RESUMO
Breast cancer (BC) patients in China suffered from a variety of psychology stress such as perceived stress and anxiety, posttraumatic growth (PTG) as a positive factor could promote their psychology health and quality of life. This study aimed to investigate the efficacy of mindfulness-based stress reduction (MBSR) on promoting PTG, decreasing perceived stress and anxiety of Chinese BC patients. A randomized controlled trial of 60 BC patients (Stages I-III) was conducted. They were randomly divided to the 8-week MBSR group or usual care (UC) group. PTG inventory, Perceived Stress Scale of Chinese version (CPSS) and State Trait Anxiety Inventory (STAI) evaluated the PTG level, perceived stress and anxiety at three times(before intervention-T1, after intervention-T2 and follow up at 3 months-T3). A repeated-measures analysis of variance model was used to compare each outcome measure of two groups at the three times. There was one patient discontinued the intervention and one lose to follow up in MBSR group, finally 58 BC patients completed the research. There was no difference between two groups before the intervention. The results showed significant improvements in MBSR group comparing with the UC group that PTG level was much higher after the 8-week intervention and the follow up (F = 34.73, p < .00). At the same time, CPSS (F = 14.41, p < .00) and STAI (F = 15.24, p < .00) scores were significant decreased at T2 and T3. The results showed that MBSR promoted the level of PTG and decreased perceived stress and anxiety state of Chinese BC patients, and the results persisted at three months after intervention. The research preliminary proved that MBSR was suitable to Chinese BC patients. MBSR should be recommending to BC survivors in China.

Penicitroamide (1), a new metabolite with a new framework, was isolated from the ethyl acetate extract of the PDB (Potato Dextrose Broth) medium of Penicillium sp. (NO. 24). The endophytic fungus Penicillium sp. (NO. 24) was obtained from the healthy leaves of Tapiscia sinensis Oliv. The structure of penicitroamide (1) features a bicyclo[3.2.1]octane core unit with a high degree of carbonylization (four carbonyl groups and one enol group). The chemical structure of penicitroamide (1) was elucidated by analysis of 1D-, 2D-NMR and MS data. In bioassays, penicitroamide (1) displayed antibacterial potency against two plant pathogens, Erwinia carotovora subsp. Carotovora (Jones) Bersey, et al. and Sclerotium rolfsii Sacc. with MIC50 at 45 and 50 µg/mL. Compound 1 also showed 60% lethality against brine shrimp at 10 µg/mL. Penicitroamide (1) exhibited no significant activity against A549, Caski, HepG2 and MCF-7 cells with IC50 > 50 µg/mL. Finally, the possible biosynthetic pathway of penicitroamide (1) was discussed.

OBJECTIVE: To evaluate the impacts of three different surgical approaches to urethral stricture on the erectile function of the patients. METHODS: This study included 126 male patients with urethral stricture, 35 treated by substitution urethroplasty (group A), 52 by anastomotic urethroplasty (group B), and 39 by internal urethroplasty (group C). We evaluated the pre- and postoperative erectile function of the patients using IIEF-5 scores by telephone calls and interviews. We also monitored their nocturnal penile tumescence (NPT). RESULTS: The IIEF-5 scores in groups A, B and C were 13.5 +/- 4.5, 11.1 +/- 4.8 and 14.5 +/- 4.41 respectively after surgery, all significantly decreased as compared with 17.1 +/- 2.6, 17.1 +/- 3.0 and 17.6 +/- 2.2 preoperatively (P < 0.05). CONCLUSION: All the three surgical approaches can reduce IIEF-5 scores in patients with urethral stricture, but anastomotic urethroplasty may induce a higher incidence of erectile dysfunction than the other two approaches.

PURPOSE: The prognostic efficiency of clinical grading and staging in patients with confined or moderately differentiated prostate cancer (PCa) has been markedly improved, which underscores the importance of new prognostic markers. Extracellular matrix metalloproteinase inducer (EMMPRIN) has been demonstrated to be involved in cancerangiogenesis, metastasis and invasion. EMMPRIN expression was evaluated by measuring mRNA and protein levels in a large cohort of patients with PCa following prostatectomy and the findings were compared with clinico-pathological parameters, including prostate-specific antigen (PSA) relapse time. METHODS: EMMPRIN mRNA levels in 20 pairs of normal and cancerous prostate tissues were determined by quantitative real-time PCR. Protein expression in paraffin-embedded specimens of prostates gathered from 300 patients with PCa was detected by immunohistochemistry using a monoclonal antibody against EMMPRIN. The associations of EMMPRIN protein expression with the clinico-pathological parameters and PSA relapse-free time after radical prostatectomy were subsequently assessed. RESULTS: Both EMMPRIN mRNA and protein levels were higher in PCa tissue, compared with adjacent normal tissue. In addition, the positive expression rates of EMMPRIN in PCa tissues were significantly associated with preoperative PSA levels (p=0.008), AJCC stage (p=0.006) and Gleason Score (p < 0.001), Risk classification (p < 0.001), lymph node status post-surgery (p < 0.001) and surgical margin status (p < 0.001) were also determined. Multivariate analysis, using the Cox proportional hazards model, revealed that positive EMMPRIN expression was an independent prognostic factor for an increased risk of PSA relapse. CONCLUSION: Over-expression of EMMPRIN correlated with the aggressiveness of PCa, and the PSA relapse-free time, and may be a novel and useful biomarker for follow-up and treatment decisions for PCa.
