Objective To analyze the correlation between serum miR-140-5p,vascular endothelial growth factor(VEGF)levels and atherosclerosis in patients with rheumatoid arthritis.Methods A total of 80 pa-tients with rheumatoid arthritis admitted to the hospital from January 2022 to September 2023 were regarded as the study group.The study group was separated into the combined group(46 cases)and the non combined group(34 cases)according to whether there was the middle layer thickening and atheromatous plaque in ca-rotid artery ultrasound.Another 40 healthy individuals who came to physical examination center in the hospi-tal for physical examination were selected as the control group.Quantitative real-time PCR(RT-qPCR)and enzyme linked immunosorbent assay(ELISA)were applied to detect miR-140-5p and VEGF levels in the ser-um of subjects.Ultrasound was applied to examine the carotid intima-media thickness in the combined group and the non combined group.Pearson and Spearman were applied to analyze the correlation between clinical data of patients with rheumatoid arthritis,and Logistic regression model was applied to analyze the factors in-fluencing atherosclerosis in rheumatoid arthritis patients.Results There were differences in rheumatoid fac-tor,erythrocyte sedimentation rate(ESR),carotid intima-media thickness,fasting blood glucose(FPG),fast-ing insulin(FINS),insulin resistance index(HOMA-IR),hypersensitive C-reactive protein(hs-CRP),miR-140-5p,and VEGF among the three groups(P＜0.05).The rheumatoid factor,ESR,carotid intima-media thickness,FPG,hs-CRP,and VEGF in the non combined group and combined group were higher than those in the control group,while FINS,HOMA-IR,and miR-140-5p were lower than those in the control group,and the differences were statistically significant(P＜0.05).The rheumatoid factor,carotid intima-media thick-ness,FPG,hs-CRP,VEGF in the combined group were higher than those in the non combined group,and the differences were statistically significant(P＜0.05),while FINS and miR-140-5p were lower than those in the non combined group,and the differences were statistically significant(P＜0.05).The rheumatoid factor,ca-rotid intima-media thickness and hs-CRP in patients with rheumatoid arthritis were negatively correlated with miR-140-5p(P＜0.05)and were positively correlated with VEGF(P＜0.05),and miR-140-5p was negatively correlated with VEGF(P＜0.05).Rheumatoid factor,carotid intima-media thickness,hs-CRP,VEGF were risk factors for atherosclerosis in patients with rheumatoid arthritis,and miR-140-5p was a protective factor(P＜0.05).Conclusion Serum miR-140-5p and VEGF in patients with rheumatoid arthritis are associated with atherosclerosis,miR-140-5p is a protective factor for atherosclerosis,and VEGF is a risk factor.

Objective To evaluate the accuracy,sensitivity,and specificity of isolated-check visual evoked potential(Ic-VEP)in the diagnosis of primary open-angle glaucoma(POAG).Methods The participants were 52 patients(104 eyes)with POAG and 40 healthy controls(80 eyes).All participants were examined using Ic-VEP and Humphrey perimetry to record the signal-to-noise ratio and mean devia-tion.Receiver operating characteristic(ROC)curve analysis was used to characterize the diagnostic performance of Ic-VEP in POAG.Results The sensitivity,specificity,and accuracy of the Ic-VEP qualitative examination were 92.3％,80.0％,and 88.0％,respectively.The area under the curve(AUC)was 0.873(95％CI:0.793-0.953).The sensitivity,specificity,and accuracy of the Ic-VEP quantitative examination were 91.3％,81.3％,and 87.0％,respectively.The AUC was 0.863(95％CI:0.804-0.922).The sensitivity of Ic-VEP in the early stage of POAG(81.3％)was slightly lower than that in the middle and late stages(82.0％),but the difference was not statisti-cally significant(x 2=0.001,P=0.981).The sensitivity of Ic-VEP quantitative examination in the early stage of POAG(88.4％)was slightly lower than that in the middle and late stages(93.4％);however,the difference was not statistically significant(x2=0.037,P=0.847).Conclusion Ic-VEP is an effective diagnostic instrument for middle-late and early stages of POAG.

