RESUMO
OBJECTIVE: To determine the accuracy of uterine corpus invasion (UCI) diagnosis in patients with cervical cancer and identity risk factors for UCI and depth of invasion. METHODS: Clinical data of patients with cervical cancer who underwent hysterectomy between 2004 and 2016 were retrospectively reviewed. UCI was assessed on uterine pathology. Independent risk factors for UCI and depth of invasion were identified using binary and ordinal logistic regression models, respectively. RESULTS: A total of 2,212 patients with cervical cancer from 11 medical institutions in China were included in this study. Of these, 497 patients had cervical cancer and UCI, and 1,715 patients had cervical cancer and no UCI, according to the original pathology reports. Retrospective review of the original pathology reports revealed a missed diagnosis of UCI in 54 (10.5%) patients and a misdiagnosis in 36 (2.1%) patients. Therefore, 515 patients with cervical cancer and UCI (160 patients with endometrial invasion, 176 patients with myometrial invasion < 50%, and 179 patients with myometrial invasion ≥ 50%), and 1697 patients with cervical cancer without UCI were included in the analysis. Older age, advanced stage, tumor size, adenocarcinoma, parametrial involvement, resection margin involvement, and lymph node metastasis were independent risk factors for UCI. These risk factors, except resection margin involvement, were independently associated with depth of UCI. CONCLUSIONS: UCI may be missed or misdiagnosed in patients with cervical cancer on postoperative pathological examination. Older age, advanced stage, tumor size, adenocarcinoma, parametrial involvement, resection margin involvement, and lymph node metastasis were independent risk factors for UCI and depth of UCI, with the exception of resection margin involvement.

Thyroid cancer has long been considered to arise in middle age and progress to more aggressive and lethal cancers after its repeated proliferation. In this research, we aimed at investigating the biological function and the underlying molecular mechanism of Melanoregulin (MREG) in thyroid cancer. It was found that the expression of MREG was significantly downregulated in thyroid cancer tissues. The downregulation of MREG expression was caused by epigenetic methylation. MREG overexpression could suppress the invasion and proliferation of thyroid cancer cells. While MREG knockdown promoted the invasion and proliferation of thyroid cancer cells. Furthermore, the phosphorylation of Akt or mTOR was decreased by MREG overexpression and increased by MREG knockdown. Moreover, Dactolisib (the inhibitor of mTOR) could abrogate silenced MREG induced thyroid cancer cell invasion and proliferation. Taken together, MREG regulates thyroid cancer cell invasion and proliferation through PI3K/Akt-mTOR signaling pathway. MREG may serve as a promising therapeutic strategy for thyroid cancer.

Traditional packaging materials feed the growing global food protection. However, these packaging materials are not conducive to environment and have not the ability to kill bacteria. Herein, a green and simple strategy is reported for food packaging protection and long-term antibacterial using carboxymethylcellulose-based photothermal film (CMC@CuS NPs/PVA) that consists of carboxymethyl cellulose (CMC) immobilized copper sulfide nanoparticles (CuS NPs) and polyvinyl alcohol (PVA). With satisfied oxygen transmittance (0.03 cc/m2/day) and water vapor transmittance (163.3 g/m2/day), the tensile strength, tear strength and burst strength reached to 3401.2 N/m, 845.7 mN and 363.6 kPa, respectively, which could lift 4.5 L of water. The composite film had excellent photothermal conversion efficiency and photothermal stability. Under the irradiation of near infrared (NIR), it can rapidly heated up to 197 °C within 25 s. The antibacterial analysis showed that the inhibition rate of composite film against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) could all reach >99 %. Furthermore, the synthesized CuS NPs was well immobilized and the residual rate of copper kept 98.7 % after 10 days. Noticeably, the composite film can preserve freshness of strawberries for up to 6 days. Therefore, the composite film has potential application for food antibacterial protection.

