Intracranial atherosclerotic stenosis (ICAS) is a common cause of ischemic stroke. The evaluation of its structure and function is of great significance for formulating clinical intervention strategies. The indications for endovascular treatment of ICAS lesions in the past were mainly based on the degree of luminal stenosis showed by cerebral angiography, which had certain limitations. The translesional pressure ratio (PR), as an important indicator for functional assessment after arterial stenosis, has gradually received attention in the evaluation of ICAS lesions in recent years. This article reviews the evaluation methods and clinical significance of PR in ICAS lesions.

Objective This qualitative study aimed to explore the home-based exercise rehabilitation experiences of elderly patients after hip fracture surgery,in order to provide references for exercise intervention during rehabili-tation period.Methods Objective sampling method was used to select 13 elderly hip fracture patients who were hospitalized in the joint surgery department of a tertiary A hospital in Beijing from August 2023 to June 2024 as the research subjects.Semi-structured interviews were conducted,and the interview data were sorted and analyzed by content analysis method.Results The home-based exercise rehabilitation experience of elderly patients after hip fracture surgery can be summarized into 3 themes,including multi-dimensional self-empowerment,use of dynamic personalized skills,full cycle balance reconstruction.Conclusion Patients after hip fracture surgery have rich expe-riences in home exercise rehabilitation,including self-empowerment,exercise skills and balance reconstruction.Nurs-ing staff should strengthen long-term follow-up,according to the real experience and feeling of the patient's home exercise rehabilitation in the whole cycle,actively assist the patients to self-empower,and use various exercise skills to constantly rebuild balance to achieve rehabilitation.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is characterized by congenital vaginal hypoplasia and primordial uterus caused by Müllerian anomalies. Case reports concerning adenomyosis associated with MRKH syndrome are limited, and the formation and intervention of adenomyosis without endometrium are unclear. Here, we present the case of a patient with MRKH syndrome complicated with adenomyosis without endometrium, a hypoechoic solid mass next to the right ovary. According to the intraoperative observation and histopathological examination findings, the mass were diagnosed as adenomyosis of the primordial uterus. Moreover, our report provides insights about its mechanism of occurrence and interventions in MRKH syndrome combined with adenomyosis without endometrium.

Objective:To construct a narrative nursing intervention plan for post-traumatic growth (PTG) in breast cancer patients and evaluate its effectiveness.Methods:Based on PTG model and the core principles of narrative nursing techniques, an intervention plan was constructed, consisting of three themes. The first unit, "Me and Them, " used externalization techniques to construct deliberate rumination. The second unit, "What Kind of Person Am I, " used deconstruction and rewriting techniques to promote effective disease coping. The third unit, "We Are Together, " applied external witnesses and therapeutic documentation techniques to enhance social support and consolidate growth. Individualized face-to-face interventions were implemented, with each unit receiving one session lasting 1 to 1.5 hours, for a total of three sessions. Using purposive sampling, 42 breast cancer patients hospitalized in the Daytime Ward of Beijing Tiantan Hospital from July to October 2024 were selected. These patients were divided into an intervention group, which received the narrative nursing intervention plan, and a control group, which received routine nursing care, with 21 patients in each group. The Post-Traumatic Growth Inventory (PTGI) and the Chinese version of the Event-Related Rumination Inventory (C-ERRI) were used to assess the patients before and after the intervention.Results:After the intervention, the intervention group showed significantly higher scores on the PTGI and deliberate rumination in the C-ERRI compared to the control group, while the intervention group had significantly lower scores on intrusive rumination in the C-ERRI compared to the control group. The differences were statistically significant ( P<0.05) . Conclusions:The narrative nursing intervention plan for PTG in breast cancer patients constructed in this study is scientifically sound and feasible. It can help breast cancer patients enhance their PTG levels and develop deliberate rumination.

Objective:To analyze the predictive factors associated with late-onset sepsis(LOS) in very low birth weight infants,and to develop a risk prediction score scale applicable to these infants three days postnatal.This will provide valuable insights for early diagnosis and timely intervention.Methods:Very low birth weight infants admitted to the Children's Hospital of Fudan University from January 1,2022,to June 30,2024,were selected as research subjects.These infants were categorized into two groups:the LOS group and the non-LOS group,based on whether they developed LOS.LASSO regression analysis,alongside univariate and multivariate regression analyses,was employed to identify predictive factors for LOS in this population.A Logistic model was constructed using the optimal combination of predictive variables,and a risk assessment scale was subsequently developed.The prediction performance of the model was evaluated using the Hosmer-Lemeshow chi-square test and the receiver operating characteristic curve.Results:A total of 444 cases of very low birth weight infants were included,of which 185 had LOS and 259 did not.After screening the variables,seven independent factors were included into the model:birth weight,gestational age,tracheal intubation,abnormal skin color,abdominal distension,elevated C-reactive protein levels,and right hand perfusion index.A predictive scoring scale was developed based on the regression coefficients of each variable,with corresponding risk scores assigned as follows:1,4,3,2,1,1,and 2; a score of ≥3.5 indicated high-risk groups.The Hosmer-Lemeshow test results demonstrated that χ2 = 7.602( P = 0.473).The area under the receiver operating characteristic curve was 0.792 ( P<0.001),with a sensitivity of 73.5% and specificity of 71.0%. Conclusion:The risk score scale developed in this study exhibits significant predictive capability,providing valuable insights for clinical medical personnel to assess the risk of LOS in very low birth weight infants during the early postnatal period.

Objective To compare the clinical outcomes of the clomiphene citrate(CC)dual stimulation protocol and the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved in POSEIDON patients with low expected prognosis.Methods The clinical data from patients who underwent in vitro fertilization(IVF)or intracytoplasmic sperm injection(ICSI)at the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from May 2016 to December 2023 were analyzed retrospectively.According to the POSEI-DON criteria,including POSEIDON group 3 and group 4,which were treated with the CC dual stimulation protocol(the CC group)and the luteal-phase ovarian stimulation protocol after the natural cycle oocytes retrieval(the natural cycle group).The basic data and clinical outcomes of the two ovulation protocols were analyzed,and the main observations included the number of oocytes retrieved,the cumulative clinical pregnancy rate and the cumulative live birth rate,and explored the impact of ovulation promotion regimens on clinical outcomes through binary logis-tic regression.Results On the whole,there was no significant difference in the total number of oocytes retrieved,cumulative clinical pregnancy rate and live birth rate between the CC group and the natural cycle group(all P>0.05),And in POSEIDON group 4,the numbers of oocytes retrieved in the follicular phase of the CC group were higher than those in the natural cycle group,whereas the number of oocytes retrieved in the luteal phase of natural cycle group were higher,and the difference was statistically significant(P<0.05).After logistic regression analysis,the ovulation stimulation protocols did not affect the cumulative clinical pregnancy rate and live birth rate of POSEI-DON 3 and 4 group(P>0.05).Conclusions For the POSEIDON patients with a low expected prognosis,the clinical effectiveness of the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved is not inferior to that of the CC dual stimulation protocol.In POSEIDON group 4,on the premise that the AMH levels of patients in the natural cycle group were lower than those in the CC group,who underwent natural cycle ovulation followed by luteal phase induction achieved similar clinical outcomes to those of the CC dual stimulation protocol group.Therefore,the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved should be more clinically recommended for POSEIDON group 4 patients.
