Due to the irregular of diet and overfeeding greasy and surfeit flavor closely associated with hyperuricemia disease, the lipid emulsion containing high cholesterol was used to model. To obtain a more stable and sustained animal model for the efficacy evaluation of traditional Chinese herbs, we observed the influence on the serum uric acid of rat induced by the lipid emulsion compared with high purine diet. 36 SD male rats were randomized to the normal control group, high purine diet group and lipid emulsion group respectively. The general behavior, body weight and daily food intake of rats were observed. The orbital blood was taken to separate into the serum and 24 hours urine was collected. The serum indexes such as UA, BUN, Cr, ALT, AST, TC, TG, LDL-c were determined every 2 weeks, and XOD, ADA enzyme activity were determined at the 4th week. The urine indexes such as UA, Cr and Cua/Ccr were determined at the 4th week. After stopping modeling, the serum UA were determined two weeks and four weeks later respectively. At the 2nd week, the body weight and daily food intake of rats in the lipid emulsion group reduced significantly, and the level of serum UA, BUN, Cr, TC, LDL-c, ATL, AST raised significantly meanwhile TG reduced. At the 4th week, the serum UA in high purine diet group did not raise, and the serum XOD raised obviously while ADA did not; the serum UA in lipid emulsion group was higher significantly, and the serum XOD and ADA raised while Cua/Ccr reduced obviously. At the 6th weeks, the serum UA in both the high purine diet group and lipid emulsion group raised obviously. After stopping modeling, the serum UA in lipid emulsion group still maintained a high level at the 2nd week and back to the normal level at the 4th week. Compared with high purine diet, the hyperuricemia model induced by lipid emulsion forms earlierand more stable. It maybe has great value to study the pharmacodynamics of traditional Chinese medicine treatment to hyperuricemia disease. Its mechanism may be related to increasing XOD and ADA enzyme activity which can promote uric acid synthesis, meanwhile inhibiting of uric acid excretion.

Objective To investigate the clinical efficacy of intraluminal enucleation in transurethrat vapor- ization and electro-reesection of the prostate.Methods A retrospective analysis was reviewed in 62 case of prostatic hypertrophy,which were treated with intraluminal enucleation in vaporization of prostate.All pacients had a sucessful operation.There were 12 case in unipolar vaporization and 50 in plasmakenitic bipolar vaporization.Results Opera- tion time ranged from 50 to 162 minutes,with an average of 76min.Bleeding ranged from 40 to 200 ml,with an av- erage of 110ml.There was no blood transfusion.The weight of prostate was 62～138g,the catheter was maintained for 3～5 days postoperatively.The hospital stay was 7～10 days,average 8 days.All patients were cured.There was a fllow-up for 1～20 months,with an average of 8 months.The IPSS decreased by 22 points on average,and peak urine flow(Qmax)increasd to(16.8?3.3)ml/s.There wre no urethralstricture,permanent urinary incontinence, TURS,postoperative hemorrhage,retrograde ejaculation and recurrence.Conclusions Intraluminal enucleation in treatment of prostalic hypertroply is a new,safe,and effective method,which should be popularized in clinical prac- tice.

OBJECTIVETo evaluate the static and dynamic contrast sensitivity changes in myopic patients before and after laser in situ keratomileusis (LASIK).

METHODSSeventy-three eyes in 37 patients with myopia (with or without astigmatism) who received LASIK were tested for static and dynamic contrast sensitivities using the METRO VISION MON ELEC I system at 0.7, 1.4, 2.7, 5.5, 11, and 22 cpd and cps prior to LASIK, and at one-, three-, and six-month intervals after LASIK.

RESULTSAll eyes gained naked visual acuity of more than 0.5 after LASIK. The contrast sensitivity was depressed at all frequencies 1 month after LASIK, as compared to one week prior to LASIK. The depression at 2.7, 5.5, 11 (P < 0.01) and 22 cpd (P < 0.05) was statistically significant for static contrast sensitivity, and also at 5.5 (P < 0.01) and 11 cps (P < 0.05) for dynamic contrast sensitivity. Myopic eyes between 6.25 D and 14.0 D, and astigmatic eyes 2 DC and more, suffered more static and dynamic contrast sensitivity depression than the myopic eyes between 1.25 D and 6.00 D and astigmatic eyes less than 2 DC. Contrast sensitivities were improved and exceeded preoperative levels 3 months after LASIK, and improved even more 6 months after LASIK. All sequences were statistically significant for static contrast sensitivity (P < 0.01), while only 2.7, 5.5, and 11 cps were statistically significant for dynamic contrast sensitivity (P < 0.01). The astigmatic eyes 2 DC and more showed less improvement, even below the preoperative level at 1.4 cps of dynamic contrast sensitivity.

