Objective To evaluate the prognosis capacity of the Primary Angioplasty in Myocardial Infarction (PAMI) risk score for 6 months mortality in the clinical patients with ST segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PCI), in addition to asses the incremental value of EF and multivessel disease for risk stratification. Methods Six clinical variables and their relative value of score derived from PAMI risk scoring system were used to determine individual's risk score. The patients with STEMI were evaluated during the in-hospital period and followed-up for a mean of (10.34?3.24) months for mortality. The p values were calculated using a Kruskal-Wallis H test for categorical variables when appropriate; otherwise Independent-samples test was used. Logistic regression examined the discriminant accuracy of the PAMI risk score to predict death and assessed the incremental value of the EF and multivessel disease. Results A 88.8% of patients (183 patients) finished the follow up of 6 months. The overall in-hospital mortality rate was 4.4%, 30-day mortality rate was 6% and 6 months mortality rate was 9.3%. Eighty-eight patients scored 0-2 points, 54 patients scored 3-5 points, 17 patients scored 6-8 points and 24 patients scored ≥9 points. The 6 months mortality were 1.1%,3.7%, 17.6% and 41.7% respectively. Logistic regression analysis indicated that multivessel disease is a risk factor (OR 10.189) and EF is a protected factor (OR 0.849) for 6 months mortality after PCI. Multivessel disease and EF provided incremental information over that provided by the PAMI risk score. Conclusion The PAMI risk score can be applied in early stage after PCI for mortality risk assessment for patients with STEMI. EF and multivessel disease also convey important prognostic information and should be included in risk stratification after STEMI.

[ABSTRACT]OBJECTIVE To summarize the clinical related factors and prognostic influence factors of perioperative pulmonary embolism of head and neck malignant tumor.METHODSFrom 2010-2014, our hospital carried out a total of 2736 cases of head and neck malignant tumor surgical operations, of which, 10 cases were clinically diagnosed as postoperative pulmonary embolism, retrospectively analyzed the process of clinical treatment of the patients of pulmonary embolism with head and neck malignant tumors, and summarized their etiological factors, clinical manifestations, diagnosis and treatment. RESULTS The preoperative period incidence of pulmonary embolism in patients with head and neck malignant tumor was 0.37%(10/2736). Their clinical manifestations were mainly of asthma and breathing difficulty, and 3 cases of asymptomatic hypoxemia. 8 cases of patients showed pulmonary artery and branch filling defects after pulmonary artery angiography (CTA), 7 cases of patients got cured and were discharged from the hospital after comprehensive treatment such as anticoagulation etc; 3 cases of patients died after emergency treatment. 2 cases of patients suffered cavity bleeding, and there was no anticoagulant drug adjustment.CONCLUSIONThe mortality of head and neck cancer patients with perioperative pulmonary embolism is high, and therefore, preventive measures and timely treatments are important to reduce the incidence of pulmonary embolism.

Objective: To investigate the effect of abstracted formula granule of Siwu drugs on the sex hormones and expressions of androgen receptor (AR)and estrogen receptor (ER) in bone marrow depressed mice. Methods: One hundred and eighty mice (90 male and 90 female) were randomly divided into 6 groups. The effects of the formula granule of Siwu on sex hormones and expressions of AR and ER were explored by SABC method in bone marrow of depressed mice. Results: For the male rats, the levels of androgen were increased in male of treatment groups compared with those of model groups (P＜0.05), and the levels of estrogen were decreased in male of treatment groups compared with those of model groups (P＜0.05).For the female rats, the levels of androgen were increased in female of treatment groups compared with those of model groups,but no significant differences (P＞0.05), and the levels of estrogen were decreased in femal of treatment groups compared with those of model groups (P＜0.05). There was a dose dependent manner between treatment groups. Conclusion: The results suggested that formula granule of Siwu drugs may play a role in the hematopoietic function to repair bone marrow depression by improving AR and the balance of estrogen / androgen in mice.

