Postpartum inferior vena cava (IVC) thrombosis is a rare, but potentially life-threatening disorder. Here we reported one case of the youngest woman to date who presented with massive IVC thrombus extending from deep veins of the right leg to the level of the 11th thoracic vertebra, associated with asymptomatic pulmonary embolism.

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.

ABSTRACT:Objective To investigate the effect and mechanism of anthocyanin on hepatic ischemia reperfusion injury in rats .Methods Totally 30 SD rats were randomly divided into sham group ,model group and anthocyanin group (n=10 in each) .Hepatic ischemia was constructed in model group and anthocyanin group by ligating left middle lobe of liver vascular branches for 90 min . Anthocyanin was administered at 90 min before ischemia by intraperitoneal injection at the concentration of 100 mg/kg for rats in anthocyanin group .Rats in model group and sham group were injected with the same dosage of normal saline at the same time .Serum and liver tissues were collected at 4 h after reperfusion by putting the rats to death .The expressions of ALT ,AST ,IL‐6 ,IL‐1βand TNF‐αin the serum were examined by ELISA .The pathological changes of liver tissue were evaluated by HE .The mRNA levels of IL‐6 ,IL‐1βand TNF‐αwere measured by RT‐PCR .The content of MDA was examined by TBA . The activities of CAT ,GPx and SOD were evaluated by xanthine oxidase method and the expression of p‐JAK2 ,p‐STAT3 ,JAK2 ,STAT3 and P53 were measured by Western blot .Results Compared with those in the sham group ,the activities of ALT and AST ,the expressions of p‐JAK2 ,p‐STAT3 ,P53 ,IL‐6 ,IL‐1β,TNF‐α and the content of MDA as well as the pathological changes of the liver in model group were significantly increased .

Objective To compare effects of compound Xueshuantong capsule and benazepril on inflammatory cyto-kines in type 2 diabetic patients with early diabetic nephropathy (DN), and its therapeutic mechanism thereof. Methods Ninety-four patients with type 2 diabetes were divided into diabetes without albuminuria group (DM,n=24) and early DN group (DN,n=70). DN group was then divided into three subgroups:group A (n=24) treated by benazepril alone, group B (n=22) treated by compound Xueshuantong capsule and group C (n=24) treated by compound Xueshuantong capsule combined with benazepril for 3 months. Levels of fasting blood glucose, glycosylated hemoglobin, serum creatinine, blood urea nitro-gen, lipid profiles, fibrinogen and urinary albumin excretion rate (UAER) were examined before and after treatment. The se-rum levels of hypersensitive c-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor-α(TNF-α) were determined as well. Results The serum levels of hs-CRP, IL-6 and TNF-αwere significantly higher in DN group than those of DM group (P<0.01). After treatment, the serum levels of UAER, hs-CRP, IL-6 and TNF-αwere significantly re-duced in groups A, B and C compared with those before treatment (P<0.01), and which were decreased more significantly in group C. The levels of blood lipids and fibrinogen decreased obviously in group C compared with those of group A and B ( P<0.01). Conclusion Compound Xueshuantong capsule combined with benazepril not only can improve the blood fat and high coagulation state in patients, but also impossibly retard the development of early DN through decreasing serum concen-trations of hs-CRP, IL-6 and TNF-αand inhibiting inflammatory reaction.
