Objective: : This study analyzed the influence of p120-catenin (catenin [cadherin-associated protein], delta 1 [CTNND1]) on the malignant characteristics of glioma and elucidated the potential underlying mechanism. Methods: : The p120 expression level was assessed in the brain tissues of 42 glioma patients and 10 patients with epilepsy by using the immunohistochemical method. Meanwhile, quantitative polymerase chain reaction (QT-PCR) technology was employed to assess the expression of p120 in the brain tissues of 71 glioma patients and 13 epilepsy patients. LN229, U251, and U87 glioma cells were used for in vitro analysis and categorized into four treatment groups : siRNA-blank control (BC) group (no RNA sequence was transfected), siRNA-negative control (NC) group (transfected control RNA sequences with no effect), and siRNA-1 and siRNA-2 groups (two p120-specific interfering RNA transfection). p120 expression in these treatment groups was quantified by western blotting assay. The migratory and invasive capabilities of glioma cells were studied by wound healing assay and Transwell invasion assay, respectively, under different treatment conditions. MTT (3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide) assay and cell cycle and apoptosis assay were used to determine glioma cell proliferation and apoptosis, respectively. Enzymelabeled assay was performed to measure intracellular calcium ion concentration. Immunofluorescence assay was performed for determining microtubule formation and glioma cell distribution. Results: : Brain tissues of the glioma group exhibited a remarkable increase in the p120 expression level as compared to brain tissues of the nontumor group (p<0.05). Furthermore, a strong positive correlation was noted between the malignancy degree in glioma brain tissues and p120 expression in Western blotting (r=0.906, p<0.0001) and QT-PCR (F=830.6, p<0.01). Compared to the BC and NC groups, the siRNA transfection groups showed a significant suppression in p120 expression in glioma cells (p<0.05), with a marked attenuation in the invasive, migratory, and proliferative capabilities of glioma cells as well as an increase in apoptotic potential (p<0.05). Enzyme-labeled assay showed a remarkable increase in calcium concentration in glioma cells after siRNA treatment. Immunofluorescence assay revealed that the microtubule formation ability of glioma cells reduced after siRNA treatment. Conclusion : p120 has a pivotal involvement in facilitating glioma cell invasion and proliferation by potentially modulating these processes through its involvement in microtubule formation and regulation of intracellular calcium ion levels.

AIM: To compare the efficacy of intravitreal injection of ranibizumab(IVR)and intravitreal injection of conbercept(IVC)in children with retinopathy of prematurity(ROP).METHODS: Retrospective study. A total of 1 100 eyes with ROP treated with intravitreal anti-VEGF at our hospital from January 2015 to June 2023 were included. According to the different therapeutic drugs, the children were divided into two groups: IVR group and IVC group. According to the degree of ROP, the patients were divided into three groups: aggressive ROP(A-ROP), Zone Ⅰ type 1 ROP and Zone Ⅱ type 1 ROP. The reactivation and retreatment between the two groups were compared after propensity score matching(PSM)analysis, and they were followed-up for at least 3 mo after surgery.RESULTS: In Zone Ⅱ type 1 ROP, there was a statistically significant difference in the rates of reactivation and retreatment between the IVR and IVC groups(P<0.05); however, in A-ROP and Zone I type 1 ROP, there were no statistically significant differences in the rates of reactivation and retreatment between the two groups(P>0.05). The risk of reactivation and retreatment of Zone I type 1 ROP was higher than the Zone II type 1 ROP. Furthermore, the use of drugs and corrected gestational age of first treatment were influencing factors of lesion recurrence and retreatment.CONCLUSION: There is a significant difference in the initial cure effect between the two drugs in Zone II type 1 ROP, with the reactivation and retreatment rates of the IVC group being much lower than those of the IVR group.

