Objective To study the effect of pravastatin on cardiac function and serum C-reactive protein (CRP) levels in patients with chronic heart failure (CHF). Methods 90 patients with CHF were randomly divided into pravastatin group (n=45) and control group (n=45). Pravastatin 40mg/d was administered in addition to the routine treatment for pravastatin group; the control group was received the routine treatment. All patients with CHF were examined serum CRP levels, LVEF at pretherapy and 3 months by ultrasonic cardiogram. Results At 3 months C-reactive protein levels were degraded in varying degree, and the serum CRP levels in pravastatin group was significantly lower than that in control group [(15.47±9.83)mg/L vs (20.31±7.15)mg/L](P<0.05), LVEF was significantly higher than that in control group[(45.70±7.01)% vs (38.34±5.31)%](P<0.05); the serum CRP levels was positively related to LVEF (r=-0.495,P<0.05). Conclusion Pravastatin may improve the prognosis in patients with CHF, and can be used as a sensitive index for pravastatin treatment of CHF.

Objective To study the efficacy of voice therapy combined with Jinsangsanjie pill in patients with vocal nodule .Methods A total of 146 patients with vocal nodes were randomly divided into three groups :45 cases in group A(single Jinsangsanjie pill therapy) ,47 cases in group B(single voice therapy) and 54 cases in group C(voice therapy combined with Jinsangsanjie pill therapy) ,30 healthy adults were as a normal control group .The treatment lasted 1 month .The results were evaluated by voice handicap index ,voice acoustic analysis and electronic laryngo‐scope which were collected before and after 1 month treatments .Results The VHI ,jitter ,shimmer and NNE of all patients were reduced while the MPT was increased after the treatment .The differences were significant (P<0 .05) .VHI 3 .64 ± 2 .12 ,jitter 0 .30% ± 0 .08% ,shimmer 1 .41% ± 0 .31% ,NNE -16 .83 ± 5 .84 dB of group C were significantly lower while MPT 18 .87 ± 3 .38 s and cure rate(93 .5% ) were significantly higher than those of in groupA(7.39±2.56,0.38% ±0.12% ,1.78% ±0.41% ,-13.38±4.42dB,16.38±3.11s,80.5% )andgroupB (23.6±12.5,0.48% ±0.18% ,1.98% ±0.42% ,-9.42±3.82dB,14.98±3.28s,52.4% )(P< 0.05).The VHI ,,jitter shimmer ,NNE of group A were significantly lower .MPT and cure rate were significantly higher than those of in group B .There were no statistical differences in each vocal indicators between group C and the normal control group (P>0 .05) .Conclusion The voice therapy combined with Jinsangsanjie pill in the treatment of vocal nodules is more efficiently ,and can improve patient’s pronunciation features .

Aim To study the inhibitory effect of ginkgolide B (BN52021) on the PAF induced changes of chemotaxis of murine peritoneal macrophages and the related polymerization of F-actin.Methods Chemotaxis assays were performed using a modified 48-well Boyden chamber. Actin polymerization of murine peritoneal macrophages was analyzed by flow cytometry using a specific fluorescent stain. Results Peritoneal macrophages significantly migrated toward platelet-activating factor(PAF) through a micropore filter; however, in the presence of PAF receptor antagonist BN52021 (0. 01the actin polymerization of murine peritoneal macrophages induced by PAF in the presence of Ca2+ , but not in Ca2+ -free medium. Conclusion The results suggested that preventing polymerization of F-actin may be a pathway by BN52021 to inhibit the chemotaxis of macrophages, and this effect seems to be Ca2+dependent. The data further indicated that inhibition of PAF induced macrophage chemotaxis is an important mechanism underlying the anti-inflammatory action of BN52021.
