Methods: Motor-evoked potentials (MEPs) and somatosensory-evoked potentials (SEPs) were recorded in 48 patients with TOLF (hybrid 20 vs. en bloc 28) during surgery. Patients were categorized based on MEP/SEP improvement, deterioration, or no change, and MEP/SEP improvement rates were measured in the improvement group. Furthermore, all patients were assessed using the Ashworth and modified Japanese Orthopedic Association scores. Results: The incidences of both MEP/SEP improvement (21.4% vs. 25.0%, p=0.772) and deterioration (21.4% vs. 20.0%, p=0.904) were similar between the en bloc and hybrid laminectomy groups, and no difference in preoperative and postoperative clinical assessments was observed between the two groups (p>0.05). In four patients (4/28, 14.3%) undergoing en bloc laminectomy, MEP amplitudes initially increased after OLF removal but gradually decreased. This delayed MEP reduction did not occur in the hybrid laminectomy group. Furthermore, more patients undergoing en bloc laminectomy had CFL than those undergoing hybrid laminectomy (46.4% vs. 15.0%, p=0.023). In the improvement group, the hybrid laminectomy group exhibited higher MEP improvement rates in the bilateral abductor hallucis than the en bloc laminectomy group (left side: 213.4%±35.9% vs. 152.5%±41.0%, p=0.028; right side: 201.2%±32.0% vs. 145.2%±46.3%, p=0.043). Conclusions Compared with en bloc laminectomy, hybrid laminectomy may be a safe and effective method for treating multilevel TOLF, potentially reducing intraoperative spinal cord irritation and CFL and causing relatively better functional recovery.

Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia （FD）， this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes， postprandial distress syndrome （PDS） and epigastric pain syndrome （EPS）. The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS， whereas local acupoints alone may be more suitable for EPS. Additionally， the study explores the impact of various factors， such as stimulation techniques， needling order， intensity or stimulation parameters， and depth， on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations， local versus distal， affect the treatment outcomes of FD subtypes， providing new insights for clinical acupuncture prescriptions.

Heme oxygenase-1(HO-1)is an inducible heme oxygenase and a catalytic enzyme for heme decomposition reactions,which can catalyze the heme decomposition into CO,biliverdin and Fe2+.HO-1 and its metabolites have anti-inflammatory,antioxidant and anti-apoptotic effects in human body,and play an important role in neurodegenerative diseases such as Alzheimer's disease,Parkinson's disease,amyotrophic lateral sclerosis,and Huntington's disease.This article will review the production,distribution,and gene structure of HO-1,the biological characteristics of its metabolites,and the role and mechanism of HO-1 in neurodegenerative diseases,in order to provide a theoretical basis for the clinical application of HO-1.

Objective To explore the clinical features,diagnostic methods,and treatment strategies for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)encephalitis confirmed through cerebrospinal fluid(CSF)analysis.Methods The clinical data of patients diagnosed with SARS-CoV-2 encephalitis through CSF analysis in the Neurology Intensive Care Unit of the First Affiliated Hospital of Nanchang University from March 2022 to March 2023 were collected.Additionally,the relevant literature published in both domestic and international databases was analyzed and synthesized.Results The main neurological manifestations of five cases included decreased consciousness(5/5),psychiatric disorder(2/5),seizures(2/5),quadriplegia(1/5),and headaches(1/5).Two cases had abnormal brain magnetic resonance imaging(MRI)changes,involving the temporal lobe,insular lobe,thalamus,hippocampus,and pons.Additionally,CSF analysis showed mildly elevated protein levels in two cases.Next-generation sequencing(NGS)of the CSF identified SARS-CoV-2 in all five cases(sequence:41-1620),and human herpesvirus 1 in one case(sequence:21).The treatment regimen for all cases included antiviral therapy,three were additionally treated with glucocorticoids and one received immunoglobulin therapy.All cases achieved a favorable outcome(mRS:0-2).Conclusion SARS-CoV-2 has the potential to induce encephalitis/meningitis due to its neurotropic nature.The consideration of this condition is warranted in patients with relevant epidemiological history and symptoms related to the central nervous system.CSF NGS serves as a valuable tool for early diagnosis,while active antiviral therapy and immunotherapy may improve patient outcomes.

