During primary percutaneous coronary intervention(PCI), a concurrent chronic total occlusion(CTO) is found in 12%-13% of patients with ST-elevation myocardial infarction(STEMI). Long-term benefits of CTO-PCI have been suggested; however, when is the best opportunity to take PCI for CTO is lacking. Our aim was to disscuss the best time for CTO-PCI with STEMI.

OBJECTIVETo study clinical outcomes of Chinese medidine fumigation and massage therapy for the treatment of knee stability and functional recovery after anterior cruciate ligament reconstruction operation,and to explore the effect on tendon-bone healing.

METHODSTotal 50 patients were divided into two groups: the control group (normal rehabilitation therapy group),the treatment group (Chinese medicine fumigation and manipulation group). There were 25 patients in the control group, including 16 males and 9 females, who were treated with isometric muscle training, with the gradually enlarging amplitude of flexion and progressive loading of bearing training for knee recovery. There were 25 patients in the treatment group, including 15 males and 10 females,who were treated with the conventional rehabilitation therapy combined with Chinese medicine fumigation and massage therapy. The Chinese herbs named as Haitongpi decoction was steamed by a special equipment to fumigate the knee after operation; Based on the biomechanical parameters of the ligament reconstruction, the massage therapy was designed to control the degree of the knee flexion and release the adhesion for early recovery of knee functions. The Lysholm knee function evaluation system was used, and MRI examination was performed to measure the change in width of ligament tunnel in femur and tibia to evaluate the safety and stability of the treatment.

RESULTSLysholm system showed that two groups both had improving results from the 1st month after operation to the 3rd month (treatment group, F=36.54, P<0.05; the control group, F=28.12, P<0.05), and the results of the treatment group was better than that of the control group at the observation point (the 1st month, t=0.105, P<0.05; the 3rd month, t=5.361, P<0.01). There was no difference between the two groups when evaluating the bone and tendon healing 3 and 12 months after operation (P>0.05), indicating that Chinese rehabilitation therapy was a safety treatment without the influence on the loosing of tendon.

CONCLUSIONChinese medicine fumigation and massage therapy can early improve the knee function after the anterior cruciate ligament reconstruction operation without the disturbance of the knee stability.

Objective To asess the primary percutaneous coronary intervention(PPCI) strategies of culprit vessel with two lesions in ST-segment elevation myocardial infarction(STEMI) patients and their prognosis.Methods The study retrospectively reviewed 418 patients with STEMI undergoing PPCI in the General Hospital of Shenyang Military Region from January 1st to June 30th in 2015 and 75 patients were included. According to whether the non-infarct-related lesions(N-IRL) being treated or not,the patients were identified as both IRL and N-IRL being treated(the research group,n=33) or the culprit lesion(or infarct-related lesion,IRL) being treated only(control group,n=42). The endpoint was major adverse cardiocascular event(MACE) which was a composite of death from cardiac causes,nonfatal myocardial infarction,target vessel revascularization(TVR) and hospitalization with angina or heart failure.Results The study endpoint betwwen the two groups showed no statistical differences in MACE(P=0.446). Multivariate Cox regression analysis showed that age, diameter of N-IRL were predictive factors of MACE. When N-IRL located beyond the culprit lesion, the research group showed higher risk of MACE(P=0.022) and TVR(P=0.039).Conclusions The non-infarct-related lesions of patients with STEMI undergoing PPCI may be left for conventional medical treatment. It may be reasonable to choose drug therapy for distal N-IRL and to choose PCI for proximal N-IRL.

UNLABELLEDProminent eosinophil airway inflammation is important in the pathogenesis of asthma. There is increasing evidence that the disorder of eosinophil apoptosis contributes to the mechanism. But most of the studies have been done in vitro or on animal models, very few were done among the adult asthmatics in vivo.

OBJECTIVEThe aim of this study was to elucidate the relationship between the apoptotic eosinophils and Bcl-2 in asthmatic children in vivo.

