BACKGROUND:Adipose-derived stem cells discovered recently are a new kind of adult stem cells, and have a strong multi-differentiation capacity. However, there are rare studies concerning in vivo osteogenic capacity of adipose-derived stem cells.
OBJECTIVE:To investigate the effect of adipose-derived stem cells combined with gelatin sponge on repairing bone defects.
METHODS:Adipose-derived stem cells from rabbit inguinal fat pads were isolated and cultured, and then
induced using an osteogenic medium containing bone morphogenetic protein 2 fol owed by injection of gelatin sponge. Radial defect models of rabbits were prepared. Compound of adipose-derived stem cel s and gelatin sponge was implanted into the lesion side, while gelatin sponge alone was implanted into the contralateral side. Rabbits were kil ed at weeks 6 and 12 after bone defect repair for X-ray examination, CT scan, and hematoxylin-eosin staining.
RESULTS AND CONCLUSION:Lane-Sandhu X-ray and Lane-Sandhu histological scores after compound implantation were significantly higher than those after repair with gelatin sponge alone. It indicates that
adipose-derived stem cel s combined with gelatin sponge can promote bone defect healing of rabbits, showing an obvious osteogenic capacity in vivo.

Objective To study the effects of angiotensin Ⅱ (AngⅡ) on insulin signal transduction pathway in skeletal myoblast of L6 rats,and further to explore the possible mechanism of AngⅡ on glucose utilization.Methods Myoblast cells of L6 rats were cultured and induced to differentiate.They were divided into 4 groups according to different treatment by AngⅡ or JAK2-PKA inhibitor H89:normal control group ( NC group),insulin group,insulin + AngⅡ group and insulin + AngⅡ + H89 group.Expression of IRS1 and GLUT4 mRNA was detected by RT-PCR.Expression of IRS1,Ptyr-IRS1 and GLUT4 (total and membrane protein) were detected by Western blot.Results The difference of GLUT4 mRNA expression in the 4 groups detected by RT-PCR had no statistical significance(P ＞ 0.05).The difference of IRS1 mRNA expression among the latter 3 groups had no statistical significance(P ＞ 0.05),however,IRS1 expression in the latter 3 groups was higher than that in NC group(P ＜ 0.05).Western blot results showed expression of IRS1,Ptyr-IRS1 and GLUT4 (membrane protein)was higher in the latter 3 groups than in NC group(P ＜0.05).The difference of IRS1 expression among the latter 3 groups(P ＞ 0.05 ) and GLUT4 (total protein) expression among the 4 groups had no statistical significance (P ＞ 0.05).The expression of of ptyr-IRS1 and GLUT4 membrane protein in Ins + AngⅡ + H89 group was much higher than that in Ins + AngⅡ group,and lower than that in insulin group(P ＜0.05).Conclusion AngⅡ inhibits IRS1's tyrosine phosphorylation and GLUT4's transfer from cytoplasm to plasma membrane in skeletal muscle cells through JAK2-PKA signaling pathway,and therefore induces insulin resistance.

Objective To investigate the relevant factors of type 2 diabetes mellitus (T2DM) with cerebral infarction (CI).Methods A total of 323 patients with T2DM from February 2012 to March 2017 in Inner Mongolia medical university affiliated hospital were included in this study.150 patients with T2DM and CI were considered as experiment group,173 cases of T2DM without CI were considered as control group.The clinical data of two groups were analyzed.Results The history of diabetes,smoking and hypertension were longer in experiment group than in control group (P＜ 0.05).The patients in experiment group had higher fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total triglycerides (TG),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),non-HDL-C,homocysteine (Hcy),fibrinogen (FIB),retinol binding protein 4 (RBP4) and lower HDL-C,apolipoprotein A1 (ApoA1) than the patients in control group (P＜ 0.05).Multiple-factor logistic regression analysis showed that long-term smoking,long history of hypertension,high TG,high LDL-C,high non-HDL-C,high Hcy,high RBP4,low HDL-C and low ApoA1 were risk factors for CI in patients with T2DM (P＜0.05).After adjusting common variables (diabetes history,hypertension history,smoking history,HbA1c,TG,TC),multiple-factor logistic regression analysis showed that LDL-C,non-HDL-C,Hcy,RBP4 were risk factors for CI in T2DM (P＜0.05).HDL-C and ApoA1 were protective factors for CI in T2DM (P＜0.05).Conclusion The risk factors for CI in patients with T2DM include long-term smoking,long hypertension history,high HbA1c,high TG,high LDL-C,high non-HDL-C,high Hcy,high RBP4,low HDL-C and low ApoA1.Patients should be advised to quit smoking,control blood glucose and blood pressure,and regulate blood lipid levels.

Objective:This was a retrospective study to compare the serum 25-hydroxy vitamin D [25(OH)D], retinol binding protein 4(RBP-4) and other clinical data in type 2 diabetes mellitus (T2DM) patients with or without diabetic nephropathy (DN) and to explore the clinical significance of these indicators in DN.Methods:1946 T2DM patients were enrolled in this study. The T2DM patients were divided to group with diabetic nephropathy (DN group) and without diabetic nephropathy (NDN group). According to the urine albumin to creatinine ratio (UACR), DN patients were further divided into microalbuminuria subgroup (UACR 30~300 mg/g) and massive proteinuria subgroup (UACR> /g). Clinical characteristics including serum 25(OH)D, RBP-4 and other biochemical indicators were collected.Results:Compared with NDN group, DN group showed longer disease duration, older age and higher levels of HbA1c, RBP-4, hs-CRP, TC and TG; 25(OH)D and HDL-C in DN group were lower than those in NDN group ( P<0.05). Within DN group, massive proteinuria subgroup showed higher RBP-4, younger age and lower 25(OH)D and HDL-C than microalbuminuria subgroup ( P<0.05). After adjusted for age, gender and disease duration in DN, partial correlation analysis showed that 25(OH)D is positively correlated with eGFR, and negatively correlated with RBP-4 and UACR ( P<0.05). UACR is positively correlated with RBP-4 and TC, and negatively correlated with eGFR (all P<0.05). eGFR is negatively correlated with RBP-4, TC and UACR (all P<0.05). Multivariate logistic regression showed that disease duration, HbA1c, RBP-4 and hs-CRP are risk factors for DN, and 25(OH)D is the protective factor for DN. Conclusions:Decreased 25(OH)D and increased RBP-4 are associated with increased DN risk in T2DM patients, and also associated with exacerbated albuminuria and deteriorated renal function in DN patients. There is a negative correlation between 25(OH)D and RBP-4 in DN. Therefore, it is necessary to strengthen the monitoring of serum 25(OH)D and RBP-4 and enhance vitamin D supplementation in T2DM patients to prevent the occurrence and delay the progression of diabetic nephropathy.

Adriamycin resistance in HCC seriously hinders the treatment of patients, it is necessary to investigate the mechanisms. Autophagy is involved in adriamycin resistance and JNK2 is related to autophagy. However, whether JNK2 inducing drug resistance though autophagy is unknown. GL-V9, a new synthesized flavonoid derivative, has been proved of its anti-tumor effects. The aim of the study is to explore the role of JNK2-related autophagy on adriamycin-induced drug resistance and the effects of GL-V9 on reversing adriamycin resistance. We concluded that JNK2 played an important role in drug resistance induced by adriamycin. The high expression of JNK2 activated protective autophagy in Hep G2-DOXR cells under non-stress condition, which protected cells from drug attacking. Furthermore, we found that GL-V9 reversed adriamycin resistance by blocking the JNK2-related protective autophagy in HCC.
