ObjectiveTo analyze the risk factors for long-term cardiovascular events in patients undergoing long-term peritoneal dialysis (PD), and to construct and validate a visual nomogram prediction model based on multiple parameters. MethodsA prospective cohort study was conducted, consecutively enrolling 248 maintenance PD patients (dialysis duration ≥ 3 months). Demographic characteristics, clinical indicators, laboratory parameters, and echocardiographic indices (including left ventricular ejection fraction [LVEF], ratio of early diastolic mitral inflow velocity to early diastolic mitral annular velocity (E/e’), etc.) were collected. The composite endpoint was defined as the occurrence of cardiovascular events or cardiovascular death, with non-cardiovascular death as the competing risk and loss to follow-up or the end of follow-up as censoring events. Fine-Gray competing risks model was used to screen independent predictors, based on which a nomogram model was constructed. Internal validation was performed using the Bootstrap method (1 000 resamplings), and the concordance index (C-index) and time-dependent receiver operating characteristic (time-dependent ROC) curve were calculated to evaluate the model performance. ResultsWith a median follow-up of 29 months (interquartile range: 24–35 months), 88 patients (35.48%) reached the composite endpoint, including 80 cases of cardiovascular events and 8 cases of cardiovascular death, and 4 patients died of non-cardiovascular causes. Multivariate Fine-Gray analysis revealed that age, diabetes mellitus, hemoglobin (HGB) level and E/e' ratio were independent influencing factors of the composite endpoint. Specifically, each 1-year increase in age was associated with a 3.0% increase in the risk of the composite endpoint (HR=1.030, P=0.006); patients with diabetes mellitus had a 167.9% higher risk compared with non-diabetic patients (HR=2.679, P=0.007); each 1g/L increase in HGB level contributed to a 1.5% reduction in the risk (HR=0.985, P=0.003); and each 0.1 increase in E/e' ratio led to a 7.2% increase in the risk (HR=1.072, P=0.045). The nomogram model had a C-index of 0.76 (95% CI: 0.698–0.820), and the AUC of the time-dependent ROC curve reached 0.849 at 23 months of follow-up. ConclusionIncreased age, complicated with diabetes mellitus, decreased HGB, and elevated E/e' ratio are independent risk factors of long-term occurrence of cardiovascular events and cardiovascular death in patients undergoing long-term PD. The nomogram model constructed based on the above variables has good predictive value and clinical applicability, which can provide a reference for cardiovascular risk stratification and individualized intervention in long-term PD patients.

Objective :
To verify the feasibility of using a homemade lung phantom for quality control of Cyberknife by
comparing the measurement results of the homemade lung phantom and CIRS dynamic phantom in E2E testing of Cyberknife lung tracking.
Methods :
The patient treatment process was simulated, including CT positioning, plan design, irra-
diation implementation, film scanning, and analysis using the homemade phantom and CIRS phantom. The two phantoms
were measured five times using MLC under the S7 generation Cyberknife and five times using Iris under the M6 generation
Cyberknife. The differences in measurement results between the two phantoms were analyzed using independent sample t-test.
Results :
For the S7 generation Cyberknife, the statistical analysis of differences between the two phantoms in the detection values on the X-axis, Y-axis, Z-axis, and total deviation showed P values of 0.236, 0.175, 0.289, and 0.668, respect-
ively. For the M6 generation Cyberknife, the statistical analysis showed P values of 0.880, 0.891, 0.573, and 0.433, respect-
ively. The P values were all > 0.05. Therefore, there were no statistically significant differences in the detection results
between the homemade lung phantom and the CIRS phantom under the S7 and M6 generation Cyberknife. The total deviation values were <1.5 mm.
Conclusion
The homemade lung phantom and CIRS phantom have consistent measurement
results in the E2E testing of Cyberknife lung tracking and meet the requirements of Report of AAPM TG-135 and WS 667-
2019 standard. Therefore, the homemade lung phantom is feasible for clinical quality control of Cyberknife.

