Objective This study aimed to explore the prescription regularity of Mercury(Zuotai)detoxification formula in Tibetan classic medical literatures based on data mining.Methods Mercury(Zuotai)detoxification formula of were collected from 22 ancient Tibetan medical literatures including the Four Medical Tantras,Medicine of Moon King,One Hundred Thousand Fists and Eight Essential Collections of Medicine,et al.The database of drugs,medicinal properties,five-source,six-flavor,and three-chemical flavor was established.R 4.2.2,IBM SPSS Modeler 18.0,Origion 2024 and other software were used to conduct frequency statistical analysis,Apriori association rule analysis and cluster analysis of the category,property and flavor,and five-source of Mercury(Zuotai)detoxification compound drugs,and interpret the statistical results in combination with the theory of Tibetan medicine.Results A total of 52 formulas were collected,containing 213 Tibetan medicines,with a cumulative frequency of 1066 times.The medicines involved in the prescription are mainly plant-based,and most of them are"cold"drugs;the medicinal flavor of drugs is mainly bitter,sweet,and pungent,with the five sources of emptiness,wind and water predominating;the most frequently occurring medicine was Mercury(Zuotai),followed by Terminalia Chebula,Musk,Geranium,Saffron,and Nutmeg.High-frequency medicines such as Mercury(Zuotai),Musk,Strychni Semen,Aconitum Tanguticum,Pedicularis Trichoglossa,Swertia Verticillifolia,and Sinapis Alba have detoxification effects.Musk also has the effect of aromatherapy,Terminalia Chebula can reconcile the nature of the medicine and the three causes of the disease effectively.The"six good medicines",including Geranium,Saffron,Nutmeg,White cardamom,Cloves,and Tsaoko Amomum Fruit,can harmonize qi and blood,and treat diseases of internal organs of the body.The analysis of association rules showed 24 pairs of medicines combinations with a support degree exceeding 59.62,and 9 groups of three-drug combinations,predominantly involving Mercury(Zuotai),Terminalia Chebula,Musk,and"six good medicines".The cluster analysis of medicines with a frequency of>10 produced 7 clustered formulas,primarily characterized by their efficacy in clearing away heat and toxins,as well as regulating the five internal organs and six viscera.Conclusion Most medicines in the Mercury(Zuotai)detoxification formula are primarily composed of botanicals,cold and bitter drugs,which is consistent with the heat-clearing and detoxifying therapy in Tibetan medicine.The medication pattern of the Mercury(Zuotai)detoxification formula is characterized by the use of Terminalia Chebula to reconcile the medicinal properties,detoxifying medicines to detoxify,aromatic drugs to rapidly eliminate or expel toxins,and six good medicines to protect the viscera.The combined use of these medicines plays a role in clearing away heat and toxins,opening up the orifices and collaterals,and harmonizing the functions of the viscera.The study provides data to support the medication rules of the Tibetan medicine Mercury(Zuotai)detoxification prescription.

