Breast cancer metastasis is the most common cause of cancer-related death in women. Thus, seeking targets of breast tumor cells is an attractive goal towards improving clinical treatment. The present study showed that CCL18 from tumor-associated macrophages could promote breast cancer metastasis via PITPNM3. In addition, we found that pachymic acid (PA) could dose-dependently inhibit migration and invasion of MDA-MB-231cells, with or without rCCL18 stimulation. Furthermore, evidence was obtained that PA could suppress the phosphorylation of PITPNM3 and the combination of CCL18 and PITPNM3. Therefore, we speculate that PA could inhibit breast cancer metastasis via PITPNM3.

BACKGROUND/OBJECTIVES: This study aimed to investigate cancer-specific survival (CSS) and associated risk factors in elderly gastric cancer (EGC) patients. SUBJECTS/METHODS: EGC patients (≥ 70 yrs) who underwent curative gastrectomy between January 2013 and December 2017 at our hospital were included. Clinicopathologic characteristics and survival data were collected. Receiver operating characteristic (ROC) analysis was used to extract the best cutoff point for body mass index (BMI). A Cox proportional hazards model was used to determine the risk factors for CSS. RESULTS: In total, 290 EGC patients were included, with a median age of 74.7 yrs. The median follow-up time was 31 (1-77) mon. The postoperative 1-yr, 3-yr and 5-yr CSS rates were 93.7%, 75.9% and 65.1%, respectively. Univariate analysis revealed risk factors for CSS, including age (hazard ratio [HR] = 1.08; 95% confidence interval [CI], 1.01-1.15), intensive care unit (ICU) admission (HR = 1.73; 95% CI, 1.08-2.79), nutritional risk screening (NRS 2002) score ≥ 5 (HR = 2.33; 95% CI, 1.49-3.75), and preoperative prognostic nutrition index score < 45 (HR = 2.06; 95% CI, 1.27-3.33). The ROC curve showed that the best BMI cutoff value was 20.6 kg/m². Multivariate analysis indicated that a BMI ≤ 20.6 kg/m² (HR = 2.30; 95% CI, 1.36-3.87), ICU admission (HR = 1.97; 95% CI, 1.17-3.30) and TNM stage (stage II: HR = 5.56; 95% CI, 1.59-19.43; stage III: HR = 16.20; 95% CI, 4.99-52.59) were significantly associated with CSS. CONCLUSIONS: Low BMI (≤ 20.6 kg/m²), ICU admission and advanced pathological TNM stages (II and III) are independent risk factors for CSS in EGC patients after curative gastrectomy. Nutrition support, better perioperative management and early diagnosis would be helpful for better survival.

Autophagy has been suggested as a possible mechanism for non-apoptotic death despite evidence from many species that autophagy represents a survival strategy of cells under stress. From our previous findings that supranutritional doses of sodium selenite induced apoptosis in human leukemia cells, now we show autophagic cell death occurred after selenite exposure in HL60, suggested an alternative mechanism for the potential therapeutic properties of selenite. Additionally, Death-associated Protein Kinase (DAPK) performed a significantly increased expression during this process, concomitantly with gradually decreased phosphorylation at $Ser^{308}$. We further reveal that the up-regulation of DAPK which depends on selenite-activated ERK had no effect on autophagy. However, activation of DAPK via PP2A-mediated dephosphorylation at $Ser^{308}$ serves as a new strategy for autophagy induction. In conclusion, these results indicate that PP2A-mediated activated DAPK sensitizes HL60 cells to selenite, ultimately triggers autophagic cell death pathway to commit cell demise.

