The expressions of estrogen receptor (ER) α,ERβ1,and ERβ2 in thyroid carcinoma,thyroid adenoma,and adjacent normal thyroid tissue were determined by RT-PCR and immunohistochemistry,and the relationship of expression levels of three ERs and the main clinical pathologic parameters were evaluated.The result showed that ERα mRNA expression in papillary thyroid carcinoma(PTC) tissues was significantly higher than adjacent normal tissue,while,ERβ2 mRNA expression in PTC tissues was significantly lower than normal tissue ( P＜0.05 ).The positive expression of ERβ1 and ERβ2 in the thyroid carcinoma was related with the histological variant of carcinomas; the ERβ2 expressions were related with the lymph node metastasis and TNM staging of the carcinomas.These results suggest that the decreased ERβ2 expression may induce proliferation and carcinogenesis of thyroid follicular epithelial cells as well as progression of the carcinoma,and is a powerful prognostic indicator.

Objective To investigate the expression of signal-induced proliferation-associated gene 1 (SIPA1), Ezrin and E-cadherin (E-cad), and their relationship with clinical patterns in epithelial ovarian carcinoma.Methods Immunohistochemistry was used to detect the expression of SIPA1, Ezrin and E-cad in normal ovarian tissue, benign epithelial ovarian tumor, borderline epithelial ovarian tumor and epithelial ovarian carcinoma,respectively. Results The positive rate of SIPA1 expression was 44.2 % (23/52), 64.5 %(20/31), 93.3 % (28/30) and 100.0 % (15/15) in epithelial ovarian carcinoma, borderline epithelial ovarian tumor, benign epithelial ovarian tumor, and normal ovarian tissue, respectively, and there was a statistical difference (χ2 = 29.159, P= 0.000). The corresponding rates were 57.7 % (30/52), 61.3 % (19/31), 90.0 %(27/30) and 93.3 % (14/15) for the positive rate of Ezrin expression (χ2= 14.555, P= 0.002), as well as for 23.1 % (12/52), 58.1 % (18/31), 86.7 % (26/30) and 0 (0/15) for the positive rate of E-cad expression, respectively (χ2= 45.731, P= 0.000). In patients with epithelial ovarian carcinoma, the expression of SIPA1 was correlated with tumor differentiation (χ2=3.895, P=0.048), but not with histological type and clinical stage (all P>0.05). The expression of Ezrin was not correlated with histological type, tumor differentiation and clinical stage (all P>0.05). There was a positive correlation between expression of E-cad and SIPA1, Ezrin in epithelial ovarian carcinoma, respectively (r= 0.339, P= 0.014; r= 0.284, P= 0.041), but no correlation between the expression of SIPA1 and Ezrin (r= 0.214, P= 0.128). Conclusions SIPA1, Ezrin and E-cad play important roles in the occurrence and development of epithelial ovarian carcinoma. They cooperate in the progression and their combined detection can better evaluate the prognosis of epithelial ovarian carcinoma.

Objective To evaluate the acute and long-term results of stenting for left main coronary artery (LMCA) bifurcation lesions. Methods Forty consecutive patients with LMCA bifurcation lesion and normal left ventricular function were included. Sirolimus-eluting stents were performed in all patients. Results (1)The average diameter of LMCA was (0.81?0.48)mm before stenting and increased to (3.53?0.22)mm after stenting.(2)The procedural success rate was 100.0%. In-hospital events including stent thrombosis,Q-wave myocardial infarction,and emergency bypass surgery did not occur in any patients,and non-Q-wave MI in one patient (2.5%).(3)Clinical follow-up was obtained in all patients at (8.43?3.24) months. There were no death and no myocardial infarction during follow-up. The major adverse cardis events rate was 20.0%.(4)The angiographic follow-up rate was 67.5% (27 of the 40 eligible patients),and the restenosis rate was 18.5% (parent vessel only 11.1%,side branch only 3.7%,and both 3.7%).(5)Different type of operation had no influence on restenosis rate during angiographic follow-up. Conclusion Sirolimus-eluting stent implantation for LMCA bifurcation stenosis appears safe and effective with regard to acute and midterm complications.

OBJECTIVETo evaluate clinical significance of waist soft tissue tension detection in treating chronic nonspecific low back pain.

