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 evaluate the imaging features of patients with vascular cognitive impairment (VCI) induced by Subcortical Ischemic Vascular Disease (SIVD), through magnetic resonance diffusion tensor imaging ( DTI ) and proton spectroscopy ( MRS ) technology. Methods A total of 52 patients with SIVD were enrolled. After analysis of scale score, 32 patients with cognitive impairment were assigned to VCI group and 20 patients with no cognitive impairment were assigned to control group. Both group received DTI and MRS examination. The mean values of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) of the bilateral temporal, frontal, parietal and occipital white matter regions as well as in the bilateral centrum semiovale were calculated. The peak value of MRS of N-acetyl aspartate (NAA) , choline ( Cho), creatine (Cr) and phaseomannite ( mI ) were calculated. Results Compared with control group, FA decreased in the region of temporal, frontal, parietal as well as in the centrum semiovale , and ADC increased in VC[group ( P ＜ 0.05 ) . In the frontal regions and centrum semiovale,the VCI patients had a significant FA decrease. The ADC value increased obviously in the temperal lobe.Spectrum analysis results showed, NAA/Cr was lower than control group in VCI group in the frontal lobe (1.43 ±0.08 vs 1.53 ± 0. 92), while mI/Cr was higher than control group in the temporal lobe(0. 51 ±0. 06 vs 0. 46 ± 0. 07 ) ( P ＜ 0. 05 ). Conclusion FA in the temporal and centrum semiovale regions of VCI group and NAA in the temporal white matter regions decreased obviously. DTI and MRS could provide a reference value for early diagnosis and assessment of VCI.

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 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 observe the postoperative analgesic effects of ultrasound-guided transversus abdominis plane block after cesarean section. Methods Forty patients having underwent cesarean section under intraspinal anesthesia were selected, and they were divided into experiment group and control group by random digits table method with 20 cases each. All the patients were given ultrasound-guided transversus abdominis plane blocks when surgery finished. The patients in experiment group were injected 0.25%ropivacaine 20 ml, and the patients in control group were injected 0.9% sodium chloride 20 ml. All the patients received patient controlled intravenous analgesia (PCIA) pump after surgery. The movement and resting visual analog score (VAS), incision VAS at 4, 8, 12 and 24 h after surgery, and the compression time of analgesis pump were compared between 2 groups. The correlated adverse reaction of transversus abdominis plane block were recorded. Results The movement VAS at 4 and 8 h after surgery in experiment group were (4.1±1.7) and (5.3±1.8)scores, and in control group were (6.3±2.0) and (7.0±1.2) scores, and there were statistical differences (P<0.05). The incision VAS at 4 and 8 h after surgery in experiment group were (0.9±0.4) and (1.2±0.8) scores, and in control group were (3.6±2.1) and (6.8±2.4) scores, and there were statistical differences (P<0.05). The compression time of analgesis pump in experiment group was significantly lower than that in control group: (2.8± 1.4) times vs. (4.0±1.9) times, and there was statistical difference (P<0.05). The using dose of tramadol in experiment group was significantly lower than that in control group:(214±12) mg vs. (224±15) mg, and there was statistical difference (P<0.05). All the patients did not appear the correlated adverse reaction of transversus abdominis plane block. Conclusions Ultrasound-guided transversus abdominis plane block is accurate and easy. It provides effectual post-cesarean section analgesia with lower adverse reaction, which is a better choice of multimodal analgesia for cesarean section.
