Objective To investigate the emotional memory characteristic in patients with leuloaraiosis(LA) and explore the neurobiological mechanisms through observing the changes of emotional memory.Methods Different valence images (including positive,neutral and negative pictures) were used to test twenty-four patients with Leuloaraiosis(LA group)and twenty-four healthy colltrols(HC group) at the same time.The emotional memory was evaluated by the recognition of emotional pictures.Results In appraisal of the emotional pictures,there was no significant difference between patients with LA (positive (10.42±2.30) and neulral (12.87±2.29),respectively) and healthy controls (positive (11.38 ± 3.25) and neutral (12.75 ± 2.86),respectively) in positive and negative appraisal (all P＞0.05).But the negative appraisal decreased between LA group (11.63 ± 1.81) and HC group (12.75 ± 2.02) (P＞ 0.05).Compared with healthy controls (38.08+±5.45),patients with LA(33.67±7.10) showed sharply decline in the emotional images memorizing task(P＜0.05).And the accuracy in recognizing positive and netural valence pictures in patients with LA ((Positive(11.04±2.40) and neulral (10.42±2.93)) was significantly lower than that in healthy controls ((positive(12.79±2.17) and neutral(12.08±2.59))(P＜0.05).But in negative stimulus,there was no significant difference between LA group(13.20± 1.86)and HC group(12.20±2.65) (P＞0.05).In addition the total correct recognition,positive and neutral valence in pictures recognition were negativly correlated with the se verity of white matter lesions in the LA patients group(r=-0.308,P=0.033;r=-0.462,P=0.003;r=-0.352,P=0.014).Conclusion The emotional memory is impaired in patients with LA,and the degree of damage is accompornied with the severity degree of LA.The emotional memory for positive and neutral vanlence pictures is impaired but the emotional memory for neutral is relatively reserved in patients with LA in pictures recognition phase.It suggests that impaired emotional memory with different valences may be related to different neuromechanisms.

Linalool, as a major volatile compound, is widely distributed in natural plant essential oil. In addition, it can also be artificially synthesized. Linalool is used frequently as an important ingredient of perfumes and household detergents. It is still employed in food flavor and industries. Besides, linalool has some positive effect on healthcare. Many studies have showed that linalool exhibited a variety of pharmacological activities, including analgesic, anxiolytic, sedative, anti-inflammatory, anti-tumor and anti-bacterial effects. Therefore, linalool will be a promising agent for clinical application. This article reviews the pharmacological effects and formulation studies of linalool so as to provide a theoretical basis for its further development and utilization.

Objective To evaluate the value of the change of B-type natriuretic peptide(BNP) in predicting weaning outcome of patients with mechanical ventilation in ICU.Methods We carried out a prospective cohort study on patients in ICU at Fuxing Hospital from July 2013 to January 2014.Patients expected to use mechanical ventilation for more than 24 hours were enrolled in our study.The plasma concentration of BNP was measured at the beginning of spontaneous breathing trial(SBT) and 2 hours after.According to the outcome of SBT,patients were divided into SBT failure group (group A),weaning failure group (group B) and weaning success group (group C).The levels of BNP before and after the SBT were compared among three groups.The receiver operating characteristic (ROC) curve analysis was used to evaluate the changes of BNP (△BNP) and the rate of change (△BNP％) in predicting weaning outcome.Results A total of 56 patients were enrolled in our study,12 in group A,11 in group B and 33 in groupC.In groupC,both△BNPand△BNP％ [7.0,(-1.2,45.5) ng/L;6.1 (-2.1,11.5)％]were significantly lower than those in group A [88.0 (58.0,140.0) ng/L,P ＜ 0.05;20.5 (15.3,40.3) ％,P＜0.001]and group B[46.0 (17.5,91.2) ng/L,P＜0.001;24.3(13.0,32.5) ％,P＜0.001].The area under ROC curve (AUC) of △BNP％ to predict weaning success was 0.88 [95％ CI 0.79-0.97;P ＜0.001] and the cut-off value is 13.4％ with relatively high sensitivity(84.8％)and specificity(82.6％).The AUC of △BNP to predict weaning success was 0.80 [95％ CI 0.69-0.92;P ＜ 0.001] and the cut-off value is 80ng/L with high sensitivity 93.4％ and mediocre specificity (47.9％).Conclusion Either △BNP％ or △BNP in the SBT can predict weaning outcome,in which △BNP％ seems better than △BNP.

Objective Retrospectively investigate the application of anterolateral thigh flow-through flap in reconstruction of the extremities,to estimate its role and characteriscts.Methods From March,2010 to January,2016,anterolateral thigh flow-through flap was performed for reconstruction of the extremities in 87 patients (56 males,and 31 females).Patient ages ranged from 13 to 68 years,average of 34.4 years.Of all cases,there were 37 legs,21 ankles or foots,1 arm,19 forearms,and 9 hands.The role and result of anterolateral thigh flow-through flap was analyzed retrospectively.Results The result showed that when anterolateral thigh flow-through flap was transferred,which simutaneously played various roles as follows:①rebuilding main vascular defect,to revascularise the distal limb.② preserving recipient vessels,to prevent flow impaired.③rebulding recepient vessel defect.④ protecting vascular anastomosis and preserving recipient flow simultaneously.⑤avoiding the dilemma of end-to-side anastomosis when recipient vessels is deep.⑥ balancing blood flow,the blood supply of the flap was more stable.⑦ linking another tissue in a series fashion,to achieve complex reconstruction.Vascular compromise occurred in 3 cases after surgery,total necrosis occurred in 1 case and partial necrosis in 1 case after reexploration.One case presented deep infection and secondary with renal failure,and received amputation.Local infection presented in 3 cases,wound dehiscence in 2 cases.All the other flaps survivled uneventfully,and its texture and color was normal.In donor site,local infection occurred in 1 case,wound dehiscence in 2 cases.Conclusion Anterolateral thigh flow-through flap has function of many sided reconstruction,which is able to play a vital role in reconstruction of the extremities.

