Background: The prevalence of prostate cancer (PCa) has been increasing in recent years. Treatment strategies are largely based on the results of bone scan screening. Therefore, our aim was to investigate predictors of positive bone metastasis in newly diagnosed PCa patients. Materials and Methods: After extensive review, 336 consecutive patients newly diagnosed with PCa between April 2010 and November 2013 at our institution were enlisted in the study. Patients were divided into two groups according to bone scan results. Univariate analyses (Chi-square test for discrete variables and independent t-test for continuous variables) were applied to determine the potentially significant risk factors associated with distant bone metastasis. Binary logistic regression analyses were used to further investigate the influence of these factors on bone metastasis. Results: The patient mean age was $71.9{\pm}8.6years$ (range: 48 to 94 years). The mean prostate specific antigen (PSA) level and biopsy Gleason score were $260.2{\pm}1107.8ng/mL$ and $7.4{\pm}1.5$, respectively. The body mass index (BMI) for the series was $24.5{\pm}3.4kg/m^2$. Sixty-four patients (19.0%) had a positive bone scan result. Patients with positive bone scan results had a significantly lower BMI ($23.3{\pm}3.5$ vs. $24.8{\pm}3.3$; p=0.003), a higher Gleason score ($8.5{\pm}1.1$ vs. $7.1{\pm}1.5$; p < 0.001), and a higher PSA level ($1071.3{\pm}2337.1$ vs. $69.4{\pm}235.5$; p < 0.001) than those without bone metastasis. Multivariate logistic regression analysis employing the above independent predictors demonstrated that a Gleason score of ${\geq}7$, clinical stage ${\geq}T3$, $BMI{\leq}22kg/m^2$, and an initial PSA level of ${\geq}20ng/mL$ were all independent predictors of bone metastasis. Conclusions: A bone scan might be necessary in newly diagnosed PCa patients with any of the following criteria: clinical stage T3 or higher, a Gleason score of 7 or higher, BMI equal to or less than 22, and a PSA level of 20 or higher.

Purpose: Some evidence suggests that male infertility increases the risk of cardiovascular diseases (CVDs). However, the evidence in Asian populations is relatively scarce. The aim of this study is to determine whether male infertility increases the risk of CVDs. Materials and Methods: We used inpatient and outpatient data for the years 2000 to 2015 from the Taiwanese Longitudinal Health Insurance Database. We enrolled 7,016 males over 18 years old and diagnosed with male infertility. Of these, 2,326 matched our inclusion criteria and were assigned to the study group. For each infertility patient, four comparison patients were frequency-matched by age and index date to form a control cohort comprising 9,304 patients. Cox proportional hazards analysis was used to estimate the association between male infertility and CVDs. Results: After a 15-year follow-up, the incidence rate of CVDs was higher in the infertility group than the control group (1,460.23 and 1,073.70 per 100,000 person-years, respectively). The Cox proportional hazards regression analysis revealed that the adjusted HR for CVDs was 1.472 for the infertility group (95% CI, 1.288–1.683; p<0.001) relative to the control group. The Kaplan–Meier analysis of the cumulative incidence of CVDs in the two groups showed that the cumulative risk curve for CVDs was significantly higher for the infertility group than the control group. Conclusions: This study shows that men with infertility have a higher risk of developing incident CVDs. In the future, healthcare providers should pay attention to these patients because of their higher health risks.

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eightytwo colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P = 0.011). The patients with IL10rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P = 0.007) and in multivariate Cox regression model (P = 0.044) adjusting for age, gender,carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion,and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.

혼합 코풀라 모형은 대만 주식시장에서 외국계 기관투자가, 뮤추얼펀드 및 딜러의 극단수익률과 주식거래회전율 간의 관계를 연구하기 위해 사용되었다. 본 연구에서 는 극단적인 투자손실이 발생한 상황에서의 거래증가량을 연구하기 위한 변환된 함 수가 기재되었다. 실증결과 딜러는 극심한 손실 혹은 극심한 이익이 발생한 기간 모 두에서 가장 높은 거래량 증가를 나타내고 있다. 외국계 기관투자가와 비교했을 때, 뮤추얼펀드는 이익이 극대화되는 기간에 높은 거래량 증가 상태를 보였다. 이와 반 대로 뮤추얼펀드 비교했을 때 외국계 기관투자가는 극심한 투자손실이 발생되는 경 우에 높은 거래량 증가를 보였다. 극심한 주식수익률은 거래증가량에 비대칭적인 영 향을 끼치는 것을 확인할 수 있었다. Mixture copula models are used to study the relationships of extreme return and stock turnover rates of the foreign institutional investors, mutual funds and dealers in Taiwan. A transformation function is introduced in this paper to study the trading volume increment during extreme negative return condition. The results show that dealer has the highest trading volume increases both during extreme positive return and negative return periods. Comparing with foreign institutional investor, mutual fund has the higher trading increase during extreme positive return period. Comparing with mutual fund, foreign institutional investor has higher trading increase during extreme negative return period. The extreme stock market return has asymmetric impacts on the trading volume increment.

Background Melanogenesis is a complex process which is tightly regulated by several enzymes. However, abnormal melanogenesis can cause severe dermatological problems. Roots of Angelica dahurica have been used for skin care as a part of traditional Chinese medicine for many generations. However, the role of A. dahurica in melanogenesis remains unclear. Objective Previous in vitro and in vivo studies have demonstrated that NK-1R exerts positive effects in melanogenesis via the Wnt/βcatenin signaling pathway. In this study, we investigated the effects of A. dahurica ethanol extract (ADE) on NK-1R and Wnt/β-catenin signaling, and evaluated the effect of NK-1R on melanogenesis in B16F0 cells. Results Angelica dahurica ethanol extract efficiently downregulated Neurokinin-1 receptor and Wnt/β-catenin signaling by decreasing the expression of β-catenin, MITF, LEF-1, TYR, TRP1, and TRP2 and increasing the expression of GSK3β, which resulted from the weakened expression of the Neurokinin-1 receptor inhibitor [Sar9,Met(O2 )11]-Substance P (SMSP). Furthermore, the intracellular melanin assay and cellular tyrosinase activity confirmed these findings. Conclusion This study suggests that ADE has potential to downregulate Neurokinin-1 receptor in SMSP-induced B16F0 cells, thereby repressing the Wnt/β-catenin signaling and reduces melanin production.
