Residues and analysis methods of phthalate esters plastificator in various plastics of vinyl chloride are presented,and the wide-use and high environment burden of these chemicals is indicated.The categories and toxicity of phthalate esters that might have the effects of environmental endocrine-disrupting chemicals are introduced.It is shown by the current studies that the effects of these chemicals on laboratory animals were focused on procreation toxicity such as spermaduct atrophy and ovulation clog,etc.It is suggested that more investigation of these chemicalspotential toxicity should be made and preventive measures should be taken promptly.

Referring to the literatures recent years about mechanisms and reasons of Vertebral Artery Morphological Caused Vertigo,this article illuminates the category of this kind of disease,and for these reasons to find out corresponding therapy by tuina,then proposes the insufficiency and the expectation in this special disease.

Objective:To observe and compare the wound healing effects,the time and costs of hospitalization of the two drainage ways in the breast polyacrylamide hydrogel removing operations by a prospective randomized controlled approach.Methods:From December 2004 to December 2009,a total of 54 breast-side of 40 patients,whose incision were not healing after breast polyacrylamide hydrogel removing operations,were divided into two groups.Both gorups'skin incision were on the areola or inframammary crease.In the case of removing the polyacrylamide hydrogel during the operation as much as possible,a new incision,approximately 1.5cm,was produced below the inframammary crease approximately 5cm,the negative drainage tube was inserted into the new incision in the A group(distal drainage way),While the negative drainage tube was inserted into the original incision in B group(In-situ drainage way).Results:The breast appearance was flat and thin,the texture was soft and there was no mass or sclerosis.There were significant differences between the two methods in primary healing,the time and costs of hospitalization.Conclusion:The clinical effect of the distal drainage way is better than the clinical effect of the In-situ drainage way,and it deserves to apply in clinical practice.

Objective To investigate the mechanism of anti-IL-17A monoclonal antibody(secukinumab) regulating autophagy and inflammation in gout.Methods The peripheral venous blood samples from 57 patients with acute gout(AG),57patients with intermittent gout(IG) and 82 healthy volunteers were collected and measured for the mRNA transcription levels of autophagy-related genes(ATGs) ATG4B,ATG7, A TG16L1,Beclin-1 and LC3B by RT-qPCR.The model of AG inflammation was established by adding monosodium urate(MSU) crystals into the peripheral venous blood samples of healthy volunteers,and the transcription and protein expression of IL-1β were detected by RT-qPCR and ELISA at 0,1,2,4,6 and8 h and different concentrations(0,100,200 and 400 μmol/L) of secukinumab.The peripheral blood samples of healthy volunteers were divided into control(without MSU treatment),MSU(100 μg/mL),MSU+colchicine(100 μg/mL+30 μg/mL) and MSU+secukinumab(100 μg/mL+400 μmol/L) groups,which were detected for the mRNA transcription and protein expression of IL-1 β and ATGs by RT-qPCR and Western blot,and for the expression of IL-1β,IL-12 and IL-35 by ELISA.Results The mRNA expression levels of ATG4B, Beclin-1 and LC3B in AG,IG and healthy control groups were significantly different(F=3.896,11.78 and 3.856,respectively,each P <0.05),among which the mRNA levels in AG were lower than those in IG and HC groups(t=2.692,3.234,2.231 and 2.085,4.795,2.748,respectively,each P <0.05);the expression levels of ATG16L1 mRNA were significantly different in the three groups(F=7.949,P <0.001),and was significantly lower in AG group than HC group(t=3.860,P <0.001).In AG inflammation model,the mRNA and protein expression of IL-1 β reached their peak in 2—4 h,and the anti-inflammation effect of secukinumab was the strongest at the concentration of 400 μmol/L.Compared with MSU group,the mRNA levels of ATG16L1 and LC3B(t=2.343 and 2.916,respectively,each P <0.05) as well as the expression levels of ATG4B,ATG7,Beclin-1,ATG16L1 and LC3B-Ⅱ proteins(t=28.84,11.6,8.402,4.124 and 2.458,respectively,each P <0.05) in MSU+secukinumab group decreased significantly.The expression levels of IL-12 and IL-35 in the control,MSU,MSU+colchicine and MSU+secukinumab groups showed significant difference(F=7.009 and 6.518,respectively,each P <0.01).Compared with MSU group,the expression level of IL-12 significantly decreased(t=2.604,P <0.05)in MSU+secukinumab group,and the expression level of IL-35 also decreased,while with no significant difference(t=1.928,P> 0.05).Conclusion Secukinumab can regulate the mRNA and protein expression of ATGs,reduce the levels of pro-inflammatory cytokines,and inhibit gout inflammation,which provides a reference for the treatment of gout.

