The effect of music therapy on language communication and social skills in children with autism spectrum disorder: a systematic review and meta-analysis.

Background: Studies have shown that music therapy can be used as a therapeutic aid for clinical disorders. To evaluate the effects of music therapy (MT) on language communication and social skills in children with autism spectrum disorder (ASD), a meta-analysis was performed on eligible studies in this field. Methods: A systematic search was conducted in eight databases: PubMed, Embase, Web of Science, Cochrane Library databases, the China National Knowledge Infrastructure (CNKI), Wanfang Data, the Chinese Biomedical Literature (CBM) Database, and the VIP Chinese Science and Technology Periodicals Database. The standard mean difference (SMD) values were used to evaluate outcomes, and the pooled proportions and SMD with their 95% confidence intervals (CIs) were also calculated. Results: Eighteen randomized controlled trial (RCT) studies were included, with a total of 1,457 children with ASD. This meta-analysis revealed that music therapy improved their language communication [SMD = -1.20; 95%CI -1.45, -0.94; χ2 (17) = 84.17, I2 = 80%, p < 0.001] and social skills [SMD = -1. 13; 95%CI -1.49, -0.78; χ2 (17) = 162.53, I2 = 90%, p < 0.001]. In addition, behavior [SMD = -1.92; 94%CI -2.56, -1.28; χ2 (13) = 235.08, I2 = 95%, p < 0.001], sensory perception [SMD = -1.62; 95%CI -2.17, -1.08; χ2 (16) = 303.80, I2 = 95%, p < 0.001], self-help [SMD = -2. 14; 95%CI -3.17, -1.10; χ2 (6) = 173.07, I2 = 97%, p < 0.001] were all improved. Conclusion: Music therapy has a positive effect on the improvement of symptoms in children with ASD. Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/.

Gender differences in the functional language networks at birth: a resting-state fNIRS study.

Numerous studies reported inconsistent results concerning gender influences on the functional organization of the brain for language in children and adults. However, data for the gender differences in the functional language networks at birth are sparse. Therefore, we investigated gender differences in resting-state functional connectivity in the language-related brain regions in newborns using functional near-infrared spectroscopy. The results revealed that female newborns demonstrated significantly stronger functional connectivities between the superior temporal gyri and middle temporal gyri, the superior temporal gyri and the Broca's area in the right hemisphere, as well as between the right superior temporal gyri and left Broca's area. Nevertheless, statistical analysis failed to reveal functional lateralization of the language-related brain areas in resting state in both groups. Together, these results suggest that the onset of language system might start earlier in females, because stronger functional connectivities in the right brain in female neonates were probably shaped by the processing of prosodic information, which mainly constitutes newborns' first experiences of speech in the womb. More exposure to segmental information after birth may lead to strengthened functional connectivities in the language system in both groups, resulting in a stronger leftward lateralization in males and a more balanced or leftward dominance in females.

The relations of psychotic-like experiences (PLEs) and depressive symptoms and the bias of depressive symptoms during the clustering among Chinese adolescents: Findings from the network perspective.

BACKGROUND: There are rare studies about the network structure of psychotic-like experiences (PLEs) and depressive symptoms among adolescents. Studies have widely acknowledged that PLEs in adolescents confer a higher risk of depressive symptoms, but the complex interactions remain inadequately understood. Our study aimed to examine the hierarchy and inter-associations of PLEs and depressive symptoms in a large adolescent sample from the network analysis perspective. METHODS: A total of 5008 Chinese adolescents were enrolled in our sample. Community Assessment of Psychic Experiences-42 (CAPE-42) was applied to build the network. Centrality indexes were calculated to represent the significance of nodes in the network. Community detection was conducted to figure out the specific clustering of nodes. Demographic information was collected for the sub-network comparisons. Accuracy and stability of the network were also tested. RESULTS: "Failure", "External control", and "Lack of activity" were the most central nodes. The main bridge nodes linking PLEs and depressive symptoms were "Failure", "Guilty", and "No future". Positive PLE "Odd looks" and negative PLE "Unable to terminate" are the two PLEs that were most relevant to depressive nodes. Community detection further demonstrated the bias of depressive nodes in the data-driven clustering. Comparative sub-network analysis suggested that age was the only demographic factor related to the current network. CONCLUSION: In this study of a large adolescent sample, we first demonstrated the network structure and specific clustering preference of PLEs and depressive symptoms. Our findings may enhance the understanding of the relationship between PLE and depressive symptoms.

