We tested the association between endogenous testosterone density(ETD;the ratio between endogenous testosterone[ET]and prostate volume)and prostate cancer(PCa)aggressiveness in very favorable low-and intermediate-risk PCa patients who underwent radical prostatectomy(RP).Only patients with prostate-specific antigen(PSA)within 10 ng ml^(-1),clinical stage T1c,and International Society of Urological Pathology(IsUP)grade group 1 or 2 were *** ET levels up to 350 ng dl^(-1)were classified as *** quantitation density factors were evaluated as the ratio between percentage of biopsy-positive cores and prostate volume(biopsy-positive cores density,BPCD)and the ratio between percentage of cancer invasion at final pathology and prostate weight(tumor load density,TLD).Disease upgrading was coded as ISUP grade group>2,and progression as recurrence(biochemical and/or local and/or distant).Risk associations were evaluated by multivariable Cox and logistic regression *** 320 patients,151(47.2%)had intermediate-risk ***(median:402.3 ng dl^(-1))resulted abnormal in 111(34.7%)cases(median ETD:9.8 ng dl^(-1)ml^(-1)).Upgrading and progression occurred in 109(34.1%)and 32(10.6%)cases,*** was predicted by ISUP grade group 2(hazard ratio[HR]:2.290;P=0.029)and upgrading(HR:3.098;P=0.003),which was associated with ISUP grade group 2(odds ratio[OR]:1.785;P=0.017)and TLD above the median(OR:2.261;P=0.001).After adjustment for PSAdensity and bodymass index(BMI),ETDabovethemedianwas positivelyassociatedwithBPCD(OR:3.404;P<0.001)and TLD(OR:5.238;P<0.001).Notably,subjects with abnormal ET were more likely to have higher BPCD(OR:5.566;P=0.002),as well as TLD(OR:14.998;P=0.016).Independently by routinely evaluated factors,as ETD increased,BPCD and TLD increased,but increments were higher for abnormal ET *** very favorable cohorts,ETD may further stratify the risk of aggressive PCa.

Intranasal nerve growth factor bypasses the blood-brain barrier and affects spinal cord neurons in spinal cord injury

引用

Neural Regeneration Research 2014年第10期9卷 1025-1030页

作者： Luigi Aloe Patrizia bianchi Alberto De Bellis Marzia Soligo Maria Luisa Rocco Cellular Biology and Neurobiology Institute National Research Council(CNR) Maria Rosaria Maglione Foundation Onlus NapoliItaly Intitute of Translational Pharmacology National Research Council(CNR)

The purpose of this work was to investigate whether, by intranasal administration, the nerve growth factor bypasses the blood-brain barrier and turns over the spinal cord neurons and if such therapeutic approach could be of value in the treatment of spinal cord injury. Adult Sprague-Dawley rats with intact and injured spinal cord received daily intranasal nerve growth factor administration in both nostrils for 1 day or for 3 consecutive weeks. We found an in-creased content of nerve growth factor and enhanced expression of nerve growth factor receptor in the spinal cord 24 hours after a single intranasal administration of nerve growth factor in healthy rats, while daily treatment for 3 weeks in a model of spinal cord injury improved the deifcits in locomotor behaviour and increased spinal content of both nerve growth factor and nerve growth factor receptors. These outcomes suggest that the intranasal nerve growth factor bypasses blood-brain barrier and affects spinal cord neurons in spinal cord injury. They also suggest exploiting the possible therapeutic role of intranasally delivered nerve growth factor for the neuroprotection of damaged spinal nerve cells.

The use of choline in association with the Bangerter filters for the treatment of amblyopia

引用

International Journal of Ophthalmology(English edition) 2017年第11期10卷 1777-1778页

作者： Lelio Sabetti Francesco Masedu Chiara Tresca Federica bianchi Marco Valenti Department of Biotechnological and Applied Clinical Sciences University of L'Aquila L'Aquila 67100 Italy

The study investigated the effects of choline combined with Bangerter filter in the treatment of amblyopia. All amblyopic subjects used a Bangerter filter on the corrective spectacle lens（1 d over the left eye, 1 d over the right eye）. Choline was then administered orally to 39 patients once daily, five days per week for the entire study period. Subjects treated with the Bangerter filter showed a mean visual acuity of 0.27 logM AR; at 12 mo of treatment, the mean visual acuity reached 0.09 log MAR. Patients treated with the Bangerter filter and citicoline showed a mean visual acuity of 0.35 log MAR; at 12 mo of treatment, the mean visual acuity reached 0.01 logMAR. No significant changes in the angle of deviation were observed in both groups. Subjects in both forms of amblyopia therapies demonstrated an increase in visual acuity. However, these effects were markedly enhanced when coupled with the administration of choline. Findings suggest that the effects are particularly relevant in the more severe amblyopic cases.

Pre-illness changes in dietary habits and diet as a risk factor for inflammatory bowel disease: A case-control study

引用

World Journal of Gastroenterology 2010年第34期16卷 4297-4304页

作者： Giovanni Maconi Sandro Ardizzone Claudia Cucino Cristina Bezzio Antonio Giampiero Russo Gabriele bianchi Porro Department of Clinical Sciences L. Sacco University Hospital Endoscopy Unit Istituto Clinico Santa Rita 20131 Milan Italy Epidemiology and Biostatistics Unit San Carlo Borromeo Hospital

AIM: To evaluate whether symptoms of inflammatory bowel disease (IBD), before diagnosis modify dietary habits, and to investigate the pre-illness diet in patients with recent IBD in comparison with an age-matched healthy control group. METHODS: Overall, 83 new cases of IBD (41 ulcerative colitis, 42 Crohn's disease) and 160 healthy controls were studied. Portions per week of 34 foods and beverages before onset of symptoms were recorded using a validated questionnaire. Duration of symptoms before IBD diagnosis, presence of specific symptoms and their impact on subjective changes in usual dietary habits were also recorded. The association between diet and IBD was investigated by multiple logistic regression and dietary patterns were assessed by factor analysis. RESULTS: Changes in dietary habits, due to the presence of symptoms, were reported by 38.6% of patients and were not significantly related to specific symptoms, rather to long duration of symptoms, only in Crohn's disease patients. In IBD patients who did not change dietary habits, moderate and high consumption of margarine (OR = 11.8 and OR = 21.37) was associated with ulcerative colitis, whilst high consumption of red meat (OR = 7.8) and high intake of cheese were associated with Crohn's disease. CONCLUSION: More than one third of IBD patients change dietary habits before diagnosis. Margarine, red meat and cheese increase the risk of ulcerative colitis and Crohn's disease.
