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.

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.

OBJECTIVETo determine lobetyolin in the root of Codonopsis tangshen from the various cultivation areas.

METHODA Supelco Discovery C18 Column (4.6 mm x 250 mm, 5 microm) was used with acetonitrile-0.5% acetic acid in water (20:80) as the mobile phase and UV detection was at 268 nm.

RESULTTwenty-four batches of the samples were analyzed. The content of lobetyolin ranged from 0.0403-0.9667 mg x g(-1).

CONCLUSIONThe method was simple, reproducible and reliable. It can be used to control the quality of C. tangshen.

OBJECTIVETo investigate the status of job burnout in traditional Chinese medicine (TCM) doctors and explore the effect of occupational commitment on job burnout.

METHODSA test of occupational commitment and job burnout was carried out in 507 TCM doctors with occupational commitment questionnaire and Maslach Burnout Inventory-Human Services Survey (MBI-HSS).

RESULTSThe age group of < 30 years scored lowest (2.352 +/- 0.660) in personal accomplishment compared with 30 years old group and 40 years old group [(2.136 +/- 0.704) and (2.127 +/- 0.628) respectively] (P < 0.01). The score of emotional exhaustion and depersonalization increased with educational levels. There was significantly negative correlation between job burnout and occupational commitment (P < 0.01). Occupational commitment had significant effect on job burnout (P < 0.01). Occupational trouble commitment was a major predictor for emotional exhaustion (P < 0.01). Professional self-efficacy commitment was a major predictor for depersonalization (P < 0.01). Affective commitment was a major predictor for personal accomplishment (P < 0.01).

CONCLUSIONOccupational commitment is a good predictor for job burnout. Improving occupational commitment is an important measure to prevent job burnout.

OBJECTIVETo observe the effect of acupuncture at the whole points of Hand Jueyin pericardium meridian on the amplitude of low frequency fluctuations (ALFF) of healthy people in resting state (R1) functional magnetic resonance imaging (fMRI).

METHODSTotally 16 healthy subjects received structure scan of T1 and T2. Then two fMRI scans were conducted for each participant. fMRI included the resting-state scan (R1; the scanning time was 8 min 6 s), the stimulating-acupoint scan (AP; the scanning time was 8 min 6 s). fMRI data acquisition from structure scanning and function scanning were processed with format conversion and statistical analysis.

RESULTSUnder R1 state, brain regions with activated ALFF signals included bilateral superior frontal gyrus, medial frontal gyrus, middle occipital gyrus, precuneus, superior temporal gyrus, and cingulate gyrus. Under the AP state, brain regions with activated ALFF signals were bilateral superior frontal gyrus, medial frontal gyrus, middle temporal gyrus, left fusiform gyrus, precuneus, posterior cingulate, and declivis. Compared with R1 state, obvious difference of ALFF signal areas of the brain caused by acupuncture at pericardium were: bilateral cuneus, precuneus, left posterior cingulate gyrus, right middle occipital gyrus, and right occipital lingual gyrus.

CONCLUSIONAcupuncture at the whole points of Hand Jueyin pericardium meridian could significantly change inherent activity states of the cerebral cortex, especially in bilateral superior frontal gyrus, medial frontal gyrus, and precuneus.
