Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.

Objective: To observe the effect of Rosiglitazone (RGTZ) on oxygen free radical and biochemical parameters of aged rats, so as to establish a basis for anti-aging study. Methods: The 24-month-old naturally aged SD rats were randomly divided into the control group (CONT), the RGTZ group and the caloric restriction group(CR). The RGTZ group was given intragastric administration of RGTZ (4 mg · kg-1 · d-1) and the CR group was given 60% of the diet that of the CONT group. The rats were killed 12 weeks later and the serum malondialdehyde(MDA) content, superoxide dismutase(SOD) activity and the blood biochemistry parameters were examined. Results: The blood glucose (GLU), aspartate transaminase (AST), alamine transaminase(ALT), serum creatinine (SCr), and blood urea nitrogen (BUN) were within the normal range in all groups. Compared with the CONT group, blood cholesterol (CH) in RGTZ group was lower, but with no significant difference. The serum triglyceride(TG) of both RGTZ and CONT groups decreased markedly than those in the CONT group(P<0.05). The activities of SOD and MDA were improved in RGTZ and CR group compared with the control group. Conclusion: RGTZ can regulate the lipid metabolism and attenuate the oxidative damage in aged rats, indicating its anti-aging effect.

Objective: To investigate the expression of peroxisome proliferator-activate receptor γ(PPARγ) in the kidneys of rats at different ages, so as to study the possible association of PPARγ expression with oxidative stress in the aging process. Methods: Rat aging model was established using 3-, 12-, and 24-month old rats. Western blotting was used to determining the protein expression of PPARγ. The changes anti-oxidative ability of renal tissue were studied by determining the activities of superoxidedismutase(SOD) and glutatio-neperoxidase(GSH-PX). Results: Western blotting assay showed that the renal expression of PPARγ protein decreased with the aging of rats,with that of 3-month group significantly higher than that of the 24-month group(P<0.01). The activities of SOD and GSH-PX deceased with the aging of rats(P<0.01). Both the SOD activities were positively correlated with the expression of PPARγ protein(r=0.90, r=0.89, P<0.01) Conclusion: Renal PPARγ has a decreasing tendency during the aging process of rats, which is correlated with the down-regulation of anti-oxidative ability of renal tissue.

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 P<0.05]. The incidences of complications such as hyperpyrexia [8.0%(2/25) vs. 41.7%(10/24)], hyperspasmia [12.0%(3/25) vs. 45.8%(11/24)] and cerebral hernia [8.0%(2/25) vs. 33.3%(8/24)] in the combined treatment group were significantly lower than those in the control group (all P < 0.05). The rates of renal failure, electrolyte imbalance and pulmonary infection in combined treatment group were also lower than those in the control group, but the differences were not statistically significant (all P>0.05). 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.

Objective This study is to identify the presence of superoxide anion-generating system in human lens epithelial cells using arachidonic acid (AA) as the stimulator.Design Experimental study.Participants Human lens epithelial cells B3 (HLE B3). Methods Confluent human lens epithelial cells (HLE B3) were subjected to stimulation by AA and its derivatives.The generation of su- peroxide anion was quantified with a luminometer (LumiStar BMG) immediately upon AA and its derivatives addition.Cells preloaded with superoxide dismutase (SOD) or mannitol were used as negative controls and cells mixed with 3% ethanol (solvent for AA) were used as baseline.Cells were preloaded with inhibitors 30 minutes before luminometer measurement.A time-and concentration-depen- dent study on the AA-stimulated activation of mitogen-activated protein kinase (MAPK) was carried out using western blot analysis. Main Outcome Measures Superoxide generation,phosphorylation of MAPK.Results AA at dosage of 30-150 mM proportionally in- duced luminescence in HLE B3 cells,but was ineffective in cells preloaded with SOD or mannitol.DPI,a non-specific NADPH oxidase inhibitor eliminated AA-induced superoxide anion generation partially.Leinoleic acid,stearic acid,eicosa-11Z,14Z,17Z-trienoic acid (20:3) and eicosa-11Z,14Z-dienoic acid (20:2) were ineffective.The generation of superoxide anion was not contributed by cyclooxyge- nase or the cytochrome p450 pathway since indomethacin (inhibitor for cyclooxygenase) or ketoconazole (inhibitor for cytochrome p450) could not eradicate the stimulatory effect of AA.While CDC,a specific inhibitor for lipoxygenase could eliminate superoxide generation partially.The specific inhibitor for 5-lipoxygenase AA861 completely blocked the generation of superoxide anion.Western blot analysis of the cell lysate showed that AA at the concentrations of 30-150 mM progressively activated ERK and JNK.They were transiently ac- tivated between 2.5-30 minutes.The activations of ERK and JNK were dose-dependent and time-dependent.Conclusions Inhibition of superioxide anion generation may be a new approach to block lens epithelial cell proliferation and post-capsule opacification.
