Objective To analyze the epidemiological characteristics and prognostic factors of acute cardiovascular and cerebrovascular events in Jianyang City from 2020 to 2023. Methods Medical records of acute cardiovascular and cerebrovascular disease patients treated in three hospitals in Jianyang City from January 2020 to December 2023 were selected, and their epidemiological characteristics were analyzed. Multivariate logistic regression was used to analyze the risk factors for mortality. Results From 2020 to 2023, 23000 cases of acute cardiovascular and cerebrovascular events were reported in Jianyang City, with a standardized incidence rate of 508.76/100 000 and a gender ratio of 1.33:1. All diseases and the total standardized incidence rate of men are higher than those of women; ≥ The total incidence rate and all incidence rate of the 85 year old group are the highest; The incidence rate is the highest in 2021, and the incidence rate is the highest in spring and winter. The standardized mortality rate of acute cardiovascular and cerebrovascular events was 108.08/100 000, with significant differences among different ages, disease types, and onset seasons (P<0.05). Multivariate analysis showed that age, onset season, and disease type were independent risk factors for patient mortality (P<0.05). Conclusion From 2020 to 2023, the standardized incidence rate of acute cardiovascular and cerebrovascular events in Jianyang City is higher, which is more common in the elderly population. The risk of men is higher than that of women, and the risk is higher in spring and winter. Age, disease type, and onset season are all directly related to the risk of death. In the future, it is necessary to strengthen the monitoring and prevention of cardiovascular and cerebrovascular diseases, and optimize emergency treatment work in order to improve patient prognosis.

Objective:To analyze the treatment efficacy, safety and dose parameters of optimized hippocampus-avoidance prophylactic cranial irradiation (HA-PCI) in limited-stage small cell lung cancer (LS-SCLC) and explore the corresponding dosimetric parameters under the condition of narrowing the hippocampus avoidance region as hippocampus region plus 2 mm in three dimensions.Methods:Clinical data of patients with LS-SCLC receiving HA-PCI (hippocampus avoidance region defined as hippocampus region plus 2 mm in three dimensions) in Cancer Hospital Chinese Academy of Medical Sciences from August 2014 to June 2020 were retrospectively analyzed. Dose parameters of HA-PCI and adverse events were analyzed using descriptive statistics analysis. Changes of neurocognitive function, such as mini-mental state examination (MMSE) and Hopkins verbal learning test-revised (HVLT-R) scores, were evaluated by analysis of variance and Kruskal-Wallis H test. Overall survival (OS), progression-free survival (PFS) and intracranial PFS (iPFS) were calculated using Kaplan-Meier method. The cumulative incidence of local-regional recurrence (LRR), extracranial distant metastases (EDM), and locoregional recurrence (LR) were investigated under competing risk analysis. Results:A total of 112 patients were included, the median follow-up time was 50 months (95% CI: 45.61-54.38). The median volume of hippocampus was 4.85 ml (range: 2.65-8.34 ml), with the average dose ≤9 Gy in 106 patients (94.6%), ≤8 Gy in 92 patients (82.1%). The median volume of hippocampus avoidance area was 15.00 ml (range: 8.61-28.06 ml), with the average dose ≤12 Gy in 109 patients (97.3%), ≤10 Gy in 101 patients (90.2%). The 2-year cumulative LRR, EDM, LR rates were 16.9%, 23.2% and 28.5%, respectively. The 5-year cumulative LRR, EDM, LR rates were 23.2%, 26.9% and 33.3%, respectively. The 2-year iPFS, PFS and OS rates were 66.1% (95% CI: 57.9%-75.4%), 53.6% (95% CI: 45.1%-63.7%) and 80.4% (95% CI: 73.3%-88.1%), respectively. The most common grade I-Ⅱ adverse events were nausea (33.9%) and dizziness (31.3%), and only 1 patient developed grade Ⅲ nausea and dizziness. MMSE ( n=57) and HVLT-R tests ( n=56) showed no significant decline. Conclusions:Optimized HA-PCI can achieve similar dose limitation with favorable efficacy and light toxicity. No significant decline is observed in short-term neurocognitive function in evaluable patients.

