Background Amid global climate change, extreme environmental events are occurring more frequently, and it is imperative to investigate the impacts of combined exposure to fine particluate matter (PM2.5) and cold spells (CS) on population mortality. Objective To analyze the association between sequential extreme PM2.5-cold spell (EP-CS) events and non-accidental mortality among residents in Zigong City from 2016 to 2021. Methods Using time-series study design, meteorological data in Zigong were collected from the Zigong Meteorological Bureau for the period from January 1, 2016 to December 31, 2021, while daily non-accidental mortality data were obtained from the mortality surveillance system of the Zigong Center for Disease Control and Prevention. We adopted the percentile method to define extreme PM2.5 events and cold spells. We analyzed the risk effect of EP-CS events on non-accidental mortality among residents in this city and explored the potential amplification of damage resulting from different patterns of consecutive extreme events by using distributed lag nonlinear model (DLNM). We also conducted stratified analyses based on age, gender, education level, and marital status. Results The EP-CS events demonstrated a significant impact on non-accidental mortality among the local residents, exhibiting a certain lagged effect. The effects on the overall residents lasted from lag0 (RR=1.030, 95%CI: 1.013, 1.048) to lag14 (RR=1.035, 95%CI: 1.019, 1.052). Notably, the effects were more pronounced among females, individuals aged 65 years and above, and those who were never married, divorced, or widowed. Different patterns of EP-CS events all associated with adverse effects, the health impact of EP-CS events was significantly greater than that of individual PM2.5 pollution or CS events. The analysis of lag effects across different event patterns revealed that the overall effect of EP-CS events with shorter intervals (0–7 d) had a stronger effect compared to EP-CS with longer intervals (8–14 d), and the RR values of lag14 were 1.034 (95%CI: 1.015, 1.054) and 1.017 (95%CI: 1.007, 1.027), suggesting that the damaging effect of compound events occurring in the short term was more significant. Conclusion All sequential extreme EP-CS events have an impact on non-accidental mortality among residents in this city, with compound events demonstrating a stronger effect. Females, individuals aged ≥65 years, and those who were never married, divorced, or widowed are more sensitive to EP-CS events.

Objective:To investigate the impact of geometric morphology and hemodynamic characteristics at the carotid bifurcation on the formation of ulcerated plaques based on CT angiography(CTA).Methods:This was a cross-sectional study. The clinical and imaging data of 71 patients with carotid bifurcation atherosclerotic plaques (stenosis≥50%) confirmed by cranial and cervical CTA at Tianjin TEDA Hospital from July 2020 to October 2023 were retrospectively analyzed. Patients were divided into an ulcerated plaque group (32 cases) and a non-ulcerated plaque group (39 cases) based on plaque ulceration status. The CTA technique was used to assess the geometric parameters of the carotid bifurcation [such as the bifurcation angle, the angle between the common carotid artery and internal carotid artery (CCA-ICA), the proximal curvature angle of the internal carotid artery (ICA), and the ratio of the maximum area at the carotid bifurcation to the initial area of the carotid artery (CCAMAX/CCA)] and plaque characteristic parameters [such as plaque area at the site of stenosis, maximum wall thickness, remodeling ratio, eccentricity index, and presence of calcification within plaques]. Quantitative analysis of hemodynamic parameters in the plaque region was performed using finite-element analysis software, including time-averaged wall shear stress (TAWSS), transverse wall shear stress (transWSS), relative residence time (RRT), and oscillatory shear index (OSI). Comparisons of parameters between the two groups were conducted using the Mann-Whitney U test or χ2 test, and multivariate logistic regression analysis was employed to identify independent geometric and plaque characteristic factors influencing the formation of ulcerated plaques. A combined model incorporating hemodynamic, geometric, and plaque characteristic parameters was developed, and the efficacy of this combined model in predicting ulceration formation at the carotid bifurcation was evaluated using receiver operating characteristic curves and the area under the curve (AUC). Results:The bifurcation angle, CCA-ICA angle, proximal ICA curvature angle, CCAMAX/CCA ratio, presence of calcification within plaques, plaque area at the site of stenosis, and maximum wall thickness exhibited statistically significant differences between the ulcerated plaque group and the non-ulcerated plaque group ( P<0.05). Logistic regression analysis showed that CCAMAX/CCA ( OR=6.452, 95% CI 1.541-27.015, P=0.011) and plaque area at the site of stenosis ( OR=1.048, 95% CI 1.015-1.124, P=0.011) were independent factors influencing the formation of ulcerated plaques at the carotid bifurcation. The maximum and mean values of RRT and OSI in the ulcerated plaque group were significantly higher than those in the non-ulcerated group ( P<0.05), while the maximum and mean values of transWSS and TAWSS were lower in the ulcerated group compared to the non-ulcerated group ( P<0.05). The AUC for the combined model predicting ulceration formation at the carotid bifurcation was 0.926. Conclusions:The CCAMAX/CCA ratio and plaque area at the site of stenosis at the carotid bifurcation are independent factors influencing the formation of ulcerated plaques. A model that combines geometric morphology and hemodynamic parameters can more effectively diagnose the formation of ulcerated plaques at the carotid bifurcation.

