Lifestyle intervention is basic and background treatment for people with type 2 diabetes.Effective lifestyle intervention contributes to better glucose control and delay of diabetic complications.Dietary and exercise interventions as well as lifestyle advice are major components of lifestyle intervention.Dietary intervention focuses on restriction of total caloric intake and balanced nutritional composition,while exercise intervention focuses on exercise mode,frequency,intensity,timing,and duration.This review introduced several lifestyle intervention measures including exercise and dietary interventions as well as lifestyle advice,and discussed their effects on glucose control in people with type 2 diabetes.

ObjectiveTo determine the effect of acute and chronic spinal cord injury (SCI) resulted from thoracic cord transection on the urinary bladder spinal neural pathway.Methods76 adult Sprague-Dawley rats were randomly divided into 4 groups, non-SCI, SCIa, SCIb and SCIc respectively. The non-SCI rats underwent no surgical procedure except Pseudorabies virus (PRV) tracer injection into the bladder tissue, while the rats of other groups were spinalized and given PRV injection at different time after SCI. Transcardiac perfusion fixation was done in appropriate survival periods after PRV injection. Then sections of dorsal root ganglion (DRG) and spinal cord were processed for visualization of virus by the Streptavidin-Peroxidase (SP) immunohistochemical procedure. All sections were measured with the Olympus Cue-2 image analysis system.ResultsThe bladder weights in SCIb and SCIc groups markedly increased (P<0.001). The time-ordered flow charts of PRV tracing were similar in the non-SCI rats and in the SCI rats. The cross-sectional area of the labeled DRG cell profiles increased significantly after SCI (P<0.001). The number of labeled cells in dorsal horn in L6 and S1 segments 3 days after PRV injection markedly increased in chronic SCI rats, and so did the number of labeled motor neurons 4 days post-injection. ConclusionThe acute and chronic SCI have little effect on the process of virus transneuronal transport below the level of lesion. Subsequent to chronic SCI, marked reorganization of the micturition reflex pathways occurs.

Objective To determine the protein and mRNA levels ofinterleukin-17 (IL-17) and the proportion of Th17 cells in the peripheral blood of patients with systemic lupus erythematosus (SLE) and their clinical significance is analyzed. Methods Twenty-five hospitalized SLE patients were recruited and twentytwo healthy volunteers were enrolled as normal controls. Plasma protein and mRNA of IL-17 in the peripheral blood were measured by enzyme-linked immunosorbent assay and real time-PCR respectively. Flow cytometric assay was used to analyze the percentage of Th17 cells in SLE patients. The relationship between IL-17/Th17 cells and clinical or laboratory parameters of SLE patients was explored. Students' t-test and Spearman's correlation was used to evaluate the relationship between mRNA level and inflammatory parameters. Results The plasma concentration and mRNA level of IL-17 was significantly elevated in SLE patients as compared to the normal controls (P＜0.05). The percentage of Th17 cells in patients with SLE was higher than that of normal controls and was significantly increased in more active SLE patients and SLE with nephritis than less active SLE and SLE without nephritis (P＜0.05). Both plasma levels of IL-17 and the proportion of Th17 cells were positively correlated with SLEDAI (r=0.681, P＜0.01; r=0.426, P=0.034). Conclusion Plasma IL-17 protein and mRNA expression level and the percentage of Th17 cells in SLE patients are all significantly elevated and the close relationship between IL-17/Th17 cells and disease activity suggests that IL-17/Th17 may play an important role in the pathogenesis of SLE.

Objective To report the results of the surgical treatment of cervical spondylotic myelopathy(CSM) secondary to athetoid cerebral palsy and clarify the characteristics and the principle of treatment of the disease. Methods The age of the patient, segments of vertabrae involved and operated upon, results and complications of 32 cases with CSM secondary to athetoid cerebral palsy were statistically analyzed and compared with 93 patients who had isolate CSM operatively treated at the same time. Results 1)The average age of the patients in the group of CSM secondary to athetoid cerebral palsy was 37.94 years,and in the group of isolate CSM was 52.48 years, with significant statistic difference(P

Purpose To detect whether a 3243 point mutation existed in age related macular degeneration (AMD). Methods Twenty six cases of wet form AMD patients, ten cases of dry form AMD patients were selected,and compared with twenty nomal controls. After collecting anti coagulated blood samples, total cellular DNA were extracted and purified. Using polymerase chain reaction and restriction fragment long polymorphism techniques, the mtDNA A→G point mutation at position 3243 were detected. Results After cleaveded by restriction endonuclease Apa I, a 294 bp fragment remained only in all detected DNA samples including twenty six wet form AMD, and ten dry form AMD. No any other fragment appeared. The result showed that there was no A→G mutation at position 3243 found in AMD. Conclusion It is suggested that mtDNA 3243 point mutation due to maternal inheritance might be not concerned with both wet form AMD and dry form AMD.

