[Retrospective cohort study on application of acupuncture-aided anesthesia technique to patients undergoing thoracoscopic lobectomy].

OBJECTIVE: To compare the clinical effect of "initial scheme" and "improved scheme" of acupuncture-aided anesthesia for patients undergoing thoracoscopic lobectomy. METHODS: A retrospective analysis about 2 groups ("initial scheme" and "improved scheme") of patients (40 cases in each group) who underwent thoracoscopic lobectomy was conducted in the present paper. Patients of the "initial scheme" group received thoracoscopic operation with three incisions under acupuncture-aided anesthesia i.e., electroacupuncture (EA) stimulation of bilateral Hegu (LI4), Neiguan (PC6), Houxi (SI3) and Zhigou (SJ6), combined with Lidocaine and ropivacaine epidural anesthesia and propofol intravenous anesthesia from January of 2013 to December of 2017. Patients of the "improved scheme" group received thoracoscopic operation with single incision under acupuncture-aided anesthesia by EA, combined with ropivacaine paravertevinal block and lidocaine and remifentanil intravenous anesthesia from August 2018 to August 2021. The incidence of intraoperative deep breathing, resuscitation time, ambulatory rate on day after surgery and postoperative incision pain of the two schemes were compared. RESULTS: The incidence of intraoperative deep breathing and the degree of postoperative incision pain were significantly lower (P<0.05), the postoperative resuscitation time was obviously shorter (P<0.05), and the ambulatory rate on day after surgery was higher (P<0.05) in the "improved scheme" group than in the "initial scheme" group. CONCLUSION: The "improved scheme" is better than the "initial scheme" in stabilizing the patient's breathing during thoracoscopic lobectomy operation, shortening the resuscitation time, and ameliorating the postoperative recovery state and pain reaction, thus being a better technical solution in clinical practice.

[Progress of the application research of modern acupuncture anesthesia in perioperative period of thoracic surgery].

Modern acupuncture anesthesia is the application of acupuncture-related therapies to optimize the perioperative management which is based on the combined acupuncture-medicine anesthesia technology, and building a perioperative acupuncture anesthesia accelerated rehabilitation system. Based on the thoracic surgery, this paper analyzes and summarizes the application effects of modern acupuncture anesthesia, focusing on preoperative anxiety relief and advanced analgesia； reduce the dosage of anesthetics, stable respiration and hemodynamics, anti-stress and organ protection during surgery； postoperative analgesia, prevention of nausea, vomiting and cognitive impairment, improvement of gastrointestinal function, prevention of cognitive impairment, and enhancement of immunity. It is anticipated that this review may provide a basis for the further promotion and application of modern acupuncture anesthesia in clinical practice.

[Effect of electroacupuncture pretreatment on differential expression profiles of myocardial long non-coding RNA and mRNA in mice with myocardial ischemia-reperfusion injury].

OBJECTIVE: To observe the effect of electroacupuncture (EA) pretreatment at "Neiguan" (PC6) on expression profiles of myocardial long non-coding RNAs (LncRNAs) and mRNAs in myocardial ischemia-reperfusion injury (MIRI) mice, so as to explore its mechanisms underlying prevention of MIRI via regulating LncRNA expression. METHODS: C57BL/6 mice were randomly divided into sham, model, and EA groups (n=4 in each group). The MIRI model was established by occlusion of the anterior descending branch (ADB) of the left coronary artery for 30 min, followed by reperfusion for 24 h. In the sham group, the ADB was only threaded beneath the artery without ligation. EA was applied to bilateral PC6 for 30 min prior to ischemia induction. Surgery was performed within 30 min at the end of EA stimulation. The expression profiles of differentially expressed LncRNAs and mRNAs in the left ventricular myocardium were analyzed by using LncRNA microarray. RESULTS: There was a significant diffe-rence in the expression pattern of LncRNAs and mRNAs among the sham, model and EA groups. A total of 1 693 LncRNAs and 2 858 mRNAs between the model and sham groups, and 3 859 LncRNAs and 1 343 mRNAs between the EA and model groups were identified to be differentially expressed candidates. According to Venn intersection analysis, LncRNAs with opposite regulative orientations in the model and EA groups were screened and defined as EA-related LncRNAs. LncRNA-mRNA co-expression analysis and Gene Ontology enrichment analysis of the EA-related LncRNAs predicted their roles to regulating post-traumatic stress and repairing of myocardial cells. Meanwhile, the proteins' function encoded by EA-related mRNAs mainly involved post-traumatic stress and inflammatory regulation. CONCLUSION: EA pretreatment at PC6 acupoint can produce extensive regulation on myocardial LncRNAs and mRNAs in MIRI mice, suggesting an involvement of LncRNAs in EA pretreatment induced improvement of MIRI. These results may provide direction and molecular basis for subsequent in-depth studies to reveal the underlying mechanisms of EA pretreatment for MIRI.

[Research on Acupuncture in Regulating the Inflammatory Reaction in Anti-ischemia-reperfusion Injury].

The inflammatory response during ischemia-reperfusion is one of principal reasons for secondary organ injury. Therefore, the inhibition of inflammation has become a research hot spot. The current research showed that acupuncture can not only directly inhibit the infiltration of inflammatory cells and regulate the expression of inflammatory cytokines, but is also involved in the overall regulation of the inflammatory signaling pathway and inhibition of the inflammatory response, thereby effectively improving ischemia-reperfusion injury. Here, we review research on the mechanism of acupuncture in ischemia-reperfusion injury via regulation of the inflammatory response.