Survival Analysis of 159 Patients With Advanced Non-Small-Cell Lung Cancer Resistant to First-Generation Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitor.

Background: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) have limited or no response in some certain patients of non-small-cell lung cancer (NSCLC). However, real-world survival analyses comparing clinical data and EGFR-plasma mutation are still lacking. Methods: In total, 159 patients with advanced NSCLC resistant to first-generation EGFR-TKIs were included for consecutive blood sampling in this study. Super-amplification refractory mutation system (Super-ARMS) was used to detect EGFR-plasma mutations and correlations between survival and circulating tumor DNA (ctDNA) were analyzed. Results: Among 159 eligible patients, the T790M mutation was detected in 27.0% (43/159) of patients. The median progression-free survival (mPFS) was 10.7 months in all patients. Survival analysis revealed that patients with the T790M mutation had shorter progression-free survival (PFS) than those with the T790M wild-type (10.6 months vs 10.8 months, P = .038). Patients who cleared EGFR-plasma mutation had prolonged PFS compared with those with nonclearing EGFR-plasma mutation (11.6 months vs 9.0 months, P = .001). Cox multivariate analysis showed that the nonclearance of EGFR-plasma mutations was an independent risk factor for PFS (RR = 1.745, 95% CI: [1.184, 2.571], P = .005). The T790M mutation was associated with nonclearance of the EGFR-plasma mutation (χ2 = 10.407, P = .001). Conclusion: Patients with advanced NSCLC who were resistant to the first-generation EGFR-TKI had a prolonged PFS with clearance of EGFR-plasma mutation. Those nonclearers were more likely to harbor T790M mutations in plasma.

Structural and magnetic properties of Y3(GaAlFe)5O12 liquid-phase epitaxy films with low ferromagnetic resonance losses.

Ultra-thin rare earth iron garnet (RIG) films with a narrow ferromagnetic resonance (FMR) line width and a low damping factor have attracted a great deal of attention for microwave and spintronic applications. In this work, 200 nm Y3(GaAlFe)5O12 garnet (GaAl-YIG) films were prepared on gadolinium gallium garnet (GGG) substrates by liquid-phase epitaxy (LPE) with low saturation magnetization. The microstructural properties, chemical composition, and magnetostatic and dynamic magnetization characteristics of the films are discussed in detail. According to the structural analysis, these films exhibit a low surface roughness of less than 0.5 nm. The GaAl-YIG films show an obvious temperature dependence of lattice parameter and strain state, and the film's parameter is perfectly matched with that of the GGG substrate at 810°C. There is a clear variation in the Pb level, which brings about a gradual enhancement of the coercivity and a diminution of the squareness ratio of magnetic hysteresis loops as the growth temperature is reduced. Slight changes in surface roughness, strain condition and content of Pb induce the FMR line width and damping factor to vary on a small scale. The line width is less than 10.17 Oe at 12 GHz and the damping factor is of the order of 10-4. All these properties demonstrate that these ultra-thin GaAl-YIG films are of benefit for the development of devices operated at lower frequencies and in lower fields.

Tangshen Decoction Enhances Podocytes Autophagy to Relieve Diabetic Nephropathy through Modulation of p-AMPK/p-ULK1 Signaling.