PURPOSE: To develop and validate a deep learning-based pathological risk score (RS) with an aim of predicting patients' prognosis to investigate the potential association between the information within the whole slide image (WSI) and cervical cancer prognosis. METHODS: A total of 251 patients with the International Federation of Gynecology and Obstetrics (FIGO) Stage IA1-IIA2 cervical cancer who underwent surgery without any preoperative treatment were enrolled in this study. Both the clinical characteristics and WSI of each patient were collected. To construct a prognosis-associate RS, high-dimensional pathological features were extracted using a convolutional neural network with an autoencoder. With the score threshold selected by X-tile, Kaplan-Meier survival analysis was applied to verify the prediction performance of RS in overall survival (OS) and disease-free survival (DFS) in both the training and testing datasets, as well as different clinical subgroups. RESULTS: For the OS and DFS prediction in the testing cohort, RS showed a Harrell's concordance index of higher than 0.700, while the areas under the curve (AUC) achieved up to 0.800 in the same cohort. Furthermore, Kaplan-Meier survival analysis demonstrated that RS was a potential prognostic factor, even in different datasets or subgroups. It could further distinguish the survival differences after clinicopathological risk stratification. CONCLUSION: In the present study, we developed an effective signature in cervical cancer for prognosis prediction and patients' stratification in OS and DFS.

Objective: This study aimed to compare the survival outcomes among stage IB3 cervical cancer patients who undergo abdominal radical hysterectomy (ARH)+pelvic lymphadenectomy ± para-aortic lymph node dissection versus radiochemotherapy (R-CT). Methods: Based on the large number of diagnoses and treatments for cervical cancer in the Chinese database, propensity score matching (PSM) was used to compare the 5-year overall survival (OS) and disease-free survival (DFS) rates of the ARH group and R-CT group. Results: There were 590 patients with stage IB3 cervical cancer according to the FIGO 2018 staging system, with 470 patients in the ARH group and 120 patients in the R-CT group. The ARH and R-CT groups showed different 5-year OS and DFS rates in the total study population, and the 5-year OS and DFS rates in the R-CT group (n = 120) were lower than those in the ARH group (n = 470) (OS: 78.1% vs. 92.1%, p < 0.001; DFS: 71.6% vs. 90.3%, p < 0.001). R-CT was associated with a worse 5-year OS rate (hazard ratio [HR] = 3.401; 95% confidence interval [CI] = 1.875-6.167; p < 0.001) and DFS rate (HR = 3.440; 95% CI = 2.075-5.703; p < 0.001) by Cox multivariate analysis. After 1:3 PSM, the 5-year OS and DFS rates in the R-CT group (n = 108) were lower than those in the RH group (n = 280) (OS: 76.4% vs. 94.0%, p < 0.001; DFS: 69.3% vs. 92.6%, p < 0.001, respectively). R-CT was associated with a worse 5-year OS rate (HR = 4.071; 95% CI = 2.042-8.117; p < 0.001) and DFS rate (HR = 4.450; 95% CI = 2.441-8.113; p < 0.001) by Cox multivariate analysis. Conclusion: Our study found that for FIGO 2018 stage IB3 cervical cancer patients, ARH resulted in better OS and DFS than R-CT.
