		                        			Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

		                        			Objective  To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods  A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results  A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.

		                        			Objective:To explore the effect of timely induction intervention on postpartum urination in primipara during vaginal delivery, so as to provide the evidence for preventing the occurrence of postpartum urinary retention and relieving the pain of primipara.Methods:This study adopted a randomized controlled trial design, and selected 400 cases of primipara who were hospitalized for vaginal delivery in the Obstetric Department of Dalian Women and Children's Medical Group Sports New Town Hospital from June 2021 to September 2022 as the study objects by convenience sampling method. They were divided into the intervention group and the control group with 200 cases each by random number table method, and the control group received routine postpartum care. Instruct active urination within 6 hours after delivery. The intervention received timely induction urination intervention. The general condition and bladder urine volume of the women in the intervention group were evaluated at 2, 4, 6 h after delivery, respectively, and personalized guidance was implemented, including the frequency of massage of the bottom of the uterus, the control of water intake, the selection of methods and timing of inducing urination, etc., and routine postpartum care was given when the women completed their first urination and had no complaints of discomfort. The first urination time, first urination volume, first bladder irritation during the first urination and the incidence of postpartum urinary retention in different periods were compared between the two groups.Results:The patients in the control group were (29.60 ± 3.20) years old, while the patients in the intervention group were (28.81 ± 3.42) years old. The first urination time in the intervention group was (6.89 ± 2.18) h, which was shorter than that in the control group (9.11 ± 3.86) h, and the difference was statistically significant ( t=-2.49, P<0.01). The first urination volume in the intervention group was (322.36 ± 120.15) ml, which was higher than that in the control group (262.93 ± 105.68) ml, and the difference was statistically significant ( t=3.39, P<0.05). The incidence of the first bladder irritation in the intervention group was 22.0%(44/200), which was lower than that in the control group 33.5%(67/200), and the difference was statistically significant ( χ2=6.60, P<0.05). The incidence of postpartum urinary retention within 24 h in the intervention group was 5.5%(11/200), which was lower than that in the control group 11.5%(23/200), and the difference was statistically significant ( χ2=4.63, P<0.05). The incidence of postpartum urinary retention within 1 week in the intervention group was 9.5%(19/200), which was lower than that in the control group 16.5%(33/200), and the difference was statistically significant ( χ2=4.33, P<0.05). There was no significant difference in the incidence of postpartum urinary retention within 24 to 72 h between the two groups ( P>0.05). Conclusions:Timely induction intervention can reduce the incidence of postpartum urinary retention, shorten the time of first urination, increase the volume of first urination and improve the comfort of first urination, which is worthy of clinical application.

		                        			Objective:To investigate the clinicopathological features of colorectal adenocarcinoma with enteroblastic differentiation (CAED).Methods:Eight cases of CAED diagnosed at the Department of Pathology, Fudan University Shanghai Cancer Center, Shanghai, China from January 2017 to August 2023 were collected. The histopathological, immunohistochemical, molecular and prognostic features of 8 CAED cases were analyzed. The relevant studies were also reviewed.Results:Among the eight patients, there were six males and two females, with an average age of 58 years (range: 29-77 years, median age: 61.5 years). Preoperative serum alpha-fetoprotein levels were elevated in five patients (14.0-286.6 μg/L). Four tumors were located in the colon, and four tumors in the rectum. Two patients were clinically staged as advanced stage (stage Ⅳ), and distant metastasis occurred at the initial diagnosis (one case had liver metastasis, and the other had lung, bone and multiple lymph nodes metastases). Six patients were clinically staged as locally-advanced stage (Stage Ⅱ-Ⅲ). Three of them developed distant metastases after surgery (one case had liver metastasis, one case had lung metastasis, and one case had peritoneal metastasis). Additionally, two patients died at 9 months and 24 months after surgery, respectively. The tumors were composed of various proportions of adenocarcinoma components with enteroblastic differentiation (30%-100%) and classical tubular adenocarcinoma components. The component with enteroblastic differentiation exhibited morphology similar to embryonic intestinal epithelium: cuboidal or columnar tumor cells arranged in tubular, papillary, cribriform, or solid nest patterns, with clear cytoplasm. Immunohistochemical studies showed that tumor cells expressed at least one oncofetal protein (SALL4, Glypican-3, and AFP). In addition, focal squamous differentiation was observed in 3 cases (3/8). Compared to the primary tumor, both CAED and squamous differentiation components were increased in the metastatic tumors. Based on the sequencing results of KRAS, NRAS and BRAF of the primary and/or metastatic tumors, 5 cases were wild-type, while KRAS exon 2 (G13D) mutations were identified in 2 cases.Conclusions:CAED is a rare colorectal malignancy with a dismal prognosis. Accurate pathological diagnosis is prognostically valuable. The histological features of enteroblastic differentiation, elevated serum AFP levels, and the expression of oncofetal proteins play an important role in the tumor diagnosis.

		                        			Objective:To investigate the changes in the white matter fiber structure of fetal brain with mild to moderate isolated ventriculomegaly (IVM) using diffusion tensor imaging (DTI) model and fixed based analysis (FBA) method of diffusion MRI (dMRI).Methods:This was a case-control study. Twenty fetuses diagnosed with mild to moderate IVM who were admitted to the Provincial Hospital Affiliated to Shandong First Medical University from August 2022 to August 2023 were included prospectively as the IVM group, with gestational age ranging from 24 to 36 (29.9±3.6) weeks. The control group included 22 normal control fetuses obtained from the dMRI atlas data of Chinese fetal brain, with gestational age ranging from 24 to 36 (30.2±3.7) weeks. The dMRI data were collected for all fetuses and the DTI model was used to obtain fractional anisotropy (FA), mean diffusivity, axial diffusivity, and radial diffusivity of 7 main fiber bundles, including the genu and splenium of the corpus callosum, middle cerebellar peduncle, bilateral cortico-spinal tract, inferior longitudinal fasciculus, inferior fronto-occipital fasciculus, and anterior thalamic radiation. The FBA method was used to obtain fiber density (FD), fiber cross-sectional area (FC), and fiber density and cross-section (FDC) of the whole brain. The comparison of DTI parameters of each fiber bundle between the two groups was conducted using independent sample t test or Mann-Whitney U test. The comparison of FBA parameters between the two groups was performed using covariance analysis, and the MRtrix3 software package was used to display the brain regions with significant differences. Results:The FA values of the inferior longitudinal fasciculus in the IVM group and the control group were 0.142±0.012 and 0.133±0.015, respectively, and the difference was statistically significant ( t=2.21, P=0.033), while the DTI parameters of the other fiber bundles showed no statistically significant differences ( P>0.05). The whole brain FBA results showed that compared with the control group,FD decreased while FC increased in the corpus callosum, fornix, and sagittal stratum in IVM fetuses, while FDC decreased in the cortico-spinal tract. Conclusion:There are microstructural changes of the brain white matter fiber in intrauterine fetuses with mild to moderate IVM, which are mainly located in the white matter fiber bundles surrounding the body, atrium, and temporal horn of the lateral ventricle.