Objective To investigate the characteristic of type 2 diabetes (T2DM) patients with coronary heart disease (CHD),and provide methods for prevention and treatment for patients who suffered from CHD.Methods The hospitalized patients were divided into three groups.The treatment group contains 46 cases who were T2D with CHD;The control group Ⅰ contains 30 cases who were T2DM without CHD;The control group Ⅱ contains 50 cases who were CHD without T2DM.Their ordinary circumstances were compared;the blood sugar,BP,TC,TG,HDL,LDL,HbA1c,C-P,Ins were measured.Insulin sensitive index(ISI) was calculated.Results Three groups had obvious statistical differences in BP,TC,LDL-C,ISI,HbA1 c.Diabetic patients with CHD have more common with three lesions.Conclusion In the clinical job,the composite observation should be strengthened and treatment because the factors of atherosclerosis in T2DM patients were numerous and complex.

[Objective]To study the effect of intra-operative three-dimensional fluoroscopy-based spinal navigation guidance for vertebroplasty to treat osteoporotic vertebral compression fracture(OVCF).[Method]A clinical study was performed in which 41 patients suffering painful osteoporotic vertebral compression fractures underwent vertebroplasty procedure.During this procedure,cannulation of the pedicle and vertebral body was performed with the aid of isocentric 3D fluoroscopy-based spinal navigation(group A) and biplanar fluoroscopy(group B).RDQ and VAS of each group was compared between preoperation and postoperation.Total operating time,intra-operative fluoroscopy time and pedicle puncturation accuracy were compared between group A and group B.Possible complications such as cement extravasations were evaluated with X-ray fluoroscopy.[Result]Forty-six vertebrae were successfully injected with polymethyl methacrylate.The two groups had statistically significant difference in RDQ and VAS between preoperation and postoperation,but no statistically significant difference between the two groups.Mean operating time and intra-operative fluoroscopy times of group A were shorter than those in group B.There was no case of broken pedicle in group A.One vertebra was found to have bone cement leakage to soft tissue in group B,but the vertebral canal and pedicle intact.The author followed up for an average of 21 months(range 8～38 months) and found no severe complication or collapse of vertebra.[Conclusion]With the aid of intra-operative three-dimensional fluoroscopy-based spinal navigation,vertebroplasty can be performed more accuractly and securely.The shorter total operating time,intra-operative fluoroscopy times are convincing and less possible complication can be expected.

AIM:To investigate the influential factors of the blood-brain barrier (BBB) permeability and to observe the effects of zileuton,a selective 5-lipoxygenase inhibitor (5-LO),on focal cerebral ischemia-reperfusion injury (CIRI).METHODS:The right middle cerebral artery of the rat was occluded by inserting a thread through internal carotid artery for 2 h,and then reperfused for 24 h. Zileuton (10,50 mg?kg-1,po) was orally administered 2 h before ischemia and at 0,5,10 h after reperfusion. The permeability of blood brain barrier (BBB) was detected by using Evans blue (EB) as a labelling compound. The degree of cerebral edema was estimated by AutoCAD image analysis software. The mRNA of cysteiny leukotrienes receptor1 (CysLTR1) was detected by RT-PCR. The content of LTB4 in serum was measured by enzyme linked immunosorbent assay (ELISA). The expressions of AQP4 and MMP-9 proteins were measured by immunohistochemical staining method. RESULTS:After middle cerebral artery occlussion 2 h/reperfusion 24 h,the permeability of BBB in the brain tissue of injured side and the brain edema degree were increased. The content of LTB4 in serum was elevated. The expression of CysLTR1 mRNA from the brain tissue of occluded side was enhanced. The expressions of MMP-9 and AQP4 proteins of the ischemia realm and ischemia penumbra (IP) of the infarct focus perimeter were increased. Both 10 and 50 mg?kg-1 doses of zileuton dramatically relieved the BBB permeability destruction and the degree of the brain edema,inhibited the expression of CysLTR1 mRNA in the brain tissue and also reduced the content of LTB4 in serum. The expressions of AQP4 and MMP-9 proteins in the brain tissue were also decreased.CONCLUSION:The permeability of BBB is destroyed after the focal CIRI. The mechanisms of protective effect of zileuton might be attributed to its effects by inhibiting the activation of 5-LO pathways on the brain tissue and circulatory blood,reducing the expressions of AQP4 and MMP-9 proteins of the ischemia and IP realm in the brain tissue.
