OBJECTIVE:To observe therapeutic efficacy and safety of low-molecular-weight-heparin-sodium combined with dy-drogesterone in the treatment of threatened abortion. METHODS:Medical information of 72 patients with threatened abortion were analyzed retrospectively and divided into control group(36 cases)and observation group(36 cases). Control group was given Dy-drogesterone tablet with initial dose of 40 mg,one day later every 12 h 10 mg/time. Observation group was additionally given ab-dominal subcutaneous injection of Low-molecular-weight-heparin-sodium injection 5000 U,once a day,on the basis of control group. Both groups were treated for a week. Clinical efficacies of 2 groups were observed,and lumbar acid,vaginal bleeding,ab-dominal pain time,total treatment time,neonatal birth weight were also observed. The levels of hs-CRP,fibrinogen,D-dimer and platelet,the occurrence of ADR were observed before and after treatment. RESULTS:The total response rate of observation group was significantly higher than that of control group(91.7%vs. 80.6%),the backache,vaginal bleeding,abdominal pain time and to-tal treatment time of observation group were significantly shorter than those of control group,the neonatal birth weight and gesta-tional age of observation group were significantly more than those of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the levels of hs-CRP,fibrinogen,D-dimer and platelet between 2 group(P>0.05);after treatment,the levels of hs-CRP,fibrinogen,D-dimer and platelet in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Based on routine treatment,low-molecu-lar-weight-heparin-sodium combined with dydrogesterone shows good therapeutic efficacy and safety for threatened abortion.

Objective To explore the influential factors of dangerous placenta previa pathogenesis,and to analyze their peri natal period outcomes.Methods The clinical data in 143 pregnant women and parturients of dangerous placenta previa(research group) and 286 pregnant women and parturients of non-dangerous placenta previa(control group) in our hospital from January 2011 to December 2015 were retrospectively analyzed.Results The average age of the research group was higher than that of the control group (t =2.92,P =0.004);the previous pregnancy frequency,previous parity,previous abortion frequency,previous cesarean delivery frequency and incidence of placenta previa in the research group were higher than those in the control group(P＜0.01);the incidence of placenta previa in the research group was higher than that in the control group(x2 =7.60,P=0.006);the prenatal gestational weeks of the research group were lower than those of the control group(t=-12.33,P＜0.01).The multi-factor analysis showed that the age,previous abortion frequency and previous cesarean delivery frequency were the influence factors of placenta previa occurrence.Among them,the previous cesarean delivery frequency was the main risk factor.The occurrence rates of antepartum hemorrhage,postpartum hemorrhage,uterine removal and premature infants in the research group were higher than those in the control group(P＜0.01);The intraoperative blood loss of the research group was higher than that of the control group(P＜0.05);the neonatal birth weight and the 1 min Apgar score of the research group were lower than those in the control group(P＜0.05).Conclusion The age,previous abortion frequency and previous cesarean section frequency are related to the occurrence of dangerous placenta previa.

Tunneling nanotubes(TNT) are cellular communication and transport mechanism discovered recently. TNTs play important role in immunological response and viral spread, also may involve embryonic development, regulation of gene expression and carcinogenesis. However, it was not easy to study TNT for clinical samples since intricate assay method for TNT. We suggested using histochemical assay PAS staining in cell drip to show TNT in leukemia and lymphoma samples.

BACKGROUND: Ureaplasma urealyticum may cause female genital tracts infection and lead sterility, infertility and spontaneous abortion. But it still is not clear whether Ureaplasma urealyticum is one of the factors responsible for fetal malformation.OBJECTIVE: To investigate whether Ureaplasma urealyticum is one of the key factor responsible for fetal malformation.DESIGN: Non-randomized observation of compromised children and their parents with concurrent control.SETTING: The department of immunology and microbiology of a medical college.PARTICIPANTS: Totally 16 malformed fetuses(3 female and 13 male cases) and their parents were chosen from the family seeking pregnancy care in the Department of Gynecology and Obstetrics of the First Affiliated Hospital of Luzhou Medical College and Luzhou First People's Hospital from 1995 to 1997.METHODS: Ureaplasma urealyticum detection was performed in 16 samples of the umbilic blood of the malformed fetuses, sperms of the father, and cervical mucus of the mother who conceived the malformed fetus. The 11 couples positive for Ureaplasma urealyticum were treated with macrolides and aminoglycoside antibiotics and followed up for the outcome of the following pregnancy.MAIN OUTCOME MEASURES: The relation between Ureaplasma urealyticum infection and fetal malformation was examined.RESULTS: Totally 11 of the 16 umbilical blood samples(69% ) were positive for Ureaplasma urealyticum, and serological tests of parents in the 11 positive cases detected rubella virus, cytomegalovirus or Toxoplasma gondii antibodies, nor was abnormality found in chromosomal examination. The following pregnancies and delivery were followed up in 4 women, and the babies showed no functional or organic abnormities with good development till the age of 2 years.CONCLUSION: Female genital tract Ureaplasma urealyticum infection is related to fetal malformation, which provides evidence to support interventions of the occurrence of fetal malformation.

Objective To investigate the MRI features of pilomyxoid astrocytoma ( PMA ) in children.Methods MRI features of seven children with pathologically proven PMA in 2011-2013 were retrospectively analyzed.The ages of the patients ranged from 10 months to 32 months at initial diagnosis.Results All tumors were well-circumscribed masses.Six tumors were located in the hypothalamic-chiasmatic-third ventricular region , two tumor involved the bilateral temporal lobe , and one tumor was associated with NF-I.One occurred in the basal ganglia region.Four tumors were solid masses , whereas the other three showed cystic components.Six tumors were hypointense and one was isointense on T 1-weighted image.Five tumors were hyperintense and three were isointense on T 2-weighted image.Four tumors were hypointense , one was iso-hypointense and one was isointense on DWI.After contrast administration , four tumors enhanced homogenously and three tumors enhanced heterogeneously , with intratumoral irregular hypointense region in two tumors and rim enhancement in one tumor.Cerebrospinal fluid ( CSF ) dissemination, hydrocephalus and peritumor edema were observed in 2, 4 and 1 of cases, respectively.Proton magnetic resonance spectrum of two PMA showed elevated Cho /Cr ratios and decreased NAA/Cr ratios.Conclusions The imaging features of pilomyxoid astrocytoma include common origination from the midline of the neuroaxis in younger children about 2-3 years old.The CSF dissemination is common.The presence of hemorrhage and peritumor edema is not common.
