BackgroundPatients with schizophrenia experience low quality of life， and internalized stigma is considered an important indicator for quality of life， while the mediating role of self-esteem and severity of negative symptoms in the relationship between internalized stigma and quality of life remains underexplored. ObjectiveTo examine the mediating role of self-esteem and severity of negative symptoms in the relationship between internalized stigma and quality of life， so as to provide references for improving their quality of life. MethodsA total of 342 patients with schizophrenia who were hospitalized in 6 hospitals in Xiangyang City， Siping City and Changchun City from April to September 2023 were included， and all of whom met the diagnostic criteria for schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10）. Internalized Stigma of Mental Illness Scale （ISMI）， Schizophrenia Quality of Life Scale （SQLS）， Self-Esteem Scale （SES） and negative symptom subscale of Positive and Negative Symptom Scale （PANSS） were administered to all patients. Spearman correlation analysis was adopted to determine correlations between the different scales. A structural equation modeling was constructed using Amos 28.0， and Bootstrap method was employed to verify the mediating effect of self-esteem and negative symptom severity in the association between internalized stigma and quality of life. ResultsA total of 309 patients （90.35%） completed questionnaires in this study. The ISMI score of schizophrenia patients was positively correlated with both SQLS score and the PANSS negative symptom subscale score （r=0.612， 0.492， P<0.01）， while was negatively correlated with SES score （r=-0.513， P<0.01）. The SQLS score was negatively associated with the SES score （r=-0.555， P<0.01） and positively associated with PANSS negative symptom subscale score （r=0.672， P<0.01）. The SES score was negatively correlated with PANSS negative symptom subscale score （r=-0.433， P<0.01）.The total effect value of internalized stigma on quality of life was 0.746 （95% CI： 0.680~0.806）. Self-esteem and severity of negative symptoms independently mediated the relationship between internalized stigma and quality of life， and the indirect effect values were 0.151 （95% CI： 0.062~0.254） and 0.126 （95% CI： 0.047~0.205）， accounting for 20.24% and 16.89% of the total effect， respectively. In addition， a chained mediation effect of self-esteem and quality of life was also demonstrated， the indirect effect value was 0.102 （95% CI： 0.049~0.165）， accounting for 13.67% of the total effect）. ConclusionInternalized stigma in patients with schizophrenia patients can not only directly affect the quality of life， but also indirectly affect the quality of life of patients through either separate or chained mediation of self-esteem and the severity of negative symptoms. ［Funded by Hubei Provincial Undergraduate Innovation and Entrepreneurship Project （number， S202410519027）］

Objective To explore the predictive value of systolic pulmonary artery pressure (SPAP) on autonomic nerve excitation in patients with valvular disease, so as to provide reference for the formulation of clinical intervention plans. Methods The clinical data of patients with valvular disease who received surgical treatment in the General Hospital of Northern Theater Command from August 28, 2020 to February 3, 2021 were prospectively collected. According to the standard deviation of normal-to-normal R-R intervals (SDNN) of the heart rate variability (HRV) of the long-range dynamic electrocardiogram (ECG) 7 days before the operation, the patients were divided into three groups: a sympathetic dominant (SE) group (SDNN≤50 ms), a balance group (50 ms

