OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed, Embase, Web of Science, CNKI, Wanfang data, VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature, extracting data, and evaluating the quality of the literature, descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included, involving 12 models. Nine studies used Logistic regression algorithm for modeling, and the number of included predictive factors ranged from 3 to 11; the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias; 10 studies had high applicability risk. A total of 31 predictive factors were extracted, including 15 items of basic patient information, 3 test indicators, and 5 items of medication information, and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm, with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved, and the overall risk of bias is relatively high.

Objective:To explore the application value of fetal heart ultrasound image segmentation network model based on knowledge distillation technology in the fine segmentation of fetal heart ultrasound image at three-vessel and trachea (3VT) views.Methods:One thousand and three hundred fetals were retrospectively collected from Sir Run Run Shaw Hospital, Zhejiang University College of Medicine from January 2016 to December 2021, the two-dimensional grayscale ultrasound images of fetal heart at 3VT views were analyzed and then divided into training, validation, and test sets. The training and validation sets were used to construct the auxiliary diagnostic network models, and the test set was used to test the reliability of different network models (U-Net, DeepLabv3+ ). The 3VT views were collected and annotated by an experienced doctor as the reference standard. The intersection over union (IoU), pixel accuracy (PA) and Dice coefficient (Dice) were used as the 3 indexes to evaluate the segmentation accuracy, and the diagnostic efficiency of the training model was evaluated. The training model and the most commonly used segmentation models were identified, and the results were compared. A total of 101 images were randomly selected and assigned to junior doctors, AI and junior doctors assisted AI interpretation. Bland-Altman images were drawn to evaluate their consistency with the reference standard, and the results were compared.Results:The training model of knowledge distillation algorithm achieved better results than U-Net, DeepLabv3+ models on all evaluation indexes, and the average IoU, PA and Dice were 68.6%, 81.4% and 81.3%, respectively. Compared with the U-Net model and DeepLabv3+ model, more accurate segmentation boundaries were obtained by the knowledge distillation algorithm training model, and the quantitative evaluation indexes were improved. With the aid of the model, the diagnostic accuracy of junior doctors was improved.Conclusions:The knowledge distillation algorithm training model segmentation method can identify the anatomical structure of the fetal heart in the 3VT view of the fetal heart ultrasound image, and the recognition result is obviously better than other related methods, and can improve the accuracy of image recognition for doctors with low experience.

Objective:To evaluate the role of minimal residual disease (MRD) monitoring during early induction therapy for the treatment of childhood acute lymphoblastic leukemia (ALL).Methods:This was a multicenter retrospective cohort study. Clinical data of 1 164 ALL patients first diagnosed between October 2016 and June 2019 was collected from 16 hospitals in South China Children′s Leukemia Group. According to MRD assay on day 15 of early induction therapy, they were divided into MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group. According to MRD assay on day 33, they were divided into MRD<0.01% group, MRD 0.01%-<1.00% group and MRD≥1.00% group. Age, onset white blood cell count, central nervous system leukemia (CNSL), molecular genetic characteristics and other data were compared between groups. Kaplan-Meier method was used for survival analysis. Cox regression model was used to analyze prognostic factors.Results:Of the 1 164 enrolled patients, there were 692 males and 472 females. The age of diagnosis was 4.7 (0.5, 17.4) years. The white blood cell count at initial diagnosis was 10.7 (0.4, 1 409.0) ×10 9/L. Among all patients, 53 cases (4.6%) had CNSL. The follow-up time was 47.6 (0.5, 68.8) months. The 5-year overall survival (OS) and 5-year relapse-free survival (RFS) rates were (93.1±0.8) % and (90.3±1.1) %. On day 15 of early induction therapy, there were 466 cases in the MRD<0.10% group, 523 cases in the MRD 0.10%-<10.00% group and 175 cases in the MRD≥10.00% group. The 5-year OS rates of the MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group were (95.4±1.0) %, (93.3±1.1) %, (85.4±2.9) %, respectively, while the RFS rates were (93.2±1.6) %, (90.8±1.4) %, (78.9±4.3) %, respectively ( χ2=16.47, 21.06, both P<0.05). On day 33 of early induction therapy, there were 925 cases in the MRD <0.01% group, 164 cases in the MRD 0.01%-<1.00% group and 59 cases in the MRD≥1.00% group. The 5-year RFS rates in the MRD 0.01%-<1.00% group was lowest among three groups ((91.4±1.2) % vs. (84.5±3.2) % vs. (87.9±5.1) %). The difference between three groups is statistically significant ( χ2=9.11, P=0.010). Among ALL patients with MRD≥10.00% on day 15 of induction therapy, there were 80 cases in the MRD <0.01% group on day 33, 45 cases in the MRD 0.01%-<1.00% group on day 33 and 45 cases in the MRD≥1.00% group on day 33. The 5-year RFS rates of three groups were (83.9±6.0)%, (67.1±8.2)%, (83.3±6.9)% respectively ( χ2=6.90, P=0.032). Univariate analysis was performed in the MRD≥10.00% group on day 15 and the MRD 0.01%-<1.00% group on day 33.The 5-year RFS rate of children with CNSL was significantly lower than that without CNSL in the MRD≥10.00% group on day 15 ((50.0±20.4)% vs. (80.3±4.4)%, χ2=4.13, P=0.042). Patients with CNSL or MLL gene rearrangement in the MRD 0.01%-<1.00% group on day 33 had significant lower 5-year RFS rate compared to those without CNSL or MLL gene rearrangement ((50.0±25.0)% vs. (85.5±3.1)%, χ2=4.06, P=0.044;(58.3±18.6)% vs. (85.7±3.2)%, χ2=9.44, P=0.002). Multivariate analysis showed that age ( OR=0.58, 95% CI 0.35-0.97) and white blood cell count at first diagnosis ( OR=0.43, 95% CI 0.27-0.70) were independent risk factors for OS. The MRD level on day 15 ( OR=0.55,95% CI 0.31-0.97), ETV6-RUNX1 fusion gene ( OR=0.13,95% CI 0.03-0.54), MLL gene rearrangement ( OR=2.55,95% CI 1.18-5.53) and white blood cell count at initial diagnosis ( OR=0.52,95% CI 0.33-0.81) were independent prognostic factors for RFS. Conclusions:The higher the level of MRD in early induction therapy, the worse the OS. The MRD levels on day 15 is an independent prognostic factor for RFS.The MRD in early induction therapy guided accurate risk stratification and individualized treatment can improve the survival rate of pediatric ALL.

