The principle and structure of the near-IR laser spectrum noninvasive blood glucose detection system are introduced in the paper. To meet the detection demand of the little DC current signal in the system,the current measure methods are analyzed. The hardware and software structure are discussed in the end.

Complications that follow ischemic stroke are common,frequency ranging from 28% to 95%.It may either directly lead to death or prevent optimal recovery.54% of deaths after ischemic stroke are attributed to medical complications.Most complications occur during the first week,and stroke severity is the most important risk factor.The common serious medical complications are chest or urinary tract infection,deep venous thrombosis,pulmonary embolism,cardiac events,gastrointestinal bleeding,hyperglycemia,pressure sores.Falls,shoulder pain and depression are also common complications.Most of medical complications are preventable or treatable to some extent if recognized,so preventive strategies and appropriate treatment should be employed as early as possible.Prevention,early recognition,and management complications could improve short-term and long-term prognoses after ischemic stroke.

Brain tumor stem cells (BTSCs) play a key role in tumorigenesis and tumor development.There are a group of special markers in the surface of brain tumor stem cells,which can sorts stem cells,precursor cells and cancer stem cells.In recent years,the studies of CD133,Nestin,high-mobility group A1,A2B5 have made some breakthroughs.

Objective To analyze the imaging features of endometrial carcinoma derived from multimodal MRI.Methods MRI scan was performed in 45 patients with biopsy-proved endometrial carcinoma,including conventional MRI,diffusion weighted imaging(DWI),dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI),and time-signal curve (TIC).Results The diagnosis rate of DCE-MRI combined with DWI was 93.3%, and that of conventional MRI was 77.8%.Tumor differentiation was negatively correlated with ADC and rADC, and significant difference was found between G2 and G3 as well as G1 and G3 (both P<0.05).There was no significant difference between G1 and G2 (P>0.05).Of the 45 cases, 43 showed TIC type Ⅰ and type Ⅱ, and 2 showed TIC type Ⅲ, while the normal myometrium was mainly type Ⅲ curve.The difference of signal intensity of each phase (D), and enhancement rate (ER) of the lesions were lower than those of the normal myometrium.The difference was statistically significant at the phase of >30 s(P<0.05),the peak time of the former was (50±10) s.Conclusion Multimodal MRI is of great value in preoperative staging and grading of endometrial carcinoma.

The immunoregulatory effect of TLSF_(JM) on the levels of IP3,Ca~(2+) in activated T cells andthe expression of Fos protein was investigated by ABC immunohistochemistry technique and Fu-ra-2/AM labelled T cells and anion-exchange chromatography techniques in this paper.The re-sults showed that TLSF_(JM) can the same time,it can strongly inhibit the levels of IP3、Ca~(2+) in ac-tivated T cells.

Objective To set up an antibody-capture ELISA method to detect the Japanese encephalitis virus(JEV)antibody.Methods ELISA plate was coated with the monoclonal antibody which was specific to the envelope protein epitope E39 of JEV,JEV SA14-14-2 strain as the source of antigen was used to absorb the monoclonal antibody,the absorbed virus used to capture the JEV'S antibody.The antibody that captured ELISA was established.The indirect ELISA method using the virus particles from cell culture was compared with coating ELISA plate,105 clinical serum were checked.Results The background in indirect ELISA assay could not be abscised,positive and negative serum diluted in a ratio of 1:10,1:100,1:1000,the relative value of A posative/A negative were 1.02,0.99,1.13,all<2.1.But the antibody-captured ELISA method when the serum dilution was 1:10,1:100,the A posative/A negative were 3.57,2.94,all>2.1;when the dilution was 1:1000,the A posative/A negative was 1.42,<2.1,it meant the method could distinguish the positive and negative serum efficiently when the dilution Was 1:100,the background problem in indirect ELISA assay could be solved.Antibody-capture method was used to check 105 serum samples,the A posative/A negative over a range of 0.257～0.321(0.262±0.050),all<2.1,no positive sample found.Conclusion The antibody-capture ELISA method has been preliminary set up with a high specificity,capable of quickly identifying JEV from other virus.
