Chronic cerebral hypoperfusion leads to white matter injury (WMI), which plays a significant role in contributing to vascular cognitive impairment. While 13-docosenamide is a type of fatty acid amide, it remains unclear whether it has therapeutic effects on chronic cerebral hypoperfusion. In this study, we conducted bilateral common carotid artery stenosis (BCAS) surgery to simulate chronic cerebral hypoperfusion-induced WMI and cognitive impairment. Our findings showed that 13-docosenamide alleviates WMI and cognitive impairment in BCAS mice. Mechanistically, 13-docosenamide specifically binds to cannabinoid receptor 1 (CNR1) in oligodendrocyte precursor cells (OPCs). This interaction results in an upregulation of ubiquitin-specific peptidase 33 (USP33)-mediated CNR1 deubiquitination, subsequently increasing CNR1 protein expression, activating the phosphorylation of the AKT/mTOR pathway, and promoting the differentiation of OPCs. In conclusion, our study suggests that 13-docosenamide can ameliorate chronic cerebral hypoperfusion-induced WMI and cognitive impairment by enhancing OPC differentiation and could serve as a potential therapeutic drug.

Objective: The objective of this study was to identify the risk factors for postoperative pathological escalation of endometrial cancer in patients with a pathologic diagnosis of endometrial intraepithelial neoplasia (EIN) before surgery. Some of the clues from the preoperative assessment were used to build a nomogram to predict the likely pathological escalation after surgery, and to explore the feasibility of sentinel lymph node biopsy in these patients with possible pathological escalation. Methods: This was a retrospective analysis of patients who underwent surgical treatment for EIN diagnosed before surgery between 2018 and 2023 in The Obstetrics and Gynecology Hospital of Fudan University. parameters including clinical, radiological and histopathological factors were analyzed by univariate and multivariate logistic regression to determine the correlation with pathology upstaging. A nomogram based on the multivariate results was developed to predict the probability of pathology upstaging. A total of 729 patients were included, divided into training set and validation set. 484 patients were used to build the model. This nomogram was subsequently validated using 245 patients. Results: Upstaging to endometrial carcinoma occurred in 115 (23.8 percent) of 484 women treated between 2018 and 2023 in training set. A lager endometrial thickness (at least 15 mm), menopause, hypertension, HE4, and endometrial blood were significantly associated with upstaging. A nomogram developed using these factors demonstrated good predictive performance (area under the receiver operating characteristic curve (AUC)=0.6808; 95% confidence interval [CI]=0.6246–0.7369). The nomogram showed similar predictive performance in the validation data set, based on another 245 women (AUC=0.7821; 95% CI=0.7076–0.8567). Conclusion This study developed a novel nomogram based on the 5 most important factors, which can accurately predict invasive cancer. It is common for women with preoperative diagnosis of EIN to experience pathological progression to endometrial cancer. For some patients with postoperative pathological escalation, we found lymph node metastasis. This nomogram may be useful to help doctor decide whether to perform sentinel lymph node biopsy for surgical staging in these EIN patients. According to the nomogram, simultaneous sentinel lymph node biopsy in patients with high probability of postoperative pathological upgrading can provide better guidance for postoperative adjuvant treatment of endometrial cancer and avoid the occurrence of secondary surgery.

