Targeted therapy such as the epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)has made huge progress in treatment of non-small cell lung cancer (NSCLC).However,the emergence of acquired drug resistance is an inevitable result of the targeted therapy.The hepatocyte growth fac-tor/c-mesenchymal-epithelial transition factor (HGF /c-Met)signaling pathway participates in cell formation, migration,angiogenesis and other important cellular processes of multiple tumors.The abnormal activation of this signaling pathway plays the pivotal role in the acquired resistance to EGFR-TKI.Recently,some clinic tri-als prove that HGF /c-Met inhibitors can make clinical benefit of some NSCLC patients with acquired drug re-sistance of EGFR-TKI.

Objective: To investigate the effect of low-dose paclitaxel combined with thalidomide on angiogenesis in mice bearing S180 sarcoma. Methods: An S180 sarcoma-bearing mouse model was established. Forty tumor-bearing mice were randomly divided into four groups: A, the control group, administered normal saline; B, the paclitaxel group, administered 20 mg/kg paclitaxel by intraperitoneal injection three times per week for 2 weeks; C, the thalidomide group, administered 200 mg/kg thalidomide by gavage three times per week for 2 weeks; and D, the paclitaxel + thalidomide group, administered paclitaxel (20 mg/kg) and thalidomide (200 mg/kg) by intraperitoneal/intragastric administration three times per week for 2 weeks. Tumor weight, tumor inhibition rate, microvascular density (MVD), and vascular endothelial growth factor (VEGF) expression were measured. Results: Tumor weight, VEGF expression, and MVD were lower in groups B, C, and D (P<0.05) than in the control. VEGF expression and MVD were lower in group D than in groups B and C; these differences were statistically significant (P<0.05). Conclusions: Low-dose paclitaxel combined with thalidomide exerted an inhibitory effect on vascular growth in S180 sarcoma.

Background The palate is differently regulated and developed along the anterior-posterior axis. The Bmp signal pathway plays a crucial role in palatogenesis. Conditioned-inactivation of Bmp type I receptor Alk2 or Alk3 in the neural crest or craniofacial region leads to palatal cleft in mice. However, how different Bmp members are involved in palatogenesis remains to be elucidated. In the present study, mRNA expression patterns of Bmp2, Bmp3 and Bmp4 in the developing anterior and posterior palates were examined and compared, focusing on the fusion stage. Methods To detect the expression of Bmp mRNA, antisense riboprobes were synthesized by in vitro transcription. Radioactive in situ hybridization was performed on sagital and coronal sections of mice head from E13 to E18. Results The expression of these Bmps were developmentally regulated in the anterior and posterior palates prior to, during and after palatal fusion. During palatal fusion, Bmp4 expression shifted from the anterior to the posterior palate, Bmp2 was highly expressed in both the anterior and posterior palates in this process, whereas Bmp3 was only localized in the posterior palate. They showed generally non-overlapping pattern in their expression domains. Thereafter, their expression was detected in both the anterior and posterior palates regulating osteogenesis and myogenesis respectively. Conclusions Bmp signalling is involved in palatogenesis in multiple stages and has multiple roles in regulating anterior and posterior palatal development. Disturbances of Bmp signalling during palatogenesis might be a possible mechanism of cleft palate.

Objective To differentiate Chinese medical syndromes of chronic renal Failure by objective laboratory indexes. Method Data of 312 cases were collected through a retrospective survey and these cases were divided into five Chinese medical syndromes according to an authorized criterion. Laboratory examination indexes of all syndromes were disposed with analysis of variance and discriminant analysis in turn. Result Discriminant functions of four syndromes were worked out and the accuracy of the functions was 60%. Conclusion Differentiation of Chinese medical syndromes should use modern techniques for reference on the base of traditional methods. And through it, a new way even a new system of diagnosis for Chinese medical syndromes in which traditional and modern methods are perfectly combined may be found out.

Objective To investigate the correlation between preoperative anxiety and emergence agitation(EA)in children after sevoflurane anesthesia.Methods A total of 120 children who were going to receive an elective surgery were recruited in this study.The preoperative anxiety in these children was measured through the Modified Yale Preoperative Anxiety Scale(mYPAS)at the following time:during the preoperative interview(T1),waiting period in surgery waiting room(T2),after the children entered the operating room(T3)and at the beginning of sevoflurane inhalation induction(T4).The emergence agitation(EA)scores were obtained by using the Pediatric Anesthesia Emergence Delirium(PAED) Scale after the surgery.Results After adjusting for the effect of age,it was found that the anxiety scores at T1 and T2 had no significant correlation with EA,while those in T3 and T4 showed a statistically significant correlation with EA.The level of anxiety at the beginning of induction showed a strong positive correlation with EA,and the correlation coefficient was 0.708(P<0.01).Conclusion The preoperative anxiety in the operating room and at the beginning of induction of anesthesia is correlated with EA in children receiving sevoflurane anesthesia.
