Objective To investigate the effect of music electroacupuncture on perifocal ferric ions and neuronal apoptosis and the brain water content in rats with acute cerebral hemorrhage and explore the mechanism of its action on acute cerebral hemorrhage.Methods One hundred and twenty-eight healthy adult male Wister rats were randomized to normal, model, electroacupuncture and music electroacupuncture groups. In each group, four time points of 6 hrs, 24 hrs, 3 days and 7 days were set up, eight rats each time point. A rat model of acute cerebral hemorrhage was made using collagenase. In the electroacupuncture and music electroacupuncture groups, point Baihui was connected to the anode and point Taiyang to the cathode, 2 voltage was used as a selection parameter and electroacupuncture lasted 30 min. Intracerebral perifocal ferric ions and neuronal apoptosis and the brain water content were measured at four time points of 6 hrs, 24 hrs, 3 days and 7 days after model making.Results Intracerebral ferric ion content was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrsafter model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 24 hrs, 3 and 7 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 3 and 7 days after model making (P<0.05). Intracerebral neuronal apoptosis was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrs after model making (P<0.05) and lower in the music electroacupuncture group than in the electro- acupuncture group at 7 days after model making (P<0.05). The brain water content was higher in the model, electro- cupuncture and music electroacupuncture groups of rats than in the normal group at 6 and 24 hrs after model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 3 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 7 days after model making (P<0.05).Conclusions Music electroacupuncture has a benign regulating effect on intracerebral perifocal ferric ions, inhibits neuronal apoptosis around hematoma in the early stage and reduces cerebral edema in rats with acute cerebral hemorrhage. Its therapeutic effect is superior to that of electroacupuncture.

Objective To study the effects of Astragalus and Thoroughfare Oral Liquid(ATOL) on the immunological functions of the immunosuppressive mice induced by hydrocortisone (HC). Methods A total of 50 mice were divided into 5 groups randomly. Mice in 4 groups were immunosuppressive animal model induced by HC, then ATOL (0.2, 0.1 and 0.05mL/10g) was administered to 3 groups of them. The phagocytotic function of peritoneal macrophage, the proliferation rate of T cells in spleen, and the cytotoxicity of NK cells in spleen, and the production of antibodies and IL-2 by spleen cells were examined to evaluate the immunological function of mice. Results Different doses of ATOL could improve the phagocytotic function of peritoneal macrophage, the proliferation rate of T cells in spleen and the cytotoxicity of NK cells. The drug could also promote antibody formation as well as IL-2 in the immunosuppressive mice. Conclusion ATOL can evidently improve some of the immunological functions in HC-induced immunosuppressive mice.

Objective To evaluate the protective effects of oxymatrine injection on rats with endotoxic shock. Methods Wistar rat model of endotoxic shock was produced in this study. Twenty-four Wistar rats were randomly divided into normal control group (n=8), endotoxic shock group (n=8) and oxymatrine injection treatment group (n=8). Fifteen min?utes after the infusion of LPS (15 mg/kg) from femoral vein, oxymatrine was injected from femoral vein in treatment group, then we observed the mean arterial pressure (MAP) for six hours. At the end of experiment blood samples were harvested for measurement of urea and creatinine (Cr), which reflect renal function. Also contents of IL-6, IL-10, TNF-αin the renal ho?mogenate were detected. Results Oxymatrine can prevent progressive decrease of MAP in endotoxin shock treatment group. The contents of plasma urea and Cr were significantly higher in endotoxin shock group than those of control group. The contents of IL-6, IL-10 and TNF-αin renal homogenate increased obviously, but after the injection of oxymatrine, the contents of urea and Cr significantly decreased in treatment group, also IL-6 and TNF-α were significantly declined. Conclusion Oxymatrine provides protection at renal function after endotoxin shock, and its mechanism may be related to inhibit the releasing of inflammatory cytokines in kidney.

Objective To investigate the infect capability of recombinant adenovirus mediated PDGF to human umbilical cord derived mesenchymal stem cells (MSCs). Methods The PDGF cDNA sequence was amplified with RT-PCR and constructed recombinant adenovirus vector AdPDGF. The human umbilical cord derived MSCs were isolated and cultured. In vitro AdPDGF infected MSCs with various MOI,and determine the efficiency using FACS and fluorescence microscope. Trypan blue and MTT assay was used to detect cell viability and proliferation. ELISA was used to quantify PDGF secretion. Results Recombinant adenovirus AdPDGF was successfully and constructed,in which infection efficiency to MSCs was dose dependent. The highest efficiency was around 87.36 % when MOI =50,at which cell viability and proliferation wasn' t impaired. Cell viability of uninfected,AdPDGF infected and control virus infected MSCs was (97.8 ±2.3) %,(91.9±4.0) % and (92.8±4.0) %,separately. The cell proliferation was (100±16.8) %,(95.9±12.0) % and (87.5±9.7) %,separately. There was no statistic significance among AdPDGF infected,control virus infected and uninfected MSCs. 48 hrs post infection,PDGF secretion can be measured from infectious MSCs' supernatant. The secretion level was (1.53±0.37),(3.03±0.68) and (5.25±0.92) ng/ml,separately,when MOI= 10,30,50. No PDGF can be detected from MSC-GFP and control MSC group. Conclusion Recombinant adenovirus AdPDGF was constructed and can infect human umbilical cord derived MSC at high efficiency.

