Inflammatory bowel disease (IBD) is a chronic and recurrent intestinal disease, and has become a major global health issue. Individuals with IBD face an elevated risk of developing colorectal cancer (CRC), and recent studies have indicated that mitochondrial dysfunction plays a pivotal role in the pathogenesis of both IBD and CRC. This review covers the pathogenesis of IBD and CRC, focusing on mitochondrial dysfunction, and explores pharmacological targets and strategies for addressing both conditions by modulating mitochondrial function. Additionally, recent advancements in the pharmacological modulation of mitochondrial dysfunction for treating IBD and CRC, encompassing mitochondrial damage, release of mitochondrial DNA (mtDNA), and impairment of mitophagy, are thoroughly summarized. The review also provides a systematic overview of natural compounds (such as flavonoids, alkaloids, and diterpenoids), Chinese medicines, and intestinal microbiota, which can alleviate IBD and attenuate the progression of CRC by modulating mitochondrial function. In the future, it will be imperative to develop more practical methodologies for real-time monitoring and accurate detection of mitochondrial function, which will greatly aid scientists in identifying more effective agents for treating IBD and CRC through modulation of mitochondrial 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.

Objective:To investigate the effect of thrombus burden on the clinical outcome of endovascular recanalization in large vessel occlusive stroke.Methods:Patients with acute anterior circulation occlusion who underwent endovascular treatment within 24 hours after onset in Zhengzhou University People′s Hospital from January 2018 to December 2019 were retrospectively collected. According to the clot burden score (CBS) of DSA, total objectives were divided into CBS≥6 group (24 cases) and CBS<6 group (38 cases). Clinical data of the two groups were collected and the modified Rankin scale (mRS) was used to evaluate the clinical outcome at 90 days after surgery. Independent sample t-test, Wilcoxon rank sum test and χ 2 test were used to compare the clinical data between the two groups. Independent risk factors affecting the clinical outcome were analyzed by binary logistic regression. Results:There were no statistically significant differences in basic demographic data, stroke risk factors and other factors between the CBS≥6 group and CBS<6 group ( P>0.05).The proportion of using tirofiban after surgery in the CBS≥6 group (63.2%, 24/38) was lower than that in the CBS<6 group (87.5%, 21/24) (χ2=4.380, P=0.044). The discharge NIHSS score of the CBS≥6 group was [5.0 (3.3, 7.8) points] lower than CBS<6 group [8.5 (1.8, 14.5) points] ( Z=5.221, P=0.022). The proportion of postoperative mRS 0-2 was (91.7%, 22/24) in the CBS≥6 group higher than CBS<6 group(39.5%, 15/38) (χ2=20.486, P=0.001), there were no statistically significant differences between the two groups ( P<0.05). The results of binary logistics regression analysis showed the CBS groups (OR=0.042, 95%CI 0.007-0.244 , P=0.001) was an independent risk factor affecting good outcome. Subgroup analysis of whether tirofiban was used or not showed there was no statistically significant difference in clinical prognosis between the two groups ( P>0.05). Conclusions:The clinical outcome of CBS≥6 group is significantly better than that of CBS<6 group, and patients with small thrombus burden are more likely to get a good clinical outcome of 90 days.

Objective:To investigate the safety and efficacy of endovascular treatment in acute anterior circulation massive cerebral infarction and its prognostic factors.Methods:A retrospective analysis was performed on clinical data of 34 patients with acute anterior circulatory massive cerebral infarction who received intravascular treatment in our hospital from February 2018 to December 2019. The perioperative hemorrhage rate and mortality rate were analyzed in these patients. Modified Rankin scale (mRS) scores were taken as the evaluation standard in the prognoses of these patients during the 90 d of follow up, and the influencing factors affecting the prognoses of patients with massive cerebral infarction were analyzed.Results:The operation was successful in 30 patients (88.2%); the operation time was (97.41±54.58) min, and the number of thrombolysis was (1.91±0.75) times. Distal embolization occurred in 4 patients (11.8%); there were 3 patients with non-symptomatic hemorrhage (8.8%) and 3 patients with symptomatic hemorrhage (8.8%). Cerebral hernia occurred in 7 patients (20.6%); there were 5 deaths (14.4%). During the 90 d of follow up, 13 patients (38.2%) had good prognosis, and 21 (61.8%) had poor prognosis; there were statistically significant differences in NIHSS scores at admission, infarction locations in diffusion weighted imaging, vascular occlusion locations in DSA, pecentages of patients accepted preoperative intravenous thrombolysis and patients with cerebral hernia between the two groups ( P<0.05). NIHSS scores at admission ( OR=0.817, 95% CI: 0.682-0.980, P=0.029), thrombus load scale scores ( OR=5.981, 95%CI: 1.827-19.575, P=0.003), vascular occlusion locations in DSA ( OR=0.031, 95% CI: 0.003-0.311, P=0.003) and pecentage of patients accepted preoperative intravenous thrombolysis ( OR=0.092, 95% CI: 0.010-0.838, P=0.034) were independent factors influencing the prognoses of emergency intravascular treatment. Conclusions:Endovascular recanalization can achieve a relatively good prognosis in patients with massive cerebral infarction. Patients with low NIHSS scores, high thrombotic load scale scores, and middle cerebral artery occlusion, and patients accepted direct intravascular treatment have relatively good prognosis.

