[Summary] Cardiovascular disease ,diabetic nephropathy and diabetic retinopathy are common complications of diabetes ,and are the significant reason of cardiovascular mortality ,end-stage renal disease ,and blindness in adults patients with type 2 diabetes mellitus. At present, the researche on the pathogenesis of diabetic complications mainly focus on oxidative stress and chronic inflammation. In addition, a large number of studies have pointed out that bilirubin has antioxidant and anti-inflammatory effects. Therefore, bilirubin and diabetic complications are closely linked.

Objective To observe the clinical effect by using insulin detemir therapy in children and adolescents with type 1 diabetes mellitus(T1DM).Methods Thirty children and adolescents with T1DM were divided into 2 groups to receive Humulin R and Determir(observation group,n =15) or Humulin R and neutral protamine hagedorn (NPH) (control group,n =15)insulin therapy.Daily insulin dose,glycemic variability,incidence of non-severe and severe hypoglycemia events after the institution of insulin therapy were collected.Results The daily doses of insulin were (1.16 ± 0.30) U/kg in the observation group and(1.21 ± 0.35) U/kg in the control group,respectively.There was no clinically important change between 2 groups(t =0.526,P ＞ 0.05).Within-subject variation in fasting plasma glucose was significantly lower in observation group(29％)than that in control group(65％) (t =5.296,P ＜0.01).One case of severe hypoglycemia event occurred in the observation group,but 5 cases occurred in the control group(t =4.863,P ＜ 0.0l).Two cases of nocturnal hypoglycaemia(22:00-7:00) events occurred in the observation group,7 cases occurred in the control group(t =4.506,P ＜ 0.01).Conclusions Institution of insulin detemir therapy is associated with low within-subject variation in fasting plasma glucose and decreased rates of severe and nocturnal hypoglycemia while dose of insulin did not increase.This makes insulin detemir a valuable new tool for the treatment of children and adolescents with T1 DM.

Objective It was reported that p53 apoptotic peptide (N37) could inhibit p73 gene through being bound with iASPP, which could induce tumor cell apoptosis. To further explore the function of N37, we constructed the cloning plasmid of DNA fragment encoding p53 (N37) apoptotic peptide by using DNA synthesis and molecular biology methods. Methods According to human p53 sequence from the GenBank database, the primer of p53(N37) gene was designed using Primer V7.0 software. The DNA fragment encoding p53 (N37) apoptotic peptide was amplified by using self-complementation polymerase chain reaction (PCR) method and cloned into the pGEM-T Easy vector. The constructed plasmid was confirmed by endonuclease analysis and sequencing. Results The insertion of objective DNA fragment was confirmed by plasmid DNA enzyme spectrum analysis, p53 (N37) gene was successfully synthesized chemically in vitro. The sequencing result of positive clone was completely identical to the human p53(N37) sequence in GenBank using BLAST software (http://www. ncbi. him. nih. gov/cgi-bin /BLASTn). Conclusion The cloning of DNA fragment encoding p53(N37) apoptotic peptide was constructed by using DNA synthesis and pGEM-T Easy cloning methods. With the constructed plasmid, we could further investigate the function of N37 peptide.

Objective:To analyze the diagnosis and treatment of 1 case of primary bone marrow diffuse large B cell lymphoma (DLBCL),and to provide the reference for its dignosis and treatment. Methods:Combined the medical history and other auxiliary examination results, the possibility of diagnosis of primary bone marrow lymphoma (PBML)was suspected. Bone marrow biopsy and immunohistochemistry were carried out for diagnosis, and R-CHOP (rituximab, cyclophosphamide,doxorubicin,vincristine,and prednisolone) was selected as the chemotherapy scheme. Results:The diagnostic basis of the case was in accordance with the diagnostic standard of PBML.According to the results of immunohistochemical staining,it was classified as the DLBCL subtype. Then the patient received 6 cycles of R-CHOP immune chemotherapy. Complete remission of bone marrow cell morphology was gained after the first cycle of R-CHOP treatment,and the patient was treated for another five cycles and the complete remission was retained in 3 months of follow up after drug withdrawal. Conclusion:Bone marrow biospy and immunohistochemistry have the unique diagnostic values for primary bone marrow DLBCL,and the regimens containing rituximab may provide a ideal efficacy during short term observation.
