Abstract
Castration-resistant prostate cancer (CRPC) cells can resist many cellular stresses to ensure survival. There is an unmet medical need to fight against the multiple adaptive mechanisms in cells to achieve optimal treatment in patients. Para-toluenesulfonamide (PTS) is a small molecule that inhibited cell proliferation of PC-3 and DU-145, two CRPC cell lines, through p21- and p27-independent G1 arrest of cell cycle in which cyclin D1 was down-regulated and Rb phosphorylation was inhibited. PTS also induced a significant loss of mitochondrial membrane potential that was attributed to up-regulation of both Bak and PUMA, two pro-apoptotic Bcl-2 family members, leading to apoptosis. PTS inhibited the phosphorylation of m-TOR, 4E-BP1, and p70S6K in both cell lines. Overexpression of constitutively active Akt rescued the inhibition of mTOR/p70S6K signaling in PC-3 cells indicating an Akt-dependent pathway. In contrast, Akt-independent effect was observed in DU-145 cells. Lipid rafts serve as functional platforms for multiple cellular signaling and trafficking processes. Both cell lines expressed raft-associated Akt, mTOR, and p70S6K. PTS induced decreases of expressions in both raft-associated total and phosphorylated forms of these kinases. PTS-induced inhibitory effects were rescued by supplement of cholesterol, an essential constituent in lipid raft, indicating a key role of cholesterol contents. Moreover, the tumor xenograft model showed that PTS inhibited tumor growth with a T/C (treatment/control) of 0.44 and a 56% inhibition of growth rate indicating the in vivo efficacy. In conclusion, the data suggest that PTS is an effective anti-tumor agent with in vitro and in vivo efficacies through inhibition of both Akt-dependent and -independent mTOR/p70S6K pathways. Moreover, disturbance of lipid raft and cholesterol contents may at least partly explain PTS-mediated anti-tumor mechanism.

Abstract
Parkinson’s disease (PD) is the second most common degenerative disorder of the central nervous system in the elderly. It is characterized by progressive loss of dopaminergic neurons in the substantia nigra pars compacta, as well as by motor dysfunction. Although the causes of PD are not well understood, aggregation of α-synuclein (α-syn) in neurons contributes to this disease. Current therapeutics for PD provides satisfactory symptom relief but not a cure. Treatment strategies include attempts to identify new drugs that will prevent or arrest the progressive course of PD by correcting disease-specific pathogenic process. Betulin is derived from the bark of birch trees and possesses anticancer, antimicrobial, and anti-inflammatory properties. The aim of the present study was to evaluate the potential for betulin to ameliorate PD features in Caenorhabditis elegans (C. elegans) models. We demonstrated that betulin diminished α-syn accumulation in the transgenic C. elegans model. Betulin also reduced 6-hydroxydopamine-induced dopaminergic neuron degeneration, reduced food-sensing behavioral abnormalities, and reversed life-span decreases in a pharmacological C. elegans model. Moreover, we found that the enhancement of proteasomes activity by promoting rpn1 expression and downregulation of the apoptosis pathway gene, egl-1, may be the molecular mechanism for betulin-mediated protection against PD pathology. Together, these findings support betulin as a possible treatment for PD and encourage further investigations of betulin as an antineurodegenerative agent.

Abstract
Diabetic retinopathy (DR) is a severe and recurrent microvascular complication in diabetes. The multifunctional response gene to complement 32 (RGC-32) is involved in the regulation of cell cycle, proliferation, and apoptosis. To investigate the role of RGC-32 in the development of DR, we used human retinal microvascular endothelial cells under high-glucose conditions and type 2 diabetes (T2D) mice (+Leprdb/ + Leprdb, db/db). The results showed that RGC-32 expression increased moderately in human retinal endothelial cells under hyperglycemic conditions. Histopathology and RGC-32 expression showed no significant changes between T2D and control mice retina at 16 and 24 weeks of age. However, RGC-32 expression was significantly decreased in T2D mouse retina compared to the control group at 32 weeks of age, which develop features of the early clinical stages of DR, namely reduced retinal thickness and increased ganglion cell death. Moreover, immunohistochemistry showed that RGC-32 was predominantly expressed in the photoreceptor inner segments of control mice, while the expression was dramatically lowered in the T2D retinas. Furthermore, we found that the level of anti-apoptotic protein Bcl-2 was decreased (approximately 2-fold) with a concomitant increase in cleaved caspase-3 (approximately 3-fold) in T2D retina compared to control. In summary, RGC-32 may lose its expression in T2D retina with features of DR, suggesting that it plays a critical role in DR pathogenesis.

Abstract
The benefit of androgen-deprivation therapy (ADT) in combination with dose-escalated radiotherapy (DERT) for localized prostate cancer has not been determined in randomized studies. In this study, the benefit of ADT was assessed in patients uniformly treated with dose-escalated intensity-modulated radiation therapy (IMRT) to the prostate and seminal vesicles but not pelvis. In all, 419 patients with localized prostate adenocarcinoma underwent definitive IMRT (cumulative dose 78 Gy), with 32.6%, 33.1%, 32.1%, and 2.1% having T1 through T4 disease, respectively, and 51.2% having high-risk disease. ADT was given to 76.1% of patients. With a median follow-up of 60 months, 5-year biochemical failure-free, disease-free, and overall survival rates were 87%, 86%, and 87%, respectively. T stage was an independent predictor of all three rates. Five-year pelvic nodal recurrence rate was 2.9%. ADT improved biochemical failure-free and disease-free survival but not overall survival. ADT showed benefit in high-risk disease but not intermediate-risk disease. Late gastrointestinal and genitourinary toxicities ≥ grade 2 occurred in 11.0% and 6.7%, respectively. In conclusion, DERT with 78 Gy yields good disease control and low rate of pelvic nodal recurrence. ADT improves disease-free survival in patients with high-risk but not intermediate-risk disease.

Abstract
Diabetic retinopathy (DR) is a common microvascular complication of diabetes. Circulating endothelial progenitor cells (EPCs) are derived from bone marrow and are characterized by pathological retinal neovascularization. Rho GTPase Activating Protein 22 (ARHGAP22) is a DR susceptibility gene that interacts with its downstream regulatory protein ras-related C3 botulinum toxin substrate 1 (Rac1), to assist in endothelial cell angiogenesis and increasing capillary permeability. The aim of this study was to elucidate the relationship between ARHGAP22 expression and EPC levels in type 2 diabetes (T2D) patients with DR. Fifty T2D patients with DR were recruited. Circulating EPCs were characterized as CD31+/vascular endothelial growth factor-2+/CD45dim/CD133+ and were quantified using triple staining flow cytometry. Real-time polymerase chain reaction tests were used to quantify ARHGAP22 expression. We found that T2D patients with proliferative DR had significantly lower EPC levels than those with non-proliferative DR (P = 0.028). T2D patients with EPC levels above the median value (> 4 cells/105 events) had higher levels of ARHGAP22 expression (P = 0.002). EPC levels were positively correlated with ARHGAP22 expression (r = 0.364, P = 0.009). Among T2D patients with DR, a higher expression of ARHGAP22 was associated with higher levels of EPCs. ARHGAP22 may be involved in the mobilization or active circulation of EPCs, thus contributing to neovascularization during DR development.

Abstract
BACKGROUND/AIM Mounting evidence has suggested that polymorphisms in the promoters of matrix metalloproteinase (MMP) genes are associated with the risk of many types of cancer, but no study has ever explored these polymorphisms as biomarkers for renal cell cancer (RCC). Recently, it was suggested that serum MMP-7 levels have both diagnostic and prognostic potential for RCC. In this study, we focused on the contribution of two functional polymorphisms in the promoter region of MMP-7 (A-181G and C-153T) to RCC. MATERIALS AND METHODS These two polymorphisms were genotyped in 92 patients with RCC and 580 controls by PRC-RFLP analysis. RESULTS The results showed that there is no significant association of the RCC risk with the MMP-7 A-181G genotype, even after adjusted for the possible confounding factors. The MMP-7 C-153T polymorphism was not identified among the subjects investigated. CONCLUSION Our findings suggest that the two MMP-7 polymorphisms A-181G and C-153T do not play a major role in determining personal susceptibility to RCC in Taiwan.

