ObjectiveThis paper aims to conduct the feature analysis and correlation analysis on the ocular collateral features and differential metabolites in patients with chronic hepatitis B （CHB） complicated by glucose metabolism disorder （GMD），particularly those with the damp-heat syndrome type，by integrating shadowless scleral imaging and metabolomics technologies. MethodsA total of 313 patients were recruited from the Hepatology and Endocrinology Outpatient Departments of Public Health Clinical Center of Chengdu according to the inclusion/exclusion criteria，and they were divided into a CHB group and a CHB complicated by GMD groups （damp-heat syndrome group and non-damp-heat syndrome group）. All patients underwent high-definition ocular image acquisition and feature extraction using an intelligent analysis system for shadowless scleral imaging to analyze the differences in the counting of morphological feature scores of ocular collaterals among groups. By using a digital sampling method，24 patients from each group were randomly selected，along with 20 healthy volunteers，for untargeted metabolomic analysis of peripheral serum. Differential metabolites were identified，statistically analyzed，and subjected to potential biomarker analysis and pathway enrichment. Spearman method was performed to conduct the correlation analysis on the differential ocular collateral features and differential metabolites，followed by correlation network construction. ResultsCompared with those in the CHB group，patients with CHB complicated by GMD showed significant changes in ocular collateral feature scores such as "hillock"，"blood vessels"，and "pale dusky coloration" （P<0.05）. In comparison with those in the healthy group，metabolites including N-acetylglucosamine，acetylhomoserine，and myo-inositol （AUC>0.7） were identified as potential biomarkers for the disease. Compared with those in the CHB complicated by GMD group with non-damp-heat syndrome，patients with damp-heat syndrome exhibited significant changes in feature scores of "plaques"，"yellow coloration"，"spleen"，and "gallbladder" （P<0.05）. In comparison with those in the healthy group，metabolites such as O²′-4a-cyclic tetrahydrobiopterin，theobromine，xanthurenic acid，and L-glutamic acid 5-phosphate （AUC>0.7） were identified as potential biomarkers for the damp-heat syndrome type. The Spearman correlation analysis reveals weak to moderate linear correlations between the differential scleral collateral features and metabolites. By constructing a "disease-syndrome" network of ocular diagnosis and metabolites，"xanthurenic acid-gallbladder" and "theobromine-plaque/yellow coloration" were identified as specific molecular-phenotypic correlated biomarker clusters for CHB complicated by GMD with dampness-heat syndrome. ConclusionPatients with CHB complicated by GMD demonstrate differential ocular diagnostic features and serum metabolites corresponding to disease states and dampness-heat syndrome. These objective biomarkers can guide both clinical syndrome differentiation and medication. The macro-micro integration based on ocular feature clusters and potential metabolic biomarkers offers an innovative approach to a combined traditional Chinese and Western medicine diagnosis and treatment model for this disease.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

