its moderate expression (HR 2.70, 95% CI 0.98-7.38; p= 0.04) by multivariate analysis.

Our findings strongly supported that high cytoplasmic expression of DCLK1-S compared to its moderate expression could be considered an independent prognostic factor influencing DSS.

Melanoma is fatal cancer originating from melanocytes, whose high metastatic potential leads to an extremely poor prognosis.

This study aimed to reveal the relationship among EMT, TIICs, and immune checkpoints in melanoma.

Gene expression data and clinical data of melanoma were downloaded from TCGA, UCSC Xena and GEO databases. EMT-related DEGs were detected for risk score calculation. "ESTIMATE" and "xCell" were used for estimating TIICs and obtaining 64 immune cell subtypes, respectively. Moreover, we evaluated the relationship between the risk score and immune cell subtypes and immune checkpoints.

Seven EMT-related genes were selected to establish a risk scoring system because of their integrated prognostic relevance. The results of GSEA revealed that most of the gene sets focused on immune-related pathways in the low-risk score group. The risk score was significantly correlated with the xCell score of some TIICs, which significantly affected the prognosis of melanoma. Patients with a low-risk score may be associated with a better response to ICI therapy.

The individualized risk score could effectively conduct risk stratification, overall survival prediction, ICI therapy prediction, and TME judgment for patients with melanoma, which would be conducive to patients' precise treatment.

Investigating aberrant tumor-specific methylation in plasma cell-free DNA provides a promising and noninvasive biomarker for cancer detection.

We aimed to investigate methylation status of some promoter regions in the plasma and tumor tissues to find biomarkers for early detection of colorectal cancer.

This case-control study on seventy colorectal cancer patients and fifty matched healthy controls used Methylation-Specific High-Resolution Melting Curve analysis to evaluate the methylation of the selected promoter regions in converted genomic tissue DNA and plasma cfDNA.

The methylation levels in selected regions of SPG20 (+24375 to +24680, +24209 to +24399, and +23625 to +23883), SNCA (+807 to +1013, +7 to +162, and -180 to +7), FBN1 (+223 to +429, +1 to +245, and -18 to -175), ITF2 (+296 to +436 and -180 to +55), SEPT9 (-914412 to -91590 and -99083 to -92264), and MLH1 (-13 to +22) were significantly higher in tumor tissues compared with normal adjacent tissues. The methylation levels of FBN1, ITF2, an be an excellent simple, non-invasive blood-based test for early detection of CRC.Drug resistance is a critical factor responsible for the recurrence of non-small cell lung cancer (NSCLC). Previous studies suggest that curcumin acts as a chemosensitizer and radiosensitizer in human malignancies, but the underlying mechanism remains elusive. In the present study, we explored how curcumin regulates the expression of miR-142-5p and sensitizes NSCLC cells to crizotinib. We found that miR-142-5p is significantly downregulated in NSCLC tissue samples and cell lines. Curcumin could increase crizotinib cytotoxicity by epigenetically restoring the expression of miR-142-5p. Furthermore, curcumin treatment suppressed the expression of DNA methylation-related enzymes, including DNMT1, DNMT3A, and DNMT3B, in NSCLC cells. In addition, the upregulation of miR-142-5p expression increased crizotinib cytotoxicity and induced apoptosis in tumor cells in a similar manner to that of curcumin. Strikingly, miR-142-5p overexpression suppressed crizotinib-induced autophagy in A549 and H460 cells. Mechanistically, miR-142-5p inhibited autophagy in lung cancer cells by targeting Ulk1. Overexpression of Ulk1 abrogated the miR-142-5p-induced elevation of crizotinib cytotoxicity in A549 and H460 cells. Collectively, our findings demonstrate that curcumin sensitizes NSCLC cells to crizotinib by inactivating autophagy through the regulation of miR-142-5p and its target Ulk1.
Early recurrence is the main obstacle for long-term survival of hepatocellular carcinoma (HCC) patients after curative resection.

We aimed to develop a long non-coding RNA (lncRNA) based signature to predict early recurrence.

Using bioinformatics analysis and quantitative reverse transcription PCR (RT-qPCR), we screened for lncRNA candidates that were abnormally expressed in HCC. The expression levels of candidate lncRNAs were analyzed in HCC tissues from 160 patients who underwent curative resection, and a risk model for the prediction of recurrence within 1 year (early recurrence) of HCCs was constructed with linear support vector machine (SVM).

A lncRNA-based classifier (Clnc), which contained nine differentially expressed lncRNAs including AF339810, AK026286, BC020899, HEIH, HULC, MALAT1, PVT1, uc003fpg, and ZFAS1 was constructed. In the test set, this classifier reliably predicted early recurrence (AUC, 0.675; sensitivity, 72.0%; specificity, 63.1%) with an odds ratio of 4.390 (95% CI, 2.120-9.090). Clnc showed higher accuracy than traditional clinical features, including tumor size, portal vein tumor thrombus (PVTT) in predicting early recurrence (AUC, 0.675 vs 0.523 vs 0.541), and had much higher sensitivity than Barcelona Clinical Liver Cancer (BCLC; 72.0% vs 50.0%), albeit their AUCs were comparable (0.675 vs 0.678). Moreover, combining Clnc with BCLC significantly increased the AUC, compared with Clnc or BCLC alone in predicting early recurrence (all P< 0.05). Finally, logistic and Cox regression analysis suggested that Clnc was an independent prognostic factor and associated with the early recurrence and recurrence-free survival of HCC patients after resection, respectively (all P= 0.001).

