Objective: To analyze the epidemiological characteristics of infectious diseases among children and adolescents in Lanshan District, Linyi City, 2014-2023,so as to provide a scientific basis for prevention and control strategies in schools. Methods: The surveillance data were obtained from the China Information System for Disease Control and Prevention (CISDCP). Data on reported infectious disease cases and related demographic information among school children and kindergarteners in the study area from 2014 to 2023 were collected. Rate comparison was performed by using the χ 2 test. Trend analysis was conducted by using Joinpoint Regression Progrom, and the annual percent change (APC) and average annual percent change (AAPC) were calculated. Results: A total of 10 222 cases of infectious diseases among children and adolescents were reported from 2014 to 2023, with an average annual incidence rate of 273.32 per 100 000. The overall incidence trend remained stable from 2014 to 2023 (AAPC=12.33%, 95%CI=-2.63%-29.59%, P >0.05). Whereas a significant upward trend was observed from 2014 to 2019 (AAPC=37.08%, 95% CI =12.92%-66.41%, P <0.05), followed by a stable trend from 2019 to 2023 (AAPC=-0.31%, 95%CI=-39.70%-64.83%, P>0.05). Seasonal distribution exhibited dual peaks in summer and winter. The incidence rate in urban areas(707.29/100 000) was significantly higher than that in rural areas(257.50/100 000), and the incidence rate among kindergarteners (325.49/100 000) was higher than that among school children (257.07/100 000) (χ2=1 518.60, 116.36, both P<0.01). The reported infectious diseases among children and adolescents were predominantly respiratory and intestinal infectious diseases, with incidence rates of 156.13/100 000 and 108.51/100 000, respectively. Hand, foot, and mouth disease (HFMD) was the predominant infectious disease among kindergarteners, accounting for 47.51%. Influenza was the leading condition in the primary school group, accounting for 38.64%, and other infectious diarrheal diseases were most common in junior and senior high school group, accounting for 53.34%. The top six diseases by incidence rate were other infectious diarrheal diseases(65.22/100 000), influenza(63.24/100 000), varicella(46.34/100 000), HFMD(41.07/100 000), mumps(23.42/100 000), and scarlet fever(10.56/100 000). Among them, the incidence of other infectious diarrheal diseases rose significantly (AAPC=35.31%, 95% CI =14.32%-60.14%, P <0.01). The trend transitioned from a rapid escalation during 2014-2019 (APC=69.98%, 95% CI =17.58%-145.74%, P =0.01) to a stable phase during 2019-2023 (APC=1.74%, 95% CI =-15.61%- 22.66%, P >0.05). Conclusions In Lanshan, urban educational institutions should prioritize the prevention and control of infectious diseases, with particular emphasis on other infectious diarrheal diseases, influenza and varicella. Targeted interventions should be implemented in accordance with seasonal patterns and the specific characteristics of the school age populations.

Objective To investigate the influencing factors and Traditional Chinese Medical(TCM)syndrome classification of skin pruritus in patients with maintenance hemodialysis(MHD).Methods A total of 174 hemodialysis patients who underwent regular dialysis in Zhejiang Chinese Medical University Affiliated Jiaxing TCM Hospital from July to September 2024 were selected as study subjects.According to the presence or absence of uremic pruritus(UP),they were divided into pruritus group(n=66)and non-pruritus group(n=108).Both groups of patients were classified into TCM syndromes,and the factors affecting skin pruritus in MHD patients were analyzed by Logistic regression analysis and an evaluation model was established.The evaluation efficiency of the model was evaluated by receiver operating characteristic curve.The relationship between TCM syndromes and pruritus degree was analyzed.Results Both groups of patients were mainly characterized by spleen and kidney Qi deficiency,and the difference was statistically significant(P＜0.05).Logistic regression analysis showed that β2 microglobulin(β2-MG),blood phosphorus,hyper-sensitive C-reactive protein and parathyroid hormone(PTH)were all risk factors for skin pruritus in MHD patients.The area under the curve of skin pruritus in MHD patients was 0.962(95％CI:0.930-0.995).The underlying syndrome of UP patients was mainly spleen and kidney Qi deficiency,and marked syndrome was mainly blood deficiency and wind-dryness.Conclusion β2-MG,blood phosphorus,hyper-sensitive C-reactive protein and PTH are closely related to the occurrence of skin pruritus in MHD patients.The TCM syndrome of UP patients is mainly characterized by spleen and kidney Qi deficiency,and syndrome of blood deficiency and wind-dryness is mainly characterized by UP patients,and there is a certain correlation between TCM syndrome classification and the degree of skin pruritus.

