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.

Background and Objective:
Premature ventricular complex (PVC) burden exhibits one of three circadian types,
classified as fast-type, slow-type, and independent-type PVC. It is unknown whether PVC circadian types have
different heart rate variability (HRV) parameter values. Therefore, this study aimed to evaluate differences in HRV
circadian rhythm among fast-, slow-, and independent-type PVC.
Methods:
This cross-sectional observational study consecutively recruited 65 idiopathic PVC subjects (23 fast-,
20 slow-, and 22 independent-type) as well as five control subjects. Each subject underwent a 24-hour Holter to examine PVC burden and HRV. HRV analysis included components that primarily reflect global, parasympathetic, and sympathetic activities. Repeated measures analysis of variance was used to compare
differences in HRV circadian rhythm by PVC type. Results. The average PVC burden was 15.7%, 8.4%, and 13.6% in fast-, slow-, and independent-type idiopathic PVC subjects, respectively. Global, parasympathetic nervous system, and sympathetic nervous system HRV parameters were significantly lower in independenttype PVC versus fast- and slow-type PVC throughout the day and night. Furthermore, we unexpectedly found that tendency towards sympathetic activity dominance during nighttime was only in independent-type PVC.
Conclusion
The HRV parameters are reduced in patients with independent-type PVC compared to fast- and slowtype PVC. Future research is warranted to determine possible differences in the prognosis between the three PVC types.

The paper summarizes the academic thought and clinical experience of professor LI De-hua in treatment of facial nerve injury after total parotidectomy with blade needle based on jingjin (muscle region of meridian, sinew/fascia) theory. This disease is located at muscle regions of hand-/foot-three yang meridians; and the sinew/fascia adhesion is its basic pathogenesis, manifested by "transversely-distributed collaterals" and "knotted tendons". In treatment, the knotted tendons are taken as the points. Using the relaxation technique of blade needle, the lesions of sinews/fascia are dissected and removed to release the stimulation or compression to the nerves and vessels so that the normal function of sinews/fascia can be restored.

Parkinson's disease (PD) is a common neurodegenerative disease characterized by motor symptoms, including bradykinesia, resting tremor, and progressive rigidity. More recently, non-motor symptoms of PD, such as pain, depression and anxiety, and autonomic dysfunction, have attracted increasing attention from scientists and clinicians. As one of non-motor symptoms, pain has high prevalence and early onset feature. Because the mechanism of PD-related pathological pain is unclear, the clinical therapy for treating PD-related pathological pain is very limited, with a focus on relieving the symptoms. This paper reviewed the clinical features, pathogenesis, and therapeutic strategies of PD-related pathological pain and discussed the mechanism of the chronicity of PD-related pathological pain, hoping to provide useful data for the study of drugs and clinical intervention for PD-related pathological pain.

Philippine Journal of Otolaryngology Head and Neck Surgery 2023;38(1):50-53
Objective:
To discuss the case of a 36-year-old man who presented with left unilateral facial paralysis 11 days after mastoidectomy.
Methods:
Design: Case Report
Setting: Tertiary Government Training Hospital
Patient: One
Results:
A 36-year-old man with recurrent left ear discharge of 30 years duration underwent left canal wall-down mastoidectomy and was discharged well after 3 days. On follow up after 8 more days, he was noted to have House Brackmann IV left facial paralysis. Following 5 days methylprednisolone, neurologic evaluation and physical therapy rehabilitation, facial paralysis improved in the ensuing weeks until House-Brackmann I was achieved at week 12.
Conclusion
Delayed-onset Facial Palsy (DFP) following tympanomastoid surgery may be approached conservatively, including steroids, acyclovir, and, if with a history of herpes or varicella infection, immunization can be given. Prognosis for DFP is good especially when the facial nerve is identified intraoperatively during otologic surgeries

