Objective: To construct lentivirus vectors carrying alphastatin gene, test its secretion expression in human umbilical vein endothelia cells (HUVECs) and observe its effects on growth, migration and tube formation of HUVECs. Methods: We constructed recombinant lentivirus vectors of NT4-alphastatin fusion gene containing neurotrophin-4 signal peptide, pro-region sequences and alphastatin, then transfected the recombinant lentivirus vectors into HUVECs to obtain secretory protein alphastatin and test its anti-angiogenic activities in vitro. Results: Our data showed that recombinant self-inactivating lentivirus vectors of NT4-alphastatin were successfully constructed, and stable NT4-alphastatin transduced HUVECs were capable of sustainably secreting alphastatin which significantly suppressed HUVECs migration and differentiation but not VEGF-induced proliferation. Conclusion: This report represents the first time on the use of lentivirus-based vectors to deliver alphastatin, the endogenous angiogenesis inhibitor, and reveals the potential utility of anti-angiogenic gene therapy with lentivirus vectors for treating cancer.

To study the influence of foreign plasmid DNA on spleen metabolism in immune-stimulated mice via the gastrointestinal tract. Mice were oral administered by pipette with 200?g of plasmid pcDNA3 and spleen were isolated at 4h and 18h after oral administration. Total RNA were extracted from spleen and spleen gene expression profile of Balb/c mice was analyzed by using Affymetrix oligonucleotide genechip after oral plasmid pcDNA3 administration. Functional cluster analysis was conducted by Genmapp and MAPPFinder software. By functional cluster analyzing the genes which were up-regulated more than twofolds, Genmapp results showed that plenty of metabolic pathway were induced in spleen after oral administration of plasmid pcDNA3. These metabolic process included purine metabolism, pyrimidine metabolism, protein synthesis, cholesterol synthesis, fatty acid synthesis, Glycolysis, TCA cycle and mitochondria oxidative phosphorylation pathway. The similar results also took place at 18h after oral administration. The result indicated that foreign plasmid DNA can modulate metabolism process in spleen of mice via the gastrointestinal tract, and may help understand the mechanism of action of foreign plasmid DNA uptaked via the gastrointestinal tract.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

Background and purpose: The protein tyrosine kinase-7 (PTK7) gene may be related to the occurrence and progression of many tumors. This study was aimed to explore the expression of PTK7 in ovarian serous tumors and its relationship with clinical stage, histological grade, metastasis and prognosis indicators linkages, and analyze the diagnostic and prognostic value of PTK7 in ovarian serous tumors. Methods:Expressions of PTK7 in 3 ovarian cell lines (HO8910, SKOV3, A2780), 14 cases of normal fallopian tube epithelium, 6 cases of benign serous ovarian tumors, 51 cases of borderline serous ovarian tumors and in 97 cases of ovarian serous carcinoma were detected by immunohistochemical EliVision two-step method. Statistical analysis of the relationship between the expression of PTK7 and the pathological indicators was performed byχ2 test, Fisher exact test and Kaplan-Meier method. Results:PTK7 was negatively expressed in HO8910 and A2780, but weakly positively expressed in SKOV3. The positive rates of PTK7 in normal fallopian tube epithelium, benign serous ovarian tumors, borderline serous ovarian tumors and serous ovarian cancer were 92.86%(13/14), 83.33%(5/6), 45.10%(23/51), and 28.87%(28/97), respectively. The expression of PTK7 had no difference between normal fallopian tube epithelium and benign serous tumors, benign serous tumors and serous borderline tumors (P=0.521, P=0.102). The PTK7 expression showed signiifcant differences in serous ovarian carcinoma compared with those in normal epithelium, benign serous tumors and borderline serous tumors (P=0.000, P=0.012, P=0.048). Expression of PTK7 in borderline serous ovarian tumors was signiifcantly with clinical stage, metastasis (lymph node and/or peritoneum metastasis) (P=0.038, P=0.038), rather than its location, age (P=0.088, P=0.896). Expression of PTK7 in ovarian serous carcinoma had a signiifcant relation with its clinical stage, WHO grade, MDACC grade (P=0.011, P=0.004, P=0.000), rather than its location, metastasis, tumor diameter and age (P=0.326, P=0.524, P=0.588, P=0.584). The survival rate of PTK7 positive group in ovarian serous carcinoma was signiifcantly higher than that in the negative control group (P=0.017). Conclusion:The expressions of PTK7 in normal ovarian epithelium, benign serous ovarian tumors, borderline serous ovarian tumors and epithelial serous carcinoma show a gradual downward trend. The expression of PTK7 in ovarian serous tumors has a positive correlation with late clinical stage, high histological grade and poor prognosis. PTK7 can be a new indicator of clinical diagnosis and prognosis in ovarian serous tumors.