Objective:To explore the risk factors of ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children.Methods:A retrospective case-control study was conducted to analyze the clinical data of 158 children with unstable lateral humeral condyle fractures admitted to Anhui Provincial Children′s Hospital from January 2022 to August 2023, including 102 males and 56 females, aged 1-14 years [5(4, 8)years]. The patients were divided into reduction success group ( n=136) and reduction failure group ( n=22) according to the results of ultrasound-guided closed reduction. The gender, age, body mass index, injury side, time from injury to surgery, direction of sagittal plane displacement of the fracture fragment, Milch classification, Song classification, concomitant subcutaneous bruising or not, nighttime surgery or not, surgeons′ lack of experience or not, and concomitant elbow dislocation or not were recorded in both groups. Univariate analysis and binary Logistic regression analysis were used to evaluate and identify the independent risk factors for ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children. Results:Univariate analysis showed that there were significant differences in the time from injury to surgery, direction of sagittal plane displacement of the fracture fragment, and surgeons′ lack of experience or not between the reduction success group and reduction failure group ( P<0.01), while there were no significant differences in gender, age, body mass index, injury side, Milch classification, Song classification, concomitant subcutaneous bruising or not, nighttime surgery or not, or concomitant elbow dislocation or not between the two groups ( P>0.05). Binary Logistic regression analysis showed that the time from injury to surgery≥5 days ( OR=1.47, 95% CI 1.17, 1.86, P<0.01), sagittal anterior displacement of the fracture fragment ( OR=7.07, 95% CI, 1.79, 27.98, P<0.01) and surgeons′ lack of experience ( OR=4.67, 95% CI, 1.21, 18.05, P<0.05) were significantly correlated with ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children. Conclusion:The time from injury to surgery ≥5 days, sagittal anterior displacement of the fracture fragment and surgeons′ lack of experience are the independent risk factors for ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children.

OBJECTIVE: To investigate the incidence and potential risk factors associated with postoperative spinal epidural hematoma (SEH) following anterior cervical spine surgery (ACSS). METHODS: A retrospective analysis was conducted on the clinical data of patients who underwent ACSS for cervical spondylosis at Peking University Third Hospital between March 2013 and February 2022. Patients who developed postoperative SEH were categorized as the SEH group, while those in the cohort without SEH were randomly selected as the non-SEH group by individually matching with the same operator, same gender, same surgery year, and similar age (±5 years) at a ratio of 4 ∶ 1. The general condition, preoperative comorbidities, anticoagulant or antiplatelet therapy, preoperative coagulation and platelet counts, American society of Anesthesiologists physical status classification, cervical spondylosis classification, preoperative modified Japanese Orthopaedic Society score and cervical disability index score, surgical modality, surgical segment levels, ossification of the posterior longitudinal ligament among the surgical level, surgery duration, estimated blood loss, postoperative drainage volume, preoperative mean arterial pressure, mean arterial pressure during postoperative awakening periods, hospital stay and hospitalization cost were compared between the two groups. A bivariate Logistic regression model was applied to screen out the independent risk factors and calculate the odds ratios of indicators associated with SEH. Receiver operating characteristic curve and area under the curve (AUC) were used to describe the discrimination ability of the indicators. RESULTS: A total of 85 patients were enrolled in the study, including 17 patients in the SEH group and 68 patients in the non-SEH group. Seventeen patients with SEH underwent hematoma evacuation, and all of them were successfully treated and discharged from the hospital. Corpectomy (OR=7.247; 95%CI: 1.962-26.766; P=0.003) and the highest mean arterial pressure during awakening (OR=1.056; 95%CI: 1.002-1.113; P=0.043) were independent risk factors for SEH. The AUC values were 0.713 (95%CI: 0.578-0.848) and 0.665 (95%CI: 0.51-0.82) respectively. The patients with SEH had longer hospital stays (P < 0.001) and greater hospitalization costs (P=0.035). CONCLUSION Corpectomy and elevated maximum mean arterial pressure during awakening are independent risk factors for the development of postoperative SEH following ACSS. High-risk patients should be closely monitored during the perioperative period.

