Objective To explore the value of transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) in diagnosing adult multiple atrial septal defect (MASD). Methods Thirty adult patients with MASD were examined with TTE, 25 patients were examined also with TEE, 26 patients were examined with cardiac catheterization as well. Transcatheter closure of MASD was performed in 20 patients and succeeded in 18, while open-chest operation was performed in 4 patients. Results Foramen secundum atrial septal defect was diagnosed with both TTE and TEE with an accuracy rate of 60.00% (18/30) and 96.00% (24/25), respectively. The main color Doppler flow imaging (CDFI) feature of adult MASD was multiple colorful left-to-right shunt signals through the atrial septal designated, i.e. colander sign of CDFI. Conclusion TTE has some difficulties and TEE has specific value in diagnosing adult MASD. TTE can be used before open-chest operation. TEE is necessary before transcatheter occlusion to make sure of the amount and location of atrial septal defect.

Pelvic organ prolapse (POP) is a common gynecological disease caused by pelvic floor fascia and ligament relaxation in middle-aged and elderly women. A large number of studies have shown that oxidative stress (OS) is one of the core mechanisms of POP. Mesenchymal stem cells (MSCs) are a research hotspot in regenerative medicine. Many evidences show that MSCs can play antioxidant properties in myocardial infarction, hyperoxic lung injury and other diseases, thus reducing inflammation and oxidative stress.In addition, microvesicles (MVs)derived from MSCs secreted can replicate the functions of MSCs through protein, mRNA, miRNA and lipid transport, and participate in many biological processes regulating tissue homeostasis and disease physiology and pathology. This article reviews the potential positive effects of MSCs-MVs in the treatment of POP through antioxidant stress.

Objective To analyze the outcomes and the prognostic factors of hematopoietic stem cell transplantation (HSCT) in combination with imatinib for Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL). Methods All 32 patients with Ph+ ALL achieved hematologic complete remission (CR) at time of transplantation, including 27 cases in the first CR (CR1) and 5 in CR2. Nineteen patients achieved molecular remission (MR). Among 32 patients, 4 received autologous HSCT (AHSCT), and 28 allogeneic HSCT (allo-HSCT). The conditioning regimens comprised of total body irradiation (TBI), cyclophosphamide, fludarabine and cytarabine. The median number of transfused mononuclear cells was 5. 6 × 108/kg, and that of CD34+ cells was 2. 94 × 106 /kg. Thirty-one patients were administrated imatinib orally before transplantion, at a dose of 400～600 mg/day, and 16 patients after transplantation, including 7 for prevention at a dose of 300～400 mg/day and 9 for salvage treatment at a dose of 400 ～ 600 mg/day. Results Hematopoietic reconstitution was achieved in all 32 patients. Three-year estimate of overall survival (OS) was (62. 1±8. 6)%, leukemia-free survival (LFS) (59. 2 ± 8. 7)%, relapse rate (RR) (17. 7 ± 7. 2)% and transplant-related mortality (26. 2 ± 8. 0) %. All 4 undergoing AHSCT were alive, and 3 out of them were in continuous CR with durations of 14, 18 and 67 months respectively. The univariate analysis for prognosis in allo-HSCT showed that the OS of HLA-matched sibling donors group was 76. 5 %,higher than that of unrelated or haploidentical donors group (27. 3 %, P＜0. 05), and so was LFS (70. 6 % vs 27. 3 %, P＜0. 05). RR in patients achieving MR at time of transplantation was 5. 6 %,lower than that in those not achieving MR (40. 0 %, P＜0. 05). RR in patients in CR1 at time of transplantation was 12. 5 %, lower than that in those in CR2 (50 %, P ＜0. 05). Conclusion Imatinib improved the outcomes of HSCT for Ph+ ALL, especially to patients achieving MR at time of transplantation and transplantation in early stage (CR1).

Objective: To explore the effects of hnRNP E1 and both early genes E2 and E6 of HPV16 as well as their interactions in the progression of cervical carcinogenesis. Methods: Subjects of this study included 56 women with normal cervix (NC), 58 patients with low-grade cervical intraepithelial neoplasm (CINⅠ) and 50 patients with high-grade cervical intraepithelial neoplasm (CINⅡ/Ⅲ) who were all recruited from the 'Cervical Lesions Study Cohort Project’ in Jiexiu of Shanxi province from June to September, 2014. Another 40 patients with cervical squamous cell carcinoma (SCC) were from the Shanxi Tumor Hospital during the same period. Information related to cervical lesions were collected, using a structured questionnaire, with cervical tissues and cervical exfoliated cells gathered from all the participants. HPV infection was detected by flow-through hybridization, while the levels of expression on hnRNP E1, HPV16 E2 and E6 protein were measured by Western Blot. Kruskal-Wallis H test, χ² test, trend χ² test were analyzed by SPSS 22.0 software, while interaction was evaluated by generalized multifactor dimensionality reduction (GMDR). Results: The overall infection rates of HPV16 related to CINⅠ (15.52%, 9/58), CINⅡ/Ⅲ (40.00%, 20/50) and SCC (67.50%, 27/40) groups were all higher than that of the NC group (8.93%, 5/56) and with an increasing trend on the severity of cervical lesions (trend χ²=43.613, P<0.001). The levels of expression on hnRNP E1 protein were significantly different in the groups with different cervical lesions (H=9.98, P=0.019), showing a decreasing trend with the severity of cervical lesions (trend χ²=9.495, P=0.002). The levels of expression on HPV16 E2 (H=16.20, P=0.001) and HPV16 E6 (H=15.44, P=0.001) were significantly different in groups with different cervical lesions. Results of GMDR showed that the best interaction model in both groups of CINⅡ/Ⅲ and SCC appeared as hnRNP E1 low expression, HPV16 E2 low expression and HPV16 E6 high expression. However, no similar interaction was seen in CINⅠ (P>0.05). Conclusions Both low expressions of hnRNP E1 and abnormal expression of HPV16 E2 and E6 could increase the risk of high-grade CIN and cervical cancer. It seemed that they might have an important synergistic effect on the progression of cervical cancer.
