Papillary thyroid carcinoma (PTC) is one of the most common tumors of the thyroid gland. The common risk factors of PTC include ionizing radiation, positive family history, and thyroid nodular disease. PTC was identified in Europeans by conducting a genome-wide association study, and a strong association signal with PTC was observed in rs944289 and NKX2-1 (located at the 14q13.3 locus), which was probably the genetic risk factor of PTC. This study aimed to examine the association of this gene with PTC in Chinese. A total of 354 patients with PTC and 360 healthy control subjects from the Han population of Northern China were recruited in the study. These individuals were genotyped to determine rs12589672, rs12894724, rs2076751, and rs944289. The association of rs944289 with PTC was obtained (C vs. T, P=0.027, OR=1.264, 95% CI=1.026-1.557; and C/C-C/T vs. T/T, P=0.034, OR=1.474, 95% CI=1.028-2.112). Conducting a subgroup analysis, we found a marginal difference in the allele frequency distribution of rs944289 (adjusted P=0.062) between the patients with PTC and multi-nodular goiter and the control subjects. We also observed an interaction (P=0.029; OR=2.578, 95% CI=1.104-6.023) between rs944289 and diabetes in patients with PTC. In conclusion, rs944289 was associated with an increased risk of PTC in the Han population of Northern China, but no clear association was observed in either of the tag single nucleotide polymorphisms of NKX2-1.

Thyroid-associated orbitopathy (TAO) is an inflammatory autoimmune disorder. The most serious complication of TAO is dysthyroid optic neuropathy (DON), which can lead to permanent vision loss because of volume expansion in the orbital apex. Orbital radiation therapy (ORT) is an anti-inflammatory treatment used in the treatment of active TAO. Clinical studies support radiotherapy as having a modest effect on DON, and early radiotherapy may protect against disease progression to DON. Current studies suggest that radiotherapy is generally safe. However, risks still exist in some cases. The possible effects of radiotherapy on TAO, especially complicated with DON, are reviewed. The effects of radiotherapy on DON are not completely known, and evidence from standardized, prospective, and multicenter clinical trials is still lacking.

Hypoxia is a common phenomenon in hepatocellular carcinoma (HCC). Hypoxia stabilizes transcription factor, hypoxia-inducible factor (HIF), to activate gene transcription. Expression of HIF is closely associated with metastasis and poor prognosis in HCC. HIF mediates expression of genes that are involved in every step of HCC metastasis including epithelial-mesenchymal transition, invasion of the extracellular matrix, intravasation, extravasation, and secondar y growth of the metastases. Because HIF is the central regulator of HCC metastasis, HIF inhibitors are attractive tools when used alone or as combined treatment to curb HCC metastasis. This review will summarize the current findings on the impact of hypoxia/HIF in HCC, with a particular focus on cancer metastasis.

This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of children with idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormone therapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lower FT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroup was treated with L-T4 (0.5–3.0 g/(kg·d)) from the beginning of the study, and the non-L-T4-treated subgroup received placebo. We also selected 39 ISS children with FT4 in the upper two-thirds of the normal range as the higher FT4 group. During the first year, the lower FT4 group featured lower FT3, FT4, thyroid stimulating hormone (TSH), and insulin-like growth factor-I standard deviation score (IGF-I SDS) and significantly lower height velocity (HV) compared with the higher FT4 group. However, in the lower FT4 group, the L-T4-treated subgroup presented higher FT4, FT3, TSH, and IGF-I SDS concentrations and significantly higher HV compared with children in the non-L-T4-treated subgroup. In children with ISS, the negative effect of thyroid hormone deficiency on growth rate should be considered when FT4 level lies in the low-normal range prior to recombinant human growth hormone treatment.

In this review, we summarize the novel findings from our series of studies on the leading metastasis-related gene, osteopontin (OPN). In our previous gene expression profiling study, OPN was identified as one of the leading genes associated with the metastasis of hepatocellular carcinoma (HCC). We focused on OPN to evaluate its prognostic values and important roles in HCC metastasis. A retrospective study of large cohorts of HCC patients demonstrated that plasma OPN level was one of the leading independent prognostic factors for HCC patients, even in the early stage of HCC, and could serve as a surrogate serologic biomarker for monitoring the treatment response and tumor recurrence after HCC resection. Using both in vitro and in vivoinvestigations, we found that OPN has an important role in metastasis and tumor growth of HCC and is an attractive potential therapeutic target for combating HCC metastasis. We also found that OPN+ HCC cells have much more amplifications at chromosomal regions, and promoter polymorphisms are important in the regulation of OPN expression and tumor growth and lung metastasis of HCC.

