Objective To observe the traditional Chinese medicine (TCM) and umbilical treatment on diarrhea-predominant irritable bowel syndrome(IBS-D)with mental disorders. Methods Thirty-seven cases with IBS-D were randomized into a treatment group(33 cases) and a control group(31 cases). The treatment group was given Shugan-Jianpi TCM decoction and pepper umbilical dressing. The control group was given Pinaverium Bromide Tablets and Flupentixol and Melitracen tablets. After having been treated for 4 weeks, Hamilton Anxiety Scale(HAMA), Hamilton Depression Scale(HAMD), IBS Symptom Severity Scale(IBS-SSS), IBS quality of life questionnaire (IBS-QOL) were determined. Results After the treatment, HAMD, HAMA, IBS-SSS in the treatment group and the control group all significantly decreased (the treatment group t=14.280, 13.530, 18.847,the control group t=11.514, 9.424, 13.829, P<0.01), and IBS-QOL increased markedly(t=-16.848, -11.712, P<0.01). Compared with HAMA, IBS-SSS and IBS-QOL in treatment group, the control group showed statistical difference(t=-3.183, -2.549, 3.904, P<0.01 or 0.05). The total effective rate of the treatment group was 94%higher than 75%of the control group(χ2=4.727, P<0.05). Conclusion Shugan-Jianpi TCM decoction and pepper umbilical dressing can improve the clinical symptoms and psychological symptoms and improve the quality of life of IBS-D patients.

OBJECTIVE:To explore the correlation between ornidazole (ONZ) salivary concentration and plasma concentra-tions in healthy subjects,and to provide reference for clinical therapeutic drug monitoring. METHODS:24 healthy volunteers were selected. After oral administration of ONZ capsules 1.00 g,their venous blood and saliva were collected at 0.25,0.5,1.5,5.5, 10.5,24.5 and 43.5 h after medication. HPLC method was used to determine the plasma and salivary concentrations of ONZ. The correlation between the two was analyzed. RESULTS:The peak values of plasma and salivary ONZ concentrations appeared imme-diately at 1.5 h after administration and the peak values were(0.96±0.15)μg/ml and(0.93±0.15)μg/ml;salivary concentration of ONZ was lower than plasma concentration at each time points,but there was no statistical significance (P>0.05);the regres-sion equation of salivary ONZ concentration and plasma concentration was csaliva=1.176 5cplasma-0.199 4(r=0.990 1). The ratio of salivary concentration and plasma concentration of ONZ (S/P) was (0.91 ± 0.06),showing positive correlation (r=0.632-0.970, P<0.05). CONCLUSIONS:The salivary ONZ concentration is significantly correlated with plasma concentration in healthy peo-ple,so saliva can be used for therapeutic drug monitoring.

Objective To assess the relationship of CYP2C19 gene polymorphism with clopidogrel respon-siveness and the level of EETs in patients with ACS. Methods A total of 123 patients with ACS receiving aspirin combined with clopidogrel dual antiplatelet were enrolled. According to the results of CYP2C19 genotype,patients were divided into three groups:fast metabolic type ,medium metabolic type ,and slow metabolism type. The concentration of EETs and PAIR were compared between three groups. Logistic analysis was used to analyze the risk factors of LCR. Results There were differences statistically in level of EETs and PAIR among the three groups(P<0.05). Logistic analysis showed that the slow metabolism of CYP2C19 gene and lower EETs level were risk factors for LCR. The area under the ROC curve was 0.893(P < 0.05)by EETs level to predict the CYP2C19 genotype. Conclusion The slow metabolism of CYP2C19 gene was an independent risk factor for LCR,while the increase of plasma EETs level was a protective factor.

Obgective To investigate the impact of different ways and doses of recombinant human interferon o1b(rhIFN-α1b) on antiviral effect on respiratory syncytial virus(RSV)-effected mice and signal pathway of JAK/ STAT.Methods Forty-eight mice were divided randomly into 6 groups,negative control group,RSV-infection model group,12.5,25.0,50.0 μg rhIFN-α1 b atomization inhalation of intervention group,and 12.5 μg rhIFN-α 1 b injection of intervention group.After continuous drug therapy for 5 days,the left lung tissues of mice were aseptically dissected in the sixth day.Then it were observed lung tissue pathology changes by optical microscope,and expression of STAT1 and STAT2 protein with laser scanning confocal microscopy.Results It was observed that RSV-infection model mice's lungs had significant inflammatory injury under light microscope.After treatments of rhIFN-α 1b,it showed that the mice lung tissue had recovery of inflammation on different degrees.The group of inhaled rhIFN-o1b 50.0 μg was damaged on lightest degree.There were statistically significant differences between each group (all P ＜ 0.05).The expression of STAT1 and STAT2 protein in RSV-infection model mice's lungs decreased remarkably under fluorescene microscopy.Treatments of rhIFN-α 1b increased the expression of STAT1 and STAT2 inhibited by RSV-infection.The expression of STAT1 and STAT2 protein of the inhaled rhIFN-α1b 50.0 μg group increased significantly.The differences between groups were statistically significant(all P ＜ 0.05).Conclusions rhIFN-α 1 b played an important role in anti-RSV effects,simultaneously,it could improve the activity of JAK/STAT signal pathway inhibited by RSV-infection.The treatment effect of rhIFN-α 1b deliveried by atomization inhalation was better than that of intraperitoneal injection.And curative effect is proportional to the atomization inhalation dose within a certain range.
