Tenascin-C (TNC) is an extracellular matrix glycoprotein, which is usually highly expressed in embryonic tissues and tumor tissues, but is not expressed or just lowly expressed in mature tissues. TNC is involved in various complex signaling pathways during tumor metastasis, especially through modulating FAK, RhoA, Wnt and Notch pathways by interacting with syndecan-4, integrin α5β1, matrix metalloproteinases (MMPs) and vascular endothelial growth factor (VEGF). As a result, TNC affects epithelial mesenchymal transition, tumor cell adhesion, proliferation and angiogenesis, which eventually enhances the invasion and metastasis ability of many tumors. Further studies have demonstrated that TNC could be used as prognosis or metastasis marker of patients with malignant tumor.

Objective To establish a differently expressed genetic profile in placental tissues of pregnancy induced hypertension(PIH). Method The total RNAs were isolated from the tissues by Trizol and mRNA was purified by Midi Kit. The expression of 17 000 genes in placental tissues of 6 PIH and 5 normoten sive women were evaluated by cDNA array technique. Results Ninety-six differently expressed genes were identified in placental tissue of PIH compared with normal pregnancy cases. Seventy-eight genes were up-regulated and 18 were down-regulated. There were 6 unclassified genes, 8 unknown expressed sequence tag (EST) fragments and 3 cDNA fragments among these differently expressed genes. The differently expressed genes were involved in transcription and translation,cell differentiation,receptor,apoptosis,immune,metabolism and growth. Conclusion The cellular mechanism of PIH involves changes in genes expression in placental tissue. Microarray is a useful method to identify differently expressed genes in tissue.

OBJECTIVETo explore the clinical effect of Shugan Jieyu Capsules (SJC) on type III B prostatitis complicated by sexual dysfunction.

METHODSA total of 98 patients with type III B prostatitis complicated by sexual dysfunction were equally randomized to a control and a trial group, the former treated with the combination of biofeedback/electrical stimulation and the α-blocker Tamsulosin Hydrochloride, and the latter with oral SJC in addition, both for 8 weeks. Before and after treatment, the severity of the symptoms was determined with NIH-CPSI, the patients'sexual function evaluated with CIPE-5 and IIEF-5, and their anxiety, depression and other psychological problems assessed with Hamilton Anxiety Scale (HAMA) and Hamilton Depression Rating Scale ( HAMD). The results were subjected to statistical analysis and compared between the two groups.

RESULTSStatistically significant differences were found between the control and trial groups in the NIH-CPSI score (26.31 ± 7.91 vs 18.84 ± 6.63, P < 0.01), CIPE-5 premature ejaculation score (10. 41 ± 3.03 vs 14.37 ± 2.35, P < 0.05), IIEF-5 score (10.29 ± 3.97 vs 14.69 ± 4.19, P < 0.05), HAMA score (24.31 ± 1.78 vs 13.41 ± 4.21, P < 0.01), and HAMD score (25.24 ± 2.83 vs 14.49 ± 4.44, P < 0.01).

CONCLUSIONSJC can effectively relieve anxiety, depression and other psychological problems in type III B prostatitis patients with sexual dysfunction and improve their clinical symptoms as well.

Objective: Farnesyl pyrophosphate synthase (FPS) is the key enzyme in biosynthesis pathway of astragaloside IV. The purpose of the experiment was to provide the theory basis for selecting appropriate expression systems and regulating the content of astragaloside IV. Method: FPS gene coding sequence was cloned based on Astragalus membranaceus from Changbai Mountain. Synonymous codons usage of FPS gene was analyzed by EMBOSS and Codon W programs and compared with the genome of other seven plants, such as Zea mays and Artemisia apiacea, and E. coli. Results: FPS gene of A. membranaceus was bias toward the codon with A and T at the third codon position and there are 22 codons showing the significant differences between FPS gene of A. membranaceus and E. coli genome. Conclution: The codons need to be optimized to improve the expression level of FPS gene in E. coli.

