Lumbosacral radiculopathy refers to the pain syndrome caused by inflammation or mechanical compression of the lumbar nerve root, mainly manifested as low back pain, and radiating to the lower limbs in cutaneous mode, which can be accompanied by numbness, paresthesia, tingling, muscle weakness and loss of specific reflexes and other symptoms, which not only bring physical pain and life inconvenience to the patients, but also bring huge economic burden to the social medical care. Selective nerve root block(SNRB), as a safe, effective, low-cost, precise and minimally invasive clinical technique, can accurately intervene in specific nerve roots and quickly relieve pain symptoms by reducing inflammation and improving the surrounding environment of nerves. However, there are still many challenges and controversies in practice, such as precise targeting requirements, drug selection, potential risks and complications, and differences in efficacy among different patient populations. The purpose of this review is to systematically review and analyze the existing research results on SNRB, so as to provide useful reference and guidance for the further development of this field.

Objective To investigate the effects of meropenem and amikacin on gut microbiota diversity and composition in a neonatal rat model of necrotizing enterocolitis(NEC).Methods Neonatal SD rats(1~2 d,weighing 5~10 g,both sexes)were subjected to establish a NEC model through artificial formula feeding,hypoxic-cold stress,and lipopolysaccharide(LPS)gavage.The rats were randomly divided into normal control group(Group C,n=12),NEC group(Group N,n=20),meropenem intervention group(Group M,n=20),and amikacin intervention group(Group A,n=20).Following modeling,Group M and Group A received intraperitoneal injections of meropenem(125 mg/kg)or amikacin(468 mg/kg),twice daily for 3 consecutive days.Groups C and N were administered an equal volume of normal saline.At the end of the intervention,colonic contents or fecal samples were collected.The gut microbiota structure was analyzed using 16S rDNA high-throughput sequencing.Bioinformatics analysis was performed using the QIIME2 platform.Alpha diversity was evaluated using Chao1,Shannon,and Simpson indices.Beta diversity was assessed based on Bray-Curtis distance through principal coordinate analysis(PCoA)and non-metric multidimensional scaling(NMDS).Venn and UpSet plots were generated to visualize the composition and overlap of operational taxonomic units(OTUs).Linear discriminant analysis effect size(LEfSe)was applied to identify differentially abundant taxa across groups.Results High-throughput 16S rDNA sequencing showed that the N group had significantly lower 3 indices of α diversity than the C group(P<0.01),that is,a Chao1 index from 230 to 40,a Shannon index from 1.65 to 0.85,and a Simpson index from 0.65 to 0.42.After antibiotic intervention,both the M group and A group obtained obvious increases in the Chao1 index than the N group(P<0.001),with a greater increase observed in the M group than in the A group(P<0.05).However,neither antibiotic group exhibited notable improvements in the Shannon index or Simpson index compared with the N group(P>0.05).Venn and UpSet analyses revealed that the M group had the highest number of unique OTUs(283),while the A group shared the most OTUs(63)with the C group.PCoA and NMDS analyses indicated that the microbial structure of the A group was closer to that of the C group,with better clustering.Taxonomic composition and LEfSe analysis demonstrated that the N group was enriched with potentially pathogenic taxa such as Escherichia coli B2 and Klebsiella under the phylum Proteobacteria,while beneficial bacteria including Lactobacillaceae and Bifidobacteriaceae(phylum Firmicutes)were significantly reduced,indicating severe dysbiosis.In contrast,the A group exhibited a significant increase in beneficial bacteria and a structural tendency toward ecological recovery.The M group,however,was enriched with various conditionally pathogenic and environmentally associated genera,displaying a microbial configuration notably deviating from a healthy state.Conclusion Meropenem and amikacin exhibit differential regulatory effects on the intestinal microbiota in the context of NEC.Amikacin demonstrates superior efficacy in restoring microbial stability and levels of beneficial bacteria,whereas meropenem,although effective for early infection control,warrants caution due to its potential long-term impact on the gut microbiome.

