Objective To compare the different features of contrast enhanced ultrasound(CEUS) and CT angiography (CTA) in abdominal aortic remodeling after thoracic endovascular aortic repair (TEVAR)of DeBakey type Ⅲ aortic dissection(AD),and to investigate the application value of CEUS in the follow-up of DeBakey type Ⅲ AD after TEVAR.Methods CEUS was performed in 28 patients with DeBakey type Ⅲ AD after TEVAR,in which 8 cases type Ⅲ a (simple type) were not involved of abdominal aorta,20 cases Ⅲ b(complex type) were involved in the abdominal aorta,all patients were performed CTA examination of aorta.The functional and morphological changes of abdominal aortic remodeling were observed by two methods in DeBakey type Ⅲ AD after TEVAR.Results There was no new rupture of the abdominal aorta in 8 cases type Ⅲ a AD,but 20 cases of type Ⅲ b AD showed the situation of ruptures,thrombosis,trues and falses lumen after 3 months of follow-up.CEUS was less than CTA in detecting the number of ruptures (P＜0.05),CEUS and CTA results were similar in the measurement of true and false lumen diameter (P＞0.05),but CEUS clearly showed the hemodynamic characteristics of abdominal aortic intimal tear,the size and position of rupture,moving blood flow of rupture,and true or false lumen,which provided more accurate data for the long term abdominal aortic remodeling of DeBakey type Ⅲ AD after TEVAR.Conclusions CEUS and aortic CTA can play a complementary role in DeBakey type Ⅲ AD after TEVAR of long-term follow-up,it is worth promoting.

To investigate the electrophysiologic characteristics of f-wave amplitude and to evaluate its role in development and persistence of chronic atrial fibrillation (AF) associated with rheumatic heart disease (RHD). Methods: Epicardial mapping was performed in 44 patients with chronic AF of RHD who underwent heart valve surgery. Ten patients with supraventricular tachycardia served as the control group. Results:The f-wave amplitude of left atrium (LA) and middle and low LA posterior regions were significantly lower than those of the control group. The f-wave amplitudes of the upper, middle and low sections in LA posterior region were significantly lower than those in right atrium (RA) (P<0.05). The f-wave amplitudes were compared before and after electrocardioversion in 14 patients with chronic AF. The mean atrial electrogram amplitude during sinus rhythm was significantly higher than that during AF (P<0.01).The f-wave amplitude in left appendage was higher than that in LA posterior region (the upper,middle and the lower part),P<0.05.The f-wave amplitude in the upper section of LA was significantly higher than that in the middle section. The f-wave amplitude in AF group was not correlated to the diameter or volume of both atria. Conclusion: There are amplitudes differences between the upper, middle and lower LA,suggesting that the middle and lower sections of LA posterior wall may be the region producing anisotropy and reentrant circle.

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.

BACKGROUND: Salvia miltiorrhiza is widely used to treat angina cordis, ischemic stroke and other ischemic cardiovascular diseases. However, the effects of Salvia miltiorrhiza on ovariectomized rats remain unclear.OBJECTIVE: To observe the effects of Salvia miltiorrhiza on the body mass, food intake, and levels of blood lipids and malondialdehyde (MDA) in ovariectomized rats.DESIGN: A completely randomized and controlled experiment.SETTING: Institute of Physiology and Psychology, School of Basic Medical Sciences, Lanzhou University.MATERIALS: The experiment was performed in the Key Laboratory of Pre-clinical Study for New Drugs of Gansu Province and the laboratory of Institute of Physiology and Psychology, School of Basic Medical Sciences, Lanzhou University from November 2005 to December 2006. Twenty-four healthy female SD rats of 3 months old and (220±2) g were selected. Salvia miltiorrhiza water decoction (equal to 1 g/mL crude drug) was identified and extracted by Drug Control Institute of Gansu Province; MDA kit was purchased from Nanjing Jiancheng Institute of Bioengineering.METHODS: ①The rats were randomly divided into three groups with 8 rats in each group: sham-operated group,ovariectomized group and Salvia miltiorrhiza group. The rats were underwent a bilateral ovariectomy except those in the sham-operated group, which were subjected to a removal of bilateral fat as much as ovariectomized group with the ovaries remained. Rats in sham-operated group and ovariectomized group freely drank water; rats in Salvia miltiorrhiza group freely took 1% water extracts from Salvia miltiorrhiza postoperatively, and the concentration of Salvia miltiorrhiza gradually increased to 12% on the eighth day, which was lasted until the end of the experiment (55 days). ②The food intake of rats in each group was monitored daily, and the body mass was measured every five days. At the end of the experiment, femoral artery blood samples of rats were collected to determine the levels of blood lipids. At the same time,MDA was measured according to the kit.MAIN OUTCOME MEASURES: The body mass, food intake, levels of blood lipids and malondialdehyde in each group.RESULTS: Twenty-four rats all entered the result analysis. ①The body mass of rats in 3 groups was nearly the same before operation (P ＞ 0.05). While the body mass in ovariectomized group on the postoperatively 10th, 20th, 25th, and 55th days was significantly higher than those in sham-operated group (P ＜ 0.01). The body mass in Salvia miltiorrhiza group on the postoperatively 20th, 25th, and 55th days was significantly lower than those in ovariectomized group (P ＜0.05-0.01). ②The food intake in ovariectomized group on the postoperatively 15th, 40th, and 55th days was significantly higher than those in sham-operated group (P ＜ 0.05-0.01), and that in Salvia miltiorrhiza group was significantly lower than those in ovariectomized group at those 3 time points (P ＜ 0.05-0.01). ③At the end of the experiment, the levels of total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride in ovariectomized group were significantly higher than those in sham-operated group (P ＜ 0.05-0.01). The levels of triglyceride and MDA in Salvia miltiorrhiza group were significantly lower than those in ovariectomized group (P＜0.01, 0.05).CONCLUSION: Salvia miltiorrhiza can significantly reduce the body mass and levels of triglyceride and MDA in ovariectomized rats.

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.
