【Objective】 To investigate the prevalence and influencing factors of feeding difficulties in preterm infants at weaning and self-feeding transition stage, so as to provide a scientific basis for the management of feeding preterm infants. 【Methods】 Preterm infants at corrected age of 6 - 24 months were recruited from the Department of Child Health of five maternal and child health hospital of Chengdu from April to May 2021, and were surveyed by using the Chinese Version of the Montreal Children Hospital Feeding Scale (MCF-FS) and the self-designed questionnaire on the influencing factors of feeding difficulties. Then the status quo of feeding difficulties and its influencing factors were analyzed. 【Results】 The prevalence rate of feeding difficulties in 231 preterm infants was 32%. Among them, the prevalence rate of mild, moderate and severe feeding difficulties was 15.2%, 7.8% and 9.1%, respectively. Binary Logistic stepwise regression analysis indicated that food allergy (OR=4.253, 95%CI: 1.430 - 12.649), anxious mood of caregivers (OR=6.064, 95%CI: 2.998 - 12.268), tease or chase during eating(OR=2.873, 95%CI: 1.382 - 5.970), recreational activities at eating (OR=2.328, 95%CI: 1.115 - 4.860), and forced feeding (OR=2.772, 95%CI: 1.239 - 6.198) were positively associated with feeding difficulty of preterm infants(P<0.05). 【Conclusion】 Feeding difficulties in the weaning and self-feeding transition period of preterm infants are prevalent, so the guidance should focus on premature infants with food allergy, anxious caregivers and improper feeding behaviors, and appropriate interventions should be taken to promote scientific feeding.

Food neophobia is one of the distinctive feeding disorders in children. It affects children′s physical growth and neurological development, resulting in negative impacts on their eating behaviors and habits. This review elucidates the concept and origin of food neophobia, and summarizes the prevalence, associated factors and effective interventions according to previous literature, in order to provide suggestions and guidance for the prevention and early intervention of children with food neophobia.

Objective:To evaluate the efficacy and safety of 308-nm excimer lamp and 308-nm excimer laser in the treatment of pediatric vitiligo.Methods:Clinical data were collected from children with stable vitiligo who received targeted phototherapy at the Department of Dermatology of Xijing Hospital from 2010 to 2015, and retrospectively analyzed. The patients were treated with either 308-nm excimer laser or 308-nm excimer lamp, and all were given topical drugs. The treatment lasted for at least 3 months, and follow-up for at least 6 months. The severity of vitiligo was assessed using the Vitiligo Area and Severity Index (VASI) score. The efficacy was evaluated after 3 months of treatment, and at least a 50% reduction in the VASI score (VASI50) was defined as "effectiveness". A logistic regression model was constructed using treatment efficacy as the dependent variable to screen factors related to the treatment outcome. The Wilcoxon signed-rank test was used to compare skewed data before and after treatment. Adverse reactions during treatment were recorded to evaluate the safety of targeted phototherapy.Results:A total of 194 children with stable vitiligo were included, comprising 103 males (53.1%) and 91 females (46.9%), with the age being 6 to 14 (10.2 ± 2.3) years. Among them, 138 (71.1%) received 308-nm excimer laser therapy, while 56 (28.9%) received 308-nm excimer lamp therapy. The VASI score ( M [ Q1, Q3]) was 0.12 (0.05, 0.40) at the baseline, significantly decreased to 0.06 (0.02, 0.19) after 3 months of treatment ( Z = 12.02, P < 0.001). After 3 months of treatment, 52 patients achieved VASI50, and 30 achieved VASI75, resulting in an overall response rate of 42.3% (82/194). Specifically, in the 308-nm excimer laser group, 38 patients achieved VASI50 and 26 achieved VASI75, with a response rate of 46.4% (64/138) ; in the 308-nm excimer lamp group, 14 patients achieved VASI50 and 4 achieved VASI75, yielding a response rate of 32.1% (18/56). Univariate logistic regression analysis indicated that lesions located on the head and neck or the trunk were more prone to repigmentation compared with those on the limbs ( OR = 3.56, 95% CI: 1.15 - 11.02, P = 0.027; OR = 6.58, 95% CI: 1.81 - 23.96, P = 0.004, respectively) ; additionally, facial lesions around the eyes were more prone to repigmentation compared with lesions on other facial areas ( OR = 4.58, 95% CI: 1.10 - 19.11, P = 0.037), and hair involvement in vitiligo lesions on the head and neck made repigmentation less likely to occur compared with lesions without hair involvement ( OR = 0.31, 95% CI: 0.13 - 0.75, P = 0.010). Multivariate logistic regression analysis revealed that the periorbital region was the most favorable site for repigmentation among facial areas ( OR = 5.37, 95% CI: 1.18 - 24.34, P = 0.029), and hair involvement in vitiligo lesions on the head and neck was an independent risk factor for phototherapy-induced repigmentation ( OR = 0.28, 95% CI: 0.08 - 0.96, P = 0.042). Among the 194 patients treated with targeted phototherapy for 3 months, 33 experienced short-term treatment-related adverse reactions, including erythema, blisters, desquamation, itching, and pain; most adverse reactions were mild, and no severe adverse reactions were observed. Conclusion:Targeted phototherapy using 308-nm excimer laser or 308-nm excimer lamp was safe and effective for the treatment of pediatric vitiligo.

