Lymphatic metastasis is one of the main routes of tumor metastasis. The limitation of traditional medicine in the treatment of lymphatic tumor metastasis lies in the low concentration of the drug in lymphatic metastases resulting in poor efficacy. Nanocarrier-based drug delivery system plays an important role in enhancing drug targeting, improving drug bioavailability, and reducing side effects. This review introduces the composition and function of the lymphatic system as well as its role in tumor metastasis, enumerates the present therapeutic means and limitations of anti-tumor lymphatic metastasis, and focuses on the recent advances in the passive, active and antigen-presenting cell-mediated lymphatic targeted drug delivery systems in tumor metastasis are highlighted.

Objective To investigate the effect of edaravone pretreatment on myocardial injury induced by carbon dioxide pneumoperitoneum in patients undergoing laparoscopic gynecologic surgery.Methods Thirty patients undergoing laparoscopic gynecologic surgery,ASA Ⅰ or Ⅱ grade,were divided into two groups by random digits table with 15 cases each:control group and edaravone group.Edaravone group following tracheal intubation received vein infusion of edaravone 0.5 mg/kg,control group received equal volume of 0.9％ sodium chloride.The carbon dioxide pneumoperitoneum pressure was maintained at 10-15 mm Hg (1 mm Hg =0.133 kPa).Venous blood samples were collected before anesthesia induction and after operation 8 h for the measurement of the serum creatine kinase (CK),creatine kinase-MB (CK-MB),aspartate aminotransferase (AST) and lactate dehydrogenase (LDH).Results The serum levels of CK and AST were significantly higher after operation 8 h in control group than those of before anesthesia induction in control group and after operation 8 h in edaravone group [(205 ± 27) U/L vs.(123 ± 25) and (123 ± 29)U/L,(48±5) U/L vs.(34 ±3) and (36 ±5) U/L,P＜0.05].There was no significant difference in the serum levels of CK-MB and LDH between two groups and the group (P ＞ 0.05).Conclusion Pretreatment with edaravone 0.5 mg/kg can protect myocardium in patients undergoing laparoscopic gynecologic surgery.

Objective To observe the recent clinical efficacy of the sequential therapy hormone in the treatment of active rheumatoid arthritis.Methods In accordance with the principle of digital sheet,160 patients with active rheumatoid arthritis were randomly divided into the observation group and the control group,80 cases in each group.On the basis of methotrexate and leflunomide in both groups,the hormone sequential therapy was given in the observation group,but prednisone was given in the control group.The clinical efficacy of treatment after 1 week and 3 months were compared in two groups.Results In the observation group,the indicators in 7 d after treatment were significantly reduced,compared with untreated(t =19.90,7.63,14.73,7.58,6.84,14.09,all P ＜0.01),In the control group,three indicators of the duration of morning stiffness,joint tenderness index and joint swelling index in 7d after treatment were significantly reduced,compared with untreated (t =13.42,3.34,7.24,all P ＜ 0.01),Compared the indicators in the two groups in 7 d after treatment,there were statistically significant differences (t =13.07,4.92,10.51,5.23,5.74,15.03,all P ＜ 0.01).The indicators in the 3 months after treatment in both groups were signifi cantly decreased,buttherewasnosignificantdifferencebetweenthetwogroups (t =1.80,1.73,1.59,1.22,1.21,1.35,all P ＞ 0.05).The total effective rate was 80% in the observation group; but the rate was 75 % in the control group;there was no statistically significant difference in the two groups(x2 =0.57,P ＞ 0.05).Conclusion The sequential hormone therapy is an effective means for the treatment of active rheumatoid arthritis,by controlled the symptoms of rheumatoid arthritis effectively and alleviated the patient's condition.

BACKGROUND: The study of isolation, purification, culture, cell labeling, inducing factors, effects of gene transfection on cytobiology, cell carrier construction, and time window for back transplantation of cell compound pertaining to marrow stromal cells (MSCs) is still in its infancy. OBJECTIVE: To search for an in vitro culture method that can be simply and effectively obtained. DESIGN, TIME AND SETTING: The present cytological in vitro experiment was performed at the Beijing Institute of Genome, Chinese Academy of Sciences between June 2006 and July 2007. MATERIALS: Eight specific pathogen-free New Zealand rabbits, aged 6 weeks, were provided by the Laboratory Animal Center, Institute of Genetics and Development, Chinese Academy of Sciences. METHODS: Under sterile condition, 1 mL rabbit bone marrow was taken and diluted with D-Hanks solution. Following centrifugation and subsequent supernatant removal, bone marrow was re-suspended using dulbecco's modified eagle's medium (DMEM) for single cell suspension. Next, single cell suspension was dropped onto the liquid surface of equal-volume lymphocyte separation medium (density: 1.077). Subsequent to centrifugation, cloudlike mononuclear cell layer was collected and re-suspended with DMEM containing 20% fetal bovine serum. The cells were inoculated at lxl0/cm2 and purified by adherent method. When 70%-80% of flask bottom was covered, cell digestion and passage was performed.MAIN OUTCOME MEASURES: Cell growth was observed with an operating microscope. Surviving cells were counted by Trypan blue viability test. Cell identification was performed by hematoxylin-eosin staining. Through the use of 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay, cell viability was detected to observe the cellular resuscitation of the cultured cells following cryopreservation. RESULTS: Twenty-four hours after inoculation, cells began to adhere to the wall, exhibiting short shuttle- or triangle-shaped appearance with different sizes of cellular processes. Three days later, adherent cells began to divide, and cell clusters could be found in some areas; One week later, most of cells exhibited scattered fibroblast-like growth; After passage, cells were evenly distributed with long shuttle-shaped appearance and arranged orderly. Following 3 passages, there wound be 5×106-1×107 adherent cells in 1 mL MSC suspension. Approximately 90% of MSCs survived and identified as mononuclear cells. Cells vigorously grew at days 1-6 after inoculation and reached a peak level at day 8, followed by a viability decline. After 56 days of resuscitation, frozen cells displayed a good and rapid growth. CONCLUSION: Highly purified MSCs can be acquired by gradient centrifugation of lymphocyte separation medium. Enough seeded cells can be obtained by in vitro culture and the cellular viability does not change after frozen preservation and resuscitation.
