Objective To study the characteristics of inhibition on hemozoin formation by chloroquine under in vitro condition.Methods Under different concentrations(0.5-2 mol/L) of sodium acetate(NaAc) and at the pH range of 4.0-5.0, chloroquine was tested for inhibition of ?-hematin(hemozion) formation by using the HPIA(heme polymerization inhibitory activity) assay.The morphology of ?-hematin crystals was determined by light microscopy.Ultraviolet spectrophotometry was employed to measure ?-hematin content, and the size of ?-hematin crystal was analyzed by X-ray diffraction(XRD) .Results Chloroquine exhibited varied effect on ?-hematin formation, depending on pH value and Na+ concentration.When the NaAc concentration increased from 0.5 mol/L(pH 4.2) to 2 mol/L(pH 4.8), the chloroquine inhibitory effect also increased.Results suggested that there exists a threshold pH, below which the ?-hematin formation escalates and chloroquine inhibition declines, and at or above which chloroquine exerts a stronger inhibitory effect on ?-hematin formation.With the increase of pH from 4.4 to 4.8, the crystallinity and the size of crystal changed from 6.93% and 357  to 6.32% and 264 , respectively.When pH reached to 5, no more ?-hematin formed.Chloroquine could reduce the crystallinity and crystal size of ?-hematin at same pH value.Morphology analysis on the samples was consistent with the above results.Conclusion Chloroquine inhibits hemozoin formation only when the pH value is at or above threshold pH.

Objective To explore the association of physical and mental health with coping and defensive style in asthma patients. Methods 190 adult patients with asthma were investigated with trait coping style questionnaire, defensive style questionnaire and short form 36 health survey questionnaire. Results The scores in group with higher score of health status were lower than those in group with lower score of health status in negative coping style, immature and middle defensive style, but higher in positive coping style (P

Objective To study the role of coping styles in the relationship between coping resources and psychosomatic health in patients with asthma. Methods 184 adult patients with asthma were investigated with General Serf-Efficacy Scale (GSES), Internality, Powerful Others, and Chance Scale (IPC), Social Support Rat-ing Scale (SSRS), Defensive Style Questionnaire (DSQ), Trait Coping Style Questionnaire (TCSQ) and Short Form 36 Health Survey Questionnaire (SF-36). Results Significant correlation between self-efficacy (r=0.356),locus of control(Ir=0.208, Pr=0.341, Cr=-0.349) ,subjective(r=0.201) and objective(r=0.189)social support, immature and middle ( r = - 0. 257 ) defensive styles and coping styles ( PCr = 0.231, NCr =-0.505 ) with Mental Component Summary (MCS) was found (all P <0.05), but Physical Component Summary (PCS) was only related to self-efficacy( r=0. 175) ,chance(r=0.150),immature(r=-0.256) and middle de-fensive Styles and negtive coping styles (all P < 0.05). PCS (t = - 5.189) and MCS (t = - 6. 758) could be predic-ted effectively by negative coping style (all P<0.01). Moreover, self-efficacy, powerful others and the use of so-cial support could had an effect on the health of patients through negative coping style. Conclusion Negative coping style could not only have a direct effect on the health of asthma patients but also be a mediator between self-efficacy, locus of control, social support and the health of patients.

Heparanase (Hpa) is the only β-D-glucuronidase of degading heparan sulfate proteoglycans in the body of mammalian.Studies have confirmed that Hpa accelerates angiogenesis in multiple physiopathological processes; however there are still a few studies about the expression and role of Hpa after cerebral ischemia.This article mainly introduces the relation between Hpa and angiogenesis after cerebral ischemia.

ObjectiveTo study the ability of response inhibition of depression.Methods30 depressed patients( depression group) and 30 healthy subjects (control group)were recruited in this study.The two groups were age,gender and education matched.All the subjects performed three visual Go/Nogo tasks using E-prime.The three Go/Nogo tasks were Happy Nogo Task(HNT),Normal Task (NT)and Sad Nogo Task (SNT).The two groups were instructed to press a button as quickly and correctly as possible when the Go trials were presented,but not to response when the Nogo trials were presented.In each task,the differences of accuracy (ACC) and response Time (RT) between the two groups were compared.Results ( 1 ) In HNT,during Go trials,ACC of depression group ( 0.85 ± 0.12 ) was higher than that of control group (0.75 ± 0.15 ) (P ＜ 0.05 ) ; during Nogo trials,ACC of depression group ( 0.91 ± 0.63 ) was lower than that of control group ( 0.95 ± 0.05 ) (P ＜ 0.05 ).(2) In NT,During Nogo trials,ACC of depression group(0.95 ± 0.04) was higher than that of control group (0.97 ± 0.03 ) (P ＜0.05 ).(3) There were no significant differences in RT between the two groups in any trails (P ＞ 0.05 ).ConclusionCompared with control group,depressed patients have a much higher recognize incline to the stimulus of sad emotion and a lower ability to complete normal response inhibition task.This is a new way to explain the depression pathogenesis mechanisms.

Objective:To evaluate the efficacy and safety of deoxyribonucleotide in intervention with solid tumor. Methods:A exper-imental study and randomized clinical trial were conducted. Experimental study part: MTT assay and S-180 sarcoma method were launched to observe whether the deoxyribonucleotide would affect the tumor growth. Clinical study part:86 patients of lung cancer, gastric cancer, colorectal cancer, liver cancer were divided into control group(n=43) and treatment group (n=43). Both group were given routine therapy,and the treatment group were given deoxyribonucleotide at the same time. Bone marrow suppression and live function were assessed after chemotherapy. Results:Chemotherapy Clinical effect did not improved in Deoxyribonucleotide group (47. 5% vs 44. 9%, P>0. 05), however, theⅢ-Ⅳbone,NKcellswere improved by deoxyribonucleotide (P<0. 05). What is more, the live injury of treat-ment group were less than the control group. Conclusion:Deoxyribonucleotide can decrese the occurace rate of live injury and bone mar-row suppression.

Intestinal flora is an important component of the body and is closely related to the health of infants and toddlers.There are many hypotheses about the origin and establishment mechanism of intestinal flora, but most theories are still controversial.The intestinal flora is not static, and its biodiversity and abundance will continue to differentiate and evolve with the growth and development of nurslings.It is now believed that intestinal flora plays a variety of roles in maintaining the homeostasis of the infant's internal environment.This review summarizes the basic research on the physiology of infantile intestinal flora in recent years, to provide some reference for the development of this branch in the field of pediatrics.
