Objective: To observe the effects of neuromuscular blockade after combining atracurium (ATC) with veeuronium (VEC). Method: Fifty-four patients undergoing elective abdominal surgery(ASA grade Ⅰ-Ⅱ) were allocated randomly into 3 groups. After induction with intravenous midazolam-etomidate-fentanyl, neuromuscular blockade was measured with the train of four (TOF) to the ulnar nerve by monitoring the contraction of musculus adductor pollicis. The onset time and the peak effect were observed. According to the dose-effect relationships of the combination of ATC and VEC and that of either ATC or VEC given alone,the ED_(50) and ED_(95) were caeulated. The isogram and algebraic methods were used to analyse interaction between them. Result: The fraction ED_(50) values of ATC and VEC in combination were 52.26 and 11.71?g/kg respectively, The algebraic subtotal of combinations was 0.75

Objective This paper aims to assess the clinical efficacy of pemetrexed maintenance therapy in patients with advanced non-small cell lung cancer( NSCLC) through Meta analysis.Me thods Systematic lit-erature searches were performed in Cochrane、Pubmed,Web of science, Embase and ClinicalTrials databases.The related references had been traced.We made quality assessment of qualified randomized controlled trials( RCTs) of pemetrexed maintenance therapy compared with best supportive care( BSC) in advanced NSCLC.Besides,we u-tilized stata 12.0,Revman 5.3 and GRADEpro software to evaluate the overall quality of the evidence,according to the Cochrane collaboration to perform Meta-analysis.Resutl s Three RCTs were eligible and included 1257 patients.Meta-analysis results suggested that:compared to BSC,pemetrexed maintenance therapy had a statisti-cally significant benefit in improving progression-free survival(PFS)(HR =0.55,95% CI:0.48~0.64)and overall survival(HR=0.76,95%CI:0.65~0.88).The objective response(ORR)did not reach statistical signif-icance(RR=0.97,95%CI:0.86~1.10).Conclusion Compared with BSC,pemetrexed maintenance therapy statistically significantly improve PFS and OS,but has no demonstrable impact on ORR in patients with advanced NSCLC.

Objective To investigate the training of recruits′psychological stress and its relevant influencing factors ,so as to of‐fer scientific basis for the psychological training and psychological health education of recruits .Methods Questionnaire survey method was used and a total of 720 training of recruits in 2013 was sampled .The application of the stress response questionnaire (SRQ) ,eysenck personality questionnaire (EPQ) ,trait coping style questionnaire (TCSQ) ,symptom checklist (SCL‐90) were used to carry out the psychological test and analysis on these recruits .Results The total score of the SCL‐90 and the score of each factor were significantly lower than the norm of recruits in year of 2000(P<0 .01) .Compared with the norm of SCL‐90 of Chinese sol‐diers in 2004 ,the factor score of somatization ,anxiety and terror were significantly higher than those of domestic soldiers .However , the factor score of hostility and bigotry were significantly lower than those of domestic soldiers (P<0 .05) .The new soldiers who were the only child of the family and was born with urban registered permanent residence had more obvious psychological stress symptoms .The total score of psychological stress and each factor score of new soldiers with different educational level had no sig‐nificant difference (P>0 .05) .According to what was shown in the related analysis ,the SCL‐90 total score .SRQ total score had significant positive correlation with emotional stability and negative coping style(P<0 .01) ,but had significant negative correlation with introversion‐extroversion and waste score(P<0 .01) ,and the total score of SCL‐90 had significant positive correlation SRQ to‐tal score(P<0 .01) .It was shown in the regression analysis that factors had significant predictive effect on the psychological factors of new soldiers during the training period respectively were as follow :negative coping ,stability ,introversion‐extroversion ,psychoti‐cism and whether they are the only child or not .The decisive coefficient of 5 variables was R2 =0 .558 ,F=163 .65(P<0 .01) .Con‐clusion The overall mental health of 2013 recruits training are in good condition ,individual mental health status ,personality traits and coping style training of recruits psychological stress are significant predictors .

Objective To explore the efficacy and safety of sodium nilroprusside(SNP) with remifentanil or fentanyl used for controlled hypotension during the pediatric patent ductus arteriosus (PDA) operations. Methods Sixty children undergoing operation were randomly divided into SNP with fentanyl (A group) or remifentanil (B group). Hemodynamic changes in different times and adverse reactions were observed. Results In B group, heart rate was stable and blood pressure declined quickly. The dose of SNP was fewer and hemodynamic changes and recovery from anesthesia were better in B group than in A group. Conclusion Remifentanil could potentiate the hypotensive effect of SNP and decrease adverse reaction.

