Abstract
Abstract
Background
Plaque erosion with subsequent coronary thrombosis is considered as an important cause of ST-segment elevation myocardial infarction (STEMI). Smoking is a major risk factor for acute coronary thrombosis. However, the relationship between current smoking status and plaque erosion has not been systematically investigated.
Purpose
The present study aimed to investigate predictors of plaque erosion in current smokers and non-current smokers with STEMI by using optical coherence tomography (OCT).
Methods
Between January 2015 to December 2017, a total of 1313 STEMI patients underwent pre-intervention OCT of culprit lesion were enrolled and divided into two groups based on current smoking status: current smoking group (n=713) and non-current smoking group (n=600). Using established criteria, quantitative and qualitative underlying plaque characteristics were assessed by OCT. Clinical, angiographic and OCT characteristics of all enrolled patients were recorded. Univariable and multivariable logistic regression analyses were used to identify predictors of plaque erosion in two groups.
Results
Plaque erosion were found in 30.9% (220/713) culprit lesions in current smoking group and 20.8% (125/600) of those in non-current smoking group detected by OCT. In multivariate regression analysis, the predictors that strongly related to plaque erosion in the current smoking group were nearby bifurcation (OR: 4.84; 95% CI:2.38–9.87; p<0.001); the minimum fiber cap thickness (FCT, OR:1.05; 95% CI:1.03–1.08; p<0.001); thin-cap fibroatheroma (TCFA, OR: 0.22; 95% CI: 0.07–0.67; p=0.007) and lipid core length (OR: 0.91; 95% CI: 0.84–0.97; p=0.007). The predictors in the non-current smoking group were nearby bifurcation (OR: 4.84; 95% CI: 2.38–9.87; p=0.006); the minimal FCT (OR: 1.09; 95% CI: 1.06–1.13; p<0.001); multi-vessel disease (MVD, OR: 0.43; 95% CI: 0.19–0.97; p=0.042) and dyslipidemia (OR: 0.34; 95% CI: 0.14–0.84; p=0.020).
Conclusions
Predictors of plaque erosion causing STEMI onset are different between current smokers and non-current smoker, with nearby bifurcation and thicker minimal FCT both predicting plaque erosion in two groups of patients.

Abstract
Abstract
Background
Plaque erosion is a frequent and important mechanism of acute coronary thrombosis only secondary to plaque rupture. Recent studies suggested plaque erosion with noncritical stenosis could be treated conservatively that distinct from those with critical stenosis. However, characteristics of plaque erosions with different coronary stenosis remain unknown.
Purpose
The present study aimed to investigate morphological features of plaque erosions with different coronary stenosis using optical coherence tomography (OCT).
Methods
Consecutive ST-segment elevated myocardial infarction (STEMI) patients with OCT images of culprit lesion between August 2014 and December 2017 were enrolled and 348 cases presented with plaque erosion identified by OCT. Based on the severity of lumen area stenosis [calculated by (1-minimal lumen area/reference lumen area) * 100%], all culprit plaque erosions were divided into three groups: Group A (area stenosis<50%, n=50, 14.4%); Group B (50%≤area stenosis<75%, n=146, 42.0%); Group C (area stenosis≥75%, n=152, 43.7%). Clinical characteristics, lesion features detected by coronary angiography and OCT were compared among three groups.
Results
Of all 348 STEMI patients with plaque erosions, patients in Group A were youngest (p=0.008) and had the lowest frequency of hypertension (p=0.029) as compared with those in Group B and C. Angiographic analysis showed 72.0% of plaque erosions in Group A located in LAD, while 67.8% in Group B and 53.9% in Group C (p=0.039). OCT findings (Figure 1-A) showed the prevalence of fibrous plaque was significantly highest in Group A than those in Group B and C (82.0% vs. 54.8% vs. 34.9%, p<0.001), whereas lipid rich plaque was most frequent in Group C (16.0% vs. 43.8% vs. 62.5%, p<0.001). The prevalence of macrophage (p<0.001), microvessel (p=0.009) and cholesterol crystals (p<0.001) increased gradually from plaque erosion with lumen area stenosis <50% to 50–75% to ≥75%. Notably, compared with Group B and C, nearby bifurcation was most common in Group A (72.0% vs. 67.1% vs. 55.3%, p=0.036). Multivariable regression analyses (Figure 1-B) showed fibrous plaque and nearby bifurcation were independently associated with plaque erosion with noncritical stenosis (area stenosis<75%).
Conclusion
56.3% plaque erosion in STEMI patients presented with noncritical stenosis, having distinct morphological features from erosion with critical stenosis. Fibrous plaque and nearby bifurcation were independently associated with the presence of noncritically stenotic plaque erosion, remaining a desire to tailor treatment therapy to individual patients.

Abstract
Abstract
Background
Chronic inflammatory infiltration is a common process for atherosclerosis development. However, autopsy studies reveal that incidence rate of inflammatory infiltrates are less abundant in plaque erosion compared with plaque rupture.
Purpose
Studies performed by optical coherence tomography (OCT) have allowed to establish the severity of plaque inflammation by assessing macrophage infiltration (MØI). In this study, we aimed at assessing the impaction of MØI in plaque erosion among patients with STEMI by using OCT.
Methods
A total of 1561 patients with ST-segment elevation myocardial infarctions (STEMI) who underwent OCT imaging were enrolled in this study. According to the exclusion criteria, 312 patients with STEMI exhibiting plaque erosion were classified as MØI or no MØI.
Results
163 (52.2%) patients had MØI at the site of plaque erosion, whereas 149 (47.8%) patients had no evidence of MØI and patients of MØI group were significantly older (P=0.015). The result of angiography showed the prevalence of multi-vessel disease appeared more frequency (P=0.021) and diameter stenosis% were higher (P=0.031) in MØI group. OCT results showed the minimum fibrous-cap thickness was thinner (P<0.001) and the maximum lipid arc was larger (P=0.005) in MØI group. Some patients underwent imaging follow-up at 1 year. There was no significant difference in the culprit plaque morphology progress among two groups (Figure 1A-1D).
Conclusions
This study demonstrated that plaque inflammation can increase culprit lesion severity and plaque vulnerability in patients with STEMI caused by plaque erosion.

