Abstract
Induction of cell death and inhibition of cell survival are the main principles of cancer therapy. Resistance to chemotherapeutic agents is a major problem in oncology, which limits the effectiveness of anticancer drugs. A variety of factors contribute to drug resistance, including host factors, specific genetic or epigenetic alterations in the cancer cells and so on. Although various mechanisms by which cancer cells become resistant to anticancer drugs in the microenvironment have been well elucidated, how to circumvent this resistance to improve anticancer efficacy remains to be defined. Autophagy, an important homeostatic cellular recycling mechanism, is now emerging as a crucial player in response to metabolic and therapeutic stresses, which attempts to maintain/restore metabolic homeostasis through the catabolic lysis of excessive or unnecessary proteins and injured or aged organelles. Recently, several studies have shown that autophagy constitutes a potential target for cancer therapy and the induction of autophagy in response to therapeutics can be viewed as having a prodeath or a prosurvival role, which contributes to the anticancer efficacy of these drugs as well as drug resistance. Thus, understanding the novel function of autophagy may allow us to develop a promising therapeutic strategy to enhance the effects of chemotherapy and improve clinical outcomes in the treatment of cancer patients.

Abstract
Liver fatty acid-binding protein (L-FABP) and liver bile acid-binding protein (L-BABP), in the liver intra-cytoplasm of chicken, are members of the fatty acid-binding protein subfamily. This study was designed to analyze and compare L-FABP and L-BABP expression levels between fat and lean lines in chicken liver tissue, and to determine the relationship between their expression and lipid metabolism. Real-time polymerase chain reaction (PCR) and Western blotting were used to detect the mRNA and protein expression in liver tissue between the lean and fat lines. Real-time PCR showed that L-FABP mRNA expression in fat male chickens was higher than that in lean male chickens at 2, 3, 4, 5, 6, and 10 weeks of age (P < 0.05), and L-BABP mRNA expression in fat male chickens was higher than that in lean male chickens at 1, 2, 3, 4, 8, and 10 weeks of age (P < 0.05). Western blotting showed that the L-FABP protein expression in fat male chickens was higher than that in lean male chickens at 3, 5, 6, and 7 weeks of age (P < 0.05), and L-BABP protein expression in fat male chickens was higher than that in lean male chickens at 3, 4, 5, and 6 weeks of age (P < 0.05). These results suggested that chicken L-FABP and L-BABP affect abdominal fat deposition through differences in their expression level, and the possible mechanism is that a high expression level of L-FABP and L-BABP leads to a high lipogenesis rate and, ultimately, to lipid deposition.

Abstract
OBJECTIVE To investigate the roles of exogenous basic fibroblast growth factor (bFGF) on the repair of full-thickness articular cartilage defects in rabbits. DESIGN In the present study, a double-layered collagen membrane sandwiched with bFGF-loaded-nanoparticles between a dense layer and a loose layer was implanted into full-thickness articular cartilage defects in rabbits. By grafting the membrane in a different direction, the dense layer or the loose layer facing the surface of the subchondral bone, the effects of the released bFGF on the defects and the profiles of nine growth factors (GFs) in synovial fluid (SF) were investigated using histological methods and antibody arrays, respectively. RESULTS In the group with the loose layer facing the surface of the subchondral bone, fast release of bFGF was observed, and early high levels of endogenous transforming growth factor-β2 (TGF-β2), vascular endothelial growth factor (VEGF), bFGF, bone morphogenetic protein 2 (BMP-2), BMP-3, and BMP-4 in SF were detected by antibody arrays, especially on day 3. Chondrocyte-like cells were also observed in this group at an early stage. As a result, this group showed better levels of repair, as compared to the other groups in which low GF levels were detected at an early stage, and chondrocyte-like cells appeared much later. CONCLUSIONS Our study suggests that exogenous bFGF promotes articular cartilage repair by up-regulating the levels of multiple GFs, but administration at an early stage is required.

Abstract
OBJECTIVES To investigate the expression and clinical significance of the protein tyrosine phosphatase, nonreceptor type 11 (PTPN11 or SHP2) gene, which encodes Src homology 2 domain-containing phosphatase (SHP-2) in gastric cancer. METHODS SHP2 expression was detected by immunohistochemical staining and real-time quantitative reverse transcription-polymerase chain reaction in tissue samples of normal gastric mucosa and different grades of gastric cancer. Correlation between SHP2 expression and standard clinico pathological parameters was analysed. RESULTS Immunohistochemical staining revealed significantly higher rates of SHP2 expression in gastric cancer tissues (72.5%) versus normal gastric mucosa (21.9%). SHP-2 mRNA levels were also significantly higher in gastric cancer tissues versus normal gastric mucosa. SHP2 expression correlated significantly with tumour differentiation, clinical classification and lymph node metastases, but was independent of sex and age. CONCLUSIONS SHP-2 is upregulated in gastric cancer and may be related to the development of gastric cancer. SHP-2 may be a potential prognostic marker of, or a therapeutic target for, gastric cancer.

