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 curative effect and recurrence rate of desmopressin acetate(DDAVP) combined with bladder training therapy on primary nocturnal enuresis(PNE) in chlidren.Methods One hundred children with PNE were randomly divided into control group and observation group(50 cases in each group).Children in control group were treated with simple DDAVP,and patients in observation group were treated with bladder training while DDAVP was using.The course of treatment were 3 months.The therapeutic effect between the 2 groups when the treatment was finished was compared and then followed up all the cases for 3 months to compare the near-term and long-term recurrence rate between the 2 groups.SPSS 13.0 software was used to analyze the data.Results The total effective rate in control group was 72.9%,and the near-term recurrence rate and the long-term recurrence rate were 22.9% and 54.3%,respectively.The total effective rate in observation group was 91.3%,and the near-term recurrence rate and the long-term recurrence rate were 11.9% and 28.6%,respectively.The total effective rate was significantly higher in observation group than that in control group(Z=-1.972,P=0.049).The near-term recurrence rate in 2 groups had no significant difference(?2=1.632,P=0.201).The long-term recurrence rate was extremely lower in observation group than that in control group(?2=5.249,P=0.022).Conclusions There is significant curative effect that DDAVP combined with bladder training therapy on PNE in children,and it can lower the long-term recurrence rate.
