Objective To test the reliability and validity of the Chinese version of Quality-of-Life Questionnaire for Mechanically Ventilated Patients (QOL-MV). Methods The English version of QOL-MV was revised and translated into Chinese version. The reliability and validity of the Chinese version of QOL-MV was tested in 120 mechanically ventilated patients. Results The Cronbachαcoefficient of the Chinese QOL-MV was 0.904. The item-level content validity index of Chinese QOL-MV were 0.86-1.00 and the scale-level content validity index of Chinese QOL-MV was 0.92. Two factors were extracted by factor analysis and the cumulated variance was 80.18%. The dimensional factor loading of each item was greater than 0.565. The correlation coefficient between the score of Chinese QOL-MV and the Euroqol Group′s 5-domain 3 Level Questionnaire (EQ-5D) and Richards Campbell Sleep Questionnaire (RCSQ) was 0.947 and 0.561 respectively (P<0.01). Conclusions The Chinese version of QOL-MV has been proved to be reliable and valid.It can be used to measure the quality-of-life for mechanically ventilated patients.

Objective To investigate the association between diet during pregnancy and hypertensive dis-order complicating pregnancy ( HDCP ) , so as to provide a theoretical basis guiding appropriate diet during pregnancy.Methods Using 1∶2 matched case-control study method, we selected pregnant women delivered in Anhui Women and Child Health Care Hospital from January to December 2014, and interviewed them with food frequency questionnaire.The relationship between intake frequency of various food and HDCP was analyzed. Results A total of 543 women were included in this study, including 181 cases and 362 controls.Mann-Whit-ney U test results showed that the frequencies of meat and fish, eggs, beans, nuts, milk, and pickled food con-sumption were significantly different between the cases and the controls (all P<0.05);while the differences in cereals, vegetables, and fruits consumption frequency between cases and controls were not statistically signifi-cant (all P>0.05).Multivariate Logistic regression analysis showed that higher intake frequencies of beans (OR=0.746, 95%CI:0.645-0.862), eggs (OR=0.789, 95%CI:0.693-0.898), and milk (OR=0.822, 95% CI:0.725-0.931) were associated with lower risk of HDCP; in contrast, higher intake fre-quency of pickled food was associated with higher risk of HDCP (OR=1.190, 95% CI:1.054-1.344). Conclusions Beans, eggs, and milk may be protective factors for HDCP, while pickled food may be risk fac-tor of HDCP.Diet during pregnancy should be appropriate and following scientific guidelines.

18F-2-fluro-D-deoxy-glucose (18F-FDG) is used by positron emission tomography/computed tomography (PET/CT) examination as an imaging agent,by observing the uptake of the agent of the lesion to determine its metabolism,and make a diagnosis.It can provide anatomical and functional at the same time,not only qualitative but also position and can significantly improve the accuracy of diagnosis.Currently PET/CT has been widely used in the clinical aspects of the differential diagnosis of benign and malignant tumors,prognostic assessment and so on.The property of pleural effusion is important to the treatment and prognosis of the disease.

Professional postgraduates in geriatric medicine are one of the most important re-courses of geriatric specialists. However, training model for geriatric postgraduates is still unclear in China. In general, geriatric medicine has no independent training plan, and is included in internal medicine training. Such model cannot represent the feature of geriatric medicine. The present paper aimed to discuss the ability construction for geriatric postgraduates based on the geriatric medicine specialist training experience both at home and abroad, including diagnosis and treatment of multi-system diseases, ability of geriatric assessment, management of geriatric syndromes, consultation for geriatric rehabilitation and ability for continuity health service in order to cultivate the compound tal-ents suitable for the aging society requirement for geriatric medicine in China.

Objective The poor sleep quality of epileptic patients may be partly due to the occurrence epileptiform discharges (EDs).We observed the number of interictal discharges in each sleep stage and explored the associations between EDs and sleep phases in epilepsy patients.Methods Two hundred and forty epileptic patients and 213 healthy volunteers were enrolled in the current study.For all subjects,video-electroencephalogram monitoring and 24 h-night polysomnography were conducted to detect EDs and analyze the sleep structures.Results EDs were detected in 88.7％ (213/240) of epilepsy patients with the most frequent cases from the temporal lobe.The EDs detected during waking,sleeping,or both waking and non-rapid eye movement (NREM) sleep stage accounted for 20.6％ (44/213),40.4％ (86/213),and 38.9％ (83/213) of the total patients,respectively.The total sleep time and time spent in REM were similar between the epileptic patients and healthy volunteers.However,epileptic patients spent a significantly longer mean sleep time in NREM Ⅰ-Ⅱ ((304 ±39) min versus (225 ±29) min,t =3.51,P =0.000) and less in NREM Ⅲ-Ⅳ ((49 ± 7) min versus (133 ± 17) min,t =2.30,P =0.000) than healthy volunteers.Furthermore,asymmetric sleep spindles and fragmentary sleep structure as well as high inversion frequency were found in epilepsy patients,respectively.Conclusion Combination of long-term video electroencephalogram with polysomnography is a useful method to analyze associations between EDs and the sleep-wake cycle.This strategy can also help identify the nature of sleep disorders in epileptic patients,which may improve the treatment efficacy.

