AIM: To observe the effect ofacacia honey (AH) on serum uric acid level and renal function in potassium oxonate modelrats after drinking AH aqueous solution. METHODS: Sixty male SD rats were selected and randomly divided into control group (CON group), potassium oxonate model group (OA model group), 10% fructose group (10% F group) and different concentration honey groups (25%, 12.5% and 6.25% AH groups). All rats were fed with normal diet.The rats in CON group were subcutaneously injected with 5% sodium carboxymethyl cellulose (CMC-Na) solution and drunk sterile water every day, while rats in other groups were injected with 100 mg / kg OA solution suspended with 5% CMC-Na subcutaneouslyand drunksterile water orfructose solution or AH solution of different concentrations every day. Before and during the 4-week test, rats were weighed and blood was taken once a week. At the end of test, urine and feces specimens or kidney tissues were collected and blood was taken from the abdominal aorta. The uric acid content in blood, urine, and feces and the levels of serum creatinine (Cre) and blood urea nitrogen (BUN) or inflammatory factors in kidney tissues were measured. Renal function and histology were evaluated. RESULTS: Compared with CON group, AH could significantly reduce the body weight of rats (P<0.05), increase the kidney organ coefficient, the levels of serum uric acid, and uric acid in urine or feces, and reduce the level of fecal uric acid (FUA) in rats. AH can down regulate the level of tumor necrosis factor alpha (TNF-a) (P< 0.05) and up regulate the expression of monocyte chemoattractant protein 1 (MCP-1) and transforming growth factor β - 1 (TGF - β1) in rats kidneys; AH can cause slight to mild dilatation of renal tubules and mild to moderate basophilic lesions of renal rubules in rat kidney in a dose dependent manner. CONCLUSION: In the doses rang of present study, AH can cause hyperuricemia, renal tubular dilatation and basophilic lesions, and lead to renal function damage in rats.

ObjectiveTo explore the sensory processing characteristics of preschool children with autism spectrum disorder （ASD）， and to provide a theoretical basis for early screening and intervention training of ASD. MethodsA total of 215 preschool children with ASD and170 typically developed （TD） children were investigated with a basic situation questionnaire and sensory processing measure （SPM）. The two groups were stratified according to age and gender， and the differences of scores in sensory domains were compared to analyze the sensory processing characteristics of preschool children with ASD. ResultsThe scores of social participation， vision， hearing， touch， taste and smell， body awareness， balance and motion， planning and ideas， and total sensory system in children with ASD were all higher than those in children with TD （all P<0.01）. The highest degree of abnormality was found in hearing and the lowest degree in taste and smell in children with ASD. The results of Spearman correlation analysis showed that in the 4-year-old and 5-year-old children with ASD， the scores of vision （r_s=-0.200， P= 0.033） and hearing （r_s=-0.194， P=0.040） decreased with age. There was no correlation between the scores of other developmental quotients and age （all P>0.05）. Boys and girls with ASD had higher scores in all developmental quotients than TD children （P<0.01）. However， there was no significant gender difference in any developmental quotients of ASD children （all P>0.05）. ConclusionSensory processing abnormalities are common in preschool children with ASD， which are different from those of TD children in multiple sensory domains. Sensory processing abnormalities may be used as an indicator for early screening of ASD， and it is necessary to conduct corresponding intervention training for sensory processing abnormalities in children with ASD.