Objective:To construct a prediction model for ventilator-associated pneumonia (VAP) in mechanically ventilated preterm infants in the neonatal intensive care unit (NICU) and to test its clinical effect.Methods:This was a cross-sectional study. A total of 740 preterm infants admitted to the NICU for mechanical ventilation from July 2018 to June 2023 were retrospectively selected as the study subjects, and were divided into the modeling set (518 cases) and the validation set (222 cases) according to the ratio of 7∶3 using the computer-generated random number method. The modeling set was divided into the VAP group (181 cases) and the non-VAP group (337 cases) according to whether VAP occured, and 21 clinical characteristics were analyzed, using single factor difference analysis to screen predictive factors, the independent risk factors of VAP in mechanically ventilated preterm infants were determined by multivariate Logistic regression analysis, and the nomogram model was made by R software. Then, the nomogram model was tested by validating the data of the validation set. The receiver operating characteristic (ROC) curve, Hosmer-Lemeshow goodness-of-fit test, calibration curve and clinical decision curve were used to evaluate the efficacy and practical value of the model.Results:There were 88 males and 93 females in the VAP group, with 156 cases of gestational age<34 weeks and 25 cases of gestational age≥34 weeks. There were 155 males and 182 females in the non-VAP group, with 196 cases of gestational age<34 weeks and 141 cases of gestational age≥34 weeks. Birth weight ( OR=0.114, 95% CI 0.044-0.268, P<0.05) and oral care of breast milk ( OR=0.124, 95% CI 0.0.057-0.249, P<0.05) were protective factors for VAP in mechanically ventilated preterm infants, and Apgar score at 5 min after birth ( OR=2.895, 95% CI 1.318-6.419, P<0.05), serum prealbumin at 72 h of mechanical ventilation ( OR=4.837, 95% CI 2.643-9.063, P<0.05), gastric contents reflux ( OR=6.754, 95% CI 3.156-15.240, P<0.05), and time of mechanical ventilation ( OR=7.784, 95% CI 3.491-18.160, P<0.05) were independent risk factors for VAP in mechanically ventilated preterm infants. The area under the curve (AUC) of the ROC curve of the modeling set was 0.929 (95% CI 0.907-0.950, P<0.01), and the validation set (AUC) was 0.917 (95% CI 0.882-0.952, P<0.01), the model has good discrimination. The C indices of the modeling set and the validation set were 0.93 and 0.92 respectively by sampling 500 times by the Bootstrap method, indicating that the model had good consistency, and the decision curve suggested that the prediction model was far from the extreme curve and the net return value was high, indicating that the nomogram prediction model constructed this time had high prediction value. Conclusions:Birth weight, Apgar score at 5 min after birth, time of mechanical ventilation, oral care of breast milk, serum prealbumin at 72 h of mechanical ventilation, and gastric contents reflux are independent influencing factors for VAP in mechanically ventilated preterm infants. The nomogram prediction model constructed can provide a visual and simple evaluation tool for early identification of high-risk children and reducing the occurrence of VAP.

Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.

【Objective:】 To understand the current status of narrative nursing knowledge, attitude, and practice (KAP) among nurses in grade A tertiary hospitals, and to provide a basis for the development of narrative nursing in relevant areas. 【Methods:】 Using convenience sampling methods, 931 nurses from three grade A tertiary hospitals in Xi’an were selected as subjects. A cross-sectional survey was conducted using the Clinical Nurses’ Narrative Nursing Knowledge and Trustworthiness Questionnaire and the General Self-Efficacy Scale. Multiple linear regression analysis was used to explore the influencing factors of nurses’ narrative nursing KAP. 【Results:】 The scores on the three dimensions of narrative nursing KAP were (23.70±2.99) points, (31.69±5.92) points, and (30.26±5.32) points, respectively. Nursing workload, general self-efficacy, professional title, and nursing satisfaction were the influencing factors of nurses’ narrative nursing knowledge dimension (P<0.05). There were statistically significant differences in nurses’ narrative nursing attitude dimension among nursing workload, general self-efficacy, professional title, monthly income, and nursing satisfaction (P<0.05). Nursing workload, general self-efficacy, nursing satisfaction, and accompanying experience were the influencing factors of nurses’ narrative nursing behavior dimension (P<0.05). 【Conclusion:】 Nurses in grade A tertiary hospitals have moderate narrative nursing knowledge, positive attitudes, and poor practice execution. The high nursing workload is the main barrier factor for the current development of narrative nursing. Nursing managers should actively build a diversified training system and guarantee system to boost the development of narrative nursing in clinical nursing work, and further promote the development of narrative nursing concepts.

Objective To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on upper limbs function in chronic stroke patients. Methods From March, 2016 to May, 2018, 53 patients were randomly divided into control group (n = 27) and research group (n = 26). All the patients received conventional rehabilitation, and the research group received additional intervention of TEAS, for six weeks. They were assessed with Manual Muscle Test (MMT) on upper limbs, modified Ashworth Scale (MAS), Fugl-Meyer Assessment-upper extremities (FMA-UE), Hand Motor Status Scale and modified Barthel Index (MBI) before, at the end of 6-week treatment and twelve weeks after treatment. Results There was no significant difference in all the scores between two groups at the end of 6-week treatment (t < 1.511, P > 0.05). The scores of MMT of wrist dorsal extension, FMA-UE and MBI were better in the research group than in the control group twelve weeks after end of treatment (t > 2.312, P < 0.05). Conclusion TEAS may promote the recovery of hands and upper limbs function in chronic stroke patients.
