BACKGROUND: Meningeal metastasis (MM) is a form of malignant metastasis where tumor cells spread from the primary site to the pia mater, dura mater, arachnoid, subarachnoid space, and other cerebrospinal fluid compartments. Lung cancer is one of the most common malignant tumor types with MM. MM not only signifies that the lung cancer has progressed to an advanced stage but also leads to a range of severe clinical symptoms due to meningeal involvement. Currently, the risk factors associated with the development of MM are not fully elucidated. The aim of this study was to investigate the risk factors for MM in patients with lung adenocarcinoma (LUAD) who underwent non-surgical interventions, in order to identify LUAD patients at high risk for MM. METHODS: This retrospective study analyzed the clinical data of patients diagnosed with LUAD at the First Affiliated Hospital of Zhengzhou University from January 2020 to July 2024. Missing data were imputed using multiple imputation methods, and risk factors were identified through LASSO, univariate, and multivariate Logistic regression analyses. RESULTS: A total of 170 patients with LUAD were included in this study and divided into two groups: 87 patients with MM and 83 patients without MM. Univariate and multivariate Logistic regression analyses revealed that younger age at diagnosis (P=0.004), presence of the epidermal growth factor receptor (EGFR) L858R gene mutation (P=0.008), and concurrent liver metastasis at baseline (P=0.004) were independent risk factors for developing MM in LUAD patients who did not undergo surgical intervention. Conversely, higher baseline globulin levels (P=0.039) and the presence of the anaplastic lymphoma kinase (ALK) gene mutation (P=0.040) were associated with a reduced risk of MM development. CONCLUSIONS Age at diagnosis, EGFR L858R mutation status, ALK gene mutation status, concurrent liver metastasis, globulin levels at baseline were significantly associated with the risk of developing MM in patients with LUAD patients who did not undergo surgical intervention. For patients diagnosed at a younger age, carrying the EGFR L858R mutation, or presenting with baseline liver metastasis, early implementation of tertiary prevention strategies for MM is crucial. Regular monitoring of MM status should be conducted in these high-risk groups.

Objective To explore the effect of composite electromagnetic stimulation combined with chin tuck against resistance(CTAR)on post-stroke dysphagia.Methods From January,2021 to December,2023,156 post-stroke patients with pharyngeal dysphagia in the First Peo-ple's Hospital of Yibin were randomly divided into CTAR group(n=51),neuromuscular electrical stimulation(NMES)+repetitive transcranial magnetic stimulation(rTMS)group(n=52)and combination group(n=53).On the basis of routine swallowing function training,they received CTAR,NMES+rTMS and NMES+rTMS+CTAR,respectively,for four weeks.They were assessed with Functional Oral Intake Scale(FOIS),Standardized Swal-lowing Assessment(SSA),Swallowing-Quality of Life(SWAL-QOL),Rosenbek Penetration Aspiration Scale(PAS),video fluoroscopic swallowing study(VFSS)(including the score of VFSS,pharyngeal transit time,and upward and forward displacement of hyoid bone),average surface electromyography(AMEG)of submental and hyoid muscles,before and after treatment.Results The inter-group effect,intra-group effect and interaction effect were significant in SSA,SWAL-QOL and AMEG of the two muscles(F>6.611,P<0.001).The inter-group effect and interaction effect were significant in FOIS,VFSS,pharyngeal transit time,upward displacement of hyoid bone and forward displacement of hyoid bone(F>3.451,P<0.05).Pairwise comparison results showed that pharyngeal transit time was shorter in the combination group than in NMES+rTMS group(P=0.048),forward displacement of hyoid bone was more in the combina-tion group than in CTAR group(P=0.002),and AMEG was higher in the combination group than in CTAR group and NMES+rTMS group(P<0.001).There was significant difference in the score of PAS among three groups(Hc=8.282,P=0.016),and it was the best in the combination group.Conclusion The combination of NMES+rTMS and CTAR is superior to single electromagnetic stimulation or CTAR in the treatment of post-stroke sysphagia.

