Objective:The primary goal of this study is to explore the safety and effectiveness of a new modified eversion carotid endarterectomy (MECEA).Methods:This is a retrospective case series study. One hundred patients were consecutively treated with MECEA by the same operator at Department of Vascular Surgery,Peking Union Medical College Hospital from January 2019 to December 2023. There were 77 males and 23 females. The age was (66.0±8.6)years (range: 39 to 85 years). Twenty-four (24.0%) patients were symptomatic with the degree of carotid stenosis over 50%,76 patients (76.0%) were asymptomatic with the degree of stenosis over 70%. All these patients meet the indication of carotid endarterectomy. The main difference between MECEA and traditional eversion carotid endarterectomy was the anterior,lateral,and posterior walls of the internal carotid artery were incised obliquely from the origin of the internal carotid artery toward the common carotid artery,leaving the wall of internal carotid artery intact at the bifurcation. The surgical process,cardiovascular and cerebrovascular complications and other surgical complications were recorded. The incidences of complications,restenosis of intraoperative target lesions and re-intervention were collected during follow-up.Results:All procedures were performed successfully under general anesthesia. The total operation time was (36.5±10.1)minutes (range: 22 to 65 minutes),and carotid clamping time was (15.0±6.3)minutes (range: 7 to 31 minutes). One patient (1.0%) occurred postoperative cerebrovascular accident,1 patient (1.0%) developed cerebral hyperperfusion syndrome (CHS),and another 1 patient (1.0%) suffered myocardial infarction. All these patients were recovered after medical treatment within a week. The follow-up time( M(IQR)) was 24 (28) months (range: 6 to 62 months). Two patients (2.0%) were reported to have hemodynamically significant restenosis within 2 years,with one patient requiring intervention. No patient suffered from ipsilateral ischemic stroke. Conclusions:MECEA is a safe and effective surgical method of treating carotid artery stenosis. This method can reduce carotid clamping time and lowers the risk of ischemic stroke. Meantime,it preserves the integrity of the adventitia at the bifurcation of carotid artery,reduces the chance of restenosis. Moreover,it might be helpful to prevent postoperative CHS due to reducing damage to the carotid body and carotid sinus nerve.

ObjectiveTemporal heterogeneity in lung cancer presents as fluctuations in the biological characteristics, genomic mutations, proliferation rates, and chemotherapeutic responses of tumor cells over time, posing a significant barrier to effective treatment. The complexity of this temporal variance, coupled with the spatial diversity of lung cancer, presents formidable challenges for research. This article will pave the way for new avenues in lung cancer research, aiding in a deeper understanding of the temporal heterogeneity of lung cancer, thereby enhancing the cure rate for lung cancer. MethodsRaman spectroscopy emerges as a powerful tool for real-time surveillance of biomolecular composition changes in lung cancer at the cellular scale, thus shedding light on the disease’s temporal heterogeneity. In our investigation, we harnessed Raman spectroscopic microscopy alongside multivariate statistical analysis to scrutinize the biomolecular alterations in human lung epithelial cells across various timeframes after benzo(a)pyrene exposure. ResultsOur findings indicated a temporal reduction in nucleic acids, lipids, proteins, and carotenoids, coinciding with a rise in glucose concentration. These patterns suggest that benzo(a)pyrene induces structural damage to the genetic material, accelerates lipid peroxidation, disrupts protein metabolism, curtails carotenoid production, and alters glucose metabolic pathways. Employing Raman spectroscopy enabled us to monitor the biomolecular dynamics within lung cancer cells in a real-time, non-invasive, and non-destructive manner, facilitating the elucidation of pivotal molecular features. ConclusionThis research enhances the comprehension of lung cancer progression and supports the development of personalized therapeutic approaches, which may improve the clinical outcomes for patients.

