Objective To explore the effect of budesonide(BUD) on dendritic cell(DC) and airway inflammation in the asthmatic mice.Methods Forty female Kunming mice were divided into 4 groups:asthmatic model group,therapeutic control group,BUD treated group,and normal control group,with 10 mice in each group.Mice were sensitized by an intraperitoneal injection of 50 ?g ovalbumin(OVA) adsorbed to 1 mg aluminum hydroxide dissolved in 0.2 mL saline.Animals were boosted on the 14th day in the same way.From the 21th to 35th days,and mice were challenged with 10 g/L aerosolized OVA for 30 min a day to establish a murine model of asthma.To evaluate the effect of BUD,60 minutes prior to OVA exposure,the mice were treated with 1 mg aerosolized BUD or placebo(saline).Control animals were sensitized intraperitoneally with saline and challenged with aerosolized saline alone.Eosinophil(EOS) count,degree of mucus secretion and DC count around the airways were measured by haematoxylin and eosin staining,periodic acid schiff's staining,immunochemistry technique and computerized image analysis system.Results In asthmatic model group,EOS count,DC count and the degree of mucus secretion around the airways were increased compared with nomal control group(P_a0.05).In BUD treated group,EOS count,DC count and the degree of mucus secretion around the airways were decreased compared with the asthmatic model group(P_a

Objective To investigate the clinical effect of preoperative nutritional treatment and perioperative nutrition support for the patients with esophageal cancer.Methods According to the digital table,90 patients with esophageal cancer were divided into the control group(15 cases),preoperative nutrition group(25 cases),postoperation nutrition group(25 cases)and preoperative nutrition + postoperation nutrition group(25 cases).The postoperative quality of life and the complications were compared.Results Postoperative quality of life in the preoperative nutrition group,postoperation nutrition group and preoperative nutrition + postoperation nutrition group were all better than that in the control group(t =14.76,15.13,17.87,all P ＜ 0.05).The incidence rate of postoperative complications in patients received nutritional intervention significantly decreased than in the control group(x2 =9.17,12.13,19.18,all P ＜ 0.05).Conclusion The preoperative nutrition and postoperation nutrition can improve the postoperative quality of life and reduce the incidence rate of the complications.

BackgroundCataract is a leading blinding eye disease,and the prevalence of cataract varies in different regions.ObjectiveThe present study was to investigate the incidence of cataract,surgical coverage rate of cataract and postoperative visual acuity,and to propose a strategy for blindness prevention in Chifeng Keshiketengqi.Methods This is a cross-sectional survey of research.A random cluster sampling method was performed in 12 populated areas in Keshiketengqi.Inhabitants over 50 years in the region were included in this survey.This study was approved by the Ethic Committee of Inner Mongolia People' s Hospital.Informed consents were obtained orally from all the subjects.Disease history,visual acuity,intraocular pressure and regular ophthamological examinations were performed.The inclusion criteria of a pilot study and detailed protocol were employed to calculate the incidence rate of cataract.The questionnaire survey was simultaneously adopted to analyze the cataract-related factors.The surgical coverage rate of cataract in this area was calculated.ResultsIn a total 4234 inhabitants,3826 subjects participated in the survey with a response rate of 90.36％.Cataract was found in 1200 participants with an incidence rate of 31.39％.Age,the female gender and illiteracy were identified as risk factors for cataract (x2 =101.005,P =0.000 ;x2 =58.853,P =0.000 ;x2 =12.037,P =0.007 ).The prevalence rates of cataract were 36.98％ and 33.56％ for illiterates and women,respectively.The incidence rate in the Mongol population was significantly higher than that of the Han population ( 34.83％ vs.29.76％ ) (x2 =9.734,P =0.001 ).The cataract surgery rate increased yearly since 1998.When the vision acuity of the fellow eye was ＜0.1,the surgery coverage rate was 20.60％,but the rates were lower in female,illiterates and the Mongol population (x2 =1.993,P =0.038 ;x2 =16.463,P =0.044 ;x2 =8.523,P =0.029).When a pinhole visual acuity of ＜0.05 was determined as the criteria of blindness,the surgical coverage rate was 28.36％.The cataract surgical coverage rates for Han and Mongolian were 30.67％ and 24.53％,respectively,with a significant difference between them (x2 =12.951,P=0.000).The social burden rate was 3.34％ in this area,with a majority of females,illiterates and the Mongol population ( P＜0.05 ).ConclusionsIn agricultural and pastoral areas of Chifeng Keshiketengqi,the ≥50 years old population has a high rate of cataract blindness and low surgery coverage rate.Surgery is still the preferred way for cataract treatment.

Objective To observe the delayed brain myelination of children with phenylketonuria(PKU)combined with epilepsia,and explore effectiveness of the treatment and provide an objective criteria for patient recovering evaluation.Methods There were 42 PKU patients,aged 3 to 72 months were selected.The concentration of phenylalanine tested by high pressure liquid chromatography was greater than 1.2 mmol/L in blood,diagnosed as PKU.According to electroencephalogram and clinical symptom,21 cases were diagnosed as epilepsy,the other 21 cases were used as control group.All patients were taken MRI before treatment.Myelination in 10 sections(cerebellum,pons,mesencephalon,internal capsule posterior limb,corpus callosum,internal capsule anterior limb,occipital lobe,parietal lobe,temporal lobe,frontal lobe)were evaluated.Results Delayed myelinations were located mainly in the cerebral lobes and corpus callosum,average delayed incidence of the 10 region was 44.8% in epilepsy group and 30.9% in control group.The incidence of the corpus callsum was 80.9% in epilepsy group,52.4% in control group,the number of sections of delayed myelination showed statistically significant between 2 groups(P