Abstract
As one of the most densely innervated tissues, the dental pulp contains abundant nerve fibres, including sensory, sympathetic and parasympathetic nerve fibres. Studies in animal models and human patients with pulpitis have revealed distinct alterations in protein expression and histological appearance in all types of dental nerve fibres. Various molecules secreted by neurons, such as classical neurotransmitters, neuropeptides and amino acids, not only contribute to the induction, sensitization and maintenance of tooth pain, but also regulate non-neuronal cells, including fibroblasts, odontoblasts, immune cells and vascular endothelial cells. Dental nerves are particularly important for the microcirculatory and immune responses in pulpitis via their release of a variety of functional substances. Further, nerve fibres are found to be involved in dental soft and hard tissue repair. Thus, understanding how dental nerves participate in pulpitis could have important clinical ramifications for endodontic treatment. In this review, the roles of dental nerves in regulating pulpal inflammatory processes are highlighted and their implications for future research on this topic are discussed.

Abstract
AIM The aim was to determine the diagnostic value of epithelial-mesenchymal transition typing of circulating tumour cells (CTCs) in colorectal cancer (CRC). METHOD Peripheral blood samples were collected from 51 CRC patients before anti-tumour treatment from April 2016 to June 2018 at the Peking University Shenzhen Hospital. The blood samples were analysed using the CanPatrol CTC typing technique (SurExam, Guangzhou, China), which combines nanomembrane enrichment with mRNA in situ hybridization. Based on the marker expression, the CTCs were classified into epithelial, epithelial mesenchymal and mesenchymal (M-CTC) types. The correlation between the CTC counts and clinicopathological characteristics such as gender, age, TNM stage, lymph node metastasis and distant metastasis were analysed by univariate and multivariate Cox regression models. The overall survival and progression-free survival (PFS) of patients demarcated by CTC typing were analysed using the Kaplan-Meier method and log-rank tests. RESULT M-CTCs were detected more frequently in patients with lymph node metastasis (N2 81.8%; N1 72.7%; N0 38.9%) as well as distant metastasis (M0 50%; M1a 81.25%; M1b 85.7%) compared to those without metastasis. In addition, the presence of M-CTCs was significantly correlated with distant metastasis (P < 0.01). Univariate analysis showed that lymph node metastasis (P = 0.035), distant metastasis (P < 0.001) and total CTC count ≥ 4 (P = 0.007) and M-CTC count ≥ 1 (P < 0.001) were significantly associated with unfavourable PFS, and lymph node metastasis (P = 0.04), distant metastasis (P = 0.01) and M-CTC count ≥ 1 (P < 0.001) were significantly associated with unfavourable overall survival. Multivariate analysis showed that the presence of M-CTCs was the only independent prognostic factor for poor PFS, and patients with M-CTCs had significantly shorter PFS than those without (P = 0.011). CONCLUSION M-CTCs are significantly associated with CRC severity and metastasis, and M-CTC count is an independent predictor of prognosis.

Abstract
Osteoradionecrosis of the mandible (MORN) is one of the most devastating complications caused by radiation therapy in the head and neck region. It is characterized by infection and chronic necrosis of the mandible as the main manifestation. Clinically, MORN-related symptoms include swelling, pain, dysphagia, trismus, masticatory or speech disorders, refractory orocutaneous fistula, bone exposure, and even pathological fracture. MORN has become a challenging clinical problem for oral and maxillofacial surgeons to deal with, but thus far, this problem has not been solved due to the lack of widely accepted treatment algorithms or guidelines. Because of the nonexistence of standardized treatment criteria, most clinical treatment against MORN nowadays is largely based on controversial empirical understandings, while recommendations on post-therapeutic evaluations are scarce. Therefore, to further unify and standardize the diagnosis and treatment of MORN, to decrease the huge waste of medical resources, and ultimately, to improve the wellbeing of the patients, the Chinese Society of Oral and Maxillofacial Surgery (CSOMS) convened an expert panel specialized in MORN from 16 domestic medical colleges and affiliated hospitals to discuss the spectrum of diagnosis and and formulate treatment. In addition, consensus recommendations were also revised with a comprehensive literature review of the previous treatment experiences and research pearls. This 'expert consensus statement on diagnosis and clinical management of MORN' is for clinical reference.

