Objective To evaluate the efleet of continuous subcutaneous insulin infusion (CSII)combined with mefformin hydroehloride( Met H)on type 2 diabetic patients. Methods 240 patients with type 2 diabetes melli-tus (T2DM) were divided into 3 groups randomly: CSII combined with Met H ( A group: n=80) ; simple CSII ( B group:n=80) ; multiple deliver insulin (MDI) ( C group: n=80). The levels of blood glucose, HbA1 e, therapeutic time, a-mount of insulin, Fins ,C-P, HOMA-IR and IAI were compared among them before and after 10d of treatment. Results GroupA, B eornpared with group C, the levels of HbA1 e significantly deeroased in other two groups [ ( 8.0±3.2)%vs. (6.9±1.4)% and(7.0±1.2)% ] (aU P<0.05),so did the therapeutic time[(6.0±1.9)d vs. (3.0±1.4) and(3.5±1.5) d] and insulin dose[ (55.0±17.0) U/d vs. (38.0±15.0) U/d and(45.0±16) U/d] (all P<0.05). The insulin dose was much less in group A than in group B. Versus group B and C,the HOMA-IR of group A (0.8±0.3 vs. 1.5±0.4 and 1.6±0.4)decreased(P<0.05) ,and IAI(-2.0±4.3 vs. -3.6±4. 2 and -4.1±4.3) increased (all P<0.05), without the function impairments of heart, liver or kidney. Conclusion CSII in combi-nation with mefformin hydreehloride can significantly enhance the treatment effect of the patients with type 2 diabetes mellitns; reduce blood glucose and HbA1 e, improve insulin resistenee,lessen insulin need.

Objective To explore the application value of susceptibility weighted imaging (SWD) in the Parkinson disease (PD) diagnosis by analysis the changes of brain iron content of the basal ganglia and red nucleus.Methods Totally 56 cases of patients with PD and 40 cases of normal control group were diagnosed by SWI with the 3.0 T magnetic resonance imaging system,the corresponding phase image by using SWI processing software was obtained,the signal values of the various regions of the brain basal ganglia and red nucleus were measured and compared.Results In comparison of PD group with normal control group,the signal values showed differences in caudate (0.05±0.01 vs.0.04±0.01,t=1.991),putamen(-0.42±0.13 vs.-0.25±0.07,t=2.544) and globus pallidus(-0.23± 0.07 vs.-0.11±0.02,t=2.893) (all P＜0.05).Conclusions Determining the iron deposition signal of the various regions of the brain basal ganglia by SWI is valuable in the clinical diagnosis of Parkinson's disease.

Autophagy is a dynamic process which subcellular membranes undergo morphological changes that lead to the degradation of cellular cytoplasmic organelles and macromolecules.It is regulated by themammalian target of rapamycin ( mTOR ) -dependent or -independent signaling pathways.It has been demonstrated that autophagy is induced or inhibited in various tumor cells,and it is closely related with cell survival and drug resistance.Because of the complex relationships with cell death,the roles of autophagy in cancer developnent,treatment,and drug-resistance are not the same,and thus controlling autophagy properly may become one of new means of cancer therapy.

Most patients with allergic conjunctivitis in children are vernal keratoconjunctivitis.Dry eye accompanied with al- lergic conjunctivitis in children is correlated with the decline of tear film stability.However,tear film stability decline is correlated with eosinophilic activation and concomitant release of inflammatory mediators.Moreover,conjunctival epithelial,goblet cells and tear film are damaged,then dry eye occur.Main symptom of dry eye in children is twinkling frequency increasing,followed by eye itch,eye red and photophobia.When allergic conjunctivitis in children is diagnosed,dry eye should be considered at the same time.Proper manage- ment for those allergic conjunctivitis can decrease ocular surface damages.

Objective To explore the effect of ischemia-reperfusion injury on the retinal functions of rats. Methods Seventy Wistar rats were selected, 20 of which were selected randomly and divided into two groups (control group and single-irrigated group). The rats were anesthetized and their anterior chambers of the right eyes were cannulated with a 7-gauge needle connected to a reservoir containing ringers balanced salt solution, which was maintained at the same level of the eye for 1 hour. After that, ERG was recorded in both eyes of all rats. All the left rats were divided randomly into 10 groups and they were treated as the single-irrigated group. Retinal ischemia was induced by raising the reservoir to a height of 150 mm Hg. One hour later except the single ischemia group, all of the groups resumed perfusion after 3,6,12,and 24 hours and 3,5,7,14,and 21 days separately. ERG was recorded in both eyes of all rats. Results There was no difference in the results of ERG between left and right eyes in either the control group or the single-irrigated group. All the waves of ERG vanished in the single-ischemia group after 1 hour. In the ischemia-reperfusion groups, the waves of ERG partly recovered and the amplitude reduced persistently and progressively. Conclusion Ischemia-reperfusion injury may affect the function of the retina persistently and progressively.

Scaffold is one of the key elements required for tissue engineering. Porous scaffolds have several special advantages for muscle tissue engineering, and they are beneficial to cell survival, myogenic differentiation, and vascular ingrowth. The performance of porous scaffolds is closely related to the property of the biomaterials used. Additionally, the pore size and porosity may affect cell adhesion, proliferation, and differentiation. This review focuses on the application of porous scaffolds in muscle tissue engineering, including their categories, application, and advantages.

Aim To investigate the protective effects of omapatrilat on human umbilical vein endothelial cells (HUVECs) injury induced by angiotensin Ⅱ (AngⅡ) in culture. Methods Cultured HUVECs were randomly divided into 4 groups:①control; ②AngⅡ;③omapatrilat and ④AngⅡ+omapatrilat. Lactate dehydrogenase (LDH) leakage was evaluated by spectrophotometer and cell cycle by flow cytometry (FCM); Nitric oxide (NO) was measured by colorimetry and endothelin-1 (ET-1) by radioimmunoassay. Results 10 -7 mol?L -1 AngⅡ significantly increased LDH leakage and ET-1 release, and this increase was inhibited by omapatrilat (10 -6 mol?L -1). Omapatrilat promoted HUVECs proliferation and NO release. Conclusion Omapatrilat can protect human umbilical vein endothelial cells injury induced by angiotensin Ⅱ in culture, suggesting that it may play an important role in prevention and treatment of vascular diseases.

0.05). Logistic multiple regression analysis showed T242 allele, body mass index, fasting blood glucose, HbAlc, Homa-IS, systolic blood pressure were risk factors of type 2 diabetic nephropathy. Conclusions p22phox C242T gene polymorphism is associated with diabetic nephropathy in Shanghai people. p22phox subunit T allele mutation is pnobabaly one of predisposing genes of type 2 diabetic nephropathy, and p22phox A640G gene polymorphism is not associated with diabetic nephropathy in Shanghai people. T242 allele, fasting blood glucose, HbAlc, Homa-IS, systolic blood pressure are risk factors of type 2 diabetic nephropathy.
