Objective To observe the effect of scalp acupuncture and rehabilitation training on the regulation of neuro-plasticity-associated protein MAP-2 in gerbils modelling cerebral ischemia and reperfusion.Methods Cerebral ischemia and reperfusion were modelled into thirty-six male gerbils.They were then randomly divided into a model group (A),a scalp acupuncture and rehabilitation training group (B) and a rehabilitation training group (C),each of 12 cases.The scalp acupuncture and rehabilitation training were administered daily to the gerbils in group B beginning 24 h after modeling,for 14 d.Any changes in Bederson scores were observed after one,7 and 14 days.On the 14th day the expression of MAP-2 around the infarct focus was detected using western blotting in all 3 groups.Results On the 7th day the average Bederson score in group B (1.81 ± 0.52) was not significantly different from that in group A (2.13 ± 0.49) or group C (2.00 ± 0.31) (P ＞ 0.05).At the end of the treatment,however,there were significant differences between the groups,with group B (0.47 ± 0.31) scoring significantly better than groups C (1.04 ± 0.63) and A (1.46 ± 0.72) (P ＜ 0.05).Group C was also significantly better than group A (P ＜0.05).The expression of MAP-2 as measured as integrated optical intensity (IOD) in group B (0.91 ±0.18) was significantly higher than that in group A (0.43 ± 0.21) and group C (0.67 ± 0.24) (P ＜ 0.05) ; so was group C compared to group A (P ＜0.05).Conclusion The scalp acupuncture combined with rehabilitation training can improve the recovery of motor function and enhance the expression of neuro-plasticity-associated protein MAP-2 in gerbils with after cerebral ischemia and reperfusion.

Peptide drugs exhibit an irreplaceable role in clinics due to their high specificity, efficiency and low toxicity. At present, more than 80 peptide drugs have been approved for marketing with global sales exceeding $50 billion in 2019. However, with large molecular weights, high hydrophilicity and instability in digestive tract, oral peptide drugs encounter substantial physiological barriers leading to low oral bioavailability. Therefore, peptide drugs are mostly administered by parenteral routes. Although parenteral delivery of peptide drugs achieves high bioavailability, this is associated with inconvenience and discomfort, even causing severe side effects compared with the oral route possessing a high degree of patient compliance. Therefore, numerous studies concentrate on novel strategies to improve the oral bioavailability of peptide drugs. Some delivery technologies such as Eligen™ and Axcess™ have been successfully applied to the oral dosage form of therapeutic peptides and have accelerated relevant oral formulations for Food and Drug Administration (FDA) approval and clinical treatment. In this review, we focus on the oral peptide delivery, mainly summarizing the progress of recent strategies used to overcome oral barriers and the commercialization applications of related patents, which could facilitate the research and development (R&D) of clinical applications of oral delivery techniques for peptide drugs.

Objective To explore the correlation between the two methods of pulmonary arterial thermodilution technique(ThDCO)and pulse indicator continuous cardiac output(PiCCO)in determining hemodynamic changes in patients undergoing orthotopic liver transplantation(OLT).Methods Eighteen patients with end-stage liver disease(ASAⅡ-IV)were performed OLT and monitored hemodynamic changes by PiCCO method and ThDCO method simultaneously.The hemodynamic parameters including mean arterial pressure(MAP),cardiac output(CO)and systemic vascular resistance(SVR)were measured at different time points before anesthesia induction,after tracheal intubation,after the beginning of operation,at anhepatic phase,at neohepatic phase,at the end of operation,and after operation.Results Good correlation was found between the two methods for the determination of CO and SVR(r=0.987,P0.05).Conclusion The hemodynamics change dramatically in patients undergoing OLT.There is good correlation between the two methods of PiCCO and ThDCO for perioperative hemodynamic monitoring in patients undergone OLT,and PiCCO detection can be used conveniently for real-time continuous monitoring.

OBJECTIVE: To investigate the expression of Myosin VI and Disabled-2 (Dab2) in the cochlea of mice at different ages. METHOD: Forty KM mice were divided into four groups according to age, named as postnatal 2 week (P2w), P5w, P9w, P16month. The localization of protein in the basilar membrane of mice cochlea was detected by immunofluorescence staining and laser scanning confocal microscope (LSCM). The mRNA expression level of protein in cochlear at different ages was evaluated by real-time fluorescent quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Statistical analysis was performed by the SPSS18.0 software. RESULT: Myosin VI and Disabled-2 protein mainly expressed at the apical cytoplasm of hair cells. As for the inner hair cell, Dab2 labeling was abundant especially at the cuticular plate and nearby. Comparing four immunofluorescence staining images of Myosin VI, we found the fluorescence intensity of P2w and P16m were weaker than that of P5w and P9w. After setting P9w as the control group, qRT-PCR revealed that the mRNA expression of MyosinVI and Dab2 in P2w was less than that in the control group (P < 0.01), while no significant difference was found between P5w and the control group, nor between P16m and the control group (P > 0.05). CONCLUSION Myosin VI and Dab2, two proteins which regulated the clathrin-mediated endocytosis, expressed at hair cells of mice cochlea. In the inner hair cell, this process of endocytosis may be more efficient at the cuticular plate and nearby. The expression level of protein may change in different ages, and this probably leads to a difference of CME, it also may cause a defect of inner hair cells function.

Alzheimer' s disease (AD) is the most common form of dementia in the elderly. AD is an invariably fatal neurodegenerative disorder with no effective treatment. Senescence-accelerated mouse prone 8 (SAMP8) is a model for studying age-related cognitive impairments and also is a good model to study brain aging and one of mouse model of AD. The technique of cDNA microarray can monitor the expression levels of thousands of genes simultaneously and can be used to study AD with the character of multi-mechanism, multi-targets and multi-pathway. In order to disclose the mechanism of AD and find the drug targets of AD, cDNA microarray containing 3136 cDNAs amplified from the suppression subtracted cDNA library of hippocampus of SAMP8 and SAMR1 was prepared with 16 blocks and 14 x 14 pins, the housekeeping gene beta-actin and G3PDH as inner conference. The background of this microarray was low and unanimous, and dots divided evenly. The conditions of hybridization and washing were optimized during the hybridization of probe and target molecule. After the data of hybridization analysis, the differential expressed cDNAs were sequenced and analyzed by the bioinformatics, and some of genes were quantified by the real time RT-PCR and the reliability of this cDNA microarray were validated. This cDNA microarray may be the good means to select the differential expressed genes and disclose the molecular mechanism of SAMP8's brain aging and AD.
