[Objective] To analyze the clinicopathological characteristics of treatment-naive patients with highly suspected prostate cancer (PCa) with prostate-specific antigen (PSA) level ≥20 ng/mL, to provide reference for promoting early screening of PCa. [Methods] A retrospective analysis was conducted on the clinical data of treatment-naive patients with PSA level ≥20 ng/mL, undergoing prostate biopsy for highly suspected PCa at the Department of Urology, Tianjin Medical University Second Hospital during Jan.2013 and Jun.2023. The correlation between patients' age, body mass index (BMI), PSA, prostate volume (PV), prostate cancer-specific antigen density (PSAD), prostate imaging reporting and data system (PI-RADS) score, and International Society of Urological Pathology (ISUP) grade with highly suspected PCa metastasis and PSA stratification were analyzed. [Results] A total of 1778 suspected patients were enrolled. Pathological findings confirmed PCa in 1465 cases (82.4%), with 487(33.2%) diagnosed as metastatic PCa. Over the past decade, the number of patients undergoing prostate biopsy for highly suspected PCa and being confirmed has been increasing annually, with the proportion of metastatic cases remaining at around 30%. Compared with those with PSA level being 20-50 ng/mL, patients with PSA level >50 ng/mL had older age, lower BMI, higher PSAD, higher PI-RADS, higher ISUP, more diverse pathological types, and a higher incidence of metastasis (P<0.05) with lower proportion of urban residents. Additionally, analysis of metastatic PCa cases showed that 46.8%(228/487) had oligometastasis (≤5 metastatic lesions), including 99.0% bone metastasis, 4.1% extraregional lymph node metastasis, and 4.3% other organ metastasis. [Conclusion] Over the past 10 years, there has been a continuous increase in the number of treatment-naive biopsied cases and newly diagnosed cases of highly suspicious PCa with PSA level ≥20 ng/mL, while the proportion of metastatic cases remains high. Therefore, proactive efforts should be made to promote early screening of high-risk suspected cases.

Background Exposure to polycyclic aromatic hydrocarbons (PAHs) is associated with the development of metabolic syndrome (MS). However, the role of amino acids in PAH-induced MS remains unclear. Objective To explore the impact of PAHs exposure on the incidence of MS among coking workers, and to determine potential modifying effect of amino acid on this relationship. Methods Unmatched nested case-control design was adopted and the baseline surveys of coking workers were conducted in two plants in Taiyuan in 2017 and 2019, followed by a 4-year follow-up. The cohort comprised 667 coking workers. A total of 362 participants were included in the study, with 84 newly diagnosed cases of MS identified as the case group and 278 as the control group. Urinary levels of 11 PAH metabolites and plasma levels of 17 amino acids were measured by ultrasensitive performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Logistic regression was used to estimate the association between individual PAH metabolites and MS. Stratified by the median concentration of amino acids, Bayesian kernel machine regression (BKMR) model was employed to assess the mixed effects of PAHs on MS. Due to the skewed data distribution, all PAH metabolites and amino acids in the analysis were converted by natural logarithm ln (expressed as lnv). Results The median age of the 362 participants was 37 years, and 83.2% were male. Compared to the control group, the case group exhibited higher concentrations of urinary 2-hydroxyphenanthrene (2-OHPhe), 9-hydroxyphenanthrene (9-OHPhe), and hydroxyphenanthrene (OHPhe) (P=0.005, P=0.049, and P=0.004, respectively), as well as elevated levels of plasma branched chain amino acid (BCAA) and aromatic amino acid (AAA) (P<0.05). After being adjusted for confounding factors, for every unit increase in lnv_2-OHPhe in urine, the OR (95%CI) of MS was 1.57 (1.11, 2.26), and for every unit increase in lnv_OHPhe, the OR (95%CI) of MS was 1.82 (1.16, 2.90). Tyrosine, leucine, and AAA all presented a significant nonlinear correlation with MS. At low levels, tyrosine, leucine, and AAA did not significantly increase the risk of MS, but at high levels, they increased the risk of MS. In the low amino acid concentration group, as well as in the low BCAA and low AAA concentration groups, it was found that compared to the PAH metabolite levels at the 50th percentile (P₅₀), the log-odds of MS when the PAH metabolite levels was at the 75th percentile (P₇₅) were 0.158 (95%CI: 0.150, 0.166), 0.218 (95%CI: 0.209, 0.227), and 0.262 (95% CI: 0.241, 0.282), respectively, However, no correlation between PAHs and MS was found in the high amino acid concentration group. Conclusion Amino acids modify the effect of PAHs exposure on the incidence of MS. In individuals with low plasma amino acid levels, the risk of developing MS increases with higher concentrations of mixed PAH exposure. This effect is partly due to the low concentrations of BCAA and AAA.

