Microtubulin disease，which is rare in prenatal settings，is characterized by severe brain developmental abnormalities due to mutations in the microtuberin gene.In this article，a patient diagnosed with TUBB3-related microtubule proteinopathy during prenatal testing was reported，serving as a reference for prenatal physicians. A 33-year-old pregnant woman，who was 23 +5 weeks pregnant，visited to Peking University First Hospital Ningxia Women and Children's Hospital. During a prenatal ultrasound examination，it was discovered that the fetal brain midline was curved，the septum pellucida was twisted，the left lateral fissure had an oblique platform shape，the left lateral ventricle was enlarged，and there were left thoracic cystadenoma and right ventricular hyperechoic plaques. Whole exome sequencing was performed and revealed a mutation in the TUBB3 gene. The pregnancy was terminated at 26 +6 weeks of gestation. Prenatal ultrasound can detect some signs of microtubule protein disease，and genetic testing is recommended for prenatal diagnosis to comprehensively assess the prognosis of the fetus.

Objective:To explore the mediating role of coping strategies in the relationship between disease uncertainty and post-discharge coping difficulties in mothers of preterm infants.Methods:A convenience sampling method was used to select 255 mothers of preterm infants from Shandong Provincial Hospital Affiliated to Shandong First Medical University, Linyi People 's Hospital, Weifang Maternal and Child Health Hospital, Maternal and Child Care Center of Dezhou, Dongying People 's Hospital between March and May 2023. General information surveys, the Parents ' Perception of Uncertainty Scale, the Simple Coping Style Questionnaire, and Post-Discharge Coping Difficulty Scale-Parent Form were administered on the day of discharge and 3 weeks post-discharge. Structural equation modeling was constructed using AMOS 23.0 software, and the mediating effect was tested using the Bootstrap method. Results:The disease uncertainty score for the 255 mothers of preterm infants was 66.00 (53.00, 77.00), the active coping score was 23.00 (17.00, 27.00), the passive coping score was 10.00 (7.00, 13.00), and the post-discharge coping difficulties score was 42.00 (26.00, 55.00). Mediating effect analysis showed that active and passive coping partially mediated the relationship between disease uncertainty and post-discharge coping difficulties, with mediating effects of 18.73% and 17.06%, respectively.Conclusions:Disease uncertainty can indirectly affect post-discharge coping difficulties through active and passive coping strategies. Healthcare providers should assist mothers of preterm infants in appropriately managing disease uncertainty and actively coping with challenges.

Objective:To explore the mediating role of positive coping style between social support and post-discharge coping difficulty among mothers of premature infants, so as to provide guidance for medical staff to deeply understand and improve the post-discharge coping difficulty of mothers.Methods:A convenience sampling method was employed to select 310 mothers of premature infants from the neonatal intensive care units of five tertiary level A hospitals in Shandong Province from March to June 2023 as the study population. A cross-sectional survey was conducted using the general information questionnaire, the Social Support Rating Scale, the Simple Coping Style Questionnaire, and the Post-Discharge Coping Difficulty Scale-Parent Form.Results:A total of 280 valid questionnaires were returned, among which the age of mothers was (32.70 ± 5.08) years. The score of social support, positive coping style and post-discharge coping difficulty in mothers of preterm infants was (42.59 ± 7.40), (23.06 ± 6.75) and (3.64 ± 1.74) points respectively. Social support was positively associated with positive coping style ( r=0.404, P<0.01), social support and positive coping style were negatively associated with post-discharge coping difficulty ( r=-0.368, -0.369, both P<0.01). Positive coping style partially mediated the relationship between social support and post-discharge coping difficulty, which accounted for 31.11% of the total effect. Conclusions:Social support can affect post-discharge coping difficulty of mothers of premature infants through positive coping style. Medical staff should pay attention to the enhancement of social support and the cultivation of positive coping style of mothers of premature infants, and take targeted measures to reduce the post-discharge coping difficulty.

Objective:To explore the mediating role of illness perception in the relationship between fear of disease progression and sleep quality in patients with ovarian cancer during chemotherapy, and to provide a theoretical basis for improving sleep quality in patients with ovarian cancer during chemotherapy.Methods:From January to August 2022, 300 patients with ovarian cancer undergoing chemotherapy in Shandong First Medical University Affiliated Provincial Hospital, Qilu Hospital of Shandong University, Shandong Cancer Hospital were included by convenient sampling. A cross-sectional questionnaire survey included the Chinese version of the Fear of Progression Questionnaire Short Form for cancer patients, the Brief Illness Perception Questionnaire, and the Pittsburgh Sleep Quality Index. Bivariate factor analysis, Spearman correlation analysis, and the Bootstrap confidence interval evaluation method were used.Results:A total of 287 valid questionnaires were collected. The scores of fear disease progression, illness perception, and sleep quality were 30.00 (22.00, 36.00), 37.00 (32.00, 44.00), and 6.00 (3.00, 11.00), respectively. Sleep quality was positively correlated with fear disease progression ( r=0.250, P<0.001) and illness perception ( r=0.326, P<0.001). Illness perception played a partial mediating role in the relationship between fear of disease progression and sleep quality, accounting for 41.4% of the total effect. Conclusions:Ovarian cancer patients during chemotherapy reported poor sleep quality. In clinical practice, health care providers including nurses can take interventions aimed at reducing fear of disease and improving illness perception level to improve the sleep quality of ovarian cancer patients during chemotherapy.