Objective To systematically analyze the domestic and foreign literature related to interventional nursing care for patients with coronary heart disease in the past 10 years and to make a further understanding of the research status,hot spots and trends in this field so as to provide useful reference for the in-depth research in this field.Methods A computerized retrieval of academic papers concerning the interventional nursing care for patients with coronary heart disease from the databases of CNKI,Wanfang,VIP-CMJD,PubMed and Web of Science was conducted.The retrieval time period was from 1 January,2014 to February 27,2024.NoteExpress and CiteSpace software were used to make visualization analysis for the literature meeting the inclusion and exclusion criteria.Results A total of 4 098 Chinese articles and 381 English articles were enrolled in the analysis.Between 2014 and 2021,the number of domestic and foreign documents was on the rise.The number of foreign publications continued to increase in 2022,thereafter,the number of publications was declined in 2023.The authors with the most published academic papers were WANG Jing(15 articles)and Ayman Elbadawi(7 articles).The research keywords involved a wide range,and the research focus was on the characteristics and perioperative care of coronary heart disease,including quality of life,evidence-based nursing care,complications,myocardial infarction,outcome,mortality,etc.The obvious trend of research was to emphasize the psychological nursing,continuation nursing and rehabilitation nursing for patients with coronary heart disease receiving interventional treatment.Conclusion Although the number of research publications concerning the interventional nursing care for patients with coronary heart disease in the past decade is very large,the authors and institutions lack effective communication and collaboration.In order to improve the overall health,self-care ability and quality of life of patients,the future studies should further strengthen the quality of research,focus on key population,and innovate nursing pattern.

Objective:To observe the clinical efficacy of combined acupuncture and medication therapy in treating cerebral infarction in the acute stage and its impact on cerebral blood flow.Methods:A total of 160 patients with cerebral infarction were divided into 4 groups using the random number table method,with 40 cases in each group.Conventional treatment was given to all groups.Besides,the Chinese medication group received Tong Shen Fu Nao Wan;the acupuncture group received Xing Nao Kai Qiao(mind-refreshing and orifice-opening)needling therapy;the acupuncture-medication group received both Tong Shen Fu Nao Wan and Xing Nao Kai Qiao needling therapy.After 4 weeks of treatment,the clinical efficacy was assessed,and changes in the traditional Chinese medicine(TCM)symptom score and hemodynamics were compared among the four groups,as well as complications and adverse reactions.Results:After treatment,the acupuncture-medication group had a higher total effective rate compared to the other three groups(P<0.05).After the intervention,the National Institutes of Health stroke scale(NIHSS)score dropped in all groups(P<0.05)and was lower in the acupuncture-medication group than in the other three groups(P<0.05);all groups showed a decrease in the TCM symptom score(P<0.05),and the acupuncture-medication group was significantly lower than the other groups(P<0.05).After treatment,the blood flow velocity of the bilateral anterior cerebral artery(ACA),middle cerebral artery(MCA),and posterior cerebral artery(PCA)increased in every group(P<0.05),and the acupuncture-medication group had higher blood flow velocities compared to the other three groups(P<0.05).The acupuncture-medication group had the fewest number of complications among the four groups(P<0.05),and there was no statistical significance when comparing the adverse reactions among the groups(P>0.05).Conclusion:Compared to the separate use,the combined use of acupuncture and medication enhances the clinical efficacy,accelerates cerebral blood circulation,and boosts the recovery in treating cerebral infarction.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Pediatric urological non-Hodgkin lymphoma is relatively rare.When a single renal or ureteral tumor with multiple lymph node or bone metastases is present, it is very easy to be misdiagnosed as urinary tumor with metastasis, resulting in unnecessary radical nephrectomy. This paper reports two cases of non-Hodgkin lymphoma presenting with single urinary nodules. Case 1 was diagnosed with a 4.5cm tumor in the right kidney due to fever and fatigue. CT and PET-CT showed multiple bone destruction and lymph node metastasis. Renal biopsy was performed and ALK-positive anaplastic large cell lymphoma was diagnosed. Chemotherapy was effective for 6 months. Case 2 was diagnosed with left hydronephrosis due to intermittent low back pain for 2 weeks. Ultrasound examination revealed ureteral dilation with left hydronephrosis and low echo occupying of the lower ureter. The patient had sudden blurred vision before surgery. MRI examination revealed space occupying in the right optic nerve frame, and PET-CT found multiple bone, lymph nodes and nerve invasion. A lymph node biopsy was performed and Burkitt lymphoma was diagnosed. After 6 months of chemotherapy and radiotherapy, the tumor shrank significantly.
