Journal of Third Military Medical University 1984;0(02):-
Objective To investigate the inhibitory effect of genistein on the invasion of ovarian carcinoma cell line SKOV 3 in vivo and in vitro. Methods The abilities of the genistein-treated SKOV 3 cells to invade through reconstituted matrigel in transwell chambers were investigated in vitro and the invasion effect in vivo was determined using the xenograft models of SKOV 3 in nude mice. Results The ability of the 20 ?mol/L genistein-treated cells to invade the reconstituted basement membrane was decreased significantly at 72 h. This inhibition was in a dose-dependent manner. Genistein at the dose of 40 ?mol/L had the strongest effect. The results in vivo suggested that the grade of invasion in control SKOV 3 cells was in a time-dependent manner and genistein-treated group could apparently inhibit the progress of invasion, localizing the tumor in invasion grade 0 or grade I, and decreasing the proportion of grades Ⅱ, Ⅲ, Ⅳ. Conclusion The results suggest that genistein has inhibitory effect on the invasion of human ovarian carcinoma cell lines SKOV 3 in vivo and in vitro.

Journal of Third Military Medical University 2003;0(16):-
Objective To investigate how genistein to inhibit the invasion of human ovarian serous papillary cystadenocarcinoma cell line SKOV3.Methods Millicell chamber and coculture method were used to establish chemotactic migration model in vitro to observe the effect of genistein on directional chemotactic migration movement of SKOV3 cells.The protein expressions of cell surface adhesion molecule CD44v6,matrix metalloproteinases and tissue inhibitor of metalloproteinases MMP-9/TIMP-1 and MMP-2/TIMP-2 were determined by using immunocytochemical method and their mRNA levels were examined by in situ hybridization.Results Compared with control group,the directional chemotactic migration of SKOV3 were significantly decreased after treated with 20 ?mol/L and 40 ?mol/L genistein,reached to(46.9?5.8)% and(28.3?4.7)% respectively(P

Objective To investigate the intelligence development status of the low birth weight infants and its influence factors. Methods The intelligence developments of 135 low birth weight infants aged 6-30 months were investigated using Bayley Scales of Infant Development, and the self-development influential factors were analyzed with questionnaire.Results The average of MDI was 86.76±18.95 in 135 infants,of which the detection rate of MDI<80 points accounted for 17.8%and the detection rate of PDI<80 points accounted for 29.6%;birth weight of infant,age,the degree of parents,culture and feeding way had significant effects on MDI in infants;age and birth weight had significant effects on PDI in infants. Conclusion The development level of infants is influenced by multi-factors. More attention should be paid to reduce premature and low birth weight infants,improve the degree of parents' culture, advocate breastfeeding and conduct early intervention in order to assure the intelligence development of infants.

Objective To explore the mechanism of Exenatide-induced rat pancreatic tissue lesion.Methods Thirty SD male rats were divided into three groups according to complete random design,and each group had 10 rats,namely Exenatide group,diabetes-model group and control group.Diabetes-model rats were induced by streptozotocin (STZ,35mg/kg) and high-sugar and high-fat diet.The Exenatide group and diabetes group were subcutaneously administered with Exenatide at a dose of 5 μg/kg twice a day.The control group was treated with same amount of saline.Ten weeks later,all the rats were sacrificed and the pancreatic tissues were harvested for routine pathological examination.Immunohistochemical method was used to detect the expression of α-smooth muscle actin (α-SMA) and type Ⅲ collagen protein in pancreatic tissue,and ELISA was applied to measure the expression of matrix metalloprotei-nase-2 (MMP-2) and MMP-9 in pancreatic tissue.Results In control group,there was no pathological change in pancreatic tissue.In Exenatide group,chronic inflammatory changes were observed; and the degree of inflammatory changes were much severe in diabetes group,and the pathological scores were gradually increased in the 3 groups (P <0.05).The expressions of MMP 2 in pancreatic tissue in control group,Exenatide group,diabetes group were (186.98 ± 23.24),(306.07 ± 59.82),(365.08 ± 89.55) μg/L,and the expressions of MMP-9 were (49.37 ± 7.08),(67.24 ±14.73),(87.37 ±13.39)μg/L.The values were significantly higher in Exenatide group and diabetes group than those in control group (P < 0.05),but the difference between the two groups was not statistically significant.The numbers of α-SMA positive cells per high power field were (13.4 ± 5.97),(29.5 ± 8.80),(79.3 ± 27.23) in control group,Exenatide group,diabetes group,and the numbers of type Ⅲ collagen positive cells were (10.6 ± 4.93),(29.3 ± 12.95),(56.0 ± 27.21).The values were significantly higher in Exenatide group than those in control group,and the values were significantly higher in diabetes group than those in Exenatide group (P < 0.05).Conclusions Long-term subcutaneous injection of Exenatide may activate pancreatic stellate cells and cause expression of α-SMA,Ⅲ collagen protein,and MMP-2,MMP-9,then induce chronic inflammatory changes.