OBJECTIVE: To investigate the effect of expansive open-door laminoplasty combined with single lateral mass screw fixation on the posterior longitudinal ligament ossification and cervical instability and its effect on sagittal balance. METHODS: A retrospective analysis of 65 patients with the posterior longitudinal ligament with cervical instability from May 2012 to July 2018 was conducted. The patients were divided into two groups according to the surgical method. Thirty-four patients were treated with open-door laminoplasty including 19 males and 15 females, aged 49 to 60 years old with an average age of (54.4±4.77) years old;symptoms lasted 8 to 39 months with an average of (21.0±8.2) months. Thirty-one patients were treated with single-door laminoplasty combined with single mass screw fixation including 17 males and 14 females, aged 50 to 59 years old with an average age of (55.4±3.2) years;symptoms lasted 7 to 48 months with an average of (23.7±13.1) months. General information of the two groups, including operation time, intraoperative blood loss, and postoperative complications was recorded. Sagittal vertical axis(SVA), C₀-C₂ and C₂-C₇ cobb angle were measured by X-ray before operation and at the last follow-up. Clinical efficacy was evaluated using the Japanese Orthopaedic Association(JOA) score. RESULTS: Surgery was successful in all patients. The operation time (109±15) min in the single-door laminoplasty combined with lateral mass screw fixation group was longer than that in the single-door group(128±16) min(P<0.05). There was no significant difference in intraoperative blood loss, postoperative axial symptoms and follow-up time between two groups(P>0.05). At the latest follow-up, both groups showed significant improvement in the motor and sensory components of the JOA score and the total JOA score compared to pre-surgery(P<0.05) and no significant change in bladder function score(P>0.05). There was no significant difference between two groups(P>0.05). At the latest follow-up, the C₀-C₂ Cobb angle increased in both groups compared to preoperative and more the single-door laminoplasty group(P<0.05). The angle of the C₂-C₇ Cobb angle decreased in both groups, and the reduction was greater in the single-door laminoplasty combined with lateral mass screw fixation group(P<0.05). There was a significant increase in C₂-C₇ SVA in the single-door laminoplasty group(P<0.05) and no significant change the single-door laminoplasty combined with lateral screw fixation group(P>0.05). CONCLUSION Posterior cervical laminoplasty with unilateral lateral mass screw fixation combined with single-door vertebral plate shaping surgery improves the neurological function and quality of life in patients with cervical spondylotic myelopathy complicated by ossification of the posterior longitudinal ligament and cervical instability. Compared with single-door vertebral plate shaping surgery, postoperative cervical lordosis and forward-tilt can be improved.

OBJECTIVES: To investigate the application value of thromboelastography (TEG) in assessing coagulation function in children with severe hemophilia A (HA) after emicizumab (EMI) therapy. METHODS: A retrospective analysis was performed on the activated partial thromboplastin time (APTT) and TEG testing results of 17 children with severe HA before and after EMI treatment at Shenzhen Children's Hospital from January 2023 to July 2024. Correlation analysis was conducted between coagulation factor VIII (FVIII) equivalent activity and reaction time (R value) measured by TEG. RESULTS: After EMI treatment, the mean bleeding rate for children with severe HA was 1.6 events per year, with 15 children (88%) without spontaneous bleeding or joint bleeding. The children with severe HA showed a significant reduction in APTT after EMI treatment (P<0.05), with a significantly shorter APTT than the normal control group (P<0.05). There was no correlation between APTT and FVIII equivalent activity after treatment (P>0.05). After EMI treatment, TEG parameters, including R value, kinetic time, alpha angle (α), maximum amplitude, clot strength, and coagulation index, shifted from a hypocoagulable state before treatment to a nearly normal state after treatment (P<0.05). The R value demonstrated a strong negative correlation with FVIII equivalent activity (r=-0.758, P<0.05). CONCLUSIONS The bleeding condition of children with severe HA can be effectively controlled after EMI treatment. Routine APTT testing cannot reflect true coagulation function, whereas TEG testing is clinically valuable in assessing the coagulation function of children with severe HA undergoing EMI treatment.

OBJECTIVES: To investigate the genomic characteristics and prognostic factors of juvenile myelomonocytic leukemia (JMML) with RAS mutations. METHODS: A retrospective analysis was conducted on the clinical data of JMML children with RAS mutations treated at the Hematology Hospital of Chinese Academy of Medical Sciences, from January 2008 to November 2022. RESULTS: A total of 34 children were included, with 17 cases (50%) having isolated NRAS mutations, 9 cases (27%) having isolated KRAS mutations, and 8 cases (24%) having compound mutations. Compared to children with isolated NRAS mutations, those with NRAS compound mutations showed statistically significant differences in age at onset, platelet count, and fetal hemoglobin proportion (P<0.05). Cox proportional hazards regression model analysis revealed that hematopoietic stem cell transplantation (HSCT) and hepatomegaly (≥2 cm below the costal margin) were factors affecting the survival rate of JMML children with RAS mutations (P<0.05); hepatomegaly was a factor affecting survival in the non-HSCT group (P<0.05). CONCLUSIONS Children with NRAS compound mutations have a later onset age compared to those with isolated NRAS mutations. At initial diagnosis, children with NRAS compound mutations have poorer peripheral platelet and fetal hemoglobin levels than those with isolated NRAS mutations. Liver size at initial diagnosis is related to the prognosis of JMML children with RAS mutations. HSCT can improve the prognosis of JMML children with RAS mutations.

