China Journal of Chinese Materia Medica 2014;39(13):2564-2568
OBJECTIVETo observe the effect of Xingnaojing Injection combined with minimally invasive percutaneous drainage on brain edema and content of serum aquaporin-4 (AQP4) in patients with moderate hypertensive basal ganglia hemorrhage, and discuss the treatment mechanism of Xingnaojing injection combined with minimally invasive percutaneous drainage for cerebral hemorrhage.
METHODForty-two patients with moderate (25-50 mL) hypertensive basal ganglia hemorrhage (< 24 h) were selected and randomly divided into two groups: the observation group (n = 22) and the control group (n = 20). The neurological severity score were evaluated by the NIHSS (national institutes of health stroke scale), the volume of brain edemas were measured by head CT, the serum levels of AQP4 were determined by ELISA method on admission and 1 and 2 weeks after treatment.
RESULTOn admission, there was no significant difference in the scores of NIHSS, the volume of brain edemas and the level of serum AQP4 between the observation group and the control group. At the end of the first week after the treatment, the score of NIHSS of the observation group were lower than that of the control group, with significant different (P < 0.05); the observation group showed reduced volume of brain edemas than that on admission (P < 0.05), whereas the control group the control group showed increased volume of brain edemas than that on admission; the control group displayed increased level of serum AQP4 than that on admission, but without significant difference; the observation group displayed decreased level of serum AQP4 than that on admission (P < 0.05). At the end of the second week after the treatment, the control group showed decreased score of NIHSS than that on admission and at the end of the first week after treatment (P < 0.05). Compared with the control group, the observation group showed a much lower score of NIHSS (P < 0.01), the control group displayed reduced volume of brain edemas than that on admission and at the end of the first week after treatment, but the observation group was even lower than the control group. Both of observation and control groups displayed significantly reduced level of AQP4 (P < 0.05), but the observation group showed a lower AQP4 level than that of the control group (P < 0.05).
CONCLUSIONThe therapy of Xingnaojing injection combined with minimally invasive percutaneous drainage could remarkably reduce brain edema, and promote neural functional recovery, thus could be selected as a therapeutic regimen for patients with moderate hypertensive basal ganglia hemorrhage.

OBJECTIVE Recent studies have demonstrated that the Nlrp3 inflammasome serve as a central role in the pathogenesis of cardiovascular diseases and endothelial dysfunction occurs in association with several cardiovascular risk factors. Given the demonstrated anti-inflammatory effects of aspirin, the present study was designed to test whether aspirin diminish NLRP3 inflammasome activation and prevent endothelium injury and associated coronary artery damage during LPS. METHODS Mouse carotid arterial endothelial cells (CAECs) were cultured and treated with 0.1-3 mmol·L-1 of aspirin in response to LPS (2 μg·mL-1) stimuli. After 24 h, the Nlrp3 inflammasome complexes consist of varied proteins were analyzed by WB. NO and T-AOC in the supernatant was detected by ELISA. Intracellular reactive oxygen species (ROS) generation for 24 h was observed by DCF fluorescence. The mice were treated with aspirin (12.5 mg·kg-1 per day, 62.5 mg·kg-1 per day, 125 mg·kg-1 per day) and dexametha?sone (0.0182 mg · kg- 1 per day) for 7 d. The level of IL- 1β,IL- 18 protein was detected by ELISA. RESULTS Immunofluorescence results showed the colocalization of Nlrp3 with ASC or caspase 1 decrease in a concentration- dependent manner. Meanwhile, the expression of Nlrp3 and caspase 1 protein was decreased with the concentration of aspirin, but no changes the expression of ASC protein. Nlrp3 protein levels in CAECs were 0.33- 0.8- fold and cle- caspase 1 protein levels in CAECs were 0.48-1-fold compared to those in LPS stimulation when treated with 0.1-3 mmol·L-1 aspirin for 24 h (P<0.01). Aspirin significantly antagonized the effect of LPS on NO (1.22-1.91-fold that of LPS stimulation, P<0.01) and T-AOC expression (1.02-1.90-fold that of LPS stimulation, P<0.01). As the different concentration of aspirin treated, the generation of ROS was 0.51-1.10-fold that of LPS stimulation (P<0.01). In vivo data shown the level of IL-1β, IL-18 protein from serum are in concordance with the level of Nlrp3 inflammasome activation. CONCLUSION We conclude that aspirin has anti- inflammatory properties, protecting CAECs from LPS-induced injury by inhibition of NLRP3 inflammasome activation through ROS pathway.

Objective To investigate the efficacy and safety of citrate anticoagulation for continuous renal placement therapy (CRRT) in patients at high risk of bleeding. Methods Forty-seven patients who needed to CRRT and were admitted into the department of critical care medicine from January 2015 to October 2016 were enrolled in this study. According to the patient′s actual condition, they were divided into citrate groups (24 cases) and saline group (23 cases). Patients in saline group were given saline wash. The efficacy and safety were compared between the two groups. The filter lifetime, after treatment the activated partial thromboplastin time (APTT), hemoglobin (Hb), blood gas indexes were compared between the two groups. Results The citrate group used 76 filters while the 0.9% sodium chloride group used 87 filters. The average filter lifetime in citrate group was (22.4 ± 12.7) h which was longer than (8.6±3.3) h in 0.9%sodium chloride group (t=9.79, P<0.01). The incidence of coagulation in extracorporeal circulation was 3.9%(3/76) which was lower than 16.1%(14/87) in 0.9%sodium chloride group(χ2=5.20, P<0.05). Conclusions Regional citrate anticoagulation is a safe and effective option for CRRT in patients at high risk of bleeding.
