Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Invasive angiomyxoma（AAM） is characterized by unclear boundaries, non enveloped glial growth, high recurrence rate, and belongs to a benign tumor, but it is invasive and grows slowly. A patient with recurrent left vestibular invasive angiomyxoma was admitted to the Otorhinolaryngology ward of Beijing Traditional Chinese Medicine Hospital Affiliated with Capital Medical University. The patient underwent two repeated surgeries and underwent a combined internal and external nasal approach for the removal of the nasal vestibular angiomyxoma. The patient recovered well after the surgery and has not recurred since follow-up.

OBJECTIVE Aimed to investigate the impact of comorbid asthma on chronic rhinosinusitis with nasal polyps(CRSwNP)and identify key proteins and signaling pathways.METHODS Proteomic methods were employed to analyze differentially expressed proteins(DEPs)in nasal lavage fluid(NLF)from control,CRSwNP,and CRSwNP with asthma groups.DIA quantitative analysis technology was used to assess the gradient changes of DEPs among the three groups to determine key proteins affected by comorbid asthma in CRSwNP.RESULTS Compared to the control group,1 377 and 1 006 DEPs were identified in the CRSwNP and CRSwNP with asthma groups,respectively.Peroxiredoxin-5(PRDX5),Ran-Binding Protein 1(RanBP1)(upregulated),and Keratin 9(KRT9)(downregulated)were identified as key proteins affecting CRSwNP with asthma.CONCLUSION Comorbid asthma may promote the occurrence and development of nasal polyps through specific key proteins and signaling pathways,providing new molecular insights into the interaction between CRSwNP and asthma.

Objective:To explore the current status and influencing factors of family resilience in primary caregivers of advanced cancer patients.Methods:A convenience sampling method was used to select the primary caregivers of advanced cancer patients from the Department of Gastrointestinal Oncology at Beijing Cancer Hospital, between July 2023 and March 2024. A questionnaire survey was conducted using a general information survey, the Family Hardiness Index, the General Self-Efficacy Scale, and subscales for intimacy, emotional expression, and conflict in the Family Environment Scale.Results:A total of 130 questionnaires were distributed, and 120 valid questionnaires were returned, resulting in an effective response rate of 92.31%. The family Hardiness Index score of the 120 primary caregivers was (61.03±6.44) , with scores for the responsibility dimension at (29.35±3.32) , the control dimension at (16.97±2.78) , and the challenge dimension at (14.72±2.17) . The General Self-Efficacy Scale score was (2.60±0.57) , and the Family Environment Scale scores were as follows: intimacy (8.13±1.45) , emotional expression (5.40±1.71) , and conflict 2.00 (1.00, 3.00) . Multiple linear regression analysis showed that emotional expression in the family environment ( P=0.001) , self-efficacy ( P<0.001) , and marital status ( P=0.017) were significant factors influencing family resilience in primary caregivers, explaining 27.2% of the total variance. Conclusions:The family resilience of primary caregivers of advanced cancer patients is at a moderate to high level. Caregivers with spouses, better emotional expression among family members, and higher self-efficacy tend to have higher levels of family resilience.