Objective:To explore the characteristics of high-density sign of flat-panel CT (FDCT) after endovascular treatment in patients with acute ischemic stroke (AIS) in the anterior circulation of large vessels and their relation with hemorrhagic transformation.Methods:Seventy-eight patients with AIS in the anterior circulation of large vessels accepted endovascular treatment in our hospital from March 2018 to June 2019 were chosen in our study. All patients underwent FDCT, and they were grouped according to the presence of local high-density sign and occurrence of hemorrhagic transformation. The baseline and clinical data of patients from high-density sign group and non-high-density sign group, and from hemorrhagic transformation group and non-hemorrhagic transformation group were compared and analyzed. The correlation between high-density sign and hemorrhagic transformation was analyzed. The morphological characteristics and distribution of FDCT high-density sign in patients from high-density sign group were analyzed, and univariate and multivariate Logistic regression analyses were used to screen the influencing factors for post-operative hemorrhagic transformation in patients from the high-density sign group.Results:(1) The incidence of high-density sign in these patients after endovascular treatment was 41.0% (32/78); as compared with patients in the non-high-density sign group, patients in the high-density sign group had significantly higher rate of hemorrhagic transformation (6.5% vs. 53.1%, P<0.05) and significantly higher 3-month modified Rankin scale (mRS) scores (2.0 [1.0, 3.0] vs. 3.9 [3.0, 5.3], P<0.05). (2) The incidence of hemorrhagic transformation after endovascular treatment was 25.6% (20/78); as compared with those in the non-hemorrhagic transformation group, patients in the hemorrhage transformation group had statistically higher incidence of high-density sign in FDCT (31% vs. 70%, P<0.05); multivariate Logistic regression analysis showed that FDCT high density sign was an independent risk factor for hemorrhage transformation after endovascular treatment ( OR=1.823, 95%CI: 1.125-2.358, P=0.000). (3) In the 32 patients with FDCT high-density sign, 4 (12.5%), 13 (40.6%) and 7 (21.9%) had high-density sign in the cortex and subcortex, basal ganglia, and subarachnoid space, whose hemorrhagic transformation incidences were 75% (3/4), 53.8% (7/13), and 57.1% (4/7), respectively, and mean 3-month mRS scores were 4.5, 3.0 and 4.0, respectively; another 8 patients (25%) had endovascular FDCT high-density sign, whose hemorrhagic transformation incidence was 87.5% (7/8), and 3-month mRS scores were ≥4. (4) Multivariate Logistic regression analysis showed that the vascular opening time ≤6 h was a protective factor for hemorrhage transformation in patients with FDCT high-density sign ( OR=0.687, 95%CI: 0.193-0.936, P=0.044). Conclusions:In patients with AIS in the anterior circulation of large vessels accepted endovascular treatment, FDCT high-density sign indicates high risk of hemorrhage transformation and poor prognosis, especially in patients having high-density sign in the cerebral cortex, subcortical area and intravascular area. Minimizing the vascular opening time may reduce the risk of hemorrhagic transformation in patients with FDCT high-density sign.

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 examine the clinical utility of four methods in diagnosis of tuberculous meningitis.Methods A total of 60 patients with tuberculous meningitis were included as study group and another 70 patients with non-tuberculous intracranial infection as control group. Four methods, including conventional acid fast stain,Myobacterium tuberculous culture in BACTEC MGIT 960, real-time lfuorescent quantitative polymerase chain reaction (FQ-PCR) and modiifed acid fast stain, were used to assay the cerebrospinal lfuid specimens for diagnosis of tuberculous meningitis.ResultsThe positive rate was 11.7% (7/60), 6.7% (4/60), 48.3% (29/60), and 61.7% (37/60), respectively in the study group as tested by the four methods. There was signiifcant difference between the four methods in the positive rate (P< 0.05). Modiifed acid fast stain was more sensitive than the other 3 methods in identifying tuberculous meningitis (P< 0.05). This method also could identify the intracellularM. tuberculosis. All the 8 samples from the 4 patients who were positive for culture ofM. tuberculosis were positive in the modiifed acid fast stain.Conclusions The modiifed acid fast staining method is simple, fast, signiifcantly more senstive in detection of the acid fastM. tuberculosis in CSF, either extracellular or intracellular. It is worthwhile to further investigate its usefulness in early diagnosis of tuberculosis meningitis.

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.
