In this study, Actin, 18S rRNA, PAL, GAPDH and CPR of Artemisia annua were selected as candidate reference genes, and their gene-specific primers for real-time PCR were designed, then geNorm, NormFinder, BestKeeper, Delta CT and RefFinder were used to evaluate their expression stability in the leaves of A. annua under treatment of different concentrations of Cd, with the purpose of finding a reliable reference gene to ensure the reliability of gene-expression analysis. The results showed that there were some significant differences among the candidate reference genes under different treatments and the order of expression stability of candidate reference gene was Actin > 18S rRNA > PAL > GAPDH > CPR. These results suggested that Actin, 18S rRNA and PAL could be used as ideal reference genes of gene expression analysis in A. annua and multiple internal control genes were adopted for results calibration. In addition, differences in expression stability of candidate reference genes in the leaves of A. annua under the same concentrations of Cd were observed, which suggested that the screening of candidate reference genes was needed even under the same treatment. To our best knowledge, this study for the first time provided the ideal reference genes under Cd treatment in the leaves of A. annua and offered reference for the gene expression analysis of A. annua under other conditions.

Objective To investigate the protective effect of modified Qianjin Weijing Decoction(MQJWJD)on TNF-α and NF-κB in rats with lung injury induced by particulate matter; To discuss relevant mechanism of action. Methods A tracheal drip 15 mg/kg fine particles of saline solution was used to establish modeling, every other day, three times. Thirty-two Wistar rats were randomly divided into normal group, model group and MQJWJD high-dose and low-dose groups, with eight rats in each group. Medication groups were given relevant medicine for gavage. The level of TNF-α in bronchoalveolar lavage fluid (BALF) was measured by ELISA. The expression of NF-κB protein in lung tissues was measured by immunohistochemistry. The histopathology of the lung injury was observed by light microscope. Results Compared with normal group, the level of TNF-α and the expression of NF-κB protein in the model group were higher than those in the normal group (P<0.01). Compared with model group, the level of TNF-α and the expression of NF-κB protein in MQJWJD low-dose and high-dose groups were lower than those in the model group (P<0.05, P<0.01). Pathological observation showed that, compared with normal group, model group showed intratracheal, alveolar and interstitial bacteria within a large number of fine particles calm, alveolar and pulmonary interstitial visible large amounts of phagocytic fine particles of macrophages and accompanied by more neutrophils and lymphocyte infiltration; Lung tissue pathological changes were significantly lighter in MQJWJD high-dose and low-dose groups than the model group. MQJWJD high-dose group showed mild inflammation, alveolar and pulmonary interstitial visible phagocytic fine particles of macrophages, a small amount of neutrophils and lymphocyte infiltration. Conclusion MQJWJD can reduce the pulmonary injury in rats induced by particulate matter and has protective effects on the rat model through decreasing the levels of TNF-α and the expressions of NF-κB protein in injured lung tissues.

OBJECTIVEChinese jianpi herbal recipe Weichangan (WCA) could increase the survival rate of advanced gastric cancer. This study was designed to investigate the molecular mechanism of WCA in treatment of gastric cancer by cDNA array, real-time quantitative PCR and immunohistochemical technique.
METHODA human gastric adenocarcinoma cell line SGC-7901 grafted onto nude mouse was used as the animal model. The mice were divided into 3 groups, one control and the two representing experimental conditions. Animals in the two experimental groups received either WCA over a 34-day period or 5-fluorouracil (5-FU) over 6-day period starting at 8th day after grafting. Control animals received saline on an identical schedule. Animals were killed 41 days after being grafted. To assess the effect of therapy tumor weight was determined by a electron balance immediately after the animals killed. SP immunohistochemical method was used to detect the expression of proliferating cell nuclear antigen (PCNA) in xenografts. For detection of apoptotic cells, apoptotic indices (AI) were examined by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate fluorescence nick end labeling (TUNEL) method. SP method was also used to detect the expression of cleaved Caspase-3. The expression profiles in paired WCA treated gastric cancer samples and the N. S. control samples were studied by using a cDNA array representing 14, 181 cDNA clusters. The alterations in gene expression levels were confirmed by real-time quantitative PCR. SP method was used to detect the expression of Phospho-Stat3 (Tyr705) and bcl-2.
RESULTWhen compared with controls, tumor growth was significantly inhibited by treatment with the WCA or 5-FU (P < 0.01, respectively). The average of tumor inhibitory rate in WCA group was (44.32 +/- 5.67)% and 5-FU (47.04 +/- 11.33)%. The average labeling index (LI) for PCNA in WCA group and 5-FU group was significantly decreased compared with the control group respectively. AI of human gastric cancer xenografts in nude mice was significantly increased to (9.72 +/- 4.51)% using TUNEL method in WCA group compared with the controls (2.45 +/- 1.37)%. 5-FU group was also found a significantly increased AI compared with the controls. The expression of cleaved Caspase-3 in WCA group and 5-FU group was significantly increased compared with the control group respectively. There were 45 different expression ESTs among the control sample pool and WCA sample pool. There were 24 ESTs up-regulated in WCA samples and 21 ESTs down-regulated. These 45 ESTs contains 35 cloned genes and 11 unknown ESTs. By using Real-time Quantitative PCR, the expression level of Stat3 (2(-deltadeltaCT) = 0.16) , RIPX (2(-deltadeltaCT) = 0.18), ROD1 (2(-deltadeltaCT) = 0.23) and bcl-2 (2 (-deltadeltaCT) = 0.10) was lower in WCA group than that in control group respectively. The expression of Phospho-Stat3 (Tyr705) and bcl-2 in WCA group and 5-FU group was significantly decreased compared with the control group respectively.
CONCLUSIONChinese jianpi herbal recipe WCA could inhibit gastric cancer cell SGC-7901 growth in vivo. WCA could induce gastric cancer cell apoptosis and suppress proliferation. Its mechanisms might be involved in the down-regulation of Stat3, RIPX, ROD1 and bcl-2 gene.
