It is a challenging and important project to prolong the in vivo half life of protein and peptide drugs by physicochemical methods without new molecular entities generation. Protein crystallization provides a new strategy for improving the stability and in vivo delivery of these drugs. We show here that recombinant human interferon-alpha (rhIFN) can form spherical crystals. The physical and chemical features of the crystals were characterized, and drug dissolution was determined in vitro. The pharmacokinetics of crystallized interferon after sc injection in rabbit at 1.5 x 10(7) U x kg(-1) was compared to that of soluble form. The crystals were characterized as mono-dispersed spheres, with yield of > 80%, mean diameter size of about 16 microm and crystallinity of 23.2%. The in vitro dissolution behavior of crystallized rhIFN was featured as low initial burst release (21% within the first 2 h) and prolonged cumulative dissolution time up to 72 h without biological potency lost. After sc administration of soluble and crystallized interferon in rabbits, the peak time (T(max)) and half life (t1/2) were prolonged from (1.80 +/- 0.45) h and (1.35 +/- 0.35) h to (13.20 +/- 2.68) h and (10.68 +/- 1.97) h, respectively. The corresponding peak concentration decreased from (1 411.10 +/- 575.28) U x mL(-1) to (721.37 +/- 206.55) U x mL(-1). PK/PD analysis indicated that (96.87 +/- 20.30) % of relative bioavailability was obtained. The research results of this work will provide important academic value and application prospect for improving clinical therapeutic effect and development of biomacromolecules delivery system for protein and peptide drugs.

Objective To evaluate multichannel functional electrical stimulation (FES) on motor and balance function of lower limbs in adolescent with cerebral palsy. Methods From January, 2014 to June, 2015, 20 adolescents with cerebral palsy were randomly divided into FES group (n=10) and control group (n=10). Both groups received routine exercise therapy. FES group received active and passive FES treadmill based on normal walking pattern. The Fugl-Meyer Assessment (FMA) was used to evaluate the motor function of lower limbs;the Berg Balance Scale (BBS) was used to assess the balance function, and the Gross Motor Function Measure (GMFM) was used to test the gross motor function. Results The scores of FMA, BBS and GMFM significantly improved 30 days after treatment (F>223.749, P<0.001), and the scores were higher in the FES group than in the control group (t>2.706, P<0.05). Conclusion FES treatment can improve the motor and the balance function of lower limbs in adolescents with cerebral palsy.

Objective To explore tolerance-related factors of enteral nutrition(EN) by nasogastric (NG) tube in ICU patients, and to provide several nursing strategies for improving the patients' tolerance. Methods 83 patients using EN with NG tube in ICU were collected.Tolerance-related factors of EN were analyzed by multivariate Logistic regression analysis. Results Among the 83 patients, 36 patients (43.3%) could tolerate very well, 47 patients (56.6%) couldn't tolerate.After treatment 27 patients' tolerance was fair, the other was poor.Multivariate Logistic regression analysis showed that age, APACHE-Ⅱ score, the time of beginning EN, albumin level, drug administration by NG tube or not were the major factors affecting tolerance of NG tube feeding. Conclusions Patients' feeding with NG tube was well-tolerated in ICU.Besides the factors from patients as the severity of disease status and level of serum albumin,the time of beginning EN, drug administration by NG tube were significantly correlated with tolerance.

Objective This study was conducted to investigate the clinical outcomes and safety of percutaneous coronary intervention (PCI) to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction. Methods Twenty-seven patients with severe left ventricular systolic dysfunction (ejection fraction≤35%) undergoing PCI were included. All the patients received PCI only to the single-opened vessel lesion under the conditions of: (1) There were limitations to open chronic total occlusion (CTO);(2) Single-opened vessel lesion was not calcified and tortuous. Clinical outcomes, including success rate of PCI, changes of symptoms in-hospital, brain natriuretic peptide (BNP) and left ventricular ejection fraction (LVEF) pre-and one week post-PCI, the major adverse cardiac events (MACE, including death, myocardial infarction and target vessel revascularization) at 30-days after discharged were observed. Results The success rate of PCI was obtained in all 27 patients(100%), and all the patients received drug eluting stent implantation. The symptoms improvement occurred in all patients and the NYHA class improved from grade Ⅳto grade Ⅲin 22 patients(81.5%) in-hospital. Significant differences were noted in the mean BNP and LVEF between pre-PCI and one week post-PCI, BNP[(2699.6±1104.7) pg/ml vs. (737.0 ± 261.7) pg/ml, P<0.05],LVEF[(26.9±5.7)%vs. (36.0±3.41)%, P<0.05)]. No MACE happened in-hospital and at 30-days follow up. Conclusions PCI only to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction under the condition of limitations to open CTO is safe and can significantly improve clinical outcomes in-hospital and at 30-days follow up, but it must be emphasized that single-opened vessel lesion not with obvious calcification and tortuosity.