Objective To explore the effects of dihydromyricetin on the proliferation,apoptosis,and invasion of endometrial cancer(EC)cells and its possible mechanisms.Methods Ishikawa cells in the logarithmic growth phase were taken and divided into the control group,20 μmol/L dihydromyricetin intervention group,40 μmol/L dihydromyricetin intervention group,and 80 μmol/L dihydromyricetin intervention group,which were treated with different final concentrations of dihydromyricetin(0 μmol/L,20 μmol/L,40 μmol/L,80 μmol/L).Then,CCK-8 assay and flow cytometry were used to detect the effects of dihydromyricetin on the cell proliferation and apoptosis.Transwell experiment was used to detect the effect of dihydromyricetin on the cell invasion.qRT-PCR and Western blot were used to detect the effects of dihydromyricetin on the cell expression of miR-21 and PTEN.Results Compared with the control group,the cell proliferation inhibition rate and apoptosis rate in the dihydromyricetin intervention group were significantly increased(P<0.05),and gradually increased with the increase of dihydromyricetin concentration(P<0.05).Compared with the control group,the numbers of migration and invasion cells in the dihydromyricetin intervention group were significantly decreased(P<0.05),and gradually decreased with the increase of dihydromyricetin concentration(P<0.05).Compared with the control group,the cell expression of miR-21 in the dihydromyricetin intervention group was significantly decreased(P<0.05),and gradually decreased with the increase of dihydromyricetin concentration(P<0.05),the expression levels of PTEN mRNA and protein were significantly increased(P<0.05),and gradually increased with the increase of dihydromyricetin concentration(P<0.05).Conclusion Dihydromyricetin can inhibit the growth and metastasis of EC cells,and the inhibitory effect is positively correlated with its concentration.The mechanism may be related to the effect of dihydromyricetin on the miR-21/PTEN signaling pathway of EC cells.

The molecular epidemiological characteristics of 1,4,[5],12:i:-Salmonella in Jiangsu Province were analyzed through whole genome sequencing(WGS).The distribution characteristics of related genes were obtained on the basis of anno-tated drug-resistant genes and plasmid types in the whole genome.Analysis of the molecular epidemiological characteristics of strains with cgMLST revealed possible modes of transmission of quinolone resistance in 1,4,[5],12:i:-Salmonella.Eleven cat-egories of antibiotic resistance genes(ARGs)were annotated among the fluoroquinolone-resistant strains.The detection rate of aminoglycoside ARGs was highest(100％).Twelve quinolone-resistant strains(92.3％)carried the IncHI2/IncHI2A plasmid type.PMQR gene analysis of various strains indicated that the strains from the United States and Europe carried six types of PMQR genes,and the detection rate of qnrB19 was highest.The Jiangsu strains carried three PMQR gene types,and the de-tection rate of aac(6')-Ib-cr was highest(11.84％).Analysis of cgMLST loci from different countries/regions revealed three main epidemic clusters.Some isolates from Jiangsu province might have the same evolutionary origin as some isolates from Eu-rope and the United States,and national/regional differences were observed in the PMQR gene carriage level.

Alcohol abuse is a serious public health problem and biomedical safety problem that can lead to a variety of neuropsychiatric disorders. In recent years, numerous studies have shown that alcohol can induce structural and functional disregulation in the basolateral amygdala (BLA). Alcohol exposure and withdrawal can cause negative emotion such as anxiety and fear, primarily mediated by glutamatergic neurons and inhibitory γ-aminobutyric acid ergic(GABAergic) interneurons in the BLA. Glutamatergic neurons are responsible for excitatory neurotransmitter glutamate release, while γ-aminobutyric acid ergic(GABAergic) interneurons provide feedback inhibition to suppress BLA function and alleviate negative emotions. However, alcohol intake can disrupt the balance of glutamatergic-GABAergic neural network, altering neuron excitability and subsequently leading to the generation of anxiety and fear. Moreover, alcohol also interferes with the corticotropin-releasing factor(CRF) system within the BLA, increasing the release of CRF, further stimulating anxiety-related emotions. Additionally, alcohol affects BLA-related neural circuits, such as BLA →medial prefrontal cortex, BLA →nucleus accumbens, and BLA →bed nucleus of the stria terminali pathways, thereby impacting anxiety-like behaviors.This review discusses the progress of neural signaling and circuits within the BLA in mediating alcohol-induced negative emotions, aiming to further elucidate the neurobiological mechanisms underlying anxiety triggered by alcohol exposure and withdrawal, in order to provide theoretical basis for clinical treatment in the future.

