International Journal of Laboratory Medicine 2014;(20):2784-2785
Objective To investigate the relationship between homocysteine(Hcy)and blood uric acid(UA)in the patients with type 2 diabetes mellitus(T2DM)complicating hypertension.Methods 85 patients with T2DM complicating hypertension were se-lected as the groupⅠ,78 patients with simple T2DM as the group Ⅱ and 74 individuals with healthy physical examination as the group Ⅲ.Hcy,UA,TC,TG and HDL-C were measured in all the subjects.Results Compared with group Ⅲ(control),the levels of Hcy,UA,TC and TG in the group Ⅰand groupⅡwere significantly increased(P <0.05),but the level of HDL-C was significantly decreased(P <0.05).Compared with the group Ⅱ(T2DM),the levels of Hcy,UA,TC and TG in the group Ⅰwere significantly in-creased(P <0.05 ),but the level of HDL-C was obviously decreased,the difference had statistical significance (P <0.05 ).There was good positive correlation between the Hcy level and the UA level in the patients with T2DM complicating hypertension (r =0.658,P <0.05).Conclusion The levels of Hcy and UA are significantly increased in the patients with T2DM especially complica-ting hypertension.High Hcy and high UA are the important risk factors of T2DM complicating cardiocerebrovascular diseases.

Results of experiments such as ammonia steaming test in mice and citr ic acid test in guinea pigs, phenol red secretion test in mice and capillary exp ectorant test in rats, in-vivo and in-vitro antiasthmatic tests in guinea pigs p roved that Tankeqing capsule had good antitussive, expectorant and antiasthmatic effects and a significant time-effect relationship was showed. The antitussive effect and expectorant effect arrived to the peak in 1-6h after oral administrat ion, and the antiashmatic effect in about 1h.

Objective To investigate the effect of Shuyusan on the behavior of chronic stress induced depression model rats, as well as concentrations changes of norepinephrine (NE), dopamine (DA) and serotonin (5-HT) in cerebral cortex. Method Fifty mice were randomly divided into 5 groups:normal control group, model group, amitriptyline group, and high/low dose prescription group of Shuyusan. Except normal group, the other groups were given the chronic mild unpredicted stress for 21 days. After 21 days different stimulation, open-Field test was used to estimate the behavior of rats, the concentrations of NE, DA and 5-HT were detected with fluorescence spectrometer method. Results Horizontal and vertical motion of the model group was significantly lower than that of the control group (P

Objective To investigate the influences of 5-azacytidine (5-Aza) with different concentrations on mesenchymal stem cells (MSCs) proliferation and differentiation into myoblasts. Methods Bone marrow-derived MSCs of 4 weeks Wistar rats were separated and purified, and then treated with 5-Aza with different concentrations. The growth ability of cell was assayed with methyl thiazolyl tetrazolium (MTT) method. The expression of skeletal muscle actin in MSCs was determined with reverse transcription polymerase chain reaction (RT-PCR) and electrophoresis after MSCs were induced. Results The cell proliferation was not affected by 0 and 1 ?mol ? L-1 5-Aza . There were expressions of skeletal muscle actin treated with 3 -12 ?mol ? L-1 5-Aza. Some cells were obviously enlarged at the 9th day after induction and myotubu-like cells were found at the 12th day when treated with 9 and 12 ?mol ? L-1 5-Aza. 20 - 30 ?mol ? L-1 5-Aza induced the toxic effect on proliferation of MSCs. With the increase of concentration, the proliferation ability of MSCs was weakened. Conclusion 5-Aza affects the expression of regulatory gene to the stem cells and regulate MSCs to orientationally differentiate into myotube-like cells.

Objective To investigate the correlation between brain natriuretic peptide(BNP)and left ventricular diastolic function in the elderly patients with diabetes mellitus and hypertension.Methods 128 elderly patients with diabetes mellitus were divided into diabetes without hypertension (n=63)and with hypertension(n=65),and other 62 normal subjects were selected as control group.Plasma BNP levels and indexes of echocardiography,including left ventricular mass index(LVMI),the mitral peak flow velocity during early(E)and late diastole(A),ratio of E/A,average peak velocities at mitral annuluses of six sites in left ventricular wall during early(MEm)and late diastole (MAm),and relative E/MEm were measured in all patients.Results LVMI,E/MEm and the levels of BNP were significantly higher in groups of diabetes without and with hypertension[(91.6 ±17.3)g/m2 and(116.7±20.5)g/m2,(10.3±1.8)and(12.5±1.4),(47.7±29.4)ng/L and(105.7±32.5)ng/L]than in control group[(78.7±19.5)g/m2,(8.9± 1.6)and(20.8±11.63)ng/L,respectively](F=11.54,13.83 and 9.75,all P<0.05),while MEm in two diabetes groups[(6.8±1.0)and(5.4±0.9)cm/s]were decreased as compared with control group[(8.0± 1.1)cm/s,F=11.26,P<0.05].The BNP levels were negatively correlated with E/A and MEm(r =-0.42 and -0.51,all P<0.01),and positively correlated with LVMI and E/MEm(r=0.48 and 0.58,all P<0.01).Conclusions Left ventricular diastolic function is impaired in diabetes mellitus and more severely impaired in diabetic patients with hypertension.A combination of plasma BNP and echocardiography parameter may be helpful to accurately evaluate left ventricular diastolic function in the elderly patients with diabetes mellitus and hypertension.

OBJECTIVE To investigate the influence of short hairpin RNA targeting human telomerase reverse transcriptase(hTERT)on inhibition of telomerase activity and on expression of protein c-myc in nasopharyngeal carcinoma cells. METHODS Plasmid shRNA1 containing fluorescein gene and hTERT cDNA sequences were synthesized. Cells were transfected with plasmid shRNA1. The cell viability was examined using the MTT assay. The activity of telomerase was tested by polymerase chain reaction telomeric repeat amplification protocol- enzyme-linked immunosorbent assay (PCR-TRAP- ELISA),protein c-myc expression was tested by western blot. RESULTS It was observed that treatment with pshRNA1 in the presence of a valid transfection reagent could significantly reduce telomerase activity and the expression of protein of c-myc. CONCLUSION Inhibition of telomerase activity or expression of hTERT mRNA in nasopharyngeal carcinoma cells could inhibit cells proliferation and reduce the expression of protein of c-myc.