Objective:To evaluate the feasibility of using cortical bone trajectory (CBT) screws in the osteoporotic thoracolumbar fixation by comparing the bone CT values at the bone-screw interface between traditional trajectory (TT) screws and CBT screws in patients with different bone densities.Methods:The high-resolution CT imaging data of thoracolumbar segments following thoracic or lumbar spine fractures from April 2020 to October 2022 were collected at The Second Hospital Affiliated to Wenzhou Medical University for retrospective analysis. They were divided into 3 groups: a normal bone mass group, an osteopenia group and an osteoporosis group. From each group 30 cases were chosen (90 cases in total, 36 males and 54 females). All the data were imported into Mimics 18.0 for three-dimensional bone reconstruction in which placement of TT and CBT screws was simulated on the vertebrae from T10 to L2 (non-fractured vertebrae). Regions of interest (ROI) where each simulated screw intersected the bone were segmented to measure their CT bone values. For each vertebra in each group, the relative difference percentage in average CT value of ROI between TT and CBT screws was calculated. The CT values of ROI were compared in the same group between TT and CBT screws from T10 to L2; the CT values of ROI were compared in the same screws among the 3 groups from T10 to L2; the CT values of ROI were compared between the CBT screws in the osteopenia and osteoporosis groups and the TT screws in the normal bone mass group; the relative difference percentages in average CT value of ROI between CBT and TT screws were compared between the 3 groups from T10 to L2.Results:The average CT value of ROI for CBT screws was significantly higher than that for TT screws from T10 to L2 in every group ( P< 0.001); as for the CT values of ROI for CBT and TT screws from T10 to L2, the osteoporosis group0.05). At T10, T12, and L1, the relative difference percentage in average CT value of ROI between CBT and TT screws was significantly higher in the osteopenia and osteoporosis groups than that in the normal bone mass group ( P<0.05), but there was no such a difference between the osteopenia and the osteoporosis groups ( P>0.05). At T11 and L2, there was no significant difference between the 3 groups in the relative difference percentage in average CT value of ROI between CBT and TT screws ( P>0.05). Conclusions:As bone mass decreases, both CBT and TT screws lead to a significant decrease in the bone density at the bone-screw interface. In patients with osteoporosis, CBT screws can still lead to a higher bone density at the bone-screw interface than TT screws, thus providing a higher strength at the bone-screw interface.

Objective : To investigate the natural evolution of the sciatic bone thickness in pediatric untreated unilateml developmental dysplasia of the hip ( DDH)aged 1-15 years. Methods: 329 cases of DDH childrn aged 1-15 years with unilateral disloeation were retrospectively reconled. The connection lines were defined on the coronal plane or axial plane of CT. The connection lines of the Y ⁃shaped cartilage center on both sides were line H , the connection lines of the lowest edge of the ischia on both sides were line b , and the middle part of the two lines were divided into Zone 1 and Zone 2. Zone 1 represented the marginal area , and Zone 2 represented the central area. The thickness of ischium , epiphyseal plate , iliac bone thickness and epiphyseal quotient of femoral head on both sides were measured and compared. Results : In coronal CL1 ⁃CL4 , the ischial thickness gradually increased with age from 1 to 10 years old , and decreased from 11 to 15 years old. The range of ischial thickness of CL1 ⁃CL4 was 2. 1 - 16. 7 mm , 3. 3 - 18. 9 mm , 2. 4 - 13. 6 mm and 3. 0 - 14. 9 mm , respectively. The width of the epiphyseal plate in coronal position , the width of the epiphyseal plate in axial position , and the thickness of the iliac bone in the affected side were greater than those in the opposite side and had statistical differences. In the correlation test of ischial thickness with age and degree of dislocation , the thickness of ischial bone in coronal and axial positions was moderately correlated with age ( r = 0. 413 - 0. 570 , P < 0. 05) , and had no correlation with the degree of dislocation ( r = 0. 024 - 0. 073 , P > 0. 05) . In the correlation tests of ischial thickness and epiphyseal thickness CD , epiphyseal quotient , coronal iliac thickness IL on the affected side , the thickness of ischial bone in different parts and sections were positive ( r = 0. 427 - 0. 681 , P < 0. 05) , and the thickness of ischial bone was negatively correlated with the epiphyseal quotient ( r = 0. 130 - 0. 241 , P < 0. 05) . Conclusion The ischial thickness in coronal zone 1 and zone 2 of 1 - 10 years old children with unilateral DDH increased at a stable rate with age , and the growth rate decreased gradually in 11 - 15 years old. The thickness of ischia on the affected side in different sections and areas were greater than that on the opposite side. The difference in the central area of the hip joint was greater than that in the marginal area. The thickness of ischia was positively correlated with acetabular cartilage index , epiphyseal plate thickness , and coronal iliac bone thickness.

