ObjectiveTo explore the effect of system reading therapy on alexia after stroke.Methods104 stroke patients with alexia were divided into two groups: observation group(51) and control group(53). General speech training were used for the two groups, while the observation group received system reading training at the same time, all for 30 minutes, once a day for 1 month. Chineses Standard Aphasic Examination was applied to assess the reading ability before and 1 month after treatment.ResultsThere are three kinds of alexia in the patients: frontal alexia, alexia with agaphia, and subcortical aphasic alexia. Reading ability improved in the two groups (P<0-01), but the observation group was better than the control group(P<0-05).ConclusionSystem reading therapy is very helpful to improve reading ability of stroke patients with alexia.

0.99).The limits of detection were below 0.5 ?g/L.The rates of recovery for the spiked samples ranged from 70.1% to 117.9% and the relative standard deviations(RSD) were between 0.4%-16.1%.Conclusion The method is simple,rapid,accurate and is applicable to the simultaneous determination of multi-pesticide residues in drinking water.

Traditional Chinese medicine (TCM)has certain advantages in the treatment of chronic liver diseases,especially chronic inflam-matory injury and liver fibrosis.However,the studies on medicinal components and action mechanism of TCM prescriptions are confronted with a great challenge.The computational pharmacology methods used in recent years,mainly including virtual screening technique,omics technologies,and network pharmacology approaches,as well as their application in TCM research,are presented;given the previous re-search work,the progress in research on active ingredients and action mechanism of TCM prescriptions using computational pharmacology methods is reviewed.It is thought that computational pharmacology techniques combined with conventional molecular biological and pharma-cological methods are an important research strategy for the material basis and action mechanism of TCMprescriptions for treating chronic liv-er diseases.

Objective To study the imaging features of MRI in children glioblastoma and improve the understanding of this disease.Methods The clinical data and MR features of 5 cases in children with glioblastoma confirmed by surgery and pathology were analyzed retrospectively. Imaging features including location,shape,growth pattern,peritumoral edema and contrast enhancement were assessed.Results 4 cases occurred in the cerebral hemisphere and 1 in cerebellar hemisphere,all of which manifested obvious mass effect with 2 cases across midline.3 cases were round-like,while another 2 cases were irregular in shape.In spite of 1 case without peritumoral edema, 4 cases performed mild to moderate peritumoral edema.Among all patients,one showed cystic mass,2 caese showed cystic-solid mass,and the other 2 cases showed solid mass.Cystic portion presented long T1 and long T2 signal,as well as low signal on FLAIR. Solid part of lesion showed iso-intense on T1 WI and T2 WI,as well as high signal on FLAIR and DWI.After contrast enhancement,cyst wall showed annular enhancement.Ring-shaped or nodular enhancement was seen in solid components of cystic-solid mass.And solid mass showed irregular and lump-like enhancement.Conclusion Glioblastoma in children has certain characteristic MRI appearances. The surgical and pathological results are still required to establish the final diagnosis.

Objective To investigate the levels of IL-18,IL-10 and MMP-9 in coronary heart disease(CAD)patients with in-stent restenosis(ISR)after percutaneous coronary intervention (PCI)treatment,so as to discuss the influence of inflammatory fac-tors to ISR after PCI.Methods CAD patients with ISR after PCI were angiographically re-evaluated and formed the ISR group(n=68)and the non-ISR group(n=173)based on the presence or absence of ISR.109 subjects without angiographic evidence of CAD formed a reference control group(control group).The plasma IL-18,IL-10 and MMP-9 concentrations of subjects were measured. Results The concentrations of serum IL-18 and MMP-9 in ISR group and non-ISR group were significantly higher than control group,while IL-10 level was the opposite.Contrasted with non-ISR group,the concentrations of serum IL-18 and MMP-9 in ISR group were significantly higher,but IL-10 level was the opposite too.There were significantly statistical differences(P <0.05)Con-clusion There is significant correlation between ISR and serum levels of IL-18,IL-10 and MMP-9.The inflammation may have im-portant impact on the process of ISR.

