Targeting Aurora-A inhibits tumor progression and sensitizes thyroid carcinoma to Sorafenib by decreasing PFKFB3-mediated glycolysis.

Thyroid cancer (TC) is the most common endocrine tumor, amongst which anaplastic thyroid carcinoma (ATC) is the most deadly. Aurora-A usually functions as oncogenes, and its inhibitor Alisertib exerts a powerful antitumor effect in various tumors. However, the mechanism of Aurora-A in regulating TC cell energy supply remains unclear. In the present study, we demonstrated the antitumor effect of Alisertib and an association between high Aurora-A expression and shorter survival. Multi-omics data and in vitro validation data suggested that Aurora-A induced PFKFB3-mediated glycolysis to increase ATP supply, which significantly upregulated the phosphorylation of ERK and AKT. Furthermore, the combination of Alisertib and Sorafenib had a synergistic effect, further confirmed in xenograft models and in vitro. Collectively, our study provides compelling evidence of the prognostic value of Aurora-A expression and suggests that Aurora-A upregulates PFKFB3-mediated glycolysis to enhance ATP supply and promote TC progression. Combining Alisertib with Sorafenib has huge prospects for application in treating advanced thyroid carcinoma.

Effects of electroacupuncture on the expression of hypothalamic neuropeptide Y and ghrelin in pubertal rats with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome often starts in puberty, and its pathogenesis is not clear. This study aimed to explore the pathogenesis of pubertal polycystic ovary syndrome (PCOS) and assess the therapeutic effect of electroacupuncture on pubertal PCOS. METHODS: Dihydrotestosterone (DHT) was used to induce rat models of pubertal PCOS. pubertal rats with PCOS were randomly divided into a model group (M), an electroacupuncture group (EA), and a sham acupuncture group (SA). Age-matched normal rats were regarded as normal controls (N). Rats were treated with EA or SA five times a week for 25 minutes during their 6th-7th week. At the end of the experiment, we observed any changes in ovarian morphology; detected levels of metabolic indices in serum, the hypothalamus and pancreas. RESULTS: EA significantly improved estrous cycle disorders and the ovarian polycystic morphology in pubertal rats with PCOS, but SA only improved disorders of the estrous cycle. The serum levels of insulin, neuropeptide Y(NPY) and fasting blood glucose(FBG) increased significantly (both p < 0.01), while the serum levels of ghrelin(GHRL) decreased in the model group (p < 0.01). After treatment with EA, the levels of NPY (p < 0.01) and FBG (p < 0.05) went into decrease, whereas the levels of GHRL (p < 0.05) and insulin (p < 0.01) increased. There was few differences in the hypothalamic expression of galanin (GAL), galanin-like peptide (GALP) and ghrelin receptor(GHSR) between the four groups. The upregulation of NPY mRNA and neuropeptide Y2 receptor(NPY2R) mRNA and the downregulation of GHRL protein and mRNA in the hypothalamus, and the increased expression of NPY and NPY2R as well as the decreased expression of GHRL in the arcuate nucleus (ARC) can be rescued by EA. But, surprisingly, SA seem to make no difference to the levels of FBG and insulin, and the protein expression of ghrelin in the hypothalamus and ARC. Co-expression of kisspeptin and GHSR, and co-expression of gonadotrophin releasing hormone(GnRH) and NPY2R were observed in ARC. No differences were found between groups in protein of GAL, GALP and GHRL expression in the pancreas. Neither EA nor SA can attenuate the upregulated kisspeptin protein expression in the pancreas of PCOS model rats. CONCLUSIONS: EA and SA improved the symptoms of pubertal PCOS rats, and the mechanism might be associated with regulating hypothalamic NPY and ghrelin levels.

