The rapid emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants that evade immunity elicited by vaccination has posed a global challenge to the control of the coronavirus disease 2019 (COVID-19) pandemic. Therefore, developing countermeasures that broadly protect against SARS-CoV-2 and related sarbecoviruses is essential. Herein, we have developed a lipid nanoparticle (LNP)-encapsulated mRNA (mRNA-LNP) encoding the full-length Spike (S) glycoprotein of SARS-CoV-2 (termed RG001), which confers complete protection in a non-human primate model. Intramuscular immunization of two doses of RG001 in Rhesus monkey elicited robust neutralizing antibodies and cellular response against SARS-CoV-2 variants, resulting in significantly protected SARS-CoV-2-infected animals from acute lung lesions and complete inhibition of viral replication in all animals immunized with low or high doses of RG001. More importantly, the third dose of RG001 vaccination elicited effective neutralizing antibodies against current epidemic XBB and JN.1 strains and similar cellular response against SARS-CoV-2 Omicron variants (BA.1, XBB.1.16, and JN.1) were observed in immunized mice. All these results together strongly support the great potential of RG001 in preventing the infection of SARS-CoV-2 variants of concern (VOCs).

Intraluminal thrombus(ILT)at the vertebral artery origin is rare and often missed due to atypical symptoms.However,it poses a high risk of artery-to-artery embolism and severe posterior circulation ischemia.This article reports a case of missed diagnosis of ILT to improve the diagnostic ability.The patient,a 49-year-old male was admitted to emergency department with sudden dizziness accompanied by nausea for 12 hours.Head CT suggested posterior circulation ischemia.Patient was given aspirin 0.2 g/d and atorvastatin 20 mg/d orally and discharged from the hospital.Head MRI in the outpatient department showed a recent infarct in the right cerebellar hemisphere next day.On the 28th,dizziness recurred,accompanied by unsteady walking and right-sided hemisensory numbness.The symptoms persisted and did not improve.He was admitted to the hospital on the 29th.Cervical CTA showed severe stenosis at the origin of the right vertebral artery,filling defect in the distal lumen combined with the Donut sign.Thus,ILT was diagnosed.The drug treatment regimen was adjusted to aspirin 100 mg/d combined with clopidogrel 75 mg/d for a total of 15 weeks.High-resolution MRI of the cervical blood vessels in the outpatient department showed occlusion of the V1-V2 segment of the right vertebral artery.On November 2,endovascular treatment was performed under local anesthesia.At 90 days and 6 months of follow-up after the operation,no recurrence of cerebral ischemia events occurred,and the mRS score was 0.This case highlights the need for vigilance toward ILT in posterior circulation ischemia when initial imaging is inconclusive.Early dynamic CTA(5-7 days)combined with dual antiplatelets may prevent thrombus progression and improve outcomes.

Objective:To compare the effect of transcranial magnetic stimulation (rTMS) of the contralesional hemisphere at different frequencies on the recovery of upper limb motor function after a moderate-to-severe ischemic stroke.Methods:The inter-hemisphere compensation model was applied along with electroencephalogram (EEG) power spectrum density measurements. Thirty stroke survivors were randomly assigned to a sham stimulation group ( n=9), a high-frequency stimulation group ( n=11) or a low-frequency stimulation group ( n=10). In addition to physical and pharmacological therapy, the low-frequency and high-frequency groups received 1Hz or 5Hz rTMS, while the sham group received sham stimulation. The rTMS was delivered over the contralesional (unaffected) hemisphere once daily for 20 minutes over 15 consecutive days. Before, as well as 7 and 15 days after the treatment, all of the subjects′ motor functioning was assessed using the Fugl-Meyer Assessment for the upper extremity (FMA-UE) and their ability in the activities of daily living was assessed using the modified Barthel Index (MBI). Resting-state EEGs with the eyes closed were also recorded, and absolute alpha power across the whole brain was calculated. Changes from baseline FMA-UE and MBI scores and absolute alpha power were analyzed using one-way and repeated-measures analysis of variance. Results:After the treatment, significant within-group improvements from baseline were observed in the FMA-UE scores, MBIs and absolute alpha power, except for absolute alpha power in the low-frequency and sham groups. The repeated-measures analysis of variance revealed significant time × group interactions for FMA-UE ( F=9.926, P≤0.001), MBI ( F=8.789, P≤0.001) and absolute alpha power ( F=4.511, P≤0.05). So the treatment effects varied among the groups. Post hoc Bonferroni-corrected comparisons showed that the high-frequency group exhibited significantly greater improvements from baseline in terms of all three indicators compared with the other two groups. Conclusions:High-frequency (5Hz) rTMS applied to the contralesional hemisphere produced greater improvement than low-frequency (1Hz) stimulation in the upper limb motor function of patients with moderate-to-severe stroke. These findings support the use of the interhemispheric compensation model to guide rTMS therapy, particularly for patients with FMA-UE scores below 43.

