Head and neck squamous cell carcinoma(HNSCC)is a highly prevalent malignancy with poor prognosis.Treatment strategies to date have achieved limited success in significantly improving overall survival rates.γδ T cells,a unique subset of immune cells in the tumor microenvironment,can link adaptive and innate immune functions.While γδ T cells can effectively recognize and eliminate HNSCC tumor cells,certain subsets of these cells can secrete interleukin-17,contributing to tumor progression.Nevertheless,due to their remarkable cyto-toxic activity,γδ T cells have been identified as promising candidates for antitumor immunotherapy.This article reviews the biological back-ground of γδ T cells,their role in tumor immunity in HNSCC,and recent advances in γδ T cell immunotherapy,aiming to provide new in-sights into HNSCC diagnosis and treatment.

Objective:To evalaute the prevalence and determinants of thyroid nodules in children and adolescents in Jiangsu Province.Methods:This study included in-school students aged 8-17 years and selected through stratified cluster random sampling in Jiangsu. Thyroid nodule was diagnosed when its diameter was ≥3 mm. Random urine samples were collected for the detection of urinary iodine concentration with arsenic-cerium catalytic spectrophotometry. Data were analyzed by using χ2 test and logistic regression model. Results:In the 8 201 children and adolescents selected, the thyroid nodule detection rate was 16.10%. Multivariate logistic regression analysis revealed that, compared with those with urinary iodine levels of 100-299 μg/L, boys, those with normal body weight, those who were satisfied with their school performance, urinary iodine concentration ≥300 μg/L ( OR=1.15, 95% CI: 1.01-1.31), being girls ( OR=1.42, 95% CI: 1.26-1.60), being overweight ( OR=1.27, 95% CI: 1.07-1.50), being obese ( OR=1.23, 95% CI: 1.03-1.47), and dissatisfied with school performance ( OR=1.22, 95% CI: 1.04-1.43) were associated with higher likelihood of thyroid nodule detection. Children and adolescents who had solid snacks 2 times per week to 2 times per month ( OR=0.86, 95% CI: 0.74-0.99) or less than 2 times per month ( OR=0.80, 95% CI: 0.68-0.93) were more likely to have lower detection rate compared with those who had solid snacks more than 2 times per week. The detection rate of thyroid nodule increased with age ( OR=1.09, 95% CI: 1.06-1.11). Conclusion:The main factors influencing the detection rate of thyroid nodule in children and adolescents aged 8-17 years in Jiangsu included gender, age, urinary iodine concentration, BMI, self-assessed school performance and dietary habit.

Malignant insulinoma is a kind of rare and challenging neuroendocrine tumor. It is often accompanied by distant metastasis, among which liver metastasis is most common, and the prognosis is often non-promising. In this paper, we report a case of multiple liver metastases from malignant insulinoma. The patient, a 70-year-old male, was admitted to the hospital due to "episodic consciousness disorder for more than four months." Blood glucose monitoring revealed recurrent hypoglycemia in the early morning, after meals, and at night. Pancreatic perfusion CT and dynamic enhanced MRI of the liver revealed a mass in the uncinate process of the pancreatic head and multiple liver metastases. Percutaneous liver biopsy confirmed the diagnosis of insulinoma. After multidisciplinary discussions, hepatic artery embolization and radiofrequency ablation were performed in stages, in combination with everolimus treatment. Thereafter, the enhanced CT demonstrated that some liver metastases shrank. The patient had regular meals, and the blood sugar gradually increased and remained normal thereafter. This article discusses this case's clinical characteristics and multidisciplinary collaborative diagnosis and treatment, aiming to provide experience for the comprehensive clinical diagnosis and treatment of malignant insulinoma patients.

BACKGROUND:A pathophysiological feature of septic organ failure is endothelial dysfunction in sepsis(EDS).The physiological and pathological mechanism of sepsis is considered to be vascular leakage caused by endothelial dysfunction.These pathological changes lead to systemic organ injury.However,an analysis using bibliometric methods has not yet been conducted in the field of EDS.This study was conducted to provide an overview of knowledge structure and research trends in the field of EDS. METHODS:Based on previous research,a literature search was performed in the Web of Science Core Collection(WoSCC)for publications associated with EDS published between the year 2003 and 2023.Various types of data from the publications,such as citation frequency,authorship,keywords and highly cited articles,were extracted.The"Create Citation Report"feature in the WoSCC was employed to calculate the Hirsch index(h-index)and average citations per item(ACI)of authors,institutions,and countries.To conduct bibliometric and visualization analyses,three bibliometric tools were used,including R-bibliometrix,CiteSpace(co-citation analysis of references),and VOSviewer(co-authorship analysis of institutions,co-authorship analysis of authors,co-occurrence analysis of keywords). RESULTS:After excluding invalid records,the study finaly included 4,536 publications with 135,386 citations.Most of these publications originated in the USA,China,Germany,Canada,and Japan.Harvard University emerged as the most prolific institution,while professor Jong-Sup Bae and his research team at Kyungpook National University emerged as authors with the greatest influence.The"protein C","tissue factor","thrombin","glycocalyx","acute kidney injury","syndecan-1"and"biomarker"were identified as prominent areas of research.Future research may focus on molecular mechanisms(such as as vascular endothelial[VE]-cadherin regulation)and therapeutic interventions to enhance endothelial repair and function. CONCLUSION:Our findings show a growing interest in EDS research.Key areas for future research include signaling pathways,molecular mechanisms,endothelial repair,and interactions between endothelial cells and other cell types in sepsis.