Abstract
Objective: To report the clinical features of anti-MDA5 antibody positive juvenile dermatomyositis (JDM) complicated with severe interstitial lung disease (ILD). Methods: The clinical data of three patients, who was admitted to the Department of Rheumatology and Immunology, Children's Hospital of the Capital Institute of Pediatrics from September 2016 to July 2017, with anti-melanoma differentiation associated gene 5 (MDA5) antibody positive JDM complicated with ILD were retrospectively extracted and analyzed. Meanwhile, PubMed database, CNKI, Wanfang database and China Biology Medicine disc (from their establishment to February 2019) with the key words "juvenile dermatomyositis" "interstitial lung disease" , and "anti-MAD5 antibody" both in English and Chinese were searched. Results: There were 2 females and 1 male (P1-P3), aged from 10 years 3 months to13 years 4 months, the time from onset to diagnosis were 2 months, 4 months and 10 months. All presented with rash. One of them had decreased muscle strength, and two had decreased activity tolerance. Creatine kinase was 588, 915 and 74 U/L, and serum ferritin were 1 792, >2 000 and 195.4 μg/L. All three patients had positive anti-MDA5 antibodies. At the time of diagnosis, all of them had ILD, pneumothorax and mediastinal emphysema, but had no respiratory symptoms. All three patients received oral methylprednisolone and cyclophosphamide pulse therapy, while human immunoglobulin was given only to P1 and P2. P1 developed rapid progressive pulmonary interstitial disease (RPILD) and died of respiratory failure after 2 months. While P2 and P3 were followed up for 1 to 2 years, who had complete remission, as anti-MDA5 antibody turned to negative and ILD improved significantly. Ten related reports in literature were retrieved, without reported Chinese cases, and most cases initiated with rash and very likely complicated with arthritis. Some of them were more likely to have ILD rather than muscle weakness. It also showed that Japanese JDM children had higher rate of positive anti-MDA5 antibody than patients from the U.S. and U.K., and are more susceptible to ILD and RPILD. The mortality rate of patients with RPILD is extremely high. Conclusions: The cases of JDM with positive anti-MDA5 antibody mainly presented with rash and mild muscle weakness, and could be complicated with ILD, pneumothorax and mediastinal emphysema without respiratory symptoms at early stage. Anti-MDA5 antibody titer is related to disease activity and can turn to negative after treatment.

Abstract
Objective:To explore the application value of ultrasound in etiologic judgement of hoarseness after thyroidecomy. Method:Sixty-three cases of hoarseness after thyroidecomy were examed by laryngeal ultrasonography. Vocal cord, arytenoid cartilage, pyriform fossa, thyroid operation area and recurrent laryngeal nerve pathway were evaluated. Regard electronic laryngoscope results as gold standard and compare the differences between the two methods. Result:Sixty-three patients were detected by ultrasound, then, 29 cases were diagnosed with left vocal cord paralysis, 24 cases with right vocal cord paralysis, 2 cases with bilateral vocal cord paralysis, 1 case with right vocal cord polyp, 3 cases with left vocal cord polyp, 1 case with renke layer edema, and 3 cases has normal laryngeal imaging. The accuracy of ultrasonography in determining the etiology of hoarseness after thyroidecomy is 92.1%, the sensitivity is 93.3%, and the specificity is 66.7%. Conclusion:The ultrasonography can not only show laryngeal structures, but also display thyroid operation area and recurrent laryngeal nerve pathway. Moreover, as an non-invasive method, ultrasonography has high accuracy in etiologic judgement of hoarseness after thyroidecomy and certain clinical application values.

Abstract
The presence of pesticide residues in fresh fruits and vegetables poses a serious threat to human health. Brassinosteroids (BRs) can reduce pesticide residues in plants, but the underlying mechanisms still remain unclear. Here, we identified a tomato glutaredoxin gene GRXS25 which was induced by 24-epibrassinolide (EBR) and chlorothalonil (CHT) in a way dependent on apoplastic reactive oxygen species (ROS). Silencing of GRXS25 in tomato abolished EBR-induced glutathione S-transferases (GSTs) gene expression and activity, leading to an increased CHT residue. Yeast two-hybrid and bimolecular fluorescence complementation assays showed protein-protein interaction between GRXS25 and a transcription factor TGA2. Electrophoretic mobility shift and chromatin immunoprecipitation assays indicated that TGA2 factor bound to the TGACG-motif in the GST3 promoter. While silencing of TGA2 strongly compromised, overexpression of TGA2 enhanced expression of GST genes and CHT residue metabolism. Our results suggest that BR-induced apoplastic ROS trigger metabolism of pesticide residue in tomato plants through activating TGA2 factor via GRXS25-dependent posttranslational redox modification. Activation of plant detoxification through physiological approaches has potential implication in improving the food safety of agricultural products.

Abstract
OBJECTIVE Atrial fibrillation (AF) is the most common type of arrhythmia, especially in rheumatic heart disease (RHD) patients. The differences in structural remodeling and electrical remodeling between the left and right atrium associated with AF in RHD patients are well known, and alterations in the expression profiles of long noncoding RNAs (lncRNAs) in the left atrium have also been investigated. However, the role of lncRNAs in the right atrium (RA) remains largely unknown. PATIENTS AND METHODS We identified differentially expressed lncRNAs in RA tissues of RHD patients with AF or a normal sinus rhythm (NSR) using microarray analysis. Then, we performed gene ontology (GO) and KEGG pathway analyses for functional annotation of the deregulated lncRNAs. Finally, we constructed a lncRNA-mRNA co-expression network. RESULTS Of the 22,829 human non-coding RNAs analyzed, a total of 1,909 long non-coding RNAs were detected. A total of 182 lncRNAs (117 downregulated and 65 upregulated) were shown to be differentially expressed (fold-change > 1.5) in AF patients compared with NSR patients. Many lncRNAs might be partially involved in an AF-related pathway. CONCLUSIONS AF dysregulates the expression of lncRNAs in the RA of RHD patients. These findings may be useful for exploring potential therapeutic treatments for AF in RHD patients.

