1.The role of intraoperatve radiotherapy in the management of breast cancer
China Oncology 2013;(8):590-595
Breast cancer is the most common disease in women worldwide, which not only threatened the women’s survival time, but also inlfuenced their quality of life as well. Within this challenge, it’s important to optimize the current multidisciplinary treatment stratagem for breast cancer. Radiotherapy is one of the most important treatment modality for patients with breast cancer, with the trend to shrink the irradiated volume and shorten the total fraction times in recent years. Intraoperative radiation therapy (IORT) as a fast and convenient procedure has the ability to deliver a high, single-fraction radiation dose to tumor beds with minimal exposure of surrounding tissues (lung, heart, etc.), which could be displaced or shielded right after the tumor removal during the surgical procedure. Right now, IORT has been either integrated as a boost technique in multimodal approaches using postoperative EBRT in the treatment of early breast cancer patients undergoing breast conservation surgery or used as a single dose accelerated partial breast irradiation technique for these patients. This review discussed the rationale of IORT, the beneifts and limitations of IORT, the indication and the clinical results of this procedure, including treatment related side-effects as well in order to provide the preliminary evidence based approach for early breast cancer patients.
2.New areas of laboratory medicine in the 21st century:terahertz laboratory medicine
Chinese Journal of Laboratory Medicine 2015;38(1):1-3
The terahertz laboratory medicine (THz-LabMed) is an intergrated cross-frontier field which involves multi-disciplinary including medicine,biology,biomedical engineering,physics,optics,computer science,information and materials.Using THz technologies for label-free detection and analysis of biomedical macromolecules,cell and tissues,the THz-LabMed is also the core components of terahertz biomedine (THz-BioMed) which focuses on the biomedical application of THz technologies.THz label-free detection is being paid more and more attention because of its unique advantages worldwide and becomes a hot spot for the application of THz wave technology and methods in life science.Application of THz technology in biomedicine involves many fields globally,including disease diagnosis,recognition of protein status,label-free DNA sequencing,mechanism for absorption differences of biological tissue to THz wave,and radiation influence on biological samples and biological process.THz-LabMed is the global synchronized research in THz-BioMed field in China.It is important to seize the opportunities to develop new disciplines of laboratory medicine.

Egr-1 is an important transcription factor, which regulates at least 30 kinds of gene expression. Egr-1 couples extracellular signals to long-term responses by altering expression of Egr-1 target genes. So egr-1 can directly or indirectly affect cell differentiation,apoptosis,immune response,injury and repair. This article reviewed the progress in Egr-1 and the lung disease.

Objective To map the complete methylation status of the hMLH1 promoter in sporadic colorectal carcinoma and analyze the relationship between MVPs (methylation variable positions) of hMLH1 promoter and the expression of hMLH1. Methods Methylation status of hMLH1 promoter was measured by bisulfite sequencing. hMLH1 protein expression was detected by immunohistochemistry. Results Out of the 30 sporadic colorectal carcinoma specimens, the hypermethylation of CGIs (CpG islands) 1 was in 6 and that of CGIs 2 in 4. The hMLH1 protein was detected in 15 specimens. Chi square test showed the methylation of CGIs 1 was closely related to loss of hMLH1 protein expression (P0.05). Conclusion In CGIs 1, CpG positions from 1 to 28 are the critical region that could influence the expression of hMLH1.

OBJECTIVE: To investigate the use of antibiotics in our hospital. METHODS: All the prescriptions in Jan., Apr., July and Oct. in 2006 in dispensary for western medicine were reviewed, from which, 6 605 (17.26%) antibiotic prescriptions were selected. The categories and kinds of antibiotics were investigated; meanwhile the administration and dosage, course of treatment and drug combination were analyzed based on diagnosis and patient's age. RESULTS: The antibiotics used in 6 605 prescriptions totaled 7 categories. 87.80% used antibacterial drugs accorded with diagnose; 56.46% of the antibacterial drugs were administered orally; in terms of dosage and administration, more than 95% were up to the standard; the course of treatment in 86.99% ranged from 3 to 7 days; 91.04% of the antibacterial drugs used in single kind, about 8.80% in two kinds, and only 0.17% in three kinds concomitantly. CONCLUSION: The use of antibacterial drugs in our hospital is rational on the whole, yet it is far from perfect. Measures should be taken to further improve the rational drug use level.
