To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding.A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle.A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P0.05).The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients.

Background. More and more evidence-based medicine has proved that Parkinson’s disease (PD) patients of tremor-dominant (TD) and postural instability and gait difficulty (PIGD) subtype express great individual differences and heterogeneity. Early identification of different subtypes may be an important way to delay disease progression and improve patients’ prognosis. Objective. The study aimed to compare the spectrum of motor symptoms (MS) and nonmotor symptoms (NMS) between TD and PIGD dominant in the early and middle stages of PD, and determine predictive factors that are associated with different motor subtypes. Methods. 292 PD patients in this study were divided into TD-PD and PIGD-PD, and the clinical characteristics between different motor subtypes were compared based on scales related to sleep, mood, and autonomic function. Univariate and multivariate ordered logistic regression analyses were used to analyze the independent influencing factors of disease severity between different motor subtypes. Through the establishment of binary logistic regression model, the potential independent risk factors for distinguishing TD-PD and PIGD-PD were studied. Results. Compared with TD subtype, patients with PIGD subtype have longer course of disease, higher disease severity, and higher daily dosage of levodopa. The severity of nontremor motor symptoms in PIGD-PD is greater than that of TD subtype. Only PIGD score was independently associated with disease severity for the two motor subtypes. Meanwhile, high scores (LED, total UPDRS, PIGD score, gastrointestinal, thermoregulatory, RBDSQ) and low tremor scores were the potential independent risk factors for distinguishing PIGD-PD from TD-PD. Conclusion. Specific nonmotor symptoms (RBD, gastrointestinal function and thermoregulation function) were associated with the PIGD subtype. Prompt detection and early treatment of NMSs related to the PIGD subtype based on the treatment of motor symptoms may improve patient outcomes.

Pingchan granule (PCG) is a traditional Chinese medicine for Parkinson's disease (PD).This was the first study aiming to evaluate the efficacy and safety of PCG for motor symptoms, gait impairments and quality of life in PD.In this multicenter, randomized, double-blind, placebo-controlled trial, 292 participants were included and followed for 9 months, randomly assigned at a 1:1 ratio to receive PCG or placebo. The primary outcome was the severity of motor symptoms assessed by Movement Disorder Society Unified Parkinson's Rating Scale III (MDS-UPDRS-III) motor score. Secondary outcomes included timed up and go test (TUG), functional gait assessment (FGA), freezing of gait (FOG), and quality of life assessed by Parkinson's disease questionnaire (PDQ-39). Assessments were done at baseline (T0), 3 months (T1), 6 months (T2) and 9 months (T3).Chinese Clinical Trial Register, ChiCTR-INR-1,701,194.Generalized estimating equation analyses revealed that PCG group had significantly better improvement in MDS-UPDRS-III motor score than placebo group, as well as its domain scores of axial symptoms, bradykinesia, rigidity, and tremor. Improvements of TUG time, FGA, FOG questionnaire (FOGQ), and PDQ39 scores were also observed.PCG had a long-lasting efficacy for motor symptoms and function in PD with good tolerance, supporting that PCG might be a viable alternative in the management of PD.

Sleep disorders are common non-motor symptoms in patients with Parkinson’s disease (PD). The characteristics and impact of multiple comorbid sleep disorders remain to be elucidated. Our goal was to investigate the characteristics of various sleep disorder comorbidities, and their association with motor complications and the impact on the quality of life in PD patients. In this multicenter, observational, cross-sectional study, data concerning the clinical characteristics of complicated sleep disorders were collected from PD patients treated at 40 different hospitals in Shanghai. Sleep disorders were evaluated using the PD Sleep Scale-2, Epworth Sleepiness Scale, Rapid Eye Movement Sleep Behavior Disorder Questionnaire-Hong Kong, and the International Restless Legs Scale. Among the 1006 subjects evaluated, 77.53% exhibited signs of sleep disorders, and most had multiple sleep disorders (n = 502, 49.9%). A smaller percentage of patients with sleep disorders had a single disorder (n = 278, 27.6%). Furthermore, an increased number of sleep disorders, including nighttime problems, excessive daytime sleepiness, rapid eye movement sleep behavior disorder, and restless legs syndrome was a significant contributor to a poor quality of life (β = 4.33, CI: 3.33–5.33, P for trend β = 0.355, 95% boot CI: 0.134, 0.652).Our study showed that a large proportion of PD patients suffer from multiple comorbid sleep disorders, which greatly decreases the quality of life in PD patients and is partially mediated by motor complications.

