-0.04). The diagnostic accuracy rate of contrast-enhanced ultrasound for diagnosing benign and malignant pancreatic lesions was 95.8%. Of the 859 lesions examined, 48 cases were misdiagnosed by contrast-enhanced ultrasound, with a misdiagnosis rate of 5.6%(48/859), including 7 cases(0.8%) of undetermined diagnosis, while the diagnostic accuracy of pancreatic ductal adenocarcinoma was as high as 98.8%. No complications occurred in any of the patients. Contrast-enhanced ultrasound is a safe and effective imaging method for evaluating microvascular perfusion in various pancreatic lesions. It has significant clinical value in diagnosing both benign and malignant pancreatic lesions, particularly in diagnosing pancreatic ductal adenocarcinoma.

Objective To explore the expression and diagnostic value of circulating microRNA(miR)-126-3p in non-small cell lung cancer(NSCLC).Methods Multi-centred miR chips and sequencing data were col-lected to investigate the differential expression of circulating miR-126-3p in NSCLC.In order to evaluate the comprehensive expression level of circulating miR-126-3p in the cycle,the standardized mean difference(SMD)and summary receiver operating characteristic(sROC)curve were calculated,and the area under curve(AUC)of sROC curve was analyzed.Sensitivity,specificity,positive negative likelihood ratio were ex-plored,and the expression of circulating miR-126-3p was further comprehensively analyzed in combination with tissue.By using miRDB,starBase v2.0,and TargetScan 7.1,combined with up-regulated differentially expressed genes in NSCLC,potential target genes of circulating miR-126-3p were screened using complemen-tary sequence method.Results Based on six circulating miR datasets,the expression level of circulating miR-126-3p was higher than that of the control group,and the difference was statistically significant(P<0.05).The receiver operating characteristic curves showed that circulating miR-126-3p had strong diagnostic efficacy(AUC>0.5),and the comprehensive expression of circulating miR-126-3p was lower in 199 cases of NSCLC group than in the control group(SMD=-1.46).The sROC curve showed that circulating miR-126-3p distin-guished the NSCLC group from the control group with high accuracy(AUC=0.91),Egger's test showed no publication bias(P>0.05),with sensitivity and specificity 0.80,and positive likelihood ratio and negative likelihood ratio were 5.37 and 0.18,respectively.In addition,a comprehensive analysis of the circulation and tissue of 1 320 NSCLC samples from 26 datasets showed that circulating miR-126-3p expression was lower in NSCLC group than in the control group(SMD=-2.07).The sROC curve showed that low-expression circu-lating miR-126-3p had high accuracy in distinguishing between the NSCLC group and the control group(AUC=0.97).In addition,potential target genes ADAM9 and SLC7A5 were screened for circulating miR-126-3p,and their expression in NSCLC group was higher than that in the control group.Conclusion Low ex-pression of circulating miR-126-3p in the circulation may be an important biomarker for high-precision screen-ing of NSCLC.

In order to understand the difference and expression of genes in CEK cells before and af-ter baicalin interferes with IBV,further reveal and analyze the mechanism of baicalin interfering IBV replication in CEK cells in vitro.After IBV infected CEK cells for 2 h,9.75 mg/L baicalin liq-uid was added to interfere with CEK cells,which was recorded as the baicalin(H-IBV)group,and three replicate wells were set in the control group and the IBV(IBV)infection group.After 36 h culture,cell samples were collected and subject to transcriptome for sequencing.The results showed that there were 102 differentially expressed genes in H-IBV group compared with IBV in-fection group,among which 48 genes weresignificantly up-regulated and 54 genes were significantly down-regulated.Through functional annotation in GO and KEGG databases,it was found that dif-ferentially expressed genes were mainly annotated in biological processes such as cellular proces-ses,biological regulation,metabolism,and secondary pathways such as viral infectious diseases,signal transduction and interaction.Retinol metabolism pathway,phospholipid transfer to mem-brane,IL-27 mediated signaling pathway,MDA5/RIG-I and Toll-like receptor signaling pathway were significantly enriched in CEK cells,and the production of type Ⅰ interferon and interferon al-pha and the process of antiviral infection were also positively regulated.There were more differen-tial genes enriched in nucleic acid catalysis,immune system,and reaction,and interbiological reac-tion.Through the STRING network interaction map,it was found that most immune-related genes could form a 36-node interaction network centered on IRF7,TLR3 and STAT1.Therefore,com-pared with IBV group,the differentially expressed genes after baicalin treatment were mainly an-notated and enriched in the biological process,and the immune system and response were en-hanced,mainly through the positive regulation of IRF7 in the MDA5/RIG-I receptor signaling pathway and the inhibition of TLR3 signal transduction in the Toll-like receptor signaling path-way.Positive regulation of IL-27 mediated pathway and regulation of JAK-STAT signaling path-way were supplemented by activation of the expression of IRF7,TLR3,STAT1 and other related genes,and interaction with corresponding downstream proteins to promote the expression of IFN-α and regulatory cytokines,coupled with negative regulation of viral(defense)response and viral processes.Thus,baicalin interferes with IBV replication in CEK cells.