Abstract
Stature is an important quantitative trait for cattle performance, which influences herd productivity. Previous studies have reported that an SNP (AC_000171.1:g.25015640G>T, rs109815800) in Pleomorphic adenoma gene 1 (PLAG1) on chromosome 14 (CHR14) is associated with bovine stature. To validate whether rs109815800 is associated with the body height of Chinese cattle, we carried out an association analysis using 558 adult cattle samples from seven populations. Then, 1038 samples from 38 Chinese cattle breeds were used to show the geographical distribution of this variant in China. The results showed that the Q allele (G allele) increased the height of cattle. Furthermore, the frequencies of Q allele in Chinese native breeds tend to decrease from northern China to southern China, and the frequency of Q allele in two Chinese beef cattle breeds is much higher than that in another 36 Chinese local cattle breeds. Our data suggest that the prevalence of the Q allele is correlated with latitude in China.

Abstract
Abstract
Background
Early risk stratification was strongly recommended to guide therapeutic management and to improve outcome for ST elevation myocardial infarction (STEMI) patients. Anaemia and high haemoglobin levels are common in STEMI patients, but the effect of the haemoglobin level on the prognosis of STEMI patients remains in dispute. The China Acute Myocardial Infarction registry-ST Elevation Myocardial Infarction (CAMI-STEMI) score can predict in-hospital mortality among Chinese STEMI patients, with similar performance to the well-established Thrombolysis in Myocardial Infarction (TIMI) score, while relying solely on simple and practical variables. This study aimed to evaluate the prognostic value of the haemoglobin level combined with the CAMI-STEMI score in STEMI patients after percutaneous coronary intervention (PCI).
Methods
We included 360 STEMI patients who underwent PCI. The patients were divided into 3 groups according to the first haemoglobin value after PCI, group 1 (male: Hb<120 g/L, female: Hb<110 g/L; 42 cases), group 2 (male: 120 g/L ≤ Hb<160 g/L, female: 110 g/L≤Hb<150 g/L; 278 cases), and group 3 (male: Hb ≥160 g/L, female: Hb ≥150 g/L; 40 cases). Clinical characteristics, and the incidence of major adverse cardiovascular and cerebral events (MACCE) during the follow-up period were recorded.
Results
The incidence of MACCE in the 3 groups increased with a decrease in the haemoglobin level. Multivariate regression analysis showed that the CAMI-STEMI score was an independent predictor of MACCE incidence at 30 days after PCI and that anaemia was an independent predictor of MACCE incidence at 6 months and 1 year after PCI. A high haemoglobin level was an independent predictor of MACCE incidence at 1 year after PCI. The area under receiver operating characteristic curves (AUCs) of the haemoglobin level, CAMI-STEMI score and haemoglobin level combined with CAMI-STEMI score predicting the occurrence of MACCE in STEMI patients within 30 days after PCI were 0.604, 0.614, and 0.639, respectively.
Figure 1. MACCE-free survival curve
Conclusion
The CAMI-STEMI score was an independent predictor of MACCE incidence at 30 days after PCI. The haemoglobin level combined with the CAMI-STEMI score improved the predictive value of MACCE in STEMI patients within 30 days after PCI.

Abstract
Abstract
Background
Acute ST-segment elevation myocardial infarction (STEMI) is typically characterized by an occlusive coronary thrombus propagation on a disrupted or eroded atherosclerotic plaque. A variable period of plaque instability and thrombus formation occur days or weeks old in approximately 50% of patients with STEMI. Presence of late stage (older) thrombi in aspirated coronary material is an independent predictor of 1-year and long-term mortality in STEMI patients. However, the relationship between coronary thrombus healing to underlying plaque morphology and characteristics in vivo still remains largely unknown.
Purpose
Our objective was to assess differences in thrombus healing between ruptured and eroded plaques in vivo and evaluate the impact of underlying plaque characteristics on thrombus healing using optical coherence tomography (OCT).
Methods
Analyzable coronary material was obtained during primary percutaneous coronary intervention (PCI) from 135 patients with STEMI within 12h of symptom onset. Thrombi were morphologically classified as either early or late stage (lytic changes or organization). Of the 135 patients, 110 were eligible for culprit lesion evaluation using OCT. Quantitative and qualitative underlying plaque characteristics were assessed by OCT.
Results
Late-stage thrombi were found in 49 of 110 (44.5%) culprit plaques. Patients with eroded plaques more frequently had late-stage thrombi compared with ruptured plaques (59.0% vs. 36.6%, p<0.001). Subgroup analysis was performed between plaque rupture, identified in 71 patients (64.5%) and plaque erosion in 39 patients (35.5%). In plaque ruptures, patients with late-stage thrombi had larger lipid core length (12.4±3.3 vs. 14.5±3.8, p=0.020), larger rupture cavity length [1.5 (1.0, 2.0) vs. 1.9 (1.5, 2.8), p=0.034] and increased residual thrombus length [7.8 (6.3, 11.2) vs. 10.3 (7.8, 13.8), p=0.021] assessed by OCT compared with early thrombus group. However, in plaque erosions, late stage thrombi were associated with decreased residual thrombus burden compared with patients with early thrombus group [16.8 (12.8, 20.4) vs. 13.4 (10.7, 14.8), p=0.012]. No significant difference was found between thrombus healing with peak creatine kinase concentration or maximum NT-pro BNP in subgroup analysis.
Conclusions
Coronary thrombi in STEMI patients exhibited diverse phases of healing, depending on the etiology of the underlying culprit plaque in vivo. These observations indicate entirely distinct mechanisms of thrombus propagation, maturation and healing between plaque rupture and erosion, illustrating an opportunity for more tailored treatment in patients with different plaque type.

