Erectile dysfunction (ED) is prevalent among men, but its relationship with dietary habits is uncertain. The aim of our study was to assess whether dietary patterns enhance erectile function by reviewing the literature published before August 1, 2022, via PubMed, Web of Science, and EMBASE databases. The data compiled included author details; publication dates, countries, treatments, patient numbers, ages, follow-ups, and clinical trial outcomes, such as ED cases, odds ratios (ORs), confidence intervals (CIs), and International Index of Erectile Function-5 (IIEF-5) scores with means and standard deviations. An analysis of 14 studies with 27 389 participants revealed that plant-based diets (OR = 0.71, 95% CI: 0.66-0.75; P < 0.00001), low-fat diets (OR = 0.27, 95% CI: 0.13-0.53; P = 0.0002), and alternative diets such as intermittent fasting and organic diets (OR = 0.54, 95% CI: 0.36-0.80; P = 0.002) significantly reduced ED risk. High-protein low-fat diets (hazard ratio [HR] = 1.38, 95% CI: 1.12-1.64; P < 0.00001) and high-carb low-fat diets (HR = 0.79, 95% CI: 0.55-1.04; P < 0.00001) improved IIEF-5 scores. Combined diet and exercise interventions decreased the likelihood of ED (OR = 0.49, 95% CI: 0.28-0.85; P = 0.01) and increased the IIEF-5 score (OR = 3.40, 95% CI: 1.69-5.11; P < 0.0001). Diets abundant in fruits and vegetables (OR = 0.97, 95% CI: 0.96-0.98; P < 0.00001) and nuts (OR = 0.54, 95% CI: 0.37-0.80; P = 0.002) were also correlated with lower ED risk. Our meta-analysis underscores a strong dietary-ED association, suggesting that low-fat/Mediterranean diets rich in produce and nuts could benefit ED management.

Objective To compare the efficacy and safety between hypofractionated radiotherapy(HyRt)and conventional radiotherapy after breast-conserving surgery.Methods This study was a single-center,prospective,randomized controlled study.Eighty-three patients with pTis-T2N0M0 breast cancer admitted to Tangshan People's Hospital from May 2017 to May 2019 were included.The patients received breast-conserving surgery+sentinel lymph node biopsy(SLNB).After surgery,they were treated with intensity modulated radiation therapy(IMRT).According to random table method,patients were divided into HyRt group(n=41)and conventional radiotherapy group(n=42).The dose of organs at risk,treatment efficacy,treatment failure modes,and radiotherapy related adverse reactions were analyzed in the two groups.The radiotherapy-related adverse reactions were evaluated according to NCI CTC AE Version 3.0,including radiation dermatitis,radiation pneumonia,breast/skin fibrosis,pulmonary fibrosis,etc.Results Eighty-three patients with breast cancer were included,with a median age of 44(26-67)years.There was no statistically significant difference in clinical parameters such as age(P=0.443),TNM stage(P=0.335),molecular typing(P=0.333),degree of differentiation(P=0.617),and pathological type(P=0.127)between the two groups of patients.Compared with conventional radiotherapy group,the V5(25.6％vs.33.8％,P=0.015),V20(13.3％vs.17.2％,P=0.042),and the mean radiation dose(MLD;7.4 Gy vs.10.4 Gy,P=0.020)of the affected lung of HyRt group significantly decreased.Only 3 patients in this study experienced distant metastasis,and no regional lymph node metastasis or local recurrence was observed.There was no significant difference in PFS rate at 2 years between HyRt group and conventional radiotherapy group(94.4％vs.85.2％,P=0.818).Compared with conventional radiotherapy group,the incidence of≥grade Ⅱ irradiation dermatitis in HyRt group was significantly reduced(2.4％vs.21.4％,P=0.015).There was no difference in the incidence of grade Ⅰ breast/skin fibrosis(19.5％vs.14.3％,P=0.570)between the two groups,and no grade Ⅲ radiotherapy-related side effects were observed in the two groups.Conclusions Compared with conventional radiotherapy with simultaneously integrated boosting-intensity modulated radiotherapy,the patients who received HyRt after breast-conserving surgery for early-stage breast cancer have good tolerance and low incidence of adverse reactions.HyRt can be used as the first option of radiation therapy.

