Objective To evaluate the efficacy and safety of itraconazole injection in treatmeat of invasive fungal infections.Methods The clinical trial was conducted in 16 patients(17 times)with invasive fungal infection from August 2003 to August 2005,including 1 case confirmed,11 cases(12 times)suspected and 4 cases for empiric treatment.They were treated with iv itraconazole injection in a dose of 200 mg twice daily in the first and the second day,from the third day to 14th day they were given iv itraconazole injection in a dose of 200 mg once daily,and then treated with capsule in a dose of 200 mg twice daily for another 28 days.Two cases were treated with iv itraconazole injection in a dose of 200 mg twice daily for 9 days and 14 days;1 case in a dose of 200 mg once daily for 21 days.Results 62 strains were isolated from 16 patients with invasive fungal infection,including 40 strains in urine cultivate,and 21 strains of tropic candida were primacy.In confirmed and suspected patients,the cure rate was 6/13,the effective rate was 11/13 and the eradication rate was 6/13.The incidence of adverse reaction was 3/24.Conclusion Itraconazole injection is effective and safe in treatment of severe invasive fungal infections,especially in severe ill,old patients for long time use.

ObjectiveTo evaluate the value of 24 h dynamic electrocardiogram (DCG) and treadmill exercise testing(TET) in diagnosing coronary heart disease(CHD),and analyze relevant index between coronary arteriography(CAG) and treadmill exercise testing.MethodsOne hundred and forty-nine borderline cases of coronary heart disease were enrolled.Every patient was examined by DCG,TET,and CAG,compared the diagnostic value of TET combined with DCG and TET or DCG alone,and record the increased heart rate during the first minute( △ HRl min) of TET and systolic blood pressure(SBP) recovery.The patients were divided into a CHD group and a non-CHD group according to the results of coronary angiography.ResultsThe sensitivity rate was 78.57％ and specific rate was 70.77％ by means of TET.The sensitivity rate was 61.90％ and specific rate was 66.15％ by means of DCG.The sensitivity rate was 95.23％ ,specific rate was 55.38％,positive predictive value was 73.39％ and negative predictive value was 90.00％ by parallel way of DCG and TET,its sensitivity rate (95.23％) and negative predictive value (90.00％ ) were more than those of DCG or TET alone.The sensitivity rate was 52.38％,specific rate was 95.38％,positive predictive value was 93.62％ and negative predictive value was 60.78％ by serial way of DCG and TET,its specific rate (95.38％) and positive predictive value (93.62％ ) were more than those of DCG or TET alone.The number of men in the CHD group was higher than the number of women.Ratio of systolic blood pressure recovery(rSBPR) in the CHD group was significantly higher than that in the non-CHD group ( P ＜ 0.01 ).Conclusion It can obviously enhance the sensitivity rate and specific rate if combined TET with DCG.Patients with CHD have a delayed decline in SBP during recovery which can be one of the indexes to estimate the extent of myocardial ischemia and coronary artery lesion.

Objective To investigate the therapeutic effects of low-dose heparin on sepsis. Methods Seventy-nine sepsis patients were randomly divided into tow groups: beparin treatment group (n=37) and routine treatment group(n =42). The 7-day and 28-day mortality, the days in ICU and the length of stay, the changes of oxygenation index, the days of mechanical ventilation and the rates of disseminated intravascular coagulation (DIC), acute renal failure (ARF), acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome(MODS) were observed. The levels of APTT, PT and platelet (PLT) count were determined before and after treatment in two groups. Results The rates of DIC, ARF and MODS in beparin group decreased significantly after therapy: rate of BIC, 15.4% vs 38. 7% (P=0.03) ; rate of ARF, 25.0% vs51.9% (P=0.04); rate of MODS, 26.3% vs50.0% (P=0.04). In heparin group, the 28-day mortality was statistically reduced (15.4% vs 32.4%, P = 0. 03). The differences between beparin group and routine group were not statistically significant in the 7-day mortality (7. 7% vs 12. 9% ,P =0. 08) ,the days in ICU(Z =0. 281 ,P =0. 779,rank sum test) ,the length of stay (Z = 0. 562, P = 0. 574, rank sum test), the oxygenation index (P = 0. 82), the days of mechanical ventilation [(126.07±166.21)h vs (179.27±221.7)h,P=0.28] and the rate of ARDS (44.0% vs 46.2% ,P= 0. 88). The differences in APTT, PT and PLT were not significant between the two groups. Conclusion Low-dose beparin can decrease the mortality rate of sepsis and improve the prognosis of patients. It is a safe promising therapy in sepsis patients without severe side effects.

Objective To assess the correlation between inflammation,specific immune response and coronary heart disease(CHD). Methods Thirty healthy cases passed the health examination were taken as the control group. Eighty cases who were diagnosised into CHD,affirmed by coronary angiography,were divided into three groups: acute myocardial infarction (AMI) group(26 cases),unstable angina pectoris (UP) group (24 cases),and stable angina pectoris (SP) group(30 cases). All the cases were tested on the concentrations of C-reactive protein(CRP),IgA,IgG,IgM in serum. Results The serum indices of CRP,IgG,IgA in AMI group and UP group were significantly difference than those in the control group (P0.05). Conclusion The correlation between inflammation and immune system activation are closely associated with CHD.