Abstract
OBJECTIVE To explore the role of miR-133b in ovarian cancer and to preliminarily elucidate the mechanism of miR-133b in epithelial-mesenchymal transition (EMT) of ovarian cancer. PATIENTS AND METHODS MiR-133b was detected in ovarian cancer specimens, and the relationship of miR-133b with each pathological index and clinical index of ovarian cancer was analyzed. The action targets of miR-133b in ovarian cancer were analyzed systematically and studied deeply via the target validation and cell function validation. Finally, the possible reasons of ovarian cancer metastasis were analyzed through the molecular regulation mechanism in EMT of ovarian cancer. RESULTS The miR-133b level in ovarian cancer was significantly lower than in normal ovarian tissues and benign ovarian tumors (p<0.05). The level of miR-133b in ovarian cancer was related to differentiated degree and lymphatic metastasis. Dual-luciferase assay indicated that connective tissue growth factor (CTGF) was the target gene regulated by miR-133b. Reverse transcriptase-polymerase chain reaction (RT-PCR) as well as Western blot results proved that the expression level of E-cadherin representing the epithelial cell phenotype was increased, while the expression level of vimentin representing the mesenchymal cell phenotype was decreased. Transwell assay confirmed that the migration and invasion abilities of ovarian cancer cells declined after transfection with miR-133b plasmid. After co-transfection with miR-133b and CTGF overexpression plasmids, RT-PCR and Western blotting proved that the expression level of E-cadherin representing the epithelial cell phenotype was decreased, while the expression level of vimentin representing the mesenchymal cell phenotype was increased; transwell assay confirmed that the cell migration and invasion abilities were increased after co-transfection. CONCLUSIONS The results of this study showed that miR-133b may serve as a new molecular marker of EMT of ovarian cancer, and act as a molecular marker of differentiated degree and lymphatic metastasis of ovarian cancer.

Abstract
Objective:To explore the relationships between glucocorticoid (GC) sensitivity and the prognosis of refractory sudden sensorineural hearing loss (SSNHL), and to analyze the related factors being affected the prognosis of SSNHL. Method:Ninety-one refractory SSNHL patients were enrolled in the present investigation. Peripheral blood mononuclear cells (PBMCs) from the refractory SSNHL were extracted to conduct GC proliferation dexamethasone (DEX) inhibition experiments. All patients accepted comprehensive treatment with methylprednisolone. Result:Total effective rate was 40.66% in refractory SSNHL patients. Gender, number of affected ear, age, accompanying with vertigo, tinnitus or not and the procedure of methylprednisolone treatment were irrelevant to the efficacy. Only the inhibitory rate of DEX and the time from onset to visit were related to GC treatment effect, especially for inhibitory rate of DEX. The DEX inhibition rate of the effective group was higher than that of the ineffective group. Conclusion:DEX inhibition rate can predict GC sensitivity and prognosis of SSNHL. GC sensitivity and the time from onset to treatment are two important factors affecting the prognosis of refractory SSNHL patients..

目的 比较评估初诊时血清游离轻链比值(rFLC)及差值(dFLC)对多发性骨髓瘤(MM)患者预后的价值。 方法 收集整理2012年1月至2016年3月有FLC检测记录的479例初治MM患者的相关临床资料,采用四分位间距法将rFLC、dFLC进行分组。将rFLC分别为3组:≤14.828、14.828~364.597、≥364.597。将dFLC分为3组:≤112.85 mg/L、112.85~2 891.83 mg/L、≥2 891.83 mg/L。随后分别对不同分组进行预后分析比较。使用Kaplan-Meier进行无进展生存(PFS)和总生存期(OS)比较,使用Cox回归进行单因素、多因素预后相关性分析。 结果 不同截断范围rFLC或dFLC患者的OS及PFS差异均有统计学意义。rFLC≤14.828组OS明显优于其他两组(未达到对61个月对47个月,P=0.019);PFS与rFLC 14.828~364.597组相比,差异无统计学意义(P=0.227),与rFLC≥364.597相比,差异有统计学意义(P=0.024)。dFLC≤112.85 mg/L组与其他两组相比PFS、OS差异均有统计学意义。单因素、多因素分析显示rFLC仅与患者OS显著相关,而dFLC与患者OS、PFS均显著相关。4年OS率比较,rFLC≤14.828组4年OS率达90.84%,明显高于其他两组(59.29%、62.26%);dFLC≤112.85 mg/L组4年OS率达89.97%,明显高于其他两组(41.32%、71.95%)(P<0.05)。 结论 对于初治MM患者,不同截断范围的rFLC、dFLC对患者生存预后影响不同。其中rFLC≤14.828或dFLC≤112.85 mg/L,其生存预后差异更为明显,且具有更低的死亡风险,危险比也更低。以此截断值判断患者预后较为理想。

