Objectives : The purpose of this paper is to study the origin, mechanism, category of Chest bind with static blood(血結胸), the relation to the syndrome of Heat entering the blood chamber(熱入血室證), and the comparison with Chest bind(結胸). Methods : Sikuquanshu(四庫全書), a comprehensive range of medical books, and Shanghanlun(傷寒論) annotation books were searched by 'Chest bind with static blood' keyword and analyzed. Results & Conclusions : 1. The syndrome of Chest bind with static blood is first brought up by ZhuGong(朱肱) and it can be derived from the syndrome of Heat entering the blood chamber or can be shown in upper middle lower energizer Stagnated Blood Syndrome(上中下焦蓄血證, SBC). Ever since the publication of Shanghanquanshengji(傷寒全生集), its category was expanded and prescriptions for the SBC were used. 2. In comparison, the cause of Chest bind with static blood is associated with blood heat(血熱), largely connected with blood, mental illness appeared, lesions are usually chest and sides, and the cause of Chest bind is associated with intermingled water heat (水熱) or phlegm heat(痰熱), not connected with blood, mental illness not appeared, lesions are from the beneath the heart to lower abdomen. 3. The syndrome of Chest bind with static blood derived from the syndrome of Heat entering the blood chamber can appear along side with the Liver Meridian associated with blood chamber or appear in chest, the syndrome appeared in upper energizer SBC can be shown in the chest due to gravity, the one appeared in middle energizer SBC can be shown in the chest due to the same level, the one appeared in lower energizer SBC can be shown in the chest due to the constitutional predisposition of YangQi(陽氣) uprise.

Objective: To evaluate the efficacy and safety of bevacizumab in the treatment of patients with metastatic colorectal cancer (mCRC). Methods: In a single-center, observational study of 91 Chinese patients with mCRC who received bevacizumab in combination with chemotherapy was conducted. Objective response rates (ORRs), progression-free survival (PFS), overall survival (OS) and adverse events were recorded, and the relationships between various clinical factors and PFS or OS were evaluated by Cox proportional hazards models. Results: Treatment with bevacizumab and chemotherapy was effective and tolerable. Univariate analysis showed that PFS and OS were significantly associated with the Eastern Cooperative Oncology Group performance status (ECOG-PS) score, duration of bevacizumab exposure, and whether chemotherapy was continued after discontinuation of bevacizumab treatment. A multivariate analysis showed that the duration of bevacizumab exposure and whether chemotherapy was continued after discontinuation of bevacizumab were independent prognostic factors for PFS and OS. Conclusion: In Chinese mCRC population, the shorter the duration of exposure to bevacizumab and chemotherapy, the worse the prognosis is.

Background: Soybean oil may protect against cancer of the breast and prostate. It may also exert beneficial influence in combination with other oils. Here, blends (20%, v/v) of sea buckthorn oil (SEBO), camellia oil (CAO), rice bran oil (RBO), sesame oil (SEO) and peanut oil (PEO) with soybean oil (SBO) were formulated. Materials and Methods: Oxidative stability (OS) and radical scavenging activity (RSA) of SBO and blends stored under oxidative conditions ($60^{\circ}C$) for 24 days were studied. By blending with different kinds oils, levels of polyunsaturated fatty acids (PUFA) decreased, while monounsaturated fatty acid (MUFA) content increased. Progression of oxidation was followed by measuring peroxide value (PV), p-anisidine (PAV), conjugated dienes (CD) and conjugated trienes (CT). Results: Inverse relationships were noted between PV and OS at termination of storage. Levels of CD and CT in SBO, and blends, increased with increase in time. The impact of SEO as additives on SBO oxidation was the strongest followed by RBO, CAO, SEBO and PNO. Conclusions: Oxidative stability of oil blends was better than SBO, most likely as a consequence of changes in fatty acids and tocopherols' profile, and minor bioactive lipids found in selected oils. The results suggest that these oil blends could contribute as sources of important antioxidant related to the prevention of chronic diseases associated to oxidative stress, such as in cancer and coronary artery disease.

