Golgi phosphoprotein 3 (GOLPH3 )is closely related to the development and prognosis of cancer,such as non-small cell lung cancer,breast cancer,gastric cancer,esophageal cancer,colorectal cancer,etc.The mainly tumor pathogenisis related GOLPH3 includes modulating the response to DNA damage, vesicle trafficking,mTOR signaling pathway,mitochondrial functions,cytokinesis and Golgi vesicular malignant secretion,and then promoting cell proliferation,invasion and metastasis.GOLPH3 is expected to be a new tar-get for cancer therapy,which may become an important biomarker for the diagnosis,treatment and prognosis of cancer.

OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.

METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.

RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).

CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

With the deepening of modernization of traditional Chinese medicine (TCM), the method of quantification and standardization of TCM (i.e., quantitative characterization of TCM) has been more and more widely accepted by researchers. Chemometrics processes complicated data of TCM through applied mathematics, statistics and com-puter technology. And multivariable study was introduced into the quantitative characterization of TCM with great achievements. This article reviewed existed problems of quantitative characterization in TCM, the principles, char-acteristics, limitations, commonly used statistical methods and application conditions on quantitative characteriza-tion of TCM. With this review, a reference for further study of quantitative characterization of TCM was provided and a further research idea of combination with main methods of chemometrics was given.

Objective To analyze the prognostic factors and evaluate the effect of stereotactic radiosurgery for patients with multiple brain metastases. Methods Comparison was made in 53 such patients treated by stereotactic radiosurgery plus radiotherapy and 53 treated by radiotherapy alone. Patients were matched paired according to the following criteria: age, Karnofsky performance scale(KPS) before treatment, extent of systemic cancer and number of brain metastasis.Fourty patients had stereotactic radiosurgery, 13 patients stereotactic fractionated radiosurgery. In the stereotactic radiosurgery group, the patients were given a mean marginal dose of 20?Gy. Methods of stereotactic fractionated radiosurgery was 4 12?Gy per fraction, twice a week to a total dose of 15 30?Gy. Whole brain radiotherapy was given immediately after stereotactic radiosurgery. For patients treated by radiotherapy alone, the entire brain was treated by 30 40?Gy in 3 4 weeks. Results The median survival was 11.6 months in stereotactic radiosurgery plus radiotherapy and 6.7 months in radiotherapy alone. The one year survival rate and one year local control rate were 44.3%,17.1% and 50.9%,13.2%. Those with KPS increased after treatment gave 1 year survivals of 69.8% and 30.2%, respectively. The validity rates in CT or MRI three months after treatment were 82.0% and 55.0%.The difference in the two groups was found to be statistically significant (P

Objective To describe the characteristic MR findings in the brain in patients with amyotrophic lateral sclerosis (ALS), and to assess the diagnostic value of conventional MR imaging and fractional anisotropy (FA) of diffusion tensor imaging (DTI). Methods Conventional MR imaging was performed in 14 clinically proved ALS patients and 12 age-matched normal controls. Contrast enhanced MR images were acquired in 2 patients. Axial and coronal DTI scans were performed in 10 patients and 12 normal controls with SE-EPI sequence. The b value was 1 000 s/mm 2, the number of diffusion sensitive gradient direction was 25. For quantitative assessment of the corticospinal tract (CST), FA value of bilateral CST was measured at the level of posterior limb (PL) of the internal capsule (IC) and the cerebral peduncle of the midbrain, respectively, and statistical analysis was performed. Results Focal slight low signal intensity on T 1WI and high signal intensity (hyperintense to gray matter) on T 2WI was demonstrated in 6 ALS cases (42.9%) in bilateral PL of the IC, and the high signal was longitudinally continuous from the PL to the cerebral peduncle on T 2WI coronal plane, corresponding to the course of CST. In another 8 ALS cases (57.1%), the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was revealed in bilateral PL of the IC. No abnormal contrast enhancement was detected in the 2 cases. In control group, the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was demonstrated in all 12 subjects in bilateral PL of the IC. FA values of the patient group were significantly lower than that of the control group at the level of the PL of the IC (F=7.38, P

Objective To observe the expression of Na+/I- symporter(NIS) in cultured lactating mammary cells with different levels of iodine and the effect of tumor necrosis factor-α(TNF-α). Methods Original generation of mouse lactating mammary cells cultured in vitro were divided into low iodine group Ⅰ (LI-Ⅰ), low iodine group Ⅱ (LI-Ⅱ), adequate iodine group(AI), high iodine group Ⅰ(HI-Ⅰ), and high iodine group Ⅱ(HI-Ⅱ). Cells were cultured in DEME/F12 culture medium for 24 h with different concentrations of iodine (0,5,50,3000 and 10 000 μg/L, respectively), and TNF-α( 10-2 mg/L) was added to some of cultured cells for 24 h. The expression of NIS mRNA of lactating mammary cells was determined by real-time quantitative PCR and the expression of NIS protein was detected by In-Cell Western. Results In iodine alone group, the expression of NIS mRNA in LI-Ⅰ group [ (64.66 ± 14.99) x 10-4] was higher than that of AI group[ (22.76 ± 7.36) × 10-4, P ＜ 0.01 ]; HI-I group[ (10.18 ±3.53) × 10-4] and HI-Ⅱ group[ (8.59 ± 2.89) × 10-4] were lower than that of AI group(all P ＜ .0.05); With increased iodine concentration, the expression of NIS mRNA decreased. The expression of NIS mRNA in LI-Ⅰ group [(2.72 ± 0.45) × 10-4], LI-Ⅱ group[ (2.69 ± 0.68) × 10-4] and AI group[(1.80 ± 0.67) × 10-4] with iodine plus TNF-o were all lower than that of LI-Ⅰ group, LI-Ⅱ group[ (29.82 ± 4.47 ) × 10-4], and AI group without TNF-α (all P ＜ 0.01). In iodine plus TNF-α, the expression of NIS mRNA in HI-Ⅰ group[(6.58 ± 2.87) × 10-4] and HI-Ⅱ[(7.04 ± 1.36) × 10-4] group were all higher than that of AI group(all P ＜ 0.05); With increased iodine deficiency or iodine excess, the expression of NIS mRNA increased. With increased iodine concentration, the expression of NIS protein decreased in iodine alone group. The expression of NIS protein in iodine plus TNF-α was all lower than that in iodine alone group. In iodine plus TNF-α, the expression of NIS protein increased in both iodine deficiency and iodine excess conditions. Conclusions Iodine may decrease the expression of NIS mRNA and protein of lactating mammary cells. The expression of NIS mRNA and protein of lactating mammary cells was inhibited by TNF-α under different levels of iodine.
