Abstract
OBJECTIVE To investigate the role of phosphatidylinositol-3-kinase protein kinase B (PI3K/Akt) signaling pathway in the apoptosis of H1299 lung cancer cells induced by epigallocatechin gallate (EGCG). MATERIALS AND METHODS H1299 lung cancer cells were treated with EGCG at a dose of 10 µM, 20 µM, and 40 µM, respectively. Cell culture was performed for 72 h and then: 1, cell proliferation was detected by MTT assay; 2, cell apoptosis rate was detected by flow cytometry; 3, expression of Caspase-3, Bax, and Bcl-2 was detected by Western blot; 4, expression of PI3K, p-PI3K, Akt, and p-Akt was detected by Western blot. RESULTS The proliferation of H1299 cells was significantly inhibited 72 h after treatment with different doses of EGCG, and cell apoptosis rate was significantly increased (p<0.05). Compared with those in the control group, expression of PI3K and Akt in the lung cancer cells H1299 after EGCG treatment showed no significant differences (p>0.05), while expression levels of p-PI3K and p-Akt were significantly reduced (p<0.05). CONCLUSIONS EGCG can inhibit the proliferation and induce apoptosis of H1299 lung cancer cells, and the effect is related to the inhibition of the activation of PI3K/Akt signaling pathway.

Abstract
OBJECTIVE We conducted this study to analyze the EEG abnormalities of cognitive impairment and epileptic seizures in patients with epilepsy, as well as to investigate the application value of EEG in the diagnosis of epilepsy with cognitive impairment. PATIENTS AND METHODS 62 cases of patients that were admitted to our hospital for the first diagnosis as status epilepticus were selected. Of those, 20 cases were accompanied by cognitive impairment. The America Biology Graphene type 24 leads channel video EEG was applied to monitor staging, index, frequency, and distribution range of epileptic discharge. The revised Wechsler Adult Intelligence Scale-Revised in China (WAIS-RC) and Wechsler Memory Scale-Revised in China (WMS-RC) were adopted to test cognitive function. RESULTS The epileptic discharge index, discharge frequency and discharge distribution range of the conscious period, sleep I-II period and sleep III-IV period of epilepsy with the cognitive impairment group were evidently higher than those of epilepsy without cognitive impairment group. The differences were statistically significant (p<0.05). Intelligence Quotient (IQ) and Memory Quotient (MQ) level of the cognitive impairment group were the lowest in sleep III-IV period, with the next being the sleep I-II period; the highest was the conscious period, and the differences were statistically significant (p<0.05). With an increase of the epileptic discharge index, the discharge range, IQ and MQ level of cognitive impairment group decreased; differences were statistically significant (p<0.05). Therefore, the discharge index, frequency, and distribution range of epileptic discharge of epilepsy with cognitive impairment in different periods differed from epilepsy patients without cognitive impairment. According to the extent of cognitive impairment in different stages, discharge index, frequency, and distribution range were also different. CONCLUSIONS The 24 h video EEG, which was used to monitor epileptic discharge characteristics, has a great application value for early identification of epilepsy with cognitive impairment.

Abstract
Filial piety (FP) was formerly a Confucian concept that specifies how children should treat their elders. In recent years, some psychologists have postulated that there are considerable overlaps between Chinese FP and notions found in other cultures. They have redefined FP as a contextualized personality emphasizing the psychological schema of parent-child interaction so that it fits universal cultural contexts. Based on this theory construction, this study aimed to examine the effects of reciprocal FP and authoritarian FP on life satisfaction and the mediating roles of individuating autonomy and relating autonomy therein. To do so, we recruited and surveyed 360 high school students in China. Subsequently, a mediation model based on the Dual Filial Piety Model and previous studies was tested. Results demonstrate that reciprocal FP predicted life satisfaction positively and that both individuating autonomy and relating autonomy played significant mediating roles in the relationship between reciprocal FP and life satisfaction. Moreover, authoritarian FP had a negative indirect effect on satisfaction through the mediating role of individuating autonomy, while authoritarian FP had a positive indirect influence on satisfaction through the mediating role of relating autonomy. The theoretical and practical implications of these findings are discussed.

