Abstract
MicroRNAs (miRNAs) are small noncoding RNAs that regulate various diverse biological processes including insect spermatogenesis. The oriental fruit fly, Bactrocera dorsalis, is one of the most destructive horticultural pests in East Asia and the Pacific region. Although developmental miRNA profiles of B. dorsalis have enriched our knowledge, specific testicular miRNAs in this dipteran species are unexplored. In this study, we identified miRNAs from B. dorsalis testes by deep sequencing, which provided an overview of miRNA expression during spermatogenesis. Small RNA libraries were constructed from the testes of fully mature (FM), immature (IM) and middle-aged (MA) adult flies of B. dorsalis. Small RNA sequencing and data analysis revealed 172 known and 78 novel miRNAs amongst these libraries. Pairwise comparisons of libraries led to the identification of 24, 15 and 14 differentially expressed miRNAs in FM vs. IM, FM vs. MA and IM vs. MA insects, respectively. Using a bioinformatic approach, we predicted 124 target genes against the 13 most differentially expressed miRNAs. Furthermore, the expression patterns of six randomly selected miRNAs (from the 13 most differentially expressed miRNAs) and their putative target genes (from the 124 predicted target genes) were analysed in the testis of B. dorsalis by quantitative real-time PCR, which showed that out of six, four tested miRNAs-mRNAs had an inverse expression pattern and are probably co-regulated. This study is the first comparative profile of the miRNA transcriptome in three developmental stages of the testis, and provides a useful resource for further studies on the role of miRNAs in spermatogenesis in B. dorsalis.

Abstract
Mildronate is an agent for cardioprotection and neuroprotection. This study aimed to evaluate the pharmacokinetic (PK) profiles, safety and tolerability of mildronate injection after single escalating doses and multiple doses in healthy Chinese subjects. We performed a randomized, open-label, single- and multiple-dose phase I trial including 3 doses of mildronate: 250, 500 and 750 mg. Plasma and urine samples were collected and concentrations of mildronate were analyzed by liquid chromatography-mass spectrometry (LC-MS/MS). PK parameters were calculated using noncompartmental analysis. Safety and tolerability was assessed throughout noting subjects' vital signs and monitoring adverse events (AEs) and conduct a comprehensive physical examination and laboratory analyses before and after the study. There was no significant difference in C 0, AUC0-t, AUC0-∞ among 3 single-dose groups, whereas T 1/2 had significant statistical difference which may be caused by the inhibition of metabolic enzymes. Single- and multiple-dose intravenous injection of mildronate exhibited linear PK profiles in the range of 250-750 mg. An unconspicuous accumulation phenomenon was found after multiple-dose mildronate administration. No significant gender difference was found and mildronate is primarily excreted by the kidney. No serious AEs were observed. The formulation was safe and well tolerated from 250 to 750 mg.

Abstract
Resistance to nonsteroidal aromatase inhibitors is a major obstacle in the management of estrogen receptor-positive postmenopausal metastatic breast cancer. The addition of abiraterone acetate to exemestane did not improve clinical outcomes compared with exemestane alone in an androgen receptor-enriched population, potentially due to induced serum progesterone as a resistance mechanism. Background Androgen receptor (AR) signaling and incomplete inhibition of estrogen signaling may contribute to metastatic breast cancer (MBC) resistance to a nonsteroidal aromatase inhibitor (NSAI; letrozole or anastrozole). We assessed whether combined inhibition of androgen biosynthesis with abiraterone acetate plus prednisone and estradiol synthesis with exemestane (E) may be of clinical benefit to postmenopausal patients with NSAI-pretreated estrogen receptor-positive (ER+) MBC. Patients and methods Patients (N = 297) were stratified by the number of prior therapies for metastatic disease (0–1 versus 2) and by prior NSAI use (adjuvant versus metastatic), and randomized (1 : 1 : 1) to receive oral once daily 1000 mg abiraterone acetate plus 5 mg prednisone (AA) versus AA with 25 mg E (AAE) versus 25 mg E alone (E). Each treatment arm was well balanced with regard to the proportion of patients with AR-positive breast cancer. The primary end point was progression-free survival (PFS). Secondary end points included overall survival, clinical benefit rate, duration of response, and overall response rate. Results There was no significant difference in PFS with AA versus E (3.7 versus 3.7 months; hazard ratio [HR] = 1.1; 95% confidence interval [CI] 0.82–1.60; P = 0.437) or AAE versus E (4.5 versus 3.7 months; HR = 0.96; 95% CI 0.70–1.32; P = 0.794). Increased serum progesterone concentrations were observed in both arms receiving AA, but not with E. Grade 3 or 4 treatment-emergent adverse events associated with AA, including hypokalemia and hypertension, were less common in patients in the E (2.0% and 2.9%, respectively) and AA arms (3.4% and 1.1%, respectively) than in the AAE arm (5.8% for both). Conclusions Adding AA to E in NSAI-pretreated ER+ MBC patients did not improve PFS compared with treatment with E. An AA-induced progesterone increase may have contributed to this lack of clinical activity. ClinicalTrials.gov NCT01381874.