To analyze the epidemiological characteristics of acute respiratory infections (ARIs) during the autumn-winter season in Beijing, providing evidence for the prevention, control, diagnosis, and treatment of ARIs. A convenience sampling method was employed, enrolling patients who visited Peking Union Medical College Hospital (PUMCH) between September 2023 and February 2024 due to ARIs. Nasopharyngeal swabs were collected, and real-time fluorescence quantitative PCR was used to detect six common respiratory pathogens[influenza A virus (FluA), influenza B virus (FluB), human rhinovirus (HRV), A total of 5556 eligible patients were included. The overall positivity rate for the six common respiratory pathogens was 63.7%, with single-pathogen positivity at 54.0%, dual-pathogen positivity at 8.9%, and triple or more pathogen positivity at 0.7%. The predominant pathogens detected were FluA(16.1%) and RSV(15.7%), followed by ADV(11.1%), MP(11.1%), HRV(10.0%), and FluB(10.0%).No significant difference in overall pathogen positivity was observed between genders.However, significant differences were found between autumn and winter( The prevalence of respiratory pathogens in Beijing is associated with age and season. Targeted preventive measures should be implemented in different seasons and for key populations.

ObjectiveTo investigate the regulatory effect and molecular mechanism of berberine (BBR) on lipophagy in the prevention and treatment of atherosclerotic (AS) lesions in mice. MethodFifty apolipoprotein E-knockout (ApoE-/-) mice were randomly divided into an AS model group, an atorvastatin group (5 mg·kg-1), and low-, medium-, and high-dose BBR groups (2.5, 5, 10 mg·kg-1). Ten C57BL/6J mice were assigned to the control group. After 12 weeks, hematoxylin-eosin (HE) and oil red O staining were performed to assess the histopathological changes of AS plaques in the aorta. Biochemical analysis was used to measure serum lipid levels, and enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), oxidative stress marker reactive oxygen species (ROS), and serum lipophagy marker Beclin1 and microtubule-associated protein 1 light chain 3 Ⅱ (LC3Ⅱ). The xanthine oxidase method was used to measure serum superoxide dismutase (SOD) activity. Immunohistochemistry (IHC) was used to detect the distribution of wingless-type MMTV integration site family member 5a (Wnt5a) and Nieman Pick type C1 (NPC1) in the aorta, and Western blot was used to determine the protein expression of Wnt5a and NPC1 in the aorta. ResultCompared with the control group, the AS model group showed significant AS plaque formation, significantly elevated levels of serum total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), IL-6, TNF-α, and ROS, aortic Wnt5a distribution and protein expression (P<0.01), and significantly reduced levels of serum high-density lipoprotein cholesterol (HDL-C), SOD, Beclin1, LC3Ⅱ, and aortic NPC1 distribution and protein expression (P<0.01). Compared with the AS model group, the atorvastatin group, and high- and medium-dose BBR groups showed a significant reduction in AS plaque area (P<0.05, P<0.01), significantly decreased levels of serum TC, TG, LDL-C, IL-6, TNF-α, ROS, and aortic Wnt5a distribution and protein expression (P<0.05, P<0.01), and significantly increased levels of serum HDL-C, SOD, Beclin1, LC3Ⅱ, and aortic NPC1 distribution and protein expression (P<0.05, P<0.01). There was no statistically significant difference in the above indicators between the atorvastatin group and the medium-dose BBR group. ConclusionBBR can competitively bind to Wnt5a to activate NPC1 expression, upregulate lipophagy levels, reduce blood lipids, and inhibit the release of inflammatory mediators and oxidative stress damage, thereby exerting a preventive and therapeutic effect on AS.
