Objective To explore the association between meteorological factors and suicide in cancer patients. Methods Based on the Shandong Multicenter Healthcare Big Data Platform, data on suicide deaths of cancer patients were collected from January 2010 to December 2021. Meteorological data were extracted for the corresponding time. Conditional logistic regression models were constructed using case-crossover design to explore the association between meteorological factors and suicide risk. Results A total of 80 patients with cancer suicide deaths were included, including 48 males, 32 females, and 43 patients aged 60 and above. Suicide risk in cancer patients increased with increasing monthly average temperatures, with an OR of 1.20 (95% CI: 1.12 - 1.28). The ORs for monthly average maximum and minimum temperatures were 1.20 (95% CI: 1.13 - 1.29) and 1.19 (95% CI: 1.12 - 1.27), respectively. Monthly average sunshine duration and monthly average precipitation were negatively associated with the risk of suicide in cancer patients. However, no associations were observed on daily and weekly scales. In all subgroups, the increase in monthly mean temperature, monthly mean minimum temperature, and monthly mean maximum temperature was associated with the increased suicide risk of cancer patients. The risk of suicide among males, females and cancer patients ≥ 60 years were affected by monthly mean sunshine duration, while cancer patients < 60 years were more susceptible to the influence of monthly mean precipitation. Conclusion The meteorological factors are highly related to the risk of suicide in cancer patients, and psychological interventions for cancer patients during weather changes should be strengthened to reduce their suicide risk.

Objective:To evaluate the prognosis of Hall technique and traditional performed metal crown (PMC) restoration technique, and to follow up the occlusal changes before and after treatment with Hall technique, providing references for the promotion of Hall technique.Methods:Children who visited the Department of Pediatric Dentistry, West China Hospital of Stomatology, Sichuan University from May 2021 to December 2022 were screened according to the inclusion and exclusion criteria. The therapeutic effects of the two groups were followed up at three time points: 1, 2 and 3 months after operation. The observation results were divided into three outcomes: success (crown in place, no symptoms of pulpitis or periapical periodontitis, no obvious abnormality in occlusion, no need for further treatment), partial failure (crown falling off or crown broken, tooth defect can be repaired, reversible pulpitis) and complete failure (irreversible pulpitis or periapical periodontitis, crown falling off and tooth defect irreparable), and statistical analysis was made. At the same time, the Hall technique group was followed up at five time points as before operation, immediately after operation, 2 weeks after operation, 4 weeks after operation and 8 weeks after operation respectively, in which the occlusion was analyzed by Dental Prescale Ⅱ system. The vertical dimension of occlusion (VDO), overbite and coverage, and canine relationship were recorded and compared. Three-dimensional finite element method was used to model and analyze the stress of the teeth treated with traditional PMC treatment and Hall technique, and the differences between them were compared.Results:Finally, 21 children were included in the Hall technique group, including 12 boys and 9 girls, with age of (5.0±1.4) years. Meanwhile, 22 children including 15 boys and 7 girls were in the traditional PMC group, with age of (5.1±1.3) years. There were 0 cases of complete failure and 0 cases of partial failure both in the Hall technique group and in the traditional PMC group within 1 month. There were 0 cases of complete failure and 1 case of partial failure in the Hall technique group, while 0 cases of complete failure and 0 cases of partial failure in the traditional PMC group within 2 months after operation. Hall technique group failed completely in 1 case and partially in 1 case, while the traditional pre-crown group failed completely in 0 cases and partially in 0 cases 3 months after operation. There was no significant difference in the incidence of primary index/complete failure and secondary index/partial failure between Hall technique group and traditional PMC group (all P>0.05). The occlusal area and occlusal force of children treated with Hall technique decreased immediately after operation compared with those before operation, but gradually recovered to the preoperative level at 2, 4 and 8 weeks after operation. To elaborate, the occlusal area decreased significantly from (14.79±3.55) mm 2 before operation to (10.15±3.17) mm 2 immediately after operation ( P=0.001), and recovered to (15.58±3.39) mm 2 at 8 weeks after operation ( P>0.05 compared with pre-operation). The occlusal force decreased significantly from (436.94±109.59) N before operation to (292.70±96.05) N immediately after operation ( P=0.001), and recovered to (441.86±104.31) N at 8 weeks after operation ( P>0.05 compared with pre-operation). Overbite decreased significantly from (2.54±1.05) mm before operation to (1.80±0.94) mm immediately after operation ( P=0.044) and then recovered to (2.35±1.02) mm ( P>0.05 compared with pre-operation). The coverage changed from (2.41±0.66) mm before operation to (2.27±0.61) mm immediately after operation ( P>0.05) and then recovered to (2.48±0.62) mm ( P>0.05 compared with pre-operation). The canine relationship was (3.12±0.54) mm before operation, and decreased significantly immediately after operation (2.17±0.89) mm ( P=0.001), and recovered to (3.05±0.61) mm after 8 weeks ( P>0.05 compared with pre-operation). In the three-dimensional finite element analysis, the maximum stress of all parts of the affected tooth increased immediately after Hall technique treatment, but with occlusal adjustment, the maximum stress of all parts of the affected tooth decreased, which was similar to that of the traditional metal pre-crown group. The vertical load and oblique load of pre-crown decreased from 180.11 and 496.16 MPa to 108.05 and 297.69 MPa, respectively. The vertical load and oblique load of enamel decreased from 94.83 and 255.94 MPa to 57.21 and 156.44 MPa, respectively. The vertical load and oblique load of dentin decreased from 55.19 and 124.77 MPa to 33.19 and 74.59 MPa, respectively. Conclusions:During the experimental observation period, there is no obvious difference between Hall technique and traditional PMC treatment technology in terms of post-treatment occlusion and clinical prognosis, which supports clinical application.

