1.A comparison study on auditory verbal learning ability among four different brain areas after stroke
Chinese Journal of Geriatrics 2012;31(2):105-109
Objective To compare the ability of auditory verbal learning,memory and retention between each side of thalamus and basal ganglia after stroke.Methods 63 patients with single lesion in thalamus or basal ganglia after stroke,34 patients with amnestic mild cognitive impairment (aMCI)and 34 healthy control subjects received auditory verbal learning test.Results There was an overall decline of immediate and delayed recall,retention ability in patients with single lesion of stroke as compared with the healthy control group(P<0.05).Both the left thalamic stroke group [(19.0± 3.1)scores]and aMCI group[(17.6 ±3.3)scores]showed similar pattern in damaged recognition ability,while this ability still existed in the other three stroke groups.The ability of auditory verbal learning in the left thalamic stroke group[(2.2 ± 2.0)scores]and right thalamic stroke group[(2.1 ± 1.9)scores]were lower than in the healthy control group[(3.6 ± 1.8)scores](P <0.05).The retention ability in the left thalamus stroke group[(2.8±1.7)scores]and the right basal ganglia stroke group[(2.7 ± 1.9)scores]was decreased than in the healthy control group[(1.7±1.4)scores](P<0.05).Conclusions There is decline of AVLT-learning,memory and retention ability in patients with single lesion stroke,especially in the left thalamus stroke patients.Moreover,the pattern of impairment in the left thalamus stroke is similar to aMCI but different from the other three stroke groups.
2.SOMATOTOPICAL LOCALIZATION OF THE RAPHE—SPINAL PROJECTION IN THE RAT A RETROGRADE HRP STUDY
Acta Anatomica Sinica 1955;0(03):-
Retrograde HRP technique was used to study the somatotopical organization of the raphe—spinal projection of the rat. HRP or wheat germ agglutinin conjugated HRP was injected into unilateral gray matter or dorsal horn of the cervical cord or lumbar cord. The following conclusions have been reached.The caudal part of NRM projects to areas ventral to the dorsal horn. Projection to the dorsal horn was found to originate from the rostral part of NRM, which is somatotopically localized. Cells projecting to the cervical dorsal horn are distributed more rostrally than those to the lumbar dorsal horn, although an extensive overlapping of these two parts is evident. Somatotopical localization in the form of "gap" as suggested by Watkins et al. could not been verified in our experiment.The functional significance of the sornatotopical organization of NRM is discussed.

Chinese Journal of Emergency Medicine 2010;19(7):757-760
Objective To study the prevalence and distribution of dental trauma in children and adolescents. Method A total of 347 patients with the permanent anterior teeth injured aged from 6 to 25 years were treated and selected from July 2008 to June 2009. Data of gender, age, site of accident occurred, number of teeth injured, and location and type of injury were taken from the dental records. Results Of them, there were male 219, female 128, and the ratio of male/female was 1.7:1.0, The highest incidence of tooth injuries occurred a-mong children of 10 to 13 years old. The common site of dental trauma was school. The majority of dental casualties had one tooth (38.0%) and two teeth (38.0%) injured. Of all types of dental injury, subloxation (19.8%), and enamel and dentin fractures without pulpa involvement (18.7%) were the most seen ones. Con-clusions The dental trauma in children and adolescents is a major problem that can not be ignored, and should be given persistent attention to prevent.

5.Thoughts on Improving Data Integrity of Pharmaceutical Production Enterprises
China Pharmacy 2017;28(13):1732-1735
OBJECTIVE:To provide reference for improving the data integrity management system of pharmaceutical produc-tion enterprises. METHODS:According to related reports in US Food and Drug Administration(FDA)and China Food and Drug Administration(CFDA),the source of data integrity problems was analyzed,its reasons were summarized and solutions were put forward. RESULTS&CONCLUSIONS:The reasons why there were data integrity problems in enterprises can be attributed to 3 as-pects(staff,hardware/software system and quality management),and the 3 aspects showed large gap with current standards. It is suggested that enterprises evaluate the existing system by adopting the gap analysis,establish a data integrity management project team,strengthen personnel training,upgrade hardware/software system to ensure its safety,stability and effectiveness;and opti-mize the quality management system by developing good ducument specification,special regulation system of data integrity. In addi-tion,the enterprise should establish quality culture,pay attention to industry and regulatory trends in real time to guarantee the data integrity effectively.

