Objective To compare the long-term survival outcomes of patients with T_1-2N₀M₀ duodenal neuroendocrine tumor (DNET) after endoscopic resection (ER) or surgical resection (SR). Methods Patients diagnosed with T_1-2N₀M₀ DNET between January 1, 2004, and December 31, 2015, were extracted from the SEER database. Kaplan-Meier survival curve and log-rank test were used to compare overall survival (OS) rate and cancer-specific survival (CSS) rate between patients undergoing ER or SR. Propensity score matching (PSM) was used to reduce grouping differences, and multivariate Cox regression was used to analyze factors affecting OS and CSS before and after PSM. Results A total of 656 patients were included, with 457 in ER group and 199 in SR group. Before PSM, there was no significant difference in the 5-year OS rate between the ER and SR groups (88.9% vs 89.6%), but there was a significant difference in the 5-year CSS rate (99.3% vs 96.9%, P＝0.017). Before PSM, multivariate Cox regression analysis showed advanced age was an independent risk factor for decreased OS (P＜0.001). After PSM, there was no significant difference between the ER group (n＝187) and SR group (n＝187) in 5-year OS rate (90.2% vs 88.9%) or CSS rate (98.9% vs 96.7%). After PSM, multivariate Cox regression also showed advanced age was an independent risk factor for decreased OS, while resection method was not an independent factor for OS or CSS. Conclusions There is no significant difference in OS or CSS after endoscopic treatment and surgical treatments for patients with T_1-2N₀M₀ DNET, and advanced age is an independent factor for OS.

Human physiological indicators have become an important standard for assessing health in modern society.Traditional detection methods often require a separate laboratory,complex operation process and long detection time,so it is urgent to develop portable,fast and accurate on-site detection technologies for bioanalysis.Point-of-care testing(POCT),which differs from traditional laboratory testing,can realize the rapid in situ detection of biomarkers without the complicated analytical process of the laboratory.Smartphones,which are an essential tool in our daily life,not only have independent operating systems and built-in storage functions,but also have high-definition cameras,which have great application potential in POCT visualization.The combination of various biosensing technologies and smartphones has developed into a new direction in the field of POCT.This review mainly introduced the research progress of smartphone-based visual biosensors in POCT in recent years,including colorimetric sensors,fluorescence sensors,chemiluminescence sensors and electrochemiluminescence sensors.Finally,the problems faced by smart-phone-based visual biosensors in the application of POCT were summarized,and their future development was prospected.

Objective To provide pharmaceutical monitoring using the Pharmaceutical Care Network Europe(PCNE)for patients with respiratory diseases,to explore effective pharmaceutical monitoring models in the department of respiratory,and to promote clinical rational drug use.Methods Inpatients diagnosed with chronic obstructive pulmonary disease(COPD)and lung infections in 2022 at the First Affiliated Hospital of Anhui University of Science and Technology were selected and divided into a simple group and an intervention group.According to the PCNE classification system,the types,causes,interventions,acceptance of interventions,and resolution status of drug-related problems(DRPs)were analyzed.Results A total of 120 cases were included,60 cases in the simple group and 60 cases in the intervention group.Regarding the number of DRPs,there were 15 cases in the simple group and 45 cases in the intervention group,and there was a significant difference between the two groups(P<0.05).There were a total of 82 DRPs,which were mainly related to therapeutic efficacy(51.22%)and safety(46.34%),and the reasons for this were that patients'incorrect medication usage method,inappropriate usage and dosage,and unscheduled safety monitoring,etc.The pharmacist interventions were 75(91.46%)at the drug level,38(46.34%)at the physician level,and 43(52.44%)at the patient level;after the pharmacist interventions,the acceptance rate was in the range of 97.56%,and 74.39%of the DRPs were resolved.Conclusion PCNE classification system helps clinical pharmacists to enhance their ability to find and deal with DRPs,reduce the risk of clinical adverse events and promote reasonable and safe drug use.Meanwhile,it is conducive to the standardization of pharmaceutical care records for patients with respiratory diseases and provides reference for pharmaceutical service models for patients in the department of respiratory.

Pregnancy is a special period for developing and treating oral diseases.Oral emergencies during pregnancy need to be handled appropriately.Changes in the physiological environments and personal habits of pregnant women in-crease susceptibility to some oral diseases.However,clinical treatment strategies are limited due to the need to ensure the safety of pregnant women and fetuses.Pregnant women should obtain oral health knowledge and enhance their aware-ness.Dentists should adhere to the principle of"prevention before pregnancy,controlling symptoms during pregnancy,and treating diseases after pregnancy"for different pregnancy periods.They should also formulate appropriate treatment plans to control emergencies,prevent disease progression,and avoid harmful effects on pregnant women by using the saf-est,simplest,and most effective strategies that avoid adverse effects on fetuses.Pregnant women and dentists should combine prevention and treatment while collaborating in maintaining oral health during pregnancy.This article focuses on the principles of treatment during pregnancy,and the treatment timing,clinical management,and treatment strategies of different diseases causing oral emergencies during pregnancy are reviewed.

