Objective To explore the difference of the results between pup smear and liquid-based cytology (TCT) in cervical lesions.MethodsA total of 150 patients undergoing routine cytology were enrolled in the department of obstetrics and gynecology in Hangzhou Wuyunshan sanatorium from May 2015 to December 2016.The patients were treated with liquid-based cytology (TCT) and Papanicolaou Smear examination;and liquid-based cytology method as the study group, and Pap smear the control group.The difference of the diagnostic results between the two groups were compared.ResultsThe positive rate of ASCUS detection, LSIL detection rate and HSIL detection rate were significantly higher in the study group than those in the control group (P<0.05).The difference between the two groups was statistically significant (P<0.05).Compared with the results of colposcopic biopsy, the diagnosis of LSIL coincidence rate in the study group was significantly higher than that in the control group, the difference between the groups was statistically significant (P<0.05).ConclusionCompared with pap smear examination, liquid-based cytology has a more obvious advantage in cervical lesions, which can significantly improve the positive rate of cervical lesions, reduce the false negative results, with a higher diagnostic compliance rate, and therefore worthy of clinical application.

Objective To study and observe the changes of pancreatic blood flow and blood miR indexes of patients with pancreatic cancer.Methods 70 patients with pancreatic cancer were selected as the observation group,70 health persons of the same age at the same period were selected as the control group, then the blood flow indexes and blood miR of observation group’s lesion and tumor adjacent tissue and control group’s healthy pancreas were detected,and the detection results of control group and observation group were compared,then the above indexes of observation group with different Hemrick stages were compared.Results The lesion blood flow indexes of observation group were all obviously worse than those of control group(P<0.05),blood miR indexes were all higher than those of control group(P <0.05),the lesion and tumor adjacent tissue blood flow indexes all had obvious differences(P<0.05),and the above indexes of observation group with different Hemrick stages all had significant differences(P<0.05).Conclusion The pancreatic blood flow and blood miR of patients with pancreatic cancer all show obvious abnormal state,and the differences of indexes of patients with different Hemrick stages are all prominent, so the pancreatic blood flow and blood miR indexes all have higher value for the patients with pancreatic cancer.

ObjectiveTo investigate the mentation of the female in mammography examination. Methods292 female patients (over 35 years old) from the out-patient department accepted the psychological questionnaire survey.ResultsMost female patients showed some mental problems, include angst, discomposure, tension or funk for examination. They worried about examination result and the damage being exposed to the X-ray irradiation.ConclusionTechnicians should pay attention to the mentation of the female in mammography examination to win their trust and cooperation.

AIM:To investigate the effect of tanshinone IIA on the apoptosis of human umbilical vein endothe -lial cells (HUVECs) after high glucose treatment.METHODS:The cell viability was determined by MTT assay.The cell apoptotic rate was examined by flow cytometry with Annexin V-FITC/PI double staining .The expression of Bcl-2 and Bax, and the release of mitochondrial cytochrome C ( Cyt C) were analyzed by Western blotting .RESULTS: Tanshinone IIA significantly inhibited high glucose-induced decrease in cell viability and increased the cell apoptosis .Additionally, after tanshinone IIA treatment , Bax expression and the release of mitochondrial Cyt C were significantly inhibited , while Bcl-2 expression was increased .CONCLUSION: Tanshinone IIA prevents high glucose-induced endothelial cell apoptosis via mitochondria-dependent pathway .

OBJECTIVE To investigate the incidence of integrons in Pseudomonas aeruginosa strains isolated from blood samples in Peking University People′s Hospital and to analyze the correlation between integrons and drug resistance of P.aeruginosa.METHODS Forty-two strains of clinically isolated P.aeruginosa were collected.The antibiotics susceptibility was tested by K-B methods.Integrase gene of integron was amplified by PCR using degenerate primers.The integrons were classified by restriction fragment length polymorphism(RFLP) analysis of positive PCR products with Hinf Ⅰ restriction enzyme.RESULTS The drug-resistance rates of 42 strains of P.aeruginosa against 20 kinds of antibiotics ranged from 9.5% to 100%.Twenty-three strains were resistant to 12 kinds of antibiotics.Nineteen of the 42 isolates(45.2%) contained integrons,all of which were revealed as class Ⅰ of integrons by RFLP analysis.Neither class Ⅱ nor class Ⅲ of integron was detected.The positive percentage of integrons was increased by years.CONCLUSIONS Class Ⅰ integrons are widespread in isolates from blood samples in our hospital.The presence of integrons is closely associated with multi-drug resistance of P.aeruginosa.

Objective:To isolate mesenchymal stem cells (MSCs) from mouse fetal liver and induce them differentiate into islet B-like cells. Methods:MSCs were isolated from C57BL/6J mouse fetal liver and were induced with high concentration of glucose, basic fibroblast growth factor(bFGF) ,and nicotamine medium. The gene expressions related to islet B cells such as pancreatic duodenal homeobox-1 (PDX-1), proinsulin-1 (INS-1) ,and glucose transporter-2 (GLUT-2) were detected by RT-PCR. Insulin in the treated cells was examined by immunocytochemistry. The insulin clusters were stained with dithizone (DTZ), a zinc-chelating agent known to selectively stain pancreatic B cells. Results: RT-PCR showed that the treated cells expressed PDX-1, INS-1 and GLUT-2, while the undifferentiated cells did not. After approximately 10 d of treatment, the fetal liver cells formed DTZ-stained cell clusters in flasks (80-120 clusters in a flask 25 cm2 in area). Immunocytochemistry also confirmed that these aggregates were strongly positive for insulin. Conclusion: MSCs derived from fetal liver can be induced into islet B-like cells in vitro.