Abstract
Objective Lower urinary tract symptoms (LUTS) in males can reduce patients’ quality of life (QoL) and affect sexual function and satisfaction. Although this has been documented in the US, Canada, Germany, Italy, UK, and Sweden, data are limited on the effects of LUTS on QoL and sexual function in Asian men. The present subgroup analysis of an Internet‐based survey correlated the incidence of male LUTS by severity and category with self‐assessed QoL and sexual function and satisfaction measures. Methods Males aged ≥40 years were randomly selected from consumer survey panels in China, Taiwan, and South Korea. LUTS were defined using the International Continence Society (ICS) 2002 symptom definitions; symptom severity was assessed by the International Prostate Symptom Score (IPSS). The effect of LUTS on QoL was assessed using Patient Perception of Bladder Condition (PPBC) and IPSS QoL scores. Sexual function and satisfaction were assessed using the International Index of Erectile Function (IIEF). Results Men with moderate‐to‐severe LUTS and overlap of voiding, storage, and post‐micturition symptom categories reported dissatisfaction with their QoL and sexual function. LUTS severity was negatively correlated with IIEF scores. Overlap of LUTS categories had a greater effect on QoL and sexual satisfaction than the incidence of just 1 LUTS. Conclusion The findings of the present study suggest that LUTS is prevalent in >60% of Asian males aged ≥40 years and is associated with reduced QoL and sexual function, particularly in those with overlap of LUTS categories and greater symptom severity.

Hemorrhagic or ischemic stroke reportedly induces the disruption of the BBB. However, few studies have reported a correlation between the incidence of meningitis in patients with a history of stroke. This study tested the hypothesis that patients with a history of stroke may be more vulnerable to meningitis. Methods Stroke and age-matched comparison (n = 29,436 and 87,951, respectively) cohorts were recruited from the Taiwan National Health Insurance database (2000–2011). Correlations between the two cohorts were evaluated by Cox proportional hazard regression model, Kaplan–Meier curve, and log-rank tests. Results The incidence of meningitis was higher in the stroke cohort compared to that in the comparison cohort [hazard ratio (HR), 2.89; 95% confidence interval (CI), 2.23–3.74, p < 0.001]. After adjusting for age, sex, and comorbidities, the estimated HR in the stroke cohort was 2.55-fold higher than that in the comparison cohort (CI, 1.94–3.37; p < 0.001). Notably, patients who had experienced hemorrhagic stroke had a higher incidence rate of meningitis than those with a history of ischemic stroke, except for patients older than 75 years (incidence rates in hemorrhagic/ischemic stroke patients, 3.14/1.48 in patients younger than 45 years, 1.52/0.41 in 45- to 64-year group, 1.15/0.90 in 65- to 74-year group, 0.74/0.93 in patients older than 75 years). Moreover, stroke patients who had undergone head surgery had the highest meningitis risk (adjusted HR, 8.66; 95% CI, 5.55–13.5; p < 0.001) followed by stroke patients who had not undergone head surgery (adjusted HR, 2.11; 95% CI, 1.57–2.82; p < 0.001). Conclusion Our results indicated that stroke patients have higher risks of meningitis. Compromised BBB integrity in stroke patients may lead to increased vulnerability to infectious pathogens. In summary, our study provided new evidence of the clinical relationship between stroke and meningitis, and our findings suggest the need for precautions to prevent meningitis in stroke patients.

Abstract
Parkinson's disease (PD) causes motor dysfunction and dopaminergic cell death. Drug treatments can effectively reduce symptoms but often cause unwanted side effects. Stem cell therapies using cell replacement or indirect beneficial secretomes have recently emerged as potential therapeutic strategies. Although various types of stem cells have been proposed as possible candidates, adipose-derived stem cells (ADSCs) are easily obtainable, more abundant, less ethically disputed, and able to differentiate into multiple cell lineages. However, treatment of PD using adult stem cells is known to be less efficacious than neuron or embryonic stem cell transplantation. Therefore, improved therapies are urgently needed. n-Butylidenephthalide (BP), which is extracted from Angelica sinensis, has been shown to have anti-inflammatory and neuroprotective effects. Indeed, we previously demonstrated that BP treatment of ADSCs enhances the expression of neurogenesis and homing factors such as nuclear receptor related 1 protein, stromal-derived factor 1, and brain-derived neurotrophic factor. In the present study, we examined the ability of BP-pretreated ADSC transplantation to improve PD motor symptoms and protect dopamine neurons in a mouse model of PD. We evaluated the results using neuronal behavior tests such as beam walking, rotarod, and locomotor activity tests. ADSCs with or without BP pretreatment were transplanted into the striatum. Our findings demonstrated that ADSC transplantation improved motor abilities with varied efficacies and that BP stimulation improved the therapeutic effects of transplantation. Dopaminergic cell numbers returned to normal in ADSC-transplanted mice after 22 d. In summary, stimulating ADSCs with BP improved PD recovery efficiency. Thus, our results provide important new strategies to improve stem cell therapies for neurodegenerative diseases in future studies.

Abstract
A series of triazole-based small molecules that mimic FTY720-mediated anticancer activity but minimize its immunosuppressive effect have been produced. SPS-7 is the most effective derivative displaying higher activity than FTY720 in anti-proliferation against human hormone-refractory prostate cancer (HRPC). It induced G1 arrest of cell cycle and subsequent apoptosis in thymidine block-mediated synchronization model. The data were supported by a decrease of cyclin D1 expression, a dramatic increase of p21 expression and an associated decrease in RB phosphorylation. c-Myc overexpression replenished protein levels of cyclin D1 indicating that c-Myc was responsible for cell cycle regulation. PI3K/Akt/mTOR signaling pathways through p70S6K- and 4EBP1-mediated translational regulation are critical to cell proliferation and survival. SPS-7 significantly inhibited this translational pathway. Overexpression of Myr-Akt (constitutively active Akt) completely abolished SPS-7-induced inhibitory effect on mTOR/p70S6K/4EBP1 signaling and c-Myc protein expression, suggesting that PI3K/Akt serves as a key upstream regulator. SPS-7 also demonstrated substantial anti-tumor efficacy in an in vivo xenograft study using PC-3 mouse model. Notably, FTY720 but not SPS-7 induced a significant immunosuppressive effect as evidenced by depletion of marginal zone B cells, down-regulation of sphingosine-1-phosphate receptors and a decrease in peripheral blood lymphocytes. In conclusion, the data suggest that SPS-7 is not an immunosuppressant while induces anticancer effect against HRPC through inhibition of Akt/mTOR/p70S6K pathwaysthat down-regulate protein levels of both c-Myc and cyclin D1, leading to G1 arrest of cell cycle and subsequent apoptosis. The data also indicate the potential of SPS-7 since PI3K/Akt signalingis responsive for the genomic alterations in prostate cancer.

Abstract
OBJECTIVES To explore the genetic variation sites of caveolin (CAV) and their correlation with sudden unexplained death (SUD). METHODS The blood samples were collected from SUD group (71 cases), coronary artery disease (CAD) group (62 cases) and control group (60 cases), respectively. The genome DNA were extracted and sequencing was performed directly by amplifying gene coding region and exon-intron splicing region of CAV1 and CAV3 using PCR. The type of heritable variation of CVA was confirmed and statistical analysis was performed. RESULTS A total of 4 variation sites that maybe significative were identified in SUD group, and two were newfound which were CAV1: c.45C>T (T15T) and CAV1:c.512G>A (R171H), and two were SNP loci which were CAV1:c.246C>T (rs35242077) and CAV3:c.99C>T (rs1008642) and had significant difference (P<0.05) in allele and genotype frequencies between SUD and control groups. Forementioned variation sites were not found in CAD group. CONCLUSIONS The variants of CAV1 and CAV3 may be correlated with a part of SUD group.

