Lysimachiae Herba and Desmodii Styracifolii Herba are common traditional Chinese medicines for treating lithiasis. Both of them have efficacies of clearing heat, diuresis and eliminating calculi. However, there are some differences in their clinic applications. The former is mainly used to treat hepatolithiasis, gallstones, jaundice, stranguria and gout; Whereas the latter is mainly used to treat urinary calculus. In this paper, the pharmacological effects of Lysimachiae Herba and Desmodii Styracifolii Herba on removing calculus, choleresis, anti-inflammation and oxidation resistance were compared and analyzed based on document retrieval. In conclusion, both of them show the preventive and therapeutic effects on kidney stones and gallstones. Particularly, Desmodii Styracifolii Herba has a better effect in treating the kidney stones, while Lysimachiae Herba has a better effect in treating cholesterol gallstones.

Objective To observe the effects of one kind of angiotensin converting enzyme inhibitor (ACE1) drugs fosinopril (FOS) on transforming growth factor β1 (TGF-β1)and β1- integrin( Itg-31 ) expression in rat glomerular mesangial cells (GMC)induced by lipopolysacchatide (LPS).Methods We established the cultured glomerular mesangial cells of rat in vitro and passages 3 ~ 10 of cells were used in the experiment after identification.The experiment included the following groups:Control group,LPS induced group (LPS group) and FOS intervened group.According to the different concentrations of FOS,FOS intervened group was divided into high,middle and low dose FOS groups,which were FOS1 group,FOS2 group and FOS3 group respectively.The changes of TGF-β1 protein secretion was detected by the enzyme-linked immunosorbent-assay; The changes of TGF-β1 and Itg-β1 mRNA expression was detected by quantitative real-time RT-PCR.Results (1) TGF-β1protein secretion in rat GMC at 6h,12h,24h three time points:They were 958.55 ± 34.67 ( ng/L),1052.05 ±48.59( ng/L),1166.06 + 35.39 (ng/L) respectively in Control group.They were 1342.12 + 39.87 ( ng/L),1432.31 + 39.33 (ng/L) and 1 537.77 + 43.79 (ng/L) respectively in LPS group,which were higher significantly than those in Control group ( all P < 0.01 ).They were 779.58 ± 48.64 ( ng/L),878.33 ± 29.50 (ng/L) and 962.57 ±31.94( ng/L) in FOS1 group,989.311±73.56(ng/L),1073.29±66.89(ng/L) and 1210.75 ±61.68(ng/L) in FOS2 group,1 253.78 ±45.32( ng/L),1 348.18 ±45.81 (ng/L) and 1450.06 ±46.24( ng/L) in FOS3 group respectively,which were lower significantly in all FOS intervened groups than that in LPS group (all P<O.01).(2)TGF-β1 mRNA expressions in rat GMC at6h,12h,24h three time points were higher significantly than that in Control group.TGF-β1 mRNA expressions were lower significantly in all FOS intervened groups than that in LPS group.( 3 ) Itg-β1 mRNA expressiones in rat GMC at 6h,12h,24h three time points were higher significantly than that in Control group.Itg-β1 expressions were lower significantly in all FOS intervened groups than that in LPS group.Conclusions LPS can induce the increase of TGF-β1 secretion and mRNA expression.FOS can inhibit the TGF-β1 secrection and mRNA expession in GMC as dose-dependent manner,at the same time down regulated the Itg-β1 mRNA expression iuduced by LPS.All above supply the theoretical evidence for the renal protection of FOS by non-hemodynamics mechanism.

Objective To investigate the value of high-dose dobutamine stress echocardiography combined with two-dimensional strain imaging in early diagnosis of coronary artery disease. Methods Highdose dobutamine stress echocardiography was performed to 28 patients with suspected coronary artery disease. All wall movements were observed during resting condition and at all stress levels,respectively;the peak systolic longitudinal strain in each endomyocardial segment of left ventricular was measured; the sensitivity and specificity between visual method and two-dimensional strain imaging in diagnosing myocardial ischemia with high-dose dobutamine stress echocardiography were compared. The average peak systolic longitudinal strain was calculated against control group, coronary artery disease group during ischemia segments and non-ischemia segments, and a comparison was made inside each group as well as against the other groups. The area under receiver operating characteristic curve of the peak systolic longitudinal strain was used to predict the sensitivity and the specificity of myocardial ischemia. Results With dobutamine dose of 40 μg·kg-1 · min-1 ,wall motion abnormalities were diagnosed in 6 patients (20 segments) through visual method, myocardial ischemia was found in 15 patients (148 segments) through computing the peak systolic longitudinal strain. Inside the coronary artery disease group during ischemic segments,the majority of peak systolic longitudinal strain was significantly reduced ( P<0.05) compared to the non-ischemic segments and the control group. In diagnosing myocardial ischemia in high-dose dobutamine stress echocardiography, the sensitivity of visual method and two-dimensional strain imaging were 35.3% and 88.2%(P<0.01), specificity 100% and 100%(P>0.05), and accuracy 60.7% and 92.8% (P<0.01). The cutoff value of the peak systolic longitudinal strain was less than or equal to 14.9%, its sensitivity and specificity in predicting myocardial ischemia were 83.3% and 91.7%,respectively. Conclusions High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can increase the sensitivity of detecting myocardial ischemia and detect concealed myocardial ischemia. High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can be used in early diagnosis of coronary artery disease.

Objective No uniform standards has been established for the clinical diagnosis of schizophrenia .The article was to investigate the differentially expressed microRNA ( miRNA) profile and explore its clinical significance . Methods Differentially expressed miRNAs were screened by FlashTag TM Biotin RNA chips and SAM software in serum of patients with schizophrenia and healthy controls , then the validation was performed by real-time fluorescent quantitative reverse transcription polymerase chain reaction ( RT-PCR) . Results Three differentially expressed miRNAs were screened , including up-regulated hsa-miR-1281 ( fold change =1.50881) and two down-regulated miRNAs:hsa-miR-2861(fold change=0.642) and hsa-miR-638 (fold change=0.516).The com-parative analysis of RT-PCR by SPSS 17.0 Kruskal Wallis H Test validated the expression levels of hsa-miR-2861 and hsa-miR-638 in patients with schizophrenia decreased significantly in comparison to healthy controls (χ2 =4.089,χ2 =4.083, P<0.001).While the expression level of hsa-miR-1281 in patients with schizophrenia was in higher expression level compared with control group (χ2 =5.333, P<0.001). Conclusion There are differentially expressed miRNA profile in serum of patients with schizophrenia , in which miR-1281 , miR-2861 and miR-638 could be new serum markers for diagnosis of schizophrenia .
