Objective: To analyze the effects of blue light on the formation of kidney stones. Methods: A total of 40 rats were randomly divided into 4 groups：A，B，C，and D，with 10 rats in each group.Rats in groups C and D were administered with a mixture of 10 g/L ethylene glycol，20 g/L ammonium chloride，and 100 g/L calcium gluconate via gavage (2 mL per mouse)，while rats in groups A and B received an equal volume of physiological saline via gavage.From the second day after gavage，rats in groups A and C were subjected to twice-daily blue light irradiation (one hour per session) as an intervention，while rats in groups B and D were subjected to fluorescent lamp irradiation using the same method.After 4 weeks of intervention，the 24-hour urine samples were collected，and the rats were then euthanized for the collection of blood and kidney tissue samples.Serum levels of antidiuretic hormone (ADH)，urinary Ca ，and urinary oxalate (Oxa) were measured.Levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in kidney tissues were detected using ELISA.Von Kossa staining was performed to observe pathological changes in kidney tissues and the presence of calcium salt crystals in the kidneys. Results: Compared with groups A and B，groups C and D showed higher accumulation of calcium salt crystals in renal tissues，as well as elevated levels of ADH，urinary Ca ，urinary Oxa，and MDA in renal tissues, additionally，the SOD level in renal tissues was lower (P<0.05).Compared with group D，group C exhibited higher accumulation of calcium salt crystals in renal tissues，along with increased levels of ADH，urinary Ca ，urinary Oxa，and MDA in renal tissues；conversely，the SOD level in renal tissues was lower (P<0.05). Conclusion: Blue light may increase the formation of kidney stones in rats by promoting the secretion of ADH in serum and oxidative stress in kidney tissues through the brain-kidney axis.

Objective:To explore the application value of real-time vascular quantification stiffness (R-VQS) technique in evaluating carotid artery elasticity and hemodynamic status in type 2 diabetic nephropathy (T2DN).Methods:The clinical data of 86 patients with T2DN treatment in the Fifth People′s Hospital of Zhuhai from March 2020 to March 2022 were collected retrospectively, according to the clinical stage, 44 patients were in the early stage group and 42 patients were in the clinical stage group. All of them underwent R-VQS technique to obtain carotid artery elasticity parameters stiffness index (HC), systolic diameter (Diam), diameter change value (Dist) and hemodynamic indexes pulse conduction velocity (PWV). Among the 86 patients, 21 had atherosclerosis (AS) and 65 did not. The differences of HC, Diam, Dist and PWV between the patients with and without AS were compared, and the value of HC, Diam, Dist and PWV in diagnosing T2DN complicated with AS was analyzed by receiver operating characteristic (ROC) curve.Results:The HC, Diam and PWV in the clinical phase group were higher than those in the early phase group, and Dist was lower than that in the early phase group: 4.76 ± 0.60 vs. 4.15 ± 0.52, (8.69 ± 1.13) mm vs. (7.21 ± 0.84) mm, (7.42 ± 0.63) m/s vs. (6.84 ± 0.57) m/s, (0.27 ± 0.07) mm vs. (0.35 ± 0.09) mm, there were statistical differences ( P<0.05). The HC, Diam and PWV in the patients with AS were higher than those in the patients without AS, and Dist was lower than that in the patients without AS: 4.82 ± 0.63 vs. 4.33 ± 0.51, (8.85 ± 1.18) mm vs. (7.63 ± 1.06) mm, (7.68 ± 0.75) m/s vs. (6.94 ± 0.59) m/s, (0.24 ± 0.05) mm vs. (0.33 ± 0.10) mm, there were statistical differences ( P<0.05). ROC curve analysis results showed that the area under the curve (AUC) of the combined diagnosis of T2DN complicated with AS by HC, Diam, Dist and PWV was 0.921, and the diagnostic sensitivity and specificity were 90.48% and 84.62%, respectively. Conclusions:R-VQS technology can detect abnormal changes in carotid elasticity and hemodynamics in patients with T2DN, and can diagnose T2DN complicated with AS. It can provide a reference basis for clinical prevention and treatment of cardiovascular and cerebrovascular complications in T2DN patients.

