[Mid- and long-term results of surgical treatment of brachiocephalic Takayasu arteritis].

Objective: To examine the mid - and long-term outcomes of surgical treatment of brachiocephalic Takayasu arteritis. Methods: This is a retrospective case series study. The clinical data of 39 patients,which had been diagnosed as brachiocephalic Takayasu arteritis (244 cases),who underwent surgical treatment,were analyzed between July 2012 to November 2022 at Department of Endoluminal Vascular Surgery, the First Affiliated Hospital of Zhengzhou University. There were 5 males and 34 females, aged (37.9±14.0)years (range:13 to 71 years). Despite medical treatment, the patients suffered severe ischemic symptoms continually and then underwent surgical interventions. Among them, 20 patients underwent endovascular procedures, 11 underwent open surgical procedures, and 8 underwent hybrid procedures. Patients were followed up through outpatient visits at 1, 3, 6 months after surgery and once every year later. Follow-up was conducted until November 2022. Operation status, postoperative complications and re-intervention of patients were recorded and the Kaplan-Meier survival curves were used to analyze postoperative vascular patency rates. Results: All 39 surgeries were successful, with no intraoperative death or serious complications. The follow-up period was (48.8±38.2) months(range:1 to 123 months). Thirty-three patients experienced symptom relief after surgery, and 6 patients required secondary surgical interventions. The patency rates for the endovascular treatment group at 1-, 3-, 5-, and 10-year were 95.0%, 75.2%, 60.2%, and 60.2%, respectively, while the patency rates for open surgery were all 90.9%. In the hybrid surgery group, the patency rates at 1-, 3-, 5-, and 8-year were all 87.5%. Conclusion: For patients with brachiocephalic Takayasu arteritis, choice of an appropriate blood flow revascularization intervention should be based on the patient's condition,and the mid-and long-term outcomes are satisfactory.

Rupture of a non sinus of Valsalva aneurysm during pregnancy: Case report and review of literatures.

Ruptured Sinus of Valsalva aneurysms during pregnancy is rare and presents a threat both to the mother and the fetus. We report a case of ruptured nonsinus of Valsalva aneurysms in a 26-year-old woman diagnosed at 32+4 weeks of gestation. A successful elective lower-segment cesarean section was conducted under general anesthesia. A successful surgical correction of the ruptured aneurysm under cardiopulmonary bypass (CPB) was performed with patch repair after 13 days. A multidisciplinary approach with respect to the pregnant patient's diagnosis, indications, and timing of surgery is necessary in ensuring the best possible outcomes for both the mother and the child.

Lentigo maligna melanoma mapping using reflectance confocal microscopy correlates with staged excision: A prospective study.

BACKGROUND: Lentigo maligna/lentigo maligna melanoma (LM/LMM) can present with subclinical extension that may be difficult to define preoperatively and lead to incomplete excision and potential recurrence. Preliminarily studies have used reflectance confocal microscopy (RCM) to assess LM/LMM margins. OBJECTIVE: To evaluate the correlation of LM/LMM subclinical extension defined by RCM compared with the gold standard histopathology. METHODS: Prospective study of LM/LMM patients referred for dermatologic surgery. RCM was performed at the clinically defined initial surgical margin followed by margin-controlled staged excision with paraffin-embedded tissue, and histopathology was correlated with RCM results. RESULTS: Seventy-two patients were included. Mean age was 66.8 years (standard deviation, 11.1; range, 38-89); 69.4% were men. Seventy of 72 lesions (97.2%) were located on the head and neck with mean largest clinical diameter of 1.3 cm (range, 0.3-5). Diagnostic accuracy for detection of residual melanoma in the tumor debulk (after biopsy) had a sensitivity of 96.7% and a specificity of 66.7% when compared with histopathology. RCM margin assessment revealed an overall agreement with final histopathology of 85.9% (κ = 0.71; P < .001). LIMITATIONS: No RCM imaging beyond initial planned margins was performed. CONCLUSION: RCM showed moderate to excellent overall agreement between RCM imaging of LM/LMM and histopathology of staged excision margins.

Effects of Atomoxetine Hydrochloride on Regulation of Lifespan in Drosophila Model.