Objective:To investigate the effect of different ventilation time in the prone position on patients with endogenous/exogenous ARDS.Methods:30 endogenous/30 exogenous ARDS patients were randomly devided into 4 groups,ventilation in the prone position for 2 h and 4 h.Recording the score of APCHEII,oxygenation index,the absorption situation in X-ray,HR,MAP,extubation time,the time out of ICU.Results:The APCHEII scores HR and MAP in four groups have no significant statistics (P＞0.05);4h ventilation for endogenous ARDS patients has a better indicators than 2 h in oxygenation index,the absorption situation in X-ray,extubation time and the time out of ICU (P＜0.05);2 h and 4 h ventilation for exogenous ARDS patients can improve indicators above,two groups have no significant statistics (P＞0.05),the results of exogenous groups are precede than endogenous group (P＜0.05).Conclusion:Ventilation in the prone position can improve the situation of ARDS patients,both endogenous patients and exogenous patients.Exogenous ARDS patients have a better treatment effect after the ventilation of 2h,however,endogenous patients need longer time and have a non-ideal prognosis.

Objective: To study the chemical constituents of volatile oil from flower of Dendrobium candidum Wall. ex Lind1. Methods: The chemical compositions of volatile oil of the plant which were obtained by steam distillation with hexane were analyzed by GC-MS equipped with a elastic quartz capillary column-HP-5MS5% Phenyl Methyl Siloxane (30 m? 0.25 mm ?0.25 ?m). The constituents were identifi ed by their mass spectra. The relative percentage of the oil constituents was calculated from the GC peak areas. Results: Eighty-nine kinds of chemical constituents in Dendrobium candidum Wall.ex Lind1.flower were separated; of which fifty-nine compounds representing 76.51% of the oil were characterized. Relative contents that were more than 2.0% were determined as Nonanal 9.21%, Eudesma-5,11-dien-8,12-olide 5.55%, (E)-2-Decenal 4.63%, 2,3-Dehydro- 1,8-cineole 4.39%, Pentacosane 4.03%,?-Cedrol 3.69%, Isoalantolactone 3.65%, (E)-2-Heptenal 3.60%, E,E-2,4-Decadienal 2.14%,?-Phorone 2.03%.Conclusion: This paper reports, for the first time, the composition of volatile oils of Dendrobium candidum Wall.ex Lind1.flower by GC/MS.

Objective To assess the effect of repetitive transcranial magnetic stimulation (rTMS) at different frequencies on behavioral and psychological symptoms and cognitive function in patients with Alzheimer's disease.Methods Seventy-two patients were randomly divided into a high frequency group,a low frequency group and a control group (n =24 for each),and given 10 Hz,1 Hz or sham rTMS over the left and right dorsolateral prefrontal cortex at an intensity was 80％ of each patient's movement threshold.The stimulation was for 30 min a day,five days a week.During the 4 weeks of treatment,risperidone was used at a fixed dose of 1 mg per day for all patients.Before and after the treatment,all 3 groups were assessed using the behavioral pathology in Alzheimer's disease rating scale (BEHAVE-AD) and the mini-mental state examination (MMSE).Results Two weeks after the treatment,the average BEHAVE-AD score of the high frequency group had decreased significantly from (16.75±6.26) to (13.84± 6.10),significantly lower than the low frequency and the control groups' averages.Two weeks later,the average BEHAVE-AD scores of the 3 groups were significantly lower than before the treatment,but the decrease of the high frequency group was of significantly greater compared to the other 2 groups.Four weeks after the treatment the average MMSE score of the high frequency group was significantly better than before the treatment (P＜0.01),and better than the low frequency and the control group's averages.The effectiveness rates of the high frequency group,the low frequency group and the control group were 88％,58％ and 54％ respectively,all significantly different.Conclusion High frequency (10 Hz) rTMS combined with risperidone can improve the behavioral and psychological symptoms and cognitive function of AD patients,while low frequency (1Hz) rTMS does not have obvious effects.
