Bone morphogenetic proteins (BMPs) are multifunctional growth factors of the transforming growth factor β (TGF-β) superfamily. They regulate steroid secretion from mammalian granulosa cells, promote granulosa cell survival and proliferation, and inhibit follicular atresia, luteinization, and granulosa cell apoptosis, thereby promoting the development and maturation of mammalian follicles. At the same time, BMPs play an important role in embryonic morphogenesis, induction of uterine receptivity, and blastocyst attachment. This paper describes the effects of BMPs on mammalian follicular and embryonic development and the roles of BMPs in female reproduction, focusing on the process in which BMPs promote follicular maturation by regulating steroid secretion from granulosa cells during mammalian oocyte maturation. This review aims to provide a reference for further research on mammalian oocyte culture and improvement of reproductive efficiency in female animals.

Objective To investigate the status and influencing factors of type 2 diabetes mellitus(T2DM)patients' fear of complications,and to provide a reference for formulating targeted intervention measures.Methods From April to November 2024,370 patients with T2DM in 2 tertiary general hospitals in Daqing City were selected by convenience sampling method.General data questionnaire,Fear of Complications Questionnaire,Self-Perceived Burden Scale,Psychological Capital Questionnaire,Mishel Uncertainty in Illness Scale and Family Apgar Index Questionnaire were used for investigation.Univariate analysis and binary Logistic regression were performed to analyze the influencing factors.Results A total of 364 valid questionnaires were collected,with an effective recovery rate of 98.38％.The score of Fear of Complications Questionnaire was(23.47±7.47),and the incidence of fear of complications was 22.25％.Logistic regression analysis showed that medical payment methods,the number of complications,positive psychological capital and family care were the influencing factors of FoC in T2DM patients.Conclusion The fear of complications in T2DM patients is at a moderate level.Nursing staff should pay attention to the early assessment of patients' fear of complications,promptly identify and take effective measures to reduce the level of patients' fear of complications,improve their quality of life.

Objective:To investigate the status quo and influencing factors of humanistic concern among nursing undergraduates, and to explore the educational path of improving humanistic concern.Methods:A total of 345 nursing undergraduates from Xiangya School of Nursing of Central South University were investigated using a questionnaire of general demographic data, the Caring Ability Inventory, and the Self-directed Learning Instrument. The SPSS 26.0 statistical software was used for data analysis. The humanistic caring ability scores of nursing undergraduates with different characteristics were compared by the independent sample t-test and analysis of variance, and the pairwise comparison was conducted by the least significant difference t-test. All dimensions and total scores of humanistic caring ability and self-directed learning ability failed to meet normal distribution, and the correlation between them was determined by Spearman correlation analysis. Results:The humanistic caring ability score of nursing undergraduates was (169.52±10.62). The correlation analysis showed that the humanistic caring ability of nursing undergraduates was positively correlated with their self-directed learning ability ( r=0.426, P<0.001). The stepwise regression analysis showed that interpersonal communication ability, learning motivation, grades, genders, and class leader experience were influencing factors of humanistic caring ability of nursing undergraduates. Conclusions:Nursing undergraduates should improve their humanistic caring ability, whose score is lower than that in the existing research (175.70±18.74). In humanistic education, nursing educators should pay attention to individualized development needs of nursing undergraduates with different grades and genders, set students with class leader experience as a good example, and effectively improve the humanistic caring ability of nursing undergraduates by stimulating learning motivation and strengthening interpersonal communication.

Objective:To investigate functional outcomes and condition-specific quality-of-life (CSQoL) after intersphincteric resection (ISR) in patients with low rectal cancer using traditional and exploratory questionnaires.Methods:A prospective observational study was conducted in the Characteristic Medical Center of the People′s Liberation Army Rocket Force. Patients with low rectal cancer who underwent ISR with ileostomy reversal from May 2020 to April 2023 were enrolled. An electronic self-assessment survey was sent to enrolled patients at 3 to 6, 12, and 24 to 36 months after reversal, and differences in functional and CSQoL results between the 3 groups were analyzed with generalized estimation equations. Functional outcomes were determined by the Wexner incontinence score (WIS) and the low anterior resection syndrome (LARS) score. In line with the five frequency responses ranging from never (score 0) to always (score 4) defined by the WIS, an exploratory survey was used to measure the severity of 16 LARS-specific variables confirmed by the latest international Delphi consensus. Furthermore, CSQoL was evaluated using the fecal incontinence quality-of-life scale (FIQL) and the visual analog scale (VAS).Results:A total of 90 patients were enrolled in the study. There were 64 males and 26 females, aged (58.6±10.4) years (range: 28 to 79 years). The median distance from the distal tumor margin to the anal verge( M(IQR)) was 3.0 (1.5) cm (range: 1.0 to 5.0 cm). There were 55 patients who completed the questionnaires at 3 to 6 months, 59 patients at 12 months, and 40 patients at 24 to 36 months of follow-up, respectively. The summary score of FIQL and VAS improved significantly after reversal (2.33±0.69 vs. 2.40±0.66 vs. 2.79±0.76, χ2=11.703, P=0.003; 5.31±1.65 vs. 5.61±1.90 vs. 6.58±1.92, χ2=12.781, P=0.002), but the differences in the WIS and LARS score did not reach statistical significance (both P>0.05). The survey responses for the LARS-specific variables indicated that “emptying difficulties” and “dissatisfaction with the bowels” were the most frequent symptom and consequence after ISR, respectively. The exploratory severity score for LARS improved significantly among the 3 time periods(34 (14) vs. 31 (13) vs. 23 (17), χ2=13.952, P=0.001). Furthermore, the FIQL summary score was strongly correlated with the LARS severity score ( r s=-0.72, P<0.01). Conclusions:Although a high prevalence of LARS may persist for years, patients reported an improvement in CSQoL and functional outcomes after ISR. The highest priorities recommended by the international consensus might provide better assessments the severity of LARS.