Objective To explore the correlation between serum fibroblast growth factor-23 (FGF23) concentration and heart failure and all-cause death in patients with end-stage renal disease (ESRD).Methods The prospective cohort study design was used in the present study.The ESRD patients who were admitted to the department of ne-phropathy in the Hospital and without heart failure symptoms were recruited in this study.The data of patients was collected through baseline questionnaires, physical examinations, echocardiography, and laboratory examinations.The serum FGF23 levels were measured by enzyme-linked immunosorbent assay (ELISA) .The follow-up time was 2 years.The onset of heart failure (ACC/AHA stage C-D) and all-cause death were composite endpoint events.The Cox proportional risk model was used to explore the risk factors of outcome events.Through subgroup analyses and interaction analyses, further exploration was conducted to determine whether there was heterogeneity in the as-sociation between FGF23 and outcome events in different subgroups.Results Ultimately,107 ESRD patients were included in this study, with an average age of (52.00 ± 12.51) years.There were 39 males (36.45%), and the median follow-up time was 23 months (21, 25 months).There were 32 (29.9%) outcome events, of which 22 (20.6%) onset of heart failure and 10 (9.3%) all-cause of deaths.The results of this study showed that the con-centration of FGF23 in the outcome event group was significantly higher than that in the non-event group [ (4.40 ± 1.16) pmol/ml vs (3.85 ± 0.82) pmol/ml,P<0.05].The Cox proportional risk model showed that the elevated FGF23 was associated with increased risk of the composite endpoint events in ESRD patients (HR=1.730 , 95%CI:1.164-2.570 , P=0.007) .Subgroup analyses showed that there was an interactive effect between FGF23 levels and gender on the risk of cardiovascular outcome events.Especially in male ESRD patients, the increased FGF23 level was correlated with a higher risk of cardiovascular events (P-interaction <0.05).Conclusion Elevated serum FGF23 is an independent risk factor for the onset of heart failure and all-cause of mortality in ESRD patients, especially in male patients.

Objective To establish an allogeneic rat model of endometriosis and to evaluate the effects of gonadotropin-releasing hormone (GnRH) agonist GenSci006 on experimental rat endometriosis. Methods Endometrium from SPF grade donor female SD rats were transplanted onto the abdominal wall of recipient female rats to construct an allogeneic endometriosis model. The rats undergoing sham surgery were divided into the sham group. Three weeks later, the length, width and height of the ectopic endometrium were measured, and the volume of the endometrium (V1) was calculated before drug administration. The modeling rats were randomly divided into four groups: model group, triptorelin group (0.25 mg/kg), GenSci006-1 group (0.125 mg/kg) and GenSci006-2 group (0.25 mg/kg). Each group had 16 rats and received a single dose of the corresponding drug. The sham group and model group were administered an equal volume of solvent. Three weeks after administration, ectopic endometrium was measured to calculate the volume V2 and inhibition rate. The effect of GenSci006 on rat uterus and ovarian tissues was assessed by comparing organ coefficients and changes in pathological sections. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of serum estradiol (E2), progesterone (P4), follicle stimulating hormone (FSH), and luteinizing hormone (LH). Real-time fluorescent quantitative PCR was used to detect the expression of GnRH receptor (GnRHR) mRNA in the hypothalamus and pituitary. Western blot was used to detect the expression of estradiol receptor alpha (ERα), beta (ERβ) and progesterone receptor (PR) in ectopic endometrium. Results Three weeks after administration, compared with the model group, the body weight of rats in the triptorelin and GenSci006-2 groups significantly increased (P < 0.05), while the volume of ectopic endometrium significantly decreased (P < 0.05). Compared with the sham group, the model group showed no significant changes in uterine and ovarian organ coefficients or endometrial thickness (P > 0.05). Compared with the model group, the uterine organ coefficients and endometrial thickness were significantly reduced in the triptorelin and GenSci006-2 groups (P < 0.05). Compared with the sham group, the serum levels of E2, P4, FSH and LH in the model group showed no significant changes (P > 0.05). Compared with the model group, the ovarian organ coefficient and serum P4 levels of rats in the Triptorelin, GenSci006-1, and GenSci006-2 groups were significantly reduced (P < 0.05), while the serum LH levels of rats in the GenSci006-1 group were significantly increased (P < 0.05). However, there were no significant changes in serum E2 and FSH levels in each group (P > 0.05). Compared with the model group, the expression levels of GnRHR mRNA in the pituitary tissue of rats in the triptorelin and GenSci006-2 groups were significantly downregulated (P < 0.05), with no significantly changes in the hypothalamus (P > 0.05). There were no significant changes in the expression level of GnRHR mRNA in the hypothalamus or the protein levels of ERα, ERβ and PR in the ectopic endometrial tissue in any group (P > 0.05). Conclusion The allogeneic endometriosis rat model is a suitable animal model for screening and evaluating drugs for treating endometriosis. The volume of ectopic endometrium, inhibition rate, uterine and ovarian organ coefficients, and serum E2 levels may serve as indicators for detecting drug efficacy.
