Objective To investigate the interrelationship between Golgi phosphoprotein 3 ( GOLPH3 ) expression with vasculoar endothelial growth factor( VEGF) expression in the progression of human gastric cancer by detecting the expression level of GOLPH3 and VEGF. Methods Immunohistochemistry ( IHC) was used to detect the ex-pression of GOLPH3 and VEGF in 55 cases of gastric cancerous and carcinoma-adjacent tissues. Pearson correlation analysis was used to discuss the association between GOLPH3 expression with VEGF expression. Results The im-munohistochemical detection showed that the positive expression rates of GOLPH3 and VEGF were 67. 27%, 58. 18% respectively, which were significantly higher than the positive expression rates in carcinoma-adjacent tis-sues ( P<0. 05 ) . A statistical analysis revealed that the positive expression rate of GOLPH3 and VEGF in the gas-tric cancer tissues were strongly correlated with depth of invasion ( P<0. 05 ) , distant metastasis ( P<0. 01 ) and TNM stages (P<0. 01), whereas it did not significantly correlate with age or gender or size of tumor. Compared with the negative for the GOLPH3 expression, the VEGF expression in gastric cancer tissues positive for the GOL-PH3 expression was significantly higher. The protein level of GOLPH3 expression was positively correlated with VEGF expression (r=0. 508,P<0. 01). Conclusion GOLPH3 overexpression may regulate gastric angiogenesis by upregulating the expression of VEGF, which affects the invasion and metastasis of gastric cancer.

OBJECTIVETo assess the exposure level of total N-nitroso compounds (TNOCs) in the residents of high- and low-risk areas for esophageal cancer in southern China.

METHODSSamples of duplicate plate diets and 12 hr overnight urine were collected from 120 male adults in each of the 2 areas, a high-risk area (Nanao county) and a low-risk area (Lufeng county) for esophageal cancer. The 240 male healthy subjects (35 - 64 years old) were selected by a 3-stage random cluster sampling procedure. Levels of TNOC, N-nitrosamino acids (NAAs) and volatile N-nitroso compounds (VNOC) in the samples were measured by Thermo Energy Analyzer.

RESULTSThe detectable rate (95%) of diet TNOC, daily dietary TNOC intake (4.25 +/- 0.84) micromol/day, 12-hr urinary TNOC excretion levels (1.76 +/- 0.23 ng/12 h) and daily dietary intake of VNOC (266 +/- 31.2 microg/day) in the high-risk area were all significantly higher than those of the low-risk area. Oesophageal cancer mortality rates were positively and significantly associated with daily dietary TNOC intake and 12-hr urinary TNOC excretion. Urinary NAAs excretion levels were not different in the two areas.

CONCLUSIONThe results suggest that TNOCs may be implicated in the etiology of esophageal cancer in southern China.

