Objective Increased serum uric acid level is associated with type 2 diabetes (T2DM) through the mechanism of oxidative stress.As the rate-limiting enzyme in the degradation of purines in humans,xanthine oxidoreductase (XOR)catalyzes the final two reactions of purine catabolism,oxidizing hypoxanthine to xanthine,and xanthine to uric acid.The aim of this study is to investigate the association between serum XOR activity and T2DM.Methods A total of 270 patients with T2DM and 140 age-and-gender-matched health controls were enrolled in the study.The clinical examinations such as weight and height were conducted in the morning after an overnight fast.Serum XOR activity and other biochemical parameters like triglyceride,total cholesterol,high density lipoprotein cholesterol,fasting plasma glucose and uric acid levels were measured.Results Serum XOR activity was significantly elevated in T2DM patients compared with that in the controls (31.2 ± 8.91 vs 4.6 ± 0.91 U/L,P ＜0.01).Serum XOR activity was significantly elevated in T2DM patients complicated with lower extremity arterial disease compared to that in patients without lower extremity arterial disease (42.1 ± 8.43 vs 23.7 ± 5.31 U/L,P ＜ 0.01).Conclusion High XOR activity plays an important role in onset and development of T2DM.

Objective To observe the effects of auditory integration training on language development delay in mental retardation children.Methods 40 cases were devided into observation group (n=20) and control group (n=20). All the children accepted speech training,while the observation group accepted auditory integration training in addition. They were assessed with the development quotient (DQ) of adaptability and language of Gesell developmental schedules before and 6 months after treatment. Results DQ of adaptability and language improved after treatment in both groups (P<0.05), and improved more in the observation group than in the control group (P<0.05). Conclusion Auditory integration training may further improve the language development in mental retardation children.

Objective To study the relationship among iron metabolism indicators in the patients with hepatitis B and to analyze their clinical significance.Methods Serum ferritin,iron and hepcidin were detected in 96 cases of hepatitis B and 58 negative control subjects.The above indicators detected results and their relationship were analyzed.Results Compared with the control group,ser-um ferritin and serum iron concentration in the hepatitis B group were increased,he difference was statistically significant (P <0.05);serum ferritin and serum iron concentration in the hepatitis B group demonstrated the positive correlation (P <0.05);serum ferritin in the patients with hepatitis B was negatively correlated with hepcidin (P =0.018).Conclusion The patient with hepatitis B often have the iron metabolism abnormality,and the iron metabolism indicators is expected to be an assessment indicator of treat-ment and prognosis in the patients with hepatitis B.

Objective: To analyze the clinical value of modified endoscopic nipple resection in duodenal papillary adenoma resection Methods: 40 patients with duodenal papillary adenoma were randomly divided into observation group (20 cases) and control group (20 cases)according to the random number table. The patients of control group were treated by conventional resection of papillary adenoma, while the patients of observation group were treated by modified endoscopic nipple resection. The resection rate and the implantation of stent between the two groups were compared. Besides, the occurrence rate of complication and postoperative follow-up between the two groups also were compared. Results: The complete resection rate of observation group (95.00%) was not significant difference with that of control group (90.00%), while en bloc resection rate of observation group (85.00%) significant higher than that of control group (55.00%) (x2=4.28, P<0.05).There was not statistically significant difference between the two groups about the implantation of stent (x2=0.36, P>0.05). In postoperative three months, the difference of recently complication between the two groups was significant (x2=6.14, P<0.05). While the difference of long-term complication between the two groups was no significant (x2=0.36, P>0.05) in more than postoperative three months. After the follow-up of one year, the recurrence rate of observation group (10.34%) was no significant with that of control group (14.29%)(x2=0.17, P>0.05). Conclusion: The modified endoscopic nipple resection can enhance the en bloc resection rate, and reduce the incidence of complications and the recurrence rate. Besides, it has many dominances including higher feasibility in clinical practices. Therefore, its promotion is worthy.

Objective To explore the effect of oris(oral)muscles training on speech language rehabilitation for autism spectrum disorders children.Methods 40 cases were divided into 2 groups,20 cases in each group.The control group was treated with language cognitive training.The observation group was treated with language cognitive combined with oris(oral)muscles training.The treatment was given for 6 months.S -S(sign -significate relationgs) was used to evaluate the language development quotient of the two groups.Results After treatment,the language development quotient was significantly improved compared with before treatment(P <0.05),and the language expres-sion quotient of the observation group was more effective than the control group(t =2.434,P <0.05).The language comprehension quotient and operation quotient of the two groups had no significant differences.Conclusion Oris muscles training combined with language cognitive is more effective on language expression capability of autism spec-trum disorders children.

Objective To investigate the clinic effects of transcatheter arterial chemoembolization (TACE) combined with injection of hyper- thermic lipiodol into tumor body in treating large hepatic carcinoma. Methods A total of 86 patients with primary hepatic carcinoma were randomly and equally divided into the study group (n = 43) and control group (n = 43). TACE combined with injection of hyper-thermic lipiodol into tumor body was carried out in the patients of the study group , while only TACE was performed in the patients of the control group. The results were compared between the two groups. Results The effective rate of the study group and the control group was 68%and 53%respectively , and the difference between the two groups was statistically significant. The difference in the changes of tumor size after the treatment between the two groups was also statistically significant. In the study group, the survival rates at 6, 12, 18 and 24 months after the treatment were 100% (n = 43), 84% (n = 36), 53% (n = 23) and 33%(n=14) respectively, while in the control group the survival rates were 94% (n=40), 70% (n=30), 37%(n = 16) and 21%(n = 9) respectively. No statistically significant differences in postoperative liver function damage existed between the two groups. Conclusion TACE combined with injection of hyper-thermic lipiodol into tumor body is obviously superior to routine TACE in treating large hepatic carcinoma.

Objective: The aim of the present study was to evaluate the stability of native bovine ? casomorphin 7 in duodenum of adult rats, and the local effect on expression of cholecystokinin in intestinal mucosa. Method: (1) According to the variety of infused ? casomorphin 7 concentrations between absorptive and un-absorptive groups in vivo, its characteristic absorption in duodenum was observed. (2) To characterize the stability of the ? casomorphin 7, rat intestinal mucosa homogenate was digested and the enzyme activities were determined in vitro. (3) The effect on cholecystokinin mRNA expression of ? casomorphin 7 after luminal administration was analyzed by RT-PCR. Results:? casomorphin 7 was unable to be absorbed by intestinal epithelia and quickly degraded in the intestinal tract. It contributed to elevate cholecystokinin mRNA expression in intestinal mucosa and this effect was partly blocked by naloxone. This peptide also significantly inhibited the somatostatin mRNA expression. Conclusion: The present data demonstrated that the local effect on expression of cholecystokinin of ? casomorphin 7 might be related to opioid system and directly or indirectly affected by somatostatin.
