Objective To systematically evaluate toxicities of nifedipine in pregnant women with hypertension, and provide references for nifedipine’s clinical safety application. Methods Study was conducted with data from US food and drug administration adverse event reporting system（FARES） database from January 1, 2015, to March 31, 2021. Information component （IC） and reporting odds ratio（ROR）methods were applied for signal mining. Results Finally, a total of 539278 records of pregnant women with hypertension were selected for analysis, and 70 positive adverse drug event signals were detected. Premature delivery （IC₀₂₅=2.87，ROR₀₂₅=9.52）, pre-eclampsia （IC₀₂₅=1.82，ROR₀₂₅=3.82） and fetal growth restriction （IC₀₂₅=2.37，ROR₀₂₅=5.69）were positive adverse events with higher frequency. Polydactyly（IC₀₂₅=3.13， ROR₀₂₅=10.05）, fetal death（IC₀₂₅=2.93，ROR₀₂₅=8.57）and premature delivery（IC₀₂₅=2.87，ROR₀₂₅=9.52）were positive adverse events with higher intensity. Vascular resistance systemic increased, small for dates baby and fetal death corresponded to higher death rates. Conclusion Nifedipine-associated drug toxicities were detected in pregnant women with hypertension, and some adverse events with high frequency and high death rate were deserved further attention by medical staffs.

Objective:To explore the status quo and influencing factors of palliative care self-report practice among oncology nurses and provide references and directions for improving the palliative care practice of oncology nurses.Methods:This is a cross-sectional study. Totally 349 oncology nurses from four hospitals in Hangzhou were selected by convenience sampling from June to December 2022. Data were collected using a general information questionnaire, the Palliative Care Self-Report Practice Scale (PCPS), and the Palliative Care Knowledge Questionnaire. Pearson correlation analysis was used to explore the relationship between PCPS scores and palliative care knowledge scores among oncology nurses. Multiple linear regression analysis was employed to identify the influencing factors of palliative care self-report practice.Results:A total of 349 questionnaires were distributed, with 332 valid responses, resulting in an effective response rate of 95.13% (332/349). The total PCPS score among the 332 oncology nurses was (42.16±4.52). Among the six dimensions, the dyspnea dimension had the highest average item score of (2.85±0.54), while the communication dimension had the lowest average item score of (2.03±0.54). There was a positive correlation between PCPS scores and palliative care knowledge scores ( P<0.01). Multiple linear regression analysis indicated that years of work experience, attitude towards palliative care, understanding of palliative care, and palliative care knowledge scores were influencing factors of palliative care self-report practice among oncology nurses ( P<0.01), accounting for 66.30% of the total variance. Conclusions:The palliative care self-report practice of oncology nurses is at a moderate level and is influenced by various factors. Hospital leaders should provide individualized and diversified palliative care education and training aimed at improving palliative care practices. This should involve multiple approaches and levels to enhance the nurses' mastery of palliative care knowledge and clinical skills, thereby improving the quality of palliative care services and patient satisfaction.

Objective:To explore the application effect of the modified presentation assimilation discussion combined with heuristic clinical medicine teaching in training of extracorporeal membrane oxygenation specialist nurses.Methods:The convenient sampling method was used to select 62 nurses who participated in training of extracorporeal membrane oxygenation specialist nurses in the Second Affiliated Hospital of Zhengzhou University from January to June 2023 as the research objects. A total of 30 nurses who participated in the 25th training session from January to March 2023 were selected as the control group, and 32 nurses who participated in the 26th training session from April to June 2023 were selected as the observation group. The control group received conventional training method, while the observation group received modified presentation assimilation discussion combined with heuristic clinical medicine teaching. The theoretical knowledge and operational skills of nurses, core competence of extracorporeal membrane oxygenation specialist nurses and training satisfaction were compared between the two groups after training.Results:After training, the scores of theoretical knowledge and operational skills, core competence of extracorporeal membrane oxygenation specialist nurses and training satisfaction in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05) . Conclusions:The modified presentation assimilation discussion combined with heuristic clinical medicine teaching can improve the theoretical knowledge and operational skills of extracorporeal membrane oxygenation specialist nurses, and the nurses' training satisfaction is higher.

