Chinese Journal of Interventional Cardiology 2003;0(05):-
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.

AIM: To observe the effect of compound clindamycin liniment on acne vulgaris. METHODS: A multi-centre, open-label trial of compound clindamycin liniment in treating acne vulgaris. One hundred and fifty-three patients used compound clindamycin liniment on face three times per day for 4 wk. RESULTS: The total excellent response rate was 83.0%. The total effect rate on pustule and papule was 96.1% and 80.7% respectively. The adverse reaction rate was 1.9%. CONCLUSION: Compound clindamycin liniment is an effective and safe drug in the treatment of acne vulgaris.

Objective To explore conduct disorder tendency and it's influence factors on secondary school students. Methods 669 students of grade 1 in Dezhou Vocational and Technical College were investigated by Conduct Disorder Tendency Questionnaire, Revised Version of MBI-SS and SRHMS Version1.0. Results The secondary vocational school students' scores on violation tendency, addiction tendency and aggression tendency were 11.51±4.08,5.90±2.68 and 6.68±2.63,and were significant different from vocational college students or high school students(addiction tendency:F(2, 1578)=7.48,P =0.001;aggression tendency:F(2, 1579)=24.40,P <0.001). There existed great capable difference of conduct disorder according to genders ( t(643)>3.85,P <0.001).Conduct disorder tendency of secondary vocational students' was positive correlated with their learning burnout (Pearson correlation coefficient was between 0.16 and 0.52 for each pair), but negative correlated with mental health(Pearson correlation coefficient was between -0.13 and -0.27 for each pair). The linear regression showed that some dimensions of learning burnout and self-rated mental health predicted students' conduct disorder tendency. Conclusion Conduct disorder tendency of secondary vocational students is affected by their learning burnout and mental health.

Mantle cell lymphoma (MCL) is a group of highly aggressive non-Hodgkin lymphoma (NHL) in small B-cell lymphoma, accounting for 6 % of NHL incidence. MCL is characterized with its concealed onset, strong aggression, high malignancy and poor prognosis. Therefore, more attention should be paid to the diagnosis and differential diagnosis of MCL in clinic. Recently, diagnostic models of molecular pathology, researches on cyclin D1 protein negative MCL, staging prognosis and stratification treatment of MCL are worthy of attention.

Objective To investigate the relationship between serum levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMP) and the mortality in patients with malignant middle cerebral artery infarction.Methods A total of 74 patients with malignant middle cerebral artery infarction (MMCAI) was assigned to research group,74 healthy volunteers were recruited to serve as healthy controls,and 242 patients with other cerebral infarction were recruited to serve as case controls.Quality-of-life questionnaire and clinical examination were used to collect the information of participants.Endpoint was 30-day mortality.Results The research group showed higher serum levels of MMP-9,MMP-10,and TIMP-1 relative to the case control group,and the case control group showed higher serum levels of MMP-9,MMP-10,and TIMP-1 relative to the healthy control group (P < 0.05).Compared to survivor ones,non-surviving MMCAI patients showed lower Glasgow Coma Scale score (P < 0.05),higher serum levels of tumor necrosis factorα (TNF-α),MMP-9,MMP-10,and TIMP-1 (P < 0.05).Multiple logistic regression analysis showed that serum levels of TNF-α,MMP-9,MMP-10,and TIMP-1 were associated with 30-day mortality,and the OR were 1.09,1.18,1.13,and 1.32,respectively.Conclusions Serum levels of MMP-9,MMP-10,and TIMP-1 levels in MMCAI patients were associated with mortality,and could be used as an auxiliary index of mortality in MMCAI patients.
