Objective To explore a stable and feasible method for the primary culture of breast cancer-associated fibroblast (CAF), and to offer the theoretical basis for the further studies about the role of CAF in the processing of breast cancer by analyzing the biological property of CAF. Methods CAF was primary cultured with tissue block enzymolytic method. Flow cytometry (FCM) was used to detect the cell cycle. The expression of Vimentin, α-SMA and Ki-67 were detected by cell immunochemistry method. Transwell assay was used to detect the invasion and migration capacity of CAF. Results The CAF was successfullyculturedbyconditionoptimization.ImmunohistochemicalresultsshowedthatVimentin, α-SMA and Ki-67 were highly expressed in CAF.Comparedwithfibroblastsfrombreastcancersidestissues,the proliferating ability and the invasion and migration capacities of CAF were enhanced (number of invasive cells: 79.7 ± 3.5 vs. 66.3 ± 1.5, number of migrated cells: 242.3 ± 3.1 vs. 218.3 ± 2.1, both P<0.05). Conclusion CAF cultured from breast cancer has better proliferating ability and strong invasion and migration capacities.

BACKGROUND:It is crucial for us to find an objective and sensitive means for the assessment ofthe severitv and development of dementia,so as to make instant diagnosis and examination of therapeutic effect on patientswith vascular dementias(VD).Event related potential endogenetic eomponent P300 is proved closely correlated with the cognitive management of examinees but not with stimulus property,thereby considered as one of the most valuable and objective index for brain superior psychological activity.OBJECTIVE:To study the role and significance of events related potential P300,providing objective basis for clinical diagnosis and therapeutic assessment for patients with VD.DESIGN:Non-randomized simultaneous controlled explorative study based on patients. SETTING:Neurological department and electromyography department in aprovincial hospital and neurological department in a medical college hospital.PARTICIPANTS:Between February 2000 and June 2001,64 patients were of VD at neurological clinic and ward ofthe Second Affiliated Hospital of Chongqing Medical College,including 38 males and 26 females with theaverage age of(66.0±4.6)years(VD group).Culturallevel:19 cases re-ceiyed over senior school education,31 cases of junior school education and14 cases of illiteracy.Meanwhile 60 inpatients without VD were enrolled(non-VD group)including 35 males and 25 females withthe average age of(68.0±3.7)years.Culturallevel:senior school or above,15 cases,junior school, 29 cases and illiteracy,16 cases.METHODS:Mental sate of both VD and non-VD groups were assessed with mini-mental state examination(MMSE),and tested with P300 potential observing the variability of latency and amplitude of P300 in patients.Both methods were compared between VD group and non-VD group, moreover relationship between P300 latency and MMSE scores was also explored.MAIN OUTCOME MEASURES:Variability of P300 latency and amplitude Relationship between P300 latency and MMSE scores.RESULTS:P300 latency was found prolonged in 74% and 7% of VD group and non-VD group respectively,with obvious significance between them,meanwhile prolonged P300 latency was proved closely correlated with the MMSE scores(r=0.609 6,P<0.05).CONCLUSION:P300 latency can be considered as an obiective predictor for the earlier diagnosis and the assessment of therapeutic effects in patients with VD.

ING1 family is a candidate for tumor suppressor,which has three splicing isoforms named p47ING1a,p33ING1b,and p24ING1c. Study of the effect of different isoforms of ING1 on HeLa cells proliferation and its molecular mechanism would help further identifying the functional relationship of ING1 isoforms,and finding important genes regulated by ING1. Cell growth curve and cell cycle analysis were used to observe the effect of ING1a,ING1b,and ING1c on HeLa cells growth,and the result indicated that they could all inhibit HeLa cells growth by arresting cell cycle at G0/G1 phase. PCR method was used to construct the PHD domain deletions of ING1a and ING1b. ING1a,ING1b,ING1c and the PHD domain deletions 1a?C and 1b?C were then overexpressed in HeLa cells. p16INK4a,PTEN/p27Kip1 and p53/p21Waf1 protein levels were detected by Western blot. The result showed that ING1a,ING1b,ING1c,and 1a?C except for 1b?C induced p16INK4a protein expression,in which ING1c had the most powerful effect. Luciferase assay identified that overexpression of pcDNA3.1(+)-1a?C facilitated p16INK4a transcription through enhancing p16INK4a promoter activity,while pcDNA3.1(+)-1b?C repressed the p16INK4a promoter activity . In a word,it was found for the first time that except for the p53/p21Waf1 pathway,three splicing isoforms of ING1 family could also inhibit HeLa cells proliferation though upregulation of p16INK4a and PTEN,and the PHD domain deletion of ING1a enhanced p16INK4a transcription. These findings provide new clews to further study on the mechanisms of ING1 family suppressing cancer cells growth.