Objective To study the role of serum Hcy level change in predicting the effects of pemetrexed (PEM ) chemotherapy for treating the patients with advanced lung adenocarcinoma .Methods Fifty‐seven cases of lung adenocarcinoma treated by the PEM chemotherapy were retrospectively analyzed .The fasting venous blood was collected for detecting serum Hcy level before chemotherapy and at the end of 2‐week chemotherapy .The clinical characteristics ,Hcy level before and after chemotherapy and the relation between the Hcy level with clinical effect were statistically analyzed .Results In the therapeutic effects evaluated by the im‐aging examination during treatment process ,there were no case of complete remission (CR) ,19 cases of partial remission (PR) ,22 cases of stable diseases(SD) and 16 cases of progressed diseases(PD) ,the objective response rate(ORR) was 33 .3% and disease control rate (DCR) was 71 .9% .Different clinical factors had no significant influence on the efficacy of PEM chemotherapy (P>0 .05) .In comparing the influence of Hcy level and Hcy level change on the effect of PEM chemotherapy ,the results showed that serum Hcy level before treatment had no obvious influence on curative effect ,DCR in the patients with normal serum Hcy level after treatment was significant higher than that with abnormal Hcy level ,ORR and DCR in the patients with decreased Hcy level after chemotherapy were significantly higher than those with increased Hcy level (P<0 .05) .Conclusion Monitoring the serum Hcy lev‐el change during the PEM chemotherapeutic process in the patients with advanced lung adenocarcinoma may be used in the predic‐tion of the chemotherapeutic effect .

Objective To investigate the emotional memory impairment in patients with primary insomnia (PI) and explore the neurobiological mechanisms underlying primary insomnia through emotional memory tasks involving different valance of emotional pictures.Methods Thirty patients with primary insomnia(PI group) and twenty healthy controls(HC group) were given emotional memory tasks using positive,neutral and negative valence images.The emotional memory was evaluated by the recognition of emotional pictures.Results Compared with healthy controls (positive (11.60±4.00) , neutral (11.05± 3.73) and negative (12.60± 2.06) , respectively), patients with PI (positive (11.30±3.75),neutral (11.47±3.21) and negative (11.43±4.12) ,respectively) showed no significant difference in appraisal of the emotional pictures (P＞0.05).Compared with healthy controls (43.40± 4.88) for the emotional images memorizing task,patients with PI (39.40±6.43) exhibited evident deficit of all emotional images (P＜0.05).Furthermore, the accuracy in recognizing both positive (12.60± 2.42) and neutral (12.87±3.18) valence pictures were significantly lower in patients with P1 than those in healthy controls(positive (14.05±2.19) and neutral (14.75± 1.80)) (P＜0.05).There was no significant difference in negative stimulus between PI group(13.93±1.76) and HC group(14.70±1.59) (P＞0.05).Conclusion The results suggest thant emotional memory is impaired in patients with PI.Moreover,the emotional memory for positive and neutral vanlence pictures is impaired but the emotional memory for negative is relatively spared in patients with primary insomnia.The results also indicate that impaired emotional memory with different valences may relate with distinct neuromechanisms.

Objective To evaluate the efficacy of the treatment of hilar biliary malignant obstruc tion with multiple stent drainage.Methods One hundred and twenty-seven patients with malignant biliary hilar obstruction were enrolled.The obstructions at the common hepatic duct within less than 1 cm to the junction of the left and the right hepatic duct were found in 66 cases,at the proximal common hepatic duct and the left and the right hepatic ducts in 45 cases,at the right hepatic duct in 5 cases and at the both left and right hepatic duets in 11 cases.Sixty-six patients received stent placement through the right biliary ducts and the common bile duct by puncturing the right mid-axillary line.The other 37 patients received 2 stents placement (disposed"Y"style) through the left and the right hepatic duct punc turing routway.Seven patients received 2 stents placement (disposed"┌"style) through the right hepatic duct and the common bile duct with a stent placed between the left and the right hepatic duct.Three patients had right hepatic duct stent placed first,followed by right hepatic duct and common hepatic duct stent. Twelve patients had stents placed in the right hepatic duct with external drainage from the left hepatic duct. Two patients had multiple strictures at the right hepatic duct,who got multiple external drainages.The total serum bilirubin levels were measured pre-and post-operatively.Results One hundred and twenty-seven patients with bi[iary obstraction had internal stents placed for drainage.The average total bilirubin levels among 121 patients were (283.4?175.4 )?mol/L pre-operation and (63.2?11.8)?mol/L post-operation (P
