Objective:To investigate the supply status of dementia care services in pension agency in Guang zhou,thus to put forward suggestions for improving the service quality of the long-term care for dementia.Methods:Using questionnaire research and individual interview,an interview survey was conducted among managers,dementia and nursing assistant in ten pension agencies in Guangzhou.The data was analyzed by SPSS16.0 statistical method.Results:The dementia had been increasingly paid attention by the pension agencies,but there were still considerable defects in the aspect of the zone set up and service supply;the professional quality of nursing personnel in pension agencies had steadily increased,but shorthanded situation was more obvious.Conclusions:It suggests that we should provide specialized nursing level and the classification standard of care requirements for dementia elders;strengthen the training of mental health worker to enhance the level of medical care and supply ability of nursing assistant;allocate the mental health resources rationally;explore the “combination of medical treatment and endowment” service model which meets the need of dementia elders.

Objective To explore the causes of per-hospitalization high inpatient expenditure of a tertiary hospital in 2015,by analyzing the influencing factors.Methods We retrospectively studied 1 282 inpatient cases who cost more than 100 000 yuan per case at a tertiary hospital in 2015,analyzing statistically major influencing factors of such expenditure in variance analysis and multiple stepwise regression analysis.Results The average days of stay of these cases were 27.6 days,and the average medical cost of those cases was 149 153 yuan per person.Costs for medicines and material made up a large proportion of medical costs,respectively accounting for 33.38% and 31.98% of the total.The days of stay,prognosis of the patient,complications as well as hospital infection,surgeries,gender of the patients constituted major factors on inpatient medical expenditure.Conclusions Reducing the average days of stay,guiding reasonable applications of drugs and medical materials,strengthening management on operations and controlling excessive medical services are effective approaches to reducing excessive growth of medical costs.

Objective To compare the concordance of five automated 25OHD immunoassays with liquid chromatography tandem mass spectrometry method ( LC-MS/MS) .Methods During May to July in 2014, 245 clinical serum samples that requested 25OHD tests were selected, with a total 25OHD range of 2.8 ng/ml-64.0 ng/ml, in which 154 samples did not contain 25OHD2 and 91 samples contains both 25OHD2 and 25OHD3 .To used a LC-MS/MS method that built in our laboratory to measure 25OHD, five commercial automated chemiluminescent immunoassays from Abbott Diagnostics ( A ) , DiaSorin LIASON (B), IDS-iSYS(C), Roche Diagnostics(D), and Siemens ADVIA Centaur(E).Taking the reference method LC-MS/MS as a standard , to compared the concordance and performance of the five automated 25OHD immunoassays.And used the commonly accepted cutoffs for 25OHDdeficiency (<20 ng/ml), and insufficiency ( 20 -30 ng/ml ) , and sufficiency (≥30 ng/ml ) to compare the uniformity of different methods .Statistical analysiswere performed by MedCalc software , Passing & Bablok regression , Bland &Altaman plots and Box and whisker plots were performed to compare the differences of the methods .Results The medium ( range:2.5% -97.5%) 25OHD of the 245 serum samples of the six methods was 23.5 (5.8-44.2) ng/ml(LC-MS/MS),20.6 (7.1-43.5)ng/ml(A),19.0 (5.4-38.0) ng/mL (B),23.0 (10.0-38.1) ng/ml(C),20.1 (5.1 -46.0) ng/ml (D),31.3 (12.3 -71.1) ng/ml (E), respectively .Passing and Bablok regression showed that method B had the best correlation coefficient with LC-MS/MS (r=0.894), while methods A, C and D had relatively small bias compared withLC-MS/MS and method E had the large bias .If the serum samples did not contain 25OHD2 , all the five automated immunoassays correlated well with LC-MS/MS with a correlation coefficient higher than 0.84, and B has the best correlation with LC-MS/MS ( r=0.930 ) .While all the correlation coefficient between immunoassays and LC-MS/MS decreasedwhen analyzing the samplescontaining 25OHD2.Using the clinical cutoffs, A, B, C, D and E had a concordance of 68.6%, 64.9%, 67.8%, 70.6% and 51.8% compared with LC-MS/MS, respectively .Conclusions There are significant differences between different detection systems of 25OHD.All the immunoassays results were affected by the existence of 25OHD2 .The concordance of serum 25OHD resultswas poor between different methods , and it may be necessary to built exclusive cutoffs for different methods.

