A sensitive, rapid and specific liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for quantification of gabapentin in human plasma has been developed. After a single plasma protein precipitation with methanol, gabapentin and metformin (internal standard) were chromatographed on a Inertsil ODS-3 column (50 mm x 2.1 mm ID, 3 microm) with mobile phase consisting of methanol-0.2% formic acid aqueous solution (80:20, v/v) at a flow-rate of 0.2 mL x min(-1). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 172 --> m/z 154 and m/z 130 --> m/z 71 were used to quantify gabapentin and metformin, respectively. The run time was 2.2 min. The linear calibration curve was obtained in the concentration range of 40.8-8.16x10(3) ng x mL(-1). The lower limit of quantification was 40.8 ng x mL(-1). The intra- and inter-day precision (RSD) was less than 12%, and the accuracy (RE) was within +/-6.4% calculated from quality control (QC) samples. The method was used to determine the concentration of gabapentin in human plasma after a single oral administration of 600 mg gabapentin capsule to 20 healthy male Chinese volunteers. The method was proved to be selective, sensitive, rapid and suitable for pharmacokinetic study of gabapentin in human plasma.

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.

BACKGROUND:Screw fixation of the fractured vertebral body can share the stress of implant, increase fixing strength, and help to maintain the stability of late fracture. However, whether it can assist reduction using fracture vertebral screw, but no relevant clinical reports were found at present. OBJECTIVE:To explore the effectiveness of self-designed screw-assisted reduction of fractured vertebrae. METHODS:161 cases of thoracolumbar fracture who had been hospitalized between June 2001 and June 2009 were enrol ed in this study, including 101 males and 60 females, at the age of 22-67 years, averagely 36 years. By Denis classification, 64 cases affected burst fractures and 97 flexion-compression fractures. Fracture levels involved T11 (9 cases), T12 (63 cases), L1 (74 cases) and L2 (15 cases). The self-designed method of reduction assisted with screw insertion was used. The efficacy of this reduction method was evaluated by operation time, intraoperative bleeding, fracture union time, height ratio of anterior borders of injured and normal vertebrae, sagittal Cobb’s angle, and reduction of fragments.
RESULTS AND CONCLUSION:The operation time ranged from 60 to 150 minutes, averaging 80 minutes. The intraoperative bleeding ranged from 67 to 750 mL, averaging 98 mL. The fol ow-up time ranged from 16 to 42 months in 161 patients. Fracture union time ranged from 10 to 18 weeks, averaging 12.6 weeks. The ratio of anterior heights and sagittal Cobb’s angle of fractured vertebrae were significantly improved from (54.39±9.60)%and (22.55±7.90)° respectively preoperati on to (82.80±6.63)%and (8.91°±5.85)° 12 months postoperation (P<0.05). The size of spinal canal was increased by (46.5±2.6)%postoperatively. CT scan revealed satisfactory fragment reduction and no deep infection appeared. These findings suggest that our self-designed screw-assisted reduction of the fractured vertebrae can improve the reduction quality in the treatment of thoracolumbar fractures.

OBJECTIVE: To survey the prevalence of obstructive sleep apnea-hypopnea syndrome(OSAHS) in adults aged over 60 years in Dongying city,and analyze the risk factors and the extent of damage to the quality of life for the elderly to provide the basis for prevention and treatment of OSAHS people. METHOD: One thousand subjects were derived from a random cluster sampling in seven districts of Dongying city:they were asked to answer the questions from questionnaires. According to the questionnaire scoring, 100 subjects in high-risk group were selected randomly to make polysomnography monitoring for a whole night,so that the prevalence of the disease was calculated and the related risk factors were analyzed; elderly patients diagnosed with OSAHS were asked to assess the quality of life assessment questionnaire by face to face to understand the quality of life dimensions injury. RESULT: The actual number of completed surveys was 934, and the efficiency was 93.4%. The estimated prevalence of OSARS in elder people defined by apnea-hypopnea index (AHI ≥ 5) was 32.5%; Multivariate analysis revealed that age smoking, family snoring,neck circumference, waist circumference, and abnormality of the upper airway were respectively independent risk factors of OSAHS,and the abnormalities of the upper airway had the most obvious impact on AHI. The damage caused by OSAHS to the quality of life for elderly people followed their daily work life, social relationships, symptoms, alertness, emotional, general health, symptoms. CONCLUSION The estimated prevalences of OSAHS in elder people were high. Actively promoting good habits to older people, weight loss, early detection and correct upper airway abnormalities may reduce the estimated prevalence of OSAHS. In the treatment process, the patient's physician should pay attention to their emotional and groom their psychological problems to improve the quality of life in elder people.
