Abstract: Objective To investigate the antibacterial action and skin sensitization by percutaneous administration of lavender essential oil (LEO), providing a basis for its antibacterial application of percutaneous administration. Methods The disk diffusion method was used to evaluate the antibacterial effect of LEO on five types of bacteria, and to measure its minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC); The effect of LEO on guinea pig skin irritation was observed by topical application, and its allergic reaction and allergic rate were evaluated; the levels of IgA, IgG, and IgE in the supernatant of serum and spleen tissue sensitized with dimethylbenzene and smeared with LEO were determined by the enzyme-linked immunoassay (ELISA), and the antibacterial ability, skin sensitization, and inflammation of LEO were comprehensively evaluated. Results The antibacterial circle experiment showed that LEO had an inhibitory effect on Staphylococcus epidermidis, Escherichia coli, Candida albicans, Staphylococcus aureus, and Propionibacterium acnes; the antibacterial ability from strong to weak was Staphylococcus Epidermidis (8.25 mg/mL), Escherichia coli (15.00 mg/mL), Candida albicans (16.31 mg/mL), Staphylococcus aureus (18.00 mg/mL), Propionibacterium acnes (20.78 mg/mL). The percutaneous administration of LEO did not cause skin sensitization and inflammatory reaction in guinea pigs. Compared with the blank group, the effect of topical LEO application on the weight of the guinea pig's spleen is not statistically significant (P>0.05), and the effect on the levels of IgA, IgE, IgG in the serum and spleen tissue of guinea pigs is not statistically significant (P>0.05). Conclusions LEO has a certain antibacterial effect on five common pathogenic bacteria such as Staphylococcus epidermidis, Escherichia coli, Candida albicans, Staphylococcus aureus and Propionibacterium acnes, and is safe for percutaneous administration. The results provide some reference for the development of LEO related products and their application in the field of dermatology.

OBJECTIVE:
To investigate imaging and audiology features of temporal bone and analyze the classification and prevalence of inner ear abnormalities in children with sensorineural hearing loss.
METHOD:
Children who were diagnosed with sensorineural hearing loss were examined by high resolution CT and the inner ear fluid of MRI. And each chart was retrospectively reviewed to determine the imaging and audiology features.
RESULT:
There were 125 patients(232 ears) found with inner ear malformation in 590 children with SNHL. About 21.71% of the inner ear malformation occurred in severe and profound hearing loss ears, and 12.85% occurred in r moderate hearing loss ears. The inner ear malformation rate in normal hearing ears were 13.59%.
CONCLUSION
CT and MRI examinations of temporal bone are important diagnostic tools to indentify inner ear malformations. Inner ear malformations are almost bilateral and hearing loss are profoud. Cochleo-vestibular malformations and large vestibular aqueduct are the 2 most frequent deformities. Among the children with SNHL, deformity rate in the severe and profound hearing loss ears is higher than that in moderate hearing loss ear. Inner ear malformations can exist in people with normal hearing.

Objective To investigate the role of RhoA /Rho-kinase pathway in rat models of left heart disease-as-sociated pulmonary hypertension ( PH-LHD) .Methods Twenty male SD rats (3-4 week-old, 90-100 g) were randomly divided into two groups (10 rats in each group):the group C ( control group) with sham operation, and group H ( pulmo-nary arterial hypertension) .The rat model of left heart disease-associated pulmonary hypertension was established by supra-coronary aortic banding in the group H, and the sham surgery was applied for the rats in the group C ( The titanium clip was fixed at the mediastinal tissue adjacent to the artery rather than the ascending aorta).On day 60 after the operation, the cardiac functions, including right ventricular systolic pressure and pulmonary artery pressure were evaluated.After that, all rats were sacrificed and treated with cardiopulmonary lavage in vivo until the lung became white.Then the left lung tissues were fixed in 4%paraformaldehyde for pathological observation while the right lung tissues were frozen for mRNA detec-tion.Results Compared with the group C, both ventricular systolic pressure and pulmonary artery pressure in the group H were increased significantly (P<0.01).Pathological data demonstrated that the pulmonary artery walls in H group were much thicker than that in the group C.Moreover, vascular wall hypertrophy index in the group H was increased greatly compared with that in the group C (P<0.01).QPCR data showed that mRNA levels of Rho kinase, RhoA and ET-A R in the group H were up-regulated compared with the group C ( P<0.01) .Conclusions Rat model of left heart disease-asso-ciated pulmonary arterial hypertension can be successfully established by supracoronary aortic banding.Rho-kinase-media-ted pathway may contribute to the pathogenesis and progress of left heart disease-associated pulmonary arterial hypertension.
