Astragaloside IV Attenuates Polymicrobial Sepsis-Induced Cardiac Dysfunction in Rats via IKK/NF-κB Pathway.

OBJECTIVE: To evaluate the protective effects of Astragaloside IV (AST) in a rat model of myocardial injury induced by cecal ligation and puncture (CLP). METHODS: The model of sepsis-induced cardiac dysfunction was induced by CLP. Using a random number table, 50 specific pathogen free grade of Sprague Dawley rats were randomized into 5 groups: the sham group (sham), the model group (CLP, 18 h/72 h) and AST group (18 h/72 h). Except the sham group, the rats in other groups received CLP surgery to induce sepsis. CLP groups received intragastric administration with normal saline after CLP. AST groups received intragastric administration with AST solution (40 mg/kg) once a day. The levels of inflammatory mediators and oxidative stress markers in the serum of the septic rats were determined via enzyme-linked immunosorbent assay (ELISA) at different time point, such as interleukin 6 (IL-6), IL-10, high mobility group box-1 protein B1 (HMGB-1), superoxide dismutase (SOD), and malondialdehyde (MDA). Cardiac function was determined by echocardiography. Moreover, changes in myocardial pathology were evaluated using hematoxylin and eosin staining. The levels of lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were analysed to determine the status of CLP-induced myocardium. In addition, the apotosis of myocardial cells was analysed by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL). The protein levels of B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X (Bax), IκB kinase α (IKKα), nuclear factor kappa B p65 (NF-κB p65) were detected by Western blot analysis. Moreover, survival rate was investigated. RESULTS: AST improved the survival rate of CLP-induced rats by up to 33.3% (P<0.05). The cardioprotective effect of AST was observed by increased ejection fraction, fractional shortening and left ventricular internal diameter in diastole respectively (P<0.01 or P<0.05). Subsequently, AST attenuated CLP-induced myocardial apoptosis and the ratio of Bcl-2/Bax in the myocardium, as well as the histological alterations of myocardium (P<0.01 or P<0.05); the generation of inflammatory cytokines (IL-6, IL-10, HMGB-1) and oxidative stress markers (SOD, MDA) in the serum was significantly alleviated (P<0.01 or P<0.05). On the other hand, AST markedly suppressed CLP-induced accumulation of IKK-α and NF-κB p65 subunit phosphorylation (P<0.01 or P<0.05). CONCLUSIONS: AST plays a significant protective role in sepsis-induced cardiac dysfunction and survival outcome. The possible mechanism of cardioprotection is dependent on the activation of the IKK/NF-κB pathway in cardiomyocytes.

Sodium Tanshinone IIA sulfonate for acute myocardial infarction: a systematic review and Meta-analysis.

OBJECTIVE: To investigate the efficacy and safety of Sodium tanshinone ⅡA sulfonate (STS) plus the conventional treatment on acute myocardial infarction (AMI) patients. METHODS: We searched several electrical databases and hand searched several Chinese medical journals up to January 2019. Randomized controlled trials (RCTs) comparing STS plus conventional treatment with conventional treatment were retrieved. Study screening, data extraction, quality assessment, and data analysis were conducted in accordance with the Cochrane standards. RESULTS: Sixteen trials involving 1383 people were included. The Meta-analysis showed STS combined with conventional treatment was a better treatment option than conventional treatment alone in reducing the risk of mortality, heart failure, arrhythmia and shock. In addition, STS was associated with improvement in left ventricular ejection fraction (LVEF) and left ventricular end diastolic dimension (LVEDD). No significant difference of STS was found on recurrent angina and recurrent AMI. However, the safety of STS remained uncertain for limite data. CONCLUSION: Compared with conventional treatment alone, STS combined with conventional treatment may provide more benefits for patients with AMI. Due to the fact that the overall quality of all included trials is generally low, further large-scale high quality trials are warranted.

Effect of Tongguan Capsules () on Restenosis after Coronary Stent Implantation: Study Protocol for A Randomized Controlled Trial.

