Electroacupuncture Improves Insulin Resistance in Type 2 Diabetes Mice by Regulating Intestinal Flora and Bile Acid.

Introduction: Adjusting internal organs and dredging channel electroacupuncture has a definite effect on type 2 diabetes, but the specific mechanism still needs to be further clarified. This study aims to investigate the effects of electroacupuncture on the gut microbiota and bile acids in db/db mice after the intervention of "adjusting internal organs and dredging channel" and further explore its mechanism of action in treating T2DM. Methods: We used db/db mice as the animal model and db/m mice from the same litter as the blank control group, a total of 4 weeks of intervention were conducted. We evaluated the effectiveness of the "adjusting internal organs and dredging channel" treatment by detecting indicators related to glucose and lipid- metabolism. Detect changes in the gut microbiota of mice in each group using 16SrDNA sequencing technology. The content of bile acids in mouse feces was determined using liquid chromatography mass spectrometry, and the correlation analysis between different bile acids and differential bacterial communities was performed. The expression levels of TGR5 and GLP-1 proteins were measured using the Western blot method. Results: Adjusting internal organs and dredging channel electroacupuncture can improve blood glucose levels in db/db mice, increase the abundance of Firmicutes and Actinobacteria, and increase the content of fecal bile acid pool heavy CA and UDCA. At the same time, it also increased the content of TGR5/GLP1 in the small intestine. Conclusion: Adjusting internal organs and dredging channel electroacupuncture can improve the disorder of glucose and lipid metabolism in db/db mice, regulate the abundance and colony composition of intestinal microbiota in mice, and regulate bile acid metabolism in mice. The interaction between bile acid and intestinal microbiota can also be observed; Mutual influence may play a role in regulating blood sugar together.

Acupuncture combined with Tuina in the treatment of cervical longus tendinitis: A case report.

INTRODUCTION: Cervical longus tendonitis is a type of disease with neck pain as the main clinical manifestation. Because the front of the cervical longus muscle is adjacent to the esophagus and pharynx, this disease is often accompanied by pharyngeal pain and pain when swallowing. Clinical and imaging doctors often have an incomplete understanding of it, and this disease is often confused with other diseases that cause neck pain. PATIENT CONCERNS: A 33-year-old Chinese woman was the patient. Suffering from severe neck pain and significantly limited activity, accompanied by left shoulder pain, occasionally dizziness, headache and other symptoms, the pain is significantly aggravated when doing swallowing action. DIAGNOSIS: Tendonitis of the long neck muscle. INTERVENTIONS: Given the patient's condition, we used acupuncture combined with massage therapy as a symptomatic treatment. OUTCOMES: After 10 days of treatment, the symptoms were better than before, and no pain was seen in the swallowing movements such as drinking water (Fig. 2C and D). LESSONS: Because the clinical reports of diseases are rare, the treatment methods are limited, and acupuncture combined with massage is an effective method for the treatment of tendonitis of the cervical long muscle, to dredge the meridians, promoting blood circulation, removing blood stasis and relieving pain.

Acupuncture is an effective therapy for macular damage: A case report.

RATIONALE: Many factors can contribute to the development of macular injury, which results in vision loss as a result of a disease. Heredity, age, underlying eye illness, internal eye surgery, or eye trauma can all cause it. A safer alternative to current therapies for macular degeneration is urgently needed since they all induce ocular irritation and postoperative recurrence as well as a host of other adverse effects. PATIENT CONCERNS: A 12-year-old girl was the patient. A laser pen burnt her right eye. There was a spot and a shadow in the middle of her right eye's visual field. DIAGNOSES: Macular degeneration. INTERVENTIONS: Given the patient's age, we opted out of medicine and instead used acupuncture as a symptomatic treatment. OUTCOMES: Two months after therapy concluded, optical coherence tomography result report indicate that the macula region of the right eye is better than it was previously. The corrected visual acuity of the right eye recovered from 0.25 to 1.0, and the clinical accompanying symptoms of the right eye disappeared. LESSONS: No additional medication or surgical procedure was employed in this instance. We treated the macular damage with acupuncture, which relieved the patient's clinical symptoms and had no adverse effects. This demonstrates that acupuncture may be beneficial in treating ophthalmopathy in this direction.

Study on acupuncture improving sleep deprivation comorbid with cognitive dysfunction based on rs-fMRI: A protocol for systematic review and meta-analysis.

