Objective To investigate the diagnostic and prognostic values of 18 F?FDG PET/CT in pa?tients with cervical nodal metastases from carcinoma of unknown primary site (CCUP). Methods A total of 137 consecutive patients(95 males, 42 females, age range 24-84 (55.77±11.71) years) with histological proven CCUP who underwent 18 F?FDG PET/CT imaging to find primary tumors from March 2010 to June 2015 were retrospectively analyzed. The gold standard was the final pathological diagnosis or clinical long?term fol?low?up (≥6 months) results. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PET/CT imaging in detecting primary tumors were calculated. Kaplan?Meier anal?ysis was conducted for survival analysis and to identify the presence of any prognostic factors, such as age, gender, presence or absence of distant metastasis, region of involved cervical lymph nodes, left (right)?side/both sides of lymph node involvement, histopathologic tumor type and primary site found or not by PET/CT imaging. Results Primary tumors were confirmed in 96 patients, of which 87 patients were diagnosed correct?ly by 18 F?FDG PET/CT imaging. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 90.6% (87/96), 80.5% (33/41), 87.6% (120/137), 91.6% (87/95) and 78.6% (33/42) respectively. Primary tumors were found most commonly in the head, neck and lung. However, the false positive and negative lesions were also mainly seen in those sites. Distant metastasis and the inferior region of cervical lymph node metastasis were associated with the worst survival (χ2=20. 990 and 12?277, both P<0.01) . The ROC curve revealed that patients with SUVmax>6.5 were of higher mortality risk than those with SUVmax≤6.5 (χ2=7.120, P<0.01) . Conclusions Whole?body 18 F?FDG PET/CT scan is a significant and valuable tool in the identification of the primary tumor site in patients with CCUP . Further? more, according to the distant metastasis and region of cervical lymph nodes metastasis, 18 F?FDG PET/CT scans are of value in prognostic evaluation even if without the need to identify the primary tumors.

OBJECTIVETo evaluate the expression and possible modulation of heme oxygenase-1 (HO-1) in nasal polyps of patients with chronic rhinosinusitis with nasal polyps (CRSwNP).
METHODSNasal polyps and uncinate process tissues were collected from 25 CRSwNP patients and 19 healthy controls with nasal septal deviation. HO-1 expression was examined using qRT-PCR, immunohistochemistric staining and Western blot analysis. Moreover, additional uncinate process mucosal samples of 15 healthy controls with nasal septal deviation were harvested for nasal explant culture experiments. HO-1 expression was measured in cultured nasal explant in response to specific inflammatory and glucocorticoid stimulation. SPSS 20.0 software was used to analyze the data.
RESULTSThe mRNA and protein expression of HO-1 was significantly increased in polyp tissues, 1.220±0.397 in mRNA and 1.409±0.701 in protein, compared with healthy controls 0.464±0.318 in mRNA and 0.017±0.1147 in protein (U=22.00 in mRNA and U=1.00 in protein, both P< 0.05). The immunohistochemical results showed that HO-1 was mainly distributed in the epithelial layer, submucosal glands and inflammatory cells in nasal tissues. Nasal explant culture experiments demonstrated that HO-1 mRNA was upregulated by IL-17A. The HO-1 mRNA level before the stimulation was 1.000, and 17.264±4.275 after the stimulation of 1 ng/ml IL-17A (U=0, P<0.05), 19.128±4.605 after the stimulation of 10 ng/ml IL-17A (U=0, P<0.05), but was significantly suppressed after stimulation with glucocorticoids (dexamethasone, DEX). The mRNA level after the glucocorticoids stimulation was 0.370±0.101 (U=0, P<0.05) and 0.316±0.167 (U=0, P<0.05) respectively. Furthermore, the HO-1 mRNA was inhibited by TGF-β1, the mRNA level was 0.217±0.322 (U=0, P<0.05), 0.070±0.070 (U=0, P<0.05), respectively.
CONCLUSIONIncreased HO-1 expression may play a role in the pathogenesis of CRSwNP, which may be considered as the therapeutic target.

Multiple signaling pathways are involved in the regulation of cell proliferation and differentiation in odontogenesis and dental tissue renewal, but the details of these mechanisms remain unknown. Here, we investigated the expression patterns of a transcription factor, Krüppel-like factor 6 (KLF6), during the development of murine tooth germ and its function in odontoblastic differentiation. KLF6 was almost ubiquitously expressed in odontoblasts at various stages, and it was co-expressed with P21 (to varying degrees) in mouse dental germ. To determine the function of Klf6, overexpression and knockdown experiments were performed in a mouse dental papilla cell line (iMDP-3). Klf6 functioned as a promoter of odontoblastic differentiation and inhibited the proliferation and cell cycle progression of iMDP-3 through p21 upregulation. Dual-luciferase reporter assay and chromatin immunoprecipitation showed that Klf6 directly activates p21 transcription. Additionally, the in vivo study showed that KLF6 and P21 were also co-expressed in odontoblasts around the reparative dentin. In conclusion, Klf6 regulates the transcriptional activity of p21, thus promoting the cell proliferation to odontoblastic differentiation transition in vitro. This study provides a theoretical basis for odontoblast differentiation and the formation of reparative dentine regeneration.

The crosstalk between the nerve and stomatognathic systems plays a more important role in organismal health than previously appreciated with the presence of emerging concept of the "brain-oral axis". A deeper understanding of the intricate interaction between the nervous system and the stomatognathic system is warranted, considering their significant developmental homology and anatomical proximity, and the more complex innervation of the jawbone compared to other skeletons. In this review, we provide an in-depth look at studies concerning neurodevelopment, craniofacial development, and congenital anomalies that occur when the two systems develop abnormally. It summarizes the cross-regulation between nerves and jawbones and the effects of various states of the jawbone on intrabony nerve distribution. Diseases closely related to both the nervous system and the stomatognathic system are divided into craniofacial diseases caused by neurological illnesses, and neurological diseases caused by an aberrant stomatognathic system. The two-way relationships between common diseases, such as periodontitis and neurodegenerative disorders, and depression and oral diseases were also discussed. This review provides valuable insights into novel strategies for neuro-skeletal tissue engineering and early prevention and treatment of orofacial and neurological diseases.