Background: A number of association studies have been carried out to investigate the relationship between genetic polymorphisms in DNA repair genes and response to radiotherapy-based multimodality treatment of patients with rectal cancer. However, their conclusions were inconsistent. The objective of the present study was to assess the role of DNA repair gene genetic polymorphisms in predicting genetic biomarkers of the response in rectal cancer patients treated with neoadjuvant chemoradiation. Materials and Methods: Studies were retrieved by searching the PubMed database, Cochrane Library, Embase, and ISI Web of Knowledge. We conducted a meta-analysis to evaluate the association between genetic polymorphisms and the response in rectal cancer treated with neoadjuvant chemoradiation by checking odds ratios (ORs) and 95% confidence intervals (CIs). Results: Data were extracted from 5 clinical studies for this meta-analysis. The results showed that XRCC1 RS25487, XRCC1 RS179978, XRCC3 RS861539, ERCC1 RS11615 and ERCC2 RS13181 were not associated with the response in the radiotherapy-based multimodality treatment of patients with rectal cancer (p>0.05). Conclusions: This study shows that DNA repair gene common genetic polymorphisms are not significantly correlated with the radiotherapy-based multimodality treatment in rectal cancer patients.

The tubes in a heat exchanger, such as a steam generator (SG), are subjected to crossflow, and interaction between tubes and supports can happen, which can cause fretting wear of tubes. Although many experiments and models have been established, some detailed mechanisms are still not sufficiently clear. In this work, more attention is paid to obtain the regulation of impact and sliding in the complex process and many factors, such as excitation forces and clearances. The responses and contact forces were analyzed to obtain clear understanding of the influences of these factors. Room temperature tests in the air were established. The results show that the effect of clearance on the normal work rate is not monotonous and instead has two peaks. The force ratio can influence the normal work rate by changing the distribution of contact angles, which can result in higher sliding in the contact process. Fretting wear tests are conducted, and the wear surfaces are analyzed by a scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDX). The results of this work can serve as a reference for impactsliding contact analysis between AVBs and tubes in steam generators.

The objectives of this study were to determine the effect of herb formula HDDM, a modification of Huangdan decoction that has been shown to be effective in the treatment of glomerulonephritis and chronic renal failure, on the blood glucose levels in multiple low doses (MLD; 50 mg/kg for five consecutive days) of streptozotocin (STZ)-treated female B6C3F1 mice. Initial studies were performed to compare diabetes induction in five strains (e.g., B6C3F1, NOD, CD-1, C3H/HeN and C57BL/6) of mice by MLD-STZ, and immune changes following the treatment. The results suggested that the order of susceptibility to diabetes induction was NOD $\approx$ CD-1 > B6C3F1 $\approx$ C3H > C57BL/6. Furthermore, STZ modulation of T cell development, differentiation and activation might play a role in diabetes induction by MLD-STZ treatment. MLD-STZ-induced diabetes in female B6C3F1 mice was moderate, which allowed the evaluation of drug-induced protection or exacerbation of diabetes to be performed. As such, modulation of blood glucose by HDDM, which consisted of Da Huang (Radix Et Rhizoma Rhei), Huang Qi (Radix Astragali Seu Hedysari), Dan Shen (Radix Salviae Miltiorrhizae), Yin Yang Huo (Herba Epimedii), Yi Yi Ren (Semen Coicis or Coix lacryma-jobi), Mai Dong (Radix Ophiopogonis) and Shan Zhu Yu (Fructus Corni), was evaluated in MLD-STZ-treated female B6C3F1 mice. The results suggested that HDDM could lower the blood glucose levels, but it had no immunomodulatory activities. Additionally, HDDM-treated mice exhibited improved glucose tolerance. In conclusion, these studies have suggested that MLD-STZ-induced diabetes in female B6C3F1 mice is a useful model to evaluate drug modulation of diabetes, and that the herb formula HDDM possesses anti-diabetic effects.

