  • Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

  • A theory of the school which attach great importance to moxibustion therapy was more developed from 'Ge Hong(葛洪)', 'Wang Tao(王燾)' up to "BianQueXinShu(扁鵲心書)" of 'Dou Cai(竇材)' in Song Dynasty. The first volume of "BianQueXinShu" was described about the principles of health preserving method, diagnosis, treatment related with meridian system, support Yang theory, moxibustion therapy over the 10 chapters and in the continued 3 chapters, explained the symptoms and related moxibustion therapies. The summary is as follows. The Yang energy is the essence of the human body and it is minutely explained in "Hwangdineijing(黃帝內經)". However, the younger scholars after 'Zhang Zhongjing(張仲景)' held different views with "Hwangdineijing" so they didn't control serious diseases. Supporting the Yang energy, it will be possible to human body in good health and long life and perennial youth and longevity. To do like this, the first important thing is a moxibustion, the second is a Taoist hermit medication(丹藥) and the third is well usage of Radix Aconiti Lateralis Preparata. According to the sequence of Yang energy deficiency, the stages of diseases are classified as Ordinary Gi(平氣), Latter deficient state(微虛), The more deficient state(甚虛), Exhausting state(將脫), Exhausted state(已脫) and in the consideration of each stage, it is used gradually with warm-natured berbs, warm-acrid herbs, warm-heated herbs and moxibustion therapy. If it comes to the stage of Exhausted state, the Yang energy is too weak to treat a disease. Therefore it is easy to harm human body with usage the treatment of the Purgationist school theory or the Cold and cool medical school theory, so it is needed a great attention to use these therapies. To summarized the keynote of 'Du Jae''s moxibustion therapy, the one is a minority of selection of points(1$^{\sim}$2 acupuncture points), the second is a majority of moxibustion units(50$^{\sim}$500 units), and the other is a focused selection of points on spleen and kidney(especially Gwanwon, CC4). And in this book, it was explained concretely about the size of moxibustion, according to the experiment with mentioned size, the burning time of moxibustion was almost 4 min 40 sec, so the big size moxibustion was one of the characteristic of moxibustion therapy revealed in this book. Also it was used 'Suseongsan(睡聖散)' - a kind of analgesic herb complexes - to reduce a pain during the usage of moxibustion therapy in this book. To develop the moxibustion theory, it is more investigated in the future that there wasn't significant relation between Gwanwon(CC4) and spleen and kidney meridian in theory, compared to many used Gwanwon(CC4) in the prescription, where as mentioned the importance of spleen and kidney in treatment, that considering the burning time(1 unit - 4 min 40 sec, 12 units an hour, maximum 288 units a day) there were no guidances about meals, sleeping, stool and urine, and that there was no concrete study about the toxicity of 'Suseongsan' as analgesic moxibustion therapy.

  • This paper presents an efficient method utilizing user-defined computer functional codes to determine the reliability of an embankment slope with spatially varying soil properties in real time. The soils' mechanical properties varied with the soil layers that had different degrees of compaction and moisture content levels. The Latin Hypercube Sampling (LHS) for the degree of compaction and Kriging simulation of moisture content variation were adopted and programmed to predict their spatial distributions, respectively, that were subsequently used to characterize the spatial distribution of the soil shear strengths. The shear strength parameters were then integrated into the Geostudio command file to determine the safety factor of the embankment slope. An explicit metamodal for the performance function, using the Kriging method, was established and coded to efficiently compute the failure probability of slope with varying moisture contents. Sensitivity analysis showed that the proposed method significantly reduced the computational time compared to Monte Carlo simulation. About 300 times LHS Geostudio computations were needed to optimize precision and efficiency in determining the failure probability. The results also revealed that an embankment slope is prone to high failure risk if the degree of compaction is low and the moisture content is high.

  • Pt-Co alloy nanowire array was directly synthesized by electrochemical deposition with polycarbonate template at -1.0V and subsequent chemical etching of the template. The use of Pt-Co alloy nanowire array-modified electrode (Pt-Co NAE) for the determination of morphine (MO) is described. The morphology of the Pt-Co alloy nanowire array has been investigated by scanning electron microscopy (SEM) and energy disperse X-ray spectroscopy (EDS) analysis), respectively. The resulting Pt-Co NAE offered a linear amperometric response for morphine ranging from $2.35\times10^{-5}$ to $2.39\times10^{-3}$ M with a detection limit of $7.83\times10^{-6}$ M at optimum conditions. This sensor displayed high sensitivity and long-term stability.