Abstract
OBJECTIVE To explore the role of microRNA-15b in diabetic retinopathy (DR) and its underlying mechanism. MATERIALS AND METHODS Diabetic retinopathy rat model was first constructed. Retinal endothelial cells (EC) and retinal pericytes (RP) in DR rats were extracted. The mRNA expression of microRNA-15b in EC and RP cells was detected by qRT-PCR (quantitative Real Time-Polymerase Chain Reaction). Protein expression of insulin receptor substrate 1 (IRS-1) in EC and RP cells was detected by Western blot. After altering microRNA-15b expression by plasmid transfection, cell viability was detected by CCK-8 (cell counting kit-8) assay. Furthermore, the target gene of microRNA-15b was predicted by TargetScan analysis and the binding condition was verified by luciferase reporter gene assay. Finally, rescue experiments were carried out to explore the regulatory effect of microRNA-15b on IRS-1. RESULTS MicroRNA-15b was lowly expressed, whereas IRS-1 was highly expressed in EC and RP cells. After overexpression of microRNA-15b, viabilities of EC and RP cells were decreased and β-catenin expression was inhibited. TargetScan predicted that IRS-1 was the downstream gene of microRNA-15b, which was further verified by luciferase reporter gene assay. Rescue experiments indicated that microRNA-15b was capable of regulating IRS-1 via Wnt/β-catenin signaling pathway. CONCLUSIONS MicroRNA-15b participates in the development of diabetic retinopathy by targeting IRS-1 via Wnt/β-catenin signaling pathway.

Abstract
OBJECTIVE In Alzheimer's disease (AD), astrocytes are generally found in the surrounding of senile plaques participating in the production of phagocytosis and the removal of toxic compounds such as Aβ. This study aimed at investigating the effect of Aβ1-42 on astrocytes. MATERIALS AND METHODS Cellular viability of primary cultured astrocytes was analyzed using CCK-8 assay. Quantitative Real-time PCR was used to assess the mRNA expression of JNK and AP-1. The proteins of JNK/AP-1 pathway were investigated using Western blot. RESULTS Our findings showed that Aβ1-42 inhibited cell viability and promoted apoptosis in astrocytes in primary culture. Additionally, Aβ1-42 increased the mRNA expression level of AP-1, but had no effect on the expression of JNK. Furthermore, Aβ1-42 increased the protein expression of p-JNK, p-c-jun and Fra-1 and the ratio of p-c-jun/c-jun and p-JNK/JNK. CONCLUSIONS We showed that Aβ1-42 promoted cell apoptosis in astrocytes in primary culture. Furthermore, Aβ1-42 activated JNK/AP-1 pathway through promoting the phosphorylation of JNK, c-jun and Fra-1 expression, then inducing cell apoptosis.

Abstract
OBJECTIVE To identify the functioning mode of miR-378 on non-small cell lung cancer (NSCLC) and provide therapeutic targets for NSCLC. PATIENTS AND METHODS Expression levels of miR-378 in human NSCLC tissue samples and NSCLC-derived cell lines were measured by using quantitative Real-time polymerase chain reaction (PCR). Cell proliferation capacity was assessed by methyl thiazolyl tetrazolium (MTT) assay and colony formation assay. Cell apoptosis and cell cycle distribution were identified by flow cytometry. Downstream target gene was confirmed by using luciferase and Western blotting assays. RESULTS MiR-378 was significantly elevated in NSCLC tissues when compared with para-carcinoma tissues (n=42). Decreased-miR-378 could attenuate cell proliferation capacity, as well as promoted cell apoptosis and induced cell cycle arrest at G0/G1 phase. FOXG1 was chosen as the target gene of miR-378 by bioinformatics analysis and luciferase reporter assay. Moreover, restoration of miR-378 could impair the tumor suppression role of downregulated-miR-378 on NSCLC growth. CONCLUSIONS Decreased-miR-378 exerted tumor-suppressive effects on NSCLC growth via targeting FOXG1 in vitro, which provided an innovative and candidate target for diagnosis and treatment of NSCLC.

