Objective To evaluate the efficacy and safety of pramipexole in treating restless legs syndrome (RLS).Methods A search for randomized,double-blind,and placebo-controlled clinical trials of pramipexole in treating moderate to severe RLS using CNKI,PubMed,Embase and Cochrane Library database was carried out. A meta-analysis of included clinical trials was performed with RevMan 5.0 software.The 2 outcomes that the weighted mean difference(WMD) of change from baseline in International RLS Study Group rating scale(IRLS) score and the relative risk (RR) of response based on the Clinical Global Impression-Improvement (CGI-I) scale score were calculated for efficacy.Safety was assessed with RR of the adverse event (AE).Results A total of 5 clinical trials were included in this meta-analysis,of which 1776 patients were randomly assigned (945 on pramipexole,831 on placebo).The records of patients were pooled.Overall WMD were - 6.34 ( Z =12.76,P ＜ 0.01 ) for the change from baseline in IRLS score,and RR of response based on CGI-I were 1.65 (Z =10.39,P ＜0.01).The overall RR of pramipexole versus placebo were 1.14 ( Z =1.87,P =0.06 ) for AE.Conclusion To treat RLS,pramipexole is an effective and safe drug.

Delightful achievements have been obtained in forestry genetic breeding since the application of transgenic technology in this field during the past 20 years. Field trials of some genetic modified (GM) trees have been carried out, and some GM trees have been commercialized. Meanwhile, the risks of ecological safety caused by GM trees have raised attention in the public gradually. These issues mainly include the horizontal transfer and vertical flow of foreign genes, and the potential effects on insects, soil ecosystems and virus. The current status of field trials, commercial applications and the potential ecological risks of GM trees were summarized. Then the prospects of GM trees were also presented.

The objective of this study was to assess the clinical evidence for or against mood stabilizers as a treatment for Alzheimer's disease (AD). We searched 5 databases from their inception to January 2010. Five randomized clinical trials of mood stabilizers to treat human patients suffering from AD were included. These trials assessed the effectiveness of mood stabilizers as an adjunct treatment to conventional anti-dementia drugs on behavioral and psychological symptoms, especially on agitation. Methodological quality was assessed using the Jadad score. The results suggested a significant effect in favor of placebo on the Mini-Mental Status Examination [n=270, weight mean difference (WMD), -0.89; 95% confidence intervals (CIs) -1.69 to -0.09, P=0.03] and on the Neuropsychiatric Inventory total (NPI total) (n=51, WMD, 3.71; 95% CIs 0.15 to 7.26, P=0.04). There were no significant differences in change scores on total Brief Psychiatric Rating Scale (BPRS total), NPI/BPRS agitation, Cohen-Mansfield Agitation Inventory total and Physical Self Maintenance Scale between mood stabilizers and placebo. Only one of these studies was free of methodological limitations (Jadad score=5). In conclusion, based on the existing evidence, mood stabilizers are ineffective or even harmful as a treatment for AD.

Objective To observe the effect of early rehabilitation treatment at different time point on the motor function and activity of daily living (ADL) and emotion in acute stroke patients. Methods 120 patients with acute stroke were randomly assigned to three reha-bilitation groups and one control group according to the disease course (3 days, 5 days, 8 days when the disease is steady). Each group con-sisted of 30 eases. The patients in each group were treated with the regular medication therapy, rehabilitation groups were treated with com-prehensive rehabilitation treatment including Bobath technique therapy. Neurological deficit, motor function, balance function, ADL, emo-tion of all the patients were assessed before and 21 days after rehabilitation intervention. Results After treatment, the motor function, bal-ance function, ADL and emotion of each rehabilitation group were improved. The patients'rehabilitation scores in FMA, Fugl-Meyer balance function, MBI and HRSD got much better than that in control group. The difference was statistic significant. The effect of rehabilitation treat-ment did not show difference among rehabilitation groups. Conclusion Early rehabilitation treatment for acute stroke does benefit for stroke patients. Effect does not show vary with the start time of rehabilitation treatment within 8 days after acute stroke.

