The association between polyomaviruses JC infection and gynecologic tumors / 病毒学报

The JC virus is a widely infected human polyomavirus. Recent foreign researches showed that the JC virus infection is correlated with tumors of nervous system and digestive system, while, and study on the relationship between JC virus infection and gynecological tumor is seldom reported. In this study, we first establish the nucleic acid detection methods and procedures for JC virus and its highly homologous BK virus. The JC and BK viruses infection was evaluated by detect the viral DNA in samples including biopsy tissues, serum as well as urine of myoma of uterus (98 cases), cervical cancer (84 cases), endometrial cancer (40 cases) and ovarian tumor (72 cases) patients. The BK viral DNA positive rate was significantly higher in urine samples than that of blood and biopsy samples, and there is no significant difference of the BK viral DNA positive rate among all patient groups. The JC viral DNA positive rate is almost 0 in serum samples and biopsy. tissues, however, viral DNA positive rate is more than 50% in urine samples. In fibroids group, the JC viral DNA positive rate is up to 65. 3% which is significantly higher than that in other patients groups and healthy control. Further gynecological tumor associated viruses detection showed that only human papilloma virus infection is associated with cervical cancer, the herpes simplex virus, EB virus and cytomegalovirus infection is extremely low in our patient groups. No synergistic effect on gynecological tumor caused by viruses co-infection was observed. Our study showed that JC virus infection is highly related to the pathogenesis of uterine fibroids.

Conventional repair, prolift system and gynemesh system in total pelvic floor reconstruction: A comparison / 第二军医大学学报

Objective To compare the conventional repair, Prolift system and Gynemesh system in total pelvic floor reconstruction. Methods Forty patients with pelvic organ prolapse (POP), who were treated in our department from March 2009 to March 2011, were included in the present study. Fifteen cases were in the conventional repair group, 10 in the Prolift system surgery, and the other 15 in the Tongshi group (revised total pelvic floor construction with Gynemesh). The pre-, peri-operative data and follow-up results were compared between the 3 groups. Results The body mass index, menopause age, pregnant times and the degrees of prolapses were comparable in the 3 groups (P>0. 05). The degrees of anterior and posterior vaginal proplase and uterus proplase were not significantly different between the 3 group (P>0. 05). The intro-operative blood loss, highest body temperature, residual urine, operation time, and hospital stay were not significantly different between the 3 groups (P>0. 05). The follow-up rate was 100% for the Prolift group, with a mean time of (5. 8 + 2. 0) months; one case developed erosion in the anterior vaginal wall and one had I stress urinary incontinence. The follow-up rate was 93.3% in the Gyenmesh group, with a mean time of (9. 1 + 2. 0) months; one case had chylous ascites after whole pelvis suspension and one had recurrent anterior vaginal proplase POP-Q Tl • The follow-up rate was 100% in the classical group, with a mean time of (9. 1 + 5. 0) months; anterior and posterior vaginal proplase POP-Q Tl were each found in one case. Conclusion Conventional repair, Prolift system and Gynemesh system are all safe and suitable for total pelvic floor reconstruction, and they have no difference concerning the short-term clinical outcomes and complications.

Effects of retinoic acid on proliferation and differentiation of a human ovarian carcinoma cell line: 3AO / 中国医学科学杂志(英文版)

<p><b>OBJECTIVE</b>To observe the effects of retinoic acid (RA) on the proliferation and differentiation of a human ovarian carcinoma cell line: 3AO cells.</p><p><b>METHODS</b>3AO cell proliferation was evaluated by viable cell count, percentage of cells in each cycle phase were analyzed by flow cytometric analysis, alkaline phosphatase (AKP) activity was determined as described, and CA125 expression was measured by ELISA.</p><p><b>RESULTS</b>RA could inhibit the proliferation of 3AO cells accompanied with morphological changes in a dose-dependent manner. Cell cycle analysis indicated that RA inhibition of 3AO cells growth occurred through induction of G1 arrest with a concomitant reduction in the proportion of cells in S phase, AKP activity increased significantly after treatment with RA (0.1 micromol/L) for 1-5 days. Dose-response studies revealed that the AKP activity increased to a different extent as a function of RA concentrations. Furthermore, RA could suppress the expression of CA125 tumor marker in 3AO cells.</p><p><b>CONCLUSION</b>RA could markedly inhibit the proliferation and induce the differentiation of 3AO cells.</p>

Diagnosis and treatment of 40 cases of hyperthyroidism in pregnancy / 第二军医大学学报

Objective: To study the diagnosis， treatm ent and outcome of infants in patients with hyperthyroidism in pregnancy. Methods: The levels of T3，T4，TSH，FT3，FT4 in 40 cases of hyperthyroid gravida and control group were measured before delivery, the r oute of delivery and the outcome of infants were studied, and the neonatal thyroid f unctions were evaluated by the levels of T3，T4，TSH in cord serum samples . Results: The levels of T3，T4，FT3，FT4 in non-treatm ent group were higher than that of treatment group and control(P<0.01); an i ncreased rate of forceps and cesarean in hyperthyroid gravida was seen compared with that in control group, about 90%(36/40); the body weights of infants in no n-treatment group were lower than that in treatment and control group. There wa s a case of neonatal hyperthyroidism in non-treatment group. Conclusion : Hyperthyroidism should be diagnosed and treated earlier and there is little side effects on the outcome of infants.

Fetal Bone Marrow Stromal Cells in Cooperation with Exogenous Cytokines Support In Vitro Expansion of Cord Blood CD34(+) Cells / 中国实验血液学杂志

To elucidate the role of fetal bone marrow stromal cells (FBMSC) in cooperation with exogenous cytokines in supporting the in vitro expansion of cord blood CD34(+) cells which were purified by negative immunomagnetic selection, FBMSCs were cultured with different combinations of cytokines including SCF, IL-3, IL-6, FL, G-CSF and EPO in a 14-day liquid culture system. The results showed FBMSC plus SCF, IL-3, IL-6, FL and EPO was the most effective combination which increased total nucleated cells, CFU-GM, BFU-E and CD34(+) cells by (692.4 +/- 52.7) fold, (237.1 +/- 106.6) fold, (114.8 +/- 32.8) fold and (25.3 +/- 10.1) fold, respectively. Our studies indicated that fetal bone marrow stromal cells combined with above-mentioned cytokines can efficiently expand cord blood CD34(+) cells.
