Objective To investigate the effects of FOXA2 on the proliferation of hepatocellular carcinoma cells and the tumorigenesis of nude mice, and to explore the effect of FOXA2 on the development of hepatocellular carcinoma. Methods Immunohistochemistiy and real-time quantitative PCR were used to detect the expression of FOXA2 in 35 pairs of hepatocellular carcinoma tissues and their matched paracancerous tissues. 293 T cells were used as controls to detect the expression level of FOX A 2 in hepatocellular carcinoma cell lines (HepG2, SMMC-7721 and SK-Hep1) by real-time quantitative PCR. The lentivirus was transfected into HepG2 cells, and there were 3 groups including no virus group (Mock group) , negative control virus group (NC group) and FOXA2-transfected over-expression virus group (FOXA2 group). Plate clone assays were used to detect the effect of FOXA2 on the proliferation of HepG2 cells in vitro and nude mice tumor and formation assays to detect the tumor weight and tumor weight inhibition rate after FOX A2-transfected overexpression of lentivirus-infected cells. Results The results of immunohistochemistry and real-time quantitative PCR showed that the expression of FOXA2 in cancer tissues was significantly lower than that in adjacent tissues (P < 0.01) , And the expression of FOXA2 in hepatoma cell lines (HepG2, SMMC-7721, SK-Hepl) was significantly lower than that of 293 T cells (P < 0.0001). After the lentivirus was transfected into HepG2 cells, the number of clones in the FOXA2 group was significantly less than that in the Mock group and the NC group (P < 0.05). The tumor formation of nude mice showed that the tumor weight of FOXA2 group was smaller than that of the corresponding blank control group and negative control group (P < 0.01).Conclusion FOXA2 is lowly expressed in hepatocellular carcinoma tissues and cells, which has the effect of inhibiting the proliferation of HepG2 cells in vitro and the growth of tumors in nude mice in vivo.

Objective:To investigate the expression of hsa_circ_0019413 in the peripheral blood of patients with primary Sj?gren's syndrome (pSS) and its role in the development of pSS disease.Methods:Microarray screening of circ ribonucleic acid (circRNA) changes was first performed in the peripheral blood of 4 pSS patients and 4 healthy controls. Real-time quantitative reverse transcription polymerase chain reaction (qPCR) was used to verify the difference in the expression of hsa_circ_0019413 in the peripheral blood of 30 pSS patients and 30 controls. By establishing the receiver operating characteristic (ROC) curve, the potential diagnostic value of hsa_circ_0019413 in peripheral blood was analyzed, and the expression level of hsa_circ_0019413 was correlated with the clinical presentations of patients with pSS.Results:① By microarray analysis, 437 circRNAs were differentially expressed between the two groups (FC≥2.0, P<0.05), of which 365 were up-regulated and 72 were down-regulated. ② The expression level of hsa_circ_0019413 in pSS patients was significantly higher than that in healthy controls by qPCR. The difference between the two groups was statistically significant ( P<0.05). It showed that hsa_circ_0019413 in peripheral blood of pSS patients had potential diagnostic value by ROC curve analysis [area under the curve (AUC)=0.883, 95% CI (0.782, 0.984), P<0.01]. ③ The expression level of hsa_circ_0019413 was positively correlated with the ESSDAI, ANA, titer of the pSS patients by correlation analysis ( r=0.721, P=0.012; r=0.625, P=0.040), but not with (immunoglobulin (Ig)G or erythrocyte sedimentation rate (ESR). Conclusion:Hsa_circ_0019413 in the peripheral blood may be involved in the development of pSS and may be a biomarker for the diagnosis of pSS.

