Objective:A novel grass-root community screening and management model of hepatitis B was developed in order to improve the diagnosis and treatment rate of hepatitis B in Guangzhou city.Methods:A three-tier collaborative framework［tertiary hospitals-center for disease control and prevention（CDC）-primary care clinics］implemented dual-track screening（fixed-site+mobile units）using rapid hepatitis B surface antigen（HBsAg）testing and structured surveys. Digital closed-loop management integrated screening，referral，and follow-up. Data were analyzed via SPSS 26.0.Results:Among 30 012 community-dwelling adults screened（Male∶Female=1∶1.68），overall HBsAg positive rate was 5.21%（1 565/30 012），peaking in the 50-59-year cohort（ χ2=271.80， P<0.001）. Hepatitis B knowledge awareness was critically low（39.24%）. Of 140 referred HBsAg-positive individuals，15 chronic carriers required no immediate antiviral therapy per guidelines. Treatment linkage surged from 32.8%（41/125）to 86.4%（108/125）post-intervention. aMAP hepatocellular carcinoma（HCC）risk stratification（n=82）revealed low（36.6%），intermediate（32.9%），and high-risk（30.5%）profiles. Conclusions:This coordinated，digitally-enhanced strategy significantly improved hepatitis B detection and treatment access. However，persistent knowledge gaps underscore the imperative for targeted community education and adherence support.

Eyelid tumor is a serious eye disease that leads to vision loss or even blindness.The similarity between benign and malignant characteristics makes it difficult for ophthalmologists lacking clinical experience to distinguish between them.To address the problem,a method(ResNet101_CBAM)based on two-stage target localization using fully convolutional one-stage object detection(FCOS)and residual network incorporating a dual attention mechanism is proposed to realize the automatic diagnosis of benign and malignant eyelid tumors.FCOS is used to automatically localize the overall contour of the orbit,removing the background and surrounding noise,and then finely localize the tumor lesion inside the orbit.The obtained lesion region is input into ResNet101_CBAM for the automatic diagnosis of benign and malignant eyelid tumors.The experimental results show that the average precision of the target localization algorithm for tumor lesion is 0.821,and that compared with ResNet101,ResNet101_CBAM improves the sensitivity and accuracy in eyelid tumor classification by 4.7%and 3.0%,respectively,indicating that the proposed model has superior performances in the automatic diagnosis of benign and malignant eyelid tumors.

BACKGROUND: Acquired and primary resistance to epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is still the bottleneck of clinical treatment of advanced non-small cell lung cancer (NSCLC). STE029 is a novel anticancer drug which consists of 3-hydroxy-3-methylglutarylcoenzyme A reductase (HMGCR) inhibitor and novel cancer cell membrane targeting molecular. This study aimed to investigate the reversal mechanism of EGFR-TKI resistance by STE029 in lung adenocarcinoma. METHODS: CCK8 test was used to test the cell viability and survival rate of EGFR mutated PC9 cell (Gefitinib sensitive), PC9/BB4 cell (acquired Gefitinib resistant), and EGFR wild type A549 cell after treatment of STE029, Gefitinib or combination of both. EdU test was applied to detect changes in cell cycle and Hoechst 33258 was applied to detect apoptosis rate in overcoming the EGFR-TKI resistance. The activity of EGFR/PI3K/Akt, cell cycle and apoptosis signal pathways were examined. In vivo, nude mice were exposed to STE029, Gefitinib and STE029+Gefitinib for 5 wk. And the the tumor volume was measured and tumor weight was obtained on the last day. RESULTS: (1) PC9 cells was highly sensitive to Gefitinib, while PC9/BB4 and A549 cell showed significant resistance to Gefitinib treatment; (2) STE029+Gefitinib treatment could significantly decrease the 50% inhibitory concentrarion (IC₅₀) of Gefitinib in PC9, PC9/BB4 and A549 cells (P<0.05, respectively); (3) In PC9 and PC9/BB4 cells, STE029+Gefitinib can block cell cycle and inhibit cell proliferation (P<0.001), while there was no significant difference in apoptosis rate among three drug intervention groups (P>0.05); However, apoptosis rate was increased in STE029+Gefitinib group in A549 cell (P<0.01), while no significance detected in cell proliferation (P>0.05). (4) In PC9 and PC9/BB4 cells, the combination of STE029 and Gefitinib could downregulate p-EGFR, p-Akt, p-Cyclin D1 and Cyclin D1 (P<0.001), and upregulate the expression of GSK-3β (P<0.001), and the expression of cleaved caspase-8, caspase-8 cleaved caspase-9, caspase-9 showed no difference among groups (P>0.05). In A549 cells, the combination of STE029 and Gefitinib could downregulate p-Akt (P<0.001) and upregulate cleaved caspase-8 and cleaved caspase-9 (P<0.001); (5)In vivo, the combination of STE029 and Gefitinib effectively inhibited tumor development and progression compared to STE029 alone or Gefitinib alone, with significant difference (P<0.05) in PC9 and PC9/BB4 xenografted tumor. CONCLUSIONS STE029 could sensitize Gefitinib by inhibiting EGFR/PI3K/Akt pathway, blocking the tumor cell cycle and proliferation and inducing apoptosis through caspase-8 and caspase-9 dependent pathway. STE029 deserves further investigations in overcoming EGFR-TKI resistance in lung cancer.

