ObjectiveTo investigate the prevalence of polycystic ovary syndrome （PCOS） among female college students at a university in Fuzhou City， Jiangxi Province， and to facilitate early detection and intervention of PCOS. MethodsUsing a stratified sampling method， a total of 450 female freshmen were randomly selected for PCOS screening. A self-designed questionnaire was used for data collection， covering menstrual status， high androgen signs， lifestyle， dietary habits， and awareness of PCOS. Sample t test and χ² test were used to compare the basic information and dietary habits between PCOS and non-PCOS cases. The correlation between various indicators and the prevalence of PCOS was analyzed by a logistic regression model. ResultsA total of 12 PCOS cases were identified， with a prevalence rate of 2.99%. PCOS cases exhibited statistically significant differences compared to non-PCOS cases in terms of waist-to-hip ratio， waist circumference， abdominal obesity， the proportion of overweight or obese individuals， and a preference for sweet food （all P<0.05）. Multivariate logistic regression analysis revealed a significant correlation between preference for sweet food and the occurrence of PCOS （OR=4.858， 95%CI=1.199‒19.675，P=0.027）， as well as a significant correlation with PCOS accompanied by abdominal obesity （OR=7.083， 95%CI=0.773‒64.937， P=0.048）. Among the female college students surveyed， 37.90% had never heard of PCOS， 51.62% were only familiar with the name of the disease， and 10.47% had attempted to search for PCOS-related information. ConclusionThe prevalence of PCOS among female college students should not be overlooked and unhealthy dietary habits may be a crucial factor contributing to the occurrence of PCOS during this period. Early screening for PCOS during puberty is crucial.

To investigate the perinatal features of fetal Kaposiform hemangioendothelioma(KHE)complicated with Kasabach-Merritt syndrome(KMS),we reported an incidental ultrasound finding of a subcutaneous mass on the back of the foetus in a 36-year-old woman at 38 weeks of pregnancy,with no other abnormal prenatal findings.The dorsal mass was hypoechoic,approximately 6-7 cm in diameter,and Doppler showed a striated blood flow signal.Fetal growth measurements were consistent with gestational age,and the amniotic fluid volume was normal.A live-born boy was delivered by caesarean section.The neonate had a large subcutaneous haemangioma on the left dorsum with thrombocytopenia and coagulopathy.He was diagnosed with KMS and was treated with intravenous high dose pulse methylprednisolone,sirolimus,surgical resection and blood transfusion.Histopathological and immunohistochemical findings confirmed tufted hemangioma and KHE.There was no residual recurrence on postoperative follow-up of 6 months.

Objective This study aimed to explore the heterogeneity and gene ontology of Wnt1-Cre-marked and Pax2-Cre-marked first branchial arch cranial neural crest cells(CNCs)in mice.Methods The embryos of Wnt1-Cre;R26RmTmG and Pax2-Cre;R26RmTmG at embryonic day(E)8.0-E9.25 were collected for histological observation.We per-formed immunostaining to compare green fluorescent pro-tein(GFP)-positive CNCs in Pax2-Cre;R26RAi9 and Wnt1-Cre;R26RAi9 mice at E15.5.Single-cell RNA sequencing(scRNA-seq)was used to analyze the first branchial arch GFP-positive CNCs from Wnt1-Cre;R26RmTmG and Pax2-cre;R26RmTmGmice at E10.5.Real time fluorescence quantitative polymerase chain reaction(q-PCR)was performed to val-idate the differential genes.Results Wnt1-Cre-marked and Pax2-Cre-marked CNCs migrated from the neural plateto first and second branchial arches and to the first branchial arch,respectively,at E8.0.Although Wnt1-Cre-marked and Pax2-Cre-marked CNCs were found mostly in cranial-facial tissues,the former had higher expression in palate and tongue.The results of scRNA-seq showed that Pax2-Cre-marked CNCs specifically contributed to osteoblast differentia-tion and ossification,while Wnt1-Cre-marked CNCs participated in limb development,cell migration,and ossification.The q-PCR data also confirmed the results of gene ontology analysis.Conclusion Pax2-Cre mice are perfect experimen-tal animal models for research on first branchial arch CNCs and derivatives in osteoblast differentiation and ossification.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.

Purpose To analyze the morphological charac-teristics of papillary thyroid carcinoma(PTC)patients with NTRK gene fusion in order to provide more important morpholog-ic evidences for molecular detection.Methods A retrospective collection of 790 cases PTC was conducted.Then the patients with NTRK gene fusion were selected.The histopathological fea-tures of PTC patients with NTRK gene fusion were compared with those of classical PTC.Results Nine cases(1.1%)of NTRK fusion positive PTC were detected,including 2 cases of NTRK1 and 7 cases of NTRK3 gene fusion.The main his-topathological features were follicular subtypes,with tumors ex-hibiting multinodular infiltration or"jumping"infiltration.The cytoplasm was associated with hyaline change.The cell morphol-ogy was slight irregularity.Conclusion The incidence of NTRK fusion is low in PTC and it tends to occur in the young group.Follicular subtype is the main characteristic histopatholo-gy,with mild tumor cells.But the ability of the invasion and metastasis is strong.Therefore,NGS detection should be per-formed for early intervention and prolonging the survival of PTC patients.
