This study was aimed to explore effect of Gui-Zhi Fu-Ling W an (GZFLW) on HIF-1α and vascular en-dothelial growth factor (VEGF) in patients with endometriosis. A total of 68 endometriosis patients in the First Peo-ple's Hospital of Xining from June 2011 to June 2013 were included. All patients received treatment of GZFLW, once a day. After one-month treatment, the treatment efficacy was analyzed. The endometrial tissues (both ectopic endometrium and eutopic endometrium) were obtained before and after treatment. The protein levels of HIF-1α and VEGF as well as the relationship of HIF-1α and VEGF were analyzed by SP immunohistochemistry. The results showed that the total treatment efficacy was 86.76%. Compared with pretreatment, the posttreatment protein levels of HIF-1α and VEGF were significantly reduced (P< 0.05). The decreasing of VEGF protein level and HIF-1α expres-sion level were positively correlated (P< 0.05). It was concluded that GZFLW had better efficacy in the treatment of endometriosis. One of the reasons may be the downregulation of protein levels of HIF-1α and VEGF in endometriosis tissues.

Ultrasonography is a simple and reliable non-invasive method in tumor vascularity detection of breast neoplasms. Tumor vascularity morphometric and topological characteristic in breast neoplasms provides an important basis for differentiation between benign and malignant lesions. Studies indicate that visual blood vessel shape and direction, velocity, properties of blood flow can be satisfactorily shown by color Doppler flow imaging(CDFI). But CDFI is confined by the angle between acoustic beam and blood flow. Power Doppler ultrasound (PDU) can overcome the difficulties mentioned above, but can not offer the information of blood velocities and motion error. The intratumoral flow features can clearly and visually shown by three-dimensional ultrasonography (3DUS) and contrast- enhanced ultrasound (CEUS). 3 DUS and CEUS will be new potential diagnosis techniques in vascularity estimation of breast neoplasms.

OBJECTIVE:To observe the clinical efficacy and safety of Kudiezi injection combined with alprostadil in the treat-ment of posterior circulation ischemic vertigo. METHODS:Totally 180 patients with posterior circulation ischemia were randomly divided into group A,group B and group C. All patients were given aspirin,atorvastatin,nutrition nerve,antihypertensive,hypo-glycemic and other conventional treatment. On this basis,group A was given Alprostadil injection 10 μg,adding into 0.9% Sodium chloride injection 100 ml,iv,once a day;Kudiezi injection 30 ml,adding into 0.9% Sodium chloride injection 250 ml,iv,once a day. Group B was given Alprostadil injection(the same usage as group A);group C was given Kudiezi injection(the same usage as group A). The course was 14 d. The clinic data was observed,including clinical efficacy;blood flow velocity in left vertebral ar-tery(LVA),blood flow velocity in right vertebral artery(RVA),blood flow velocity of basilar artery(BA),changes of peak laten-cy(PL)and incubation period latency(IPL)before and after treatment;and the incidence of adverse reactions. RESULTS:The to-tal effective rate in group A was significantly higher than group B and C,with significant difference(P<0.05). After treatment,the blood flow velocity of LVA,RVA and BA in each group were significantly higher than before,group A was higher than group B and C;PL-Ⅰ,PL-Ⅲ,PL-Ⅴ,IPL-Ⅰ-Ⅲ and IPL-Ⅲ-Ⅴ were significantly lower than before,group A was lower than group B and C,with significant differences(P<0.05);however,there were no significant difference between group B and C(P>0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Kudiezi injection combined with alprostadil has better effica-cy than only Kudiezi injection or alprostadil in the treatment of posterior circulation ischemic vertigo,with good safety.

The remodeling and reparative process post myocardial infarction (MI) can be divided into three phases:the inflammatory phase,the proliferative phase and the stable phase.The inflammatory immune response plays an important part in the process of cardiac remodeling.First of all,the initiation of inflammatory response relies on the activation of innate immunity with a group of pro-inflammatory cytokines,chemokines and adhesion molecules.These molecules lead to the infiltration of the infarct area with neutrophils and mononuclear cells,further clearing the wound from dead cardiomyocytes and matrix debris.After resolution of inflammatory response,reparative cells and cytokines infiltrate into the heart and promote the differentiation and growth of myofibroblasts and endothelial cells,contributing to wound contraction as well as producing fiber tissue to form a scar.Moreover,overactive immune responses could accentuate infarct injury and dilative remodeling while deficiency of inflammation leads to insufficient repair,which highlights the dual function of the immune response in myocardial injury and repair post MI.Also the intense immune response along with fibrosis in non-infarct area is also closely associated with adverse remodeling.Thus,targeting specific factors in the inflammatory reaction may hold promise in patients with MI.

