ABSTRACT
Objective:To observe the protective effect of Angong Niuhuang pill on brain function of rats with sepsis, explore its protective mechanism, and provide the experimental basis for clinical application of Angong Niuhuang pill in the treatment of sepsis-associated encephalopathy (SAE).Methods:Thirty male Sprague-Dawley (SD) rats were divided into sham operation group, sepsis model group and Angong Niuhuang pill group according to random number table method, with 10 rats in each group. The sepsis model was established by cecal ligation and puncture (CLP); rats in sham operation group received open and closed abdomen. The rats in the Angong Niuhuang pill group were given Angong Niuhuang pill (0.3 g/kg) by gastric irrigation daily for 3 days before CLP, and the drugs were administrated 12 hours after modeling again. After 24 hours of CLP, the neuroreflex scores were evaluated, white blood cell count (WBC), the levels of serum neuron-specific enolase (NSE) and S100β were detected. Then the brain tissue was harvested. After hematoxylin-eosin (HE) staining, the pathological changes of brain tissue were observed under the light microscope. The mRNA expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in brain tissue were detected by polymerase chain reaction.Results:Compared with the sham operation group, the total score of neuroreflex scores in the sepsis model group and the Angong Niuhuang pill group were significantly reduced (4.43±1.40, 6.57±1.90 vs. 9.40±0.84, both P < 0.05), WBC, serum NSE, S100β were significantly increased [WBC (×10 9/L): 8.07±1.32, 5.84±0.94 vs. 3.60±0.32; NSE (μg/L): 1.04±0.14, 0.61±0.07 vs. 0.16±0.04; S100β (ng/L): 255.624±30.25, 97.72±15.41 vs. 46.88±12.03, all P < 0.05], and the mRNA expressions of IL-6 and TNF-α in brain tissue were significantly increased [IL-6 mRNA (2 -ΔΔCt): 5.668±2.195, 3.605±1.014 vs. 0.997±0.329; TNF-α mRNA (2 -ΔΔCt): 18.996±0.913, 1.746±0.710 vs. 0.674±0.132, all P < 0.05]. Compared with the sepsis model group, the total score of neuroreflex scores in the Angong Niuhuang pill group was significantly increased (6.57±1.90 vs. 4.43±1.40, P < 0.05), WBC, serum NSE, S100β concentration, and the mRNA expressions of IL-6 and TNF-α in the brain were significantly reduced [WBC (×10 9/L): 5.84±0.94 vs. 8.07±1.32, NSE (μg/L): 0.61±0.07 vs. 1.04±0.14, S100β (ng/L): 97.72±15.41 vs. 255.62±30.25, IL-6 mRNA (2 -ΔΔCt): 3.605±1.014 vs. 5.668±2.195, TNF-α mRNA (2 -ΔΔCt): 1.746±0.710 vs. 18.996±0.913, all P < 0.05]. Brain histopathological observation showed that the hippocampal neurons in the sepsis model group were disordered arrangement, a large number of neuronal nuclei were contracted, and the tissue was loose with obvious edema. Compared with the sepsis model group, the Angong Niuhuang pill group had less nuclear shrinkage and tissue edema. Conclusions:The pretreatment of the Angong Niuhuang pill can improve the brain dysfunction of septic rats and reduce the expression of pro-inflammatory cytokines in the brain. It is speculated that the Angong Niuhuang pill can protect the brain function in sepsis by inhibiting the inflammatory reaction in the brain.