Objective To explore the role of ERK1/2 in the central pathogenesis of migraine.Methods Healthy adult male SD rats were randomly divided into five groups:normal group (group C),sham operation group(group C),migraine model group(group M),DMSO group (group D)and PD-98059group (PD group),with 12 rats in each group.The extracellular discharge frequency in the spinal trigeminal nucleus was recorded and ERK1/2 phosphorylation was tested.Results (1) The percentage of extracellular discharge frequency change:Two hours after treatment,the percentage of discharge frequency change was (325.9±47.32)％.The percentage of extracellula discharge frequency change in group M (325.9±47.3)％ was higher than that in group N (100.0± 0.0) ％ and group C(107.3± 16.4)％.There was no significant difference in the percentage of discharge frequency change between group D(319.3±42.5) ％ and group M (325.9±47.3) ％.The percentage of discharge frequency change in group PD(218.5±31.7)％ was lower than that in group M(325.9±47.3)％ and group D(319.3± 42.5)％.(2) ERK1/2 phosphorylation:the ERK1/2 phosphorylation in group M and group D was higher than that in group N and group C.There was no significant difference in ERK1/2 phosphorylation between group D and group M.The ERK1/2 phosphorylation in group PD was lower than the other four groups.Conclusion During the process of central sensitization to migraine,neuronal excitability and ERK1/2 phosphorylation were increased.ERK1/2 inhibitor (PD98059) reduced ERK1/2 phosphorylation and neuronal excitability.These indicated that ERK1/2 may play a role in central sensitization of migraine in rats.

Objective: To explore the impact of ticagrelor on myocardial microcirculation in patients of non-ST elevation myocardial infarction (NSTEMI) after percutaneous coronary intervention (PCI). Methods: A total of 80 NSTEMI patients treated in our hospital from 2015-03 to 2015-12 were enrolled. All patients received coronary angiography (CAG) and PCI, they were randomly divided into 2 groups: ticagrelor (TA) group and clopidogrel (CA) group, n=40 in each group. The baseline condition, PCI related parameters, plasma levels of SOD, MDA at pre- and 24h, 72h post-PCI were compared, the incidence of major adverse cardiac events (MACE) within 30 days after PCI was also compared between 2 groups. Results: The baseline condition, proportion of infarction-related vessels, average length and diameter of implanted stents were similar between 2 groups, all P>0.05. Compared with CA group, TA group had the less post-operative CTFC in LAD and RCA, P<0.05; while CTFC in LCX was similar between 2 groups, P>0.05. The ratios of acute pre-operative, post-operative TIMI grade 3 and slow flow incidence were similar between 2 groups, P>0.05. The peak values of CK-MB and cTnI in TA group were lower than CA group, P<0.05. Compared with baseline condition, MDA levels at 24h and 72h post-operation were increased in both groups, all P<0.001; compared with CA group, TA group had the lower MDA level at 24h post-operation, P=0.023, MAD was further reduced at 72h post-operation in TA group, P=0.043. Compared with baseline condition, SOD levels at 24h and 72h post-operation were decreased in both groups, all P<0.001; compared with CA group, TA group had the higher SOD level at 24h post-operation, P=0.013, SOD was elevated at 72h post-operation in both groups, the elevation was more obvious in TA group, P=0.049. The incidence of MACE was similar between 2 groups within 30 days of PCI,. Conclusion: Ticagrelor could improve myocardial microcirculation in NSTEMI patients after PCI; it was safe and without obvious adverse effects.

Objective To study the effect the edaravone on the expressions of ICAM-1,TNF-α after focal cerebral ischemia reperfusion in male rats.Methods 45 male SD rats were selected and randomly assigned into 3 groups:sham operation group(SO),ischemia reperfusion group(I/R),and edaravone treatment group(ED),each group had 15 rats.The expression of ICAM-1,TNF-α were checked by immunohistochemistry.All data in the groups were analyzed with t test.Results The expression of ICAM-1 and TNF-α in the I/R group and ED group were higher than the SO group(t=21.919,27.758,26.576,17.395,32.821,43.021,14.195,31.828,21.201,10.195,25.768,17.900,all P＜0.05)at reperfusion 3 hours,6 hours,and 12 hours.The expression of ICAM-1 and TNF-α in the I/R group were higher than the ED group(t=9.623,13.845,7.201,11.313,all P＜0.05)at reperfusion 3 hours and 6 hours.Conclusion Edaravone may exert the neuroprotective effect against the cerebral ischemia in rats by decreasing the expression of ICAM-1 and inhibiting the activation of TNF-α.This process could inhibit free radical generation.