Abstract
PTEN serves as an intrinsic brake on neurite outgrowth, but the regulatory mechanism that governs its action is not clear. In the present study, miR-29a was found to increase neurite outgrowth by decreasing PTEN expression. Results showed that miR-92a-1, miR-29a, miR-92b, and miR-29c expression levels increased during nerve growth factor (NGF)-induced differentiation of PC12 cells. Based on in silico analysis of possible miR-29a targets, PTEN mRNA may be a binding site for miR-29a. A protein expression assay and luciferase reporter assay showed that miR-29a could directly target the 3'-UTRs (untranslated regions) of PTEN mRNA and down-regulate the expression of PTEN. PC12 cells infected with lentiviral pLKO-miR-29a showed far higher levels of miR-29a and Akt phosphorylation level than those infected with control. This promoted neurite outgrowth of PC12 cells. Collectively, these results indicate that miR-29a is an important regulator of neurite outgrowth via targeting PTEN and that it may be a promising therapeutic target for neural disease.

Abstract
OBJECTIVES To examine the associations between consultations with complementary and alternative medicine (CAM) practitioners and menopause-related symptoms. METHODS A cross-sectional survey of a nationally representative sample of 10 011 women aged 59-64 years from the Australian Longitudinal Study on Women's Health, conducted in 2010. Women, including those with hysterectomy, oophorectomy and natural menopause, were asked about their consultations with a range of CAM practitioners and menopause-related symptoms experienced. RESULTS Acupuncturists were more likely to be consulted by women with hysterectomy experiencing night sweats (odds ratio, OR = 2.21), but were less likely to be consulted by those experiencing hot flushes (OR = 0.53). Acupuncturists were also more likely to be consulted by women with oophorectomy (OR = 3.11) and natural menopausal women (OR = 1.57) experiencing back pain. Massage therapists were more likely to be consulted by women with oophorectomy experiencing back pain (OR = 1.98), women with hysterectomy experiencing anxiety (OR = 1.52), and natural menopausal women experiencing back pain (OR = 1.54) and/or anxiety (OR = 1.29). Naturopaths/herbalists were more likely to be consulted by women with oophorectomy experiencing leaking urine (OR = 2.08). Chiropractors/osteopaths were more likely to be consulted by women across all menopausal status experiencing back pain (OR = 2.52, 2.31 and 2.25 for women with oophorectomy, hysterectomy and natural menopause, respectively). CONCLUSIONS There are substantial levels of CAM practitioners' consultations amongst menopausal women, with a range of menopause-related symptoms associated with the use of specific CAM practitioner modalities. It is important that health-care providers are mindful of CAM practitioner use in order to ensure safe, effective and coordinated treatment and support for menopausal women in their care.

Abstract
OBJECTIVE Several biomarkers, including maternal serum creatinine kinase and α-fetoprotein, have been described as potential tools for the diagnosis of placental abnormalities. This study aimed to determine whether maternal plasma mRNA levels of the β subunit of human chorionic gonadotropin (β-HCG) could predict placenta accreta prenatally. METHODS Sixty-eight singleton pregnant women with prior cesarean deliveries (CDs) were classified into three groups: normal placentation (35 women, control group); placenta previa alone (21 women, placenta previa group); and both placenta previa and placenta accreta (12 women, placenta previa/accreta group). Maternal plasma concentrations of cell-free β-HCG mRNA were measured by real-time reverse-transcription polymerase chain reaction and were expressed as multiples of the median (MoM). RESULTS Cell-free β-HCG mRNA concentrations (MoM, range) were significantly higher in women with placenta accreta (3.65, 2.78-7.19) than in women with placenta previa (0.94, 0.00-2.97) or normal placentation (1.00, 0.00-2.69) (Steel-Dwass test, P < 0.01 and P < 0.01, respectively). In the placenta previa/accreta group, the concentration of cell-free β-HCG mRNA was significantly higher among women who underwent CDs with hysterectomy (4.41, 3.49-7.19) than among women whose CDs did not result in hysterectomy (3.20, 2.78-3.70) (Mann-Whitney U test, P = 0.012). DISCUSSION An increased level of cell-free β-HCG mRNA in the maternal plasma of women with placenta accreta may arise from direct uteroplacental transfer of cell-free placental mRNA molecules. CONCLUSIONS The concentration of cell-free β-HCG mRNA in maternal plasma may be applicable to the prenatal diagnosis of placenta accreta, especially to identify women with placenta accreta likely to require hysterectomy.

