RESUMO
Objective To study the effect of mitomycin C(MMC)‐chitosan (CS)sustained release microspheres on the scar‐ring prevention of the filtering passage during glaucoma filtering surgery .Methods Filtering surgery model was established on 96 eyes of 48 healthy adult New Zealand white rabbits which were divided into 4 groups ,24 eyes in each group .The right eyes implan‐ted MMC‐CS microspheres in 24 rabbits(group A) ,whereas that of the fellow eyes implanted empty CS microspheres(group B) , and in other 24 rabbits which right eyes only used 0 .20 mg/mL MMC cotton(group C) ,on the opposite sides with no adjunctive treatment(group D) .Intraocular pressure ,filtering bleb ,anterior chamber flare ,complications and the numbers of corneal endotheli‐al cells were observed after surgery .Rabbits were killed on the 7th ,14th and 21th day postoperatively in batch and histopathological examination was carried out .Results (1)the intraocular pressure:group A can maintain the low level of intraocular pressure for a long time ,followed by group C ,group B and group D ,and difference between groups was statistically significant (P0 .05) .(5)Histopathologic findings :group A had bet‐ter conjunctival epithelial integrity ,subconjunctival fibroblast less than other groups ,filtration had no obvious inflammation infiltra‐tion around the mouth area ,but also had fewer new collagen fibers .Conclusion MMC‐CS sustained release microspheres is a safe and effective treatment to inhibit inflammatory cells activity and fibroblast activity in surgery sites ,and can significantly improve outcome of filtration surgery .
RESUMO
Objective To study the effect of α-lipoic acid on the retinal expression level of VEGF and diabetic retinopathy in rats with diabetes mellitus and mechanism.Methods Totally 72 Wistar rats were divided into 4 groups:12 (control group)in group A,24 in modeling group(group B),24 in group treated withα-LA(group C)and 12 in high-glucose(group D).Group B to group D were given 60 mg/kg STZ through intraperitoneal injection,rats in group C were given 100 mg/kg α-LA and rats in group D were given 5.0% glucose-solution.The body mass,FPG,FINS,HOMA-IR,expression level of VEGF,activity of SOD,GSH and IL-6 of 4 groups were compared by statistics.Results After 72 h,the FPG of group A was(4.57 ±0.1 5 )mmol/L,that of group B was (21.72±4.28)mmol/L,that of group C was(21.54±4.96)mmol/L and that of group D was(21.83±4.77)mmol/L,the difference had statistical significance (P 0.05).The body mass,FPG,FINS,HOMA-IR,expression level of VEGF,activity of SOD,GSH and IL-6 among 4 groups at 4 w,8 w and 12 w had statistical difference (P <0.05).After 12 w,the difference of GR stage among group B to group D had statistical significance (P <0.05).Conclusion α-LA can inhibit the expression of VEGF in rats with diabetes mellitus,which is related to its ability to re-duce the oxidative stress and inflammation reaction,as well as to alleviate the insulin resistance.
RESUMO
Objective To explore the needs of the elderly patients for home care services,explore factors affecting their reception of home care services.Methods A self-designed questionnaire was used to investigate the needs of the elderly patients with chronic diseases for chronic home care services and the influential factors.Results 92.3%of the elderly patients with chronic diseases in the study needed home care services.Medical insurance,financial problems and caregiver’s quality were the key factors affecting their reception of home care,accounted for 95.5%,84.8%and 80.3%respectively.Conclusions Elderly patients with chronic diseases need home care.We should meet the needs of patients with chronic diseases by understanding their needs,carrying out multifaceted cooperation with governments and institutions,completing medical insurance system and expanding healthcare services.
RESUMO
The paper reported the topical skin antiinflammatory activity of bufexamac on inflammation model induced by formaldehyde in mice. Comparing with the blank cream, the effect of 0.5% bufexamac cre-am on inflammation had no statistically difference, but all those of 1% bufexamac cream at 1 and 2 h after treatment, of 2 % and 5 % bufexamac cream at 1, 2 and 4h after treatment, showed significantly difference. The antiinflammatory activity was enhanced with the increase of bufexamac concentration in cream. The antiinflammatory activity of 2 % bufexamac cream was close to the effects of 1 % indomethacin cream and 0.05 % clobetasol Cream.Furthermore, our study showed that steroid antiinflammatory agents and nonsteroid antiinflammatory agents were all active against erythema and edema produced by formaldehyde in mice. Formaldehyde and mice are cheap and easy to obtain in our country. It is of some value to use the animal model for screening the topical skin antiinflammatory agents.
RESUMO
Oxiconazole, a new broad-spectrum antifungal agent, was synthesized accordi ng to the method reported by Mixich G et al and some improvement was made in the preparation of N- (2, 4-dichlorobenzoylmethyl) imidazole, an important intermediate.In an effort to search for more effective antifungal drugs by chemical modification, several imidazolyl oxime ether derivatives were synthesized.The structures of the synthetic products were proved by elemental analysis.In vitro fungistatic tests showed that compounds Ⅰ-Ⅷ were more effective than clotri-mazole against most of the fungal strains tested and that compound Ⅲ possessed antifungal action against Aspergillus while others didn't.The structure of compound I(oxiconazole)was confirmed by UV, IR, 1H-NMR and MS.Its X-ray powder diffraction data are also provided.In a clinical trial,94.10% of the patients with tinea cruris were cured after a two-week oxiconazole treatments cure rate significantly higher than that of econazole(84.24%, P
