Abstract
The present study tested the hypotheses that i) transforming growth
factor beta 1 (TGF-β1) enhances differentiation of rat bone marrow mesenchymal stem
cells (MSCs) towards the cardiomyogenic phenotype and ii)
intramyocardial implantation of the TGF-β1-treated MSCs improves cardiac function in
heart failure rats. MSCs were treated with different concentrations of TGF-β1 for 72
h, and then morphological characteristics, surface antigens and mRNA expression of
several transcription factors were assessed. Intramyocardial implantation of these
TGF-β1-treated MSCs to infarcted heart was also investigated. MSCs were initially
spindle-shaped with irregular processes. On day 28 after TGF-β1 treatment, MSCs
showed fusiform shape, orientating parallel with one another, and were connected with
adjoining cells forming myotube-like structures. Immunofluorescence revealed the
expression of cardiomyocyte-specific proteins, α-sarcomeric actin and troponin T, in
these cells. The mRNA expression of GATA4 and
Nkx2.5 genes was slightly increased on day 7, enhanced on day 14
and decreased on day 28 while α-MHC gene was not expressed on day 7,
but expressed slightly on day 14 and enhanced on day 28. Transmission electron
microscopy showed that the induced cells had myofilaments, z line-like substances,
desmosomes, and gap junctions, in contrast with control cells. Furthermore,
intramyocardial implantation of TGF-β1-treated MSCs to infarcted heart reduced scar
area and increased the number of muscle cells. This structure regeneration was
concomitant with the improvement of cardiac function, evidenced by decreased left
ventricular end-diastolic pressure, increased left ventricular systolic pressure and
increased maximal positive pressure development rate. Taken together, these results
indicate that intramyocardial implantation of differentiated MSCs enhanced by TGF-β1
improved cardiac function in heart failure rats.

Abstract
Background Temporary unipedicle screw reduction with percutaneous kyphoplasty (TUSR-PKP) is a relatively new method for managing osteoporotic vertebral compression fractures (OVCFs). A clinical retrospective comparative study was conducted to verify whether TUSR-PKP was noninferior to simple PKP regarding the management of OVCFs. Methods A total of 38 consecutive patients who sustained OVCFs without neurological deficits and had undergone surgeries in our hospital from June 2012 to January 2014 were included in the study: 24 patients underwent simple PKP (control group) and the other 14 patients underwent TUSR-PKP (treatment group). All 38 patients were asked to participate in a long-term (>1 year) follow-up. Visual analog scale (VAS) pain scores and Oswestry Disability Index (ODI) were recorded, and the Cobb angles and the vertebral body heights were measured on the lateral radiographs before surgery and on day 1, as well as 1, 3, 6, and 12 months after surgery. Results The patients in the treatment group had better vertebral height gain and greater improvement on ODI compared with the control group (p < 0.05). The VAS scores of the two groups were similar at all points until the end of the 1‑year follow-up period. Two patients from the treatment group and 5 patients from the control group had cement leakage. In the control group, 3 patients suffered adjacent or nonadjacent vertebra fractures. Conclusion TUSR-PKP is a safe and effective surgical option for OVCFs. Compared with simple PKP, TUSR-PKP provided at least equal results for OVCFs. Moreover, during the postsurgery observations, TUSR-PKP showed potential advantages including vertebral height gain, ODI improvement, and fewer subsequent refractures.

Abstract
Cucurbitacin-I (Cu-I, also known as Elatericin B or JSI-124) is developed to inhibit constitutive and abnormal activation of STAT3 in many cancers, demonstrating a potent anticancer activity by targeting disruption of STAT3 function. Here, we for the first time systematically studied the underlying molecular mechanisms of Cu-I-induced gastric cancer cell death both in vitro and in vivo. In our study, we show that Cu-I markedly inhibits gastric cancer cell growth by inducing G2/M phase cell cycle arrest and apoptosis at low nanomolar concentrations via a STAT3-independent mechanism. Notably, Cu-I significantly decreases intracellular GSH/GSSG ratio by inhibiting NRF2 pathway to break cellular redox homeostasis, and subsequently induces the expression of GADD45α in a p53-independent manner, and activates JNK/p38 MAPK signaling. Interestingly, Cu-I-induced GADD45α and JNK/p38 MAPK signaling form a positive feedback loop and can be reciprocally regulated by each other. Therefore, the present study provides new insights into the mechanisms of antitumor effects of Cu-I, supporting Cu-I as an attractive therapeutic drug in gastric cancer by modulating the redox balance.