Objective: The bioactivity of four podophyllotoxin analogues were tested against 3rd instar larvae of Culex pipiens pallens and 5 h instar larvae of Pieris rapae L.Methods:WHO bioassay and leaf-dlpping method. Results: ①Deoxypodophyllotoxin and ?-apopicropodophyllotoxin exhibited toxicity(against) Culex pipiens pallens,and their LC_(50) were 0.001 48 and 0.001 68 g/L,respectively.②All the four podophyllotoxin analogues displayed inhibitory effect on the growth and development against Culex pipiens pallens,their pupation rates were delayed comparing with control.③Deoxypodophyllotoxin,?-apopicropodophyllotoxin and Podophyllotoxin exhibited toxicity against Pieris rapae L,the LC_(50) 96 h after treatment were 0.045 4?0.078 2 and 0.159 7 g/L,respectively.④All the four podophyllotoxin analogues showed antifeedant activity against Pieris rapae L,their AFC_(50)were 0.016 1,0.018 7,0.039 4 and(0.273 9) g /L,respectively.⑤All four podophyllotoxin analogues displayed inhibitory effect on the growth and development against Pieris rapae L,but the extent of each compound were very different. Conclusion: Based on the data obtained in this investigation,it is possible that the dissimilarity in the structure of the analogues leads to their different bioactivity.

Objective:To observe the effects of salidroside on the expression of substance P (SP)and neurokinin-1 receptor (NK-1R)of bone marrow cells(BMCs)in bone marrow(BM)depressed anemia mice,and to explore its roles for hematopoietic regulation.Methods:Automatic blood cell analysator was used to detected the changes of peripheral blood cells in each group ,immuno-histochemistry and reverse transcription-polymerase chain reaction ( RT-PCR) were used to analyze the expressions of SP and its receptor NK-1R of BMCs in each group respectively.Results: Peripheral blood testing results showed that the number of white blood cells (WBC),red blood cells(RBC)and hemoglobin(HB)of model group were significantly decreased when compared with control group.Compared with model group ,low-dose,middle-dose and high-dose salidroside obviously elevated the number of white blood cells ,and middle-dose salidroside obviously elevated the number of platelets.Immunohistochemistry studies showed that the expression of SP and its receptor NK-1R of BMCs was found in each group.Compared with control group , the expression of SP of BMCs was decreased obviously in model group(P<0.05),and the expression of NK-1R of BMCs was decreased slightly in model group (P>0.05),and the expression of SP and its receptor NK-1R of BMCs was increased significantly in low-dose,middle-dose and high-dose salidroside groups (P<0.05).RT-PCR data showed that the expression of SP mRNA of BMCs was increased obviously in model group ,low-dose,middle-dose and high-dose salidroside groups when compared with control group (P<0.05).The expression of NK-1R mRNA of BMCs was un-detected in control group and model group.The expression level of NK-1R mRNA of BMCs was elevated gradually with the increase of salidroside dosage in low-dose,middle-dose and high-dose salidroside groups.Conclusion: The mRNA and protein expressions of SP and its receptor NK-1R of BMCs were up-regulated significantly by salidroside in dose-dependent manner.These data suggest that salidroside could participate in the recovery of hematopoietic function of BM depressed anemia mice by increasing the expression of SP and its receptor NK-1R of BMCs.

A selective precolumn derivatization liquid chromatography-tandem mass spectrometric (LC-MS/MS) method for the determination of glucosamine in human plasma and urine has been developed and validated.Glucosamine was derivatized by o-phthalaldehyde/3-mercaptopropionic acid.Chromatographic separation was performed on a Phenomenex ODS column (150 mm × 4.6mm,5μm) using linear gradient elution by a mobile phase consisting of methanol (A),and an aqueous solution containing 0.2％ ammonium acetate and 0.1％ formic acid (B) at a flow rate of 1 mL/min.Tolterodine tartrate was used as the internal standard (IS).With protein precipitation by acetonitrile and then the simple one-step derivatization,a sensitive bio-assay was achieved with the lower limit of quantitation (LLOQ) as low as 12 ng/mL for plasma.The standard addition calibration curves suitable for clinical sample analysis showed good linearity over the range of 0.012-8.27 μg/mL in plasma and 1.80-84.1 μg/mL in urine.The fully validated method has been successfully applied to a pharmacokinetic study of compound glucosamine sulfate dispersible tablets in health Chinese volunteers receiving single oral doses at 500,1000 and 1500 mg of glucosamine sulfate,as well as multiple oral doses of 500 mg t.i.d.for 7 consecutive days.
