1.Establishment of a sandwich ELISA method for measuring soluble IL-2 receptor
Chinese Journal of Immunology 1985;0(06):-
Two kinds of mouse monoclonal antibodies which recognize distinct epitopes of the IL-2 receptor (a chain) were used to establish a sandwich ELISA for measuring soluble IL-2 receptors. The results indicated that this method is sensitive and specific for detecting soluble IL-2 receptors of cell culture supernatant and serum from both healthy donor and patients with leukemia. Therefore this sandwich ELISA method is useful for basic and clinic immunology research.
2.Studies on the requirements for growth of Epstein-Barr Virus thransformed human lymphoblastoid B cells at low cell density
Chinese Journal of Immunology 1985;0(02):-
We obtained human lymphoblastoid B cells secreting human antibodies IgM and IgG to HFRS virus by Epstein-Barr virus(EBV)transfomation of PBMC.Conditioned media from the supernatant of a human fibroblast cell CRL1506 culture and irradiated CRL1506 cells as feeder cells could markedly promote the growth and antibody produotion of the human B lymphoblastoid cells at low cell density.It was shown that conditioned media contained a high level of interleukin 6(IL-6) .These results would be very useful for human monoclonal antibody technique including improving human B lymphoblastoid cell growth at low cell density and enhancing cloning efficiency andantibody production.

To study the changes in vestibular function in Parkinson's disease patients, and its significance, eletronystagmography (ENG) was used to examine 54 patients with Parkinson's disease, and also 20 hea thy elderly subjects. The results of vestibular function tests including sensory organization test, nystagmus test, cold caloric test and positional test of these two groups were recorded for statisticed analysis. It was found that the rate of vestibular dysfunction in Parkinson's disease patients were 81 4%, and that of the controls 30%. There was significant difference between the two groups ( P

The characteristics of master dissertation topics in medical library and information science and their se-lection methods were analyzed with the dissertations published since 2004 as the study object.The challenges and development trend in training of qualified personnel of medical library and information science were summarized , which may provide certain evidence for the training of masters in medical library and information science .
5.Current Development of Breast-Specific Gamma Imaging (BSGI) Technique.
Chinese Journal of Medical Instrumentation 2015;39(2):108-112
Breast-Specific Gamma Imaging (BSGI) is an improved and optimizing nuclear medicine breast imaging technique on the basis of traditional gamma camera. It uses a high resolution, small field-of-view scintilla detector. The detector is designed with 3 073 individual detector crystals and 48 position-sensitive photomultiplier tubes. The FOV of detector is 15 cm x 20 cm, and optimal system resolution for breast imaging is 3 mm, can detect the diameter of only 2-3 mm small lesions. BSGI has better sensitivity in detecting subcentimetre or nonpalpable breast cancer. The sensitivity for the diagnosis of breast cancer is high, not influenced by the density of the breast tissue, implants, architectural distortion-or scars from prior surgery or radiation. So it is called a high resolution, small field-of-view breast-specific gamma camera.

6.Study on quality standard for Jianweishu Granule
Chinese Traditional Patent Medicine 1992;0(10):-
Objective: To establish the assay methods for paeoniflorin and baicalin in Jianweishu Granules (Radix Scutellariae, Radix Paeoniae Alba, Radix Astragali seu Hedysari, Radix Notoginseng, etc.). Methods: Radix Astragali, Radix Notoginseng; Radix Paeoniae Alba and Herba Dendrobii in Jianweishu Granule were identified by TLC. The paeoniflorin and baicalin in Jianweishu Granule were determined by HPLC on shim pack CLC ODS C 18 Column (6.0mm?150mm,10?m); using methanol water phosphoric acid (47∶53∶0.2) and methanol water (30∶70) as mobile phases, respectively; the flow rate were at 1.0 mL?min -1 ; the detection wavelength were 280nm and 230nm, respectively; the column temperature were at room temperature and 40?C respectively. Results: The average recoveries are 98.94% and 98.67%. RSD are 2.31% ( n =5) and 1.36% ( n =5). Conclusion: The methods are simple, sensitive, accurate and reproducible.
7.Multifocal visual evoked potential in the detection of glaucomatous field defects
Ophthalmology in China 1994;0(02):-
Objective To evaluate the effect of multifocal visual evoked potential(mfVEP)on the detection of glaucomatous field defects. Design Case-controlled study. Participants 20 healthy individuals and 20 patients with primary glaucoma accepted mfVEP test. Methods 20 healthy individuals and 20 patients with primary glaucoma were tested with RETIscan multifocal VEP System 3.20 and OCTOPUS 101 automated perimetry G2 test program. Amplitudes were measured and interocular response asymmetry coefficient (RAC) was calculated for each site from all participants. The abnormal areas from mfVEP test were compared with field defects from automated perimetry. Main Outcome Measures Amplitude, RAC. Results 90% of suffered eyes showed at least 3 adjacent points had an amplitude decrease or RAC outside 2 standard deviations (SD) from healthy individual database, in which 63% showed at least 3 adjacent points had an amplitude decrease outside 2 SD from normal database while 70% showed at least 3 adjacent points had a RAC outside 2 SD from normal database. 2 patients (2 eyes) had field defects in mfVEP though automated perimetry showed normal field. None of the healthy showd field defects in mfVEP test. Conclusions mfVEP could be used to detect field defects of glaucoma.
8.Erythropoietin and neuron apoptosis:Signal pathway
Chinese Pharmacological Bulletin 2003;0(12):-
Apoptosis is a main death pattern in many nervous system disease.Erythropoietin(Epo)has been originally characterized as the principal regulator of erythropoiesis by stimulating the proliferation and differentiation of erythroid precursor cells.In recent years,many experimental studies have shown that both Epo and EpoR(erythropoietin receptor)are functionally expressed in the nervous system and that this cytokine exerts a remarkable neuroprotection against nerve cell apoptosis.This article reviews neuroprotective of Epo against apoptosis and outline the involved molecular mechanisms.