Objective To investigate the sedative effects of different fractions of patrinia scabiosaefolia fisch. in mice and provide some valuable information for isolating components with sedative effect.Methods Petroleum, acetic ether and n-butanol fraction was isolated from the patrinia scabiosaefolia fisch.. The sedative effects were determined with locomotor activity assay, hole board test and sodium thiopental-induced sleeping time assay, and it was compared with the effects of total 70% ethanol extract. Results N-butanol fraction showed better sedative effect compared with others, and it was in a dose-dependent manner. Conclusion The results showed that the main active principles of patrinia scabiosaefolia fisch. were the n-butanol fraction, and the promising active chemical might be obtained from this fraction.

Objective To observe the clinical effect of postoperative complications in patients with induced abortion by taking Drospirenone and Ethinylestradiol Tablets.Methods 400 patients with induced abortion from November 2015 to May 2016 were randomly divided into the observation group and the control group,200 cases in each group.The control group was treated with routine antibiotic therapy.The observation group treatment with Drospirenone and Ethinylestradiol Tablets based on the control group, 1 per one night, 21d for a course of treatment, continuous use of 6 courses.Compared the 2 groups of patients with postoperative complications of pelvic infection,intrauterine adhesions,pregnancy,recurrent abdominal pain and two groups of postoperative recovery time of menstruation,vaginal bleeding,endometrial thickness.Results In the observation group after pelvic infection,uterine cavity adhesion,pregnancy,periodic abdominal pain incidence were 1.5%,0.5%,0.0%,1.5%,were significantly lower than that of the control group7.0%,3.5%,4.0%,5.5%(P<0.05);the observation group after menstruation recovery time,vaginal bleeding,endometrial thickness respectively(27.2 ±1.7) d,(6.2 ±1.4)d,(7.2 ±2.3) mm,were lower than the control group(32.5 ±6.0) d,(7.8 ±2.7) d,(5.0 ±2.4) mm,two groups of the difference was statistically significant(P<0.05).Conclusion After artificial abortion,taking Drospirenone and Ethinylestradiol Tablets can effectively reduce the incidence of complications,improve the quality of life of patients,the method is simple,safe,effective and good compliance.

The stem cell is a class of primitive cells with self?renewal,and multiple pluripotent potential capacities,which can differentiate into multiple specialized cells and generate human organs and tissues. Stem cell therapy is an interventional treatment that introduces new stem cells to damaged tissues,which facilitates the regeneration of trauma,disease and ageing?in?duced damaged human tissues to repair or replace the damaged tissues,thereby achieving the goal of disease treatment. It has been proved that the stem cell therapy is effective in the treatment of multiple human diseases,including cancer,diabetes,neu?rological disorders,autoimmune diseases,cardiovascular disorders and blood diseases. This review summarizes the advances in the research of stem cell therapy for human parasitic infections.

Necrosis is also tightly controlled by signaling path-ways,thus it is called as regulated necrosis,which includes ne-croptosis,ferroptosis,parthanatos and CypD-mediated necrosis. It has been shown that regulated necrosis is closely related to the occurrence,development and prognosis of injury-relevant disea-ses such as myocardial infarction,stroke,neurodegenerative dis-eases.It will be significant for prevention and therapy of injury-relevant diseases to clarify the signal transductions and regulatory mechanisms for the regulated necrosis.
