Neuropathic pain, a debilitating condition caused by dysfunction of the somatosensory nervous system, remains difficult to treat due to limited understanding of its molecular mechanisms. Bioinformatics analysis identified cerebellin 2 (CBLN2) as highly enriched in human and murine proprioceptive and nociceptive neurons. We found that CBLN2 expression is persistently upregulated in dorsal root ganglia (DRG) following spinal nerve ligation (SNL) in mice. In addition, transcription factor SOX11 binds to 12 cis-regulatory elements within the Cbln2 promoter to enhance its transcription. SNL also induced SOX11 upregulation, with SOX11 and CBLN2 co-localized in nociceptive neurons. The siRNA-mediated knockdown of Sox11 or Cbln2 attenuated SNL-induced mechanical allodynia and thermal hyperalgesia. High-throughput sequencing of DRG following intrathecal injection of CBLN2 revealed widespread gene expression changes, including upregulation of numerous NF-κB downstream targets. Consistently, CBLN2 activated NF-κB signaling, and inhibition with pyrrolidine dithiocarbamate reduced CBLN2-induced pain hypersensitivity, proinflammatory cytokines and chemokines production, and neuronal hyperexcitability. Together, these findings identified the SOX11/CBLN2/NF-κB axis as a critical mediator of neuropathic pain and a promising target for therapeutic intervention.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

To clarify the species, pathogenicity, and distribution of the pathogens causing the root rot of Atractylodes lancea in Hubei province, the tissue separation method was used to isolate the pathogens from root rot samples in the main planting areas of A. lancea in Hubei. Based on the preliminary identification of the Fusarium genus by the internal transcribed spacer(ITS) sequence, three housekeeping genes, EF1/EF2, Btu-F-FO1/Btu-F-RO1, and FF1/FR1, were amplified and sequenced. Subsequently, a phylogenetic tree was constructed based on these TEF gene sequences to classify the pathogens. The pathogenicity of these strains was determined using the root irrigation method. A total of 194 pathogen strains were isolated using the tissue separation method. Molecular identification using the three housekeeping genes identified the pathogens as F. solani, F. oxysporum, F. commune, F. equiseti, F. tricinctum, F. redolens, F. fujikuroi, F. avenaceum, F. acuminatum, and F. incarnatum. Among them, F. solani and F. oxysporum were the dominant strains, widely distributed in multiple regions, with F. solani accounting for approximately 54% of the total isolated strains and F. oxysporum accounting for approximately 34%. Other strains accounted for a relatively small proportion, totaling approximately 12%. The results of pathogenicity determination showed that there were certain differences in pathogenicity among strains. The analysis of the pathogenicity differentiation of the widely distributed F. solani and F. oxysporum strains revealed that these dominant strains in Hubei were mainly highly pathogenic. This study determined the species, pathogenicity, and distribution of the pathogens causing the root rot of A. lancea in Hubei province. The results provide a scientific basis for further understanding the root rot of A. lancea and its epidemic occurrence and scientifically preventing and controlling this disease.

Objective:To evaluate the effects of glutamine-enriched parenteral nutrition on short-term postoperative outcomes compared with conventional nutritional support in colorectal cancer patients with enteral nutrition intolerance after surgery.Method:A retrospective cohort study was conducted to collect clinical data from colorectal cancer patients who underwent radical resection at the Department of Gastrointestinal Surgery of Zunyi Medical University Affiliated Hospital from January 2019 to December 2021.The differences in postoperative complication rates,perioperative nutritional indicators,and inflammatory factors between the two groups were analyzed.SPSS 29.0 software was used for statistical analysis.Result:Based on whether glutamine was added to parenteral nutrition,178 patients were divided into a control group(conventional nutritional therapy,n=120)and an observation group(glutamine enhanced nutritional therapy,n=58).The incidence of postoperative complications(Clavien Dindo grade≥III)in the control and observation groups was 14.17%(17/120)and 3.45%(2/58),respectively,with a statistically significant difference(P=0.030).The observation group recovered faster than the control group in terms of time to first expectoration,defecation and intake of liquid diet after surgery,and had a shorter hospital stay after surgery(P<0.05).However,there was no significant difference in the 30-day readmission rate between the two groups(P=0.393).There was no statistically significant difference in the changes in total protein,albumin,pre-albumin,neutrophil/lymphocyte ratio and endogenous creatinine clearance rate between the two groups of patients after surgery(P>0.05).There were also significant differences in the changes in lymphocyte count,white blood cell count,neutrophil percentage,alanine aminotransferase,aspartate aminotransferase,total bilirubin,and urea nitrogen levels between the two groups of patients after surgery(P<0.05).Conclusion:Compared with regular nutritional support,postoperative parenteral glutamine supplementation can reduce the incidence of postoperative complications in colorectal cancer patients,promote recovery of bowel function,shorten postoperative hospital stay,improve patient immune function and reduce inflammatory levels.

