The paper reports acupuncture treatment for one case of oculomotor nerve palsy after cranial-orbital communicating tumor surgery. The acupoint prescription was composed of the local acupoints of the eyes (Yansanzhen, Tijian, Cuanzhu [BL2], Yuyao [EX-HN4] and Sizhukong [TE23]), the acupoints on the head, face and neck (Yangbai [GB14], Sibai [ST2] and Fengchi [GB20]), Guanyuan (CV4) on the abdomen, and those on the four limbs (Hegu [LI4], Zusanli [ST36], Shenmai [BL62] and Zhaohai [KI6]). The point-to-point needling technique with the eyelid lifted was operated at Tijian, Cuanzhu (BL2), Yuyao (EX-HN4), and Sizhukong (TE23). Warm needling with moxa cone placed on the needle handle was operated at Guanyuan (CV4) and Zusanli (ST36), and the usual needling technique was delivered at the rest acupoints. The treatment was given once daily, discontinued for 1 day after every 6 treatments. One course of treatment was composed of 7 days, and 6 courses were required. After treatment completion, the upper eyelids were basically symmetrical and the bilateral eye cracks were equal, the double vision appeared occasionally. No recurrence and no aggravation were reported in 1 month of follow up visit.

BACKGROUND: Hepatic inflammatory cell accumulation and the subsequent systematic inflammation drive acute-on-chronic liver failure (ACLF) development. Previous studies showed that the vagus nerve exerts anti-inflammatory activity in many inflammatory diseases. Here, we aimed to identify the key molecule mediating the inflammatory process in ACLF and reveal the neuroimmune communication arising from the vagus nerve and immunological disorders of ACLF. METHODS: Proteomic analysis was performed and validated in ACLF model mice or patients, and intervention animal experiments were conducted using neutralizing antibodies. PNU-282987 (acetylcholine receptor agonist) and vagotomy were applied for perturbing vagus nerve activity. Single-cell RNA sequencing (scRNA-seq), flow cytometry, immunohistochemical and immunofluorescence staining, and clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) technology were used for in vivo or in vitro mechanistic studies. RESULTS: The unbiased proteomics identified C-X-C motif chemokine ligand 9 (CXCL9) as the greatest differential protein in the livers of mice with ACLF and its relation to the systematic inflammation and mortality were confirmed in patients with ACLF. Interventions on CXCL9 and its receptor C-X-C chemokine receptor 3 (CXCR3) improved liver injury and decreased mortality of ACLF mice, which were related to the suppressing of hepatic immune cells' accumulation and activation. Vagus nerve stimulation attenuated while vagotomy aggravated the expression of CXCL9 and the severity of ACLF. Blocking CXCL9 and CXCR3 ameliorated liver inflammation and increased ACLF-associated mortality in ACLF mice with vagotomy. scRNA-seq revealed that hepatic macrophages served as the major source of CXCL9 in ACLF and were validated by immunofluorescence staining and flow cytometry analysis. Notably, the expression of CXCL9 in macrophages was modulated by vagus nerve-mediated cholinergic signaling. CONCLUSIONS Our novel findings highlighted that the neuroimmune communication of the vagus nerve-macrophage-CXCL9 axis contributed to ACLF development. These results provided evidence for neuromodulation as a promising approach for preventing and treating ACLF.

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

Objective:To exploring the value of MR neuroimaging for quantitative assessment of the facial nerve and peripheral lymph nodes in patients with acute peripheral facial paralysis. Methods:Based on a prospective experimental design, 32 patients with idiopathic peripheral facial palsy were enrolled in the experiment. Based on MR neuroimaging technology, MR high-resolution thin-layer images of bilateral facial nerves were acquired. The diameters of different segments of the bilateral facial nerve were measured, including the labyrinthine segment, the geniculate ganglion, the horizontal segment, the vertical segment, the stem-mammary foramen segment, the trunk of the parotid segment, the temporal trunk, and the cervical trunk, as well as the quantitative indicators of peri-auricular and parotid lymph nodes（number, length and diameter of the largest lymph nodes）. Differences in quantitative indices of nerve diameter and peripheral lymph nodes between the paraplegic and healthy sides were compared using the paired t-test and Wilcoxon signed rank test. Results:The diameter of geniculate ganglion, mastoid foramen stem, parotid main trunk, temporal facial trunk, and cervical facial trunk were notably increased on the facial paralysis side compared to the contralateral side（P<0.05）. However, no significant differences were observed in the diameter of labyrinthine segment, horizontal segment, or vertical segment compared to the contralateral side. There were significantly more periauricular lymph nodes on the facial paralysis side than the contralateral side（P=0.001）. Conclusion:MR neuroimaging enables the quantitative assessment of structural changes in the facial nerve of patients with acute peripheral facial paralysis, demonstrating nerve enlargement in the geniculate ganglion, stylomastoid foramen segment, main trunk of the parotid segment, temporal facial trunk, and cervical facial trunk. Additionally, an increased number of periauricular lymph nodes is observed on the affected side. These findings may aid clinicians in assessing the efficacy of treatments and predict the prognosis of these patients.

