ABSTRACT

Background: Persistent HR-HPV causes cervical cancer, exhibiting geographic variance. Europe/Americas have higher HPV16/18 rates, while Asia/Africa predominantly have non-16/18 HR-HPV. This study in Fujian, Asia, explores non-16/18 HR-HPV infections, assessing their epidemiology and cervical lesion association for targeted prevention. Methods: A total of 101,621 women undergoing HPV screening at a hospital in Fujian Province from 2013 to 2019 were included. HPV genotyping was performed. A subset of 11,666 HPV-positive women with available histopathology results were analyzed to characterize HPV genotype distribution across cervical diagnoses. Results: In 101,621 samples, 24.5% tested positive for HPV. Among these samples, 17.3% exhibited single infections, while 7.2% showed evidence of multiple infections. The predominant non-16/18 high-risk HPV types identified were HPV 52, 58, 53, 51, and 81. Single HPV infections accounted for 64.1% of all HPV-positive cases, with 71.4% of these being non-16/18 high-risk HPV infections. Age-related variations were observed in 11,666 HPV-positive patients with pathological results. Cancer patients were older. In the cancer group, HPV52 (21.8%) and HPV58 (18.6%) were the predominant types, followed by HPV33, HPV31, and HPV53. Compared to single HPV16/18 infection, non-16/18 HPV predominated in LSIL. Adjusted odds ratios (OR) for LSIL were elevated: multiple HPV16/18 (OR 2.18), multiple non-16/18 HR-HPV (OR 2.53), and multiple LR-HPV (OR 2.38). Notably, solitary HPV16/18 conferred higher odds for HSIL and cancer. Conclusion: Our large-scale analysis in Fujian Province highlights HPV 52, 58, 53, 51, and 81 as predominant non-16/18 HR-HPV types. Multiple HPV poses increased LSIL risks, while solitary HPV16/18 elevates HSIL and cancer odds. These findings stress tailored cervical cancer prevention, highlighting specific HPV impacts on lesion severity and guiding region-specific strategies for optimal screening in Asia, emphasizing ongoing surveillance in the vaccination era.

ABSTRACT

Background: Adenocarcinoma is a common histological subtype of cervical cancer, accounting for 10-15% of all cases. The prognosis of cervical adenocarcinoma with distant organ metastases remains unclear. Therefore, our study aimed to investigate the patterns and prognosis of distant organ metastasis in cervical adenocarcinoma. Methods: We obtained data from the Surveillance, Epidemiology, and End Results (SEER) database spanning from 2010 to 2019. Cox regression, Kaplan-Meier, and log-rank analyses were conducted. Results: We observed that adenocarcinoma (AC) of the cervix primarily metastasizes to single organs, with a rate of 73.3%. The lungs are the most common organs of metastasis, followed by the liver and bones. Patients with bone metastases have a median survival period of 12 months, which is slightly longer compared to metastasis in other organs. Distant organ metastasis, age, positive lymph nodes, higher AJCC stages, larger tumor diameter, and higher cell grades are related to poor prognosis (p < 0.001). Furthermore, we have observed that surgical intervention, radiotherapy, and chemotherapy can potentially provide benefits for patients with distant organ metastases. Conclusion: Metastasis is an independent prognostic factor for cervical adenocarcinoma patients. Surgery, radiotherapy, and chemotherapy can provide an overall survival advantage for patients with distant organ metastases.

