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.

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.

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.

AIM: To approach the best therapeutic measures after allochthonous intermingled with autogenous bone transplantation in children with tumor-like legion. METHODS: Forty children received bone transplantation between from March 2003 to March 2006 were selected from First Hospital Affiliated to Zhengzhou University. The guardians of Children all knew and agreed with the items. Subjects were divided into two groups according to the bone grafts with 20 children in each group: Compound transplantation group and autoplastic transplantation group. ① Subjects in compound transplantation group were transplanted with compound bone of allochthonous bone, autogenous bone and marrow with 160 thousands of gentamicin, 400 mg of vacocin and 5 mg of dexamethasone added. Allochthonous bone was obtained from dried radiosteriliaed bone, which was made by Shanxi Aorui Biomaterial Co., Ltd. Autogenous bone was gotten from the iliac bone of children. ② Subjects in autoplastic transplantation group were transplanted with simple illac bone got from subjects. Meanwhile, 16 thousands of gentamycin was adopted in the transplantation without using dexamethasone. ③ 5 mg of dexamethasone was added in to the allochthonous bone used for the surgery of subjects in compound transplantation group, and intervenous drop infusion of hormone was given to subjects after the surgery at proper dose, while children in autoplastic transplantation group received no hormone during and after the surgery. ④ Post-operation draining was performed, and the draining flow within 24 hours less than 20 mL was taken as the index of extubate. ⑤ The allochthonous bone and autoplastic bone were immersed into 160 thousands of gentamicin and 400 mg of norvancomycin used for patients in the compound transplantation group. Patients in both groups were administrated with antibiotic drugs of blue mold for fear of infection. ⑥ The duration of recovery to normal body temperature, leukocyte count and erythrocyte sedimentation rate (ESR) as well as the time of reservation of drainage tube of patients in both groups were observed after the surgery after operation, and follow-up was conducted regularly. RESULTS: Totally 40 patients were involved in the analysis of results, and no one withdrew from the study. ① The duration of recovery to normal body temperature, leukocyte count and ESR as well as the time of reservation of drainage tube of patients in compound transplantation group were longer than those in autoplastic group [(10.95?2.63,13.85?2.68,25.90?2.53,13.15?3.01) days;(6.95?1.57,8.80?1.96,15.30?2.27,6.40?1.98) days,P

Infection of Entamoeba histolytica with chytridiaceous fungus Sphaerlta was observed in some specimens obtained from a farmer and stained with iron-haematoxylin. The fungi were found in 78% of tne cysts, mostly immature ones. Within the amoebae this parasite occurred singly, in groups, or in the form of a sporangium. It was located in the cytoplasm, the glycogen mass or the chromatoidal bars.In the same specimen, the parasitic fungus was also found in 18% of E. coli cysts; in 11% of E. nana cysts; while only one of 16 E. hartmanni cysts was parasitized.It is an interesting case of superimposed parasitism so far reported in China as well as a rare rase of several species of amoebae being heavily involved with the same in the scientific literarure.

[Objective]To observe clinical value of multi-slice spiral X-ray computed tomography(MSCT)volume rendering technique(VRT)and multi-planar reconstruction(MPR)in classification and treatment of tibial plateau fracture(TPF).[Method]From August 2005 to February 2009,49 fratures in 45 patients with TPF were treated.Their clinical data were studied retrospectively.There were 32 males and 13 females.The patients were aged from 20-65 years(mean 46 years).Four patients suffered bilateral TPF.All patients were examined with standard X-rays and 64-slice spiral CT scanner.Axial CT scans were processed with VRT and MPR.Their X-ray plain films and 64-slice spiral CT seans(including VRT and MPR)were performed to determine their fracture types and protocol.[Result]According to the VRT and MPR findings,13 fractures(13/49)classified by X-ray plain film were corrected,protocols were changed for 9 fractures(9/49),and 15 fractures(46.9%)of intereondylar eminence of the tibia and 6 fractures(28.6%)of proximal fibula were underdiagnozed.[Conclusion]MSCT(VRT+MPR)can clearly show the area and degree of tibial plateau collapse,the details of TPF and the delitescence fracture,help to determine TPF types,decrease the underdiagnosis rate and choose a rational protocol.The use of combined VRT and MPR is a supplementary means for X-ray plain film and axial CT scanning.which has great clinical value.

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.

[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.