Traditional Chinese medicine has certain advantages in the prevention and treatment of diabetic nephropathy (DN); thus, Chinese medicine therapy is considered as a promising strategy for treating DN. Here, the diabetic nephropathy model was established and intervened with Tangshen Decoction to explore its repair effect on diabetic kidney injury and the mechanism of autophagy. Different doses (10, 20 g·kg-1) of Tangshen Decoction (so-called Tangshen Jian, TSJ) or metformin were used to intervene for 16 weeks. The body weight (BW) and fasting blood glucose (FBG) of rats in each group were regularly monitored; a urine protein test kit (CBB method) was used to detect changes in urine protein (UP) content. The serum biochemical indicators, including Cr (creatinine), BUN (blood urea nitrogen), TC (total cholesterol), and TG (triglyceride), were detected by an automatic biochemical analyzer. HE (hematoxylin-eosin) staining, PAS, and electron microscopy were used to observe the podocyte damage. We showed that administration of TSJ or metformin prevented the increases in FBG level, serum Cr, BUN, TC, and TG level, and urine protein excretion in diabetic nephropathy. Simultaneously, the foot process fusion and fall-off were partially reversed after TSJ treatment. TSJ or metformin markedly upregulated the level of nephrin and podocin, accompanied by evident enhancement of podocyte autophagy and activation of p-AMPK/p-ULK1 signaling in the diabetic nephropathy. Therefore, TSJ may enhance podocyte autophagy to relieve diabetic nephropathy through modulation of p-AMPK/p-ULK1 signaling, which has important application prospects in the clinical treatment of diabetic kidney damage in the future.

A Computational Framework to Identify Transcriptional and Network Differences between Hepatocellular Carcinoma and Normal Liver Tissue and Their Applications in Repositioning Drugs.

Hepatocellular carcinoma (HCC) is one of the most common and lethal malignancies worldwide. Although there have been extensive studies on the molecular mechanisms of its carcinogenesis, FDA-approved drugs for HCC are rare. Side effects, development time, and cost of these drugs are the major bottlenecks, which can be partially overcome by drug repositioning. In this study, we developed a computational framework to study the mechanisms of HCC carcinogenesis, in which drug perturbation-induced gene expression signatures were utilized for repositioning of potential drugs. Specifically, we first performed differential expression analysis and coexpression network module analysis on the HCC dataset from The Cancer Genome Atlas database. Differential gene expression analysis identified 1,337 differentially expressed genes between HCC and adjacent normal tissues, which were significantly enriched in functions related to various pathways, including α-adrenergic receptor activity pathway and epinephrine binding pathway. Weighted gene correlation network analysis (WGCNA) suggested that the number of coexpression modules was higher in HCC tissues than in normal tissues. Finally, by correlating differentially expressed genes with drug perturbation-related signatures, we prioritized a few potential drugs, including nutlin and eribulin, for the treatment of hepatocellular carcinoma. The drugs have been reported by a few experimental studies to be effective in killing cancer cells.

High-power, ultra-broadband supercontinuum light generated in a single-mode fiber pumped with a nanosecond passively Q-switched microchip laser.

The compact, high-power, broadband continuum sources are extremely needed for developing portable instruments for various applications such as optical coherence tomography, high-resolution spectroscopy, and so on. Here, we develop a compact high-power, ultra-broadband supercontinuum (SC) light source in a single-mode fiber (SMF) pumped with a Yb:YAG/Cr4+:YAG passively Q-switched microchip laser oscillating at 1030 nm. The spectral bandwidth of the SC light is over 1150 nm covering from 600 to 1750 nm. The maximum average output power is 181.8 mW at an input pump power of 880 mW. The optical efficiency is 20.6%, and the net conversion efficiency is as high as 51.6% with respect to the pump power coupled into the fiber. The ultra-broadband spectrum of the SC generated in the SMF is caused by the intermodal four-wave mixing (IMFWM) and cascade stimulated Raman scattering effects. Various transverse modes have been experimentally observed in SC beam generated in the SMF. Wavelength-dependent transverse modes propagating in the SMF participating in the IMFWM process dramatically expand the spectral range in the visible region. The experimental results are basically consistent with the theoretical simulations of broadband SC generated in the SMF through the IMFWM process.

