ObjectiveTo evaluate whether the use of intrapartum ultrasound （IPUS） to monitor the labor process， as alternative method of traditional vaginal examination （VE）， could reduce the incidence of postpartum complications associated with vaginal delivery. MethodsA total of 360 primiparas who underwent cervical dilation balloon induction of labor （IOL） and achieved successful vaginal delivery after childbirth at the Third Affiliated Hospital of Sun Yat-sen University between January 2022 and December 2023， were included in the retrospective study with half assessed for labor progress using IPUS （n=180） and the other half using VE （n=180）. The differences in the relevant indicators of the labor process and the complications of vaginal delivery were compared between the two groups of pregnant women. ResultsThere was no significant difference in the duration of membrane rupture， the first stage of labor and the second stage of labor between the two groups. However， the number of VE in the IPUS group was significantly lower ［nulliparous： 4 （3-4） vs. 6 （5-8）， P＜0.001； multiparous： 2 （2-3） vs. 4 （3-5）， P＜0.001］. The IPUS group experienced a lower incidence of postpartum fever compared to the VE group ［1.67%（3/180） vs. 7.22%（13/180）， P=0.006］， while other complications of vaginal delivery， such as fever during labor， postpartum hemorrhage （PPH）， laceration， poor wound healing and uroschesis， were not significantly different （all P ＞ 0.05）. The logistic regression analysis confirmed that the use of IPUS served as a protective factor for postpartum fever with an OR of 0.06 ［95% CI （0.01， 0.36）； P=0.002］， while the duration of membrane rupture was a risk factor ［OR： 1.12； 95% CI （1.03， 1.22）； P = 0.011］. ConclusionsIPUS， as an alternative to traditional VE， does not affect the progress of labor. However， it can significantly reduce the frequency of VE and the incidence of postpartum fever， thereby facilitating the rapid recovery of postpartum women， which makes it clinically valuable for application.

Objective:To explore the current status and influencing factors of fatigue in patients with Cushing syndrome in China, so as to provide a basis for clinical interventions.Methods:Convenience sampling was used to select 260 inpatients with Cushing syndrome who met the inclusion and exclusion criteria in 9 ClassⅢ Grade A hospitals within the 7 geographic subregions of China from February to April 2023 for the study. General Information Questionnaire, the Chinese version of the Multidimensional Fatigue Inventory-20, Barthel Index, and Self-Rating Depression Scale were used for the survey.Results:A total of 260 questionnaires were distributed and 241 valid questionnaires were recovered, with an effective recovery rate of 92.7% (241/260). The MFI-20 score of 241 patients with Cushing syndrome was 58.00 (46.00, 64.00). 65.1% (157/241) of patients with Cushing syndrome suffered from fatigue, and 73.2% (115/157) of patients with fatigue exhibited multidimensional fatigue. Univariate analysis showed that there were statistically significant differences in fatigue scores among patients with Cushing syndrome with different cultural levels, recurrence frequency, activity of daily living, hypertension, and depression ( P<0.05). Multiple linear regression analysis showed that depression was a risk factor for fatigue in patients with Cushing syndrome, and the difference was statistically significant ( P<0.05) . Conclusions:Fatigue in patients with Cushing syndrome needs attention. Medical and nursing staff should pay close attention to the psychological status of patients with Cushing syndrome, encourage them to actively cope, alleviate their depression, in order to improve their fatigue.

Objective:To gain an in-depth understanding of the career development of male nurses in China, analyze trends, challenges, and opportunities, and provide a basis for policy-making, talent cultivation, and professional development in the nursing field.Methods:A descriptive qualitative research method was adopted. From March 29th to July 30th, 2023, the heads of the male nurses working groups of nursing associations in 26 regions of China were selected by purposive sampling method for semi-structured interviews. Content analysis was used to analyze the data.Results:The current situation of the career development of male nurses in China could be summarized into the following three themes. (1) Current situation: the organizational structure of provincial-level male nurses work was basically complete, but there were obvious differences at the grassroots level; the work was carried out in various forms, and diverse models developed in coordination; (2) Trends: there were obvious stratifications in professional ideology and professional abilities of male nurses among different regions and different-level medical institutions; the gender dividend was gradually decreasing, and male nurses should give play to their advantages in logical thinking ability; (3) Prospects: early intervention was needed to enhance professional identity and organizational support; male nurses should be trained in various aspects through multiple forms such as counterpart assistance, expert databases or online academic forums; interdisciplinary development might be the key to stimulating internal driving force.Conclusions:Significant progress has been made in the career development of male nurses in China, but there are still challenges and issues to address. Further improvements in related policies, enhancement of social recognition and professional status, and increased investment and support in research and education are needed to promote the sustained development of male nursing careers.

Objective:To explore the latent profile characteristics of cancer-related fatigue (CRF) in breast cancer patients during the rehabilitation phase and to analyze the influencing factors of different latent profiles.Methods:A convenience sampling method was used to recruit 190 breast cancer patients in the rehabilitation phase from the follow-up cohort at Peking Union Medical College Hospital between March and May 2024. Data was collected using a general information questionnaire, the Cancer Fatigue Scale, the Self-Rating Anxiety Scale, the Self-Rating Depression Scale, the Pittsburgh Sleep Quality Index and the Visual Analogue Scale. Logistic regression analysis was conducted to identify the influencing factors of CRF latent profiles. A total of 190 questionnaires were distributed, and 183 valid responses were collected, yielding an effective response rate of 96.32% (183/190) .Results:Three latent profiles of CRF were identified: mild fatigue, moderate fatigue, and severe fatigue. Menopausal status, depressive symptoms, and pain scores were significant influencing factors of the CRF latent profiles ( P<0.05) . Conclusions:Cancer-related fatigue in breast cancer patients during the rehabilitation phase exhibits distinct latent profile characteristics. Early identification of profile types and associated influencing factors may provide a scientific basis for healthcare professionals to develop targeted clinical interventions to help patients alleviate fatigue.