A young female patient with acne and elevated testosterone level underwent plasma steroid hormones testing and found a significant increase in aldosterone. We excluded testing interference and verified the absence of hypertension, hypokalemia, and adrenal occupancy, as well as primary and secondary hyperaldosteronism. During follow-up, a temporal correlation was found between aldosterone levels and the use of drospirenone and ethinylestradiol tablets. It was observed that the combination of drospirenone and ethinylestradiol could lead to the increase of aldosterone level and the concentration ratio of aldosterone to direct renin through different mechanisms. Drospirenone exerts an antagonistic effect on mineralocorticoid receptor to prevent the development of hypertension or hypokalemia. In clinical practice, it is necessary to pay attention to the effect of this drug on screening markers for primary aldosteronism. In the laboratory examination, when female patients with no symptoms of hypertension and hypokalemia but with elevated aldosterone levels are encountered, it can be verified whether they have a history of use of compound estrogen-progestin such as drospirenone and ethinylestradiol tablets, and appropriate tips are provided in the report.

Objective:To investigate the safety and efficacy of FOLFOX (5-fluorouracil + calcium folinate + oxaliplatin) hepatic arterial infusion chemotherapy (FOLFOX-HAIC) combined with immune and targeted therapy as triple combination therapy for patients with single China Liver Cancer Staging (CNLC) Ⅰb hepatocellular carcinoma.Methods:A total of 20 patients with single CNLC Ⅰb hepatocellular carcinoma who received FOLFOX-HAIC combined with immune and targeted therapy as triple combination therapy in the First Affiliated Hospital of Guangxi Medical University from October 2021 to August 2022 were included. The clinical data of all patients was retrospectively analyzed. There were 18 males and 2 females, with the age of (55.1±9.9) years. Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and Modified Response Evaluation Criteria in Solid Tumors (mRECIST) were used to evaluate the efficacy of FOLFOX-HAIC combined with immune and targeted therapy, and the clinical safety of triple combination therapy was evaluated by common terminology criteria for adverse events 4.0.Results:According to RECIST 1.1, objective response rate of 20 patients was 70.0% (14/20) and disease control rate was 100.0% (20/20) after 2 cycles of treatment (one cycle of FOLFOX-HAIC plus programmed death-1 antibody). According to mRECIST, objective response rate was 90.0% (18/20) and the disease control rate was 100.0% (20/20) after 2 cycles of treatment. Following the treatment, 12 patients (60.0%) received liver tumor resection, and all of them achieved R 0 resection, 2 patients (10.0%) received radiotherapy, 3 patients (15.0%) stopped drug treatment for surgery, 2 patients (10.0%) refused surgery, and 1 patient (5.0%) died of multiple organ failure caused by immune hepatitis. According to pathological results, 3 patients (25.0%, 3/12) achieved pathological complete response, and 4 patients (33.3%, 4/12) achieved major pathological response. In the safety evaluation, the overall incidence of adverse events was 100.0% (20/20). Seven patients (35.0%) had grade 3 adverse events and 1 patient (5.0%) died of multiple organ failure due to immune hepatitis (grade 5). Grade 1-3 adverse events could be relieved after symptomatic treatment. Conclusion:The triple combination therapy of FOLFOX-HAIC combined with immune and targeted therapy is safe and has high objective response rate and disease control rate, which could be a new strategy for the neoadjuvant treatment of hepatocellular carcinoma.

