Aim To investigate the effect of allopurinol and benzbromarone on serum level of uric acid, hepatic xanthine oxidase(XOD) activity and intestinal expression of glucose transporter(GLUT) 2 and 5 in rats with fructose-induced hyperuricemia.Methods Wistar rats were fed with 10% fructose in drinking water for consecutive 8 weeks to induce HUA.Treatment with 5 mg·kg-1 allopurinol or 10 mg·kg-1 benzbromarone were intragastricly administered from 5~8 weeks.Serum level of uric acid and XOD activity in liver were tested.Expression of GLUT2 and GLUT5 in intestine was analyzed by immunohistochemistry staining and Western blot.Results Treatment with allopurinol or benzbromarone significantly decreased the serum level of uric acid in fructose-induced hyperuricemic rats.At the same time, allopurinol treatment significantly reduced the XOD activity in liver and GLUT5 expression in intestine.Nevertheless, benzbromarone treatment did not show inhibitory effect on hepatic XOD activity and intestinal GLUT5 expression.In addition, neither allopurinol nor benzbromarone showed inhibitory effect on GLUT2 expression in intestine.Conclusions Allopurinol decreases serum level of uric acid in fructose-induced hyperuricemic rats.The mechanism is related to reducing XOD-mediated uric acid production in liver, and decreasing GLUT5-mediated fructose absorption in intestine.

OBJECTIVE:To investigate the effect of rapid rehabilitation surgery assisted to fluorouracil,oxaliplatin,leucovo-rin(FOLFOX)on postoperative recovery,complications and quality of life in patients with colorectal cancer. METHODS:60 pa-tients with colorectal cancer were randomly divided into control group(30 cases)and observation group(30 cases). After resection of colorectal cancer,control group received 85 mg/m2 Oxaliplatin for injection,2 h intravenous infusion,d1+200 mg/m2 Calcium le-vofolinate for injection,intravenous infusion,once a day,d1-2+400 mg/m2 Fluorouracil injection,intravenous infusion,once a day, d1-5 then 600 mg/m2 for 22 h intravenous infusion,d1-2. Observation was additionally given rapid rehabilitation surgery. 2-week was regarded as 1 course,it lasted 12 courses. Urinary retention time,anal exhaust time,first defecation time,postoperative hospital-ization time,scores of life quality (overall health,emotional function,mental health,physiological functions,physical function,so-matic pain,vitality,social function)in 2 groups were observed,and the incidence of postoperative complications was recorded. RE-SULTS:The urinary retention time,anal exhaust time,first defecation time,postoperative hospitalization time in observation group were significantly shorter than control group,the incidence of postoperative complications in observation group was signifi-cantly lower than control group,overall health,emotional function and mental health score were significantly higher than control group,the differences were statistically significant(P<0.05),but there were no significant differences in physiological functions, physical function,somatic pain,vitality,social function score in 2 groups (P>0.05). CONCLUSIONS:Rapid rehabilitation sur-gery assisted to FOLFOX chemotherapy can reduce the incidence of postoperative complications in patients with colorectal cancer, improve quality of life,shorten hospitalization time and promote postoperative recovery.

Objective: To observe the effect of mild moxibustion on cancer-related fatigue, serum ghrelin and adiponectin in patients undergoing chemotherapy after colorectal cancer surgery. Methods: Seventy patients were divided into a control group and an observation group according to the random number table method, with 35 cases in each group. Patients in both groups were treated with conventional FOLFOX4 chemotherapy regimen. Patients in the control group also received routine treatments such as symptomatic treatment of complications, health education, nutritional support, and exercise intervention. Patients in the observation group received mild moxibustion on the basis of interventions used in the control group. The Piper fatigue scale-revision (PFS-R), Karnofsky performance status (KPS) and spleen and kidney yang deficiency syndrome were scored, and serum ghrelin and adiponectin levels were measured before and after treatment. Results: After treatment, total score of PFS-R in the control group did not change significantly (P>0.05), while in the observation group it was significantly reduced (P<0.05) and lower than that in the control group (P<0.05); KPS scores in both groups were increased (both P<0.05), and it was significantly higher in the observation group than in the control group (P<0.05); total score of spleen and kidney yang deficiency syndrome in the control group did not change significantly (P>0.05), while it was significantly reduced in the observation group (P<0.05) and lower than that in the control group (P<0.05); serum ghrelin and adiponectin levels in the control group had no significant changes (both P>0.05), but the levels were significantly increased in the observation group (both P<0.05) and higher than those in the control group (both P<0.05). Conclusion: Based on the routine treatments, mild moxibustion can relieve fatigue, improve quality of life, and improve the symptoms of spleen and kidney yang deficiency in patients undergoing chemotherapy after colorectal cancer surgery, which may be related to the regulation of serum ghrelin and adiponectin levels.

Background Keratoconus is a progressive corneal thinning and protrusion disease that develop in the age of puberty,resulting in a certain extent impairment of visual function.Corneal collagen cross-linking (CXL) increases the stiffness of the cornea through the photooxidation of ultraviolet A (UVA) and riboflavin,with the aim to postpone and prevent the progression of keratoectasia.Objective This study was to evaluate the safety and efficacy of transepithelial CXL in the treatment of pediatric keratoconus.Methods Ten eyes of 9 pediatric patients with keratoconus undergoing transepithelial CXL were enrolled from February 2010 to March 2013 in Affiliated Eye Hospital of Wenzhou Medical University,with the mean age was (15± 1) years (range from 13 years to 17 years).After topical anesthesia (0.1％ tetracaine) for 15 minutes,0.5％ riboflavin was applied until it was saturated in the anterior chamber,then UVA with the intensity of 3 mW/cm2 was performed on the cornea for 30 minutes.The uncorrected distance visual acuity (UDVA),corrected distance visual acuity (CDVA),refractive error,topography,corneal thinnest thickness were measured 7 days,1 month,3 months,6 months and 1 year after operation.Endothelium cell density (ECD) was measured 7 days afier operative.Results The mean corneal reepithelization time was (1.4±0.8) days.The UDVA and CDVA were significantly improved from preoperative 1.02±0.16 and 0.34±0.20 to postoperative 0.77±0.18 and 0.25 ±0.15,respectively (t =4.251,3.750;both at P＜0.05).The refractive sphere and spherical equivalent significantly changed from preoperative (-7.15±3.00)D and (-9.26±3.23)D to postoperative (-5.28±2.05) D and (-7.05±2.08) D 1 year,respectively (t =-2.515,-2.597;both at P＜0.05).Maximum Kvalue (Kmax) was significantly decreased from preoperative (64.1 ± 11.9) D to postoperative (61.8 ± 10.4) D (t =2.304,P＜0.05).The refractive cylinder,corneal thinnest thickness and ECD showed no significant differences between preoperation and postoperation (t =-1.331,0.328,1.205;all at P＞0.05).Stromal opacity was observed in 2 eyes 3 months and 6 months after operation,respectively.Conclusions Transepithelial CXL is safe and effective in prolonging or halting progression in adolescent keratoconus.

Objective To evaluate the correlation of the depths of detecting arteries vessel in transcranial dopplor(TCD) and child head circumference.Methods Five hundreds and eighty-eight health children were selected at random for the study. TCD ultrasonography was used to detect the optimal depths of arteries, middle and anterior and posterior cerebral arteries for each child, together with the head circumference.Results The data showed that the depths of detecting cerebral arteries significantly changed in different age groups, probably due to the growth of the head circumference.Conclusion There was close relationship between the depths of detecting cerebral arteries and child head circumference, which is of clinical significance.