Objective To investigate the influencing factors associated with the comorbidity of inflammatory bowel disease (IBD) and depression. Methods A case-control study was conducted based on the ^“Healthcare Big Data Platform^” of a tertiary class-A comprehensive hospital in Shandong Province. IBD comorbid with depression was served as the case group and IBD without depression was served as the control group. Propensity score matching (PSM) was performed by matching the case group with the control group in a ratio of 1:2 according to the age and gender of the patients. Conditional logistic regression model was used to explore the influencing factors associated with the comorbidity of IBD and depression. Results A total of 405 patients with IBD were enrolled in this study, including 270 patients without depression and 135 patients comorbid with depression. The results of conditional logistic regression showed that the use of immunosuppressants (OR=2.84, 95% CI: 1.00-8.07) and glucocorticoids (OR=2.05, 95% CI: 1.17-3.58), dementia (OR=5.20, 95% CI:1.59-17.05), cardiovascular disease (OR=3.58, 95% CI: 1.84-6.98) and cancer (OR=2.63, 95% CI: 1.16-5.95) were associated with the comorbidity of depression and IBD. Conclusion Attention should be paid to the use of immunosuppressants and glucocorticoids in the population of IBD comorbid with depression, and the coexistence of physical diseases such as dementia, cardiovascular disease and cancer. Early prevention and targeted treatment measures should be taken for high-risk populations to reduce their risk of depression and improve their quality of life and health.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

Bombesin receptor subtype-3 (BRS3) is an orphan G protein-coupled receptor (GPCR) that plays critical roles in energy homeostasis, glucose metabolism, and insulin secretion. Recent structural studies have elucidated BRS3 signaling mechanisms using synthetic ligands, including BA1 and MK-5046. However, the molecular basis of BRS3 activation by bioactive natural compounds and their derivatives, particularly those derived from traditional Chinese medicine, remains unclear. Here, we present high-resolution cryogenic electron microscopy (cryo-EM) structures of the human BRS3-G_q complex in both unliganded and active states bound by two herb-derived compounds (DSO-5a and oridonin), at resolutions of 2.9, 2.8, and 2.9 Å, respectively. These structures display distinct ligand recognition patterns between DSO-5a and oridonin. Although both compounds bind to the orthosteric pocket, they differentially engage the interaction network of BRS3, as demonstrated by mutagenesis studies assessing calcium mobilization and inositol phosphate 1 (IP1) accumulation. These findings enhance our understanding of BRS3 activation and provide valuable insights into the development of small-molecule BRS3 modulators with therapeutic potential.

