Objective:To observe the effect of early weightbearing after anterior cruciate ligament reconstruction (ACLR) on lower limb motor function, activation of the knee muscles and the stability of the knee joint.Methods:Forty-four persons who had received ACLR were divided at random into a control group and an experiment group, each of 22. In addition to conventional rehabilitation treatment after surgery, the control group underwent weightbearing training from the 8th day after the surgery, while the experimental group began weight-bearing training from the 3rd postoperative day. Both groups had their motor functioning evaluated using the International Knee Scoring Committee (IKDC) knee subjective evaluation form 3 days after the operation, and then 6 and 12 weeks later. Their pain perceptions were quantified on the same schedule using visual analogue scoring (VAS), and protractor measurements documented active range of motion (AROM). Electromyography (AEMG) of the medial head and rectus femoris muscle was also performed, and the stability of the knee joint was assessed using the KT-1000 test.Results:After the intervention, the average IKDC score, VAS score, knee extension and flexion AROMs, medial quadriceps head AEMG ratio, and rectus femoris muscle AEMG ratio improved to different degrees in the two groups. At 6 weeks the average pain score, knee extension and flexion ranges of motion, quadriceps medial head AEMG ratio, and rectus femoris AEMG ratio of the experimental group were all better than the control group′s averages. At 12 weeks the average IKDC subjective knee function score in the experimental group was also superior.Conclusions:Supplementing conventional rehabilitation with early weight-bearing can significantly improve the recovery from anterior cruciate ligament reconstruction. Beginning on day 3 after the operation gives the best results.

Isochrysis galbana is considered an ideal bait for functional foods and nutraceuticals of humans because of its high fucoxanthin(Fx)content.However,multi-omics analysis of the regula-tory networks for Fx biosynthesis in I.galbana has not been reported.In this study,we report a high-quality genome assembly of I.galbana LG007,which has a genome size of 92.73 Mb,with a contig N50 of 6.99 Mb and 14,900 protein-coding genes.Phylogenetic analysis confirmed the monophyly of Haptophyta,with I.galbana sister to Emiliania huxleyi and Chrysochromulina tobinii.Evolutionary analysis revealed an estimated divergence time between I.galbana and E.huxleyi of～133 million years ago.Gene family analysis indicated that lipid metabolism-related genes exhibited significant expansion,including IgPLMT,IgOAR1,and IgDEGS1.Metabolome analysis showed that the content of carotenoids in I.galbana cultured under green light for 7 days was higher than that under white light,and β-carotene was the main carotenoid,accounting for 79.09％of the total carotenoids.Comprehensive multi-omics analysis revealed that the content of β-carotene,antheraxanthin,zeaxanthin,and Fx was increased by green light induction,which was significantly correlated with the expression of IgMYB98,IgZDS,IgPDS,IgLHCX2,IgZEP,IgLCYb,and IgNSY.These findings contribute to the understanding of Fx biosynthesis and its regulation,pro-viding a valuable reference for food and pharmaceutical applications.

Objective To observe the effects of vestibular function training and proprioception training on vertigo and balance function after postoperative circulatory ischemia under the visual participation. Methods From June, 2016 to May, 2018, 72 patients with posterior circulation ischemic vertigo aged more than 60 were randomly divided into proprioception group (n = 24), vestibular group (n = 24) and comprehensive group (n = 24). All the patients received routine medicine and rehabilitation training. Moreover, the proprioception group accepted proprioception training, the vestibular group accepted vestibular function training, and the comprehensive group accepted both proprioception training and vestibular function training. They were assessed with Dizziness Assessment Rating Scale (DARS), Dizziness Handicap Inventory (DHI) and Berg Balance Scale (BBS) before and after four weeks of treatment, while the mean velocity (Vm) of blood flow in the basilar artery was measured with transcranial Doppler, and the stability index (ST) was measured with Tetrax. Results The scores of DARS, DHI and BBS, and Vm and ST improved in all the groups after treatment (t > 57.825, P < 0.001). However, the scores of DHI and BBS, and ST improved more in the comprehensive group than in the proprioception group and the vestibular training group (P < 0.05), Vm and score of DARS improved more in the vestibular group and the comprehensive group than in the proprioception group (P < 0.05). Conclusion With the participation of the vision, vestibular function training combined with proprioception training can further alleviate vertigo caused by postoperative circulatory ischemia, and improve balance and quality of life.

Objective To observe the effect of Kinesio Taping with lattice shapes on pregnancy-related low back pain (PLBP). Methods From March, 2017 to April, 2018, 56 patients with PLBP were randomly divided into the control group (n = 28) and experimental group (n = 28). Both groups received the core stability training, while the experimental group accepted Kinesio Taping with lattice shapes additionally. They were assessed with Visual Analogue Scale (VAS), Roland-Morris Dysfunction Questionnaire (RMDQ), range of lumbar activity and torso angle before, three days and two weeks after treatment. Results The range of lumbar activity improved significantly in both groups (t > 6.327, P < 0.01) three days after treatment, while the scores of VAS and RMDQ, and the torso angle improved significantly in the experimental group (t > 4.862, P < 0.001). The scores of VAS and RMDQ, the range of lumbar activity, and the torso angle improved significantly in both groups two weeks after treatment (P < 0.001), and improved more in the experimental group than in the control group (P < 0.05). Conclusion Kinesio Taping with lattice shapes combined with core stability training can further reduce the lower back pain and improve the function for the PLBP patients.

Objective: To observe the clinical efficacy of the Mulligan technique in treating cervical vertigo (CV) in a hyperbaric oxygen (HPO) environment. Methods: Sixty-eight CV patients were randomly divided into a control group and an observation group, each of 34. Both groups were given routine treatment with ultrashortwave irradiation, but the observation group was additionally provided with 15 minutes of treatment based on the Mulligan technique in an environment with oxygen at 0.2 MPa, five days a week for two weeks. Both groups were assessed using the cervical vertigo symptoms and functional assessment scale (ESCV) and the daily frequency of vertigo was recorded before the treatment and 2, 4, 7, 14 and 60 days after treatment began. Moreover, the mean blood flow velocity in the patients′ vertebral (VA) and basilar arteries (BA) was detected using transcranial Doppler sonography before the treatment and after two weeks and two months. Results: There were no significant differences between the two groups in any of the measurements before the intervention. Afterward, however, significant improvement in all of the measurements was observed compared with before the treatment. After two weeks and two months the average ESCV score, daily occurrence of CV and mean VA and BA blood flows in the observation group were all significantly superior to those of the control group at the same time points. Conclusion Treatment based on the Mulligan technique in an environment with 0.2 MPa partial pressure of oxygen is a more effective way to relieve the symptoms of cervical vertigo and reduce the frequency of its occurrence. Such treatment is worthy of application in the clinic.
