Chinese Journal of Biochemical Pharmaceutics 2017;37(6):383-384
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.
2.Change of pancreatic blood flow and blood miR indexes in pancreatic cancer
Chinese Journal of Biochemical Pharmaceutics 2016;36(8):136-138
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.
4.Mentation of the Female in Mammography Examination
Chinese Journal of Rehabilitation Theory and Practice 2006;12(5):459-459
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.

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.

Objective Insulin resistance is a possible cause of polycystic ovary syndrome(PCOS).It is presumed that ectonucleotide pyrophosphatase/phosphodiesterase 1(ENPP1) is associated with insulin resistance.The purpose of this study is to explore the expression of ENPP1 in granulosa cells of the ovary and its relationship with PCOS. Methods Twelve aliquots of follicular granulosa cells were isolated from 12 samples of the patients with PCOS and 22 aliquots from 22 samples of the patients without PCOS,respectively.ENPP1 expression was analyzed by reverse transcription polymerase chain reaction(RT-PCR) and in situ hybridization.The relative expression of ENPP1 mRNA was detected by real-time quantitative polymerase chain reaction(real-time PCR). Results ENPP1 was expressed in granulosa cells of the ovary.ENPP1 expression's 2~(-?Ct) in granulosa cells of PCOS was significantly higher than non-PCOS(1.67?0.89 vs.0.94?0.76,P=0.017).Conclusion ENPP1 expression plays a role in ovary function and may be closely associated with the development of PCOS.

The precise measurement in lens thickness in vivo, provides great application value for intraocular accommodation and ametropia development mechanism research.And it has great clinical significance for the diagnosis and treatment of glaucoma and cataract.Currently, many ultrasonic methods and optical methods are used in measuring lens thickness.The measurement principles, advantages, disadvantages and the accuracy of the instruments are summarized in this paper.Among these methods, Orbscan II, Pentacam, Lenstar and AS-OCT can be used to measure lens thickness instead of A-scan.More important is the fact that UL-OCT can dynamically monitor the change of the lens thickness with intraocular accommodation.Choosing an instrument with higher measuring accuracy to examine the lens thickness, can provide more accurate and convincing lens thickness data for clinical and scientific research.
