Objective To investigate the protective effect of protocatechuic acid(PCA)on the PC12 cell model of Alzheimer’s disease(AD)and to explore its mechanism . Methods Amyloid beta peptide 1-42(Aβ1-42)fiber polymers were identified by immunofluorescence. After PC12 cells were stimulated with the Aβ1-42 fiber polymers, the cellular morphology was observed at different time points of hour 0, 3, 6, 9, 12, 24 , and the cellular viability was tested by methyl thiazolyl tetrazolium(MTT)assay to monitor the modeling condition. The effect of PCA on PC12 cells was detected after PC12 cells were pretreated with the different contentions of PCA. Autophagy-related marker Beclin1 protein level was detected by Western blotting method to investigate the protective mechanism of PCA. Results Aggregated white Aβ1-42 mass was stable at hour 12 and 24, and showed no significant difference between the two time points, the cell damage rate being 40%. Therefore, we defined culturing time being 12 and 24 hours as the modeling condition of AD model. The cell viability was increased with 200-800 μmol/L of PCA after culturing for 24 hours(P<0.01) , and the Western blotting results showed that the Beclin1 protein expression was up-regulated by PCA. Conclusion PCA prevents PC12 cells from Aβ1-42-induced toxicity, the mechanism being related with the increase of cellular autophagy.

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.

Tinosporae Radix, as a traditional Chinese medicinal herb, is the dried root tuber of Tinospora sagittata or T. capillipes. It was first recorded in the Compendium of Materia Medica Supplement in the Qing Dynasty and included in the previous edition of the Chinese Pharmacopoeia. Tinosporae Radix is excavated in autumn and winter and used after removing fibrous roots, washing, and drying. It is indicated for sore throat, carbuncle boils poison, waist and abdominal pain, and various heat syndromes and is commonly used to treat chronic inflammation. Its efficacy is significantly known as “broad-spectrum antibiotics in Zhuang medicine”. Tinosporae Radix is a traditional Chinese medicinal herb often taken by Zhuang and Yao nationalities in Guangxi province and has a wide range of application and development values and research significance. Modern studies have shown that Tinosporae Radix contains diterpenoids, alkaloids, sterols, anthraquinones, glycosides, fatty acids, volatile oils, and other compounds, which have many pharmacological activities such as anti-inflammatory and analgesic, antibacterial and antibacterial, antioxidant, anti-diabetic, and anti-tumor and anti-cancer effects, and it has achieved good efficacy in inhibiting inflammation and treating sore throat and other diseases. In recent years, there have been many research reports on the status, chemical constituents, pharmacological action, clinical application, and quality evaluation of Tinosporae Radix resources, but there is no systematic review and introduction at present. By consulting the literature and combining it with modern research, this paper systematically summarizes and collates Tinosporae Radix resources to provide guidance for the comprehensive development and utilization of Tinosporae Radix resources and subsequent in-depth study.