Abstract
Background Palliative pemetrexed-based chemotherapy remains a standard of care treatment for the majority of patients with advanced non-squamous non-small-cell lung cancer (NSCLC). Currently, no predictive markers for pemetrexed treatment are available. Methods Resected tumour samples from pemetrexed-naïve NSCLC patients were collected. Gene expression profiling with respect to predicted sensitivity to pemetrexed classified predicted responders (60%) and non-responders (40%) based on differentially expressed genes encoding for pemetrexed target enzymes. Genes showing a strong correlation with these target genes were selected for measurement of corresponding protein expressions by immunohistochemical (IHC) staining. A semi-quantitative IHC scoring method was applied to construct a prediction model for response to pemetrexed. A retrospective cohort of patients with advanced NSCLC treated with first-line pemetrexed-based chemotherapy was used for external validation. Results From ninety-one patients resected tumour samples were collected. The majority of patients had early or locally advanced NSCLC (96.3%). Gene expression profiling revealed five markers, which mRNA levels strongly correlated to pemetrexed target genes mRNA levels: TPX2, CPA3, EZH2, MCM2 and TOP2A. Of 63 (69%) patients IHC staining scores of these markers were obtained, which significantly differed between predicted non-responders and responders (P < 0.05). The optimized prediction model included EZH2 (OR = 0.56, 95% CI 0.35–0.90) and TPX2 (OR = 0.55, 95% CI 0.30–1.01). The model had a sensitivity of 86.8%, specificity of 63.6% and showed a good ability to distinct between responders and non-responders (C-index 0.86). In the external study population (N = 23) the majority of patients had metastatic NSCLC (95.7%). Partial response (PR) was established in 26.1%. The sensitivity decreased drastically to 33.3%, with a specificity of 82.4% and a C-index of 0.73. Conclusions Using external validation this prediction model with IHC staining of target enzyme correlated markers showed a good discrimination, but lacked sensitivity. The role of IHC markers as response predictors for pemetrexed in clinical practice remains questionable.

Abstract
The influences of the position of the ytterbium-doped fiber and the parasitic lasing in the amplified spontaneous emission (ASE) pump source on the spectral properties of the random fiber laser are analyzed and discussed in this paper. The experimental results show that putting ytterbium-doped fiber in the random fiber laser's cavity and using an ASE pump source with parasitic lasing are beneficial for the generation of high-order Stokes. A near-infrared supercontinuum with 20 dB bandwidth of more than 500 nm can be generated directly from a random fiber laser, which proved that a random laser fiber cannot only works as a traditional random fiber laser, but also can be a novel, simple, low-cost, low-coherence and robust near-infrared supercontinuum generation method.

Abstract
Objective: To explore the clinical features and prognostic factors of elderly MM patients. Methods: A retrospectively analysis of clinical characteristics in 93 newly diagnosed MM patients with more than 70 years of old between August 2011 and August 2016. Based on age, basic activities of daily living scale, instrumental activities of daily living scale, Charlson comorbidity index at diagnosis, patients were divided into three groups: Fit (score=0, n=15) , Intermediate fitness (score=1, n=31) , Frail (score≥2, n=47) according to a geriatric assessment system proposed by Antonio Palumbo et al. The treatment response rate, progression free survival time (PFS) and overall survival (OS) of the three groups were analyzed. Results: Complete remission was 60.0% in Fit, 22.6% in Intermediate fitness and 12.8% in Frail (Fisher χ(2)=12.398, P=0.002) . The median PFS for the three groups were 31 months, 24 months and 13 months (χ(2)=17.832, P<0.001) . The median OS was not reached for Fit, 58 months for Intermediate fitness and 25 months for Frail (χ(2)=40.678, P<0.001) . In 47 Frail cases, patients who received chemotherapy containing new drugs (proteasome inhibitor or immune-modulator) had a longer PFS (17 months vs 9 months, χ(2)=6.454, P=0.011) and patients who achieved CR had prolonged PFS and OS than non-CR (PFS: 24 months vs 12 months, χ(2)=4.117, P=0.042; OS: 37 months vs 25 months, χ(2)= 6.507, P=0.011) . Conclusion: The health status of the elderly MM patients was associated with better response and longer PFS and OS. Given on those with poor health status, new drugs may have better PFS and prolonged OS.

Abstract
Objective: To evaluate efficacy of the BiRd regimen, a combination of clarithromycin, lenalidomide, and dexamethasone, in the treatment of patients with relapsed/refractory multiple myeloma (RRMM) . Methods: Patients with RRMM treated with BiRd between September 11, 2013 and August 1, 2016 at six centers were included to evaluate overall survival rate (ORR) , clinical benefit rate (CBR) , progression-free survival (PFS) , overall survival (OS) , as well as adverse events. Results: Of 30 patients with RRMM, 27 patients were evaluable, and ORR and CBR were 51.9% (14/27) and 66.7% (18/27) respectively, including 1 sCR (3.7%) , 3 CR (11.1%) , 3 VGPR (11.1%) , and 7 PR (25.6%) . In 13 patients with prior Rd, ORR and CBR were 38.5% (5/13) and 61.5% (8/13) respectively, of which 5 patients with ≥MR carried high-risk cytogenetic[ (e.g.17p- or t (4;14) ] together with at least one of other adverse-prognostic cytogenetic (e.g.13q- and/or 1q21+) . In 24 patients with prior bortezomib-based therapy, ORR and CBR were 45.8 and 62.5%, respectively. With a median follow-up time of 14.9 (range 1.0-33.8) months, the median PFS and OS were 12.0 (95%CI 11.6-12.4) and 27.6 (95%CI 15.1-40.1) months, respectively. The BiRd regimen was well tolerated. Conclusion: The BiRd regimen is an effective and safety protocol for RRMM, including those carrying high-risk cytogenetic markers.