Objective To analyze the characteristics of time in range(TIR)and its relationship with oxidative stress(OS)and insulin resistance status(HOMA-IR)in patients with type 2 diabetes mellitus(T2DM)and sleep apnea-hypopnea syndrome(OSAHS).Methods According to apnea-hypopnea index(AHI),165 T2DM in patients were divided into simple T2DM group(AHI<5 times/h,n=43),T2DM combine OSAHS mild group(OSAHS-G,5≤AHI<15 times/h,n=51),T2DM combined OSAHS moderate group(OSAHS-M,15≤AHI≤30 times/h,n=40)and T2DM combine OSAHS severe group(OSAHS-S,AHI>30 times/h,n=31).TIR was calculated by dynamic blood glucose monitoring.Superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and other indexes were detected and analyzed.Results Compared with simple T2DM group,the levels of HOMA-IR,8-iso-PGF2a and Ox-LDL were higher in T2DM combined OSAHS-G,OSAHS-M or OSAHS-S group,while the levels of TIR,SOD and GSH-Px were lower(P<0.05).Pearson correlation analysis showed that TIR was positively correlated with the levels of SOD and GSH-Px(P<0.05 or P<0.01),and negatively correlated with the levels of 8-iso-PGF2a,Ox-LDL,HbA1c,HOMA-IR and the severity of OSAHS(P<0.01).Logistic regression analysis showed that TIR,SOD and GSH-Px were protective factors for severe OSAHS in T2DM patients,while 8-iso-PGE2a and Ox-LDL were the risk factors for severe OSAHS.Conclusions The glucose level fluctuates greatly in patients with T2DM and OSAHS.Insulin resistance and oxidative stress are factors that affect the normalization of TIR.

Objective:To investigate the expression of anaplastic lymphoma kinase (ALK), tropomyosin receptor kinase (TRK), and recombinant C-Ros oncogene 1, receptor tyrosine kinase (ROS1) in Spitz tumors, and to analyze their associations with clinical and histopathological features of Spitz tumors.Methods:Clinical and histopathological characteristics, as well as follow-up data, were collected from patients with Spitz tumors at Department of Pathology, Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2017 to August 2023, and retrospectively analyzed. Immunohistochemical staining for ALK, pan-TRK, and ROS1 was performed on skin tissues, and associations between the expression of these kinase proteins and clinicopathological features were analyzed.Results:A total of 57 patients with Spitz tumors were collected, including 36 females and 21 males. Immunohistochemical staining showed that 30 (52.6%) patients were positive for ALK, 4 (7.0%) were positive for ROS1, only 2 (3.5%) were positive for TRK, and 21 (36.8%) were negative for the three kinase proteins. Among the 30 ALK-positive patients, the median age was 9.5 years, 21 (70.0%) were females, and 15 (50.0%) presented with lesions on the face, which mainly manifested as papules or nodules; histologically, 29 (96.7%) patients had hypopigmented tumors with an exophytic growth pattern, and the tumor cells were mainly large and long spindle cells arranged in long cord-like, plexiform or fascicular patterns. Among the 4 ROS1-positive patients, there were 3 females and 1 male, presenting with exophytic papules or polyps; histologically, tumor cells were mostly arranged in small nests, without obvious clefts around cell nests. Two TRK-positive patients were both males aged 20 and 50 years respectively, and presented with brown and skin-colored flat papules, respectively; histologically, the tumors were located superficially with a flat base, and tumor cells spread in a pagetoid pattern in the epidermis, with some epithelioid cells and small cell nests. Among the 21 patients negative for the 3 kinase proteins, 9 were males and 12 were females, and they clinically presented with macules, papules and polypoid lesions; histologically, most tumors were located superficially, consisting of a mixture of epithelioid cells and spindle cells, with rare cytological atypia and mitotic figures, and 2 cases showed mild tissue structural and cellular atypia. Fifty-seven patients were followed up for 2 - 83.3 months, with a median follow-up of 19.2 months. Only 1 ALK-positive child experienced a recurrence, and no recurrence or lymph node metastasis was observed in the other cases.Conclusions:Among the three kinase proteins, ALK showed the highest positive rate in Spitz tumors in this study, while TRK- and ROS1-positive cases were sporadic. Histopathologically, ALK-positive Spitz tumor cells were mainly long spindle cells arranged in long cord-like or plexiform patterns, while TRK- and ROS1-positive Spitz tumors tended to have small cell nests. Both the kinase protein-positive and -negative Spitz tumors mostly had a good prognosis.

