Objective To investigate the feasibility and clinical significance of fecal DNA tests for colon tumor diagnosis and screening,we inspected the mutations of APC,p53 and K-ras genes in the tissue and feces of patients with colorectal tumor.Methods We collected 46 patients with colorectal cancer(CRC),60 patients with colorectal adenomas( CRA) and 30 cases of normal person in Huizhou First People Hospital in Guangdong Province from Nov.2011 to Aug.2012.Then all the tumor tissues and feces of these people were detected the mu-tation rate about the APC,p53 and K-ras genes using polymerase chain reaction single strand conformation poly-morphism analysis method(PCR-SSCP).Results The mutation rates of APC,p53,K-ras genes of feces in CRC group,CRA group and normal group were 58.7%(27/46),65.2%(30/46)and 60.9%(28/46),20.0%(12/60),25.0%(15/60)and 23.3%(14/60),3.33%(1/30),0%(0/30)and 0%(0/30),respectively.How-ever the mutation rate in tissues were 63.0%(29/46),69.6%(32/46)and 63.0%(29/46),25.0%(15/60), 26.7%(16/60)and 26.7%(16/60),0%(0/30),0%(0/30) and 0%(0/30).Corresponding mutations could be found in feces and tumor tissues.Consistency checking for mutations rate in feces and tumor tissues of CRC group and CRA group showed that the Kappa value were 0.818(P<0.001),0.901(P<0.001),0.862(P<0.001)and 0.857(P<0.001),0.870(P<0.001),0.822(P<0.001).It means an excellent consistency.Con-clusion Fecal DNA testing is expected to become an effective noninvasive colon tumor early diagnosis and screening method.

The practice and exploration of bilingual teaching for the course of microbiology has been made in order to improve the students foreign lingual level and to meet the higher requirement on tip-top person with the social development. As a result,bilingual teaching is welcome,and the teaching effect is so distinct that the aim was reached to either study the fundamental knowledge or enhance the English level.

Objective To investigate the diagnostic parameters,criteria and diagnostic value of pelvic floor ultrasound in female stress urinary incontinence(SUI).Methods Simple factor logistic regression analysis was used to compare the difference of ultrasonic parameters between SUI patients(260 cases) and asymptomatic subjects(60 cases) to find the relevant diagnostic indexes,and to evaluate the diagnostic criteria and diagnostic value by the ROC curve.Results There were significant differences in urethral inclination angle and levator hiatus area in resting and bladder neck position,bladder position,urethral inclination angle,retrovesical angle,levator hiatus area in Valsalva state and urethral rotation angle,bladder neck mobility between the two groups (all P ＜ 0.05).There was no significant difference in age,BMI,bladder neck position,bladder position,retrovesical angle between resting in the two groups (all P ＞0.05).Using the ROC curve analysis,the cut-off points of urethral inclination angle and levator hiatus area in resting,bladder neck and bladder position,urethral inclination angle,retrovesical angle,levator hiatus area in Valsalva,bladder neck mobility and urethra rotation angle to diagnose SUI were 16.5°,13.5 cm2,3.5 mm,0.5 mm,29.5°,139.5°,19.5 cm2,24.5 mm,45.5°,respectively.The sensitivity/specificity were 54.6％/66.7％,49.2％/80.0％,68.1％/95.0％,64.2％/98.3％,67.3％/93.3％,73.5％/50.0％,68.8％/81.7％,70.0％/95.0％,67.2％/85.0％,respectively.The area under the curve were 0.625,0.668,0.855,0.854,0.817,0.622,0.811,0.866,0.817,respectively.Conclusions Pelvic floor ultrasound is a better way to diagnose stress urinary incontinence,and it provides an objective basis for the diagnosis of SUI.

BACKGROUND:Studies have shown that pulsed electromagnetism has a good effect in promoting peripheral nerve regeneration after cerebral infarction and spinal cord injury, and improving memory function in patients with neurological disorders. OBJECTIVE: To investigate the impact of pulsed magnetic field on brain function and endogenous neural stem cell factor in the brain tissue of rats with brain injury. METHODS: Totally 320 adult male Sprague-Dawley rats were randomly divided into model group, pulsed magnetic field 0.1 mT group, pulsed magnetic field 0.3 mT group and pulsed magnetic field 0.5 mT group (n=80 per group). After brain injury models were established using lateral hydraulic strike method, rats in the latter three groups were exposed to pulsed magnetic fields 0.1, 0.3, 0.5 mT, respectively. After electromagnetic radiation 1, 3, 7, 14 days, the motor function of rats was evaluated by beam-walking test and water maze test. Rats were intraperitoneally injected 5-deoxy-uridine (BrdU) at 1 day prior to different radiation time points, and BrdU and nestin expressions in the cerebral cortex were measured by immunohistochemical method. RESULTS AND CONCLUSION: (1) The time of water maze test and the beam-walking test at 1, 3 and 7 days after irradiation was ranked as follows: pulse magnetic field 0.5 mT < pulse magnetic field 0.3 mT < pulse magnetic field 0.1 mT < model group, and there were significant differences between groups (P < 0.05). (2) The expressions of BrdU and nestin at 1, 3 and 7 days after irradiation were highest in the pulse magnetic field 0.5 mT group, successively followed by pulse magnetic field 0.3 mT group, pulse magnetic field 0.1 mT group and model group (P < 0.05). In summary, the pulse magnetic field exhibits remarkable protective effects on the brain function of rats with craniocerebral injury in an intensity-dependent manner. The possible mechanism is related to the activation of neural stem cells and the proliferation of neural stem cells in the brain tissue of rats with craniocerebral injury.

BACKGROUND: Genetic variations of the 5-lipoxygenase activating protein and leukotriene A4 hydrolase genes that confer an increased risk of ischemic stroke have implicated the family of leukotrienes as potential mediators of ischemic stroke. This study aimed to explore the association of ALOX5,LTA4H andLTC4S gene polymorphisms with ischemic stroke risk in a cohort of Chinese in east China.METHODS: This case-control study consisted of 690 patients with ischemic stroke and 690 controls. Polymorphisms ofALOX5 rs2029253 A/G,LTA4H rs6538697 T/C, andLTC4S rs730012 A/C were genotyped by the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis. The multivariate logistic regression model was used to exclude the effects of conventional risk factors on ischemic stroke.RESULTS: Carriers of C allele in rs730012 were more susceptible to ischemic stroke (OR: 1.37; 95%CI: 1.08-1.73;P=0.009). The rs2029253 GG genotype showed a risk-reducing effect on ischemic stroke (OR: 0.72; 95%CI: 0.55-0.93;P=0.013) while the rs6538697 CC genotype had an increased risk of ischemic stroke (OR: 1.77; 95%CI: 1.09-2.89;P=0.022). The rs730012 variant was not associated with ischemic stroke risk after adjusting confounding factors (P>0.05).CONCLUSION: The present study suggested that gene polymorphisms in the leukotrienes pathway may exert infl uences, with independent genetic effects, on ischemic stroke susceptibility in a cohort of Chinese in east China.
