Abstract
As an important supplementary approach to randomized controlled trial, process evaluation(PE) aims to evaluate implementation of complex intervention and contextual factors associated with variation in outcomes, in order to explain the observed results in a comprehensive manner. However, PE has not been well applied in the clinical research of acupuncture. Based on existing literature, this paper summarized the main methodological frameworks of PE, as well as the status-quo of its application in acupuncture research. Meanwhile, it explored the research perspectives and implementation factors that were potentially relevant to PE in parallel with acupuncture trials. In addition, the paper put forward preliminary considerations on key contents corresponding to each step during the development of PE for acupuncture trials, in order to provide useful reference and innovative pathway for future studies that strive for comprehensive evaluation of acupuncture's effect.

Abstract
Atomic, electronic structure and composition of top-down metal-assisted wet-chemically etched silicon nanowires were studied by synchrotron radiation based X-ray absorption near edge structure technique. Local surrounding of the silicon and oxygen atoms in silicon nanowires array was studied on as-prepared nanostructured surfaces (atop part of nanowires) and their bulk part after, first time applied, in-situ mechanical removal atop part of the formed silicon nanowires. Silicon suboxides together with disturbed silicon dioxide were found in the composition of the formed arrays that affects the electronic structure of silicon nanowires. The results obtained by us convincingly testify to the homogeneity of the phase composition of the side walls of silicon nanowires and the electronic structure in the entire length of the nanowire. The controlled formation of the silicon nanowires array may lead to smart engineering of its atomic and electronic structure that influences the exploiting strategy of metal-assisted wet-chemically etched silicon nanowires as universal matrices for different applications.

Abstract
Barrett's esophagus (BE) is a premalignant condition associated with the development of esophageal adenocarcinoma (EAC). Despite the low risk of progression to EAC, evidence highlights the notably poor survival rates of this malignancy. The mainstay form of diagnosis of BE is endoscopy and biopsy sampling. However, research emphasizes limitations with regards to the histological detection of BE and associated dysplasia. The aim of this study is to evaluate the clinical significance of CEACAM6 as a potential biomarker for the diagnosis of BE and beyond. Retrospective tissue samples were obtained from columnar lined esophagus without goblet cells (n = 27), BE (n = 18), BE associated dysplasia (n = 16), and EAC (n = 24). Standardized immunohistochemistry for CEACAM6 was performed followed by quantitative staining analysis. Statistical analysis across the BE spectrum for CEACAM6 was undertaken and a P value <0.05 was considered significant. CEACAM6 expression increased from columnar lined epithelium (CLE) to BE with a subsequent decrease to dysplasia and adenocarcinoma. The expression of CEACAM6 was significant from CLE to BE at p 0.001, CLE to dysplasia at p 0.001, BE to dysplasia at p 0.006, CLE to adenocarcinoma at p 0.001 and BE to adenocarcinoma at p 0.001. There was no significant difference in expression between dysplasia and adenocarcinoma (P = 0.15). Our findings highlight the increasing expression of CEACAM6 from CLE to BE with a subsequent decrease to dysplasia and adenocarcinoma. In view of this, we advocate the utilization of this marker for the enhanced diagnosis of BE and for the distinction of BE and dysplasia.

Abstract
High-throughput, roll-to-roll growth and transferring of high-quality, large-area chemical vapor deposited (CVD) graphene directly onto a target substrate with a reusable metal catalyst is an enabling technology for flexible optoelectronics. We explore the direct transfer via hot lamination of CVD graphene onto a flexible substrate, followed by electrochemical delamination (bubble transfer) of the graphene. The transfer method investigated here does not require any intermediate transfer layer and allows the copper to be reused, which will reduce the production cost and avoid the generation of chemical waste. Such integration is one necessary step forward toward the economical and industrial scale production of graphene. Our method bares promise in various applications. As an example, we fabricated flexible solution-gated graphene field-effect-transistors, which exhibited transconductance as high as 200 μS.

