ObjectiveTo explore the relationship among self consistency and congruence,the feeling of inadequacy(FIS) and anxiety as well as the mediating effect of FIS between self consistency and congruence and anxiety.MethodsA total of 1164 students recruited from two medical colleges in Hebei province using cluster random sampling were investigated with scale for the feeling of inadequacy,self consistency and congruence scale and rating anxiety scale.ResultsThe relevance ratio of anxiety in Hebei medical colleges students was 42.7%.There were significant differences in the detection rate among genders(male:46.4%,female:40.5%),grade(freshman:38.9%,sophomore:41.0%,junior:47.5%)and family economic status(Preferably:38.5%,commonly:40.1%,badly:50.8%) in medical students(all P<0.05).There were no statistical significance for the incidence rates of students from different origins(P>0.05).Anxiety score was positively correlated with the score of self consistency and congruence(r=0.274,P<0.01),and was negatively correlated with the score of the feeling of inadequacy (r=-0.364,P<0.01).And the score of self consistency and congruence was negatively correlated with the score of feeling inadequacy(r=-0.335,P<0.01).Multiple stepwise regression analysis revealed that factors of the feeling of inadequacy and self consistency and congruence accounted for 35.6% of anxiety variance.The feeling of inadequacy played a mediating role in self consistency and congruence and anxiety.The mediating rate was 60.06%.ConclusionThe anxiety issue of medical students should be paid more attention.It is possible for the high level of feeling of inadequacy and low level of self consistency and congruence to increase the occurrence rate of anxiety.The feeling of inadequacy can strongly predict medical students'anxiety.

Objective To find out the trends and associated factors of birth defects in Guangdong province,and to provide the scientific evidences for setting the preventive strategies.Methods Retrospective description and trending analysis were conducted to analyze the birth defects surveillance data from 1996 to 2004 in Guangdong province.Results The total incidence of birth defects in Guangdong province from 1996 to 2003 was 134.4/10 000(7301/543 062),and increased to 212.1/10 000(2129/100 394)in 2004.Significant different birth defects rate was found between different maternal age(P

Objective To explore the effect of collaborative health education by both doctors and nurses on parturition?Methods One hundred and sixty primiparas at uterogestation undergoing analgesic parturition were assigned equally into the control and observation groups according to their admission sequence? The control group received routine nursing intervention and the observation group the collaborative health education by both doctors and nurses? The two groups were compared in terms of analgesic effect,vaginal delivery and post-partum hemorrhage? Result The rates of analgesic delivery and vaginal delivery in the observation group were significantly higher and the volume of postpartum hemorrhage was significantly smaller than those of the control group(all P < 0?05)?Conclusion The collaborative health education may be effective in alleviating mental stress of the preimiparas,enhancing the analgesic effect,increasing the rate of vaginal delivery and decreasing the volume of postpartum hemorrhage?

Objective To study the relationship among resilience,self feeling of inadequacy and alexithymia in depressive undergraduates,and to provide a theoretical basis for the prevention and intervention of depression among undergraduates.Methods 500 undergraduates of two universities in Hebei Province were collected by cluster sampling method.Beck depression scale,adolescent resilience scale,Toronto alexithymia scale and self feeling of inadequacy scale were applied to undergraduates.The survey results were analyzed statistically.Results The detection rate of depression was 28％(119/426) in undergraduates.Total score of Alexithymia Scale(69.99±9.43) was higher than the norm(65.70±7.98),and the difference was statistical significant (P＜0.05).The score of self feeling of inadequacy had a significant difference between male (149.88±28.00) and female(138.58±28.79) (P＜0.01).Neither gender nor grade had significant difference in depression,alexithymia and resilience(P＞0.05).Self feeling of inadequacy was positively correlated with alexithymia (P＜0.05).Resilience was negatively correlated with self feeling of inadequacy and alexithymia(P＜0.05).For the depressive undergraduates,self feeling of inadequacy served as a full mediator between the resilience and alexithymia,whereas for the non depression undergraduates it was a partial mediator.Conclusion Depression undergraduates have serious alexithymia,serious self feeling of inadequacy and poor resilience.Self feeling of inadequacy serves as a mediator between the resilience and alexithymia in depressive and non-depressive undergraduates.

Objective To explore the clinical significance of early biomarkers in neonatal asphyxia diagnosis with myocardial damage by detection of ischemia modified albumin in neonatal serum(IMA) and glycogen phosphorylase isoenzyme BB(GPBB) for screening sensitive markers with direct myocardial injury.Methods 166 neonates were selected in our hospital as the research object,in which 136 cases with myocardial injury dividend into the experimental group and 30 cases into the control group.The experimental group were divided into mild group and severe group according to the degree of asphyxia.All the children were tested for GPBB and IMA 1 h after admission.Results The levels of GPBB in neonatal asphyxia myocardial injury group and severe asphyxia group were significantly higher than those in the control group,the difference was statistically significant(P<0.05).The sensitivity of GPBB in diagnosis of asphyxia was higher than that of IMA,the difference was statistically significant(P<0.05).Conclusion The degree of asphyxia is closely related to serum IMA,GPBB level in neonatal asphyxia complicated with myocardial injury.The sensitivity and specificity of GPBB in diagnosis asphyxia is better than IMA in children complicated with myocardial damage.

Objective: To develop adriamycin liposome (AL) , adriamycin long circulating liposome (ALCL) and adriamycin long circulating temprerature-sensitive liposome ( ALTSL) and to study their anti-tumor effects on tumor-bearing mice. Methods: The antitumor activity was observed using the tumor weight as index. The life prolongation rate of mice was calculated according to the tumor-bearing mice survival time. The tissue distribution of adriamycin was determined by HPLC method. Tumor, heart, liver and kidney tissue of the tumor-bearing mice, were sliced and prepared to observe the tissue pathology differences. Results: Compared with free adriamycin, the anti-tumor effects of ALCL and ALTSL were remarkably increased. Their tumor growth inhibitory rates were 57. 8% and 67. 0% respectively. The study of pharmacoki-netics indicated that the adriamycin concentrations were remarkably higher in tumor tissue and blood,lower in heart and lung tissue of ALCL and ALTSL groups when compared with the free ADM group; The pathology slices indicated that tumor cells in the ALTSL group with hyperthermia were mostly destroyed; the cardiac muscle cells in the ALTSL group were similar to the normal cardiac muscle. Conclusion: ALCL and ALTSL remarkably increased the adriamycin concentration on the tumor site, significantly enhanced the anti-tumor effects, decreased the side-effects (such as cytotoxicity) when compared with free ADM, they also significantly prolonged the survival time of the tumor-bearing mice.
