Objective To investigate the prevalence of tension-type headache(TTH)in children and adolescents aged 0-19 years globally in 1990-2021,and to provide a basis for the prevention and treatment of TTH.Methods Based on the Global Burden of Disease Study data,the age-standardized prevalence distribution of TTH and its changing trend were analyzed among the children and adolescents aged 0-19 years,with different sexes,age groups,sociodemographic index(SDI)regions and countries/territories.Results The age-standardized prevalence rate(ASPR)of TTH in children and adolescents aged 0-19 globally in 2021 was 17 339.89/100 000,which was increased by 1.73%since 1990.The ASPR in females was slightly higher than that in males(1990:17 707.65/100 000 vs 16 403.78/100 000;2021:17 946.29/100 000 vs 16 763.09/100 000).The ASPR in adolescence was significantly higher than that in school-aged and preschool periods(1990:27 672.04/100 000 vs 10 134.16/100 000;2021:28 239.04/100 000 vs 10 059.39/100 000).Regions with high SDI exhibited a higher ASPR than the other regions,with significant differences in prevalence rates across different countries.From 1990 to 2021,there was a slight increase in global ASPR,with an average annual percentage change(AAPC)of 0.06%.Females experienced a smaller increase than males based on AAPC(0.04%vs 0.07%).There was reduction in ASPR in preschool and school-aged groups,with an AAPC of-0.02%,while there was a significant increase in ASPR in adolescence,with an AAPC of 0.07%.ASPR decreased in regions with low-middle and low levels of SDI,with an AAPC of-0.02%and-0.04%,respectively,while it increased in regions with middle SDI,with an AAPC of 0.24%.Conclusions There is a consistent increase in the ASPR of TTH in children and adolescents aged 0-19 years globally,with significant differences across sexes,age groups,SDI regions and countries/territories.

Aim To study the proliferation,invasion and migration ability of Quaking(QKI)in gastric cancer(GC)via elucidating the molecular mechanisms associated with QKI in the occurrence and development of GC through bioinformatics.Methods Differential expression analysis of QKI was performed across vari-ous human cancer samples by merging data from the TCGA and GTEx databases.The correlation was ana-lyzed between QKI protein expression and tumor muta-tion burden(TMB)score,microsatellite instability(MSI)score,and ESTIMATE score,and the correla-tion was also explored between QKI protein expression and overall survival(OS),disease free survival(DFS),and progression free survival(PFS).EMT related genes that could encode DECircRNAs were ob-tained through bioinformatics analysis to construct a QKI-EMT-circRNAs regulatory network.The differenti-ally expressed circRNAs and EMT related genes in TMK1 cells were verified.The proliferation,invasion and migration ability of the QKI was studied by using the knockdown system.Results QKI was differential-ly expressed in the vast majority of tumors and was closely related to TMB,MSI,and tumor microenviron-ment(TME);QKI emerged as a high-risk factor for predicting OS,DFS,and PFS in individuals with com-mon human cancers.QKI regulated the splicing of 6 EMT related gene transcripts to form eight circRNAs,all of which were significantly associated with the prog-nosis of gastric cancer patients.Cell experiments showed that compared to normal gastric epithelial cells,only hsa_ccirc_0004015,CALD1,and CDK14 were down-regulated in TMK1 cells.Knocking down QKI inhibited the proliferation,invasion and migration ability of TMK1 cells.Conclusion QKI exerts regu-latory control over the transcription of six EMT-related genes,resulting in the formation of circRNAs,thereby promoting the pathogenesis and progression of GC.QKI is highly expressed in TMK1 cells,and knock-down of QKI can inhibit the proliferation,invasion and migration ability of TMK1 cells.