  • Five new lanthanide coordination polymers, $[Ln_2(1,4-NDC)_2(1,4-HNDC)_2(phen)_2]_n$ (Ln = Er (1), Yb (2)), and $[Ln_2(1,4-NDC)_3(phen)_2(H_2O)_2]_n$ (Ln = Nd (3), Gd (4), Er (5)) ($1,4-H_2NDC$ = 1,4-naphthalenedicarboxylic acid, phen = 1,10-phenanthroline), have been successfully prepared via the reaction of corresponding trivalent lanthanide salt, $1,4-H_2NDC$ and phen in the presence of NaOH and pyridine under hydrothermal condition. Pyridine plays a key role in the synthesis of these lanthanide coordination polymers. Single-crystal X-ray diffraction analyses indicate that compounds 1-5 all form a 2-D network while different salt anions result in the diversity of crystal structures. These lanthanide coordination polymers showed a considerable thermal stability in TGA analyses.

  • Background: S100A14 has recently been implicated in the progress of several types of cancers. This study aimed to investigate the clinical significance and possible mechanisms of action of S100A14 in the invasion and metastasis of hepatocellular carcinoma (HCC). Methods: S100A14 expression in HCC was detected at mRNA and protein levels and its prognostic significance was assessed. Functional roles of S100A14 in HCC were investigated using MTT, BrdU, wound healing, transwell invasion assay and HCC metastatic mouse model. Results: S100A14 was significantly elevated in HCC tissues, correlated with multiple tumor nodes, high Edmondson-Steiner grade and vascular invasion. Multivariate Cox analysis showed that the S100A14 expression level was a significant and independent prognostic factor for overall survival (OS) of HCC patients (hazard ratio=1.98, 95% confidence interval=1.14-3.46, P=0.013). S100A14 promoted cell proliferation, invasion and metastasis of HCC in vitro and in vivo. Conclusion: These results suggest S100A14 is a novel prognostic marker and therapeutic target for HCC.

  • This paper presents the structural health monitoring (SHM) of Shanghai Tower. In order to provide useful information for safety evaluation and regular maintenance under construction and in-service condition, a comprehensive structural health monitoring (SHM) system is installed in Shanghai Tower, which is composed of a main monitoring station and eleven substations. Structural responses at different construction stages are measured using this SHM system and presented in this study. Meanwhile, a detailed finite element model (FEM) is created and comparison of results between SHM and FEM is carried out. Results indicate that the time-dependent property of concrete creep is of great importance to structural response and the measured data can be used in FEM updating to obtain more accurate FEM models at different construction stages. Therefore, installation of structural health monitoring system in super-tall buildings could be considered as an effective way to assure structural safety during the construction process.

  • This paper presents the results of an experimental study on the structural performance of an innovative GFRP-concrete composite beam construction, which is reinforced with longitudinal GFRP pultruded box-profile and transverse steel stirrups. GFRP perfobond (PBL) shear connectors are employed to enhance the bonding performance between the GFRP profile and the concrete portion. To investigate the shear and flexural performance of this composite system, eight specimens were designed and tested under three-point and four-point bending. The main variables were the height of the composite beam and the shear span-to-depth ratio. The test results indicated that bonding cracks did not occur at the interface between the GFRP profile and the concrete until the final stage of the test. This shows that the specimens performed well as composite beams during the test and that the GFRP PBL connectors were reliable. Based on the test results, two calculation methods were used to determine the flexural and shear capacity of the composite beams. A comparative study of the test and theoretical results suggests that the proposed methods can reasonably predict both the flexural and shear capacities of the specimens, whereas the provisions of ACI 440 are relatively conservative on both counts.

  • OK-432, a Streptococcus-derived anticancer immunotherapeutic agent, has been applied in clinic for many years and achieved great progress in various cancers. In the present study, we investigated its anticancer effect on bladder cancer through tumor associated macrophages (TAMs). MTS assay validated OK-432 could inhibit proliferation in both T24 and EJ bladder cell lines. OK-432 also induced apoptosis of bladder cancer cells in vitro. Consequently, we demonstrated that OK-432 could suppress the bladder cancer cells migration and invasion by altering the EMT-related factors. Furthermore, using SD rat model, we revealed that OK-432 inhibited tumor growth, suppressed PCNA expression and inhibited metastasis in vivo. Taken together, these findings strongly suggest that OK-432 inhibits cell proliferation and metastasis through inducing macrophages to secret cytokines in bladder cancer.
