Objective:To investigate the clinical characteristics of children with cervicothoracic hemivertebra at different ages and evaluate the surgical outcomes of hemivertebra resection.Methods:This retrospective cohort study analyzed clinical and radiographic data of 35 children (under 18 years old) with cervicothoracic hemivertebra who underwent one-stage posterior hemivertebra resection at the Department of Spine Surgery, Second Xiangya Hospital of Central South University, from June 2005 to June 2022. The cohort included 19 males and 16 females, with a surgical age of (9.7±4.1) years (range: 3 to <18 years). Patients were divided into three groups based on initial surgical age: preschool group (≤5 years, n=10), school-age group (6 to 10 years, n=10), and adolescent group (11 to <18 years, n=15). The intraoperative blood loss, operative time, number of fixed vertebrae, and perioperative and postoperative complications were recorded. Radiographic measurements were taken preoperatively, postoperatively, and at final follow-up, including the Cobb angle of the primary curve, curve length, distal curve Cobb angle, neck tilt, shoulder balance, coronal balance, trunk tilt, clavicle angle, head deviation, and local kyphosis. Statistical analyses included one-way ANOVA, Kruskal-Wallis H test, chi-square test, and Fisher′s exact test. Results:The operative time was (333±74) minutes (range:200 to 450 minutes), the intraoperative blood loss was (419±132) ml (range:200 to 650 ml), and the number of fixed vertebrae was (6.0±2.7) segments (range:2 to 12 segments). Preoperatively, the preschool group had a smaller primary curve Cobb angle compared to the adolescent group (33.6°±8.4° vs. 43.0°±9.4°, F=3.394, P=0.046) and distal curve Cobb angle (6.4°±2.4° vs.11.9°±4.5°, F=6.550, P=0.038). The preschool group had better coronal balance ((8.8±4.3) mm vs. (20.2±11.7)mm, F=9.448, P=0.009) and trunk tilt (4.0°±2.0° vs.7.0°±3.0°, F=4.343, P=0.029) than the school-age group. The preschool group had fewer fused vertebrae than the school-age and adolescent groups (3.8±1.6 vs. 7.0±2.6 vs. 6.8±2.6, F=10.480, P=0.005). The preschool group also had less intraoperative blood loss than the adolescent groups ((320±125) ml vs. (480±113) ml, F=8.666, P=0.013). However, no significant differences were found in postoperative and final follow-up measurements of primary and distal curve Cobb angles, neck tilt, shoulder balance, coronal balance, trunk tilt, clavicle angle, head deviation, local kyphosis, or complication rates (all P>0.05). Conclusions:Children with cervicothoracic hemivertebra across different age groups exhibit similar surgical outcomes and complication rates. But the preschool group had fewer fixed segments and less intraoperative blood loss, suggesting that this age group is an ideal time for surgery.

Objective:To investigate the potential diagnostic value of peripheral blood soluble programmed cell death protein 1 (sPD-1) and soluble programmed cell death protein ligand 1 (sPD-L1) in acute rejection (AR) following liver transplantation using a rat model.Methods:A rat liver transplantation AR model was established, with the AR group (Lewis→BN) set as the experimental group (n=6) and the non-AR group (BN→BN) as the control group (n=6). Peripheral blood sPD-1 and sPD-L1 concentrations were measured using enzyme-linked immunosorbent assay (ELISA) at 1 day before transplantation and at 1, 3, and 7 days postoperatively. On postoperative day 7, the expression levels of PD-1 and PD-L1 in liver tissues were detected by immunohistochemistry (IHC). Independent samples t-test and repeated measures ANOVA were used to compare the results between the two groups. Pearson correlation analysis was conducted to evaluate the relationship between sPD-1, sPD-L1, the sPD-1/sPD-L1 ratio, and the rejection activity index.Results:On postoperative day 7, the experimental group exhibited significantly higher peripheral sPD-1 levels (218.59±36.88 vs. 164.95±15.82 ng/L) and a higher sPD-1/sPD-L1 ratio (0.44±0.12 vs. 0.36±0.07), but lower sPD-L1 levels (379.56±73.41 vs. 423.64±96.55 ng/L) compared to the control group (all P<0.05). Correlation analysis revealed a significant positive correlation between sPD-1 levels and the rejection activity index ( r=0.680, P<0.05), as well as between the sPD-1/sPD-L1 ratio and the rejection activity index ( r=0.795, P<0.01), while no correlation was observed between sPD-L1 levels and the rejection activity index. IHC demonstrated positive PD-1 and PD-L1 expression in the liver tissues of the experimental group, whereas the control group showed negative expression. Conclusion:Peripheral blood sPD-1 levels and the sPD-1/sPD-L1 ratio are significantly associated with AR after liver transplantation in rats, suggesting their potential as biomarkers for diagnosing AR in liver transplant recipients.

