OBJECTIVE: To provide references for the improvement of drug recall system in China.METHODS: The problems existing in the drug recall system in China were analyzed through a comparison of the drug recall system between China and Australia.RESULTS & CONCLUSIONS: China should draw useful experiences from Australia to improve its drug recall system by perfecting the legal system and tracking measures,determining stratified drugs and the responsibilities of government etc.

Objective To evaluate the clinical application of enzyme-linked immunospot(ELISPOT) assay for detection of M.tuberculosis antigen specific T cells in the rapid diagnosis of active tuberculosis.Methods Using the rapid enzyme-linked immunospot assay for detection of T cells with secretion of IFN-? specific for M.tuberculosis antigens in blood samples from 112 patients with tuberculosis, 24 patients with hepatitis C, 30 healthy persons, and 65 with other respiratory diseases.Results 107 of 112 tuberculosis patients had detectable M. tuberculosis antigen-specific T cells, whereas 2 of 30 healthy subjects and 65 patients with non-tuberculosis illnesses responded. This assay has a sensitivity of 95.5%, specificity of 93.3%.Conclusions M.tuberculosis specific T cells could serve as accurate markers of M.tuberculosis infection in an area of high tuberculosis prevalence.ELISPOT is a rapid, sensitive and specific method for detecting M.tuberculosis specific T cells.It also gives objective evidence to the diagnosis of active tuberculosis.

Objective To explore the effect of preventing adhesion after the orbital blowout fracture on orbit tissue by amniotic membrane. Design Experimental study. Participants Twenty-six New Zealand rabbits. Methods Establishing rabbit orbital blowout fracture model, the right orbit of twenty rabbits was repaired by hydroxyapatite (HA) parceled of amniotic membrane, and left orbit was only repaired by HA, the orbits of the other six rabbits weren't repaired. Then we got the tissue around bone after one week and one month, and compared the difference of three groups. Main Outcome Measures Inflammatory response of tissue around bone was ana- lyzed by HE, picric acid Sirius Scarlet dying, TGF-?immunohistoehemical observation. Results One week after operation, HE and im- munohistochemistry showed that the difference was not significant in inflammatory response between experimental group and control group (P=0.351, P=0.413), and difference is significant between blank group and experimental group (P=0.012, P=0.041). One month after operation, HE and immunohistoehemistry showed that the difference was significant in inflammatory response between experimental group and control group(P=0.037, P=0.048), and there is no significant difference between experimental group and blank group(P=0.285, P=0.472). Conclusion It has an important role of anti-inflammatory and anti-adhesion in the chronic stage of inflammatory after orbital blowout fracture repaired by man-made plates of amniotie membrane.

The correct pairing of disulfide bonds maintains the correct folding mode and high-level structure formation of peptides and protein drugs, which is crucial for the quality control of products. In order to ensure that the disulfide bonds are correctly paired, disulfide bond analysis is an essential part of peptides and protein drug characterization. Mass spectrometry can be used to analyze disulfide bonds. However, insulin and its analogues have two pairs of disulfide bonds without restriction enzyme cutting site. Conventional collision-induced dissociation (CID) and high-energy induced cleavage (HCD) cannot accurately locate the complex disulfide bond. In our study, three methods were used to localize the complex disulfide, including enzyme digestion combined with key peptide fragment in source decay (ISD) fragmentation method, enzyme digestion combined with partial reduction alkylation method, intact protein source ISD and electron transfer dissociation (ETD) cleavage method, The applicability of insulin aspart, insulin lispro and insulin glargine were also investigated. This study provides a new way for the quality control of disulfide bonding mode of insulin and its analogues, and also provides a reference for the disulfide bond localization of peptides or proteins containing this complex disulfide bond.

Objective To explore the effects of wearing ankle-foot orthoses (AFOs) on motor function in children with spastic cerebral palsy (SCP). Methods Fifty-two children with SCP were randomly divided into a wearing-for-training group (n = 16, group 1 ), a day-wearing group (n = 19, group 2) and a day-night-wearing group (n = 17, group 3). In addition to the conventional rehabilitative treatment given to all participants, the children in group 1 wore AFOs during movement training, and children in group 2 wore AFOs in the daytime for 6-8 h per day, while AFOs were applied to the children in group 3 for 24 hours a day except for cleaning and during certain training routines. All the treatments were continued for 2 months. Clinical assessments included the range of passive ankle dorsi-and plantarflexion (APROM) , modified Ashworth scale (MAS) ratings, and the D and E dimensions of the Gross Motor Function Measure (GMFM). All were performed before and after treatment. Results Before treat-ment, no statistically significant differences were found among the three groups in terms of APROM, MAS, or GM-FM. There were significant subsequent improvements in groups 2 and 3 when compared with group 1 in terms of APROM, MAS and GMFM results. Group 2's improvements in APROM and MAS results were not significantly better than those of group 3, but their average GMFM score improvements were significantly better. Conclusion Wearing AFOs in the daytime 6-8 hours per day is more effective in reducing spasticity and improving functional performance in children with SCP.