Objective:To analyze the correlation between body fat distribution measured by quantitative CT (QCT) and body mass index in adults receiving physical examination.Methods:It was a cross-sectional study. From January to December 2021, 3 205 adults undergoing physical examination who met the inclusion criteria and underwent chest CT and QCT examination in the health management discipline of Henan Provincial People′s Hospital were selected as the research objects. The general data were collected; and the subcutaneous fat area, visceral fat area, total abdominal fat area, liver fat content, abdominal obesity and fatty liver detection rate were measured by QCT. According to body mass index, the subjects were divided into normal group (18.5-<24.0 kg/m 2, 1 343 cases), overweight group (24.0-<28.0 kg/m 2, 1 427 cases) and obesity group (≥28.0 kg/m 2, 435 cases). One-way analysis of variance and χ2 test were used to compare the differences of QCT indexes among the three groups. Pearson and Spearman correlation analysis were used to evaluate the correlation between QCT indexes and body mass index. Receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic effect of QCT on obesity and fatty liver. Results:Subcutaneous fat area, visceral fat area, total abdominal fat area, liver fat content, abdominal obesity and fatty liver detection rate in obese group were all significantly higher than those in overweight group and normal group [males, (147.60±46.44) vs (104.33±27.68), (73.46±22.65) cm 2; (297.46±54.70) vs (229.40±53.12), (159.57±49.68) cm 2; (445.06±70.24) vs (333.73±62.91), (233.02±61.87) cm 2; 11.30% (7.90%, 15.55%) vs 8.75% (6.50%, 11.70%), 6.60% (4.80%, 8.70%); 100.0% vs 96.0%, 64.0%; 92.9% vs 86.7%, 73.3%; females, (213.96±48.61) vs (155.85±35.31), (107.24±31.01) cm 2; (185.41±43.88) vs (142.48±41.75), (96.56±36.50) cm 2; (399.37±68.07) vs (298.33±56.86), (203.80±57.53) cm 2; 9.80% (6.90%, 13.30%) vs 7.30% (5.05%, 9.80%), 5.40%(3.50%, 7.20%); 96.4% vs 74.8%, 28.9%; 87.3% vs 75.6%, 56.5%], and were all positively correlated with body mass index (males, r/ rs=0.709, 0.738, 0.831, 0.402, 0.464, 0.225; females, r/ rs=0.798, 0.695, 0.841, 0.416, 0.605, 0.276) (all P<0.001). In both male and female subjects, the detection rates of obesity based on QCT were significantly higher than those based on body mass index (male, 86.9% vs 16.6%; female, 49.3% vs 8.9%), and the detection rates of fatty liver based on QCT were significantly higher than those based on ultrasound (male, 83.6% vs 57.1%; female, 65.2% vs 27.6%) (all P<0.001). ROC curve showed that when the visceral fat area of 142 cm 2 was used as the cut-off value for the diagnosis of obesity in male subjects, the sensitivity and specificity was 100% and 15.8%, respectively; and when the cut-off value of liver fat content 5.0% was used to diagnose fatty liver, the sensitivity and specificity was 88.9% and 25.1%, respectively. When the visceral fat area of 115 cm 2 was set as the cut-off value for the diagnosis of obesity in female subjects, the sensitivity and specificity was 96.4% and 55.3%, respectively; when the liver fat content of 5.0% was set as the cut-off value for the diagnosis of fatty liver, the sensitivity and specificity was 83.7% and 43.2%, respectively. Conclusions:The indexes of abdominal fat and liver fat measured by QCT in adults receiving physical examination are all positively correlated with body mass index. The effect of QCT in the diagnosis of obesity and fatty liver are both better than body mass index and ultrasound.