Abstract
The current study investigated the relationship between gratitude, internalizing and externalizing problem behaviors, along with the mediating roles of positive and negative coping styles therein. A sample of 589 Chinese adolescents completed the Gratitude Questionnaire (GQ-6), the Simplified Coping Style Questionnaire (SCSQ), the Irritability, Depression, and Anxiety Scale (IDAS), and the Aggression Questionnaire (AQ). Results of structural equation modeling showed that (1) the total effects of gratitude on both internalizing and externalizing problem behaviors were all significant and (2) both positive and negative coping styles mediated the links between gratitude and two types of problem behaviors. Thus, cultivating gratitude and developing adaptive coping style may help adolescents rectify problem behaviors.

Abstract
Alpha-fetoprotein (AFP) is a well-known tumor marker of hepatic carcinoma and yolk sac tumor. Alpha-fetoprotein producing gastric carcinoma (AFPGC) is a rare type of gastric cancer with high malignancy and poor prognosis, which make it different from other types of gastric cancer. This rare gastric cancer patient subgroup is likely frequently misdiagnosed which may be related to lack of knowledge of the disease. The purpose of this article is to summarize the mechanism of AFP positive gastric cancer, classification, biological behavior and treatment, in order to assist clinical practitioners to detect AFPGC earlier and treat it better. Previous studies have showed that AFPGC has a complex pathophysiology mechanism. AFPGC is more aggressive and characterized by stronger proliferation, neovascularization, lymphatic invasion and distant metastasis. Furthermore, so far there has been no standard treatment for patients with AFPGC. Nevertheless, our present study summarizes some effective treatments based on previous research outcome. In conclusion, the present study demonstrates that the importance of detecting AFP routinely in serum and tissues in gastric cancer cases, which will greatly improve the diagnosis rate of AFPGC, and in regards to treatment, surgery, chemotherapy, targeted therapy and interventional treatment may have positive impacts on AFPGC treatment outcome. However, further study with a larger sample is required to confirm the reliability and validity of these methods.

Abstract
Objective:To explore the application of narrowband imaging (NBI) in overcoming the microvascular pattern hidden under the plaque of vocal fold leukoplakia. Method:According to the morphology of intraepithelial papillary capillary loops (IPCL) around the plaque of vocal cord leukoplakia under NBI endoscopy,89 patients with microvascular morphology covered by plaque were divided into different groups. Subepithelial cordectomy was performed in 20 cases of benign group, subligamental cordectomy was performed in 45 cases of suspected malignant group, and transmuscular cordectomy was performed in 24 cases of malignant group, respectively. The lesions of vocal fold were biopsied with suspension micro-laryngoscope, and pathological examinations were also observed. Result:Pathological diagnoses showed that there were 10 cases of squamous epithelial hyperplasia, 8 cases of mild dysplasia, 21 cases of moderate dysplasia, 41 cases of severe dysplasia and carcinoma in situ, and 9 cases of invasive cancer, respectively. Spearman's analysis showed that there was a stronge positive correlation between the microvascular pattern of peripheral regions surrounding the plaque by NBI endoscopy and malignant degree of pathological classification(r=0.725, P<0.01). Conclusion:NBI endoscopy can overcome the "umbrella effect" of vocal cord leukoplakia. The microvascular morphology of the mucosa around the leukoplakia has a good correlation with final pathological diagnoses, and NBI endoscopy is helpful to determine the biopsy depth of the vocal cord leukoplakia.

