Objective To study the anti-injury effects of grape seed proanthocyanidin (GSP) on the umbilical vein endothelial cell (HUVEC)injured by hydrogen peroxide(H2O2) and its mechanism. Method Oxidative damage model of endothelial cell was induced by H2O2,and the cells were divided into five groups,including normal groups,oxidative damage group and three (100,50,10 ?g/ml) GSP pretreated groups. MTT assay was used to detect the protection of GSP,Reverse transcription PCR (RT-PCR) was used to detect the protein expression in mRNA level of monocyte chemoattractant protein (MCP-1) and flow cytometry(FCM) was used to detect apoptosis rate and quantitate the expression of intercellular adhesion molecule(ICAM-1)and vascular cell adhesion molecule ( VCAM-1). Results The cell optical density in oxidation damaged group was lower than that in normal control. When pretreated by GSP,the OD value was increased,and was insignificantly different between high GSP group and normal control. In H2O2 damage group,the expression of MCP-1 mRNA and the apoptosis rate were increased,and the numbers of positive cells which express ICAM-1 or VCAM-1 were obviously more than those in pretreated groups respectively.Futhermore,these effects were dose dependent. Conclusion GSP has the protective effect on oxidative damage of HUVEC. The mechanism may be related to stabilization of cell wall and inhibition of inflammatory reaction and apoptosis induced by ICAM-1,VCAM-1 and MCP-1.

Objective:To compare the suicidality risk in major depressive disorder (MDD)patients with and without anxious characteristics,and analyze the risk factors of suicidality in MDD patients. Methods:This was a secondary analysis of the data from the Diagnostic Assessment Service for people with Bipolar Disorders in China (DASP),which was initiated by the Chinese Society of Psychiatry (CSP),from September 1,2010 to February 28, 201 1. Based on the anxious module and suicide module of Mini International Neuropsychiatric Interview (M. I. N. I),1 172 MDD patients were classified as suffering from anxious MDD (n=728,62. 1%)and non-anxious MDD(n=444,37. 9%). Logistic regression was employed to examine the risk factors of suicidality in MDD pa-tients. Results:Among the anxious MDD patients,331 (45. 5%)of them had suicidality risk. And 54(12. 2%)of non-anxious MDD patients had suicidality risk. Compare to the non-anxious group,the anxious MDD patients had significantly higher suicidality risk (P<0. 00 1 ). Logistic regression analysis showed that more frequent depressive episodes (OR=2. 07 ),depressive episodes with psychotic symptoms (OR=2. 0 1 ),comorbid with anxious charac-teristics (OR=3. 18)or melancholic characteristics (OR=2. 90)were associated with suicidality risk in patients with MDD. Conclusion:It indicates that the anxious MDD patients may have higher suicidality risk than non-anx-ious MDD patients,and more frequent depressive episodes,depressive episodes with psychotic symptoms,comorbid with anxious characteristics or melancholic characteristics may be risk factors of suicidality in patients with MDD.

Objective To analyze the risk factors of socio-demographic and clinical characteristics related to sui?cide risk in misdiagnosed bipolar disorderⅡ(BPⅡ) treated for major depressive disorder. Methods A total of l478 con?secutive major depressive disorder patients were interviewed with the Mini International Neuropsychiatric Interview (MINI) in 13 major mental health centers in China. Of the 1478 patients, 190 patients were diagnosed BPⅡ, who were divided into two groups (nonsuicidal risk and suicidal risk) with the suicidality module of MINI. Logistic regression was performed to evaluate significant risk factors associated with suicide risk in misdiagnosed BPⅡtreated for major depres?sive disorder. Results Of the 190 patients, 116 were in the nonsuicidal risk group and 74 were in the suicidal risk group. In comparison to the nonsuicidal risk group, the suicidal risk group had younger age [(34.45 ± 11.18) vs.(37.23 ± 13.22), P=0.008], earlier age at onset [(26.20 ± 9.16) vs. (30.37 ± 11.59), P=0.007], and more suicidal ideation (82.4%vs. 53.4%, P=0.001). Logistic regression analysis showed that age (OR=0.969,95% CI:0.945~0.993) and depressive epi?sodes with suicidal ideation (OR=4.129,95%CI:2.030~8.397) were significantly associated with suicide risk in patients of misdiagnosed BPⅡtreated for major depressive disorder (P<0.05). Conclusions Younger age, severer suicidal ide?ation may be potential independent risk factors to suicide risk in BPⅡwith misdiagnosed with major depressive disor?der.

