The callus of a "Luling"strain of Plantago asiatica was induced by 2, 4-D. When the induced callus was transferred to 2, 4-D free MS medium,budgensis was observed about 2 weeks afterward only by the addition of 6-BA alone. Rootgensis of the bud was stimulated by NAA and 6-BA added to the MS medium thereafter.Finally, the completed plantlet could be obtained.

Many accessories to the ventilator such as the humidifier and the artificial nose are widely used and applied. In clinical medicine engineering, doctors and medical engineers have to be integrated to perform patient-centered care and to accomplish the functional structure based on the patient's essential physiological indexes. The scientific quality control has to be implemented during the operation, maintenance and sterilization of the equipment, thus iatrogenic infection can be avoided and medical diagnosis and treatment can be enhanced.

After enlarging student's enrollment in college,the great change of education and teaching situation took place.In order to improve the teaching quality in medical college,some problems in experiment teaching and their countermeasures were put forward in this paper,such as the experimental kinds and methods of experiment,the arrangement of experiment classes,the fitting out and the use of equipment as well as the modern education techniques and experiment education,etc.

OBJECTIVETo compare five materials commonly used in dentistry, including three types of metals and two types of ceramics, by using different sequences of three magnetic resonance imaging (MRI) field strengths (0.35, 1.5, and 3.0 T).

METHODSThree types of metals and two types of ceramics that were fabricated into the same size and thickness as an incisor crown were placed in a plastic tank filled with saline. The crowns were scanned using an magnetic resonance (MR) machine at 0.35, 1.5, and 3.0 T field strengths. The TlWI and T2WI images were obtained. The differences of various materials in different artifacts of field MR scans were determined.

RESULTSThe zirconia crown presented no significant artifacts when scanned under the three types of MRI field strengths. The artifacts of casting ceramic were minimal. All dental precious metal alloys, nickel-chromium alloy dental porcelain, and cobalt-chromium ceramic alloy showed varying degrees of artifacts under the three MRI field strengths.

CONCLUSIONZirconia and casting ceramics present almost no or faint artifacts. By contrast, precious metal alloys, nickel-chromium alloy dental porcelain and cobalt-chromium ceramic alloy display MRI artifacts. The artifact area increase with increasing magnetic field.

In recent years,some aspects of the standardized resection of colon cancer,metastases,recurrent tumor therapy and laparoscopic applications have new concepts.In particular,the view of complete mesocolic excision(CME) is more scientific and effective from the level of embryonic development and anatomy,which lays the foundation for controlling the quality of colon surgery.

BACKGROUND:At present, occlusion of the drainage tube was commonly used to reduce the drainage volume after total hip arthroplasty so as to promote the incision healing and hip function rehabilitation. However, the occlusion time is a problem deserving further investigations. OBJECTIVE:To research the effects of temporarily clamping drainage tube on drainage volume in early stage after total hip arthroplasty. METHODS:From January to October 2013, 112 patients received unilateral total hip arthroplasty in the First Ward, Department of Orthopedics, First Affiliated Hospital, Zhengzhou University in China. They were randomly divided into four groups according to the admission time (n=28):occlusion of the drainage tube for 2, 4 and 6 hours and without occlusion of the drainage tube. Al tubes were pul ed out in postoperative 48 hours. Moreover, 48-hour postoperative hemoglobin and drainage volume, the healing of incision and the score of hip joint function when patients were fol owed up at 1.5 months postoperatively were recorded accurately. RESULTS AND CONCLUSION:48-hour hemoglobin drop level and 48-hour incision drainage volume were highest in the non-occlusion group, fol owed by 2-hour occlusion group, 4-hour occlusion group and 6-hour occlusion group (P<0.05). However, no significant differences in the healing time of postoperative incision and the Harris score of hip joint function when patients were fol owed up at 1.5 months postoperatively were detected among groups (P>0.05). Incision infection and tension split were not seen in each group. Six cases affected subcutaneous ecchymosis and swel ing accompanied by pain and four cases suffered from the venous plexus thrombosis of the calf muscle in the 6-hour occlusion group. One case experienced fat liquefaction separately in the 4-hour occlusion group and non-occlusion group. These results suggested that temporary occlusion of the drainage tube in the early stage of total hip arthroplasty could reduce the drainage volume of incision. The suitable time of clamping drainage tube was 4 hours, and there were no adverse effects on healing of incision and recovery of hip function.

[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.
