Objective To investigate the biological features of epidermal growth factor receptor inhibitor AG1478 on cervical carcinoma cell. Methods The proliferation of HeLa cells under AG1478 stimulation was determined by CCK8 assay. The expression of EGFR downstream signaling protein and apoptotic relative protein were examined by Western blot and transcription of apotosis?related genes were measured by RT?qPCR in AG 1478 treated HeLa cells. Nuclear transport of phosphorylated ERK were measured through ICC assay. TUNEL assay was used to determine early stage of apoptosis. Results CCK8 assay showed that AG1478 inhibit the proliferation of HeLa cells and also block phosphorylated level of EGFR ,ERK and AKT. Furthermore ,nuclear transport of phosphorylated ERK upon EGF stimulation were blocked and pro?apoptotic proteins were up?regluated with activat ed cleaved Caspases. Conclusion AG1478 inhibited the proliferation and induced apoptosis in HeLa cells and it could be a potential therapeutic drug for cervical carcinoma.

ObjectiveTo explore the molecular mechanism of neural tube defects (NTDs) caused by hyperglycemia and thiadiazole and the antagonistic effect of taurine MethodsThe pregnant mice were divided into hyperglycemia groups, thiadiazole group,taurine groups and control groups The mRNA and the protein of Pax3 or Cx43 gene were detected respectively by reverse transcription-polymerase chain reaction assay and immunohistochemical method ResultsAs compared with mice treated by thiadiazole-stomach-perfusing, NTDs were significantly increased from mice treated with glucose-injection when blood glucose levels were ≥ 13 4 mmol/L Elevated glucose and thiadiazole could cause changes in Pax3 and Cx43 expression Hyperglycemia had stronger developmental toxicity on mice embryos Expression of Pax3 (mRNA 0 97?0 20, protein 0 11?0 02) in hyperglycemia group was significantly decreased, while expression of Cx43 (mRNA 7 05?1 63, protein 0 94?0 05) was significantly increased, and the relationship of dose-effect was demonstrated In the thiadiazole group, the expression of Cx43 (mRNA 6 96?0 73, protein 0 92?0 12) was significantly stronger than control groups, but there were no significant differences in expression of Pax3 between thiadiazole and its control groups Both of their teratogenicity could be antagonized by taurine ConclusionsThis study suggests that congenital malformation associated with diabetic pregnancy is caused by disruption of regulatory genes,Pax3 and Cx43 expression in embryo in response to elevated glucose Thiadiazole can only disturb the regulation of Cx43 gene causing NTDs Taurine can correct the disruption caused by the two teratogens

OBJECTIVE By investigating the incidence of nosocomial infection with objective monitoring method and prospective overall monitoring method, to analyze the advantage and significance between two methods. METHODS Using the objective monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2003 and using the prospective overall monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2002. All data were analyzed with Stata 7.0 soft. RESULTS There were 100 cases occurring nosocomial infection in 267 neurosurgical operation patients. The patient incidence of nosocomial infection was 37.5% and the rate of nosocomial infection cases was 50.9% with objective monitoring method, that was significant higher than those data coming from May to December in 2002 with 248 cases under prospective overall monitoring method, with which the patient incidence of nosocomial infection and the rate of nosocomial infection cases were 20.2%(50 cases ) and 21.4%(53 cases), respectively . Statistically significant difference was found (P

0.05).The average rate of three times NI prevalence surveys was 5.23% and that of NI prospective overall(monitoring) method in the same months was 6.60%,the statistical difference between them was found(P

OBJECTIVE To investigate the characteristics and risk factors of nosocomial infection(NI) in patients with hematological malignancies(HM),and provide the bases for making the controlling measures of NI.METHODS Using the targeted monitoring to study NI in patients with HM,and recording 14 factors such as the time of hospitalization,chemotherapy,count of leukocyte and absolute neutrophil count(ANC) and so on.The data were analyzed with unifactorial ?2 test and multifactorial Logistic-regression analysis.RESULTS Among 242 patients with HM the prevalence of NI was 35.5%(86/242) and the prevalence of NI time-cases was 52.9%(128/242).Among 86 patients of NI there were 27 patients occurred multiple sites NI(31.4%).The main infection sites were upper respiratory tract,gastrointestinal tract,lower respiratory tract,oral cavity and blood.66.7% Of NI happened in the period of chemotherapy and 7 days after chemotherapy.The time of hospitalization and ANC were independent risk factors of NI in patients with HM.CONCLUSIONS The patients with HM are susceptible population of NI,and NI often occurs in the period of chemotherapy and 7 days after chemotherapy.So medical staff should strengthen monitoring,and shorten the time of patient hospitalization and of recovery of ANC to reduce the prevalence of NI efficiently.

OBJECTIVE To analyze the bacterial distribution and drug resistance in lower respiratory tract nosocomial infection(NI).METHODS To investigate 351 patients suffered from lower respiratory tract NI using the prospective monitoring methods,and doing the pathogenic bacterium cultivation for sputums of 351 patients and then taking the susceptibility test.RESULTS Totally 346 pathogenic bacteria were found in sputums of 351 patients.The major pathogenic bacteria were Pseudomonas aeruginosa,Escherichia coli,Klebsiella and Staphylococcus aureus.ESBLs were 36.0% and 40.0%,respectively in E.coli and Klebsiella,and MRSA were 82.1% in S.aureus.Drug resistances were common in Gram-negative bacilli(GNB) and Gram-positive cocci.Piperacillin/tazobactam and cefoperazone/sulbactam and imipenem were the most sensitive for GNB,S.aureus,S.epidermidis and Enterococcus were all sensitive to vancomycin.CONCLUSIONS Drug resistance of the pathogenic bacteria in lower respiratory tract NI is common,so it′s necessary to emphasize pathogenic bacterium monitoring and use the antibacterials exactly.
