Objective To evaluate the current radiation doses in pediatric non-cardiac interventional procedures, and analyze the associated clinical factors, and to provide data references for reducing pediatric radiation exposure. Methods We conducted a retrospective analysis of the radiation doses of children who had undergone non-cardiac interventional procedures at the interventional department of a tertiary pediatric hospital in Jinan from January 2022 to October 2024. The collected data included basic demographic information, surgical date, anatomical site, disease type, and radiation dose parameters (cumulative fluoroscopy time, cumulative dose area product in cine mode, cumulative air kerma, and the number of images acquired). The Kruskal-Wallis H test was used for comparative analysis between groups (P < 0.05 was considered statistically significant). Results Among the 475 included children, 99 cases (20.8%) had infantile hemangioma (median P_ka, 0.136 Gy·cm²; median K_a,r, 0.38 mGy), 235 cases (49.5%) had venous malformation (median P_ka, 9.82 Gy·cm²; median K_a,r, 40.99 mGy), 75 cases (15.8%) had lymphatic malformation (median P_ka, 0.06 Gy·cm²; median K_a,r, 0.18 mGy), 32 cases (6.7%) had retinoblastoma (median P_ka, 6.58 Gy·cm²; median K_a,r, 52.34 mGy), 12 cases (2.5%) had arteriovenous malformation (median P_ka, 42.3 Gy·cm²; median K_a,r, 162.87 mGy), and 22 cases (4.6%) had other vascular malformations (median P_ka, 21.7 Gy·cm²; median K_a,r, 89.1 mGy). There were significant differences between children with different disease types in the cumulative fluoroscopy time, cumulative dose area product in cine mode, cumulative air kerma at the patient entrance reference point, and the number of images acquired during non-cardiac interventional procedures (all P < 0.01). Conclusion This study presented the types and proportions of pediatric non-cardiac interventional procedures, evaluated the radiation dose levels of different surgical types, and analyzed the effects of weight and anatomical site on radiation exposure, which can be useful for preliminary assessment of radiation doses in pediatric non-cardiac interventional procedures.

Objective:To investigate and analyze the current situation and influencing factors of the establishment demand for electronic health records (EHR) of residents in Sichuan and Hainan Province under the “Internet+healthcare” ecology.Methods:It was a cross-sectional study. A total of 1 200 residents in Sichuan and Hainan Province were selected with convenient sampling method from June to December 2022. A self-designed questionnaire was conducted through the Questionnaire Star online survey, and the survey mainly included general demographic data and basic establishment demands of electronic health records. A total of 1 200 questionnaires were distributed and 1 200 questionnaires returned with 1 170 valid questionnaires (97.5%), including 409 from Sichuan and 761 from Hainan. Chi-square test was used to compare the differences between the two provinces in the demographic characteristics, basic needs, and binary variables of willingness to application file establishment and physical examination file establishment. Kruskal-Wallis test was used to compare the differences in multiple categorical variables between the two provinces. Binary logistic regression was used to analyze the influencing factors of the establishment needs of the electronic health records.Results:The proportions of residents with bachelor degree or above and those with a family population of less than 3 people in Sichuan were both significantly higher than those in Hainan (55.3% vs 47.4%, 38.4% vs 29.2%); but the proportions of mean monthly income ≤10 000 yuan, annual physical examination, self-health management habits, and having children were all significantly lower than those in Hainan (82.2% vs 87.9%, 67.2% vs 74.4%, 78.5% vs 83.7%, 67.2% vs 73.3%) (all P<0.05). The people who were living in the city, having a mean monthly income >10 000 yuan, receiving annual physical examination, not lived alone, having self-health management habits, knowing the electronic health record, willing to manage the electronic health record by themselves, expecting to manage the health record online, needing special assistance to manage the health record, and willing to pay for additional services were more likely to use the application to establish health records (68.7% vs 56.7%, 82.4% vs 63.0%, 72.2% vs 55.3%, 68.8% vs 62.7%, 69.0% vs 60.4%, 73.2% vs 60.4%, 71.9% vs 36.7%, 71.5% vs 45.7%, 76.6% vs 43.3%, 80.1% vs 44.0%) (all P<0.05). Residents who lived in cities, had annual physical examination, had children, and were willing to manage health records by themselves were more likely to establish physical examination files (46.0% vs 32.5%, 47.9% vs 36.2%, 47.1% vs 33.2%, 45.9% vs 34.4%) (all P<0.05). Willing to manage electronic health records by themselves ( OR=3.803, 95% CI: 2.013-6.875), managing electronic health records online ( OR=1.942, 95% CI: 1.110-3.400), managing electronic health records with dedicated person ( OR=3.277, 95% CI: 2.028-5.294), willing to pay for electronic health records ( OR=3.557, 95% CI: 2.182-5.800), having electronic physical examination records ( OR=1.850, 95% CI: 1.191-2.872) were positively correlated with the willingness to use the application to establish health files, and the age ( OR=0.681, 95% CI: 0.469-0.989) was negatively correlated with the willingness to use the application to establish health files (all P<0.05). Having chronic diseases ( OR=1.389, 95% CI: 1.032-1.868) and willing to manage electronic health records by themselves ( OR=1.553, 95% CI: 1.004-2.401) were positively correlated with willingness to set up health files. Receiving annual physical examination ( OR=0.669, 95% CI: 0.497-0.901), willing to pay for electronic health records ( OR=0.576, 95% CI: 0.423-0.783), willing to use the application to establish health files ( OR=0.715, 95% CI: 0.582-0.979) were negatively correlated with willingness to establish files for physical examination (all P<0.05). Conclusion:Residents in Sichuan and Hainan Province have a high demand for electronic health records, which is affected by many factors. Age and chronic diseases are the significant factors influencing residents′ choices of using apps and physical examinations to establish their health records.

