Objective To explore the efficacy of hypofractionated radiotherapy at different time intervals after surgery for keloid,and to analyze the factors affecting the efficacy.Methods A total of 76 patients who underwent 20 Gy/5 postoperative radiotherapy regimen in the Fifth Affiliated Hospital of Zhengzhou University from January 2021 to June 2023 were selected as study subjects,and a total of 100 keloids were divided into effective group(n=79)and recurrence group(n=21).Regular follow-up and record of the patients after radiotherapy treatment effect and adverse effects,and multivariate Logistic was used to analyze factors of recurrence in keloid patients.Results Multivariate Logistic regression analysis found that postoperative radiotherapy time and scar incision length were related to recurrence after treatment,radiotherapy within 7h of surgery was an independent risk factor for recurrence after treatment(OR＞1,P=0.022),and scar incision≤5cm was an independent protective factor for recurrence after treatment(OR＜1,P=0.028).Conclusion Surgical excision combined with hypofractionated radiotherapy is one of the effective measures to prevent and treat keloid recurrence,though keloids on the trunk may need more effective treatment options.The recurrence rate of radiotherapy initiated 7-48h after surgery is relatively the lowest,and it is worthy of clinical promotion and application.

Microglial pyroptosis and neuroinflammation have been implicated in the pathogenesis of sepsis-associated encephalopathy (SAE). OGT-mediated O-GlcNAcylation is involved in neurodevelopment and injury. However, its regulatory function in microglial pyroptosis and involvement in SAE remains unclear. In this study, we demonstrated that OGT deficiency augmented microglial pyroptosis and exacerbated secondary neuronal injury. Furthermore, OGT inhibition impaired cognitive function in healthy mice and accelerated the progression in SAE mice. Mechanistically, OGT-mediated O-GlcNAcylation of ATF2 at Ser44 inhibited its phosphorylation and nuclear translocation, thereby amplifying NLRP3 inflammasome activation and promoting inflammatory cytokine production in microglia in response to LPS/Nigericin stimulation. In conclusion, this study uncovers the critical role of OGT-mediated O-GlcNAcylation in modulating microglial activity through the regulation of ATF2 and thus protects against SAE progression.

ObjectiveTo evaluate the quality of Lygodium japonicum (Thunb.) Sw. (L. japonicum, Hai Jin Sha) by comparing its components without stewed (W) and stewed (S) using ultra-high-performance liquid chromatography (UHPLC) and chemometric analysis. Additionally, network pharmacology was employed to investigate the possible mechanisms of action of L. japonicum in the urinary calculi (UC) treatment.MethodsA fingerprinting method was established to identify components through UHPLC-tandem mass spectrometry. Chemometric techniques were used to compare the L. japonicum extraction methods. Furthermore, various network pharmacological approaches were used to identify and analyze the potential targets of the identified components in relation to UC.ResultsThe W and S extracts were distributed into two distinct clusters. Significant differences in the levels of protocatechuic aldehyde, caffeic acid, and p-coumaric acid were observed between S and W. Network pharmacology analysis revealed that the primary targets of L. japonicum in the UC treatment were serum albumin and epidermal growth factor receptors, with potential active components including protocatechuic acid and caffeic acid.ConclusionThis study comprehensively examined the therapeutic components of L. japonicum before and after boiling, shedding light on its potential mechanisms of action in UC treatment. These findings offer valuable insights into the development and utilization of L. japonicum resources.

Objective: To understand the influence of the concept of movement education on the fundamental motor skills of preschool children aged 3-6, so as to provide a reference for improving the quality of preschool education and promoting the all round development of preschool children. Methods: From August 2022 to June 2023, 592 normally developing preschool children aged 3- 6 in a certain kindergarten in Qingdao were selected as the research objects by convenience sampling. They were randomly divided into the intervention group (physical education activities designed based on the concept of movement education) and the control group (original teaching plan). The intervention lasted for 24 weeks (twice a week, 40 minutes each time). Test of Gross Motor Development-2 (TGMD-2) was used to evaluate the children s gross motor skills, and repeated measures analysis of variance was used to analyze the data of the two groups before and after the intervention. Results: Except for running and kicking, the group main effects ( F group =18.78-104.77), time main effects( F time =243.23-3 003.19), and other interactive effects between group and time ( F group×time =14.01-322.91) were of statistical significances for gross motor, movement motor, manipulative motor and each sub indicator between intervention group and control group. Further simple effect analysis results showed that, before intervention, there were no statistically significant differences in the total scores of gross motor (48.95±10.65,45.87±10.98), movement motor ( 25.93± 7.31,23.46±7.32) and manipulative motor (23.15±4.40,22.40±4.69) between the intervention group and the control group ( F=3.69, 2.94, 1.90, P >0.05); and two goups were also found of no statistical significance in the each sub indicator of movement and manipulative motor ( F=0.01-3.58, P >0.05); after intervention, the total scores of gross motor, movement motor, and manipulative motor in the intervention group (75.92±9.48, 38.12±5.40, 37.80±4.92) were all better than those in the control group ( 59.52± 12.12, 30.71±7.47, 28.81±5.54) ( F =168.15, 97.58, 210.71), and the total indicators of both goups had better scores than those before the intervention ( F intervention = 3 498.90 , 1 438.27, 2 431.24; F control =545.58, 309.18, 283.29)(all P <0.01); after intervention, the intervention group had better scores in all sub indicators (except for running and kicking) than the control group ( F =43.57-297.71), and the each sub indicator of both goups had better scores than those before the intervention ( F intervention = 300.58-858.65; F control =12.28-135.64)(all P <0.01). Conclusion Physical education activities designed based on the concept of movement education could better promote the development of children s fundamental motor skills.

