Objective To compare the efficacy and safety of the transperineal four-hole prostate puncture with conventional transperineal prostate puncture. Methods A total of 91 patients undergoing transperineal prostate puncture at the Second Hospital of Hebei Medical University during Jan. 2024 and Jan. 2025 were enrolled. Based on the puncture methods, the patients were divided into the four-hole group(n=46)and conventional group(n=45). The four-hole group underwent four-hole puncture, while the conventional group received standardized parallel needle insertion. The operation time, intraoperative blood loss, pain score, positive biopsy rate, and complications were compared between the two groups. Results The intraoperative blood loss [(7.05±2.48)mL vs.(9.15±3.49)mL] and pain score [(2.33±1.55)vs.(3.02± 1.54)] of the four-hole group were significantly lower than those of the conventional group(P＜0.05). No significant differences were observed in the positive biopsy rate [47.8%(22/46)vs. 46.7%(21/45)] or operation time [(18.83±2.49)min vs.(18.07±1.66)min](P＞0.05). The total complication rate in the four-hole group was significantly lower than that in the conventional group [21.7%(10/46)vs. 42.2%(19/45), P＜0.05]. Conclusion Compared with the conventional parallel needle insertion method, the four-hole puncture technique reduces the intraoperative blood loss, alleviates trauma severity and pain response, and reduces the complication rate.

Based on a letrozole-induced rat model of polycystic ovary syndrome (PCOS), serum metabolomics was employed to characterize metabolic abnormalities, identify potential biomarkers, and investigate their roles in the pathogenesis and progression of PCOS. Metabolomic analyses revealed significantly decreased levels of cholesterol, pregnenolone, leucine, and citrate in the serum of model rats, accompanied by elevated levels of androsterone glucuronide (ADTG) and linoleic acid, indicating dysregulation of key pathways including steroid biosynthesis, branched-chain amino acid metabolism, tricarboxylic acid (TCA) cycle, and lipid metabolism. To elucidate the tissue origins and molecular mechanisms underlying these metabolic alterations, ovarian proteomics and qRT-PCR analyses were further integrated. The results confirmed the upregulation of key enzymes involved in the related metabolic pathways, such as 17α-hydroxylase (CYP17A1), 11β-hydroxysteroid dehydrogenase (HSD11B1), branched-chain amino acid aminotransferase (BCAT2), fatty acid desaturase 2 (FADS2), and oxoglutarate dehydrogenase (OGDH). These findings suggest that both “cholesterol precursor depletion-androgen accumulation” and “energy/lipid metabolic reprogramming” constitute core features of metabolic disturbances in PCOS. Through multi-omic cross-validation, six serum metabolites with high stability and clinical translational potential were identified as promising combinational biomarkers for the auxiliary diagnosis of PCOS. This study employed a metabolomics-guided strategy, supported by proteomic and transcriptomic validation, which has not only deepened our understanding of PCOS metabolic mechanisms but also provided us with a theoretical foundation for its auxiliary diagnosis.

Objective:To assess the preliminary efficacy and safety of modified Société Internationale d′Oncologie Pédiatrique Epithelial Liver Tumor Study Group (SIOPEL)-4 protocol for pediatric hepatoblastoma (HB) with lung metastases.Methods:This prospective cohort study enrolled 27 newly diagnosed pediatric HB with lung metastases who received the modified SIOPEL-4 protocol at Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine, and Shanghai Children′s Hospital between January 2020 to December 2023. Clinical characteristics, lung response rates to induction chemotherapy, treatment outcomes, prognostic factors and sever chemotherapy toxicities at different stages were analyzed. Survival analysis was performed by Kaplan-Meier method. Univariate prognostic analysis was conducted by Log-Rank test.Results:Of the 27 patients, there were 17 males and 10 females, with the age of 21 (15, 33) months. During the follow-up of 31 (12, 45) months for 17 continuous complete remission patients, 4 cases disease progression (2 cases death) and 6 cases relapse were observed. The 2-year event free survival (EFS) and overall survival (OS) rate was (58±11)% and (89±7)%, respectively. All the 27 patients had response to block 1-3 induction chemotherapy (cisplatin+doxorubicin), with 14 cases (52%) achieving complete response and 13 cases (48%) achieving partial response of lung metastatic lesions, the 2-year EFS rate was (81±12)% and (34±14)%, respectively ( χ 2=6.76, P=0.009), the 2-year OS rate was 100% and (79±13)%, respectively ( χ2=2.12, P=0.145). Patients with caudate lobe tumors or ≥10 pulmonary metastatic nodules had significantly lower EFS rates ( χ2=5.36, 7.84, P=0.021, 0.005, respectively). The incidence of grade 3/4 neutropenia after block 1-3 induction chemotherapy, CD (carboplatin+doxorubicin), and VI (vincristine+irinotecan) consolidation chemotherapy was 90% (73/81), 75% (58/77), and 31% (11/35), respectively. The incidence of grade 3/4 thrombocytopenia was 77% (62/81), 69% (53/77), and 14% (5/35), respectively. The incidence of grade 3/4 infections was 64% (52/81), 25% (19/77), and 20% (7/35), respectively. The differences between the groups were statistically significant ( χ2=43.51, 42.69, 33.00, all P<0.001). Two patients (10%) of the 20 evaluable patients for ototoxicity occurred grade 3 and higher hearing impairment, with 1 patient requiring a hearing aid. Conclusions:The modified SIOPEL-4 regimen shows good preliminary efficacy and safety in treating pediatric HB with lung metastases. The prognosis for patients with residual lesions in the lungs after induction chemotherapy needs to be improved. Attention should be given to the ototoxicity induced by high-dose cisplatin chemotherapy.

