Objective To explore mechanisms of sustained and transient effects in encoding processes of emotional memory by examining activation of amygdala via functional MRI and to provide evidence for understanding the underlying neural mechanism related to emotional memory disorders further. Methods Twenty two subjects (aged from 20 to 24 years old) participated in the study and mixed blocked/event-related design was adopted. Sixty negatively emotional pictures and sixty neutral scene pictures were used. Functional MRI scanning was performed while subjects were doing encoding tasks. Behavioral data were acquired during retrieval. Correlation analyses of functional MRI data and simples paired t -test of behavioral performance were performed with SPM2 and SPSS13.0 statistical software,respectively. Results Significant differences of behavioral performance ( t= 2.791,P= 0.01 ) was found between emotional (3.15 ± 0.14) and neutral (2.25 ± 0.08 ) pictures. A whole-brain voxelwise correlation analysis between functional MRI and emotional enhancement effect indicated that the transient effect of emotional enhancement of memory involved the left amygdala, left hippocampus and left lateral orbitofrontal cortex, while the sustained effect involved the right amygdala, right hippocampus, right inferior frontal gyrus, right medial and lateral orbitofrontal cortex. Region of interest analysis demonstrated that the sustained effect was related to the right amygdala (r= 0.50, P = 0.019 ), which was different from transient effect ( Z = 1.655, P = 0.049 ),while the transient effect was correlated with the left amygdala (r=0.65, P=0.001 ) ,which was different from sustained effect( Z= 2.512, P=0.006). Conclusion Different neural mechanisms are involved in sustained and transient effects of emotional memory encoding. The right amygdala is responsible for sustained effect and the left amygdala is responsible for transient effect ,respectively. The results confirm and extend the model of the left-transient/right-sustained effect.

Objective To determine the influencing factors of post-stroke depression by machine learning.Methods Stroke patients' medical records (688 cases eligible) were extracted from record system,including age,gender,pulse manifestation,complexion,tongue quality,fur,Chinese medicine intervention,body mass index (BMI),blood pressure,blood glucose,blood triglyceride,blood total cholesterol,smoking history,drinking history,depression family history,stroke lesion site in imaging,as well as the final depression judgment.Single rule algorithm (1R) was adopted to learn.The risk factors influencing post-stroke patients' depression in extracted information were determined.Then the cases collected were divided into the training dataset (500 cases) and the test dataset (188cases).Optimal discriminant results were obtained by random forest model.Results Single rule algorithm showed that the most important influencing factor of post-stroke depression was stroke lesion site.By computer speculation,stroke lesions in the frontal and temporal lobes were most prone to post-stroke depression.Basal ganglia,brain stem,cerebellum,medulla oblongata and occipital lobe lesions were less likely to cause depression.The accurate classification rate could amount to 88.95％ (612/688 cases).Random forest model determination was made in the former 500cases in the training dataset.The total correct rate of determining depression was 98.2％.The total correct rate of determination in 188 cases of the test dataset was 99.47％.Six hundred and eighty-eight patients' data were learnt by random forest model.The total correct rate was 98.84％.The importance measure results showed that top 3 important indexes of post-stroke depression were lesion site,Chinese medicine intervention and depression family history.Conclusion Patients with lesions in the frontal & temporal lobes and depression family history were most prone to post-stroke depression.

Objective To evaluate ligation of the intersphincteric fistula tract plus core-out fistulectomy for complex cryptoglandular anal fistulas.Methods Forty-one patients were divided into ligation and control group randomly.In ligation group (20 cases),patients underwent ligation of the intersphincteric fistula tract plus core-out fistulectomy procedure.While in control group (21 cases) fistulotomy on low sphincter with cutting-seton on high sphincter procedure was performed.The primary end points of the study were healing rate and continence by using the Wexner score.Secondary end points were postoperative pain in the third and seventh day with the use of the visual analog scale,length of hospital stay and followed measures for a recurrent fistula.Comparison of measurement data using independent samples t-test or paired samples t-test,compared with the count data using Fisher's exact test.Results There was no statistical difference in the healing rate between ligation group (90％) and control group (95％) (P ＞0.05).Postoperatively,one case in ligation group reported incontinence for gas,compared to 7 cases in control group,among these 7 cases 2 cases also had incontinence for watery stool.Statistical differences were found between two groups in Wexner scores,visual analog scale scores and length of hospital stay (P ＜0.05).Conclusion Ligation of the intersphincteric fistula tract plus core-out fistulectomy is an economical,safe,little painful,recovery enhanced and minimally invasive technique to treat complex anal fistulas.

