ABSTRACT

Objective:To investigate the clinical value of peripheral monocyte and neutrophil count in predicting the response of patients with metastatic non-small cell lung cancer (mNSCLC) to immunosuppressive checkpoint inhibitors (ICI).Methods:The clinical data of 34 adult mNSCLC patients who received nafulizumab or pabolizumab in Danzhou People's Hospital of Hainan Province from January 2017 to March 2019 were retrospectively analyzed. The correlation of the demographic characteristics, clinical data, hematological examination results in the first two weeks before the treatment and two weeks after ICI treatment with prognosis was recorded and observed.Results:The baseline mean monocyte count [(0.52±0.09)×10 9/L vs. (0.60±0.12)×10 9/L] and neutrophil count [(4.27±0.87)×10 9/L vs.(5.39±1.02)×10 9/L] of patients with ICI reaction were lower than those of patients without ICI reaction, and the differences were statistically different ( t = -2.572, -2.727, all P < 0.05). However, there was a negative correlation between the monocyte count of the patients who responded to ICI and the reaction time ( r = -0.507, P < 0.05). The median reaction time in patients with monocyte count >0.70×10 9/L was shorter than that in patients with monocyte count ≤0.70×10 9/L (8 weeks vs. 12 weeks, χ2=4.162, P = 0.041). There was no correlation between monocyte count and time of reaction duration, progression of free survival (PFS) and overall survival (OS) ( r = -0.214, 0.182, 0.232, all P > 0.05). The decrease rate of neutrophil count in response group was higher than that in non-response group (22% vs. 2%, P < 0.05). After the first administration, cutoff value of neutrophil count was 4.2×10 9/L; the response rate of patients with neutrophil count ≤ 4.2×10 9/L was higher than that of patients with neutrophil count > 4.2×10 9/L [86.7% (13/15) vs. 36.8% (7/19), χ2=6.657, P < 0.05]. Conclusion:Peripheral blood monocyte and neutrophil count can predict the response to ICI therapy in patients with mNSCLC.

ABSTRACT

Lung cancer is currently one of the most common malignant tumors in the world. The occurrence and development of lung cancer, especially non-small cell lung cancer (NSCLC), are closely related to the abnormal expression of long non-coding RNA (lncRNA). lncRNA with a transcript of more than 200 nucleotides is involved in chromatin modification, transcription activation, transcription interference and other regulatory processes, and has varying degrees of regulation on the proliferation, migration, and invasion of tumor cells. It is characterized by up-regulation or down-regulation of expression. At present, there are a large number of studies on lncRNA, because lncRNA has considerable application prospects in the diagnosis, clinical treatment, drug resistance research and prognosis evaluation of NSCLC. In this paper, the overview of lncRNA, the up-regulation or down-regulation of NSCLC-related lncRNA expression, NSCLC clinical treatment and drug-resistant lncRNA were summarized.

ABSTRACT

BACKGROUND:Previous studies have performed three-dimensional finite element analysis on lumbar fracture fixation. However, a few studies concerned three-dimensional finite element analysis of lumbar spinal pedicle screw fixation. OBJECTIVE:To analyze the biomechanical characteristics of one-way screw and universal screw fixation for lumbar fractures using finite element method. METHODS:Models of lumbar fractures treated with one-way screw and universal screw fixation were established. Three-dimensional finite element method was used to analyze and compare the maximum axial displacement, maximum bending degree, maximum stress on thepedicle screw fixation system and maximum stress of intervertebral disc in normal vertebral fracture model, one-way and universal pedicle screw fixation models. RESULTS AND CONCLUSION:(1) The maximum axial displacement at anteflexion, posterior extension, left lateral curvature and right lateral curvature was significantly lower in the one-way fixation group and universal fixation group than in the normal group (P< 0.05-0.01). The maximum axial displacement at above directions was lower in the universalfixation group than in the one-way fixation group. (2) The maximum bending degree was significantly lower in the one-way and universal fixation groups than in the normal group (P< 0.05-0.01). The maximum bending degree at various directions was lower in the universal fixation group than in the one-way fixation group. (3) The maximum stress on the pedicle screw fixation system at various directions was lower in the universal fixation group than in the one-way fixation group (P< 0.05-0.01). (4) The maximumstress of intervertebral disc was significantly lower in the one-way and universal fixation groups than in the normal group (P< 0.05-0.01). The maximum stress of intervertebral disc at various directions was lower in the universal fixation group than in the one-way fixation group. (5) Results suggested that one-way and universal screw fixation for lumbar fracture can bear most of the stress, obviously decrease the maximum axial displacement, maximum bending degree, maximum stress on the pedicle screw fixation system and maximum stress of intervertebral disc. The stability of universal screw fixation was better than that of one-way screw fixation.

