Objective. To systematically evaluate the efficacy and safety of Dan'e-fukang soft extract in endometriosis treatment. Method. PubMed, CNKI, Wanfang Database, VIP, SinoMed, and Cochrane Library were searched. Randomized controlled trials (RCTs) comparing the efficacy of Dan'e-fukang soft extract and conventional western medicines for endometriosis treatment were included. The data were extracted independently by two people and analyzed using RevMan 5.2.0 software. The relative risk (RR) and mean difference (MD) with 95% confidence intervals were considered as effective outcome indicators. Results. Thirty-nine papers including 5442 patients with endometriosis were included in this study. A meta-analysis revealed that Dan'e-fukang soft extract was more efficient than gestrinone in the treatment of endometriosis (RR = 1.08, 95% CI = 1.03 to 1.15, I2 = 71%, REM, 18 trials) and its efficacy was comparable to that of danazol and mifepristone. Dan'e-fukang soft extract was also as effective as gestrinone and mifepristone in terms of relapse rate and relieving dysmenorrhea. The incidence of adverse reactions was lower than that of conventional western medicines. Conclusions. The results of this study showed that Dan'e-fukang soft extract offers certain advantages in endometriosis treatment, but rigorously designed, strictly implemented RCTs are needed to further validate its efficacy. © 2017 Yantao Li et al.

Endometriosis is a complex disease that affects a large number of women worldwide and may cause pain and infertility. To systematically review published studies evaluating the relationship between menstrual cycle length and risk of endometriosis. We searched the Cochrane Library, PubMed, Web of Science, and EMBASE in databases in July 2014 using the keywords "case-control studies," "epidemiologic determinants," "risk factors," "menstrual cycle," "menstrual length," "menstrual character," and "endometriosis." We included case-control studies published in English that investigated cases of surgically confirmed endometriosis and examined the relationship between endometriosis risk and menstrual cycle. Eleven articles that met the inclusion criteria included data of 3392 women with endometriosis and 5006 controls. Fixed-effects and random-effects models were used for the evaluation. For the association of risk of endometriosis and menstrual cycle length shorter than or equal to 27 days (SEQ27) or length longer than or equal to 29 days (LEQ29), the odds ratio was 1.22 (95% confidence interval [CI]: 1.05-1.43) and 0.68 (95% CI: 0.48-0.96), respectively. In conclusion, this meta-analysis suggests that menstrual cycle length SEQ27 increase the risk of endometriosis and cycle length LEQ29 decrease the risk. Copyright © 2016 Wolters Kluwer Health, Inc.

The scarcity of tissue-specific stem cells and the complexity of their surrounding environment have made molecular characterization of these cells particularly challenging. Through single-cell transcriptome and weighted gene co-expression network analysis (WGCNA), we uncovered molecular properties of CD133+/GFAP- ependymal (E) cells in the adult mouse forebrain neurogenic zone. Surprisingly, prominent hub genes of the gene network unique to ependymal CD133+/GFAP- quiescent cells were enriched for immune-responsive genes, as well as genes encoding receptors for angiogenic factors. Administration of vascular endothelial growth factor (VEGF) activated CD133+ ependymal neural stem cells (NSCs), lining not only the lateral but also the fourth ventricles and, together with basic fibroblast growth factor (bFGF), elicited subsequent neural lineage differentiation and migration. This study revealed the existence of dormant ependymal NSCs throughout the ventricular surface of the CNS, as well as signals abundant after injury for their activation. © 2015 Elsevier Inc.

Autophagy is the main catabolic pathway in cells for the degradation of impaired proteins and organelles. Accumulating evidence supports the hypothesis that dysfunction of autophagy, leading to an imbalance of proteostasis and the accumulation of toxic proteins in neurons, is a central player in the pathogenesis of neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS). The clinical pathology of ALS is complex and many genes associated with autophagy and RNA processing are mutated in patients with the familial form. But a causal relationship between autophagic dysfunction and ALS has not been fully established. More importantly, studies on the pathological mechanism of ALS are mainly based on animal models that may not precisely recapitulate the disease itself in human beings. The development of human iPSC techniques allows us to address these issues directly in human cell models that may profoundly influence drug discovery for ALS. © 2015, Shanghai Institutes for Biological Sciences, CAS and Springer-Verlag Berlin Heidelberg.

