Chinese Journal of Ultrasonography 2010;19(12):1030-1034
Objective To assess global systolic function of left ventricle (LV) using speckle tracking echocardiography in patients who are left volumetric overload and to establish the correlativity between strain and left ventricle end-diastolic volume index (LVEDVI). Methods Seventy-seven patients who were left volumetric overload and 30 normal volunteers were enrolled in this study. Respective 3 high frame rate (> 100 frames/s) 2D images were recorded from the left ventricular short axis views: the levels of mitral valve annulus, papillary muscle and apex. Three global peak systolic radical strain and strain rate were measured using 2D strain imagirg. LVEDV was obtained by two-plane Simpson method and LVEDVI was obtained by normalized LVEDV with surface body area. Patients were divided into 6 groups: transitionalgroup,group A (LVEDVI:90- 120 ml/m2),group B (LVEDVI: 121 - 150 ml/m2 ),group C (LVEDVI:151 -180 ml/m2),group D (LVEDVI: 181 - 210 ml/m2),and group E (LVEDVI>210 ml/m2). Patients were divided into two groups by left ventricular ejection fraction (LVEF): group Ⅰ (LVEF≥ 50 % ), group Ⅱ (LVEF<50%). Results①Compared with normal control group,GRS,GRSr in transitional group showed no change at three short axis levels (P >0.05). The above parameters in group A, B and C were significantly higher than those in normal control group( P <0. 01 ). In transitional group,group A,B and C,GRS, GRSr of three short axis gradually increased with LVEDVI augmentation. Compared with group A, B,C,D and normal control group,the above parameters of 3 short aixs in group E were decreased( P <0. 01 ),which gradually decreased in group C, D, E with LVEDVI augmentation. ②GRS,GRSr of 3 short axis views in group Ⅰ were more significantly high than those in group Ⅱ and normal control group. The parameters above were significantly low in group Ⅱ ( P <0.01). ③In group A,B,C,GRS of papillary muscle and apex levels were correlated positively to LVEDVI ( rpapillary muscle = 0.55,0.64,0.76 and rspex = 0. 74, 0. 79,0.71,P <0.05) ; In group D, there was no correlativity between GRS of papillary muscle and LVEDVI( r =- 0.35, P > 0.05) while negative correlativity was established in apex level( r = - 0.73, P < 0. 05). In group E,the negative correlativity was found between GRS of papillary muscle and LVEDVI( r = -0. 70,P <0.05) while no correlativity was established in apex level( r = - 0.39, P >0. 05). GRS of mitral valve annulus was correlated positively to LVEDVI in group A, B( r = 0.79, 0.77, P < 0.05) and had no correlativity in group C,D. The negative correlativity between them was found in group E( r = - 0. 54, P <0.05). At LVEDVI: 180- 190 ml/m2 ,GRS of papillary muscle and apex level reach the peak point about 93% and 62% ;GRS of mitral valve annulus level reach the peak about 63% at LVEDVI 150 - 160 ml/m2.Conclusions Radial strain,strain rate change periodically with LV volume overload. Wall motion of left ventricle can be evaluated accurately by speckle tracking echocardiography, which provide useful modality for evaluation cardiac systolic function.

7.Research Progress on Chloroquine Resistance in Plasmodium falciparum and Resistance Reversal Agent
Chinese Journal of Parasitology and Parasitic Diseases 1987;0(02):-
Emergence and broad spread of chloroquine resistance urge human beings to change drug policy in malaria control and to find more effective new drugs. Nevertheless, chloroquine is still used in the treatment of falciparum malaria in some poor endemic regions due to economic and development reasons. It should be of great significance to un-derstand the mechanism of chloroquine resistance and find the way to reverse it in order to bring chloroquine with high efficacy and low cost back to the first line of the combat to malaria. Advent and development of resistance reversal agents provide a new clue for this purpose. When used together with chloroquine, it can partly restore the efficacy of chloroquine in resistant Plasmodium falciparum. The article summarizes the research progress on chloroquine resistance in P. falciparum and resistance reversers.

Chinese Journal of Parasitology and Parasitic Diseases 1997;0(05):-
Objective To study the potentiation of chloroquine activity and mechanism by ketotifen and cyproheptadine in in vitro cultured Plasmodium falciparum Fcc SM1/yN strain. Methods In vitro cultured Fcc SM1/yN strain was added to pre-prepared drug plates at 50 ?l/well after synchronization to make final concentration of 0.312 5-2 560 nmol/L for chloroqine and of 9.80-5 000 nmol/L for ketotifen or cyproheptadine. After 34 hours' culture in 37 ℃, the number of schizonts with 3 or more nuclei was calculated among 200 parasites under microscope. Calculated half inhibitive concentration ( IC50 ) of chloroquine and every drug combination to parasite as well as chloroquine activity enhancement index ( AEI) of ketotifen (or cyproheptadin) . Time dependency of potentiation was studied. All data were analyzed statistically with SPSS 13.0. After 20 hours' action of one optimal combination dose of chloroquine/ketotifen or chloroquine/cyproheptadine, RNA of the Fcc SM1/yN strain was extracted and real-time PCR was used to determine the expression level of pfcrt and pfmdr1 genes. Results The best potentiation effect was observed with ketotifen or cyproheptadine of 625 nmol/L, with IC50 of 74.53 nmol/L for chloroquine/ketotifen and 89.7 nmol/L for chloroquine/cyproheptadine respectively, and activity enhancement index (AEI) of 0.42 for chloroquine/ketotifen and 0.30 for chloroquine/cyproheptadine respectively. Combination of 625 nmol/Lketotifen or cyproheptadine with 5 nmol/L chloroquine showed the highest potentiation potency. 6-7 hours during which ketotifen or cyproheptadine was added after chloroquine showed the highest effect, with IC50 of 67.70 nmol/L for chloroquine/ketotifen and 81.53 nmol/L for chloroquine/cyproheptadine respectively, and the AEI was 0.47 for chloroquine/ketotifen and 0.37 for chloroquine/cyproheptadine respectively. After action of chloroquine/ketotifen or chloroquine/ cyproheptadine at one optimal combination dose, expression level of pfcrt gene increased by 91% and that of pfmdr1 gene decreased by 14% respectively. Conclusion Appropriate combination of chloroquine/ketotiphen or chloroquine/ cyproheptadine potentiates chloroquine against in vitro cultured P. falciparum. 6-7 hour period is an optimal time when ketotifen or cyproheptadine was added after chloroquine. Potentiating activity of ketotifen and cyproheptadine may be related to the expression level of pfcr t and pfmdr1 genes.
