Purpose: To explore the value of systemic inflammatory markers as independent prognostic factors and the extent these markers improve prognostic classification for patients with inoperable advanced or metastatic gastric cancer (GC) receiving palliative chemotherapy. Methods: We studied the prognostic value of systemic inflammatory factors such as circulating white blood cell count and its components as well as that combined to form inflammation-based prognostic scores (Glasgow Prognostic Score (GPS), Neutrophil-Lymphocyte Ratio (NLR), Platelet Lymphocyte Ratio (PLR), Prognostic Index (PI) and Prognostic Nutritional Index (PNI)) in 384 patients with inoperable advanced or metastatic gastric cancer (GC) receiving first-line chemotherapy. Univariate and multivariate analyses were performed to examine the impact of inflammatory markers on overall survival (OS). Results: Univariate analysis revealed that an elevated white blood cell, neutrophil and/or platelet count, a decreased lymphocyte count, a low serum albumin concentration, and high CRP concentration, as well as elevated NLR/PLR, GPS, PI, PNI were significant predictors of shorter OS. Multivariate analysis demonstrated that only elevated neutrophil count (HR 3.696, p=0.003) and higher GPS (HR 1.621, p=0.01) were independent predictors of poor OS. Conclusion: This study demonstrated elevated pretreatment neutrophil count and high GPS to be independent predictors of shorter OS in inoperable advanced or metastatic GC patients treated with first-line chemotherapy. Upon validation of these data in independent studies, stratification of patients using these markers in future clinical trials is recommended.

Li, Li-Wei,Ji, Guang-Shi,Yang, Yan-Zhao,Ameer, Abdul Nasir,Kim, Min Sun,Park, Byung Rim,Jin, Yuan-Zhe The Korean Society of Pharmacology 2015 The Korean Journal of Physiology & Pharmacology Vol.19 No.3

Orthostatic hypotension is most common in elderly people, and its prevalence increases with age. Attenuation of the vestibulo-sympathetic reflex (VSR) is commonly associated with orthostatic hypotension. In this study, we investigated the role of glutamate on the vestibulo-solitary projection of the VSR pathway to clarify the pathophysiology of orthostatic hypotension. Blood pressure and expression of both pERK and c-Fos protein were evaluated in the nucleus tractus solitarius (NTS) after microinjection of glutamate into the medial vestibular nucleus (MVN) in conscious rats with sodium nitroprusside (SNP)-induced hypotension that received baroreceptor unloading via sinoaortic denervation (SAD). SNP-induced hypotension increased the expression of both pERK and c-Fos protein in the NTS, which was abolished by pretreatment with glutamate receptor antagonists (MK801 or CNQX) in the MVN. Microinjection of glutamate receptor agonists (NMDA or AMPA) into the MVN increased the expression of both pERK and c-Fos protein in the NTS without causing changes in blood pressure. These results indicate that both NMDA and AMPA receptors play a significant role in the vestibulo-solitary projection of the VSR pathway for maintaining blood pressure, and that glutamatergic transmission in this projection might play a key role in the pathophysiology of orthostatic hypotension.

Ji, Jun,Wang, He-Shuang,Gao, Yan-Yan,Sang, Li-Min,Zhang, Li Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.18

Kr$\ddot{u}$ppel-like factor 4 is a transcription factor which plays an important role in development and progression of various carcinomas. Curcumin characterized by excellent anti-cancer properties is regarded as a serviceable natural compound used in carcinoma therapy. This study aimed at exploring the impact of KLF4 overexpression in cooperation with curcumin on the proliferation, apoptosis and invasion of human gastric carcinoma BGC-823 cells. Flow cytometry analysis, CCK-8 assays, transwell assays and Western blot results showed that KLF4 overexpression combined with curcumin had significant anti-proliferation, pro-apoptosis and anti-invasion effects on BGC-823 cells. We also found that KLF4 had synergistic effects with curcumin, better promoting apoptosis and inhibiting proliferation and invasion of gastric carcinona cells. These results indicate that KLF4 could be used as a potential therapeutic target; curcumin could act as an auxiliary and provide a promising therapeutic strategy in stomach cancer.

Polyelectrolyte nanoparticles based thin-film nanocomposite (TFN) membranes for amino acids separation

Yan-Li Ji,Wei-Jie Qian,Quan-Fu An,Kueir-Rarn Lee,Cong-Jie Gao 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.66 No.-

We have designed a novel type of thin-film nanocomposite (TFN) membranes with embedded polyelectrolyte nanoparticles (PNPs) and investigated their applicability in the separation of amino acids. PNP particles were mixed with piperazine (PIP) and interfacial polymerized with trimesoyl chloride (TMC), allowing for simultaneous improvement in water permeability, amino acid selectivity, and anti-fouling property. Separation performance could be conveniently tuned by modulating the chemical structure of PNPs and their content in TFN membranes, as well as adjusting the feed pH value. This work would promote the application of polyelectrolyte nanoparticles based TFN membranes in the separation and purification of amino acids.

