Objective:To survey the awareness status of risk factors for gastric cancer and related factors among residents in Shijiazhuang city.Methods:From October to November 2020, residents aged>18 years were selected through convenience sampling from Xinhua District and Yuhua District in Shijiazhuang for a face-to-face questionnaire survey. The demographic characteristics and awareness levels of risk factors for gastric cancer among 1 490 subjects were analyzed. The multivariate linear regression model was applied to analyze the related factors.Results:There were 522 male participants (35.0%) and 968 female participants (65.0%). The mean knowledge score of risk factors of gastric carcinoma in the respondents was 5.0 (1.0, 11.0). There were 57.0% (849/1 490) of the participants who had a low knowledge level about risk factors of gastric cancer. The more highly recognized risk factors were irregular diet (47.4%, 706/1 490), consumption of pickled foods (45.2%, 674/1 490), consumption of smoked foods (45.0%, 671/1 490); the less-recognized risk factors included physical inactivity (14.8%, 221/1 490), male sex (17.3%, 258/1 490) and older age (19.5%, 291/1 490). Only 26.8% (400/1490) of the participants regarded H. pylori infection as a risk factor of gastric cancer. Univariate analysis showed that educational level ( Z=39.34), marital status ( Z=53.31), monthly income ( Z=11.82), family member or friend ever having stomach problem ( H=-2.98), and family history of gastric cancer ( H=-2.34) were significantly associated with the knowledge score of risk factors for gastric cancer ( P<0.05). Multivariate analysis showed that compared to participants with educational levels of primary school or below, those with educational level of junior high school ( β=0.27, P<0.001), high school ( β=0.23, P<0.001), or college ( β=0.16, P<0.001) had a higher levels of knowledge of risk factors for gastric cancer; compared to unmarried participants, awareness of risk factors was significantly better in those who were married ( β=0.16, P<0.001), divorced ( β=0.05, P=0.039), or widowed ( β=0.06, P=0.027); compared to participants with monthly income<3 000 yuan, the subjects with monthly income from 5 000 to 10 000 yuan ( β=0.07, P=0.020) had a higher knowledge score; compared to participants with no family history of gastric cancer, subjects with family history had higher knowledge level of risk factors for gastric cancer ( β=0.06, P=0.029). Conclusion:The knowledge levels of risk factors for gastric cancer are generally low among residents in Shijiazhuang city. Educational initiatives are required to improve the awareness of risk factors for gastric cancer, and interventions need to be implemented concurrently to change unhealthy behaviors among residents in Shijiazhuang city.

Objective:To investigate the status quo and training needs of general practitioner (GP) job-transfer training program in Hebei Province.Methods:An online survey with self-designed questionnaire was conducted on May 2019 through WeChat among 165 trainees in the General Practice Training Center of Hebei Province. A total of 165 questionnaires were distributed and 149 were valid with an effective rate of 90.3%. The contents of the questionnaire included the basic information of the trainees, the evaluation of the current training, and the needs of the GPs′ job-transfer training.Results:Among 149 participants, there were 131 (87.9%)from the secondary hospitals or above, 146(98.0%)with bachelor′s degree or above, and 128 (85.9%)with intermediate or above professional titles. The survey showed that 72.0%(67/93)thought the main reasons affecting participation in the training were busy work load and insufficient personnel, the main problems of training were too short training duration(45.2%, 42/93), the not focused training contents(38.7%, 36/93) and lack of practice(37.6%, 35/93). In the 149 trainees, 136(91.3%) thought that the most important contents should be standardized diagnosis and treatment of common diseases; 104(69.8%), 118(79.2%), 115(77.2%) and 98(65.8%) considered that the knowledge of prevention and health-protection, first aid, latest progress and chronic disease management were needed for training; 110(73.8%)and 80(53.7%)thought the mastery of clinical practice and basic theory were needed. And 57.7% (86/149)of the trainees believed that research training was needed, and there was significant difference in the demand for research training among participants from different work units and with different professional titles (χ 2=15.371,10.625,all P<0.05). The accepted training methods were case study(53.7%, 81/149) and practical work(37.6%, 56/149). For training duration, 43.6% (65/149) thought it should not exceed 6 months and 56.4% (84/149) preferred more than 1 year; there was a significant difference in demanded training duration among trainees from different work units, with different education background and professional titles (χ 2=16.225,6.243,25.966, all P<0.05). Conclusion:We need a multi-channel and multi-level training model to establish a better job-transfer training system for general practitioners, in order to meet different training needs and to improve the effectiveness of the training.