Purpose: To investigate the prognostic value of serum amyloid A (SAA) in patients with hepatocellular carcinoma (HCC) undergoing surgery. Materials and Methods: Preoperative serum samples of 328 patients with HCC who underwent curative resection and of 47 patients with benign liver lesion were assayed. Serum levels of SAA were measured by enzyme-linked immunosorbent assay and its correlations with clinicopathological characteristics and survival were explored. Results: Levels of SAA were significantly higher in patients with HCC than those with benign liver lesion. There were strong correlations between preoperative serum SAA level and tumor size and more advanced BCLC stage. On univariate analysis, elevated SAA was associated with reduced disease-free survival and overall survival (p=0.001 and 0.03, respectively). Multivariate analyses showed that serum SAA level was an independent prognostic factor for overall survival (hazard ratio 2.80, p=0.01). Conclusions: High SAA serum level is a novel biomarker for the prognosis of HCC patients.

Influenced by the western science and experimental medicine of recent times, Kampo medicine had been founded characterized by experiment at the Edo age in japan. However, the government of japan pursued the scientificalness of medicine blindly, then Kampo medicine completely westernized and moved towards the decline. In our modernization of Chinese medicine, the historical lesson of japan should be learned.

Chinese cabbage is a vegetable of Cruciferous family. It was usually consumed as Kimchi. It was known to have amount of vitamin c. Recently the trend for the development of functional food combined with oriental herbs. For this aim the study was performed to evaluate the hepatoprotective effect via antioxidant activity of leaf and root of Sanchon Chinese cabbage(Brassica campetris L.) comparatively. The methanol extracts of Chinese cabbage were tested for investigating the effects on the formation of lipid peroxide and the activities of free radical generating enzyme in vitro in bromobenzene-treated rats. The methanol extracts of chinese cabbage reduced bromobenzene-induced hepatic lipid peroxidation and inhibited the activity of xanthine oxidase. The methanol extracts of chinese cabbage did not activate amionopyrine N-demethylase, aniline hydroxylase and glutathione S-transferase. Epoxide hydrolase activity was decreased by bromobenzene, which was restored by pretreatment of the methanol extracts of chinese cabbage. The results suggest that the methanol extracts of Chinese cabbage is reduced by enhancing the activity of epoxide hydrolase.

The purpose of this study was to investigate the awareness, eating experience, and preference of kimchi, and the sensory evaluation of kimchi from Chinese and Korean students residing in Korea. General information (including age, sex, duration of staying, living status) was collected. A questionnaire was used to collect the information on awareness, eating experience, and preference of kimchi and dishes made with kimchi. Sensory evaluations were carried out on a 10 point scale. All subjects (37 Koreans, 43 Chinese) were aware of kimchi, with 98% of the Chinese subjects recognizing kimchi as a Korean traditional food and 65% having eaten kimchi at least once a day. The types of kimchi preferred by Chinese subjects were generally sweet and not over-bearing in seasoning, hotness, or ripeness. The more frequently eaten foods made with kimchi were jjigae, bokkeumbap, bibimbap and kimbap. However, the more preferred dishes made with kimchi were bossam, jeongol, bokkeum, jeon, and ramyeon. The Chinese subjects were especially sensitive to spicy odors ($4.6{\pm}2.2/10$), salted seafood odors ($4.6{\pm}2.3/10$), offodors ($4.4{\pm}2.3/10$) and aftertaste ($5.9{\pm}2.1/10$) compared to Korean subjects. Taken all together, the perception as well as sensory characteristic of kimchi needs to be improved for the globalization of kimchi.

