Objective To observe hemodynamic characteristics and the correlation with syndrome types of traditional Chinese medicine (TCM) in patients with septic shock, so as to direct the treatment based on syndrome differentiation. Methods A prospective observation was conducted. Sixty-eight patients with septic shock admitted to the Department of Critical Care Medicine of Dade Road General Hospital of Guangdong Hospital of TCM from January 2013 to July 2015 were enrolled. Pulse indicating continuous cardiac output (PiCCO) was used to monitor the hemodynamic changes, including heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), cardiac index (CI), global end diastolic volume index (GEDVI), extravascular lung water index (EVLWI), maximum rate of the increase in pressure (dPmax) and systemic vascular resistance index (SVRI), for assessment of hemodynamics. According to the CI, the patients were divided into two groups , i.e. high CI group (CI ≥ 50.0 mL·s-1·m-2, n = 34) and low CI group (CI < 50.0 mL·s-1·m-2, n = 34), and the clinical and hemodynamic characteristics of two groups were investigated. The TCM differentiation was conducted with four syndromes and four methods, and the hemodynamic characteristics of different syndrome types were investigated, the correlation between the TCM syndrome factors and hemodynamic parameters was analyzed. The patients were divided into survival group and death group, and clinical parameters and hemodynamic characteristics were compared between two groups. Results The acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and blood glucose of low CI group were higher than those of high CI group [APACHEⅡ score: 24.4±7.2 vs. 19.8±7.4, t = -2.279, P = 0.023; blood glucose (mmol/L): 9.7 (7.7, 14.6) vs. 6.7 (5.6, 10.0), Z = -2.257, P = 0.024], CI and GEDVI were lowered [CI (mL·s-1·m-2): 36.7±8.3 vs. 68.4±16.7, t = 10.285, P = 0.000; GEDVI (mL/m2): 689.0 (566.0, 883.8) vs. 838.5 (692.8, 1 247.3), Z = -2.711, P = 0.007], while SVRI was increased [kPa·s·L-1·m-2: 248.7 (202.1, 324.5) vs. 143.4 (102.7, 171.4), Z = -5.336, P = 0.000]. Accompanied symptoms were found to occur more commonly in septic shock patients, and the most common syndrome elements were Qi deficiency syndrome (n = 45), blood stasis syndrome (n = 40), heat-toxin syndrome (n = 37), Fushi syndrome (n = 24) and Yin deficiency syndrome (n = 10), respectively. There was no significant difference in hemodynamic parameters among patients with five types of syndrome (all P > 0.05). However, only the CI of those with Qi deficiency syndrome was significantly lower than that of heat-toxin syndrome (mL·s-1·m-2: 48.3±18.3 vs. 53.3±21.7, P < 0.05). While the results after removing the effect of accompanied symptoms showed that CI of Qi deficiency syndrome was significantly lower than that of non-Qi deficiency syndrome (mL·s-1·m-2: 48.3±18.3 vs. 61.7±21.7, t = -2.783, P = 0.007), CI of heat-toxin syndrome was significantly higher than that of non-heat-toxin syndrome (mL·s-1·m-2: 58.3±21.7 vs. 48.3±16.7, t = 2.133, P = 0.037), EVLWI of blood stasis syndrome was significantly lower than that of non-blood stasis syndrome [mL/kg: 10.0 (7.0, 15.1) vs. 14.9 (8.5, 26.8), Z = -2.075, P = 0.038]. Compared with survival group (n = 38), APACHEⅡ score in death group (n = 30) was increased (25.8±8.4 vs. 19.1±5.4, t = -3.940, P = 0.000), the proportion of continuous renal replacement therapy (CRRT) was increased [60.0% (18/30) vs. 31.6% (12/38), χ2 = 5.493, P = 0.019], HR was increased (bpm: 118.5±20.5 vs. 98.1±19.9, t = -4.157, P = 0.000), and the proportion of Qi deficiency syndrome was increased [86.7% (26/30) vs. 50.0% (19/38), χ2 = 10.070, P = 0.002]. Conclusions Patients with sepsis shock may be divided into high-output and low-resistance & low-output and high-resistance groups according to hemodynamics, with respective hemodynamic characteristics. Hemodynamic performance differed among different syndrome types, and there was a certain relationship. Hemodynamic monitoring with PiCCO was a useful supplement of TCM, which was good for the evidence-based medicine.

