Objective To investigate the clinical significance of serum sialic acid (SA) in the diagnosis and treatment of IgA type multiple myeloma (MM). Methods The level of serum SA in 50 healthy subjects and 70 patients with MM were determined. Results In MM group, there were 25 cases of IgA type, 51 cases of other than IgA type (40 cases of IgG type, 7 cases of light chain type MM, 4 cases of non-secreting type MM). In healthy subjects, patients with IgA, IgG, light chain, non-secreting types and other than IgA type, the serum SA levels were (570.33 ± 67.72) mg/ L, (1289.24 ± 325.42) mg/ L, (585.88 ± 159.12) mg/L, (600.77 ± 126.90) mg/L, (590.50 ± 100.86) mg/L, and (588.39 ± 150.90) mg/L. The serum SA level of IgA type patients was higher than those of healthy subjects and other types (all P<0.01), and there was no significant difference among the other groups (all P> 0.05). The serum SA level of IgA type patients had positive correlations with serum IgA, globulin, bone marrow smear myeloma cell population and ESR (r values were 0.699, 0.753, 0.504, and 0.732, all P< 0.05); the serum SA level of IgA type patients had negative correlations with serum albumin, IgG, hemoglobin and platelet (r values were -0.712, -0.505, -0.629, and -0.596, all P< 0.05). The serum SA level of IgA type patients had no correlation with leukocyte, serum creatinine, serum IgM, lactic dehydrogenase, serum calcium, C-reactive protein and β2-microglobulin (all P>0.05). The level of serum SA in IgA type patients decreased with the improvement of the condition, and increased with the severity of the disease. Conclusions In MM patients, serum SA level in IgA type is high. The serum SA is an index for reflecting the tumor load capacity, and can evaluate the therapeutic efficiency of IgA type MM patients.

Objective To observe the effects of target-controlled infusion ofpropofol on hemodynamics during anesthesia induction in intracranial aneurysms interventional treatment.Methods Ninety patients in intracranial aneurysms interventional treatment were divided into three groups by random digits table method with 30 cases each:control group (group C),plasma drug concentration in target controlled infusion group (group P) and effect of chamber drug concentration in target controlled infusion group (group E).The induction of anesthesia:patients in group C were single intravenous injected with propofol of 2 mg/kg; patients in group P were set target plasma concentration of propofol with 4 μ g/ml.Patients in group E were set the effect target concentration of propofol with 4 μ g/ml.Three groups were set the concentration of remifentanil 4 ng/ml with plasma controlled infusion,and cisatracurium was injected with 0.2 mg/kg.Electrocardiogram,mean arterial pressure (MAP),heart rate (HR),end-tidal pressure of carbon dioxide,bispectral index,pulse oxygen saturation were continuously monitored.Before the time of induction (T0),immediately before intubation (T1),after intubation 1 min (T2),3 min (T3),5 min (T4),10 min (T5),arterial pressure and HR were recorded and the number of using vasoactive drugs were recorded.Results The level of MAP and HR among three groups at T0 had no significant difference (P ＞ 0.05).The level ofMAP and HR in three groups at T1 was significantly lower than that at T0.(P ＜ 0.05).The level of MAP and HR in group P was lower than that in group E and group C,and there was significant difference (P ＜ 0.05).The incidence of using vasoactive agen in group P was significantly lower than that in group C [6.7％(2/30) vs.40.0％ (12/30)],and there was significant difference (P ＜0.01).Conclusion Hemodynamics is relatively stable during anesthesia induction using plasma target controlled infusion with propofol in patients undergoing interventional therapy for intracranial aneurysm.

Objective To explore the surgical methods and clinical applications of single operation hole for thorascopic surgery in treatment of encapsulated effusion with atelectasis after thoracic injury.Methods From October 2011 to October 2013,using single operation hole for thorascopic surgery treating encapsulated effusion with atelectasis in 56 cases after thoracic injury,35 males and 21 females,aged 21-68,mean 34 years old.The left encapsulated effusion with atelectasis in 31 cases,the right of encapsulated effusion with atelectasis in 25 cases,atelectasis in 43 cases,partial atelectasis in 9 cases,total atelectasis in 4 cases.Before thorascopic surgery,routine thoracentesis or (and) closed thoracic drainage were performed,but ineffective.Surgical approach for anesthesia with the thorascopic surgery encapsulated effusion dissection + suction drum lung surgery.Thorascopic surgery were completed in single operation hole,postoperative chest tube into the hole from observation.Results The operation time was 55-120 min,average 75 min; blood loss was 25-150 ml,average 65 ml.All patients underwent in single operation hole.The postoperative hospital stay was 7-19 d,average 11.2 d.There were no perioperative mortality and major complications.Conclusions The single operation hole for thorascopic surgery in treatment of encapsulated effusion with atelectasis after thoracic injury is exactly effective and simple.It can be used as an effective treatment.

Objective To investigate the changes of cardiac structure and function in type 2 diabetes mellitus (T2DM), analyze the related risk factors of heart failure, and improve the awareness of the effect of diabetes on the heart. Methods Randomly selected 170 cases of T2DM patients As the object of study, 170 cases of non diabetic patients as con-trol group, according to whether complicated with heart failure were divided into heart failure patients and non heart failure patients.Comparison of each group left ventricular posterior wall thickness, left ventricular end diastolic diameter, left ven-tricular end systolic diameter, left ventricular ejection fraction, E/A ratio Differences, analysis of the related risk factors of heart failure by logistic regressive.Results T2DM group left ventricular posterior wall thickness, left ventricular end diastolic diameter and left ventricular end systolic diameter increased , Left ventricular ejection fraction decreased, E/A ratio de-creased, were statistically significant difference compared with the control group (p <0.05).These differences are mainly come from non heart failure patients.Logistic regression showed that factors in patients with diabetes duration, HbA1c, com-pliance and complications of hypertension, coronary heart disease, is a risk factor for heart failure complicated with T2DM (all p<0.01).These may be the risk factor for diabetic patients with heart failure.Conclusion Diabetes can cause cardiac remodeling, systolic and diastolic dysfunction maybe some T2DM patients.They did not show symptoms of heart failure in the clinical, but their Cardiac structure and function are abnormal.We should pay attention to the cardiac function examination and early evaluation, prevention of risk factors, to avoid the occurrence of heart failure.

OBJECTIVETo explore the working mechanism and age-related change of the conflict processing system of the frontal cortex.

METHODSFifteen normal elderly people and 15 youth were performed a modified Eriksen flanker paradigm, while event-related potential (ERPs), which include 32 systerm electroencephalography, reaction time and correct rate were recorded.

RESULTSThe elderly group showed a distinct effect of reaction time and effect of conflict in the respond level compared with the youth group. The elderly group had a longer time window of N380 and same amplitude as the youth group. Low resolution brain electromagnetic tomography (LORETA) showed the bilateral temporal lobe and the dorsolateral prefrontal cortex (especially right) were activated in the youth group, while the left temporal lobe, the left dorsolateral prefrontal cortex and left medial frontal gyrus were activated in the elderly group.

CONCLUSIONWhen conflict stimuli existed in the response level, old people showed frontal interference control hypofunction. N380 reflected the activation of the left dorsolateral prefrontal cortex and the left temporal lobe during response selection and executive control processing in older people.