ABSTRACT

OBJECTIVE To investigate the effect of tranilast on cardiac fibroblasts proliferation and phenotype transformation incubated with a high concentration of glucose and the possible mechanism. METHODS The cardiac fibroblasts were divided into seven groups in accordance with different nutrient solutions:normal control group(5.5 mmol · L-1 glucose),hypertonic group(5.5 mmol · L-1 glucose+mannitol 25 mmol · L- 1),high glucose group (25 mmol · L- 1 glucose),tranilast intervention groups (25 mmol·L-1 glucose+tranilast 50,100 and 200μmol·L-1),and activin receptor-like kinase 7(ALK7) inhibitor group(25 mmol · L-1 glucose+10μmol · L-1 SB431542). The cell proliferation was detected by MTT method. The transformation of cardiac fibroblasts was determined by immunfluorescence staining. The expression of fibroblast specific protein 1 (FSP-1),α-smooth muscle actin (α-SMA),transforming growth factor-β1(TGF-β1)and ALK7 was assessed by Western blotting. RESULTS Compared with nor?mal control group,A492 nm of cells in high glucose group was significantly increased(P<0.01),while the expression of α-SMA,TGF-β1 and ALK7 protein in high glucose group was significantly increased(P<0.01),but FSP-1 protein was significantly decreased(P<0.01). There was no difference between normal control group and hypertonic group. Compared with high glucose group,A492 nm of cells in tranilast or SB431542 intervention groups were decreased(P<0.05),and the expression of α-SMA,TGF-β1 and ALK7 protein was significantly decreased(P<0.05),but the expression of FSP-1 protein was increased (P<0.05)in tranilast or SB431542 intervention groups. CONCLUSION Tranilast can inhibit the proliferation and phenotype transformation of cardiac fibroblasts induced by high glucose,which may be related to down-regulation of the expression of ALK7.

ABSTRACT

Objective To explore the value of strain rate imaging (SRI) technology in the diagnosis of hypertension patient with re-gional left ventricular early diastolic dysfunction. Methods 50 essential hypertension patients were divided into hypertension Group Ⅰ and Group Ⅱ, including 31 patients with normal left ventricular and 19 patients with left ventricular hypertrophy. 25 healthy people were used as the control group. SRI was done in the six different basal myocardial segments and the parameters of SRI were compared with that of Doppler tissue imaging (DTI) and pulse Doppler (PW). Results In the hypertension group, SRe of the six different basal myocardial segments was lower than that in the control group (P<0.05), but (SRa) of hypertension group was higher (P<0.05). SRe was negatively correlated with the patients'illness development (r=-0.89, P<0.05), but SRa was positively correlated (r=0.97, P<0.05). And the SRe/SRa<1 detection rate of Group Ⅱ was higher than that in Group Ⅰ, and the ratio in the control group was lowest(P<0.05). Total detection rate of SRI (88%) was higher than Em/Am <1 of DTI (79.67%) and E/A < 1 of PW(60%), and these changes were more obvious in Group Ⅰ. SRI was higher than DTT and PW (P<0.05). Conclusion Compared with traditional technology and methods, SRI could pro-vide more accurate diagnoses to hypertension patient with regional left ventricular early diastolic dysfunction.
