Objective To examine the relationship between hematocrit and risk of long term mortality among patients with acute myocardial infarction. Methods A total of 274 patients with acute myocardial infarction were recruited and divided into two groups by death after long term follow-up, the relationship between hematocrit and mortality was evaluated through the methods of independent t-test,chi-square test and multivariate regression analysis. Results The mean age was 69. 79 ± 7.45 years, with 73. 0% of male. The average of followup was 44. 4± 10. 7 months, with mortality of 38.7% . Comparison of baseline data showed that NYHA classification, smoking history, hemoglobin, hematocrit, mean red cell volume, glomerular filtration rate, ejection fraction,left ventricular diastolic diameter and right ventricular diameter was significantly different between the two groups( Ps < 0. 05), Multivariable logistic analysis showed that hematocrit ,glomerular filtration rate, ejection fraction and smoking history were independently predicted factors, with OR of 0. 904 (95% CI: 0. 832 - 0. 982,P =0. 016) ,0. 983 (95% CI: 0. 969 -0. 996,P =0. 014) ,0. 932 (95% CI: 0. 887 -0. 979,P =0. 005) and 3. 230 (95% CI: 1.468 - 7. 106, P = 0. 004), respectively. The power of hematocrit to predict mortality was examined by ROC curves, the area under the curve was 0. 669(P < 0. 001,95% CI: 0. 603 - 0. 736) Conclusion Hematocrit is a significant independent predictor for long term death among patients with acute myocardial infarction.

AIM To improve the treatment efficacy of anti-tumor drug mitoxantrone, the conjugation of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies were prepared. METHODS Mitoxantrone-loaded nanospheres were prepared with emulsion-heating solidification technique. A heterobifunctional reagent, N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP), was used as the crosslinker of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies; pharmaceutical properties of immunonanocapsuls were studied; the conjugates of nanospheres and monoclonal antibodies was confirmed with immunological methods such as slide agglutination test, fluorescent immunossay and rosset formation test, fluorescent staining and scanning electron microscope. RESULTS Mitoxantrone-loaded nanospheres were spherical, with smooth surface and median diameter of 0.665 micron. When stored at 3-5, 20-25 and 37℃, RH 75% for three months, the appearance, morphology, size distribution, drug loading and in vitro release characteristics showed no significant change and the stability was satisfactory. The size analysis demonstrated that there was no obvious increase in the particle size of nanoparticles after conjugation. Immunological tests indicate highly selective binding of antibody-targeted nanospheres to C-erbB-2-overexpressing cells SK-BR-3. CONCLUSION The conjugation of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies can keep the activity of anti-C-erbB-2 and increase the therapeutic efficacy of anti-mammary cancer drugs.

OBJECTIVE:To systematically review the effectiveness and safety of methotrexate(MTX)in the treatment of rheuma-toid arthritis,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Medline,EMBase,Cochrane Library,PubMed,CJFD,CBM,VIP and Wanfang Database,randomized controlled trials(RCT)about MTX in the treatment of rheu-matoid arthritis were collected,Meta-analysis was performed after data extraction and quality evaluation. RESULTS & CONCLU-SIONS:33 effectiveness evaluation were included,involving 8 253 patients,and 53 safety evaluation were included,involving 4 803 patients. Results of analysis show,the efficacy of MTX was not higher than leflunomide in the treatment of rheumatoid arthritis,superi-or to cyclosporine A,and similar to sulfasalazine. In addition,MTX shows similar efficacy with etanercept(7.5-20 mg per week),goli-mumab,adalimumab or rituximab,but less effective than trastuzumab. The incidence of adverse reactions of MTX is high,but mainly mild or moderate,and the most common adverse reactions are gastrointestinal symptoms. Oral administration of MTX is more secure than intramuscular injection and subcutaneous injection.

Objective To investigate the feasibility and efficiency of monitoring noninvasive respiratory effort and respiratory load-capacity ratio in patients undergoing weaning from mechanical ventilation by mean inspiratory pressure(Pi) which were calculated on the basis of the formula, Pi = 5 × P 0.1 × Ti, as well as the noninvasire tension index calculated from Pi(TTIi). Method Totally 12 patients undergoing weaning from mechanical ventilation were enrolled in the study and their underlying diseases included COPD( n = 9), ARDS( n = 2) and status asthmaticus(n = 1) respectively. Esophageal pressure(PesoM) was monitored via the insertion of esophageal balloon and corrected esophageal pressure(Peso) was acquired by subtracting elastic pressure of chest wall from PesoM. P 0.1, Maximal inspiratory pressure on esophageal pressure curve(MIPeso) and on airway pressure curve(MIPaw) was measured with conventional technique. Pi was calculated on Pi = 5 × P 0.1 × Ti. Pi and MIPaw were used to calculate the noninvasive tension-time index TTIi, whereas Peso and MIPeso were used to calculate the invasive counterpart TTIeso. Comparisons, Correlation and Bland-Altman agreement analysis were made between P0.1 and Peso as well as between TIIi and TTIeso. Results There were no significant differences between Pi and Peso as well as between TTIi and TTIeso(P > 0.05) ,and the correlation coefficients were 0.974 and 0.957 respectively. In the agreement analysis, the mean difference between Pi and Peso, and between TTIi and TTIeso were lower than the minimal values of(Peso + PiSB )/2 and of(TIIi + TTIeso)/2, respectively. Conclusions There is a good correlation between Pi and Peso as well as between TTIi and TTIeso, in which Pi is calculated calculated from P 0.1 and in turn the TTIi is calculated from Pi. The noninvasive indices including Pi and TTIi can be used to monitor respiratory effort and respiratory load-capacity in patients undergoing weaning from mechanical ventilation.

Objective To explore the differences of patient comfort and nursing workload between ultrasound guidance on upper arm placement of PICC and traditional placement of PICC, and to provide a reference for correct selection of catheter way. Methods Using a nonrandomized controlled study, a total of 1 116 patients were divided into the control group and the observation group, patients with traditional placement of PICC were set as the control group, and the patients with upper arm placement of PICC were named as the observation group. The patient comfort and workload of use and maintenance of PICC by nurses were compared between two groups. Results The incidence of catheter sliding out of PICC in the observation group was 1.9%(7/365), obviously higher than that of the control group, which was 0.3%(2/751), the difference was significant (χ2=8.37,P=0.007). The patient comfort had no statistical significance between two groups (t=2.13,P=0.082). The workload of use and maintenance of PICC in the observation group were (1.87±0.31) min and (9.16±1.07) min ,which were obviously higher than that of the control group [(0.85±0.16) min and(7.22±2.13) min] in winter (t=4.39, P=0.022;t=3.44, P=0.041), but there was no statistical significance between two groups in summer (P>0.05). Conclusions The workload of use and maintenance of PICC on upper arm placement was higher than traditional placement of PICC in winter, but the obvious differences of patient comfort and nursing workload in summer between the two PICC groups were not been found.
