[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.

This report presents a case of esophageal fistula with recurrent cervical abscess as the initial symptom. The patient underwent anterior cervical fracture reduction and internal fixation in 2021 due to trauma. In 2023, the patient received radiofrequency ablation for bilateral thyroid lobe lesions, after which recurrent cervical abscesses occurred over an 8-month period. Fiberoptic laryngoscopy with the biopsy channel insufflation method revealed a large esophageal fistula at the esophageal inlet. After removing the internal fixation plate, the patient received daily wound care, and serial fiberoptic laryngoscopy revealed spontaneous healing of the esophageal fistula. During the 1-year follow-up, no recurrence of cervical abscess was observed, and the esophageal fistula healed well.

The accumulation of deoxyribonucleic acid (DNA) oxidative damage mediated by reactive oxygen species (ROS) is closely associated with liver diseases. 8-Oxoguanine (8-OxoG), a prevalent DNA oxidation product, plays a significant role in liver disease progression. The base excision repair (BER) pathway, comprising over 30 proteins including 8-OxoG DNA glycosylase1 (OGG1), MutY homolog (MUTYH), and MutT homolog protein 1 (MTH1), is responsible for the clearance and mismatch repair of 8-OxoG. Abnormally high levels of 8-OxoG and dysregulated expression and function of 8-OxoG repair enzymes contribute to the onset and development of liver diseases. Consequently, targeting the 8-OxoG production and repair system with agonists or inhibitors may offer a promising approach to liver disease treatment. This review summarizes the impact of 8-OxoG accumulation and dysregulated repair enzymes on various liver diseases, including viral liver disease, alcoholic liver disease (ALD), metabolic dysfunction-associated steatotic liver disease (MASLD), cholestatic liver disease (CLD), liver fibrosis, cirrhosis, and liver cancer. Additionally, we review natural constituents as potential therapeutic agents that regulate 8-OxoG production, repair enzymes, and repair system-related signal pathways in oxidative damage-induced liver diseases.

[Objective]To investigate the effect of blue light on emmetropization in guinea pigs,explore the potential mechanisms and assess its application in myopia prevention and control.[Methods]Three-week-old male guinea pigs(n=20)were randomly assigned to the white light group and the blue light group.Refraction and ocular biological parameters were measured every 2 weeks until the experiment ended at week 8.And the 4D-data-independent acquisition(4D-DIA)proteomics technology was used to analyze retina from both the blue light and white light groups,exploring protein composition,expression differences,and biological functions.[Results]After 2 weeks,Guinea pigs exposed to white light gradually tended towards emmetropia,showing a statistically significant difference in refractive error compared to the blue light group(P<0.001).From week 4,the axial length of the blue light group was significantly shorter than that of the white light group(P<0.05).Meanwhile,the vitreous chamber length in the blue light group was significantly smaller than that of the white light group from week 2(P<0.05).A total of 161 differentially expressed proteins were identified by proteomics technology in the retina,with 98 proteins upregulated and 63 proteins downregulated.These proteins were primarily enriched in biosynthetic pathways such as vesicle transport,redox reaction,niacin and nicotinamide metabolism and NAD+metabolism.[Conclusions]Guinea pigs raised under blue light exhibit hyperopic drift and slowed axial elongation,which slows the procession of emmetropization.Based on the 4D-DIA technology,the differentially expressed proteins between the blue light and white light groups are primarily involved in NAD+metabolism,niacin and nicotinamide metabolism.Especially in NAD+salvage synthesis,nicotinamide phosphoribosyl transferase(NAMPT)is upregulated,while sirtuin 2(SIRT2)is downregulated.It provides new insights into the mechanism of blue light in emmetropization and a theoretical basis for myopia prevention and control.

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 analyze the clinical characteristics of lung adenocarcinoma patients with positive EGFR mutations detected in pleural effusion.Methods We retrospectively analyzed the clinical characteristics including gender,age,smoking history,presence of other underlying diseases(such as COPD,cardiovascular disease,and diabetes),site of pleural fluid,feature of pleural fluid,and TNM stage in patients with lung adenocar-cinoma who had been admitted to the first Affiliated Hospital of Bengbu Medical College from 2020.01 to 2022.12 for the first time by the detection of EGFR mutation positive in pleural effusion.The data were statistically analyzed using the SPSS 26.0 software.Results A total of 126 patients were screened for enrollment,including 61 patients(48.41%)with EGFR exon 19 deletion mutation(19del),56 patients(44.44%)with exon 21 L858R mutation(21L858R),and 9 patients(7.14%)with non-classical mutations.Univariate analysis showed that the three muta-tion subtypes were statistically significant in terms of gender,age,smoking history,and presence of COPD(P<0.05 for all comparisons),but not in terms of pleural fluid site,feature of pleural fluid,tumor size,and presence of cardiovascular disease,diabetes mellitus,presence of distant metastases,and mediastinal lymph node metastases(P>0.05 for all comparisons);Multivariate analysis showed that 21 L858R mutation was more likely to be found in male,older age,non-smoking,and presence of COPD than 19del mutation;non-classical mutation was more likely to be found in male than 19del mutation.Conclusions There are significant differences among the three mutation subtypes in sex,age,smoking history,and presence of COPD,but not in pleural fluid location,feature of pleural fluid,tumor size,presence of cardiovascular disease or diabetes mellitus,presence of distant metastases,or medias-tinal lymph node metastases;Among lung adenocarcinoma patients with positive EGFR mutations in pleural fluid,21 L858R mutation mostly occurs in male,older age,non-smokers,and those complicated with COPD,while non-classical mutation mainly develops in male.However,more case studies are needed to confirm the above conclusions.

