OBJECTIVETo investigate whether there is an association between DRD2/ANKK1 Taq IA polymorphism and early infant temperament.
METHODSDRD2/ANKK1 Taq IA polymorphism (rs1800497) was determined using polymerase chain reaction-ligase detection reaction (PCR-LDR) techniques in 149 Chinese Han infants from Changsha City. Their mothers were asked to complete the Early Infant Temperament Questionnaires (EITQ) when the infants were 1 to 4 months old (mean: 2.75 months). There were three genotypes found in these infants: C/C, T/T and C/T. The subjects were subdivided into T-carrier (CT, TT) and non-T-carrier (CC) groups for statistical analysis.
RESULTSThere were no differences in the temperament style distribution between the T-carrier and non-T carrier groups. There were also no statistically significant differences between the two groups in the score of the nine temperament dimensions.
CONCLUSIONSDRD2/ANKK1 Taq IA polymorphism is not associated with early infant temperament.

OBJECTIVESTo evaluate the clinical characteristics, in-hospital and three-year outcome in ST-elevation myocardial Infraction (STEMI) patients receiving conservative treatment (CT), thrombolytic treatment (TT) and primary percutaneous coronary intervention (PCI) in Beijing.
METHODSThis 12-month prospective, multicenter registry study was conducted in 19 hospitals with 808 patients with STEMI in Beijing between Jan. 2006 and Dec. 2006, 518 (64%) received PCI, 106 (16.1%) received TT and 184 (22.8%) received CT therapy. Patients were followed up for 3 years.
RESULTSAt baseline, the age of patients in CT group [(64.5 ± 13.5) years] was significantly higher than those in TT group p(57.9 ± 11.0) years] and in PCI group [ (60.4 ± 12.3) years, all P<0.01]; and the median time from symptom onset to hospital in CT group (207 min) was significantly longer than those in TT group (130 min) and PCI group (130 min, all P<0.01). Emergency Medical Service (EMS) use was significantly higher in PCI group (184/518, 35.5%) than in CT group (46/184, 27.3%) and TT group (29/107, 25.0%, all P<0.05). Health insurance holder was the highest in PCI group (P<0.01). PCI was performed less frequently than thrombolytic therapy [66.6% (345/518) vs. 80.2% (85/106)m P=0.02] during off-hours and more frequently performed in tertiary hospitals than in secondary hospitals[66.8%(437/651) vs. 52.6% (81/154, P<0.01)]. The in-hospital mortality and the cardiovascular mortality at 3 year after hospital discharge was significantly higher in CT group [9.2% (17/185) and 9.4% (15/159)] than in PCI group [3.5% (18/518), 4.5% (20/446)] and TT group [6.6% (7/106), 2.3% (2/86), all P<0.01]. Patients in PCI group had the highest adherence level of aspirin, β-blocker, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers or statins at 3-years follow-up (all P<0.05). Multivariable Cox proportional hazards regression analysis showed that only PCI was associated with lower risk of cardiovascular death (HR-0.40, 95% CI:0.21-0.73, P<0.01).
CONCLUSIONSSocial and clinical setting may affect the physician's decision to provide reperfusion therapy in Beijing for STEMI patients. Better adherence of secondary preventive drugs and lower cardiovascular death are observed in STEMI patients receiving PCI during the 3-year follow-up

Theultraperformanceliquidchromatographycoupledwithmassspectrometry(UPLC-MS)was used to investigate the metabolic difference of the decoction of Radix Aconiti Preparata ( RAP ) and its co-decoctions with Radix Paeoniae Alba ( RAP-RPA ) or Radix Stephaniae Tetrandrae ( RAP-RST ) in rat intestinal bacteria. The principal component analysis ( PCA) of the relative contents of Aconitum alkaloids after metabolism was performed by SIMCA-P software. The score plots of PCA could successfully distinguish the three groups of RAP, RAP-RPA and RAP-RST. The result indicated that the differences of biotransformation among the groups of PAP, RAP-RPA and RAP-RST were significant. With the loading plot and independent-samples T test, seven relevant markers with the significant differences were found in the group of RAP-RPA, six relevant markers were obtained in the group of RAP-RST. The relative content of four markers in RAP-RPA was higher than that in RAP, and one marker in RAP-RST was higher than that in RAP. The relative contents of other markers were all lower than that in RAP. These markers may be the effective substance for explaining the different effects of Radix Aconiti Preparata before and after combination with Radix Paeoniae Alba and Radix Stephaniae Tetrandrae.
