With the emergence of new endocrine drugs and the development of research in resistance mechanisms,significant progress has been achieved in the endocrine treatment of breast cancer in recent years. Fulvestrant,the combination of endocrine drugs and the combination of targeted therapy with endocrine therapy will be effective treatments for postmenopausal women with hormone receptor positive in advanced breast cancer.

Objective To study the relevance between the level of thyroid hormone and anti‐thyroid peroxidase antibody (TPOAb) during gestation period .Methods From November 2011 to May 2014 ,150 gravidas were chosen as objectives ,and were divided into 2 groups according TPOAb .The clinical feature ,level of thyroid hormone ,pregnancy outcome ,and complication of neo‐phyte between 2 groups were compared .Results In 150 gravidas ,44 were positive in TPOAb and 106 were negative .The age ,ges‐tational weeks and BMI between two groups had no statistical difference(P>0 .05) .At the early and middle pregnancy as well as at the late pregnancy ,the level of thyroid hormone between two groups had statistical difference(P<0 .05);In study group ,the level of thyroid hormone of early and middle pregnancy and that of late pregnancy had statistical difference(P<0 .05) .The rate of unde‐sirable gestational outcome and that of neophyte complication between two groups had statistical difference(P<0 .05) .Conclusion During gestation period ,the TPOAb was significant for the diagnosis of the sub‐clinical hypothyroidism ,as well for prognosis of gravidas .

Objective To analyze the correlation between the polymorphism of PTPN22 gene (R620W and R263Q sites)and pulmonary tuberculosis(TB)in Chinese Han population and to investigate the environmental factors associated with pulmonary TB. Methods A case-control study was conducted on 235 patients with pulmonary TB and 251 healthy subjects. The single nucleotide polymorphisms(SNP)of PTPN22 gene at R620W and R263Q sites were detected by the assay of polymerase chain reaction and re-striction fragment length polymorphism(PCR-RFLP). A questionnaire was designed to gather information about tuberculosis-associated environmental factors. Univariate and multivariate logistic analysis were con-ducted. Results Genotype frequencies of PTPN22 R620W(C1858T)SNP were 233(99. 15% ,CC),2 (0. 85% ,CT),0(0% ,TT)in patients with pulmonary TB and 240(95. 62% ,CC),11(4. 38% ,CT), 0(0% ,TT)in healthy subjects. There was a difference with the distribution of PTPN22 C1858T allele be-tween patients with pulmonary TB and healthy subjects[0. 43% vs 2. 19% ,P = 0. 01,odds ratio(OR)=0. 19,95% confidence interval(CI)= 0. 07-0. 35]. Genotype frequencies of PTPN22 R263Q(G788A) were 218(92. 77% ,GG),17(7. 31% ,GA),0(0% ,AA)in patients with pulmonary TB and 248 (98. 71% ,GG),3(1. 29% ,GA),0(0% ,AA)in healthy subjects. The frequencies of G788A allele in patients with pulmonary TB were higher than those in healthy subjects(3. 62% vs 0. 60% ,P﹤0. 01,OR=6. 03,95% CI=2. 12-18. 38). Conclusion The results of this study suggested that the R263Q GG geno-type of PTPN22 gene was associated with the susceptibility to TB in Chinese Han population.

Objective To study the value of the semiquantitative-parameter analysis of wash out index of time-intensity curve (Swash-out) in evaluating the therapeutic effect of neoadjuvant chemotherapy for locally advanced breast cancer (LABC).Methods Fifty-nine women with LABC underwent dynamic contrast enhancedt MRI examination before chemotherapy,after the 2nd cycle and the 4th cycle of chemotherapy.All patients were divided into major histological response group (MHR) and non-major histological response group (NMHR) according to the final pathologic response.Swash-out and the variancetrends of Swash-out before NAC,after the 2nd cycle of NAC and after the 4th cycle of NAC were compared in each group and between the two groups.According to the gold standard of Miller & Payne criterion,Receiver operating characteristic curve (ROC) analysis was performed to evaluate the predicting effect of Swash-out for NAC response,and to compare it with Semi-quantitative TIC curve indicators Smax (steepest slope) and PPE (peak percent enhancement).Results Fifty-nine patients of LABC patients were divided into a MHR group of 34 patients and a NMHR group of 25 patients.Swash before NAC of MHR group was-16.99 (-56.72-41.20),Swash-out after the 2nd cycle of NAC was 5.66(-69.45-53.08),Swash-out after 4th cycle of NAC was 15.95 (-7.80-54.23).Swash-out before NAC of NMHR group was-23.08 (-64.24-34.39),Swash-out after the 2nd cycle of NAC of NMHR group was-23.01 (-52.72-28.70),Swash-out after 4th cycle of NAC of NMHR group was-11.45 (-50.49-50.93).Swash-out variance rate of MHR group after the 2nd and the 4th cycle of NAC were-1.18 (-31.32-60.86) and 1.50 (-86.27-3.61),respectively.Swash-out variance rate of NMHR group after the 2nd and the 4th cycle of NAC were-0.28(-3.24-9.46) and 0.27 (-5.34-3.11),respectively.Swash-out was not significantly different between the two groups before NAC (Z =-0.97,P ＞0.05).Swash-out and Swash-out variance rate of MHR group after the 2nd cycle of NAC were significant higher than that of NMHR group (Z =-3.97 and-3.02,P ＜0.01).Swash-out and Swash-out variance rate of MHR group after the 4th cycle of NAC were significant higher than that of NMHR group (Z =-3.96 and-3.16,P ＜ 0.01).Area under curve (Az) after the 2nd and the 4th cycle of NAC were 0.805 and 0.804,respectively,and no significant difference was found between them (Z =0.019,P ＞0.05).Diagnostic cut-off points were-8.670 for the 2nd cycle of NAC and 4.105 for the 4th cycle of NAC.Diagnostic sensitivity was 79.42％,specificity was 76.00％ and Youden index was 0.554,for after the 2nd and the 4th cycle of NAC.Conclusion Swash-out of TIC curve before NAC cannot predict the response of NAC,Swash-out of TIC curve after the 2nd cycle of NAC and after the 4th cycle of NAC are efficient in predicting the response of NAC.
