RESUMEN
Objective To observe the changes in visual function and retinal structure in patients with non-arteritic anterior ischemic optic neuropathy(NAION)at different stages and analyze the correlation between visual function and structural indicators.Methods A retrospective study was conducted on 33 patients(33 eyes)with NAION presented within 3 weeks of onset.Changes in visual function[best corrected visual acuity(BCVA),visual field mean deviation(MD),pattern standard deviation(PSD),and visual field index(VFI)]and retinal structure[peripapillary retinal nerve fi-ber layer(pRNFL)]thickness,macular ganglion cell complex(mGCC)thickness and loss volume,and radial peripapillary capillary(RPC)density)were analyzed from 4 to 12 weeks of onset and over 12 weeks of onset.The change features of and correlation between visual function indicators and structural indicators were analyzed.Results The BCVA of NAION eyes exhibited significant improvement with disease progression(P=0.021),with a statistically significant difference be-tween onset＞12 weeks and onset≤3 weeks(P=0.020)and no statistically significant difference between onset≤3 weeks and onset from 4 to 12 weeks or between onset from 4 to 12 weeks and onset＞12 weeks(P=0.158 and 0.100).There were no significant differences in MD,PSD and VFI across different stages of NAION(P=0.419,0.767 and 0.134).The pRNFL thickness(average,superior,and inferior),RPC density(average,superior,and inferior),and mGCC thick-ness(average,superior,and inferior)significantly decreased with disease progression(all P＜0.001),while focal loss volume(FLV)and global loss volume(GLV)of mGCC significantly increased with disease progression(both P＜0.001).The differences in these indicators above among each stage were statistically significant(all P＜0.05).Correlation analysis revealed that the BCVA demonstrated positive correlations with mGCC thickness(average and inferior)and RPC density(average and inferior)(all P＜0.05).Conversely,it exhibited negative correlations with FLV and GLV(both P＜0.05).There were no correlations between BCVA and pRNFL thickness(average,superior,and inferior),superior mGCC thick-ness,and superior RPC density(all P＞0.05).MD and VFI showed positive correlations with mGCC thickness(average and inferior)and RPC density(average,superior,and inferior)(all P≤0.001)and negative correlations with GLV(both P＜0.001),but no correlations with pRNFL thickness(average,superior,and inferior),superior mGCC thickness,and FLV(all P＞0.05).PSD showed no correlations with pRNFL thickness(average,superior,and inferior),mGCC thickness(average,superior,and inferior),FLV,GLV,and RPC density(average,superior,and inferior)(allP＞0.05).Conclu-sion The changes in visual acuity and visual field with the progression of NAION are associated with changes in mGCC thickness and RPC density,but not correlated with changes in pRNFL thickness.This suggests that visual function and reti-nal structural changes do not occur synchronously.

Objective To construct a management scheme of nursing assistants in unaccompanied hospitals and explore its application effect.Methods The management team of nursing assistants in unaccompanied hospitals was set up.On the basis of investigating the current situation of nursing assistants'team management,the management scheme of nursing assistants was constructed by ORTCC management model for references,including 5 parts:determining management objectives,perfecting rules system,building hierarchical training system,checking and assessing,and shaping cultural system.Convenience sampling method was used to select 92 nursing assistants in an unaccompanied hospital in Xiamen,Fujian Province from June 2021 to June 2022 as application subjects.The post competence of nursing assistants and the satisfaction of patients and nurses to nursing assistants were compared before the application of the management scheme(June-December 2021)and after the application(January 2022-June 2022).Results After the application of ORTCC management model,the total score of post competency of medical nursing assistants increased from[65(64,67)]to[91(90,92)];the excellent rate of post competency level increased from 1.09％to 67.39％;the satisfaction of patients with nursing assistants increased from 61.99％to 88.62％;the scores of nurses'satisfaction with nursing assistants in all dimensions were significantly higher than before(all P＜0.05),and the overall evaluation was improved from 92.73％to 99.24％.Conclusion The use of the ORTCC management model for nursing assistants can effectively improve their post competence,improve the satisfaction of patients and nurses,and help to further stabilize and develop the medical nursing assistants staff.
RESUMEN
Objective:To investigate the clinical characteristics and pathogenic gene mutation of lateral meningocele syndrome(LMS).Methods:We retrospectively collected the clinical manifestations, laboratory examination, imaging examinations, and genetic analysis of a neonate with LMS which was diagnosed at the Department of Neonatology of the Second Affiliated Hospital of Wenzhou Medical University in May 2020. Relevant literature up to February 2021, retrieved from PubMed, OMIM, CNKI, Wanfang, and CQVIP database with the terms of "lateral meningocele syndrome", " NOTCH3", were reviewed to summarize the clinical characteristics, pathogenesis, and genetic etiology of this disease. Results:A full-term male newborn was admitted to our hospital due to feeding difficulty 7 d after birth. The clinical characteristics included hypotonia, dysphagia, hypertension, lateral spinal meningocele, craniofacial anomaly, and cryptorchidism. Abnormal spinal MRI and brainstem evoked potential were also observed. Whole exome sequencing revealed a heterozygous frameshift variation c.6667_6686del(p.Ala2223Profs*12) of NOTCH3 gene located in 19p13.12, which was not detected in the parents. Only 12 English literature were retrieved, with 17 patients from 15 pedigrees. Out of the 18 patients including the index case, 10 were genetically diagnosed as LMS. The age at diagnosis ranged from 15 d to 55 years. Regarding the clinical features, multiple lateral thoracolumbar spinal meningoceles (18/18) was the most common one, followed by retrognathia and low-set ears (16/18), eyelid ptosis and down slanting palpebral fissures (15/18), hypotonia (13/18), hypertension (11/18), developmental delay (9/18), mixed or conductive hearing loss (9/18), cardiovascular dysplasia (7/18), and cryptorchidism (7/10). A total of nine NOTCH3 gene variants were detected, all were heterozygous variants, including six frameshift and three nonsense variants. Conclusions:LMS is caused by NOTCH3 gene mutation with the clinical characteristics including multiple lateral thoracolumbar spinal meningoceles, craniofacial dysmorphisms, hypotonia, hypertension, developmental delay, difficulty in feeding, cryptorchidism, etc.

Objective To investigate the possible mechanisms of ox-LDL on vascular smooth muscle cells (VSMC) with and without exogenous zinc finger protein A20 gene. Methods VSMC were trans-fected with plamid containing A20 gene and incubated with ox-LDL. TLR4 and LOX-1 mRNA expression were measured by RT-PCR. Results After VSMC incubated with ox-LDL, the expression of LOX-1 and TLR-4 mRNA reached a higher level. However, when VSMC were transfected with plasmid containing A20 gene, the NF-kB nuclear translocation and the ability of migration reduced to normal level. Conclusions ox-LDL can significantly activate NF-kB signaling system and enhance migration in VSMC. The activation may induce the inflammatory response in arterial wall, the migration of VSMC to the intima, and triggering the process of atherosclerosis. Transfecting plasmid containing A20 gene significantly inhibited the activation of NF-kB and the ability of migration of VSMC. A20 effects might be through inhibiting NF-kB signaling. Meanwhile, A20 blocked the development of atherosclerosis.