Fracture of humeral capitellum (FHC) in children is often detected on the coronal plane of the distal humerus.It is an intra-articular fracture, often a Salter-Harris type Ⅲ epiphyseal fracture, which is extremely rare in clinical practice and accounts for only about 1% of elbow fractures in children.This type of fracture tends to extend medially involving the trochlea, so it is also known as capitellar trochlea fracture.The rarity of this fracture makes it difficult to differentiate it from other elbow fractures on X-ray, which finally leads to miss-diagnosis or misdiagnosis as epicondylar humerus fracture or intercondylar fracture, etc.Since FHC is an intra-articular and epiphyseal fracture, inappropriate treatment will results in irreversible consequences, so the diagnosis and treatment of FHC in children are challenging.Currently, there are few studies on FHC in children, and most of related studies are case reports.Therefore, the classification and treatment of FHC in children are performed based on only the experience of FHC treatment in adults.Incisional reduction and internal fixation is the preferred treatment for most FHC children, but the efficacy of this treatment lacks the support of controlled studies with a large sample size.The mechanism of injury, staging, diagnosis, treatment, postoperative rehabilitation, and complications of pediatric FHC were reviewed in this paper to improve clinicians' understanding of pediatric FHC.

Objective:To investigate the independent and combined effects of maternal smoking during pregnancy and offspring genetic susceptibility on overall cancer mortality.Methods:Based on the United Kingdom Biobank ( n=419 228) data, the Cox proportional hazard regression model was used to estimate the effect of maternal smoking during pregnancy on offspring overall cancer (including 16 cancers in men and 18 in women) mortality and its combined effect and interaction with offspring genetic factors. Results:Maternal smoking during pregnancy was significantly associated with a 13% increased risk of overall cancer mortality in men [hazard ratio( HR)=1.13, 95% CI: 1.06-1.20] and 19% increased risk in women ( HR=1.19, 95% CI: 1.11-1.27). Participants with high genetic risk had the highest overall cancer mortality than those with low genetic risk (men: HR=1.42, 95% CI: 1.30-1.55; women: HR=1.38, 95% CI: 1.25-1.52). Compared with participants without maternal smoking during pregnancy and low genetic risk, those with maternal smoking during pregnancy and high genetic risk were associated with a 56% increased risk of overall cancer mortality in men ( HR=1.56, 95% CI: 1.37-1.77) and 59% in women ( HR=1.59, 95% CI: 1.39-1.83). Conclusion:Maternal smoking during pregnancy may increase offspring overall cancer mortality and more severe harm in individuals with high genetic risk.

Objective:To investigate the impact of air pollution on dynamic changes in lung function and further explore the association between genetic factors and lung function and its changes.Methods:Research data were from 14 506 participants in the United Kingdom Biobank with two complete baseline and follow-up lung function tests. Particulate matter [including particulate matter with aerodynamic diameter ≤2.5 μm and ≤10 μm (PM 2.5 and PM 10)], nitrogen dioxide (NO 2), and nitrogen oxides (NO x) concentrations were estimated using land-use regression models. Annual changes in lung function were calculated based on baseline and follow-up lung function tests. Polygenic risk scores (PRS) of lung function [forced expiratory volume in the first second (FEV 1), forced vital capacity (FVC), and the ratio of FEV 1 to FVC (FEV 1/FVC)] were constructed by genetic variations. The association between air pollution concentrations and lung function changes was analyzed by multiple linear regression models, and the impact of genetic factors on lung function and its changes was also assessed. Results:PM 2.5, PM 10, NO 2, and NO x showed a negative correlation with FVC changes [PM 2.5: -6.66 (95% CI: -9.92- -3.40) ml/year; PM 10: -0.40 (95% CI: -0.77- -0.03) ml/year; NO 2: -1.84 (95% CI: -2.60- -1.07) ml/year; NO x: -1.37 (95% CI: -2.27- -0.46) ml/year]. Additionally, PM 2.5, PM 10and NO 2 were also negatively correlated with changes in FEV 1 [PM 2.5: -3.19 (95% CI: -5.79- -0.59) ml/year; PM 10: -3.00 (95% CI: -5.92- -0.08) ml/year; NO 2: -0.95 (95% CI: -1.56- -0.34) ml/year]. PRS of lung function were positively correlated with baseline lung function (FVC, FEV 1, and FEV 1/FVC) and lung function changes (all β>0, all P<0.001). In different PRS stratification analyses, the effect of air pollution on lung function changes remained significant, and there was no apparent heterogeneity. Conclusions:PRS of lung function are significantly associated with baseline and lung function changes. Long-term exposure to air pollution accelerates the decline of lung function indicators such as FVC and FEV 1. The effects of air pollution are consistent in individuals with different genetic risk scores.
