Objective To study the value of insulin like growth factor binding protein-1 of cervicovaginal secretion in the delayed pregnancy termination. Methds Phosphorylated isoforms of IGFBP-1 in cervicovaginal secretion of 202 delayed pregnant women were measured by immmmunochromatography. Results In the IGFBP-1 positive group. The rate of successful pregnant termination in three days was 91 2%, while in IGFBP-1 negative group, the rate of that was 41 8%..There was statistically significant diference in the rate of successful pregnant termination between the two groups(P

Objective To analyze the allergens detection in asthmatic infants and young children. Methods The specific IgE test and allergens screening test were conducted in 243 infants and young children with whooping diseases including asthmatic bronchitis, asthmatic pneumonia and asthma by skin prick test and Pharmacia UniCAP test. Results 1. Food allergen was the allergen detection most frequently in infants(P = 0.03). The proportion of aeroallergens increased significantly with age (positive rate:67. 2%). Milk and egg white was the main food allergen detection in infants and young children,and the main aeroallergen detection was house dust mite. 2. The allergen - specific IgE test using UniCAP test system was more accurate than skin prick test. Conclusions The infants are more susceptible to food hypersensitivity; the increasing opportunity of aeroallergen exposure may lead to a higher prevalence of aeroallergens in young children. UniCAP system is more accurate than other methods.

AIM: To analyze the associated factors of poor vision after phacoemulsification operation.
METHODS:Clinical data of cases with poor vision after cataract phacoemulsification combined with IOL implantation from 341 patients(418 eyes) during Jan. 2015 to Jan. 2016 in our hospital were collected and logistic correlation analyzed.
RESULTS: The incidences of postoperative low vision were 10. 3% for one month after operation. Forty-three eyes were reported low vision, and 41 of 43 the patients with postoperative low vision had fundus oculi disease before operation, which included 20 eyes ( 48. 8%) with age-related macular degeneration, 16 eyes(39. 0%) with diabetic retinopathy, 3 eyes ( 7. 3%) with glaucomatous optic neuropathy, 1 eye(2. 4%) with pathologic myopia of retinopathy and 1 eye ( 2. 4%) with branch retinal vein occlusion.
CONCLUSION: The associated factors of poor vision after phacoemulsification operation are preoperative eye diseases and the nuclear hardness, and preoperative eye diseases may be the main causes of postoperative low vision. Comprehensive examination should be attached importance to, and be careful in the operation to decrease the harm for visual performance.

Objective To understand the functional status and radiation protection requirements of helical tomotherapy (TOMO) unit when it is applied in clinic treatment so as to promote the construction of TOMO quality control system.Methods A helical tomotherapy unit with a type of tomotherapy Hi-Art was employed as the radiotherapy unit.A series of tests and analyses on dosimetric and radiation safety performance parameters of the TOMO unit were conducted with the use of a A1SL ionization chamber,a set of solid water equivalent phantoms and other test equipments.The performance parameters were compared with that of a conventional 6 MV accelerator with a type of ARTISTE.Results The deviations of static and dynamic output dose were-1.51％ and 1.18％,respectively.The values of PDD10/PDD1.5 and PDD20/PDD1.5 were 0.608 and 0.318 within the range of X-ray quality parameters calibration.Under the different field conditions of 40 cm × 5 cm,40 cm × 2.5 cm and 40 cm × 1 cm,the stability of transverse/longitudinal dose distribution curve was no more than 1.20％ and the offset distance of Jaw width was smaller than 0.5 mm.Radiation leakage ratio of the treatment rotating center from the muhileaf collimator (MLC) was 0.20％.No matter the average or the maximum value of the leakage radiation from couch plane was less than 0.02％.Conclusions The performances and testing requirements of TOMO unit are different from a conventional electron linear accelerator,the quality control index of TOMO unit should be set seperately and tested strictly in terms of the specific requirements of the unit by complying with the QC programme.The reliable quality control system should be established and effectively implemented to serve the radiotherapy quality and radiation safety effectively in the tomotherapy.

[Objective] To explore the feasibility and advantages of blood microdialysis technique for the pharmacokinetic study of sinomenine. [Methods] In this study, rats served as the experimental subjects and sinomenine was administered to the rats by intravenous injection. With microdialysis technique for blood sampling, the blood concentration of sinomenine was determined by high performance liquid chromatography (HPLC) and the associated pharmacokinetic parameters were analyzed by 3p97 program. [Results] The pharmacokinetics process of sinomenine in rats presented as the two-compartment model. The half-life of distribution phase was 10.98min and that of elimination phase was 44.71 min. [Conclusion] It is feasible to study pharmacokinetic parameters of sinomenine by using blood microdialysis technique. In comparison with the traditional technique, blood microdialysis technique is superior to the examination of drug blood concentration .

SUMOylation is a post - translational modification consisting of covalent conjugation of ubiquitin - like proteins called small ubiquitin related modifier ( SUMO ) . SUMO modification has been shown to significantly alter protein activity, which can modulate protein stability, affect protein-protein interactions, and modify protein localization and trafficking. This process adds another layer of control in eukaryote gene expression, and it regulates both transcriptional activation and repression. This article reviews the current situation and future development of SUMOylation in ophthalmology.

Objective To investigate the protective effects and molecular mechanism of peroxisome proliferate-activated receptor α(PPARα) activation on acute myocardial damage induced by isoproterenol (Iso) in rats. Methods Thirty male Wistar rats, weighting 160～180 g, were randomly divided into control group, Iso group, fenafibrate(FF) group(each n=10) according to physique quantity. Acute myocardial injury caused by Iso abdomen cavity injection induced ischemia was established and the protective effects of peroxisome proliferate-activated receptor α activation were accessed by the level of ereatine kinase(CK), lactic dehydrogenase(LDH) in serum as well as the activities of myoperoxidase(MPO) in myocardium, and the protein expressions of PPABα in myocardium by Western blot. Results The level of serum CK in control group, lso group and FF group, was (62.41±9.47),(101.71±11.05),(75.64±11.73)kU/L, respectively(F= 34.34, P<0.01). Whereas the level of serum CK in Iso group and FF group was higher than that in control group(P<0.01 or<0.05), the level of serum CK in FF group was lower than that in Iso group(P<0.01). The levels of LDH in these three groups were (5912.20±204.44), (6365.78±137.10), (6089.76±169.60) U/L, respectively(F= 17.54, P<0.01). Compared with the control group, the levels of LDH in Iso and Fir groups were significantly increased(P<0.01 or<0.05). But the level of LDH in FIr group was decreased compared with that in Iso group(P<0.01). The activities of myocardial MPO in these three groups were (1.95±0.10),(3.89±0.17),(2.49±0.19)U/g, espectively(F=391.68,P< 0.01). The activities of myocardial MPO in Iso and FF groups were higher than that in the control group (all P< 0.01), while the activities of myocardial MPO in FIr group were lower than that in lso group(P<0.01). The protein expressions of PPARα in myocardium of these three groups were 251.57±10.95,191.97±10.74,215.08±9.61, respectively(F=82.69, P<0.01). Conclusion PPARα activation by its actor FF can exert protective effects on the acute myocardial ischemia injury induced by lso in rats through inhibiting the release of inflammatory cell factors.