ObjectiveTo observe the effect of enriched environment (EE) combined with acupuncture at head point (HA) on behavior in rats with autism spectrum disorder. MethodsHealthy female Wistar rats were given peritoneal injection of sodium valproate at 12.5 days of gestation. Twenty-four male offspring rats were randomly selected and then randomly divided into model group (n = 6), EE group (n = 6), HA group (n = 6) and EE combined with HA group (the combined group, n = 6). Six male offspring rats born from female mice injected with the same amount of saline intraperitoneally were as control group. After four weeks of treatment, all the five groups were tested with three-chamber test and marble burying test, and the sociability index, the social novelty index and the number of buried marbles were recorded. The levels of interleukin (IL)-1β and IL-6 in peripheral blood were determined by enzyme-linked immunosorbent assay (ELISA). ResultsAfter treatment, compared with the model group, the sociability index and the social novelty index improved (P < 0.05), the number of buried marbles reduced (P < 0.05), and the levels of IL-6 and IL-1β in peripheral blood decreased in EE group, HA group and the combined group (P < 0.05); while the combined group was the best (P < 0.01). ConclusionBoth EE or acupuncture at HA could improve behavioral symptoms, and reduce the expression of inflammatory factors in rats with autism spectrum disorder. The combination of the two methods showed the best result.

Adverse reactions commonly associated with apalutamide include hot flashes, fatigue, joint pain, rash, hypertension, and anemia. Apalutamide-induced agranulocytosis is relatively rare. In this paper, we reported a case with metastatic hormone-sensitive prostate cancer who developed agranulocytosis after taking apalutamide for one month. The patient’s neutrophil count returned to normal with appropriate supportive therapy, and no significant decrease in neutrophil count was observed during 10 months of follow-up after discharge.

Objective To investigate the correlation between uric acid to high-density lipoprotein cholesterol ratio(UHR)and late recurrence after radiofrequency ablation in patients with non-valvular atrial fibrillation(AF).Methods The clinical data of 586 patients with non-valvular AF underwent catheter radiofrequency ablation for the first time from January 2018 to January 2022 were selected,and the study population was classified into a low-value group(n=196),a medium-value group(n=195),and a high-value group(n=195)according to the trichoto-mous method based on the UHR value,with late recurrence of AF as the endpoint event of the follow up.The gener-al data and laboratory indexes were compared among the three groups.Survival curves were estimated and plotted u-sing the Kaplan-Meier method.Multivariate COX regression analysis was used to evaluate the independent correla-tion between UHR and recurrence of AF after ablation,followed by subgroup analysis.Results Late recurrence of AF was documented in a total of 182(31.1％)patients during the follow-up time.The Kaplan-Meier survival curve showed a gradual decrease in the maintenance rate of sinus rhythm across the UHR low-value group,middle-value group,and high-value group(Log-rank test,P＜0.001).In the fully-adjusted model,compared with the patients in the low-value group,the medium-value and high-value groups had a post-ablation late recurrence of AF with HR(95％CI,P)were 1.56(0.99-2.42,P=0.057)and 2.03(1.28-3.23,P=0.003),respectively.Subgroup a-nalysis showed that the association between UHR and late recurrence of AF after ablation was remarkable among pa-tients with aged≥60 years,BMI≥25 kg/m2,persistent AF,LAD≥4.3 cm,hypertension,without heart failure and without hyperlipidemia.Conclusion Higher UHR values in patients with non-valvular AF are independently asso-ciated with an increased risk of late recurrence of AF after radiofrequency ablation procedures.

Autophagy is a highly conserved cellular degradation pathway that degrades lipid droplets through a process called"lipophagy".Lipophagy can selectively recognize lipid substances and degrade them,promoting β oxidation and thereby maintaining the balance of intracellular lipid metabolism.The liver regulates lipid droplet metabolism through lipophagy signaling pathways or key molecules,thereby alleviating hepatic steatosis and improving nonalcoholic fatty liver disease(NAFLD).This article reviews the latest advances in the degradation of hepatic lipid droplets through the three autophagic pathways of macroautophagy,molecular chaperone-mediated autophagy,and microautophagy.The major signaling pathways of AMPK/mTOR-ULK1,ATGL-SIRT1,FGF21-JMJD3,and Akt are involved in the regulation of the lipophagy process and help to maintain the homeostasis of lipid metabolism in the liver,so as to provide new ideas for clinical prevention and treatment of NAFLD.

