Objective To evaluate the methods for improving diagnostic ratio of unruptured ectopic pregnancy with ultrasonography. Methods A total of 139 patients of small adnexal cysts with thick wall were predicted respectively with sonographic indexes. All patients (61 with unruptured ectopic pregnancy and 78 with small corpusluteum) were confirmed postoperatively or with long-term follow up, and the results were compared. Results The diagnostic sensitivity of with hyperecho or isoecho compared with endometrium, hyperecho compared with ovarian tissue, adnexal cyst without small follicle around was 86.89%, 93.44% and 96.72%, and the specificity of three predictors was 93.59%, 85.90% and 70.51%, respectively. Two sonographic indexes together had a sensitivity of 98.36% and a specificity of 94.87% for diagnosing ectopic pregnancy. Conclusion Observing the relation of adnexal cyst and ovarian and the echogenic of cyst wall are specific and sensitive for the diagnosis of ectopic pregnancy.

OBJECTIVE: To observe the effect of formaldehyde inhalation on the allergic rhinitis mice model. METHOD: Forty-eight male BALB/C mice in six experimental group were exposure to (A) saline control; (B) Der p1; (C) formaldehyde (3.0 mg/m3); (D) Derp1 + formaldehyde (1.5 mg/m3); (E) Der p1 + formaldehyde (3.0 mg/M3); (F) Der p1+ formaldehyde (6.0 mg/m3). The concentrations of IL-4, IL-10 and IFN-γ in the peripheral serum were measured by enzyme-linked immunosorbent assay(ELISA). Nasal mucosal inflammation was evaluated by HE staining. Result: Formaldehyde exposure could increase the number of allergic rhinitis mice with sneezing and rubbing nose. The levels of IL-4 and IL-10 in group B, D, E and F were higher than that ingroup A (P < 0.05). Compared with the group C, the group D, E and F could effectively increase serum IL-4 and IL-10. The concentration of IL-4 in group E and F was higher than that of group B, while the group C was lower (P < 0.05). The concentration of IL-10 in group D, E and F was higher than that in group B (P < 0.05). The expression of IFN-γ in group B, D, E and F was lower than that in group A. While, the IFN-γ expression in group B was lower than that of group C and higher than that in group F (P < 0.05). Moreover, the concentration of IFN-γ in group D, E and F was lower compared with group C (P < 0.05). The nasal mucosa HE staining showed that the density of EOS increased simultaneously in formaldehyde exposure allergic rhinitis groups. CONCLUSION The study showed that formaldehyde exposure can promote Th2 cytokines and eosinophil infiltration and then aggravate the allergic rhinitis symptoms.

OBJECTIVE :To give sonic references for improving the quality of drug use and the regulations of pharmacy in China. METHODS: In this paper. OBRA - 90 and the situation of drug use review in America are introduced and analyzed,and inadequate insurance in drug use in China is pointed out.RESULTS & CONCLUSION :The drug use review system in USA is quite successful in ensuring the safety of drug use in public, and we can learn something from it to improve the quality of medication in China.

OBJECTIVE:To optimize the formulation and preparation technology of podophyllotoxin derivative(5-FPE) liposomes.METHODS:A thin film-ultrasonic dispersion method was used to prepare the 5-FPE liposomes.Orthogonal experiment was performed to optimize its best formulation and preparation technology with entrapment efficiency as the evaluation index;meanwhile,the entrapment efficiency,drug-loading amount,morphology,particle size distribution,Zeta electric potential and stabilities of the liposomes within 10 days' storing at 25 ℃ or 4 ℃ were investigated.RESULTS:The optimal formulation and prepariton technology of the liposomes has been established in our study.3 batches of liposomes prepared in the optimal conditions had a mean entrapment efficiency of 66.45%,a mean drug-loading amount of 7.97%,mean particle size of 284.7 nm and mean Zeta electric potential of-22.15 mV.The entrapment efficiency of the liposomes decreased more after storing for 10 days at 25 ℃ than at 4 ℃.CONCLUSION:The optimal formulation and preparation technology of 5-FPE liposomes are feasible and which serve as a basis for the further study of 5-FPE preparations.

Autophagy is a metabolic process whereby intracellular substance is degraded in lysosomes of eukaryotic cells, which plays an important role in cell survival, growth, differentiation and maintenance of cellular homeostasis. The regulatory mechanism by which autophagy contributes to tumorigenesis is complex and also exhibits the effects of a double-blade sword. At the earlier stage of the neoplastic process, autophagy can inhibit the formation of tumor by preventing the accumulation of damaged organelles and accelerating the protein degradation process. However, in the process of tumor development, autophagy can help tumor cells survive under the conditions of hypoxia and nutrient deprivation by degrading and recycling intracellular substances. Prostate cancer is the most common malignant tumor in male genital system. Rrecent studies show that autophagy is closely related to tumorigenesis, and therefore the molecular mechanism of autophagy has been the focus of research. This review focuses on the regulatory mechanism of autophagy in prostate cancer, hoping to provide a theoretical basis of autophagy for the treatment of prostate cancer. Copyright © 2012 by TUMOR.

Objective To analyze three-dimensional contrast-enhanced ultrasonographic(3D-CEUS) features of corpus luteum hematoma,to improve the understanding of the sonographic features of corpus luteum hematoma.Methods 3D-CEUS features of thirty corpus luteum hematoma in twenty-nine cases were analyzed retrospectively and compared with conventional ultrasonography.Results Conventional ultrasonography and 3D-CEUS had statistical differences in the scores of these three parameters of corpus luteum hematoma:the wall(1.20 ± 0.43 vs 2.00 ± 0.00),internal echo(1.77 ± 0.43 vs 1.00 ± 0.00) and whether there being the main blood vessels(1.10 ± 0.31 vs 1.53 ± 0.51) (all P =0.000).Conclusions 3DCEUS can provide valuable information for the differential diagnosis of corpus luteum hematoma.
