Objective To analyze the clinical features and prognosis of hyperglycemia and the relationship between the blood glucose level and the severity of disease in critically ill children.Methods A total of 349 critically ill children admitted in Pediatric Intensive Care Unit (PICU) from November 2009 to April 2010 were restrospectively analyzed.According to the levels of venous blood glucose within 24 h after admission,they were divided into very high level group (blood glucose ≥11.1 mmol/L,n =67 ),slightly high level group (blood glucose 6.3-11.1 mmol/L,n =134) and normal level group (blood glucose ≤6.3mmol/L,n =148).Blood glucose levels were measured within 24 hours,3 days and 7 days after admission.Electrolytes,inflammatory markers,cardiac enzymes,liver and kidney function as well as other biomarkers related to the severity and the prognosis of the patients were recorded after admission.The categorical variables were analyzed with Chi -squared test,the continuous variables were analyzed with t-test,F-test,U-test andH-test,and the correlation analysis was calculated by using Pearson Coefficients. Results In the very high level group,slightly high level group and normal level group,the average blood glucose levels were 16.98 ±7.08 mmol/L,8.25 ± 1.40 mmol/L and 4.89 ± 0.98 mmol/L ( P ＜ 0.01 ),respectively;and the Pediatric Critical Ⅲ Scores at admission were 81.22 ± 8.25,86.71 ± 6.40 and 86.15 ± 6.99 ( P ＜0.01 ),respectively,and the incidences of sepsis or septic shock were 55.23％,30.59％ and 14.18％,respectively (P ＜0.01 ),and the incidences of MODS were 46.26％,22.39％ and 16.23％,respectively (P ＜0.01 ).The blood glucose levels of patients with one organ failure and two organ failure were 8.27 ± 3.75 mmol/L and 8.88 ± 5.42 mmol/L,respectively ( P ＜ 0.05 ).The blood glucose levels of patients with two organ failure and multiple organ failure were 8.88 ± 5.42 mmol/L and 13.09 ± 8.23 mmol/L,respectively (P＜0.01).The mortality rates of three groups were 47.76％,14.93％ and 10.13％ (P ＜0.01 ),and the blood glucose levels at admission in survival group and death group were 7.57 ±4.11 mmol/L and 12.46 ± 8.17 mmol/L ( P ＜ 0.01 ).Conclusions Patients with hyperglycemia are often found in the PICU.It not only partially reflects the severity of the disease,but also serves as an important indicator for the prognosis.The blood glucose level is positively correlated to the number of compromised organs and the severity of the disease.Dynamic monitoring of blood glucose may be essential for controlling the symptoms and prediction of prognosis.

Objective To analyze the clinical features of the hyperamylasemia in critically ill children and investigate the related risk factors in order to provide the basis for prevention and treatment. Methods A total of 1036 critically ill children admitted in pediatric intensive care unit (PICU)from April,2011 to Oct,2012 were studied.They were divided into the high amylase group (n=82)and the normal group (n=954).According to the outcomes,the high amylase group was divided into survival group (n=61 ) and death group (n =21 ).The related risk factors of the occurrence and outcome of hyperamylasemia were analyzed by univariate and multivariate Logistic regression.Results There were statistically significant differences in rates of coagulation disorders, convulsions, disturbance of consciousness,pediatric critical illness score (PCIS)≤80,multiple organ dysfunction (MODS)≥3, sepsis,shock,and lactic acid (LA),procalcitonin (PCT),blood glucose (BG)between the high amylase group and the normal group (P<0.05 ).The differences in the rates of coagulation disorders,convulsions, mechanical ventilation,PCIS≤80,MODS≥3,and LA,PCT,oxygenation index,albumin,C-peptide,BG were statistically significant between the survival group and the death group (P <0.05 ).Multivariate Logistic regression analysis showed that the risk factors of the hyperamylasemia's occurrence were LA,PCT, BG,PCIS<80,MODS>3.Adjusted ORs confidence intervals of them were 1.662 (1.236-2.234),1.042 (1.025-1.060),1.612 (1.411-1.843),3.219 (1.311-7.905),3.411 (1.370-8.494),respectively. The hyperamylasemia's prognostic risk factors were PCT,C-peptide,PCIS ≤80,MODS >3,shock. Adjusted ORs confidence intervals of them were 1.066(1.021-1.113),1.437(1.017 ~2.030),16.137 (1.876-138.836),10.437(1.528-71.925),20.928(1.938-226.009),respectively.Conclusions The severity of the disease,the levels of LA,PCT,BG in critically ill children were positively correlated to the occurrence of hyperamylasemia.The severity of the disease,the incidence of organ failures,the levels of PCT,C-peptide combined shock in children with hyperamylasemia were positively correlated to the prognosis of hyperamylasemia.

