Objective Among the factors affecting embryo implantation, oxidative stress is one that receives much medical attention. The purpose of the study was to explore the effect of H2 O2 on the endometrial stromal cells ( ESCs) in the decidual mouse model of oxidative stress of ESCs. Methods Primary ESCs cultured by enzymatic digestion with a mesh filter were divided into a control, an experimental, and a model group. Decidualization was induced in the mice of the experimental and model groups by inter-vention with 10 nM E2 and 1μmol/L P4 for 72 h in vitro. Then, the animals of the model group were treated with different concentra-tions of H2 O2 for 4 hours. The primary ESCs were identified by immunohistochemistry, the expression of dPRP mRNA determined byRT-PCR, the proliferation of the decidual ESCs treated with H2 O2 analyzed by CCK-8, and the level of ROS detected by flow cytometry. Results Primary mouse ESCs were successfully isolated, cultured, and identified, which were shaped like spindles and polygons, radial-ly aligned under the microscope. Immunofluorescence analysis showed positive expression of vimentin and negative expression of cytokeratin. The purity of the primary mouse ESCs was ( 96. 3 ± 0. 49 )%. Theexpression of dPRP mRNA was significantly higher in the ESCs treated with E2 and P4 than in the control (0.0002±0.0000 vs 1.0010±0.0011, P<0.01). H2O2 at ≥150μmol/L suppressed the proliferation of the decidual ESCs by 6.9% (P<0.05), and in a concen-tration-dependent manner, reaching the maximum inhibition rate of 70.6% at the concentration of 300μmol/L. The level of intracellular ROS was markedly increased in the ESCs treated with H2O2 at 50μmol/L (27.77±4.20) and 100μmol/L (43.57±6.58), with statisti-cally significant difference from that in the control group (17.47±0.61) (P=0.001). Conclusion H2O2 at 100μmol/L can signifi-cantly elevate the intracellar ROS level without affecting the proliferation of decidual primary ESCs, and therefore can be used for estab-lishing the model of oxidative stress of ESCs in decidual mice.

New registry classifications of chemical drugs redefined the concepts of new drugs and generic drugs. New drugs emphasize the international innovation including innovate new drugs and modified new drugs. Modified new drugs are improvement of drugs already on the market to achieve superior efficacy. With the advantages of high success rate,high return,low risk and long life cycle,modified new drugs have become the mainstream of new drugs research and development in the world. Modified new drugs R&D in China should be based on clinical demand and focused on the differentiation research in order to obtain new preparations with signif-icant clinical advantages to better serve the clinical practise. This paper states the concept and characteristics of modified new drugs in China,makes case analysis and shares the development history of blockbuster modified new drugs in the world,clarifies the opportuni-ties and challenges and provides ideas for the future development of modified new drugs in China.

Objective To establish an animal model of dermatophytosis and to evaluate antifungal efficacy on dermatophytosis with this model. Methods Animal models of dermatophytosis were established by inoculating dermatophyte suspension onto abraded skin on the back of guinea pigs. Thirty- eight healthy guinea pigs were randomly and equally divided into 2 groups, namely, Trichophyton mentagrophytes group (infected with T. mentagrophytes), and Microsporum canis group (infected with M. canis), and each group was classified into three subgroups, i.e., itraconazole group treated with oral itraconazole of 4 mg per kilogram body weight per day from day 0 to day 14 after infection, terbinafine group treated with oral terbinafine of 5 mg per kilogram body weight per day from day 0 to day 14 after infection, and untreated group receiving no therapy. The therapeutic effect was evaluated according to skin lesion score and fungal examination results on day 8, 11 and 14 after infection. Results Obvious lesions were observed and fungal examination was positive in untreated, infected pigs on day 8 after infection. In T. mentagrophytes-infecyted pigs, the skin lesion score on day 8, 11, 14 was 9, 1 and 0 in itraconazole group, 8, 5, and 1 in terbinafine group, 48, 52, 40 in untreated group, respectively, and there was significant difference between treated and untreated groups on the three time points (all P<0.01); the mycological cure rates on the above time points were 66.7%, 83.3%, 83.3%, in itraconazole-treated pigs, 83.3%, 83.3%, 83.3%, in terbinafine-treated pigs, 0, 0, 0 in untreated pigs, respectively, with no significant difference between itraconazole and terbinafine group (all P>0.05) but statistical difference between untreated and treated groups (all P<0.01) on all time points. Meanwhile, in M. canis-infected pigs, the skin lesion score on day 8, 11, 14 reached 3, 0, 0 in itraconazole group, 9, 2, 0 in terbinafine group, 46, 47, 39 in untreated group, respectively, and mycological cure rates 83.3%, 83.3%, 83.3% in itraconazole group, 83.3%, 83.3%, 83.3% in terbinafine group, 0, 0, 0 in untreated group, respectively; significant difference was noticed in the two parameters between the treated and untreated groups (all P<0.01) but not between the two treated groups (all P>0.05). Conclusion Itraconazol and terbinafine exhibit similar excellent antifungal activity in routine model of T. mentagrophytes-and M. canis-dermatophytosis.

