Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Objective:To investigate the efficacy of radiotherapy in patients with advanced esophageal cancer receiving first-line chemoimmunotherapy.Methods:A retrospective analysis was conducted on the data of 137 patients with Stage Ⅳ esophageal squamous cell carcinoma (ESCC) treated at our hospital from January 2018 to May 2023. These patients were divided into two groups: a group treated with first-line chemoimmunotherapy combined with radiotherapy (chemoimmunotherapy + radiotherapy group, n = 43) and a group treated with only chemoimmunotherapy ( n = 94). Inverse probability of treatment weighting (IPTW) was applied to balance baseline characteristics between the groups. With overall survival (OS) and progression-free survival (PFS) as study endpoints, the survival data were analyzed using the Kaplan-Meier method, the log-rank test, and the Cox regression method. Results:Before calibration, the chemoimmunotherapy + radiotherapy group significantly outperformed the sole chemoimmunotherapy group in median PFS (13.6 months vs. 7.0 months; HR: 0.501, 95% CI: 0.309-0.811, P = 0.005). After calibration using the COX proportional-hazards model for age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, smoking history, T/N/M stage, and tumor location, the chemoimmunotherapy + radiotherapy group still had significant advantages in PFS (14.7 months vs. 7.0 months; HR: 0.441, 95% CI: 0.261-0.745, P = 0.002). IPTW analysis further confirmed this trend (13.9 months vs. 7.0 months; HR: 0.492, 95% CI: 0.304-0.795, P < 0.001). Specifically, the median OS of the chemoimmunotherapy + radiotherapy group demonstrated significant improvement in all analyses: pre-calibration (29.5 months vs. 18.0 months; HR: 0.507, 95% CI: 0.297-0.867, P = 0.013), after calibration using the Cox model (27.5 months vs. 16.7 months; HR: 0.470, 95% CI: 0.266-0.830, P = 0.009), and after calibration using IPTW (29.5 months vs. 16.9 months; HR: 0.448, 95% CI: 0.262-0.764, P < 0.001). Conclusions:The combination of radiotherapy and first-line chemoimmunotherapy can significantly improve survival outcomes of patients with advanced ESCC, suggesting its potential as a standard treatment strategy.

Objective To examine the expression levels of inflammatory factors,including IL-6,IL-10,MMP-9,IL-17A,and LDH,in the cerebrospinal fluid(CSF)of patients with spontaneous intracerebral hemor-rhage(sICH),and to investigate their associations with disease severity and clinical outcomes.Methods A total of 168 patients with sICH admitted to Tangshan GongRen Hospital between January 2023 and January 2025 were prospectively enrolled as the study group,while 30 non-sICH patients who underwent lumbar puncture during the same period served as the control group.Levels of inflammatory factors in CSF were compared between the two groups.Spearman's rank correlation analysis was performed to assess the association between inflammatory factor levels and clinical severity in sICH patients.Binary logistic regression analysis was conducted to identify independent predictors of sICH prognosis.Receiver operating characteristic(ROC)curve analysis was employed to evaluate the prognostic value of these inflammatory factors in sICH.Results The levels of IL-6,IL-10,MMP-9,IL-17A,and LDH in the CSF of patients with sICH were significantly higher than those in non-sICH patients(all P<0.05).Furthermore,among sICH patients,these biomarker levels exhibited a graded increase according to disease severity:severe>moderate>mild(all P<0.05).Spearman correlation analysis revealed significant positive correlations between CSF levels of IL-6,IL-10,MMP-9,IL-17A,and LDH and the NIHSS scores,with correlation coefficients(r)of 0.686,0.553,0.685,0.593,and 0.695,respectively(all P<0.05).When comparing the prognoses of sICH patients,hematoma size,NIHSS score,and CSF levels of IL-6,IL-10,MMP-9,IL-17A,and LDH were significantly higher in the deceased group than in the survival group(P<0.05),whereas ApoA1 levels were lower in the deceased group(P<0.05).Logistic regression analysis revealed that hematoma size,NIHSS score,and elevated CSF levels of IL-6,IL-10,MMP-9,IL-17A,and LDH were independent risk factors for mortality in sICH patients(P<0.05).ROC curve analysis showed that the AUC values for CSF IL-6,IL-10,MMP-9,IL-17A,and LDH in predicting sICH prognosis were 0.794,0.754,0.670,0.717,and 0.683,respectively.Notably,the combination of CSF inflammatory markers with hematoma size and NIHSS score yielded an AUC of 0.993,demonstrating significantly greater predictive accuracy than CSF inflammatory markers alone(P<0.05).Conclusions The levels of inflammatory factors in the CSF,including IL-6,IL-10,MMP-9,IL-17A,and LDH,were elevated in patients with sICH and positively correlated with disease severity.Combining CSF inflammatory markers with the NIHSS score and hematoma size improved the predictive accuracy for sICH prognosis.

