ObjectiveTo establish a tumor prognostic risk assessment model related to target genes of the miR-34 family. MethodsTarget genes of the miR-34 family were screened, and the scores of miR-34 target genes were assessed in 16 tumor types. Univariate Cox regression analysis was used to identify the tumor type with the strongest correlation between miR-34 target gene scores and overall survival (OS). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to elucidate the functional roles and signaling pathways of miR-34 target genes. A prognostic risk model based on the miR-34 target genes was constructed using univariate Cox and LASSO regression analyses. Quantitative real-time PCR (qPCR) and dual-luciferase reporter assays were conducted to validate whether the target genes bind to miR-34 and measure their RNA expression levels in the relevant tumors. Additionally, the risk score was integrated with other clinical indicators to develop a nomogram prediction model for patient survival. ResultsA total of 65 target genes of the miR-34 family were screened. The cancer type exhibiting stronger correlation between the target gene scores and OS was lung adenocarcinoma (P = 0.003, HR= 5.150). Furthermore, miR-34 target genes were predominantly enriched in oxidative stress pathways and various tumor-related processes. Three genes, LDHA, GALNT7, and SATB2, were identified as core components of the prognostic analysis model for lung adenocarcinoma. Additionally, the constructed nomogram model demonstrated robust predictive performance. ConclusionThe risk model and prognosis model of lung adenocarcinoma constructed based on the key target genes of miR-34 have good predictive performance.

Objective To analyze the levels of serum CTCs and ctDNA in NSCLC patients receiving first-line EGFR-TKI treatment, and to explore the clinical value of CTCs and ctDNA detection in assessing the efficacy of treatment for advanced lung cancer. Methods A total of 109 NSCLC patients receiving first-line EGFR-TKI treatment were enrolled. Serum tumor markers CEA, CTCs, and ctDNA were detected at baseline and after one month of treatment. Chest CT scans were performed, and treatment efficacy was evaluated based on RECIST1.1 criteria. CTCs were counted by enrichment-staining-computational algorithm to analyze malignant features, while ctDNA was assessed using digital PCR. Results Survival rate was low in patients with abnormal CEA and ctDNA tests at baseline and in patients with reduced serum CTCs after treatment. In the SD subgroup of patients with brain metastases and advanced stage, the PFS benefit was low. Conclusion Patients in the SD subgroup have significantly higher recurrence risks than those in the PR or CR subgroups. Therefore, CTC and ctDNA testing should be applied to patients in the SD subgroup to identify high-risk patients with poor response to EGFR-TKI treatment, intervene with additional treatment promptly, and obtain long progression-free survival.

Objective:
To investigate the mechanism of miR-224-5p on proliferation, apoptosis, invasion and migration of human hepatocellular carcinoma HepG2 cells.
Methods :
The RNA expression levels of miR-224-5p and early growth responsive gene 2(EGR2) in patients with hepatocellular carcinoma were obtained from the TCGA dataset. Normal human hepatocytes LO2 and hepatoma cells HepG2 were cultured in vitro, and the HepG2 cells were transfected with lentiviral vectors(knockdown of miR-224-5p), small interfering RNA fragments or overexpression vectors(interference and overexpression of EGR2). The expression levels of miR-224-5p and EGR2 in hepatocellular carcinoma cDNA chips and cells were detected by quantitative real-time PCR(qPCR). The expression level of EGR2 protein was detected by Western blot. Dual luciferase reporter gene assay was used to detect the binding of miR-224-5p to EGR2. HepG2 cells positive rate were detected by EdU assay, apoptosis rate was detected by flow cytometry, cell invasion number was detected by Transwell assay, and cell mobility was detected by scratch assay.
Results :
Compared with paracancerous tissues, the expression of miR-224-5p was increased and the expression of EGR2 mRNA decreased in HCC tissues. Compared with LO2 group, the expression of miR-224-5p in HepG2 cells increased, and the expression of EGR2 mRNA and protein decreased. Compared with the Lv-sh-NC group, the 24 h EdU positive cell rate, cell invasion number, and 48 h cell mobility of HepG2 cells in the Lv-sh-miR-224-5p group decreased, while the apoptosis rate increased. Compared with Oe-NC group, 24 h EdU positive cell rate, cell invasion number, and 48 h cell mobility of HepG2 cells in Oe-EGR2 group decreased, while apoptosis rate increased. Compared with Lv-sh-NC group, the expression of EGR2 protein in Lv-sh-miR-224-5p group increased. Compared with Lv-sh-miR-224-5p+si-NC group, 24 h EdU positive cell rate, cell invasion rate, and 48 h cell mobility of HepG2 cells in Lv-sh-miR-224-5p+si-EGR2 group increased, while apoptosis number decreased.
Conclusion
miR-224-5p can promote proliferation, invasion, and migration of HepG2 cells and inhibit apoptosis via binding with EGR2.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:
To investigate the current status of milk tea consumption and its association with psychological distress among college students, so as to provide theoretial support for promoting the mental health of college students.
Methods:
From September to November 2023, a convenience sampling method was used to select 15 440 college students aged 17-24 from seven universities in Shanghai, Jiangxi, Hubei, and Shanxi. A self designed questionnaire and the Kessler Psychological Distress Scale were used to assess milk tea consumption and psychological distress, respectively. The Mantel-Haenszel test was employed to analyze the trend of psychological distress at different levels of milk tea consumption. Binary Logistic regression analysis was used to determine the association between milk tea consumption and psychological distress, and the restricted cubic spline method was applied to explore the nonlinear relationship between milk tea consumption and symptoms of psychological distress.
Results:
The detection rate of psychological distress among college students was 59.6%. Univariate analysis indicated a significant trend association between milk tea consumption frequency ( χ 2 trend =42.33) and milk tea intake level ( χ 2 trend = 5.17 ) with psychological distress ( P <0.05). Binary Logistic regression models showed a positive association between different levels of milk tea consumption frequency and psychological distress [1-3 times (mild to moderate distress, OR =1.20,1.41), 4-5 times (mild to severe distress, OR =2.80,5.44,4.12), and ≥6 times (severe distress, OR =8.04); and milk tea intake level: 1-1 500 mL (severe distress, OR =1.35), >1 500- <3 000 mL (mild to moderate distress, OR =1.21, 1.35), ≥3 000 mL (mild to severe distress, OR =1.33,1.71,1.29)] ( P <0.05 ). The restricted cubic spline model showed a nonlinear association between milk tea intake and the risk of psychological distress ( F = 107.34 , P non linear <0.01, P overall <0.01).
Conclusions
High frequency and high volume milk tea consumption are associated with an increased risk of psychological distress among college students. Reducing the consumption behavior of college students milk tea is helpful to improve mental health.