Abstract
Objective: To investigate the correlation between the proliferation inhibition effect of glucocorticoid (GC) on peripheral blood mononuclear cell (PBMC) and the pure tone average (PTA) improvement in SSNHL patients. Methods: Sixty inpatients with SSNHL were included from July 2013 to October 2015 in Nanjing Drum Tower Hospital, Medical School of Nanjing University. Peripheral venous blood was collected before receiving treatment, then the PBMC was isolated for GC proliferation inhibition. PBMCs of each patient were cultivated into 4 groups: Group A: PBMCs+ Medium; Group B: PBMCs+ Medium+ lipopolysaccharide (LPS, 1 μmol/L); Group C: PBMCs+ Medium+ LPS+ Dexamethasone; Group D: Medium. PBMCs were maintained in a humidified 5% CO(2) atmosphere at 37°C and were observed after 24 hours. 5-diphenyltetrazolium bromide (MTT) was used to measure PBMC proliferation inhibition rate. The PBMC proliferation inhibition rates were calculated according to the absorbance at 490 nm wavelength under a microtiter plate reader. Independent sample t tests of PBMC proliferation inhibition rate were performed between different groups. χ(2) tests were performed between gender, affected ear side, accompanied by vertigo or not, audiometric curve, time period from onset to treatment, PBMC proliferation inhibition rate and the improvement of pure tone average (PTA). Linear correlation analyses were performed between PBMC proliferation inhibition rate, the time period from onset to treatment and the hearing improvement. Results: The proliferation inhibition effect of GC on PBMC varied significantly among patients. The PBMC proliferation inhibition rate in GC insensitive group was lower than that in GC sensitive group (26.72%±21.82% vs 64.44%±25.48%, t=6.113, P<0.05). The PBMC proliferation inhibition rate in refractory group was lower than that in initial group (40.93%±28.57% vs 57.04%±31.19%, t=2.035, P=0.046). There was no statistical significance between gender, affected ear side, accompanied by vertigo or not, audiometric curve and the hearing improvement (χ(2) value was 2.320, 0.031, 2.143, 0.106, respectively, all P>0.05). Both in initial group and refractory group, the linear correlation analyses showed a significant positive correlation between PBMC proliferation inhibition rate and the PTA improvement (r value was 0.615, 0.657, respectively, all P<0.05), as well as a significant negative correlation between time period from onset to treatment and the PTA improvement(r value was -0.542, 0.370, respectively, all P<0.05). Conclusions: The proliferation inhibition rate of PBMC in vitro by GC is correlated with patients' hearing improvement. The proliferation inhibition test might be used to predict the sensitivity to GC treatment and be helpful for individualized treatment of SSNHLin clinical practice.

Abstract
Objective:To systemically evaluate the clinical significance of continuous transfixion suture for nasal septum in septoplasty. Method:Forty patients with nasal septum deviation were randomly assigned to the suture group including 20 patients who underwent endoscopic septoplasty followed by continuous transfixion suture for nasal septum, or the nasal packing group including 20 patients who underwent endoscopic septoplasty followed by nasal packing. Two groups were compared for the visual analogue scale (VAS) scores for postoperative rhinalgia, headache, lacrimation, dysphagia and sleep disorder, changes in mucociliary transport time (MTT) before and after surgery, and postoperative capillary hemorrhage. Patients were followed up for 2 weeks to observe the short-term postoperative complications. Result:Mean VAS scores for rhinalgia, headache, lacrimation, dysphagia and sleep disorder were all higher in nasal packing group than those in suture group (P<0.05); compared to suture group, there was greater prolongation of MTT before and after surgery in packing group (P<0.05); there was significant difference between two groups in postoperative capillary hemorrhage volume (P<0.05); in the nasal packing group, nasal synechia, nasal dryness and hyposmia were observed in 1, 3 and 2 patients, respectively, within 2 weeks postoperatively, whereas no short-term complications were observed in the suture group. Conclusion:Use of continuous transfixion suture in place of nasal packing following septoplasty can significantly improve the postoperative symptoms, protect nasal mucociliary clearance, and reduce short-term postoperative complications.

Abstract
AIM To profile miRNA expression between inflamed and healthy human dental pulp tissues and to investigate how the upregulation of miR-223-3p in the inflamed pulp tissue regulates odontoblast differentiation and regeneration. METHODOLOGY Microarray analysis was used to identify differences in miRNA expression patterns between healthy and inflamed pulp tissue. The results were validated using quantitative real-time PCR. To determine the effect of miR-223-3p on odontoblast differentiation, miR-223-3p was overexpressed in human dental pulp stem cells (DPSCs), which were cultured in mineralizing induction medium (to induce odontoblast differentiation). To identify the target genes of miR-223-3p, an SABiosciences Human Osteogenesis PCR Array, combined with bioinformatics, was used. Furthermore, a dual-luciferase reporter assay and a small interfering RNA (siRNA) experiment were used to confirm the relationship between miR-223-3p and its target gene. Statistical analysis was performed using the Student's t-test or one-way analysis of variance (anova); P < 0.05 was considered statistically significant. RESULTS Seventy-nine miRNAs were significantly differentially expressed (fold change >2.0; P < 0.05) between the two tissues. In particular, miR-223-3p was markedly upregulated in inflamed dental pulp. Overexpression of miR-223-3p in DPSCs significantly increased the protein levels of dentine sialophosphoprotein (DSPP) and dentine matrix protein 1 (DMP-1) (P < 0.05). However, the SMAD family member 3 (SMAD3) protein level was significantly lower than in control DPSCs (P < 0.05). Bioinformatics and the dual-luciferase assay reporter assay indicated that Smad3 was a potential target of miR-223-3p. Knockdown of Smad3 in DPSCs subjected to mineralization induction resulted in detection of DSPP and DMP-1 earlier than in control DPSCs, and it increased the protein level of alkaline phosphatase (ALP), thereby promoting odontoblast differentiation. CONCLUSIONS miR-223-3p is implicated in the regulation of odontoblast differentiation, which may be involved in the process of pulpitis repair.

