Objective:To explore therapeutic effect of felodipine combined atorvastatin on aged patients with isolated systolic hypertension (ISH).Methods:A total of 176 aged ISH patients were selected from our hospital from Mar 2012 to Jan 2014. They were randomly and equally divided into felodipine group (only received felodipine and other routine therapy)and combined treatment group (received atorvastatin based on treatment of felodipine group),both groups were treated for 12 weeks.Levels of systolic blood pressure (SBP),diastolic blood pressure (DBP),pulse pressure (PP),fore brachial artery endothelium dependent diastolic-systolic function (FMD),nitric oxide (NO), high sensitive C reactive protein (hsCRP)and interleukin (IL)-6 were measured and compared between two groups before and after treatment.Results:Compared with before treatment,after treatment there were significant reductions in levels of SBP,PP,hsCRP and IL-6,and significant rise in FMD and NO level in both groups (P<0.01 all).Compared with felodipine group after treatment,there were significant reductions in levels of SBP [(134.64 ±9.64)mmHg vs.(130.86±9.75)mmHg],PP [(68.57±6.01)mmHg vs.(57.84±5.79)mmHg],hsCRP [(11.94±2.95)mg/L vs.(7.47±1.97)mg/L]and IL-6 [(10.64±3.85)mg/L vs.(5.84±3.11)mg/L],and sig- nificant rise in DBP [(72.64±7.95)mmHg比 (77.94±8.13)mmHg]and FMD [(9.75±2.56)% vs.(12.54± 4.65)%]and NO [(53.74±8.65)μmol/L vs.(86.48±6.84)μmol/L]in combined treatment group,P<0.05 or<0.01. Conclusion:Felodipine combined atorvastatin possesses good therapeutic effect in aged patients with isolated systolic hypertension.It' s help to recovering vascular function and lower inflammatory reactions.

Lymphokine-osteoclast activating factor(OAF) is a potent mediator of bone resorption. PGs which mediate bone resorption are necessary for OAF. It has been reported that mononuclear is an important factor in bone resorption; and circulating monocytes may be osteoclast precursors,but it is not clear at present. We used CT and PTH which are potent physiological calcium-regulator hormones to stimulated mono-nuclear to study it's role for bone resorption. Mononuclear was isolated from normal human peripheral blood by Ficoll-Hypaque. After cultured in C02 incubator at 37℃ for 24h. 0.05g/L PTH and 100U/L CT were added and incubated in the same condation. After 2.5min, 5min, 10min, and 15min cAMP was measured by RIA. In the sam way PGE was determined. Our experiment exhibited that circulating mononuclear responds to CT and PTH with an increase in cAMP firstly, and enhances PGE production by CT and PTH stimulated mononuclear secondly. The results suggest that mononuclear participated in the regulation of bone resorption by PGE, OAF and other factor.
