ObjectiveTo observe the clinical effect of methotrexate combined with mifepristone in the treatment of unruptured ectopic pregnancy.Methods96 cases of unruptured ectopic pregnancy patients were randomly classified into two groups,observation group with 48 cases was treated with methotrexate combined with mifepristone and control group with 48 cases was only treated with methotrexate.The treatment effect and adverse reaction between two groups were compared.ResultsThe time of blood β-HCG recovery to normal and hospitalization time in observation group were significantly shorter than those in control group( P ＜ 0.05 ),and mass diameter was significantly smaller than that in control group( P ＜ 0.05 ).The adverse reaction incidence in observation group was 10.4％ ( 5/48 )while 6.3％ (3/48) in control group.ConclusionMethotrexate combined with mifepristone in the treatment of unruptured ectopic pregnancy could enhance clinical effect,shorten treatment time,decrease adverse reaction,which could be applied in clinic.

Objective To study the dependablity of clinical characteristics and prognosis in patients with endometrial cancer,so as to apply the basis for the treatment. Methods The clinical and pathological data of 92 patients with endometrial cancer were analyzed retrospectively, 5-year survival rate was followed and observed. Using Cox proportional hazard regression analysis to evaluate the factors related to overall survival. Results The overall 5-year survival rate was 72.41%. Using univariate analysis, the survival time was correlated with histologic type, pathological staging, histologic grade, myometrium invasion,cervical invasion and lymph node metastasis (P＜0.05).Using multivariate analysis, the survival time was correlated with histologic type,histologic grade and myometrium invasion. Conclusions Histologic type, histologic grade and myometrium invasion are independent prognostic factors for survival time of patients. In order to improve the prognosis of the patients, they should be treated by individual therapies.

Objective To evaluate the role of angiotensin Ⅱ receptors in the development of neuropathic pain (NP) in rats.Methods Seventy-five male Sprague-Dawley rats,weighing 230-270 g,were randomly divided into 5 groups (n =15 each) using a random number table:sham operation group (group S),group NP,telmisartan (angiotensin Ⅱ receptor antagonist) 2 mg group (group T1),telmisartan 5 mg group (group T2),and telmisartan 10 mg group (group T3).NP was induced by chronic constrictive injury (CCI) in chloral hydrateanesthetized rats.The sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4-0 silk thread.In S group,the sciatic nerves were exposed but not ligated.Telmisartan 2,5 and 10 mg/kg were perfused via stomach once a day for 14 consecutive days in T1,T2 and T3 groups,respectively,while the equal volume of normal saline was given instead of telmisartan in S and NP groups.Mechanical and thermal pain thresholds were measured at 1 day before CCI and 3,7 and 14 days after CCI in each group.Results The mechanical and thermal pain thresholds were significantly decreased after CCI in NP,T1,T2 and T3 groups as compared with group S.The mechanical and thermal pain thresholds were significantly increased after CCI in T1,T2 and T3 groups as compared with group NP.The mechanical and thermal pain thresholds were significantly higher after CCI in T2 and T3 groups than in group T1.There was no significant difference in the mechanical and thermal pain thresholds between T2 and T3 groups.Conclusion Angiotensin Ⅱ receptors are involved in the development of NP in rats.

BACKGROUND:Chronic hepatitis B virus infection can impact the biological characteristics of bone marrow mesenchymal stem cel s. Adipose-derived mesenchymal stem cel s have gained more and more attention due to their high safety, little invasiveness, easy purification and rapid proliferation. OBJECTIVE:To establish the isolation and culture method of adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection in vitro, and to observe the biological characteristics of cel s. METHODS:Adipose-derived mesenchymal stem cel s were isolated from the subcutaneous fat of hepatitis B virus infection patients by col agenase digestion and adherent method. Growth curve of adipose-derived mesenchymal stem cel s were detected by MTT method and cel phenotypes were detected by flow cytometry. The adipogenic and osteogenic differentiation potential of adipose-derived mesenchymal stem cel s were detected in vitro. RESULTS AND CONCLUSION:(1) Adipose-derived mesenchymal stem cel s from 10 patients with hepatitis B virus infection were al isolated and cultured successful y. The primary passage time of adipose-derived mesenchymal stem cel s was (8.3±1.2) days. The growth curve of cel s was“S”shaped. Cel s came into a logarithmic phase at days 3-4, and came into platform at day 7. (3) Passage 3 adipose-derived mesenchymal stem cel s highly expressed CD29, CD166, HLA-ABC and CD44, but did not express or lowly expressed CD34 and HLA-DR. (3) Adipose-derived mesenchymal stem cel s differentiated into adipocytes after adipogenic induction, and differentiated cel s were positive for oil red O staining;after osteogenic induction, adipose-derived mesenchymal stem cel s differentiated into osteoblasts that were positive for alkaline phosphatase staining. These findings indicate that the col agenase digestion and adherent method can be used to effectively isolate adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection, and the cel proliferation is rapid so that a large number of cel s can be obtained in the short term.
