Objective To study the expression and clinical significance of CD34 and smooth muscle actin (SMA) in stroma of breast tissues and lesions. Methods Seventy cases of breast tissues and lesions, including 20 fibroadenomas, 10 sclerosing adnoses, 30 invasive ductal carcinomas and 10 invasive lobular carcinomas were investigated, and 10 normal breast tissues were served as controls. Immunohistochemical staining was applied to compare the distribution of CD34+ fibrocytes and SMA-reactive myofibroblasts. Results The stroma of normal breast tissue contained CD34+ fibrocytes, whereas SMA-reactive myofibroblasts were absent (100% for both). All benign breast lesions exhibited astromal CD34+ fibrobytes, and fibroadenomas showed SMA-reactive myofibroblasts as well. In invasive ductal and lobular carcinoma the stroma was devoid of CD34+ fibrocytes, but a varying number of stromal SMA-reactive myofibroblasts were detectable (100%). Conclusion In breast carcer, immunohistochemical staining used in detecting expressions of CD34 and SMA is helpful in distinguishing benign lesions from malignancies.

In order to study the spectral reflectance differences of Glycyrrhizae Radix under different growth conditions and lay the foundation for quantitative monitoring of Glycyrrhizae Radix remote sensing images, spectra of Glycyrrhiza species under different growth period and different varieties and different regions were measured by a portable spectrometer. The results showed that the reflectivity of annual G. uralensis was obviously higher than that of the two years plant in the visible light band own to the contents of crown layer chlorophyll. The reflectivity of two years G. pallidiflora was higher than that of G. uralensis in the near infrared band own to the leaf area index and the content of leaf water. The red edge spectrum of annual plant fluctuated largely than that of two years plant due to vegetation coverage and leaf area index. G. pallidiflora grew well than G. uralensis. Under different regions of the Glycyrrhiza species, spectral data analysis showed that within a certain range, the average annual precipitation and average annual evaporation were the major factors to affect the differences of Glycyrrhiza species spectral data under different regions owe to the leaf water content, the higher leaf water content, the lower spectral reflectance. The principal component analysis and continuum-removed method of the spectral data under different regions found that, within a certain range, the average annual precipitation and average annual evaporation were the major factors caused by the differences of Glycyrrhiza species spectral data under the different regions, Glycyrrhiza species spectral similarity related to the spatial distance.

Objective To compare the outcomes of in-vitro maturation (IVM) and in-vitro fertilization (IVF) after early follicular phase gonadotropin-releasing hormone agonist (GnRH-a)down-regulation in infertile patients with polycystic ovary syndrome (PCOS).Methods From July 2010 to December 2012,72 infertile patients with PCOS undergoing assisted reproductive technology treatment in the Affiliated First Hospital of Wenzhou Medical University were enrolled in this study.The patients were divided into 2 groups,which were patients with early follieular phase down-regulation IVM (36 cases) at IVM group and early follicular phase down-regulation long protocol IVF (36 cases) at IVF group.The laboratory parameters and clinical outcomes were compared between two groups.Results (1) Lab parameters:a total of 442 oocytes were retrieved in group IVM,and 560 were in group IVF.The rate of mature oocytes of 83.8％ (469/560) and high-quality embryos of 70.9％ (212/299) at group IVF were significantly higher than that of group IVM [54.1％ (239/442) and 50.7％ (73/144),retrospectively,P ＜0.01].In group IVM,the average duration of gonadotropin (Gn) was (2.8 ± 1.5) days and the average dosage of Gn was (285 ± 169) U,which were significantly lower than (11.0 ± 1.0) days and (1499 ±165) U in group IVF (P ＜0.01).The mean number of oocytes retrieved 12.8 ± 2.5,fertilization rate of 64.8％ (155/239),and implantation rate of 31％ (23/74) in group IVM and 15.6 ±3.1,65.5％ (307/469),31％ (23/74) in group IVF,which did not reach statistical difference (P ＞0.05).(2) Clinical outcomes:the clinical pregnancy rate (17/31,55％) of IVF group was not significantly higher than that 44％ (14/32) at IVM group (P ＞ 0.05).The abortion rate was 1/17 at Group IVF and 1/14 in group IVM,which did not show statistical difference.Women at IVM group has no ovarian hyper-stimulation syndrome (OHSS) cycle,group IVF has 31％ (11/36) cycles presented moderate and severe OHSS.Conclusions Infertile patients with PCOS undergoing IVM and IVF treatment after early follicular phase GnRH-a down-regulation can get satisfactory laboratory and clinical outcome.In addition to short treatment cycle,IVM can also avoid the occurrence of OHSS completely,but it has a rising trend in the abortion rate.IVF has a high incidence of OHSS,meanwhile,it increases the dosage of gonadotropins.