Objective To analyze the change of schistosomiasis endemic situation in Hubei Province, 2008. Methods The data of schistosomiasis control in the whole province, surveillance sites and standard examinations were collected and analyzed. Results Among all the 63 endemic counties (cities, districts), 21 reached the criteria of transmission interruption, 19 reached the criteria of transmission control, and 23 reached the criteria of infection control in 2008. Villages of Category Three, Category Four and Category Five accounted for 52.10% , 27.80% and 20.09% of all the endemic villages in the whole province, respectively. The infection rates of population and cattle were 1. 70% and 2. 20% , which decreased by 27. 04% and 34. 33% when comparing to those in 2007. The snail area was 77 363 hm~2, with a reduction of 315.70 hm~2 comparing to 2007. In the 74 provincial surveillance sites, the infection rate of population and cattle were 1. 32% and 1. 85% , respectively, with reduction rates of 32.99% and 68.38% comparing to 2007. The snail area was 2 833.98 hm~2 and the area with infected snails was 215.35 hm~2, the densities of living and infected snails were 0. 37 snails/0.1 m~2 and 0.000 3 snails/0. 1 m~2, respectively, and the infection rate of snails was 0.08%. Comparing to 2007, the snail area, densities of living and infected snails and the infection rate of snails decreased by 3.81 % , 21.28% , 40.00% and 27. 30% , respectively, while the area with infected snails increased by 4.52%. The results of standard examination suggested that all the 15 uncontrolled counties ( cities, districts) reached the criteria of infection control. Conclusions Though the endemic situation of schistosomiasis in Hubei Province has been controlled effectively, the endemic condition is still severe. Therefore, the comprehensive measures with an emphasis on infectious source control should be strengthened to consolidate the control result.

Objective To investigate the efficacy and safety of pramipexole versus fluoxetine in the treatment of depression in Parkinson's disease ( PD). Methods A randomized, clinical trial of pramipexole versus fluoxetine treatment for 12 weeks in 50 patients suffering from combined PD and depression was accomplished. The efficacy and safety assessments of the treatments were performed at different time points. Results For the intent-to-treat (ITT) population, the Hamilton Depression Rating Scale (HAMD) scores decreased progressively in both the pramipexole and the fluoxetine group, and a between-time statistical analysis was significant for both groups. The efficacy proportion of patients who responded to the treatment, as defined by at least a 50% reduction in HAMD score, was 56. 0% in the pramipexole group versus 48. 0% in the fluoxetine group (χ~2 =0. 321, P>0. 05). Similarly, the proportion of patients who recovered, as defined by a final HAMD score ≤8, was 52. 0% in the pramipexole group versus 32. 0% in the fluoxetine group (χ~2 =2. 053, P>0. 05) , but the difference between the two treatments showed no statistical significance. At the endpoint, both the Unified Parkinson's Disease Rating Scale (UPDRS) part Ⅱ and part Ⅲ subscores improved in the pramipexole group, by a mean of 2. 9±3. 7 (t= 2.366, P<0.05) and7.2±5.1 (t=2.654, P< 0.05), respectively, and the latter was significantly different from the change in this variable of the fluoxetine group (P<0. 05). Spearman analysis showed that no relationship between HAMD score and UPDRS Part II or Part III subscore. The findings for the per-protocol (PP) population were consistent with the above results, except that the proportion of patients who recovered in the pramipexole group was significantly larger than that in the fluoxetine group. The adverse events in both groups were mild dizziness, nausea and anorexia. No significant difference was found in the frequencies of the adverse events between the pramipexole and fluoxetine group. Conclusions Pramipexole is effective and safe in the treatment of Chinese PD patients combined with depression.

Objective To investigate the efficacy of combined high-dose intravenous immunoglobulin (IVIG) pulse therapy in patients with severe systemic lupus erythematosus (SLE). Methods Thirty-six patients were enrolled into this study, and randomly classified into WIG group (n=17) and methylprednisolone (MP) group (n=19). The treatment of patients in MG group began with a 3-day intravenous MP followed by intravenous WIG 400 mg per kilogram of body weight per day for 3-5 days, then was switched to oral prcdnisone and cyclophosphamide at routine dose. Intravenous MG was given repeatedly with an interval of 1 month for 2-5 sessions. Patients in MP group were treated with the same corticosteroids and immunosuppressants as used in WIG group but without IVIG. Patients were followed up for 3-12 months.The clinical efficacy, related serum parameters, and systemic lupus activity measurement (SLAM) were evaluated and compared between the two groups. Results Most patients in both groups showed a remission of symptoms and reduction in disease activity after treatment. The decrease in SLAM, positivity rates of antinuclear antibodies and anti-double-stranded DNA (anti-dsDNA) antibodies as well as the increase in platelets were faster in IVIG group than those in MP group (all P<0.05), but the long-term efficacy of the two groups was similar (P>0.05). Infections occurred in 11.8% of patients in WIG group and 36.8% of patients in MP group. Conclusions High-dose intravenous immunoglobulin may serve as an effective aid in the treatment of severe SLE, and is particularly beneficial to patients resistant to corticosteroids and immunosuppressants of routine dose and those accompanied by severe infections and intolerable to high dose of corticosteroids and immunosuppressants.
