Gastric cancer is the first in morbidity and mortality among cancers in China. The presence of peritoneal dissemination is the most common cause of recurrence after radical surgery, and has become a pivotal to the curative resection. Whether intraperitoneal chemotherapy can prevent peritoneal dissemination,lymph node metastasis, eradicate invisible seeding tumor cells, reduce peritoneal metastasis, improve survival and quality of life is always under investigation. This review focus on the theory, clinical applications and problems of intraperitoneal chemotherapy for gastric cancer.

AIM To study the reversal effect of erythromycin on multidrug resistance of human liver cancer cells BEL 7402. METHODS Cultivated the parental cells BEL 7402 in the presence of doxorubicin to obtain a multidrug resistant subline designated BEL 7402/ADM. The expression of P glycopro tein in BEL 7402 and BEL 7402/ADM cells was determined by using cell ELASA method. The cytotoxicity of drugs was determined by using MTT assay, and the intracellular concentration of doxorubicin in BEL 7402/ADM was determined using a spectrofluorometer. RESULTS After growing BEL 7402 cells in the presence of ADM for some time, the resulting cells (BEL 7402/ADM) became not only resistant to ADM but cross resistant to VCR and MMC, the P gp on the subline cells' surface was highly expresssed. Erythromycin, which is a lipophilic antibiotic, enhanced the anti tumor functions of ADM, VCR and MMC to BEL 7402/ADM cells and increased the intracellular concentration of ADM with no effect on the expression of the P gp in BEL 7402/ADM cells. CONCLUSUON Erythromycin can significantly reverse the multidrug resistance in BEL 7402/ADM cells, it may do so by saturating the P gp pathway to reduce the efflux of intracellular concentration of the drugs.

Objective To compare bispectral index (BIS) with narcotrend index (NI) during propofol-remifentanil anesthesia administered by target-controlled infusion (TCI).Methods Ten ASA Ⅰ or Ⅱ pafients aged 18-56 yr weighing 52-67kg undergoing abdominal surgery lasting>1h were included in this study.BIS and NI were monitored simultaneously.Anesthesia was induced with TCI of propofol with target plasma concentration (Cp) of 3～4μg/ml and remifentanil (Cp 3-4ng/ml).Tracheal intubation was facilitated with cis-atracurium 0.3 mg/kg.The patients were mechanically ventilated.PETCO2 was maintained between 30-35 mm Hg.Anesthesia was maintained with TCI of propofol and remifentanil by the anesthesiologist bhnded to BIS and NI values.according to hemedynamic parameters.BIS and narcotrend values were recorded every minute and compared by another anesthesiologist.All data were compared by Bland-Altman analysis and with Kappa coefficient for agreement.The correlation between BIS and NI was tested by Spearman correlation analysis.The number of error ofjudgement (Type Ⅰ was defined as BIS<40 and NI>62;Type Ⅱ was defined as BIS>60 and NI<20)Was counted.Results The correlation and agreement between BIS and NI during maintenance of propofol-remifentanil anesthesia administered by TCI showed good consistency.Conclusion Both NI and BIS Can help anesthesiologist control the depth of anesthesia during TCI of propofol-remifentanil.

Objective To explore the effect of transcription factor SOX18 on proliferation, migration and invasion of HeLa cells and its related mechanism. Methods HeLa cells were divided into blank control group, negative control group, pCI-SOX18 group. The expression of SOX18 and matrix metalloproteinase 7 (MMP-7) was detected by Western blot. The cell proliferation of different group was measured by MTT analysis. The effect of transcription factor SOX18 on migration and invasion of HeLa cells were measured by Transwell assay. Results HeLa cells were successfully transfected with pCI-SOX18. According to the results of MTT analysis, the cell number of pCI-SOX18 group showed no significant difference compared with blank control group and negative control group (P> 0.05). Compared to blank control group (0.23 ±0.05) and negative control group (0.28±0.07), SOX18 expression in pCI-SOX18 group (1.16±0.13) was significantly higher (F=218.14, P<0.05). Meanwhile, MMP-7 expression in pCI-SOX18 group (0.95±0.09) was increased significantly compared with blank control group (0.71±0.07) and negative control group (0.68±0.06) (F=116.84, P < 0.05). The number of cell migration in pCI-SOX18 group (175.71 ±17.17) was increased significantly compared with that in negative control group (95.19 ±8.18) and that in blank control group (93.34±9.72) (t=75.47, t=77.35, P<0.05). Compared with that in negative control group (98.63±14.62) and that in blank control group (96.57 ±13.95), the number of cell invasion in pCI-SOX18 group (247.12 ±36.82) was significantly higher (t=98.02, t=99.34, P<0.05). Conclusion Overexpression of SOX18 has no effect on the proliferation of HeLa cells, but has a significant role in promoting cell migration and invasion probably by regulating MMP-7 expression positively.
