1.Expression of vascular endothelial growth factor in the treatment of diabetic foot using bone marrow mesenchymal stem cell transplantation
Chinese Journal of Tissue Engineering Research 2013;(40):7169-7174
BACKGROUND:Bone marrow mesenchymal stem celltransplantation has been confirmed to have excellent effect on the treatment of diabetic foot.
OBJECTIVE:To assess the therapeutic effect of bone marrow mesenchymal stem celltransplantation on diabetic foot ulcers and the expression of vascular endothelial growth factor.
METHODS:Literatures concerning the effect of bone marrow mesenchymal stem celltransplantation on foot diabetic and expression of vascular endothelial stem cells were retrieved. Articles that met the criteria were analyzed in depth. Here, we analyzed the experimental research and clinical application of bone marrow mesenchymal stem cells in the treatment of diabetic foot. In experimental studies, rat models of diabetic foot ulcers were established and subjected to bone marrow mesenchymal stem celltransplantation to observe wound healing of ulcers and analyze the expression of vascular endothelial growth factor. In clinical research, the fol ow-up was conducted in diabetic foot patients undergoing bone marrow mesenchymal stem celltransplantation to observe the wound healing of ulcers and adverse reactions.
RESULTS AND CONCLUSION: Experimental studies have shown that bone marrow mesenchymal stem celltransplantation is better than conventional treatment in the treatment of diabetic foot ulcers, but the healing of diabetic foot ulcers is stil slower than that of normal ulcers. After celltransplantation, the expression of vascular endothelial stem cells is elevated but stil lower than that in the normal ulcer controls. Clinical studies have shown that for patients with diabetic foot ulcers, the ulcer wound can be healed after bone marrow mesenchymal stem celltransplantation, as wel as there are no cardiovascular and cerebrovascular diseases, liver and kidney damage and changes in bleeding and coagulation time.

3. An experimental study of pioglitazone in treating vascular dementia
Academic Journal of Xi'an Jiaotong University 2010;22(3):179-182
Objective: To compare the therapeutic effects of different doses of pioglitazone, a kind of peroxisome proliferator-activated receptor γ (PPARγ) agonist, on vascular dementia and explore how pioglitazone affects cerebral ischemia. Methods: Modified Pulsinelli's vessel ligation was used to establish a vascular dementia model in rats. Recognition, learning and memory were evaluated by Morris's water maze test. Immunoenzyme staining was used to determine the number of nerve cells. Immunofluorescence double-staining was used to examine the expression of PPARγ/nerve cells and PPARγ/astrocytes in different groups. Results: Both in pioglitazone groups and sham-operation group, the latency was reduced significantly compared to that in control group (P < 0.01). Sham-operation group had the largest number of neurons in the cortex, followed by low-dose pioglitazone group and high-dose pioglitazone group, and control group came last. Compared with control group, pioglitazone groups had more PPARγ expression in nerve cells, and the fluorescence intensity of PPARγ was stronger. Conclusion: Pioglitazone can induce the expression of PPARγ in neuron endochylema and astrocyte endochylema to protect nerve cells, and then to improve spatial learning and memory function in VD rats.

