Inhibitory effects of ß-asarone on lncRNA BACE1-mediated induction of autophagy in a model of Alzheimer's disease.

The primary aim of this study was to examine the correlation between the formation of Aß plaques and autophagy, which is regulated by ß-asarone and the lncRNA BACE1-AS. Additionally, the study sought to explore potential targets of the drug in inhibiting the deposition of toxic AD-related proteins and restoring impaired mitochondrial and autophagic functions. SHY5Y cells were utilized to construct a stable Alzheimer's disease (AD) model, followed by the utilization of interference and overexpression lentiviruses targeting BACE1-AS to establish a cell model. The cells were categorized into five groups, including a normal group, siRNA/BACE1 group, and ß-asarone group. The fluorescence quantitative PCR technique was employed to assess the disparity in BACE1 mRNA expression, while changes in immunofluorescence (IF) were observed to determine the stable interference titre and action time of the lentiviruses. Additionally, western blotting (WB) and fluorescence quantitative PCR were employed to evaluate the expression of proteins and mRNAs associated with AD and autophagy. The findings demonstrated a significant elevation in BACE1 expression levels in brain tissue among individuals with AD compared to those without the condition. Moreover, the results indicated that the introduction of ß-asarone led to an increase in the expression of the BACE1-AS gene in the cell group transfected with plasmid H12732. Furthermore, it was observed that ß-asarone enhanced the expression levels of shRNA and BACE1 after 72 h. In contrast, ß-asarone suppressed the expression of PS1, Aß, BACE1, APP, and p62, while promoting the expression of syn, LC3 I/II, and Beclin-1. Based on these findings, it can be concluded that ß-Asarone exerts a comprehensive influence on the expression of proteins associated with AD and synaptic function. ß-Asarone exhibits the potential to mitigate Aß deposition by impeding the expression of lncBACE1, thereby facilitating autophagy through the suppression of BACE1's inhibitory impact on autophagy. This complements the self-enhancing effect of autophagy.

[ZHUANG Li-xing's experience in treatment of dyskinesia of Parkinson's disease with acupuncture at triple-acupoint prescription].

The paper introduces professor ZHUANG Li-xing's clinical experience in treatment of dyskinesia of Parkinson's disease with acupuncture at triple-acupoint prescription. In pathogenesis, dyskinesia of Parkinson's disease refers to yang deficiency and disturbing wind. In treatment, acupuncture focuses on warming yang, promoting the circulation of the governor vessel, regulating the spirit and stopping trembling; and Baihui (GV 20), Suliao (GV 25) and Dingchanxue (Extra) are selected to be "trembling relief needling". In combination with Jin's three needling, named "three-trembling needling" "three-governor-vessel needling" and "three-spasm needling", the triple-acupoint prescription is composed. To ensure the favorable therapeutic effect, this prescription is modified according to the symptoms and the specific techniques of acupuncture are combined such as conducting qi, harmonizing yin and yang, and manipulating gently for reinforcing and reducing.

Sanfu herbal patch applied at acupoints in patients with bronchial asthma: study protocol for a randomized controlled trial.

BACKGROUND: Bronchial asthma is one of the most common inflammatory airway disorders. As one of the main non-drug therapies, the Sanfu herbal patch (SHP) has been widely used to treat bronchial asthma, although the evidence for its efficacy and associated mechanism are inconclusive. The objective of this trial is to clarify the clinical efficacy and safety of the SHP in the treatment of bronchial asthma in the chronic persistent or clinical remission stage and to provide high-quality data for further research. METHODS: We propose a multicentre, double-blinded, parallel, randomized, placebo-controlled clinical trial involving 4 study hospitals in China. A total of 72 eligible participants will be randomized into an SHP group and a placebo group. They will receive an SHP for 3 treatment sessions. The primary outcome will be changes in forced expiratory volume in 1 s after 3 treatment sessions. Secondary outcomes will include the following: (1) the Asthma Quality of Life Questionnaire, Asthma Control Test, and Asthma Long-term Follow-up Scale; (2) levels of Metallothionein-2 and Transgelin-2 in blood and urine; and (3) levels of IL-5, IL-13, IL-23, IL-25, and thymic stromal lymphopoietin in blood. Analysis of the data will be performed at baseline, at the end of the 2nd and 3rd treatment sessions, and at the 24-week follow-up. The safety of the SHP will be evaluated at each treatment session. DISCUSSION: The aims of this trial are to determine whether the SHP is more effective than placebo in the treatment of patients with bronchial asthma, as well as whether the SHP works by reducing airway inflammation and reversing bronchoconstriction.

