    AIM: To investigate the effect of gap junction in ischemic post-conditioning on cerebral ischemic-reperfusion injury in rats. METHODS: Sixty adult male SD rats were randomly divided into sham group, I/R group, IPO group, I/R+CBX group and IPO+CBX group. Thread occlusion method was used to make MCAO model. Neurological scores of rat were evaluated by Longa' score. Infarct volume of brain tissue was measured by TTC staining. Histopathology of cerebral tissue was detected by HE staining. The expressions of Cx43 and PKC protein were detected by Western Blot. RESULTS: In I/R group, neurological deficit scores decreased, cerebral infarction area increased and histopathology changed significantly, while similar changes did not found in sham group. IPO has protective effect on I/R injury. Similarly, CBX increased the protection of IPO on I/R injury obviously. Results of Western Blot showed, in I/R group, Cx43 protein increased significantly and PKC decreased compared to the sham group (P<0.01). Meanwhile, in IPO group Cx43 protein decreased extremely and PKC increased compared to I/R group. Similarly, in IPO+CBX group Cx43 protein decreased significantly and PKC increased compared to IPO group. CONCLUSION: IPO has protective effect on I/R injury through the gap junction, which may be associated with the change of PKC protein.

    AIM: To observe the effect of small molecule drug kartogenin (KGN) on promoting extracellular matrix secretion in endplate cartilage, and explore its protective role in the endplate cartilage or intervertebral disc degeneration. METHODS: Established an in vitro organ culture model of rat intervertebral disc, punctured the annulus and cultured in vitro. The rats were divided into three groups: control group, degeneration group and KGN treated group. The change of histomorphology in intervertebral disc tissue was assessed by HE staining, the extracellular matrix of endplate cartilage was observed by safranin O-fast green staining. The expressions of type Ⅱ collagen, proteoglycans and SOX-9 in the three groups were detected by Real time-PCR. The expressions of typeⅡCollagen and SOX-9 protein were measured by western blot.RESULTS: HE staining indicated that the nucleus disappeared and the endplate cartilage tended to thin in the degeneration group, and the disc structure is more complete after KGN treated; safranin O- fast green staining showed that the secretion of extracellular matrix were increased in the KGN treated group. Realtime-PCR showed type Ⅱcollagen, aggrecan, and SOX-9 mRNA levels were significantly reduced in the degeneration group, and the cartilage-related gene increased after KGN treated; Western blot results showed similar changes. CONCLUSION: Small molecule drug KGN can promote the extracellular matrix secretion in the endplate cartilage in order to protect the endplate cartilage and intervertebral disc degeneration.

    AIM: To explore the mechanism of L-securinine induced autophagy of human non small cell lung cancer A549 cell autophagy. METHODS: A549 cell lines were cultured in vitro and L-securinine at different concentrations (6.25,12.5,25,50,100,200 μmol/L) was added 24 h after cell lines were transferred. Then the plates were cultured for 24, 36 and 48 h. CCK-8 method was used to detect the antitumor effect of human non small cell lung cancer A549 in vitro. Inverted microscope was used to observe A549 cells treated with L-securinine morphological changes. The A549 cells were treated with different concentrations (0, 20 μmol/L) of L-securinine for 24 h.Then autophagy was analyzed by fluorescence microscope following staining with monodansylcadaverine (MDC). The mRNA levels of Beclin-1 were detected using real-time RT-PCR pre and post-treatment of L-securinine. RESULTS: The generation depression effects of A549 cells cultured in vitro were detected by CCK-8 method (P<0.05), and there were dosage-time dependent relationships. The morphology of cells become small and round, the process of cell division got less were observed. L-securinine-treated cells exhibited higher fluorescent density and more MDC-labeled particles in A549 cells compared with the control group. Beclin-1 expression enhanced with L-securinine concentration increased. CONCLUSION: L-securinine has an anti-tumor effect against human non small cell lung cancer A549 cell. The L-securinine can induce striking autophagy in A549 cell in vitro. The autophagy induced by L-securinine is related with upregulating the expression of autophagy gene Beclin-1.