Background::The disease burdens for endometrial cancer (EC) vary across different countries and geographical regions and change every year. Herein, we reported the updated results of the Global Burden of Disease Study 2019 on EC with respect to age-standardized incidence and mortality from 1990 to 2019.Methods::The annual percentage change (APC) of incidence and mortality was evaluated using joinpoint regression analysis to examine the temporal trends during the same timeframe in terms of the global landscape, different sociodemographic indices (SDI), and geographic regions. The relationship between Human Development Index (HDI) and incidence and mortality was additionally explored.Results::The age-standardized incidence rates (ASIRs) revealed a significant average global elevation by 0.5% per year (95% confidence interval [CI], 0.3–0.7; P <0.001). The age-standardized mortality rates (ASMRs), in contrast, fell by an average of 0.8% per year (95% CI, ?1.0 to ?0.7; P <0.001) worldwide. The ASIRs and ASMRs for EC varied across different SDIs and geographical regions. We noted four temporal trends and a significant reduction by 0.5% per year since 2010 in the ASIR, whereas we detected six consecutively decreasing temporal trends in ASMR during the entire period. Notably, the estimated APCs were significantly positively correlated with HDIs (ρ = 0.22; 95% CI, 0.07–0.35; P = 0.003) with regard to incident cases in 2019. Conclusions::Incidence rates for EC reflected a significant increase overall (although we observed a decline since 2010), and the death rates declined consecutively from 1990 to 2019. We posit that more precise strategies can be tailored and then implemented based on the distinct age-standardized incidence and mortality burden in different geographical areas.

OBJECTIVES: This study aimed to investigate how naringenin (Nar) affected the anti-inflammatory, vascula-rization, and osteogenesis differentiation of human periodontal ligament stem cells (hPDLSCs) stimulated by lipopolysaccharide (LPS) and to preliminarily explore the underlying mechanism. METHODS: Cell-counting kit-8 (CCK8), cell scratch test, and Transwell assay were used to investigate the proliferation and migratory capabilities of hPDLSCs. Alkaline phosphatase (ALP) staining, alizarin red staining, lumen-formation assay, enzyme-linked immunosorbent assay, quantitative timed polymerase chain reaction, and Western blot were used to measure the expression of osteopontin (OPN), Runt-related transcription factor 2 (RUNX2), vascular endothlial growth factor (VEGF), basic fibroblast growth factor (bFGF), von Willebrand factor (vWF), tumor necrosis factor-α (TNF-α), and interleukin (IL)-6. RESULTS: We observed that 10 μmol/L Nar could attenuate the inflammatory response of hPDLSCs stimulated by 10 μg/mL LPS and promoted their proliferation, migration, and vascularization differentiation. Furthermore, 0.1 μmol/L Nar could effectively restore the osteogenic differentiation of inflammatory hPDLSCs. The effects of Nar's anti-inflammatory and promotion of osteogenic differentiation significantly decreased and inflammatory vascularization differentiation increased after adding AMD3100 (a specific CXCR4 inhibitor). CONCLUSIONS Nar demonstrated the ability to promote the anti-inflammatory, vascularization, and osteogenic effects of hPDLSCs stimulated by LPS, and the ability was associated with the stromal cell-derived factor/C-X-C motif chemokine receptor 4 signaling axis.

Objective:To investigate the safety and feasibility of the CHESS endoscpic ruler (CHESS ruler), and the consistency between the measured values and the interpretation values by endoscopic physician experience.Methods:From January 2021 to January 2022, a total of 105 liver cirrhosis patients with portal hypertension were prospectively enrolled from General Hospital, Xixia Branch Hospital, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region (29 cases), and the First People′s Hospital of Yinchuan (25 cases), General Hospital of Ningxia Medical University (18 cases), Wuzhong People′s Hospital (10 cases), the Fifth People′s Hospital of Ningxia Hui Autonomous Region (10 cases), Shizuishan Second People′s Hospital (6 cases), Yinchuan Second People′s Hospital (5 cases), and Zhongwei People′s Hospital (2 cases) 8 hospitals. The clinical characteristics of all the patients, including gender, age, nationality, etiolog of liver cirrhosis, and Child-Pugh classification of liver function were recorded. A big gastroesophageal varices was defined as diameter of varices ≥5 mm. Endoscopist (associated chief physician) performed gastroscopy according to the routine gastroscopy procedures, and the diameter of the biggest esophageal varices was measured by experience and images were collected, and then objective measurement was with the CHESS ruler and images were collected. The diameter of esophageal varices of 10 randomly selected patients (random number table method) was determined by 6 endoscopists (attending physician or associated chief physician) with experience or measured by CHESS ruler. Kappa test was used to test the consistency in the diameter of esophageal varices between measured values by CHESS ruler and the interpretation values by endoscopic physician experience.Results:Among 105 liver cirrhosis patients with portal hypertension, male 65 cases and female 40 cases, aged (54.8±12.2) years old, Han nationality 82 cases, Hui nationality 21 cases and Mongolian nationality 2 cases. The etiology of liver cirrhosis included chronic hepatitis B (79 cases), alcoholic liver disease (7 cases), autoimmune hepatitis (7 cases), chronic hepatitis C (2 cases), and other etiology (10 cases). Liver function of 32 cases was Child-Pugh A, Child-Pugh B 57 cases, and Child-Pugh C 16 cases. All 105 liver cirrhosis patients with cirrhotic portal hypertension were successfully measured the diameter of gastroesophageal varices by CHESS ruler, and the success rate of application of CHESS ruler was 100.0% (105/105). The procedure time from the CHESS ruler into the body to the exit of the body after measurement was (3.50±2.55) min. No complications happened in all the patients during measurement. Among 105 liver cirrhosis patients with cirrhotic portal hypertension, 96 cases (91.4%) were recognized as big gastroesophageal varices by the endoscopists. Totally 93 cases (88.6%) were considered as big gastroesophageal varices by CHESS ruler. Eight cases were recognized as big gastroesophageal varices by the endoscopist, however not by the CHESS ruler; 5 cases were recognized as big gastroesophageal varices by the CHESS ruler, but not by the endoscopists; 4 cases were not recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler; 88 cases were recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler. The missed diagnostic rate of big gastroesophageal varices by the endoscopists experience was 5.4% (5/93), and the Kappa value of consistency coefficient between the measurement by the CHESS ruler and the interpretation by endoscopists experience was 0.31 (95% confidence interval 0.03 to 0.60). The overall Kappa value of consistency coefficient by 6 endoscopists measured by CHESS ruler in big gastroesophageal varices diagnosis was 0.77 (95% confidence interval 0.61 to 0.93).Conclusion:As an objective measurement tool, CHESS ruler can make up for the deficiency of subjective judgment by endoscopists, accurately measure the diameter of gastroesophageal varices, and is highly feasible and safe.

