OBJECTIVE: To evaluate the value as well as correlation between blood drug level and blood routine results in patients using cyclospone A (CsA) following renal transplantation via analyzing varies of immunosuppressive agents used in renal transplantation. METHODS: Retrieval-related contents were collected by computer from Chinese Journal Full-Text Database with of "renal transplantation, CsA, and therapeutic drug monitoring". Simultaneously, data of patients who received CsA treatment after renal transplantation in the Department of Laboratory, Liaoning Provincial Electrical Hospital were selected. All the literature was retried and analyzed. RESULTS: A total of 717 patients were included in the final analysis. It demonstrated that 6 sorts of immunosuppressive agents, such as mizoribine, sirolimus, zenapax, mycophenolate, and basiliximab play an important role in immune suppression after organ transplantation. However, there still exist problems need to be further explored. CsA was more suitable for clinical application with lower price and good curative effect, which worked better combined with other immunosuppressive agents. CONCLUSION: A best curative effect of CsA can be achieved by timely adjusting therapeutic regimen under the patient's condition. Meantime, a high efficiency and low toxicity drug with specific tolerance is the ultimate goal of immunosuppressive agents.

This article particularly introduces the fundamental principle of high voltage generator Jedi,function characterization of sub-assembly,signal flow,software configuration and command description,as well as their safety monitoring,information feedback,state trace.It is beneficial to the use and maintenance of the high voltage generator.

The relationship between neuronal inflammatory changes and extensive neurodegeneration in patients with multiple sclerosis (MS) remains to be studied.Recent neuroimaging studies have shown that energy depletion due to the impairment of effective oxygen metabolism and oxygen supply defects may be one of the causes of neurodegeneration.In this paper,the pathologic mechanism of MS related to energy failure and associated MRI imaging techniques were reviewed.

The common problems in the operation and maintenance of the clean operating department were summarized, and additional attention was paid on the important systems for humidifying, ventilation and filtering as well as the daily operation and maintenance of hand washing sink, electric air-lock door and etc. Some suggestions were put forward for the management of the staff and the operating department.

Objective To clarify the etiology of pathological nipple discharge.Methods Since 1990,81 patients with pathological niplpie discharge underwent mammary duct incision to identify the lesion.Results 67 patients had intraductal papilloma,5 patients had intraductal papillomatosis,6 patients had duct carcinoma,and 3 patients were not found pathological changes.Conclusions Intraductal papilloma,intraductal papillomatosis,and duct carcinoma might be the exclusive etiology of pathological nipple discharge.

Through intensifying the clinical pathological discussions and clinical pathological dissections,the clinical thinking,iatri- cal responsibility and analytical ability of the medical students have been improved markedly and the abridge function of pathology between basic medicine and clinical medicine has also been reinforced.

Objective: To prepare voriconazole long-circulation liposomes and evaluate the characteristics of pharmacokinetics in rats.Methods: Voriconazole long-circulation liposomes were prepared by a thin film dispersion extrusion method.The drug release of voriconazole from the long-circulation liposomes was investigated in phosphate buffer solution (PBS) and in rat plasma.The physicochemical properties of the long-circulation liposomes before and after the freeze-drying were studied, such as the particle diameter and the particle shape.The concentration of voriconazole in plasma was determined after tail-vein injection of the long-circulation liposomes in rats.Results: The mean particle size of voriconazole long-circulation liposomes was (192.1±49.3)nm with homogeneous small spherical morphology as seen under a transmission electron microscope.Voriconazole was released in a sustained manner in PBS while much faster in plasma from the long-circulation liposomes.The t1/2 and AUC0-t of the long-circulation liposomes was respectively 2.17 and 2.31 times higher than that of voriconazole injection.Conclusion: Long-circulation liposomes prolong the circulation time and increase the bioavailability of voriconazole.

Replacement therapy of stem cells transplantation represents a potential treatment for neural retinal diseases.Despite the encouraging results in laboratory,the clinical application of cells replacement therapy is still difficult because the limitation of seed cells,immunologic rejection,oncogenicity and ethical problems,etc.Recent breakthrough in somatic reprogramming provides a promising solution overcoming these obstacles.Further researches on virus-free reprogramming will make the clinical application of stem cell replacement therapy possible.

ObjectiveTo investigate the psychological state and care measures for patients undergoing pereutaneous coronary intervention (PCI). Methods300 patients treated with PCI from December 2009 to June 2011 in our hospital were chosen as the research object.The factors arousing psychological disorders for PCI patients were taken for comparison.And then the appropriate nursing measures were discussed. ResultsThe most evident negative emotion of PCI patients was depression.The factors arousing negative emotion included the factors of family members and undesirable environment by many people going in and out. ConclusionsEffective measures can avoid the psychological barriers of PCI patients and improve the quality of postoperative recovery for patients.

OBJECTIVE: To explore the materials and selection of esophageal stents, and to discuss the application of covered stants in treating esophageal malignant stenosis.METHODS: CNKI and Medline databases were retrieved by computer for papers published from 1980 to 2009 with search terms of "esophageal carcinoma, esophageal stenosis, esophageal stent, and fabric-covered metallic stent". The language was limited for Chinese and English. A total of 61 iteratures were initial searched by computer, according to inclusive and exclusive criteria, 29 literatures were selected by the first author. Problems including esophageal stent category, material selection, as well as application of covered stents in treating esophageal malignant stenosis were reviewed and summarized.RESULTS: Totally 29 literatures were included in this paper. No concealed allocation or blinding method was described in the literatures. According to preparing materials, the stents could be divided into stainless metal stent, memory metallic stent and polyester plastic stent. As tissue-engineered materials, stents could be assigned into biodegradable polymer matrix stent and non-degradable biodegradable polymers stent. Each material stent possesses distinct advantage and disadvantage. The covered stents could relief esophageal stenosis effectively, interrupt tumor growth, and prevent restenosis. CONCLUSION: As a palliative therapy for treating esophageal malignant stenosis, covered stents can elevate patients' life quality and prolong survival times.