Objective To set up a method to determine cytoplasmic free calcium [Ca~(2+)]_(i) in human platelets with flow cytometry.Methods As a calcium indicator,Fluo 3-AM was used to determine the changes,induced by thrombin,of the level of platelet plasma free calcium [Ca~(2+)]_(i) in presence or absence of outside calcium [Ca~(2+)]_(o),in order to elucidate where the platelet plasma free calcium [Ca~(2+)]_(i) mainly come from and it's role in the activity of platelets.Results The geometric mean of fluorescence intensity of the platelet,labeled with Fluo 3-AM,was increased obviously.The concentration of platelet plasma free calcium [Ca~(2+)]_(i) was increased significantly by thrombin in a dose-and [Ca~(2+)]_(o)-dependent manner.Conclusion The increased level of platelet plasma free calcium [Ca~(2+)]_(o),induced by thrombin,mainly comes from [Ca~(2+)]_(o) and partly from the released [Ca~(2+)]_o of intra-platelet probably.

ObjectiveTo investigate the changes in serum levels of M30, M65, and interleukin-17 (IL-17) and their clinical significance in patients with acute pancreatitis. MethodsA total of 126 patients with acute pancreatitis who were admitted to our hospital from December 2009 to December 2013 were selected, and according to clinical diagnosis, they were divided into mild acute pancreatitis group (82 patients) and severe acute pancreatitis group (44 patients). A total of 107 healthy subjects who underwent physical examination during the same period of time were enrolled as the control group. On days 1, 2, and 4, the serum levels of M30, M65, and IL-17 were measured, and M30/M65 ratio was calculated. Comparison of coutinous data between multiple groups was made by ANOVA and pairwise comparison between any two groups was made by SNK-q test, comparison between two groups was made by independent-sample t test, while comparison of categorical data by chisquare test. ResultsOn days 1, 2, and 4, the severe acute pancreatitis group and mild acute pancreatitis group had significantly higher serum levels of M30, M65, and IL-17 (P＜0.05), and a significantly lower M30/M65 ratio (P＜0001), as compared with the healthy controls. On days 1, 2, and 4, the severe acute pancreatitis group had significantly higher serum levels of M30 and M65 than the mild acute pancreatitis group (P＜0.001); on day 1, the severe acute pancreatitis group had a significantly lower M30/M65 ratio than the mild acute pancreatitis group (P＜0.001); the serum level of IL-17 showed no significant difference between the two groups (P＞0.05). M65 and IL-17 had high sensitivity and specificity in the diagnosis of acute pancreatitis. ConclusionThe serum levels of M65 and IL-17 and M30/M65 ratio at 24 hours after the attack of acute pancreatitis can be used as the serological biomarkers for early evaluation of the severity of acute pancreatitis.

Objective:To explore the effect of quality control circle ( QQC) on the error control in PIVAS. Methods:QQC group was established in the department of PIVAS to reduce the errors in intravenous admixture practice. The status was analyzed using the total errors per week as the index, and the improvement target value was calculated by the eighty-twenty rule. The concrete causes for the errors were found out by the method of“brain storm”, and the main causes were confirmed using a fishbone diagram and the eighty-twenty rule, and then some countermeasures were summarized and carried out. The application effect of QQC was judged by the intan-gible and tangible outcomes before and after the activity, and some suggestions for the further improvement were provided. Results:Af-ter the implementation of QQC activity, the number of errors was reduced from 47 per week to 22 per week with the rate of target a-chievement of 104. 1% and the progress rate of 53. 2%. Moreover, QQC showed positive influence on the sense of being masters, co-operation ability, team spirit and sense of responsibility and confidence in the whole staff, and the ability of analyzing, summarizing and solving problems was also enhanced. Conclusion: QQC can significantly reduce the errors in the practice of intravenous admix-ture. The management method is valuable to explore and analyze the deep problems encountered in PIVAS in order to make rational and efficient measures. It is also helpful to improving the service conception of pharmacists and nurses, and enhancing the roles of pharma-cists in quality management and control to ensure medication safety.