Ligustrazine is a principal ingredient of chuanxiong. Concerns regarding the evaluation of the effectiveness of ligustrazine in the treatment of UA have resulted in a meta-analysis combined with recent clinical evidence. Seven computer databases that included the China hospital knowledge database (CHKD), Wanfang Med Online, the Chinese medical journal database (CMJD), PubMed, Cochrane, Embase (Ovid), and Medline (Ovid) were systematically searched. We included randomized controlled trials and quasi-randomized controlled trials. Our systematic review identified 16 RCTs that met our eligibility criteria. Ligustrazine combined with conventional medicine was associated with an increased rate of marked improvement in symptoms and an increased rate of marked improvement of ECG compared with conventional Western medicine alone. Additionally, the use of ligustrazine was associated with significant trends in the reduction of the consumption of nitroglycerin and the level of fibrinogen when compared with conventional Western medicine alone. No firm results were found between the intervention and the control method groups in the reduction of the time of onset or the frequency of acute attack angina due to the high level of heterogeneity. In conclusion, our meta-analysis found that ligustrazine was associated with some benefits for people with unstable angina. © 2016 Suman Cao et al.

Trials | Year: 2016

Background: Practitioners of traditional Chinese medicine know that auricular point acupressure (APP) using vaccaria seeds on the large intestine point (CO7) has a significant effect on postoperative gastrointestinal dysfunction. A standardized, clinical, research design will transform this clinical experience into scientific evidence, thus providing a basis to promote the wider use of this therapy. We aim to carry out a double-blind, randomized, controlled trial (RCT) to evaluate the efficacy and safety of APP treatment for gastrointestinal dysfunction after laparoscopic cholecystectomy. Methods/design: This study is a randomized, double-blind, controlled, single-center, clinical, pilot trial. It has been designed according to the Consolidated Standards of Reporting Trials (CONSORT 2010) guidelines as well as the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). Study subjects are being selected from among hospitalized patients who have undergone laparoscopic cholecystectomy at the Department of Minimally Invasive Surgery of Tianjin Nankai Hospital. Qualified subjects will be assigned randomly either to the APP group or to the APP sham stimulation group on the basis of random numbers generated using SPSS 19.0. A specifically appointed investigator will be responsible for the randomization. The APP therapy (or sham stimulation) will be performed 6 h after surgery and every 12 h subsequently; six sessions will be conducted, each lasting 3 min. The first evaluation will be performed immediately before the first treatment (6 h after surgery) and, then, every 12 h for seven evaluations. The primary outcome is the time to first passage of flatus after surgery; the secondary outcome measures are abdominal distension, nausea, vomiting, time to first defecation, psychological status, and quality of life. Discussion: This pilot trial is a standardized, scientific, clinical trial designed to evaluate the efficacy and safety of APP treatment-using vaccaria seeds on CO7-for gastrointestinal dysfunction after laparoscopic cholecystectomy. We aim to provide objective evidence to promote this therapy in clinical practice. Trial registration: Chinese Clinical Trial Registry, ChiCTR-IPR-15007643.

Background: Endometriosis has many hypothesized etiologies. Known risk factors include genetic predisposition, uterine outflow abnormalities, and iatrogenic causes. Of increasing concern is prenatal environmental exposures. However, the findings of studies investigating the relationships between prenatal environmental exposures and the development of endometriosis have not always been conclusive, and therefore, the relationships are debatable. Methods: This review presents a summary and analysis of the current studies that investigated the effects of prenatal environmental exposures on the development of endometriosis in female offspring. Results: Prenatal exposure to estrogenic substances (such as ethinyl estradiol and diethylstilbestrol) and environmental toxins (such as 2,3,7,8-tetrachlorodibenzo-p-dioxin, polychlorinated biphenyls, and bisphenol A) may increase the incidence of endometriosis in female offspring. However, exposure to cigarette smoke may protect against the development of endometriosis in female offspring mainly because of its antiestrogenic effects. Conclusion: Certain prenatal environmental exposures might result in the development of endometriosis in female offspring. In addition to known environmental exposures that predispose the development of endometriosis in adulthood, such as dioxin and radiation exposure (animal models), prenatal exposures are of increasing concern. © The Author(s) 2016.