Abstract
AIMS Custom flange acetabular components (CFACs) are a patient-specific option for addressing large acetabular defects at revision total hip arthroplasty (THA), but patient and implant characteristics that affect survivorship remain unknown. This study aimed to identify patient and design factors related to survivorship. PATIENTS AND METHODS A retrospective review of 91 patients who underwent revision THA using 96 CFACs was undertaken, comparing features between radiologically failed and successful cases. Patient characteristics (demographic, clinical, and radiological) and implant features (design characteristics and intraoperative features) were collected. There were 74 women and 22 men; their mean age was 62 years (31 to 85). The mean follow-up was 24.9 months (sd 27.6; 0 to 116). Two sets of statistical analyses were performed: 1) univariate analyses (Pearson's chi-squared and independent-samples Student's t-tests) for each feature; and 2) bivariable logistic regressions using features identified from a random forest analysis. RESULTS Radiological failure and revision rates were 23% and 12.5%, respectively. Revisions were undertaken at a mean of 25.1 months (sd 26.4) postoperatively. Patients with radiological failure were younger at the time of the initial procedure, were less likely to have a diagnosis of primary osteoarthritis (OA), were more likely to have had ischial screws in previous surgery, had fewer ischial screw holes in their CFAC design, and had more proximal ischial fixation. Random forest analysis identified the age of the patient and the number of locking and non-locking screws used for inclusion in subsequent bivariable logistic regression, but only age (odds ratio 0.93 per year) was found to be significant. CONCLUSION We identified both patient and design features predictive of CFAC survivorship. We found a higher rate of failure in younger patients, those whose primary diagnosis was not OA, and those with more proximal ischial fixation or fewer ischial fixation options.

Abstract
OBJECTIVE To investigate the expression of long-chain non-coding RNA ROR in prostate cancer (PCa), and to further study its possible underlying mechanisms in prostate cancer. PATIENTS AND METHODS Quantitative Real-time polymerase chain reaction (qRT-PCR) was performed to detect the level of lncRNA ROR in 42 pairs of PCa tissues and adjacent normal tissues, and the correlation between ROR level and PCa pathological parameters was also evaluated. Besides, ROR expression in PCa cells was further verified by qRT-PCR, and ROR knockdown model was constructed using lentivirus in PCa cell lines including PC-3 and Lncap. Cell counting kit-8 (CCK-8), transwell invasion and cell scratch assay were used to analyze the effect of ROR on the biological function of PCa cells and explore its underlying mechanism. RESULTS QRT-PCR results demonstrated that ROR levels in PCa tissues were notably higher than that in normal ones, and the difference was statistically significant. Compared with patients with lowly-expressed ROR, patients with high ROR level had relatively more advanced tumor stage, higher incidence of lymph node or distant metastasis. Similarly, compared with negative control group, the cell proliferation, invasion and metastasis ability of the ROR knockdown group was significantly decreased. In addition, qRT-PCR results indicated that the expression of Akt, the key protein in the Akt signaling pathway, was significantly reduced in si-ROR cell lines. Furthermore, rescue experiment revealed that there was a mutual regulation between ROR and Akt. CONCLUSIONS LncRNA ROR expression is strikingly increased in PCa tissues or cells, and is considerably associated with PCa stage, lymph node and distant metastasis. Additionally, LncRNA ROR may promote PCa cell proliferation, invasion and migration by regulating Akt.

Abstract
The aim of this study was to evaluate the dose-dependent effects of a hydroxy-analog of selenomethionine (HMSeBA) on rumen fermentation, apparent nutrient digestibility, and total selenium absorption in mid-lactation dairy cows, and to compare the effects with those of sodium selenite (SS). Fifty mid-lactation dairy cows with similar milk yields, days in milk, and parity were randomly assigned to 1 of 5 treatments according to a randomized complete block design. The cows were fed a basal diet containing 0.06 mg/kg dry matter (DM) of Se (control) or the same basal diet supplemented with SS, yielding 0.3 mg of Se/kg of DM (SS-0.3), or HMSeBA, yielding 0.1, 0.3, or 0.5 mg of Se/kg of DM (SO-0.1, SO-0.3, and SO-0.5, respectively), during the experimental period. The final content of Se in control, SS-0.3, SO-0.1, SO-0.3, and SO-0.5 was 0.06, 0.34, 0.15, 0.33, and 0.52 mg of Se/kg of DM. The experiment lasted for 10 wk, with a pretrial period of 2 wk. Supplementation with HMSeBA altered rumen fermentation by linearly increasing total volatile fatty acids and the molar proportions of propionate and butyrate but decreasing rumen pH, ammonia content, and the ratio of acetate to propionate. Compared with SS, HMSeBA enhanced the molar proportion of propionate in the rumen and the apparent digestibility of crude protein, neutral detergent fiber, acid detergent fiber, and selenium. We demonstrated that HMSeBA promoted rumen fermentation, apparent nutrient digestibility, and selenium absorption, implying that HMSeBA has a greater apparent absorption than SS.