Objective To study the expression of KAI1 and CD40 in gastric cancer and their correlation with clinicopathologic features and prognosis.Methods The expression of KAI1 and CD40 of 64 gastric cancer tissues was examinated by S-P immunohistochemieal methods.Results The overall positive rate of KAI1 was 22% in gastric cancer.Expression of KAI1 was positively related to the degree of tumor differentiation,it was negatively related to invasion depth and lymph node metastasis and the tumor clinical stage.The 5-year survival rate of cases with positive expression of KAII was significantly higher than that of cases with negative expression(X~2=42.426,P=0.000).The expression rate of CD40 in gastric cancer tissue was 34%.The expression of CD40 was significantly correlated with metastasis and clinical stage of gastric cancer.The 5-year survival rate of cases with positive expression of CD40 was significantly lower than that of cases with negative expression(X~2=4.841,P=0.028).There is no relationship between KAI1 and CD40 expression in gastric cancer.Conclusion KAI1 is associated with gastric cancer differentiation,invasion and metastasis.CD40 status helps to evaluate metastasis,and predict prognosis of gastric cancer.

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.

METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.

RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.

CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.

Objective The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hardening agent localization.Methods From December 2010 to January 2012,27 patients with 29 solitary pulmonary nodules who had undergone CT-guided hardening agent localization and video-assisted thoracoscopic surgery (VATS) were studied.Results All cases were underwent CT-guided hardening agent localization successfully,and no patient had serious complication that required any intervention.The diameter of nodules ranged from 3 to 21 mm as measured by CT[mean (11.27 ± 6.32) mm].The distance between the center of nodule and visceral pleural ranged from 4 to 38 mm[mean (14.45 ± 4.32) mm].Conversion from VATS to thoracotomies was not necessary during the diagnostic resection procedure nodules.29 solitary pulmonary nodules underwent thoracoscopic wedge resection,and no intra-or postoperative mortality or morbidity was recorded.Conclusion CT-guided hardening agent localization before video-assisted thoracoscopic solitary pulmonary nodule resection is a safe and effective procedure for accurate diagnosis and resection of indeterminate solitary pulmonary nodules.

Objective To compare the laboratory and clinical results between unstimulated in vitro maturation (IVM) and IVM converted from in vitro fertilization (IVF) in polycystic ovarian syndrome (PCOS) and non-PCOS patients.Methods We divided 591 IVM cycles in the First Affiliated Hospital of Wenzhou Medical Univesity from Jan.2008 to Dec.2013 into 4 groups:group A1B1,PCOS patients underwent unstimulated IVM protocol,240 cycles; group A1B2,PCOS patients underwent IVM converted from conventional stimulated IVF protocol,153 cycles; group A2B1,non-PCOS patients underwent unstimutlated IVM protocol,103 cycles; group A2B2,non-PCOS patient underwent IVM converted from conventional stimulated IVF protocol,95 cycles.Multiple linear regression method and binary logistic regression method were used to assess the influence of PCOS and protocols for IVM on laboratory and clinical outcomes.Results The mean number of oocytes retrieved was positively related with PCOS [partial regression coefficient (B)=3.37,P＜0.01].The maturation rate of oocytes was positively related with hCG-prime prior to oocyte aspiration (B=0.05,P=0.010).High-quality embryo rate was positively related with PCOS and IVM converted from IVF (B=0.08,P=0.010; B=0.09,P=0.001),as well as implantation rate related with them (B=0.07,P=0.010; B=0.10,P＜0.01).PCOS and IVM converted from IVF improved hCG positive (hCG＞10 U/L) rate (OR=1.636,95％CI:1.113-2.204,P＜0.05; OR=1.861,95％CI:1.307-2.649,P＜0.05) and the clinical pregnancy rate (OR=1.507,95％CI:1.041-2.240,P＜0.05; OR=1.881,95％CI:1.312-2.696,P＜0.05).IVM converted from IVF protocol decreased the spontaneous abortion rate (OR=0.490,95％CI:0.245-0.978,P＜0.05).Multiple gestation rate and ectopic pregnancy rate were not affected by PCOS condition and protocol used (P＞0.05).Conclusions PCOS and IVM converted from IVF protocol improved the high-quality embryo rate,implantation rate,hCG positive rate and clinical pregnancy rate.IVM converted from IVF protocol reduced the spontaneous abortion rate.PCOS patients may be more suitable for the IVM treatment.No matter PCOS or non-PCOS patients,IVM converted from IVF protocol had better pregnancy outcome than that of unstimulated cycle.

