Objective To observe the effects of pituitary adenylate cyclase-activating polypeptide (PACAP) on the expressions of caspase-3 and X-linked inhibitor of apoptosis protein (XIAP) after hypoxic-ischemic brain damage (HIBD) in neonatal rats and to investigate its neuroprotection and effective dose. Methods Sixty neonatal rats were randomly allocated to one of three groups: sham operation, saline control and PACAP groups. The PACAP group was redivided into high (10-8 mol), medium (10-9 mol) and low (10-12 mol) dose groups. An animal model of HIBD was established. Real-time fluorescent quantitative polymerase chain re-action method was used to detect the expressions of caspase-3 mRNA and XIAP mRNA on af-fected side of brain 24 hours after HIBD in neonatal rats, and spectrophotometry was used to detect the activities of caspase-3. Results Twenty-four hours after HIBD, caspase-3 mRNA expression and enzyme activity, as well as XIAP mRNA expression in the saline control group were increased significantly compared to the sham operation group (all P <0.01). Caspase-3 mRNA expression and enzyme activity in all the PACAP groups were significantly lower than those in the saline control group (all P <0.01), while XIAP mRNA expression was significantly higher than that in the saline control group (all P < 0.01 ). Conclusions PACAP may upregu-late XIAP mRNA expression, inhibit caspase-3 mRNA expression and enzyme activity. It has neuroprotective effect on HIBD in neonatal rats, and it is effective with high, medium and low doses.

Objective To study the effects of the BanxiaXiexin decoction (BD) on express of glycogen synthesis and the expression of MC4R.and to discuss the mechanism of its maintaining glucose metabolism balance.Methods Diabetic mice were induced and divided into the model group,metformin group(0.3 g/kg)and BD high dose group(1.7 g/kg),medium dose group(0.85 g/kg),and low dose group (0.425 g/kg).In addition,a normal group was set to feed normal diet.Fasting blood glucose,body weight on an empty stomach,express of MC4R and hepatic glycogen were assayed after a week of treatment.Results Body weight of BD high,medium and low dose group was (296.62 ±1.14) g,(293.83 ± 2.1 7 ) g,and (286.75 ± 1.91 ) g respectively,showing a significant increase compared with the model group (284.73± 2.91) g (P＜0.01).MC4R expression of these MD groups were (29.69 ± 1.64) ng/L,(29.38±1.88) ng/L and (30.04 ±1.24) ng/L,showing a significant increase compared with the model group (25.95±2.24) ng/L (P＜0.05).Liver glycogen content of these MD groups were (15.94±0.82)mg/g,(11.52±0.56)mg/g,and (10.48±0.45)mg/g respectively,also showing a significant increase than the model group (9.05±0.44)mg/g(P＜0.01,P＜0.01,P＜0.05).Conclusion BD improves MC4R expression and rat feeding behavior by increasing by peripheral organization utilization of glucose.

Objective:To explore the impact of clinical pharmacists involved in the treatment team on the reasonable drug use rate in medical orders. Methods:Totally 782 medical records including hypertension and 1-3 kinds of hypertension associated diseases in our hospital from January 2011 to December 2011 were used as the pre-intervention group, and 1 061 ones with the same conditions from September 2012 to August 2013 were used as the post-intervention group. The patients of the two groups were divided into 8 dis-ease subgroups, clinical pharmacists performed timely intervention on the medical orders in the post-intervention group, and the rational drug use rate between the two groups was compared. Results:In hypertension, hypertension associated coronary heart disease, hyper-tension with heart failure and hypertension with diabetes subgroups,the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 01), in hypertension with coronary heart disease and heart failure, hypertension associ-ated coronary heart disease and diabetes, hypertension with heart failure and diabetes subgroup, the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 05), while in hypertension with coronary heart disease, heart failure and diabetes subgroups, the difference was not statistically significant(P>0. 05). After the medical records in the 8 sub-groups were aggregated, the difference in the rational drug use proportion before and after the intervention was statistically significant( P<0. 01). Conclusion:Clinical pharmacists should involve in the clinical treatment to intervene irrational drug use,which can signifi-cantly improve the medical record rationality, avoid the health risks as much as possible and ensure the medication safety and treatment effectiveness for patients.

The aim of this study is to synthesize the ordered mesoporous silica (OMS) as drug carrier to improve release property of insoluble drug and investigate the dissolution profile of insoluble drug from the porous carrier. The OMS was obtained by using cetyltrimethyl ammonium bromide as the template and resveratrol was selected as the model drug. The resveratrol-loaded OMS (Res-OMS) were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption, X-ray diffraction (XRD) and FT-IR spectroscopy. In vitro drug release behavior was also investigated. It was found that the synthesized OMS showed a large surface area, a narrow pore size distribution and an important mesoporosity associated to hexagonally organized channels. Compared with physical mixture and crystalline powder, resveratrol was in amorphous or molecular form after loading into OMS. The release rate ofresveratrol from drug-loaded OMS was significantly increased suggesting the great potential application of OMS for the formulation of poorly soluble drugs.

Objective To analyze the characteristics and significance of matrix metalloproteinase-9 (MMP-9) expression in the pathophysiological processes of tuberculous meningitis in mice.Methods Sixteen mice were intracerebroventricularly injected with H37RV suspension as the model group.Meanwhile,the other 16 mice were injected with 0.9％ sodium chloride solution as the control group.Thirty days later,all mice were decapitated and the brain tissue were respectively used to for Mycobacterium tuberculosis (M.tuberculosis) incubation,pathological changes observation,MMP-9 activity detection by zymography,blood-brain-barrier permeability and moisture content detection,and immunofluorescence stain of MMP-9,glial fibrillary acidic protein (GFAP) and integrin αM (OX-42).The t test was used to compare the differences between the two groups.Results Every experimental mouse was injected with (1.271±0.111) × 106 colony-forming units (cfu) M.tuberculosis.Thirty days later,the amount of M.tuberculosis in brain tissue homogenates was (4.900± 1.407) × 104 cfu/mL,and the hematoxylin and eosin staining showed dilatation of subarachnoid and ventricular and infiltration of a large number of inflammatory cells.The cumulative absorbance (A) of MMP-9 bands of brain tissue was 47 821 ± 19 932 in the model group and 10 082 ± 3 544 in the control group.The difference was statistically significant (t =3.728,P=0.010).The evans blue (EB) content of brain tissue was (11.8 ± 3.6) μg/g in model group and (4.7 ±3.4) μg/g in control group.The difference was statistically significant (t=2.887,P=0.028).The moisture of brain tissue was 0.849±0.035 in model group and 0.775±0.037 in control group.The difference was statistically significant (t=2.925,P=0.026).The immunofluorescence staining showed that the infected brain tissue expressed high degrees of MMP-9,GFAP and OX-42.And MMP-9 was overlapped with both GFAP and OX-42 obviously.Conclusions The activity of MMP-9 is significantly enhanced in brain tissue of mice suffering from tuberculous meningitis and participates in blood-brain barrier damage,tissue edema and inflammatory cells exudation.Microglia cells-astrocytes network is involved in the secretion of MMP-9.
