Sustained release drug delivery from microparticles is an excellent alternative for daily protein/peptide drug administration protocol. Poly(lactic acid) (PLA) and poly(lactic-co-glycolic acid) (PLGA) are the most commonly used polymer carriers in the development of protein/peptide microspheres. Basically there are three preparation methods for PLA/PLGA microspheres: the solvent extraction/evaporation based multiple emulsion (W/O/W emulsion) method, the phase separation method and the spray drying method. The stability of the protein/pipetide loaded, encapsulation efficiency, and the burst effect of the microspheres are key problems usually met in the preparation of microspheres. In this review the preparation techniques and progress in the development of protein/pipetide microspheres which aimed to stabilize protein/peptide structural integrity, keep the bioactivity of drugs, increase the encapsulation efficiency and improve the release profile were summarized and evaluated.

Objective To study the effectiveness of EEG bio-feedback in ameliorating the attention of children with attention deficit/hyperactivity disorder (ADHD) compared to a control group receiving methylphenidate treatment; and to explore the effectiveness of EEG bio-feedback in treating ADHD children refractory to methylphenidate. Methods Forty-four ADHD children were randomly assigned to an EEG bio-feedback group or a methylphenidate group. An additional twenty ADHD children refractory to methylphenidate were referred to as EEG bio-feedback group B. The two EEG bio-feedback groups received training in enhancing their beta activity and suppressing their theta activity. The methylphenidate group were treated with methylphenidate for 3 months. The subjects′ attention stability was measured using a number cancellation test. Their attention allocation and attention shift were tested using a neuropsychological behavioral test instrument, including trail-making test. All groups received re-tests during treatment, post-treatment and during a 6 month follow-up. Results During treatment, the cancellation speed of children in the EEG bio-feedback group A was slower than that of children in the MPH group. At the end of the treatment, there were no significant differences in speed between the two groups. Six months to one year after treatment the cancellation speed of the EEG bio-feedback group A was significantly faster than that of the MPH group. The EEG bio-feedback group B demonstrated significant increases in their cancellation speeds after 20 treatments and during a 1 year follow-up. During treatment and post-treatment, Q scores were significantly lower in EEG bio-feedback group A than in the methylphenidate group. Six months to one year after treatment the Q scores were significantly higher in EEG bio-feedback group A than in the methylphenidate group. There was no significant increase in the Q scores in EEG bio-feedback group B during treatment, but they increased significantly post-treatment. There was no significant difference in the trail-making time between EEG bio-feedback group A and the methylphenidate group during the treatment. Six months to one year after treatment, the trailmaking times in EEG bio-feedback group A were significantly less than in the MPH group. EEG bio-feedback group B showed significant decreases in trailmaking time post-treatment and during follow-up. Conclusions EEG bio-feedback may produce significant and long-term improvements in attention stability, attention allocation and attention shift. EEG bio-feedback may be useful for children with ADHD when methylphenidate is ineffective.

