Chinese Journal of Trauma 1990;0(04):-
Objective To investigate the effects of ?-aescin on nuclear factor-?B (NF-?B) activities and tumor necrosis factor-? (TNF-?) protein expression in the rat brain tissue following acute traumatic brain injury (TBI). Methods A total of 62 SD rats were subjected to a lateral cortical impact injury caused by a free-falling object and divided randomly into four groups, ie, sham operation group (Group A), injury group (Group B), ?-aescin treatment group (Group C) and pyrrolidine dithocarbamate (PDTC) treatment group (Group D). Group C was administered with ?-aescin and Group D treated with PDTC immediately after injury. A series of brain samples were obtained directly 6, 24 hours and three days respectively after operation in four groups. The NF-?B activation of rat brain was determined by electrophoretic mobility shift assay (EMSA) and the levels of TNF-? protein in rat brain measured by radio-immunoassay (RIA). In the meantime, the water content of rat brain was measured and pathomorphological observation carried out. Results Compared with Group A, NF-?B activities, the levels of TNF-? protein and the water content of the rat brain were significantly increased (P

6.Research advances in the pathogenesis of pediatric parenteral nutrition associated cholestasis
Chinese Journal of Clinical Nutrition 2010;18(1):48-51
Parenteral nutrition associated cholestasis (PNAC) mainly occurs in children. Currently identified risk factors include premature infants, lack of enteral feeding, repeated infections, and toxicity or nutrient deficiency of parenteral nutrition solution. Recent studies have shown that nuclear receptor-mediated bile acid transporter may be the key site of PNAC pathogenesis, in which some cytokines play important roles. New anti-cholestatic therapy based on the regulation of expression of these molecules may prevent end-stage liver disease caused by PNAC.

Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2015;22(3):291-294
Objective To investigate the therapeutic effect of bundle treatments for critically ill patients with pulmonary tuberculosis and respiratory failure (RF).Methods A prospective study was conducted, including 56 patients with pulmonary tuberculosis and RF necessary for invasive mechanical ventilation admitted into Department of Critical Care Medicine of the Fourth People's Hospital of Nanning City from January 2013 to December 2014 as the observation group to be treated by bundle treatments. A series of treatments and cares were given to the critically ill patients, such as invasive mechanical ventilation, application of antibiotics by experience within the first hour, supportive treatment targeted to hemodynamics in early stage, correction of brain dysfunction, effective therapy for tuberculosis, establishment of enteral nutrition in early stage and prevention of ventilator-associated pneumonia (VAP), etc. All the above treatments were completed one by one in 6 hours to 12 hours. Meanwhile, 42 patients who hospitalized from January 2011 to December 2012 and treated with conventional targeted therapy were designed as the control group. The changes of vital signs, blood routine test, respiration, liver, kidney, etc organ functions, the improvement of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, expected mortality and sequential organ failure assessment (SOFA) score, the incidence of VAP, cure and improvement rate, mortality, duration of invasive mechanical ventilation, the length of stay in intensive care unit (ICU) were compared between the two groups after treatments.Results There were no statistically significant differences in the comparisons between the two groups before and after treatments in temperature, white blood cell count (WBC), blood glucose, total bilirubin (TBil), alanine transaminase (ALT), albumin (Alb) and cholesterol level (allP > 0.05), except the platelet (PLT) count in observation group was higher than that in control group before treatments. After treatments for 72 hours, in the two groups, the heart rate (HR), respiration rate (RR), APACHE Ⅱ score and expected mortality were lower than those before treatments, while the arterial partial pressure of oxygen (PaO2) and oxygenation index were higher than those before treatments. There were no statistically significant differences in pH value, PLT, arterial partial pressure of carbon dioxide (PaCO2) and SOFA score before and after treatments in the control group (allP > 0.05). In the observation group, after treatments, the pH value was increased compared with that before treatments, while PLT, PaCO2 and SOFA score were decreased compared with those before treatments (allP < 0.05). The degrees of improvement of PaCO2 and oxygenation index in the observation group were superior to those in the control group [PaCO2 (mmHg, 1 mmHg = 0.133 kPa): 43.32±9.10 vs. 56.10±9.39, oxygenation index (mmHg): 330.60±100.98 vs. 245.65±83.20, bothP < 0.05]. After bundle treatments, compared with control group, the incidence of VAP was decreased [16.07% (9/56) vs. 33.33% (14/42),P < 0.05], improvement and cure rate was increased [78.57% (44/56) vs. 59.52% (25/42),P < 0.05] and mortality was decreased significantly in observation group [10.71% (6/56) vs. 28.57% (12/42),P < 0.05]. The duration of invasive mechanical ventilation (days: 9.15±3.59 vs. 16.96±13.44) and the length of stay in ICU (days: 13.30±4.24 vs. 23.00±15.03) in the observation group were shorter than those in the control group, but no statistically significant differences were found (bothP > 0.05).Conclusion The bundle treatments can effectively reduce the incidence of VAP and elevate the improvement and cure rate in patients with pulmonary tuberculosis complicated with RF.
