Interaction effects of asthma and rhinitis control on work productivity and activity impairment: A cross-sectional study.

Background: Symptomatic asthma and rhinitis negatively impact patients' work productivity and activity. However, little is known about the potential interaction effect of both asthma and rhinitis control on work productivity and activity impairment. Objective: This study aimed to explore whether there are interaction effects of asthma and rhinitis control on work productivity and activity impairment in patients with asthma and with rhinitis. Methods: A total of 206 adult patients were prospectively recruited and were divided into four groups: both poorly controlled (BPC) n = 53), poorly controlled asthma (PCA) with controlled rhinitis (CR) (n = 38), well controlled asthma with uncontrolled rhinitis (n = 43), and both well controlled (BWC) (n = 72) based on the symptom control status of asthma and rhinitis. Work productivity loss and activity impairment, asthma control, and rhinitis control were assessed by using work productivity and activity impairment questionnaire: general health, the asthma control test, and the rhinitis control assessment test, respectively. General linear regression models were used to study the contribution of asthma control, rhinitis control, and the interaction effect on work productivity and activity impairment. Results: Work productivity loss was most frequently reported in patients in the BPC group. Compared with the patients in the BWC group, the patients in the PCA-CR group had significantly higher activity impairment and worse asthma-related quality of life (both p < 0.001). There were significant interaction effects of asthma and rhinitis control, which accounted for the increase in presenteeism, work productivity loss, and activity impairment (all p < 0.001). Although differences in absenteeism were not significant among the groups, there was a significant interaction effect of control levels accounted for absenteeism (p = 0.035). Conclusion: Distinct interaction effects of asthma and rhinitis control reflected a link between upper and lower airways, which indicated that rhinitis control and the interaction effects of asthma and rhinitis control cannot be neglected during asthma management.

Depressive symptom-associated IL-1ß and TNF-α release correlates with impaired bronchodilator response and neutrophilic airway inflammation in asthma.

BACKGROUND: Depressive symptoms worsen asthma outcomes; however, the mechanism remains largely unexplored. OBJECTIVE: This study aimed to determine whether depressive symptom-associated immune inflammation correlates with impaired bronchodilator response (BDR) and airway inflammatory phenotypes. METHODS: Eligible adults with asthma (n = 198) underwent clinical assessment, sputum induction and blood sampling. Depressive symptoms were defined by scores on the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). Pre- and post-bronchodilator spirometry was performed for BDR. Airway inflammatory phenotypes were defined by sputum cell counts. CRP, IL-1ß, IL-5, IL-6, IL-8, TNF-α, IFN-γ, CCL17 and CCL22 in serum and sputum were detected. RESULTS: Compared with the non-depressive group (n = 174), the depressive group (n = 24) exhibited impaired BDR (P = 0.032) and increased sputum neutrophils (P = 0.023), which correlated with the HADS-D scores (P = 0.027 and P = 0.029). Levels of IL-1ß, TNF-α and IFN-γ in the serum and those of IL-1ß and IFN-γ in the sputum were elevated in the depressive group compared to those in the non-depressive group (all P < 0.05). Multiple regression models indicated that TNF-α in the sputum and IL-1ß, IL-6 and IFN-γ in both the serum and sputum were inversely associated with BDR; TNF-α in the sputum and IL-1ß in both the serum and sputum were positively correlated with sputum neutrophils. Mediation analyses revealed that IL-1ß and TNF-α in the sputum and IL-1ß in both the serum and sputum mediate the correlations of the HADS-D scores with BDR and sputum neutrophils, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: Asthma patients with depressive symptoms present worse asthma control, which is most likely explained by impaired BDR and neutrophilic airway inflammation. IL-1ß and TNF-α, which are two key pro-inflammatory cytokines that mediate the correlation of depressive symptoms with impaired BDR and neutrophilic airway inflammation, may serve as targeted biomarkers in the neuropsychological phenotype of asthma; however, this result needs to be further validated.

Systemic inflammation mediates the detrimental effects of obesity on asthma control.