Nootropics (smart drugs) are used by students to enhance cognitive performance which have been reported times in recent years. However, some of the nootropics are central nervous system stimulants which are very likely to lead to addiction or complications such as vomiting and dizziness. Are there nootropics that can improve learning behavior while having potential positive effect on health? Here, we reported that Atomoxetine (ATX) has sex-specific effect on prolonging the life span of female Drosophila melanogaster. Further study indicated that ATX enhanced female resistance to heat stress and their vertical climbing ability, but it did decrease the number of eggs laid. ATX increased food-intake and sleep time both of females and males, and significantly reduced the 24h spontaneous activity of females and males. Our results present the sex dimorphic effect of ATX on life span regulation in Drosophila, and support further research on the beneficial role of ATX and the mechanisms in other animal models.

[Establishment of a cytokine release syndrome associated with chimeric antigen receptor T cell treatment in SCID/Beige mice model].

Objective: To establish a cytokine release syndrome (CRS) mouse model related to CAR-T cell therapy and provide a research model for the clinical phenomena. Methods: CAR-T cells targeting human CD19 molecule were constructed by molecular cloning and lentiviral transfection. Flow cytometry (FACS) was used to detect the transfection efficiency of CAR-T cells. The tumor-killing efficiency of CAR-T cells was detected by ELISA and flow cytometry. The CAR-T cells were injected into the tumor-bearing SCID/Beige mice through tail vein, and divided into phosphate buffered solution (PBS) group, low-burden group (1×10(5) Raji-Luc2 cells) and high-burden group (5×10(5) Raji-Luc2 cells). The tumor treatment effect was detected by animal in vivo imaging. Serum levels of cytokines including human IFN-γ, human IL-2, mouse IL-6, and mouse GM-CSF were measured by ELISA. The health status of the mice was evaluated by pathological examination. Results: The health scores of T cell group and T cell+ OKT-3 group were (1.15±0.08) and (2.90±0.15), respectively, after the injection of human T cell and T cell + OKT-3 antibody through tail vein, and the difference was statistically significant (P<0.001). The serum levels of human IL-2, human IFN-γ, human IL-15, mouse IL-6 and mouse GM-CSF in T cell+ OKT-3 group were (1 064.00±50.14), (1 285.00±193.90), (202.4±18.76), (1 478.00±289.20) and (350.70±42.27) pg/ml, respectively, higher than (22.67±6.36), (23.67±3.71), (44.33±14.45), (147.30±36.20), (138.00±22.74) pg/ml in T cell group (P<0.05). OKT-3 combined with human T cells caused a rapid increase in serum levels of human IL-2, human IFN-γ, mouse IL-6 and mouse GM-CSF, accompanied by an increase in body temperature and weight loss. CD19-targeting CAR-T cells were successfully constructed, and the positive rate of CAR-T cells was >30% detected by flow cytometry. ELISA results showed that in the presence of CD19 antigen, IL-2 and IFN-γ secreted by CAR-T19 cells co-incubated with Raji and Nalm were (561.00±37.07), (680.30±71.27), (369±25.71) and (523.00±26.31) pg/ml, respectively, higher than (55.00±20.53) and (64.00±7.55) pg/ml in the co-incubated with K562 group (P<0.001). Activated CAR-T19 cells were reinjected through the tail vein on the seventh day after tumor formation. Imaging experiments in mice showed that on the thirteenth day after tumor formation, the fluorescence intensities of tumors in the low-burden and high-burden groups were lower than on the seventh day of tumor inoculation, and the fluorescence intensity of tumors in the high-burden group decreased from 144.00±24.69 to 5.02±2.35 (P=0.005). The fluorescence intensity of low burden group decreased from 58.47±9.36 to 3.48±1.67 (P=0.004). The serum levels of T cell activation related cytokines IL-2, IL-15 and IFN-γ increased rapidly, and the secretion of monocyte related cytokines IL-16 and GM-CSF increased, accompanied by the typical characteristics of CRS such as increased body temperature and weight loss at 72 hours after injection of CAR-T19 cells. Conclusions: CAR-T cells targeting CD19 molecule are successfully constructed, and CRS phenomenon is verified in tumor-bearing mice by CAR-T cell re-infusion, providing an animal model for the mechanism of CAR-T treatment-related CRS and CRS prevention strategies.

Percutaneous vertebral augmentation for osteoporotic vertebral compression fractures will increase the number of subsequent fractures at adjacent vertebral levels: a systematic review and meta-analysis.

