Midkine (MK),a member of the heparin-binding growth factors,was firstly discovered in mouse embryonic carcinoma cells by Japanese scholars.MK functions in a variety of biological processes,including neurogenesis,activation of plasminogen activator,wound tissue repair and inflammatory response.More importantly,MK is closely related to tumor progress and metastasis.Current studies show that MK is over-expressed in various human malignant tumors,making it as a promising tumor biomarker and possibly a new molecular target for tumor therapy.This review will illustrate the molecular structure and functional mechanisms of MK,as well as its roles in the diagnosis,progression monitoring and prognosis prediction of colorectal cancer.

Objective:To explore the role of the inpatient education platform of internet plus 317 nursing that was assistant of health education of nurse in the clinical nursing work.Method: 100 patients with orthopedic disease were divided into observation group (50 cases)and control group (50 cases) as random number table. The patients of observation group received admission education and health education by using internet plus 317 nursing, which was assistant of health education of nurse, while the patients of control group received routine education mode including dictate of cramming mode, blackboard newspaper, propaganda handbook and telephone follow-up and so on. And then the score of anxiety self-assessment scale (SAS) and nursing satisfaction degree between the two groups were compared and analyzed.Result: The scores of SAS of observation group in admission and 7 d later were (49.66±9.126) points and (46.32±7.02) points, respectively, and the scores of them of control group respectively were (48.18±9.260) points and (45.22±6.53) points. And the differences between the two time point in each group were not statistically significant (t=0.805.81,t=0.812,P>0.05). At discharge, the score of observation group (39.08±3.59) points was significantly lower than that of control group (42.86±4.25) points (t=4.81,P<0.05). Besides, the satisfaction degree of observation group was significantly better than that of control group(x2=0.925, P=0.031).Conclusion: The inpatient education platform of internet plus 317 nursing can guide health of patients in time, and quickly solve problems during hospitalization, and reduce the SAS score of patients, and increase the patient's satisfaction degree for clinical nursing quality.

[Objective]To evaluate the surgical management and its results of type A fractures of distal humerus in children utilized with double tension hands(DTB).[Method]From January 1999 to May 2005,52 patients of type A fractures of distal humerus in children were treated surgically through approach of DTB.Seven patients suffered open fractures(Gustilo scale Ⅰ in 5,and Ⅱ in 2).Fourty-five patients suffered closed fractures.According to AO/ASIF classification,type A2 fracture was found in 41 cases and type A3 in 11 cases.The elbows were flexed to 90?and immobilized with long-arm casts for 2 weeks.The rehabilitation exercises began at 2～3 weeks post-operatively.[Result]All the patients were followed up,with the duration from 6 to 18 months(averaged,12.5 months).All the fractures were healed,no cubitus varus deformity.The function of the elbow was evaluated according to Flynnet's scale,the results showed excellent in 41 cases,good in 10cases,and poor in 1 case.[Conclusion]The use of DTB for the surgical management of type A fractures of distal humerus in children has many advantages,it provides a new sufficient internal fixation with simple technical procedure,anatomical reduction under direct vision,reliablestability,facilitates rehabilitation exercises and low complication rate.DTB is a better choice in treatment of type A fractures of distal humerus in children.

[Objective]To explore the surgical technique and clinical results of minimally invasive incision dynamic hip screws (DHS) in treatment of intertrochanteric fractures in the elderly.[Method]From August 2001 to January 2006,37 old cases (15 males and 22 females, aged from 72 years to 92 years, mean 81.5 years) with intertrochanteric fractures were treated with closed reduction and DHS using minimally invasive technique in our hospital. The procedure included following and critical steps:1～2 k-wires was inserted into the upper part of the femoral head through great trochanter percutaneously after operation. A guide wire was inserted into the center of the femoral head according to 135? collodiaphyseal angle; then, a small incision (4～5.5 cm) was made and along the guide wire for inserting a screw into the femoral head. The guide wire was removed and the side plate was slipped under the soft tissue into to tightly contact the lateral surface of femur, and followed by the side plate barrel being seated on the screw.[Result]The operation time was 40～75 minutes (average 60 minutes) The mean amount of blood loss in, operation was 55 ml. The mean amount of hemoaleh:in showed no significant difference between postoperation and preoperation. The following-up period averaged 15 months (11～18 months) The clinical hone healing lasted for 10～15 weeks. Two cases had mild coxa vara, there were no incision infection, fixation failure or lower extremity rotatory deformity. The excellent rate of joint function was 94.6% according to DONG's assay standard. [Conclusion]Minimally invasive incision DHS has the advantages of shorter operation time, less blood loss, little trauma, less complications and quick functional recovery and is an effective and safe method for treatment of femoral intertrochanteric fractures in the elderly.

[Objective]To evaluate the clinical characteristics and effect of operative treatment for the ossification of ligamentum flavum thoracic spinal stenosis (OLF-TSS). [Methods]From October 1998 to February 2007,38 patients with OLF-TSS were treated with en bloc hemi-articular process laminectomy. In this group,25 cases were male,and 13 cases were female. The average age was 48 years (range,29～71 years). Totally 81.6% of the lesion was between T10～L1 intervertebral disc space.The average history was 10 months. There were 5.3 percent with protrusion of intervertebral disc of thoracio spine.[Results]Thirty-eight cases were followed-up for 1～8 years,with an average of 3 years and 6 months. Dural injury occurred in 4 cases of 38,3 cases appeared postoperative cerebrospinal fluid leakage. All cases were cured conservatively mainly with bed rest in the prostrate position. According to WANG's evaluation,25 had excellent results,11 had good results,2 had no change and none was poor,The excellent to good rate was 94.7% in this group. There were no patients with the wrong level. No patient neurological functions were deteriorated.[Conclusion]The chinical features of OLF-TSS are very complex. The common symptoms of the disease are progressive onset of numbness,weakness,low back pain,intermittent claudication of the lower extremities,constriction on trunk or lower limbs and sphincter dysfunction. The clinical presentation and neurological examination associated with X-ray film,MRI and CT were the important means of the diagnosis of the disease. Removal of the posterior wall of the thoracic spinal canal via the technique of en bloc hemi-articular process laminectomy is safe and effective to treat OLF-TSS. The strategy for diminishing fault and complications is to discriminate pathogenic segment (locating-diagnosis) and follow the principles of surgical procedure.
