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

ObjectiveTo investigate the impact of metal plate on radiation dose distribution by Monte Carlo (MC) code. MethodsThe metal plates with 0. 4 thick were placed in water at 5 cm, all the plate irradiated with 6 MV X-ray were simulated by MC code, SSD =100 cm. The percentage depth dose with or without metal implants were compared. ResultsThe surface absorbed doses on incident plane of stainless steel plate and titanium plate were increased by 19. 6% and 15.7% respectively as compared water,the dose influence was less than 1.5% more than 0. 3 cm outside the incidence plane. The doses on the exit surface of stainless steel plate and titanium plate were lowered by 8. 6% and 8. 2% when compared with water, the dose impacts of this places where were from the exit surface of stainless steel plate 、titanium plate more than 1.2 cm,0. 9 cm were less than 1.5%. The surface absorbed doses on incident plane of stainless steel plate were increased by 3.9% respectively as titanium plate, the dose of the exit surface of stainless steel plate and titanium plate was similar. Conclusions MC method is a fast and accurate calculation method. The influence of metal plate on the radiotherapy dose distribution is significant. Under the such condition, the impact of stainless steel plate is much more than that of titanium alloy plate.

The aim of this study was to investigate the protective effect of exogenous bcl-2 on spinal cord motoneurons following sciatic nerve axotomy. After epineurium suturing, sense bcl-2 (Ad/s-bcl-2), antisense bcl-2 (Ad/as-bcl-2), or reporter gene lacZ (Ad/lacZ) recombinant adenovirus or NS was injected into the sciatic nerve 0.5 cm distant from the sutured point respectively in different groups. The rats were transcardially perfused with 4% paraformaldehyde on postoperative 48 h, 7 d, 15 d and 30 d respectively and the spinal cords of L4 to L6 were harvested. X-gal staining, bcl-2 in situ hybridization and immunohistochemical staining, TUNEL (terminal deoxynucleotidyl transferase mediated dUTP nick end labeling) staining and AChE (acetyl cholinesterase) histochemical staining were used. We observed that the exogenous lacZ gene was expressed in the spinal cord of Ad/lacZ group, and sense bcl-2 significantly decreased the number of apoptotic motoneurons and the decreasing degree of AChE activity of the motoneurons in the spinal cord induced by sciatic nerve axotomy and accelerate AChE activity recovery. However, antisense bcl-2 increased the number of apoptotic motoneurons and the decreasing degree of AChE activity of the motoneurons in the spinal cord induced by sciatic nerve axotomy and prolonged AChE activity recovery. These results demonstrate that exogenous bcl-2 may protect motor neurons from injury induced by peripheral nerve axotomy.

Male sterility affects human reproduction seriously. Modern medicine has not yet fully understood the reasons for abnormal sperm, so clinical treatment is mainly based on experience, but the effect is inaccurate. According to "kidney controls reproduction" and "chronic illness causes blood stasis" theory, Professor JIN Bao-fang treats abnormol speerm sterility by tonifying kidney and activating blood circulation to remove obstruction with modified Yangjing Decoction, which has achieved good efficacy.
