OBJECTIVE: To explore the current status, evolution, hot topics, and future research trends in the field of burn-related sepsis research through a visual analysis of literature. METHODS: A bibliometric method was employed to retrieve articles related to burn-related sepsis from January 1, 1994, to May 16, 2024, in the China National Knowledge Infrastructure (CNKI) and the Web of Science database. The CiteSpace 6.3.R1 software was used to analyze the retrieved literature. The number of publications, authors, countries, and institutions in both Chinese and English literature was statistically analyzed. Co-occurrence analysis, clustering analysis, and co-citation analysis of keywords were performed. RESULTS: A total of 1 090 articles from the CNKI database and 1 143 articles from the Web of Science database were retrieved. Over the past 20 years, the volume of Chinese publications has remained stable, although there has been a slight decline in the past two years. In contrast, the number of English publications, after a period of growth, showed a sharp decline over the past three years. In Chinese literature, 1 457 authors published articles on burn-related sepsis as first authors, with 14 core authors publishing four or more articles. In English literature, 98 authors published articles on burn-related sepsis as first authors. Research on burn-related sepsis was conducted by 76 countries, with the United States having the most collaborations and publications. Globally, 1 349 institutions published articles on burn-related sepsis, with the top institutions being the First Affiliated Hospital of the PLA General Hospital (8 articles) for Chinese literature and the University of Texas Medical Branch (57 articles) for English literature. In the co-occurrence analysis, 208 Chinese keywords and 211 English keywords were included. Excluding keywords related to search terms, the top five most frequent keywords in Chinese literature were burn, sepsis, infection, severe burn, and procalcitonin; the top five most frequent keywords in English literature were sepsis, septic shock, mortality, injury, and burn injury. Chinese keyword analysis identified six clusters, with the largest being sepsis, followed by procalcitonin, infection, and severe burn. English keyword analysis identified seven clusters, with the largest being expression, followed by epidemiology, inhalation injury, and acute kidney injury. The persistent clusters in Chinese literature were procalcitonin, with recent emerging nodes being severe burn, inflammatory response, platelets, and predictive value. In English literature, the persistent clusters were inhalation injury and nitric oxide, with recent emerging nodes being continuous renal replacement therapy, hemorrhagic shock, and early enteral nutrition. The longest-lasting emergent keyword in Chinese literature was delayed resuscitation (2003-2010), with the highest emergent strength being severe burn. In English literature, the longest-lasting emergent keywords, each lasting five years, were nitric oxide (2007-2012), management (2019-2024), and impact (2019-2024), with the highest emergent strength being thermal injury. CONCLUSIONS Research on burn-related sepsis has shifted from focusing on early studies on pathogenesis and mortality to focus on prevention, treatment, and early diagnosis. Future research is expected to focus on early diagnosis and risk factors of burn-related sepsis.

ObjectiveTo analyze the impact of diabetes-related deaths on the probability of premature mortality and life expectancy in Minhang District of Shanghai from 2004 to 2023, and to provide reference data for the optimization of targeted prevention and control strategies. MethodsAll death cases involving diabetes among the registered residents of Minhang District from 2004 to 2023 were collected. The probability of premature mortality and life expectancy was computed using the abridged life table method. The average annual percent change (AAPC) was calculated with Joinpoint 4.9.0.0. The Arriaga decomposition method was employed for statistical analyses of the influence of cause-specific and age-specific mortality related to diabetes on life expectancy. ResultsThe total number of diabetes-related mortality, crude mortality, and standardized mortality for both males and females in Minhang District from 2004 to 2023 exhibited an increasing trend (P<0.001). The primary causes of death among diabetes-related cases were cardiovascular disease (37.68%), diabetes mellitus (31.95%), and malignant tumor (17.80%). From 2004 to 2023, probability of premature mortality to diabetes-related diseases demonstrated a rising trend (P<0.001), contrasting with the declining trend observed in the overall population (P=0.001). Males showed a significant upward trajectory (P<0.001), while females displayed a stable pattern. Among the diseases exerting considerable influence, cardiovascular disease and malignant tumor revealed a marked increase over time (P<0.001), whereas diabetes mellitus maintained a stable trend; both factors negatively impacted the reduction in probability of premature mortality. From 2004 to 2023, diabetes-related mortality reduced life expectancy among residents by an average of 1.22 years (-49.89%), indicating a negative impact; the reduction was 1.41 years in males and 0.90 years in females. The age groups exhibiting greater negative contributions differed by genders, namely males aged 50‒54 years and females aged 70‒74 years. Cardiovascular disease, diabetes mellitus, and malignant tumor contributed significantly to this decline (-0.46 years, -0.42 years, -0.20 years, respectively), with male experiencing higher negative contributions than females. ConclusionIn Minhang District, the rising mortality associated with diabetes-related diseases negatively impact both the reduction of the probability of premature mortality and the increase in life expectancy. This trend is primarily attributed to the rapid escalation of mortality and younger age demographic of male residents, which warrants significant attention. It is recommended that, based on the enhancement of case management, efforts should be directed towards the targeted prevention and control of risk factors and high-risk populations.