Circulating CD137+ CD8+ T cells accumulate along with increased functional regulatory T cells and thoracic tumour burden in lung cancer patients.

CD137 is a promising target for immunostimulation strategies against cancer. Previous studies showed that CD137+ CD8+ T cells are enriched in antitumour effector T cells in both preclinical tumour models and cancer patients, but to date, such T cells in the blood of lung cancer patients have not been sufficiently investigated. In this study, circulating antigen-activated CD8+ T cell subsets, identified as CD137+ CD8+ or PD-1+ (programmed cell death protein 1) CD8+ , and regulatory T cells (Treg), identified as CD4+ CD25+ CD127low/- , in 40 untreated lung cancer patients and in 49 age- and sex-matched healthy controls (HCs) were assessed by flow cytometry. Results were evaluated for associations with lung cancer patient clinical characteristics. Correlations between antigen-activated CD8+ T cells and effector Treg (CTLA-4+ [cytotoxic T-lymphocyte antigen 4] CD4+ CD25+ CD127low/- ) were also investigated. Higher percentages of PD-1+ , CD137+ and PD-1+ CD137+ amongst CD8+ T cells were observed in lung cancer patients compared with HCs. The percentages of CD137+ CD8+ and PD-1+ CD137+ CD8+ T cell subsets amongst CD8+ T cells were positively correlated with thoracic tumour burden and were strongly positively correlated with the percentage of effector Treg subset. Smoking patients harboured higher percentages of the PD-1+ CD8+ T cell subset compared with non-smoking patients. This study demonstrated that circulating antigen-activated CD8+ T cells accumulated in lung cancer patients along with increased effector Treg and thoracic tumour burden. These findings aid a better understanding of immune-host interactions in lung cancer patients using peripheral blood, and further support immunotherapeutic intervention strategies using combination therapy for differential control of Treg and activation of tumour-specific effector T cells.

Polymorphisms in CLDN1 are associated with age and differentiation of triple-negative breast cancer patients.

Purpose: Triple-negative breast cancer (TNBC) is a highly heterogeneous disease. It is very important to explore novel biomarkers to better clarify the characteristics of TNBC. It has been reported that polymorphisms in claudin 1 (CLDN1) are associated with risk of several cancers. But till now, there is no report about these polymorphisms and TNBC. Patients and methods: Between January 2004 and December 2013, 267 patients with stage I-III primary TNBC were included in our study. We investigated the association between polymorphisms in CLDN1 gene and clinicopathological characteristics or survival of these patients. We used Haploview 4.2 software to identify Tag single nucleotide polymorphisms (SNPs). MassARRAY MALDI-TOF System was used for genotyping. Results: We found that rs10513846 GA genotype was associated with older age [P=0.013, hazard ratios (HR) = 2.231, 95% confidence interval (CI): 1.186-4.195]. Rs10513846 AA genotype carriers were more likely to develop grade 3 tumors (P=0.005, HR = 2.889, 95% CI: 1.389-6.007). And rs9283658 genotypes were also related to grade, more patients with grade 3 tumors were rs9283658 CC genotype carriers (P=0.023, HR = 0.446, 95% CI: 0.222-0.894). There was no association between polymorphisms in CLDN1 and survival of TNBC patients. After multivariate analysis, tumor size (P=0.021, HR = 3.146, 95% CI: 1.185-8.354) and lymph node status (P<0.001, HR = 10.930, 95% CI: 3.276-36.470) were demonstrated to be independent prognostic factors. Conclusion: We first demonstrated that polymorphisms in CLDN1 gene were associated with age and differentiation of TNBC patients.

Investigating the mechanism by which SMAD3 induces PAX6 transcription to promote the development of non-small cell lung cancer.

