Objective:To investigate the value of an MRI and digital pathology images based omics nomogram for the prediction of recurrence risk in soft tissue sarcoma (STS).Methods:This was a retrospective cohort study. From January 2016 to March 2021, 192 patients with STS confirmed by pathology in the Affiliated Hospital of Qingdao University were enrolled, among which 112 patients in the Laoshan campus were enrolled as training set, and 80 patients in the Shinan campus were enrolled as validation set. The patients were divided into recurrence group ( n=87) and no recurrence group ( n=105) during follow-up. The clinical and MRI features of patients were collected. The radiomics features based on fat saturated T 2WI images and pathomics features based on digital pathology images of the lesions were extracted respectively. The clinical model, radiomics model, pathomics model, radiomics-pathomics combined model, and omics nomogram which combined the optimal prediction model and the clinical model were established by multivariate Cox regression analysis. The concordance index (C index) and time-dependent area under the receiver operating characteristic curve (t-AUC) were used to evaluate the performance of each model in predicting STS postoperative recurrence. The DeLong test was used for comparison of t-AUC between every two models. The X-tile software was used to determine the cut-off value of the omics nomogram, then the patients were divided into low risk ( n=106), medium risk ( n=64), and high risk ( n=22) groups. Three groups′ cumulative recurrence-free survival (RFS) rates were calculated and compared by the Kaplan-Meier survival curve and log-rank test. Results:The performance of the radiomics-pathomics combined model was superior to the radiomics model and pathomics model, with C index of 0.727 (95% CI 0.632-0.823) and medium t-AUC value of 0.737 (95% CI0.584-0.891) in the validation set. The omics nomogram was established by combining the clinical model and the radiomics-pathomics combined model, with C index of 0.763 (95% CI 0.685-0.842) and medium t-AUC value of 0.783 (95% CI0.639-0.927) in the validation set. The t-AUC value of omics nomogram was significantly higher than that of clinical model, TNM model, radiomics model, and pathomics model in the validation set ( Z=3.33, 2.18, 2.08, 2.72, P=0.001, 0.029, 0.037, 0.007). There was no statistical difference in t-AUC between the omics nomogram and radiomics-pathomics combined model ( Z=0.70, P=0.487). In the validation set, the 1-year RFS rates of STS patients in the low, medium, and high recurrence risk groups were 92.0% (95% CI 81.5%-100%), 55.9% (95% CI 40.8%-76.6%), and 37.5% (95% CI 15.3%-91.7%). In the training and validation sets, there were statistically significant in cumulative RFS rates among the low, medium, and high groups of STS patients (training set χ2=73.90, P<0.001; validation set χ2=18.70, P<0.001). Conclusion:The omics nomogram based on MRI and digital pathology images has favorable performance for the prediction of STS recurrence risk.

Background::Cerebrovascular disease (CVD) ranks among the foremost factors responsible for mortality on a global scale. The mortality patterns of CVDs and temporal trends in China need to be well-illustrated and updated.Methods::We collected mortality data on patients with CVD from Chinese Center for Disease Control and Prevention’s Disease Surveillance Points (CDC-DSP) system. The mortality of CVD in 2020 was described by age, sex, residence, and region. The temporal trend from 2013 to 2019 was evaluated using joinpoint regression, and estimated rates of decline were extrapolated until 2030 using time series models.Results::In 2019, the age-standardized mortality in China (ASMRC) per 100,000 individuals was 113.2. The ASMRC for males (137.7/10 5) and rural areas (123.0/10 5) were both higher when stratified by gender and urban/rural residence. The central region had the highest mortality (126.5/10 5), the western region had a slightly lower mortality (123.5/10 5), and the eastern region had the lowest mortality (97.3/10 5). The age-specific mortality showed an accelerated upward trend from aged 55-59 years, with maximum mortality observed in individuals over 85 years of age. The age-standardized mortality of CVD decreased by 2.43% (95% confidence interval, 1.02-3.81%) annually from 2013 to 2019. Notably, the age-specific mortality of CVD increased from 2013 to 2019 for the age group of over 85 years. In 2020, both the absolute number of CVD cases and the crude mortality of CVD have increased compared to their values in 2019. The estimated total deaths due to CVD were estimated to reach 2.3 million in 2025 and 2.4 million in 2030. Conclusion::The heightened focus on the burden of CVD among males, rural areas, the central and western of China, and individuals aged 75 years and above has emerged as a pivotal determinant in further decreasing mortalities, consequently presenting novel challenges to strategies for disease prevention and control.