Cardiomyopathy is a group of heterogeneous myocardial diseases with a variety of specific phenotypes that can lead to cardiovascular death or progressive heart failure in severe cases.Because of the severity and complexity of these diseases,the search for new regulatory mechanisms to prevent and treat cardiomyopathy is particularly urgent.Iron death is a form of programmed cell death that differs from other forms of iron dependence and is characterized by the accumulation of iron-dependent lipid peroxides.Studies have shown that iron death can be involved in the occurrence and progression of cardiomyopathy through different signaling pathways.Therefore,targeted regulation of iron death is a new strategy to prevent cardiomyopathy.In this paper,the mechanism of iron death and its important role in cardiomyopathy were reviewed to find the potential relationship between iron death and cardiomyopathy and provide more ideas for the treatment of various cardiomyopathies in the future.

Objective:To investigate the changes of thyroid hormones and the flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyrotoxicosis before and after treatment with methimazole.Methods:A case-control study was conducted to select 45 cases of Graves' disease and 45 cases of Hashimoto's thyroiditis from October 2021 to December 2022 in the Department of Endocrinology, North China University of Science and Technology Affiliated Hospital. The changes of thyroid hormone and blood flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyroiditis before and after treatment with methimazole were analyzed. Measurement data satisfying normal distribution were expressed by xˉ±s, and the mean between two groups was compared by t test. Measurement data not satisfying normal distribution were expressed by M( Q1, Q3), and the median between two groups was compared by Wilcoxon rank sum test. χ 2 test was used to compare the constituent ratio of enumeration data among groups. Results:There was no significant difference in thyroid stimulating hormone (TSH) between the two groups before treatment, and there was no significant difference in TSH between the two groups after 1 month and 3 months of treatment (all P>0.05). The levels of free triiodothyronine (FT3) were (24.09±9.29) pmol/L and (17.41±9.36) pmol/L in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. FT4 were (60.23±20.82) and (43.47±21.71) pmol/L, respectively, and the peak stolie vloiy (PSV) were (69.53±5.70) and (52.65±4.64) cm/s, respectively in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. There were significant differences between the two groups ( t values wrere 3.39 and 3.74, Z=13.83, all P<0.001). The difference of FT3 between one month after treatment and before treatment was (-6.36±5.32) and (-12.64±9.08) pmol/L ( t=4.02, P<0.001) and the difference in FT3 between 3 months of treatment and before treatment was (-10.14±9.50) and (-17.80±11.17) pmol/L, respectively ( t=3.51, P<0.001) between the Graves disease group and the Hashimoto's thyroiditis group. The difference in FT4 between the Graves disease group and the Hashimoto's thyroiditis group after 1 month of treatment and before treatment was (-28.47±10.09) and (-20.57±14.48) pmol/L ( t=7.01, P<0.001), and the difference of FT4 was (-47.06±20.57) and (-30.17±20.54) pmol/L ( t=3.91, P<0.001) between the Graves disease group and the Hashimoto toxin group. The difference between one month after treatment and before treatment was (-13.10(-34.10,-2.60)) and (-10.50(-27.5,-0.20)) cm/s ( Z=2.63, P=0.009), respectively. The difference between 3 months and before treatment was (-31.40(-53.20,-12.70)) and (-19.90(-46.00,-4.70)cm/s ( Z=4.40, P<0.001)) between the Graves disease group and the Hashimoto's thyroiditis group, and the difference was statistically significant. Conclusion:Thyroid hormone levels were decreased after treatment with methimazole in patients with diffuse toxic goiter and Hashimoto toxemia, but the difference was not statistically significant. The PSV level of superior thyroid artery in patients with diffuse toxic goiter was significantly lower than that in patients with Hashimoto's thyrotoxicosis.

