Objective To investigate the dementia caregivers' awareness of dementia diagnosis for patients aged≥80 years in veterans community in Beijing.Methods Patients aged 80 years and over who were diagnosed as dementia were selected from Dec.2009 to Jul.2011 in the veterans community in Beijing.A face-to-face interview and questionnaire survey were conducted in dementia caregivers individually,including basic social demographic data (gender,age,educational background),awareness rate of dementia,treatment and drug use situation and their attitude to dementia patients.Results A total of 118 caregivers were investigated individually.The caregivers in this study were mainly the spouse of the patients,and most of them were elderly people.46.6％ (55/118) of caregivers were the spouse of the patients,and 52.5％ (62/118) of caregivers were 65 years old and over.The caregivers' awareness rate of dementia was 32.3％ (38/118) when patients were diagnosed as dementia.There was no correlations of gender,age and educational background with the awareness rate of dementia diagnosis (all P＞0.05).50％ of dementia patients received the dementia treatment,and only 17.8％ (21/118) of patients got the first line drug treatment for dementia (acetylcholinesterase inhibitors and / or memantine).98.3 ％ (116 / 118) of caregivers agreed that the dementia patients should be treated kindly.Conclusions The dementia caregivers are mainly patients' spouse in veterans community and most of them are the elderly.The awareness rate of dementia diagnosis is low among the caregivers.Most patients do not take the formal treatment.The social support for the dementia caregivers should be strengthened.

Objective To determine the efficacy of individual cognitive training (CT) in the treatment of cognitive and neuropsychiatric symptoms in patients with mild to moderate Alzheimer disease ( AD). Methods A randomized, controlled, rater-blind clinical trial recruited 32 AD patients. AH patients were assigned to a CT group (n = 16) or a control group (a time and attention control, n = 16) for 10 weeks. All outcome measures were administered at baseline and follow-up. The cognitive status was evaluated using the Mini Mental State examination (MMSE) , a clock-drawing test (CDT) , Fuld's object memory evaluation (FOME) , a rapid verbal retrieval (RVR) , digit span assessments (DS) , block designing (BD), and the A version of the trail making test (TMTA). The patients' functional status was evaluated using an activities of daily living (ADL) scale. Any psychological and behavioural disorders were evaluated with the Neuropsychiatry Inventory ( NPI). Results Patients receiving CT showed greater average improvements in NPI total score, TMT-A score and MMSE total score than the controis at week 10. There was no statistically significant benefit for CT-treated patients in terms of ADL score. Conclusions Cognitive training can raise the NPI total scores and MMSE total scores of patients with mild to moderate AD.

OBJECTIVETo observe the clinical efficacy and safety on moderate and severe persistent allergic rhinitis treated with acupuncture.

METHODSSixty-six patients of moderate and severe persistent allergic rhinitis were randomized into an acupuncture group (34 cases) and a western medication group (32 cases). In the acupuncture, group, acupuncture was applied to Dazhui (GV 14), Feishu (BL 13), Pishu (BL 20), Ganshu (BL 18) and Shenshu (BL 23) in the prone, retained for 20 min; then in the supine, at Baihui (GV 20), Yintang (GV 29), yingxiang (LI20) Taichong (LR 3) and Hegu (LI 4), retained for 20 min. Acupuncture was given once every two days, three times a week, continuously for 8 weeks. In the western medication group, cetirizine hydrochloride was taken orally, 10 mg each time, once every day, continuously for 8 weeks. Separately, before treatment, after the treatment of 1 and 2 months and in 1 month after treatment, the total nasal symptom score (TNSS), the scores in the emotion rating scale for Ganzangxiang of TCM (ERSG) and the rhinoconjunctivitis quality of life questionnaire (RQLQ) were observed in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTS(1) For TNSS, the results after 1 and 2 months treatment and in 1 month after treatment were all, reduced as compare with that before treatment separately in the two groups (P < 0.05, P < 0.01) The result after 2 months treatment was lower than that after 1 month treatment in the acupuncture group (P < 0.05). In 1 month after treatment, the result in the acupuncture group was lower than that in the western medication group (P < 0.05). (2) For ERSG, the score after 2 months treatment was lower than that before treatment in the two groups (both P < 0.05). The score after 2 months treatment in the acupuncture group was lower than that in the western medication group (P < 0.05). (3) For RQLQ, the score after 1 month treatment was lower than that before treatment and the score after 2 months treatment was lower than that after 1 month treatment in the two groups (all P < 0.05). The score after 1 and 2 months treatment and in 1 month after treatment in the acupuncture group was lower than that in the western medication group separately (all P < 0.05). (4) The total effective rate was 91.2% (31/34) in the acupuncture group and was 90.6% (29/32) in the western medication group, without significant difference between the two groups (P > 0.05).