Objective:To analyze the epidemiological distribution characteristics, influencing factors, and infection rates of pertussis in the population of Henan Province.Methods:From 2022 to 2023, a cross-sectional survey was conducted to investigate the permanent population in Henan Province. Enzyme-linked immunosorbent assay (ELISA) was used to detect anti-pertussis toxin IgG (PT-IgG), analyze the antibody positivity rate (≥20 IU/ml) and median concentration (MC), and estimate the pertussis infection rate based on PT IgG ≥40 IU/ml. The rank sum test was used to compare antibody levels among groups, and the χ2 test was used to compare antibody positive rates and infection rates among groups. Results:A total of 4 810 research subjects were included in this study. The overall positive rate of PT-IgG was 12.10% and MC was 3.04 (0.35, 10.36) IU/ml. There were significant differences both in positive rates and antibody levels of PT-IgG among different regions or age groups (region positive rate: χ2=134.06, P<0.001, MC: H=337.74, P<0.001; age group positive rate: χ2=45.27, P<0.001, MC: H=134.49, P<0.001). Both the positive rate of PT-IgG (25.26%) and MC (8.01 IU/ml) were the highest within one year after completing a full course of vaccination. There were significant differences in positive rates and antibody levels among people receiving different types of pertussis vaccines (positive rate: χ2=12.38, P=0.006, MC: H=17.93, P<0.001). The antibody positivity rate (35.71%) and MC (8.88 IU/ml) of the people who received cell-free pertussis inactivated poliomyelitis influenza type b (combined) vaccine throughout the course were higher than those who received other types of vaccines. The natural infection rate of pertussis was evaluated for individuals aged≥3 years who had no history of pertussis vaccine immunization within the year prior to sampling. With a high vaccination rate, the estimated infection rate of pertussis in the population was 5 757.22/100 000. The infection rates in the 3-year-old (1 940.16/100 000) and 4-year-old (1 765.68/100 000) populations were at a low level among the entire population, reaching their peak at the age of 6 (12 656.71/100 000). Subsequently, although the infection rate continued to decline, it remained at a high level and peaked again at the age of 40-49 years (8 740.39/100 000). There was a statistically significant difference in the estimated infection rate of pertussis among different age groups ( χ2=53.21, P<0.001). Conclusion:The PT-IgG level of pertussis in the population of Henan Province is generally at a low level. The estimated infection rate of pertussis is much higher than the reported incidence rate. A booster dose of pertussis vaccine is recommended at 6 years old.

OBJECTIVE To provide a reference for continuing education and training of clinical pharmacists. METHODS The revision of the syllabus and the improvement of training methods of practical skills training class for clinical pharmacists in the neurology department held by Xuanwu Hospital of Capital Medical University from 2007 to 2022 was sorted to summarize its advantages and characteristics. RESULTS Training programs were developed to benefit clinical pharmacists at different levels, and the training contents were adjusted according to the training programs and the needs of trainees. Teachers with teaching experience were selected to participate in the teaching. Theory teaching was combined with practice teaching in the teaching process, and case teaching and question-based teaching methods were adopted to benefit both senior clinical pharmacists and new clinical pharmacists. In addition, the influence of the training class was expanded through online teaching, so that doctors and pharmacists could communicate and learn together on the platform of the training class. For example, when designing the training program, we replaced one common neurological disease every two years, and carried rollover study on its new progress and new ideas; clinical pharmacist skill course was reduced, drug history writing, information retrieval and test index interpretation were compressed into clinical pharmacy skill course. CONCLUSIONS The continuing education platform is established for clinical pharmacists; new knowledge and concepts that clinical pharmacists of this specialty need to be familiar with are compiled into the teaching syllabus, and the experts who are familiar with the training of clinical pharmacists are selected to explain to the students so that the students could follow the platform to constantly update their knowledge and improve the ability of clinical pharmacists to participate in the clinic work.