BACKGROUND: Although percutaneous coronary intervention (PCI) had become widely employed therapeutic procedure for coronary artery disease, stent restenosis limited the benefits of this revascularization and the question how to prevent such events remained unresolved. While numerous empirical observations suggested Tongguan Capsules (), a patented Chinese Medicine, could decrease frequency and duration of angina pectoris attacks, evidence supporting its efficacy on restenosis remained inadequate. OBJECTIVE: This trial was designed to determine whether Tongguan Capsules would reduce restenosis rate in patients after successful stent implantation. METHODS: Approximately 400 patients undergoing percutaneous coronary stent deployment were enrolled and randomized to control group or Tongguan Capsules (4.5 g/d) for 3 months. All patients received standard anti-platelet, anti-coagulation and lipid-decreasing treatments, concurrently. The primary clinical endpoint was the 12-month incidence of the major adverse cardiovascular events (defined as cardiac death, myocardial infarction, and recurrence of symptoms requiring additional revascularization). The angiographic end point was restenosis rate at 6 months. CONCLUSION: This study would provide important evidence for the use of Tongguan Capsules in patients after stent implantation in combination with routine therapies, which may significantly reduce incidence of the restenosis so as to potentially improve the clinical outcomes.

Beneficial Effects of Baduanjin Exercise on Left Ventricular Remodelling in Patients after Acute Myocardial Infarction: an Exploratory Clinical Trial and Proteomic Analysis.

BACKGROUND: The beneficial effects of physical exercise on cardiac remodelling improvement after myocardial infarction have already been suggested. However, the results of previous clinical trials have not been consistent. Moreover, the putative molecular mechanisms leading to the clinically observed effects of physical exercise still remain elusive. AIM: We aimed to evaluate whether the well-defined and strictly controlled traditional Chinese Qigong Baduanjin exercise (BE) would attenuate the adverse left ventricular (LV) remodelling in patients with ST-elevation myocardial infarction (STEMI). METHODS: A total of 110 clinically stable STEMI patients, following successful revascularization of their infarcted coronary arteries, were randomized and enrolled in two groups: 56 were subjected to a 12-week BE-based cardiac rehabilitation programme (BE group), and the remaining 54 were exposed to the usual physical exercise (control group) for the same time period. The primary outcome was the change from baseline to 6 months in the echocardiographic LV end-diastolic volume index (ΔLVEDVi). Proteomic analysis was also performed to uncover associated mechanisms. RESULTS: Compared with the control group, the BE group showed significantly lower ΔLVEDVi (-5.1 ± 1.1 vs. 0.3 ± 1.2 mL/m2, P < 0.01). Proteomic analysis revealed BE-induced variations in the expression of 80 proteins linked to regulation the of metabolic process, immune process, and extracellular matrix reorganization. Furthermore, correlation analyses between the validated serum proteomes and primary endpoint demonstrated a positive association between ΔLVEDVi and MMP-9 expression, but a negative correlation between ΔLVEDVi and CXCL1 expression. CONCLUSION: This is the first study indicating that BE in STEMI patients can alleviate adverse LV remodelling associated with beneficial energy metabolism adaptation, inflammation curbing, and extracellular matrix organization adjustment.

The Effect of Xinmailong Infusion on Sepsis-Induced Myocardial Dysfunction: a Pragmatic Randomized Controlled Trial.