Objective:To evaluate the efficacy and safety of hippocampal avoidance whole-brain irradiation with simultaneous integrated boost in the treatment of brain metastases of lung cancer.Methods:Forty lung cancer patients with brain metastases who received whole-brain radiotherapy with simultaneous integrated boost and hippocampal avoidance in Cancer Hospital, Chinese Academy of Medical Sciences from 2014 to 2020 were enrolled in this study. Brain MRI, survival follow-up and evaluation of side effects were performed before radiotherapy and at 1, 3, 6 and 12 months after radiotherapy, respectively. Overall survival (OS), progression-free survival (PFS) and changes in cognitive function were analyzed. Continuous data were described as Mean ± SD. Categorical data were described by frequency and composition ratio or percentage. Survival analysis was conducted by Kaplan-Meier method. Influencing factors of survival were identified by univariate and multivariate Cox's regression analyses.Results:A total of 40 patients were enrolled in the study. The median follow-up time was 14.2 months and the median OS, PFS and intracranial PFS of all patients were 14.8 months, 6.7 months and 14.8 months, respectively. Multivariate analysis showed that male gender and newly diagnosed stage Ⅳ disease were associated with worse OS and PFS, respectively. The Hopkins verbal learning test-revised (HVLT-R) scores at baseline and 1, 3 and 6 months after radiotherapy were 21.94±2.99, 20.88±3.12, 20.03±3.14, and 19.78±2.98, respectively. The HVLT-R score at 6 months after radiotherapy was decreased by approximately 9.8% compared with the baseline. No grade 3 or above toxic and side effect occurred in the entire cohort.Conclusion:Hippocampal avoidance whole-brain irradiation with simultaneous integrated boost is a safe and effective treatment for brain metastases of lung cancer, which is expected to reduce the impact of radiotherapy on cognitive function.

AIM: To investigate the relationship between the levels of chemokine receptor 2(CXCR2)and basic fibroblast growth factor(bFGF)in aqueous humor and the prognosis of trabeculectomy in patients with acute primary angle-closure glaucoma(APACG).METHODS: A total of 80 cases(80 eyes)APACG patients who underwent trabeculectomy in our hospital from June 2020 to January 2022 were collected in the case group. According to the postoperative efficacy, they were grouped into a success group of 60 cases(60 eyes)and a failure group of 20 cases(20 eyes). Another 86 cataract patients(86 eyes)who underwent phacoemulsification with normal intraocular pressure in our hospital during the same period were included in the control group. Enzyme linked immunosorbent assay was applied to detect the levels of CXCR2 and bFGF in aqueous humor. ROC curve was applied to analyze the value of predicting trabeculectomy failure in APACG patients by the levels of CXCR2 and bFGF in aqueous humor. Furthermore, multivariate Logistic regression was applied to analyze the influencing factors of trabeculectomy failure in APACG patients.RESULTS: The levels of CXCR2 and bFGF in the aqueous humor of the case group were significantly higher than those of the control group(P<0.05). The levels of CXCR2 and bFGF in the aqueous humor of the failed group and the proportion of patients with postoperative shallow anterior chamber were significantly higher than those of the successful group(P<0.05). The AUC for predicting trabeculectomy failure in APACG patients using CXCR2 and bFGF levels alone and in combination was 0.885, 0.883 and 0.953, respectively. CXCR2 and bFGF were independent risk factors for trabeculectomy failure in APACG patients(P<0.05).CONCLUSION: The levels of CXCR2 and bFGF in the aqueous humor of APACG patients are obviously elevated, and both are risk factors for trabeculectomy failure.
