Objective:To explore the diagnostic value of color Doppler echocardiography for cardiac tumors .Meth-ods:Clinical data of 87 patients with cardiac tumors were retrospectively analyzed ,including their diseased loca-tion ,clinical manif′estations and echocardiography feature .Results:All cardiac tumors obtain pathologic confirma-tion .There were 73 patients (83.9% ) with benign cardiac tumors ,including 66 patients (90.4% ) with myxoma and seven patients with other types ;there were 14 patients (16.1% ) with malignant cardiac tumors .Echocardiography indicated that myxoma was often located in left atrium (n=58) ,most cases possessed pedicell,its activity was large ;Other type benign cardiac tumors feature :The 6 case (86% ) were generated inside cardiac muscle without pedicell, its echo was more strong ;malignant tumors:its attachment surface was wide without pedicell,and it may show with globular or cauliflower ,and accompanied hydropericardium mostly .Conclusion:Echocardiography can dynamically observe the form ,size ,echo and hemodynamic changes of tumors ,its diagnostic accuracy is high .Myxoma is most frequent cardiac tumor .

Objective To investigate the effectiveness of background music in operating room on psychology of patients and medical personnels. Methods A total of 127 patients who would receive selective operation and 65 surgical staff in our hospital were randomly divided into the intervention group and the control group. There were 63 patients and 30 medical personnel in the intervention group, 64 patients and 35 medical personnel in the control group. Routine care was given to all patients, and background music was broadcasted after patients and medical personnels coming into operating room in the intervention group. The blood pressure and heart rate of patients were contrasted, and the anxiety status was evaluated by Self-Rating Anxiety Scales (SAS), Visual Analogue Scale was used to appraise the horror, discomfort and pain between the control group and the intervention group. Results Diastolic pressure and systolic pressure was higher and heart rate was more rapid in the control group than in the intervention group. SAS score of patients and medical personnel was higher in the control group than in the intervention groups, degree of horror, pain and complaint in patients was more apparent in the control group than in the intervention group. Conclusions Background music could release negative emotion and was helpful for stabling the mood of medical personnel and preserving physical and mental health of patients.

The labeled compounds, CdTe was combined with anti-fluoranthene antibody, had good dispersion and stability with the fluorescence intensity enhancing. A direct competitive fluorescent immunoassay with CdTe-anti-fluoranthene antibody to detect fluoranthene in water sample in the environment was developed. The result showed that fluoranthene can be determined in the concentration range from 0.1 μg/L to 1000 μg/L with a correlation coefficient of 0.9983, a sensitivity of (IC_(50)) of 12.4 μg/L and a detection limit (IC_(20)) of 13.1 ng/L. Trace environmental pollutant in environmental water samples were successfully determined with a good accuracy and suitability. The recovery was between 95.1% and 111.0%, with relative standard deviation less than 9%.

Objective To clarify the relation between the expression of Foxp3 in peripheral blood and plasma transforming growth factor betal (TGF-β1) and the activity of systemic lupus erythematosus (SLE). Methods Foxp3 mRNA expression of 28 active SLE patients, 13 inactive SLE patients and 16 healthy controls was determined by polymerase chain reaction. Active SLE patients were followed up; Foxp3 mRNA expression of 20 active patients was measured in the stable status and the plasma TGF-β1 was measured by ELISA in the active and stable status. Results The active SLE patients showed reduced levels of Foxp3 mRNA than the inactive SLE patients (P<0.01) and the healthy controls(P<0.01). Expression of Foxp3 mRNA and the plasma level of TGF-β1 in 20 SLE patients were both higher in stable status than in active status, Conclusion The expressions of Foxp3 mRNA in peripheral blood and TGF-β1 in plasma has significant inverse corelation with disease activity, which suggests that regulatory T cells may play an important role in the pathogenesis of SLE.

The exploration of drug toxicity and mechanisms is a vital component in ensuring the safe use of drugs in clinical practice, as this topic has attracted widespread concern. The intestinal flora holds great significance for drug metabolism, efficacy and mechanism, and is an instrumental metabolic organ that facilitates material information transfer and biotransformation. However, an increasing number of studies have shown that intestinal bacteria are closely related to the toxicity of specific drugs. On the one hand, drugs are transformed into toxic metabolites under the influence of intestinal bacteria, thus inducing direct drug toxicity. On the other hand, the composition and function of the intestinal flora are altered under drug influence, resulting in disruption of endogenous metabolic pathways. Consequently, this disruption compromises the intestinal barrier and affects other organs, leading to indirect drug toxicity. This review meticulously compiles recent examples of drug toxicity attributed to intestinal bacteria, explores in depth the contention that metabolic enzymes of gut microbiota may be of great influence on oral drug toxicity, and outlines prospective avenues for future research on gut microbiota and drug toxicity and mechanisms. This not only provides novel perspectives for the judicious clinical utilization of drugs but also offers insights for the safety assessment of innovative pharmaceuticals.

AIM:To investigate the effect of insulin on vascular smooth muscle cells (VSMCs) proliferation and to evaluate the intracellular signaling pathways involved.METHODS:VSMCs separated from Sprague-Dawley rats were used in this study. The proliferation of VSMCs induced by insulin was assayed by [3H]-thymidin incorporation. The protein expression and activity of p-ERK1/2 were determined by immunblot and [?-32P]ATP incorporation.RESULTS:Insulin induced cell proliferation in a concentration-dependent manner. The proliferative effect of insulin on VSMCs was inhibited partly by LY294002 (48.8%),an inhibitor of PI-3 kinase,and the ERK1/2 inhibitor PD98059 (43.6%),respectively. Moreover,phosphorylation of ERK1/2 and activity of ERK1/2 induced by insulin were also inhibited partly by LY294002.CONCLUSION:PI-3 kinase and ERK1/2 are involved in insulin induced VSMCs proliferation.

Several kinds of column chromatography method were used to investigate the chemical constituents of the leaves of Lophatherum gracile. The structures of the isolated compounds were identified based on their physicochemical properties and spectral data. A new flavone C-glycoside was isolated and its structure was identified as 3'-methoxyl-luteolin 6-C-beta-D-galactopyranosiduronic acid (1 --> 2) -alpha-L-arabinopyranoside (1).