ABSTRACT: Sepsis-induced myocardial dysfunction (SIMD) contributes significantly to cardiovascular dysfunction during septic shock. We aimed to evaluate the potential role of Xinmailong injection (XMLI), a polypeptide medicine extracted from Periplaneta americana, in reversing the progression of myocardial damage to SIMD in sepsis patients. This was a multicenter, randomized, double-blind, parallel-group trial. We recruited all patients consecutively admitted to intensive care units (ICUs) who were aged 18 to 85 years old and met the sepsis 3.0 criteria. The primary outcome measure was the incidence of sepsis-induced myocardial dysfunction while in the ICU. Of the 192 patients, 96 were assigned to the treatment group, and 96 to the control group. Subsequently, 41 patients [41/96 (42.7%)] in the XMLI group and 61 patients in the placebo group [61/96 (63.5%)] were confirmed to have diastolic dysfunction on the fifth day (D5). The incidence of diastolic SIMD was significantly different between the two groups (P = 0.004). There were 36 deaths in the two groups during the 28-day follow-up, with a general mortality rate of 18.8% (36/192). The 28-day mortality rates were not significantly different between the groups (P = 0.45). However, the brain natriuretic peptide (BNP) plasma concentration trends on D0, D2, and D5 significantly differed between the two groups (P = 0.049). In septic patients, XMLI decreased the occurrence rate of diastolic SIMD more effectively than the placebo. The improvement in serum BNP concentration was also greater in the XMLI group. XMLI may, therefore, effectively and safely improve cardiac function in patients with sepsis.

Effect of Baduanjin Sequential Therapy on the Quality of Life and Cardiac Function in Patients with AMI After PCI: A Randomized Controlled Trial.

PURPOSE: The purpose of this study was to examine the effects of Baduanjin sequential therapy (BST) on the quality of life and cardiac function in patients with AMI after PCI. SUBJECTS: 96 patients with AMI after PCI were randomly assigned as subjects to two groups: BST group who received 24 weeks of BST training and control group who received no training. METHODS: The methods used in this study included the changes in SF-36 subscales, the measures of left ventricular ejection fraction (LVEF), N-terminal pro-B-type natriuretic peptide (NT-pro-BNP), the body mass index (BMI), and the abdominal circumference. RESULTS: Of the 96 participants, 82 total patients completed the entire study. At 12 weeks, role physical and health transition of SF-36 were significantly different between the two groups, with a difference of 26.12 (95% CI, 11.59 to 40.64) in role physical and a difference of 15.94 (95% CI, 5.60 to 26.28) in health transition (p < 0.05). However, there were statistically significant differences in all aspects of SF-36 between the two groups at 24 weeks (p < 0.05). The BST also lowered abdominal circumference and BMI as compared with the control group. In the 24-week follow-up, a significant difference was found in the decline of the LVEF in the control group (p=0.020), while there was a nonsignificant difference in the BST group (p=0.552). Compared with the control group, the BST group reduced 50 pg/ml on the NT-pro-BNP at 24 weeks (p=0.013). The effects of BST exercise were maintained at 24 weeks after the intervention. No serious adverse events were observed. CONCLUSIONS: The BST appears to improve the quality of life in patients with AMI after PCI, with additional benefits of lowered abdominal circumference and BMI and improved level of cardiac function. This trial is registered with NCT02693795.

Tongguan capsule derived-herb ameliorates remodeling at infarcted border zone and reduces ventricular arrhythmias in rats after myocardial infarction.

OBJECTIVE: Tongguan Capsule, a traditional Chinese medicine, is safe to use and is efficient in treating ischemic heart diseases. The present study aimed to investigate whether Tongguan capsule derived-herb (TGD) can mitigate left ventricular remodeling and dysfunction in post myocardial infarction (MI) rats as well as reduce arrhythmias. DESIGN AND METHODS: MI was induced by a ligation of the left anterior descending coronary artery. TGD was administered to the post-MI rats over a period of 4 weeks. TGD treatment significantly attenuated tachyarrhythmia inducibility and cardiac dysfunction in post-MI heart. Echocardiogram showed that TGD significantly reduced the development of ventricular remodeling. Histological study revealed that TGD significantly reduced myocardial interstitial collagen deposition, myocyte area and α-smooth muscle actin (α-SMA) expression, and increased connexin 43 expression in the infarcted border zone (IBZ). Western blotting results revealed that TGD treatment significantly down-regulated the protein expression levels of type I and III collagen, α-SMA, and up-regulated connexin 43. RT-qPCR results showed that TGD decreased the levels of ANP and BNP. CONCLUSIONS: These findings provided strong evidences that TGD intervention ameliorated interstitial fibrosis, myocyte hypertrophy and gap junction expression in the IBZ, attenuated left ventricular remodeling and dysfunction, and reduced vulnerability to tachyarrhythmia. TGD inhibited IBZ remodeling by its inhibition effect on myofibroblasts differentiation.