Objective To explore the effect of galangin(Gal)on inflammation in hepatitis B rats.Methods The rats were randomly divided into control group,hepatitis B group,Gal-L and Gal-H groups,positive drug lamivudine group and Gal-H+AMPK inhibitor(compound C)group with 12 in each.After modeling,medication treatment was performed once a day for 8 weeks.The level of alanine aminotransferase(ALT),total bilirubin(TBIL)and aspartate aminotransferase(AST)in the serum of rats were detected.HE staining microscopy was ap-plied to detect pathological changes in liver tissue.TUNEL staining microscopy was applied to detect cell apoptosis in liver tissue.Chromatin immuno-precipitation was applied to detect HBV viral load in liver tissue.ELISA was ap-plied to detect the levels of monocyte chemotactic protein-1(MCP-1),interleukin-12(IL-12),and tumor necrosis factor-α(TNF-α)in liver tissue.Western blot was applied to detect the expression of caspase-3,Bcl-2 associated X protein(Bax),p-AMPK and SIRT1 proteins in liver tissue.Results Compared with hepatitis B group,the liver damage of rats in the Gal-L group,Gal-H group and lamivudine group was alleviated;The level of serum AST,TBIL,and ALT,apoptosis rate,HBV viral load and the level of MCP-1,IL-12,TNF-α as well as the expression of caspase-3 and Bax proteins in liver tissue were all reduced.The expression of p-AMPK and SIRT1 proteins in liv-er tissue increased(P＜0.05).Compound C baffled inhibitory effects of high-dose Gal on inflammation,cell apopto-sis,and HBV viral load in liver tissue of hepatitis B rats.Conclusions The mechanism of Gal in inhibiting inflam-mation,cell apoptosis and HBV virus replication in hepatitis B rats is potentially attributed to up-regulation of the AMPK/SIRT1 pathway.

Objective:To evaluate the correlation between the degree of posterior longitudinal ligament (PLL) injury and various parameters of vertebral body injury in patients with thoracolumbar burst fractures.Methods:A total of 48 patients with thoracolumbar burst fractures were admitted to the Spine Surgery Center of the Second Affiliated Hospital of Inner Mongolia Medical University between December 2022 and January 2024. The cohort consisted of 31 males and 17 females, with a mean age of 44.1±11.8 years (range, 18-65 years). Based on the PLL injury grading method proposed by Sun Zhaoyun, patients were classified into three groups: mild, moderate, and severe. However, due to an insufficient number of patients in the severe group ( n=3), the moderate and severe groups were combined for statistical analysis, resulting in two groups: mild, and moderate-to-severe. Patient demographic and clinical data were collected. Local kyphosis (LK), inversion angle (IA), horizontal rotation angle (HRA), increased interspinous distance (IISD), anterior vertebral body compression ratio (AVBCR), posterior vertebral body compression ratio (PVBCR), middle vertebral body compression ratio (MVBCR), the ratio of height of bone fragment (RHBF), the ratio of width of bone fragment (RWBF), and mid-sagittal canal diameter compression ratio (MSDCR) were measured. Statistical analyses were performed using SPSS 25.0. Categorical variables were expressed as frequency (percentage) and analyzed using chi-square and Fisher exact tests. Continuous variables were tested for normality, with non-normally distributed data analyzed using the rank-sum test and expressed as median (interquartile range). Multivariate logistic regression analysis was performed to identify independent risk factors, and receiver operating characteristic (ROC) curves were plotted to calculate the area under the curve (AUC) to evaluate predictive performance. Results:Among the 48 patients, only 3 were found to have severe PLL injury, necessitating the combination of the moderate and severe groups for statistical purposes. Patients in the moderate-to-severe group demonstrated significantly higher AVBCR, PVBCR, RHBF, MVBCR, MSDCR, and IA compared to the mild group ( P<0.05). Multivariate logistic regression identified AVBCR, PVBCR, MSDCR, and IA as independent risk factors for moderate-to-severe PLL injury ( OR>1, P<0.05). ROC curve analysis revealed that AVBCR, PVBCR, MSDCR, IA, and their combined index could effectively predict moderate-to-severe PLL injury ( P<0.05). Notably, the combined index showed superior predictive performance (AUC=0.970) compared to individual parameters. Threshold values were determined as follows: AVBCR>45.30%, PVBCR>12.17%, MSDCR>27.13%, IA>5.90°, and the combined index >0.61, indicating PLL damage. Conclusion:AVBCR, PVBCR, MSDCR, IA, and their combined index are significantly associated with moderate-to-severe PLL injury in thoracolumbar burst fractures. The combined index demonstrates superior predictive ability compared to single parameters, providing a reliable tool for assessing PLL integrity.

Pediatric calyceal diverticulum (CD) is a relatively rare entity. Fewer cases were reported in China treated by retroperitoneal laparoscoopic surgery in children. In this paper, 2 cases of children with CD admitted to our hospital were reported. CT urography showed cystic low-density mass without obvious enhancement, and delayed contrast agent was found to enter the lesion. Both cases underwent cystoscopy + retroperitoneoscopy + diverticular neck suture. They were followed up for 15 months and 9 months after the surgery, respectively, with favorable outcomes and no recurrence of CD.