OBJECTIVE: This study aimed to investigate whether percutaneous vertebral augmentation (PVA) was associated with clinical and radiological subsequent adjacent fractures in patients with osteoporotic vertebral compression fractures. MATERIALS AND METHODS: The systematic review was performed following PRISMA guidelines. Data were retrieved from PubMed, EMBASE, Cochrane Library, Google Scholar, Web of Science, and ClinicalTrial.gov, from database inception to March 2020. Eligible studies were those that assessed subsequent adjacent fractures after PVA in comparison with conservative treatment (CT). The number of patients with adjacent secondary vertebral fractures was calculated, and the pooled risk ratio (RR) with its 95% confidence intervals (95% CI) was used. Moreover, heterogeneity, sensitivity, and publication bias analyses were performed. RESULTS: Twenty-four studies were included finally. Moreover, 20/421 (4.75%) patients from the PVA group and 25/359 (6.96%) patients from the CT group had clinical subsequent adjacent fractures, and 46/440 (10.45%) patients from the PVA group and 36/444 (8.10%) patients from the CT group had radiological subsequent adjacent fractures. Both had no significant difference between the two groups (RR = 0.67, 95% CI [0.38, 1.19], p = 0.17)/(RR = 1.13, 95% CI [0.75, 1.70], p = 0.576). However, the number of fractured vertebrae was higher in the PVA group than in the CT group (RR = 1.41, 95% CI [1.03, 1.93], p = 0.03). A sensitivity analysis did not identify specific trials that seriously deflected. No obvious publication bias was identified. CONCLUSIONS: The systematic review revealed that PVA did not increase the incidence for subsequent adjacent fractures regardless of whether they were clinical or radiological fractures. However, PVA can increase the number of subsequent fractures at adjacent vertebral levels.

Angulated small nests and cords: Key diagnostic histopathologic features of infiltrative basal cell carcinoma can be identified using integrated reflectance confocal microscopy-optical coherence tomography.

BACKGROUND: Accurate basal cell carcinoma (BCC) subtyping is requisite for appropriate management, but non-representative sampling occurs in 18% to 25% of biopsies. By enabling non-invasive diagnosis and more comprehensive sampling, integrated reflectance confocal microscopy-optical coherence tomography (RCM-OCT) may improve the accuracy of BCC subtyping and subsequent management. We evaluated RCM-OCT images and histopathology slides for the presence of two key features, angulation and small nests and cords, and calculated (a) sensitivity and specificity of these features, combined and individually, for identifying an infiltrative BCC subtype and (b) agreement across modalities. METHODS: Thirty-three RCM-OCT-imaged, histopathologically-proven BCCs (17 superficial and/or nodular; 16 containing an infiltrative component) were evaluated. RESULTS: The presence of angulation or small nests and cords was sufficient to identify infiltrative BCC on RCM-OCT with 100% sensitivity and 82% specificity, similar to histopathology (100% sensitivity, 88% specificity, kappa = 0.82). When both features were present, the sensitivity for identifying infiltrative BCC was 100% using either modality and specificity was 88% on RCM-OCT vs 94% on histopathology, indicating near-perfect agreement between non-invasive and invasive diagnostic modalities (kappa = 0.94). CONCLUSIONS: RCM-OCT can non-invasively identify key histopathologic features of infiltrative BCC offering a possible alternative to traditional invasive biopsy.

The potential utility of integrated reflectance confocal microscopy-optical coherence tomography for guiding triage and therapy of basal cell carcinomas.

The increasing rate of incidence and prevalence of basal cell carcinomas (BCCs) worldwide, combined with the morbidity associated with conventional surgical treatment has led to the development and use of alternative minimally invasive non-surgical treatments. Biopsy and pathology are used to guide BCC diagnosis and assess margins and subtypes, which then guide the decision and choice of surgical or non-surgical treatment. However, alternatively, a noninvasive optical approach based on combined reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) imaging may be used. Optical imaging may be used to guide diagnosis and margin assessment at the bedside, and potentially facilitate non-surgical management, along with long-term monitoring of treatment response. Noninvasive imaging may also complement minimally invasive treatments and help further reduce morbidity. In this paper, we highlight the current state of an integrated RCM/OCT imaging approach for diagnosis and triage of BCCs, as well as for assessing margins, which therefore may be ultimately used for guiding therapy.

Diagnostic development for parallel wave-number measurement of lower hybrid waves in EAST.