OBJECTIVE To analyze the pathogens distribution and the antibiotic resistant characters.METHODS Sputum culture was performed in 267 cases who suffered from lower respiratory tract infection in emergency ward from Jan 2004 to Jun 2007.The results of 183 pathogens and drug sensitivity were analyzed.RESULTS The detected 183 strains of pathogens showed that Gram-negative bacilli accounted for 77.1%(Klebsiella pneumoniae was in the first place) and Gram-positive cocci were for 22.9%(Enterococcus faecium and Staphylococcus aureus were in the first places),the total drug resistance rate of Gram-negative bacilli to gentamicin,cefazolin,SMZ/TMP,piperacillin,ciprofloxacin and aztreonam had highly reached 60.5-70%,however to meropenem,cefepime,amikacin,imipenem and Sulperazone was 32.5-38.6%.Gram-positive cocci appeared generally higher multidrug resistant,the drug resistance rate of Gram-positive cocci to penicillins and erythromycin was all 100%,but the resistantce of Gram-positive cocci to vancomycin hadn′t been found.CONCLUSIONS Gram-negative bacilli are major pathogens in lower respiratory tract infection of emergency ward,K.pneumoniae is in the first place of Gram-negative bacilli and E.faecium and S.aureus are in the first places of Gram-positve cocci,both of them appearing highly multidrug resistant,analysis of pathogens and drug sensitivity are necessary to rational antibiotics usage,and the immunological protection should be enhanced.

Objective To explore the value of preoperative D-dimer in patients with gastric cancer in judging gastric cancer metastasis and assessing prognosis.Methods Clinicopathological data of 132 patients with gastric cancer in the First Affiliated Hospital of Anhui Medical University between Jan.2010 and Jan.2011 was analyzed retrospectively in this study.All patients were divided into two groups according to the cutoff value (1.465 mg/L)of D-dimer and the relationships between D-dimer and clinicopathological data were determined by chi-square test.Moreover,the association of preoperative D-dimer and the prognosis was analyzed by Kaplan-Meier analysis and Log-rank test.Univariate and multivaritate Cox model were used to analyze the factors which might affect the survival of the patients and significant independent factors.Results A total of 132 patients were enrolled in this study in accordance with the inclusion criteria.D-dimer was positively correlated with the depth of invasion (x2 =4.996,P < 0.05),age (x2 =4.311,P < 0.05) and distant metastasis of gastric cancer (x2 =16.641,P <0.01),but not with thc gcndcr,lymph node metastasis,tumor size,the degree of differentiation and TNM stage (P > 0.05).The mean D-dimer level was (1.39 ± 0.7) mg/L in distant metastasis patients and (0.97 ±0.83) mg/L in non distant metastasis patients (P =0.023),the mean plasma D-dimer level in patients alive at the 5 years after the surgery was (0.78 ± 0.58) mg/L,which was significantly lower than the amounts determined for the deceased patients (0.75 ± 0.58) mg/L (P < 0.01).The Kaplan-Meier curves showed that the patients with gastric cancer had a longer time in the low D-dimer group than in the high D-dimer group,showing a significant difference between the two groups (P < 0.01).Univariate analysis showed that the overall survival rate was significantly correlated with the gender,D-dimer,tumor size,the depth of invasion,lymph node metastasis and TNM stage (P all < 0.05).The D-dimer was proved to be independent risk factor for the prognosis of gastric cancer by multivariate analysis(P < 0.05).Conclusion According to the analysis,D-dimer may be valuable biomarker for metastasis patients,besides,D-dimer was an independent prognostic factor for patients with gastric cancer.