Objective To investigate the association between concentrations of environmental air pollutants and the daily number of outpatient visits for urticaria in Beijing. Methods Time series analysis in combination with distributed lag non?linear model(DLNM)and Spearman′s rank correlation test was used to analyze the association between PM2.5 concentrations and the daily number of outpatient visits for urticaria. All effect estimates were expressed as a risk ratio(RR)for the daily number of outpatient visits with an interquartile range(IQR)increase of 82.8 μg/m3 in PM2.5. Results From January 1st 2013 to June 30th 2014, the daily average PM2.5 concentration, temperature, relative humidity and number of visits for urticaria were 89.3 μg/m3, 12.7 ℃, 51.9% and 27.3 respectively. Spearman′s rank correlation test showed that the daily average PM2.5 concentration and number of visits for urticaria were correlated with daily mean temperature(rs =-0.21, 0.36, respectively, P < 0.05)and relative humidity(rs = 0.49, 0.31, respectively, P < 0.05), but no correlation was observed between daily average PM2.5 concentrations and daily number of visits for urticaria(rs=0.01, P>0.05). There was no significant correlation between daily number of outpatient visits for urticaria and daily PM2.5 concentration lagged by 0-14 days(RR=1, 95%CI:0.89, 1.13). After potential confounding factors were adjusted, an 82.8μg/m3 increase in daily PM2.5 concentration at lag 0-20 days was significantly associated with a 22%(95%CI:3%, 46%)increase in daily number of outpatient visits for urticaria, suggesting that the lagged effect of PM2.5 was obviously increased. Conclusion The association between PM2.5 concentrations and the number of visits for urticaria is easily affected by meteorological factors and biological confounding factors, and relative humidity and mean temperature are both positively correlated with the number of visits for urticaria.

Objective To investigate the association between air pollution and the daily number of outpatient visits for dermatitis in Beijing city, and to evaluate the sensitivity to air pollution in populations of different gender and age. Methods Time-series data on daily outpatient visits for dermatitis between April 2012 and April 2014 were collected from Air Force General Hospital of PLA. The daily average concentrations of sulfur dioxide (SO2), nitrogen dioxide(NO2), and particulate matters(PM2.5, PM10)were obtained from Beijing Municipal Environmental Monitoring Center, and routine meteorological data (including daily mean temperature, relative humidity and wind speed)were collected from the China Meteorological Data Sharing Service System. A generalized additive model was used to analyze the association between daily average concentrations of air pollutants and the number of daily outpatient visits for dermatitis. Results In single-pollutant models, an increase of 10 μg/m3 in daily concentrations of PM2.5, PM10, SO2, and NO2 was associated with the number of outpatient visits for dermatitis with the relative risk being 1.003 1 (95% CI, 1.001 6 - 1.004 5), 1.0025 (95% CI, 1.001 4 - 1.003 7), 1.0057 (95% CI, 1.001 5 - 1.009 9)and 1.009 7 (95% CI, 1.005 6 - 1.013 8)respectively. Similarly, multipollutant models showed that air pollutant concentrations were significantly associated with the daily number of outpatient visits for dermatitis. Distributed lag models showed that the effects of PM2.5, PM10 and NO2 on daily outpatient visits for dermatitis were mainly observed on the day of exposure, while the effect of SO2 increased along with the increment of lag days. Stratification analysis showed that people aged less than 60 years and females were relatively more sensitive to particulate matters (PM2.5, PM10), while NO2 affected all groups of people at the same degree, and SO2 mainly affected people aged 35 - 60 years. Conclusion Air pollutants PM2.5, PM10, SO2 and NO2 may all increase the risk of dermatitis in Beijing area.