Abstract
Objective:To understand the expression of LINC00460 in laryngeal squamous cell carcinoma (LSCC), and to discuss the role of LINC00460 in carcinogenesis and development of laryngeal squamous cell carcinoma. Method:The expression of LINC00460 in 68 laryngeal squamous cell carcinoma tissues and paired adjacent normal tissues were examined by real-time PCR. The relationship between the expression levels of LINC00460 and the clinicopathological features including clinical stage, histological grade, pathological type, and lymph node metastasis in LSCC was analyzed according to the clinical data. Result:The expression of LINC00460 was significantly upregulated in the LSCC tissue compared with that of adjacent normal mucosal tissue (P=0.006). There were no statistical differences of the quantity of LINC00460 expression among supraglottic, glottic and subglottic LSCC (P>0.05). Moreover, LINC00460 had no significant changes in poorly differentiated LSCC when compared with that of well and moderately differentiated LSCC (P>0.05). Furthermore, the expression of LINC00460 in LSCC with lymph node metastasis had no significant changes when compared with that without of lymph node metastasis (P>0.05). Notably, LINC00460 expression in T1+T2 stages patients were significantly lower than T3+T4 stages (P<0.05). Conclusiont:Upregulation of long non-coding RNA LINC00460 might contribute to the carcinogenesis and development of LSCC, furthermore play important biological function.

Abstract
Brassinosteroids (BRs), a group of steroid phytohormones, are involved in multiple aspects of plant growth, development and stress responses. Despite recent studies on BRs-promoted pesticide metabolism in plants, the underlying mechanisms remain poorly understood. Here, we showed that 24-epibrassinolide (EBR) significantly enhanced the expression of RESPIRATORY BURST OXIDASE HOMOLOG1 (RBOH1) and H2O2 accumulation in the apoplast of chlorothalonil (CHT, a broad spectrum nonsystemic fungicide)-treated tomato plants. Silencing of RBOH1 significantly decreased the efficiency of EBR-induced CHT metabolism. Moreover, the EBR-induced upregulation in the transcripts of glutaredoxin gene GRXS16 was suppressed in RBOH1-silenced plants. Further studies indicated that silencing of GRXS16 compromised EBR-induced increases in glutathione content, activity of glutathione S-transferase (GST) and transcript of GST1, leading to an increase in CHT residue. By contrast, overexpression of tomato GRXS16 enhanced the basal levels of glutathione content and GST activity that eventually decreased CHT residues in transgenic plants. Our results reveal that BR-mediated induction of a modest oxidative burst is essential for the acceleration of glutathione-dependent pesticide metabolism via redox modulators, such as GRXS16. These findings shed new light on the mechanisms of BR-induced pesticide metabolism and thus have important implication in reducing pesticide residues in agricultural products.

Abstract
Objective: To explore the diagnosis value of late gadolinium enhancement(LGE) detected by magnetic resonance imaging(MRI) in acute myocardial infarction(AMI) patients. Methods: The clinical and MRI data of 52 AMI patients hospitalized from January 2016 to July 2017 in our hospital were retrospectively analyzed. All patients received medication and revascularization therapies after admission and cardiac magnetic resonance examination was performed within 1 week after admission. According to whether there was LGE, AMI patients were divided into LGE(+) group(33 cases) and LGE(-) group(19 cases). According to the existence of microvascular obstruction(MVO) and/or intramyocardial hemorrhage(IMH),LGE(+) patients were divided into MVO/IMH(+) group(18 cases) and MVO/IMH(-) group(15 cases). Results: (1)There were no statistical significance between the LGE(+)group and LGE(-)group in the age, gender,smoking history, hypertension, diabetes mellitus, dyslipidemia, ventricular arrhythmia, culprit vessel, left ventricular end-diastolic volume(LVEDV), and left ventricular end-systolic volume(LVESV) (all P>0.05). The left ventricular ejection fraction was significantly lower in LGE(+) group than in LGE(-) group( (38.7±17.6) % vs. (51.2±7.9)%, P=0.001). (2)The infarct size was positively correlated with LVEDV and LVESV(r=0.436,P=0.011;r=0.479,P=0.005,respectively), and negatively correlated with left ventricular ejection fraction (r=-0.641, P<0.001) in LGE(+) group. (3) The infarct size, LVEDV, and LVESV were significantly higher in MVO/IMH(+) group thanin MVO/IMH(-) group ((26.5±7.3)%vs. (16.2±8.3)%, P=0.001; (145.7±40.9)ml vs. (112.2±23.8)ml,P=0.009; (90.0±30.8)ml vs. (61.4±19.0)ml,P=0.004, respectively), and the left ventricular ejection fraction was significantly lower in MVO/IMH(+) group than in MVO/IMH(-) group ((29.8±15.0)% vs. (49.3±14.5)%, P=0.001). Conclusions: LGE detected bycardiac magnetic resonance can provide useful information on the myocardial necrosis extent of AMI patients. Presence of MVO/IMH in LGE(+) patients is linked with larger infarct size and worse cardiac dysfunction in AMI patients.