Objective To evaluate the clinical value of CT perfusion (CTP) imaging for providing quantitative information about angiogenesis in patients with lung carcinoma and investigate the correlation of CTP enhancement parameters and histological microvessel density (MVD) with lymphatic involvement in peripheral lung carcinoma. MethodsFifty-three patients with pathology-proved peripheral lung carcinoma underwent CT perfusion scan before operation. The enhancement parameters of CTP were calculated based on the time-density curves (TDC) of fist pass phase. All cases were classified into two groups according to pathologic results: tumor with and without lymph node involvement. Two-sample t test was used for the statistics. The ROC curve was used to assess the efficiency of the enhancement parameters of CT perfusion and MVD for predicting lymphatic involvement.Results Tumors with lymph node involvement had significantly higher value of MVD than those without lymph node involvement (64.69±16.34 and 42.67± 16.78, respectively,t=4.84,P<0.01). Tumors with lymph node involvement had significantly higher value of CTP enhancement parameters (PH, M/A, PV) than those without lymph node involvement [PH= (41.79±15.50) and (29.99±10.91) HU,M/A =0.24±0.09 and 0.15±0.06, PV=(2.14±1.09) and (1.27±0.53) ml·min~(-1)·ml~(-1), t=3.21,3.95, 3.66, P<0.01, respectively]. The CTP enhancement parameters (PH, M/A, PV) of lung cancer correlated positively with the MVD, the highest correlation coefficient was between the PV and MVD (r=0.716, P<0.01). MVD and PV had higher values for predicting lymph node involvement in ROC curve analysis.The sensitivity, specificity and accuracy for predicting lymph node involvement were 80.8%, 81.5% and 81.1% or 84.6% ,85.2% and 84.9% respectively if MVD>52/0.74 mm~2 or PV>1.52 ml·min~(-1)·ml~(-1). ConclusionThe CT perfusion PV and histological MVD have good correlation with lymph node involvement in peripheral lung carcinoma and are important predicting parameters before operation.

ObjectiveTo investigate the effect of vasostatin on the migration of pancreatic cancer endothelial cells.Methods Ad-vasostatin with different concentrations of vasostatin was used to transfect pancreatic cancer endothelial cells.Ad-LacZ transfection and PBS was used as control.The effect of vasostatin gene mediated by adenovirus on the migration of pancreatic cancer endothelial cells was measured by woundhealing assay,transwell migration assay,and tube formation assay.ResultsThe scratched lines in PBS group and Ad-LacZ group were almost healed 48 hours later,while the lines in Ad-vasostatin group were rarely healed.At the MOI of 1,2,5,the migration rate of Ad-Laz group was ( 84.7 ± 2.6) ％,(80.7 ± 1.7 ) ％ and (81.3±4.0)％,while the corresponding values were (77.7 ±2.1)％,(67.3 ±2.1)％ and (38.8 ±2.1 ) ％ in Ad-vasostatin group.Transwell migration assay indicated that the number of migrated cells in Advasostatin group was inhibited in a dose-dependant manner,at the MOI of 5,the migration became significantly decreased (F=180.88,P ＜0.05).At the MOI of 1,5,10,the number of tubes in Ad-LacZ group was 118±6,120±6 and 82±5,while the corresponding values were 65±4,21±4 and 4 ±1 in Ad-vasostatin group.The number of tubes of pancreatic cancer endothelial cells was inhibited by Ad-vasostatin in a dose-dependant manner,at the MOI of 10, it was difficult to form the tubes (F-300.85,P＜0.05). Conclusions The vasostatin gene mediated by adenovirus has a significant inhibitory effect on the migation of pancreatic cancer endothelial cells in vitro in a dose-dependent manner.

Objective This study aims to investigate the moral disgust cognitive processing of patients with obses?sive-compulsive disorder (OCD) and its relationship with OCD symptoms. Methods Twenty-eight OCD and 30 healthy controls matched for gender, age and education completed lexical decision task, recording reaction time and accuracy of words and assessing the degree of disgust. Yale-Brown obsessive-compulsive scale (Y-BOCS) and Padua Invento?ry-Washington State University Revision (PI-WUSR) were used to assess the symptoms. Results OCD group showed significantly longer reaction time to core disgust-related words [(762.69 ± 128.25) ms vs. (648.69 ± 162.66) ms] and moral disgust-related words [(798.73 ± 115.26) ms vs. (727.00 ± 106.06) ms] than the healthy controls (P<0.05). OCD group showed significantly higher aversion degree to core disgust-related words [(6.38 ± 1.78) vs. (5.03 ± 1.64)] and moral dis?gust-related words [(7.08 ± 1.23) vs. (5.77 ± 1.44)] than control group (P<0.05). Y-BOCS total score, Y-BOCS obsessive thoughts score, Y-BOCS compulsive behavior score, total score of PI-WUSR, cleaning/pollution force factor score, hurt?ing themselves and others force factor were positively correlated with two types of disgust-related words in patients group (P<0.05). Multiple stepwise regression analysis between disgust words and Y-BOCS/PI-WUSR scores pointed that only CWCF influenced disgust degree of core disgust-related words (β=0.61, P<0.01) and moral disgust-related words (β=0.54, P<0.01), respectively. Conclusion The core disgust and moral disgust of OCD are stronger compared to controls.