BACKGROUND: Obesity negatively impacts asthma control, but the inflammatory mechanisms are poorly understood. OBJECTIVE: To explore which systemic inflammatory mediators mediate the effects of obesity on asthma control. METHODS: The subjects with stable asthma (n = 108) underwent assessment of clinical characteristics, which included using The Asthma Control Questionnaire (ACQ)-6. Obesity was defined as a body mass index (BMI) of ≥30 kg/m2, overweight was defined as BMI between 25 to 29.9 kg/m2, and lean weight was defined as BMI < 25 kg/m2. Body composition, including fat mass (FM), visceral fat area (VFA), and percentage body fat (PBF) was analyzed by bioimpedance. Serum interleukin (IL) 4, IL-5, IL-8, IL-13, IL-17, chemokine (C-C motif) ligand (CCL) 17, CCL22, leptin, adiponectin, C-reactive protein (CRP), and interferon (IFN) gamma were measured by using ELISA. Linear regression models were fitted according to the Baron and Kenny procedures for mediation analysis. RESULTS: FM (12.73 ± 3.95 versus 18.59 ± 2.95 versus 27.82 ± 5.17 kg; p < 0.0001), VFA (65.99 ± 23.17 versus 93.96 ± 10.28 versus 123.10 ± 18.34 cm2; p < 0.0001), PBF (23.86 ± 7.46 versus 30.74 ± 5.08 versus 36.21 ± 6.28 %; p = 0.0003) and ACQ-6 values (0.83 [0, 1.17]) versus 1.15 [0.50, 1.75] versus 1.33 [0.83, 1.83] score; p = 0.002) were different among lean (n = 52), overweight (n = 37), and obese (n = 19) subjects. Serum levels of leptin, IL-5, IL-13, IL-17, CCL17, CRP, and IFN-gamma in the obese group were significantly elevated compared with the subjects who were lean or overweight (all p < 0.05). The mediation analyses found that the effect of obesity, assessed by BMI, on ACQ-6 was significantly mediated through IL-13 and CCL17. Furthermore, IL-13 and CCL17 mediated the effects of body composition (FM, VFA and PBF) on ACQ-6. The effects of obesity assessed by body composition, but not by using BMI, on ACQ-6 were mediated by leptin. CONCLUSION: Our mediation analysis confirmed that systemic inflammation biomarkers, such as leptin, CCL17, IL-4, and IL-13, mediated the effects of obesity on asthma control. This warrants prospective exploration in this distinct asthma phenotype in the future.

Corticosteroid plus ß2-agonist in a single inhaler as reliever therapy in intermittent and mild asthma: a proof-of-concept systematic review and meta-analysis.

BACKGROUND: Current guidelines recommend a single inhaler maintenance and reliever therapy (SMART) regimen for moderate to severe asthma. However, evidence for the inhaled corticosteroid plus fast-onset-acting ß2-agonist (ICS/FABA) as reliever therapy in management of intermittent and mild asthma patients is lacking. OBJECTIVE: To systematically explore efficacy and safety of the proof-of-concept of the ICS plus FABA regimen in a single inhaler as reliever therapy across children and adults with intermittent and mild persistent asthma. METHODS: We searched online bibliographic databases for randomized controlled trials (RCTs) involving the as-needed use of ICS/FABA as monotherapy in intermittent or mild asthma patients. The primary outcomes were exacerbations and the hazard ratio (HR) of the time to first exacerbation. RESULTS: Six RCTs (n = 1300) met the inclusion criteria. Compared with the as-needed FABA regimen, the as-needed use of ICS/FABA as monotherapy statistically reduced exacerbations (RR = 0.56, P = 0.001). Compared with regular ICS regimen, the as-needed ICS/FABA therapy had slightly higher risk of exacerbations (RR = 1.39, P = 0.011). The HR for time to first exacerbations in the ICS/FABA regimen was significant lower when compared with FABA regimen (HR = 0.52, P = 0.002) but had no difference when compared with ICS regimen (HR = 1.30, P = 0.286). The corticosteroid exposure in the daily ICS regimen was 2- to 5-fold compared with as-needed use of ICS/FABA regimen. CONCLUSIONS: Our analysis shows that the ICS/FABA as a symptom-driven therapy may be a promising alternative regimen for the patients with intermittent or mild asthma, but it needs further real-world RCTs to confirm these findings.

Prevalence of sexual dysfunction in men with chronic prostatitis/chronic pelvic pain syndrome: a meta-analysis.

