Neuromyelitis optica (NMO)/NMO spectrum disorder (NMOSD) is a chronic, recurrent, antibody-mediated, inflammatory demyelinating disease of the central nervous system, characterized by optic neuritis and transverse myelitis. The binding of NMO-IgG with astrocytic aquaporin-4 (AQP4) functions directly in the pathogenesis of >60% of NMOSD patients, and causes astrocyte loss, secondary inflammatory infiltration, demyelination, and neuron death, potentially leading to paralysis and blindness. Current treatment options, including immunosuppressive agents, plasma exchange, and B-cell depletion, are based on small retrospective case series and open-label studies. It is noteworthy that monoclonal antibody (mAb) therapy is a better option for autoimmune diseases due to its high efficacy and tolerability. Although the pathophysiological mechanisms of NMOSD remain unknown, increasingly, therapeutic studies have focused on mAbs, which target B cell depletion, complement and inflammation cascade inactivation, blood-brain-barrier protection, and blockade of NMO-IgG-AQP4 binding. Here, we review the targets, characteristics, mechanisms of action, development, and potential efficacy of mAb trials in NMOSD, including preclinical and experimental investigations.

OBJECTIVE:To observe the clinical effect and safety of recombinant human brain natriuretic peptide (rhBNP) combined with levosimendan in the treatment of acute decompensated heart failure (ADHF)complicated with renal insufficiency. METHODS:A total of 156 patients with ADHF complicated with renal insufficiency admitted to the Dept. of Cardiology in the Affiliated Hospital of Southwest Medical University during Jan.-Dec. 2019 were randomly divided into rhBNP group ,levosimendan group and combination group ,with 52 patients in each group. All patients received rountine treatment. On this basis ,rhBNP group was given rhBNP for injection [after 1.5 μg/kg intravenous pulse injection,intravenous dripping for 24 h with 0.007 5 μg(/ kg· min)];leosimendan group was given Leosimendan injection 12.5 mg [intravenous dripping for 1 h with 6-12 μg(/ kg·min),then intravenous dripping for 23 h with 0.1 μg(/ kg·min)]. Combination group received drug combination according to the administration method of single drug group. Three groups received treatment for consecutive 7 d. Cardiac function indexes [heart rate (HR),left ventricular ejection fraction (LVEF),left ventricular end-diastolic diameter (LVEDD)],mean arterial pressure (MAP),pulmonary capillary pressure (PCWP),renal function indexes [estimated glomerular filtration rate (eGFR),serum creatinine (Scr)],serum levels of cystatin C (Cys-c)and amino-terminal brain natriuretic peptide precursor (NT-proBNP)were observed in 3 groups before and after treatment. Clinical efficacy and the occurrence of ADR were recorded. RESULTS :Three cases withdrew from the study in rhBNP group and 1 case in levosimendan group ;152 cases completed the study. Before treatment ,there was no statistical significance in cardiac function indexes ,MAP,PCMP,renal function indexes or serum levels of Cys-C and NT-proBNP among 3 groups(P>0.05). After treatment ,the HP ,MAP,PCWP and serum level of NT-proBNP in 3 group as well as serum level of Cys-C in combination group were decreased significantly (P<0.05);the LVEF in 3 group as well as the eGFR and Scr level in levosimendan group and combination group were significantly increased (P<0.05),compared with before treatment ;above indexes of combination group were significantly better than those of rhBNP group and levosimendan group (P<0.05). Total effective rate of combination group was 94.23% ,which was significantly higher than those of rhBNP group (77.55%)and levosimendan group (76.47%)(P<0.05). There was no significant difference in the incidence of ADR among 3 groups(P> 0.05). CONCLUSIONS :rhBNP combined with levosimendan in the treatment of ADHF complicated with renal insufficiency can significantly increase the clinical efficacy ,and improve cardiac and renal function but don ’t increase the incidence of ADR.

