Objective:To study the effect of articulation disorder on psychology action of cleft palate patients after operation.Methods:65 patients were asked to answer the psychology questionnaire.Results:The patients of misarticulation all have some degree of psychological disability,and unusual psychology action would affect pronunciation treatment.Conclusion:Patients with misarticulation have psychology problems in some degree,which would affect the clinic treatment of cleft palate.

Polyactin B (Pb) has been proved to have the effect of considerable tumor suppression. Recently,we used murine S_(180) Sarcoma as a model and observed the effect of Pb on the tumor—infiltrating immunocompetent cells, and also the infiltrating neutrophils and the alteration of small blood vessels within the tumor tissue. Compared with control: in Pb—treated group, there were more L_3T_4~+and Lyt_2~+ lymphocytes infiltrating in the periphery of the tumor ,and also within the tumor. In addition, the tumors had more prominant hyperemia, micro—thrombosis and neutrophil infiltration around the necrotic areas. The present findings suggest that the tumor—suppression effect of Pb might be mediated through TNF produced by immunocompetent cells.
6. Apoptosis of lumbar spinal cord neurons in cauda equina syndrome rats
Academic Journal of Xi'an Jiaotong University 2010;22(2):120-122
Objective: To explore the law of apoptosis of lumbar spinal cord neurons in cauda equina syndrome (CES). Methods: Cauda equina of rats was compressed by a piece of silica gel stick. From day 1 to day 28, the lumbar spinal cord specimens were harvested and assessed by Nissl's staining and TUNEL staining. Results: Compression of cauda equina caused lesion and apoptosis of neurons in lumbar spinal cord, and the extent of apoptosis reached the peak on 7th day after compression. Conclusion: Apoptosis of neurons in lumbar spinal cord might be one of the reasons why patients with CES get poor prognosis.

8.A clinical study of the relationship between insulin level and mild cognitive impairment in type 2 diabetes subjects
Chinese Journal of Diabetes 2008;0(07):-
Objective To investigate the relationship between insulin level and mild cognitive impairment(MCI) of type 2 diabetes and analyze the risk factors for MCI. Methods We collected 101 type 2 diabetes subjects who were divided into two groups:MCI and normal cognition(NC).All subjects were evaluated with cognition scores of MMSE,GDS,CMS,ADL.Insulin,glycosylated hemoglobin,blood routine test,blood pressure,ECG,brain CT were detected.Independent t-test,correlation and multiple regression analysis were performed. Results 1. The diabetic patients with MCI showed the higher levels of insulin at fasting, 2hr and 3hr after meal than did NC(P

Objective To assess the clinical application value of magnetic susceptibility-weighted imaging in cerebral vascular malformations. Methods Thirty-six patients with cerebral vascular malformations were enrolled in the study. All the patients received examination of T1WI, T2WI and SWI. SWI sequence was compared with T1WI, T2WI sequence in detecting and diagnosing cerebral vascular malformations. Results Cerebral vascular malformations were low signal in SWI sequence. Cavernous angioma, developmental venous anomalies and AVM had been found in 73,8,10 cases, respectively. The bounder of lesions was clearer, more multiple small lesions, more hair-thin pulp veins and draining veins were detected in SWI sequence. Conclusion SWI sequence has more sensitivity than T1WI and T2WI sequence in detecting the cerebral-vascular malformations. SWI sequence may become routine examination se- quence in diagnosis cerebral-vascular malformations.

AIM: To observe the changes in contrast sensitivity (CS) between emmetropic pilots, glasses wearing, and after laser in situ keratomileuses ( LASIK) surgery pilots, provide the basis for the physical examination standard after operation.
METHODS:The CS of 13 emmetropic pilots (26 eyes), 12 glasses wearing pilots (24 eyes) and 10 with LASIK (20 eyes) , under photopic, scotopic and scotopic with glare environments at four different spatial frequencies ( 3, 6, 12 and 18cpd ) were measured and the resluts were analyzed by statistics.
RESULTS:Under photopic environments, there was no significant difference in the low spatial frequency (3cpd) among the three groups (P>0. 05). The CS of emmetropic pilots was better than that of the myopic and with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05). Under scotopic environments, there was no significant difference in the low spatial frequency (3cpd)among the three groups (P>0. 05). The CS of emmetropic and with LASIK pilots were better than that of the myopic, and there was significant difference ( P<0.05). There was no significant difference in CS between emmetropic and with LASIK (P>0. 05). Under scotopic with glare environments, the CS of emmetropic and myopic pilots were better than that of the with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05).
CONCLUSION: The CS after LASIK is decreased compare with emmetropic pilot, specially under scotopic with glare environments. A perfect identification standard should be set up.