Objective:This study aimed to analyze the genomic characteristics of Varicella-Zoster Virus (VZV) strains circulating in Jilin province from 2010 to 2023.Methods:Vesicle fluid from 78 sporadic cases with VZV infection were collected in Jilin province from 2010 to 2023, after detecting by Real-time PCR, 26 specimens (CT<25) were detected by PCR. Open reading frame 22(ORF22), ORF38 and ORF62 were amplified and analyzed. Genotyping was confirmed by SNPs ORF22 (37902, 38019, 38055, 38081 and 38177) and ORF38 (69424). Vaccine strains were indentified from wild-type strains according to ORF38 (69349) and ORF62 (106262, 107252, and 108111). Sequences were analyzed by homologous comparison and phylogenetic analysis.Results:The comparison with Dumas sequence revealed that SNPs (37902, 38055, 38081 and 38177) in ORF22 and ORF38 (69424) have mutations similar to the pOka strain, which belong to clade 2. Compared to the Dumas and Baike strains, all 26 samples were wild-type strains. JL2016-4 strain changes from threonine to asparaginyl at position 38059, JL2021-4 strain changes from arginine to proline at position 37933, from aspartic acid to tyrosine at position 37935, and from aspartic acid at base 38031 to tyrosine. JL2023-1 strain changes from arginine to leucine at position 37933.Conclusions:VZV has been prevalent for 14 years in Jilin province. The main epidemic strains belong to the clade 2. We should strengthen the monitoring of VZV outbreaks and raise the coverage rate of VZV vaccination.

Objective:To compare the efficacy of maxillary distraction osteogenesis (DO) and Le FortⅠ osteotomy (LFⅠ) in patients with complex cleft lip and palate.Methods:A retrospective study was conducted, clinical data were collected involving patients with complex cleft lip and palate who required combined orthodontic and orthognathic treatment and were treated at the Stomatological Hospital of Chongqing Medical University from January 2015 to December 2022. Patients were divided into three groups based on the surgical method used for the maxilla: total maxillary distraction (TMD, group A), anterior maxillary distraction (AMD, group B), and Le Fort Ⅰ osteotomy (LFⅠ, group C). Cone-beam CT scans and lateral cephalograms were obtained preoperatively and at 3 months postoperatively. Three-dimensional reconstructions were performed using Mimics 21.0 and Dolphin Imaging 11.9 software to evaluate changes in craniofacial morphology and airway. Data analysis was conducted using SPSS 25.0. Intragroup comparisons before and after surgery were performed using the Wilcoxon rank sum test, and intergroup comparisons among the three groups were conducted using the Kruskal-Wallis H test. Results:A total of 15 patients were included, with 5 patients in each group. The cohort comprised 8 males and 7 females, aged between 15 and 21 years. There were no statistically significant differences in the distribution of gender, age, or cleft lip and palate classification among the three groups ( P>0.05). Postoperatively, all three groups showed improvement in maxillary hypoplasia. Compared to preoperative measurements, the angle formed by the points A (subspinale), N (nasion), and B (supramentale) (ANB angle) increased in all three groups (all P<0.05). The vertical distance from point A to the nasion perpendicular (A-Nperp) increased in groups A and B ( P<0.05 for both) but not in group C ( P>0.05). The area of the alveolar gap showed an increasing trend in all three groups ( P>0.05). The mandibular plane angle (FMA) decreased postoperatively in group B but showed an increasing trend in the other two groups, though the differences were not statistically significant ( P>0.05). Postoperative airway volume increased or showed an increasing trend in groups A ( P<0.05) and B ( P>0.05) but decreased in group C ( P>0.05). Intergroup comparisons showed significant differences in the angle formed by the sella (S), nasion (N), and point A (SNA angle) and the vertical distance from the anterior nasal spine to the coronal plane (ANS-CP) ( P<0.05). Group A had significantly larger SNA angles and ANS-CP values than group B, and the ANS-CP value in group A was significantly larger than in group C (all P<0.05). There were no other statistically significant differences among the groups ( P>0.05). Conclusion:For patients with severe maxillary hypoplasia due to complex cleft lip and palate, TMD can correct sagittal discrepancies between the upper and lower jaws, increase upper airway volume, but may potentially enlarge the alveolar gap area and increase vertical height of the maxilla. AMD result in less change in maxillary position compared to TMD and is mainly used for patients with severe maxillary dental crowding, needing increased arch length, having minor sagittal discrepancies, or with preexisting velopharyngeal dysfunction. LFⅠ result in changes in maxillary position similar to AMD but less than TMD, making it suitable for patients with moderate maxillary hypoplasia and mild maxillary dental crowding. The advantage of LFⅠ lies in its precise postoperative occlusal design and accurate three-dimensional movement of the jaw.