OBJECTIVE To explore the value of bronchoalveolar lavage fluid(BALF)metagenomic next generation sequencing(mNGS)technique in diagnosis of the pulmonary cryptococcosis patients with different clinical features so as to raise the clinicians' awareness of the diagnosis of pulmonary cryptococcosis with BALF-mNGS.METHODS Totally 73 patients with pulmonary cryptococcosis and 73 non-pulmonary cryptococcosis patients who were treated in Wenzhou People's Hospital from Jan.2021 to May 2024 were recruited as the research subjects.The clinical data including baseline data,complications,clinical manifestations,clinical laboratory test data,ima-ging findings and serological test data were collected from the patients.The sensitivity and specificity of BALF-mNGS in diagnosis of the pulmonary cryptococcosis were observed,and the difference in the sensitivity in diagno-sis of the patients with various clinical features was analyzed.RESULTS A total of 73 patients with pulmonary cryp-tococcosis were enrolled in the study,44 of whom were male,and 29 were female;62 were positive for BALF-mNGS,11 were negative;all of the 73 non-pulmonary cryptococcosis patients were tested negative for BALF-mNGS,the sensi-tivity of the BALF-mNGS test was 84.93％,with the specificity 100.00％,the positive predictive value 100.00％,the negative predictive value 86.95％.Totally 45 patients had the symptoms of cough and expectoration,42 of whom were positive for BALF-mNGS,the test sensitivity of the patients with the symptoms of cough and expectoration was 93.33％,higher than that of the patients without the symptoms of cough and expectoration(P＜0.05).Totally 31 pa-tients had the lesion site of right lung,30 of whom were positive for BALF-mNGS,and the test sensitivity of the patients with lesion site of right lung was 96.77％,higher than that of the patients with the lesion site of left lung or both lungs(P＜0.05).Totally 44 patients had multiple lesions,41 of whom were positive for BALF-mNGS,the test sensitivity of the patients with multiple lesions was 93.18％,higher than that of the patients with single lesion(P＜0.05).CONCLUSIONS The sensitivity of the BALF-mNGS is high in diagnosis of the patients with pulmonary cryptococ-cosis,especially for the patients with symptoms of cough and expectoration,lesion site of right lung and multiple lesions.It can be used for the early diagnosis of pulmonary cryptococcosis.

Objective:To develop and validate a Self-care Ability Scale for Arteriovenous Fistula (AVF) in Maintenance Hemodialysis (MHD) patients.Methods:Guided by Orem's self-care theory, the initial item pool of the scale was developed through a literature review, semi-structured interviews, and group discussions. The initial scale was finalized after two rounds of expert consultation using the Delphi method. A convenience sampling method was used to recruit 418 MHD patients using AVF in January 2024 for item analysis, exploratory factor analysis and reliability testing. Another 293 MHD patients using AVF were recruited in March 2024 for confirmatory factor analysis.Results:The self-care ability scale for AVF in MHD patients included four dimensions: knowledge and skills of AVF self-care, willingness and attitude toward AVF self-care, recognition and prevention of AVF complications, and patient self-adjustment and adaptation, comprising 38 items. The content validity index at the scale level was 0.98. Exploratory factor analysis extracted four common factors with a cumulative variance contribution rate of 84.706%. Confirmatory factor analysis indicated good model fit, strong convergent validity, and ideal discriminant validity. The total Cronbach's α coefficient of the scale was 0.987; the split-half reliability coefficient was 0.902, and the test-retest reliability coefficient was 0.979.Conclusions:The Self-care Ability Scale for AVF in MHD patients demonstrates excellent reliability and validity, making it a suitable tool for assessing patients' ability to self-care for their AVF.

