Objectives:To study the effect of low carbohydrate formula's enteral nutrition in critically ill patients with hyperglycemia.Methods:52 patients were randomly divided into control group and study group.The control group was given Nutrison and the study group was given Diasip.Blood glucose,blood lipid,serum protein,PaCO_2 and PaO_2 were measured before and after therapy.Results:The fasting blood glucose was significantly increased in patients having received Nutrison and did need insulin treatment.The fluctuation of blood glucose was less in patients who had used Diasip and didn′t need insulin.The changes of serum protein were significant after therapy and were not significant between groups.The changes of serum lipid were significant after therapy and were not significant between groups.Conclusion:Diasip can control blood glucose and improve nutritional status and respiratory failure in critically ill patients with hyperglycemia.

The modern education requires creativity while the key to foster creativity is divergent thinking.To foster divergent thinking,we should reform the education system,improve the method,and change the evaluation method.Thus we can help students form comprehensive thinking capacity,shape question consciousness,get rid of conventionalism thinking type,foster divergent thinking,and improve the comprehensive quality.

Objective To evaluate the safety of epidural resiting and the incidence of postdural puncture headache following accidental dural puncture. HZ Methods Among 63 patients of ASA I-II undergoing lower abdominal or lower extremity surgery, forty-two with postdural puncture who had received epidural resiting were randomly assigned to patient controlled epidural analgesia (PCEA) ( n =21) or control treatment ( n =21). The remaining 21 patients who had successful epidural insertion received the routine PCEA. All patients after operation received 48-hours monitoring of BP, HR, RR and SpO_2. The analgesic effect of each treatment and the occurrence of headache were also assessed. Results All operations were uneventful under epidural anesthesia. A satisfactory level of analgesia was observed in patients who received PCEA. There was no statistically significant difference in pain control between patients who had had epidural resiting and who received PCEA and those who received routine PCEA. No respiratory inhibition was observed. The occurrence of headache in the epidural resiting group was 19% (4/21), compared to 57% (12/21) in the control group ( P

Objective:To evaluate the long-term safety of living kidney donors after nephrectomy.Methods:Twenty-six living donors of kidney were followed up for 2-8 years,with a mean of(4.27?2.11)years.The serum creatinine,blood pressure, proteinuria and psychological stress were observed in the donors during follow-up.Results..The serum creatinine had a significant increase after nephrectomy(P

Objective: To study the effect and mechanism of glutamine(Gln) on the intestinal barrier function in rats. Methods: Forty-five Sprague-Dawley rats were randomly divided into three groups(groupⅠ,groupⅡand groupⅢ) of fifteen animals each:.Rats of groupⅠ,groupⅡwere fed on normal diet and group Ⅲ was fed on 3% Gln-supplemented diet.The stress model was established in rats of groupⅡand Ⅲ.3 weeks later,the D-lactate,Gln levels in plasma and the contents of corticotropic releasing hormone(CRH),neurotensin(NT) in brain were measured.The morphology of small intestinal protein,DNA contents and its mucosa were observed. Results: Compared with control group,stress increased D-lactate level in plasma and reduced plasma glutamine level and the content of protein and DNA in small intestinal mucosa respectively.The small intestine demonstrated evident pathological characteristics under stress.Compared with stress group,D-lactate level in plasma was reduced and DNA content in small intestinal was increased in group Ⅲ.The CRH content in brain tissue was reduced and NT content in brain tissues was increased after Gln-supplemented.The pathological picture of small intestinal mucosa under stress was ameliorated after Gln-supplemented.Conclusion: The intestinal barrier function of rats may be protected after Gln-supplementation.Gln-derived neurotransmitters could alleviate the stressful damage of intestinal mucosa.

Convulsive status epilepticus (CSE) is an acute,life-threatening and neurologic emergency in children.The prognosis and the incidence of recurrent CSE depend upon the underlying etiology.It is very important to find related etiology and seek solution.The underlying etiology,classification and the diagnostic evaluation of the children with CSE will be outlined in this article.

Objective To explore the value of hepcidin measurement in differential diagnosis of iron deficiency anemia(IDA) and anemia of chronic diseases(ACD) .Methods Serum hepcidin was measured by using ELISA .Serum iron(SI) and total iron binding capacity(TIBC) were determined by using Ferro zine colorimetric method .Results Hepcidin expression increased in ACD group (P<0 .05) ,but decreased in IDA group(P<0 .05) .The area under the curve of ROC for hepcidin ,SI and TIBC were 0 .97 ,0 .66 and 0 .85 respectively .Conclusion Hepcidin is a simple and safe indicator in differential diagnosis of IDA and ACD ,and its diagnos-tic accuracy is better than SI and TIBC .

Intracranial pressure monitoring is a mainstay in the management of children with severe traumatic brain injury.The research issues on the intracranial pressure monitoring have become important for neurocritical care.This paper has reviewed the significance of intracranial pressure monitoring in children with severe traumatic brain injury.

Central nervous system demyelination in children include acute disseminated encephalomyelitis (ADEM),multiple sclerosis (MS),optic neuritis(ON),transverse myelitis(TM),neuromyelitis optica(NMO).Most of these conditions are thought to be caused by immune -mediated demyelination triggered by an infectious agent in a ge-netically susceptible host.There are certain differences,including clinical features and imaging features,for these condi-tions.With the possible exception of the NMO -IgG autoantibody found in NMO,there are no disease -specific biomar-kers for these conditions,making it difficult to distinguish among them at the time of the initial presentation.However, certain clinical features,laboratory results,and imaging findings can usually lead to the correct diagnosis.MS is to a large extent still a diagnosis of exclusion,and therefore requires intense investigation for other conditions that might present in a similar manner.
