1.Progress in the pathogenesis of rotavirus-associated disease
International Journal of Pediatrics 2010;37(3):232-234
Rotavirus is the most common pathogens of diarrheal diseases in children. Rotavirus infection lead to not only gastrointestinal symptoms but also a variety of extraintesu'nal manifestations. The pathogenesis of RV diarrhea and especially RV viremia is related to multiple factors. Rotavirus infectious diarrhea is related to the damaged cell intercellular connections,the non-structural protein 4, heat shock protein hsc70 and other factors. Pathogenesis of RV viremia may be related to the secretion of inflammatory mediators in vivo and expression of cytokines after RV infection.

5.Termination of pregnancy with absent end-diastolic velocity in umbilical artery
Chinese Journal of Perinatal Medicine 2012;15(4):228-233
Objective To investigate the relationship between absent end-diastolic velocity (AEDV) in umbilical artery and perinatal outcome,and to explore the effect of termination time of pregnancy on perinatal outcome. Methods Data of thirty five pregnant women with AEDV admitted into Beijing Obstetrics and Gynecology Hospital from January 2008 to December 2009 were retrospectively analyzed.According to gestational age and treatment,they were divided into four groups.Group 1:AEDV was identified before 28 weeks without treatment (n=5); Group 2:AEDV was found before 28 weeks,and then was treated (n=13); Group 3:AEDV was found after 28 weeks,and was not treated (n=11); Group 4:AEDV was found after 28 weeks,and then was treated (n=6). Except for three patients in Group 2,all patients had complications.Data were presented by frequency,rate or mean±SD. Results Among the 35 patients,19 (54.3%) delivered and 23 living children were born.When AEDV was found,the gestational age was less than 28 weeks and the mean gestational age was (22.8 ± 2.2) weeks in Group 1,(24.2 ± 2.0) weeks in Group 2,however,the gestational age was over 28 weeks and the mean value was (30.9± 2.8) weeks in Group 3 and (29.5±0.8) weeks in Group 4.Treatment was given to women in Groups 2 and 4,but not in Group 1 and 3.In Group 1,one patient complicated with twin-twin transfusion syndrome; one with hemolysis,elevated liver enzymes and low platelet syndrome and placental abruption; three recovered after two weeks and babies survived.In Group 2,the termination time was (31.4 ± 5.5)gestational weeks and the duration of treatment was (10.7± 5.5) days.AEDV of six patients were not improved after treatment,among which five accepted induced abortion,one had preterm delivery.The rest six women underwent cesarean section and one term delivered.Babies survived except for one preterm neonate and one lost in follow-up.In Group 3,the termination time was (31.2 ± 2.9)gestational weeks.Five patients accepted artificial abortion for severe complications of mother or babies; the other six patients accepted cesarean section,among which one complicated with placental abruption and baby died.The rest five babies survived.In Group 4,the pregnancies were terminated at an average of (32.8±2.9) gestational weeks and the duration of treatment was (10.8±6.7) days.Two accepted induction after treatment and four recovered to normal after treatment and accepted cesarean section with four wellbeing babies. Conclusions Perinatal outcomes of patients with AEDV complicated with severe complications after active treatment might relate to the termination time.Some patients with AEDV without severe complications might recover spontaneously with good prognosis.

8.Research Progress on the Action of Praziquantel on Voltage-gated Ca~(2+) Channel in Schistosomes
Chinese Journal of Parasitology and Parasitic Diseases 1987;0(01):-
Pharmacological actions of praziquantel against schistosome adult worms are thought to be directly linked to the disruption of Ca2+ homeostasis. The voltage-gated Ca2+ channel is an important factor in regulating the intracellular Ca2+ level. Studies have revealed that Ca2+ channel subunits may be the target for the action of praziquantel. This review summarizes the progress on the structure and function of the Ca2+ channel of Schistosoma spp and other Platyhelminths as well as the role of Ca2+ channel in action of praziquantel.