The expression levels of lncRNA CRNDE, miR-181a-5p and ATG5 mRNA were detected by real-time fluorescence quantification (RT-qPCR) and the expression level of ATG5 protein was detected by Western-blot. The expression levels of lncRNA CRNDE, miR-181a-5p, ATG5 mRNA were compared among the three groups and correlated with clinical indices, and a subject operating characteristic curve (ROC) was constructed to assess the value of lncRNA CRNDE, miR-181a-5p, ATG5 mRNA in the diagnosis of gout. Measurements conforming to normal distribution were analyzed using t test or ANOVA, data with non-normal distribution was analyzed using Mann-Whitney U test or Kruskal-Wallis H test, correlation analysis between variables was analyzed using Spearman's analysis, and the diagnostic value of each indicator was analyzed using ROC curve. Results:① The differences in the expression of lncRNA CRNDE, miR-181a-5p, and ATG5 mRNA between the three groups were statistically significant ( H=32.12, 57.73, 68.32, all P<0.001). Among them, lncRNA CRNDE expression level in the AG group was significantly higher than that in the IG group and healthy control group [61.95(11.39, 108.30)×10 -3, 25.71(15.40, 38.40)×10 -3, 13.80(3.97, 23.99)×10 -3; Z=-3.24, P=0.001; Z=-5.03, P<0.001], and the expression level of IG group was higher than that of healthy control group( Z=-3.56, P<0.001); miR-181a-5p and ATG5 mRNA expression levels in AG group were significantly lower than those in IG group and healthy control group [miR-181a-5p: 39.81(31.22, 69.38)×10 -3, 60.74(44.19, 90.35)×10 -3, 121.30(101.50, 316.90)×10 -3; Z=-3.01, P=0.030; Z=-6.93, P<0.001. ATG5 mRNA: 4.52(2.31, 26.63)×10 -3, 43.63(13.72, 102.70)×10 -3, 153.90(66.62, 365.80)×10 -3; Z=-5.47, -7.36, all P<0.001)], which were expressed at lower levels in the IG group than in the healthy controls ( Z=-5.25, -4.47, all P<0.001). The difference of ATG5 protein expression level among the three groups expressed was statistically significant ( F=6.24, P=0.030), and the AG group was higher than the healthy control group, and the difference was statistically significant [(0.96±0.13) vs.(0.61±0.04), t=4.25, P=0.013], but the difference between the IG group (0.78±0.15) and the AG group and the HC group was not statistically significant ( t=1.51, P=0.206; t=1.85, P=0138). ② Spearman correlation analysis showed that lncRNA CRNDE was negatively correlated with the expression levels of miR-181a-5p and ATG5 mRNA in gout patients ( r=-0.49, P<0.001; r=-0.35, P=0.002); miR-181a-5p was positively correlated with ATG5 mRNA expression levels ( r=0.64, P<0.001); lncRNA CRNDE expression level was positively correlated with ESR and WBC ( r=0.49, P<0.001; r=0.43, P=0.001); miR-181a-5p expression level was negatively correlated with ESR and WBC ( r=-0.29, P=0.009; r=-0.35, P=0.002), and ATG5 mRNA expression levels were negatively correlated with ESR, WBC, and GR ( r=-0.26, P=0.021; r=-0.26, P=0.024; r=-0.27, P=0.021). In the AG group lncRNA CRNDE was positively correlated with ESR and WBC ( r=0.36, P=0.022; r=0.36, P=0.026) and miR-181a-5p was negatively correlated with WBC ( r=-0.34, P=0.038) ③ ROC curve showed that the areas under ROC curve of lncRNA CRNDE, miR-181a-5p and ATG5 mRNA expression levels to predict gout were 0.764, 0.875 and 0.864, respectively. The area under ROC curve of gout predicted by the three combined was 0.928. Conclusion:lncRNA CRNDE, miR-181a-5p, and ATG5 may be involved in the pathoge-nesis of primary gouty arthritis, and are potential biological parameters for studying the pathogenesis of gout.

Objective:To construct a classification model for endoscopic ultrasonography (EUS) images of gastrointestinal stromal tumors (GISTs) and leiomyomas (LM) based on deep learning technology, and to verify its value for differential diagnosis.Methods:From October 2014 to October 2021, 69 patients of GISTs and 73 of LM who underwent EUS and were pathologically confirmed by surgery or endoscopic resection in the Second Affiliated Hospital of Soochow University were retrospectively studied. One clear EUS image with typical lesion was selected for each case. Using the hold-out method, the images of each disease were divided into the training set and the validation set according to the ratio of the number of images in the training set to the number of images in the validation set, which was 8∶2. Finally, 113 EUS images (55 GISTs and 58 LM) were used to form the training set, and 29 EUS images (14 GISTs and 15 LM) were used to form the validation set. The training set was used to train and optimize the deep learning model, and the validation set was used to verify the classification model. The main observation indicators included the sensitivity, the specificity, the positive predictive value, the negative predictive value and the accuracy of differential diagnosis.Results:The accuracy of the classification model established by Resnet 34 network structure in the differential diagnosis of GISTs and LM tended to be 0.89, better than the classification model established by Resnet 50 network structure (0.81). The sensitivity, the specificity, the positive predictive value, the negative predictive value and the accuracy of the classification model based on Resnet 34 network structure for differentiating EUS images in the validation set were 85.71% (12/14, 95% CI: 67.38%-100.00%), 93.33% (14/15, 95% CI: 80.71%-100.00%), 92.31% (12/13, 95% CI: 77.82%-100.00%), 87.50% (14/16, 95% CI: 71.30%-100.00%) and 89.66% (26/29, 95% CI: 78.57%-100.00%), respectively. Conclusion:It is feasible to use deep learning technology in the differential diagnosis of EUS images of GISTs and LM, which can provide auxiliary diagnostic opinions for clinicians. The deep learning model based on Resnet 34 network structure shows higher accuracy in the differential diagnosis of EUS images of GISTs and LM.