Abstract
Background Lower urinary tract symptoms (LUTS) and overactive bladder (OAB) symptoms have a substantial effect on quality of life (QoL). We report QoL and mental health results from a LUTS prevalence study in three Asian countries. Methods A cross-sectional, population-representative, internet-based study among individuals aged ≥40 years in China, Taiwan and South Korea. Instruments included: Overactive Bladder Symptom Score (OABSS); International Prostate Symptom Score (IPSS); other International Continence Society (ICS) symptom questions; health-related QoL 12-item short-form (HRQoL-SF12v2); Work Limitations Questionnaire (WLQ); Hospital Anxiety and Depression Scale (HADS). Presence of LUTS was determined according to ICS criteria, with three symptom groups (storage, voiding and post-micturition). Post-stratification weighting matched the age and sex population distribution per country. Initial data analyses were based on descriptive statistics. Significance testing undertaken post hoc included: independent-samples t-test (differences in HRQoL between sexes and between individuals with/without LUTS; relationship between HRQoL score and OABSS; differences in HADS anxiety and depression scores between individuals with/without LUTS; association between HADS anxiety/depression scores and OABSS), chi-square test (association between LUTS prevalence and workplace productivity) and analysis of variance (differences in HRQoL score and in HADS anxiety/depression scores between individuals with different symptom groups, association between HADS anxiety/depression scores and IPSS). Results In total, 8284 participants were included. HRQoL scores were significantly worse (p < 0.001) among individuals with versus without LUTS (ICS criteria): mean physical health domain scores were 61.1 (standard deviation [SD], 20.1) and 76.7 (17.0), respectively; corresponding mental health domain scores were 34.8 (12.7) and 43.7 (10.7). Workplace productivity was best among individuals without LUTS (difficulties reported by 2–3% of individuals), and worst in those with all three ICS symptom groups (difficulties reported by 29–38% of individuals; p = 0.001). Mean HADS scores showed significantly worse (p < 0.001) levels of anxiety and depression among individuals with versus without LUTS: anxiety, 6.5 (SD, 3.7) and 4.0 (3.3); corresponding mean depression scores were 6.8 (4.3) and 4.2 (3.6). Increasing OAB severity was also associated with decreasing HRQoL physical and mental health scores. Conclusion LUTS and increasing OAB severity are both associated with impaired QoL, reduced workplace productivity, and increased tendency towards anxiety and depression. These results highlight the need to ensure that individuals with LUTS receive appropriate, effective treatment.

Abstract
Objective The aim of the present study was to determine the prevalence of overactive bladder (OAB) in individuals aged ≥40 years in China, Taiwan, and South Korea. Methods The present cross‐sectional population‐representative Internet‐based study investigated OAB symptoms in men and women aged ≥40 years using the overactive bladder symptom score. Additional instruments included the International Index of Erectile Function (men only) and the Sexual Quality of Life – Female (women only) questionnaires, as well as Patient Perception of Bladder Condition (PPBC). Results In all, 8284 individuals participated in the study. The prevalence of OAB was 20.8% overall (women 22.1%, men 19.5%) and increased significantly with age, from 10.8% in those aged 40–44 years to 27.9% in those aged >60 years (P = .001). The presence of comorbid conditions (e.g. neurological disease, diabetes) was associated with a significantly increased prevalence of OAB. Increasing symptom severity was associated with significantly worsening patient perception of bladder condition responses. Just under half (48%) of those with no OAB had no lower urinary tract symptoms (LUTS), whereas 88% of those with severe symptoms had all 3 LUTS (International Continence Society definition) symptom categories (voiding, post‐micturition, and storage symptoms). Of those without OAB, 10% reported visiting healthcare professionals for urinary symptoms, compared with 64% of those with severe OAB symptoms (P = .001). Increased symptom severity was significantly associated with lower sexual quality of life in both men and women. Conclusions OAB symptoms were found to affect 1 in 5 individuals aged ≥40 years in China, Taiwan, and South Korea, becoming more common with increasing age. The results suggest that many more individuals with OAB could benefit by consulting healthcare professionals.

Abstract
Introduction Few population-based data are available evaluating the prevalence of lower urinary tract symptoms (LUTS) in Asia. The objective of our study was to determine LUTS prevalence in China, Taiwan, and South Korea using International Continence Society (ICS) 2002 criteria. Methods An Internet-based self-administered survey among individuals aged at least 40 years with the ability to use a computer and to read the local language. Survey questions included ICS symptom definitions and the international prostate symptom score (IPSS). Data analysis was based on descriptive statistics and post hoc significance testing. Results There were 8284 participants, of whom 51% were women and 34% were aged at least 60 years. LUTS prevalence was slightly higher in men than women (62.8% vs. 59.6%; p = 0.004), increasing significantly with age (p = 0.001). All three ICS symptom groups (voiding, storage, and post-micturition) were present in 35% of individuals with LUTS. Symptoms with the highest overall prevalence were nocturia, frequency, incomplete emptying, and terminal dribble. The most bothersome symptoms were terminal dribble, nocturia, and urgency. According to IPSS scores, 87% of participants had at least mild symptoms; 43% of those aged over 60 years had moderate/severe symptoms. The percentage of participants with any LUTS who had visited healthcare professionals because of urinary symptoms was 26%, rising to 45% amongst individuals with all three symptom groups (p = 0.001 vs. other ICS symptom groups). Conclusions LUTS are highly prevalent in men and women aged at least 40 years who participated in this study in China, Taiwan, and South Korea and increases with increasing age. A minority of individuals with LUTS seek healthcare and our results suggest an increased patient awareness of LUTS is required. Funding Astellas Pharma Singapore Pte. Ltd.

Abstract
Prostatitis is a common condition in adult men of all ages. Uropathogenic Escherichia coli (UPEC) are most frequent pathogen involved in bacterial prostatitis by refluxing the infected urine into prostatic ducts and resulting in an ascending urethral infection. However, the study about the mechanisms of UPEC to invade, replicate and persist in normal prostate epithelial cell is only few. Given the fact that UPEC is pathogen most frequently involved in prostatitis and that testosterone has been demonstrated to attenuate prostate inflammation caused by other etiologies. In this study we investigated whether the testosterone reduces the prostatitis and related mechanism by regulating IFN-γ/STAT1 signaling pathway. In the current study aimed to clarify whether testosterone influences the process of UPEC-induced prostate inflammation and invasion into the prostate epithelial cells. In addition, we set up a normal prostate cell model for UPEC infection to evaluate the ability to invade the urothelial cells as well as the colonization of intercellular bacterial communities in vitro. By using the model, we examine the effects of testosterone to suppress effectively the invasion and survival of UPEC in the prostate cells, and inhibit LPS-induced inflammatory responses through the JAK/STAT1 pathway have also been indicated. Our results demonstrated testosterone not only suppressed the invasion and colonization of UPEC, but also inhibited the expression of pro-inflammatory IL-1β, IL-6 and IL-8 cytokines expression induced by UPEC in a dose-dependent manner. We found the effective dose of testosterone to suppress UPEC infect prostate cells may be appropriate under 40μg/ml. Our data also revealed 20μg/ml testosterone treated PZ-HPV-7 cells significantly suppressed the LPS-induced JAK/STAT1 pathway and inflammatory responses, and reached to maximal effects at 40μg/ml treatment. These results indicate that testosterone plays an anti-inflammatory role in LPS-induced prostate cell inflammation by down-regulating JAK/STAT1 signaling pathway. Interestingly, the JAK inhibitor and testosterone for 24hr pretreatment rather markedly induced the colonization of UPEC in the PZ-HPV-7 cells. Based on the above data, the suppression of UPEC colonization in the prostate cells by testosterone seems to be unrelated with JAK/STAT signaling pathway, whereas the JAK may involve into the UPEC infection. Summing up these data, our findings have demonstrated the suppressive effects of testosterone on the invasion and survival of UPEC and induced inflammation in prostate epithelial cells. These findings indicate the action mechanism of testosterone as an anti-inflammatory mediator in the prostate cells is regulated through JAK/STAT1 signaling pathway, may be beneficial in treating prostate inflammation. Altogether, this study has provided the possibility that using testosterone in the prevention and clinical treatment of prostatitis is a new direction.