Objective To explore the method and effect of checklist tool implemented in the safety management of clinical blood transfusion in intensive care unit. Methods A checklist was specially designed according to the technical standard and check system of clinical blood transfusion. 379 patients prescribed a blood transfusion enrolled in ICU from January to May 2013 were conducted as the control group before the checklist was designed. After the application of checklist during the blood transfusion process, 846 patients prescribed a blood transfusion enrolled in ICU from June to December 2013 were conducted as the experimental group. The incidence of blood transfusion safety related adverse events between the two groups was compared. Results The incidence of adverse events was 1.32% (5 of 379 patients) in the control group, and there was no sign of adverse events occurred in the experimental group. The difference had statistical significance (χ2=11.21, P<0.05). Conclusion The application of checklist reduced the incidence of blood transfusion safety related adverse events,and effectively improved the quality of nursing safety and patient satisfaction.

Objective To investigate the serum level of visfatin, C-reactive protein (CRP) and monocyte chemoattractant protein-1 (MCP-1) in patients with polycystic ovarian syndrome (PCOS), and provide the basis for understanding the pathogenesis of PCOS. Meth-ods 94 patients with PCOS and 100 healthy subjects were divided into 4 subgroups according to their body mass index(BMI), including obese PCOS subgroup(n = 52), non - obese PCOS subgroup (n = 42), obese healthy subject subgroup (n = 43) and non - obese healthy subject (n = 57). Serum visfatin, CRP, MCP-1, sex hormone levels and metabolic parameters were measured by enzyme-linked immu-nosorbent assay (ELISA), automatic chemistry analyzer or chemiluminescent immunoassay. Results Serum levels of testosterone (T), lu-teiizing hormone (LH) and prolactin (PRL) in the PCOS group were significantly higher than those in healthy subjects group(P <0.05~0.01), and follicle-stimulating hormone (FSH) levels were significantly decreased in PCOS group(P<0.01). Serum levels of Visfatin, CRP, MCP-1,fasting insulin(Fins) and insulin resistance homa model (HOMA-IR) in the obese or non - obese PCOS subgroup were signif-icantly increased than that in the obese or non - obese healthy subjects subgroup respectively (P<0.01). Pearson correlation analysis showed that the visfatin, CRP and MCP-1 levels were positively related to BMI, FINS and HOMA-IR(r=0.323~0.675, P<0.01). Par-tial correlation showed that serum visfatin levels were correlated with HOMA-IR(r=0.491, P<0.01), and serum MCP-1 levels were cor-related with LH (r=0.267, P<0.05) in the PCOS group. Conclusion The patients with PCOS had higher visfatin, CRP and MCP-1 lev-els, and visfatin levels were positively correlated with insulin resistance. Obesity were involved in the chronic inflammation course in patients with PCOS.