ABSTRACT

Reports have pointed out that nearly 50% of the global total energy demand for buildings is used for daily heating and cooling. Therefore, it is very important to develop various high-performance thermal management techniques with low energy consumption. In this work, we present an intelligent shape memory polymers (SMPs)-based device with programmable anisotropic thermal conductivity fabricated by a 4D printing technique to assist in thermal management with net zero energy. Highly thermal conductive BN nanosheets were textured in a poly (lactic acid) (PLA) matrix by 3D printing, and the printed composites lamina exhibited significant anisotropic thermal conductivity. The direction of heat flow in devices could be switched programmably, accompanying the light-activated deformation controlled by grayscale of composite, which was demonstrated by the "windows" arrays composed of in-plate thermal conductivity facets and SMPs-based hinge joints, achieving the programmable movement of opening and closing under different light conditions. Based on solar radiation-dependent SMPs coupled with the adjustment of heat flow along anisotropic thermal conductivity, the 4D printed device has been proved in concept for potential applications in thermal management in a building envelop for dynamic climate adaptation, taking place automatically based on the environment.

ABSTRACT

Identifying BRCA mutations and homologous recombination deficiency (HRD) is the key to choosing patients for poly (ADP-ribose) polymerase inhibitor (PARPi) therapy. At present, a large amount of research focuses on the application of HRD detection in ovarian cancer. However, few studies have discussed the relationship between HRD detection and postoperative survival in patients with epithelial ovarian cancer (EOC). This study included 38 consecutive patients with EOC who underwent cytoreduction surgery. Owing to tissue availability, only 29 patients underwent molecular profiling and survival analysis. Overall, 21 (72.4%) tumors had HRD scores of ≥42. Mutations in BRCA were observed in 5/29 (17.2%) patients. In this cohort, an HRD score of ≥42 was more common in serous ovarian tumors. We found no statistically significant association between homologous recombination repair (HRR) genes and HRD scores except for tumor protein P53 (TP53) mutation. We also found a strong positive association between HRD scores and chromosomal instability (CIN). In the survival analysis, an HRD score of >23 was correlated with better postoperative progression-free survival (pPFS). With increased depth of research, an appropriate HRD score threshold may serve as a prognostic tool and should be assessed in future studies to predict the clinical value of PARPi.

ABSTRACT

OBJECTIVE: To explore the accuracy related to type and subtype between frozen section (FS) results and final pathology results in patients with endometrial cancer and to suggest whether it should be routinely performed. METHODS: Retrospective data were collected from 184 patients with endometrial cancer who underwent surgery at a single center (January 2014-December 2018). FS results were compared with the final pathology results with respect to histotype, tumor grade, and depth of invasion to define the accuracy of FS analysis. RESULTS: Frozen section analysis was performed in 141 (76.6%) patients. The accuracy rates and κ values between the FS and final pathology results with respect to histotype, tumor grade, and depth of invasion were 87.23%, 81.15%, and 98.2% and 0.41, 0.7, and 0.9, respectively (P < 0.001). Among the 18 patients with preoperative non-endometrioid cancer (non-EC), six underwent FS analysis, and final pathology confirmed EC in three, of whom 75% were detected by FS analysis. Eight of 19 patients with preoperative grade 3 EC underwent FS analysis and the accuracy rate was 87.5%. CONCLUSION: Intraoperative FS analysis is a reliable method that can help intraoperative decision making. It should be performed routinely in patients with non-EC and grade 3 EC.

ABSTRACT

To investigate preoperative platelet morphology parameters and other whole blood cells in patients of malignant endometrial carcinoma compared with benign disease.Retrospective analysis was performed through collecting patients' hematological parameters before performing total abdominal/vaginal hysterectomy and standard radical surgery due to benign and malignant endometrial disease between 2006 and 2017. Parameters required included white blood cell (WBC), hemoglobin, platelet count (PLT), platelet distribution width (PDW), mean platelet volume (MPV), and platelet thrombocytocrit (PCT). And neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were calculated. For malignant carcinoma, Ki-67 percentage and progesterone receptor (PR) status were further collected.A total of 288 patients were included with 145 benign cases and 143 malignant cases. Patients of confirmed endometrial carcinoma showed a significant lower value of PDW (55.21 ±â€Š4.72 vs 49.54 ±â€Š5.89, P < .001), meanwhile significant higher values of MPV (7.12 ±â€Š1.56 vs 8.89 ±â€Š1.67, P < .001) and PCT (24.18 ±â€Š6.89 vs 27.93 ±â€Š8.93, P = .003). Further analysis of endometrial carcinoma patients showed that no significant difference in platelet parameters was found between patients with stage I to II and stage III to IV (P > .05), while increased value in PDW and reduced value in MPV was found in PR negative compared with positive patients.Preoperative platelet morphology parameters seemed to be used as one kind of predictive factors to discriminate malignant and benign endometrial disease. Limited by present study design, further prospective studies are required to support this finding.

