Objective To explore effects of dizocilpine (MK-801) preconditioning on excitatory amino acids and inflammatory response in rats induced by cardiac arrest-cardiopulmonary resuscitation (CACPR).Methods 18 male Sprague Dawley (SD) rats were randomly divided into three groups:control group,CA group and CA + MK-801 group.To establish rat models of CA-CPR and keep samples of serum and specimens of brain tissues for following detection.The injury of neurons was observed by HE staining and expression of N-methyl-D-aspartic acid receptor (NMDAR) in brain tissues was detected by Western blot.The concentrations of interleukin 1 beta (IL-1 β) and tumor necrosis factor (TNF)-α in serum were detected by enzyme linked immunosorbent assay (ELISA).Results Neurons in CA group were disorganized,cells shrank,nuclei pyknosis,and cytoplasmic eosinophilia,accompanied by inflammatory cell infiltration.Preconditioning with MK-801 reduced the pathological damage of neuron and degree of macrophage infiltration.The relative expression of NMDAR protein in CA group were significantly higher than that in control group (907.9 ±24.9 vs 321.6 ± 18.4,P ＜0.001).Preconditioning with MK-801 significantly decreased the expression of NMDAR in CA + MK-801 group compared with that in CA group (512.4 ± 21.1 vs 907.9 ± 24.9).The CA group showed significantly increased concentrations of IL-1 β and TNF-α than that in control group (P ＜ 0.001),and this effect was abolished by preconditioning with MK-801.CA rats treated with MK-801 showed higher concentrations of IL-1 β and TNF-α than the control group.Conclusions Cardiac arrest causes pathological injury of neurons,up-regulates expression of NMDAR and aggravates inflammatory response.These results induce the apoptosis of nerve cells.Blocking glutamate receptor with MK-801 can inhibit expression of NMDAR,decrease level of cytokines,down-regulate inflammatory reaction degree therefore to protect the brain.

Objective To compare and analyze differences in macular thickness and to discuss the correlation between macular thickness and visual field mean defect (MD) in early and moderate,late pseudoexfoliation glaucoma (PXG) patients and normal control subjects.Methods A series of cases-observation study was adopted.Thirty-three early and moderate PXG patients (33 eyes) and 24 late PXG patients (24 eyes) were collected in the First Hospital of Shijiazhuang from May 2013 to May 2018.Meanwhile,34 age,gender and diopermatched healthy subjects (34 eyes) were included as normal control group.Spectral domain optical coherence tomography (SD-OCT) was used to measure macular thickness and volume in every quadrant.The correlation between the macular thickness and visual field MD were analyzed.This study followed the Helsinki declaration and was approved by the ethics committee of the First Hospital of Shijiazhuang.Written informed consent was obtained from each subject prior to any medical examination.Results The average macular thickness in normal control group,early and moderate PXG group and late PXG group were (305 ± 15),(297 ± 15) and (287 ± 17) μm,respectively;the average macular volume were (0.94 ± 0.05),(0.91 ± 0.05) and (0.89 ± 0.05) μm3,respectively.The macular thickness and volume differences between the 3 groups were statistically significant in nasal inner macula,superior inner macula,temporal inner macula,inferior inner macula,superior outer macula,temporal outer macula,inferior outer macula quadrants (Fthickness =4.226,9.335,12.133,10.115,11.298,8.243,12.142;all at P＜0.05.Fvolume =3.812,9.152,12.774,8.889,11.284,7.937,11.652;all at P＜0.05).The macular thickness of early and moderate PXG group in superior inner macula,temporal inner macula,inferior inner macula,superior outer macula and temporal outer macula quadrants were statistically thinner than those in the normal control group (all at P＜0.05);the macular thickness of late PXG group in inferior inner macula,temporal inner macula,superior outer macula and inferior outer macula quadrants were statistically thinner than those in the early and moderate PXG group (all at P＜0.05);the macular thickness of late PXG group in inner and outer rings were statistically thinner than those in the normal control group (all at P＜0.05).The macular thickness was not correlated with visual field MD in normal control group and the early and moderate PXG group in every quadrants (all at P＞0.05),but it was positively correlated with visual field MD in the late PXG group in nasal inner macula,superior outer macula and temporal inner macula quadrants (r =0.527,0.544,0.417;all at P＜0.05).Conclusions SD-0CT can quantify the macular thickness,and can be used an important reference index for the staging and follow-up of PXG combined with perimetry.