Objective To investigate the renal function recovery and perioperative risk factors for chronic kidney disease in patients after acute Stanford type A aortic dissection (ATAAD) repair. Methods A retrospective study was conducted on patients who underwent ATAAD repair at the Xiamen Cardiovascular Hospital, Xiamen University from 2020 to 2021, and their clinical data were analyzed. Results A total of 255 patients were included, with 200 males and 55 females, and an average age of (52.80±12.46) years. The incidence of acute kidney injury (AKI) after ATAAD repair was 43.9%. Dissection involving the renal artery [OR=2.144, 95%CI (1.234, 3.765), P=0.007], intraoperative urine output [OR=0.761, 95%CI (0.625, 0.911), P=0.004], and intraoperative red blood cell transfusion [OR=1.288, 95%CI (1.088, 1.543), P=0.004] were significantly associated with early AKI after ATAAD repair. Long-term renal function follow-up data were available for 232 patients, among whom 40 (17.2%) patients developed chronic kidney disease (CKD). Independent predictors for CKD included lower body mass index [OR=0.827, 95%CI (0.723, 0.931), P=0.003], preoperative cardiac tamponade [OR=5.344, 95%CI (1.65, 17.958), P=0.005], preoperative renal hypoperfusion syndrome [OR=12.629, 95%CI (5.003, 35.373), P<0.001], postoperative peak serum creatinine time>3 d [OR=7.566, 95%CI (2.799, 22.731), P<0.001], and AKI grade [grade 1: OR=4.418, 95%CI (1.339, 15.361), P=0.016; grade 2: OR=8.345, 95%CI (1.762, 40.499), P=0.007; grade 3: OR=9.463, 95%CI (2.602, 37.693), P<0.001]. Conclusion AKI related to ATAAD repair can recover in the early postoperative period, but both the duration and severity of AKI will affect long-term renal function. In addition, patients' nutritional status, preoperative cardiac tamponade, and renal hypoperfusion syndrome are also independent risk factors for long-term renal dysfunction.

Objective To analyze the publication profile and research hotspots of studies at home and abroad on postoperative cognitive dysfunction by bibliometric methods. Methods Literatures related to postoperative cognitive dysfunction published in the China National Knowledge Infrastructure (CNKI) and Web of Science databases from 2013 to 2023 were included, and statistical analysis was conducted by CiteSpace software. Results A total of 2 705 Chinese literatures and 2 412 English core literatures were included. The number of literatures on postoperative cognitive dysfunction showed an annual increase from 2013 to 2023; China was the country with the highest number of publications internationally, with Capital Medical University ranking the top among Chinese institutions; domestically, postoperative cognitive dysfunction researches predominantly focused on clinical studies, while overseas researches emphasized pathological mechanisms and basic investigations. Research hotspot analysis revealed an enhanced interest in the inflammatory mechanisms and anesthetic aspects of postoperative cognitive dysfunction. Conclusion From 2013 to 2023, the overall research at home and abroad interest in postoperative cognitive dysfunction has shown an upward trend, yet its pathophysiological mechanisms need further exploration. The risk factors for postoperative cognitive impairment and their correlations with anesthesia and mortality are being actively explored, and new methods for prevention and treatment such as percutaneous electrical stimulation are gradually emerging.