Objective: To understand the current situation of the social development between only children and firstborn of young age, so as to provide a reference for the promotion of the social development of young children. Methods: Stratified cluster sampling method was used to select 734 only children and firstborn children aged 3-9 in two kindergartens and two primary schools from grade 1 to grade 3 for questionnaire survey in Bengbu City. The content included the general information of children and their parents and the social assessment of children. Results: The rate of emotional symptoms in firstborn children(27.8%) was higher than those of only children (17.6%)( χ 2=9.45, P <0.01). The results of univariate analysis showed that the rate of hyperactivity and inattention in social development of both only children and firstborns decreased with the increase of family socioeconomic status ( P < 0.05 ). Multivariate Logistic regression analysis of only children showed that only children with high economic status had a lower risk of hyperactivity and inattention and had a higher risk of peer interaction( P <0.05). The prosocial behavior of girls was better than that of boys in the aspect of social development of only children and firstborn children( OR =1.70, 2.85, P <0.05). For only children, the occurrence risk of being difficult was lower when the primary caregiver was parents than grandparents( OR =1.63, P < 0.05 ). For firstborn children, the risk of being difficult in nuclear families was lower than that in third generation families( OR = 2.14 , P <0.05). Multivariate analysis of the only child showed that boys had higher risk of hyperactive attention and less prosocial behavior than girls ( OR =2.24, 1.70, P <0.05), and a lower risk of developing mood disorders than girls( OR =0.57, P <0.05). The social development of only children varied among different grades, and the risk of abnormal prosocial behavior was lower with the increase of grades ( P <0.05). Conclusion Higer family social status is positively associated with children s social development level. But parents with high economic status should also avoid too much material and spiritual doting. Parents should strengthen their own learning to enhance the level of socialized education, raising siblings equally, improve the quality of parent child relationship, and promote the all round development of children s socialization level.

Objective: To explore the interrelationships among fathers’ parenting effectiveness, urban children’s sociality and the acceptance of “second-born children” by children (including only children and “first-born children”), and to provide a reference for interventional measured for improving children’s acceptance rate of "second-bron children". Methods: Stratified cluster sampling method was used to select 3 to 9-year-old 778 only children and “first-born children” in two kindergartens and grades 1-3 of two primary schools in a city, and the children and their fathers were investigated with questionnaires survey regarding general information of both fathers and children, the acceptance degree of “second-born children”, the sociality of children and the parenting effectiveness of fathers. Results: Children in different grades had different acceptance levels of “second-born children” and the difference was statistically significant (F=2.89，P<0.05). Correlation analysis showed that the acceptance of “second-born children” was negatively correlated with the interaction between the only children and “first-born children”, and positively correlated with the prosocial behavior of the only children and “first-born children”, both of which are statistically significant (r=-0.10，0.10,P<0.01). Father’s role efficacy was negatively correlated with onlychildren and “first-born-children” peer interaction problems(r=-0.15), and positively correlated with prosocial behavior(r=0.32), both of which were statistically significant (P<0.01). The structural equation model of father’s parenting effectiveness, children’s sociality and acceptance of “second-born children” showed that low father’s parenting effectiveness could positively predict children’s peer communication problems and negatively predict children’s prosocial behavior, and thus children’s peer communication problems could negatively predict the acceptance degree of only children and “first-born children” to “second-born children”, and prosocial behaviors could positively predict the acceptance degree of “second-born children”. Conclusion Promoting father’s parenting efficiency can facilitate the social development of children and the acceptance of siblings.It’s recommended that fathers actively participate in specific parenting matters for the only child and "one child",and consciously improve parenting effectiveness.

