The choice of biopsy method is critical in diagnosing prostate cancer (PCa). This retrospective cohort study compared systematic biopsy (SB) or cognitive fusion-targeted biopsy combined with SB (CB) in detecting PCa and clinically significant prostate cancer (csPCa). Data from 2572 men who underwent either SB or CB in Fudan University Shanghai Cancer Center (Shanghai, China) between January 2019 and December 2023 were analyzed. Propensity score matching (PSM) was used to balance baseline characteristics, and detection rates were compared before and after PSM. Subgroup analyses based on prostate-specific antigen (PSA) levels and Prostate Imaging-Reporting and Data System (PI-RADS) scores were performed. Primary and secondary outcomes were the detection rates of PCa and csPCa, respectively. Of 2572 men, 1778 were included in the PSM analysis. Before PSM, CB had higher detection rates for both PCa (62.9% vs 52.4%, odds ratio [OR]: 1.54, P < 0.001) and csPCa (54.9% vs 43.3%, OR: 1.60, P < 0.001) compared to SB. After PSM, CB remained superior in detecting PCa (63.1% vs 47.9%, OR: 1.86, P < 0.001) and csPCa (55.0% vs 38.2%, OR: 1.98, P < 0.001). In patients with PSA 4-12 ng ml -1 (>4 ng ml -1 and ≤12 ng ml -1 , which is also applicable to the following text), CB detected more PCa (59.8% vs 40.7%, OR: 2.17, P < 0.001) and csPCa (48.1% vs 27.7%, OR: 2.42, P < 0.001). CB also showed superior csPCa detection in those with PI-RADS 3 lesions (32.1% vs 18.0%, OR: 2.15, P = 0.038). Overall, CB significantly improves PCa and csPCa detection, especially in patients with PSA 4-12 ng ml -1 or PI-RADS 3 lesions.

OBJECTIVE: To investigate the relationship between serum levels of fibroblast growth factor-23 (FGF-23), heparanase (HPSE) and early renal impairment (RI) in patients with multiple myeloma (MM). METHODS: A retrospective analysis was conducted on the clinical data of 125 MM patients who were initially diagnosed in the Department of Hematology of the First Affiliated Hospital of Baotou Medical College, Inner Mongolia University of Science and Technology from June 2020 to June 2023. The patients were divided into RI group (>176.80 μmol/L) and non-RI group (≤176.80 μmol/L) based on their serum creatinine levels when diagnosed. The baseline data and laboratory indexes of the two groups were compared. The relationship between serum FGF-23, HPSE and early RI in MM patients was analyzed. RESULTS: Among 125 newly diagnosed MM patients, 33 cases developed early RI, accounting for 26.40%. The proportion of light chain type, blood urea nitrogen (BUN), blood uric acid, lactate dehydrogenase, FGF-23, and HPSE levels in RI group were higher than those in non-RI group (all P <0.05). There was no statistical significant difference in other data between the two groups (P >0.05). Multivariate logistic regression analysis showed that BUN, FGF-23 and HPSE were associated with early RI in MM patients (all P <0.05). The serum FGF-23 level was divided into Q1-Q4 groups by quartile, and the serum HPSE level was divided into q1-q4 groups. The correlation analysis showed that with the increase of serum FGF-23 and HPSE levels, the incidence of early RI increased (r =0.668, 0.592). Furthermore, logistic regression analysis showed that after controlling for confounding factors, elevated levels of serum FGF-23 and HPSE were still influencing factors for early RI in MM patients (OR>1, P <0.05). According to Pearson's linear correlation test, there was a positive correlation between serum FGF-23 level and HPSE level (r =0.373). CONCLUSION There is a certain correlation between serum levels of FGF-23, HPSE and early RI in MM patients, and the incidence of early RI is higher in patients with abnormally high levels of both.

Ovarian tumor (OT) is the most lethal form of gynecologic malignancy, with minimal improvements in patient outcomes over the past several decades. Metastasis is the leading cause of ovarian cancer-related deaths, yet the underlying mechanisms remain poorly understood. Psychological stress is known to activate the glucocorticoid receptor (NR3C1), a factor associated with poor prognosis in OT patients. However, the precise mechanisms linking NR3C1 signaling and metastasis have yet to be fully elucidated. In this study, we demonstrate that chronic restraint stress accelerates epithelial-mesenchymal transition (EMT) and metastasis in OT through an NR3C1-dependent mechanism involving nuclear protein 1 (NUPR1). Mechanistically, NR3C1 directly regulates the transcription of NUPR1, which in turn increases the expression of snail family transcriptional repressor 2 (SNAI2), a key driver of EMT. Clinically, elevated NR3C1 positively correlates with NUPR1 expression in OT patients, and both are positively associated with poorer prognosis. Overall, our study identified the NR3C1/NUPR1 axis as a critical regulatory pathway in psychological stress-induced OT metastasis, suggesting a potential therapeutic target for intervention in OT metastasis.