An eight-channel magnetic probe diagnostic system has been designed and installed adjacent to the 4.6 GHz lower hybrid (LH) grill antenna in the low-field side of the Experimental Advanced Superconducting Tokamak (EAST) in order to study the n∥ evolution of LH waves in the first pass from the launcher to the core plasma. The magnetic probes are separated by 6.6 mm, which allows measurement of the dominant parallel refractive index n∥ up to n∥ = 5 for 4.6 GHz LH waves. The magnetic probes are designed to be sensitive to the magnetic field component perpendicular to the background magnetic field with a slit on the casing that encloses the probe. The intermediate frequency stage, which consists of two mixing stages, down-coverts the frequency of the measured wave signals at 4.6 GHz to 20 MHz. A bench test demonstrates the phase stability of the magnetic probe diagnostic system. By evaluating the phase variation of the measured signals along the background magnetic field, the dominant n∥ of the LH wave in the scrape-off layer has been deduced during the 2019 experimental campaign. In the low density plasma, the measured dominant n∥ of the LH waves is about 2.1, corresponding to the main peak 2.04 of the launched n∥ spectrum. n∥ deduced by the least-squares linear fit method remains near this value in the low density plasma with a high spatial correlation magnitude of 0.9. With an eight-channel probe system, a wave-number spectrum has also been deduced, which has a peak near to the measured dominant n∥.

Nonlocal Spin Transport as a Probe of Viscous Magnon Fluids.

Magnons in ferromagnets behave as a viscous fluid over a length scale, the momentum-relaxation length, below which momentum-conserving scattering processes dominate. We show theoretically that in this hydrodynamic regime viscous effects lead to a sign change in the magnon chemical potential, which can be detected as a sign change in the nonlocal resistance measured in spin transport experiments. This sign change is observable when the injector-detector distance becomes comparable to the momentum-relaxation length. Taking into account momentum- and spin-relaxation processes, we consider the quasiconservation laws for momentum and spin in a magnon fluid. The resulting equations are solved for nonlocal spin transport devices in which spin is injected and detected via metallic leads. Because of the finite viscosity we also find a backflow of magnons close to the injector lead. Our work shows that nonlocal magnon spin transport devices are an attractive platform to develop and study magnon-fluid dynamics.

LINC00324 exerts tumor-promoting functions in lung adenocarcinoma via targeting miR-615-5p/AKT1 axis.

OBJECTIVE: The underlying mechanism of long non-coding RNA (lncRNA) in lung adenocarcinoma (LAC) has not been fully understood yet. Hence, this study aimed to determine the biological function of LINC00324 in LAC and to provide a novel diagnostic and therapeutic target for it. PATIENTS AND METHODS: The expression level of LINC00324 in 87 paired LAC tumor tissues and matched para-tumor tissues was detected using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Cell counting kit-8 (CCK-8) assay was employed to analyze the cell proliferative ability, whereas flow cytometry was performed to detect cell apoptotic rate. Cell metastasis change was measured using wound-healing assay and transwell assay. Luciferase reporter gene assay and Western blotting analysis were utilized to investigate the underlying mechanism of LINC00324 in LAC. RESULTS: LINC00324 was highly expressed in LAC tissues compared with the para-tumor samples. Identically, the expression level of LINC00324 was significantly higher in LAC cell lines. The overexpression of LINC00324 promoted cell proliferation and inhibited cell apoptosis of LAC cells, while knockdown of LINC00324 presented the opposite effect. Up-regulation of LINC00324 accelerated cell migration and invasion, but down-regulation of LINC0324 decreased cell metastasis of LAC cells. Furthermore, miR-615-5p was found to be regulated by LINC00324 and inhibited AKT1 expression, indicating that LINC00324 promoted cell progression via affecting the miR-615-5p/AKT1 pathway. CONCLUSIONS: LINC00324 was significantly over-expressed in LAC tissues and cells. It promoted proliferation and metastasis but inhibited cell apoptosis of LAC cells via sponging miR-615-5p to promote AKT1 expression. Our results demonstrated LINC00324 as a novel diagnostic and therapeutic target for LAC.

[Prospective association between childhood abuse experiences and depressive symptoms in adolescence].

