Effectiveness of Bushen Huoxue Granule (补肾活血颗粒) on 5-Serotonin and Norepinephrine in the Brain of Parkinson's Disease Patients with Depressive State

Objective：To observe the clinical curative effect of Chinese medicine Bushen Huoxue Granule（补肾活血颗粒,BHG） on Parkinson＇s disease（PD） patients with depressive state.Methods：Sixty-two PD patients with depressive state were randomly assigned to two groups by using a random number table,31 in each group.Madopar was given to all as the conventional treatment.The fluoxetine hydrochloride dispersible tablet was given to the patients in the control group and BHG was given to those in the treatment group.The therapeutic course for all was 12 weeks.Before and after treatment,Hamilton depression rating scale（HAMD） was applied to judge the curative effect,and the changes of cerebral neurotransmitters levels in the brain of patients were detected by encephalofluctuograph technique.Results：The scores of HAMD in the two groups were decreased markedly after 12-week treatment.It was lower in the treatment group than that in the control group with significant difference（P〈0.01）.The contents of norepinephrine（NE） and 5-serotonin（5-HT） in the PD patients were obviously lower than normal value.There was no significant difference between the two groups before treatment（P〉0.05）.The contents of NE and 5-HT were all increased in the two groups after treatment（P〈0.05）,with significant differences between the two groups（P〈0.01）.Conclusion：BHG could increase the contents of NE and 5-HT in PD patients＇ brain to improve the depressive state of PD patients.

Interleukin-10 genotype protects end stage renal disease patients from microinflammation and arteriosclerosis

End stage renal disease （ ESRD ） and cardiovascular disease are induced by arteriosclerosis （AS）. The latest investigation shows that AS is a special inflammatory state. The constant inflammation,which has been defined as a micro inflammatory state is related to the decline of renal function and blood purification, but not the result of infections caused by external pathogenic microorganisms or internal opportunistic pathogenic microorganisms. We investigated the mechanism of interleukin-10 （IL-10） gene-1082 A/G protection effect to keep ESRD patients away from micro inflammation and AS.

Brain activity in Parkinson's disease patients with mild cognitive impairment

Mild cognitive impairment （MCI） is common in patients with Parkinson＇s disease （PD）, yet the underlying neural mechanisms of this disease state remain unclear. We investigated alterations in the spontaneous brain activity of PD patients with MCI （PD-MCI） relative to cognitively normal PD patients （PD-CN） and healthy control （HC） subjects. In this work, 13 PD-MCI patients, 16 PD-CN patients, and 16 HC subjects completed resting state functional MRI. Spontaneous brain activity was measured by calculating amplitude of low frequency fluctuation （ALFF） values across the whole brain. Between-group differences and correlations between ALFF values and cognitive test scores were analyzed. ALFF values decreased in the right superior temporal gyrus and increased in the left middle temporal gyrus and left superior frontal gyms of PD-MCI patients compared with PD-CN patients. In the PD-MCI group, ALFF values in the left middle temporal gyrus were negatively correlated with Montreal Cognitive Assessment and vocabulary test scores, and the ALFF values in the left superior frontal gyms were negatively correlated with vocabulary test scores. Our study demonstrates that PD-MCI is associated with abnormal spontaneous brain activity in the temporal and frontal lobes. These findings inform the underlying neural mechanism of cognitive impairment in PD.