Objective:To investigate the correlation between gender, age, blood collection time, season and changes in cTnT concentration.Methods:In this study, 3548 patients (non-cardiovascular diseases) in Zhongshan Hospital of Fudan University were selected from 1 January to 31 December 2019. The basic data of the patients were collected, including gender, age, time of blood collection, medical history, clinical diagnosis, and results of cTnT testing. 1 840 males and 1 708 females were finally enrolled, with an age distribution of 65 (53, 75) years. The distribution of the data was assessed using the Kolmogorov-Smirnov (K-S) test, where non-normally distributed data were expressed as M( Q1, Q3). The Mann-Whitney U-test was used to compare cTnT concentrations between men and women, and to analyse the influence of gender on cTnT results. The Kruskal-Wallis test was used to compare cTnT levels between gender groups, to analyse the correlation between different times of blood collection, seasons, and other factors and cTnT concentrations. Result:cTnT concentrations increased with age in both males and females over the age of 60 years. cTnT levels were highest in individuals over the age of 90 years (0.028 ng/ml in males and 0.018 ng/ml in females). cTnT levels were higher in males (0.012 ng/ml) than in females (0.009 ng/ml) in all age groups ( H=6.340, P<0.01). The concentrations of cTnT varied at different time points of blood collection. In both males and females, cTnT concentrations reached a maximum at 8:00 and 13:00 (0.013 ng/ml and 0.012 ng/ml, respectively). Analysis of the physiological effect of season on cTnT secretion showed that cTnT levels were generally higher in spring and winter(0.012 ng/ml) than in summer and autumn(0.010 ng/ml). Conclusions:cTnT concentration is influenced by gender, age, time of blood collection and season. When analysing cTnT results in clinical practice, the gender and age of the individual should be taken into account, as well as the time point of blood collection and seasonal factors.

Objective:To explore the differences of gene expression profiles of precursors of exhausted T cells (Tpex) and terminal exhausted T cells (Tex) in the peripheral blood of patients with active pulmonary tuberculosis (ATB).Methods:Twenty-five cases of ATB, 13 cases of latent tuberculosis infection (LTBI) and 10 health controls were enrolled from January 2021 to October 2022 in the Fifth People′s Hospital of Wuxi. The proportions of Tpex and Tex in the peripheral blood mononuclear cells (PBMCs) of the three groups were detected by flowcytometry. PBMCs of ATB were separated into Tpex and Tex by fluorescence-activated cell sorting. RNA-sequencing was performed and up-regulated and down-regulated genes were screended. Differently expressed genes were analyzed by gene set enrichment analysis of gene ontology (GO) to find regulatory pathways affecting cell metabolism and function. Wilcoxon matched-pairs signed rank test, Kruskal-Wallis test and Dunn multiple comparsion test were used for statistical analysis.Results:The proportion of Tpex in ATB group was 2.86%(1.74%), which was lower than 7.93%(6.16%) of Tex, and the difference was statistically significant ( Z=-3.91, P<0.001). The proportions of Tpex and Tex in LTBI group were 9.47%(6.26%) and 7.43%(5.48%), respectively, and the difference was not statistically significant ( Z=-0.93, P=0.345). The proportions of Tpex and Tex in healthy control group were 8.42%(2.69%) and 6.49%(5.14%), respectively, with no statistical significance ( Z=-1.36, P=0.170). There was statistical difference of the proportion of Tpex among the three groups ( H=21.93, P<0.001), and the proportion of Tpex in ATB group was lower than those in LTBI and heathy control groups, and the differences were both statistically significant ( Z=4.16, P<0.001 and Z=3.34, P=0.003, respectively), while the proportions of Tex in these three groups were not statistically different ( H=2.17, P=0.338). Compared with Tex, the gene expressions of memory markers, such as B-cell lymphoma 2 of Tpex were up-regulated, and the gene expressions of exhausted markers, such as lymphocyte activation gene 3 were down-regulated. In terms of cellular metabolism, the gene expressions of mitochondrial protein complex, mitochondrial matrix and oxidative phosphorylation of Tpex were up-regulated, and the gene expressions of glycolysis were down-regulated. The gene expressions of pyruvate metabolism in Tex were up-regulated, and the gene expressions of CD4 + T lymphocyte activation and differentiation and glycolytic process in Tpex were down-regulated. Conclusions:Tpex in ATB express more characteristics of memory cells and less features of exhausted markers compared with Tex, and the function of mitochondria of Tpex preserves well.