Objective The aim of this study was to investigate the role of long chain non-coding RNA LINC-PINT in drug sensitivity of hypoxia induced in head and neck squamous cell carcinoma(HNSCC)through the Hippo/Yes-associated protein(YAP)signaling pathway.Methods The proliferative changes of HNSCC cell lines(AGZY-973 cells,HN4 cells,and HN30 cells)and nor-mal human oral keratinocytes(NHOKs)in hypoxic environment were detected by CCK-8 assay;HN30 cells in good condition were taken and set them as the normal group,hypoxia group,hypoxia+LINC-PINT overexpression group,and hypoxia+overexpression negative control group.The expression of LINC-PINT in HN30 cells was detected by qRT-PCR;CCK-8 assay was applied to de-tect the drug sensitivity of HN30 cells,and the effect of cisplatin on proliferation in HN30 cells;cell apoptosis was detected by flow cy-tometry;and Western blot was applied to detect the expression of hypoxia inducible factor-1α(HIF-1α),p-YAP,and YAP protein in HN30 cells.Results Under hypoxia conditions,the proliferative rates of AGZY-973 cells,HN4 cells and HN30 cells were obvi-ously higher than that of NHOKs cells(P＜0.05).Compared with the normal group,the IC50 value,the expression of HIF-1 α and p-YAP/YAP in the hypoxic group were obviously increased in HN30 cells,the rate of apoptosis,the rates of cell growth inhibition at 24 h and 48 h,and the expression of LINC-PINT protein were obviously decreased(P＜0.05);Compared with the hypoxia+overex-pression negative control group,the IC50 values,the expression of HIF-1α and p-YAP/YAP cells in the hypoxia overexpression of LINC-PINT group was obviously reduced in HN30,the rates of apoptosis,the rates of cell growth inhibition at 24 h and 48 h,and the expression of LINC-PINT protein were significantly increased(P＜0.05).Conclusion Overexpression of LINC-PINT can en-hance the hypoxia-induced cisplatin sensitivity in HNSCC,which may be related to the inhibition of the activation of Hippo/YAP sig-naling pathway.

Objective:To learn about the implementation of prevention and control measures in drinking water-borne endemic fluorosis areas and the trend of the disease change in Jiangsu Province.Methods:In March to October 2021, a general survey was carried out in 1 972 villages with drinking water-borne endemic fluorosis in 27 counties (cities and districts) of Jiangsu Province, the operation of water improvement projects in the villages was monitored, and the water fluoride content was determined. The prevalence of dental fluorosis among children aged 8 to 12 years in all the villages was investigated.Results:The 1 972 villages with drinking water-borne endemic fluorosis had completed water improvement, and all water improvement projects were operating normally and the water was qualified. Among them, 1 774 villages in the disease affected areas had achieved the control goal, accounting for 89.96%; and there were 198 villages in the disease affected areas with control measures up to the standard, accounting for 10.04%. A total of 47 water improvement projects were monitored, including 2 small-scale water improvement projects, accounting for 4.26%. There were 45 large-scale water improvement projects, accounting for 95.74%. A total of 125 790 children aged 8 to 12 years were examined, and 12 625 cases of dental fluorosis were detected. The detection rate of dental fluorosis was 10.04%, and the dental fluorosis index was 0.19. The detection rate of dental fluorosis in children aged 8 to 12 years was 9.98% (1 854/18 579), 10.27% (2 704/26 323), 9.48% (2 765/29 152), 9.73% (2 835/29 145) and 10.92% (2 467/22 591), respectively, with statistically significant difference (χ 2 = 10.51, P = 0.015). Among the 198 villages with control measures up to standard, according to the historical water fluoride, the detection rate of dental fluorosis in children in each water fluoride range (1.20-2.00, 2.01-3.00, 3.01-4.00, > 4.00 mg/L) was 37.73% (698/1 850), 43.17% (1 176/2 724), 45.50% (769/1 690) and 55.20% (802/1 453), respectively, with a statistically significant difference (χ 2 = 104.15, P < 0.001). Conclusion:The water improvement measures in drinking water-borne endemic fluorosis areas in Jiangsu Province have achieved significant results, which still need to be further consolidated.