Abstract
Due to the negative autopsy and without cardiac structural abnormalities, unexpected sudden cardiac death (USCD) is always a tough issue for forensic pathological expertise. USCD may be associated with parts of fatal arrhythmic diseases. These arrhythmic diseases may be caused by disorders of cardiac ion channels or channel-related proteins. Caveolin can combine with multiple myocardial ion channel proteins through its scaffolding regions and plays an important role in maintaining the depolarization and repolarization of cardiac action potential. When the structure and function of caveolin are affected by gene mutations or abnormal protein expression, the functions of the regulated ion channels are correspondingly impaired, which leads to the occurrence of multiple channelopathies, arrhythmia or even sudden cardiac death. It is important to study the effects of caveolin on the functions of ion channels for exploring the mechanisms of malignant arrhythmia and sudden cardiac death.

Abstract
The use of peptides that target cancer cells and induce anticancer activities through various mechanisms is developing as a potential anticancer strategy. KUD983, an enantiomerically pure β-dipeptide derivative, displays potent activity against hormone-refractory prostate cancer (HRPC) PC-3 and DU145 cells with submicromolar IC50. KUD983 induced G1 arrest of the cell cycle and subsequent apoptosis associated with down-regulation of several related proteins including cyclin D1, cyclin E and Cdk4, and the de-phosphorylation of RB. The levels of nuclear and total c-Myc protein, which could increase the expression of both cyclin D1 and cyclin E, were profoundly inhibited by KUD983. Furthermore, it inhibited PI3K/Akt and mTOR/p70S6K/4E-BP1 pathways, the key signaling in multiple cellular functions. The transient transfection of constitutively active myristylated Akt (myr-Akt) cDNA significantly rescued KUD983-induced caspase activation but did not blunt the inhibition of mTOR/p70S6K/4E-BP1 signaling cascade suggesting the presence of both Akt-dependent and -independent pathways. Moreover, KUD983-induced effect was enhanced with the down-regulation of anti-apoptotic Bcl-2 members (e.g., Bcl-2, and Mcl-1) and IAP family members (e.g., survivin). Notably, KUD983 induced autophagic cell death using confocal microscopic examination, tracking the level of conversion of LC3-I to LC3-II and flow cytometric detection of acidic vesicular organelles-positive cells. In conclusion, the data suggest that KUD983 is an anticancer β-dipeptide against HRPCs through the inhibition of cell proliferation and induction of apoptotic and autophagic cell death. The suppression of signaling pathways regulated by c-Myc, PI3K/Akt and mTOR/p70S6K/4E-BP1 and the collaboration with down-regulation of Mcl-1 and survivin may explain KUD983-induced anti-HRPC mechanism.

Abstract
Inflammatory processes have a detrimental role in the pathophysiology of ischemic stroke. However, little is known about the endogenous anti-inflammatory mechanisms in ischemic brain. Here, we identify CXCL14 as a critical mediator of these mechanisms. CXCL14 levels were upregulated in the ischemic brains of humans and rodents. Moreover, hypoxia inducible factor-1α (HIF-1α) drives hypoxia- or cerebral ischemia (CI)-dependent CXCL14 expression via directly binding to the CXCL14 promoter. Depletion of CXCL14 inhibited the accumulation of immature dendritic cells (iDC) or regulatory T cells (Treg) and increased the infarct volume, whereas the supplementation of CXCL14 had the opposite effects. CXCL14 promoted the adhesion, migration, and homing of circulating CD11c+ iDC to the ischemic tissue via the upregulation of the cellular prion protein (PrPC), PECAM-1, and MMPs. The accumulation of Treg in ischemic areas of the brain was mediated through a cooperative effect of CXCL14 and iDC-secreted IL-2-induced Treg differentiation. Interestingly, CXCL14 largely promoted IL-2-induced Treg differentiation. These findings indicate that CXCL14 is a critical immunomodulator involved in the stroke-induced inflammatory reaction. Passive CXCL14 supplementation provides a tractable path for clinical translation in the improvement of stroke-induced neuroinflammation.

Abstract
Background We have previously described the association between rheumatoid arthritis (RA) prevalence and the two mutY Homolog (E. coli) (MUTYH) SNPs (rs3219463 and rs3219476) among the Taiwanese population. This present study will aim to elucidate whether the SNPs can alter the expression of EGFR in the progression of RA. Methods The cohort study included 368 Taiwan’s Han Chinese RA patients and 364 healthy controls. Blood samples collected from the participants were analyzed to determine their serum MUTYH levels and to identify rs3219463 SNP of MUTYH from their genomic DNA. Results Our data resulted in a statistically significant difference in genotype frequency distributions at rs3219463 for RA patients and controls (p < 0.0002). Also, the patients with G carrier at rs3219463 were less likely to suffer from painful joints (p < 0.006) and DAS28 scores (p < 0.003). Furthermore, the increase in serum level of MUTYH was also observed in RA patients (p < 0.005). Conclusions Our study showed that RA is associated with rs3219463 SNP in EGFR gene and an increased serum level of the MUTYH protein. These findings suggest MUTYH is worthy of further investigation as a therapeutic target for RA.

Abstract
PURPOSE To assess the angiographic and clinical outcomes in patients with erectile dysfunction and isolated penile artery stenoses treated by balloon angioplasty. METHODS In this prospective study, 22 patients (mean age 61.0±7.6 years, range 50-79) with erectile dysfunction and 34 isolated penile artery stenoses (mean 74.9%±9.1%) were enrolled and underwent balloon angioplasty. The mean International Index for Erectile Function-5 (IIEF-5) score at baseline was 10.3±4.5. The mean lesion length was 11.1±9.0 mm (mean reference vessel diameter 1.7±0.4 mm). The primary endpoint was in-segment restenosis ≥50% by pelvic computed tomography angiography (CTA) at 8 months. The 1-year sustained clinical success (IIEF-5 score ≥22 or a ≥4-point change in the IIEF-5 score and no later decline by ≥4) was the secondary outcome measure. RESULTS Procedural success was achieved in 31 (91%) of 34 stenotic lesions; there was 1 flow-limiting dissection and 2 arteries with >30% residual stenosis. At 8 months, 14 of 34 lesions in 13 of 22 patients had CTA-documented binary restenosis. At 1 year, sustained clinical success was achieved in 11 of 22 patients. Of the 9 patients not developing binary restenosis, 8 achieved sustained clinical success. CONCLUSION Our findings establish the safety and efficacy of penile artery angioplasty for patients with erectile dysfunction and isolated penile artery stenoses. They also highlight the unmet need for a more enduring treatment strategy for penile artery stenotic disease.

Abstract
In the diagnosis of late-onset hypogonadism (LOH), the Androgen Deficiency in the Aging Male (ADAM) questionnaire or Aging Males' Symptoms (AMS) scale can be used to assess related symptoms. Subsequently, blood tests are used to measure serum testosterone levels. However, results obtained using ADAM and AMS have revealed no significant correlations between ADAM and AMS scores and LOH, and the rate of misclassification is high. Recently, many studies have reported significant associations between clinical conditions such as the metabolic syndrome, obesity, lower urinary tract symptoms, and LOH. In this study, we sampled 772 clinical cases of men who completed both a health checkup and two questionnaires (ADAM and AMS). The data were obtained from the largest medical center in Taiwan. Two well-known classification techniques, the decision tree (DT) and logistic regression, were used to construct LOH prediction models on the basis of the aforementioned features. The results indicate that although the sensitivity of ADAM is the highest (0.878), it has the lowest specificity (0.099), which implies that ADAM overestimates LOH occurrence. In addition, DT combined with the AdaBoost technique (AdaBoost DT) has the second highest sensitivity (0.861) and specificity (0.842), resulting in having the best accuracy (0.851) among all classifiers. AdaBoost DT can provide robust predictions that will aid clinical decisions and can help medical staff in accurately assessing the possibilities of LOH occurrence.

