Physiological MR imaging techniques provide abundant information for the diagnosis and research of knee cartilage le -sions.It can not only evaluate the morphology and structure of cartilage , but also analyze the functional , metabolic and biochemical changes quantitatively , to explore the causes of cartilage lesions at the molecular level .Application and advance of physiological MR imaging of knee articular cartilage are reviewed , including sodium imaging , delayed gadolinium enhanced magnetic resonance imaging of cartilage, T1ρ, T2 mapping, chemical exchange saturation transfer , diffusion imaging and so on, aiming at providing references for choosing MR imaging of knee articular cartilage .

Objective To discuss the reliability of sensory integration curing and the affecting element of curing result. Method Adopt standardized curing method to 455 children, four to twelve years old, who have sensory integration disorder. Start up parents school as well. Result The total effective rate is 85%. The more parents grasp the children sanitation knowledge, the better results are. The better results are also related to the level of disorder, intelligence quotient, age and curing period. Conclusion Sensory integrating treatment is effective in treating sensory integrating disohter in children by systematic psychological intervention for children and personal psychological intervention for parents.

Two cases of left atrial myxoma were reported and the clinical data of 58 cases in Chinese literature were reviewed with the emphasis to find the characteristics of this disease on x-ray plain films and in the clinical features. The criteria to differentiate this condition from rheumatic mitral stenosis were listed. It is suggested that the diagnosis of left atrial myxoma be considered when the x-ray features of a clinically suspected case of mitral stenosis are not typical and then echocardiography be performed to investigate the case further.

On a left lateral chest radiogram,3 points are determined:A is the apex of the sternal angle formed by the manubrium and the body of the sternum,B is the highest point of the contact surface between the anterio-superior heart border and the anterior chest wall,and C is the apex of the anterior costophrenic angle.The distances of AC and BC are measured.The ratio of BC:AC is considered as an index of the size of the right ventricle.On the basis of measuring 120 normal subjects,0.54(0.46?0.04) is employed as the upper limit of normal values.Left lateral chest radiogram is easy to take.The measuring procedure is simple.The results of this measurement proves to be valuable after the method has been applied clinically.In the evaluation of the size of the right ventricle,this new digital index is helpful in the analysis of serial radiograms.This measurement makes left lateral chest radiogram more useful in detecting cardiac abnormalities.

The academic thoughts of WU Pei-heng originate from the theory of emphasizing yang in Inner Canon of Huangdi and warming and assisting yang theory in Treatise on Cold Pathogenic Diseases,which inherits and develops the theorectical essence of ZHENG Qin-an.The core of WU Pei-heng’s academic thoughts is the importance of yang-qi in human body.In his opinion,yang-qi is the essence of human,warming yang is the basic principle and treatment in clinic,large dose of aconite root should be used to saving critical patient.In addition,two cases treated by warming yang method are recorded to verify the practicability of WU Pei-heng’s thoughts.

Easily confusable seed of Ziziphus jujuba var. spinosa (Bunge ) Hu and Hovenia acerba Lindl., Allium tuberosum Rottl .ex spreng. and A. fistulosum; Sinapis alba L. and Brassica campestris L. were examined under scanning electron microscope. Results s howed that: 1. )irregular nests were present on the surface of semen Z. jujuba var. spinosa, while papillae appeared on the surface of senen H.acerba Lindl; 2. ) Cells of seed coat of semen A. tuberosum were irregularly shaped or polygonic with protruding cutin on its peridium, while that of Semen A. fistulcsum were polygonic with connecting fibers between cells; 3. ) cells of semen S.alba L. were similarily polygonic, with thick and protruding vertical perine,while that of semen B. campestris L. were also polygonic, but its vertical perine were thiner and less protruding, its peridium shrinked in side and was covered with cutinous nets veins.

This paper summarizes the progress in the study on anthelmintics,including nematocide,trematocide and cestocide since the founding of the People′ s Republic of China and the roles that these agents played in the control of parasitic diseases.Meanwhile,views are given to the challenges faced in the further study on anthelmintics.

Objective To observe the efficacy and complication of laser subepithelial keratom ileusis (LASEK) combined with mitomycin C (MMC) in treatment of high myopia.Methods 118 cases ( 236 eyes) diagnosed as high myopia were treated by LASEK combined with MMC.The changes of vision,refractive regression,postoperation pain and haze were observed.Results 7-days after operation,all patients' post-operation relief.6-months after operation,the quantity of vision reached or exceeded BCVA were 228 cases ( 96.61％ ),average refraction wsa ( + 0.54 ± 0.24 ) D,the incidence of haze was 4.66％.Conclusion Is safe the LASEK combined with MMC in treatment of high myopia,effective,low incidence of haze.

More than 40 institutions have set up the specialty of medical law in order to train inter-disciplinary talents of medical law.Many scholars undertook extensive research aiming at strengthening and developing this new specialty,but many problems still existed in its teaching and the quality of the graduates was been questioned.Through in-depth analysis of the existing research,we pointed out three problems of the current research:being subjective and lacking data support; confining to the ivory tower and lacking contact with the social; limiting to scholars and teachers and lacking retrospective thinking and critique from postgraduates.

Objective To discuss the clinical curative effect on maxillary sinusitis nasal endoscopic single path surgical treatment and provide reference for the clinical treatment.Methods A total of 52 patients of fungal ball type maxillary sinusitis were randomly divided into group A(26 patients) and group B (26 patients).The patients in group A were treated by endoscopic single path surgical treatment and the patients in group B were treated by intranasal antrostomy.The clinical curative effect was analyzed.Results In group A and group B,the total effective rate was 88.5％(23/26) and 65.4％(17/26),there was significant difference (P ＜0.05).The remission rate of nasal obstruction,nasal discharge with suppuration,nasal discharge with blood,headache were 100.0％ (26/26),92.3 ％ (24/26),84.6％ (22/26),73.1％ (19/26) in group A,and 100.0％(26/26),88.5％(23/26),76.9％(20/26),65.4％(17/26) in group B.The recurrence rate in group A and group B was 0,15.4％(4/26),there was significant difference (P＜ 0.05).Conclusions The clinical curative effect of endoscopic single path surgical treatment is better,and the recurrence rate is lower.It is worthy of clinical application.
