RESUMEN
Objective:To evaluate the effectiveness and safety of most common used regimens against brucellosis.Methods: Search PubMed and CENTRAL database of Cochrane library for all literatures written in English about treatment of brucellosis and CBM database for all RCTs for Brucellosis in Chinese from the year 1985 till now.Assess the quality of the included literatures using Cochrane Collaboration Risk of Bias form.Combine data of relapse,total therapeutic failure,and adverse reaction of regimens for treating human brucellosis.Results: 17 literatures were included.Combined antibiotic therapeutic regimens such as DR,DS,QR and DG were compared.Rate of total therapeutic failure(RRcb:2.53,95%CI:1.51-4.23) and relapse(RRcb:2.69,95%CI:1.46-4.98) of DS regimen was lower than those of DR regimen,while adverse reaction did not show any significant differences between them(RRcb:1.40,95%CI:0.97-2.01).No significant differences were seen in rate of relapse(RRcb:1.24,95%CI:0.67-2.30) and total therapeutic failure(RRcb:1.41,95%CI:0.86-2.32) between QR and DR regimen.QR regimen had lower rate of adverse reaction than DR regimen(RRcb:1.79,95%CI:1.17-2.74).Conclusion: DS regimen priors to DR regimen.QR equals DR in treatment outcome,has fewer adverse reactions meanwhile.Triple antimicrobial based on double regimens seemed to provide better outcomes without a significant increase in adverse reaction,but more clinical evidences are still needed.
RESUMEN
Objective To study the protective effect of blueberry anthocyanins on H2O2 induced human umbilical vein endothelial cells,HUVECs.Methods The cultured cells were divided into 3 groups:normal control group,H2O2 model group,blueberry anthocyanins group.MTT method was used to observe cell viability.Annexin V-FITC/PI straining was used to observe cell apoptosis.Flow cytometry was used to detect cell cycle.Results H2O2could induce HUVECs oxidative stress injury.Cell survival rate was positive correlated with drug concentration and action time.In the certain concentration range blueberry anthocyanin had a protective effect.Conclusion Blueberry anthocyanin can protect H2O2induced oxidative stress injury in HUVECs.
RESUMEN
Objective:To investigate the expression pattern of microRNA-146a in Brucella patients and its correlation with antibody titers.Methods: By using real time PCR assay, expression levels of microRNA-146a in sera samples from 20 brucellosis patients and 20 healthy volunteers were analyzed.The correlation between expression level of microRNA-146a and serum antibody titers were analyzed with SPSS17.0.Results: A quantification curve of microRNA-146a was constructed with synthesized standard.Expression levels of microRNA-146a among brucellosis patients were significantly lower than those in 20 healthy volunteers (P<0.001).For brucellosis patients,the expression level of microRNA-146a was negatively related with antibody titers (P<0.05). Conclusion:Expression of miRNA-146a in brucellosis patients was significantly inhibited and negatively related with antibody titer.
RESUMEN
Objective:To investigate the effects of Liuweidihuang pill on the insulin levels in sera and pancreatic islets from spontaneous mouse models of human type 2 diabetes administrated with different doses .Methods:The 6-8 week-old KK-Ay mice were randomly divided into three groups including no drug control group ,low-dose group and high-dose group,in addition C57BL/6J mice were used as a genetic control group .All the animals were given with different dose Liuweidihuang pill solutions or sterile distilled water by intragastrical administration for fifteen weeks .The fasting blood glucose ,body mass and food consumption were measured weekly .The serum insulin levels were surveyed by ELISA .And the insulin levels in the pancreas islets were detected by immunofluorescence and immunohistochemistry .Results:Decreased fasting blood glucose ,controlled body mass and food consumption ,and lower levels of insulin in the sera and pancreas islets were confirmed from the KK-Ay mice administered with Liuweidihuang pill .Furthermore,the low dose program exhibits a stronger effect .Conclusion:Liuweidihuang pill has exhibited relatively therapeutic effects in the spontaneous type 2 diabetes mice including controls of hyperglycemia and body mass and relieving insulin resistance .In addition , the low-dose regimen showed even better treatment in controlling insulin levels in the sera and pancreas islets .
RESUMEN
Objective:To investigate the expression pattern of 14 innate immunity related microRNAs ( miRNAs) in brucellosis patients.Methods:By using Real time PCR assay, expression levels of 14 miRNAs in serum samples from brucellosis patients and healthy volunteers were analyzed.Results: Of the 14 miRNAs tested, 13 showed decreased expression in brucellosis patients.And significant Ct differences over one were observed for nine of the miRNAs.In them,five miRNAs,including miR-122,miR-145a,miR-155,miR-301a and miR-146a levels significantly decreased in brucellosis patients (P<0.01).Conclusion:Decreased serum levels of miR-122,miR-145a,miR-155,miR-301a and miR-146a are confirmed and may serve as novel biomarkers for human brucellosis diagno-sis.
RESUMEN
Objective The aim of this study was to observe the growth difference and expression of cytochrome C of skin hair follicles in neonatal mice .Methods The morphology of different skin hair follicles of neonatal mice ( postnatal day 1-9)were observed by HE staining histology and cytochrome C was detected by immunohistochemistry .Results The skin hair follicles in different parts of neonatal mice showed differences not only in morphology but also in developmental pe -riods.Hair follicle growth in the back and tail skin had a nonlinear and growing period .After the nonlinear and growing pe-riod they began to grow rapidly .The tail development was slightly slower than that on the back .The hair follicles of vibris-sae were very special , and started to develop without a stable period .Conclusions The results of morphological observa-tion and cytochrome C immunohistochemistry demonstrate that differences exist in the hair follicle morphology and develop -mental times in the skin of different parts of the body in neonatal mice .
