Objective To investigate the association of cytotoxic T lymphocyte associated antigen 4(CTLA 4) gene polymorphism with type 1 diabetes in Chinese Han population.Methods The A/G phenotype at position 49 of the CTLA 4 gene exon 1 was determined by polymerase chain reaction restriction fragment length polymorphism(PCR RFLP)method in 33 typical type 1 diabetes patients,57 latent autoimmune diabetes in adults(LADA) patients and 84 healthy control subjects of Chinese Han.Results The frequency of the CTLA 4/G 49 phenotype was significantly higher in type 1 diabetes patients than in control subjects(55.6% vs 36.9%, respectively, P =0.0005),but there was no significant difference between typical type 1 DM and LADA groups. Neither the presence nor the absence of G 49 allele influenced the occurrence of islet autoantibody(ICA) and glutamate decarboxylase antibody(GADAb).Conclusion The polymorphism of CTLA 4 gene exon1 confers susceptibility to type 1 diabetes. This association is independent of ICA and GADAb.

Objective To investigate the clinical effectiveness of autologous platelet-rich-plasma (PRP) combined with iliac autograft in reconstruction of bony defective nonunion of humeral condyle.Methods The 27 patients who had been admitted to our department from January 2004 to June 2015 for bony defective nonunion of humeral condyle were analyzed retrospectively.Of them,15 underwent reconstruction with PRP combined with iliac autograft (experimental group) and 12 reconstruction with only iliac autograft (control group).The preoperative demographic data of the 2 groups were not significantly different (P ＞ 0.05).The 2 groups were compared in terms of operation time,hospital stay,bony union time,range of motion of the elbow,and modified Cassebaum scoring.Results The patients were followed up for 12 to 90 months (average,24.6 months).No such complications were observed as displacement of bone blocks,loosening or breakage of implants,re-nonunion,malunion,delayed ulnar neuritis,or olecranon nonunion.There were no statistic differences between the 2 groups regarding operation time,hospital stay,range of motion of the elbow and modified Cassebaum scoring (P ＞ 0.05).The clinical healing time (4.2 ± 1.3 months) and bony healing time (4.8 ± 1.4 months) for the experimental group were significantly shorter than for the control group (6.0 ± 1.1 months and 6.2 ± 1.0 months,respectively) (P ＜ 0.05).Conclusion Autologous PRP combined with iliac autograft can speed up the healing of bony defective nonunion of humeral condyle,promoting functional recovery of the elbow.

Objective To evaluate the efficacy of intra-aortic balloon pump (IABP) on elderly patients with acute myocardial infarction (AMI) combined with cardiogenic shock (CS).Methods Among 62 elderly patients with AMI plus CS undergoing percutaneous coronary intervention (PCI),32 patients received IABP before PCI (IABP group) and 30 patients did not (control group).Diastolic blood press ure(DBP),mean arterial pressure (MAP),heart rate,cardiac index (CI),and ejective fraction before and 2 weeks after PCI in the two groups were observed.The short-and long-term therapeutic effects were compared between the two groups.Results The DBP,MAP and CI were higher and heart rate was lower in IABP group than in control group within 24 h after IABP [(64.4± 11.1) mmHg vs.(37.8±15.1) mmHg,(71.4±8.3) mmHg vs.(43.0±10.5) mmHg,(2.98± 0.33) L· min-1 · m-2 vs.(1.99±0.29) L· min-1 · m-2,(90.7±18.7) /min vs.(130.2±50.1)/min,t=7.97,11.83,12.51,4.16,all P=0.000].Two weeks after IABP,LVEF was significantly improved in IABP and control groups as compared with pre-IABP [(46.4±7.2)％ vs.(35.2± 7.2) ％,(39.1±6.8) ％ vs.(33.8±6.7) ％,both P＜0.01],and heart function was improved more significantly in IABP group than in the control group (t=3.91,P=0.000).Death tolls during hospitalization and after leaving hospital,and recurrence of AMI had no significant differences between the two groups (2 cases vs.4 cases,3 cases vs.8 cases,6 cases vs.10 cases,x2 =0.89,3.17,1.72,P=0.346,0.075,0.190).Conclusions IABP can improve the cardiac function in elderly AMI patients with CS after PCI.

OBJECTIVE: To systematically evaluate the application of microcapsuled cell or encystation materials for treating diabetes mellitus at hone or abroad in recent years.METHODS: A computer-based online search of PubMed database was undertaken to identify related articles about the microcapsulated cell or encystation material for treating diabetes mellitus published from 1980 to 2009 by using the key words of "microcapsulation, islet, transplantation" in English. Meanwhile, we search CNKI for relevant articles published between 1999 and 2009 with the same key words in Chinese. The related randomized, controlled, and clinical studies were collected according to conclusion and exclusion criteria.RESULTS: Among 25 articles, there were 46 patients with type I diabetes mellitus, 106 rats, 20 pigs, and 25 monkeys. The experimental results showed that both the microcapsulated islets and non-microcapsulated islets could secrete insulin and decrease blood glucose level. The normal blood glucose level with microcapulated islets could be maintained for a long time.Thus, microcapsule had a great immune isolation reaction.CONCLUSION: After transplantation, microencapsulated islet cells could improve and adjust abnormal glycometabolism of patients with diabetes mellitus; furthermore, the immunoisolation effect of microcapsule could eliminate or relieve the immunological rejection of receptors to allograft or xenograft, while it could also relieve or eliminate dependence on immunosuppressive drugs. Appropriate material of microcapsule, reasonable process, advanced equipment, advanced separation and purification technologies of islet, and suitable site for transplantation could improve the function of artificial islet cell, enhance the anti-machinery and chemical strength of microencapsuiated islet, improve biocompatibility, and prolong survival time.
