  • 脑深部电刺激对帕金森病认知功能的影响

    【摘要】帕金森病(Parkinson’s disease, PD)是中老年人常见的神经系统变性疾病。脑深部电刺激(deep brain stimulation, DBS)可以改善中晚期或药物难治性PD患者的运动症状、生活质量,并且丘脑底核脑深部电刺激(subthalamic nucleus deep brain stimulation, STN DBS)还可减少术后多巴胺能药物的治疗剂量,但DBS术后同时可出现认知功能、行为、情绪和精神等方面的变化。目前DBS对认知功能如语言功能、执行功能、记忆力、注意力、视功能和精神运动速度等方面的影响尚无一致的结论,现就DBS对认知功能各方面的影响进行综述。

  • Design and implementation of postoperative evaluation pipeline of deep brain stimulation by multimodality imaging

    Deep brain stimulation (DBS) surgery is an important treatment for patients with Parkinson's disease in the middle and late stages. The accuracy of the implantation of electrode at the location of the nuclei directly determines the therapeutic effect of the operation. At present, there is no single imaging method that can obtain images with electrodes, nuclei and their positional relationship. In addition, the subthalamic nucleus is small in size and the boundary is not obvious, so it cannot be directly segmented. In this paper, a complete end-to-end DBS effect evaluation pipeline was constructed using magnetic resonance (MR) data of T1, T2 and SWI weighted by DBS surgery. Firstly, the images of preoperative and postoperative patients are registered and normalized to the same coordinate space. Secondly, the patient map is obtained by non-rigid registration of brain map and preoperative data, as well as the preoperative nuclear cluster prediction position. Then, a three-dimensional (3D) image of the positional relationship between the electrode and the nucleus is obtained by using the electrode path in the postoperative image and the result of the nuclear segmentation. The 3D image is helpful for the evaluation of the postoperative effect of DBS and provides effective information for postoperative program control. After analysis, the algorithm can achieve a good registration between the patient's DBS surgical image and the brain map. The error between the algorithm and the expert evaluation of the physical coordinates of the center of the thalamus is (1.590 ± 1.063) mm. The problem of postoperative evaluation of the placement of DBS surgical electrodes is solved.

  • Effect of deep brain stimulation on depression of Parkinson’s disease: a network meta-analysis

    Objective To assess the changes in depression symptoms in patients with Parkinson’s disease (PD) receiving combined treatment of deep brain stimulation (DBS) and antiparkinsonian drug therapy (DT) compared with under DT alone. Methods Related literature was retrieved from electronic databases, including PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Data, and VIP databases. Stata 14.0 software was used for statistical analysis. Network meta-analysis was performed using frequentist model to compare different interventions with each other. Results Five cohort studies and seven randomized controlled trials (RCTs) were included. The total number of participants was 1241. Assessed by the Beck Depression Inventory (BDI) score as the primary outcome, patients who received DT alone showed worse outcome in depression as compared to those who received subthalamic nucleus (STN)-DBS plus DT [standardized mean difference (SMD)=0.30, 95% confidence interval (CI) (0.01, 0.59), P<0.05], and there was no significant difference between the patients receiving globus pallidus interna (GPi)-DBS plus DT and those receiving STN-DBS plus DT [SMD=–0.12, 95%CI (–0.41, 0.16), P>0.05] or those receiving DT alone [SMD=–0.42, 95%CI (–0.84, 0.00), P>0.05]. Assessed by BDI-Ⅱ as the primary outcome, patients who received DT alone showed worse outcome in depression than those who received STN-DBS plus DT [SMD=0.29, 95%CI (0.05, 0.54), P<0.05]; compared with STN-DBS plus DT and DT alone, GPi-DBS plus DT was associated with better improvement in depression [SMD=–0.26, 95%CI (–0.46, –0.06), P<0.05; SMD=–0.55, 95%CI (–0.88, –0.23), P<0.05]. The ranking results of surface under the cumulative ranking curves showed that DBS plus DT had a better superiority in depression symptoms, and GPi-DBS was better than STN-DBS. Conclusion Compared with DT, STN-DBS plus DT is more likely to improve the depressive symptoms of PD patients, and GPi-DBS may be better than STN-DBS.

  • Nursing analysis of 7 cases with Tardive dyskinesia treated by deep brain stimulation

    ObjectiveTo explore the best nursing regimen for patients with severe Tardive dyskinesia (TD) after deep brain stimulation (DBS). MethodsTo analyze the clinical nursing data of 7 patients with TD treated by DBS in our department from January 2018 to August 2019, preoperative assessment of the patient's condition, dyskinesia care, psychological care, preoperative preparation, preoperative guidance, etc. General nursing, observation and nursing of complications, psychological nursing, safety management and rehabilitation training of limb function were carried out after operation discharge to discharge guidance, daily life guidance, DBS device-related education and other post-discharge continuous care to help patients improve quality of life. The changes of TD symptoms were assessed with the abnormal involuntary movement scale -LRB-AIMS, the nursing effect was assessed with the psychiatric nursing observation sc-Nosiee (NOSIE) , and the self-care ability was assessed with the ability of daily livin-ADL- scale (ADL). ResultsAll of the 7 TD patients recovered well after operation, without complications caused by improper nursing, and the TD symptoms were relieved. The AIMS and NOSIE scores were significantly lower at 1 month, 3 months and 1 year after operation than those before operation (P<0.05). The ADL scores were significantly higher than those before operation (P<0.05). ConclusionIn order to treat TD patients with DBS operation, we should pay attention to the pertinent nursing in perioperative period and the continuous nursing after discharge, it is of great significance to relieve the symptoms of involuntary movement, improve the mental state and improve the self-care ability of patients with TD.