Objective:To summarize the clinical characteristics, diagnostic and therapeutic approaches, and prognosis of posttransplant lymphoproliferative disease (PTLD) following kidney transplantation.Methods:A retrospective case series analysis was conducted on 7 PTLD patients after kidney transplantation treated in the Department of Transplant Oncology, Tianjin First Central Hospital between January 2018 and December 2023. Clinical features, laboratory findings, imaging and pathological characteristics, treatment modalities, and outcomes were analyzed.Results:Among 7 PTLD patients, there were 5 male and 2 females with a median age of 41 (17-65) years. The median time of onset after operation was 4 (0.5-11) years. Among them, 2 patients had early onset (<1 year post-transplantation) and 5 patients had late onset (>1 year). The clinical manifestations included abdominal mass in 4 cases, anemia in 4 cases, fever in 3 cases, lymphadenopathy in 4 cases, gastrointestinal bleeding in 1 case, abdominal pain in 2 cases, and intestinal obstruction in 2 cases. Pathological types included diffuse large B-cell lymphoma in 4 cases, Burkitt lymphoma in 1 case, marginal zone lymphoma in 1 case, and polymorphic PTLD in 1 case. Reducing the immunosuppressant level was the basal treatment plan, and rituximab, chemotherapy, surgery, radiotherapy and CD19-targeted chimeric antigen receptor therapy were given according to the pathological classification. Until the date of submission, 2 patients had died, 4 had a complete response, and 1 had a partial response. None of the patients had acute rejection, and 1 patient had chronic renal insufficiency.Conclusions:PTLD after kidney transplantation presents with nonspecific manifestations, necessitating prompt imaging and histopathological evaluation for definitive diagnosis. At the same time, a series of measures should be given to improve the prognosis, including discontinuous use of anti-metabolic drugs, dosage decline of calcitric phosphatase inhibitor by 50% or convert it to sirolimus treatment, and corresponding treatment according to the specific conditions of the recipient.

Objective To evaluate the prognostic value of serum tissue factor pathway inhibitor-1(TFPI-1)combined with nuclear factor-κB(NF-κB)in severe traumatic brain injury(STBI).Methods The medical re-cords of 127 patients with STBI admitted to the hospital from July 2022 to August 2024 were retrospectively ana-lyzed and followed up for 6 months.They were divided into poor prognosis group(n=53)and good prognosis group(n=74)according to the prognosis of STBI patients.The serum NF-κB level,clinical data and serum TFPI-1 level of the two groups were compared.The factors affecting the adverse prognosis of STBI patients was screened,and the value of serum NF-κB and serum TFPI-1 in predicting the adverse prognosis of STBI patients were ana-lyzed.Results The serum NF-κB level in the poor prognosis group was higher than good prognosis group,and the serum TFPI-1 level was lower than good prognosis group(P<0.05).The proportion of patients aged>60 years old was higher than good prognosis group(P<0.05).Serum TFPI-1 level(OR=0.328,95%CI:0.156～0.689)was a protective factor for poor prognosis in STBI patients(P<0.05),serum NF-κB level(OR=3.773,95%CI:1.797～7.924)and age>60 years(OR=3.543,95%CI:1.687～7.441)were independent risk factors for poor prognosis in STBI patients(P<0.05).The area under the curve(AUC)of serum TFPI-1 and NF-κB levels and their combined prediction of poor prognosis in STBI patients were 0.784,0.847 and 0.931,respectively(P<0.05),and the AUC value of the combined TFPI-1 and NF-κB levels was higher(P<0.05).Conclusion Serum NF-κB combined with serum TFPI-1 has higher prognostic value in STBI patients.

OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

OBJECTIVE: To identify the key features of facial and tongue images associated with anemia in female populations, establish anemia risk-screening models, and evaluate their performance. METHODS: A total of 533 female participants (anemic and healthy) were recruited from Shuguang Hospital. Facial and tongue images were collected using the TFDA-1 tongue and face diagnosis instrument. Color and texture features from various parts of facial and tongue images were extracted using Face Diagnosis Analysis System (FDAS) and Tongue Diagnosis Analysis System version 2.0 (TDAS v2.0). Least Absolute Shrinkage and Selection Operator (LASSO) regression was used for feature selection. Ten machine learning models and one deep learning model (ResNet50V2 + Conv1D) were developed and evaluated. RESULTS: Anemic women showed lower a-values, higher L- and b-values across all age groups. Texture features analysis showed that women aged 30-39 with anemia had higher angular second moment (ASM)and lower entropy (ENT) values in facial images, while those aged 40-49 had lower contrast (CON), ENT, and MEAN values in tongue images but higher ASM. Anemic women exhibited age-related trends similar to healthy women, with decreasing L-values and increasing a-, b-, and ASM-values. LASSO identified 19 key features from 62. Among classifiers, the Artificial Neural Network (ANN) model achieved the best performance [area under the curve (AUC): 0.849, accuracy: 0.781]. The ResNet50V2 model achieved comparable results [AUC: 0.846, accuracy: 0.818]. CONCLUSION Differences in facial and tongue images suggest that color and texture features can serve as potential TCM phenotype and auxiliary diagnostic indicators for female anemia.

Objective To investigate the impact of osteotomy mode on the callus morphology in the ex-tension area of tibial bone transfer and its efficacy.Methods The information of the patients with bone defect treated in 910 Hospital of Joint Logistics and Security Force of Chinese People's Liberation Army from May 2016 to June 2022 was collected.By comparing the general data of the patients with different osteotomy meth-ods(minimally invasive osteotomy group,subperiosteal osteotomy group and extraperiosteal osteotomy group),callus morphology in the extension area(sunken type,uniform type and protruding type),healing in-dex,Ilizarov Method Research and Application Society(ASAMI)bone healing and functional evaluation and other information,the curative effect differences of different osteotomy methods on tibial bone transfer were investigated.Results The incidence rate of sunken type of callus in the extension area was 15.8%in the mini-mally invasive osteotomy group,18.9%in the subperiosteal osteotomy group,and 14.3%in the extraperioste-al osteotomy group,with statistically significant differences among the three groups(P<0.05);in which,the incidence of sunken type of callus in the minimally invasive osteotomy group was lower than that in the subpe-riosteal osteotomy group(χ2=10.178,P=0.005),but there was no statistically significant difference when compared to the extraperiosteal osteotomy group(χ2=0.102,P=0.814),the difference betrrween the extra-periosteal osteotomy group and subperiosteal osteotomy group also had no statistical difference(χ2=0.084,P=0.772).The incidence rate of uniform type of callus in the minimally invasive osteotomy group was lower than that in the subperiosteal osteotomy group(χ2=6.579,P=0.013),but there was no statistically signifi-cant difference when compared to the extraperiosteal osteotomy group(χ2=0.443,P=0.506).The difference in the subperiosteal osteotomy group and extraperiosteal osteotomy group also had no statistically significant(χ2=2.602,P=0.107).The incidence rate of protruding type of callus in the minimally invasive osteotomy group was higher than that in the subperiosteal osteotomy group(χ2=9.795,P=0.002),and the incidence rate of protruding type of callus in the extraperiosteal osteotomy group was higher than that in the subperios-teal osteotomy group(χ2=5.170,P=0.023),however,there was no statistically significant difference be-tween the minimally invasive osteotomy group and the extraperiosteal osteotomy group(χ2=0.308,P=0.579).There were no statistically significant differences in healing index,ASAMI scores,contact point non-union,pin tract infection and refracture incidence rate rates among the three groups(P>0.05).Conclusion Sub-periosteal osteotomy in the single plane tibial bone moving does not show the expected results in favor of the extension area mineralization,on the contrary,extraperiosteal osteotomy has the similar clinical efficacy to minimally invasive osteotomy.

