Objective :
To explore the utility of a nomogram integrating contrast-enhanced CT radiomics with clinical features in the preoperative prediction of WHO/ISUP grade for clear cell renal cell carcinoma(ccRCC).
Methods:
A total of 214 patients with pathologically proven ccRCC who underwent enhanced CT scan before surgery were retrospectively included. According to the WHO/ISUP grade system, the cases were classified into low-grade(grades Ⅰ-Ⅱ) and high-grade(grades Ⅲ-Ⅳ), and then randomly divided into training and test set with a ratio of 4 ∶1. Regions of interest were segmented from both unenhanced and three-phase enhanced images, and radiomic features were extracted. Feature selection and dimensionality reduction were performed using Spearman rank correlation coefficients and LASSO regression, followed by the construction of the radiomic model with the KNN algorithm. Clinical and semantic imaging features were selected through univariate and multivariate analyses, and a clinical model was developed using the KNN algorithm. The clinical and radiomics signatures were used to construct a combined model and a nomogram was developed. The ROC curve and delong test were used to evaluate the diagnostic performance of the model, while calibration and decision curve analyses assessed its accuracy and clinical applicability.
Results:
8 clinical features and 11 radiomic features were selected. The combined model, integrating these clinical and radiomics signatures, exhibited robust predictive performance with AUC values of 0.887 in the training set and 0.800 in the test set. The calibration curve demonstrated good consistency between the nomogram model and actual outcomes, while decision curve analysis indicated a favorable net benefit for the nomogram.
Conclusion
The nomogram constructed by combining radiomics and clinical signatures can provide evidence for preoperative prediction of ccRCC grade and guide clinical decision-making.

Objective:To explore the direct effect of perceived social support on self-advocacy and the mediating effect of active coping strategies in breast cancer patients.Methods:A convenience sampling method was used to select 240 breast cancer patients hospitalized at Qilu Hospital of Shandong University from April 2023 to April 2024. General information questionnaire, the Female Self-Advocacy Scale in Cancer Survivorship (FSACS), the Simplified Ways of Coping Questionnaire (SWCQ), and the Perceived Social Support Scale (PSSS) were used to collect the data.Results:The effective response rate for the questionnaires was 93.75% (225/240). The total score for FSACS in 225 breast cancer patients was (75.36±9.88), the active coping score for SWCQ was (21.68±6.07), and the total score for PSSS was (55.63±8.04). The mediating effect analysis revealed that perceived social support had a direct positive predictive effect on self-advocacy ( β=0.420, P<0.01). Active coping played a mediating role in the relationship between perceived social support and self-advocacy, with a mediating effect value of 0.210, a 95% confidence interval of 0.112 to 0.318, and the mediating effect accounting for 33.33% of the total effect. Conclusions:Perceived social support not only positively affects the self-advocacy level of breast cancer patients but also indirectly influences it through the mediating role of active coping. Medical staff should emphasize improving perceived social support levels and encourage patients to adopt active coping strategies to enhance their self-advocacy.