ABSTRACT

Stroke is reported as a leading cause of mortality and disability in the world. Neuroinflammation is significantly induced responding to ischemic stroke, and this process is accompanied with microglial activation. However, the pathogenesis contributing to ischemic stroke remains unclear. NR4A1 (Nur77) is a nuclear receptor that is expressed in macrophages, playing a significant role in regulating inflammatory response. In the present study, we attempted to explore the effects of NR4A1 on ischemic stroke using in vivo and in vitro studies. Results suggested that NR4A1 expression in microglia was markedly increased after cerebral ischemic damage. Then, we found that NR4A1 knockout attenuated ischemia-triggered infarction volume and neuron injury. Also, cognitive impairments were improved in ischemic mice with NR4A1 deficiency, resulting in functional improvements. Moreover, M1 polarization in microglia and neutrophil recruitment was significantly alleviated by NR4A1 deletion, as evidenced by the reduced expression of M1 markers, chemokines, as well as intracellular adhesion molecule-1 (ICAM-1) and myeloperoxidase (MPO) levels. Importantly, we found that NR4A1 could interact with nuclear factor-κB (NF-κB)/p65 based on in vivo and in vitro results. Suppressing p65 activation by the use of its inhibitor clearly reduced the NR4A1 expression, M1 polarization and neutrophil recruitments, while rescued the expression of anti-inflammatory factors in microglia treated with oxygen-glucose deprivation (OGD). Therefore, NR4A1 suppression in microglia restrained neuroinflammation through interacting with NF-κB/p65 to attenuate ischemic stroke.

ABSTRACT

In this work, three-dimensional cactus-like Co3O4@Ni(OH)2 electrode materials are grown directly on Ni foam via a two-step hydrothermal method. The as-prepared products possess a specific capacitance of 464.5 C g-1 at 0.5 A g-1 and 91.67% capacitance retention after 20 000 cycles. The as-assembled device using the as-synthesized samples as positive electrodes delivers an energy density of 112.5 W h kg-1 at a power density of 1350 W h kg-1. The superior electrochemical performance of the electrode materials can be attributed to their unique structure, the synergistic effect between Co3O4 and Ni(OH)2 materials and reversible reaction kinetics. It suggests that the products are potential alternatives in future energy storage devices.

ABSTRACT

OBJECTIVE: Pretreatment of myoinositol is a very new method that was evaluated in multiple small studies to manage poor ovarian response in assisted reproduction. This study was to determine the efficacy of myoinositol supplement in infertile women undergoing ovulation induction for intracytoplasmic sperm injection (ICSI) or in vitro fertilization embryo transfer (IVF-ET). METHODS: A meta-analysis and systematic review of published articles evaluating the efficacy of myo-inositol in patients undergoing ovulation induction for ICSI or IVF-ET was performed. RESULTS: Seven trials with 935 women were included. Myoinositol supplement was associated with significantly improved clinical pregnancy rate [95% confidence interval (CI), 1.04-1.96; P = .03] and abortion rate (95% CI, 0.08-0.50; P = .0006). Meanwhile, Grade 1 embryos proportion (95% CI, 1.10-2.74; P = .02), germinal vescicle and degenerated oocytes retrieved (95% CI, 0.11-0.86; P = .02), and total amount of ovulation drugs (95% CI, -591.69 to -210.39; P = .001) were also improved in favor of myo-inositol. There were no significant difference in total oocytes retrieved, MII stage oocytes retrieved, stimulation days, and E2 peak level. CONCLUSIONS: Myoinositol supplement increase clinical pregnancy rate in infertile women undergoing ovulation induction for ICSI or IVF-ET. It may improve the quality of embryos, and reduce the unsuitable oocytes and required amount of stimulation drugs.

