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 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.

Objective To observe the effects of Shenfu injection on intestinal mucosal barrier of rats with hepatic ischemia-reperfusion.Method Ninety SD male rats and weight from 230 to 270g were randomly divided into three groups( 30 rats in each),and 30 rats in each group divided again into 6h and 12h group( 15 rats in each):(1)SO group received sham operation(SO);(2) IR + NS group received so and 0.9 normal saline intravenously imediately before the ischemia reperfusion injury;(3) IR + SF group received Shenfu injection intravenously imediately before the ischemia reperfusion injury,IR + NS group and IR + SF group occlusion of the hepatoduodenal ligament,and endotoxin,ALT and MDA were detected.Results The levels of ALT,MDA in IR + NS group were higher than those in IR + SF group,and the rate of bacterial translocation( BT)group.

Objective To develop a PCR-SSP method for detection of HLA-DRB1 alleles in the patients who were hypersensitive to Platanus Acerifolia pollen allergen,and to probe into the association between the atopic subjects to Platanus Acerifolia pollen allergen and HLA-DRB1 alleles.Methods DNA in whole blood was extracted by phenol-chloroform method.Eight pairs of specific primers for alleles were synthesized,and HLA-DRB1*0401,*0402,*0403,*0404,*0405,*0406,*0407,*0408 alleles in 20 atopic patients and 36 healthy individuals of Jiangsu Province with Han nationality were detected by PCR-SSP(polymerase chain reaction-sequence specific primer).Results By optimizing the experimental conditions PCR-SSP methods for detection of the 8 alleles were established and the distributing data of above-mentioned HLA DRB1 were obtained.The frequency of HLA DRB1*0405 and *0406 in the patients group was higher than that of in healthy controls group,while the frequency of HLA DRB1*0402 in the patients group was lower than that in controls.No significant deference for the other 5 alleles was found between the 2 groups.Conclusion HLA-DRB1*0406和*0405 seems to be the likely suspected candidate alleles responsible for susceptibility to Platanus Acerifolia pollen allergen in the atopic patients,while DRB1*0402 might be contribute to the related resistance to the allergen.
