RESUMO
Objective:To evaluate the effectiveness of Minqing Ao dental desensitizer in the treatment of early childhood caries (ECC).Methods:41 0 teeth with ECC in 1 1 0 cases were divided into 3 groups.Minqing Ao dental desensitizer,fluoride toothpaste and ordinary toothpaste without fluoride were respectively used in group A,B and C.The laser fluorescence value(LFV)was meas-ured and compared before treatment,2,4,6 weeks and 6 months after treatment.Results:2 weeks after treatment,the LFV was not significantly changed in the 3 groups.4 weeks after treatment LFV in group A was decreased(P0.05).6 weeks after treatment LFV in group A and B was decreased(P<0.01 and P<0.05),there was significant difference be-tween each 2 groups(P<0.05).6 weeks and 6 months after treatment LFV in group A was lower than that in group B(P<0.01 ),and in group B was lower than that in group C(P<0.01 ).Conclusion:Minqing Ao is effective for treatment of early childhood caries.
RESUMO
Objective To observation the clinical effect of anesthesia combined with epidural block for patients with COPD surgery.Methods 262 cases with COPD needed to line the chest and abdominal surgery and urology surgery patients.Patients were divided into control group and observation group according to the time sequence,underwent general anesthesia and anesthesia combined with epidural anesthesia,contrast observed in patients with operative time,postoperative extubation time,wake time and the analgesic effect of anesthesia (VAS score) was measured in patients with FVC,FEV1/FVC and FEF25％ to 27％ lung function,clinical efficacy and complication rate of two anesthesia methods.Results The patients extubation time,recovery time and VAS scores were significantly lower than those of control group,the differences were statistically significant(all P ＜0.05).Group of postoperative patients with FVC,FEV1/FVC and FEF25％ to 27％,such as lung function test results were significantly better than those of control group,and the difference was statistically significant (all P ＜0.05).Anesthesia control group total effective rate of 87.0％ observed in patients anesthesia total effective rate was 96.9％.Compared with the control group,the anesthesia clinical effect of the observation group was statistically significant (P ＜0.05).Operative time and postoperative complication rate of the two groups of patients showed no significant difference(P ＞0.05).Conclusion Anesthesia combined with epidural anesthesia used in surgery in patients with COPD can effectively improve the clinical effects of anesthesia,to enhance the safety of anesthesia,which will help the rehabilitation of patients and worth of clinical practice.
RESUMO
The effect of sample vial type and cocktail quantity on tritium measurement in liquid scintillation counting is studied in this paper. With both high and low level tritium samples, glass vials allow higher counting rates than plastic vials do. We also present detailed analysis of the way to obtain the optimal counting condition by dispensing different quantity of cocktail into sample vials. Results indicate that the optimal counting condition has little relationship with tritium concentration in the sample. The main factor which influences the counting is the quantity of cocktail added into samples. Figure of merit is employed to access the results, which increases as the quantity of cocktail increasing. But when the ratio of cocktail and sample reaches 2.0, increase of ratio makes little contribution to the counts, and the disintegrations per minute comes nearly to be a constant.