Objective To analysis the incidence and management of monozygotic twin (MZT) conceived by assisted reproductive techniques (ART). Methods A retrospective analysis of clinical pregnancies and MZT that resulted from ART was performed in Reproductive Medical Center,the First Affiliated Hospital,Wenzhou Medical University between January 2011 and January 2014. Results A total of 5 908 pregnancies were diagnosed: 2 012 twins, 157 high-order multiple pregnancy (HOMP), including 4 quadruplets. Overall, 51 MZT pregnancies were identified of them including 32 cases HOMP and 19 cases MZT. The incidence of MZT resulting from cleavage-stage embryo transfer was similar to blastocyst transfer (P=0.960). The percent of MZT resulting from in vitro fertilization [0.93% (28/3 022)], frozen-thawed embryo transfer [0.87% (13/1 502)] and intracytoplamic sperm injection [0.72% (10/1 384)] did not show statistical significance (P=0.794). The expectantly managed MZT was associated with a significantly greater likelihood of miscarriage [6/19 vs 5.11% (101/1 976)], and low birth weight infant [73.91% (17/23) vs 42.89% (1 453/3 388), P<0.01], when compared with dizygotic twin (DZT) did not undergo selective embryo reduction(SER). In monozygotic (MZ)-triplets with SER to 2 fetuses or to 1 fetus, there was no cases of preterm birth or low birth weight infant observed in MZ-triplets with SER to 1 fetus;when compared with MZ-triplets with SER to 2 fetuses, the low birth weight infant [56.00% (14/25), P=0.021] has statistical significance. The likelihood of the survival of two babies was lower in MZ-triplets with SER to 2 fetuses when compared with non-MZ triplets with SER to 2 fetuses [42.86%(9/21)vs 75.21%(91/121), P=0.003]. Conclusions The incidence of MZT pregnancies following ART is high. It plays a significant role in the occurrence of HOMP. MZT pregnancies are at an increased risk of adverse outcomes , it should transform to a single embryo thansfer (SET) program to reduce them incideuce. Reduction of MZT contained in multiple pregnancies appears to be a safe option.

Ulcerative colitis (UC) is a chronic inflammatory disease and its involvement area in colon is influenced by a complex network of gene interactions.We analyzed the weighted gene co-expression networks in microarray dataset from colonic mucosa of patients with UC and identified one gene co-expression module that was highly associated with the progression of involved area in UC colon (Pearson coefficient=0.81,P＜0.0001).In total,523 hub genes in this module were found to be involved in immune system process after enrichment analysis in Gene Ontology.By the STRING and Cytoscape analysis,we observed that interleukin-8 (IL-8) and matrix metalloproteinase-9 (MMP-9) were centered in the network of hub genes.We then detected the expression of IL-8 and MMP-9 in mucosa from left-sided colon of patients using quantitative PCR and immunofluorescence assay respectively.Both quantitative PCR and immunofluorescence assay revealed the expression levels of IL-8 and MMP-9 were significantly different among the healthy controls,left-sided colitis group and pancolitis group (P＜0.05).IL-8 and MMP-9 were detected with an enhanced expression in pancolitis as compared with left-sided colitis and healthy controls,respectively (P＜0.05).This study demonstrates that immune system process is indispensable in the progression of disease in colon,and identifies that IL-8 and MMP-9 play potential critical roles for the progression.