Objective:To analyze the distribution of body fat with quantitative computed tomography (QCT) in people with normal body mass index (BMI).Methods:A cross-sectional study was conducted in the physical examination population who underwent chest CT and QCT examination in the Department of Health Management, Henan Provincial People′s Hospital from January to December in 2021, and 1 395 physical examination subjects who met the inclusion criteria were selected as the research subjects. The subjects were divided into five groups according to their age. The general data of the subjects were collected. The total abdominal fat area (TFA), visceral fat area (VFA), subcutaneous fat area (SFA), total abdominal muscle area (TMA) and muscle fat content (MFC) in the subjects were measured by QCT. One-way analysis of variance, Welch test and Kruskal-Wallis test were used to compare the above QCT measurement indexes between the two genders among different age groups with normal BMI. Pearson correlation analysis was used to analyze the correlation between VFA and sarcopenia indexes. Multivariate linear regression was used to analyze the relationship between VFA and linear correlation variables in the related indicators of sarcopenia.Results:There were significant differences in TFA, VFA, TMA and SMI among different age groups in subjects with normal BMI (all P<0.05). Pearson correlation analysis showed that VFA was negatively correlated with TMA in some age groups (male: 18-39 years group: r=-0.351; 40-49 years group: r=-0.278; 60-69 years group: r=-0.245; female:40-49 years group: r=-0.251; 50-59 years group: r=-0.270;≥70 years group: r=-0.391; all P<0.01); it was negatively correlated with SMI (male: 18-39 years group: r=-0.352; 40-49 years group: r=-0.340; 50-59 years group: r=-0.266; 60-69 years group: r=-0.316; female: 40-49 years group: r=-0.240; 50-59 years group: r=-0.284; all P<0.001); it was positively correlated with MFC (male: 18-39 years group: r=0.342; 40-49 years group: r=0.291; female: 50-59 years group: r=0.133; 60-69 years group: r=0.284; all P<0.05). Multivariate linear regression analysis showed that VFA was independently and negatively correlated with SMI in both men and women after adjusting for age interference factors (male B=-1.881, t=-6.025, P<0.001; female B=-0.603, t=-2.887, P=0.004), and it was independently positively correlated with MFC (male B=1.230, t=4.271, P<0.001;female B=0.893, t=3.836, P<0.001). There was an independent negative correlation between VFA and TMA in male subjects ( B=0.263, t=2.478, P=0.013). Conclusions:VFA is correlated with TMA, SMI and MFC in people with normal BMI. Regardless of gender, SMI has a negative effect on VFA, and MFC has a positive effect on VFA.

Objective:To investigate the perioperative impact of closure of mesenteric fissure in laparoscopic right hemicolectomy.Methods:The prospective randomized controlled trial was conducted. The clinical data of 320 patients who underwent laparoscopic right hemicolectomy in 11 medical centers, including The First Affiliated Hospital of China Medical University et al, from November 2022 to August 2023 were selected. Based on block randomization, patients were alloca-ted into the mesenteric fissure non-closure group and the mesenteric fissure closure group. Observa-tion indicators: (1) grouping of the enrolled patients; (2) intraoperative conditions; (3) postopera-tive conditions. Measurement data with skewed distribution were represented as M( Q1, Q3) and com-parison between groups was conducted using the Mann-Whitney U test. Count data were represen-ted as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher's exact probability. Comparison of ordinal data was conducted using the rank sum test. Comparison of visual analog scores was analyzed using generalized estimating equations. Results:(1) Grouping of the enrolled patients. A total of 320 patients with colon cancer were screened for eligibility, including 156 males and 164 females, aged 68(59,73)years. All the 320 patients were allocated into the mesenteric fissure non-closure group with 164 cases and the mesenteric fissure closure group with 156 cases. There was no significant difference in the age, body mass index, American Society of Anesthesiologist score, maximum tumor diameter, anastomosis location, anastomosis method, surgical approach, range of lymph node dissection, tumor staging between the two groups ( P>0.05) and there was a significant difference in the sex between them ( P<0.05). (2) Intraoperative conditions. There was no significant difference between the mesenteric fissure closure group and the mesenteric fissure non-closure group in the volume of intraoperative blood loss, operation time, conversion to laparotomy, intraoperative complication ( P>0.05). Three patients in the mesenteric fissure non-closure group were converted to laparotomy. One patient in the mesenteric fissure closure group was converted to laparotomy, and 2 cases with intraoperative complication were mesenteric hematoma. (3) Postoperative conditions. There was no significant difference between the mesenteric fissure non-closure group and the mesenteric fissure closure group in the overall postoperative complications ( χ2=0.28, P>0.05). There was no significant difference in the occurrence of postoperative intestinal obstruction, abdominal distension, ascites, pleural effusion, gastric paralysis, anastomotic bleeding, anastomotic leakage, or surgical wound infection between the two groups ( P>0.05). There was no significant difference between the two groups in the reoperation, postoperative gastric tube replacement. There was no significant differ-ence in time to postoperative first flatus, time to postoperative initial liquid food intake, time to post-operative resumption of bowel movements, duration of postoperative hospital stay, total hospital expenses between the two groups ( Z=-0.01, 0.43, 1.04, -0.54, -0.36, P>0.05). One patient in the mesenteric fissure non-closure group received reoperation. No perioperative internal hernia or death occurred in either group. The visual analog score decreased with time in both groups. There was no significant difference in the visual analog score between the mesenteric fissure closure group and the mesenteric fissure non-closure group [ β=-0.20(-0.53,0.13), P>0.05]. Conclusion:Compared with closure of mesenteric fissure, non-closure of mesenteric fissure during laparoscopic right hemi-colectomy dose not increase perioperative complications or postoperative management risk.

