Objective To investigate the correlation between vitamin D receptor gene and bone mass and obesity phenotypes in patients with type 2 diabetes mellitus.Methods 318 patients with type 2 diabetes were chosen as diabetes group,and 50 healthy people were selected as healthy control group.Vitamin D receptor gene Apa Ⅰ type was detected in the two groups.Height,weight and body mass index(BMI)biochemical index,fat content(FM),lean tissue content(LM)and bone mineral density were detected in patients with type 2 diabetes mellitus.The relationship between vitamin D receptor gene(Apa Ⅰ)polymorphism and BMD and obesity phenotypes in type 2 diabetes was analyzed.Results The VDR gene distribution between the diabetes group and healthy control group showed no signif-icant difference(Z =0.561,P >0.05).The vitamin D receptor genotype in the diabetes group included AA 31 cases (9.7%),Aa type 108 cases(34.0%),aa type 179 cases(56.3%),while the vitamin D receptor genotype in the healthy control group comprised AA 7 cases(9.3%),Aa type 29 cases(38.7%),aa type 39 cases(52.0%).The percentage of AA in both groups was significantly less than that of Aa and aa(χ2 diabetic group =4.127,3.976,all P <0.05;χ2 healthy control group =5.129,4.213,all P <0.05).Proportion of normal bone mass and average bone density in AA,Aa,aa type decreased(χ2 =15.552,P <0.05;F =5.127,P <0.05),the genotype AA was not detec-ted in osteoporosis group.BMI and FM were the highest in AA,which were significantly higher than those of Aa,aa (F =4.319,4.263,all P <0.05).Conclusion Vitamin D receptor gene Apa Ⅰ type polymorphism is related with BMD and obesity in type 2 diabetes mellitus,and it has predictive value on bone mass changes.The increase of BMI and FMmay be beneficial to bone mineral density.

Objective To investigate the changes of monocyte chemoattractant protein-1(MCP-1)in serum and urine of lupus nephritis(LN)patients in active phase and remission phase.Methods The levels of MCP-1 in serum and urine of 58 LN patients(27 of active phase and 31 of remission phase)were measured by ELISA.The correlation between the levels of MCP-1 in variant phase of LN and other relevant factors were analyzed.Results The MCP-1 levels in sera of both active phase and remission phase of LN patients were markedly higher than those in controls(548.5?347.2 ng/L and 469.1?298.4 ng/L vs 273.3?146.7 ng/L,P0.05).Conclusion The MCP-1 levels in urine of LN patients is more suitable to evaluate the activity of disease as a sensitive marker.

Objective To investigate the protective effect and it's possible mechanism of Tanshinone ⅡA in radiation-induced pulmonary fibrosis.Methods Having the right hemithorax of female Wistar rats irradiated(30?Gy) in 10 fractions within 14 days by 6 ?MV photons,the radiation-induced pulmonary fibrosis animal model was established.In the treatment group,sodium Tanshinone ⅡA sulfonate(15?mg/kg) was given by intraperitoneal injection 1 hour before each fraction of irradiation.Five months after irradiation,the difference of the histopathological changes,the hydroxyproline content and expression of TGF-?1 between the radiation alone group,tanshinone plus radiation and control group were analyzed by HE stain,Massion stain,immunohistochemical methor and reverse transcriptase polymerase chain reaction(RT-PCR) method.Results The histopathological comparison revealed the protective effect of Tanshinone ⅡA.The content of hydroxyproline was(21.99?3.96),((38.25?)(7.18)),(28.94?4.29)??g/g in the control group,radiation alone group and radiation plus Tanshinone ⅡA.The expression of TGF-?1(mRNA and protein) was reduced by Tanshinone ⅡA.Pathological changes of the pulmonary fibrosis was reduced by Tanshinone ⅡA yet.Conclusions Our study shows that Tanshinone ⅡA can inhibit radiation-induced pulmonary fibrosis,and the possible mechanism of its may be made possible through down-regulating the expression of TGF-?1 in the irritated lung tissue.