Objective:To dynamically observe the changes in iodine level in residents' drinking water after the change of regional water supply mode (2020) in Jiangsu Province.Methods:The survey of water iodine level was conducted from June to October 2020 in administrative villages of Jiangsu Province with a median water iodine ≥40 μg/L in 2017. The survey mainly covered 1 537 administrative villages in 21 counties (cities and districts) of 5 cities, including Huaian City, Lianyungang City, Suqian City, Yancheng City, and Xuzhou City. Based on the standard of "Definition and Demarcation of Iodine Deficient Areas and Iodine Adequate Areas" (WS/T 669-2020), the administrative villages with a median water iodine of 40 - 100 μg/L were classified as iodine adequate areas. Water iodine testing was conducted using the "Method for Water Iodine Testing in Iodine Deficient and High Iodine Areas" recommended by the National Reference Laboratory for Iodine Deficiency Disorders.Results:Totally 1 498 administrative villages in Jiangsu Province were monitored in 2020, all of which had centralized water supply. The minimum value of water iodine in all administrative villages was 1.2 μg/L and the maximum value was 606.7 μg/L, and the median water iodine was 35.2 μg/L. Among them, 206 administrative villages had median water iodine < 10 μg/L, accounting for 13.75% (206/1 498); 610 administrative villages had median water iodine from 10 to < 40 μg/L, accounting for 40.72% (610/1 498); 635 administrative villages had median water iodine from 40 to 100 μg/L, accounting for 42.39% (635/1 498); and 47 administrative villages with median water iodine > 100 μg/L, accounting for 3.14% (47/1 498). Except for Sucheng District in Suqian City, Xinyi City and Gulou District in Xuzhou City, Qingjiangpu District and Xuyi County in Huaian City, and Guannan County in Lianyungang City, the median water iodine in the administrative villages of the remaining 15 counties (cities and districts) in 2020 decreased significantly compared to 2017, and the differences were statistically significant ( P < 0.05). Conclusion:After change of regional water supply mode in 2020, in most monitored counties (cities and districts) of Jiangsu Province, the water iodine level of administrative villages has decreased significantly compared to 2017.

Objective:To analyze the iodine nutrition status of key populations in water source high iodine areas in Jiangsu Province, providing a reference for scientific prevention and control of water source high iodine hazards.Methods:From May to June 2020, monitoring sites were determined by administrative villages in six high iodine counties (cities, districts) in Jiangsu Province, and drinking water samples were collected from residents to detect the iodine content in the water; 40 non boarding children aged 8 - 10 from one primary school in each village (half male and half female, with an age balance) and 20 pregnant women were selected. Salt samples were taken from children and pregnant women's homes, and urine samples were randomly taken once to detect salt and urine iodine contents. Thyroid volume of children was examined.Results:A total of 36 administrative villages were monitored, with a median of 45.3 μg/L for water iodine, ranging from 8.5 - 372.1 μg/L. A total of 1 422 salt samples were collected, of which 26 were iodized salt, accounting for 1.83%; and 1 396 non iodized salt, with the coverage rate of non iodized salt was 98.17%. A total of 1 365 urine samples were collected from children, with a median urine iodine of 405.6 μg/L. There were statistically significant differences in urine iodine levels among children in different regions, drinking water iodine contents, and age groups ( H = 128.39, 67.81, 39.94, P < 0.001). A total of 57 urine samples were collected from pregnant women, with a median urine iodine of 282.0 μg/L. There were statistically significant differences in urine iodine levels among pregnant women in different regions and drinking water iodine contents groups ( H = 17.54, 18.39, P < 0.001). A total of 1 365 children's thyroid volumes were examined, and 44 cases of thyroid enlargement were detected, with a goiter rate of 3.22%. There were no statistically significant differences in the incidence of thyroid enlargement among children in different regions, drinking water iodine contents, salt types, gender, and age groups ( P > 0.05). Conclusions:The iodine nutrition of children in water source high iodine areas in Jiangsu Province is at an iodine excess level, while the iodine nutrition of pregnant women is at an over optimal level. In areas with high iodine content in water sources, the iodine content in drinking water has a significant impact on the iodine intake of the local population. There is currently no correlation between the iodine content in drinking water, salt type, gender, and age factors and thyroid enlargement in children.
