In this study a grey model GM(1,1) was developed on the basis of malaria cases reported for the period of 1986-1990 in China. In order to further enhance the predicting power of the model,residual correction is performed and the residual correcting GM(1,1)model was established. The result showed that the predicting performance of the latter model was much improved. The number of predicted cases for 1991(101 770) was conformed to the number of actual malaria cases reported (101 636).

Objective:To investigate the relationship between apolipoprotein E (ApoE) genetype and the depressed symptoms in patients with coronary heart disease. Methods:The genotypes and alleles of apolipoprotein E gene in 26 depressed patients with coronary heart disease,30 non-depressed patients with coronary heart disease and 30 healthy control subjects were examined with the polymerase chain reaction (PCR) and restriction fragment length polymorphisms (RFLPs) technique.Meanwhile, the HRSD was completed by all 86 subjects. Results:The frequency of Apolipoprotein E epsilon 4 in depressed patients with coronary heart disease was more than that in normal subjects .Especially the total cholesterol, HRSD and HAD in patients with the apolipoprotein E epsilon 4 were significantly higher than those in patients without the apolipoprotein E epsilon 4. Conclusion:Our results support the polymorphisms of apolipoprotein E gene were associated with the depressed symptoms in coronary heart disease. Apolipoprotein E epsilon 4 may play a major role in the pathogenesis of depressed symptoms in patients with coronary heart disease.

Objective: To evaluate the method,efficacy and complication of fluoroscopic guided local injection of Pingyangmycin lipiodol emulsion(PLE) in the treatment of body surface venous malformations(VM).Methods:Forty cases of VM,including 22 cases in the maxillofacial region,5 cases in the trunk and 13 cases in the extremities,received PLE local injection under X-ray fluoroscopy.PLE was prepared by mixing 2-8 mg of pingyangmycin(PYM)with 2-8ml of ultra-fluid lipiodol,the dosage was determined by the size of lesions.The effects and complications of PLE treatment were observed. Results:Signs of VM were patches of abnormal venous opacification and washout delay of contrast medium.Thirty four cases received single injection of PLE and 6 cases were injected twice.Excellent and good results were obtained in 20 cases and 16 cases respectively after 6 months post-injection,the therapy was ineffective in the rest four cases.Total efficacy was 90 percent.There were no severe complications such as skin necrosis or ectopic embolization. Conclusion: PLE intra-vascular injection under fluoroscopic guidance was convenient and safe for body surface VM.The merits of PLE treatment include accurate(localization,) safety,and excellent curative effect.

AIM:To compare the attention ability characteristics between the elite young female soccer players and ordinary female middle-school students,and analyze attention characteristics of the elite young female soccer players at different positions,so as to establish the distinction model for them.METHODS:The experiment was carried out in Soccer School of Shandong Province in October 2005 and Jining Institute Attached Middle School in March 2006.Sixty-four second-level or above outstanding young female soccer athletes were selected including 18 forward,20 halfback and 26 back persons.Meanwhile,80 ordinary female middle-school students served as controls.Using the Athletics Psychology Ability and Condition Diagnosis Test Software and WT-attention test software(1.0 version) developed by the Sports Research Institute of National Sports Bureau,the detection on the attention stability,attention assignment,attention shift,attention span and attention was carried out.The data were analyzed by normal distribution,T-test,and distinction analysis to establish the distinction equation for the attention characteristics of outstanding young female soccer athletes.RESULTS:144 subjects were all involved in the result analysis.①The attention ability of outstanding young female soccer athletes was significantly superior to that of the ordinary female middle-school student(P

Objective:To investigate the effect of cable pin internalfixation for treatment of patellar fracture.Methods:12 cases with patellar fracture were treated by cable pin internalfixation.Results:The post-operative function in 12 cases was evaluated according to Lu Yu-pu score,follow-up averaged 10 months,and the results were :excellent in 9 cases(75%);good in 2 cases(16.7%);fair in 1 cases(8.3%);poor in 0 case.The excellent rate was 91.7%.Conclusion:Patellar fracture treated with cable pin has the advantages of simple manipulation,firm fixation,faster and guaranteed fracture heeling and good function of knee.The method meets the demands of biomechanics and the clinical result of this group is quite satisfactory.It is advisable to use it in clinical practice.

Objective:To study the value of clinical application of 16-slice spiral CT in the diagnosis of acute chest pain.Methods:53 cases who presented with acute chest pain were included in the study.All of the patients underwent CTA examination to evaluate the coronary arteries,pulmonary arteries,thoracic and abdomen aorta.Coronary arteries angiography and interventional therapy was performed in 6 of the 53 cases.Multi-planar reconstruction(MPR),maximum intensity projection(MIP),curved-planar reconstruction(CPR)and volume rendering(VR)were used to display coronary arteries,pulmonary arteries,thoracic and abdomen aorta.The image quality was then evaluated according to whether the examinations can fulfill the clinical demand for the differential diagnosis of acute chest pain.Results:In the 53 cases,there were 33 cases with coronary arteries disease,9 cases with aortic dissection or dissecting aneurysm,2 cases with pulmonary arteries embolism,2 cases with spontaneous rupture of esophagus,2 cases with pneumothorax.Conclusion:CTA examination with 16-slice spiral CT can display the coronary arteries,pulmonary arteries,thoracic aorta in 11～13s with good image quality.It is of great value of clinical application in the etiological diagnosis for the patients with acute chest pain.

Objective:To investigate the constituents of indole alkaloids in Ervatamia yunnanensis and their antiaddictive bioactivities. Methods: The preliminary alkaloids(TEYA) were extracted by 95% EtOH from the stems of Ervatamia yunnanensis.TEYA was then purified by silica gel and Sephadex LH20 column chromatography repeatedly and its structure was identified with spectral analysis.The antiaddictive effects of these indole alkaloids were evaluated by Conditioned Place Preference(CPP) experiments.Results: Nine indole alkaloids were obtained and identified as: coronaridine(1),voacangine(2),3-R-ethoxycoronaridine(3),3-S-ethoxycoronaridine(4), 19-epi-heyneanine(5),heyneanine(6),19-epi-voacristine(7),coronaridine hydroxyindolenine(8) and 12-methoxyl-voaphylline(9).Among them voacangine (2) and 19-epi-voacristine(7) were effective in prevention and treatment of addiction induced by morphine in rats(n=8).Conclusion: Compounds 3,4,8,and 9 have been isolated from Ervatamia yunnanensis for the first time and coronaridine-type indole alkaloids are the main antiaddictive constituents of E.yunnanensis.