Objectives:To investigate the association between social determinants of health(SDOH)and incident stroke and analyze the main risk factors for stroke among resident with different SDOH levels. Methods:From 2012 to 2015,30 036 residents(≥35 years old)from 30 districts in 14 provincial-level administrative divisions in China were enrolled this study based on stratified multi-stage-random-sampling method.The prevalence of cardiovascular diseases and related risk factors were investigated,and stroke events were followed up in 2018 to 2019.Principal component analysis was performed to establish SDOH scores based on 9 indicators related to socioeconomic and healthcare resources,participants were divided into low SDOH group(n=8 343)when it was≥-2.01 to<-1.14,middle SDOH group(n=7 257)when it was≥-1.14 to<0.10,and high SDOH group(n=8 457)when it was≥0.10 to≤5.79.Multivariate Cox regression was applied to estimate the association of SDOH levels with incident stroke.The random survival forest method was used to analyze the major risk factors in different SDOH levels. Results:A total of 24 057 participants were finally included,669(2.8%)participants developed stroke during a mean of(4.7±0.8)years follow-up.The incidence densities of stroke in the low,medium,and high SDOH groups were 468.39,628.85,and 700.39/100 000 person-years,respectively(Pdifference<0.05,Ptrend=0.01).Compared with individuals with low SDOH level group,fully HR for incident stroke among those with medium and high were 1.91(95%CI:1.54-2.36)and 1.59(95%CI:1.30-1.95),respectively(Ptrend<0.001).Advanced age is the primary risk factor for stroke in the population,especially in districts with high SDOH level.In districts with medium SDOH level,diabetes is an important risk factor for stroke.High blood pressure and alcohol consumption are important modifiable risk factors in low SDOH level districts. Conclusions:Present study shows that higher levels of SDOH are associated with increased risk of stroke.The main risk factors for stroke differ among participants with different SDOH level districts.Targeted interventions should be implemented to improve the prevention and treatment of stroke in populations with different levels of SDOH.

Objective:To explore the relationship between the degree of devascularization and clinical outcomes after interventional embolization and sclerotherapy for peripheral arteriovenous malformations.Method:A retrospective analysis was conducted on the data of 37 patients with peripheral arteriovenous malformations admitted at Department of Cardiovascular Surgery, China-Japan Friendship Hospital from July 2021 to June 2023. All patients received the treatment of "nidus" and/or outflow veins embolization combined with sclerotherapy injection. Two experienced physicians evaluated the degree of devascularization before and after treatment, and conducted a correlation study with clinical outcomes after follow-up.Result:All 37 patients were symptomatic. Swelling and pain accounted for 75.7% of all the cases. Twenty-six patients received only one procedure, 3 patients received re-interventional treatments. The average follow-up time was（13.3±5.0）months. Clinical symptoms were completely relieved in 14 patients, and partial relief in 22 patients. The overall effective rate was 97%. There were 6 patients with degree of de vascularization<50% during procedure, 16 patients with degree of 50%-75%, and 5 patients with degree of 75%-90%, 10 cases with degree over 90%. Patients with devascularization degrees less than 60% can not achieve clinical symptom relief.Conclusions:There is a positive correlation between the degree of devascularization and clinical outcomes in the interventional embolization and sclerotherapy of peripheral arteriovenous malformations, and 60% of the degree of devascularization can serve as the "threshold" for effectiveness of treatment.