Objective:To screen the main characteristic variables affecting the incidence of cardiovascular and cerebrovascular diseases,and to construct the Bayesian network model of cardiovascular and cerebrovascular disease incidence risk based on the top 10 characteristic variables,and to provide the reference for predicting the risk of cardiovascular and cerebrovascular disease incidence.Methods:From the UK Biobank Database,315 896 participants and related variables were included.The feature selection was performed by categorical boosting(CatBoost)algorithm,and the participants were randomly divided into training set and test set in the ratio of 7∶3.A Bayesian network model was constructed based on the max-min hill-climbing(MMHC)algorithm.Results:The prevalence of cardiovascular and cerebrovascular diseases in this study was 28.8％.The top 10 variables selected by the CatBoost algorithm were age,body mass index(BMI),low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),the triglyceride-glucose(TyG)index,family history,apolipoprotein A/B ratio,high-density lipoprotein cholesterol(HDL-C),smoking status,and gender.The area under the receiver operating characteristic(ROC)curve(AUC)for the CatBoost training set model was 0.770,and the model accuracy was 0.764;the AUC of validation set model was 0.759 and the model accuracy was 0.763.The clinical efficacy analysis results showed that the threshold range for the training set was 0.06-0.85 and the threshold range for the validation set was 0.09-0.81.The Bayesian network model analysis results indicated that age,gender,smoking status,family history,BMI,and apolipoprotein A/B ratio were directly related to the incidence of cardiovascular and cerebrovascular diseases and they were the significant risk factors.TyG index,HDL-C,LDL-C,and TC indirectly affect the risk of cardiovascular and cerebrovascular diseases through their impact on BMI and apolipoprotein A/B ratio.Conclusion:Controlling BMI,apolipoprotein A/B ratio,and smoking behavior can reduce the incidence risk of cardiovascular and cerebrovascular diseases.The Bayesian network model can be used to predict the risk of cardiovascular and cerebrovascular disease incidence.

Objective:Abnormal immune system activation and inflammation are crucial in causing Parkinson's disease.However,we still don't fully understand how certain immune-related genes contribute to the disease's development and progression.This study aims to screen key immune-related gene in Parkinson's disease based on weighted gene co-expression network analysis(WGCNA)and machine learning. Methods:This study downloaded the gene chip data from the Gene Expression Omnibus(GEO)database,and used WGCNA to screen out important gene modules related to Parkinson's disease.Genes from important modules were exported and a Venn diagram of important Parkinson's disease-related genes and immune-related genes was drawn to screen out immune related genes of Parkinson's disease.Gene ontology(GO)analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)were used to analyze the the functions of immune-related genes and signaling pathways involved.Immune cell infiltration analysis was performed using the CIBERSORT package of R language.Using bioinformatics method and 3 machine learning methods[least absolute shrinkage and selection operator(LASSO)regression,random forest(RF),and support vector machine(SVM)],the immune-related genes of Parkinson's disease were further screened.A Venn diagram of differentially expressed genes screened using the 4 methods was drawn with the intersection gene being hub nodes(hub)gene.The downstream proteins of the Parkinson's disease hub gene was identified through the STRING database and a protein-protein interaction network diagram was drawn. Results:A total of 218 immune genes related to Parkinson's disease were identified,including 45 upregulated genes and 50 downregulated genes.Enrichment analysis showed that the 218 genes were mainly enriched in immune system response to foreign substances and viral infection pathways.The results of immune infiltration analysis showed that the infiltration percentages of CD4+ T cells,NK cells,CD8+ T cells,and B cells were higher in the samples of Parkinson's disease patients,while resting NK cells and resting CD4+ T cells were significantly infiltrated in the samples of Parkinson's disease patients.ANK1 was screened out as the hub gene.The analysis of the protein-protein interaction network showed that the ANK1 translated and expressed 11 proteins which mainly participated in functions such as signal transduction,iron homeostasis regulation,and immune system activation. Conclusion:This study identifies the Parkinson's disease immune-related key gene ANK1 via WGCNA and machine learning methods,suggesting its potential as a candidate therapeutic target for Parkinson's disease.