METHODSFrom August 2011 to March 2012,60 patients with chronic nonspecific low back pain were divided into two groups (sliver needle group and TCM fumigation group) according to propotion of 1:1. In sliver needle group, there were 17 males and 13 females aged from 28 to 55 years old with an average age of (45.70 +/- 4.15), treated with sliver needle; In TCM fumigation group,there were 19 males and 11 females aged from 27 to 55 years old with an average age of (43.03 +/- 5.86), treated with TCM fumigation. Changes of force-displacement distance (FDD), specific absorption rate (S) of two groups were observed before treatment, 1 week and 3 months after treatment respectively, VAS scoring and Roland-Morris disability questionnaire (RMDQ) were used to access clinical effects.

RESULTS(1) VAS score of silver needle group was 4.77 +/- 0.78, 1.99 +/- 1.08 and 2.55 +/- 0.94, respectively before treatment, at 1 week and 3 months after treatment,while VAS score in TCM fumigation group were 4.43 +/- 0.61, 2.48 +/- 0.71 and 3.05 +/- 0.86, respectively. VAS score of two groups after treatment were sigificant decrease than that of before treatment (P < 0.05). There was no sigificant differences between two groups before treatment, but sliver needle group performed well in analgesia than TCM fumigation group, and had obvious differences (P < 0.05). RMDQ score of silver needle group was 13.63 +/- 1.96, 5.87 +/- 2.33 and 6.53 +/- 2.89, respectively before treatment, at 1 week and 3 months after treatment, while RMDQ score in TCM fumigation group were 13.40 +/- 2.01, 6.90 +/- 2.31, 9.23 +/- 2.87, respectively. There was no significant differences between two groups before treatment and 1 week after treatment (P > 0.05), and had obvious differences between two groups at 3 months after treatment (P < 0.01). Both groups could obvious improve dysfunction caused by chronic low back pain, and curative effect of sliver needle groups was more endurable. (2) Following-up at 3 months after treatment, FDD of multifidus, erector spinae of effected side and multifidus of healthy in sliver needle group were obvious increased (P < 0.05); In TCM fumigation group, FDD of multifidus and erector spinae on both side were increased at 1 week after treatment (P < 0.05), but had no significant meaning at 3 months after treatment on health side (P>0.05). There was no significant meaning before treatment (P > 0.05), FDD of multifidus, erector spinae of effected side in sliver needle group were obvious increased at 1 week after treatment (P < 0.05); but no obvious meaning on health side. FDD of both side in sliver needle group were obvious increased at 3 months after treatment. (3) There was correlation among differences of FDD in multifidus and erector spinae, VAS score and differences of RMDQ, and Spearman correlation coefficient R was 0.517, 0.811, 0.746 and 0.625; There was correlation between items of soft tissue tension and sympotoms, function and life quality. Conclusion:Soft tissue tension detection can effectively manifest degree of pain and dysfunction of low back, and improve objectivity of therapeutic evaluation for chronic low back pain.

OBJECTIVETo investigate the risk factors for the occurrence of patent ductus arteriosus (PDA) and to provide a clinical basis for reducing the occurrence of PDA in early preterm infants.

METHODSA total of 136 early preterm infants (gestational age≤32 weeks) who were hospitalized between January 2013 and December 2014 and diagnosed with hemodynamicalhy significant PDA (hs-PDA) were enrolled as the case group. Based on the matched case-control principle, 136 early preterm infants without hs-PDA were selected among those who were hospitalized within the same period at a ratio of 1:1 and enrolled as the control group. The two groups were matched for sex and gestational age. The basic information of neonates and maternal conditions during the pregnancy and perinatal periods were collected. Logistic regression analysis was performed to identify the risk factors for the development of PDA.

RESULTSUnivariate analysis showed that neonatal infectious diseases, neonatal respiratory distress syndrome, decreased platelet count within 24 hours after birth, and low birth weight were associated with the development of hs-PDA (P<0.05). Multivariate conditional logistic regression analysis revealed that neonatal infectious diseases (OR=2.368) and decreased platelet count within 24 hours after birth (OR=0.996) were independent risk factors for hs-PDA.

CONCLUSIONSNeonatal infectious diseases and decreased platelet count within 24 hours after birth increase the risk of hs-PDA in early preterm infants.