Abstract
Two-photon fluorescence microscopy and confocal reflectance microscopy were compared to detect intracellular gold nanorods in rat basophilic leukaemia cells. The two-photon photoluminescence images of gold nanorods were acquired by an 800 nm fs laser with the power of milliwatts. The advantages of the obtained two-photon photoluminescence images are high spatial resolution and reduced background. However, a remarkable photothermal effect on cells was seen after 30 times continuous scanning of the femto-second laser, potentially affecting the subcellular localization pattern of the nanorods. In the case of confocal reflectance microscopy the images of gold nanorods can be obtained with the power of light source as low as microwatts, thus avoiding the photothermal effect, but the resolution of such images is reduced. We have noted that confocal reflectance images of cellular gold nanorods achieved with 50 microW 800 nm fs have a relatively poor resolution, whereas the 50 microW 488 nm CW laser can acquire reasonably satisfactory 3D reflectance images with improved resolution because of its shorter wavelength. Therefore, confocal reflectance microscopy may also be a suitable means to image intracellular gold nanorods with the advantage of reduced photothermal effect.

Abstract
A comparison was made of the cytokine transcripts in normal, monoclonal, MDS, and AML marrow aspirates. While both normal and monoclonal marrow aspirates contain transcripts for SCF, few MDS or AML marrow aspirates contain these transcripts. Similarly, IL1ra transcripts are found with reduced frequency in MDS and AML marrow aspirates. The fall in SCF transcripts between monoclonal and MDS marrow aspirates parallels the appearance of apoptosis and the reduced in vitro proliferative ability which are characteristics of MDS marrow aspirate cells. The frequent IL1beta production by MDS and AML marrow aspirate cells, with few marrow aspirates producing IL1ra transcripts, suggests that unbalanced IL1beta effects may contribute to the proliferative advantage of MDS and AML cells over their normal counterparts.

Abstract
To elucidate the role of the p53 tumor suppressor gene in prostate tumorigenesis, we probed for mutations in latent and clinical prostate cancers using single strand conformation polymorphism (SSCP) and restriction fragment length polymorphism (RFLP) analysis in combination with direct gene sequencing and immunohistochemical methodologies. Fifteen cases of subclinical and 32 cases of clinical carcinoma, the latter graded in stages A through D, were available for study. While p53 point mutations were detected in only 5 of 32 (16%) clinical cancers, no mutations were detected in latent disease. Of the carcinomas in stages B, C and D, 15% (2/13), 29% (2/7) and 9% (1/11) were positive for p53 mutations, respectively. Although no specific mutational patterns were observed, the aberrations found were predominantly single base missense substitutions. The data suggest not only an association of p53 mutation and progression of clinical prostate cancer, but also imply that some other mechanism(s) are at work in latent carcinoma.

Abstract
To evaluate the correlation between myosin heavy chain release and the necrosis mass, serum levels of myosin heavy chain fragments were determined serially in 55 patients with acute myocardial infarction. Eight of these patients were successfully treated with thrombolytic agents: the others were not treated. The same myosin titration was applied to the sera of 25 dogs with an experimental myocardial infarction. Six of the dogs were successfully treated with thrombolytic agents. The time courses of the myosin concentrations are typical and monophasic for all patients with a noncomplex myocardial infarction. The values for the kinetic parameters of myosin release are comparable to those previously reported. We have now determined that cumulative myosin release significantly correlates with cumulative creatine kinase (CK), CK-MB, and lactate dehydrogenase release, as well as with thallium-201 distribution, as determined for different patient groups. Thrombolytic treatment does not seem to qualitatively upset myosin kinetics. The results obtained in dogs with or without thrombolysis conclusively indicate that myosin release is a quantitative index of the necrosis mass. From a practical point of view, a few serial determinations of serum levels of myosin heavy chains are enough to estimate the necrosed mass in patients with acute myocardial infarction. More generally, serum myosin titration could be useful in detecting any cardiac disturbance involving myocardial injury resulting in membrane leakage of cardiac cells.
