OBJECTIVETo explore the effect of Jianpi Tongluo Jiedu Recipe (JTJR) on protein expression levels of COX-2, NF-kappaBp65, Bcl-2, and Bax, mRNA expression levels of COX-2 and Bcl-2, and the apoptotic index (Al) in gastric mucosa of patients with precancerous lesions of gastric cancer (PL-GC).

METHODSTotally 65 PLGC patients were recruited and treated by JTJR (modified by syndrome typing), one dose per day for six successive months. Protein expression levels of COX-2, NF-KBp65, Bcl-2, and Bax were detected in 65 patients using immunohistochemical (IHC) assay before and after treatment. mRNA expression levels of COX-2 and Bcl-2 were detected in 54 patients using reverse transcription-polymerase chain reaction (RT-PCR). Meanwhile, changes of Al was detected in 65 patients using TdT-mediated dUTP-biotin nick end labeling (TUNEL) fluorescence method.

RESULTSAfter treatment with JTJR, positive protein expression levels of COX-2, NF-KBp65, and Bcl-2 were obviously decreased in the gastric mucosa of PLGC patients (P <0.01), but Bax positive protein expression was found to be higher (P < 0.05). At the same time mRNA expression levels of COX-2 and Bcl-2 were significantly lower after treatment than before treatment (P < 0.05, P < 0.01); Al also increased after treatment (P < 0.05).

CONCLUSIONJTJR could promote apoptosis possibly via NF-kappaBp65/COX-2, COX-2/Bcl-2, and NF-kappaBp65/Bcl-2 signaling pathways, thereby affecting PLGC patients.

Objective:To investigate the inhibitory effect of Shenqi Fuzheng injection on the expression of VEGF gene in human hepatocellular carcinoma cell line MHCC97L,and to elucidate the effect of Shenqi Fuzheng injection on tumor invasiveness,and to validate it through siRNA technology.Methods:After 24 hours of addition of Shenqi Fuzheng Injection (MHC) in the culture system of MHCC97L,Real-time PCR and Western-blot were used to detect the expression of MMP-9 and MMP-9 in the control group (Shenqi Fuzheng),negative control group (NaCI) And the expression of VEGF and RNA in the blank control group,and to determine the effect of Shenqi Fuzheng injection on the expression of VEGF and RNA.The effect of Shenqi Fuzheng Injection on the invasiveness of MHCC97L cells was detected by Transwell assay.The lentiviral vectors of MHCC97L cells were transfected into 293T cells and transfected into MHCC97L cells.The transfected cells were transfected into 293T cells by Lipofectamine 2000,and transfected into MHCC97L cells.The Effect of Shenqi Fuzheng Injection on the Invasion of VEGFi Tumor by Transwell.Results:Shenqi Fuzheng injection could significantly decrease the expression of VEGF mRNA and protein in normal MHCC97L cells (P＜0.05),and decrease the invasiveness of tumor cells (P＜0.05).VEGF RNA interference was successful.After intervention,Shenqi Fuzheng injection could not decrease the invasiveness of MHCC97L tumor (P＞0.05).Conclusion:Shenqi Fuzheng injection can reduce the invasion of MHCC97L cells by inhibiting the expression of VEGF gene.
