OBJECTIVE: To investigate the hemodynamic effect of Shen-Fu Injection (, SFI) in early volume resuscitation treated septic shock patients by monitoring pulse indicator continuous cardiac output (PICCO). METHODS: All septic shock patients admitted in the Intensive Care Unit of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from January 1st, 2014 to December 31th, 2015, were reviewed, and totally 65 were enrolled in this study. They were assigned to SFI group (33 cases) and control group (32 cases). All 65 patients underwent conventional treatment mainly including volume resuscitation, antibiotics and vasoactive drugs therapy. The patients of the SFI group received additional 100 mL of SFI intravenously every 12 h. In all 65 patients, the PICCO arterial catheter and vein catheter were implanted within 1 h after the diagnosis of septic shock. In the course of early volume resuscitation, hemodynamic data of patients were recorded by PICCO monitor at 0, 12, and 24 h after the catheter implantation. RESULTS: The hemodynamic indices of the two groups showed no significant differences at the beginning of 0 h (P>0.05). At 12 and 24 h, the hemodynamic indices of SFI group were significantly improved in comparison with the control group (P<0.05), including cardiac index (CI), global end diastolic volume index (GEDI), mean arterial pressure (MAP) and heart rate (HR). In addition, there was no significant change of extra-vascular lung water index between the two groups (P>0.05). CONCLUSION SFI significantly improved hemodynamic indices such as CI, GEDI, MAP and HR in early volume resuscitation treated septic shock patients.

OBJECTIVETo compare the effect of Shen-Fu Injection (SFI) and epinephrine on the expression of sarcoplasmic reticulum Ca(2+) ATPase 2a (SERCA2a) in a pig model with post-resuscitation myocardial dysfunction.

METHODSVentricular fibrillation (VF) was electrically induced in Wu-zhi-shan miniature pigs. After 8 min of untreated VF and 2 min of cardiopulmonary resuscitation (CPR), all animals were randomly administered a bolus injection of saline placebo (SA group, n=10), SFI (0.8 mg/kg, SFI group, n=10) or epinephrine (20 μg/kg, EPI group, n=10). After 4 min of CPR, a 100-J shock was delivered. If the defibrillation attempt failed to attain restoration of spontaneous circulation (ROSC), manual chest compressions were rapidly resumed for a further 2 min followed by a second defibrillation attempt. Hemodynamic variables were recorded, and plasma concentrations of catecholamines were measured. Adenylate cyclase (AC), cyclic adenosine monophosphate (cAMP) and the expressions of β1-adrenoceptor (AR) and SERCA 2a were determined.

RESULTSCardiac output, left ventricular dp/dtmax and negative dp/dtmax were significantly higher in the SFI group than in the SA and EPI groups at 4 and 6 h after ROSC. The expression of β1-AR and SERCA2a at 24 h after ROSC were significantly higher in the SFI group than in the SA and EPI groups (P<0.05 or P<0.01).

CONCLUSIONSThe administration of epinephrine during CPR decreased the expression of SERCA2a and aggravated postresuscitation myocardial function (P<0.01). SFI attenuated post-resuscitation myocardial dysfunction, and the mechanism might be related to the up-regulation of SERCA2a expression.

BACKGROUNDPrevious studies have suggested that β1-receptor blockers benefit septic shock patients. This study aimed to determine whether β1-receptor blockers benefit tissue perfusion in sepsis and to identify parameters to reduce the risk of this drug in sepsis.

METHODSConsecutive septic shock patients were recruited from the Intensive Care Unit of Peking Union Medical College Hospital within 48 h of diagnosis. All patients were hemodynamically stable and satisfactorily sedated with a heart rate (HR) ≥100 beats/min. Esmolol therapy achieved the target HR of 10-15% lower than the baseline HR. Clinical and physiological data of patients were collected prospectively within 1 h prior to esmolol therapy and 2 h after achieving the targeted HR.