    AIM: To examine the effect of recombinant human insulin-like growth factor-I(rhIGF-I) on the expression of matrix metalloproteinases (MMPs) and interstitial degradation of myocardium in postinfarction rats. METHODS: Seven-week old male Sprague-Dawley (SD) rats were intraperitoneally injected with isoprenaline to establish myocardial infarction (MI) model. Forty-eight rats showed clear ECG evidence of infarction and were assigned randomly to IGF-I group (rhIGF-I 50 μg·kg-1·d-1, i.v.), Oct group (Octreotide 50 μg·kg-1·d-1, i.v.) or MI group (normal sodium 5 mL·kg-1·d-1, i.v.). Each group was divided into two subgroups (n=8, respectively) according to the treatment days, 2 or 14 days when the rats were sacrificed. Another 8 normal SD rats were selected as the control group. Transthoracic echocardiograms were performed to examine the thickness of anterior wall (LVAW) and posterior wall (LVPW) of left ventricle, left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), and fractional shortening (FS) as well. The levels of MMP-2, MMP-9, TIMP-1 in myocardium were quantified with immunohistochemistry. Tissue homogenate myocardium hydroxyproline concentration was determined by pepsis method.RESULTS: Compared with the MI group, the expressions of MMP-2 and MMP-9 in rhIGF-I group were decreased, and the expression of TIMP-1 in the infarcted areas was increased;the degradation of myocardium collagen were decreased and the LVEDD and LVESD were decreased, the FS was increased; the expressions of MMP-2 and MMP-9 in Oct group were increased, the degradation of myocardium collagen was aggravated, the LVAW was decreased, the LVEDD, LVESD were increased, the FS was decreased.CONCLUSION: rhIGF-I administered to rats after MI is associated with decreased activities of MMPs, substantial increase of expression of TIMP-1, and leads to attenuate interstitial degradation of myocardium and may improve ventricular remodeling.

    AIM: To observe the effects of intravenous and intracerebroventricular injection of endomorphin-1(EM-1) on the left ventricular function in anesthetized rats and to assess its mechanism. METHODS: The left ventricular function was observed by inserting a catheter from right carotid artery into left ventricle after iv or civ injection of EM-1 in anesthetized rats.The effects of iv or civ of various blockers, naloxone, cyprodime and atropine, on the left ventricular function caused by EM-1 were observed. The level of NO and T-NOS in serum and myocardial were measured.RESULTS: EM-1 was shown to decrease left ventricular function dose-dependently. The decrease in left ventricular function was blocked by naloxone and cyprodime. Pretreatment with iv or civ atropine attenuated the decrease response. Intravenous injection of EM-1 produce NO content and NOS activity in serum were much higher than those in control group (P<0.05). While NO content and NOS activity in myocardium were no more than those in control group. Intracerebroventricular injection of EM-1 produced NO content and NOS activity in serum and myocardium were no more than those in control group. CONCLUSION: iv or civ administration of EM-1 produces depressor on the left ventricular function in anesthetized rats, which is mediated by opioid receptor, associated with the Mcholinoceptor.

    AIM: To systematically evaluate the effects of epidural anesthesia (EA) and combined spinal epidural anesthesia (CSEA) in femoral head replacement in elderly persons using meta-analysis. METHODS: Literature was retrieved in electronic databases covering PubMed, EMbase, CNKI and WanFang Data from established dates to July, 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed using the software RevMan 5.2.RESULTS: Eighteen published randomized controlled trials involving a total of 1653 patients were suitable for inclusion in the review. The results of meta-analysis revealed that, the onset, duration time of motor-block time, and the sensory regressive time of CSEA were significantly shorter in femoral head replacement than that of EA. As the duration of anesthesia of CSEA was longer than that of EA, the number of patients needed extra anesthesia of CSEA was less. Moreover, the incidence rate of hypotension, bradycardia, shivering and an episode of oxygen desaturation in femoral head replacement with CSEA was lower than that with EA. CONCLUSION: The current evidence shows that, compared with EA, CSEA in elderly is superior in anesthetic efficacy, and is good at femoral head replacement.