BACKGROUND:Tripterygium hypoglaucum(Levl.)Hutch (THH) has been accurately confirmed a good clinical therapeutic effect for rheumatoid arthritis(RA).However.functionaI mechanism of THH remains unclearly.OBJECTIVE:To investigate the effect of THH on proliferation and apoptosis of macrophage-like synoviocytes and fibroblast-like synoviocytes from patients with RA and to explore its dose-effect relation.DESIGN.TIME AND SETTING:In vitro cytology grouping controlled observation was performed in the Center Laboratory of the First Clinical College of Shantou University and the Laboratory for Cellular Biology of Southern MedicaI University from August 2003 to June 2007.MATERIALS:Synovium was obtained from 6 patients with RA and 3 normaI synovial samples.All samples sourced from patients admitted in Department of Orthopaedics.the First Clinical College of Shantou University and in Spinal and Joint Surgery of Nanfang Hospital.The water extracts of THH contained 0.667 g/mL crude drug.METHODS:Synovial cells were isolated by digesting synovial tissue with collagenase.CD68+and CD68-synoviocytes were sorted from synovial cells by Dynabeads(magnetic celI sorting)from the 2~(nd)-4~(th) passages of synoviocyes.After 72 hours incubation,all groups of isolated synoviocytes were cultured in culture medium containing the flnaI concentrations of 0 mL/L,5 mL/L,1 0 mL/L and 20 mL/L of THH for 24 and 48 hours,respectively,and the common culture medium was sewed as the control. MAIN OUTCOME MEASURES:The morphology of synoviocytes were observed by inverted phase contrast microscope and studied by scanning electron microscopy(SEM).In vitro cell growth was assessed by the MTT assay,and synoviocytes apoptosis was evaluated using temlinaI deoxynucleotidyl transferase biotin-dUTP nick end labeling(TUNEL)assay and a flow cytometry.RESULTS:CD68~+ synoviocytes were appeared macrophage-like and CD68~- synoviocytes were exhibited fibroblast-like.After incubated with THH,some synoviocytes presented the volume of cells deflated,progressively destruction of cell membrane,microvillus or pseudopodium tended to be decreased even disappeared,and apoptosis bodies appeared.When incubated with 2% THH,proliferation inhibiUon and inducing apoptosis could be observed;it showed that THH had the cytotoxic effect on synoviocytes.The effect of proliferation inhibition and inducing apoptosis on CD68-and CD68+synoviocytes from RA patients was more significantly than that from normal arthritis (P<0.01).When incubated with 1%THH.proliferation inhibition and inducing apoptosis on synoviocytes from RA patients also could be found(P<0.01),but not found on normal synoviocytes(P>0.05).Compared with the negative controI group.proliferation inhibition was no significant difference On all groups with the low dose (≤5 mL/L) of THH(P>0.05).Furthermore,the effect of proliferation inhibition and inducing apoptosis on synoviocytes decreased in a dose-dependent and time-dependent manner.The inhibition rate of synoviocytes also could be found positively correlated with apoptosis rate aftat treatment of THH(r=0.497,P<0.01).CONCLUSlON:THH have cytotoxic effect on rheumatoid synoviocytes and normal synoviocytes.it can inhibit macrophage-like synoviocytes and fibroblast-like synoviocytes from RA on proliferation and induce them to apoptosis.In the some contraction of THH.proliferation Inhibition and inducing apoptosis can be occur on synoviocytes from RA but not on normal synoviocytes.

Background Current researches of choroidal structure changes primarily focus on macular choroidal thickness in adolescents and children,but there are few studies on peripapillary choroidal thickness in children with enhanced depth imaging (EDI)-OCT.In addition,the reliability of manual measurements to peripapillary choroidal thickness is an important factor for the estimation of EDI-OCT.Objective This study was to determine the repeatability and reproducibility of manual measurements of peripapillary choroidal thickness in children by EDI-OCT.Methods A reliability evaluation of diagnosis test was performed.EDI-OCT technology was used to image the peripapillary choroidal thickness in 49 children aged 7-14 years in Eye Hospital of Wenzhou Medical University from February to March 2015 under the informed consent of their custodians.An annular scanning was carried out surrounding optical disc by the same ophthalmologist with Spectralis OCT,and the peripapillary choroidal thickness was manually measured at global,temporal,superotemporal,superonasal,nasal,inferonasal and inferotemporal zones.The intraclass and interclass repeatability and reducibility of measuring values from intraobserver,inter-observer and intra-session were evaluated with intraclass correlation coefficients (ICC),and BlandAltman agreement analysis was used to assess the consistency of repeated measurements.Results The average age in the subjects was (9.9 ± 1.3) years.No significant difference was found in the mean difference of reduplicative measured peripapillary choroidal thickness at each zone (all at P＞0.05).The ICCs of intra-observer,inter-observer and intra-session were 0.971-0.993,0.827-0.952 and 0.974-0.991,respectively,and the 95％ limit of agreement of global peripapillary choroidal thickness were-12.4-9.7 μm,-15.2-11.6 μm and-16.3-19.1 μm,respectively.Conclusions The repeatability,reproducibility and consistency are favorable in manually measured values of peripapillary choroidal thickness from EDI-OCT image.EDI-OCT appears a good application in the assessment of peripapillary choroidal thickness in children.

