In this report, we present 3 cases of malignant small bowel obstruction, treated with palliative care using endoscopic self-expandable metallic stent(SEMS) placement, with the aim to identify the safety and efficacy of this procedure. Baseline patient characteristics, procedure methods, procedure time, technical and clinical success rates, complications, and patient outcomes were obtained. All 3 patients had pancreatic cancer with small bowel strictures. One patient received the SEMS using colonoscopy, while the other 2 patients received SEMS placement via double balloon endoscopy using the through-the-overtube technique. The median procedure time was 104 min. The technical and clinical success rates were 100%. Post-treatment, obstructive symptoms in all patients improved, and a low-residue diet could be tolerated. All stents remained within the patients until their deaths. The median overall survival time(stent patency time) was 76 d. SEMS placement is safe and effective as a palliative treatment for malignant small bowel obstruction.

We demonstrate fast time-division color etectroholography using a multiple-graphics-processing-unit （GPU） cluster system with a spatial light modulator and a controller to switch the color of the reconstructing light. The controller comprises a universal serial bus module to drive the liquid crystal optical shutters. By using the controller, the computer-generated hologram （CGH） display node of the multiple-GPU cluster system synchronizes the display of the CGH with the color switching of the reconstructing light. Fast time-division color electroholography at 20 fps is realized for a three-dimensional object comprising 21,000 points per color when 13 GPUs are used in a multiple-GPU cluster system.

Transcatheter arterial chemoembolization(TACE) is widely accepted as a treatment for patients with hepatocellular carcinoma(HCC) in the intermediate stage according to the Barcelona Clinic Liver Cancer(BCLC) guidelines. Recently, balloon-occluded TACE(B-TACE) was developed in Japan. Despite the lack of a clear definition, B-TACE is generally defined as the infusion of emulsion of chemotherapeutic agents with lipiodol followed by gelatin particles under the occlusion of feeding arteries by a microballoon catheter, which leads to the dense lipiodol emulsion(LE) accumulation in HCC nodules. This phenomenon cannot be explained only by the prevention of proximal migration and leakage of embolization materials; it further involves causing local changes in the hemodynamics of the surrounding occlusion artery and targeted HCC nodules. Balloon-occluded arterial stump pressure plays an important role in the dense LE accumulation in targeted HCC nodules. Although randomized controlled trials comparing the therapeutic effect and the prognosis of B-TACE to those of the other TACE procedures, such as conventional-TACE and drug-eluting beads TACE, are still lacking, B-TACE is thought to be a promising treatment. The purpose of this review is to summarize the mechanism, therapeutic effect, indication, prognosis and complications of BTACE.

To provide quantitative feedback on surgical progress to ophthalmologists practicing inner limiting membrane(ILM)peeling,we developed an artificial eye module comprising a quartz crystal resonator(QCR)force sensor and a strain body that serves as a uniform force transmitter beneath a retinal *** a sufficiently large initial force must be loaded onto the QCR force sensor assembly to achieve stable contact with the strain body,the highly sensitive and wide dynamic-range property of this sensor enables the eye module to detect the slight forceps contact force.A parallel-plate strain body is used to achieve a uniform force sensitivity over the 4-mm-diameter ILM peeling *** these two components allowed for a measurable force range of 0.22 mN to 29.6 N with a sensitivity error within−11.3 to 4.2%over the ILM peeling *** this eye module,we measured the applied force during a simulation involving artificial ILM peeling by an untrained individual and compensated for the long-term drift of the obtained force data using a newly developed *** compensated force data clearly captured the characteristics of several types of motion sequences observed from video recordings of the eye bottom using an ophthalmological *** a result,we succeeded in extracting feature values that can be potentially related to trainee skill level,such as the mean and standard deviation of the pushing and peeling forces,corresponding,in the case of an untrained operator,to 122.6±95.2 and 20.4±13.2 mN,respectively.

The research on stem cell cultures has attracted much attention due to the recent development of regenerative medicine. Therefore, higher functionalities for devices used for culturing cells are strongly demanded. In this study, we fabricated cell culture sheets using transparent polyimide (PI), parylene (PA), and polyetheretherketone (PEEK) to make polymer materials that had microstructures. We then cultured stromal marrow cells (OP9) on them and investigated the cell alignment within the microstructures. Hot embossing was used to fabricate the microstructures with a width and depth of 5 μm on the polymer substrates. Cultivation of the cells was confirmed on the transparent PI and PA sheets, however, it was not observed on the PEEK sheet. Slight alignment of the cells was also observed along with the microstructures.

Background Estrogen receptor alpha （ER α） is the most important endocrine therapy responsiveness predictor for women with breast cancer. The accuracy of the prediction of the response to endocrine therapy was thought to be affected by involving the estrogen receptor coregulatory proteins and cross-talk between ER and other growth factor-signaling networks. Nuclear corepressor 1 （NCOR1） is one of the ER a transcription repressor. The objective of the study is to investigate the expression of NCOR1 at the protein level and pursue its predictive value for breast cancer endocrine therapy. Methods In the present study, the level of expression of NCOR1 protein has been assessed by immunohistochemistry in 104 cases of invasive carcinoma of the breast. Associations between NCOR1 protein expression and different clinicopathological factors and survival were sought. Results It was found that NCOR1 was expressed at significantly higher levels in responsive patients treated with endocrine therapy as first-line treatment on relapse. Responsive patients also had a significantly longer post-relapse survival and overall survival. No NCOR1 expression difference was found between patient by age, tumor size, lymph node status, different histological grade groups and human epidermal growth factor receptor 2 （HER2） status. Multivariate analysis showed that NCOR1 is an independent prognostic factor for over-all survival. Conclusions In breast cancer, NCOR1 protein expression level predicts response to endocrine therapy as first-line treatment for breast cancer patients on relapse and NCOR1 protein level assay may increase the accuracy in the endocrine treatment determination and, therefore, improving the patients survival.