Objective:To evaluate iron metabolism disorders in sepsis patients and explore the effect of iron deficiency on mortality.Methods:Patients ( n=130) who were admitted to the emergency intensive care unit (ICU) of the First Affiliated Hospital of Dalian Medical University from September 2016 to July 2018 and met the diagnostic criteria of Sepsis 3.0 were selected, and sex- and age-matched healthy volunteers ( n=20) were enrolled as a control group. Peripheral venous blood samples were collected in sepsis patients on day 1, 3 and 7 after admission, or in the healthy volunteers upon enrollment, to detect iron metabolism-related indicators and interleukin-6 (IL-6); the Sequential Organ Failure Assessment (SOFA) score was calculated upon hospital admission. Iron metabolism-related indicators were compared between the groups; the correlation of plasma iron with hemoglobin, hepcidin, ferritin, IL-6, sTFR/log ferritin and the ability of plasma iron to predict 28-day death of sepsis patients were analyzed. Results:Sepsis patients developed significant anemia on day 3 after admission; plasma iron, transferrin, iron saturation, total iron binding capacity and unsaturated iron binding capacity in the first week of admission were significantly lower than those in the control group; distribution width of red blood cells, ferritin, IL-6, hepcidin and soluble transferrin receptor were significantly higher than those in the control group. Distribution width of red blood cells, ferritin and hepcidin on day 3 and 7 after admission, and plasma iron and iron saturation on day 7 after admission were significantly higher than those on day 1. However, total iron binding capacity and unsaturated iron binding power on day 7, and sTFR/log ferritin on day 3 were significantly lower than those on day 1. Patients in the survival and non-survivor groups in the first week of admission had significant anemia on day 3 and 7, but the anemia was worse in the non-survivor group. Transferrin, total iron binding capacity, and unsaturated iron binding capacity in the non-survivor group in the first week of admission, and plasma iron in the non-survivor group on day 3 and 7, were significantly lower than those in the survival group. Ferritin, IL-6 and hepcidin in the non-survivor group in the first week of admission, and iron saturation on day 7 were significantly higher than those in the survival group. Spearman correlation analysis showed that plasma iron was negatively correlated with IL-6 ( r=-0.391, P<0.01), ferritin ( r=-0.293, P=0.001) and hepcidin ( r=-0.209, P=0.017), but not with hemoglobin ( r=0.005, P=0.958). The area under the operation curve (AUC) for plasma iron for predicting 28-day mortality in sepsis patients was 0.524 (95% CI: 0.416-0.631, P=0.656). Conclusions:Sepsis patients have significant anemia and iron metabolism disorders in the early stage, while non-survival patients are more severe. Reduced plasma iron level has no capacity to predict 28-day mortality of sepsis patients. In addition, decreased plasma iron level is not related to decreased hemoglobin, and thus iron supplementation should be cautious in sepsis patients.

BACKGROUND: The rehabilitation outcome varies in stroke patients,and there are differences in the literatures about the influence of factors on the functional recovery in such patients.,OBJECTIVE: To evaluate the pre-rehabilitative and post-rehabilitative effects of stroke patients by functional independence measure (FIM) that is widely used, and analyze the influence of gender, age, motor and cognitive functions at admission, time interval from stroke onset to arrival at rehabilitative admission, comorbidity occurrence, laterality of lesion on the functional recovery of stroke patients.DESIGN: Before-after control observationSETTING: Center of Rehabilitation Medicine, Shandong Provincial Hospital; Faculty of Rehabilitation Medicine, Capital University of Medical SciencesPARTICIPANTS: From March 2000 to December 2002, 55 stroke patients were selected from Shandong Provincial Hospital. They were all first episode, and patients whose bilateral cerebral hemisphere were involved were excluded.METHODS: After the vital signs were steady, the stroke patients got through risk phase (31-75 days) and were treated with medicine improving microcirculation and providing neurotrophic factor for nerves. In addition, they accepted comprehensive rehabilitation training of Bobath technique, PNF technique and Rood method mainly, with 1-2 hours per day and five times per week.MAIN OUTCOME MEASURES: The patients were evaluated within 7days after admission and reassessed 3 days before discharge using FIM,including 18 items of motor and cognitive functions and 126 total scores (108-126 as elementarily or completely independent, 72-107 as mildly dependent, 54-71 as moderately dependent, 36-53 as severely dependent,18-35 as extremely or completely dependent). Multiple stepwise regression equation was applied to analyze the relation of above factors and functional recovery (increased value of FIM total score).RESULTS: Totally 55 patients were involved into the result analysis.①FIM total score of patients was significantly higher at discharge than at admission (93.8±12.0, 68.8±11.6, P < 0.001), and motor function and cognitive function at discharge also increased compare with at admission (P < 0.001).②Mean value of FIM motor score increased everyday was identical with that of total score (0.56±0.21, 0.59±0.21), and higher than mean value of cognitive score (0.03±0.03).Multiple stepwise regression analysis showed,scores of motor and cognitive status at admission, age, time interval from stroke onset to arrival at rehabilitative admission all affected the increased value of FIM total scores. No significant association between gender, comorbidity, laterality lesion of paralysis and functional recovery was observed (P > 0.05). The most influential factors were orderly motor function,cognitive function at admission, age and time interval from stroke onset to arrival at rehabilitation admission.CONCLUSION: Motor and cognitive function at admission, age and time interval from stroke onset to arrival at rehabilitative admission have a no table relationship with functional recovery of stroke patients, especially motor function at admission is positively related. Thus we should not neglect the influence of these factors when conducting rehabilitative treatment.