The effects of waveform and frequency on proliferation of human lung adenocarcinoma cell line A549 were studied by FX-4000 strain unit . The results showed that cellular proliferation index (PI) reduced significantly in squarewave group when compared with the control after A549 cells were subjected to collagen I 0-25% elongation at frequency 20 cycles/min, 40 cycles/min and 60 cycles/min for 2h. The PI showed no distinct difference in trianglewave group. The PI increased in heartwave group. These data indicate that A549 cells do respond to physiological strain in vitro. The effects of squarewave and 60 cycles/min tension may be optimal for inhibiting the proliferation of A549 cells. To select appropriate waveform and frequency will be of paramount importance to inhibiting proliferation of A549 cells.

Objective To evaluate the efficacy of accelerated partial breast irradiation ( APBI ) and whole breast irradiation ( WBI ) with simultaneous integrated boost ( SIB ) from the perspective of economics, and provide a reference for postoperative adjuvant therapy mode selection for early-stage breast cancer after breast-conserving surgery. Methods A total of 355 early-stage breast cancer patients who underwent APBI or WBI-SIB after breast-conserving surgery were evaluated on efficacy and cost-effectiveness, of which 177 patients received APBI, and 178 patients received WBI-SIB. Survival analysis was done according to treatment received. NCI-CTC 3.0 was used to score the toxicities. Breast aesthetic outcome were evaluated with Harris standards. Results Median follow-up was 42 months ( 5.8 -92.7 months) . The 3-year locoregional recurrence free survival( LRFS) rates in APBI group and WBI-SIB group were 98.2％ and 97.6％, distant metastasis free survival( DMFS) were 94.3％ and 93.7％, disease-free survival ( DFS) were 93.1％ and 91.6％, and overall survival 95.5％ and 94.3％, respectively, without statistically significant differences(P>0.05). Compared with WBI-SIB group, the acute reaction rates in APBI group decreased from 5. 6％ to 3.4％(χ2 =6.044, P <0. 05), and late reactions from 5.6％ to 2.3％ (χ2 =6.149, P<0. 05), while the cosmetic outcome improved from 88.8％ to 93.8％(χ2 =5.22, P<0. 05). Moreover, the processing average time was shortened by 26.5 d (χ2 =40.76, P<0. 05). Conclusions After breast-conserving surgery, the efficacy of APBI showed no difference from WBI-SIB with respect to 3-year local control, disease-free survival, and overall survival, but displayed a significantly better toxicity profile and cost-effectiveness ratio for early breast cancer patients. It can be used as a good radiotherapy model after breast-conserving surgery in early-stage breast cancer.

Objective We aimed to investigate the clinical values of combination of blood creatinine and cystatin C for acute kidney injury(AKI)diagnosi. Methods Total 7 627 patients were studied retrospectively. The AKI was classified by creatinine or cystatin C according to the Kidney Disease:Improving Global Outcomes criteria. Results The maximum levels of cystatin C and creatinine were correlated(Spearman′s rank coefficient 0.699,P < 0.001). The area under a receiver operating characteristic curve of maximum cystatin C value for pre-dicting in-hospital death was 0.761(95% confidence interval 0.693 ~ 0.828). Total 1 004 and 173 patients were classified into AKI by blood creatinine or by cystatin C(13.2% vs.2.3%,P<0.001),respectively.The total inci-dence of AKI was 14.7% diagnosed by the combination of the two markers.In multivariable logistic model,the cre-atinine negative plus cystatin C positive group was associated with a higher in-hospital death compared with the cre-atinine and cystatin C double negative group(OR 15.524,95% confidence interval 5.110 ~ 47.166,P < 0.001). Conclusion Combination of cystatin C increased sensitivity of creatinine for AKI diagnosis and facilitated to iden-tify in-hospital patients with high risk.