Objective To investigate the effect of day chemotherapy on medical expenses of breast cancer patients.Methods The medical expenses of breast cancer patients in the First Affiliated Hospital of Guangxi Medical Universtiy from January 2019 to September 2023 were retrospectively investigated.Interrupted time series analysis was used to analyze the changes and trend of medical expenses and expenses structure of breast cancer before and after the implementation of day chemotherapy.Results The number of 8066 cases with breast cancer were included in this study.After day chemotherapy,the total expenses and each expense detail decreased significantly(P＜0.001).The total expenses,medicine expense,examination expenses and other expenses showed an upward trend before implementation of day chemotherapy(P＜0.05),the laboratory expenses showed a downward trend before implementation of day chemotherapy(P＜0.001).The total medical expenses decreased by 7306.34 yuan immediately after the implementation of day chemotherapy.The expenses of laboratory test,treatment,examination,nursing,medicine,health materials and other expenses were decreased by 599.59 yuan,1674.34 yuan,1470.66 yuan,91.37 yuan,3473.91 yuan,231.51 yuan and 436.73 yuan,respectively.Conclusion The implementation of day chemotherapy for breast cancer has significantly reduced all kinds of costs,which is conductive to reducing disease burden of patients.

Objective:To explore the efficacy and safety of cryopreservation-free integrated autologous hematopoietic stem cell transplantation (HSCT) model for patients with multiple myeloma.Methods:A total of 96 patients with newly diagnosed multiple myeloma (NDMM) between July 31, 2020, and December 31, 2022, were retrospectively analyzed, of which 41 patients in the observation group received integrated non-cryopreserved transplantation mode. After hematopoietic stem cells were mobilized and collected, melphalan was started immediately for pre-transplant conditioning, and non-cryopreserved grafts from the medical blood transfusion refrigerator were directly injected intravenously into the patient within 24-48 h after the melphalan conditioning. The control group consisted of 55 patients who received traditional transplantation mode. After hematopoietic stem cells were collected, stem cell cryopreservation was performed in liquid nitrogen, and then the transplant plans were started at the right time. All patients received mobilization of autologous hematopoietic stem cells using the G-CSF combined with the plerixafor.Results:① A total of 34 patients (82.9% ) with VGPR plus CR in the observation group were significantly higher than 33 patients (60.0% ) in the control group ( P=0.016). ②Compared with the control group, the incidence of grade 1 oral mucosal inflammation was higher in the observation group ( P<0.001) ; however, the incidence of grades 2 and 3 oral mucosal inflammation was lower ( P=0.004, P=0.048), and neither group experienced grade 4 or above oral mucosal inflammation. The incidence of grade 1 diarrhea was higher in the observation group ( P=0.002), whereas the incidence of grade 3 diarrhea was lower ( P=0.007). No statistically significant difference was observed in the incidence of grade 4 diarrhea ( P=0.506), and neither group experienced grade 5 diarrhea. ③ The incidence of bacterial infection in the observation group was lower than that in the control group (34.1% vs 65.5%, P=0.002), whereas no statistically significant difference was observed in the incidence of fungal infection (29.3% vs 31.4%, P=0.863) and viral infection (4.88% vs 3.64%, P=0.831). ④No statistically significant difference was observed in the implantation time of granulocytes and platelets between the observation and control groups [10 (8-20) days vs 11 (8-17) days, P=0.501; 13 (10-21) days vs 15 (10-20) days, P=0.245]. ⑤ All patients did not receive lenalidomide treatment 100 days post-transplantation. At 30 days post-transplantation, the CTL, NK, and Th cell counts in the observation group were lower than those in the control group ( P<0.001, P=0.002, P=0.049), and the NKT cell counts were higher than those in the control group ( P=0.024). At 100 days post-transplantation, the CTL, NKT, and Th cell counts in the observation group were higher than those in the control group ( P=0.025, P=0.011, P=0.007), and no statistically significant difference in NK cell counts was observed between the two groups ( P=0.396). ⑥ The median follow-up was 18 (4-33) months. The overall 2-year survival rates of the observation and control groups post-transplantation were 91.5% and 78.2%, respectively ( P=0.337). The recurrence-free survival rates were 85.3% and 77.6%, respectively ( P=0.386), and the cumulative recurrence rates were 9.8% and 16.9%, respectively ( P=0.373) . Conclusion:In NDMM, the cryopreservation-free integrated autologous HSCT model can achieve similar therapeutic effects as traditional transplantation models, with lower rates of severe mucosal inflammation and infection compared with traditional transplantation models.

Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a"multi-omics"platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.

Objective:To construct a prognostic nomogram based on epithelial-stromal interaction protein 1(EPSTI1)and predict the pro-gnosis of clear cell renal cell carcinoma(ccRCC).Methods:A retrospective analysis was performed from January 2012 to December 2015 at The First Affiliated Hospital of Fujian Medical University,on 221 patients with ccRCC who underwent surgical treatment in our center and 533 patients with ccRCC in The Cancer Genome Atlas(TCGA)database.Immunohistochemical(IHC)staining was performed on adjacent nor-mal and cancerous tissues to analyze the expression level of EPSTI1 and its correlation with clinicopathological characteristics.Kaplan-Meier survival analysis was performed for the overall survival(OS)and disease-free survival(DFS)of patients with high and low EPSTI1 expression levels.Univariate and multivariate Cox proportional hazards models were used to analyze the prognostic factors for OS,and a nomogram model was constructed and verified.Results:The IHC scores and mRNA expression levels of EPSTI1 were significantly higher in ccRCC tissues than in normal tissues(all P<0.001).EPSTI1 was expressed at higher levels in cancer tissues at higher T stages(P=0.036,P=0.006).The EPSTI1 protein expression level was related to the maximum tumor diameter and TNM stage(P=0.002,P=0.032,respectively).The OS and DFS were higher in the low-EPSTI1-expression group than the high-EPSTI1-expression group(P=0.046,P=0.003,P=0.001).Univariate and multivariate Cox regression analyses showed that a high EPSTI1 protein expression level,WHO/ISUP grade,and AJCC/TNM stage were independent risk factors for poor prognosis(P=0.009,P=0.039,P<0.001).The prognostic nomogram model constructed based on the above variables was su-perior to the AJCC/TNM stage in predicting the 5-year OS,and the calibration curve showed that the predicted value of the model was con-sistent with the actual value.Conclusions:The nomographic model based on EPSTI1,AJCC/TNM staging and WHO/ISUP staging has a strong predictive ability for the prognosis of renal clear cell carcinoma.

Osteoarthritis （OA） is a common degenerative joint disease with a rising incidence rate year by year. Treatment often relies on analgesics and non-steroidal anti-inflammatory drugs （NSAIDs）， which can lead to gastrointestinal damage with long-term use and the recurrence of symptoms. Chinese medicine has a long history of preventing and treating OA， with widespread application and fewer side effects. It offers unique advantages such as a broad treatment scope， multiple targets， and pathways. The effective components of Chinese medicine can reduce the content of reactive oxygen species （ROS）， relieve oxidative stress （OS） damage， and increase the antioxidant capacity of the body by interfering with the expression of biomarkers of OS response such as malondialdehyde （MDA） and superoxide dismutase （SOD）. Through the modulation of signaling pathways such as nuclear factor E₂-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， nuclear factor kappa B （NF-κB）， c-Jun N-terminal kinase （JNK）， NOD-like receptor protein 3 （NLRP3）， and osteoprotegerin （OPG）， they downregulated the expression of inflammatory factors such as interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α）， thereby effectively relieving local joint inflammation， protecting chondrocytes and bone tissue， inhibiting chondrocyte apoptosis， and further alleviating the progression of OA. Currently， there are still certain limitations in the medical research status and development trends of OA， necessitating the continued advancement of traditional Chinese medicine. This paper reviewed the literature on the regulation of OS response by effective components of Chinese medicine for the prevention and treatment of OA， providing new directions and ideas for future research.