Objective:To compare the anterior cervical discectomy and fusion (ACDF) and posterior cervical fusion (PCF) in the sagittal plane reconstruction for unstable Hangman fractures.Methods:A retrospective study was conducted to analyze the clinical data of 43 patients who had been surgically treated at Division of Spine Surgery, Department of Orthopedic Surgery, Nanjing Drum Tower Hospital for unstable Hangman fractures from January 2007 to December 2022. There were 32 males and 11 females aged (47.9±14.2) years. They were divided into 2 groups according to their surgical methods: an anterior group of 23 cases who were subjected to ACDF and a posterior group of 20 cases who were subjected to PCE. The 2 groups were compared in terms of operation time, intraoperative bleeding, hospitalization time, and the C 2 subluxation, occipitocervical angle, C 2-C 3 angle, cervical lordosis (CL), and cervical sagittal vertical axis (cSVA) measured on the lateral cervical spine X-rays over the time points of hospital admission, immediate postoperation, and the final follow-up, as well as in terms of the visual analog scale (VAS) for pain and neck disability index (NDI) over the time points of hospital admission and the final follow-up. The American Spinal Injury Association (ASIA) classification was used to assess the neurological status of the patients before surgery and at the final follow-up, and complications were documented. Results:The differences in preoperative general data between the 2 groups were not statistically significant, indicating comparability ( P>0.05). The operation time [(90.3±13.6) min] and hospitalization time [(13.1±2.4) d] in the anterior group were significantly shorter than those in the posterior group [(153.9±26.1) min and (18.5±1.9) d], and the intraoperative bleeding volume in the anterior group [(57.2±15.9) mL] was significantly less than that in the posterior group [(123.2±22.5) mL] ( P<0.05). Compared with the preoperative period in both groups, the C 2 subluxation and C 2-C 3 angle were significantly corrected at immediate postoperation, and well maintained at the final follow-up. The C 2-C 3 angle was significantly better corrected in the anterior group than in the posterior group at immediate postoperation and the final follow-up. The VAS scores and NDI at the final follow-up in both groups were significantly lower than those at admission ( P<0.05), while the differences between the 2 groups were not statistically significant ( P>0.05). Four cases in the anterior group and 2 cases in the posterior group all had their preoperative ASIA grade D improved to grade E at the final follow-up. Three patients in the anterior group developed postoperative hoarseness, which returned to normal at the 3-month follow-up. There was no hoarseness or dysphagia at the final follow-up. Both groups achieved fine fusion at the final follow-up, showing no complications like loosening or fracture of internal fixation. Conclusion:In the sagittal plane reconstruction for unstable Hangman fractures, both ACDF and PCF can lead to satisfactory clinical and radiological outcomes, but the former shows a significant advantage in reconstruction of C 2-C 3 lordosis.