Objective:To compare the prognosis of patients with unilateral sporadic medullary thyroid carcinoma treated by different surgical selection, and analyze the independent risk factors affecting the prognosis.Methods:One hundred and twenty-six patients at Tianjin Medical University Cancer Institute and Hospital from Feb 2011 to Oct 2018 were retrospectively divided into group A (total thyroiclectomy) and group B (unilateral lobectomy).Results:There were no significant differences in postoperative recurrence rate ( χ2=0.394, P=0.530), mortality ( χ2=3.175, P=0.146), biochemical cure rate ( χ2=0.613, P=0.434), progression free survival and overall survival ( P=0.278, 0.175) between group A and group B; Tumor diameter ≥4 cm and lateral cervical lymph node metastasis were independent risk factors affecting the overall survival. The incidence of postoperative temporary hypocalcemia ( χ2=5.068, P=0.024) and permanent hypocalcemia ( χ2=6.590, P=0.010) in group A was higher than that in group B. Conclusions:Ipsolateral thyroidectomy can be applied to patients with unilateral sporadic medullary thyroid carcinoma with similar long term prognosis and tower incidence of temporary hypocalcemia and permanent hypocalcemia compared to total thyroidectomy.

Preliminary study of prenatal ultrasound in predicting delivery mode of full-term primipara / 中华超声影像学杂志

Objective:To explore the feasibility of prenatal ultrasound in predicting delivery mode of full-term primipara.Methods:The study prospectively enrolled primiparas with gestational age ≥37 weeks, singleton, cephalic and no contraindications to vaginal delivery who underwent routine prenatal examination in the Third Affiliated Hospital of Sun Yat-sen University from September 2020 to February 2021.In addition to routine fetal ultrasound examination, the transperineal ultrasound examination was performed to assess the angle of progression (AOP), head perineum distance (HPD), the angle of pubic arch and the anteroposterior diameter, left and right diameter, area and perimeter of levator ani hiatus of pregnant women in different states were measured; Cervical length (CL) was examined by transvaginal ultrasound. The delivery mode was tracked, and the indicators related to natural delivery were screened out. Receiver operating characteristic (ROC) curve was used to evaluate the effectiveness of relevant indicators in predicting natural delivery.Results:A total of 142 cases were included in this study, including 112 cases of natural delivery and 30 cases of manual intervention delivery. There were no significant differences in age, gestational weeks, biparietal diameter, head circumference, body mass index (BMI) and neonatal weight between the natural delivery group and the manual intervention delivery group (all P>0.05). Multivariate regression analysis showed that AOP was associated with natural delivery( OR=1.048, P=0.008). ROC curve analysis showed that the area under the curve was 0.648 with AOP 96.92° as the node, and the specificity and positive predictive values were 83.33% and 0.909 1 respectively. Conclusions:It is feasible to predict the mode of delivery by prenatal ultrasound in full-term primiparas. AOP is related to the mode of delivery, which can provide more reference information for clinical practice.

Of 231 THCs which participated in the communities, 95. 2％ joined in countywide medical communities, and 28. 6％ participated in other forms of medical alliances. Conclusions THCs showed high organizational convergence in their participation, and adopted diversified strategies of participation in medical alliance.

Policy analysis for countywide medical communities in the policy model of G. C. Edwards / 中华医院管理杂志

The policy model of G. C. Edwards was used to study the policies on building a countywide medical community ( CMC), and identify problems in such aspects as policy communication, resources, disposition and bureaucratic structure. The analysis found that enriching health resources at primary level and powerful government support are creating ideal environment for the construction of CMC. But due to its preliminary development, rooms of improvement of its policy design, and unclear enforcement standards, there appear behavioral polarizations at local health authorities. For example, some are proactive to explore and accumulate rich experiences, while the most take a wait and see stand, or even take administrative means to cope with their authorities by forming medical communities in form only. A small part of county hospitals, thanks to support from the government and inherent conditions, take active measures in this direction as policy frontrunners. On the other hand, most county hospitals prefer to be policy followers in order to avoid cost and risks of the reform. In the worst cases, a few county hospitals have become free riders of the policy, and attempt to take advantages of their primary health institutions. Primary health institutions warmly embrace CMC, but their limited service capability constitutes roadblocks in CMC construction. What is more, poor communication and collaboration mechanisms among systems and authorities hinder the effective policy synergy and health service integration of CMS.