METHODSEleven mild to moderate asthmatic patients were recruited and the range of age was 7 - 14 years (9 males, 2 females), meanwhile 7 patients with lower respiratory infection were recruited as control and the range of age was 9 - 14 years (5 males, 2 females). Before and after inhaled glucocorticoid (GC) induced sputum, bronchoalveolar lavage (BAL), bronchial mucosa specimens and peripheral blood were obtained for measuring and comparing the changes of apoptotic EG(2)(+) cell by combining the techniques of TUNEL and immunohistochemistry, meanwhile the expression of Bcl-2 in bronchial mucosa specimens was measured by using the immunohistochemical assay.

RESULTSBefore the inhalation of GC, the apoptotic EG(2)(+) cells in asthmatics were significantly lower than that in control group (P < 0.01), and the numbers of EG(2)(+) cell in asthmatics group were significantly higher than that in control group (P < 0.001). After the treatment apoptotic EG(2)(+) cells in asthmatics were increased (P < 0.01), and the numbers of EG(2)(+)cell were decreased (P < 0.01, P < 0.05 and P < 0.05, respectively), FEV(1)% was increased (P < 0.05). Before the inhalation of GC, the numbers of Bcl-2(+) cell in asthmatic airway submucosa were higher than that in control group (P < 0.05) but after the treatment the number of Bcl-2(+) cell did not change significantly. (4) Before and after GC treatment the percentages of apoptotic eosinophils of peripheral blood in vivo had no significant changes compared with those of control subjects (P > 0.05). There was a positive correlation between apoptosis of EG(2)(+) cell in sputum, BAL, airway submucosa and FEV(1)% (P < 0.05).

CONCLUSIONApoptosis of EG(2)(+) cell decreased in the airway of asthmatic children and inducing EOS apoptosis is one of the important mechanism of inhaled GC therapy for asthma.

BACKGROUNDSome larger scale, randomized studies have demonstrated the superiority of drug-eluting stents (DES) over bare metal stents (BMS) for the treatment of acute myocardial infarction (AMI). This study aimed to investigate the impact of DES, in comparison with BMS, on the 2-year clinical outcomes in patients with ST-elevation myocardial infarction (STEMI).

METHODSFrom January 2002 to December 2008, a total of 1301 consecutive STEMI patients treated with coronary stenting in Shenyang Northern Hospital were prospectively registered. Patients received BMS (n = 868) or DES (n = 435) implantation in the infarction related artery according to physician's discretion. A propensity score analysis was performed and two well matched subgroups were selected (BMS, n = 288; DES, n = 288) to evaluate the 2-year clinical outcomes. The primary outcome was the occurrence of major adverse cardiac events (MACE), which was defined as a composite of all-cause death, myocardial infarction (MI), or target vessel revascularization (TVR).

RESULTSSurvival salvage analysis showed that 2-year cumulative hazards were not significantly different between the two groups with respect to TVR (2.8% vs. 3.1%, log-rank P = 0.780), stent thrombosis (1.7% vs. 4.2%, log-rank P = 0.079) and MACE (8% vs. 10.8%, log-rank P = 0.236). Multivariate analysis showed that DES was an independent protective factor of MI (HR: 0.211, 95%CI: 0.049 to 0.908) and stent thrombosis (HR: 0.327, 95%CI: 0.107 to 0.994).