Our lncRNA-based classifier Clnc can predict early recurrence of patients undergoing surgical resection of HCC.

Long non-coding RNAs (lncRNAs) were detected extraordinarily expressed in various tumors and could combine with microRNAs (miRNAs) to play important role in tumor cells. This study is to explore the role of lncRNA RP11-909N17.2 in NSCLC and discuss in what way it functions in NSCLC.

120 NSCLC patients were enlisted in this study. Expression levels of lncRNA RP11-909N17.2 and miR-767-3p were detected and the correlation between lncRNA RP11-909N17.2 expression and the clinical data characteristics was analyzed. Prognosis potential of lncRNA RP11-909N17.2 was inferred with Kaplan-Meier and multivariate Cox regression assays. Biological functions of NSCLC cells were accessed by cell counting Kit-8, transwell migration and invasion assay. Mechanism of RP11-909N17.2 action on NSCLC cells was investigated by luciferase activity assay with wide-type or mutation.

LncRNA RP11-909N17.2 has an ascendant expression while miR-767-3p has descended one in NSCLC tissue specimens and cells. Over-expression of lncRNA RP11-909N17.2 can shorten the overall survival period of NSCLC patients when compared with low expression. Knockdown of lncRNA RP11-909N17.2 suppressed biology function of NSCLC cell including proliferation, migration, and invasion.

LncRNA RP11-909N17.2 can be developed into a prognostic index for NSCLC. LncRNA RP11-909N17.2 plays a promoting role in NSCLC cells possibly by binding miR-767-3p as a sponge.

Therapeutic exercise (TE) is recommended in multimodal treatment for patients with non-specific chronic back pain (cLBP).

The aim of this study is to identify an exercise or a spectrum of exercises, well described and reproducible by the clinician, for cLBP patients.

Systematic review by researching in the databases MEDLINE, EMBASE, PEDro, CINAHL, and Scopus. Evidence from Randomized Controlled Trials (RCTs) supported the TE in patients with non-specific cLBP, provided that it was well described and could be repeated by another therapist. Methodological evaluation was performed using the PEDro scale and only studies with a score of ⩾ 6 were included. The assessment of the intervention description was carried out with the TIDieR checklist. U0126 The risk of bias was examined.

Twenty-one articles were included in this systematic review. The defective description and the poorly reporting of the intervention makes it more difficult for the clinician to include the TE into clinical practice.

The findings of this study showed that the reporting of the intervention in high quality RCT on chronic low back pain is low, threatening the external validity of the results.

Ultrasound is increasingly being utilized in the diagnosis and treatment of adhesive capsulitis.

To compare the therapeutic effects and advantages of combined handheld ultrasound and fluoroscopy-guided intra-articular corticosteroid injection with those of conventional ultrasound-guided corticosteroid injection in adhesive capsulitis of the shoulder.

A total of 39 patients diagnosed with adhesive capsulitis of the shoulder were randomly assigned into two groups. Group A patients (n= 19) underwent combined handheld ultrasound and fluoroscopy-guided corticosteroid injection and group B patients (n= 20) underwent conventional ultrasound-guided corticosteroid injection to the intra-articular space of the shoulder twice. Treatment efficacy was assessed at 2 and 6weeks after the final injection, based on the verbal numeric pain scale, Shoulder Pain and Disability Index, and range of motion. Secondary outcome measures were the accuracy and procedure time.

Both injection methods were effective in the treatment of adhesive capsulitis. No significant differences in treatment efficacy and injection accuracy were observed between the two groups (p> 0.05).

This study showed no statistical differences in treatment efficacy between 2 groups. However, the combined use of ultrasound and fluoroscopy can increase the accuracy of injection compared with conventional ultrasound alone.

A framework to establish the biopsychosocial patient profile for persons with low back pain has been recently proposed and validated The Pain and Disability Drivers Management model (PDDM). In order to facilitate its clinical integration, we developed the PDDM rating scale.

To determine the inter-rater agreement of the PDDM rating scale. A second objective was to determine if this inter-rater agreement varies according to the complexity of patients' clinical presentation.

We recruited physiotherapists during workshops on the PDDM. We asked each participant to assess two clinical vignettes using the rating scale. One vignette presented a typical clinical presentation (moderate level of difficulty) and one presented an atypical presentation (complex level of difficulty). We determined inter-rater agreement with the proportion of participants who gave the same answer for each PDDM domain.

For the typical vignette, the inter-rater agreement per domain was moderate to good (between 0.54 and 0.97). For the complex vignette, the inter-rater agreement per domain was poor to good (between 0.
