The interaction between the anti-Ractopamine (Rac) monoclonal antibody and the Rac derivation immobilized on the sensor chip surface was studied with surface plasmon resonance (SPR) biosensor. A continuous detection method based on the linear response during the association phase was developed. The sensor chip surface was regenerated after several tests performed continuously, thus the detection step was simplified and the life span of the chip was prospected to be prolonged. The detection was performed as an inhibitive immunoassay. The mixture of anti-Rac monoclonal antibody and the sample flowed over the surface with Rac derivation was immobilized. The relative response was in inversely proportion to the concentration of Rac. The detection limit was less than 4 μg/L with a detection time of 15 min.

The fabrication and experimental test results were presented for a micro-electro-mechanical systems (MEMS)-based gas chromatography column. Compared with conventional column, this micro-gas chromatography column is suitable for on-line analysis and monitoring because of the small size, rapid analysis and other characteristics. These 0.5, 1 and 3 m GC columns were fabricated using a deep reactive-ion etching (DRIE) and were coated the stationary phase via a dynamic coating procedure. These GC columns perfectly separated the mixture of benzene, toluene and o-xylene in less than 200 s, where, the 3.0 m of the GC column achieved) a high resolution of 14.3 between toluene and o-xylene and yielded approximately 6160 plates. Moreover, the effect of separation performance for different column length were examined and compared. These GC columns are suitable for the application of a variety of disciplines, including environmental analysis, methane gas probes and homeland security.

Objective - To optimize the extraction and quantification methods for the determination of S phenylmercapturic acid - Methods (SPMA) in urine with performance liquid chromatography mass spectrometry. The urine was hydrolyzed with 50.0% sulfuric acid. The hydrolysate was purified by solid phase extraction column. Purified samples were separated by C18 chromatographic column and detected by tandem mass spectrometry. The isotope labeled SPMA was used as the internal Results - standard. The internal standard curve was used for quantification. The linear range of SPMA was 0.50 50.00 μg/L with the correlation coefficient of 0.999 8. The detection limit and the lower limit of quantification were 0.05 and 0.17 μg/L, - - - - respectively. The recovery rate was 97.0% 102.0%. The within run and between run relative standard deviation were 0.6% 1.0% - and 1.7% 6.5%, respectively. The mass concentration of urinary SPMA in the occupational benzene exposure group was - vs P higher than the non occupational benzene exposure group by this method (median: 2.81 0.28 μg/g creatinine, <0.05). Conclusion Compared to the national standard method, this optimized method of solid phase extraction and internal standard for quantification eliminates the matrix effect. This method is accurate and precise, and is suitable for the determination of SPMA acid in urine.

The differences in the total effective rate between the light stimulation group and the moderate stimulation group, as well as the strong stimulation group, were statistically significant (both P<0.05). There was no significant difference in the total effective rate between the moderate stimulation group and the strong stimulation group (P>0.05). The total effective rate was 83.9％ in the dog-days acupoint application group, versus 45.4％ in the Magic Acupuncture Patch group, and there was a statistically significant difference between the two groups (P<0.05). Conclusion: The efficacy of dog-days acupoint application in the prevention and treatment of CB is better than that of Magic Acupuncture Patch; the degree of stimulation is the basis for the effect of dog-days acupoint application on prevention and treatment of CB, and the moderate and strong stimulations are more appropriate.

Objective: To observe the efficacy of long-retaining scalp acupuncture plus interactive training in improving upper- extremity dysfunction in cerebral stroke patients. Methods: Ninety-five patients with upper-extremity dysfunction after cerebral stroke were randomized into two groups, with 48 cases in the treatment group and 47 cases in the control group. Conventional internal medicine treatment was offered to both groups. In both groups, Anterior Oblique Line of Vertex-temporal (MS 6, the middle 2/5) and Posterior Oblique Line of Vertex-temporal (MS 7, the middle 2/5) were selected from the same side of the brain lesion (the side apposing to the hemiplegic limb) for scalp acupuncture treatment. In the treatment group, the scalp acupuncture needles were retained for 7 h, in combination with interactive training, while the needles were also retained for 7 h in the control group but without interactive training. Prior to treatment and at 2-week and 4-week treatment, the two groups were scored using the functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK) and simplified Fugl-Meyer assessment-upper extremity (FMA-UE). Results: The total effective rate was 97.9％ in the treatment group, higher than 74.5％ in the control group (P<0.01). The FTHUE-HK score was higher at 2-week and 4-week treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FTHUE-HK score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FTHUE-HK score was higher in the treatment group than in the control group, showing significant between-group differences (both P<0.05). During the whole treatment process, the treatment group had higher FTHUE-HK scores compared with the control group, but there was no statistical significance comparing the change of the score between the two groups at 2-week treatment (P>0.05), while the between-group difference in the change of the score was statistically significant at 4-week treatment (P<0.05). The FMA-UE score was higher at 2-week and 4-weeks treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FMA-UE score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FMA-UE was higher in the treatment group than in the control group, and the between-group differences were statistically significant (both P<0.01). The FMA-UE score rose gradually with the increase of treatment session, and there was statistical significance comparing the change of the score between the two groups at 2-week and 4-week treatment, respectively (both P<0.05). Conclusion: Long-retaining scalp acupuncture plus interactive training results in more significant efficacy than long-retaining scalp acupuncture alone in improving the upper-limb dysfunction after cerebral stroke and the advantage becomes more notable after 2-week consecutive treatment.
