Objective To investigate the suppression effect of RNA interference(RNAi) on the expression of epidermal growth factor receptor(EGFR) of ovarian cancer SKOV3 cell line. Methods SKOV3 cells were transfected with synthetic EGFR sequence-specific dsRNA by lipofectamin 2000.The expression level of EGFR mRNA and protein were detected by RT-PCR and Western blotting,respectively.The proliferation of transfected SKOV3 cells was detected by WST-1 cell proliferation assay.The abilities of adhesion,migration and invasion were detected by cell adhesion assay,cell migration assay and Matrigel invasion assay,respectively. Results The suppression rates on EGFR mRNA and protein by sequence-specific dsRNA-EGFR were 73.65% and 58.94%,respectively.The cell proliferation was inhibited by 22.54%,35.76% and 31.07%,respectively at 24,48 and 72 h after transfection.The adhesion of sequence-specific dsRNA transfected SKOV3 cells for 30 min and 90 min were reduced by 12.11% and 18.66%,respectively.The migration and invasion of SKOV3 cells were decreased by 25.47% and 22.08%,respectively. Conclusion The down-regulation of EGFR expression of ovarian cancer by sequence-specific dsRNA can lead to the suppression of proliferation,adhesion,migration and invasion of ovarian cancer cells.

AIM:To study the changes of tear film and ocular surface after the coaxial incision 2.5mm and 3.0mm in the phacoemulsification.METHODS: Seventy patients (92 eyes) from February 2015 to February 2016 in our hospital were enrolled.The patients were randomly divided into two groups.Thirty-four patients (46 eyes) in Group A: coaxial 2.5mm incision phacoemulsification cataract extraction and intraocular lens(IOL) implantation.Thirty-six patients (46 eyes) in Group B: the conventional coaxial 3.0mm small incision phacoemulsification cataract extraction and IOL implantation.The break up time (BUT),Schirmer`s Ⅰ test (SⅠt) and lid-parallel conjunctival folds (LIPCOF) were assessed preoperatively and postoperatively.RESULTS: At 1wk,1 and 3mo postoperatively,the BUT in two groups decreased after operations,and the BUT of Group B was significantly lower than those of Group A,the differences were statistically significant (t=3.089,4.497,4.322;all P<0.05).The SⅠt in two groups increased after operations,the SⅠt of Group B was significantly higher than those of Group A and the differences were statistically significant (t=-6.286,-3.992,-3.278;all P<0.05).The LIPCOF score in two groups increased after operations,the LIPCOF score of Group B was significantly higher than those of Group A and the differences were statistically significant (t=-6.552,-5.131,-3.652;all P<0.05).At 6mo postoperatively,compared with the preoperative data,the BUT,SⅠt and LIPCOF score in Group A showed no statistically significant differences (t=0.646,0.551,0.165;P>0.05).The BUT,SⅠt and LIPCOF score in Group B showed statistically significant differences (t=-4.059,3.629,4.211;all P<0.05).CONCLUSION: Ocular surface has less damage and tear film has little influence at early stage after the coaxial 2.5mm incision phacoemulsmcation,compared with the conventional coaxial 3.0mm incision phacoemulsification surgery.
10.Study on effect of Xiaoaiping in enhancing efficacy of neoadjuvant chemotherapy for breast cancer and its mechanism.
China Journal of Chinese Materia Medica 2015;40(4):749-752
Traditional Chinese medicine (TCM) Xiaoaiping shows a pharmacological activity in treatment of breast cancer. Although neoadjuvant chemotherapy has been more and more widely used in treatment of breast cancer in recent years, no report has been made about the clinical efficacy and mechanism of the combined application of neoadjuvant chemotherapy and Xiaoaiping in treatment of breast cancer. In this study, 66 patients with breast cancer were selected and divided into the control group and the treatment group evenly with the random number table method. All patients received TEC neoadjuvant chemotherapy. On that basis, the treatment group also received the adjuvant therapy of Xiaoaiping injection (60 mL, i. v. , qd). The short-term response rate and the follow-up survival rate of the two groups were observed and compared. Surgical specimens of the patient were collected to observe and compare their expressions of estrogen receptor ER-α36 in breast cancer tissues with the immunohistochemical method. According to the findings, the overall response rate of the treatment group was 78.79%, which was significantly higher than that of the control group (57.58% , χ2 = 5.48, P < 0.05). Compared with the control group, the treatment group showed significant increases in the disease-free survival (DFS) rate and the total survival rate at the 3rd year and 5th year (all P < 0.05) , and a notable reduction in ER-α36 expression in breast cancer tissues (P < 0.05). Based on the our results, Xiaoaiping can significantly enhance short-term ad long-term efficacies of neoadjuvant chemotherapy for breast cancer. Its mechanism may be correlated with the inhibition of ER-α 36 expression in breast cancer tissues.