[Objective]To discuss the characteristics of the edition and the process of collection of Xinkan Huimin Yuyao Yuanfang(referred to as the Seikado Edition),now collected in Seikado Bunko,and to analyze its research value.[Methods]Through the method of documentary research,this paper provided an overview of the book formation and the current status of the editions of Yuyao Yuanfang,focusing on the edition characteristics of the Seikado Edition,the process of collection and its research value.[Results]The Seikado Edition is the only one published in the Yuan Dynasty,with a high quality of engraving.The earliest known collector of this book should be the Qing dynasty collector ZHANG Jinwu,and then in turn through WANG Shizhong,CAI Tingxiang and CAI Tingzhen brothers,LU Xinyuan collected in order,and finally traveled to Japan,received by Japanese Seikado Bunko.In addition,by comparing the other two editions of the Yuyao Yuanfang,it was found that the Seikado Edition had more detailed records of some prescriptions and more accurate records of some drugs dosages.This indicates that the Seikado Edition has certain literary and clinical research value.[Conclusion]The Seikado Edition is a rare version that has been treasured by several famous collectors.Its content is different from the other two editions previously seen in China,and is worth further in-depth study.

Objective To analyze the vitamin D status among apparently healthy younger and elder adults in Beijing based on liquid chromatography tandem mass spectrometry.Methods This is an observational study.Participants included 287 apparently healthy young adults(143 males and 144 females) with an average of (32.2 ± 6.9) years old (19-44 years).At the same time 198 middle-and elder-aged adults were recruited [90 males,108 females,(55.6 ± 7.6) years],and fasting blood samples were collected and serum were isolated.They measured 25-hydroxyvitamin D (25OHD:25OHD2 and 25OHD3)using liquid chromatography tandem mass spectrometry method.Vitamin D with deficiency,insufficiency,sufficiency and intoxication was categorized as 25OHD ＜ 20 ng/ml,20-30 ng/ml,30-150 ng/ml,and ≥ 150 ng/ml,respectively.ALT,Ca,P,Cr,Glu,TG,TC and iPTH wereanalyzed using automatic analyzers.Statistical analysis was performed using SPSS17.0.Results The median 25OHD level in the total studied younger adults was 16.0 [2.5％-97.5％:(6.1-29.0) ng/ml] which didn't show significant difference with that of middle-and elder-aged adults.Younger males had significant higher level of 25OHD than females [17.9 (8.3-32.3) ng/ml vs.14.4 (5.4-26.4) ng/ml,Z =-4.238,P ＜ 0.01].Of the total younger subjects,the rate of vitamin D with deficiency (＜ 20 ng/ml),insufficiency (20-30 ng/ml)and sufficiency (≥30 ng/ml) was 72.8％,25.1％,2.1％,respectively,while that of middle-and elderaged adults was 76.3％,21.2％,2.5％ respectively,and that of younger males was 65.0％,30.8％,4.2％,respectively while that of younger females was 80.6％,19.4％,0％,respectively.Younger females had significantly higher rate of 25OHD deficiency (x2 =31.766,P ＜ 0.01).With adjusting sex,age and BMI,serum iPTH (r =-0.264,P ＜ 0.01) was significantly negatively correlated with 25OHD while Cr (r =0.221,P ＜ 0.01) showed significantly positively correlation with 25OHD.Conclusion Vitamin D deficiency is prevalent in both younger and elder adults in Beijing,especially in younger females.

OBJECTIVETo explore the correlation between cytogenetic findings and clinical manifestations of Turner syndrome.

METHODS607 cases of cytogenetically diagnosed Turner syndrome, including those with a major manifestation of Turner syndrome, were analyzed with conventional G-banding. Correlation between the karyotypes and clinical features were analyzed.

RESULTSAmong the 607 cases, there were 154 cases with monosomy X (25.37%). Mosaicism monosomy X was found in 240 patients (39.54%), which included 194 (80.83%) with a low proportion of 45,X (3 ≤ the number of 45, X ≤5, while the normal cells ≥ 30). Structural X chromosome abnormalities were found in 173 patients (28.50%). A supernumerary marker chromosome was found in 40 cases (6.59%). Most patients with typical manifestations of Turner syndrome were under 11 years of age and whose karyotypes were mainly 45,X. The karyotype of patients between 11 and 18 years old was mainly 45,X, 46,X,i(X)(q10) and mos45,X/46,X,i(X)(q10), which all had primary amenorrhea in addition to the typical clinical manifestations. The karyotype of patients over 18 years of age were mainly mosaicism with a low proportion of 45,X, whom all had primary infertility. 53 patients had a history of pregnancy, which included 48 with non-structural abnormalities of X chromosome and 5 with abnormal structure of X chromosome.

CONCLUSIONGenerally, the higher proportion of cells with an abnormal karyotype, the more severe were the clinical symptoms and the earlier clinical recognition. Karyotyping analysis can provide guidance for the early diagnosis of Turner syndrome, especially those with a low proportion of 45,X.