CONCLUSIONDES was associated with similar 2-year clinical outcomes to those of BMS for the treatment of STEMI in daily practice.

objective To explore the impact ot ideal health behaviors and health tactors on the detection rate of the carotid plaques.Methods Subjects with previous stroke,TIA,myocardial infarction were excluded from the study.A total of 5852 employees (active and retired employers from Tangshan Kailuan company) aged 40 years and over were included through stratified random sampling.Information was obtained from the unified questionnaire,measurements of blood biochemistry and carotid artery ultrasonography.Results (1) The carotid artery plaque detection rates were 67.0％,52.3％,50.5％,44.3％,37.2％,31.9％,26.1％ and 4.2％ in the groups with0,1,2,3,4,5,6 and 7 components of ideal cardiovascular health behaviors and health factors,respectively.(2) The carotid artery plaques total burden score [TBS:M (Q1,Q3)] were7(7,7),7(5,7),7(5,7),5(3,5),5(3,5),5(3,5),3(3,3),3(3,3) in the groups with 0,1,2,3,4,5,6 and 7 components of ideal cardiovascular health behaviors and health factors,respectively.(3) Multiple logistic regression analysis showed that 3,4,5 and greater than 5 components of ideal cardiovascular health behaviors and health factors were protective factors against carotid plaques compared to less than 2 components of ideal cardiovascular health behaviors and factors (all P ＜ 0.05),the OR (95％ CI) values were 0.78 (0.62-0.98),0.53 (0.62-0.98),0.52 (0.39-0.71) and 0.40 (0.25-0.64),respectively.Conclusion Increasing ideal cardiovascular health behaviors and factors are negatively linked with the detection rate and TBS of the carotid plaques.

The fusion between liposome-liposome, liposome-biomembarnes induced by acid-sensitive polymers has been systematically investigated. The polymer-liposomes were constructed by post-insertion method with the poly (2-ethylacrylic acid) (PEAA) alkylamide derivatives. The liposomal fusion was studied by use of fluorescence resonance energy transfer assay, particle size, fluorescent-photometer. The results indicated that the poly (2-ethylacrylic acid)-liposomes has very strong acidic induced fusion capability. Under acidic conditions, acid-sensitive polymer liposomes fused each other, the fusion closely related to the molecular weight of acid sensitivity polymer on the surface of liposomes. The acidic fusion of polymer-liposomes was dependent upon the lipids composition, the degree of fusion was reversely related to the cholesterol contents. Acid-en ci-nsitive polymer liposomes fused with erythrocyte ghosts. The liposomal fusion induced by acid-sensitive polymer associated with the increase of membrane permeability. The good acid-sensitivity of PEAA has been further demonstrated by membrane fusion in current experiments, and the liposomes prepared with lipid anchored-poly (2-ethylacrylic acid) were developeds s a potential pH sensitive delivery system.

OBJECTIVETo explore the clinical features and prognosis of early-onset preeclampsia.

METHODSA total of 115 cases of early-onset preeclampsia were recruited from January 1999 to December 2004 and the data analyzed in terms of the incidence, manifestation, maternal and fetal complications.

RESULTThe early-onset preeclampsia accounted for 13.4% of all preeclampsia diagnosed. The perinatal mortality was 13.3% in early-onset preeclampsia. Dysfunction and hepatic dysfunction were the main maternal complications. The gestational ages at admission and at delivery were significantly correlated with perinatal prognosis (P<0.001). Most cases received regular treatment had good prognosis.

CONCLUSIONEarly-onset preeclampsia is a severe type of preeclampsia.

OBJECTIVETo explore the role of macrophage colony-stimulating factor (MCSF) in the pathogenesis of preeclampsia.

METHODSBy ELISA method, MCSF concentrations were determined in serum samples obtained from 39 patients with preeclampsia and 40 normal pregnant women as controls. The concentrations of serum MCSF were compared between preeclampsia and normal pregnancy, and between early-onset and late-onset preeclampsia.

RESULTSerum MCSF concentrations were significantly higher in preeclamptic women than those in controls (431.0 kIU compared with 179.1 kIU, P<0.001). There were no significant differences in serum MCSF levels between early-onset and late-onset preeclampsia (P>0.05). Serum MCSF was not correlated with maternal age, gestational age, and placenta weight (P>0.05 for all).

CONCLUSIONIncreased level of serum MCSF is an important indicator of preeclampsia and it may play a role in the pathogenesis of the disease.