Background Fine particulate matter (PM_2.5) is a serious air pollutant associated with elevated levels of C-reactive protein (CRP), an inflammatory indicator. Objective To assess the potential impacts of long-term exposure to PM_2.5 on CRP levels based on previous epidemiological studies. Methods PubMed, Embase, Web of Science, CNKI, and Wanfang databases were searched to screen the cohort studies published from January 1, 2000 to January 1, 2022 on the effects of long-term exposure to PM_2.5 on CRP levels. "Fine Particulate Matter", "PM_2.5", "Particulate Air Pollutants", "Ambient Particulate Matter", "CRP", "C-reactive Protein", and "High Sensitivity C-reactive Protein" in English or Chinese were the key words used in the search. The percentage change in CRP level per 10 μg·m⁻³ increase in PM_2.5 concentration in each study was extracted, followed by meta-analysis, subgroup analysis, and sensitivity analysis. Results A total of 1241 articles were retrieved, and 7 articles were included. Random-effects models were used to merge the included data, and it was found that the percentage of CRP level increased by 10.41% (95%CI: 2.24%-18.57%, P<0.05), when PM_2.5 concentration increased by 10 μg·m⁻³, І²=84.2%. The subgroup analysis conducted with grouping based on the annual mean concentration of PM_2.5 long-term exposure showed that the intra-group heterogeneity was significantly reduced in the <15 μg·m⁻³ and the 15- μg·m⁻³ groups, and the subgroup forest analysis showed differences between the two groups. The results of sensitivity analysis showed that there was a high degree of heterogeneity among the 7 studies, and the 2 papers with the highest annual average PM_2.5 concentration were the sources of heterogeneity. The Egger test and the funnel plot indicated that no obvious publication bias was found. Conclusion Long-term exposure to PM_2.5 can raise levels of CRP in human body.

Objective: To analyze the characteristics of stress symptoms before and after surgery in adolescent idiopathic scoliosis (AIS) patients and their correlation with postoperative pain. Methods: Fifty-four AIS patients aged 13-18 years from January 2015 to June 2018 in Foshan Traditional Chinese Medicine Hospital were selected. The anxiety, stress and stress symptoms of the patients before and 6 months after operation were assessed by the Trauma Symptom Checklist for Children-Alternative version (TSCC-A) and the Youth Self-Report (YSR). The pain was assessed by Visual Analogue Scale. The correlation between the stress symptoms of the patients and postoperative pain were analyzed by linear regression equation. Results: The score of anxiety/depression and internalization problems in YSR before operation was (5.40±2.48) and (12.19±4.67) respectively, and 6 months after operation, the score was (4.10±1.92) and (9.81±3.46) respectively, there were significant differences between preoperative and 6 months after operation (t value was 7.266, 8.107, P < 0.05). Before operation, the scores of anger in TSCC-A, the scores of social problems and attention problems in YSR were positively correlated with postoperation pain (P < 0.05), while postoperation pain was positively correlated with the scores of anxiety in TSCC-A, the scores of social problems and attention problems in YSR 6 months after operation (P < 0.05). Conclusions Preoperative stress symptoms of AIS patients are associated with postoperative pain, while postoperative pain is associated with postoperative recovery anxiety. Preoperative intervention should be actively taken to reduce perioperative stress symptoms and postoperative pain, so as to further improve the quality of nursing.

Objective:To explore the preventive effect of moxibustion on six acupoints around the knee on perioperative deep venous thrombosis (DVT) of the lower extremity in patients undergoing total knee arthroplasty.Methods:Using the convenient sampling method, a total of 80 patients who underwent single total knee arthroplasty in Foshan Hospital of Traditional Chinese Medicine in Guangdong Province from January 2018 to October 2019 were selected as the research objects. According to the random number table method, they were divided into the control group and the observation group with 40 cases in each group. The control group was given conventional treatments and nursing such as subcutaneous injection of low molecular weight heparin calcium and the observation group was given moxibustion on six acupoints around the knee on the basis of the control group. Patients in the two groups were observed for 14 days. Changes in circumference difference of calf (before operation, 1, 7, 14 days after operation) , plasma prothrombin time (PT) , activated partial thromboplastin time (APTT) and D-dimer were compared between two groups. DVT formation was compared between the two groups on the 14th day after surgery and satisfaction of patients was evaluated.Results:The differences in calf circumference of the operating limbs within each group were statistically significant on the first day after operation and before operation ( P<0.05) . There were statistically significant differences between the 7th and 14th day after operation and the first day after operation ( P<0.05) . There was no statistically significant difference in calf circumference difference between the two groups before and on the first day after the operation ( P>0.05) . The differences between the two groups on the 7th and 14th day after operation were statistically significant ( P<0.05) . There were statistically significant differences in PT, APTT and D-dimer on the first day after surgery and before surgery within each group ( P<0.05) , and there were statistically significant differences between the 7th and 14th day after surgery and the first day after surgery ( P<0.05) . There was no statistically significant difference in PT, APTT and D-dimer before operation and on the 1st and 7th day after operation between the two groups ( P>0.05) . On the 14th day after operation, the differences of PT, APTT, D-dimer between the two groups were statistically significant ( P<0.05) . A total of 6 patients (15.0%) in the control group had DVT, but no DVT occurred in the observation group, the total satisfaction rate of the observation group was higher than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Moxibustion on six acupoints around the knee can reduce the swelling of the lower limbs after operation, improve coagulation function and prevent the occurrence of DVT, which has higher satisfaction of patients.

