OBJECTIVE: To establish an HPLC method for the content determination of prostaglandin A1 and prostaglandin B1 in Alprostadil for injection.METHODS: The determination was performed on Alltech Alltima C18 column with mobile phase consisted of phosphate puffer(pH=6.3)-acetonitrile-methanol(70 ∶ 25 ∶ 5) at a flow rate of 1.5 mL? min-1.The detection wavelength was set at 196 nm.The column temperature was set at room temperature and the injection volume was 20 ?L.RESULTS: The prostaglandin A1 and prostaglandin B1 were well separated from main component and other impurities.The linear range of prostaglandin A1 and prostaglandin B1 were 0.175～19.00 ?g?mL-1(r=0.999 7) and 0.23～19.90 ?g?mL-1(r=0.999 2).The contents of prostaglandin A1 in 3 batches of samples were 4.7%,4.9% and 4.3%,and the contents of prostaglandin B1 in 3 batches of samples were 0.6%,0.8% and 0.5% respectively.CONCLUSIONS: This method is proved to be simple,specific and suitable for the content determination of related substances in Alprostadil for injection.

Objective To verify the validity and feasibility of national early warning score (NEWS) in evaluation of death risk in elderly patients with critical illness,in order to find out which scoring method is more suitable for elderly critical illness patients.Methods A prospective case-control study was conducted.The critical illness patients aged over 60 years old with the length of hospital stay over 24 hours,and admitted to Department of Emergency of Qingdao Municipal Hospital from January to December 2015 were enrolled.The clinical data including in emergency and the actual outcome of patients were collected,and the patients were divided into death group and survival group according to 30-day outcome.Patients in the two groups were assessed by using NEWS and risk classification according to the first results of vital signs monitoring.Multivariate logistic regression model was used to analyze the relationship between the NEWS classification and the risk of death in elderly critical ill patients.Results 1 950 emergency elderly patients with critical illness were enrolled,with 78 cases (4.0％) dead within 30 days and 1 872 survived (96.0％).Compared with the survival group,patients in death group were older (years:79.8 ± 10.8 vs.75.3 ± 8.9,t =4.335,P ＜0.001),and had higher acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score (22.9± 4.6 vs.18.2 ± 4.8,t =8.487,P ＜ 0.001),lower Glasgow coma scale (GCS) score (12.2 ± 4.5 vs.13.4 ± 5.2,t =-2.007,P =0.045),higher incidence of respiratory system diseases (29.5％ vs.17.9％,x 2 =12.742,P =0.013),higher NEWS score (11.2 ± 5.5 vs.3.9 ± 2.7,t =22.063,P ＜ 0.001),as well as higher proportion of patients with NEWS classification of high risk and very high risk (65.4％ vs.15.8％,x 2 =263.125,P ＜ 0.001).With the increase of NEWS risk classification,mortality rate was also increased,and the mortality rate in the patients with low,medium,high and very high risk were 0.81％ (9/1 108),3.63％ (18/496),5.83％ (13/223),30.89％ (38/123),respectively,with statistically significant difference (x 2 =179.741,P ＜ 0.001).It was showed by logistic regression analysis that the NEWS score of elderly patients with critical illness were positively correlated with 30-day death.The 30-day death risk of patients with middle risk,high risk and very high risk was 4.600,9.052 and 54.598 folds of the patients with low risk respectively.Conclusion NEWS score can be used to assess the risk of death in emergency elderly patients with critical illness.NEWS risk classification can quantify and classify the risk of death in the elderly patients with critical illness.