Excited states of 113In have been populated through the heavy-ion fusion evaporation reaction 110Pd(7Li, 4n)113In. A new band with the configuration of a proton d5/2 orbital is identified. Two ΔI = 2 intruder bands, built on the πh11/2 and the πg7/2 orbitals, have been extended to spins (63/2-)ħ and (55/2+)ħ, respectively. The negative-parity πh11/2 intruder band shows a smooth increase in aligned spin, which is attributed to a strong proton-neutron interaction. The properties of the positive-parity πg7/2 band are discussed based on tilted axis cranking model calculations, and the features of the antimagnetic rotation for this band are shown after backbend. Furthermore, the contributions of the two-shears-like mechanism, the neutron (gd)ν shell and the core rotation are investigated for the positive-parity πg7/2 band.

Purpose: This study evaluated the value of contrast-enhanced ultrasonography (CEUS) in the ultrasound-guided microwave ablation (MWA) treatment of symptomatic focal uterine adenomyosis.Methods: This retrospective study was conducted between March 2020 and January 2023, enrolling 52 patients with symptomatic focal uterine adenomyosis who had undergone MWA. All patients were examined with CEUS before and after MWA. The non-perfused volume (NPV) was compared between CEUS and dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) following ablation. Therapeutic efficacy and safety were evaluated at 3-, 6-, and 12-month follow-ups. Additionally, this study explored the correlations between pre-treatment CEUS features and a volume reduction ratio indicating sufficient ablation, defined as 50% or more at the 3-month follow-up.Results: No significant differences in NPV were noted between CEUS and DCE-MRI immediately after MWA and during follow-up (all P>0.05). At the 3-month follow-up, the median VRRs for the uterus and adenomyosis were 33.2% and 63.9%, respectively. Sufficient ablation was achieved in 69.2% (36/52) of adenomyosis cases, while partial ablation was observed in the remaining 30.8% (16/52). The identification of non-enhancing areas on pre-treatment CEUS was associated with sufficient ablation (P=0.016). At the 12-month follow-up, significant decreases were observed in both the uterine and adenomyosis volumes (all P<0.001). Dysmenorrhea and menorrhagia were significantly alleviated at 12 months, and no major complications were encountered.Conclusion: CEUS can be used to evaluate the ablation zone of focal adenomyosis that has been treated with MWA, similarly to DCE-MRI. The identification of non-enhancing areas on pretreatment CEUS indicates satisfactory treatment outcomes.

Objective: To assess the safety and effectiveness of thalidomide (produced by CHANGZHOU PHARMACEUTICAL FACTORY CO.LTD) combined with chemotherapy in treating patients with advanced colorectal cancer. Method: A consecutive cohort of pretreated patients with advanced colorectal cancer were treated with thalidomide combined with chemotherapy. And chemotherapy for patients with advanced colorectal cancer were administered according to the condition of patients. Thalidomide was orally administered at a dosage of 50mg/day to 150mg/day before sleeping for at least 14 days. After at least 14 days of treatment, safety and side effects were evaluated. Results: There were 12 female and 3 male patients with advanced cancer recruited into this study, including 9 patients with colon, 6 patients with rectal cancer. The median age of patients was 57(41-82) years. Partial response was observed in 2 patients (2/15), and stable disease in 3 patients(3/15). Incidences of Grade 1 to 2 myelosuppression was observed in 1/15 patients, and Grade 1 to 2 elevation of hepatic enzyme was recorded in 1/15 patients. Adverse effects on the gastrointestinal tract were documented in 1/15 patients, and were Grade 1. No Grade 3-4 toxicities were diagnosed. No treatment related death was found. Conclusions: Thalidomide combined with chemotherapy was safe and mildly effective in treating patients with advanced colorectal cancer. However, further study should be conducted to clarify the effectiveness of this combination.

Weight Loss Correlates with Macrophage Inhibitory Cytokine-1 Expression and Might Influence Outcome in Patients with Advanced Esophageal Squamous Cell Carcinoma

Lu, Zhi-Hao,Yang, Li,Yu, Jing-Wei,Lu, Ming,Li, Jian,Zhou, Jun,Wang, Xi-Cheng,Gong, Ji-Fang,Gao, Jing,Zhang, Xiao-Tian,Li, Jie,Li, Yan,Shen, Lin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