Objective To explore the molecular mechanism by which FEZF1-AS1 overexpression promotes progression of non-small cell lung cancer(NSCLC)via the miR-130a-5p/CCND1 axis.Methods TCGA database was used to analyze FEZF1-AS1 expression levels in NSCLC.FEZF1-AS1 expression was detected by qRT-PCR in clinical specimens of NSCLC tissues and NSCLC cell lines,and its correlation with clinical features of the patients were analyzed.The binding sites of FEZF1-AS1 with hsa-miR-130a-5p and those of hsa-miR-130a-5p with CCND1 were predicted.CCK8 assay,clone formation assay,scratch assay,and Transwell assay were employed to examine the effects of FEZF1-AS1 knockdown and hsa-miR-130a-5p inhibitor on proliferation,invasion,and migration abilities of lung cancer cell lines.Dual luciferase assay was used to verify the binding of FEZF1-AS1 with hsa-miR-130a-5p and the binding of hsa-miR-130a-5p with CCND1.Western blotting was performed to detect the changes in CCND1 protein expression level in H1299 and H358 cells following FEZF1-AS1 knockdown and treatment with hsa-miR-130a-5p inhibitor.Results FEZF1-AS1 was highly expressed in NSCLC tissues in close correlation with lymph node metastasis and also in H1299 and H358 cell lines(all P<0.05).FEZF1-AS1 knockdown obviously reduced proliferation,migration,and invasion abilities of NSCLC cells(P<0.05).Dual luciferase assay confirmed the binding of hsa-miR-130a-5p with FEZF1-AS1 and CCND1(P<0.05),and hsa-miR-130a-5p inhibitor significantly inhibited proliferation,migration,and invasion of NSCLC cells(P<0.05).FEZF1-AS1 knockdown significantly reduced CCND1 protein expression in NSCLC cells,and this effect was strongly inhibited by treatment with hsa-miR-130a-5p inhibitor(P<0.05).Conclusion FEZF1-AS1 is highly expressed in NSCLC tissue in close correlation with lymph node metastasis to promote cancer progression through the miR-130a-5p/CCND1 axis.

Objective This study aims to provide craniofacial features and incisor position prediction models among esthetics population after orthodontic treatment.Methods A total of 338 patients with esthetic profiles were se-lected from 1 055 post-orthodontic adults based on inclusion and exclusion criteria and scored by five dental students.Mean values of cephalometric measurement were demonstrated with gender and sagittal skeletal pattern(ANB)differ-ences assessed by generalized estimating equation.Correlations among age,skeletal,and soft tissue variables in differ-ent genders were determined.Multivariate analysis was used to assess the influence of skeletal and soft tissue variables on orthodontic incisor position.Results Within the esthetic cohort after orthodontic treatment,gender differences ex-isted in cranial and mandibular length,mandibular rotation,protrusion of pogonion,inclination of maxillary incisors,upper lip thickness,lower 1/3 face height,and nose protrusion.However,in class Ⅰ malocclusion,the development of the chin showed no significance,whereas the protrusion of the lower lip significantly differed between genders,with less protrusion in males.In males,the protrusion of lip and chin varied among groups,with thinner basic upper lip thick-ness of class Ⅱ than class Ⅰ and greater lower lip height of class Ⅲ than class Ⅰ.In females,the protrusion and height of the upper lip and chin varied in groups,with thicker basic upper lip thickness of class Ⅲ than class Ⅰ.Upper lip thickness,female basic upper lip thickness,and female lower lip height were correlated with age.The protrusion of the upper lip was mainly correlated with posterior cranial base,mandibular body length,ANB in male and SNA,ANB,sag-ittal maxillary length,mandibular rotation,and protrusion of pogonion in female.The protrusion of the lower lip in males was mainly correlated with ramus height,mandibular rotation,protrusion of pogonion in male and ANB,mandib-ular rotation,and protrusion of pogonion in females.After employing skeletal variables to fit dental parameters,optimal results were achieved in male IMPA(adjusted R2=0.712)and female G Vert-U1(adjusted R2=0.795).After employing skeletal and soft tissue variables simultaneously,optimal results were achieved in male and female G Vert-U1,which was mainly influenced by the protrusion of the chin and nasal base in males(adjusted R2=0.836)and the protrusion of the nasal base as well as ANB in females(adjusted R2=0.842).Conclusion This study demonstrated the craniofacial features of esthetics population after orthodontic treatment and revealed the correlation of gender,age,skeleton,and soft tissues to provide reliable prediction models for aesthetic orthodontic incisor position.