Objective To survey the prevalence of stress urinary incontinence(SUI)and related knowledge among postpartum women in Shanghai Melong district.Methods A questionnaire survey on the knowledge of stress urinary incontinence was conducted among 317 postpartum women who were home visited by Meilong Community Health Service Center between March 2017 and June 2017.The self-designed questionnaire included the general situation(age, height, weight, occupation, menstrual history), pregnancy and childbirth, and knowledge of SUI; the International Consultation on Incontinence Questionnaire Short form(ICIQ-SF)was also used.Total 317 questionnaires were distributed and 313 valid ones were retrieved(98.73%).Results The prevalence of SUI in the participants was 26.84%(84/313).Multivariate logistic regression showed that BMI≥24 kg/m2(OR=6.24, 95% CI: 3.41 -11.41), complicated metabolic syndrome(OR=9.84, 95% CI: 2.77 -34.96)and birth weight of previous child ≥4 kg(OR=0.09,95%CI:0.04-0.19)is independent risk factors for the development of SUI.The average SUI knowledge score was(10.39 +8.65)points, only 26.20%(82/313)of the participants knew Kegel training(score 5.99 ±1.60).The SUI knowledge level of postpartum women was associated with educational level(F=12.41),occupation(F=9.06), income(F=4.05), reproductive history(F=10.98)and presence of urinary incontinence symptom(F=22.31)(all P<0.05). Conclusion The knowledge level of maternal stress urinary incontinence in Meilong district is relatively low,and the publicity of SUI and pelvic floor rehabilitation knowledge should be enhanced for the pregnant women.

Methods By convenience sampling, 160 residents living in the nursing home of suzhou city (mean age 60 or higher) were selected, and demographic data were collected by using a homemade questionnaire, their cognitive function was investigated by using the Montreal Cognitive Assessment Scale. Results Single factor analysis showed that the score of the elderly who often use smart products in every cognitive field and overall cognitive function were superior to those who could not use smart products,the difference was statistically significant(t=-4.47--2.15,all P<0.05).The scores of the elderly with hobbies were higher in the overall cognitive function and the other six areas except the orientation, than those who had no hobby,and the differences were statistically significant(t=-6.80--1.81,all P<0.05).After adjusting for age,gender,body mass index(BMI),cultural level,often using smart products in total cognitive function in the elderly(t=4.842,P<0.01)and executive function(t=4.008,P<0.01),attention(t=3.045,P=0.003), abstract(t=2.135,P=0.034),delayed recall(t=3.759,P<0.01),the directional(t=2.866,P=0.005)of the five areas showed significant correlation. The total cognitive function of the elderly with hobbies (t=3.496, P = 0.001) and the visual spatial execution function (t=3.316, P = 0.001), naming (t=3.241, P =0.001), abstract (t=2.643, P = 0.009), and delayed recall (t=2.073, P= 0.04) were all significantly correlated.Conclusions Often using smart products and having certain hobbies are protective factors of cognitive function,build corresponding intervention plans for the future,by cultivating the elderly hobby, guiding the elderly using intelligent products and other measures to achieve successful aging, slow the cognitive decline,thus reducing the risk of mild cognitive impairment.

Objective To investigate the cognition influencing factors of regular laboratory monitoring of HBeAg negative in chronic HBV infection,and analyze the related factors of HBeAg conversion. Methods From January 2015 to March 2017,a total of 302 chronic HBV infected patients in Jinin Infectious Disease Hospital were investigated with a questionnaire about disease related cognition. Single factor and multiple factors Logistic regression analysis was used to analyze the influencing factors of regular monitoring behavior and HBeAg conversion. At the same time,163 cases of HBeAg negative HBV infection were divided into the two groups: regular and irregular monitoring, and disease related laboratory tests and the outcomes were analyzed. Results Psychological pressure(OR = 4. 339, 95％ CI:1. 322 - 14. 243),antiviral treatment( OR = 5. 149,95％ CI:1. 628 - 16. 283),knowledge of hepatitis B (OR = 3. 306,95％ CI:1. 108 - 9. 867) and the stability of disease(OR = 3. 229,95％ CI:1. 094 - 9. 528) were the regular monitoring promoting factors(all P < 0. 05). Antiviral therapy(OR = 0. 298,95％ CI:0. 108 - 0. 822),virus gene mutation(OR = 0. 202,95％ CI:0. 048 - 0. 856),and duration of disease(OR = 0. 340,95％ CI:0. 122 - 0. 949) were related factors of HBeAg conversion(all P < 0. 05). The serum levels of ALT,ALB,AFP and HBV - DNA in the HBeAg negative regular monitoring group were (68 ± 34) IU/ L, (40 ± 12) g/ L, (23. 0 ± 5. 9) μg/ L, (2. 0 ± 1. 3)copies/ mL,respectively,which in the non - regular monitoring group were (126 ± 56) IU/ L,(35 ± 10) g/ L, (78. 0 ± 12. 8)μg/ L,(3. 9 ± 1. 7) copies/ mL,respectively,the differences were statistically significant (t = 2. 323, 2. 097,2. 109,2. 234,all P < 0. 05). Conclusion HBeAg negative patients is a key group to monitor and control disease progression. Regular laboratory monitoring is better. Medical staff should enhance patients' cognition education and improve disease control rate.