Objective : To study the correlation between cerebral white matter structure with cognitive function and blood biochemical indexes in patients with end stage renal disease (ESRD) . Methods : The diffusion tensor imaging (DTI) data of 64 ESRD patients and 47 age and sex matched healthy people were collected. Tract⁃based spatial statistics (TBSS) and XTRACT analysis methods were used to compare the differences in diffusion parameters between the two groups. Pearson correlation analysis was used to detect the correlation between various diffusion parameters and blood biochemical indexes and cognitive related scales. Results : The values of FA in the ESRD group generally decreased (P < 0. 05) . The values of MD, AD and RD obviously increased (P < 0. 05) . The scores of mini mental state examination (MMSE) and Montreal cognitive assessment (MoCA) decreased (P < 0. 01), while that of trail making test A part (TMT⁃A) increased (P < 0. 05) . In the ESRD group, the values of FA in the right anterior thalamic radiation, optic radiation, acoustic radiation, and cingulum were negatively correlated with the levels of creatinine and urea nitrogen, and positively correlated with MoCA′s scores, and the values of MD and RD of these tracts were positively correlated with the concentration of urea. The values of FA in optic radiation, acoustic radiation and left temporal of cingulum were negatively correlated with the scores of TMT⁃A. The values of FA in the vertical occipital fasciculus, inferior fronto⁃occipital fasciculus, left middle longitudinal fasciculus and forceps major were negatively correlated with the concentration of creatinine. The values of FA in the left arcuate fasciculus were positively correlated with the MoCA′s score, the values of MD and RD of these tracts were positively correlated with the concentration of creatinine, and negatively correlated with the scores of MMSE and MoCA. The values of FA in the right superior longitudinal fasciculus, the right corticospinal tract and the right frontal aslant tract werepositively correlated with the MoCA′s score, the values of MD and RD of these tracts were positively correlated with the concentration of urea; the values of MD and RD in the left fornix were positively correlated with the level of creatinine and urea. Conclusion The structural integrity of white matter in ESRD patients is extensively damaged, which is significantly associated with a variety of cognitive impairments. Serum creatinine and urea nitrogen may be risk factors for the changes in white matter.

Objective: To investigate the prognostic value of prognostic nutritional index (PNI) in patients with diffuse large B-cell lym-phoma (DLBCL). Methods: We retrospectively reviewed the medical records of 82 patients with DLBCL treated at Tianjin Union Medi-cal Center between June 2010 and June 2016. The optimal cutoff value of PNI was determined using a receiver operating characteristic (ROC) curve and the Youden index. The relationship of high and low PNI with the clinical characteristics of the patients, therapeutic ef-ficacy, and prognosis were analyzed. Results: Overall, mean PNI of the patients was 46.17±8.8. When the PNI was 44.15, the Youden in-dex was found to be maximal, with a sensitivity of 74.6% and specificity of 67.2%. There were 38 patients (46.3%) in the low PNI group (<44.15) and 44 patients (53.7%) in the high PNI group (≥44.15). Data analysis showed that PNI was correlated with Eastern Coopera-tive Oncology Group performance status (ECOG PS), Ann Arbor stage, international prognostic index (IPI) score, and lactic acid dehydro-genase (LDH) level (P<0.05). The total effective rate of the low PNI group was significantly lower than that of the high PNI group (65.8% vs. 86.4%; χ2=4.848; P=0.028). The 3-year overall survival (OS) rate of the entire group of patients was 69.1%. The 1-, 2-, and 3-year OS rates of the low PNI group (86.8%, 67.8%, and 56.9%, respectively) were significantly lower than that of the high PNI group (96.7%, 89.5%, and 80.2%, respectively; χ2=9.421, P=0.002). Univariate analysis showed that PNI<44.15, ECOG PS≥2, IPI>2, stageⅢ/Ⅳ, and lymphocyte count<1.0×109/L had a significant impact on predicting OS (P<0.05). Multivariate analysis showed that PNI<44.15 (P=0.006) and stageⅢ/Ⅳ(P=0.011) were independent factors for predicting OS. Conclusions: PNI might be used as a simple and feasible clinical prognostic indicator in patients with DLBCL.