Objective:To explore the clinical efficacy of layered thinning superficial circumflex iliac artery perforator (SCIP) flap based on color Doppler ultrasound (CDU) positioning.Methods:The study was a retrospective observational study. From February 2023 to February 2024, 14 patients who met the inclusion criteria were admitted to the Department of Hand Surgery of Beijing Jishuitan Hospital Affiliated to Capital Medical University, including 11 males and 3 females, aged 15 to 60 years. The wound area was from 7 cm×4 cm to 14 cm×11 cm. Before the flap transplantation surgery, CDU was used to accurately locate the deep fascial exit point of the superficial branch of the superficial circumflex iliac artery. During the surgery, the SCIP flap was thinned in layers to repair the hand and forearm wounds of 11 patients and foot wounds of 3 patients. The flap incision area ranged from 8 cm×5 cm to 15 cm×12 cm. The donor area wounds of flaps were sutured directly. During the surgery, the deep fascial exit point of the superficial branch of the superficial circumflex iliac artery in the flap donor area was observed and compared with the result of CDU positioning before the surgery, and the flap thickness was measured. The flap survival and occurrence of adverse reactions were observed after the surgery. During follow-up, the appearance and texture of flaps, and the wound healing in the donor area was observed. At the last follow-up, the function of the wrist and hand in the affected limbs was evaluated according to the trial standards for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association, and the function of the foot and ankle in the affected limbs was evaluated according to the scoring standard of American Orthopaedic Foot and Ankle Society.Results:During the surgery, the deep fascial exit point of the superficial branch of the superficial circumflex iliac artery in the flap donor area was consistent with the result of CDU positioning before the surgery, and the distance between them was less than 10 mm. The flap thickness was 5 to 8 mm with an average of 6.2 mm. All the flaps survived after surgery. During the follow-up of 5 to 12 months, the flaps had good appearance and texture, all the wounds in the donor areas healed with only linear scar left. At the last follow-up, the function of the wrist and hand in the affected limbs was evaluated as excellent in 9 cases, good in one case, and fair in one case; the function of the foot and ankle in the affected limbs was evaluated as excellent in one case and good in two cases.Conclusions:CDU examination can provide precise preoperative perforator positioning for layered thinning of SCIP flap and contribute to the optimization of flap design, so as to avoid the problem of flap necrosis caused by improper preoperative design to some extent and improve the safety of surgery. In addition, the layered thinning SCIP flap results in less damage to the donor area and is beneficial for the recovery of the affected limb function, which is worthy of clinical promotion.

Objective To understand the changing composition and antibiotic resistance of bacterial species in the clinical isolates from outpatient and emergency department(hereinafter referred to as outpatients)and inpatient children over time in various hospitals,and to provide laboratory evidence for rational antibiotic use.Methods The data on clinically isolated pathogenic bacteria and antimicrobial susceptibility of isolates from outpatients and inpatient children in the CHINET program from 2015 to 2021 were collected and analyzed.Results A total of 278 471 isolates were isolated from pediatric patients in the CHINET program from 2015 to 2021.About 17.1％of the strains were isolated from outpatients,primarily group A β-hemolytic Streptococcus,Escherichia coli,and Staphylococcus aureus.Most of the strains(82.9％)were isolated from inpatients,mainly SS.aureus,E.coli,and H.influenzae.The prevalence of methicillin-resistant S.aureus(MRSA)in outpatients(24.5％)was lower than that in inpatient children(31.5％).The MRSA isolates from outpatients showed lower resistance rates to the antibiotics tested than the strains isolated from inpatient children.The prevalence of vancomycin-resistant Enterococcus faecalis or E.faecium and penicillin-resistant S.pneumoniae was low in either outpatients or inpatient children.S.pneumoniae,β-hemolytic Streptococcus and S.viridans showed high resistance rates to erythromycin.The prevalence of erythromycin-resistant group A β-hemolytic Streptococcus was higher in outpatients than that in inpatient children.The prevalence of β-lactamase-producing H.influenzae showed an overall upward trend in children,but lower in outpatients(45.1％)than in inpatient children(59.4％).The prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKpn),carbapenem-resistant Pseudomonas aeruginosa(CRPae)and carbapenem-resistant Acinetobacter baumannii(CRAba)was 14％,11.7％,47.8％in outpatients,but 24.2％,20.6％,and 52.8％in inpatient children,respectively.The prevalence of multidrug-resistant E.coli,K.pneumoniae,Proteus mirabilis,P.aeruginosa and A.baumannii strains was lower in outpatients than in inpatient children.The prevalence of fluoroquinolone-resistant E.coli,ESBLs-producing K.pneumoniae,ESBLs-producing P.mirabilis,carbapenem-resistant E.coli(CREco),CRKpn,and CRPae was lower in children in outpatients than in inpatient children,but the prevalence of CRAba in 2021 was higher than in inpatient children.Conclusions The distribution of clinical isolates from children is different between outpatients and inpatients.The prevalence of MRSA,ESBL,and CRO was higher in inpatient children than in outpatients.Antibiotics should be used rationally in clinical practice based on etiological diagnosis and antimicrobial susceptibility test results.Ongoing antimicrobial resistance surveillance and prevention and control of hospital infections are crucial to curbing bacterial resistance.
