Objective:To develop and validate clinical predictive models for identifying poor short-term response to recombinant human growth hormone(rhGH) treatment in children with short stature.Methods:A retrospective analysis was conducted on 118 children diagnosed with growth hormone deficiency or idiopathic short stature who were treated at the First Affiliated Hospital of Zhengzhou University and two other hospitals between January 1, 2020, and January 1, 2024. A poor response to rhGH was defined as a height increase of less than 0.2 standard deviation score(SDS) after 6 months of rhGH treatment. LASSO regression was used to identify predictive variables from baseline and follow-up data. Two logistic regression models were conducted: Model A(incorporating baseline variables only) and model B(incorporating both baseline and follow-up variables), and nomograms were created for visualization. External data and internal resampling were used for dual validation of the models, and their performance was compared.Results:A total of 118 children with short stature were included. Six baseline predictive variables(diagnosis, initial height SDS, bone age, bone age-chronological age difference, rhGH dose, and gender) and one follow-up variable(height SDS after 3 months of rhGH treatment) were identified. Area under the curve values for Model A and Model B were 0.753(95% CI 0.696-0.811) and 0.930(95% CI 0.891-0.975), respectively. Calibration curves, decision curve analysis, and other evaluation metrics demonstrated good discrimination and clinical utility for both models. Model B, incorporating the 3-month follow-up variable, showed superior predictive performance compared to Model A. Conclusions:The clinical prediction models developed in this study(Model A and Model B) are practical and reliable tools for quantitatively, conveniently, and intuitively identifying children with short stature at risk of poor response to rhGH treatment.

Objective:To investigate the clinical efficacy and safety of ultrasonic bone scalpel in nasal osteotomy.Methods:A retrospective analysis was conducted on clinical data from the patients who received ultrasonic bone scalpel-assisted nasal osteotomy in the Nasal Plastic & Reconstructive Surgery Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2023 and April 2024. All patients underwent open lateral approach osteotomy using an ultrasonic bone scalpel under direct vision, combined with augmentation rhinoplasty using autologous costal cartilage grafting. Intraoperatively, the nasal dorsum was fully exposed, and the lateral nasal cartilage was separated from the nasal septum, followed by precise bone tissue incision using the ultrasonic bone scalpel. Parameters recorded included operative time, and postoperative complications. Based on the standardized photographs taken before the operation and during the 6-month follow-up after the operation, the observer global aesthetic improvement scale (GAIS) was evaluated by a third-party doctor, with a score ranging from 1 to 5. The smaller the score, the more significant the improvement compared to before the operation. The satisfaction of patients with the surgical outcome was evaluated and classified into four levels: very satisfied, satisfied, dissatisfied, and very dissatisfied.Results:A total of 25 female patients were enrolled, aged 20 to 38 years, with an average age of 27.1 years. All procedures were completed successfully, with a mean operative time of (25.4±4.2) minutes. Postoperative localized swelling of varying degrees was observed. Follow-up ranged from 6 to 18 months, with nasal contour and curvature stabilizing by 6 months postoperatively. No complications, such as infection, nasolacrimal duct, lacrimal sac, medial canthal ligament, nerve injuries, or sensory disturbances, were reported. Two cases exhibited mild nasal bone widening at the 6-month follow-up, though no surgical revision was requested. Significant improvement in external nasal morphology was achieved in all patients, with high satisfaction rates. The patients satisfaction survey showed that 18 cases (72%) were very satisfied and 7 cases (28%) were satisfied with the surgical outcome. GAIS scores reflected positive evaluations [(1.24±0.51) points].Conclusion:The ultrasonic bone scalpel for nasal osteotomy offers the advantages of high-precision cutting and efficient hemostasis. It is highly effective in reshaping the nasal contour, with shorter osteotomy time, reduced intraoperative bleeding, and a lower postoperative complication rate. This study provides some insights into plastic surgeons in optimizing nasal bone modification strategies.

