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.

Objective:To evaluate the bond strength of root canal sealer AH Plus and GuttaFlow to root canal walls after final rinse with 4 different final irrigation regimens.Methods:60 teeth with single-canal were prepared chemomechanically using 5.25% sodi-um hypochlorite (NaOCl)as root canal irrigant.The teeth were then randomly distributed into 3 groups(n =20)according to the final irrigation protocol:1 7% EDTA followed by 2% chlorhexidine(CHX)(group 1 ),5.25% NaOCl followed by 1 7% EDTA(group 2), 0.9% normal saline(NS)(group 3).The root canals were then filled with sealers using a lentulo spiral and each group was distribu-ted into 2 subgroups according to the sealers(n =1 0):a.AH Plus;b.GuttaFlow.The roots were transversally sectioned to obtain 2mm thick dentinal slices.Then a push-out bond strength test was carried out and failure mode was observed by stereomicroscope. Results:The bond strength of AH Plus was significantly higher than that of GuttaFlow(P <0.05)regardless of the final irrigation reg-imens.When the root canals were filled with AH Plus,the push-out bond strength of group 1 (5.37 ±2.80)MPa was significantly lower than group 2(8.81 ±4.38)MPa and group 3(9.07 ±2.77)MPa(between group 1 and 2 or 3,P <0.05;between group 2 and 3,P >0.05).When the root canals were filled with GuttaFlow,the push-out strength of group 1 ,2 and 3 was (1 .40 ±0.59)MPa, (1 .26 ±0.62)MPa and (1 .05 ±0.27)MPa respectively(P >0.05).The failure modes of AH Plus and GuttaFlow were both mainly mixed,but the proportion of adhesive failure in the canals filled with GuttaFlow were obviously higher than AH Plus.Conclusion:The bond strength to root canal wall of GuttaFlow is significantly lower than that of AH Plus.1 7% EDTA followed by 2% CHX as fi-nal irrigant can reduce the bond strength of AH Plus but has no marked effect on GuttaFlow.

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.

AlM:To compare the efficacy and safety of latanoprost and brimonidine in the treatment of open angle glaucoma, and provide reference for rational drug use.METHODS:A total of 121 cases ( 136 eyes ) who were diagnosed as primary open angle glaucoma were selected in this study, and they were randomly divided into experimental group (62 cases, 70 eyes) and control group ( 59 cases, 66 eyes) according to different drug treatment. Patients in the control group received brimonidine eye drops twice a day, while patients in the experimental group received latanoprost eye drops once a day. The intraocular pressure, visual acuity and adverse reactions were checked of the two groups in the following 3mo.RESULTS:The intraocular pressure of patients in the control group was 18. 1 ± 1. 3mmHg, while the experimental group was 17. 0 ± 0. 9mmHg after 12wk of treatment, which were both lower than before (P<0. 05). The fluctuation of intraocular pressure in the experimental group was significantly lower than that of the control group. There was no significant difference in the LogMAR visual acuity between before and after treatment in the control group, while the LogMAR visual acuity of the experimental group was significantly improved. The control group had hyperemia, burning sensation, tearing, eyelid edema and other adverse side effects, and the experimental group had little adverse reactions. CONCLUSlON: Latanoprost can significantly reduce intraocular pressure in glaucoma patients with in the follow- up time, and reduce the impact of elevated intraocular pressure in the vision of glaucoma patients, with little adverse reaction, worthy of clinical application.

Objective To evaluate the bond strength of GuttaFlow sealers to root canal walls after final rinse with two novel fi nal irrigation regimens, QMiX and 17%EDTA+0.2%Cetrimide (CTR). Methods Thirty single-canal teeth were prepared chemomechanically using 5.25% sodium hypochlorite (NaOCl) as root canal irrigants. The teeth were then randomly distributed into three groups(n=10)according to the final irrigation protocol:QMiX group,17% EDTA followed by CTR group and control group(normal saline,NS).After the filling with GuttaFlow using a lentulo spiral,the roots were transversally sectioned to obtain 2 mm thick dentinal slices.Then a push-out bond strength test was carried out,and failure mode was determined at×24 magnification.Results The push-out bond strength was significantly higher in QMiX group than that of EDTA+CTR group and NS group(P<0.05),and no significant difference was observed between EDTA+CTR and NS groups(P>0.05).The failure patterns were mainly mixed.Conclusion The QMiX,as the final irrigant,can improve the bond strength of silicone-based sealer GuttaFlow.

Objective To explore the relationship between free fatty acid(FFA)composition and other glucose and lipid metabolic parameters in patients with metabolic syndrome(MS)in community. Methods Serum FFA profile was measured with gas chromatography and mass spectrometry in 158 patients with varied metabolic syndrome components(MSC),including 61 with MS and 97 at high-risk for MS,and 43 control subjects,with diagnostic criteria by the International Diabetes Federation(IDF).Results Patients with MS had higher parameters of polyunsaturated fatty acid(PUFA)and n6PUFA,as compared to the patients at high risk and normal subjects(P0.05). Among the high-risk group,those with diabetes had increased linoleic acid,n6PUFA and total fatty acid (TFA),and decreased saturated fatty acid(SFA)/TFA,as compared to those without diabetes(P

Objective To explore the role of CD3 +CD8 +T cells in children with severe bacterial meningitis at early stage by studying the changes of CD3 +CD8 +T cells and its relationships with markers of inflammation and humoral immunity. Methods Thirty-nine cases aged ≤14 years old were enrolled in this retrospective study,who were admitted in our PICU from Aug 1. 2014 to Dec 31. 2015 with diagnosis of se-vere bacterial meningitis. The patients were divided into 2 groups according to the changes of CD3 +CD8 + T cells:group A:normal or elevated(≥190/mm3,n=22),group B:decreased( <190/mm3,n=17). Distribu-tion and differences of biomarkers of inflammation,humoral immunity and changes in cerebrospinal fluid be-tween the two groups were analyzed. Results The ratio of CD3 + CD8 + T cells were decreased in 17 (43. 6%)cases. Though there was no statisticly significant difference,the percentile of patients in group B (58. 8%) with Glasgow coma score lower than 8 was higher than that in group A(31. 8%). All the four death were in group B. The mean values of C-reactive protein and procalcitonin were 251. 0(26. 2,417. 0) mg/L,32. 7(0. 9,100. 0) ng/L in group B,which were higher than those in group A[106. 5(12. 0,458. 0) mg/L,4. 5(0. 1,200. 0)ng/L],respectively(P<0. 05). Six cases(35. 3%) in group B with WBC<4 × 109/L was more than 1 case(4. 6%) in group A,and 12 cases(70. 6%) in group B with ratio of neutrophils>80% was more than 7 cases(31. 8%) in group A,there were significant differences(P<0. 05). Fourteen cases(82. 3%) with glucose concentration lower than 2. 0 mmol/L in group B was more than 11 cases (50. 0%) in group A,the difference was significant(P<0. 05). Conclusion CD3 +CD8 +T cells might be suppressed in children with severe bacterial meningitis at early stage,and might associate to the damaging de-gree of brain,inflammation reaction and prognosis in those patients,which should be helpful in using of im-mune regulators for children with severe bacterial meningitis.
