Finger tapping test is a common testing item for patients with Parkinson's disease (PD) in clinical neurology. It mainly evaluates the fine motor function of patient's hand in three aspects:amplitude, speed and regularity of the movement. This paper focused on the quantitative assessment of regularity of finger tapping movement for PD patients. The movement signals of thumb and index finger were recorded by using inertial sensor unit in the process of tapping test. Two nonlinear dynamic indexes, approximate entropy (ApEn) and sample entropy (SampEn), were calculated, and then the values were statistically analyzed. The experimental results indicated that both indexes had significant differences between patient group and control group. Moreover, the indexes had relatively high correlation with the scores of corresponding unified Parkinson's disease rating scale (UPDRS) item rated by clinical clinician, which illustrated that these two indexes could reflect the injury level of the repetitive finger movement. So, as a reliable method, it can be provided to the clinical evaluation of hand movement function for PD patients.
ObjectiveTo analysis the regularity of prescriptions of Chinese Medicine for syndrome of intense fire and heat (syndrome of Shi-Re-Huo-Du), and to provide evidences for the clinical treatment.MethodsCNKI, Sinomed, WanFang Data, VIP and Chinese medical databases were electronically searched to collect literatures about traditional Chinese Medicine for syndrome of Shi-Re-Huo-Du from inception to October, 2018. Two reviewers independently screened literature and extracted data. Then BICOMS 2 software was used to generate the co-occurrence matrix, NetDraw software was used to draw network maps.ResultsA total of 381 literatures involving 335 patients were included. There were 716 prescriptions of Shi-Re-Huo-Du (390 Chinese medicinal herbs), in which the frequently used herb included radix glycyrrhizae (346), Scutellariae Radix (255), Fructus Gardeniae (241), Rehmanniae Radix (239), Moutan Cortex (218), etc. The classification was performed according to traditional efficacy, Qing-re herbs (73), Bu-xu herbs (47), and Hua-tan-zhi-ke-ping-chuan herbs (39), accounted for 40.77% of the total herbs. The results of the analysis showed that the top herbs in Degree and Betweenness were consistent with high-frequency herbs. Among them, Rehmanniae Radix, Fructus Gardeniae, Scutellariae Radix, Moutan Cortex are the most important traditional Chinese herbs. High-frequency herbs are mainly based on Qing-re herbs, and the highest frequency of the herbs combination is Scutellariae Radix-Fructus Gardeniae.ConclusionAlthough there are kinds of herbs for syndrome of Shi-Re-Huo-Du, the commonly used herbs are relatively concentrated, and there is obvious interaction between high-frequency herbs, which is in line with the principle of compatibility of Chinese medicine. The high-frequency Chinese herbs and herb pairs were main components of the Chinese patent medicines and classic prescription. It reflected the rule of medicine used and essence in the treatment of syndrome of Shi-Re-Huo-Du.
ObjectiveTo observe the changes of the inner-retinal irregularity index (IRII) of eyes with idiopathic macular epiretinal membrane (IMEM) before and after surgery and its correlation with visual function.Methodsretrospective series of studies. From March 2017 to May 2018, 46 IMEM patients (46 eyes) diagnosed in the Department of Ophthalmology of Central Theater Command General Hospital were included in the study. BCVA, visual deformation degree (M), OCT inspection with swept source were all performed. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into logMAR visual acuity for record. The average IRII was 1.255±0.048, the average logMAR BCVA was 0.63±0.21, the average M value was 0.68±0.38, the average of central macular thickness (CMT) was 353.57±73.92 μm, the average inner retinal layer thickness (IRT) was 181.50±40.91 μm. The complete and incomplete ellipsoid zone (EZ) were 17 and 29 eyes, respectively. All eyes underwent a 25G three-incision closed vitrectomy through the flat part of the ciliary body, and the epiretinal membrane and inner limiting membrane were removed at the same time. The changes of IRII, M value, BCVA, CMT, IRT and EZ were observed at 1, 3, 6, and 12 months after surgery, and the correlation were analyzed between IRII and M value and BCVA before and after surgery. Single-factor repeated measurement data analysis of variance was used for the comparison of BCVA, M value, CMT, and IRT before and after surgery. Spearman rank correlation analysis were adopted for the correlation analysis between IRII and BCVA, M value, CMT, IRT and EZ integrity before and after surgery.ResultsTwelve months after surgery, the average IRII and logMAR BCVA were 1.175±0.032 and 0.47±0.16, respectively. Compared with those before surgery, they were significantly improved, and the difference was statistically significant (F=22.273, 5.453; P＜0.001, ＜0.001). The average M value (F=20.109), CMT (F=14.273), IRN (F=13.665) were significantly lower than those before the operation, and the difference was statistically significant (P＜0.001, 0.001, ＜0.001). The integrity of EZ was significantly improved compared with that before surgery, and the difference was statistically significant (χ2=12.715, P＜0.001). The results of correlation analysis showed that preoperative IRII was positively correlated with preoperative M value and CMT (r=0.951, 0.701; P＜0.001, ＜0.001). It was positively correlated with postoperative M value, logMAR BCVA, CMT and EZ integrity (r=0.650, 0.369, 0.720, 0.293; P＜0.001, ＜0.001, P=0.048). It was not correlated with preoperative logMAR BCVA and EZ integrity (r=0.283, 0.001; P=0.056, 0.996).ConclusionThe IRII of IMEM eyes before surgery is significantly correlated with the BCVA and M values after surgery.
