1.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.

2.Influence of nursing intervention on hormone treatment compliance of patients with nephrotic syn-drome
Chinese Journal of Practical Nursing 2009;25(3):17-19
Objective To investigate the influence of nursing intervention on hormone treatment compliance of patients with nephrotic syndrome. Methods 130 patients with nephrotic syndrome who received hormone treatment were randomly divided into the experimental group and the control group ac-cording to the time of admission. The control group were treated with conventional nursing, and the ex-perimental group was given whole-process health education besides conventional nursing.Using question-naires, the level of relevant knowledge and medication compliance were compared between the two groups .The results underwent χ2 and t test. Results The treatment compliance was not significant be-fore nursing intervention, while after nursing intervention, the treatment compliance of the experimental group was better than that of the control group. The score of relevant knowledge about nephrotic syn-drome of the experimental group was higher than that of the control group Conclusions Active nurs-ing intervention can improve the health knowledge level of patients and improve the treatment compli-ance of hormone therapy.

The spindle assembly checkpoint ( SAC) is an important monitoring mechanism to monitor the connection between centromeres and microtubules and to ensure proper chromosome separation in human .Mitotic arrest defective protein(Mad)family,as an important part of SAC,plays a crucial role in the process of mitosis. Mutations or altered expressions of Mad may lead to abnormal separations of chromosomes and play a partial role in tumorigenesis ,poor prognosis and chemotherapy drug resistance .

Purpose:To investigate expression of keratinocyte growth factor(KGF) messenger ribonuclunc acid in human NSCLC and to study the role of KGF in the development of NSCLC. Methods:The expression of KGF mRNA in 50 cases with NSCLC was detected by in situ hybridization (ISH). Results:On ISH slides, positive KGF mRNA was mainly shown as fusiform stain in plasma of fibroblast and blood vessel smooth muscle cell in mesenchymal of NSCLC, also, some parenchyma cell plasma was stained. The positive rate of KGF mRNA in tumor(86%) is statistically higher than that in normal tissue(24%)(P

FGFR2 plays an important role in cell proliferation and differentiation and FGFR2 gene has its own genetic polymorphism. It has recently been demonstrated that this genetic polymorphism is associated with risk of development of breast cancer and clinically pathological factors

Objective To evaluate the effect of immune fluorescence chromatography on glycosylated hemoglobin (HbA1c). Methods The precision of immune fluorescence chromatography was evaluated with samples of 6.0% and 8.0% fixed value. Group of High performance liquid chromatography (HPLC) as control, HbA1c for 200 samples of EDTA-K2 anti-coagulated whole blood were detected by immune fluorescence chromatography to synchronous blinded trial. Results As to the precise of immune fluorescence chromatography in the samples of 6% and 8%, values of coefficient of variation were 5.1% and 5.3%, respectively. The linear regression equation of immune fluorescence chromatography and HPLC was Y=-0.110+1.021X and the correlation coefficient was 0.982. 6.0% and 8.0% as the cut-off value, kappa values were 0.950 (P < 0.001) and 0.922 (P < 0.001), respectively. Conclusion Immune fluorescence chromatography and HPLC is consistent with detection of HbA1c, which can be used for clinical detection of HbA1c.

In the context of precision medicine, although individual treatment of breast cancer under the guidance of molecular classi-fication has become the norm, a precision treatment program with increased efficiency and quality is still required. Compared with the traditional real-time fluorescent quantitative polymerase chain reaction (PCR), the droplet digital PCR (ddPCR) has obvious advantages in the detection of rare mutations and copy number variations, as well as the integration with the second-generation-sequencing tech-nology. This paper reviews the application of a ddPCR platform in different breast cancer subtypes and explores new horizons of breast cancer research through the ddPCR technology.

Objective:To develop a catalytic system for the asymmetric Morita-Baylis-Hillman ( MBH) reaction of conjugated ni-troalkene with activated aldehyde, and screen out the chiral catalysts with high activity and enantioselectivity. Methods: Totally 21 chiral organocatalysts were applied in the asymmetric MBH reaction ofβ-nitrostyrene with ethyl glyoxylate, and the ee value was deter-mined by chiral HPLC. The effects of temperature, solvent and substrate ratio on the catalytic reaction were investigated. Results: In the presence of cinchona alkaloid catalyst (DHQ)2AQN, β-nitrostyrene reacted with ethyl glyoxylate in toluene at 0℃ affording the MBH adduct in 60% yield with good enantioselectivity (up to 56.9% ee). Conclusion: The bis-cinchona alkaloids with aromatic bridging group are the efficient catalysts for the asymmetric MBH reaction ofβ-nitrostyrene with ethyl glyoxylate, and moderate isolated yield and enantioselectivity are obtained.
