Background and purpose:Ovarian cancer is one of three common malignant tumors in the female reproductive system,whose mortality is the highest in all of the gynecological cancers.The genetic instability and hypermutation rate of tumor cells were found to be associated with chemotherapeutic resistance,and accounted for the high recurrence rate and the failure of current treatment.Invasion and metastasis of tumor are closely related to angiogenesis.Experiments in vivo and in vitro have confirmed that there are many kinds of promoter and suppressor of angiogenesis in primary malignant tumor cells.Angiogenesis could be a potential molecular target for cancer treatment.Endostatin is a specific inhibitor of vessel endothelium.Animal experiments have confirmed that Endostatin could inhibit tumor growth through anti-angiogenesis and result in the decrease of invasion and metastasis of cancer,and it would not easily induced drug resistance in the cells.Thus Endostatin could be safely used for a variety of cancer treatments,being able treat any patho-angiogensis.Recently it has been reported that Endostatin may significantly enhance anti-tumor effects when it is combined with traditional treatment methods such as surgery,chemotherapy,radiotherapy and immunotherapy.Although the study of Endostatin was done in vitro,the primary results were very encouraging and provide the rationale for future clinical trials.In this study,we aim to evaluate the inhibitory effect of Endostatin on SKOV_(3) cell and to investigate the possible mechanism of the inhibition.Methods:1.The effects of Endostatin on SKOV_(3) cells proliferation was studied by means!of MTT.2.The cell apoptosis and cell cycle were detected by transmission electron microscope and cell flow cytometry.3.bcl-2 and bax expression were determined in SKOV_(3) cell by immunocytochemistry,RT-PCR and Western blot analysis.Results:Endostatin inhibited SKOV_(3) cell proliferation,and the value of A_(490) of 15?g/ml 72 h Endostation group(0.454) was much lower than that of PBS control group(1.369)(P

Objective: To investigate the antimicrobial resistance in and multilocus sequence typing (MLST) of Campylobacter jejuni in meat and meat products in Liaoning Province, so as to provide insights into the management of C. jejuni infection. Methods: Nine C. jejuni isolates from meat and meat products in 2020 were subjected to whole genome sequencing, and the minimum inhibitory concentration was measured with the agar dilution method. MLST of C. jejuni isolates was performed with the microbial resistance mechanism traceability reference database and analysis system. Results: Six drug-resistant C. jejuni isolates were detected, and there were four multidrug-resistant isolates. There were six C. jejuni isolates resistant to tetracycline, five isolates resistant to nalidixic acid, four isolates resistant to ciprofloxacin, two isolates resistant to florfenicol, one isolate resistant to gentamicin and one isolate resistant to streptomycin. Nine C. jejuni isolates showed sensitive to azithromycin, chloramphenicol and clindamycin. MLST identified six ST types in nine C. jejuni isolates, with ST45 and ST2274 as the predominant type, and detected one isolate with unclassified ST type. Phylogenetic analysis showed that KW028 and KW029 of ST45 type were closely related and had high homology, and KW040 and KW042 of ST2274 type were closely related with high homology, while KW007 of ST6701 type was closely related to KW040 and KW042 of ST2274 type, with only one pgm housekeeper gene in difference. Conclusions High resistance to tetracycline, nalidixic acid and ciprofloxacin was detected in nine C. jejuni isolates from meat and meat products, and ST45 and ST2274 were predominant ST types of C. jejuni.

BACKGROUND: Whether horizontal and vertical impacts cause craniocerebral injury of the same degree, and whether serum myelin basic protein (MBP) changes is associated with the direction of impact have been scarcely addressed in previous studies.OBJECTIVE: To observe the change in the serum MBP levels and morphological changes of the brain tissue rabbits with craniocerebral injury resulting from impacts from different directions.DESIGN: A randomized controlled experiment.SETTING: Department of Neurosurgery of a hospital affiliated to a medical university.MATERIALS: This study was conducted in the Central Laboratory of Shenyang Medical College between October 2003 and January 2004. Totally 30 healthy rabbits of either sex were randomly divided into two equal groups to receive vertical and horizontal impact on the head.METHODS: All the rabbits were anesthetized and fixed in prone position onto a table equipped with a device for inducing impact on the head from different directions. Venous blood of 1 mL was taken from the edge of the ear of each rabbit for detecting MBP before injury. The rabbits in vertical impact group received the impact of a hammer falling directly on the parietal bone of the skull. In the horizontal group, the rabbits were subjected to horizontal impact on the lateral side of the skull. Forty-eight hours after the injury, venous blood were again taken for MBP measurement. The rabbits were then killed for pathological examination of the brain.MAIN OUTCOME MEASURES: Changes in serum MBP and pathomorphology of the brain tissues in the two groups after the impact.RESULTS: ① According to intention to treat analysis, all the 30 animals were involved in the experiment. There was no significant difference in serum MBP levels between the two groups before the impact, nor 48 hours after the impact( P ＞ 0.05). In the vertical impact group, serum MBP levels before the impact was( 1.68 ± 0. 86) μg/L, which was significantly lower than that after the impact[ (5.25 ± 1.96) μg/L, t = 3. 226, P ＜ 0. 05]. ② In the horizontal strike group, serum MBP also significantly increased from the level of( 1.70 ± 0.91 ) μg/L before impact to(5.73 ± 2.07) μg/L after that( t = 3. 080, P ＜ 0.05) . ③ After the impact, vasodilation and congestion in the cortex near the midline of the bilateral parietal region and edema in the deep layer of the white matter were observed in the vertical impact group, along with significant enlargement of the extravascular and extracellular space. In the horizontal group, similar changes except those near the midline of the bilateral parietal region took place after the impact; the same pathological changes were also observed in the basal plane, with nearly identical pathological changes in the deep layer of the white matter.CONCLUSION: Vertical and horizontal impacts can both result in almost identical brain injuries demonstrated by similar changes in serum MBP and the pathomorphology of the brain tissues after the impacts.

Objective To evaluate the relationship between the heart diastolic function and pulse wave velocity in patients with diabetes mellitus.Methods Fifty-five patients with diabetes mellitus underwent echocardiogram exam,PWV,and BNP determination.Patients were divided into two groups according to the results:the group with normal heart diastolic function(n =33)and the group with abnormal heart diastolic function( n =22).Another 30 healthy volunteers served as control group.The values of PWV were compared.between the three groups.The relationship between E/E' and PWV,BNP and PWV were evaluated with correlation analysis.Results The PWV value of abnormal heart diastolic function group was significantly higher than that of other two groups.PWV was positively correlated with E/E'and BNP ( r =0.58,P ＜ 0.05 ; r =0.63,P ＜ 0.05).Conclusion PWV is associated with the heart diastolic function.PWV can serve as an important factor to predict abnormal heart diastolic function in patients with diabetes mellitus.
