ObjectiveTo investigate the material basis of homologous and heterogeneous effect of Aurantii Fructus Immaturus（AFI） and Aurantii Fructus（AF） based on the total statistical moment analysis and molecular connectivity index（MCI）. MethodRelevant literature at home and abroad and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP） were consulted to establish the chemical composition database of AFI and AF， and set up their fingerprints by ultra-high performance liquid chromatography（UPLC）， and the total statistical moments and similarity parameters of the fingerprint were calculated. According to MCI， all components of AFI and AF were divided into different component groups， the average values of 0-8th order（0χ-8χ） MCI of the common component groups of AFI and AF were calculated. ResultThe values of total zero-order moment（AUCT） of AFI and AF were （10.57±2.45）×106， （5.09±0.89）×106 μV·s， the values of total first-order moment（MCRTT） were （11.57±1.58）， （12.10±1.29） min， the values of total second-order moments（VCRTT） were（24.49±2.30）， （26.49±2.54） min2， respectively. It showed that qualitative and quantitative parameters of AFI and AF were significantly different. The components with high similarity such as neohesperidin， hesperidin and narirutin were screened as the common potential pharmacodynamic components of AFI and AF. The non-common components of AFI， such as alysifolinone and imperatorin， and the non-common components of AF， such as neoeriocitrin and isosakuranin， with high similarity were screened out as potential heterogeneous components of AFI and AF. The composition groups of AFI and AF were classified into six categories， and the similarities between the composition groups of AFI and AF and the total constituents were 0.872-0.979 and 0.918-0.997， the average values of 0χ-8χ MCI of alkaloids in AFI and AF were 3.65 and 3.14， the average values of 0χ-8χ MCI of flavonoids were 8.47 and 8.47， the average values of 0χ-8χ MCI of volatile oils were 2.71 and 3.48， respectively. It showed that there were some differences in MCI of chemical constituents（groups） between AFI and AF. ConclusionThe chemical constituents（groups） of AFI and AF not only differ in content and species， but also in structural characteristics and structure-activity relationship， which can provide a basis for further explaining the scientific connotation of homologous and heterogeneous effect of AFI and AF.

Core stability training applying the sling exercise therapy pattern can significantly improve the balance of stroke survivors / 中华物理医学与康复杂志

Objective:To observe the impact of core stability training in the sling exercise therapy pattern on the balance of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a control group ( n=30) and an experimental group ( n=30). In addition to routine rehabilitation training, the control group received traditional core stability training, while the experimental group underwent core stability training applying the sling exercise therapy pattern. Before and after 4 weeks of training, the standing balance of both groups was evaluated using the Prokin balance trainer, with the length and area of motion recorded when performing the balance test with the eyes open and closed. Surface electromyography was used to record the average EMG (AEMG) values of the bilateral erector spinae and multifidus muscles during the balance testing. Results:After the 4 weeks of training the length and the area of progression of the center of the pressure were both significantly smaller for both groups than before the training with the eyes both open and closed. The average length and area in the experimental group were significantly less than among the controls. The AEMG values recorded during the balance tests were significantly higher than those before the intervention for both groups, with the multifidus muscle averages on the affected side significantly greater in the experimental group than among the controls when performing the balance test with the eyes closed.Conclusion:Core stability training in the sling exercise therapy pattern is superior to conventional core stability training because it can better improve the balance of stroke survivors.

Discussion on Material Basis of Different Parts of Mulberry with Different Effects Based on Molecular Connectivity Index / 中国实验方剂学杂志

ObjectiveTo explore the material basis for the difference in the efficacy of different parts of mulberry based on molecular connectivity index （MCI）. MethodBy referring to the relevant literature at home and abroad and traditional Chinese medicine systems pharmacology database and analysis platform （TCMSP） database， the chemical composition database of mulberry-source medicinal materials was established. Venn analysis was carried out on the components among mulberry-source medicinal materials. The components in the database were divided into 10 categories， and the composition information was analyzed. According to MCI value， all components of mulberry-source medicinal materials were divided into different groups. The angle cosine method was used to calculate the MCI similarity. The average MCI values of the common component group from 0-8 orders and CI of mulberry-source medicinal materials were calculated. ResultThe components with high similarity such as （+）-cycloolivil， 1′-methoxy-2′-hydroxydihydromollugin， kuwanon， morusin and 1-deoxynojirimycin were selected as potential pharmacodynamic components. Mulberry-source medicinal materials could be divided into five component groups. The similarity between component groups and total components was 0.760-0.999， and the similarity between component groups was 0.248-0.999. In Mori Ramulus， Mori Folium， Mori Cortex and Mori Fructus， the average MCI values of their flavonoids from 0-8 orders were 4.57， 4.59， 6.41， 4.24， respectively. The average MCI values of alkaloids from 0-8 orders were 2.65， 4.55， 2.58， 2.78， respectively. The average CI values from 0-8 orders were 5.51， 5.49， 5.44 and 2.88， respectively. ConclusionIt is preliminarily concluded that there are differences in the flavonoids and pathways of hypoglycemic effects between Mori Cortex and the other three mulberry-source medicinal materials. The MCI values of alkaloids from 0-8 orders in Mori Folium and Mori Fructus were higher， but their inhibitory activity of α-glucosidase were lower than those of Mori Ramulus and Mori Cortex. The structural characteristics of the total components of Mori Fructus represented by CI were quite different from the other three mulberry-source medicinal materials.

