Objective:To analyze the feature of anaphylactic shock induced by alprostadil injection. Methods: Totally 1624 pa-tients treated with alprostadil injection in our hospital from January to March 2014 were undergone adverse drug reaction monitoring. Six cases of anaphylactic shock induced by alprostadil injection were statistically analyzed. Results:6 cases of anaphylactic shock induced by alprostadil injection occurred in the department of intervention and most of thd reaction happened in arterial injection. Two lot num-ber of drugs were in high frequency. Patients showed a sharp fall in blood pressure, chest discomfor, palpitation, shortness of breath, paleness, sweating and other symptoms. After anti allergy, blood pressure, oxygen the rapy and other treatment measures vital signs gradully stabilized. Conclusion:Anaphylactic shock induced by alprostadil injection is in correlation with the administration mode of artery injection. The change of the patient' s condition and vital signs should be closely observed when we inject the patient with alpros-tadil injection. We must prevent the occurrence of serious adverse reactions.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.

Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5％ of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P＜0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score ＞ 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P ＜ 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1％ of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2％of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

OBJECTIVE:To compare in vivo and in vitro permeation behaviors of the ethosome gels of testosterone,testoster-one propionate and testosterone undecanoate. METHODS:The ethosome gels of testosterone,testosterone propionate and testoster-one undecanoate were prepared. With cumulative permeating amount and permeation rate as the indexes,Franz diffusion cell and HPLC were employed to compare in vitro permeation behaviors of 3 kinds of ethosome gels in mouse skin. With testosterone patch as the positive control drug, electrochemistry method was adopted to detect the concentration of testosterone in plasma 0,3,6, 9,12,24,36 and 48 h after applying such 3 kinds of ethosome gels on the back of rats,and then pharmacokinetic parameters were calculated with DAS 2.0 software. RESULTS:24 h cumulative permeating amounts of the ethosome gels of testosterone,tes-tosterone propionate and testosterone undecanoate were(234.31±13.8),(175.63±41.1)and(72.60±15.3)μg/cm2,and the per-meation rates were(10.25±1.9),(7.64±1.4)and(2.96±0.8)μg/(cm2·h),respectively. The pharmacokinetic parameters of the above-mentioned three kinds of ethosome gels and the positive control drug were respectively as follows as cmax of(20.19±2.57), (17.50±2.91),(0.23±0.04),(14.97±2.12)ng/ml,t1/2Ka of(2.80±0.45),(3.36±0.59),(4.02±0.62),(4.20±0.71)h,AUC0-48 h of(13.85±1.96),(13.93±2.13),(0.35±0.07),(11.76±2.31)ng·h/ml. CONCLUSIONS:in vivo and in vitro permeation behav-iors of the ethosome gels of testosterone and testosterone propionate are fairly good.

This study was aimed to investigate the influence of TIEG1 on apoptosis of HL-60 cells and the expression of Bcl-2/Bax. Different concentration of TIEG1 were used to treat HL-60 cells, the cell growth inhibition rate was detected by MTT method. After treating HL-60 cells with 12.03 ng/ml TIEG1, cell apoptosis was detected with flow cytometry. Bcl-2 and Bax was detected with RT-PCR. The results showed that TIEG1 had inhibitory effect on HL-60 cell proliferation, and in time-and dose-dependent manners. The more obvious inhibitory effect was observed in HL-60 cells treated with TIEG1 of 12.03 ng/ml. During the course of cell apoptosis, Bax expression increased, but Bcl-2 expression decreased (P < 0.05). It is concluded that TIEG1 inhibits HL-60 cell proliferation and induces apoptosis in time and dose-dependent manners. During the course of HL-60 cells apoptosis induced by TIEG1, Bcl-2/Bax are associated with HL-60 cell apoptosis induced by TIEG1.

This study was aimed to investigate the effects of valproic acid sodium (VPA) on the proliferation and apoptosis of acute T-lymphoblastic leukemia Jurkat cells. Jurkat cells were treated with different concentration of VPA. Proliferation-inhibition curve was assayed and plotted by CCK-8 method and the cell apoptosis was detected by flow cytometry with Annexin V/PI double staining. The expression level of anti-apoptotic gene BCL-2 and pro-apoptosis gene Bak1 were detected by semi-quantitative RT-PCR. The results showed that the VPA inhibited the proliferation of Jurkat cells in concentration-dependent manner. As compared with the control group, the apoptosis of cells increased along with adding concentration of VPA; VPA could decrease the expression of BCL-2 gene, but did not show obvious effect on the expression of Bak1. It is concluded that the VPA can inhibit proliferation of Jurkat cells which possibly associates with the decrease of BCL-2 expression.

The effect of low temperature storage on dormancy breaking, sprouting and growth after planting of Tulipa edulis was studied. The results showed that starch content and activity of amylases significantly decreased during 10 weeks of cold storage, soluble protein content raised at first then decreased, and the peak appeared at the 6th week. However, total soluble sugar content which in- creased slowly at first than rose sharply and reducing sugar content increased during the storage duration. The bulbs with cold storage treatment rooted in the 6th week, which was about 2 weeks earlier than room temperature storage, but there were less new roots in the late period of storage. After stored at a low temperature, bud lengths were longer than that with room temperature treatment. Cold storage treatment could promote earlier emergence, shorten germination time, prolong growth period and improve the yield of bulb, but rarely affect the emergence rate. It was not beneficial to flowering and fruiting. The results indicated that 6-8 weeks of cold storage was deemed to be the key period of dormancy breaking preliminary.