Objective To summarize the clinical experience of serious hyponatremia resulted from applying pitnitrin to massive hemorrhage of gastrointestinal tract patients.Methods we used pitritrion on 2460 such patients and examined some symptoms of the digestive tract and nerve system,monitoring the dynamic state of blood sodium.Results The re- suits reveal that patients in 30 cases turned out to suffer from serious hyponatremia,whese sodium in the serum appeared less than 110 mmol/L,which was 1.22% of the rest subjects'.The relevant symptoms included nausea,vomit,spoor,coma and twitch etc.Following remedies included liquid supply with a high-concentrated sodium,ceasing using pituitrin,in- take of salute foods,and dynamic monitoring on the state of sodium in the serum.All patients recovered in 1 to 3 days without a single failure.Conclusion Thus we reach this conclusion:When applying pituitrin to massive hemorrhage of gastrointestinal tract patients,the above mentioned symptoms should be closely examined,and blood sodium should be timely monitored so that proper treatment should arrive in time.

Brain-targeting non-viral gene delivery systems could efficiently mediate gene drugs to cross blood-brain barrier and reach the diseased regions. Many researches have demonstrated that enhanced brain accumulation and gene expression could be achieved via appropriate mechanisms such as specific ligand-receptor binding function. In this review, progress on brain-targeting non-viral gene delivery systems mainly based on receptor- and adsorptive-mediated mechanisms is reviewed.

To construct recombinant reporter plasmids containing different Alpha gene segments and Alpha1-TFEB fusion gene and to evaluate the promoter activity of the Alpha gene. Methods:Promoter regions of the Alpha gene were predicted using a software Primer 0.5. Five Alpha gene segments with different lengths and a normal TFEB gene promoter (pTFEB) were amplified via polymerase chain reaction, and recombinant reporter plasmids containing different Alpha gene segments and a normal TFEB gene pro-moter were constructed. Liposome transfection was used to transfect these vectors into the human embryo kidney 293T cells. The pro-moter activity of the Alpha gene was evaluated via luciferase assay. Meanwhile, the recombinant Alpha1-TFEB plasmid was construct-ed and transfected into the 293T cells. The TFEB expression of the recombinant Alpha1-TFEB plasmid was then detected via Western blot. Results: Recombinant reporter plasmids containing different Alpha gene segments and pTFEB were constructed successfully. Compared with the luciferase activity of pGL3-Basic, that of the groups with Alpha1, Alpha2, Alpha3, Alpha4 and Alpha5 significantly increased (P<0.01). The luciferase activity also increased significantly in the groups with Alpha1, Alpha2 and Alpha5 compared with that of the pTFEB group (P<0.01). The TFEB expression of the pGL3-Enhancer-Alpha1-TFEB was significantly higher compared with that of the pGL3-Enhancer group. Conclusion:In t(6;11) translocation RCC, the Alpha gene has a strong promoter activity and it en-hances TFEB expression. The strongest promoter activity region is in Alpha5 with a sequence from 643 bp to 693 bp.

Objective To assessed the image quality and diagnostic value of the coronary artery diseases with 64-slice spiral computed tomography (64-SCT) angiography. Methods A retrospective image analysis of 39 patients who were diagnosed with coronary heart disease by both the 64-SCT and the invasive coronary angiography (CAG). Results In 507 coronary artery segments (13 coronary segments for each patient),1-,2-,3-class image quality by 64-SCT were in 185 (36.5%),236 (46.5%),86 (16.9%) segments respectively,and the heart rate range was respectively 62?5,66?4 and 75?10 per minute. Totally 421/507 (83.1%) segments that were of 1-,2-class image quality,met the requirements of clinical diagnosis,whereas 86/507 (16.9%) segments could not be sufficiently evaluated because of severe calcifications (51/86,59.3%) and/or motion artifacts (35/86,40.7%). Taking CAG as the gold standard diagnostic technique for coronary heart disease,of the lesions≥50% stenosis by 64-SCT (without any exclusion criteria),the overall sensitivity,specificity,accuracy,positive predictive value,and negative predictive value were 89.8%,94.9%,93.3%,88.5%,95.5%,respectively. Conclusion Our results indicate high diagnostic accuracy of coronary artery disease by 64-SCT compared to CAG. 64-SCT is a simple,convenient,safe and reliable,non-invasive effective method for diagnosis of coronary heart disease.
