2.Common causes of headache and the treatment
Chinese Journal of Practical Internal Medicine 2001;0(06):-
Headache is a common clinical symptom.Some headache disorders belong to secondary category.Many intracranial disorders,such as head trauma,cerebral vascular diseases,intracranial tumors and inflammation,can lead to headache due to mass effect,inflammation reaction,stimulation of vasoactive substances and decreased intracranial pressure.Furthermore,many drugs and other substances,disorders of eyes,nose,ear,mouth,neck and other systemic disorders can also cause headache.Many headache disorders can be determined by detailed case history and physical examination.Blood test,lumber puncture,CT,MRI and other imaging examinations are necessary methods for finding the causes and the treatment of diseases.

Objective To analyze the sandtray topics of the children with behavior problems according to the grounded theory method.Methods Collected and described children' s sandtray topics of different types of behavior problems,age and gender.And analyzed them base on a 3 levels coding list compiling according to the ground theory method.Results The frequency of “negative theme” (3.33 ± 1.25 ) was higher than “positive theme” (0.81 ± 1.25 ) with significant difference (P<0.01) in feature level 1.Age factor had significant effect upon the frequency of “positive theme” in feature level 1 (P < 0.05 ).And also had impact on “harmony”,“ development” in features level 2 (F =3.039,P < 0.05 ).Gender factor,interaction of gender and age had significant effects on frequency of “negative theme” in feature level 1 (F =5.395,P < 0.05 ; F =4.222,P < 0.05 ).Conclusion The characteristics of the children' s sandtay with behavioral problems mainly are “negative theme”.And it shows different features in children with different gender or age.

Objective:To investigate the problems and improve the quality of clinical education.Method:A questionnaire was made among 200 medical students at Ji'ning medical college.Results:About eighty-eight percent of the students were satisfied with their clinical education,but there were still some problems:absence of clear objectives in clinical practice;shortage of enthusiasm of the students;lack of responsibility of some teachers and too many factors affecting clinical practice.Conclusion:The key points to improve clinical education quality are to set up clear education objectives,develop appropriate clinical practice methods,improve teaching staff quality and reform the teaching content.

ObjectiveTo observe the neuroprotective effect of basic fibroblast growth factor(bFGF)on cerebral diffuse axonal injuries (DAI)of rats.Methods40 male SD rats were randomly divided into control group, DAI injury group, bFGF group and DAI saline group. According to the survival time of rats, DAI injury group were divided into five groups, the 6h, 12h, 24h, 72h and 7th day group, The changes of bFGF expression in cerebral cortex were detected by immunohistochemical method from 6h to 7d after DAI. Two hours before DAI, bFGF 10μl was injected into right ventricle in bFGF group. ResultsThe bFGF expression appeared at 6h after DAI, increased at 12h, reached the highest level at 72h, and kept in a high level at 7d.There were obvious differences between 72h group and other groups in DAI injury group (P<0.01),cerebral cortex neurons were obviously decreased by HE staining. In each time group,injured neurons were decreased in bFGF group combined with DAI injury group(P<0.05). ConclusionsbFGF has obvious neuroprotective effect on cerebral diffuse axonal injuries of rats.

A simple and rapid gas chromatography/mass spectrometry (GC/MS) analysis method was developed for the determination of fat-soluble parts of sinapis semina. Four major compounds were chosen as marker compounds to evaluate the method. Various extraction techniques were evaluated and the greatest efficiency was observed with sonication extraction using diethyl ether. The method was valuated as follows:acceptable apparatus suitability was obtained by testing the resolutions, tailing factors and theoretical plate number of the marker compounds; the precision and reproducibility, expressed as relative standard deviation (RSD), fell within the prescribed limits. Eight samples of sinapis semina collected from markets in Xi’an were monitored by using the method. The fingerprints of those samples were analyzed by hierarchical cluster analysis (HCA) similarity analysis. The result indicated that the combination of fingerprint and HCA could be used to analyze sinapis semina from different habitats.

At present,the doctor-patient relationship in China is a little tense,communication between doctors and patients is not smooth,and the doctor-patient communication skills of the young doctor is obviously insufficient and need to be improved.In this paper,we analyze the factors that affect the communication between doctors and patients in the Department of Neurology through the complexity of professional knowledge,the current background and so on.In addition,we discuss multiple methods of improving communication capability among this group doctors,hoping to strengthen young physicians' clinical basic skills training,and impart doctor-patient communication skills from the linguistic modifiers,oral expression,words and deeds,use of metaphor,simulation training and other aspects,and establish dynamic assessment system of doctor-patient communication ability.

Objective: To investigate the influence of lidocaine on systemic inflammation in the perioperative ventricular septal defect (VSD). Methods: Twenty patients, scheduled for ventricular septal defect were randomly divided into 2 groups: lidocaine and control groups. Before rebeat lidocaine 1 mg/kg was given.The venous blood samples were obtained from the central venous at the following points: after induction of anesthesia and before cardiopulmonary bypass(CPB,T1),1 h after CPB(T2),2 h after CPB(T3), and 4 h after CPB(T4). IL-6 and IL-8 were determined by radio-immunoassay. Results: Compared with those at T1, the levels of white blood cells,polymorphonuclear neutrophils,IL-6 and IL-8 increased significantly from T2 to T4 in both groups. IL-6 and IL-8 levels reached the peak at T2. Compared with those in control groups, IL-6 level decreased obviously in lidocaine group from T2 to T4, but IL-8 level remained unchanged significantly. Conclusion: Under CPB and VSD repair the systemic inflammation is obvious, reaches the peak 30 min after CPB and persists to 4 h after CPB. Perioperative administration of lidocaine is effective against the inflammation.

Diabetic vascular complications are the key cause of the poor life quality and high mortality in diabetic patient. Advanced glycation end products (AGEs) and its cross-links play important roles in the diabetic vascular complications. Endothelial cells damage induced by AGEs may account for the initial agent for diabetic vascular complications. Recent studies have shown that AGEs inhibitors and breakers can prevent and reverse these complications. This article reviewed the research progress of AGEs and endothelium dysfunction. The potential therapeutic method was also stated.

Objective To simulate the dynamic procedure of bullet damage to the three-dimensional(3D) finite element(FE) model of mandible from different angle with computer-aided engineering.Methods A mandible was scanned by thin-layer CT,and then CT images were analyzed and managed with Dicom standard and Mimics software.At the same time,a simulation of the 3D FE model penetrated by a 7.62-mm bullet was carried out through LS-DYNA software from different angle.Results A 3D FE model of human mandible was established with highly-identical geometric size,and the dynamic process of bullet damage to the model was successfully simulated.The results of this work indicated that the exit wounds in model tended to be larger than the entrances resulting from the same shot.Conclusion Thin-layer CT and Dicom standard can improve the efficiency of establishment of a more precise 3D FE model of mandible.The procedure of bullet damage to the mandible can be simulated by the finite element.