OBJECTIVE:
To explore the brain effect mechanism and the correlation between brain functional imaging and cognitive function in treatment of depressive disorder (DD) with transcutaneous auricular vagus nerve stimulation (taVNS) based on the resting-state functional magenetic reasonance imaging (rs-fMRI).
METHODS:
Thirty-two DD patients were included in a depression group and 32 subjects of healthy condition were enrolled in a normal group. In the depression group, the taVNS was applied to bilateral Xin (CO15) and Shen (CO10), at disperse-dense wave, 4 Hz/20 Hz in frequency and current intensity ≤20 mA depending on patient's tolerance, 30 min each time, twice daily. The duration of treatment consisted of 8 weeks. The patients of two groups were undertaken rs-fMRI scanning. The scores of Hamilton depression scale (HAMD), Hamilton anxiety scale (HAMA) and Wisconsin card sorting test (WCST) were observed in the normal group at baseline and the depression group before and after treatment separately. The differential brain regions were observed before and after treatment in the two groups and the value of degree centrality (DC) of fMRI was obtained. Their correlation was analyzed in terms of HAMD, HAMA and WCST scores.
RESULTS:
The scores of HAMD and HAMA in the depression group were all higher than those in the normal group (P<0.05). After treatment, the scores of HAMD and HAMA were lower than those before treatment in the depression group; the scores of total responses, response errors and perseverative errors of WCST were all lower than those before treatment (P<0.05). The brain regions with significant differences included the left inferior temporal gyrus, the left cerebellar peduncles region 1, the left insula, the right putamen, the bilateral supplementary motor area and the right middle frontal gyrus. After treatment, the value of DC in left supplementary motor area was negatively correlated to HAMD and HAMA scores respectively (r=-0.324, P=0.012; r=-0.310, P=0.015); the value of DC in left cerebellar peduncles region 1 was negatively correlated to the total responses of WCST (r=-0.322, P=0.013), and the left insula was positively correlated to the total responses of WCST (r=0.271, P=0.036).
CONCLUSION
The taVNS can modulate the intensity of the functional activities of some brain regions so as to relieve depressive symptoms and improve cognitive function.

8.Pelvic autonomic nerve preservation in rectal cancer: anatomical concept and clinical significance.
Chinese Journal of Gastrointestinal Surgery 2023;26(1):68-74
Colorectal cancer is one of the most common cancers in the world, and surgery is the mainstage treatment. Urogenital and sexual dysfunction after radical resection of rectal cancer has become an important problem for patients, which seriously affects the quality of life. Some patients give up radical surgery for rectal cancer because of the concerns about sexual and urinary dysfunction. The cause of this problem is intraoperative of injury pelvic autonomic nerve. The preservation of the hypogastric nerve during the surgery is important for the male ejaculation. Pelvic splanchnic nerves are mainly responsible for the male erection. The anatomical origin, distribution, and urogenital function of these two nerves are detailed described in this article. At the same time, this article introduces the classification, key points of the operation and the evaluation of autonomic nerve preservation surgery. With the rapid development of minimally invasive surgery, performing radical surgery for rectal cancer is important, we also need to fully understand the anatomical concept of pelvic autonomic nerves, and apply modern minimally invasive surgical techniques to preserve the patient's pelvic autonomic nerves as well. It is an compulsory course and an important manifestation for the standardization of rectal cancer surgery.

OBJECTIVE:
To report on a rare case of Neurofibromatosis type 2 (NF2) manifesting as oculomotor nerve palsy and explore its genetic basis.
METHODS:
A patient with NF2 who had presented at Beijing Ditan Hospital Affiliated to Capital Medical University on July 10, 2021 was selected as the study subject. Cranial and spinal cord magnetic resonance imaging (MRI) was carried out on the patient and his parents. Peripheral blood samples were collected and subjected to whole exome sequencing. Candidate variant was verified by Sanger sequencing.
RESULTS:
MRI revealed bilateral vestibular Schwannomas, bilateral cavernous sinus meningiomas, popliteal neurogenic tumors, and multiple subcutaneous nodules in the patient. DNA sequencing revealed that he has harbored a de novo nonsense variant of the NF2 gene, namely c.757A>T, which has replaced a codon (AAG) encoding lysine (K) at position 253 with a stop codon (TAG). This has resulted in removal of the Merlin protein encoded by the NF2 gene from position 253 onwards. The variant was not found in public databases. Bioinformatic analysis suggested that the corresponding amino acid is highly conserved. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PVS1+PS2+PM2_Supporting+PP3+PP4).
CONCLUSION
The heterozygous nonsense variant c.757A>T (p.K253*) of the NF2 gene probably underlay the disease in this patient with an early onset, atypical but severe phenotype.
