Objectives To study a special pattern of electroencephalogram (EEG),regional attenuation without Delta in massive cerebral ischemic infraction and evaluate its clinical value.Methods All the 47 cases diagnosed as massive cerebral infraction were continuously observed and evaluated in the period of 2004 to 2006 for EEG,short-latency somatosensory evoked potential (SLSEP).Glasgow coma scale (GCS) and the National Institutes of Health Stroke Scale (NIHSS) were also rated.EEG monitoring was performed every 1 to 3 day,but at least one time for patient with deteriorated condition.The outcome was evaluated with Glasgow outcome scale (GOS).Results 47 cases were performed 70 times of EEG all together,among whom 32 cases (68.1%) showed RAWOD in EEG.The positive rate of RAWOD was 76.9% within 24 hours of onset,but it was 28.6% in CT in the same time.The GCS and NIHSS of two groups had significant differences (P

As we known,serum creatinine(Scr),serum urea nitrogen(SUN) and creatinine clearance rate(Ccr),the most established marker of renal function,are affected by age,gender,muscle mass or nutritional status.Scr determines the glomerular filtration rate(GFR) improperly.Serum Cystatin C(sCys C) is freely filtered at the glomerulus and then resorbed and fully catabolised by proximal renal tubules,ma-king it an ideal marker of GFR.It is not affected by gender,muscle mass or malignancy,its production rate is usually constant and its plasma concentration therefore is dependent only on GFR.sCys C has been demonstrated to be more accurate and sensitive than Scr in the detection of early renal impairment and in specific populations may allow for early detection of renal disease.The aim is to discuss the advantages and limitations of sCys C and of established GFR methods.

Objective To explore the application of Orem self-nursing theory on patients under nursing after uterine neck cancer operation.Methods 90 patients after uterine neck cancer operation were randomly divided into two groups.45 cases as observation group and 45 cases as control group.The patients in the control group use normal nursing and common health education after uterine neck cancer operatlon;the observation group applies Orem selfnursing theory to assess the patients' nursing ability and uses different nursing system and personality health education knowledge for the promotion to let the patients to participate in the nursing activity based on the situation.Results Activity time after out of bed,gas releasing time of anus in observation group are evidently earlier than that of the control group,also have vomit and abdominal distension digestion system symptom decrease after the patients operation;the urethra infection and retention of urine rate are significantly lower than that of the control group and the difference is remarkable(P < 0.05 ).Conclusion The Orem self-nursing theory are used in nursing of patients after uterine neck cancer operation to facilitate the recovery of health after patients operation so as to relieve the burden of family and society and improve quality of living of patients.

Objective To investigate an accurate,reliable and objective method to evaluate persistent vegetative state at bedside.Methods The brain function of 34 cases with persistent vegetative state as a result of acute brain injury was evaluated,involving clinical examinations and neuroelectrophysiological evaluations(EEG,BAEP,SLSEP).Results The most common cause of brain damage was anoxic encephalopathy(30/34,88.2%).The patients were in mild,moderate or deep coma with complete or partial existence of brainstem reflection,activities distributed by cerebral nerves,voluntary extremity activities,spinal cord reflection and automatic spinal cord reflection as well as partial existence of pathologic reflection.According to the Young Criteria of EEG,64.5%(20/31)and 29.0%(9/31)of the cases were in grade Ⅰ and Ⅵ respectively,6.5%(2/31)were in grade Ⅲ and Ⅳ.According to the Cant Criteria of evoked potential,34.8%(8/23),21.7%(5/23)and 43.5%(10/23)of the cases were in gradeⅠ,Ⅱ and Ⅲ of brainstem auditory evoked potential,respectively.43.5%(10/23),4.4%(12/23) and 52.2%(12/23)were in grade Ⅰ,Ⅱ and Ⅲ of short-latency somatosensory evoked potential respectively.29.4%(10/34)of 34 cases died,and 11.8%(4/34)resuscitated during 35—90 days. Conclusion Combination of multiple neuroelectrophysiological tests was an accurate,reliable and objective approach to evaluate the brain function of patients with persistent vegetative state,which provides evidence for decision-making in agrypnotic therapy.

Expressed emotion was the describing term about the guardian of patients' emotiveness tendency to patients,which reflected attitude,tolerance degree and the coping way in crisis.It was a robust predictor of relapse of schizophrenia.Studies showed that the family intervention for the high expressed emotion guardian of patients could effectively reduce the disease relapse.By summarizing the expressed emotion's concept,assessment tools,influence factors,family interventions,the paper aimed to innovate perfect interventions and promote the patients recovery.

Objective To explore the effects of prenatal exposure to lead on learning and memory of rats' offspring. Methods The pregnant rats were randomly divided into 4 groups provided with double evaporated water, 50, 100 and 200 mg/L lead acetate solution via drinking water respectively. The lead-exposure period for exposure groups was limited from the 1st day after pregnancy to the 20th day when the offspring began to be weaned. For learning ability 20-day old offspring were tested by water maze. For active learning and memory ability, the 20-day old, 40-day old and 60-day old offspring were tested by Y maze. Results The frequency of the mistakes in water maze made by offspring increased with the increase of the prenatal lead-exposure doses of their mothers and showed significantly higher levels in 100 and 200 mg/L groups compared with that of control group (P0.05). But the qualified rates of 0-min and 24-h escape for 100 and 200 mg/L groups showed sigificantly lower levels compared with that of control group when they were 60-day old (P

Objective To explore the effect of adenovirus-mediated bcl-2 transfer on the regeneration and repair of peripheral nerves in rats. Methods The sciatic nerve-transected model was selected and sutured end to end with epineurium. Then, adenovirus/sense-B-lymphoma/leukemia-2 (Ad/s-bcl-2), adenovirus/anti-sense-B-lymphoma/leukemia-2 (Ad/as-bcl-2), adenovirus/?-galactosidase (Ad/LacZ) and normal saline (NS) were injected into the sciatic nerve 0.5 cm away from the sutured point respectively. The rats were perfused with 4% paraformaldehyde at the 48th hour, 7th, 15th and 30th days respectively after operation. The spinal cords L 4-6 were harvested, frozen sectioned and given x-gal staining, bcl-2 in situ hybrid and immunohistochemical staining and GAP-43 immunohistochemical staining. The postoperative functional recovery of the rear limbs of rats was dynamically observed by using sciatic nerve functional index (SFI). Results The GAP-43 expression in the motor neurons of anterior horn of spinal cord in group Ad/s-bcl-2 was higher than that in other groups (P0.05). Conclusions Gene transfer of bcl-2 can promote regeneration and functional recovery of the peripheral nerves following sciatic nerve injury.
