Objective To investigate the status and influencing factors of pleasant events among community-dwelling dementia patients. Methods Totally 266 community-dwelling dementia patients were recruited from Bei-jing,Guangzhou and Tianjin,and were investigated with the Chinese-version Pleasant Events Schedule-AD(PES-AD). Results The overall score of PES-AD was (14.0±6.7). The factor scores from high to low were sensory stimulation activities(0.9±0.5),family activities(0.8±0.5),emotional stimulation activities(0.8±0.4) and autonomy activities(0.6± 0.5). Multiple linear regression showed that the severity of disease,without chronic disease,educational level of de-mentia patients and their caregivers were significant influencing factors of pleasant events,which explained 41.1% of the total variance. Conclusion Sensory stimulation activities of community-dwelling dementia patients were relatively satisfactory,followed by family activities and emotional stimulation activities,but autonomy activities were relatively unsatisfactory. It is suggested to choose appropriate pleasant activities according to the severity of disease for de-mentia patients to improve their quality of life.

Objective We characterized the clinical features of sporadic Creutzfeldt-Jakob disease(sCJD)in or?der to diagnose it at the early stage. Methods Seventeen patients with sCJD were enrolled in the study. The clinical data, symptoms at the early stage, result of auxiliary examinations and survival time were analyzed. Results The ratio of male to female was 1:1.83 and the average age of onset was 60 ± 8.8 years old. Most of them presented with walking unstable (82.4%)and hypomnesia (64.7%) as the initial symptom. The occurrence rate was 82.4%, 76.5%and 58.8%for myoclo?nus, colored-ribbon-shaped high signals in cerebral cortex and high signals in basal ganglia of MRI. Periodic synchro?nous discharge (PSD) of electroencephalography(EEG) was seen in 82.4% cases, while cerebrospinal fluid analysis re?vealed positive results for 14-3-3 protein in 70%cases. Twelve patients had been dead in our study. The median surviv?al time was 12±7.7 months. Conclusions sCJD is more frequently occurred in mid-aged and older without specific symp?toms in early stage and positive rate of high signals in cerebral cortex of MRI and PSD of EEG is high.

Purpose The aim of this study was to compare the pharmacokinetic(PK) profile and relative bioavailability of two sustained release tablets containing 10 mg mizolastine in healthy, young Chinese volunteers. Methods A single oral dose of mizolastine was given under fasting conditions to volunteers aged from 21 to 24 years in this open-label, randomized, crossover study. A ten-day washout period was applied between each of the two formulations. Plasma samples were obtained before dosing and at predetermined time points after dosing up to 48 hours and were analyzed for plasma concentration with a high-performance-liquid chromatography-UV method. PK parameters representing the extent and the rate of absorption of mizolastine were obtained. An analysis of variance, 90% confidence intervals, and two one-sided tests were employed for statistical analysis of relative difference between the two formulations. Results According to the pharmacokinetic and statistical analysis, parameters were not statistically different between the two formulations except the peak concentration (cmax). The point estimates of the ratios of AUC0→t, AUC0→∞ of mizolastine were (101.26 + 9.82) % and (102.52 + 8.61)% with 90% confidence intervals (CIs) of 95. 5% - 106. 5% and 97. 7% -106.9% respectively, comprised in the stipulated 80% - 125% range; for cmax values, the ratios was 82.17% - 15.32% with the 90% CIs of 71. 7% - 91.1%, fell in the recommended range of 70% -143%. Conclusions The results indicate that there is no statistically significant difference in PK parameters except cmax between the two sustained release tablets of mizolastine. The 90% CIs of AUC0→t,AUC0→∞ and cmax are within the predefined range. Thus, the two sustained release tablets of mizolastine are considered bioequivalent and generally well tolerated.

Background:MicroRNAs ( miRNAs ) is a class of small non-coding RNAs that regulate gene expression at posttranscriptional level. They are considered to play a critical role in the tumorigenesis and development of various tumors. Aims:To identify the recurrence-specific miRNAs in peripheral blood of patients with recurrent colorectal adenoma by miRNA array for providing sensitive and specific molecular markers for recurrence prediction. Methods:Fifty colorectal adenoma patients who had undergone polypectomy by colonoscopy were re-examined from Aug. 2012 to Sep. 2013. Four recurrent and four non-recurrent patients were selected and miRNA array was used to detect the expression profiles of miRNAs in peripheral blood samples. Differentially expressed miRNAs were identified between recurrent and non-recurrent patients. Real-time PCR was applied to verify the differentially expressed miRNAs identified by microarray. Results:Seven up-regulatedmiRNAs(hp hsa-miR-548ai,hsa-miR-4446-3p,hsa-miR-139-3p,hsa-miR-27a-5p,hsa-miR-10a,hsa-miR-23a and hsa-miR-486-3p)and 4 down-regulated miRNAs( hsa-miR-124,hsa-miR-3613-5p,hsa-miR-495 and hsa-miR-485-5p)were identified by microarray between recurrent and non-recurrent patients. Among them,seven miRNAs were validated by real-time PCR as consistent with microarray. Conclusions:Some differentially expressed miRNAs may be involved in the recurrence of colorectal adenoma,which gives clues for further investigation on recurrence predictors.

Objective:To evaluate the clinical outcomes of 2 kinds of osteocutaneous flap in the treatment of mandibular osteoradione-crosis.Methods:35 cases with mandibular osteoradionecrosis were treated by partial mandibulectomy and bone graft according to de-fect size and patients'requirements.The defects in 7 patients were reconstructed with iliac osteocutaneous flap and 28 with fibular os-teocutaneous flap.All flaps and wounds were monitored regularly.Results:One flap with venin crisis was observed in the patients treated with iliac osteocutaneous flap,its skin island was failed but the bone graft was survived.In the fibular osteocutaneous flap group,3 flaps with vein crisis were observed.2 of them were failed and 1 was rescued after second surgery.The most common compli-cations were infection,delayed wound healing and scar.The appearance and function were all satisfied and limitation of mouth opening was improved after surgery.Conclusion:Both of fibular osteocutaneous flap and iliac osteocutaneous flap can be applied in the defect reconstruction of patients with mandibular osteoradionecrosis.Fibular osteocutaneous flap is a good choice for huge mandibular defect and iliac osteocutaneous flap seems more esthetical.