Objective: To explore the characteristics and correlations of vaginal flora in women with cervical lesions. Methods: A total of 132 women, including 41 women diagnosed with normal cervical (NC), 39 patients with low-grade cervical intraepithelial neoplasia (CIN 1), 37 patients with high-grade cervical intraepithelial neoplasia (CIN 2/3) and 15 patients with cervical squamous cell carcinoma (SCC), who came from the gynecological clinic of Second Hospital of Shanxi Medical University during January 2018 to June 2018, were enrolled in this study according to the inclusive and exclusive criteria strictly. The vaginal flora was detected by 16S rDNA sequencing technology. Co-occurrence network analysis was used to investigate the Spearman correlations between different genera of bacteria. Results: The dominant bacteria in NC, CIN 1 and CIN 2/3 groups were Lactobacillus [constituent ratios 79.4% (1 869 598/2 354 098), 63.6% (1 536 466/2 415 100) and 58.3% (1 342 896/2 301 536), respectively], while Peptophilus [20.4% (246 072/1 205 154) ] was the dominant bacteria in SCC group. With the aggravation of cervical lesions, the diversity of vaginal flora gradually increased (Shannon index: F=6.39, P=0.001; Simpson index: F=3.95, P=0.012). During the cervical lesion progress, the ratio of Lactobacillus gradually decreased, the ratio of other anaerobes such as Peptophilus, Sneathia, Prevotella and etc. gradually increased, and the differential bacteria (LDA score >3.5) gradually evolved from Lactobacillus to other anaerobes. The top 10 relative abundance bacteria, spearman correlation coefficient>0.4 and P<0.05 were selected. Co-occurrence network analysis showed that Prevotella, Peptophilus, Porphyrinomonas, Anaerococcus, Sneathia, Atopobium, Gardnerella and Streptococcus were positively correlated in different stages of cervical lesions, while Lactobacillus was negatively correlated with the above anaerobes. It was found that the relationship between vaginal floras in CIN 1 group was the most complex and only Peptophilus was significantly negatively correlated with Lactobacillus in SCC group. Conclusions: The increased diversity and changed correlations between vaginal floras are closely related to cervical lesions. Peptophilus is of great significance in the diagnosis, prediction and early warning of cervical carcinogenesis.

Objective:To analyze the value of shear wave elastography (SWE) in evaluating carotid artery elasticity in type 2 diabetes mellitus (T2DM) patients with nonalcoholic fatty liver disease (NAFLD).Methods:A total of 98 T2DM patients diagnosed in the Second Affiliated Hospital of Dalian Medical University were selected and divided into three groups according to the results of liver ultrasound examination. 35 patients without NAFLD were in group A, 33 patients with mild NAFLD were in group B, and 30 patients with moderate to severe NAFLD were in group C. All selected individuals showed no plaque formation on carotid ultrasound examination. Left carotid artery intima-media thickness (IMT), carotid artery systolic diameter (Ds), carotid artery diastolic diameter (Dd), and peak systolic velocity (PSV) were measured using conventional two-dimensional and M-mode ultrasound. The stiffness coefficient (β) was obtained through calculation. SWE was used to measure the mean longitudinal modulus of elasticity (MEmean), mean minimum modulus of elasticity (MEmin), and mean maximum modulus of elasticity (MEmax) of the left carotid artery at the end of diastole.Results:There was no statistically significant difference in Ds, Dd, and PSV among the three groups (all P>0.05). Compared with group A and group B, group C had significantly higher IMT, β, MEmean, MEmax, and MEmin (all P<0.05). Compared with the group A, the group B had higher levels of MEmean, MEmax, and MEmin (all P<0.05), there was no statistically significant difference in IMT and β between the groups (all P>0.05). Correlation analysis showed that MEmax, MEmean, and MEmin in each group were positively correlated with β ( r=0.537, 0.543, 0.525, P<0.01), and also positively correlated with HbA 1c ( r=0.456, 0.483, 0.438, P<0.01), but not with IMT (all P>0.05). The intra observer Intraclass correlation coefficient (ICC) of MEmax, MEmean and MEmin measured by SWE was 0.847-0.887, and the inter observer ICC was 0.791-0.934, indicating a good repeatability. Conclusions:SWE can quantitatively evaluate the elasticity of the carotid artery in patients with T2DM and NAFLD.