PURPOSE: This study aims to estimate the prevalence of sexual dysfunction in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) by conducting a meta-analysis. METHODS: Relevant publications were searched using PubMed, Embase, CBM, China National Knowledge Infrastructure, VIP and Wanfang databases up to August 2015. Studies that reported the prevalence of erectile dysfunction, premature ejaculation and total sexual dysfunction in men with CP/CPPS were included. RESULTS: A total of 24 studies involving 11,189 men were included. Overall prevalence of sexual dysfunction in men with CP/CPPS was 0.62 (95 % CI 0.48-0.75), while the prevalence of erectile dysfunction and premature ejaculation was 0.29 (95 % CI 0.24-0.33) and 0.40 (95 % CI 0.30-0.50), respectively. From 1999 to 2010, the prevalence of sexual dysfunction, erectile dysfunction and premature ejaculation was 0.65 (95 % CI 0.45-0.83), 0.27 (95 % CI 0.22-0.33) and 0.41 (95 % CI 0.27-0.55), respectively. From 2011 to 2014, the prevalence of sexual dysfunction, erectile dysfunction and premature ejaculation was 0.50 (95 % CI 0.22-0.75), 0.35 (95 % CI 0.29- 0.40) and 0.39 (95 % CI 0.37-0.41), respectively. CONCLUSION: The prevalence of sexual dysfunction in men with CP/CPPS was high, even though overall sexual dysfunction demonstrated a slightly decreasing trend. Furthermore, erectile dysfunction prevalence rate had an increasing trend in recent years. More prospective studies are needed to evaluate sexual dysfunction improvement with better management of CP/CPPS.

Effectiveness and safety of ShenXiong glucose injection for acute ischemic stroke: a systematic review and GRADE approach.

BACKGROUND: To appraise critically whether published trials of ShenXiong glucose injection for patients with acute ischemic stroke (AIS) are of sufficient quality, and in addition to rate the quality of evidence by using the GRADE approach (grading of recommendations, assessment, development, and evaluation, GRADE). METHODS: A literature search was performed in the Cochrane Library, MEDLINE, EMBASE, CBM, Chinese TCM (traditional Chinese medicine) Database, CNKI, VIP, WanFang Databases until January 2015. The limits were patients with AIS and randomized controlled trials (RCTs) or quasi-RCTs. Studies by which patients suffering intracerebral haemorrhage were excluded. RESULTS: Twelve studies fulfilled the inclusion criteria. We found significant benefits of ShenXiong glucose injection compared with conventional treatment in improving activities of daily living function at 4 weeks (MD = 34.12, 95 % CI: 29.07, 39.17), neurological function deficit at 2 weeks (MD = -5.39, 95% CI: -6.90, -3.87), 4 weeks (MD = -5.16, 95 % CI: -6.49, -3.83), and clinical effects at 4 weeks (RR = 1.17, 95% CI: 1.10, 1.24). No trials reported the effects of ShenXiong glucose injection on the risk of early, deterioration, or quality of life. No adverse events were reported within the whole follow-up period. CONCLUSIONS: The use of ShenXiong glucose injection may improve rehabilitation for patients with acute ischemic stroke, however, as the GRADE approach indicated low to moderate quality of available evidence as well as insufficient information about harm and patients preference, the recommendations were not provided for ShenXiong glucose injection taking as a therapeutic intervention to patients with acute ischemic stroke.

Age-Related Clinical Characteristics, Inflammatory Features, Phenotypes, and Treatment Response in Asthma.