Abstract
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgical denervation. Controls included injections of untransfected MSCs or the vehicle only. Muscles were harvested and analyzed at 2, 4, and 24 weeks post-transplantation. Immunofluorescence confirmed MyoG overexpression in MTMs. The muscle wet weight ratio was significantly reduced at 2 weeks after MTM injection (67.17±6.79) compared with muscles injected with MSCs (58.83±5.31) or the vehicle (53.00±7.67; t=2.37, P=0.04 and t=3.39, P=0.007, respectively). The muscle fiber cross-sectional area was also larger at 2 weeks after MTM injection (2.63×10³±0.39×10³) compared with MSC injection (1.99×10³±0.58×10³) or the vehicle only (1.57×10³±0.47×10³; t=2.24, P=0.049 and t=4.22, P=0.002, respectively). At 4 and 24 weeks post-injection, the muscle mass and fiber cross-sectional area were similar across all three experimental groups. Immunohistochemistry showed that the MTM group had larger MyoG-positive fibers. The MTM group (3.18±1.13) also had higher expression of MyoG mRNA than other groups (1.41±0.65 and 1.03±0.19) at 2 weeks after injection (t=2.72, P=0.04). Transplanted MTMs delayed short-term atrophy of denervated muscles. This approach can be optimized as a novel stand-alone therapy or as a bridge to surgical re-innervation of damaged muscles.

Abstract
The developments of "off-the-shelf" cell-scaffold constructs received an increasing interest in tissue engineering and regenerative medicine. Although the direct cryopreservation of a single-cell suspension in the tube is a relative mature technology, the cryopreservation of cell-scaffold constructs remains a challenge. Nanotechnology shows tremendous potential for cryopreservation in regulating of freezing and thawing processes. For example, nanoparticles have been reported to modify the cryoprotective agent (CPA), adjust the process of cooling and warming cycles. In this review, we provide an overview of cryopreservation of cell-scaffold constructs firstly. The review further focuses on the effects of nanotechnology on cryopreservation of cell-scaffold constructs, including the nanostructure of scaffold, nanoparticles in cooling and warming process in cryopreservation. The perspectives on future challenges in this filed are also pointed out.

Abstract
With the help of a nanoscale trench, the composition and conductance distributions of single GeSi quantum dots (QDs) are obtained by conductive atomic force microscopy combined with selective chemical etching. However, the obtained composition and current distributions are unwonted and inconsistent on the QDs grown at 680 °C. With a series of confirmatory experiments, it is suggested that a thick oxide layer is formed and remains on the QDs' surface after etching. Though this selective chemical etching has already been widely applied to investigate the composition distribution of GeSi nanostructures, the oxidation problem has not been concerned yet. Our results indicate that the oxidation problem could not be ignored on highly GeSi mixed QDs. After removing the oxide layer, the composition and conductance distributions as well as their correlation are obtained. The results suggest that QDs' current distribution is mainly determined by the topographic shape, while the absolute current values are influenced by the Ge/Si contents.

Abstract
OBJECTIVES The purpose of the study is to investigate the roles of miR-448 in ovarian cancer. METHODS miR-448 and CXCL12 mRNA expression were examined using qRT-PCR. CXCL12 promoter activity was detected by luciferase activity system. Cell proliferation was assayed by MTT or colony formation. Migration and invasion was assayed by transwell chamber. RESULTS miR-448 expression was usually under-expressed in ovarian cancer tissues and cell lines compared with their normal ones. Ectopic expression of miR-448 inhibited cell proliferation, migration and invasion in ovarian cancer cells. Moreover, bioinformatic prediction suggested that CXCL12 was a target gene of miR-448. We also demonstrated that restored expression of CXCL12 dampened miR-448-mediated suppression of tumor progression, which suggests the important role of miR-448 in tumor progression. CONCLUSION Our data indicate that miR-448 functions as a tumor suppressor in ovarian cancer, which exerts its activity by suppressing the expression of CXCL12.

Abstract
This study aimed to investigate the effect and mechanism of trauma flap healing promoted by the Zhikang capsule after radical breast cancer surgery. The enrolled breast cancer patients were randomly divided into two groups: treatment and observation. The patients in the treatment group were treated with the Zhikang capsule in addition to the conventional dressing changes, while patients in the observation group underwent only the regular dressing changes. Serum samples of 98 breast cancer patients (with complete clinical data) who underwent modified radical mastectomy were collected and analyzed for expressions of transforming growth factor beta (TGF-β) and basic fibroblast growth factor (bFGF). The drainage fluid amount and tissue necrosis rate were found to be lower in the treatment group than in the observation group. Moreover, bFGF expression in peripheral blood was higher in the treatment group than in the observation group. However, no significant difference was found between the two groups in the expression of TGF-β in peripheral blood. In conclusion, Zhikang capsule is effective in promoting flap healing after radical breast cancer surgery, and the increase of bFGF expression in peripheral blood may be the underlying mechanism.