ABSTRACT

To determine whether myo-inositol supplement will increase the action of endogenous insulin, which is mainly measured by markers of insulin resistance such as homeostasis model assessment of insulin resistance.PubMed, Cochrane Library, Embase, and web of science were comprehensively searched using "gestational diabetes mellitus" and "myo-inositol" to identify relevant studies. Both subject headings and free texts were adopted. The methodological quality of the included studies were assessed and pooled analyzed by the methods recommended by the Cochrane collaboration.A total of 5 trials containing 513 participants were included. There was a significant reduction in aspects of gestational diabetes incidence (risk ratio [RR], 0.29; 95% confidence interval (95% CI), 0.19-0.44), birth weight (mean difference [MD], -116.98; 95% CI, -208.87 to -25.09), fasting glucose oral glucose tolerance test (OGTT) (MD, -0.36; 95% CI, -0.51 to -0.21), 1-h glucose OGTT (MD, -0.63; 95% CI, -1.01 to -0.26), 2-h glucose OGTT (MD, -0.45; 95% CI, -0.75 to -0.16), and related complications (odds ratio [OR], 0.28; 95% CI 0.14-0.58).On the basis of current evidence, myo-inositol supplementation reduces the development of gestational diabetes mellitus (GDM), although this conclusion requires further evaluation in large-scale, multicenter, blinded randomized controlled trials.

ABSTRACT

Epithelial ovarian cancer is the most lethal gynecological malignancies for readily metastasis. Exosomes have played an influential role in carcinogenicity and cancer progression. Our aim is to discover exosome-related mechanisms in ovarian cancer progress and explore potential diagnostic biomarkers and therapeutic targets of ovarian cancer. We initially presented the proteomic profiles of exosomes derived from two late-stage ovarian cell lines, OVCA429 and HO8910PM. A total of 2940 exosomal proteins were recorded by MS. FunRich appropriately processed these exosomal proteins, manifesting some superiority in contrast to Blast2go. Moreover, we demonstrated the pentose phosphate pathway was a dominant mechanism in exosome mediated intracellular communication. Glucose-6-phosphate dehydrogenase, transketolase and transaldolase 1, three key enzymes regulated pentose phosphate pathway, were all marked in the same exosomal parts of proteins between two ovarian cell lines. Moreover, these key proteins might become diagnostic, prognostic biomarkers and therapeutic targets of ovarian cancer.

ABSTRACT

Angiogenesis is crucial for the development and metastasis of human brain glioma. Based on our previous successful construction of a lentivirus-mediated alphastatin (an endogenous angiogenesis inhibitor) gene transfer system and our findings that alphastatin exhibited potent inhibitory effects on the migration and differentiation of human umbilical vein endothelial cell lines (HUVECs) induced by vascular endothelial growth factor (VEGF) or basic fibroblast growth factor (bFGF) in vitro, here, we investigated the effect of using lentiviral vectors to overexpress alphastatin in human glioma cells to show whether sustained long-term expression of alphastatin diminishes tumor growth in a xenograft glioma model. We found that the transduced glioma cells sustainedly secreted alphastatin, which did not affect the proliferative ability of the glioma cells. Furthermore, tumor xenografts treated with the recombinant lentivirus were significantly smaller compared to the control xenografts and vascularity within the treated tumors was evidently decreased. Our data suggest that stable expression of alphastatin inhibits human glioma growth by inhibiting angiogenesis, with a probable mechanism of suppressing the turnover of VE-cadherin membrane molecules.