Objective:To explore the clinical manifestations and genetic characteristics of Wolf-Hirschhorn syndrome (WHS) to improve the ability of diagnosis and differential diagnosis of the disease.Methods:The clinical features and auxiliary examinations and treatment of a proband with WHS caused by microdeletion of 4p16.3 segment who admitted to the Third Affiliated Hospital of Zhengzhou University in December 2021 were recorded, and whole exome sequencing (WES) of the family was performed. The prognosis was followed up.Results:The female proband, 11 months old, presented with convulsions at the age of 8 months, with the characteristics of heat sensitivity and cluster seizures, and her identical twin sister had a similar medical history. Physical examination found malnutrition, retarded development, special face, prominent forehead, wide nasal bridge, small jaw, precordial murmur and grade 3/6 murmur in the whole period, hyperactivity of P2, and low limb muscle tone. The whole exon and copy number variation (CNV) test of the family revealed that the proband had a 1.99 Mb heterozygous deletion in the chromosome 4p16.3 segment, including WHSC1 (NSD2), WHSC2 (NEFLA) and other genes. Copy number variation sequencing (CNV-Seq) of the proband and her sister showed 1.97 and 1.92 Mb heterozygous deletion of chromosome 4p16.3, respectively. Genealogical analysis by quantitative polymerase chain reaction revealed that the CNV was de novo, and it was determined to be a pathogenic variant according to the American College of Medical Genetics and Genomics guidelines. The proband took sodium valproate orally, and her sister took oral sodium valproate, zonisamide, and levetiracetam successively, and at the same time they received family rehabilitation training. The age at the last follow-up was 1 year and 8 months. Neither of them had convulsions again in the past 3 months, but the developmental delay was obvious. Conclusion:WHS patients may present with growth retardation, epilepsy, Greek warrior helmet-like special face, and congenital heart disease, and may have microdeletions in the chromosome 4p16.3 segment.

Objective: To investigate the effect of embryo quality at different developmental stages on the secondary sex ratio (SSR) of single live birth neonates. Methods: Data for patients with singleton live births after embryo transferred between January 2016 and January 2022 were retrospectively analyzed. The effect of embryo quality at different development stages on the SSR of 11 713 singleton live births were investigated. The association of SSR and embryo quality at different development stages was examined in univariate analysis and in a multivariate logistic regression model, after adjustment for confounders, using two models (Ⅰ and Ⅱ). Results: The age of both male and female, body mass index of both male and female, basal follicle stimulating hormone and estradiol, smoking of male, methods of insemination, methods of sperm extraction, types of transfer cycle and the number of embryo transferred were not related with SSR (all P>0.05). After adjustment for confounders, the probability of a male live birth was higher after transfer of good-quality blastula than after transfer of poorer-quality blastula (model Ⅰ: aOR=0.73, 95%CI: 0.65-0.82, P<0.001; model Ⅱ: aOR=0.73, 95%CI: 0.65-0.82, P<0.001). The quality of cleavage stage embryo was not associated with SSR (model Ⅰ: aOR=0.99, 95%CI: 0.87-1.13, P=0.937; model Ⅱ: aOR=0.99, 95%CI: 0.87-1.13, P=0.899). Conclusions: The SSR of singleton live births after embryo transfer is not correlated with the quality of cleavage stage embryo, but is correlated with the quality of blastula. Good-quality blastula transfer is more likely to result in a male live birth.

Objective: To analyze the efficacy, safety, and long-term prognosis of intermediate-dose cytarabine (Ara-c) regimen in the treatment of children with refractory risk organ involvement Langerhans cell histiocytosis (LCH). Methods: Clinical data of 17 children with multisystem and risk organ involvement LCH who failed the first-line therapy and were treated with intermediate-dose Ara-c (250 mg/m², twice daily) regimen in the Hematology Center, Beijing Children's Hospital from January 2013 to December 2016 were analyzed retrospectively. In addition to the basic treatment of vindesine and dexamethasone, the patients received two regimens: regimen A: the intermediate-dose Ara-c combined with cladribine and regimen B: the intermediate-dose Ara-c alone. The efficacy, safety and prognosis of the two regimens were analyzed. Results: Among all 17 patients, there were 11 males and 6 females, with the diagnosis age of 2.1 (1.6, 2.7) years. Ten children received regimen A, all of them achieved active disease-better (AD-B) after 8 courses of induction therapy. The disease activity scores (DAS) decreased from 5.5 (3.0, 9.0) to 1.0 (0, 2.3). Seven children received regimen B, and 6 of them achieved AD-B after 8 courses of induction therapy. The DAS decreased from 4.0 (2.0, 4.0) to 1.0 (0, 2.0). The follow-up time was 6.2 (4.9,7.2) and 5.2 (3.7,5.8) years in group A and B. The 5-year overall survival rate was 100.0% in both groups, and the 5-year event free survival rate was (88.9±10.5)% and (85.7±13.2)% in group A and B. Grade 3 or 4 myelosuppression was observed in 8 patients in group A and 2 patients in group B. Conclusions: The intermediate-dose Ara-c regimen (with or without cladribine) is effective and safe for patients with refractory high-risk LCH, with a good long-term prognosis.
