Objective To evaluate the efficacy and safety of REXEEDTM series highflux dialyzer. Methods A randomized cross-over study of 3×3 Latin square was designed based on the surface area of dialyzer membrane (1.5 m2 and 2.1 m2). Seventy-two stable maintenance hemodialysis (MHD) patients from Shanghai Renji Hospital and Ruijin Hospital were enrolled in this study for 3 consecutive weeks. REXEEDTM-15AC, 15UC, 21AC, 21UC dialyzers were used as trial group and APS-15U,BIO-HX100 dialyzers were used as control group. The clearances of urea, creatinine, phosphorus and β2-microglobulin were calculated. Adverse event and adverse reactions were recorded. Results There were significantly higher urea and creatinine clearance in 1SAC and 15UC dialyzers as compared to APS-15U dialyzer [(222.07±18.74) mi/min, (220.23±26.26) ml/min vs (199.56±14.21) ml/min; (176.73±16.41) ml/min, (175.22±25.94) ml/min vs (165.42±14.68) ml/min, all P<0.05]. There were significantly higher urea, creatinine and β2-microglobulin clearance in 21AC and 21UC dialyzer as compared to BIO-HX100 dialyzer [(230.59±15.24) ml/min, (233.96±7.06) ml/min vs (203.43±36.66) ml/min; (183.50±25.90) ml/min, (181.05±23.94) ml/min vs (166.25±29.82) ml/min; (111.77±53.42) ml/min, (125.54±51.99) ml/min vs (42.39±4.81) ml/min; all P<0.05]. There was no significant difference of phosphorus clearance between REXEEDTM series dialyzers and control dialyzers. The efficiency of urea clearance and urea reduction ratio could achieve clinical targets in REXEEDTM series. Conclusion REXEEDTM series highflux dialyzers are effective and safe for clinical application.

Objective To observe expression and location of cannabinoid receptor 1 (CB1) in liver tissue of patients with chronic hepatitis B (CHB) ,and analyze the relationship of it with the liver fibrosis score,the serum levels of TGF-β1 and Leptin. Methods Liver biopsies were performed in 118 patients with CHB.The expression of CB1 in liver tissue was observed by immune histochemical staining, and semi-quantitative analysis was carried out to devide the CB1 score into four grades: -, +, + +, + + +. Serum levels of TGF-β1 and Leptin were determined by ABC-ELISA double-antibody sandwich method. Results The expression of CB1 in liver tissue with CHB had significant relationship with the fibrosis score. As the expression of the CB1 increased, the fibrosis score became higher ( F = 23. 369,P = 0. 000). Moreover, the expression of CB1 in liver tissue with CHB had significant relationship with the serum levels of TGF-β1 and Leptin( F values were 8. 762 and 5. 749;P values were 0. 001 and 0. 027, respectively). Conclusion CB1 may play promotive role in the process of hepatic fibrosis through regulation of TGF-β1 and Leptin.

Incidence of twin pregnancies increases significantly in recent years. Twin pregnancies are likely to have a higher risk of quicker progression and more severe preeclampsia (PE) than singletons, making the prediction and prevention of PE of twin pregnancies even more important. The prediction and screening for PE have evolved from guideline-based risk factor screening to simple models with maternal factors only, and then to complex models with a wider range of indicators. Besides, the modeling algorithms have expanded from logistic regression to complex algorithms such as competing risk models. Continuous improvements have been achieved in the prediction models. This paper presents a comprehensive overview of the applicability and the prospect of these models in this area in twin pregnancies and suggests that the prediction models should be improved by optimizing modeling strategies using localized indicators.

Objective To evaluate the efficacy and safety of motherwort (herbs leonuri/leonurus heterophyllus sweet) injection for preventing postpartum hemorrhage after caesarian section. Methods The prospective study was designed as a randomized and single blind multi-center research matched with positive agent as controls from Apt 2007 to Aug 2007. 440 women underwent caesarian section (CS) indicated by obstetric factors were enrolled from 15 teaching hospitals in China and assigned into three groups: group of motherwort: 147 cases were administered by motherwort 40 rag uterine injection during CS and 20 mg intramuscular injection per 12 hours 3 times after CS; group of motherwort + oxytocin : 144 cases were administered by motherwort 40 mg and oxytocin 10 U uterine injection during CS and motherwort 20 mg intramuscular injection per 12 hours 3 times after CS and group of oxytocin: 149 cases were administered by oxytocin 10 U uterine injection and oxytocin 10 U + 5% glucose 500 nd intravenously injection during operation and oxytocin 10 U intramuscular injection per 12 hours 3 times after CS. The following clinical parameter were collected and analyzed: (1) The amount of blood loss during operation, at 2, 6, 12, 24, 48 hours after operation. (2) The total amount of blood loss in 24 hours after CS and the incidence of postpartum hemorrhage. (3) The change of level of hemoglobin (Hb) and counting of red blood cell ( RBC ) from prepartum to postpartum. (4) Adverse reaction. Results (1) The mean amount of blood loss during operation were (368±258) ml in group of motherwort, (255±114) mi in group of motherwort + oxytocinand (269±141 ) ml in group of oxytocin, which exhibited significant difference among three groups ( P<0.01 ). Meanwhile, no statistical different amount of blood loss among three groups were observed at 2,6,12, 24, 48 hours after CS. (2)The amount of blood loss of postpartum at 24 hours were (480±276)ml ingroup of motherwort, (361±179) ml in group of motherwort + oxytocin, (381±179) nd in group of oxytocin, which showed significant difference among 3 groups(P <0.01 ). (3) The incidence of postpartum hemorrhage were 32.0% (47/147) in group of motherwort, 11.1% (16/144) in group of motherwort + oxytocin, and 18.8% in (28/149) in group of oxytocin. When comparing the lowest rate of postpartum blood loss in group of motherwort + oxytocin and the highest rate in group of motherwort, it displayed statistical difference (P<0.01). (4) The decreased level of RBC and Hb were shown that RBC(0.3±0.5)×10<'12<‘/L and Hb(9±13)g/L in group of motherwort, RBC (0.2±0.4)×10<'12/L and Hb ( 6±10) g/Lin group of motherwort + oxytocin and RBC (0.2±0.4)×10<'12/L and Hb(7±30) g/L in group of oxytocinrespectively. However, the comparison of different value of RBC and lib in group of oxytocin and motherwort +oxytocin showed significant difference (P<0.05 ). (5) Two cases with allery reaction was observed.Conclusion It is safe and efficacious that combined use of motherwort injection and oxytocin was to preventpostpartum hemorrhage during or after caesarian section.
