ObjectiveTo investigate the effects and problems of problem-based learning ( PBL ) teaching methods that are adopted in the laboratory medicine practice teaching. MethodsOne hundred and four undergraduate students of 5-year system of laboratory medicine were selected to use the PBL teaching methods during the laboratory medicine practice. ResultsIt showed that the PBL teaching methods obtained good probation effect. But teachers and students are required to make greater efforts in PBL teaching mode than in traditional mode, and the teaching methods was also needed to be consummated.ConclusionsUsing the problem-based teaching methods the comprehensive ability of the student is enhanced. Therefore it deserves to be generalized during laboratory medicine practice teaching.

Objective To analyze the drug-resistance and distribution of nonferments bacteria infection in our hospital and provide the diagnosis and treatment evidence to doctor.Methods 241 nonferments bacteria strains had been separated from patients of Xinqiao Hospital from July 2006 to Jan 2008. Bacteria identify and drug-resistance test were performed by VITEK-Ⅱanalysis system. The drug-resistance result was determined by MIC with the standard of NCCLS.Results The separate rate in patients of neurosurgery, respiration, orthopaedics were 24.94、23.27 and 10.79 respectively. The main source of specimen are sputum. The drug resistance rate were Imipenem (16.9), Amikacin(29.3), Cefepime (33.9) and Cefazidime(39.1) in 241 nonferments bacteria strains. Conclusion The infection of nonferments bacteria must be recognized by doctors, and it would prompt us to use antibiotic properly.

Objective To investigate the value of Habib 4X in hepatic resection. Methods The clinical outcome of 21 patients with liver disease who received liver resection at the Tianjin Third Central Hospital from November 2009 to April 2010 were retrospectively evaluated. All the operations were carried out by using Habib 4X. Results All patients received hepatectomy, including right hepatectomy in three patients, left hepatectomy in one patient, multiple segmentectomy in nine patients, single segmentectomy in seven patients and partial liver resection in one patient. All tumors were reseeted completely. The mean operation time was (50±25) minutes and the mean blood loss was(129±117)ml. No patient was transferred to ICU. Three patients were complicated with bile leakage, one with lymphatic leakage and four with pleural effusion, and they were cured by non-surgical treatment. There were no patients with postoperative hemorrhage, incision infection or hepatic failure. No mortality was observed. The mean postoperative hospital stay was(19±14)days. Conclusions Radiofrequency energy was applied along the margins of the tumor to create zones of necrosis before resection with a scalpel, offering hepatobiliary surgeons an additional method for performing liver resections with minimal blood loss, low morbidity and mortality rates. As for malignant tumors, minor or major liver resection assisted by Habib 4X is safe, and it can reduce the chance of positive incisal margin.

At present, TCM treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) is based on the combination of disease differentiation and syndrome differentiation. Therefore, the establishment of IBS-D of liver stagnation and spleen deficiency syndrome combined with animal model as a combination of traditional Chinese and Western medicine innovation theory has become increasingly concerned about, and gradually become a new direction for the development of TCM experimental animal model. This article reviewed the research progress in IBS-D liver and spleen deficiency syndrome in recent years, discussed the establishment of IBS-D liver stagnation and spleen deficiency animal model and research ideas for the treatment of IBS-D, and provided references for mechanism research of TCM treatment for IBS-D and research and development of new medicine.

Quench of magnetic resonance imaging system refers to the process that the superconducting condition inside the magnet is destroyed due to some reason. The large current stored in the coil is quickly converted into heat at the place where the resistance is formed, and a large amount of liquid helium in the magnet is evaporated. If it happens, it will cause huge loss to the user. We introduce the real cases of 1.5 T magnetic resonance imaging system's quench fault, maintenance treatment and management improvement, which can be used for reference by various medical institutions, so as to better strengthen the operation and maintenance management of magnetic resonance imaging system, so as to avoid the occurrence of out of tolerance fault, and do a good job in the guarantee work after the out of tolerance fault.