Objective:To analyze the factors associated with non-radiographic bone erosion in gout pa-tients,to improve the understanding of bone erosion in gout,and to promote the early detection of bone erosion.Methods:A retrospective analysis was conducted on the medical records of gout patients treated at Beijing Jishuitan Hospital from January 2018 to January 2022.Bone erosion was detectable by ultra-sound but not detected by X-ray as non-radiographic bone erosion;no bone erosion was detected by both ultrasound and joint X-ray as undetected bone erosion.A case-control study was used,and the two groups were matched 1∶2 according to age and sex.The differences between the two groups were com-pared in terms of general information,joint involvement characteristics,laboratory indicators and compli-cations.In the univariate analysis,P＜0.1 was included in the multivariate analysis,and the conditional Logistic regression was used for the multivariate analysis.P＜0.05 was considered to have statistically significant differences.Results:Among the 41 patients with non-radiographic bone erosion,the top three joints with bone erosion before its occurrence were metatarsophalangeal joint(12 cases),ankle(10 ca-ses),and knee(7 cases).There were 82 patients undetected with bone erosion.There were no signifi-cant differences in general information between the two groups(P＞0.05),including age,gender,body mass index,and alcohol consumption history.The characteristics of affected joints in the non-radio-graphic bone erosion group were compared with those in the no bone erosion detected,and the former had more affected joints(P=0.02),and a higher proportion of patients with at least 3 attacks of gout per year(P＜0.001).There were no significant differences in serum uric acid,fasting blood glucose,cholesterol,triglycerides,low-density lipoprotein,high-density lipoprotein,creatinine,homocysteine,white blood cell count,and urine pH between the two groups(P＞0.05).The results of multivariate analysis showed that at least 3 flares of gout per year was an independent risk factor for radiologically negative bone erosion in patients with gout,with an OR(95％CI)of 5.139(1.529-17.271).Conclusion:At least 3 flares of gout per year predicts the occurrence of radiologically negative bone erosion,and these patients should be given more attention to achieving treatment targets.

Objective To investigate the correlation between the expression of serum microRNA-21-5p(miR-21-5p),microRNA-1224-5p(miR-1224-5p),and microRNA-181a-5p(miR-181a-5p)with postoperative delayed healing in patients with femoral neck fracture(FNF).Methods From October 2021 to April 2024,371 patients with FNF admitted to our hospital were included as subjects.The patients were assigned into a study group(delayed healing,68 cases)and a control group(normal healing,303 cases)based on whether the fracture ends healed 4 months after surgery.Real-time fluorescence quantitative PCR(qRT-PCR)was applied to detect the expression levels of serum miR-21-5p,miR-1224-5p,and miR-181a-5p.Multivariate Logistic regression was applied to analyze the influencing factors of postoperative healing delay in FNF patients.ROC curve was applied to analyze the predictive value of serum miR-21-5p,miR-1224-5p,and miR-181a-5p for postoperative healing delay in FNF patients.Results The levels of serum miR-21-5p,miR-1224-5p,and miR-181a-5p in the study group were lower than those in the control group(P＜0.05).Multivariate Logistic analysis showed that age ≥ 60 years old,diabetes,and smoking were risk factors for postoperative delayed healing in FNF patients(P＜0.05),and miR-21-5p,miR-1224-5p and miR-181a-5p were protective factors for postoperative delayed healing in FNF patients(P＜0.05).ROC curve showed that the AUC values of miR-21-5p,miR-1224-5p,and miR-181a-5p for predicting postoperative healing delay in FNF patients were 0.845,0.809,and 0.797,respectively.When the three were combined for prediction,the AUC increased to 0.933.The combined detection effect of the three indicators was better than that of any individual indicator(Zcombination vs.miR-21-5p=3.444,Zcombination vs.miR-1224-5p=4.401,Zcombination vs.miR-181a-5p=4.279,P＜0.05).Conclusion The levels of serum miR-21-5p,miR-1224-5p,and miR-181a-5p are reduced in FNF patients with postoperative delayed healing.The combined detection of the three may have a certain predictive value for postoperative delayed healing in FNF patients.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