Objective To approach the correlation of the left ventricular function in elderly patients with acute myocardial infarction (AMI) at low-risk factor. Methods Forty-five elderly patients hospitalized for AMI were registered, including 20 patients who were underwent emergency percutaneous coronary intervention (PCI) after the onset of AMI and 25 patients who received conservative non-invasive therapies. These 45 cases all received echocardiography(ECHO) examination in the 4th and 24th week after acute myocardial infarction. Results In the PCI group, end-diastolic volume index (EDVI) and end-systolic volume index (ESVI) had significant difference (P0.05) after therapy; WMSI was higher than PCI group (P

Objective To study the long-term effect of administration(6 months) with transient receptor potential vanilloid 1(TRPV1) agonist capsaicin on contractile reactivity of thoracic aorta in C57BL/6J mice.Methods Tow-month-old male C57BL/6J mice were received normal diet group(n=12) or capsaicin group(normal diet plus capsaicin,n=12).Tail-cuff systolic blood pressure(SBP) was examined at the baseline and at the end of the intervention.After 6-month treatment period,carotid artery blood pressure and heart rate were determined by catheterization,and the aortic contractile response was examined using isometric myograph(Danish Myotech Technology,Denmark).Plasma levels of renin,angiotensin Ⅱ(Ang Ⅱ) and aldosterone were determined.Vascular smooth muscle cells(VSMC) were obtained from thoracic aorta of mice and cultured.Angiotensin Ⅱ type 1 receptor(AT1R) protein expression was detected by western blot.Calcium imaging was detected in cultured VSMC using the fluorescent dye technique.Results Systolic blood pressure,invasive carotid artery blood pressure and heart rate have no difference between two groups.No differences was found in PE-induced contraction response in thoracic aorta;while Ang Ⅱ induced contractility of aortic ring was lower in mice with capsaicin than control group [capsaicin:(37.5?1.6)% vs(59.8?1.4)%,P

Objective To evaluate the clinical application value of multi-slice helical CT volumetric (VH) scanning in lumber spine. Methods One thousand of patients with back and leg pain who underwent CT examinations were selected as subjects. We simulated the traditional protocol of single-slice(SS) discrete scanning for L3/4, L4/5, and LS/S1 intervertebral discs. The VH scanning mode was performed with 120 kV, 210 mAs,pitch of 1.5 and coverage of 97. 5 mm. The simulated SS scanning mode was performed with 120 kV, 240 mAs and coverage of 45.0 mm. The diagnostic outcomes and the radiation doses were compared between the two scanning modes. Two groups doctors observed ten terms, including the osseous spinal stenosis,narrowed intervertebral space and so on in two scanning modes respectively. Then consistency analysis of the data was carried out. Results The VH scanning mode showed far more features than the SS mode. The detection rates of the VH mode in the osseous spinal stenosis, narrowed intervertebral space,herniated nucleus pulposus, narrowed lateral recess, vertebral lesion, hypertrophy of L5 transverse process,abnormal direction of facet, facet degeneration, lumbar spondyloschisis, and paraspinal soft tissue were 11.8% (n =118), 38. 5% (n =385), 9. 3% (n =93), 46. 8% (n =468), 31.4% (n =314), 5.7% (n =57), 25.4% (n = 254), 49. 7% (n = 497), 9.9% (n = 99), and 0. 6% (n = 6) respectively, while the detection rates of the SS mode in ten terms were 5.6% (n = 56), 0, 0. 6% (n = 6), 27. 9% (n = 279),22.4% (n =224), 1.2% (n = 12), 16.7% (n = 167), 37.2% (n =372), 0.5% (n =5), and 0.2%(n = 2) respectively. The difference between the two groups had statistically significance (average P <0.05), except the paraspinal soft tissue abnormal (P > 0.05). The detection rates of the VH mode were higher than the SS mode in the osseous spinal stenosis, narrowed intervertebral space, herniated nucleus pulposus, lumbar spondyloschisis, being 6.2% (n = 62) , 38. 5% (n = 385) , 8.7% (n = 87), and 9.4%(n =94), respectively. In addition, VH mode only partially showed the articular facets, narrowed lateral recess, hypertrophy of L.5 transverse process, and paraspinal soft tissue. We could not acquire the imaging slices paralleling to intervertebral discs in SS mode in 467 patients (46.7%) with lumbosacral angle greater than 35°. The radiation dose of VH mode (164.9 mGy/em) was slightly higher than SS mode (147.0 mGy/cm) Conclusion MSCT VH scanning mode can significantly improve the diagnostic rate of lumbar spine diseases compared with SS mode, and was not restricted by the lumbosacral angle with slightly increasing radiation dosage.