Aim To investigate the effect of paeonol(PAE)on cardiac hypertrophy induced by Angio-tensinogen Ⅱ(Ang Ⅱ)in rats and its mechanism.Methods Forty Sprague-Dawley rats were divided in-to five groups:control group,Ang Ⅱ model group,low concentration paeonol group,middle concentration pae-onol group,high concentration paeonol group.PAE was administered intragastrically(25,50 and 100 mg·kg-1·d-1)for 28 days.The hypertrophic model was established by adding 1 μmol·L-1 Ang Ⅱ to H9c2 cells for 48 hours.Results In Ang Ⅱ-induced rats,PAE improved echocardiography parameters,the cardi-ac hypertrophy index,the mRNA and protein expres-sion levels of ANP and BNP were decreased,and the cardiac fibrosis was alleviated.In vitro,PAE reduced cardiomyocyte hypertrophy and decreased the mRNA and protein expression levels of ANP and BNP in H9c2 cells induced by Ang Ⅱ,at the same time,the expres-sion of endoplasmic reticulum stress marker proteins p-PERK,GRP78,ATF4 and CHOP were decreased and reversed after treatment with the endoplasmic reticulum stress agonist tunicamycin(TN).Conclusion This study suggests that PAE can improve cardiac hypertro-phy by inhibiting endoplasmic reticulum stress,which may be a new drug to delay the development of cardiac hypertrophy.

Refractory prolactinoma is the most common pituitary neuroendocrine tumor.Dopamine receptor agonists(DA)are the primary choice for drug treatment.Most patients with prolactinomas respond well to DA.However,a minority of prolactinomas patients still show resistance to DA.Although drug-resistant and refractory prolactinomas are rare in clinical practice,their treatment is extremely challenging.Even a combination of drug therapy,multiple surgeries,and radiotherapy may not yield satisfactory outcomes.Therefore,standardizing the diagnosis and treatment process and pathway for refractory prolactionmas and exploring more effective multidisciplinary collaborative treatment strategies are urgent problems to be solved.In the clinical management of refractory prolactinomas,it is often necessary to consider the patient's condition comprehensively,replace other types of DA,or consider surgery,radiotherapy,and immunotherapy,which requires multidisciplinary diagnosis and treatment.This review synthesizes the latest literature at home and abroad to systematically discuss the latest advances in drug therapy,surgery,and radiotherapy treatments for refractory prolactionmas,aiming to provide new ideas for basic research,clinical diagnosis and treatment.

Objective To investigate the effect of nobiletin on platelet-activating factor(PAF)metabolism in diabetic rats with renal injury.Methods Totally 72 rats were randomly divided into control group(n=10)and modeling group(n=62).The modeling group rats were induced to develop a diabetic rat model with renal injury and then further divided into the model group,aspirin group(20 mg/kg),and nobiletin low(50 mg/kg),medium(100 mg/kg),and high-dose(200 mg/kg)groups,each with 10 rats.After continuous oral administration for 6 weeks,rat body weight,kidney weight,and kidney index were measured.Histopathological assessments were conducted by using HE,periodic acid-Schiff staining(PAS),Masson staining,and transmission electron microscopy.Blood glucose levels,renal function,inflammatory factors,PAF and its regulatory factors were detected.Expression levels of PAF metabolism-related proteins,PAF-acetylhydrolase(PAFAH),PAF receptor(PAFR),and cholinephosphotransferase 1(CHPT1)in kidney tissues were assessed using Western blotting and immunohistochemistry.Results Following nobiletin intervention,rat body weight increased while kidney weight and kidney index decreased.Improvement in renal tissue pathology was observed,with reduced interstitial fibrosis and thinner basement membrane.Fasting blood glucose and glycated hemoglobin decreased,while fasting insulin showed no significant improvement.Urea nitrogen,blood creatinine,cystatin C,and 24-hour urinary protein excretion were reduced.Levels of interleukin(IL)-1α,IL-6,IL-8,and tumor necrosis factor(TNF-α)were lowered.PAF and its regulatory factors decreased.PAFR and CHPT1 expression decreased,while PAFAH increased.Conclusion Nobiletin can alleviate renal injury in diabetic rats with renal injury,improve kidney function,regulate blood glucose,and mitigate inflammatory response.Its mechanism may be associated with the modulation of platelet-activating factor metabolism.

