Anxiety is usually generated because of the threatened feeling. The data of electrocardio, respiration, blood volume pulse and skin conductance signals were collected. The arithmetic of Relief were used for the feature selection and combined with k-Nearest Neighbor (kNN) arithmetic and Support Vector Machine (SVM) arithmetic for classification. The results show that the combination of Relief-SVM is better than combination of Relief-kNN on the recognition of anxiety state. The emotion recognition based on multi-physiological signals is superior to that based on one single signal.

Objective This study is to investigate the protective effect of creatine phosphate so-dium on circulatory function in unilateral total knee replacement surgery using bone cement implanta-tion.Methods Forty patients undergoing unilateral total knee replacement surgery with bone cement were randomly assigned into 2 groups:test group (group CP,n=20)and control group (group NS, n=20).The easophageal doppler ultrasound probe was placed at the level of the third rib transorally after induction in each patient.In group CP,creatine phosphate sodium (2 g in 100 ml normal saline) was infused (within 30 min)at 30 min before the operation,as well as normal saline 100 ml in group NS.SBP,DBP,HR,SpO2 ,PET CO2 and BIS were monitored and recorded before (T0 )and 1 (T1 ),3 (T2 ),5 (T3 ),10 (T4 )min after insertion of bone cement.Cardiac output (CO),stroke volume (SV)and left ventricular end-diastolic volume (LVEDV)were simultaneously monitored and recorded with esophageal doppler ultrasound.WhileⅡ-lead electrocardiogram were recorded to monitor ven-tricular arrhythmia perioperatively.Results SBP,DBP and HR decreased at T2 and T3 in group NS, and were lower than those in group CP (P <0.05 );Meanwhile,compared with group CP,CO and SV were significantly lower,while LVEDV was significantly higher in group NS (P <0.05 ).Com-pared with T0 ,CO and SV decreased and LVEDV increased at T2 and T3 in group NS (P <0.05 ). After insertion of bone cement,the incidence of arrhythmia in group CP was obviously lower than that in group NS (P < 0.05 ).Conclusion Pretreatment with creatine phosphate sodium can effectively prevent the incidence of bone cement implantation syndrome (BCIS)by stabilizing hemodynamic in elderly patients undergoing total knee replacement with bone cement.

Objective:To investigate the expression of tumor necrosis factor-α(TNF-α)and soluble intercellular adhesion molecule -1(sICAM-1)in blood serum and gingival tissue in rat periodontitis model in normoxia and chronic intermittent hypoxia environment. Methods:32 male SD rats were randomly divided into 4 groups(n =8):normoxia control group(group A),normoxia periodontitis group(group B),hypoxic control group(group C)and hypoxia periodontitis group(group D).The periodontitis models were estab-lished by ligating the bilateral maxillary second molar and raised by periodontitis diet.The rats in hypoxia groups were raised under chronic intermittent hypoxia environment,while those in normoxia groups were raised under normoxia environment.After 8 weeks, plaque index(PLI),bleeding index(BI)and attachment lost(AL)were measured,TNF-αand sICAM-1 concentrations in blood serum and gingival tissue were measured by ELISA.Results:TNF-αand sICAM-1 concentrations in blood serum and gingival tissue in group A were higher than those in group B,C(P ＜0.05);in group D were lower than in group B and C(P ＜0.05).TNF-αand sICAM-1 levels in blood serum and gingival tissue were positively correlated with AL(P ＜0.05).Conclusion:In chronic intermittent hypoxic environment TNF-αand sICAM-1 may aggravate periodontitis,and promote the inflammatory response to peripheral vascular system.
