Severe Pain and Postoperative Effects during Hysterosalpingography: A Meta-Analysis.

Background: We aimed to evaluate the impact of pain on patients during Hysterosalpingography (HSG). Methods: PubMed, PMC and other journals were searched for randomized controlled trials (RCTS) on HSG. Appropriate articles were selected for inclusion and reasonable exclusion according to keywords. Following a thorough review of the relevant literature, the process of literature screening was conducted in accordance with the aforementioned criteria. The methodological quality of the studies was assessed using the risk of bias assessment tool developed by the Cochrane Collaboration. Meta-analysis was conducted using RevMan 5.4.1 software. Results: Twelve studies were included, including 1530 cases in the experimental group and 1545 cases in the control group. The literature summarizes the basic information of patients during HSG and makes statistics on the differences in visual analog scale (VAS) and pain perception. The findings from the HSG examination revealed a lack of significant association between patients' pain sensation and their age and BMI. However, the duration of pregnancy in patients decreased following HSG treatment (95%CI (-18.84 to -3.58), P=0.004).Compared with conventional testing, HSG could effectively reduce the pregnancy time of patients (95%CI (-18.84, -3.58), P=0.004), reduce the VAS of patients (95%CI (-4.73, -1.51), P=0.0001), and increase the number of patients without pain (95%CI (1.80, 10.43), P=0.001). Conclusion: During the HSG examination, acceptable pain avoidance is generated and can be relieved over time. At present, there is no effective alternative method, so the patient should cooperate with the doctor to complete the examination, to relieve the pain.

Identification of VEGFs-related gene signature for predicting microangiogenesis and hepatocellular carcinoma prognosis.

Microangiogenesis is an important prognostic factor in various cancers, including hepatocellular carcinoma (HCC). The Vascular Endothelial Growth Factor (VEGF) has been shown to contribute to tumor angiogenesis. Recently, several studies have investigated the regulation of VEGF production by a single gene, with few researchers exploring all genes that affect VEGF production. In this study, we comprehensively analyzed all genes affecting VEGF production in HCC and developed a risk model and gene-based risk score based on VEGF production. Moreover, the model's predictive capacity on prognosis of HCCs was verified using training and validation datasets. The developed model showed good prediction of the overall survival rate. Patients with a higher risk score experienced poor outcomes compared to those with a lower risk score. Furthermore, we identified the immunological causes of the poor prognosis of patients with high-risk scores comparing with those with low-risk scores.

The potential of 18F-FDG PET/CT metabolic parameter-based nomogram in predicting the microvascular invasion of hepatocellular carcinoma before liver transplantation.

PURPOSE: Microvascular invasion (MVI) is a critical factor in predicting the recurrence and prognosis of hepatocellular carcinoma (HCC) after liver transplantation (LT). However, there is a lack of reliable preoperative predictors for MVI. The purpose of this study is to evaluate the potential of an 18F-FDG PET/CT-based nomogram in predicting MVI before LT for HCC. METHODS: 83 HCC patients who obtained 18F-FDG PET/CT before LT were included in this retrospective research. To determine the parameters connected to MVI and to create a nomogram for MVI prediction, respectively, Logistic and Cox regression models were applied. Analyses of the calibration curve and receiver operating characteristic (ROC) curves were used to assess the model's capability to differentiate between clinical factors and metabolic data from PET/CT images. RESULTS: Among the 83 patients analyzed, 41% were diagnosed with histologic MVI. Multivariate logistic regression analysis revealed that Child-Pugh stage, alpha-fetoprotein, number of tumors, CT Dmax, and Tumor-to-normal liver uptake ratio (TLR) were significant predictors of MVI. A nomogram was constructed using these predictors, which demonstrated strong calibration with a close agreement between predicted and actual MVI probabilities. The nomogram also showed excellent differentiation with an AUC of 0.965 (95% CI 0.925-1.000). CONCLUSION: The nomogram based on 18F-FDG PET/CT metabolic characteristics is a reliable preoperative imaging biomarker for predicting MVI in HCC patients before undergoing LT. It has demonstrated excellent efficacy and high clinical applicability.

hsa_circ_0051428 Facilitates the Progression of Thyroid Cancer by Sponging miR-1248 to Up-Regulate FN1.

Evidence displays that circular RNAs (circRNAs) are considerable mediators of numerous processes in cancer development. Given that many circRNAs are not functionally characterized, our aim was to explore the function and mechanisms of circ_0051428 in thyroid cancer (TC). The analysis of circ_0051428, miR-1248 and FN1 mRNA expression was conducted using real-time quantitative polymerase chain reaction. Cell growth was observed using CCK-8 and colony formation assays. Cell migration was investigated using wound healing assay. Cell apoptosis was identified by the expression of apoptosis-related proteins (Bax and Bcl-2) using Western blotting. Animal models were established to testify the role of circ_0051428 in vivo. The assumed binding between miR-1248 and circ_0051428 or FN1 was identified using dual-luciferase reporter or RIP assay. circ_0051428 exhibits an abnormally elevated expression in TC. circ_0051428 deficiency caused inhibition of TC cell proliferation, migration, clonogenic capacity, and inhibition of tumor growth in vivo. circ_0051428 directly targeted miR-1248, and FN1 was a target downstream of circ_0051428/miR-1248 axis. circ_0051428 could sponge miR-1248 to upregulate FN1. Furthermore, miR-1248 downregulation recovered circ_0051428 deficiency-suppressed cancer cell proliferation, survival and migration. Besides, the repressive effects of FN1 knockdown on cancer cell growth, survival and migration were also partly abolished by miR-1248 downregulation. circ_0051428 targeted miR-1248 to modulate FN1 expression, thereby facilitating the malignant progression of TC, which contributed to the understanding of the molecular mechanism of TC development.