OBJECTIVETo explore the anatomical features and measure the width of the coronal sulcus of the penis.

METHODSWe observed the coronal sulcus of the penis in 269 males aged 19 -66 (mean 28) years. Among them, 137 had redundant prepuce, 11 had phimosis, 90 were normal men, and 30 had been circumcised for redundant prepuce and 1 for phimosis. The width of the sulcus was measured with the vernier caliper at the 12 o'clock position, i. e. , the middle point of the dorsal. The results were compared among different groups.

RESULTSThe mucosa of the sulcus was relatively flat, smooth and not so active. Generally, the anterior line of the coronal sulcus was indistinct, whereas the posterior line was clear and easy to be identified. The widths of the coronal sulcus were (4.32 +/- 3.44), (4.06 +/- 2.68) and (4.22 +/- 3.06) mm in the redundant prepuce, phimosis and normal groups, with no statistically significant differences among the three (P > 0.05).

CONCLUSIONEnough attention should be paid to the width of the coronal sulcus of the penis in clinical practice. The posterior line of the coronal sulcus should be chosen as the positioning standard for inner incision in circumcision.

OBJECTIVETo explore the effect of puerarin in improving the insulin resistance (IR) and its closely related abnormal lipid and fibrinolytic activity in patients with coronary heart disease (CHD).

METHODSSeventy-six patients with CHD were randomly divided into two groups, 40 in the puerarin group and 36 in the routine treated group. Puerarin 500 mg was given to the former in addition to routine therapy by adding to 250 ml of normal saline for intravenous dripping once a day with a therapeutic course of 3 weeks. The changes of fasting blood glucose (FBG), fasting plasma insulin (FINS), plasma total cholesterol (TC), triglyceride (TG), low and high density lipoprotein cholesterol (LDL-C & HDL-C) and plasminogen activator inhibitor-1 (PAI-1) activity were measured before and after treatment, and the insulin sensitivity index (ISI) calculated. At the same time, tissue plasminogen activator (tPA) activity before and during venous occlusion test (VOT) was tested. Besides, 30 healthy subjects were taken as control.

RESULTSIn CHD patients, FINS, TC, TG, LDL-C and PAI-1 levels were higher and ISI, HDL-C and tPA before and during VOT were lower than those in the healthy controls. FINS and ISI correlated well with lipids and fibrinolytic abnormality. After puerarin treatment, FINS level lowered and ISI increased significantly (P < 0.01), while comparing with the routine group, TC, TG, LDL-C and PAI-1 were lower but HDL-C and tPA activity before and during VOT were higher in the puerarin group (P < 0.05, P < 0.01). Correlation analysis showed that FINS was positively correlated with TC, TG, LDL-C and PAI-1 and negatively correlated with HDL-C, tPA before and during VOT; ISI was negatively correlated with TC, TG, LDL-C and PAI-1 and positively correlated with HDL-C and tPA before and during VOT in the puerarin group.

CONCLUSIONPuerarin could improve the IR, IR related lipid and fibrinolytic activity abnormality in CHD patients.