Cornus officinalis,a medicinal and edible plant known for its liver-nourishing properties,has shown promise in inhibiting the activation of hepatic stellate cells(HSCs),crucial indicators of hepatic fibrosis,especially when processed by high pressure wine steaming(HPWS).Herein,this study aims to investigate the regulatory effects of cornus officinalis,both in its raw and HPWS forms,on inflammation and apoptosis in liver fibrosis and their underlying mechanisms.In vivo liver fibrosis models were established by subcutaneous injection of CCl4,while in vitro HSCs were exposed to transforming growth factor-β(TGF-β).These findings demonstrated that cornus officinalis with HPWS conspicuously ameliorated his-topathological injury,reduced the release of proinflammatory factors,and decreased collagen deposition in CCl4-induced rats compared to its raw form.Utilizing ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer(UHPLC-QTOF-MS)combined with network analysis,we identified that the pharmacological effects of the changed components of cornus officinalis before and after HPWS,primarily centered on the adenosine phosphate(AMP)-activated protein kinase(AMPK)pathway.Of note,cornus officinalis activated AMPK and sirtuin 3(SIRT3),promoting the apoptosis of activated HSCs through the caspase cascade by regulating caspase3,caspase6 and caspase9.small interfering RNA(siRNA)experiments showed that cornus officinalis could regulate AMPK activity and its mediated-apoptosis through SIRT3.In conclusion,cornus officinalis exhibited the ability to reduce inflammation and apoptosis,with the SIRT3-AMPK signaling pathway identified as a potential mecha-nism underlying the synergistic effect of cornus officinalis with HPWS on anti-liver fibrosis.

Objective To investigate the expression of CD123 in children with acute lymphoblastic leukemia(ALL)and its effect on the clinical characteristics and prognosis of children with B-lineage acute lymphoblastic leukemia(B-ALL).Methods A retrospective analysis was conducted on the clinical data of 251 children with ALL who were admitted to the Department of Hematology and Oncology,Children's Hospital of Kunming Medical University,from December 2019 to June 2022.According to the expression of CD123 at initial diagnosis,the children were divided into CD123+group and CD123-group,and the two groups were compared in terms of clinical characteristics and treatment outcome.The factors influencing the prognosis were analyzed.Results Among the 251 children with ALL,there were 146 children(58.2%)in the CD123+group.The B-ALL group had a significantly higher positive expression rate of CD123 than the acute T lymphocyte leukemia group(P<0.05).Compared with the CD123-group,the CD123+group had significantly lower peripheral blood leukocyte count and percentage of juvenile cells and a significantly higher proportion of children with high hyperdiploid karyotype or an age of 1-10 years,with a relatively low proportion of children with E2A-PBX1 fusion gene(P<0.05).The multivariate Cox proportional-hazards regression model analysis showed that compared with the>10 years group,the 1-10 years group had a significantly higher overall survival rate(P<0.05),and compared with the high risk group,the moderate risk group had a significantly higher event-free survival rate in children with B-ALL(P<0.05).Conclusions CD123 is widely expressed in children with B-ALL,and positive expression of CD123 might be an indicator for good prognosis in children with B-ALL,which is of great significance for evaluating the efficacy of remission induction therapy and survival prognosis of children with B-ALL.
