Objective To investigate change of chemokine mRNA and protein in the patients with diabetes mellitus(DM)complicated infection.Methods Fourty-eight patients with DM complicated infection were studied.Expression of mRNA and protein of monocyte chemoattractant protein-1(MCP-1)and interleukin 8 (IL-8)were measured by FQ-PCR,RT-PCR and ELISA.The relationship between hs-CRP,PMNL,IL-8 and MCP-1 were analyzed.Results Expression of mRNA and protein of MCP-1 and IL-8 were increased in the DM patients complicated infection.MCP-1 mRNA(mesured by FQ-PCR)was positively correlated with the protein(IL-8 r = 0.33;MCP-1 r = 0.88;P

Objective To determine the significance of change of insulin-like growth factor-1(IGF-1) and study the effect of IGF-1 on expression of Bcl-2 and Bax.Methods Male Balb/c mice were randomly divided into control group,coxsackie B3(CVB3) infection group(infection group),CVB3 infection with IGF-1 treated group.Animals were killed at d7,d14.The immunohistochemical studies and medical imagine analysis system were performed to evaluate the expression of Bcl-2 and Bax in myocardial tissue.Serum IGF-1 concentrations were assayed by radioimmunoassay(RIA).Results In infection group,the concentrations of IGF-1 were more decreased than that of control group and the expression of Bcl-2 reduced and Bax increased(P

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 clinical application of free superficial iliac circumflex artery skin flaps, as well as the management of donor site defects.

METHODS17 free superficial iliac circumflex artery skin flaps were applied for the traumatic defects or deformities on face, neck, foot, hand, ankle and lower leg, respectively. The donor site defects were closed directly or covered by paraumbilical island flaps.

RESULTSThe 17 flap size ranged from 5 cm x 3 cm to 19 cm x 14 cm. 16 flaps survived completely except 1 flap with partial necrosis, which was closed by free skin graft. The donor site defects were closed directly in 10 cases, and covered by paraumbilical island flaps in 7 flaps without no flap necrosis. The abdomen had a good appearance.

CONCLUSIONSGood appearance can be achieved with free superficial iliac circumflex artery skin flaps for the defects on face, neck, foot, hand, ankle and lower leg. Paraumbilical island flap can be used for the donor site defects.

Plant samples were collected and investigated periodically. According to the growth of different parts and the characteristics of dry substance accumulation of Scrophularia ningpoensis, the development of S. ningpoensis could be divided into four stages: seeding stage, stem and leaf growth stage, expanding period of root tubers, and dry substance accumulation stage of root tuber. Leaf numbers of S. ningpoensis grew gradually from one at first to 370 at the final stage, main stem leaf were 50 pieces. Leaf size increasesed with the fastest growth at the stem and leaf growth stage, average daily increase amount was 225 cm2. By the middle of August, leaf size reached to 16,270 cm2. Leaf area indexrose sharply in the seeding stage, and remained above 8 among stem and leaf growth stage and expanding period of root tubers, and rapidly reduced to zero in the stage of dry substance accumulation of root tuber. Leaf area ratio has a tendency of obvious dropping. The net assimilation rate had a small change ranges, two small peak were seeding stage and dry substance accumulation of root tuber. The value of specific leaf area was higher in seeding stage, and in the earlier stage of dry substance accumulation of root tuber. Relative growth rate changed with large ranges, higher in seeding stage, rapid decrease in stem and leaf growth stage, rose in expanding period of root tubers, and declined again in the stage of dry substance accumulation of root tuber. Crop growth rate was higher in the first and last stages, and smaller in interim stage. The growth parameters of S. ningpoensis such as relative growth rate, net assimilation rate, leaf area index, leaf area ratio, specific leaf area, crop growth rate changed along with the growth. The rule of dry matter accumulation was as follows: the dry matter increased slowly during the seeding stage and speeded up in the middle and late stages, and in dry substance accumulation of root tuber increased slower, the growth of dry matter all appeared an "S" curve, and accorded with logistic equation. Cultivation technologies of S. ningpoensis and the relevant management methods could be established according to the growth of different parts of S. ningpoensis and the characteristics of dry substance accumulation in different stage.