Abstract
Retinoblastoma is a commonly seen and dangerous intraocular malignant tumor in infants. Studies have found that Claudin-1 and MMP-2, whose expressions may be connected, play roles in tissues of retinoblastoma. In this study we analyze and discuss changes of Claudin-1 and MMP-2 expressions, and the correlation between the expressions and retinoblastoma histological differentiation and optic nerve invasion. MaxVisionTM was applied to detect expressions of Claudin-1 and MMP-2 in 45 samples of retinoblastoma and 15 paraffin-embedded samples of normal retina. The correlation between Claudin-1 expression and MMP-2 expression was analyzed based on chi-squared test and Spearmans correlation test. Positive expressions of Claudin-1 in retinoblastoma were fewer than those in retina; higher positive expressions were found in differentiated tissues than in undifferentiated tissues; while compared to expressions in invasive optic nerves, Claudin-1 expressed more positively in optic nerves without invasion. As for MMP-2, its expressions were higher in retinoblastoma than in normal retina; undifferentiated tissues had higher positive expressions than differentiated tissues, which were not statistically significant; higher positive expressions were detected in invasive optic nerves. Thus, it could be concluded that the correlation between Claudin-1 expression and MMP-2 expression in retinoblastoma was negative. Expressions of Claudin-1 were positively related to histological differentiation and optic nerve invasion of retinoblastoma; while MMp-2 expression had negative correlation with histological differentiation and optic nerve invasion of retinoblastoma. Claudin-1 and MMP-2 played a negative role in the optic nerve invasion and tumor development of retinoblastoma.

Abstract
The study aimed to describe the prevalence of sarcopenia and discussed the applicability of different diagnostic criteria in Chinese older adults. 286 Chinese adults (136 men and 150 women) aged 60-88 were recruited. The prevalence of sarcopenia were calculated using different diagnostic criteria. Physical functioning was compared in sarcopenic and non-sarcopenic older adults. Compared with the standard of EWGSOP (European Working Group on Sarcopenia in Older People), the prevalence of sarcopenia was higher when the IWGS (International Working Group on Sarcopenia) standard was applied (Men: 7.4% vs. 0.8%; Women: 4.7% vs. 0%). If the AWGS (Aisa Working Group on Sarcopenia) standard was applied, the prevalence was 5.9% in men and 0.7% in women. In conclusion, the prevalence of sarcopenia in Chinese older adults ranged from 0% to around 10% when the diagnostic criteria of IGWS, EWGSOP and AGWS were applied. Further studies are still needed to investigate appropriate diagnostic criterion of sarcopenia for Chinese population.

Abstract
Monodisperse Pt nanoparticles (NPs) studded in a three-dimensional (3D) graphene nanobox are successfully synthesized through a simple in-situ confined growth route for the first time. The nano-zeolite A was used as a 3D substrate for in-situ growth of tri-layered graphenes on the crystal-surfaces, meanwhile, the inner micropores of which can also be utilized for the confined growth of Pt nanoparticles. The graphene sheets are curved on the edges to form a 3D hollow box morphology, where the monodisperse Pt nanoparticles are homogeneously studded on the inner surfaces. Moreover, the Pt content can be regulated from ∼8 to 50 wt%, and the particle size can be tuned from 2-5 nm by varying the pristine Pt-ion loading amount and CVD temperature. The Pt NP@graphene nanoboxes possess not only large pore volumes to effectively accommodate large amounts of oxygen, but also supply excellent electrical conductivity for the fast transfer of electrons (∼3.96 e(-)), resulting in a high efficiency (175 mA/mg Pt) and long-term stability (above 1000 cycles) for the oxygen reduction reaction.

Abstract
Here we report a novel interface tension-induced shrinkage approach to realize the synthesis of monodispersed asymmetrical mesoporous carbon nanohemispheres. We demonstrate that the products exhibit very uniform hemispherical morphology (130 × 60 nm) and are full of ordered mesopores, endowing them high surface areas and uniform pore sizes. These monodispersed mesoporous carbon hemispheres display excellent dispersibility in water for a long period without any aggregation. Moreover, a brand new feature of the mesoporous carbon materials has been observed for the first time: these monodispersed mesoporous carbon hemispheres show excellent thermal generation property under a NIR irradiation.
