Objective To study the exocrine pancreatic function in critically ill children with septic shock,sepsis and hyperlactacidemia.Methods A total of 64 critical pediatric patients were admitted from Jan 2009 to Oct 2012,and clinical and laboratory findings including pancreatic function,and histopathological features and score after autopsy were reviewed.Results (1) Compared with non-septic shock children,the pancreatic pathology score and serum lipase in septic shock group were significantly higher and serum calcium was significantly reduced (P ＜0.05) ; (2) The pancreatic histopathology score was significantly increased in patients with elevated plasma lactate ≥2 times (P ＜0.05),but there were no significant differences in serum calcium and blood amylase and lipase between patients with elevated plasma lactate level and patients with normal plasma lactate level; (3) The concentrations of serum amylase,lipase and urinary amylase were significantly increased in patients with pancreatic histopathology score ＞4 points compared with score ≤4 points patients,but there were no significant differences in above three biomarkers between patients with score ≤3 points and patients with score ＞3 points.Conclusions The pancreas is vulnerable to damage easily occurred in septic shock children especially complicated with hyperlactacidemia.The pancreatic histopathology score ＞ 4 points can be as a sensitive and reliable indicator of pancreas 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.

Objective To investigate the relationship between sleep duration and obesity, and the risk of common chronic diseases in the occupational population in Shanghai City. Methods A total of 18 775 occupational individuals were selected as the study subjects using convenience sampling method in Shanghai City. Data on personal lifestyle behaviors and medical examination results were collected. The relationship between sleep duration and different types of obesity with dyslipidemia, hyperuricemia, hypertension, and hyperglycemia was analyzed. Results The incidence of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia among the study subjects was 24.9%, 16.2%, 11.5%, and 7.3%, respectively. The incidence of these four chronic diseases were higher in individuals with central obesity and suboptimal sleep compared to the control group (all P<0.01). Multivariate logistic regression analysis showed that suboptimal sleep combined with general obesity/overweight increased the risk of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia in the study subjects ［odds ratio (OR) were 2.40, 3.47, 3.30, and 2.79, respectively; all P<0.01］, after adjusting for age, gender, education level, marital status, occupation type, labor intensity, smoking, and drinking. Suboptimal sleep combined with central obesity also potentially increased the risk of these four chronic diseases (OR were 2.25, 3.09, 3.09, and 2.98, respectively; all P<0.01). Conclusion The incidence of common chronic diseases is relatively high in the occupational population in Shanghai City. Suboptimal sleep combined with different types of obesity increases the risk of common chronic diseases.

Objective To develop an appropriate comprehensive scale for mild cognitive impairment in Parkinson dis-ease(PD-MCI)due to various diagnostic methods for PD-MCI and a lack of consensus on the applicable neuropsychological scales for PD-MCI.Methods A total of 92 non-dementia PD patients with a confirmed diagnosis were enrolled in this study,and all patients were assessed using the comprehensive scale of five cognitive domains recommended by the Chinese version of PD-MCI guidelines and Movement Disorder Society(MDS).Based on the norms of healthy controls assessed by the same scale,the patients were divided into non-cognitive impairment PD group and PD-MCI group.The t-test was used to observe the consistency between groups;the receiver operating characteristic(ROC)curve was used to investigate the cut-off value of each scale with the highest sensitivity and specificity in identifying the impairment in each cognitive domain of PD-MCI;a binary lo-gistic regression analysis was used to determine the specific contents of the comprehensive cognitive domain assessment scale for PD-MCI.Results This study showed that the ten-point comprehensive cognitive domain assessment scale based on long-time memory in Brief Visuospatial Memory Test,Clock Drawing Test,digit span backward test,Trail Making Test A,Verbal Flu-ency Test,Trail Making Test B,Similarities,Boston Naming Test,long-time recall memory in Auditory Verbal Learning Test,and short-time recall memory in Wechsler Memory Scale-IV Logical Memory Test had a significant diagnostic validity in predict-ing PD-MCI,with an area under the ROC curve of 0.971(95%CI 0.941?1.000).Conclusion The recommended cut-off value can be used to perform a subtype analysis of PD-MCI and observe the outcome and clinical specificity of different subtypes of PD-MCI,and therefore,it has a certain clinical significance.

Objective To establish the delimitation norm of cognitive domain assessment scales for Parkinson dis-ease(PD)in Beijing,China,and to investigate the optimal cut-off values for determining abnormal neuropsychological as-sessments.Methods A total of 33 normal middle-aged and elderly individuals in communities and 89 patients with non-dementia PD were included in this study,and all subjects underwent global cognitive function screening and cognitive do-main assessments.According to whether Montreal Cognitive Assessment(MoCA)score was greater than 25 points,the pa-tients with PD were divided into mild cognitive impairment group(PD-MCI group)and normal cognition group(PD-NC group).In order to compare the consistency between PD-related cognitive domain assessment scales and global cognitive function screening in the diagnosis of PD-MCI,different cut-off values below the appropriate norms(i.e.,1.00 standard deviation,1.28 standard deviations,1.64 standard deviations,1.96 standard deviations below the mean)were examined for sensitivity,specificity,positive predictive value,and negative predictive value to obtain the optimal cut-off value.Results The delimitation norm of PD-related cognitive domain assessment scales was established for Beijing,and the re-sults showed that 1.96 standard deviations had the highest consistency in the diagnosis of PD-MCI and PD-NC,with the best sensitivity and specificity.Conclusion This study establishes the delimitation norm of PD-related cognitive domain assess-ment scales and fills the blank of the unbounded value of most domestic PD cognitive impairment assessment scales,and it also proposes the optimal cut-off value of abnormal neuropsychological assessment,which provides a reference standard for the cognitive domain assessment of PD patients in China and helps clinicians to identify cognitive decline in PD patients and adopt intervention measures in the early stage.
