BACKGROUND: It is still a problem to achieve early and accurate diagnosis of Alzheimer's disease, and delayed treatments often occur in a large number of patients because of late diagnosis or misdiagnosis. Therefore, the development and improvement of related bioanalytical methods are of great importance for the biomarker detection of Alzheimer's disease which is still lack of means that are sensitive, efficient and low-cost. OBJECTIVE: To summarize the diagnostic methods and related biomarkers of Alzheimer's disease, and to sum up the research progress in novel biomimetic receptors for the early detection of Alzheimer's disease biomarkers. METHODS: PubMed, CNKI and Wanfang databases were used to search articles related to the biomarker studies of Alzheimer's disease and relevant studies about methods of biomarkers detection published from 2000 to 2016. The key words were "Alzheimer's disease, biomarkers, detect/detecting/detection" in Chinese and English, respectively. Finally 40 articles were obtained for the review. RESULTS AND CONCLUSION: At present, the bioanalytical methods used for biomarker detection of Alzheimer's disease mostly utilize antibodies as recognition and capture elements of biomarkers, but there are some limitations using traditional antibodies as detection receptors. Thus, novel biomimetic receptors can be substituted for conventional antibodies. Novel biomimetic receptors have high specificity, small size, low production costs and high product stability, and their chemical modification process is relatively convenient. Biomimetic receptors developed for protein analysis include aptamers, polypeptide receptors, peptoid receptors, molecularly imprinted polymers, nanobodies, gelsolin and cucurbit urils. Detection of biomarkers with novel biomimetic receptors instead of conventional antibodies will be more accurate and timely in the early diagnosis of Alzheimer's disease.

Objective To analyze the affection and clinical significance of CD26/DPP4 on CD4+T cells and its cytokines in patients withCrytococcalMeningitis.Methods Peripheral blood was collected from 36 patients diagnosed withCrytococcal Meningitis in Changhai Hospital and Changzheng Hospital,Shanghai from August,2011 to December,2015,meanwhile 36 health controls’was also acquired.Peripheral blood mononuclear cell (PBMC)was separated by density gradient centrifuga-tion,CD26+CD4+T and CD26-CD4+T cell groups were classified by Flow Cytometry,the expression level of cytokines was tested by reverse transcriptase-polymerase chain reaction (RT-PCR).The correlation between DPP4 activity,CD26+CD4+T (%)and APACHE II score,IL-17,TNF-α,IL-4,IFN-γwas measured by Pearson coefficient.Results CD26+CD4+T(%)between experimental and control groups was 13.35±3.83 vs 8.39±2.14 (t=6.78,P<0.000 1).DPP4 activity was 50.89±17.21 mU/ml vs 73.83±20.24 mU/ml (t=5.18,P<0.000 1),with statistically significant differences.In ex-perimental groups,CD26+CD4+T (%)was positively related with APACHE II score,IL-17,TNF-α(r=0.431,0.564, 0.688,P=0.003 8,0.001,0.004 6).DPP4 activity was negatively interrelated with APACHE II score,IL-17,TNF-α,IFN-γ(r=-0.544,-0.489,-0.678,-0.734;P<0.001).Conclusion CD26/DPP4 may be involved in the pathogenesis of Crytococcal Meningitis through regulation of Th subgroups,and it was the potential therapeutic target and the predicted marker of the disease.

Objective To investigate the instructive role and clinical effect of invasive intracranial pressure monitoring in treating bilateral posttraumatic acute diffuse brain swelling(PADBS).Methods A total of 52 consecutive patients with bilateral PADBS managed under invasive intracranial pressure monitoring between October 2009 and December 2010 were enrolled as the study group.Another 53 patients with bilateral PADBS managed with non-intracranial pressure monitoring from February 2007 to September 2009 were set as the control group.The clinical outcomes of the two groups were compared.Results The ratios of good recovery[Glasgow Outcome Scale(GOS)=5 points]and severe disability(GOS=3 points)were 59.6%(31/52)and 11.5%(6/52)respectively in the study group,but 35.9%(19/53)and 28.3%(15/53)respectively in the control group(P<0.05).The death rates of the study and control groups were 5.8%(3/52)and 9.4%(5/53)respectively(P>0.05),and the average hospital stay was(34.35±17.50)days and(42.43±22.17)days respectively(P<0.05).Conclusion Durative monitoring of invasive intracranial pressure in treatment of bilateral PADBS can improve prognosis,shorten hospital stay and therefore is worthy of clinical application.

Objective:To observe the effects of Chinese herbal compound'Jisuikang'on the phagocytosis of microglia and the regeneration of injured neurons in co-culture system.Methods: Prepared drug serum of 'Jisuikang′ and isolated and identified the primary neuron and microglia.The neuron cells were induced apoptosis by glutamic acid and the microglia cells were predisposed by drug serum of'Jisuikang'.Then,the co-culture system of injured neurons and microglia cells was established.24 h and 96 h after co-culture,engulfment of neuron debris by microglia cells and regeneration of injured neurons were observed by immunofluorescence double labeling method.Results: 24 h after co-culture,middle and high dose of'Jisuikang' showed greater phagocytic percentage and phagocytic index than that of control.In comparison of LPS,high dose of'Jisuikang' showed no significant difference.96 h after co-culture,first grade of neuritis of middle and high dose of'Jisuikang' were more than that of control,and there were no significant difference in comparison of LPS.Neuritis' mean length per cell of middle and high dose of'Jisuikang' were larger than that of con-trol.Neuritis' mean length per cell of high dose of'Jisuikang' showed significant difference in comparison of LPS.Conclusion:Traditional Chinese medicine compound'Jisuikang'may enhance engulfment of neuron debris by microglia to improve local microenvi-ronment,which promote the repair and regeneration of injured neurons.

Objective To understand the pathogenic distribution and epidemiological trend of hand-foot-and-mouth disease (HFMD),and provide evidence for the prevention and control of HFMD.Methods Children who were diagnosed with HFMD in a hospital between January and December 2015 were investigated,real time fluorescence PCR was used to detect enterovirus universal type EV,enterovirus 71 (EV71),and Coxsackievirus A16 (CoxA16) in specimens from children with HFMD.Positive rates and distribution of various types of EV among children of different months,genders,age groups,and infection types were analyzed.Results A total of 837 throat swab specimens from HFMD children were collected in 2015,380 (45.40%) of which were EV positive specimens.Virus typing showed that 110 (28.95 %),7 (1.84 %),6(1.58 %),and 257(67.63 %) were positive specimens for EV71,CoxA16,EV71 + CoxA16,and other types of EV.HFMD had a high prevalence since April,reached a peak in May-June,and remained high incidence in July-December.Positive rates of EV in children of different months were statistically different (P<0.05).The age of onset was mainly in children under 3 years.Positive rates of EV and constitute ratios of different types of EV in children of different age groups were all statistically different (all P<0.05).The positive rate of EV in severe HFMD cases was higher than common cases (65.34% vs 27.06%,P<0.001).The proportion of severe cases in children with EV71 infection and other types of EV infection were 90.00% and 60.70% respectively;children with EV71 + CoxA16 double infection were all severe cases.Constitute of EV types in children with different infection types was statistically different(P<0.001).Conclusion In 2015,EV infection in hospitalized children with HFMD in this hospital was mainly caused by other types of EV (nonEV71 and non-CoxA16),the high prevalence season,high-risk population under 3 years of age,and severe cases should be paid high attention,prevention and treatment should be performed well.
