Neurosurgery in Parkinson's disease:Social adjustment, quality of life and coping strategies

Subthalamic nucleus deep brain stimulation has become a standard neurosurgical therapy for ad- vanced Parkinson＇s disease. Subthalamic nucleus deep brain stimulation can dramatically improve the motor symptoms of carefully selected patients with this disease. Surprisingly, some specific dimensions of quality of life, ＂psychological＂ aspects and social adjustment do not always improve, and they could sometimes be even worse. Patients and their families should fully understand that subthalamic nucleus deep brain stimulation can alter the motor status and time is needed to readapt to their new postoperative state and lifestyles. This paper reviews the literatures regarding effects of bilateral subthalamic nucleus deep brain stimulation on social adjustment, quality of life and coping strategies in patients with Parkinson＇s disease. The findings may help to understand the psychoso-cial maladjustment and poor improvement in quality of life in some Parkinson＇s disease patients.

Effect of Feitai Capsule(肺泰胶囊) on Quality of Life and Progression-Free Survival of Patients with Unresectable Non-Small Cell Lung Cancer

Objective： To examine the effect of a Chinese medicinal herbal formula （Feitai Capsule, 肺泰胶囊） on the quality of life （QOL） and progression-free survival （PFS） of patients with unresectable non-small cell lung cancer （NSCLC）. Methods： Sixty-two patients were randomly divided into the treatment group （31 cases） and the control group （31 cases）. For the treatment group, 4 capsules （1.2 g/capsule） of Feitai Capsule were administered 3 times a day after meals for 3 weeks; then no drug was administered for 1 week. This schedule was continued for at least 3 more cycles （12 weeks totally）. If there were no obvious toxic reactions, the treatment was extended. The patients were evaluated at least once every 8 weeks until progressive dJsease （PD）. For the control group, the regular follow-up and evaluation were performed at least once every 8 weeks until PD. Clinical symptoms, objective response, physical constitution and energy, QOL, and PFS were evaluated regularly. Analysis of variance （ANOVA）, a non-parametric test, and analysis of covariance were used to compare clinical features, amelioration of clinical symptoms, physical constitution and energy, and QOL. Kaplan- Meier analysis was used to compare the two-group PFS. Results： Sixty patients finished the final evaluation, with 30 patients in each group. Baseline characters between groups were not significantly different （P〉0.05）. The control group had a 36.7% improvement in clinical symptoms, while the treatment group had a 73.3% improvement. This difference was statistically significant （Z=-2.632, P=0.008）. The control group had a 26.7% improvement in the Karnofsky performance status （KPS）, while the treatment group had a 53.4% improvement. This was also significantly different （Z=-2.182, P=0.029）. A comparative analysis indicated a positive correlation （r=0.917, P〈0.001）. Compared with the control group, QOL in the treatment group was significantly improved, except in the social/family condition and doctor-patient relationship indicators. The PFS of the treatment group and control group were 6.23 months and 4.67 months, respectively （P=0.048）. Conclusion： Feitai Capsule, a Chinese medicinal herbal treatment could improve the QOL and extend the PFS of the unresectable NSCLC patients.