Objective:To analyze the epidemiological characteristics of mumps in China under the immunization strategies of different doses of mumps-containing vaccines(MuCV) by analyzing the national mumps surveillance data from 2020 to 2023.Methods:Based on the national mumps surveillance data from 2020 to 2023, a comparative analysis was conducted on the mumps incidence and the distribution characteristics of mumps cases in time, region and population in the three different periods of 2004-2007 (without MuCV implementation), 2008-2019 (one-dose MuCV implementation) and 2020-2023 (two-dose MuCV implementation) in China.Results:From 2020 to 2023, the annual incidence rate of mumps was 6.48-9.20/100 000, and the annual number of reported cases was 91 303-129 120 cases. After the implementation of the 2-dose MuCV immunization strategy, the epidemiological characteristics of mumps in China have changed to some extent. Compared with the period of 2004-2007 and 2008-2019, the traditional seasonal epidemic pattern of mumps disappeared from 2020 to 2023, with no obvious epidemic peak throughout the year. There was no significant regional difference in the incidence of mumps. Children and adolescents under 15 years of age were the main population of mumps (accounting for 85.46%), of which children aged 5-9 years accounted for 45.07%. Compared with the period of 2004-2007 and 2008-2019, the proportion of mumps cases in the 0-4 years old group showed an increasing trend, the proportion of mumps cases in the 10-14 years old group showed a decreasing trend, and the proportion of adult cases over 40 years old also increased from 2020 to 2023. The age group with the highest incidence of mumps was found to have shifted from 7 years old to 4 years old.Conclusions:The 2-dose MuCV immunization strategy has effectively reduced the incidence of mumps in China. It is necessary to strengthen the surveillance of mumps in kindergartens and primary school children.

Objective:To summarize the clinical characteristics, treatment, and prognosis of children with anti-GT1a antibody-positive Guillain-Barré syndrome (GBS).Methods:A case series study was conducted, including 25 children diagnosed with serum anti-GT1a antibody-positive GBS at Guangzhou Women and Children′s Medical Center from March 2019 to December 2024. Clinical data, treatment protocols, and follow-up outcomes were analyzed. Mann Whitney U test was used to compare the changes in Hughes functional grading scale (HFGS). Results:A total of 25 children included 12 boys and 13 girls, and the age at first onset was (71±8) months. There were 16 children (64%) had preceding infections, and of which 13 children had predominantly respiratory tract infections. At disease peak, neurological manifestations included limb weakness (21 cases (84%)), bulbar palsy (13 cases (52%)), drowsiness (7 cases (28%)), limb pain (9 cases (36%)), ataxia (6 cases (24%)), respiratory muscle paralysis (5 cases (20%)), ophthalmoplegia (5 cases (20%)), and unilateral facial nerve palsy (4 cases (16%)). Cerebrospinal fluid analysis in 23 children revealed albuminocytological dissociation in 18 children. All 25 children underwent whole-spine magnetic resonance imaging (MRI), demonstrated spinal nerve root enhancement in 18 children, with leptomeningeal enhancement combined with spinal nerve root enhancement in 1 child. Electromyography in 16 children showed 15 children abnormality, of which demyelinating lesions in 8 children, mixed demyelinating-axonal changes in 4 children, and pure axonal involvement in 3 children. Intravenous immunoglobulin (IVIG) was administered to 21 cases (84%), of which 3 children required mechanical ventilation and blood purification (plasma exchange in 2 children and immunoadsorption in 1 child) due to disease progression. Four children (16%) received intravenous methylprednisolone (IVMP) instead of IVIG, with 1 child requiring ventilatory support due to respiratory muscle paralysis, and the tracheal tube was removed after continued sequential IVMP treatment. The hospitalization duration of 25 children was (23±3) d. At discharge, HFGS was 1.6 (0.6, 2.7) score. At a follow-up of 12 (4, 18) months, HFGS was 0.1 (0.0, 0.5) score, and higher than that at discharge ( Z=4.38, P<0.05). Two children relapsed but achieved remission after IVIG retreatment with no recurrence during 1-year follow-up. Conclusions:Anti-GT1a antibody-positive GBS in children predominantly presents with limb weakness and bulbar palsy, occasionally complicated by respiratory failure in the acute phase. Demyelinating neuropathy and spinal nerve root enhancement on MRI are characteristic. IVIG therapy yields favorable outcomes, with low residual disability. Relapses are rare but manageable with re-treatment.