Danqi soft capsule prevents infarct border zone remodelling and reduces susceptibility to ventricular arrhythmias in post-myocardial infarction rats.

Danqi soft capsule (DQ) is a traditional Chinese medicine containing Salvia miltiorrhiza and Panax notoginseng; it is safe and efficient in treating ischaemic heart diseases. The purpose of the present study was to assess whether DQ could prevent infarct border zone (IBZ) remodelling and decrease ventricular arrhythmias occurrence in post-myocardial infarction (MI) stage. MI was induced by a ligation of the left anterior descending coronary artery. DQ was administered to the post-MI rats started from 1 week after MI surgery for 4 weeks. The results showed that DQ treatment significantly attenuated tachyarrhythmia induction rates and arrhythmia score in post-MI rats. In echocardiography, DQ improved left ventricular (LV) systolic and diastolic function. Histological assessment revealed that DQ significantly reduced fibrotic areas and myocyte areas, and increased connexin (Cx) 43 positive areas in IBZ. Western blot revealed that DQ treatment significantly reduced the protein expression levels of type I and III collagens, α-smooth muscle actin (α-SMA), transforming growth factor-ß1 (TGF-ß1) and Smad3 phosphorylation, while increasing Cx43 amounts. Overall, these findings mainly indicated that DQ intervention regulates interstitial fibrosis, Cx43 expression and myocyte hypertrophy by TGF-ß1/Smad3 pathway in IBZ, inhibits LV remodelling and reduces vulnerability to tachyarrhythmias after MI. This study presents a proof of concept for novel antiarrhythmic strategies in preventing IBZ remodelling, modifying the healed arrhythmogenic substrate and thus reducing susceptibility to ventricular arrhythmias in the late post-MI period.

Tongguan capsule-derived herb reduces susceptibility to atrial fibrillation by inhibiting left atrial fibrosis via modulating cardiac fibroblasts.

Tongguan capsule is a compound Chinese medicine used to treat ischaemic heart diseases. This study aimed to investigate whether Tongguan capsule-derived herb (TGD) has a preventive effect on atrial fibrillation (AF) in post-myocardial infarction (MI) rats and to determine the underlying mechanisms. MI was induced by ligation of the left anterior descending coronary artery. TGD was administered to the post-MI rats over a 4-week period. The TGD-treated rats had lower rates of AF inducibility and shorter AF durations than the MI rats. TGD improved the left atrial (LA) conduction velocity and homogeneity. It reduced the fibrosis-positive areas and the protein levels of collagen types I and III in the left atrium. In vitro, it inhibited the expression of collagen types I and III by inhibiting the proliferation, migration, differentiation and cytokine secretion of cardiac fibroblasts (CFs). In conclusion, the current study demonstrated that TGD reduces susceptibility to AF and improves LA conduction function in rats with post-MI by inhibiting left atrial fibrosis and modulating CFs. Targeting the CF population may be a novel antiarrhythmic therapeutic approach.

Protective Effects of Danlou Tablet () against Murine Myocardial Ischemia and Reperfusion Injury In Vivo.

