Objective To determine loganin in productions of Liuweidihuang. Methods The chromatographic column was shim-packvp ODS-C18 (4.6 mm?150 mm,5 ?m),the mobile phase was THF-acetonitrile-methanol-0.05%H4PO3 (1∶8∶4∶87),the detection wavelength was 236 nm,the temperature of column was 40 ℃ and the flow rate was 1.0 mL/min. Results A good linearity of loganin was in the range of 4.42?10-2～22.1?10-2 ?g,r =0.999 7,and the average recovery rate was 98.96% (n =6,RSD=1.42%). Conclusion The method provided a reference for evaluating and controlling quality of series productions of Liuweidihuang.

Objective To observe the serum cardiac troponin I (cTnI) level and to analysis the relations between the serum cTnI level and prognosis in patients with dilated cardiomyopathy (DCM) and Cardiac Dysfunction.Methods Serum cardiac cTnI level was measured by enzyme-linked immunosorbant assay. Results The serum cTnI level in DCM patients with class IV cardiac function (0.53 ?0.31) ?g/L was significantly higher than in DCM patients with class Ⅲ cardiac function (0.45?0.27) ?g/L.There was significantly difference in serum cTnI levels between DCM patients with class Ⅲ cardiac function and DCM patients with class Ⅱ cardiac function(0.29?0.27) ?g/L.Conclusion The higher serum cTnI level is correlated with the severity of cardiac function and may be useful for evaluating prognosis in patients with DCM.

OBJECTIVE: To explore the sources and structures of the main impurities in compound tilidine hydrochloride oral solution.

we have designed a program-controlled high-fi amplifier for EMG.Its gain can be controlled by computer.The program-contralled circuit is implemented with numerical control resistor.The amplifier can be used in automatically measuring EMG signals over 100?v.The circuit is characterized by easy de- sign,simple programing and convenient control.

Objective To analyze the correlation of Brown attention deficit disorder scale(BADDS)parent form and Conners parent ratting scale(CPRS)in Chinese children ages 8-12.Methods Both BADDS parent form and CPRS on 146 children ages 8-12 in an elementary school in Xicheng district in Beijing were admmistered,and the results were compared with statistic methods.Results Total scores on the BADDS parent form were highly correlated with CPRS index scores(r=0.739,0.771 Pa

0.05). But there was more BMP in the treated group of periodontitis than the other groups(P

Objective To observe the influences of electroacupuncture(EA) on the morphological changes in neurons and glia cells in sacral dorsal commissural nucleus(SDCN) of rats with ulcerative colitis(UC),and study the mechanism of acupuncture in modulating central nervous system in UC.Methods Forty-eight male SD rats were randomly assigned to four groups: control group,UC model group,EA Tsusanli group(UC plus EA at Tsusanli acupoint) and EA non-acupoint group(UC plus EA non-acupoint group).According to the acupuncture duration,EA Tsusanli group was divided into three subgroups: 1-day,3-day and 5-day subgroup(8 rats for each subgroup).UC model of rats was reproduced by instillation of a solution containing ethanol and 2,4,6,-trinitrobenzenesulfonic acid(TNBS) into the distal colon.When the treatment was ended,all the rats were sacrificed and SDCN slides were prepared.The expressions of Fos,glial fibrillary acidic protein(GFAP) and OX42 immunoreactivity in SDCN were assessed and calculated by using single or double immunohistochemical methods.Results In the three experimental groups,the Fos-positive neurons,GFAP-positive astrocytes and OX42-positive microglia were mainly expressed in SDCN.In UC model group and EA non-acupoint group,the expressions of Fos,GFAP and OX42 immunoreactivity were stronger than those in EA Tsusanli group(P

Objective To investigate the incidence of candidal colonization and to analyze its risk factors in patients with connective tissue diseases (CTDs). Methods Throat swabs, midstream urine and anal swabs from 153 patients with CTDs and 63 healthy volunteers were collected for fungus culture. The logistic regression was completed via the software package SPSS 11.0. Results The incidence rate of candidal colonization was higher in the patients than that in the healthy controls (35.29% vs 7.59%). Of all the isolated fungus strains, the proportion of Candida albicans was the highest. The logistic regression analysis revealed that decrease of blood erythrocytes, increase of urine protein, decrease of complements such as CH50, C3 and C4 in serum, high daily dosage of corticosteroids and broad-spectrum antibiotic administration all significantly increased the risk of candidal colonization (all P 0.05). Conclusions The incidence rate of candidal colonization in patients with CTDs is higher than that in healthy controls. Avoiding the risk factors will help to decrease the incidence of candidal colonization in CTDs.