Objective To investigate the effects of knowledge-attitude-practice(KAP)model based nursing interventions on positional care in patients after vitrectomy combined with intraocular filling.Methods A total of 62 patients who underwent vitrectomy combined with intraocular silicone filling,between February 2022 and November 2023,in the Department of Ophthalmology of a Grade ⅢA hospital in Tongling were selected as the study subjects.The patients were randomly divided into a control group(n=32)and an intervention group(n=32).The control group received routine nursing care,while the intervention group received KAP-model based nursing care.The two groups were compared in terms of the time of positional maintenance,the average time per day for maintaining a head-down face-down position in the first 3 days after surgery,general comfort questionnaire(GCQ),postural compliance,numerical rating scale(NRS)for pains,self-rating anxiety scale(SAS)and incidence of postoperative complications.Results In comparison with the control group,the intervention group had a longer positional maintenance time and longer average time per day for maintaining a head-down face-down position in the first 3 days after surgery(13.25±1.25 vs 15.86±1.36,20.87±1.04 vs 17.56±1.29,both P<0.001).The overall postural compliance rate in the intervention group was significantly higher(96.88％vs 76.67％,P<0.001).GCQ scores of the intervention group were higher(87.96±5.15 vs 70.24±4.89,P<0.001).NRS scores in the intervention group were significantly lower(2.41±0.26 vs 3.34±0.34,P<0.001).SAS scores in the intervention group were significantly lower(37.26±4.21 vs 44.37±4.71,P<0.001).The total incidence of postoperative complications in the intervention group was lower(3.12％vs 23.33％,P<0.05).Conclusion After vitrectomy combined with intraocular silicone filling,the implementation KAP-model based nursing care interventions prolongs the time of positional maintenance in the patients,improves positional comfort and compliance,reduces pains and relieve anxiety,as well as reduces the incidence of postoperative complications.

【Objective:】 The co-word analysis method was used to analyze narrative medical literature studied in China in the past 10 years to explore the research status in this field and lay a foundation for further research. 【Methods:】 Using "narrative medicine" as the theme term, with the limited time interval of 2013—2022 to retrieve for relevant literature in CNKI, Wanfang, and VIP databases, and include literature that meets the research standards. Bicomb2 was used to perform keyword statistics and analysis on the downloaded literature. Ucinet6.0 and Netdraw were used to draw co-occurrence analysis graphs to visualize the co-occurrence relationship between high-frequency keywords. 【Results:】 A total of 565 papers were included and 31 high-frequency keywords were extracted. The co-occurrence relationship diagrams showed that the current research hotspots of narrative medicine in China include traditional Chinese medicine, nursing, general practice, evidence-based medicine, medical ethics, hospice care, chronic diseases, cancer and other popular disciplines and diseases. Most of them were about enhancing the empathy and humanistic caring ability of medical personnel and improving doctor-patient communication to improve the doctor-patient relationship, as well as doing well in medical humanities education and cultivating narrative ability through parallel medical records and reflective writing. The research on gerontology, improving the professional identity of medical staff, integrating literature and medicine, and the impact on patients were relatively few. 【Conclusion:】 At present, narrative medicine in China has achieved many achievements in fields such as nursing, traditional Chinese medicine, general practice medicine, chronic diseases, cancer, medical humanities education, and improving doctor-patient relationships. In the future, in-depth exploration can be conducted from the use of narrative medicine in multi-disciplinary and disease fields, trying different training methods, and synchronous cultivation of teachers and students, so as to build a more comprehensive narrative medicine system.

Medical adhesive-related skin injury (MARSI) is a kind of skin damage which is closely related to the quality of nursing care, and have been attached more and more attention by foreign nursing staff in recent years, however, our clinical nursing staff had limited awareness and knowledge on MARSI and lack of attention. In this paper, the relevant literature at home and abroad was collected and summarized from the perspective of preventive measures, in order to improve the recognition and attention of Chinese nurses on MARSI, promote the rational use of medical adhesive, and prevent the occurrence of MARSI.

Objective To elucidate whether and how injection site diversity influences on the sodium hyaluronate (HA) distribution on cartilage surface of the knee joint.Methods From September 2014 to December 2014, 32 human cadaveric knees were sorted from small to large based on femoral condyle width (FCW) and divided into group Ⅰ (n=16, odd number, the patella medial approach) and group Ⅱ (n=16, even number, injected through the medial joint line approach).Knees of both groups were interfused with a 5％ (mg: ml) methylene blue tracer.Each specimen was then simulated a 5°-45° alternating walking for 2 h in the Electro Force platform.Afterwards, all the knee cavities were cut open to examine the range of HA distribution.Based on the eight-zoning classification law for the knee cartilage surface, the coverage area of HA in each zone was scored and the characteristics of HA distribution was depicted, as well as HA zonal distribution diversity between groups were statistically analyzed.Results HA of both patella medial and medial joint line subgroups showed analogical distribution in all zones except the lateral tibial plateau at the time of FCW ≤ 7.0 cm.However, HA coverage through the patella medial approach showed significantly higher distribution scores in the patella zone and the femoral trochlear zone, but significant lower distribution scores in the antero-lateral/postero-lateral femoral condyle, the medial posterior femoral condyle zone and the lateral tibial plateau zone compared with medial joint line approach at the time of FCW ＞ 7.0 cm.Conclusion When delivered through different injection approaches, HA showed analogical distribution characteristics in most zones of the knee cavity in population with a small bodily shape (FCW ≤ 7.0cm), but significant diverse distribution characteristics in population with a big bodily shape (FCW ＞7.0 cm).When FCW ＞ 7.0cm, HA injected through the medial-patellar approach tended to be distributed mainly over the patella-femoral articulation and the anterior knee cavity, while HA injected through the joint line approach tended to be distributed mainly over the tibio-femoral articulation and the posterior knee cavity.