Abstract
We present results for the ionic structure in hydrocarbons (polystyrene, polyethylene) that were shock compressed to pressures of up to 190 GPa, inducing rapid melting of the samples. The structure of the resulting liquid is then probed using in situ diffraction by an x-ray free electron laser beam, demonstrating the capability to obtain reliable diffraction data in a single shot, even for low-Z samples without long range order. The data agree well with ab initio simulations, validating the ability of such approaches to model mixed samples in states where complex interparticle bonds remain, and showing that simpler models are not necessarily valid. While the results clearly exclude the possibility of complete carbon-hydrogen demixing at the conditions probed, they also, in contrast to previous predictions, indicate that diffraction is not always a sufficient diagnostic for this phenomenon.

Abstract
Objective: To investigate and compare the sensitivities of early childhood caries detection by using international caries detection and assessment system (ICDAS)-Ⅱ and WHO criteria. Methods: A total of 449 3-year-old children from four day care kindergartens in Beijing were enrolled in this study. Both ICDAS-Ⅱ and WHO criteria were used to assess the prevalence of caries in the given subjects. The decayed, missing, and filled teeth (dmft) index scores were calculated. In ICDAS-Ⅱ system, four cut-off points (D1, D2, D3 and D4) were employed to differentiate sound and decayed teeth: D1 (score 0 as sound, scores 1-6 as caries); D2 (0-1 sound, 2-6 caries); D3 (0-2 sound, 3-6 caries) and D4 (0-3 sound, 4-6 caries). SPSS software was used to analyze the data to decide the significance of differences. Results: The caries prevalence using ICDAS-Ⅱ were 76.6% (344/449), 71.3% (320/449), 52.8% (237/449) and 46.1% (207/449) for D1 to D4, respectively; the corresponding mean dmft scores were 4.95±4.85, 4.41±4.77, 2.54±3.69 and 1.97±3.10. The sites with highest caries prevalence were occlusal surface of mandibular molars in groups of D1 and D2 and proximal surface of maxillary anterior teeth in groups D3 and D4. In contrast, the caries prevalence was 48.8% (219/449) and the mean dmft was 2.27±3.54 when using WHO criteria, significantly lower than the detection rates by using ICDAS-Ⅱ (D1-D2) (P=0.00). This suggested that ICDAS-Ⅱ system was a more sensitive method in detecting early childhood caries. Conclusions: ICDAS-Ⅱ system might be superior in detection of incipient caries and be of specific value in prevention of early childhood caries.

Abstract
We describe a setup for performing inelastic X-ray scattering and X-ray diffraction measurements at the Matter in Extreme Conditions (MEC) endstation of the Linac Coherent Light Source. This technique is capable of performing high-, meV-resolution measurements of dynamic ion features in both crystalline and non-crystalline materials. A four-bounce silicon (533) monochromator was used in conjunction with three silicon (533) diced crystal analyzers to provide an energy resolution of ∼50 meV over a range of ∼500 meV in single shot measurements. In addition to the instrument resolution function, we demonstrate the measurement of longitudinal acoustic phonon modes in polycrystalline diamond. Furthermore, this setup may be combined with the high intensity laser drivers available at MEC to create warm dense matter and subsequently measure ion acoustic modes.
