Objective To study intervention effect of diet habits according to Trans-theoretic Model (TTM) in young and middle-aged patients with asymptomatic hyperuricemia. Methods 120 patients were divided into the intervention group (n=60) and the control group (n=60). The nursing intervention by stages of TTM was implemented to a total of 56 patients in the intervention group in the study. Routine nursing care was taken to 57 patients in the control group. Patients were evaluated by self-designed questionnaire after 1, 3 and 6 months of the intervention in the two groups respectively, including the diets of patients, the change of patients′ eating habit, differences of uric acid, total cholesterol, triglycerides, blood sugar. Results The patients′ intake of beer, seafood, meat, edible oil in the intervention group was lower than the patients′ intake in the control group, while the patients′ intake of fruits and vegetables was higher than the patients′intake in the control group after 1, 3 and 6 months of the intervention, which was statistically significant ( P < 0.01). Compared with 27 cases in the control group, 53 cases in the intervention group were in action phase and maintenance phase after 6-month intervention, the difference was statistically significant (P < 0.01). After six months′intervention, the patients′uric acid, triglycerides in the intervention group was (418.01 ± 24.15)μmol/L and (1.52 ± 0.56) mmol/ L respectively, which was significantly lower than (435.02 ± 26.35) μmol/ L and (2.45 ± 0.74) mmol/L in the control group, t values were-3.47 and 2.20 respectively, P<0.01. Conclusions Diet intervention based on the TTM can effectively promote the change of patients′ unhealthy eating habits, improve self-management skills, and reduce uric acid, which is worthy of generalizing.

AIM: To study the EBV LMP-1 gene integrated in the chromosome of poorly differentiated nasopharyngeal carcinoma cell line SUNE-1. METHODS: The LMP-1 gene of SUNE-1 was detected with PCR; Deletion of LMP-1 was examined by restriction endonuclease analysis and PCR. The deletion was precisely localized by DNA sequencing. RESULTS: The LMP-1 gene integrated in the chromosome of SUNE-1 could be deleted or non-deleted. The two introns of LMP-1 gene were shown being lost in SUNE-1 cell line. CONCLUSION: Deletion of intron 1 and intron 2 happen in some of the LMP-1 gene integrated in the chromosome of SUNE-1.