High mobility group box 1 (HMGB1), when released extracellularly, plays a pivotal role in the development of spinal cord synapses and exacerbates autoimmune diseases within the central nervous system. In experimental autoimmune encephalomyelitis (EAE), a condition that models multiple sclerosis, the levels of extracellular HMGB1 and interleukin-33 (IL-33) have been found to be inversely correlated. However, the mechanism by which IL-33 deficiency enhances HMGB1 release during EAE remains elusive. Our study elucidates a potential signaling pathway whereby the absence of IL-33 leads to increased binding of P300/CBP-associated factor with HMGB1 in the nuclei of astrocytes, upregulating HMGB1 acetylation and promoting its release from astrocyte nuclei in the spinal cord of EAE mice. Conversely, the addition of IL-33 counteracts the TNF-α-induced increase in HMGB1 and acetylated HMGB1 levels in primary astrocytes. These findings underscore the potential of IL-33-associated signaling pathways as a therapeutic target for EAE treatment.

OBJECTIVE: To explore the peripheral neural mechanism underlying representation along the distribution of stomach meridian induced by intestinal inflammatory reaction using diarrhea predominant-irritable bowel syndrome (IBS-D) mice. METHODS: Among 62 healthy male C57BL/6 mice of clean grade, 12 mice were randomly selected and divided into a control group and a model group, 6 mice in each group, additionally, 12 mice were randomly selected and divided into a Tianshu group, a Liangqiu group and a Zusanli group, 4 mice in each group. In the model group, citrobacter was administered orally to establish IBS-D model. In the control group and the model group, the visceral pain threshold was observed using fecal colorectal distension (fCRD) induced electromyography of external oblique muscle, the positive cell number of neutrophil in the colonic muscularis was detected by myeloperoxidase (MPO) staining, the number, location and distribution rule of Evans blue (EB) extravasation points were observed by injection of EB staining solution into the tail vein. In the Tianshu group, the Liangqiu group and the Zusanli group, fluorescent dye Dil was injected at bilateral "Tianshu" (ST25), "Liangqiu" (ST34) and "Zusanli" (ST36) respectively, to observe the dye-positive cell number in different dorsal root ganglion (DRG) segments. In the control group and the model group, the activation of satellite glial cells (SGCs) in different DRG segments was observed by immunofluorescence. RESULTS: Compared with the control group, in the model group, the area under curve of electromyography of external oblique muscle was increased at fCRD of 25, 50 and 75 μL distilled water (P<0.001, P<0.01); the MPO-positive cell number of neutrophil in the colonic muscularis was increased (P<0.01). Few EB extravasation points could be found in the control group, while there were much more EB extravasation points observed in the model group, which was specially distribution in the area of stomach meridian, from "Huaroumen" (ST24) to "Zusanli" (ST36), as well as the surface area dominated by L₂-L₅ segment of the spinal cord. The Dil-positive cells were mainly exhibited in the DRG of T₁₁, L₅ and L₄ segments in the Tianshu group, the Liangqiu group and the Zusanli group, respectively. Compared with the control group, the ratio of glial fibrillary acidic protein (GFAP)/glutamine synthetase (GS) co-expression was increased in the DRG of T₁₁, L₄ and L₅ segments in the model group (P<0.05, P<0.01). CONCLUSION The activation of SGCs within DRG of T₁₁, L₄ and L₅ segments may relate closely to the occurrence of the representation along the stomach meridian distribution in IBS-D mice.

The ninth edition of TNM staging for lung cancer has been announced at the 2023 World Lung Cancer Congress and implemented from January 1, 2024. The focus of the ninth TNM staging change is dividing N2 into N2a and N2b, as well as M1c into M1c1 and M1c2. Although the T staging has not changed, it has played an important role in verifying the eighth edition of the T staging. The subdivision of stage N2 has led some patients with ⅢA of the eighth edition to experience ascending or descending stages, which will more accurately help to assess the condition and prognosis of patients with mediastinal lymph node metastasis, as well as the design of related clinical studies. Modifying the M1c staging will help define oligometastasis and explore new treatment models in the future. The ninth edition of the TNM staging system provides a more detailed division of different tumor loads, but there is no clear explanation for the staging of lung cancer after neoadjuvant therapy. Further data analysis is needed, and it is expected to be answered in the tenth edition of TNM staging.