BACKGROUND: Emerging evidence suggests that aging affects asthma outcomes, but the mechanism remains largely unexplored. OBJECTIVE: To explore age-related clinical characteristics, inflammatory features, phenotypes, and treatment response in asthma. METHODS: This was a prospective cohort study of asthmatic patients with a 12-month follow-up in a real-world setting. Clinical inflammatory and phenotypic characteristics, future risk for exacerbations, and treatment response were assessed across different age groups (young was defined as age 18 to 39 years; middle-aged, 40 to 64 years; and elderly, 65 years or older). RESULTS: Compared with young (n = 106) and middle-aged (n = 179) asthmatic patients, elderly patients (n = 55) had worse airway obstruction, more comorbidities including chronic obstructive pulmonary disease and diabetes, less atopy, and lower levels of IgE and FeNO, and were more likely to have late-onset and fixed airflow obstruction asthma and a reduced risk for having type 2 profile asthma. Levels of IFN-gamma, IL-17A, and IL-8 in induced sputum were significantly increased in elderly asthmatic patients (all P < .05). Path analysis indicated that age directly and significantly led to future exacerbations in asthma, partially mediated by an upregulation of airway IFN-gamma. Moreover, elderly patients with asthma had a reduced treatment response (improvement in FEV1 of 12% or greater, or 200 mL, and a reduction in Borg scores of 1 or greater) (adjusted odds ratio = 0.11; 95% CI, 0.02-0.52; and adjusted odds ratio = 0.12; 95% CI, 0.03-0.49, respectively). CONCLUSIONS: This study confirms that asthma in the elderly population represents a specific phenotype and indicates that aging can influence asthma in terms of clinical characteristics, inflammatory features, exacerbations, and treatment response.

[Methodological quality assessment of systematic reviews correlated to traditional Chinese medicine published in China].

OBJECTIVE: To assess the methodological quality of systematic reviews or Meta-analysis of traditional Chinese medicine published in China, and to validate the applicability of OQAQ (Overview Quality Assessment Questionnaire) and AMSTAR (a measurement tool to assess systematic reviews) in traditional Chinese medicine (Chinese Medical). METHODS: Comprehensive literature retrieve was performed in CBM, CNKI, VIP as well as hand searching in Chinese Journal of Evidence-Based Medicine. The retrieve was started from January 1, 1999 and terminated by December 2008. The methodological quality of traditional Chinese medicine correlated systematic reviews was evaluated using OQAQ and AMSTAR simultaneously. RESULTS: A total of 115 systematic reviews involved 17 types of diseases, of which, the cardio-/cerebrovascular diseases was dominant (36 papers, 31.30%). The mean OQAQ score was 2.50 (95% CI: 2.22, 2.76). No significant correlation was found in OQAQ score with publication year (P = 0.35) and different disease types (P = 0.28). High consistency was observed in evaluations of systematic reviews by using OQAQ and AMSTAR (both Kappa values > 0.75). Compared with the OQAQ, AMSTAR incorporated 3 additional items: the topics, publication bias, and conflict of interest, etc. Although 98.26% of systematic reviews proposed protocols in prior, 53.04% failed to analyze the publication bias. Besides, 57.39% neglected to address the potential conflict of interest. CONCLUSIONS: Poor methodological quality in systematic reviews of Chinese Medical published in China needs to be improved and emphasized. It is necessary to integrate the special characteristics of traditional Chinese medicine itself when choosing topics of systematic reviews. It is essential to establish quality assessment tools targeting systematic reviews of traditional Chinese medicine.

[The protein expression of ERCC1 and survivin in epithelial ovarian carcinoma and their clinical significance].

OBJECTIVE: To investigate the protein expression of ERCC1 (excision repair cross complementation group 1) and survivin gene in platinum-resistant and platinum-sensitive epithelial ovarian carcinoma (EOC), and to explore the relationship among ERCC1 expression, survivin expression, the major clinicopathological characteristics as well as platinum sensitivity. METHODS: Expression of ERCC1 and survivin were detected in 64 EOC tissues by immunohistochemical method. RESULTS: No significant differences were found in patients' age, FIGO stage, pathological type, histological grade, pelvic lymph node and/or vessel infiltration, in all of three pairs of comparison. They were platinum-sensitive group vs. platinum-resistant group, ERCC1-positive group vs. ERCC1-negative group and surviving-positive group vs. survivn-negative group (all P > 0.05). The positive rate of ERCC1 expression (67.85%, 19/28) in platinum-resistant patients' tissues was significantly higher than that in platinum-sensitive patients' tissues (25.00%, 9/36) (P = 0.001). While the positive rate of survivin in platinum-resistant patients' tissues (78.57%, 22/28) was slightly higher than that of in platinum-sensitive patients' tissues (75.00%, 29/36), however without significant (P = 0.74). No evidence was found that the expression of ERCC1 correlate with the expression of survivin (r(s) = 0.12, P = 0.36) too. The proportion of platinum-resistant in patients with coexpression of ERCC1 and surviving (65.22%, 15/23) was insignificantly lower than that of in patients with single expression of ERCC1 (80.00%, 4/5) (P = 0.91). CONCLUSION: Expression of ERCC1 in EOC patients' tumor tissue could be a predictive indicator for their platinum susceptibility and it might be helpful for prevention and reverse of platinum resistance in clinical practice. The expression of survivin seems of no definite value in prediction of platinum susceptibility.