Abstract
Endothelial progenitor cells (EPCs) are bone marrow-derived endothelial cells capable of circulating, proliferating, and differentiating into mature endothelial cells. Circulating EPCs can be directly recruited to some extent at sites of injury, and their administration could accelerate repair or endothelialization of the damaged tissue. We investigated the effects of intracavernous injections of EPCs into the corpora cavernosa of rats with erectile dysfunction (ED) caused by bilateral cavernous nerve (CN) injury. Overall, 24 male Sprague-Dawley rats were randomized into three groups: sham surgery, vehicle-only, or EPC treatment. Rats in the EPC treatment and vehicle-only groups were subjected to bilateral CN injury before injection of EPCs or vehicle, respectively, into the corpora cavernosa. Four weeks after surgery, erectile function was assessed by measuring maximum intracavernosal pressure (ICP), change in ICP, area under the ICP curve, and ratio of change in ICP and mean arterial pressure (MAP; ΔICP/MAP). Penile tissue was histomorphometrically analyzed for the expression of neural nitric oxide synthase (nNOS), neurofilament-1 (NF-1), von Willebrand factor (vWF), endothelial NOS (eNOS), and smooth muscle cell content. Maximum ICP and all other functional parameters of erectile function were significantly reduced in the vehicle-only group vs. the sham and EPC treatment groups (all p < 0.001). Smooth muscle cell content was decreased in the vehicle-only vs. the sham and EPC treatment groups (both p < 0.01). Expressions of vWF and eNOS in the dorsal artery were significantly higher in the EPC treatment than the vehicle-only group (p < 0.05). In conclusion, EPC treatment restored erectile function in a rat model of bilateral CN injury through recruitment of EPCs toward the dorsal artery and preservation of smooth muscle cells in the corpus cavernosum. These findings elucidate the therapeutic potential of EPCs for treating ED in humans.

Abstract
INTRODUCTION Testosterone deficiency increases the cardiovascular disease (CVD) risk. AIM To evaluate the effect of erectile dysfunction (ED), sexual frequency and hypogonadal symptoms on CVD risk. METHODS A total of 395 hypogonadal men aged 45-74 years were surveyed using the Androgen Deficiency in the Aging Male and the International Index of Erectile Function. MAIN OUTCOME MEASURES The 10-year CVD risk was measured with the Framingham Risk Score. Logistic regression was performed to obtain the odds ratios of sexual function and hypogonadal symptoms for a 10-year CVD risk ≥20% (high risk). RESULTS The mean age was 56.1 ± 6.7 years. The mean 10-year CVD risk of the whole cohort was 18.1% ± 11.4%, while 131 subjects (33.2%) were classified as high risk. Logistic regression revealed that ED severity was associated with CVD risk [OR = 2.37 (CI 1.24-4.51) for mild-to-moderate ED, OR = 4.39 (1.78-8.43) for moderate ED and OR = 12.81 (4.65-26.11) for severe ED]. Compared to sexual frequency <1 per month, sexual frequency ≥4 decreased the risk of high CVD risk [OR = 0.35 (0.23-0.780)]. Loss of libido [OR = 2.95 (1.91-4.12)] and less strong erection [OR = 3.87 (CI 2.11-4.95)] increased the risk of high CVD risk. All remained significant after adjustment for age and testosterone. CONCLUSIONS ED, decreased sexual frequency and loss of libido predict a high 10-year CVD risk in hypogonadal men.

Abstract
Both periodontitis and osteoporosis have similar sign of bone resorption in nature. However, the relationship of the severity between these 2 bone-loss diseases is still uncertain.The aim of this study was to investigate the association between the severity of osteoporosis and periodontitis regarding the impact of oral hygiene maintenance. In total, 35,127 osteoporosis patients and 50,498 comparisons were derived from the Longitudinal Health Insurance Database of Taiwan between 2000 and 2010. The population was subdivided into groups according to the different level oral hygiene maintenance and the severity of periodontitis and osteoporosis. The association between osteoporosis and periodontitis was estimated by multinomial logistic regression and rank correlation by Kendall rank correlation test, presented by odds ratio (OR), and 5% confidence intervals (CIs).After controlling the age, sex, and comorbidities, variables in the good oral hygiene maintenance population, we found that periodontitis raised 1.29-fold risk of osteoporosis (95% CI = 1.12-1.49); the risk of osteoporosis was increased with the elevated severity of periodontitis from 1.27 (95% CI = 1.08-1.48) to 1.38 (95% CI = 1.01-1.89). There is a positive correlation between the severity of periodontitis and osteoporosis occurrence in this population (OR = 1.27-1.46; Kendall rank correlation test P = 0.0003). In the poor oral hygiene maintenance population, periodontitis patients had 6.02-fold risk of osteoporosis than those who without periodontitis (95% CI = 4.65-7.81); the risk of osteoporosis was increased with periodontitis severity from 5.96 (95% CI = 4.48-7.92) to 6.37 (95% CI = 3.36-12.1).This result indicated the periodontitis and osteoporosis are conjunctive. The sudden periodontal breakdown of those who with good oral hygiene maintenance might be an indicator for the risk of osteoporosis; if those who were diagnosed as osteoporosis must pay more attention to their periodontal health. Good oral hygiene maintenance might be a crucial factor for preventing the deterioration of osteoporosis progressing; the oral hygiene maintenance plays a significant influence on the association between periodontitis and osteoporosis.

Abstract
Stroke is a result of cerebral ischemia that triggers a cascade of both physiological and biochemical events. No effective treatment is available for stroke; however, stem cells have the potential to rescue tissue from the effects of stroke. Adipose-derived stem cells (ADSCs) are an abundant source of adult stem cells; therefore, ADSC therapy can be considered as a future strategy for regenerative medicine. However, more research is required to improve the effectiveness of transplanted ADSCs as a treatment for stroke in the mouse stroke model. Ligustilide, isolated from the herb Angelica sinensis, exhibits a protective effect on neurons and inhibits inflammation. We also demonstrated that ligustilide treatment increases the expression levels of homing factors such as SDF-1 and CXCR4. In the present study, we evaluated the therapeutic effects of ADSC transplantation and ligustilide treatment in a mouse thromboembolic stroke model by behavioral tests, including beam walking, locomotor activity, and rotarod analysis. ADSCs pretreated with ligustilide were transplanted into the brains of stroke mice. The results showed that the therapeutic effect of ADSCs pretreated with ligustilide was better than that of ADSCs without ligustilide pretreatment. There was no difference between the recovery of mice treated by ADSC transplantation combined with subcutaneous ligustilide injection and that of mice treated only with ADSCs. The TUNEL assay showed fewer apoptotic cells in the brains of mice transplanted with ADSCs pretreated with ligustilide as well as in those without pretreatment. In summary, pretreatment of ADSCs with ligustilide improves the therapeutic efficacy of ADSC transplantation. The results of this study will help improve stem cell therapies being developed for future clinical applications.

Abstract
Understanding stem cell homing, which is governed by environmental signals from the surrounding niche, is important for developing effective stem cell-based repair strategies. The molecular mechanism by which the brain under ischemic stress recruits bone marrow-derived cells (BMDCs) to the vascular niche remains poorly characterized. Here we report that hypoxia-inducible factor-1α (HIF-1α) activation upregulates pituitary adenylate cyclase-activating peptide 38 (PACAP38), which in turn activates PACAP type 1 receptor (PAC1) under hypoxia in vitro and cerebral ischemia in vivo. BMDCs homing to endothelial cells in the ischemic brain are mediated by HIF-1α activation of the PACAP38-PAC1 signaling cascade followed by upregulation of cellular prion protein and α6-integrin to enhance the ability of BMDCs to bind laminin in the vascular niche. Exogenous PACAP38 confers a similar effect in facilitating BMDCs homing into the ischemic brain, resulting in reduction of ischemic brain injury. These findings suggest a novel HIF-1α-activated PACAP38-PAC1 signaling process in initiating BMDCs homing into the ischemic brain for reducing brain injury and enhancing functional recovery after ischemic stroke.

