OBJECTIVE:To understand features of ADR in our hospital and to promote rational clinical drug use.METHODS:A retrospective method was adopted in which 557 ADR cases collected in our hospital in 2004 were analyzed from aspects of reporters,drug categories,routes of administration,the top 10 ADR-induced drugs and etc.RESULTS:Antibacterial and the traditional Chinese medicine injectable preparation dominated the first place and the second place respectively on the list of ADR report cases;55.83%of the ADR cases was induced by IV drop drugs;Clindamycin injection has the highest incidence rate of ADR;63.91%ADR cases were come from pharmacists.CONCLUSION:Carrying out ADR monitoring work is an important task for medical institutions,the strengthening of ADR monitoring can ensure safe drug use of patients.

AIM: To investigate the expression and the significance of β-catenin and Cyclin D1 in gliomas. METHODS: The SABC immunohistochemistry were used to detect the expression of β-catenin and Cyclin D1 in 49 brain gliomas and 5 normal brain tissues. RESULTS: The β-catenin positive ratio in normal brain tissues and glioma samples are 2/5 and 38/49(P<0.01) respectively, and the Cyclin D1 positive ratio in normal brain tissues and gliomas are 1/5 and 42/49(P<0.01); Compared with the normal brain tissue, both the immunohistochemical expression of β-catenin and Cyclin D1 were up-regulated(P<0.05), and the expression of β-catenin and Cyclin D1 between the normal brain tissues and gliomas exhibited significantly difference (P<0.01). CONCLUSION: β-catenin and Cyclin D1 increased in gliomas may be precipitate the tumorigenesis of glioma.

Brain metastasis of epidermal growth factor receptor (EGFR) sensitive mutations is a hot and difficult point in targeted era of non-small cell lung cancer (NSCLC) treatment, meanwhile it is also the central issue of controversy in the field of lung cancer treatment. Different results of different studies and different understanding of different disciplines, this field of treatment has been accompanied by different voices, patients without clinical symptoms can use targeted therapy first, and then start local radiotherapy with clinical symptoms or disease progression. It is a major model of the medical oncology. That is to say, taking symptoms and progress as indication and standard of local treatment intervention. In the absence of symptoms, local radiotherapy may increase patients' pain, which belongs to overtreatment. However, the perspective of radiotherapy is that brain metastases need to be treated clinically as early as possible, if not, it may affect the survival of patients. Early treatment of local lesions and increasing the depth of treatment are helpful to prolong the survival time of patients. This article refers to relevant literatures and summarizes the discussion from the perspective of pursuing the truth of disease treatment and problem solving in order to provide reference for patients' clinical practice.

OBJECTIVETo develop a bacteria expression system to produce the fusion protein of humanized anti-HBsAg scFV and interferon-alpha.

METHODSThe expression vector was constructed after cleaving the plasmids harboring the humanized anti-HBsAg scFv and interferon alpha respectively and ligating to linearized pET22b subsequence. The expression of fusion protein in E.coli was analyzed by SDS-PAGE. The binding activity and antiviral activity of the fusion protein was characterized by competing inhibition test and cytopathic effect reduction.

RESULTSThe plasmid harboring the in frame arranged fusion gene was constructed and identified. After induction for 12h, a new band close to 4.5 10(4) was observed using SDS-PAGE. Results of competing ELISA and cytopathic effect reduction showed the fusion protein retained its specific binding activity and antiviral activities.

CONCLUSIONSThe construction and expression of the fusion gene of humanized anti-HBsAg scFv and interferon in E.coli are successful.

Objective: To establish a rabbit unstable bladder and Partial Bladder Outlet Obstruction (BOO) model, and to study on urodynamic changes. Methods: 30 male New Zealand rabbits were divided into control group and operative group. After 8 weeks, urodynamic changes were determined after they were anaesthetized by ketamine and droperidol. Results: Prominent changes of Main urodynamic parameters were found between the operative group and control group. The incidence rate of unstable bladder was 60%. Conclusion: The method of establishing rabbit model of Partial BOO is successful. It provides a platform for the study on the changes of pathology and pathophysiology of human chronic partial BOO and treatment of this kind of diseases.

Objective To investigate the utilization rate of gold fiducial markers and reasons for abandonment of gold fiducial markers in the CyberKnife VSI System, and to provide reference data for implantation of gold fiducial markers and radiotherapy planning. Methods From March to August,2017,a total of 47 patients had gold fiducial markers implanted or pasted. In those patients, 42 patients had gold fiducial markers implanted,including 32 receiving computed tomography(CT)-guided 3D-printing coplanar template assisted implantation, 1 receiving CT-guided 3D-printing non-coplanar template assisted implantation,1 receiving CT-guided implantation,and 8 receiving ultrasound-guided implantation. A total of 44 patients received the CyberKnife treatment, including 2 patients who failed to use gold fiducial markers and were treated with spine tracking instead and 3 patients missing the treatment for other reasons. The numbers of utilized and abandoned gold fiducial markers were recorded for calculation of the utilization and abandonment rates. The reasons for abandonment of gold fiducial markers were analyzed and classified. Results A total of 134 gold fiducial markers were implanted into or pasted to the 44 patients.In all the gold fiducial markers, 111 were utilized and 23 abandoned, yielding a utilization rate of 82.8% and an abandonment rate of 17.2%.The reasons for abandonment of gold fiducial markers included large rigidity error(26.1%), unqualified implanted fold fiducial markers(17.4%), displacement of gold fiducial markers(26.1%), and others(30.4%). Conclusions Compared with the CT-guided or ultrasound-guided implantation of gold fiducial markers, the CT-guided 3D-printing coplanar or non-coplanar template assisted implantation of gold fiducial markers requires only two puncture needles for each implantation and implants two gold fiducial markers by a single needle,which reduces the number of puncture needles,risk of puncture-induced injury,and incidence of complications after implantation. Not all the gold fiducial markers implanted by a variety of ways will be utilized. Some gold fiducial markers will be abandoned for different reasons,which should be taken into account during implantation of gold fiducial markers.