A 20-year old female patient diagnosed with right distal tibial giant cell tumor underwent a surgery of resection of distal tibial giant cell tumor, residual cavity liquid nitrogen and electrocauterization inactivation and local arthroplasty on March 17, 2023. Preoperatively a life-size distal tibia model was 3D printed using polylactic acid (PLA) material based on the CT data of patient's distal tibia. Tumor resection was simulated on the model, preserving the surrounding normal bone and articular cartilage unaffected by the tumor. The residual cavity was filled with bone cement and the distal tibial articular surface was shaped using the talar articular surface as a template. The 3D CT data of bone cement was collected and reconstructed. The irregular bone and cartilage defect data were trimmed to form a regular arc shape, which was used as the data for fabricating local arthroplasty prosthesis. The local arthroplasty prosthesis composed of a titanium base and a VE polyethylene liner was 3D printed. During the operation, the test models of titanium alloy base and VE polyethylene liner were used to test the matching degree with the bone and cartilage defect. Minor adjustments were made by removing a portion of the lateral wall of the residual cavity and modifying the base height to achieve proper alignment of the distal tibial articular surface with the talar surface. After confirming a satisfactory fit, the local arthroplasty prosthesis was implanted. Intraoperative fluoroscopic confirmed accurate placement of the prosthesis, good anatomical match with the defect, and restoration of the joint line. The postoperative follow-up was conducted at 2, 4, 12, 20, 48, 72 and 92 weeks. Wound healing was closely monitored, along with radiologic assessment for prosthesis bone ingrowth and local tumor recurrence. Functional evaluations were performed using the AOFAS and Kofoed scoring systems. Postoperatively, the patient experienced plantar numbness and sensory disturbance, which gradually resolved after three weeks. Assisted ambulation began at two weeks postoperatively, and the patient resumed a normal gait by 12 weeks. The Mayo ankle arthroplasty evaluation criteria at postoperative at 48 weeks were excellent. The AOFAS score and Kofoed score were 97 points and 94 points respectively, indicating excellent functional outcomes. Postoperative X-ray indicated that no bone ingrowth was observed at 2 weeks and 4 weeks after the operation, minor ingrowth at 12 weeks postoperatively, significant bone ingrowth at 20 weeks, and complete osseointegration by 48 to 64 weeks. Postoperative CT imaging at 92 weeks confirmed full prosthesis osseointegration, while MRI at 72 weeks showed no evidence of tumor recurrence.

