Lipoprotein lipase (LPL) is the rate-limiting enzyme for the hydrolysis of the triglyceride core of circulating triglyceride-rich lipoproteins.LPL can not only affect the lipoprotein level,but also play an important role in the development of atherosclerosis.LPL gene polymorphisms may affect LPL activity,and therefore have both pro-and anti-atherogenic effects.This article reviews the relationship between LPL gene polymorphism and atherosclerosis.

Objective To explore the effect and mechanism of aerobic exercise on islet β-cells in type 2 diabetic rats.Methods Thirty healthy SPF 8-week old Wistar rats were randomly divided into control group (C, n=10), diabetic control groups (DMC) and diabetic exercise (DME) groups, 10 rats in each group, among which 7 successful rat models were used in the experiment.The diabetic rat model was established by high fat and sugar diet and i.p.injection of streptozotocin in a dose of 50 mg/kg.The rats of group DME were forced to perform 20 m/min running for 30 min, once a day, 6 days in a week, for 8 weeks.Other rats were allowed free movement.At the end of experiment, serum glucose and insulin were measured and homeostasis model assessment (HOMA) was calculated, and pancreatic tissue samples were collected for histopathological examination.The morphology and structure of pancreatic islets were observed under a digital microscope, the perimeter and area of islets were analyzed by image analysis, and shape factor of islets was calculated.The insulin content, glucokinase and ultramicro-ATPase activity in the pancreatic homogenate were determined.Results In the DME group, the perimeter and area of islets were significantly higher than the DMC group (P< 0.05), but still lower than the control group.The shape factor was significantly increased, the cell hypertrophy, vacuolization and nuclear pyknosis were markedly alleviated than those in the DMC group, the insulin content, glucokinase and the trace total ATP activity in the DME group were significantly higher than those in the DMC group (P<0.05), and the SF and HOMA were significantly changed.Conclusions Aerobic exercise can reduce the blood glucose level, improve the morphology of islets and β-cells in the type 2 diabetic rats.It may be due to increase of the activity of glucose kinase and ATP-synthase, and increased insulin sensitivity in the pancreas.

Acalculia has been defined as an acquired disturbance in number processing and computational ability. Acalculia which caused by various diseases has a great effect on activity of daily living. This article presents a review of Standardized Tests of Acalculia(including EC301 calculation and number processing battery, Number Processing and Calculation battery and Johns Hopkins Dyscalculia Battery) and cognitive rehabilitation for acalculia. The main strategy for rehabilitation is to re-teach lost knowledge via extensive practice according to the evaluative results. Those are described in 5 domains: the understanding of numbers, number transcoding, arithmetical facts, complex calculation and mathematics applications.

AIM: To investigate the difference of cognitive impairment and depression between age-related macular degeneration ( AMD ) group and the control group patients. ·METHODS: A prospective case-control study was performed from November 2014 to August 2016 in the hospital for AMD patients and sex-matched control group. The Mini-Mental State Examination ( MMSE) and the Geriatric Depression Scale ( GDS ) score of each patient were collected for statistical analyzing. ·RESULTS: There were total 84 cases ( 168 eyes ) included in the study. The difference of visual acuity between the two group was statistically significant ( F=8. 953, P=0. 004) by baseline data analyzing. There were no significant differences in MMSE scores between the two groups according to educational status ( P>0. 05 ) , while the prevalence of cognitive impairment in each group was statistically significant (x2 =4. 14, P=0. 042). The difference of GDS scores, prevalence of total and mild depression between two groups were both statistically significant (F=5. 852, P=0. 018; x2=6. 372, P=0. 012; x2 = 5. 674, P = 0. 017 ). However, there was no statistically significant difference in the prevalence of moderate to severe depression (x2=0. 672, P=0. 412). ·CONCLUSION: AMD patients have a higher prevalence of depression. Although MMSE score differences were not statistically significant in subgroup analysis by educational levels, AMD patients are more likely to have cognitive impairment overall.

Objective To introduce a new surgical method of reconstructing A ch illes tendon by transfer of the soleus tendon flap. Methods The method was desig ned on the basis of the anatomical characteristics of the superficial muscles as sociated with Achilles tendon. It was applied to treat 12 patients with Achilles tendon defects. These patients were followed up for 0.5 to 6 years (average 39 months). Results The curative effect of the method were assessed according to Ar ner-Lindholms evaluation criteria. 9 cases were rated as excellent, 2 fine an d 1 poor, with the total excellent and fine rate being 92%. Conclusions ①Misdi agnosis and improper initial treatment are the major causes of Achilles tendon d efects. ②Systematic training after operation is very important for good curativ e effects. ③The method mentioned above brings about less trauma, less negative effects on blood supply to Achilles tendon, and good healing after operation.

Response surface methodology (RSM) based on a three-level three-factor Box-Behnken design of experiments was used to optimize the extracellular polysaccharide content and the mycelium biomass by submerged cultivation using Pholiota squarrosa AS 5.245. The critical factors selected for the investigation were temperature, time of cultivation and volume of medium, based on the results of our previous Plackett-Burman design. The objectives of this present work were to locate optimum levels of these process parameters, and to find out interactions among them for enhancement of the yield of extracellular polysaccharide and mycelium biomass. By solving the regression equation and also by analyzing the response surface contour plots, the optimal process conditions were determined: under conditions of temperature, 28.07℃; cultivation time, 8.79 d and volume of medium, 68.51 mL, the prediction of extracellular polysaccharide content (EPC) by Pholiota squarrosa AS 5.245 was 1062.69 ?g per milliliter of fermentation liquor. While cultivation temperature, time and volume of medium were 27.60℃, 9.42 d and 54.20 mL respectively, the mycelium biomass expressed as dry cell weight (DCW) was 11.32 mg?mL -1. In order to simultaneously obtain the maximum yield of EPC and DCW, the above conditions would be located at 27.62℃, 9.19 d and 64.10 mL. In these conditions, the maximum predicted yield of EPC and DCW were found to be 1050.64 ?g?mL -1 and 11.10 mg?mL -1, respectively. These predicted values were also verified by validation experiment.
