Objective To explore the effect of inhibitor of MEK/ERK pathway on the behaviors of autistic rats .Methods Autistic rats were made by intraperitoneal injection of sodium valproate (VPA) after pregnancy for 12 .5 days .After VPA injec-tion ,pregnant rats were treated with U0126 via oral at 400 μg/kg dose per day until weaning .Young rats were divided to 4 groups :control group ,VPA group ,U0126 group ,VPA combined U0126 group .The social interaction and behaviors of young rats were e-valuated at 35 days after bornning .The levels of MEK and phosphorylated ERK in brain tissues were investigated by Western blot . Results The autistic rat mode was prepared successfully .Compared with control rats ,the rats treated with VPA showed low the social interaction ,long moving time in central area and reducing standing times .Treatment with U0126 alone didn′t change the so-cial interaction and behaviors of young rats ,but VPA combined U0126 group could improve VPA-induced autistic-like behaviors . Western blot results show that compared with the control group ,the rats treated with VPA could enhance the prefrontal cortex of rats ,the hippocampus and cerebellum in the organization of MEK and ERK phosphorylation level ;while VPA combined U0126 group could inhibit the brain tissue of MEK and ERK phosphorylation level .Conclusion U0126 can improve the model rats of au-tism disorders behavior ,the mechanism may be related to the inhibition of MEK/ERK signaling pathway in the brain .

Objective To analyze the magnetic resonance imaging(MRI)features of multiple sclerosis(MS)patients both in the brain and the spinal cord and to explore its relationship with factors such as quality of life,disability of MS patients and so on.Methods A total of 170 MS patients confirmed clinically underwent MRI examination and answered the questionnaires of Multiple Sclerosis Quality Of Life-54 instrument,Expanded Disability Status Scale,Hamilton Anxiety Scale and Hamilton Depression Scale.Results The lesions on brain MRI were usually seen in the white matter around the lateral ventricles,the centrum ovale majus and frontal lobe.The commonly seen length of the single lesions on the spinal cord was as long as that of 1-2 vertebral bodies,but that of the fused lesions was as long as that of 4-5 vertebral bodies.The distribution of the lesions was significantly correlated with the quality of life,the degrees of the disability,anxiety and depression.Conclusion MRI examination is useful for early and better diagnosis of MS and can provide guidance for treatment,and thus can improve the prognosis and the quality of life of patients.

Objective To identify endoscopic and the endoscopic ultrasonography (EUS) features of esophageal tuberculosis.Methods We retrospectively analyzed the data of 39 cases (mean age 50.7) of esophageal tuberculosis diagnosed by endoscopy and EUS in past 6 years.Results A total of 29 lesions were found in the middle part of esophagus,and 5 in upper and lower part,respectively.The lesions under endoscope demonstrated as protrusion in 30 and ulceration in 9.EUS found esophageal wall thickness in 9 cases,intra-wall occupying lesion in 17,mediastinum occupying lesions involving esophagus in 13,and calcified lymph nodes in mediastinum which was integrated with esophageal outer wall in 28 cases.Conclusion The esophageal tuberculosis occurs mainly in the middle part of the esophagus,and appears as protrusion and ulceration under endoscopy.EUS can find occupying lesions intra-or out of the esophageal wall,and full layer thickness,which can accompany calcified lymph nodes in meidastinum,and can be the basis of diagnosis.

