ABSTRACT
Psoriasis is a chronic,non-infective inflammatory dermatosis characterized by erythemas covered with scales.Psoriasis is considered as a systemic disease,and several studies have confirmed that it is associated with many other diseases,such as cardiovascular diseases,obesity,diabetes mellitus type Ⅱ,dyslipidemia,nonalcoholic fatty liver disease,anxiety disorder,depression and inflammatory bowel disease.The occurrence and development of psoriasis is closely related to the immune response,and the immune dysfunction of T lymphocytes induced by the infiltration and activation of inflammatory cells has been confirmed as the key step in the pathogenesis of psoriasis.Various kinds of cytokines in the local microenvironment can promote the activation and proliferation of T lymphocytes,and regulate the differentiation of T lymphocytes into different subsets,which take an important part in the occurrence of psoriasis.In recent years,researchers have found that local microbes also play an important role in this process.Thus,this review summarizes the progress in the roles of human skin and gut microbiota in psoriasis.
ABSTRACT
0.05). The daily average intake of protein, fat and carbohydrate was similar to the RNI. The energy percentage of three meals was 4∶4∶2. Conclusions The incidence rate of hyperlipemia is high. It is a dangerous module which affects the health of the old. Thus, the diet for the old should be improved for their health.
ABSTRACT
Objective To approach the effect of Silkworm Cocoon,Portulaca oleracea on the glucose and lipid metabolism to type 2 Diabetic rats. Methods type 2 diabetic rat models induced by STZ were randomly divided into diabetes model group,Silkworm Cocoon group,Portulaca oleracea group,Silkworm Cocoon+Portulaca oleracea group,and normal contrast group,after eight weeks' intervention,We analyze blood glucose(GLU), triglyeeride(TG), SOD, GSH, MDA, calculate, the indexes of insulin resistance (HOMA-1R). Results compared with diabetes model group, the GLU in Silkworm Cocoon+Portulaca oleracea group decrease 53.3%(P<0.01) : The TG decrease 44.1%(P<0.05). the Homa-IR decrease groups has no statistic difference. Conclusion The mixture group can obviously improve the glucose and lipid metabolism、 relieve insulin resistance、 significantly increase antioxidatian、 decrease the products oflipid peroxide.
ABSTRACT
OBJECTIVE:To establish an approach to determination of ketoconazole and desamethasone acetate in novel ketoconazole spraying film.METHODS:Chromatography was performed using a Waters Symmetry C 18 .The mobile phase consisted of methyl-monopotassium phosphate(4∶1).Detection wave was at239nm.The flowing rate was0.6ml/min.RESUL_ TS:Excellent linear correlations were showed when the concentrations of ketoconazole and desamethasone acetate were in the ranges of0.2～2mg/ml and0.02～0.2mg/ml respectively.The mean recoveries of ketoconazole and desamethasone acetate were98.41%(RSD=2.29%,n=6)and97.84%(RSD=2.60%,n=6)respectively.CONCLUSION:The established approach is precise,reliable and therefore applicable to the quality control of novel ketoconazole spraying film.
ABSTRACT
Objective:To prepare a novel slow-releasing ketoconazole spraying membrane and to observe its effect on eczema and tinea corporis in guinea pigs.Methods: A novel ketoconazole spraying membrane was prepared with chitosan chlorhydrate as the membrane material.The contents of ketoconazole and desamethasone in the spraying membrane were assayed by HPLC.The separation was performed on Waters Symttry C_(18) column(250 mm?4.6 mm,5 ?m),with the mobile phase consisting methanol-potassium dihydrogen phosphate buffer(4∶1),at a flow rate of 0.6 ml/min.The dectection was carried out with a UV detector at 239 nm,at(22?2)℃.The quality criteria for the novel ketoconazole spraying membrane was established.The curative effect of the ketoconazole spraying membrane on eczema and tinea corporis was observed in guinea pigs and was compared with those of spraying membrane matrix,desamethasone antipruritics cream and compound ketoconazole cream.Results: The calibration curves of ketoconazole and desamethasone were linear between 0.2-2.0 mg?ml~(-1)and 0.02-0.20 mg?ml~(-1),respectively;the recoveries for ketoconazole and desamethasone were 98.41% and 97.84%,respectively.The intra-day and extra-day RSDs for ketoconazole were(1.17%) and 1.26%,respectively,and for desamethasone were 1.57% and 1.40%,respectively.Stimulation test showed that the spraying membrane had no irritative effect on the skin of guinea pig.The novel ketoconazole spraying membrane had similar effect on eczema and tinea corporis as those of desamethasone antipruritics cream and compound ketoconazole cream.Conclusion: This novel ketoconazole spraying membrane is easy to prepare and has obvious therapeutic effects on eczema and tinea corporis in guinea pigs,making it favourable for containing combined agents.
