This study is to compare the influence of CYP2D6 *3 and *4 genotypes and phenotypes on the metabolic activity of CYP2D6 in Chinese Han, Uygur and Kazakh ethnic groups. Allele specific amplification (ASA) was used to determine the CYP2D6*3 and CYP2D6*4 genotypes. Phenotypes of CYP2D6 in all subjects were determined using dextromethorphan as probe drug by HPLC methods. Among the 132 Han subjects, one subject (0.76%) exhibited the *1/*3 combination, and one (0.76%) exhibited the *1/*4. Among the 136 Uygur subjects, 4 subjects (2.94%) showed the *1/*3 combination, 12 (8.82%) showed *1/*4, 4 (2.94%) showed *4/*4, and one (0.74%) showed *3/*4. Among the 116 Kazakh subjects, 2 (1.72%) exhibited the *1/*3 combination, 7 (6.03%) exhibited *1/1*4, and one (0.86%) showed *4/*4. This research revealed significant differences in the occurrence frequencies of the CYP2D6 genotype between Han and Uygur ethnic groups, as well as between Uygur and Kazakh populations. However, no difference was found between Han and Kazakh populations. In addition, the prevalence of PMs of the Uygur is comparable to that of the Caucasians. However, the molecular mechanism underlying the poor metabolism is different in these two populations.

Objective To study the MRI findings of HE and the pathological mechanism and to improve the diagnosis and differential diagnosis of HE. Methods Five patients of HE diagnosed by clinical and laboratory examination were examined with conventional MRI scan. Additional DWI, MRA and enhancement MRI scan were performed on 3 patients in which abnormal findings was detected on the conventional MRI. The distribution of lesions and signal characteristics were analyzed. The ADC values of the lesions and of the contralateral non-lesion area were measured. Moreover, the possible pathological mechanisms of HE were discussed on the basis of changes of clinical and imaging manifestations in the two cases with serial clinical and MRI data. Results Of 5 patients, brain abnormalities were found in 3 cases,which showed scattered spotted supratentorial white matter lesions of isointensity on T1 WI and DWI, and high signal intensity on T2WI and fluid-attenuated inversion recovery (FLAIR). Meanwhile, multiple plaque-like lesions involving both white matter and gray matter were found, mainly located at the basal ganglia nuclei, hippocampus and cingulate cortex. The lesions demonstrated iso-or hypo-intensity on T1 WI,and iso-or hyper-intensity on T2 WI, FIAIR and DWI at the initial stage. No enhancement was found in these lesions and MRA disclosed no remarkable findings. The ADC value of the lesions [ (0. 449 ± 0. 092) ×10-3 mm2/s] was decreased significantly compared with the contralateral noninvolved area [ (0. 838 ±0. 062) × 10-3 mm2/s] at the early onset. In 2 cases with glucocorticoid therapy, together with symptom relief, MRI follow-up scan demonstrated the reduction of lesion volume, the signal change to hyperintensity on T1 WI and hypo-intensity on DWL The ADC of the lesions increased significantly. Conclusion The MRI could be one of the effective tools for diagnosis, differential diagnosis, and judging the prognosis and therapeutic results of HE. Meanwhile, it may be a non-invasive method to study the pathological mechanism of HE.

