ObjectiveTo investigate the difference in the risk of cardiovascular diseases between patients with different subtypes of non-alcoholic fatty liver disease （NAFLD） from the perspective of metabolism， since cardiovascular events induced by metabolic disorders are the leading cause of death in NAFLD. MethodsThe cluster sampling method was used to conduct a multicenter cross-sectional study among three representative hospitals in Pudong New Area of Shanghai， China. A total of 37 122 sets of physical examination data from July 2022 to June 2023 were collected and stratified according to body mass index （BMI）. The chi-square test was used for comparison of continuous data between groups， and a multivariable Logistic regression analysis was used to investigate the association between NAFLD subtypes and cardiometabolic risk factors. ResultsA total of 9 372 cases of NAFLD were detected， with a detection rate of 25.25%， and more than 97% of these patients were diagnosed with metabolic associated fatty liver disease （MAFLD）. The subgroup analysis showed that the detection rates of lean， overweight， and obese NAFLD were 7.72%， 33.99%， and 63.56%， respectively. Compared with the patients with lean or overweight NAFLD， the patients with obese NAFLD showed a significantly higher proportion of patients with abnormalities in blood pressure， blood glucose， triglyceride （TG）， high-density lipoprotein （HDL） or uric acid （all P<0.001）. Among related risk factors， lean NAFLD was associated with the increase in total cholesterol （TC）（P<0.05）， while overweight NAFLD and obese NAFLD were not associated with TC abnormalities （P>0.05）； obese NAFLD was not associated with TG abnormalities， while lean NAFLD and overweight NAFLD were associated with TG abnormalities （both P<0.05）； all types of NAFLD were associated with the abnormalities of waist-hip ratio， blood pressure， blood glucose， low-density lipoprotein， HDL， and uric acid （all P<0.05）. ConclusionThe detection rates of different subtypes of NAFLD in Shanghai Pudong are close to those reported in China and globally， and the epidemiologic data of NAFLD can be used analogously for MAFLD. There are certain differences in the distribution and association of cardiometabolic risk factors between different subtypes of NAFLD， and targeted interventions should be formulated based on the metabolic characteristics of each type of NAFLD.

Objective To compare the clinical application value of medical glue and a new-type medical anchor positioning needle in thoracoscopic resection of pulmonary nodules.Methods A total of 182 patients with pulmonary nodules,who received video-assisted thoracic surgery(VATS)at the Department of Thoracic Surgery of Affiliated Hospital of Shaoxing University of China between January 2020 and December 2022,were enrolled in this study.Preoperative CT-guided localization of the pulmonary nodule was performed in all patients,including medical glue positioning in 89 patients(medical glue group)and anchor needle positioning in 93 patients(anchor needle group).The incidences of pneumothorax and bleeding,the time spent for positioning,the interval between localization and operation,the time spent for operation,and the radiation dose during localization process were recorded and the data were statistically analyzed.Results The success rate of positioning was 100％(93/93)in the anchor needle group and 96.7％(86/89)in the medical glue group.There was no statistically significant difference between the two groups(P>0.05).The incidence of bleeding was 31.2％(29/93)in the anchor needle group and 15.7％(14/89)in the medical glue group,and the difference between the two groups was statistically significant(P<0.05).The incidence of pneumothorax was 30.1％(28/93)in the anchor needle group and 20.2％(18/89)in the medical glue group,and there was no significant difference between the two groups(P>0.05).No statistically significant difference in the time spent for operation existed between the two groups(P>0.05).The time spent for positioning and the interval between localization and operation in the medical glue group were longer than those in the anchor needle group,and the radiation dose in the medical glue group was higher than that in the anchor needle group,and the differences between the two groups were statistically significant(P<0.05).Conclusion For the preoperative localization of ground glass opacity(GGO)or solitary pulmonary nodule(SPN),both medical glue positioning method and anchor needle positioning method have high clinical application value.The clinical and interventional physicians should adopt appropriate positioning method according to the patient's condition.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Hypoxia, as an important hallmark of the tumor microenvironment, is a major cause of oxidative stress and plays a central role in various malignant tumors, including glioblastoma. Elevated reactive oxygen species (ROS) in a hypoxic microenvironment promote glioblastoma progression; however, the underlying mechanism has not been clarified. Herein, we found that hypoxia promoted ROS production, and the proliferation, migration, and invasion of glioblastoma cells, while this promotion was restrained by ROS scavengers N-acetyl-L-cysteine (NAC) and diphenyleneiodonium chloride (DPI). Hypoxia-induced ROS activated hypoxia-inducible factor-1α (HIF-1α) signaling, which enhanced cell migration and invasion by epithelial-mesenchymal transition (EMT). Furthermore, the induction of serine protease inhibitor family E member 1 (SERPINE1) was ROS-dependent under hypoxia, and HIF-1α mediated SERPINE1 increase induced by ROS via binding to the SERPINE1 promoter region, thereby facilitating glioblastoma migration and invasion. Taken together, our data revealed that hypoxia-induced ROS reinforce the hypoxic adaptation of glioblastoma by driving the HIF-1α-SERPINE1 signaling pathway, and that targeting ROS may be a promising therapeutic strategy for glioblastoma.