Abstract
AIM Lung cancer is the leading cause of cancer-related death worldwide. Interleukin-4 (IL-4) is a typical pleiotropic T helper 2 cytokine involved in immunology during carcinogenesis. The present study aimed at evaluating the contribution of IL-4 promoter T-1099G (rs2243248), C-589T (rs2243250), C-33T (rs2070874) genetic polymorphisms to the risk of lung cancer in Taiwan. MATERIALS AND METHODS The contributions of the promoter IL-4 polymorphic genotypes to lung cancer risk were investigated in 358 lung cancer patients and 716 age- and gender-matched healthy controls. In addition, the interaction between IL-4 and individual smoking status was also evaluated. RESULTS The percentages of CC, CT and TT for IL-4 C-589T genotypes were differentially represented as 69.0%, 26.5% and 4.5% in the lung-cancer patient group and 61.3%, 30.4% and 8.3% in the non-cancer control group, respectively (p=0.0156). The TT genotype carriers were of lower risk for lung cancer (odds ratio (OR)=0.48, 95% confidence interval (CI)=0.27-0.86, p=0.0106) than the CC genotype carriers. We also analyzed the allelic frequency distributions and the results showed that the T allele of IL-4 C-589T conducted a protective effect on lung cancer susceptibility (p=0.0022). On the contrary, there was no difference in the distribution of genotypic or allelic frequencies among patients and controls for the IL-4 promoter T-1099G and C-33T. CONCLUSION The TT genotype of IL-4 C-589T compared to the CC wild-type genotype may have a protective effect on lung cancer risk in Taiwan and may serve as an early detection and prediction marker.

Abstract
BACKGROUND Drug repurposing of phentolamine, an α-adrenoceptor antagonist, as an anticancer agent has been studied in human castration-resistant prostate cancer (CRPC). METHODS Cell proliferation was examined by sulforhodamine B and CFSE staining assays. Cell cycle progression and mitochondrial membrane potential (ΔΨm) were detected by flow cytometric analysis. Protein expression was detected by Western blotting. Effect on tubulin/microtubule was determined using confocal immunofluorescence microscopic examination, microtubule assembly detection, tubulin turbidity assay, and binding assay. Several assessments were used to characterize apoptotic signaling pathways and combinatory effect. RESULTS Phentolamine induced anti-proliferative effect in PC-3 and DU-145, two CRPC cell lines, and P-glycoprotein (P-gp) overexpressing cells. This effect was not significantly reduced in paclitaxel-resistant cells. Rhodamine 123 efflux assay showed that phentolamine was not a P-gp substrate. Phentolamine induced mitotic arrest of the cell cycle and formation of hyperdiploid cells, followed by an increase of apoptosis. Mitotic arrest was confirmed by cyclin B1 up-regulation, Cdk1 activation, and a dramatic increase of mitotic protein phosphorylation. Both in vitro and cellular identification demonstrated that phentolamine, similar to paclitaxel, induced tubulin polymerization and formation of multiple nuclei. Besides, it did not compete with paclitaxel binding on tubulin. Phentolamine induced the phosphorylation and degradation of Bcl-2 and Bcl-xL, two anti-apoptotic Bcl-2 family members, and the loss of ΔΨm indicating the induction of mitochondrial damage. It ultimately induced the activation of caspase-9, -8, and -3 and apoptotic cell death. Moreover, combination treatment with phentolamine and paclitaxel caused a synergistic apoptosis. CONCLUSIONS The data suggest that phentolamine is a potential anticancer agent. In contrast to a wide variety of microtubule disrupting agents, phentolamine induces microtubule assembly, leading to mitotic arrest of the cell cycle which "in turn" induces subsequent mitochondrial damage and activation of related apoptotic signaling pathways in CRPC cells. Furthermore, combination between phentolamine and paclitaxel induces a synergistic apoptotic cell death. Phentolamine has a simple chemical structure and is not a P-gp substrate. Optimization of phentolamine structure may also be a potential approach for further development.

Abstract
AIM The present study aimed at investigating whether X-ray repair cross complementing protein 3 (XRCC3) genotype may serve as a useful marker for detecting leiomyoma and predicting risk. MATERIALS AND METHODS A total of 640 women (166 patients with leiomyoma and 474 healthy controls) were examined for their XRCC3 rs1799794, rs45603942, rs861530, rs3212057, rs1799796, rs861539, rs28903081 genotype. The distributions of genotypic and allelic frequencies between the two groups were compared. RESULTS The results showed that the CT and TT genotypes of XRCC3 rs861539 were associated with increased leiomyoma risk (odds ratio=2.19, 95% confidence interval=1.23-3.90; odds ratio=3.72, 95% confidence interval=1.23-11.26, respectively). On allelic frequency analysis, we found a significant difference in the distribution of the T allelic frequency of the XRCC3 rs861539 (p=5.88 × 10(-5)). None of the other six single nucleotide polymorphisms were associated with altered leiomyoma susceptibility. CONCLUSION The T allele (CT and TT genotypes) of XRCC3 rs861539 contributes to increased risk of leiomyoma among Taiwanese women and may serve as a early detection and predictive marker.

Abstract
The DNA double strand break repair protein XRCC3 plays a central role in removing double strand breaks from the genome and defects in cellular repair capacity is closely related to human cancer initiation. Therefore, we aimed to investigate the contribution of XRCC3 genotypes to individual nasopharyngeal carcinoma (NPC) susceptibility. In this hospital-based population research, the genotyping and analyzing of XRCC3 rs1799794, rs45603942, rs861530, rs3212057, rs1799796, rs861539, rs28903081 in a large Taiwanese population was performed. Totally, 176 NPC patients and 880 age- and gender-matched healthy controls were genotyped and analyzed by PCR-RFLP method. The results showed that there was a differential distribution among NPC and control subjects in the genotypic (P = 0.000488) and allelic (P = 0.0002) frequencies of XRCC3 rs861539. As for the gene-environment interaction, we have firstly provided evidence showing that there is an obvious joint effect of XRCC3 rs861539 CT and TT genotypes with individual smoking habits on increased NPC risk. In conclusion, the T allele of XRCC3 rs861539, interacts with smoking habit in increasing NPC risk, may be an early detection marker for NPC.

Abstract
The association between diabetes and benign prostatic hyperplasia remains inconclusive. In this case-control study, we examined the association of diabetes with benign prostatic enlargement (BPE) using the Longitudinal Health Insurance Database 2000 in Taiwan. In total, 20 152 patients with BPE as cases and 20 152 age-matched patients without BPE were included as controls. Conditional logistic regression analyses were performed to calculate the odds ratio (OR) and corresponding 95% CI for having been previously diagnosed with diabetes between cases and controls. We found that of the 40 304 sampled patients, 9492 (23.6%) had a history of diabetes before the index date. This mean age for the sampled patients was 65.9 with a standard deviation of 12.0 years. A Chi-squared test revealed that there was a significant difference in the prevalence of prior diabetes between cases and controls (25.3% vs. 21.8%, p < 0.001). The conditional logistic regression found that the OR of prior diabetes for cases was 1.21 (95% CI = 1.15-1.27) compared with controls. However, after adjusting for geographic region, monthly income, urbanization level, hypertension, coronary heart disease (CHD), hyperlipidemia, tobacco use disorder, and obesity, the association between prior diabetes and BPE did not reach a statistically significant level (OR = 1.03, 95% CI = 0.98-1.08). In addition, it was noteworthy that hypertension (OR = 1.25, 95% CI = 1.20-1.31), CHD (OR = 1.40, 95% CI = 1.32-1.48), and hyperlipidemia (OR = 1.30, 95% CI = 1.24-1.36) were all significantly associated with BPE. We found that men with a diagnosis of diabetes were not significantly associated with BPE after adjusting for patient's sociodemographic characteristics and comorbidities.

Abstract
OBJECTIVE To investigate whether the therapeutic effect of Ginkgo biloba extract (GBE) in a rat model can improve erectile dysfunction after bilateral cavernous nerve injury. METHODS Forty-three male Sprague-Dawley rats underwent cavernous nerve crush injury and were randomized into 4 groups, including: vehicle only, high-dose GBE, medium-dose GBE, and low-dose GBE. Eight animals underwent sham operation. Four weeks later, erectile function was assessed by cavernous nerve electrostimulation, and penile tissue was collected for histologic analysis. RESULTS Significant recovery of erectile function was observed in the high-dose GBE group in a dose-dependent manner as compared with the vehicle-only group (P <.001). The high-dose GBE group had a significant increase in neurofilament-1 expression (P <.001), preservation of neural nitric oxide synthase nerve fibers of the dorsal penile nerve (P <.05), and increased smooth muscle cell content (P <.001) compared with the vehicle-only group. In addition, high-dose GBE markedly augments the smooth muscle-to-collagen ratio (P <.05) and reduces the apoptotic index. CONCLUSION Administration of GBE increases neuron survival and preserves the neural nitric oxide synthase nerve fiber and contents of the corpus cavernosum after bilateral cavernous nerve injury. These implications indicate the beneficial effects of GBE use in the repair of the cavernous nerve and recovery of erectile function after radical prostatectomy.

