Objective To analyze the influence of hyponatremia on hospitalization days and hospital mortality of hospitalized patients with chronic heart failure. Methods All data were collected from 2465 patients with chronic heart failure in our hospital between January 1980 and August 2007. According to the admission serum sodium, all the patients were divided into two groups: low serum sodium group (Na+<135 mmol/L) and normal serum sodium group (Na+≥135retool/L). Clinical characteristics, therapeutic conditions and the influence of hyponatremia on prognosis were analyzed between the two groups. Results There were 618 patients in low serum sodium group among 2465 cases. Patients with hyponatremia were more likely to have lower systolic blood pressure and lower left ventricular ejection fraction. Lower admission serum sodium was related with higher concentration of serum angiotensin, aldosterone and higher activity of serum renin. Patients in low serum sodium group had significantly longer hospitalization days (Z=-4.026, P<0.01) and higher rate of hospital mortality (χ2=76.935, P<0.01) than patients in normal serum sodium group. Multivariate logistic regression indicated that lower admission serum sodium was an independent risk factor for hospitalization days (b= 0.928, P<0.01) and hospital mortality (OR=0.928, P<0.01). There was a negative correlation between admission serum sodium and hospitalization days (r=-0.132, P<0.01), and the rate of hospital mortality increased by 24.7for each 3 mmol/L decrease in admission serum sodium level. Conclusions Hyponatremia in hospitalized patients with chronic heart failure is relatively common and is associated with poorer heart function, higher activity of neural hormone and more severe prognosis. It is important to prevent hyponatremia for shortening hospitalization days and improving the prognosis of patients with chronic heart failure.

OBJECTIVE:To investigate the effects of simvastatin intensive treatment on the Postoperative Related Indexes of patients with acute coronary syndrome(ACS) underwent percutaneous coronary intervention(PCI). METHODS:106 patients with were included in the study and randomly divided into observation group(53 cases)and control group(53 cases). Both groups were given aspirin 100 mg,qd+clopidogrel 75 mg,qd before PCI for 4 weeks;observation group was additionally given Simvastatin tablet orally 20 mg before supper 15 d before surgery. TC,TG,LDL-C,HDL-C,hs-CRP,IL-6 and IL-18 levels,LVEF,the occurrence of coronary artery restenosis were detected in 2 groups before surgery and 6 months after surgery. The occurrence of ADR was recorded during treatment. RESULTS:There was no statistical significance in the levels of TG,TC,LDL-C and HDL-C between 2 groups before surgery and 6 months after surgery (P>0.05). There was no statistical significance in hs-CRP,IL-18, IL-6 and LVEF levels between 2 groups before surgery(P>0.05). 6 months after surgery,hs-CRP,IL-6,IL-18 and LVEF levels of 2 groups were significantly higher than before treatment;hs-CRP,IL-6 and IL-18 levels of observation group were significantly lower than those of control group,and LVEF was significantly higher than control group,with statistical significance (P<0.05). The incidence of coronary artery restenosis in observation group was significantly lower than control group, with statistical significance (P<0.05). No ADR was found in 2 groups during treatment. CONCLUSIONS:Preoperative simvastatin intensive treatment can effectively reduce cardiovascular inflammation degree in patients with ACS after PCI,prevent the formation of coronary artery thrombus,and reduce the incidence of coronary artery restenosis so as to effectively improve the prognosis and don' t increase the incidence of ADR.

Objective To understand the effect of anti-cysticercus therapy for patients with cerebral cysticercosis and the changes of cysticercus on CT image after treatment. Methods The patients with cerebral cysticercosis were classified by the presentation of their brain CT image before treatment, then the effect of anti-cysticercus therapy on them after treatment was analyzed and the presentations of their brain CT images between before and after treatment were compared. Results There were different changes on CT image of cysticercus in brain tissues after anti-cysticercus therapy for different types of patients with cerebral cysticercosis. Type Ⅰ: the focus was absorbed completely after treatment in the majority of patients and calcificated in the minority. Almost all the patients were cured clinically after anticysticercus therapy. Type Ⅱ: the focus was absorbed completely in the minority, and one to two or more calcification dots were observed in the majority of patients. Anti-cysticercus therapy was effective. Type Ⅲ and Ⅳ: the absorption of focus was not very good and the effect of anti-cysticercus therapy was lower relatively. Conclusion The changes of CT image such as absorption, calcification, has important significance in forecasting prognosis and instructing clinical usage.

