Objective To analyze the clinical symptoms and CT findings of fungus sinusitis in order to evaluate CT diagnosis. Methods To analyze retrospectively the collected data of 12 patients who underwent operations for fungos sinusitis which was proved pathologically. Results The main clinical feature of fungos sinusitis was bloody supperative rhinorrhea in all cases. In the CT scans, we found the density of the involved sinus cavities rised inhomogeneities in all patients. CT scans also showed spot-like calcification in 7 cases, bony proliferation in 5 cases and bony absorption in 2 cases. The operation revealed a lot of filthy or inflammatory polypoid substances in the involved sinus cavities in all patients. Pathological examination demonstrated clusters of fungus in the filthy substances. Conclusion The diagnosis of fungus sinusitis mainly derived from clinical symptoms and radiological examinations. The final diagnosis depended on pathology. It is of great value for reference that CT scans can show the anatomical structures of the sinuses and help to diagnose fungus sinusitis.

OBJECTIVE: To investigate the relationship between single nucleotide polymorphism of gene and ischemic stroke and search for predisposing genes of ischemic stroke.DATA SOURCES: The Medline database was searched for articles of gene polymorphism of fibrinogen and ischemic stroke published from 1980 to 2005 with the key words of "stroke, plasma fibrinogen, polymorphism"in English. Meanwhile, Vip Information Database was also searched for literatures of gene polymorphism of fibrinogen and schemic stroke published between 1995 and 2005 with the key terms of "ischemic stroke, fibrinogen,gene polymorphism" in Chinese. Full-texts were gotten by correspondence with the authors.STUDY SELECTION: Included literatures were only case control study literatures. Literatures of contrast study, experience summary, individual case and so on were excluded.DATA EXTRACTION: Totally 50 articles of gene polymorphism of fibrinogen and ischemic stroke were retrieved. Twenty articles were accorded with inclusive criteria, and thirty articles were excluded.DATA SYNTHESIS: Level of plasma fibrinogen was co-affected by heredity and environment. Gene polymorphism of fibrinogen has important regulatory effects on the level of plasma fibrinogen. The fibrinogen accelerates thrombotic formation. As a result, the incidence rate of ischemic stroke increased by participating atherosclerosis, helping thrombocytic aggregation and changing the status of hemorheology. But definite mechanism and molecular function of gene polymorphism of fibrinogen deserved further research.CONCLUSION: The relationship between single nucleotide polymorphism of fibrinogen and ischemic stroke remains obscure. It also needs further study.

Objective To study the clinical efficacy of epirubicin combined with paclitaxel in the treatment of three negative breast cancer.Methods 100 patients with breast cancer who were treated in Shanxi Cancer Hospital from January 2014 to December 2016 were selected as the research object in this study.They were randomly divided into the control group and the experimental group, with each group having a total of 50 patients.The control group was treated with epirubicin, and the experimental group was treated with epirubicin combined with paclitaxel.The short-term remission rate, Karnofsky score and the incidence of adverse symptoms were compared between the experimental group and the control group.Results After treatment, the Karnofsky score of the experimental group was(89.76±10.12), and the Karnofsky score of the control group was(71.23±11.67).The Karnofsky score of the experimental group was significantly higher than that of the control group (P<0.05).In the experimental group, the number of short-term remission was 44 cases, the short-term remission rate was 88.0%, and the number of patients in the control group in the recent remission was in the number of cases, the short-term remission rate was 72.0%, and the number of patients in the control group was about 36.The results showed that the short-term remission rate of the experimental group was significantly higher than that of the control group, with statistical difference (P<0.05).After treatment, there was no significant difference between the control group and the experimental group in the incidence of complications, which was not statistically significant.Conclusion The clinical effect of doxorubicin plus paclitaxel in the treatment of three negative breast cancer, can improve the remission rate in a large extent, improve the quality of life of patients, with further clinical promotion and application significance.

Objective To review the biologic characteristics and biologic effect of cholecystokinine (CCK) on the central nervous system. Methods The literatures of recent years on research advancement of cholecystokinine as neurotransmitters/peptides in signal transduction, neuron protection and pain management in the central nervous system are reviewed. Results CCK possesses the ability to suppress the convulsant effects of convulsants. CCK8 is able to reduce the neural damage caused and delay the neural aging. CCK antagonists play an important role in human pain transduction. Conclusion CCK has been proven to be one of the richest neurotransmitters/neuropeptides as well as an important signal factor in the brain, and its important biologic effect is being confirmed.

