Aimed to cure dental anxiety,we summarized its clinical features,and also analyzed the etiological factors from therapeutic tools,medical treatment and patients.We adopted kinds of mental interventions,such as promoting patients' vulnerable mental state,eliminating their anxiety,providing therapeutic information,raising their confidence in recovery.By the above countermeasures,we have got satisfactory therapeutic effects in clinical practice.

Objective To evaluate quantitatively perfusion in coronary microcirculation by transvenous myocardial contrast.echocardiography(MCE).Methods Transvenous MCE was performed before and after LAD stenosis in 12 dogs.Results Peak intensity and area under curve(AUC)in time-intensity curves were significantly decreased after LAD stenois,peak intensity and AUC were strongly related with CBF flow(peakintensity:r=0.9405～0.09666,P=0.0005～0.0001;AUC:r=0.8239～0.9761,P=0.0103～ 0.0056).Conclusion Transvenous MCE could quantitatively assess the perfusion in coronary microcirculation.

Objective To provide a description of clinical manifestations, special imaging features and treatment of diffuse axonal injury(DAI).Methods Retrospective analysis of 32 cases of diffuse axonal injury.Result 87.5% patients were involved in traffic accident. All patients came into persistent comatose state immediately. 75% patients had abnormal CT scan findings. MRI showed more sensitive. It could reveal injury appearance of corpus callosum and brain stem clearly. Hypothermic therapy and calcium ion antagonist were used. Conclusions combination of clinical manifestations and special imaging features helped to diagnosis of DAI in early stage. Intensive care and preventing secondary brain injury were the important treatment points.

Objective To evaluate the clinical value of TVCDU in the diagnosis and followed-up of the gestational choriocarcinoma . Methods TVCDU and related clinical data of 21 patients suffered from the gestational choriocarcinoma during May 2003 and July 2004 were restrospectively analysed.Results The sonographic manifestations of choriocarcinoma could be classified into 5 types;(1)The uterine became larger than the normal , the local myometrium was changed into irregular non-echo region which was full of blood testified by CDFI(Color Doppler flow image);(2)The myometrium became nonhomogenity with plenty of blood flow , the resistance index ( RI ) was 0.25~0.47;(3)The abnormal echo emerged in the uterine cavity was not apparent boundary to the myometrium; (4)Neoplasm in the adnexa had relatively obvious blood flow,RI was about 0.4;(5)There was no abnormal echo in pelvic organ. The relation ship between sonographies and HCG first determined was complex. However,the lesions reduced, RI descended during the treatment of chemical therapy, so did the HCG .Conclusion TVCDU plays an important role in the differential diagnosis and the evaluation of curative effects of choriocarcinoma during the course of followed- up.

OBJECTIVE:To study the preparation of 5% albumin microspheres by sonication and the possible mechanism of microsphere forming.METHODS:The preparation technic was optimized with orthogonal design.The microsphere diameter was measured with Coulter multisizer and the outward apperance was observed with light and electronic microscope.RESUL_TS:The optimal preparation technic was as follows:5% albumin in NS,ultrasound power at 9th grade and 60 seconds of sonication.CONCLUSION:The albumin microspheres filled with air can be successfully prepared with orthogonal design and can be effectively used in intravenous myocardial contrast echocardiography.

AIM: To investigate the influences of native and oxidized lipoprotein(a) on human arterial smooth muscle cell (SMC) proliferation, change of intracellular free calcium concentration ([Ca 2+ ] i) and the protective effect of sodium ferulate(SF). METHODS: Lp(a) was oxidized by Cu 2+ and the extent of oxidation was assessed by the MDA content.Human SMC were incubated in culture media with SF for 12 h, then exposed to Lp(a) and oxidized-Lp(a), respectively. MTT colorimetry and flow cytometry were used to evaluated the proliferation of SMC and flurorescent indicator Fura-2/AM was used to determined [Ca 2+ ] i. RESULTS: ox-Lp(a) significantly promoted proliferation of SMC and increased[Ca 2+ ] i compared with Lp(a). SF(40,80 mg/L) remarkedly inhibited SMC proliferation and decreased the rising of [Ca 2+ ] i induced by ox-Lp(a) in a dose-dependent manner, but no effect on SMC proliferation and the increase in [Ca 2+ ] i induced by Lp(a).CONCLUSION: ox-Lp(a) induces the strong growth-promoting effect in SMC through increasing in [Ca 2+ ] i, which might be one of the cellular mechanisms responsible for the higher atherogenic potential of ox-Lp(a) compared with Lp(a), and this process can be prevented by inhibiting of oxidation by SF.

OBJECTIVE:To determine the content of C 3 F 8 in human albumin microspheres filling-with C 3 F 8 .METHODS:By Tekmar3000purge and trap concentrator coupled with a Hewlett-Packard5972GC/MSD.RESULTS:C 3 F 8 contents in samples were119.1～433.5?g/ml.CONCLUSION:The method is feasible and suitable for quality control.