RESUMO
Objective: To compare the 3-year oncological outcomes of robot-assisted radical hysterectomy (RRH) and abdominal radical hysterectomy (ARH) for cervical cancer. Methods: Based on the clinical diagnosis and treatment for cervical cancer in the China database, patients with FIGO 2018 stage IA with lymphovascular space invasion (LVSI)-IB2 cervical cancer disease who underwent RRH and ARH from 2004 to 2018 were included. Kaplan-Meier survival analysis was used to compare the 3-year overall survival (OS) and disease-free survival (DFS) rate between patients receiving RRH and those receiving ARH. The Cox proportional hazards model and propensity score matching were used to estimate the surgical approach-specific survival. Results: A total of 1,137 patients with cervical cancer were enrolled in this study, including the RRH group (n = 468) and the ARH group (n = 669). The median follow-up time was 45 months (RRH group vs. ARH group: 24 vs. 60 months). Among the overall study population, there was no significant difference in 3-year OS and DFS between the RRH group and the ARH group (OS: 95.8% vs. 97.6% p = 0.244). The Cox proportional hazards analysis showed that RRH was not an independent risk factor for 3-year OS (HR: 1.394, 95% CI: 0.552-3.523, p = 0.482). However, RRH was an independent risk factor for 3-year DFS (HR: 1.985, 95% CI: 1.078-3.655 p = 0.028). After 1:1 propensity score matching, there was no significant difference in 3-year OS between the RRH group and the ARH group (96.6% vs. 98.0%, p = 0.470); however, the 3-year DFS of the RRH group was lower than that of the ARH group (91.0% vs. 96.1%, p = 0.025). The Cox proportional hazards analysis revealed that RRH was not an independent risk factor for 3-year OS (HR: 1.622, 95% CI: 0.449-5.860 p = 0.461), but RRH was an independent risk factor for 3-year DFS (HR: 2.498, 95% CI: 1.123-5.557 p = 0.025). Conclusion: Among patients with stage I A1 (LVSI +)-I B2 cervical cancer based on the FIGO 2018 staging system, RRH has a lower 3-year DFS than ARH, suggesting that RRH may not be suitable for early cervical cancer patients.
RESUMO
The clinical features of 426 pituitary adenomas were retrospectively analyzed, focusing on the factors that affect the development of pituitary apoplexy. Immunohistochemical analysis was used to define the different hormone types of the tumors and the expression of various immunologic targets, including the pituitary tumor transforming gene, basic fibroblast growth factor-2, matrix metalloproteinase-9, tissue inhibitor of metalloproteinase-1, and proliferating cell nuclear antigen. Of the 426 patients, 83 presented with pituitary apoplexy (19.48%). Among them, 43 patients (43/83, 51.82%) developed apoplexy in the absence of any obvious precipitating factor. Clinical manifestations included headaches (80/83, 96.38%), vision loss (69/83, 83.13%), pituitary function change (51/83, 61.45%), visual field defects (41/83, 49.39%), and nausea and vomiting (34/83, 40.96%). Male patients and patients with functional adenoma had a higher probability of developing apoplexy. Complicated immunological expression patterns were found in adenomas associated with pituitary apoplexy, with adenomas of different hormone types identified.

