AIM:To investigate the effect of Gln deprivation on growth and differentiation of primary APL cells. METHODS: The primary APL cells were collected from 18 cases of APL patients' periphery blood, the patients had not been treated. The cells were incubated in RPMI 1640 without or with different contents of glutamine and with 10% fetal calf sera, at 37℃,5% CO 2 and saturation humidity for 4 days.The initial living cell density was 5?10 8/L. After 4 days incubation,the cells were counted,collected, smeard and stained with Wright-Giemsa, DNA, POX, NAE and NaF inhibition,gulping ink and NBT etc. cytochemical technology. The stained cells were investigated under oil immersion lens. RESULTS: The living cell density became (54.28?4.28)% of the initial in glutamine deprivation group, but the living cell density in control with 4 mmol/L Gln was (108.56?12.27 )% of the initial ( P

[Objective] To introduce the Professor SHI Yanping's experience in treating adenomyosis with traditional Chinese medicine. [Methods]Through clinical learning with the teacher and systematic reading literatures about adenomyosis, the author summarized the teacher 's academic thoughts and clinical treating experience of the disease from the etiology and pathogenesis,fundamental law of treatment ,and medication characteristics,and one proven case was presented respectively.[Result] Professor SHI thinks the basic pathogenesis of adenomyosis is deficiency of kidney and blood stasis, accompanied by phlegm dampness, the proof is vacuity, treatment should be staged in terms of different periods:non menses-paying attention to eliminating mass and strengthening the body resistance, creatingNei Yi Ting Fang;menses-paying attention to regulating qi and blood by warming drugs, makingXin Gui Zhi Tong Fang;and at the same time,we have to pay attention to the adjustment of life style.All those lead to a good clinical effect. [Conclusion] The rich experience of Professor SHI in treating this disease might be worthy of promotion and learning,which has a good effect on relieving the discomforts and improving the quality of life in patients.

Objective To study the clinical and THR?gene mutation of two cases of pituitary thyroid hormone resistance. Methods The clinical data and peripheral blood samples of the patients and their family members were collected, and then DNA was isolated. PCR and direct sequencing techniques were performed to determine if there were mutations in their THR?gene. Results No mutation was found in exon 1-10. Conclusion Pathogenesis of sporadic pituitary resistance to thyroid hormone usually has no relation with mutation of THR?gene.

Objective To observe the occurrence of hyperhomocysteinemia among patients suffering from cerebral infarction,and explore the possible risk factors.Methods Data of 144 cerebral infarction patients were collected from a tertiary hospital in Tianjin including gender,age,diabetes mellitus,hypertension,smoking,alcoholism,plasma homocysteine,HbAlc and biochemical criterion.Two groups were created as the hyperhomocysteinemia group and the control group based on serum homocysteine levels.Risk factor for hyperhomocysteinemia was analyzed by application of Logistic regression.Results Logistic regression analysis revealed that hyperhomocysteinemia was associated with gender,smoking,drinking and HbAlc levels in patients.Conclusions Male,smoking,drinking and diabetes mellitus were the possible risk factors in cerebral infarction patients.

Chemical constituents in the mature fruit peels of Sinocitrus chuana Hort were studied systematically. Five compounds were isolated and identified. They were hesperidin( Ⅰ), nobiletin(Ⅱ) tengeretin(Ⅲ), 4', 5, 7, 8-tetramethoxyflovones(Ⅳ) and synephrine(Ⅴ). Of them the fourth was isolated from this genus for the first time.

Objective To get a high affinity peptide of vascular endothelial growth factor receptor 3 (VEGFR3) as a potent carrier targeted to lymphangiogenesis of ovarian cancer via the technology of phage display. Methods Solid-phase was panned with direct VEGFR3 extracellular protein coating, then the unbound phage was washed away and the eluted phage was amplified. The positive phage clones were identified by ELISA and sequenced, and the affinity and specialty were identified by competent ELISA. Results After four-round bio-panning, the enriched positive phage clones were identified by ELISA. Eight positive phage clones were sequenced and 5 were consensus (WHGSLKQNLWWY). The short peptide displayed on screened positive phage could bind specifically to VEGFR3, and the binding could be inhibited by natural antibody VEGF-D. Conclusion The phage clone (phage-WHGSLKQNLWWY) obtained via bio-panning of peptide library has a high affinity with VEGF receptor 3. The peptide could be a potent carrier targeted to VEGFR3.
