Objective To evaluate the usefulness of MRI in the diagnosis of adenomyosis. Methods Sagittal Turbo SE T 1WI, T 2WI, T 1SPIR and T 2SPIR MRI examination were performed on 30 cases with adenomyosis. Results The lesions in 12 cases with diffuse adenomyosis were demonstrated as diffusely thickened junctional zone (JZ) measured 10～35 mm (mean 18 mm) On T 2WI. 6 of them were of homogenous hypointensity. Another six had hyperintensive foci within the hypointensive lesions on T 2WI, and these hyperintensive foci could also be found on T 1WI in 5 lesions. 23 focal lesions (adenomyomas) in 18 cases were oval, irregular or round masses with hypointensity that were the same as the intensity of JZ on T 2WI. They were from 2.0-7.5 cm in diameter (mean 3.9 cm), and all but one showed ill-defined margins. 15 masses hadhyperintensive foci within the hypointensive lesions on T 2WI and 12 of 15 presented hyperintensity on T 1WI. The diffusely thickened JZ and focal masses correspond to the hyperplastic and hypertrophic musculature around the heterotopic endometrial islands. The hyperintensive foci were correlated with the heterotopic endometrial islands. The hyperintensive foci showed only on T 2WI corresponded to the heterotopic endometrial islands without hemorrhage. The hyperintensive foci shown on both T 2WI and T 1WI were the heterotopic endometrial islands with hemorrhage. Conclusion MRI is the modality of choice for the diagnosis of adenomyosis. T 2WI is the most useful sequence. T 2WI combining with T 1WI, T 1SPIR, and T 2SPIR can improve the accuracy in the diagnosis of adenomyosis.

Diabetic nephropathy presents an increasing trend worldwide. It has been an attractive area to find novel targets for the treatment of diabetic nephropathy. SIRT1 (Sirtuin 1), a member of deacetylation enzymes, regulates cell senescence, metabolism, and apoptosis. In last ten years, lots of studies showed that SIRT1 exerts a protective effect in the progression of the diabetic nephropathy by promoting reconstruction of energy homeostasis, modulating cell redox state, resisting cell apoptosis, inhibiting inflammation and ameliorating renal fibrosis. SIRT1 has become a potential new target for the treatment of diabetic nephropathy.

Objective To investigate the risk factors,clinical characteristics and outcomes in patients with acute myocardial infarction and history of stroke. Methods A total of 771 patients with acute myocardial infarction diagnosed and admitted to Xuanwu Hospital,Capital Medical University from January 2005 to March 2012 were analyzed retrospectively. They were divided into either a stroke group (n=387)or a control group (n=384)according to whether they had previous ischemic stroke or not. The risk factors for cardiovascular disease,clinical characteristics of the disease,and clinical outcomes of the patients in both groups were compared through the case control analysis. The endpoint events observed were acute ischemic stroke,cerebral hemorrhage,and cause of death during hospitalization. Results (1)The median age of the patients in both stroke and control groups was 71 (37-91 )and 62 (29-90 )years respectively. The female patients in the stroke group were more than those in the control group (n=125 vs. n=91). The incidence of complicated with hypertension (72. 9%[n=282]and 47. 6%[n=183]) and type 2 diabetes mellitus (39. 0%[n=151]and 20. 8%[n=80]respectively)were high. There was significant difference between the two groups (P<0. 01). (2)The time from the onset to admission in patients of the stroke group was longer than that in patients of the control group (median 11 h vs. 4 h). The incidence of non-ST segment elevation myocardial infarction (16. 0%[n = 62 ]and 1. 8%[n = 7 ] respectively)was higher. The incidences of complicated with gastric stress ulcer (7. 0%[n =27 ]and 2. 1%[n=8]respectively),atrial fibrillation (10. 6%[n=41]and 3. 9%[n=15]respectively),and acute pulmonary edema-cardiac function Killip class≥Ⅱ(51. 9%[n =201 ]and 37. 8%[n =145 ] respectively)were more higher. The findings of coronary angiography in patients of the stroke group were that the incidence of left main coronary artery or 3 -branch lesion higher than that of the control group (52. 9%[126/238]and 32. 4%[97/299]respectively). There was significant difference (P <0. 05). (3)The incidence of new stroke in patients of the stroke group (5. 7%[n =22 ]and 1. 8%[n =7 ] respectively)and in hospital mortality (13. 7%[n=53]and 7. 6%[n=29]respectively)were higher than those of the control group. There were significant differences (P<0. 01). Conclusion The age of the patients with acute myocardial infarction with previous identified history of stroke is older. The incidence of female patients is higher than that of the non-stroke patients,and most of them have risk factors that complicated with hypertension and diabetes mellitus. These patients often have the complications with peptic ulcer disease and heart failure,and their coronary angiography often show multi-branch lesions,and they are more prone to ischemic cardio-cerebrovascular events during the hospitalization.