Objective To analyze the disease burden of chronic kidney diseases (CKD) attributed to high body mass index (BMI) in China from 1992 to 2021 and predict the disease burden for the next decade, and to provide evidence for the prevention and treatment of CKD. Methods Using the Global Burden of Disease (GBD) database and the Joinpoint model, the average annual percentage rate change (AAPC) of the mortality rate and disability-adjusted life year (DALY) rate was calculated to describe and analyze the CKD disease burden attributed to high BMI in China from 1992 to 2021. The ARIMA model was employed to predict and analyze the change trend of the CKD disease burden. Results From 1992 to 2021, the mortality rate and DALY rate attributed to high BMI-induced chronic kidney disease showed an upward trend. Compared to 1992, the attributed number of deaths increased by 324.38%, and DALYs increased by 268.56%; the mortality rate increased by 64.00%, and the DALY rate grew by 51.62%. From 1992 to 2021, the mortality rate and DALY rate for males were lower than those for females, but the growth rate for males exceeded that of females. From 1992 to 2021, the mortality rate and DALY rate of chronic kidney disease attributed to high BMI in China increased with age. The average annual change rate of chronic kidney disease attributed to high BMI in China from 1992 to 2021 (mortality rate: 1.40 per 100,000 (95% CI: 1.04–1.76), DALY rate: 1.43 per 100 000 (95% CI: 1.17–1.70)) was higher than thHuaiyin Normal University, Huai'anher social demographic index (SDI) regions. The ARIMA model predicted that the age-standardized mortality rate increased from 2.91 per 100 000 in 2022 to 3.05 per 100 000 in 2026, and the age-standardized DALY rate increased from 69.65 per 100 000 in 2022 to 73.58 per 100 000 in 2026. Conclusion Chronic kidney disease attributed to high BMI in China is on the rise, and it will continue to grow in the future. The focus of CKD prevention and control should be on males and the elderly, while active measures should be taken to reduce the occurrence and progression of chronic kidney disease.

Objective:
To investigate the efficacy, safety, and traditional Chinese medicine (TCM) medication patterns of rituximab (RTX) combined with TCM on treating children with steroid-dependent nephrotic syndrome (SDNS).
Methods:
One hundred and forty-three children with SDNS who visited the Pediatric Nephrology Department of the First Affiliated Hospital of Henan University of Chinese Medicine from January 2018 to December 2022 were enrolled. A cohort study design was adopted, with " RTX treatment" as the exposure factor. Children who met this exposure factor were assigned to the RTX cohort (RTX, glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment), whereas those who did not were assigned to the basic treatment cohort (glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment ), and followed up for 6 months. The frequency of urinary protein recurrences, urinary protein remission duration, proportion and duration of steroid reduction and cessation, cumulative usage of steroids, proportion of recurrence, recurrence amount of steroid used, efficacy of TCM syndrome, and laboratory and safety indicators after treatment, and height and CD19+ B cell count before and after treatment were compared between the two cohorts. The medication patterns of TCM in the two cohorts were analyzed using frequency statistics, association rule analysis, and systematic clustering analysis.
Results:
Compared with the basic treatment cohort, the RTX cohort showed a decrease in the frequency of urinary protein recurrence, extended sustained remission of urinary protein, an increase in the proportion of steroid reduction and cessation, a shorter duration of steroid reduction and cessation, a decrease in cumulative steroid dosage, a lower recurrence rate, a decrease in CD19+ B cell count, and a decrease in 24-h urinary total protein quantification and the level of cholesterol (P<0.05). No significant difference in the recurrence amount of steroid used, height, TCM syndrome efficacy, albumin, aspartate transaminase, blood urea nitrogen, platelet count, and safety indicators between the two cohorts. Children with SDNS were mostly characterized by qi and yin deficiency syndrome, followed by spleen and kidney yang deficiency syndrome. A total of 175 TCMs were included, including 28 high-frequency drugs such as Huangqi, Fuling, Gancao, Baizhu, Dangshen, and Jiuyurou. The primary use of medication is to nourish the qi and spleen, nourish the kidney, and warm yang. The analysis of association rules yielded eight binary associations and ten three-phase associations, with Huangqi, Baizhu, Fuling, and Dangshen, being the most closely related. Cluster analysis identified four TCM combinations, primarily focusing on tonifying kidney and replenishing essence, benefiting qi and nourishing yin, and removing blood stasis.
Conclusion
RTX combined with TCM syndrome differentiation treatment can reduce the recurrence frequency of SDNS, prolong the remission period, reduce the glucocorticoid dosage, and have no marked effect on height growth. No apparent adverse reactions were observed. TCM should focus on nourishing qi and yin while removing blood stasis.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Tripterygium wilfordii multiglucoside,the primary active constituent of the Chinese materia medica of Tripterygium wilfordii,has anti-inflammatory and immune-regulation properties and is widely used to treat kidney and rheumatic and immunological diseases.However,the potential adverse effects of Tripterygium wilfordii multiglucoside on pediatric gonadal development have limited its clinical application in pediatrics.According to the traditional Chinese medicine theory,the reproductive toxicity of Tripterygium wilfordii is closely associated with deficiency in kidney essence and tian gui disorder.Based on the"kidney essence-tian gui"theory,this study elucidates the transformation of"kidney essence to tian gui"through the qi transformation of"original noumenon to supreme ultimate,"which is synergistically regulated by the accumulation of kidney qi,consolidation of spleen qi,and conveyance and dispersion of liver qi.It is channeled through the interconnected pathways of the thoroughfare channel,conception channel,and governor channel.The physiological process of"kidney essence to tian gui"is damaged by the bitter,cold,and toxicity of Tripterygium wilfordii,leading to kidney asthenia,spleen deficiency,liver depression,and meridian stagnation,causing tian gui dysregulation.Therefore,this study offers traditional Chinese medicine prevention and treatment strategies for pediatric medication safety,including nourishing the kidney essence to replenish the tian gui source,enhancing the middle jiao to strengthen the tian gui guard,regulating liver qi to promote the operation of tian gui,and unblocking the thoroughfare channel,conception channel,and governor channel to ensure the unobstructed pathway of tian gui.