Objective To investigate the predictive role of the intraoperative amylase ( IOA ) from pancreatic stump for postoperative pancreatic fistula. Methods The clinical data of 26 patients who received distal pancreatectomy ( DP) and central pancreatectomy ( CP) in the Shanghai Ruijin Hospital from June 2017 to July 2018 were retrospectively analyzed. IOA and peri-operative potential clinical factors associated with pancreatic fistula were analyzed. Receiver operating characteristics ( ROC) curve was drawn to evaluate the diagnostic efficacy of IOA from pancreatic stump in predicting postoperative pancreatic fistula, and the sensitivity and specificity were calculated. Results Of 26 patients, 19 patients underwent DP and 7 patients underwent CP. 9 patients (34.6％,9/26)had class A pancreatic fistula (biochemical leak) and 11 patients (42. 3％,11/26) had class B pancreatic fistula after surgery, and no class C pancreatic fistula occurred. Univariate analysis showed that IOA from pancreatic stump in clinically relevant pancreatic fistula group was higher than that in clinically irrelevant pancreatic fistula group(7971. 82 ± 4387. 98 vs 1589. 20 ± 1405. 00, P=0. 001). Area under the curve ( AUC) of IOA in predicting the development of clinically relevant pancreatic fistula after surgery was 0. 921 and 95％ confidential interval was 0. 807-1. 000. The optimal cut-off value was 3622 U/L , and the sensitivity and specificity were 90. 9％ and 86. 7％. Conclusions IOA from pancreatic stump could serve as a clinical indicator for predicting the occurrence of postoperative pancreatic fistula.

OBJECTIVE: To investigate the effect of 1,2-dichloroethane(1,2-DCE) acute inhalation exposure on the differential gene expression of phase Ⅰ metabolic enzymes. METHODS: The specific pathogen free SD rats were randomly divided into control group(16 rats), low-and high-dose groups(24 rats in each group, half males and half females). Low-and high-dose group were given daily 600, 1 800 mg/m~(3 ) of 1,2-DCE, and the control group given the fresh air by dynamic inhalation for 8 hours per day for consecutive 7 days. After the end of exposure, the relative mRNA expression of cytochrome P450 2 E1(CYP2 E1), alcohol dehydrogenase(ADH1) and acetaldehyde dehydrogenase 3 alpha 1(ALDH3α1) in the liver tissue was detected by real-time fluorescence quantitative polymerase chain reaction. RESULTS: The relative expression of CYP2 E1 in male high-dose group was higher than that in male low-dose group and female high-dose group(P<0.05). The relative expression of ADH1 in male low-and high-dose groups was higher than that in male control group(P<0.05). The relative expression of ADH1 in male high-dose group was higher than that in male low-dose group and female high-dose group(P<0.05). The relative expression of ALDH3α1 in high-dose group was higher than that in control group and low-dose group(P<0.05). CONCLUSION: High dose 1,2-DCE could increase the gene expression of phase Ⅰ metabolic enzymes in rat liver. The 1,2-DCE has more obvious effect in male rats than in female rats.