5.The correlation between human leukocyte antigen-DRB1 alleles and anti-neutrophil cytoplasmatic antibodies in Han and Uygur ulcerative colitis patients in Xinjiang region
Chinese Journal of Digestion 2012;32(11):750-753
Objective To study the correlation between human leukocyte antigen (HLA)-DRB1 alleles and anti neutrophil cytoplasmatic antibodies (ANCA) in Han and Uygur ulcerative colitis (UC)patients in Xinjiang region.Methods The serum ANCA was determined by indirect immunofluorescence assay in 62 Uygur UC patients,58 Han UC patients,188 Uygur and 184 Han healthy control individuals.HLA-DRB1 typing was performed by polymerase chain reaction-sequence based typing (PCR-SBT).The allele frequency of HLA-DRB1 was compared in ANCA positive and negative Han and Uygur patients as well as healthy controls.Stratified analysis was performed according to UC clinical type,severity and involvement.SPSS 17.0 software was applied for x2 test.Once P<0.05,the odds ratio (OR) and 95% confidence intervals (95%CI) was calculated.Results The positive rate of ANCA in Uygur UC patients (53.2%,33/62) was significantly higher than that of Han patients (34.5%,20/58) and the difference was statistically significant (x2=4.269,P =0.045).In Uygur,the gene frequency of HLA-DRB1 * 13 in ANCA positive UC patients (0.202)was significantly higher than that of ANCA negative patients (0.017) (x2 =10.092,P=0.016,OR=16.000,95%CI:2.892 to 88.524) and healthy controls (0.075) (x2=9.351,P=0.040,OR=3.407,95%CI:1.666 to 6.971).The gene frequency of HLA-DRB1 * 13 in ANCA positive pancolitis type UC patients (9/15) was significantly higher than that of ANCA negative pancolitis type UC patients (1/14) and the difference was statistically significant (x2=8.955,P =0.040,OR =19.500,95%CI:2.787 to 136.461).However,in Han patients,there were no significant differences of HLA-DRB1 alleles frequencies among ANCA positive patients,ANCA negative patients and healthy controls (all P>0.05),and the results of stratified analysis were same.Conclusions In Uygur UC patients of Xinjiang region,HLA-DRB1 * 13 may correlated with ANCA and with ANCA of pancolitis type UC patients.There is no such correlation in Han patients of Xinjiang region.
6.A correlation between benign prostate hyperplasia and atherosclerosis
Chinese Journal of Geriatrics 2011;30(11):919-920
ObjectiveTo investigate the correlation between benign prostate hyperplasia (BPH) and atherosclerosis (AS).Methods 95 cases were divided into two groups based on prostate volume (PV):24 cases with non-BPH (PV≤20 ml) and 71 cases with BPH (PV>20 ml).Carotid intinal medial thickness (IMT) was determined by high resolution color Doppler sonography.ResultsLevels of triglyeeride (TG),hypersensitive C reactive protein (hs-CRP),ln fasting insulin [ln (FINS)],ln insulin resistance index [ln (HO)MA-IR)] and IMT in BPH group were significantly higher than in non-BPHgroup.The morbidity rate of coronary heart disease and cerebral arteriosclerosis in the BPH group enhanced as compared with non-BPH group.PV were positively correlated with ln(FINS),ln(HOMA-IR),TG and high density lipoprotein (HDL-C).Conclusions BPH is closely correlated with AS and their co-pathogenesis might be insulin resistance,inflammatory reaction and endothelial dysfunction.

Chinese Journal of Diabetes 2008;16(1):12-14
Objective To investigate the relation of peripheral leukocyte total and its differential counts with urinary albumin(UAlb)in patients with type 2 diabetes.Methods The 564 subjects with type 2 diabetes were stratified according to UAER levels.The total and differential leukocyte counts of peripheral blood were measured.Demographic and potential metabolic confounding factors were analyzed with multiple correlation and logistic regressions to evaluate the effects of leukocyte counts on UAER.Results With the increase of UAER,the peripheral total leukocyte,neutrophil,monocyte,eosinophil and basophil counts increased.In contrast,the lymphocyte count decreased.The differences persisted even after adjusting the influence of age,sex,duration of diabetes and other known risk factors.Conclusions Our study shows that peripheral leukocyte counts,even within the normal range,are related with UAlb in subjects with type 2 diabetes in a dose-dependent manner.
8.Analysis of the different levels of serum high sensitivity C-reactive protein and its related factors in subjects with isolated IGT or IFG
Chinese Journal of Diabetes 2008;16(2):76-78
Objective To compare the levels of serum high sensitivity C-reactive protein(hsC-RP) among subjects with normal fasting glucose plus normal glucose tolerance(NFG/NGT),IFG,IGT and IFG plus IGT,and to analyze the related risk factors. Methods 443 nondiabetic subjects aged 39-65 years were seperated into four groups:NFG plus NGT,IFG,IGT and IFG plus IGT.The serum hsC-RP levels and related factors were analyzed. Results Compared with IFG subjects,IGT subjects had higher hsC-RP levels.No differences in hsC-RP levels were found between NFG plus NGT group and IFG group, as well as between IGT group and IFG plus IGT group.Stepwise multiple regression showed that BMI and HOMA-IR were independent predictors of hsC-RP. Conclusions IGT subjects have significantly higher serum hsC-RP level than IFG subjetcts. The serum level of hsC-RP is associated with insulin resistance and the components numbers of metabolic syndrome.
