AIM: To evaluate the application and effect of questionnaire based on professional knowledge method combined with problem - based learning ( PBL ) in ophthalmology short-term teaching.
METHODS: Ninety non ophthalmic students of Beijing Hospital of Traditional Chinese Medicine from January to August 2015 were randomly divided into observation group (45 students) and control group (45 students). Observation group: using questionnaire based on professional knowledge method combined with PBL teaching method; the control group: using traditional teaching method.
RESULTS: The survey results showed that: non ophthalmic students were unfamiliar with eye diseases knowledge; there was no significant difference in the clinical operation examination between the 2 groups (P>0. 05 ). There were significant differences in the eye disease knowledge, eye disease knowledge related to their own major and the total score between the 2 groups (P< 0. 05), especially students in the observation group had higher scores of eye disease knowledge related to their own major. There was no significant difference in the rate of improvement of learning pressure between the 2 groups (P> 0. 05), the differences of improvement rate on other problems between 2 groups was statistically significant ( P < 0. 05 ), and the improvement rate was higher in the observation group.
CONCLUSION: Questionnaire based on professional knowledge combined with PBL teaching method can effectively improve the learning effect in ophthalmology teaching.

Objective To investigate the efficacy of amplitude-integrated electroencephalographic (aEEG)in evaluating the maturation of cerebral function in preterm infants.Methods Ninety one neurologically normal and clinically stable preterm infants admitted to neonatal intensive care unit were studied prospectively by using aEEG.Background of aEEG activity patterns,presence of sleep-wake cycles,and the lower and higher border were analyzed.Results 112 aEEG were analyzed.The sleep-wake cycle and the continuity became more mature with PMA increased.The lower border were increased and the higher border were decreased with PMA increased(r =0.982,P ＜ 0.01 ; r =-0.964,P＜0.01).Conclusion In preterm infants,aEEG is a useful tool to evaluate the maturation of cerebral function.

Objective To investigate the present situation and outcome of cardiopulmonary resuscitation (CPR) for pediatric in-hospital cardiopulmonary arrest and to analyze the prognostic risk factors.Methods Data were collected from October 2008 till October 2011 using Ustein style.Patients older than 28 days who received CPR were evaluated.Returning of spontaneous circulation(ROSC) more than 24 hours was the primary outcome.Neurological outcome was assessed by pediatric cerebral performance categories half year after discharge.Results Of the 36 patients,15 (41.7％) achieved sustained ROSC.Seven (19.4％) patients survived to discharge.Single factor analysis indicated that the beginning heart rhythm,defibrillation and original disease were significantly different between the two groups(P ＜0.05).The beginning heart rote of the patient in ROSC ＞ 24 h group was mostly sinus bradycardia.Patients who need defibrillation had bad prognosis.Patients with heart disease had a lower rate of ROSC ＞ 24 h.At half year follow-up study,4 patients had 1 or 2 score,1 patient had 4 and 1 had 5 score in the pediatric cerebral performance categories scales.Condusion The successful rate of CPR in our hospital was the same as that in developed country.The beginning heart rhythm,defibrillation and original disease were associated with the outcome.Most of the patients who survived to discharge had a good neurological outcome.

Objective To explore the association between human papilloma virus(HPV)infection and antisperm antibodies(As-Ab)in male infertile patients in Xinjiang area.Methods A total of 127 cases of infertile male patients were selected as experimental group,other 130 cases of normal male were enrolled in the control group.HPV sperm infection was detected by using reverse dot blot hybridization kit.The levels of AsAbs in semen specimen were measured by using the enzyme-linked immunosorbent assay (ELISA).Results The infection rate of male infertile patients(67.7%)was higher than that of normal male(1 6.2%),with signifi-cant differences(P <0.05).The positive rate of AsAb of male infertile patients with HPV infection(38.4%)was higher than that of male infertile patients without HPV infection(1 7.1%),with significant differences(P <0.05).Compared with male infertile pa-tients without HPV infection,the percentages of sperm motility and grade (a+b)sperm motility were decreased in male infertile pa-tients with HPV infection,wihile the sperm malformation rate was increased in male infertile patients with HPV infection,with sig-nificant differences(P <0.05).Conclusion The HPV infection rate of male infertile patients is relatively high in this area.HPV sperm infection could be associated with AsAb that may further reduce male fertility.

Liver innate immunity plays an important role in the defense against pathogen invasion.The mechanisms of liver innate immunity for defending against pathogen invasion are reviewed,including the special anatomical and physiological characteristics of the liver,the fea-tures of innate immune cells in the liver (liver-settled cells and cells raised from blood circulation)and their function and relationship with each other in pathogen invasion,the process of pathogen identification and effect of liver innate immune cells,and the mechanism of liver immune injury and immune tolerance.Given current research on innate immune cells and innate immune molecules in the liver,further stud-ies should be conducted to understand the connection and difference between liver innate immunity and systemic immunity,thus promoting the diagnosis and treatment of liver diseases and deeper research.

OBJECTIVE:To provide a new management mode for the rational use and standardized management of narcotics in hospital.METHODS:The fingerprint management system of narcotics was build up and applied.RESULTS:The fingerprint management system of narcotics could accurately help identify patients' identity and provide effective supervision for using narcotics.CONCLUSION:The fingerprint management system of narcotics can replace the current management mode for it makes up the shortage of the traditional management system.

Objective To investigate the effects of focal mild hypothermia on apoptotic neurons and the expression of glutamate transporter(GLT-1)and metabotropic glutamate receptor(mGluR2/3)after cerebral ischemia in rats.Methods Eighty-eight adult rats were randomly divided into mild hypothermia group,normothermia group and control group.Unilateral permanent middle cerebral artery occlusion(pMCAO)was induced.In mild hypothermia group,the brain temperature of occlusive side was decreased and maintained for 3 h at(33?0.5)℃ with Sticking Focal Mild Hypothermia Instrument.The body temperature of normothermia group was maintained at(37?0.5)℃.3 h,6 h,12 h,24 h,3 d,7 d after cerebral ischemia,the expression of GLT-1 and mGluR2/3 around infarction cortex were determined by Western Blot.6 h,24 h,3 d,7 d after cerebral ischemia,TUNEL method was performed to label neuronal apoptosis.Results 24 h,3 d after cerebral ischemia of mild hypothermia group,24 h,3 d,7 d after cerebral ischemia of normothermia group,the apoptotic neurons around infarction core markedly increased comparing with 6 h after cerebral ischemia(all P

AIM:To evaluate the poor vision condition and analyze the myopia etiological factor in primary school He'xi district of Sanya.
METHODS: A cohort of 1 218 subjects were recruited randomly from grade 1~6 of two primary schools. Visual activity test, dioptroscopy and risk factor questionnaire were evaluated.
RESULTS: The prevalence of poor vision was 29. 55%. The incidence of myopia increased with grade, and was significantly higher in girls than that in boys. The outdoor activity time of myopic pupil ( 7. 25 ± 5. 35h/wk ) was significantly lower than emmetropic pupil (11. 86±6. 65h/wk) ( P < 0. 05 ). The usage of electronic product ( TV, computater and cell phone) time of myopic pupil (13. 36±8. 35h/wk) was significantly higher than emmetropic pupil (7. 75±5. 83h/wk) (P<0. 05).
CONCLUSION: The increase of myopia incidence is closely related with sparing outdoor activity and excess usage of electronic product.
