Objective To assess the prevalance and distribution of pain in Parkinson' s disease (PD) patients, and to describe the relationship between pain and development of disease and its impact on the quality of life. Methods 113 PD patients were assessed with Visual Analog Scale (VAS), Brief Pain Inventory (BPI), Unified Parkinson' s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale (H-Y), Hamilton Anxiety and Depression Scale (HRSD, HAMA) and Pittsburgh Sleep Quality Index (PSQI). Patients were divided into no pain group, PD-pain group and non-PD-pain group. PD-pain group was divided into PD-pain direct group and PD-pain indirect group. And statistical analysis was performed for each group. Results The incidence of PD-pain was 42. 5% (48/113). And compared with no pain group, PD-pain group had earlier age at onset of disease, longer duration, higher HAMA, HRSD, UPDRS and H-Y score, higher daily L-dopa dose, with statistical significance. Compared with non-PD pain group, the differences in the onset of age (57.4±9.6 vs 65.9±8.7, t= -2.596, P =0.012), HRSD(12. 9±7.9 vs 8.7±3.7, t =2.605, P=0.014) and VAS (61.6±25.9 vs 38.0 ± 30. 1, U = -2.290, P =0.022) were also statistically significant. BPI was different between PD-pain direct group and PD-pain indirect group except normal work and relations with other people. Conclusion Pain is frequent in Parkinsonian population. Most pain was chronic and related to PD (PD-pain). These patients always have earlier onset age and poorer quality of life.

Objective To systemically evaluate the therapeutic effect of pramipexole in treating Parkinson's disease. Methods Pubmed, Embase, Cochrane Database were used to search for randomized control trials (RCTs) on Parkinson's disease treated with pramipexole. Meticulous data wre extracted and meta-analysis was performed according to a preset protocol. Results Ten RCTs involving 1738 patients were included. The results of meta-analysis showed that pramipexole decreased the total scores of unified Parkinson's disease rating scale [UPDRS, WMD=-10.01,95%CI (-12.76,-7.26)],UPDRS part [WMD=-2.44,95%CI(-2.93,-1.95)],and UPDRS partⅢ[WMD=-6.61,95%CI(-8.38,-4.84)]. Pramipexole also reduced the score of UPDRS part Ⅳ[WMD=-0.73,95%CI(-1.16,-0.30)] in advanced patients(P<0.05=.Three studies referred to the effect of pramipexole in treating parkinsonian tremor. However there was a clinical heterogeneity among the studies, and two of them revealed a significant difference. Conclusions Pramipexole might improve motor symptoms and the quality of life in advanced patients, as well as improve tremor, which needs more RCTs to be confirmed.

Objective To study the efficacy of entacapone for motor fluctuations in Parkinson's disease. Methods Pubmed, Embase, Cochrane Database were searched for randomized controlled trial studies (RCTs) on entacapone compared to placebo in the treatment of Parkinson' s disease with motor fluctuations. Data were extracted and evaluated by two reviewers independently with designed extractian form. Revman 4. 2. 10 software was used for data analysis. Results Ten RCTs involving 2212 patients were included. The Results showed that entaeapone tends to increase "on" time, decrease "off" time and daily levodopa dosage (WMD=-1.41,95% CI -2. 09- -0.72) and improve "on" time motor symptoms and the quality of life. But it might increase the rate of dyskinesia (OR=2.00, 95% CI 1.55-2.58).Conclusion The systematic review indicates that entaeapone might be an effective agent for parkinsonian patients with motor fluctuations and more high quality RCTs with the same effect measures are required.
