Spinal cord injury is a serious trauma of the spinal and nervous system, local tissue destruction and microcirculation disturbance can lead to a more serious spinal cord injury and extensive necrosis of neurons. Spinal cord injury often accompany with Inflammation reaction producing a variety of cytokines and bioactive substances, result in macrophage polarization. M1 macrophages polarization are induced by IFN-γ, LPS, TNF-α and so on, it show the damage and proinflammatory effect. M2 macrophages polarization are caused by IL-4, IL-10, IL-13 and show the recovery and anti-inflammatory effect. However, clinical treatment after spinal cord injury is very limited, inhibition of proinflammatory and promotion of anti-inflammatory by regulating the M1 macrophages and M2 macrophages is a new direction for the treatment of spinal cord injury. The article will review different phenotype and function of macrophages after spinal cord injury.

OBJECTIVETo evaluate anti-melanoma effect of ethanol extract of Ilex hainanensis Merr. (IME) and elucidate its underlying mechanism.
METHODSThirty-six tumor-bearing mice were randomized into 6 groups (n=6) as follows: model group, IME 25, 50, 100, and 200 mg/kg groups and dacarbazine (DTIC) 70 mg/kg group. The mice in the IME treatment groups were intragastrically administered with IME 25, 50, 100 or 200 mg/kg per day, respectively. The mice in the DTIC group were intraperitoneally injected with DTIC 70 mg/kg every 2 days. The drug administration was lasting for 14 days. The cell viability was evaluated by 3-(4,5-dime-thylthylthiazol-2-yl)-2, 5-diphenyl-tetrazolium bromide (MTT) assay. Flow cytometry was employed to detect cell cycle and apoptosis. The gene and protein expressions of nuclear factor κB-p65 (NF-κB-p65), Bcl-2, B-cell lymphomaextra large (Bcl-xL) and Bax were detected by quantitative real-time polymerase chain reaction and Western blot analyses. Caspases-3, -8, and -9 activities were detected using the colorimetric method. In addition, a B16-F10 melanoma xenograft mouse model was used to evaluate the anti-cancer activity of IME in vivo. Furthermore, a survival experiment of tumor-bearing mice was also performed to evaluate the possible toxicity of IME.
RESULTSIME significantly inhibited the proliferation of B16-F10 cells (P<0.01). Flow cytometric analysis showed that IME induced G/S cell cycle arrest and apoptosis (both P<0.01). IME inhibited activation of NF-κB, decreased the gene and protein expressions of Bcl-2, Bcl-xL, and increased the gene and protein expressions of Bax (all P<0.01). In addition, IME induced the activation of Caspases-3, -8, and -9 in B16-F10 cells. The study in vivo showed that IME significantly reduced tumor volume (P<0.01), and the inhibitory rate came up to 68.62%. IME also induced large areas of necrosis and intra-tumoral apoptosis that correlated with a reduction in tumor volume. Survival experiment showed that treatment with IME for 14 days significantly prolonged survival time and 20% of mice in the IME 200 mg/kg group were still alive until the 50th day. Notably, IME showed no apparent side-effects during the treatment period.
CONCLUSIONIME exhibited significant anti-melanoma activity in vitro and in vivo, suggesting that IME might be a promising effective candidate with lower toxic for malignant melanoma therapy.

BackgroundHigh platelet reactivity (HPR) during clopidogrel treatment predicts postpercutaneous coronary intervention (PCI) ischemic events strongly and independently. Tongxinluo capsules (TCs) are a traditional Chinese medicine formulation used as antiplatelet treatment. However, its efficacy against HPR is not known. The aim of the present study was to evaluate the effects of TCs in acute coronary syndrome (ACS) patients with HPR.
MethodsThis multicenter, randomized, double-blind, placebo-controlled study prospectively analyzed 136 ACS patients with HPR who underwent PCI. The patients were enrolled from November 2013 to May 2014 and randomized to receive placebo or TCs in addition to standard dual antiplatelet therapy (DAPT) with aspirin and clopidogrel. The primary end points were the prevalence of HPR at 30 days and the mean change in P2Yreaction units (PRUs) between baseline and 30 days. Survival curves were constructed with Kaplan-Meier estimates and compared by log-rank tests between the two groups.
ResultsBoth groups had a significantly reduced prevalence of HPR at 30 days versus baseline, but the TC group, compared with the placebo group, had greater reduction (15.8% vs. 24.8%, P = 0.013), especially among patients with one cytochrome P450 2C19 loss of function (LOF) allele (χ= 2.931, P = 0.047). The TC group also had a lower prevalence of HPR (33.3% vs. 54.2%, t = 5.284, P = 0.022) and superior performance in light transmittance aggregometry and higher levels of high-sensitivity C-reactive protein (hsCRP), but the composite prevalence of ischemic events did not differ significantly (χ= 1.587, P = 0.208).
ConclusionsIn addition to standard DAPT with aspirin and clopidogrel, TCs further reduce PRU and hsCRP levels, especially in patients carrying only one LOF allele. The data suggest that TCs could be used in combination therapy for ACS patients with HPR undergoing PCI.