Objective To investigate clinical characteristics and risk factors in elderly patients with type 2 diabetes mellitus (T2DM) complicated with chronic kidney disease (CKD).Methods Two hundred and two T2DM patients aged ≥60 y admitted in Tongren Hospital from August 2009 to February 2012 were enrolled in the study,including 64 cases complicated with CKD (CKD group)and 138 cases without CKD (non-CKD group).Hemoglobin (Hgb),albumin (ALB),glycated hemoglobin A1C (HbA1 c),fasting plasma glucose(FBG),postprandial glucose (PBG),serum creatinine (Scr),blood urea nitrogen (BUN),uric acid (UA),total cholesterol (TC),triglyceride (TG),high densitylipoprotein (HDL-C),low density lipoprotein (LDL-C) were measured and ratio of urinary albumin to creatinine (UAER/CR) were calculated,ankle brachial index (ABI) and ambulatory blood pressure was examined.Results The duration of diabetes in CKD group was longer than that in non-CKD group [(13 ± 11) vs.(10 ± 7) y,t =2.35,P ＜ 0.05].Hgb and ALB in CKD group were lower than those in non-CKD group [(12.1 ± 1.7) vs.(13.3 ±1.3) g/L,(34.4±2.6) vs.(36.8 ±3.4) g/L,t=-5.73,-4.75,allP＜0.01]; UA,TG,24 h systolic blood pressure (SBP),24 h pulse pressure (PP)in CKD group were higher than those in non-CKD group [(367 ± 81) vs.(323 ± 74) μmol/L,(1.6 ± 0.9) vs.(1.3 ± 0.7) mmol/L,(133 ± 14) vs.(127±16)mmHg,(65 ±12) vs.(58 ±12)mmHg,t =3.82,2.50,2.47,3.68,all P＜0.1].The UAER/CR in CKD group and non-CKD group was 86.2 mg/g (24.6-374.8 mg/g) and 6.0 mg/g (3.6-17.8 mg/g),respectively (P ＜ 0.01) and ABI in CKD group and non-CKD group was 0.94 ± 0.18 and 1.03 ±0.18 (-2.78,P ＜0.05).There were no significant differences in FBG,PBG,HbA1c,TC,HDL-C andLDL-C between two groups(t =-2.02,1.47,1.48,-0.53,-1.20,-0.76,all P＞0.05).Logistic regression analysis showed that ALB,TG and UAER/CR were the independent risk factors of CKD in T2DM patients(OR:0.79,3.63 and 1.04,95％ CI:0.62-1.01,1.45-9.01 and 1.00-1.08).Spearman correlation analysis demonstrated that eGFR was positively associated with Hgb,ALB,ABI (r =0.38,0.33 and 0.28,all P ＜ 0.01),negatively associated with age,BUN,Cr,UA,TG,UAER/CR,24 hSBP and PP in all diabetes patients(r =-0.32,-0.63,-0.89,-0.34,-0.18,-0.65,-0.16 and -0.248,all P ＜0.01).Conclusions ALB,TG,UAER/CR are the independent risk factors of chronic kidney disease in elderly patients with type 2 diabetes mellitus.

Objective To identify the potential DNA vaccine candidate which can induce the protective immune response to Toxoplasma gondii by inoculating mice with plasmid DNAs encoding three different forms of P30 antigen (membranous secretory,and intracellular). Methods Three forms of recombinant plasmid: pcDNA3 P30Mb(contain the whole P30 gene sequence,including the gene encoding signal peptide and hydrophobic tail),pcDNA3 P30Se(contain the whole P30 gene sequence, without the gene encoding hydrophobic tail) and pcDNA3 P30In(contain the whole P30 gene sequence,without the gene encoding signal peptide) were constructed by PCR and subcloning technique. The mice were immunized with different forms of recombinant plasmids and IgG antibodies in the mice were detected by ELISA and Western blotting. Results Three forms of expression recombinant plasmid of Toxoplasma gondii P30 gene were successfully constructed. The P30 inserts were identified by restrictive enzyme digestion and sequencing. ELISA and Western blotting analysis demonstrated that specific IgG antibody could be induced in three immunized groups, but there was some difference in appearence time and intensity of IgG.Conclusion Genetically immunization of mice with the recombinant plasmids could elicit specific IgG antibodies. In respect to IgG response, the immune efficiency of the three forms of recombinant plasmids was different at the beginning (2 wk),but 4 wk later approximately same.
