Objective To investigate the efficacy and safety of polyethersulfone highlux dialyzer for maintenance hemodialysis patients. Methods Thirty-six maintenance hemodialysis patients were randomizedresigned into two groups,polyethersulfone 14HF(PES-14HF)group and polyethersulfone 150DS(PES-150DS)group,based on a random number table. The patients from two groups received different dialyzer hemodialysis for over 3.5 hours/each time respectively. Changes of serum creatinine,urea,β2-microglobulin,hemoglobin and albumin levels were measured for determination of the efficacy and safety evaluation. Results In the comparison between before or after hemodialysis,the level of serum creatinine,urea,β2-microglobulin levels decreased significantly to(333.8 ± 89. 5)μmol/L,(7. 0 ± 1.9)mmol/L,(22. 9 ± 1.7)mmol/L from(990. 2 ± 191.2)μmol/L,(24. 7 ± 4. 1)mmol/L,(13.6 ± 3.3)mmol/L respectively in the PES1 4 HF group(P ＜ 0.01);the level of serum creatinine,urea,β2-microglobulin levels decreased significantly to(395.5 ± 86.1)μmol/L,(8. 1± 2. 8)mnol/L,(18.0 ± 3.0)mmol/L from(1059. 5 ± 179. 4)μmol/L,(25.3 ± 4. 8)mmol/L,(22. 3 ± 2. 9)mmol/L respectively in the PES-150DS group(P ＜ 0. 01). We found no significant differences in each measured index between two types of hemodialysis(P ＞ 0. 05 respectively),while the level of β2 -microglobulin levels decreased more significantly in the PES14HF group(42. 81 ± 12. 48)mg/L than PES-150DS group(24. 21 ± 13. 24)mg/L(P =0. 017). Conclusions The efficacy and safety of the PES-14HF hollow fiber membrane hemodialyzer is equivalent to that of the PES-150DS hemodialyzer in hemodialysis for uremic patients.

OBJECTIVE: To study the chemical constituents of different solvent extracts from Fructus Trichosanthis, and to study their antioxidant activity and protection of myocardial ischemia reperfusion injury in rats. METHODS: The chemical constituents in different solvent extracts were determined by UV-Vis spectrophotometry. Myocardial ischemia reperfusion model was made by ligation of left coronary artery in rats. Rats were randomly divided into 6 groups, with 6 rats in each group. The sham operation group and the model groups were respectively given normal saline, Fructus Trichosanthis (equivalent to crude drug 22.5 g·kg-1), compound Danshen dripping pill group(0.085 g·kg-1). Medicines were given once a day for 7 d. After the last drug 1 h, left coronary artery was ligated for 30 min and then reperfusion was established for 120 min by removing the ligation. During this time, ECG was recorded. At the end, animals were euthanized. Blood was collected to evaluate the contents of CK-MB, MYO-MB, cTnT. The heart was removed and fixed to observe the changes of myocardial tissue by optical microscope. RESULTS: Compared with the water extract group and the alcohol extract group of Fructus Trichosanthis, the total amino acids content of Fructus Trichosanthis dichloromethane extract was not detected, but the content of total flavonoids is higher (P < 0.01). Compared with the water extraction liquid of Fructus Trichosanthis, the antioxidant properties on DPPH radical of Fructus Trichosanthis dichloromethane extract group is lower (P < 0.01), and the antioxidant activity on-OH free radical of the alcohol extract of Fructus Trichosanthis group is lower (P < 0.01). Compared with model group, the elevation of ST segment of electrocardiogram was significantly suppressed in each group during reperfusion (P < 0.01 or P < 0.05). The plasma CK-MB, cTnT and MYO-MB in water extract group were significant lowered (P < 0.05). CONCLUSION: The extraction of Fructus Trichosanthis is able to decrease the production of oxidants. The water extract of Fructus Trichosanthis could ameliorate myocardial ischemia reperfusion injury.
