Chinese Journal of Biochemical Pharmaceutics 2017;37(2):246-248
Objective To observe the application of budesonide combined with terbutaline aerosol therapy in chronic obstructive pulmonary disease (COPD) and its influence on inflammatory factors.Methods Retrospective a total of 189 cases from May 2014 to May 2016 in our hospital were collected, they were divided them into two groups: the observation group and the control group.Observation group was given budesonide combined terbutaline aerosol therapy, total cases were 98, control group was given terbutaline atomization treatment alone, total cases were 91.The clinical efficacy of the two groups was compared, the changes of PaO2 , PaCO2 , IL-6, IL-8, TNF-α, CRP and PCT were measured before and after treatment. Results The total effective rate of the observation group was 93.9%, significantly higher than the control group 80.2%, the difference was statistically significant (P<0.05), compared with control group, the arterial blood PaO2 levels increased significantly, the difference was statistically significant (P<0.05), PaCO2 level significantly decreased, the difference was statistically significant (P<0.05), compared with the control group, the levels of IL-6, IL-8, TNF-α, CPR and PCT in the serum of the two groups decreased after treatment, and the reduces range was higher in observation group than that of control group, the difference was statistically significant (P <0.05).Conclusion Budesonide combined with terbutaline atomization could improve the level of arterial blood PaO2 , reduce inflammation, clinical curative effect were well.

Objective To prepare the sinomenine hydrochloride multivesicular liposomes with high entrapment efficiency and sustained release character.Methods Multiple emulsion method was used to prepare the sinomenine hydrochloride multivesicular liposomes.Uniform design was applied to optimize the formulation and pharmaceutical process.The shape,the particle size,and the release charcter of the liposome were evaluated.Results The sinomenine hydrochloride multivesicular liposomes prepared were spherical and the size of majority particles was in the range of 20—30 ?m and well distributed.The encapsulation efficiency was more than 80% and its in-vitro release profile accorded well with the Higuchi model with t1/2 up to 52.7 h.Conclusion The formulation and pharmaceutical process of the sinomenine hydrochloride multivesicular liposomes are stable and feasible with the high encapsulation efficiency and good sustained-release character.

Objective To establish an ideal modeling method for diarrhea predominant irritable bowel syndrome(IBS-D)with anxiely and depression in rats,and to provide a basis for the clinical study of IBS-D.Methods 60 rats were used in this study.(1)At first,20 rats were randomly divided into blank,3%acetic acid enema,4%acetic acid enema,and 5%acetic acid enema groups.After the modeling and observation period,the diarrhea status and the degree of colon injury caused by different modeling concentrations were observed by diarrhea related index and colon histopathology.(2)After the optimal modeling concentration was assessed,40 rats were randomly divided into control(a),acetic acid enema(b),acetic acid+binding(c),and acetic acid+binding+tail clip(d)groups and correspondingly treated for 8 days.After the treatments,the general condition,diarrhea-related index,open field test(OFT)score,and colonic histopathology of rats were evaluated.Results(1)Compared with the blank group,the fecal trait score of 4%acetic acid enema group was increased on days 1 to 3 after intervention(P<0.001),and gradually decreased on days 4 to 7 after intervention.After 1 week,there was no significant difference between the fecal trait score and that of the blank group(P>0.05).Body weight was lower(P<0.01),fecal water content was higher(P<0.001).Compared with blank group,body weight of the 5%acetic acid enema group was decreased(P<0.001),the fecal trait score and diarrhea index were increased(P<0.01).No significant difference was found between 3%acetic acid enema and blank groups.The pathological colon tissue showed that,compared with the blank group,the mucosal structure of the 4%acetic acid enema group was complete with a small amount of inflammatory cell infiltration,and the pathological tissue score showed no significant difference(P>0.05),whereas the 5%acetic acid enema had a medium to large amount of inflammatory cell infiltration,and the pathological tissue score was increased(P<0.01).(2)Compared with group a,group b had lower body weight(P<0.001),and higher fecal trait score,fecal water content and diarrhea index(P<0.01).Compared with a and b groups,the body weight of c and d groups was lower(P<0.001),the fecal traits score,fecal water content,and diarrhea index were increased(P<0.01),and the colon running time was decreased(P<0.01).Compared with group c,Fecal water content in group D was higher(P<0.001).In the OFT score,compared with a and b groups,the OFT distance,standing times,and upright times in c and d groups were lower(P<0.05).Compared with c,the OFT distance,standing times,and upright times in d group were lower(P<0.05).The pathological tissue of colon showed that the mucosal structure of the four groups was complete,and there were different degrees of inflammatory cell infiltration.The pathological tissue scores of groups c and d were higher than those of groups a and b(P<0.05).Conclusions The 4%acetic acid concentration is appropriate for IBS-D modeling.After superposition and binding,the IBS-D diarrhea and internal hypersensitivity characteristic state can be better simulated.After superposition of a tail clip,the IBS-D model of liver stagnation and spleen deficiency can be established successfully.
