RESUMEN
Objective To observe the value of two-dimensional speckle tracking imaging(2D-STI)for evaluating right ventricular(RV)synchrony of early stage systemic lupus erythematosus(SLE).Methods Totally 60 SLE patients(SLE group)and 65 healthy subjects(control group)who underwent echocardiography were retrospectively enrolled.The general data,conventional ultrasonic parameters,strain parameters based on 2D-STI and synchrony parameters based on 2D-STI were compared between groups.Pearson correlation analysis was performed to explore the correlations of general information,conventional ultrasonic parameters and strain parameters with synchrony parameters in SLE group.Multiple linear regression was used to analyze the independent impact factors of RV synchrony of early stage SLE.Results No significant difference of general data nor conventional ultrasound parameters was found between groups(all P＞0.05).Strain parameters in SLE group were all lower,whereas synchrony parameters in SLE group were all higher than those in control group(all P＜0.05).In SLE group,synchrony parameters of RV(standard deviation of time to peak strain of global[SD-TPSglobal],of free wall[SD-TPSfree]and of interventricular septum[SD-TPSseptal])were positively and weakly correlated with both SLE duration and systemic lupus erythematosus disease activity index(SLEDAI)(| r | 0.256-0.273,all P＜0.05),but slightly and negatively correlated with global longitudinal strain(GLS)of RV(| r | 0.435-0.488,all P＜0.05).GLS of RV was the independent impact factor of synchrony parameters of early stage SLE(P＜0.05).Conclusion 2D-STI could be used to evaluate synchrony of RV in early stage SLE through measuring GLS of RV.

Objective To explore the influence of new Xuefuzhuyu decotion on IgG,C3 and C4 of peripheral blood in atherosclerosis rats.Methods Healthy adult Wister rats were selected and randomly divided into blank group,AS model group,new Xuefuzhuyu decoctioin low dosage group,the new Xuefuzhuyu decoctioin high dosage group,and positive control group,with 13 cases in each group.Vitamin D3 joint high fat feeding method was adopted to establish atherosclerosis rat model.Medicine lavage began on the first day of experiment.Low dosage new Xuefuzhuyu decoctioin,high dosage new Xuefuzhuyu decoctioin,and atovastatin were administrated to the new Xuefuzhuyu decoctioin low dosage group,the new Xuefuzhuyu decoctioin high dosage group,and positive control group respectively,and distilled water 15 ml/kg · d-1 was administrated to both the blank group and the AS model group.The weight of body was detected each week in each group for regulating the administrated dosage.After medicine lavage was performed for successive 8 weeks,blood was obtained from abdominal aorta for detecting IgG,C3,C4 by immune scattering method.Results The value of IgG,C3 and C4 were (8.110±0.720)g/L,(1.591±0.143)g/L,(0.390±0.33)g/L in the AS model group,(8.000±0.840)g/L,(1.564± 0.132) g/L,(0.396±0.36)g/L new Xuefuzhuyu decoctioin low dosage group,(7.250±0.740)g/L,(1.390±0.150)g/L,(0.326±0.153)g/L new Xuefuzhuyu decoctioin high dosage group and (7.240±0.400) g/L,(1.414 ± 0.104) g/L,(0.330±0.164) g/L in the positive control group,all of which werehigher than the blank group (5.810±0.820)g/L,(0.943±0.124)g/L,(0.330±0.164)g/L with statistically significant difference (P＜0.05).Each value of IgG,C3 and C4 in the new Xuefuzhuyu decoctioin high dosage group and the positive control group were lower than the AS model group and the new Xuefuzhuyu decoctioin low dosage group,with a statistically significant difference(P＜0.05).There was no significant difference between new Xuefuzhuyu decoctioin high dosage group and the positive control group (P＞0.05).Conclusion New Xuefuzhuyu decoction can ameliorate IgG,C3 and C4 of peripheral blood in atherosclerosis rats.Its function was similar to atorvastatin.
RESUMEN
Objective: To establish a quantitative model for evaluating the degree of traditional Chinese medicine (TCM) syndromes often seen in patients with coronary heart disease (CHD). Methods: Medical literature concerning clinical investigation of TCM syndromes of CHD was collected and organized, and the "Hall for Workshop of Metasynthetic Engineering" expert symposium method was applied. First, the 100 millimeter scaling was used for combining with scoring on degree of symptoms to establish a quantitative criterion for classification of symptom degree in CHD patients, and the model was established by using comprehensive analytic hierarchy process as the mathematical tool to estimate the weight of the criterion for evaluating qualitative syndromes in various layers by specialists. Then the model was verified in clinical practice and the outcomes were compared with fuzzy evaluation from the specialists. Results: A total of 287 clinical observation forms on CHD cases were collected, and 167 forms were available after excluding any irregular forms. The results showed that basic coincidence rate between the outcomes derived from specialists and those from the model was 68.26% (114/167), and part coincidence rate was 88.62%(148/167). Conclusion: This model, with good rationality and feasibility, has a high coincidence rate with fuzzy evaluation from specialists, and can be promoted in clinical practice. It is a good quantitative model for evaluating the degree of TCM syndromes of CHD.
RESUMEN
Objective To construct profiles of health status based upon physical,mental and social support items in adult twins of Qingdao.Methods Grade of Membership(GoM) model was applied to a set of 31 indicators to construct ideal profiles.Results Four health profiles were identified: pure type Ⅰ(healthy),pure type Ⅱ(personality disorders),pure type Ⅲ(psychological symptoms) and pure type Ⅳ(physiological symptoms).The most frequently occurring combination in this population was profile Ⅰ,Ⅱ,Ⅳ(14.74%),followed by profile Ⅰ,Ⅱ,Ⅲ,Ⅳ(13.44%),and then type Ⅰ(11.08%).Only 13.56% of subjects fell completely into one single pure type.Conclusions One healthy type and three non-healthy types are determined.Most individuals exhibit some of the characteristics of two or more types,holding partial membership in multiple categories.