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 investigate the myocardial protection of adiponectin (ADP) /adiponectin receptor 1 (ADPR1) related-signal pathway in rats with limb ischemic preconditioning.Methods Thirty SD male rats were randomly divided into sham-operation group,myocardial ischemia reperfusion injury (MIRI) group,limb ischemic preconditioning (LIPC) group,LY294002 (the PI3-specific inhibitor) pretreatment group and LY294002+LIPC group (n=10 each).The mRNA level of myocardial ADP and ADPR1,the protein expressions of phosphatidylinositol 3-kinase (PI3k)phosphorylated Akt (p-Akt) were determined by RT-PCR and Western blot,respectively. Results As compared with sham-operation group,the mRNA levels of ADP and ADPR1 in MIRI group were significantly decreased (0.53 ± 0.07 vs.0.74 ± 0.08 and 0.52 ± 0.02 vs.0.72 ± 0.04,P＜0.05).Compared with MIRI group,the mRNA levels of ADP (0.72±0.21) and ADPRI (0.80±0.023) in LIPC group were increased,ADP(0.49±0.07) and ADPR1 (0.52± 0.02) mRNA were decreased in LY294002 group (both P＜0.05),but there were no difference in ADP(0.70±0.16) and ADPR1(0.78±0.05) mRNA between LY294002+LIPC group and MIRI group.The protein levels of Pl3k and p-Akt were lower in MIRI group than in sham-operation group (3.85±0.23 vs.2.83±0.22and 3.77±0.32 vs.2.66±0.29,P＜0.05).In contrast to MIRI group,the yield of PI3k (2.65±0.32)and p-Akt(2.26±0.27) protein (P＜0.05) were increased in LIPC group,but there were unproductive protein of PI3k (3.75 ± 0.65) and p-Akt (4.01 ± 0.71) in LY294002 group with no differences versus the levels of PI3k (3.23 ± 0.48) and p-Akt (3.17 ± 0.54) in LY294002 + LIPC group. Conclusions Limb ischemic preconditioning may protect myocardium by promoting serum adiponectin levels,improving myocardial mRNA expressions of ADP and ADPR1,activating the ADP/PI3k/Akt signaling pathway in reperfusion injury.

OBJECTIVE:To study the inhibition effects of tranilast on hypertrophic scar tissue of rabbits and its mechanism. METHODS:Rabbits were selected to induce hypertrophic scar(HS)model,the HS model rats were randomly divided into model control group (normal saline),tranilast low-dose,medium-dose,high-dose groups (0.3,0.5,0.7 mg/kg),6 rabbits in each group,local intradermaly injected corresponding drugs. Scar thickness 1 h before injection and the first,third,fifth week after in-jection in each group were measured,pathological changes of scar(fifth week after injection)were observed,transforming growth factor β1 (TGF-β1),α-smooth muscle actin(α-SMA)mRNA and protein expression were detected. RESULTS:Compared with 1 h before injection,scar thickness of rabbits in other groups were decreased after injection except for model control group. In fifth week after injection,compared with model control group,scar thickness of rabbits in other groups were decreased,pathological changes were improved;TGF-β1,α-SMA mRNA and protein expression were decreased (P<0.05),showing positive correlation with tranilast dose. CONCLUSIONS:Tranilast can inhibit the formation of hypertrophic scar,and the mechanism may be related to inhibiting the TGF-β1,α-SMA mRNA and protein expression.

ObjectiveTo investigate the role of peroxisome proliferator-activated receptor gamma (PPARγ)/Caspase-8/Caspase-3 signaling pathway in the development of hyperlipidemia in rats.Methods 60 healthy male SD rats 〔4-week old,weight (110 ± 10) g〕 were randomly divided into control group,high-fat diet group,folic acid group,vitamin B12 group,folic acid and vitamin B12 group.After one week's feeding for adaptability,the groups of foloc acid,vitamine B12 and foloc acid + vitamineB12 were dealt with intraperitoneal injection of folic acid (0.5 mg/d),vitamin B12 (0.05mg/d),and folic acid (0.5 mg/d) plus vitamin B12 (0.05 mg/d),respectively,and fed with high fat diet simultaneously.Control group was dealt with intraperitoneal injection of normal saline (0.5 ml/d)and fed with normal diet.High-fat diet group was only fed with high fat diet.Reverse transcription polymerase chain reaction (RT-PCR) was used to measure the mRNA level of PPARy,Caspase-8 and Caspase-3 in aorta abdominalis dissected at 17 weekends.Results Folic acid alone or jointed with vitamin B12 could effectively increase the level of PPARγ,while decrease the mRNA levels of Caspase8 and Caspase-3 as compared with high-fat diet group (P＜0.05),and folic acid plus vitamin B12 was more effective than folic acid alone (P＜0.05).Conclusions Folic acid alone or joined with vitamin B12 can improve the mRNA levels of PPARγ,Caspase-8 and Caspase-3 in vascular wall to protect endothelial injury from hyperlipidemia.