[Vascular cognitive impairment with no dementia treated with auricular acupuncture and acupuncture:a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy on vascular cognitive impairment with no dementia (VCIND) between the combined therapy of auricular acupuncture and acupuncture and the simple acupuncture. METHODS: One hundred patients of VCIND were randomized into a combined therapy of auricular acupuncture and acupuncture group (a combined therapy group) and an acupuncture group, 50 cases in each one. The basic internal medicine treatment was applied in the two groups. Additionally, in the combined therapy group, auricular acupuncture and JIN's three needling therapy were used. pizhixia (AT4), xin (CO15), shen (CO10), gan (CO12), erzhong (HX1) were selected in auricular acupuncture, once every Monday, Wednesday and Friday; Niesanzhen, Zhisanzhen and Sishenzhen were selected in JIN's three needling therapy, once a day. In the acupuncture group, JIN's three needling therapy was just provided, once a day. The treatment was given for 4 weeks in the two groups. Montreal cognitive assessment (MoCA) and social function activities questionnaire (FAQ) were adopted for the evaluation comparison before treatment and in 2 weeks and 4 weeks after treatment in patients of the two groups. RESULTS: Compared with those before treatment, the total scores of MoCA were improved in 2 and 4 weeks after treatment in the two groups (all P<0.01). The score in the combined therapy group was improved more apparently as compared with that in the acupuncture group (P<0.01). FAQ score was reduced in the two groups (all P<0.05). The score in the combined therapy group was reduced more apparently as compared with that in the acupuncture group (P<0.05). As compared with the result in 2 weeks of treatment, MoCA score was improved in the two groups in 4 weeks of treatment (both P<0.01), the improvements in the combined therapygroup were more obvious than those in the acupuncture group (P<0.05) and FAQ score was reduced in the two groups (P<0.05), but the difference was not significant between the two groups (P>0.05). CONCLUSIONS: The combined therapy of auricular acupuncture and acupuncture effectively improve the cognitive function and social function, which are better than the effects of simple acupuncture in VCIND. The improvement of the combined therapy in social function is more advantageous in the treatment of the first two weeks.

[Post-stroke shoulder-hand syndrome treated with floating-needle therapy combined with rehabilitation training: a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy in the treatment of post-stroke shoulder-hand syndrome between floating-needle therapy and conventional acupuncture on the basis of rehabilitation training. METHODS: One hundred cases of post-stroke shoulder-hand syndrome were randomized into a floating-needle group and an acupuncture group, 50 cases in each one. The passive and positive rehabilitation training was adopted in the two groups. Additionally, in the floating-needle group, the floating-needle therapy was used. The needle was inserted at the site 5 to 10 cm away from myofasical trigger point (MTrP), manipulated and scattered subcutaneously, for 2 min continuously. In the acupuncture group, the conventional acupuncture was applied at Jianqian (EX-UE), Jianyu (LI 15), Jianliao (TE 14), etc. The treatment was given once every two days, 3 times a week, and 14 days of treatment were required. The shoulder hand syndrome scale (SHSS), the short form McGill pain scale (SF-MPQ) and the modified Fugl-Meyer motor function scale (FMA) were used to evaluate the damage severity, pain and motor function of the upper limbs before and after treatment in the two groups. The clinical efficacy was compared between the two groups. RESULTS: SHSS score, SF-MPQ score and FMA score were improved significantly after treatment in the two groups (all P < 0.01), and the improvements in the floating-needle group were superior to those in the acupuncture group (all P < 0.05). The total effective rate was 94.0% (47/50) in the floating-needle group, which was better than 90.0% (45/50) in the acupuncture group (P < 0.05). CONCLUSION: The floating-needle therapy combined with rehabilitation training achieves a satisfactory efficacy on post-stroke shoulder-hand syndrome, which is better than the combined therapy of conventional acupuncture and rehabilitation training.
