OBJECTIVE:To explore the clinical efficacy and safety of Yunkang granule combined with dydrogesterone in the treatment of early threatened abortion. METHODS:128 patients with early threatened abortion were randomly divided into single drug group and combined medication group,64 cases in each group. Single drug group received Dydrogesterone tablet with first dose of 40 mg,then 10 mg,q 12 h until vaginal bleeding;combined medication group additionally received 8 g Yunkang granule, tid,until symptoms disappeared. Human chorionic gonadotropin (HCG),clinical symptoms remission time and disappearance time,pregnancy/childbirth complications,pregnancy outcome and neonatal adverse outcome,and the incidence of adverse reac-tions in 2 groups were compared. RESULTS:After treatment,HCG in 2 groups significantly increased,and combined medication group was higher than single drug group,the differences were statistically significant(P<0.05);clinical symptoms remission time and disappearance time in combined medication group were shorter than single drug group,the difference was statistically signifi-cant (P<0.05). There were no significant differences in incidence of pregnancy/childbirth complications,pregnancy outcome and neonatal adverse outcomes in 2 groups (P>0.05). The incidence of adverse reactions in combined medication group was 10.9%, which was significantly lower than single drug group (40.6%),the difference was statistically significant (P<0.05). CONCLU-SIONS:Both dydrogesterone alone and Yunkang granule combined with dydrogesterone show good efficacy in the treatment of ear-ly threatened abortion,but the remission time and disappearance time of clinical symptoms and adverse reactions in combined medi-cation group are less than that in single drug group.

OBJECTIVEThis study aims to investigate the color stability of ceromer with different thicknesses and different types of resin adhesive materials after accelerated aging and provide references for clinical application and selections.

METHODSNine groups of experimental samples were used, and each group contained five samples. We made joint samples with ceromer having three different thicknesses (1.00, 0.75, 0.50 mm) combined with three different resin adhesive materials (RelyX Veneer, RelyX Unicem, Filtek Z350 Flow), respectively. All samples were placed into Xenon Lamp Aging Instrument to implement accelerated aging. Spectrophotometer was used to measure the lightness (L*), red green color value (a*), and blue yellow color value (b*) of all samples before and after accelerated aging. The change of lightness (ΔL), red green color value (Δa), blue yellow color value (Δb), and color variation (ΔE) were also calculated. We investigated the influence of ceromer veneer thicknesses and resin adhesive material types on color variation by two-factor analysis of variance.

RESULTSThe thickness and type factors showed significant influence on ΔE values, and exhibited interactions (P < 0.05). The ΔE values of all experimental groups were lower than 3.3. After the accelerated aging process, all L*, a*, and b* values of the experimental groups decreased and the ΔL values were lower than 2.0.

CONCLUSIONCeromer veneer thickness and resin adhesive material types could affect the color stability of ceromer veneer and resin adhesive materials. The changes in lightness and color in ceromer veneer and resin adhesive materials are considered clinically acceptable after accelerated aging.

OBJECTIVE: To evaluate the relative factors influencing olfactory dysfunction in patients with chronic rhinosinusitis (CRS). METHOD: Visual analogue scale (VAS) was applied to measure the severity of olfactory dysfunction of 270 patients with CRS. Patients were divided into two groups, one was that the quality of life (QOL) of patients was affected by olfactory dysfunction (VAS > 5), the other was that without QOL affected by olfactory dysfunction (VAS ≤ 5). The association between age, gender, nasal polyps, allergic rhinitis, smoking history, early nasal surgery history and other clinical factors, and serum total IgE level, peripheral blood eosinophil count, peripheral blood mononuclear cell count and olfactory dysfunction was analyzed. RESULT: The number of patients with nasal polyps, allergic rhinitis, previous nasal surgeries, the level of serum total IgE, and the severity of edema were significantly increased in patients with impaired QOL associated with olfactory dysfunction (P < 0.05). Sex distribution, age, smoking history, deviation of nasal septum, eosinophil and mononuclear cell count did no statistically differ between the groups with and without impaired QOL associated with olfactory dysfunctions (P > 0.05). Serum total IgE increased (OR = 1.003, P < 0.01) and severe edema (OR = 2.483, P < 0.01) were the risk factors for the impairment of olfactory function, more notably for edema; whereas previous nasal surgeries was a protective factor (OR = 0.408, P < 0.01). CONCLUSION Sever edema and increased serum total IgE are risk factors, whereas previous nasal surgeries history is a protective factor for the olfactory dysfunction.