Objective To survey the current status and training requirement of rural doctors in Hebei province.Methods A questionnaire survey was conducted among1 200 rural doctors selected from 11 cities of Hebei province by stratified sampling from October to December 2017.The self-designed questionnaire included general condition,job satisfaction,impact of medical reform policies,training needs of rural doctors.Results A total of 1 200 questionnaires were distributed and 1 170 valid ones were retrieved with a recovery rate of 97.5％.Among the 1 170 responders,there were 726 males(62.1％) and 444 females (37.9％);748 (63.9％) were aged more than 40 years;612 (52.3％) hold secondary school degree;826 (70.6％) had been working in the village for more than 10 years,and the overall job satisfaction rate was 30.8％ (360/1 170).Among all responders,73.8％ (864/1 170) worked in the standardized village clinics,and 72.0％ (842/1 170) were contracted with local residents as family doctors;52.8％ (618/1 170) responders believed that the reform policy improved the health care for villagers.In all responders,98％ (1 147/1 170)thought they needed training,93.6％ (1 095/1 170) had received training.The training contents they most needed werethe management of common diseases (904,77.3％),followed by medical humanities(650,55.6％)and first aid knowledge (492,42.1％).The influencing factors for training were lack of time,no energy (656,54.3％),lack of appropriate training forms (510,43.6％),economic reasons (476,40.3％) and so on.Conclusion The working status of rural doctors need to befurther improvedand the training need to be strengthened to increase their job satisfaction.

Objective: To assess the effect of health coaching on interventional effect in high-risk population of stroke. Methods: A baseline survey was conducted among 897 residents aged 40 years and above selected by cluster sampling method in a community of Shijiazhuang city from January 2016 to June 2016, and 178 subjects were identified as high risk population of stroke. The high-risk subjects were randomly divided into two groups: the control group (n=89) was given routine health education, while the intervention group (n=89) received health coaching based on motivational interview for 13 months. The behavioral risk factors and self-efficacy scores were compared between two groups before and after intervention. Results: There were no significant differences in behavioral risk factors between the two groups: for hypertension 72 vs. 74 cases (χ²=0.152, P=0.67), for hyperglycocemia 44 vs.48 cases (χ²=0.360, P=0.55), for dyslipidemia 62 vs. 60 cases (χ²=0.104, P=0.75), for smoking 35 vs.32 cases (χ²=0.215, P=0.64), for obesity 50 vs.52 cases (χ²=0.092, P=0.76), for lack of exercises 72 vs.70 cases (χ²=0.139, P=0.71), for atrial fibrillation 14 vs. 16 cases (χ²=0.160, P=0.19). And there was no significant difference in self-efficacy scores between the two groups [(5.3±1.2) vs. (5.6±2.0), t=0.997,P=0.32]. After intervention, there were significant differences between the two groups in behavioral risk factors: for hypertension 25 vs. 34 cases (χ²=19.984, P<0.05) , for hyperglycaemia 16 vs.32 cases (χ²=8.448, P<0.05) , for dyslipidemia 30 vs. 48 cases (χ²=13.216, P<0.05) , for smoking 20 vs.28 cases (χ²=7.583, P<0.05) , for obesity 18 vs.38 cases (χ²=14.158, P<0.05) , for lack of exercises 28 vs. 36 cases (χ²=10.235, P<0.01) , for atrial fibrillation 5 vs. 13 cases (χ²=6.451, P<0.05) . And the self-efficacy scores of intervention group were higher than those of control group[ (8.4±2.1) vs. (6.8±2.2), t=4.852, P<0.01]. Conclusion Health coaching based on motivational interview is beneficial to reduce risk factors and improve self-efficacy in high risk population of stroke, which is worthy of popularization.

