1.New advances in magnetic resonance imaging of brain metastasis
Chinese Journal of Medical Imaging Technology 2009;25(12):2306-2308
The growth of brain metastasis needs appropriate microenvironment, and the change of normal brain microenvironment is the basis for exploring metastasis with MRI. Through the local magnetic field changes and the application of contrast agents for improving the discrepancy of the cerebral tissue, MR can accurately detect brain metastasis in position, number, size, and shape. MR with contrast-enhanced technique is the first choice for screening brain metastasis. The application of all kinds of new MR techniques, sequences and intracellular contrast agents can not only further improve the specificity of detection, but also improve the sensitivity of MRI, which is favorable to formulating reasonable treatment and prolonging the lifetime of the patients. The microenvironment of brain metastasis and advances in the new MR techniques were reviewed in this article.

Objective:To study MUC1 based cancer vaccine.Methods:MUC1 gene was inserted into pMAL-p2 vector and constructed recombinant pMAL-MUC1. MUC1-MBP fusion protein expression was induced by IPTG in E coli DH5? transformed by the recombinant pMAL-MUC1 .The fusion protein was analyzed by Western blot and purified by amylose affinity chromatography. The antiserum,T cell proliferation and CTL activity of spleen from C57 mice immunized by MUC1-MBP were determined respectively by ELISA,adding 3H-TdR and MTT.Results:Had successfully constructed pMAL-MUC1 expression vector,and purified MUC1-MBP and MBP. C57 mice immunized by MUC-MBP generated MUC1 specific antibody and CTL.The titer of polyclonal antibody to MUC1 was about 1∶5 760?3 221. CTL cytotoxicity to the MCF7 and lewis lung cancer cells respectively were at 47.7%?4.3% and 67.5%?6.5%.Conclusion:Human recombinant MUC1-MBP fusion protein activated T and B cell response in mice.The results suggested that the recombinant Muc1 may be used to develop protein vaccine against carcinoma.

OBJECTIVE:
To discuss the diagnosis and treatment of esophageal perforation induced by esophageal foreign body.
METHOD:
Ten patients, who were diagnosed as esophageal foreign body and esophageal perforation, were retrospectively analyzed. One patient was operated in other hospital and transferred to our department post-operation. The foreign bodies were removed through rigid esophagoscope in 7 cases and through the tracheotomy in 1 case. The last case was admitted into hospital for abscess around the esophagus. The foreign body wasn't find during the examination of rigid esophagoscope and the patient vomited out a glass foreign body after the surgery.
RESULT:
In all cases, there were three date stones, two button batteries, one metal gear, one pin, one metal cans pull ring, one glass plate, one arc hard plastic sheet. Seven patients were cured after conservative treatment, and restored normal diet. For the rest 3 cases, patients were cured after the repair operation of tracheoesophageal fistula.
CONCLUSION
The esophageal perforation must be highly suspected of the esophageal foreign body with a long history, sharp shape or corrosive foreign body. The esophageal radiography may be taken to obtain the final diagnosis. The patients diagnosed as esophageal perforation must be treated with antibiotics, nasal feeding or feeding by gastrostomy, and followed-up closely. Small perforation can heal after a period of time by nasal feeding, while tracheoesophageal fistula was needed to repaire after a period of time for restoring a good physical condition in most cases.

0.05). But according to the data, IL-8 in Qingqinye low dosage group was lower than model group, positive medicine group, Qingqinye high dosage group and Qingqinye middle dosage group. TNF-? in Qingqinye group was lower than model group and positive medicine group, especially in Qingqinye middle dosage group. Pathological section with articular cavity and surrounding tissues were better in positive medicine group and Qingqinye group. Conclusion Qingqinye has a certain effect for repairing joint immune pathological injury in hyperuricemia model rats.

Objective: To study the anti-tumor effect of recombinant human MUC1-MBP. Methods: The C57BL/6 mice were in oculated with MUC1-MBP by subcutaneous. MUC1 specific CTL activity of spleen were determined by MTT; The effects on prevention and treatment of tumor were observed by establishing lewis lung cancer-carrying mice. Results: The cytotoxicity of CTL from immunized mice to the MCF7 and Lewis lung cancer cells respectively was (47.7?4.3) % and (67.5 ?6.5) %; 5?10 5 lewis lung cancer cells following immunization were injected iv into C57BL/6 mice, after three weeks, the number of lung and tail tumor colonies was 51 and 5 for PBS and MUC1-MBP groups respectively and the suvival time was significantly delayed in immunized mice. The average volume of tumors in mice with MUC1-MBP was 386 mm 3 wherea control group was 4 000 mm 3 at tumor treating experiment. Conclusions: Recombinant human MUC1-MBP have significantly effects on prevention, treatment and inhibiting metastases of tumor. Our results suggested that the recombinant MUC1-MBP might be used to develop protein vaccine against human carcinoma.

Objective To develop a method for the determination of four saponins of panax notoginseng in Compound Dan-shen Prescription (CDP) by HPLC. Methods The conditions for the experiment were: determination of notoginsenoside R1, ginsenoside Rg1 and ginsenoside Re with acetonitrile - 0. 05 % phosphoric acid (19 : 81) as mobile phase and the detection wave at 203nm, determination of ginsenoside Rb1 with acetonitrile - water (33 : 67) as mobile phase and the detection wave at 203nm. Results A good linearity for notoginsenoside R1 was in the range of 0. 24 ~ 3. 6?g ( r = 0. 9997), 1. 2 ~ 18?g (r = 0. 9994) for ginsenoside Rg1, 0. 08 ~ 1. 2?g(r = 0. 9997) for ginsenoside Re and 0. 25-3. 72?g (r = 0. 9998) for ginsenoside Rb1. The stability of the four saponins is well kept at 4℃ for four months. Conclusion This method is simple, rapid, accurate and with good reproducibility and can be used for the quality control of CDP.

Objective:To establish an evaluation index system for training effect of order-oriented clinical medical students in Xinjiang by employers, so as to lay a foundation for training effect evaluation.Methods:On the basis of questionnaires and interviews with the training requirements of employers, Delphi method was used to determine the index system and weight.Results:The training requirements of employing units for the ability of free and directional medical students in autonomous regions were in turn competent for work, knowledge and practical ability, and good moral quality. The cultivation requirements for students' personal qualities of free and directional medical students were good interpersonal communication and moral quality. After three rounds of Delphi expert consultation, the evaluation index system was established, and three dimensions (knowledge, professional ability, professional ethics literacy), nine secondary indicators and 33 tertiary indicators were screened out, and the weights were determined.Conclusion:The evaluation index of training effect of directional clinical medical students established by Delphi expert consultation method needs further validation. Through the follow-up empirical application in directional clinical students, the evaluation index system can be constantly improved, which can also provide reference for the establishment of evaluation index system for other positions.