[Objective]To investigate the current situation and demand of classical education in the standardized training of traditional Chinese medicine(TCM)residents,to help reform the model of Chinese-style training.[Methods]The questionnaire made by the experts of the research group was used to investigate the doctors in 4 bases and statistical analysis was made.[Results]A total of 362 participants were investigated,and 348 questionnaires were included in statistical analysis,with an effective rate 96.1%.For the current situation,the main diagnosis and treatment thinking formed under the current training mode was"mixed Chinese and western,neither eastern nor western".For the problems and reasons,the proportion of classical study,examination and practice were all low.It was related to identity attribute,training years,training state and so on.For the requirement,most participants supported the inclusion of classical education in the reform of the training system.It was hoped that under the premise of not increasing the total workload,a certain proportion of classical contents can be added by digital means to cultivate the thinking of TCM diagnosis and treatment,such as Treatise on Febrile Diseases,Synopsis of Golden Chamber and Huangdi's Inner Classic.[Conclusion]Based on the training goal of TCM diagnosis and treatment thinking,the current training mode needs to be reformed to reflect the characteristics of TCM.TCM classics are the keys to highlight the characteristics of TCM,and training classic thinking is core content of TCM diagnosis and treatment thinking.At present,the training of classics and classical thinking is seriously insufficient in the process of training.Digital technology brings the possibility to the intelligent transformation of classical thinking.It can comprehensively evaluate the mastery level of TCM classics and the ability of translating classical thinking into clinical practice.

Objective: To investigate the effects of after school exercise service (referred to as the "after school ES") on physical health, so as to provide evidence for possible beneficial effect of after school ES. Methods: Students in the fourth grade of primary school were recruited from September 2021 to July 2022 in Changsha City and divided into the control group ( n =220) and the after school ES group ( n =220). The control group only participated in the regular physical education activities of the school. The after school ES group received after school ES for one academic year, 4 times a week, 40-50 minutes per time, for a total of 32 weeks. Body shape indicators such as height, weight and percentage of body fat, as well as physical fitness indicators such as 50 meter running, grip strength and progressive aerobic cardiovascular endurance run (PACER) were measured in September to October 2021 and June to July 2022, respectively. Independent sample t-test, Chi square test and two factors repeated measurement analysis of variance were used for statistical analysis of the data. Results: After one academic year, compared with the control group [(13.52±2.30)kg], muscle mass of primary school students in the after school ES group [(13.76±2.32)kg] significantly increased, while waist to hip ratio [(0.95±0.16)] and percentage of body fat [(20.17±7.43)%] significantly decreased compared to the control group [(1.01±0.21), (22.02±12.34)%]( F=330.70, 6.85, 4.33, P <0.05). The proportion of overweight and obesity in after school ES group decreased significantly from 19.5% to 12.3% ( χ 2=4.35, P <0.05). Compared with the control group, the scores of 50 meter running [(10.00±1.06, 10.21±0.83)s], 1 minute sit up [(33.25±8.24, 30.76±9.34)times], sitting and flexion [(14.53±7.50, 8.59±6.32)cm], 1 minute rope skipping [(125.01±30.50, 115.97±32.09)times], eyes closed and single legged standing [(30.00±34.72, 25.72±23.82)s], selective response time [(635.66±91.72, 652.79±120.42)ms] and VO 2max [(45.31± 1.02 , 43.67±0.85)mL/(kg〖 ·min)] in the after school ES group were significantly improved, with statistical significance ( F= 5.32 , 443.14, 97.23, 814.07, 36.49, 6.11, 396.91, P <0.05). Conclusions After school ES can improve body shape of primary school students, reduce the risk of overweight and obesity and enhance physical fitness. It is recommended that schools should appropriately increase after school ES to promote physical fitness of students.

Foot ulcer prevention plays a crucial role in reducing the amputation rate among diabetic patients. With regard to the prevention of diabetic foot ulcers, the 2023 guidelines of the International Working Group of Diabetic Foot(IWGDF) were different from the 2019 counterpart. The most notable change is the addition of high-level evidence to support recommendations, primarily derived from randomized controlled studies. The 2023 guidelines also advocate for local skin temperature measurement, participation in ankle exercise training, and psychological intervention for foot ulcer prevention. This article conducts a comparative analysis of the two guidelines across six key dimensions: identification of high-risk feet, regular examination of high-risk feet, health education, ensuring appropriate daily footwear, addressing ulcer risk factors, and comprehensive foot care. Drawing from clinical insights, the application and prospective implications of the 2023 guidelines in China are also examined.
