Bioadhesive delivery systems with sustained release characteristics can promote the absorption and increase the bio-availability of drugs by prolonging the residence time on the applied site. The evaluation of adhesion property of bioadhesive drug deliv-ery systems is important because the sustained release effect and the absorption are closely related with the adhesion. The methods for the evaluation of the adhesive properties of bioadhesive drug delivery systems in vitro were summarized in the article, including determi-ning the minimum peel force, measuring the residues on mucosa surface, determining the retention time on mucosal surface, measuring the swelling and the viscosity of fluid and so on, and the operation of some methods were described simply as well.

This study was aimed to probe into the mechanism of moxibustion in the treatment of Alzheimer’s disease (AD). A total of 40 male 15-month-old SD rats were randomly divided into the normal group, model group, moxibustion group and sham-operation group. Stereotactic injection of agglutinated Aβ25-35 into rat’s bilateral hippocampus was used to prepare AD models. Equal amount of normal saline was injected to rat’s bilateral hippocampus in the sham-operation group. Model rats were treated by moxibustion at the distance of 2-3 cm above points of‘BL23-Shenshu’, ‘ST36-Zusanli’ and ‘GV20-Baihui’. No intervention was given to rats in the normal group. The learning and memory ability was detected by Morris water maze test. Changes on expressions of Bcl-2, Bax and Caspase-3 of hippocampus zone were detected by immunohistochemical method. The results showed that in the model group, the average escape latency of five days and the last three days were significantly lengthened. And the times across the platform position were significantly reduced. Compared with the normal group and the sham-operation group, expressions of Bax and Caspase-3 in the hippocampus were significantly increased, and the expression of Bcl-2 was obviously decreased (P < 0.01). In the moxibustion group, the average escape latency of five days and the last three days were shortened obviously, and the times across the platform position were significantly increased. Compared with the model group, expressions of Bax and Caspase-3 were significantly reduced, and the expression of Bcl-2 was significantly increased (P < 0.01). It was concluded that the action mechanism of AD treatment with moxibustion may be through the reducing of proapoptotic protein Bax and Caspase-3 releasing, promoting the releasing of anti-apoptotic protein Bcl-2, so as to improve the learning and memory impairment caused by Aβ.

Objective To observe the effects of moxibustion on learning and memory ability and nerve cell ultrastructure in CA1 region of hippocampus of rats with Alzheimer's disease (AD);To discuss its mechanism of action to AD.Methods A total of 40 male SD mice was randomly divided into normal group, model group, moxibustion group and sham-operation group. Stereotactic injection agglutinated Aβ25-35 into bilateral hippocampus of rats in model group and moxibustion group to prepare AD models. Rats in moxibustion group were treated by moxibustion at the points which were located above 2-3 cm away from Shenshu, Zusanli and Baihui. Rats in normal group received no treatment. The learning and memory ability was detected by Morris water maze test. Morphological changes of rat nerve cell ultra structure in hippocampal CA1 region were observed by transmission electron microscope.Results In model group, the average escape latency of five days and the last three days was significantly lengthened, and the times across the platform position significantly decreased. Transmission electron microscope indicated nerve cell structures were damaged and displayed unclearly;mitochondrion swelled, even mitochondrial crista was abnormal and deformed, endoplasmic reticulum of inter organelle expanded and the deposition of lipofuscin increased. After the treatment by moxibustion, the average escape latency of five days and the last three days was shortened obviously, and the times across the platform position significantly increased. In moxibustion group, the edema of nerve cells significantly decreased;dilation of endoplasmic reticulum and mitochondria swelling significantly improved;golgi bodies, mitochondria and ribosomes obviously increased in comparison with the model group. Conclusion Moxibustion can improve the learning and memory impairment caused by Aβ by promoting repairing of nerve cells in brain.

Objective: To investigate the effect of phosphocreatine (PCr) on angiotensin II (Ang II) induced proliferation and collagen synthesis of cardiac ifbroblasts in neonatal rats with its mechanism.
Methods: The cardiac ifbroblasts (CF) from neonatal rats were cultured in vitro and were divided into 4 groups.①Control group, the CF was cultured in non-serum DMEM,②Ang II group, the CF was cultured with Ang II at (1×10-6) mol/L,③PCr treated group, the CF was cultured with PCr at 10 mmol/L, and④Ang II+PCr group. The CF cell cycle percentage was detected by lfow cytometric assay, myocardial collagen content was observed by VG staining and protein expression of phosphorylated extracellular signal-regulated kinase (pERK1/2) was detected by immuneohistochemistry.
Results: ① Compared with Control group, the CF in Ang II group showed increased percentage of S phase and decreased percentage of G0/G1 and G2/M phases, increased collagen content and pERK1/2 protein expression, all P<0.01.② The CF cell cycle, collagen content and pERK1/2 protein expression were similar between Control group and PCr treated group, all P>0.05. ③ Compared with Control group, Ang II + PCr group had elevated pERK1/2 protein expression, P<0.01, while the CF cell cycle and collagen content were similar with Control group, P>0.05.④Compared with Ang II group, the CF in Ang II + PCr group had increased percentage of G0/G1 and G2/M phases, decreased percentage of S phase, decreased collagen content and pERK1/2 protein expression, all P<0.01.
Conclusion: PCr may partially inhibit Ang II induced CF proliferation and collagen synthesis which might be related to the inhibition of excessively activated ERK1/2. Therefore, PCr could improve Ang II induced myocardial ifbrosis in neonatal rats.

OBJECTIVETo explore action mechanism of electroacupuncture (EA) on treatment of Parkinson's disease (PD).

METHODSA total of 40 healthy male SD rats were randomly divided into a normal group, a sham operation group, a model group and an EA group, 10 rats in each group. PD rat model was duplicated by micro injection of 6-hydroxyl dopamine into right striatum of rats, and the rats in the sham operation group were treated with micro injection of 0. 9% NaCl. Rats in the normal group, model group and the sham operation group received no treatment; rats in the EA group were treated by EA at "Fengfu" (GV 16) and "Taichong" (LR 3) with continuous wave, 2 Hz in frequency, 1 mA in intensity for 30 min. The treatment was given once a day for total 2 weeks. Behavioral test was used to evaluate rotational behavior changes of PD rats. RT-PCR method was applied to detect the expression of GFAP (glial fiber acidic protein) mRNA and Cx43 (connexin 43) mRNA in the striatum.

RESULTSThe difference of rotational behavior was not significant before and after treatment in the model group (P>0. 05), while that in the EA group was significant (P<0. 01). The expression of GFAP mRNA and Cx43 mRNA in the model group was significantly higher than that in the normal group and sham operation group (all P<0. 01); after EA treatment, the expression of GFAP mRNA and Cx43 mRNA in the EA group was lower significantly than that in the model group (both P<0. 01).

CONCLUSIONThe action mechanism of EA for prevention and treatment of Parkinson' s disease may be associated with inhibiting the activation of astrocytes.
