In order to confirm the hypothesis that during acute hypoxia, the antiarrhythmic peptide (AAP10) could improve conductance by changing the phosphorylation state of connexin43 (Cx43), isolated perfused rat hearts were randomly divided into three groups: control, hypoxia and AAP10 (n=9 in each group). The change in Cx43 phosphorylation was tested by Western-blot; the distribution of Cx43 was observed by confocal immunofluorescence microscopy. Western-blot analysis revealed that the expression of total Cx43 protein was significantly decreased during acute hypoxia, while nonphosphorylated Cx43 (NP-Cx43) was unchanged. AAP10 could increase the expression of total Cx43 protein, but had no effects on the NP-Cx43 protein. Immunofluorescence study showed that during acute hypoxia, both total Cx43 and NP-Cx43 proteins were greatly decreased, while AAP10 only increased the expression of total Cx43 protein, but had no effect of the NP-Cx43 protein expression. These findings suggested that the decrease of intercellular communication may be associated with the reduction of phosphorylated Cx43 (p-Cx43) and translocation of NP-Cx43 from the surface of gap junction into intracellular pools during acute hypoxia. AAP10 can improve intercellular communication by enhancing phosphorylation of Cx43.

Objective To explore the effect of astragalus injection with heparin in treatment of children with nephrotic syndrome(NS) whose blood was high coagulable.Methods Seventy-two children suffering from NS, whose blood was high coagulable,were randomly divi-ded into 2 groups. The suffering children of 2 groups were given diuretic and anti-infective and hypotenive drugs, simultaneously taking prednisone 2 mg/( kg?d). In addition, the suffering children of therapeutic group was given astragalus injection 20 mL and heparin 100 IU/kg which were added in the glucose injection 200 mL absorbed by intravenous drop.They had blood test since they had taken the medicine once a day and maintained 2-4 weeks′ time.Results The suffering children′s PLT,febrinogen(Fbg) and prothrombin time(PT) of therapeutic group were all lowered down to normal quantity in 10 days but those of contrastive group in 2 weeks or more. The time of urinary protein′s vani-shing of the therapeutic group averages out to (8.9?4.1) d;but contrastive group became normal after 2 weeks and urinary albumen disa-ppeared in (12.8?6.2) d.Conclusions The astragalus injection with heparin is significant to shortening the course of treatment and redu-cing the relapse and preventing from thrombosis in the treatment of NS of suffering children whose blood is high coagulable.The treatment of anti-coagulation can be one of conventional plans.

Objective To explore the relationship between ULI43 sequence variability and clini-cal disease. Methods UL143 from samples obtained from suspected congenitally human cytomegalovirus (HCMV) infected symptomatic infants were PCR amplified and sequenced. Results There were not too much sequence variability of UL143 compared with Toledo. But no one was completely identical to Toledo, and all UL143 ORFs were shorter than Toledo for frame-shift. Conclusion HCMV-UL143 existed in moat of low passage isolates and sequences were variable. No obvious linkage was observed between UL143 poly-morphisms and outcome of suspected congenital HCMV infection.

Objective To establish a HPLC-ELSD method for determining the content of astragaloside Ⅳ in Qingshen Jianfei Tablets. Methods Stationary phase was C_(18) column (4.6 mm?250 mm, 5 ?m), mobile phase was acetonitrice-water (35 : 65). The evaporation temperature was 120 ℃, the pulverization temperatire was 80 ℃, the flow rate was 1.6 mL/min and column temperature was 35 ℃. Results The standard curve was linear within the range of 1.03～8.24 ?g, r=0.9999. The average recovery was 99.35% with RSD = 1.36% (n = 6). Conclusion The established method is simple and accurate, with good reproducibility and high precision, and suitable for the determination of astragaloside Ⅳ in Qingshen Jianfei Tablets.
