Objective:To explore the effects of closed reduction elastic intramedullary nail fixation (CR-ESIN) on the rehabilitation process and joint function of children with femoral fractures.Methods:A retrospective study was conducted on 102 children with femoral fractures who underwent internal fixation surgery in our hospital from April 2024 to June 2025. Based on different surgical plans, 51 children who underwent CR-ESIN treatment were included in the CR-ESIN group, and the remaining 51 children who underwent traditional open reduction plate internal fixation (ORIF) treatment were included in the ORIF group. The treatment status, rehabilitation process, incidence of surgical complications, joint function recovery, and burden during the removal of internal fixation materials were compared between the two groups of children.Results:Under different surgical plans, the surgical time, intraoperative blood loss, postoperative hospitalization time, brace use time, and complete weight-bearing time of the CR-ESIN group were (60.29 ± 5.44) min, (50.52 ± 5.49) mL, (6.22 ± 1.34) d, (4.15 ± 1.33) weeks, and (6.81 ± 1.34) weeks, lower than the ORIF group [(76.33 ± 8.29) min, (190.48 ± 20.51) mL, (8.17 ± 1.65) d, (6.32 ± 1.48) weeks, and (7.82 ± 2.17) weeks] (t=11.552，47.076，6.552，8.322，2.828; P<0.05). The incidence of surgical complications in the CR-ESIN group was 5.88% (3/51) lower than the ORIF group 19.61% (10/51) (x2=4.320; P<0.05). The hip flexion range of motion, extension range of motion, and PODCI scores of the CR-ESIN group were (132.44 ± 22.52) °, (20.39 ± 4.47) °, and (75.14 ± 6.29) points, higher than the ORIF group [(120.28 ± 20.37) °, (17.55 ± 3.12) °, and (70.31 ± 5.36) points]. The length difference between the bilateral femurs was (1.52 ± 0.39) cm, which was lower than the ORIF group (3.08 ± 0.44) cm (t=2.860，3.721，4.174，18.948; P<0.05). The length of the surgical incision, the duration of the extraction surgery, the amount of bleeding during the extraction surgery, and the rate of re fracture in the CR-ESIN group were all lower than the ORIF group (t/x2=31.706，8.298，38.448，4.883; P<0.05).Conclusion:CR-ESIN can improve the surgical efficiency and reduce the risk of bleeding in children with femoral fractures. Compared with traditional ORIF, this procedure is beneficial for accelerating the recovery process of children, reducing the incidence of postoperative complications, promoting joint function recovery, and reducing the burden of internal fixation removal stage.

Objective:To explore the application value of dapagliflozin and its short-term cardiac function improvement effect in patients with type 2 diabetes mellitus (T2DM) combined with unstable angina (UA) after percutaneous coronary intervention (PCI). Methods: This was a single-center, randomized controlled trial. A total of 90 patients with type 2 diabetes mellitus (T2DM) complicated with unstable angina (UA) after percutaneous coronary intervention (PCI) were enrolled and randomly assigned to a dapagliflozin group (n=43) and a metformin group (n=47). Hypoglycemic agents were adjusted routinely to ensure consistent glycemic control intensity between the two groups. During treatment and at 6–12 months after treatment, left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were measured by echocardiography, and venous blood samples were collected to determine the level of N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) for the evaluation of cardiac function changes. Results: During the 6-month follow-up after PCI treatment, the N-terminal pro-brain natriuretic peptide (NT-proBNP) level in the observation group decreased significantly (P<0.01), and the left ventricular ejection fraction (LVEF) increased significantly (P<0.01).Compared with the control group, the NT-proBNP level in the observation group was notably lower (P<0.01) and also remained below that of the control group. Conclusion: For type 2 diabetes mellitus (T2DM) patients complicated with unstable angina pectoris after PCI, adjuvant treatment with dapagliflozin for 6 months can significantly improve cardiac function surrogate markers such as NT-proBNP and LVEF, with favorable safety profile.

Dengue fever is an acute infectious disease caused by the dengue virus. In recent years, it has prevailed widely in tropical and subtropical regions, posing a severe threat to public health security. Given the lack of specific antiviral drugs and high-efficiency vaccines for dengue fever, its clinical treatment is predominantly based on integrated traditional Chinese and Western medicine. The two medical systems exhibit distinct focuses and complementary advantages in the interpretation of pathogenesis and the formulation of diagnosis and treatment strategies. This paper systematically reviews the epidemiological characteristics, pathological basis, pathogenesis and current Western medical treatment status of dengue fever, and further elaborates the etiology, pathogenesis, lesion location, syndrome differentiation and treatment system, as well as research progress of traditional Chinese medicine for this disease. It aims to provide references for the optimization of clinical diagnosis and treatment and the expansion of scientific research directions on dengue fever.