ObjectiveTo investigate the mechanism by which 2,3,5,4'-tetrahydroxyldiphenylethylene-2-O-glucoside (THSG) mitigates cerebral ischemia/reperfusion (CI/R) injury by regulating mitochondrial calcium overload and promoting mitophagy. MethodsSixty male SD rats were randomized into sham, model, SAS (40 mg·kg-1), and low-, medium- and high-dose (10, 20, 40 mg·kg-1, respectively) THSG groups, with 10 rats in each group. The middle cerebral artery occlusion/reperfusion (MCAO/R) model was established by the modified Longa suture method. An oxygen-glucose deprivation/reoxygenation (OGD/R) model was constructed in PC12 cells. Neurological deficits were assessed via Zea Longa scoring, and cerebral infarct volume was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Structural and functional changes of cortical neurons in MCAO/R rats were assessed by hematoxylin-eosin and Nissl staining. PC12 cell viability was detected by cell counting kit-8 (CCK-8) assay, and mitochondrial calcium levels were quantified by Rhod-2 AM. Immunofluorescence was used to detect co-localization of PTEN-induced kinase 1 (PINK1) and leucine zipper/EF-hand-containing transmembrane protein 1 (LETM1) in neurons. Transmission electron microscopy (TEM) was employed to observe mitochondrial morphology in neurons. Western blot was employed to analyze the expression of translocase of outer mitochondrial membrane 20 (TOMM20), autophagy-associated protein p62, microtubule-associated protein light chain 3 (LC3), cysteinyl aspartate-specific proteinase-9 (Caspase-9), B-cell lymphoma 2-associated protein X (Bax), and cytochrome C (Cyt C). ResultsCompared with the sham group, the model group exhibited increased infarct volume (P<0.01) and neurological deficit scores (P<0.01), neuronal structure was disrupted with reduced Nissl bodies. (P<0.01), mitochondrial swelling/fragmentation, decreased PINK1/LETM1 co-localization (P<0.01), upregulated protein levels of LC3Ⅱ/LC3Ⅰ, TOMM20, Caspase-9, Bax, and Cyt C (P<0.01), downregulated protein level of p62 (P<0.05), weakened PC12 viability (P<0.01), and elevated mitochondrial calcium level (P<0.01). Compared with the model group, THSG and SAS groups showed reduced infarct volumes (P<0.05,P<0.01) and neurological deficit scores (P<0.05,P<0.01), mitigated mitochondrial damage, and increased PINK1/LETM1 co-localization (P<0.01). Medium/high-dose THSG and SAS alleviated the neurological damage, increased Nissl bodies (P<0.05,P<0.01), downregulated the protein levels of p62, TOMM20, Caspase-9, Bax, and Cyt C (P<0.05,P<0.01), and elevated the LC3Ⅱ/LC3Ⅰ level (P<0.05,P<0.01). High-dose THSG enhanced PC12 cell viability (P<0.01), increased PINK1/LETM1 co-localization (P<0.01), and reduced mitochondrial calcium (P<0.01). ConclusionTHSG may exert the neuroprotective effect on CI/R injury by activating the PINK1-LETM1 signaling pathway, reducing the mitochondrial calcium overload, and promoting mitophagy.

Objective:To investigate the numbers of peripheral blood CD4 +T cell subpopulations in patients with elderly-onset rheumatoid arthritis (EORA) and its clinical significance. Methods:A total of 188 patients with newly diagnosed RA in the department of rheumatology and immunology of the Second Hospital of Shanxi Medical University from January 2020 to December 2023 were collected, including 48 cases of EORA (age of onset: ≥60 years old), 140 cases of young-onset rheumatoid arthritis (YORA) (18 years old ≤ age of onset < 60 years old). Meanwhile, 151 healthy controls (HC) were collected, of which 31 persons aged 60-85 years were included as HC group 1 (HC 1) and 120 individuals aged 18-59 years were included as HC group 2 (HC 2). Peripheral blood CD4 +T lymphocyte subsets of these participants were assessed by flow cytometry. Differences between groups were analyzed using independent-samples t test, Mann-Whitney U test or χ2 test. Results:Compared with healthy individuals, the absolute counts and percentages of peripheral blood Treg cells in patients with EORA were significantly decreased [absolute counts: 32.65 (23.04, 47.73) cells/μl vs. 23.03 (15.28, 32.12) cells/μl, Z=-3.35, P=0.001; percentages: 5.12%(4.13%, 6.16%) vs. 3.72% (2.79%, 4.82%), Z=-4.10, P<0.001], while the Th17/Treg cell ratio was increased [0.16 (0.12, 0.29) vs. 0.26 (0.18, 0.46), Z=-2.94, P=0.003], the differences are all significant. There was a tendency with higher absolute counts and percentages of Treg [absolute counts: 23.03 (15.28, 32.12) cells/μl vs. 20.97 (14.01, 30.64) cells/μl, Z=-0.58, P=0.561; percentages: 3.72%(2.79%, 4.82%) vs. 3.38% (2.39%, 4.71%), Z=-1.06, P=0.287] and lower Th17/Treg ratios [0.26 (0.18, 0.46) vs. 0.27 (0.19, 0.46), Z=-0.32, P=0.751] in EORA when compared to patients with YORA, but no significant differences were observed. Conclusion:Patients with EORA also have the reduced numbers of peripheral blood Treg cells and immune imbalance of Th17/Treg, suggesting that immune imbalance or dysfunction caused by defects in Treg cell counts and/or function contributes to the development of EORA, and that targeting Treg cells may be a promising therapeutic strategy for EORA.

