Objective To evaluate the diagnostic value of color Doppler blood flow imaging(CDFI) combined with two dimensional ultrasonography in the early breast cancer.Methods Forty five cases of breast mass(≤2 cm) were studied with CDFI and two dimensional ultrasonography.Results There were 21 cases with breast cancer and 24 cases with benign breast masses rich blood flow was demonstrated in 20 cases of breast cancer and in only seven cases of benign breast mass on CDFI.The Resistance index(RI)in the breast cancer group was higher(0.70?0.06)than that in benign breast mass group(0.60?0.06)(?

As the impact of molecular and genomic data grows in epidemiology,numerous studies of genetic epidemiology and post-genomics research rely increasingly on the use of human biobanks.Biobanking ranges in scope from small collections of samples in academic or hospital settings to large-scale national repositories.In this context,the construction of biobank is confronting With numerows ethical challenges,informed consent in particular.The paper analyses several concent moder of participation in biobank and explores the optinal model of China——opt-out.

Objective To develop a liquid chromatography-tandem mass spectrometry (LC-MS/MS) screen-ing method for 45 poisonous alkaloids in blood. Methods Identification was based on the compound’s retention time and two precursor-to-production transitions. The method involved a liquid-liquid extraction (LLE) followed by LC-MS/MS with multiple-reaction monitoring (MRM). When 1 mL of blood was ex-tracted with diethyl ether at pH=9.2 with SKF525A as the internal standard, the target compounds were an-alyzed with LC-MS/MS in the positive ionization mode. Results The target alkaloids had good linearity (r>0.995 1), both the intra-day precision and inter-day precision being less than 14.77%. The limits of detection ranged from 0.05 to 25 ng/mL in blood. Conclusion The method is selective and sensitive in detecting poisonous alkaloids with a total running time of 12 minutes; therefore it was successfully ap-plied to some actual cases of suspected alkaloids poisoning.

Objective To explore the risk factors for school age chidren dental fluorosis in high fluoride rural areas.Methods Based on the fluoride screening results of rural drinking water in Shandong in 2006,three villages of Jiaxiang counties were selected as the survey sites,12 drinking water samples were collected and pH value,fluoride,hardness were determined,110 school-age children were chosen among high fluoride countryside in May,2008.Dental fluorosis was examined,and a questionnaire survey was performed.Results The average levels of pH value,fluoride content and hardness were 7.01,1.24,494.00 mg/L respectively,and the of dental fluorosis was 63.6%.Simple Logistic regression analysis showed that the prevalence of dental fluorosis was associated with Lower family income,lower education level of parents,lower nutrition knowledge score and few kinds of daily food.Multiple Logistic regression analysis showed that the prevalence of dental fluorosis was positively associated with family income,education level of father and consumption of meat,milk,eggs,fresh vegetables and fruit.Conclusion The rate of dental fluorosis among school-age children in the investigated area is higher.Family income,parents'education and nutritional deficiency are related to the prevalence of dental fluorosis.

Objective To explore the correlative factors of mental disorder in patients with head injury. Methods 255 subjects sustained with head injury and survived from traffic accident in Chengdu were assessed with Structured Clinical Interview for DSM-Ⅳ axis Ⅰ disorders (SCID-I/P) , Personality Disorder Questionaire for CCMD-2-R(PDQC), Structured Clinical Interview for CCMD-2-R(SCICP), WAIS-RC, WMS, brain electric activity mapping (BEAM) after completion of clinical management. Based on the diagnostic criteria of organic mental disorder in CCMD-3, mental disorders in 255 subjects were diagnosed. Results The incidence of mental disorders in the patients with head injury was 72.5% (185/255). Mental disorders in patients with head injury were correlated with educational level, type and severity of the head injury, or injuries involving the left frontal lobe injury, the left temporal lobe or multiple lobes and BEAM abnormality. Conclusion The incidence of mental disorder is high in the patients with head injury. Educational level, type and severity of the head injury, the location of the injured brain, injury involving multiple lobes of the brain may affect morbidity of mental disorders in patients with head injury.

Objective To analyze the cognition, utilization and satisfaction on pregnancy health management of basic public health services. and to find out potential problems and provide suggestions for promoting equality in rural basic public health. The Weishan Lake area was selected as the sample point and the left behind pregnant women in the countryside as control. Methods In the period from May 2016 to July, questionnaires were designed for the pregnancy health management of basic public health services, 330 left-behind pregnant women and 300 rural immigrating pregnant women were selected as our target interviewees. The average age of rural immigrating pregnant women and the left-behind pregnant women was (28.6 ± 3.7) years, and (28.3 ± 3.4) years old, respectively; the degree of education of rural immigrating pregnant women and the left-behind pregnant women was secondary specialized school or high school and junior middle school, respectively. The occupation of rural immigrating pregnant women was mainly workers;accounting for 31.4%, while the occupation of the left-behind pregnant women was farming, accounting for 36.7%. Results The awareness rate ofgeneral pregnancy examination and gynecological examinationin health management items of rural immigrating pregnant women and left-behind pregnant women was the highest, which were 77.7% and 78.3%, respectively, and the lowest awareness rate of the 2 prenatal follow-up was the lowest in the third trimester, which was 22.6% and 23.0%, respectively. The difference was not statistically significant. The maternal health management service understanding rate of rural immigrating pregnant women and left-behind pregnant women were 24.7% and 17.9% respectively , the difference was statistically significant (Z=-1.993, P=0.046);the awareness rate of delivery and breastfeeding in late pregnancy were 36.2% and 47.6% respectively, and the difference was statistically significant (χ2=7.933, P=0.005). The rate of the registering of the maternal health care handbook of rural immigrating pregnant women and left-behind pregnant women were 40.4%and 54%respectively, and the difference was statistically significant (χ2=11.065, P=0.001), Among them, the rate of registering in township hospitals was 46.6% and 73.3% respectively, and the difference was statistically significant (χ2=21.104, P=0.0000); the utilization rate of 3 or more antepartum examination and follow-up services was 8.4%and 23%respectively, and the difference was statistically significant (χ2=23.878, P=0.000). The growth and development of the health of pregnant women and fetal assessment and utilization rates were 9.8% and 23.6%, the difference was statistically significant (χ2=20.460, P=0.000); prenatal guidance (childbirth preparation, breastfeeding) utilization rate were 8%, 13.7%, the difference was statistically significant (χ2=5.011, P=0.027);abnormal or critical maternal referral utilization rate were 22%and 34.8%, the difference was statistically significant (χ2=12.133, P=0.001). Conclusion Imbalance exists in acquiring basic public health services of the two pregnant women cohort, the left-behind pregnant women are better than the rural immigrating pregnant women. Therefore, the government should propagate this service by multi-channel to improve their cognition and utilization of this policy implemented, and to promote the development of the services.
