Objective To assess the clinical effects of uterine arterial embolization on uterine leiomyoma.Methods We treated 21 patients with uterine leiomyoma by Seldinger's uterine arterial embolization. The 4.0 F Cobra catheter was placed into the double uterial arteries with Polyvinyl Alcohol Foam(PVA) particles as the embolizer. At 3 and 6 months postoperatively, we investigated the effects of the embolization. Results After uterine arterial embolization, the volume of uterine leiomyoma decreased and menorrhagia was under controlled. The symptoms of anemia and oppression were relieved. The physiologic functions of ovary and uterus were preserved completely.Conclusions Uterine arterial embolization is an effective and less invasive way to treat uterine leiomyoma.

Objective To examine the effect of donepezil on cognitive function of Alzheimer's disease from a naturalistic observation in memory clinic.Methods From the subject pool in memory clinic,thirteen patients with mild to moderate Alzheimer's disease(meeting NINCDS-ADRDA criteria of probable AD)were enrolled in the naturalistic observation.Donepezil with dosage of 5 mg daily Was administered.Cognitive Ability Screening Instrument (CASI)Was used to assess the cognitive function,and was administered at baseline,3 and 6 months after treatment with donepezil.Resuits After 6-month treatment with donepezil,the change of score of verbal fluency from baseline Was significant[(4.3±3.1)vs(6.2±2.7),P＜0.05].There was a trend that constructional praxis was also improved after 6-month treatment(P=0.06).The change of scores of other cognitive domains remained the sanle(P＞0.05).Conclusion In the naturalistic observation at memory chnic,donepezil may improve verbal fluency of AD patients,and keep most cognitive function stable.

Objective: To determine the cognitive function and MRI-based measurement of MTL structures in patients with Alzheimer disease (AD) and to find a sensitive cognitive marker or specific MRI-based measurements for early diagnosis of AD. Method:Fifty-two AD patients, 27 VD (vascular dementia) patients and 35 aged matched normal control were recruited. The cognitive functions were evaluated with Alzheimer disease assessment scale-Cognitive portion (ADAS-Cog), Wechsler memory scale-revised and Mini-Mental Status Examination (MMSE). MTL structures, including hippocampal formation, amygdala and parahippocampal gyrus, were measured by MRI volumetric measurements. Result: Compared with VD patients and healthy controls, there was more pronounced reduction of performance on the main cognitive domains in AD patients, which indicated the diffused deficits of AD, including learning and memory, comprehension, language, orientation and concentration. The atrophy of MTL structures was more prominent in AD patients. A moderate diagnostic accuracy of 83.3% was achieved by Fisher's linear discriminant model, which comprised the scores of word recall, recall of test instructions, commands, constructional praxis and orientation in ADAS-Cog, and the performance on picture recall, visual recognition visual reproduction, logic memory and touch test in Wechsler memory test and part of memory in MMSE. In diagnose of AD, MRI based volumetry of left temporal horn of lateral ventricle and amygdalohippocampal complex had the sensitivity of 78.4% and accuracy of 77.1%. When cognitive indicators were combined with MRI based measurement, the diagnostic accuracy increased to 90.5%. Conclusion: AD produces more diffused cognitive deficit and severer atrophy of MTL structure. Combination of cognitive indicator with MRI based measurement can improve accuracy in diagnosis of AD.

Objective: To investigate the effect of Nano-Se with lower toxicity on the anti-tumor effect of cisplatin. Method: For toxicity comparison, mice were orally administered Nano-Se and sodium selenite to observe death, body weight loss and liver injury. As to the protective effect of Nano-Se on the toxicity of cisplatin, mice with and without Nano-Se supplementation were injected cisplatin to observe death and body weight loss. For evaluation of whether Nano-Se influence the anti-tumor effect of cisplatin, Lewis lung carcinoma was transplanted into mice, and the survivor and tumor volume were recorded to compare the effect of Nano-Se supplementation on cisplatin. Results: The toxicity of Nano-Se is significantly lower than sodium selenite. Nano-Se can decrease toxicity of cisplatin without compromising its anti-tumor effect. Conclusion: Nano-Se with lower toxicity can improve the therapeutic effect of cisplatin.

Objective:To examine the discriminatory potential of the ADAS-Cog, Chinese version for mild and moderate Alzheimer's disease (AD). Methods:Patients with AD (199 mild AD and 106 moderate AD) meeting the NINCDS-ADRDA criteria of probable AD were recruited. The Chinese version of ADAS-Cog was administered to all AD subjects. Results:The total score of ADAS-Cog and the score of each ADAS-Cog item differed significant-ly between mild and moderate AD groups, with higher scores in moderate AD group. GLM analysis showed insignifi-cant influence of age or educational level on the ADAS-Cog total score. These results indicated that ADAS-Cog could represent the distinctive profiles of cognitive impairment between mild and moderate AD. The results of Logis-tic regression analysis showed that the item score of orientation and constructional praxis as well as the ADAS-Cog total score could classify mild and moderate AD efficiently, with a sensitivity of 78% - 82% and a specificity of 70% - 73%. Conclusion:Our results indicate that the Chinese version of ADAS-Cog is useful for staging of AD. It is recom-mended that the Chinese version of ADAS-Cog be introduced for monitoring the AD drug therapeutic efficacy on cognitive impairment among Chinese AD patients.psychiatry Alzheimer's disease

OBJECTIVE: To estimate the prevalence of allergic rhinitis (AR) in a community center in Beijing. METHOD: We randomly investigated a community with 13 900 inhabitents in Beijing by means of questionnaire survey. RESULT: A total of 2000 questionnaires was send out, and 1988 of them were collected, which included 952 males and 1036 females (age: 1 to 96 years old, 128 cases are younger than 14 years old. Among of them, 194 cases (9.76%) were diagnosed as having AR according to epidemiologic definition, including 14 children. The prevalence of AR was 9.68% in adults, with male 10.21% and female 9.18%, 10.94% in children. The prevalence in male are slightly higher than in female both with adults and children but without statistic significance. CONCLUSION The survey showed the incidence of AR in Beijing are 9.76% in population, adults 9.68%, children (younger than 12) 10.94%. AR patients are more likely to have other allergic diseases.