Osteoarthritis(OA)mainly lies in the lesions of articular cartilage and surrounding tissues,pro-ducing osteophytes and bone sclerosis,resulting in damage to the articular cartilage.The main pathological mechanism of OA rests with a large number of inflammatory cytokines and inflammatory mediators produced by joint synovial lesions as well as pathological vascular growth at the junction of the synovium and cartilage,which may be one of the key reasons for promoting synovitis and cartilage damage.The OA mainly occurs in the knees,hips,hands and the spine.It is mainly manifested by chronic joint pain,swelling and stiffness,and limitation of motion seriously affects the functional activities of patients.The treatment of OA mainly relies on oral administration or intraarticular injection of drugs to relieve symp-toms.When OA develops to the middle and late stages,the action and life of patients will be seriously affected.There-fore,surgical replacement of joints is considered to ensure the basic life demands of patients.Studies show that traditional Chinese medicine(TCM)treatment has attracted widespread attention and application due to its unique advantages in pre-vention and treatment of OA.Janus kinase(JAK)/signaling transduction and transcriptional activator(STAT)signaling pathway may be one of the important signaling pathways that regulate the chondrocyte proliferation,differentiation and apoptosis.Moreover,it is closely associated with intra-articular inflammatory response.The JAK/STAT signaling pathway regulates the expression of inflammatory factors and related proteins through TCM so as to reduce the inflammatory re-sponse and decrease the chondrocyte damage.It has an important reference value for OA treatment.In this paper,the roles and mechanisms of the TCM monomers and active ingredients and the Chinese herbal compounds in OA by regulating JAK/STAT signaling pathway and affecting related cytokine and protein expression levels have been reviewed,providing a new method and direction for TCM treatment of OA.

Objective To evaluate the effectiveness and safety of indocyanine green fluorescence method versus modified inflation-deflation method for thoracoscopic anatomic segmentectomy. Methods CNKI, Wanfang Database, China Biomedical Literature Database, Web of Science, Cochrane Library, EMbase, PubMed, Clinicaltrials.gov, were searched from 1 January 2000 to 1 May 2023, and controlled studies between indocyanine green fluorescence and modified inflation deflation method in thoracoscopic segmentectomy were collected. Meta-analysis was performed using Stata14MP and RevMan5.4. Results A total of 10 articles, including 1 156 patients, were identified. In thoracoscopic anatomic segmentectomy, indocyanine green fluorescence method had an advantage over modified inflation deflation method. The total incidence of postoperative complications decreased (OR=0.51, 95%CI 0.36 to 0.71, P<0.0001). The incidence of air leaks decreased (OR=0.50, 95%CI 0.31 to 0.80, P=0.004), the operation time shortened (MD=−25.81, 95%CI −29.78 to −21.84, P<0.00001), the length of postoperative hospital stays shortened (MD=−0.98, 95%CI −1.57 to −0.39, P=0.001), the rate of clear displaying for intersegmental boundary line increased (OR=5.79, 95%CI 2.76 to 12.15, P<0.00001). The difference was statistically significant. Conclusion Compared with modified inflation deflation method, indocyanine green fluorescence method can quickly and clearly display the intersegmental boundary line, reduce the difficulty of surgery, shorten the operation time, reduce the length of postoperative hospital stay, and provide reliably technical support for thoracoscopic anatomic segmentectomy. It is an effective and safe method, which is worthy of extensive application.

A 11-year old female patient with severe thalassemia, receipt a lentivirus-based cell and gene therapy (CGT) therapy in Shenzhen Children′s Hosptial on July 27th, 2021. At the two follow-up visits after discharge, patient were continuously tested positive for HIV screening through HIV Ag/Ab Combo assay (chemiluminescence Immunoassay), and the viral load results of HIV-1 nucleic acid testing (NAT) were both>5 000 copies/ml. The patient can be diagnosed with HIV infection according to the National Guideline for Detection of HIV/AIDS(2020 Revised Edition). The thorough investigation findings and supplementary experiment results indicated that the false-positive HIV-1 NAT results was caused by cross-reactivity between the target sites detected by conventional HIV-1 NAT reagents and the lentiviral vectors fragments integrated into the genome of patient′s hematopoietic stem/progenitor cells. In conclusion, it is important for laboratories to select appropriate HIV-1 NAT testing platforms which won′t cause cross-reactivity for the testing of samples from patients who have been treated with HIV-derived vectors. It is also recommended to design and develop NAT testing platforms with multiple target regions labeled by different fluorescents for HIV NAT supplementation experiment to reduce the risk of false-positive diagnoses of HIV infection.