RESULTSSixty-three patients were recruited. After esmolol therapy, blood pressure was unaltered, whereas stroke volume (SV) was increased compared with before esmolol therapy (43.6 ± 22.7 vs. 49.9 ± 23.7 ml, t = -2.3, P = 0.047). Tissue perfusion, including lactate levels (1.4 ± 0.8 vs. 1.1 ± 0.6 mmol/L, t = 2.6, P = 0.015) and the central venous-to-arterial carbon dioxide difference (5.6 ± 3.3 vs. 4.3 ± 2.2 mmHg, t = 2.6 P = 0.016), was also significantly decreased after esmolol therapy. For patients with increased SV (n = 42), cardiac efficiency improved, and esmolol therapy had a lower risk for a decrease in cardiac output (CO). Therefore, pretreatment cardiac systolic and diastolic parameters with (n = 42)/without (n = 21) an increase in SV were compared. Mitral lateral annular plane systolic excursion (MAPSElat) in patients with increased SV was significantly higher than that in those without increased SV (1.3 ± 0.3 vs. 1.1 ± 0.2 cm, t = 2.4, P = 0.034).

CONCLUSIONSSV of septic shock patients is increased following esmolol therapy. Although CO is also decreased with HR, tissue perfusion is not worse. MAPSElat can be used to predict an increase in SV before esmolol use.

OBJECTIVETo compare the effects of Shenfu Injection (SFI) and epinephrine (EPI) on catecholamine levels in a porcine model of prolonged cardiac arrest (CA).

METHODSAfter 8 min of untreated ventricular fibrillation, 24 Wuzhishan miniature pigs were randomly assigned to one of the three groups (n=8 per group) and received central venous injection, respectively: SFI group (1 mL/kg), EPI group (20 μg/kg EPI), and normal saline (NS) group. Cardiac output (CO), maximum rate of increase/decrease in left ventricular pressure (±dp/dt), serum levels of EPI, norepinephrine (NE), and dopamine (DA) were determined at baseline and at 0.5, 1, 2, and 4 h after restoration of spontaneous circulation.

RESULTSThe duration of cardiopulmonary resuscitation was shorter in the EPI and SFI groups than in the NS group (P<0.05). The EPI level increased significantly after restoration of spontaneous circulation (ROSC) in all three groups, and was significantly different between the EPI group and the other two groups immediately after ROSC (both P<0.01), but these differences gradually disappeared over time. There were no significant differences in NE or DA levels among the three groups, and there were no correlations between catecholamine levels and CO or dp/dt (P>0.05).

CONCLUSIONSSFI did not significantly affect endogenous catecholamine levels during cardiopulmonary resuscitation after prolonged ventricular fibrillation. However, SFI improved oxygen metabolism, and produced a better hemodynamic status compared with EPI. SFI might be a potentially vasopressor drug for the treatment of CA.

PURPOSE: The aim of this study was to evaluate the effects of premedication with oral atenolol or enalapril, in combination with remifentanil under sevoflurane anesthesia, on intraoperative blood loss by achieving adequate deliberate hypotension (DH) during orthognathic surgery. Furthermore, we investigated the impact thereof on the amount of nitroglycerin (NTG) administered as an adjuvant agent. MATERIALS AND METHODS: Seventy-three patients undergoing orthognathic surgery were randomly allocated into one of three groups: an angiotensin converting enzyme inhibitor group (Group A, n=24) with enalapril 10 mg, a beta blocker group (Group B, n=24) with atenolol 25 mg, or a control group (Group C, n=25) with placebo. All patients were premedicated orally 1 h before the induction of anesthesia. NTG was the only adjuvant agent used to achieve DH when mean arterial blood pressure (MAP) was not controlled, despite the administration of the maximum remifentanil dose (0.3 microg kg-1min-1) with sevoflurane. RESULTS: Seventy-two patients completed the study. Blood loss was significantly reduced in Group A, compared to Group C (adjusted p=0.045). Over the target range of MAP percentage during DH was significantly higher in Group C than in Groups A and B (adjusted p-values=0.007 and 0.006, respectively). The total amount of NTG administered was significantly less in Group A than Group C (adjusted p=0.015). CONCLUSION: Premedication with enalapril (10 mg) combined with remifentanil under sevoflurane anesthesia attenuated blood loss and achieved satisfactory DH during orthognathic surgery. Furthermore, the amount of NTG was reduced during the surgery.

OBJECTIVETo evaluate the efficacy and safety of Ginkgo Biloba extract for patients with angina pectoris according to the available evidence.