Objective To evaluate the effect of "5As" (ask,advice,assess,assist,arrange) model based on the "two-in-one team" management (integrated hospital and community health service center management team) on the self-management behavior in stroke high-risk population.Method A stroke risk screening was conducted among 1 196 residents aged ≥40 years selected by cluster sampling in a community of Shijiazhuang city from March 2016 to March 2017,and 218 high-risk individuals were identified.The high risk individuals were randomly divided into intervention group and control group.The control group received routine health instruction,the intervention group was managed by "two-in-one team" with 5As model.Stroke prevention knowledge questionnaire and self-evaluation scale were applied for evaluation before and after intervention.Results Before intervention,scores of the stroke prevention knowledge and self-management behavior in the intervention group and the control group were (21.6 ±4.7) and (130.8 ± 6.4) points,(20.4±5.0) and (131.4 ±6.3) points,respectively (t =1.79,P =0.08;t =0.67,P =0.50).After intervention,the scores of prevention knowledge and self-management behavior in the intervention group were higher than those in the control group [(30.5 ± 5.1) vs.(21.7 ± 6.0) points,t =16.83,P=0.00;(158.3±19.0) vs.(135.6±20.0)points,t=7.85,P=0.00].Conclusion The 5As intervention model based on the two-in-one team management can improve stroke prevention knowledge and self-management behavior among stroke high-risk individuals in the community.

Objective To explore the effects of vinblastine on abcb4 tumor resistance gene expression in early development zebrafish and lay an important foundation for multi-drug resistant antineoplastic screening in zebrafish model.Methods Zebrafish embryos of 0.5~1.5 hours post-fertilization were exposured to different concentrations of vinblastine, and then calculated the IC50 of vinblastine.Zebrafish embryos of 0.5~1.5 hours post-fertilization were treated with different concentrations of vinblastine and embryo culture medium respectively, and then observed zebrafish embryo development in 24~120 hours post-fertilization and recorded the number of death, hatch and malformation.Evaluating the impact of vinblastine on abcb4 gene expression in zebrafish with quantitative real-time PCR and whole-mount in situ hybridization by collecting zebrafish embryos exposed to different concentrationsof vinblastine.Results Vinblastine IC50 in zebrafish embryos was 3.08 μmol/L.The mRNA level of abcb4 gene in vinblastine treated embryos was significantly increased compared to blank control group.Moreover, abcb4 gene positive hybridization signals were found in the small intestine of zebrafish embryos after 120 hours post-fertilization and also found in the brain and heart of zebrafish embryos by the method of whole-mount in situ hybridization.Conclusions Vinblastine can significantly increase the expression level of abcb4 tumor resistancegene in early development zebrafish embryos, which indicates that zebrafish can be used as a tumor resistant drug screening model.

Objective To investigate the effects of gefitinib on early embryonic development and expression of abcb4 tumor resistance genes in zebrafish.Methods Zebrafish were adopted as experimental animals and divided into gefitinib group,mixture of doxorubicin and gefitinib group and blank group.Zebrafish embryos of 0.5-1.5 hours after fertilization(0.5-1.5 hpf) were exposed to different concentrations of gefitinib,and then embryo development of zebrafish in 24-120 hpf was observed and the number of death,hatch and malformation was recorded.The embryo mortality was calculated under different concentrations of gefitinib at different time points,and the numerical value of IC50 was calculated;Hatching rates of zebrafish embryo in 48 hpf and 72 hpf and malformation rates of zebrafish embryo in 120 hpf were calculated.The zebrafish embryos exposed to different concentrations of gefitinib in different groups were collected,and the expressionof abcb4 gene in zebrafish embryos was detected by real-time quantitative PCR.Results Gefitinib IC50 in zebrafish embryos was 16.18 μmol/L.Compared with the control group,higher dosage (20 μmol/L) of gefitinib in other two groups significantly decreased hatching rates of embryos,and had obvious embryonic lethal effects and teratogenic effects.Moreover,the mRNA levels of the abcb4 gene in the zebrafish embryos of gefitinib group were not significantly changed,whereas the mRNA levels of the abcb4 gene in mixture of doxorubicin and gefitinib group were significantly different(P＜0.05).Conclusion Gefitinib has no significant effects on the expression of abcb4 tumor resistance gene in early development of zebrafish embryos(P＞0.05),but it can reverse the drug resistant effects of doxorubicin,suggesting that zebrafish can construct tumor resistance model.
