Objective To investigate the effects of atorvastutin on the levels of plasm imflammation markers (hs - CRP, MMP - 3, TNF - α) and intima - media thickness(ITM) of the common carotid artery in patient with hyperlipidemic and atherosclerosis. Methods Fifty patient with hyperlipidemic and atherosclerosis were treated with atorvastatin (10mg qd) for 12 weeks. The levels of TC, TG, LDL -C, HDL -C, hs -CRP, TNF -α and MMP -3 were detected with radioimmmuneassay and eolorimetric methods. Color Doppler echo-cardiography was used to measure intima -media thickness(ITM) of the common carotid artery after 6 weeks and 12 weeks. Results TC, TG, LDL -C, hs -CRP, TNF -α and MMP -3 were decreased significantly(P < 0.01)after 12 weeks. IMT was decreased signifi-cantly(P < 0.05) and HDL - C was increased significantly (P < 0.05) after 12 weeks. Conclusion Atorvastatin could be effective in re-ducing blood - fat and anti - inflammatory action , regulating blood vessel endothelium (BVE) function and reversing structural chan-ges in IMT of the common carotid artery.

Objective To explore the effect of the single maximum of alcohol consumption on vomiting induced by chemotherapy in male patients with nasopharyngeal carcinoma.Methods According to the single maximum of alcohol consumption,48 cases of male patients with nasopharyngeal carcinoma were divided into two groups:group A (small capacity for liquor group 10-50 g),group B (large capacity for liquor group ＞50 g).The amount of alcohol intake was assessed by a questionnaire.The responses of vomiting and the effects of antiemetic therapy between the two groups during the first cycle after induction chemotherapy were observed.Results The incidence rates of vomiting induced by chemotherapy between the two groups were 52.0％ and 17.4％,respectively.There were significant differences between the two groups (x2 =6.273,P ＜0.05).The incidence rates of grade 0,1,2 and 3 of vomiting in group A were 48.0％,20.0％,20.0％,12.0％,in group B were 82.6％,13.0％,4.4％,O,respectively.There were significant differences between the two groups (x2 =6.013,P =0.024).In the two groups,the complete control rate for acute vomit were 48.0％ and 82.6％ (x2 =6.273,P =0.012),for delayed vomit were 36.0％ and 65.2％ (x2 =4.090,P =0.043).There were also significant differences between the two groups.Conclusion With the increasing of capacity for liquor,the incidence of vomiting is significantly reduced,the degree of vomiting is distinctly alleviated,and the antiemetic efficacy is distinctly increased.

Objective To develop a method for determination of serumal copper ion in rabbit with implantation of copper intrauterine device.Methods At different time points after implantation,the serumal copper ion concentrations were determined by microwave digestion-inductively coupled plasma mass spectrometry(ICP-MS) using scandium(Sc) and indium(In) as internal standards to compensate sample matrix effects,and the pharmacokinetics parameters were calculated in order to reflect copper ion release and metabolic rule.Results The serumal copper ion concentrations were kept at a low and stable level.The recoveries were in the range of 98.7%-113.3%,with the relative standard deviations of less than 5.0%.Conclusion The analytical method is simple,fast,and can be used for the determination of serumal copper ion in rabbit.