Objective To investigate the effects of down-regulation of lemur tyrosine kinase 3 (LMTK3) on the cytobiological behaviors of human lung cancer A549 cells.Methods The expression of LMTK3 in A549 cells was interfered with small hair RNA (shR-NA),and the expression level of LMTK3 was determined by RT-PCR.The effects of LMTK3 on the proliferation,migration,cell cycle and apoptosis of A549 cells were determined by the CCK-8 assay,scratch assay,Transwell assay and flow cytometry,respectively.Results The shLMTK3 cells with stably low expression of LMTK3 and control cells (Scramble) with normal expression of LMTK3 were successfully obtained.The relative proliferation rates of shLMTK3 cells cultured for 24,48 and 72 hours were significantly lower than those in the control cells (0.305 ±0.018 vs 0.354 ±0.011,t =5.24,P＜0.01;0.461 ±0.044 vs 0.551 ±0.027,t =3.91,P ＜0.01;0.74 ± 0.029 vs 0.881 ± 0.028,t =7.70,P ＜ 0.01).The relative migration rate of shLMTK3 cells 24 hours after scratching was significantly lower than that of control cells (0.51 ±0.096 vs 1.00 ± 0.029,t =4.81,P ＜ 0.01).Transwell assay showed that the number of migration cells in shLMTK3 group was significantly less than that in Scramble group (161 ±9.29 vs 308.66 ± 17.60,t =7.42,P ＜ 0.05).The results of flow cytometry showed that shLMTK3 cells were blocked at G1 phase (t =4.35,P ＜ 0.05),and that the inhibition of LMTK3 had no influence on the apoptosis of A549 cells.Conclusion Down-regulation of LMTK3 expression in human lung cancer A549 cells may inhibit the proliferation and migration of A549 cells significantly,indicating that the abnormal expression of LMTK3 in lung carcinoma cells may regulate the biological behaviors and progression of tumors.

Objective To clone the gene of arginine kinase (AK) from Periplaneta americana, produce its recombinant protein and investigate its allergenicity. Method The cDNA of AK was cloned using specific primers from the total RNA of P. americana. The cloned gene was inserted into pMD18-T vector and digested by BamHI and HindⅢ. The cDNA was sequenced and subcloned into pET-28a expression vector. The cloned AK cDNA gene was expressed in Escherichia coli BL21 (DE3) by IPTG induction. The recombinant AK (rAK) was purified by metal (Ni2+) chelating affinity chromatography. Its allergenicity was examined by both Western blotting and enzyme-linked immunosorbent assay (ELISA). Result The cloned cDNA ORF sequence (Accession no. EU429466) contained 1 068 bp and encoded 365 amino acids. Its sequence homology with the published one (Accession no. AY563004) was 99.9% at nucleotide level. The allergen rAK was highly expressed in E. coli BL21 (DE3) as a soluble protein mainly with the molecular weight of about Mr 45 000 under induction of IPTG and purified by 6-His-tag purification system. Both in the non-denaturalization and denaturalization conditions, the recombinant allergen was identified as its affinity to IgE antibodies from the cockroach-allergic patient sera by Western blotting and ELISA. Conclusion The recombinant cockroach arginine kinase has been obtained with proper allergenicity.

Objective To study the anti-tumor effect and mechanism of bortezomib in primary acute leukemia cells from elderly patients.Methods Primary acute leukemia cells were treated with bortezomib 50-5000 nmol/L for 24-48 h,cell proliferation was analysed by MTT assay; apoptosis of primary acute leukemia cells was observed by fluorescence microscopy and flow cytometry; protein expression of bcl-2 and Bax was detected by Western blot.Results The cell viability was 90 ％ and 70 ％ when leukemia cells were treated with 50 and 5000 nmol/L bortezomib for 24 h,respectively.Meanwhile,cells showed (10.2±2.3) ％ and (13.3±3.3) ％ apoptosis.With prolonged treatment for 48 h,cell viability decreased to 86 ％ and 60 ％,respectively,while the apoptosis rates were increased to(18.4±3.9) ％ and(20.7±3.7) ％.Compared to the control group 0 nmol/L bortezomib,the differences were statistically significant (F =53.76,F =7.74,F =54.49,F =16.94,all P values ＜ 0.05).With the increase of bortezomib concentration,the bcl-2 protein expression was decreased,while Bax was up-regulated.Conclusion Bortezomib can inhibit primary leukemia cells from elderly patients proliferation and induce apoptosis.The mechanism may be associated with the changes in bcl-2 family protein expression.