Objective:To evaluate the diagnostic performance of the prostate imaging reporting and data system version 2.1 (PI-RADS v2.1) based on multiparametric MRI (mpMRI) in the detection of clinically significant prostate cancer (csPCa).Methods:A total of 561 patients who underwent prostate mpMRI in the First Affiliated Hospital of Guangxi Medical University from June 2015 to December 2020 due to elevated prostate specific antigen were collected ambispectively. The patients were divided into csPCa group (276 cases) and non-csPCa group (285 cases) according to pathological findings. Prostate were scored according to the PI-RADS v2.1 scoring standard by a junior and a senior radiologist. The prostate volume was measured and the prostate specific antigen density (PSAD) was calculated. The diffusion-weighted imaging and dynamic contrast-enhanced MRI images were processed to measure the quantitative parameters of the index lesion, including apparent diffusion coefficient (ADC), volume transfer constant (K trans) and rate constant (K ep) values. The Mann-Whitney U test was used to compare the difference in parameters between the two groups. The predictors of csPCa were screened by logistic regression analysis. Predictive model of multi-parameter was established. The receiver operator characteristic curves were used to evaluate the efficacy of PI-RADS v2.1 and the model in diagnosing csPCa, and the comparisons of area under the curve (AUC) were conducted by DeLong test. Results:Compared with non-csPCa group, the patients in csPCa group had higher PI-RADS score of senior physician, PSAD, K trans and K ep value, lower ADC value ( Z=-16.69, -12.49, -3.43, -4.67, 13.91, all P<0.001). The PI-RADS scores of senior physician (OR=3.064, 95%CI 2.428-3.866, P<0.001), PSAD (OR=1.554, 95%CI 1.170-2.064, P=0.002) and ADC value (OR=0.095, 95%CI 0.032-0.288, P<0.001) were the predictors of csPCa. The AUC of junior, senior physician PI-RADS and combined prediction model were 0.861 (95%CI 0.830-0.892), 0.895 (95%CI 0.868-0.922) and 0.923 (95%CI 0.898-0.944). The pairwise difference was statistically significant (the PI-RADS score between the junior and senior physicians Z=3.24, P=0.001, the difference between the PI-RADS score of junior physician and prediction model Z=5.54, P<0.001, the difference between the PI-RADS score of senior physician and prediction model Z=4.20, P<0.001). Conclusion:Based on mpMRI, the application of PI-RADS v2.1 by junior and senior radiologists has the high diagnostic efficacy for csPCa, and the multi-parameter model has the best diagnostic efficacy for csPCa.

The heterogeneity of exhausted T cells (Tex) is a critical determinant of immune checkpoint blockade therapy efficacy. However, few studies have explored exhausted T cell subpopulations in human cancers. In the present study, we examined samples from two cohorts of 175 patients with head and neck squamous cell cancer (HNSCC) by multiplex immunohistochemistry (mIHC) to investigate two subsets of Tex, CD8⁺PD1⁺TCF1⁺ progenitor exhausted T cells (TCF1⁺Tex^prog) and CD8⁺PD1⁺TCF1^- terminally exhausted T cells (TCF1^-Tex^term). Moreover, fresh tumor samples from 34 patients with HNSCC were examined by flow cytometry and immunohistochemistry to further investigate their properties and cytotoxic capabilities and their correlation with regulatory T cells (Tregs) in the tumor immune microenvironment (TIME). mIHC and flow cytometry analysis showed that TCF1^-Tex^term represented a greater proportion of CD8⁺PD1⁺Tex than TCF1⁺Tex^prog in most patients. TCF1⁺Tex^prog produced abundant TNFα, while TCF1^-Tex^term expressed higher levels of CD103, TIM-3, CTLA-4, and TIGIT. TCF1^-Tex^term exhibited a polyfunctional TNFα⁺GZMB⁺IFNγ⁺ phenotype; and were associated with better overall survival and recurrence-free survival. The results also indicated that larger proportions of TCF1^-Tex^term were accompanied by an increase in the proportion of Tregs. Therefore, it was concluded that TCF1^-Tex^term was the major CD8⁺PD1⁺Tex subset in the HNSCC TIME and that these cells favor patient survival. A high proportion of TCF1^-Tex^term was associated with greater Treg abundance.
