Objective To investigate the effects of early pregnancy exposure to hazardous indoor air pollutants due to interior decoration and hyperthermia on neurobehavioral development of postnatal rats.Methods Twenty-two pregnant rats were randomly divided into 4 groups.Each group was placed in pollutants cabinet,hyperthermia cabinet,hyperthermia+pollutants cabinet and empty cabinet respectively for 2 h per day for 10 d since their pregnancy.The weight and neurobehavioral development of postnatal rats were observed at different time points.The number of apoptotic and dead neurons in the CA1 region of hippocampus was observed in postnatal rats.The expression of the NR1 subunit of NMDA receptor of hippocampal neurons was also detected.Results Indoor pollutants and hyperthermia could accelerate apoptosis and necrosis of hippocampal neurons in CA1 region of postnatal rats and increase the expression of NR1 subunit of NMDA receptor.Furthermore,hazardous indoor pollutants and hyperthermia could induce remarkable influences on postnatal rats’ neurobehavioral development,learning and memory capability.Indoor pollutants combined with hyperthermia aggravated these effects.Conclusion Exposure to environment of the hazardous indoor pollutants especially combined with hyperthermia during early pregnancy has remarkable influences on the nervous system of postnatal rats.

Objective To observe the effects of chemical compounds exposure and hyperthermal environment to pregnant rats on the hippocampus neuronal morphology and neurobehavioral development of their offsprings. MethodsPregnant rats were divided into 4 groups randomly: the control group; chemical compounds exposure group, chemical compounds combined hyperthermal exposure group and hyperthermal group. The control group was living in normal condition; the chemical compounds exposure group in a cabin with benzene (20.26?0.80) mg/m3, toluene (39.66?4.23) mg/m3, dimethylbenzene (42.40?2.85) mg/m3, and formaldehyde (23.13?1.30) mg/m3; the hyperthermal group was kept in an atmosphere of 38.5 ℃; and the combined group was exposed to the chemical compounds and high temperature at the same time. All animals were treated respectively 2 h per day for 10 d since their pregnancy. Their offspring were lived in normal condition. The development of brain and changes of hippocampus neuronal morphology were observed just or 1 month after born. The primary reflex activity of new-born rats was also examined. ResultsThere was no abnormality in the brain of new born rats from 4 groups. In the chemical compounds exposure and the combined exposure groups, the number of degeneration and necrosis neurons in CA1 region of hippocampus were significantly more than those in control and hyperthermal groups (P

Objective To explore the feasibility of somatosensory evoked potentials (SEP) evaluating Tourette syndrome, based on the theory of SEP evaluating sensory-motor cortical function. Methods 33 cases of Tourette syndrome in our hospital from March 2014 to April 2015 were as the experiment group and 30 healthy participants were as the normal control group. Both groups were evaluated with Yale Global Tic Severity Scale (YGTSS) and SEP. Results There was no significant difference in N20 leak latency and leak-leak amplitude of SEP between 2 groups (P>0.05). The P22 leak latency prolonged (t=2.356, P<0.05) and the leak-leak amplitude decreased (t=2.507, P<0.05) in the experiment group compared with the normal control group. The YGTSS score was higher in the experiment group than in the normal control group (t=3.012, P<0.01). The P22 leak latency was positively (r=0.402, P<0.001), and the P22 leak-leak amplitude was negatively (r=-0.180, P<0.001) correlated with YGTSS score. Conclusion Children with Tourette syndrome are disordered in inhibiting sensory or mo-tor impulse through cortex-striatum-thalamus-cortex regulation circuit. SEP is considered as the objective indicator of patients with Tourette syndrome.

Objective To follow up the long-term prognosis of acute kidney injury (AKI) patients with normal basic renal function,and to further identify the clinical features as well as risk factors associated with the prognosis of AKI patients.Methods Clinical date of 166 patients who occurred AKI episode during hospitalization from Jan 1 2011 to Dec 31 2014 in The First Affiliated Hospital of Fujian Medical University were retrospectively analyzed.All these patients had normal basic renal function and had follow-up of more than two years after discharge.According to their renal function after two years,patients were divided into recover and non-recover group.The clinical features and risk factors associated with the prognosis of AKI patients were identified using multivariate logistic regression,and the proportion of renal function progression was calculated during follow-up period.Results One hundred and sixty-six patients were enrolled in this observational study,including 114 male,52 female with an average age of 58.1± 16.6.Eighty-seven patients were AKI stage 1,39 AKI stage 2,and 40 AKI stage 3.Thirty-seven patients were caused by pre-renal factors,113 patients by renal causes and 16 patients by post-renal causes.Renal function when discharged (P=0.002,OR=2.980) and infection (P=0.003,OR=2.786) were the risk factors of failing to restore after two years.Eighty-four patients' renal function returned to normal when discharged,but the number of patients whose renal function progressed to CKD 3 stage and even worse 1 year and two years later were 12 (14.3％) and 20 (23.8％) respectively.Fifty-four patients were diagnosed as partial recovery and 28 patients as non-recovery when discharged.One year later 22 (40.7％) and 12 (42.9％) patients' renal function progressed to CKD 3 stage and more,while those numbers became 28 (51.9％) and 16 (57.1％) two years later.Conclusions The risk factors of AKI long-term outcome include unrecovered renal function when discharged and infection.After AKI episode,even with fully recovered renal function,patients are still possible to progress to CKD,highlighting the importance of follow-up observation.

OBJECTIVE: To explore the relationship among perceived organizational support,job burnout and depressive tendency in nursing staffs. METHODS: A total of 807 nurses from 7 municipal hospitals in Zhengzhou City,Henan Province were selected as the study subjects by multi-stage cluster random sampling method. The questionnaires of Perceived Organizational Support,Maslach Burnout Inventory-General Survey and Center for Epidemiological Survey-Depression Scale were used to conduct the survey. RESULTS: The total scores of perceived organizational support and job burnout were( 69. 3 ± 18. 5) and( 36. 3 ± 13. 7) respectively. The median of the total score of depression tendency was 17. 00. The total score of nurses' perceived organizational support was negatively correlated with the total scores of job burnout and depression tendency( P < 0. 01). The total score of job burnout was positively correlated with the total score of depression tendency( P < 0. 01). The degree of explanations for the change of perceived organizational support and job burnout on depression tendency were 9. 1% and 13. 1%,respectively. CONCLUSION: Perceived organizational support and job burnout play important roles in predicting depression tendency. Job burnout plays a mediating role in the relationship between perceived organizational support and depression tendency.