CONCLUSIONAcupuncture is the safe and effective intervention on moderate and severe persistent allergic rhinitis. Compared with the western medicine group, the efficacy in the acupuncture group presents much more advantageous at its durability.

Objective: To evaluate the effect of ICU mechanical ventilation patients with cluster nursing and conventional nursing, and provide the basis for the clinical work. Methods: Randomized controlled trials (RCTs) related to the ICU mechanical ventilation patients with cluster nursing and conventional nursing were collected through the databases such as CBM、CNKI, Wanfang Data, VIP Data. Meta-analyses were conducted for the included studies by the RevMan 5.3 software. Results: A total of 12 qualified research literatures were included, with a total sample size of 1478 cases, the test group 742 cases, the control group 736 cases. Meta-analysis showed that cluster nursing intervention can reduce the time of ICU patients with mechanical ventilation (Z=14.00, P<0.01), reduce the time at ICU (Z=41.89, P<0.01), reduce the incidence of ventilator associated pneumonia (Z=8.33, P<0.01) and reduce the patient mortality (Z=2.79, P<0.01). Conclusions The results of this meta-analysis showed that cluster nursing measures were statistically significant in reducing mechanical ventilation complications in ICU patients compared with conventional nursing measures. However, in view of the methodological quality and limitations of this study included in the literature. Suggestions for future research to carry out large sample, high quality, multicenter randomized controlled study, make the ICU mechanical ventilation in patients with cluster nursing measures to constantly update and perfect, as well as to seek more evidence-based nursing support evidence.

Objective To investigate the prevalence of cognitive and motor disorders as well as emotional and sleep abnormality in the veterans from military communities in Beijing. Methods The participants underwent a comprehensive in-person evaluation including detailed neuropsychological testing,Hospital Anxiety and Depression Scale and special questionnaires for movement and sleep disorders. Results The overall prevalence of cognitive impairment, extrapyramidal diseases was 32.7%, 8.8% . The prevalence of mild cognitive impairment, dementia, Parkinson disease, essential tremor, anxiety and depression was 26.2% , 6.5% , 2.0% , 6.1 % , 1.4% and 4.1% respectively. Prevalence of all kinds of sleep disorders ranged from 10. 3% to 53. 9%. The prevalence of cognitive impairment had no significant difference of sex, but were correlated to age and education, the correlation coefficient was 0. 326 and -0.221 ( P<0.01) . Conclusion Veterans from military communities had higher prevalence of cognitive impairment, extrapyramidal diseases and sleep disorders and lower that of anxiety and depression relatively.

Anti-Sry-like high mobility group box (SOX) 1 antibodies (abs) are partly characterized onconeural autoantibodies (autoabs) due to their correlation with neoplastic diseases. AntiSOX1 abs are associated with various clinical manifestations, including Lambert-Eaton myasthenic syndrome (LEMS) and paraneoplastic cerebellar degeneration (PCD). However, the clinical characteristics of patients with anti-SOX1 abs have not been described in detail. This review systematically explores the reported patients with anti-SOX1 abs and analyzes these cases for demographic characteristics, clinical features, coexisting neuronal autoabs, neuroimaging findings, treatment, and clinical outcomes. In addition, considering that PCD is the most common paraneoplastic neurological syndrome and that the association between PCD and anti-SOX1 abs remains unclear, we focus on the presence of autoabs in relation to PCD and associated tumors. PCD-associated autoabs include various intracellular autoabs (e.g., anti-Hu, anti-Yo, anti-Ri, and anti-SOX1) and cell-surface autoabs (anti-P/Q-type voltage-gated calcium channel). Commonly involved tumors in PCD are small-cell lung cancer (SCLC), gynecological, and breast tumors. LEMS is the most common clinical symptom in patients with antiSOX1 abs, followed by PCD, and multiple neuronal autoabs coexist in 47.1% of these patients.SCLC is still the predominant tumor in patients with anti-SOX1 abs, while non-SCLC is uncommon. No consistent imaging feature is found in patients with anti-SOX1 abs, and there is no consensus on either the therapy choice or therapeutic efficacy. In conclusion, the presence of anti-SOX1 abs alone is a potential predictor of an uncommon paraneoplastic neurological disorder, usually occurring in the setting of LEMS, PCD, and SCLC. The detection of anti-SOX1 abs contributes to an early diagnosis of underlying tumors, given the diversity of clinical symptoms and the absence of characteristic neuroimaging features.