Objective To explore the feasibility and safety of fastest recovery after surgery(FRAS)in laparoscopic surgery of gastrointestinal tumors.Methods The clinical data of patients undergoing laparoscopic surgery for gastrointestinal tumors under FRAS and enhanced recovery after surgery(ERAS)from Jan.2023 to May 2024 were collected,and perioperative safety and medical cost were analyzed.Results A total of 87 patients were enrolled,including 43 in the FRAS group and 44 in the ERAS group.Compared with the ERAS group,the FRAS group had significantly shorter surgical time(3.0[2.5,3.5]h vs 3.0[2.5,4.0]h),first postoperative movement time([2.85±4.29]h vs[20.18±6.13]h),first postoperative oral feeding time(2.0[2.0,3.0]h vs 24.0[15.0,48.0]h),postoperative hospital stay(24.0[20.0,40.0]h vs 192.0[150.0,216.0]h),lower hospitalization costs(50 515.61[46 650.44,56 827.12]yuan vs 65 555.09[58 683.21,86 239.02]yuan),and lower medication costs(2 671.09[2 063.31,3 127.09]yuan vs 7 326.90[5 104.66,10 674.26]yuan)(all P＜0.05).Conclusion It is safe and feasible to use FRAS during the perioperative period of laparoscopic radical gastrectomy for gastrointestinal tumors,and FRAS can also reduce the costs of hospitalization and medications.

Objective:To analyze the effect of continuous positive airway pressure (CPAP) on maternal and neonatal outcomes in pregnant women with obstructive sleep apnea syndrome (OSAS), especially on the incidence of hypertensive disorder in pregnancy (HDP) in women with moderate to severe OSAS.Methods:A total of 180 pregnant women with OSAS who were diagnosed through sleep monitoring during pregnancy due to high-risk factors of OSAS and registered in Peking University People′s Hospital from January 2021 to May 2024 were selected as the study subjects. Clinical data were collected from medical records for retrospective analysis. According to whether they received standardized treatment with CPAP, they were divided into the CPAP treatment group (42 cases) and the control group (138 cases). The CPAP treatment group consisted of 9 pregnant women with moderate to severe OSAS, while the control group consisted of 34 pregnant women with moderate to severe OSAS. The maternal and neonatal outcomes, the incidence of HDP, placental weight after delivery and placental weight/neonatal birth weight ratio were compared between the two groups.Results:(1) The average gestational age of pregnant women in the CPAP treatment group was higher than that in the control group [(38.7±1.0) vs (38.0±1.4) weeks], the proportion of infants small for gestational age (SGA) in the CPAP treatment group was lower [0 (0/42) vs 12.3% (17/138)], and the birth weight of infants in the CPAP treatment group was bigger [(3 396±475) vs (3 082±710) g); the differences between the two groups were statistically significant (all P<0.05). There were no significant differences between the CPAP treatment group and the control group in terms of delivery mode, rates of postpartum hemorrhage and preterm birth, umbilical artery blood gas analysis pH<7.1, lactate≥6.0 mmol/L, base excess<-12.0 mmol/L and the incidence of gestational diabetes mellitus and HDP (all P>0.05). (2) The placental weight of the CPAP treatment group was significantly lower than that of the control group [(554.0±70.6) vs (615.7±119.1) g], the placental weight/newborn birth weight ratio of the CPAP treatment group was significantly lower than that of the control group (median: 0.17 vs 0.19), and the differences were statistically significant (all P<0.05). (3) The incidence of HDP in pregnant women with moderate to severe OSAS in the CPAP treatment group was lower than that in the control group [1/9 vs 61.8% (21/34)], and the difference was statistically significant ( P<0.05). Conclusions:CPAP treatment could prolong the gestational age in pregnant women with OSAS, reduce the incidence of SGA, increase the birth weight of infants, and reduce the incidence of HDP in pregnant women with moderate to severe OSAS, and is worth promoting in clinical practice. The improvement of neonatal outcomes by CPAP treatment is closely related to the placenta, which is worthy of further exploration.