BACKGROUND: This study investigated the function of SMAD3 (SMAD family member 3) in regulating PAX6 (paired box 6) in non-small cell lung cancer. METHODS: First, qRT-PCR was employed to detect SMAD3 expression in cancer tissues along with normal tissues and four cell lines, including BEAS-2B, H125, HCC827 and A549 cells. SMAD3 was knocked down by small interference RNA (siRNA), and then its expression was determined via qRT-PCR and Western blot analysis. The correlation between SMAD3 and PAX6 was determined by double luciferase reporter experiments and chromatin immunoprecipitation (ChIP) assay. Cell viability was evaluated by CCK-8 and colony forming assays, while cell migration and invasion were detected by Transwell analysis. RESULTS: SMAD3 and PAX6 were upregulated in lung cancer tissues and cancer cells. Knocking down SMAD3 and PAX6 by transfection with siRNAs specifically suppressed the expression of SMAD3 and PAX6 mRNA and protein levels. SMAD3 could promote PAX6 transcriptional activity by binding to its promoter. Reduced expression of SMAD3 led to the downregulation of PAX6 mRNA and protein levels along with decreased cell migration, invasion, proliferation and viability in A549 and HCC827 cells. PAX6 overexpression altered the si-SMAD3-induced inhibition of cell migration, invasion, proliferation and viability in A549 and HCC827 cells. Additionally, PAX6 knockdown alone also repressed the cell migration, invasion, proliferation and viability of the cell lines. CONCLUSIONS: SMAD3 promotes the progression of non-small cell lung cancer by upregulating PAX6 expression.

Mechanism of TangGanJian on nonalcoholic fatty liver disease with type 2 diabetes mellitus.

CONTEXT: TangGanJian (TGJ) has a curative effect in the clinical treatment of nonalcoholic fatty liver disease (NAFLD) with type 2 diabetes mellitus (T2DM), while the mechanism involved in the treatment process remains unclear. OBJECTIVE: This study details the mechanism of TGJ on the treatment of NAFLD with T2DM. MATERIALS AND METHODS: NAFLD was induced in T2DM rat model. Male Wistar rats were assigned into six groups: Group I (control), Group II (model), Group III (pioglitazone, 0.5 mg/kg), Group IV (high dose of TGJ, 24.8 g/kg), Group V (middle dose of TGJ, 12.4 g/kg) and Group VI (low dose of TGJ, 6.2 g/kg). All rats in each group were treated with the corresponding drugs by gavage for 8 weeks. Haematoxylin and eosin analysis was conducted. The indicators of inflammatory and oxidative stress were analysed utilizing one-way ANOVA. RESULTS: The contents of TNF-α (15.794 ± 3.302 pg/mL), IL-6 (76.801 ± 8.491 pg/mL), IL-1ß (100.101 ± 13.150 pg/mL), CRP (1.052 ± 0.079 pg/mL) and MDA (3.972 ± 0.159 pg/mL) were obviously elevated in NAFLD with T2DM rats compared to controls. Except for the IL-6, the levels of other markers declined in a dose-dependent manner after treatment with TGJ. The SOD (14.139 ± 1.479 U/mgprot) and GSH-PX (81.511 ± 5.276 U/mgprot) levels significantly decreased in NAFLD with T2DM rats, while the levels of these indicators increased after treatment with TGJ. CONCLUSIONS: TGJ may be a therapy for the NAFLD with T2DM rats by modulating the inflammatory response and the oxidative stress capacity.

Tangganjian decoction ameliorates type 2 diabetes mellitus and nonalcoholic fatty liver disease in rats by activating the IRS/PI3K/AKT signaling pathway.