Objective:To provide useful information for in-depth understanding of the epidemic and molecular evolution of Coxsackievirus A4 (CV-A4), the genetic characteristics of the complete genome and recombination events in some genome regions of CV-A4 strain isolated from a patient with severe hand, foot and mouth disease (HFMD) in Yunnan province were analyzed.Methods:The CV-A4 strain was isolated from feces using RD, KMB17 and A549 cells respectively, and the viral RNA was extracted from the supernatant with CPE. The whole VP1 and complete genome sequences of the virus were amplified by RT-PCR and sequenced through Sanger’s sequencing. Complete genome sequence and genome regions of the isolated virus were analyzed through MEGA7.0 and SimPlot 3.5.1 software.Results:The virus isolated from RD cells belonged to CV-A4 and was designated as R11-20/YN/CHN/2011 strain. This CV-A4 strain was C2 sub-genotype through phylogenetic analysis based on the VP1 sequence. CV-A4 R11-20/YN/CHN/2011 has the highest nucleotide sequence identity with 09214/SD/CHN/2009 in VP1 and CVA4/SZ/CHN/09 in the complete genome. Recombination occurred between CV-A4 R11-20/YN/CHN/2011 and EV-A71 in 3D region.Conclusions:The CV-A4 R11-20/YN/CHN/2011 strain belongs to C2 sub-genotype and recombines with EV-A71 in 3D region.

ObjectiveTo observe the clinical effectiveness of point ligation therapy combined with catgut embedment in acupoint for patients with refractory facial paralysis， and to explore the possible mechanisms from the perspective of neurotrophic factors. MethodsTotally 168 patients with intractable facial paralysis were randomly divided into point ligation plus catgut embedment group and electroacupuncture group， with 84 cases in each group. Both groups took methylcobalamin tablets orally， on the basis of which the point ligation plus catgut embedment group gave point ligation therapy at Quanliao （SI 18）， Dicang （ST 4）， Jiache （ST 6）， and catgut embedment in the local acupoints on the affected side combined with the distal acupoints， and the point ligation therapy combined with catgut embedment in acupoint was performed once every 30 days for three treatments； the electroacupuncture group took the same acupoints and gave electroacupuncture， with sparse and dense waves， once every other day. Both groups were treated for 90 days. Before treatment and after 30， 60， 90 and 120 days （follow-up）， patients of both groups were observed for House-Brackmann Facial Nerve Grading （HB） and modified Portmann score； facial nerve electromyography was performed before treatment and after 90 days of treatment to record the wave amplitude and latency of facial nerve motor conduction， and serum brain-derived nerve growth factor （BDNF）， nerve growth factor （NGF）， fibroblast growth factor （FGF2） levels were determined. The clinical effectiveness of both groups after 90 days of treatment was compared， and the adverse events occurred in the course of treatment in all patients were recorded. ResultsAt 30 days， 60 days， 90 days and follow-up visits， the HB grading of patients in both groups improved compared with that before treatment （P＜0.05）； the distribution of the number of patients with HB grading in the point ligation plus catgut embedment group was superior to that in the electroacupuncture group after 60 days and 90 days of treatment and at follow-up visits （P＜0.05）. The maximal amplitude of the facial nerve electromyography in both groups after 90 days of treatment was large， and the latency was shorter when compared with those before treatment （P＜0.05）， and the maximum wave amplitude of the point ligation plus catgut embedment group was higher than that of the electro-acupuncture group， and the latency period was shorter than that of the electro-acupuncture group （P＜0.05）. The modified Portmann scores of the both groups of patients after 30， 60 and 90 days of treatment and follow-up were higher than those before treatment， and the scores of the point ligation plus catgut embedment group were higher than those of the electroacupuncture group （P＜0.05）. Serum BDNF， NGF and FGF2 levels in both groups after 90 days of treatment were higher than before， and the point ligation plus catgut embedment group was significantly higher than the electroacupuncture group （P＜0.05）. The total clinical effective rate of the point ligation plus catgut embedment group （92.68%） was higher than that of the electroacupuncture group （81.01%， P＜0.05）. Adverse reactions occurred in both groups， mainly including local haematoma or subcutaneous bleeding， allergic reaction， severe pain， and needle fainting， all of which disappeared after symptomatic treatment. ConclusionThe point ligation therapy combined with catgut embedment in acupoint for patients with refractory facial paralysis are effective. The therapy improve the facial nerve function， and its mechanism of action may be related to increasing the level of serum neurotrophic factor and thus promoting facial nerve repairment.