ObjectiveTo explore the effects and possible mechanisms of VCR combined with low dose cyclophosphamide(CTX) intermittently to treat severe systemic lupus erythematosus(SLE).It is assumed that this might be a new combination therapy for SLE and expected to improve the overall prognosis and outcome of SLE.MethodsMurine chronic graft-versus-host disease(cGVHD) model were developed for study.They were randomly divided into the control group,vincristine (VCR) pulse therapy group,CTX pulse therapy group,CTX every other day(EOD) group,VCR+CTX combination group.One way ANOVA and repeated measure variance analysis were used for statistical analysis.Results① Six weeks after cGVHD models were set up,the average 24-hour urine protein quantification was(5.02±0.88) mg,anti-dsDNA antibody was positive,and Ⅳ LN pathology could be observed histologically in the model murine.So cGVHD models were successfully developed.② Significantly difference in decreasing of 24-hour urine protein quantification was found in the CTX EOD group,VCR+CTX combination group and other groups (P＜0.01).Significant decrease in Cr,ALT,anti-dsDNA,was found in the CTX EOD group,VCR+CTX combination group,CTX pulse therapy group and other groups(P＜0.05).Decrease in urine MCP-1 and TGF-β1 could be detected,and statistical significant difference in these parameters could be found in the CTX EOD group,CTX pulse therapy group,VCR+CTX combination group and other groups (P＜0.01).MCP-1 and TGF-β1'expression in model kidney were reduced in the CTX EOD group,VCR+CTX combination group and had statistical significant difference in the CTX EOD group,VCR+CTX combination group,VCR pulse therapy group,and CTX pulse therapy group.③ VCRand CTX combination treatment was effectivein 24-hour urine protein quantification,blood Cr,ALT,anti-dsDNA and urine MCP-1,as well as urine TGF-β1 (P＜0.05).Conclusion ① The combination of VCR and CTX is synergistic in decreasing 24-hour urine protein quantification,Cr,and the expression of MCP-1,TGF-β1.② The adverse effect of VCR+CTX combination group is similar to VCR pulse therapy group and CTX pulse therapy group.

Objective To examine the impact of C-reactive protein (CRP) on the expression of interleukin-6 (IL-6), inflammatory cytokine, in cultured human pulmonary artery smooth muscle cells (hPASMCs) in order to find out the cause of pulmonary artery hypertension (PAH). Method The hPASMCs were cultured and stimulated by different concerntrations of CRP (5 - 200 μg/ml) for different lengths of time. The activity of nuclear factor-κB (NF-κB) was evaluated by electrophoretic gel mobility shift assay (EMSA). The expression of IL-6 mRNA and the level of IL-6 protein were measured by using real-time PCR and ELISA, respectively. Results CRP increased IL-6 production in hPASMCs in a dose-dependent manner. The increase in IL-6 at concerntration of 200 μg/mL in the CRP group was as high as 2.8times that in the control group. CRP also significantly induced the activation of NF-κB in hPASMCs. The effect of CRP on the inflammatory cytokine, IL-6, was inhibited by the specific FcγⅡa receptor antibody.Conclusions In vitro, CRP increases the production of IL-6 in hPASMCs mediated by FcγⅡa receptor and NF-κB translocation. These data offer important insights into the role of CRP in the pathogenesis of PAH.