Yoon Gil-Young(1911-1987) was a frontier of the field of Traditional Korean Medical Physiology(TKMP) who was academically active since mid 1950s until early 1970s. He wrote several important papers and books. Among his writings, "A Study on the Methodology of Traditional Korean Medical Physiology", which was published serially in the "Korean Oriental Medical Journal" from June 1966 until March 1967, played an important role in establishing the contemporary TKMP and showed his academic stance on Traditional Korean Medicine(TKM). This review will evaluate this paper's contribution to the establishment of TKMP in historical context, summarize the unique characteristics of his understanding of TKMP by analyzing the text, and then based on those information, examine his view on TKMP and TKM. Historically, this paper was written in transition period from the traditional TKM knowledge system to the modernized one. Aim of this paper was to provide a methodology for establishing TKMP as a scientific knowledge system like that of the western medicine. Based on his study of Yin-Yang theory and theory of five circuits and six qi in Huangdi's Internal Classics, he suggested those theories as methods to observing life phenomena and systematizing the observations. And he regarded these methods as of great value in determining the unique characteristics of TKM compared to those of western medicine. Through re-reading this paper, it was found that he had pride and confidence in the methodology of TKM, and also that he thought in scientizing and modernizing TKM it was very important to understand and efficiently put in use the methodology of TKM. It was also found that his view on TKMP and TKM was pro modernization.

Background: A moderate dose of radiation is the recommended treatment for solitary plasmacytoma (SP), but there is controversy over the role of surgery. Our study aimed at comparing different treatment modalities in the management of SP. Materials and Methods: Data from 38 consecutive patients with solitary plasmacytoma, including 16 with bone plasmacytoma and 22 with extramedullary plasmacytoma, were retrospectively reviewed. 15 patients received radiotherapy alone; 11 received surgery alone, and 12 received both. The median radiation dose was 50Gy. All operations were performed as radical resections. Local progression-free survival (LPFS), multiple myeloma-free survival (MMFS), progression-free survival (PFS) and overall survival (OS) were calculated and outcomes of different therapies were compared. Results: The median follow-up time was 55 months. 5-year LPFS, MMFS, PFS and OS were 87.0%, 80.9%, 69.8% and 87.4%, respectively. Univariate analysis revealed, compared with surgery alone, radiotherapy alone was associated with significantly higher 5-year LPFS (100% vs 69.3%, p=0.016), MMFS (100% vs 51.4%, p=0.006), PFS (100% vs 33.7%, p=0.0004) and OS (100% vs 70%, p=0.041). Conclusions: Radiotherapy alone can be considered as a more effective treatment for SP over surgery. Whether a combination of radiotherapy and surgery improves outcomes requires further study.

Although enhancer of zeste homolog 2 (EZH2) has been reported as an independent prognostic factor in renal cell carcinoma (RCC), little is known about the exact mechanism of EZH2 in promoting the genesis of RCC. However, several studies have shown that dysregulation of the Wnt/${\beta}$-catenin signaling pathway plays a crucial role. Therefore, we determined whether EZH2 could affect ACHN human RCC cell proliferation and invasion via the Wnt/${\beta}$-catenin pathway. In the present study, we investigated the effects of short interfering RNA (siRNA)-mediated EZH2 gene silencing on Wnt/${\beta}$-catenin signaling in ACHN cells. EZH2-siRNA markedly inhibited the proliferation and invasion capabilities of ACHN, while also reducing the expression of EZH2, Wnt3a and ${\beta}$-catenin. In contrast, cellular expression of GSK-$3{\beta}$ (glycogen synthase kinase-$3{\beta}$), an inhibitor of the Wnt/${\beta}$-catenin pathway, was conspicuously higher after transfection of EZH2 siRNA. These preliminary findings suggest EZH2 may promote proliferation and invasion of ACHN cells via action on the Wnt/${\beta}$-catenin signaling pathway.