Objective:To explore the impact of negation effect on color judgment of the color-word pairs and the impairment of cognitive inhibition function of the patients with schizophrenia (SCH) through embedding negation into the Stroop task.Methods:From January to December 2021, " Affirmative/ negative + color words" as the experimental materials, classical Stroop paradigm as the experimental paradigm, a mixed experimental design of 2 (groups: the SCH group vs the normal control group)×2(phrase polarity: affirmative phrases vs negative phrases)×2 (word-color congruence: consistency vs inconsistency) was designed to explore the inhibition function of negative phrases of the SCHs under bipolar negation conditions (Experiment 1) and multi-polar negation conditions (Experiment 2) respectively. The schizophrenic patients in Experiment 1(28 patients and 28 normal controls) and Experiment 2(30 patients and 30 normal controls) were sampled from the inpatients of Tangshan Kailuan Mental Health Center and Suzhou Guangji Hospital respectively, and the healthy controls were recruited from the community. SPSS 25.0 software was adopted as statistical analysis, and accuracy, response time of Stroop and the Stroop effect were analyzed by repeated measurement analysis of variance. Results:(1) The group main effects of response time were both significant in bipolar negation conditions(Experiment 1) ( F=49.22, P<0.001, ηp2=0.48) and multi-polar negation conditions (Experiment 2) ( F=37.58, P<0.001, ηp2=0.39). In bipolar negation (Experiment 1) conditions, as for the Stroop effect of response time, there was a significant interaction between the groups and polarities( F=4.42, P<0.05, ηp2=0.08), and there was a statistically significant difference between the affirmative Stroop effect (-0.137±0.522)and the negative Stroop effect(0.082±0.169) in the schizophrenia group( F=7.15, P<0.05, ηp2=0.12). In multi-polar negation conditions (Experiment 2), there was a marginal significant of the interaction between Stroop conditions and polarities in accuracy( F=3.81, P=0.056, ηp2=0.06). The accuracy under the word color consistency condition was higher than that under inconsistency condition((96.51±1.55)%, (90.00±2.54)%) ( F=5.15, P<0.05, ηp2=0.08). (3)In bipolar negation (Experiment 1) conditions, as for the accuracy, the interaction among groups, word color consistencies, and polarities was significant( F=6.66, P<0.05, ηp2=0.11). The interaction between word color consistencies and polarities was significant in the schizophrenia group( F=9.16, P<0.05, ηp2=0.15). In the normal group, the interaction between Stroop conditions and polarities was not significant( P>0.05). Conclusion:The impairment of cognitive inhibition function in schizophrenia is severe, which is reflected in negative processing; negation functions as cognitive inhibition, which is particularly prominent in bipolar negation.

