ObjectiveTo evaluate the clinical efficacy of Sedum freckle capsule combined with hydroquinone cream phonophoresis in the treatment of chloasma.MethodsA total of 180 patients with chloasma were recruited into two groups according to the random number table, 100 in the treatment group and 80 in the control group. The patients in the control group were treated with 2% hydroquinone cream phonophoresis, and those in the treatment group received 2% hydroquinone cream phonophoresis and Sedum freckle capsules, both for 2 months. The symptom and lesion score were usedto evaluate the clinical efficacy. ResultsThe cure rates were 81.00% in the treatment group and 67.50% (χ2=4.320,P=0.038) in the control group at the end of treatment, 92.0% and 76.3% (χ2=5.538,P=0.019) at 2 months follow-up. The total lesion scores at the end of treatment and at 2 months follow-up were significantly lower than before the treatment in the treatment group (1.61 ± 0.84 and 1.30 ± 0.85vs.3.48 ± 1.02;t=14.152, 16.419, allP<0.01) and also in the control group (2.04 ± 0.61 and 2.03 ± 0.51vs.3.45 ± 1.09;t=10.097, 10.554, allP<0.01). The total lesion score at the end of treatment and at 2 months follow-up were significantly lower than in the treatment group was significantly decreased than the control group (t=3.839, 6.767; allP<0.01).ConclusionSedum freckle capsule combined with hydroquinone cream phonophoresis could effectively treat patients with chloasma.
Résumé
Objective To explore the efficacy of closed reduction with cannlated compression screws for the treatment of elderly paitents with intertrochanteric fracture.Methods From April 2002 to July 2006,guided by a C-arm X-ray system,58 elderly patients with intertrochanteric fracture were treated by closed reduction with cannlated compression screws.Results The mean operation time was 55 minutes(40 to 70 minutes),and the mean blood loss was 35 ml(30 to 40).The patients were discharged from hospital in 3 to 10 days after the operation(mean,6.5 days).All of the 58 patients were cured.According to criteria for evaluating the outcomes of intertrochantenic fracture,28 cases were excellent,25 were good,3 were fair,and 2 were poor.The Rate of excellent and good outcomes was 91.4%(53/58).Conclusion Closed reduction with cannlated compression screws is effective for elderly paitents with intertrochanteric fracture.
