Objective To evaluate the association between maternal thyroid diseases in the first trimester of pregnancy and obstetric complications.Methods A total of 2 517 pregnant women from 10 hospitals in Shenyang during the first 12 weeks of gestation were enrolled in this study.All sera obtained from pregnant women were measured for thyroid-stimulating hormone (TSH),free thyroxine ( FT4 ),and thyroid peroxidase antibody (TPOAb).Collected items include obstetric outcomes and complications.Results Serum TSH above 2.5 mlU/L during the first trimester of pregnancy increased the rate of spontaneous abortion ( 8.69% vs 6.38%,P =0.048 ),even if subclinical hypothyroidism (9.50% vs 6.38%,P =0.009).TSH above the gestational special reference range,passive smoking,and over 30 years were independent factors for increasing the rate of spontaneous abortion.Hyperthyroidism and hypothyroidism with drug treatment to maintain normal thyroid function during pregnancy reduced the incidence of spontaneous abortion.Increased or decreased levels of serum TSH and TPOAb(+) were not related with other obstetric complications.Conclusion Serum TSH above the gestational special reference range during the first trimester of pregnancy is a risk factor of spontaneous abortion; maintaining TSH within the normal range by treating hyperthyroidism or hypothyroidism may reduce spontaneous abortion rate.

Objective To analyze the timing and frequency of spontaneous gasping during cardiopulmonary resuscitation in a rat model,and evaluate its value bearing some relation to duration of cardiac arrest (CA ) in predicting the severity of post-resuscitation myocardial dysfunction.Methods Twenty-seven healthy Sprague-Dawley rats were randomly (random number)divided into 3 groups according to different durations of CA:CA 4 min (n=9),CA 6 min (n=9)and CA 8 min (n=9).CA of rats was electrically induced and untreated for 4,6 or 8 min respectively in the corresponding groups,and then cardiopulmonary resuscitation (CPR)was initiated and continued for 8 min in all animals.The emergence timing and frequency of spontaneous gasping during cardiopulmonary resuscitation and resuscitation outcomes were documented.Myocardial function such as cardiac output,ejection fraction and Tei index was measured by echocardiography prior to CA and at 1 h,2 h and 4 h post-resuscitation.Results The earliest appearance of gasping with highest frequency was observed in the CA 4 min group during CPR.Gasping appeared later with decreased frequency observed following longer duration of CA.There were statistically significant differences in the timing and frequency of gasping among the 3 groups.In the CA 4 min group with frequent gasping,all animals were successfully resuscitated with 8-min CPR with the least number of defibrillation,which was significantly better than that in the CA 8 min group.During the evaluation of post-resuscitation myocardial function,cardiac output,ejection fraction and myocardial work index (Tei index) were better in the CA 4 min group with frequent gasping,worse in the CA 6 min group and worst in the CA 8 min group, showing statistically significant differences in cardiac function among the 3 groups. Conclusions The spontaneous gasping appeared sooner with higher frequency during cardiopulmonary resuscitation indicated shorter duration of CA,and predicted better success of resuscitation and post-resuscitation myocardial function.

Background and purpose: Radiation therapy is still the most primary treatment of brain metastases, and prognosis is affected by many factors. The aim of this study was to identify the prognostic factors and to establish a prognostic index model in patients with brain metastases after whole-brain radiotherapy (WBRT). Methods: We reviewed the clinical date of 140 patients with brain metastases radiotherapy in our hospital from Jan. 2008 to Jul. 2011. The signiifcance of prognostic variables in the survival was resulted from both univariate analysis and multivariate analysis. The prognostic index (PI) was established based on Cox regression analysis and subgrouping values. It was assessed whether recursive partitioning analysis classes (RPA), basic score for brain metastases (BS-BM) and the graded prognostic assessment index (GPA) were related to prognosis. Results:The median survival time was 222 days. The univariate analysis showed that the independent prognostic factors were KPS performance status, number of brain metastases, presence of extracranial metastases, primary tumor status, radiation dose, hemoglobin. The multivariate analysis showed that KPS performance status (P=0.002, Wald=9.700), presence of extracranial metastases (P=0.018, Wald=5.604) and primary tumor status (P=0.001, Wald=10.212) were signiifcantly correlated with overall survival. RPA, BS-BM and GPA were closely related to their prognosis by Log-rank test. In predicting 3 months and 6 months of survival for patients, PI was better than other modes. Conclusion:Our data suggest that the 3 indexes RPA,BS-BM and GPA are valid prognostic index models, but PI model is better.

The prognosis of patients with brain metastases from non-small cell lung cance (NSCLC) is dismal,and whole brain radiation therapy(WBRT) cannot simultaneously control the extracranial lesions.Study results of Tyrosine kinase inhibitor(TKI) for brain metastases in patients with lung cancer are encouraging,and treatment efficacy is related to EGFR mutation status.The sensitizing theoretical foundation exists in utilizing erlotinib combined with WBRT for the treatment in brain metastases patients with lung cancer.Currently,a small clinical trial data shows that erlotinib combined with WBRT has better efficacy compared to erlotinib alone,and the toxicity can be tolerated.