Hepatocellular carcinoma (HCC) is currently the fifth most common malignancy and the third leading cause of cancer-related mortalities worldwide. In the last few years, treatments for HCC have significantly improved from a mere surgical resection to a series of minimally invasive therapies and targeted drugs. However, recurrence frequently occurs even upon curative therapeutics, and drug therapies generally produce disappointing results, with the overall prognosis dismal. This challenging clinical scenario warrants new effective and life-prolonging strategies for patients with HCC. Compelling evidence suggests that NK cells play a critical role in the immune function of the liver and in the immune defenses against HCC, indicating that HCC might be an ideal target for NK cell-based immunotherapies. To obtain comprehensive insights into the putative influence of NK cells on HCC, this paper summarizes current knowledge on NK cells in HCC and discusses the usefulness and prospects of NK cell-based immunotherapies. Critical issues that require consideration for the successful clinical translation of NK cell-based therapies are also addressed. If appropriately used and further optimized, NK cell-based therapies could dominate important roles in the future immunotherapeutic market of HCC.

Primary hepatic carcinoma (PHC) is a common malignant tumor in China. Cancer is comprehensively treated with various therapeutic regimes, including traditional Chinese medicine (TCM). TCM has been widely used to improve the quality of life, delay the time of cancer progression, and prolong the median survival time. This systematic review with meta-analysis aimed to assess the effect of TCM combined with Western therapy on primary hepatic carcinoma. A comprehensive literature search was conducted in six databases, including CNKI, VIP, Wan-Fang Database, CBM, PubMed, and Cochrane library. A total of 44 randomized controlled trials (RCTs) involving 3429 participants suffering from PHC were selected. Meta-analysis results indicated that the overall effect of TCM and Western integrative treatment on PHC was higher than that of Western intervention alone, which can postpone tumor recurrence and metastasis and prolong the overall survival time of patients with PHC. Although the obtained evidence remained weak because of the poor methodological quality of the included studies, this review provided relevant data supporting the efficacy and safety of TCM combined with Western therapies. In future research, individual RCT studies should incorporate accepted standards for trial design and reporting, proper outcome indicators according to international standards, blinding in allocation concealment, and valid follow-up periods.

We performed weighted gene coexpression network analysis (WGCNA) to gain insights into the molecular aspects of hepatocellular carcinoma (HCC). Raw microarray datasets (including 488 samples) were downloaded from the Gene Expression Omnibus (GEO) website. Data were normalized using the RMA algorithm. We utilized the WGCNA to identify the coexpressed genes (modules) after non-specific filtering. Correlation and survival analyses were conducted using the modules, and gene ontology (GO) enrichment was applied to explore the possible mechanisms. Eight distinct modules were identified by the WGCNA. Pink and red modules were associated with liver function, whereas turquoise and black modules were inversely correlated with tumor staging. Poor outcomes were found in the low expression group in the turquoise module and in the high expression group in the red module. In addition, GO enrichment analysis suggested that inflammation, immune, virus-related, and interferon-mediated pathways were enriched in the turquoise module. Several potential biomarkers, such as cyclin-dependent kinase 1 (CDK1), topoisomerase 2α (TOP2A), and serpin peptidase inhibitor clade C (antithrombin) member 1 (SERPINC1), were also identified. In conclusion, gene signatures identified from the genome-based assays could contribute to HCC stratification. WGCNA was able to identify significant groups of genes associated with cancer prognosis.

研究表明微生态失调在多种肿瘤的发生发展中起至关重要的作用。然而,对于甲状腺肿瘤中细菌是否参与肿瘤的发生仍不清楚。本研究中,我们旨在探索甲状腺组织中的菌群特征及其对甲状腺乳头状癌(PTC)的作用。我们同时对 340 例PTC和甲状腺良性结节 (BTN) 患者的肿瘤组织及其邻近正常组织进行菌群分析和转录组测序。在PTC、BTN及其邻近无肿瘤组织中鉴定出明显不同的菌群特征。我们通过免疫组化染色、细菌原位杂交和电镜观察验证了甲状腺组织内细菌的存在。与BTN相比,我们发现在PTC中有17个菌属存在显著丰度差异,其中PTC中富集菌Rhodococcus、Neisseria、Streptococcus、Halomonas和Devosia存在促癌作用;以及丰度降低的Amycolatopsis则可能有抑癌作用。这些丰度存在明显差异的细菌可以鉴别PTC组织(PTC-T)与BTN组织(BTN-T),曲线下面积(AUC)为81.66%。微生物网络分析表明,PTC组织内细菌间的相互关联性高于BTN组织。同时,在合并桥本甲状腺炎组织的PTC中发现与免疫相关的菌属(Erwinia、Bacillus 和 Acinetobacter)明显富集。此外,我们联合转录组测序分析提示PTC富集菌与肿瘤相关信号通路的关键基因如BRAF、KRAS、IRAK4、CTNNB1、PIK3CA、MAP3K7 和 EGFR存在正相关性。总的来说,我们的研究结果表明,甲状腺肿瘤组织内存在菌群失调,并可能通过肿瘤相关信号通路参与PTC的发生。