Objective:To investigate the expression level of long non-coding RNA (lncRNA) CTC-338M12.4 in tongue squamous cell carcinoma tissues, and its effects on the cell cycle, cell proliferation, and migration of tongue squamous cell carcinoma cells in vitro as well as its molecular mechanisms.Methods:The Gene Expression Omnibus (GEO) database was used to obtain the lncRNA series data set GSE139869, and the differential expression of CTC-338M12.4 in tongue squamous cell carcinoma tissues and adjacent tissues was analyzed. The transcriptional expression levels of CTC-338M12.4 in human immortalized oral keratinocytes (HOK) and tongue squamous cell carcinoma cell lines HN13, TSCCa, CAL-27, Tca8113, SCC15 were detected by using reverse transcription quantitative real-time polymerase chain reaction (qRT-PCR). CAL-27 cells with the lowest expression level of CTC-338M12.4 were selected and were divided into the control group (co-transfected with vectors containing negative sequence) and CTC-338M12.4 group (co-transfected with CTC-338M12.4 overexpression vectors). The proliferation ability of CAL-27 cells in each group was detected by using cell colony formation assay, and the cell cycle distribution of CAL-27 cells was detected by using flow cytometry. The migration ability of CAL-27 cells was detected by using scratch test. The lncACTdb database was used to predict the complementary binding sites between CTC-338M12.4 and miRNA-27a-5p (miR-27a-5p), and dual-luciferase reporter gene assay was used to verify. The expression level of miR-27a-5p in CAL-27 cells of all groups was detected by using qRT-PCR. The protein expression level of related factors on JAK/STAT signaling pathway in CAL-27 cells of all groups was detected by using Western blot.Results:Analysis of GEO database data showed that transcriptional level CTC-338M12.4 in tongue squamous cell carcinoma tissues was lower than that in adjacent tissues, and the difference was statistically significant ( P < 0.01). Transcriptional level CTC-338M12.4 in tongue squamous cell carcinoma HNl3, TSCCa, CAL-27, Tca8113, and SCC15 cells was lower than that in HOK cells, and the differences were statistically significant (all P < 0.05). The transcriptional level relative expression level of CTC-338M12.4 in CAL-27 cells in the CTC-338M12.4 group was higher than that in the control group, and the difference was statistically significant ( P < 0.01). Cell colony formation assay showed that the colong number of CAL-27 cell in the CTC-338M12.4 group was less than that in the control group [(51±10) vs. (114±21)], and the difference was statistically significant ( t = 2.71, P = 0.035). Flow cytometry showed that the proportion of G 0/G 1 phase cells in CAL-27 cells in the CTC-338M12.4 group was higher than that in the control group [(64±3)% vs. (43±4)%], and the difference was statistically significant ( t = 4.87, P = 0.003). The scratch test showed that when scratching, the scratch width of both groups was similar ( P > 0.05); after scratch for 25 h, the scratch width of CAL-27 cells in the CTC-338M12.4 group was wider than that in the control group [(133±15) μm vs. (64±10) μm], and the difference was statistically significant ( t = 3.78, P = 0.009). The dual luciferase reporter gene assay showed that the relative luciferase activity of CAL-27 cells co-transfected with wild-type CTC-338M12.4 sequence and miR-27a-5p sequence was lower than that of CAL-27 cells co-transfected with wild-type CTC-338M12.4 sequence and miR-27a-5p irrelevant sequence, and the difference was statistically significant ( P < 0.001). The relative expression level of transcriptional level miR-27a-5p of CAL-27 cells in the CTC-338M12.4 group was lower than that in the control group, and the difference was statistically significant ( P = 0.003). Western blot showed that the protein expression levels of JAK/STAT signaling pathway p-JAK, p-STAT, p-Raf, p-ERK, and p-mTOR were lower than those in the control group. Conclusions:The level of lncRNA CTC-338M12.4 is low in tongue squamous cell carcinoma. CTC-338M12.4 mediates the inactivation of JAK/STAT signaling pathway via inhibiting miR-27a-5p expression in tongue squamous cell carcinoma CAL-27 cells, thereby leading to cell cycle arrest and inhibiting the cell proliferation and migration of CAL-27 cells.
