Peripheral nerve injury (PNI) encompasses damage to nerves located outside the central nervous system, adversely affecting both motor and sensory functions. Although peripheral nerves possess an intrinsic capacity for self-repair, severe injuries frequently result in significant tissue loss and erroneous axonal junctions, thereby impeding complete recovery and potentially causing neuropathic pain. Various therapeutic strategies, including surgical interventions, biomaterials, and pharmacological agents, have been developed to enhance nerve repair processes. While preclinical studies in animal models have demonstrated the efficacy of certain pharmacological agents in promoting nerve regeneration and mitigating inflammation, only a limited number of these agents have been translated into clinical practice to expedite nerve regeneration. Chinese herb medicine (CHM) possesses a longstanding history in the treatment of various ailments and demonstrates potential efficacy in addressing PNI through its distinctive, cost-effective, and multifaceted methodologies. This review critically examines the advancements in the application of CHM for PNI treatment and nerve regeneration. In particular, we have summarized the most commonly employed and rigorously investigated CHM prescriptions, individual herbs, and natural products, elucidating their respective functions and underlying mechanisms in the context of PNI treatment. Furthermore, we have deliberated on the prospective development of CHM in both clinical practice and fundamental research.

Objective:To investigate the clinical characteristics and genetic etiology of Duchenne muscular dystrophy (DMD) with myogenic tumors.Methods:The clinical data of 2 children with DMD combined with myogenic tumors diagnosed in Children′s Hospital Affiliated to Zhengzhou University in July 2021 and February 2022 were collected. The relevant literature was reviewed to summarize the clinical characteristics and explore the mechanism of the dystrophin ( DMD) gene in myogenic tumors. Results:A 6-year and 10-month-old boy with DMD (deletion of exon 45) and a 12-year-old boy with DMD (deletion of exon 51) were diagnosed with tumors. They were diagnosed with DMD for delayed motor development in the Department of Neurology of Children′s Hospital Affiliated to Zhengzhou University. They presented with painless masses in the waist. Postoperative pathological diagnosis: the pathology and immunohistochemistry of case 1 showed an alveolar rhabdomyosarcoma (ARMS) and both myogenin and myogenic differentiation 1 positive; the pathology and immunohistochemistry of case 2 showed an alveolar soft part sarcoma(ASPS) and transcription factor enhancer 3 positive; both cases were myogenic tumors. Literature review (including this paper) showed that there were in total 14 cases with DMD combined with myogenic tumors including 13 cases of rhabdomyosarcoma (RMS) and 1 case of ASPS. All of them are male, and the age of onset of the tumors was 4-17 years. Pathological subtypes were described in 6 cases of ARMS and 5 cases of embryonal RMS, and were not described in 2 cases. The 9 cases described all had large deletions in the DMD gene which can change the reading frame of the DMD gene, and all gene mutations did not exceed exon 62. Conclusions:DMD gene with deletion may increase the risk of having myogenic tumors, and RMS is more common, which is manifested as painless mass in early stage. All DMD gene deletions do not exceed exon 62 and lead to change of the gene reading frame with severe clinical phenotype and degenerative changes in muscle function.

Objective To investigate the structural characteristics of intestinal flora in children with sepsis and its association with inflammatory response.Methods A prospective cohort study was conducted.The children with sepsis who were admitted from December 2021 to January 2023 were enrolled as the sepsis group,and the children with non-sepsis who were admitted during the same period were enrolled as the non-sepsis group.The two groups were compared in terms of the distribution characteristics of intestinal flora,peripheral white blood cell count(WBC),C reactive protein(CRP),and cytokines,and the correlation of the relative abundance of fecal flora with WBC,CRP,and cytokines was analyzed.Results At the genus level,compared with the non-sepsis group,the sepsis group had significantly lower relative abundance of Akkermansia,Ruminococcus,and Alistipes and significantly higher relative abundance of Enterococcus,Streptococcus,and Staphylococcus(P<0.05).At the phylum level,Proteobacteria was the dominant phylum(37.46%)in the group of children with a score of≤70 from the Pediatric Critical Illness Score(PICS),and Firmicutes was the dominant phylum in the group of children with a score of 71-80 or 81-90 from the PICS(72.20%and 43.88%,respectively).At the genus level,among the 18 specimens,5 had a relative abundance of>50%for a single flora.Compared with the non-sepsis group,the sepsis group had significant higher levels of WBC,CRP,interleukin-6(IL-6),interleukin-10(IL-10),and tumor necrosis factor-α(P<0.05).The Spearman's rank correlation analysis showed that at the genus level,the relative abundance of Ruminococcus,Alistipes,and Parasutterella in the sepsis group was negatively correlated with the levels of WBC,CRP,and IL-6(P<0.05);the relative abundance of Enterococcus was positively correlated with the CRP level(P<0.01);the relative abundance of Streptococcus and Staphylococcus was positively correlated with the levels of CRP and IL-6(P<0.05);the relative abundance of Streptococcus was positively correlated with WBC(P<0.05).Conclusions Intestinal flora disturbance is observed in children with sepsis,and its characteristics vary with the severity of the disease.The structural changes of intestinal flora are correlated with inflammatory response in children with sepsis.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

This study utilized ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) to rapidly analyze and identify the chemical constituents in five processed products of Strychni Semen(raw, sand-roasted, fried, urine-soaked, and vinegar-processed products). Using PeakView software to extract compound information, 50 chemical components were identified based on retention time, accurate molecular ion peaks, secondary mass spectrometry data, and comparison with reference standards and relevant literature. Specifically, 41 components were identified in raw Strychni Semen, 48 in sand-roasted, 43 in fried, 41 in urine-soaked, and 40 in vinegar-processed products. Principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were employed to identify differential components among the processed products, with variable importance in projection(VIP) values>1 and a t-test with P<0.05 as criteria. PCA revealed significant differences among the five processed products, demonstrating good clustering and separation. OPLS-DA identified 13 differential components, including brucine, strychnine, loganic acid, and chlorogenic acid. The results indicated that S. nux-vomica primarily contained alkaloids, organic acids, and glycosides, with significant compositional differences among the various processed products. Notably, the content of key components such as brucine and strychnine decreased after processing, with the most significant reduction observed in vinegar-processed Strychni Semen. In conclusion, this study provides a comprehensive comparison of the effects of different processing methods on the chemical composition of Strychni Semen, exploring the differences in the material basis of the processed products and offering data to support the scientific rationale behind the processing of Strychni Semen.

Gambogic acid, a caged xanthone compound derived from Garcinia, has been proven to be an important substance basis for the pharmacological effects of the plant. In recent years, it has received continuous attention due to its broad and significant pharmacological activities. Modern pharmacological investigations have demonstrated that gambogic acid endows various therapeutic effects such as anti-inflammatory, antioxidant, and anti-tumor activities, as well as benefits in retinopathy, organ protection, anti-microbial infection, bone protection, and neuropathic pain relief. Nevertheless, there is currently a lack of systematic summary and integration of the pharmacological effects and mechanisms of gambogic acid, which is critical for advancing the clinical application of this natural product. In addition, current research has raised concerns about potential safety risks associated with gambogic acid, such as organ toxicity, developmental toxicity, and hemolysis. Given this, this paper systematically reviewed and summarized the pharmacological effects, mechanisms, and toxicological profiles of gambogic acid, aiming to provide reference and data support for its clinical translation.