Objective To investigate the serum procalcitonin (PCT) levels in sepsis caused by the bacteria,virus and mycoplasma and explore the role of PCT in etiology diagnosis of sepsis in children.Methods Three hundreds and thirty critically ill children with sepsis caused by bacteria,virus and mycoplasma admitted in PICU of Hunan Children' s Hospital from Feb 1,2011 to Sep 1,2012 were reviewed and analyzed.The PCT levels were measured at admission and day 3.The differences in accidence of sepsis caused by bacteria,viruses and mycoplasma according to different serum PCT levels were analyzed.The differences of PCT levels at admission and day 3 in sepsic children caused by bacteria,viruses and mycoplasma were analyzed.Results The level of serum PCT in sepsis caused by bacterial infection were distinctly increased,caused by virus and mycoplasma infections was not obvious but the increases of serum PCT [0.71 (8.14)ng/ml,0.15 (1.68) ng/ml,0.28 (1.89) ng/ml].According to various PCT levels(0.05 ～ ng/ml,0.5 ～ng/ml,2 ～ ng/ml,10 ～ 300 ng/ml),the differences of accidence of sepsis caused by bacteria,virus and mycoplasma were also statistically significant(x2 =84.50,P ＜ 0.01).The PCT level of septic children caused by bacterial infection in day 3 was significantly decreased compared with that at admission [0.32 (5.68) ng/ml vs 0.71 (8.14) ng/ml] (U =19.34,P ＜0.05).Conclusion PCT plays a certain role in etiology diagnosis of sepsis in children.The increased PCT levels which can be reduced by anti-inflammatory treatment indicate the likelihood of bacterial infection and sepsis.The increase of PCT induced by viral and mycoplasma infections is not obvious,but bacterial infection can not be completely ruled out.

Objective To investigate the clinical performance of fiber post restorations in elderly patients with residual root and crown and to analyze the factors affecting the clinical success rate.Methods A total of 66 elderly patients requiring post restoration were selected.They were randomly divided into two groups:the observation group (n=33,restored with fiber post-resin cores) and the control group (n=33,restored with cast metal post-cores).All patients were rechecked 1 year and 2years after the restoration.The clinical efficacy and the failure types were recorded.The differences in clinical performance between the 2 groups were compared by using Fisher's exact test.Results The differences in the gingival index and periodontal index in the 2 groups between the experimental teeth and the control teeth were zero.There were no significant differences in dental morphology,root canal treatment failure,tooth color matching and marginal coloration between the 2 groups (all P＞0.05).1 case with post debonding and 1 case with fiber post fracture were found in the observation group and 1 case with marginal coloration was found in control group.There was no significant difference in clinical success rate between the 2 groups (93.94％ vs.96.97％,P＞0.05).Conclusions The clinical success rate in fiber post-resin core restoration is the same as in cast metal post-cores restoration in elderly patients.

With the continuous improvement of people's living standard, more and more people are in pre-diabetes state. Pre-diabetes is the key to the development of diabetes, and early intervention can reduce the incidence of diabetes, and prevent transforming pre-diabetes to diabetes in order to maintain the health status of the patient. By retrieving the Chinese Biomedical Literature Database of nearly five years on pre-diabetes intervention literature, it was found that traditional Chinese medicine interventions in pre-diabetes have a relatively new understanding. Through the traditional Chinese medicine, acupuncture, acupoint massage, and combine traditional Chinese and western medicine, medicinal food, eight brocade etc intervention therapy in patients with pre-diabetes, the occurrence and development of diabetes and its complications can be effectively prevented.