Objective:To detect the interleukin-22(IL-22) levels in peripheral blood of the asthma patients and analyze the relationship between the IL-22 levels and IgE,pulmonary function,fractional exhaled nitric oxide(FENO),and to investigate the role of IL-22 in the pathogenesis of bronchial asthma. Methods:Seventy-eight patients with asthma were selected as experiment group.The asthma patients were divided into increased IgE group (n=46)and normal IgE group(n=32)according to the IgE levels.The asthma patients were also divided into acute attack stage and clinical control stage according to patients' clinical symptoms.In addition, twenty healthy controls were chosen as healthy control group.The plasma IL-22 levels, IgE,forced expiratory volume in one second (FEV1) and FENO levels of the subjects in various groups were detected and compared between various groups.The correlations between the plasma IL-22 levels and IgE, FEV1,FENO were analyzed.Results:The plasma IL-22 level and FENO level of the patients in asthma group were higher than those in healthy control group(P<0.05).The IL-22 level and FENO level of the patients in clinical control stage were lower than those in acute attack stage,but they were still higher than those in healthy control group(P<0.05).The plasma IL-22 level of the patients in increased IgE group was higher than that in normal IgE group(P<0.05).There were significant negative correlations between the IL-22 levels and FEV1 in the asthma patients in acute attack group and clinical control group(r=-0.365 3,P<0.05;r=-0.267 2,P<0.05),but there was no significant correlation between the IL-22 levels and FENO(r=0.011 9,P>0.05;r=0.059 8,P>0.05).Conclusion:The increased expression of IL-22 in peripheral blood of the patients with asthma may participate in the pathogenesis of asthma,and may aggravate the deterioration of pulmonary function of the asthma patients.

OBJECTIVE:To evaluate the effects of quality control circle(QCC)in improving the compliance of asthma/COPD outpatients handling inhaler devices. METHODS:By simple random sampling method,90 asthma/COPD outpatients receiving Tiotropium bromide powder for inhalantion,Salmeterol xinafoate and fluticasone propionate powder for inhalantion and Budesonide and formoterol fumarate powder for inhalantion were selected from our hospital during Apr. to Nov. 2015. The reasons for poor com-pliance of handling inhaler devices were analyzed by QCC. The countermeasures were formulated to improve the compliance,in-cluding clinical pharmacist education,follow-up,issuing education manuals,developing WeChat consulting. Operation step score of inhaler devices,compliance score and activity ability score of QCC members were analyzed statistically before and after QCC. RESULTS:After the development of QCC,operation step score of inhaler devices and compliance score in 90 asthma/COPD outpa-tients increased from 7.7 and 7.7 before activity to 8.8 and 9.3 after activity,the achievable rate of compliance was 114.3%,and the improvement rate was 20.8%. The sense of honor,responsibility,self-confidence,QCC techniques,communication and coordi-nation,team cohesion of all members were all improved obviously. CONCLUSIONS:QCC activity improves the compliance of asthma/COPD outpatients handling inhaler devices and shows the professional service level of clinical pharmacists,which is of sig-nificance to the improvement of pharmaceutical care.

Objective To investigate the prevalence,characteristics and risk factors of fatigue in a large cohort of subjects with early Parkinson's disease (PD).Methods A total of 391 individuals with PD,recruited in Linzhi trial,were re-screened.Early,non-depressed subjects [Center for epidcmiological survey depression scale (CES-D)＜16]underwent further fatigue assessment.Subjects who scored＞4 on fatigue severity scale (FSS) were classified as fatigue.Motor symptoms and PD severity were assessed using the unified Parkinson's disease rating scale (UPDRS) and Hoehn-Yahr scale.Other clinical measures,including sleep disorder by Pittsburg sleep quality index (PSQ-Ⅰ),mental function by Alzheimer's Disease assessment scale-cognitive sections (ADAS-Cog) and quality of life by medical outcomes study short form 36 (SF- 36) were also evaluated.Results Among 204 subjects who completed fatigue measures,82 (40.2％) were classified as fatigue.The fatigue group had significantly more neurological impairment by higher scores on each subsets of UPDRS including mentation (P＜0.05),activities of daily living (P＜0.01) and motor (P＜0.01),while the subjects with fatigue had worse scores on SF-36 (P＜0.01).Multiple regression analyses showed that motor subset of UPDRS was the variable that had the predictive value for FSS score.The full model explained 6.4％ of the variance of the FSSscore (β=0.039,95％CI:0.019-0.059).However,other factors,including levodopa dosage,PSQ-Ⅰ,and ADAS-Cog score did not significantly contribute to the model.Conclusions Fatigue is a frequent symptom in carly,non-depressed patients with PD,affecting over 40％ of the patients in this cohort.The small correlation between fatigue and motor score,and the lack of association with dosage of dopaminergic treatment suggest that dopaminergic pathways might be only moderately involved in pathogenesis of fatigue.