Abstract
Type 1 diabetes mellitus (T1DM) is a form of early onset diabetes mellitus characterized by the autoimmune destruction of insulin-producing cells (IPCs), resulting in hyperglycemia and abnormal glucose metabolism. There are currently no treatments available capable of completely curing the symptoms associated with the loss or functional defects of IPCs. Nonetheless, stem cell therapy has demonstrated considerable promise in the replacement of IPCs with immunomodulatory functions to overcome the defects caused by T1DM. Adipose-derived stem cells (ADSCs) are particularly suitable for use in cell transplantation therapy, especially when seeking to avoid the ethical issues and tumorigenic complications commonly associated with embryos or induced pluripotent stem cells. Cell-based treatments have demonstrated therapeutic advantages and clinical applicability of ADSCs in T1DM, ensuring their suitability for transplantation therapy. This manuscript focuses on the benefits and possible mechanisms in a T1DM-relevant model and displays positive results from finished or ongoing human clinical trials. We also discuss and hypothesize potential methods to further enhance the therapeutic efficacy of these efforts, such as a humanized rodent model and gene therapies for IPC clusters, to meet the clinical applicability of the standard.

Abstract
Irisflorentin is an isoflavone component derived from the roots of Belamcanda chinensis (L.) DC. In traditional Chinese medicine, this herb has pharmacological properties to treat inflammatory disorders. Dendritic cells (DCs) are crucial modulators for the development of optimal T-cell immunity and maintenance of tolerance. Aberrant activation of DCs can induce harmful immune responses, and so agents that effectively improve DC properties have great clinical value. We herein investigated the effects of irisflorentin on lipopolysaccharide (LPS)-stimulated maturation of mouse bone marrow-derived DCs in vitro and in the contact hypersensitivity response (CHSR) in vivo. Our results demonstrated that treatment with up to 40 μM irisflorentin does not cause cellular toxicity. Irisflorentin significantly lessened the proinflammatory cytokine production (tumor necrosis factor-α, interleukin-6, and interleukin-12p70) by LPS-stimulated DCs. Irisflorentin also inhibited the expression of LPS-induced major histocompatibility complex class II and costimulatory molecules (CD40 and CD86) on LPS-stimulated DCs. In addition, irisflorentin diminished LPS-stimulated DC-elicited allogeneic T-cell proliferation. Furthermore, irisflorentin significantly interfered with LPS-induced activation of IκB kinase, c-Jun N-terminal kinase, and p38, as well as the nuclear translocation of NF-κB p65. Subsequently, treatment with irisflorentin obviously weakened 2,4-dinitro-1-fluorobenzene-induced delayed-type hypersensitivity. These findings suggest new insights into the role of irisflorentin as an immunotherapeutic adjuvant through its capability to modulate the properties of DCs.

Abstract
Cardiovascular diseases are related to many risk factors, such as diabetes, high blood pressure, smoking, and obesity. Myocardial infarction (MI), a cardiovascular disease, is the most common cause of cardiomyocyte death. In MI, hypoxia induces cardiomyocyte apoptosis; in particular, diabetes combined with MI has a synergistic effect that exacerbates cardiomyocyte death. The hypoxia-inducible factor-1α (HIF1α) transcriptional factor and a BH-3 only protein, Bcl-2 adenovirus E1B 19-kDa interacting protein 3 (BNIP3), are known to play fundamental roles in both adaptive and cell death processes in response to hypoxia. In addition, most cardioprotective studies used H9c2 cells that were not beating, so H9c2 cells may not be the best model for testing cardioprotective effects. Embryonic stem cells (ESCs) are pluripotent stem cells that are able to differentiate into several types of cells, including cardiomyocytes. In this study, we reveal a simple method to differentiate ESCs into cardiomyocytes by using poly-d-lysine-coated plates combined with ITS and N2-containing medium and characterized the ESC-derived cardiomyocytes by cardiomyocyte marker staining. The ESC-derived cardiomyocytes were used to investigate the protective effect of salvianolic acid B (Sal-B) in high glucose combined with hypoxic conditions to mimic diabetes patients with ischemia. The results of MTT and TUNEL assays indicate that Sal-B suppresses the apoptotic effect of treatment with high glucose combined with hypoxia in ESC-derived cardiomyocytes. In particular, Sal-B inhibited HIF1α, BNIP3, and cleavage caspase 3 expression levels, thereby suppressing apoptosis. This is the first study to mention the correlation between BNIP3 and Sal-B for cardioprotective effects. In conclusion, we suggest that Sal-B may be suitable for use as a future cardioprotective medicine.

Abstract
The pluripotent stem cells, including embryonic stem cells (ESCs), are capable of self-renewal and differentiation into any cell type, thus making them the focus of many clinical application studies. However, the efficiency of ESCs differentiated into neurons needs to improve. In this study, we tried to increase efficiently to a neural fate in the presence of various transitional Chinese medicines through a three-step differentiation strategy. From extracts of 10 transitional Chinese medicine candidates, we determined that Sambucus williamsii (SW) extract triggers the up-regulation of Nestin and Tuj1 (neuron cells markers) gene expression levels. After determining the different concentrations of SW extract, the number of neurons in the 200 μg/ml SW extract group was higher than the control, 50, 100, and 400 μg/ml SW extract groups. In addition, the number of neurons in the 200 μg/ml SW extract group was higher and higher after each time passage (three times). We also detected the Oct4, Sox2 (stem cells markers), Tuj1, and Nestin genes expression levels by RT-PCR. In the differentiated process, Oct4 and Sox2 genes decreased while the Tuj1 and Nestin genes expression levels increased. In summary, we demonstrated that SW could induce pluripotent stem cells differentiated into neurons. Thus, SW might become a powerful material for neurons–differentiating strategies.

Abstract
Parkinson’s disease (PD) is a degenerative disorder of the central nervous system that is characterized by progressive loss of dopaminergic neurons in the substantia nigra pars compacta as well as motor impairment. Aggregation of α-synuclein in neuronal cells plays a key role in this disease. At present, therapeutics for PD provides moderate symptomatic benefits, but it is not able to delay the development of the disease. Current efforts toward the treatment of PD are to identify new drugs that slow or arrest the progressive course of PD by interfering with a disease-specific pathogenetic process in PD patients. Irisflorentin derived from the roots of Belamcanda chinensis (L.) DC. is an herb which has been used for the treatment of inflammatory disorders in traditional Chinese medicine. The purpose of the present study was to assess the potential for irisflorentin to ameliorate PD in Caenorhabditis elegans models. Our data reveal that irisflorentin prevents α-synuclein accumulation in the transgenic Caenorhabditis elegans model and also improves dopaminergic neuron degeneration, food-sensing behavior, and life-span in a 6-hydroxydopamine-induced Caenorhabditis elegans model, thus indicating its potential as a anti-parkinsonian drug candidate. Irisflorentin may exert its effects by promoting rpn-3 expression to enhance the activity of proteasomes and down-regulating egl-1 expression to block apoptosis pathways. These findings encourage further investigation on irisflorentin as a possible potent agent for PD treatment.

