With the widespread application of deep learning technology in radiotherapy, increasing attention has been directed toward enhancing the precision and personalization of intelligent radiotherapy for osteosarcoma. This review summarizes the recent advances in the application of deep learning to osteosarcoma image preprocessing, automatic target volume delineation, dose prediction and treatment plan optimization, early efficacy assessment, and follow-up monitoring. Bottlenecks such as data sharing, model generalization, and interpretability are analyzed. This review aims to provide a comprehensive reference for technological iteration and clinical implementation in this field, as well as a scientific basis for the determination of future research directions and the development of standardized guidelines.

Objective To explore the relationship between the severity of white matter hyperintensities(WMH)and the distribution of collateral disease syndrome types.Methods A total of 208 patients clearly diagnosed with cerebral small vessel disease in Lishui TCM Hospital Affiliated to Zhejiang Chinese Medical University from December 2022 to December 2023 were selected as the study subjects.All enrolled subjects in the study completed the collateral disease syndrome differentiation.WMH was graded on magnetic resonance imaging fluid-attenuated inversion recovery(FLAIR)sequences using the Fazekas scale and measured for volume.Results Among the 208 patients,there were 52 cases of the brain collateral impoverishment(BCI)type,with Fazekas score of 3(2,3)points,and WMH volume of(8.80±9.37)ml;67 cases of the brain collateral stasis(BCS)type,with Fazekas score of 4(3,4)points,and WMH volume of(13.42±9.18)ml;47 cases of the brain collateral constraint(BCC)type,with Fazekas score of 4(3,5)points,and WMH volume of(14.60±10.07)ml;and 42 cases of the brain collateral occlusion(BCO)type,with Fazekas score of 4(4,5)points,and WMH volume of(18.65±10.71)ml.Of these,55 patients with a Fazekas score of 1-2 points were most commonly of the BCI type,105 patients with a Fazekas score of 3-4 points were most commonly of the BCS type,and 48 patients with a Fazekas score of 5-6 points were most commonly of the BCO type.There were statistically significant differences in Fazekas scores and WMH volumes between the BCI and BCO types and other syndrome types(P<0.05).Conclusion The severity of WMH corresponds to a certain distribution of collateral disease syndrome types,and can serve as a reference indicator for assessing the severity of illness in patients with collateral disease.

Objective:To analyze the iodine nutrition status of pregnant women in Weihai City before and after (2022, 2023) the iodine deficiency disorders (IDD) intervention, evaluate the effectiveness of intervention measures, and provide a scientific basis for adjusting IDD prevention strategies in the city.Methods:In May 2023, the intervention action of IDD was carried out for pregnent women in Weihai City. In April 2022 and December 2023, respectively, a cross-sectional survey method was conducted in four districts (cities) of Weihai City. Each district (city) was divided into five areas (east, west, south, north, and central) each year, and one township (street) was selected from each areas. At least 20 pregnant women were selected from each township (street) as survey subjects, and their household salt samples and random urine samples were collected to measure salt iodine and urinary iodine concentrations, and to compare the test results.Results:A total of 922 household salt samples were tested, including 530 iodized salt samples and 469 qualified iodized salt samples. The median salt iodine was 24.00 mg/kg. The coverage rate of iodized salt, the qualified rate of iodized salt, and the consumption rate of qualified iodized salt were 57.48%, 88.49%, and 50.87%, respectively. No significant difference was observed in medians salt iodine between 2022 (24.26 mg/kg) and 2023 (24.00 mg/kg, Z = - 1.58, P = 0.113). However, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in 2023 werehigher than those in 2022 [73.72% (373/506) vs 37.74% (157/416), 65.22% (330/506) vs 33.41% (139/416), χ 2 = 120.90, 92.40, P < 0.001]. A total of 922 urine samples were collected from pregnant women, with a median urinary iodine of 135.90 μg/L. The median urinary iodine of pregnant women in 2022 was 113.55 μg/L. There was a statistically significant difference in medians urinary iodine among different regions ( H = 27.91, P < 0.001). The median urinary iodine of pregnant women in 2023 was 153.00 μg/L. There was no statistically significant difference in medians urinary iodine among different regions ( H = 3.33, P = 0.343). The medians urinary iodine of pregnant women in Huancui District, Wendeng District, and Rushan City in 2023 (156.60, 155.00, 140.85 μg/L) were higher than those in 2022 (93.60, 110.00, 110.70 μg/L), and the differences were statistically significant ( Z = - 5.44, - 4.92, - 5.99, P < 0.001). The median urinary iodine of pregnant women in Weihai City in 2023 showed a statistically significant difference compared to 2022 ( Z = - 7.62, P < 0.001). Conclusions:The IDD intervention measures in Weihai City have achieved good results, and the coverage of iodized salt, the consumption rate of qualified iodized salt, and the iodine nutrition level of pregnant women have improved. We should continue to implement intervention measures, improve the iodine nutrition level of key populations, and maintain a sustained elimination of IDD.

Background and Aims:Laparoscopic pancreaticoduodenectomy(LPD)has become a preferred approach for periampullary tumors,yet delayed gastric emptying(DGE)remains a frequent complication that hampers postoperative recovery.The nasojejunal feeding tube(NJT)is commonly used for early enteral nutrition,but its impact on DGE is controversial.This study aimed to evaluate whether intraoperative NJT placement increases the risk of DGE after LPD and to assess its influence on postoperative recovery outcomes.Methods:A retrospective cohort of 319 patients who underwent LPD at Provincial Hospital Affiliated to Shandong First Medical University from April 2017 to November 2023 was analyzed.Patients were divided into two groups based on intraoperative NJT placement(NJT group,n=200;non-NJT group,n=119).The incidence of DGE and postoperative outcomes were compared.Multivariate logistic regression and propensity score matching(PSM)were performed to identify independent risk factors for DGE.Results:The incidence of grade B/C DGE was significantly higher in the NJT group than in the non-NJT group(36.5%vs.21.8%,P=0.006).NJT placement was associated with longer postoperative hospital stay and higher hospitalization costs(both P<0.05).Multivariate analysis revealed intraoperative NJT placement(OR=1.960,95%CI=1.142-3.363,P=0.015)and intraoperative blood loss>400 mL(OR=1.921,95%CI=1.155-3.194,P=0.012)as independent risk factors for DGE.These findings were consistent after PSM.Conclusions:Prophylactic intraoperative NJT placement confers no additional benefit for postoperative recovery after LPD and is associated with a higher risk of DGE,prolonged hospitalization,and increased medical costs.Routine NJT placement should therefore be avoided,and individualized strategies should be adopted to minimize postoperative complications and enhance recovery.