Objective:To investigate the relationship between thoracic aortic calcification (TAC) and autonomic nervous system (ANS) function in patients receiving continuous ambulatory peritoneal dialysis (CAPD).Methods:It was a cross-sectional study. The CAPD patients with dialysis duration >6 months between January and December 2022 were retrospectively enrolled. The baseline clinical data, heart rate variability (HRV) data such as standard deviation of all normal to normal intervals (SDNN), root mean square of successive differences between adjacent normal-to-normal intervals (RMSSD), high frequency (HF), very low frequency (VLF), low frequency (LF), LF/HF, acceleration capacity (AC) and deceleration capacity (DC), and skin sympathetic nerve activity (SKNA) were collected. TAC was defined as TAC score (TACS) >100 AU. The patients were divided into TACS >100 AU group and TACS≤100 AU group based on whether the thoracic aorta was calcified. The differences of those data between the two groups were compared. Logistic regression model was used to analyze the related factors of TAC. Spearman correlation analysis method was used to analyze the correlation between peripheral blood neuropeptide Y, ANS parameters, average amplitude SKNA (aSKNA) and TACS. Cox regression model was used to analyze the risk factors of all-cause mortality in patients with CAPD.Results:The study included 106 CAPD patients with 50 males (47.2%), age of (46.04±11.10) years and dialysis duration of (41.55±30.52) months. TACS>100 AU group exhibited significantly lower heart rate ( t=2.015, P=0.046), DC ( t=2.131, P=0.035), LF/HF ( Z=3.332, P<0.001) and ln(LF/HF) ( t=3.326, P=0.001), and higher AC ( t=-2.392, P=0.019) than TACS≤100 AU group. Multivariate logistic regression analysis results showed that after adjusting for age and eosinophil count, lnVLF ( OR=0.66, 95% CI 0.45-0.98, P=0.038), lnLF ( OR=0.69, 95% CI 0.49-0.97, P=0.032), DC ( OR=0.79, 95% CI 0.64-0.99, P=0.039) and AC ( OR=1.32, 95% CI 1.04-1.68, P=0.021) were independently correlated with the risk of TAC. Spearman correlation analysis showed that neuropeptide Y level in peripheral blood was correlated with aSKNA ( r=0.23, P=0.017), lnSDNN ( r=-0.20, P=0.036) and TACS ( r=0.19, P=0.048). During the follow-up period of (25.8±4.2) months, 5 patients (4.72%) died, including 1 patient in the TACS≤100 AU group and 4 patients in the TACS>100 AU group. Compared with the survival group, the death group had higher TACS ( Z=-2.262, P=0.024) and lower LF/HF ( Z=-2.750, P=0.006). Cox regression analysis results showed that increased ln(LF/HF) was an independent influencing factor for all-cause mortality in CAPD patients ( HR=0.22, 95% CI 0.05-0.83, P=0.026). Conclusions:HRV parameters (lnVLF, lnLF, AC and DC) of CAPD patients are independently associated with TAC. The dysfunction of ANS in CAPD patients (especially the decreased vagus nerve activity) may promote TAC.

OBJECTIVE:
To explore the feasibility and effectiveness of suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique for avulsion fractures of the inferior pole of the patella.
METHODS:
A clinical data of 38 patients with avulsion fractures of the inferior pole of the patella, who met the selective criteria and were admitted between September 2021 and April 2023, was retrospectively analyzed. The fractures were treated with suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique in 18 cases (group A) and steel wire tension-band fixation in 20 cases (group B). There was no significant difference in terms of age, gender, cause of fracture, side of fracture, and disease duration between the two groups ( P>0.05). The length of incision, operation time, occurrence of complications, the range of motion of knee joint, and Böstman score of knee joint at last follow-up were recorded. The fracture healing was evaluated through X-ray films and the time of fracture healing was recorded.
RESULTS:
All incisions healed by first intention. The length of incision was significantly shorter in group A than in group B ( P<0.05). There was no significant difference in the operation time between the two groups ( P>0.05). All patients were followed up 12-24 months (mean, 16.1 months). X-ray films showed that all fractures healed and there was no significant difference in the healing time between the two groups ( P>0.05). At last follow-up, the range of motion and Böstman score of the knee joint in group A were significantly better than those in group B ( P<0.05). During follow-up, 1 patient (5.6%) in group A had one anchor mild prolapse and 3 patients (15.0%) occured internal fixation irritation in group B. But there was no significant difference in the incidence of complications between the two groups ( P>0.05).
CONCLUSION
For the avulsion fractures of the inferior pole of the patella, the suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique has advantages of reliable fixation, small incision, avoidance of secondary operation to remove internal fixator, and fewer complications, with definite effectiveness.