Objective:With selenomethionine as reference,we investigated the bioavailability and toxicity of methylselenocysteine. Method:Selenium retention,glutathione peroxidase and thioredoxin reductase activities were tested to compare bioavailability. Acute toxicity and short-term selenium-tolerance were studied to compare toxicity. Results:Selenomethionine and methylselenocysteine were comparable in ability of increasing selenoenzymes. Selenomethionine caused much higher selenium retention,especially at higher levels and lower toxicity indicated by acute toxicity and short-term selenium-tolerance. Conclusion:Compared with selenomethionine,methylselenocysteine has equal efficacy on selenoenzymes with the characterization of less retention,but higher toxicity.

Objective To investigate the refraction change and nursing character in myopic amblyopia during the perceptual learning treatment. Methods Refraction of 54 children (98 eyes) with myopic amblyopes were selected,which were selected from the amblyopia clinic between 2007 and 2009, the spherical diopter, astigmatism and spherical equivalent were collected before and after perceptual learning,the refractive dynamic was compared according to the degree of amblyopia. Results The spherical average annual growth of myopic amblyopia during treatment was 0.52D, the growth of astigmatism was 0.03D;the spherical equivalent average annual growth was less than 0.50D accounted for 57.14%. The dynamic changes of spherical or SE of mild, moderate and severe amblyopia had significant difference, but the cylinder had not significant difference in change. Conclusions The treatment of perceptual learning in patients has little effect on the growth of refraction in myopic amblyopia, however, it is still necessary to pay close attention to refraction changes of in myopic amblyopia in the course of treatment.

Objective To retrospectively investigate the characteristics of patients with inflammatory bowel disease (IBD)in last 10 years in Kunming city. Methods Four hundred and thirty consecutive patients with IBD, who had hospitalized in 7 hospitals between January 1998 to March 2007, were investigated. Among them, 379 patinets had ulcerative colitis (UC) and 51 had Crohn's disease (CD). The patients who received coloscopy, histopathological and bariam enema examination accunted for 98.2%, 56.2% and 2.6% in UC group,respectively, and 72.5%,78.4% and 31.4% in CD group,respectively. The gender, age, occupation and the clinical manifestation of the patients, and the results of the colonoscopy and pathological examination were analyzed. Results Most of the UC patients were aged 30 to 39 years and 50 to 59 years with average age of (46.9±15.8) years, whereas CD patients were aged 20 to 29 years with average age of (41.6±17.2)years. The male and urban patients were predominat in both UC and CD groups. Mental workers were common in UC group. The symptoms of diarrhea (302,79.7%), abdominal pain (285,75.2%) and bloody stools (290,76.5%) were major events in UC patients, and those of abdominal pain (44,86.3%), diarrhea (28,54.9%) and weight loss (28,54.9%) were major events in CD patients. The coincidence ratio among colonoseopy, histopathology and bariam enema examinations was 88.4 % ( 329/372 ), 24.4 % ( 52/213 ) and 4/10 in UC patients, respectively, and 86.5%(32/37), 27.5%(11/40) and 75%(12/16) in CD patients, respectively. All of the UC patients were in active stage of disease,including 38.3 % in mild,42.2% in moderate and 19.5% in severe. In CD group, 7.8% was in relief stage and 92.2% in active stage,including 15.7% in mild,43.1% in morderate and 41.2% in severe.Conclusion The understanding of prevalence and clinical characteristics of IBD in last 10 years in Kunming city will be helpful in diagnosis and treatment of the disease.

Objective To investigate the distribution pattern of the ADAS-Cog scores among the elderly in Beijing and to evaluate the application of ADAS-Cog in distinguishing patients with mild Alzheimer's disease (AD) and healthy elderly. Methods In total, 1616 healthy elderly (NC), 125 elderly patients with non-AD disorders (ND), and 310 patients with probable AD including 201 patients with mild AD and 109 patients with moderate AD (by NINCDS-ADRDA criteria) were recruited in the study and their cognitive performance was measured by the ADAS-Cog.Results In NC group, those older than 80 years and those with less than 5 years schooling scored highest. There was statistically significant correlation between the total scores of the ADAS-Cog and age and duration of schooling in NC group (F=14.34, 113.27,both P<0.01). No correlation was suggested in the mild AD group. The total score of ADAS-Cog was significantly associated with duration of schooling in both moderate AD and ND groups (F=4.18, 8.72, both P<0.05). The total score of ADAS-Cog differentiated the patients with mild AD from NC healthy elderly with AUC ranging from 0.69 to 0.82 in each subgroup by age, and from 0.75 to 0.88 in subgroups by durations of schooling with the highest AUC of 0.88 in the subgroup having more than 15 years of schooling education. Conclusions The ADAS-Cog score in the healthy elderly is significantly associated with age and duration of schooling education. The ADAS-Cog can be applied in the cognitive assessment of Chinese AD patients. The total score of ADAS-Cog could efficiently differentiate patients with mild AD from healthy elderly, especially in subjects with higher education level.