Objective To observe the clinical efficacy of Jin's triple-needle therapy combined with bilateral high-frequency repetitive transcranial magnetic stimulation in the treatment of post-stroke hemiplegia.Methods A total of 116 patients diagnosed with post-stroke hemiplegia and admitted to the wards and outpatient clinics of Yan'an City Hospital of Traditional Chinese Medicine from January 2023 to June 2024 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 58 patients in each group.The control group received bilateral high-frequency repetitive transcranial magnetic stimulation,while the observation group received Jin's triple-needle therapy in addition to the control group's treatment.After 30-day treatment,the clinical efficacy of the two groups was evaluated.Changes in traditional Chinese medicine(TCM)syndrome scores,Fugl-Meyer Assessment(FMA)scores for limb motor function,and Stroke-Specific Quality of Life(SS-QOL)scores were observed before and after treatment.Changes in neuron-specific enolase(NSE),glial fibrillary acidic protein(GFAP),and central nervous system-specific protein(S100-β)levels were compared between the two groups before and after treatment.The safety and incidence of adverse reactions in both groups were also evaluated.Results(1)The total effective rate in the observation group was 91.38%(53/58),compared to 75.86%(44/58)in the control group.The observation group showed significantly better efficacy than the control group,with a statistically significant difference(P＜0.05).(2)After treatment,both groups showed significant improvements in TCM syndrome scores and FMA scores for limb motor function(P＜0.05),and the observation group was significantly superior to the control group in improving TCM syndrome scores and FMA scores,with a statistically significant difference(P＜0.05).(3)After treatment,both groups showed significant improvementss(P＜0.05)in NSE,GFAP,and S100-β level,and the observation group was significantly superior to the control group in improving NSE,GFAP,and S100-β levels,with a statistically significant difference(P＜0.05).(4)After treatment,both groups showed significant improvements in SS-QOL scores for quality of life(P＜0.05),and the observation group was significantly superior to the control group in improving SS-QOL scores,with a statistically significant difference(P＜0.05).(5)The incidence of adverse reactions in the observation group was 12.07%(7/58),compared to 8.62%(5/58)in the control group.There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Jin's triple-needle therapy combined with bilateral high-frequency repetitive transcranial magnetic stimulation can significantly improve clinical symptoms,enhance limb motor function,reduce levels of brain injury markers,and improve the quality of life in patients with post-stroke hemiplegia.The treatment is safe and shows significant efficacy.

ObjectiveTo investigate the effect of the expression of HBcAg in hepatocytes on the serum level of HBcAb and seroconversion of HBeAg after antiviral therapy with nucleos(t)ide analogues (NUCs). MethodsSerum samples and liver tissue paraffin sections were collected from 101 chronic hepatitis B (CHB) patients who received antiviral therapy with NUCs in Nanfang Hospital and Panyu Central Hospital from January 2015 to June 2018. ELISA was used to measure the serum level of HBcAb, and immunohistochemistry was used to measure the expression of HBcAg in the liver. The GEO database (GSE96851) was analyzed to obtain differentially expressed genes in the liver of patients with HBcAg-positive hepatitis. The two-independent-samples t test was used for comparison of continuous data between two groups; the multiple-independent-samples nonparametric Kruskal-Wallis H test was used for comparison of continuous data between multiple groups, and Dunnett method was used for further comparisons; the chi-square test was used for comparison of categorical data between groups. ResultsThe expression pattern of HBcAg in hepatocytes was classified as absent expression, nuclear expression, cytoplasmic expression, and nuclear/cytoplasmic expression, and according to expression level, HBcAg expression was classified as grades Ⅰ, Ⅱ, Ⅲ, and Ⅳ expression. HBeAg seroconversion rates after 96 weeks of antiviral therapy were 5.88%, 16.67%, 22.73%, and 24.24%, respectively, in the patients with absent expression, nuclear expression, cytoplasmic expression, and nuclear/cytoplasmic expression (χ2=4753, P=0.037), and HBeAg seroconversion rates after 96 weeks of antiviral therapy were 5.88%, 13.04%, 27.59%, and 26.67%, respectively, in the patients with grade Ⅰ, Ⅱ, Ⅲ, and Ⅳ expression (χ2=6.580, P=0.016). There were significant differences in the serum levels of HBcAb-IgM and total HBcAb between the patients with absent expression, nuclear expression, cytoplasmic expression, and nuclear/cytoplasmic expression of HBcAg (HBcAb-IgM: H=9.760, P=0.021; total HBcAb: H=21.46, P＜0.001), and there were also significant differences in the serum levels of HBcAb-IgM and total HBcAb between the patients with grade Ⅰ, Ⅱ, Ⅲ, and IV expression of HBcAg (HBcAb-IgM: H=18.80, P＜0.001; total HBcAb: H=26.03, P＜0.001). The analysis of differentially expressed genes in the liver showed that the expression of antibody-related genes was upregulated in the liver of patients with HBcAg-positive acute liver failure. ConclusionThe expression pattern and level of HBcAg in the cytoplasm of hepatocytes are associated with serum HBcAb, and the measurement of HBcAg may help to predict the efficacy of antiviral therapy with NUCs.

