Aim To investigate the effect and mechanism of angiotensin Ⅱ(Ang Ⅱ)on ferroptosis in white adi-pocytes.Methods The 3T3-L1 preadipocytes were differentiated into white adipocytes by inducer stimulation.The experiment was divided into control group,Ang Ⅱ group,Ang Ⅱ+Fer-1(ferroptosis inhibitor)group and Ang Ⅱ+PFT-α(p53 inhibitor)group.Ang Ⅱ was used to treat cells.RT-qPCR and Western blot were used to detect the expression levels of ferroptosis factors and adipokines.JC-1 kit was used to detect mitochondrial membrane potential(MMP)level.Iron ion kit was used to detect intracellular iron content.Glutathione(GSH)kit was used to detect GSH content.Fer-1 and Ang Ⅱ were added to treat cells to detect the the changes of ferroptosis level.The expression of p53 and spermidine/spermine N1-acetyltransferase 1(SAT1)protein was detected.Subsequently,PFT-α and Ang Ⅱ were added to co-treat cells to detect the changes of p53 and SAT1 protein expression,and to observe the effect of inhibiting p53 expression on the expression levels of ferroptosis factors and adipokines.Results 3T3-L1 cells were successfully differentiated into white adipocytes by stimulator-induced differentiation.Ang Ⅱ induced ferroptosis in white adipocytes.RT-qPCR results showed that compared with control group,the mRNA expression of anti-ferroptosis factor glutathione peroxidase 4(GPX4),solute carrier family 7 member 11(SLC7A11)and iron regulatory protein 1(IRP-1)was down-regulated in Ang Ⅱ group,and the mRNA expression of pro-ferroptosis factor acyl-CoA synthetase of long-chain family member 4(ACSL4)was up-regulated.Western blot results showed that compared with control group,the protein expression of SLC7A11 and GPX4 was down-regulated in Ang Ⅱ group,and the protein expression of ACSL4 was up-regulated.Ang Ⅱ treatment increased the content of intracellular iron ions and decreased the levels of GSH and MMP.Compared with Ang Ⅱ group,the mRNA expression of IRP-1 and SLC7A11 was up-regulated in Ang Ⅱ+Fer-1 group.Ang Ⅱ induced changes in the expression profile of adipokines in white adipocytes.Western blot results showed that compared with control group,the protein ex-pression of pro-inflammatory adipokine leptin(LEP),resistin(RETN),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)was up-regulated in Ang Ⅱ group,and the protein expression of anti-inflammatory adipokine adiponectin(AD-PN)and omentin 1(ITLN1)was down-regulated.In addition,Ang Ⅱ increased the protein expression of p53 and SAT1.Inhibition of p53 expression can improve the level of ferroptosis and adipokine expression in white adipocytes trea-ted with Ang Ⅱ.Western blot results showed that compared with Ang Ⅱ group,the protein expression of p53 and SAT1 was down-regulated in Ang Ⅱ+PFT-α group,the protein expression of SLC7A11 and GPX4 was up-regulated,and the protein expression of ACSL4 was down-regulated.The protein expression of ADPN was up-regulated in Ang Ⅱ+PFT-αgroup,and the protein expression of TNF-α,LEP and RETN was down-regulated.Conclusion Ang Ⅱ induces fer-roptosis in white adipocytes through activating the p53/SAT1 signaling pathway.

Tic disorders are common neurodevelopmental disorders in children, characterized by repetitive movements and/or vocal tics.In recent years, the incidence of tic disorders has been increasing, whose mechanism may be partially related to neurogenetic, neurobiochemical, neuroimmune, social and environmental factors.At present, studies have shown a possible association between vitamin D and tic disorders and that vitamin D supplementation may be used as an auxiliary therapy.In this article, the correlation between vitamin D and tic disorders is reviewed.The results provide new ideas for the treatment of tic disorders.

[Purpose]To analyze the preliminary screening and follow-up results of the early diag-nosis and treatment program for upper gastrointestinal cancer in rural areas of Fujian Province from 2013 to 2022.[Methods]Screening data from the early diagnosis and treatment program for upper gastrointestinal cancer in Fujian Province from 2013 to 2022 were collected and organized.The positive case detection rate,early diagnosis rate,and treatment rate of the screening population were calculated.SPSS 22.0 software was used to test the trend Chi-square test of the annual changes in detection rate,early diagnosis rate and treatment rate.The Chi-square test was used to compare the detection rate and early diagnosis rate between different groups.[Results]From 2013 to 2022,a total of 26 823 screenings and follow-ups were completed in Fujian Province,with de-tection rate,early diagnosis rate,and treatment rate of 1.41%,56.20%,and 92.61%,respec-tively.The early diagnosis rate showed an increasing trend from 2013 to 2022(P<0.05).The initial screening detected rate and early diagnosis rate were 1.38%and 55.59%,respectively,while fol-low-up detection rate and early diagnosis rate were 5.36%and 75.00%.The detection rates for esophagus,cardia,and stomach cases were 0.70%,0.15%,and 0.58%,respectively,with early diagnosis rates of 64.86%,53.66%,and 46.41%,respectively.The differences in detection rates and early diagnosis rates for each site were statistically significant(all P<0.05).[Conclusion]With the development of early diagnosis and treatment of upper gastrointestinal cancer in rural areas of Fujian Province and the improvement of residents'awareness of cancer prevention,the detection rate and early diagnosis rate of upper gastrointestinal cancer in Fujian Province have been im-proved,which plays an important role in improving the survival rate of patients.

Correctly identifying the treatment failure in chronic tic disorders can prevent the continued use of unnecessary treatments and facilitate timely escalation to experimental or even invasive treatment.However, there is still a lack of a standard definition for the treatment failure in chronic tic disorders.Led by Professor Davide Martino from the University of Calgary in Canada, several rounds of web-based Delphi surveys were conducted to formulate expert clinicians′ consensus-based definition for treatment failure in chronic tic disorders.This consensus defines the treatment failure in chronic tic disorders from 4 aspects of behavioral and pharmacological interventions: lack of efficacy, adherence, tolerability and behavioral disorders.In addition, it further defines the failure of behavioral intervention as a whole and pharmacological intervention as a whole.This article interprets the process and key contents of the consensus, and discusses the definition of refractory tic disorders to help clinicians improve their understanding of the treatment failure in chronic tic disorders.

Tic disorders(TD)are common neurodevelopmental disorders whose pathogenesis is unknown.As a non-invasive examination,electroencephalography(EEG)is widely used in the diagnosis of TD.Due to the high temporal resolution of the EEG signal,when combined with standardized analysis techniques,it can not only be used to understand the physiological functions of the subject,but also to reflect the pathophysiological changes of the disease.Based on the data analysis technology of EEG,this paper reviews the progress of brain connectivity and brain network analysis,time-frequency analysis,and EEG complexity of TD,summarizes the shortcomings of existing research,and provides new ideas for further in-depth study of its pathophysiological mechanism.

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.