ObjectiveTo explore the anti-tumor effect and mechanism of Shenqi Yiliu prescription in the intervention of pyroptosis. MethodTen male BALB/c mice were randomly selected and assigned to the blank group. The remaining 40 mice underwent the induction of the liver cancer xenograft model. After 5 days of modeling, 40 surviving mice were randomly divided into model group, cisplatin group [2.5×10-3 g·kg-1·(3 d)-1], Shenqi Yiliu prescription group (27 g·kg-1·d-1), and a combination group (Shenqi Yiliu prescription group + cisplatin). The mice in the blank group and the model group were treated with an equal volume of normal saline for 10 days. The general conditions of mice in each group were observed. After the intervention, the tumor weight of the mice was weighed and the tumor inhibition rate was calculated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in tumor tissues. The levels of mouse liver function indicators, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected. The TdT-mediated dUTP-biotin nick end labeling (TUNEL) assay was used to detect DNA damage in mouse tumor tissue cells. Immunohistochemistry (IHC), immunofluorescence (IF), and Western blot were used to detect the protein expression levels of NOD-like receptor protein 3 (NLRP3), cysteinyl aspartate-specific protease-1 (Caspase-1), and gasdermin D (GSDMD) in tumor tissues. The levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) in tumor tissues were detected by enzyme-linked immunosorbent assay (ELISA). ResultCompared with the mice in the blank group, those in the model group were in a poor mental state, sleepy, and lazy, and their fur color was dull, with increased levels of serum ALT and AST in liver function tests (P<0.01). Compared with the model group, the groups with drug intervention showed improved mental state, inhibited tumor growth to varying degrees, and decreased tumor weight, and the tumor inhibition rate in the combination group was the highest (P<0.01). HE staining showed that the pathological and morphological lesions of the tumor tissues in the model group were significant, while those in all groups with drug intervention were improved to a certain extent. The karyolysis and nuclear rupture in the Shenqi Yiliu prescription group and the combination group were more significant. In the liver function test, the serum ALT and AST levels of mice in the Shenqi Yiliu prescription group and the combination group decreased (P<0.01), and the inflammatory factors IL-1β and IL-18 in each group with drug intervention decreased (P<0.05, P<0.01). Among them, the declining trend of IL-1β and IL-18 in the Shenqi Yiliu prescription group was the most significant (P<0.01). TUNEL staining showed that the positive TUNEL staining in each group with drug intervention decreased after intervention (P<0.05, P<0.01), especially the cisplatin group and Shenqi Yiliu prescription group (P<0.01). Western blot, IHC, and IF found that the protein expression levels of NLRP3, Caspase-1, and GSDMD in each group with drug intervention decreased (P<0.05, P<0.01). Compared with the mice in the cisplatin group, those in the Shenqi Yiliu prescription group and the combination group had better mental state and regular tumor morphology, and the tumor weight of the mice in the combination group decreased (P<0.05). The levels of ALT and AST in the Shenqi Yiliu prescription group decreased (P<0.05), and the levels of IL-1β and IL-18 in the Shenqi Yiliu prescription group and the combination group decreased (P<0.05, P<0.01), especially in the combination group (P<0.01). The results of IHC showed that the expression of GSDMD protein in the tumor tissues of mice in the combination group was reduced (P<0.01). IF detection showed that the expression of NLRP3 in the tumor tissues of the Shenqi Yiliu prescription group was reduced (P<0.01). The results of Western blot showed that the expression level of NLRP3 protein in the Shenqi Yiliu prescription group and the combination group decreased (P<0.01), and the expression level of Caspase-1 protein in the combination group decreased (P<0.01). The decrease in GSDMD protein expression was not significant, and the difference was not statistically significant. ConclusionShenqi Yiliu prescription combined with cisplatin has an obvious anti-tumor effect, which may be achieved by down-regulating the NLRP3/Caspase-1/GSDMD inflammatory pyroptosis pathway to inhibit cell pyroptosis, and relieve the inflammatory response in mice with liver cancer.

The p21 activated kinase 4 (PAK4) is serine/threonine protein kinase that is critical for cancer progression. Guided by X-ray crystallography and structure-based optimization, we report a novel subseries of C-3-substituted 6-ethynyl-1H-indole derivatives that display high potential and specificity towards group II PAKs. Among these inhibitors, compound 55 exhibited excellent inhibitory activity and kinase selectivity, displayed superior anti-migratory and anti-invasive properties against the lung cancer cell line A549 and the melanoma cell line B16. Compound 55 exhibited potent in vivo antitumor metastatic efficacy, with over 80% and 90% inhibition of lung metastasis in A549 or B16-BL6 lung metastasis models, respectively. Further mechanistic studies demonstrated that compound 55 mitigated TGF-β1-induced epithelial-mesenchymal transition (EMT).
