Abstract
OBJECTIVES Complementary and alternative medicine (CAM) is increasingly used by those suffering from constipation. This paper reports the first critical integrative review of CAM use for people with constipation focusing upon the prevalence, type and cost of CAM use, as well as CAM users' profile, perception and motivations. METHODS A comprehensive search of international literature was conducted in MEDLINE, Academic Search Complete (EBSCO), and Allied and Complementary Medicine Database (AMED). The search was limited to original research peer-reviewed English language articles concerning CAM use for constipation published with an abstract and full text between 2005 and 2015. RESULTS A total of 35 papers met the inclusion criteria and were included in the review. The review shows approximately one in every three people suffering from constipation use CAM with herbal medicine the most commonly used CAM treatment for constipation and a large proportion of CAM use occurring concurrent with or in addition to conventional medical treatments. While early investigation suggests the cost of herbal medicine use in constipation care may be lower than that associated with the use other CAM modalities and conventional medications, this issue requires further research. CONCLUSIONS Although a high percentage of people with constipation using CAM consider these treatments effective, there remains a need for further in-depth examination of both patient and provider perspectives as well as communication and decision-making around CAM use for constipation to inform safe, effective and coordinated care for patients with constipation.

Abstract
Urinary vascular endothelial growth factor (VEGF) was determined by enzyme-linked immunosorbent assay in 199 renal allograft recipients and 80 healthy controls. Urinary VEGF level did not change significantly during the first 8 weeks after transplantation in 119 patients with stable renal function and there were no abnormal histological findings (No-AR). In 67 patients with acute rejection, urinary VEGF was significantly higher (28.57 ± 6.21 pg/μmol creatinine) than in the No-AR patients (3.05 ± 0.45 pg/μmol creatinine) and healthy controls (2.87 ± 0.35 pg/μmol creatinine). At a cut-off point of 3.26 pg/μmol creatinine, sensitivity and specificity for diagnosis of acute rejection were 86.6 and 71.4%, respectively. The 13 patients with subclinical rejection excreted urinary VEGF (16.14 ± 4.09 pg/μmol creatinine) at a significantly higher level than No-AR patients (3.05 ± 0.45 pg/μmol creatinine). At a cut-off point of 4.69 pg/μmol creatinine, sensitivity and specificity for diagnosis of subclinical rejection were 84.6 and 79.8%, respectively. In conclusion, monitoring VEGF in urine might offer a new non-invasive way to detect acute and subclinical rejection in renal transplant recipients.

Abstract
AIM Endoplasmic reticulum (ER) stress in the brain subfornical organ (SFO), a key cardiovascular regulatory centre, has been implicated in angiotensin (ANG) II-induced hypertension in males; however, the contribution of ER stress to ANG II-induced hypertension in females is unknown. Female hormones have been shown to prevent ER stress in the periphery. We tested the hypothesis that females are less susceptible to ANG II-induced SFO ER stress than males, leading to sex differences in hypertension. METHODS Male, intact and ovariectomized (OVX) female rats received a continuous 2-week subcutaneous infusion of ANG II or saline. Additional male, intact and OVX female rats received intracerebroventricular (ICV) injection of ER stress inducer tunicamycin. RESULTS ANG II, but not saline, increased blood pressure (BP) in both males and females, but intact females exhibited smaller increase in BP and less depressor response to ganglionic blockade compared with males or OVX females. Molecular studies revealed that ANG II elevated expression of ER stress biomarkers and Fra-like activity in the SFO in both males and females; however, elevations in these parameters were less in intact females than in males or OVX females. Moreover, ICV tunicamycin induced smaller elevation in BP and less increase in expression of ER stress biomarkers in the SFO in intact females compared with males or OVX females. CONCLUSION The results suggest that differences in ANG II-induced brain ER stress between males and females contribute to sex differences in ANG II-mediated hypertension and that oestrogen protects females against ANG II-induced brain ER stress.

Abstract
This paper presents an integrated system for the automatic analysis of mammograms to assist radiologists in confirming their diagnosis in mammography screening. The proposed automated confirmatory system (ACS) can process a digitalized mammogram online, and generates a high quality filtered segmentation of an image for biological interpretation and a texture-feature based diagnosis. We use a serial of image pre-processing and segmentation techniques, including 2D median filtering, seeded region growing (SRG) algorithm, image contrast enhancement, to remove noise, delete radiopaque artifacts and eliminate the projection of the pectoral muscle from a digitalized mammogram. We also develop an entire-image texture-feature based classification method, by combining a Rough-set approach to extract five fundamental texture features from images, and then an Artificial Neural Network technique to classify a mammogram as: normal; indicating the presence of a benign lump; or representing a malignant tumor. Here, 222 random images from the Mammographic Image Analysis Society (MIAS) database are used for the offline ACS training. Once the system is tuned and trained, it is ready for the automated use for the analysis and diagnosis of new mammograms. To test the trained system, a separate set of 100 random images from the MIAS and another set of 100 random images from the independent BancoWeb database are selected. The proposed ACS is shown to be successful in confirming diagnosis of mammograms from the two independent databases.

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.