Objective:To evaluate the role of the CC chemokine ligand 2/CC chemokine receptor 2 (CCL2/CCR2) signaling pathway in electroacupuncture (EA)-induced reduction of spinal cord injury (SCI) in rats.Methods:Sixty clean-grade healthy adult female Sprague-Dawley rats, weighing 210-250 g, were divided into 5 groups ( n=12 each) using a random number table method: sham operation group (group S), group SCI, SCI+ Anti-CCL2 group (group SCI+ A), SCI+ EA group (group SCI+ EA), and spinal cord injury+ EA+ rCCL2 group (group SCI+ EA+ R). The SCI model was established using the Allen method in anesthetized animals. Group S only underwent spinous process and laminectomy without damaging the spinal cord. In SCI+ A group, CCL2 neutralizing antibody 50 μg/kg was intrathecally injected at 0, 3 and 6 days after successful development of the SCI model. On the 7th day after the successful development of the SCI model, Jiaji, Dazhui and Mingmen acupoints were stimulated with a depth of 2 mm, voltage of 12-15 mV and frequency of 2 Hz for 30 min once a day for 7 consecutive days in SCI+ EA group. In SCI+ EA+ R group, recombinant rat CCL2 2.5 μg/kg was intrathecally injected at the site of injury at 0, 3 and 6 days after successful development of the SCI model, and the remaining treatments were similar to those in SCI+ EA group. At 1 day before developing the model, 0, 3, 7, 14, 21 and 28 days after developing the model, the mechanical paw withdraw threshold (MWT) and thermal paw withdrawal latency (TWL) were measured, and the motor function was assessed by BBB score. The rats were sacrificed after the final behavioral testing, and their spinal cord tissues were obtained for determination of the expression of CCL2 and CCR2 protein and mRNA (by Western blot or quantitative real-time polymerase chain reaction), the expression of GFAP (by immunofluorescence), contents of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and IL-6 (by enzyme-linked immunosorbent assay) and for examination of the pathological changes (using HE staining). Results:Compared with S group, the MWT and BBB scores were significantly decreased and the TWL was shortened at each time point after developing the model, the expression of CCL2 and CCR2 protein and mRNA and GFAP was up-regulated, and the contents of TNF-α, IL-1β and IL-6 were increased in SCI group ( P<0.05). Compared with SCI group, the MWT and BBB scores were significantly increased, and the TWL was prolonged at 7 days after developing the model in SCI+ A group, the MWT and BBB scores were significantly increased, and the TWL was prolonged at 14 days after developing the model in SCI+ EA group, and the expression of CCL2 and CCR2 protein and mRNA and GFAP was significantly down-regulated, and the contents of TNF-α, IL-1β and IL-6 were decreased in SCI+ A and SCI+ EA groups ( P<0.05). Compared with SCI+ EA group, the MWT and BBB scores were significantly decreased at 14 days after developing the model, the TWL was shortened, the expression of CCL2 and CCR2 protein and mRNA and GFAP was up-regulated, and the contents of TNF-α, IL-1β and IL-6 were increased in SCI+ EA+ R group ( P<0.05). Compared with SCI+ A and SCI+ EA groups, the histopathological injury were significantly attenuated in SCI group, and the histopathological injury was aggravated in SCI+ EA+ R group. Conclusions:The CCL2/CCR2 signaling pathway is involved in the process by which EA reduces SCI, and the mechanism is related to the inhibition of astrocyte activation, thereby reducing the inflammatory response.

Objective:To evaluate the effect of electroacupuncture (EA) on ionotropic purinergic receptor 4 (P2X4R)/nuclear factor-kappa B (NF-κB) signaling pathway during spinal cord injury (SCI) in rats.Methods:Thirty-six clean-grade healthy adult female Sprague-Dawley rats, weighing 210-250 g, were divided into 3 groups ( n=12 each) using a random number table method: sham surgery group (S group), SCI group, and SCI+ EA treatment group (SCI+ EA group). The SCI model was established by the Allen′s method in anesthetized animals. In group S, only the spinous processes and vertebral laminae were resected, but the spinal cord was not injured. On the 7th day after developing the model, EA of Jiaji, Dazhui, and Mingmen lasting 30 min was performed once a day for 7 consecutive days, with a depth of 2 mm, intensity of 12-15 mV, frequency of 2 Hz, in SCI+ EA group. The mechanical paw withdraw threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before developing the model and 3, 7, 14, 21 and 28 days after developing the model, and the motor function was assessed using the Basso-Beattie-Bresnahan (BBB) score. The recovery of motor function was assessed using footprint analysis at 28 days after developing the model. After the final behavioral testing, the rats were sacrificed, and spinal cord tissues were harvested to observe the pathological changes of the spinal cord tissues using hematoxylin-eosin staining, to detect the expression of P2X4R and phosphorylated NF-κB p65 (p-NF-κB p65) (by immunohistochemical analysis and Western blot) and to determine contents of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6 (by enzyme-linked immunosorbent assay). Results:Compared with the baseline measured at 1 day before developing the model, the MWT and BBB scores were significantly decreased and the TWL was shortened at each time point after developing the model in SCI group and SCI+ EA group ( P<0.05). Compared with S group, the MWT and BBB scores were significantly decreased and the TWL was shortened at each time point after developing the model, the expression of P2X4R and p-NF-κB p65 in spinal cord tissues was up-regulated, and the contents of TNF-α, IL-1β and IL-6 were increased in SCI group ( P<0.05). Compared with SCI group, the MWT and BBB scores were significantly increased and the TWL was prolonged at 14, 21 and 28 days after developing the model, the expression of P2X4R and p-NF-κB p65 in spinal cord tissues was down-regulated, and the contents of TNF-α, IL-1β and IL-6 were decreased ( P<0.05), and the pathological damage of spinal cord tissues was alleviated and footprints were reduced in SCI+ EA group. Conclusions:The mechanism by which EA alleviates SCI may be related to the inhibition of the activation of the P2X4R/NF-κB signaling pathway and the reduction in the inflammatory response in rats.

