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.

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.

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 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.

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.

The normal value of parameters of saccade, smooth pursuit and optokinetic nystagmus has been detected by recording the electro-oculograph in 29 healthy subjects.The results are as follows: 1.The reaction time of saccade is 259.04? 74.19,the mean velocity is 216.83?87.51/s in 15? target amplitude.No statistical significance has been found between sexes, but the reaction time is obviously longer in pre-puberty group.2.For smooth pursuit in 40% target velocity, gain is 0.976?0.08, phase lag is 3.95?7.69s,moothness is 0.925?1.49.No statistical significance has been found between sexes.3.In analysing the sequential process of saccade and smooth pursuit, it can't observed the tendency of decrement in latency.4.The gain of OKN in 14?/s velocity is between 0.689-0.808, the gain decreases following the increase of target velocity.The symmetry of OKN is 3.54?15.04% and there are 81.58% of OKN belonging macula type in healthy people.5.When the target velocity is in close each other,the velocity of fast phase of OKN is in close with the velocity of saccade.

Eight cases of human rabies encephalomyelitis confirmed by autopsy were reported. They all had a history of rabid dog bite and typical clinical manifestations of rabies. The mean clinical course ran about 4 days. The most frequent pathological findings were the appearence of intracytoplasmic Negri bodies in neuron and paren-chymal inflammation of the brain and spinal cord. The inflammatory response was more prominent in the brainstem, hippocampus and spinal cord, consisting of peri-vascular cuffs of lymphocytes and monocytes, foci of softening microglial response and neuronophagia. Negri bodies were found in all of the sections taken from the brain, especially frequently found in the purkinjs cells of the cerebsll um and the pyramidal cells of the hippocampi in all the eight cases.The pathodiagnostic principles of this disease, and its differentiation from type B encephalitis and polimyelitis were briefly discussed. The relation between the site of the dog bite and the distribution of the lesions and the duration of the incubation period were also discussed.

Objective To study the relationship between polyps of middle meatus and the position of the inferior border of the middle concha related to the semilunar hiatus, and to evaluate the diagnostic value of coronal CT scan of the nasal cavity after ephedrine spray by means of comparison of CT images and clinical findings Methods The coronal CT studys of 102 cases clinically suspected as sinusitis and/or nasal polyps were included in this study 1% ephedrine was sprayed in nasal cavity of the patients before CT study and the patient were asked to take supine position with head over extended over 5 minutes Axial and coronal CT scan was taken with supine position, 2 mm slice thickness and high resolution reconstruction Observation was focused on contraction of the nasal mucosa and soft tissue mass of the middle meatus (polyps) The middle concha was divided into 3 types according the position of its inferior border related to the semilunar hiatus: superior hiatus type (the inferior border of the middle concha superior to the semilunar hiatus), hiatus type (the inferior edge of the middle concha at the level of the semilunar hiatus), inferior hiatus type (the inferior edge of the middle concha inferior to the semilunar hiatus) Statistic comparing the occurrence of the middle meatus polyps with different middle conchas type and measuring the length of the middle conchas of inferior hiatus type from the level of the semilunar hiatus to the inferior border were performad Results Good and better contraction of the nasal mucosa with clear manifestation of the lesion was seen in 98 of 102 cases Nasal polyps of middle meatus were diagnosed in 71 sides of nasal cavities of 47 cases and confirmed surgically and/or clinically 39 superior hiatus and hiatus middle conchas were found ipsilateral to the polyps (54 9%) Of 204 sides of 102 cases, superior hiatus type middle conchas was found in 18 sides of nasal cavity with middle meatus polyps in 11 sides (61 1%); hiatus type in 38 sides with middle meatus polys in 28 sides (73 7%); and inferior hiatus type in 148 sides with middle meatus polys in 32 sides (21 6%) The difference was markedly significant statistically Conclusion Coronal CT scan after ephedrine spray into the nasal cavity can depict the mass in the nasal cavity better, especially nasal polyps with swollen mucosa The method is simple and easy to perform The poorly developed middle concha and the exposed middle meatus may be one of the causes of polyps of middle meatus It clues on that the middle concha should be preserved as much as possible during the endoscopic sinus surgery, opening the ethmoidal infundibulum and bullas, to decrease post operative recurrence of middle meatus polyps