Objective To evaluate the characters of respiratory function in children with chronic cough and explore the correlative association between cough variant asthma(CVA) and etiology of chronic cough.Methods One hundred and forty patients with chronic cough were divided into 2 groups based on peak expiratory flow(PEF) or forced expiratory volume in one second(FEV1).Ninty-three cases were done exercise test and 47 cases were done bronchoditor rest.The parameters included forced vital capacity(FVC),FEV1,PEF,forced expiratory flow at 50% and 75%(FEF50,FEF75).Results The measurement 35 cases with positive bronchoditor rest,and 30 cases with positive exercise test were found.The PEF and FEV1 variation rate were(18.30?10.50)%,(18.78?9.44)% in exercise test groups,and(30.36?27.27)%,(36.13?26.83)% in bronchoditor rest groups,respectively.Conclusions FEV1,PEF may be used as markers for the reversibility of airway obstructe in children with CVA.There is significant correlation between PEF and FEV1.Respiratory function mensurate may reflect the change and degree of inflammation in the airway of children with chronic cough.

AlM: To study an approach to visual acuity correction after intracapsular cataract extraction by phase - ll intraocular lens implantation through the individualized arcuate keratotomy.
METHODS: For demonstration, 48 postoperative patients ( 50 eyes ) receiving the intracapsular cataract extraction were gathered up. Each patient received a scleral tunnel major incision along the radial line of the maximum corneal refractive power determined by a cornea curvimeter, and a arcuate keratotomy was made opposite to the major one; through the major incision an iris-claw intraocular lens is implanted. Each patient was measured for their corneal astigmatism and uncorrected visual acuity before and after the surgery.
RESULTS: The results suggested the average corneal astigmatism before the surgery and that 3d, 1, 3, 6 and 12mo after the surgery as+3. 18±0. 68,-1. 56±0. 73,+0. 87± 0. 51, + 1. 21 ± 0. 70, + 1. 33 ± 0. 68 and + 1. 48 ± 0. 48 respectively. The uncorrected visual acuities 3d, 1, 3, 6 and 12mo after the surgery are 0. 5±0. 38, 0. 56±0. 23, 0. 55± 0. 24, 0. 52±0. 28 and 0. 51±0. 25 respectively.
CONCLUSlON: Phase-ll intraocular lens implantation witharcuate keratotomy is helpful to improve the postoperative visual acuity and reduce preoperative corneal astigmatism after the intracapsular cataract extraction aphakic eyes, lt is also a low-cost surgery, and easy to perform, with minor surgical injuries, particularly available for surgical visual acuity correction of the aphakic eye receiving intracapsular cataract extraction.

Objective To explore the immunogenicity of recombinant chimeric 6Aβ15-T including the Aβ1-15 epitope and a T-helper epitope formulated with different adjuvants and to evaluate its feasibility as a candidate vaccine for Alzheimer disease (AD).Methods The recombinant chimeric antigen 6Aβ15-T formulated with Al adjuvant, Freund′s adjuvant or MF59 adjuvant was administered to two strains of mice .The 6Aβ15-T-immunized group without adjuvants ( Mock) and non-immunized group (Control) were included in this study as control groups .The specific antibody and cellular immune response of the chimeric antigen were evaluated .Results In BALB/c strain mice, three types of adjuvants could substan-tially boost the immunogenicity of chimeric antigen 6Aβ15-T and produce a high level of specific-Aβ(β-amyloid) antibod-ies.In C57BL/6 strain mice, the existence of adjuvants enhanced the immune response of 6Aβ15-T antigen, but the mice in Mock group also produced a strong antibody response .In two strains of mice, prevalence of anti-AβIgG1, which was an indicator of Th2 polarization, was observed in the 6Aβ15-T-immunized mice.Additionally, the Al adjuvant induced a high-er level of IgG1 antibody titers, and the ratio of IgG1/IgG2a was the largest.As expected, the 6Aβ15-T antigen formulated with or without adjuvants induced PADRE-specific, but not Aβ42-specific T cellular immune response .Conclusion The 6Aβ15-T antigens formulated with different types of adjuvants could induce strong Th 2-polarized Aβ42-specific antibody re-sponses without activating self-reactive Aβ42-specific T cells in two strains of mice .The results suggested that the recombi-nant chimeric antigen 6Aβ15-T is a good candidate vaccine for AD .