ObjectiveTo explore the effect of the calcium phosphate cement (CPC) /calcium polyphosphate fiber (CPPF) composites mixed with different proportion of minimal morselized bone on repair of bone defect in vivo. MethodsA total of 36 New Zealand white rabbits were completely randomly designed into A, B, C, D groups and their bilateral radial bone defect model was prepared. The minimal morselized bone (300-500 μm in diameter) was made from the iliac of those rats. The CPPF and CPC were evenly mixed into CPC/CPPF composites which were divided into four groups in accordance with the CPPF weight O, 10%, 30% and 50% in CPC/CPPF composite. The CPC/CPPF composites of the four groups was mixed with the minimal morselized bone with ratio of 6:4 and then the mixture was implanted the bone defect of the rabbits in four groups. The gross, X-ray and histological observations were done at four and eight weeks. The biomechanical test was performed at eight weeks. Results When CPPF occupies 30% of the CPC/CPPF composite, the maximum compressive load and bending loads were better than those in the other groups ( P < 0.05 ), when the histological observation showed the most tight link between the artificial composite and the bone interface and the closest similarity between material degradation rate and the ossification rate, with the best osteogenesis and the optimal ratio.ConclusionThe repair of bone defect can attain the optimal outcome through adding a certain ratio of minimal morselized bone into the CPC/CPPF to adjust the degradation rate of composites.

OBJECTIVETo compare the efficacy and safety of 5 mg perindopril arginine salt and 4 mg perindopril tert-butylamine salt for patients with mild to moderate essential hypertension.
METHODSThe study was designed as multicenter, randomized, double-blind, active controlled trial with two parallel groups enrolling 524 participants with mild to moderate essential hypertension. After 2-week run-in period, 186 patients were enrolled and randomly treated with 5 mg perindopril arginine salt and 183 patients were enrolled and randomly treated with 4 mg perindopril tert-butylamine salt. The random sequence was generated by the I.R.I.S., and a balance was made in each center. After double-blind treatment for 8 weeks, the dose could be doubled for patients with uncontrolled BP ((SBP) ≥ 140 mmHg (1 mmHg = 0.133 kPa) or diastolic blood pressure (DBP) ≥ 90 mmHg) and patients were treated for another 4 weeks.
RESULTSThe sitting SBP was similarly decreased by (19.9 ± 17.2) mmHg in perindopril arginine group and (18.5 ± 14.7) mmHg (P = 0.000 5) in perindopril tert-butylamine group post 8 weeks treatment. Dose was doubled in 109 patients (59.9%) in perindopril arginine group and 116 patients (63.7%) in perindopril tert-butylamine group. At 12 weeks post therapy, the sitting SBP decreased by (19.8 ± 16.2) and (19.6 ± 16.3) mmHg respectively in the 2 groups. The decrease of sitting DBP was also similar in both groups (-12.0 ± 10.0) mmHg and (-11.0 ± 8.9) mmHg (P < 0.000 1), respectively. The control rate or response rate was also similar between the two groups (control rate over 8 weeks was 38.5% vs. 31.3%, 95% CI (-2.6-16.9), control rate over 12 weeks was 36.3% vs. 35.7%, 95% CI (-9.3-10.4), response rate over 8 weeks was 64.3% vs. 63.2%, 95% CI (-8.8-11.0), response rate over 12 weeks was 65.9% vs. 64.8%, 95% CI (-8.7-10.9)). Incidence of adverse events was low and similar in both therapy groups.
CONCLUSIONSThe results show that perindopril arginine salt 5 mg is as efficient as perindopril tert-butylamine 4 mg on lowering BP for patients with mild to moderate essential hypertension. Both drugs have good safety profile and are well tolerated by patients in this cohort.