Objective:To investigate the clinical features and risk factors of multiple organ dysfunction syndrome (MODS) caused by wasp sting.Methods:A retrospective cohort study was conducted to collect the general data of wasp sting patients who had a clear history of wasp sting disease and clinical manifestations from June 2016 to December 2020 and were first diagnosed as wasp sting in hospital. Patients with hematological diseases, malignant tumors, severe liver and kidney dysfunction, cardiac insufficiency, and patients who had received hormone therapy before admission were excluded. Patients who were unable to obtain effective laboratory results due to hemolysis or other reasons within 48 h of admission were also excluded. The white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), hemoglobin count (HB), myoglobin (Mb/MYO), activated partial thromboplastin time (APTT), albumin (ALB), K, Na, and Cl of the blood samples collected within 48 h after admission were recorded. Patients were divided into the MODS group and non-MODS group according to whether MODS occurred during hospitalization. Uni- and multivariate analysis were used to analyze the factors affecting the occurrence of MODS in wasp sting patients during hospitalization, and the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive effect of myoglobin level on the occurrence of MODS in wasp sting patients during hospitalization.Results:Mb, WBC, NEU, APTT and serum potassium in the MODS group [3890.00 (1416.90-4057.00) ng/mL, (21.99 ± 8.18) × 10 9/L, (19.61 ± 7.33)× 10 9/L, (93.75 ± 45.77) s, and (4.99 ± 0.95) mmol/L] were significantly higher than those in the non-MODS group [73.50 (34.30-264.20) ng/mL, (13.40 ± 4.14)× 10 9/L, (11.18±4.73)× 10 9/L, (37.00 ± 17.16) s, and (4.05 ± 0.56) mmol/L] (all P < 0.05); blood chlorine and ALB [(101.50 (98.25-105.00) mmol/L and (35.36 ± 6.44) g/L)] were significantly lower than those in the non-MODS group [(105.00 (103.00-107.00) mmol/L and (40.71 ± 5.48) g/L)] (all P < 0.05). Multivariate logistic regression analysis showed that NEU ( OR = 0.729, 95% CI: 0.542~0.981), Mb ( OR = 0.999, 95% CI: 0.998~1.000), and APTT ( OR = 0.951, 95% CI: 0.921~0.982) were independent risk factors for MODS in wasp sting patients. ROC curve analysis showed that NEU, Mb and APTT could be used to evaluate the occurrence of MODS in wasp sting patients. Among them, Mb had the highest predictive value (AUC = 0.950, 95 % CI: 0.891~0.982). The optimal cutoff value of Mb for predicting the occurrence of MODS in wasp sting patients was 515.30 ng/mL, and the corresponding sensitivity and specificity were 90.62% and 87.23%, respectively. Conclusion:Mb is an independent risk factor for MODS in wasp sting patients, which can be used as a good predictor of MODS in wasp sting patients.

Objective:To investigate the safety and dose of 4D template (real-time adjustable angle template) in the treatment of advanced malignant tumors with 125I seeds. Methods:98 patients with advanced malignant tumors admitted to Department of Thoracic Surgery of Shaanxi Provincial Tumor Hospital were treated with 4D template-navigated radioactive 125I seed implantation from June 2018 to December 2019. Preoperative TPS plan, intraoperative optimization, postoperative verification of immediate dose and postoperative evaluation of implantation dose were performed. The treatment results were observed. Results:All 98 patients completed the seed implantation. The implantation dose of GTV of implantation site receiving external irradiation was (12 489±414) cGy and the dose of no external irradiation was (15 036±514) cGy. V 100% was 84.7%-94.1%, and 88.2%-93.7%. The implantation dose of CTV was (7 450±621) cGy, and (9 080±761) cGy. The quality of dose implantation was evaluated as: excellent in 89 cases (91%, 89/98), good in 7 cases (7%, 7/98), fair in 2 cases (2%, 2/98), and poor in 0 case, respectively. The symptom relief rate of patients with pain was 92%(36/39). The 1-and 2-year local control rates were 61%, 36% and 82%, 54% in patients treated with and without external irradiation, respectively. The difference was statistically significant ( P=0.02). The incidence rates of pneumothorax and hemoptysis were 19%(9/48) and 10%(5/48). No corresponding complications were observed in other parts of the patients. Conclusion:4D template-assisted 125I seed therapy is safe and effective for malignant tumors, and intraoperative adjustment of needle angle and dose optimization can realize the precise control of implantation dose.

Acute idiopathic maculopathy(AIM)is an inflammatory lesion of unknown cause that primarily affects the macula. It follows a unique natural course, distinct from other maculopathy, often manifesting as a sudden loss of visual acuity followed by flu-like symptoms that gradually resolve as the disease subsides. A comprehensive understanding of the unique history, multimodal imaging, and a thorough systematic examination are crucial in determining the final diagnosis of AIM. The treatment and prognosis of AIM remain controversial. Meanwhile, it presents similar clinical manifestations and pathological changes to various chorioretinopathy, posing challenges for clinical differentiation. This article provides a review of its pathogenesis, clinical symptoms, multimodal imaging features, diagnosis and differential diagnosis, treatment and prognosis, in order to reduce misdiagnosis and mistreatment while enhancing comprehension of AIM.