Objective To explore the effects of perinatal infection on retinopathy of prematurity (ROP).Methods A retrospective cohort study was performed to analyzed the clinical data of 238 preterm infants at gestational age ≤32 weeks who were delivered in Guangdong Women and Children Hospital from November 2014 to October 2015 and ROP screening examinations.Observation was not terminated until they were 45 weeks of corrected gestational age.Mild ROP was defined as having stage 1 or stage 2 ROP in zone Ⅱ or Ⅲ without additional disease,and severe ROP was defined as stage 3 or higher,any ROP in zone Ⅰ,prethreshold/threshold,with additional disease,and aggressive posterior retinopathy of prematurity (AP-ROP).Medical records of eligible preterm infants were retrospectively reviewed and analyzed.Occurrences of ROP,severe ROP,and clinically significant ROP requiring surgical treatment were assessed.Results The mean gestational age of the cohort was (30.10 ± 1.34) weeks (25.29-32.00 weeks) and the mean birth weight was (1 373 ± 272) g(720 ～2 330 g).ROP was diagnosed in 76 of 238 infants (31.9％),including 39 cases with mild ROP (16.4％) and 37 cases with severe ROP (15.5％).Surgical treatment was performed on 22 infants (9.2％).In the patients with ROP,the time to develop ROP from birth was (35.16 ± 14.26) d and the mean time of its most serious stage was (44.62 ± 18.99) d.In 22 patients with ROP who required surgical treatment,the time of surgical treatment was (50.27 ± 17.24) d.In univariate analysis,maternal perinatal infection disease was found to be associated with ROP occurrence (x2 =7.891,P =0.005) and ROP progression requiring surgical treatment (x2 =4.494,P =0.034).Small gestational age,low birth weight and long-term oxygen therapy were found to be asso ciated with ROP occurrence and severe ROP (gestational age:t =-5.803,P ＜ 0.001;t =-5.290,P ＜ 0.001;t =-4.150,P ＜ 0.001;birth weight:t =-4.942,P ＜ 0.001;t =-4.058,P ＜ 0.001;t =-3.126,P =0.002;the duration of oxygen therapy:t =2.351,P =0.020;t =2.473,P =0.018).Apgar scores ≤ 7 at 1 min and 5 min were found to be associated with severe ROP (x2 =4.803,P =0.028).Neonatal sepsis and neonatal fungal infection were found to be associated with ROP occurrence (x2 =6.071,P =0.014;x2 =4.070,P =0.044).Neonatal fungal infection was also found to be associated with severe ROP (x2 =5.479,P =0.019).Multivariate regression analysis indicated that maternal perinatal infection disease was associated with an increased risk of ROP and ROP progression requiring surgical treatment (OR =2.837,P =0.023;OR =4.087,P =0.012).Maternal preeclampsia was also associated with an increased risk of ROP (OR =2.506,P =0.040).Gestational age was an important risk factor for the development of ROP.The smaller the gestational age was,the higher the rate of occurring ROP and severe ROP (OR =0.518,0.508,0.520,all P ＜ 0.001).Conclusions Both fetal and neonatal exposure to infection appear to contribute to the increase of ROP risk in the preterm infants at gestational age ≤ 32 weeks.Maternal perinatal infection disease and maternal preeclampsia were independently associated with ROP occurrence and ROP progression in the preterm infants at gestational age ≤32 weeks.