OBJECTIVE: To observe the in vivo effect of Danlou Tablet (, DLT) on myocardial ischemia and reperfusion (I/R) injury. METHODS: DLT effects were evaluated in mouse heart preparation using 30-min coronary occlusion followed by 24-h reperfusion and compared among sham group (n=6), I/R group (n=8), IPC group (ischemia preconditioning, n=6) and DLT group (I/R with DLT pretreatment for 3 days, 750 mg•kg-1•day-1, n=8). The effects of DLT were characterized in infarction size (IS) compared with risk region (RR) and left ventricle using the Evans blue/triphenyltetrazolium chloride double dye staining method in vivo. Furthermore, the dose-dependent effect of DLT on I/R injury was evaluated by double staining method. Five different concentrations of DLT (0.625, 1.25, 2.5, 5 and 10 g•kg-1•day-1) were chosen in this study, and dose-response curve of DLT was obtained on these data. RESULTS: The ratio of IS to left ventricle was significantly smaller in the DLT and IPC groups than the I/R group (P<0.05 or P<0.01), the ratio of IS to RR was also reduced in the DLT and IPC groups (P<0.01), while there were no differences in RR among the four groups (P>0.05). Experiments showed incidence of arrhythmias was reduced in the DLT group (P<0.01). Furthermore, DLT produced a dose-dependent inhibitory effect with a half maximal inhibitory concentration of 1.225 g•kg-1•day-1. CONCLUSIONS: Our research concluded that DLT was effective in reducing I/R injury in mice, and provided experimental supports for the clinical use of DLT.

Salvianolate reduces murine myocardial ischemia and reperfusion injury via ERK1/2 signaling pathways in vivo.

OBJECTIVE: To analyze the effects of salvianolate on myocardial infarction in a murine in vivo model of ischemia and reperfusion (I/R) injury. METHODS: Myocardial I/R injury model was constructed in mice by 30 min of coronary occlusion followed by 24 h of reperfusion and pretreated with salvianolate 30 min before I/R (SAL group). The SAL group was compared with SHAM (no I/R and no salvianolate), I/R (no salvianolate), and ischemia preconditioning (IPC) groups. Furthermore, an ERK1/2 inhibitor PD98059 (1 mg/kg), and a phosphatidylinositol-3-kinase (PI3-K) inhibitor, LY294002 (7.5 mg/kg), were administered intraperitoneal injection (i.p) for 30 min prior to salvianolate, followed by I/R surgery in LY and PD groups. By using a double staining method, the ratio of the infarct size (IS) to left ventricle (LV) and of risk region (RR) to LV were compared among the groups. Correlations between IS and RR were analyzed. Western-blot was used to detect the extracellular signal-regulated kinase 1/2 (ERK1/2) and protein kinase B (AKT) phosphorylation changes. RESULTS: There were no significant differences between RR to LV ratio among the SHAM, I/R, IPC and SAL groups (P>0.05). The SAL and IPC groups had IS of 26.1%±1.4% and 22.3%±2.9% of RR, respectively, both of which were significantly smaller than the I/R group (38.5%±2.9% of RR, P<0.05, P<0.01, respectively). Moreover, the phosphorylation of ERK1/2 was increased in SAL group (P<0.05), while AKT had no significant change. LY294002 further reduced IS, whereas the protective role of salvianolate could be attenuated by PD98059, which increased the IS. Additionally, the IS was not linearly related to the RR (r=0.23, 0.45, 0.62, 0.17, and 0.52 in the SHAM, I/R, SAL, LY and PD groups, respectively). CONCLUSION: Salvianolate could reduce myocardial I/R injury in mice in vivo, which involves an ERK1/2 pathway, but not a PI3-K signaling pathway.

Efficacy of Danlou Tablet in Patients with Non-ST Elevation Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention: Results from a Multicentre, Placebo-Controlled, Randomized Trial.

