OBJECTIVE:To summarize general regularity and characteristics of amiodarone-induced pulmonary toxicity,and to provide reference for rational use of amiodarone and avoiding the occurrence of ADR. METHODS:Retrieved from CNKI,VIP and Wanfang database,individual case report literatures about amiodarone-induced pulmonary toxicity were collected during 1990-2016. The included cases were analyzed statistically. RESULTS:A total of 19 related literatures were collected,involving 20 cases of amiodarone-induced pulmonary toxicity. Among them,the patients older than 60 years old accounted for 75.0% with ratio of male to female 3:1. 75.0% patients had used medicine more than 1 month when pulmonary toxicity occurred. The dose of amiod-arone in 17 patients ranged 200-400 mg/d. Six patients died,accounting for 30.0%. CONCLUSIONS:Pulmonary toxicity induced by amiodarone may be related to patients'gender,age,dose and medication time. The mortality of it is in relative high level. Med-ical staff should pay attention to it,regularly monitor and process it timely.

Objective To develop a new quantitative analytical method for determination of fluoroacetamide,a kind of raticides,in blood and urine samples using solid-phase extraction combined with GC/MS.Methods Using acetamide as the internal standard,extraction column and extraction conditions of fluoroacetamide from blood and urine samples were optimized by comparing the extraction efficiency of different solid-phase extraction columns and the effects of experimental conditions on recovery.By means of the quantitative relation between the ratio of characteristic ion peak areas of fluoroacetamide to acetamide a novel analytical method for determination of fluoroacetamide concentration was established by quantitative GC/GM technique.Results The ratio was proportional to the concentration of fluoroacetamide ranging from 5.0 to 90?g/ml with silica gel column extraction,and the detection limit was estimated to be 1.0?g/ml.The average recovery of fluoroacetamide in blood sample was 91.6%.The standard deviation was less than 7.3%.Conclusion The analytical results were in conformity with those obtained by the classical method,which could satisfy the requirement for quantitative measurement of fluoroacetamide in samples from practical cases.

The changes of pulmonary platelet trapping (PPT) were observed in dogs after they were traumatized with steel-sphere shooting and then the therapeutic effects of nalorphine were studied.It was found that the PPT rate was significantly increased in the 8th hour after injury;when nalorphine was administered before and after gunshot wounding,the PPT rate of the traumatized dogs was signficantly lowered.The fact indicates that the increase of PPT rate in the gunshot dogs results from the activation of opiate ? receptor in the lungs.

Objective: To study the chemical constituents of the flowers of Impatiens balsamina L.. Methods: The compounds were isolated by chromatography and solvant extration and the structures were identified on the basis of spectral analysis. Results: Four compounds were isolated and identified as stigmasterol(1), kaempferol(2), Kaempferol 3 glucoside(3) and Kaempferol 3 glucosyl rhamnoside(4). Conclusions: All the compounds were isolated from the flowers which were cultured for the first time in China.

Objective To explore the MRI features of acute optic neuritis with positive aquaporin?4 (AQP4) antibodies and myelin oligodendrocyte glycoprotein (MOG) antibodies during the first attack. Methods Eighty five patients (105 affected nerves) with first?episode AQP4?seropositive optic neuritis (AQP4?ON; n=58; 64 affected nerves) and MOG?seropositive optic neuritis (MOG?ON; n=27; 41 affected nerves) diagnosed by our hospital Neuro?ophthalmology Department between April 2014 and December 2017 were retrospectively analyzed. Double seronegative patients or double seropositive patients were not included. All patients underwent orbital conventional MRI; 29 patients also underwent RESOLVE?DWI and 55 underwent brain T2 fluid?attenuated inversion recovery (T2FLAIR). Theclinical features (age, gender, disease duration) and MRI features (T2WI, bilateral involvement, the degree and extent of enhancement, the extent of involvement, the affected segment and ADC values of nerve; demyelinating lesions of brain) were analyzed by 2 doctors. The qualitative parameters were compared with χ2 test or Fisher exact test and the quantitative parameters were compared with two independent sample t test (normal distribution) or the Mann?Whitney U test (skewed distribution). The Kappa test was used to test the consistency of the qualitative characteristics of the images evaluated by the 2 doctors. The interclass correlation coefficient (ICC) was used to test the consistency of the ADC obtained by the 2 doctors. Results There were no significant differences in the distributions of age and disease duration between 2 groups (t=1.911, Z=-1.054, P>0.05). AQP4?ON had a higher female proportion (χ2=13.911, P<0.05) and showed mainly unilateral involvement. MOG?ON more commonly showed bilateral involvement (χ2=17.640, P<0.05), but there were no significant differences in the demyelinating lesions of brain (χ2=0.000)and the presence/absence of optic tract involvement (both P>0.05). There was a higher probability of optic nerve swelling, long segmental lesions and optic nerve head involvement in MOG?ON(χ2=16.845, 13.525, 13.264, P<0.05). Moreover, the rate of obvious enhancement and the involvement of optic chiasm was higher in AQP4?ON(χ2=7.152, 5.088, P<0.05). RESOLVE?DWI showed the ADC values of the AQP4?ON were significantly lower than those of MOG?ON (t=-3.300, P<0.05). The qualitative features of image evaluated by the 2 doctors were consistent well (Kappa=0.712-0.932, P<0.001).The ADC values obtained by the 2 doctors were consistent well (ICC=0.942, P<0.001).Conclusions For the first?episode acute optic neuritis, AQP4?ON hasobvious female predilection and the trend of unilateral involvement and obvious enhancement, while MOG?ON isoften involved bilaterally with longitudinally extensive lesions. The ADC values of the AQP4?ON are significantly lower than those of MOG?ON and AQP4?ON are more vulnerable to involve the optic chiasm. Conventional MRI and RESOLVE?DWI are helpful for differentiating AQP4?ON from MOG?ON during the early stage of the disease course.

Based on the theory of "Johari Window", this study introduced how to stimulate information content obtained in doctor-patient communication and how to apply the comprehensive geriatric assessment creatively from the four modules of open area, blind area, hidden area and unknown area in the model. It helped students to gain the trust and cooperation of patients, rapidly narrow down the blind area, hidden area and unknown area, guide patients to actively extend the open area, improve the teaching quality of doctor-patient communication in a scientific way.

Metaiodobenzylguanidine (MIBG) is an analog of norepinephrine that accumulates in sympathetic nerve endings soon after intravenous administration. The degree of accumulation reflects the uptake, storage and release of transmitters by noradrenergic neurons. Myocardial imaging with ¹²³I labeled MIBG ( ¹²³I-MIBG) can be used to estimate the extent of local myocardial sympathetic nerve damage, which has been widely used in the diagnosis and treatment of various heart diseases. In recent years, numerous studies have been carried out on the application of ¹²³I-MIBG in the diagnosis of degenerative diseases of the nervous system (such as Parkinson's disease and dementia of Lewy body), and have made some achievements. The purpose of this review is to summarize the current clinical application of ¹²³I-MIBG myocardial imaging in the diagnosis of dementia with Lewy bodies, the problems in imaging technology and the possible research directions in the future, so as to provide valuable reference information for clinicians to reasonably and accurately apply this technology in the early diagnosis and discrimination of dementia.