Objective:To explore the effectiveness and safety of endoscopic ultrasound-guided pancreatic duct drainage (EUS-PD).Methods:A retrospective analysis was conducted on data of 16 patients who underwent EUS-PD because of endoscopic retrograde pancreatography (ERP) failure, poor effectiveness or anatomical changes and couldn't undergo the routine ERP in Nanjing Drum Tower Hospital from June 2018 to July 2022. The technical success of EUS-PD, clinical efficacy and post-procedure adverse events were analyzed.Results:In the 16 patients, there were 14 males and 2 females, with age of 50.69±12.95 years. A total of 19 times of EUS-PD operations were included, 3 of them were rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP), 15 transgastric or transenteric EUS-guided stent placement and 1 was EUS-guided nasopancreatic duct placement. Technical success was achieved in 84.21% (16/19) patients, and among whom 93.75% (15/16) achieved clinical success. The overall incidence of postoperative adverse events was 52.63% (10/19) including 47.37% (9/19) abdominal pain, 15.79% (3/19) fever and 15.79% (3/19) postoperative pancreatitis. All adverse effects were relieved after general conservative treatment and no primary disease or surgery-related death occurred. The mean follow-up was 17.6 (8.2,22.3) months and 93.75% (15/16) of the patients were followed up. By the time of follow-up, 76.92% (10/13) of the patients who had successfully received EUS-PD had no recurrence of abdominal pain or distension.Conclusion:EUS-PD is a safe and effective alternative therapy for those with pancreatic diseases with ERP failure, poor efficacy or anatomical changes.

Objective:To explore the clinical effects of nerve-carrying peroneal artery perforator flaps in repairing nerve defects in the late stage of wrist electric burns.Methods:This study was a retrospective observational study. From December 2019 to May 2023, five patients with sensory dysfunction in hands due to nerve defects in the late stage of wrist electric burns were treated in the Affiliated Hospital of Zunyi Medical University and met the inclusion criteria. There were 4 males and 1 female, aged 7 to 48 years. Four patients had defects in both median nerve and ulnar nerve, one patient had a defect solely in median nerve, and the length of nerve defects ranged from 5 to 12 cm. Four patients underwent transplantation of peroneal artery perforator flaps carrying sural nerve and superficial peroneal nerve, and 1 patient underwent transplantation of peroneal artery perforator flap only carrying sural nerve. The wounds in flap donor sites were all directly sutured. One patient had tendon adhesion and release of tendon adhesion was performed during the same surgery; 3 patients had combined defects in the wrist flexor muscle group, including 2 patients received autologous tendon grafting during the same surgery, and one patient received reconstruction of finger flexion function with a gracilis myocutaneous flap in the second stage; 1 patient had combined wrist flexion contracture which was surgically released in the second stage. During follow-up after surgery, the survival of the flaps was observed, and the healing time of the incisions or sutures in flap donor and recipient sites and the recovery time of hand sensation were recorded. At the last follow-up, the scar formation and loss of sensation in the foot were observed, and flexor strength and sensory function of the fingers were evaluated based on the evaluation criteria for tendon and nerve repair standards of hands in the trial standards for evaluation of partial function of the upper extremity by the Hand Surgery Society of Chinese Medical Association.Results:All patients were followed up after surgery for 12 to 24 months, and all flaps of patients survived. The healing time for the incisions or sutures in flap donor and recipient sites was about 2 weeks, and the hand sensation recovered in 6 months after surgery. At the last follow-up, linear scar was left in the donor site on the lower leg; patients had partial sensory impairment on the dorsum of the foot, but there was no skin ulceration, which did not affect wearing shoes or walking; finger flexor strength was rated as grade 4 in 1 patient, grade 3 in 3 patients, and grade 2 in 1 patient; the sensory function of hands was evaluated as S3 + level in 4 patients, with the two-point discrimination distance of the skin ranging from 8 to 11 mm, while the sensory function of hands was evaluated as S3 level in 1 patient, with the two-point discrimination distance of the skin of 13 mm. Conclusions:Using the nerve-carrying peroneal artery perforator flaps to repair the nerve defects in the late stage of wrist electric burns, the sensation of hands can be restored in 6 months after surgery, with only linear scar in the flap donor sites and hypoesthesia in some areas of the dorsum of the foot. When combined with the reconstruction of finger flexion function, the overall function of hands can be effectively improved.