OBJECTIVE: To observe the effects of nicorandil on vascular endothelial function and angina pectoris recurrence in patients with unstable angina pectoris after percutaneous coronary intervention (PCI). METHODS: Totally 195 patients with unstable angina pectoris were collected from Sichuan Provincial People’s Hospital during Jan. 2016-Mar. 2018, and then divided into control group (97 cases) and observation group (98 cases) according to random number table. Both groups received PCI, and then given basic treatment as Enoxaparin sodium injection, Isosorbide mononitrate sustained-release tablets, Aspirin enteric-coated tablets, Clopidogrel sulfate tablets and Atorvastatin calcium tablets after PCI. Observation group additional received Nicorandil tablet 5 mg, tid, on the basis of control group. Both groups were treated for 6 months. The levels of vascular endothelial function related indexes (FMD, ET-1, NO), myocardial injury markers (cTnⅠ, CK-MB) and inflammatory factors (hs-CRP) were observed before and after PCI. The recurrent angina pectoris, the occurrence of MACE and ADR were recorded. RESULTS: 6 patients of control group and 4 patients of observation group withdrew from the study. One day before operation, there was no significant difference in the levels of vascular endothelial function, myocardial injury markers or inflammatory factors between 2 groups (P>0.05). One day after operation, the levels of FMD and NO in both groups decreased significantly, while the levels of ET-1, cTnⅠ and CK-MB increased significantly (P<0.05). The levels of FMD and NO were increased significantly in the 1st and 6th months after surgery, and the observation group was significantly higher than the control group; the levels of ET-1, cTnⅠ, CK-MB and hs-CRP were decreased significantly, and the observation group was significantly lower than the control group (P<0.05). The incidence and times of recurrent angina pectoris, duration, the proportion of grade Ⅲ angina pectoris and total incidence of MACE in observation group were significantly lower, less or shorter than control group (P<0.05). There was no statistical significance in total incidence of ADR between 2 groups (P>0.05). CONCLUSIONS: Additional use of nicorandil can improve vascular endothelial function, relieve the myocardial injury and inflammatory response, reduce the occurrence of recurrent angina pectoris and MACE after PCI and doesn’t influence the safety of routine treatment.

Objective To investigate the effect of sertraline on the viability and the expression of tyrosine hydroxylase (TH) and phosphorylated ERK1/2 in NGF-induced rat pheochromocytoma (PC12) cells.Methods NGF-induced PC12 cells were pretreated or directly treated with different concentrations of sertraline for 24 or 48 hours and the pretreated groups were then subjected to serum withdrawal condition. Then cell viability was determined by the cell counting Kit-8 (CCK-8). The expression of Tyrosine hydroxylase (TH) and pERK1/2in NGF-induced PC12 cells was determined by immunohistochemistry and western blot respectively. Results The viability of NGF-induced PC12 was improved after administration with sertra]ine. After 24h sertraline administration, the cells activity of PC 12 cells at 20μM ( 1.32 ± 0. 11 ) , 10μM ( 1. 17 ± 0.05 ) of direct effect, and 20μM ( 1.15 ±0.11 ) of protect effect increased dramatically as compared with control group. But high dose ( 50μM )sertraline express high toxic effect to PC12 cells. The expression of TH was increased by sertraline 20 μM at both 24h(ratio of TH/β-actin = 1.27 ±0.05) and 48h(ratio of TH/β-actin = 1. 23 ±0.08) compare with control group,and the expression of pERK1/2 also increased dramatically by sertraline 20 μM at both 24h (ratio of (pERK1/2)/β-actin = 1.41±0.05) and 48h( ratio of (pERK1/2)/β-actin = 1.40 ±0.06) compare with control group(P<0. 01, P < 0. 05). Immunohistochemistry showed similar results. Conclusion These data suggest that the neuroprotective effect of sertraline may play an important role in depression therapy, and this effect might be mediated by TH and pERK1/2 up-regulation.
Résumé
To identify metabotropic glutamate receptor 4 (mGluR4) modulators by Ca2+ influx assay, we developed the functional cell-based high throughput-screening (HTS) assay. The human mGluR4 cDNA was transfected into HEK-293 stably expressing promiscuous G-protein (Ga alpha15) cells. Recombinant stable mGluR4 cell line was selected under Zeocin and validated by Ca2+ influx assay. The assay was optimized on loading time of Fluo Calcium Indicator, Dimethyl sulfoxide (DMSO) tolerance and sodium hydroxide (NaOH) tolerance using agonist (L-Glutamic acid (L-Glu)) of mGluR4. The rank order of the agonist potency for the stable human mGluR4 cell line was L-(+)-2-Amino-4-phosphonobutyric acid (L-AP4) > L-Serine-O-phosphate (L-SOP) > L-Glu, and of the antagonist potency was (RS)-alpha-Methylserine-O-phosphate (MSOP) > (RS)-alpha-Methyl-4-phosphonophenylglycine (MPPG). Z' factor value of the cell line in 96- and 384-well plate format was 0.80 and 0.65. Our data indicate a successful development of functional human mGluR4 recombinant stable cell line that was suitable for high throughput screening to identify mGluR4 agonist/antagonist.