[Developing a risk appraisal model for gestational diabetes mellitus].

OBJECTIVE: To identify risk factors associated with gestational diabetes mellitus (GDM) and establish a risk appraisal model for GDM. METHODS: A case-control study of 156 women with GDM and 362 pregnant women without GDM was undertaken. Non-conditional logistic regression analysis was performed to identify risk factors associated with GDM and establish a prediction model. The diagnostic efficiency of this model was estimated by receiver operator characteristic curve (ROC) and Hosmer-lemeshow goodness-of-fit. RESULTS: Age, high blood pressure, history of poor pregnant outcome, obesity before pregnancy, excessive consumption of fruits, history of DM of immediate family members and taste preference were identified as risk factors of GDM. High consumption of white meat was identified as a protective factor. When the threshold value was set at 3.6, maximum sensitivity (73.7%) and specificity (68.5%) was obtained. The area under curve (AUC) of ROC was 0.79, with Hosmer-lemeshow P = 0.97. CONCLUSION: The developed model has high diagnostic efficiency, which provides a good instrument for screening women with high-risk GDM.

Association between baseline LH/FSH and live-birth rate after fresh-embryo transfer in polycystic ovary syndrome women.

This study aimed to retrospectively analyse the effect of the baseline luteinising hormone/follicle-stimulating hormone ratio (bLH/FSH) on the live-birth rate per fresh-embryo transfer cycle (LBR/ET) in infertile women with polycystic ovary syndrome (PCOS) who received a fresh-embryo transfer. A total of 424 patients with PCOS who underwent the first cycle of in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) fresh-embryo transfer at our hospital was enrolled. Univariate and multivariate logistic regression analyses, along with curve fitting and a threshold effect analysis, were performed. Baseline LH/FSH levels were a significant (P < 0.05) independent risk factor affecting live birth. In the first IVF/ICSI antagonist treatment cycles, LBR/ET after fresh-embryo transfer was relatively flat, until bLH/FSH was 1.0; thereafter, it started to decrease by 17% for every 0.1-unit bLH/FSH increase. Considering the decline in LBR/ET, it is recommended that PCOS women with bLH/FSH > 1.0 carefully consider fresh-embryo transfer during their first IVF/ICSI.

Multidimensional Assessment of Asthma Identifies Clinically Relevant Phenotype Overlap: A Cross-Sectional Study.

BACKGROUND: Asthma is a heterogeneous disease with multiple phenotypes; however, the relevance of phenotype overlap remains largely unexplored. OBJECTIVE: To examine the relationship between phenotype overlap and clinical and inflammatory profiles of asthma. METHODS: In this cross-sectional study, adult participants with stable asthma (n = 522) underwent multidimensional assessments. The 10 most common phenotypes of asthma were defined and then classified into those commonly associated with Type (T) 2 or non-T2 inflammation. Furthermore, phenotype overlap scores (POS), representing the cumulative concomitant phenotypes, were used to analyze its association with clinical and inflammatory asthmatic profiles. RESULTS: Among the 522 participants, 73.4% (n = 383) had phenotype overlap, and mixed T2 and non-T2 inflammation coexisted in 47.5% (n = 248). T2 POS was positively associated with eosinophils, IgE, and fractional exhaled nitric oxide (FeNO), and negatively with Asthma Quality of Life Questionnaire (AQLQ), sputum neutrophils, IL-17A, IL-8, and TNF-α. Non-T2 POS was positively associated with Asthma Control Questionnaire, neutrophils and sputum IL-8, and negatively with AQLQ, forced expiratory volume in 1 s, blood eosinophils, IgE, and FeNO (all P < .05). Patients with phenotypes that are associated with mixed T2 and non-T2 inflammation had elevated T2 inflammation biomarkers but worse asthma control. Both T2 (adjusted ß = -0.191, P = .035) and non-T2 (adjusted ß = 0.310, P < .001) POS were significantly associated with severe exacerbations. CONCLUSIONS: Phenotype overlap is extremely common in asthmatic patients and significantly associated with clinical and inflammatory profiles. Patients with phenotypes associated with mixed T2 and non-T2 inflammation might be unresponsive to medications owing to increased non-T2 inflammation. Multidimensional asthma assessment identifies clinically relevant phenotype overlap.