METHODSElectronic databases were searched for all of the randomized controlled trials (RCTs) of angina pectoris treatments with Ginkgo Biloba extract, either alone or combined with routine Western medicine (RWM), and controlled by untreated, placebo, Chinese patent medicine, or RWM treatment. The RCTs were retrieved from the following electronic databases: PubMed/MEDLINE, ProQuest Health and Medical Complete, Springer, Elsevier, and ProQuest Dissertations and Theses, Wanfang Data, China National Knowledge Infrastructure (CNKI), VIP database, China Biology Medicine (CBM), Chinese Medical Citation Index (CMCI), from the earliest database records to December 2012. No language restriction was applied. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. RevMan 5.1.0 provided by Cochrane Collaboration The data were analysed by using.

RESULTSA total of 23 RCTs (involving 2,529 patients) were included and the methodological quality was evaluated as generally low. Ginkgo Biloba extract with RWM was more effective in angina relief and electrocardiogram improvement than RWM alone. Reported adverse events included epigastric discomfort, nausea, gastrointestinal reaction, and bitter taste.

CONCLUSIONSGinkgo Biloba extract may have beneficial effects on patients with angina pectoris, although the low quality of existing trials makes it difficult to draw a satisfactory conclusion. More rigorous, high quality clinical trials are needed to provide conclusive evidence.

PURPOSE: Atrial natriuretic peptide (ANP) has a variety of pharmacologic effects, including natriuresis, diuresis, vasodilatation, and suppression of the renin-angiotensin system. A recent study showed that ANP infusion improved hypoxemia and pulmonary hypertension in a lung injury model. On the other hand, the pulse contour cardiac output (PiCCO(TM)) system (Pulsion Medical Systems, Munich, Germany) allows monitoring of the intravascular volume status and may be used to guide volume therapy in severe sepsis and critically ill patients. MATERIALS AND METHODS: We treated 10 pulmonary edema patients without heart disease with human ANP (HANP). The patients were divided into two groups: a group with normal Intrathoracic Blood Volume (ITBV) (900-1100 mL/m2) (n = 6), and a group with abnormal ITBV (n = 4), as measured by the PiCCOtrade mark device; the extravascular lung water (EVLW) and pulmonary vascular permeability index (PVPI) in the two groups were compared. RESULTS: The average patient age was 63.9 +/- 14.4 years. The normal ITBV group showed significant improvement of the EVLW (before, 16.7 +/- 2.7 mL/kg; after, 10.5 +/- 3.6 mL/kg; p = 0.0020) and PVPI (before, 3.2 +/- 0.3; after, 2.1 +/- 0.7; p = 0.0214) after the treatment. The abnormal ITBV group showed no significant improvement of either the EVLW (before, 16.3 +/- 8.9 mL/kg; after, 18.8 +/- 9.6 mL/kg; p = 0.8387) or PVPI (before, 2.3 +/- 0.8; after, 2.7 +/- 1.3; p = 0.2782) after the treatment. In both groups, the EVLW and PVPI were strongly correlated with the chest X-ray findings. CONCLUSION: We conclude that HANP supplementation may improve the EVLW and PVPI in pulmonary edema patients without heart disease with a normal ITBV. The PiCCO(TM) system seems to be a useful device for the management of pulmonary edema.

OBJECTIVETo study the protective effects and the possible mechanism of shengmai for injection(SM) against the experimental acute cardiogenic shock.

METHODThe experimental acute cardiogenic shock model was established by ligating the anterior descending cornonary in dogs. The effects of SM on cardiogenic shock were investigated by measuring the hemodynamics parameter, the activity of LDH, CK, SOD and the contents of MDA in blood serum.

RESULTIn the dogs treated with SM, the mean arterial pressure (MAP), heart rate (HR), left ventricular pressure (LVP), the maximum of its first derivative (+/- dp/dtmax), the cardiac output (CO) and the cardiac index (CI) were increased significantly. The left ventricular end diastolic pressure (LVEDP) and the peripheral vascular resistance (TPVR) were decreased significantly, the myocardial infarct size was redused observely. In addition, the activity of LDH, CK and the contents of MDA in serum were decreased significantly, however the activity of SOD was increased observely.

CONCLUSIONThe results indicate that SM has the protective effects on cardiogenic shock.