OBJECTIVETo explore effects of Tongxinluo Capsule (TC) on platelet activating factor (PAF), vascular endothelial function, thrombolysis in myocardial infarction (TIMI) blood flow, and heart function in acute myocardial infarction (AMI) patients after delayed percutaneous coronary intervention (PCI).

METHODSTotally 80 AMI inpatients were recruited at Department of Cardiology, People's Hospital of Jiangxi Province, from Jan. 2008 to Sep.2013. Those in line with inclusion criteria were randomly assigned to TC treatment group and the conventional treatment group by random digit table, 40 in each group. Besides, another 40 healthy subjects from examinees at Outpatient Department were recruited as a healthy control group. PCI was performed after 1-week treatment. Then blood samples were collected, and then blood contents of CD62P, CD63, GP II b/III a, ET-1, NO, and plasma von Willebrand factor (vWF) levels were detected. Coronary TIMI blood flow and corrected TIMI frame count (CTFC) were determined during PCI. Meanwhile, noninvasive blood pressure (BP) and heart rate (HR) were recorded before and after PCI, and cardiac function measured. They were compared with the healty control group.

RESULTSCompared with the healthy control group, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 significantly increased, but NO significantly decreased in AMI patients (all P < 0.05). After 1-week intervention of TC, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, NO, and ET-1 significantly decreased (P < 0.05, P < 0.01). Compared with the conventional treatment group at the same time point, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 decreased more significantly in the TC group (P < 0.05, P < 0.01), increased NO levels were also more obviously seen (P < 0.01). The aforesaid parameters changed more obviously at day 30, as compared with those changes at week 1 (P < 0.05, P < 0.01). The TIMI blood flow grade and CTFC were more obviously improved after PCI in the two treatment groups. Better TIMI blood flow was seen in the TC group. TIMI level 3 blood flow rate was higher in the TC group than in the conventional treatment group with statistical difference (P < 0.05). The left ventricular ejective factor (LVEF) after PCI was obviously elevated in the TC group and the conventional treatment group (P < 0.01), and the improvement was more obviously seen in the TC group (P < 0.05). There were 6 cases of recurrent angina, 3 cases of ventricular tachycardial (VT)/ventricular fibrillation (VF), 6 cases of heart failure (HF), 1 case of cardiac sudden death in the conventional treatment group, with the total incidence of cardiovascular events being 40% (16/40). There were 2 cases of recurrent angina, 2 cases of VT/VF, 2 cases of HF, no cardiac sudden death in the TC treatment group, with the total incidence of cardiovascular events being 15% (6/40). There was statistical difference in the recurrent rate of cardiovascular events between the two groups (χ² = 2.27, P < 0.05).

CONCLUSIONTC not only could prevent coronary embolism of AMI patients after delayed PCI, attenuate vascular endothelial injury, but also could improve TIMI blood flow, and strengthen cardiac systolic function.

Objective:To investigate the mechanisms of genistein (GEN) affecting the chemosen- sitivity of human breast cancer cell line MDA-MB-453 to paclitaxel (PTX) in vitro. Method:HER2/neu- overexpressing breast cancer cells MDA-MB-453 were treated by GEN, PTX alone or combined in vitro. Cell cycle was measured by flow cytometry. The expression of HER2/neu protein was observed by immunocytochemistry and. Akt, p-Akt, cyclin B1 and CDK1 protein by Western blot. Results:Cell cycle of MDA-MB-453 cells was blocked at G1/S after treatment of GEN, while at G2/M after treatment with PTX alone. Both GEN and PTX did not change the expression of HER2/neu, total Akt and CDK1 in MDA-MB-453 cells, but GEN significantly decreased p-Akt and cyclin B1 level, and PTX obviously increased cyclinB1 level. GEN antagonized the effects of PTX on level of cyclin B1 protein and blockage of G2/M in MDA-MB-453 cells after treatment with GEN and PTX in combination. Conclusion:The antagonism effects of GEN on the increase of cyclin B1 and blockage of G2/M induced by PTX may be one of the mechanisms of GEN affecting the chemosensitivity of MDA-MB-453 cells to PYX.
