Chinese Pharmacological Bulletin 2014;(7):889-892,893
AIDS has become a global disease,and a variety of drugs are used in the treatment of AIDS ,but the interindividual variabilities in efficacy and toxicity remain important limitations for the use of these drugs.Studies have shown genetic polymor-phism is the main reason for interindividual variabilities of drug reaction.In recent years,scholars focused on the pharmacog-enomics of anti-AIDS drugs and found that genetic polymor-phisms,in large part,determine the interindividual variabilities of the responese of these drugs.This paper reviews the research progress on pharmacogenomics of the four types of anti-AIDS drugs commonly used in China,including nucleoside reverse transcriptase inhibitors (NRTIs),non-nucleoside reverse tran-scriptase inhibitors (NNRTIs),protease inhibitors (PIs)and integrase inhibitors (raltegravir).

Objective To determine the relationship between serum adiponectin level and chronic inflammation,atherosclerosis in maintenance hemodialysis(MHD)patients.Methods Totally 60 MHD patients and 30 healthy volunteers were included in this study.Serum adiponectin level(ADPN)and C-reative protein(CRP),interleukin-6(IL-6)were measured.Carotid initial-medial thickness(IMT)and brachial arterial vasodilation were determined by echocardiography.Results Serum ADPN level(0.99?0.37)was higher in MHD patients than that(0.39?0.14)in controls.The ADPN level of higher IMT group was lower than that in normal IMT group.CRP,IL-6 and Cartid IMT were negatively correlated with ADPN(r=-0.22,-0.31-0.26,P

Objective To explore the application of integrating 64-slice CT image with three-dimensional electroanatomic mapping(Carto-Merge) in guiding catheter ablation of atrial fibrillation(AF).Methods Fifteen patients with drug-refractory AF received catheter ablation of AF.64-slice CT scan was performee 1-3 days prior to the ablation procedures.Using a novel software package,the left atrium(LA)with PVs was segmented and extracted for image registration with a combination of landmark registration and surface registration.Results The integration of the CT image into the electroanatomic mapping system was performed successfully in all patients with an error of 2.11?0.82 mm.Thirty pairs of PVs were electrically isolated after circumferential rediogrequency pulmorary rein ablation.The mean procedure time was 170.51?38.47 minutes.Cardiac tamponade occurred in one patient.All the fifteen patients were free of AF recurrence after 3 months of follow up including the 2 cases of persistent AF who required antiarrhythmic drugs.No thromboembolic events or stenosis were observed.Conclusion Integration of 64-slice CT image into the CARTO system successfully performed in patients undergoing catheter ablation of AF and enhance the ablation success rate.

Objective To conclude the practical nursing experiences of the infantile actue necrotizing fasciitis treated with vacuum sealing drainage(VSD) and continuous irrigation.Methods 21 cases of the infantile actue necrotizing fasciitis treated with with VSD and continuous irrigation were reviewed from January 2009 to December 2014.The nursing experiences of observation for the state of the illness,the safety management of VSD,the management of medication,mental nursing and health education were summarized.Results 21 infants all recovered and were discharged.Postoperative follow up 6 months later were conducted.No obvious disabilities of the extremities were found.Among them,8 cases were treated with VSD and continuous irrigation for 2 weeks and then had routine wound dressing changing for 10 days,the wound almost healed when discharged.13 cases were treated with VSD and continuous irrigation for one week and then had routine dressing changing for 12 to 13 days.The wound healed when discharged.No skin necrotizing,no scar of the incision and no other complications were detected.Conclusions Using VSD and continuous irrigation to treat the actue necrotizing fasciitis in infants are of great significance for the nurses to reduce the postoperative complication and promote rehabilitation doing as follows:turning over with the postoperative nursing of VSD in a standard manner,observation and management of the incision area,maintenance of the irrigation and VSD;observation and assessment of the infant's condition,management of the medication,mental nursing and health education.

Licorice root has been frequently used as antitode in traditional Chinese medicine. As the main active component of Licorice root, glycyrrhetic acid (GA) is mainly metabolized in liver. This study was designed to investigate the in vitro metabolism of GA by human liver microsomes (HLM) and human recombinant cytochrome P450 (CYP) isoforms. The results indicated that GA was metabolized mainly by CYP3A4. The K(m), V(max) and CL(int) of GA in HLM were 18.6 micromol x L(-1), 4.4 nmol x mg(-1) (protein) x min(-1) and 0.237 mL x mg(-1) (protein) x min(-1), respectively. At concentration up to 50 micromol x L(-1), GA inhibited CYP2C19, CYP2C9 and CYP3A4 enzyme activities with the inhibitory potencies up to 50%.

Objective Todeterminethecorrelationbetweenthrombomodulinand atherosclerosis in chronic kidney diseases (CKD) patients.Methods A total of 96 CKD patients in our hospital were enrolled in the study, including 32 maintenance hemodialysis(MHD) patients and 64 non-hemodialysis CKD patients with stage 2 to 5(non-HD) and 30 age- and gendermatched healthy volunteers were used as control.Intima-media thickness(IMT) and atherosclerotic plaquesof theextracranialcommoncarotidarteryweredetectedbyhigh-resolutionB-mode ultrasonography. Bloodlevelof thrombomodulinwasmeasuredusingELISA,andcreatinine,triglycerides, cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol were measured routinely as well.Correlation analysis of thrombomodulin with other parameters was performed.Results The thrombomodulin level was significantly higher in CKD patients as compared to healthy controls[(12.15±3.04) mg/L vs(3.12±0.23) mg/L, P<0.05], and also significantly higher in MHD patients as compared to non-HD patients [(16.89±3.35) mg/L vs (9.78±2.49) mg/L, P<0.05].The atherosclerotic plaques incidence and IMT value of carotid artery increased significantly in CKD patients compared with healthy volunteers.Thrombomodulin was positively correlated with IMT in CKD patients(r=0.335, P<0.01).Multiple stepwise regression analysis showed that thrombomodulin, Tm (OR=1.13, 95%CI 1.010-1.121), SBP (OR=1.09, 95%GI 1.009-1.114), CRP(OR=1.22, 95%CI 1.216-2.007), and Scr were independent risk factors of IMT.ConclusionThrombomodulin is correlated with carotid atherosclerosis in CKD patients and may be used as a marker to evaluate the endothelial damage.
