Objective A review of cases of congenital hip dislocation in high age children by Pemberton operation and accessory measures and investgate if the hip joint stiffness rate and ischemic necrosis rate of femoral head after operation are reduced. Methods From February 1987 to February 2000, 76 hip congenital dislocation of 58 high age children (7 years old to 14 years old) were treated by Pemberton operation and accessory measures, and were followed up from 2 years to 11 years(average, 5 years and 2 months). The accessory measures included: 1)traction of the leg for enough time with enough weight before operation, 2) immobilizing the leg by skin traction in neutral position and plank shoes instead of traditional plaster cast after operation, 3)early movement of the hip joint after operation and was allowed ambulatory late, 4) periodically the hip joint was mobilized passively. Results Six cases can only bend their hip joint below 90 degrees, accounting for 7.9% of all. 29 ischemic necrosis of femoral head occurred which accounted for 38.2%. The rate of ischemic necrosis of the femoral head and hip joint stiffness of high age children after operation were reduced obviously according to the standard by Salter. Conclusion Pemberton operation was preferred in treating the congenital hip dislocation of high age children. The accessory measures reduced the rate of ischemic necrosis of femoral head and hip joint stiffness.

OBJECTIVE:To compare therapeutic efficacy and safety of indapamide separately combined with benazepril,irbe-sartan or amlodipine for grade 2 essential hypertension(EH). METHODS:A total of 150 patients with grade 2 EH were randomly divided into benazepril group(50 cases),irbesartan group(50 cases)and amlodipine group(50 cases). 3 groups were given Indap-amide tablet 2.5 mg orally,once a day. Benazepril group was additionally given Benazepril hydrochloride tablet 10 mg orally,once a day;irbesartan group was additionally given Irbesartan tablet 150 mg orally,once a day;amlodipine group was additionally giv-en Amlodipine tablet 5 mg orally,once a day. 3 groups were treated for 12 weeks. The levels of systolic pressure,diastolic pres-sure,heart rate,total cholesterol(TC),three triacylglycerol(TG)and serum potassium as well as the occurrence of ADR were ob-served in 3 groups before and after treatment. RESULTS:The total response rate of berazopril group,irbesartar group and a mloelip-ire group had no significant difference(90.0% vs. 88.0% vs. 92.0%,P>0.05). There were no statistical significances in the levels of systolic pressure,diastolic pressure,heart rate,TC,TG and serum potassium among 3 groups before treatment(P>0.05). Af-ter treatment,systolic pressure and diastolic pressure of 3 groups were significantly lower than before,with statistical significance (P<0.01);but there was no statistical significance among 3 groups(P>0.05). There were no statistical significance in heart rate, TC,TG of 3 groups before and after treatment and the level of serum potassium in benazepril group and irbesartan group (P>0.05). After treatment,the level of serum potassium in amlodipine group was significantly lower than before,with statistical signifi-cance (P<0.05). The incidence of ADR in irbesartan group was significantly lower than benazepril group and amlodipine group, with statistical significance (P<0.05);but there was no statistical significance between benazepril group and amlodipine group (P>0.05). CONCLUSIONS:The indapamide separately combined with benazepril,irbesartan or amlodipine have similar therapeu-tic efficacy for grade 2 EH,but the safety of irbesartan is better than those of benazepril and amlodipine.

BACKGROUND:Poly(propylene fumarate) (PPF) can crosslink at room temperature, andβ-tricalcium phosphate (β-TCP) has good biocompatibility, but PPF/β-TCP composite bone cement has not yet been systematical y studied. OBJECTIVE:To prepare PPF/β-TCP composite bone cement and to explore its in vitro bioactivity and degradability. METHODS:β-TCP and PPF were respectively synthesized by liquid-phase precipitation and a two-step method, and PPF/β-TCP composite bone cement was prepared through mixing PPF withβ-TCP. The in vitro bioactivity of PPF/β-TCP was compared with the commercial poly(methyl methacrylate) (PMMA) through the ability of forming hydroxyapatite after immersed in simulated body fluid for 7 days. The in vitro degradability of PPF/β-TCP was studied via investigating the transformation of pH values, water uptake and mass loss, compressive strength and morphology at each time point. RESULTS AND CONCLUSION:There were hydroxyapatites formed on the PPF/β-TCP material, but none on the commercial PMMA material. The pH values of the PPF/β-TCP were stable in PBS for 63 days, indicating its degradation is moderate;the mass loss was up to 13.5%after 84 days. Scanning electron microscope displayed the degraded PPF/β-TCP surface, and its compressive strength was decreased gradual y, which good for the integrity and sustainability of mechanical properties during degradation. These results suggest that PPF/β-TCP bone cement holds mineralization and degradability in vitro.
