Evaluation of safety and efficacy of elective PCI in patients with cardiac insufficiency.

We analyzed the safety and the efficacy of the treatment with elective percutaneous coronary intervention (PCI) in patients with coronary heart disease complicated with cardiac insufficiency. We enrolled 217 patients diagnosed with chronic ischemic heart disease complicated with cardiac failure. According to the type of treatment they received, patients were divided into 3 groups: i) The conservative treatment group with 60 patients (they received standard medication); ii) the early PCI group with 82 cases (their condition was stabilized, surgical risk was assessed and PCI was taken as early as possible); and iii) the advanced PCI group with 75 cases (ischemic myocardium was corrected and then elective PCI was applied and for aggravated myocardial ischemia cases, PCI was applied after assessing the risk of surgery).

Reinforcing effect of calcium sulfate cement bovine bone morphogenetic protein on vertebral in the rabbit model of osteoporosis.

Objective: To observe reinforcing effect of calcium sulfate cement (CSC) bovine bone morphogenetic protein (bBMP) on vertebral in the rabbit model of osteoporosis.

Methods: A total of 48 New Zealand white rabbits were randomly divided into group I (blank control group), group II (CSC injection group), group III (CSC/bBMP injection group) and control group. White rabbit osteoporosis model was established rapidly by using castration method+methylprednisolone candidate.

Neuroprotective effect of Jatrorrhizine on hydrogen peroxide-induced cell injury and its potential mechanisms in PC12 cells.

The neuroprotective effects of Jatrorrhizine from Coptidis Rhizoma against hydrogen peroxide (H(2)O(2))-induced rat pheochromocytoma line PC12 injury and its potential mechanisms were evaluated in the present study. When cells were exposed to H(2)O(2) (200 μM) for 12h, there was a significant reduction in cell survival and activity of antioxidant enzyme (SOD and HO-1) and LDH release. In addition, increased ROS production, declined MMP and increased production of malondialdehyde (MDA) were observed.

EFEMP1 expression promotes angiogenesis and accelerates the growth of cervical cancer in vivo.

Objective: The study was to investigate the role of EFEMP1 in angiogenesis and growth of cervical carcinoma in vivo.

Methods: Effects of EFEMP1 on proliferation of Hela cells and HUVECs, invasion of Hela cells and migration of HUVECs, and adhesion of Hela cells to HUVECs were evaluated by MTT, Transwell chamber assay and adhesion assay, respectively. EFEMP1 overexpression in Hela cells was achieved by stable EFEMP1 gene transfection into Hela cells by Lipofectamin™ 2000 and the effectiveness of transfection was verified with western-blotting.

The expression of EFEMP1 in cervical carcinoma and its relationship with prognosis.

Objective: The study was to explore the role of EFEMP1 protein in angiogenesis and its relationship with prognosis of cervical carcinoma.

Methods: EFEMP1 expression was evaluated by immunohistochemistry. The microvascular density (MVD) was detected with CD34 staining, and VEGF mRNA expression was evaluated by hybridization in situ.