Objective:To study the effects of different doses of X-ray irradiation on the immune microenvironment and cGAS-STING signaling pathway of hepatocellular carcinoma cells.Methods:C57BL/C mice were subcutaneously injected with Hepa 1-6 hepatocellular carcinoma cells in the right axilla to establish a subcutaneous tumor-forming hepatocellular carcinoma model. The mice were randomly divided into 0, 4, 8, 12 Gy irradiation groups, with 10 mice in each group. The body weights and tumor volumes were monitored. Specimens were collected 28 d after irradiation. The ELLSA and Flow Cytometry method was used to compare the macrophage-associated cytokines tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-6 (IL-6), chemokine ligand 5 (CCL5), IL-10, IL-13, transforming growth factor-β (TGF-β), IL-4 and macrophage M1, M2 phenotype ratio (M1/M2). Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and immunoblotting assay were used to detect the expression of genes and proteins related to the cGAS-STING signaling pathway in hepatoma cells.Results:With the increase of irradiation dose, the tumor volume was significantly reduced ( F=8.42, P<0.05), the proportion of cell necrosis increased ( F=3.89, P<0.05), the content of macrophage-associated cytokines other than IL-4 increased ( F=6.32-15.50, P<0.05), and the proportion of M1 and M2 types of macrophage in the immune microenvironment of hepatocellular carcinoma tumors was elevated ( F= 5.46, 5.14, P < 0.05).The gene expression and protein expression levels of cGAS-STING signaling pathway were elevated in hepatocellular carcinoma cells (mRNA expression of cGAS and STING: F=6.35, 16.10, P<0.05; protein expression of cGAS and STING: F=71.31, 37.15, P<0.05). Conclusions:X-ray irradiation activates the cGAS-STING signaling pathway in hepatocellular carcinoma cells and contributes to the remodeling of the tumor immune microenvironment.

In this study,nine hybridoma cells secreting monoclonal antibodies against deltamethrin were prepared,and the monoclonal antibody 4D4E11 with best sensitivity was selected to develop indirect enzyme-linked immunosorbent assay (ic-ELISA) and gold nanoparticle-based lateral flow immunoassay (LFIA) for detection of deltamethrin. The optimal working buffer for ic-ELISA was 0.01 mol/L phosphate buffer (pH 7.4) containing 0.2 mol/L NaCl and 20％ methanol,while 0.01 mol/L phosphate buffer (pH 7.4) containing 1 mol/L NaCl,5‰Tween-20 and 10％methanol for LFIA. Under the optimal conditions,the half inhibition concentration (IC50) and limit of detection (IC10) of ic-ELISA were 10.60 ng/mL and 1.43 ng/mL respectively,and the limit of detection of the developed LFIA was 0.5μg/mL. The developed ic-ELISA and LFIA showed no cross-reactivities (CRs) with eight kinds of analogues of deltamethrin,which indicated the excellent specificity of proposed immunoassays. The average recoveries of the ic-ELISA in spiked tomato,cabbage and lettuce samples were 79.8％-92.6％with relative standard deviations of 0.8％-5.5％. The detection results of LFIA were consistent with the spiked concentrations in the range of 1-5 mg/kg. Meanwhile,the results of ic-ELISA and LFIA showed close correlation with high performance liquid chromatography (HPLC) in the test of blind lettuce samples. The experimental results demonstrated that the two immunoassays proposed here were suitable for rapid detection of deltamethrin with high sensitivity and high accuracy.

Objective To observe the curative effect of comprehensive traditional Chinese medicine(TCM)therapy for the treatment of refractory sudden hearing loss(i.e.,suffering sudden hearing loss more than 2 weeks),and to analyze the factors that may affect the prognosis.Methods A retrospective analysis was carried out in 405 hospitalized patients with refractory sudden hearing loss who were treated in the Department of Otorhinolaryngology,the First Affiliated Hospital of Guangzhou University of Chinese Medicine from 2005 to 2022.The patients were all treated by comprehensive TCM therapy including oral administration of Chinese medicine,acupuncture,acupoint seed-pressing application after individualized syndrome differentiation.The overall clinical efficacy was evaluated,and the difference of efficacy in the patients with various courses of disease,degrees of deafness,types of hearing curve,concomitant symptoms and TCM syndrome types,having or not having previous treatment history was analyzed.Results For the 405 patients with refractory sudden hearing loss,the cure rate was 5.7％and the total effective rate was 28.1％.Among the 405 patients,the best efficacy was achieved in the patients with mild hearing loss,low-frequency decline type of hearing curve,and having no previous treatment history,and the differences were statistically significant(P＜0.05 or P＜0.01).There was no significant difference in the efficacy of patients with different courses of disease,with or without concomitant symptoms,or with various syndrome types(P＞0.05).Conclusion The comprehensive TCM therapy has a certain effect on refractory sudden hearing loss.Patients with poor efficacy after conventional western medicine can still benefit from the comprehensive TCM therapy.
