In this study, the effect of hespridin, a natural flavonoid, on renal function and morphology in streptozotocin induced diabetic rats was evaluated. The result was compared with that of aminoguanidine which can inhibit the formation of advanced glycosylation end products (AGEs) and can decreased diabetic complications in experimental diabetes. The results showed that excretion of urinary protein, and the content of AGEs and LPO decreased, while the mesangial expansion and basement membrane thickening were retarded in diabetic rats treated with hespridin. These indicate that hespridin plays the same protective role as aminoguanidine in inhibiting formation of AGEs, thus preventing the development of nephropathy in STZ induced diabetic rats.

The implant-supported prosthesis has gradually become the preferred treatment for patients with partial edentulous or complete edentulous. Causes for the implant failure have been discussed in the majority of studies conducted in recent years, while their risk factors are still controversial. Patient factors (gender, age, smoking, osteoporosis, diabetes, medication, periodontitis and bruxism), clinical parameters (implant area, bone quality, implant size) and doctor factors (surgical-related factors, prosthesis-related factors) will all affect implant failure. This article presents typical clinical cases and reviews the potential risk factors for dental implant failure, in order to provide guidance for clinical practice.

ObjectiveTo explore the best practice and normalization of arterial blood collection by comparing performance of BD preset syringe with regular syringes in arterial blood collection in standardized nursing process. MethodsThe nurses were trained to use BD preset syringe and regular syringes to collect arterial blood sample.Five hundred subjects were randomly divided into the preset syringe group and the regular syringes group,250 subjects in each.Agglutination of blood samples was observed.Time spent in every step of collections was recorded for 23 subjects in each group to calculate workflow efficiency.A questionnaire was used for nurses participated in arterial blood collection for their evaluation of both types of syringes. Results The incidence of micro-clot formation in the preset syringe group was 2 cases,lower than 15 cases in the regular syringes group,the preset syringe group also showed higher workflow efficiency as well as safe and easy-to-use characters.The difference between two groups was statistically significant. ConclusionsUsing BD preset syringe in nursing process management has lower incidence of micro-clot formation,higher workflow efficiency,safe and easy-to-use character.It should be promoted in clinical practice.
