Objective To develop stress vulnerability prediction scale for soldiers.Methods 148 items were determined by reviewing items in relating literatures and scales,interview,panel discussion and expert consultation.Then 431 and 351 soldiers in two times were picked out randomly as samples from Army Northwest District.Item analysis,exploratory factor analysis,reliability analysis and confirmatory factor analysis were used to analyse the data.Results Stress vulnerability prediction scale comprised five subscales:traumatic events,positive affect,negative trait,negative coping and interpersonal support.The scale was comprised of 59 items,and the factor loading of the items ranged from 0.503 to 0.839.Cronbach's α coefficient of the five subscales were 0.777,0.903,0.923,0.882,0.908,and the Cronbach's α coefficient of the scale was 0.895.Confirmatory factor analysis showed a higher goodness of fit(RESEA =0.058,NFI =0.89,NNFI =0.93,CFI =0.94,IFI =0.98).Conclusion Stress vulnerability prediction scale in soldiers has good psychometric properties,and can be used as a prediction measurement tool for measuring the stress disorder for soldiers.

Objective To evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) on unilateral spatial neglect in stroke patients. Methods Published articles from the earliest date available to July, 2016 were recalled from PubMed, OVID, Embase, Co-chrane Library, CNKI, VIP and Wanfang Database. Two reviewers selected independently the randomized controlled trials (RCTs) about rT-MS for stroke patients with unilateral spatial neglect, and extracted data independently and analyzed with RevMan 5.3 and GRADE profiler 3.6. Results Twelve trials that represented 353 participants were evaluated. For improving Line Bisection Test, Star Cancellation Test, Albert Test, rTMS groups were significantly more effective than the controls. rTMS groups with different frequencies all showed significantly effec-tive:for low frequency rTMS, SMD=-1.21, 95%CI=-2.17 to-0.25;for high frequency rTMS, SMD=-2.56, 95%CI=-3.54 to-1.58;for continuous theta burst stimulation (cTBS), SMD=-2.51, 95%CI=-3.66 to-1.36. Conclusion rTMS is effective on unilateral spatial neglec-tin in stroke patients.

Objective The aim of this study was to investigate the radiation dose caused by 18 F-fluorodeoxyglucose (FDG) in PET/CT examination and to optimize the concerned radiation protection. Methods Thirty patients from our conventional PET/CT examination were simple randomly selected, and they all underwent whole body PET/CT imaging. The radioactive dose of injected 18F-FDG was recorded. The internal radiation dose was calculated and the external radiation dose from patients was measured with the 451P-DE-SI ion chamber survey meter. The staff's dose was recorded with thermoluminescent detector (TLD). All dosimetry data were processed and analyzed statistically with Excel 2003. Results The injected radioactive dose of 18F-FDG was (432.9±51.8) MBq, and effective dose equivalent received per patient was (8.23±0.99) roSy. The correlation coefficient (r) of the dose equivalent rate and distance was-0.994 by power function curve fitting, and that of dose equivalent rate and time was - 0.988 by exponential curve fitting. The staff's dose was lower than the annual dose limit. Conclusions The patient's internal radiation dose caused by 18F-FDG in PET/CT examination is low, nonetheless, the clinician should always consider optimizing and minimizing the necessary radiation received by the patients. The patients having been injected with 18F-FDG should stay in one place to decrease their radiation to the public. From the medical point of view in optimizing radiation exposure, there may still be a potential to lower the injected 18F-FDG activity.

Objective To measure the normal cerebrospinal fluid of the midbrain aqueduct peak velocity of different age groups by using magnetic resonance imaging (MRI) time‐spatial labeling inversion pulse (time‐SLIP) ,and to discuss the flow law of CSF . Methods Forty‐one cases of healthy volunteers ,including 23 cases of male ,18 cases of female ,aged 7 -73 .Patients were divided into 4 groups:7- <15 age group (n=11) ,15- <35 age group (n=10) ,35- <45 age group (n=9) ,≥45 age group (n=11) .We used the application of Toshiba 1 .5 T MRI head coil ,MRI sequence of time‐SLIP marked CSF to calculated the peak velocity of CSF in the midbrain aqueduct and measure the diameter and length of the midbrain aqueduct .Results The peak flow velocity be‐tween the 7- <15 age group and 15 - <35 age group ,35 - <45 age group ,≥45 age group were statistically significant (P<0 .05);inner diameter and length were no statistically significant difference (P>0 .05) between age .Conclusion In the midbrain aqueduct ,CSF is two‐way flow and supports the CSF of the pulsatile flow theory ;MRI sequence of time‐SLIP could measure CSF velocity and display the turbulence fluiding .

Objective: To evaluate the pharmacological actions on blood quickening and stasistransforming of Gongqing Granules (Herba Leonuri, Herba Portulacae, Pollen Typhae, etc).Methods:Fibrinolysin dissolving, blood stagnation model induced by adrenaline hydrochloride, natural bleeding, capillary coagulation.Results: Gongqing Granules could obviously increase whole blood and plasma viscosities and packed cell volume, and obviously shorten the time of fibrionolysin dissolving. It showed no evident effect on the time of bleeding in mice and could shorten the time of capllary blood coagulation in rats.Conclusion: Gongqing Granules has strong actions of blood quickening and stasis transforming.

The application perspective of microwave-induced thermoacoustic tomography is also included.

Partial immunoactivities of peptidoglycan(PG)isolated from lactic acid bacteria were investigated.PG isolated from strain Z8 and Z17 of lactic acid bacteria respectively,had similar immunoactivities.The phagocytic function of M?(macrophage)increased markedly and serum lysozyme activity was significantly enhanced by injection of PG-extracts on mice.Investigation of immuno-enhancing effects of PG on vaccine of Newcastle disease in chickens showed that the hemagglutination inhibition levels of PG were higher than that of the control and the level was maintained for a longer time as compared to the control.
