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.

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 study the expression of tumor stem cell marker aldehyde dehydrogenase 1 (ALDH1)in invasive bladder cancer tissue and to clarify its relationship with the biological behavior of bladder cancer. Methods The ALDH1 expression in 109 cases of primary invasive carcinomas specimens (case group)and 20 cases of normal bladder tissue surrounding cancer (control group)was detected by immunohistochemistry. At the same time,the ALDH1 expression in 6 cases of metastatic pelvic lymph node tissue and 20 cases of non-metastatic pelvic lymph node tissue was detected. The relationship between the ALDH1 expression and the chinicopathological charateristics of invasive bladder cancer and its influence in the survival rate and disease-free survival were analyzed. Results The positive rates of ALDH1 expression in bladder cancer tissue and normal bladder tissue were 33.94%(37/109)and 5.00% (1/20),respectively,there was significant different between them (P<0.01);they were 19.05% (8/42)and 43.28% (29/67)in the cases with non muscle invasive and nmuscle invasive bladder cancer, respectively,there was significant difference (P<0.01);they were 13.04% (3/23)and 39.53% (34/86)in the cases of bladder cancer with low grade and high grade,respectively,there was significant difference (P<0.05);they were 50.00% (3/6)and 12.90% (4/31)in the tissue of bladder cancer with metastatic lymph nodes and non metastatic ones,respectively,there was significant difference (P<0.05);they were 50.00% (3/6)and 0.00%(0/20)in the metastatic lymph nodes and non metastatic ones,respectively,there was significant difference (P<0.01).The overall survival rate in the patients with positive ALDH1 expression was 64.9% while it was 84.7% in negative ones,there was significant difference (P<0.05);the disease-free Survival was 51.4% and 75% in the patients with positive and negative ALDH1 groups,respectively,there was significant difference (P<0.05). Conclusion The high expression of tumor stem cell marker ALDH1 is associated with staging, grading and prognosis of invasive bladder cancer.ALDH1 may play a role in the tumorigenesis,progression and metastasis of bladder cancer.

Objective To observe the changes of serum ferritin and 25-(OH) vitamin D3 in patients with diabetic cranial neuropathy.Methods There were 50 patients without diabetic Cranial neuropathy,46 patients with diabetic cranial neuropathy,and 40 cases of normal control group.The changes of serum ferritin and 25-hydroxy vitamin D3 were observed in each group.The correlation between two indexes and the correlation with diabetic cranial neuropathy were analzyzed.Results The serum ferritin levels in diabetic group and diabetic neuropathy group were significantly higher than those in normal control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(687.54 ± 65.38)ng/ml] was significantly higher than that of patients without diabetic cranial neuropathy [(497.28 ± 46.39) ng/ml,P ＜0.01].The serum 25-(OH) vitamin D3 levels in the diabetic group and diabetic neuropathy group were lower than those in the control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(26.45 ± 8.93)nmol/l] was significantly less than that of patients without diabetic cranial neuropathy [(37.19-± 9.74)nmol/L,P ＜ 0.01].Serum ferritin levels were positively correlated with 25-(OH) vitamin D3 (r =-0.59,P ＜ 0.01).Multivariate unconditional Logistic regression analysis showed that diabetic neuropathy was negatively correlated with 25-(OH) vitamin D3 (P ＜ 0.05).Conclusions The increases of serum ferritin and 25-(OH) vitamin D3 are closely related to the occurrence and development of diabetic cranial neuropathy,which provides the theoretical basis for clinical intervention therapy.
