Objective:To explore the influencing factors for pathological upgrading in prostate cancer patients with a Gleason score of 3 + 3 undergoing targeted biopsy,and to establish a nomogram prediction model.Methods:A retrospective analysis was conducted on 191 patients with localized prostate cancer diagnosed with a Gleason score of 3 + 3 through targeted biopsies at the First Affiliated Hospital of Nanjing Medical University from January 2020 to June 2024. The age of the patients was 67(61,73)years,with prostate-specific antigen(PSA)level of 7.44(5.53,10.19)ng/ml,prostate volume of 35.64(26.59,48.97)ml,and PSA density(PSAD)of 0.20(0.14,0.31)ng/ml 2. Among them,61 cases(31.94%)had a Prostate Imaging Reporting and Data System(PI-RADS)score of 3,104 cases(54.45%)had a score of 4,and 26 cases(13.61%)had a score of 5. The diameter of the main lesion was 10.75(7.86,14.00)mm. The lesions were located in the peripheral zone in 78 cases(40.84%),the transition zone in 99 cases(51.83%),and the anterior fibromuscular stroma in 14 cases(7.33%). The lesions were found at the apex in 56 cases(29.32%),in the body in 120 cases(62.83%),and at the base in 15 cases(7.85%). MRI revealed only one lesion with a PI-RADS score ≥ 3 in 131 cases,two suspected lesions in 43 cases,three suspected lesions in 12 cases,and four suspected lesions in 5 cases. Systematic biopsy was positive in 121 cases(63.4%)and negative in 70 cases(36.6%). The lesions were confined to the left lobe in 63 cases(32.98%),right lobe in 68 cases(35.60%),and involved both lobes in 60 cases(31.41%). The interval between biopsy and surgery was 9.0(7.0,14.0)days. Univariate analyses were performed using Mann-Whitney U tests or χ2 tests,and multivariate logistic regression was used to identify independent predictors of pathological upgrading. A nomogram model was constructed based on these independent predictors. The model’s discriminative ability was assessed using the area under the receiver operating characteristic(ROC)curve(AUC),and internal validation of the model’s consistency was conducted using the bootstrap resampling method. Decision curve analysis(DCA)was performed to assess clinical utility. Results:Among the 191 cases,60(31.4%)had no pathological upgrading after surgery,while 131(68.6%)showed upgrading. Univariate analysis showed that the maximum diameter of the main lesion[9.0(6.0,13.2)mm vs. 11.0(8.4,14.0)mm],number of suspicious lesions on MRI[1.0(1.0,1.0)vs. 1.0(1.0,2.0)],number of positive systematic biopsy cores[1.0(0,2.0)vs. 1.0(0,3.0)],percentage of positive systematic biopsy cores[0.08(0,0.17)vs. 0.12(0,0.25)],number of positive targeted biopsy cores[2.0(1.0,3.0)vs. 3.0(1.0,4.0)],percentage of positive targeted biopsy cores[0.37(0.24,0.75)vs. 0.50(0.38,0.85)],level of the index lesion,location of the index lesion,and PI-RADS score were associated with pathological upgrading( P < 0.05). Multivariate logistic regression analysis showed that PI-RADS score 4( OR = 5.88,95% CI 2.41 - 14.35),number of suspicious lesions on MRI( OR = 4.15,95% CI 1.88 - 9.17),location of the index lesion in the transition zone( OR = 6.86,95% CI 2.81 - 16.73),and percentage of positive targeted biopsy cores( OR = 4.37,95% CI 1.38 - 14.90)were independent risk factors for pathological upgrading( P < 0.05). The nomogram model constructed using these predictors had an AUC of 0.845. Internal validation using the Bootstrap method yielded an AUC value of 0.812,indicating high predictive accuracy of the model. The calibration curve indicated good calibration. Decision curve analysis showed that the threshold range for net benefit in the model was between 12% - 100%. Conclusions:The PI-RADS score 4,the number of lesions with PI-RADS ≥ 3,the location of the main lesion in the transition zone,and the percentage of positive needles in targeted biopsy are independent risk factors for pathological upgrading from Gleason score 3 + 3. The nomogram model constructed from these factors demonstrates good predictive performance and provides a reference for clinical decision-making.

