Objective To investigate the correlation between uric acid level and macrovascular disease in type 2 diabetic patients.Methods Sixty type 2 diabetic patients with lower limb atherosclerosis of carotid artery were randomly selected in study group who hospitalized in the First Hospital of Zibo from Mar.to Feb.2012.Sixty type 2 diabetes mellitus(T2DM) without carotid and lower limb athemsclerosis were served as control group.The blood pressure,blood lipid,blood glucose and other biochemical indexes,including blood uric acid,serum insulin (FNS),fasting blood glucose (FPG),apolipoprotein a (LP (a)),apolipoprotein A1,B (APO-A1,APO-B),glycosylated hemoglobin (HbA1c),high density lipoprotein cholesterol (HDL-C),low density lipopmtein cholesterol (LDL-C),triacylglycerol (TG) and total cholesterol (TC) were measured and determined.Results There was no significant difference in terms of blood pressure,blood lipid levels,APO-A1,APO-B,HbA1C,FNS and FPG in study group patiems (P ＞ 0.05).The level LP(a) in study group was (0.4 ± 0.2) g/L,significantly higher than that in control group ((0.2 ± 0.2) g/L; t =3.842,P ＜ 0.01).The blood uric acid level in study group was (362.3 ± 112.8)mmol/L,significantly higher than that of the control group((284.8 ±68.6)mmol/L;t =3.188,P＜0.01).Conclusion Uric acid and LP(a) are involved in the oocurrence and development of athemsclemsis,which is close related to the development of type 2 diabetic macmangiopathy.Therefore,in the process of preventing type 2 diabetes with macroangiopathy,we should pay attention to uric acid and LP (a) of the patient beside effective control of blood glucose,blood pressure,blood lipid level.

Objective To observe the clinical efficacy of hydro-medicinal cupping using Chinese medicinal granules in treating discogenic low back pain. Methods Sixty patients with discogenic low back pain were randomized into a treatment group and a control group, 30 in each group. The two groups were both intervened by hydro-medicinal cupping at Yaoyangguan (GV 3) and two sides of the point, while the Chinese medicinal granules were used in the treatment group and the conventional form of medicine was used in the control group. The pain score was observed before treatment and after 4 treatment courses, and the clinical efficacies were also compared. Results The pain scores were significantly changed after intervention in both groups (P<0.01). After intervention, there was no significant difference in comparing pain score between the two groups (P>0.05). The total effective rate was 93.3%in the treatment group versus 96.7% in the control group, and the difference was statistically insignificant (P>0.05). Conclusions Hydro-medicinal cupping is an effective approach in treating discogenic low back pain, and there is no marked difference in efficacy between the Chinese medicinal granules and conventional form of medicine.

Compared with the model group, the levels of FBG, froctosamine content in Chinese herbal compounds high and medium dose groups and metformin group were lower, while fasting insulin level increased after 4 weeks'medication (P<0.05).Conclusion TCM herbal compounds can increased the basic insulin level by decreasing the contents of FBG and fructosamine.

BACKGROUND: The oriented migration of bone marrow mesenchymal stem cells may depend on the interaction between local chemotactic factors and cellsurface receptors. However, which chemotactic factors may mediate the oriented migration of bone marrow mesenchymal stem cells towards the fracture site remains unclear. OBJECTIVE: To tag autologous bone marrow mesenchymal stem cells, evaluate its role in bone healing, and detect the highly expressed factors associated with migration of bone marrow mesenchymal stem cells in the microenvironment. METHODS: The fluorescence/chimeric C57BL/6 mouse models were established, then left shankbone fracture models were also produced. The percentages of green fluorescent protein positive cells to al cells at the fracture site and the percentage of osteoblasts differentiated from bone marrow mesenchymal stem cells to al the osteoblasts were detected at different time points. The role of bone marrow mesenchymal stem cells in the fracture repairing was evaluated. The levels of chemotactic factors protein expression at the fracture site in different time points were detected with immunohistochemistry technology. RESULTS AND CONCLUSION: The percentage of green fluorescent protein positive cells to al cells at the fracture site was (3.011±0.911)%, (9.031±0.145)%, (12.064±0.145)% at 1, 5, 14 days postoperatively; and osteoblasts differentiated from bone marrow mesenchymal stem cells accounted for 50% of al the osteoblasts. After fracture, the stromal cel derived factor-1, colony stimulating factor, hepatocyte growth factor, monocyte chemoattractant protein-1, and matrix metal oproteinases-9 were expressed to varying degrees in the microenvironment, while the expression of granulocyte colony-stimulating factor was negative. The expression of stromal cel derived factor-1 in the fracture microenvironment was the highest, mainly due to the migration of bone marrow mesenchymal stem cells. Experimental findings indicate that, autologous bone marrow mesenchymal stem cells participate in and play an important role in bone healing. The stromal cel derived factor-1 plays an important role in promoting bone marrow mesenchymal stem cells migration and promoting bone healing.

BACKGROUND:The glial scar is a major obstacle to the regeneration of the central nervous system, which plays a physical and chemical barrier role to central nervous system regeneration. How to effectively inhibit glial scar formation and promote axonal regeneration has great significance.
OBJECTIVE:To explore the effect of the immune response in the formation of the glial scar after spinal cord injury.
METHODS:A computer-based online search was performed in the PubMed database and the CNKI database for the articles on the mechanisms of spinal cord injury, immune cel s and spinal cord injury as wel as the glial scar formation after spinal cord injury from January 1990 to January 2013. The key words were “spinal cord injury, immunity, glia scar”in Chinese and English. The languages of the articles were limited in Chinese and English. Final y, 72 articles were included for the further analysis according the inclusion criteria.
RESULTS AND CONCLUSION: After spinal cord injury, the effect of autoimmune response in which stil been much debated. Studies showed that spinal cord injury can cause suppression of cel ular immunity and non-specific immune function, causing immune function decreasing. Monitoring immune indicators and improving immune function have great significance in promoting the ful rehabilitation of patients with spinal cord injury. Glial scar is the most important factor to prevent the repairing after spinal cord injury. Immune and inflammatory response is the main reason to secondary spinal cord injury. Degree of repair after spinal cord injury mainly depends on the protection of the residual neurons in order to keep them off secondary damage. However, autoimmune T cel s can protect the residual neurons, the specific effect of T lymphocytes in glial scar formation after spinal cord injury is stil unclear, and further exploration is needed.
