Venous valve plays an important role in regulating the venous flow,especially in preventing the blood backflow.It has heen observed that when deep vein thrombosis and dissolved,the valves in the lesions had been destroied or dysfunction.The mechanism of damage of vein valve has not been fully clarified,but as we know,it's common that the inflammatory reaction,due to many unfavorable factors,can cause thrombosis.On the other hand,deep vein thrombosis could bring out the inflammatory reaction as well.So the author will review the development of researching of the destruction of venous valves in recent years.

Many epidemiological data and study of experiment show that adminstration of NSAIDs in long term can prevent the carcinogenesis of colorectal cancer, its mecanism can be associated with the inhibition of PG which is produced by Cox 2 way, in addition, promoting apoptosis and anti oxidation were also one of the mecanisms of NSAIDs, the new selective Cox 2 inhibitor without gastrointestinal side effect would become the chemopreventive drugs of colorectal tumor.

? Diabetic retinopathy is one of those significant complications of diabetes.With the increasing number of diabetic patients, blind caused by diabetic retinopathy is a serious threat to human health which cannot be neglected, but there is no highly effective treatment for it. Consequently, early detection and preventive treatment for it are important.Currently, studies have found that urine microalbumin had a close relation with diabetic retinopathy and that urine microalbumin might play an important role in early predicting of diabetic retinopathy. The review is about the diagnostic significance of urine microalbumin test for early diabetic retinopathy.

The cancer stem cell hypothesis posits that cancer stem cells,which are rare among the tumor cell population and share many common properties with normal stem cells,and have been positively identified and successfully isolated from some cancers,are responsible for tumorigenesis and implicated in multistage cancer progression,particularly with respect to metastasis.A better understanding may provide insights into the development of cancer stem cell-targeting therapeutic strategies.The examines what is known regarding cancer stem cells' concept,comparison with normal stem cell,potential origins,assays for isolation and their roles in metastasis.

Objective To evaluate the efficacy and safety of deoxyribonucleotide natrium in the treatment of secondary pulmonary tuberculosis.Methods A total of 94 cases with secondary pulmonary tuberculosis included in this study were dividing into control group and experiment group with each 47 cases.The patients in the both groups were give regular treatment.Patients in the control group were given standard chemotherapy regimen 3HRES/3HRE and patients in the experiment group revieved sodium deoxyribonucleotide injection 150mL+5％injection of liquid glucose 250mL by intravenous drip with once a day.1 time/d,two groups of patients with a cycle of 28d,a total of one cycles of treatment.The clinical efficacy,CA125,CA199,function of liver and kidney,occurrence of adverse reactions were compared between the two groups.Results The clinical efficacy in experiment group was 94.44％,which significant higher than that in control group 75.00％(P<0.05).The serum level of CA125 and CA199 decreased after treatment with experiment group much lower than the control group(P<0.05).Compared with the control group,the ALT,AST,Cr and serum BUN levels before and after treatment,the difference was not statistically significant.The adverse drug reactions was not statistically different between the two groups.Conclusion Deoxyribonucleotide natrium in the treatment of secondary pulmonary tuberculosis was effective with high safety.

Along with the quickly popularization of Internet, the literature resource sharing mode in library has been changed. The paper introduces the current development of it, including interlibrary loan, document delivery, IC card service, proposes shortcomings and ideas for the further development of literature resource sharing.

Operation is one of the important ways in breast cancer treatment.With the deep basic medical research,new theory,new concept and new technology improve the operation therapy in breast cancer in more scientific and rational way Breast-conserving therapy and sentinel lymph node bipsy (SLNB) are applied,and the neoadjuvant chemotherapy make breast-conserving therapy more feasible.The progress of operation therapy in breast cancer make it critical to emphasize the individualized treatment in breast cancer.

Objective To compare the current therapeutic effects between endovenous radiofrequency treatment and conventional surgery for lower limb chronic venous insufficiency (CVI) ,and summarize operative skills and clinical value of endovenous radiofreq uency treatment on CVI .Methods Data of 45 limbs of 41 patients treated by endovenous radiofrequency treatment (endovenous ra-diofrequencytreatmentgroup)and20limbsof20patientsbytraditionalsurgery(traditionalsurgerygroup)wereanalyzedandcom-pared in terms of operation time ,postoperative pain ,postoperative hospitalized duration ,complications ,and one-year recurrence rate .Results Endovenous radiofrequency treatment group had less postoperative pain and shorter postoperarive hospitalized dura-tion than traditional surgery group(P<0 .05) .The operation time had no significant differences between two groups (P>0 .05) . The two groups had few complications and had no recurrence in one year .Conclusion As a minimally invasive treatment for vari-cose veins ,endovenous radiofrequency treatment has less trauma ,rapid recovery ,safe and effective ,and it is worthy to be recommen-ded .
