[Interactive effects of irrigation regime and planting density on grain yield and water use efficiency in winter wheat]. / 灌水量与密度互作对冬小麦籽粒产量和水分利用效率的影响.

To get an optimal irrigation regime and planting density for simultaneous improvement of grain yield (GY) and water use efficiency (WUE) in winter wheat, we examined the responses of 'Tainong 18' (with bigger ears) and 'Shannong 22' (with medium-sized ears) under four irrigation regimes, including 0, 45, 60, and 75 mm. Those two cultivars were planted at four densities: Tainong 18 at 135×104, 270×104, 405×104, and 540×104 plants·hm-2 and Shannong 22 at 90×104, 180×104, 270×104, and 360×104 plants·hm-2. The interactive effects of irrigation regimes and plant densities on GY, water consumption characteristics, and WUE were investigated. The results showed that GY, evapotranspiration, soil water consumption, and WUE were significantly affected by irrigation regime, plant density, and their interaction. The optimal irrigation regime was 45 mm for both cultivars, while the optimal plant density was 405×104 plants·hm-2 for Tainong 18 and 270×104 plants·hm-2 for Shannong 22, as indicated by the highest GY, the lowest ratio of soil evaporation to evapotranspiration after jointing, and higher WUE and the ratio of soil water consumption below 1 m to total soil water consumption. The rational combination of plant density and irrigation could reduce unnecessary water consumption and improve WUE.

A protocol of systematic review and meta-analysis of Mozart's Music for drug-resistant epilepsy.

BACKGROUND: This study will aim to assess the effectiveness of Mozart's Music (MM) for the management of patients with drug-resistant epilepsy (DRE). METHODS: In this study, we will search MEDLINE, EMBASE, Cochrane Library, Web of Science, CINAHL, Chinese Scientific Journal Database Information, WANGFANG, and China National Knowledge Infrastructure from their inauguration to March 1, 2020 without language and publication time restrictions. We will also identify other literature resources, such as reference lists of any related reviews. Trial quality will be examined by Cochrane risk of bias tool; reporting bias will be identified by a funnel plot and Egger test; and statistical analysis will be undertaken by RevMan 5.3 software. RESULTS: This study will summarize high quality randomized controlled trials to appraise the effectiveness and safety of MM for the treatment of patients with DRE. CONCLUSIONS: The findings of this study will supply evidence to judge whether MM is effective on DRE at evidence-based medicine level. STUDY REGISTRATION NUMBER: CRD42020170512.

Rehabilitation training combined acupuncture for limb hemiplegia caused by cerebral hemorrhage: A protocol for a systematic review of randomized controlled trial.

BACKGROUND: Previous studies have reported that rehabilitation training combined acupuncture (RTA) can be used for the treatment of limb hemiplegia (LH) caused by cerebral hemorrhage (CH). However, its effectiveness is still unclear. In this systematic review study, we aim to evaluate the effectiveness and safety of RTA for LH following CH. METHODS: We will retrieve the databases of CENTRAL, EMBASE, MEDILINE, CINAHL, AMED, CBM, and CNKI from inception to March 1, 2019 with no language restrictions. The randomized controlled trials of RTA for evaluating effectiveness and safety in patients with LH following CH will be included. Cochrane risk of bias tool will be used to measure the methodological quality for all included studies. Two authors will independently select the studies, extract the data, and assess the methodological quality of included studies. A third author will be invited to discuss if any disagreements exist between 2 authors. If more than 2 eligible studies will be included, the outcome data will be pooled, and meta-analysis will be conducted if it is possible. RESULTS: This systematic review will assess the effectiveness and safety of RTA for LH caused by CH. The primary outcome includes limbs function. The secondary outcomes consist of muscle strength, muscle tone, quality of life, and any adverse events. CONCLUSION: The findings of this study will summarize the current evidence of RTA for LH caused by CH, and may provide helpful evidence for the clinical treatment. DISSEMINATION AND ETHICS: The results of this study will be published in peer-reviewed journals or will be presented on conference meeting. This work does not require ethic approval, because it will be conducted based on the published studies. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019120034.

[Stability of a winter wheat population with high yield and high resource use efficiency]. / å†¬å°éº¦é«˜äº§é«˜æ•ˆç¾¤ä½“çš„å¹´é™ é—´ç¨³äº§æ€§èƒ½.

Using the winter wheat cultivar Tainong 18 as the experimental material, we analyzed yield stability from 2012 to 2016 under three different treatments: T1(following typical local field management practices), T2(high-yield: high nitrogen and water were supplied to foster high grain yield), and T3(high-yield, high-efficiency: optimized field management including increasing plant density, reducing nitrogen input and delaying of the sowing date). Yield related phenotypic traits, including the number of ears on the main stem and tillers, leaf area index (LAI), photosynthetically active radiation (PAR) interception, dry matter accumulation and distribution, as well as grain yield, were analyzed over four seasons to determine their relationships with annual radiation, accumulated temperature and precipitation. We then determined grain yield stability for each of the three treatments. The amount and distribution of radiation, accumulated temperature, and precipitation varied greatly within each season. The ears on the main stem represented 38.9%, 58.7%, and 66.9% of the total ears, respectively, for wheat grown in the T1, T2 and T3 treatments, indicating that T1 ears originated mainly from the tillers, T2 ears from both the main stem and the tillers, and T3 ears from the main stem. The T2 and T1 treatments produced the highest and lowest amount of dry matter and grain yield, respectively. Although having relatively lower dry matter accumulation at maturity compared with T2, T3 led to higher grain yield due to high LAI, high PAR interception and utilization, high net canopy photosynthetic rate from booting (especially from 14 days after anthesis) to maturity and a higher harvest index. Among the three treatments, T3 resulted in the lowest annual range, standard deviation, and coefficient of variation for LAI, PAR interception, and dry matter accumulation. Thus, grain yield was most stable in wheat grown in the T3 treatment mainly due to stability in biological production during all four seasons.