This study aimed to explore the potentiating effect and mechanism of the extract of Jingfang Granules(JFG) on the activation of macrophages. The RAW264.7 cells were treated with JFG extract and then stimulated by multiple agents. Subsequently, mRNA was extracted, and reverse transcription-polymerase chain reaction(RT-PCR) was used to measure the mRNA transcription of multiple cytokines in RAW264.7 cells. The levels of cytokines in the cell supernatant were detected by enzyme-linked immunosorbent assay(ELISA). In addition, the intracellular proteins were extracted and the activation of signaling pathways was determined by Western blot. The results showed that JFG extract alone could not promote or slightly promote the mRNA transcription of TNF-α, IL-6, IL-1β, MIP-1α, MCP-1, CCL5, IP-10, and IFN-β, and significantly enhance the mRNA transcription of these cytokines in RAW264.7 cells induced by R848 and CpG in a dose-dependent manner. Furthermore, JFG extract also potentiated the secretion of TNF-α, IL-6, MCP-1, and IFN-β by RAW264.7 cells stimulated with R848 and CpG. As revealed by mechanism analysis, JFG extract enhanced the phosphorylation of p38, ERK1/2, IRF3, STAT1, and STAT3 in RAW264.7 cells induced by CpG. The findings of this study indicate that JFG extract can selectively potentiate the activation of macrophages induced by R848 and CpG, which may be attributed to the promotion of the activation of MAPKs, IRF3, and STAT1/3 signaling pathways.

In 2021, a total of 151 pregnant women were selected from the suburb of Shanghai. A questionnaire survey was conducted to obtain data about maternal age, gestational week, total annual household income, education level and passive smoking among pregnant women and one spot urine was collected. The concentrations of eight neonicotinoid pesticides and four metabolites in urine were measured by ultra-high performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry. The differences in detection frequencies and concentrations of neonicotinoid pesticides and their metabolites among pregnant women with different characteristics were compared, and the influencing factors of the detection of neonicotinoid pesticides in urine were analyzed. The results showed that at least one neonicotinoid pesticide was detected in 93.4% (141 samples) of urine samples. The detection frequencies of N-desmethyl-acetamiprid, clothianidin, thiamethoxam, and N-desmethyl-clothianidin were high, about 78.1% (118 samples), 75.5% (114 samples), 68.9% (104 samples), and 44.4% (67 samples), respectively. The median concentration of the sum of all neonicotinoid pesticides was 2.66 μg/g. N-desmethyl-acetamiprid had the highest detection concentration with a median concentration of 1.04 μg/g. A lower urinary detection frequency of imidacloprid and its metabolites was seen in pregnant women aged 30-44 years [OR (95%CI): 0.23 (0.07-0.77)]. A higher detection frequency of clothianidin and its metabolites was seen in pregnant women with per capita annual household income≥100 000 yuan [OR (95%CI): 6.15 (1.56-24.28)]. There was widespread exposure to neonicotinoid pesticides and their metabolites in pregnant women from the suburb of Shanghai, which might pose potential health risks to pregnant women, and maternal age and household income were potential influencing factors of the exposure to neonicotinoid pesticides.

Objective: To report the clinical manifestations and laboratory features of five patients with congenital thrombotic thrombocytopenic purpura (cTTP) and explore its standardized clinical diagnosis and treatment along with a review of literature. Methods: Clinical data of patients, such as age of onset, disease manifestation, personal history, family history, and misdiagnosed disease, were collected. Treatment outcomes, therapeutic effects of plasma infusion, and organ function evaluation were observed. The relationship among the clinical manifestations, treatment outcomes, and ADAMTS13 gene mutation of patients with cTTP was analyzed. Additionally, detection of ADAMTS13 activity and analysis of ADAMTS13 gene mutation were explored. Results: The age of onset of cTTP was either in childhood or adulthood except in one case, which was at the age of 1. The primary manifestations were obvious thrombocytopenia, anemia, and different degrees of nervous system involvement. Most of the patients were initially suspected of having immune thrombocytopenia. Acute cTTP was induced by pregnancy and infection in two and one case, respectively. ADAMTS13 gene mutation was detected in all cases, and there was an inherent relationship between the mutation site, clinical manifestations, and degree of organ injury. Therapeutic or prophylactic plasma transfusion was effective for treating cTTP. Conclusions: The clinical manifestations of cTTP vary among individuals, resulting in frequent misdiagnosis that delays treatment. ADAMTS13 activity detection in plasma and ADAMTS13 gene mutation analysis are important bases to diagnose cTTP. Prophylactic plasma transfusion is vital to prevent the onset of the disease.