      目的  探讨精子DNA碎片指数（DFI）对体外受精-胚胎移植（IVF-ET）胚胎发育及妊娠结局的影响，为优化男性生育力评估及辅助生殖治疗策略提供依据。方法  回顾性分析2023年1月—2024年1月于徐州市妇幼保健院接受IVF-ET治疗的126对不孕夫妇，根据男方DFI检测结果分为低碎片组（DFI≤15%，n=42）、临界组（15%＜DFI＜30%，n=45）和高碎片组（DFI≥30%，n=39）。比较三组患者受精相关指标、胚胎发育指标及妊娠结局指标的差异，并分析DFI与各指标的相关性。结果  低碎片组双原核率（2PN）率、优质胚胎率及囊胚形成率均高于临界组和高碎片组（P＜0.001），低碎片组1PN率、多PN率均低于临界组和高碎片组（P＜0.001）；三组种植率、临床妊娠率、早期流产率比较差异无统计学意义（P＞0.05），但高碎片组活产率低于低碎片组（P＜0.05）。相关性分析结果表明，DFI与优质胚胎率（r=-0.412，P＜0.001）、囊胚形成率（r=-0.387，P＜0.001）、活产率（r=-0.287，P=0.012）呈负相关，与早期流产率（r=0.206，P=0.059）、种植率（r=-0.215，P=0.058）、临床妊娠率（r=-0.203，P=0.072）无显著相关性。结论  精子DNA碎片指数是影响IVF-ET胚胎发育及妊娠结局的重要因素，高DFI主要通过降低胚胎发育潜能及增加流产风险导致活产率下降，临床需对高DFI患者进行干预以改善治疗结局。

       目的   基于结构方程模型（SEM）验证早产儿母亲育儿胜任感的多路径作用机制。方法  采用便利抽样法选取2024年6月—2025年6月在莆田学院附属医院分娩的早产儿母亲250例作为研究对象。采用一般资料调查表、中文版育儿胜任感量表（C-PSOC）、婴儿母亲育儿支持问卷（PSM）、角色适应问卷、简式亲职压力量表收集数据。通过单因素分析及多元线性回归分析母亲育儿胜任感的影响因素，使用AMOS软件构建结构方程模型，分析早产儿分娩后母亲育儿胜任感的作用路径。结果  250例早产儿母亲的C-PSOC得分为（61.93±6.02）分，多元线性回归分析结果显示，早产儿母亲育儿胜任感的影响因素包括产次、育儿支持、角色适应、亲职压力（均P＜0.05）。结构方程模型拟合良好（χ ² /df=1.026，GFI=0.987，AGFI=0.978，NFI=0.987，CFI=1.000，RMSEA=0.010），其中角色适应正向预测育儿胜任感（β=0.344），育儿支持（β=-0.477）与亲职压力（β=-0.283）负向预测（均P＜0.05），并且角色适应通过育儿支持、亲职压力间接提升育儿胜任感（效应值0.467）；产次经角色适应间接降低压力源影响（效应值0.529）。结论  早产儿母亲育儿胜任感受多路径机制调控，临床需针对角色适应、育儿支持及亲职压力设计级联干预策略。

       Objective  To verify the multi-pathway mechanism of parenting competence of premature infant mothers based on structural equation modeling（SEM）．Methods  A convenience sampling method was used to select 250 mothers of preterm infants who delivered in Affiliated Hospital of Putian University between June 2024 and June 2025 as the study subjects．Data was collected using a general information survey，the Chinese version of the Parenting Sence of Competence Scale（C-PSOC），the Parenting Support Questionnaire for Infant Mothers（PSM），the Role Adaptation Questionnaire，and the Simplified Parenting Stress Scale．By conducting  single factor analysis and multiple linear  regression analysis on the influencing factors of maternal parenting competence，a structural equation model was constructed using AMOS software to analyze the pathway of maternal parenting competence after premature birth．Results  The C-PSOC score of 250 mothers of premature infants was（61.93±6.02）．Multiple linear  regression analysis showed that the influencing factors of parenting competence among mothers of premature infants included parity，parenting support，role adaptation，and parental pressure（all P＜0.05）．The structural equation model fits well（2/df=1.026，GFI=0.987，AGFI=0.978，NFI=0.987，CFI=1.000，RMSEA=0.010），which  role adaptation  positively  predicted parenting competence（β=0.344），parenting support（β=-0.477）and parenting stress（β=-0.283）negatively predicted（all P＜0.05），and role adaptation indirectly enhanced parenting competence through parenting support and parenting stress（effect value 0.467）．The adaptation of roles during childbirth indirectly reduced the impact of stressors（effect value 0.529）．Conclusions  The multi-pathway mechanism of parental competence perception regulation in premature infant mothers requires the design of cascading intervention strategies targeting role adaptation，parenting support，and parental stress in clinical practice．