Evaluating the consistency of herb injectable formulations could improve their product quality and clinical safety, particularly concerning the composition and content levels of trace ingredients. Panax notoginseng Saponins Injection (PNSI), widely used in China for treating acute cardiovascular diseases, contains low-abundance (10%-25%) and trace saponins in addition to its five main constituents (notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, and ginsenoside Rd). This study aimed to establish a robust analytical method and assess the variability in trace saponin levels within PNSI from different vendors and formulation types. To achieve this, a liquid chromatography-triple quadrupole mass spectrometry (LC-MS/MS) method employing multiple ions monitoring (MIM) was developed. A "post-column valve switching" strategy was implemented to eliminate highly abundant peaks (NR1, Rg1, and Re) at 26 min. A total of 51 saponins in PNSI were quantified or relatively quantified using 18 saponin standards, with digoxin as the internal standard. This study evaluated 119 batches of PNSI from seven vendors, revealing significant variability in trace saponin levels among different vendors and formulation types. These findings highlight the importance of consistent content in low-abundance and trace saponins to ensure product control and clinical safety. Standardization of these ingredients is crucial for maintaining the quality and effectiveness of PNSI in treating acute cardiovascular diseases.

Objective:To explore the clinical and electro-physiological characteristics of reflex epilepsy induced by thinking activities.Methods:Five patients of reflex epilepsy induced by thinking activities during electroencephalogram (EEG) monitoring in the EEG Monitoring Center, Department of Neurology, Xijing Hospital,the Air Force Military Medical University from January 2017 to September 2019 were studied and followed up.Results:All the 5 patients are male, aged 14 to 33 years, with the disease course of 3 to 9 years and the follow-up of 1 to 4 years. The myoclonic jerks, spasms seizure and generalized tonic and clonic seizure occured to the 5 patients. The EEG background of low amplitude alpha rhythm was recorded in the 5 patiens. The ictal-EEG of 2 cases showed the spike wave or spike slow complex waves in the central, parietal area, and the ictal-EEG of 1 case showed the generalized spike-wave discharge. There were no seizures occuring to the 2 cases during video-electroencephalography monitoring. There were no abnormalities in cranial magnetic resonance imaging. The arterial spin labeling of 2 cases suggested that the right cerebral hemisphere cerebral blood flow was lower than contralateral. Antiseizure drugs (levetiracetam in 4 cases and levetiracetam+magnesium valproate in 1 case) were administered, 4 cases were seizure free and 1 case was uncontrolled.Conclusions:The reflex epilepsy induced by thinking activities is common in young men, and the EEG background with low amplitude alpha rhythm may be the characteristic of the reflex epilepsy induced by thinking activities. The levetiracetam may be the good choice for the reflex epilepsy induced by thinking activities and the prognosis of reflex epilepsy induced by thinking activities is good.

Objective:To explore the association between short-term exposures to fine particulate matter (PM 2.5) on blood lipids in the elderly. Methods:In this panel study, five repeated measurements were performed on 76 people aged 60-69 in Jinan city. Each participant had a PM 2.5 monitor for 72 hours before each health examination, including a questionnaire survey, physical examination, and biological sample collection. Serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were examined, and non-HDL-C concentrations were calculated by subtracting HDL-C from TC. The generalized linear mixed-effects model was used to quantify the association of personal PM 2.5 exposure at different lag with blood lipids and dyslipidemia. Results:The age of 70 participants was (65.0±2.8) years, of which 48.6% (34/70) were males. The BMI of participants was (25.0±2.5) kg/m 2. Their TC, TG, LDL-C, HDL-C, and non-HDL-C concentrations were (5.75±1.32), (1.55±0.53), (3.27±0.94), (1.78±0.52), and (3.97±1.06) mmol/L, respectively. Generalized linear mixed-effects model showed that after adjusting for confounding factors, at lag 72 hours, each 10 μg/m 3 increase in PM 2.5 was associated with the percentage change in TC, LDL-C, HDL-C and non-HDL-C about 1.77% (95% CI: 1.22%-2.32%), 1.90% (95% CI: 1.18%-2.63%), 1.99% (95% CI: 1.37%-2.60%) and 1.74% (95% CI: 1.11%-2.37%), and the OR values (95% CI) of hypercholesterolemia, hypertriglyceridemia and hyperbetalipoproteinemia were 1.11 (1.01-1.22), 1.33 (1.03-1.71) and 1.15 (1.01-1.31), respectively. Conclusion:There is a significant association of short-term PM 2.5 exposure with the concentration of blood lipids and the risk of dyslipidemia in the elderly.