This study seeks to investigate potential cardioprotection of Danlou Tablets in patients undergoing PCI with non-ST elevation acute coronary syndrome (NSTE-ACS). 219 patients with NSTE-ACS were randomised to Danlou Tablet pretreatment (n = 109) or placebo (n = 110). No patients received statins prior to PCI and all patients were given atorvastatin (10 mg/day) after procedure. The main endpoint was the composite incidence of major adverse cardiac events (MACEs) within 30 days after PCI. The proportion of patients with elevated levels of cTn I>5 × 99% of upper reference limit was significantly lower in the Danlou Tablet group at 8 h (22.0% versus 34.5%, p = 0.04) and 24 h (23.9% versus 38.2%, p = 0.02) after PCI. The 30-day MACEs occurred in 22.0% of the Danlou Tablet group and 33.6% in the placebo group (p = 0.06). The incidence of MACE at 90-day follow-up was significantly decreased in the Danlou Tablet group compared to the placebo group (23.9% versus 37.3%, p = 0.03). The difference between the groups at 90 days was the incidence of nonfatal myocardial infarction (22% versus 34.5%, p = 0.04). These findings might support that treatment with Danlou Tablet could reduce the incidence of periprocedural myocardial infarction in patients with ACS undergoing PCI.

Traditional Chinese medicine, Danlou tablets alleviate adverse left ventricular remodeling after myocardial infarction: results of a double-blind, randomized, placebo-controlled, pilot study.

BACKGROUND: Danlou tablets, a patented Chinese Medicine, have been long approved for the treatment of ischemic heart disease in China. While numerous empirical observations suggested Danlou tablets could decrease frequency and duration of angina pectoris attacks, evidence supporting its efficacy on cardiac remodeling remains inadequate. Therefore, this pilot trial was designed to determine whether Danlou tablets would reduce adverse left ventricular (LV) remodeling in patients with myocardial infarction (MI). METHODS AND RESULTS: Eligible patients with acute MI were enrolled and randomly assigned to Danlou tablets or placebo groups, superimposed on standard treatment for MI. Then, in addition to assessment of the clinical outcome, the changes in LV volumes were evaluated by a serial echocardiography. In total, 83 patients (Danlou tablets 42 and placebo 41) completed 90 days of treatment and had complete baseline and outcome data. Standard echocardiographic evaluations revealed significant differences in the change of LV end-diastolic volume index (LVEDVi) between group of patients treated with Danlou tablets and the placebo group (-4.49 ± 7.29 vs. -0.34 ± 9.01 mL/m2, P < 0.001). The reduction in LVEDVi was independent of beta-blocker, ACE inhibitors/ARBs use. Furthermore, treatment with Danlou tablets significantly reduced LV end-systolic volume index (-4.09 ± 5.85 vs. -0.54 ± 5.72 mL/m2, P < 0.001) and improved the LV ejection fraction (4.83 ± 9.23 vs. 0.23 ± 8.15 %, P < 0.001), as compared to placebo. Meaningfully, the incidence of the major adverse cardiovascular events was also lower in patients receiving Danlou tablets (P < 0.05). CONCLUSION: Superimposed on the standard pharmacologic treatment, Danlou tablets significantly reversed post-MI adverse LV remodeling, thereby contributed to the overall positive clinical outcome.

Meanwhile, they concurrently used herbs combination of nourishing Xin and tranquilization, and regulating yin and yang.

Baduanjin Exercise Prevents post-Myocardial Infarction Left Ventricular Remodeling (BE-PREMIER trial): Design and Rationale of a Pragmatic Randomized Controlled Trial.

BACKGROUND: Left ventricular (LV) remodeling following myocardial infarction (MI) is an established prognostic factor for adverse cardiovascular events and the leading cause of heart failure. Empirical observations have suggested that Baduanjin exercise, an important component of traditional Chinese Qigong, may exert potential benefits on cardiopulmonary function. However, the impact of a Baduanjin exercise-based cardiac rehabilitation program for patients recovering from a recent MI has yet to be assessed. The aim of this trial is to evaluate the potential role of Baduanjin exercise in preventing the maladaptive progression to adverse LV remodeling in patients post-MI. METHODS: A total of 110 clinically stable patients following an MI after undergoing successful infarct-related artery reperfusion will be randomly assigned to the Baduanjin exercise group or usual exercise control group. In addition to usual physical activity, participants in the Baduanjin exercise group will participate in a 45 min Baduanjin exercise training session twice a week, for a total of 12 weeks. The primary endpoint will be the percentage change in LV end-diastolic volume index (LVEDVi) assessed using echocardiography from baseline to 6 months. CONCLUSION: The results of this study may provide novel evidence on the efficacy of Baduanjin exercise therapy in post-MI patients in reversing adverse LV remodeling and improving clinical outcome. TRIAL REGISTRATION: Clinical Trials.gov: NCT02693795.