Abstract
BACKGROUND Hormone-refractory prostate cancer (HRPC), which is resistant to hormone therapy, is a major obstacle in clinical treatment. An approach to inhibit HRPC growth and ultimately to kill cancers is highly demanded. RESULTS KUD773 induced the anti-proliferative effect and subsequent apoptosis in PC-3 and DU-145 (two HRPC cell lines); whereas, it showed less active in normal prostate cells. Further examination showed that KUD773 inhibited tubulin polymerization and induced an increase of mitotic phosphoproteins and polo-like kinase 1 (PLK1) phosphorylation, indicating a mitotic arrest of the cell cycle through an anti-tubulin action. The kinase assay demonstrated that KUD773 inhibited Aurora A activity. KUD773 induced an increase of Cdk1 phosphorylation at Thr(161) (a stimulatory phosphorylation site) and a decrease of phosphorylation at Tyr(15) (an inhibitory phosphorylation site), suggesting the activation of Cdk1. The data were substantiated by an up-regulation of cyclin B1 (a Cdk1 partner). Furthermore, KUD773 induced the phosphorylation and subsequent down-regulation of Bcl-2 and activation of caspase cascades. CONCLUSIONS The data suggest that KUD773 induces apoptotic signaling in a sequential manner. It inhibits tubulin polymerization associated with an anti-Aurora A activity, leading to Cdk1 activation and mitotic arrest of the cell cycle that in turn induces Bcl-2 degradation and a subsequent caspase activation in HRPCs.

Abstract
Embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) are considered the most powerful in terms of differentiating into three-germ-layer cells. However, maintaining self-renewing ESCs and iPSCs in vitro requires leukemia-induced factor (LIF), an expensive reagent. Here we describe a less expensive compound that may serve as a LIF substitute-salvianolic acid B (Sal B), a Salvia miltiorrhiza extract. We found that Sal B is capable of upregulating Oct4 and Sox2, two genes considered important for the maintenance of ESC pluripotency. Our MTT data indicate that instead of triggering cell death, Sal B induced cell proliferation, especially at optimum concentrations of 0.01 nM and 0.1 nM. Other results indicate that compared to non-LIF controls, Sal B-treated ESCs expressed higher levels of several stem cell markers while still maintaining differentiation into three-germ-layer cells after six passages. Further, we found that Sal B triggers the Jak2-Stat3 and EGFR-ERK1/2 signaling pathways. Following Sal B treatment, (a) levels of phosphorylated (p)-Jak2, p-Stat3, p-EGFR, and p-ERK proteins all increased; (b) these increases were suppressed by AG490 (a Jak2 inhibitor) and ZD1839 (an EGFR inhibitor); and (c) cytokines associated with the Jak2-Stat3 signaling pathway were upregulated. Our findings suggest that Sal B can be used as a LIF replacement for maintaining ESC pluripotency while increasing cell proliferation.

Abstract
Background Some studies suggested that psychological stress may be associated with the severity and duration of infectious diseases. In this population-based study, we investigated associations between depressive disorder (DD) and pneumonia outcomes in Taiwan with a large-scale database from the National Health Insurance. Methods Our study defined 112,198 patients who were hospitalized with a principal diagnosis of pneumonia. We defined their admission date for treatment of pneumonia as the index date. Subsequently, we selected 2,394 patients with DD within 3 years prior to their index date and 11,970 matched patients without DD. We carried out separate conditional logistic regressions to explore the association of clinical pneumonia treatment outcome (ICU admission, use of mechanical ventilation, acute respiratory failure and in-hospital death) with previously diagnosed DD. Results Patients with DD had a significantly higher probability of an intensive care unit admission (18.1% vs. 12.9%; p<0.001), need for mechanical ventilation (21.9% vs. 18.1%; p<0.001) and in-hospital death (10.4% vs. 9.0%; p = 0.025) than patients without DD. The study showed that pneumonia patients with DD were respectively 1.41- (95% CI: 1.25∼1.59, p<0.001), 1.28- (95% CI: 1.14∼1.43, p<0.001), and 1.17- times (95% CI: 1.01∼1.36, p = 0.039) greater odds of being admitted to the ICU, need for mechanical ventilation, and in-hospital death than patients without DD after adjusting for monthly income, urbanization level, geographic region and Charlson Comorbidity Index score. Conclusions In conclusion, we found that pneumonia patients with DD were associated with poor treatment outcomes compared to patients without DD.

Abstract
BACKGROUND Psoriasis is a prevalent autoimmune disorder. Various studies have reported on the relationship between psoriasis and chronic diseases but very few have explored the association between psoriasis and subsequent acute infection. This retrospective cohort study aimed to compare the risk of pneumonia between subjects with and those without psoriasis. METHODS The medical records of 14,022 patients with psoriasis and 14,022 without psoriasis were obtained from the Taiwan Longitudinal Health Insurance Database 2000. Each patient was followed-up for a three-year period. Cox proportional hazard regressions were performed to compare difference of subsequent pneumonia incidence between subjects with and those without psoriasis. RESULTS There were 206 (1.47%) subjects with psoriasis and 138 (0.98%) without psoriasis hospitalized for pneumonia. By Cox proportional hazard regressions analysis, the HR (hazard ratio) of pneumonia requiring hospitalization for patients with psoriasis was 1.50 (95% confidence interval [CI]: 1.21-1.86) compared to patients without psoriasis. The adjusted HR was 1.40 (95% CI: 1.12-1.73). The adjusted HR of pneumonia hospitalization for subjects with mild and severe psoriasis was 1.36 (95% CI: 1.09-1.70) and 1.68 (95% CI: 1.12-2.52), respectively, compared to those without psoriasis. CONCLUSIONS Patients with psoriasis have significantly higher incidence of pneumonia compared to those without psoriasis.

Abstract
INTRODUCTION While the epidemiology of testosterone deficiency has been well described in men with previously known type 2 diabetes mellitus (T2DM), it was less reported in those with untreated, newly diagnosed T2DM. AIM The aim of this study was to investigate the prevalence and the risk factors of testosterone deficiency of men with newly diagnosed T2DM. METHODS The cross-sectional study included 105 men (mean age: 61.2 ± 6.8 years) with previously known T2DM and another 81 (57.8 ± 8.8 years) with newly diagnosed T2DM. All received health checkup and sex hormone measurement at our institute in 2009. MAIN OUTCOME MEASURES We calculated the prevalence and explored the risk factors of low total (<300 ng/dL) and free (<6 ng/dL) testosterone in men with newly diagnosed and previously known T2DM. RESULTS Men with previously known T2DM were older and had higher diastolic pressure and greater fasting glucose. There was no significant difference in total (358.0 [155.0] ng/dL vs. 363.0 [154.0] ng/dL, P=0.68) and free (7.2 [2.5] ng/dL vs. 7.4 [2.4]ng/dL, P=0.84) testosterone and sex-hormone binding globulin (SHBG) (27.3 [22.3]nmol/L vs. 28.7 [14.9]nmol/L, P=0.46). The prevalence of low total and free testosterone was 28.4% and 21.0%, respectively, in men with newly diagnosed T2DM, and was 26.7% and 19.0% in those with previously known T2DM. In men with previously known T2DM, better glycemic control (HbA1c <7%) was associated with a higher level of total testosterone and a lower risk of low total testosterone. Men with newly diagnosed and previously known T2DM shared similar risk factors of low total testosterone, including high HbA1c (≥ 7%), low SHBG (<20 nmol/L), obesity, hyperuricemia, hypertriglycemia, and metabolic syndrome. Elevated prostate-specific antigen was a protective factor of low total testosterone. However, none of these factors was associated with low free testosterone. CONCLUSIONS The prevalence and the risk factors of testosterone deficiency are similar between newly diagnosed and previously known type 2 diabetic men.

Abstract
Background This study investigated the association between statin use and herpes zoster (HZ) occurrence in a population-based case-control study. Methods Study subjects were retrieved from the Taiwan Longitudinal Health Insurance Database 2000. This study included 47,359 cases with HZ and 142,077 controls. We performed conditional logistic regression analyses to calculate the odds ratio (OR) to present the association between HZ and having previously been prescribed statin. Results We found that 13.0% of the sampled subjects had used statins, at 15.5% and 12.1% for cases and controls, respectively (p<0.001). A conditional logistic regression analysis suggested that the adjusted OR of being a statin user before the index date for cases was 1.28 (95% confidence interval (CI): 1.24∼1.32) compared to controls. Subjects aged 18∼44 years had the highest adjusted OR for prior statin use among cases compared to controls (OR: 1.69; 95% CI: 1.45∼1.92). Furthermore, we found that the ORs of being a regular and irregular statin user before the index date for cases were 1.32 (95% CI: 1.27∼1.38) and 1.23 (95% CI: 1.181.29), respectively, compared to controls. Conclusions We concluded that prior statin use was associated with HZ occurrence.