Objective To evaluate the practical application of the Media Fill Test(MFT)in assessing aseptic compounding competency of personnel in Pharmacy Intravenous Admixture Services(PIVAS).Methods A multicenter controlled study was conducted across six tertiary hospitals(center ①-⑥)in China.Participants were divided into an inexperienced group(Group A,n=118)and an experienced group(Group B,n=118),each performing five MFT operations.Positive controls validated medium efficacy.Contamination rates and pass rates were analyzed using chi-square and Fisher's exact tests.Results Valid samples included 584 for Group A and 588 for Group B.The sample pass rate was 66.78%(390/584)in Group A and 91.67%(539/588)in Group B,while personnel pass rates were 46.15%(54/117)and 80.51%(95/118),respectively,with significant intergroup differences(both P<0.01).All centers except Center ⑥ showed significantly higher pass rates in Group B(all P<0.05).Conclusion MFT effectively differentiates technical proficiency levels and is suitable for training evaluation of novice PIVAS staff.

Background and Aims:Obesity is often accompanied by symptoms of disordered eating.Although bariatric metabolic surgery can alleviate these symptoms,there are significant individual differences in postoperative outcomes,and effective predictive indicators are lacking.Liver and kidney function,along with lipid profiles,are closely related to metabolic status and may serve as useful markers for preoperative risk stratification and prognosis prediction.This study was conducted to explore the relationship between preoperative metabolic indicators and symptoms of disordered eating,thereby identifying postoperative recovery patterns among obese patients to support individualized management strategies.Methods:A total of 41 obese patients who underwent sleeve gastrectomy at Shanghai Sixth People's Hospital between September 2020 and June 2023 were enrolled,along with 36 healthy volunteers recruited during the same period.Participants completed the Eating Disorder Inventory-2(EDI-2)questionnaire,and serum samples were collected to assess liver function,kidney function,and lipid levels prior to surgery.The Mantel test was used to analyze correlations between metabolic indicators and EDI-2 scores.Latent profile analysis(LPA)was conducted using the indicators significantly correlated with EDI-2 scores to identify subgroups within the obese cohort.Linear mixed models were then applied to examine the trajectories of postoperative symptom changes across subgroups.Results:Levels of cystatin C,cholinesterase,gamma-glutamyl transferase,triglycerides,and apolipoprotein E were significantly higher in the obese group compared to the healthy group(all P＜0.05),and EDI-2 total score was also significantly elevated(P＜0.05);the prealbumin level in the healthy group was significantly higher than that in the obese group(P＜0.05).These six indicators were positively correlated with EDI-2 score(all r＞0.20,P＜0.05).Based on these markers,the LPA classified the obese group into two subgroups,with subgroup 2 exhibiting higher levels of most metabolic indicators than subgroup 1.During the 18-month postoperative follow-up,both subgroups showed reductions in EDI-2 score,but symptom improvement in subgroup 2 occurred later(month 6)compared to subgroup 1(month 4).Conclusion:Preoperative levels of cholinesterase,gamma-glutamyl transferase,prealbumin,triglycerides,and apolipoprotein E may serve as predictive indicators for improvement in disordered eating symptoms.Recovery patterns after bariatric surgery vary among obese patients with different metabolic profiles,highlighting the need for tailored intervention strategies.