Objective:To explore the value of high resolution computed tomography（HRCT） combined with Magnetic Resonance Imaging（MRI） in the diagnosis of inner ear malformation. Methods:HRCT and MRI data of 82 patients with inner ear malformations were analyzed retrospectively. HRCT MPR and CPR reconstruction of the inner ear structure, facial nerve canal and oblique sagittal MRI reconstruction of the internal auditory canal were performed. The inner ear malformations were classified, the conditions of facial nerve canal and cochlear nerve were evaluated. The association between inner ear malformation and cochlear nerve dysplasia were analyzed by Chi-square test with continuity correction. Results:Among the 82 patients with inner ear malformations,there were 49 cases of bilateral symmetry, 11 cases of bilateral asymmetry and 22 cases of unilateral inner ear malformations. Respectively, the most prevalent types were IP-Ⅱ（42.96%）, dilatation of atrium aqueduct（18.31%） and malformations of atrium and semicircular canal 19.72%. Out of 50 cases of cochlear malformations,only 3 were isolated cochlear malformations, and the rest were accompanied by other malformations of varying degrees. In the 67 ears examined by MRI, 26（38.81%） had cochlear nerve deficiency（CND）, and the incidence of CND varied with different types of inner ear malformations. Out of 142 ears, 28（19.72%） had abnormalities of the facial nerve canal. Conclusion:HRCT combined with MRI can accurately distinguish the types of inner ear malformation and effectively evaluate the facial nerve canal and cochlear nerve, and further provides the important finger and Guide value for the clinician to formulate the reasonable treatment and the operation plan.

A 30-year-old female patient with a benign tumor in the superficial lobe of the left parotid gland underwent tumor resection via a 5 cm intra-hairline incision, using the da Vinci Xi surgical robot combined with the NIM-Response 3.0 facial nerve monitoring system. During the operation, facial nerve branches were located and protected through facial nerve monitoring, and the robotic arms were used for precise tumor dissection. Postoperatively, the facial nerve function, incision healing, and tumor recurrence were observed. duration of the procedure was 120 minutes, and the tumor（2.0 cm×1.5 cm） was completely resected. Postoperative pathological examination indicated a pleomorphic adenoma. During the 3-month postoperative follow-up, the patient's facial nerve function remained normal, no salivary fistula occurred, the incision was hidden within the hairline, no tumor recurrence was found in the ultrasound reexamination, and the patient was highly satisfied with the appearance. The surgical approach of robot-assisted resection of benign parotid gland tumor via a hairline incision under facial nerve monitoring has significant advantages in facial nerve protection and cosmetic effect, and is suitable for patients with benign parotid gland tumors meeting specific conditions.

Neurofibromas are benign peripheral nerve sheath tumors. It is more common in neurofibromatosis type Ⅰ. However, isolated vagal nerve neurofibroma（VNN） of the neck is extremely rare, and only a few case reports have been reported. Its etiology and pathogenesis are not clear. The diagnosis is mainly based on pathological examination and immunohistochemistry, and surgical resection is the main treatment. This study reports a rare case of giant solitary vagus neurofibroma in the neck. The patient was a 29-year-old female who was found to have a mass on the right side of the neck by physical examination, which was considered to be a vagus nerve tumor by neck ultrasound and imaging examination. The tumor was completely removed during the operation, with the size of about 10.0 cm×2.5 cm, and the patient had no special discomfort. Postoperative pathology and immunohistochemistry confirmed neurofibroma. After surgery, the patient had right vocal cord paralysis, hoarseness, choking and paroxysmal cough. After swallowing function training and voice rehabilitation treatment in the department, the patient recovered satisfactorily. There was no complication and recurrence during the follow-up of 1 year. This article reviews the literature to improve the diagnosis and treatment of solitary vagus neurofibroma in the neck by combining its medical history, imaging features, pathology and immunohistochemistry, and surgical treatment.