Background: Weight loss during chemotherapy has not been exclusively investigated. Macrophage inhibitory cytokine-1 (MIC-1) might play a role in its etiology. Here, we investigated the prognostic value of weight loss before chemotherapy and its relationship with MIC-1 concentration and its occurrence during chemotherapy in patients with advanced esophageal squamous cell carcinoma (ESCC). Materials and Methods: We analyzed 157 inoperable locally advanced or metastatic ESCC patients receiving first-line chemotherapy. Serum MIC-1 concentrations were assessed before chemotherapy. Patients were assigned into two groups according to their weight loss before or during chemotherapy:>5% weight loss group and ${\leq}5%$ weight loss group. Results: Patients with weight loss>5% before chemotherapy had shorter progression-free survival period (5.8 months vs. 8.7 months; p=0.027) and overall survival (10.8 months vs. 20.0 months; p=0.010). Patients with weight loss >5% during chemotherapy tended to have shorter progression-free survival (6.0 months vs. 8.1 months; p=0.062) and overall survival (8.6 months vs. 18.0 months; p=0.022), and if weight loss was reversed during chemotherapy, survival rates improved. Furthermore, serum MIC-1 concentration was closely related to weight loss before chemotherapy (p=0.001) Conclusions: Weight loss both before and during chemotherapy predicted poor outcome in advanced ESCC patients, and MIC-1 might be involved in the development of weight loss in such patients.

Li, Wei,Sun, Ya Nan,Yan, Xi Tao,Yang, Seo Young,Kim, Eun-Ji,Kang, Hee Kyoung,Kim, Young Ho American Chemical Society 2013 Journal of agricultural and food chemistry Vol.61 No.45

<P>Zanthoxylum schinifolium is an aromatic shrub, and its pericarp and leaves are widely used in culinary applications in East Asian countries. It has also long been used in traditional Oriental medicine for treating the common cold, stomach ache, diarrhea, and jaundice. In this study, we identified two new compounds, zanthoxyloside (<B>1</B>) and schinifolisatin A (<B>13</B>), along with 23 known coumarins (<B>2</B>–<B>12</B>) and lignans (<B>14</B>–<B>25</B>), from a methanol extract of the stems of Z. schinifolium. The chemical structures of the compounds were determined by mass, 1D-, and 2D NMR spectroscopy. The anticancer effects of the isolated compounds were examined in three human cancer cell lines. Compounds <B>10</B>–<B>12</B> significantly reduced the proliferation of HL-60 human acute promyelocytic leukemia cells with IC<SUB>50</SUB> values of 4.62–5.12 μM. Treatment of PC-3 prostate cancer cells and SNU-C5 colorectal cancer cells with compound <B>10</B> resulted in potent antiproliferative activity, with IC<SUB>50</SUB> values of 4.39 and 6.26 μM, respectively. Also, compounds <B>10</B>–<B>12</B> induced the apoptosis of three cancer cells. Furthermore, the induction of apoptosis was accompanied by down-regulation of p-ERK1/2 MAPK, p-AKT, and c-myc levels, in a time-dependent manner. These data suggested that compounds <B>10</B>–<B>12</B> from Z. schinifolium have potential in cancer treatment.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jafcau/2013/jafcau.2013.61.issue-45/jf403479c/production/images/medium/jf-2013-03479c_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jf403479c'>ACS Electronic Supporting Info</A></P>

Li, Jian-Cheng,Liu, Di,Yang, Yan,Wang, Xiao-Ying,Pan, Ding-Long,Qiu, Zi-Dan,Su, Ying,Pan, Jian-Ji Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.8

Objective: To separate/enrich tumor stem-like cells from the human esophageal carcinoma cell line OE-19 by using serum-free suspension culture and to identify their biological characteristics and radiation resistance. Methods: OE-19 cells were cultivated using adherent and suspension culture methods. The tumor stem-like phenotype of CD44 expression was detected using flow cytometry. We examined growth characteristics, cloning capacity in soft agar, and radiation resistance of 2 groups of cells. Results: Suspended cells in serum-free medium formed spheres that were enriched for CD44 expression. CD44 was expressed in 62.5% of suspended cells, but only in 11.7% of adherent cells. The suspended cells had greater capacity for proliferation and colony formation in soft agar than the adherent cells. When the suspended and adherent cells were irradiated at 5 Gy, 10 Gy, or 15 Gy, the proportion of CD44+ suspended cells strongly and weakly positive for CD44 was 77.8%, 66.5%, 57.5%; and 21.7%, 31.6%, 41.4%, respectively. In contrast, the proportion of CD44+ adherent cells strongly positive for CD44 was 18.9%, 14.%, and 9.95%, respectively. When the irradiation dose was increased to 30 Gy, the survival of the suspended and adherent cells was significantly reduced, and viable CD44+ cells were not detected. Conclusion: Suspended cell spheres generated from OE-19 esophageal carcinoma cells in serum-free stem medium are enriched in tumor stem-like cells. CD44 may be a marker for these cells.
