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 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.

Objective To investigate Glypican-3 gene expression and mutation in hepatocellular carcinoma (HCC).Methods Glypican-3 gene expression and mutation in tumor,para-c.ancer and normal tissue of 48 HCCs were detected by RT-PCR and single-strand conformation polymorphism(SSCP),respectively.Results There was no Glypican-3 mRNA expression in para-cancer and normal tissue.Expression rate of Glypican-3 mRNA was 77.1% in tumor tissue,which was correlated with clinical staging and cell differentiation(P

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 clinical characteristics,treatment and prognosis of primary pe-noscrotal extra-mammary Paget’s disease (PSPD).Methods:The clinical and pathological data of 22 cases of primary PSPD were retrospectively reviewed.Survival rate of the overall patients,the invasive patients,and the patients with positive surgical margin or negative surgical margin were analyzed with Ka-plan-Meier survival curve method.Results:Among all the patients with primary PSPD,the median age of onset was 64.5 (39 -84)years,the median time of disease duration was 40 (2 -300)months,and the median long diameter of lesion was 4.75 (1 -10)cm.In the study,12 patients (54.5%)were in pathological stage A1,6 patients (27.3%)were in pathological stage A2,and 4 patients (18.2%) were in pathological stage B.Scrotum and penile of most patients (n =12,54.5%)were involved,5 patients (22.7%)were scrotum only,and 5 patients (22.7%)were penile only.Erythema (n =18, 81.8%),itchiness (n =16,72.7%),ulcerate (n =12,54.5%),exudation (n =11,50.0%),and pain (n =4,18.2%)were the major manifestations.All the patients with primary PSPD were treated with wide surgical excision.The rate of invasive patients was 77.3% (n =17).Of them,6 patients had positive surgical margin.The surgical margins of non-invasive patients were all negative.Twelve patients exhibited local recurrence or/and metastases,and the status of surgical margins (P =0.015)and the depth of invasion (P =0.010)were important risk factors.Inguinal lymph nodes were generally in-volved.The difference of the delay of diagnosis between metastasis and non-metastasis was significant (P =0.040).The 5-year survival rates of the overall and invasive patients were 33.7% and 27.9%, respectively.The patients with positive surgical margin had poor prognosis.Conclusion:Primary PSPD, with the characteristics of long duration,high invasive tendency and high incidence of local recurrence or metastases,generally occurs in the elderly.Surgery should be performed at first.The delay of diagnosis, positive surgical margins and the involvement of inguinal lymph node are important risk factors.Biopsy, frozen section and inguinal lymph node biopsy (ILNB)can standardize diagnosis and treatment.

Objective To explore the change of glyoxalase I in type 2 diabetic ocular muscles palsy (DOMP) and its associations with advanced oxidation protein products (AOPP) and oxidative stress. Methods 58 DOMP patients, 50 T2DM and 30 normal controls were enrolled in this study. Levels of blood lipids, fasting blood glucose, hemoglobin A1c, insulin, serum glyoxalase I, AOPP, malondialdehyde (MDA), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) were measured. Homeostasis model assessment was performed to evaluate the status of insulin resistance (IR). Results Levels of high-density lipoprotein cholesterol, SOD and T-AOC were positively correlated with glyoxalase I and inversely associated to AOPP. Levels of triglycerides , low-density lipoprotein cholesterol , fasting blood glucose , hemoglobin A1c , IR and MDA were negatively correlated with glyoxalase I and positively related to AOPP. AOPP had an inverse association with glyoxalase I (r = -0.823, P < 0.001). Multivariate regression analysis showed that serum levels of glyoxalase I (Sβ = 0.554) and AOPP (Sβ= -0.469) were influencing factors of groups. Conclusion Serum glyoxalase I levels were significantly decreased in DOMP and correlated with AOPP and levels of oxidative stress , which suggest that glyoxalase I could play crucial roles on the development of DOMP.

Objective To investigate the effects of advanced oxidation protein products (AOPP) in type 2 diabetic ocular muscles palsy (DOMP). Methods 58 DOMP patients and 50 type 2 diabetes patients were included in the research. Hemoglobin A1c (HbA1c), blood glucose (FPG), fasting insulin (FINS) and triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) were measured and recorded. Homeostasis model assessment was performed to evaluate the status of insulin resistance (HOMA-IR), basal insulin secretion (HOMA-β) and the insulin sensitivity index (ISI). Serum AOPP was measured by enzyme linked immunosorbent assay. Unconditional logistic regression model was used to evaluate the influencing factors of DOMP. Results The DOMP group showed higher levels of plasma AOPP, TG, LDL, FPG, FINS, HbA1c and HOMA-IR, but lower levels of HDL, HOMA-β and ISI than those of the T2DM group. Unconditional logistic regression analysis revealed that AOPP was an independent risk factors for DOMP (OR =3.01, P = 0.002). Conclusion AOPP may be involved in the pathogenesis of DOMP. AOPP could be a useful indicator for monitoring the development of DOMP and for evaluating its severity.

OBJECTIVETo explore the strategy of pediatric intractable epilepsy surgery.

METHODSThe clinical data of 96 pediatric cases with intractable epilepsy and epilepsy syndromes underwent surgical treatment from April 2004 to April 2006 were retrospectively analyzed.

RESULTSThe surgical treatments were performed based on the results of comprehensive data from neurological, neurosurgical and pediatric departments. Among of them, 78 cases were performed with curative procedure, 17 cases with palliative procedure and 1 case with stereotactic damage procedure. The surgical effect was judged with Engel's standard, 58 cases had no seizure during 14 to 26 months follow-up, 26 cases had significantly improved in seizure control and the total efficiency was 87.5%. 81 cases had improvements in neuropsychological tests. 22 cases had postoperative complications such as neuro-dysfunctions and 15 cases were gradually recovered after the period of follow-up ended, 1 case died of CSF over drainage after operation 3 months.

CONCLUSIONSPediatric patients with symptomatic epilepsy and epilepsy syndromes are suitable to surgical treatment, the results are satisfactory in seizure control and neuropsychological function tests.
