OBJECTIVE To investigate the application status of prescription pre-review systems in healthcare institutions of Yunnan province， evaluate their system functions and management capabilities， and provide a practical basis for promoting rational drug use. METHODS A questionnaire survey was conducted among public healthcare institutions at or above the secondary level in Yunnan province to investigate the deployment status of the systems. A capability maturity assessment framework was constructed， encompassing 6 dimensions and 39 indicators， including real-time prescription review， prescription correlation review， rule setting， evidence-based information support， prescription authority management， and system operation management. This framework was then used to evaluate the institutions that had implemented the pre-review systems. RESULTS A total of 100 valid questionnaires were collected， with 37 institutions having adopted prescription pre-review systems， mainly tertiary hospitals. The system predominantly adopted a modular architecture and was embedded into the hospital information system through application programming interfaces and middleware， providing certain capabilities for real-time prescription risk identification. Evaluation results indicated that basic functions such as reviewing indications， contraindications， and drug compatibility performed well， while deficiencies remained in functions related to parenteral nutrition prescription， review of drug dosage for specific diseases， individual patient characteristic recognition， and rule setting. Moreover， the construction of review centers and establishment of management systems were also not well-developed. CONCLUSIONS The overall application rate of prescription pre-review systems in Yunnan province remains low. System functions and management mechanisms require further improvement. It is recommended to enhance information infrastructure in lower-level institutions and explore regionally unified review models to promote standardized and intelligent development of prescription review practices.

The decrease in blood glucose in perinatal dairy cows affects the energy supply and im-mune function of peripheral blood neutrophils(PMN).Fibroblast growth factor 21(FGF21)is an important regulator of glucose metabolism,and serum FGF21 levels in some perinatal cows are significantly elevated after farrowing.In order to explore the effect of FGF21 on PMN glucose ho-meostasis in perinatal dairy cows,the cows were divided into high FGF21 group(high FGF21,n=8,FGF21＞800 ng/L)and low FGF21 group(low FGF21,n=8,FGF21＜200 ng/L)within 3 weeks postpartum.The results showed that compared with the low FGF21 group,the glucose up-take of PMN and the mRNA expression of glucose transporters SLC2A1 and SLC2A3 were signifi-cantly increased in the high FGF21 group.The activities of phosphofructokinase 1(PFK1)and glu-cose-6-phosphate dehydrogenase(G6PDH)were significantly increased,and the activity of glyco-gen synthase(GCS)was significantly decreased in PMN in the high FGF21 group.The lactate con-tent and ATP content of PMN were significantly increased,and the mRNA and protein expressions of hexokinase(HK2)and PFK1 were significantly increased in the high FGF21 group.These re-sults indicated that the uptake and utilization of glucose by PMN in perinatal peripheral blood FGF21 increased to ensure the ATP supply of PMN,which provided a theoretical basis for the pro-posal of a new strategy to alleviate immunosuppression in perinatal dairy cows.

Objective:To investigate the mediating effect of work engagement on the relationship between nurses′ perception of authentic leadership and their innovative behavior, providing insights for enhancing nurses′ innovative practices.Methods:A convenience sampling method was employed to recruit registered nurses from 37 hospitals in Anhui Province between January and March 2022. The Authentic Leadership Questionnaire, Utrecht Work Engagement Scale and Nurse Innovative Behavior Scale were utilized to conduct a cross-sectional survey. SPSS 25.0 was used to analyze the correlations among nurses′ perception of authentic leadership, work engagement, and innovative behavior, while AMOS 26.0 was employed to assess the mediating effect of work engagement between nurses′ perception of authentic leadership and innovative behavior.Results:A total of 3 200 questionnaires were distributed, and 2 994 valid questionnaires were collected. Among the 2 994 participating nurses, 2 907 (97.1%) were female and 87 (2.9%) were male, 1 002 (33.5%) aged 22-25 years, 1 374 (45.9%) aged 26-39 years, 467 (15.6%) aged 40-49 years, and 151 (5.0%) aged 50 years or older. The total scores of the Authentic Leadership Questionnaire, Utrecht Work Engagement Scale and Nurse Innovative Behavior Scale were (68.23 ± 13.15), (51.49 ± 11.65) and (38.28 ± 8.35) points, respectively. Pearson correlation analysis revealed significant positive correlations between nurses′ perception of authentic leadership and work engagement ( r=0.473, P<0.01), between nurses′ perception of authentic leadership and innovative behavior ( r=0.530, P<0.01), and between work engagement and innovative behavior ( r=0.553, P<0.01). The mediating effect analysis indicated that work engagement partially mediates the relationship between nurses′ perception of authentic leadership and innovative behavior ( β=0.18, P<0.01), with a mediation effect ratio of 34.62%. Conclusions:Nurses′ perception of authentic leadership can indirectly influence their innovative behavior through work engagement. It is recommended that nursing managers prioritize the enhancement of authentic leadership and foster work engagement among nurses to stimulate their innovative behavior.

