Objective:To explore the influencing factors on patients' health seeking behavior in rural China by employing the theory of planned action.Methods:Data from cross-sectional household-based health survey carried out in 2008 were used in the study.Correlations between outcomes and explanatory variables were studied by Logistic regression.Results:The studying population included 19 389 adult patients over the age of 15.Illness awareness,medical experience and structural restriction factors had strong effect on whether the patients chose medical service.Pepople in different socioeconomical status suffered different influences.Conclusion:Responding to the changing trend of health service demand among rural residents,we should recognize the differentiation and allocate the healthcare resources more rationally.

Objective To study the effects of directional inducement of factors produced by injured sciatic nerve on the regenerating axons of adult frog in vivo. Methods Conditioned medium with fraction of 30kD to 100kD was obtained from sciatic nerve of adult frog and pumped out and formed a gradient of concentration toward the end of central nerve stump of cutaneous pectoris nerve with different distances and angles by miniosmotic pumps.After 28\|35 days,the chest tissue was dissected and stained with immunocytochemistry to show the regenerated motor\|axons and the directional value is analyzed. Results The regenerated motor axons grew obviously towards the tip of the cannula with high concentration of CM.The directional value is 0\^84 whereas the value is 0\^04 with random direction.The average directional value between the two groups is significant and is not influenced by the distances and angles of the cannula to the nerve stump. Conclusion Damaged peripheral nerve can produce diffusible active factors with molecular weight between 30kD to 100kD,which induce the directional outgrowth of regenerating motor axons from sectioned nerve stump of adult frogs in vivo.

Objective To know the effect of water supply improvement on prevention and control of the endemic arsenism. Methods 35 residents aged 45-65 years (21 male, 14 female) in a high arsenic area were selected for determination of urine arsenic, 21 residents aged 45-65 years (14 male, 7 female) in another high arsenic area for determination of hair arsenic and the residents in the control area were also selected. Results 16 years after the water supply improved (concentration of arsenic

OBJECTIVE:To observe clinical efficacy and safety of Zishen jianpi huoxue decoction combined with Xiaoxintong capsule in the treatment of type 2 diabetes complicating with silent myocardial ischemia (SMI). METHODS:126 patients with type 2 diabetes complicating with SMI were selected and randomly divided into control group(62 case)and observation group(64 cases). Both group were given diet guidance and hypoglycemic drugs as sulfonylureas,biguanides. Control group was given Xiaox-intong capsule 10 mg,tid;observation group was additionally given Zishen jianpi huoxue decoction 400-500 ml,bid. Both groups received treatment for 7 d. Therapeutic efficacy of thoracic obstruction,improvement of coronary artery branch stenosis and times and duration of electrocardiogram ST segment low voltage outlet were observed in 2 groups. ADR was compared between 2 groups. RESULTS:Therapeutic efficacy of thoracic obstruction and improvement of coronary artery branch stenosis in observation group were significantly better than in control group,with statistical significance(P<0.05);the times and duration of electrocardiogram ST segment low voltage outlet in observation group were significantly lesser shorter than in control group,with statistical signifi-cance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Zishen jianpi huoxue decoction complicating with Xiaoxintong capsule shows significantly therapeutic efficacy in the treatment of type 2 diabetes complicating with SMI with good safety.

Objective: To investigate the problems and improve the quality of experimental teaching for medical laboratory instruments.Method: A questionnaire was made among 100 laboratory medicine students in Chongqing University of Medical Sciences.Result: About eighty-six percent of the students were satisfied with the experimental teaching for medical laboratory instruments,but there were still problems: absence of clear objectives in experimental teaching;shortage of activity of medical laboratory instruments experiment;lack of modern large-scale instruments.Conclusion: the key points to improve experimental teaching quality are to set up clear experimental teaching objective;update instruments for experimental teaching;structure simulator laboratory with modern education simulator technology.

Students will be familiar with the major contents of clinical laboratory management,such as clinical laboratory quality management,laboratory creature safety containment,clinical laboratory accredit action through the course of clinical laboratory management for laboratory medicine students.Meanwhile,by continuously perfecting the teaching contents and methods,students' satisfaction with this course has been improved,and they pay more attention and give higher appraisement to this course.

Objective To investigate the characteristics of electroencephalograms ( EEGs ) of patients with childhood absence epilepsy ( CAE ) .Methods EEG of 46 patients with CAE were analyzed .Results Of 46 patients,there were 44 cases (95.6%) with guided bilateral symmetry 3Hz spike-and-wave.16 cases were character-ized by multiple spike-and-wave on the 3Hz spike and slow wave;and the centrotemporal spikes was found in 1 case. Additionally,the 3Hzδactivity in occipital region has been traced in 34 cases of these 46 patients.Conclusion In general,the EEGs of CAE patients have typical characteristics ,and few of them showed atypical manifestation ,which must be verified by clinical attention .

Gastrin is mainly secreted by the G cells in antrum and the upper part of small intestine.Gastrin receptor distributes in various tissues.Gastrin and its receptor have several functions including regulating cell growth and differentiation,inhibiting apoptosis,promoting cell proliferation,invasion and metastasis.Studies have shown that gastrin and its receptor involve with various cancers occurrence and development.Gastrin and its receptor can be used to diagnosis early gastric cancer,and be used as a potential targets in gastric carcinoma treatment.The relationship of gastrin and its receptor with gastric carcinoma were reviewed in this paper.

Objective:To verify the association between social determinants and the quality of life ( QoL) among the elderly in Beijing .Methods:A questionnaire household survey was conducted and 1 685 over 60 dwellers in Beijing were interviewed .The EQ-5D scale was used to measure the elderly ’ s QoL and Time Trade-off model was used to calculate the EQ-5D index.Multiple linear regression and Logistic regression were employed to analyze the association between social determinants and the QoL .Results:There was no statistical significant difference in the QoL between the urban and the rural residents ( P>0 .05 ) .The elderly with higher education level and income or married tended to have higher overall QoL scoresand better performance of five dimensions of the QoL (P<0.05).Conclusion:More policies should be focused on the elderly with lower social determinants in both urban and rural areas in Beijing .