Lokomat training can significantly improve the walking ability of stroke survivors with lower limb spasm / 中华物理医学与康复杂志

Objective:To explore the effect of Lokomat training on the walking ability of stroke survivors with lower limb spasm.Methods:Eighty stroke survivors with lower limb spasm were randomly divided into an observation group and a control group, each of 40. Their routine rehabilitation treatment included normal limb positioning, passive joint movement, turnover training and inclined bed standing training. In addition, the control group underwent flat-ground walking training, while the observation group was given Lokomat training 3 times a week for 8 weeks. Both groups were evaluated after 4 and 8 weeks of treatment in terms of their walking ability, degree of lower limb spasm, lower limb motor functioning, balance and ability in the activities of daily life.Results:After 4 and 8 weeks the number of patients walking independently was significantly greater in the observation group. Their average stride frequency, step length on the affected side, support phase time and proportion of weight borne on the affected side were all significantly better than the control group′s averages. At both time points significantly more patients of the observation group had normal lower limb muscle tone. The observation group′s average Fugl-Meyer score, Berg Balance Scale score and modified Barthel Index score had improved significantly compared with those before the treatment, and were significantly better than the control group′s averages at the same time point. After 8 weeks of treatment the average walking speed of the observation group was faster than that of the control group.Conclusions:Lokomat training can significantly improve the walking ability of stroke survivors with lower limb spasm in the short term. Longer-term training can consolidate the effect and further improve the walking speed, motor function in the lower limbs, balance and even facility in daily life activities, as well as relieving spasm.

The effects of using a walking support band on the gait of stroke survivors / 中华物理医学与康复杂志

Objective:To evaluate the effect of using a walking support band on the gait of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a walking support band group ( n=20), an ankle foot orthosis (AFO) group ( n=20) and a conventional rehabilitation group ( n=20). All three groups received conventional rehabilitation therapy, while the AFO group members were additionally provided with an ankle-foot orthosis and the walking support band group members received training wearing a walking support band. Before and after 4 weeks of treatment, all three groups were evaluated using three-dimensional gait analysis. Results:A total of 57 patients finished the study. After the interventions, the average step speed, frequency and step length of the three groups had all increased significantly, while the average stride width, the percentage of double stance phase, unaffected and affected side stance phase, and the ratio between unaffected and affected side stance phase had all decreased significantly. After the intervention, the average step speed, frequency and length of the AFO and walking support band groups had increased significantly compared with the conventional rehabilitation group, while the average stride width of the AFO group, and the stride width, the percentage of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly. After the treatment, the average percentages of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly more than in the AFO group.Conclusions:A walking support band can significantly improve the abnormal gait of stroke survivors and is superior to an ankle-foot orthosis when combined with conventional rehabilitation therapy.

The timing of muscle activation in walking after a stroke / 中华物理医学与康复杂志

Objective To observe among stroke survivors the timing of muscle activation at the stance phase during walking using the surface electromyography ( sEMG) combined with 3D gait analysis. Methods Twenty stroke survivors assessed as at Brunnstrom stages Ⅲ, Ⅳ and Ⅴ were assigned to groups designated Ⅲ, Ⅳ and V. sEMG and 3D gait analysis were used to assess the activation timing of the bilateral rectus femoris ( RF) and biceps femoris ( BF) , the tibialis anterior ( TA) and the gastrocnemius medialis ( GM) . The activation timing and the dura-tion of activation of the muscles were compared among the 3 groups, as well as with those of healthy muscles. Results The onset time of the RF on the affected side was significantly later than on the healthy side, while that of the GM was significant earlier. The durations of BF and GM activation on the affected side were significantly shorter than on the unaffected side in group III. The onset times of the TA and GM on the affected side were significantly ear-lier than on the healthy side in group IV, as was the onset time of the TA of the affected side in group V. The average RF and BF onset times on the affected side in group Ⅳ were significantly earlier than in group Ⅲ. The onset time of the TA on the unaffected side and the average BF onset time on the affected side in group Ⅴ were significantly later than in group IV. The onset time of the RF and TA on the unaffected side in group Ⅳ and the onset time of the GM on the affected side were significantly later than in group III, while the onset time of the BF and TA on the affected side was significantly earlier. The average duration of BF activation on the unaffected side in group Ⅳ was significant-ly shorter than that of group Ⅲ. The average duration of TA activation on the unaffected side in group Ⅴ was signifi-cantly shorter than that of group IV. The duration of RF activation on the affected side in group Ⅴ was significantly shorter than that in group Ⅲ, and the same was true of the RF, BF, TA and GM activation times on the healthy side. Conclusions There are significant differences in the onset and duration of muscle activation when stroke survivors at different stages of recovery walk. Some muscles are activated too early and others are over-activated. These abnormali-ties gradually disappear with the recovery of motor function.
