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 and purpose:miR-124 is considered to be a tumor suppressor in multiple tumors, including lung cancer, prostate cancer, bladder cancer, and breast cancer. However, its function is unclear in gastric cancer. This study aimed to explore the expression of miR-124 in human gastric mucosal epithelium cells and different gastric cancer cells, as well as gastric cancer tissues and matched para-cancerous tissues. The correlations of miR-124 expression with gender, age, histological grade, T stage, TNM stage, lymph node metastasis and prognosis of gastric cancer patients were analyzed.Methods:A real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) was employed for detecting the expression of miR-124 in human gastric mucosal epithelium cells and gastric cancer cells. The expression of miR-124 in gastric cancer tissues and matched para-cancerous tissues was detected by in situ hybridization.Results:The RTFQ-PCR results indicated that the expression of miR-124 was down-regulated in MKN-74, MKN-28, MKN-45, MGC-803, SGC-7901 and AGS cells compared to GES-1 cells.In situ hybridization showed that miR-124 was strongly expressed in normal gastric mucosa. However, low expression, focal positive expression or lack of miR-124 expression were observed in gastric cancer tissues. Statistical analysis showed that miR-124 was close-ly correlated to histological stage, TNM stage and node metastasis of gastric cancer patients, but not the age, gender and tumor size. The OS and DFS of the patients with low expression of miR-124 were shorter than that of the patients with high expression of miR-124. Multivariate analysis suggested that miR-124 down-regulation was an independent prog-nostic factor for survival in patients with gastric cancer.Conclusion:miR-124 is down-regulated in gastric cancer cells and tissues. The expression of miR-124 is correlated to histological stage, TNM stage, node metastasis and prognosis.

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.

Aim To elucidate the biochemical mechanism of gossypol in inducing the decline of sperm quality.Methods Gossypol was administered orally at the dose of 50 mg?kg-1/2 d for two weeks.Then,the sperm was collected from the left caudal epididymis and was analysed by CASA.The morphological changeand the concentration of nitric oxide(NO)in testes as well as the level of hormone〔follicle-stimulating hormone(FSH)〕,luteotrophic hormone(LH),testosterone(T)in serum were assayed.Results Gossypol could induce the decrease of sperm number and sperm quality.The concentration of NO in testes increased significantly.Among the three kind of hormone,only the concentration of T showed decrease after the oral administration of gossypol.NA1108 could antagonize the decline of sperm quality damaged by gossypol and decrease the content of NO in testes.Conclusions The concentration of NO in testes beyond normal value was one of the toxic mechanism of gossypol that contributed to the inhibition of spermatogenesis.Some drugs with the ability to reduce NO content in testes could also increase sperm quality.

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.