Occupational silicosis (hereinafter referred to as "silicosis") exhibited individual differences in disease susceptibility, with genetic factors playing a crucial role in its onset and progression. Cytokines, such as interleukin (IL)-1RA +2018T>C locus, tumor necrosis factor-α -308G>A and -238G>A locus, transforming growth factor (TGF)-β1 +915G>C locus, were related to the development of silicosis. However, relationship between IL-17F +7488A>G and TGF-β1 -509T>C locus with silicosis had shown inconsistent results across different studies. Regulatory proteins such as matrix metalloproteinase (MMP)-2 -735C>T locus, MMP-9 rs3918242 locus, heat shock protein (HSP) 70-1+190G>C locus, carboxypeptidase M rs12812500 locus, family sequence similarity gene 13A (FAM13A) rs2609255 locus, and desmoplakin rs2076304 locus were also related to the development of silicosis. The A allele of the non-coding RNA miRNA-4508 rs6576457 increased the risk of developing silicosis-related pulmonary fibrosis in dust-exposed workers. The polymorphism in the long non-coding RNA ADGRG3 rs1814521 was related to silicosis susceptibility. Additionally, six circular RNAs of small nucleolar RNA host gene 14 rs17115143 sequence might be potential biomarkers of silicosis. Human leukocyte antigen-DR (HLA-DR) genes demonstrated a dual role in both risk and protection against silicosis, while angiotensin I-converting enzyme (ACE) gene polymorphisms likely affected silicosis development by modulating serum ACE activity. However, the mechanisms by which certain genetic variations affected susceptibility to silicosis remain unclear. Prospective studies with large-scale samples combining genetics, epidemiology, bioinformatics, and biofunctional studies are needed to promote the development of biomarkers for silicosis susceptibility and disease course, and clinical therapies.

Objective:To investigate the effects of miR200a and SIRT1 expression on epithelial cell apoptosis in age-related cataract lens epithelial cells.Methods:30 anterior capsule samples of age-related cataract patients were enrolled from the ophthalmology outpatient department of Beichen Hospital affiliated with Nankai University from January to August 2022 as the cataract group and another 30 normal anterior capsule samples of corneal transplantation were enrolled during the same period as the control group. Real -time fluorescence quantitative PCR (RT-qPCR) was used to detect the expression levels of miR200a and SIRT1 genes in the cataract group and control group. The oxidative stress level divided human lens epithelial cells SRA01/04 into a negative control group, miR200a overexpression group, and miR200a inhibition group. The negative control group, miR200a overexpression plasmid, and miR200a inhibitor group were transfected, respectively. Cell apoptosis rate and oxidative stress level were detected by flow cytometry, and Western Blot was used to detect the expression of SIRT1 protein and Caspase-3, Bcl-2, and Bcl-2 related X (Bax) proteins containing cysteine in each group of cells. The targeting relationship between miR200a and SIRT1 was validated using dual luciferase reporter gene detection. Results:Compared with the control group, the expression level of miR200a in the cataract group was significantly increased ( P < 0.01), while the expression level of SIRT1 was significantly reduced ( P < 0.01). Compared with the control group, the levels of SOD, GSH, and GSH-Px in the cataract group were significantly reduced (all P < 0.01), and the MDA level was significantly higher than those in the control group ( P < 0.01). The apoptosis rate of the miR200a overexpression group was significantly higher than that of the negative control group ( P < 0.05), and the apoptosis rate of the miR200a inhibition group was significantly lower than that of the negative control group, the differences were statistically significant ( P < 0.05). The level of SIRT1 protein in the miR200a overexpression group was significantly lower than that in the negative control group ( P < 0.05), and the level of SIRT1 protein in cells of the miR200a inhibition group was significantly higher than that of the negative control group ( P < 0.05). Compared with the negative control group, the miR200a overexpression group showed a significant increase in Caspase-3 activity and Bax protein (all P < 0.05), while the Bcl-2 protein level was significantly reduced ( P < 0.05). The miR200a inhibition group showed a significant decrease in Caspase-3 activity and Bax protein (all P < 0.05), while the Bcl-2 protein level was significantly increased ( P < 0.05). The dual luciferase experiment showed that the overexpression group of miR-200a can significantly inhibit the luciferase activity of the wild-type SIRT1 plasmid, which is the target gene of miR-200a. Conclusions:miR220a is highly expressed in the capsule of lens of patients with age-related cataracts, and its mechanism may be that miR220a promotes apoptosis of lens epithelial cells by targeting the expression of SIRT1.
