Background: This study was conducted to determine DEPDC1 expression in hepatocelluar carcinomas (HCCs) and to reveal its potential role in diagnosis and prognosis of affected patients. Materials and Methods: DEPDC1 expression at the mRNA level was detected by quantitative real-time PCR (qRT-PCR) in 205 cases of HCC and paired adjacent normal liver tissues, and by semi-quantitative RT-PCR in 20 cases. Survival curves were obtained by using Kaplan-Meier method and Log-rank test. Independent predictors associated with regard to disease free survival (DFS) and overall survival (OS) were identified using the Cox proportional hazard model. Results: High DEPDC1 mRNA levels were detected in 144 out of 205 cases (70.24%) of HCC, significantly associated with clinicopathological parameters, including tumor size (${\geq}4cm$), alpha-fetoprotein (${\geq}100ng/ml$), B-C of BCLC stage and recurrence. Kaplan-Meier survival analysis revealed that HCC patients with high DEPDC1 expression had poor OS and DFS. Multivariate analysis demonstrated that high DEPDC1 expression was an independent predictor for OS (HR=1.651; 95% 95%CI, 1.041-2.617; p=0.033) and DFS (HR=1.583; 95%CI, 1.01-2.483; p=0.045). Conclusions: Our results indicate DEPDC1 might be a novel diagnostic marker and an independent prognostic predictor for HCC patients.

To investigate the expression intensity and prognostic significance of TGF-${\beta}1$ protein in non-small cell lung cancer (NSCLC), immunohistochemistry was carried out in 194 cases of NSCLC and 24 cases of normal lung tissues by SP methods. The PU (positive unit) value was used to assess the TGF-${\beta}1$ protein expression in systematically selected fields under the microscope with Leica Q500MC image analysis. We found that the TGF-${\beta}1$ PU value was nearly two-fold higher in NSCLC than in normal lung tissues (p=0.000), being associated with TNM stages (p=0.000) and lymph node metastases (p=0.000), but not to patient age, gender, smoking history, tumor differentiation, histological subtype and tumor location (P>0.05). Univariate analysis indicated that patients with high TGF-${\beta}1$ protein expression and lymph node metastases demonstrated a poor prognosis (both p=0.000,). Multivariate analysis showed that TGF-${\beta}1$ protein expression (RR = 2.565, p=0.002) and lymph node metastases (RR=1.874, p=0.030) were also independent prognostic factors. Thus, TGF-${\beta}1$ protein expression may be correlated to oncogenesis and serve as an independent prognostic biomarker for NSCLC.

In order to improve trajectory tracking accuracy and disturbance-rejection performance of the ball and plate system, a zero steady-state error tracking control strategy based on the principle of internal mode was proposed, and the backstepping controller with a low-pass filter was designed to suppress the system’s internal disturbance. Firstly, a linear model of the ball and plate system is established and the common instability model for reference input and disturbance signals is derived. Secondly, the zero steady-state error tracking control strategy composed of three controllers which have respective function is proposed. Thirdly, the solving procedure of each controller is given and the stability of the closed-loop system is guaranteed by Lyapunov stability theory. Finally, simulation results show the presented control scheme has better dynamic performance and disturbance rejection ability, compared with other methods including H∞control, sliding mode control, and LQR control.

Senescence marker protein 30 (SMP30), a hepatocellular carcinoma (HCe) associated antigen had been identified by our research group. To study its mechanisms of regulation and associations with the occurrence and development of HCe, we inhibited expression by RNAi technique, and observed effects on the biological characteristics of Hep G2 cells. In cell viability assays, cell growth in the experimental group (with siRNA transfection) was elevated. In Transwell invasion assays, compared with blank and control groups, numbers of invading cells in the experimental group were significantly increased, whereas in apoptosis assays, the percentage apoptosis demonstrated no differences, but after UV irradiation, that in the experimental group was higher than the other two groups. In a word, SMP30 can inhibit the proliferation and invasion of human hepatoma cells and thus can be regarded as a cancer suppressive factor.

We adopt the PASTEL catalog combined with SIMBAD radial velocities as a testing standard to validate the stellar parameters (effective temperature $T_{eff}$, surface gravity log g, metallicity [Fe/H] and radial velocity $V_r$) from the first data release (DR1) of The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. After applying data reduction and temperature constraints to the sample obtained by cross-identification, we compare the stellar parameters from DR1 and PASTEL. The results show that the DR1 results are reliable under certain conditions. We derive a dispersion of 110 K, 0.19 dex, 0.11 dex and $4.91kms^{-1}$ in specified effective temperature ranges, for $T_{eff}$, log g, [Fe/H] and $V_r$ respectively. Systematic errors are negligible except for those of $V_r$. In addition, for stars with PASTEL [Fe/H] < -1:5, the metallicities in DR1 are systematically higher than those in PASTEL.

Background Baicalin has anti-infammatory, antibacterial, blood platelet aggregation-inhibiting, free oxygen radical-clearing, and endotoxin-decreasing properties. However, its molecular mechanism involved in the treatment of Adriamycin-induced nephrotic syndrome (NS) is still unclear. Objective This study aimed to explore the efects of baicalin on Adriamycin-induced nephrotic syndrome (NS) and to characterize the genes involved in this progression. Methods We established Adriamycin-induced NS model in 32 rats and used six rats in Sham group. Urinary total protein content and creatinine serum were assessed as physiological indicators. H&E staining was used to observe the pathological changes. We determined gene expression profles using transcriptome sequencing in the rat kidney tissues from Sham, Adriamycin, and Adriamycin+baicalin groups. KEGG was carried out to analyze the enriched pathways of diferentially expressed genes among these groups. Results Baicalin treatment relieved renal injury in NS rats. Expression of 363 genes was signifcantly diferent between the Adriamycin and Adriamycin+baicalin M groups. Most of the diferentially expressed genes were enriched in pathways involved in epithelial-mesenchymal transition (EMT), fbrosis, apoptosis, and infammation. Conclusions Overall, these data suggest that Adriamycin-induced NS can be attenuated by baicalin through the suppression of fbrosis-related genes and infammatory reactions. Baicalin is a potential drug candidate for the treatment of NS, and the identifed genes represent potential therapeutic targets.
