Effect of Dynamic or Static Hand Action Observation on Chronic Non-fluent Aphasia after Stroke / 中国康复理论与实践

Objective:To compare the effects of observation to non-goal-oriented hand actions with video or pictures on speech recovery in stroke patients with chronic non-fluent aphasia. Methods:From January, 2016 to December, 2018, 30 patients with non-fluent aphasia after stroke were randomly divided into two groups. The control group (n = 15) repeated the verbs after watching picture, and the experimental group (n = 15) repeated the verbs after watching videos, for four weeks. They were assessed with Western Aphasia Battery (WAB) before treatment and every week after treatment. Results:Aphasia quotient (AQ) increased with time (F > 32.922, P < 0.001), but no significant difference was found between two groups at any time points (t < 0.699, P > 0.05). The interactive effect between time and group was significant (F = 6.398, P < 0.001), which suggested that AQ increased more in the experimental group than in the control group. Conclusion:For non-goal-oriented hand action observation, video observation maybe promote speech recovery in stroke patients with chronic non-fluent aphasia.

Effect of Structured Exercise Training on Old Patients with Chronic Kidney Disease Complicated with Sarcopenia / 中国康复理论与实践

Objective:To observe the clinical effect of low and medium intensity aerobic exercise combined with resistance exercise on patients with chronic kidney disease (CKD) complicated with sarcopenia. Methods:From 2018 to 2019, 11 elderly patients with CKD complicated with sarcopenia were enrolled in this study. All the patients received low and medium intensity aerobic exercise combined with resistance exercise intervention on the basis of regular internal medical treatment. Each exercise section included 30 to 50 minutes of aerobic exercise and 20 to 30 minutes of resistance exercise, and was conducted three times a week for twelve weeks. Before exercise, and 24 hours, six weeks and twelve weeks after exercise, the related indicators were measured. Results:No statistical difference in serum lipids and renal function indicators was found 24 hours after exercise, and six and twelve weeks post exercise (P > 0.05). Compared with pre-exercise condition, the reach in seat increased six weeks after exercise (P < 0.05); the appendicular skeletal muscle mass index, the grip strength index, the 6-meter walking speed, the peak oxygen uptake (VO2peak), the one-leg standing time and the reach in seat improved twelve weeks after exercise (P < 0.05). Compared with the results six weeks after exercise, the grip strength index, the 6-meter walking speed, VO2peak and the one-leg standing time improved twelve weeks after exercise (P < 0.05). Conclusion:Structured exercise training of low and medium intensity aerobic exercise combined with resistance exercise training would not worsen the renal function of patients with CKD complicated with sarcopenia; however, it could improve the muscle mass, strength and motor function of them.

Application of drug-target prediction technology in network pharmacology of traditional Chinese medicine / 中国中药杂志

In recent years, network pharmacology has been developed rapidly, and especially, the concept of ″network target″ has brought a new era in the field of traditional Chinese medicine (TCM). The integrity and systematicness emphasized in network pharmacology comply with the characteristics of holistic view and treatment in Chinese medicine. It can provide deeper insights into the underlying mechanisms of TCM theories, including the illustration on action mechanism of Chinese medicine, selection of pharmacodynamic materials and the combination principles of various Chinese herbs, etc. Therefore, this theory is more suitable for TCM academic characteristics and practical conditions. The key problem in network pharmacology is how to efficiently and quickly identify the interactions between large amounts of drugs and target proteins. As an efficient and high throughput way, drug-target prediction technology can reduce costs, quickly predict the component targets, and provide foundation for the application of TCM network pharmacology. In view of the large amount of compounds and target databases, different prediction methods and technologies have been developed, and used to predict the drug-target interactions. Many virtual screening technologies have been successfully applied to network pharmacology. Based on different prediction principles, drug-target prediction technology can be generally divided into four types： ligand-based prediction, receptor-based prediction, machine learning and combined prediction. In this paper, we are going to review the prediction methods of drug-target interactions and give acomprehensive elaboration of their application in network pharmacology of TCM, hoping to provide beneficial references for various Chinese medicine researchers.

Optimization of component compatibility of Naomaitong for anti-cerebral ischemia treatment based on artificial neural network / 中国药学杂志

OBJECTIVE: To optimize the component compatibility of Naomaitong for anti-cerebral ischemia treatment based on artificial neural network. METHODS: The five effective parts in Naomaitong were divided into ten groups by uniform design. Except the rats in the sham groups, all rats were subject to right middle cerebral artery occlusion (MCAO) with the suture-occluded method by Longa. The effect of Naomaitong was evaluated based on the bulk density of necrotic zone and infarction area percentage. The artificial neural network model was established for pharmacodynamic prediction. RESULTS: The model established in this study could predict the actions of different drug combinations. The best effect was obtained by the following formula: total anthraquinones of rhubarb (TAR) 180 mg·kg-1, total saponins of Ginseng (TSG) 70 mg·kg-1, total flavonoids of Pueraria (TFP) 450 mg·kg-1, total phenolic acid of Ligusticum wallichii (TPLW) 27 mg·kg-1, rhizome oil (RO) 110 μL·kg-1. CONCLUSION: Different compatibilities of Naomaitong are all effective for the treatment of ischemia in rats. Uniform design combined with ANN can be a more efficient method to realize dose optimization for Naomaitong prescription.