Objective To study the cell metabolism changes of hippocampal region in patients with vascular dementia (VD) after stroke by 1 H-magnetic resonance spectroscopy (1 H-MRS),and to observe the relationship between cell metabolism changes and clinical symptoms after donepezil hydrochloride treatment.Methods Enrolled 18 patients with VD after stroke,16 males and 2 females,with a mean age of (76.9±2.7) years,13 patients without VD after stroke,11 males and 2 females,with a mean age of (76.2±3.6) years and 14 health volunteers as control group,12 males and 2 females,with a mean age of (75.1+2.4) years.The mini-mental state examination (MMSE),activities of daily living (ADL) and Hamilton depression scale (HAMD) were used to assess the effects on cognitive function,ability of daily living and behavior symptoms.1 H-MRS examination of bilateral hippocampus was conducted in all subjects.Metabolisms of N-acetylaspartate (NAA),choline (Cho) and creatine (Cr) were examined and the ratios of NAA/Cr and Cho/Cr were calculated.The patients with VD were prescribed donepezil and given 1 H-MRS assessment half a year later.Results The patients with VD had a significantly lower NAA/Cr ratio in bilateral temporal hippocampus area than did health controls and the patients without VD (F=4.23,4.98,both P＜0.05),and a higher Cho/Cr ratio than did health controls and the patients without VD in left hippocampus (P＜0.05).The NAA/Cr and Cho/Cr ratios in patients without VD had no significant changes compared to health controls.There was a positive relationship between MMSE score and NAA/Cr ratio,and negative relationship between MMSE score and Cho/Cr ratio in the bilateral hippocampus area in patients with VD.After 6 months of treatment of donepezil hydrochloride,the MMSE and ADL scales significantly increased (both P＜0.05),and NAA/Cr ratio had no significant change in hippocampal region (t=-2.02,-2.04,both P＞0.05),whereas Cho/Cr had significant decrease (t=2.86,2.23,both P＜0.05).Conclusions The data suggest that the lower NAA/Cr ratio and higher Cho/Cr ratio in hippocampus area might be helpful in distinguishing VD and no-VD in patients with stroke.Donepezil improves general cognition function in patients with VD,which may be associated with regulating the cholinergic pathogenesis of VD in vivo and in vitro.

Objective To observe the levels of matrix metalloproteinases-9 (MMP-9) and tissue factor (TF) as well as blood lipid in patients with acute coronary syndrome (ACS) ,and to study the effect of Fluvastatin on levels of serum MMP- 9 and plasma TF. Methods 40 patients with ACS were selected (including 20 patients with AMI and 20 patients with UAP) ,20 stable angina patients (SAP) and 13 patients without coronary heart dis-ease as control group. 40 patients with ACS were randomly assigned to the Fluvastatin group (n = 20) and the rou-tine group (n = 20) in this study. The MMP - 9 and TF were detected on admission and after 2 weeks treatment. Re-suits The levels of MMP-9 and TF were significantly higher in ACS group than that of SAP and control group (P < 0.001 ,P < 0.05) ,which were elevated in AMI group compared with that of UAP group (P < 0.05). The levels of cholesterol (TC) ,low density Lipoprotein (LDL - C) ,MMP- 9,TF decreased significantly at two weeks after treat-ment in fluvastatin group (P < 0.05), but no significant changes were observed in the routine group (P > 0.05). The change of MMP 9, TF and blood lipid was not related in fluvastatin group (P > 0.05). Conclusion Serum MMP-9 and plasma TF in ACS patients are significantly elevated and fluvastatin decreases the levels of MMP-9 and TF after two weeks treatment,so it may be benefit to atheroaclerotic plaque stabilization and prohihit thrombosis for-marion, and this is not related to regulation of blood lipid.

Objective To observe the curative effect about heavy abdomen type of anaphylactoid pur-pura treated by Methylprednisolone associate with Heparin. Methods Randomly divided eighty three children with heavy abdomen type of anaphylactoid purpura who treated in department of pediatrics of the first hospital affiliated to Kunming medical college from January, 2006 to december, 2007 into group A (treated by Hydro-cortisone) and group B (treated by Methylprednisolone) and group C(treated by Methylprednisolone associate with Heparin). Group A treated by mainline Hydrocortisone dose of 5～8 mg/kg body weight once a day,mixed into 100ml 5% glucose injection, after 7～14 days later, instead of take orally Predisone tablet and de-grees dose by gradually. Group B treated by mainline Methylprednisolone dose of 2～4 mg/kg body weight once a day, mixed into 100ml 5% glucose injection, after 7～14 days later, instead of take orally Predisone tablet, and group C treated by Methylprednisolone by oneself (dose like group B) associate with mainline Hep-arin (dose of 0.25～0.75 mg/kg body weight once a day, mixed into 100ml 5% glucose injection) 7～10 days. Observe clinic symptomatic like as tetter, bellyache, entron hemorrhage when treatment of every group. Contrast reiteration rate of anaphylaetoid purpura, and the period of urine test get hack normal which cases with kidney tamper. Contrast these medication' s side effect such as resort of natrium and water, elec-trolyte turbulence, hemorrhage and so on. Results Group C (treated by Methylprednisolone associate with Heparin) is better then group A (treated by Hydrocortisone) and group B (treated by Methylprednisolone by oneself) in eliminate tetrer and release bellyache. The less period of group C need to treatment entron hemor-rhage and urine test get hack normal. And thereiteration rate is less of group C than group A and group B.Conclusion Methylprednisolone in association with Heparin to treat heavy abdomen type of anaphylactoid purpura is better than hydrocortisone and Methylprednisolone by oneself in controling symptom, reduing reiter-ation rate and more less side effect. So methylprednisolone in association with Heparin to treat of heavy ab-domen type of anaphylactoid purpura is a ideal project.