OBJECTIVE: The occurrence and development of atrial fibrillation (AF) are influenced by the autonomic nervous system and inflammation. Acupuncture is an effective treatment for AF. This study explored the protective effects of acupuncture in a rat model of paroxysmal AF and investigated its mechanisms. METHODS: Male Sprague-Dawley rats (n = 130) were randomly divided into blank control (Con), sham operation (Sham), AF, and acupuncture treatment (Acu) groups. A paroxysmal AF model was established by rapid atrial pacing through the jugular vein. Rats in the Acu group were immobilized to receive acupuncture treatment at Neiguan acupoint (PC6) for 20 min daily for seven days. The other groups were immobilized for the same duration over the treatment period but did not receive acupuncture. The AF induction rate, AF duration, cardiac electrophysiological parameters, and heart rate variability were evaluated by monitoring surface electrocardiogram and vagus nerve discharge signals. After the intervention, the rats were euthanized, and atrial morphology was assessed using haematoxylin and eosin staining. The expression of macrophage F4/80 antigen (F4/80) and cluster of differentiation (CD) 86 in atrial myocardial tissue was detected using immunohistochemistry, immunofluorescence and flow cytometry. The expression levels or contents of interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), α7 nicotinic acetylcholine receptor (α7nAChR), phosphorylated Janus kinase 2 (p-JAK2), and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in atrial myocardial tissue were detected using Western blotting, reverse transcription-quantitative polymerase chain reaction, or enzyme-linked immunosorbent assay. The role of α7nAChR in acupuncture treatment was verified by intraperitoneal injection of the α7nAChR antagonist methyllycaconitine (MLA). RESULTS: Compared with the AF group, acupuncture significantly reduced AF duration and induction rate, improved cardiac electrophysiology by enhancing vagus nerve activity and regulating autonomic balance. It also decreased the pro-inflammatory M1 macrophage proportion, alleviating myocardial injury and infiltration. MLA weakened acupuncture's electrophysiological improvement and anti-inflammatory effect. Results suggest that acupuncture triggers the α7nAChR-JAK2/STAT3 pathway and exerts cardioprotection via neuroimmune regulation. CONCLUSION Acupuncture significantly reduced the AF induction rate, shortened AF duration, improved cardiac electrophysiological parameters, enhanced vagus nerve activity, and decreased the expression of pro-inflammatory M1 macrophages and inflammatory factors in rats with paroxysmal AF. Its positive effects are related to the activation of the α7nAChR-mediated JAK2/STAT3 signalling pathway, indicating that the interaction between cardiac vagus nerve and macrophages may be a potential target for acupuncture in the prevention and treatment of AF.

OBJECTIVE

To describe the clinical presentation, management and outcome of a rare case of isolated oculomotor nerve palsy in an immunocompromised adult secondary to a central nervous system (CNS) tuberculoma.

This is a case report.

A Filipino male in his 30s developed severe throbbing headache followed by binocular diplopia and drooping of the right upper eyelid. Findings were compatible with a neurologically-isolated pupil-involving, complete oculomotor nerve palsy on the right. Brain magnetic resonance imaging demonstrated enlargement and contrast enhancement of the cisternal portion of the right oculomotor nerve. Serologic testing was positive for the human immunodeficiency virus (HIV) and syphilis. Cerebrospinal fluid (CSF) analysis showed lymphocytic pleocytosis and elevated protein. CSF polymerase chain reaction was positive for Mycobacterium tuberculosis (TB). The patient was treated with penicillin, quadruple anti-Koch’s, and anti-retrovirals. Eyelid position and ocular motility improved after treatment. Aberrant regeneration of the right oculomotor nerve was observed with elevation of the right eyelid on downgaze (pseudo-Graefe sign).

CNS tuberculoma may present as a neurologically-isolated oculomotor nerve palsy, particularly in immunocompromised individuals. In TB-endemic countries, like the Philippines, it should be considered in the differential diagnosis. Early recognition and appropriate antimicrobial therapy can lead to neurologic improvement.

OBJECTIVE: To explore the mechanism of electroacupuncture (EA) in promoting recovery of the facial function with the involvement of autophagy, glial cell line-derived neurotrophic factor (GDNF), and phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling pathway. METHODS: Seventy-two male Sprague-Dawley rats were randomly allocated into the control, sham-operated, facial nerve injury (FNI), EA, EA+3-methyladenine (3-MA), and EA+GDNF antagonist groups using a random number table, with 12 rats in each group. An FNI rat model was established with facial nerve crushing method. EA intervention was conducted at Dicang (ST 4), Jiache (ST 6), Yifeng (SJ 17), and Hegu (LI 4) acupoints for 2 weeks. The Simone's 10-Point Scale was utilized to monitor the recovery of facial function. The histopathological evaluation of facial nerves was performed using hematoxylin-eosin (HE) staining. The levels of Beclin-1, light chain 3 (LC3), and P62 were detected by immunohistochemistry (IHC), immunofluorescence, and reverse transcription-polymerase chain reaction, respectively. Additionally, IHC was also used to detect the levels of GDNF, Rai, PI3K, and mTOR. RESULTS: The facial functional scores were significantly increased in the EA group than the FNI group (P<0.05 or P<0.01). HE staining showed nerve axons and myelin sheaths, which were destroyed immediately after the injury, were recovered with EA treatment. The expressions of Beclin-1 and LC3 were significantly elevated and the expression of P62 was markedly reduced in FNI rats (P<0.01); however, EA treatment reversed these abnormal changes (P<0.01). Meanwhile, EA stimulation significantly increased the levels of GDNF, Rai, PI3K, and mTOR (P<0.01). After exogenous administration with autophagy inhibitor 3-MA or GDNF antagonist, the repair effect of EA on facial function was attenuated (P<0.05 or P<0.01). CONCLUSIONS EA could promote the recovery of facial function and repair the facial nerve damages in a rat model of FNI. EA may exert this neuroreparative effect through mediating the release of GDNF, activating the PI3K/mTOR signaling pathway, and further regulating the autophagy of facial nerves.
