Objective To make a survey on common cosmetic allergens, and to provide epidemiological data and clinical evidence for cosmetic allergy. Methods Patch test was performed by using 49cosmetic allergens from a European cosmetic series and 5 Chinese standard screening allergens on 89patients with suspected cosmetic allergic contact dermatitis. Test results were determined according to the International Contact Dermatitis Research Group (ICDRG) recommendation. Results Of the 89 patients, 61(68.5%) showed positive reactions to one or more cosmetic allergens. The most common allergens were fragrances (33.7%), followed by preservatives (30.3%), para-phenylenediamine (25.8%) and amerchol L 101(10.1%). Conclusion Fragrances, preservatives, para-phenylenediamine and amerchol L 101 are dominant causative allergens in patients with cosmetic allergic contact dermatitis.

Allergic rhinitis and rhinosinusitis often complicate with asthma,and their relationship has long been investigated.From the view of epidemiology,all of these three diseases have higher prevalence,complicate with each other,are risk factors and prognostic factors for each other.Besides,they share common in anatomy and pathophysiology.In this paper,the interrelationship among allergic rhinitis,rhinosinusitis and asthma in pathogenesis is discussed.

AIM: To compare the peripapillary retinal nerve fiber layer ( RNFL ) thickness and peripapillary topographic map's parameters between amblyopic eyes and non -amblyopic eyes in adolescent with anisometropic amblyopia by optical coherence tomography(OCT).
METHODS: Thirty - four juveniles with anisometropic amblyopia were selected. Peripapillary RNFL thickness and peripapillary topographic map were measured by frequency domain OCT with both eyes in all participants, and the differences between amblyopic eyes and non -amblyopic eyes were compared.
RESULTS: There was no significant difference in average thickness of peripapillary RNFL and in any other region of peripapillary RNFL. The disc area in amblyopic eyes was bigger than that in non - amblyopic eyes ( t =2. 8054,P= 0. 0263). The disc area in amblyopic eyes were significantly related to the thickness of nasal RNFL and the rim area(r= 0. 7592,0. 7501;P= 0. 0289,0. 0321).
CONCLUSION: There existed some difference in peripapillary structure between amblyopic eyes and non-amblyopic eyes in adolescent with anisometropic amblyopia.

Genuine medicinal materials with special characteristics of Traditional Chinese Medicine (TCM), is recognized as high quality medicine. Both ancient records and modern research considered that the origin is an important reason for the formation of genuine medicinal materials. However, blindly transplanting of genuine medicinal materials has led to the quality decline and counterfeit medicines appeared in production or sale progress, which may increase the risk of accidents in TCM. Frequent accidents emerged in Chinese herbal affects its export. What's more, it is a great threat to the medication safety in TCM clinical. There is an urgent need to implement traceability systems of TCM, which could provide convenient information record and traceability of TCM circulation. This paper reviews a variety of technical methods for genuine medicinal materials traceability, and proposed the establishment of genuine medicinal materials traceability system based on two-dimensional code and network database.

ObjectiveTo investigate the influences of routine-dose loratadine on the positive patch test reaction to nickel sulfate.MethodsA double-blind,controlled and randomized study was carried out.A total of 121 patients with a positive patch test reaction to nickel sulfate were divided into two groups to receive loratadine 10 mg (experimental group,n =61 ) or placebo (control group,n =60) once daily for 14 days.The patch testing of nickel sulfate was performed on day 11,and clinical evaluation of the test was carried out on day 14 after the start of treatment.The intention to treat population was used for data analysis.ResultsNo changes were observed in the intensity of patch test reaction to nickel sulfate in 55 patients in the experimental group or 53 patients in the control group,and there was no significant difference between the two groups in the percentage of patients showing changes in the intensity of patch test reaction(9.8％ vs.11.7％,x2 =0.11,P ＞ 0.05).ConclusionThe routine-dose loratadine has no inhibitory effect on the intensity of skin patch test reaction to nickel sulfate.

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.

Objective To evaluate the functional changes of visual cortex (V1) in patients with primary open angle glaucoma (POAG) by fMRI retinotopic mapping technology. Methods Fifteen POAG patients and 15 healthy volunteers underwent stimulations with fMRI retinotopic mapping stimulus and contrast-reversing checkerboard patterns stimulus on a Siemens Trio 3.0 T MRI whole-body scanner for functional data collection. Comparisons of V1 fMRI responses between the glaucomatous eyes and the healthy eyes of the patients were carried out using paired samples t-test, while independent samples t-test was used to compare V1 fMRI responses and activations between the healthy eyes of patients and the age-, gender- and side- matched eyes of normal people. Differences of V1 cortical functions and visual functions were analyzed by linear correlation analysis when the glaucomatous and the healthy eyes were simulated individually. Results (1) V1 fMRI responses of the individually stimulated glaucomatous eyes[(1.24±0.72)%]were weaker than those of the healthy eyes[(2.18±0.93)%](t=4.757,P<0.01). Comparisons of V1 fMRI responses between the glaucomatous eyes and matched eyes of normal people, as well as between the healthy eyes of patients and the matched eyes of normal people, were performed respectively: the responses in the glaucomatous eyes[(1.24±0.72)%]were weaker than those in the matched eyes of normal people[(2.01±0.65)%](t=-3.011,P<0.01). There was no statistical difference of the responses between the healthy eyes from patients[(2.18±0.93)%]and the matched eyes of normal people[(1.95±0.75)%](t=0.742,P＞0.05). (2) Differences of V1 cortical functions were negatively correlated with those of visual functions in the individually stimulated glaucomatous and healthy eyes (r=-0.887, P<0.01). (3) The activated area indexes of V1 cortexes in the healthy eyes from patients (0.72±0.12) were lower than those in the matched eyes of normal people (0.85±0.09) (t=-3.801, P<0.01). Conclusion Cortical function impairment was in accordance with visual function impairment in glaucoma. Located and quantified measurement with fMRI retinotopic mapping was a useful method for clinical follow-up and evaluation of functional alteration of glaucomatous visual cortex, and a potentially useful means of studying trans-synaptic degeneration of visual pathways of in vivo glaucoma.