BACKGROUND: The efficacy of therapy for cervical cancer is related to the alteration of multiple molecular events and signaling networks during treatment. The aim of this study was to evaluate gene expression alterations in advanced cervical cancers before- and after-trans-uterine arterial chemoembolization- (TUACE). METHODS: Gene expression patterns in three squamous cell cervical cancers before- and after-TUACE were determined using microarray technique. Changes in AKAP12 and CA9 genes following TUACE were validated by quantitative real-time PCR. RESULTS: Unsupervised cluster analysis revealed that the after-TUACE samples clustered together, which were separated from the before-TUACE samples. Using a 2-fold threshold, we identified 1131 differentially expressed genes that clearly discriminate after-TUACE tumors from before-TUACE tumors, including 209 up-regulated genes and 922 down-regulated genes. Pathway analysis suggests these genes represent diverse functional categories. Results from real-time PCR confirmed the expression changes detected by microarray. CONCLUSIONS: Gene expression signature significantly changes during TUACE therapy of cervical cancer. Theses alterations provide useful information for the development of novel treatment strategies for cervical cancers on the molecular level.

Endometrial cancer is a common gynecological malignancy in developed countries. Insulin has been identified as a risk factor for endometrial cancer. However, whether insulin levels are related to the risk of lymph node metastasis (LNM) in endometrial cancer is unknown. We conducted a prospective cohort study in a regional hospital to examine the relationships between insulin levels and risk of LNM in premenopausal and postmenopausal women. A total of 668 patients were recruited. Of these, 206 were premenopausal (mean age: 42.01 ± 10.17) and 462 were postmenopausal (mean age: 62.13 ± 13.85). The incidence of LNM in both premenopausal and postmenopausal groups was comparable at 7% and 8%, respectively. In premenopausal women, multivariate logistic regression demonstrated that insulin levels (OR: 2.11, 95% CI: 1.48-2.85, P < 0.05) were significant predictors of LNM risk. In the same group, insulin levels remained significant predictors of LNM risk (cut-off: 10.48 µIU/mL) when adjusted for body mass index (BMI) (OR: 3.51, 95% CI: 1.42-5.98; P < 0.05) or for waist-to-hip ratio (WHR) (OR: 1.87, 95% CI: 1.08-2.66; P < 0.05). Similarly, in postmenopausal women, multivariate logistic regression showed that insulin levels (OR: 1.99, 95% CI: 1.30-2.89; P < 0.05) also significantly predicted LNM risk. This relationship was maintained even after adjustment for BMI (cut-off: 7.40 µIU/mL, OR: 1.99, 95% CI: 1.01-3.12, P < 0.05) or for WHR (cut-off: 10.15 µIU/mL, OR: 1.61, 95% CI: 1.04-2.35; P < 0.05). Insulin levels are significantly associated with LNM risk in both premenopausal and postmenopausal women with endometrial cancer. Further prospective studies are needed to examine a potential causal relationship and determine whether its use can offer incremental value for risk stratification in this patient population.

Cervical cancer is a cause of cancer death, making it one of the most common causes of death among women globally. Previously, a variety of studies have revealed the molecular mechanisms by which cervical cancer develops. However, there are still limitations in treatment for cervical cancer. Ursolic acid is a naturally derived pentacyclic triterpene acid, exhibiting broad anticancer effects. Nanoparticulate drug delivery systems have been known to better the bioavailability of drugs on intranasal administration compared with only drug solutions. Administration of ursolic acid nanoparticles is thought to be sufficient to lead to considerable suppression of cervical cancer progression. We loaded gold-ursolic acid into poly(DL-lactide-co-glycolide) nanoparticles to cervical cancer cell lines due to the properties of ursolic acid in altering cellular processes and the easier absorbance of nanoparticles. In addition, in this study, ursolic acid nanoparticles were administered to cervical cancer cells to find effective treatments for cervical cancer inhibition. In the present study, ELISA, western blotting, flow cytometry and immunohistochemistry assays were carried out to calculate the molecular mechanism by which ursolic acid nanoparticles modulated cervical cancer progression. Data indicated that ursolic acid nanoparticles, indeed, significantly suppress cervial cancer cell proliferation, invasion and migration compared to the control group, and apoptosis was induced by ursolic acid nanoparticles in cervical cancer cells through activating caspases, p53 and suppressing anti-apoptosis-related signals. Furthermore, tumor size was reduced by treatment of ursolic acid nanoparticles in in vivo experiments. In conclusion, this study suggests that ursolic acid nanoparticles inhibited cervical cancer cell proliferation via apoptosis induction, which could be a potential target for future therapeutic strategy clinically.

AIM: To examine the expression of survivin mRNA in cervical squamous cancer at different time points during interventional therapy in order to find the optimal time point for continual treatment. PATIENTS AND METHODS: Fifty patients with stage IB2-IIB cervical squamous cancer receiving transarterial infusion chemotherapy and chemoembolization were included in the present study. The expression of survivin mRNA in cancer samples before and after interventional therapy (on days 7, 14 and 21) were examined by reverse transcription-polymerase chain reaction. RESULTS: The expression of survivin mRNA in cancer samples before the interventional therapy was significantly higher than that of any time point after the interventional therapy (p<0.05). After treatment, the expression of survivin mRNA decreased until day 14. CONCLUSION: The expression of survivin mRNA was inhibited by the interventional therapy. It seems that day 14 after interventional treatment is the right time point for continuation of treatment.

