Objective To investigate the probability and dosimetric risk factors of lung injury after sequential immune checkpoint inhibitors (ICIs) and thoracic radiotherapy. Methods A retrospective analysis was conducted on 139 patients who received sequential ICIs and thoracic radiotherapy in Xuzhou Cancer Hospital and Affiliated Hospital of Xuzhou Medical University between February 2020 and February 2024. The relationships of clinical factors and lung and heart volume dose parameters with grade ≥ 2 acute lung injury (ALI) in patients with thoracic tumors were studied using univariable (χ² test, t test, nonparametric test) and multivariable (binary logistic regression analysis) methods. The thresholds of dosimetric risk factors were determined using the receiver operating characteristic curves. Clinical factors included age, gender, smoking history, type of ICIs, cycle of ICI application, and the interval between ICI application and thoracic radiotherapy. Dose parameters included total radiotherapy dose, single dose, planning target volume, maximum dose of planning target volume, average dose of planning target volume, total lung volume, heart volume, and the V₅, V₁₀, V₁₅, V₂₀, V₂₅, V₃₀, V₃₅, and V₄₀ of lung and heart. Results The incidence of grade ≥ 2 ALI in the included cases was 36% (50/139). The χ² test did not find any statistically significant clinical factors. In the univariable and binary Logistic regression analysis, lung V₁₅ and V₂₀, heart V₁₅ and V₂₀, and lung volume were independent risk factors for the occurrence of grade ≥ 2 ALI in sequential ICIs and thoracic radiotherapy. The thresholds were 18.51% for lung V₁₅, 14.43% for lung V₂₀, 32.41% for heart V₁₅, and 17.74% for heart V₂₀. Conclusion For patients who are going to receive thoracic radiotherapy after ICIs, the thresholds of lung V₁₅ and V₂₀ and heart V₁₅ and V₂₀ in the radiotherapy plan are recommended to be less than 18.51%, 14.43%, 32.41%, and 17.74%, respectively, which can effectively reduce the occurrence of grade ≥ 2 ALI.

In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024.

OBJECTIVE: To observe the therapeutic effect of electroacupuncture (EA) in improving early enteral nutrition tolerance in patients with acute pancreatitis (AP) under the concept of accelerated rehabilitation, and to explore the related mechanism based on the changes in autonomic nerve characteristics. METHODS: A total of 42 patients with AP were randomized into an observation group (21 cases, 1 case dropped out) and a control group (21 cases, 1 case dropped out). The control group received standard basic treatment for AP. On the basis of the treatment in the control group, EA was applied in the observation group, bilateral Zusanli (ST36), Yixian point (Extra), Tianshu (ST25), Neiguan (PC6) and Zhongwan (CV12) were selected as the main points, and the supplementary points were selected according to syndrome differentiation. Ipsilateral Zusanli (ST36) and Yixian point (Extra) were connected to EA, using discontinuous wave, in frequency of 2 Hz, 30 min a time, once a day for 6 continuous days. The enteral nutrition tolerance score was observed before treatment and after 3 and 5 days of treatment; the visual analogue scale (VAS) score for abdominal pain was observed before treatment and after 3 days of treatment; the time of reaching the feeding goal and hospital stay was recorded; the levels of C-reactive protein (CRP) and amylase were measured before treatment and after 5 days of treatment; the heart rate variability (HRV) indexes (standard deviation of NN intervals [SDNN], average standard deviation of NN intervals [SDANN], root mean square of successive NN interval differences [rMSSD], low frequency [LF] and high frequency [HF], ratio of low frequency to high frequency [LF/HF]) were monitored in the two groups. RESULTS: After 3 and 5 days of treatment, the enteral nutrition tolerance scores were decreased compared with those before treatment in both groups (P<0.01), the reductions in the observation group were larger than those in the control group (P<0.01). After 3 days of treatment, the VAS scores for abdominal pain were decreased compared with those before treatment in both groups (P<0.01), the reduction in the observation group was larger than that in the control group (P<0.01). The time of reaching the feeding goal and hospital stay in the observation group was shorter than that in the control group (P<0.05). After 5 days of treatment, the CRP and amylase levels were decreased compared with those before treatment in both groups (P<0.01), the reduction of CRP level in the observation group was larger than that in the control group (P<0.01). In the observation group, SDNN, SDANN and LF/HF were lower than those in the control group (P<0.05, P<0.01), while rMSSD was higher than that in the control group (P<0.01). SDNN, SDANN and LF/HF were positively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.05), while rMSSD was negatively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.01). CONCLUSION Electroacupuncture can improve enteral nutrition tolerance in patients with AP by regulating autonomic nervous function, alleviating the inflammation, promoting accelerated recovery, and reducing the length of hospital stay.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

