Purpose:
Erectile dysfunction (ED) is a common male sexual dysfunction. Gut microbiota plays an important role in various diseases. To investigate the effects and mechanisms of intestinal flora dysregulation induced by high-fat diet (HFD) on erectile function.
Materials and Methods:
Male Sprague–Dawley rats aged 8 weeks were randomly divided into the normal diet (ND) and HFD groups. After 24 weeks, a measurement of erectile function was performed. We performed 16S rRNA sequencing of stool samples. Then, we established fecal microbiota transplantation (FMT) rat models by transplanting fecal microbiota from rats of ND group and HFD group to two new groups of rats respectively. After 24 weeks, erectile function of the rats was evaluated and 16S rRNA sequencing was performed, and serum samples were collected for the untargeted metabolomics detection.
Results:
The erectile function of rats and the species diversity of intestinal microbiota in the HFD group was significantly lower, and the characteristics of the intestinal microbiota community structure were also significantly different between the two groups. The erectile function of rats in the HFD-FMT group was significantly lower than that of rats in the ND-FMT group. The characteristics of the intestinal microbiota community structure were significantly different. In the HFD-FMT group, 27 metabolites were significantly different and they were mainly involved in the several inflammation-related pathways.
Conclusions
Intestinal microbiota disorders induced by HFD can damage the intestinal barrier of rats, change the serum metabolic profile, induce low-grade inflammation and apoptosis in the corpus cavernosum of the penis, and lead to ED.

Objective:To investigate the clinical features,gene mutation profile,efficacy and prognostic factors of primary extranodal diffuse large B-cell lymphoma(EN-DLBCL).Methods:A retrospective analysis was performed for 382 patients with primary EN-DLBCL with complete clinical data who were treated in West China Hospital from January 2013 to January 2023,and their clinical characteristics,gene mutation profile,efficacy and prognostic factors were analyzed.Results:The median age of the 382 patients with EN-DLBCL was 56 (18-89 )years old.The male-to-female ratio was 1.12∶1,and the most common primary sites were gastrointestinal tract (31.7%),Wechsler ring (19. 1%)and breast gland (7.1%).A total of 51 gene mutations were fund,and the most common frequencies of gene mutations were TP53 (32.5%),MYD88 (32.5%),and CD79B (30.0%).The median follow-up was 63 months,and the 5-year progression-free survival (PFS)rate was 74.5% and the 5-year overall survival (OS)rate was 89.6%. The adverse factors on PFS were as follows:>1 extranodal sites involvement (P<0.001),P53≥50%(P<0.001),hyper double expression(hDEL)of C-myc>50%/Bcl-2>70%(P<0.001).The adverse factors affecting the OS of patients were as follows:>1 extranodal sites involvement (P<0.001),P53≥50%(P<0.001),hDEL(P<0.001). Chemotherapy combined with local radiotherapy could improve PFS (P=0.041)and OS (P=0.003),while R-CHOP+X (molecule agents as BTKi、HDACi、Lenalidomide)failed to show a significant difference in PFS (P=0.075)and OS (P=0.767 ).Among the 40 patients who underwent next-generation sequencing at high risk,there was no significant in PFS (P=0.849)and OS (P=0.500)of patients with positive MYD88 and/or CD79B mutations (MCD subtype)treated with BTKi and patients with negative MYD88 and CD79B mutations.Conclusion:Primary EN-DLBCL can involve multiple organs or tissue sites.TP53,MYD88,and CD79B are the most common gene mutations.The efficacy of BTKi in patients with positive MCD subtypes at intermediate and high risk is not inferior to that in MCD-negative control patients.