Objective: To amplify two human mutant CD59 eukaryotic expressing systems and investigate mutant CD59 functional activity. Methods: Mammalian expression vector PLATER of mutant CD59 cDNAs was transfected into CHO together with the pcDNA by lipofectamine,which confered resistance to G418(400 ?g/ml). The positive clones were tested by FIH. Activity of both mutants CD59 was determined by BCECF release assay. Results: Mutant CD59 cDNAs subcloned into the mammalian expression vector PLATER and transfected CHO together with the pcDNA,which confered resistance to G418. The positive clones were tested by FIH.Activity of both mutants CD59 before and after glycation was determined by BCECF release assay,both of them could restrict MAC formation ,and glycation could inhibit CD59. Conclusion: A eukaryotic system that expressing mutant CD59 cDNA was successfully set up.It was found that mutant CD59 could restrict MAC formation,and glycation could inhibit mutant CD59. These would be helpful for the furthur study of link mutant CD59 and the vascular proliferative of diabetes.

Purpose:To study if tamoxifen (TAM) can induce growth arrest and apoptosis of ER negative MA782 mouse breast cancer cell line and to explore the molecular mechanisims. Methods:MA782 cells were cultured in RPMI 1640 medium with TAM.The proliferative activity of cells was detected by MTT methods, and cells apoptosis by flowcytometric methods. The expression of cyclin D1, CDK4 and TGF ?1 proteins was detected by immunohistochemical methods, the semi quantification of protein expression was analyzed by pathological image analysis software.Results:TAM can induce growth arrest and apoptosis of cells. ICC results showed that MA782 cells were ER negative. There was no change of cell cycle regulators in cells with 2 ?mol/L TAM. After 48、72h with 6 ?mol/L or 10 ?mol/L TAM, the level of cyclin D1 proteins decreased from 132.5?0.02 to 129.67?0.03、126.18?0.03(6 ?mol/L) and 109.1?0.01、73.56?0.02(10 ?mol/L),CDK4 proteins decreased from 107.2?0.01 to 91.23?0.02、76.21?0.03(6 ?mol/L)and 83.52?0.02、72.03?0.01(10 ?mol/L), while TGF ?1 proteins increased from 59.72?0.02 to 83.2?0.04、121.75?0.03(6 ?mol/L)and 96.83?0.02、139.01?0.05(10 ?mol/L),The difference was significant( P

Objective To compare the safety and effectiveness of temporary occlusion techniques with different balloons in performing cesarean section for patients with pernicious placenta previa.Methods The clinical data of 15 patients with pernicious placenta previa,who received cesarean section during the period from March 2014 to April 2016,were retrospectively analyzed.In order to reduce bleeding during operation and to preserve the uterus as far as possible,temporary occlusion of abdominal aorta with balloon was adopted in 7 patients (group A),and temporary balloon occlusion of bilateral internal iliac arteries was employed in 8 patients (group B).The intraoperative radiation dose,the amount of blood loss and blood transfusion during cesarean section,the hysterectomy rate,the postoperative hospitalization days,and the intervention-related complications were documented,and the results were compared between the two groups.Results All the 15 patients were suffered from central type of placenta praevia complicated by extensive placenta accreta.With the help of temporary balloon occlusion technique,the cesarean section was successfully accomplished in all 15 patients.Subtotal hysterectomy had to be done in 7 patients,including 4 patients of group A and 3 patients of group B,and every one patient from each group developed arterial thrombosis of lower limb.The intraoperative radiation dose of group A was significantly lower than that of group B (P＜0.01),besides the amount of blood loss and blood transfusion during cesarean section,the hysterectomy rate,the postoperative hospitalization days,and the intervention-related complications of group A were all lower than those of group B,but because of the limited number of cases these differences were not statistically significant (P＞0.05).Conclusion For the treatment of pernicious placenta previa,temporary balloon occlusion technique-assisted cesarean section is safe and effective.The intraoperative radiation dose in the group using temporary balloon occlusion of abdominal aorta is remarkably lower than that in the group using temporary balloon occlusion of bilateral internal iliac arteries.

Opioid dependence is based on compensatory adaptations in neurons following chronic exposure to opioids. Recent researches show antagonists of N methyl D aspartate (NMDA) receptors inhibit physical and psychic dependence on opioids. This review focuses on the interactions between opioid receptor system and NMDA receptor system, and on the molecular mechanisms of NMDA receptor contributing to opioid dependence. The clinical prospects of NMDA receptor antagonists and related substances on preventing and treating opioid dependence are aslo discussed.