Abstract
OBJECTIVES To provide the first critical review of traditional Chinese medicine (TCM) use amongst symptomatic menopausal women, drawing upon work examining the perspectives of both TCM users and TCM practitioners. METHODS A search was conducted in three English-language databases (MEDLINE, CINAHL and AMED) and three Chinese-language databases (CNKI, VIP and CBM Disc) for 2002-2013 international peer-reviewed articles reporting empirical findings of TCM use in menopause. RESULTS A total of 25 journal articles reporting 22 studies were identified as meeting the review inclusion criteria. Chinese herbal medicine appears to be the most common therapy amongst symptomatic menopausal women, and vasomotor symptoms and emotional changes are the most frequent symptoms for which TCM is sought. However, evidence regarding the prevalence of TCM use and users' profile in menopause is limited. Existing studies are of varied methodological quality, often reporting low response rate, extensive recall bias and a lack of syndrome differentiation. CONCLUSIONS This review provides insights for practitioners and health policy-makers regarding TCM care to symptomatic menopausal women. More nationally representative studies are required to rigorously examine TCM use for the management of menopausal symptoms. Syndrome differentiation of menopausal women is an area which also warrants further attention.

Abstract
Background: We analyzed the potential of abiraterone acetate (henceforth abiraterone) to reduce androgen levels below lower limits of quantification (LLOQ) and explored the association with changes in PSA decline in metastatic castration-resistant prostate cancer (mCRPC) patients. Methods: COU-AA-301 is a 2:1 randomized, double-blind, placebo-controlled study comparing abiraterone (1000 mg q.d.) plus low-dose prednisone (5 mg b.i.d.) with placebo plus prednisone in mCRPC patients post docetaxel. Serum testosterone, androstenedione and dehydroepiandrosterone sulfate from baseline to week 12 were measured by novel ultrasensitive two-dimensional liquid chromatography coupled to tandem mass spectrometry assays in a subset of subjects in each arm (abiraterone plus prednisone, n=80; prednisone, n=38). The association between PSA response (⩽50% baseline) and undetectable androgens (week 12 androgen level below LLOQ) was analyzed using logistic regression. Results: A significantly greater reduction in serum androgens was observed with abiraterone plus prednisone versus prednisone (all P⩽0.0003), reaching undetectable levels for testosterone (47.2% versus 0%, respectively). A positive association was observed between achieving undetectable serum androgens and PSA decline (testosterone: odds ratio=1.54; 95% confidence interval: 0.546–4.347). Reduction of androgens to undetectable levels did not occur in all patients achieving a PSA response, and a PSA response did not occur in all patients achieving undetectable androgen levels. Conclusions: Abiraterone plus prednisone significantly reduced serum androgens, as measured by ultrasensitive assays and was generally associated with PSA response. However, androgen decline did not uniformly predict PSA decline suggesting ligand-independent or other mechanisms for mCRPC progression.

Abstract
BACKGROUND The clinical symptoms of NK/T-cell lymphoma at presentation are nonspecific and may mimic those of other benign nasal diseases such as rhinitis and nasal polypus. However, radiologic studies regarding this aggressive clinical course entity are limited. AIM To review 123 newly diagnosed MRI appearances in patients with extra-nodal NK/T-cell lymphoma, nasal type, in a large cohort and determine the characteristic imaging findings. SUBJECTS AND METHODS We investigated the magnetic resonance imaging (MRI) findings of patients with newly diagnosed stage IE/IIE extranodal NK/T-cell lymphoma, nasal type, in the upper aerodigestive tract. RESULTS Most nasal cavity patients (63.4%) showed extra nasal cavity involvements. The polypoid pattern was most frequently seen (55.3%), followed by the infiltrative (27.6%) and combined (17.1%) patterns. The polypoid pattern tended to develop in the nasal cavity group, while the infiltration pattern was more common in the non-nasal cavity group (63.4% vs. 60.0%, p < 0.001). Homogeneous iso-intensity was seen in 97.6%, 88.6% and 56.1% of cases on T1-, T2-weighted images and post-contrast images, respectively. Bone destruction and necrosis were observed in 44.7% and 56.3% of patients. Both tumour necrosis and bone destruction were related to tumour size (p = 0.008, 0.001). Only 12.2% of patients had cervical lymphadenopathy Multi-region involvement, irregular growth pattern, predisposition to necrosis and bone destruction, and little lymphadenopathy are valuable for diagnosis and can be used to differentiate these tumours from other malignant tumours. CONCLUSIONS Our large cohort study of MRI of NK/T cell lymphoma, nasal type, revealed the features of this lymphoma on MRI including some radiologic signs never reported earlier; these findings are invaluable for early diagnosis and may aid future studies aiming to predict the prognosis and response to therapy.