Objective:To explore the correlation between the initial estimated glomerular filtration rate (eGFR) and all-cause mortality in end-stage renal disease (ESRD) patients undergoing urgent-start peritoneal dialysis (USPD).Methods:The clinical data of 380 ESRD patients undergoing USPD from January 2013 to June 2023 in Affiliated Hospital of Jining Medical University were retrospective analyzed. According to the median initial eGFR of 6.25 ml/(min·1.73 m 2), the patients were divided into low eGFR group with eGFR<6.25 ml/(min·1.73 m 2) and high eGFR group with eGFR ≥6.25 ml/(min·1.73 m 2), with 190 patients in each group. The baseline characteristics and hematological indexes within 48 h before USPD were compared between the two groups. The patients were followed up until death or until June 30, 2023, and all-cause mortality was recorded. The Kaplan-Meier survival curve was used to evaluate the accumulated survival rate. Multivariate Cox regression analyses were used to identify the independent risk factors for all-cause mortality in ESRD patients undergoing USPD, with subgroup analyses based on age, gender and diabetes. Results:The median follow-up time was 40.7 (21.7, 59.0) months, 112 patients died, with a total mortality rate of 29.5% (112/380). The blood potassium, blood phosphorus, urea nitrogen, uric acid, parathyroid hormone and dialysis age in high eGFR group were significantly lower than those in low eGFR group: (4.1 ± 0.7) mmol/L vs. (4.5 ± 0.8) mmol/L, (1.6 ± 0.4) mmol/L vs. (1.9 ± 0.6) mmol/L, (21.8 ± 7.2) mmol/L vs. (29.7 ± 11.0) mmol/L, (359.8 ± 99.4) μmol/L vs. (429.4 ± 116.9) μmol/L, 242.2 (151.5, 398.3) ng/L vs. 281.7 (189.1, 487.2) ng/L and 36.1 (18.8, 54.0) months vs. 43.7 (28.8, 68.2) months, the diabetes rate, hemoglobin, platelet count, blood chloride, fasting blood glucose and mortality rate were significantly higher than those in low eGFR group: 20.0% (38/190) vs. 11.6% (22/190), (100.6 ± 18.2) g/L vs. (96.1 ± 20.0) g/L, (207.7 ± 72.6) × 10 9/L vs. (192.4 ± 65.6) × 10 9/L, (100.6 ± 4.1) mmol/L vs. (99.4 ± 4.7) mmol/L, (5.9 ± 2.3) mmol/L vs. (5.5 ± 1.9) mmol/L and 34.2% (65/190) vs. 24.7% (47/190), and there were statistical differences ( P<0.01 or< 0.05). Kaplan-Meier survival curve analysis result showed that the all-cause mortality rate in high eGFR group was significantly higher than that in low eGFR group, and there was statistical difference (log-rank χ2 = 6.64, P<0.01). After adjusting for gender, age and confounding factors, multivariate Cox regression analysis result showed that elevated eGFR, increased mean corpuscular volume and elevated fasting blood glucose were independent risk factors for all-cause mortality in ESRD patients undergoing USPD ( HR = 1.14, 1.04 and 1.15; 95% CI 1.04 to 1.26, 1.01 to 1.08 and 1.03 to 1.29; P<0.01 or<0.05), while female was an independent protective factor ( HR = 0.59, 95% CI 0.38 to 0.92, P<0.05). Subgroup analysis result showed a consistent effect of eGFR on mortality in ESRD patients undergoing USPD. Conclusions:Higher initial eGFR in ESRD patients undergoing USPD is associated with an increased risk of all-cause mortality.

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the safety profile of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects that previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extending or switching TMF treatment for 48 weeks. Safety profiles of kidney, bone, metabolism, body weight, and others were evaluated.Results:666 subjects from the initial TMF group and 336 subjects from TDF group with at least one dose of assigned treatment were included at week 144. The overall safety profile was favorable in each group and generally similar between extended or switched TMF treatments from week 96 to 144. In subjects switching from TDF to TMF, the non-indexed estimated glomerular filtration rate (by non-indexed CKD-EPI formula) and creatinine clearance (by Cockcroft-Gault formula) were both increased, which were (2.31±8.33) ml/min and (4.24±13.94) ml/min, respectively. These changes were also higher than those in subjects with extending TMF treatment [(0.91±8.06) ml/min and (1.30±13.94) ml/min]. Meanwhile, switching to TMF also led to an increase of the bone mineral density (BMD) by 0.75% in hip and 1.41% in spine. On the other side, a slight change in TC/HDL ratio by 0.16 (IQR: 0.00, 0.43) and an increase in body mass index (BMI) by (0.54±0.98) kg/m 2 were oberved with patients switched to TMF, which were significantly higher than that in TMF group. Conclusion:CHB patients receiving 144 weeks of TMF treatment showed favorable safety profile. After switching to TMF, the bone and renal safety was significantly improved in TDF group, though experienceing change in metabolic parameters and weight gain (NCT03903796).