[The expression of RhoC and Ki67 in cervical intraepithelial neoplasia and squamous carcinoma of cervix].

OBJECTIVE: To detect the expression of RhoC and Ki67 in squamous carcinoma of cervix and to reveal the correlation of RhoC and Ki67 with clinic pathological parameters of cervix carcinoma. METHODS: The expressions of RhoC and Ki67 were evaluated in 26 cases of cervical intraepithelial neoplasia (CIN) and 57 cases of squamous carcinoma of cervix(SCC) by immunohistochemistry, while 14 cases of normal cervical epithelium(NCE) were taken as control. RESULTS: Immunohistochemical staining demonstrated RhoC expression in 82.46% (47/57) of SCC, 15.38% (2/13) of CIN II/III, and negative expression in NCE and CIN I. The positive rate of RhoC expression in SCC was significantly higher than that in NCE and CIN (P < 0.05). The expression of RhoC in SCC was significantly correlated with pelvic lymph node metastasis and depth of stroma infiltration, but not correlated with age, FIGO staging,histologic grade and vascular space involvement. The positive rates of Ki67 expression in NCE, CIN I, CIN II/III and SCC were 28.57%, 38.46%, 100% and 96.49% respectively. The positive rates of Ki67 expression in SCC and CIN II/III were significantly higher than those in NCE and CIN I (P < 0.05). The expression of Ki67 in SCC was not correlated with the major clinic pathological parameters. There was no obvious relationship between the expression of RhoC gene and Ki67 antigen in SCC (P > 0. 05). CONCLUSIONS: The overexpression of RhoC may play an important role in the invasion and metastasis of SCC. RhoC may be a potential marker to identify SCC patients with high risk of invasion and metastasis.

[Survivin expression in ovarian germ cell tumors].

OBJECTIVE: To investigate the relationship between the expression of survivin and the development of ovarian germ cell tumors (OGCT). METHODS: Survivin expressions in normal ovaries (n = 10) and ovarian germ cell tumors (n = 29) were detected with labelled streptavidin biotin method. RESULTS: No survivin protein was expressed in normal ovaries. Survivin protein was found in the cytoplasm and/or the nuclear of cells of 58.6% (17/29) of the ovarian germ cell tumor samples (P < 0.05). There was no significant correlations between surviving protein and the pathologic types, stage, lymphonode metastasis, AFP and volume of ascites of the tumors (P > 0.05). CONCLUSION: High expression of survivin protein may trigger the pathogenesis of the ovarian germ cell tumors.

Kangfuxinye Enema Combined with Mesalamine for Ulcerative Colitis: A Systematic Review and GRADE Approach.

OBJECTIVES: To critically appraise the efficacy and safety of Kangfuxinye enema combined with mesalamine for the ulcerative colitis (UC) patients and in addition to grade the quality of evidence by using the GRADE (grading of recommendations, assessment, development, and evaluation) approach. METHODS: A literature search was performed in the Cochrane Library, MEDLINE, EMBASE, CBM, CNKI, VIP, and WanFang Databases. The search restrictions were patients with UC and RCTs. Studies including other treatments except Kangfuxinye with mesalamine were excluded. RESULTS: Nineteen studies met the inclusion criteria. We found significant benefits of Kangfuxinye combined with mesalamine against mesalamine alone in improving response rate as well as reducing the recurrence rate and inflammation rate; meanwhile, the increase of the adverse events rate was not observed. Furthermore, the symptoms remission rate and the cure time were insignificant statistically. Additionally, GRADE results indicated that the quality of evidence regarding the above 6 outcomes was rated from very low to moderate quality. CONCLUSIONS: Although Kangfuxinye enema seems effective and safe for treating UC patients in this systematic review, Kangfuxinye enema combined with mesalamine was weakly recommended due to very low to moderate quality of available evidence by the GRADE approach.

[Survivin expression in ovarian carcinoma].

