Objective To study the efficacy of insulin pump therapy for type 2 diabetes and its impact on quality of life.Methods 60 patients with type 2 diabetes were selected and divided into A group and B group according to a random number table,30 cases in each group.The patients of B group were given conventional therapy,and which of A group was treated with insulin pump.The fasting plasma glucose,0.5h fasting blood glucose and 2h postprandial blood glucose were measured and compared before and after treatment,the quality of life was evaluated by quality of life scale(QOL),the QOL score before and after treatment between two groups was compared.Results The fasting plasma glucose,0.5h fasting blood glucose and 2h postprandial blood glucose of A group after treatment were (5.69 ±0.19)mmol/L,(5.28 ± 1.03) mmol/L and (7.31 ±2.14) mmol/L,respectively,which were significantly lower than (6.72 ± 2.04) mmol/L,(6.39 ± 1.69) mmol/L and (9.72 ± 1.57) mmol/L of B group (t =9.798,10.023,9.971,P =0.035,0.027,0.032) ; The QOL score of the group A was (78.4 ± 0.8) points,which was significantly better than that before treatment (t =9.064,P =0.023),and better than that of group B (t =10.853,P =0.019).Conclusion Insulin pump has better clinical efficacy in the treatment of type 2 diabetes compared with conventional therapy,it can effectively control blood sugar and improve the quality of life of patients.

Objective To analyze the onset, clinical manifestation, causation, complications of pediatric uveitis. MethodsOne hundred and two patients with uveitis under 16 year-old were retrospectively studied. They visited the clinic in Peking University First Hospital from November 1979 to December 2008. Their age ranged from 2.5 to 16 years old, with a mcan of 11.9 years. Routine exam was carried out, including visual acuity, slit lamp, fundus, and laboratory workup. The diagnosis and classification were made by the anatomic location according to the standard of The International Uveitis Working Group. The data of disease history, age of onset, manifestation, recurrence, causation, systemic diseases, complications, and lab examination were analyzed. Results A total of 102 patients (170 eyes)with pediatric uveitis were included in this study, 68 patients (66.6%) were bilateral cases. Anterior uveitis represented in 38 patients (37.3% ), intermediate uveitis in 19 (18.6%), posterior uveitis in 10 (9.8%),and panuveitis in 35 (34.3%). The disease duration was from five days to 2.4 years, with a mean of 3.6 months. The follow-up time was two weeks to more than ten years. The first three causes of pediatric uveitis were juvenile idiopathic arthritis, Vogt-Koyanagi Harada disease, and Behcet's disease. 36 patients were found with complications, and among them 19 had complicated cataract, seven had secondary glaucoma, five had corneal band dystrophy, 12 had iris synechia (both anterior and posterior), one had retinal detachment, two had eye atrophy, and one patient with juvenile idiopathic arthritis had bilateral femoral head necrosis because of the use of steroid and hip joint was replaced. There were ten children suffering more than two complications. Conclusions Pediatric uveitis is a possible blindness disease with variety of etiology and manifestations, and tends to cause complications. Early and special attention must be taken to avoid serious consequences.

This study was aimed to explore the methodology regarding culture, proliferation and purification of adipose-derived stromal cells (ADSCs), and to study their biological characteristics. ADSCs were obtained using type I collagenase digestion method. Cell growth was observed, and cell viability were detected under different digestion period by MTT. The ADSCs were then identified and induced. The results showed that adherent cells digested by type I collagenase for 60 min had a strong proliferation capability. After the induction of different inducers these adherent cells could differentiate into nerve cells and fat cells. The best digestion period was proved to be of 60 minutes in the experiment. The results indicate that stem cells with multilineage differentiation ability could be separated from adipose tissue, namely ADSCs.