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder and its symptoms are subject to the composition of the gut microbiota. However, it is not yet clear how probiotics relieve IBS, and there is no well-acknowledged standards concerning the clinical application of probiotics. This systematic review was conducted on the literature published from January 2020 to December 2023 and included 12 randomized controlled trials on probiotics in the treatment of IBS. Compared with placebo, the probiotic preparations improved the overall efficacy in IBS patients and was also well tolerated, suggesting the potential of probiotics in IBS management. Nevertheless, different probiotic strains, dosages, combinations, and dosing schedules may affect the outcomes. In the future, large-scale, multi-center, long-term follow-up studies are still needed to clarify the effective strains and methods of use and to promote the use of probiotics in the treatment of IBS.

Objective:To investigate the efficacy and assess the safety of transnasal nebulisation of budesonide in children with adenoid hypertrophy. Methods:Children with adenoid hypertrophy who attended the Children's Hospital of Zhejiang University School of Medicine between December 2021 and December 2022 were randomly assigned to budesonide high-dose group(Group A: budesonide 1 mg/dose + saline nasal rinse), budesonide low-dose group(Group B: budesonide 0.5 mg/dose + saline nasal rinse), and control group(Group C: saline nasal rinse), and each group 20 children were collected separately, The efficacy and safety of transnasal nebulisation of budesonide in children with adenoid hypertrophy were assessed by comparing the symptomatic VAS scores, adenoidal nasopharyngeal lateral radiographs A/N values, nocturnal sleep oximetry(SaO2), and the incidence of adverse events during the treatment period of 8-week in the three groups. Results:The 8-week baseline differences in adenoid A/N values were statistically different between groups A and B(P<0.001) and A and C(P=0.022), with the reduced amount in adenoid volume being most pronounced in group A, which differed from the other two groups. With the increase of intervention time, SaO2 levels gradually increased(F=154.725, P<0.001) and VAS scores gradually decreased(F=165.616, P<0.001) in all three groups. After 8 weeks of treatment, there was no statistically significant difference in SaO2 level(P=0.085) between groups A and B. There was a statistically significant difference in VAS total scores between Group A and Group B (P < 0.05) . The improvement of SaO2and total VAS score in group A was higher than that in group B. There was a statistically significant difference in the comparison of SaO2 level and total VAS score between groups A and B, and between groups A and C(P<0.01); after the intervention of the three groups, showing the greatest improvement of total VAS score and SaO2in the group A, followed by Group B. There was no statistically significant difference in the incidence of adverse events among Groups A, B, and C throughout the trial. Conclusion:The treatment of children with adenoid hypertrophy by intranasal nebulisation of budesonide suspension has good efficacy and safety, which is conducive to reducing the size of adenoids, improving the clinical symptoms of children with adenoid hypertrophy, and improving the SaO2of nocturnal sleep, and it has a certain clinical application value.