OBJECTIVE: To explore the possible relationship between expression of survivin and molecular mechanisms in patients with ovarian carcinoma (OC). METHODS: Survivin expressions in normal ovaries (n= 10), ovarian bordline tumors (n = 21), and ovarian serous cystadenomas (n = 38) were investigated by means of immunohistochemistry. RESULTS: No survivin protein was expressed in normal ovaries. Survivin protein was found in cytoplasm and/or in nucleus of tumor cell. Survivin expression was revealed in 42.9% (9/21) of ovarian bordline tumors; no significant correlation was observed between survivin expression and pathologic types or CA125 values (P > 0.05). Survivin protein was found in 76.3% (29/38) of ovarian serous cystadenomas, displaying a significantly higher expression than that in bordline tumors (P < 0.05). Survivin expression was positively correlated with tumor stage, histological grade and lymphonode metastasis (P < 0.05), whereas it was not significantly correlated with CA125 values, volume of ascites, and presence/absence of tumor cells in ascites (P > 0.05). CONCLUSION: High expression of Survivin protein may be related with the differentiation and metastasis of epithelial ovarian carcinoma.

The Association Between Metabolic Syndrome and Characteristics of Benign Prostatic Hyperplasia: A Systematic Review and Meta-Analysis.

The purpose of this systematic review was to examine the association of metabolic syndrome (MS) with measures of benign prostatic hyperplasia (BPH) including prostate growth rate, prostate volume, International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA) level, and maximal flow rate.Medline, Cochrane CENTRAL, EMBASE, CBM, and Google Scholar databases were searched until March 23, 2015 using combinations of the keywords benign prostate hyperplasia/BPH, metabolic syndrome, total prostate volume, prostate growth rate, prostate specific antigen, International Prostate Symptom Score/IPSS, maximal flow rate. Cohort or case-control studies of patients with BPH and MS that reported quantitative outcomes were included. The pooled mean differences of the outcome measures were compared between patients with and without MS.A total of 158 potentially relevant studies were identified, and 8 were included in the meta-analysis. The 8 studies included in the meta-analysis contained a total of 3093 BPH patients, wherein 1241 had MS and 1852 did not have MS. BPH patients with MS had a significantly higher prostate growth rate (pooled mean difference = 0.67 mL/y, P < 0.001) and larger prostate volume (pooled mean difference = 6.8 mL, P = 0.010) than the BPH patients without MS. There was no significant difference in IPSS score (pooled mean difference = 1.58, P = 0.202) or maximal flow rate (pooled mean difference = -1.41 mL/s, P = .345) between BPH patients with and without MS. A borderline nonsignificant difference in PSA (pooled mean difference = 0.24 ng/mL, P = 0.056) was noted between BPH patients with and without MS.The results of this meta-analysis are consistent with literature indicating that BPH patients with MS have a higher prostate growth rate and larger prostate volume than those without MS; however, further study is necessary to determine the association of BPH and metabolic disorder elements and the potential risk of disease progression in BPH patients with MS.

Traditional Chinese Patent Medicine for Acute Ischemic Stroke: An Overview of Systematic Reviews Based on the GRADE Approach.

The aim of the study is to conduct an overview of systematic reviews (SRs) to provide a contemporary review of the evidence for delivery of Traditional Chinese Patent Medicine (TCPMs) for patients with acute ischemic stroke.SRs were assessed for quality using the Assessment of Multiple Systematic Reviews (AMSTAR) tool and the Oxman-Guyatt Overview Quality Assessment Questionnaire (OQAQ). We assessed the quality of the evidence of high methodological quality (an AMSTAR score ≥9 or an OQAQ score ≥7) for reported outcomes using the GRADE (the Grading of Recommendations Assessment, Development and Evaluation) approach.(1) Dan Shen agents: tiny trends toward the improvement in different neurological outcomes (RR = 1.16, 1.10, 1.23, 1.08, 1.12); (2) Mailuoning: a tiny trend toward improvement in the neurological outcome (RR = 1.18); (3) Ginkgo biloba: tiny trends toward improvement in the neurological outcome (RR = 1.18, MD = 0.81); (4) Dengzhanhua: a tiny trend toward an improvement in neurological (RR = 1.23); (5) Acanthopanax: a small positive (RR = 1.17, 1.31) result on neurological improvement reported; (6) Chuanxiong-type preparations: neurological functional improved (MD = 2.90);(7) Puerarin: no better effect on the rate of death or disability (OR = 0.81, 95% CI 0.35-1.87); (8) Milk vetch: no better effect on the rate of death (OR = 0.66, 95% CI: 0.11-2.83);(9) Qingkailing: rate of death reduced (OR = 0.66, 95% CI: 0.11-2.83). Limitations in the methodological quality of the RCTs, inconsistency and imprecision led to downgrading of the quality of the evidence, which varied by review and by outcome. Consequently, there are currently only weak evidences to support those TCPMs.The 9 TCPMs may be effective in the treatment of acute ischemic stroke, as the GRADE approach indicated a weak recommendation for those TCPMs' usage.