PURPOSE: Urapidil is putatively effective for patients with hypertension and acute heart failure, although randomized controlled trials thereon are lacking. We investigated the efficacy and safety of intravenous urapidil relative to that of nitroglycerin in older patients with hypertension and heart failure in a randomized controlled trial. MATERIALS AND METHODS: Patients (>60 y) with hypertension and heart failure were randomly assigned to receive intravenous urapidil (n=89) or nitroglycerin (n=91) for 7 days. Hemodynamic parameters, cardiac function, and safety outcomes were compared. RESULTS: Patients in the urapidil group had significantly lower mean systolic blood pressure (110.1±6.5 mm Hg) than those given nitroglycerin (126.4±8.1 mm Hg, p=0.022), without changes in heart rate. Urapidil was associated with improved cardiac function as reflected by lower N terminal-pro B type natriuretic peptide after 7 days (3311.4±546.1 ng/mL vs. 4879.1±325.7 ng/mL, p=0.027) and improved left ventricular ejection fraction (62.2±3.4% vs. 51.0±2.4%, p=0.032). Patients given urapidil had fewer associated adverse events, specifically headache (p=0.025) and tachycardia (p=0.004). The one-month rehospitalization and all-cause mortality rates were similar. CONCLUSION: Intravenous administration of urapidil, compared with nitroglycerin, was associated with better control of blood pressure and preserved cardiac function, as well as fewer adverse events, for elderly patients with hypertension and acute heart failure.

We have carried out the chemical investigation on the roots of Alangium chinense. The chemical constituents from the roots of A.chinense were isolated and purified by various chromatographic techniques, such as silica gel, MCI-Gel resin, Sephadex LH-20 and high performance liquid chromatography. As a result, three alkaloids (1-3) were isolated from 90% EtOH extracts of the roots of this plant. Their structures were elucidated by physical-chemical properties and spectral data. Among them, compound 1 is a new compound, determined as 8-hydroxy-3-hydroxymethyl-6,9-dimethyl-7H-benzo[de]isoquinolin-7-one. Cytotoxicity of the compounds was evaluated by the MTT method. Compound 1 displayed cytotoxicity against NB4, A-549, SHSY5Y, PC-3 and MCF-7 cell lines with IC₅₀ values of 4.2, 3.5, 5.7, 2.8 and 3.9 μmol•L⁻¹, respectively.

Human diphyllobothriasis is a parasitic disease caused by ingestion of larvae (plerocercoids) in raw or undercooked fish and commonly found in temperate areas. Rare cases were reported in tropical or subtropical areas especially in children. The first documented case of pediatric diphyllobothriasis in Taiwan had been reported 11 years ago. Here, we report another 8-year-old girl case who presented with a live noodle-like worm hanging down from her anus, with no other detectable symptoms. We pulled the worm out and found the strobila being 260 cm in length. Examination of gravid proglottids showed that they were wider than their lengths, containing an ovoid cirrus sac in the anterior side and the rosette-shaped uterus. Eggs extracted from the uterus were ovoid and operculated. Diphyllobothrium latum was confirmed by molecular analysis of the mitochondrial DNA cytochrome c oxidase subunit 1 (cox1) gene. The girl was treated with a single oral dose of praziquantel, and no eggs or proglottids were observed from her stool in the subsequent 3 months. The reemergence of human diphyllobothriasis in non-endemic countries is probably due to prevalent habit of eating imported raw fish from endemic areas. This pediatric case raised our concern that human diphyllobothriasis is likely underestimated because of unremarkable symptoms.

OBJECTIVETo investigate the efficacy of 2-month course of sleeping position correction in the treatment of positional plagiocephaly in infants aged <8 months.
METHODSA total of 73 infants with positional plagiocephaly between January 2015 and June 2016 were divided into treatment group (n=46) and control group (n=27) according to parents' wishes. The treatment group received sleeping position correction, while the control group received sleep curve mattress. The oblique diameters A and B in the two groups were measured and the cranial vault asymmetry (CVA) was calculated before and after treatment. The severity of positional plagiocephaly based on CVA was compared between the two groups before and after treatment. The Gesell Developmental Scale was used to determine the developmental quotients (DQs) in the motor, adaptive, language, and social domains in the two groups before and after treatment.
RESULTSBefore treatment, there were no significant differences in oblique diameters A and B, CVA, and DQs in the four specific domains between the two groups (P>0.05). After 2 months of treatment, the treatment group had a significantly greater oblique diameter B and a significantly smaller CVA than the control group (P<0.05); there were no significant differences in DQs in the four specific domains between the two groups (P>0.05). After treatment, both groups had significant improvements in oblique diameters A and B, CVA, and DQs in the motor and adaptive domains (P<0.01); moreover, the treatment group showed a significant improvement in the DQs in the social domain (P<0.01). There was no significant difference in the severity of positional plagiocephaly between the two groups before and after treatment (P>0.05).
CONCLUSIONSFor infants with positional plagiocephaly, sleeping position correction has better efficacy and is more convenient and economical than the sleep curve mattress, so it holds promise for clinical application.

OBJECTIVETo investigate the influence of home nurture environment on language development and social emotion in children with developmental language disorder (DLD).
METHODSThe 1-3 Years Child Home Nurture Environment Scale, Gesell Developmental Scale, and Infant-Toddler Social and Emotional Assessment Scale were used for the evaluation of 125 children with DLD. A total of 130 children with normal language development matched for age and sex were enrolled as control group.
RESULTSCompared with the control group, the DLD group had a significantly higher proportion of children in a bad home nurture environment and significantly lower scores of all domains of home nurture environment (P<0.05). In children with DLD, the home nurture environment score was positively correlated with the level of language development (r=0.536, P<0.01) and the score of ability domain in social emotion (r=0.397, P<0.01) and was negatively correlated with the scores of the domains of explicit behavior, covert behavior, and imbalance in social emotion (r=-0.455, -0.438, and -0.390 respectively, P<0.01). Home nurture environment had direct influence on language development in children with DLD and affected their language development via the mediating effect of social emotion.
CONCLUSIONSHome nurture environment influences language development and social emotion in children with DLD, and social emotion has a partial mediating effect between home nurture environment and language development.