Background: Prostate carcinoma is the second most common cancer among men worldwide. Developing new therapeutic approaches and diagnostic biomarkers for prostate cancer (PC) is a significant need. The Chinese herbal medicine Panax quinquefolius saponins (PQS) have been reported to show anti-tumor effects. We hypothesized that PQS exhibits anti-cancer activity in human PC cells and we aimed to search for novel biomarkers allowing early diagnosis of PC. Methods: We used the human PC cell line DU145 and the prostate epithelial cell line PNT2 to perform cell viability assays, flow cytometric analysis of the cell cycle, and FACS-based apoptosis assays. Microarray-based gene expression analysis was used to display specific gene expression patterns and to search for novel biomarkers. Western blot and quantitative real-time PCR were performed to demonstrate the expression levels of multiple cancer-related genes. Results: Our data showed that PQS inhibited the viability of DU145 cells and induced cell cycle arrest at the G1 phase. A significant decrease in DU145 cell invasion and migration were observed after 24 h treatment by PQS. PQS up-regulated the expression levels of p21, p53, TMEM79, ACOXL, ETV5, and SPINT1 while it down-regulated the expression levels of bcl2, STAT3, FANCD2, DRD2, and TMPRSS2. Conclusion: PQS promoted cells apoptosis and inhibited the proliferation of DU145 cells, which suggests that PQS may be effective for treating PC. TMEM79 and ACOXL were expressed significantly higher in PNT2 than in DU145 cells and could be novel biomarker candidates for PC diagnosis.

The aim of this study was to detail characteristics of mammary Paget's disease (PD) representing the whole population in China. A total of 4211 female breast cancer inpatients at seven tertiary hospitals from seven representative geographical regions of China were collected randomly during 1999 to 2008. Data for demography, risk factors, diagnostic imaging test, physical examination and pathologic characters were surveyed and biomarker status was tested by immunohistochemistry. The differences of demography and risk factors between PD with breast cancer and other lesions were compared using Chi-square test or t-test, with attention to physical examination and pathological characters. The percentage of PD was 1.6% (68/4211) in all breast cancers. The mean age at diagnosis was 48.1, and 63.2% (43/68) patients were premenopausal. There is no difference in demography and risk factors between PD with breast cancer and other breast cancer (P > 0.05). The main pattern of PD in physical exam and pathologic pattern were patients presenting with a palpable mass in breast (65/68, 95.6%) and PD with underlying invasive cancer (82.4%, 56/68) respectively. The rate of multifocal disease was 7.4% (5/68). PD with invasive breast cancer showed larger tumor size, more multifocal disease, lower ER and PR expression and higher HER2 overexpression than those in other invasive breast cancer (P < 0.05). These results suggested that PD in China is a concomitant disease of breast cancer, and that PD with underlying invasive cancer has more multiple foci and more aggressive behavior compared with other breast invasive cancer. We address the urgent needs for establishing diagnostic and therapeutic guidelines for mammary PD in China.

Background: Despite the growing acceptance of laparoscopic colon surgery, an abdominal incision is needed to remove the specimen and perform an anastomosis. Recently, natural orifice specimen extraction (NOSE) and intracorporeal anastomosis have been proposed to minimize abdominal wall trauma and improve the quality of laparoscopic colon resections Objective: To evaluate the feasibility and safety of a new approach combining intracorporeal delta-shaped anastomosis and transvaginal specimen extraction for totally laparoscopic sigmoid colectomy. Materials and Methods: Mobilization of bowel and dissection of lymph nodes were performed laparoscopically. After both proximal and distal incisal edges about 10.0 cm distance from sigmoid neoplasm were transected with an Endoscopic Linear Cutter-Straight, a small incision about 1.0 cm was created on the each colon wall of the contralateral side of the mesentery. Then anvils of an Endoscopic Linear Cutter-Straight were inserted into each colon through the small incisions, and incision and anastomosis between the walls of each colon were performed with a linear stapler. A V-shaped anastomosis was made on the wall and the remnant openings was reclosed with the Endoscopic Linear Cutter-Straight. The culdotomy was enlarged with laparoscopic ultrasound dissector. Transvaginal extraction of specimens was accomplished through a wound protector. Results: Surgery was performed for 11 patients with sigmoid cancer. No intraoperative complications or conversions occurred. The mean operating time was 132 min. All the patients were treated laparoscopically without any postoperative complications. Conclusions: The procedures of intracorporeal delta-shaped anastomosis and transvaginal specimen extraction are safe and oncologically acceptable for selected colon cancer cases.