BACKGROUND: Sleep deprivation often lead to changes in attention, memory, mood, alertness, and metabolism. Especially, it is often accompanied by cognitive impairment of the brain. Acupuncture is safe and effective for improving cognitive function, but its underlying mechanism is not fully understood. Resting-state functional magnetic resonance imaging is an important means to study brain activity changes. However, the results are inconsistent and lack systematic evaluation and analysis. METHODS: We will search 9 databases, including PubMed, EMBASE, EBSCOhost-Medline, Web of Science, Cochrane Library, China National Knowledge Infrastructure, VIP Database and Wan-Fang Database, Chinese Biomedical Literature Database, and 2 clinical trials register platforms: Chinese Clinical Trial Registry, ClinicalTrials.gov (www.ClinicalTrials.gov/) from inception to November 1, 2022. We will use the Review Manager 5.4 software provided by the Cochrane Collaborative Network for statistical analysis. We then assessed the quality and risk of the included studies and observed the outcome measures. RESULTS: This study will analyze the effect of acupuncture on brain activity changes, improvement of sleep duration, and cognitive impairment. CONCLUSION: This meta-analysis aims to investigate the efficacy of acupuncture on brain activity changes in sleep deprivation comorbid with cognitive dysfunction, so as to provide effective evidence for clarifying its pathogenesis.

Acupuncture plus Tuina for chronic insomnia: A protocol of a systematic review and meta-analysis.

BACKGROUND: Insomnia is a common sleep disorder. It refers to a subjective feeling of dissatisfaction with sleep duration and quality that affects social functioning, even though there are appropriate opportunities and environments for sleep. The disease for a long time can easily cause physical and mental fatigue, anxiety, depression, and other symptoms. Anxiety, depression, and insomnia can worsen the condition. Acupuncture and Tuina therapy has been widely used in the treatment of chronic insomnia, and this study aimed to conduct a meta-analysis of acupuncture plus Tuina in the treatment of chronic insomnia to clarify its efficacy. METHODS: The following databases will be searched: Web of Science, PubMed, Cochrane Library, Embase, and Medline databases. In addition, we will also collect 4 databases of China: China National Knowledge Infrastructure, China Biomedical Literature Database, VIP Database, and Wan-fang Database. We selected eligible studies published up to October 2021. We used Review Manager 5.4, provided by the Cochrane Collaborative Network for statistical analysis. Clinical randomized controlled trials related to acupuncture plus Tuina for chronic insomnia were included in this study. Language is limited to both Chinese and English languages. Study selection, data extraction, and study quality assessment were independently performed by 2 researchers. We then assessed the quality and risk of the included studies and observed the outcome indicators. RESULTS: This study provides a high-quality synthesis to assess the effectiveness and safety of acupuncture plus Tuina for treating chronic insomnia. CONCLUSION: This systematic review will provide evidence to determine whether acupuncture plus Tuina is an effective and safe intervention for patients with chronic insomnia. ETHICS AND DISSEMINATION: The protocol of the systematic review does not require ethical approval because it does not involve humans. This article will be published in peer-reviewed journals and presented at relevant conferences. REGISTRATION NUMBER: INPLASY2021100115.

An iterative optimization method for estimating accelerometer bias based on gravitational apparent motion with excitation of swinging motion.

Field calibration is an important method to guarantee the accuracy of a strapdown inertial navigation system. Zero velocity update based on the zero-velocity constraint when the carrier is without translational motion is a typical system-level calibration method. In zero velocity update, there is a coupling between biases and horizontal misalignment angles. The accuracy of horizontal misalignment angles is determined by the equivalent accelerometer biases in horizontal directions, which means that improving the accuracy of horizontal angles needs accurate calibration of accelerometer biases. Meanwhile, alignment with gravitational apparent motion is widely used taking advantages of its alignment ability in a swinging condition. But it is an analytical method and cannot calibrate sensor biases and is always dealt as a coarse alignment method. In order to calibrate accelerometer biases and utilize advantages of the alignment method with gravitational motion, a method to estimate accelerometer biases based on an iterative optimization method and gravitational apparent motion is presented in this paper. First, accelerometer biases are introduced to calculate apparent acceleration and an objective function is constructed. Then, Newton's iteration is applied to iteratively optimize the parameters describing gravitational apparent motion and accelerometer biases. As revealed by the theoretical analysis and experimental results, different patterns of gravity and accelerometer biases will be generated when the carrier exhibits a swinging motion; thus, the convergence of the proposed algorithm will be ensured. After accelerometer biases are removed, initial alignment performed with the gravitational apparent motion reconstructed by the estimated parameters gives nearly zero horizontal misalignment angles.