OBJECTIVE: To determine the prevalence of lumbar spondylolysis (LS) and the proportion of spondylolytic spondylolisthesis (SS) in China, and to evaluate the musculoskeletal status of patients with LS and SS. METHODS: Spine Computed Tomography (CT) images were collected from community populations aged 40 and above in a nationwide multi-center project. LS was diagnosed, and SS was graded by an experienced radiologist. Bone mineral density (BMD) and paraspinal muscle parameters were quantified based on CT images. RESULTS: One hundred and seventeen patients of a total of 3,317 individuals were diagnosed with LS, corresponding to a prevalence rate of 3.53%. 63 of the 1,214 males (5.18%) and 54 of the 2,103 females (2.57%) were diagnosed with LS. SS occurred in 64/121 vertebrae (52.89%). BMD was not associated with LS ( P = 0.341). The L5 extensor paraspinal muscle density was higher in the LS group than in the non-LS group. In the LS group, patients with SS had a smaller L5 paraspinal extensor muscle cross-sectional area than those without SS ( P = 0.003). CONCLUSION The prevalence of LS in Chinese adults was 3.53%, with prevalence rates of 5.18% in males and 2.57% in females. Patients with LS have higher muscle density, whereas those with SS have smaller muscle cross-sectional areas at the L5 level.

OBJECTIVES: To propose a hypothesis that aloe-emodin may inhibit scar tissue fibrosis through thrombospondin-1(THBS1)-PI3K-Akt pathway. METHODS: By cultivating fibroblasts derived from scar tissue after cleft palate surgery in humans, aloe emodin of different concentrations (10, 20, 30, 40 and 50 μmol/L) was added to the cells which activity was detected. At the same time, transcriptome sequencing was performed on scar tissue and cells, and bioinformatics methods were used to explore potential targets and signaling pathways of scar tissue fibrosis. RESULTS: Aloe-emodin had a concentration dependent inhibitory effect on fibroblast proliferation,with the 40 μmol/L concentration group showing the most significant effect. The results of tissue and cell sequencing indicated that differentially expressed genes were significantly enriched in extracellular matrix-receptor interaction pathway, and shared a common differential gene which was THBS1. The ORA analysis results indicated that differentially expressed genes, including THBS1, were significantly enriched in the PI3K-Akt signaling pathway. CONCLUSIONS Aloe emodin may inhibit the PI3K-Akt pathway by downregulating THBS1, thereby reducing the proliferation activity of fibroblasts derived from postoperative palatal scar tissue.

Objective To establish an intelligent detection algorithm model for acute promyelocytic leukemia(M3 model)based on a contrast large model using machine learning statistical software and validate its effectiveness.Methods The data from 8 256 outpa-tients and inpatients who underwent complete blood cell analysis at Peking Union Medical College Hospital were retrieved and analyzed using the laboratory information system(LIS)and hospital information system(HIS).A M3 screening model was established and vali-dated using the data from outpatients and inpatients who underwent complete blood cell analysis at our hospital from July to October 2023.Results The M3 model demonstrated potential application value in screening for M3 disease in complete blood cell analysis,which showed certain efficacy in screening for neutrophil toxicity changes,particularly in identifying two cases of blue-green inclusion bodies in neutrophils.Conclusion The M3 model exhibited low specificity for M3 diagnosis.Future research should focus on increas-ing the number of M3-positive cases to optimize the model,ensuring high sensitivity while improving specificity.This model will provide assistance for the intelligent review of complete blood cell analysis.

