Objective To study the association of single nucleotide polymorphisms (SNPs) of solute carrier family 22 member 4 (SLC22A4) and SLC22A5 genes with Crhon's disease (CD) in Chinese Han nationality. Methods SNPs in the entire coding region of SLC22A4 and SLC22A5 genes were screened by direct DNA sequencing in 80 CD patients and 80 healthy subjects, and statistical in Han population. Five SNPs were found in entire coding region (2 in SLC22A4 gene and 3 in distribution of the alleles and genotypes of SLC22A4 and SLC22A5 polymorphisms between CD patients and healthy controls. Conclusion There is no correlation of SLC22A4 and SLC22A5 with CD in Chinese Han nationality.

Using a UPLC-MS/MS (MRM) and cocktail probe substrates method, the metabolic fingerprint of the compatibility of Radix Aconite (RA) and Radix Paeoniae Alba (RPA) and its effect on CYP450 enzymes were investigated. These main CYP isoforms include CYP 1A2, CYP 2C, CYP 2E1, CYP 2D and CYP 3A. Compared with the inhibition effect of RA decoctions on CYP450 isoforms, their co-decoctions of RA and RPA with different proportions can decrease RA' inhibition on CYP3A, CYP2D, CYP2C and CYP1A2, but can not reduce RA' effect on CYP2E1. The metabolic fingerprints of RA decoction and co-decoctions with different proportions of RPA in CYP450 of rat liver were analyzed by UPLC-MS. Compared with the metabolic fingerprints of RA decoction, the intensity of diester-diterpenoid aconitum alkaloids decreased significantly, while the intensity of monoester-diterpenoid alkaloids significantly increased in the metabolic fingerprints of co-decoctions of RA and RPA. The results suggest that RA coadministration with RPA increased the degradation of toxic alkaloid and show the effect of toxicity reducing and efficacy enhancing.

Objective To investigate the effects of post-operative analgesia with oxycodone or morphine for patients undergoing colon cancer radical surgery on platelet activation and cellular immunity.Methods Forty colon cancer patients scheduled for radical surgery, 23 males and 17 females, ASA physical status Ⅰ or Ⅱ, were randomly divided into 2 groups (n=20 each): oxycodone group (group O) and morphine group (group M).Patient-controlled intravenous analgesia (PCIA) was used for post-operative analgesia.PCIA solution contained oxycodone 1 mg/kg and tropisetron 6 mg in 100 ml normal saline in group O or morphine 1 mg/kg and tropisetron 6 mg in 100 ml normal saline in group M.Blood samples were obtained from the patients at 5 min before anesthesia induction (T0), 4 h after surgery (T1), 24 h after surgery (T2) and 48 h after surgery (T3).The levels of glycoprotein (GP)Ⅱb/Ⅲa, P-selection (CD62P), natural killer (NK) cells, NKT cells, and natural Treg (nTreg) cells were detected.The platelet aggregation rate (PAR) was determined.Results Compared with T0, the levers of GPⅡb/Ⅲa, CD62P, PAR and nTreg cells were significantly higher at T1 in group O and at T1, T2 in group M (P<0.05).Compared with T0, the levels of NK and NKT cells were decreased significantly at T1 in group O and at T1-T3 in group M (P<0.05).The levels of GPⅡb/Ⅲa, CD62P, PAR and nTreg cells at T2 and T3 in group O were decreased significantly as compared with group M (P<0.05).The levels of NK cells, NKT cells at T2 and T3 in group O were significantly higher than those in group M.Conclusion Post-operative analgesia with oxycodone for patients undergoing colon cancer radical surgery exhibits a more significant effect of decreasing platelets activity and presents a less disturbance on cellular immunity as compared with morphine.

The results of open-field test,step-through passive avoidance task and radial-arm maze experiment showed that changes of locomotor activity,anxiety-related behaviour and ability of learning and memory were associated with the increased apoptosis of neurons in hippocampus in rats with perinatal hypothyroidism.

Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.