AIM: Previous clinical studies have demonstrated that tangganjian (TGJ), a modern Chinese prescribed medicine, has a clinical effect in the treatment of type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver disease (NAFLD). Our study aimed to investigate whether the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway is involved in this therapeutic effect. MATERIALS AND METHODS: T2DM and NAFLD rat models were constructed and treated with three different concentrations of TGJ. Pioglitazone was used as a positive control, along with the model and normal groups. For analyses, blood and livers were collected. Levels of glucose and lipid metabolism indicators, including fasting insulin and total cholesterol, were determined. The expression levels of insulin receptor substrate (IRS), PI3K, and AKT were also determined by western blotting and immunohistochemistry. Liver tissues were stained with hematoxylin & eosin. RESULTS: In the high-dose TGJ-treated and positive groups, there was a significant increase in the HDL-C level and decreases in the levels of the fasting blood glucose, 2 h postprandial blood glucose, fasting insulin, triglyceride, total cholesterol, and low-density lipoprotein cholesterol, along with a significant increase in the expression of IRS, PI3K, and AKT in the liver. TGJ could also attenuate or counteract the effects of T2DM and NAFLD in the liver lobules. CONCLUSION: A high concentration of TGJ can improve glucose and lipid metabolism by activating the IRS/PI3K/AKT signaling pathway.

Well-differentiated fetal adenocarcinoma of the lung: clinicopathologic features of 45 cases in China.

OBJECTIVE: Well-differentiated fetal adenocarcinoma (WDFA) is a rare pulmonary carcinoma with low malignancy and favorable prognosis. All cases were collected, analyzed and summarized to better understand this disease. METHODS: We used the keywords "fetal adenocarcinoma" and "epithelial pulmonary blastoma (EPB)" to search WANFANG MED ONLINE, CNKI and NCBI PUBMED for cases reported by Chinese authors from 1987 to July 2015. RESULTS: A total of 64 cases reported in China were reviewed, and the details of the clinicopathological features of 45 cases were summarized. Among these 45 patients, 23 (23/45, 51.1%) patients were male and 22 (22/45, 48.9%) patients were female. The mean age at diagnosis was 35 ± 15 years old (range, 6-72 years old) with a bimodal peak in the second and third decades. Furthermore, 24 tumors (24/31, 77.4%) were found to have progressed past stage I, while only three (3/45, 6.7%) tumors had lymph nodes metastases. These tumor cells were 100% reactive for keratin, ß-catenin, Napsin A and PDGFRα when stained by these antibodies. Better survival could be obtained if the metastatic tumor is removed in some patients with metastases. Four (4/31, 12.9%) patients died due to their tumors. CONCLUSIONS: WDFA is very different to conventional adenocarcinoma in clinicopathology. It prefers to occur in the second and third decades. Lymph node metastasis is infrequent. Beta-catenin may be a potential marker for disease. Surgery is the best therapy method if the technology is feasible.

Psychotic-like experiences and correlation with childhood trauma and other socio-demographic factors: A cross-sectional survey in adolescence and early adulthood in China.

Psychotic-like experiences (PLEs) in adolescence are found to be risk factors for later mental disorders. Previous research has also found that childhood trauma has a positive correlation with mental health problems. However, few studies have focused on the relationship between them, especially in adolescence and early adulthood. A total of 9122 students (age between 10 and 23.3) were surveyed and assessed with the positive and depressive subscales of the Community Assessment of Psychic Experiences and the Trauma History Questionnaire. A total of 20.7% students experienced frequent PLEs, 17.5% had frequent delusional experiences, and 7.6% had frequent hallucinatory experiences. Only a small portion of this sample experienced frequent PLEs, associated with more types of PLEs, more distress, and more depressive experiences. Several socio-demographic factors were associated with frequent PLEs in this sample, which could be further examined in future prevention studies. Students with frequent PLEs experienced significantly higher impact from trauma events, both at the time of the events and in the present, indicating a possible reciprocal effect between childhood trauma and PLEs. The impact of childhood trauma played an important role in the relationship between childhood trauma and PLEs.

Task and resting-state fMRI studies in first-episode schizophrenia: A systematic review.

