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.

OBJECTIVE To study the antitumor activity and underlying mechanisms of Xiaoaiping injection(Xap)combined with gefitinib(Gef)in nude mice bearing resistant non-small cell lung cancer (NSCLC) cells H460 or H975. METHODS BALB/c nude mice were inoculated with human NSLCL cells H460 or H1975 and the drug treatment did not start until the tumor volume reached 50-100 mm3. The tumor bearing mice were divided into four groups:control group,Xap group(5 g · kg-1,ip),Gef group (50 mg · kg-1,ig),and Xap plus Gef group. All the administration lasted for 21 d continuous. Tumor volumes were measured two or three times per week,and the body weight of animals was re-corded. At the end of the test,tumors were weighed after the sacrifice of mice. Tumor inhibition rate and relative tumor proliferation rate were calculated based on tumor weight and tumor volume. The related biomarkers and proteins in tumor tissues were detected by immunohistochemistry and Western blot assay, respectively. RESULTS Compared with the control group,no significant effect was observed on the growth of H460 and H1975 xenografts in groups of Xap or Gef alone in nude mice. However,the two-drug combination significantly suppressed tumor volume,with (1103 ± 340) versus (3020 ± 450) mm3 for H460 and(487 ± 153)versus(1269 ± 161)mm3 for H1975,respectively(P<0.05). The combined Xap and Gef application also significantly reduced the tumor weight,with(1.20±0.52)versus(2.78± 0.93)g for H460 and(0.52 ± 0.32)versus(0.92 ± 0.42)g for H1975,respectively(P<0.05). The relative tumor proliferation rate and inhibition rate in the combination group was 42.1%and 43.5%for H460(P<0.01),43.0%and 52.5% for H1975(P<0.01). Compared with Xap and Gef drug alone,their combination showed significant difference in reducing tumor weight,suppressing tumor proliferation rate and increasing tumor inhibition rate(P<0.05). Immunohistochemistry results showed that each drug alone had no effect on tumor angiogenesis markers of vascular endothelial growth factor(VEGF)and CD105 expression,or on drug resistance related proteins of p-ERK,p-Akt and p-mTOR,whereas the combination of Xap and Gef obviously reduced the expression of these biomarkers in H460 and H1975 tumor tissues. The decreased drug resistance related proteins of p-PI3K and its downstream molecules p-Akt,p-ERK and p-mTOR by the two-drug combination were also confirmed by Western blot results(P<0.01,compared with control), and showed significant difference compared with each single treatment(P<0.05). CONCLUSION The addition of Xap significantly improves the antitumor activity of Gef in H460 and H1975 xenografts,and this synergistic effect may be ascribed to the inhibition of tumor angiogenesis,the down-regulation of PI3K and its downstream signaling molecules which are associated with drug resistance.

Objective To evaluate characteristics of CT and 18F-FDG PET/CT in pulmonary sclerosing hemangioma (PSH).Methods A retrospective study involving 12 patients (2 males,10 females;24-80 years old) confirmed as PSH by pathology from May 2012 to July 2014 was investigated.All patients underwent chest CT scan,including enhanced CT;and 5 cases underwent whole-body 18F-FDG PET/CT.All imaging data were collected and analyzed to find out a more effective diagnostic method.Results In 12 PSH patients,9 had single lesion,of which 4 involved left lung and 5 right lung.The rest 3 patients including 1 with two nodules located in the right lower lobe,and 2 with multiple nodules scattered in several lobes.Plain CT showed all lesions had uniformly isodensity,4 with calcification,3 with air meniscus sign.Contrast-enhanced CT examinations showed that the majority lesions were prominent enhancement and few moderate enhancement,all lesions showed vessel marginating sign and 6 with cystic and necrosis area.18F-FDG PET/CT examinations showed that the lesions displayed patchy pattern of mild to moderate uptake with SUVmax 2.2--4.0.Conclusions The characteristic CT features of PSH,especially the contrast-enhanced CT imaging,are important for diagnosis.18F-FDG PET/CT findings are extremely helpful in differentiating PSH from malignant lesions.