Objective To evaluate the diagnostic significance of full-field digital mammography (FFDM)for atypieal breast cancer findings.Methods Seven hundred-eighteen cases with breast cancer were examined using FFDM and atypical mammographic findings were found in 134 cases.Craniocaudal (CC)view and mediolateral oblique(MLO)view were conducted for each patient.Mediolateral view or spot view Was achieved if necessary.Preoperative localization Was conducted for the patients with nonpalpable breast cancer8.Results (1)The masses with well.circumscribed margin on mammography were more common in infiltrating duetal carcinoma(22/106),mucinous carcinoma(8/10),medullary carcinoma (5/6),and increased with age and reduction of the mass density.(2)Long spieulation,architectural distortion,patchy high density were mainly found in infiltrating ductal carcinoma and 30-40(24 cases),41-50(34 cases)years old patients.Long speculation wag mainly found in 30-40 years old patients (10/30).(3)Hish homogenous density and subcutaneous edema in the entire breast and mass-like area were most ffequendy found in infiltrating ductal carcinoma at 30-40(2 cases)and 41-50(5 cases)years old.High density and subcutaneous edema were only found in dense breast(8 cases).Conclusion The atypical findings of breast cancer in foil-field digital mammography are associated with the pathological type of cancer.patient age and the gland density of the breast.

Objective To explore the efficacy and tolerability of sorafenib in combination with interferon-α-2b for Chinese patients with metastatic renal cell carcinoma. Methods Seventeen pa-tients with unreseetable metastatic renal cell carcinoma were enrolled and received sorafenib in combi-nation with interferon-α-2b. Sorafenib was continuously given at the dose of 400 mg twice per day, in-terferon-α-2b 300 MIU subscutaneously once per day for 5 d each week, until disease progression or intolerable toxieities occurred. Tumor responses were evaluated every two months by response evalua-tion criteria in solid tumor. Results The median treatment duration was 120(51-442)d. All 17 pa-tients were evaluable for efficacy and safety. Five patients achieved partial responses (PR), 1 uncon-firmed PR,9 stable diseases. Two patients had progressed diseases. The overall response rate was 29%(5/17)with the disease control rate of 88%(15/17). Due to short-time follow up, the median progression free and overall survival time were not yet available. The common side effects included: fever 82%(14/17), diarrhea 82%(14/17), hand-foot syndrome 71%(12/17), asthenia 65%(11/17), rash 53%(9/17), alopecia 41% (7/17), mucosities 41% (7/17), hypertension 29% (5/17), anorexia 24% (4/17), hoarseness 24% (4/17), myalgia 24 % (4/17), nausea/vomiting 12 % (2/17) and headach/ dizzle 12%(2/17). Eleven (65%) out of 17 patients developed neutropenia, 5(29%) thrombocytope-nia and 5 (29%)anemia. Four(24%) out of 17 patients had abnormally elevated ALT/AST. Conclu-sion Sorafenib in combination with interferon-α-2b for metastatic renal cell carcinoma improves re-sponse rate with manageable toxicity.

Objective To study the clinical characteristics, the laboratory profile (CD4+ and CD8+ counts and CD4+/CD8+ ratio) and the efficacy of antifungal treatment in HIV/AIDS patients with oropharyngeal candidiasis. Methods Oral lesions were evaluated among 20 HIV/AIDS patients with oropharyngeal candidiasis and the controls who were HIV-negative patients with oropharyngeal candidiasis. Samples were obtained from the lesions for fungal examination by microscopy and culture. The flow cytometry was used for detection of CD4+ and CD8+ counts in peripheral blood. Treatment efficacy of itraconazole was assessed among study group and the control group after treatment for one week, two weeks, at the end of treatment, as well as two weeks after treatment. Results Out of 20 HIV/AIDS patients, 19 were infected with Candida albicans and one with Candida parapsilosis. Six cases had infection on the tongue and 14 on the mucous membrane of oral cavity. CD4+ and CD8+ counts, and CD4/CD8 ratio were 119.40?127.43, 652.50?338.57 and 0.163?0.13, respectively. Mycologic clearance rates were 16.67%, 50.00%, 61.11% and 66.67%, respectively, after treatment with itraconazole for one week, two weeks, at the end of treatment, and two weeks after treatment. Conclusions Oropharyngeal candidiasis is a complication occurred in HIV/AIDS patients, and Candida albicans is the most common pathogen of the infection. The tongue and mucous membrane of oral cavity are usually involved in the patients. The therapeutic efficacy is related to the status of immunity.