The m6A mRNA methylation involves in mRNA splicing, degradation and translation. Recent studies have revealed that reduced m6A mRNA methylation might promote cancer development. However, the role of m6A mRNA methylation in cervical cancer development remains unknown. Therefore, we investigated the role of m6A methylation in cervical cancer in the current study. We first evaluated the m6A mRNA methylation level in 286 pairs of cervical cancer samples and their adjacent normal tissues by dot blot assay. Then the role of m6A on patient survival rates and cervical cancer progression were assessed. The m6A level was significantly reduced in the cervical cancer when comparing with the adjacent normal tissue. The m6A level reduction was significantly correlated with the FIGO stage, tumor size, differentiation, lymph invasion and cancer recurrence. It was also shown to be an independent prognostic indicator of disease-free survival and overall survival for patients with cervical cancer. Reducing m6A level via manipulating the m6A regulators expression promoted cervical cancer cell proliferation. And increasing m6A level significantly suppressed tumor development both in vitro and in vivo. Our results showed that the reduced m6A level is tightly associated with cervical cancer development and m6A mRNA methylation might be a potential therapeutic target in cervical cancer.
RESUMO
Bone morphogenetic protein 4 (BMP-4) is a member of the BMP protein family. BMP-4 was reported to induce epithelial-mesenchymal transition (EMT) and promote tumor cell immigration and invasion. This study aimed to investigate the expression of BMP-4 in papillary thyroid carcinoma (PTC) and its correlation with the patients' clinicophathological features and with tumor invasion and metastasis. Surgically resected PTC specimens from 82 patients admitted to the Department of Thyroid Surgery of Yantai Yuhuangding Hospital between Feb 1st and May 31st, 2016 were collected. The expression level of BMP-4 in PTC tissues was examined by immunohistochemical staining. The full clinical records of all patients were collected to analyze the relevance between BMP-4 expression and the clinical pathological features of PTC. Our result showed that BMP-4-positive cell rate and staining intensity were positively correlated with the patient's age (P=0.031, 0.037), tumor size (P=0.033, 0.019), capsular invasion (P=0.001, 0.002) and TNM stage (P=0.001, 0.004), while not correlated with gender, multicentricity of tumor or lymphatic metastasis. In conclusion, this study identified BMP-4 as a potential molecular marker for predicting the invasion and progression of PTC.

OBJECTIVE: To evaluate the safety and efficacy of uterine artery embolization (UAE) for the treatment of adenomyosis. METHODS: A prospective study was performed at Yuhuangding Hospital, China, between January 2012 and December 2013, enrolling premenopausal patients diagnosed with adenomyosis. All patients were treated with bilateral UAE using 500-700-µm tris-acryl gelatin microspheres. At baseline, and 3, 6, and 12months after UAE, magnetic resonance imaging was used to assess uterine volume and patient-assessed improvements in dysmenorrhea were recorded. Any complications and adverse events were reported. RESULTS: In total, 117 patients with adenomyosis were enrolled. The bilateral UAE procedure was successful in 115 (98.3%) patients, who were able to return to normal activity within 1week of treatment. At 12-month follow-up, a median 51.0% reduction in uterine volume from baseline was recorded (P=0.005). Marked and moderate improvements in dysmenorrhea symptoms were reported by 64 (55.7%) and 31 (27.0%) participants, respectively. Pelvic pain of varying intensity was reported by 112 (97.4%) patients but was managed with analgesia. Persistent amenorrhea was experienced by 2 (1.7%) individuals following treatment. Patients did not encounter any new gynecologic or general complications following UAE treatment. CONCLUSION: UAE could be considered as a minimally invasive treatment option for patients with adenomyosis. Further research to compare the efficacy and safety of UAE with conventional hysterectomy is warranted.