Abstract
OBJECTIVES Overexpression of hNUDC, a member of the nuclear distribution protein family, reduces cell population growth in prostate cancer cell lines, concurrent with induced morphological change and enhanced polyploidization. These phenomena are also closely associated with terminal phases of megakaryocyte maturation. MATERIALS AND METHODS In Dami cells, MTT and trypan blue assays were used to investigate cell viability and proliferation effects of hNUDC, and flow cytometry was used to analyse cell cycle and DNA content. Real-time RT-PCR was employed to detect mRNA expression. Activations of caspase-3, ERK, Akt and Stat-5 were determined by immunoblotting. May-Grünwald-Giemsa staining was performed to reveal cell morphology. RESULTS AND CONCLUSION Functional studies using adenovirus-mediated hNUDC overexpression led to inhibition of megakaryocyte proliferation via cell cycle arrest in G2/M transition phase. This process could have been be mediated by upregulation of p21 and downregulation of its downstream targets, including cyclin B1, cyclin B2 and c-myc. Enhanced apoptosis in turn ensued, characterized by increased caspase-3 activation, upregulation of pro-apoptotic Bax and downregulation of anti-apoptotic Bcl-2. Furthermore, hNUDC overexpression elevated the level of megakaryocyte maturation, associated with increased polyploidy, cell morphological changes and increased expression of cell surface differentiation markers, including CD10, CD44, CD41 and CD61. Our results further suggest that the ERK signalling pathway was involved in hNUDC overexpression-induced apoptosis. Taken together, this study provides experimental evidence for overexpression of hNUDC in Dami cells and suggests that activation of apoptotic machinery may be involved in megakaryocytic differentiation.

Abstract
OBJECTIVE Landiolol is an ultra-short-acting β-blocker that appears to be more cardioselective and less toxic than esmolol. The main objective of this study was to investigate the pharmacokinetics, pharmacodynamics, and safety of landiolol hydrochloride in healthy Chinese volunteers. METHODS We set 2-dose regimen (L and H groups) [L (low): 0.125 mg/kg/min (1 min) loading→0.02 mg/kg/min (20 min) continuous, H (high): 0.25 mg/kg/min (1 min) loading→0.04 mg/kg/min (20 min) continuous]. 20 healthy subjects of either sex were allocated randomly to the L and H groups (n=10, and 10). Blood samples were collected over 1 h after continuous infusion and were determined using a validated liquid chromatography/mass spectrometry (LC/MS/MS) assay. The safety of landiolol hydrochloride was assessed by adverse events recording, 12-lead ECG findings, physical examination, laboratory testing, and vital signs. RESULTS The main pharmacokinetic parameters of landiolol hydrochloride in healthy Chinese subjects were as follows: doses of 2 groups (L and H); Cmax of 400±110 and 731±246 ng/mL; C21min of 327±109 and 508±141 ng/mL; Tmax of 10.1±6.5 and 6.2±5.7 min; t1/2 of 4.7±1.6 and 6.5±1.7 min. Landiolol hydrochloride was safe. There were no adverse events in any subject. The heart rates and blood pressures of subjects administered landiolol hydrochloride decreased, but no clinically significant changes were observed. CONCLUSION The concentration of landiolol hydrochloride rapidly reached steady state levels, and rapidly dissipated after completion of administration. Landiolol hydrochloride appears to have rapid onset and short action.

Abstract
Motivated by an application to childhood obesity data in a clinical trial, this paper describes a multi-profile hidden Markov model (HMM) that uses several temporal chains of measures respectively related to psychosocial attributes, dietary intake, and energy expenditure behaviors of adolescents in a school setting. Using these psychological and behavioral profiles, the model delineates health states from the longitudinal data set. Furthermore, a two-level regression model that takes into account the clustering effects of students within school is used to assess the effects of school-based and community-based interventions and other risk factors on the transition between health states over time. The results from our study suggest that female students tend to decrease their physical activities despite a high level of anxiety about weight. The finding is consistent across intervention and control arms.
