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.

Objective To explore the clinical manifestations of toxic epidermal necrolysis(TEN) and its rare pulmonary complications.Methods Clinical symptoms,treatment and prognosis of 1 child with TEN caused by carbamazepine were analyzed.Radiological images were reviewed to evaluate the manifestations and the outcome of chronic pulmonary complications associated with TEN.Results The patient had high fever shortly after a dosage increment of carbamazepine.A confluent erythematous exanthema developed rapidly into painful blistering with skin erosion,denudation and involvement of conjunctive and oropharyngeal mucosa.The diagnosis of TEN was made.The mucocutaneous damage was gradually recovered with steroid plus intravenous immunoglobulin for 3 weeks.However,the patient presented with respiratory failure in the recovery phase of TEN.The computer tomography revealed pulmonary bullae and pneumothorax in the right lung.Lung parenchyma was squeezed and pulmonary bullae ruptured with pneumothorax and atelectasis,which were absorbed gradually through thoracic drainages.The patient′s lung function and pulmonary bullae were partly improved during a 7-month follow-up.Conclusions TEN is a severe form of blistering skin di-sease which is characterized by an extensive loss of epidermis and mucous membrane.Chronic pulmonary complications may occur in recovery phase of TEN.Pulmonary bullae,which might be caused by mucous damage and respiratory obstruction,is a rare complication of TEN.

Xiao Zhi Ling Injection is a Chinese herbal aqueous solution of praeparatum which is mainly made of gallnut and alum, it can make a " strengthening body resistance " treatment in polytype tumors, mainly through promoting apoptosis of tumor cells, destructing tumor cells, inhibiting tumor growth, enhan-cing immunity of organism and so on, the clinical effect is certain, with the development of theory and tech-nology in tumor molecular biology, it has become the core of future research that how to further explore Xiao-Zhi-Ling injection to promote tumor cell apoptosis by impacting on related genes, and its lucubrate inevitably provide new hope in gene therapy of cancer.

BACKGROUND: Epidural resistance materials are an approach to prevent the epidural scar adhesion after laminectomy. A composite membrane of mechanical separation and fibroblast inhibition is promising to be widely studied.OBJECTIVE: To prepare the interferon (IFN)/poly (lactic-co-glycolic acid) (PLGA) and chitosan/PLGA composite membranes, and to observe their effects on preventing epidural scar adhesion after laminectomy in rabbits.METHODS: L2 laminectomy was performed in 120 rabbits, which were randomly and evenly divided into six groups. The control group received nothing on epidurals. In the autologous free fat group, the exposed dura was covered with subcutaneous fat. In the sodium hyaluronate group, 1 mL sodium hyaluronate was dripped onto the dura. In the PLGA, chitosan/PLGA, and IFN/PLGA groups, the exposed dura was covered with one of the three membranes at a sufficient size. The animals were sacrificed at 2, 4, 6, 8 weeks postoperatively. The scar formation and adhesion to the dura in L2 laminectomy sites were observed and scored by gross observation. At 4 weeks postoperatively, fibroblast ultrastructure was observed through the use of transmission electron microscope.RESULTS AND CONCLUSION: Widespread scars formed in the control group. The scars in the autologous free fat and PLGA groups were less compared with the control group, but there was no significant difference between these two groups. In the early stage, the scars in the sodium hyaluronate group were obviously less compared with the autologous free rat and PLGA groups, while in the later period, the difference between them was not significant, but the results from the sodium hyaluronate group were still better compared with the control group. The scars and slight adhesion to the dura were observed in the chitosan/PLGA and IFN/PLGA groups. The effect of preventing scar adhesion in these two groups was remarkably superior to that in the other groups, but there was no significant difference between these two composite membrane groups. At 4 weeks postoperatively, fibroblast morphology and function in the control, autologous free rat, and PLGA groups were better than those in the chitosan/PLGA and IFN/PLGA groups. Chitosan/PLGA and IFN/PLGA composite membranes are effective materials to prevent epidural scar adhesion after laminectomy.

Objective to evaluate the clinical efficacy and safety of ADSCs infusion in patients with type 2 diabetes mellitus(t2DM). Methods Autologous ADSCs were cultured and identified. totally 48 cases of type 2 diabetes patients were divided into two groups:24 cases in A group re-ceived ADSCs and conventional treatment,while the other 24 cases in B group received conventional treatment. With 15 months′follow-up,FPG,2h-PGh,HbA1c,FC-P,AUCC,insulin medication changes and security on post-treatment 3,6,12 and 15 months were calculated. Results the AD-SCs which cultured met the clinical application of standards. FPG,2h-PGh and HbA1c in both groups were significantly decreased,and the values in A group were more impressive than B. there were significant improvement in FC-P,AUCC and insulin of A group compared with B group. there was not treatment related adverse events. Conclusion the clinical data demonstrate that the treatment with ADSCs can improve metabolic control and beta cell function in patients with t2DM. Moreover,the safety of the treatment method was considerable.