Objective:Four cases with NLRP3-related autoinflammatory diseases were reported to summarize the clinical characteristics, genotype, and treatment responses of the disease, and to improve clinical pediatricians' understanding of the disease.Methods:A retrospective analysis was performed on 4 cases with NLRP3-related autoinflammatory diseases diagnosed in Children's Hospital of Anhui Province in 2016—2021, and the clinical features and treatment progress of NLRP3-related autoinflammatory diseases were retrospectively analyzed based on the clinical features, gene reports, and literature review.Results:① All 4 cases were male. Cases 1, 2, and 3 had the disease onset after birth, and case 4 had the disease onset 6 months after birth. All showed periodic fever, repeated urticaria-like rash, protruding forehead, and saddle nose. White blood cells count, erythrocyte sedimentation rate, and C-reactive protein were increased during the attack period, and those in the interval period were normal, and antibiotic treatment was ineffective. ② The genetic test of all these 4 children showed NLRP3 mutation. Children 1, 2, and 3 were heterozygous mutations, and their parents were wild-type. The mutation was located at chromosome Chr1: 247587658, exon c913 (exon3). G>A, the 305th aspartic acid (Asp) of the protein was changed to asparagine (Asn) in child 1. The mutation was located at the chromosomal Chr1: 247588072, the nucleic acid was changed to c1327(exon3)T>C, and the amino acid was changed to p.Y443H in cases 2 and 3. Somatic heterozygous mutation was found in case 4, and the child's parents were wild-type. In this case, the mutation was located at chromosomal Chr1: 247587658, exon3 G>A, and the 305th Asp of the protein was changed to Asn. ③Children in cases 1, 2, and 3 were treated with glucocorticoids and non-steroidal anti-inflammatory drugs at the initial stage, but the effects were limited. After receiving IL-1 antagonist treatment fever, skin rash, joint swelling and pain disappeared, and the inflammatory indexes were returned to normal. The child 4 received non-steroidal anti-inflammatory drugs and methotrexate, but he failed to respond to the treatment. Treatment with tocilizumab was not effective, however, fever, skin rash, or joint pain disappeared after treated with Khanna.Conclusion:①NLRP3-related autoinflammatory diseases can cause periodic fever, urticaria, joint involvement, and severe involvement of the central nervous system and organ amyloidosis. Which are early misdiagnosis is prone to systemic juvenile idiopathic arthritis. ②The disease was an inflammatory disease mediated by interleukin-1. At present, non-steroidal anti-inflammatory drug, glucocorticoid and chronic anti-rheumatic drugs have limited effects. IL-1 antagonists are effective and safe in the treatment of the disease.

Objective:To explore the relationship between the maximum standard uptake value (SUV max) based on 18F-fluorodeoxyglucose (FDG) PET-CT and the epidermal growth factor receptor (EGFR) mutation status of lung adenocarcinoma appearing as ground glass nodules (GGN). Methods:A total of 103 patients with lung adenocarcinoma from October 2011 to December 2020 in the Third Affiliated Hospital of Soochow University were retrospectively enrolled. All patients underwent 18F-FDG PET-CT and high-resolution CT, and underwent surgical resection and EGFR detecting within one month. The patients were divided into EGFR mutation group and wild group according to the EGFR test results. The GGN number, type, location, shape, lobulation sign, spicule sign, abnormal bronchial sign, vacuole sign, pleural indentation, diameter of GGNs (D GGN), diameter of solid component (D solid) and nodule ground-glass opacity component CT mean (CT GGO) were analyzed on CT images. The maximum standard uptake value (SUV max) of nodules was measured on PET-CT images. The t test, Mann-Whitney U test or χ 2 test were used to compare the differences of clinical data, pathological data, CT imaging parameters and SUV max between the two groups. Hierarchical binary logistic regression model was used to assess whether there was any association between SUV max and EGFR mutation status in different subgroups. Generalized additive model and smooth curve fitting were applied to solve nonlinear problems, and piecewise binary logistic regression model was used to explain nonlinearity. Results:A total of 103 patients with 106 nodules were finally included. There were 75 patients (78 nodules) in the EGFR mutation group and 28 patients (28 nodules) in the EGFR wild group. Adenocarcinomas with EGFR mutation showed significantly higher spiculated edge, pleural depression sign and invasive adenocarcinoma proportions than those in EGFR wild group ( P<0.05). There were no significant differences in other indicators between groups ( P>0.05). After adjusting for age and fasting blood glucose, gender and the number of GGNs significantly affected the relationship between SUV max and EGFR mutation ( P<0.05), which suggested that there was an interaction. After adjusting for confounding factors, there was a non-linear relationship between SUV max and EGFR mutation status in female subgroup (degree of freedom was 1.817, P=0.026). When SUV max<2.4, the risk of EGFR mutation increased significantly with the increase of SUV max (OR=43.621, 95%CI 4.686-406.042), P<0.001]. When SUV max>2.4, the risk of EGFR mutation increased insignificantly ( P=0.392). Conclusions:Lung adenocarcinoma appearing as GGN has a higher risk of EGFR mutation. The risk of EGFR mutation in female patients increases with increasing SUV max, but there is saturation effect.