Objective:To investigate the correlation between vasoactive-inotropic score and 30-day mortality after surgery in acute Stanford type A aortic dissection(ATAAD) patients.Methods:The clinical data of 242 patients with ATAAD who underwent surgical treatment was retrospectively analyzed between November 2015 and May 2024. There were 172 males and 70 females. The average age was(53.1±11.9) years, ranging from 28 to 85 years. Patients were divided into death group(18 cases) and survival group(224 cases) according to the 30-day outcomes after surgery. The VIS at different time points and perioperative indexes of two groups of patients were analyzed, and multivariate logistic regression was used to analyze the risk factors of 30-day mortality after surgery in ATAAD patients. The receiver operating characteristic curve( ROC) was drawn to evaluate the predictive value of vasoactive-inotropic score. Results:Among 242 ATAAD patients, 18 patients died within 30 days after surgery, with a mortality rate of 7.4%. The age, incidence of pericardial tamponade/cardiogenic shock, incidence of malperfusion syndrome, cardiopulmonary bypass time, red blood cell transfusion intraoperative and in 24 hours postoperatively, ventilator assisted time, and incidence of major postoperative complications of patients in the death group were significantly higher than those in the survival group( P<0.05). The VIS of the death group was significantly higher than that of the survival group at all time points( P<0.05). The area under the receiver operating characteristic curve( AUC) of VIS for predicting death at each time point was greater than 0.500( P<0.05), with the highest AUC(0.906) of the second 24 hours(VISmax48h) in ICU. The optimal cut off value was determined to be 9, with a sensitivity of 0.944 and a specificity of 0.821. Logistic regression analysis showed that the VISmax48h of the second 24 hours in ICU was an independent risk factor for 30-day mortality after surgery in ATAAD patients( OR=1.462, 95% CI: 1.230-1.737, P<0.05). Conclusion:When VISmax48h≥9, patients with ATAAD have an increased risk of mortality after surgery. VISmax48h, cardiopulmonary bypass time, and red blood cell transfusion intraoperative in 24 hours postoperatively are independent risk factors for the 30-day mortality of ATAAD patients.

Purpose: Irreversible electroporation (IRE) is a promising alternative treatment for low-intermediate-risk localized prostate cancer. In this systematic review we aim to evaluate the safety profile and functional and oncological outcomes of this new technique. Materials and Methods: A systematic review of the literature was performed on PubMed, EMBASE, and Scopus up to 24 August 2023. Nineteen studies were analyzed, including 12 prospective studies and 7 retrospective studies. A total of 1,452 patients underwent IRE as the sole primary treatment modality. Results: The in-field clinically significant prostate cancer rate was reported between 0%–15.6% in the repeat biopsy. The retreatment rate was reported from 8% to 36.6%. The 3 years failure-free survival was presented between 90%–96.8%. The post-operative pad-free rate ranged between 96.7%–100%. Greater heterogeneity exists considering the change in erectile function. The most common reported complications were urinary tract infection and hematuria. Major complications were rare. Conclusions These results underline that IRE achieves favorable oncological control with an excellent safety profile, in the meantime preserving patients’ urinary and erectile function