Objective:To evaluate the efficacy and safety of remedial pedicled rectus abdominis myocutaneous flap transplantation for breast reconstruction.Methods:This retrospective study included 23 female breast cancer patients who underwent autologous breast reconstruction with a remedial pedicled rectus abdominis myocutaneous flap at Hunan Cancer Hospital from June 2022 to June 2023. The patients' ages ranged from 24 to 56 years, with a mean age of (43.2±1.3) years. All patients had previously undergone mastectomy and tumor resection before receiving the remedial pedicled rectus abdominis myocutaneous flap reconstruction. Follow-up was conducted through outpatient visits and telephone interviews, with a median follow-up period of 10 (6-15) months. Observation indicators included survival rate of flaps, patient satisfaction rate and aesthetic outcomes. Adverse reactions including but not limited to flap contracture and deformation, during and following the surgical procedure were also recorded.Results:The remedial pedicled rectus abdominis myocutaneous flap technique was utilized for autologous breast reconstruction in 23 patients. Specifically, this approach was chosen due to two primary reasons: the perforator distance from the vascular pedicle being excessively long in 18 cases, and suboptimal characteristics of the main pedicle in 5 cases. Two types of flap configurations were employed. For 15 patients, a unilateral remedial pedicled rectus abdominis myocutaneous flap was used, with an average flap size of (21.5±0.8) cm in length and (11.2±1.3) cm in width. All flaps demonstrated adequate blood supply without the need for additional vascular anastomosis. For the remaining 8 patients, a combination of a unilateral remedial pedicled rectus abdominis myocutaneous flap and a contralateral free lower abdominal flap was utilized, resulting in an average flap size of (29.3±0.7) cm in length and (12.0±1.8) cm in width. In these cases, the inferior epigastric vessels of the free lower abdominal flap were successfully anastomosed to the internal thoracic vessels of the recipient site, ensuring all flaps survived postoperatively. The survival rate of flaps in 23 patients was 100% (23/23), and the patient satisfaction rate was 100% (23/23). Postoperative evaluation revealed that the reconstructed breasts exhibited satisfactory shape and texture, with no instances of flap contracture or deformation. The reconstructed breasts were largely symmetrical with the contralateral side, leaving only linear scars at the donor and recipient sites. Importantly, there was no significant impact on abdominal wall function, and no adverse reactions such as flap contracture or impaired abdominal wall function were observed in any of the patients.Conclusion:When the characteristics of the perforating vessels in the lower abdomen are suboptimal, the use of a remedial pedicled rectus abdominis myocutaneous flap technique for breast reconstruction can ensure satisfactory outcomes and significantly enhance surgical safety.

Chinese Pediatric Emergency Medicine 2025;32(9):668-673
Objective:To evaluate the validity of spectral entropy as a quantitative tool for assessing sedation depth in mechanically ventilated pediatric patients and to investigate its prognostic value in predicting clinical outcomes among children with pneumonia requiring early sedation.Methods:A total of 31 mechanically ventilated children admitted to the Pediatric Intensive Care Unit of Shengjing Hospital of China Medical University from December 2021 to December 2022 were enrolled.Patients were stratified into deep sedation (Ramsay score ≥5) and light sedation (Ramsay score ≤4) groups.For children with concurrent pneumonia,prognosis was evaluated using a modified PIRO (Predisposition,Insult,Response,Organ dysfunction) score,and patients were further classified into favorable-prognosis group and poor-prognosis group.Clinical characteristics,outcomes,and spectral entropy values were compared across groups.Receiver operating characteristic (ROC) curve analysis was performed to assess the prognostic predictive capacity of spectral entropy and Ramsay scores.Results:Spectral entropy exhibited a strong negative correlation with Ramsay scores ( r s2=-0.787, P < 0.001).The deep sedation group demonstrated significantly lower spectral entropy values compared to the light sedation group (34.0±1.0 vs.52.7±6.3, P<0.001).Among children with pneumonia,the favorable-prognosis group showed higher spectral entropy values than the poor-prognosis group (49.5±8.0 vs.42.1±10.4, P=0.047).Additionally,the hospitalization time of the poor-prognosis group was higher than that of the favorable-prognosis group [20.5(9.0,36.0)days vs.14.0(12.0,18.0)days],although the difference was not statistically significant ( P=0.191).Mechanical ventilation duration was significantly shorter in the favorable-prognosis group versus the poor-prognosis group [(151.7±41.2)hours vs.(414.9±264.1)hours, P=0.012] .Modified PIRO scores correlated positively with Ramsay scores ( r s2=0.367, P=0.042),and negatively with spectral entropy ( r s2=-0.363, P=0.045).ROC analysis revealed that Ramsay scores (AUC=0.329,sensitivity 50.0%,specificity 84.2%) and spectral entropy (AUC=0.715,sensitivity 100.0%,specificity 50.0%) provided statistically significant prognostic discrimination ( P<0.05),with optimal cutoff values of 4.5 and 34.6,respectively. Conclusion:Spectral entropy correlates robustly with Ramsay scores,demonstrating its utility as an objective,quantitative tool for monitoring sedation depth in mechanically ventilated children.Furthermore,spectral entropy shows potential as a direct and reliable electrophysiological biomarker for predicting clinical outcomes in pediatric pneumonia patients receiving early sedation.