ObjectiveTo observe the mechanism of Jiawei Guizhi Fuling decoction (JGFD) in alleviating sciatic nerve injury in painful diabetic peripheral neuropathy (PDPN) rats by regulating mitophagy through the PTEN-induced putative kinase 1 (PINK1)/Parkin signaling pathway. MethodThe PDPN model was established by intraperitoneal injection of streptozotocin (STZ). After modeling, the rats were randomly divided into JGFD high, medium, and low dose groups (JGFD-H, JGFD-M, JGFD-L; 39.6, 19.8, 9.9 g·kg-1·d-1, respectively), a positive drug group (lipoic acid capsules, LA; 50 mg·kg-1·d-1), and a model group (PDPN). A blank control group (CON) was established. Drug intervention was administered continuously for 8 weeks after modeling. Measurements included body weight and fasting blood glucose of PDPN rats at weeks 0, 2, 4, and 8, mechanical pain threshold and thermal pain threshold at weeks 0 and 8, and motor nerve conduction velocity at week 8. Hematoxylin-eosin (HE) staining was used to observe the morphology of sciatic nerve tissue. The ultrastructure of mitochondria and autophagosomes was observed by transmission electron microscopy. Western blot was performed to detect the protein expression levels of PINK1, Parkin, p62, Beclin-1, and LC3 in sciatic nerve tissue. Additionally, real-time quantitative PCR (Real-time PCR) was performed to detect the mRNA expression levels of PINK1, Parkin, p62, Beclin-1, and LC3 in sciatic nerve tissue. ResultCompared with the CON group, the PDPN group showed a significant decrease in body weight at all time points, a significant increase in fasting blood glucose, significantly shortened mechanical pain and thermal pain thresholds, and significantly reduced motor nerve conduction velocity. The protein and mRNA expression of PINK1, Parkin, Beclin-1, and microtubule-associated protein light chain 3(LC3) in sciatic nerve tissue was significantly reduced, while p62 protein and mRNA expression was significantly increased (P<0.01). Pathological changes included edema of sciatic nerve fibers, segmental demyelination, loose and disordered arrangement of the myelin sheath layers, significant swelling of mitochondria, reduced electron density, disappearance of cristae, and absence of typical autophagosome and autolysosome structures. Compared with the PDPN group, each JGFD dose group showed a significant increase in body weight and a significant reduction in fasting blood glucose (P<0.05, P<0.01). The mechanical pain threshold and thermal pain threshold were significantly prolonged, and motor nerve conduction velocity was significantly increased across all JGFD and LA groups. The expression levels of PINK1, Parkin, Beclin-1, and LC3 proteins and mRNA in sciatic nerve tissue were significantly increased, while p62 protein and mRNA expression levels were significantly decreased (P<0.05, P<0.01). Pathological damage to the sciatic nerve was alleviated to varying degrees, with a relatively intact myelin sheath morphology and intact or slightly edematous outer mitochondrial membrane. Autophagolysosome structures were observed in the JGFD-M and JGFD-H groups. Compared with the LA group, the JGFD-H group showed a significant increase in body weight, a significant reduction in fasting blood glucose, a significant increase in motor nerve conduction velocity, a significant increase in PINK1 protein expression and PINK1, Parkin, and Beclin-1 mRNA expression in sciatic nerve tissue, and a significant decrease in p62 mRNA expression (P<0.05, P<0.01). ConclusionJGFD may alleviate sciatic nerve injury in PDPN rats by activating mitophagy through the regulation of the PINK1/Parkin signaling pathway.

A retrospective analysis was conducted on 5 516 patients diagnosed with prostate cancer(PCa) at our hospital. Among these, 52 patients aged ≤ 50 years were defined as the early-onset group.For the control group, 228 patients aged >50 years were randomly selected at a ratio of 1∶4.4. The early-onset group predominantly presented with elevated PSA levels at diagnosis and had a lower positive rate of digital rectal examination. There were no significant differences in clinical and pathological characteristics between the early-onset group and the control group. Young PCa patients in the low to intermediate risk categories had similar survival prognosis to older patients. However, young patients with high-risk prostate cancer had 5-year progression-free survival rate of 38.4% compared to 55.6% for older patients, and 5-year cancer-specific survival rate of 70.1% compared to 84.1% for older patients, indicating that high-risk young patients exhibited poorer oncological outcomes.