Objective To explore the efficacy of bilateral facial muscle training combined with visual electromyography biofeedback on facial nerve function recovery in patients with idiopathic facial nerve palsy. Methods Patients with idiopathic facial nerve palsy admitted to Shanghai Fifth People’s Hospital, Fudan University from July 2022 to July 2024 were selected and randomly divided into a control group and an intervention group. The control group received conventional physical factor therapy, while the intervention group received bilateral facial muscle training combined with visual electromyography biofeedback therapy based on the control group’s regimen. After 20 treatment sessions, the total effective rate, the House-Brackmann (H-B) facial nerve grading system, the Sunnybrook Facial Grading System (SFGS) score, and the average value ratio of maximal amplitudes of bilateral frontalis and zygomaticus muscles were compared between the two groups. Results A total of 90 patients were included, 45 in each group. After 20 treatment sessions, the total effective rate was significantly higher in the intervention group than in the control group (84.4% vs 75.6%, P＝0.003). Compared with the control group, the intervention group demonstrated a significantly lower H-B grade (P＝0.003) and a higher SFGS score (P＝0.001). The average value ratios of maximal amplitudes of the affected versus healthy side frontalis (P＝0.013) and zygomatic (P＝0.022) muscles were higher in the intervention group than in the control group. Conclusions Bilateral facial muscle training combined with visual electromyography biofeedback is an effective approach for treating idiopathic facial nerve palsy, effectively promoting the recovery of facial nerve function, and improving facial symmetry and facial muscle function.

Amorphous calcium phosphate（ACP）is a component of urinary stones，primarily forming mixed stones with calcium oxalate，while pure ACP stones are relatively rare. This article reports a case of a patient with an ACP bladder stone who was admitted due to progressive dysuria over 5 years，which had worsened in the past months. Upon admission，tPSA was 29.63 ng/ml. CT and enhanced MRI revealed multiple bladder stones and prostatic hyperplasia. The patient underwent ultrasound-guided prostate biopsy and transurethral cystolithotripsy with pneumatic lithotripsy. Postoperative infrared spectroscopy confirmed the stone composition as ACP，and prostatic adenocarcinoma was diagnosed by prostate biopsy pathology. Endocrine therapy was administered postoperatively，and follow-up imaging at 3 months showed no stone. This article presents the first reported case of an ACP bladder stone coexisting with prostate cancer，providing important clinical insights into the etiology of such stones and the rare local manifestations of prostate cancer.

Objective To investigate the protective effect of apigenin on renal tubular epithelial cells(HK-2)induced by hyperglycemia and its potential mechanism.Methods HK-2 cells were incubated with d-glucose to establish an in vitro diabetic nephropathy model.Cell viability,apoptosis and oxidative stress were assessed.The mRNA levels of nuclear factor erythroid-2 related factor 2(Nrf2),heme oxygenase-1(HO-1)and epoxy chloropropane Kelch sample related protein-1(Keap1)were measured by quantitative real-time-PCR(q-PCR).Western blot analysis was performed to measure the protein expression of Nrf2.Results In HK-2 cells,high glucose decreased cell viability in a concentration-and time-dependent manner.Apigenin improved the viability of HK-2 cells under high glucose stress,reduced apoptosis and proinflammatory cytokine production,and inhibited the oxidative stress.Apigenin increased mRNA expression of Nrf2 and HO-1,increased expression of Nrf2 protein and reduced the mRNA level of Keap1.Inhibition of Nrf2 using small interfering RNA(siRNA)abolished the protective effects of apigenin on HK-2 cells under high glucose stress.Conclusion Apigenin treatment can alleviate the damage of HK-2 cells under high glucose stress,and exert the anti-oxidation and anti-inflammation effects through Keap1-Nrf2-ARE pathway.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