Objective To compare the fidelity of chronic obstructive pulmonary disease(COPD)models established using two methods:exposure to cigarette smoke(CS)and exposure to motor vehicle exhaust(MVE)in rats.Methods Twenty-four male SD rats were randomly divided into control,CS-exposed(CS),and MVE-exposed(MVE)groups,with 8 rats per group.Rats in CS and MVE groups were exposed to CS or MVE,respectively,to induce COPD models.After COPD model established,lung function of each group was assessed.Bronchoalveolar lavage fluid(BALF)was collected to measure inflammatory cell counts,levels of inflammatory cytokines interleukin-6(IL-6)and tumor necrosis factor(TNF)-α,and expression levels of mucin 5AC(MUC5AC).Lung tissue sections were stained with hematoxylin and eosin(HE)to observe pulmonary tissue and airway pathological changes.Periodic acid-Schiff(PAS)staining was used to detect goblet cell hyperplasia in airways.Results Compared with control group,rats in CS and MVE groups showed significantly increased inspiratory resistance(RI),total lung capacity(TLC),and lung static compliance(Cchord)(P<0.05),while expiratory flow parameters FEV50/FVC were significantly decreased(P<0.05).Compared with MVE group,rats in CS group had significantly higher RI,TLC,and Cchord(P<0.05),and lower FEV50/FVC(P<0.05).HE staining of lung tissues showed that mean linear intercept(MLI)was significantly higher in both CS and MVE groups compared with control group(P<0.05),with CS group having higher MLI than MVE group(P<0.05).BALF analysis revealed that white blood cells,neutrophils,macrophages,lymphocytes,IL-6,and TNF-α levels were significantly higher in both CS and MVE groups compared with control group(P<0.05),and inflammatory cell counts,IL-6,and TNF-α levels were higher in CS group compared with MVE group(P<0.05).PAS staining of lung tissues indicated that goblet cells in large airways were significantly increased in both CS and MVE groups compared with control group(P<0.05),with CS group showing higher goblet cell counts than MVE group(P<0.05).Expression levels of MUC5AC in BALF were significantly higher in both CS and MVE groups compared with control group(P<0.05),with CS group having significantly higher MUC5AC levels than MVE group(P<0.05).Conclusions Exposure to CS or MVE can establish a rat model of COPD,with CS exposure better mimicking characteristics of acute exacerbation of COPD compared to MVE exposure.

Background/Aims: Oral EDP-514 is a potent core protein inhibitor of hepatitis B virus (HBV) replication, which produced a >4-log viral load reduction in HBV-infected chimeric mice with human liver cells. This study evaluated the safety, pharmacokinetics, and antiviral activity of three doses of EDP-514 in treatment-naive viremic patients with HBeAgpositive or -negative chronic HBV infection. Methods: Patients with HBsAg detectable at screening and at least 6 months previously were eligible. HBeAg-positive and -negative patients had a serum/plasma HBV DNA level ≥20,000 and ≥2,000 IU/mL, respectively. Twenty-five patients were randomized to EDP-514 200 (n=6), 400 (n=6) or 800 mg (n=7) or placebo (n=6) once daily for 28 days. Results: A dose-related increase in EDP-514 exposure (AUClast and Cmax) was observed across doses. At Day 28, mean reductions in HBV DNA were –2.9, –3.3, –3.5 and –0.2 log10 IU/mL with EDP-514 200 mg, 400 mg, 800 mg, and placebo groups, respectively. The corresponding mean change from baseline for HBV RNA levels was –2.9, –2.4, –2.0, and –0.02 log10 U/mL. No virologic failures were observed. No clinically meaningful changes from baseline were observed for HBsAg, HBeAg or HBcrAg. Nine patients reported treatment emergent adverse events of mild or moderate severity with no discontinuations, serious AEs or deaths. Conclusions In treatment-naïve viremic patients, oral EDP-514 was generally safe and well-tolerated, displayed PK profile supportive of once-daily dosing, and markedly reduced HBV DNA and HBV RNA.

Fetuin-B (FETUB) is a glycoprotein mainly synthesized and secreted by the liver. It is involved in many physiological and pathological processes including glucose metabolism, inflammatory response, nonalcoholic fatty liver disease, myocardial infarction, tumor and so on. In recent years, FETUB has also been confirmed to play roles in the female reproductive system. FETUB may affect follicular development and play an important role in in vivo and in vitro fertilization. In addition, serum FETUB level is elevated significantly during pregnancy and labor. FETUB expression is changed in a variety of reproductive diseases (polycystic ovary syndrome, gestational diabetes mellitus, intrahepatic cholestasis of pregnancy). In this review, we summarize FETUB related studies in female reproduction, and focus on the roles of FETUB in female reproductive physiology and pathology, in order to provide information for the pathogenesis of reproductive disorders.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.