[The hemodynamic characteristics of septic shock and relationship with syndrome types of traditional Chinese medicine].

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/m(2)): 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), χ (2) = 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), χ (2) = 10.070, P = 0.002]. CONCLUSIONS: Patients with sepsis shock may be divided into high-output and low-resistance and 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.

[Effect of Modified Huanglian Jiedu Decoction Purgation Combined Electroacupuncture in Intervening Gastrointestinal Dysfunction of Critically Ill Patients Undergoing Abdominal Surgery].

OBJECTIVE: To observe the effect of purgation and detoxification therapy on gastrointestinal dysfunction of critically ill patients undergoing abdominal surgery. METHODS: Totally 56 inpatients with severe gastrointestinal dysfunction after abdominal surgery at ICU of Guangdong Provincial Hospital of Traditional Chinese Medicine were assigned to the treatment group and the control group, 28 in each group. All patients received routine Western medical treatment. Patients in the treatment group additionally took Modified Huanglian Jiedu Decoction (MHJD) and received electroacupuncture (EA) for 7 days. The first exhaust time, defecation time, scores for gastrointestinal dysfunction, mechanical ventilation time, ICU hospitalization time, and 28-day fatality rate were observed. Furthermore, serum levels of diamine oxidase (DAO) and D-lactic acid were detected at day 1, 3, and 7 after treatment. RESULTS: The first exhaust time and the first defecation time in the treatment group were ahead of schedule, when compared with those of the control group (P <0. 05). Scores for gastrointestinal dysfunction, mechanical ventilation time, serum levels of DAO obviously decreased in the treatment group (P <0. 05). There was no statistical difference in serum levels of D-lactic acid, ICU stay time, the incidence of pulmonary infection, and 28-day mortality between the two groups (P >0. 05). Results of Logistic analysis showed that scores for gastrointestinal dysfunction were related with the incidence of pulmonary infection (P <0. 05). CONCLUSION: MHJD combined EA could promote the recovery of gastrointestinal function in critically ill patients after abdominal surgery via improving intestinal barrier function, which was benefit for shortening mechanical ventilation time.

Danhong Injection (a Traditional Chinese Patent Medicine) for Acute Myocardial Infarction: A Systematic Review and Meta-Analysis.

Objective. We aimed to systematically assess the efficacy and safety of Danhong injection (DHI) for acute myocardial infarction (AMI) patients. Methods. We searched several electrical databases and hand searched several Chinese medical journals. Randomized controlled trials (RCTs) comparing DHI plus conventional western medicine with conventional western medicine plus placebo and RCTs comparing DHI plus conventional western medicine with conventional western medicine were retrieved. Study screening, data extraction, quality assessment, and data analysis were conducted in accordance with the Cochrane standards. Results. 13 RCTs enrolling 979 patients were included. Danhong injection could significantly reduce the risk of mortality, recurrent angina, arrhythmia, and heart failure. In addition, DHI was associated with improvement of left ventricular ejection fraction (LVEF) and reperfusion. No significant difference of DHI was found on recurrent acute myocardial infarction. However, the safety of DHI remained unknown for limited data. Conclusion. DHI might be a potentially efficacious treatment for AMI patients. Nevertheless, the safety of DHI remained uncertain for limited information. Due to the fact that the overall quality of all included studies is generally low, more high quality RCTs are expected to validate the efficacy and safety of DHI for AMI patients.