ABSTRACT
Objective To observe the therapeutic effect and prognosis of patients with severe traumatic craniocerebral injury treated by Lund program combined with Angong Niuhuang pill. Methods A prospective study was conducted. Forty-nine patients with severe traumatic craniocerebral injury were divided into two groups:combined treatment group (25 cases) and control group (24 cases). All the patients in the two groups received conventional therapy. Additionally, the combined treatment group was treated by the Lund program combined with Angong Niuhuang pill, the patients after admission into the intensive care unit (ICU), indwelling of gastric tube was immediately given (the tube inserted and retained through mouth in cases with cranial base bone fracture), one pill of Angong Niuhuang was fed nasally twice a day for consecutive 15 days. Before and after treatment, the intracranial pressure (ICP), cerebral perfusion pressure (CPP), Glasgow coma scale (GCS) score, the mean flow velocity of middle cerebral artery (MCA), and the incidence of complication, clinical efficacy and prognosis in the two groups were observed. Results There were no statistically significant differences in the levels of ICP, CPP, GCS score and the average flow velocity of MCA before treatment and the first day after treatment between the two groups. Beginning from 3 days after treatment, the degrees of improvement in the above indexes in the combination treatment group became much better than those in the control group [ICP (mmHg, 1 mmHg=0.133 kPa):16.78±4.50 vs. 18.80±5.67, CPP (mmHg):71.35±1.63 vs. 58.11±1.47, GCS score:9.53±0.38 vs. 8.23±0.44, the mean blood flow velocity (cm/s):152.23±3.33 vs. 178.86±5.23, all P0.05). The rate of good therapeutic effect in combination treatment group was obviously higher than that of the control group [72.0% (18/25) vs. 33.3% (8/24), P < 0.05], while the mortality was markedly lowered [8.0% (2/25) vs. 33.3% (8/24), P < 0.05]. Conclusions The combination of Lund program and Angong Niuhuang pills for treatment of patients with severe traumatic craniocerebral injury can reduce the degree of increase of ICP at early stage, ameliorate cerebral edema and its development, elevate CPP and improve cerebral ischemia and hypoxia. In the aspects of controlling hyperpyrexia, decreasing limbs twitches and the incidence of hernia, elevating the quality of patients' life, reducing mortality and improving prognosis, the therapy has relatively good therapeutic effects.

ABSTRACT
OBJECTIVE To validate the anticancer effect of Angong Niuhuang pill (AGNH) and pinpoint associated molecular mechanisms using human cancer cells.METHODS Human MGC-803 gastric carcinoma and human BEL-7402 hepatocarcinoma cells were incubated with AGNH 9,30,90,300 and 900 mg·L-1 for 24,48and 72 h,respectively.Cell viability was detected with 3-(4,5-dimethylthiazol-2-yl) -5-( 3-carboxymethoxyphe-nyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay and colony formation assay.Apoptosis was measured with flow cytometry and Hoechst 33258/PI staining.Change in mitochondrial membrane potential (△qψ) was detected by spectrofluorophotometer.RESULTS AGNH inhibited MGC-803 cell proliferation ( for 48 h,r =0.996,P =0.002; for72 h,r=0.756,P=0.024 ) and BEL-7402 cells (for 48 h,r =0.732,P=0.030; for72 h,r=0.702,P =0.037) in a concentration-dependent manner,as showed by MTS assay.AGNH inhibited colony formation on MGC-803 cells (r =0.914,P =0.011 ) and BEL-7402 cells (r =0.871,P =0.024) in a concentration-dependent manner for 24 h.Hoechst 33258/PI staining and flow cytometry assay showed that AGNH 900 mg·L-1 for 24 h induced apoptosis of MGC-803 and BEL-7402 cells,and the apoptosis rate was 27.2％ and 19.7％,respectively.Compared with normal control group,AGNH 900 mg·L-1 for 3 min decreased the mitochondrial membrane potential of MGC-803 and BEL-7402 cells to 15.9％ and 15.0％ of control group.CONCLUSION AGNH inhibits proliferation of human cancer cells.Apoptosis and depolarization of mitochondrial transmembrane potential are probablly its mechanism.
ABSTRACT
AIM:To evaluate the actions of cinnabaris and realgar in arousing brain and opening the orifices of Angong Niuhuang Pill,and to provide experimental basis for the rationality of Angong Niuhuang Pill buildup. METHODS: The brain damage model was made by LPS injection through caudal vein.With quantitative electroencephalogram of medicine methods,effects of Angong Niuhuang Pill,Angong Niuhuang Pill without cinnabaris and realgar,cinnabaris,realgar on the power and relative power of delta and beta waves of electrocorticogram(ECoG) were observed in the brain damage rats caused by LPS. RESULTS: LPS could increase the power and the relative power of the delta waves(0.5-3 Hz),and reduce the power and the relative power of the beta waves(14-30 Hz).All medicines could reduce the power and the relative power of the delta;Angong Niuhuang Pill,cinnabaris and realgar,realgar could increase the power and the relative power of the beta,cinnabaris could increase the relative power of the beta(14-30 Hz),and Angong Niuhuang Pill without cinnabaris and realgar could not. CONCLUSION: Angong Niuhuang Pill has obvious activation on ECoG,and same as cinnabaris and realgar.The results of the present work allow us to put forward the hypothesis that cinnabaris and realgar are most likely one of the important material basis in arousing brain and opening the orifices of Angong Niuhuang Pill.
