Esophageal cancer is one of the most high incidence of malignant tumors in China. However, the evaluation of chemoradiotherapy curative effect for esophageal cancer is lack of accurate and uniform criteria. In recent years, the imaging evaluation methods for chemoradiotherapy response in esophageal cancer have made some progress. The methods mainly include X-ray barium examination, endoscopic ultrasonography (EUS), computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography-computed tomography (PET-CT), and so on. Imaging examination has the advantages of safety, non-invasion and repeatability, and so on, which is a progressing tool for curative effect evaluation. Current status of the application of medical imaging which is used to evaluate esophageal cancer chemoradiotherapy curative effect were reviewed in this paper.

The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dŭ", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).

Objective To investigate the value of immunophenotypes in pathologic diagnosis of follicular lymphoma (FL) and the differential diagnosis between neoplastic follicle (NF) and reactive hyperplastic follicle (RHF).Methods 50 cases of FL and 10 cases of RHF as control were studied by clinical data, the expressions of CD20, bcl-2, CD3, CD10, bcl-6, CD21 and Ki-67 were detected by EnVision immunohistochemical method for the immunphenotypical pattern of FL and RHF.Results Among 50 FL cases , there were 24 male cases and 26 female cases, with median age of 50 years old (10-80 years old), including 32 cases (64 ％) involved predominantly neck lymph nodes.The histologic grades were 1-2 in 16 cases (32 ％) and ≥3 in 34 cases (68 ％).CD20, CD10 and bcl-6 were positive in NF tissues of FL, with irregular forms of NF and loss of the mantle area without clear demarcation, and infiltrating to NF, irregular shape and no clear perimeter.The bcl-2 was positive in all of grade 1-2 NF, and it was positive in 68 ％ (23/34) cases and was partial or total negative in 32 ％ (11/34) cases in grade≥3 NF.Those were poorly demarcated contours.The Ki-67 proliferative index of NF were ＜30 ％ in grade 1-2, and ＞30 ％ in grade ≥ 3, with the highest to 90 ％.In FL, the CD21 staining result showed follicular dendritic cells (FDC) network were synchronized with NF, and in some cases of grade ≥ 3, the FDC network were ruptured.In RHF, the CD20 was positive for round or oval nodules with clear demarcation.The CD10, bcl-6 and CD21 were positive and bcl-2 was negative in all germinal center without invasive immunophenotype.The Ki-67 index was high in germinal center, and sometimes polarity may be seen.Conclusion The immunophenotypical differences between FL and RHF include invasive characteristics, loss of follicular mantle area and germinal center pattern in the NF, while the normal follicular immunophenotype in the RHF.

Objective To observe the effect of oxymatrine(OM) on the expressions of p-STAT1 and PIAS1 signaling molecules at protein and mRNA levels in the proliferation of the human mesangial cells(HMC) induced by lipopolysaccharide(LPS) and explore the relationship between them.Methods HMCs were primarily cultured from a 4-month-old aborted human fetus(with informed consent and approved by the Ethics Committee of Lanzhou University),and then divided into 3 groups,that is,control group,LPS group(10 ng/ml) and OM group(LPS 10 ng/ml and OM 320 mg/L).After cultured for 12,24 and 48 h respectively,HMC proliferation were analyzed by methyl thiazolyl tetrazolium(MTT) assay and type Ⅳ collagen in the supernatants were detected by ELISA.At the same time points,the cells lysates were collected for the mRNA and protein expressions of p-STAT1 and PIAS1 by real-time quantitative RT-PCR and Western blot analysis.Results The cell proliferation of LPS group was faster and the type Ⅳ collagen protein was increased more than the control group(P

Objective To study the effect of oxymatrine on p-STAT3 and PIAS3 signaling molecule and it's mRNA expression in the proliferation of the human mesangial cells (HMCs) induced by lipopolysaccharide(LPS) and to explore their relationship. Methods HMCs were divided into three groups: control group, LPS group and oxymatrine group. HMC proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay. Type Ⅳ collagen in the supernatants of the cultured HMCs was detected by ELISA at 12, 24, 48 hours respectively. At the same time, the protein and mRNA expressions of p-STAT3 and PIAS3 were measured by Western blot and real-time quantitative RT-PCR. Results The cell proliferation, the mRNA and protein expression of type Ⅳ collagen, p-STAT3 in LPS group were increased compared with the control group (P<0.01), but they were decreased in oxymatrine group (P < 0.01). The expressions of protein and mRNA of PIAS3 in LPS group were decreased significantly compared with control group (P<0.01), but they were increased in oxymatrine group (P<0.01). Conclusion Oxymatrine can down-regulate the expression of p-STAT3 and up-regulate the expression of PIAS3, which plays an important role in the process of LPS-induced HMCs proliferation.

Objectives To determine the effects of Matrine (Ma) on signal transducers and activators of transcription (STAT) 1, 3, connective tissue growth factor (CTGF) and platelet -derived growth factor (PDGF) in glomerular mesangial cells (MC) induced by lipopolysaccharide (LPS), and to explore the protective mechanisms of Ma. Methods Ma were added to cultured glomerular mesangial cells which were exposed to LPS for 12, 24 and 48 hours. Real time polymerase chain reaction were used to determine STAT1, 3, CTGF, PDGF mRNA, The protein expression of STATI, 3 and p-STAT1, 3 were observed by Western blot. Results Compared with the control group, MC proliferation of the LPS group (10μg/ml) significantly increased, which were suppressed in the Ma (320 μg/ml) group (P < 0.01) at 12, 24, 48 hours. The expression of STAT1, 3, CTGF, PDGF mRNA and the levels of p-STAT1 , p-STAT3 protein was significantly increased in MC under LPS medium at 12, 24, 48 hours, which were obviously lower in Ma group than those of the LPS group, especially at 24, 48 hours. Conclusions The protective mechanisms of Matrine is considered to down-regulate the expression of STAT1, 3, CTGF and PDGF.