Objective    To investigate the clinical effect of 3D computed tomography bronchial bronchography and angiography (3D-CTBA) and guidance of thoracoscopic anatomic pulmonary segmentectomy by Mimics software system. Methods    A retrospective analysis was performed on patients who underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of Affiliated People's Hospital of Jiangsu University from June 2020 to December 2022. The patients who underwent preoperative 3D-CTBA using Materiaise's interactive medical image control system (Mimics) were selected as an observation group, and the patients who did not receive 3D-CTBA were selected as a control group. The relevant clinical indicators were compared between the two groups. Results    A total of 59 patients were included, including 29 males and 30 females, aged 25-79 years. There were 37 patients in the observation group, and 22 patients in the control group. The operation time (163.0±48.7 min vs. 188.8±43.0 min, P=0.044), intraoperative blood loss [10.0 (10.0, 20.0) mL vs. 20.0 (20.0, 35.0) mL, P<0.001], and preoperative puncture localization rate (5.4% vs. 31.8%, P=0.019) in the observation group were better than those in the control group. There was no statistically significant difference in the thoracic tube placement time, thoracic fluid drainage volume, number of intraoperative closure nail bin, postoperative hospital stay, or postoperative air leakage incidence (P>0.05) between the two groups. Conclusion    For patients who need to undergo anatomical pulmonary segmentectomy, using Mimics software to produce 3D-CTBA before surgery can help accurately identify pulmonary arteriovenous anatomy, reduce surgical time and intraoperative blood loss, help to determine the location of nodules and reduce invasive localization before surgery, and alleviate patients' pain, which is worthy of clinical promotion.

Objective:To develop a risk assessment tool for chemotherapy induced nausea and vomiting after transcatheter arterial chemoembolization in patients with primary liver cancer, and to verify its predictive efficiency, so as to provide reference for risk assessment and nursing intervention of nausea and vomiting in patients with primary liver cancer.Methods:A cross-sectional survey was used. The risk assessment tool was compiled by using literature analysis, Delphi expert consultation and analytic hierarchy process. 153 patients with primary liver cancer who underwent transcatheter arterial chemoembolization in the Department of Intervention, Jiangsu Cancer Hospital from May 2022 to April 2023 were selected for assessment by using convenience sampling method. Receiver operating characteristic curve, sensitivity, specificity and Youden index were used to test the prediction efficiency of risk assessment tools.Results:Among 153 patients, there were 78 males, 75 females, aged (48.44 ± 7.76) years old. The expert positive coefficient of the three rounds of inquiry letters was all 100%, the expert authority coefficient was 0.936, 0.950 and 0.960 respectively, and the Kendall harmony coefficient was 0.490, 0.327 and 0.414 respectively (all P<0.01). The risk assessment tool for chemotherapy induced nausea and vomiting after transcatheter arterial chemoembolization in patients with primary liver cancer included 14 items. The results of prediction efficiency analysis showed that the area under the receiver operating characteristic curve was 0.938 (95% CI 0.903-0.974, P<0.01). When the cut-off score was 56.2, the sensitivity, specificity and Youden index of the risk assessment tool were 0.926, 0.881 and 0.807, which had the best prediction efficiency. Conclusions:The risk assessment tool for chemotherapy induced nausea and vomiting after transcatheter arterial chemoembolization in patients with primary liver cancer has high scientificity, predictive efficiency and practicability, and is suitable for the risk assessment for chemotherapy induced nausea and vomiting after transcatheter arterial chemoembolization in patients with primary liver cancer in China.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.