Objective:To investigate the effect of oxycodone hydrochloride on patients with analgesic effect and immune function of intestinal tumor after operation.Methods:50 patients with intestinal tumor from June 2014 to December 2016 who were treated in our hospital were selected randomly to divide into oxycodone group and fentanyl group with 25 cases in each group.Patients in oxycodone group were given oxycodone hydrochloride intravenous injection of 5mg 15 minutes before the end of surgery;and patients in fentany group were given fentany intravenous injection of 50ug 15 minutes before the end of surgery.Visual analogue scale (VAS),ramsey sedation score were observed at 3 h (T0),6 h (T1),12 h (T2),24 h (T3) 48 h (T4) after operation,Levels of serum tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and IL-10 CD4+,CD8+,CD4+/CD8+ and NK cells measured before anesthesia,and at T2,T3,T4 respectively.Results:At time point of T1,T2,Ramsey scores of oxycodone group were significantly lower than that of fentany group (P＜0.05),At time point ofT0,T3,T4,Ramsey scores of the two groups showed no significant difference (P＞0.05).At time point of T2,T3,T4,levels of serum TNF-α,IL-6 and IL-10 of two groups of patients were significantly higher than those of anesthesia before (P＜0.05),TNF-α,IL-6 and IL-10 ofoxycodone group was significantly lower than those of fentany group (P＜0.05).At time point ofT2,T3,T4,CD4+/at CD4+ of the two groups were significantly decreased,and CD8+ was significantly increased(P＜0.05).Levels of CD4+,CD4+/CD8+ of oxycodone group was significantly higher than that of fentany group (P＜0.05),and level ofCD8+ was significantly higher than that of fentany group.At time point of T2,T3,NK cells of two groups were significantly decreased,NK cells of oxycodone group were significantly higher than that of oxycodone group (P＜0.05).Differences among postoperative nausea,vomiting,respiratory depression,dizziness,skin itching incidence of two groups of patients were not statistically significant (P＞0.05).Conclusion:Oxycodone hydrochloride has little effect on the immune function of patients with intestinal tumor,and it is suitable for Postoperative analgesia of patients with intestinal tumor.

Objectiye To measure longitudinal (T1) and transverse (T2 ) relaxation time of metabolites in m. soleus (SOL) and m. tibialis anterior TA of healthy volunteers at 3.0 T through 1H-MRS and optimize measurement protocols. Methods Altogether 24 healthy volunteers were recruited in the study. All subjects signed a letter of informed consent. After divided into 2 groups randomly by the table of random number, 1H-MRS measurements with stimulated echo acquisition mode (STEAM) sequence were undertaken in SOL and TA separately. Progressive saturation method was used for T1 measurement. Spectra with 8 different TRs (770,900,1000, 1100,1200,1500,2000 and 3000ms ) were acquired with TE=20 ms.T2 time was measured by changing TE. Altogether 8 TEs (20,30,45,60,90,135,200 and 270 ms) were used with TR = 3000 ms. Metabolites' concentration was calculated through T1 and T2 correction using water as internal reference. The t test was used for statisties. Results Altogether 22 groups of data were gained ( 12 for SOL, 10 for TA ) . T1 value of water, Creatine-CH3 ( Cr3 ), Trimethyl amonium ( TMA ),extramyocellular lipid (EMCL) and intramyocellular lipid (IMCL) in SOL were ( 1384. 0 ± 36. 9 ),( 1064. 0 ± 167.0), (964. 2 ± 144. 0 ), ( 373.0 ± 46. 8 ), ( 374. 7 ± 20. 6) ms respectively and T2 value were (26.5 ±1.2), (100.2±19.3), (149. 1 ±32.7), (81.4±5.2), (84.7±4.2) ms. InTA T1 value of water, Cr3, TMA, EMCL, and IMCL were ( 1307. 0 ± 24.4), (945.7 ± 132. 0), (968.3 ± 127. 0),(372. 7 ± 39. 2), (412. 8 ±80. 2) ms respectively and T2 value were (27. 1 ± 0. 9), (135.3 ± 18. 2 ),(62.1 ± 6. 0), ( 84. 3 ± 4. 0 ), ( 90. 7 ± 3.2 ) ms. After corrected by the calculated relaxation times, the concentrations of Cr3 in SOL and TA were (33. 1 ± 3.7) and (31.7 ± 3. 1 ) mmol/kg respectively, TMA (35.2±3.2) and (32.9 ±5.2) mmol/kg, EMCL (12.2 ±5.0) and (8.9 ±4.9) mmol/kg, IMCL (9. 0 ± 2. 4) and (3.0 ± 0. 8 ) mmoL/kg. IMCL in TA was much lower than SOL with statistical significant ( t = 8. 044, P < 0. 01 ), the difference between other metabolites were not statistically significant( t = 0. 926,1. 264, 1. 542, P > 0. 05 ) . Conclusions Accurate relaxation time was measured at 3.0 T of the metabolites in skeletal muscles of healthy adult human. After corrected by the relaxation times, the absolute concentrations calculated were consistent with the reported results. Quantitative knowledge of muscle NMR relaxation time was a prerequisite for absolute quantification of metabolites using the 1H-MRS and also was useful for optimizing measurement protocols.
