Objective: To examine the reliability and validity of self-report scale of brief psychopathological symptoms(SBPS). Methods: The reliability and validity of the scale were tested based on three groups of subjects, including the cases involved forensic problems, the patients with mental disorders and normal persons. Some of them were retested 5-15 days after first examination. Other subjects of them finished MMPI at the same time. Results: ①The Cronbach's ? coefficients of SBPS was 0.91. The split-half reliability was 0.90. The test-retest reliability ranged from 0.73～0.98. ②The correlations between factors scores and the total scores ranged from 0.79 to 0.87. The correlations among the four factors scores, ranged from 0.50 to 0.65. Significant correlation was found between the total scores of SBPS and the fake scores of MMPI (r =0.76). Based on the experts diagnosis, the accuracy rate of SBPS for evaluating malingering was 86.6%. Conclusion: The SBPS has acceptable psychometrics properties on reliability and validity.

Objective To explore the effect of oxytocin on uterine fibroids treated by ultrasound ablation. Methods Eighty-two single points in 29 uterine fibroids from 26 patients were sonicated with magnetic resonance imaging guided by high intensity focused ultrasound before and after using oxytocin. The required total energy, sonication time required to reach 60 ℃ and the acoustic energy for increasing 1 ℃ of temperature at the single point before and after using oxytocin were compared. Results Before intravenous infusion of oxytocin, the average total sonication energy required to reach 60 ℃ was (5320 ±910) J and it took (21 ±20) seconds for sonicating a single point, the energy required for increasing 1 ℃ was (255 ± 302) J. In contrast, after intravenous infusion of oxytocin, the average total sonication energy required to reach 60 ℃ was (2890 ±325) J, and it took (12 ±7) seconds for sonicating a single point, the energy required for increasing 1 ℃ was ( 126 ± 94 ) J. Those three index all reached statistical difference ( P = 0.002, P = 0.001, P= 0.002, respectively). Conclusion It seemed that Oxytocin could significantly decrease the energy required for ablating uterine fibroids, shorten treatment time and improve the treatment efficiency.

Objective To investigate the relationship between platelet maximum aggregation rate(MAR),platelet thrombocyt-ocrit(PCT),platelet count(PLT),platelet distribution width(PDW)and mean platelet volume(MPV)with the course of acute cere-bral infarction(ACI)to provide the basis for its clinical early diagnosis and treatment.Methods 107 patients with ACI in our hospi-tal were selected and divided into the great infarction group(infarction size >10 cm3 ),middle infarction group(infarction size 4-10 cm3 )and small infarction group(infarction size<4 cm3 )according to the infarction lesion size by head CT or MRI and the infarction volume calculated by the Pullicino formula(length×width×layer number/2),40 healthy individuals were selected as the healthy control group.MAR,PLT,PDW,MPV and PCT were detected before and after the induction by PLR-06.Results (1 )Compared with the control group,PLT,PCT,PDW and MPV before the induction by PLR-06 in the great infarction group were obviously in-creased(P <0.01);PLT,PCT,PDW and MPV in the middle and small infarction groups were increased(P <0.05).(2)Compared with the control group,MAR after the induction by PLR-06 in each infarction group was increased(P <0.05);PLT had no statisti-cal difference among the groups(P >0.05 );PCT,PDW and MPV in the great and middle infarction groups were increased(P <0.05);PCT,PDW and MPV in the small infarction group had no statistical differences(P >0.05).Conclusion The change of the platelet aggregation rate,number and volume is closely related with the occurrence and development of ACI,monitoring their change has important clinical significance to prevention and treat ACI.

Objective To evaluate the cost-effectiveness of various immuno-diagnostic systems for trichinosis and to find out the best testing system with low cost and high effectiveness.Methods The basic methods for the research are to difine and classify the direct and indirect cost for each testing system, and to identify a cost-effective testing system which would be practical and workable in case finding and/or mass survey. The data collected were analysed with parameters which are as follows: (1) the parameter of cost effectiveness expressed by cost/one sample in a given test that is unit cost. (2) the parameters of cost effectiveness: (a) for finding patients: cost/positive rate; (b) for examination carried out in normal individuals: cost/(100%-positive rate); (c) for the result of cross reaction: cost/(100%-cross reaction rate).Results Among the costs for detecting antibodies,the total costs vary from 98.06 yuan to 193.15 yuan. F-ELISA is the cheapest test. The unit cost for the five studied testing systems is ranging from 3.98 yuan to 4.22 yuan. According to the cost, the recommended order would be: F-ELISA, SPA-ELISA, ELISA, Western blot and IIP.Using the value of cost/effectiveness in analysis of the cost and comparing the results of detecting the positive cases ,the normal persons and cross reaction. The final results show that the methods for detecting antibodies are not only cheap but also practical and the preference for selection would be F-ELISA, ELISA and SPA-ELISA. The best method for detecting antigens is F-PcAb.Conclusions When these methods are used in practice, we suggest that F-ELISA should be the best method for choice in screening, when the result is positive, F-PcAb may be used for confirmation and can obtain a correct diagnosis.

The present study was aimed to investigate the pathological changes after magnetic resonance imaging (MRI) guided high intensity focused ultrasound (MRgHIFU) therapy for ablating the liver tissue adjacent to goat portal vein. Fifty goats were involved in this study. Normal liver tissues at 0, 5, and 10 mm distance from portal vein, respectively, were ablated with MRgHIFU. Among the 50 tested subjects, 40 goats were sacrificed immediately after the operations, and the other 10 were sacrificed 7 days after the procedure for pathological examination of the targeted areas and the contiguous portal veins. Coagulation necrosis was observed in all the treated liver tissues. Collagen swelling (CS) and vessel wall fracture (VWF) emerged more frequently in the 0 mm group than that in the 5mm group: CS [0 mm group VS 5mm group = 27/40 (67.5%) VS 7/40 (17.5%), P < 0.05], VWF [0 mm group VS 5mm group = 8/40 (20%) VS 0/40 (0%), P < 0.05]. Seven days after ablation, no portal vein damages (CS and VWF) were observed under light microscope. The results indicated that MRgHIFU could be used to ablate the liver tissue adjacent to goat portal vein effectively, which may cause blood vessel damage when the focus is on the wall of blood vessels (0 mm). However, the pathological results indicated that these damages are reversible.