Objective: To evaluate the prospective association between childhood abuse experiences and depressive symptoms in adolescence. Methods: Students in grade 3 and 4 from three primary schools were selected, with informed consent, through convenience cluster sampling in Bengbu, Anhui province in May 2013. The students' body height, weight were assessed. Childhood abuse experiences including emotional, physical or sexual abuses, as well as depressive symptoms were reported by children themselves. Data on parental educational background and household economic status were collected through parent questionnaire. A follow up was conducted 4 years later after baseline survey. Depressive symptoms were evaluated by using Children's Depression Inventory at baseline survey, and by using Mood and Feeling Questionnaire at follow-up. Logistic regression model was used to analyze the relationship between childhood abuse experiences and depressive symptoms in adolescence. Results: A total of 1 172 students were included in baseline survey, and a follow-up was conducted for 87.1% of them (n=1 021). Among 1 126 students with complete information on childhood abuse experiences at baseline survey, the reported rates of physical, emotional and sexual abuses were 12.8% (144/1 126), 11.1% (125/1 126) and 10.9% (123/1 126), respectively. The prevalence of depressive symptoms at baseline survey and follow-up was 7.0% (82/1 172) and 12.3% (126/1 021), respectively. After adjusted for baseline depressive symptoms, age at follow-up, sex, the only-child in family, household economic status, divorce of parents and BMI, childhood emotional and physical abuse experiences were significant risk factors for depressive symptoms in mid-adolescence, with the ORs were 1.86 (95%CI: 1.03-3.36, P=0.039) and 2.37 (95%CI: 1.39-4.03, P=0.001), respectively. Conclusion: Childhood physical and emotional abuse might increase the risk of depressive symptoms in adolescence.

Evaluation of a Combined Reflectance Confocal Microscopy-Optical Coherence Tomography Device for Detection and Depth Assessment of Basal Cell Carcinoma.

Importance: The limited tissue sampling of a biopsy can lead to an incomplete assessment of basal cell carcinoma (BCC) subtypes and depth. Reflectance confocal microscopy (RCM) combined with optical coherence tomography (OCT) imaging may enable real-time, noninvasive, comprehensive three-dimensional sampling in vivo, which may improve the diagnostic accuracy and margin assessment of BCCs. Objective: To determine the accuracy of a combined RCM-OCT device for BCC detection and deep margin assessment. Design, Setting, and Participants: This pilot study was carried out on 85 lesions from 55 patients referred for physician consultation or Mohs surgery at Memorial Sloan Kettering Skin Cancer Center in Hauppauge, New York. These patients were prospectively and consecutively enrolled in the study between January 1, 2017, and December 31, 2017. Patients underwent imaging, with the combined RCM-OCT probe, for previously biopsied, histopathologically confirmed BCCs and lesions clinically or dermoscopically suggestive of BCC. Only patients with available histopathologic examination after imaging were included. Main Outcomes and Measures: Improvements in sensitivity, specificity, and diagnostic accuracy for BCC using the combined RCM-OCT probe as well as the correlation between OCT-estimated depth and histopathologically measured depth were investigated. Results: In total, 85 lesions from 55 patients (27 [49%] were female and 28 [51%] were male with a median [range] age of 59 [21-90] years) were imaged. Imaging was performed on 25 previously biopsied and histopathologically confirmed BCCs and 60 previously nonbiopsied but clinically or dermoscopically suspicious lesions. Normal skin and BCC features were correlated and validated with histopathologic examination. In previously biopsied lesions, residual tumors were detected in 12 of 25 (48%) lesions with 100% sensitivity (95% CI, 73.5%-100%) and 23.1% specificity (95% CI, 5.0%-53.8%) for combined RCM-OCT probe. In previously nonbiopsied and suspicious lesions, BCCs were diagnosed in 48 of 60 (80%) lesions with 100% sensitivity (95% CI, 92.6%-100%) and 75% specificity (95% CI, 42.8%-94.5%). Correlation was observed between depth estimated with OCT and depth measured with histopathologic examination: the coefficient of determination (R2) was 0.75 (R = 0.86; P < .001) for all lesions, 0.73 (R = 0.85; P < .001) for lesions less than 500 µm deep, and 0.65 (R = 0.43; P < .001) for lesions greater than 500 µm deep. Conclusions and Relevance: Combined RCM-OCT imaging may be prospectively used to comprehensively diagnose lesions suggestive of BCC and triage for treatment. Further validation of this device must be performed on a larger cohort.

[Therapeutic effects of psychological intervention combined with manual reduction on benign paroxysmal positional vertigo in the elderly].

