This study is to investigate the protective effect of rosiglitazone (RSG) against learning and memory impairment of APP/PS1/tau transgenic mice. AD mice model was replicated by using 6-month APP/PS1/tau transgenic mice. The learning and memory ability of mice was evaluated by Morris water maze and Western blotting assays was applied to measure the phosphorylation and O-glycosylation of Tau and neurofilaments (NFs) protein. The results demonstrated that RSG could reverse the learning and memory deficits of 3 x Tg mice significantly. It was also found that RSG could suppress the hyperphosphorylation of Tau and NFs protein levels and increase the glycosylation expression of Tau and NFs proteins in 3 x Tg mice brain. Together, RSG ameliorates cognitive impairments of 3 x Tg mice via the alleviation of the hyperphosphorylated Tau and NFs proteins burden in the brain.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.

METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.

RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.

CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.

AIMThe liposome/water partition coefficients of salmeterol and budesonide between aqueous phase and liposomes were determined and the factors that influence their partition coefficients were studied, the mechanism of interaction between the two drugs and phospholipid bilayer was elucidated.

METHODSThe liposome/water partition coefficients of the two drugs were determined by equilibrium dialysis technique. The change of the partition coefficients of the two drugs along with liposome composition and medium was also studied.

RESULTSThe partition coefficients of the two drugs decreased with the increase of cholesterol content and saturation of phospholipid used. The liposome/water partition coefficient of salmeterol increased with the increase of liposome surface negative charge, medium pH and ionic strength, while the liposome surface charge, medium pH and ionic strength had no distinct effect on the liposome/water partition coefficient of budesonide.

CONCLUSIONThe liposome/water partition coefficient of drug was affected by the type, saturation of phospholipid used in liposome preparation, the cholesterol content and surface charge of liposome, as well as the pH and ionic strength of medium also have effect on the liposome/water partition coefficient of drug. Accordingly, in order to reflect the actual partition of drug in biological membrane, the determination condition including liposome composition and medium should be similar to the biological membrane.

OBJECTIVETo observe the local tissue oxygenation in acupoint Zusanli (ST36) of patients in critical condition, and to assess the value of applying tissue oxygen measurement via acupoint in clinical practice.

METHODSThirty-six patients with severe illness undergoing invasive positive pressure ventilation (IPPV) were divided into the infected group (n=13) and the non-infected group (n=23). Tissue oxygen pressure (PtO2) in the right acupoint Zusanli was measured with tissue oxygen tension detector when the concentration of inspired oxygen (FiO2) was 40% and 100% respectively, meanwhile, the arterial blood oxygen pressure (PaO2) was also determined to calculate PtO2 index (the ratio of PtO2/PaO2).

RESULTSThere was a positive correlation between PtO2 and PaO2 (P < 0.05); PaO2 in the infected group was lower, and PtO2 index and PtO2 were higher significantly, as compared with those in the non-infected group (all P < 0.05). As FiO2 adjusted from 40% to 100%, the increment of PtO2 in the infected group was significantly higher than that in the non-infected group (P < 0.05).

CONCLUSIONFor the severely infected patients with obstacle of systemic oxygen delivery, the local tissue oxygen demand of acupoints increases significantly, and the tissue oxygen delivery dependence is enhanced, in this time, the tissue might fulfill the oxygen demand itself through elevating PtO2 index. It is of great significance to monitor tissue oxygen pressure in acupoint to determine the state of local tissue oxygenation in critically illed patients.