Objective:To establish the normal reference value of lumbar bone mineral density (BMD) under quantitative CT (QCT) in Chinese healthy adult females and to explore the regional differences.Methods:Total of 35 431 healthy women who met the inclusion criteria of Chinese health quantitative CT big data program were selected in this study. The BMD of the central plane of L 1 and L 2 vertebrae was measured by Mindways′s QCT system, and the mean value was taken. One-way analysis of variance was used to compare the BMD differences of lumbar vertebrae in women of different ages and regions. The subjects were grouped by an age interval of 10 years, and the level of BMD in different regions of the same age group were compaired. Results:The peak BMD of Chinese healthy adult women appeared in the age group of 20-29 years (Northeast China(183.01±24.58) mg/cm 3, North China (188.93±24.80) mg/cm 3, East China (187.54±27.71) mg/cm 3, South China (186.22±33.72) mg/cm 3, Central China (176.33±24.91) mg/cm 3, Southwest China(182.25±28.00) mg/cm 3), and then it decreased with age. The level of BMD in different regions decreased with the age. Before the age of 70 years, BMD in Central and Southwest China was always at a low level((176.23±24.91) to (90.38±28.12) mg/cm 3, 182.25±28.00 to (88.55±25.68) mg/cm 3), lower than those in Northeast China ((183.01±24.58) to (99.69±27.85) mg/cm 3), North China ((188.93±24.80) to (95.89±26.12) mg/cm 3), East China ((187.54±27.71) to (95.65±27.86) mg/cm 3). After 70 years of age, BMD tended to be the same in different regions ( P>0.05). The BMD values in Central China and Southwest China were similar in the age group of 40-60 years ( P>0.05). The BMD values in the health adult femles in the age group of 60 years in different regions of Chinawere all lower than those of bone mass abnormality (all P<0.05). The detection rate of osteoporosis in females over 50 years was the highest in Southwest China (25.65%) and it was the lowest in North China (17.30%). Conclusions:This study establishes reference values of BMD under QCT in healthy Chinese women, which can be used as a reference basis for identifying women with low BMD who are at risk of osteoporosis. The BMD value is the lowest in Southwest China and the highest in South China.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

AIM: To describe the clinical characteristics of 6 premature infants diagnosed as familial exudative vitreoretinopathy(FEVR).

METHODS: From August 2018 to January 2019, the researchers collected six premature cases of FEVR from Xinhua Hospital Affiliated To Shanghai Jiao Tong University School of Medicine. All 6 infants born prematurely had examinations of fundus photography and fluorescein angiograms under anesthesia. Medical history and angiographic features were analyzed retrospectively.

RESULTS: Six infants born prematurely were initially misdiagnosed as retinopathy of prematurity ROP. All underwent injection anti-vascular endothelial growth factor(anti-VEGF)drug into vitreous body cavity subsequently, two of whom were treated with injection anti-VEGF drug into vitreous body cavity twice. Six infants born prematurely had follow-up examinations of fundus photography and fluorescein angiograms with the machine of Retcam digital imaging system under anesthesia, they were eventually diagnosed as FEVR. Then 2 cases were treated with laser photocoagulation, 1 case was treated with injection anti-VEGF drug into vitreous body cavity combined laser photocoagulation, 1 case was treated with injection anti-VEGF drug into vitreous body cavity, 2 cases maintain the follow-up visit.

CONCLUSION: Clinically, premature infants FEVR, tend to be misdiagnosed as ROP initially. If the demarcation line separating the avascular from the vascular retinal regions presents persistent or the condition turns to be worse, more examinations will be required to confirm the diagnosis such as fluorescein angiograms under anesthesia. FEVR is a lifelong disease, its symptoms, if present, typically take a progressive course during childhood and adolescence. Early diagnosis of FEVR is crucial due to its progressive nature and the genetic/familial underpinnings of the condition. The correct identification of those FEVR patients can help them receive timely treatment and genetic counseling for those of child-bearing age.