Objective    To explore the efficacy of artificial intelligence (AI) detection on pulmonary nodule compared with multidisciplinary team (MDT) in regional medical center. Methods    We retrospectively analyzed the clinical data of 102 patients with lung nodules in the Xiamen Fifth Hospital from April to December 2020. There were 57 males and 45 females at age of 36-90 (48.8±11.6) years. The preoperative chest CT was imported into AI system to record the detected lung nodules. The detection rate of pulmonary nodules by AI system was calculated, and the sensitivity, specificity of AI in the different diagnosis of benign and malignant pulmonary was calculated and compared with manual film reading by MDT. Results    A total of 322 nodules were detected by AI software system, and 305 nodules were manually detected by physicians (P<0.05). Among them, 113 pulmonary nodules were diagnosed by pathologist. Thirty-eight of 40 lung cancer nodules were AI high-risk nodules, the sensitivity was 95.0%, and 25 of 73 benign nodules were AI high-risk nodules, the specificity was 65.8%. Lung cancer nodules were correctly diagnosed by MDT, but  benign nodules were still considered as  lung cancer at the first diagnosis in 10 patients. Conclusion    AI assisted diagnosis system has strong performance in the detection of pulmonary nodules, but it can not content itself with clinical needs in the differentiation of benign and malignant pulmonary nodules. The artificial intelligence system can be used as an auxiliary tool for MDT to detect pulmonary nodules in regional medical center.

[Abstract] Objective: To construct a circRNA profile of esophageal squamous cell carcinoma (ESCC) and analyze differentially expressed circRNAs. Methods: Samples were taken from 3 patients with esophageal squamous cell carcinoma who were hospitalized in the Department of Thoracic Surgery, Jintan Hospital, Jiangsu University from June 2018 to February 2019. The circRNA expression profile was constructed by high-throughput sequencing technique, and the circRNA differentially expressed in 3 pairs of esophageal squamous cell carcinoma tissues and adjacent tissues was detected. The biological functions and related signal pathways of these circRNA were analyzed by GO and KEGG techniques. Results: By comparing the expression levels of circRNA between esophageal squamous cell carcinoma and adjacent tissues, 905 differentially expressed circRNA were found, of which 404 were up-regulated and 501 were down-regulated. hsa_circ_0004390 was the CIRC RNA with the highest up-regulation factor (FC=7.9712), and novel_circ_0012687 was the one with the highest down-regulation factor. GO and KEGG analysis showed that these circRNA may be involved in biological processes such as cell cycle, cell components and protein binding of cancer cells, and signal pathways such as Hippo and cGMP-PKG. Conclusion: The expression profile analysis of circRNA in esophageal squamous cell carcinoma showed that the significantly differentially expressed circRNA could be used as a potential biomarker of esophageal squamous cell carcinoma.

Objective: To analysis the incidence and relevant clinical factors of colorectal polyps and adenomas in population of health examination. Methods: Colonoscopy results and clinical data of 615 cases undergoing health examination from January 2018 to March 2019 were analyzed retrospectively in International Medical Center, Beijing Friendship Hospital, Capital Medical University.There were 436 males and 179 females, average age 47.38 years, aged 18-81 years. The clinical data contained sex, age, smoking history, drinking history, body mass index.Chi-square test and trend chi-square test were used to compare the differences of polyp detection rate and adenoma detection rate in different populations. Multivariate Logistic regression analysis were applied to explore the potential factors associated with the polyp detection rate and adenoma detection rate. Results: Two hundred and forty cases(39.02%) with colorectal disease were checked out, include 206 cases(33.50%) with colorectal polyps and 138 cases(22.44%) with colorectal adenomas. In the detection rate of colorectal polyps, male were higher than female[36.70%(160/436) vs 25.70%(46/179), χ²=6.89, P<0.05], smokers were higher than non-smokers[42.35%(108/255) vs 27.22%(98/360), χ²=15.34, P<0.001], and drinkers were higher than non-drinkers[40.67%(109/268) vs 27.95%(97/347), χ²=10.98, P<0.05]. With the increase of age, the detection rate of colorectal polyps increased significantly(χ²=24.19, P<0.001). With the increase of body mass index, the detection rate of colorectal polyps increased significantly(χ²=16.88, P<0.001). In the detection rate of colorectal adenoma, smokers were higher than non-smokers[28.24%(72/255) vs 18.33%(66/360), χ²=7.31, P<0.05], and drinkers were higher than non-drinkers[27.61(74/268)% vs 18.44%(64/347), χ²=7.30, P<0.05]. With the increase of age, the detection rate of colorectal adenoma increased significantly(χ²=15.87, P<0.001). With the increase of body mass index, the detection rate of colorectal adenoma increased significantly (χ²=13.30, P<0.001). There was no significant difference in the detection rate of colorectal adenomas between male and female[24.31%(106/436) vs 17.88%(32/179), χ²=3.02, P>0.05]. Multivariate Logistic regression analysis showed that age increasing, body mass index increasing, smoking and alcohol consumption were risk factors for colorectal polyps and adenomas. Conclusions The detection rate of colorectal polyps and adenomas are related with sex, age, smoking, drinking and body mass index. Age increasing, body mass index increasing and smoking are the risk factors for colorectal polyps, age increasing and body mass index increasing are the risk factors for colorectal adenomas.