Potential benefits and risks of early (≤30 days from stroke onset) selective serotonin reuptake inhibitors (SSRIs) treatment for neurologic functional recovery after stroke are not fully understood.We searched PubMed, Embase, and the Cochrane Library to identify randomized controlled trials that assessed SSRI medications during the initial ictus after stroke versus placebo. Primary outcome was decrease in National Institutes of Health Stroke Scale (NIHSS) score. Secondary outcomes included the improvement of Barthel index, functional independence (modified Rankin Scale score 0-2 at the end of follow-up), the incidence of depression, and adverse events including diarrhea, insomnia, hepatic enzyme disorders, seizure, and intracranial hemorrhage. We used fixed effects models or random effects models to estimate weighted mean differences (WMDs) and relative risks (RRs) with 95% confidence intervals (CIs) according to heterogeneity.Eight trials were included, with 1549 patients. Compared with placebo, decrease in NIHSS was greater in SSRI-treated patients (WMD, 0.82; 95% CI, 0.31-1.33; P = .002). Trial sequential analysis showed that the cumulative z curve crossed the trial sequential monitoring boundary for benefit, establishing sufficient and conclusive evidence. Early SSRI treatment also promoted Barthel index (WMD, 5.32; 95% CI, 1.65-8.99; P = .005) and functional independence (RR, 2.54; 95% CI, 1.82-3.55; P .0001). There was no difference in the incidence of depression and adverse events between groups. No evidence of publication bias was detected.The early SSRIs treatment reduces the defective neurologic function in patients undergoing rehabilitation after stroke.

Characters of water delivery in winter of long distance canal system were analyzed and studied. Ice disasters threatening the operation safety such as ice jam and ice dam were introduced. Then a detailed summary of water delivery mode in winter was done to avoid ice disasters, and the mode of delivering water under a juxtaposed ice cover was recommended. At last operation and control of long distance canal system by stages in winter was proposed.

To explore the feasibility and therapeutic effect of thinned posterior tibial artery free perforator flap for the reconstruction of soft tissue defects at dorsum of hands.Six fresh adult lower limbs specimens were injected with red latex via arterial cannula and dissected. The number, distribution, branches, and outer diameter of posterior tibia artery perforators were observed. Based on the anatomic study, the perforator flaps were designed to reconstruct soft tissue defects at dorsum of hands and wrists. The redundant fat on the flaps was removed, but preserving the nutrient vascular system. 11 flaps were used with the size ranging from 2 cm x 5 cm to 10 cm x 14 cm.43 skin perforators of posterior tibial artery were observed in six lower limbs, 29 perforators with the outer diameter is greater than 0.5 mm when they threading over the deep fascia plane, on average every 4.8 bundles of sides. The mean outside diameter of perforating artery is (1.8 +/- 0.5) mm, and the length is (44 +/- 15) mm. 6 perforators were founded both in the second and fifth zone which could be used for anastomosis for its better diameters. All flaps survived completely without any complication at donor sites. 7 cases were followed up for 3-12 months. Both satisfactory functional and cosmetic results were achieved with a soft and thinned appearance.The thinned posterior tibial artery free perforator flap has a reliable blood supply and good appearance. It is very suitable for the reconstruction of small or medium-sized defects at the dorsum of hands and wrists.