In the last two decades there has been an increase on task and resting-state functional Magnetic Resonance Imaging (fMRI) studies that explore the brain's functional changes in schizophrenia. However, it remains unclear as to whether the brain's functional changes during the resting state are sensitive to the same brain regions during task fMRI. Therefore, we conducted a systematic literature search of task and resting-state fMRI studies that investigated brain pathological changes in first-episode schizophrenia (Fleischhacker et al.). Nineteen studies met the inclusion criteria; seven were resting state fMRI studies with 371 FES patients and 363 healthy controls and twelve were task fMRI studies with 235 FES patients and 291 healthy controls. We found overlapping task and resting-state fMRI abnormalities in the prefrontal regions, including the dorsal lateral prefrontal cortex, the orbital frontal cortex and the temporal lobe, especially in the left superior temporal gyrus (STG). The findings of this systematic review support the frontotemporal hypothesis of schizophrenia, and the disruption in prefrontal and STG might represent the pathophysiology of schizophrenia disorder at a relatively early stage.

Psychotic-like experiences, trauma and related risk factors among "left-behind" children in China.

BACKGROUND: Large scale migration of workers due to wage differences across regions of China has separated millions of children, called "left-behind children" from their parents. Psychotic-like experiences (PLEs) are thought to be associated with childhood deprivation and may predict later psychotic disorders but have not been studied in this potentially vulnerable population. METHODS: Data were collected from representative samples of students in thirteen middle schools in the Xiangxi region and Changsha city of Hunan province (N=6623), of whom 1360 (21.3%) were "left-behind" children. Children were surveyed with the positive frequency subscales of the Community Assessment of Psychic Experiences and the Trauma History Questionnaire child version. RESULTS: More "left-behind" children reported experiencing PLEs than others. They also scored higher on the overall frequency of PLEs, severity of childhood trauma, and the subjectively perceived psychological impact of trauma both at the time of the events and at present. Compared with "left-behind" children raised by a parent or by grandparents, those raised by others reported suffering more severe impact both at the time of the events and at present. Among "left-behind" children trauma history was the most important correlate of PLEs followed by Han ethnicity, older age, and not having a stable family income. CONCLUSION: "Left-behind" children are at higher risk for PLEs and suffer more traumatic events than other Chinese children. Interventions that reduce trauma risk and improve relationships with caregivers may be helpful, especially for older "left-behind" children.

[Serum CYFRA21-1 is Correlated with the Efficacy of Epidermal Growth Factor Receptor-tyrosine Kinase Inhibitor in Non-small Cell Lung Cancer Patients Harboring EGFR Mutations].

BACKGROUND: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are the standard first-line treatment regimen for EGFR mutated non-small cell lung cancer (NSCLC) patients. However, the efficacy of EGFR-TKIs widely varies. The aim of this study is to determine whether the pretreatment serum cytokeratin-19 fragments (CYFRA21-1) and carcinoembryonic antigen (CEA) are associated with the efficacy of EGFR-TKIs in EGFR-mutated NSCLC patients. METHODS: We retrospectively enrolled 194 NSCLC patients harboring EGFR mutations who received EGFR-TKIs. Clinical characteristics were collected, and the relation between the efficacy of EGFR-TKIs and pretreatment serum CYFRA21-1 and CEA was analyzed. RESULTS: In all cases, progression-free survival (PFS) in patients with high CYFRA21-1 level was significantly shorter than PFS in patients with normal CYFRA21-1 (7.0 vs 11.9 months, P<0.001). Overall survival (OS) in patients with high CYFRA21-1 was significantly shorter than in the normal-CYFRA21-1 group (12.6 vs 28.0 months, P<0.001). In adenocarcinoma patients, PFS in the high-CYFRA21-1 level group was significantly shorter than in patients with normal CYFRA21-1 (7.0 vs 12.0 months, P<0.001). OS in patients with high CYFRA21-1 was significantly shorter than that in the normal-CYFRA21-1 group (13.1 vs 28.1 months, P<0.001). Among squamous carcinoma patients, CYFRA21-1 level did not affect survival. No significant difference in PFS and OS was observed between patients with high CEA and patients with normal CEA. CONCLUSIONS: EGFR-mutated patients with high CYFRA21-1 had significantly shorter PFS and OS than patients with normal CYFRA21-1 after receiving EGFR-TKIs. Pretreatment serum CYFR21-1 level was a predictive marker of EGFR-TKI treatment in EGFR-mutated NSCLC patients.
