RESUMEN
Objective@#To explore the curative effect and safety of botulintum toxin A (BTX-A) on depressive disorder in patients with Parkinson′s disease (PD).@*Methods@#Forty-two cases of PD with depression prospectively recruited in the Second Hospital Affiliated to Soochow University from August 2016 to November 2018 were divided into two groups: 28 patients in BTX-A group (administered with 100 U BTX-A injection on patients′ eyebrow, forehead, bilateral lateral canthus and temporal region at 20 loci), 14 patients in sertraline (control) group (administered with 50-100 (55.36±14.47) mg/d sertraline). The scores of Hamilton Depression Rating Scale (HAMD), Self-rating Depression Scale (SDS), Hamilton Rating Scale for Anxiety (HAMA), Self-rating Anxiety Scale (SAS) after treatment for 2 weeks, 4 weeks, 8 weeks and 12 weeks were compared with the scores of each emotional rating scale for baseline respectively. Meanwhile, the differences in the scores of each emotional scale between the two treatment groups were compared. In addition, the remission rates of depression and anxiety (defined as HAMD, HAMA scores<7) at each follow-up time point between the two groups were compared to evaluate the efficacy and safety of BTX-A in the treatment of PD patients with depression.@*Results@#The scores of HAMD, HAMA, SDS, SAS in the BTX-A group and the sertraline group reduced compared to baseline after treatment (at the 2nd, 4th, 8th, 12th weeks). The scores of HAMD and SDS in the BTX-A group (HAMD scores: F=12.930, P<0.01; SDS scores: F=5.022, P=0.001) and those in the sertraline group (HAMD scores: F=2.883, P=0.030; SDS scores: F=3.427, P=0.013) were significantly lower compared to baseline, but there was no statistically significant difference in the scores of HAMD and SDS between the two groups (P>0.05). HAMD score showed that the remission rate of depression in the BTX-A group (17.9% (5/28), 35.7% (10/28)) was higher than that of the sertraline group (2/14, 4/14) at the 2nd and 4th weeks. At the 8th and 12th weeks, the remission rate of depression in the sertraline group (7/14, 9/14) was higher than that of the BTX-A group (46.4% (13/28), 53.6% (15/28)). There was no statistically significant difference in remission rate of depression between the two groups at each follow-up time point (P>0.05). There was no statistically significant difference in HAMD scores between males and females in the BTX-A group (P>0.05). Two of the 28 patients in the BTX-A group had frown muscle stiffness, which lasted for two weeks and improved in one month. Two patients in the sertraline group had headache and dizziness, and two patients had dry mouth and nausea, which improved after two weeks. There was no statistically significant difference in the incidence of adverse reactions between the two groups (P=0.197).@*Conclusion@#BTX-A intraocular facial muscle injection can significantly improve the depressive symptoms of PD patients, and the effect lasts for a long time, with low incidence of side effects and high safety, which can be considered as a safe and effective new method for PD patients with depressive symptoms.

RESUMEN
Objective To investigate the prevalence of restless legs syndrome (RLS) in peritoneal dialysis patients and analyze the related risk factors.Methods This study was a cross-sectional study.The patients receiving maintenance peritoneal dialysis from January 2017 to December 2017 in the Peritoneal Dialysis Center of the Second Hospital Affiliated to Soochow University were selected as the study subjects.RLS was screened for peritoneal dialysis patients by epidemiological field investigation based on the RLS diagnostic criteria of the International Restless Leg Syndrome Research Group in 2014.Clinical data and laboratory examinations of selected patients were collected and the differences of clinical indicators between RLS and non-RLS patients were compared.The risk factors related to RLS were analyzed by logistic regression.Results Seventy-six cases of RLS were screened out from 396 PD patients.The prevalence of RLS was 19.2％.Compared with non-RLS group,RLS group patients had longer dialysis age,less 24 hours urine volume,and elevated blood intact Parathormone (iPTH) and alkaline phosphatase (AKP) (all P ＜ 0.05).There was no significant difference in primary disease ratio,sex,age,body mass index,blood pressure,hemoglobin,creatinine,urea nitrogen,uric acid,ferritin,serum iron,transferrin saturation,blood calcium,blood phosphorus,total cholesterol,triglyceride,low density lipoprotein,high density lipoprotein,eGFR,Kt/V,Ccr between RLS and non-RLS group patients (all P ＞ 0.05).Multivariate logistic regression analysis showed that long dialysis age (OR=1.010,95％CI 1.001-1.018,P=0.022) and high blood AKP (OR=1.005,95％CI 1.001-1.010,P=0.021) were independent risk factors for RLS in peritoneal dialysis patients (both P ＜ 0.05).Conclusions The prevalence of RLS is high in peritoneal dialysis patients.Long dialysis age and high blood AKP are independent risk factors for RLS.