To investigate the effect of serine/threonine-protein kinase B-Raf (BRAF)-activated long-chain non-coding RNA (lncRNA-BANCR) on apoptosis and autophagy in thyroid carcinoma cells and the underlying mechanisms.
Methods: RT-PCR was used to detect the expression of lncRNA-BANCR in thyroid carcinoma and normal thyroid tissues. The association between lncRNA-BANCR and clinicopathological data was analyzed in patients with thyroid cancer. Cell counting kit-8 (CCK-8) was used to detect the effect of lncRNA-BANCR on the proliferation of thyroid cancer cells. The effect of lncRNA-BANCR on the apoptosis of thyroid carcinoma cells was detected by flow cytometry. Transwell invasion assay was used to detect the effect of lncRNA-BANCR on the invasive ability of thyroid cancer cells. Western blot was used to detect the changes of autophagy proteins LC3-I and LC3-II after the lncRNA-BANCR expression was suppressed.
Results: Compared with normal thyroid tissues, the expression level of lncRNA-BANCR in thyroid carcinoma tissues was elevated (P<0.05). The expression of lncRNA-BANCR was positively related to the pathological stage of thyroid carcinoma and the lymph node metastasis. Inhibition of lncRNA-BANCR expression attenuated the proliferation and invasion ability of thyroid cancer cells (both P<0.05); but the apoptosis was enhanced (P<0.05); the expression levels of autophagy protein LC3-I and LC3-II were also increased (P<0.05).
Conclusion: The expression level of lncRNA-BANCR affects the proliferation, invasion and apoptosis of thyroid cancer cells through modulation of autophagy behavior.

ObjectiveTo establish the specific chromatogram and thin layer chromatography(TLC) identification method of Kaixinsan(KXS) samples, in order to clarify the key quality attributes and provide reference for the quality evaluation of KXS. MethodHigh performance liquid chromatography(HPLC) specific chromatogram of KXS was developed with YMC Hydrosphere C18 column(4.6 mm×250 mm, 5 μm), the mobile phase was acetonitrile(A)-0.2% formic acid aqueous solution(B) for gradient elution(0-15 min, 2%-20%A; 15-25 min, 20%-25%A; 25-30 min, 25%-30%A; 30-45 min, 30%-31%A; 45-50 min, 31%-44%A; 50-65 min, 44%-45%A; 65-73 min, 45%-75%A; 73-95 min, 75%-100%A; 95-105 min, 100%A; 105-105.1 min, 100%-2%A; 105.1-120 min, 2%A), the detection wavelength was 320 nm. Ultra high performance liquid chromatography-linear ion trap-electrostatic field orbitrap mass spectrometry(UHPLC-LTQ-Orbitrap MS) was used to identify the chemical components of KXS with electrospray ionization(ESI), negative ion mode and scanning range of m/z 50-2 000. TLC identification methods for Poria and Ginseng Radix et Rhizoma in KXS were established. ResultThere were 11 common peaks in the specific chromatogram of KXS, attributed to Polygalae Radix, Poria and Acori Tatarinowii Rhizoma. Taking peak 9(α-asarone) as the reference peak, the relative standard deviations of the retention times of 15 batches of KXS samples were<0.2%. A total of 34 compounds were identified by UHPLC-LTQ-Orbitrap MS, including terpenoids, phenylpropanoids, oligosaccharides and ketones. The established TLC had good separation and was rapid, reliable, simple, feasible, suitable for the identification of Poria and Ginseng Radix et Rhizoma in KXS. ConclusionThe specific chromatogram and TLC of KXS are stable and reproducible. The material basis of KXS is basically clarified by MS, which can provide a reference for the development and quality control of KXS.