Objective:To analyze the clinical characteristics of dengue fever patients, summarize the course and characteristics of the disease, and analyze the risk factors that affect the condition.Methods:Retrospective collection of general information, clinical symptoms, medical history, laboratory tests, prognosis and other clinical data of dengue fever patients that admitted to Jinghong First People's Hospital and severe dengue fever patients at People's Hospital of Xishuangbanna Dai Autonomous Prefecture from June to December 2023 was conducted using a case report form (CRF). According to the diagnostic criteria of the World Health Organization (WHO), patients were divided into dengue fever group, dengue fever with warning signs group, and severe dengue fever group. The differences in clinical data between different groups of patients were analyzed and compared. Binary multiple factor Logistic regression analysis was used to explore the risk factors affecting the severity of dengue fever in patients. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of prediction models constructed for various risk factors for severe dengue fever. Subgroup analysis was performed on the prognosis of severe dengue fever patients, and the differences in clinical data between two groups of patients with different prognoses were compared. Binary multivariate Logistic regression analysis was used to explore the risk factors affecting the prognosis of severe dengue fever patients. ROC curve was drawn to analyze the predictive value of prediction models constructed for various risk factors on the prognosis of severe dengue fever patients.Results:A total of 2 264 patients were included, including 499 cases in the dengue fever group, 1 379 cases in the dengue fever with warning signs group, and 386 in the severe dengue fever group (43 deaths and 343 survivors). The most common symptom of dengue fever patients was fever (94.70%), followed by muscle soreness (70.54%), headache (63.12%), fatigue (58.92%), and chills (46.02%). Compared with the dengue fever group and the dengue fever with warning signs group, the ratio of thalassemia and the levels of cardiac troponin (cTnI, cTnT), MB isoenzyme of creatine kinase (CK-MB), and myoglobin were significantly increased in patients with severe dengue fever group, albumin (Alb) was significantly decreased in patients with severe dengue fever group. The levels of cTnT and myoglobin in patients with dengue fever with warning signs group were significantly higher than those in the dengue fever group, and the level of Alb in patients with dengue fever with warning signs group was significantly lower than that in the dengue fever group, the differences were statistically significant (all P < 0.05). Binary multivariate Logistic regression analysis showed that thalassemia [odds ratio ( OR) = 6.214, 95% confidence interval (95% CI) was 2.337-16.524, P < 0.001], Alb ≤ 36 g/L ( OR = 6.297, 95% CI was 4.270-9.286, P < 0.001), and cTnT levels ( OR = 1.008, 95% CI was 1.002-1.015, P = 0.016) were risk factors for severe dengue fever. ROC curve analysis showed that the area under the ROC curve (AUC) for predicting severe dengue fever based on the prediction models constructed for the above risk factors was 0.856, with the best predictive value of 0.067, sensitivity of 67.1%, and specificity of 99.4%. In the subgroup analysis of patients with severe dengue fever, compared with the survival group, the levels of hematocrit (HCT), cTnT, and CK-MB in the death group patients were significantly increased, while the level of Alb was significantly decreased, and the differences were statistically significant. Binary multivariate Logistic regression analysis showed that Alb ( OR = 0.839, 95% CI was 0.755-0.932, P = 0.001), HCT ( OR = 1.086, 95% CI was 1.010-1.168, P = 0.025), elevated troponin level ( OR = 10.119, 95% CI was 2.596-39.440, P < 0.001), and CK-MB ( OR = 1.081, 95% CI was 1.032-1.133, P < 0.001) were risk factors for mortality in patients with severe dengue fever. ROC curve analysis showed that the AUC for predicting death in severe dengue fever patients based on the prediction models constructed for the above risk factors was 0.881, with the best predictive value of 0.113, sensitivity of 75.0%, and specificity of 88.9%. Conclusion:Thalassemia, Alb≤36 g/L, and cTnT level are risk factors for severe dengue fever, while HCT level, Alb level, CK-MB level, and elevated troponin level are risk factors for death in patients with severe dengue fever.