RESUMEN
Objective To investigate the effects of metabotropic glutamate receptor 5 antagonist methyl-6-ethynyl-pyridine (MPEP) on behavior and striatal postsynaptic density-95 (PSD-95) protein expression changes in rats with levodopa-induced dyskinesia (LID).Methods Hemi-parkinsonian rat models were established by stereotaxically injection of 6-hydroxy dopamine (6-OHDA) in the right medial forebrain bundle;then,these 32 Parkinson's disease (PD) rats were randomly divided into four groups (n=8):levodopa (L-DOPA) treatment group,receiving L-DOPA 25 mg/kg+benserazide 6.25 mg/kg;saline group,giving the same volume of saline;MPEP treatment group,receiving 1.5 mg/kg MPEP;and L-DOPA+MPEP treatment group,accepted L-DOPA 25 mg/kg+benserazide 6.25 mg/kg+MPEP 1.5 mg/kg;All rats received intraperitoneal injections twice daily and continued for 21 days.At days 2,9,11,18 and 21,behavior changes of all rats were detected;the protein and mRNA levels of PSD-95 in striatal tissues were detected by Western blotting and real-time PCR,respectively.Results (1) Abnormal involuntary movement scores were significantly decreased in rats of L-DOPA+MPEP treatment group (42.33±12.43,41.80±13.69 and 40.30±9.76) as compared with those in L-DOPA treatment group (55.56±9.28,54.89±7.01 and 58.44±7.68) on days 11,18,and 21 (P＜0.05).Forepaw adjusting steps were significantly increased in Parkinson rats of L-DOPA+MPEP treatment group as compared with rats of L-DOPA treatment group (P＜0.05);and the increased extent was not decreased as time prolonging.Forepaw adjusting steps were also increased after MPEP treatment alone.Co-administration of L-DOPA with MPEP reversed the shortening of rotational response duration induced by L-DOPA.(2) The up-regulation of PSD-95 protein and mRNA levels in the lesioned striatum was noted in the L-DOPA treatment group (1.39 ±0.37 and 3.80 ±1.09),while this trend could be alleviated by coadministration of L-DOPA with MPEP (0.76±0.66 and 1.65±0.81).Conclusion MPEP can alleviate abnormal involuntary movements induced by L-DOPA and strengthen the anti-parkinsonian effect of L-DOPA,which may be related to regulation of striatal PSD-95 expression induced by L-DOPA.
RESUMEN
Objective To study the behavioural changes and biological effects of selective adenosine A2A receptor antagonist (CSC) in a rat model of levodopa(L-DOPA) -induced dyskinesia (LID).Methods The hemi-parkinsonian rat model was produced by stereotaxically injecting 6-OHDA to the right medial forebrain bundle. Rats were randomly divided into 4 treatment groups with a random number generating program to receive intraperitoneal injections twice daily for 21 days (n = 10): saline, L-DOPA at 25 mg/kg with benserazide at 6. 25 mg/kg, CSC at 2. 5 mg/kg alone and CSC at 2.5 mg/kg with L-DOPA at 25 mg/kg plus benserazide at 6. 25 mg/kg. Forepaw adjusting steps, abnormal involuntary movements (AIM) and rotational response duration were observed on 2, 9, 11,18 and 21 d. After sacrifice, the expression of adenosine A2A R and mGluR5 was observed by Western blot. Results Co-administration of LDOPA with CSC significantly increased the forelimb adjusting steps of parkinsonian rats during 21 days of treatment when compared to L-DOPA alone. CSC treatment alone increased the forelimb adjusting steps significantly. Co-administration of L-DOPA with CSC ( ( 11 ± 5 ) score) significantly decreased the AIM scores of limb and orolingual muscles when compared to L-DOPA alone (( 17 ± 4) score; t = 2. 44, P ＜0. 05). The subchronic L-DOPA treatment upregulated the striatal expression of adenosine A2A R and mGluR5. However, co-administration of L-DOPA with CSC reversed the shortening of the rotational motor response duration induced by L-DOPA administration during the period of the treatment and attenuated the LDOPA-induced upregulation of adenosine A2A R and mGluR5 expressions. Conclusions CSC improves motor function in a hemi-parkinson rat model, potentiates the antiparkinsonian effects with L-DOPA and partly attenuates LID. Co-administration of L-DOPA with CSC reverses the L-DOPA-induced upregulated expression of A2A R and mGluR5, indicating the involvement of both A2A R and mGluR5 in the onset and progression of LID. Adenosine A2AR antagonists may be promising drugs for treatment of LID.
