Objective To study the clinical therapeutic effect of combination of Naodekang capsule and western medicine for treatment of patients with mental disorders after bilateral cerebral frontal lobes contusion and laceration.Methods A prospective study was conducted. Sixty-two patients with mental disorders after bilateral frontal lobes contusion and laceration hospitalized from June 2012 to January 2014 in the Department of Neurosurgery in Liangzhou Hospital, Wuwei City, Gansu Province were enrolled. According to random principle, they were divided into combined traditional Chinese and western medicine treatment group (32 cases) and western medicine treatment control group (30 cases). Conventional symptomatic therapy was given to both groups. In the western medicine control group, based on the above conventional treatment, antipsychotic drug risperdal (risperidone) was given, the beginning dosage was 4 mg daily and gradually reduced to 1 mg daily. In combined traditional Chinese and western medicine group, beside the conventional therapy, oral Naodekang capsules and oral risperdal were given. The ingredients of the capsule included: Astragalus 60 g, Radix Paeoniae Rubra 15 g, Rhizoma Chuanxiong 25 g, Angelica 15 g, Earthworm 10 g, Semen Persicae 10 g, Safflower 15 g, Salvia miltiorrhiza 15 g, Rhizoma Gastrodiae 15 g, Uncaria 10 g, Bupleurum 20 g, Pueraria 15 g, Rhizoma Acori Tatarinowii 15 g; the patients took once 3 capsules, three times a day, and risperdal 2 mg per day at the beginning and gradually reduced to 1 mg daily. Before treatment and after treatment for 2, 6 and 12 weeks, the brief psychiatric rating scale (BPRS) score was applied to evaluate the clinical therapeutic effect on the situation of patients' improvement of symptoms; in the two groups, the clinical curative effects were observed and when the psychiatric symptoms were controlled, the mean dosage of antipsychotic western medicine used daily in each patient was calculated.Results After treatment, the BPRS scores in the two groups were lower than those before treatment, from 6 weeks after treatment, the degree of descent in the BPRS score in the combined treatment group was more significant than that in the western medicine group (38.68±7.81 vs. 54.05±6.75,P < 0.05), and the descent was persistent until 12 weeks after treatment (15.46±8.51 vs. 23.98±8.03,P < 0.05). The cure rate of the combined group was markedly higher than that in western medicine group [84.4% (27/32) vs. 76.6% (23/30),P < 0.05]. When the psychiatric symptoms were controlled, the dosage of antipsychotic western drug used in each patient in the combined group was less than that in western medicine group (mg/d: 1.5±0.1 vs. 2.8±0.2,P < 0.05).Conclusion The westernconventional therapy combined with traditional Chinese medicine Naodekang capsule for treatment of mental disorders after bilateral cerebral frontal lobes contusion and laceration has relatively good therapeutic effect.
