Objective To study the clinical characteristics and imaging features of alien hand syndrome (AHS). Methods We retrospectively analyzed the clinical data of 3 typical cases in our hospital,in comparison with case reports and reviews of domestic and foreign during the past decade. Result All 3 patients showed corpus callosum lesions from CT or MRI detections. The symptoms of the patients included alien hand sign , abnormal involuntary movements, intermanual conflict of upper limbs, and so on. And the patients accompanied with emotional and cognitive changes. Two of them were improved in different degrees after treatment. Conclusion AHS was a complex disease. The diagnosis of this syndrome was based on the advanced neuroimaging. There was still no well established treatment for AHS.

AIM: To establish the quality standard for Compound Songluo Granule (Rhizoma Corydalis, Radix Angelicae Sinensis, Lichen Usneae). METHODS:Rhizoma Corydalis, Radix Angelicae Sinensis were identified by TLC. Usnic acid in Lichen Usneae was determined by TLCS. RESULTS: Rhizoma Corydalis, Radix Angelicae Sinensis could be detected by TLC. Usnic acid showed a good linear relationship at the range of 0. 50～2.50 ?g, r=~0.999 9. The average recovery was 97.5% and RSD was 2.61%, respectively. CONCLUSION:The method is available with a good reproducibility and can be used for the quality control of Compound Songluo Granule.

Thyroid-stimulating hormone receptor(TSHR)is an important autoantigen whose cleavage and shedding can induce autoimmunity.The TSHR is the main functional receptor of the thyroid.The shedding of the ? subunit plays an important role in the forming of TSAb and balancing between TSAb and TBAb.Research on the cleavage and shedding of the TSHR extracellualar domain helps to gain a deep insight into the structure and function of TSHR,illuminate the pathogenesis of autoimmune thyroid disease and find out a new therapy.The structure of TSHR,the mechanism and the significance of its cleavage and shedding are reviewed in this article.

Objective To investigate alterations in epigenetic regulation in B cells in subacute cutaneous lupus erythematosus (SCLE).Methods Peripheral blood mononuclear cells (PBMC) were isolated from the peripheral venous blood of SCLE patients and healthy donors with density gradient centrifugation.B cells were isolated with CD19 micro beads and protocols provided by the manufacturer.Total RNAs were isolated with RNA kits.The expressions of silence information regulator 1 (Sirt1) mRNA were investigated with quantitative real time polymerase chain reaction (PCR).Results The levels of Sirt1 mRNA were significantly increased in SCLE B cells relative to healthy controls (P ＜ 0.01).Conclusions Histone modifications appear abnormal in B cells in SCLE.

Objective To optimize the method and condition s for the extraction process of Fushuning Granules.Methods Different factors and levels were in vestigated by orthogonal design wit h yields of oleanolic acid and tanshi noneⅡ A as the markers.The yields of effective com ponents by percolation and reflux we re compared.Results The extraction ratio by re-flux was higher than that by percolation.The primary factors influencin g extraction ratio by reflux were the pulverization degree of medicinal materials,concentration of alcohol,refluxing times and refluxing perio d.Conclusion The opti-mum extraction process was:refluxing and extracting the pulverized med icinal materials for 3times(1hours each time )with 6-fold 90%alcohol added in the f irst time and then 5-fold in the secon d and the third time.

Objective To explore the effect of advanced glycation end products(AGEs) on the oxidative stress in porcine vascular endothelial cells(PIECs). Methods After being intervened by AGEs for some time,cell viability was detected by MTT.2′,7′-dichlorofluorescein diacetate(DCFH-DA) was used as a reactive oxygen species(ROS) capture agent.The fluorescent intensity of 2′,7′-dichlorofluorescein(DCF),which was the product of cellular oxidation of DCFH-DA,was detected by flow cytometry,and the level of ROS was thus measured. Results Viability of PIECs was inhibited by AGEs in a dose-and time-dependent fashion(P

BACKGROUND:Ankylosing spondylitis is an autoimmune disease involved in chronic systemic inflammation. Tumor necrosis factor and interleukin-6 levels increased in patients with ankylosing spondylitis. Inflammatory factors such as tumor necrosis factor and interleukin-6 can suppress CD36 expression in monocytes. OBJECTIVE: To analyze the correlation between CD36 expression in monocytes and ankylosing spondylitis. METHODS:A total of 84 newly diagnosed ankylosing spondylitis patients and 111 healthy individuals were included in this study. CD36 expressions in monocytes in ankylosing spondylitis patients and healthy individuals were tested using flow cytometer; meanwhile, biochemistry, immunology, routine blood examination and related inflammatory markers were determined between the two groups. RESULTS AND CONCLUSION:Results of baseline data in both groups demonstrated that CD36 fluorescence intensity in monocytes was significantly lower in patients with ankylosing spondylitis compared with healthy controls (P < 0.01). CD36 fluorescence intensity in monocytes was negatively correlated with C-reactive protein, erythrocyte sedimentation, interleukin-6 and tumor necrosis factor. In addition, CD36 fluorescence intensity in monocytes was negatively correlated with BASDAI score. Logistic regression analysis showed that erythrocyte sedimentation, interleukin-6, tumor necrosis factor and CD36 fluorescence intensity in monocytes were associated with ankylosing spondylitis, and risk factors for ankylosing spondylitis (P < 0.05). These findings confirm that inflammatory cytokine in patients with ankylosing spondylitis weakened the expression of CD36 in monocytes. There was a remarkable association between low expression of CD36 expression in monocytes and ankylosing spondylitis. CD36 expression of monocytes clinicaly may be considered to be an effective indicator to evaluate inflammation and disease activity in patients with ankylosing spondylitis.

The languages, types and number of digital resources in 8 domestic medical and pharmaceutical college and university libraries were analyzed , which showed that although certain successes have been achieved in devel-opment of digital resources in these libraries, there are some problems needing to be solved, such as weakness in new digital resources development , insufficient integration of free and open access resources , insufficient organiza-tion and revealing of resources .Suggestions were put forward for the solution of these problems , such as optimizing digital resource structure, developing characteristic digital resources, sufficient organizing and revealing digital re-sources.

Objective To evaluate the long-term clinical outcome of percutaneous coronary intervention ( PCI) with drug-eluting stents ( DES) for distal unprotected left main coronary artery (ULMCA) lesions. Methods Between Jan 2005 and Dec 2009, 111 patients with distal ULMCA disease who underwent drug-eluting stents implantation were enrolled in this retrospective study. The primary end points were major adverse cardiac and cerebrovascular event (MACCE) at follow-up, including death, non-fatal myocardial infarction, cerebrovascular event and target lesion revascularization ( TLR) . Results Patients were 65. 6 ± 10 years old. 21. 6% were diabetic. 31. 5% of the left main bifurcations were classed as Medina 1, 1, 1. Provisional T stent technique was performed for 79. 3% of the population. 30. 6% of cases underwent angiography follow-up. The median follow-up time was 2. 3 years, the MACCE-free survival was 87. 4% and the estimated freedom from TLR was 94. 6% . Diabetes mellitus was identified as the predictor of TLR. Conclusions PCI with DES for distal ULMCA disease was safe and effective when the strategy was made based on the case-by-case assessment.
