The neurogenic pulmonary edema (NPE) was produced consistently in rabbits by raising intracranial pressure (ICP) with an infusion of anticoagulat rabbit blood into subarachnoid space of the bilateral parietal regions. When ICP increased from 60mmHg to 140 mmHg, There was a rapid decrease in blood flow volume of the bilateral internal carotid arteries (ICABFV). At the same time, the frequency of cervical sympathetic discharge and the concentrations of plasma noradrenaline and adrenaline increased acutly accompanied by a rapid elevation of systemic arterial pressure (SAP). There was a decline in SAP and a further decrease in ICABFV and the animal died as ICP was sustained at 140mmHg for 5-20min. Autopsy revealed severe hemorrhagic pulmonary edema and the left ventricular and atrial enlargement. In the period of ICP rising, the NPE was prevented if SAP was kept at the baseline levels by withdrawing blood from femoral artery, The results suggest that decreased cerebral blood supply due to ICP rising is responsible for the massive sympathetic discharge and catecholamine release which contribute to SAP elevtion and left ventricular overload, the NPE is mediated by hemodynamic mechanism.

Objective To analyse the clinical usage of Shenmai injection, promote the rational use of Shenmai injection. Methods 400 hospital medical records that used Shenmai injection in 2015 were collected and reviewed from hospital information system (HIS) by retrospective analysis method, aggregated and evaluated data by EXCEL. Results In 400 cases, 11 clinical departments used the Shenmai injection, mainly in cardiology of 347 cases(86.75%).The percentage of the non-standard clinical application of Shenmai injection was 84 cases (21.00%). The non-standardized rates of solvent dispensing was 287 cases (71.75%), and the specification incompatibility accounted for 105 cases (26.25%). There was no adverse drug reaction of Shenmai injection. Conclusion The clinical use of Shenmai injection is not yet standardized, which suggests that drugs should be strictly used in accordance with the instruction, in order to avoid risks of off-label use.

Pituitary stalk interruption syndrome(PSIS) is a rare disease characterized by different degrees of anterior pituitary hormone deficiency.The typical imaging finding is a thin or absent pituitary stalk,often associated with an ectopic posterior pituitary and a hypoplastic anterior pituitary.The cause is still unkown.Dynamic contrastenhanced MRI helps to confirm the diagnosis.Replacement of multiple anterior pituitary hormones is the key of the treatment.Doctors should have a thorough understanding of the disease and give patients efficacious treatment and a better prognosis would be obtained.

Objective: To observe the effect of extracorporeal shock wave therapy (ESWT) on proliferation, cell cycle and intercellular adhesion molecule-1 (ICAM-1) expression in human umbilical vein endothelial cells (HUVECs). Methods: HUVECs were culturedin vitro at the concentration of (1×105/ml) and the cells were divided into 2 sets of groups:CSWT group, the cells were treated by different energy of (0.03, 0.09, 0.18, 0.24) mJ/mm2 respectively and corresponding Control group, in which the cells had no CSWT. HUVEC proliferation was detected by CCK colorimetric method, cell cycle was measured by lfow cytometry, mRNA and protein expressions of ICAM-1 were examined by RT-PCR and Western blot analysis respectively. Results: Compared with Control group, (0.09 mJ/mm2) CSWT group had promoted HUVECs proliferation,P<0.05 and the other CSWT groups were similar to corresponding Control groups,P>0.05; (0.09 mJ/mm2) CSWT group showed decreased proportion of G0/G1 stage and increased S and G2/M stages, allP<0.05; while (0.03 mJ/mm2) CSWT group only increased the proportion of G2/M stage,P<0.05 and the other CSWT groups were similar to corresponding Control group,P>0.05. Compared with Control group, (0.09 mJ/mm2 ) and (0.03mJ/mm2) CSWT groups showed increased mRNA expression of ICAM-1 (9.27±0.95) vs (1.02±0.27),P<0.001 and (7.08±0.60) vs (1.02±0.27),P<0.01; (0.09 mJ /mm2) CSWT group had elevated protein expression of ICAM-1,P<0.05. Conclusion: ESWT especially at (0.09 mJ/mm2) may accelerate cell cycle transition from G0/G1 stage to S and G2/M stages, promote HUVECs proliferation and increase ICAM-1 expression which may play important roles in ESWT facilitated angiogenesis in vitro.

BACKGROUND:Studies have shown that extracorporeal shock wave therapy is an effective, safe, and non-invasive treatment for ischemic heart disease, which can improve angiogenesis in the ischemic myocardium. OBJECTIVE:To summarize the research advances in promotion of angiogenesis for ischemic myocardium by extracorporeal shock wave therapy. METHODS:A computer-based online search of PubMed database and CNKI database was performed for relevant articles published between 1998 and 2014 with key words of “shock wave, ischemic heart disease, angiogenesis, cytokine, stem cel” in English and Chinese, respectively. Articles related to the promotion of angiogenesis for ischemic cardiovascular disease by extracorporeal shock wave were selected. Repetitive articles were excluded. According to inclusion criteria, 51 literatures were selected in result analysis. RESULTS AND CONCLUSION: Extracorporeal shock wave therapy can improve angiogenesis in the ischemic myocardium by mobilizing proliferation and differentiation of stem cels into vascular endothelial cels, and by enhancing the expression of growth factors such as vascular endothelial growth factor and basic fibroblast growth factor. Moreover, the extracorporeal shock wave therapy can create a local favorable microenvironment for angiogenesis by inhibiting inflammation, oxidative stress and apoptosis and by regulating components of the extracelular matrix. Extracorporeal shock wave therapy plays an important role in the angiogenesis of ischemic myocardium and displays a good clinical prospect in the treatment of ischemic heart disease. However, the specific mechanism requires further studies.