ObjectiveTo explore the mechanism of Gancao Fuzitang (GCFZ)in inhibiting the bone destruction of collagen-induced arthritis (CIA) model in mice. MethodThirty male DBa/1J mice were randomly divided into normal group, CIA group, low-dose GCFZ group (GCFZ-L, 2.4 g·kg-1), high-dose GCFZ group (GCFZ-H, 4.8 g·kg-1), and methotrexate group (MTX, 1 mg·kg-1), with six mice in each group. The CIA model was induced by secondary immunization method. The arthritis index of mice in each group was observed and recorded, and the histopathological changes in ankle joint were observed by hematoxylin-eosin (HE) staining. The damage to ankle cartilage was detected by safranin O-fast green staining. Micro-CT scanning was used to detect the bone destruction of ankle joint, and the expression of nuclear factor-κB p65 (NF-κB p65), p-NF-κB p65, inhibitory-κB kinase α/β (IKKα/β), and p-IKKα/β was observed by immunohistochemical staining. ResultCompared with the normal group, the CIA group showed manifest joint swelling and increased arthritis index score (P<0.01). Compared with the CIA group, the groups with drug intervention could inhibit joint swelling and reduce arthritis index score (P<0.05, P<0.01). As revealed by HE staining and safranine O-green staining, compared with the CIA group, the groups with drug intervention could inhibit synovial invasion and reduce the destruction of articular cartilage. Micro-CT scanning analysis showed that compared with the CIA group, the GCFZ-H group and the MTX group showed reduced bone destruction scores (P<0.01). The immunohistochemical results showed that compared with the normal group, the CIA group showed increased optical density values of NF-κB p65, p-NF-κB p65, IKKα/β, and p-IKKα/β(P<0.01). Compared with the CIA group, the GCFZ-H group and the MTX group showed reduced optical density values of NF-κB p65, p-NF-κB p65, IKKα/β, and p-IKKα/β(P<0.05,P<0.01). In the GCFZ-L group, only the NF-κB p65 optical density value decreased(P<0.01). ConclusionGCFZ may inhibit bone destruction in CIA mice by regulating the NF-κB signaling pathway.

Background Nitrosamines (NAms) are highly carcinogenic and frequently detected in drinking water systems in China, indicating potential human health risk through drinking water. Objective To analyze the distribution of NAms in drinking water in Shanghai and to evaluate relevant human health risk. Methods A total of 94 samples of source water and 120 samples of finished water were collected in February (dry period) and August (wet period) of 2021 from 30 drinking water plants in Shanghai, and eight NAms were quantitatively analyzed by gas chromatography tandem mass spectrometry after solid phase extraction. Cancer risks for different age groups caused by NAms exposure through water were evaluated using Monte Carlo probabilistic method and carcinogens risk assessment model recommended by the United States Environmental Protection Agency. Results The concentrations of total NAms in source and finished water were 12.56-65.86 ng·L−1 and 8.52-57.38 ng·L−1, respectively. The average concentration of total NAms was higher in source water (33.50 ng·L−1) than in finished water (22.07 ng·L−1, P<0.05) during dry season, and lower in source water (16.90 ng·L−1) than in finished water (21.02 ng·L−1, P<0.05) during wet season. The average concentration of total NAms in source water during dry season was twice of that during wet season. The positive rate of N-nitrosodimethylamine (NDMA) was the highest (100%) among the eight NAms. The cancer risk of exposure to NAms in finished water in Shanghai was mainly from the ingestion route, which was mostly caused by NDMA. The cancer risk from exposure to NAms in water for children (median=4.32×10−5) was slightly higher than that for adults (median=3.34×10−5) and adolescents (median=2.27×10−5). The cancer risks of exposure to NAms in water for people of different ages were mainly (80% - 95%) at an acceptable level (1×10−6 - 1×10−4). Conclusion NAms contamination is positive in Shanghai’s drinking water and NDMA is the main contaminant. The removal of NAms in water by current water treatment process is season-dependent. The cancer risk of children exposed to NAms in water was slightly higher than that of adults and adolescents, but all at acceptable levels.