Objective To study the impact of Xingnaojing (XNJ) injection (a preparation of Chinese herb medicine) on the permeability of blood-brain barrier and Caveolin-1 in cortex of brain after global ischemia-reperfusion.Methods Modified Pulsinelli method for four-vessel occlusion was employed to establish the global ischemia reperfusion model in rats.Male Wistar rats were randomly (random number) divided into three groups,namely sham group,model group and XNJ group.Each group was observed at 24 h,48 h and 72 h after ischemia reperfusion.The water content of brain tissue was determined by dry/wet weight ratio,while the Evans blue (EB) concentration in brain tissue was detected by spectrophotometer.Western blot was used to detect caveolin-1 level in the cerebral cortex.Results The water contents of brain tissue in model group and XNJ group were significantly higher than that in sham group 24 hour after ischemia-reperfusion (P ＜ 0.05).But at 48 h and 72 h after ischemia-reperfusion,the brain water content in model group was significantly higher than that in XNJ group and sham group (P ＜ 0.05).The EB concentrations in brain tissue in model group and XNJ group were higher than that in sham group 24 h after ischemia-reperfusion (P ＜ 0.05).EB levels in sham group and XNJ group were significantly lower than that in model group 48 h and 72 h after ischemia-reperfusion (P ＜ 0.05).Caveolin-1 levels in cerebral cortex in sham group and XNJ group were significantly higher than that in model group 24 h,48 h and 72 h after ischemia-reperfusion (P ＜ 0.05).Conclusions After global ischemia-reperfusion,Xingnaojing (XNJ) injection could protect blood-brain barrier in virtue of regulating caveolin-1 protein level.

Objective To evaluate the clinical value of N-terminal pro brain natriuretic peptide (NT-proBNP) in septic children with myocardial damage.Methods From Jan 1 to Jun 30,2013,162 children confirmed with sepsis in PICU of Hu'nan Children's Hospital were enrolled in the study.Patients were divided into myocardical injury and non-myocardical injury group according to whether accompanied with myocardial injury.NT-proBNP,lactate dehydrogenase,creatine kinase isoenzyme (CK-MB),troponin Ⅰ (cTnⅠ),myoglobin(MB) of patients were measured within 24 h after admission.The NT-proBNP level between two groups was compared.The correlations between NT-proBNP and cTnⅠ,CK-MB were studied respectively.Results The NT-proBNP level[M(Q)] in myocardial injury group[3 632 (668.5,15 453.5) pg/ml] was higher than that in non-myocardial injury group[349 (169,1 500) pg/ml],which was significantly different(Z =91.881,P =0.000).The levels of NT-proBNP,CK-MB,cTnⅠ,MB were abnormal distributions.There were positive correlations between logNT-proBNP and logCK-MB (r =0.367,P =0.000),logcTnⅠ(r =0.304,P =0.001) and logMB (r=0.302,P =0.000).NT-proBNP value of 1 163 ng/ml had a sensitivity of 76％ and a specificity of 74％ to diagnose myocardial injury.Conclusion NT-proBNP could help to diagnose sepsis with myocardial damage.

Objective To summarize the clinical characters, diagnostic and therapeutic strategy of the cured patient with human H5N1 avian influenza pneumonia in mainland of China,and to provide effective experiences for the physicians to diagnose human avian influenza infection.Methods The clinical data of the cured patient with H5N1 avian influenza infection in China was analyzed.Results The patient was treated with short-term symmetrel and ribavirin for antiviral therapy companied with the lowdosage and long-term(4 weeks) glucocorticoid therapy.The CPAP assistant ventilation was used and the airway was kept unobstructed.The antibiotic was used to prevent and control the followed infection.The supportive treatment was applied to protect the organ′s function of the patient.The pathogenetic condition of the patient became better with the hemogram risen and the lungs pathological changes absorbed gradually.The chest CT reexamined at the 7th day of the hospitalized-term suggested that the left lung fibrosis started to be absorbed and it was obviously absorbed at the 16th day.The breath function and all the internal organs functions became better.The patient convalesced and left hospital at the 46th day.Conclusion In the human avian influenza infection,the pathogenetic condition may progress quickly after the pneumonia appears.The lung injury and lung fibrosis as well as the multi-organs dysfunction were emerged in the patient rapidly.The progression of disease can be controlled and the prognosis can be improved by the prompt and correct treatment.
