1.Progression of brain tumor stem cell markers
Journal of International Oncology 2014;41(12):899-901
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.
2.Complication of acute cerebral infarction and management
Chinese Journal of Practical Internal Medicine 2000;0(11):-
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.
3.Design of current measuring unit in near-infrared noninvasive blood glucose detection system
Chinese Medical Equipment Journal 2004;0(07):-
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.

Objective To analyze the CT features of hepatic artery and morphology changes of the liver in patients with cavernous transformation of the portal vein (CTPV). Methods Thirteen patients of CTPV without malignant hepatic tumor or other diseases being able to cause changes of hepatic artery such as cirrhosis and hepatophyma were collected. CT data was analyzed, and the arterial and morphology changes of the liver were observed. Results Left and (or) right hepatic arteries were found dilated in 10 patients (76.92%), and unusual flake like enhancement was found in artery phase in 3 patients (23.08%). Atrophy-hypertrophy complex (AHC) could be found only in 1 patient (7.69%). Conclusion Dilatation of hepatic artery manifests more hepatic artery blood supply, while obvious AHC is hardly found in CTPV.
9.The immunoregulatory effect of TLSF_(JM) on the levels of IP3、Ca~(2+) in activated T cells and the expression of Fos Protein
Chinese Journal of Immunology 1986;0(04):-
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.
