Objective To exPlore the effect of mammalian target of raPamycin ( mTOR ) inhibitor eVerolimus on radiosensitiVity of human non_small cell lung cancer cell line in vitro by using eVerolimus to inhibit mTOR signaling Pathway of A549. Methods Human non_small cell lung cancer cell line A549 was subjected to radiation alone or in combination with eVerolimus treatment. The 50%inhibition concentration ( IC50 ) of eVerolimus in A549 cells was detected by methylthiazol tetrazolium ( MTT) assay in vitro. EVerolimus at the 20%inhibition concentration ( IC20 ) was used to Pretreat A549 cells for 24 h. Cells were then irradiated by X_ray with 2,4,6,8 Gy. The cell surViVal fraction was comPuted by clone formation. Cell surViVal curVe was fitted by multitarget one_hit model, and mean lethal dose ( D0 ), dose quasithreshold ( Dq ), surViVal fraction at 2 Gy ( SF2 ), and sensitization enhancement ratio (SER) were calculated. The exPression ofγ_H2AX was determined by Western blotting and then the relatiVe gray Values were analyzed. Results EVerolimus significantly imProVed the sensitiVity of A549 cells to radiation. The D0 , Dq and SF2 of eVerolimus+irradiation grouP were significantly lower than those of irradiation grouP. The SER was 1. 36. The residual amount of γ_H2AX Protein in the eVerolimus + irradiation grouP was significantly higher than that of the irradiation grouP. Conclusion EVerolimus inhibiting mTOR signaling Pathway can increase the radiosensitiVity of A549 cells.

This study is to explore characteristic indexes in evaluation criteria for rat skin anaphylactoid test comparing skin blue spot OD values at the treated position and the control position in the same animal. Common contrast agents, traditional Chinese medicine injections and injections' active pharmaceutical ingredients or excipients in the existing clinical anaphylactoid reaction reports were taken as test drugs in the rat skin anaphylactoid test to define the K value: K > 2 represents positive anaphylactoid reaction, 1.2 ≤ K ≤ 2 represent doubtable anaphylactoid; K < 1.2 represents negative anaphylactoid reaction, which were taken as the criteria for evaluating anaphylactoid of tested drugs. The evaluation result and that for classic criteria were compared to study the applicability of K value. According to the comparison, K value, as the evaluation criteria in the rat skin anaphylactoid test, can more truly reflect the actual situation of skin aizen and minimize the error caused by animal individual factors. Compared with positive and negative two-level criteria for blue spot diameter, K value's positive, doubtable and negative three-level criteria are more objective and accurate. Therefore, K value can be used as the evaluation criteria in the rat skin anaphylactoid test.

OBJECTIVETo explore the effect of Shengjiang Xiexin Decoction (SXD) on the intestinal mucosal and functional cells of rats after irinotecan (CPT-11) chemotherapy.

METHODSTotally 24 healthy Sprague-Dawley (SD) male rats were divided into three groups, the normal control group, the CPT-11 group, the SXD combined CPT-11 group according to random digit table, 8 in each group. CPT-11 was injected at the daily dose of 150 mg/kg to rats in the CPT-11 group and the SXD combined CPT-11 group from the caudal vein on the 4th day, once daily for 2 successive days to duplicate delayed diarrhea model. Equal volume of normal saline was injected to rats in the normal control group from the caudal vein. SXD at 2 g/mL (10 g/kg body weight) was administered to rats in the SXD combined CPT-11 group by gastrogavage for 9 successive days. Deionized water was administered to rats in the CPT-11 group and the normal control group. Diarrhea was observed at 48, 60, 72, 84, 96, and 108 h to calculate the incidence rate of diarrhea. Meanwhile, scoring for diarrhea was performed by referring methods of Akinobu Kurita. Rats were killed on day 10, ileum, cecum, and colon tissues were collected and fixed in 10% formalin solution. HE staining was performed. Intestinal mucosa injuries were graded under light microscope according to the criterion of Chiu's score. The expressions of goblet cells and Paneth cells were observed by PAS stain. Enteroendocrine cells were observed by immunohistochemical CgA staining. Positive cells were counted and cumulative optical density (IOD) analyzed by Image-Pro-Plus 6.0.

RESULTSNo diarrhea occurred in rats of the normal control group at each time point. The incidence rate of diarrhea was 75.0% (6/8) at 48 h, 100.0% (8/8) at 60 h, 100.0% (8/8) at 72 h, 87.5% (7/8) at 84 h, 75.0% (6/8) at 96 h, and 75.0% (6/8) at 108 h in the CPT-11 group. The incidence rate of diarrhea was 25.0% (2/8) at 48 h, 50.0% (4/8) at 60 h, 12.5% (1/8) at 72 h, 0.0% (0/8) at 84 h in the SXD combined CPT-11 group. Compared with the same group at 60 h, scores for diarrhea at 48, 84, 96, and 108 h obviously decreased in the CPT-11 group, and scores for diarrhea at 48, 72, 84, 96, and 108 h obviously decreased in the SXD combined CPT-11 group (P < 0.05, P < 0.01). Compared with the same group at 72 h, scores for diarrhea at 84, 96, and 108 h obviously decreased in the CPT-11 group (P < 0.05, P < 0.01). Compared with the normal control group, scores for diarrhea increased in the CPT-11 group at each time point (P < 0.01); grading of ileum, cecum, and colon mucosal tissues increased (P < 0.05, P < 0.01); expressions of ileum and cecum mucosal epithelial goblet cells obviously decreased (P < 0.05); the number and expressions of ileum and cecum mucosal epithelial Paneth cells increased (P < 0.01). Expressions of ilium endocrine cells increased, while those of cecum and colon endocrine cells decreased in the CPT-11 group (P < 0.01). Compared with the CPT-11 group, scores for diarrhea were obviously lowered (P < 0.05, P < 0.01), grading of ileum, and cecum mucosal tissues decreased (P < 0.05, P < 0.01); expressions of ileum, cecum, and colon mucosal epithelial goblet cells obviously increased (P < 0.05, P < 0.01); the number and expressions of ileum cecum mucosal epithelial Paneth cells increased (P < 0.05); expressions of cecum and colon endocrine cells increased (P < 0.05, P < 0.01) in the SXD combined CPT-11 group.

CONCLUSIONSXD played roles in preventing and treating CPT-11 induced delayed diarrhea by improving CPT-11 chemotherapy induced apoptosis and necrosis of intestinal mucosal and functional cells.