Objective:To explore the best treatment for elderly patients with benign paroxysmal positional vertigo (BPPV). Method:Sixty-eight BPPV patients aged 60-85 years were randomly divided into two groups. The control group was treated by simple manipulation. The study group was treated by manual reduction combined with psychological intervention. The curative effect was compared. Result:The cure rates of the control group and the study group were 44.4% and 43.8% respectively, with no significant difference (P>0.05); the effective rates were 52.78% and 87.50% respectively, with significant difference (P<0.05). The recurrence rates of control group and study group were 8.3% and 3.1% after 2 weeks of treatment, respectively, with no significant difference (P>0.05). The recurrence rates at 3 months were 5.6% and 0 respectively, with no significant difference (P>0.05). The difference of SAS and SDS between the two groups after treatment was statistically significant (P<0.05). There was no significant difference in the residual symptoms between the two groups at the first follow-up (P>0.05), and at 1 week and 4 weeks (P<0.05). The residual symptoms of the patients after reoperation were relieved compared with those of the control group. The DHI scores of the study group between 60-70 years old and 71-85 years old group for the first time, after 1 week and 4 weeks were statistically significant (P<0.05), and the residual symptoms in the 60-70 years group were reduced compare to the 71-85-year-old group. Conclusion:Elderly people with BPPV are susceptible to anxiety and depression. Manipulation combined with psychological intervention can promote the curative effect well, but personalized treatment plan should be developed.

Randomized phase III study of docetaxel plus bavituximab in previously treated advanced non-squamous non-small-cell lung cancer.

Background: Bavituximab is a monoclonal antibody that targets phosphatidylserine in the presence of ß2 glycoprotein 1 (ß2GP1) to exert an antitumor immune response. This phase III trial determined the efficacy of bavituximab combined with docetaxel in patients with previously treated advanced non-small-cell lung cancer (NSCLC). Patients and methods: Key eligibility criteria included advanced non-squamous NSCLC with disease progression after treatment with platinum-based doublet chemotherapy, evidence of disease control after at least two cycles of first-line therapy, presence of measurable disease, ECOG performance status 0 or 1, adequate bone marrow and organ function, and no recent history of clinically significant bleeding. Eligible patients were randomized 1 : 1 to receive up to six 21-day cycles of docetaxel plus either weekly bavituximab 3 mg/kg or placebo until progression or toxicity. The primary end point was overall survival (OS). Results: A total of 597 patients were enrolled. Median OS was 10.5 months in the docetaxel + bavituximab arm and was 10.9 months in the docetaxel + placebo arm (HR 1.06; 95% CI 0.88-1.29; P = 0.533). There was no difference in progression-free survival (HR 1.00; 95% CI 0.82-1.22; P = 0.990). Toxicities were manageable and similar between arms. In subset analysis, among patients with high baseline serum ß2GP1 levels ≥200 µg/ml, a nonsignificant OS trend favored the bavituximab arm (HR 0.82; 95% CI 0.63-1.06; P = 0.134). Among patients who received post-study immune checkpoint inhibitor therapy, OS favored the bavituximab arm (HR 0.46; 95% CI 0.26-0.81; P = 0.006). Conclusions: The combination of bavituximab plus docetaxel is not superior to docetaxel in patients with previously treated advanced NSCLC. The addition of bavituximab to docetaxel does not meaningfully increase toxicity. The potential benefit of bavituximab observed in patients with high ß2GP1 levels and in patients subsequently treated with immune checkpoint inhibitors requires further investigation. Clinical trial number: NCT01999673.

Clinical prognostic value of A FOXM1 related long non-coding RNA expression in gastric cancer.

OBJECTIVE: The aim of this study was to explore FOXM1-related LncRNA 1(FRLnc1) expression level in gastric cancer (GC) and demonstrate its association with the prognosis. PATIENTS AND METHODS: A total of 173 GC patients from Affiliated Hospital of Jining Medical University were enrolled in the study. GC tissue samples were quantified for FRLnc1 expression level using quantitative PCR (qPCR) method. The relevance between FRLnc1 expression and clinicopathological features was determined by x2-test. The association between FRLnc1 expression and overall survival was estimated by the Kaplan-Meier method. Multivariate and univariate analysis were performed to explore whether FRLnc1 was an independent prognostic factor for GC patients. RESULTS: We found that FRLnc1 expression was higher in GC tissues than corresponding adjacent tissues (p < 0.01). Increased FRLnc1 expression was associated with depth of tumor (p = 0.004), differentiation degree (p = 0.032), distant metastasis (p = 0.007), TNM stage (p = 0.006) and lymph node metastasis (p = 0.012). More importantly, Kaplan-Meier survival analysis demonstrated that overall patient survival for those with low FRLnc1 expression was significantly longer than those patients with high FRLnc1 expression (p < 0.001). Multivariate analysis suggested that FRLnc1 expression was an independent prognostic marker for survival in patients with GC. CONCLUSIONS: The data presented in this work firstly suggested that FRLnc1 may be a prognostic predictor in GC.