CONCLUSIONSWhile temporary depression of contrast sensitivity for myopic eyes after LASIK was seen, contrast sensitivity soon returned to exceed preoperative levels at 3 months after LASIK, while improving even more 6 months after LASIK.

OBJECTIVETo evaluate clinical result of surgical treatment for intra-articular calcaneal fractures using calcaneal anatomy plate.

METHODSFrom September 2004 to October 2009, 72 patients with intra-articular calcaneal fractures were reviewed. There were 61 males and 11 females, ranging in age from 19 to 54 years old,with an average of 39.7 years old. The course of the disease ranged from 1 to 17 days. All the patients performed X-ray and semi-coronal CT scan before and after operation. According to Sanders classification system, there were 40 cases of type III and 32 cases of type IV. All the patients were treated with lateral L-type incision and calcaneal anatomy plate. The therapeutic effects were evaluated according to the standard of calcaneal fracture of the American surgery association of foot and ankle.

RESULTSAll the patients were followed up, and the duration ranged from 10 to 48 months, with a mean of 38 months. According to standard of calcaneal fracture of the American surgery association of foot and ankle, 14 patients got an excellent result, 38 good, 9 fair and 11 poor. Five patients got incision non-union. Arthritis of subtalar joint was found in 3 cases.

CONCLUSIONOpen reduction and internal fixation of plate is effective to get good reduction for subtalar joint, which is a good method to treat intra-articular calcaneal fracture.

Objective:To examine the heritability of body mass index (BMI) and coronary heart disease (CHD), and to explore whether genetic factors can explain their correlation.Methods:Participants were from 11 provinces/municipalities reqistered in the Chinese National Twin Registry (CNTR) from 2010 to 2018. Participants data were collected from face-to-face questionnaire survey. Bivariate structure equation model was used to estimate the heritability and the genetic correlation of BMI and CHD.Results:A total of 20 340 pairs of same-sex twins aged ≥25 years were included in this study. After adjusting for age and gender, the heritability of BMI and CHD was 0.52 (95% CI: 0.49-0.55) and 0.76 (95% CI: 0.69-0.81), respectively. Further, a genetic correlation was identified between BMI and CHD ( rA=0.10, 95% CI:0.02-0.17). Conclusion:In Chinese adult twin population, BMI and CHD are affected by genetic factors, and their correlation can be attributed to the common genetic basis.

OBJECTIVETo investigate the major influence factors of child neglect among rural areas children aged 3-6 years in China.

METHODSAccording to multi-stage stratified cluster sampling, distribution characteristics and the level of economic development, we randomly sampled 10 provinces, 26 cities (8 capital cities, 16 prefecture-level cities and 2 municipalities) using lottery method. Depending on the different level of economic and cultural, we sampled one medium county from each city (municipalities sampled two counties), a total of 28 counties. All towns were divided into high, medium and low three levels in accordance with economic and cultural, each level sampled one town, each conty sampled three towns, a total of 84 towns were sampled. Each town sampled 40 children, including 20 boys and 20 girls (including each 10 children aged 3 to 6, half and half boys and girls). 4 096 rural children aged 3-6 years old were sampled and surveyed of China. Based on "the Neglect Norms for Children Aged 3 to 6 Years Old in Rural Areas of China" explored the risk factors of child neglect. SPSS 18. 0 for windows was employed for statistics analysis. Multifactorial analysis was conducted through multivariate Logistic Regression.

RESULTSThe total neglected rate of the rural children aged 3 to 6 was 53.7% (2,047/3,810), and the total neglected degree was 44.42±7.57. The multivariate logistic regression analysis showed that, neglected risk of the boys was higher than the girls (OR=1.30, 95% CI: 1.13-1.49), neglected risk of children were higher, when their mothers were migrant workers (OR=2.18, 95% CI: 1.59-3.00); the lower educational level of mothers, the higher neglected risk of children, the children in families that mothers only received primary education or was uneducated were most likely to be neglected (OR=2.92, 95% CI: 1.91-4.47), the second was the families that mothers received primary education (OR=1.86, 95% CI: 1.29-2.69); the lower the household income, the easier to be neglected the children, the easiest one was the household income less than 5000 RMB (OR=2.85, 95% CI: 2.14-3.79), the second was 5000-9,999 RMB (OR=1.76, 95% CI: 1.40-2.20); the relationship between children and mothers was distanced, neglect risk of children was higher (OR=3.88, 95% CI: 1.31-11.52); left behind children were easier to be neglected (OR=1.30, 95% CI: 1.09-1.54).

CONCLUSIONThe influence factors among children aged 3-6 years in the rural areas of China were boys, mother's occupation, maternal education level, the relationship between children and mothers, household income and left-behind children.
