Objective:To evaluate the clinical efficacy between preparation porcelain veneer(PPV)and no-preparation porcelain veneer(NPPV).Methods:44 patients with 97 PPVs and 23 patients with 57 NPPVs were followed up for 3 years.Mental tension, postoperative dentin sensitivity and satisfaction of the patients,survival rate of the veneers,sulcus bleeding index(SBI)of preopera-tive and postoperative 3 years were evaluated.A comparative analysis was taken to examine the clinical indicators of 2 groups accord-ing to the modified CDA /Ryge criteria.Results:Survival rates of PPVs and NPPVs were 96.91 % and 96.49%(P >0.05),satisfac-tion rates of the 2 group patients were 95.45% and 95.65%(P >0.05),respectively.Mental tension and the postoperative dentin sensitivity of patients in PPV group was higher than those in NPPV group.Preoperative and postoperative SBI were not statistically dif-ferent between the 2 groups(P >0.05).Marginal adaptation in PPV group was better than that in NPPV group.Color matching, Porcelain surface and Marginal stain were not statistically different between 2 groups.Conclusion:Preparation porcelain veneers and no-preparation porcelain veneers both are effective in clinical application.

Objective To study the imaging of inner ear malformations in children with congenital sensorineural hearing loss(SNHL).Methods CT and MRI examinations were performed on children with SNHL diagnosed by audiological test.One hundred and eighty-eight patients with complete imaging information were obtained.The imaging of inner ear malformations was analyzed according to Sennaroglu's classification. Results Thirty-five patients(54 ears) were found with inner ear malformations by CT and MRI,3 of whom(5 ears) were accompanied by outer and middle ear malformations.Among the 35 patients,2(4 ears) were found to be common cavity deformity,1(1 ear) cochlear hypoplasia,13(26 ears) incomplete partition II(Mondini deformity),4(7 ears) vestibule dilation,13(19 ears) semicircular canal deformity and 19(34 ears) large vestibular aqueduct.Internal auditory canal was found narrow in 7 patients(10 ears) and wide in 1(2 ears) with classic Mondini deformity. Conclusion CT and MRI examinations are of great importance to the diagnosis and treatment of inner ear malformations in children with congenital SNHL,especially for the candidates of cochlear implantation.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

Objective To compare the clinical efficacy and safety of isotretinoin erythromycin gel, a gel containing isotretinoin (0.05%) and erythromycin (2%), versus adapalene gel in the treatment of mild to moderate acne vulgaris. Methods A multicenter, randomized, open, parallel-controlled clinical study was conducted. A total of 192 patients with mild to moderate (Grade Ⅰ -Ⅲ ) acne vulgaris were enrolled in this study according to the grading criteria for acne severity in guidelines for the treatment of acne in China. Efficacy analysis was carried out in 169 patients and safety analysis in 190 patients. The patients were classified into trial group (n = 86) and control group (n = 83 ) to be treated with isotretinoin erythromycin gel or adapalene gel once a night for 6 weeks. Patients were evaluated at the baseline, on week 2, 4 and 6 during the treatment for the count of comedones (both open and closed), inflammatory papules and pustules, severity of acne and local or general adverse effects. Results After the start of treatment, the response rate gradually increased and severity of acne decreased in both groups. On week 6, the total response rate was 51.16% in the trial group and 40.96% in the control group (P ＞ 0.05), while a greater reduction in the count of pustules and inflammatory lesions was observed on week 4 and 6 in the trial group with a lower severity grade of acne compared with the control group (P ＜ 0.05 or 0.01 ). Adverse reactions were similar in both groups and manifested as tolerable local irritation. Conclusions The efficacy of isotretinoin erythromycin gel is similar to that of adapalene gel in the treatment of mild to moderate acne vulgaris, however, isotretinoin erythromycin gel seems superior to adapalene gel in reducing inflammatory lesions and rapidly improving severity of acne vulgaris.
