ABSTRACT
OBJECTIVE To eval uate the effectiveness ，safety and economy of deferasir ox for the treatment of iron overload in thalassemia with rapid health technology assessment ，and to provide evidence-based basis for rational clinical use. METHODS Retrieved from Chinese and English database/website as PubMed ，Embase，Cochrane Library ，NHS EED ，CADTH，CNKI and Wanfang database ，health technology assessment （HTA），systematic evaluation/meta-analysis and pharmacological studies about deferasirox versus deferoxamine/deferiprone for the treatment of iron overload in thalassemia were collected from the inception to June 2021. Based on literature screening and data extraction ，the quality of literature about HTA reports ，systematic evaluation/ Meta-analysis and pharmacoeconomic research were evaluated with HTA checklist ，A Measurement Tool to As sess Systematic Reviews，standard scale of economic evaluation report. The effectiveness and safety results were described quantitatively ，and the economic evaluation results were described qualitatively. RESULTS One HTA report ，five systematic evaluation/meta-analysis and five pharmacoeconomic studies were selected from 1 569 literature. Included HTA reports ， systematic evaluation/meta-analysis，pharmacoeconomic studies were high in quality. Most studies reported that 30 mg/（kg·d） deferasirox was E-mail：aydgs@126.com better than deferoxamine in reducing the levels of s erum ferritin and liver iron overload ；ADR induced by deferasirox were mainly gastrointestinal irritation symptoms ，skin itching ，joint pain，transaminase elevation ，etc.，which generally did not affect subsequent treatment. There was no statistical significance in severe ADR between deferoxamine group and deferasirox group [RR ＝0.96，95％CI（0.85，1.08），P＝0.52]. Compared with deferoxamine，deferasirox had higher cost-effectiveness ；but deferasirox was less likely to be cost-effective than deferiprone. CONCLUSIONS Deferasirox has good effectiveness and safety for iron overload in thalassemia ，and has good economic advantages in Britain and Iran ，compared with deferoxamine.
ABSTRACT
OBJECTIVE To establis h and validate a population pharmacokinetic model of docetaxel in malignant tumor patients. METHODS The clinical data of malignant tumor patients treated with chemotherapy regimen containing docetaxel in our hospital from June 2019 to December 2021 were retrospectively collected . According to the results of blood concentration detection ， based on the three -compartment model the nonlinear mixed effect model （NONMEM）was used ；covariates（age，weight，height， body surface area ，Karnofsky performance scale ，total protein ，albumin，total bilirubin ，aspartate aminotransferase ，alanine aminotransferase and serum creatinine ）affecting clearance （CL）were screened by “forward inclusion and backward exclusion ”； the population pharmacokinetic model of docetaxel was established . The model was tested for goodness -of-fit diagnosis and internal validation by Bootstrap . RESULTS A total of 264 measured blood concentrations of 132 patients with malignant tumors during chemotherapy were included . The covariates that had significant effect on CL of docetaxel were serum creatinine and total bilirubin （P＜0.01）. The results of Bootstrap analysis （parameter median values and 95% confidence intervals ）were close to predict results of the established model ；the final model estimated that the population typical value of docetaxel CL was 37.82 L/h. CONCLUSIONS The population pharmacokinetic model of docetaxel in malignant tumor patients is established successfully ， which can be used for the formulation and optimization of clinical individualized regimen .
ABSTRACT
In order to achieve the quality control goal of medical devices in hospital,this paper analyzes difficulties in metrological control,introduces a kind of hospital metrological management mode and its principle,and expounds its function,possible questions and explanations as well as application methods.
ABSTRACT
Taking 5 modes of large-scale X-ray apparatus as examples including GE TX-Ⅲ 500mA, Shimadzu ED125L 500 mA, GE VR 500 mA, Siemens Tridoros 5S 1 000 mA, Siemens Heliophos 5S 500 mA, the replacement techniques are introduced in such aspects as the preparation of rooms and tools before replacement, disassembly, transport, reinstallation, electrifying and test. Cooperation of personnel is an important factor to smoothly complete the task.
ABSTRACT
With the expanding development of engineering of medical service,medical engineering department should adapt to hospital development.Expanding principle and the goal of medical engineering department are expounded.The fundamental content of the expanding strategy includes mechanism of purchasing and purveying,construction and management of both equipment maintenance and medical metrological organization,training to faculty of specialized subject,orientation of scientific research,etc.
ABSTRACT
This paper aims to establish an evaluation target system on military medical measurement so as to increase effectiveness of metrological management on military medicine. According to evaluation method of modern industry measurement, principles of engineering economy and quality requirement of health service, such relative evaluation targets as normal military medical evaluation target, health service department evaluation target and economic effect evaluation target are expounded and proved. This system has a valuable reference to the evaluation of military.medical measurement
ABSTRACT
Objective: To evaluate economic benefits of military medical measurement. Methods: According to the record of the metrological verification from the measurement station in Nanjing military region from 2000 to 2004, database is set up by Excel 2003 and the economic benefits from 14 kinds of measuring standard are analyzed. Results In a 5-year-lifetime cycle, the NPV of 10 kinds of measuring standards were over 0, 4 kinds less than 0, the average pay back period was 4.43year, and total benefit cost ratio was 2.73. Conclusion Economic benefits have been gained obviously in the investment of military medical measurement.
ABSTRACT
A new measurement management thought satisfying actual demands and the requirements of the coming war is put forward in this paper. Combining the reality of military medical measurement, related support modes at peacetime and wartime as well as supervising modes are analyzed in detail. Several kinds of support modules their logical relations are mentioned.
