Circulating tumor cells (CTCs)are special kind of tumor cells in the peripheral blood of patient with tumor.Now CTCs detection has been used in the survival time prediction,post-operational recu-rrence detection,individualized treatment and other aspects in the patients with gastric cancer.As the research going,CTCs will provide new help for the comprehensive treatment of gastric cancer.

Purpose: To study the immunophenotype and the expression of cytotoxic granule proteins of nasal NK/T cell lymphoma and its significance. Methods: 44 cases of nasal NK/T cell lymphoma were studied by the two-step method of DAKO EnVisionTM using a series of antibodies including CD3, CD20, CD43, CD45, CEI45RO, CD56, CD57, CD79?, TIA-1, granzyme-B and perform. Results: All the cases of nasal NK/T cell lymphoma were CD45 positive. 43% of the cases expressed CD3 with positive signal located in the cytoplasm, which was different from peripheral T cell lymphoma. 45% and 52% of the cases were CD43 and CD45RO positive respectively. Cases that reacted to CD56 accounted for 52% of the cases, 43% of which were also positive to CD3. Concerning the reactions to both CD3 and CD56, 10 cases showed CD3 + CD56 + , 13 showed CD3-CD56 + , 9 were CD3 + CD56- and 12 were CD3-CD56-. None of the 44 cases showed positive reaction to CD20, CD79? and CD57. All cases were reactive to TIA-1. 93% and 95% of the cases showed the reactions to granzyme-B and perform. All the controls were negative to TIA-1, granzyme-B and perform. Conclusions: The immunophenotypes of nasal NK/T cell lymphoma showed less consistency. CD56 was not always positive in the cases of this tumor. The different locations of the positive signal to CD3 showed that the cell lineage of this tumor was different from T lymphocytes. The high frequency of the staining by cytotoxic granule proteins, TIA-1, granzyme-B and perform, showed that these cells may have originated from NK cells. The distinctive differences in immunohistochemical staining of cytotoxic granule proteins in nasal NK/T cell lymphoma make their detection very useful and important in diagnosis and differential diagnosis.

Objective To study the biocompatibility of human hair keratin artificial tendon(HHKAT) material in vitro. Methods Human embryonic tendon cell (HETC) was incubated with various concentrations (100%,50%,10%) of extracted liquid of HHKAT material for 1,3,5 and 7 days, respectively. Collagen I expression in HETC was detected by immunocytochemistry. The effects of HHKAT material on the proliferation and ultrastructure of HETC were observed. Results Various concentrations of extracted liquid of HHKAT had no effect on the morphologic, collagen I expression and ultrastructure of HETC. HETC could adhere, grow and proliferate on the surface of HHKAT material. Conclusion HHKAT is a medical biomaterial with good biocompatibility in vitro.

Packing the nose after septoplasty is common practice. The use of postoperative packing has been proposed to reduce the dead space between the subperichondrial flaps and minimize postoperative complications such as hemorrhage, septal hematoma, and formation of synechiae. Additionally, postoperative packing is thought to stabilize the remaining cartilaginous septum and minimize persistence or recurrence of septal deviation. Despite these theoretic advantages, evidence to support the use of postoperative packing is lacking. Additionally, nasal packing is not an innocuous procedure. The use of nasal packing actually cause these complications such as postop- erative pain, mucosal injury, bleeding, worsening of breathing due to sleep disorders, and postoperative infections. Routine use of anterior nasal packing after septoplasty should be challenged for not presenting proven benefit. As alternatives to traditional packing, septal suturing, septal stapler and fibrin glue have been used recently. The purpose of this article is to summarize the progress of traditional packing to no packing after septoplasty.

Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

OBJECTIVE To promote the management of nosocomial infections continuous improvement in the clinical and medical technology department.METHODS According to the regulation of nosocomial infections management,a handbook of nosocomial infections management for clinical and medical technology department was designed,and the monitors of nosocomial infection could perform real time inspection and record according require of the handbook.The department of nosocomial infections management examined the monitoring work of clinical and medical technology department every month and summarized every year,and the results were internalized to the valuation of medical quality management.RESULTS After 3 years of the usage of the handbook,the capability of the monitor groups of nosocomial infection and the quality of the all monitoring items were significantly improved;the qualified rates were all above 96.30%.CONCLUSIONS The handbook of nosocomial infections management is useful to improve the quality of nosocomial infections management in the clinical and medical technology department.

Objective To determin and compare the significance of the expression of chemotactic cytokines in pleural effusions monocyte chemoattractant protein-1(MCP-1)and regulated on activation,normal,T-cell expressed and secreted(RANTES)levels in tuberculous and malignant pleural effusions.Methods The effusion and serum levels of MCP-1 and RANTES were measured in 37 patients with tuberculous pleural effusion and 35 patients with malignant pleural effusion,and selected 20 healthy people acting as control group.Results The effusion and serum levds of MCP-1 and RANTES in tuberculous effusion patients was significantly higher than that in malignant group(P＜0.01);In tuberculous group,the content of MCP-1 in serum was higher than control group,the serum level of RANTES was no statistic significant difference between control group and tuberculous group.The contents of MCP-1 and RANTES were not correlated with pathologic type of lung.cancer.Conclusion MCP-1 and RANTES technique has an important clinical value in diagnosis and differential diagnosis of tuberculosis and malignant pleural effusion.