Objective:To explore the prognostic factors of primary plasma cell leukemia (pPCL) in the era of novel agents.Methods:The clinical data of 66 patients with pPCL treated at the Department of Haematology, Beijing Chao-Yang Hospital, Capital Medical University from 2011 to 2022 were retrospectively collected to analyze their prognostic factors.Results:Among the 66 patients with pPCL, the median age was 59 (range: 29-79) years. The median overall survival (OS) duration was 19.0 (95% CI 10.4-27.6) months, and the median progression-free survival (PFS) duration was 11.0 (95% CI 6.5-15.6) months. The median OS and PFS were significantly longer in patients with the best post-treatment response of very good partial remission (VGPR) or better than in patients with a response of partial remission (PR) or worse (median OS: 33.0 months vs 6.0 months, P<0.001; median PFS: 16.0 months vs 3.0 months, P<0.001). OS was significantly longer in patients who underwent autologous hematopoietic stem cell transplantation than in those who did not undergo transplantation (49.0 months vs 6.0 months, P=0.002), and there was a trend toward a longer PFS in patients who underwent transplantation than in those who did not undergo transplantation (19.0 months vs 8.0 months, P=0.299). The median OS and PFS were significantly longer in patients who received maintenance therapy than in those who did not receive maintenance therapy (median OS: 56.0 months vs 4.0 months, P<0.001; median PFS: 20.0 months vs 2.0 months, P<0.001). Multivariate analysis showed that hypercalcemia was an independent risk factor ( HR=3.204, 95% CI 1.068-9.610, P=0.038) for patients with pPCL, while receiving maintenance therapy ( HR=0.075, 95% CI 0.022-0.253, P<0.001) and post-treatment response of VGPR or better ( HR=0.175, 95% CI 0.048-0.638, P=0.008) were independent protective factors for patients with pPCL. Conclusions:In the era of novel agents, hypercalcemia, receiving maintenance therapy, and post-treatment response of VGPR or better are independent prognostic factors for pPCL.

Objective To investigate the effect and mechanism of transplantation of neuregulin1(NRG1)gene-modified bone marrow mesenchymal stem cells(BMSCs)on the repair of hemi-transected spinal cord injury(SCI)in rats.Methods Isolated and cultured rat BMSCs,followed by transfection with the NRG1 gene.The levels of NRG1 in BMSCs lysate and culture supernatant was deected by ELISA method,and the proliferation activity of the BMSCs was detected by cell counting method.Forty-three healthy 8-week-old SD rats were randomly divided into control group(n=10),SCI model group(n=10),BMSCs group(n=10),and NRG1-BMSCs group(n=13).After establishing the spinal cord hemisection model,animals received in-situ transplantation of BMSCs or NRG1-BMSCs.On the 1,7,14,21,and 28 days after transplantation,the hind limb motor function was evaluated using BBB score and inclined plate test;on the 7th day after transplantation,the migration and distribution of transplanted cells was monitored using a fluorescence microscope;on the 28th day after transplantation,the pathological changes of rat spinal cord tissues was examined using HE staining and Nissl staining;cell apoptosis using TUNEL staining,and levels of endoplasmic reticulum stress-related proteins[X-box binding protein 1(XBP1),C/EBP homologous protein(CHOP),activating transcription factor 4(ATF4),ATF6,glucose-regulated protein 78(GRP78)]and apoptosis-related proteins[B-cell lymphoma-2(Bcl-2)and Bcl-2-associated protein X(Bax)]in rat spinal cord tissues using Western blotting.Results BMSCs were successfully isolated,cultured,and transfected with the NRG1 gene.ELISA method results showed that the NRG1 contents in the NRG1-BMSCs lysate and culture supernatant were significantly higher than that of BMSCs in a time-dependent manner(P<0.05).The proliferation activity of NRG1-BMSCs was significantly higher than that of BMSCs(P<0.05).On the 21 and 28 days after transplantation,the BBB score and the slope angle of the inclined plate in NRG1-BMSCs group were higher than those in SCI model group or BMSCs group(P<0.05).However,it did not reverse to the level in control group(P<0.05).On the 28th day after transplantation,compared with the SCI model group and BMSCs group,neuronal pyknosis reduced,the Nissl body density increased,the expression levels of XBP1,CHOP,ATF4,ATF6,GRP78,and Bax,and the rate of TUNEL-positive cells significantly reduced in NRG1-BMSCs group(P<0.05),and the expression level of Bcl-2 significantly increased(P<0.05).Conclusion Transplantation of NRG1 gene-modified BMSCs can alleviate SCI and improve the recovery of motor function in rats.The mechanism may be related to promoting the proliferation activity of BMSCs,inhibiting cell apoptosis,and mitigating endoplasmic reticulum stress.