    AIM: To determine the influence of remifentanil on effect site concentration of propofol for loss of consciousness. METHODS: Patients scheduled for general anesthesia were randomly enrolled into group RP and group P. Group RP received target controlled infusion of remifentanil until an effect site concentration of 4 ng/mL was achieved. Then propofol was infused with a target plasma concentration of 4 μg/mL. Group P received infusion of propofol of the same target concentration. The effect site concentration of propofol for the patient losing consciousness was recorded.RESULTS: For the group RP, the ECe50 of propofol effect site concentration for patients losing consciousness was 0.84(0.75,0.93) μg/mL,while the ECe95 value was 1.40(1.27,1.59) μg/mL. However, for the group P, the ECe50 value was 1.9(1.83,1.98) μg/mL and the ECe95 value was 2.8(2.72,2.94) μg/mL. There were significant differences between the two groups considering both the two values (both P<0.05). Time to LOC and propofol needed to LOC was significantly lower in the RP group, while Narcotrend index was higher. Furthermore, the decrease of MAP was more significant in the RP group (all P<0.05).CONCLUSION: Remifentanil could increase the sedative effect of propofol and decrease the effect site concentration of propofol for loss of consciousness.

    Cyclosporine (CsA), as a novel potent immunosuppressant, is widely used in organ transplantation in recent years. Due to its narrow therapeutic index and individual difference, it has been greatly concerned that how CsA can be used rationally in clinic. The bioavailability and metabolic of CsA are mainly affected by drug-metabolizing enzymes CYP3A and P-glycoprotein transporter protein (P-gp), while the individual differences of gene polymorphism of CYP3A and multi-drug resistance gene (MDR1) are the molecular mechanisms of the generation of activity difference. In addition, the combination therapy, diet and other non-genetic factors are also an important reason for the therapeutic effect of CsA. This paper reviews the pharmacogenomics research of CsA combined with non-genetic factors, in order to provide reference for clinical individualized medicine so as to ensure safety and rational use of drugs on patients.

    The problem of medication safety about herbal injections has gained more and more attention. Pharmacokinetics is not only an important way to reveal the pharmacodynamic material basis and in vivo behavior of herbal injections, but also significant to improve the quality control standards and rational clinical use. This reveal makes a simple introduction about research status of herbal injection pharmacokinetics and indicates that the attention paid to the study is still limited. In recent years, the research of in vivo process about herbal injections could be carried out as the progress of TCM pharmacokinetics. The study of quality control, safety evaluation, process optimization and clinical rational drug use of herbal injections should use the results of the in vivo research to improve and guarantee the efficacy and safety of the injections.

    Alzheimer's disease (AD) is a chronic progressing neurodegenerative disorder, and the principal neuropathological hallmark of the disease, is the extracellular β-amyloid peptide(Aβ) accumu- lation formed senile plaques, intracellular hyperphosphorylated tau formed neurofibrillary tangles, and loss of neuron with gliocyte proliferation. Recent evidence shows that endogenous cannabinoid system serve as preventive treatment for AD, based on their neuroprotective and anti-inflammatory effects. Here we summarizes several aspects of the endogenous cannabinoid protective effect of the AD, aiming at providing a new method for the treatment of AD.

    Heparanase is a glucuronic acid enzyme, it hydrolizes heparin sulfate, which is main components of cell membrane and extracellular matrix, growth factors are released to promote tumor cell invasion and metastasis. As for the antineoplastic drug targets, a series of polysaccharides, synthetic small chemical compounds and natural product compounds have been found, some of them have begin the clinical research. The crystal structures of heparanase have successfully been discovered, so it is possible to do rational drug design based on 3D protein structures. This paper introduces antineoplastic activity research advance of heparanase inhibitors in details.