ObjectiveTo investigate the effects of Xuebijing injection on hemodynamics, cardiac function, and endothelial function in patients with severe sepsis in order to study the therapeutic effect of Xuebijing in the treatment of severe sepsis.Methods A prospective randomized controlled trial was conducted. Sixty-six severe sepsis patients admitted to the Department of Critical Care Medicine of Guangdong Hospital of Traditional Chinese Medicine from March 2013 to February 2014 were enrolled. The patients were divided into control group (n = 31) and Xuebijing group (n= 35). The patients in both groups were treated according to 2012 international guidelines for management of severe sepsis and septic shock, and the patients in Xuebijing group received Xuebijing injection of 50 mL (added with 100 mL of 0.9% sodium chloride injection) twice a day for 5 days, and those in control group received instead 150 mL of 0.9% sodium chloride injection for 5 days. The heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), and dosage of vasoactive drugs before and 1 day and 5 days after treatment were determined for hemodynamics assessment. Blood lactic acid (Lac), central venous oxygen saturation (ScvO2), and difference in arterial-venous blood carbon dioxide pressure (Pv-aCO2) were determined for microcirculation assessment. The left ventricular ejection fraction (LVEF), cardiac output (CO), left ventricular end diastolic diameter (LVEDD), the ratio of blood flow of mitral orifice between rapid filling period and atrial systole period (E/A), and B-type natriuretic peptide (BNP) were determined for cardiac function assessment. Vascular endothelial growth factor (VEGF) and soluble receptor (sFLT-1) were assessed for endothelial function assessment. The relationship among the indexes of the hemodynamics, microcirculation, cardiac function, and endothelial function was analyzed with Pearson related-analysis.Results After treatment, HR, MAP, CVP, Lac, ScvO2, and Pv-aCO2 were improved in both groups compared with those before treatment, and the dosage of norepinephrine (NE) was decreased in Xuebijing group. Compared with control group, MAP at 5 days after treatment in Xuebijing group was significantly increased [mmHg (1 mmHg =0.133 kPa): 74.9±10.7 vs. 70.2±6.6,P< 0.05], the dosage of NE was decreased [μg·kg-1·min-1: 0.01 (0.00, 0.22) vs. 0.10 (0.05, 0.80),P< 0.05], LVEF was significantly increased (0.617±0.125 vs. 0.533±0.129,P< 0.05), BNP was significantly decreased [ng/L: 117.3 (52.0, 443.0) vs. 277.2 (67.9, 2 370.2),P< 0.05], while VEGF showed no significant change (ng/L: 101.1±23.2 vs. 89.6±20.5,P> 0.05), and sFLT-1 was significantly decreased (ng/L:245.7±86.2 vs. 295.1±95.1,P< 0.05). It was shown by Pearson coefficient bivariate correlation analysis that sFLT-1 was negatively correlated with MAP and ScvO2 (r= -0.569,P= 0.000;r= -0.341,P= 0.008) 5 days after treatment, while it was positively associated with Lac and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score (r= 0.749,P= 0.000;r= 0.645,P= 0.000).Conclusions In patients with severe sepsis, there are hemodynamics disorders and effect in microcirculation perfusion. Xuebijing injection can improve hemodynamics and cardiac function in the patients with severe sepsis, and the mechanism may be related to the improvement of endothelial function.

Objective To observe the effect of Xinmailong injection on microcirculation in patients with septic shock,so as to understand the application effect and value of Xinmailong injection in patients with septic shock.Methods A total of 82 patients with septic shock treated in the intensive care unit of our hospital were selected as the research objects and randomly divided into two groups.41 patients in the control group were treated with conventional septic shock cluster therapy,and 41 patients in the treatment group were treated with Xinmailong injection on the basis of cluster therapy in the control group.Then hemodynamic parameters(HR,CVP,CO,MAP,SVR),hemorheology(whole blood reducing viscosity,hematocrit,fibrinogen,platelet aggregation rate),microcirculation perfusion indexes(oxygenation index,blood lactate level,SCVO2,Pcv-aCO2)and 28-day survival rate were detected and compared between the two groups before and after treatment.Results Before treatment,there were no significant differences in hemodynamic parameters,blood rheology and microcirculation perfusion indexes between the two groups(P>0.05).After treatment,the above test results of the two groups were signifi-cantly improved,and the test results of the treatment group were significantly better than those of the control group,and the 28-day survival rate was also better than that of the control group.The differences were statistically significant(P<0.05).Conclusion Xinmailong injection can significantly improve the hemodynamic parameters,blood rheology and microcirculation perfusion indexes,and improve the 28-day survival rate of patients with sepsis.It has a positive clinical effect in the treatment of septic shock patients.