ObjectiveTo investigate the perceived experience and acceptance of intrapartum ultrasound （IPUS） as a novel method for labor progress assessment among pregnant women. MethodsFrom February 2023 to December 2024， a total of 180 pregnant women admitted to the Labor Ward of Lingnan Hospital， the Third Affiliated Hospital of Sun Yat-sen University， who were planned for vaginal trial of labor ， were accessed for labor progress using IPUS and vaginal examination （VE） after the onset of labor and prior to the initiation n of labor analgesia. A self-designed questionnaire was used to investigate the women's perceived experiences with both examination methods and their acceptance of IPUS. The pain intensity associated with the examinations was evaluated using the visual analogue pain scale （VAS）. Differences in the women's experiences and pain intensity between the two labor progress assessment methods were compared. ResultsThe acceptance rate of IPUS was 96.67% （174/180）， with the remaining 6 cases undecided. Over 60% of the pregnant women reported IPUS assessment as comfortable and none of them felt discomfort， whereas 32.8% felt uncomfortable with VE （χ²=196.02， P＜0.001）. Nearly two-thirds of the pregnant women believed that VE would cause psychological distress， while none reported such effect with IPUS （χ²=261.52， P＜0.001）. Approximately 77.78% （140/180） of the pregnant women believed that IPUS could reduce their fear of vaginal delivery and enhance their confidence if it replaced VE. The VAS score for IPUS ［0 （0， 2）］ was significantly lower than that for VE ［4 （4， 6）］ （Z=-14.62， P＜0.001）. Further stratified analysis showed that over 90% （164/180） of the pregnant women found IPUS painless， with no moderate or severe pain reported， compared to 43.33% （78/180） experienced moderate or severe pain with VE （P＜0.001）. ConclusionAs a novel approach for labor progress assessment， IPUS not only alleviates the pain and discomfort associated with traditional VE and reduces the fear of childbirth but also enhances women's confidence in delivery， thereby achieving a high level of acceptance among parturient women in China.

OBJECTIVE To evaluate the efficacy and safety of apatinib combined with PD-1/PD-L1 inhibitors in the treatment of malignant solid tumors. METHODS Randomized controlled trials （RCTs） on apatinib combined with PD-1/PD-L1 inhibitors （combination group） versus monotherapy （apatinib or PD-1/PD-L1）combined with （or） chemotherapy/other treatments （control group） in the treatment of malignant solid tumors were collected from PubMed， Web of Science， Embase， Cochrane Library， CNKI， VIP， Wanfang Data and China Biomedical Literature Database. The search time limit was from the establishment of the databases to May 2025. After literature screening， data extraction and literature quality evaluation， meta-analysis was performed using RevMan 5.3 and Stata 14.0. RESULTS A total of 28 RCTs involving 2 974 patients were included. The objective response rate [RR＝1.639， 95%CI（1.452，1.851）， P＜0.000 01]， disease control rate [RR＝1.284， 95%CI（1.178，1.399）， P＜0.000 01] and CD3+， CD4+， CD4+/CD8+ as well as the incidence of ADR such as hypertension， fatigue， proteinuria， thrombocytopenia were significantly higher in the combination group than control group （P＜0.05 or P＜0.000 01）. The progressive disease rate [RR＝ 0.497， 95%CI（0.437， 0.566）， P＜0.000 01] and serum tumor + marker levels and CD8 were significantly lower in the combination group than control group （P＜0.05 or P＜0.000 01）. Subgroup analysis results of different types of tumors showed that the objective response rate and disease control rate were significantly higher in the combination group than control group （P＜0.05）. The results of sensitivity analysis showed that the stability of this study was good. The results of publication bias analysis showed that there was a high possibility of publication bias in this study. CONCLUSIONS Apatinib combined with PD-1/ PD-L1 inhibitors has a significant efficacy in the treatment of different types of tumors， but attention should be paid to the occurrence of hypertension， fatigue， proteinuria and thrombocytopenia.

Human carboxylesterase 2A (hCES2A) plays pivotal roles in prodrug activation and hydrolytic metabolism of ester-bearing chemicals. Targeted inhibition of intestinal hCES2A represents a feasible strategy to mitigate irinotecan-triggered gut toxicity (ITGT), but the orally active, selective, and efficacious hCES2A inhibitors are rarely reported. Here, a novel drug-like hCES2A inhibitor was developed via three rounds of structure-based drug design (SBDD) and structural optimization. Initially, donepezil was identified as a moderate hCES2A inhibitor from 2000 US Food and Drug Administration (FDA)-approved drugs. Following two rounds of SBDD and structural optimization, a donepezil derivative (B7) was identified as a strong reversible hCES2A inhibitor. Subsequently, nine B7 carbamates were rationally designed, synthesized and biologically assayed. Among all synthesized carbamates, C3 showed the most potent time-dependent inhibition on hCES2A (IC₅₀ = 0.56 nmol/L), excellent specificity and favorable drug-like properties. C3 could covalently modify the catalytic serine of hCES2A with high selectivity, while this agent also showed favorable safety profiles, high intestinal exposure, and impressive effects for ameliorating ITGT in both human intestinal organoids and tumor-bearing mice. Collectively, this study showcases a rational strategy for developing drug-like and serine-targeting covalent inhibitors against target serine hydrolase(s), while C3 emerges as a promising orally active drug candidate for ameliorating ITGT.