Radioactive Gold Nanoparticle in Two Forms (19879Au GNPs and 99mTc-GNPs) for Lung Cancer Antiproliferative Induction and Intralesional Imaging: A Proof of Concept.

BACKGROUND: Lung cancer is among the most common cancers worldwide, responsible for 13% of all new cancer cases. Also, it is the leading cause of cancer death among both men and women. In this scenario, an effective and efficient treatment is required. OBJECTIVE: Production of two gold nanoparticles: 198Au and 99mTc-Au. The first one has been produced from irradiation of the 197Au in order to produce a beta-emitter gold nanoparticle for cancer therapy. The second one has been produced from the radiolabeling of gold nanoparticles with technetium 99 metastable in order to produce imaging nanoagent. METHODS: The 198Au nanoparticles were produced by irradiation and identified by hyper-purity germanium (HPGe). They were then evaluated in vitro in order to confirm the behavior on cell proliferation of lung cancer cell lines by the MTT methodology using A549 cells. The 99mTc-Au nanoparticles were produced by directradiolabeling with 99mTc and evaluated in vivo as intralesional nanoagent. RESULTS: The results showed that in both cases, all the nanoparticles have performed their duties with excellence. The 198Au nanoparticles were capable to kill lung cancer cells, while 99mTc-Au was capable to image the tumor after intralesional injection. In addition, 99mTc-Au nanoparticles were useful for biodistribution assay imaging, showing the main organs responsible for the nanoparticle uptake in healthy animals. CONCLUSION: Both gold nanoparticles showed to be a highly efficient nanoagent for both: therapy and diagnosing of lung cancer.

Study of Effect of Sympathetic Nerve on Children's Brain Diseases Based on Analysis of Magnetic Resonance Imaging Kurtosis.

BACKGROUND: We evaluated the improvement in the gray and white matter functional areas in children with cerebral palsy (CP) after common carotid artery sympathetic neural network ablation. We also analyzed the relationship between the values of the diffusion kurtosis imaging (DKI) parameters and clinical signs in children with CP. METHODS: We collected data from 22 children with unilateral spastic CP who had undergone common carotid sympathetic neural network ablation in our hospital from January 1, 2014 to December 1, 2018, using magnetic resonance kurtosis imaging technology parameters. RESULTS: The study found that the changes from preoperatively to postoperatively in the kurtosis fractional anisotropy (KFA) values for the frontal lobe, parietal lobe, temporal lobe, internal sac forelimb, and corpus callosum were statistically significant. However, the changes in the internal sac forelimb, corpus callosum, and KFA values were not statistically significant. The changes from preoperatively to postoperatively in the mean kurtosis (MK) values for the frontal lobe, parietal lobe, temporal lobe, hindlimb of the internal capsule, corpus callosum, and caudate nucleus were statistically significant. However, the MK values for the forelimb, corpus callosum, and thalamus were not statistically significant. The 66-item gross motor function measure scores correlated negatively with the KFA value and positively with the MK value. CONCLUSION: Therefore, it can be concluded that DKI technology can more accurately reflect the gray and white matter damage in children with CP, and the DKI parameters can be used as a monitoring and evaluation index for children with CP.

Ethiodized poppyseed oil versus ioversol for image quality and adverse events in hysterosalpingography: a prospective cohort study.

BACKGROUND: This study aimed to investigate the image quality and adverse events (AEs) of ethiodized poppyseed oil (EPO) compared with ioversol as contrast agents in hysterosalpingography (HSG). METHODS: Two hundred twenty-eight patients underwent HSG were consecutively recruited in this prospective cohort study, and were accordingly divided into EPO group (N = 165) and ioversol group (N = 63). The quality of image was assessed according to the European Guidelines on quality criteria for diagnostic radiographic images. AEs during, within 2 h and at 1-month post-HSG were recorded. RESULTS: EPO displayed elevated image quality compared with ioversol including the total image quality score (P < 0.001), the cervical canal display score (P < 0.001), shape and outline of uterus score (P < 0.01), cervical mucosa or folds score (P < 0.001), oviduct isthmus score (P < 0.001), ampulla and fimbriae of oviduct score (P < 0.001) and celiac diffuse image score (P < 0.001). Multivariate linear regression displayed that EPO (P < 0.001) was an independent predictive factor for increased total image quality score. AEs were similar between EPO group and ioversol group during and within 2 h post-HSG (all P > 0.05). However, at 1-month post-HSG, the number of patients had unchanged and faded menstrual blood color decreased but the proportion of patients with deepened menstrual color increased in EPO group compared with ioversol group (P = 0.007). In addition, the number of patients had iodine residue in uterine cavity was elevated in EPO group compared with ioversol group (P < 0.001). CONCLUSION: EPO is more efficient in image quality and equally tolerant compared to ioversol as contrast agents in HSG.
