Objective To evaluate the efficacy and safety of trimetazidine (TMZ) in the treatment of Stable Angina Pectoris (SAP). Methods Randomized controlled trials (RCTs) on the efficacy and safety of Trimetazidine in treating patients with SAP were retrieved in the following databases as CNKI (1997 to June 2011), WanFang Data (1989 to June 2011), MEDLINE (1966 to June 2011), EMbase (1974 to June 2011), CBM (1989 to June 2011) and Cochrane Central Database (1989 to June 2011). The literature which met the inclusion and exclusion criteria were selected, data were extracted, the quality was evaluated, and meta-analysis was performed by using RevMan 5.0 software. Results A total of 15 RCTs involving 1 500 patients were included. The meta-analysis showed that, compared with the control group, TMZ was significantly superior in the following 5 aspects: the time to 1 mm drop of ST segment (WMD=0.84, 95%CI 0.74 to 0.93, P=0.000 01), duration of doing exercise (WMD=0.82, 95%CI 0.73 to 0.91, P=0.000 01), and time to onset of angina (WMD=1.18, 95%CI 0.87 to 1.50, Plt;0.000 01) in the treadmill test, weekly mean number of angina attacks (WMD= –1.79, 95%CI –1.93 to –1.66, Plt;0.000 01), and weekly side effects between TMZ and the control group (RR=0.83, 95%CI 0.52 to 1.32, P=0.42). Conclusion Based on current studies, TMZ is superior to other medicines in the control group for SAP at present, and it has no significant difference in side effects compared with the control group, so it is regarded as an effective and safe drug. For the quality restrictions and possible publication bias of the included studies, this conclusion needs to be confirmed by more high quality, large sample, multi-center, double blind RCTs.
Objective To investigate the value of extravascular lung water index ( EVLWI) and intrathoracic blood volume index ( ITBVI) monitoring in fluid management of severe pneumonia patients with sepsis shock.Methods A prospective controlled study was conducted in106 patients who were diagnosed as severe pneumonia with sepsis shock in intensive care unit fromJanuary 2010 to February 2013. 54 patients who received pulse indicator continuous output ( PiCCO) monitoring were enrolled into the EVLWI + ITBVI group, and EVLWI and ITBVI were used as indicator of fluid management. 52 patients who received central venous pressure ( CVP) as indicator of traditional fluid managementwere enrolled into the control group. The time and the rate to achieve early goal-directed therapy ( EGDT) target were compared between two groups. Acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) , sepsis related organ failure assessment ( SOFA) , noradrenaline dosage, serumlactic acid, serum creatinine were compared between 1 day and 3 days after treatment. The characteristics of fluid management were recorded and compared within 72 hours. Mechanical ventilation ratio, duration of mechanical ventilation, ICU stay and 28-day mortality were compared between two groups. Results The ratio of achieving EGDT target in 6 hours was significantly higher in the EVLWI + ITBVI group than that in the control group ( 75.9% vs. 55.7% , Plt;0.05) , whereas the time and the ratio to achieve EGDT target in 24 hours were not statistically different. APACHE Ⅱ, SOFA, norepinephrine dosage, serum lactate were significantly decreased 3 days after treatment in the EVLWI + ITBVI group, but did not change significantly in the control group. On3 days after treatment, serumcreatinine was increased in the control group, and did not change significantly in the EVLWI + ITBVI group. The fluid intake and fluid balance volume during 0-6 hours period were significantly higher in the EVLWI + ITBVI group than those in the control group ( Plt;0.05) , but showed no difference ( Pgt;0.05) in other periods. Mechanical ventilation ratio, duration of mechanical ventilation, ICU stay and 28-days mortality were significantly lower in the EVLWI + ITBVI group compared with the control group ( Plt;0.05) . Conclusion Compared with CVP, ITBVI and EVLWI can more accurately assess and guide fluid management in severe pneumonia patients with septic shock with less duration of mechanical ventilation, ICU stay and mortality.
