AIM:To observe the protective effect of allitridi on hippocampal neuron of rats with cerebral ischemia-reperfusion (I/R) injury and to investigate its effects on P53 expression in hippocampus.METHODS: The global cerebral ischemia-reperfusion models were established by 4-vessel occlusion. Allitridi at doses of 10, 20 or 30 mg/kg was injected through rat’s tail vein, half dose at 30 min before brain ischemia and another half dose at 10 min after reperfusion were injected, respectively. The hippocampus of rat was removed 24 h after reperfusion. Toluidine blue staining was applied to estimate morphologic changes. Flow cytometry was used to evaluate neuronal apoptosis rate of hippocampus. Immunohistochemistry was used to observe the expression of P53 protein.RESULTS: Compared with sham group, survival neuronal density in I/R group was significantly depressed. The rate of neuronal apoptosis and the expression of P53 protein were significantly increased. Allitridi significantly increased the number of survival neurons in hippocampus compared to I/R group. Meanwhile, allitridi remarkably inhibited the rate of neuronal apoptosis and the expression of P53 protein.CONCLUSION: Allitridi has protective role against brain ischemia reperfusion injury. The mechanism may be involved in blocking P53 protein expression in hippocampus of rats with ischemia-reperfusion.

In order to determine the pathophysiologic significance of electrocardiographic ventricular hypertrophy in athletes (LVH ath), echocardiographic measurements of left ventricular mass (LVM) were performed on 50 LVH ath. and 50 non-LVH matched ath. They were members of National Teams of track and field, swimming, football and cycling, with an average age of 20.74?3.3 years. Anatomic validation of the method was used for calculation of LVM in this study. Comparisons of LVM were made between LVH ath. and non-LVH ath., and between non-LVH ath. and the untrained:LVM=1.04?[(LVID+PWT+IVST)~3-(LVID)~3]-14Results showed no significant difference of LVM between LVH ath. and non-LVH ath. while LVM of non-LVH ath. were considerably greater than that of the untrained (P

ObjectiveTo observe the effect of language rehabilitation training on stroke patients with complete aphasia.Methods10 stroke patients with complete aphasia were treated with language rehabilitation training.ResultsAfter training, scores of hearing, naming, reciting, reading, and writing of patients were significant higher than that before training (P<0.05—0.01).Conclusion Language rehabilitation training plays an active role in rehabilitation of stroke patients with complete aphasia.

We reported a case of polyglandular syndrome induced by programmed death-1(PD-1) inhibitors. The patient was a 51-years-old male with non-small cell lung cancer, treated with PD-1 inhibitor nivolumab/pembrolizumab because of postoperative subcarinal lymph node metastasis indicated by PET-CT. During 14 cycles of PD-1 inhibitor treatment, the patient successively developed primary hypothyroidism, and type 1 diabetes mellitus(T1DM). More than five months after the withdrawal of pembrolizumab, the patient experienced recurrentce. Laboratory examinations showed mild hyponatremia and hypopituitarism including ACTH and growth hormone(GH)/insulin-like growth factor-1(IGF-1) insufficiency. This is the first report of a patient diagnosed as polyglandular syndrome caused by PD-1 inhibitor. In particularly, the hypothyroidism and T1DM did not improve after drug withdrawal, while hypopituitarism was further aggravated. This case reminds us that we should pay more attention to the changes of endocrine function during and after the treatment of PD-1 inhibitor, so that we can make the correct diagnosis and take proper medical measures timely, to avoide missed diagnosis, and improper treatment.

Objective To investigate the application effect of comprehensive nursing care for severe hand-foot-mouth disease (HFMD) complicated with encephalitis. Methods A total of 70 children cases with severe HFMD complicated with encephalitis induced by enterovirus 71 infection admitted in our hospital from May 2012 to August 2013 were di-vided into observation group 35 cases and control group 35 cases. The control group was given symptomatic care, the observation group was given comprehensive nursing intervention. The fever and herpes subsided time, fatigue and limb shaking disappearance time, the average length of stay in hospital and the rate of complications were compared between two groups. Results The fever and herpes subsided time, fatigue and limb shaking disappearance time, the average hos-pitalization time in the observation group were shorter than the control group statistically (P<0.05 or P<0.01), hospital-ization time of the observation group was significantly shorter than the control group(P<0.01). The occurrence of compli-cations in the observation group were reduced in the observation group compared to the control group (P<0.01). Conclu-sion Comprehensive nursing intervention in children cases with severe type of HFMD complicated with encephalitis, combined with regular treatment, can reduce the incidence of complications and promote disease recovery.

Objective To probe into competence situation of the triage nurse in Children's Hospital, so as to provide the reference for the standardized management. Methods A total of 262 triage nurses in more than 20 Children's Hospital from all over the country. Results There were 255 women(97.3%,255/262);the age was(31.5 ± 3.8);among them,245 case were from the tertiary hospital and 17case from the two-levelhospital.Nearly 70.99%(186/262)of subjects had an undergraduate degree. Triage nurses(65.27%,171/262)had a working life of less than or equal to 5 years with the primary title (69.08%, 181/262). About half of the subjects (50.76%,133/262) did not receive professional training. A total of 173 subjects'workplace had a work experience requirements that was more than 2 years.After a comparison of different years of work experience in Two or three level children, the difference was statistically significant(P<0.05).Nearly 96.18%(252/262)of triage nurses agreed that they should be trained systematically and standardized.Nearly 92.75%(243/262)and 88.17%(231/262)agreed that the triage standards and National or provincial and municipal unified grading standards should be established, respectively. Conclusion It is essential that triage nurses should be trained and assessed systematically, Establishing a comprehensive, high quality and strong triage nursing team to meet the needs of practical work,which is an urgent problem for the hospital administrators.