Use of noninvasive ventilation at the pulmonary infection control window for acute respiratory failure in AECOPD patients: A systematic review and meta-analysis based on GRADE approach.

The aim of the study was to comprehensively examine the efficacy and safety of noninvasive ventilation used at the pulmonary infection control (PIC) window for acute respiratory failure (ARF) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD).Seven electronic databases and relevant resources were searched to identify randomized controlled trials (RCTs) comparing patients using noninvasive ventilation at PIC window with those continuing receiving invasive ventilation. Retrieved citations were screened, risk of bias was assessed, and data were extracted by 2 independent review authors. Overall effect sizes were synthesized by using meta-analyses. Quality of evidence was rated by using Grading of Recommendations, Assessment, Development and Evaluation approach.A total of 17 trials involving 959 participants were included for this review. Compared with continuous invasive ventilation, noninvasive ventilation used at PIC window significantly reduced mortality, ventilator-associated pneumonia, weaning failures, reintubations, duration of invasive ventilation, total duration of mechanical ventilation, length of stay (LOS) in intensive care unit, and LOS in hospital as well as hospital costs. Of these, mortality significantly decreased (risk ratio = 0.27, 95% confidence interval: 0.17-0.42, P < 0.001) without significant heterogeneity (I = 0%, P = 0.99). Quality of evidence regarding the 9 outcomes across the included studies was rated from moderate to low.Use of noninvasive ventilation at PIC window showed beneficial effects across identified trials for ARF in AECOPD patients. Considering the absence of high quality of available evidence and the uncertainty of long-term effect of this intervention, a weak recommendation for clinical practice was generated, and further well-designed and adequately powered RCTs are required to validate this conclusion.

The effect of testosterone replacement therapy on prostate-specific antigen (PSA) levels in men being treated for hypogonadism: a systematic review and meta-analysis.

Testosterone replacement therapy is used for the treatment of age-related male hypogonadism, and prostate-specific antigen (PSA) is a primary screening tool for prostate cancer. The systematic review and meta-analysis aimed to determine the effect of testosterone replacement therapy on PSA levels.Medline, Cochrane Library, EMBASE, and Google Scholar databases were searched until February 28, 2014, and inclusion criteria were as follows: randomized controlled trial; intervention group received testosterone/androgen replacement therapy; control group did not receive treatment; and no history of prostate cancer. The primary outcome was change of PSA level between before and after treatment. Secondary outcomes were elevated PSA level after treatment, and the number of patients who developed prostate cancer.After initially identifying 511 articles, 15 studies with a total of 739 patients that received testosterone replacement and 385 controls were included. The duration of treatment ranged from 3 to 12 months. Patients treated with testosterone tended to have higher PSA levels, and thus a greater change than those that received control treatments (difference in means of PSA levels = 0.154, 95% confidence interval [CI] 0.069 to 0.238, P < 0.001). The difference in means of PSA levels were significant higher for patients that received testosterone intramuscularly (IM) than controls (difference in means of PSA levels = 0.271, 95% CI 0.117-0.425, P = 0.001). Elevated PSA levels after treatment were similar between patients that received treatment and controls (odds ratio [OR] = 1.02, 95% CI 0.48-2.20, P = 0.953). Only 3 studies provided data with respect to the development of prostate cancer, and rates were similar between those that received treatment and controls.Testosterone replacement therapy does not increase PSA levels in men being treated for hypogonadism, except when it is given IM and even the increase with IM administration is minimal.
