National cancer registration reports provide a huge potential for identifying patterns and trends of important policy, research, prevention and treatment significance. As summary reports written on an annual basis, the China Cancer Registry Annual Reports (CCRARs) fall short from fully addressing their potential. This paper attempts to explore part of the patterns and trends hidden behind published CCRARs. It extracted data for cancer incidence rates (IRs) and mortality rates (MRs) for 2004, 2006 and 2009 from relevant CCRARs and portrayed 4 kinds of indicators in line graphs. The study showed that: a) all of the line graphs of age-specific IRs and MRs characterized typical "growth curves or histogram"; b) graphs of IRs and MRs for males and urban areas had higher peaks than that for females and rural regions; c) most of the line graphs of IR/MR ratios comprised a starting peak, a secondary peak and a decreasing tail and the secondary peaks for females and urban areas were higher than those for males and rural areas; d) most of the urban versus rural IR ratios valued above one, but most the urban versus rural MR ratios, below one; e) the accumulative IRs and MRs showed a stable increasing trend from 2004 to 2009 for urban areas, but mixed for rural regions.

Background: Hairy and enhancer of split 1 (Hes-1) protein is a downstream target of Notch signaling and is a basic helix-loop-helix transcriptional repressor. However, definitive evidence for a role in hepatocellular carcinoma (HCC) cells has not been reported. Here, Hes-1 was revealed to an important component of the Notch signaling cascade in HCC cell lines possessing different potential for lung metastasis. Materials and Methods: RNAi mediated by plasmid constructs was used to analyze the role of Hes-1 in MHCC-97L HCC cells by assessing proliferation, apoptosis, cell migration and matrigel invasion following transfection. Hes-1 protein expression analysis in HCC tissue was also conducted by immunohistochemistry. Results: Our studies revealed that Hes-1 was decreased in HCC cell lines with higher lung metastasis potential at both the mRNA and protein levels. Down-regulation of the Hes-1 gene in MHCC-97L cells resulted in increased cell proliferation, reduced apoptosis and increased migration and invasion. Conclusions: Hes-1 has potential prognostic value in post-surgical HCC patients and may be an independent prognostic indicator for overall survival and tumor recurrence. These findings have important implications for understanding the mechanisms by which Hes-1 participates in tumor proliferation and invasion.

XIAO JING MA,RUI ZHANG,YONG TAO SHEN,XIAO HUI QIU,YAN LIAN YANG,CHEN WANG 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2008 NANO Vol.3 No.2
We review the progress in observation of electrically induced conformational changes of a range of single molecules and molecular assemblies using scanning tunneling microscopy (STM). Recent results using species with optical active functional groups and supramolecular structures confirmed the previously observed effects that the cholesterol molecules with soft linkers have the conformational bistability when switching the bias polarity, while no discernable changes were observed for the mesogen molecules, containing rigid linking units. In addition, it was also observed that the linker units could have appreciable impacts on the assembling characteristics.

Fiber-reinforced polymer (FRP) composites are considered suitable candidates for structural materials of spacecrafts due to their excellent properties of high strength, light weight, and corrosion resistance. An online health monitoring method for FRP composites must be applied to space structures. However, the application of existing health monitoring methods to space structures is limited due to the harsh space environment. Here, carbon fiber-reinforced polymer (CFRP) composites embedded with fiber Bragg grating (FBG) sensors were prepared to explore the feasibility of strain monitoring using embedded FBG sensors in g-radiation environment. The analysis of the influence of radiation on the strain monitoring demonstrated that the embedded FBG can be successfully applied to the health monitoring of FRP composites in radiation environment.

Aristoyunnolin H is a novel aristophyllenesesquiterpenoid isolated from the traditional Chinese medicineAristolochia yunnanensis Franch. The presentresearch was designed to explore the anti-fibrotic effects ofaristoyunnolin H in adult rat cardiac fibroblasts (CFs)stimulated with angiotensin II (Ang II). Western blotanalysis data showed that aristoyunnolin H reduced theupregulation of fibronectin (FN), connective tissue growthfactor and collagen I(Col I) production induced by Ang II inCFs. By studying the dynamic intracellular changes ofCa2?, we further found that while aristoyunnolin H relievedthe calcium influx, it has no effect on intracellular calciumstore release. Meanwhile, aristoyunnolin H also inhibitedthe Ang II-stimulated phosphorylation of Ca2?/calmodulindependentprotein kinase II. In conclusion, aristoyunnolin Hmay attenuate extracellular matrix secretion in vitro byinhibiting Ang II-induced calcium signaling.

Cancer is a global public health issue that becomes the second primary cause of death globally. Considering the side effects of radio- or chemo-therapy, natural phytochemicals are promising alternatives for therapeutic interventions to alleviate the side effects and complications. Ginsenoside Rh2 (GRh2) is the main phytochemical extracted from Panax ginseng C.A. Meyer with anticancer activity. GRh2 could induce apoptosis and autophagy of cancer cells and inhibit proliferation, metastasis, invasion, and angiogenesis in vitro and in vivo. In addition, GRh2 could be used as an adjuvant to chemotherapeutics to enhance the anticancer effect and reverse the adverse effects. Here we summarized the understanding of the molecular mechanisms underlying the anticancer effects of GRh2 and proposed future directions to promote the development and application of GRh2.

Panax ginseng Meyer is a traditional Chinese medicine that is widely used as tonic in Asia. The mainpharmacologically active components of ginseng are the dammarane-type ginsenosides, which havebeen shown to have anti-cancer, anti-inflammatory, immunoregulatory, neuroprotective, and metabolicregulatory activities. Moreover, some of ginsenosides (eg, Rh2 and Rg3) have been developed intonutraceuticals. However, the utilization of ginsenosides in clinic is restrictive due to poor permeability incells and low bioavailability in human body. Obviously, the dammarane skeleton and glycosyls of ginsenosidesare responsible for these limitations. Therefore, improving the oral bioavailability of ginsenosideshas become a pressing issue. Here, based on the structures of ginsenosides, we summarized theunderstanding of the factors affecting the oral bioavailability of ginsenosides, introduced the methods toenhance the oral bioavailability and proposed the future perspectives on improving the oral bioavailabilityof ginsenosides.

Esophageal squamous cell carcinoma (ESCC) is one of the most life- and health-threatening malignant diseases worldwide, especially in China. Long noncoding RNAs (lncRNAs) have emerged as important regulators of tumorigenesis and tumor progression. However, the roles and mechanisms of lncRNAs in ESCC require further exploration. Here, in combination with a small interfering RNA (siRNA) library targeting specific lncRNAs, we performed MTS and Transwell assays to screen functional lncRNAs that were overexpressed in ESCC. TMPO-AS1 expression was significantly upregulated in ESCC tumor samples, with higher TMPOAS1 expression positively correlated with shorter overall survival times. In vitro and in vivo functional experiments revealed that TMPO-AS1 promotes the proliferation and metastasis of ESCC cells. Mechanistically, TMPO-AS1 bound to fused in sarcoma (FUS) and recruited p300 to the TMPO promoter, forming biomolecular condensates in situ to activate TMPO transcription in cis by increasing the acetylation of histone H3 lysine 27 (H3K27ac). Targeting TMPO-AS1 led to impaired ESCC tumor growth in a patient-derived xenograft (PDX) model. We found that TMPO-AS1 is required for cell proliferation and metastasis in ESCC by promoting the expression of TMPO, and both TMPO-AS1 and TMPO might be potential biomarkers and therapeutic targets in ESCC.
